[0023] Please refer to Figures 1-2As shown, this illustrates the specific structure of a preferred first embodiment of the present invention, which is an automatic through-hole machine for circuit boards. It includes a machine body 10 and a conveying assembly 20 and a feeding assembly 30 disposed on the machine body 10. During material feeding, the traction part 31 in the feeding assembly 30 drives the circuit board on the receiving end 32 of the feeding assembly 30 to move below the conveying part 21 in the conveying assembly 20. As the conveying part 21 rotates, a circuit board moves into the traction groove 22 on the conveying assembly 20, and then moves above the processing part 11 on the machine body 10. Compared to existing automatic through-hole machines for circuit boards, where two circuit boards are easily stacked during conveying, this automatic through-hole machine for circuit boards, through the cooperation of the traction part 31 and the conveying part 21, allows multiple circuit boards stacked on the receiving end 32 of the feeding assembly 30 to enter the traction groove 22 one by one, thus ensuring the accuracy and efficiency of circuit board processing.

[0024] Specifically, when drilling holes in a circuit board, multiple stacked circuit boards are placed on the receiving end 32 of the feeding assembly 30. Driven by the traction unit 31, the receiving end 32 moves closer to the conveying unit 21 until the side wall of the top circuit board in the stacked circuit boards on the receiving end 32 contacts the conveying unit 21. The circuit board is pushed into the traction groove 22 by the rotation of the conveying unit 21. Then, the circuit board can be moved in the traction groove 22 by the mutual squeezing between the circuit boards until it moves to the bottom of the processing unit 11. The circuit board is drilled by the insertion of the ejector pin on the processing unit 11.

[0025] like Figure 1 As shown, exemplarily, the conveying assembly 20 includes a guide plate 23 that slides on the body 10 and is located beside the conveying section 21. The guide plate 23 includes a U-shaped sleeve 232 fitted onto a bracket in the body 10, and a guide bar 233 connected to the sleeve 232, the guide bar 233 being located beside the traction section 31. When the circuit board moves below the conveying section 21, the guide bar 233 is moved to contact the sidewall of the circuit board to be conveyed, ensuring that the conveyed circuit board does not shift under the push of the conveying section 21 and smoothly enters the traction groove 22.

[0026] like Figure 1 As shown, exemplarily, the feeding assembly 30 also includes a placement plate 33 that slides on the machine body 10 for placing circuit boards. The placement plate 33 is located below the conveying section 21 and the guide plate 23, and the receiving end 32 is the upper surface of the placement plate 33. The stacked circuit boards are placed on the placement plate 33, which is horizontally positioned and located below the conveying section 21. After the placement plate 33 is driven by the traction section 31 to move towards the conveying section 21, the circuit boards are in a horizontal state when pushed by the conveying section 21 to avoid the circuit boards tilting and affecting their insertion into the traction groove 22.

[0027] like Figure 1As shown, the opposite side of the guide plate 23 and the receiving end 32 is provided with a row of rod bodies 231, and when the placing plate 33 approaches the guide plate 23, the rod bodies 231 pass through the placing plate 33 and contact the side walls of the circuit boards on the placing plate 33. When the placing plate 33 approaches the conveying part 21, the contact between the rod bodies 231 and the top end of the placing plate 33 and the contact between the rod bodies 231 and the side walls of the circuit boards on the placing plate 33 can effectively prevent the circuit boards in the stack from moving when they are pressed by the conveying part 21, so that the other circuit boards are not offset, and the other circuit boards are not affected when entering the traction groove 22.

[0028] As shown in Figure 1 As shown, the placing plate 33 is provided with a row of through holes 331 corresponding to the rod bodies 231, and when the placing plate 33 contacts the rod bodies 231, the rod bodies 231 pass through the through holes 331. By providing the through holes 331 on the placing plate 33, the rod bodies 231 can pass through the through holes 331, so that the rod bodies 231 do not affect the approach of the placing plate 33 to the conveying part 21.

[0029] As shown in Figure 1 As shown, the conveying part 21 includes a driving motor 211 mounted on the body 10 and a rotating sleeve 212 provided at the output end of the driving motor 211, and the side wall of the rotating sleeve 212 is provided with at least two pushers 213 at equal intervals. With the driving of the driving motor 211, the output shaft of the driving motor 211 drives the rotating sleeve 212 to rotate, so that the pushers 213 arranged at equal intervals on the rotating sleeve 212 contact the circuit boards on the placing plate 33 and push the circuit boards on the placing plate 33 one by one into the traction groove 22.

[0030] The pushers 213 are made of soft rubber or plastic. The use of soft rubber and plastic can avoid accidental damage when pushing the circuit boards, and increase the friction between the pushers 213 and the circuit boards.

[0031] As shown in Figure 1 As shown, the conveying assembly 20 further includes a containing groove 24 provided on the two opposite side walls of the body 10, and one side of the placing plate 33 is inserted into the containing groove 24.

[0032] The inner cavity of the containing groove 24 is provided with a positioning rod 241 passing through the placing plate 33, and the side of the placing plate 33 away from the positioning rod 241 is connected to the output end of the traction part 31 inserted into the containing groove 24.

[0033] The traction part 31 is an electric push rod. In order to save cost, the traction part 31 for driving the placing plate 33 only contains one, and the traction part 31 is an electric push rod and is fixed at the top end of the machine body 10. With the upward movement of the traction part 31, the placing plate 33 moves towards the push piece 213, and vice versa. The placing plate 33 moves away from the push piece 213, away from the placing plate 33 for placing the stacked circuit board to the plate surface, and moves towards each other for pushing the stacked circuit board into the traction groove 22 one by one, and processing through the processing part 11. The accommodating grooves 24 opened on both sides of the machine body 10 and the positioning rod 241 fixed in one of the accommodating grooves 24 are used for guiding the movement of the placing plate 33, avoiding the inclination of the placing plate 33 when moving up and down, and affecting the circuit board placed by the placing plate 33 to keep horizontal.

[0034] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application. Any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical scheme of the present application.
