Laser processing equipment incorporates a Z-axis drive mechanism on the laser processing head to achieve precise control and dynamic adjustment of the laser head in the normal direction of the workpiece surface. However, existing Z-axis drive mechanisms are bulky and occupy a large amount of space, limiting the movement speed of the laser processing head. Therefore, it is essential to provide a laser head module and laser processing equipment that is smaller in size, reduces space requirements, and increases movement speed. Utility Model Content

Preferred embodiments of this application are shown in the drawings. However, this application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0029] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. It should be noted that the first direction z and the second direction y in this application are respectively parallel to the z-axis and y-axis in the spatial coordinate system.

[0030] Example:

[0031] In a first aspect, embodiments of this application provide a laser head module, see [link to relevant documentation]. Figures 1 to 7 As shown, the device includes a z-axis drive assembly 1 and a laser processing head 2 driven by the z-axis drive assembly 1. The z-axis drive assembly 1 is configured to drive the laser processing head 2 to move along a first direction z. The z-axis drive assembly 1 includes a drive member 11 arranged along a second direction y, a first transmission member 12 disposed at the output end of the drive member 11, a second transmission member 13 connected to the first transmission member 12 and arranged along the first direction z, and a mounting plate 14 fixedly connected to the second transmission member 13. The laser processing head 2 is disposed on the mounting plate 14, and the drive member 11 is disposed on the side of the mounting plate 14 opposite to the laser processing head 2. The second direction y and the first direction z are perpendicular to each other in space.

[0032] This application provides a laser head module, which includes a z-axis drive assembly 1 for driving the laser processing head 2 to move along a first direction z. The z-axis drive assembly 1 transmits the rotational motion of the drive member 11 into the linear motion of the mounting plate 14 along the first direction z, providing the laser processing head 2 with a driving force to move along the first direction z. The drive member 11 in the z-axis drive assembly 1 is arranged along a second direction y perpendicular to the first direction z, which reduces the space occupied by the laser head module in the first direction z, provides sufficient installation space for other components, improves the utilization rate of the limited installation space, helps to reduce the overall volume of the laser head module, and increases the moving speed of the laser head module.

[0033] It is understood that the z-axis drive assembly 1 provided in this application can be applied not only to the laser head module, but also to other devices used for linear drive of workpieces, so as to reduce the space occupied by the device and reduce production costs.

[0034] Optionally, the first transmission component 12 is a transmission gear, and the second transmission component 13 is a rack that meshes with the first transmission component 12. In this application, the first transmission component 12 and the second transmission component 13 are connected by the meshing of the transmission gear and the rack to transmit the driving force of the driving component 11 to the mounting plate 14, thereby driving the mounting plate 14 to move along the first direction z. Compared with the screw drive structure, the gear meshing structure has lower precision requirements, lower processing difficulty, and lower manufacturing cost, and also lower requirements for environmental cleanliness.

[0035] Optionally, the z-axis drive assembly 1 further includes a guide shaft 15, which is disposed along the first direction z, and the mounting plate 14 is slidably connected to the guide shaft 15. Specifically, in some embodiments, the mounting plate 14 includes a mounting plate body 141 and a sliding connection portion 142 disposed on the side of the mounting plate body 141. The sliding connection portion 142 has a first hole structure 143, and the guide shaft 15 is disposed through the first hole structure 143. The arrangement of the guide shaft 15 guides the movement of the mounting plate 14 along the first direction z, improving the stability of the movement of the mounting plate 14 along the first direction z, thereby improving the stability of the movement of the laser processing head 2 along the first direction z. Optionally, in other embodiments, a linear bearing is provided between the first hole structure 143 and the guide shaft 15. The arrangement of the linear bearing improves the smoothness and stability of the movement of the mounting plate 14 in the first direction z.

[0036] Optionally, the cross-sectional thickness of the mounting plate body 141 is smaller than the cross-sectional thickness of the sliding connection portion 142, and the second transmission member 13 is disposed close to the sliding connection portion 142; the cross-section refers to the plane of the mounting plate 14 perpendicular to the first direction z. The structural configuration of the mounting plate 14 makes the thickness of the mounting plate body 141 relatively thinner than the thickness of the sliding connection portion 142. While ensuring that the mounting plate 14 supports the laser processing head 2 and cooperates with the guide shaft 15, it avoids occupying the installation space of the mounting plate 14 and further ensures the effective utilization of the installation space of the laser head module.

