Description

Technical Field

[0001] This utility model relates to the field of lithium battery assembly technology, and in particular to an automatic assembly machine for lithium battery caps. Background Technology

[0002] In the lithium battery production process, the assembly of lithium battery caps is crucial. Traditional lithium battery cap assembly mainly relies on manual operation. Although manual assembly can ensure product quality to a certain extent, it has drawbacks. Therefore, an automatic lithium battery cap assembly machine is needed.

[0003] The automatic lithium battery cap assembly machine is a key piece of equipment used in the lithium battery production process to automate the entire cap assembly process. Its primary function is precise feeding. Through a precision vibratory feeder and feeding track device, the lithium battery caps are transported to the designated assembly station in an orderly and rapid manner, ensuring the accuracy and efficiency of feeding and avoiding errors and speed bottlenecks that occur with manual feeding. Currently, the automatic lithium battery cap assembly machine should achieve full automation. However, in actual operation, the feeding process often requires manual intervention. Although the precision vibratory feeder and feeding track can transport the caps to the designated station in an orderly and rapid manner, a large number of caps often need to be manually poured into the vibratory feeder during the initial feeding. Existing solutions integrate the storage, sorting and feeding functions of the caps into one module. Using the principles of gravity and mechanical transmission, the caps can be automatically arranged and enter the vibratory feeder without the need for manual pre-pouring. While this can achieve automatic feeding to a certain extent, its maximum feeding speed is limited by the speed of gravity and mechanical transmission, which cannot meet the production scenarios with extremely high capacity requirements, thus affecting the improvement of overall production efficiency.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an automatic lithium battery cap assembly machine, comprising a workbench 1. A placement plate 3 is fixedly connected to the top left side of the outer wall of the workbench 1. The placement plate 3 is mainly used to place lithium battery-related components to be assembled. Two robotic arms 5 are fixedly connected to the top left side of the outer wall of the workbench 1. The robotic arms 5 are used by the assembly machine to grasp and transport the components. A fixed block 6 is rotatably connected to the adjacent left side of the two robotic arms 5. The fixed block 6 serves to connect and assist the operation of the grippers 10. Multiple sliding grooves 7 are opened on the left and right sides of the bottom of the inner wall of the fixed block 6. The sliding grooves 7 provide guidance for the movement of the grippers 10. Push rods 8 are fixedly connected to the four sides of the inner wall of the fixed block 6. When it is necessary to control the opening and closing of the grippers 10, the output end of the push rod 8 is activated. The output ends of the multiple push rods 8 are fixedly connected to the connecting plates 9. Multiple grippers 10 are fixedly connected to the adjacent side of the two connecting plates 9. The outer walls of the multiple grippers 10 are slidably connected to the corresponding sliding grooves 7. When the push rod 8 shortens, it drives the connecting plate 9 to move inward. The gripper 10 will close inward along the slide groove 7 to firmly grip the parts. The top and front sides of the worktable 1 are both provided with slide grooves 11. Slider 12s are slidably connected to the inner walls of both slide grooves 11. The function of the slide grooves 11 is to provide a track for the movement of the slider 12, ensuring that the slider 12 can move along a predetermined straight line on the worktable 1. The bottom of the inner walls of both sliders 12 are rotatably connected to moving wheels 14. The moving wheels 14 make the movement of the slider 12 within the slide grooves 11 smoother.

A capping machine 15 is fixedly connected to the top right side of the workbench 1. The capping machine 15 is a key piece of equipment for completing the final assembly of the lithium battery cap. A recycling mechanism 2 is set on the rear side of the workbench 1. The recycling mechanism 2 is used to recycle the generated waste.

[0033] Specifically, on the top left side of the outer wall of the workbench 1, a fixed placement plate 3 is used to place the relevant parts to be assembled. The two robotic arms 5 at the front and rear ends of the top left side of the workbench 1 can move flexibly. The fixed block 6 at the left end of the robotic arm 5 can be adjusted by rotation. Multiple sliding grooves 7 opened on the left and right sides of the bottom of the inner wall of the fixed block 6 cooperate with the gripper 10. The push rod 8 pushes the connecting plate 9, thereby driving the gripper 10 to slide along the sliding groove 7 to grab the lithium battery. The sliding grooves 11 on the front and rear sides of the top of the workbench 1 allow the slider 12 to slide in them. The moving wheel 14 rotatably connected to the bottom of the slider 12, in conjunction with the drive of the micro motor 13 on the front side of the outer wall of the front slider 12, can realize the movement of the slider 12 and the placement box 25. The placement box 25 is used to store the battery items to be assembled. The capping machine 15 on the top right side of the workbench 1 performs the capping operation on the battery after the parts are grabbed and placed in place, completing the automatic assembly process of the cap.

