Description

Technical Field

[0001] The present invention relates to the technical field of battery coating, and in particular to a coating device for producing new energy batteries. Background Art

[0002] The coating device used in the production of new energy batteries is a device used to wrap insulating materials (such as blue film, PET film, etc.) on the outer surface of the battery to improve battery safety and stability.

[0003] After searching, the Chinese patent with announcement number CN212832144U discloses a novel automatic battery laminating device, including a laminating device body, a flat buffer assembly, a fixing assembly and a laminating roll. The fixing assembly is welded and fixed on the top of the laminating device body, and the laminating device body is fixedly installed with the flat buffer assembly through a bearing, and the laminating roll is installed on the fixing assembly; the fixing assembly includes a first rotating shaft, a support frame, a first connecting rod, a vertical rod, a slider, a push block, a pressure plate and a fixing groove. The top of the laminating device body is fixedly installed with a fixing groove, and the fixing groove is installed with two support frames, and the support frame is fixedly connected to one end of the first rotating shaft through a bearing. The above scheme can install laminating rolls with different inner diameters and different widths, and can also make the film pulled out of the laminating roll flat and not wrinkled, with a buffering function, and will not cause the film to rupture due to excessive tension during the laminating process, and the laminating roll is relatively convenient to install and disassemble. However, the above scheme still has the following shortcomings in actual use:

[0004] Since the ends of the film material are usually not attached to the rolled film material, although it is convenient for the staff to pull it directly, the exposed ends are prone to absorb dust in the environment, causing its viscosity to decrease. When such film material is covered on the surface of the battery, the end position is prone to edge lifting due to insufficient viscosity, affecting the coating effect and product appearance. At the same time, if the end is attached to the rolled film material, although dust pollution may be reduced, the staff will need to spend time looking for the end position, which reduces operational efficiency. This design contradiction makes it difficult for the existing device to take into account both operational convenience and protection of the film material end, thereby affecting production efficiency and coating quality.

[0005] Therefore, it is necessary to design a coating device for the production of new energy batteries to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] Reference Figures 1-12, a film coating device for the production of new energy batteries, including a bottom plate 11, a box body 12 is fixed on the bottom plate 11, an opening 121 is opened on the side of the box body 12, and a rotatable cover plate 122 is installed on the side of the box body 12, and the cover plate 122 is arranged opposite to the opening 121, and the cover plate 122 is connected to the box body 12 through a hinge. In the initial state, the cover plate 122 is in contact with the box body 12. At this time, the cover plate 122 blocks the opening 121, which can prevent dust in the environment from entering the interior of the box body 12 and protect the end position of the film material. A material roller mounting frame 13 is provided inside the box body 12, and the material roller mounting frame 13 A rolled film material is provided on the top, and two rotatable guide rollers 14 are further installed inside the box body 12, and the two guide rollers 14 are arranged to face each other up and down, and the end position of the film material passes through the gap between the two guide rollers 14. At this time, the two guide rollers 14 can provide constraints for the film material to prevent the end position of the film material from being attached to the rolled film material, thereby facilitating subsequent staff to pull the film material to extend it. In the initial state, the film material is located inside the box body 12, and the cover plate 122 blocks the opening 121. In this case, the box body 12 provides a clean placement space for the film material, which can prevent dust in the environment from adhering to the end of the film material;

[0041] This design effectively solves the problems of the film material end being easily contaminated and inconvenient to operate in the traditional laminating device. The cooperation of the box body 12 and the rotatable cover plate 122 forms a closed space in the initial state, which blocks the entry of environmental dust, protects the viscosity of the film material end, and avoids the edge lifting phenomenon during subsequent lamination. At the same time, the arrangement of the two guide rollers 14 keeps the film material end in a proper position, which neither sticks to the rolled film material and makes it difficult to find, nor is it completely exposed to the outside and contaminated by dust, making it convenient for workers to quickly locate and pull the film material. This structure effectively maintains the cleanliness and viscosity of the film material end while ensuring convenient operation, improves the lamination quality and production efficiency, and takes into account both protection and practicality.

[0042] like Figure 1 As shown, an operating table is also fixed on the bottom plate 11, and the staff places the lithium battery that needs to be coated on the operating table to facilitate the coating process of the lithium battery. A movable and rotatable pressing roller is also provided above the operating table. After the coating is completed, the staff tightly covers the film material on the surface of the lithium battery by moving the pressing roller to ensure the coating effect of the lithium battery. It should be noted that the specific operation of the lithium battery coating is an existing technology and will not be described in detail here.

