Description

Technical Field

[0001] The present application relates to the field of target drilling machines, and in particular to an automatic feeding device for a PCB target drilling machine. Background Art

[0002] Printed circuit boards (PCBs) are key components in electronic products, used to house other electronic components and connect circuits. For more complex circuit configurations, PCBs can be arranged into multiple layers and pressed together. Through-holes are created between the layers to connect the circuits on each layer, creating a multi-layer PCB. The through-holes in these multi-layer PCBs are drilled using an X-ray drilling machine. Pre-marked targets are placed at the corresponding through-hole locations on each layer to facilitate alignment. Traditionally, the PCB to be processed is manually placed on the X-ray drilling machine, where the X-ray imaging system is used to determine the location of the holes for drilling.

[0003] Patent document CN117002993A discloses a PCB drilling machine loading device.

The connecting rod 602 is L-shaped. A first gear 603 is rotatably connected above the lifting plate 501. The first gear 603 is adapted to the first rack 601. The first rack 601 will mesh with the first gear 603 and drive it to rotate during the sliding process. A screw 604 is fixedly connected above the first gear 603. The screw 604 passes through and is threadedly connected to the top of the supporting plate 301. A tooth block 605 is meshed with the front of the first gear 603. The tooth block 605 is triangular in shape. The tooth block 605 is inserted between the two teeth of the first gear 603 and is used to limit the first gear 603 when the first gear 603 is in a non-contact state with the first rack 601. The front of the tooth block 605 is fixedly connected to an elastic telescopic rod 606. The elastic telescopic rod 606 specifically includes a sleeve rod and a A spring is provided between the movable rod, the sleeve rod and the movable rod for reset. When the elastic telescopic rod 606 is compressed, it will reset under the action of the elastic force. This is the prior art.

A feeding assembly 7 for conveying materials is provided on the left side of the target drilling machine housing 2. The feeding assembly 7 includes a frame 701. A universal wheel 702 is rotatably connected to the bottom of the frame 701. A conveyor 703 is fixedly connected to the top of the frame 701. The conveyor 703 is specifically a roller conveyor 703. This is the prior art. A cleaning assembly 8 for cleaning materials is installed on the right side of the second suction cup assembly 5. A balancing assembly 9 for balancing materials during feeding is installed above the first suction cup assembly 4.

[0037] When the above-mentioned device is used, the mobile frame 701 is first used to carry the circuit board material to the feed port of the drilling machine housing 2, and then the circuit board material is transported into the drilling machine housing 2 by the conveyor 703. At this time, the circuit board material is taken by the mechanical arm 3 and aligned with the drilling target processing area in the drilling target housing 2. The mechanical arm 3 will drive the carrying plate 301 and then drive the first adsorption suction cup 402 and the second adsorption suction cup 502 to press against the circuit board material, thereby adsorbing it. Then, the mechanical arm 3 will adjust itself to align the circuit board material with the drilling target processing area. At this time, the electric push rod 507 is activated to retract and drive the piston rod 505 to slide backward in the closed tube 504. After sliding backward, the piston rod 505 will cancel the blockage of the vertical part of the closed tube 504, and the inner surface of the second adsorption suction cup 502 will be connected to the outside through the connecting pipe 503 and the closed tube 504, thereby losing the negative pressure. The adsorption of the right side of the circuit board material is released. At this time, the electric slide rail 405 drives the sliding seat 406 to slide to the right, driving the supporting piece 403 and the rotating column 404 to move to the right, and then driving the sliding plate 401 and the first adsorption suction cup 402 to move the circuit board material to the right, thereby conveying it. In this process, as the electric push rod 507 contracts, it will also drive the first rack 601 to slide backward. During the backward sliding process, the first rack 601 will mesh with the first gear 603 and drive it to rotate. The rotation of the first gear 603 will drive the screw 604 to rotate. When the screw 604 rotates, it will drive the lifting plate 501 to rise under the limiting action of the limiting rod 607. The rise of the lifting plate 501 will drive the second adsorption suction cup 502 to rise, thereby preventing the material from being scratched by the second adsorption suction cup 502 when the first adsorption suction cup 402 pushes the circuit board material to move to the right.

