[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive and negative electrode materials and a non-aqueous electrolyte solution. In the manufacturing process of lithium batteries, multiple lithium batteries need to be assembled. Through the assembly and series connection of multiple batteries, multiple batteries need to be installed on a splicing board first, with the splicing board serving as the support and positioning basis for multiple batteries. Subsequently, the positive and negative electrodes of multiple batteries are connected in series through electrode plates.

[0003] When placing multiple batteries, the orientation of the batteries needs to be controlled so that the negative terminal of the battery is attached to the splicing plate. At this time, the orientation of the batteries needs to be adjusted before placing them, and the orientation of the batteries needs to be viewed and adjusted after they are removed. This not only makes the operation cumbersome and reduces the production efficiency of lithium batteries, but also increases the labor intensity of the workers. Summary of the Invention

A second cylinder is installed at the end of the first support frame away from the U-shaped positioning frame. The extended end of the second cylinder is connected to a connecting sleeve located inside the first support frame. A movable rod extending to the outside of the connecting sleeve is inserted inside the connecting sleeve. A push plate is installed at one end of the movable rod. One end of the push plate extends to the inside of the U-shaped positioning frame. A limiting rod arranged parallel to the movable rod is installed at the end of the push plate near the connecting sleeve. A limiting block is installed on the outside of the connecting sleeve. The limiting rod extends from one end of the limiting block to the other end of the limiting block. A third telescopic spring is provided at one end of the limiting block to allow the push plate to come down.

[0009] As a further embodiment of the present invention: the detection reversing component further includes a clamping plate installed at one end of the movable rod and located inside the connecting sleeve. A second contact piece is installed at one end of the clamping plate. A first contact piece located on one side of the second contact piece is installed on the inner wall of the connecting sleeve.

[0013] As a further aspect of the present invention: the diameter of the clamping plate is larger than the diameter of the movable rod, and the clamping plate is used to limit the movable rod.

[0014] As a further aspect of the present invention, the thickness of the push plate is less than the length of the protrusion at the positive electrode of the battery.

[0015] This invention also discloses a lithium battery processing and manufacturing method, which uses the above-mentioned lithium battery processing and manufacturing system and includes the following steps:

[0016] S1: First, fix the splicing plate to the top of the tray, then fasten the single battery to the inside of the U-shaped clamping frame. At this time, the arc-shaped plastic clamps limit the left and right directions of the single battery, while the two baffles inside the U-shaped clamping frame limit the two ends of the battery.

[0017] S2: Activate the detection commutation unit. The operation of the detection commutation unit is used to detect the orientation of the positive and negative terminals of the battery. If the positive terminal of the battery is facing upward, the detection commutation unit will not be able to rotate the battery. If the negative terminal of the battery is facing upward, the turntable will rotate 180 degrees under the operation of the detection commutation unit to make the positive terminal of the battery face upward.

[0018] S3: Then, the horizontal and vertical linear modules work together to align the holes on the splicing board with the battery.

[0019] S4: Activate the limiting connector. The operation of the limiting connector causes the baffle to rotate relative to the U-shaped mounting bracket, thereby removing the obstruction to the top and bottom of the battery inside the U-shaped mounting bracket. Then, the operation of the drive module inserts the battery inside the U-shaped mounting bracket into the splicing plate on the tray.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By setting up a detection reversing component, the second cylinder is activated, which drives the U-shaped positioning frame to move. During this process, the connecting sleeve pushes the push plate through the limit block and the third telescopic spring. The connecting sleeve and the push plate move synchronously to bring the push plate into contact with the battery. If the positive terminal of the battery is facing upwards, the push plate will contact the protrusion of the positive terminal of the battery when the second cylinder is fully extended. At this time, the turntable cannot rotate relative to the positioning ring. If the negative terminal of the battery is facing upwards, the push plate will first contact the edge of the battery. Then, as the second cylinder continues to extend, the connecting sleeve will... The battery moves relative to the push plate, at which point the third telescopic spring retracts. When the second cylinder is fully extended, the second contact piece contacts the first contact piece, thereby energizing the first cylinder. The first cylinder then drives the second spur rack to move, causing the second spur rack to rotate the second spur gear 180 degrees clockwise. This causes the turntable to rotate the battery 180 degrees, thus achieving battery flipping. This ensures that the positive terminal of the battery always faces upwards, eliminating the need for workers to adjust the battery's orientation separately. The operation is simple, reducing the workload of workers and improving the efficiency of battery manufacturing and assembly.

