Description

Technical Field

[0001] This utility model belongs to the field of lithium battery processing technology, and in particular relates to a nickel sheet processing and packaging device for solid-state lithium batteries. Background Technology

[0002] With the rapid development of new energy technologies, lithium batteries, as high-efficiency energy storage devices, are widely used in many fields. Solid-state lithium batteries have become a research hotspot due to their advantages such as high energy density and strong safety. Nickel sheets, as a key component of lithium batteries, play an important role in connecting electrodes and conducting current inside the battery. Their quality and performance directly affect the overall efficiency of the battery.

[0003] Existing technologies for packaging nickel sheets involve winding the sheets onto a winding roller and then bundling them after a certain amount has been wound. However, due to the relatively soft nature of nickel sheets, they are difficult to adhere tightly to the winding roller without sufficient compression, relying solely on their own weight and friction. Furthermore, some existing nickel sheet packaging devices do not allow for applying pressure to the sheets during use, making it difficult for the sheets to adhere tightly to each other during the winding process. This can lead to inconsistent winding quality, affecting the pass rate and overall quality of lithium battery production. Utility Model Content

[0004] The purpose of this invention is to provide a nickel sheet processing and packaging device for solid-state lithium batteries. This device incorporates a compression mechanism. Specifically, during the nickel sheet winding process, a compression roller is slidably connected to a sliding rod via a slider, which is supported by a spring. As the thickness of the wound nickel sheet increases, the compression roller experiences an outward force. The slider overcomes the spring force and slides along the sliding rod, causing the compression roller to move away from the winding roller. This maintains constant pressure on the nickel sheet, ensuring tight winding. This solves the problem in some existing nickel sheet packaging devices where it is inconvenient to apply pressure to the nickel sheet during use, making it difficult for the nickel sheets to adhere tightly to each other during winding.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a nickel sheet processing and packaging device for solid-state lithium batteries, comprising a support frame and a U-shaped plate. The support frame is equipped with a pressing mechanism and a disassembly mechanism.

[0007] The extrusion mechanism includes grooves formed on the inner walls of the front and rear sides of the support frame. A sliding rod is fixedly connected to the inner wall of each groove, and a slider is slidably connected to the outer wall of each sliding rod. A spring is wound around the outer wall of each sliding rod, with one end of each spring fixedly connected to a corresponding slider and the other end fixedly connected to the inner wall of the corresponding groove. An extrusion roller is rotatably connected between the two sliders. The disassembly mechanism includes a motor fixedly connected to the rear side of the support frame. The support frame provides a support structure for the entire device, ensuring stable installation and operation of all components. The extrusion roller applies pressure to the nickel sheet, ensuring that the nickel sheet is tightly wound onto the winding roller.

[0008] Furthermore, an electric push rod is fixedly connected to the top of the support frame. The output shaft of the electric push rod passes through the top of the support frame and is slidably connected to the support frame. The output shaft of the electric push rod is fixedly connected to a U-shaped plate. Two guide rods pass through the top of the support frame. Both guide rods are slidably connected to the top of the support frame, and the bottom ends of both guide rods are fixedly connected to the U-shaped plate. The electric push rod provides power to the extrusion mechanism and adjusts the height of the extrusion mechanism to adapt to different specifications of nickel sheets and winding rollers. The guide rods ensure the smoothness of the up-and-down movement of the extrusion mechanism.

[0009] Furthermore, the output shaft of the motor is fixedly connected to a rotating shaft one via a coupling. The front end of the rotating shaft one passes through the rear side of the support frame and is rotatably connected to the support frame. A rotating roller is fixedly connected to the front end of the rotating shaft one. The motor provides power for the rotation of the rotating roller to realize the winding of nickel sheets.

[0010] Furthermore, a winding roller is slidably connected to the outer wall of the rotating roller, and several protrusions are fixedly connected to the outer wall of the rotating roller. Several grooves are opened on the inner wall of the winding roller, and several protrusions are slidably connected to the corresponding grooves. The winding roller is installed on the rotating roller and rotates synchronously with the rotating roller, serving as a carrier for winding nickel sheets.

[0011] Furthermore, two fixed plates are fixedly connected to the inner wall of the rotating roller, and a second rotating shaft is rotatably connected to the front side of the rotating roller. The rear end of the second rotating shaft extends to the rear inner wall of the rotating roller, and the rear end of the second rotating shaft passes through the two fixed plates and is rotatably connected to the two fixed plates. The second rotating shaft drives the fixed plates to rotate, thereby controlling the position of the T-shaped block.

[0012] Furthermore, two rotating plates are fixedly connected to the outer wall of the second rotating shaft, and a knob is fixedly connected to the front end of the second rotating shaft. The two rotating plates are located between the two fixed plates.

[0013] Furthermore, several T-shaped grooves are provided on the side of each of the two fixed plates that are close to each other. T-shaped blocks are slidably connected to the inner walls of the T-shaped grooves. Fixed rods are fixedly connected to the side of each T-shaped block that is close to the corresponding rotating plate. The T-shaped blocks slide in the T-shaped grooves and are connected to the rotating plates through the fixed rods. When the rotating plates rotate, the T-shaped blocks move to achieve cooperation and separation with the positioning grooves, thereby completing the installation and fixation of the winding roller.

