[0045] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0046] like Figure 2-5 As shown, the present invention provides a device for holding battery electrode sheets, including a mobile trolley 1, a support 2, and a tray 3.

[0047] The support 2 is detachably mounted on the top of the mobile trolley 1. Several angled slots 201 are vertically spaced along its side, and a tray 3 is detachably mounted at each slot 201. The side of the tray 3 is embedded in the angled slot 201 and magnetically connected to it. The top of each tray 3 is used to horizontally place a battery electrode to be tested. In this structure, the detachable design of the support 2 and tray 3 allows multiple electrodes to be placed separately in independent trays 3, avoiding direct compression or stacking between electrodes and reducing wrinkles caused by compression. Magnetic adsorption further secures the connection between the tray 3 and the support 2, preventing the tray 3 from accidentally falling off or shifting during movement or storage, ensuring the stability of the electrode placement, and thus guaranteeing the accuracy of the measurement results.

[0048] In addition, the detachable design of bracket 2 makes it easy to repair the angled slot 201. As the number of insertions increases, the inside of the angled slot 201 is prone to wear. When this problem occurs, bracket 2 can be disassembled and separated from the mobile trolley 1. Then bracket 2 can be moved to the repair station for repair, which is more convenient.

[0049] In addition, a handle is provided at the top of the bracket 2, which makes it easy to move the device.

[0050] like Figure 2 As shown, the mobile cart 1 includes a base 11 and casters 12, wherein the casters 12 are located at the bottom of the base 11; the top of the base 11 is provided with a mounting groove 1101, and the lower end of the bracket 2 is inserted into the mounting groove 1101. In this structure, the mobile cart 1 achieves flexible mobility of the device through the combination of the base 11 and the casters 12, facilitating the transportation of the electrode sheets in different experimental stages; the mounting groove 1101 of the base 11 provides a standardized installation interface for the bracket 2, ensuring a stable connection between the bracket 2 and the mobile cart 1, and preventing the bracket 2 from shaking due to movement, which would affect the fixing effect of the tray 3.

[0051] like Figure 2 As shown, the mounting slot 1101 is a T-shaped slot, and the lower end of the bracket 2 has a T-shaped structure. The front and rear ends of the T-shaped slot are open, and the T-shaped slot and the T-shaped structure are interlocked. This allows for quick and accurate installation of the bracket 2 and the base 11, and assembly can be completed without additional tools, improving operational efficiency.

[0052] In addition, the T-shaped groove structure facilitates the installation of the bracket 2, enhances the stability of the connection between the bracket 2 and the mobile trolley 1, reduces the tilting or loosening of the bracket 2 due to uneven force, and further ensures the horizontal placement of the tray 3.

[0053] In addition, the mobile trolley 1 also includes a hand-tightening screw 13, which is screwed into the bottom of the base 11. One end of the hand-tightening screw 13 extends into the T-shaped groove and abuts against the bottom of the T-shaped structure. Specifically, the bottom of the base 11 has an opening that runs vertically through the base 11, and the inner wall of the opening is threaded. The screw of the hand-tightening screw 13 is screwed into this opening. When it is necessary to fix the bracket 2, the hand-tightening screw 13 is tightened so that the upper end of the screw presses upward against the bottom of the T-shaped structure at the lower end of the bracket 2, thereby fixing the bracket 2. By tightening the hand-tightening screw 13, the bracket 2 can be prevented from loosening due to long-term use or external impact, improving the overall reliability of the device and avoiding the displacement of the tray 3 or the tilting of the electrode due to the loosening of the bracket 2.

[0054] like Figure 3 As shown, the bracket 2 has angled slots 201 on both its left and right sides. The opening of the angled slot 201 is located diagonally above the bottom of the slot and tilts outward from the bracket 2. The side of the tray 3 near the bracket 2 is bent downward to form a plug-in part 301. The plug-in part 301 is inserted into the angled slot 201. In this structure, the angled design of the angled slot 201 allows the plug-in part 301 of the tray 3 to be quickly inserted at an angle, facilitating the installation of the tray 3. At the same time, the self-locking effect between the tray 3 and the bracket 2 is enhanced by gravity and the tilt angle, reducing the risk of the tray 3 sliding during storage or transportation. Moreover, this plug-in design allows for adjustment of the spacing between the upper and lower trays 3, adapting to the placement requirements of electrode sheets of different thicknesses and improving compatibility.

