[0084] The utility model provides a kind of laser 100.

[0085] Please refer to Figures 2 to 4In some embodiments of the present application, the laser 100 comprises a housing 10, a laser module 20 and a lifting module 30. The housing 10 has a receiving cavity 11 formed therein, and the bottom of the receiving cavity 11 has an opening. At least part of the laser module 20 is arranged in the receiving cavity 11, and the laser module 20 is arranged to be lifted relative to the housing 10, and the light outlet 23 of the laser module 20 is arranged to face the opening below. The lifting module 30 is arranged in the receiving cavity 11 and is in transmission connection with the laser module 20, and is used to drive the laser module 20 to lift.

[0086] The laser 100 provided in the present application can be applied in a laser processing equipment 1 such as a laser marking machine, a laser engraving machine, a laser cutting machine, etc., and is used to emit laser. The laser 100 comprises a housing 10 as a bearing and mounting base, the housing 10 has a receiving cavity 11 formed therein, and the bottom of the housing 10 is provided with an opening communicating with the receiving cavity 11. At least part of the laser module 20 is arranged in the receiving cavity 11, and the laser module 20 can be lifted relative to the housing 10. The laser module 20 can be always located in the receiving cavity 11 and lifted only in the receiving cavity 11, and the light outlet 23 of the laser module 20 faces the opening at the bottom of the housing 10 to emit laser outward. Alternatively, the laser module 20 can be lifted and moved in and out of the receiving cavity 11 from the opening at the bottom of the housing 10, and the height of the laser module 20 can be adjusted to adjust the height of the laser focal point, so that the laser focal point can fall on the processing position.

[0087] The laser 100 is further provided with a lifting module 30, which can be a screw transmission structure, a cylinder or a liquid cylinder pushing structure, a linear motor structure, a turbine worm structure or a gear rack structure, etc. The lifting module 30 is in transmission connection with the laser module 20, so that the laser module 20 can be driven to lift by the lifting module 30.

[0088] Therefore, it can be understood that the technical solution of the present application, the laser module 20 in the laser 100 can be lifted in the housing 10 driven by the lifting module 30 to adjust the height position of the laser focal point. In this way, when the laser 100 is applied in the laser processing equipment 1, the laser 100 is fixed at the same height position by the housing 10, and the laser module 20 or part of the structure containing the laser module 20 is driven to lift by the lifting module 30 in the laser 100 to adjust the height position of the laser focal point, so that the laser 100 as a whole does not need to be lifted in the laser processing equipment 1, and the lifting process for adjusting the height of the laser focal point is more convenient.

[0089] In combination with reference Figures 3 to 6In some embodiments of the present application, the top of the shell 10 is provided with a heat dissipation opening 12 communicating with the accommodating cavity, and the laser 100 further comprises a heat dissipation module 40, which comprises a heat dissipation fan 41. The heat dissipation fan 41 is arranged in the accommodating cavity 11 and located above the laser module 20. The air outlet of the heat dissipation fan 41 is arranged towards the laser module 20.

[0090] In the present embodiment, the laser 100 further comprises a heat dissipation module 40 arranged in the accommodating cavity 11 for dissipating heat for the structures in the accommodating cavity 11. Specifically, the heat dissipation module 40 comprises a heat dissipation fan 41 arranged on the top of the laser module 20. A heat dissipation opening 12 is formed in the bottom wall of the accommodating cavity 11. In this way, the heat dissipation fan 41 can drive external air to flow into the accommodating cavity 11 and flow downward to dissipate heat for the structures in the accommodating cavity 11. Moreover, the heat dissipation fan 41 is fixedly connected with the shell 10, so that the heat dissipation fan 41 does not need to be raised and lowered with the laser module 20, thereby making the process of raising and lowering the laser module 20 more convenient.

[0091] In combination with reference to Figure 6 and Figure 10 In some embodiments of the present application, a mounting plate 14 is arranged in the accommodating cavity 11. The mounting plate 14 is provided with a ventilation opening 141. The heat dissipation fan 41 is arranged on the upper surface of the mounting plate 14 and arranged towards the ventilation opening 141. The laser module 20 is arranged below the mounting plate 14.

