[0002] In the production of batteries, in order to make the battery electrodes easy to form and prevent short circuits in the battery cells, adhesive tape is affixed to the front and back sides of the electrode ends in actual production. The existing electrode adhesive tape affixing mechanism usually adopts the method of manually applying and affixing adhesive tape, which is too slow.

[0040] The present invention provides a double-sided gluing module for a high-speed film making machine, comprising a frame 17 and two groups of electrode gluing mechanisms arranged on the frame 17 for performing electrode gluing operations. A material trough 18 is provided on the frame 17, and the material trough 18 is used to convey the electrode to be glued.

The guide slider 29 is slidably connected to the guide rail 30 installed on the frame 17. The adhesive paper raw material first passes around the feed roller 25 close to the adhesive paper tray 24, and then is alternately wound on the adhesive stripping roller 28 and the feed roller 25 away from the adhesive paper tray 24 to be transported to the adhesive pressing device 21 arranged at the paper output position of the discharge device 20. During the adhesive paper transportation process, the adhesive stripping cylinder 27 controls the adhesive stripping roller 28 to slide on the guide rail 30 through the drive shaft, thereby pulling out the adhesive paper on the adhesive paper tray 24.

[0042] Furthermore, the glue pressing device 21 is arranged at the paper output position of the discharge device 20 to receive the adhesive paper output by the feed roller 25. The glue pressing device 21 includes a support block 31 arranged below the adhesive paper and a clamping block 32 arranged above the adhesive paper to press it on the support block 31. The clamping block 32 is installed on a first positioning shaft 33, and the first positioning shaft 33 is installed on the frame 17. The end of the clamping block 32 is provided with a clamping cylinder 35 which is mutually transmission-connected with it. The clamping block 32 is driven by the clamping cylinder 35 to rotate along the axis of the first positioning shaft 33. The inner side of the head end of the clamping block 32 is provided with a clamping shaft 34 which presses the adhesive paper against the end of the support block 31.

[0043] Furthermore, the gluing device 22 is arranged on the side where the gluing device 21 discharges paper. The gluing device 22 includes a sliding assembly and a mounting plate 37. The sliding assembly is installed on the frame 17, and the mounting plate 37 is installed on the sliding assembly. Driven by the sliding assembly, the mounting plate 37 slides back and forth horizontally on the frame 17.

[0044] Furthermore, the lower paper clip assembly 38 includes a fixed sleeve 40, a lower glue paper clip 41 and a telescopic cylinder 42. The fixed sleeve 40 is installed on the mounting plate 37. The lower glue paper clip 41 can be telescopically inserted in front of the fixed sleeve 40. The telescopic cylinder 42 is arranged behind the fixed sleeve 40 and fixedly installed on the frame 17. The telescopic cylinder 42 is transmission-connected with the lower glue paper clip 41 so that the lower glue paper clip 41 can realize telescopic movement in the fixed sleeve 40. Secondly, the upper paper clip assembly 39 includes a clamping cylinder 43, a rotating shaft 4 and an upper glue paper clip 45. The clamping cylinder 43 and the second positioning shaft 44 are both installed on the mounting plate 37. The upper glue paper clip 45 is installed on the rotating shaft 4. The end of the upper glue paper clip 45 is transmission-connected with the clamping cylinder 43. Driven by the clamping cylinder 43, the upper glue paper clip 45 can rotate along the axis of the second positioning shaft 44.

[0045] Furthermore, when the adhesive paper is conveyed from the feeding device 20 to the gluing device 21, the adhesive paper is fed out from between the supporting block 31 and the pressing block 32. At this time, the sliding assembly is activated, causing the mounting plate 37 to move toward the gluing device 21. The lower adhesive paper clamp 41 is extended from the fixing sleeve 40 by the telescopic cylinder 42, so that the lower adhesive paper clamp 41 moves to the bottom of the adhesive paper. At the same time, the clamping cylinder 43 is activated, causing the upper adhesive paper clamp 45 to rotate toward the lower adhesive paper clamp 41 and abut against the lower adhesive paper clamp 41, thereby causing the upper adhesive paper clamp 45 to rotate toward the lower adhesive paper clamp 41 and abut against the lower adhesive paper clamp 41. The adhesive paper clamp 45 and the lower adhesive paper clamp 41 clamp the adhesive paper. After the adhesive paper is clamped, the sliding assembly drives the mounting plate 37 to move in the opposite direction, so that the upper adhesive paper clamp 45 and the lower adhesive paper clamp 41 are pulled out of the adhesive pressing device 21 to an appropriate length. When the adhesive paper is pulled out to an appropriate length, the pressing block 32 on the adhesive pressing device 21 presses the adhesive paper on the support block 31 for positioning under the drive of the pressing cylinder 35. At this time, the adhesive cutting device 23 descends, and the adhesive paper is cut by the cutter at the bottom of the adhesive cutting device 23, completing the material removal of the adhesive paper.

