Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and particularly to a conveying device and a conveying method for cylindrical battery production. Background Art

[0002] With the progress of battery technology, especially the development of cylindrical batteries towards larger sizes and higher energy densities, traditional conveying devices have been difficult to meet the requirements of efficient and precise production. The production of cylindrical batteries mainly relies on automated production lines to achieve large-scale production through processes such as winding and encapsulation.

[0003] However, during the process of battery production, generally, battery cases are centrally poured into a storage compartment, and then the battery cases are successively put into the production process through a conveyor belt. Subsequently, a robotic arm installs a battery core assembly into the battery case. However, during the transmission process, if the orientation of some battery cases is incorrect, they need to be removed and re-introduced into the production line, or through a dual production line, different-oriented battery cases are separately processed. This will greatly increase the production cost, and when a battery case is removed, there will be a vacancy at this position, affecting the subsequent processing efficiency of the battery.

[0014] In addition, the present invention adopts the following technical solution, a conveying method for a conveying device for cylindrical battery production, comprising the following steps: S1. First, the battery shell is transferred on the transfer rack and regulated by the adjustment plate and the baffle. Then, when the positive electrode block is not oriented correctly, it will conflict with the rotating rod, so that the detection structure can determine whether the orientation of the battery shell is correct.

[0015] S2. Then the push plate will move a distance with the battery shell with incorrect direction. During the movement, the gear rod will no longer be inserted into the inside of the slot, so that the sliding plate will release the restriction, so that the sliding plate drives the push plate to push the battery shell with incorrect direction to the upper end of the bogie.

[0016] S3. When the battery shell with incorrect direction is pushed to the upper end of the bogie, the clamping seat will partially cover the positive block, and at the same time, the magnetic block pair will adsorb the positive block. Then the winding wheel 2 rotates to pull the rotating plate 2 to rotate. During the rotation of the rotating plate 2, the battery shell with incorrect direction will be turned over, so that the direction of the battery shell is turned to the correct direction.

[0017] S4. Finally, when the battery shell is flipped in the incorrect direction, as the bogie pushes, the battery shell will conflict with the inner wall of the limit plate, and then the push-back structure will push the battery shell back to the inside of the limit frame where the battery shell was originally taken out.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The positive electrode block is pushed into the cavity of the sliding groove through the displacement plate, so that the detection structure can detect the orientation of the battery case. When it is detected that the orientation of the battery case is incorrect, the pushing structure will release the elastic potential energy of the spring on the outer wall of the positioning rod, so that the push plate can push the battery case with incorrect orientation to the upper end of the bogie. Then, the second rotating rod drives the steering structure to move towards the battery case at the upper end of the bogie. Then, the positive electrode block is adsorbed and positioned by the magnetic attraction block. Then, during the process of the steering structure moving towards the limiting plate, the second wire reel rotates to drive the connecting rope to pull the second rotating plate, so as to correct the battery case with incorrect orientation. Then, the corrected battery case is transmitted into the pushing-back structure through the bogie. By the adsorption force of the second magnetic attraction block on the battery case, it is judged whether there is a battery case inside each limiting frame. Then, the spring on the outer wall of the second positioning rod releases the elastic potential energy, so as to push the steered battery case back into the corresponding limiting frame, solving the problem that a single production line cannot remove the battery cases with incorrect orientation. At the same time, it can also put the corrected battery cases back into the corresponding baffles again, preventing the problem of subsequent production vacancies caused by the vacancy in some limiting frames, and improving the working efficiency of the battery production line.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 - 11 The present invention provides a technical solution: a conveying device for cylindrical battery production, comprising a transmission frame 1, a bogie 2 is installed on one side of the transmission frame 1, and a conveyor belt is installed on the outer side walls of the transmission frame 1 and the bogie 2. A plurality of limit frames 3 are installed at equal intervals on the conveyor belt of the outer side wall of the transmission frame 1, and a battery shell 6 can be placed inside each limit frame 3. A positive electrode block 46 is installed at one end of the battery shell 6. A baffle 4 is installed on the side of the transmission frame 1 away from the bogie 2, and a slide groove 42 is provided on the side of the baffle 4 close to the transmission frame 1, and the slide groove 42 and the positive electrode block 46 can be slidably connected. A positioning plate 5 is also installed on the side of the transmission frame 1 away from the baffle 4, and the positioning plate 5 can contact one end of the battery shell 6; An inspection structure is provided in the cavity of the chute 42, which can determine the orientation of the battery shell 6 by making contact with the positive electrode block 46. A push-out structure is installed on the side of the transmission frame 1 away from the bogie 2, which can cooperate with the detection structure to push the battery shell 6 out; One end of the bogie 2 close to the position adjusting plate 5 is provided with a limit seat 22. The limit seat 22 is located at the upper end of the bogie 2. One end of the limit seat 22 away from the transmission rack 1 is connected with a movable plate 23 in a transverse sliding manner. One end of the movable plate 23 away from the limit seat 22 is provided with a steering structure, which can steer the battery case 6. On one side of the bogie 2 away from the limit seat 22, a pushing-back structure is installed, which can push the battery case 6 after being steered by the steering structure back into the limit frame 3.

