Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to a laser cutting device for battery processing. Background Technology

[0002] Electrode sheets are the core energy storage components of lithium-ion batteries, directly determining the battery's energy density, cycle life, and safety performance. They are divided into positive electrodes (aluminum foil substrate) and negative electrodes (copper foil substrate), both of which are made by coating thin metal foil substrates with active materials and then processing them. In the mass production process of batteries, electrode sheets need to be precisely cut from continuous master rolls into single electrode sheets of preset sizes. Laser cutting has become the mainstream technology for electrode sheet cutting due to its advantages such as high cutting precision, small heat-affected zone, and suitability for thin material processing.

[0003] Although laser cutting is widely used, existing cutting equipment still has significant shortcomings. On the one hand, the coordination of various functional components is poor. Laser cutting, electrode separation, guiding, flattening, and mother roll cleaning are mostly controlled independently, making it difficult to accurately match the timing of actions. This can easily lead to problems such as electrode adhesion to the mother roll and edge tearing after cutting due to electrostatic adsorption and material stickiness. Furthermore, thin electrode blanking is prone to edge warping and wrinkles, affecting the neatness of subsequent assembly. An overall automated closed loop has not been formed, and some steps require manual intervention and adjustment, resulting in fragmented operation and making it difficult to meet the high requirements of processing efficiency and product consistency for mass production. Summary of the Invention

[0011] Preferably, the cleaning component includes two connecting rods two that are fixedly connected to the upper end of the flattening component. The outer surfaces of the two connecting rods two are slidably connected to the fixed base one. The ends of the two connecting rods two away from the connecting base are fixedly connected to a squeezing plate two. The front end of the squeezing plate two is fixedly connected to a rack.

[0012] Preferably, a fixed base two is fixedly connected to the upper end of the processing table, and adjustment grooves are provided at both the front and rear ends of the fixed base two.

[0013] Preferably, a wiping roller is rotatably connected to the inner surface of the second fixed base.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention forms a complete processing closed loop through the cooperation of various components. After the laser cutting machine completes the cutting, the flattening component, air blowing component, and cleaning component enter a preset working mode, enabling fully intelligent operation without manual intervention. The air blowing component ensures rapid and damage-free separation of the electrode sheet from the mother roll, while the flattening component smooths the electrode sheet in real time during its descent, preventing defects such as tearing, rolling, and warping / wrinkling at the source. Simultaneously, the cleaning component can intermittently control the spray volume and wiping frequency of isopropyl alcohol, performing adaptive pre-cleaning of the mother roll, ensuring cleaning effectiveness while avoiding media waste. The entire process relies on intelligent linkage control, breaking away from the fragmented operations of manual separation, flattening, and cleaning after cutting in traditional processing. It achieves intelligent connection and autonomous operation of the entire process from cutting to separation, flattening, and cleaning, significantly shortening the processing cycle. Furthermore, by intelligently adapting to the processing needs of different electrode sheet specifications and automatically optimizing process parameters, it significantly improves the consistency and efficiency of mass production, fully demonstrating the precision, adaptability, and efficiency of intelligent processing.

[0015] This invention utilizes a combination of opening and closing components, a flattening component, a laser cutter, an air blowing component, and a cleaning component to create a fully automated closed-loop process for cleaning, cutting, separating, guiding, flattening, and collecting electrode sheets. The air blowing component smoothly blows the cut electrode sheets into the feed inlet, allowing them to detach smoothly from the mother roll. Simultaneously, the flattening component, under intelligent linkage, adjusts the speed of the flattening drum, allowing the electrode sheets to enter between two flattening drums and flatten the raised edges during their descent, ensuring the uniformity of subsequent collection. During this process, the extrusion plate and the water bladder are simultaneously driven, intelligently controlling the timing and frequency of isopropyl alcohol spraying based on the mother roll conveying rhythm. This ensures precise and intermittent spraying of isopropyl alcohol onto the wiping roller, driving the wiping roller to clean the mother roll surface in advance. This intelligent linkage process reduces the impact of impurities on the mother roll surface on subsequent cutting and separation, effectively lowering the defect rate caused by misalignment or coordination deviations in a single step, further improving the consistency of the final product. The entire process requires no manual intervention, upgrading the original automated process to a more precise and stable intelligent collaborative processing mode. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Example 1, as Figure 1-2As shown, a laser cutting device for battery processing includes a processing table 1. Support bases 11 are fixedly connected to both ends of the processing table 1. Rotary rollers 12 are rotatably connected to the inner surfaces of the two support bases 11. A laser cutting machine 4 for cutting electrode sheets is installed on the upper end of the processing table 1. An opening and closing assembly 2 for easy unloading is provided on the right side of the laser cutting machine 4. A flattening assembly 3 for preventing the electrode sheets from warping is provided at the lower end of the opening and closing assembly 2. An air blowing assembly 5 for eliminating static electricity is installed on the right side of the laser cutting machine 4. A cleaning assembly 6 for wiping the surface of the electrode sheets is provided on the left side of the opening and closing assembly 2.