[0034] Reference Figure 6 The recycling mechanism 2 includes a collection box 201. The outer wall of the collection box 201 is located in the middle of the rear side of the outer wall of the workbench 1. The collection box 201 is used to collect waste generated during the automatic assembly of lithium battery caps. A mounting groove 202 is provided at the top rear side of the outer wall of the collection box 201, providing a mounting position for a handle 203. The handle 203 is fixedly connected to the inner wall of the mounting groove 202. When it is necessary to clean the waste in the collection box 201, the operator can hold the handle 203. A ramp 204 is fixedly connected to the top rear side of the inner wall of the collection box 201. The main function of the ramp 204 is... The waste is guided to fall smoothly into the bottom of the collection box 201. The bottom left and right sides of the outer wall of the collection box 201 are fixedly connected with fixing rods 205. The fixing rods 205 are used to fix the collection box 201 stably on the workbench 1. The middle of the rear side of the outer wall of the workbench 1 is provided with a groove 206. The groove 206 provides a placement space for the collection box 201. The bottom left and right sides of the inner wall of the groove 206 are provided with connecting grooves 207. The outer walls of the two fixing rods 205 are engaged with the inner walls of the connecting grooves 207, so that the collection box 201 can be stably installed on the workbench 1.

[0035] Specifically, the outer wall of the collection box 201 is located in the middle of the rear side of the outer wall of the workbench 1. Its function is to collect waste parts or scrap generated during the assembly process. The mounting groove 202 opened at the top of the rear side of the outer wall of the collection box 201 has a built-in handle 203 for easy movement of the collection box 201 by the operator. It is more convenient to remove it for cleaning or put it back in its original position. The inclined plate 204 fixedly connected to the top of the rear side of the inner wall of the collection box 201 can guide objects falling into the collection box 201 to slide to the bottom and prevent them from piling up. To prevent blockage, the fixing rods 205, which are fixedly connected to the bottom left and right sides of the outer wall of the collection box 201, engage with the connecting grooves 207 opened on the bottom left and right sides of the inner wall of the groove 206 in the middle of the rear side of the outer wall of the workbench 1. This allows the collection box 201 to be securely installed on the workbench 1. The fixing rods 205 and the connecting grooves 207 can be disassembled along the connecting grooves 207. When it is necessary to clean the collection box 201, it can be easily separated from the workbench 1. At the same time, the collection box 201 is located on the rear side of the workbench 1 and does not occupy the main operating space.

[0036] Reference Figure 1 , Figure 2 and Figure 4 A controller 16 is fixedly connected to the top right side of the front end of the workbench 1. The controller 16 is electrically connected to the micro motor 13. The controller 16 can send commands to the micro motor 13 to control its operation. Support columns 17 are fixedly connected to the bottom of the workbench 1. Foot pads 18 are fixedly connected to the bottom of the multiple support columns 17. The support columns 17 play a key role in supporting the workbench 1, distributing the weight of the workbench 1 and all the components installed on it evenly to the ground, ensuring the stability of the entire automatic assembly machine. A second groove 26 is opened at the bottom front side of the workbench 1. Fixed columns 19 are fixedly connected to the left and right sides of the inner wall of the second groove 26. Rotating doors 20 are rotatably connected to the outer walls of the two fixed columns 19. The second groove 26 provides installation space for the rotating doors 20 and related structures, and can also be used to store some tools related to the automatic assembly machine.

