Description
Technical Field
The invention relates to the technical field of laser etching of Z-shaped parts, in particular to a method for efficiently improving the laser etching efficiency of a product.
Background
The structure of the Z-shaped part is shown in figure 1, and comprises a top plate (1), a bottom plate (2) and a connecting plate (3) butted between the top plate (1) and the bottom plate (2), wherein the height h between the top surface of the top plate (1) and the top surface of the bottom plate (2) is 2mm, and laser engraving treatment is required to be carried out on the top surface of the top plate (1) and the top surface of the bottom plate (2) in the process. The existing laser engraving process of Z-shaped parts is to arrange the Z-shaped parts in a carrying disc; placing the carrying disc on a laser etching table of a laser etching machine; an operator moves a laser engraving head of the laser engraving machine to be right above a top plate (1) of the Z-shaped part; adjusting a laser etching head of the laser etching machine to enable a laser etching condensation point to focus on the top surface of the top plate (1); opening the laser engraving machine, and performing laser engraving on the top surface of the top plate (1) by using laser beams emitted by the laser engraving head, so that the laser engraving on the top surface of the top plate (1) is realized; after roof (1) radium carving, operating personnel remove radium carving head behind the bottom plate (2) of Z shape part directly over, and radium carving head can't carry out radium carving to the top surface of bottom plate (2), its leading cause is that radium carving range of radium carving head is for the height in 0~1mm scope above the radium carving focal point, and for the height in 0~1mm scope below the radium carving focal point as shown in figure 2, and because roof (1) top surface apart from bottom plate (2) top surface height h be 2mm, even after removing radium carving head to the top surface of bottom plate (2), also can't carry out radium carving to the top surface of bottom plate (2). In order to realize carrying out radium carving to bottom plate (2), need readjust radium carving head and make its radium carving focus on the top surface of bottom plate (2), open radium carving machine once more, can carry out radium carving to the top surface of bottom plate (2) to finally realize the radium carving to Z shape part. However, this kind of radium carving mode is though the top surface of roof (1) and bottom plate (2) that can radium carving Z shape part, but when carrying out radium carving bottom plate (2), needs the radium carving focal point of radium carving head of second adjustment, and the quantity of the Z shape part of splendid attire on the year dish is very much, when every radium carving a part, all need adjust radium carving focal point of radium carving head, this has reduced radium carving efficiency undoubtedly, and then has reduced the production efficiency of Z shape part.

Detailed Description
The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:
as shown in fig. 3, a method for efficiently improving laser etching efficiency of a product includes the following steps:
s1, respectively placing a Z-shaped part to be laser etched in each accommodating groove of the carrying disc, and placing the carrying disc on the table top of a laser etching table of the laser etching machine; the distance between two adjacent accommodating grooves is equal;
s2, moving the position of the laser carving head 4 of the laser carving machine on the horizontal plane, enabling the laser carving head 4 to move right above the top plate 1 of any part in the first row of Z-shaped parts, adjusting the laser carving head 4 to enable laser carving light-gathering points of the laser carving head to be gathered on the top surface of the top plate 1 of the part, measuring the height between the laser carving light-gathering points and the laser carving head 4, and recording the height as h 1;
s3, moving the laser engraving machine on the horizontal plane to enable the laser engraving head 4 to move to the position right above the bottom plate 2 of the part in the step S2, adjusting the laser engraving head 4 to enable laser engraving light-gathering points of the laser engraving head 4 to be gathered on the top surface of the bottom plate 2, measuring the height between the laser engraving light-gathering points and the laser engraving head 4, and recording the height as h 3;
s4, adding the value of h1 and the value of h3, and dividing the total value by 2 to obtain h2, wherein h2 is the height between the midpoint of the distance from the top surface of the top plate 1 to the top surface of the bottom plate 2 and the laser carving head 4;
s5, adjusting the position of a laser etching condensation point of the laser etching head 4 to enable the height between the laser etching condensation point and the laser etching head 4 to be h 3;
s6, moving the laser engraving head 4 to a position right above the top plate 1 of the first part of the first row of Z-shaped parts, opening the laser engraving machine, and performing laser engraving on the top surface of the top plate 1 of the first part by using the laser engraving head 4; after laser etching, moving the laser etching head 4 right above the bottom plate 2 of the first part, and performing laser etching on the top surface of the bottom plate 2 by the laser etching head 4, so that laser etching on the first Z-shaped part is realized;
s7, moving the laser etching head 4 right above a top plate of the second part, repeating S6 to perform laser etching on the second part, repeating S6-S7 for multiple times, and performing laser etching on all parts in the first row of Z-shaped parts. And repeating the step S7 for multiple times to perform laser etching on all Z-shaped parts on the carrying disc.
In the steps S5-S6, because the laser etching condensation point of the laser etching head 4 is just at the middle point of the distance from the top surface of the top plate 1 to the top surface of the bottom plate 2, when the laser etching head 4 moves right above the top plate 1, because the laser etching range of the laser etching head 4 is the height which is 0-1 mm above the laser etching condensation point, the laser beam of the laser etching head 4 just performs laser etching on the top surface of the top plate 1; when the laser etching head 4 moves to the bottom plate 2, because the laser etching range of the laser etching head 4 is relative to the height of the laser etching focus within the range of 0-1 mm below the laser etching focus, the laser beam of the laser etching head 4 just performs laser etching on the top surface of the bottom plate 2. Therefore, the laser etching method can be used for carrying out laser etching on all parts on the carrying disc only by adjusting the position of the laser etching light-gathering point once, and compared with the traditional method that the laser etching light-gathering point of the laser etching head 4 needs to be adjusted for the second time, the laser etching efficiency is greatly improved, and further the production efficiency of Z-shaped parts is greatly improved.
