Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 4, a spin coating apparatus 10 for a workpiece includes: a mounting frame 11, a spraying device 12 and a paint bucket 13 containing paint. The paint bucket 13 is mounted to the mounting frame 11 and communicates to the painting device 12 through a pipe to supply paint to the painting device 12.
Specifically, the spin coating device 10 for a workpiece further includes: the device comprises a conductive hanger 14, a mounting plate 15, a rotating motor 16, a conductive rotating shaft 17, a first static generator 18, a second static generator 19 and a control switch 20. The conductive hanger 14 is used to mount the workpiece 100. The mounting plate 15 is mounted to the mounting bracket 11. The conductive hanger 14 is rotatably supported above the mounting plate 15 by a conductive rotating shaft 17. The conductive rotating shaft 17 has one end connected to the conductive hanger 14 and the other end connected to a motor shaft of the rotating motor 16. The rotary motor 16 is mounted below the mounting plate 15 and is electrically connected to the control switch 20. The first electrostatic generator 18 is electrically connected to the spray coating device 12. The second electrostatic generator 19 is electrically connected to the conductive rotating shaft 17.
Specifically, when the painting operation is performed, the workpiece 100 is attached to the conductive hanger 14, and the rotary motor 16 is driven by pressing the control switch 20. After the rotating motor 16 is started, the conductive hanger 14 is driven to rotate by the conductive rotating shaft 17, so as to drive the workpiece 100 mounted on the conductive hanger 14 to rotate. At this time, the spraying apparatus 12 sprays the workpiece 100 on the conductive hanger 14. Since the first electrostatic generator 18 is electrically connected to the painting device 12 and the second electrostatic generator 19 is electrically connected to the conductive rotating shaft 17, the conductive rotating shaft 17 transmits static electricity to the conductive hanger 14 when the painting device 12 paints the workpiece 100 on the conductive hanger 14, so that the painting device 12 and the conductive hanger 14 are charged with static electricity of different polarities. That is, when painting the workpiece 100 on the conductive hanger 14, the conductive hanger 14 has an electrostatic polarity that is opposite to the polarity of the electrostatic charge of the coating material sprayed by the painting device 12. When the coating device 12 is used for coating, the coating can be quickly and uniformly adsorbed on the surface of the workpiece 100 by the attraction force between the static electricity with opposite polarities, and the coating efficiency is high and the coating quality is good.
The workpiece 100 may be an insulating workpiece 100 or a metal workpiece 100. The rotary coating device 10 for workpieces has the same coating effect on the insulating workpiece 100 and the metal workpiece 100.
Further, the spin coating apparatus 10 for a workpiece further includes a discharge assembly 25. A discharge assembly 25 is provided on the underside of the mounting plate 15 for discharging the electrically conductive hanger 14.
Specifically, the discharge assembly 25 includes: relay 251, solenoid valve 252 and cylinder 253. The relay 251 is electrically connected to the control switch 20. The two ends of the electromagnetic gas valve 252 are respectively connected with the relay 251 and the cylinder 253. The rod of the air cylinder 253 moves between contacting the conductive rotating shaft 17 and disengaging the conductive rotating shaft 17.
Specifically, when the control switch 20 is pressed, the control switch 20 activates the rotating motor 16 and simultaneously the rod of the control cylinder 253 is retracted away from the conductive rotating shaft 17, so that the second static electricity generator 19 can transmit static electricity to the conductive hanger 14 through the conductive rotating shaft 17. When the control switch 20 stops being pressed, the rotating motor 16 stops working, the relay 251 controls the electromagnetic air valve 252 to push the air cylinder 253, the piston of the air cylinder 253 pushes the cylinder rod to extend until contacting the conductive rotating shaft 17 under the pushing of the air released by the electromagnetic air valve 252, and therefore high-voltage static electricity remained on the conductive hanger 14 is guided to the ground through the ground wire, and electric sparks are prevented from being generated and workers are prevented from getting electric shock. Then the gas direction is controlled by controlling the electromagnetic gas valve 252, the piston of the air cylinder 253 is returned to wait for the next execution.
As a specific embodiment, the electrically conductive rotating shaft 17 is connected to the rotating electrical machine 16 through a coupling 21. The second electrostatic generator 19 is electrically connected to the conductive rotating shaft 17 through a brush 22.
Specifically, the brush 22 is fixed to a housing of the coupling 21, and has one end protruding into the coupling 21 to contact the conductive rotating shaft 17 and the other end into which a connection terminal of the second electrostatic generator 19 is inserted to transmit the static electricity of the second electrostatic generator 19 to the conductive rotating shaft 17.
Further, the position of the conductive rotating shaft 17 for contacting the brush 22 is also provided with a conductive bearing. The brush 22 contacts the conductive bearing, thereby transmitting static electricity to the conductive rotating shaft 17 through the conductive bearing. This can prevent the brush 22 from directly coming into frictional contact with the conductive rotary shaft 17, protect the conductive rotary shaft 17 and the brush 22, and reduce wear therebetween.
As a specific embodiment, the conductive rotating shaft 17 is rotatably connected to the mounting plate 15 through a rotating support bracket 23 having a through hole 231 therein, and has a simple structure.
As a specific embodiment, a rotation bearing 24 is disposed between the conductive rotation shaft 17 and the wall of the through hole 231 to ensure the rotation stability of the conductive rotation shaft 17.
In one specific embodiment, the first electrostatic generator 18 is a positive electrical generator. The second electrostatic generator 19 is a negative electric generator. Thus, the spray coating device 12 is charged with positive static electricity, while the conductive hanger 14 is charged with negative static electricity.
As an alternative embodiment, the first electrostatic generator is a negative electric generator. The second electrostatic generator is a positive generator. Thus, the spraying equipment is charged with negative static electricity, and the conductive hanger is charged with positive static electricity.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
