Precise gluing device for corrosive aluminum foil

Abstract

The invention relates to a gluing device, in particular to a precise gluing device for corrosive aluminum foil. The precise gluing device for the corrosive aluminum foil comprises a base, guide railsand guide columns, a placing portion is slidably arranged among the guide rails, a positioning portion is slidably arranged among the guide columns, and the aluminum foil is evenly placed on the positioning portion at intervals. Second screw rods rotate, so that second nut blocks drive a pressing plate to move downwards slowly at a constant speed, a piston plate extrudes the glue in a glue containing box downwards slowly in the glue containing box, and the flowing speeds of the glue flowing out of nozzles are the same, so that the glue is uniformly and slowly extruded on the surface of the aluminum foil which moves downwards at a constant speed, and the glue on the surface of the aluminum foil is uniform in thickness and smooth; and when the glue flows out of the nozzles, the glue is extruded towards the middle of trapezoidal grooves due to the flow guide effect of inclined planes on the two sides of each trapezoidal groove, so that the phenomenon of non-uniform gluing on the surface of the aluminum foil due to bubbles generated when the glue flows out of the trapezoidal grooves can be prevented.

Description

technical field [0001] The invention relates to a gluing device, in particular to a precise gluing device for corroded aluminum foil. Background technique [0002] The patent with the application number CN201821861121.5 discloses a capacitor aluminum foil gluing mechanism, which includes a base, and two symmetrical support plates are fixedly installed on the top of the base. The connecting shaft, the side of the two connecting shafts close to each other is fixedly installed with the same roller, the outer side of the roller is wound with a roll, the side of the roll away from the roller is fixedly connected with a moving plate, and the base is provided with There is a moving chamber, and a connecting hole is opened on the inner wall of the top of the moving chamber. The bottom of the rolling cloth penetrates the connecting hole and extends into the moving chamber. By spraying glue evenly on the brush, and then turning the brush , you can use the brush to evenly apply the gl...

Problems solved by technology

[0003] Although the above-mentioned prior art realizes the function of applying glue on the surface of the aluminum foil body, turning the brush during the glue application process will cause the glue to splash, and too much glue remaining on the brush makes it difficult to clean the brush. This will cause a great waste of glue; on the other hand, when the moving plate pulls one end of the aluminum foil body to move, it will stretch the aluminum foil and break the structure of the aluminum foil itself, thus causing product quality problems in the aluminum foil; On the one hand, the rough structure of the brush itself and the bumps in the moving process of the aluminum foil will cause streaks of glue on the surface of the aluminum foil and the thickness of the glue surface is different, and the dimensional accuracy of the glue is low; finally, the existing technology only It can apply glue to a piece of aluminum foil, and each time before applying glue to the aluminum foil, roll the roll cloth on the outside of the drum, then fix one end of the roll cloth on the moving plate, and then fix the aluminum foil body on the outside of the roll cloth, Such operation is very inconvenient and the production efficiency is low
