Description

Technical Field

[0001] The utility model relates to a focusing mechanism of a laser machine, belonging to the technical field of laser machines. Background Art

[0002] Laser machine is a general term for laser engraving machine, laser cutting machine and laser marking machine. The laser machine uses its high-temperature working principle to act on the surface of the processed material. At the same time, according to the graphics input into the machine, it draws the patterns and texts required by the customer. The focusing mechanism is used to adjust the height of the laser machine so that it reaches the marking position.

[0003] The existing patent number is CN220296113U, which is a focusing mechanism of a laser machine. This device focuses the laser machine body by sliding a slide on the upper end of the laser machine mounting frame, and adjusts the focus of the laser machine body through a focusing component, thereby avoiding focus deviation of the laser machine due to transmission, improving the accuracy of marking, and detecting the inclination of the material marking surface through a material marking surface detection component. The focus is automatically adjusted through synchronization of the focusing component and the material marking surface detection component, and the adjustment operation saves time and effort, is beneficial to operating efficiency, improves the accuracy of marking, and improves the marking quality. However, when this device is in use, the method of using an electric telescopic rod to control the rotation adjustment of the laser machine body is also difficult to maintain stability, and is prone to wear during the repeated up and down sliding of the petals, and is prone to shaking after long-term use, reducing the stability of the device; and the angle of the laser machine is controlled by the action of an angle sensor, which easily causes the focal point of the laser machine to shift or even detach from the device, making it inconvenient to use for marking objects on inclined surfaces.
