Description

Technical Field

[0001] This invention relates to the field of lithium battery production technology, and in particular to a feeding mechanism for a lithium battery PACK production line. Background Technology

[0002] In the production of lithium batteries on a production line, a feeding mechanism is required. Among the many feeding processes, there is a process for feeding semi-finished lithium batteries to move them from one processing step to the next, which necessitates the use of a corresponding feeding mechanism. Existing feeding mechanisms, when feeding semi-finished lithium batteries, merely move the batteries during the feeding process, often failing to complete other processing steps (such as cleaning). Furthermore, when resetting after feeding, they are often in an unloaded state, merely performing a reset without any other functions. This single feeding and unloaded reset results in low time utilization, prolonging the total production time of lithium batteries and reducing production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a feeding mechanism for a lithium battery PACK production line to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A feeding mechanism for a lithium battery PACK production line includes a support frame, an electric slide rail, a sliding seat, a lifting seat, a first electric push rod, a receiving groove, a clamping plate, a first connecting cavity, a second connecting cavity, a hinge shaft, a laser emitter, a roller shaft, a first roller, a servo motor, an adjustment mechanism, an air supply device, a main collecting section, and a secondary collecting section. The electric slide rail is fixed to the rear of the support frame. The sliding seat is slidably connected to the electric slide rail from left to right. The lifting seat is slidably connected to the front of the sliding seat from top to bottom. A vertical support is fixed to the top of the sliding seat. A first electric push rod is fixed at its bottom end to the top end of a lifting seat. The bottom end of the lifting seat has multiple horizontal receiving slots arranged from left to right. A clamping plate is installed at both the front and rear ends of the lifting seat. The upper part of each receiving slot is connected to a first connecting cavity. A second connecting cavity is located at the top of the lifting seat, with its bottom connected to each of the first connecting cavities. The upper part of the second connecting cavity extends through the top end of the lifting seat. Horizontal hinge shafts are fixed to the upper parts of both clamping plates. The two clamping plates are connected via… Two hinge shafts are hinged vertically to the lifting base. Multiple horizontal laser emitters are fixed sequentially from left to right at the opposite ends of the two clamping plates. The laser emitters fixed to the two clamping plates correspond to the front and rear parts of each receiving slot. Multiple sets of horizontal roller shafts are rotatably connected sequentially from left to right at the adjacent ends of the two clamping plates, with each set consisting of two roller shafts. Each set of roller shafts is located below a laser emitter. Each roller shaft is coaxially connected to a first roller. Servo motors are fixed to the right side of each of the two clamping plates. The rotating shafts of the two servo motors are transmitted to the adjacent roller shafts via a transmission mechanism. The roller shafts are also transmitted to each other via a transmission mechanism, ensuring that the rotational speeds of all roller shafts are consistent. An adjustment mechanism is installed between the hinge shafts and the lifting base, allowing the clamping plates to swing up and down around the hinge shafts. An air supply device is fixed to the top of the lifting base, capable of drawing air from the second connecting cavity. The lifting base is equipped with a main collecting section, and the support frame is equipped with a secondary collecting section.

[0006] Based on the above technical solution, the adjustment mechanism includes a second electric push rod, a transmission groove, a crank, and a guide rod. A vertical second electric push rod is fixed at each of the left and right ends of the lifting seat. A horizontal transmission groove is fixed at the bottom of the push rods of the two second electric push rods. A crank is radially fixed at each of the hinge shafts. A guide rod is fixed at the end of each crank away from the hinge shaft. The two transmission grooves are interlocked with the guide rods on the left and right sides of the lifting seat.

[0007] Based on the above technical solution, the air supply device includes an outer shell, a first pipe, a second pipe, a stepper motor, an axial flow fan, an inlet pipe, an exhaust pipe, and a partition. A vertical outer shell is fixed to the top of the lifting seat. The left end of the outer shell is fixedly connected to the first pipe, and the right end is fixedly connected to the second pipe. The left part of the first pipe is connected to the second connecting cavity. A horizontal stepper motor is fixed to the front end of the outer shell. A horizontal axial flow fan is coaxially fixed to the shaft of the stepper motor. The left part of the axial flow fan is fixedly connected to the inlet pipe, and the right part of the axial flow fan is fixedly connected to the exhaust pipe. Arc-shaped partitions are fixed at the edges of the ends of the inlet pipe and the exhaust pipe, respectively. The partitions are in contact with and fit against the inner wall of the outer shell. The first pipe and the inlet pipe can communicate with each other. When the first pipe is connected to the inlet pipe, the second pipe can communicate with the exhaust pipe.