[0022] 2. By setting a limiting connector, after adjusting the positive terminal orientation of the battery, the third cylinder is activated. The retraction of the third cylinder causes the push plate to move the U-shaped frame towards the turntable. At this time, the U-shaped frame pulls one end of the diagonal brace, causing the insertion rod to move towards the U-shaped frame. This causes the first spur rack to rotate the first spur gear. At this time, the end of the baffle away from the rotating shaft will swing away from the end away from the battery, thus removing the obstruction at both ends of the battery. Then, by operating the drive module, the battery in the U-shaped mounting bracket can be pushed into the splicing plate on the top of the tray. This allows the battery to be limited without affecting its movement. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0034] Please see Figures 1 to 8 In this embodiment of the invention, a lithium battery processing and manufacturing system includes a body 1, a controller 7 installed on one side of the body 1, a transverse linear module 2 installed on the inner side of the body 1, a longitudinal linear module 3 installed on the top of the transverse linear module 2, a tray 4 provided on the top of the longitudinal linear module 3, a drive module 5 located above the tray 4 and installed on the inner side of the body 1, a mounting frame 12 installed on the bottom of the drive module 5, a positioning ring 6 provided on the bottom of the mounting frame 12, a turntable 8 rotatably connected to the inner side of the positioning ring 6 via a bearing, a U-shaped clamping frame 13 provided at one end of the turntable 8, an arc-shaped plastic clamp 14 installed on the inner side of the U-shaped clamping frame 13, a detection reversing component provided on the outer side of the U-shaped clamping frame 13, and a limit connecting component provided on the inner side of the U-shaped clamping frame 13.

[0035] The limiting connector includes a rotating shaft 10 rotatably connected to the inner side of the U-shaped positioning frame 13. A baffle 11 located on the inner side of the U-shaped positioning frame 13 is provided on the outer side of the rotating shaft 10. Both ends of the rotating shaft 10 extend to the outer side of the U-shaped positioning frame 13. There are two rotating shafts 10, and the two rotating shafts 10 are symmetrically arranged along the transverse central axis of the U-shaped positioning frame 13.

[0036] In this embodiment: First, the splicing plate is fixed to the top of the tray 4. Then, a single battery is clipped onto the inside of the U-shaped mounting bracket 13. At this time, the left and right directions of the single battery are limited by the arc-shaped plastic clamp 14. At the same time, the two baffles 11 on the inside of the U-shaped mounting bracket 13 limit the two ends of the battery. The detection commutation device is activated. The operation of the detection commutation device is used to detect the orientation of the positive and negative terminals of the battery. If the positive terminal of the battery is facing upward, the detection commutation device cannot rotate the battery. If the negative terminal of the battery is facing upward, the turntable 8 will rotate. The battery will rotate 180 degrees under the operation of the detection commutator to make the positive terminal of the battery face upward. Then, the horizontal linear module 2 and the vertical linear module 3 work together to align the socket on the splicing plate with the battery. Then, the limiting connector is activated, and the operation of the limiting connector causes the baffle 11 to rotate relative to the U-shaped card holder 13, so that the top and bottom of the battery inside the U-shaped card holder 13 are no longer obstructed. Then, the operation of the drive module 5 will insert the battery in the U-shaped card holder 13 into the splicing plate on the tray 4.

[0037] Please refer to this carefully. Figure 2 , Figure 3 , Figure 8 The limiting connector also includes a second support frame 24 installed at the end of the turntable 8 away from the U-shaped positioning frame 13. A third cylinder 30 is installed at the end of the second support frame 24 away from the turntable 8. The output end of the third cylinder 30 is connected to a push plate 15 that passes through the turntable 8. A U-shaped frame 40 is installed at one end of the push plate 15. The two ends of the U-shaped frame 40 are rotatably connected to a diagonal brace 41 via a rotating shaft. One end of the diagonal brace 41 is rotatably connected to an insert rod 20 via a rotating shaft. A first spur gear 19 located outside the U-shaped positioning frame 13 is provided at one end of the rotating shaft 10. A guide block 42 is installed on the outer wall of the U-shaped positioning frame 13. The insert rod 20 passes through one end of the guide block 42 to the other end of the guide block 42. A first telescopic spring 21 connected to the insert rod 20 is provided at one end of the guide block 42. A first spur rack 18 that meshes with the first spur gear 19 is fixedly connected to the end of the insert rod 20 away from the diagonal brace 41.