[0023] Among them, the pushing-out structure includes a motor 11. The motor 11 is fixedly connected to one side of the transmission rack 1 away from the bogie 2. The output end of the motor 11 is fixedly connected with a threaded rod 10. A support seat 7 is screwed on the outer side wall of the threaded rod 10. The side surface of the support seat 7 is connected with a first sliding plate 8 in a sliding manner. At the lower end of the first sliding plate 8 close to the transmission rack 1, a pushing plate 21 is installed, and the pushing plate 21 can abut against the positive electrode block 46. Two steering wheels 13 are installed on one side of the support seat 7 away from the transmission rack 1. One end of the lower side surface of the support seat 7 is rotatably connected with a first wire winding wheel 12, and the first wire winding wheel 12 is fixedly connected with the threaded rod 10. A traction wire 14 is sleeved on the outer side wall of the first wire winding wheel 12, and the traction wire 14 bypasses the two steering wheels 13 and is fixedly connected with the first sliding plate 8.

[0024] Specifically, refer to Figure 4 , a first positioning rod 9 is installed at the upper end of the first sliding plate 8. A spring is sleeved on the outer side wall of the first positioning rod 9, and the spring is located between the first sliding plate 8 and the support seat 7. When the motor 11 drives the threaded rod 10 and the first wire winding wheel 12 to rotate, the first wire winding wheel 12 will wind up the traction wire 14. Through the steering of the pulling direction of the traction wire 14 by the two steering wheels 13, the first sliding plate 8 is pulled to move away from the transmission rack 1, so that the spring on the outer side wall of the first positioning rod 9 stores elastic potential energy. At the same time, restricted by the detection structure, the elastic potential energy cannot be released. Meanwhile, the motor 11 can drive the threaded rod 10 to rotate forward and backward continuously. When rotating forward, the push plate 21 will move a certain distance synchronously with the limit frame 3. At the same time, the winding wheel 12 will release the traction wire 14 on its outer wall. However, the first sliding plate 8 is restricted from moving at this time. When rotating backward, the push plate 21 will reset, making it synchronize with the next limit frame 3 again. During the reset process, the winding wheel 12 will wind up the traction wire 14, so that the released traction wire 14 is wound around the outer wall of the winding wheel 12 again. This process repeats. During the synchronous movement of the push plate 21 and the limit frame 3, if the detection structure detects that the orientation of the battery case 6 is incorrect, the restriction on the first sliding plate 8 will be released. The spring sleeved on the positioning rod 9 releases elastic potential energy, and the battery case 6 is pushed to the upper end of the bogie 2 through the push plate 21. Then the motor 11 drives the threaded rod 10 to rotate reversely, so that the push plate 21 and the support seat 7 reset. When the threaded rod 10 rotates reversely, the winding wheel 12 will also move synchronously, thereby winding up the traction wire 14, pulling the first sliding plate 8 back to its original position, and being restricted from moving again by the detection structure.

[0025] Among them, the detection structure includes a first rotating rod 15. The first rotating rod 15 is rotatably connected in the cavity of the sliding groove 42. A connecting seat 16 is fixedly connected to the side of the baffle 4 away from the transmission frame 1. A first gear 17 is rotatably connected to the outer wall of the connecting seat 16, and the first gear 17 is fixedly connected to the first rotating rod 15. A rack 18 is slidably connected to the outer wall of the connecting seat 16. A plurality of teeth are installed on the upper surface of the rack 18, and the teeth can mesh with the first gear 17.

[0026] Among them, a slot 20 is opened on the side of the support seat 7 close to the connecting seat 16, and the slot 20 penetrates the side surface of the first sliding plate 8. The slot 20 can be slidably connected to the rack 18. A reset spring 19 is installed at the lower end of the rack 18.

