Benefits of technology

[0008] By coordinating components such as the control sleeve, fixed tube, adjusting shaft, movable plate, and connecting shaft, this device successfully solves the technical challenge of traditional core feeding equipment being unable to flexibly adjust the suction speed according to actual usage needs. The device employs the organic combination of the control sleeve, movable plate, connecting shaft, and adjusting shaft to form a highly flexible suction speed adjustment structure. When the suction speed needs adjustment, rotating the control sleeve causes it to move via the connecting shaft, moving the movable plate. This, in turn, causes the movable plate to slide along the adjusting groove, expanding outwards and changing the position of multiple movable holes.

Description

Technical Field

[0001] This utility model relates to the field of lithium battery core feeding technology, and more specifically, it relates to a lithium battery core feeding mechanism. Background Technology

[0002] Against the backdrop of the rapid development of the current lithium battery manufacturing industry, the core feeding process is a key step in the battery production line. Its operational precision and efficiency directly affect the performance and production quality of the final battery products. However, from the perspective of equipment design and production efficiency, existing lithium battery core feeding mechanisms still have technical problems that urgently need to be solved.

[0003] Firstly, most existing lithium battery core loading equipment uses a suction cup adsorption method. While this method offers advantages in terms of ease of operation, its core adsorption system has significant technical flaws. Specifically, the internal structure of the adsorption pipe in traditional adsorption systems is too simple, typically consisting of only a single channel and a suction cup. It lacks a precise control mechanism for airflow speed. This simple structure prevents the adsorption system from adjusting the suction speed according to the different specifications, weights, and materials of lithium battery cores, and from achieving precise control of adsorption strength. When the core material is light, a fixed high suction force may cause the core to deform or be damaged; while when the core is heavy, the suction force may not be sufficient to hold it stably, leading to problems such as core detachment, displacement, or weak adsorption during the loading process. This inability to flexibly adjust the suction speed for different working conditions severely limits the adaptability and efficiency of the equipment, and also increases the product loss rate.

[0004] Secondly, some improved lithium battery core feeding mechanisms have emerged in the market, which superficially achieve flexible adjustment of the suction speed. However, these improved designs still reveal serious stability problems in practical applications: their adjustment structures usually lack precise locking mechanisms and anti-interference designs. When the feeding mechanism is running at high speed, under the influence of various external factors such as vibration and impact, these simply connected adjustment components are prone to loosening, displacement, or control parameter drift. Especially in continuous production, as the equipment runs for a long time, the stability of the adjustment device gradually decreases, and the originally carefully adjusted suction speed parameters inevitably deviate or change. More seriously, on some high-precision, high-requirement lithium battery production lines, small changes in suction speed may cause the core gripping position to shift or the adsorption strength to become unstable, which not only affects the feeding accuracy but may also cause damage or deformation to the core material, thereby affecting the internal structure and performance stability of the battery. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a lithium battery core feeding mechanism to solve the technical problems in the background art where the adjustment structure cannot accurately control the airflow speed, and the adjustment structure lacks a precise locking mechanism and anti-interference design.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery core feeding mechanism, wherein a movable assembly is detachably connected to the top of the base, a movable frame is detachably connected to one side of the movable assembly, a connecting compartment is detachably connected to the side of the movable frame facing away from the movable assembly, a fixed tube is connected to the top of the connecting compartment, a control sleeve is rotatably connected to the end of the fixed tube facing away from the connecting compartment, a connecting tube is rotatably connected to the end of the control sleeve facing away from the fixed tube, a rotating plate is rotatably connected to the outer side of the connecting tube, a rotating hole is formed on one side of the rotating plate, and the outer side of the connecting tube is near the rotating plate. A rotating connecting locking sleeve is provided. Multiple locking frames are fixedly connected to the side of the control sleeve facing away from the fixed tube. Locking rods are slidably connected within each locking frame. A locking plate is fixedly connected to one end of each locking rod. A support rod is fixedly connected to the side of the locking sleeve facing the rotating plate. Multiple locking grooves are formed on the outer wall of the connecting tube. A movable plate is movably connected to the inner side of the control sleeve. A connecting shaft and an adjusting shaft are rotatably connected to the movable plate. One side of the movable plate is rotatably connected to the inner side of the control sleeve via the connecting shaft. Multiple adjusting grooves are formed on one side of the fixed tube. The side of the movable plate on which the adjusting shaft is mounted is slidably connected to the adjusting groove.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] By coordinating components such as the control sleeve, fixed tube, adjusting shaft, movable plate, and connecting shaft, this device successfully solves the technical challenge of traditional core feeding equipment being unable to flexibly adjust the suction speed according to actual usage needs. The device employs the organic combination of the control sleeve, movable plate, connecting shaft, and adjusting shaft to form a highly flexible suction speed adjustment structure. When the suction speed needs adjustment, rotating the control sleeve causes it to move via the connecting shaft, moving the movable plate. This, in turn, causes the movable plate to slide along the adjusting groove, expanding outwards and changing the position of multiple movable holes. This allows for precise adjustment of the flow area inside the fixed tube. This adjustable structure ensures that the device can flexibly adjust the suction speed according to lithium battery cores of different specifications, weights, and materials, precisely controlling the adsorption strength. This effectively avoids deformation and damage to lightweight cores due to excessive suction, while also solving the problem of heavy cores falling off, shifting, or not adsorbing firmly due to insufficient suction. This greatly improves the adaptability and efficiency of the equipment, significantly reduces product loss, and provides more reliable technical support for the core feeding process.

