In addition, the lifting member 110 may be provided with a plurality of lifting structures, and each lifting structure is connected to the corresponding lifting rod 120 to drive the corresponding lifting rod 120 to lift.

Each bearing member 130 has a pivot end and a bearing end which are oppositely arranged, the pivot end of each bearing member 130 is pivoted with the corresponding lifting rod 120 and can only rotate upwards, and the bearing end of each bearing member 130 exceeds the inner side of the corresponding lifting rod 120, so that the bearing ends of the plurality of bearing members 130 can bear workpieces together.

Specifically, each bearing member 130 is pivotally connected to the upper end of the corresponding lifting rod 120, so that each bearing member 130 is convenient to install. In addition, a groove structure may be disposed inside each of the lifting rods 120, and each of the supporting members 130 is pivotally connected to the corresponding groove structure.

The number of the lifting rods 120 is the same as that of the bearing members 130 and is at least three. Preferably, the number of the lifting rods 120 is four, and the connecting lines of the four lifting rods 120 are arranged in a rectangular shape. So set up, can bear the weight of four extreme angle departments of work piece, and then make piling up of work piece deposit stably. In addition, the number of the lifting rods 120 may be set to three, five, or other values.

With the above technical solution, when the workpiece storage apparatus 100 stores the first workpiece, first, the lifting member 110 drives the plurality of lifting rods 120 and the plurality of carriers 130 to descend together until the plurality of carriers 130 are all lower than the first workpiece. Next, the first workpiece is conveyed above the plurality of carriers 130 by a workpiece conveying device 300 which will be described later. Then, the lifting member 110 drives the plurality of lifting rods 120 and the plurality of carriers 130 to ascend together until the plurality of carriers 130 carry the first workpiece, and the workpiece transporting device 300 releases the first workpiece, so that the storage of the first workpiece can be completed.

Next, the second workpiece is conveyed below the first workpiece by the workpiece conveying device 300. Then, the lifting member 110 drives the lifting rods 120, the supporting members 130 and the first workpiece to descend together until the supporting members 130 are blocked by the edge of the second workpiece and rotate upwards to abut against the side edge of the second workpiece, so that the first workpiece is stacked on the second workpiece. Then, the lifting member 110 continues to drive the plurality of lifting rods 120 and the plurality of bearing members 130 to descend together until each bearing member 130 descends to be located below the second workpiece, and each bearing member 130 is not affected by the second workpiece and rotates under the self gravity to return to the initial state.

Two elevating platforms 610 set up along vertical parallel interval, and each elevating platform 610 all follows vertical sliding connection in board 200, and the surface that two elevating platforms 610 are close to each other is located to a plurality of plummer 620 branch to make a plurality of plummers 620 and two elevating platforms 610 construct and form a plurality of layers of depositing of arranging along vertical interval, each layer of depositing all is used for depositing the work piece of packing into the work piece. The driving mechanism 630 is disposed on the machine platform 200 and is used for driving the two lifting platforms 610 to synchronously lift.

Each storage layer on the workpiece storage device 600 supports two sides of the workpiece which are oppositely arranged in the longitudinal direction, and then clamps or releases the workpiece along the transverse direction by matching with the clamping mechanism 320. The arrangement is such that the storage of the workpiece and the clamping by the clamping mechanism 320 do not interfere with each other.

With the above-described configuration, when the workpiece conveying device 300 conveys the workpiece from the workpiece stocker 600 to the work station 200a, first, the traverse mechanism 310 drives the gripping mechanism 320 to move in the lateral direction to the lower side of the workpieces in multiple stages. Next, the drive mechanism 630 drives the multiple tiers of workpieces downward until the lowermost workpiece is lowered into the gripper mechanism 320. Then, the gripping mechanism 320 grips the workpiece in the lateral direction, and the lateral movement mechanism 310 drives the gripping mechanism 320 to move to the work station 200a together with the workpiece. Finally, after the work is performed, the traverse mechanism 310 drives the gripping mechanism 320 to transfer the work to the work stocker 100 for storage. This is repeated to store all the workpieces in the workpiece stocker 600 after the completion of the relevant work.

In other embodiments, the workpiece stocker 600 may be configured as a cabinet-type hierarchical storage structure, a carousel-type storage structure, or the like.

The driving mechanism 630 is configured according to the specific type of the lifting member 110 in the above embodiments, and is not described in detail herein.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