[0043] The interior of the box 12 is provided with a jet assembly, which is used to generate an upward airflow to blow the end position of the film material upward. The jet assembly is composed of a jet structure and an air supply structure. The jet structure includes a jet pipe 21 and a plurality of jet heads 22. The jet pipe 21 is fixed to the interior of the box 12. The plurality of jet heads 22 are mounted on the jet pipe 21, and the plurality of jet heads 22 are distributed in a linear array. Each jet head 22 is a fan-shaped structure, thereby expanding the spray range of the jet head 22. The air supply structure includes a mounting cylinder 23, which is fixed to the bottom plate 11, and The mounting cylinder 23 is located outside the box body 12. A long strip-shaped slide is provided on the side of the mounting cylinder 23. A moving block 24 is slidably provided inside the mounting cylinder 23. An air bag 26 is also provided inside the mounting cylinder 23. One end of the air bag 26 is connected to the moving block 24, and the other end is connected to the inner surface of the mounting cylinder 23. The air bag 26 is connected to the air injection pipe 21 through an air supply pipe 27. A first magnetic block 25 is fixed to the outer circumference of the moving block 24, and the first magnetic block 25 slides in the slide. The end of the first magnetic block 25 away from the moving block 24 extends to the outside of the mounting cylinder 23.

[0044] When the first magnetic block 25 drives the moving block 24 to move, the moving block 24 can squeeze the airbag 26. When the airbag 26 is squeezed, the gas inside can enter the air injection pipe 21 through the air supply pipe 27 and finally be ejected through the plurality of air injection heads 22. The gas ejected by the plurality of air injection heads 22 can blow up the end position of the film material, so that the end film material moves upward;

[0045] The box body 12 is provided with a driving assembly, which includes a moving rod 61, a first guide seat 63 and a second guide seat 64. The first guide seat 63 is fixed to the inner top surface of the box body 12, and the second guide seat 64 is fixed to the top surface of the bottom plate 11. The moving rod 61 slides on the first guide seat 63 and the second guide seat 64. During the movement of the moving rod 61, the first guide seat 63 and the second guide seat 64 provide a limit for it. A hole is provided on the side of the box body 12, and the moving rod 61 passes through the hole and slides in the hole. A clamp 62 is fixed on one end of the moving rod 61 located inside the box body 12. The clamp 62 is made of plastic material so that the clamp 62 can undergo elastic deformation. The clamp 62 is a ring with a notch. A second magnetic block 65 is fixed on one end of the moving rod 61 located outside the box body 12, and a handle is fixed on the side of the second magnetic block 65.

[0046] When coating a lithium battery, a worker can push the movable rod 61 by the handle. In the initial stage of the movement of the movable rod 61, the second magnetic block 65 will first move to a position facing the first magnetic block 25 and attract the second magnetic block 65. At this time, the second magnetic block 65 can drive the first magnetic block 25 to move under the action of magnetic force, thereby operating the jet assembly. When the jet assembly is in operation, the gas ejected by the plurality of jet heads 22 can blow up the end position of the film material.

[0047] The box body 12 is provided with a pushing assembly, which is composed of a moving plate 31, a pressing structure and a control structure. The moving plate 31 is arranged inside the box body 12 through a sliding structure, and the moving plate 31 is located directly above the injection tube 21. A push rod 311 is fixed to the side of the moving plate 31, and the push rod 311 is arranged directly opposite the cover plate 122, which is conducive to the end position of the film material moving out of the opening 121. In addition, when the injection assembly is running, the gas blows the end position of the film material upward, so that the end position of the film material fits the bottom surface of the moving plate 31, forming a Figure 4 The status shown;

[0048] The pressing structure and the control structure are both arranged on the movable plate 31. The pressing structure includes two symmetrically arranged pressing members, which are respectively arranged on both sides of the movable plate 31. The pressing member includes a rotating shaft 32, which is rotatably mounted on the side of the movable plate 31 (such as Figure 10 As shown in FIG, a fixed sleeve 33 is fixed on the rotating shaft 32, and a connecting rod 1 35 and a connecting rod 2 37 are fixed to the outer circumference of the fixed cylinder 33. A pressure plate 34 is fixed to the end of the connecting rod 1 35 away from the fixed cylinder 33, and a push rod 36 is fixed to the end of the connecting rod 2 37 away from the fixed cylinder 33. The connecting rod 2 37 is connected to the movable plate 31 through a first tension spring 38. In the initial state, under the elastic force of the first tension spring 38, the pressure plate 34 and the movable plate 31 are in a staggered state with each other, as shown in FIG. Figure 7 and Figure 9 As shown, in this case, the pressing plate 34 will not prevent the end of the film material from being attached to the bottom surface of the movable plate 31;

