Description

Technical Field

[0001] This utility model pertains to electrode preparation equipment, specifically, it relates to a modular high-precision electrode coating device. Background Technology

[0002] Electrode devices are components in electronic or electrical devices and equipment. Due to their diverse applications, functional coatings are often added to their surfaces. Electrode coating equipment is indispensable in the electrode fabrication process, and its performance directly affects battery quality and safety. Currently, most electrode coating devices adopt an integrated structure, which has the following drawbacks: 1. The high degree of integration between the slurry supply system and coating mechanism in existing electrode coating devices leads to difficulties in cleaning and maintenance, increasing equipment maintenance costs and downtime; 2. The pressure adjustment of the coating rollers in existing electrode coating devices relies on manual operation, easily causing uneven coating thickness, affecting coating quality, and is cumbersome to operate; 3. The multi-axis motion system of existing electrode coating devices uses a rigid connection method, making it difficult to adapt to the processing requirements of electrode substrates of different sizes, and lacking flexibility during processing; 4. The complex structure of existing electrode coating devices and poor coordination between various components result in low coating accuracy and difficulty in achieving high-precision coating trajectory control.

[0003] Several invention patents have been issued to address the challenges of modular assembly / disassembly, multi-axis precision control, and high coating uniformity. For example, CN215612739U discloses a high-precision gap coating device, including a coating roller frame, a coating roller, a coating head frame, a coating head, and a cylinder-driven device. This device, through the cooperation of the cylinder-driven device and the servo-driven device, can precisely control the running speed and reciprocating accuracy of the coating head frame, ensuring that the coating head frame returns to its initial position after the joint passes, maintaining a constant coating gap. However, this device still suffers from insufficient control precision in terms of the moving speed and reciprocating accuracy of the coating head frame. CN111530694A discloses a battery electrode coating device, including a frame, a slurry removal mechanism, a slurry scraping mechanism, a slurry tank, and a positioning roller. This device automatically coats and evens out the electrode sheets, and removes residual slurry from the slurry-free areas on both sides of the electrode sheet, resulting in uniform overall coating, high coating efficiency, and good coated electrode quality. However, this device still needs further improvement in terms of the uniformity and efficiency of electrode coating.

[0004] It is evident that the production efficiency and coating quality of current electrode coating devices cannot meet the ever-increasing demands for high-precision and high-efficiency production. There is an urgent need for a high-precision modular electrode coating device that can be quickly assembled and disassembled, with precisely controllable coating paths, to address the many shortcomings of existing technologies.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0035] In the following embodiments, the instruments, drugs, and materials used can be commercially obtained without special instructions.

[0036] As Figure 1 shown, this embodiment provides a modular high-precision electrode coating device, mainly including a program control module 1, a feeding module 2, and an electrode coating module 3.

[0037] The program control module 1 is signal-connected to the Y1-axis motor 301, Y2-axis motor 303, X-axis motor 305, and Z-axis motor 307 of the electrode coating module 3. The program control module 1 controls the linkage of the Y1-axis motor 301, Y2-axis motor 303, X-axis motor 305, and Z-axis motor 307 by presetting coordinate parameters. The program control module 1 has multiple groups of preset coating programs, including linear coating, wavy coating and other modes, and users can select or customize the motion trajectory parameters through the touch screen interface.

[0038] The feeding module 2 includes a stirring motor 201, a stirring paddle 202, a slurry storage device 203, and a feeding peristaltic pump 204. The stirring motor 201 is connected to the stirring paddle 202, and the slurry in the slurry storage device 203 is stirred by the stirring paddle 202 to prevent the slurry from settling. The stirring speed of the stirring motor 201 can be adjusted by a knob. The feeding peristaltic pump 204 is connected to the bottom of the slurry storage device 203 through a pipeline and can accurately adjust the feeding speed. The feeding peristaltic pump 204 realizes pulse-free quantitative delivery, and the slurry stored in the slurry storage device 203 is pumped to above the coating roller 3093 of the electrode coating module 3 through a pipeline and drips vertically.

[0039] The electrode coating module 3 includes a multi-axis drive system, a rolling coating device 309, an electrode substrate fixing device 310, and a fixed plate 311.

[0040] The fixing plate 311 is typically placed horizontally on the platform and is used to connect and fix other components in the electrode coating module 3 with bolts, facilitating individual maintenance or replacement. The electrode substrate fixing device 310 is fixed to the surface of the fixing plate 311 by bolts and is used to clamp the electrode substrate to be coated. The installation position of the electrode substrate fixing device 310 can be adjusted to meet the processing requirements of electrodes of different sizes.

[0041] As a preferred embodiment, the fixing plate 311 is provided with standardized positioning pin holes, which facilitates individual maintenance or replacement, reduces equipment maintenance time, and improves equipment service life.

[0042] The multi-axis drive system includes a Y1-axis motor 301, a Y1-axis sliding lead screw 302, a Y2-axis motor 303, a Y2-axis sliding lead screw 304, an X-axis motor 305, an X-axis sliding lead screw 306, a Z-axis motor 307, and a Z-axis sliding lead screw 308.

[0043] The Y1-axis sliding screw 302, Y2-axis sliding screw 304, X-axis sliding screw 306, and Z-axis sliding screw 308 are respectively connected to the Y1-axis motor 301, Y2-axis motor 303, X-axis motor 305, and Z-axis motor 307, and each is equipped with a sliding platform. Driven by the Y1-axis motor 301, Y2-axis motor 303, X-axis motor 305, and Z-axis motor 307, the linear motion of each sliding platform is achieved through the Y1-axis sliding screw 302, Y2-axis sliding screw 304, X-axis sliding screw 306, and Z-axis sliding screw 308.

