Description

Technical Field

[0002] With the advancement of battery technology, especially the development of cylindrical batteries towards larger size and higher energy density, traditional conveying devices can no longer meet the needs of efficient and precise production. The production of cylindrical batteries mainly relies on automated production lines, and large-scale production is achieved through processes such as winding and packaging.

[0003] However, in the process of battery production, the battery shells are generally poured into the storage compartment, and then the battery shells are put into the production process one by one through the conveyor belt, and then the battery cell components are installed into the battery shell by the robotic arm. However, during the transmission process, some battery shells are not oriented correctly and need to be removed and put back into the production line, or through a dual production line, battery shells with different orientations are processed separately, which greatly increases the production cost, and when the battery shell is removed, there will be a vacancy in that position, affecting the subsequent processing efficiency of the battery.

[0018] 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:

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The positive electrode block is pushed into the cavity of the slide slot through the adjustment plate, so that the detection structure can detect the direction of the battery shell. When it is detected that the direction of the battery shell 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 pushing plate can push the battery shell with incorrect direction to the upper end of the bogie, and then the second rotating rod drives the steering structure to move in the direction of the battery shell at the upper end of the bogie, and then the positive electrode block is adsorbed and positioned by the magnetic block. Then, in the process of the steering structure moving toward the limit plate, the winding wheel second rotates to drive the connecting rope to pull the turning plate second, so that the battery shell with incorrect direction is The battery shell is straightened, and then the straightened battery shell is transferred to the inside of the push-back structure through the bogie. The adsorption force of the magnetic block 2 on the battery shell is used to determine whether there is a battery shell inside each limit frame, and then the elastic potential energy is released by the spring on the outer wall of the positioning rod 2, so as to push the turned battery shell back to the inside of the corresponding limit frame, which solves the problem that a single production line cannot remove battery shells with the wrong direction. At the same time, the corrected battery shell can be put into the inside of the corresponding baffle again to prevent the problem of vacancies in some limit frames causing vacancies in subsequent production, thereby improving the work efficiency of the battery production line.

[0039] 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.

[0040] 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;

[0041] 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;

[0042] A limit seat 22 is installed at one end of the bogie 2 close to the adjustment plate 5. The limit seat 22 is located at the upper end of the bogie 2. The end of the limit seat 22 away from the transmission frame 1 is laterally slidably connected to a movable plate 23. The end of the movable plate 23 away from the limit seat 22 is installed with a steering structure, which can steer the battery shell 6.

[0043] A push-back structure is installed on the side of the bogie 2 away from the limiting seat 22 , which can push the battery shell 6 back into the limiting frame 3 after the steering structure is turned.

[0044] Among them, the pushing structure includes a motor 11, which is fixed to the side of the transmission frame 1 away from the bogie 2. The output end of the motor 11 is fixed with a threaded rod 10, and the outer wall of the threaded rod 10 is screwed with a support seat 7. The side surface of the support seat 7 is slidably connected with a sliding plate 8. The lower end of the sliding plate 8 close to the transmission frame 1 is equipped with a push plate 21, and the push plate 21 can resist the positive electrode block 46. Two steering wheels 13 are installed on the side of the support seat 7 away from the transmission frame 1. The side surface of the lower end of the support seat 7 is rotatably connected with a winding wheel 12, and the winding wheel 12 is fixed to the threaded rod 10. The outer wall of the winding wheel 12 is provided with a traction line 14, and the traction line 14 passes around the two steering wheels 13 and is fixed to the sliding plate 8.

[0045] Specifically, refer to Figure 4 , a positioning rod 9 is installed on the upper end of the sliding plate 8, and a spring is sleeved on the outer wall of the positioning rod 9, and the spring is located between the sliding plate 8 and the support seat 7. When the motor 11 drives the threaded rod 10 and the winding wheel 12 to rotate, the winding wheel 12 will reel the traction line 14, and the pulling direction of the traction line 14 is turned by the two steering wheels 13, so that the sliding plate 8 is pulled away from the transmission frame 1, so that the spring on the outer wall of the positioning rod 9 stores elastic potential energy, and at the same time is restricted by the detection structure, so that the elastic potential energy cannot be released;

[0046] At the same time, the motor 11 can drive the threaded rod 10 to rotate forward and reverse continuously. When rotating forward, the push plate 21 will move a distance synchronously with the limit frame 3. At the same time, the winding wheel 12 will release the traction line 14 on the outer wall, but the sliding plate 8 is restricted and cannot move at this time. When reversing, the push plate 21 will reset, so that it will be synchronized with the next limit frame 3 again. During the resetting process, the winding wheel 12 will rewind the traction line 14, so that the released traction line 14 is wound around the outer wall of the winding wheel 12 again, and so on. During the synchronous movement of the positioning frame 3, if the detection structure detects that the orientation of the battery shell 6 is incorrect, the restriction on the sliding plate 8 will be released, and the spring mounted on the positioning rod 9 will release the elastic potential energy, and the battery shell 6 will be 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 in the opposite direction so that the push plate 21 and the support seat 7 are reset. When the threaded rod 10 rotates in the opposite direction, the winding wheel 12 will also move synchronously, thereby reeling in the traction line 14, so that the sliding plate 8 is pulled back to its original position and is restricted by the detection structure again and cannot move.