[0008] Based on the above technical solution, the main collection part includes a third connecting cavity, a storage tank, an upper filter screen, a first one-way valve, a second one-way valve, a third one-way valve, an auger shaft, auger blades, gears, and baffles. The lifting seat has a third connecting cavity, the left and right parts of which are connected to the second connecting cavity. A horizontal storage tank is located at the front end of the lifting seat, connected to the middle of the third connecting cavity. The left side of the storage tank connected to the second connecting cavity is covered and fixed with an upper filter screen. A first one-way valve is installed on the upper part of the second connecting cavity, connected to the second connecting cavity. The left and right sides of the third connecting cavity are sequentially equipped with… Equipped with a No. 2 one-way valve and a No. 3 one-way valve, which are respectively connected to a No. 3 connecting chamber, the No. 2 and No. 3 one-way valves are located on the left and right sides of the storage tank, respectively. The No. 1 one-way valve only allows fluid to pass from left to right, while the No. 2 and No. 3 one-way valves only allow fluid to pass from right to left. The lifting seat is rotatably connected to a horizontal auger shaft, and the auger shaft is coaxially fixed with auger blades and gears. The auger blades are intermittently inserted into the storage tank. The front of the lifting seat is slidably connected to a vertical baffle, which tends to slide down the lifting seat under the action of gravity and can seal the front of the storage tank.

[0009] Based on the above technical solution, the auxiliary collection part includes a mounting frame, a collection cylinder, a collection hopper, a mounting plate, a second roller, a rack, a support plate, a dual-axis motor, a brush shaft, brush bristles, a support cylinder, a lower filter screen, and an exhaust fan. A mounting frame is fixed to the front of the support frame, a collection cylinder is fixed to the front of the mounting frame, and a collection hopper is fixed to the bottom of the mounting frame. The bottom of the collection cylinder is directly above the collection hopper. A vertical mounting plate is fixed to the upper part of the collection cylinder. Multiple second rollers are rotatably connected to the upper part of the mounting plate from left to right. The upper part of the outer circumferential wall of each second roller can roll and rub against the upper part of the baffle. A horizontal rack is fixed to the rear of the mounting frame. When the upper part of the outer circumferential wall of the second roller rolls and rubs against the upper part of the baffle, the rack can mesh with a gear. A... Two support plates are provided, each with a dual-axis motor fixed to its middle section. Multiple brush shafts are rotatably connected to each support plate. Brush bristles arranged in a roller-like pattern are fixed to the upper part of each brush shaft and the upper part of the dual-axis motor's rotating shaft. The brush shafts are connected and driven by a transmission mechanism. The brush shafts rotatably connected to the two support plates converge in a ridge-like shape. When the rack and gear mesh, the brush bristles can contact the laser emitter and the first roller. At this time, the through-hole at the front of the storage tank is directly above the through-hole at the top of the collection cylinder. Vertical support cylinders are inserted vertically into the bottom of the collection hopper. The support cylinders are fastened to the collection hopper by fasteners. A lower filter screen is fixedly enclosed in the middle of the support cylinder, and a fan is fixed to the bottom of the support cylinder.

[0010] Based on the above technical solution, the support frame is also fixed with a controller, a ranging sensor, and a recognition camera. The electric slide rail, the first electric push rod, the laser emitter, the servo motor, the second electric push rod, the stepper motor, the axial flow fan, the dual-axis motor, the exhaust fan, the controller, the ranging sensor, and the recognition camera are electrically connected. The controller is connected to an external power supply. When the electric slide rail is energized, it can drive the sliding seat to slide left and right. When the first electric push rod is energized and extends, it can drive the lifting seat to slide up and down along the sliding seat. When the servo motor is energized and rotates, it can drive each roller shaft to rotate at the same speed through the transmission mechanism. When the second electric push rod is energized and extends, it enables the hinge shaft to rotate in both directions via the transmission groove, the guide rod, and the crank. When the stepper motor is energized and rotates in both directions, it drives the axial flow fan to rotate up and down. When the axial flow fan is energized and rotates, it draws air in through the air inlet pipe and discharges it through the exhaust pipe. When the dual-axis motor is energized and rotates, it drives the brush shaft to rotate through the transmission mechanism. When the exhaust fan is energized and rotates, it draws air from above and discharges it downwards. The distance sensor can measure the left and right horizontal distances of the left end of the sliding seat. The recognition camera can identify the position of the lifting seat relative to the support frame.

