Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a diaphragm rewinding device and a diaphragm rewinding method. Background Technology

[0002] The battery cell is a crucial component of a lithium-ion battery assembly, typically consisting of a separator, electrolyte, and casing. The separator includes a positive separator and a negative separator. During charging and discharging, lithium ions move back and forth between the positive and negative separators to convert and store electrical energy. Existing separator unwinding devices generally use single-sheet unwinding, requiring replacement with new sheet material after the old sheet is used up.

[0003] In related technologies, a diaphragm roll changing device is used to switch between new and old tapes. This device includes an upper suction plate, a lower suction plate, and suction cups. New and old tapes are respectively adsorbed onto the upper and lower suction plates for cutting. The suction cups are used to hold the tape. The cut new and old tapes are then bonded together using adhesive tape on the suction cups, thus achieving the switch between new and old tapes. However, when manually changing to a new roll using this diaphragm roll changing device, the operator must follow a preset path, pulling the roll head through multiple stations on the equipment. Since the suction cups are located in the operator's blind spot, the operator must bend over to enter the equipment's working area, resulting in poor convenience and safety of the tape feeding operation, thus affecting the convenience and safety of diaphragm roll changing. Summary of the Invention

[0059] See Figure 1 , Figure 1 This illustration shows a schematic diagram of a diaphragm rewinding device according to an embodiment of this application. The device includes a first adhesive applicator module 100, a second adhesive applicator module 200, a rotating module, and a driving module 300. The first adhesive applicator module 100 includes a first adhesive preparation suction cup 1 and a first adhesive application suction cup 2. The second adhesive applicator module 200 includes a second adhesive preparation suction cup 3 and a second adhesive application suction cup 4. Both the first adhesive preparation suction cup 1 and the second adhesive preparation suction cup 3 are used to adsorb or release adhesive paper. Both the first adhesive application suction cup 2 and the second adhesive application suction cup 4 are used to adsorb... Alternatively, the material roll can be released, and the output end of the rotating module can be connected to the first adhesive suction cup 1 to drive the first adhesive suction cup 1 to rotate toward or away from the second adhesive application module 200. And / or, the output end of the rotating module can be connected to the second adhesive suction cup 3 to drive the second adhesive suction cup 3 to rotate toward or away from the first adhesive application module 100. The output end of the driving module 300 can be connected to at least one of the first adhesive application module 100 and the second adhesive application module 200 to drive the first adhesive application module 100 and the second adhesive application module 200 to move relative to each other or in opposite directions.

[0060] In one optional embodiment, the output end of the rotating module is connected to the first adhesive suction cup 1 to drive the first adhesive suction cup 1 to rotate toward or away from the second adhesive application module 200. Thus, the rotating module can drive the first adhesive suction cup 1 to rotate, facilitating the application of adhesive tape from the first adhesive suction cup 1 to the material roll.

[0061] In another optional embodiment, the output end of the rotating module is connected to the second adhesive suction cup 3 to drive the second adhesive suction cup 3 to rotate toward or away from the second adhesive application module 200. In this way, the second adhesive suction cup 3 can be driven to rotate by the rotating module, which facilitates the application of adhesive paper on the second adhesive suction cup 3 to the material roll.

[0062] In another optional embodiment, the output end of the rotating module is connected to the first adhesive suction cup 1 to drive the first adhesive suction cup 1 to rotate toward or away from the second adhesive application module 200, and the output end of the rotating module is connected to the second adhesive suction cup 3 to drive the second adhesive suction cup 3 to rotate toward or away from the second adhesive application module 200. That is, the rotating module includes a first rotating drive mechanism and a second rotating drive mechanism, the output end of the first rotating drive mechanism is connected to the first adhesive suction cup 1 to drive the first adhesive suction cup 1 to rotate toward or away from the second adhesive application module 200, and the output end of the second rotating drive mechanism is connected to the second adhesive suction cup 3 to drive the second adhesive suction cup 3 to rotate toward or away from the second adhesive application module 200.

