Description

Technical Field

[0001] This utility model belongs to the field of battery assembly technology, specifically relating to a tooling for quickly checking the polarity correctness of a single cell assembly for zinc-silver batteries. Background Technology

[0002] Zinc-silver battery packs consist of several zinc-silver individual cells connected in series and parallel. The positive and negative terminals of each cell are distinguished by red and blue paint markings. After the individual cells are installed in the casing, to prevent incorrect installation, the correctness of the cell's assembly position must be checked according to the red and blue paint markings on the terminals. After assembly, each battery must be checked against the technical documents to verify the correctness of the positive and negative terminals. Due to the large number of batteries, the inspection is time-consuming and inefficient.

[0003] Currently, the method for checking polarity correctness involves verifying each battery individually against the markings in the technical documents after the individual cells are installed in the casing to ensure correct assembly. Chinese utility model patent CN212379534U discloses a fixture for checking the polarity of battery electrode groups. It uses an inspection plate with alignment and verification areas. The inspection holes in the verification area are aligned with the same-polarity electrodes on the polarity busbar. The correctness of the battery polarity is determined by observing the color markings on the busbar. However, this method cannot perform simultaneous testing of both the positive and negative electrodes with a single fixture. Utility Model Content

[0004] To address the aforementioned issues, this invention aims to provide a tooling for quickly checking the polarity of individual zinc-silver battery cells during assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tooling for quick inspection of the polarity correctness of a single cell assembly for zinc-silver batteries, comprising a flat plate body, on which a plurality of detection holes are provided, the positions of which correspond to the positive or negative terminals of the product.

[0006] Preferably, the flat panel body is made of easily cut materials, including but not limited to cardboard and laminate.

[0007] Preferably, the size of the detection hole is determined based on the diameter of the positive and negative terminals of the individual electrode, and the diameter of the hole is greater than the diameter of the positive and negative terminals and less than the distance between adjacent positive and negative terminals.

[0008] Preferably, the plate body is divided into a front and a back, with the distribution of the front detection holes corresponding one-to-one with the positive terminal of the product, and the distribution of the back detection holes corresponding one-to-one with the negative terminal of the product.

[0009] Preferably, the detection hole is a through hole.

[0010] Compared with the prior art, this utility model has the following advantages: This tooling is low-cost and easy to promote, with extremely low material costs and simple manufacturing. It can be drilled according to the distribution of positive or negative electrodes, and is easy to operate. The positive electrode can be detected from the front, and after flipping it over, the detection holes are symmetrical with the front and correspond one-to-one with the distribution of negative electrodes, so the negative electrode can be detected. It can be quickly inspected, with short inspection time and high work efficiency. Attached Figure Description