[0011] Compared with the prior art, the present invention has the following advantages: In the process of carrying cylindrical lithium batteries using the receiving tank, the present invention can rotate the cylindrical lithium batteries using a first roller while transporting them. At the same time, with the cooperation of an axial flow fan, the cylindrical lithium batteries can be rotated and suction-cleaned simultaneously, resulting in good cleaning effect. Furthermore, the use of a laser emitter can clean the positive and negative electrodes of the lithium batteries, thereby saving some subsequent processes and improving the utilization rate of time.

[0012] During the no-load reset process, the second roller allows the baffle to release the storage tank, and the rack and pinion mechanism rotates the auger blades to discharge dust and other particles collected in the storage tank. The rotation of the dual-axis motor allows the brush to clean the laser emitter and the first roller, facilitating stable operation in subsequent work. The axial flow fan and exhaust fan work together to clean the first and second connecting chambers and the receiving tank, and the collection bucket collects the swept-out dust particles, reducing adverse effects on the cylindrical lithium batteries being transported and the production environment.

[0013] By discharging dust and other particulate matter from the storage tank during reset and collecting it using a collection hopper, the hassle of dedicated cleaning is reduced, time is saved, and time utilization and production efficiency are improved. Attached Figure Description

The electric slide rail 2 is fixed to the rear of the support frame 1. The sliding seat 3 is slidably connected to the electric slide rail 2 from left to right. The lifting seat 4 is slidably connected to the front of the sliding seat 3 from top to bottom. A vertical first electric push rod 5 is fixed to the top of the sliding seat 3. The bottom end of the push rod of rod 5 is fixed to the top end of the lifting seat 4. Multiple horizontal receiving slots 6 are sequentially opened from left to right on the bottom end of the lifting seat 4. A clamping plate 7 is installed on both the front and rear parts of the lifting seat 4. The upper part of each receiving slot 6 is connected to a first connecting cavity 8. A second connecting cavity 9 is opened on the upper part of the lifting seat 4. The bottom of the second connecting cavity 9 is connected to each of the first connecting cavities 8. The upper part of the second connecting cavity 9 extends through the top end of the lifting seat 4. Horizontal hinge shafts 10 are fixed to the upper parts of the two clamping plates 7. The two clamping plates 7 are hinged vertically to the lifting seat 4 via the two hinge shafts 10. Multiple horizontal laser emitters 11 are sequentially fixed from left to right on the opposite ends of the two clamping plates 7. The laser emitters 11 fixed by the two clamping plates 7 correspond to the front and rear parts of each receiving slot 6, respectively. Multiple sets of horizontal roller shafts 12 are rotatably connected from left to right at the adjacent ends of the two clamping plates 7, with each set consisting of two roller shafts 12. Each set of roller shafts 12 is located below the laser emitter 11. Each roller shaft 12 is coaxially rotatably connected to a roller 13. Servo motors 14 are fixed to the right side of the two clamping plates 7, and the shafts of the two servo motors 14 are connected to the adjacent roller shafts 12 via a transmission mechanism. This transmission structure is a known prior art, such as belt drive, where the roller shafts 12 are connected to each other via a transmission mechanism. The transmission structure is a known existing technology, such as belt drive. It is necessary to make the rotation speed of each roller shaft 12 tend to be consistent, so that when the outer circumferential wall of the first roller 13 rolls and rubs against the outer circumferential wall of the cylindrical lithium battery, the first roller 13 can stably drive the cylindrical lithium battery to rotate. An adjustment mechanism 15 is installed between the hinge shaft 10 and the lifting seat 4. The adjustment mechanism 15 can make the clamping plate 7 swing up and down around the hinge shaft 10 as the axis. The top of the lifting seat 4 is fixed with an air supply device 16. The air supply device 16 can draw air from the second connecting cavity 9. The lifting seat 4 is equipped with a main collection part 17, and the support frame 1 is equipped with a secondary collection part 18.

[0025] The adjustment mechanism 15 includes a second electric push rod 19, a transmission groove 20, a crank 21, and a guide rod 22. The lifting seat 4 has a vertical second electric push rod 19 fixed at each of its left and right ends. The bottom of the push rods of the two second electric push rods 19 are respectively fixed with horizontal transmission grooves 20. Each hinge shaft 10 is radially fixed with a crank 21. The end of each crank 21 away from the hinge shaft 10 is respectively fixed with a guide rod 22. The two transmission grooves 20 are respectively interlocked with the guide rods 22 on the left and right sides of the lifting seat 4.

