A square groove 201 is opened at the bottom of the fixing frame 2, a mounting rod 29 is arranged inside the square groove 201, and a plurality of support blocks 30 are sleeved outside the mounting rod 29. As Figure 4As shown in the figure, the rightmost support block A is fixedly arranged inside the fixed frame 2, and the remaining support blocks 30 are all slidably arranged inside the square groove 201. Two transmission plates 16 are rotatably arranged on each support block 30. Connecting columns 18 are arranged at both ends of the transmission plate 16, and the transmission plates 16 are hinged to each other head and tail through the connecting columns 18. An activity frame 3 is slidably arranged on the fixed frame 2. A groove 301 is opened at the top of the activity frame 3, and a rotating disc 4 is rotatably arranged inside the groove 301. The groove 301 is an arc groove, and the rotating disc 4 is slidably engaged inside the arc groove. A support column 5 is vertically arranged on the rotating disc 4. An activity column 6 is slidably arranged at the top of the support column 5. A suspension plate 7 for suspending the workpiece is horizontally arranged at the top of the activity column 6;

[0034] Guide blocks 31 are arranged at the bottom of the activity frame 3. Rollers 20 are arranged at the bottom of the activity frame 3 to facilitate the movement of the activity frame 3 along the base 1. Two groups of limit blocks 19 are slidably arranged at the bottom of the activity frame 3. Thumb rods 17 are slidably arranged inside two connecting columns 18 rotatably connected to the limit blocks 19. The top ends of the thumb rods 17 penetrate into the groove 301 and are in contact with the rotating disc 4. A guide block 31 is arranged at the bottom of the rotating disc 4. A guide groove 311 is opened on the guide block 31. A fixed rod 33 and a cushion block 32 are arranged on the base 1. A baffle 34 is arranged at the top end of the fixed rod 33, and the baffle 34 is fixed through a pin 35;

[0035] A driving mechanism is connected to the rotating plate 16. The driving mechanism drives the rotating plate 16 to rotate. The rotating plate 16 drives the activity frame 3 to slide along the fixed frame 2 through cooperation with the limit block 19. The activity frame 3 drives the workpiece to move to the spraying area through cooperation with the rotating disc 4. The baffle 34 drives the rotating disc 4 to rotate by squeezing the support column 5, and the rotating disc 4 adjusts the spraying position of the workpiece by rotating.

[0036] As Figure 1-8 shown, as a preferred embodiment of the present invention, the driving mechanism includes a transmission block 14, a threaded rod 13 and a motor 12. A transmission block 14 is arranged at the bottom of the connecting column 18. A threaded groove 15 is opened inside the transmission block 14. A threaded rod 13 is arranged inside the threaded groove 15. The thread directions of the two groups of threaded rods 13 are opposite. An installation plate 11 is slidably arranged on the outer side wall of the fixed frame 2. One end of the installation plate 11 is provided with a motor 12. The motor 12 is a double-shaft motor. The rotating end of the motor 12 is connected to the threaded rod 13. The motor 12 drives the threaded rods 13 on both outer sides to rotate. The threaded rods 13 drive the transmission blocks 14 to move. The two transmission blocks 14 approach or move away from each other. Multiple transmission plates 16 are hinged to each other to form a scissor structure. The scissor structure is located between the activity frame 3 and the installation plate 11. The two transmission blocks 14 approach each other and drive the scissor structure to expand outwards. The scissor structure drives the activity frame 3 to slide leftwards along the fixed frame 2 (i.e., Figure 2In the direction of the arrow shown), multiple spraying nozzles 251 on the movable plate 25 spray the workpiece. After the side of the workpiece close to the spraying nozzle 251 is sprayed, the movable frame 3 moves to the position of the cushion block 32. The cushion block 32 jacks up the ejector rod 17, and the ejector rod 17 jacks up the rotating disc 4. The guide block 31 disengages from the movable frame 3, and the locking of the rotating disc 4 is released (i.e., the rotating disc 4 can rotate). The support column 5 contacts the baffle 34, and the baffle 34 presses the support column 5, so that the support column 5 cannot move further. The rotating disc 4 drives the workpiece to rotate. After rotating a certain angle, the motor 12 reverses, the movable frame 3 moves in the reverse direction and resets. The ejector rod 17 disengages from the cushion block 32, and the rotating disc 4 and the guide block 31 descend. A guide groove 311 is provided on the guide block 31, so that when the guide block 31 descends, the guide block 31 drives the rotating disc 4 to rotate. When the guide block 31 is at the position on both sides of the movable frame 3 (i.e., Figure 5 the position shown), the rotating disc 4 is locked and cannot rotate, and the guide block 31 guides the rotation of the rotating disc 4, so that the rotating disc 4 rotates by the same angle each time; Figure 4 There are four groups of guide blocks 31, so that the rotating disc 4 rotates 90 degrees each time. The movable frame 3 drives the workpiece to move back and forth left and right, ensuring that all four surfaces of the workpiece can be sprayed. Compared with the traditional suspension spraying, there is no need to re-clamp the workpiece, and the outer surface of the workpiece is sprayed in turn, and the spraying of the workpiece is more uniform, ensuring the spraying quality of the workpiece.

