[0022] Refer to the attached Figure 1 -Attached Figure 4 A tensioning device for diaphragm detection includes a mounting frame 400, a tensioning roller group 300 for limiting the position of a battery diaphragm 100 is installed inside the mounting frame 400, the tensioning roller group 300 includes a tensioning roller 1 310 and a tensioning roller 2 320 located on the bottom plane and a tensioning roller 3 330 located on the top plane, the horizontal projection surface of the tensioning roller 3 330 is located between the tensioning roller 1 310 and the tensioning roller 2 320, preferably the horizontal projection surface of the tensioning roller 3 330 is located in the middle of the tensioning roller 1 310 and the tensioning roller 2 320, wherein the battery diaphragm 100 passes through the bottom of the tensioning roller 1 310, the tensioning roller 3 320 in sequence, and the tensioning roller 3 330 passes through the bottom of the tensioning roller 1 310, the tensioning roller 3 320 ... The battery diaphragm 100 is directed to move in a bent posture at the top of the tensioning roller 30 and the bottom of the tensioning roller 320. The inner wall of the mounting frame 400 is also installed with an adjusting device 420 for controlling the distance between the tensioning roller 1 310 and the tensioning roller 2 320. The distance between the tensioning roller 1 310 and the tensioning roller 2 320 is adjusted by the adjusting device 420, thereby adjusting the moving path of the battery diaphragm 100. After adjusting the moving path of the battery diaphragm 100, the battery diaphragm passes through the tensioning roller group 300 in a tensioned posture, ensuring that the battery diaphragm can complete multiple inspections in a smaller space, thereby meeting the requirements of efficient inspection of surface defects of the battery diaphragm 100.

[0023] In summary, through the above-mentioned structural design, the tensioning and conveying posture of the battery separator 100 can be changed, so that the battery separator 100 can be transported and tested in a bent state, and the battery separator 100 can be tested differently in two directions in a smaller space, thereby meeting the needs of efficient testing of the battery separator 100 and improving the efficiency and accuracy of the testing of the battery separator 100.

[0024] It is preferred that the adjusting device 420 includes two symmetrically arranged groups, and the two groups of adjusting devices 420 respectively control the movement of tensioning roller 1 310 and tensioning roller 2 320. By setting up two groups of adjusting devices 420, the movement of tensioning roller 1 310 and tensioning roller 2 320 can be controlled individually to meet the demand for movement of tensioning roller 1 310 and tensioning roller 2 320; and the movement positions of tensioning roller 1 310 and tensioning roller 2 320 can be controlled to be different, thereby allowing the battery separator 100 to be in different postures for tensioning and conveying, thereby meeting the detection requirements under different conditions.

[0025] Specifically, the adjusting device 420 includes an adjusting screw rod 421 and an electric control device 423 for controlling the rotation of the adjusting screw rod 421. A screw rod sleeve 422 is sleeved on the outer side of the adjusting screw rod 421. The screw rod sleeve 422 is rotatably connected to the corresponding tensioning roller. During the rotation of the adjusting screw rod 421, the screw rod sleeve 422 can be driven to move linearly. The screw rod sleeve 422 slides with the inner wall of the mounting frame 400 to ensure the stability of the movement of the tensioning roller. Linear adjustment and conveying are performed by cooperating with the screw rod sleeve 422 and the adjusting screw rod 421, which can ensure the accuracy of the tensioning roller conveying and the stability of the tensioning roller position after adjustment.

[0026] A mounting seat 331 is rotatably connected to the side wall of the tensioning roller three 330, and an elastic telescopic rod 332 is arranged on the upper end of the tensioning roller three 330. The position of the tensioning roller three 330 can be tensioned according to the elastic telescopic rod 332 to ensure that the tensioning roller three 330 tensions the battery diaphragm 100 at the top, so that the battery diaphragm 100 is always in a tensioned state to detect the diaphragm surface.

[0027] The battery separator 100 moves linearly along a V-shaped path. A detection device 600 is provided on the inner side of the battery separator 100, and a light-emitting device 200 is provided on the outer side of the battery separator 100. The light-emitting device 200 can emit different types of light signals from the outer side toward the inner side. The detection device 600 takes an image of the surface of the battery separator 100 and sends it to the cloud for comparison to determine whether there are defects on the surface of the battery separator.

[0028] The detection device 600 is set to be multiple, and also includes a driving device 500 for controlling the circular movement of the multiple detection devices 600. Through the above-mentioned structural design, the detection device 600 can move synchronously with the battery separator 100, and the driving direction and speed of the driving device 500 are controlled to be relatively consistent with the battery separator 100. The detection device 600 and the battery separator 100 move relatively synchronously, which improves the shooting time of the detection device 600, improves the accuracy of the detection of the battery separator 100 and the efficiency of the movement of the battery separator 100.

[0029] Specifically; the light-emitting device 200 includes a first light-emitting component 210 located on the first side and a second light-emitting component 220 located on the second side. The first light-emitting component 210 and the second light-emitting component 220 can be located on both sides to emit different light signals, and can emit light sources of different colors or adjust the angle and intensity of the light source to meet the detection requirements of the battery separator 100.