[0063] In some embodiments of this application, the rotating module includes a rotating motor and a rotating shaft. The rotating shaft is connected to a first adhesive suction cup 1 or a second adhesive suction cup 3. When the rotating motor drives the rotating shaft to rotate, the rotating shaft drives the first adhesive suction cup 1 or the second adhesive suction cup 3 to rotate.

[0064] In some embodiments of this application, the first adhesive preparation suction cup 1, the first adhesive application suction cup 2, the second adhesive preparation suction cup 3, and the second adhesive application suction cup 4 are all provided with adsorption holes for forming negative pressure. The adhesive paper can be adsorbed onto the adsorption holes of the first adhesive preparation suction cup 1 and the second adhesive preparation suction cup 3, and the material roll can be adsorbed onto the adsorption holes of the first adhesive application suction cup 2 and the second adhesive application suction cup 4.

[0065] In some embodiments of this application, the material roll includes a first material roll and a second material roll. The first material roll is a new material roll 7, and the second material roll is an old material roll 8. The first adhesive suction cup 2 is used to adsorb or release the first material roll, or to adsorb or release the first material roll and the second material roll. The second adhesive suction cup 4 is used to adsorb or release the second material roll, or to adsorb or release the first material roll and the second material roll.

[0066] In some embodiments of this application, the first adhesive suction cup 2 and the second adhesive suction cup 4 both include a left suction cup and a right suction cup, and a cutting assembly is provided between the left suction cup and the right suction cup. When the first roll of material is adsorbed on the first adhesive suction cup 2, the first roll of material can be cut by the cutting assembly to remove excess material. When the second roll of material is adsorbed on the second adhesive suction cup 4, the second roll of material can be cut by the cutting assembly to remove excess material.

[0067] In some embodiments of this application, the first roll is a new roll 7 and the second roll is an old roll 8.

[0068] In some embodiments of this application, both the first adhesive application module 100 and the second adhesive application module 200 include an adhesive preparation component. The adhesive preparation component includes an unwinding component 9 and an adhesive pulling component 10. The unwinding component 9 is provided with adhesive paper. The adhesive pulling component 10 is used to pull one end of the adhesive paper along the length direction of the first adhesive preparation suction cup 1 so that the first adhesive preparation suction cup 1 adsorbs the adhesive paper. Alternatively, the adhesive pulling component 10 is used to pull one end of the adhesive paper along the length direction of the second adhesive preparation suction cup 3 so that the second adhesive preparation suction cup 3 adsorbs the adhesive paper.

[0069] In some embodiments of this application, the drive module 300 includes a first linear drive mechanism and a second linear drive structure. The output end of the first linear drive mechanism is connected to the first adhesive module 100 to drive the first adhesive module 100 to move toward or away from the second adhesive module 200. The output end of the second linear drive mechanism is connected to the second adhesive module 200 to drive the second adhesive module 200 to move toward or away from the first adhesive module 100.

[0070] In the aforementioned diaphragm roll changing device, when manually changing to a new roll, the first adhesive suction cup 1 can be rotated by rotating the module, so that the first adhesive suction cup 1 faces the operator. This facilitates the operator placing the roll onto the adhesive preparation assembly, thus avoiding the need for the operator to bend over and enter the equipment's working area when the first adhesive suction cup 1 is in the operator's blind spot. This improves the convenience and safety of the conveyor belt operation and the diaphragm roll changing process. Furthermore, when manually changing to a new roll, the second adhesive suction cup 3 can also be rotated by rotating the module, so that the second adhesive suction cup 3 faces the operator. This facilitates the operator placing the roll onto the adhesive preparation assembly, again avoiding the need for the operator to bend over and enter the equipment's working area when the second adhesive suction cup 3 is in the operator's blind spot. This further improves the convenience and safety of the conveyor belt operation and the diaphragm roll changing process.

[0071] Understandably, when manual guidance of the material roll is required for the wiring, the first glue-preparing suction cup 1 or the second glue-preparing suction cup 3 is rotated 90° by rotating the module to expose the suction cup position that is difficult to wire and is in the blind spot, so as to prevent personnel from entering the equipment to wire and ensure personnel safety.