[0026] The air supply device 16 includes an outer shell 23, a first pipe 24, a second pipe 25, a stepper motor 26, an axial flow fan 27, an inlet pipe 28, an exhaust pipe 29, and a partition 30. A vertical outer shell 23 is fixed to the top of the lifting seat 4. The left end of the outer shell 23 is fixedly connected to the first pipe 24, and the right end is fixedly connected to the second pipe 25. The left part of the first pipe 24 is connected to the second connecting cavity 9. A horizontal stepper motor 26 is fixed to the front end of the outer shell 23. A horizontal axial flow fan 27 is coaxially fixed to the shaft of the stepper motor 26. The left part of the axial flow fan 27 is fixedly connected to the inlet pipe 28, and the right part of the axial flow fan 27 is fixedly connected to the exhaust pipe 29. 9. Arc-shaped baffles 30 are fixed at the edges of the ends of the intake pipe 28 and the exhaust pipe 29, respectively. The baffles 30 are in contact with and fit against the inner wall of the outer shell 23, thereby maintaining good airtightness and ensuring good negative pressure effect after the axial flow fan 27 rotates. At the same time, it indirectly ensures that the position of the axial flow fan 27 relative to the outer shell 23 is stable. The first pipe 24 and the intake pipe 28 can be connected to each other. When the first pipe 24 is connected to the intake pipe 28, the second pipe 25 can be connected to the exhaust pipe 29.

[0027] The main collection section 17 includes a third connecting cavity 31, a storage tank 32, an upper filter screen 33, a first one-way valve 34, a second one-way valve 35, a third one-way valve 36, an auger shaft 37, auger blades 38, gears 39, and a baffle 40. The lifting seat 4 has a third connecting cavity 31, the left and right parts of which are connected to the second connecting cavity 9. The front end of the lifting seat 4 has a horizontal storage tank 32, which is connected to the middle of the third connecting cavity 31. The left part of the storage tank 32, where it connects to the second connecting cavity 9, is covered and fixed with an upper filter screen 33. A first one-way valve 34 is installed on the upper part of the second connecting cavity 9, and the first one-way valve 34 is connected to the second connecting cavity 9. The left and right parts of the third connecting cavity 31, from left to right, are equipped with a second one-way valve 35 and a third one-way valve 36. One-way valves 35 and 36 are respectively connected to the third connecting chamber 31. One-way valves 35 and 36 are located on the left and right sides of the storage tank 32. One-way valve 34 only allows fluid to pass from left to right, while one-way valves 35 and 36 only allow fluid to pass from right to left. The lifting seat 4 is rotatably connected to a horizontal auger shaft 37. The auger shaft 37 is coaxially fixed with auger blades 38 and gears 39. The auger blades 38 are intermittently inserted into the storage tank 32. A vertical baffle 40 is slidably connected to the front of the lifting seat 4. Under the action of gravity, the baffle 40 tends to slide down along the lifting seat 4 and can seal the front of the storage tank 32, thereby preventing air leakage from this point and reducing the negative pressure effect formed in the receiving tank 6.

[0028] The secondary collection section 18 includes a mounting frame 41, a collection cylinder 42, a collection hopper 43, a mounting plate 44, a second roller 45, a rack 46, a support plate 47, a dual-axis motor 48, a brush shaft 49, brush bristles 50, a support cylinder 51, a lower filter screen 511, and an exhaust fan 52. The mounting frame 41 is fixed to the front of the support frame 1, and the collection cylinder 42 is fixed to the front of the mounting frame 41. The collection hopper 43 is fixed to the bottom of the mounting frame 41. The bottom of the collection cylinder 42 is directly above the collection hopper 43. A vertical mounting plate 44 is fixed to the upper part of the collection cylinder 42. Multiple second rollers are rotatably connected to the upper part of the mounting plate 44 from left to right. The roller 45, the upper part of the outer circumferential wall of the second roller 45, can roll and rub against the upper part of the baffle 40, so that when the baffle 40 moves left and right with the lifting seat 4 and rolls and rubs against the second roller 45, the second roller 45 can stably support the baffle 40. The mounting frame 41 has a horizontal rack 46 fixed at the rear. When the upper part of the outer circumferential wall of the second roller 45 rolls and rubs against the upper part of the baffle 40, the rack 46 can mesh with the gear 39. The bottom of the mounting frame 41 has two support plates 47 fixed, and the middle part of the two support plates 47 is respectively fixed with a dual-axis motor 48. The two support plates 47 are rotatably connected to multiple Each brush shaft 49 and the upper part of the shaft of the dual-axis motor 48 are respectively fixed with brush bristles 50 arranged in a roller shape. The brush shafts 49 are connected and driven by each other and by the shaft of the dual-axis motor 48 through a transmission mechanism. This transmission structure is a known prior art, such as belt drive. The brush shafts 49 rotatably connected to the two support plates 47 are clustered together in a ridge shape. When the rack 46 meshes with the gear 39, the brush bristles 50 can contact the laser emitter 11 and the first roller 13, so that the brush bristles 50 can move circumferentially as they follow the rotation of the shafts of the brush shafts 49 and the dual-axis motor 48. It can clean the laser emitter 11 and the first roller 13. When the rack 46 meshes with the gear 39, the through-hole at the front of the storage tank 32 is directly above the through-hole at the top of the collection cylinder 42. Vertical support cylinders 51 are inserted into the bottom of the collection hopper 43. The support cylinders 51 are fastened to the collection hopper 43 by fasteners. The vertically inserted support cylinders 51 and fastened to the collection hopper 43 by fasteners can be easily disassembled, so as to facilitate the dumping of dust and other particles intercepted above the lower filter screen 511. The lower filter screen 511 is closed and fixed in the middle of the support cylinder 51. A fan 52 is fixed at the bottom of the support cylinder 51.

