Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and specifically relates to a device for cleaning residual paste on the surface of a plate electrode. Background Art

[0002] In the plate electrode manufacturing process of the battery industry, the cleaning of residual paste during the coating process has always been a very crucial step. The residual paste remaining on the plate receiving belt will adhere to the surface of the plate electrode during plate receiving. If it cannot be cleaned off, after the plate electrode is cured and dried, the hardened residual paste protruding from the surface of the plate may pierce the separator paper after battery assembly, causing battery short circuit.

[0003] Currently, when cleaning the lead paste on the plate electrode, usually a lead paste brush is used to brush off the excess lead paste. However, after the existing lead paste brush is cleaned, there will still be a small amount of residual material scattered on the surface of the plate electrode, and it is not convenient to adjust the working range of the lead paste brush, and the adaptability to products of different specifications needs to be improved. Although some patent documents also disclose technical means of combining a nozzle to perform secondary cleaning on the residual paste, the installation structure of the nozzle cannot flexibly adjust the blowing height and position, and the cleaning effect on the residual paste on the surface of the plate electrode still needs to be further improved.

[0004] Therefore, those skilled in the art urgently need to develop a new device for cleaning residual paste on the surface of a plate electrode. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above technical problems, and the following technical solutions are proposed:

[0006] A device for cleaning residual paste on the surface of a plate electrode includes a paste coater, a lead paste brush, and a blowing pipe. Both ends of the lead paste brush are adjustably connected to the two side brackets at the discharging end of the paste coater through two connecting rod brackets. And a vertical adjusting rod is fixedly connected to one side bracket at the discharging end of the paste coater. The adjusting rod is connected with the blowing pipe in a liftable manner through a connecting component. The blowing pipe can be adjusted to rotate along the axial direction of the adjusting rod while being adjusted to lift along the adjusting rod.

[0007] Preferably, each connecting rod bracket includes a base, a first connecting plate, and a second connecting plate. The two bases are relatively fixed on the two side brackets at the discharging end of the paste coater. Both ends of the first connecting plate are respectively hinged to the base and one end of the second connecting plate through a pin shaft. One end of the pin shaft is provided with a pin head, and the other end is threadedly connected with a clamping nut. The other end of the second connecting plate is fixedly connected with the lead paste brush through an installation rod. With this setting, by loosening or tightening the clamping nut, the inclination angle of the first connecting plate and the second connecting plate can be adjusted, which is convenient for flexibly adjusting the spatial position of the lead paste brush and improves the application range of the device.

[0008] Preferably, the first connecting plate and the second connecting plate are respectively provided with a plurality of through holes matching the pin shafts along their respective length directions. This setting can adjust the connection position between the first connecting plate and the second connecting plate, and adjust the length of the entire connecting rod bracket, thereby facilitating the further expansion of the working range of the paste brush.

[0009] Preferably, the adjusting rod is a cylindrical rod. The connecting component includes a sliding sleeve and a fixed sleeve. The sliding sleeve and the fixed sleeve are connected by a horizontal rod. The inner hole of the sliding sleeve is matched with the outer diameter of the adjusting rod, and a set screw is penetrated through the side wall of the sliding sleeve. When the set screw is loosened, the sliding sleeve can rotate and slide up and down on the adjusting rod. When the set screw is tightened, the sliding sleeve is fixedly connected to the adjusting rod; the fixed sleeve is horizontally arranged, and a fixed rod is horizontally penetrated through the fixed sleeve. A plurality of pipe clamps matching the purging pipe are arranged below the fixed rod. The purging pipe is detachably connected below the fixed rod through the pipe clamps, and a plurality of purging holes facing the upper surface of the plate on the incoming material side of the paste applicator are evenly distributed on the lower side of the purging pipe. One end of the purging pipe is a blind end, and the other end is connected with a compressed air hose through a quick connector. This setting can conveniently adjust the height and angle of the purging pipe, improve the effect of residual paste cleaning, and at the same time, it is convenient to adjust the purging pipe to form a certain angle with the two side brackets at the discharging end of the paste applicator, so as to blow the residual paste cleaned from the plate to one side of the paste applicator for collection.