[0009] This multi-locking mechanism, formed by the cooperation of components such as the locking frame, locking sleeve, support rod, support spring, rotating plate, and movable spring, solves the technical defect of insufficient stability in existing improved core feeding mechanisms after air intake speed adjustment. This innovative design integrates a complete locking protection mechanism: after adjustment, the movable spring resets and pulls the locking plate, causing the locking rod to insert into the corresponding locking slot to form a preliminary lock; then, the support spring pushes the locking sleeve to reset, causing the support rod to slide out of the rotating hole; finally, the rotating plate rotates in the opposite direction, causing the rotating hole to move away from the corresponding position of the support rod, and the support rod confines the locking sleeve to one side of the rotating plate, with the inner wall of the locking sleeve... The outer wall of the locking plate forms a secondary limit, ensuring that the locking rod and the locking groove are firmly engaged. This multi-locking mechanism can maintain high stability under the interference of vibration, impact and other factors generated during long-term high-speed operation of the equipment. It effectively prevents the loosening, displacement or drift of the adjustment structure or control parameters, and ensures that the carefully adjusted air intake speed parameters will not deviate or change. Even on high-precision and high-requirement lithium battery production lines, it can ensure the stability of the air intake speed, avoid damage or deformation of the core material caused by the core gripping position deviation or unstable adsorption strength, and effectively protect the stability of the internal structure and performance of the battery.

