Description

Technical Field

[0001] This invention relates to the field of power battery manufacturing technology for new energy vehicles, and in particular to an integrated device for stacking, aligning and transferring copper foil electrode sheets for new energy vehicles. Background Technology

[0002] In the production process of power batteries for new energy vehicles, copper foil electrodes are core conductive components. The accuracy of their stacking, alignment and transfer directly affects the electrochemical performance and safety stability of the battery. Currently, the industry uses single-function mechanical devices to process copper foil electrodes. This involves stacking the electrodes layer by layer manually or with simple clamps, then aligning and adjusting them with a positioning mechanism, and finally transferring them to the next process using transfer equipment.

[0003] However, copper foil electrodes are thin and smooth, and adjacent electrodes are prone to sticking together due to electrostatic adsorption or air pressure during stacking. This can cause deformation and wrinkling of the electrodes when they are picked up or transferred, affecting the accuracy of subsequent processing. Furthermore, stacking and alignment are carried out in steps without a real-time synchronous separation and positioning structure, which can easily lead to problems such as edge misalignment and interlayer displacement of the electrodes, thereby reducing the consistency of battery assembly. Existing devices do not have specific buffer protection and adaptive separation mechanisms. The electrodes are easily subjected to mechanical impact during stacking and transfer, resulting in edge damage or surface scratches, which can affect the cycle life and safety performance of the battery. Summary of the Invention

[0004] The present invention solves the problems mentioned in the background art by avoiding deformation of the copper foil during handling and automatically separating the copper foil to avoid collisions between the copper foil during the transfer process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated device for stacking, aligning and transplanting copper foil electrode sheets for new energy vehicles, including a holding rack, a buffer pad fixedly connected to the inner wall of the holding rack, a groove opened on the surface of the buffer pad, a separating mechanism provided inside the groove, a connecting mechanism provided on the side of the buffer pad near the separating mechanism, and an air pipe fixedly connected to the outer surface of the holding rack. The connecting mechanism can engage with the separating mechanism, and the two engage to form an air passage. The air pipe is connected to the connecting mechanism. When copper foil is placed inside the holding rack, the separating mechanism can rotate. The air delivered by the air pipe enters the separating mechanism through the connecting mechanism and is blown into the gap between two adjacent copper foil sheets through the separating mechanism, so that an air gap is formed between each layer of copper foil sheets.

[0006] Preferably, the separating mechanism includes a rotating shaft with an air duct inside. External gears are fixedly connected to both ends of the rotating shaft surface. A partition is fixedly connected to the middle of the rotating shaft surface. A nozzle is fixedly connected inside the partition. A sponge pad is fixedly connected to the side wall of the partition. A pressure switch is fixedly connected to the middle of the sponge pad on the side wall of the partition. A transmission gear meshes with the side of the external gear. A torsion spring is provided inside the transmission gear. A transmission plate meshes with the side of the transmission gear away from the external gear. A push-out spring is fixedly connected to the bottom of the transmission plate. An electromagnetic block is fixedly connected to the side of the buffer pad near the push-out spring.

[0007] Preferably, the connecting mechanism includes a main air duct, a branch air duct fixedly connected to the side of the main air duct, a mounting bracket fixedly connected to the bottom of the branch air duct, a connecting pipe fixedly connected to the bottom of the mounting bracket, a support frame fixedly connected to the end of the connecting pipe away from the mounting bracket, a connector fixedly connected to the bottom of the support frame, a tapered groove formed inside the connector, an air hole formed at the bottom of the mounting bracket, a support rod fixedly connected to the center of the bottom of the mounting bracket, a sealing block fixedly connected to the end of the support rod away from the mounting bracket, a limit rod fixedly connected to the upper surface of the support frame, a compression spring wound around the surface of the limit rod, a buffer pad rotatably connected to a horizontal pipe located on the lower side of the support frame, and a flange fixedly connected to the end of the horizontal pipe.