[0029] The support frame 1 is also fixed with a controller 53, a ranging sensor 54, and a recognition camera 55. The controller 53 is a known prior art technology, such as an industrial control computer. The electric slide rail 2, the first electric push rod 5, the laser emitter 11, the servo motor 14, the second electric push rod 19, the stepper motor 26, the axial flow fan 27, the dual-axis motor 48, the exhaust fan 52, the controller 53, the ranging sensor 54, and the recognition camera 55 are electrically connected. The controller 53 is connected to an external power supply. When the electric slide rail 2 is energized, it can drive the sliding seat 3 to slide left and right. When the first electric push rod 5 is energized and extends, it can drive the lifting seat 4 to slide up and down along the sliding seat 3. When the servo motor 14 is energized and rotates, it can drive each roller through the transmission mechanism. Shaft 12 rotates at the same speed. When the second electric push rod 19 is energized and extends, it can cause the hinge shaft 10 to rotate in both directions through the transmission groove 20, the guide rod 22 and the crank 21. When the stepper motor 26 is energized and rotates in both directions, it can drive the axial flow fan 27 to rotate up and down. When the axial flow fan 27 is energized and rotates, it can draw air through the air inlet pipe 28 and discharge it from the exhaust pipe 29. When the dual-axis motor 48 is energized and rotates, it can drive the brush shaft 49 to rotate through the transmission mechanism. When the exhaust fan 52 is energized and rotates, it can draw air from above and discharge it downwards. The distance sensor 54 can measure the left and right horizontal distance of the left end of the sliding seat 3. The recognition camera 55 can identify the position of the lifting seat 4 relative to the support frame 1.

[0030] The working principle of this invention is as follows: When in use, the electric slide rail 2 can be controlled to make the sliding seat 3 slide left and right, thereby transporting the semi-finished lithium battery left and right. Assuming that the semi-finished lithium battery is transported from right to left for loading, and the return trip is from left to right, the specific process is as follows.

