Description

Multi-cell lithium-ion battery protection board test fixture

technical field

The utility model relates to the manufacturing technology of a lithium ion battery, in particular to a test fixture for a multi-section lithium ion battery protection board. the

Background technique

Generally speaking, printed circuit boards are the basic components of electronic products, and their main functions are to carry electronic components, transmit power and signals, insulate and dissipate heat. PCB boards have been widely used in many fields such as electronics, information, communication, medical treatment and aerospace technology. the

For the produced PCB board, it cannot be put into use directly, but the performance and function of the PCB board need to be tested first, and it can be put into use after confirming that there are no potential problems. The physical performance test is a very important part of it. As a kind of PCB, the lithium-ion battery protection board is smaller than the traditional PCB, especially the multi-section protection board has a precise structure and dense welding points. When inspecting one-section, two-section or multi-section protection boards, the wiring is difficult, the detection speed is slow, the wiring is wrong, the measurement is inaccurate, and the full inspection cannot be realized. the

Utility model content

The technical problem solved by the utility model is to provide a multi-section lithium-ion battery protection board test fixture, which can detect one or more lithium-ion battery protection boards conveniently and quickly, so as to solve the problems in the above-mentioned background technology. Shortcomings. the

The technical problem solved by the utility model adopts the following technical solutions to realize:

The multi-cell lithium-ion battery protection board test fixture includes a workbench and a bracket, wherein the workbench is fixed on one side of the bracket, and a jig upper mold and a jig lower mold are arranged on it, and multiple sets of PCBs protrude Test pin; the top of the bracket is provided with a handle, one end of the handle is fixed on the workbench through a pin shaft, the middle position is connected to the lifting rod through a pin support, and the end of the lifting rod is fixedly connected to the upper mold of the jig through a fixing block. Drive the upper mold of the jig to move in the vertical direction together. In addition, the lower mold of the jig is fixed on the workbench. The upper mold of the jig is provided with a number of holes with a diameter of 1.70±0.05mm and a distance of 2.4±0.1mm. The array hole, the PCB test pin matches the aperture of the array hole, and can be directly inserted into and removed from the array hole.

In the utility model, the number of PCB test pins in the upper mold of the multi-cell lithium-ion battery protection board test fixture can be increased and the positions can be changed to realize fast and accurate measurement of protection boards with different numbers, shapes and sizes. . the

In the utility model, the fixed block is connected with the upper mold of the jig through a threaded connector. the

Beneficial effects: the utility model can realize the measurement and positioning of multiple sections, different shapes, and different types of battery protection plates. When measuring different numbers of sections, different shapes, and different types of protective plates each time, it is only necessary to change the number of test pins on the jig and the arrangement of the test pins, and fix the protective plate on the jig. Thereby avoiding complicated wiring for each detection, and improving detection efficiency and accuracy. the