[0008] Preferably, the holding rack is a square frame composed of four L-shaped plates, the buffer pad is a rubber block, and there are four sets of separating mechanisms, which are located inside the buffer pads on the surfaces of the four L-shaped plates, with each set of separating mechanisms having one separator, and the separators are evenly distributed on the surface of the buffer pads.

[0009] Preferably, a horizontal plate is fixedly connected to the bottom of the transmission plate inside the lowest end of the buffer pad separating mechanism, and a return spring is fixedly connected to the bottom of the horizontal plate.

[0010] Preferably, the rotating shaft is rotatably connected inside the groove, the buffer pad has a movable groove on the side of the groove, the transmission plate is slidably connected inside the movable groove, and the ejector spring is fixedly connected to the bottom of the movable groove.

[0011] Preferably, a power source is fixedly connected inside the buffer pad, one end of the pressure switch is connected to the power source via a wire, and the other end of the pressure switch is connected to the electromagnetic block via a wire.

[0012] Preferably, the upper half of the surface of the transmission plate near the transmission gear has gear teeth, and the lower half is a smooth plane.

[0013] Preferably, the main air duct is connected to the air pipe, the main air duct is connected to the branch air duct, and the branch air duct is connected to the conical groove through a connecting pipe.

[0014] Preferably, the end of the flange away from the horizontal tube is fixedly connected to the axis of the rotating shaft, the surface of the horizontal tube is provided with a circular groove, and the connector is a conical block.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, the problem of copper foil electrode stacking adhesion and deformation is effectively solved by the coordinated design of layer separation and air gap. The separation mechanism can automatically unfold layer by layer as the electrode is put in, and form a gap with the air transported by the air passage, completely avoiding electrostatic adsorption and air pressure adhesion between adjacent electrodes, ensuring that the electrode remains flat during stacking, picking and transplanting, and avoiding bending and damage.

[0016] 2. In this invention, the use of buffer pads and sponge pads can effectively alleviate the impact force when the electrode is placed, avoiding edge damage. The linkage control of the pressure switch and the electromagnetic block allows the separation mechanism to be automatically triggered and deployed only when the electrode is placed. The air path is synchronously opened to form an air gap. The on-demand working mode not only ensures the protective effect, but also achieves the effect of adaptive buffering and precise control, improving the integrity of electrode processing.

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figure 1As shown, an integrated device for stacking, aligning, and transplanting copper foil electrode sheets for new energy vehicles includes a holding rack 2. A support 1 is fixedly connected to the outer side of the holding rack 2. A stepper motor 3 is fixedly connected to the support 1 near the bottom of the holding rack 2. A push plate 4 is rotatably connected to the output end of the stepper motor 3. The stepper motor 3 drives the push plate 4 to move through the support rod. When the copper foil is placed inside the holding rack 2, the stepper motor 3 drives the push plate 4 to descend sequentially. When it is necessary to remove the copper foil, the stepper motor 3 drives the push plate 4 to rise sequentially, which facilitates the removal of the copper foil.

[0022] like Figure 2 and Figure 3 As shown, a buffer pad 5 is fixedly connected to the inner wall of the holding rack 2. The surface of the buffer pad 5 has a groove 6, and the interior of the groove 6 has a separating mechanism 7. The holding rack 2 is a square frame composed of four L-shaped plates. The buffer pad 5 is a rubber block. There are four sets of separating mechanisms 7, which are located inside the buffer pad 5 on the surface of the four L-shaped plates. Each set of separating mechanisms 7 has 25 separates. The 25 separating mechanisms 7 are evenly distributed on the surface of the buffer pad 5, so that multiple copper foils can be placed inside the holding rack 2. Multiple copper foils can be stacked inside the holding rack 2, and each copper foil can be separated by the separating mechanism 7.