[0047] Among them, the detection structure includes a rotating rod 15, which is rotatably connected in the cavity of the slide groove 42. A connecting seat 16 is fixedly connected to the side of the baffle 4 away from the transmission frame 1. A gear 17 is rotatably connected to the outer wall of the connecting seat 16, and the gear 17 is fixed to the rotating rod 15. A gear rod 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 gear rod 18, and the teeth can engage with the gear 17.

[0048] Among them, a slot 20 is opened on the support seat 7 and the side close to the connecting seat 16, and the slot 20 passes through the side surface of the sliding plate 8. The slot 20 and the gear rod 18 can be slidably connected, and a return spring 19 is installed at the lower end of the gear rod 18.

[0049] Specifically, the axis of the rotating rod 15 is the damping shaft. When the reset spring 19 pushes the gear 17 to rotate, the rotating rod 15 will slowly reset when it is reset. When the limit frame 3 carries the battery shell 6 in the wrong direction through the slide 42, the positive block 46 will come into contact with the rotating rod 15 and push the rotating rod 15 to rotate. During the rotation of the rotating rod 15, the gear 17 will be driven to rotate together. During the rotation of the gear 17, the reset spring 19 and the gear rod 18 will be pushed to move away from the slot 20. At this time, if the threaded rod 10 rotates to drive the support seat 7 away from the slot 20, When the connecting seat 16 moves in the direction of movement, the gear rod 18 will disengage from the cavity of the slot 20 on the sliding plate 8, so that the sliding plate 8 will no longer be restricted and unable to move. At this time, during the synchronous movement of the push plate 21 and the limit frame 3, the spring on the outer wall of the positioning rod 9 will push the sliding plate 8 to move in the direction of the bogie 2. At the same time, the push plate 21 also pushes the push plate 21 in the wrong direction toward the position of the bogie 2 until the battery shell 6 is pushed to the upper surface of the bogie 2 and conflicts with the movable plate 23. At the same time, the battery shell 6 can play an auxiliary limiting role during the sliding process of the battery shell 6.

[0050] Among them, the steering structure includes a turn plate 24, which is fixed to the side of the movable plate 23 close to the transmission frame 1, and the end of the turn plate 24 away from the movable plate 23 is rotatably connected to the turn plate 25, and the side of the turn plate 25 close to the limit seat 22 is installed with a clamping seat 26, and the inner wall of the clamping seat 26 is symmetrically slidably connected to two magnetic blocks 27, and the magnetic block 27 can adsorb the outer wall of the positive electrode block 46.

[0051] Among them, the side of the rotating plate 25 away from the clamping seat 26 is fixedly connected to the steering shaft 29, the side of the movable plate 23 away from the rotating plate 1 24 is rotatably connected to the winding wheel 2 33, the outer wall of the winding wheel 2 33 is provided with a connecting rope 30, and the other end of the connecting rope 30 is fixed to the steering shaft 29, one side of the magnetic block 1 27 is fixedly connected to the inclined slider 28, and the inclined slider 28 is slidably connected to the rotating plate 25, and a pushing groove 31 is provided on the side of the rotating plate 1 24 away from the limiting seat 22, and the pushing groove 31 can interfere with the inclined slider 28.

[0052] Among them, the outer wall of the limit seat 22 is fixedly connected to the rotating rod 2 35, the output end of the rotating rod 2 35 is fixedly connected to the movable plate 23, the side of the limit seat 22 close to the movable plate 23 is fixedly connected to the rack 32, the upper end of the winding wheel 2 33 is fixedly connected to the gear 2 34, and the gear 2 34 is meshed with the rack 32.

