Description

Technical Field

[0001] This utility model relates to the field of new energy technology, specifically to an electrode repair device and electrode repair system. Background Technology

[0002] During the die-cutting process of existing electrodes, due to insufficient optical sensing accuracy of the equipment or coating gap errors, a certain proportion of electrode tabs are poorly fed, affecting the electrode tab welding quality and the safety of the finished battery.

[0003] Defective electrode sheets with faulty tabs can be repaired to become good products. Currently, this repair is done manually by hand, wiping the sheets by hand, with employees repairing one sheet at a time. Because the tabs are thin and light, improper handling can easily cause a series of quality problems such as broken or cracked tabs during the repair process; moreover, it is inefficient and wastes labor costs in battery manufacturing.

[0004] In summary, the existing electrode rework process suffers from technical problems such as poor electrode quality, low efficiency, and high labor costs. Utility Model Content

[0005] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose an electrode rework device and electrode rework system to solve the technical problems of poor electrode quality, low efficiency and high labor costs in the prior art.

[0006] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0007] In one aspect, this application provides an electrode rework device, including a panel, a first fixing unit, and a second fixing unit.

[0008] Panel, the panel being used to support the electrode sheet;

[0009] The first fixing unit includes a driving mechanism and a pressure plate. The pressure plate is connected to the driving mechanism in a direction perpendicular to the movement of the panel. The pressure plate has a strip-shaped through hole for fixing the first end of the electrode and exposing the electrode tab.

[0010] The second fixing unit is connected to the panel and is used to position the second end of the electrode.

[0011] In some embodiments of this application, the panel surface is provided with a boss structure, which is disposed opposite to the second fixing unit and is used to position the first end of the electrode sheet.

[0012] In some embodiments of this application, the cross-sectional profile of the strip-shaped through hole is an inverted trapezoid, and the opening area of ​​the strip-shaped through hole facing the panel is smaller than the opening area of ​​the strip-shaped through hole away from the panel.

[0013] In some embodiments of this application, the panel has a transmission hole, the drive mechanism and the pressure plate are respectively disposed on opposite sides of the panel, and the drive mechanism passes through the transmission hole and is connected to the pressure plate for transmission.

[0014] In some embodiments of this application, the drive mechanism includes a cylinder or a motor.

[0015] In some embodiments of this application, a pad is also included, which is disposed on the same side of the panel as the drive mechanism, and the thickness of the pad is greater than the thickness of the drive mechanism.

[0016] In some embodiments of this application, the second fixing unit is provided with a strip-shaped mounting hole, the extension direction of the strip-shaped mounting hole being perpendicular to the extension direction of the strip-shaped through hole.

[0017] In some embodiments of this application, the panel surface is provided with a plurality of threaded holes arranged at intervals in sequence, the arrangement direction of the plurality of threaded holes being parallel to the extension direction of the strip mounting hole, and the second fixing unit being connected to the panel by fasteners passing through the strip mounting hole and part of the threaded holes.

[0037] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose an electrode 5 rework device to solve the technical problems of poor electrode 5 quality, low efficiency and high labor cost in the prior art.

[0038] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0039] like Figures 1-6 As shown. In a first aspect, this application provides an electrode 5 repair device, including a panel 1, a first fixing unit 2, and a second fixing unit 3.

[0040] The panel 1 is used to support the electrode 5; the panel 1 provides a basic working platform for the operation of the electrode 5.

[0041] The first fixing unit 2 includes a drive mechanism 21 and a pressure plate 22. The pressure plate 22 is connected to the drive mechanism 21 in a direction perpendicular to the movement of the panel 1. The pressure plate 22 has a strip-shaped through hole 22a for fixing the first end of the electrode 5 and exposing the tab. The drive mechanism 21 inside the first fixing unit 2 drives the pressure plate 22 to move downward. The pressure plate 22 presses down on the first end of the electrode 5, fixing it in place. The strip-shaped through hole 22a on the pressure plate 22 is precisely aligned with the position of the tab that needs to be repaired, so that the tab is exposed from the hole and fixed in a precise position. The design of the strip-shaped hole also allows the tab to have a certain adjustment range within the hole to accommodate different tab position deviations.

[0042] The second fixing unit 3 is connected to the panel 1 and is used to position the second end of the electrode 5. The second fixing unit 3, connected to the panel 1, positions the second end of the electrode 5. This ensures that the entire electrode 5 is in a stable and correct posture on the panel 1, preventing movement or deformation during subsequent operations. The second fixing unit 3 can be a clamp, a baffle, or other positioning structure.