[0055] In addition, the symmetrically arranged oblique slots 201 on both sides improve the overall stability of the device. At the same time, they also expand the distribution range of the trays 3, allowing the device to transfer more electrode sheets and improve the efficiency of the peel force test.

[0056] In addition, the front and rear ends of the angled slot 201 are open. This ensures that the front and rear ends of the angled slot 201 do not interfere with the insertion of the plug part 301, making the installation of the tray 3 smooth.

[0057] like Figure 3 As shown, a magnet 21 is fixed on the bottom of the inclined slot 201, and a corresponding iron plate 31 is fixed on the bottom of the insertion part 301. The magnet 21 and the iron plate 31 are magnetically connected to achieve the magnetic connection between the tray 3 and the inclined slot 201.

[0058] like Figure 5 As shown, the top of the tray 3 is provided with a placement groove 302 for horizontally placing the electrode sheets. The bottom surface of the placement groove 302 is smooth and flat, without any sharp protrusions, avoiding the risk of scratching the electrode sheets. At the same time, numbers can be marked on the bottom of the groove with an erasable pen, making it easy for the experimenter to quickly identify the placement position when storing and retrieving the electrode sheets.

[0059] Furthermore, the end of the placement groove 302 furthest from the support 2 extends horizontally outward through the side of the tray 3 to form an opening 303, while the other end (the end of the placement groove 302 closest to the support 2) has an arc-shaped corner protection groove 304. In this structure, the opening 303 facilitates the insertion and removal of the electrode sheet. The corner protection groove 304 prevents interference with the electrode sheet at the corner of the placement groove 302, reducing the formation of wrinkles.

[0060] like Figure 5 As shown, a rubber stopper 22 is provided on the tray 3. Specifically, a mounting hole 305 is provided on the inner side of the opening 303, and the mounting hole 305 extends vertically through the bottom of the placement groove 302. The rubber stopper 22 is located inside the mounting hole 305, and its side surface elastically abuts against the hole wall of the mounting hole 305. The elastic abutment refers to the contact pressure generated by the elastic deformation of the rubber stopper 22. The rubber stopper 22 can limit the electrode sheet, preventing it from slipping out of the placement groove 302 during transportation, thus protecting the electrode sheet. At the same time, the flexibility of the rubber avoids surface damage caused by hard contact, further improving the safety and integrity of the stored electrode sheet.

[0061] In addition, the rubber stop 22 has flanges 221 at both its upper and lower ends, and a countersunk hole 306 is provided at the upper end of the mounting hole 305. The upper flange 221 can selectively enter or exit the countersunk hole 306, while the lower flange 221 is located below the tray 3. The thickness of the flange 221 is less than the depth of the countersunk hole 306. When the rubber stop 22 is pressed upward, the upper end of the rubber stop 22 can protrude into the placement groove 302 to limit the electrode and prevent horizontal displacement of the electrode. When the rubber stop 22 is pressed downward, the flange 221 at the upper end of the rubber stop 22 can be pressed into the countersunk hole 306, making the bottom of the placement groove 302 at the opening 303 flat, which facilitates the placement and removal of the electrode.

[0062] It should be noted that the diameter of the rubber stop 22 is slightly larger than the diameter of the mounting hole 305 (e.g., the diameter of the rubber stop 22 is 0.5-1mm larger than the mounting hole 305). The tight fit is achieved through elastic deformation. When the rubber stop 22 is subjected to pressure, it can move up and down in the mounting hole 305. When the pressure is released, the elastic force can maintain the position of the rubber stop 22 after displacement.

[0063] In addition, the design of the two flanges 221 is to prevent the rubber stop 22 from sliding out of the mounting hole 305 due to excessive pressure.

[0064] The method of using the device for holding battery electrode sheets according to this utility model is as follows:

[0065] When testing the peel force, the sampled battery electrode sheets are laid flat on the tray 3. Then, the insertion part 301 of the tray 3 is inserted into the angled slot 201, and the rubber stop 22 is pressed upward so that the upper flange 221 enters the placement groove 302, completing the installation of one tray 3. After installing multiple trays 3 in this way, they are transported. Upon arrival at the destination, the rubber stop 22 is pressed downward so that the lower flange 221 falls into the countersunk hole 306, at which point the electrode sheet can be removed through the opening 303.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
