[0030] The present application is further described in detail below in conjunction with the accompanying drawings.
[0031] The present application discloses a laser engraving jig, such as Figure 1 As shown, it includes a placement base plate 1 for placing circuit boards, an upper baffle plate 4 arranged on the placement base plate 1, and two side baffle plates. The upper end surface of the placement base plate 1 is rectangular. The placement base plate 1 is provided with a strip groove 11 for facilitating picking up the circuit board. The width of the strip groove 11 is between 1 cm and 3 cm. The strip groove 11 is arranged parallel to one side edge of the placement base plate 1, and the strip groove 11 passes through the center point of the upper end surface of the placement base plate 1. The two side baffle plates are respectively arranged on both sides of the strip groove 11, and the two side baffle plates and the strip groove 11 are parallel to each other.
[0032] like Figure 1 and Figure 2 As shown, the two side baffles include a left baffle 3 and a right baffle 2. The right baffle 2 is fixedly arranged at the edge of the bottom plate 1 to limit the right side of the circuit board. In order to achieve stable clamping of circuit boards of different widths, the right baffle 2 is slidably arranged on the upper end surface of the bottom plate 1. The right baffle 2 is provided with a plurality of first bolts 31 for limiting the position of the right baffle 2. The plurality of first bolts 31 are evenly arranged along the length direction of the left baffle 3. The right baffle 2 is provided with a plurality of through holes 32 for the first bolts 31 to pass through. In order to facilitate the adjustment of the position of the right baffle 2, the through hole 32 is a strip-shaped through hole 32. The width of the strip-shaped through hole 32 is greater than the screw diameter of the first bolt 31 and smaller than the nut diameter of the first bolt 31. The length direction of the through hole 32 is parallel to the moving direction of the left baffle 3, so that after the first bolt 31 is loosened, the right baffle 2 and the first bolt 31 slide, thereby adjusting the position of the right baffle 2. One end of the first bolt 31 passes through the through hole 32 and is threadedly connected to the placement base plate 1. In order to further accurately position the moving position of the right baffle 2, the upper end surface of the placement base plate 1 is provided with a plurality of groups of threaded holes 12 for the first bolt 31 to be threadedly connected. Each group of threaded holes 12 is evenly arranged along the moving direction of the left baffle 3. By threading the first bolt 31 into different threaded holes 12, the approximate position of the left baffle 3 can be quickly adjusted.
[0033] The upper baffle 4 is arranged between the two side baffles, and the upper baffle 4 is arranged perpendicular to the side baffles. The placement base plate 1 is provided with a mounting groove 14 for mounting the upper baffle 4, and the upper baffle 4 is detachably connected to the mounting groove 14 by two second bolts. In order to meet the processing requirements of circuit boards in different situations, the placement base plate 1 is provided with a plurality of mounting grooves 14, and the plurality of mounting grooves 14 are evenly arranged along the length direction of the side baffles. By installing the upper baffle 4 in different mounting grooves 14, it is helpful to meet the processing requirements of the circuit board. In order to prevent damage to the circuit board during the installation process, the upper baffle 4 and the two side baffles are provided with a foam layer 6 on the side close to the circuit board to prevent the circuit board from being scratched.
[0034] In order to further facilitate the positioning effect of the circuit board and ensure the stability of the circuit board during the laser engraving process, a positioning pin 5 for positioning the circuit board is provided on the placement base plate 1, and a positioning hole 13 for the positioning pin 5 to be inserted is provided on the upper end surface of the placement base plate 1. The positioning hole 13 and the positioning pin 5 are detachably connected, and a fixing pin 51 is provided on the upper end surface of the positioning pin 5. By inserting the through hole 32 of the circuit board into the fixing pin 51 of the positioning pin 5, the circuit board is limited. At the same time, in order to facilitate the laser engraving requirements of different circuit boards, multiple positioning holes 13 are provided on both sides of any upper baffle 4. By inserting the positioning pin 5 into different positioning holes 13, the limiting effect of different circuit boards is achieved.
[0035] The implementation principle of this embodiment is:
[0036] When the circuit board needs to be fixed, first install the upper baffle 4 into the corresponding installation groove 14 according to the laser engraving requirements of the circuit board, insert the positioning pin 5 into the positioning hole 13 accordingly, plug the conductive hole 32 of the circuit board and the fixing pin 51 on the positioning pin 5, and at the same time, the edge positions on both sides of the circuit board are respectively abutted against the upper baffle 4 and the right baffle 2, and then adjust the position of the left baffle 3 so that the left baffle 3 abuts against the circuit board, and then fix the left baffle 3 with the first bolt 31.