[0020] The laser cutting machine 4 mentioned above is existing technology. Its working principle is as follows: First, the laser converts electrical energy into a laser beam of a specific wavelength. Adaptive parameters are selected based on the electrode material. The laser beam is guided and transmitted through a reflector and collimating lens in the optical path system to ensure beam collimation and energy stability. Then, it is focused onto an extremely small spot by a focusing lens group, forming an extremely high power density on the electrode surface. Since the electrode is a composite structure of a coating and a metal current collector, the coating material has high laser absorption and low thermal conductivity, while the metal current collector has strong reflectivity and fast thermal conductivity. The focused laser can rapidly heat the coating to its melting or vaporization temperature, while the metal current collector undergoes ablation under high power density, forming micro-holes. As the laser spot moves along a preset trajectory, continuous holes form a narrow kerf. During the cutting process, coaxially sprayed auxiliary gas can blow away slag, prevent oxidation of the cut, and simultaneously cool the material and optical lenses, reducing the heat-affected zone. The CNC system coordinates parameters such as laser power and spot movement speed in real time according to the cutting trajectory parameters to ensure cutting accuracy. The entire process adapts the physical properties of different layers of electrode material through parameter matching, achieving contactless and low-loss high-precision cutting, which meets the strict requirements of power battery electrode sheets for dimensional accuracy and surface quality. The above are all conventional technical fields, so they will not be described in detail in this solution.

[0021] Furthermore, the rotating spool 12 at the right end is connected to an external power source, which can pull the entire electrode sheet roll for transport during rotation.

[0022] In the operation of this embodiment, a complete processing closed loop is formed through the cooperation of various components. After the laser cutting machine 4 finishes cutting, the opening and closing component 2 simultaneously triggers the flattening component 3, the air blowing component 5, and the cleaning component 6, so that the cut electrode sheet and the mother roll are quickly separated under the drive of the air blowing component 5 and enter the flattening component 3 for smoothing. This achieves real-time flattening during the downward movement of the electrode sheet, avoiding defects such as tearing, rolling, and warping wrinkles during the separation process of the electrode sheet. At the same time, the cleaning component 6 sprays isopropyl alcohol on the surface of the electrode sheet mother roll to complete the pre-cleaning of the mother roll. The entire process does not require manual intervention, and each link is seamlessly connected. This avoids the fragmented operation of manual separation after cutting, followed by separate flattening and cleaning in traditional processing, which greatly shortens the processing cycle and improves the efficiency of mass production.

[0023] Example 2, as Figure 1-10 The opening and closing assembly 2 includes a fixed base 21 fixedly connected to the upper end of the processing table 1. A hydraulic device 22 is fixedly installed on the upper end of the fixed base 21. A connecting base 23 is fixedly connected to the output end of the hydraulic device 22. Two connecting rods 24 are rotatably connected to the inner surface of the connecting base 23. A sliding block 25 is rotatably connected to the lower end of each of the two connecting rods 24. A processing seat 26 is fixedly connected to the upper end of the processing table 1. A feeding port 261 is opened on the outer surface of the processing seat 26.

[0024] The lower end of the discharge port 261 is an inclined surface. The upper ends of the two sliding blocks 25 are fixedly connected to the opening and closing plates 27. The lower ends of the two opening and closing plates 27 are slidably connected to the processing base 26. The lower end of the processing table 1 is fixedly connected to the storage box 28.

[0025] Furthermore, after the laser cutting machine 4 finishes cutting an electrode sheet, the hydraulic device 22 is activated to drive the connecting seat 23 to descend. The connecting seat 23 will push the sliding blocks 25 on both sides to open, so that the sliding blocks 25 drive the two opening and closing plates 27 to open, revealing the material outlet 261 below.

