1.2  The main functions of the fixture are as follows. 

  • Fixed a group Batteries and the battery slice and the bracket are a battery pack.
  • Make the position of the solder joints of the assembled battery pack welding parts accurate and stable.

1.3  The function of welding process is as follows

  •  Manually push in the battery pack fixture Automatic operation function when in Automatic Operation Function of Battery Packaging Tool after Manual Pushing in Position.
  • Electric positioning and pressing/compression function Features.
  • Double-sided simultaneous automatic spot-welding function.
  • Manual 90-degree change of welding head Features (to be customized).
  • Laser positioning and alignment Features.
  • Optional front and back discharge Optional pre-discharge and post-discharge functions
  • Wired remote control function of movable man-machine.
  • Automatic poor welding current alarm and repair welding function. (This function is available when supporting high frequency inverter and transistor welding power supply)

1.4  Equipment Action Flow 

Insert the battery cell/bracket/battery into the fixture→→Place the fixture to the sensing position→

→Automatic spot welding of equipment Finish sending out to the reclaiming position→→Remove the battery pack from the fixture→→Go to the next production escape ring Core/bracket/battery pack fixture->placement fixture to induction position->automatic spot welding of equipment to feed- out position->removal of battery pack from fixture->next production escape ring

1.6The overall dimensions and appearance of the equipment (Width*length*height):1000*1400*1680(This size is for reference only).

(The appearance of the initial version will be changed after the upgrade without notice.)

2.  Main functional characteristics:

  • Adopt a universal 6-axis numerical control system to make the control more standardized and the product more adaptable.
  • Full touch screen man-machine interface. Full Touch Screen Human-Machine Interface.
  • The welding head is driven by a flexible servo motor. Y, Z axis servo drive, double-sided X1/X2 axis spot welding at the same time, flexible servo motor drive of spot-welding head.
  • Workstation design is oriented to the production site, with simple operation and setting, low operating threshold, easy to learn and use.
  • Equipment with Semco Customer Selection Welding Power (This project is an optional project. It can be equipped with several welding power sources, some of which have different functions due to different welding power sources. Special welding power supply can also be selected individually.)
  • The dual welding heads are convenient to manually change the direction, which solves the problem of the different horizontal and vertical cut angles of the solar cells (need to be customized)
  • The spot-welding program route can be designed arbitrarily without specific requirements.
  • After programming, the coordinates of each point can also be accurately corrected.
  • Automatic alarm for defective solder joints, manual control and automatic positioning repair welding (some functions when equipped with monitoring function welding power supply)
  • Automatic welding in and out of the workpiece, no human operation is required during the welding process.
  • The visual and transparent workstation design is conducive to the observation and understanding of welding in time.
  • Equipped with special adjustment and alignment tools to adjust the welding head and make the welding alignment work faster.
  • Production Counting
  • Replacing the product only needs to adjust the energy and transfer out the procedure without any other operation.
  • Store dozens of product welding procedures and parameters in the system.
  • It can be displayed once and twice as well as pattern programming.
  • Yes welding path CAD map function, U disk copy program can be used.
  • The new generation of portable remote-control man-machine interface operation mode design effectively reduces the inconvenience of workers.
  • It has the switching function of forward and backward forward.
