[0031] In the specific implementation of this application, multiple industrial robots are arranged on a workbench at intervals, and the industrial robots are equipped with actuators. For example, as shown in the figure, there are 3 or 4 industrial robots; the actuator is a spraying mechanism, such as a spray gun; the workbench is located at the rotation center of the rotating frame mechanism, and when the driving mechanism drives the rotating frame mechanism to rotate, the material rotation mechanism 2 is rotated from the back of the industrial robot to the front of the industrial robot. Secondly, when spraying, the material rotation mechanism 2 fixes the material through the material opening mechanism, and then drives the material opening mechanism and the material to rotate through the rotating mechanism, so that the actuator can work on the material and perform operations within 360 degrees. When loading, since the carrier bracket 11 is connected to multiple material rotation mechanisms 2, multiple materials can be loaded at one time, realizing simultaneous loading of multiple stations.

[0032] Preferably, a reinforcing rod 13 is connected between the ends of the object carrier brackets 11 on both sides.

[0033] In order to increase the structural strength of the rotating frame 1 , the present application provides a reinforcing rod 13 between the ends of the object carriers 11 on both sides.

[0034] Preferably, the rotation drive mechanism 3 includes a drive motor 31 ; the drive motor 31 is directly drive-connected to the rotating arm 12 , or the drive motor 31 is drive-connected to the rotating arm 12 through a transmission mechanism, and the drive motor 31 drives the rotating arm 12 to rotate.

[0035] More preferably, the driving mechanism also includes a reducer 32 and a rotating seat 33, the rotating seat 33 is fixedly connected to the rotating arm 12, the driving motor 31 is drivingly connected to the reducer 32, and the output shaft of the reducer 32 is connected to the rotating seat 33; the driving motor 31 drives the rotating seat 33 to rotate through the reducer 32.

[0036] See also Figure 6 , and also includes a fixed frame 4, wherein the fixed frame 4 includes a vertical bracket 42 and a horizontal bracket 41, and the horizontal bracket 41 is fixedly connected to the driving motor 31 and the reducer 32.

Rotating struts 22 are respectively hinged to both sides of the lower end of the vertical substrate 21. A driving unit is provided in the middle of the vertical substrate 21. The driving unit is drivingly connected to a driving plate 28 and can drive the driving plate 28 to move up and down. The driving plate 28 is connected to the rotating struts 22 through a transmission unit. When the driving plate 28 moves up and down, the driving plate 28 drives the rotating struts 22 to rotate relative to the vertical substrate 21 through the transmission unit.

[0039] This technical solution is mainly aimed at flexible objects. The material spreading mechanism uses two rotating struts 22 to open and close, so as to fix the flexible object and at the same time spread the surface of the flexible object. When performing the spreading operation, the driving unit drives the transmission unit to act, driving the rotating struts 22 to rotate; the two rotating struts 22 rotate towards each other or away from each other, so as to realize the spreading of the flexible object.

A slot 25 inserted into the vertical substrate 21 is provided at the upper end of the rotating head 23. And a rotating shaft 214 is provided at the upper end of the rotating head 23. The upper end of the rotating head 23 is inserted into the vertical substrate 21 and is hinged to the vertical plate through the rotating shaft 214. The rotating head 23 can rotate relative to the vertical substrate 21. Preferably, the transmission unit includes a main transmission rod 26. One end of the main transmission rod 26 is connected to the rotating head 23 or the rotating strut 22. The other end of the main transmission rod 26 is hinged to a secondary transmission rod 27. The driving plate 28 is hinged to the secondary transmission rod 27.

[0041] To facilitate driving the rotation of the rotating struts 22, the technical solution of this application connects a rotating head 23 to the upper end of the rotating struts 22. The rotating head 23 is inserted into the vertical substrate 21 and is hinged through the rotating shaft 214, so that the rotating head 23 can rotate relative to the vertical substrate 21. Secondly, the transmission unit uses the cooperation of the main transmission rod 26 and the secondary transmission rod 27.

During application, to make the driving smooth, a speed reducer is also provided. The speed reducer is drivingly connected to the rotary motor 211. At the same time, for convenient connection, the speed reducer is connected to the vertical substrate 21 through the upper fixing plate 213, and the vertical substrate 21 is driven to rotate by driving the rotation of the upper fixing plate 213. For convenient setting or installation, a transmission mechanism 212 is provided between the rotary motor 211 and the speed reducer.
