Description

Technical Field

[0001] This utility model relates to the field of electrode tab adhesive technology, specifically a battery electrode tab adhesive device. Background Technology

[0002] In the actual production process of lithium-ion batteries, there are strict requirements for dust, and there must be absolute insulation between the tab and the metal shell. If dust enters the tab or comes into contact with the metal shell, it may cause a short circuit in the battery. At the same time, in order to fix the tab and prevent it from bending and inserting into the core, causing a short circuit, it is necessary to apply adhesive to the tab that is welded to the connecting piece.

[0003] During the process of applying tape to the tabs, the tape needs to be applied smoothly and adhered to the tabs. The surface of the tape should not have obvious wrinkles. If the tape applied to the tabs is not adhered well or is wrinkled, dust can easily enter the core. In addition, existing tape application devices are prone to crushing or breaking the tabs to some extent, which can lead to tab damage. A broken tab can affect the quality of the battery and may even pose a significant safety hazard.

[0004] Therefore, there is a need for a battery tab adhesive application device that can smoothly apply the tape to the tab without damaging it. To this end, we propose a battery tab adhesive application device to solve the above problems. Utility Model Content

Telescopic cylinder 201 is installed in the fixed frame 104 top, when the device starts, telescopic cylinder 201 output starts work, and the connecting barrel 202 fixedly connected with it is driven to move downwards. Connecting barrel 202 is built -in movement roller 204, telescopic spring 205 and other components, and movement roller 204 and connecting barrel 202 inner wall slidingly connected, and multiple guide seat 206 fixedly connected with its one end around are placed in the guide window 203 around set up in connecting barrel 202 and can relatively slide, which makes movement roller 204 can relatively stably move in the connecting barrel 202 in the up and down direction. Movement roller 204 bottom fixedly connected with fixed station 207 is installed with multiple evenly distributed electric sucking disc 208, and electric sucking disc 208 can adsorb the adhesive tape, and prepare for the subsequent pasting operation

[0025] Further, installation grooves 209 are formed on both sides of the inner wall of the fixing frame 104, and rotating rollers 210 are arranged in the installation grooves 209. Fixed cylinders 211 are sleeved on both ends of the rotating rollers 210. One end of the fixed cylinders 211 away from the rotating rollers 210 is fixedly connected with the inner wall of the installation grooves 209. Elastic members 212 are sleeved on both ends of the rotating rollers 210. The rotating rollers 210 are connected with the fixed cylinders 211 through the elastic members 212. Top seats 213 are sleeved on the surfaces of the rotating rollers 210. One end of the top seats 213 is fixedly connected with the rotating rollers 210. Trigger seats 214 are fixedly connected on both sides of the fixed table 207. The trigger seats 214 are slidingly connected with the top seats 213. In the initial stage, due to the supporting action of the elastic members 212, the top seats 213 generate an upward supporting force on the fixed table 207, so that the fixed table 207 cannot easily move downward. With the continuous downward movement of the connecting cylinder 202 and the fixed table 207 and other components driven by the telescopic cylinder 201, the downward force on the fixed table 207 increases. Under the action of the trigger seats 214, the top seats 213 make the rotating rollers 210 rotate against the elastic force of the elastic members 212. When a certain limit force is reached, the elastic members 212 are compressed to a certain degree. The rotation of the top seats 213 changes the supporting action on the fixed table 207. The fixed table 207 can suddenly move downward to approach the battery tab 103, driving the adhesive tape attached thereto. After the adhesive tape is moved to the appropriate position under the driving of the fixed table 207, the adhesive tape contacts the surface of the battery tab 103, completing the pasting action. At the same time, the electric suction cup 208 stops the adsorption action and releases the adhesive tape. Thus, one complete battery tab 103 adhesive pasting operation is completed.

[0026] The upward and downward movement of the connecting cylinder 202 and the fixed table 207 and other components is controlled by the telescopic cylinder 201. The stability of the movement of the movement roller 204 and the fixed table 207 is ensured by the cooperation of the guide window 203 and the guide seat 206. The adhesive tape can be accurately sent to the position of the tab 103 where the adhesive tape is needed, which is beneficial to improve the accuracy of the adhesive pasting and ensure the adhesive pasting quality.

[0027] The arrangement of the movement roller 204, the telescopic spring 205 and other components enables the adhesive tape to maintain a relatively stable state during the adsorption and movement, reduces the occurrence of shaking, deviation and other situations, enables the adhesive tape to suddenly and smoothly move downward for pasting after accumulating a certain force, and enables the adhesive tape to be pasted on the tab 103 in a relatively regular state at the appropriate time, avoiding the generation of wrinkles due to uneven force on each part of the adhesive tape during the downward pressing process, pulling or extrusion and other situations, realizing a fast and closely pasting action, and improving the efficiency of the adhesive pasting.

[0028] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
