Description

Technical Field

[0001] This utility model relates to the field of battery coating processing technology, and in particular to a novel elliptical battery cell coating machine structure. Background Technology

[0002] Battery cells are generally cylindrical structures with a circular cross-section. In battery production, sometimes we need to coat the cells with a protective film. Currently, only machines capable of coating circular cross-section cells are available. For elliptical cross-section cells, mechanical production is challenging because the film tube needs to be opened to a matching ellipse shape; therefore, manual coating is still used. The manual coating process is as follows: first, a standard length of film is cut; then, the battery cell is manually placed inside the film; finally, a hot air gun is used to blow the film. This manual coating method not only suffers from low efficiency, but also makes it difficult to ensure the cell is centered. Uneven film tube placement at both ends of the cell can result in uneven film distribution, affecting the final appearance of the coated cell. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel elliptical battery cell coating machine structure.

[0004] To achieve the above objectives, a novel elliptical battery cell coating machine structure is provided, comprising a frame and a pushing mechanism, a coating mechanism, a conveying mechanism, and a thermoforming mechanism arranged sequentially on the frame. A shaping mechanism is also provided below the conveying mechanism. The coating mechanism includes a coating support, on which a guide rod with an elliptical cross-section is provided. The coating support is provided with a rectangular array of clamping rollers that clamp the left and right sides of the guide rod. The coating support is provided with a rectangular array of pushing rollers that clamp the upper and lower sides of the guide rod. The coating support is also provided with a pushing drive motor that drives the pushing rollers. A cutting component is provided at the front end of the coating support. The cutting component includes a cutter and a cutting cylinder that drives the cutter to move up and down.

[0005] The battery cells are automatically coated using a push mechanism and a coating mechanism. A transport mechanism moves the cells to a shaping mechanism to adjust their relative position to the membrane tube, then to a thermoforming mechanism for heating and shaping before being transported out. The entire process is automated and highly efficient. The coating mechanism supports the membrane tube's shape using a guide rod, while a clamping roller assembly and a pushing roller assembly provide lateral and vertical support and positioning. Driving the pushing roller assembly moves the membrane tube forward. The multiple rollers prevent excessive friction from affecting the membrane tube's movement. After coating, a cutting assembly cuts the membrane tube, achieving automated coating and cutting.

[0006] Furthermore, the guide rod is provided with driven rollers that correspond to the upper and lower parts of the pusher roller assembly, and the guide rod is also provided with clearance grooves at the driven rollers. The rear end of the guide rod is provided with a guide slope that tapers towards the center.

[0007] To prevent the membrane tube from being obstructed when pushed by the membrane pusher roller assembly, a driven roller is installed on the guide rod to cooperate with the pusher roller assembly, ensuring that the membrane tube is pushed smoothly.

[0008] Furthermore, the film-covering mechanism also includes a film-covering roller disposed behind the film-covering support.

[0009] Film rollers are used to mount rolled-up film tubes.

[0010] Furthermore, the pushing mechanism includes a pushing bracket, on which a feeding conveyor belt and a feeding motor for driving its operation are provided. The pushing bracket is also provided with a pushing cylinder, the output end of which is connected to a pushing block, and a pushing rod is connected to the pushing block. The pushing rod is correspondingly arranged with the guide rod.

[0011] The feeding conveyor belt is used to transport the battery cells, and the pusher rod is used to push the battery cells into the membrane tube. The pusher rod and the guide rod are set to correspond to each other to ensure the accuracy of battery cell pushing.

[0012] Furthermore, the pusher bracket is provided with a push port at the push rod output position, and the push port is provided with a ring array of guide plates that contract towards the center on the side near the guide rod.

[0013] The guide plate retracts towards the center, facilitating its insertion into the membrane tube and ensuring precise positioning between the membrane tube and the pusher port. This ensures that the battery cell can be accurately inserted into the membrane tube once it passes through the pusher port. The guide plate is an elastic element, ensuring that the battery cell can pass freely.

[0014] Furthermore, the conveying mechanism includes a conveying bracket and a conveying belt mounted on the conveying bracket. The conveying bracket is equipped with a conveying motor that drives the conveying belt to rotate bidirectionally. The conveying belt is connected to multiple conveying components. The conveying bracket is equipped with a horizontal guide rail. Each conveying component is equipped with a slider that matches the guide rail.

[0015] The conveyor belt replaces the conveyor components for movement, while the guide rail and slider work together to ensure the accuracy and stability of the conveyor components' movement.

[0016] Furthermore, the conveying assembly includes a conveying cylinder that outputs downward and is fixedly connected to the slider, and a cylinder clamp is fixedly connected to the output end of the conveying cylinder.

[0017] Furthermore, the shaping mechanism includes a shaping double-rod cylinder mounted on the frame. The output ends of the shaping double-rod cylinder are respectively fixedly connected to clamping blocks, and the clamping blocks facing each other are respectively provided with shaping push blocks. The shaping double-rod cylinder is also fixed with a placement seat.

