Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 6 As shown.

[0024] Example: See Figure 1 , Figure 2 A rotating mechanism includes: a fixed frame 2 and a rotating frame 1. The rotating frame 1 has a accommodating space in the middle and a load-bearing bracket 12 at each end. A rotating drive device 5 is provided between the fixed frame 2 and the rotating frame 1. The rotating drive device 5 can drive the rotating frame 1 to rotate relative to the fixed frame 2. The load-bearing bracket 12 is located outside the accommodating space and can rotate around the accommodating space.

[0025] In implementation of the technical solution of this application, for example, the fixing frame 2 is configured as an inverted U-shape, and the middle of the rotating frame 1 forms an accommodating space, which can hold the processing device 3, such as a row of spraying robots; to enable the workpiece to rotate around the processing device 3, a carrying support 12 is provided on the outer side of the rotating frame 1. For example, the carrying support 12 can carry a carrying fixing device 4, such as a carrying clamp, to fix the workpiece; the carrying support 12 can also be a carrying platform, etc. When the workpiece is very heavy and will not shift during rotation, a carrying platform can be used to place the workpiece on the carrying platform; when it needs to be fixed, a carrying fixture can be used to limit and fix the workpiece through some limiting structures. Of course, ropes or the like can also be used to bind and fix the workpiece. The workpiece is driven to rotate around the processing device 3 by a rotating frame 1 and a carrying support 12. At least two workstations can be set up: one for loading / unloading and the other for processing. The loading and unloading workstations repeat as follows: The loading / unloading workstation loads the workpiece, then the rotating frame 1 rotates, and the workpiece enters the processing station. Simultaneously, the loading / unloading workstation loads the workpiece again. Then, the rotating frame 1 rotates, and the workpiece enters the loading / unloading workstation for unloading. After unloading, the workpiece is loaded again. The subsequently loaded workpiece enters the processing station for processing, and this process repeats. Alternatively, the loading / unloading workstation can be divided into two workstations.

[0026] When divided into two workstations, the rotating frame 1 rotates 180 degrees at a time; workers do not need to move between workstations; they can stay near the loading and unloading workstations; reducing the delay of movement time, and also avoiding entering the vicinity of the processing workstations, which can effectively improve production efficiency and reduce the harm of the processing environment to the human body.

[0027] See Figure 2 , Figure 6 The fixed frame 2 includes a vertical support 22 and a horizontal support 21 connected to the vertical support 22. A rotating arm 11 is connected between the two load supports 12 at both ends. The rotating drive device 5 is fixed to the horizontal support 21 and drivenly connected to the rotating arm 11.

[0028] The fixing frame 2 consists of a vertical support 22 and a horizontal support 21. The vertical support 22 is used for support, and the horizontal support 21 is used for connection. The fixing clamp can be an inverted L-shape or an inverted U-shape. That is, one vertical support 22 can be set, in which case the horizontal support 21 is connected to the upper end of the vertical support 22, and the length of the horizontal support 21 is not less than the length of the rotating arm 11; or two vertical supports 22 can be set, in which case the two vertical supports 22 are located on both sides, and the two ends of the horizontal support 21 are respectively connected to the corresponding vertical support 22, and the length of the horizontal support 21 is not less than the length of the straight arm.

[0029] See Figure 2 , Figure 3 as well as Figure 4 , Figure 5 The rotary drive device 5 includes a fixed plate 52 fixedly connected to the horizontal support 21 and a rotary motor 51 fixed to the fixed plate 52. The rotary motor 51 is connected to a rotary seat 55 and drives the rotary seat 55 to rotate. A connecting plate 53 is fixedly connected to the bottom of the rotary seat 55 and is connected to the rotary arm 11.

[0030] To facilitate the rotation of the rotating frame 1, this application uses a rotary motor 51 to drive its rotation. In specific implementation, the rotary motor 51 is fixed to the fixed plate 52 via a motor mount. The rotating shaft of the rotary motor 51 is driven to rotate the rotating seat 55, which in turn drives the connecting plate 53 and the rotating arm 11 to rotate, thereby driving the rotating frame 1 to rotate. Furthermore, in this embodiment, two rotating arms 11 are provided and are respectively connected to the lower end face of the connecting plate 53. To improve the structural strength of the two rotating arms 11, several reinforcing beams 14 are connected between the two rotating arms 11, two of which are located below the connecting plate 53 and are fixedly connected to the connecting plate 53.

[0031] Preferably, a speed reducer 54 is provided between the rotating base 55 and the rotating motor 51.

