[0045] The transmission assembly 101 comprises a positioning plate 1011, a positioning frame 1012, a transmission servo motor 1013, an adjusting ring 1014, an adjusting gear 1015 and an adjusting servo motor 1016. The positioning frame 1012 is bolted to the left side of the positioning plate 1011. The transmission servo motor 1013 is bolted to the front side of the positioning frame 1012. The adjusting ring 1014 is bolted to the left side of the positioning frame 1012. The adjusting gear 1015 is rotatably connected to the bottom of the inner side of the adjusting ring 1014. The adjusting servo motor 1016 is bolted to the left side of the bottom of the adjusting ring 1014. The left side of the adjusting gear 1015 is bolted to the output end of the right side of the adjusting servo motor 1016. The conveyor belt group 3 is bolted to the top and bottom of the positioning frame 1012, respectively. By arranging the transmission assembly 101, the positioning plate 1011 can be limited with the positioning frame 1012, the transmission servo motor 1013, the adjusting ring 1014, the adjusting gear 1015 and the adjusting servo motor 1016. The positioning plate 1011 can allow the positioning frame 1012 to support and limit the conveyor belt group 3. The transmission servo motor 1013 can drive the positioning assembly 102 to rotate, so that the positioning assembly 102 can drive the printed circuit board to move. The adjusting servo motor 1016 drives the adjusting gear 1015 to rotate, and the adjusting gear 1015 can drive the adjusting assembly 201 in the adjusting ring 1014 to rotate, so as to change the angle of the adjusting assembly 201.

[0046] The positioning assembly 102 comprises a transmission rotating drum 1021, an adsorption hole groove 1022 and a suction pump 1023. The transmission rotating drum 1021 is rotatably connected to the inner side of the positioning frame 1012. The adsorption hole groove 1022 is arranged on the surface of the transmission rotating drum 1021. The suction pump 1023 is communicated with the rear side of the transmission rotating drum 1021. The surface of the suction pump 1023 is rotatably connected to the rear side of the inner side of the positioning frame 1012. The front side of the transmission rotating drum 1021 is bolted to the output end of the rear side of the transmission servo motor 1013. By arranging the positioning assembly 102, the transmission rotating drum 1021 can cooperate with the adsorption hole groove 1022 and the suction pump 1023. When the suction pump 1023 removes the air in the adsorption hole groove 1022 to limit the printed circuit board, the transmission rotating drum 1021 drives the printed circuit board adsorbed in the adsorption hole groove 1022 to move, so as to move the printed circuit board to the machining mechanism for drilling machining, and the debris generated during machining can be adsorbed.

[0047] The intercepting assembly 103 comprises a guide ring rail 1031, an arc pulley set 1032 and a gravity block 1033. The guide ring rail 1031 is bolted to the inner side of the transmission drum 1021. The arc pulley set 1032 is slidingly connected to the inner side of the guide ring rail 1031. The gravity block 1033 is bolted to the top of the arc pulley set 1032. By arranging the intercepting assembly 103, the guide ring rail 1031 can cooperate with the arc pulley set 1032 and the gravity block 1033. The movement of the arc pulley set 1032 is guided and limited by the guide ring rail 1031. Therefore, the gravity block 1033 can always keep the arc pulley set 1032 vertical to the ground due to its gravity. Thus, the bottom adsorption hole groove 1022 can be closed, and the negative pressure of the bottom adsorption hole groove 1022 can be prevented. Therefore, the printed circuit board after processing can fall to the conveyor belt set 3.

[0048] The working principle of the embodiment is as follows. First, the conveying mechanism 1 and the conveyor belt set 3 are powered on and started. Then, the printed circuit board to be processed is placed on the top of the conveyor belt set 3. Then, the conveyor belt set 3 on the top drives the printed circuit board to move to the adsorption hole groove 1022. Then, the air in the transmission drum 1021 is extracted by the air pump 1023. The adsorption hole groove 1022 can adsorb the printed circuit board due to the negative pressure generated by the extracted air. Then, the transmission drum 1021 rotates along the transmission servo motor 1013 until the printed circuit board moves to the desired processing position. Then, the adjusting gear 1015 drives the adjusting servo motor 1016 to adjust the angle of the adjusting mechanism 2 in the adjusting ring 1014 until it moves to the desired drilling position. Then, the adjusting mechanism 2 drills the printed circuit board. When the drilling produces debris, the debris is adsorbed by the adsorption hole groove 1022 and stored in the transmission drum 1021. After the drilling of the printed circuit board is completed, the transmission drum 1021 drives the printed circuit board in the adsorption hole groove 1022 to move to the bottom conveyor belt set 3. When the printed circuit board approaches the bottom conveyor belt set 3, the arc pulley set 1032 moves along the guide ring rail 1031 and keeps vertical to the gravity direction in the transmission drum 1021, and blocks the adsorption hole groove 1022. When the adsorption hole groove 1022 is blocked, the printed circuit board falls to the bottom conveyor belt set 3 and is taken away.
