Double-side adhesive tape adhering apparatus and double-side adhesive tape adhering method

Abstract

A double-side adhesive tape adhering apparatus comprises a supporting plate, an adhesive tape feeding mechanism set, an adhesive tape adhering mechanism set and a shearing mechanism set. The adhesive tape feeding mechanism set comprises a first adhesive tape feeding mechanism and a second adhesive tape feeding mechanism; the first adhesive tape feeding mechanism comprises a first adhesive tape feeding driving part and a first adhesive tape feeding part; the first adhesive tape feeding part is provided with a first adhesive tape feeding block and a first adhesive tape pressing spring plate; the second adhesive tape feeding mechanism comprises a second adhesive tape feeding driving part and a second adhesive tape feeding part; the second adhesive tape feeding part is provided with a second adhesive tape feeding block and a second adhesive tape pressing spring plate; the adhesive tape adhering mechanism set comprises a first adhesive tape adhering mechanism and a second adhesive tape adhering mechanism; the first adhesive tape adhering mechanism comprises a first adhesive tape adhering driver and a first adhesive tape adhering block; the second adhesive tape adhering mechanism comprises a second adhesive tape adhering driver and a second adhesive tape adhering block; and the adhesive tape feeding mechanism set drives the first adhesive tape feeding part and the second adhesive tape feeding part to enable an adhesive tape to be positioned at both sides of a pole piece, the adhesive tape adhering mechanism set drives the first adhesive tape adhering block and the second adhesive tape adhering block to enable the adhesive tape to press the pole piece and the shearing mechanism set shears the adhesive tape. By the double-side adhesive tape adhering apparatus, accuracy of the adhesive tape adhering position can be improved; and the double-side adhesive tape adhering apparatus can be suitable for the pole piece with a small width. The present invention relates to a double-side adhesive tape adhering method.

Description

technical field [0001] The invention relates to a production device of electric cores, in particular to a double-sided gluing device and a double-sided gluing method. Background technique [0002] As a kind of clean energy, lithium battery has been widely used in various electronic products, such as smart phones, Notebook computers, digital cameras and portable small appliances, etc. The main structure of a lithium battery includes a casing and a lithium-ion cell set in the casing. Usually, the cell is composed of a positive electrode, an upper diaphragm, a negative electrode and a lower diaphragm. The positive and negative electrodes are important components of the lithium-ion cell. part. The positive and negative tabs of the lithium battery cell are welded with positive and negative tabs that export energy. In order to ensure the safety of the battery, it is generally necessary to paste glue on the upper and lower sides of the weld between the positive and negative tabs ...

AI Technical Summary

Problems solved by technology

However, since this kind of glue-applying mechanism first cuts the tape and then absorbs it, for a pole piece with a narrow width, the position of the cut-off tape on the glue-absorbing block will change greatly, so that the tape sticks The position on the pole piece is inaccurate, and the error range of the sticking position of the tape is relatively large, so it cannot meet the production process requirements

Moreover, since it is impossible to mechanically apply glue to the narrow pole piece, the existing glue is manually pasted. Not only the efficiency of glue application is low, but also the error of glue application is large, and the quality of the pole piece cannot be guaranteed.