[0092] In the present embodiment, the mounting plate 14 is arranged in the accommodating cavity 11. The mounting plate 14 is fixedly connected with the shell 10 and provided with the ventilation opening 141. The heat dissipation fan 41 is fixedly arranged on the upper surface of the mounting plate 14, and the air outlet of the heat dissipation fan 41 is arranged towards the ventilation opening 141. In this way, the heat dissipation fan 41 can be prevented from being suspended in the air, thereby improving the stability of the heat dissipation fan 41 fixed in the accommodating cavity 11. Moreover, the arrangement of the mounting plate 14 will not affect the heat dissipation fan 41 driving air to dissipate heat for the laser module 20 and other structures.

[0093] In combination with reference to Figure 7 In some embodiments of the present application, the heat dissipation module 40 further comprises a first heat sink 42 connected to the side of the laser module 20. The side of the first heat sink 42 away from the laser module 20 is provided with a plurality of first heat dissipation fins 423 arranged side by side in the horizontal direction.

[0094] In the embodiment, the heat dissipation module 40 further comprises a first heat sink 42 arranged on the side wall of the laser module 20. The first heat sink 42 comprises a plurality of first heat dissipation fins 423 arranged side by side. The first heat sink 42 can be made of a material with good heat conduction and heat dissipation performance, such as aluminum, aluminum alloy, copper, or copper alloy. In this way, the heat on the laser module 20 can be quickly transferred to the first heat sink 42, and the plurality of first heat dissipation fins 423 on the first heat sink 42 form a large heat dissipation area, so that the heat transferred to the first heat sink 42 can be quickly dissipated.

[0095] Please refer to Figure 7 In some embodiments of the present application, the plurality of first heat dissipation fins 423 are arranged in the horizontal direction. In this way, the first heat dissipation fins 423 extend substantially along the flow direction of the airflow driven by the heat dissipation fan 41, and an airflow flow path is formed between adjacent two first heat dissipation fins 423. In this way, when the airflow flows through the first heat sink 42, it can pass through each airflow flow path to make full contact with each first heat dissipation fin 423 to carry away the heat on each first heat dissipation fin 423, thereby improving the heat dissipation efficiency of the first heat sink 42. Moreover, arranging the first heat dissipation fins 423 in the horizontal direction can also avoid the airflow being directly impacted on the surface of the first heat dissipation fins 423, thereby avoiding hindering the normal flow of the airflow.

[0096] Please refer to Figure 6 In some embodiments of the present application, the heat dissipation module 40 further comprises a second heat sink 43 connected to the side of the laser module 20 away from the first heat sink 42. The side of the second heat sink 43 away from the laser module 20 is provided with a plurality of second heat dissipation fins 431 arranged side by side in the horizontal direction.

[0097] In the embodiment, the heat dissipation module 40 comprises the first heat sink 42 and the second heat sink 43. The first heat sink 42 and the second heat sink 43 are arranged on the two sides of the laser module 20 respectively, and are connected to the laser module 20 for absorbing the heat of the laser module 20 and accelerating the heat dissipation of the laser module 20. The structure of the first heat sink 42 is the same as that of the previous embodiment, and will not be described here. The surface of the second heat sink 43 away from the laser module 20 is provided with a plurality of second heat dissipation fins 431, which increase the heat dissipation area, thereby increasing the contact area and heat exchange efficiency of the airflow and the second heat sink 43. In this way, the heat transferred from the laser module 20 to the second heat sink 43 can be quickly dissipated, thereby improving the heat dissipation efficiency.

