[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Currently, the battery cell clamps of overhead cranes maintain the clamping force of the battery cells by continuously working the drive motor or cylinder of the clamp. When there are a large number of clamps, it is impossible to ensure the clamping force of each clamp, which can easily lead to the battery cells falling off.

[0036] Please see Figure 1 To address the aforementioned technical problems, this embodiment provides an overhead crane mechanism for transferring battery cells between two processing stations, including an overhead crane support assembly 10, an overhead crane lateral movement assembly 20, a lateral movement force assembly 30, a gripper lifting assembly 40, a lifting power assembly 50, a gripper material handling assembly 60, and a battery cell anti-drop assembly 70.

[0037] Among them, the overhead crane support assembly 10 serves as a support and guide; the overhead crane lateral movement assembly 20 can move on the overhead crane support assembly 10; the lateral movement force assembly 30 provides driving force for the overhead crane lateral movement assembly 20; the gripper lifting assembly 40 can move vertically and grab the battery cell; and the battery cell anti-drop assembly 70 is used to prevent the battery cell from falling.

[0038] Please see Figure 5 Specifically, the overhead crane support assembly 10 includes a crossbar 11 spanning between two processing stations. The number of crossbars 11 is not limited, but two are preferred. A guide rod 12 is formed along the length of each crossbar 11. The overhead crane traversing assembly 20 has a frame structure, spanning between the two crossbars 11 and slidably mounted on the guide rod 12. The overhead crane traversing assembly 20 can slide back and forth on the guide rod 12, thereby driving the movement of other components mounted on the overhead crane traversing assembly 20.

[0039] Please see Figures 4-5 To drive the movement of the overhead crane traverse assembly 20, the traverse force assembly 30 provided in this embodiment uses a gear and rack mechanism to achieve the movement of the overhead crane traverse assembly 20. The traverse force assembly 30 includes a first drive motor 31 and a first drive shaft 32, both of which are fixed on the overhead crane traverse assembly 20. The first drive shaft 32 is also straddling the two crossbars 11, and the first drive motor 31 drives the first drive shaft 32 to rotate. To achieve the movement of the overhead crane traverse assembly 20, this embodiment also forms a first rack 13 along the length of the crossbar 11, and a first gear 33 that meshes with the first rack 13 is provided at the end of the first drive shaft 32.

[0040] The rotation of the first drive motor 31 drives the first drive shaft 32 to rotate. The first gear 33 meshes with the first rack 13, and the rotation of the first gear 33 causes the entire overhead crane traverse assembly 20 to move along the length of the first rack 13. By controlling the forward and reverse rotation of the first drive motor 31, the direction of movement of the overhead crane traverse assembly 20 can be controlled.

[0041] Please see Figure 3 This is acceptable. Since the entire crane mechanism is powered by the external cable 16, the crane support assembly 10 in this embodiment also includes a guide rail 14 parallel to the crossbar 11. A cable trolley 15 for dragging the cable 16 is slidably suspended on the guide rail 14. The first end of the cable 16 is fixed to a certain point on the guide rail 14 and connected to an external power source; the second end of the cable 16 is fixed to the crane traverse assembly 20 to power the entire crane mechanism; and the middle sections of the cable 16 are fixed at intervals on the cable trolley 15.

[0042] When the overhead crane traverse assembly 20 moves, it drags the cable 16, and the cable trolley 15 moves along the guide rail 14 under the drag of the cable 16. The lengths of the guide rail 14 and the cable 16, as well as the number of cable trolleys 15, can be adjusted according to the distance between two workstations or the moving distance of the overhead crane traverse assembly 20, so as to make it suitable for overhead crane mechanisms in different environments.

[0043] When the overhead crane traverse assembly 20 moves, it will move the cable 16. To prevent the cable 16 from getting caught on other components and causing damage to the overhead crane traverse assembly 20, please refer to [link to relevant documentation]. Figure 2 In this embodiment, a tension detection component 90 is provided at the connection between the cable 16 and the overhead crane traverse assembly 20. The tension detection component 90 includes a position sensor 91 fixedly mounted on the overhead crane traverse assembly 20. The detection end 92 of the position sensor 91 is fixedly connected to the end of the cable 16. When the cable 16 is hung on other components, the cable 16 will be pulled, and the detection end 92 of the position sensor 91 will disengage from the position sensor 91, thereby triggering the position sensor 91. At this time, it is determined that the cable 16 has been pulled.

