Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of laser cleaning equipment, and particularly to a negative pressure adsorption plate, an adsorption device and a laser cleaning equipment. Background Art
[0002] The pole piece includes a metal foil layer and a coating layer, and the coating layer is coated on the surface of the metal foil layer. In order to weld the pole piece to the outside, welding windows need to be provided on both sides of the pole piece so that the metal foil layer is exposed through the welding windows, and then the metal foil layer can be welded to the outside, that is, an empty foil area is provided on the pole piece, and the empty foil area of the pole piece is welded to the outside, wherein the welding windows on both sides of the pole piece are symmetrically arranged on the pole piece. In the existing manufacturing process, the pole piece is fully coated, that is, the metal foil layer is completely covered by the coating layer. Therefore, some materials on both sides of the pole piece are required to form welding windows on both sides of the pole piece respectively.
[0003] Generally, a laser cleaning equipment is used to clean the pole piece to form welding windows on both sides of the pole piece. In the related art, during laser cleaning, the pole piece is adsorbed on a negative pressure adsorption plate, for example, the pole piece is adsorbed on the adsorption plate disclosed in CN111871963A, with the A side of the pole piece facing up, and then the coating material in the cleaning area of the A side is cleaned by laser to form a welding window on the A side of the pole piece, that is, an avoidance groove is formed on the pole piece, and then the pole piece is flipped, adsorbed on the negative pressure adsorption plate with the B side of the pole piece facing up, and then the coating material in the cleaning area of the B side is cleaned by laser, wherein the cleaning area of the A side and the cleaning area of the B side are symmetrically arranged on the pole piece.
[0004] However, for materials that are difficult to clean, such as the cathode ternary material, the change in the laser cleaning focal length has a great influence on the cleaning effect. Since the cleaning of the A side has been completed, grooves will be formed in the cleaning area of the A side; when cleaning the B side, since the A side is in contact with the adsorption plate and grooves are formed in the cleaning area of the A side, voids will be formed between the pole piece and the adsorption plate at the grooves; and since the adsorption surface of the adsorption plate is covered with adsorption holes, adsorption holes will correspond to the voids, resulting in obvious depressions in the cleaning area of the pole piece during the adsorption process. The above depressions will cause a large difference in the focal lengths between the edge cleaning area and the central cleaning area of the B side, making the cleaning effects of the edge cleaning area and the central cleaning area of the B side inconsistent, which will lead to problems of over-cleaning and incomplete cleaning. Specifically, when the edge cleaning area of the B side is cleaned, the central cleaning area of the B side is not cleaned; when the central cleaning area of the B side is cleaned, the edge cleaning area of the B side is over-cleaned, resulting in the pole piece being easily punctured, thus posing risks of incomplete cleaning and pole piece puncture in laser cleaning.
[0005] Therefore, for materials that are difficult to clean, it is currently urgent to solve the problem of inconsistent cleaning effects between the edge cleaning area and the central cleaning area, and further avoid the problems of incomplete cleaning and pole piece puncture. Summary of the Invention
[0006] The purpose of the present disclosure is to overcome the deficiencies in the prior art, and to provide a negative pressure adsorption plate, an adsorption device and a laser cleaning device, which can solve the problem of inconsistent cleaning effects in the edge cleaning area and the central cleaning area, and further avoid the problems of incomplete cleaning and piercing of the electrode sheet.
[0007] The purpose of the present disclosure is achieved through the following technical solutions:
[0008] A negative pressure adsorption plate is provided with a negative pressure adsorption surface, on which a plurality of negatively pressured adsorption holes arranged in an array are opened. Each negatively pressured adsorption hole is used for adsorbing the electrode sheet. The negative pressure adsorption surface includes an adsorption area and a blank area. A plurality of negatively pressured adsorption holes are arranged in an array in the adsorption area, and each negatively pressured adsorption hole is arranged in a dislocation manner with the blank area. The blank area is used for corresponding to the cleaning area of the electrode sheet.
[0009] In some embodiments, the extending direction of the adsorption area is parallel to the extending direction of the negative pressure adsorption plate.
[0010] In some embodiments, the extending direction of the blank area is parallel to the extending direction of the negative pressure adsorption plate.
[0011] In some embodiments, the width of the blank area is 18 mm to 20 mm.
[0012] In some embodiments, the number of the adsorption areas is two, and the blank area is located between the two adsorption areas.
[0013] In some embodiments, the two adsorption areas are symmetrically arranged with respect to the blank area.
[0014] In some embodiments, the distance between adjacent two negatively pressured adsorption holes is 7 mm to 9 mm.
[0015] In some embodiments, the diameter of each negatively pressured adsorption hole is 0.5 mm to 1.5 mm.
[0016] An adsorption device includes a plurality of negative pressure adsorption plates according to any one of the above embodiments. The adsorption device further includes a fixing plate, on which a plurality of installation grooves arranged at intervals in sequence are opened. A plurality of negative pressure adsorption plates are respectively fixedly embedded in the plurality of installation grooves.
[0017] A laser cleaning device includes the negative pressure adsorption plate according to any one of the above embodiments.
[0018] Compared with the prior art, the present disclosure has at least the following advantages:
[0019] Due to the misalignment of the vacuum adsorption holes and the blank area, and the blank area is correspondingly arranged with the cleaning area of the pole piece. When laser cleaning the B side of the pole piece, the blank area is correspondingly arranged with the welding window of the A side of the pole piece. Also, due to the misalignment of each negative pressure adsorption hole and the blank area, that is, the negative pressure adsorption plate does not adsorb the cleaning area of the pole piece, which means the negative pressure adsorption plate will not adsorb the groove on the A side, avoiding obvious depressions in the cleaning area of the pole piece, avoiding the problem of a large difference in the focal lengths between the edge cleaning area and the center cleaning area on the B side, avoiding the problem of inconsistent cleaning effects between the edge cleaning area and the center cleaning area on the B side, avoiding the problem that the cleaning area on the B side is not cleaned thoroughly, and at the same time avoiding the problem of over-cleaning on the B side, thereby avoiding the problem of the pole piece being penetrated by the laser.