[0046] Furthermore, the upper glue paper clip 45 and the lower glue paper clip 41 are transported to the flipping device 1 located below it under the drive of the sliding component. The flipping device 1 includes a fixed frame 3 and a rotating shaft 4. The rotating shaft 4 is inserted in the fixed frame 3. The rotating shaft 4 is a hollow tube body, and the ports at both ends are set as vacuum inlets. The rotating shaft 4 is respectively connected to the vacuum device for vacuuming and the driving component 5 for driving it to rotate. The upper and lower sides of the fixed frame 3 are provided with card slots 10, and vacuum suction cups 6 are provided in the card slots 10. At least one spring 7 for resetting is provided between the two vacuum suction cups 6. The vacuum suction cup 6 is connected to the rotating shaft 4 through the tube body to achieve vacuum adsorption. A plurality of adsorption holes 12 are provided on the surface of the vacuum suction cup 6, and an arc-shaped positioning groove 13 is provided on the bottom surface.

[0047] Furthermore, after the glue clamping device 22 obtains the adhesive tape, the upper glue tape clamp 45 and the lower glue tape clamp 41 are driven by the sliding assembly to move the adhesive tape to the vacuum suction cup 6 located below it, and the vacuum suction cup 6 sucks the adhesive tape tightly by vacuum adsorption. At this time, the lower glue tape clamp 41 is retracted into the fixing sleeve 40 to a certain depth under the drive of the telescopic cylinder 42, so that the lower glue tape clamp 41 is separated from the adhesive tape, and the upper glue tape clamp 45 is swung upward under the drive of the pressing cylinder 35, thereby loosening the adhesive tape and fixing the adhesive tape on the vacuum suction cup 6. After the adhesive tape is sucked tightly by the vacuum suction cup 6, the sliding assembly drives the mounting plate 37 to move toward the glue pressing device 21 again to take the material. Since there is a certain gap between the lower glue tape clamp 41 and the vacuum suction cup 6, the gap is greater than the thickness of the adhesive tape, which prevents the lower glue tape clamp 41 from scraping or damaging the adhesive tape from the vacuum suction cup 6 during the resetting process.

[0048] Furthermore, after the adhesive tape is fixed on the vacuum suction cup 6, the driving component 5 drives the rotating shaft 4 to rotate by 0.5°, so that the rotating shaft 4 drives the fixing frame 3 to rotate by 0.5° synchronously, so that the vacuum suction cup 6 with the adhesive tape is synchronously flipped to the front and back sides of the pole piece in the material trough 18. The pressing device 2 includes a guide block 8 and a sliding arm 9 installed at the bottom of the guide block 8. The top sticking shaft 14 on the sliding arm 9 is clamped in the arc-shaped positioning groove 13 on the bottom surface of the vacuum suction cup 6. When the vacuum suction cup 6 with the adhesive tape is synchronously flipped to the front and back sides of the pole piece in the material trough 18, the top sticking shaft 14 descends, and the adhesive tape is The vacuum suction cup 6 of the paper is pressed against the electrode, so that the adhesive tape is synchronously attached to the front and back sides of the electrode. After the adhesive tape is attached, the sliding arm 9 rises, so that the top sticking shaft 14 is disengaged from the vacuum suction cup 6, and the depressed vacuum suction cup 6 is pulled back to the card slot 10 of the fixing frame 3 by the action of the spring 7 to achieve reset. At the same time, the vacuum suction cup 6 on the other side of the fixing frame 3 synchronously completes the above-mentioned adhesive tape adsorption operation, and the fixing frame 3 is driven by the rotating shaft 4 to rotate again by °, so that the vacuum suction cup 6 on the side filled with adhesive tape is flipped over to the front and back sides of the electrode again, realizing a cyclic adhesive tape attaching operation.

[0049] Furthermore, when the optical fiber sensor at the trough 18 detects that the pole piece is offset during the conveying process, the adjustment component at the bottom of the rack 17 drives the rack 17 to adjust its position. Specifically, the correction motor on the base is started, causing the adjustment block installed on the correction motor to undergo correction displacement. The adjustment block and the rack 17 are fixedly connected to each other, so that the rack 17 can achieve synchronous displacement with the adjustment block to complete the correction. The above is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Technicians in this industry can make some deformations and modifications under the inspiration of this technical solution. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
