[0025] Please see Figure 1 The processing head assembly provided in this application includes a processing head body 10 and a follower sensor 20. The processing head body 10 is provided with a second signal trigger 11. The follower sensor 20 includes a follower sensor body 21, a breakable connector 22 and a first signal trigger 23. The breakable connector 22 is detachably disposed on the follower sensor body 21 and is used to connect the follower sensor body 21 to the processing head body 10 and to disconnect the follower sensor body 21 from the processing head body 10 when it breaks. The first signal trigger 23 is disposed on the follower sensor body 21 and is used to abut against the second signal trigger 11 of the processing head body 10 so as to separate from the second signal trigger 11 when the follower sensor body 21 is disconnected from the processing head body 10. With this design, when the processing head body 10 is impacted, the breakable connector 22 breaks, causing the follower sensor body 21 to disconnect from the processing head body 10. Simultaneously, the first signal trigger 23 separates from the second signal trigger 11, generating an alarm signal at the processing head body 10, which in turn triggers the cutting machine to stop. Furthermore, after the breakable connector 22 breaks, a spare breakable connector 22 can be used to re-lock and fix the follower sensor body 21 to the processing head body 10, allowing for quick repair and resumption of production.

[0026] The processing head assembly can be a laser head assembly, a cutting head assembly, etc., that is, the processing head body 10 can be a laser head body, a cutting head body, etc., and is not limited here. In this embodiment, the processing head assembly is a cutting head assembly and the processing head body 10 is a cutting head body for example.

[0027] In some embodiments, in order to connect the easily breakable connector 22 to the processing head body 10, the processing head body 10 is provided with a connection hole 12, and the easily breakable connector 22 is connected to the connection hole 12.

[0028] In some embodiments, the servo sensor body 21 is provided with a mounting through hole 211, and a breakable connector 22 is mounted in the mounting through hole 211, with a portion of the breakable connector 22 exposed in the mounting through hole 211 for connecting to the processing head body 10. This design allows the mounting through hole 211 to facilitate replacement and reinstallation of the breakable connector 22 if it breaks.

[0029] Among them, the easily broken connector 22 is a custom-made easily broken screw.

[0030] In some embodiments, there are multiple fragile connectors 22, and each fragile connector 22 is spaced apart on the outer periphery of the follower sensor body 21. Using multiple fragile connectors 22 can improve the connection stability between the follower sensor body 21 and the processing head body 10.

[0031] Specifically, there are four easily breakable connectors 22, which are spaced apart around the perimeter of the servo sensor body 21. It is understood that there may also be three, five or more easily breakable connectors 22, etc., which are not limited here.

[0032] In some embodiments, there are multiple first signal triggers 23, each of which is arranged side-by-side at intervals on the follower sensor body 21. Each first signal trigger 23 can contact or separate from each of the second signal triggers 11 on the processing head body 10. Specifically, there are four first signal triggers 23 and four second signal triggers 11. It is understood that in other embodiments, there may be two, three, five, or more first signal triggers 23 and two signal triggers 11. This is not limited here.

[0033] Furthermore, the first signal trigger 23 includes a first positive contact spring 231 and a first negative contact spring 232, the first positive contact spring 231 and the first negative contact spring 232 are electrically connected, the second signal trigger includes a second positive contact 111 and a second negative contact 112, the second positive contact 111 and the second negative contact 112 are electrically connected, the first positive contact spring 231 can abut or separate from the second negative contact 112, and the first negative contact spring 232 can abut or separate from the second positive contact 111. With this design, when the follower sensor body 21 is connected to the processing head body 10, the first positive contact spring pin 231 contacts the second negative contact spring pin 112, and the first negative contact spring pin 232 contacts the second positive contact 111, making the four contacts electrically connected. When the follower sensor body 21 is separated from the processing head body 10, the first negative contact spring pin 232 separates from the second positive contact 111, and the first positive contact spring pin 231 separates from the second negative contact 112, causing the processing head body 10 to generate an alarm signal.

[0034] Furthermore, the main body 21 of the follow-up sensor is provided with a first groove 212, and the first signal trigger 23 is located within the first groove 212. This design provides protection for the first signal trigger 23 through the physical structure of the groove, preventing it from being directly exposed to the external environment and reducing wear or interference from dust, moisture, and mechanical impacts, thus improving the stability of signal triggering. The groove also serves as a positioning guide structure, ensuring precise alignment of the trigger during installation and preventing false or missed triggering due to misalignment, thus guaranteeing the relative positional accuracy between the trigger and mating components (such as the signal receiver). In addition, the groove design allows for a compact structure, integrating the trigger inside the sensor body, saving external space, making it suitable for installation space-constrained scenarios, and facilitating integration with other components (such as circuit boards and housings), improving the overall structural reliability and assembly efficiency.

[0035] In some embodiments, the servo sensor body 21 is further provided with a first cooling channel, and the servo sensor body 21 is also provided with a cooling water inlet 24 and a cooling water outlet 25, which are sequentially connected. This design, with its circulating structure of cooling water inlet 24 → first cooling channel → cooling water outlet 25, can efficiently remove the heat generated by the servo sensor body 21 during operation through the flow of cooling water, avoiding accuracy degradation, component aging, or failure due to overheating, reducing thermal fatigue damage, and extending service life. In high-temperature industrial and precision measurement scenarios, it can effectively ensure sensor stability and measurement accuracy, while also considering energy saving and environmental protection.

[0036] Specifically, the cooling water inlet 24 and the cooling water outlet 25 are located on the same side of the servo sensor body 21. This design effectively extends the length of the first cooling channel, thereby increasing the flow path for water circulation and improving heat dissipation. It is understood that in other embodiments, the cooling water inlet 24 and the cooling water outlet 25 may be located on opposite sides of the servo sensor body 21; this is not a limitation here.

[0037] In some embodiments, the follower sensor body 21 is further provided with a ceramic ring, and a second cooling channel is provided inside the ceramic ring. The follower sensor body 21 is also provided with a cooling gas inlet 26, which is connected to the second cooling channel, and the cooling gas in the second cooling channel is blown toward the cutting nozzle. With this design, the cutting nozzle on the follower sensor body 21 can be cooled.

[0038] The present invention provides a processing head assembly, including a processing head body 10 and a follower sensor 20. The processing head body 10 is provided with a second signal trigger 11. The follower sensor 20 includes a follower sensor body 21, a breakable connector 22 and a first signal trigger 23. The breakable connector 22 is detachably disposed on the follower sensor body 21 for connecting the follower sensor body 21 to the processing head body 10 and for disconnecting the follower sensor body 21 from the processing head body 10 when it breaks. The first signal trigger 23 is disposed on the follower sensor body 21 for abutting against the second signal trigger 11 of the processing head body 10, so as to separate from the second signal trigger 11 when the follower sensor body 21 is disconnected from the processing head body 10. With this design, when the processing head body 10 is impacted, the breakable connector 22 breaks, causing the follower sensor body 21 to disconnect from the processing head body 10. Simultaneously, the first signal trigger 23 separates from the second signal trigger 11, generating an alarm signal at the processing head body 10, which in turn triggers the cutting machine to stop. Furthermore, after the breakable connector 22 breaks, a spare breakable connector 22 can be used to re-lock and fix the follower sensor body 21 to the processing head body 10, allowing for quick repair and resumption of production.
