These are conventional technologies and will not be described in detail here.

[0031] The rotating device 5 includes a rotating bracket 51, a rotating motor 52, and a rotating material rack 59. The rotating bracket 51 is mounted on the slide of the lifting device 42, and the rotating motor 52 is mounted on the top of the rotating bracket 51. The rotating material rack 59 is rotatably mounted inside the rotating bracket 51, and the rotating material rack 59 is connected to the rotating motor 52. Specifically, the rotating bracket 51 is equipped with a bearing seat at both ends, and the rotating material rack 59 is equipped with an upper rotating shaft and a lower rotating shaft at both ends. The upper rotating shaft and the lower rotating shaft are both mounted on bearings, and the upper rotating shaft is also connected to the rotating motor 52 via a coupling. The rotating motor 52 drives the rotating material rack 59 to rotate.

[0032] Seven material transfer devices 6 are arranged in a vertical array and include a transfer plate 61, a connecting plate 63, a transfer claw 62, a transfer motor 67, a driving pulley 66, a driven pulley 64, and a transfer belt 65. The transfer plate 61 is mounted on the rotating material frame 59; the transfer claw 62 is L-shaped, with a connecting plate 63 attached to one end. Both ends of the connecting plate 63 are slidably mounted on the rotating material frame 59 via linear guide rails. The transfer claw 62 is horizontally arranged and positioned above the transfer plate 61. Several weight-reducing holes are provided in the transfer claw 62. The material transfer motor 67 is mounted on one end of the rotating material frame 59 and connected to the driving pulley 66. The driven pulley 64 is rotatably mounted on the other end of the rotating material frame 59 and is arranged opposite the driving pulley 66. The material transfer belt 65 is sleeved on the driving pulley 66 and the driven pulley 64. The connecting plate 63 is equipped with a connecting pressure plate 60, which presses the material transfer belt 65 against the connecting plate 63. In order to improve the movement accuracy of the material transfer claw 62, a tensioning device is also included. The tensioning device includes a tensioning pulley 691 and a tensioning seat 692. The tensioning seat 692 is mounted on the rotating material frame 59 and connected to the tensioning pulley 691. The tensioning pulley 691 movably contacts the material transfer belt 65 to tighten the material transfer belt 65.

[0033] In order to determine the position of the material moving claw 62, it also includes an extension position sensor 74, a retraction position sensor 72 and a position detection plate 71. The extension position sensor 74 and the retraction position sensor 72 are respectively installed at both ends of the rotating frame, and are arranged opposite to the position detection plate 71, and are respectively used to detect the extension and retraction of the material moving claw 62; the position detection plate 71 is installed on the connecting plate 63.

[0034] The rotating rack 59 is provided with a material sensor 73, which is arranged opposite to the workpiece and is used to detect whether there is a workpiece. The material sensor 73 is a photoelectric sensor.

[0035] The structure of the feed mechanism 2 is identical to that of the discharge mechanism 3. The feed mechanism 2 comprises a linear feed module 21 and a feed rack 22. The linear feed module 21 is mounted vertically on the buffer rack 13, and the feed rack 22 is mounted on a slide on the linear feed module 21. A plurality of feed pallets 23 for storing workpieces are arranged in an array on the feed rack 22. The feed mechanism 2 and the discharge mechanism 3 are positioned opposite the feed and discharge conveyor lines, respectively. The feed pallets 23 are symmetrically positioned on either side of the feed rack 22, with the spacing between the two feed pallets 23 being greater than the feed conveyor line. This facilitates the raising and lowering of the feed rack 22 at the end of the feed conveyor line, allowing workpieces to be inserted onto the feed pallets 23.

[0036] The discharge device 3 includes a discharge linear module and a discharge rack. Several discharge support plates are symmetrically arranged inside the discharge rack. The distance between two relatively arranged discharge support plates is greater than the discharge conveyor line, which facilitates the lifting and lowering of the discharge rack and further facilitates the workpiece to directly enter the discharge conveyor line.

[0037] The workpiece in this embodiment is a battery pack.

[0038] During storage in stages, the workpiece is transported to the feeding device 2 through the feeding conveyor line, and the feeding linear module 21 drives the feeding rack 22 to rise in sequence, so that the workpiece is inserted into each feeding pallet 23 in sequence, and the number of inserted workpieces is the same as the number of the moving claws 62; a scanner or RIFD recognition can be set on the discharging conveyor line to identify the code of the workpiece, and then the moving device 4 drives the moving device 6 to align with the discharging device 3, and the moving motor 67 drives the moving claw 62 to extend. At this time, the moving claw 62 is above the workpiece, and then the lifting device 42 drives the moving claw 62 to descend and insert the moving claw 62 above the workpiece, and then the moving motor 67 reverses, and the moving claw 62 retracts into the inside of the rotating rack 59, and the workpiece is The material moving claw 62 is pushed onto the material moving plate 61, and then the moving device 4 drives the workpiece and the material moving device 6 to move to the corresponding cache position 11. The cache position 11 is classified according to batch or performance and divided into different material areas. The moving device 4 moves the workpiece to the corresponding material area, and then aligns the workpiece matching the material area with the cache position 11 of the material area. Then the material moving motor 67 is started, and the material moving claw 62 and the material moving plate 61 drive the workpiece to move toward the cache position 11, so that the workpiece enters the cache position 11 and stays on the cache plate 12. Then the lifting device 42 drives the material moving claw 62 to rise above the workpiece, and then the material moving claw 62 retracts, and then the remaining workpieces are inserted into the designated cache positions 11 in turn.

[0039] When feeding in stages, according to the discharge requirements, the moving device 4 drives the material transfer device 6 to move to the corresponding cache position 11. Since the batches or performance of the workpieces in the cache position 11 are similar, seven workpieces can be taken out at a time, and then the seven workpieces are moved to the discharge device 3 as a whole, and the seven workpieces are transported to the discharge position of the discharge device 3 as a whole. Then the discharge device 3 transports the workpieces to the discharge conveyor line in turn, and the discharge conveyor line transports the workpieces to the designated position.
