Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and more specifically, it relates to a dust removal device for electrode sheets used in the production and processing of lithium battery binders. Background Technology

[0002] In the lithium battery production process, active materials, conductive agents, and solvents need to be bonded together with binders, and then bonded to metal foil sheets to form lithium battery electrodes. During this process, dust removal is required for the battery electrodes.

[0003] A search revealed that Chinese utility model patent application number CN202221340673.8 discloses a dust removal device for electrode sheets used in the production and processing of lithium battery binders. The device includes a dust removal box, a conveyor fixedly installed inside the dust removal box, an inlet end and an outlet end respectively opened on both sides of the dust removal box, a hydraulic telescopic rod fixedly installed on the top of the dust removal box, a guide plate fixedly installed at the bottom end of the hydraulic telescopic rod, and a rotating shaft uniformly rotatably connected to the bottom surface of the guide plate.

[0004] In use, the electrode sheet is conveyed to the bottom of the brush plate by a conveyor. Depending on the intensity of cleaning the electrode sheet surface, the hydraulic telescopic rod is driven to adjust the position of the guide plate, moving the brush plate at the bottom of the guide plate to the surface of the electrode sheet and making contact with it. Then, the first motor drives the rotating shaft to rotate, which in turn drives the brush plate to rotate, thereby removing dust from the surface of the electrode sheet.

[0005] It can remove dust from one side of the electrode, but it is not convenient to remove dust from the other side of the electrode, and it is not convenient to remove dust from both sides of the electrode at the same time, which reduces the efficiency of electrode dust removal. In addition, during the rotation of the brush, the electrode on the conveyor will move, and the electrode is not stable during dust removal. The electrode will fall off the conveyor, affecting the effect of electrode dust removal. At the same time, the electrode is easily damaged by falling. Utility Model Content

[0023] Please see Figures 1-5 A dust removal device for electrode sheets used in the production and processing of lithium battery adhesives includes a fixed platform 1. A rotating shaft 2 is rotatably connected to the top of the fixed platform 1. A fixed seat 3 is fixedly connected to the top of the rotating shaft 2. Two electrode sheet clamping mechanisms are symmetrically arranged on the fixed seat 3. A first motor 4 that drives the rotating shaft 2 to rotate is fixedly installed on the fixed platform 1. A fixed frame 5 is slidably arranged on the fixed platform 1 through an adjustment mechanism. A sliding plate 6 is slidably arranged on the fixed frame 5. A first electric cylinder 7 is fixedly connected to the sliding plate 6. A vertical seat 8 is fixedly connected to the telescopic end of the first electric cylinder 7. Two sliding rods 32 are fixedly connected to the top of the vertical seat 8. Both sliding rods 32 slide in cooperation with the sliding plate 6 to ensure stable sliding of the vertical seat 8. Two dust collection boxes 9 are slidably arranged on the side end of the vertical seat 8. Multiple brushes 10 are fixedly installed on one side of each of the two dust collection boxes 9. Multiple dust collection ports 11 are provided on one side of each of the two dust collection boxes 9. Dust collection pipes 12 that communicate with a dust collection device are connected to the two dust collection boxes 9.

[0024] Specifically, the electrode plate fixed on the mounting base 3 is rotated to the middle of the two dust collection boxes 9. The two dust collection boxes 9 and multiple brushes 10 are moved on both sides of the electrode plate by sliding the slide plate 6. The brushes 10 clean both sides of the electrode plate, and the two dust collection boxes 9 suck up the cleaned dust, which makes it easy to remove dust from both sides of the electrode plate at the same time and improves the efficiency of removing dust from the electrode plate.

[0025] Please see Figure 2 A mounting plate 13 is fixedly connected to the mounting frame 5. A second motor 14 is fixedly connected to the mounting plate 13. A turntable 15 is fixedly connected to the output end of the second motor 14. A locating post 16 is fixedly connected to the bottom of the turntable 15 off-center. A strip groove 17 is provided on the slide plate 6. The locating post 16 is inserted into the inside of the strip groove 17 to facilitate driving the slide plate 6 to slide back and forth.

[0026] Specifically, the second motor 14 drives the turntable 15 and the shifter 16 to rotate. As the shifter 16 rotates with the turntable 15, it drives the slide plate 6 to slide back and forth.

[0027] Please see Figure 1 and Figure 2 The adjustment mechanism includes a second electric cylinder 18. Two slide grooves 19 are symmetrically arranged on the fixed platform 1. Slide seats 20 are slidably arranged inside the two slide grooves 19. The two slide seats 20 are fixedly connected to the fixed frame 5. The second electric cylinder 18 is fixedly installed on the fixed platform 1. The telescopic end of the second electric cylinder 18 is fixedly connected to the corresponding slide seat 20, which facilitates the adjustment of the position of the two dust collection boxes 9.

