[0047] This utility model proposes a laser head assembly 100.

[0048] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the laser head assembly 100 includes a laser head 10 and a cable chain 20. The laser head 10 is provided with a gas channel 13. One end of the laser head 10 along the first direction X is provided as a connecting end 15 and has an air inlet 133 communicating with the gas channel 13. One end of the cable chain 20 is connected to the laser head 10, and at least part of the connecting end 15 is located in the turning area of ​​the cable chain 20.

[0049] The laser head assembly 100 proposed in this application embodiment is used in a laser processing equipment 1000. The laser head assembly 100 is used to emit laser to realize at least one laser processing operation such as laser cutting, laser welding, laser engraving and laser cleaning.

[0050] The laser head 10 includes a mounting base 18 and a laser generating module 16. The mounting base 18 has a mounting cavity 1113 and a laser path 1114. The laser generating module 16 is disposed in the mounting cavity 1113, and the laser generated by the laser generating module 16 can be emitted outward through the laser path 1114. Optionally, the laser generating module 16 can be a semiconductor laser, a carbon dioxide laser, or other lasers.

[0051] The laser head 10 also includes a gas channel 13, and an inlet 133 and an outlet connecting the gas channel 13. In practical applications, protective gas enters the gas channel 13 through the inlet 133 and is then blown towards the processing area through the outlet. This can be used to remove impurities such as molten slag and dust, or to cool the processing area. Optionally, the gas channel 13 can be connected to the laser path 1114, allowing the light output port of the laser path 1114 to be reused as the gas outlet, thus enabling the protective gas to be blown out from the light output port more accurately towards the processing area. Of course, the gas channel 13 and the laser path 1114 can also be independent, with the light output port and the gas outlet being two separate openings.

[0052] In this embodiment, the air inlet 133 of the gas channel 13 is located at the connection end 15 of the laser head 10, so that one end of the cable chain 20 is connected to the connection end 15. The flexible hose for connecting the air inlet 133 can be inserted through the cable chain 20 and extend along the cable chain 20 to the connection end 15 to connect with the air inlet 133, thereby facilitating the connection between the flexible hose and the air inlet 133, reducing the wiring path of the flexible hose and reducing the wiring difficulty. The cable chain 20 is bent and extended around the connection end 15 of the laser head 10, so that the connection end 15 of the laser head 10 is located in the turning area of ​​the cable chain 20, thereby making the structural positions of the laser head 10 and the cable chain 20 relatively compact, with a high overall space utilization rate, which is beneficial to reducing the overall structural size.

[0053] Optionally, the gas channel 13 can be formed directly on the mounting base 18, or at least part of the gas channel 13 can be constructed by setting the gas pipe 12 as in the following embodiment, without limitation.

[0054] Please see Figures 2 to 4 In one embodiment, the laser head 10 includes a laser head body 11 and an air tube 12. The laser head body 11 has a first air passage 131. The air tube 12 passes through the laser head body 11 and forms a second air passage 132. One end of the air tube 12 extends to a connecting end 15 and is provided with an air inlet 133. The end of the air tube 12 away from the air inlet 133 is connected to the laser head body 11 and communicates with the first air passage 131, so that the first air passage 131 and the second air passage 132 are connected to form a gas channel 13.

[0055] In this embodiment, the gas channel 13 in the laser head 10 is formed by connecting the first gas path 131 in the laser head body 11 and the second gas path 132 formed by the gas tube 12. The gas channel 13 is partially constructed using the gas tube 12. The turning point in the second gas path 132 is arc-shaped, which can reduce the airflow resistance. The gas tube 12 is inserted into the laser head body 11, which can protect the gas tube 12.

[0056] Please see Figure 3 and Figure 4In one embodiment, the laser head body 11 includes a main structure 111 and a connecting seat 112. The main structure 111 is provided with a first air passage 131 and a connecting end 15. The connecting seat 112 is located on one side of the main structure 111 along the second direction Y, which intersects with the first direction X. The air pipe 12 passes through the connecting seat 112, and one end of the drag chain 20 is connected to the connecting seat 112.

[0057] In this embodiment, the laser head body 11 includes a connecting seat 112 and a main structure 111 connected together. The main structure 111 is provided with structures such as a laser generating module 16 and a laser path 1114. The connecting seat 112 is located on one side of the main structure 111 along the second direction Y, and the connecting seat 112 and the main structure 111 are detachably connected, which facilitates the disassembly and assembly of the air tube 12.

[0058] Taking the first direction X as the horizontal sliding direction of the laser head assembly 100 as an example, the second direction Y can be parallel to the horizontal direction and set at an angle to the first direction X. Alternatively, the second direction Y can be a vertical direction, and the connecting seat 112 is located on the upper or lower side of the main structure 111.

