Description

Technical Field

[0001] This utility model relates to the field of copper strip production, and in particular to a device for synchronously applying adhesive to both sides of nickel-plated copper strips to prevent dislocation of electrode tabs. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very high environmental standards. With the development of science and technology, lithium batteries have become the mainstream.

[0003] In existing technologies, lithium batteries can be broadly divided into lithium-ion batteries and lithium metal batteries. Battery tabs are an important component of lithium-ion batteries. Battery tabs are mainly used to lead the positive and negative electrodes out of the cell. Generally, the positive electrode of lithium-ion battery tabs is made of aluminum alloy, and the negative electrode is made of nickel. The negative electrode can also be made of copper plated with nickel.

[0004] However, the nickel-plated copper strips on the tabs need to be cut before use, and then the surface of the nickel-plated copper strips on the tabs needs to be protected by an adhesive applicator. Most of the existing adhesive applicators can only apply adhesive to one side of the copper strip at a time, which is inefficient. In addition, the adhesive applicator cannot be adjusted according to different copper strips, which makes it unsuitable. Utility Model Content

[0005] To overcome the problems that most existing adhesive application devices can only apply adhesive to one side of the copper strip at a time, resulting in low work efficiency, and that the adhesive application devices cannot be adjusted according to different copper strips, thus lacking applicability.

[0006] The technical solution of this utility model is as follows: a double-sided synchronous adhesive applicator with nickel-plated copper strip for anti-dislodgement, comprising a device support, a shelf movably connected to the inner wall of the device support, electric clamps movably connected to both ends of the inner wall of the shelf, a rack at the top of the shelf, a drive assembly connected to the top of the rack, the drive assembly being used for connection between the shelf and the device support, a connecting frame fixedly connected to the rear end of the device support, adhesive rollers movably connected to both ends of the inner wall of the connecting frame, an adjustment assembly threadedly connected to the center of the two adhesive rollers, the adjustment assembly being used for connection between the connecting frame and the two adhesive rollers; the drive assembly includes a second servo motor, and a transmission gear fixedly connected to the output end of the second servo motor. The second servo motor is the drive mechanism for the transmission gear. One end of the transmission gear extends above the rack. When the second servo motor drives the transmission gear to rotate, the second servo motor, in conjunction with the transmission gear and rack, causes the shelf to slide on the inner wall of the device support. The adjustment component includes a first servo motor. The output end of the first servo motor is fixedly connected to a transmission rod. The first servo motor is the drive mechanism for the transmission rod. One end of the first servo motor is rotatably connected to a first lead screw. Both ends of the first lead screw extend to the outside of the adhesive roller and are rotatably connected to the connecting frame. When the first servo motor drives the transmission rod to rotate, the first servo motor, in conjunction with the transmission rod and the first lead screw, causes the two adhesive rollers to move relative to each other on the inner wall of the connecting frame.

[0007] Preferably, the inner side of the shelf is hollow, and the two adhesive rollers are located at the upper and lower ends of the copper strip, respectively. This allows for double-sided adhesive application of the copper strip using the two adhesive rollers, improving the working efficiency of the device. Furthermore, the positions of the two adhesive rollers can be adjusted according to the copper strip of different thicknesses using a first servo motor in conjunction with a transmission rod and a first lead screw, thereby improving the applicability of the device.

[0008] Preferably, the inner wall of the device support is provided with a sliding groove, and both sides of the shelf are provided with inserts. One end of the insert is inserted into the inner side of the sliding groove, and the shelf is slidably connected to the device support through the inserts.

[0009] Preferably, the adhesive roller is provided with displacement seats on both sides, one end of which extends to the inside of the connecting frame, and the adhesive roller is movably connected to the connecting frame through the displacement seats.

[0010] Preferably, a rotary motor is provided on the inner side of the displacement seat, and the rotary motor is connected to the adhesive roller through a coupling.

[0011] Preferably, a control panel is fixedly connected to one side of the device bracket, and the control panel is electrically connected to the electric clamp, the first servo motor, the second servo motor, and the rotary motor.

[0012] Preferably, one end of the transmission rod is provided with a bevel gear, and the transmission rod is connected to the first lead screw through the bevel gear.

[0013] Preferably, the first lead screw is a double-threaded lead screw with symmetrical threads at both ends. The two ends of the first lead screw are threadedly connected to two displacement seats. When the transmission rod drives the first lead screw to rotate, the first lead screw causes the two displacement seats to move relative to each other inside the connecting frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. The anti-dislodgement electrode tab nickel-plated copper strip double-sided synchronous adhesive application device has a hollow structure inside the shelf and two adhesive rollers located at the upper and lower ends of the copper strip, which can apply adhesive to both sides of the copper strip through the two adhesive rollers, thereby improving the working efficiency of the device.

