Description

Technical Field

[0001] This utility model belongs to the field of electrode production technology, and more specifically, it relates to a fully automatic waste removal device for unwinding of a roller press. Background Technology

[0002] In modern battery manufacturing processes, especially in lithium-ion batteries, electrode coating is a crucial step. Double-sided coating technology, as the mainstream process, uniformly coats active materials onto both sides of the electrode to ensure good electrochemical performance during charging and discharging. This process typically requires high-precision coating equipment. By precisely controlling parameters such as the rotation speed of the coating rollers, the flow rate and viscosity of the slurry, a slurry containing active materials, binders, and conductive agents is evenly spread on both sides of the electrode. After coating, the electrode needs to undergo drying to remove the solvent and form a stable coating structure. It then enters the rolling process, where the coating is compacted to increase the electrode's density, meeting the battery's requirements for energy density, cycle life, and other performance indicators.

[0003] However, the current double-sided coating process faces many challenges in actual production, among which the occurrence of defective electrodes has become a major problem. Because the rolling conditions required for double-sided coated electrodes differ significantly in the subsequent rolling process, defective electrodes are highly susceptible to strip breakage when they enter the rolling stage.

[0019] The beneficial effects of the fully automatic waste rejection device for roll forming mill provided by this utility model are as follows: Compared with the prior art, the electrode sheet enters from the feeding guide roller, passes through two adhesive application components and two sets of electrode sheet displacement components, and completes double-sided adhesive application on the electrode sheet. Finally, it is conveyed to the subsequent sequence through the good product guide roller. The detection module detects the upper and lower surfaces of the electrode sheet in real time. If a problem is detected on the upper or lower surface of the electrode sheet, the electrode sheet in that area is determined to be a defective electrode sheet. At this time, the adhesive application operation stops, the front pressure belt drive and the rear pressure belt drive respectively press the defective electrode sheet, the electrode sheet cutting component cuts the defective electrode sheet, and the two sets of electrode sheet displacement components guide the defective electrode sheet to the defective product guide roller. The drive roller group guides the defective electrode sheet that has passed through the defective product guide roller into the crushing component for crushing. As the front end of the defective electrode sheet is continuously crushed until the detection module detects that the upper and lower surfaces of the electrode sheet meet the requirements, the two sets of electrode sheet displacement components guide the electrode sheet to the good product guide roller again, and the adhesive application operation starts, thereby continuously completing the double-sided adhesive application operation of the electrode sheet. This utility model provides a fully automatic waste removal device for unwinding of a roller press, which can remove defective electrode sheets, reduce the risk of belt breakage, and ensure that the roller press equipment can operate normally.

[0031] Please see Figures 1 to 3 This invention provides an automatic rejection device for unwinding waste from a roller press. The device includes a frame 1, on which a feeding detection mechanism and a double-sided adhesive applicator are sequentially mounted. A good product discharge mechanism and a waste product processing mechanism are respectively arranged on the rear side of the double-sided adhesive applicator. The feeding detection mechanism includes a feeding guide roller 4, a detection module, and a front pressure belt drive 3. The feeding guide roller 4 is rotatably mounted on the front side of the frame 1. The detection module is used to detect the upper and lower surfaces of the electrode sheets. The front pressure belt drive 3 is positioned above the feeding guide roller 4 and is used to press defective electrode sheets onto the feeding guide roller 4 when detected. The good product discharge mechanism includes a good product guide roller 11 and a rear pressure belt drive 12. The good product guide roller 11 is rotatably mounted on the rear side of the frame 1, and the rear pressure belt drive 12 is positioned above the good product guide roller 11 and is used to press defective electrode sheets onto the good product guide roller 4 when detected. The defective electrode sheet is pressed onto the good product guide roller 11. The waste processing mechanism includes a defective product guide roller 13, a drive roller group, and a crushing assembly 17. The defective product guide roller 13 is installed on the rear side of the frame 1 and located in front of the good product guide roller 11. The crushing assembly 17 is located below the defective product guide roller 13. The drive roller group is located between the defective product guide roller 13 and the crushing assembly 17 to guide the defective electrode sheet passing through the defective product guide roller 13 into the crushing assembly 17. The double-sided adhesive bonding mechanism includes two adhesive bonding assemblies arranged vertically opposite each other and two sets of electrode sheet displacement assemblies arranged vertically opposite each other. The two sets of electrode sheet displacement assemblies are located in front of and behind the two adhesive bonding assemblies, respectively. An electrode sheet cutting assembly is provided between the two sets of electrode sheet displacement assemblies. The two sets of electrode sheet displacement assemblies receive detection information from the detection module to drive the defective electrode sheet to move to the defective product guide roller 13.

