[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention uses a clamping rod to clamp the end of the copper foil against the outside of the take-up drum when the copper foil is cut and rolled up. The take-up motor is powered on and started, and the positioning tube and the take-up shaft are driven to rotate through the take-up gear and the rotating gear. When the take-up shaft rotates, the take-up drum is driven to rotate, and the copper foil is rolled up through the take-up drum and the clamping rod that clamps the copper foil. After the copper foil rolled up on the outside of the take-up drum reaches a certain thickness, the rotating drum is rotated counterclockwise to interchange the positions of the two take-up drums, and the copper foil between the two take-up drums is cut off. The copper foil is continued to be rolled up by the second take-up drum, and the copper foil is rolled up by switching different take-up drums. Then, the take-up drum that has rolled up the copper foil is removed and replaced. During the operation, there is no need to interrupt the operation of the cutting equipment, thereby avoiding unnecessary time waste and improving the working efficiency of the copper foil cutting.

[0018] 2. The present invention overlaps the end of the cut copper foil on the outside of one of the reel drums, energizes the adsorption electromagnet and the clamping electromagnet and attracts each other magnetically, and the adsorption electromagnet drives the clamping plate to slide inside the installation groove and compresses the reset spring. At this time, the clamping rod moves toward the reel drum and presses the end of the copper foil on the outside of the reel drum, ensuring that the reel motor drives the positioning tube and the reel shaft to rotate through the reel gear and the rotating gear, so that the reel drum rotates, and the rotating reel completes the reeling action of the copper foil through the clamping rod that presses the copper foil;

[0019] 3. After the positions of the two take-up drums are rotated and switched, and the copper foil between the two take-up drums is cut off, the take-up shaft in the middle of the take-up drum that has finished winding up the copper foil is slid out, and the clamping rod is pulled out to the outside of the rotational positioning end block, so that the end of the clamping rod is separated from the copper foil and the take-up drum. The take-up drum that has wound up the copper foil can be replaced, and the new take-up drum can be installed, which is convenient for taking up the copper foil after winding up and replacing and installing the take-up drum.

A winding shaft 512 is inserted through the middle of the winding cylinder 508, and the end of the winding shaft 512 passes through the rotating positioning end block 505 and the positioning tube 514, so that the end of the copper foil after the shearing is overlapped on the outside of the winding cylinder 508, and the rotating gear 511, the winding gear 510 and the positioning tube 514 are driven to rotate by the winding motor 509, so that the two positioning tubes 514 drive the rotating positioning end block 505 and the winding cylinder 508 to rotate at the same time through the winding shaft 512, so as to wind up the copper foil after the shearing.

The winding shaft 512 is slidably pulled out from the rotary positioning end block 505, the winding drum 508 and the positioning tube 514, so that the winding drum 508 can be removed from between the two winding drums 508, thereby realizing the replacement of the winding drum 508.

[0033] like Figures 4 to 7As shown, a guide groove 506 is provided on the outer side of the rotation positioning end block 505, and a mounting groove 507 is opened on the inner side of the guide groove 506. A shearing press 6 is installed on the inner sides of the guide groove 506 and the mounting groove 507. The shearing press 6 includes a clamping plate 602, and the clamping plate 602 is slidably engaged with the inner side of the mounting groove 507. One end of the clamping plate 602 extends out of the mounting groove 507 and enters the inner side of the guide groove 506. A clamping rod 601 is slidably installed on the end of the clamping plate 602 located in the guide groove 506. The clamping rod 601 is used to clamp the copper foil overlapped on the outer side of the winding drum 508 to ensure that the winding drum 508 can wind up the copper foil when rotating.

[0034] A sliding groove is provided at the end where the clamping plate 602 is connected to the clamping rod 601, and one side edge of the clamping rod 601 is slidably engaged in the sliding groove. After the winding drum 508 completes the winding operation of the copper foil, the clamping rod 601 is slid and taken out from between the copper foil and the winding drum 508 without damaging the structure of the copper foil and affecting the removal of the winding drum 508.

[0035] An adsorption electromagnet 605 is fixedly embedded on the surface of the clamping plate 602 facing the center of the rotation positioning end block 505, a return spring 603 is provided between the adsorption electromagnet 605 and the rotation positioning end block 505, a clamping electromagnet 604 is provided on the outside of the return spring 603, the clamping electromagnet 604 is fixed to one end surface of the mounting groove 507, the adsorption electromagnet 605 and the clamping electromagnet 604 are magnetically adsorbed and connected after power is turned on, the magnetic adsorption force between the adsorption electromagnet 605 and the clamping electromagnet 604 is greater than the elastic force of the adsorption electromagnet 605, the magnetic adsorption between the clamping electromagnet 604 and the adsorption electromagnet 605 is utilized to control the movement of the clamping plate 602 and the clamping rod 601, so as to realize the clamping of the copper foil on the outside of the winding drum 508 by the clamping rod 601.

[0036] Working principle: First, turn on the power of the device, cut the copper foil by the cutting tool 7, and overlap the end of the cut copper foil on the outside of one of the reel drums 508, and the adsorption electromagnet 605 and the clamping electromagnet 604 are energized and magnetically attracted to each other. The adsorption electromagnet 605 drives the clamping plate 602 to slide inside the installation groove 507 and compress the reset spring 603. At this time, the pressing rod 601 moves toward the reel drum 508 and presses the end of the copper foil on the reel drum 508. 08, the reeling motor 509 is powered on and started, and drives the positioning tube 514 and the reeling shaft 512 to rotate through the reeling gear 510 and the rotating gear 511. When the reeling shaft 512 rotates, it drives the reeling drum 508 to rotate, and the copper foil is reeled through the reeling drum 508 and the pressing rod 601 that presses the copper foil. After the copper foil reeled outside the reeling drum 508 reaches a specified thickness, the staff rotates the rotating drum 503 counterclockwise to rotate the reeling drum 508 in one direction;

[0037] The copper foil contacts with another take-up drum 508, and the end of the take-up drum 508 rotates to position the adsorption electromagnet 605 and the clamping electromagnet 604 inside the end block 505, which are energized at the same time. The adsorption electromagnet 605 drives the clamping plate 602 to slide inside the mounting groove 507 and compress the return spring 603. At this time, the clamping rod 601 moves toward the take-up drum 508 and presses the end of the copper foil against the outside of the take-up drum 508. At the same time, the staff cuts the copper foil between the two take-up drums 508. As soon as the copper foil between the two take-up drums 508 is cut, the take-up motor 509 close to the end of the second take-up drum 508 is energized and started. It is electrically started and drives the positioning tube 514 and the winding shaft 512 to rotate through the winding gear 510 and the rotating gear 511. When the winding shaft 512 rotates, it drives the winding drum 508 to rotate, and the copper foil is wound through the winding drum 508 and the clamping rod 601 that clamps the copper foil. After the copper foil wound on the outside of the winding drum 508 reaches a certain thickness, the above operation is repeated to ensure that when the copper foil is sheared and rolled up, the copper foil is rolled up by switching different winding drums 508, and then the winding drum 508 that has rolled up the copper foil is removed and replaced. There is no need to interrupt the operation of the shearing equipment during the operation, which avoids unnecessary waste of time and improves the work efficiency of copper foil shearing.
