DETAILED DESCRIPTION

[0016] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a tab cutting device for lithium battery production and processing, including a support frame 1 and a material cutting mechanism 7. The top of the support frame 1 is fixedly installed with an mounting plate 2, and the top of the mounting plate 2 is fixedly installed with two sets of side plates 3. A lower positioning frame 5 is fixedly installed on one side of the side plate 3. A material drop groove 6 is opened on the lower positioning frame 5. A driving mechanism 4 for driving the cutting mechanism 7 to move up and down for cutting is provided on the side plate 3. A pressing mechanism 8 for preventing the material to be cut from moving is provided on the lower positioning frame 5.

[0018] The support frame 1, mounting plate 2, and side plate 3 can support the drive mechanism 4. The tab material to be cut is then placed on the lower positioning frame 5. The drive mechanism 4 then drives the cutting mechanism 7 to move down, so that it can cooperate with the lower positioning frame 5 to complete the cutting step. Before the drive mechanism 4 drives the cutting mechanism 7 to descend, the clamping mechanism 8 can first contact the tab material to clamp the tab material and ensure the cutting accuracy.

[0019] Please see Figure 1 , Figure 2 and Figure 3 The driving mechanism 4 includes a vertical plate 9, a driving cylinder 10, a slide rail 11, and a slider 12. An "L"-shaped vertical plate 9 is fixedly installed on the top of the cutting mechanism 7. Two sets of slide rails 11 are fixedly installed on one side of the vertical plate 9. A slider 12 is slidably connected on the slide rail 11. One side of the slider 12 is fixedly connected to the cutting mechanism 7. A driving cylinder 10 is fixedly installed on the top of the vertical plate 9. The output end of the driving cylinder 10 is fixedly connected to the moving frame 13.

[0020] When the cutting mechanism 7 needs to be moved down for cutting, the drive cylinder 10 operates and pushes the cutting mechanism 7 down. In this way, the cutting mechanism 7 and the lower positioning frame 5 can work together to complete the cutting of the tab. When the cutting mechanism 7 descends, the slide rail 11 and the slider 12 can be used for limiting to ensure the descent accuracy of the cutting mechanism 7.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The cutting mechanism 7 includes a movable frame 13, connecting columns 14 and a cutting blade 15. One side of the movable frame 13 is fixedly connected to the slider 12. Two sets of connecting columns 14 are fixedly installed at the bottom of the movable frame 13, and the cutting blade 15 is fixedly connected to the bottom of the connecting columns 14.

[0022] The operation of the drive cylinder 10 pushes the moving frame 13, the connecting column 14 and the cutting blade 15 to move downward, so that the cutting of the tab can be completed by the descending cutting blade 15.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The pressing mechanism 8 includes a limiting rod 16, a pressure seat 17, and a spring 18. Two sets of limiting rods 16 are slidably connected on the movable frame 13. The pressure seat 17 is fixedly connected to the bottom of the limiting rod 16 and outside the cutting blade 15. The spring 18 is fixedly connected to the top of the pressure seat 17 and outside the limiting rod 16. The top of the spring 18 is fixedly connected to the movable frame 13.

[0024] When the drive mechanism 4 operates and drives the cutting mechanism 7 to descend, the pressure seat 17 will first come into contact with the electrode material on the lower positioning frame 5. Then, the continuous descent of the drive mechanism 4 can squeeze the pressure seat 17 and use the spring 18 to press and position the electrode on the lower positioning frame 5 to prevent the electrode from being misaligned during the cutting process.

[0025] Please see Figure 1 , Figure 2 and Figure 3 The support frame 1 is provided with a walking groove 19. A receiving cart 20 is provided on the walking groove 19 and below the lower positioning frame 5. The bottom of the receiving cart 20 is inclined. A handle 21 is fixedly connected to one side of the receiving cart 20. A hollow receiving frame 22 is fixedly connected to the bottom of the lower positioning frame 5 and at the position corresponding to the dropping groove 6.

[0026] The cut material falls through the chute 6 and is discharged into the receiving cart 20 through the hollow receiving frame 22, thus completing the centralized collection of materials. The bottom of the receiving cart 20 is inclined to prevent excessive accumulation of materials.

[0027] In use, firstly, the support frame 1, mounting plate 2, and side plate 3 support the drive mechanism 4. Then, the tab material to be cut is placed on the lower positioning frame 5. Next, the drive mechanism 4 moves the cutting mechanism 7 downwards, thus cooperating with the lower positioning frame 5 to complete the cutting step. Before the drive mechanism 4 moves the cutting mechanism 7 downwards, the clamping mechanism 8 can first contact the tab material to clamp it, ensuring cutting accuracy. When the cutting mechanism 7 needs to be moved downwards for cutting, the drive cylinder 10 operates, pushing the cutting mechanism 7 downwards. This allows the cutting mechanism 7 and the lower positioning frame 5 to cooperate in cutting the tab. During the descent of the cutting mechanism 7, the slide rail 11 and slider 12 can be used for limiting the movement, ensuring the cutting accuracy. The descent accuracy of the cutting mechanism 7 is achieved by the operation of the drive cylinder 10, which pushes the moving frame 13, connecting column 14, and cutting blade 15 downwards. This allows the cutting blade 15 to cut the electrode tabs. When the drive mechanism 4 operates and drives the cutting mechanism 7 downwards, the pressure seat 17 first contacts the electrode tab material on the lower positioning frame 5. Subsequently, the continuous descent of the drive mechanism 4 can compress the pressure seat 17 and use the spring 18 to press and position the electrode tabs on the lower positioning frame 5, preventing the electrode tabs from misaligning during the cutting process. The cut material falls through the dropping chute 6 and is discharged into the inside of the receiving cart 20 through the hollow receiving frame 22, thus completing the centralized collection of materials. Moreover, the bottom of the receiving cart 20 is inclined to prevent excessive accumulation of materials.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
