Technical Field

[0002] During the battery manufacturing process, the cleaning effect of the electrode is a key factor in ensuring the quality of the tab welding. Due to the limited focal length of the laser, a negative pressure adsorption platform is required to ensure a stable cleaning distance. However, due to the limitations of the front-end process production, the ductility of the electrode after rolling is inconsistent, which will cause the electrode to arch on the platform. The negative pressure cannot adsorb the electrode flat, so the electrode needs to be assisted flattened. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Depend on Figures 1 to 3 A pole piece auxiliary flattening device for laser cleaning is provided, comprising:

[0024] Bottom plate 1, bottom plate 1 is fixedly installed on the main plate of the whole machine;

[0025] Connecting plate 2, connecting plate 2 is fixedly mounted on base plate 1;

[0026] The flattening mechanism 3 is installed at one end of the connecting plate 2 away from the bottom plate 1 and is used to flatten the pole piece.

[0027] The flattening mechanism 3 can be installed on the entire machine through the bottom plate 1 , so that the pole piece can be flattened by the flattening mechanism 3 .

[0028] The flattening mechanism 3 includes a cylinder 31 fixedly connected to the end of the connecting plate 2 away from the bottom plate 1 and a pressing plate 32 whose extension and contraction is controlled by the cylinder 31. The pressing plate 32 is made of non-metallic material. At the same time, the cylinder 31 is equipped with a hard limit, a pressure regulating valve and a speed regulating valve. The hard limit ensures that the pressing depth of the pressing plate 32 is constant and does not affect the adsorption effect of the negative pressure platform. The speed regulating valve is used to adjust the pressing speed of the cylinder 31 to ensure that the electrode is not affected by the impact force. The pressure regulating valve is used to adjust the pressure of the pressing plate 32 to ensure that the pressure of the pressing plate 32 is balanced and less than the adsorption force caused by the negative pressure platform.

[0029] The telescopic end of the cylinder 31 is controlled by a program to extend and retract, and the telescopic end of the cylinder 31 drives the pressing plate 32 to extend and retract, so that the pressing plate 32 flattens the pole piece.

[0030] A guide mechanism 4 is provided between the pressure plate 32 and the cylinder 31 to guide the movement of the pressure plate 32. The guide mechanism 4 includes a slide rail 41 fixedly connected to the side of the cylinder 31 away from the connecting plate 2, a sliding plate 42 slidably connected to the slide rail 41, and a mounting plate 43 fixedly connected to the bottom of the sliding plate 42. The bottom of the mounting plate 43 is fixedly connected to the top of the pressure plate 32. The telescopic end of the cylinder 31 is fixedly mounted on the top of the mounting plate 43, and a gap is left between the telescopic end of the cylinder 31 and the sliding plate 42.

[0031] The telescopic end of the cylinder 31 extends downward to drive the mounting plate 43 fixedly connected thereto to move downward. The mounting plate 43 can drive the pressing plate 32 fixedly connected thereto to move downward synchronously during the downward movement. The mounting plate 43 can also drive the sliding plate 42 fixedly connected thereto to move downward during the downward movement. The sliding plate 42 can slide on the slide rail 41 during the downward movement. The cooperation between the slide rail 41 and the sliding plate 42 can prevent the mounting plate 43 from deviating during the movement. Since the mounting plate 43 is fixedly connected to the pressing plate 32, the pressing plate 32 can also be prevented from deviating during the movement. Therefore, under the cooperation of the slide rail 41, the sliding plate 42 and the mounting plate 43, the movement of the pressing plate 32 can be guided.

[0032] Similarly, when the telescopic end of the cylinder 31 moves upward and contracts, the pressing plate 32 can be moved upward, so that the pressing plate 32 can be driven to contract under the action of the cylinder 31.

[0033] A protrusion 321 is fixedly connected to the bottom of the end of the pressure plate 32 away from the connecting plate 2, and the side of the protrusion 321 away from the pressure plate 32 is an arc surface. The arc surface of the protrusion 321 is used to contact the pole piece, and the arc surface of the protrusion 321 is smooth. The protrusion 321 is made of non-metallic material. The pressure plate 32 drives the protrusion 321 to move downward to press the pole piece, and the arc surface that contacts the pole piece is smooth and has no burrs or edges on the surface, which can ensure that the pole piece will not be damaged.

[0034] The width of the pressure plate 32 is less than half the width of the coating area because the arched area is in the middle of the electrode and the closer to the middle the more arched it is, the greater the arch is. Therefore, if the pressure plate 32 is too long, the flattening effect will decrease. Therefore, the width of the pressure plate 32 is set to be less than half the width of the coating area.

[0035] When the present application is in use, the arc surface of the protrusion 321 is the part that contacts the electrode. The cylinder 31 is extended and retracted by controlling the program, so that the protrusion 321 flattens the electrode. The electrode is flattened by the flattening mechanism 3, so that the negative pressure platform can adsorb and flatten the electrode, thereby ensuring the smoothness of the electrode during the laser cleaning process, reducing the arching phenomenon caused by inconsistent ductility of the electrode, and improving the laser cleaning effect.

[0036] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