[0032] The present invention provides a fully automatic waste removal device for unwinding of a roller press. Compared with the prior art, the electrode sheet enters from the feed guide roller 4, passes through two adhesive application components and two sets of electrode sheet displacement components, completes double-sided adhesive application of the electrode sheet, and finally passes through the good product guide roller 11 for subsequent transmission. The detection module monitors the upper and lower surfaces of the electrode sheet in real time. If a problem is detected on either the upper or lower surface, the electrode sheet in that area is determined to be defective. At this point, the adhesive application process stops, and the front pressure belt drive 3 and the rear pressure belt drive 12 press the defective electrode sheet firmly. The electrode sheet cutting assembly cuts the defective electrode sheet, and two sets of electrode sheet displacement assemblies guide the defective electrode sheet to the defective product guide roller 13. The drive roller group guides the defective electrode sheet that has passed through the defective product guide roller 13 into the crushing assembly 17 for crushing. As the front end of the defective electrode sheet is continuously crushed until the detection module detects that the upper and lower surfaces of the electrode sheet meet the requirements, the two sets of electrode sheet displacement assemblies guide the electrode sheet back to the good product guide roller 11, and the adhesive application process starts, thus continuously completing the double-sided adhesive application process for the electrode sheet. This utility model provides a fully automatic waste removal device for unwinding of a roller press, which can remove defective electrode sheets, reduce the risk of belt breakage, and ensure the normal production of the roller press equipment.

[0033] In practical production applications, this fully automatic waste removal device for roller presses plays a crucial role. Its precise detection and efficient removal and guiding functions significantly improve the overall quality of electrode production. Production workshop staff reported that before using this device, the mixing of defective electrodes and tape breaks were frequent occurrences, increasing production costs and severely impacting efficiency. Since adopting the device provided by this invention, defective electrodes can be identified and processed promptly and accurately, significantly reducing tape breaks on the production line. The device is also relatively easy to operate; operators only need to perform simple adjustments before starting the equipment to ensure all components are functioning correctly, requiring minimal manual intervention during production. Furthermore, the components have a long service life, resulting in relatively low maintenance costs.

[0034] Furthermore, the device is expandable. Certain components can be upgraded or adjusted to meet different production needs. For example, if the specifications of the produced electrodes change, only the electrode displacement assembly needs appropriate adjustment to adapt to the new production requirements. This flexibility allows the device to maintain good applicability in the face of constantly changing market demands, providing strong technical support for enterprises in fierce market competition.

[0035] Specifically, there are two feed guide rollers 4, arranged in a front-to-back direction, with the front feed guide roller 4 lower than the rear feed guide roller 4. The front pressure belt drive unit 3 is longitudinally positioned above the rear feed guide roller 4. Under the coordinated action of the two feed guide rollers 4, the electrode sheet can be stably fed in a predetermined direction. Since the front feed guide roller 4 is lower than the rear feed guide roller 4, the electrode sheet first passes through the lower part of the front feed guide roller 4, and then passes over the upper part of the rear feed guide roller 4, ultimately forming an overlapping feeding method where the electrode sheet overlaps with both the front and rear feed guide rollers 4.

[0036] Meanwhile, the detection module includes an upper color mark sensor 2 and a lower color mark sensor 5. The upper color mark sensor 2 is located above and in front of the rear feed guide roller 4, with its sensing end facing the upper surface of the electrode sheet that passes over the rear feed guide roller 4. The lower color mark sensor 5 is located below and behind the front feed guide roller 4, with its sensing end facing the lower surface of the electrode sheet that passes over the front feed guide roller 4. The upper color mark sensor 2 and the lower color mark sensor 5 work together to provide accurate data for subsequent production processes. For example, in the processes of electrode sheet cutting and assembly, the color mark information detected by these two sensors can ensure the accuracy of each step, avoid product quality problems caused by color mark detection errors, and greatly improve the efficiency of the entire production process and the product qualification rate.

