引出片与连接片方法 18650 lithium battery spot welding machine lead-out piece and connecting piece method

锂电池点焊机 引出片及为复杂,引出片与连接片的作用是将18650锂电池性能连接起来输出,主要体现在各种锂电池组当中,其主要点焊引出片和连接片的方法如下: The lead sheet of 18650 lithium battery spot welding machine is complicated. The role of lead sheet and connecting sheet is to connect the output of 18650 lithium battery performance, which is mainly reflected in various lithium battery packs. as follows:

1. Press the power switch of the double-head pulse spot welder to the "ON" position to turn on the power.

2. Confirm that the parameters of the battery equipment have been adjusted. According to the parameter setting table on the right, prepare the materials and related tools. Among the tools can be: double-head spot welder, knife set, crimping fixture, hexagon wrench. 设备参数时必须和品质工程确认,符合要求才能操作。 When debugging the battery spot welder equipment parameters, it must be confirmed with quality engineering to meet the requirements before operation. When spot welding 18650 lithium batteries, you must pay attention to the spot welding pull force. The pull force value must be within the quality inspection range.

3. Pick up a battery with the bottom of the negative terminal facing upwards. Take a lead-out piece with the round hole end on the lead-out piece. Spot-weld the lead-out piece to the middle position of the negative end of the 18650 lithium battery.

4. Turn the lithium battery pack with the lead-out piece facing inward, take a connecting piece, place the connecting piece on top of the lead-out piece, and spot-weld the connecting piece to the middle of the negative terminal of the battery in line with the lead-out piece.

5. Pick up another battery, with the bottom of the negative terminal facing up, and solder the exposed end of the connecting piece of the first battery to the middle of the bottom of the negative terminal of the second battery.

6. Place the battery packs that have been spot welded in series on the pressing fixture, and press the battery packs together in the middle, so that the two batteries are tightly connected together, and the two batteries are aligned.

7. Put the compacted battery pack into the next station, clean up the work surface and turn off the power switch of the spot welder.

引出片与连接片注意事项: 18650 lithium battery spot welding machine lead-out piece and connecting piece note:

1. The specifications of the lead-out sheet must conform to the material BOM specifications.

2. There should be no missing phenomena such as missing welding, false welding, explosion, obvious burrs and so on.

3. The number of solder joints in the lead-out piece / connecting piece is not less than 6 points.

4. Do not make the pads fall off during operation. If they fall off, you must reattach the pads to work.

铜针针尖发黑时,用挫刀将铜针黑点挫去再重新点焊作业。 5. When the copper needle tip of the 18650 lithium battery spot welding machine becomes black, use a frustrating knife to remove the black spot of the copper needle and restart the spot welding operation.

6. If there are abnormalities such as smoke and abnormal sounds from the machine, turn off the power switch in time, stop the machine and report to the supervisor.