[0018] By ensuring equal output distances and synchronicity at the two output ends of the shaping double-rod cylinder, the clamping block is driven to extend into the membrane tube to clamp the battery cell, ensuring that the battery cell is in the center position and avoiding uneven membrane tube lengths at both ends after the battery cell is covered with membrane.

[0019] Furthermore, the thermoplastic mechanism includes a first conveying assembly and a second conveying assembly. The first conveying assembly includes a first conveyor belt and a first conveying motor that drives it to operate. The second conveying assembly includes a second conveyor belt and a second conveying cylinder that drives it to operate. The first conveying assembly also includes a thermoplastic box. The first conveying assembly is provided with a slide extending to the second conveying assembly.

[0020] The thermoforming box is placed on the first conveying assembly, where it is heated and shaped while being conveyed, improving processing efficiency. Then, it is transferred by a slide to the second conveying assembly for discharge.

[0021] Furthermore, the thermoplastic mechanism also includes a material distribution component disposed at the output end of the first conveying component. The material distribution component includes a material distribution bracket, which is provided with a discharge port. A support plate is disposed above the discharge port. A withdrawal cylinder is disposed on the material distribution bracket to drive the support plate to be withdrawn from the discharge port. A positioning double-outlet cylinder with left and right clamping is also disposed on the bracket above the support plate. The output ends of the positioning double-outlet cylinder are respectively connected to positioning blocks. The discharge port is located directly above the slide rail.

[0022] By positioning the equal output distance and synchronizing the two output ends of the dual-rod cylinder, the battery cell on the support plate is clamped and positioned, ensuring that the battery cell smoothly enters the discharge port after the positioning block is released and the support plate is removed.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This invention features a pushing mechanism, a film-coating mechanism, a transport mechanism, a shaping mechanism, and a thermoforming mechanism to sequentially push, coat, transport, shape, and thermoform the battery cell, achieving fully automated production with high efficiency. The guide rod ensures the film tube is supported to the predetermined film-coating shape. The pushing roller assembly and clamping roller assembly support and limit the guide rod. The pushing roller assembly, driven by a pushing motor, moves the film tube forward, achieving high precision and efficiency in the film-coating process. The coated film tube is then cut by a cutting assembly, ensuring orderly automated production. The shaping mechanism pushes the battery cell into position within the film tube, ensuring consistent film tube lengths at both ends of the cell. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0036] Example

[0037] like Figures 1-9 As shown, a novel elliptical battery cell coating machine structure includes a frame 1 and a pushing mechanism 2, a coating mechanism 3, a conveying mechanism 4, and a thermoforming mechanism 5 arranged sequentially on the frame 1. A shaping mechanism 6 is also provided below the conveying mechanism 3. The coating mechanism 3 pushes the membrane tube forward, the pushing mechanism 2 pushes the battery cells one by one into the membrane tube, and then the conveying mechanism 4 transports the coated battery cells to the shaping mechanism 6 for shaping. Then, the conveying mechanism 4 continues to transport the battery cells to the thermoforming mechanism 5 for heating, which causes the membrane tube to shrink and tightly wrap the battery cells for discharge.

[0038] The membrane sleeve mechanism 3 includes a membrane sleeve support 7, on which a guide rod 8 with an elliptical cross-section is provided. The guide rod 8 can support the membrane tube into a shape corresponding to the battery cell, and the cross-sectional area of ​​the guide rod 8 is larger than that of the battery cell to facilitate the insertion of the battery cell. The membrane sleeve support 7 is provided with a rectangular array of clamping rollers 9 that clamp the left and right sides of the guide rod 8. The clamping rollers 9 are provided to support and fix the guide rod 8, and the rollers are designed to reduce friction and ensure that the membrane tube wall can pass smoothly. The membrane sleeve support 7 is provided with a rectangular array of pushing rollers 10 that clamp the upper and lower sides of the guide rod 8. The membrane sleeve support 7 is also provided with a pushing roller drive motor 11 that drives the pushing rollers 10 to rotate. By driving the pushing rollers 10 to rotate, the membrane tube is moved, thereby realizing the function of automatically pushing the membrane tube. The driving connection method of the pushing rollers 10 driven by the pushing roller drive motor 11 can be implemented by any existing technology. The front end of the film-coating bracket 7 is provided with a cutting component 12, which includes a cutter 13 and a cutting cylinder 14 that drives the cutter 13 to move up and down. After the cell is coated, the cutting cylinder drives the cutter to move down and cut the film tube.

[0039] The guide rod 8 is provided with driven rollers 14 that correspond to the upper and lower parts of the pusher roller assembly 10. The membrane tube is moved by the clamping and rotation of the pusher roller assembly 10 and the driven rollers 14. The guide rod 8 is also provided with clearance grooves 15 at the driven rollers 14 to avoid direct contact and friction between the pusher roller assembly 10 and the surface of the guide rod 8. The rear end of the guide rod 8 is provided with a guide slope 16 that tapers towards the center, which facilitates the membrane tube to be fitted onto the guide rod 8 after the membrane tube is replaced.

