Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production, in particular to a high-power long strip lithium-ion battery aluminum-plastic film cutting device and a cutting method. Background Art

[0002] Aluminum-plastic film is a composite material typically made by combining aluminum foil, plastic film (such as polypropylene (PP) or polyethylene (PE), and an adhesive layer through a specialized process. It combines the barrier properties of metal with the flexibility of plastic and is widely used in food packaging, pharmaceutical packaging, lithium battery packaging, and other applications. Its main structure consists of an outer layer (protective layer): typically scratch-resistant polyester (PET) or nylon (NY), providing mechanical strength and a printable surface; a middle layer (barrier layer): aluminum foil (AL), typically 7-9 microns thick, providing excellent oxygen, water vapor, and light barrier properties; an inner layer (heat-seal layer): polypropylene (PP) or polyethylene (PE), used for heat sealing to ensure the package's tightness; and an adhesive: the layers are bonded together using polyurethane (PU) or other adhesives. It offers high barrier properties: the aluminum foil layer effectively blocks oxygen, water vapor, and UV rays, extending the shelf life of the contents. It is also lightweight: lighter than pure metal packaging, reducing costs. Its flexibility: easily processed into shapes such as bags and sheets to meet diverse packaging needs. Corrosion resistance: The inner plastic layer prevents direct contact between aluminum and the contents, avoiding chemical reactions. Heat sealing performance: The inner plastic layer is easy to bond after heating, ensuring sealing reliability.

[0003] A universal aluminum-plastic film cutting device for polymer batteries disclosed in Chinese utility model application No. 202321004313.5 has the effects of improving cutting accuracy and facilitating tool replacement, thereby improving cutting quality. However, the device has the following defects: First, the aluminum-plastic film is difficult to fix during cutting, and the cutting portion is subjected to greater pressure, which causes the cut edge to easily warp. In addition, the transmission tool generally adopts direct one-time cutting, and the cutting speed is relatively fast, which easily generates high-speed friction, causing the material to melt, thereby generating burrs, which not only affects the cutting quality, but also the molten material will adhere to the tool, affecting the use of the tool.

[0004] In Chinese utility model application No. 202023102627.8, an aluminum-plastic film cutting device for the production of lithium-ion soft-pack batteries is disclosed. Although the device has the function of improving the cutting accuracy when cutting the aluminum-plastic film, it has the following defects: after multiple cuts, due to the high thermal conductivity of aluminum, the adhesive will melt, resulting in cutting delamination, affecting the cutting quality. In addition, after cutting is completed, the parts are generally removed manually. Since the cutting edges are relatively sharp, it is easy to cause damage to the operator's hands.

[0005] Existing aluminum-plastic film cutting devices for lithium-ion batteries generally have the following defects when cutting aluminum-plastic film: delamination occurs during cutting, melted material adheres to the surface of the tool, reducing the sharpness of the tool, the cut edge is prone to warping and burrs, reducing cutting quality and cutting efficiency, and it is difficult to load and unload the material automatically. The manual labor intensity is high and it is easy to cause harm to the operator. Summary of the Invention

The sliding mounting frame 2 is rotatably connected to the outer side of the sliding seat 6, and a hand wheel 7 is installed at the end of the threaded rod 5.

[0045] The aluminum-plastic film installation mechanism consists of an aluminum-plastic film roller 40 and a conical swivel seat 4. The conical swivel seat 4 is rotatably connected to the inner wall of the mounting frame 2. A rotating roller 3 is provided inside the aluminum-plastic film roller 40. The rotating roller 3 is a frame-shaped cylindrical arrangement. The two ends of the rotating roller 3 are respectively in contact with the outer wall of the conical swivel seat 4.

[0046] The automatic feeding mechanism consists of a first motor 9, a transmission roller 10 and a transmission belt 11. The first motor 9 is installed on the outer wall of the conveying bracket 1. The output end of the first motor 9 is connected to the transmission roller 10. There are two groups of transmission rollers 10. The two groups of transmission rollers 10 span the conveying bracket 1, and the two groups of transmission rollers 10 are arranged in parallel. A transmission belt 11 is connected between the two groups of transmission rollers 10. An elastic abutment protrusion is provided on the outer surface of half the length of the transmission belt 11, and the elastic abutment protrusion is in contact with the upper surface of the conveying bracket 1.

