Problems solved by technology

[0002] In the field of laser gas cylinder marking, due to errors in the mass production process of gas cylinders, there is a certain tolerance in the outer dimensions of the marking part of the gas cylinders, so that the focal length of the laser head changes during the laser marking process, resulting in The engraved characters will be inconsistent in depth, which will affect the marking quality of products in mass production. However, the existing technology has a fixed focal length and cannot automatically adjust the focal length of laser marking according to changes in the shape and position tolerance of the gas cylinder surface.
During the marking process, scum will appear on the gas cylinder, but in the prior art, the scum is mostly removed manually, which is ineffective and labor-intensive

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] See figure 1 and figure 2 : The laser auto-focusing blowing mechanism shown includes a fixed bracket 1, a fixed lens barrel 2, a fixed plate 3, a fixed sleeve 4, a blowing mechanism, and the focus lens barrel that can move the laser along the beam direction and drive the movement The focusing mechanism and other components for the movement of the focusing lens barrel, the fixed lens barrel 2 is set on the fixed bracket 1, and the fixed lens barrel 2 is attached to the fixed bracket 1 to cover the fixed sleeve 4, and then the fixed sleeve 4 is fixed. Covered with a fastening sleeve 11, the front end of the fixed lens barrel 2 is looped on the moving focusing lens barrel, and the middle part of the moving focusing lens barrel is fixedly sleeved with a holding tube 5, and a fixed lens is arranged below the moving focusing lens barrel. Plate 3, one end of the fix...

Abstract

The invention discloses a laser automatic focusing blow-spraying mechanism. A fixed lens cone is sleeved on a fixing bracket, the fixed lens cone is sleeved with a fixed sleeve clinging to the fixing bracket, the front end of the fixed lens cone is movably sleeved with a movable focusing lens cone, the middle part of the movable focusing lens cone is fixedly sleeved with a holding cylinder, the lower part of the movable focusing lens cone is provided with a retaining plate, and one end of the retaining plate is fixed on the bottom surface of the fixed sleeve, while the other end extends to the front part of the movable focusing lens cone; and the retaining plate is provided with a focusing mechanism, the upper part of the focusing mechanism is movably sleeved on a sliding directional guide rail on the bottom of the movable focusing lens cone, a connecting frame in the focusing mechanism close to the holding cylinder is connected with the holding cylinder through a fine adjustment screw, the front part of the movable focusing lens cone is fixed with a blow-spraying mechanism, and a spray head at the front end of the blow-spraying mechanism is close to a gauge head at the front end of the focusing mechanism. The laser automatic focusing blow-spraying mechanism can adjust the focal distance automatically, can blow and spray dross, and has good marking effect.