[0040] The film covering mechanism 3 also includes a film covering roller 17 located behind the film covering bracket 7, and the film tube is rolled up and installed on the film covering roller 17.

[0041] The pushing mechanism 2 includes a pushing bracket 18, on which a feeding conveyor belt 19 and a feeding motor 20 are mounted. The battery cell is placed on the feeding conveyor belt 19 for transmission. The pushing bracket 18 is also equipped with a pushing cylinder 21. The output end of the pushing cylinder 21 is connected to a pushing block 22. The pushing block 22 is connected to a pushing rod 23. The pushing rod 23 is correspondingly arranged with the guide rod 8. After the battery cell moves to the predetermined position, the pushing rod 23 pushes the battery cell to the guide rod 8, thereby allowing it to be fitted into the membrane tube.

[0042] The pusher bracket 18 is provided with a push port 24 at the output position of the push rod 23. After the battery cell is pushed by the push rod 23, it is pushed out through the push port 24. The push port 24 is provided with a ring array of guide plates 25 that shrink towards the center on the side near the guide rod 8. After the membrane tube moves, the front end of the tube can be aligned with the push port 24 to ensure the accuracy of the battery cell film.

[0043] The conveying mechanism 4 includes a conveying bracket 26 and a conveying belt 27 mounted on the conveying bracket 26. The conveying bracket 26 is equipped with a conveying motor 28 that drives the conveying belt 27 to rotate bidirectionally. The conveying belt 27 is connected to multiple conveying components 29. The conveying belt 27 drives the conveying components 29 to clamp and move the battery cells to achieve conveying. The conveying bracket 26 is equipped with a horizontal guide rail 30. Each of the conveying components 29 is equipped with a slider 31 that matches the guide rail 30. The cooperation between the guide rail 30 and the slider 31 ensures the accuracy and stability of the conveying.

[0044] The transport assembly 29 includes a transport cylinder 32 that outputs downward and is fixedly connected to the slider 31. The output end of the transport cylinder 32 is fixedly connected to a cylinder clamp 33. The transport cylinder 32 drives the cylinder clamp 33 to move downward, and the cylinder clamp 33 clamps the battery cell.

[0045] The shaping mechanism 6 includes a shaping double-outlet cylinder 34 mounted on the frame 1. Clamping blocks 35 are fixedly connected to the output ends of the shaping double-outlet cylinder 34. Shaping push blocks 36 are respectively mounted on the opposing clamping blocks 35. A placement seat 37 is also fixed to the shaping double-outlet cylinder 34. The battery is placed on the placement seat 37 via the transport mechanism 4. The shaping double-outlet cylinder 34 drives the shaping push blocks 36 into the membrane tube to push the battery cell, ensuring the battery cell is located in the middle of the membrane tube. This prevents uneven membrane tube lengths at both ends of the battery cell after the membrane is applied. Since the membrane tube has not yet been heated and shaped, it is loosely fitted onto the battery cell, eliminating concerns about misalignment.

[0046] The thermoforming mechanism 5 includes a first conveying assembly 38 and a second conveying assembly 39. The first conveying assembly 38 includes a first conveyor belt 40 and a first conveying motor 41 that drives it. The transport mechanism 4 places the film-shaped battery cells into the first conveying assembly 38 for transport. The first conveying assembly 38 is equipped with a thermoforming box 42. During transport, the film tube shrinks and shapes due to heating in the thermoforming box 42, thereby tightly wrapping the battery cells. The second conveying assembly 39 includes a second conveyor belt 43 and a second conveying cylinder 44 that drives it. The first conveying assembly 38 is equipped with a slide 45 that extends into the second conveying assembly 39. The shaped battery cells enter the second conveying assembly 39 through the slide 45 and are transported away by the second conveying assembly 39.

[0047] The thermoplastic mechanism 5 further includes a material distribution component 46 disposed at the output end of the first conveying component 38. The material distribution component 46 includes a material distribution bracket 47, which has a discharge port 48. A support plate 49 is disposed above the discharge port 48. The end of the first conveying component 38 conveys the battery cells onto the support plate 49. The material distribution bracket 47 is equipped with a withdrawal cylinder 50 that drives the support plate 49 to withdraw from the discharge port 48. When the support plate 49 is withdrawn, the battery cells fall into the discharge port 48. To ensure... The battery cell is positioned at the center of the discharge port 48. A positioning double-outlet cylinder 51 with left and right clamping is also provided on the bracket above the support plate 49. The output ends of the positioning double-outlet cylinder 51 are respectively connected to positioning blocks 52. The positioning double-outlet cylinder 51 drives the positioning blocks 52 to clamp the battery cell, which can be used to position the battery cell. The discharge port 48 is located directly above the slide 45. After the positioning blocks 52 are released and the battery cell is pulled out, it falls from the discharge port 48 into the slide 45 and slides into the second transmission component 39.