[0037] Optional, see Figure 1 and Figure 2As shown, the z-axis drive assembly 1 further includes a housing 16, and the drive member 11, the first transmission member 12, the second transmission member 13, the mounting plate 14, and the guide shaft 15 are housed within the housing 16. The drive member 11 is fixedly connected to the inner wall of the housing 16, and both ends of the guide shaft 15 are respectively connected to the housing 16.

[0038] Optional, see Figures 3 to 8 As shown, the z-axis drive assembly 1 further includes an elastic limiting member 17 disposed along the first direction z. The elastic limiting member 17 is configured to limit the movement of the laser processing head 2 along the first direction z. One end of the elastic limiting member 17 is connected to the inner wall of the housing 16, and the other end is connected to the mounting plate 14. In the case of power failure, the elastic limiting member 17 is in a naturally relaxed state, and the mounting plate 14 is supported on the elastic limiting member 17.

[0039] In the event of a power outage, the elastic limiting member 17 suspends the laser processing head 2 mounted on the mounting plate 14 by supporting the mounting plate 14, preventing the laser processing head 2 from falling or colliding, thus protecting the laser processing head 2. When the mounting plate 14 moves along the first direction z, the mounting plate 14 and the laser processing head 2 mounted on it move synchronously. The movement of the mounting plate 14 applies a force to the elastic limiting member 17. When the mounting plate 14 moves to a set stroke, the elastic limiting member 17 prevents the mounting plate 14 from moving further by applying a reaction force to the mounting plate 14, thereby achieving a mechanical limiting effect on the mounting plate 14. In addition, the elastic limiting member 17 provides a restoring force to the mounting plate 14 during its return movement, improving return efficiency and reducing energy waste.

[0040] Optional, see Figure 8 As shown, the elastic limiting member 17 is a compression spring, which is sleeved on the guide shaft 15. Both ends of the compression spring are connected to the inner wall of the housing 16 and the sliding connection portion 142, respectively. The compression spring extends into the first hole structure 143, which has a limiting protrusion 144. The first hole structure 143 limits the end of the compression spring by restricting the end of the elastic limiting member 17 while preventing the end of the compression spring from twisting.

[0041] Optional, see Figures 2 to 4As shown, the laser head module also includes a reset switch 3 and a flame detection component 4. The flame detection component includes a flame detection main board 41 and a flame detection sensor 42 and a limit switch 43 disposed on the flame detection main board 41. The reset switch 3 is configured to detect the position of the laser processing head 2 to reset the laser processing head 2 to zero. The flame detection sensor 42 is configured to detect whether there is a fire. The limit switch 43 is configured to detect whether the movement of the laser processing head 2 exceeds a predetermined stroke and to issue an alarm signal after exceeding the predetermined stroke.

[0042] The sensor system ensures that the laser processing head 2 maintains a consistent position during each startup or reset by setting the reset switch 3, thus guaranteeing the operational accuracy of the laser head module. The flame detection sensor 42 monitors the status of the laser head module in real time, detecting whether there is fire in the environment, thereby improving safety and reliability. The limit switch 43 prevents the laser processing head 2 from moving beyond the safe range, thus avoiding mechanical damage to the laser processing head 2.

[0043] Optional, see Figure 2 As shown, the laser head module also includes a cooling system 5, which is connected to the laser processing head 2 and configured to cool the laser processing head 2. In some embodiments, the cooling system 5 is an air-cooled system, which includes an air duct and a cooling fan. The air duct is connected between the laser processing head 2 and the cooling fan. The cooling system 5 cools the laser processing head 2, maintaining its stability and preventing damage to the laser head module due to overheating. Furthermore, the laser head module also includes a cable chain box 18 disposed on the housing 16, which houses the air duct and connecting wires. The cable chain box 18 improves the integration and aesthetics of the laser head module.

[0044] Secondly, embodiments of this application provide a laser processing device, which includes the laser head module as described above.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above embodiments merely illustrate preferred implementations of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
