The annular groove and the annular protrusion provided at one end of the rotating shaft 10 close to the bearing column 2 make the annular protrusion provided at one end of the rotating shaft 10 close to the bearing column 2 slide in the annular groove opened on the surface of the bearing column 2, thereby passing through the bearing column 2. To bear the weight of the rotating shaft 10 and the machine on the rotating shaft 10, it does not need to be borne by the output shaft of the No. 1 motor 8 to prevent the No. 1 motor 8 from being damaged due to the excessive weight of the machine on the rotating shaft 10, so that the rotating shaft 10 can be As shown in Figure 1, the No. 5 motor 9 fixedly connected with the rotating shaft 10 starts, and drives the No. 1 rod 11 fixedly connected with the output shaft of the No. 5 motor 9 to rotate around the output shaft of the No. 5 motor 9, and at the same time The No. 2 motor 12 fixedly connected to the No. 1 rod 11 is activated, and drives the No. 2 rod 13 that is fixedly connected to the output shaft of the No. 2 motor 12 to rotate around the output shaft of the No. 2 motor 12, while the No. 3 motor that is fixedly connected to the No. 2 rod 13 rotates 15 starts, and drives the No. 3 rod 19 that is fixedly connected with the output shaft of the No. 3 motor 15 to also rotate, so that the No. 3 rod 19 rotates around the output shaft of the No. 3 motor 15, and passes through the rotating shaft 10, No. The cooperation of No. 19 and No. 1 motor 8, No. 5 motor 9, No. 2 motor 12, and No. 3 motor 15 enables the mechanical arm of the present invention to have a higher degree of freedom to drive the spraying assembly 5 to spray the surface of the workpiece .

The atomizing nozzle 25 is located at the end of the No. 3 rod 19 away from the No. 2 rod 13, the atomizing nozzle 25 is fixedly connected to the No. 3 rod 19, and the atomizing nozzle 25 is communicated with the No. 3 pipeline 24 .

The atomized paint generated by the spraying equipment 3 enters the No. 1 pipeline 21 communicated with the spraying equipment 3, then enters the No. 1 hose 22 communicated with the No. 1 pipeline 21, and then enters the No. 1 hose 22 communicated with Inside the No. 2 hose 23 , and then into the No. 3 pipeline 24 that communicates with the No. 2 hose 23 , and finally sprays onto the surface of the workpiece through the atomizing nozzle 25 that communicates with the No. 3 pipeline 24 .

Before the formal spraying, it is necessary to perform pre-dust removal treatment, and the annular cover 30 is moved to the surface of the workpiece by the action of the moving component 4, so that the bottom of the annular cover 30 is attached to the surface of the workpiece, and the No. 4 motor 28 on the fixed plate 27 is activated, Drive the rotating shaft 29 fixedly connected with the output shaft of the No. 4 motor 28 to rotate, and drive the fan blade 31 fixedly connected with the rotating shaft 29 to move to form a pressure difference inside and outside the fan blade 31, so that the debris on the surface of the workpiece is sucked into the suction hole 36, Then enter the No. 5 pipeline 35 that communicates with the suction hole 36, then enter the No. 4 pipeline 34 communicated with the No. 5 pipeline 35, and then enter the No. 4 hose 33 communicated with the No. 4 pipeline 34, and then enter the The No. 3 hose 32, which is connected to the No. 4 hose 33, finally enters the box 26, and then enters the next process. During spraying, the speed of the atomized paint sprayed from the atomizing nozzle 25 is high, so there will be a small amount of paint The atomized paint will be scattered around the atomizing nozzle because the speed is too high in the future after contacting with the workpiece, and the No. 4 motor 28 on the fixed plate 27 will be activated to drive the rotating shaft 29 that is fixedly connected to the output shaft of the No. 4 motor 28. Rotation, drives the movement of the fan blade 31 fixedly connected with the rotating shaft 29 to form a pressure difference inside and outside the fan blade 31, so that the atomized paint escaping around the spraying place can be sucked into the suction hole 36, and then enter the five holes that communicate with the suction hole 36. into the No. 4 pipeline 35, then into the No. 4 pipeline 34 connected with the No. 5 pipeline 35, then into the No. 4 hose 33 connected with the No. 4 pipeline 34, and then into the No. 3 hose connected with the No. 4 hose 33 The hose 32 finally enters the box 26. As shown in Figure 2, since the paint is sprayed from the atomizing nozzle 25 during spraying, the sprayed paint is fan-shaped, and the paint atomization phenomenon at the edge of the fan-shaped edge is the largest, so In the present invention, the length of the annular cover 30 is set to be greater than the length of the atomizing nozzle 25. During operation, the bottom of the annular cover 30 is close to the surface of the machined part but not in contact, so that the leakage of paint can be reduced as much as possible, resulting in Air pollution, and the length of the annular cover 30 is set to be greater than the length of the atomizing nozzle 25, to give the atomizing nozzle 25 enough working space, and at the same time because the suction hole 36 absorbs the atomized paint, there will be a small amount of atomized paint sticking to it. The inner wall of the No. 5 pipe 35, therefore, the annular cover 30 is formed by splicing a plurality of baffles 47 and elastic rubbers 46, and the baffles 47 are hinged with the No. 3 rod 19. As shown in FIG. 6, since the baffle 47 is a It is arc-shaped, so a hinge block is fixedly connected above the baffle 47 to facilitate the hinged connection between the baffle 47 and the third rod 19, and an elastic rubber 46 is fixedly connected between the two adjacent baffles 47, and the baffle 47 is connected by the elastic rubber 46. It is connected to form a ring, and the baffle 47 is hinged with the third rod 19, so that the baffle 47 can move relative to the third rod 19 as a whole, as shown in FIG. 5, that is, the baffle 47 is relative to the third rod 19. A schematic diagram of the baffles 47 moving away from each other during rotation, because the elastic rubber 46 is fixedly connected between two adjacent baffles 47, so even if the baffles 47 are far away from each other during rotation, the annular cover 30 will not generate a gap .