[0023] like Figure 4 and Figure 5 As shown, the dividing mechanism 7 includes a rotating shaft 701, which is rotatably connected to the inside of the groove 6 and is capable of rotating inside the groove 6. like Figure 5 As shown, external gears 703 are fixedly connected to both ends of the surface of the rotating shaft 701, and transmission gears 708 mesh with the sides of the external gears 703, as shown. Figure 8 As shown, a torsion spring 709 is provided inside the transmission gear 708. A transmission plate 710 meshes with the side of the transmission gear 708 away from the external gear 703. The upper half of the surface of the transmission plate 710 near the transmission gear 708 is provided with gear teeth, and the lower half is a smooth plane. When the transmission plate 710 moves downward, it drives the transmission gear 708 to rotate through the gear teeth on the side. The transmission gear 708 drives the external gear 703 to rotate. At this time, the partition 704 rotates with the rotating shaft 701. The partition 704 unfolds from the inside of the groove 6 to separate the copper foil placed inside the holding rack 2. like Figures 6-8As shown, the buffer pad 5 has a movable groove on the side of the groove 6. The transmission plate 710 is slidably connected inside the movable groove, and the ejector spring 711 is fixedly connected to the bottom of the movable groove. The bottom of the transmission plate 710 is fixedly connected to the ejector spring 711. The bottom of the transmission plate 710 inside the bottommost partition mechanism 7 of the buffer pad 5 is fixedly connected to the horizontal plate 713. The bottom of the horizontal plate 713 is fixedly connected to the return spring 714. When the first copper foil is placed inside the container 2, the bottom horizontal plate 713 is pressed. At this time, the horizontal plate 713 moves downward against the elastic force of the return spring 714. At this time, the horizontal plate 713 drives the transmission plate 710 to move downward. The gear teeth on the surface of the transmission plate 710 drive the transmission gear 708 to rotate. The transmission gear 708 meshes with the external gear 703 on the side, driving the rotating shaft 701 to rotate. The partition 704 rotates with the rotating shaft 701. The partition 704 unfolds from inside the groove 6 and is placed between the first copper foil and the second copper foil inside the container 2 to separate them. like Figure 9 As shown, an air duct 702 is provided inside the rotating shaft 701. A partition 704 is fixedly connected to the middle of the surface of the rotating shaft 701. A nozzle 705 is fixedly connected inside the partition 704. The air duct 702 and the nozzle 705 are interconnected. The air inside the air duct 702 can be sprayed out from the nozzle 705 to form an air gap between the two copper foils. This prevents the air pressure change between the upper and lower copper foils when the copper foils are picked up, which would cause the lower copper foil to swing. This improves the stability of the stack and prevents the copper foils from deforming during the picking process. like Figure 9 As shown, a sponge pad 706 is fixedly connected to the side wall of the partition 704. A pressure switch 707 is fixedly connected to the middle of the sponge pad 706 on the side wall of the partition 704. An electromagnetic block 712 is fixedly connected to the side of the buffer pad 5 near the ejector spring 711. A power supply is fixedly connected inside the buffer pad 5. One end of the pressure switch 707 is connected to the power supply through a wire, and the other end of the pressure switch 707 is connected to the electromagnetic block 712 in the upper partition mechanism 7 through a wire. The lower end of the transmission plate 710 is made of cast iron. When copper foil is placed on the upper surface of the lower partition 704, the partition 704 will swing downward under the action of the weight of the copper foil. At this time, the pressure switch 707 on the lower surface of the partition 704 presses against the surface of the lower copper foil. At this time, the upper electromagnetic block 712 starts to work. The electromagnetic block 712 attracts the transmission plate 710. Under the action of magnetic attraction, the transmission plate 710 overcomes the elastic force of the ejector spring 711 and moves downward. Furthermore, the bottommost separating mechanism 7 moves downward by pressing the horizontal plate 713 with copper foil, and drives the transmission gear 708 to rotate via the transmission plate 710. The transmission gear 708 meshes with the external gear 703, driving the rotating shaft 701 to rotate. The partition 704 opens and presses on the upper surface of the first copper foil. When the second copper foil is pressed on the upper surface of the bottommost partition 704, the pressure switch 707 at the bottom of the partition 704 is pressed. At this time, the upper layer electromagnetic block 712 is triggered, attracting the transmission plate 710 above it to move downward. The transmission plate 710 drives the transmission gear 708 to rotate. The transmission gear 708 meshes with the external gear 703, driving the rotating shaft 701 to rotate. The partition 704 opens. Similarly, this achieves the opening of the upper partition 704 when each copper foil is placed, separating the lower copper foil from the upper copper foil.