[0044] Please see Figure 3 To prevent the position sensor 91 from malfunctioning, this embodiment also includes a U-shaped bracket 93. A slider 94 is located in the middle of the U-shaped bracket 93. The slider 94 is mounted to both sides of the U-shaped bracket 93 by springs 95, so that the slider 94 can be held in the middle position by the action of the springs 95 on both sides. The position sensor 91 is fixed on the U-shaped bracket 93, and its detection end 92 is fixed on the slider 94. If the cable 16 is slightly dragged, the position sensor 91 will not be triggered. If the dragging force of the cable 16 is large, the position sensor 91 will be triggered.

[0045] Please see Figure 6 The gripper lifting assembly 40 is vertically movable and positioned on the overhead crane traverse assembly 20. Specifically, the gripper lifting assembly 40 includes a first fixed plate 41 fixed to the overhead crane traverse assembly 20, and a ball screw assembly 42 with one end disposed on the first fixed plate 41 and movable vertically. The ball screw assembly 42 includes a screw 421, a first bevel gear 422 at the top of the screw 421, and a fixed seat 423 movable on the screw 421. The gripper material handling assembly 60 is fixed to the fixed seat 423 of the ball screw assembly 42. Rotation of the screw 421 drives the fixed seat 423 to move up and down, thereby driving the gripper material handling assembly 60 to move up and down.

[0046] Please see Figure 6 In order to drive the movement of the gripper lifting assembly 40, the lifting power assembly 50 provided in this embodiment is fixed on the first fixed plate 41, including a second drive motor 51 and a second drive shaft 52 driven by the second drive motor 51. The two ends of the second drive shaft 52 are provided with second bevel gears 53 that mesh with the first bevel gear 422.

[0047] The rotation of the second drive motor 51 drives the second drive shaft 52 to rotate. The first bevel gear 422 meshes with the second bevel gear 53. The rotation of the first bevel gear 422 causes the screw 421 to rotate, which in turn drives the gripper material-picking assembly 60 on the fixed base 423 to move. By controlling the forward and reverse rotation of the second drive motor 51, the moving direction of the gripper material-picking assembly 60 can be controlled.

[0048] Please see Figure 7 The gripper assembly 60 includes an assembly bracket 61 and a clamping structure 62. The assembly bracket 61 is mounted on the fixed seat 423 of the ball screw assembly 42, and the clamping structure 62 is mounted on the assembly bracket 61. The clamping structure 62 is a press-down unfolding clamping structure. A cylinder 63 is mounted on the assembly bracket 61 to press down the clamping structure 62, causing it to unfold. An elastic component is provided between the clamping structure 62 and the assembly bracket 61, causing the clamping structure to close. The elastic component can be a spring 64.

[0049] Specifically, the assembly bracket 61 includes two parallel mounting plates 611. A cylinder 63 is fixed to the upper mounting plate 611, and a clamping structure 62 is fixed to the lower mounting plate 611. A pressure plate 612 is also provided between the two mounting plates 611, and the pressure plate 612 is pressed down by the cylinder 63. The clamping structure 62 includes a guide post 621, with a linear bearing 622 sleeved on the outside of the guide post 621. The linear bearing 622 is fixed to the lower mounting plate 611. A spring 64 is sleeved on the outside of the guide post 621, with its top abutting against the pressure plate 612 and its bottom abutting against the linear bearing 622. When the cylinder 63 is activated, causing the pressure plate 612 to press down, the pressure plate 612 presses against the guide post 621, causing the guide post 621 to press down. When the cylinder 63 is closed, the guide post 621 is pushed upward by the restoring force of the spring 64.