[0027] Specifically, the axis of the first rotating rod 15 is a damping axis. When the return spring 19 pushes the first gear 17 to rotate and the first rotating rod 15 returns to its original position, it will return slowly. When the limiting frame 3 carries the battery case 6 with the wrong direction through the chute 42, the positive electrode block 46 will come into contact with the first rotating rod 15 and push the first rotating rod 15 to rotate. During the rotation of the first rotating rod 15, it will drive the first gear 17 to rotate together. During the rotation of the first gear 17, it will push the return spring 19 and the toothed rod 18 to move away from the slot 20. At this time, if the threaded rod 10 rotates to drive the support base 7 to move away from the connecting seat 16, the toothed rod 18 will disengage from the cavity of the slot 20 on the first sliding plate 8, so that the first sliding plate 8 will no longer be restricted from moving. At this time, during the synchronous movement of the push plate 21 and the limiting frame 3, the spring on the outer wall of the first positioning rod 9 will push the first sliding plate 8 towards the bogie 2, and at the same time, the push plate 21 will also push the push plate 21 with the wrong direction towards the position of the bogie 2 until the battery case 6 is pushed to the upper surface of the bogie 2 and abuts against the movable plate 23. At the same time, during the sliding of the battery case 6, the battery case 6 can play an auxiliary limiting role.

[0028] Among them, the steering structure includes a first rotating plate 24, which is fixedly connected to one side of the movable plate 23 close to the transmission frame 1. The end of the first rotating plate 24 far from the movable plate 23 is rotatably connected to a second rotating plate 25. A clamping seat 26 is installed on one side of the second rotating plate 25 close to the limiting seat 22. Two magnetic attraction blocks 27 are symmetrically slidably connected to the inner wall of the clamping seat 26, and the magnetic attraction blocks 27 can adsorb the outer wall of the positive electrode block 46.

[0029] Among them, a steering shaft 29 is fixedly connected to the side of the second rotating plate 25 far from the clamping seat 26. A second winding wheel 33 is rotatably connected to the side of the movable plate 23 far from the first rotating plate 24. A connecting rope 30 is sleeved on the outer wall of the second winding wheel 33, and the other end of the connecting rope 30 is fixedly connected to the steering shaft 29. An inclined slider 28 is fixedly connected to one side of the magnetic attraction block 27, and the inclined slider 28 is slidably connected to the second rotating plate 25. A pushing groove 31 is opened on the side of the first rotating plate 24 far from the limiting seat 22, and the pushing groove 31 can abut against the inclined slider 28.

[0030] Among them, a second rotating rod 35 is fixedly connected to the outer wall of the limiting seat 22, the output end of the second rotating rod 35 is fixedly connected to the movable plate 23, a rack 32 is fixedly connected to the side of the limiting seat 22 close to the movable plate 23, a second gear 34 is fixedly connected to the upper end of the second winding wheel 33, and the second gear 34 meshes with the rack 32.

[0031] Specifically, the connection between the first rotating plate 24 and the second rotating plate 25 is a torsion spring shaft. Refer to Figure 6, when the battery case 6 moves to the upper end of the bogie 2 and abuts against the side surface of the movable plate 23, the second rotating rod 35 will push the first rotating plate 24 and the second rotating plate 25 to move together in the direction of the limit seat 22. Then, the clamping seat 26 will come into contact with the positive electrode block 46. At the same time, when the positive electrode block 46 contacts the clamping seat 26, the inclined slider 28 will, through its own suction force, make the outer side wall of the positive electrode block 46 magnetically attracted together. Refer to Figure 5 , where the rack 32 only has teeth in the direction away from the limit seat 22. When the second rotating plate 25 moves in the direction of the limit seat 22, the second gear 34 will not mesh with the rack 32. Then, when the second rotating rod 35 pushes the first rotating plate 24 and the second rotating plate 25 to move the battery case 6 with incorrect direction in the direction away from the limit seat 22, at this time, the second gear 34 will mesh with the rack 32, causing the second gear 34 to start rotating. During the rotation of the second gear 34, the second wire reel 33 will also rotate. During the rotation of the second wire reel 33, the connecting rope 30 will be driven to pull the second magnetic attraction block 39. During the process of the steering shaft 29 being pulled, the second rotating plate 25 will rotate around the torsion spring shaft between it and the first rotating plate 24. During the rotation of the second rotating plate 25, it will also drive the battery case 6 with incorrect direction to rotate together, so as to change the direction of the battery case 6. One end of the inclined slider 28 close to the steering shaft 29 extends to the outer surface of the second rotating plate 25, and the side of the inclined slider 28 close to the steering shaft 29 is an inclined side. When the second rotating plate 25 fits with the first rotating plate 24, the inclined side of the inclined slider 28 will abut against the groove wall of the pushing groove 31, so that the inclined slider 28 is pushed to move away from the steering shaft 29. At the same time, the first magnetic attraction block 27 will also be driven to release the adsorption of the positive electrode block 46. At this time, the thrust generated by the bogie 2 for transmitting the battery case 6 will push the battery case 6 in the direction of the pushing-back structure.

