Description

Platinum Plating Line

General Description

A fully automatic line installed circa 2015 which is in excellent condition. Commissioned but never run in production.
Designed for the application of Platinum Plating on Turbine Blades but offering the possibility of conversion to process other high value components.

The equipment is arranged in a straight line with the Load/Unload station at one end for efficiency of operation. The work is carried automatically through the line by an enclosed transporter complete with blow down fans for fume control and motorised raise lower and traverse speed controlled via inverter drives.

A highly sophisticated supervisory control and data acquisition (SCADA) system is provided incorporating a Siemens PLC linked to a Fujitsu computer running Excelerplate software to provide the man machine interface (MMI).

As to be expected in this precise process, important parameters are carefully monitored and controlled with the resultant information data logged. Solution temperatures for example are controlled to plus/minus one degree Celsius and fully automatic dosing is included.

All tanks are provided with actuated stainless steel lids with automatic operation linked to transporter operations.
This represents a unique and rare opportunity to acquire a highly sophisticated line in excellent condition offering considerable savings over the buy new price.

Principle of Operation

Components are manually loaded onto jigs by an operator and positioned onto a trolley which is located at the front end of the load station ready to be collected by the transporter and transferred through the process as programmed.

The human machine interface unit (HMI) displays current status of system indicating status of all float level controls, solenoid valves, process heating devices, process temperatures, solution conductivities, limit switches, proximity switches, emergency stop circuits, plant alarms etc. which are all controlled.

Each of the five platinum plating tanks are equipped with electrojet external electric tank heaters automatically controlled to manage the chemical temperatures in each tank.

Platinum process plating time is estimated between 60-90 minutes per tank.

When 90% of the total process plating time has elapsed components will be automatically transported back to the load/unload station for inspection.
Plating thickness will be tested to ascertain the plating thickness.

Components will be re-jigged after testing and re-plated to obtain the required thickness.
Each of the five platinum plating tanks are monitored for pH concentration, a fall in pH level will initiate the operation of the associated ammonia reagent dosing pump. Contents monitoring is undertaken via float switch permitting automatic replenishment of levels with DI water from the DI water post dip tank.

Provision is made to automatically dose platinum planting P salts into each of the plating tanks via the operation of the associated P salts dosing pumps. This is from concentration data gained from the associated analyser system.

To contain and control any fumes or steam that may be liberated from the process solutions each of the tanks are fitted with pneumatically actuated lids, automatically controlled by the PLC programme to open and close when flight bars are being loaded or removed from the tank.

Tank mounted lip extraction ducts permit drawing off excessive levels of chemicals to the pump sump.

The maximum efficiency of the fume extraction when tank lids are open to allow flight bar movement into or out of process tanks extraction rate will be increased by adjustment of the associated pneumatically actuated damper.

The pre-plate ultra-sonic tanks are monitored for pH concentration, a fall in pH level will initiate the operation of the associated ammonia reagent dosing pump.

Both pre-plate ultra-sonic tanks contents are heated by electrical pan heaters, contents levels are monitored by integral float switches and tank contents agitated by externally mounted recirculation pumps. Contents monitoring is undertaken via float switches permitting automatic replenishment of levels with DI water from the DI water feed.

Both DI water post dip tanks are equipped with electrojet external electrical tank heaters with automatic control to manage the contents and temperatures in each tank, contents levels are monitored by integral float switches and tank contents agitated by externally mounted recirculation pumps. Contents monitoring in undertaken via float switch permitting automatic replenishment of levels with DI water from the DI water feed.
Off Line Components Loading/Unloading

Components are received from the preparation area prior to being processed through the auto plating facility.

Mobile trolleys are used to support flight bars onto which components and anodes are attached. Each component has a unique bar code/part ID..

When a flight bar is loaded with components and presented at the load/unload station the hand held barcode reader is used by the operator to register the identity of the flight bar and components and data feedback to the PLC control system.

This will be achieved by the operator manually scanning in the barcodes with his bar-code reader or manual entering the code on the HMI interface keyboard and recorded on paperwork accompanying the batch of parts.

This information will be used to determine the precise process requirements of the load and, on completion of the process routine, the system database will store historical data for individual parts for future traceability requirements.

The plant PLC control system is required to check the historical/SQL database as each part is scanned into the system, to prevent a part being processed more than once through the plating facility.

Once the component or flight-bar has been scanned then the operator selects a process sequence for the flight bar that is not permitted, a warning dialogue box will appear on the workstation screen.

At this point, the operator must either, remove the offending part(s) and re-scan the remainder, or an authorised person may log-on and override the restriction. If the latter action is taken, the database must record the action against the individual blade(s).