[0053] Specifically, there is a torsion spring shaft between the rotating plate 1 24 and the rotating plate 2 25, refer to Figure 6When the battery shell 6 moves to the upper end of the bogie 2 and contacts the side surface of the movable plate 23, the rotating rod 2 35 will push the rotating plate 1 24 and the rotating plate 2 25 to move together in the direction of the limit seat 22, and then the clamping seat 26 will come into contact with the positive block 46. At the same time, when the positive block 46 comes into contact with the clamping seat 26, the inclined slider 28 will use its own suction force to magnetically attract the outer wall of the positive block 46. Figure 5 , the rack 32 has teeth only in the direction away from the limit seat 22, and the gear 2 34 will not mesh with the rack 32 when the rotating plate 25 moves in the direction of the limit seat 22. Then, when the rotating rod 2 35 pushes the rotating plate 1 24 and the rotating plate 2 25 to move in the direction away from the limit seat 22 in coordination with the battery shell 6 with the incorrect direction, the gear 2 34 will mesh with the rack 32, causing the gear 2 34 to start rotating. During the rotation of the gear 2 34, the winding wheel 2 33 also rotates together. During the rotation of the winding wheel 2 33, the connecting rope 30 will be driven to pull the magnetic block 2 39. During the pulling of the steering shaft 29, the rotating plate 25 will rotate around the torsion spring axis between the rotating plate 1 24. The rotating plate 25 rotates, and the battery shell 6 with the incorrect direction will also be driven to rotate during the rotation of the rotating plate 25, thereby changing the direction of the battery shell 6. The end of the inclined slider 28 close to the steering shaft 29 extends to the outer surface of the rotating plate 25, and the side of the inclined slider 28 close to the steering shaft 29 is a bevel. When the rotating plate 25 is in contact with the rotating plate 1 24, the bevel of the inclined slider 28 will conflict with the groove wall of the pushing groove 31, thereby pushing the inclined slider 28 to move away from the steering shaft 29. At the same time, the magnetic block 1 27 will also be driven to break away from the adsorption of the positive block 46. At this time, the thrust generated by the bogie 2 on the battery shell 6 will push the battery shell 6 to move in the direction of the push-back structure.

[0054] Among them, the push-back structure includes a connecting plate 36, which is fixed to the side surface of the support seat 7, and the end of the connecting plate 36 away from the support seat 7 is fixed with a bracket 37, the upper end of the bracket 37 is fixed with a positioning ring 40, and the cavity of the positioning ring 40 is slidably connected with a magnetic block 2 39, and the end of the magnetic block 2 39 away from the transmission frame 1 is fixed with a sliding plate 2 41, and the lower end of the sliding plate 2 41 is fixed with a sliding rod 38 close to the transmission frame 1, and the sliding rod 38 is slidably connected to the bracket 37.

[0055] Among them, the upper surface of the bracket 37 away from the end of the sliding plate 2 41 is fixed to the limit plate 55, the side surface of the limit plate 55 is fixed with the positioning rod 2 47, the outer side wall of the positioning rod 2 47 is slidably connected with the reset ring 45, the side of the bogie 2 away from the transmission frame 1 is fixed with the rotating shaft rod 44, and the outer side wall of the rotating shaft rod 44 is symmetrically installed with two connecting rods 43, the lower connecting rod 43 is rotatably connected to the sliding rod 38, and the upper connecting rod 43 is rotatably connected to the side of the reset ring 45 with the magnetic block 3 50, and the magnetic block 3 50 is slidably connected to the limit plate 55, and a spring is installed between the limit plate 55 and the reset ring 45.

[0056] Among them, a sliding groove 51 is provided on the side surface of the reset ring 45, and the inner side wall of the sliding groove 51 is slidably connected to the contact rod 48. The side of the reset ring 45 close to the magnetic block 3 50 is slidably connected to the conical magnetic block 49, and the conical magnetic block 49 can interfere with the interference rod 48. A spring is fixed between the conical magnetic block 49 and the reset ring 45. An electric slide rail 52 is provided on the upper surface of the limit plate 55. An oblique push block 53 is slidably connected in the cavity of the electric slide rail 52, and the oblique push block 53 can interfere with the interference rod 48. One side of the oblique push block 53 is a bevel. When the bevel of the oblique push block 53 contacts the interference rod 48, it will push the interference rod 48 to slide upward.

[0057] Specifically, the bracket 37 is fixedly connected to the support base 7 via the connecting plate 36, so that when the support base 7 moves, the bracket 37 and the limiting plate 55 also move synchronously, so that when the push-back structure pushes the turned battery shell 6 back into the original limiting frame 3, the battery shell 6 will not flip over due to the different movement speeds of the push-back structure and the limiting frame 3;