[0024] like Figure 5 As shown, the buffer pad 5 is provided with a connecting mechanism 8 on the side near the separating mechanism 7. An air pipe 9 is fixedly connected to the outer surface of the holding rack 2. The connecting mechanism 8 includes a main air pipe 801. A branch air pipe 802 is fixedly connected to the side of the main air pipe 801. The main air pipe 801 and the air pipe 9 are interconnected. The main air pipe 801 and the branch air pipe 802 are interconnected, so that the air inside the air pipe 9 can enter the interior of the branch air pipe 802. like Figure 6 As shown, a mounting bracket 803 is fixedly connected to the bottom of the air distribution duct 802, a connecting pipe 804 is fixedly connected to the bottom of the mounting bracket 803, a support bracket 805 is fixedly connected to the end of the connecting pipe 804 away from the mounting bracket 803, a connector 806 is fixedly connected to the bottom of the support bracket 805, a conical groove 807 is provided inside the connector 806, and an air hole 808 is provided at the bottom of the mounting bracket 803. The air distribution duct 802 is interconnected with the conical groove 807 through the connecting pipe 804, so that the air inside the air distribution duct 802 enters the interior of the connecting pipe 804 through the air hole 808 and then enters the interior of the conical groove 807, thus realizing air circulation.

[0025] like Figure 11 As shown, a support rod 809 is fixedly connected to the center of the bottom of the mounting bracket 803. A sealing block 810 is fixedly connected to the end of the support rod 809 away from the mounting bracket 803. The conical groove 807 is a groove that is wider at the top and narrower at the bottom. The sealing block 810 is a frustum-shaped block that is wider at the top and narrower at the bottom. The maximum diameter of the upper end of the sealing block 810 is greater than the minimum diameter of the lower end of the conical groove 807, and the maximum diameter of the upper end of the sealing block 810 is less than the maximum diameter of the upper end of the conical groove 807. This allows the sealing block 810 to block the conical groove 807 when it moves upward, stopping the air flow. When the sealing block 810 moves downward, the conical groove 807 can open, allowing air to flow. like Figure 11As shown, a limiting rod 811 is fixedly connected to the upper surface of the support frame 805. A compression spring 812 is wound around the surface of the limiting rod 811. A movable hole is opened on the surface of the mounting frame 803. The limiting rod 811 is inserted into the movable hole. The support frame 805 can move away from the mounting frame 803 under the action of the compression spring 812. The limiting rod 811 constrains the movement range of the support frame 805. The support frame 805 moves horizontally parallel to the mounting frame 803.

[0026] like Figure 11 As shown, the buffer pad 5 is rotatably connected to the horizontal tube 813 on the lower side of the support frame 805. The surface of the horizontal tube 813 is provided with a circular groove. The connector 806 is a conical block, and the diameter of the connector 806 is equal to the diameter of the circular groove. The connector 806 and the circular groove are located on the same vertical plane, so that when the connector 806 moves to the position of the circular groove on the surface of the horizontal tube 813, it can be locked inside the circular groove. At this time, the support frame 805 moves away from the mounting frame 803 under the action of the compression spring 812. like Figure 10 As shown, a flange 814 is fixedly connected to the end of the horizontal pipe 813. The end of the flange 814 away from the horizontal pipe 813 is fixedly connected to the axis of the rotating shaft 701. The horizontal pipe 813 is connected to the air duct 702 inside the rotating shaft 701. When the connector 806 is engaged inside the horizontal pipe 813, air enters the air duct 702 through the horizontal pipe 813 and is sprayed out through the nozzle 705. Furthermore, when the horizontal tube 813 rotates to a horizontal state following the rotating shaft 701, the connector 806 and the circular groove on the surface of the horizontal tube 813 are on the same axis. Under the action of the compression spring 812, the connector 806 and the support frame 805 move away from the mounting frame 803. At this time, the connector 806 is engaged inside the horizontal tube 813, and the sealing block 810 moves upward relative to the conical groove 807, opening the conical groove 807. Air enters the interior of the horizontal tube 813 through the conical groove 807, enters the air duct 702, and is sprayed out through the nozzle 705, forming an air gap between the copper foils.

