Laser automatic focusing blow-spraying mechanism

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.

Description

technical field [0001] The invention belongs to the technical field of marking, and in particular relates to a laser auto-focus blowing mechanism on a laser marking machine. Background technique [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 the laser marking according to the change 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, manual methods are often used to remove the scum, which...

[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