[0026] Please see Figures 1 to 5A lithium battery core feeding mechanism includes a base 1, a movable assembly 2 detachably connected to the base 1, a movable frame 3 detachably connected to one side of the movable assembly 2, a connecting chamber 4 detachably connected to the side of the movable frame 3 facing away from the movable assembly 2, a fixed tube 5 connected to the top of the connecting chamber 4, a control sleeve 6 rotatably connected to the end of the fixed tube 5 facing away from the connecting chamber 4, a connecting tube 7 rotatably connected to the end of the control sleeve 6 facing away from the fixed tube 5, a rotating plate 8 rotatably connected to the outside of the connecting tube 7, a rotating hole 9 penetrating the rotating plate 8, a locking sleeve 10 rotatably connected to the outside of the connecting tube 7, and a fixed connection on the side of the control sleeve 6 facing away from the fixed tube 5. Multiple locking frames 11 are provided, with locking rods 12 slidably connected inside each locking frame 11. One end of each locking rod 12 is fixedly connected to a locking plate 13. Multiple support rods 14 are fixedly connected to one side of the locking sleeve 10. Multiple locking grooves 15 are provided on the outer side of the connecting tube 7. The locking rods 12 are adapted to the locking grooves 15. A movable plate 16 is movably connected to the inner side of the control sleeve 6. A connecting shaft 17 and an adjusting shaft 18 are rotatably connected to the movable plate 16. One side of the movable plate 16 is rotatably connected to the inner side of the control sleeve 6 through the connecting shaft 17. An adjusting groove 19 is provided on one side of the fixed tube 5. One end of the movable plate 16, on which the adjusting shaft 18 is mounted, is slidably connected to the adjusting groove 19.

[0027] The mounting plate 20 is connected to the bottom of the mobile frame 3, and the suction cup 21 is detachably connected to the bottom of the mounting plate 20.

[0028] The end of the connecting compartment 4 facing away from the fixed tube 5 is detachably connected to the cylinder 22. The output end of the cylinder 22 is connected to the piston rod 23. The bottom of the piston rod 23 is detachably connected to the mounting plate 20. The mounting plate 20 is driven to move up and down precisely by the cylinder 2 and the piston rod 23, so as to achieve precise control of the height of the suction cup 21 and ensure that the pressure of the suction cup 21 when it contacts the core is moderate.

[0029] Both sides of the connecting chamber 4 are connected to connecting pipes 24. The end of the connecting pipe 7 facing away from the rotating plate 8 is connected to a corrugated pipe 25, and the end of the connecting pipe 24 away from the connecting chamber 4 is connected to the corrugated pipe 25. The end of the corrugated pipe 25 facing away from the connecting pipe 4 is connected to the suction cup 21. The use of the corrugated pipe 25 allows the air extraction system to maintain connectivity during movement and adapt to various positional changes, effectively reducing airflow resistance loss caused by air path bends, while improving the system's flexibility and stability.

[0030] In this embodiment, when the device is needed, the moving assembly 2 is first driven, causing it to move the moving frame 3 and the suction cup 21, among other components, to above the core. Then, the cylinder 22 connected to the moving frame 3 is driven synchronously, causing the cylinder 22 to drive the piston rod 23 to push the mounting plate 20 downwards. This causes the mounting plate 20 to lower the suction cup 21, and the suction cup 21 stretches the corrugated pipe 25 connected above. When the suction cup 21 contacts the core, the suction device connected to the input end of the corrugated pipe 25 above the connecting pipe 7 is activated, allowing the suction cup 21 to adhere to the core. Then, the cylinder 22 is driven in the reverse direction, causing it to move the mounting plate 20 and the suction cup 21, among other components, via the piston rod 23. The component moves upward and resets, and the corrugated pipe 25 connected above the suction cup 21 is compressed and reset. At the same time, the suction cup 21 lifts the core and drives the moving assembly 2 in the opposite direction. This causes the moving assembly 2 to move the moving frame 3, the mounting plate 20, and the suction cup 21 on one side in the opposite direction. Simultaneously, the suction cup 21 moves the core, allowing it to be transported to the next station. Then, the above steps are reversed. When the core is transported to the next station, the suction device connected to the input end of the corrugated pipe 25 is turned off, so that the core is no longer attracted, thus achieving progressive feeding. The corrugated pipe 25 connected to the top of the connecting pipe 7 ensures that the movement of the moving assembly 2 does not affect the connection of the pipe, allowing the corrugated pipe 25 to deform accordingly.

[0031] Please see Figures 3 to 5 As a further implementation of the overall device: a support spring 26 is sleeved on the outside of the support rod 14. One end of the support spring 26 is connected to the locking sleeve 10, and the other end of the support spring 26 abuts against the rotating plate 8. This elastic support structure provides the power source for the locking mechanism to reset, ensuring that the locking sleeve 10 can automatically reset to a safe position after adjustment without manual intervention, which greatly improves the ease of operation.

