Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, in particular to a punching device for new energy battery electrode sheets. Background Art

[0002] Lithium batteries are batteries that use lithium metal or lithium alloys as the positive and negative electrode materials and a non-aqueous electrolyte solution. They can be broadly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium batteries consist of positive and negative electrodes. The electrodes utilize conductive sheets, insulating sheets, a heating system, and external wiring. A temperature sensor is placed between the insulating and conductive sheets. The heating electrode sheet has a temperature control function and a heat dissipation mesh on the inside to effectively dissipate localized heat, making it more convenient, comfortable, and safer to use. During the electrode sheet processing process, a stamping device is used to stamp and shape it.

[0003] However, the existing electrode sheet stamping processing device requires manual unloading after stamping the electrode sheet, which is not conducive to improving the processing efficiency of the electrode sheet stamping.

[0004] In the prior art, a Chinese patent with publication number CN219378601U has been proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: an electrode sheet stamping device in the field of lithium battery processing technology is disclosed, including a stamping seat, a bracket is installed on the top of the stamping seat, a stamping machine is passed through the top of the bracket, a stamping groove is provided on the top of the stamping seat, and the stamping groove is connected to the stamping table by a welded support column. A connecting frame is installed on the front of the stamping seat, a cylinder is fixed on the top of the connecting frame, one end of the cylinder is fixedly connected to a movable seat by a telescopic rod, a shovel is welded on one end of the movable seat, a cleaning component is installed on the side of the movable seat, and a discharge port is provided on the front of the stamping groove. The utility model can push the stamped electrode sheet on the positioning ring to the discharge port by setting a shovel, and the shovel has a cleaning roller that moves synchronously with it. The rubber bristles connected to the cleaning roller are used to clean the stamping table. After stamping, there is no need to manually remove the workpiece, thereby improving the processing efficiency of the battery electrode sheet.

[0005] Although this prior art eliminates the need to manually remove the workpiece after stamping, thereby improving the processing efficiency of the battery pole piece, it is unable to polish the burrs on the edges of the battery pole piece, and requires subsequent separate polishing, which affects the overall processing efficiency.

[0029] The present invention is further described in detail below with reference to the embodiments: Example 1

[0030] like Figure 1-7 As shown, the utility model provides a stamping device for new energy battery electrode sheets, including a stamping assembly 1, a slide 2 and a grinding receiving frame 3.

[0031] The grinding assembly comprises a grinding disc 4, an annular groove provided on the top of the grinding disc 4 and a waste material suction cup 5 movably connected to the inner wall of the annular groove.

[0032] The positioning and pushing assembly includes a C-shaped linkage rod 14 and a linkage gear 16 with teeth meshing on the side surfaces of the two ends of the C-shaped linkage rod 14. The upper surface of the C-shaped linkage rod 14 is rotatably connected to the limiting wheel 10 through the mounting frame. A threaded rod 17 is fixedly connected to the center of the upper surface of the linkage gear 16. The outer wall of the top end of the threaded rod 17 is threadedly connected to the limiting resistance block 12. A suction cup mounting groove 18 is provided at the bottom of the grinding receiving frame 3, and the inner wall of the suction cup mounting groove 18 is movably connected to the vacuum suction cup 13.

[0033] The bottom surface of the limit block 12 is provided with a block threaded hole 20 for receiving the threaded rod 17, the inner wall of the block threaded hole 20 is threadedly connected to the outer wall of the threaded rod 17, and the bottom of the inner wall of the grinding receiving frame 3 is provided with a block mounting groove 19 for installing the limit block 12, and the outer wall of the limit block 12 is slidably connected to the inner wall of the block mounting groove 19.