[0026] The flattening assembly 3 includes a through groove 31 at the upper end of the processing table 1, which corresponds to the lower end of the feeding port 261. Two smoothing cylinders 32 are rotatably connected to the inner surface of the through groove 31. Sliding grooves 33 are provided on both the front and rear sides of the upper end of the processing table 1. Sliding blocks 34 are fixedly connected to the lower ends of the two sliding blocks 25. The two sliding blocks 34 are slidably connected to the sliding grooves 33 on the same side. Sliding grooves 35 are provided on the right side of the two sliding grooves 33. Rotating rods 36 are rotatably connected to the front ends of the two smoothing cylinders 32.

[0027] The outer surface of the rotating rod 36 on the left is provided with a guide groove 361. The right end of the sliding block 34 is fixedly connected to a guide rod 341. The outer surface of the guide rod 341 is slidably connected to the guide groove 361. The outer surfaces of the two rotating rods 36 are fixedly connected to gears 37, and the two gears 37 are meshed with each other.

[0028] The guide groove 361 mentioned above is composed of a straight line and a spiral track; Furthermore, when the two sliding blocks 25 open outwards simultaneously, they will move the sliding block 34 together, causing the guide rod 341 to begin sliding in the guide groove 361. When the guide rod 341 slides to the connection between the straight line and the threaded track, the two opening and closing plates 27 have also opened, and the electrode pieces cut on their surfaces will fall into the feed port 261 and enter the through groove 31 along the inclined surface.

[0029] Synchronously, the sliding block 34 continues to move outward. When the guide rod 341 enters the spiral groove of the guide groove 361, the rotating rod 36 begins to rotate and drives the other rotating rod 36 to rotate together through the gear 37. The two rotate towards the middle at the same time, so that the electrode sheet can pass through the middle of the two rotating rods 36 and be pressed. Among them, the two smoothing rollers 32 are preferably made of modified silicone material with added antistatic agent to ensure that the smoothing rollers 32 have good static electricity discharge capability, avoiding the problem of the electrode sheet being attracted and shifted, stuck or even warped again by static electricity during the smoothing process. At the same time, they can also closely fit the warped part of the electrode sheet and apply uniform pressure. The pressure will offset the warping stress, forcing the edge of the electrode sheet to return to flatness from the bent state, gradually smoothing the warped edge, and avoiding excessive local pressure that could cause the electrode sheet to deform.

[0030] The air blowing assembly 5 includes a jet pipe 51 fixedly connected to the lower end of the connecting seat 23, a connecting pipe 52 fixedly connected to the right end of the connecting seat 23, a left end of the connecting pipe 52 fixedly connected to the jet pipe 51, two extrusion plates 53 fixedly connected to the right end of the connecting pipe 52, and two air bags 54 fixedly connected to the upper end of the processing table 1. The upper ends of the two air bags 54 are fixedly connected to the extrusion plates 53 on the same side.

[0031] Furthermore, each of the two airbags 54 mentioned above is equipped with two one-way valves. One of them corresponds to the lower end of the connecting pipe 52 on the same side. When the airbag 54 is squeezed, the internal air pressure increases, and the gas will overflow from the one-way valve, pass through the connecting pipe 52, and finally be ejected from the jet pipe 51. It can only expel air outward and cannot take in air. The other one is located on the rear side of the connecting pipe 52. When the compression plate 53 rises, it pulls the airbag 54 to enlarge it, making its internal air pressure decrease. It draws in air from the one-way valve to fill the gas inside the airbag 54. It can only take in air inward and cannot expel air outward.

[0032] When the connecting seat 23 is pressed down to open the two opening plates 27 outward, the airbag 54 is also squeezed at the same time. The gas passes through the connecting pipe 52 and is ejected from the jet pipe 51, blowing towards the cut electrode sheet. This quickly breaks the adsorption force between the electrode sheet and the mother roll, such as electrostatic adsorption or slight adhesion, ensuring that the electrode sheet is completely separated from the mother roll, so that the electrode sheet can smoothly enter the feeding port 261.

[0033] The cleaning component 6 includes two connecting rods 61 fixedly connected to the upper end of the flattening component 3. The outer surfaces of the two connecting rods 61 are slidably connected to the fixed base 21. The ends of the two connecting rods 61 away from the connecting base 23 are fixedly connected to the extrusion plate 62. The front end of the extrusion plate 62 is fixedly connected to the rack 63.

