Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a steel-cased battery cell bending and adhesive application mechanism. Background Technology

[0002] The flexible adhesive bonding mechanism for steel-cased battery cells is an intelligent device and a key process in battery production. It is mainly used for surface protection and insulation treatment of steel-cased battery cells, enabling automatic, precise, and efficient bonding of insulating adhesive to the surface of the steel-cased battery cells.

[0003] During the adhesive application process, to prevent the adhesive from touching the flange edge of the steel-cased battery cell (the flange structure formed by the outward folding of the top edge of the steel casing), the adhesive needs to be bent at a certain angle so that it does not come into contact with the flange edge of the steel-cased battery cell during application. However, existing adhesive application mechanisms can only automatically apply the adhesive and cannot automatically bend it. As a result, the adhesive application quality is poor when applying the adhesive flat to the steel-cased battery cell, which in turn affects the subsequent production quality of the battery. Therefore, it is necessary to design an adhesive application mechanism that can bend the adhesive at a certain angle. Utility Model Content

[0004] The purpose of this utility model is to provide a steel-shell battery cell bending and adhesive application mechanism with a reasonable structural design that ensures the quality of adhesive application.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions:

[0006] A steel-shell battery cell bending and adhesive application mechanism includes a lowering module, a fixing module, and a bending module. The lowering module is connected to a bending base, and the fixing module and bending module are respectively connected to the bending base. An arc-shaped bending guide groove is formed on the bending base, and the bending module cooperates with the bending guide groove. The lowering module moves downward with the bending base, and the fixing module and bending module follow the movement to simultaneously pick up both sides of the adhesive material. After picking up the adhesive material, the bending module can run along the bending guide groove to bend one side of the picked-up adhesive material.

[0028] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figures 1 to 4 A steel-shell battery cell bending and adhesive application mechanism includes a lowering module 100, a fixing module 200, and a bending module 300. The lowering module 100 is connected to a bending base 400, and the fixing module 200 and bending module 300 are respectively connected to the bending base 400. An arc-shaped bending guide groove 410 is provided on the bending base 400, and the bending module 300 cooperates with the bending guide groove 410. The lowering module 100 moves downward with the bending base 400, and the fixing module 200 and bending module 300 follow the movement to simultaneously pick up both sides of the adhesive material. After picking up the adhesive material, the bending module 300 can run along the bending guide groove 410 to bend one side of the picked-up adhesive material.

[0032] Specifically, in this embodiment, after the steel-cased battery cell is conveyed to the set position by the conveyor belt, the robotic arm drives the bending and adhesive application mechanism to pick up the adhesive material. The downward moving module 100 of the bending and adhesive application mechanism moves downward along with the bending base 400 connected to it. When the bending base 400 moves downward, it simultaneously drives the fixing module 200 and the bending module 300 downward. After moving to the set position, the fixing module 200 and the bending module 300 pick up the adhesive material from both sides respectively. After picking it up, the bending module 300 runs along the bending guide groove 410 of the bending base 400. When the bending module 300 is running, it bends one side of the absorbed adhesive material to a set angle (40°-50°). After bending, the robot then drives the bending and adhesive application mechanism to paste the bent adhesive material to the corresponding position of the steel-cased battery cell. Finally, the bending guide groove 410 of the bending module 300 and the bending base 400 achieves bending of the adhesive material at a certain angle, thus making the overall structure of the mechanism reasonable and effectively preventing the adhesive material from touching the flange edge of the steel-cased battery cell when it is flatly applied. This improves the quality of the adhesive material during flat application and ensures the production quality of the subsequent batteries.

[0033] Please see Figure 5 and Figure 6 To achieve bending of the rubber material, the bending module 300 in this embodiment includes a bending cylinder 310, a bending moving plate 320, a bending follower plate 330, a bending fixing head 340, and a bending fixing module 350. The bending cylinder 310 is located on the top of the bending base 400. The bending moving plate 320 is located on one side of the bending base 400 and connected to the bending cylinder 310. The bending follower plate 330 is connected to the bending moving plate 320 through a first cam follower 360, and a second cam follower 370 is provided on the bending follower plate 330. The second cam follower 370 is placed in the bending guide groove 410. The bending fixing head 340 is located on the other side of the bending base 400 and connected to the bending follower plate 330. The bending fixing module 350 is connected to the bending fixing head 340.