[0037] Please see Figure 3 The drive roller assembly includes a passive drive roller 14 and an active drive roller 15 arranged sequentially. An active roller drive component 16 is fixed to the rear side of the active drive roller 15, and the active roller drive component 16 is used to drive the active drive roller 15 to rotate. The passive drive roller 14 and the active drive roller 15 clamp the defective electrode sheet between them. The active roller drive component 16 drives the active drive roller 15 to rotate, thereby continuously conveying the defective electrode sheet to the crushing assembly 17 below, ultimately achieving the purpose of continuously crushing the defective electrode sheet.

[0038] Preferably, both the passive drive roller 14 and the active drive roller 15 are coated with a layer of wear-resistant rubber. This wear-resistant rubber layer increases the friction between the rollers and the defective electrodes, ensuring that the defective electrodes do not slip during transport, thus guaranteeing the stability and continuity of the transport. Furthermore, the wear-resistant rubber layer also protects the passive drive roller 14 and the active drive roller 15, reducing direct wear on the rollers from the defective electrodes and extending the service life of the drive roller assembly. In addition, a speed adjustment device is provided on the active roller drive component 16, which allows for flexible adjustment of the rotation speed of the active drive roller 15 according to actual crushing requirements. When a large number of defective electrodes need to be processed quickly, the rotation speed can be increased, allowing the defective electrodes to be transported to the crushing assembly 17 more rapidly. Conversely, when factors such as the quality or thickness of the defective electrodes change, the rotation speed can be reduced accordingly to prevent tearing or jamming of the defective electrodes during transport.

[0039] Specifically, each electrode displacement assembly includes an upper suction cup 6 and a lower suction cup 7. The upper and lower suction cups 6 and 7 are synchronously displaced via a suction cup drive 8. The electrode is clamped between the upper and lower suction cups 6 and 7, guiding defective electrodes to the defective product guide roller 13 or qualified electrodes to the good product guide roller 11. This design plays a crucial role in the electrode production process. On one hand, the synchronous displacement of the suction cup drive 8 ensures precise cooperation between the upper and lower suction cups 6 and 7, stably clamping the electrode. When the detection system identifies a defective electrode, the upper and lower suction cups 6 and 7 will smoothly guide it to the defective product guide roller 13 according to a preset program, preventing defective electrodes from mixing with good products and ensuring overall product quality. On the other hand, for qualified electrodes, they can also accurately guide them to the good product guide roller 11, enabling the production process to proceed efficiently and orderly. Moreover, this type of electrode displacement assembly is flexible and can be adjusted appropriately according to different electrode specifications. For example, the displacement speed and clamping force of the suction cup can be changed by adjusting the parameters of the suction cup drive component 8 to adapt to diverse production needs.

[0040] Specifically, the electrode cutting assembly includes an electrode cutter 9 and a cutter drive 10. The electrode cutter 9 is located between two sets of electrode displacement assemblies and moves up and down with the help of the cutter drive 10. The cutter drive 10 can precisely control the up and down movement of the electrode cutter 9, ensuring that the cutting task is completed cleanly and efficiently without causing any unnecessary interference to the electrode displacement assemblies. During operation, when the electrode needs to be cut, the cutter drive 10 receives the instruction and quickly drives the electrode cutter 9 to move downward. The blade of the electrode cutter 9 is made of a special alloy material, which has extremely high hardness and sharpness, and can easily cut into the electrode. Moreover, the shape of the blade is carefully designed to minimize burrs on the electrode during the cutting process, ensuring that the cut electrode edge is neat and smooth. The two sets of electrode displacement assemblies maintain a stable state, providing reliable support and positioning for the cutting operation of the electrode cutter 9, ensuring that each cut is accurately performed at the predetermined position.