[0043] After the electrode 5 is securely fixed at both ends and the tabs are precisely exposed, rework operations such as wiping, cleaning, or minor adjustments can be performed on the exposed tabs. Because the electrode 5 and tabs are in fixed positions, this operation can be performed very stably and accurately. The device is designed to support the simultaneous operation of multiple individual electrodes (tabs), significantly improving processing capacity.

[0044] This application utilizes an automated first fixing unit 2 to fix the electrode body and tab positions, allowing simultaneous operation of multiple individual electrodes. This significantly increases the processing speed of the tab cleaning process and solves the problem of low efficiency in existing manual rework. Automated fixing enables more stable and precise tab processing, avoiding quality issues such as broken or cracked tabs that may occur during manual operation. This effectively improves the overall quality of the reworked electrode 5, ensuring the quality of subsequent tab welding and the safety of the finished battery. Consequently, it reduces labor costs in the battery manufacturing process, making the rework process more reliable and controllable.

[0045] In some embodiments of this application, the surface of the panel 1 is provided with a boss structure 1a, which is disposed opposite to the second fixing unit 3 and is used to position the first end of the electrode 5.

[0046] The boss structure 1a on panel 1 guides the placement of electrode 5, initially positioning the first end of electrode 5. Subsequently, the second fixing unit 3 precisely fixes the second end of electrode 5, together ensuring that electrode 5 is stably positioned.

[0047] Improving feeding efficiency, the boss guides the electrode 5 to be placed faster and more accurately. Enhancing positioning stability, the initial limiting reduces electrode 5 movement, facilitating subsequent precise fixing. Improving overall accuracy, the coarse positioning (boss) + fine positioning (second fixing unit 3) work together for more precise positioning. Reducing human error, standardized guidance minimizes operational mistakes.

[0048] In some embodiments of this application, the cross-sectional profile of the strip-shaped through hole 22a is an inverted trapezoid, and the opening area of ​​the strip-shaped through hole 22a facing the panel 1 is smaller than the opening area of ​​the strip-shaped through hole 22a away from the panel 1.

[0049] The opening of the hole is narrower near the bottom of panel 1 and wider away from the top of panel 1. At this time, the position of electrode 5 in the hole is restricted: electrode 5 cannot be easily removed from the hole because the lower opening is narrower, while the upper opening is wider, which facilitates manual or equipment cleaning of the electrode tabs, such as inserting a cotton swab.

[0050] The inverted trapezoidal structure forms an "anti-detachment" mechanism. It is not easy for the electrode to be accidentally displaced or detached due to vibration or external force during subsequent operations, thus ensuring the stability of the electrode 5 position.

[0051] In some embodiments of this application, the panel 1 is provided with a transmission hole, the drive mechanism 21 and the pressure plate 22 are respectively disposed on opposite sides of the panel 1, and the drive mechanism 21 passes through the transmission hole and is connected to the pressure plate 22 in a transmission manner.

[0052] The power generated by the drive mechanism 21 (e.g., cylinder, motor lead screw, etc.) is transmitted to the pressure plate 22 via a connecting member (e.g., connecting rod, push rod, pull rod, screw, etc.) passing through the transmission hole. When the drive mechanism 21 moves, it drives the connecting member passing through the transmission hole to move, thereby driving the pressure plate 22 to move in a direction perpendicular to the panel 1 (usually vertically). Through this transmission method across the panel 1, the drive mechanism 21 can control the pressure plate 22 to press down on the first end of the electrode 5, fix the electrode 5 through the strip-shaped through hole 22a and expose the electrode tab, or loosen the pressure plate 22 as needed.

[0053] Placing the drive mechanism 21 below (or on the back of) the panel 1 makes it easier to place and operate the electrode 5 on the upper surface of the panel 1. Hiding the drive mechanism 21 below the panel 1 may also help to make the overall device more compact.

[0054] In some embodiments of this application, the drive mechanism 21 includes a cylinder or a motor.

[0055] The cylinder uses compressed air to drive the piston in a linear reciprocating motion, which in turn drives the pressure plate 22 to press or release the electrode 5. It has a simple structure, fast response speed, large output force, and relatively low cost.

[0056] The motor rotates, and in conjunction with a transmission mechanism such as a lead screw, rack and pinion, or cam, converts the rotary motion into linear motion of the pressure plate 22, thereby achieving pressing or releasing. The motor offers high control precision, accurate speed and force adjustment, easy automation, and smooth operation.