[0034] When the fixed module 200 and the bending module 300 simultaneously pick up the rubber material from both sides, the bending cylinder 310 drives the bending moving plate 320 to move laterally. When the bending moving plate 320 moves, it will move the bending follower plate 330 through the first cam follower 360. Since the two sets of second cam followers 370 on the bending follower plate 330 are placed in the bending guide groove 410 of the bending base 400, the bending follower plate 330 will move along the bending guide groove 410. Since the bending guide groove 410 is arc-shaped, when the bending follower plate 330 moves, it will move and turn the bending fixing head 340 connected to it at the same time, thereby causing the bending fixing module 350 connected to the bending fixing head 340 to rotate. When the bending fixing module 350 rotates, it will bend the rubber material, thereby achieving a 40°-50° bend of the rubber material.

[0035] In addition, in order to enable the bending fixing module 350 to bend the rubber material, a bending suction head 351 is provided at the lower end of the bending fixing module 350. The bending suction head 351 can vacuum suck up one side of the rubber material, and then the bending of the rubber material can be achieved by rotating the bending fixing module 350.

[0036] Since the first cam follower 360 is connected to the bending moving plate 320 and the bending follower plate 330 respectively, and the bending follower plate 330 will move along the arc-shaped bending guide groove 410, the first cam follower 360 needs to be flexibly connected to the bending moving plate 320. Therefore, a movable groove 321 is provided on the bending moving plate 320, and one end of the first cam follower 360 is placed in the movable groove 321, while the other end passes through the bending guide groove 410 and is fixedly connected to the bending follower plate 330. When the bending moving plate 320 moves laterally under the drive of the bending cylinder 310, the first cam follower 360 drives the bending follower plate 330 along the bending guide groove 410. Therefore, one end of the first cam follower 360 moves up and down in the movable groove 321 of the bending moving plate 320, so that the first cam follower 360 can drive the bending follower plate 330 to move normally. This makes the connection structure between the bending moving plate 320, the first cam follower 360 and the bending follower plate 330 reasonably designed.

[0037] Meanwhile, in order to ensure the lateral movement range of the bending moving plate 320, buffers 380 are respectively provided on both sides of the bending moving plate 320. The buffers 380 buffer and limit the movement of the bending moving plate 320 on both sides, so that the bending cylinder 310 can drive the bending moving plate 320 to move within the set range.

[0038] Please see Figure 7In this embodiment, when the bending and adhesive applicator picks up the adhesive material, the fixing module 200 and the bending module 300 simultaneously pick up both sides of the adhesive material. The bending module 300 bends the adhesive material, and after bending, the fixing module 200 pastes the picked-up adhesive material onto the corresponding position of the steel-shell battery cell. Therefore, the fixing module 200 includes a mounting block 210 and a fixing module 220. The mounting block 210 is connected to the bending base 400, and the fixing module 220 is connected to the mounting block 210. At the same time, a fixing suction head 221 is provided at the lower end of the fixing module 220. The fixing suction head 221 can pick up one side of the adhesive material, and after bending the adhesive material, the fixing suction head 221 pastes the adhesive material onto the corresponding position of the steel-shell battery cell.

[0039] Please see Figure 8 In order for the lowering module 100 to carry the fixed module 200 and the bending module 300 to pick up the rubber material, the lowering module 100 in this embodiment includes a fixed plate 110, a guide rail 120, a buffer plate 130 and a connecting plate 140. The guide rail 120 is mounted on the fixed plate 110, the buffer plate 130 is connected to the guide rail 120, and a buffer spring 150 is provided between the buffer plate 130 and the fixed plate 110. The connecting plate 140 is disposed on the buffer plate 130, and the bending base 400 is connected to the connecting plate 140.

[0040] The lowering module 100 can be driven to move downwards as a whole by a cylinder or other driving component. When the lowering module 100 moves downwards, the bending base 400 connected to the connecting plate 140 also moves downwards, thereby driving the fixing module 200 and the bending module 300 to move downwards simultaneously to pick up the adhesive from both sides. When the fixing module 200 and the bending module 300 move downwards, the buffer spring 150 between the buffer plate 130 and the fixing plate 110 can provide a certain buffering force, so that the fixing module 200 and the bending module 300 can better cooperate with the adhesive, making the adhesive picking more stable, thereby improving the picking effect and effectively protecting the bending and applying mechanism.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