Transfer through process stations

Transporter Equipment

1 Off Fully motorised 100kg SWL Robotic transporter system, to operate in three modes.

Mode 1 Fully Automatic

Where all traverse and hoist movements automatically follow pre-set routes
and process times. Either in fixed time way or random control.

Mode 2 Semi-Automatic

Where all robotic transporter movements are under the control of the operator via a pendant or joystick or keyboard control

Mode 3 Maintenance

A ‘Works Engineer’ manual mode which is key or code lockable via the control panel. When in this mode, the transporter may be stopped in any position ‘off station’, i.e. for maintenance purposes.

Transporter Operation
The following description applies to the Automated Platinum Plating Transporter operation at the Load/Unload Station but generally applies to all stations. The transporter will run on a free standing runway in accordance with EN ISO 9001:2008. This will be complete with a 500 Kg 0.37 KW traverse and a 100Kg hoist motors.

The transporter has 3 operating modes, selected via the control unit with Emergency Stop function and operating modes, Fully Automatic (AUTO), Semi-Automatic (SEMI-AUTO) and Maintenance Mode (MANUAL

SEMI-AUTO Mode
All transporter movements are initiated by the operator using a manual pendant control unit and will be controlled and monitored by the PLC, to ensure that all safety interlocks remain active. For example, pressing the forward button on the pendant will cause the transporter to move forward at normal speed until the button is released. At this point the transporter will immediately ramp down to creep speed and will continue to move forward until it reaches the next station flag, where it will stop automatically when both station proximity switches are in contact with the flag. However, striking over travel limit switches at any time will stop the travel or hoist motor.

MANUAL Mode
All transporter movements are initiated by the operator using the manual pendant control and all travel and lift movements are carried out at creep speed for as long as the respective buttons are pressed (Failsafe Dead Man’s Handle operation) or until a fixed, end of travel, stop bracket is reached. In this mode there are no active safety or control interlocks, which enables the operator or maintenance personnel to recover from collisions etc.

AUTO and SEMI-AUTO Modes
Personnel protection is provided by a removable guards spanning the complete length of the operator side of the transporter. If the light guard is activated any time with an obstruction, all motive power to the transporter will be removed immediately. Audible and visual alarms will also be generated. Once the fault has been rectified, the system can be reset, and the transporter can be restarted.

There is an emergency stop push button mounted on the manual control pendant and an emergency stop light guard is installed along the entire length of the line at tank top level, which, when operated, will immediately cut all motive power to the transporter, and generate audible and visual alarms. Once the fault has been rectified, the system can be reset, and the transporter can be restarted.

Station Identification Proximity Switches are fitted on the far side of the Transporter carriage to identify which specific station the Transporter is on using binary code system.
The transporter upper framework is enclosed by a transparent canopy to prevent steam or fumes being released into the shop environment when loads are being transferred between tanks.

The canopy is fitted with two low energy axial flow pressurisation fans These fans operate automatically and will run continuously whilst the transporter is operating in Auto and Semi-Auto modes to pressurise the canopy with shop air, which works in conjunction with the tank-mounted lip extraction ducts to minimise the accumulation of steam and/or fume within the canopy, i.e. when the transporter is positioned above a lidded tank and the lids open to allow a flight bar to be loaded into or removed from the tank, any steam/fume liberated from the tank or components is pushed towards the lip extract ducts and is routed to the fume extraction scrubber.

The robotic transporter has features as follows:

• The traverse drive is by means of a variable speed motor and gear box under the control of a frequency inverter designed to give a smooth accelerating and decelerating speed ramp.
• The hoist mechanism is by means of a variable speed motor and gear box under the control of a frequency invertor designed to give a smooth accelerating and decelerating speed ramp.
• Anti-collision and over-run switches are fitted.
• Anti-lowering switches are incorporated on the transporter to stop one flight bar being lowered on top of another.

Track Support Structure

The track is manufactured from stainless steel beams supported by stanchions from the floor. Cross bracing is provided as required.

The self-supporting structure is in bolted sections lined and levelled on to the factory floor without the need for special foundations.

The complete structure is manufactured from stainless steel suitable for the operating environment.

Drip Shields
Tanks not fitted with exhaust ducts have PP drip shields in between to stop solution spillage.

Automatic Dosing For Platinum Processes
The platinum electroplate stations are provided with automatic dosing as detailed in the principles of operation above.

Fume Exhaust System
The extraction system includes the following major items of equipment: -

• Fume exhaust hoods
• Exhaust dampers
• Interconnecting trunking

Fumes are extracted via lip hoods at low level, into a plenum chamber and onwards through riser ducts into a manifold running at high level at the rear of the plant. The duct manifolds are fitted with removable access doors to enable internal cleaning and removal of any chemical residues for reclaim.