[0014] Furthermore, both rotating plates are provided with arc-shaped grooves, and the ends of several fixed rods away from the corresponding T-blocks extend to the corresponding arc-shaped grooves and are slidably connected to the inner wall of the corresponding arc-shaped grooves. The inner wall of the winding roller is provided with several positioning grooves, and the tops of several T-blocks extend to the corresponding positioning grooves and are slidably connected to the corresponding positioning grooves. Several T-blocks are slidably connected to the rotating roller. The arc-shaped grooves guide the fixed rods to move, converting the rotation of the rotating plates into the linear motion of the T-blocks.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up an extrusion mechanism, specifically during the nickel sheet winding process, the extrusion roller is slidably connected to the slide bar via a slider, which is supported by a spring. As the thickness of the nickel sheet increases, the extrusion roller is subjected to an outward force, and the slider overcomes the spring force to slide along the slide bar, causing the extrusion roller to move away from the winding roller, thus maintaining extrusion pressure on the nickel sheet at all times and ensuring tight winding.

[0017] 2. By setting up a disassembly mechanism, specifically when installing the winding roller, turning the knob drives the second rotating shaft to rotate, and the rotating plate on the second rotating shaft rotates accordingly. The arc groove on the rotating plate cooperates with the fixed rod, causing the fixed rod to drive the T-shaped block to slide in the T-shaped groove. The T-shaped block moves away from the fixed plate and enters the positioning groove, where the winding roller is installed on the rotating roller through the groove and the protrusion. When disassembling, turning the knob in the opposite direction causes the T-shaped block to disengage from the positioning groove, and the winding roller can be removed. This allows for convenient and quick installation and disassembly of the winding roller, and rapid removal of the wrapped nickel sheets.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-8As shown, this utility model is a nickel sheet processing and packaging device for solid-state lithium batteries, including a support frame 1 and a U-shaped plate 21. The support frame 1 is equipped with a pressing mechanism 2 and a disassembly mechanism 3. The pressing mechanism 2 includes grooves 22 formed on the inner walls of the front and rear sides of the support frame 1. Sliding rods 23 are fixedly connected to the inner walls of both grooves 22, and sliding blocks 24 are slidably connected to the outer walls of both sliding rods 23. Springs 25 are wound around the outer walls of both sliding rods 23. One end of each spring 25 is fixedly connected to the corresponding sliding block 24, and the other end of each spring 25 is fixedly connected to the inner wall of the corresponding groove 22. A pressing roller 26 is rotatably connected between the two sliding blocks 24. The disassembly mechanism 3 includes an electric... The extrusion mechanism 2 ensures the nickel sheet remains tightly adhered during winding. The disassembly mechanism 3 allows for quick removal of the nickel sheet after winding. An electric push rod 27 is fixedly connected to the top of the support frame 1. The output shaft of the electric push rod 27 passes through the top of the support frame 1 and is slidably connected to it. The output shaft of the electric push rod 27 is fixedly connected to a U-shaped plate 21. Two guide rods 28 pass through the top of the support frame 1, both slidably connected to the top of the support frame 1, and their bottom ends are fixedly connected to the U-shaped plate 21. Specifically, during the nickel sheet winding process, the extrusion roller 26 is slidably connected to the slide rod 23 via a slider 24, which is supported by a spring 25. As the thickness of the wound nickel sheet increases, the extrusion roller 26 experiences an outward force. The slider 24 overcomes the spring force of the spring 25 and slides along the slide rod 23, causing the extrusion roller 26 to move away from the winding roller 34, maintaining constant pressure on the nickel sheet to ensure tight winding.