[0072] Combination Figures 2 to 6 As shown, Figure 2 The left-hand figure shows a schematic diagram in an embodiment of this application where the new material roll 7 is disposed on the first adhesive application module 100 and the old material roll 8 is disposed on the second adhesive application module 200. Figure 2 The right side of the figure shows a schematic diagram of the relative movement of the first adhesive module 100 and the second adhesive module 200 in an embodiment of this application to press the new material roll 7 and the old material roll 8. Figure 3The left side of the figure shows a schematic diagram of the new material roll 7 and the old material roll 8 after being cut in an embodiment of this application. Figure 3 The right side of the figure shows a schematic diagram in which both the new material roll 7 and the old material roll 8 are adsorbed onto the second adhesive assembly in an embodiment of this application. Figure 4 The left side of the figure shows a schematic diagram of the rotating module driving the first adhesive suction cup 1 to rotate toward the second adhesive suction cup 4 in an embodiment of this application. Figure 4 The right side of the figure shows a schematic diagram of the first adhesive suction cup 1 attaching adhesive tape to the lower surface of the new material roll 7 and the old material roll 8 in an embodiment of this application. Figure 5 The left side of the figure shows a schematic diagram in which both the new material roll 7 and the old material roll 8 are adsorbed onto the first adhesive module 100 in an embodiment of this application. Figure 5 The right side of the figure shows a schematic diagram of the rotating module driving the second adhesive suction cup 3 to rotate toward the first adhesive suction cup 2 in an embodiment of this application. Figure 6 The left side of the figure shows a schematic diagram of the first adhesive module 100 and the second adhesive module 200 moving in opposite directions to separate in an embodiment of this application. Figure 6 The right-hand figure in the figure shows a schematic diagram of the relative movement of the first adhesive module 100 and the second adhesive module 200 in an embodiment of this application to remove air bubbles. Figures 2 to 6 The working process of the diaphragm changing device of this application is shown:

[0073] First, when the operator pulls the head of the new material roll 7 to the glue preparation component of the first glue application module 100, the rotating module drives the first glue preparation suction cup 1 to rotate 90°, so that the first glue preparation suction cup 1 can face the operator, making it easier for the operator to place the new material roll 7 on the first glue preparation suction cup 1. This avoids the operator having to bend over to enter the working area of ​​the equipment to operate when the first glue preparation suction cup 1 is in the operator's blind spot, thereby improving the convenience and safety of the material feeding belt operation and the convenience and safety of diaphragm roll changing.

[0074] Secondly, after the material roll is placed, the first adhesive preparation suction cup 1 resets, and the first adhesive application module 100 and the second adhesive application module 200 begin adhesive preparation. During the adhesive preparation process of the first adhesive application module 100, the unwinding component 9 first unwinds the roll, then the adhesive paper is pulled to the preset position by the adhesive pulling component 10 and cut by the cutter, and then the adhesive paper is adsorbed by the first adhesive preparation suction cup 1; during the adhesive preparation process of the second adhesive application module 200, the unwinding component 9 first unwinds the roll, then the adhesive paper is pulled to the preset position by the adhesive pulling component 10 and cut by the cutter, and then the adhesive paper is adsorbed by the second adhesive preparation suction cup 3.

[0075] After that, as Figure 2 As shown, the first adhesive suction cup 2 adsorbs the first roll of material, the second adhesive suction cup 4 adsorbs the second roll of material, and the drive module 300 drives the first adhesive module 100 and the second adhesive module 200 to move relative to each other to clamp the first roll of material and the second roll of material.