[0027] like Figure 3 and Figure 4 As shown, the connecting mechanism 8 can be engaged with the separating mechanism 7, and the two are connected to form an air passage after being engaged. The air pipe 9 is connected to the connecting mechanism 8. When copper foil is placed inside the holding rack 2, the separating mechanism 7 can rotate. The air transported by the air pipe 9 enters the separating mechanism 7 through the connecting mechanism 8, and is blown into the gap between two adjacent copper foil sheets through the separating mechanism 7, so that an air gap is formed between each layer of copper foil sheets.

[0028] Working principle: The partition plate 704 of the separating mechanism 7 is housed in the groove 6 of the buffer pad 5, the connector 806 of the connecting mechanism 8 is not engaged with the horizontal tube 813, the sealing block 810 seals the conical groove 807, the air passage is disconnected, the stepper motor 3 drives the push plate 4 to the initial high position, and the holding rack 2 is in the waiting state for loading.

[0029] After the first copper foil is placed in the holding rack 2, its gravity presses down on the horizontal plate 713 of the bottommost separating mechanism 7. The horizontal plate 713 compresses the reset spring 714 and moves downward, driving the corresponding transmission plate 710 to overcome the elastic force of the push-out spring 711 and slide down along the movable groove. The upper part of the transmission plate 710 meshes with the transmission gear 708, driving the transmission gear 708 to rotate, which in turn drives the rotating shaft 701 to rotate in the groove 6 through the external gear 703, causing the partition 704 to unfold from the groove 6 and adhere to the upper surface of the first copper foil. The pressure switch 707 on the side wall of the partition 704 is triggered by the copper foil, which connects the power supply of the electromagnetic block 712 of the upper partition mechanism 7 through the wire. When subsequent copper foils are placed, the above transmission process is repeated, and the upper partition 704 unfolds in sequence to achieve the layer-by-layer separation and alignment of multiple copper foils.

[0030] When the rotating shaft 701 rotates, it drives the horizontal tube 813 to rotate synchronously to a horizontal state through the flange 814, and the circular groove on the surface of the horizontal tube 813 is aligned with the connector 806. Under the elastic force of the compression spring 812, the support frame 805 moves along the limiting rod 811, and the connector 806 is snapped into the circular groove of the horizontal tube 813, thus completing the snapping of the connecting mechanism 8 and the separating mechanism 7. As the sealing block 810 moves down with the support frame 805, the conical groove 807 opens, the air passage is opened, and the air delivered by the air pipe 9 enters the air duct 702 of the rotating shaft 701 through the main air pipe 801, the branch air pipe 802, the connecting pipe 804, the conical groove 807, and the horizontal pipe 813. Finally, it is sprayed out from the nozzle 705 of the partition 704, forming an air gap between adjacent copper foils to prevent the copper foils from sticking together or deforming when handled.

[0031] During transplanting, the stepper motor 3 drives the push plate 4 to rise sequentially, pushing out the copper foil layer by layer. After a single copper foil is removed, the pressure on the corresponding lower partition 704 disappears, the pressure switch 707 is disconnected, and the upper electromagnetic block 712 is de-energized. The transmission plate 710 is reset under the elastic force of the ejector spring 711, the transmission gear 708 is reversed under the action of the torsion spring 709, driving the rotating shaft 701 and the partition plate 704 to be stored back in the groove 6, the horizontal tube 813 is synchronously reversed, the connector 806 is disengaged, the sealing block 810 is reset to seal the conical groove 807, the air passage is disconnected, and the single transplant is completed.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
