[0002] The battery cell shell of a new energy vehicle refers to the outer shell used for encapsulating and protecting battery monomers, which is made into a rectangular shell by processes such as stamping and welding using aluminum alloy plates. After the production of the battery cell shell, in order to ensure that the material uniformity meets the design requirements and there are no defects on the surface of the battery cell shell, eddy current detection is usually used to detect and evaluate the end face of the battery cell in actual applications. Due to the differences in the body layout and design of new energy vehicles, different modular designs will result in differences in the specifications of the battery cell shells. It is necessary to design a detection device whose position of the eddy current detection probe can be adjusted as needed to improve the detection uniformity and coverage. Secondly, with the rapid development of the new energy vehicle industry, the production scale of battery cell shells is continuously expanding. Some traditional detection methods are slow and cannot meet the real-time detection requirements on large-scale production lines. Although the production workshop is relatively clean, a certain amount of dust or other small particles may still adhere to the end face of the battery cell shell, which will affect the evaluation of the conductivity and defects of the material in eddy current detection.

[0020] By adopting the above technical solution, the electric fixture 8 reciprocates under the guidance of the chute 606.

[0030] By adopting the above technical solution, the rebound switch 608 is squeezed by the trigger plate 607 during the rising process of the guide plate 604, and the rebound switch 608 controls the opening and closing of the fan 9.
[0031] Two symmetrically distributed support shafts 707 are fixedly provided on the outer wall of the mounting plate 601, and synchronous wheels 708 are rotatably sleeved on the outer walls of the two support shafts 707. A synchronous shaft 710 is rotatably provided between the workbench 2 and the bracket 1 on the side close to the screw 702, and the synchronous shaft 710 is connected to the screw 702 through a synchronous toothed belt transmission group. The outer wall of the synchronous shaft 710 is sleeved with synchronous wheels 708, and the outer walls of the three synchronous wheels 708 are sleeved with synchronous belts 709, and the driving end of the screw-type linear electric cylinder 609 is fixedly connected to the synchronous belt 709.
[0032] By adopting the above technical solution, the synchronous shaft 710 is driven to rotate by the synchronous wheel 708 during the movement of the synchronous wheel 708 .
[0033] Working principle: First, the processed battery cell shell is transported to the electric clamp 8 in sequence through an external transport device, such as Figure 7 , Figure 9 and Figure 10As shown, after the electric clamp 8 clamps and fixes both sides of the battery cell housing, the screw - type linear electric cylinder 609 is controlled to start. The screw - type linear electric cylinder 609 drives the moving plate 603 to move laterally towards the pushing component 7 under the guidance of the guide rail 602 through the fixed column 610. During the movement of the moving plate 603, the guide plate 604 and the electric clamp 8 are driven to move under the guidance of the chute 606 through the guide rod 605. During this process, the trigger plate 607 rises to squeeze the rebound switch 608, and the rebound switch 608 is pressed to turn on the blower 9. The two air ducts of the blower 9 apply air flow to the battery cell housing simultaneously from the top and the bottom to remove the dust residues at both ends of the battery cell housing. After the electric clamp 8 moves to the outermost end, it stops clamping the battery cell housing. During this process, the screw - type linear electric cylinder 609 drives the synchronous shaft 710 to rotate forward through the synchronous belt 709 and the synchronous pulley 708. The synchronous shaft 710 drives the screw 702 to rotate forward through the synchronous toothed - belt transmission group, so that the moving block 703 drives the push rod 704 to move to the mounting plate 601 under the guidance of the base plate 706. According to the above - mentioned same steps, the screw - type linear electric cylinder 609 is controlled to drive the electric clamp 8 to move to the initial position. During this process, the synchronous belt 709 and the synchronous pulley 708 drive the screw 702 to rotate reversely, and the battery cell housing is pushed by the push rod 704 and the push plate 705 to pass through the two groups of eddy - current detection probes 10 under the guidance of the first follower wheel 409 and the second follower wheel 411. By operating in this way repeatedly, the detection of the battery cell housing is realized; When detecting battery cell housings of different specifications, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the control two lifting electric cylinders 412 drive the contraction of the corresponding designed distance at the driving ends, so that the sliding detection frame 401 moves upward. During this process, the two side frames 407 are driven to move upward and move a certain distance away from the sliding detection frame 401 at the same time through the four connecting rods 408. The upward movement distance of the two side frames 407 is half of the upward movement distance of the sliding detection frame 401, so that the two side frames 407 are always located at the central position between the sliding detection frame 401 and the fixed detection frame 402. The first sliding plate 405 on one side of the connecting plate 511 drives the driving shaft 508 to rotate through the rack 513 and the rotating gear 514 during the movement. During the upward movement of the sliding detection frame 401, the sliding shaft 509 is driven to rise synchronously through the connecting plate 511. The driving shaft 508 drives the sliding shaft 509 to rotate synchronously, and the two corresponding lifting rods 512 are driven to move away from each other under the guidance of the bottom plate 515 and the connecting plate 511 through the two reverse thread grooves 510. The two lifting rods 512 drive the corresponding lifting plates 505 to move away from each other, and drive the upper and lower two groups of eddy - current detection probes 10 to move equidistantly and expand under the action of the guide groove 506 and the lateral moving slider 502 to increase the detection coverage area. Similarly, when the sliding detection frame 401 descends and resets, the upper and lower two groups of eddy - current detection probes 10 contract equidistantly.
