A worktable 11 is fixedly connected to the top of the support frame 1, and a sliding groove 12 is provided on the surface of the worktable 11. The detection mechanism 2 is provided at the top of the worktable 11. The testing mechanism 2 includes a push-pull assembly 21, a power assembly 22, an emitting assembly 23, a rotating assembly 24, a clamping assembly 25, an adjusting assembly 26, a conveying assembly 27, and a photosensitive assembly 28.

When the push-pull door 211 is closed, the limiting block 214 restricts the position. At the same time, the magnet installed on the inner side of the limiting block 214 can provide a certain attraction force to prevent the push-pull door 211 from sliding open by itself, so that debris falls into it and jams the gear. The setting of the push-pull door 211 facilitates the installation and maintenance of the power assembly 22.

[0020] Please refer to the instruction manual appendix. Figure 2 and Figure 3As shown, in a preferred embodiment of the present invention, the power assembly 22 includes a motor 221, a drive gear 222, and a driven gear 223. The motor 221 passes through the support frame 1 and is fixedly connected to the drive gear 222. The driven gear 223 meshes with the outer side of the drive gear 222. The motor 221 drives the drive gear 222 to rotate, and the drive gear 222 drives the driven gear 223 to rotate. The two gears can be set to adjust their transmission ratio so that the rotation speed of the rotating assembly 24 matches the speed of the conveyor belt 271, so that the clamping assembly 25 can smoothly clamp the battery core on the conveyor belt 271.

[0021] Please refer to the instruction manual appendix. Figure 6 and Figure 7 As shown, in a preferred embodiment of the present invention, the emitting component 23 includes a fixed column 231 and a laser emitter 232. The fixed column 231 is fixedly connected to the support frame 1. The laser emitter 232 is fixedly connected to the top of the fixed column 231. The laser emitter 232 is a laser infrared light source. Its light emission principle is: using stimulated emission generated after the laser medium is excited, infrared light is output. The laser has extremely high luminous efficiency and luminous intensity. The photoelectric conversion efficiency of semiconductor laser can reach up to 80%, which can greatly reduce energy consumption. Moreover, it has a large illumination distance and stable performance.

[0022] Please refer to the instruction manual appendix. Figure 7 As shown, in a preferred embodiment of the present invention, the rotating assembly 24 includes a rotating cylinder 241 and a mounting plate 242. The rotating cylinder 241 is fixedly connected to the driven gear 223. The mounting plate 242 is evenly arranged on the outer side of the top end of the rotating cylinder 241. A bearing is provided between the driven gear 223 and the fixed column 231. The driven gear 223 drives the rotating cylinder 241 to rotate, which in turn drives the mounting plate 242 to rotate.

[0023] Please refer to the instruction manual appendix. Figure 7 and Figure 8 As shown, in a preferred embodiment of the present invention, the clamping assembly 25 includes a cylinder 251, a connector 252, a connecting rod 253, a clamping claw 254, and a fixing block 255. The top end of the mounting plate 242 is fixedly connected to the cylinder 251, the connector 252 is fixedly connected to one side of the cylinder 251, the top end of the connector 252 is rotatably connected to the connecting rod 253, and the clamping claw 254 is rotatably connected to one side of the connecting rod 253. The fixing block 255 is provided on the outer side of the clamping claw 254, and the inner side of the fixing block 255 is provided with symmetrical inclined grooves. The clamping claw 254 and the fixing block 255 are in a sliding relationship. When the piston rod in the cylinder 251 moves inward, the connecting rod 253 is connected by the connector 252, causing the connecting rod 253 to move along the inclined grooves on the inner side of the fixing block 255, thereby causing the clamping claws 254 to move closer to each other and clamp the battery core. Buffer cotton is provided on the inner side of the clamping claws 254 to prevent the battery core from being damaged by the clamping claws 254.