[0047] The automatic unloading mechanism consists of a fixing frame 33 mounted on the surface of the conveying bracket 1, a transmission roller 34 mounted on the fixing frame 33, an infrared emitter 36 arranged on the fixing frame 33, an infrared receiver 37 located directly below the infrared emitter 36, and a central control display 38 arranged on the outer wall of the conveying bracket 1. The end of the transmission roller 34 is connected to a third motor 35 for transmission, and the third motor 35 is mounted on the outer wall of the fixing frame 33. The central control display 38 is conductively connected to the infrared emitter 36 and the infrared receiver 37.

[0048] An electric control box 31 is installed on the outer wall of the conveying bracket 1. The electric control box 31 is conductively connected to the electric control box 19. A plurality of control switches are provided on the electric control box 31. The automatic loading mechanism, the clamping and fixing mechanism, the automatic unloading mechanism, and the cooling mechanism are all conductively connected to the external power supply through the electric control box 19. The control switches on the electric control box 31 are conductively connected to the automatic loading mechanism, the clamping and fixing mechanism, the automatic unloading mechanism, and the cooling mechanism.

[0049] Working process: Before cutting, the aluminum-plastic film roller 40 needs to be installed on the aluminum-plastic film installation mechanism. During installation, first separate the two conical rotating seats 4 by turning the hand wheel 7, then turn the mounting frame 2 rotatably connected to the sliding seat 6, and then insert the aluminum-plastic film roller 40 onto the conical rotating seat 4, so that the inner wall of the rotating roller 3 inside the aluminum-plastic film roller 40 abuts against the outer surface of the conical rotating seat 4, and because the outer wall of the conical rotating seat 4 is conical, it can prevent the aluminum-plastic film roller 40 from rotating on the conical rotating seat 4. After the installation is completed, the end of the aluminum-plastic film roller 40 is passed around the tensioning roller 8 and placed in the automatic feeding mechanism;

[0050] When cutting the aluminum-plastic film, it is necessary to start the automatic feeding mechanism, and the transmission roller 10 is driven to rotate by the first motor 9, and the transmission roller 10 drives the transmission belt 11 to transmit, and the elastic abutment protrusion on the transmission belt 11 squeezes the aluminum-plastic film and drives the aluminum-plastic film to move. Since the elastic abutment protrusion is set halfway on the transmission belt 11, the aluminum-plastic film can move intermittently, and the length of half of the transmission belt 11 is set as the length that the aluminum-plastic film needs to be cut each time. The automatic feeding mechanism guides the end of the aluminum-plastic film onto the placement table 12, and then starts the cutting mechanism, and the electric hydraulic rod 20 on the cutting mechanism drives the knife holder 21 to move downward, so that the knife holder 21 drives the cutting tool 22 to cut the aluminum-plastic film. The cut aluminum-plastic film is moved to the collection box 32 by the automatic unloading mechanism to complete the cutting of the aluminum-plastic film. One end of the cut aluminum-plastic film is placed on one side of the transmission roller 34 of the automatic unloading mechanism. By starting the third motor 35, the third motor 35 drives the transmission roller 34 to rotate, so that the transmission roller 34 drives the cut aluminum-plastic film and guides it into the collection box 32. During the transportation, the number of aluminum-plastic films entering the collection box 32 can be counted by the infrared transmitter 36, the infrared receiver 37 and the central control display 38. The infrared transmitter 36, the infrared receiver 37 and the central control display 38 are conventional technical applications of existing infrared meters and will not be described in detail here.

[0051] Effect: When cutting the aluminum-plastic film, the device can automatically load and unload the material, and count the cut aluminum-plastic film, thereby improving the cutting efficiency and reducing manpower. In addition, the aluminum-plastic film installation mechanism can effectively limit the aluminum-plastic film roller 40 to prevent the aluminum-plastic film roller 40 from lateral displacement during rotation, thereby ensuring the stability of the aluminum-plastic film transportation and further improving the cutting quality.

