[0026] The following will be combined with the attached Figure 1 -Attached Figure 4 The present invention is further illustrated by the following embodiments.

[0027] This embodiment discloses an automatic battery cell feeding device for a PACK production line.

[0028] Reference Figures 1 to 4 The automatic cell loading device of the PACK production line includes a manipulator 1 and a tray 2. The tray 2 is provided with a plurality of troughs 21, into which cells are respectively transferred. The tray 2 and the cells are transported to the side of the manipulator 1 by means of transportation in the production workshop. The manipulator 1 is used to sequentially grab the cells in the tray 2 to the next process to realize automatic loading. One end of the manipulator 1 for grabbing the cells is a grabbing end 11. In this embodiment, the grabbing end 11 of the manipulator 1 is provided with a suction nozzle 12, and the manipulator 1 grabs the cells by vacuum adsorption.

[0029] The battery cell is generally rectangular, and the material trough 21 of the material tray 2 is opened as a rectangular trough corresponding to the shape of the battery cell. Two opposite inner walls of the material trough 21 are respectively provided with clamps 3, and the two clamps 3 are used to clamp the battery cell placed in the material trough 21. The side of the clamp 3 used to clamp the battery cell is roughened to improve the stability of the clamp 3 clamping the battery cell. Specifically, the end of the clamp 3 facing the battery cell is the outer end, and the end of the clamp 3 facing away from the battery cell is the inner end. A telescopic hole is opened on the side of the material trough 21 facing the inner end of the clamp 3, and a telescopic rod 31 is movably arranged in the telescopic hole, and the clamp 3 is fixedly connected to the outer end of the telescopic rod 31. A clamping hole 41 is opened vertically through the inner end of the telescopic rod 31, and a locking hole 42 is opened vertically at the bottom of the telescopic hole. The locking hole 42 has the same diameter as the clamping hole. In the process of the telescopic rod 31 extending outward, the clamping hole 41 can be aligned with the locking hole 42. Furthermore, a locking rod 43 is vertically movably arranged in the locking hole 42, and a locking spring 44 is connected between the bottom of the locking rod 43 and the bottom of the locking hole 42. When the clamping hole 41 is aligned with the locking hole 42, the locking rod 43 is rebounded into the clamping hole 41 under the action of the locking spring 44, so that the locking rod 43 is clamped with the telescopic rod 31, so that the two clamps 3 can stably clamp the battery cells in the material trough 21, ensuring the stability of the battery cells when they are transported using the material tray 2.

[0030] A return spring 52 is connected between the telescopic rod 31 and the material tray 2. The return spring 52 makes the telescopic rod 31 have a tendency to retract, so that the two clamping plates 3 have a tendency to move away from each other. A release hole 51 is opened at the top of the telescopic hole. The release hole 51 penetrates the top surface of the material tray 2 upward. The release hole 51 is vertically aligned with the lock hole 42, and the diameter of the release hole 51 is smaller than the diameter of the lock hole 42. The gripping end 11 of the manipulator 1 is provided with a release rod 13, which is used to be inserted into the release hole 51 and press down the lock rod 43, the lowest point of the release rod 13 is lower than the lowest point of the suction nozzle 12, and the height difference between the lowest point of the release rod 13 and the lowest point of the suction nozzle 12 needs to be such that when the manipulator 1 grabs the battery cell, the release rod 13 is first inserted into the release hole 51 and the lock rod 43 is completely pressed back into the lock hole 42, and then the suction nozzle 12 is in place to suck the material, so that when the manipulator 1 grabs the battery cell, the two clamps 3 move away from each other under the elastic force of the reset spring 52, so that the battery cell is no longer clamped, avoiding obstruction to the process of the manipulator 1 grabbing the battery cell. In summary, the automatic battery cell loading device of the PACK production line of the present invention can not only ensure the stability of the battery cell when it is transported using the material tray 2, but also avoid obstruction to the process of the manipulator 1 grabbing the battery cell.

