Description

Technical Field

[0001] This utility model relates to the field of battery electrode production technology, and in particular to a battery electrode coating production equipment. Background Technology

[0002] Battery electrode coating production equipment is a core piece of equipment in battery manufacturing. It is mainly used to uniformly coat electrode slurry onto the surface of metal foil current collectors to ensure the uniformity and consistency of the electrode sheets. It is also equipped with waste gas treatment and solvent recovery systems to meet the requirements of environmentally friendly production. It is widely used in the large-scale production of new energy batteries and helps to improve battery energy density and production efficiency.

[0003] However, during the processing of battery electrode coating production equipment, the electrode paste on the edge of the circuit board is prone to dripping, which not only wastes paste and contaminates the equipment, but also causes quality problems such as uneven thickness of the electrode edge and foil leakage, increases production costs, affects product consistency and production efficiency, and may even cause safety hazards due to the accumulation of dripping paste. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, the electrode paste at the edge of the circuit board is easy to drip during the processing of battery electrode coating production equipment. This not only causes paste waste and equipment pollution, but also leads to quality problems such as uneven thickness of the electrode edge and foil leakage, which increases production costs, affects product consistency and production efficiency, and may even cause safety hazards due to the accumulation of dripping paste. Therefore, a battery electrode coating production equipment is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a battery electrode coating production equipment, including a machine base and a leveling device. A frame is fixedly connected to the upper surface of the machine base, and a coating machine is fixedly installed on the surface of the frame. A transmission belt is sleeved on the surface of the machine base. The leveling device is set on the surface of the machine base and includes a fixing block. The fixing block is fixedly connected to the machine base, and a cylinder is fixedly connected to the surface of the fixing block. The driving end of the cylinder passes through the fixing block and is fixedly connected to a clamping plate. A guide rail is fixedly connected to the surface of the clamping plate, and a sliding plate is slidably connected to the surface of the guide rail. A push plate is fixedly connected to the lower surface of the sliding plate, and a threaded rod is rotatably connected to the surface of the clamping plate. By setting up the leveling device, a servo motor drives the threaded rod to cooperate with the sliding plate, driving the push plate to scrape off and level the excess electrode paste on both sides of the circuit board. This can effectively reduce problems such as uneven edge thickness and dripping caused by paste accumulation, improve the flatness and consistency of electrode coating, ensure product quality, reduce subsequent processing difficulties caused by uneven paste, improve production efficiency, and reduce defect rate.

[0006] Preferably, the surface of the slide plate is provided with a threaded hole, the threaded rod is threadedly connected to the slide plate, a servo motor is fixedly connected to one side of the clamping plate, and the drive end of the servo motor is fixedly connected to the threaded rod. By setting the slide plate, when the servo motor drives the threaded rod to rotate, the slide plate moves in a preset direction through the threaded engagement with the threaded rod, ensuring that the push plate can scrape off excess paste from the edge of the circuit board at a uniform speed and stably.

[0007] Preferably, there are two clamping plates, which are symmetrically arranged. By setting the clamping plates, the circuit board is stably clamped, ensuring that the position of the circuit board is fixed during the coating and flattening process, and avoiding uneven coating or dripping of the slurry due to shaking.

[0008] Preferably, the clamping plate is located below the coating machine, and the longitudinal section of the push plate is L-shaped. By setting the push plate, after the coating is completed, the servo motor drives the threaded rod to rotate, and the threaded engagement drives the slide plate to move laterally. The slide plate then pushes the push plate to move along the edge of the circuit board. The edge of the push plate is in contact with the surface of the circuit board, which can evenly scrape off the slurry accumulated on the edge.

[0009] Preferably, a recycling component is provided on one side of the clamping plate. The recycling component includes a rod, which is fixedly connected to the clamping plate. A box is provided on one side of the rod, and a hanging plate is fixedly connected to the upper surface of the box. By setting up the recycling component, during the flattening process of the push plate, excess electrode paste is squeezed into the box. Through the easy disassembly structure of the hanging plate and the rod, the box can be easily and quickly removed, realizing the recycling of electrode paste waste. This not only reduces paste waste and lowers production costs, but also reduces the pollution of equipment caused by waste accumulation, keeps the production environment clean, and facilitates equipment maintenance.

[0010] Preferably, the surface of the hanging plate has insertion holes, and the insertion rod is inserted into the insertion holes on the surface of the hanging plate.