[0034] The upper end of the processing table 1 is fixedly connected to a fixed base 64. The front and rear ends of the fixed base 64 are provided with adjustment grooves 641. The upper end of the fixed base 64 is fixedly connected to a protective shell 65. A water bladder 66 is provided inside the protective shell 65. The lower end of the extrusion plate 62 is movably connected to the water bladder 66. Several water spray pipes 67 are fixedly connected to the lower end of the water bladder 66.

[0035] One-way valves are installed at the connection between the water bladder 66 and the water spray pipe 67. These one-way valves can only spray water outwards. When the second extrusion plate 62 descends and extrudes the water bladder 66, the water pressure inside the water bladder 66 increases and overflows from the water spray pipe 67, causing the isopropanol inside the water bladder 66 to be sprayed intermittently onto the surface of the wiping roller 68. This avoids waste caused by continuous spraying of isopropanol and reduces the impact of excessive alcohol on the active material of the electrode sheet.

[0036] The isopropanol mentioned above can quickly dissolve oil, cutting residue dust and other contaminants on the surface of the electrode sheet, ensuring the cleanliness of the electrode sheet to improve the subsequent assembly bonding. It evaporates quickly without residue, avoiding contaminants or residual solvents from affecting the battery's charging and discharging performance. At the same time, its chemical properties are mild and will not corrode the active material coating of the electrode sheet, thus protecting the integrity of the electrode sheet while ensuring the cleaning effect.

[0037] A wiping roller 68 is rotatably connected to the inner surface of the fixed base 64. Both the front and rear ends of the wiping roller 68 are slidably connected to the adjustment groove 641 on the same side. A scraper 69 is fixedly connected to the top side wall of the inner surface of the fixed base 64. A collection box 610 is fixedly connected to the left end of the scraper 69. The outer surface of the wiping roller 68 is in close contact with the scraper 69. A gear 611 is fixedly connected to the front end of the wiping roller 68. A one-way rotating shaft is provided at the connection between the wiping roller 68 and the gear 611. The outer surface of the gear 611 meshes with the rack 63. A handle 612 is fixedly connected to the front end of the gear 611.

[0038] The unidirectional shafts mentioned above can only rotate counterclockwise and cannot rotate clockwise; Furthermore, when the second extrusion plate 62 is at its highest point, the rack 63 and the second gear 611 are separated. At this time, the wiping roller 68 can be lifted as a whole by holding the handle 612 so that the mother roll can pass through in the initial state.

[0039] Furthermore, the raising and lowering of rack 63 will mesh with gear 611 to make it rotate. Only when rack 63 is raised will gear 611 drive its internal one-way rotating shaft to rotate, thereby causing the wiping roller 68 to rotate counterclockwise. When the wiping roller 68 rotates counterclockwise, its surface will scrape over the right end of scraper 69, promptly removing impurities and excess isopropyl alcohol from the surface of the wiping roller 68, ensuring the cleanliness of the surface of the wiping roller 68, ensuring the cleaning quality of the electrode plate, and avoiding secondary contamination of the electrode plate by impurities. The scraped liquid and impurities will be collected in collection box 610.

[0040] It should be noted that the rise of the rack 63 drives the wiping roller 68 to rotate. After the surface of the wiping roller 68 is scraped by the scraper 69, its wetted surface is finally facing downwards, which makes it easier to clean the electrode sheet before the next cutting.

[0041] Therefore, this solution, through the cooperation of the opening and closing component 2, the flattening component 3, the laser cutter 4, the air blowing component 5, and the cleaning component 6, constructs a fully automated closed loop for cleaning, cutting, separating, guiding, flattening, and collecting electrode sheets. Among them, the cooperation of the opening and closing component 2, the flattening component 3, and the air blowing component 5 can smoothly blow the cut electrode sheets into the feed port 261, so that they are smoothly separated from the mother roll and enter between the two smoothing drums 32. During the downward movement of the electrode sheets, the raised edges are flattened simultaneously, ensuring the regularity of subsequent collection. At the same time, the extrusion plate 62 is driven to extrude the water bag 66, so that isopropyl alcohol is intermittently sprayed onto the wiping roller 68, driving the wiping roller 68 to clean the surface of the mother roll in advance, reducing the impact of surface impurities on subsequent cutting and separation, effectively reducing the defect rate caused by defects in a single link, and improving the consistency of the final product.

[0042] It should be noted that the specific installation method, circuit connection method, and control method of the hydraulic device 22 and the laser cutting machine 4 used in this invention are all conventional designs, and will not be described in detail in this invention.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