[0032] The output shaft of motor 31 is fixedly connected to a rotating shaft 32 via a coupling. The front end of rotating shaft 32 passes through the rear side of support frame 1 and is rotatably connected to support frame 1. A rotating roller 33 is fixedly connected to the front end of rotating shaft 32. The rotating roller 33 drives the winding roller 34 to rotate, thereby winding and packaging nickel sheets through the winding roller 34. The winding roller 34 is slidably connected to the outer wall of rotating roller 33. Several protrusions 35 are fixedly connected to the outer wall of rotating roller 33. Several grooves 36 are opened on the inner wall of winding roller 34. Several protrusions 35 are slidably connected to the corresponding grooves 36. The protrusions 35 and grooves 36 cooperate to guide and limit the installation position of winding roller 34. Two fixing plates 37 are fixedly connected to the inner wall of rotating roller 33. A rotating shaft 32 is rotatably connected to the front side of rotating roller 33. 9. The rear end of the second rotating shaft 39 extends to the rear inner wall of the rotating roller 33. The rear end of the second rotating shaft 39 passes through two fixed plates 37 and is rotatably connected to the two fixed plates 37. The fixed plates 37 are fixed inside the rotating roller 33 by welding. Two rotating plates 38 are fixedly connected to the outer wall of the second rotating shaft 39. A knob 310 is fixedly connected to the front end of the second rotating shaft 39. The two rotating plates 38 are located between the two fixed plates 37. The two rotating plates 38 are in contact with each other on their respective sides. Several T-shaped grooves 311 are opened on the respective sides of the two fixed plates 37. T-shaped blocks 312 are slidably connected to the inner walls of the several T-shaped grooves 311. Fixed rods 313 are fixedly connected to the sides of the several T-shaped blocks 312 near the corresponding rotating plates 38. The chute 311 guides the movement of the T-block 312, ensuring its stability during movement and providing space for its movement. Both rotating plates 38 have arc-shaped grooves 314. Several fixing rods 313 extend from their ends away from the corresponding T-block 312 to the corresponding arc-shaped grooves 314 and slide in connection with their inner walls. The inner wall of the winding roller 34 has several positioning grooves 315. The tops of several T-blocks 312 extend to the corresponding positioning grooves 315 and slide in connection with them. Several T-blocks 312 are slidably connected to the rotating roller 33. During movement, the T-blocks 312 slide within the T-shaped chute 311 and simultaneously slide to the outside of the rotating roller 33, entering the winding... The positioning groove 315 on the inner wall of the winding roller 34 limits the winding roller 34. By setting up the disassembly mechanism 3, specifically when installing the winding roller 34, the knob 310 is turned to drive the rotating shaft 39 to rotate. The rotating plate 38 on the rotating shaft 39 rotates accordingly. The arc groove 314 on the rotating plate 38 cooperates with the fixing rod 313, so that the fixing rod 313 drives the T-shaped block 312 to slide in the T-shaped slide groove 311. The T-shaped block moves away from the fixing plate 37 and enters the positioning groove 315. The winding roller 34 is installed on the rotating roller 33 through the groove 36 and the protrusion 35. When disassembling, the knob 310 is turned in the opposite direction to make the T-shaped block disengage from the positioning groove, and the winding roller can be removed. The installation and disassembly of the winding roller can be completed conveniently and quickly, and the wrapped nickel sheet can be quickly removed.

[0033] A specific application of this embodiment is as follows: The nickel sheet processing and packaging device for solid-state lithium batteries is mainly used for the winding and packaging of nickel sheets. When the nickel sheets are being wound and packaged, the extrusion roller 26 is slidably connected to the slide rod 23 through the slider 24, and the slider 24 is supported by the spring 25. When the thickness of the nickel sheet winding increases, the extrusion roller 26 is subjected to an outward force. The slider 24 overcomes the elastic force of the spring 25 and slides along the slide rod 23, causing the extrusion roller 26 to move away from the winding roller 34. This ensures that the extrusion roller 26 always maintains a certain extrusion force on the nickel sheet, ensuring that the nickel sheet is tightly wound. At the same time, according to the specifications of the nickel sheet and the winding roller 34, the electric push rod 27 can be activated. Its output shaft pushes the U-shaped plate 21 to move. The U-shaped plate drives the extrusion roller 26 to move up and down as a whole, adjusting the extrusion position. At the same time, the guide rod 28 ensures that the U-shaped plate moves smoothly.

[0034] When motor 31 is turned on, the motor output shaft drives rotating shaft 32 to rotate, and the rotating roller 33 at the front end of rotating shaft 32 rotates accordingly. Since a winding roller 34 is installed on the outer wall of the rotating roller, the rotation of rotating roller 33 can drive the winding roller 34 to rotate synchronously, fixing one end of the nickel sheet to the winding roller 34. As the winding roller 34 rotates, the nickel sheet is gradually wrapped around its outer wall. Finally, the wrapped nickel sheet is bundled to complete the packaging. When installing the winding roller 34, first, the winding roller 34 is placed on the outer wall of rotating roller 33, and at the same time, the protrusion 35 slides into the corresponding groove 36. The installation position of the winding roller 34 is guided and positioned by the protrusion 35 and the groove 36. Then, the knob 310 is rotated in the forward direction, and the knob 310 drives rotating shaft 39 to rotate. The plate 38 rotates accordingly, and the arc groove 314 on the rotating plate 38 cooperates with the fixed rod 313, causing the fixed rod 313 to drive the T-shaped block 312 to slide in the T-shaped slide groove 311. The T-shaped block moves away from the fixed plate 37 and enters the positioning groove 315. At this time, the winding roller 34 can be installed on the rotating roller 33 through the cooperation of the groove 36 and the protrusion 35, as well as the T-shaped block 312 and the T-shaped slide groove 311. The working principle of the knob 310's sinusoidal rotation and reverse rotation is the same. When the knob 310 rotates in the reverse direction, the fixed rod 313, in cooperation with the arc groove 314, causes the T-shaped block 312 to move closer to the fixed plate 37 and disengage from the positioning groove 315. Then, the winding roller 34 can be disassembled by pulling it towards the front end of the rotating roller 33.