[0076] After that, as Figure 3 As shown, the first roll of material is cut by the cutting assembly of the first adhesive application module 100, and the second roll of material is cut by the cutting assembly of the second adhesive application module 200, resulting in four rolls. Then, the drive module 300 drives the first adhesive application module 100 and the second adhesive application module 200 to move in opposite directions to achieve separation. The right suction cup of the first adhesive application module 100 adsorbs the right part of the cut first roll of material, and the left suction cup of the first adhesive application module 100 releases the left part of the cut first roll of material. The left part of the first roll of material can be collected into the waste container. In the material bin; the left suction cup of the second adhesive module 200 adsorbs the left part of the cut second roll, and the right suction cup of the second adhesive module 200 releases the right part of the cut second roll. The right part of the second roll can be recycled by the reverse motion of the unwinding shaft. Then, the drive module 300 drives the first adhesive module 100 and the second adhesive module 200 to move relative to each other to clamp the first roll and the second roll. The first adhesive suction cup 2 releases the first roll, and the second adhesive suction cup 4 simultaneously adsorbs the first roll and the second roll.

[0077] After that, as Figure 4 As shown, the rotating module drives the first adhesive preparation suction cup 1 to rotate 90° toward the second adhesive application suction cup 4, so that the first adhesive preparation suction cup 1 faces the second adhesive application suction cup 4. The driving module 300 drives the first adhesive preparation suction cup 1 and the second adhesive application module 200 to move relative to each other, so as to adhere the adhesive paper to the lower surface of the first and second rolls. Then, the driving module 300 drives the first adhesive preparation suction cup 1 and the second adhesive application module 200 to move away from each other to achieve separation. The rotating module drives the first adhesive preparation suction cup 1 to rotate 90° away from the second adhesive application suction cup 4 to achieve reset. The driving module 300 drives the first adhesive application module 100 and the second adhesive application module 200 to move relative to each other to remove air bubbles in the adhesive paper.

[0078] After that, as Figure 5 As shown, the drive module 300 drives the first adhesive preparation suction cup 1 and the second adhesive application module 200 to move relative to each other to clamp the first and second rolls of material. The second adhesive application suction cup 4 releases the first and second rolls of material. The first adhesive application suction cup 2 simultaneously adsorbs the first and second rolls of material. The rotation module drives the second adhesive preparation suction cup 3 to rotate 90° toward the first adhesive application suction cup 2 so that the second adhesive preparation suction cup 3 faces the first adhesive application suction cup 2. The drive module 300 drives the second adhesive preparation suction cup 3 and the first adhesive application module 100 to move relative to each other to adhere the adhesive paper to the upper surface of the first and second rolls of material.

[0079] After that, as Figure 6As shown, the drive module 300 drives the second adhesive preparation suction cup 3 and the first adhesive application module 100 to move in opposite directions to achieve separation. The rotation module drives the second adhesive preparation suction cup 3 to rotate 90° away from the first adhesive application suction cup 2 to achieve reset. The drive module 300 drives the first adhesive application module 100 and the second adhesive application module 200 to move relative to each other to remove air bubbles in the adhesive paper, thereby realizing the diaphragm roll changing operation.

[0080] Combination Figure 7 As shown, Figure 7 The diagram shows a schematic of the first guide roller 5 and the second guide roller 6 guiding the material roll in one embodiment of this application. In some embodiments, the first adhesive module 100 further includes the first guide roller 5, which includes a first connecting frame and a first roller body. The first connecting frame and the first adhesive suction cup 2 are fixedly connected, and the first roller body and the first connecting frame are rotatably connected. The first roller body is located on one side of the first adhesive suction cup 2 and is used to support the material roll so that there is a gap between the material roll and the first adhesive suction cup 2.

[0081] It is understandable that when manually winding the material, the roll may come into contact with the adhesive suction cup prematurely, resulting in wrinkles, breakage, or other problems. This application addresses this by setting a first guide roller 5 for winding, allowing the roll to bypass and overlap the first guide roller 5, thus preventing the roll from contacting the first adhesive suction cup 2 prematurely and affecting the quality of the roll. Furthermore, during continuous unwinding, the first guide roller 5 can also adjust the tension of the roll, improving the quality of roll changing.

