Description

Technical Field

[0001] The utility model belongs to the technical field of pole piece glue sticking, and in particular relates to a positive pole protective glue anti-bubble glue head mechanism and a glue sticking machine. Background Art

[0002] The winding process is an important production process in the production process of lithium-ion batteries. The pole pieces produced in the electrode process are cut by a winding needle and a cutting knife to form a battery cell. Hardware cutting is generally used for pole piece cutting. As the service life of the cutting knife is consumed, the pole piece cutting will form a burr cloak, affecting the safety of lithium-ion batteries. In order to solve this hidden danger, the insulating tape is usually applied after the pole piece is cut to ensure battery safety. The working actions are: glue suction block preparation → pole piece cutting → tape application. Because the glue suction block preparation is a vacuum adsorption tape, it is easy to generate bubbles when air is introduced in the subsequent ironing process, and wrinkles are formed after passing through the roller. In severe cases, it will cause diaphragm wrinkles and affect battery performance.

[0003] Therefore, a positive electrode protective glue anti-bubble glue head mechanism and a glue sticking machine are designed to solve the technical problem of bubbles between the electrode and the adhesive tape after the two are pasted together in the prior art. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The winding process is an important production process in the production process of lithium-ion batteries. The pole pieces produced in the electrode process are cut by a winding needle and a cutting knife to form a battery cell. Hardware cutting is generally used for pole piece cutting. As the service life of the cutting knife is consumed, the pole piece cutting will form a burr cloak, affecting the safety of lithium-ion batteries. In order to solve this hidden danger, the insulating tape is usually applied after the pole piece is cut to ensure battery safety. The working actions are: glue suction block preparation → pole piece cutting → tape application. Because the glue suction block preparation is a vacuum adsorption tape, it is easy to generate bubbles when air is introduced in the subsequent ironing process, and wrinkles are formed after passing through the roller. In severe cases, it will cause diaphragm wrinkles and affect battery performance.

[0031] In order to solve the above technical problems, a positive electrode protective glue anti-bubble glue head mechanism is provided, comprising: a glue suction block 2 and a glue roller 7; and the glue roller 7 is arranged above the glue suction block 2 to form a roller gap between the two; wherein the glue roller 7 contacts and rolls with the glue roller 7 when the adhesive tape and the electrode piece are bonded and pass through the roller gap to squeeze out the bubbles between the adhesive tape and the electrode piece; a glue roller is arranged on the glue suction block, so that when the electrode piece and the adhesive tape pass through the roller gap between the rubber roller and the glue suction block after being bonded, the bubbles between the electrode piece and the adhesive tape are squeezed out by the rotation of the rubber roller.

[0032] In some embodiments, Figure 3 As shown, the clamping block 4 is a concave block, and the center of its upper end surface is recessed to form a clamping groove 40 . The outer contour of the glue sucking block 2 matches the clamping groove 40 , so that the glue sucking block 2 can be embedded in the clamping groove 40 .

[0033] In some embodiments, a rotating shaft 6 passes through the rubber roller 7, and the two ends of the rotating shaft 6 are respectively connected to two vertical plates fixed on the upper end surface of the clamping block 4. Figure 2As shown, at this time, there is a certain gap between the rubber roller 7 and the upper end surface of the clamping block 4, that is, the upper end surface of the glue absorbing block 2, which is the pressure roller gap, for the electrode with the adhesive tape pasted to pass through. The adhesive tape is placed on the upper surface of the glue absorbing block 2, and negative pressure is generated in the holes opened on the upper surface of the glue absorbing block 2 to absorb the adhesive tape. When the electrode cut by the double cam cutting mechanism is transmitted to the upper part of the adhesive tape, it is continuously transmitted after being bonded with the adhesive tape. Due to the negative pressure in the holes on the upper surface of the glue absorbing block 2, there will be a certain gap between the adhesive tape and the electrode during the movement. At this time, the bonded electrode and the adhesive tape are transmitted to the bottom of the rubber roller 7. When passing through the pressure roller gap, they contact and rub with the rubber roller 7, so that the rubber roller 7 rotates, squeezes the connection between the electrode and the adhesive tape, and discharges the air between the two.

[0034] On the other hand, a glue laminating machine is also provided, which adopts the glue laminating mechanism as described above, wherein the glue laminating machine comprises a glue paper roller 1 on which glue paper is wound for bonding with the electrode.

[0035] In summary, by arranging a rubber roller on the glue absorbing block, after the electrode piece is attached to the adhesive paper, when the electrode piece passes through the roller gap between the rubber roller and the glue absorbing block, the bubbles between the electrode piece and the adhesive paper are squeezed out by the rotation of the rubber roller.
