Description

Technical Field

[0001] The utility model relates to the technical field of battery production, and particularly relates to a reinforcing rib self-cleaning mechanism. Background Art

[0002] After the ear of the battery pole piece is die-cut and formed, the ear needs to be flattened by passing through a roller and then directly used for winding. Since the width of the ear becomes narrower and the thickness of the ear is thin after film cutting, when the winding machine runs at a high speed (speed > 20 m / min), the ear passing through the roller is prone to folding, wrinkling and breaking, which affects the product quality. Therefore, in the prior art, a reinforcing rib mechanism is usually used to stamp or roll a reinforcing rib on the ear to increase the strength and rigidity of the ear, so as to reduce the folding, wrinkling and breaking of the ear, improve the strength and rigidity of the ear, reduce the defects of the ear, and thus improve the product yield. However, after the reinforcing rib mechanism embosses the pole piece, metal powder will remain on the rubber-covered wheel, which will cause secondary pollution to the subsequent pole piece and shorten the service life of the rubber-covered wheel. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a reinforcing rib self-cleaning mechanism, which can clean the metal powder remaining on the rubber-covered wheel after embossing the pole piece, reduce the secondary pollution caused by the rubber-covered roller to the pole piece, and increase the service life of the rubber-covered wheel at the same time.

[0024] Specifically, the rubber-coated wheel assembly 1 includes a rubber-coated wheel fixing seat 11 and a rubber-coated wheel 12, and the rubber-coated wheel 12 is pivotally arranged on the rubber-coated wheel fixing seat 11.

[0025] Specifically, the embossing wheel assembly 2 includes a knob adjustment module 21, a first embossing wheel lifting cylinder 22, a second embossing wheel lifting cylinder 23, a first embossing wheel 24, and a second embossing wheel 25. The first embossing wheel lifting cylinder 22 and the second embossing wheel lifting cylinder 23 are relatively movably arranged on the rotation adjustment module 21 and can be driven to move left and right by the rotation adjustment module 21; the cylinder shaft of the first embossing wheel lifting cylinder 22 faces the rubber-coated wheel 12 and is connected to the first embossing wheel 24, and can drive the first embossing wheel 24 to expand and contract towards the rubber-coated wheel 12; the cylinder shaft of the second embossing wheel lifting cylinder 23 faces the rubber-coated wheel 12 and is connected to the second embossing wheel 25, and can drive the second embossing wheel 25 to expand and contract towards the rubber-coated wheel 12.

[0026] Specifically, as shown in conjunction with Figure 2 , Figure 3 , the rubber-coated wheel self-cleaning assembly 3 includes a sticky dust paper winding and unwinding assembly 31 and a rubber-coated pressing wheel assembly 32.

[0027] The adhesive dust paper unwinding and rewinding assembly 31 includes a main unwinding motor 311, a magnetic powder clutch 312, an adhesive dust paper unwinding roller 313 and an adhesive dust paper rewinding roller 314. The adhesive dust paper unwinding roller 313 and the adhesive dust paper rewinding roller 314 are pivotally arranged front and back below the rubber-coated wheel 12. The main unwinding motor 311 is connected to the adhesive dust paper rewinding roller 314 through the magnetic powder clutch 312. The adhesive dust paper is actively unwound through the adhesive dust paper unwinding roller 313 and automatically recycled through the adhesive dust paper rewinding roller 314 after cleaning.

[0028] The rubber-coated pressure wheel assembly 32 is located between the adhesive dust paper unwinding roller 313 and the adhesive dust paper rewinding roller 314, and it includes an adjustment slide rail 321, a first rubber-coated pressure wheel telescopic cylinder 322, a second rubber-coated pressure wheel telescopic cylinder 323, a first rubber-coated pressure wheel 324 and a second rubber-coated pressure wheel 325.

Combining the first rubber-coated pressure wheel telescopic cylinder 322 and the second rubber-coated pressure wheel telescopic cylinder 323 to control the first rubber-coated pressure wheel 324 and the second rubber-coated pressure wheel 325, the adhesive dust paper intermittently removes the residual metal powder on the surface of the rubber-coated wheel to keep the roller surface clean, and the dusted paper tape is collected on the adhesive dust paper rewinding roller 314; for pole pieces with different process widths, the rotation adjustment module 21 and the adjustment slide rail 321 are respectively used to perform retooling adjustments on the embossing wheel and the rubber-coated pressure wheel.