[0011] Preferably, the hanging plate is L-shaped, and the height of the box is lower than that of the push plate. By setting the box, when the leveling device scrapes off excess slurry from the edge of the circuit board, the waste is squeezed into the box by the push plate. The box is fixedly installed by the cooperation of the hanging plate and the plug rod. When the box is full of waste, it can be quickly disassembled by simply pulling the hanging plate away from the plug rod, which is convenient for centralized cleaning or recycling, avoids slurry dripping and contaminating the equipment, and avoids waste. At the same time, it keeps the production environment clean and improves the efficiency of waste treatment.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

In this utility model, by setting a leveling device, during use, the transmission belt drives the circuit board to the bottom of the coating machine, and then the cylinder drives the clamping plate to clamp the two sides of the circuit board. Subsequently, the surface of the circuit board on the coating machine is coated. After the coating is completed, the servo motor drives the threaded rod to rotate. While the threaded rod rotates, it moves in conjunction with the sliding plate. While the sliding plate moves, it drives the push plate. The push plate scrapes off and flattens the excess electrode paste on both sides of the circuit board. By setting a leveling device, the servo motor drives the threaded rod and the sliding plate to work together to drive the push plate to scrape off and flatten the excess electrode paste on both sides of the circuit board. This can effectively reduce problems such as uneven edge thickness and dripping caused by paste accumulation, improve the flatness and consistency of electrode coating, ensure product quality, reduce subsequent processing difficulties caused by uneven paste, improve production efficiency, and reduce defect rate.

[0014] 2. In this utility model, by setting up a recycling component, during the process of the pusher plate moving and leveling, excess electrode slurry is squeezed and pushed into the box. By pulling the hanging plate away from the insert rod, the box can be removed, facilitating the recycling of electrode slurry waste.

[0022] In this implementation scheme: the leveling device 5 includes a fixed block 51, which is fixedly connected to the machine base 1. A cylinder 52 is fixedly connected to the surface of the fixed block 51. The driving end of the cylinder 52 passes through the fixed block 51 and is fixedly connected to a clamping plate 53. A guide rail 54 is fixedly connected to the surface of the clamping plate 53. A slide plate 59 is slidably connected to the surface of the guide rail 54. A push plate 58 is fixedly connected to the lower surface of the slide plate 59. A threaded rod 56 is rotatably connected to the surface of the clamping plate 53. By setting up the leveling device 5, the servo motor 57 drives the threaded rod 56 to cooperate with the slide plate 59, thereby driving the push plate 58 to scrape off and level the excess electrode paste on both sides of the circuit board. This can effectively reduce the problems of uneven edge thickness and dripping caused by paste accumulation, improve the flatness and consistency of electrode coating, ensure product quality, reduce subsequent processing difficulties caused by uneven paste, improve production efficiency, and reduce defect rate.

[0023] Specifically, the surface of the slide plate 59 is provided with threaded holes, and the threaded rod 56 is threadedly connected to the slide plate 59. A servo motor 57 is fixedly connected to one side of the clamping plate 53. The drive end of the servo motor 57 is fixedly connected to the threaded rod 56. By setting the slide plate 59, when the servo motor 57 drives the threaded rod 56 to rotate, the slide plate 59 moves along a preset direction through the threaded engagement with the threaded rod 56, ensuring that the push plate 58 can scrape off excess paste from the edge of the circuit board at a uniform speed and stably.

[0024] Specifically, there are two clamping plates 53, which are symmetrically arranged. By setting the clamping plates 53, the circuit board is stably clamped, ensuring that the position of the circuit board is fixed during the coating and flattening process, and avoiding uneven coating or dripping of the paste due to shaking.

[0025] Specifically, the clamping plate 53 is located below the coating machine 3, and the longitudinal section of the push plate 58 is set in an "L" shape. By setting the push plate 58, after the coating is completed, the servo motor 57 drives the threaded rod 56 to rotate, and through the threaded engagement, it drives the slide plate 59 to move laterally. The slide plate 59 then pushes the push plate 58 to move along the edge of the circuit board.

A box body 551 is provided on one side of the plug rod 553, and a hanging plate 552 is fixedly connected to the upper surface of the box body 551.

The box 551 is fixedly installed by the cooperation of the hanging plate 552 and the plug rod 553. When the box 551 is full of waste, it can be quickly disassembled by simply pulling the hanging plate 552 away from the plug rod 553, which is convenient for centralized cleaning or recycling and reuse, avoiding slurry dripping and contaminating the equipment and causing waste, while keeping the production environment clean and improving the waste treatment efficiency.

Then, the cylinder 52 drives the clamping plate 53 to clamp the two sides of the circuit board. Subsequently, the coating machine 3 coats the surface of the circuit board. After the coating is completed, the servo motor 57 drives the threaded rod 56 to rotate. While the threaded rod 56 rotates, it moves in conjunction with the sliding plate 59. As the sliding plate 59 moves, it drives the push plate 58. The push plate 58 scrapes away and flattens the excess electrode paste on both sides of the circuit board. By setting up the leveling device 5, the servo motor 57 drives the threaded rod 56 and the sliding plate 59 to drive the push plate 58 to scrape away and flatten the excess electrode paste on both sides of the circuit board.