[0032] Among them, the pushing-back structure includes a connecting plate 36, the connecting plate 36 is fixedly connected to the side surface of the support seat 7, a bracket 37 is fixedly connected to one end of the connecting plate 36 away from the support seat 7, a positioning ring 40 is fixedly connected to the upper end of the bracket 37, a second magnetic attraction block 39 is slidably connected in the cavity of the positioning ring 40, a second sliding plate 41 is fixedly connected to one end of the second magnetic attraction block 39 away from the transmission rack 1, and a sliding rod 38 is fixedly connected to one side of the lower end of the second sliding plate 41 close to the transmission rack 1, and the sliding rod 38 is slidably connected to the bracket 37.

[0033] Among them, a limiting plate 55 is fixedly connected to the upper surface of one end of the bracket 37 far from the second sliding plate 41. A second positioning rod 47 is fixedly connected to the side surface of the limiting plate 55. A reset ring 45 is slidably connected to the outer side wall of the second positioning rod 47. A rotating shaft rod 44 is fixedly connected to the side of the bogie 2 far from the transmission rack 1. Two connecting rods 43 are symmetrically installed on the outer side wall of the rotating shaft rod 44. The lower connecting rod 43 is rotatably connected to the sliding rod 38. One side of the upper connecting rod 43 close to the reset ring 45 is rotatably connected to a third magnetic attraction block 50, and the third magnetic attraction block 50 is slidably connected to the limiting plate 55. A spring is installed between the limiting plate 55 and the reset ring 45.

[0034] Among them, a sliding groove 51 is formed in the side surface of the reset ring 45. A resisting rod 48 is slidably connected to the inner side wall of the sliding groove 51. A conical magnetic block 49 is slidably connected to one side of the reset ring 45 close to the third magnetic attraction block 50, and the conical magnetic block 49 can abut against the resisting rod 48. A spring is fixedly connected between the conical magnetic block 49 and the reset ring 45. An electric slide rail 52 is arranged on the upper surface of the limiting plate 55. An inclined pushing block 53 is slidably connected to the cavity of the electric slide rail 52, and the inclined pushing block 53 can abut against the resisting rod 48. One side of the inclined pushing block 53 is a bevel edge. When the bevel edge of the inclined pushing block 53 contacts the resisting rod 48, the resisting rod 48 will be pushed to slide upward.

[0035] Specifically, the bracket 37 is fixedly connected to the support seat 7 through a connecting plate 36, so that during the movement of the support seat 7, the bracket 37 and the limiting plate 55 will also move synchronously, so that when the pushing-back structure pushes the rotated battery case 6 back into the original limiting frame 3 again, the battery case 6 will not be flipped due to the different moving speeds of the pushing-back structure and the limiting frame 3. For each limiting frame 3 passing through the position of the positioning ring 40, if there is a battery case 6 inside the limiting frame 3, the second magnetic attraction block 39 will be adsorbed and move in the direction of the transmission rack 1. During the movement of the second magnetic attraction block 39, the sliding rod 38 will be driven to slide in the direction of the transmission rack 1 through the second sliding plate 41. During the sliding of the sliding rod 38, the two connecting rods 43 will be driven to rotate around the rotating shaft rod 44. During the rotation of the connecting rods 43, the third magnetic attraction block 50 will be pushed to move in the direction of the conical magnetic block 49, so that the conical magnetic block 49 is attracted by the magnetic attraction force. When there is no battery case 6 inside the limiting frame 3, the second magnetic attraction block 39 will reset. Refer to Figure 7 , where a spring for resetting is installed between the second sliding plate 41 and the positioning ring 40. Then when the second magnetic attraction block 39 resets, the sliding rod 38 will also reset. At this time, the third magnetic attraction block 50 will move away from the conical magnetic block 49. When there is a rotated battery case 6 on the side of the reset ring 45 close to the transmission rack 1, the conical magnetic block 49 will be attracted and move in the direction of the rotated battery case 6. Refer to Figure 10, the hypotenuse of the conical magnet 49 abuts against the abutting rod 48. At this time, the conical magnet 49 will push the abutting rod 48 to slide upward. When the abutting rod 48 slides upward, it will cause the abutting rod 48 to disengage from the inclined push block 53. At this time, the spring on the outer wall of the positioning rod two 47 will release elastic potential energy, thereby pushing the rotated battery case 6 to re-insert into the inside of the limiting frame 3 at the corresponding position. At the same time, the magnetic attraction block two 39 magnetically attracts and positions the battery case 6 inserted back into the inside of the limiting frame 3 again, preventing the battery case 6 from deflecting and improving the stability of the device.