[0058] For each limit frame 3 passing through the position of the positioning ring 40, if there is a battery shell 6 inside the limit frame 3, the magnetic block 2 39 may be adsorbed and moved toward the direction of the transmission frame 1. During the movement of the magnetic block 2 39, the sliding plate 2 41 will drive the sliding rod 38 to slide together in the direction of the transmission frame 1. 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 rod 43, the magnetic block 3 50 will be pushed to move in the direction of the conical magnetic block 49, so that the conical magnetic block 49 is pulled by the magnetic force. When there is no battery shell 6 inside the limit frame 3, the magnetic block 2 39 will be reset. Figure 7 A spring for resetting is installed between the sliding plate 2 41 and the positioning ring 40. Then, when the magnetic block 2 39 is reset, the sliding rod 38 will also be reset. At this time, the magnetic block 3 50 will be away from the conical magnetic block 49. When the reset ring 45 is close to the side of the transmission frame 1 where the battery shell 6 is rotated, the conical magnetic block 49 will be attracted and move in the direction of the rotated battery shell 6. Figure 10The oblique side of the conical magnetic block 49 conflicts with the resistance rod 48. At this time, the conical magnetic block 49 will push the resistance rod 48 to slide upward. The resistance rod 48 sliding upward will cause the resistance rod 48 to disengage from the oblique push block 53. At this time, the spring on the outer wall of the positioning rod 2 47 will release the elastic potential energy, thereby pushing the rotated battery shell 6 to reinsert into the interior of the limit frame 3 at the corresponding position. At the same time, the magnetic block 2 39 will magnetically position the battery shell 6 inserted back into the limit frame 3 again to prevent the battery shell 6 from deflecting, thereby improving the stability of the device.

[0059] A conveying method for a conveying device for producing cylindrical batteries, comprising the following steps:

[0060] S1. First, the battery shell 6 is transferred on the transfer rack 1 and is regulated by the adjustment plate 5 and the baffle 4. Then, when the positive electrode block 46 is not oriented correctly, it will conflict with the rotating rod 15, so that the detection device can determine whether the orientation of the battery shell 6 is correct.

[0061] S2. Then the push plate 21 will move a certain distance along with the battery shell 6 with the incorrect direction. During the movement, the gear rod 18 is no longer inserted into the inside of the slot 20, so that the sliding plate 8 is released from the restriction, so that the sliding plate 8 drives the push plate 21 to push the battery shell 6 with the incorrect direction to the upper end of the bogie 2.

[0062] S3. When the battery shell 6 with an incorrect direction is pushed to the upper end of the bogie 2, the clamping seat 26 will partially cover the positive block 46, and at the same time the magnetic block 1 27 will adsorb the positive block 46, and then the winding wheel 2 33 will rotate to pull the rotating plate 25 to rotate. During the rotation of the rotating plate 25, the battery shell 6 with an incorrect direction will be turned over, so that the direction of the battery shell 6 is turned to the correct direction.

[0063] S4. Finally, after the battery shell 6 is flipped in the incorrect direction, as the bogie 2 pushes, the battery shell 6 will conflict with the inner wall of the limit plate 55, and then the battery shell 6 will be pushed back to the inside of the limit frame 3 where the battery shell 6 was originally taken out through the push-back structure.

[0064] Working principle: The battery shells 6 are transported in sequence through the limit frame 3 on the transmission rack 1. During the transportation process, each battery shell 6 is regularized by the cooperation of the adjustment plate 5 and the baffle 4. When the battery shell 6 is in the wrong direction, the positive block 46 will enter the cavity of the slide groove 42, so that the detection structure can detect the direction of the battery shell 6. When it is detected that the direction of the battery shell 6 is incorrect, the pushing structure will release the elastic potential energy of the spring on the outer wall of the positioning rod 1 9, so that the push plate 21 can push the battery shell 6 with incorrect direction to the upper end of the bogie 2, and then the rotating rod 2 35 drives the steering structure to move in the direction of the battery shell 6 at the upper end of the bogie 2, and then the positive block 46 is adsorbed and positioned by the magnetic block 27, and then in the process of the steering structure moving toward the limit plate 55, the positive block 46 is adsorbed and positioned. The rotation of the winding wheel 2 33 drives the connecting rope 30 to pull the turn plate 2 25, so that the battery shell 6 with incorrect direction is straightened, and then the straightened battery shell 6 is transmitted to the inside of the push-back structure through the bogie 2, and the adsorption force of the magnetic block 2 39 on the battery shell 6 is used to determine whether there is a battery shell 6 inside each limit frame 3, and then the elastic potential energy is released by the spring on the outer wall of the positioning rod 2 47, so as to push the turned battery shell 6 back to the inside of the corresponding limit frame 3, which solves the problem that a single production line cannot remove the battery shell 6 with the wrong direction, and at the same time, the corrected battery shell 6 can be put into the inside of the corresponding baffle 4 again, to prevent the problem of vacancies in some limit frames 3 and cause vacancies in subsequent production, thereby improving the work efficiency of the battery production line.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
