[0036] Working principle:

[0037] In actual use, the operator inserts one end of the lithium battery separator between the gaps of the two sets of installation rods 11 and between the gaps of the two sets of first belt conveyors 16 and the two sets of second belt conveyors 18, and then uses the control panel to make the second self-locking reversible motor 20 work. The output end of the second self-locking reversible motor 20 can drive the bidirectional screw lever 13 to rotate. Since the bidirectional screw lever 13 is threadedly connected with the two sets of second screw sleeve 14, the rotating bidirectional screw lever 13 can push the two sets of second screw sleeve 14 to move closer to or farther away from each other. When the gap length between the two sets of moving frame plates 15 reaches a suitable value, the control panel is used to synchronously extend the two sets of second electric telescopic rods 17 through the first synchronous controller. When the two sets of first belt conveyors 16 and the two sets of second belt conveyors 18 clamp the lithium battery separator, the control panel is used to make the two sets of first belt conveyors 16 and the two sets of second belt conveyors 18 work through the second synchronous controller. The conveying surfaces of the two sets of first belt conveyors 16 and the two sets of second belt conveyors 18 can push the lithium battery separator. At the same time, the control panel is used to extend the first electric telescopic rod 2. When the laser emitter 9 moves to a suitable height, the first self-locking reversible motor 10 is made to work. The output end of the first self-locking reversible motor 10 can drive the unidirectional screw lever 5 to rotate. Since the unidirectional screw lever 5 is threadedly connected with the first screw sleeve 6, the rotating unidirectional screw lever 5 can push the first screw sleeve 6 to move. When the first screw sleeve 6 moves the laser emitter 9 to the use position through the sleeve joint plate 7, the control panel is used to make the laser emitter 9 work. The laser emitted by the laser emitter 9 can form a plurality of precise micro-porous structures on the surface of the lithium battery separator. The moving frame plates 15 can conveniently change the punching position of the lithium battery separator, which brings convenience to the use of the lithium battery separator micro-porous structure laser precision forming device. At the same time, according to the above operation, one end of the lithium battery separator is inserted between the gaps of the two sets of installation rods 11 and between the gaps of the two sets of first belt conveyors 16 and the two sets of second belt conveyors 18. When the lithium battery separator is installed, the operator moves the two sets of installation rods 11 towards each other. When the upper and lower scraper plates 12 contact the upper and lower surfaces of the lithium battery separator, the four sets of connecting screw rods 22 are threadedly connected with the eight sets of connecting nuts 23. The operator rotates the eight sets of connecting nuts 23 clockwise and counterclockwise. When the eight sets of connecting nuts 23 tightly contact the two sets of positioning frame plates 21, the use positions of the two sets of installation rods 11 and the two sets of scraper plates 12 are fixed. At this time, when the lithium battery separator moves, the two sets of scraper plates 12 can scrape off the impurities adsorbed on the surface of the lithium battery separator. The installation rods 11 and the scraper plates 12 can clean the impurities adsorbed on the surface of the lithium battery separator, which improves the practicality of the lithium battery separator micro-porous structure laser precision forming device.