[0037] As Figure 4-8 shown, as a preferred embodiment of the present invention, a connecting block 501 is arranged outside the support column 5, and a support rod 36 and a sleeve 39 are respectively arranged outside the two connecting blocks 501. An expansion rod 38 is slidably arranged inside the sleeve 39, and the expansion rod 38 is elastically installed on the sleeve 39. One end of the expansion rod 38 passes through the sleeve 39 and is provided with a fixed block 381, and the fixed block 381 is a rubber block.

[0038] As Figure 4-8 shown, as a preferred embodiment of the present invention, one end of the support rod 36 is provided with a rotating frame 37, and a movable block 371 is slidably arranged outside the rotating frame 37. The movable block 371 is slidably sleeved outside the expansion rod 38.

[0039] As Figure 2-8As shown, as a preferred embodiment of the present invention, a plurality of card slots 502 are provided on the outside of the support column 5. A clamping plate 40 is provided on the movable column 6. The clamping plate 40 is elastically mounted on the movable column 6 through a spring. Fixed teeth 41 matching the card slots 502 are provided on the clamping plate 40. A handle 9 is provided at the center of the hanging plate 7. A pulling plate 10 is slidably provided on the handle 9. A connecting rope 8 is provided inside the movable column 6. One end of the connecting rope 8 is connected to the clamping plate 40, and the other end of the connecting rope 8 is connected to the pulling plate 10. By driving the hanging plate 7 to move through the handle 9, the hanging plate 7 suspends a workpiece through the lower suspension rod. Pulling up the pulling plate 10, the pulling plate 10 pulls the clamping plate 40 through the connecting rope 8, so that the clamping plate 40 and the fixed teeth 41 contract into the movable column 6. The movable column 6 at the bottom of the hanging plate 7 is inserted downward into the support column 5, and the hanging plate 7 drives the workpiece to move downward. The workpiece presses down on multiple rotating frames 37, and the rotating frames 37 turn downward. The movable block 371 drives the telescopic rod 38 to move, and multiple fixed blocks 381 approach each other and squeeze and fix the side of the workpiece. After the workpiece is fixed, the handle 9 is released, the pulling plate 10 resets downward, the clamping plate 40 pops out of the movable column 6, and the fixed teeth 41 snap downward into the card slots 502, so that the hanging plate 7 cannot reset upward, and the hanging plate 7 limits the workpiece below through the suspension rod.

[0040] As Figure 4 As shown, as a preferred embodiment of the present invention, an elastic column 27 is provided at the center of the groove 301. A return spring 28 is sleeved outside the elastic column 27. The elastic column 27 is elastically mounted inside the groove 301 through the return spring 28. The bottom end of the return spring 28 is connected to the movable frame 3. The rotating rod 27 passes through the rotating disk 4 and is slidably matched with it. The rotating disk 4 drives the elastic column 27 to rise, and the return spring 28 pulls the elastic column 27 downward through elasticity, which is convenient for the rotating disk 4 to reset downward.

[0041] As Figure 1-3 As shown, as a preferred embodiment of the present invention, a lead screw 26 is provided inside the guide rail 23. A lifting block 24 is sleeved outside the lead screw 26. The lifting block 24 is connected to the movable plate 25.

[0042] In the above embodiments of the present invention, a robot automatic spraying device is provided. The hanging plate 7 suspends and moves the workpiece to be sprayed. The support column 5 fixes the workpiece through the externally provided fixing block 381 to prevent the workpiece from shaking during spraying. The movable frame 3 drives the workpiece to move leftward. Multiple spraying ports 251 on the movable plate 25 spray the workpiece. When the movable frame 3 moves to the position of the cushion block 32, the cushion block 32 pushes the ejector rod 17 upward, and the ejector rod 17 pushes the rotating disk 4 upward. The guiding block 31 disengages from the movable frame 3, and the locking of the rotating disk 4 is released. After the rotating disk 4 rotates a certain angle, the motor 12 reverses, the movable frame 3 moves in the reverse direction and resets. The ejector rod 17 disengages from the cushion block 32, the rotating disk 4 and the guiding block 31 descend, and the guiding block 31 drives the rotating disk 4 to rotate, rotating the unsprayed side of the workpiece to the front of the device for spraying through the spraying port 251, ensuring that all four sides of the workpiece can be sprayed.

[0043] As described above, the above is only the specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure.