[0082] like Figure 7 As shown, the second adhesive application module 200 also includes a second guide roller 6. The second guide roller 6 includes a second connecting frame and a second roller body. The second connecting frame and the second adhesive application suction cup 4 are fixedly connected, and the second roller body and the second connecting frame are rotatably connected. The second roller body is located on one side of the second adhesive application suction cup 4 and is used to support the material roll, so that there is a gap between the material roll and the second adhesive application suction cup 4. With this structure, by setting the second guide roller 6 for routing, the material roll can bypass and overlap the second guide roller 6, preventing the material roll from prematurely contacting the second adhesive application suction cup 4 and affecting the quality of the material roll. Furthermore, during continuous unwinding, the second guide roller 6 can also adjust the tension of the material roll, improving the quality of roll changing.

[0083] Combination Figure 8 As shown, Figure 8 The diagram shows a schematic of the first adhesive application module 100 in one embodiment of this application. In an optional embodiment, the first adhesive suction cup 1 includes a suction cup body 13 and a driving component. The output end of the driving component is connected to the suction cup body 13 to drive the suction cup body 13 to move along a first direction, which is a direction perpendicular to the surface of the suction cup body 13. With this structure, the suction cup body 13 is driven to move along the first direction by the driving component so that the suction cup body 13 can adsorb the adhesive paper.

[0084] In another optional embodiment, the second adhesive suction cup 3 includes a suction cup body 13 and a driving component. The output end of the driving component is connected to the suction cup body 13 to drive the suction cup body 13 to move along a first direction, which is a direction perpendicular to the surface of the suction cup body 13. With this structure, the suction cup body 13 is driven to move along the first direction by the driving component so that the suction cup body 13 can adsorb adhesive paper.

[0085] In another optional embodiment, both the first adhesive suction cup 1 and the second adhesive suction cup 3 include a suction cup body 13 and a driving component. That is, the first adhesive suction cup 1 includes a first suction cup body 13 and a first driving component.

The second adhesive suction cup 3 includes a suction cup body 13 and a second driving component. The output end of the second driving component is connected to the second suction cup body 13 to drive the second suction cup body 13 to move along the first direction.

[0086] Combination Figure 9 , Figure 10 and Figure 11 As shown, Figure 9 This diagram illustrates a second adhesive module 200 according to one embodiment of the present application. Figure 10 A cross-sectional view of the second adhesive module 200 in one embodiment of this application is shown. Figure 11 A schematic diagram of the second adhesive-preparing suction cup 3 in an embodiment of this application is shown. In some embodiments, the driving assembly includes a base 11 and a piston rod 12. The base 11 has an air inlet channel 14 and a piston chamber inside. One end of the piston rod 12 is disposed in the piston chamber, and the other end of the piston rod 12 is connected to the suction cup body 13. The piston rod 12 is arranged along a first direction. The air inlet channel 14 communicates with the piston chamber and is used to introduce fluid. The fluid enters the piston chamber through the air inlet channel 14 to drive the piston rod 12 to move along the first direction. With this structure, compared with the traditional cylinder structure, this embodiment drives the suction cup body 13 to move through the piston rod 12, which makes the overall structure of the device more compact, avoids interference with other mechanical parts when exchanging diaphragms, and improves the product yield.

[0087] like Figure 10 As shown, in some embodiments of this application, the base 11 is provided with multiple piston chambers, and multiple piston rods 12 are provided, with each piston rod 12 respectively disposed in one of the multiple piston chambers. All piston rods 12 are connected to the suction cup body 13, and all piston chambers are connected to the air intake channel 14. This structure, by driving the suction cup body 13 to move through multiple piston rods 12, improves the stability and reliability of the suction cup body 13's movement.

[0088] like Figure 7As shown, in an optional embodiment, the diaphragm roll changing device further includes a rotating mechanism. The output end of the rotating mechanism is connected to the first adhesive suction cup 2 to drive the first adhesive suction cup 2 to rotate toward or away from the second adhesive module 200. With this structure, when the operator pulls the roll through the area between the first adhesive suction cup 2 and the second adhesive suction cup 4, the rotating mechanism can drive the first adhesive suction cup 2 to rotate away from the second adhesive module 200, so that the cutter assembly inside the first adhesive suction cup 2 faces the operator, improving the convenience and safety of the wiring.