[0049] The control structure includes two push plates 41 and a movable plate 44. The two push plates 41 and one movable plate 44 are slidably arranged on the top surface of the movable plate 31. The ends of the two push plates 41 that are close to each other are fixed with a cross bar 42, and the two push plates 41 are connected by a second tension spring 43. In the initial state, under the elastic force of the second tension spring 43, the two push plates 41 are in a position close to each other. At this time, the two push plates 41 and the two push rods 36 do not contact each other, and the movable plate 44 is arranged between the two push plates 41. , two inclined surfaces are provided on the movable plate 44, and the inclination directions of the two inclined surfaces are opposite, and the two cross bars 42 are respectively arranged opposite to the two inclined surfaces, and the top surface of the movable plate 44 is fixed with a vertical rod 45, and the bottom surface of the movable plate 44 is fixed with a limit block, and the top surface of the movable plate 31 is fixed with a limit rod, and the limit block is slidably sleeved on the limit rod, and the limit block is connected to one end of the limit rod by a reset spring. In the initial state, under the elastic force of the reset spring, the movable plate 44 is located away from the top rod 311;

[0050] As the movable plate 31 moves, the clamping head 62 comes into contact with the vertical rod 45 and is squeezed. During this process, the clamping head 62 is squeezed by the vertical rod 45 and deformed, and finally clamped on the vertical rod 45. When the clamping head 62 is clamped on the vertical rod 45, the clamping head 62 and the vertical rod 45 fit together, thereby ensuring the connection stability between the clamping head 62 and the vertical rod 45. In this case, the movable rod 61 can drive the vertical rod 45 to move through the clamping head 62, thereby causing the movable plate 44 to move.

[0051] When the movable plate 44 moves, the two inclined surfaces of the movable plate 44 will squeeze the two cross bars 42 respectively, so that the two cross bars 42 respectively drive the two push plates 41 to move, thereby causing the two push plates 41 to move synchronously and move away from each other. When the two push plates 41 move, they will push the two push rods 36 respectively. When the push rods 36 are pushed by the push plates 41, the push rods 36 can rotate around the rotating shaft 32 and drive the fixed cylinder 33 to rotate through the connecting rod 2 37. When the fixed cylinder 33 rotates, it can drive the pressure plate 34 to rotate through the connecting rod 1 35, and finally make the pressure plate 34 rotate around the rotating shaft 32. Therefore, when the movable plate 44 moves, the two pressure plates 34 will rotate synchronously and jointly press the end position of the film material on the bottom surface of the movable plate 31, thereby fixing the end position of the film material, forming a Figure 11 In the state shown, under the pressing action of the two pressing plates 34, the movable plate 31 can move the end position of the film material, so that the film material can be smoothly extended;

[0052] When the movable plate 44 moves to the extreme position, the thrust of the moving rod 61 can be transmitted to the movable plate 31 through the movable plate 44, so that the movable plate 44 drives the movable plate 31 to move. During the movement of the movable plate 31, the two pressure plates 34 can pull the end position of the film material to unfold the film material. Further, when the movable plate 31 moves in the direction of the cover plate 122, the top rod 311 will first contact the cover plate 122 and push the cover plate 122 to rotate the cover plate 122. When the cover plate 122 rotates, the cover plate 122 no longer blocks the opening 121, and finally the movable plate 31 and the end position of the film material move out of the opening 121. When the end position of the film material extends out of the opening 121, the staff When the movable rod 61 is released, and the movable rod 61 no longer applies a thrust to the vertical rod 45, the movable plate 44 will be reset under the elastic force of the reset spring. When the movable plate 44 is reset, the two push plates 41 will also be reset under the elastic force of the second tension spring 43, which makes the two push plates 41 no longer squeeze the two push rods 36, and the constraints of the two push plates 41 are released. The two connecting rods 37 will be reset under the elastic force of the two first tension springs 38, and finally the two pressure plates 34 will be reset. When the two pressure plates 34 are reset, the two pressure plates 34 no longer press the end position of the film material. At this time, the end position of the film material can naturally sag under the action of gravity, which is convenient for the staff to pull the end position of the film material and carry out subsequent battery coating work;

[0053] The sliding structure is composed of two sliding parts, each of which includes a side plate 51, a guide rod 55 and a guide block 56. The side plate 51 is fixed to the inner surface of the box body 12, the guide rod 55 is fixed to the side of the side plate 51, and the guide block 56 is slidably sleeved on the guide rod 55. The end of the guide block 56 away from the side plate 51 is connected to the movable plate 31. When the movable plate 31 moves, the two guide blocks 56 and the two guide rods 55 provide it with a limit to ensure the stability of the movable plate 31 during the movement process. A slot 52 is formed on the side surface of the side plate 51, and a slidable damping plate 53 is provided in the slot 52. The side surface of the damping plate 53 is in contact with the slot wall of the slot 52. The damping plate 53 and the slot wall of the slot 52 are connected by a plurality of boosting springs 54. Under the elastic force of the plurality of boosting springs 54, the damping plate 53 is always in a state of pressing the guide block 56. Under the pressure of the damping plate 53, the movable plate 31 will move only when the movable plate 31 is subjected to a thrust.

