Technical Field

[0001] This utility model relates to the field of battery processing technology, specifically to an integrated device for rapid coating and roll forming of battery electrodes. Background Technology

[0002] With the rapid development of the new energy industry, the demand for lithium-ion batteries has increased dramatically. As a core component of batteries, the efficiency and precision of the manufacturing process of battery electrodes directly affect battery performance. In traditional battery electrode production processes, coating and rolling are usually two separate steps: first, a slurry is coated onto a metal foil substrate using a coating machine, and then it is transferred to a rolling mill for compaction. This step-by-step processing method has the following problems: Changing processes requires repositioning and fixing the workpiece, which increases production time, and multiple handling may cause damage or contamination to the electrode sheets; positioning errors between independent equipment can easily lead to misalignment of the coating and rolling areas, affecting the uniformity of electrode sheet thickness. Utility Model Content

Therefore, one objective of this utility model is to provide an integrated device for rapid coating and roll forming of battery electrode sheets, comprising: Workbench; A displacement mechanism is provided on the worktable and is movable along the length of the worktable; A placement component is provided on the displacement mechanism, and the placement component can place a workpiece. The two ends of the placement component can move closer or further apart to be suitable for clamping the workpiece. A coating roller pressing mechanism is provided on the worktable and spaced apart from the upper end of the placement assembly. The coating roller pressing mechanism can be elastically raised or lowered in the vertical direction to be suitable for coating or rolling the workpiece on the placement assembly.

[0004] Preferably, the displacement mechanism includes: Two fixing plates are disposed on the worktable and arranged along the length of the worktable, with the two fixing plates spaced apart. Two slide rails are respectively disposed on the top of the two fixed plates and are respectively arranged along the length direction of the two fixed plates; A lead screw module is disposed on the worktable and arranged along the length of the worktable, and the lead screw module is disposed between the two fixed plates; A sliding plate is slidably mounted on two slide rails, and the middle part of the sliding plate is connected to the transmission end of the lead screw module.

[0010] The above-described solution of this utility model has at least the following beneficial effects: The battery electrode sheet to be processed (such as a metal foil substrate) is laid flat on the placement assembly. The workpiece is clamped at both ends of the placement assembly to accommodate the fixing requirements of electrode sheets of different sizes. The displacement mechanism drives the placement assembly and the workpiece to be precisely positioned below the coating roller pressing mechanism. The coating roller pressing mechanism descends vertically, so that the coating assembly contacts the workpiece surface. Under the continuous movement of the displacement mechanism, the coating assembly evenly coats the workpiece surface with slurry. At the same time, the elastic pressure of the coating roller pressing mechanism avoids excessive coating pressure that could cause slurry splashing or substrate deformation. After coating, the roller pressing assembly (such as a pressure roller) contacts the coating layer surface and presses the coating layer to ensure that the coating layer is compacted, ensuring uniform thickness and coating density. After roller pressing, the displacement mechanism moves the placement assembly away from the coating roller pressing mechanism, and the worker removes the workpiece from the placement assembly. The coating and rolling functions are integrated into the same station. The workpiece is continuously coated and rolled through a displacement mechanism, eliminating intermediate handling and positioning steps and significantly shortening the production cycle. The coating and rolling mechanism is driven by a cylinder combined with a buffer component (such as a compression spring) to provide flexible buffering when pressure is applied, avoiding rigid impact damage to the electrode sheet, while ensuring uniform pressure distribution and improving coating density and thickness consistency. The sliding rod and tension spring design of the placement component can automatically clamp electrode workpieces of different sizes without manual adjustment, simplifying the operation process and adapting to diverse production needs.

[0021] The following describes in detail, with reference to the accompanying drawings, an integrated device for rapid coating and roll forming of battery electrodes according to an embodiment of the present invention.

[0022] Please see Figures 1-5 In this embodiment, the following components are included: a worktable 1; a displacement mechanism 2, which is disposed on the worktable 1 and is movable along the length of the worktable 1; a placement assembly 3, which is disposed on the displacement mechanism 2 and can place workpieces, and the two ends of the placement assembly 3 can move closer or further apart to clamp the workpieces; and a coating roller pressing mechanism 4, which is disposed on the worktable 1 and spaced apart at the upper ends of the placement assemblies 3, and can elastically rise or fall in the vertical direction to coat or roll the workpieces on the placement assemblies 3. The battery electrode sheet to be processed (such as a metal foil substrate) is laid flat on the placement component 3. The workpiece is clamped at both ends of the placement component 3 to accommodate the fixing requirements of electrode sheets of different sizes. The displacement mechanism 2 drives the placement component 3 and the workpiece to be precisely positioned below the coating roller pressing mechanism 4. The coating roller pressing mechanism 4 descends vertically, so that the coating component 407 contacts the workpiece surface. Under the continuous movement of the displacement mechanism 2, the coating component 407 evenly coats the slurry onto the workpiece surface. At the same time, the elastic pressure of the coating roller pressing mechanism 4 avoids excessive coating pressure that could cause slurry splashing or substrate deformation. After coating, the roller pressing component 408 (such as a pressure roller) contacts the coating layer surface and presses the coating layer to ensure uniform thickness and coating density. After roller pressing, the displacement mechanism 2 moves the placement component 3 away from the coating roller pressing mechanism 4, and the worker removes the workpiece from the placement component 3. The coating and rolling functions are integrated into the same station. The workpiece is continuously coated and rolled by the displacement mechanism 2, eliminating intermediate handling and positioning steps and greatly shortening the production cycle. The coating and rolling mechanism 4 is driven by the cylinder 404 and combined with the buffer component 405 (such as the compression spring 4055) to provide flexible buffering when pressure is applied, avoiding rigid impact damage to the electrode sheet, while ensuring uniform pressure distribution and improving the density and thickness consistency of the coating. The slide bar 303 and tension spring 305 of the placement component 3 are designed to automatically clamp electrode workpieces of different sizes without manual adjustment, simplifying the operation process and adapting to diverse production needs.