[0089] In another alternative embodiment, the output end of the rotating mechanism is connected to the second adhesive suction cup 4 to drive the second adhesive suction cup 4 to rotate toward or away from the first adhesive module 100. With this structure, when the operator pulls the material roll through the area between the first adhesive suction cup 2 and the second adhesive suction cup 4, the rotating mechanism can drive the second adhesive suction cup 4 to rotate away from the first adhesive module 100, causing the cutter assembly inside the second adhesive suction cup 4 to face the operator, improving the convenience and safety of the wiring process.

[0090] In another optional embodiment, the diaphragm rewinding device further includes a rotating mechanism. The output end of the rotating mechanism is connected to the first adhesive suction cup 2 to drive the first adhesive suction cup 2 to rotate toward or away from the second adhesive module 200. The output end of the rotating mechanism is also connected to the second adhesive suction cup 4 to drive the second adhesive suction cup 4 to rotate toward or away from the first adhesive module 100. The rotating mechanism includes a first rotating mechanism and a second rotating mechanism. The output end of the first rotating mechanism is connected to the first adhesive suction cup 2 to drive the first adhesive suction cup 2 to rotate toward or away from the second adhesive module 200. The output end of the second rotating mechanism is connected to the second adhesive suction cup 4 to drive the second adhesive suction cup 4 to rotate toward or away from the first adhesive module 100.

[0091] In some embodiments of this application, the first adhesive applicator module 100 includes a first base, with the first adhesive preparation suction cup 1 and the first adhesive application suction cup 2 both mounted on the first base. The second adhesive applicator module 200 includes a second base, with the second adhesive preparation suction cup 3 and the second adhesive application suction cup 4 both mounted on the second base. The rotating module and the rotating mechanism are an integral structure and are both base rotating mechanisms. The output end of the base rotating mechanism is connected to the first base to simultaneously drive the first adhesive preparation suction cup 1 and the first adhesive application suction cup 2 to rotate, and / or, the output end of the base rotating mechanism is connected to the second base to simultaneously drive the second adhesive preparation suction cup 3 and the second adhesive application suction cup 4 to rotate. With this structure, when the first base is driven to rotate by the base rotating mechanism, the first adhesive preparation suction cup 1 and the first adhesive application suction cup 2 can be driven to rotate simultaneously. When the second base is driven to rotate by the base rotating mechanism, the second adhesive preparation suction cup 3 and the second adhesive application suction cup 4 can be driven to rotate simultaneously. This makes the structure of the diaphragm rewinding device simpler and more compact, improving the convenience of processing and installation of the diaphragm rewinding device.

[0092] In some embodiments of this application, the seat rotation mechanism may include a rotary motor and a reducer. The rotary motor is connected to the first seat or the second seat through the reducer to drive the first seat or the second seat to rotate.

[0093] It is understandable that, firstly, the cylinder transmission mechanism of the first glue suction cup 1 and the second glue suction cup 3 in this application embodiment is optimized into a piston lifting structure, eliminating the complex brackets and connectors required for cylinder installation, reducing cylinder procurement and installation costs, while simplifying the overall layout, making the structure more compact, effectively improving the utilization rate of the internal space of the equipment, and reserving space for subsequent functional expansion.

[0094] Secondly, for the scenario of manually guiding the material roll through the roller in the diaphragm unwinding process, the embodiment of this application drives the first adhesive preparation suction cup 1 and the second adhesive preparation suction cup 3 to rotate through the rotating module, and drives the first adhesive application suction cup 2 and the second adhesive application suction cup 4 to rotate through the rotating mechanism, thereby eliminating blind spots in the field of vision of each suction cup area. This eliminates the need for alignment operation when manually guiding the material roll through the roller under obstructed vision, improving the convenience of operation, and avoiding safety risks such as material roll displacement, breakage or equipment scratches caused by poor vision.

[0095] Furthermore, the first guide roller 5 and the second guide roller 6 are set at the adhesive application station. Physical limiting prevents the material roll from prematurely contacting the suction cup during the feeding process, thus avoiding wrinkles and breakage. This ensures adhesive application accuracy and unwinding stability, maintaining stable roll change quality even in high-speed production scenarios and reducing the frequency of downtime maintenance.