[0024] Please refer to the instruction manual appendix. Figure 7 and Figure 9 As shown, in a preferred embodiment of the present invention, the adjustment assembly 26 includes an adjustment plate 261, an adjustment block 262, a screw 263, and a beam splitter 264. The adjustment plate 261 is disposed on one side of the cylinder 251. The adjustment block 262 is slidably connected to the inner side of the adjustment plate 261. The screw 263 is threadedly connected to the inner side of the adjustment block 262. The beam splitter 264 is fixedly connected to the top of the adjustment block 262. The beam splitter 264 operates on the principle of light refraction and reflection; when a beam of light passes through the surface of a transparent medium, it is refracted. If the surface of the medium is oblique, the light will be deflected during refraction, and the light will be split into two beams in two directions. The angle of deflection depends on the angle of incidence of the light and the refractive index of the medium. The beam splitter 264 splits the light emitted by the laser emitter 232 into two beams. By rotating the screw 263 to adjust the position of the beam splitter 264, the angle between the two beams can be changed. When the standard of the battery core to be inspected changes, the inspection light can be adjusted by adjusting the screw 263. It can be applied to the inspection of battery cores of different diameters.

[0025] Please refer to the instruction manual appendix. Figure 4 As shown, in a preferred embodiment of the present invention, the conveying assembly 27 includes a conveyor belt 271, a conveyor roller 272, a conveyor motor 273, a guide fixing block 274, a guide rod 275, and a collecting component 276. Conveyor belts 271 are provided on both sides of the rotating drum 241. A conveyor roller 272 is provided on the inner side of the conveyor belt 271. A conveyor motor 273 is fixedly connected to one side of the conveyor roller 272. A guide fixing block 274 is installed on the outer side of the conveyor belt 271. A guide rod 275 is fixedly connected to the inner side of the top of the guide fixing block 274. The collecting component 276 is located at the rear end of the workbench 11. The collecting component 276 includes... The system includes a buffer plate 2761 and a waste parts bin 2762. The buffer plate 2761 is fixedly connected to the rear end of the workbench 11. The waste parts bin 2762 is installed on one side of the buffer plate 2761. The conveyor motor 273 drives the conveyor roller 272 to rotate, thereby causing the conveyor belt 271 to move. The guide rod 275 limits the battery core, keeping it in the middle position of the conveyor belt 271. After inspection, the unqualified battery core is released by the clamping claw 254 and falls onto the buffer plate 2761, then slides into the waste parts bin 2762 for unified processing. Qualified products will be sent to the conveyor belt 271 on the other side.

[0026] Please refer to the instruction manual appendix. Figure 4As shown, in a preferred embodiment of the present invention, the photosensitive component 28 includes a photosensitive bracket 281 and a photosensitive plate 282. The photosensitive bracket 281 is provided on the other side of the buffer plate 2761, and the photosensitive plate 282 is fixedly connected to the inner side of the photosensitive bracket 281. After the equipment is debugged, the battery core reaches the fixed position and the light source starts to output. If the photosensitive plate 282 senses the light signal after the light source outputs, the battery core passes through. If no light signal is sensed, the clamping claw 254 is released, and the battery core falls onto the buffer plate 2761 and then slides into the waste bin 2762 for unified processing.

[0027] Working principle: First, the battery core moves with the conveyor belt 271. The guide rod 275 limits the movement of the battery core, keeping it in the middle position of the conveyor belt 271. Second, when the piston rod in the cylinder 251 moves inward, it connects with the connecting piece 252, causing the connecting rod 253 to move along the inclined groove on the inner side of the fixing block 255. This causes the clamping claws 254 to come closer together, clamping the battery core. Three cores are arranged in a group. Third, the rotating assembly 24 rotates the battery core to the detection position. Laser emitter 232 emits light, and beam splitter 264 splits the light emitted by laser emitter 232 into two beams. When the screw 263 is rotated to adjust the position of beam splitter 264, the angle between the two beams can be changed. If the photosensitive plate 282 senses the light signal after the light source outputs, the cell passes through. If no light signal is sensed, the gripper 254 is released, and the cell falls onto buffer plate 2761, then slides into waste bin 2762 to await unified processing. Qualified products will be sent to conveyor belt 271 on the other side.
