The drive unit 50 is connected to the position regulating unit 30 in a transmission manner to drive the movement of the position regulating unit 30, thereby opening and closing the support unit 20, making it easier for the workpiece 200 to enter the support unit 20, and preventing the workpiece 200 from unexpectedly leaving the support unit 20.

[0022] 1, 2, and 8, the support unit 20 includes a first support rod 21 and a second support rod 22 spaced apart from each other on the stand 10, and a plurality of partition members 23 attached at intervals between the first support rod 21 and the second support rod 22. In the embodiment of the present application, the workpiece 200 is substantially disk-shaped, and the distance between the first support rod 21 and the second support rod 22 is smaller than the diameter of the workpiece 200. When the workpiece 200 is mounted on the support unit 20, the workpiece 200 is supported by the first support rod 21 and the second support rod 22. One or more workpieces 200 are placed between adjacent partition members 23, which can separate and support the workpieces 200 and reduce the problem of the workpieces 200 accidentally falling due to tilting.

The first position restricting rod 33 is provided at a distance from the first support rod 32, and both ends of the first connecting member 35 are connected to the first position restricting rod 33 and the first support rod 32, respectively. When the first support rod 32 rotates, the first connecting member 35 causes the first position restricting rod 33 to swing, and when the workpiece 200 is mounted on the support unit 20, the range of movement of the workpiece 200 is restricted by the first position restricting rod 33, preventing the workpiece 200 from unexpectedly coming off. One end of the second connecting member 36 is connected to the first support rod 32, and the other end of the second connecting member 36 is rotatably connected to the link 31. The first connecting member 35 and the second connecting member 36 are arranged at an angle, and when the link 31 moves up and down, the first support rod 32 is rotated via the second connecting member 36, thereby causing the first position regulating rod 33 to swing synchronously.

[0026] In the present embodiment, the position regulating unit 30 further includes two other first connecting members 35, the other second connecting member 36, a second support rod 38, a second position regulating rod 39, and a second bracket 37. There are also two second brackets 37, which are fixed to the top of the stand 10, and the second support rods 38 are rotatably connected to the second brackets 37. The second support rods 38 are provided spaced apart from the second position regulating rods 39, and the first connecting member 35 is fixedly connected between the second position regulating rods 39 and the second support rods 38 so that the second position regulating rods 39 swing in accordance with the rotation of the second support rods 38. The second position regulating rods 39 are located approximately on the entrance side of the upper stocker structure in the support unit 20. An interlocking member 312 is further fixed to the link 31, and one end of the other second connecting member 36 is rotatably connected to the interlocking member 312 and the other end is fixedly connected to a second support rod 38. When the link 31 moves up and down, the second support rod 38 is rotated by the interlocking member 312 and the second connecting member 36, and further the second position restricting rod 39 is swung by the first connecting member 35, making it possible to restrict the workpiece 200 at the third support rod 24 and the fourth support rod 25.

The link 31, positioning block 42, transmission rod 41, and drive unit 50 form a rod structure, and when the drive unit 50 abuts against the transmission rod 41 and pushes it, the link 31 can be moved up and down. The workpiece support device 100 further includes an elastic member 43, one end of which is connected to the bottom end of the link 31, and the other end of which is fixedly connected to the stand 10. The elastic member 43 is for returning the link 31.

[0028] A position restriction groove 311 is further formed in the link 31, and a protrusion corresponding to the position restriction groove 311 is provided on the stand 10. When the link 31 moves up and down, the protrusion slides within the position restriction groove 311 relative to the link 31, guiding the movement direction of the link 31 and restricting the movement range of the link 31.

[0029] As shown in FIGS. 5 to 7 , in this embodiment, two first brackets 34 are symmetrically provided on both sides of the stand 10, and a first support rod 32 is rotatably connected between the two first brackets 34.
