Description

Technical Field

[0002] With the increasing maturity of new energy technologies, prismatic battery cells have been widely used in new energy vehicles and other products, resulting in huge market demand. New energy production processes often employ automated equipment. Existing production lines commonly use gripper-turning mechanisms to flip and transfer battery cells. A single turning mechanism integrates multiple actions such as rotation, flipping, and transfer, leading to long cycle times. To keep pace with other equipment, it is often necessary to add more turning mechanisms or improve the efficiency of each action within the turning mechanism. However, adding multiple turning mechanisms on a single production line makes coordination difficult, posing significant challenges to the line layout. Increasing the cycle time often results in mechanism malfunctions or inaccurate movements. Therefore, designing an efficient and stable turning device is essential.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

Detailed Implementation

[0026] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0027] In the battery cell coating system, the flipping and feeding device 100 is located downstream of the large-scale coating device, which is used to coat the two large surfaces and the bottom surface of the battery cell that has not been wrapped with insulating film. The battery cell coated by the large-scale coating device is fed into the conveying device 10, where it is conveyed in a horizontal position.

[0028] See Figures 1 to 5 In one embodiment, the flipping and loading device 100 is used to change the orientation of the battery cells during the loading process. The flipping and loading device 100 includes a conveying device 10, a flipping device 20, and a loading device 30. The conveying device 10 can be a structure connected to upstream equipment, for example, the conveying device 10 can be connected to the output end of a large bread-shaped device, and the conveying device 10 can carry and convey battery cells in a horizontal orientation. The flipping device 20 is located downstream of the conveying device 10 and is used to load battery cells from the conveying device 10. The loading device 30 is located downstream of the flipping device 20 and is used to transfer the flipped battery cells.

[0029] See Figure 2In this embodiment, the conveying device 10 includes a support 11 and a conveyor belt 12. The conveyor belt 12 is mounted on the support 11, and the battery cells are transported on the conveyor belt 12. A cavity 15 is provided at the connection between the conveyor belt 12 and the anti-collision device. The flipping component 23 of the flipping device 20 can extend into the cavity 15, and the flipping component 23 can load the battery cells at the location of the cavity 15. A baffle 16 is laid above the conveyor belt 12 to prevent the battery cells from falling off the conveyor belt 12. The support 11 is also provided with a first positioning component 13, a guardrail, and a second positioning component 14. The first positioning component 13 is located at the input end of the conveyor belt 12 and includes a pair of cylinder positioning blocks 131. The cylinder positioning blocks 131 are respectively located on both sides of the conveyor belt 12 and can clamp and fix the battery cells from both sides, which can be used to control the input frequency of the battery cells. The second positioning component 14 is located at the output end of the conveyor belt 12. The second positioning component 14 includes a pair of cylinder clamping blocks 141, which are respectively located on both sides of the conveyor belt. These cylinder clamping blocks 141 can clamp and fix the battery cells from both sides, and can avoid the insulating film clamping the sides of the battery cells. The second positioning component 14 can clamp and fix the battery cells for stable loading by the flipping device 20. In the middle of the conveyor belt 12, guardrails are installed on both sides. Sensors can be installed on the guardrails to detect whether adjacent battery cells are colliding.

[0030] See Figures 3 to 5 In this embodiment, the flipping device 20 includes a base 21, a rotating assembly 22, and a flipping assembly 23. The base 21 includes a bottom plate 211 and multiple mounting plates 212, which are respectively fixed to the bottom plate 211 and located on both sides of the bottom plate 211. The rotating assembly 22 is mounted on the mounting plates 212, and the flipping assembly 23 is mounted on the rotating assembly 22. The rotating assembly 22 rotates around a first axis, and the multiple flipping assemblies 23 are spaced apart circumferentially along the rotating assembly 22. The direction of the first axis can be perpendicular to the conveying direction of the conveying device 10. The battery cells move to the end of the conveyor belt 12 and are sequentially loaded into the flipping device 20 within the cavity 15. The loading action is very smooth, without any unnecessary transitional movements.

[0031] Preferably, the multiple flipping components 23 can be arranged at equal angular intervals. The interval angle between adjacent flipping components 23 refers to the angle between the central symmetry plane of one flipping component 23 and the central symmetry plane of the adjacent flipping component 23. The interval angle between adjacent flipping components 23 is the same as the angle of rotation required to change the posture of the battery cell. For example, if it is necessary to flip a battery cell from a horizontal position to a vertical position, the battery cell needs to be flipped by 90°. Four sets of flipping components 23 can be evenly spaced on the rotating component 22. One battery cell can be flipped every 90°, and continuous flipping can be achieved.