[0059] See also Figure 3 and Figure 4 In one embodiment, the connecting seat 112 is provided with a limiting groove 1121, in which the air tube 12 is limited and installed. This arrangement helps to improve the stability of the installation position of the air tube 12, reduce the risk of air tube 12 misalignment, and improve the overall structural stability.

[0060] Please see Figures 1 to 3 In one embodiment, the laser head body 11 includes a first part 1111 and a second part 1112. The first part 1111 is provided with a laser generating module 16 and a connecting end 15. The width of the first part 1111 along the second direction Y is less than the turning diameter of the cable chain 20. The second part 1112 is connected to the end of the first part 1111 away from the connecting end 15. The length of the second part 1112 along the second direction Y is greater than the length of the first part 1111 along the second direction Y. The connecting seat 112 is located in the angle region between the first part 1111 and the second part 1112. The second part 1112 is provided with a laser path 1114 and a first air path 131. The laser generated by the laser generating module 16 is emitted outward through the laser path 1114.

[0061] In this embodiment, the laser head body 11 includes a first part 1111 and a second part 1112. A laser generating module 16 is disposed in the first part 1111, and a laser path 1114 is disposed in the second part 1112. The laser generated by the laser generating module 16 is emitted outward through the laser path 1114. The length of the second part 1112 along the second direction Y is greater than the length of the first part 1111 along the first direction X. The projections of the first part 1111 and the second part 1112 onto surfaces parallel to the first direction X and the second direction Y are perpendicular to each other, forming an included angle region. A connecting seat 112 is disposed in the included angle region and covers one side of the first part 1111 along the first direction X. This arrangement utilizes the included angle region of the first part 1111 and the second part 1112 for mounting the connecting seat 112, resulting in high space utilization, a compact overall structure of the laser head 10, and a reduction in the size of the laser head 10.

[0062] The first part 1111 is provided with a connecting end 15, so that the first part 1111 is located in the turning area of ​​the cable chain 20, and the width of the first part 1111 along the second direction Y is smaller than the turning diameter of the cable chain 20, thereby avoiding the laser head 10 from affecting the bending of the cable chain 20. When the laser head 10 is applied to the laser processing equipment 1000 and is driven by the moving component 300 to move along the first direction X, the cable chain 20 can deform and move along with the laser head 10 without interfering with the laser head 10.

[0063] In some embodiments, the laser head 10 is also provided with a coolant channel 14. The coolant channel 14 can be provided in the first part 1111 where the laser generating module 16 is located, so that the laser generating module 16 can have a higher heat dissipation efficiency. Of course, some of the coolant channels 14 can also be provided in the second part 1112 to dissipate heat from the devices in the second part 1112 and improve the heat dissipation efficiency.

[0064] Please see Figure 8 In one embodiment, the first air passage 131 extends vertically, and the air inlet 1311 of the first air passage 131 is located above the air outlet 1312.

[0065] With this configuration, the first air passage 131 has fewer bends, and the airflow does not need to go through multiple turns when flowing through the first air passage 131, which makes the airflow smooth and helps to reduce airflow loss.

[0066] See also Figure 1 and Figure 3 In one embodiment, the airflow inlet 1311 of the first air passage 131 is located on the side of the second part 1112 facing the angled region and is offset from the connecting seat 112.

[0067] In this embodiment, the airflow inlet 1311 of the first air passage 131 is misaligned with the connecting seat 112, and the air outlet of the air pipe 12 extends from the connecting seat 112 to communicate with the airflow inlet 1311 of the first air passage 131. With this arrangement, the connection position between the air pipe 12 and the second part 1112 will not be blocked by the connecting seat 112, which is beneficial to improving the ease of disassembly and assembly.

[0068] Please see Figures 3 to 7 In one embodiment, the laser head 10 is further provided with a coolant channel 14, and the connecting end 15 is further provided with an inlet 145 and an outlet 146 that communicate with the coolant channel 14.

[0069] In this embodiment, a coolant channel 14 is provided in the laser head 10. The coolant channel 14 serves as a passage for coolant flow, using liquid cooling to remove heat from the laser head 10, giving the laser head 10 high heat dissipation performance and ensuring stable performance during processing. This improved heat dissipation also allows for the use of a higher-power laser generation module 16 in the laser head 10, enhancing laser processing efficiency and quality. It also enables the processing of harder and thicker materials, increasing the applicability of laser processing. The inlet 145 and outlet 146 of the coolant channel 14 are located at the connection end 15, adjacent to the air inlet 133. This arrangement allows the inlet pipe connecting to the inlet 145 and the outlet pipe connecting to the outlet 146 to directly connect to them when passing through the cable chain 20, eliminating the need for additional wiring and improving connection convenience.