[0028] Specifically, when the fixed base 3 needs to be rotated, the second electric cylinder 18 pulls the slide 20 and the fixed frame 5 to move, so that the two dust collection boxes 9 move away from the fixed base 3. During the rotation of the fixed base 3, the fixed base 3 is prevented from colliding with the two dust collection boxes 9.

[0029] Please see Figure 3 The vertical base 8 has an adjustment groove 21 on its side. A bidirectional screw 22 is rotatably connected inside the adjustment groove 21. Two adjustment seats 23 are symmetrically threaded on the outside of the bidirectional screw 22. Both adjustment seats 23 are slidably engaged with the adjustment groove 21. The two adjustment seats 23 are fixedly connected to the two dust collection boxes 9 respectively. A third motor 24 that drives the bidirectional screw 22 to rotate is fixedly installed at the bottom of the vertical base 8, which facilitates the adjustment of the distance between the two dust collection boxes 9.

[0030] Specifically, the third motor 24 drives the bidirectional screw 22 to rotate. The rotation of the bidirectional screw 22 causes the two adjusting seats 23 to move in opposite directions inside the adjusting groove 21. The two adjusting seats 23 respectively drive the two dust collection boxes 9 to move, which facilitates the adjustment of the distance between the two dust collection boxes 9 and the adjustment of the distance between the multiple brushes 10 on the two dust collection boxes 9 according to the thickness of the electrode.

[0031] Please see Figure 1 and Figure 5 The electrode clamping mechanism includes a clamping plate 25 and a third electric cylinder 26. The fixed base 3 is provided with two clamping grooves 27. The clamping plate 25 slides in the clamping grooves 27. The third electric cylinder 26 is fixedly installed on the top of the fixed base 3. The telescopic end of the third electric cylinder 26 is fixedly connected to the top of the clamping plate 25 to facilitate clamping and fixing the electrode. A rubber pad 28 is fixedly connected to the bottom end of the clamping plate 25 to increase the flexibility of the bottom end of the clamping plate 25 and protect the electrode. Slots 29 are provided on both sides of the bottom end of the clamping groove 27. A limit pad 30 is inserted into the slot 29. A fixing screw 31 that mates with the limit pad 30 is threaded on the fixed base 3 to limit the clamping plate 25 and prevent the clamping plate 25 from clamping the electrode with too much force, which could damage the electrode.

[0032] Specifically, by inserting one end of the electrode into the clamping groove 27, the third electric cylinder 26 pushes the clamping plate 25 downward to clamp and fix the electrode. This prevents the electrode from moving during dust removal, improves the stability of the electrode, and enhances the dust removal effect. According to the thickness of the electrode, the corresponding height limit pad 30 is inserted into the slot 29, and the fixing screw 31 is tightened to fix the limit pad 30. The limit pad 30 limits the clamping plate 25, preventing the clamping plate 25 from moving downward while it can stably clamp the electrode, thus preventing the clamping plate 25 from clamping the electrode with excessive force and damaging the electrode.

[0033] In summary, when using the overall equipment: First, adjust the distance between the two dust collection boxes 9 according to the rear end of the electrode, and adjust the height of the two dust collection boxes 9 using the first electric cylinder 7. Then, wipe the edge of the electrode where it needs to be clamped with a cloth, and insert the wiped edge of the electrode into the clamping groove 27. Then, push the clamping plate 25 downward using the third electric cylinder 26 to clamp and fix the electrode. Then, pull the fixing frame 5 and the two dust collection boxes 9 to the rearmost side using the second electric cylinder 18. Then, drive the rotating shaft 2 and the fixing seat 3 to rotate 180° using the first motor 4, and then push the second electric cylinder 18 to the rearmost side. The mounting bracket 5 and the two dust collection boxes 9 are moved so that the two dust collection boxes 9 are moved to both sides of the electrode sheet. At this time, multiple brushes 10 contact the two ends of the electrode sheet. Then, the second motor 14 drives the turntable 15 and the deflector 16 to rotate. As the deflector 16 rotates with the turntable 15, it drives the slide plate 6 to slide back and forth, so that the brushes 10 move on the surface of the electrode sheet and clean the surface of the electrode sheet. At the same time, the dust collection equipment connected to the outside of the dust collection pipe 12 works to suck away the generated dust. During the dust removal process of the electrode sheet, people can replace the electrode sheet on the other side of the mounting bracket 3.

[0034] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