[0036] A conveying method for a conveying device used in cylindrical battery production, comprising the following steps: S1. First, the battery case 6 is conveyed on the conveying frame 1, and the battery case 6 is regularized by the position adjusting plate 5 and the baffle 4. Then, when the positive electrode block 46 faces in the incorrect direction, it will abut against the rotating rod one 15, so that the detection device can judge whether the orientation of the battery case 6 is correct.

[0037] S2. Then, the push plate 21 will move a certain distance along with the battery case 6 with the incorrect direction. During the movement, the toothed rod 18 no longer inserts into the inside of the slot 20, so that the sliding plate one 8 is released from the restriction, and thus the sliding plate one 8 drives the push plate 21 to push the battery case 6 with the incorrect direction to the upper end of the turning frame 2.

[0038] S3. When the battery case 6 with the incorrect direction is pushed to the upper end of the turning frame 2, the clamping seat 26 will partially sleeve the positive electrode block 46, and at the same time, the magnetic attraction block one 27 adsorbs the positive electrode block 46. Then, the winding wheel two 33 rotates to pull the rotating plate two 25 to rotate. During the rotation of the rotating plate two 25, it will drive the battery case 6 with the incorrect direction to flip, so that the orientation of the battery case 6 becomes correct.

[0039] S4. Finally, after the battery case 6 with the incorrect orientation is flipped, with the push of the turning frame 2, the battery case 6 will abut against the inner wall of the limiting plate 55, and then through the pushing-back structure, the battery case 6 is pushed back into the inside of the limiting frame 3 where the battery case 6 was originally taken out.

[0040] Working principle: The battery cases 6 are sequentially conveyed through the limit frames 3 on the conveying rack 1. During the conveying process, each battery case 6 is regularized through the cooperation of the position-adjusting plate 5 and the baffle 4. When the battery case 6 is in the wrong orientation, the positive electrode block 46 will enter the cavity of the sliding groove 42, so that the detection structure can detect the orientation of the battery case 6. When it is detected that the orientation of the battery case 6 is incorrect, the pushing structure will release the elastic potential energy of the spring on the outer wall of the first positioning rod 9, so that the push plate 21 can push the battery case 6 with the incorrect orientation to the upper end of the turning frame 2. Then, the second rotating rod 35 drives the turning structure to move towards the battery case 6 at the upper end of the turning frame 2. Then, the first magnetic attraction block 27 adsorbs and positions the positive electrode block 46. Then, during the process of the turning structure moving towards the limiting plate 55, the second wire winding wheel 33 rotates to drive the connecting rope 30 to traction the second rotating plate 25, so as to correct the battery case 6 with the incorrect orientation. Then, the corrected battery case 6 is conveyed into the pushing-back structure through the turning frame 2. Through the adsorption force of the second magnetic attraction block 39 on the battery case 6, it is judged whether there is a battery case 6 inside each limit frame 3. Then, the spring on the outer wall of the second positioning rod 47 releases the elastic potential energy, so as to push the turned battery case 6 back into the corresponding limit frame 3, solving the problem that a single production line cannot remove the battery cases 6 with incorrect orientations. At the same time, it can also put the corrected battery cases 6 back into the corresponding baffle 4 again, preventing the problem of subsequent production gaps caused by the vacancy in some limit frames 3, and improving the working efficiency of the battery production line.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