[0070] When the laser head 10 is applied to the laser processing equipment 1000, the inlet 145 and the outlet 146 are connected to the cooling system so that the coolant flow channel 14 and the cooling system form a coolant circuit. The coolant with a lower temperature can enter the coolant flow channel 14 from the inlet 145, exchange heat with the laser head 10 to absorb the heat of the laser head 10, and then flow out from the outlet 146 to enter the cooling system. The cooling system can cool down the heated coolant so that the temperature of the coolant is reduced and then flows back into the coolant flow channel 14.

[0071] See also Figure 6 and Figure 7 In one embodiment, the coolant flow channel 14 includes a first flow path 141 disposed on the laser head body 11, and an inlet flow path 142 and an outlet flow path 143 disposed on the connecting seat 112. The inlet 145 is connected to the inlet flow path 142, and the outlet 146 is connected to the outlet flow path 143. The inlet flow path 142 and the outlet flow path 143 are respectively connected to the first flow path 141.

[0072] In this embodiment, the connector 112 serves as both an inlet connector and an outlet connector. When the connector 112 is connected to the laser head body 11, the liquid inlet of the first flow path 141 and the liquid outlet of the inlet flow path 142 can be directly positioned opposite each other and connected to each other. At the same time, the liquid outlet of the first flow path 141 and the liquid inlet of the outlet flow path 143 can be positioned opposite each other and connected to each other. There is no need to set other connecting pipes between the first flow path 141 and the inlet flow path or between the first flow path 141 and the outlet flow path, which makes disassembly and assembly convenient.

[0073] Please see Figure 3 and Figure 7 In one embodiment, the laser head 10 is provided with a mounting cavity 1113, the laser generating module 16 of the laser head 10 is disposed in the mounting cavity 1113, and at least a portion of the coolant flow channel 14 is disposed in the side wall for enclosing and forming the mounting cavity 1113.

[0074] In this embodiment, a coolant channel 14 is provided on the side wall of the mounting cavity 1113 for mounting the laser generating module 16. The coolant channel 14 is located adjacent to the laser generating module 16, which can efficiently remove the heat of the laser generating module 16 and has high heat dissipation efficiency, so that the laser head 10 has good heat dissipation performance.

[0075] Optionally, a coolant flow channel 14 may be provided on one side wall of the mounting cavity 1113, or a coolant flow channel 14 may be provided on at least two side walls; there is no limitation on this.

[0076] In some embodiments, the laser head 10 is provided with two opposing first sidewalls, and the mounting cavity 1113 is located between the two first sidewalls. Both first sidewalls are provided with a first flow path 141 of the coolant flow channel 14. This arrangement helps to increase the flow path of the coolant in the laser head 10, increase the heat exchange area between the coolant and the laser head 10, and improve the heat dissipation efficiency of the laser head 10.

[0077] Please see Figure 7 In some embodiments, the coolant flow channel 14 further includes a second flow channel 144 for connecting the two first flow channels 141, and the second flow channel 144 may be disposed on either side wall connecting the two first side walls.

[0078] Please see Figure 1 In one embodiment, the laser head 10 is further provided with a conductive cable 17, which extends to the connection end 15 to enter the cable chain 20.

[0079] When the laser head 10 is used in the laser processing equipment 1000, the conductive cable 17 of the laser head 10 is used to connect to the controller and can be used to transmit control signals and electrical energy, etc. Extending the conductive cable 17 to the connection end 15 of the laser head 10 allows the conductive cable 17 to enter the cable carrier 20 and be routed along the cable carrier 20. This protects the conductive cable 17 and prevents it from twisting or interfering with other devices when the laser head 10 moves.

[0080] Please refer to Figure 9 This utility model also proposes a laser processing device 1000, which includes a processing platform 200, a moving component 300, and a laser head assembly 100. The specific structure of the laser head assembly 100 is as described in the above embodiment. The laser head assembly 100 is positioned above the processing platform 200 and connected to the moving component 300, which drives the laser head assembly 100 to move. Optionally, the moving component 300 drives the laser head assembly 100 to move horizontally, allowing it to move to different positions and perform laser processing on different areas of the workpiece. The laser processing can be, but is not limited to, laser cutting, laser welding, laser engraving, laser marking, and laser cleaning, among others.

[0081] Optionally, the moving component 300 is used to drive the laser head assembly 100 to move along a first direction X. In some embodiments, the moving component 300 can be used to drive the laser head assembly 100 to move in a first direction X and a second direction Y, where the second direction Y intersects the first direction X. For example, the moving component 300 includes a first slide rail and a second slide rail whose extending directions intersect. The second slide rail is slidably disposed on the first slide rail, and the laser head 10 is slidably disposed on the second slide rail, so that the laser head assembly 100 can slide along the second slide rail or slide along the first slide rail with the second slide rail. In some embodiments, the moving component 300 may also include a lifting mechanism for controlling the raising and lowering of the laser head assembly 100.
