[0029] The guide shaft 9 is provided with a side positioning device 10 and an end positioning device 11 , and the side positioning device 10 and the end positioning device 11 respectively regularly position the sides and both ends of the battery module.

[0030] In this patent, the detection device is a dual-station device, which greatly improves the efficiency of detection. At the same time, compared with manual testing, the automated testing equipment not only improves the testing efficiency, but also improves the testing accuracy.

[0032] Its working principle is: the tooling pallet is transported into the insulation and voltage resistance station by the double-speed chain. The insulation and voltage resistance station is a double-station. After the pallet is in place, the proximity switch senses the pallet, and then the lifting mechanism rises to lift the battery module 29, and the right RFID reads the information. After the information is read, it is transported into the station 1 or station 2 test station by a roller line. After the proximity switch senses that the pallet is in place, the lifting cylinder rises to lift and position the battery module, and the end positioning device 11 positions the battery module 29 in the length direction, and then the side positioning device 10 regularly positions the side of the battery module 29. After the module is positioned, the downward pressure detection device 4 is pressed down to make the probe 8 press the battery module, and the program controls the Kikusui tester to test the insulation and voltage resistance of the total positive electrode and the shell, the total negative electrode and the shell of the module. After the test is completed, the product is OK, the downward pressure cylinder, the end positioning cylinder and the side positioning cylinder are reset, and the product flows out of the station. If the product is NG, the tooling tray will be transported to the buffer by the NG conveyor line. When the buffer is full, an alarm will be given and the product will be taken off the line. This patent only protects the structural part of the detection device, and the electrical part is only used to illustrate the test process and principle of this patent and is not protected.

When the first lateral cylinder 13 and the second lateral cylinder 14 drive the first and second side plate positioning cylinders 15 and 16 to move to both ends, an avoidance space 19 is reserved for the battery module. The avoidance space 19 is only for the convenience of loading the battery module and preventing interference. Therefore, when a product comes in, the first and second lateral cylinders 13 and 14 drive the first side plate positioning cylinder 15 and the second side plate positioning cylinder 16 to move to both ends respectively. The first lateral cylinder 13 and the second lateral cylinder 14 are rodless cylinders. Figure 8 The middle is the working status diagram.