[0016] 2. The anti-dislodgement electrode tab nickel-plated copper strip double-sided synchronous adhesive application device improves the applicability of the device, and can adjust the position of the two adhesive rollers according to the copper strip of different thicknesses through the first servo motor in conjunction with the transmission rod and the first lead screw, thereby improving the applicability of the device.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 This utility model provides an embodiment of a double-sided synchronous adhesive applicator for anti-dislodgement nickel-plated copper strips, comprising a device support 1, a shelf 2 movably connected to the inner wall of the device support 1, electric clamps 4 movably connected to both ends of the inner wall of the shelf 2, a rack 9 at the top of the shelf 2, a drive assembly connected to the top of the rack 9 for connecting the shelf 2 and the device support 1, a connecting frame 5 fixedly connected to the rear end of the device support 1, adhesive rollers 6 movably connected to both ends of the inner wall of the connecting frame 5, and the center of the two adhesive rollers 6... The position is threadedly connected to an adjustment assembly, which is used to connect the connecting frame 5 and the two adhesive rollers 6. The drive assembly includes a second servo motor 8, the output end of which is fixedly connected to a transmission gear 10. The second servo motor 8 is the drive mechanism for the transmission gear 10. One end of the transmission gear 10 extends above the rack 9. When the second servo motor 8 drives the transmission gear 10 to rotate, the second servo motor 8, in conjunction with the transmission gear 10 and the rack 9, causes the shelf 2 to slide on the inner wall of the device support 1. The adjustment assembly includes a first servo motor 7, the output end of which is fixedly connected to a transmission rod 11. The first servo motor 7 is the drive mechanism for the transmission rod 11. One end of the first servo motor 7 is rotatably connected to a first lead screw 12. Both ends of the first lead screw 12 extend to the outside of the adhesive rollers 6 and are rotatably connected to the connecting frame 5. When the first servo motor 7 drives the transmission rod 11 to rotate, the first servo motor 7, in conjunction with the transmission rod 11 and the first lead screw 12, causes the two adhesive rollers 6 to move relative to each other on the inner wall of the connecting frame 5. Thus, when the cut copper strip is placed inside the shelf 2... Then, the copper strip is clamped by the electric clamping block 4, and then the second servo motor 8, in conjunction with the transmission gear 10, drives the shelf 2 to move towards the adhesive roller 6. Since the inner side of the shelf 2 is hollow and the two adhesive rollers 6 are located at the upper and lower ends of the copper strip respectively, the copper strip can be glued on both sides by the two adhesive rollers 6, which improves the applicability of the device. Moreover, the position of the two adhesive rollers 6 can be adjusted by the first servo motor 7 in conjunction with the transmission rod 11 and the first lead screw 12 according to the different thicknesses of the copper strip, which improves the applicability of the device.

[0025] Please see Figures 2-3 In this embodiment, the inner wall of the device support 1 is provided with a sliding groove, and both sides of the shelf 2 are provided with insert blocks 3. One end of the insert block 3 is inserted into the inner side of the sliding groove. The shelf 2 is slidably connected to the device support 1 through the insert block 3. Both sides of the adhesive roller 6 are provided with displacement seats 13. One end of the displacement seat 13 extends to the inner side of the connecting frame 5. The adhesive roller 6 is movably connected to the connecting frame 5 through the displacement seat 13. A rotary motor is provided inside the displacement seat 13. The rotary motor is connected to the adhesive roller 6 through a coupling. A control panel 14 is fixedly connected to one side of the device support 1. The control panel 14 is electrically connected to the electric clamp 4, the first servo motor 7, the second servo motor 8, and the rotary motor.

[0026] Please see Figures 4-5 In this embodiment, a bevel gear is provided at one end of the transmission rod 11. The transmission rod 11 is connected to the first lead screw 12 through the bevel gear. The first lead screw 12 is a double-threaded lead screw. The threads at both ends of the first lead screw 12 are symmetrical to each other. The two ends of the first lead screw 12 are threadedly connected to two displacement seats 13. When the transmission rod 11 drives the first lead screw 12 to rotate, the first lead screw 12 causes the two displacement seats 13 to move relative to each other inside the connecting frame 5.

[0027] When in operation, the power is turned on and the device is started. After the cut copper strip is placed inside the shelf 2, the copper strip is clamped by the electric clamping block 4. Then, the second servo motor 8, in conjunction with the transmission gear 10, drives the shelf 2 to move towards the adhesive roller 6. When the shelf 2 is at the bottom of the adhesive roller 6, the rotary motor inside the displacement seat 13 drives the adhesive roller 6 to apply adhesive to the surface of the copper strip. Since the inside of the shelf 2 is a hollow structure and the two adhesive rollers 6 are located at the upper and lower ends of the copper strip respectively, the copper strip can be coated with adhesive on both sides by the two adhesive rollers 6, which improves the working efficiency of the device. In addition, the position of the two adhesive rollers 6 can be adjusted by the first servo motor 7 in conjunction with the transmission rod 11 and the first lead screw 12 according to the different thicknesses of the copper strip, which improves the applicability of the device.

[0028] Through the above steps, the inner side of the shelf 2 is hollow, and the two adhesive rollers 6 are located at the upper and lower ends of the copper strip, respectively. Thus, the copper strip can be glued on both sides by the two adhesive rollers 6, which improves the working efficiency of the device. Moreover, the position of the two adhesive rollers 6 can be adjusted by the first servo motor 7 in conjunction with the transmission rod 11 and the first lead screw 12 according to the different thicknesses of the copper strip, which improves the applicability of the device. This solves the problem that most existing adhesive application devices can only apply adhesive to one side of the copper strip at a time, resulting in low working efficiency, and the adhesive application device cannot be adjusted according to different copper strips, resulting in insufficient applicability.
