Detailed implementation manner

[0021] As Figures 1 to 5 shown, the automatic PCB board surface cleaning sticky dust machine includes a rubber-coated wheel 1. Moving blocks 2 are arranged on the outer sides of both ends of the rubber-coated wheel 1. The rubber-coated wheel 1 is rotatably connected inside the moving blocks 2. A plurality of sliding rods 3 are fixedly installed inside the moving blocks 2. Mounting blocks 4 are arranged below each moving block 2. Round holes 5 corresponding in number to the sliding rods 3 are formed inside the mounting blocks 4. The sliding rods 3 and the mounting blocks 4 are slidably matched through the round holes 5; the moving blocks 2 and the mounting blocks 4 are connected by compression springs 6.

[0022] A loading mechanism 13 is arranged below the two rubber-coated wheels 1. The loading mechanism 13 here mainly consists of a conveyor belt, conveyor rollers and a motor, which is prior art and will not be elaborated here too much. It is used to convey the PCB board and convey the PCB board into the equipment for surface dust removal. The loading mechanism 13 is installed on the sticky dust machine housing 12.

[0023] During specific operation, when the PCB board is conveyed into the equipment, since there is a gap between the rubber-coated wheel 1 and the loading mechanism 13, that is, the loading mechanism 13 is used to convey the PCB board below the rubber-coated wheel 1. At this time, the rubber-coated wheel 1 can be used to adhere dust on the surface of the PCB board. At the same time, the PCB board can also pass smoothly below the rubber-coated wheel 1 when the thickness of the PCB board changes. When the PCB board passes through the bottom of the rubber-coated wheel 1, it can squeeze the rubber-coated wheel 1 to move upward against the action of the compression spring 6. At the same time, the rubber-coated wheel 1 always fits with the surface of the PCB board. The setting of the sliding rods 3 and the round holes 5 can enable the moving blocks 2 to move up and down stably. This structure is beneficial for surface sticky dust work on PCB boards of different models, and there is no need to manually adjust the distance between the rubber-coated wheel 1 and the loading mechanism 13 to adapt to the thickness of the PCB board when the PCB board model changes.

[0024] As Figures 3 to 5 shown, the number of the rubber-coated wheels 1 is set to two, and both rubber-coated wheels 1 are rotatably matched with the moving blocks 2; A liftable sticky dust paper roll 7 is arranged above the two rubber-coated wheels 1; Sliders 8 are arranged at both ends of the sticky dust paper roll 7. The sticky dust paper roll 7 is rotatably matched with the sliders 8. An electric push rod 9 is arranged above the sliders 8, and the output end of the electric push rod 9 is fixedly connected to the sliders 8.

[0025] Two support plates 10 are symmetrically and fixedly installed at the top of the dust sticking machine housing 12. The two support plates 10 are fixed by a connecting rod. The electric push rod 9 is fixedly installed on one side of the support plate 10. A chute is formed inside the support plate 10. One end of the slider 8 is arranged in the chute and is slidably matched with it. The mounting block 4 is fixedly connected to one side of the support plate 10.

[0026] During specific operation, in order to further remove the adhered dust on the rubber-coated wheel 1 and better remove dust from the PCB board, the electric push rod 9 is started to drive the slider 8 to move downward. When the slider 8 moves downward, it drives the dust sticking paper roll 7 to move towards the rubber-coated wheel 1. The dust sticking paper roll 7 is positioned between the two rubber-coated wheels 1, so that when the dust sticking paper roll 7 moves downward, it can just fit onto the surfaces of the two rubber-coated wheels 1 below it, thereby sticking the dust on the surface of the rubber-coated wheel 1 clean, facilitating the continuous dust sticking of the rubber-coated wheel 1 on the surface of the PCB board. When the dust sticking paper roll 7 presses down, the compression spring 6 jacks up the rubber-coated wheel 1. At this time, the setting of the compression spring 6 can play a buffering and hard limit role.

[0027] As Figure 1 shown, a protective cover 14 is arranged outside the two support plates 10 to prevent dust from entering the equipment.

[0028] As Figure 2 shown, an electrostatic eliminator 11 is fixedly installed on the connecting rod. The electrostatic eliminator 11 can generate a large number of air masses with positive and negative charges to neutralize the charges on the objects passing through its ion radiation area. When the surface of an object is negatively charged, it will attract the positive charges in the radiation area. When the surface of an object is positively charged, it will attract the negative charges in the radiation area, thereby neutralizing the static electricity on the surface of the object and achieving the purpose of eliminating static electricity.
