[0002] As we all know, the equipment used for printed circuit board processing usually combines multiple technologies such as mechanics, electronics and chemistry. Its working principle is to first transport the printed circuit board to be processed to a specific processing area through a conveying mechanism, and then use precision drilling equipment to perform drilling operations at designated locations. The required holes are accurately drilled on the board through a high-speed rotating drill bit. Then, electroplating and other processes are used to treat the surface of the circuit board to enhance conductivity. At the same time, an optical detection system is used to monitor the processing process in real time to ensure processing accuracy. Finally, after a series of processing steps, high-quality printed circuit board products are output.

Between the plugging process of the semi-open window via processing and the solder mask process of the silk screen board surface, the plugging ink of the printed circuit board is dried in an automated manner to avoid ink overflow caused by post-baking after development and affecting the solder mask area, and the intersecting window area is automatically ground to remove ink to ensure the quality of the solder mask.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0030] See also Figure 1-5A printed circuit board processing device includes a conveying mechanism 1 and a conveyor belt group 3. The conveyor belt group 3 is bolted to the top and bottom of the conveying component 1. The conveying mechanism 1 includes a transmission component 101, a positioning component 102 and an interception component 103. The positioning component 102 rotates the inner side of the transmission component 101. The interception component 103 is arranged on the inner side of the positioning component 102. The conveying mechanism 1 can cooperate with the conveyor belt group 3 by setting the transmission component 101. The transmission component 101 can cooperate with the positioning component 102 and the interception component 103. The positioning component 102 is driven to rotate by the transmission component 101. When the conveyor belt group 3 moves the printed circuit board to the positioning component 102, When the positioning component 102 limits the position of the printed circuit board, the position of the positioning component 102 is moved, so that the position of the positioning component 102 can be moved to the position required for processing by the adjusting mechanism 2, and the debris generated during the processing can be collected. After the adjusting mechanism 2 completes the processing of the printed circuit board, when the adjusting mechanism 2 moves the printed circuit board to the conveyor belt group 3 at the bottom, the intercepting component 103 can always maintain a position perpendicular to the direction of gravity, so that the positioning component 102 moved to the bottom conveyor belt group 3 can be blocked, so that the bottom of the positioning component 102 can lose its adsorption force, allowing the printed circuit board to fall to the conveyor belt group 3.

[0031] Among them, the transmission component 101 includes a positioning plate 1011, a positioning frame 1012, a transmission servo motor 1013, an adjustment ring 1014, an adjustment gear 1015 and an adjustment servo motor 1016.

The adjustment servo motor 1016 drives the adjustment gear 1015 to rotate, and the adjustment gear 1015 can drive the adjustment component 201 in the adjustment ring 1014 to rotate, so that the angle of the adjustment component 201 can be changed.

The transmission drum 1021 rotates along with the adjustment of the servo motor 1016. When the vacuum pump 1023 extracts the air in the adsorption hole groove 1022 to limit the printed circuit board, the printed circuit board adsorbed in the adsorption hole groove 1022 is driven to move together, so that the printed circuit board can be moved to the processing mechanism for drilling processing, and the debris generated during the processing can be adsorbed.

[0033] Among them, the interception component 103 includes a guide ring rail 1031, a curved pulley group 1032 and a gravity block 1033.

The adjusting mechanism 2 will perform drilling processing on the printed circuit board. When debris is generated during the drilling processing, the debris will be adsorbed into the transmission drum 1021 through the adsorption hole groove 1022 for storage until the drilling processing of the printed circuit board is completed. The transmission drum 1021 will drive the printed circuit board in the adsorption hole groove 1022 to move toward the conveyor belt group 3 at the bottom. When the printed circuit board is close to the conveyor belt group 3 at the bottom, the arc pulley group 1032 will move along the guide ring rail 1031 and driven by the gravity block 1033 in the transmission drum 1021 at a position perpendicular to the direction of gravity, and block the adsorption hole groove 1022 that passes through. When the adsorption hole groove 1022 is blocked, the printed circuit board will fall to the conveyor belt group 3 at the bottom and be taken away. Example