[0044] The Y1-axis sliding lead screw 302 and Y2-axis sliding lead screw 304 are arranged in parallel and fixed to the surface of the fixed plate 311. The X-axis sliding lead screw 306 is mounted on the Y1-axis sliding lead screw 302 and Y2-axis sliding lead screw 304, and is perpendicular to both Y1-axis and Y2-axis sliding lead screws 304. Both ends of the X-axis sliding lead screw 306 are fixedly connected to the sliding platforms on which the Y1-axis and Y2-axis sliding lead screws 302 and 304 are mounted. The Z-axis sliding lead screw 308 is mounted on the front end of the X-axis sliding lead screw 306 and is perpendicular to the X-axis sliding lead screw 306. The Z-axis sliding lead screw 308 is fixedly connected to the sliding platform on which the X-axis sliding lead screw 306 is mounted. Thus, the multi-axis drive system forms a four-axis linkage three-dimensional precision motion mechanism.

[0045] Photoelectric sensors are respectively installed at the ends of the Y1-axis sliding lead screw 302, Y2-axis sliding lead screw 304, X-axis sliding lead screw 306 and Z-axis sliding lead screw 308 to detect overtravel and trigger emergency stop protection. This not only ensures the accuracy of the coating position each time, but also avoids collisions between the moving parts.

[0046] The rolling coating apparatus 309 includes a coating mounting frame 3901, a coating support frame 3092, and coating rollers 3093. The coating mounting frame 3901 is integrally formed by a back plate and side plates, with the two side plates located on either side of the back plate and perpendicular to it. The back plate of the coating mounting frame 3901 is fixedly connected to a sliding platform mounted on a Z-axis sliding screw 308 via screws. The coating support frame 3092 is integrally formed by a crossbeam and a longitudinal beam, with the two longitudinal beams located at both ends of the crossbeam and the crossbeam located in the middle of the longitudinal beam. The upper part of the longitudinal beam of the coating support frame 3092 is fixedly connected to the side plates of the coating mounting frame 3901 via screws, and the lower part of the longitudinal beam of the coating support frame 3092 is connected to the coating rollers 3093. The coating rollers 3093 can be made in different lengths according to the required coating area, or one or more roller types can be used depending on the state of the coating slurry. The surface material of the rollers can also be selected according to the solvent of the coating slurry, including stainless steel, plexiglass, and rubber-coated rollers. When the coating roller 3093 contacts the fixed electrode substrate below, one or more rollers roll simultaneously as driven by the four-axis motor, uniformly coating the slurry onto the surface of the electrode substrate.

[0047] The program control module 1 is connected to the Y1 axis motor 301, Y2 axis motor 303, X axis motor 305, and Z axis motor 307 via cables. It integrates a motion control card and a PLC controller, and supports the following functions:

[0048] (1) Coordinate parameterization control: The user inputs the starting and ending coordinates of the coating area and the coating speed, and the program automatically generates a four-axis linkage path;

[0049] (2) Program editing and storage: The built-in touch screen interface allows users to freely edit the coating trajectory and save it to the program library.

[0050] In addition, the program control module 1 has a built-in overload current monitoring circuit that automatically cuts off the power supply when the current of the stirring motor 201, Y1 axis motor 301, Y2 axis motor 303, X axis motor 305, and Z axis motor 307 is abnormal.

[0051] The program control module 1 is connected to the Y1-axis motor 301, Y2-axis motor 303, X-axis motor 305, and Z-axis motor 307 via cables. It drives the Y1-axis sliding screw 302, Y2-axis sliding screw 304, X-axis sliding screw 306, and Z-axis sliding screw 308 to control the linear movement of the sliding platforms on which it is installed, thus completing the coating program. The Y1-axis and Y2-axis sliding screws 302 and 304 control the lateral position of the rolling coating device 309, while the X-axis sliding screw 306 controls the longitudinal movement of the rolling coating device 309, forming a planar coating path. The Z-axis sliding screw 308 enables vertical fine-tuning of the coating device 309 (accuracy up to ±0.1mm).

[0052] The coating device has standardized interfaces between the program control module 1, the feeding module 2, and the electrode coating module 3, including quick-release electrical / fluid interfaces between the modules.

[0053] The following example illustrates the usage process of the modular high-precision electrode coating device in this embodiment, using a specific working condition as an example. The specific operation is as follows:

[0057] Weigh the activated carbon, binder, and solvent according to a mass ratio of 1:0.5:10, mix them together, and pour them into the slurry storage device 203. Start the stirring motor 201 and stir at a speed of 400 rpm. Stir continuously during the coating process.

[0058] 3. Coating Program Editing

[0059] Open the program control module, edit the coating program via the touch screen, save the edited program, and name it T1.

[0060] 4. Electrode coating

[0061] A stainless steel coating roller 3093 with a length of 5cm and a diameter of 10mm is mounted on a coating support frame 3092.

[0062] Turn on the peristaltic pump 204 and set the extraction speed to 8 mL / min. The slurry is drawn from the bottom of the slurry storage device 203 and pumped to the top of the coating roller by the peristaltic pump 204, where it drips vertically.

[0063] When coating program T1 is started, the Y1-axis motor 301, Y2-axis motor 303, X-axis motor 305, and Z-axis motor 307 drive the Y1-axis sliding screw 302, Y2-axis sliding screw 304, X-axis sliding screw 306, and Z-axis sliding screw 308 to rotate, respectively. The rolling coating device 309 runs along the path set in the program. The two rollers roll simultaneously, uniformly coating the slurry onto the surface of the carbon felt electrode substrate.
