Description

Technical Field

[0001] This utility model relates to the field of laser technology, and in particular to a direct-fire integrated square tube laser marking machine. Background Technology

[0002] In recent years, the rapid development of the laser technology market has garnered widespread attention, leading to a significant increase in the demand for lasers. Lasers are crucial components of laser equipment, and their design directly determines the overall performance. Existing laser marking machines are large and costly to manufacture. This is partly due to the numerous internal components, making it impossible to accommodate them all within a limited space. This is particularly inconvenient in environments requiring vertical laser equipment for direct marking or frequent relocation. Another issue is insufficient heat dissipation efficiency, further hampered by the limited space. Furthermore, current applications demand lasers that can be quickly adapted and deployed in various situations. This invention aims to address these problems while simultaneously ensuring adequate heat dissipation. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a direct-fire integrated square tube laser marking machine, including a square tube-shaped chassis. The chassis includes a front end face, a rear end face, a top face and a bottom face that are vertically fixedly connected. A connecting plate fixedly connected to the bottom face is provided inside the chassis. A heat dissipation structure is fixed on the upper side of the connecting plate, and a cooling fan is provided on the upper side of the heat dissipation structure. A laser control board is fixedly connected to the side of the connecting plate, and a laser generator is fixedly connected to the side of the heat dissipation structure. A galvanometer structure is fixedly fixed on the inner side of the front end face. The bottom of the galvanometer structure is flush with the connecting plate and fixedly connected to the connecting plate. An isolator is fixedly connected to the galvanometer structure. A light-transmitting hole is provided on the front end face. The galvanometer structure is fixedly connected to the front end face. A blind hole communicating with the light-transmitting hole is provided on the bottom of the blind hole. A second mounting hole and a fourth through hole are provided on the side wall of the blind hole. The galvanometer structure also has a fifth through hole communicating with the fourth through hole. The isolator leads to the fifth through hole. The laser control board is fixedly connected to the galvanometer structure.

[0004] Preferably, the galvanometer structure is configured as a square, comprising a first side surface that fits against the front end face and a second side surface opposite to the first side surface. The galvanometer structure also includes a third side surface, a fourth side surface, a fifth side surface, and a sixth side surface perpendicular to the first and second side surfaces. The blind hole is recessed from the first side surface toward the second side surface. The first mounting hole extends from the bottom of the blind hole to the second side surface. The second side surface has a ┒-shaped protrusion. The inner side of the ┒-shaped protrusion has a first step between it and the second side surface. Half of the first mounting hole extends through the first step, and the other half of the first mounting hole extends through the ┒-shaped protrusion. The ┒-shaped protrusion forms a mounting position with the fourth, fifth, and sixth side surfaces. The sixth side surface has a second step that protrudes outward. Half of the second mounting hole extends through the sixth side surface, and the other half of the second mounting hole extends through the second step.

[0005] Preferably, the galvanometer structure further includes a first laser conversion device installed in a first mounting hole, a second laser conversion device installed in a second mounting hole, and a laser reversing structure installed in the fourth through hole. The first laser conversion device and the second laser conversion device are respectively mounted against the first step and the second step. The isolator is positioned towards the laser reversing structure. The first laser conversion device is provided with a first conversion mirror extending into the blind hole. The second laser conversion device is provided with a second conversion mirror extending into the blind hole. The second conversion mirror is tilted towards the fourth through hole. The first conversion mirror and the second conversion mirror are tilted opposite each other, and the first conversion mirror is tilted towards the opening of the blind hole. The laser control board and the connecting plate are both fixedly connected to the mounting positions.

[0006] Preferably, the heat dissipation structure includes a main plate and heat dissipation teeth fixedly connected to the main plate. A notch is provided at the lower part of the main plate where the main plate connects to the heat dissipation teeth. A notch is provided on the side of the heat dissipation teeth away from the main plate. The heat dissipation teeth are in contact with the laser control board. The laser generating device is fixed on the side of the main plate. A heat dissipation gap is formed between the notch and the laser control board.

[0007] The beneficial effect of this utility model is that it provides a direct-fire integrated square tube laser marking machine. The heat dissipation structure, laser control board, isolator, and galvanometer structure are compactly distributed on the upper part or side of the connecting plate. The heat dissipation structure, laser control board, and galvanometer structure are fixedly connected to the laser plate, making the entire embodiment of the laser marking structure compact, saving space, and reducing the overall size of the equipment. The reduced size lowers transportation costs and also reduces overall costs. The laser emitted by the laser generator passes through the isolator, passes through the through hole five, and is reflected by the laser reversing structure in the through hole four to the first laser conversion device. It is then reflected by the first laser conversion device into the second laser device. After being reflected by the second laser device, the laser exits through the blind hole and faces the product to be marked, thus completing vertical direct-fire laser marking to the outside. The lower part of the main body plate has a notch at the connection between the main body plate and the heat dissipation fins. The side of the heat dissipation fins away from the main body plate has a notch. The heat dissipation fins are in contact with the laser control board. The laser generator is fixed to the side of the main body plate. The heat generated by the laser control board and the laser generator can be quickly dissipated through the main body plate and the heat dissipation fins. A heat dissipation gap is formed between the notch and the laser control board, facilitating heat dissipation. The lower part of the heat dissipation fins penetrates the connecting plate and communicates with the bottom surface of the chassis, resulting in high heat dissipation efficiency.

[0008] This utility model has a compact structure, occupies a small volume, and has good heat dissipation. Attached Figure Description