[0038] Example 2, see Figures 1-8The cleaning component 8 includes a protective shell 801. The protective shell 801 is in the shape of an elongated rectangular parallelepiped with a hollow interior and is opened up and down. A support rod 802 is fixedly connected to the right side of the protective shell 801. There are two support rods 802. The support rod 802 is fixedly connected to the right side of the carrier plate 301. The support rod 802 is in a C-shape. A brush 803 is slidably connected to the inner surface of the protective shell 801. The bristles of the brush 803 are arranged below it. A hydraulic pipe 804 is passed through and fixedly connected to the top of the protective shell 801. The hydraulic pipe 804 is in a U-shaped shape. Liquid is arranged in the hydraulic pipe 804. The surface is slidably connected with a first hydraulic rod 805 and a second hydraulic rod 806. The first hydraulic rod 805 and the second hydraulic rod 806 are slidably connected to the inner surface of the hydraulic tube 804 through a piston. The first hydraulic rod 805 is fixedly connected to the top of the lifting plate 501, and the second hydraulic rod 806 is fixedly connected to the top of the brush 803. A limiting telescopic rod 807 is fixedly connected to the top of the brush 803. There are two limiting telescopic rods 807. The limiting telescopic rod 807 is specifically an ordinary telescopic rod, which is used to limit the brush 803 when it is raised or lowered.

[0039] When the above-mentioned equipment is used, when the lifting plate 501 rises, it will drive the first hydraulic rod 805 to slide upward in the hydraulic tube 804. At this time, the first hydraulic rod 805 will push the liquid in the hydraulic tube 804, and then push the second hydraulic rod 806, so that the second hydraulic rod 806 slides in the hydraulic tube 804. At this time, the second hydraulic rod 806 will slide down in the hydraulic tube 804, and the second hydraulic rod 806 will push the brush 803 to slide downward in the protective shell 801. When the brush 803 descends, the bristles at the lower end of the brush will extend downward from the protective shell 801, thereby contacting the circuit board material. At this time, when the circuit board material is pushed to the right by the first adsorption suction cup 402, the upper surface of the circuit board material will be cleaned by the brush 803, thereby facilitating the cleaning of floating dust on the upper surface of the circuit board material.

[0040] Example 3, see Figures 1-8The balancing assembly 9 includes a second hydraulic chamber 901, in which liquid is provided. The second hydraulic chamber 901 is fixedly connected to the outer surface of the sliding seat 406. The inner surface of the second hydraulic chamber 901 is slidably connected to a fourth hydraulic rod 902.

The outer surface of the fourth hydraulic rod 902 is slidably connected to a shaft bracket 903. The shaft bracket 903 includes a shaft sleeve and a connecting rod for limiting the position of the fourth hydraulic rod 902 when it is raised or lowered. The shaft bracket 903 is fixedly connected to the outer surface of the sliding seat 406. The second rack 9 is fixedly connected below the fourth hydraulic rod 902. 04, a second gear 905 is engaged with the right side of the second rack 904, and the second gear 905 is fixedly connected to the outer surface of the rotating column 404. The balancing assembly 9 also includes a first hydraulic tank 906, which is fixedly connected to the rear of the supporting plate 301. The first hydraulic tank 906 and the second hydraulic tank 901 are connected by a pipeline, and the first hydraulic tank 906 and the second hydraulic tank 901 are connected and communicated through a hose. The inner surface of the first hydraulic tank 906 is slidably connected to a third hydraulic rod 907, and the third hydraulic rod 907 is slidably connected to the first hydraulic tank 906 through a piston, and the third hydraulic rod 907 is fixedly connected to the top of the brush 803.

[0041] When the above-mentioned equipment is used, when the second adsorption suction cup 502 loses the negative pressure and releases the adsorption of the right side of the circuit board material, the circuit board material will tilt slightly to the right under the action of gravity, causing the first adsorption suction cup 402 to deform to a certain extent. At this time, as the brush 803 descends, it will pull the third hydraulic rod 907 to slide downward on the inner surface of the first hydraulic chamber 906. At this time, the third hydraulic rod 907 will extract the liquid in the second hydraulic chamber 901 through the hose, causing the fourth hydraulic rod 902 to slide down in the second hydraulic chamber 901. The descent of the fourth hydraulic rod 902 will drive the second rack 904 to descend. The descent of the second rack 904 will drive the second gear 905 to make the rotating column 404 rotate a certain angle on the sliding seat 406. At this time, the rotating column 404 will drive the supporting piece 403 to make the sliding plate 401 deflect to the right by a certain angle, thereby driving the first adsorption suction cup 402 to make the circuit board material drooping to the right flat again, so as to facilitate accurate material feeding.
