specific Embodiment 1

[0028] Specific embodiment 1, according to figure 1 , image 3 and Figure 4 As shown, a laser processing device for PCB boards includes a base 1, a laser generator 22, and a laser gun 23. The base 1 is threadedly connected with a screw 7, and the base 1 supports the screw 7 for rotational movement, and one end of the screw 7 is rotationally connected There is a splint 4, and the screw 7 changes the rotary motion into a linear motion under the conversion of the base 1, and drives the splint 4 to translate. A support seat 9 is installed above the base 1, and the support seat 9 works under the support of the base 1. The support seat 9 is provided with a first reduction motor 12 inside, and the support seat 9 supports the work of the first reduction motor 12, and a connecting rod 13 is connected to the bottom of the first reduction motor 12, and the first reduction motor 12 drives the connecting rod 13 to move, and the first reduction motor 12 Under the non-working state, the c...

specific Embodiment 2

[0029] Specific embodiment 2, with reference to figure 1 and figure 2 , on the basis of specific embodiment 1, screw rod 7 and splint 4 are provided with two groups, conveniently control the fixed position of PCB board, base 1 is processed with chute 2, the surface of splint 4 contacts with the surface of chute 2 smoothly, reduces The wear of the splint 4, at the same time, restricts the movement direction of the splint 4, so that the splint 4 can better maintain the linear motion. The base 1 is processed with a guide groove 3, and the end of the splint 4 is equipped with a guide block 6, and the movement direction of the splint 4 is controlled by the guide block. 6, and the guide block 6 is in point contact with the surface of the guide groove 3, the movement resistance of the guide block 6 is small, the guide block 6 makes the splint 4 move linearly more stably, and the splint 4 is processed with a concave hole for the end of the screw rod 7 Groove 5, at least two pillars ...

specific Embodiment 3

[0030] Specific embodiment 3, with reference to figure 1 and image 3, On the basis of the specific embodiment 1, the support seat 9 is processed with a window 10 for the movement guidance of the connecting rod 13, a part of the connecting rod 13 moves in the window 10, the first reduction motor 12 is embedded in the sliding seat 11, the second A deceleration motor 12 moves with the sliding seat 11, the connecting rod 13 is in clearance fit with the sliding seat 11, the sliding seat 11 is located in the inner cavity of the supporting seat 9, the sliding seat 11 moves in the supporting seat 9, and the sliding seat 11 is set There are a plurality of balls 14, the balls 14 are located below the first reduction motor 12 and the second reduction motor 15, and the longitudinal distribution of the balls 14 is in point contact with the side of the toothed plate 17, reducing the movement resistance of the sliding seat 11, while ensuring that both A toothed plate 17 can limit the direc...

Abstract

The invention relates to a laser processing device for a PCB. The laser processing device comprises a base, a laser generator and a laser gun; a screw is connected to the base in a threaded mode, anda clamping plate is rotatably connected to one end of the screw; a supporting seat is installed above the base, a first gear motor is arranged inside the supporting seat, a connecting rod is rotatablyconnected below the first gear motor, a first driving device is installed at the lower end of the connecting rod, a first swing rod is rotatably connected with the first driving device, and a seconddriving device is installed at the lower end of the first swing rod; the second driving device is rotatably connected with a second swing rod, and the laser generator and the laser gun are installed at the lower end of the second swing rod; and the first gear motor, the second gear motor, the first driving device, the second driving device, the laser generator and the laser gun are connected witha control unit by wires. By arranging the first gear motor, the first driving device and the second driving device, the position height of the laser generator and the laser gun can be adjusted, and precise positioning is realized and punching can be carried out.

Description

technical field [0001] The invention relates to a laser processing device for PCB boards, belonging to the technical field of processing and punching equipment for PCB boards. Background technique [0002] The PCB circuit board is the printed circuit board, which is the provider of the electrical connection of electronic components. Its development has a history of more than 100 years, and the main part of its design is layout design. The main advantage of using circuit boards is to greatly reduce the errors of wiring and assembly, and improve the level of automation and production labor rate. According to the number of layers of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards. Since the printed circuit board is not a general terminal product, the definition of the name is slightly confusing. The motherboard used for personal computers is called the motherboard, not th...