[0038] In this embodiment: After the positive terminal orientation of the battery is adjusted, the third cylinder 30 is activated. The retraction of the third cylinder 30 causes the push plate 15 to move the U-shaped frame 40 toward the turntable 8. At this time, the U-shaped frame 40 pulls one end of the diagonal brace 41, causing the insertion rod 20 to move toward the U-shaped frame 40. This allows the first spur rack 18 to rotate the first spur gear 19. At this time, the end of the baffle 11 away from the rotating shaft 10 will swing away from the end away from the battery. This allows both ends of the battery to be unobstructed. At this time, the operation of the drive module 5 can push the battery in the U-shaped card holder 13 into the splicing plate on the top of the tray 4. This can limit the battery without affecting its movement.

[0039] Please refer to this carefully. Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The detection reversing component includes a first support frame 16 installed on the outside of the U-shaped positioning frame 13. A second cylinder 22 is installed at the end of the first support frame 16 away from the U-shaped positioning frame 13. The extended end of the second cylinder 22 is connected to a connecting sleeve 31 located inside the first support frame 16. A movable rod 32 extending to the outside of the connecting sleeve 31 is inserted inside the connecting sleeve 31. A push plate 33 is installed at one end of the movable rod 32. One end of the push plate 33 extends to the inside of the U-shaped positioning frame 13. A limiting rod 36 arranged parallel to the movable rod 32 is installed at the end of the push plate 33 near the connecting sleeve 31. A limiting block 35 is installed on the outside of the connecting sleeve 31. The limiting rod 36 extends from one end of the limiting block 35 to the other end of the limiting block 35. A third telescopic spring 34 that moves down with the push plate 33 is provided at one end of the limiting block 35.

[0040] The detection reversing component also includes a clamping plate 37 installed at one end of the movable rod 32 and located inside the connecting sleeve 31. A second contact piece 39 is installed at one end of the clamping plate 37. A first contact piece 38 located on one side of the second contact piece 39 is installed on the inner wall of the connecting sleeve 31. A battery compartment 9 is installed on the outer wall of the positioning ring 6. An extension rod 23 located on one side of the second support frame 24 is installed at the end of the turntable 8 away from the U-shaped clamping frame 13. A second spur gear 28 is installed at one end of the extension rod 23. A third support frame 25 located above the extension rod 23 is installed at one end of the positioning ring 6. A first cylinder 17 is installed at the top of the third support frame 25. A connecting frame 27 is connected to the output end of the first cylinder 17. A second telescopic spring 26 connected to the third support frame 25 is provided at the top of the connecting frame 27. A second spur rack 29 meshing with the second spur gear 28 is installed at the bottom of the connecting frame 27.

[0041] One side of the push plate 33 is in contact with the baffle 11. The outer side of the U-shaped positioning frame 13 is provided with a through groove that matches the push plate 33. The center of the turntable 8 is coaxial with the center of the extension rod 23. The center of the second spur gear 28 is coaxial with the center of the extension rod 23. The first contact piece 38 is electrically connected to the battery compartment 9 through a wire. The second contact piece 39 is electrically connected to the first cylinder 17 through a wire. The diameter of the clamping plate 37 is larger than the diameter of the movable rod 32. The clamping plate 37 is used to limit the movable rod 32. The thickness of the push plate 33 is smaller than the length of the positive electrode protrusion of the battery.

[0042] In this embodiment: After the battery is inserted into the U-shaped mounting bracket 13, the second cylinder 22 is activated, which moves the U-shaped mounting bracket 13. During this process, the connecting sleeve 31 pushes the push plate 33 to move through the limiting block 35 and the third telescopic spring 34. The connecting sleeve 31 and the push plate 33 move synchronously to bring the push plate 33 into contact with the battery. If the positive terminal of the battery is facing upward, the push plate 33 will contact the protrusion of the positive terminal of the battery when the second cylinder 22 is fully extended. At this time, the turntable 8 cannot rotate relative to the positioning ring 6. If the negative terminal of the battery is facing upward, the push plate 33 will first contact the edge of the battery. At this time, the second cylinder 22 continues to move. When extended, the connecting sleeve 31 moves relative to the push plate 33. At this time, the third telescopic spring 34 retracts. When the second cylinder 22 is fully extended, the second contact piece 39 will contact the first contact piece 38, thereby energizing the first cylinder 17. The first cylinder 17 will then drive the second spur rack 29 to move, thereby causing the second spur rack 29 to rotate the second spur gear 28 clockwise by 180 degrees. This causes the turntable 8 to rotate the battery by 180 degrees, thus achieving battery flipping. This ensures that the positive terminal of the battery always faces upwards, eliminating the need for operators to adjust the battery orientation separately. The operation is simple, reducing the labor intensity of operators and improving the manufacturing and assembly efficiency of the battery.