[0054] It is worth noting that before the two pressure plates 34 press the end position of the film material onto the movable plate 31, the several air jet heads 22 continue to perform air jetting action, which allows the end position of the film material to fit onto the movable plate 31 under the action of the air flow, thereby ensuring the pressing effect of the two pressure plates 34 on the end position of the film material. In addition, when the clamping head 62 pushes the vertical rod 45, the thrust exerted on the movable plate 31 is less than the friction between the two damping plates 53 and the two guide blocks 56, which makes the movable plate 31 in a stationary state and the movable plate 44 in a moving state. When the movable plate 44 moves to the extreme position, the movable plate 44 can directly apply thrust to the movable plate 31, thereby causing the movable plate 31 to overcome the friction force exerted by the two damping plates 53 on the two guide blocks 56 and move.

[0055] When the staff pulls the movable plate 31 to reset, the friction force from the two damping plates 53 cannot overcome the elastic force of the clamping head 62 itself, so that the clamping head 62 can smoothly pull the vertical rod 45, and then the vertical rod 45 drives the movable plate 44 to reset. When the movable plate 31 is reset to the initial position, the movable plate 31 cannot move further, but the movable rod 61 still keeps moving. At this time, the clamping head 62 can be deformed again and eventually detached from the vertical rod 45. When the clamping head 62 detaches from the vertical rod 45, the clamping head 62 can return to its original shape under the action of its own elastic force.

[0056] Similarly, during the resetting process of the moving rod 61, the second magnetic block 65 can be moved again to a position facing the first magnetic block 25, so that the second magnetic block 65 drives the first magnetic block 25 to be reset, and finally the moving block 24 and the airbag 26 are completely reset;

[0057] It should be noted that the material roller mounting frame 13 is provided with a function for automatically winding the film material. After a single coating is completed, the staff needs to stage the film material. In the process of pulling back the moving rod 61, the winding function will be operated and the film material will be automatically wound up, so that the film material automatically retracts to the inside of the box body 12, that is, the retraction of the film material and the resetting of the moving plate 31 are carried out synchronously until the film material and the moving plate 31 are all reset to the initial position. The automatic winding of the film material can be achieved by a motor. This is a prior art and is not shown in the figure, so it will not be described in detail here.

[0058] The working principle of the present invention is as follows:

[0059] In the initial state, the cover 122 is closed, and a closed space is formed inside the box 12 to protect the end of the film material from dust pollution. When the lithium battery needs to be coated, the staff pushes the moving rod 61 to drive the second magnetic block 65 to move, so that it adsorbs the first magnetic block 25 and pulls the moving block 24 to compress the airbag 26. The jet assembly is then started, and the fan-shaped jet head 22 blows the end of the film material upward to make it fit on the bottom surface of the moving plate 31. At the same time, the clamping head 62 at the front end of the moving rod 61 squeezes the vertical rod 45 during the movement, so that the movable plate 44 moves forward, and its inclined surface pushes the two push plates 41 away from each other, thereby driving the pressure plate 34 to rotate, pressing the end of the film material tightly on the movable plate 31. When the movable plate 44 moves to the limit position, the thrust that continues to be applied is transmitted to the movable plate 31, pushes it forward to overcome the friction of the damping plate 53, and the push rod 311 pushes open the cover plate 122, so that the end of the film material extends out from the opening 121. At this time, the moving rod 61 is released, and the reset spring returns the movable plate 44 to its original position. The pressure plate 34 releases the end of the film material under the action of the tension spring, so that it naturally droops for easy grasping. After the coating is completed, the moving rod 61 is pulled in the opposite direction, the clamping head 62 disengages from the vertical rod 45, and the second magnetic block 65 drives the first magnetic block 25 to reset, the jet assembly stops working, and the moving plate 31 slowly resets under the action of the damping plate 53, and the cover plate 122 is closed again. During the whole process, the guide roller 14 keeps the end of the film material in position, and the pressure roller ensures that the coating is tight. The synergistic effect of jetting, pressing, and pushing can not only protect the cleanliness of the film material, but also achieve rapid positioning and stable film feeding.