[0041] Please see Figures 4 to 6 The adhesive application assembly includes a crossbeam 18, a mounting frame 19, and a transverse drive 20. The crossbeam 18 is horizontally fixed to the frame 1, and the transverse drive 20 is fixed to one side of the frame 1. The transverse drive 20 is used to drive the mounting frame 19 to move along the length of the crossbeam 18. An adhesive application module for applying adhesive tape to the surface of the electrode is mounted on the mounting frame 19. The adhesive application module includes a glue supply unit, a buffer unit, a feeding unit, an adsorption unit, and a pressing unit arranged in sequence. The glue supply unit is located at one end of the mounting frame 19 for placing the tape roll. The buffer unit includes multiple upper buffer rollers 23 and multiple lower buffer rollers 24 rotatably arranged on the front side of the mounting frame 19. The multiple upper buffer rollers 23 and multiple lower buffer rollers 24 alternate. The arrangement includes an adsorption unit comprising a tape suction cup 40 and a longitudinal drive component 41. The longitudinal drive component 41 is mounted on the upper front side of the mounting frame 19, and the tape suction cup 40 is mounted on the lower end of the longitudinal drive component 41 to adsorb the tape. A pressing unit is located at the other end of the mounting frame 19 for pressing the end of the tape. The feeding unit includes a feeding plate 30, a plate drive component, a pressing assembly, and a cutting assembly. The feeding plate 30 is located on the front side of the mounting frame 19, the plate drive component is located on the rear side of the mounting frame 19, and the pressing assembly and the cutting assembly are located on the front side of the feeding plate 30. The pressing assembly is used to press or release the tape, the plate drive component drives the feeding plate 30 to move laterally, and the cutting assembly is used to cut the tape in the pressing state of the pressing unit.

[0042] The tape roll is placed on the adhesive supply unit, and the end of the tape is alternately wrapped around multiple upper buffer rollers 23 and multiple lower buffer rollers 24, extending to the pressing assembly to press the end of the tape. The lateral drive 45 drives the feed plate 30 to move laterally, passing under the tape suction cup 40 and reaching the pressing unit. The pressing unit presses the end of the tape, and the pressing assembly releases the end of the tape and returns to the initial position from under the tape suction cup 40 using the lateral drive 45. At this time, one section of the tape is located below the tape suction cup 40. The pressing assembly presses the tape again, and the cutting assembly cuts the tape under the pressing unit. The cut section of tape is adsorbed at the lower port of the tape suction cup 40. The longitudinal drive 41 drives the tape suction cup 40 to move downward, and the tape is adhered to the upper and lower surfaces of the electrode. At the same time, the transverse drive 20 drives the mounting bracket 19 to move along the length of the crossbeam 18, thereby completing the surface adhesive application operation along the entire width of the electrode. The automated adhesive application process for the electrodes increases their strength, significantly reduces the likelihood of breakage when subjected to rolling, improves production efficiency, and enhances battery quality.

[0043] The adhesive supply unit includes a tape feeder 21. A horizontally extending connecting plate 22 is provided at one end of the mounting frame 19. The tape feeder 21 is located at the end of the connecting plate 22 away from the mounting frame 19. The connecting plate 22 is fixed to one end of the mounting frame 19, and the tape feeder 21 is mounted on the end of the connecting plate 22 away from the mounting frame 19. The tape roll is placed on the tape feeder 21. When tape is needed, the tape feeder 21 can easily deliver the tape. The tape feeder 21 has a corresponding rotating structure inside, which ensures smooth rotation of the tape roll, allowing the tape to be stably extracted for use. The connecting plate 22 provides excellent connection and support, firmly connecting the tape feeder 21 to the mounting frame 19, ensuring that the tape feeder 21 does not shake or shift during operation, thus guaranteeing the continuous and efficient operation of the entire adhesive supply unit.