[0034] A linkage gear 16 is provided on one side of the limit block 12, and a waste suction pipe 8 is fixedly connected to the upper surface of the waste suction cup 5. The circumference of the linkage gear 16 that the teeth can drive the rotation of the teeth is less than the distance that the limit wheel 10 moves toward the limit block 12. Example 2

[0035] like Figure 1-7 As shown, based on Example 1, the present invention provides a technical solution: preferably, the bottom end of the linkage gear 16 is rotatably connected to the inner wall of the grinding receiving frame 3 through a mounting plate, a limiting guide groove 11 is provided at the bottom of the inner wall of the grinding receiving frame 3, the inner wall of the limiting guide groove 11 is movably connected to the outer wall of the limiting wheel 10 near the bottom end, and the upper surface of the mounting plate is slidably connected to the bottom surface of the C-shaped linkage rod 14. A linkage hydraulic rod 15 located at the bottom of the grinding receiving frame 3 is fixedly connected at the center of one side of the C-shaped linkage rod 14, and a feeding hydraulic push rod 9 for pushing the electrode sheet is fixedly connected to the bottom of the inner wall of the grinding receiving frame 3.

[0036] The outer wall of the C-shaped linkage rod 14 is movably connected to the bottom surface of the grinding receiving frame 3 through a slidingly installed ring.

[0037] A grinding drive motor 6 is fixedly connected to the top center of the grinding disc 4, and a grinding hydraulic push rod 7 is fixedly connected to the outer wall of the grinding drive motor 6 through a casing. The bottom end of the vacuum suction cup 13 is fixedly connected to a suction cup hydraulic rod for pushing it.

[0038] The following is a detailed description of the working principle of the stamping device for new energy battery electrode sheets.

[0039] like Figure 1-7 As shown, after the electrode sheet is punched, it is transported to the grinding receiving frame 3 through the slide 2. At this time, the linkage hydraulic rod 15 is started, pushing the C-type linkage rod 14 to move toward its extended end. During the movement, the C-type linkage rod 14 will drive the limiting wheel 10 to slide on the inner wall of the limiting guide groove 11, and the outer wall of the limiting wheel 10 near the top will gradually come into contact with the electrode sheet. Since there are two groups of limiting wheels 10, the electrode sheet will be gradually pushed toward the position of the limiting block 12.

[0040] When the C-type linkage rod 14 is pushed, the C-type linkage rod 14 will simultaneously drive the linkage gear 16 to rotate through the teeth at both ends, and the rotation of the linkage gear 16 will drive the threaded rod 17 to rotate. During the rotation of the threaded rod 17, the threaded rod 17 will use the thread to push the limit block 12 to start sliding upward on the inner wall of the block mounting groove 19. When the limit block 12 moves up to the specified position and stops moving up, the C-type linkage rod 14 drives the limiting wheel 10 to push the electrode sheet gradually toward the linkage gear 16 on the limit block 12 until it fits with the inner wall of the linkage gear 16. At this time, the teeth at the end of the C-type linkage rod 14 are disengaged from the linkage gear 16, and the circumference of the rotation that can be driven by the teeth is less than the distance that the limiting wheel 10 moves toward the limit block 12.

[0041] When the electrode sheet fits the inner wall of the linkage gear 16, the vacuum suction cup 13 moves up under the push of the suction cup hydraulic rod, and the electrode sheet is adsorbed and fixed by the suction cup mounting groove 18, and then the linkage hydraulic rod 15 begins to reset. At this time, the linkage hydraulic rod 15 pulls the C-type linkage rod 14 to drive the limiting wheel 10 to reset and move. After the limiting wheel 10 moves back a certain distance, the teeth at the end of the C-type linkage rod 14 re-engage with the linkage gear 16 and drive the linkage gear 16 to rotate in the opposite direction. At this time, the linkage gear 16 drives the threaded rod 17 to reverse, and the limiting block 12 begins to gradually move downward under the action of the reversal of the threaded rod 17 until its surface is flush with the bottom of the inner wall of the grinding receiving frame 3. At this time, the limiting wheel 10 is coincidentally reset.

[0042] Then the grinding hydraulic push rod 7 is started to push the grinding disc 4 downward and start to rotate under the drive of the grinding drive motor 6 to grind the electrode sheet in a fixed state. During the grinding process, the waste suction pipe 8 installed on the waste suction cup 5 is connected to an external dust suction device to suck in and discharge the grinding debris through the waste suction cup 5.

[0043] When the grinding is completed, the grinding disc 4 and the vacuum suction cup 13 are reset, and then the feeding hydraulic push rod 9 is started to push the ground electrode sheet out of the grinding receiving frame 3.

[0044] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
