Description

Technical Field

[0001] This utility model relates to the field of micro laser engraving equipment technology, and in particular to a guide rail type desktop high-speed dual-light engraving device. Background Technology

[0002] Desktop laser marking machines are characterized by high precision, high speed, small size, minimal pattern deformation, and simple operation. They can engrave on most commonly used materials and are therefore gradually becoming more widely used. Commonly used engraving light sources include "blue light", "red light", and "violet light".

[0003] However, existing desktop high-speed dual laser marking machines have the following drawbacks:

[0004] (1) The laser marking machine itself does not have an air filtration device, and an external filtration device is required, which increases the cost and makes the machine peripherals complicated.

[0005] (2) Currently, most desktop laser marking machines use optical rods as guide mechanisms for their automatic focusing and lifting components, which results in insufficient connection strength between the machine body and the laser host, thus affecting the laser focusing accuracy.

[0006] (3) When the protective cover of the laser marking machine moves up and down, it will sway left and right and scratch the machine body. Summary of the Invention

[0007] In view of the above situation, it is necessary to propose a high-speed dual-light engraving equipment for desktop use with air filtration function and stable lifting.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a guide rail type desktop high-speed dual-light engraving device, comprising:

[0009] Base assembly;

[0014] Furthermore, a magnetic bracket and a magnet are provided within the accommodating space. The magnetic bracket is connected to the outer shell assembly, and the magnet is connected to the movable support frame. The magnetic bracket is located above the magnet. When the door cover moves upward to bring the magnet close to the magnetic bracket, the magnet attracts the magnetic bracket.

[0015] Furthermore, the Z-axis slide rail is located on the side of the Z-axis lead screw facing the host module, and each side of the Z-axis slide rail is provided with a sliding clearance hole. Each side of the connecting block assembly is provided with a connecting arm, and the connecting arm is fixedly connected to the host module through the sliding clearance hole.

[0016] Furthermore, the host module includes a host housing with an installation space. The installation space contains a laser module, a galvanometer module, and a field lens module. The working laser generated by the laser module passes through the galvanometer module and the field lens module in sequence and is directed to the working platform of the base assembly.

[0017] Furthermore, the host module also includes a red dot laser, the focal point of which coincides with the initial focal point of the working laser projected onto the working platform through the field lens module.

[0018] Furthermore, the host module also includes a heat dissipation module, which includes a heat dissipation pad disposed at the bottom of the laser module, a heat dissipation block disposed on the laser module, and a heat dissipation fan disposed on the heat dissipation block.

[0021] The beneficial effects of this utility model are as follows: The Z-axis module drives the Z-axis lead screw to rotate via a Z-axis stepper motor, causing the Z-axis nut to move up and down along the Z-axis lead screw. Simultaneously, the connecting block assembly connects the Z-axis nut, Z-axis slider, and main unit module. The Z-axis slider cooperates with the Z-axis slide rail for guiding assistance, improving the connection strength between the main unit module and the Z-axis module, ensuring the lifting stability of the main unit module, and thus guaranteeing the accuracy of Z-axis focusing. An exhaust module with an activated carbon filter is provided.
