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 5, a spray coating device 10 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 communicates through a conduit 14 to the spray gun 12 to supply paint to the spray gun 12.
Specifically, the spray coating device 10 for a workpiece further includes: the device comprises a rotary hanger 15, a guide rail 17, a driving chain, a driving motor 19, an insulating rack mounting plate 20, a metal rack 21, a first static generator 22 and a second static generator 23. The rotary hanger 15 is used for mounting a plurality of workpieces. The guide rail 17 guides the rotary hanger 15 to move. The drive chain is used to drive the rotary hanger 15. The drive motor 19 is used to drive the drive train. The metal rack 21 is adapted to engage with the rotary hanger 15 to rotate the rotary hanger 15. The first static generator 22 and the second static generator 23 respectively discharge static electricity with different polarities, so that the coating can be uniformly adsorbed on the surface of the workpiece, and the spraying quality and the spraying efficiency are improved.
Specifically, the guide rail 17 is provided above the mounting bracket 11. The drive chain is arranged in the guide rail 17. The drive motor 19 is connected to the drive chain. The rotary hanger 15 is connected to the drive chain to move along the guide rail 17 when the drive chain is driven by the drive motor 19. An insulated rack mounting plate 20 is mounted to the rail 17 side. A metal rack 21 is fixed to the insulating rack mounting plate 20. The first electrostatic generator 22 is electrically connected to the spray gun 12. The second static electricity generator 23 is electrically connected to the metal rack 21. Since the insulating rack mounting plate 20 is made of an insulating material, the electric charge on the metal rack 21 cannot be conducted to other components through the insulating rack mounting plate 20.
When spraying is carried out, a workpiece is installed on the rotary hanging rack 15, the driving motor 19 starts the driving chain to rotate, the driving chain drives the rotary hanging rack 15 to move along the guide rail 17 when rotating, and the spray gun 12 sprays the workpiece on the rotary hanging rack 15 until the rotary hanging rack 15 moves to a spraying position. 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 metal rack 21, the spray gun 12 and the metal rack 21 are charged with static electricity of different polarities. When the rotary hanger 15 is moved to the painting position, the metal rack 21 is engaged with the rotary hanger 15 to make the rotary hanger 15 charged with static electricity of the same polarity as the metal rack 21. That is, the rotary hanger 15 moves to the painting position with an electrostatic polarity opposite to that of the paint sprayed from the spray gun 12. When the spray gun 12 sprays, the paint can be quickly and uniformly adsorbed to the surface of the workpiece by the attraction force between the static electricity with opposite polarity, and the spraying efficiency is high and the spraying quality is good.
The 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.
In one specific embodiment, the first electrostatic generator 22 is a positive electrical generator. The second electrostatic generator 23 is a negative electric generator. Thus, the gun 12 is charged with positive static electricity, and the metal rack 21 is charged with negative static electricity.
Alternatively, the first electrostatic generator is a negative electric generator. The second electrostatic generator is a positive generator. Thus, the gun carries a negative static charge, while the metal rack carries a positive static charge.
In one embodiment, the spray coating device 10 for a workpiece further includes an electrical discharge assembly 24. The discharging assembly 24 is disposed on one side of the guide rail 17, and can be used to discharge the rotating hanger 15, so as to prevent the workpiece and the rotating hanger 15 after the spraying operation from being continuously charged with static electricity to hurt the workers.
Specifically, the discharge assembly 24 includes: a discharge block 241, a discharge chip 242, and a ground wire 243. One end of the discharging block 241 is connected to one side of the guide rail 17. The discharge piece 242 is connected to the other end of the discharge block 241. The ground lead 243 connects the discharge block 241 and the ground. When the rotary hanger 15 is driven by the driving chain to move to the position of the discharge assembly 24 and contact the discharge piece 242, the static electricity on the rotary hanger 15 is completely released by the discharge piece 242 passing through the discharge block 241 and the grounding wire 243 in sequence and grounding.
As a specific structure, the mounting bracket 11 is partitioned by a partition into a painting space and an electrostatic discharge space. The first electrostatic generator 22 and the second electrostatic generator 23 are located in the painting space. The discharge assembly 24 is located in the electrostatic discharge space.
Further, the rotary hanger 15 includes: an insulating hanger rod 151, a metal turning rod 152 and a bracket assembly 154. The metal rotating lever 152 is rotatably connected to the insulating hanger rod 151. The bracket assembly 154 is mounted on the metal pivot rod 152 and is capable of mounting a plurality of mounting workpieces.

