Description

Technical Field

[0001] This utility model relates to the field of battery disassembly technology, specifically to a disassembly device for button batteries. Background Technology

[0002] Button cells, also known as coin cells, are batteries that resemble the size of a small button. They are generally larger in diameter and thinner (compared to cylindrical batteries such as AA batteries on the market). Button cells are categorized by their shape. Corresponding battery categories include cylindrical batteries, square batteries, and irregularly shaped batteries.

[0003] In the laboratory, to analyze the electrolyte composition or observe the positive / negative electrode interface and morphology, button batteries need to be disassembled. The common method is to use pliers to clamp the button battery in the middle and use diagonal pliers to pry open the connection between the positive and negative electrode shells. When disassembling the battery with pliers, it may be impossible to fully control the force or angle of disassembly, which can easily cause the battery shell to crack or deform, thus affecting the observation and analysis of the internal components. To address the above problems, a disassembly device for button batteries is proposed. Utility Model Content

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figure 1-4 As shown, a disassembly device for button batteries includes a chassis 1. Guide posts 3 are fixedly connected to the left and right sides of the top of the chassis 1. A fixing plate 4 is fixedly connected above the two guide posts 3. An upper mold base 5 is detachably connected to the center of the bottom surface of the fixing plate 4. An ejector pin 6 is fixedly connected to the center of the bottom surface of the upper mold base 5. A movable plate 18 is slidably connected between the two guide posts 3 via a sliding sleeve. A fixing seat 7 is detachably connected to the center of the upper surface of the movable plate 18. A lower mold base 8 is detachably connected above the fixing seat 7. A disassembly groove 9 is formed in the center of the upper part of the lower mold base 8. A disassembly step 10 is provided inside the disassembly groove 9. The center of the bottom surface of the disassembly groove 9... A sliding groove 11 is provided, and an ejector block 12 is slidably connected inside the sliding groove 11. A lifting assembly 17 is fixedly installed on the top of the chassis 1 below the moving plate 18. The upper mold base 5 and the lower mold base 8 are on the same central axis. The disassembly groove 9 provides a space for the button battery. The design of the disassembly step 10 cleverly utilizes the feature of the negative electrode protrusion on the edge of the battery. During the process of the ejector pin 6 pressing the middle of the battery, the disassembly step 10 exerts a squeezing effect on the negative electrode protrusion, causing the negative electrode protrusion to lift up, thereby realizing the separation of the positive electrode shell and the negative electrode shell of the battery. This disassembly method is simple and effective, and causes less damage to the battery.

[0021] Specifically, an air passage 13 is provided inside the lower mold base 8 below the sliding groove 11. The air passage 13 is L-shaped and its end extends to the right side of the lower mold base 8. An air nozzle 14 is fixedly connected to the end of the air passage 13 on the right side of the lower mold base 8. The L-shaped design of the air passage 13 makes reasonable use of the internal space of the lower mold base 8. At the same time, the air nozzle 14 is fixedly connected to the right side of the lower mold base 8, which facilitates connection with the ventilation hose 16, ensuring that the gas can smoothly enter the air passage 13 and push the ejector block 12. This structure is simple, reliable and easy to maintain.

[0022] Specifically, an air source component 15 is fixedly installed on the right side of the chassis 1. An air hose 16 is fixedly connected to the output end of the air source component 15. The end of the air hose 16 is connected to the air nozzle 14. A control panel 2 is set on the front side of the chassis 1. The air source component 15 provides a stable air source for the entire ejection system. The air hose 16 realizes a flexible connection between the air source and the air nozzle 14, which facilitates the installation and layout of the equipment and also reduces the vibration and wear that may be caused by rigid connection. The rotation parameters of the servo motor 1706, such as the lifting height and speed of the lifting screw 1704, can be easily set through the control panel 2, making the operation of the equipment simpler and more intuitive.

[0023] Specifically, the lifting assembly 17 includes a mounting shell 1701, which is fixedly connected to the middle of the upper surface of the chassis 1. A worm gear 1702 is rotatably connected inside the mounting shell 1701. The transmission between the worm gear 1702 and the worm 1703 has self-locking properties, which can keep the lifting screw 1704 in the current position when the servo motor 1706 stops rotating, thus ensuring the stability of the moving plate 18 and the lower mold base 8.

[0024] Specifically, a worm gear 1703 is rotatably connected to one side inside the mounting housing 1701. The worm gear 1703 meshes with the worm wheel 1702. A servo motor 1706 that drives the worm gear 1703 to rotate is fixedly installed on the outside of the mounting housing 1701. By precisely controlling the rotation of the worm gear 1703 through the servo motor 1706, the lifting height of the lifting screw 1704 can be precisely controlled, thereby ensuring the accuracy and consistency of the disassembly process.

[0025] Specifically, the worm gear 1702 is threadedly connected to the lifting screw 1704 through a threaded sleeve in the middle. The top of the lifting screw 1704 is fixedly connected to the connecting seat 1705, and the top of the connecting seat 1705 is fixedly connected to the bottom surface of the moving plate 18.

[0026] Specifically, the lower end of the lifting screw 1704 passes through the bottom surface of the mounting housing 1701 and the top wall of the chassis 1 and extends into the interior of the chassis 1. An air pump is installed inside the chassis 1 to provide gas. The air pump provides stable gas to the air source component 15, ensuring that the battery components can be pushed out of the disassembly slot 9 in a timely manner after disassembly, thus improving work efficiency.

[0027] Working principle: Based on the specifications of the button battery to be disassembled, select matching upper mold base 5 and lower mold base 8, and install them on the fixing plate 4 and fixing base 7 respectively. Ensure that the ejector pin 6 is aligned with the center of the disassembly groove 9. Set the rotation parameters of the servo motor 1706 (such as the lifting height of the lifting screw 1704) through the control panel 2, adjust the moving plate 18 to the initial position, and place the button battery with the negative terminal facing up into the disassembly groove 9 of the lower mold base 8. The negative terminal protrusion at the edge of the button battery will contact the disassembly step 10, while the positive terminal will be suspended. Ensure that the ejector pin 6 is aligned with the center of the top of the battery. Start the servo motor 1706 to drive the worm gear 1703 to rotate. Through the worm wheel 1702 and the screw of the lifting screw 1704, the worm gear 1703 rotates. The moving plate 18 moves slowly upward along the guide post 3, and the moving plate 18 drives the lower mold base 8 to rise. The ejector pin 6 gradually presses against the middle of the button battery. As the battery continues to rise, the negative electrode protrusion at the edge of the button battery will be squeezed by the disassembly step 10, thereby separating the positive electrode shell from the negative electrode shell. After separation, the upper mold base 5 and the lower mold base 8 are separated. The air pump is started to introduce air source into the air source component 15. Compressed air enters the air passage 13 through the air hose 16 and the air nozzle 14, and finally sprays out from the sliding groove 11, pushing the ejector block 12 to move upward. The ejector block 12 pushes the disassembled battery components (such as positive electrode shell, negative electrode shell, separator, etc.) out of the disassembly groove 9 for collection.