[0052] For an embodiment of the present invention, please refer to Figure 2 and Figure 4The existing aluminum-plastic film cutting device requires continuous cutting, and the cutter will cause extrusion during cutting, which generates heat. Since aluminum has strong thermal conductivity, the adhesive between the aluminum and the plastic layer is easily melted, resulting in delamination, which reduces the cutting quality. Therefore, a high-power long-shaped lithium-ion battery aluminum-plastic film cutting device is provided. A water tank 13 is provided inside the placement table 12, and a circulating water pump 15 and a refrigeration box 16 are installed at the bottom of the water tank 13. A refrigeration pipe 14 is provided inside the water tank 13, and the water inlet and outlet ends of the circulating water pump 15 are both plugged into the water tank 13. A refrigeration compressor is provided inside the refrigeration box 16, and the refrigeration compressor is connected to the refrigeration pipe 14.

[0053] Working process and effects: When the aluminum-plastic film is moved to the placement table 12 through the automatic feeding mechanism, since a water tank 13 is provided inside the placement table 12 and a refrigeration pipe 14 is provided inside the water tank 13, cold water can be circulated inside the water tank 13 under the action of the circulating water pump 15, and the water temperature is uniform, so that the temperature on the surface of the placement table 12 is low, and the aluminum-plastic film is well dissipated, so that the adhesive is not easy to melt, and delamination is prevented during cutting. In addition, the low temperature can increase the brittleness of the plastic on the aluminum-plastic film to a certain extent, which is convenient for the tool to cut it better, and it is not easy to cause adhesion during cutting, further improving the cutting quality, and improving the convenience of the device during cutting.

[0054] For an embodiment of the present invention, please refer to Figures 7 to 9, when the existing aluminum-plastic film cutting device is cutting, since the aluminum-plastic film is a soft material, it is easy to warp during cutting, causing the problem of curling. In addition, when the cutting tool 22 cuts the aluminum-plastic film, the cutting tool 22 squeezes the aluminum-plastic film to generate heat, and it is difficult to dissipate heat quickly by itself, which easily causes the adhesive to melt. Moreover, the melted adhesive will stick to the surface of the cutting tool 22 during cutting, and it needs to be cleaned regularly, which is time-consuming and labor-intensive. Therefore, a high-power long strip lithium-ion battery aluminum-plastic film cutting device is provided. A clamping and fixing mechanism is installed on the fixed bracket 18. The clamping and fixing mechanism consists of a sliding seat 23, a second motor 25, a transmission screw 26 and a pressing plate 28. A through slot is provided on the fixed bracket 18, and a limit rod 24 is provided inside the through slot. The sliding seat 23 slides inside the through slot, and the sliding seat 2 3 is slidably connected to the limit rod 24, the transmission screw 26 is threadedly connected to the sliding seat 23, a fixed seat 27 is installed on the back of the fixed bracket 18, both ends of the transmission screw 26 are rotatably connected to the fixed seat 27, the bottom of the transmission screw 26 is transmission-connected to the second motor 25, a rubber pressure roller 39 is installed at the bottom of the pressing plate 28, two groups of pressing plates 28 are provided, and are symmetrically distributed on both sides of the cutting mechanism, a tool cooling mechanism is installed on the upper surface of the pressing plate 28, and the tool cooling mechanism consists of a ventilation frame 29 and a built-in ventilation fan 30, the ventilation frame 29 is installed on the upper surface of the pressing plate 28, a ventilation slot is opened on the outer wall of the ventilation frame 29, the ventilation slot is provided on one side of the cutting tool 22, the built-in ventilation fan 30 is installed on one side of the ventilation frame 29, and the built-in ventilation fan 30 is connected to the interior of the ventilation frame 29.

[0055] The working process and effect are as follows: when the aluminum-plastic film is placed on the placement table 12 and extended to the specified cutting length, the pressing and fixing mechanism is started, and the transmission screw 26 is driven to rotate by the second motor 25. The second motor 25 is a bidirectional motor. When the transmission screw 26 rotates, it drives the sliding seat 23 to move on the limit rod 24, and drives the rubber pressure roller 39 on the pressure plate 28 to move. When the rubber pressure roller 39 is squeezed onto the surface of the aluminum-plastic film, the aluminum-plastic film is fixed to prevent the aluminum-plastic film from warping during cutting. In addition, since the surface temperature of the placement table 12 is low, the brittleness of the aluminum-plastic film is increased, making it easier to cut directly.

[0056] The cutting blade 22 is then cooled and the cutting blade 22 is cooled, and the cutting blade 22 is cooled and the cutting blade 22 is cooled.
