Abstract
The utility model discloses a jig for improving the surface flatness of laser drilling. The jig is a thinner metal sheet, wherein the surface of the metal sheet is flat; the length and width of the metal sheet are consistent with the size of the processing table top of a board; the metal sheet is arranged between a board top and a to-be-processed material; the metal sheet is designed with a rectangular hole array; the pore diameter of the rectangular hole array is designed to be consistent with the pore diameters of suction holes in the board top; the central distances of horizontal holes are consistent with those of horizontal holes in the board top; and the central distances of vertical holes are twice those of the vertical holes in the table top. The jig for improving the surface flatness of laser drilling is simple in structure, unevenness of the table top caused by punching onto the board top by laser after a medium layer is broken down by the laser can be effectively prevented under the situation of not increasing the cost, the surface flatness of laser drilling can be effectively improved, and the reject ratios of laser-processed products are effectively reduced.
Description
Technical field
The utility model relates to laser drill processing, is specifically related to a kind of tool that improves the laser drill surface smoothness.
Background technology
To the light energy absorbability, strong material carries out laser drill and adds man-hour, laser can puncture dielectric layer and get on machine table top, cause table top uneven, at present, the industry Main is a metal fixture of pad between machine table top and processing materials, because metal can be reflective, a little less than the light energy absorbability, thereby make laser can not arrive machine table top.But, the shortcoming of this technology is the air entry that this metal fixture has blocked machine table top, make material can't entirely be adsorbed in metal plate, when the material air spots can cause laser drill, machine can't accurately capture alignment target, causes the boring skew or affects the laser drill effect.
Summary of the invention
The problem that the utility model need solve is to provide a kind of simple in structure, can effectively avoid laser breakdown material decorated fire machine table top, effectively improve the laser drill surface smoothness, guarantee the tool of the raising laser drill surface smoothness of the precision of laser drill and hole crudy.
To achieve these goals, the utility model is designed a kind of tool that improves the laser drill surface smoothness, it is a thinner metallic plate, metallic plate is placed between machine table top and processing materials, be designed with the rectangular opening battle array on metallic plate, the pore size of rectangular opening battle array is designed to consistent with machine table top suction hole pore size, and horizontal direction hole center distance is consistent with machine table top horizontal direction hole center distance, and vertical direction hole center distance is the OC twice in machine table top vertical direction hole.
The surfacing of described metallic plate, length and width size and board processing table top consistent size.
The utility model improves the beneficial effect of the tool of laser drill surface smoothness: design rectangular opening battle array on metallic plate, the pore size of rectangular opening battle array is consistent with the machine table top pore size, horizontal direction hole center distance is consistent with machine table top horizontal direction hole center distance, and vertical direction hole center distance is the OC twice in machine table top vertical direction hole.This design can be avoided laser breakdown material decorated fire machine table top, be beneficial to suction hole tool entirely is adsorbed in to the board surface, and then make processing materials entirely be adsorbed on metal plate, that is to say and make processing materials entirely be adsorbed on machine table top all the time, guarantee the precision of laser drill and the quality of hole processing, effectively avoid the bad appearance of product, improved operating efficiency.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model improves the tool of laser drill surface smoothness.
The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with specific embodiment and accompanying drawing, structural principle of the present utility model is described in further detail.
[0009]as shown in Figure 1, a kind of tool that improves the laser drill surface smoothness, it is a thinner metallic plate 1, metallic plate 1 is placed between machine table top and processing materials, the surfacing of metallic plate 1, length and width size and board processing table top consistent size, be designed with rectangular opening battle array 2 on metallic plate 1, the pore size of rectangular opening battle array 2 is designed to consistent with machine table top suction hole pore size, horizontal direction hole center distance is consistent with machine table top horizontal direction hole center distance, vertical direction hole center distance is the OC twice in machine table top vertical direction hole, this design can be avoided laser breakdown material decorated fire machine table top, be beneficial to suction hole tool entirely is adsorbed in to the board surface, and then make processing materials entirely be adsorbed on metal plate, that is to say and make processing materials entirely be adsorbed on machine table top all the time, guarantee the precision of laser drill and the quality of hole processing, effectively avoided the bad appearance of product, improved operating efficiency.
[0010]the above-mentioned specific embodiment is preferred embodiment of the present utility model; can not be limited with the utility model; other any change that does not deviate from the technical solution of the utility model and make or other equivalent substitute modes, within all being included in protection domain of the present utility model.
Claims (2)