The bracket assembly 154 is attached to the metallic rotating rod 152. The upper end of the metal rotating rod 152 is provided with a metal gear 153. When the rotary hanger 15 is moved to the painting position, the metal gear 153 is engaged with the metal rack 21 of the painting device. In the process of moving the rotary hanger 15, the metal rack 21 drives the metal gear 153 to rotate, so as to drive the metal rotating rod 152 to rotate, and further drive the bracket assembly 154 to rotate. With such a configuration, the rotary hanger 15 can be rotated, so that a plurality of workpieces can be simultaneously sprayed, and the spraying efficiency is high.
As a specific embodiment, the bracket assembly 154 includes: a plurality of metal connecting rods and a plurality of metal mounting seats 1542. One end of a plurality of metal connecting rods is connected to the metal rotating rod 152. The plurality of metal mounting seats 1542 are respectively connected to the other ends of the plurality of metal connecting rods for placing a workpiece. That is, before spraying the work pieces, the work pieces are placed on the metal mounting seats 1542, respectively. The static electricity carried on the rack is conducted to the metal mount 1542 through the metal rotating rod 152 and the metal connecting rod. Since the insulating hanging rod 151 is an insulator, static electricity on the rotary hanger 15 is not introduced to the connected components.
Further, the plurality of metal connecting rods are uniformly distributed along the circumferential direction of the metal rotating rod 152. Therefore, the distance between adjacent workpieces is equal, and the workpieces can be uniformly sprayed. Specifically, the bracket assembly 154 includes three metal connecting rods.
As a specific embodiment, the metal rotation rod 152 and the metal connection rod are provided with an insulating sleeve 1543 on the outer circumference thereof. Set up insulating sleeve 1543 and can avoid the static that carries to hinder the staff on metal dwang 152 and the metal connecting rod, also avoided simultaneously, spray gun 12 spun coating adsorbs under the electrostatic action on metal dwang 152 and the metal connecting rod. The insulating sleeve 1543 is detachably sleeved on the metal rotating rod 152 and the metal connecting rod, and is convenient to detach and clean.
As a specific embodiment, the metal mounting base 1542 is provided with an insulating shield 1544 around its periphery. The insulating shield 1544 may be mounted to the periphery of the metal mounting base 1542 by a detachable mounting method such as a screw, which can prevent the paint sprayed from the spray gun 12 from splashing around, and is convenient to detach and clean. The range of the ratio of the inner diameter of the insulating shield 1544 to the outer diameter of the mounting boss is 2 or more and 3 or less.
In one embodiment, the rotary hanger 15 includes a plurality of bracket assemblies 154. The plurality of bracket assemblies 154 are evenly distributed along the axial direction of the metallic rotating rod 152. The arrangement enables the rotary hanger 15 to mount more workpieces at one time, and the spraying efficiency can be further improved.
Further, the rotary hanger 15 further includes a connection assembly 16. The metal turning rod 152 is rotatably connected to the insulating hanger rod 151 by the connection assembly 16. Specifically, the connection assembly 16 includes: a connecting sleeve 161 and a rotational bearing 163. The upper end of the connection sleeve 161 is connected to the lower end of the insulating hanger rod 151 by a pin 164. The rotation bearing 163 is mounted to the lower end of the connection sleeve 161. The upper end of the metal rotating lever 152 passes through the rotating bearing 163. The upper end of the metal rotating rod 152 is formed with a threaded hole 1521. The threaded hole 1521 is screwed with a big head screw 165. The large head screw 165 has a large head end 1651 and a small end. The small end is screwed into the threaded hole 1521 through an external thread. The large end 1651 has an outer diameter larger than an inner diameter of the rotary bearing 163 so as to rotatably connect the metal rotating lever 152 to the rotary bearing 163, i.e., the metal rotating lever 152 can rotate relative to the rotary bearing 163. This allows the metal rotation lever 152 to rotate when the metal gear 153 rotates.
Still further, the connection assembly 16 further includes: an upper support 166, a lower support 167, and a plurality of rollers 168. A plurality of rolling members 168 are provided between the upper and lower support blades 166 and 167. The upper and lower supporting pieces 166 and 167 are fitted over the upper end of the metal rotating lever 152. The inner wall of the connection sleeve 161 is formed with an annular boss 162. The rotation bearing 163 is provided in the space surrounded by the annular boss 162. The lower side of the lower support piece 167 abuts the upper side of the annular boss 162. Such a structure can increase the stability of the rotation of the metal rotating lever 152.
Specifically, the rollers 168 are rollers.
In one embodiment, the connection assembly 16 further includes a spacer 169. Shim 169 is positioned between large head end 1651 of large head screw 165 and upper support blade 166.