[0032] When the rotating frame 1 is driven to rotate by the rotary motor 51, the rotary motor 51 rotates at a relatively high speed, while the required rotational speed of the rotating frame 1 is relatively low. Therefore, a reducer 54 is installed between the rotating base 55 and the rotary motor 51. The reducer 54 can be an RV reducer. In a specific implementation, the rotating shaft of the rotary motor 51 is connected to the power input shaft of the reducer 54, and the power output shaft of the reducer 54 is connected to the rotating base 55. The rotary motor 51 can be a servo motor, etc.

[0033] See Figure 2 , Figure 6 The vertical support 22 includes two vertically arranged vertical beams 221, and multiple horizontally arranged lower longitudinal beams 222 are provided between the two vertical beams 221; the lower end of the vertical beams 221 is connected to a base plate 224, and a number of reinforcing plates 223 are connected between the base plate 224 and the vertical beams 221.

[0034] The vertical support 22 is constructed by splicing vertical beams 221 and lower longitudinal beams 222, resulting in a simple overall structure. To prevent excessive pressure on the ground from the vertical beams 221, which could damage the ground, a base plate 224 is installed at the lower end of the vertical beams 221. To enhance the overall structural strength, several reinforcing plates 223 are installed between the base plate 224 and the vertical beams 221. These reinforcing plates improve the strength of the lower end of the vertical beams 221.

[0035] See Figure 2 as well as Figure 6 The horizontal support 21 has a double-layer structure. Each layer includes two horizontally arranged crossbeams 211, and several upper longitudinal beams 212 are arranged between the two crossbeams 211. Multiple connecting blocks 213 are arranged between the two layers. The fixing plate 52 is fixed to the two upper longitudinal beams 212 located in the middle.

[0036] In this embodiment, the horizontal support 21 is designed as a double-layer structure, which improves the overall strength and allows the rotary motor 51 and other components to be concealed within it, preventing interference from other objects. Furthermore, to enhance structural strength, an intermediate beam is installed between the two upper longitudinal beams 212 when fixing the fixing plate 52, and this intermediate beam is fixedly connected to the fixing plate 52.

[0037] See Figure 3 , Figure 4 The cargo support 12 includes two cargo-carrying crossbeams 121, and multiple cargo-carrying longitudinal beams 122 are connected between the two cargo-carrying crossbeams 121.

[0038] The load-bearing bracket 12 can be a load-bearing plate, etc. In this embodiment, the load-bearing bracket 12 is used, which can improve the structural strength of the load-bearing bracket 12 and facilitate the installation of more load-bearing fixing devices 4. The load-bearing bracket 12 can be equipped with a connecting plate 53 as needed and connected to the connecting plate 53.

[0039] Preferably, both the load-bearing crossbeam 121 and the load-bearing longitudinal beam 122 are made of square steel.

[0040] Both the load-bearing crossbeam 121 and the load-bearing longitudinal beam 122 are made of square steel, which allows for wiring to be routed within the square steel, facilitating cable routing.

[0041] See Figure 3 , Figure 4 The main fixing plate 15 is connected to the middle of the inner side of the cargo support 12, and the auxiliary connecting plate 16 is connected to the end of the rotating arm 11. The main fixing plate 15 and the auxiliary connecting plate 16 are fixedly connected.

[0042] In this embodiment, the rotating arm 11 can also be made of square steel. When the load support 12 is connected to the rotating arm 11, the contact area is small. If welding is used, it will be difficult to disassemble and assemble later. Therefore, this application adopts a main fixing plate 15 in the middle of the inner side of the load support 12 and a secondary fixing plate 52 in the end of the rotating arm 11. The main fixing plate 15 and the secondary fixing plate 52 can be connected by bolts.

[0043] Preferably, a reinforcing rod 13 is provided between the two ends of the two load-bearing brackets 12, and the reinforcing rod 13 is also connected to a secondary fixing plate 52. A corresponding main fixing plate 15 is provided at the inner end of the load-bearing bracket 12, and the main fixing plate 15 is fixedly connected to the corresponding secondary fixing plate 52.

[0044] To improve the structural strength of the load-bearing bracket 12, this application also provides reinforcing rods 13 between both ends of the load-bearing bracket 12. At the same time, a main fixing plate 15 and a secondary fixing plate 52 are provided between the reinforcing rods 13 and the load-bearing bracket 12 to facilitate their connection.

[0045] See Figure 1 A multi-station processing device includes multiple processing devices and the aforementioned rotating mechanism, wherein the multiple processing devices are located in an accommodating space.
