This machine automatically feeds two process bars with 90 anodes from two magazines. Loads them on a carriage, with vacuum, which precisely locates these 90 nodes in individual cavities, transfers them to the die cut station where the process bars are cut off leaving .025″ long wires on the anodes, and moves it over to the anodes pick-up head. Where the process bars are discharged in bulk for reuse. The anodes’ pick-up head lines up with the carriage, which inverts the vacuum into pressure pushing the individual anodes into the pick-up head, with a vacuum.
The head transfers 90 anodes from the carriage to the lead frame, which places each anode in a pocket, that was previously filled with silver solder paste. The transfer head holds the anodes down on the lead frame. The lead frame is advanced and clamped in the silver solder reflow chamber which is heated and solders the anode onto the lead frame. At the end of the machine, the lead frame is cut into combs and loaded into a magazine for further processing.
PART CONFIGURATION – The equipment can be built for other size anodes.
LEAD FRAME – Supplied on reels with paper inlay.
MOTIONS – Most motions and actions are driven by stepper motors for very precise positioning.
SILVER SOLDER – Is designed through a dual dispensing head which is driven up and down and stepped 90 times by means of stepping motors.
CYCLE RATE – 22 seconds producing 15,000 anodes per hour.
MACHINE CONTROL – Touch screen controls are programmed to identify all operations. If a fault occurs at any of the 70 limit devices, the screen will identify the problem area, and what to do to correct the problem. It is possible to operate each section individually for set up purposes, run in jog mode, single cycle and many individual motions. There are exterior emergency stops allowing control from any position.
