[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see the appendix Figure 1 Appendix Figure 8 and attached Figure 9 This invention provides a new energy lithium battery separator testing device, including a support column 1, a moving mechanism 2 between two support columns 1, a rotating mechanism 3 on the lower side of the moving mechanism 2, and a focusing mechanism 4 on the rear side of the rotating mechanism 3. The moving mechanism 2 includes a support plate 201, which is fixedly connected to the side wall of a support column 1. A rack 202 is fixedly connected to the front and rear sides of the top wall of the support plate 201. Moving blocks 203 are slidably connected to both sides inside the support plate 201. A connecting shell 208 is provided on the lower side of the moving block 203. A detector 209 is provided on the front side of the connecting shell 208. A drive motor 204 is fixedly connected to the top wall of the moving block 203. The output end of the drive motor 204 passes through the inner wall of the moving block 203 and is fixedly connected to a worm gear 206. A worm wheel 207 is meshed on one side of the worm gear 206. The front and rear ends of the worm wheel 207 pass through the moving block 203 and are fixedly connected to moving wheels 205. Multiple moving wheels 205 mesh with the rack 202.

[0022] By activating the drive motor 204 of the corresponding detector 209, the worm gear 206 connected to the output end can be rotated. When the worm gear 206 rotates, it can drive the meshing worm wheel 207 to rotate. The rotation of the worm wheel 207 can drive the moving wheel 205 connected to the front and rear sides to rotate, so that the moving wheel 205 will move along the rack 202. When the moving wheel 205 moves, it can drive the connected connecting rod 212 to move. Since the connecting rod 212 is engaged in the connecting housing 208, it can drive the connecting housing 208 to move accordingly. When the connecting housing 208 moves, it can drive the connected detector 209 to move, thereby achieving the effect of flexibly adjusting the position of the detector 209 according to different detection requirements. At the same time, the cooperation between the worm wheels 207 can achieve a self-locking effect, preventing the worm wheels 207 from driving the moving wheel 205 to continue moving after it has moved to the appropriate position.

[0023] Please see the appendix Figure 1 On the other side, the top wall of the support column 1 is rotatably connected to a rotating plate 211, which is located on one side of the support plate 201.

[0024] By rotating the rotating plate 211 downwards, the limiting effect on the moving block 203 and the connecting shell 208 can be removed. The support plate 201 has a notch on the side near the rotating plate 211, so the moving block 203 and its connecting parts can be disassembled or installed as needed through the inner wall of the support plate 201 and the notch. Then, the rotating plate 211 is rotated to reset it so that the support plate 201 is inserted into the rotating plate 211 for support, and bolts are screwed in for limiting and fixing. Thus, the number of moving blocks 203, connecting shells 208 and detectors 209 can be adjusted as needed.

[0025] Please see the appendix Figure 6 and attached Figure 8Both movable blocks 203 have connecting rods 212 fixedly connected to their bottom walls. Both connecting shells 208 have chambers 213 on their upper sides. The bottom ends of both connecting rods 212 penetrate into the chambers 213 and are fixedly connected to connecting plates 214. Springs 215 are fixedly connected to the front and rear sides of the top walls of both connecting plates 214. The top ends of multiple springs 215 are fixedly connected to the top walls inside the chambers 213.

[0026] When disassembling or installing the movable block 203, if the movable wheel 205 is stuck on the rack 202 and cannot slide directly, the operator can lift the movable block 203 upward to move the movable wheel 205 upward, thereby canceling the engagement between the movable wheel 205 and the rack 202. When the movable block 203 moves upward, it will also drive the connecting rod 212 upward. When the connecting rod 212 moves upward, it can drive the connecting plate 214 at the bottom to move upward and compress the spring 215. Therefore, after releasing the movable block 203, the movable wheel 205 can re-engage with the rack 202, and the spring 215 can ensure the stability of its engagement.

[0027] Please see the appendix Figure 8 Guide rods 216 penetrate the front and rear parts of the two connecting plates 214. The upper and lower ends of the multiple guide rods 216 are fixedly connected to the inner wall of the chamber 213, and multiple springs 215 are arranged on the outer periphery of the guide rods 216.

[0028] By providing a guide rod 216, the connecting plate 214 and the spring 215 can be limited, thereby ensuring the stability of the movement of the connecting plate 214 and preventing the spring 215 from bending under pressure.

[0029] Please see the appendix Figure 1 The two pillars 1 are rotatably connected to the lower part of their adjacent sides by a support shaft 210.