[0057] In some embodiments of this application, a pad 4 is also included, which is disposed on the same side of the panel 1 as the drive mechanism 21, and the thickness of the pad 4 is greater than the thickness of the drive mechanism 21.

[0058] When the device is working, the drive mechanism 21 is prevented from directly contacting the ground or workbench, thus preventing vibrations and collisions or interference with the ground or workbench during operation and ensuring smooth operation of the mechanism. The pad 4 increases the stability of the overall structure and protects the drive mechanism 21 and the surface of the electrode 5 from damage.

[0059] In some embodiments of this application, the second fixing unit 3 is provided with a strip-shaped mounting hole 3a, the extension direction of the strip-shaped mounting hole 3a being perpendicular to the extension direction of the strip-shaped through hole 22a.

[0060] During installation, the strip mounting hole 3a allows the second fixing unit 3 to be finely adjusted in the vertical direction, working in conjunction with the pressure plate 22 to restrict the movement of the electrode 5 from two vertical directions.

[0061] Precise positioning and dual vertical constraints ensure a more stable fixation of electrode 5. Tolerance adaptability allows for fine-tuning to accommodate variations in electrode 5 dimensions. Easy assembly and adjustment.

[0062] In some embodiments of this application, the surface of the panel 1 is provided with a plurality of threaded holes 1b arranged sequentially at intervals. The arrangement direction of the plurality of threaded holes 1b is parallel to the extension direction of the strip mounting hole 3a. The second fixing unit 3 is connected to the panel 1 by fasteners passing through the strip mounting hole 3a and part of the threaded holes 1b.

[0063] The parallel threaded holes 1b on panel 1 mate with the strip-shaped mounting holes 3a on the second fixing unit 3. By passing a fastener through the strip-shaped hole and screwing it into the selected threaded hole 1b, the position of the second fixing unit 3 can be precisely adjusted in the parallel direction.

[0064] Precise adjustment allows for accurate positioning of the second fixing unit 3, accommodating different electrode sizes 5. High adaptability facilitates adjustment to match different specifications of electrode 5 without requiring component replacement. Improved quality ensures accurate fixing of electrode 5, enhancing rework quality.

[0065] like Figure 7 As shown. In a second aspect, this application also provides an electrode 5 repair system, including an electrode 5 and an electrode 5 repair device as described in any embodiment of the first aspect, wherein the electrode 5 includes an electrode body and an electrode tab connected to each other, the first fixing unit 2 abuts against the first end of the electrode body and the electrode tab in a direction perpendicular to the panel 1 and exposes at least a portion of the electrode tab, and the second fixing unit 3 abuts against the second end of the electrode body in a direction parallel to the panel 1.

[0066] The electrode 5 is placed on the panel 1. The first fixing unit 2 is lifted vertically from below, pressing down one end of the electrode body and exposing the electrode tab. The second fixing unit 3 is pressed horizontally from the side to the other end of the electrode body, so as to achieve stable fixing of both ends of the electrode 5 and the electrode tab.

[0067] Stable and fixed with bidirectional constraints to prevent electrode displacement. Precise positioning and clear exposure of the electrode tabs facilitate subsequent processing. A rational structure combining vertical and horizontal fixation ensures strong adaptability.

[0068] In some embodiments of this application, a plurality of electrode sheets 5 are arranged sequentially at intervals, and the arrangement direction of the electrode sheets 5 is parallel to the extension direction of the strip-shaped through hole 22a.

[0069] Multiple electrode sheets 5 to be repaired are arranged side by side and at equal intervals along the extension direction of the strip-shaped through hole 22a, so that they can pass through the same set of fixed structures simultaneously or sequentially, thus achieving batch processing.

[0070] Improved efficiency: Multiple electrode sheets 5 can be fixed and reworked simultaneously, significantly increasing processing speed. Space-saving: The compact arrangement optimizes equipment layout and floor space. Consistency guaranteed: The orderly arrangement ensures that each electrode sheet 5 is processed in the same position, improving the stability of rework quality.

[0071] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include:

[0072] This application utilizes an automated first fixing unit 2 to fix the electrode body and tab positions, allowing simultaneous operation of multiple individual electrodes. This significantly increases the processing speed of the tab cleaning process and solves the problem of low efficiency in existing manual rework. Automated fixing enables more stable and precise tab processing, avoiding quality issues such as broken or cracked tabs that may occur during manual operation. This effectively improves the overall quality of the reworked electrode 5, ensuring the quality of subsequent tab welding and the safety of the finished battery. Consequently, it reduces labor costs in the battery manufacturing process, making the rework process more reliable and controllable.

[0073] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.
