Description

Technical Field

[0001] This utility model relates to the field of lithium battery production equipment technology, specifically to a film-applying blocking mechanism for a lithium battery production line. Background Technology

[0002] In the production of lithium batteries, a protective film is often applied to the battery surface to ensure the appearance quality and consistency of subsequent assembly. Applying the protective film is a key step in the lithium battery manufacturing process, and generally involves the following steps: 1. Feeding: The battery or battery module to be coated is fed into the coating area via a conveyor line or other transmission device; 2. Peel off the release paper: Peel off the release paper from the protective film to prepare for applying the film; 3. Precise positioning: The battery or battery module is precisely positioned at the film application location to ensure accurate film application. 4. Applying the protective film: The protective film is applied smoothly to the battery surface using a robotic arm, a bonding mechanism, or other automated equipment; 5. Pressure holding: Press the applied protective film with a certain amount of time and pressure to ensure the bonding effect.

[0003] In the above processes, precise positioning is crucial to the final quality of the film application, especially for automated production lines with high production speeds and volumes. If the pallet cannot accurately stop at the predetermined position after being transported to the film application station, the following problems can easily occur: 1. Misaligned film application: The film is not applied in the correct position, which may result in the protective film not covering the designated area, or even cause the film edges to peel up, bubbles, or wrinkles. 2. Impact on production capacity and yield: Substandard film quality requires rework or scrap, which increases production costs and reduces yield and production efficiency; 3. Poor equipment coordination: The film application process often requires coordination with robotic arms or other bonding mechanisms. If the tray positioning error is large, it will cause subsequent equipment to fail to dock properly, affecting the efficiency and stability of the overall automated process.

[0004] Therefore, a dedicated blocking and positioning mechanism is typically required at the film-applying station on the conveyor line. After the pallet arrives at the station, this mechanism can accurately position the pallet laterally or longitudinally, and also has a lifting function, ensuring a suitable spatial alignment between the pallet and the external film-applying robot, thereby achieving stability and consistency in film application. However, some blocking and positioning mechanisms currently on the market have the following shortcomings: 1. Insufficient positioning accuracy: The positioning accuracy of some blocking positioning mechanisms is insufficient to meet the requirements of high-speed automated film application process, resulting in a high film misalignment rate; 2. Complex structure and difficult maintenance: In order to take into account the functions of blocking, positioning and lifting, some existing mechanisms have overly complex mechanical structure designs, large size, many failure points, inconvenient maintenance and high cost. 3. Unstable lifting mechanism: At the film application station, the tray needs to be properly lifted to cooperate with the operation of the robotic arm. However, if the lifting structure is not designed properly, it will lead to unstable lifting or uneven force, thus affecting the film application effect. 4. Poor applicability: Different battery specifications, different tray sizes, and different film application requirements may require more flexible blocking and positioning solutions, but existing equipment generally lacks versatility.

[0005] Based on the above problems, in order to achieve universality for pallets of different specifications, and to take into account high precision, stability and ease of maintenance, this invention proposes a lithium battery production line film-applying blocking and positioning mechanism. This mechanism can accurately position the pallet after it arrives at the film-applying station, and has a lifting function so that the robot or other film-applying device can smoothly complete the film-applying operation.

Conveyor belts for conveying the lithium battery tray carrier are arranged on both sides above the fixed frame of the lifting module. The blocking module and the limiting module are arranged between the conveyor belts. The lifting module is arranged below the lithium battery tray carrier when it is at the film-applying station.

[0008] Preferably, the blocking module includes a blocking cylinder and a blocking block. The blocking cylinder is disposed on one side of the lifting module fixing frame, the cylinder rod on the blocking cylinder is connected to the blocking block, and the blocking block cooperates with one side of the lithium battery tray carrier.

[0009] Preferably, the limiting module includes a limiting cylinder and a limiting block. The limiting cylinder is located on the other side of the lifting module fixing frame. The cylinder rod of the limiting cylinder is connected to the limiting block, and the limiting block is engaged with the other side of the lithium battery tray carrier for limiting.

[0010] Preferably, the lifting module includes a lifting cylinder, a guide rod, a bushing, a reference positioning pin, and a lifting panel. The lifting cylinder is mounted on the lifting module fixing frame, and the bushings are evenly distributed around the lifting cylinder. The bushings slide with the guide rod, and the upper end of the guide rod and the cylinder rod of the lifting cylinder are connected to the lifting panel. A reference positioning pin is provided on the lifting panel, and the reference positioning pin is positioned with the lithium battery tray carrier.

The cylinder rod on the blocking cylinder 31 is connected to the blocking block 32. The blocking block 32 cooperates with one side of the lithium battery tray carrier 2.

[0016] The limiting module 4 includes a limiting cylinder 41 and a limiting block 42. The limiting cylinder 41 is located on the other side of the lifting module fixing frame 6. The cylinder rod of the limiting cylinder 41 is connected to the limiting block 42. The limiting block 42 is engaged with the other side of the lithium battery tray carrier 2 for limiting.

[0017] The lifting module 5 includes a lifting cylinder 51, a guide rod 52, a bushing 53, a reference positioning pin 54, and a lifting panel 55.

The lifting panel 55 is provided with a reference positioning pin 54, which is positioned and engaged with the lithium battery tray carrier 2.

[0018] The working principle of this specific implementation method is as follows: When the tray carrier carrying lithium batteries is transported to the film application station by the conveyor line, the blocking cylinder pushes the blocking module to move upward and lock the tray forward. At the same time, the lifting cylinder pushes the lifting panel to remove the tray carrier from the conveyor belt and fix it. Finally, it is completely fixed by the limiting cylinder at the rear.