[0050] To ensure consistent clamping force across the clamping structure 62, this embodiment employs a non-cylinder-based clamping drive structure, avoiding variations in clamping force due to cylinder damage or differing cylinder parameters. The clamping structure 62 used in this embodiment is a press-and-unfold clamping structure; that is, the clamp unfolds when the guide post 621 is pressed down, and closes when the guide post 621 is pushed up. Therefore, the clamping force depends on the rebound force of the spring 64, and the failure rate of the spring 64 is much lower than that of the cylinder 63, thus ensuring a consistent clamping force.

[0051] Multiple clamping structures 62 can be provided on the assembly bracket 61, which can simultaneously clamp multiple battery cells. To further increase the number of battery cells that can be clamped, this embodiment has two sets of gripper assembly 60. The positions of the two sets of gripper assembly 60 are not fixed and the spacing can be adjusted according to the position of the battery cells. Please refer to [link / reference]. Figures 8-9 Specifically, it also includes a gripper material handling assembly adjustment mechanism 80, which includes a second fixed plate 81 fixed to a fixed base 423 of the ball screw assembly 42, and two second racks 82 disposed on the second fixed plate 81 and moving in opposite directions. The assembly bracket 61 of the gripper material handling assembly 60 is slidably disposed on the second fixed plate 81 via a slide rail 84. The assembly brackets 61 of the two sets of gripper material handling assemblies 60 are respectively fixed to the two second racks 82 and driven to move in opposite directions by the second racks 82.

[0052] Two second racks 82 are driven by a gear 83. Since the two second racks 82 are located on both sides of the gear 83, when the gear 83 rotates, the two second racks 82 move in opposite directions, that is, the two second racks 82 move towards each other, which can drive the assembly brackets 61 of the two sets of gripper material picking assemblies 60 to move towards each other, so as to achieve the purpose of adjusting the distance between the gripper material picking assemblies 60.

[0053] Please see Figure 10Alternatively, in this embodiment, a cell anti-drop component 70 is provided below the gripper assembly 60 to prevent the cell from falling. The cell anti-drop component 70 includes two sets of blocks 71 that can move in opposite directions. The two sets of blocks 71 can also move in opposite directions using a rack and pinion mechanism, or they can use a different driving method than the two sets of gripper assemblies 60. In this embodiment, the driving component for the two sets of blocks 71 is a belt drive. Specifically, a mounting block 72 is provided at the bottom end of the screw 421 via a bearing. A transmission belt 73 driven by a motor is provided on the mounting block 72. The end of one set of blocks 71 is fixed to the upper part of the transmission belt 73, and the end of the other block 71 is fixed to the lower part of the transmission belt 73. When the motor drives the transmission belt 73 to rotate, the upper and lower parts of the transmission belt 73 drive to the left and right sides respectively, thereby driving the two sets of blocks 71 to move in opposite directions. When the two sets of stops 71 move toward each other, they close together and are located directly below the clamping structure, forming a blocking mechanism for the battery cell to prevent it from falling and being damaged. When the two sets of stops 71 move away from each other, the stops 71 move beyond the gripper material-picking assembly 60, and a space is formed between the two sets of stops 71 for the gripper material-picking assembly 60 to pick up and drop the battery cell.

[0054] Preferably, a motor-driven transmission belt 73 can be provided at both ends of the stop 71. The stop 71 with this structure can move more smoothly and avoid the two sets of stop 71 tilting and affecting the release effect of the battery cell.

[0055] In this embodiment, two sets of gripper picking components 60 are used, corresponding to two battery cell anti-drop components 70, that is, there are a total of four sets of stops 71. All four sets of stops 71 adopt the above-mentioned driving method. Optionally, the four sets of stops 71 are located at the same end, which can be driven by one motor and one transmission belt 73, and the other end can be driven by another motor and another transmission belt 73.

[0056] A receiving groove 74 matching the shape of the battery cell to be transferred can also be formed on the stop 71.

[0057] In summary, the overhead crane mechanism provided in this embodiment can transfer multiple battery cells and prevent battery cells from falling during the transfer process, thus achieving efficient and safe transfer of battery cells.

[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