[0044] Please see Figures 4 to 6The buffer unit also includes a mounting top plate 25, a mounting bottom plate 26, multiple longitudinal guide columns 27, a lifting seat 28, and a first lifting cylinder 29. The mounting top plate 25 is fixed to the upper front side of the mounting frame 19, and multiple upper buffer rollers 23 are rotatably mounted side-by-side on the upper front side of the mounting top plate 25. The mounting bottom plate 26 is fixed to the lower front side of the mounting frame 19. Multiple longitudinal guide columns 27 are connected side-by-side between the mounting top plate 25 and the mounting bottom plate 26. The lifting seat 28 is slidably disposed on the multiple longitudinal guide columns 27, and multiple lower buffer rollers 24 are rotatably mounted side-by-side on the front side of the lifting seat 28. The first lifting cylinder 29 is fixed to the top of the mounting frame 19 and is used to drive the lifting seat 28 to rise and fall. When the first lifting cylinder 29 is filled with air, the gas pressure pushes the piston downward. Since the piston is connected to the lifting seat 28, the downward movement of the piston will cause the lifting seat 28 to slide downward along the multiple longitudinal guide columns 27. Conversely, when the cylinder exhausts air, the piston moves upward under external pressure, which in turn drives the lifting seat 28 to slide upward. For the buffer rollers, when the lifting seat 28 descends, multiple lower buffer rollers 24 also descend accordingly. This changes the distance between the lower buffer rollers 24 and the upper buffer rollers 23. If the lower buffer rollers 24 rise before the buffering operation begins, increasing the distance, it is easier to place the tape to be buffered between the upper and lower buffer rollers 24; while during the buffering process, the lower buffer rollers 24 descend, decreasing the distance, allowing for proper clamping or positioning of the buffered tape, ensuring the stability and accuracy of the buffering operation. Preferably, a limit bolt is vertically installed at the center of the upper end face of the mounting base 26. The limit bolt limits the downward displacement distance of the lifting seat 28. When the lifting seat 28 moves downward during operation, once its bottom contacts the top of the limit bolt, it can no longer descend. This not only effectively prevents the lifting seat 28 from collided and damaged with other components due to excessive downward movement, but also precisely controls the lowest position of the lifting seat 28 in the vertical direction. By adjusting the height of the limit bolt on the upper surface of the mounting base plate 26, the lower limit position of the lifting seat 28 can be flexibly changed to adapt to different production needs or equipment debugging requirements.

[0045] Please see Figure 4 and Figure 5The adhesive pressing unit includes a first adhesive pressing drive 42 and a first rotating arm 43. A movable plate 47 is provided on the front side of the other end of the mounting bracket 19. The first adhesive pressing drive 42 is located on the upper front side of the movable plate 47, and the first rotating arm 43 is located on the lower front side of the movable plate 47. The first rotating arm 43 is arranged laterally and rotatably connected to the movable plate 47 in the middle. The driving end of the lower part of the first adhesive pressing drive 42 is rotatably connected to the end of the first rotating arm 43 away from the tape suction cup 40. An adhesive pressing rod 46 is provided on the end of the first rotating arm 43 near the tape suction cup 40. An adjusting cylinder is provided on the rear side of the other end of the mounting bracket 19. The adjusting cylinder is used to drive the movable plate 47 to move laterally. The end of the adhesive pressing rod 46 is flat or cylindrical, which can better contact the tape and ensure that uniform pressure is applied to the tape during the adhesive pressing process. The first adhesive pressing drive 42 can be an electric push rod or a cylinder, which can precisely control the rotation amplitude of the first rotating arm 43. During the pressing operation, the driving end of the first pressing drive 42 extends, pushing the first rotating arm 43 to rotate around the central rotating mounting point, causing the pressing tape rod 46 to gradually approach the tape. The lateral adjustment cylinder 44 drives the movable plate 47 to move laterally, thereby pressing the tape rod 46 firmly against one end of the tape suction cup 40. The lateral movement of the movable plate 47 precisely controls the position of the pressing tape rod 46, ensuring a tight fit between the tape end and one end of the tape suction cup 40. After the pressing tape rod 46 contacts the tape, the first pressing drive 42 maintains a certain thrust according to the set pressure value, ensuring the tape is firmly adhered to the corresponding object surface.

