Description

Finished polymer battery test fixture

technical field

The utility model relates to a polymer battery detection device, in particular to a tooling fixture for connecting polymer battery testing equipment with signals of the polymer battery to be tested.

Background technique

导线头长仅1.6±0.25mm。测试完成后，要求导线的外绝缘皮不能有压痕，导线头不能变形。目前大多数电池生产厂家使用的工装是，导线头放在两个铜电极测试端上，用两个硬压头压紧。由于导线绝缘皮不能有压痕，所以这两个压头面积很小。由于压头只能压在导线头上，导线头必须放在很准确的位置，靠前一点压头压到绝缘皮，靠后一点又压不住导线头。导线头1.6mm长的范围很难控制，全靠人的熟练程度，这样给车间作业带来了很大的困难：经常压不住，重新再压一次，效率较低；有时压到导线绝缘皮，对导线绝缘皮造成压痕，导致废品。The design and manufacturer of polymer batteries often need to test various parameters of the finished battery through battery testing equipment, and the fixture is a device that connects the battery under test to the battery testing equipment. When testing, it is necessary to connect the finished battery with the battery testing equipment, so that the information of the battery can be accurately transmitted to the battery testing equipment, so that accurate testing can be carried out. Therefore, fixtures are an important part of the battery testing process. Due to the large amount of battery testing in the workshop operation, high testing efficiency is required, which puts forward higher requirements for the tooling and fixtures for battery testing. The characteristic of the polymer battery is: After the battery is packaged, two wires are drawn out. For example, the lengths of the two wires of a battery of one specification are 17±0.8mm and 14.61±0.8mm respectively, and the outer diameter of the wires

The lead length is only 1.6±0.25mm. After the test is completed, it is required that the outer insulation of the wire should not have indentation, and the wire head should not be deformed. The tooling used by most battery manufacturers at present is that the lead wires are placed on the two copper electrode test ends and pressed tightly with two hard pressure heads. Since the wire insulation cannot have indentations, the areas of the two indenters are very small. Because the indenter can only be pressed on the wire end, the wire end must be placed in a very accurate position, and the indenter is pressed to the insulation skin a little ahead, and the wire end cannot be pressed a little behind. It is difficult to control the 1.6mm length of the wire head, it all depends on the proficiency of the person, which brings great difficulties to the workshop operation: often cannot be pressed, and the efficiency is low; sometimes the insulation of the wire is pressed , causing indentation to the wire insulation, resulting in waste.
