[0002] In the current battery manufacturing field, the battery cell is the core component of the battery, and the precise control of its thickness is crucial to the performance, safety and service life of the battery. With the continuous development of battery technology and the intensification of market competition, higher accuracy and efficiency requirements are put forward for the measurement and adjustment of battery cell thickness. At present, when measuring the thickness of the battery cell, the corresponding thickness measuring equipment is usually used. There are many types of thickness measuring equipment on the market, and most of the thickness measuring equipment uses contact to complete the measurement operation.

[0003] When using the battery thickness measuring equipment on the market, since it uses the contact lighting method for measurement, the position of the upper and lower contact pieces on it is fixed. During the specific operation, the staff places the battery between the upper and lower contact pieces and completes the measurement operation according to whether the external light is lit. However, this type of operation can only measure batteries of constant size, and cannot adjust the position to measure batteries of different sizes, which will limit its scope of use and bring inconvenience to users. In view of this, we proposed a high-precision battery thickness measurement and adjustment device. Utility Model Content

[0015] 2. The utility model can adjust the height of the electric push rod by using the servo motor provided, and can use the electric push rod with a fixed telescopic length to perform detection operations on battery cells of different sizes, thereby achieving the effect of being able to measure battery cells of various sizes.

When the first conductive sheet 14 and the second conductive sheet 351 are against the positive and negative poles of the battery cell, the LED lamp 11 is lit, and the battery cell thickness measurement operation is realized.

[0026] In this embodiment, fixing plates 15 are fixedly mounted on both ends of the lower guide block 12 , and the fixing plates 15 are fixedly mounted on the upper surface of the base plate 1 by a plurality of fastening screws, so as to facilitate the loading and unloading operations.

[0027] Specifically, a slide groove 20 is provided in the guide rail 2 along the height direction of the guide rail 2, and the slider 32 is located in the slide groove 20 and is slidably connected with the slide groove 20. The cross-sections of the slider 32 and the slide groove 20 are both T-shaped, and the size of the slider 32 is adapted to the size of the slide groove 20, so that the slider 32 can slide more smoothly.

[0028] Furthermore, the second conductive sheet 351 is located directly above the first conductive sheet 14 , and the guide hole 13 is used for the insertion operation of the battery cell.