[0037] Specifically, the controller 16, fixedly connected to the top right side of the front of the workbench 1, is electrically connected to the micro motor 13. The operator sends commands to the micro motor 13 through the controller 16 to adjust its speed, direction and other parameters, thereby precisely controlling the moving speed and direction of the slider 12 and the placement box 25 to meet the precise requirements of the assembly process for material transportation. The support columns 17, fixedly connected around the bottom of the workbench 1, play a key role in supporting the entire assembly machine, distributing the weight of the workbench 1 and the equipment above it evenly to the ground, ensuring the stability of the assembly machine during operation. The foot pads 18, fixedly connected to the bottom of the multiple support columns 17, increase the friction with the ground and prevent the assembly machine from sliding. The groove 26 opened at the bottom front of the workbench 1 has fixed columns 19 fixedly connected to the left and right sides of the inner wall, which are rotatably connected to the rotating door 20. The rotating door 20 rotates around the fixed columns 19. When it is necessary to inspect and maintain the internal space at the bottom of the workbench 1 or store small tools, the rotating door 20 can be opened and closed after the operation is completed, which ensures the sealing of the bottom space and facilitates access and maintenance.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The outer walls of the two rotating doors 20 are each provided with a mounting groove 21. The inner walls of the two mounting grooves 21 are each fixedly connected with a handle 22. The mounting grooves 21, like the mounting groove 202 on the collection box 201, provide a mounting base for specific components. The upper right side of the outer wall of the workbench 1 is fixedly connected with a fixing plate 23. The fixing plate 23 serves to support and fix the hooks 24. The outer wall of the fixing plate 23 is fixedly connected with multiple hooks 24. The hooks 24 can be used to hang tools related to the automatic assembly of lithium battery caps. The top left side of the inner wall of the workbench 1 is fixedly connected with a pneumatic drive 4. The adjacent sides of the two robotic arms 5 are respectively fixedly connected to the output end of the pneumatic drive 4. The pneumatic drive 4 is a device that uses gas pressure to generate power.

[0039] Specifically, the operator can easily open or close the rotating door 20 by holding the handle 22, which improves the convenience of operation. The hook 24 can be used to hang various tools, parts bags or other small items related to assembly work, which effectively utilizes the space around the workbench 1. The pneumatic drive 4 provides power by generating air pressure changes, and the extension and retraction of its output end can precisely control the position and angle of the robotic arm 5.

[0040] Working principle: At the start of the work, the lithium battery to be assembled is placed on the top left side of the outer wall of the workbench 1 on the placement plate 3. The robotic arm 5 at the front and rear ends of the top left side of the workbench 1 moves flexibly under the action of the pneumatic drive 4. The fixed block 6 connected to its left end rotates to adjust its position. The push rod 8 around the inner wall of the fixed block 6 is activated, pushing the connecting plate 9, so that multiple grippers 10 slide along the slide groove 1 7 to grab the lithium battery. At the same time, the slider 12 in the slide groove 2 11 on the front and rear sides of the top of the workbench 1, driven by the micro motor 13 to rotate the moving wheel 14, drives the placement box 25 to move to the designated position. The placement box 25 is used to carry the lithium battery to be assembled. After the robotic arm 5 grabs the part, it moves to the top of the placement box 25 and accurately places the part on the battery. Finally, the capping machine 15 on the top right side of the workbench 1 is activated to cap the battery with the part placed on it.

[0041] Furthermore, the collection box 201 is located on the outer wall of the workbench 1, at the rear center. Waste parts or scrap generated during assembly are placed inside the collection box 201. A handle 203 is installed in the groove 202 at the top rear side of the outer wall of the collection box 201, allowing operators to easily move the collection box 201 by gripping the handle 203 when cleaning is needed. The inclined plate 204 at the top rear side of the inner wall of the collection box 201 guides the falling waste down to the bottom, preventing waste from accumulating at the top of the collection box 201 and affecting subsequent collection. The fixing rods 205 on the bottom left and right sides of the outer wall 01 engage with the connecting grooves 207 on the bottom left and right sides of the inner wall of the groove 206 in the middle of the rear side of the outer wall of the workbench 1, so that the collection box 201 is firmly installed on the workbench 1. When the collection box 201 needs to be cleaned, the operator can separate the fixing rods 205 from the connecting grooves 207 and easily take out the collection box 201 for cleaning. After cleaning, the collection box 201 can be reinstalled back on the workbench 1 by engaging the fixing rods 205 with the connecting grooves 207. This cycle is repeated to efficiently complete the collection and cleaning of waste during the assembly process.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