[0043] The following describes a lithium battery processing and manufacturing method based on the aforementioned lithium battery processing and manufacturing system, specifically including the following steps:

[0044] S1: First, fix the splicing plate to the top of the tray 4, and then fasten the single battery to the inside of the U-shaped clamp 13. At this time, the arc-shaped plastic clamp 14 limits the left and right directions of the single battery, and the two baffles 11 on the inside of the U-shaped clamp 13 limit the two ends of the battery.

[0045] S2: Activate the second cylinder 22, which drives the U-shaped positioning bracket 13 to move. During this process, the connecting sleeve 31 pushes the push plate 33 to move through the limiting block 35 and the third telescopic spring 34. At this time, the connecting sleeve 31 and the push plate 33 move synchronously to make the push plate 33 contact the battery. If the positive terminal of the battery is facing upward, when the second cylinder 22 is fully extended, the push plate 33 will contact the protrusion of the positive terminal of the battery under the push of the connecting sleeve 31. At this time, the turntable 8 cannot rotate relative to the positioning ring 6. If the negative terminal of the battery is facing upward, the push plate 33 will first contact the edge of the battery. When the second cylinder 22 continues to extend, the connecting sleeve will... 31 moves relative to the push plate 33. At this time, the third telescopic spring 34 retracts. When the second cylinder 22 is fully extended, the second contact piece 39 will contact the first contact piece 38, thereby energizing the first cylinder 17. At this time, the first cylinder 17 will drive the second spur rack 29 to move, thereby causing the second spur rack 29 to drive the second spur gear 28 to rotate 180 degrees clockwise, thereby causing the turntable 8 to rotate the battery 180 degrees. This can achieve the flipping of the battery, so that the positive terminal of the battery always faces upward. This eliminates the need for staff to adjust the orientation of the battery separately, making the operation simple. It not only reduces the labor intensity of the staff, but also improves the manufacturing and assembly efficiency of the battery.

[0046] S3: Then, the horizontal linear module 2 and the vertical linear module 3 work together to align the holes on the splicing board with the battery.

[0047] S4: Start the third cylinder 30. The retraction of the third cylinder 30 causes the push plate 15 to move the U-shaped frame 40 toward the turntable 8. At this time, the U-shaped frame 40 pulls one end of the diagonal brace 41, causing the insertion rod 20 to move toward the U-shaped frame 40. This causes the first spur rack 18 to rotate the first spur gear 19. At this time, the end of the baffle 11 away from the rotating shaft 10 will swing away from the end away from the battery. This will remove the obstruction at both ends of the battery. At this time, the operation of the drive module 5 can push the battery in the U-shaped card holder 13 into the splicing plate on the top of the tray 4. This can limit the battery without affecting its movement.

8. A method for processing and manufacturing a lithium battery, characterized in that, The lithium battery processing and manufacturing system according to any one of claims 1-7 includes the following steps: S1: First, fix the splicing plate to the top of the tray (4), and then fasten the single battery to the inside of the U-shaped card holder (13). At this time, the arc-shaped plastic clamp (14) limits the left and right directions of the single battery, and the two baffles (11) inside the U-shaped card holder (13) limit the two ends of the battery. S2: Start the detection commutator. The positive and negative terminals of the battery are detected by the operation of the detection commutator. If the positive terminal of the battery is facing upward, the detection commutator will not be able to rotate the battery. If the negative terminal of the battery is facing upward, the turntable (8) will rotate 180 degrees under the operation of the detection commutator to make the positive terminal of the battery face upward. S3: Then, the holes on the splicing board are aligned with the battery through the coordinated operation of the horizontal straight module (2) and the vertical straight module (3); S4: Activate the limiting connector. The operation of the limiting connector causes the baffle (11) to rotate relative to the U-shaped card holder (13), thereby removing the obstruction of the top and bottom of the battery inside the U-shaped card holder (13). Then, the operation of the drive module (5) inserts the battery inside the U-shaped card holder (13) into the splicing plate on the tray (4).