[0031] An adjustment slot 53 is provided between the top and bottom of the telescopic hole, and an adjustment plate 54 is fixedly connected to the top and bottom of the telescopic rod 31, respectively. The two adjustment plates 54 of the telescopic rod 31 are respectively slidably arranged in the two adjustment slots 53, and the two adjustment plates 54 of the telescopic rod 31 are respectively connected to the inner walls of the two adjustment slots 53 with the above-mentioned reset spring 52, so as to realize the reset control of the telescopic rod 31 by the reset spring 52. Furthermore, a trumpet-shaped opening with a larger top and a smaller bottom is provided at the top of the release hole 51, so that the release rod 13 of the material grabbing end 11 of the manipulator 1 can be inserted into the release hole 51.

[0032] A lifting block 6 is movably provided at the bottom of the material trough 21, and the lifting block 6 moves in the vertical direction. A linkage structure is connected between the lifting block 6 and the two clamps 3. The lifting block 6 extends upward as the two clamps 3 move relatively away from each other, and the two clamps 3 move relatively close to each other as the lifting block 6 descends. The effect is: on the one hand, when the two clamps 3 release the battery cells, the lifting block 6 simultaneously lifts up the battery cells, shortening the descending stroke of the grabbing end 11 of the manipulator 1; on the other hand, when the material tray 2 is loaded again, the battery cells loaded into the material trough 21 can make the lifting block 6 retract downward, and the lifting block 6 drives the two clamps 3 to be relatively close, so that the locking rod 43 locks the telescopic rod 31 of the clamp 3 again, and finally the two clamps 3 clamp the battery cells placed in the material trough 21 again for subsequent transportation.

[0033] Specifically, the linkage structure includes a first gear 71, a second gear 72, a rack 73 and a connecting rod 74. The left and right sides of the lower end of the lifting block 6 are provided with tooth surfaces. Two first gears 71 are provided. The two first gears 71 are rotatably arranged on the left and right sides of the lifting block 6. The two first gears 71 respectively mesh with the two tooth surfaces of the lifting block 6. Two second gears 72 are provided. The two second gears 72 are also rotatably arranged on the left and right sides of the lifting block 6. The two second gears 72 are respectively meshed with the two first gears 71. Two racks 73 are provided. The two racks 73 are respectively slidably arranged on the left and right sides of the lifting block 6. The two racks 73 slide in the horizontal direction, and the two racks 73 are respectively meshed with the two second gears 72. Two connecting rods 74 are provided. The connecting rods 74 are L-shaped. The two connecting rods 74 are connected between the two racks 73 and the two clamping plates 3 in a one-to-one correspondence. Through the above arrangement, when the two clamps 3 release the battery cell, the two clamps 3 synchronously drive the two racks 73 away from each other, and the toothed belt drives the second gear 72 meshing with it to rotate clockwise, and the second gear 72 drives the first gear 71 meshing with it to rotate counterclockwise, and the first gear 71 finally drives the lifting block 6 meshing with it to extend upward and lift the battery cell; when the battery cell is put into the trough 21 again, similarly, the first gear 71 and the second gear 72 rotate in the opposite direction, so that the two racks 73 approach each other, so that the two clamps 3 approach each other, and finally the two clamps 3 clamp the battery cell again. In addition, the diameter of the first gear 71 is smaller than the diameter of the second gear 72, so that it is more labor-saving when the battery cell is loaded into the trough 21 of the tray 2 again. It should be noted that the tray 2 needs to have a space for the first gear 71 and the second gear 72 to rotate, and a space for the connecting rod 74 to slide.

[0034] In order to facilitate the loading of parts such as the first gear 71, the second gear 72, etc. into the material tray 2, in some embodiments, the material tray 2 is designed as a split structure, and the joints of the splits pass through the material trough 21, so that the material tray 2 can be spliced ​​and assembled after the parts are assembled, thereby achieving the effect of facilitating the production of the material tray 2.

[0035] The above are all preferred embodiments of the present invention, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