When the gas absorbed by the dust removal assembly 6 enters the filter box 37, the metal debris in the gas can be adsorbed on the surface of the magnetic suction net 38 through the magnetic suction net 38, and the activated carbon layer 39 arranged under the magnetic suction net 38 makes the gas The dust particles in the air can be absorbed, and finally the atomized paint in the air can be absorbed by the water absorbing sponge layer 41, and finally the filtered air is discharged through the air outlet pipe 42.

As shown in FIG. 2 , after the suction hole 36 sucks the atomized paint, the paint will slowly dry and eventually block the hose, so that it cannot continue to be used. Therefore, in the present invention, the third rod 19 is fixedly connected with the baffle 47 at the hinged position. The cleaning bag 43 is filled with cleaning liquid, such as rosin, after the paint is sprayed, the third rod 19 drives the annular cover 30 away from the workpiece where the processing is completed, and presses the annular cover 30 down, because the cleaning bag 43 is fixed It is connected at the hinge joint between the No. 3 rod 19 and the baffle 47. Therefore, when the annular cover 30 is pressed down, the baffle 47 rotates and pulls the cleaning bag 43 to stretch. At this time, the cleaning liquid inside the cleaning bag 43 will be squeezed, and the cleaning liquid will be released from the cleaning bag 43. The pressure valve on the surface of the cleaning bag 43 flows out, and the No. 4 motor 28 is activated at the same time, and an airflow is formed inside the hose to suck the outflowing cleaning liquid into the hose. Therefore, the cleaning liquid will clean the inner wall of the hose during the suction process. In order to prevent the paint from drying slowly and eventually blocking the hose, the cleaning bag 43 is formed in a ring shape and tightly attached to the inner wall of the No.

Since the atomizing nozzle 25 is circular, the annular cover 30 is annular and surrounds the atomizing nozzle 25, and the suction hole 36 is located on the annular cover 30, as shown in FIG. Therefore, the number of suction holes 36 is not less than four, and it is ensured that the four suction holes 36 are located at the positions shown in FIG. 3 .

The paint mist coagulant has good cohesion to the atomized paint, so the paint mist coagulant is arranged in the water-absorbing sponge layer 41. When the absorbed gas passes through the water-absorbing sponge layer 41, the atomized paint in the gas will mix with the paint mist. The combination of the coagulant enables the gaseous atomized paint to agglomerate, thereby preventing the atomized paint from being discharged into the air and polluting the environment.

As shown in FIG. 4 , the No. 4 pipeline 34 is located around the No. 3 pipeline 24, and the number of the No. 4 pipeline 34 is four, so that the No. 4 pipeline can timely enter the gas absorbed by the suction hole 36 into the No. 4 pipeline through the No. 5 pipeline 35. It can be transported out in time to prevent the absorption effect from being reduced due to the small number of No. 4 pipelines 34 and the unsmooth gas flow.