[0046] Please see Figure 4 and Figure 5The feeding unit also includes a second lifting cylinder 32, which is installed on the upper front side of the feeding plate 30. A lifting plate 31 is located on the front side of the feeding plate 30, and a pressing assembly is installed on the front side of the lifting plate 31. The second lifting cylinder 32 drives the lifting plate 31 to move up and down. When the feeding plate 30 needs to pass through the tape suction cup 40 to reach the pressing unit, the second lifting cylinder 32 drives the lifting plate 31 to move downwards, thus passing over the tape suction cup 40 to reach the pressing unit. After the feeding plate 30 reaches the pressing unit, the pressing unit presses the end of the tape, and the second lifting cylinder 32 drives the lifting plate 31 to move upwards, thus adhering the tape to the lower end of the tape suction cup 40. Then, the second lifting cylinder 32 drives the lifting plate 31 downwards, returning from below the tape suction cup 40. Throughout the process, the precise control of the second lifting cylinder 32 plays a crucial role; each movement of the cylinder needs to be precisely coordinated with the operating status of the feeding plate 30 and the workflow of the pressing unit. After the tape is attached to the lower end of the tape suction cup 40, the process of the second lifting cylinder 32 driving the lifting plate 31 to move downwards and return also needs to be strictly controlled. It must ensure that the lifting plate 31 does not touch the already attached tape during its return, to avoid tape displacement or damage. At the same time, the second lifting cylinder 32 also needs to have good repeatability, because in multiple loading operations, it must accurately complete the above actions each time to ensure the continuous and stable operation of the entire loading and pressing process, thereby improving production quality and efficiency.

[0047] The pressing assembly includes a second adhesive pressing drive 33 and a second rotating arm 34. The second rotating arm 34 is horizontally positioned and rotatably mounted at the lower front side of the lifting plate 31. The second adhesive pressing drive 33 is fixed to the upper front side of the lifting plate 31, and its lower drive end is rotatably connected to the end of the second rotating arm 34 away from the tape suction cup 40. An adhesive pressing block 36 is provided at the end of the second rotating arm 34 near the tape suction cup 40, and an adhesive pressing plate 37 fixed to the lifting plate 31 is provided above the adhesive pressing block 36. When the pressing assembly starts working, the second adhesive pressing drive 33 is activated, and its drive end pushes the second rotating arm 34 to rotate around the rotatable connection point at the lower front side of the lifting plate 31. Because the second rotating arm 34 is horizontally positioned, as the drive end pushes, the adhesive pressing block 36 near the tape suction cup 40 gradually approaches the object to be pressed below. The adhesive pressing plate 37 above the adhesive pressing block 36, being fixed to the lifting plate 31, remains in a fixed position and mainly functions to press the tape. Under the action of the pressure block 36 and the pressure plate 37, the end of the tape is pulled to the pressure unit. After the pressure unit presses the end of the tape, the pressure block 36 and the pressure plate 37 separate, the entire feeding unit is reset, and the tape is pressed again by the pressure block 36 and the pressure plate 37, so that one end of the tape is located below the tape suction cup 40.

[0048] Furthermore, multiple guide rollers 35 are provided on the lower part of the front side plate of the lifting plate 31. These rollers 35 are located on the side of the second rotating arm 34 away from the belt suction cup 40 and are arranged alternately vertically. The belt is wound around these rollers 35 in an orderly manner. During the operation of the lifting plate 31, the rollers 35 play an important role in guiding the belt's direction. When the lifting plate 31 moves up and down, these rollers 35 located on the lower part of the front side plate will work in coordination with the movement of the overall structure. Because the multiple rollers 35 are arranged alternately vertically, the belt forms a winding trajectory between them, which helps to increase the stability of the belt during operation. Moreover, the design of the rollers 35 being located on the side of the second rotating arm 34 away from the belt suction cup 40 avoids possible interference with the belt suction cup 40, ensuring the normal operation of the belt suction cup 40 when adsorbing objects and the smooth transmission of the belt throughout the system, thereby ensuring the efficient operation of the entire device.

[0049] Specifically, the cutting assembly includes a cutting cylinder 38 and a tape cutter 39. The cutting cylinder 38 is fixedly mounted on the upper front side of the feeding plate 30 near the tape suction cup 40, and the tape cutter 39 is mounted on the drive end of the lower part of the cutting cylinder 38. When the feeding unit reaches the pressing unit and resets, the cutting cylinder 38 drives the tape cutter 39 to cut the tape, and the cut tape adheres to the underside of the tape suction cup 40. After the tape is cut and adhered to the underside of the tape suction cup 40, the tape suction cup 40 can move downwards with the tape to adhere to the surface of the electrode sheet. During the movement of the tape suction cup 40, the cutting assembly stops working, the cutting cylinder 38 remains stationary, and the tape cutter 39 also remains stable in its original position, waiting for the next cycle of operation between the feeding unit and the pressing unit. When a new round of operation begins, the cutting assembly will repeat the previous action, continuously providing tape of the appropriate length for the entire production process.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