[0032] In this embodiment, the rotating assembly 22 includes a first drive 221 and a rotating body 24. The rotating body 24 is connected to the first drive 221. Preferably, four sets of flipping components 23 can be evenly spaced on the surface of the rotating body 24, and the rotating body 24 can flip a horizontal battery cell into a vertical battery cell every 90° rotation.

[0033] The first drive 221 includes a motor 2212, a rotary cylinder 2211, a reducer 222, and a coupling 223. The mounting plate 212 has corresponding mounting holes, which can accommodate bearings. These holes allow the output ends of the rotating shaft 224 and the reducer 222 to pass through and connect to other components. The bearings reduce rotational friction on the rotating shaft 224 and its output end. The motor and rotary cylinder are connected to both ends of the rotating body 24, respectively. The combined use of the motor 2212 and the rotary cylinder 2211 balances both rotational speed and accuracy requirements. One end of the rotating body 24 has a rotating shaft 224 connected to the motor. The rotary cylinder 2211 is connected to the end face of the rotating body 24 via a flange. Preferably, the reducer 222 is connected to the output end of the motor 2212, and the output end of the reducer 222 passes through the mounting plate 212. The motor 2212 and the reducer 222 are fixed together on the mounting plate 212. The output end of the reducer 222 is connected to one end of the rotating shaft 224 via a coupling 223.

[0034] In this embodiment, the flipping assembly 23 includes a mounting base 231, a flipping gripper 232, and side stops 233. The mounting base 231 is mounted on the surface of the rotating body 24, and the flipping gripper 232 is assembled on the mounting base 231. The flipping gripper 232 can be driven to open and close by a cylinder or a motor. The flipping gripper 232 opens and closes radially perpendicular to the first axis to clamp the large surface of the horizontally positioned battery cell. Side stops 233 are provided on both sides of the flipping gripper 232. The side stops 233 protrude a small portion from the inner bottom surface of the flipping gripper 232. The battery cell is placed on the stops 233, and the side stops 233 on both sides provide support for the battery cell.

[0035] See Figure 1 and Figure 5 In this embodiment, the feeding device 30 includes a base 34, a rotating assembly 32, and feeding assemblies 33. The rotating assembly 32 is mounted on the base 34 and rotates about a second axis, which is perpendicular to the first axis and is in a vertical direction. A plurality of feeding assemblies 33 are mounted on the rotating assembly 32.

[0036] In this embodiment, the rotating assembly 32 includes a second drive 31 and a rotating bracket 11. The second drive 31 can be a rotary motor. The second drive 31 is connected to the rotating bracket 11, which has multiple fixing parts 321 arranged symmetrically about a second axis. Each fixing part 321 is provided with a feeding assembly 33. The rotating bracket 11 adopts a centrally symmetrical structure, which allows the rotating assembly 32 to be more stable during the transfer process. When one feeding assembly 33 performs a clamping action, the other feeding assembly 33 can simultaneously perform a placing action. The operations of the two feeding assemblies 33 do not interfere with each other, greatly improving the transfer efficiency. Preferably, the rotating bracket 11 also includes a rotating part 323 and a connecting part 322. The rotating part 323 is sleeved on the second drive 31. One end of the connecting part 322 is fixed to the rotating part 323, and the other end is connected to the fixing part 321. The connecting part 322 includes several hollow connecting plates 3221.

[0037] In this embodiment, the feeding assembly 33 includes a lifting assembly and a clamping assembly. The lifting assembly is mounted on the fixing part 321, and the clamping assembly is disposed on the lifting assembly and can move up and down along the second axis with the lifting assembly. Preferably, the lifting assembly includes a vertical plate 331, a third drive 332, and a lifting seat 333. The vertical plate 331 is fixed on the fixing part 321, and the clamping assembly is mounted on the bottom of the lifting seat 333. One end of the third drive 332 is connected to the vertical plate 331, and the other end is connected to the lifting seat 333. The third drive 332 may be a motor. The clamping assembly includes a pair of feeding jaws 334. The opening and closing direction of the feeding jaws 334 is perpendicular to the radial direction of the second axis. At the same time, the opening and closing direction of the feeding jaws 334 pre-clamped on the flipping device 20 is also perpendicular to the opening and closing direction of the flipping jaws 232, so as to extend into the coating of the battery cell from above and clamp the side of the battery cell. Preferably, the width of the feeding claw 334 is smaller than the width of the side of the battery cell, so that the feeding claw 334 can avoid the blue film and avoid clamping the blue film on the battery cell.

[0038] In one embodiment, the battery cell coating system includes the aforementioned flipping and feeding device 100 and coating device. The flipping and feeding device 100 is located downstream of the coating device. The coating device is used to coat the battery cell on its two large surfaces and to transport the coated battery cell to the flipping and feeding device 100 to prepare for subsequent processes such as coating the sides and top.