[0032] Both one end of the locking rod 12 and the inner edge of the locking groove 15 are designed with rounded corners. This humanized design significantly reduces the frictional resistance when the locking rod 12 is inserted into and pulled out of the locking groove 15, reduces component wear, extends the service life of the equipment, and also prevents jamming or damage that may be caused by sharp corners, making the air intake speed adjustment operation smoother and more reliable.

[0033] Multiple movable holes 27 are provided on the movable plate 16.

[0034] A movable spring 28 is sleeved on the outside of the locking rod 12. The two ends of the movable spring 28 are connected to the locking plate 13 and the locking frame 11 respectively. This elastic connection structure provides an automatic reset function for the locking mechanism, ensuring that the locking rod 12 can be accurately inserted into the locking groove 15 to form a lock.

[0035] More specifically, when the suction speed needs to be adjusted, first, rotate the rotating plate 8 clockwise. The rotating plate 8 drives the rotating hole 9 to rotate to a position concentric with the support rod 14, pushing the locking sleeve 10. The locking sleeve 10 drives the support rod 14 into the rotating hole 9, and the locking sleeve 10 and the rotating plate 8 cooperate to press the support spring 26, so that the locking sleeve 10 no longer limits the locking plate 13. Then, rotate the control sleeve 6 clockwise. The control sleeve 6 drives the locking frame 11 to rotate clockwise. The locking frame 11 drives the locking rod 12, the locking plate 13, and the movable spring 28 to rotate clockwise. The inner wall of the movable groove presses against one end of the locking rod 12. The locking rod 12 has a rounded corner design at one end and the inner edge of the locking groove 15. One end of the locking rod 12 slides out of the locking groove 15, and the other end of the locking rod 12 drives the locking plate 13 to slide outward. This causes the locking plate 13 to pull the movable spring 28 outward. At the same time, the control sleeve 6 drives the movable plate 16 to move through the connecting shaft 17. This causes the movable plate 16 to drive the adjusting shaft 18 to slide outward along the adjusting groove 19. This causes the movable plate 16 to spread outward, and the movable plate 16 drives multiple movable holes 27 to move outward, thereby changing the internal flow area of ​​the fixed tube 5 and achieving... The purpose of changing the gas flow rate is to change the pumping speed. Once the pumping speed is adjusted appropriately, the control sleeve 6 is stopped from rotating, and the locking frame 11 drives the locking rod 12 and other components to rotate to the position corresponding to the locking groove 15. The movable spring 28 returns to its original position and pulls the locking plate 13, causing the locking plate 13 to slide the locking rod 12 inward. One end of the locking rod 12 slides into the corresponding locking groove 15. Then, the locking sleeve 10 is released, and the support spring 26 pushes the locking sleeve 10 to slide back to its original position. The locking sleeve 10 drives the support rod 14 to slide back to its original position. When the support spring 26 has fully returned to its original position, the support rod 14 no longer inserts into the groove. The rotating plate 8 is rotated in the opposite direction after being inserted into the rotating hole 9. This causes the rotating plate 8 to rotate and reset the rotating hole 9 to a position that does not correspond to the support rod 14. The support rod 14 limits and supports the locking sleeve 10 to one side of the rotating plate 8, preventing the locking sleeve 10 from sliding. The inner wall of the locking sleeve 10 limits the outer wall of the locking plate 13, preventing the locking plate 13 and the locking rod 12 from sliding outward. Then, the locking rod 12 and the locking groove 15 cooperate to limit the locking frame 11, preventing the locking frame 11 and the control sleeve 6 from rotating. This ensures the structural stability after the air extraction speed is adjusted and ensures stable material feeding of the suction cup 21.
