[0024] Various embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. In each of the drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, the various parts in the drawings are not drawn to scale.

[0025] The present utility model provides a rotating tray rack. Refer to Figures 1 to 4 , the rotating tray rack includes a cabinet body 1, a tray rack 2 and a driving mechanism; wherein, the cabinet body 1 is a box structure with a hollow interior, and an opening is provided on the front side of the cabinet body 1; the tray rack 2 includes a central rack 21 and a plurality of support racks arranged circumferentially on the central rack 21, and each group of the support racks includes a plurality of support rack units arranged at intervals in the height direction of the central rack 21, and the support rack units are used for placing trays 6; the upper and lower ends of the tray rack 2 are respectively rotatably connected to the top plate and the bottom plate of the cabinet body 1, and the driving mechanism is arranged on the cabinet body 1, and the output end of the driving mechanism is in transmission connection with one end of the tray rack 2 to drive the tray rack 2 to rotate horizontally.

[0026] Specifically, the cross-section of the cabinet body 1 is square, the center of the tray rack 2 is located at the center of the cross-section of the cabinet body 1, and the cabinet body 1 is formed by welding profiles to form a frame structure, and a steel plate is installed outside to form a hollow box structure for accommodating the tray rack 2 inside. The driving mechanism can drive the tray rack 2 to rotate, and rotate one group of support racks to a position facing the opening of the cabinet body 1, so as to facilitate the robot arranged directly opposite the opening of the cabinet body 1 to pick up and place the trays 6 on the plurality of support rack units of the support rack. Compared with the existing tray rack design, the rotating tray rack of the present application changes the tray rack from a planar single-layer structure to a three-dimensional rotating structure. Under the same floor area, the storage quantity of the trays 6 is increased, and at the same time, the pick-up and placement quantity of the trays 6 within the moving range of the industrial robot is increased.

[0027] Further, a switchable cabinet door 11 is provided at the rear side of the cabinet body 1. The number of the support frames is an even number group, and the even number group of the support frames are evenly distributed in the circumferential direction. With such a setting, when the driving mechanism drives the tray rack 2 to rotate so that one group of the support frames faces the opening at the front side of the cabinet door 11, another group of the support frames symmetrically arranged with this group of the support frames faces the switchable cabinet door 11 at the rear side of the cabinet door 11. The staff can open the cabinet door 11 to manually pick up and place the tray 6, which is separated from the operation area of the robot. While improving the picking and placing efficiency of the tray 2, the safety of personnel operation is ensured. In this embodiment, the tray rack 2 is provided with four groups of support frames, and the four groups of support frames are evenly distributed in the circumferential direction, that is, every time the tray rack 2 rotates 90°, one group of support frames faces the opening at the front side of the cabinet body 1.

[0028] Further, the support frame unit includes two spaced and oppositely arranged support plates 22. The two support plates 22 are respectively used to support both sides of the bottom surface of the tray 6, so as to realize the support of the tray 6. Such a design can also reduce material consumption and reduce the overall weight of the tray rack 2. At the same time, the gap between the two support plates 22 also facilitates the manipulator of the industrial robot to grab the middle part of the tray 6, which is convenient for picking up and placing the tray 6. The support frame further includes two vertically and spaced support frames 23, and the two support frames 23 are fixedly arranged on the central frame 21. The two support plates 22 of each support frame unit are respectively fixedly arranged on the two support frames 23. In this embodiment, the central frame 21 and the support frames 23 are both welded by square tubes, and the central frame 21 and the support frames 23 are welded into one body, so that the tray rack 2 has a centrally symmetric frame structure; the support plate 22 has an L-shaped structure, the short side of the support plate 22 is welded and fixed on the support frame 23, and the long side of the support plate 22 is horizontally arranged to support the tray 6.

[0029] Furthermore, in order to facilitate the rotational connection of the upper and lower ends of the tray rack 2 to the cabinet body 1, a flange 24 is fixedly provided at each of the upper and lower ends of the tray rack 2, and a boss shaft 25 is fixedly provided on each of the flanges 24. The upper and lower ends of the tray rack 2 are respectively rotationally connected to the top plate and the bottom plate of the cabinet body 1 through the boss shafts 25. Specifically, the flange 24 is made of a steel plate with a certain thickness to ensure sufficient support strength. The flange 24 is fixedly connected to the upper and lower ends of the tray rack 2 by welding or bolt connection. The boss shaft 25 is fixedly connected to the flange 24 by welding or bolt connection. The center of the flange 24, the center of the tray rack 2, and the axis of the boss shaft 25 coincide. In this embodiment, a connecting flange is provided at one end of the boss shaft 25 connecting the flange 24, and a plurality of bolt holes are circumferentially and evenly provided on the connecting flange. Corresponding threaded holes are provided on the flange 24, and the boss shaft 25 is fixedly connected to the flange 24 through a plurality of bolts. The boss shaft 25 is connected to the flange 24 by bolt connection, which can avoid the influence of welding deformation caused by welding connection on the coaxiality of the upper and lower two boss shafts 25.

[0030] Furthermore, rolling bearings are provided between the boss shaft 25 at the upper end of the tray rack 2 and the top plate of the cabinet body 1, and between the boss shaft 25 at the lower end of the tray rack 2 and the bottom plate of the cabinet body 1. By providing rolling bearings between the boss shaft 25 and the cabinet body 1, the frictional resistance during the rotation of the tray rack 2 can be reduced, and the flexibility of the tray rack 2 during rotation on the cabinet body 1 can be improved. As a preference, the rolling bearing provided between the boss shaft 25 at the lower end of the tray rack 2 and the bottom plate of the cabinet body 1 is a tapered roller bearing, which can bear both the radial load during the rotation of the tray rack 2 and the axial load generated by the weight of the tray rack 2, thereby ensuring the stability of the tray rack 2 during rotation.

[0031] Further, the driving mechanism is a servo motor 3, and the output shaft of the servo motor 3 is connected to the boss shaft 25 at the upper end of the tray rack 2 through a coupling 4.
