Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 to FIG. 4 , a spraying device 10 suitable for a workpiece includes a mounting frame 11 , a spray gun 12 and a paint bucket 13 containing paint. A paint bucket 13 is mounted to the mounting frame 11 and communicated to the spray gun 12 through a pipeline 14 to supply paint to the spray gun 12 .

Specifically, the spraying device 10 suitable for a workpiece further includes: a hanger 15, a guide rail 18, a drive chain, a drive motor 20, an insulating mounting frame 21, an elastic conductive slide 214, a first electrostatic generator 22 and a second electrostatic generator twenty three.

The hanger 15 is used to mount the workpiece to be sprayed. The guide rail 18 is used to guide the hanger 15 to move. The drive chain is used to drive the hanger 15 to move. The drive motor 20 is used to drive the drive train. The first electrostatic generator 22 and the second electrostatic generator 23 discharge static electricity with different polarities respectively, so that the paint can be uniformly adsorbed on the surface of the workpiece, and the spraying quality and spraying efficiency are improved. The insulating mounting frame 21 and the elastic conductive sliding sheet 214 are used to deliver static electricity to the hanger 15 .

As a specific structure, the guide rail 18 is provided above the mounting frame 11 . The drive chain is arranged in the guide rail 18 . The drive motor 20 is connected to the drive train. The pylons 15 are connected to the drive chain to move along the guide rails 18 when the drive motor 20 drives the drive chain. The insulating mounting frame 21 is mounted to the rail 18 side. The elastic conductive sliding sheet 214 is fixed to the insulating mounting frame 21 . The first electrostatic generator 22 is electrically connected to the spray gun 12, and the second electrostatic generator 23 is electrically connected to the elastic conductive sliding piece 214, so that the spray gun 12 and the hanger 15 can be charged with different polarities of static electricity respectively. Since the insulating mounting frame 21 is made of insulating material, the electric charges on the elastic conductive sliding sheet 214 cannot be conducted to other components through the insulating mounting frame 21 .

Further, the hanger 15 includes: an insulating hanger 151 , an insulating protective cover 152 , a metal conductive plate 16 and a conductive column 17 . The upper end of the insulating hanging rod 151 is connected to the drive chain. The insulating protective cover 152 is connected to the lower end of the insulating hanging rod 151 . The metal conductive plate 16 is fixed to the inner side of the insulating protective cover 152 . The conductive column 17 passes through the insulating protective cover 152 and is connected to the metal conductive plate 16 at one end and in contact with the elastic conductive sliding sheet 214 at the other end.

Specifically, when the spraying work is performed, the workpiece is mounted on the hanger 15, the drive motor 20 starts the driving drive chain to rotate, and the drive chain drives the rotating hanger 15 to move along the guide rail 18 when rotating, until the hanger 15 moves to the spraying position. When in position, the spray gun 12 sprays the workpiece on the hanger 15 . Since the first electrostatic generator 22 is electrically connected to the spray gun 12, and the second electrostatic generator 23 is electrically connected to the elastic conductive slide 214, the spray gun 12 and the elastic conductive slide 214 have static electricity of different polarities. When the hanger 15 moves to the spraying position, the other end of the conductive column 17 contacts with the elastic conductive slide 214 , so that the hanger 15 has static electricity with the same polarity as the elastic conductive slide 214 . That is to say, when the hanger 15 moves to the spraying position, the polarity of the static electricity carried by the hanger 15 is opposite to the polarity of the static electricity carried by the paint sprayed by the spray gun 12 . In this way, when the spray gun 12 sprays, the paint can be quickly and uniformly adsorbed to the surface of the workpiece through the attractive force between static electricity with opposite polarities, and the spraying efficiency is high and the spraying quality is good. Since the insulating hanger 151 is made of insulating material, the electric charge on the hanger 15 will not be conducted to the parts to which it is connected.

The above-mentioned workpiece may be an insulating workpiece or a metal workpiece. The spraying device 10 suitable for workpieces has the same spraying effect on insulating workpieces and metal workpieces.

As a specific embodiment, the insulating mounting frame 21 includes: two connecting rods 211 and a guide rod 212 . Two connecting rods 211 are connected to one side of the guide rail 18 . Both ends of the guide rod 212 are respectively connected to one end of the two connecting rods 211 away from the guide rail 18 . The elastic conductive sliding piece 214 is fixed to the guide rod 212 . The connecting rod 211 and the guide rod 212 are made of insulating material.

Further, the guide rod 212 is formed with a guide groove 213 . The guide grooves 213 are used to guide the movement of the conductive posts 17 . The elastic conductive sliding sheet 214 is fixed into the guide groove 213 . When the hanger 15 moves to the spraying position, a portion of the conductive column 17 is inserted into the guide groove 213 and contacts the elastic conductive sliding piece 214 . In this way, the static electricity on the elastic conductive slider 214 is transmitted to the metal conductive plate 16 through the conductive column 17 , so that the metal conductive plate 16 is charged with static electricity, and the polarity of the static electricity is the same as that of the paint sprayed by the spray gun 12 . of opposite polarity.

As a specific embodiment, baffles 153 are formed on both sides of the insulating protective cover 152 . The baffle 153 can prevent the paint sprayed from the spray gun 12 from being sprayed around.

As a specific embodiment, the inner side of the insulating protective cover 152 is provided with a buckle 154 . The clips 154 are used to mount the workpiece.

As a specific embodiment, the insulating protective cover 152 is connected to the lower end of the insulating hanging rod 151 through the hook 155 . In this way, it is convenient to disassemble the insulating hanging rod 151, and to facilitate cleaning and installation.

As a specific embodiment, the first electrostatic generator 22 is a positive electricity generator. The second electrostatic generator 23 is a negative electricity generator. In this way, the spray gun 12 is charged with positive static electricity, and the elastic conductive slide 214 is charged with negative static electricity.

As an optional way, the first electrostatic generator is a negative electricity generator. The second electrostatic generator is a positive generator. In this way, the spray gun has negative static electricity, and the elastic conductive slide has positive static electricity.

As a specific embodiment, the spraying device 10 suitable for a workpiece further includes a discharge assembly 24 . The discharge assembly 24 is arranged on one side of the guide rail 18 and can be used to discharge the rotating hanger 15 so as to prevent the workpiece and the rotating hanger 15 from continuing to be electrostatically charged after the spraying work is completed, thereby harming the workers.

Specifically, the discharge assembly 24 includes: a discharge block 241 , a discharge sheet 242 and a ground wire 243 . One end of the discharge block 241 is connected to one side of the guide rail 18 . The discharge sheet 242 is connected to the other end of the discharge block 241 . One end of the ground wire 243 is connected to the discharge block 241 and the other end is grounded. When the hanger 15 moves to the position of the discharge assembly 24 driven by the drive chain and contacts with the discharge piece 242, the static electricity on the hanger 15 is completely discharged through the discharge block 241 and the ground wire 243 through the discharge piece 242.

As a specific structure, the mounting frame 11 is separated by a spacer for spraying and a space for electrostatic discharge. The first electrostatic generator 22 and the second electrostatic generator 23 are located in the spraying space. The discharge assembly 24 is located in the electrostatic discharge space.