[0030] The support shaft 210 provides auxiliary support for the new energy lithium battery separator to be tested, ensuring normal transport of the separator and facilitating testing by the detector 209 on the upper side.

[0031] Please see the appendix Figure 4 Appendix Figure 5 and attached Figure 6The rotating mechanism 3 includes a second drive motor 301, which is fixedly connected to the side wall of one side support column 1. The output end of the second drive motor 301 passes through the side support column 1 and is fixedly connected to a rotating shaft 302. The rotating shaft 302 passes through the inner walls of two connecting shells 208 in sequence. A sliding limit rod 313 passes through the upper part of each of the two connecting shells 208. The two ends of the limit rod 313 are respectively set on the side walls of the two support columns 1. The rotating shaft 302 has symmetrical slots 303 on its outer periphery. Both sides of the rotating shaft 302 are connected to a retaining shaft through the slots 303. 305. Both retaining shafts 305 are rotatably connected to the inner wall of the connecting housing 208. A bevel gear 307 is fixedly connected to the outer periphery of the retaining shaft 305. A bevel gear 308 meshes with the lower side of the bevel gear 307. The bottom end of the bevel gear 308 penetrates the bottom wall of the connecting housing 208 and is provided with a pinion 309. A transmission gear 310 meshes with the front side of the pinion 309. A gear ring 311 meshes with the front side of the transmission gear 310. A mounting shaft 312 is fixedly connected to the inner wall of the gear ring 311. The mounting shaft 312 is located on the outer periphery of the detector 209.

[0032] By starting the drive motor 301, the output shaft 302 connected to the drive motor can be rotated. Since the outer circumference of the shaft 302 has a slot 303, and the inner side of the retaining shaft 305 engages in the slot 303, the rotation of the shaft 302 can drive the connected retaining shaft 305 to rotate via the slot 303. When the retaining shaft 305 rotates, it can drive the outer bevel gear 307 to rotate. When the bevel gear 307 rotates, it can drive the lower meshing bevel gear 308 to rotate. When the bevel gear 308 rotates, it can drive the bottom pinion 309 to rotate. When the pinion 309 rotates, it can drive the meshing transmission gear 310 to rotate. When the transmission gear 310 rotates, it can drive the meshing gear ring 311 to rotate. The gear ring 311 can drive the connected mounting shaft 312 to rotate. Since the dimensions of the gear ring 311, the transmission gear 310, and the pinion 309 decrease sequentially, when the pinion 309 rotates, the detector 209 connected to the inner side of the mounting shaft 312 can be adjusted to a certain rotation angle. Thus, when the diaphragm shifts during the detection process, multiple detectors 209 can be flexibly adjusted to rotate at a certain angle simultaneously, ensuring normal image capture and detection accuracy. Furthermore, since the rotating shaft 302 passes through the connecting shell 208 and the connecting shell 208 is also limited by the limiting rod 313, the connecting shell 208 can slide normally along the rotating shaft 302, thereby achieving the goal of adjusting the rotation angle of the detector 209 without affecting the position adjustment of the detector 209.

[0033] Please see the appendix Figure 3 and attached Figure 5 Both detectors 209 are fixedly connected to mounting rings 304 on their outer periphery, and both mounting rings 304 are located on the top wall of the mounting shaft 312.

[0034] By incorporating a mounting ring 304 and locking components such as bolts, when the detector 209 needs to be disassembled separately, the limiting effect on the mounting ring 304 can be removed by unscrewing multiple bolts. The detector 209 can then be pulled out and disassembled along with the mounting ring 304. When the detector 209 needs to be installed, it can be inserted into the mounting shaft 312, and the protrusions around the mounting ring 304 can be engaged and positioned with the slots on the mounting shaft 312. The bolts can then be screwed in to secure it, thus enabling the detector 209 to be installed, disassembled, and replaced separately.

[0035] Please see the appendix Figure 3 and attached Figure 5 Both ends of the two locking shafts 305 are fixedly connected to the linkage shafts 306, and one end of each linkage shaft 306 penetrates through the side wall of the connecting shell 208.

[0036] The linkage shaft 306 allows for adjustment of the rotation of the retaining shaft 305 inside the connecting housing 208. When the connecting housing 208 needs to be installed, the linkage shaft 306 can be rotated to adjust the retaining shaft 305 to correspond with the retaining groove 303 on the rotating shaft 302, so that the retaining shaft 305 can be inserted into the retaining groove 303, thereby facilitating the installation of the connecting housing 208 into the outer periphery of the rotating shaft 302.