[0031] First, the controller 53 controls the sliding seat 3 to move to the rightmost part of the electric slide rail 2. At this time, the distance sensor 54 can sense the position of the sliding seat 3, which is called state a. When state a is reached, the air inlet pipe 28 is connected to the first pipe 24, the axial flow fan 27 is in a high-speed rotation state, the second electric push rod 19 extends the push rod, so that the two clamping plates 7 can be opened upward through the transmission groove 20, the smooth rod 22, the crank 21 and the hinge shaft 10. At the same time, the first electric push rod 5 extends the push rod to the maximum extent, so that the receiving groove 6 is in the lowest state relative to the support frame 1. At this time, the axial flow fan 27 forms a negative pressure at the air inlet pipe 28, so that a negative pressure zone is formed in each receiving groove 6 through the first pipe 24, the third connecting cavity 31 and the first connecting cavity 8, which can then suck up the cylindrical lithium battery below and put it into the receiving groove 6. Then the controller 53 automatically executes the next action. First, the second electric push rod 19 retracts, allowing the two clamping plates 7 to converge downwards via the transmission groove 20, the guide rod 22, the crank 21, and the hinge shaft 10 until each roller shaft 12 is horizontal. Then, the controller 53 automatically controls the axial flow fan 27 to rotate at a low speed, while the two servo motors 14 rotate at the same speed. The low-speed rotation of the axial flow fan 27 reduces the negative pressure effect, allowing the cylindrical lithium battery to fall along the receiving groove 6 until it is lifted by each set of first rollers 13. At this point, the outer circumference of the first roller 13 rolls and rubs against the outer circumference of the cylindrical lithium battery. As the servo motors 14 rotate, they drive the roller shafts 12 to rotate via the transmission mechanism, thus allowing the first rollers 13 to rotate the cylindrical lithium battery they support, thereby adjusting the cylindrical shape. The circumferential angle of the cylindrical lithium battery relative to the receiving tank 6 facilitates the suction of dust and other particles from various parts of the outer circumference of the cylindrical lithium battery. The dust and other particles enter the first connecting cavity 8, the third connecting cavity 31 and the storage tank 32 and are intercepted by the upper filter screen 33. Then, the first electric push rod 5 is completely retracted, so that the lithium battery reaches the highest position relative to the support frame 1. Then, the controller 53 controls the electric slide rail 2 to move the sliding seat 3 to the left. During the movement of the sliding seat 3, the laser emitter 11 can be powered on for a period of time to etch and clean the positive and negative electrodes of the cylindrical lithium battery. When the sliding seat 3 moves to the leftmost part of the electric slide rail 2, the distance measured by the ranging sensor 54 to the left end of the sliding seat 3 reaches the minimum value, that is, the state b is reached.Subsequently, controller 53 automatically controls the first electric push rod 5 to fully extend, during which servo motor 14 stops rotating. Then, it controls the second electric push rod 19 to extend, causing clamping plate 7 to unfold upwards, thus allowing the cylindrical lithium battery in receiving slot 6 to be completely removed, achieving the loading of cylindrical lithium batteries. Next, controller 53 automatically controls the second electric push rod 19 to retract, making roller shaft 12 horizontal. Then, it controls the first electric push rod 5 to fully retract. Then, controller 53 controls the electric slide rail 2 to move, causing sliding seat 3 to slide to the right. When sliding seat 3 moves to the middle of support frame 1, recognition camera 55 recognizes that lifting seat 4 has reached the left and right positions of support frame 1 and... When the height position meets the standard, state c is reached. When the recognition camera 55 detects that the left and right position of the lifting seat 4 relative to the support frame 1 no longer meets the standard, state c is released. In this state, the controller 53 controls the first electric push rod 5 to extend, thereby causing the lifting seat 4 to move down. This causes the baffle 40 to be blocked by the second roller 45, releasing the seal on the storage tank 32. The rack 46 will mesh with the gear 39. As the lifting seat 4 moves to the right, the gear 39 will rotate, thereby driving the auger shaft 37 and auger blades 38 to rotate. This allows the dust and other particles intercepted by the upper filter screen 33 in the storage tank 32 to be conveyed forward and fall into the collection cylinder. Within state 42, when initially entering state c, controller 53 will automatically control stepper motor 26 to rotate half a revolution, thereby connecting pipe 24 to exhaust pipe 29 and pipe 25 to intake pipe 28. When ending state c, controller 53 will automatically control stepper motor 26 to reverse half a revolution, thereby resetting. Then, with the operation of axial flow fan 27, outside air will be drawn in through pipe 25 and filled into pipe 24, and then discharged through connecting chamber 9, one-way valve 34 and connecting chamber 8, thereby blowing the dust and other particles remaining in connecting chamber 9, one-way valve 34 and connecting chamber 8 downwards into receiving tank 6. In state c, dual-axis motor 48 will... The rotating mechanism drives the brush shaft 49 to rotate, causing the brush bristles 50 to clean the laser emitter 11 and the first roller 13. At the same time, the exhaust fan 52 rotates, creating a negative pressure above the collection hopper 43. This allows the dust and other particles entering the collection cylinder 42 and exiting the receiving tank 6 to be drawn out and transported downwards until they are intercepted by the lower filter screen 511. This cleans the dust and other particles in the lifting seat 4. When the c state is disengaged, the gear 39 and rack 46 disengage and stop rotating. The partition 30 re-seals the storage tank 32 under the action of gravity. As the sliding seat 3 moves to the right, it will eventually reach the a state.

[0032] In summary, by cycling through the three states a, b, and c in sequence, the feeding process for cylindrical lithium batteries can be repeatedly completed.

For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