[0023] In this embodiment, the displacement mechanism 2 includes: two fixed plates 201, which are disposed on the worktable 1 and arranged along the length of the worktable 1, and are spaced apart; two slide rails 202, which are respectively disposed on the top of the two fixed plates 201 and are respectively arranged along the length of the two fixed plates 201; a lead screw module 203, which is disposed on the worktable 1 and arranged along the length of the worktable 1, and is disposed between the two fixed plates 201; a slide plate 204, which is slidably disposed on the two slide rails 202, and the middle part of the slide plate 204 is connected to the transmission end of the lead screw module 203; and a placement component 3 is disposed on the slide plate 204. When the placement component 3 places a workpiece, the lead screw module 203 can rotate to move the slide plate 204 on the two slide rails 202, thereby moving the placement component 3 to below the coating roller pressing mechanism 4.

[0024] In this embodiment, the storage assembly 3 includes: a storage plate 301 disposed on a sliding plate 204; two sliding grooves 302 respectively disposed on both sides of the storage plate 301 and passing through both sides of the storage plate 301; two sliding rods 303 respectively slidably disposed within the two sliding grooves 302; two clamping plates 304 respectively disposed at the ends of the two sliding rods 303; and a tension spring 305 disposed within the sliding groove 302. One end of 305 is connected to the sliding groove 302, and the other end is connected to the slide rod 303. Before placing the workpiece, the operator can pull one side of the clamping plate 304 to stretch the tension spring 305. Then, the operator places the uncoated workpiece on the placement plate 301 and releases the pulled clamping plate 304 so that the stretched tension spring 305 drives the clamping plate 304 to move towards the workpiece. This allows the clamping plates 304 on both sides to clamp the workpiece together, ensuring that the workpiece will not be displaced during coating or rolling.

[0025] In this embodiment, the coating roller pressing mechanism 4 includes: a fixed frame 401, which is mounted on the worktable 1; two sliding columns 402, which are vertically slidably mounted on the fixed frame 401 and spaced apart; a connecting plate 403, which is located at the bottom of the two sliding columns 402; a cylinder 404, which is vertically mounted on the fixed frame 401 and whose transmission end passes through the fixed frame 401 and connects to the connecting plate 403; multiple buffer components 405, which are equally spaced at the bottom of the connecting plate 403; and a mounting plate 406. Mounting plate 406 is located at the bottom of multiple buffer components 405; coating component 407 is located at one end of the bottom of mounting plate 406; rolling component 408 is located at the other end of the bottom of mounting plate 406; when the placement component 3 moves to below the coating component 407 or the rolling component 408, the cylinder 404 descends vertically so that the coating component 407 and the rolling component 408 can press against the surface of the workpiece. First, the workpiece is coated by the coating component 407, and then rolled by the rolling component 408. After the rolling is completed, the workpiece is removed by the operator.

[0026] In this embodiment, the buffer assembly 405 includes: a fixed cylinder 4051, which is vertically disposed at the bottom of the mounting plate 406; a limiting plate 4052, which is disposed at the bottom of the fixed cylinder 4051 and has a through hole in the middle, which is coaxially disposed with the fixed cylinder 4051 and has a diameter smaller than that of the fixed cylinder 4051; a movable plate 4053, which is slidably disposed within the fixed cylinder 4051; and a fixed post 4054, which is vertically disposed within the fixed cylinder 4051 and has a diameter smaller than that of the fixed cylinder 4051. The bottom of the component passes through a through hole and is connected to the mounting plate 406; a compression spring 4055 is vertically installed inside the fixed cylinder 4051, one end of the compression spring 4055 is connected to the fixed cylinder 4051, and the other end is connected to the moving plate 4053; when the coating component 407 or the rolling component 408 contacts the surface of the workpiece, the fixed column 4054 will push the moving plate 4053 to compress the compression spring 4055, which can dynamically adjust the pressure applied to the workpiece during coating or rolling, thereby ensuring that the pressure on the workpiece is consistent during coating or rolling.

[0027] In this embodiment, two limiting blocks 409 are provided at the top of the two sliding columns 402 respectively. The two limiting blocks 409 can limit the maximum distance of the two sliding columns 402 to descend, ensuring that the coating assembly 407 or the rolling assembly 408 will not shift due to the sliding column 402 detaching from the fixing frame 401.