[0037] Please see the appendix Figure 2 Appendix Figure 4 and attached Figure 7 The focusing mechanism 4 includes a drive shaft 407, which is fixedly connected to the bottom end of a bevel gear 308. A sliding groove 408 is symmetrically provided on the outer periphery of the drive shaft 407. The drive shaft 407 is connected to a drive shaft 409 via the sliding groove 408. Fixed plates 401 are fixedly connected to the upper and lower sides of the rear walls of the two connecting shells 208. A drive motor 402 is fixedly connected to the top wall of the upper fixed plate 401. The output ends of the two drive motors 402 pass through the upper fixed plate 401 and are fixedly connected to threaded rods 403. A movable plate 404 is threadedly connected to the outer periphery of the threaded rod 403. Side plates 405 are fixedly connected to both sides of the movable plate 404. A base plate 406 is fixedly connected to the bottom wall of multiple sets of side plates 405. The bottom ends of the two drive shafts 409 are both connected to the base plate 406 and fixedly connected to the pinion 309. The two base plates 406 are rotatably connected to the top of the drive gear 310 and the outer periphery of the mounting shaft 312.

[0038] By starting the drive motor 402, the threaded rod 403 can be rotated. When the threaded rod 403 rotates, it can drive the movable plate 404 connected to the outer periphery to move. Since the movable plate 404 is connected to the side plates 405 on both sides and the side plates 405 are limited by the connecting shell 208, the movable plate 404 is also limited and cannot rotate. Thus, the threaded rod 403 can drive the movable plate 404 to move up and down. When the movable plate 404 moves, it can drive the base plate 406 to move through the side plates 405. When the base plate 406 moves, it can drive the pinion 309 and the transmission gear 31. 0. The gear ring 311 and the mounting shaft 312 move, thereby flexibly adjusting the height of the corresponding detector 209 to meet the focusing requirements of different detections. When the base plate 406 moves, it also drives the engaged transmission shaft 2 409 to move along the slide groove 408 on the outer periphery of the transmission shaft 1 407. When the bevel gear 2 308 rotates, it drives the transmission shaft 1 407 to rotate. When the transmission shaft 1 407 rotates, it drives the engaged transmission shaft 2 409 to rotate. Thus, while adjusting the height of the detector 209, it does not affect the rotation of the pinion 309 driven by the bevel gear 2 308.

[0039] Please see the appendix Figure 8 Both sides of the two connecting shells 208 have a limiting groove 410 at the bottom, and the inner sides of multiple side plates 405 are slidably connected in the limiting groove 410.

[0040] By setting a limiting groove 410, the side plate 405 can be limited, thereby ensuring the stability of the movement of the side plate 405 and its connecting parts.

[0041] Working principle: In actual use, the new energy lithium battery separator to be tested is conveyed through the upper side of the support shaft 210. At this time, the detector 209 on the upper side can detect the passing separator. If the separator deviates by a certain angle during the detection process, the drive motor 301 is started to drive the rotating shaft 302 to rotate and the clamping shaft 305 to drive the bevel gear 307 to rotate. At this time, the bevel gear 308 can drive the connected pinion 309 to rotate. When the pinion 309 rotates, it can drive the mounting shaft 312 to rotate through the transmission gear 310 and the gear ring 311, so that the detector 209 can rotate by a certain angle according to the deviation of the separator, ensuring normal image capture and detection accuracy. Based on this, when the position of detector 209 needs to be adjusted, the drive motor 204 corresponding to detector 209 can be started to drive the worm 206 to rotate, which in turn drives the worm wheel 207 and the moving wheel 205 connected to the worm wheel 207 to rotate. This causes the moving wheel 205 to move along the rack 202. When the moving wheel 205 moves, it can drive the connected detector 209 to move through the moving block 203 and the connecting shell 208. This allows the position of detector 209 to be flexibly adjusted according to different detection requirements. When detector 209 moves to a suitable position, the drive motor 402 can be started to drive the threaded rod 403 to rotate and drive the connected moving plate 404 to move up and down. When the moving plate 404 moves, it can drive the base plate 406 to move through the side plate 405, which in turn drives the pinion 309, transmission gear 310, gear ring 311 and mounting shaft 312 to move. This allows the height of the corresponding detector 209 to be flexibly adjusted to meet the focusing requirements of different detections.
