Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to a device for testing the insulation performance of new energy lithium batteries. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become mainstream, and with the advancement of new energy development, their application in the new energy field is also rapidly expanding.

[0003] Traditional testing equipment often adopts a fixed single-station layout. The testing process requires discrete operations of "manual loading, static testing, and manual unloading," and these three stages cannot be carried out in parallel. For example, after the insulation resistance test of one battery is completed, it is necessary to wait for the unloading to be completed before the loading of the next battery can proceed, which shortens the effective operating time of the equipment and makes it difficult to adapt to the pace of high-volume production lines.

[0004] Therefore, it is necessary to provide a new testing device for the insulation performance of new energy lithium batteries to solve the above-mentioned technical problems. Utility Model Content

[0019] In the specific implementation process, such as Figure 3-6As shown, the clamping assembly includes a gear and rack transmission assembly, two guide rails 401, two slide plates 402, two clamping plates 403, and a battery platform 6.

The two clamping plates 403 are fixedly connected to the upper surfaces of the two slide plates 402, and are symmetrically arranged.

Then, the transmission motor 7 is started to drive the transmission motor shaft 701 to drive the transmission plate 702 to rotate. The transmission plate 702 pushes the multi-station rotary wheel 3 to rotate intermittently in the lever guide groove 302 through the transmission plate 703. The station rotation 3 drives several lithium battery bodies 5 to rotate intermittently through several clamping components. When one of the lithium battery bodies 5 reaches below the lifting and detection component, the telescopic cylinder 201 is activated to drive the lifting rod 203 to push the probe connecting plate 204 downward to move horizontally. The probe connecting plate 204 drives the positive and negative electrode detection probes 205 into the positive and negative electrode posts 501 of the battery to perform insulation detection. After one lithium battery body 5 is detected, it is driven by the intermittent rotation component to immediately perform the next lithium battery body 5 for detection. Through multi-station rotation detection, manual feeding, static detection and manual unloading operations can be carried out simultaneously and in parallel, which can more efficiently improve the effective operating time of the equipment and adapt to the rhythm of high-volume production lines.
