Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery cell production technology, specifically to a wire flattening device for battery cell production. Background Technology
[0002] The wire used in solar cell production is mainly used in the screen printing process, which is a core step in the manufacturing of photovoltaic cells. It is used to form electrode patterns on the surface of silicon wafers. With the development of the photovoltaic industry, the requirements for cell conversion efficiency and production cost are constantly increasing, which has prompted continuous progress in wire technology.
[0003] The wire flattening device for solar cell production is mainly used to straighten and flatten wires during screen printing to ensure that the wires can uniformly contact the silicon wafer surface during printing, thereby improving printing quality and efficiency. The following is a simplified structure of the device: a support plate, serving as the base of the entire device, is used to fix other components; a mounting plate, vertically fixed to the support plate, is used to mount the straightening groove plate and other components; the straightening groove plate, mounted on the mounting plate, has straightening grooves for straightening the wires; and first and second auxiliary wheels, respectively mounted on the first and second support slides on the support plate, guide the wires through the straightening groove plate. The processing flow involves the wires passing through the gap between the first and second auxiliary wheels, which apply pressure to the wires to flatten them.
[0004] Currently, most wire flattening operations on the market use eccentric rollers or irregular shafts for rolling, which is inefficient. Another structure that uses a pneumatic device for flattening is efficient enough, but the output force is not uniform enough. Pressure fluctuations can easily lead to insufficient or excessive wire deformation, which cannot guarantee the conductivity and connection accuracy during battery cell welding. Therefore, a wire flattening device for battery cell production has been designed to solve the above problems. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide a wire flattening device for battery cell production, so as to solve the technical problem that traditional devices cannot achieve both efficiency and quality.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire flattening device for battery cell production, comprising a main body, on which a pneumatic device is installed, and below the pneumatic device are several cylinder devices, the output end of the pneumatic device is connected to the input end of each cylinder device, and the output end of each cylinder device located on the bottom surface is connected to a flattening block, wherein the pneumatic device is a gas compressor.
[0007] By adopting the above technical solution, the pneumatic device drives multiple cylinder devices, which is more efficient than traditional eccentric rollers or irregular shafts for rolling. The synchronous operation of multiple cylinders ensures that the output pressure of each flattening block is uniform, solves the problem of pressure fluctuation in traditional devices, avoids insufficient or excessive deformation of the wire, and ensures the conductivity and connection accuracy of the battery cell welding.
[0008] The present invention is further configured such that a limiting shaft is connected through both sides of each of the flattened blocks.
[0009] By adopting the above technical solution, the limiting shaft guides the flattening block to move vertically and synchronously, preventing deviation during the flattening process, ensuring accurate flattening position each time, improving the consistency of multi-filament flattening, and avoiding uneven flattening caused by positional deviation.
[0010] The present invention is further configured such that a limiting block is installed at the cylinder device of the main body, and a limiting plate is provided at the bottom end of the limiting block. A plurality of damping rods are connected between the limiting plate and the limiting block, and a plurality of limiting grooves are provided at the bottom end of the limiting plate.
[0011] By adopting the above technical solution, the limiting plate is pushed by the damping rod on the limiting block to fit tightly with the wire, and the limiting groove can be adapted to the position of the wire to further fix the wire, ensuring that the flattening block acts on the designated position of the wire, improving the flattening accuracy, and ensuring the connection reliability during welding.
[0012] The present invention is further configured such that a plurality of guide shafts are rotatably connected to the bottom surface of the main body.
[0013] By adopting the above technical solution and the guide shaft rotation connection design, the friction of the thread conveying is reduced, the surface wear of the thread is prevented, and the thread is pre-guided and positioned to ensure that the position of the thread entering the flattening area is stable, which provides the prerequisite for uniform flattening and solves the flattening quality problem caused by the swaying of the thread in the traditional method.
[0014] In summary, the present invention has the following main advantages:
[0015] This invention uses a pneumatic device to drive multiple cylinders, which is more efficient than traditional eccentric rollers or irregular shafts for rolling. The synchronous action of multiple cylinders ensures uniform output pressure of the flattened block, avoiding insufficient or excessive deformation of the wires due to pressure fluctuations, and ensuring the conductivity and connection accuracy of the battery cells during welding.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0022] The embodiments of this utility model will be described below based on its overall structure.
[0023] A wire flattening device for battery cell production, such as Figure 1-4 As shown, the device includes a main body 1, on which a pneumatic device 2 is installed. Several cylinder devices 3 are installed below the pneumatic device 2. The output end of the pneumatic device 2 is connected to the input end of each cylinder device 3. Each cylinder device 3 has a flattening block 4 connected to its output end on the bottom surface. The pneumatic device 2 is a gas compressor. The pneumatic device 2 drives multiple cylinder devices 3. Compared with traditional eccentric rollers or irregular shafts for rolling, it is more efficient. Multiple cylinders work synchronously to ensure that the output pressure of each flattening block 4 is uniform, solving the pressure fluctuation problem of traditional devices, avoiding insufficient or excessive deformation of the wire, and ensuring the conductivity and connection accuracy of the battery cell welding.
[0024] Each flattening block 4 has a limiting shaft 10 connected through both sides. The limiting shaft 10 guides the flattening block 4 to move vertically, preventing it from shifting during the flattening process, ensuring accurate flattening position each time, improving the consistency of flattening multi-filament lines, and avoiding uneven flattening caused by positional deviation.
[0025] A limiting block 5 is installed at the cylinder device 3 of the main body 1, and a limiting plate 7 is provided at the bottom end of the limiting block 5. Several damping rods 6 are connected between the limiting plate 7 and the limiting block 5. Several limiting grooves 8 are opened at the bottom end of the limiting plate 7. The limiting plate 7 is pushed by the damping rods 6 on the limiting block 5 and fits tightly with the wire. The limiting grooves 8 can be adapted to the position of the wire to further fix the wire, ensure that the flattening block 4 acts on the designated position of the wire, improve the flattening accuracy, and ensure the connection reliability during welding.
[0026] Several guide shafts 9 are rotatably connected to the bottom surface of the main body 1. The rotatable connection design of the guide shafts 9 reduces the friction of the silk thread conveying and prevents the silk thread surface from being worn. At the same time, it pre-guides and positions the silk thread to ensure that the position of the silk thread entering the flattening area is stable, providing a prerequisite for uniform flattening and solving the flattening quality problem caused by the swaying of the silk thread in the traditional method.
[0027] Working principle: The pneumatic device 2 on the main body 1 drives multiple cylinder devices 3 to push the flattening block 4 to flatten the thread. The limiting shaft 10 guides the flattening block 4 to move vertically and synchronously to prevent it from shifting during the flattening process. Before this, the limiting plate 7 is pushed by the damping rod 6 on the limiting block 5 to fit tightly with the thread, and the limiting groove 8 can be adapted to the position of the thread to further fix the thread and ensure that the flattening block 4 acts on the designated position of the thread. Finally, the thread is output under the traction of the guide shaft 9.