[0098] Please refer to Figure 6In some embodiments of the present application, the second heat dissipation fins 431 are arranged in a horizontal direction. In this way, the second heat dissipation fins 431 extend in the flow direction of the air flow driven by the heat dissipation fan 41, and the air flow flow path is formed between two adjacent second heat dissipation fins 431, so that the air flow can pass through each air flow flow path when passing through the second heat sink 43, and fully contact each second heat dissipation fin 431 to carry away the heat on each second heat dissipation fin 431, thereby improving the heat dissipation efficiency of the second heat sink 43. In addition, arranging each second heat dissipation fin 431 in a horizontal direction can also avoid the air flow being directly impacted on the surface of the second heat dissipation fin 431 and being hindered, thereby affecting the normal flow of the air flow.

[0126] Please refer to Figure 8 and Figures 9 to 11 In some embodiments of the present application, the laser 100 further comprises an air nozzle module 50. The air nozzle module 50 is arranged on the lower side of the laser module 20 and has a gas guide channel 513, a flow guide cavity 521 and an outlet 522. The flow guide cavity 521 is in communication with the gas guide channel 522. The gas guide channel 513 can be connected to a gas source and guide the gas flow to the flow guide cavity 521. The gas flow is blown out from the outlet 522 after passing through the flow guide cavity 521. The light outlet 23 of the laser module 20 is located in the flow guide cavity 521, and the center line of the outlet 522 coincides with that of the light outlet 23.

[0127] It can be understood that dust and smoke will be generated during the laser processing.

The gas supply structure 300 supplies the gas flow to the air nozzle module 50. The gas flow supplied by the gas supply structure 300 is blown out from the outlet 522 in sequence through the gas guide channel 513, the flow guide cavity 521 and the outlet 522. In this way, the dust and smoke outside the outlet 522 can be blown away. The continuous flow of the gas flow can also prevent the dust and other impurities from entering the flow guide cavity 521 and the light outlet 23 of the laser module 20 or adhering to the window lens or the focusing lens, so as to avoid affecting the laser emission. Moreover, the air nozzle module 50 is fixed on the laser module 20 and can be lifted together with the laser module 20, so that the air nozzle module 50 can always form a gas flow in front of the air nozzle 52 of the laser module 20, and the gas flow can also be blown to the position to be processed to prevent the position to be processed from being contaminated by dust, thereby achieving a good dustproof effect and ensuring the processing effect.

[0145] Please refer to Figure 10 and Figure 9 In some embodiments of the present application, the housing 10 is provided with a mounting opening 13, and the laser device 100 further includes an air inlet connector 90 and an air guide hose 55. The air inlet connector 90 is arranged in the accommodating cavity 11 and arranged in the mounting opening 13. The air guide hose 55 is bent and extends in the accommodating cavity 11, one end of the air guide hose 55 is in communication with the mounting opening 13, and the other end of the air guide hose 55 is in communication with the air nozzle module 50. The air guide hose 55 is adaptively deformed with the lifting of the laser module 20.

[0146] In the embodiment, the laser module 20 and other components in the laser device 100 can be lifted, while the shell 10 and part of the structure are fixed, so that the process of adjusting the height of the laser focal point is more convenient. In the embodiment, a mounting port 13 is formed on the shell 10, the air inlet connector 90 is arranged at the position of the mounting port 13, and the air guide hose 55 is arranged in the accommodating cavity 11. The air guide hose 55 can be deformed and bent according to the requirement. The air guide hose 55 can be made of plastic, rubber, PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene) or the like. One end of the air guide hose 55 is connected with the air inlet connector 90, and the other end of the air guide hose 55 is communicated with the air nozzle module 50. The length of the air guide hose 55 is greater than the straight-line distance between the air nozzle module 50 and the air inlet connector 90, and the air guide hose 55 is partially bent. In this way, when the air nozzle module 50 is lifted with the laser module 20, the air guide hose 55 can be deformed to follow the movement of the air nozzle module 50, so as to keep the connection between the air guide hose 55 and the air nozzle module 50, stabilize the airflow and ensure the blowing and dust removing effect.

[0147] In the embodiment, the external air source is connected to the air inlet connector 90 fixed on the shell 10, and the shell 10 does not move up and down in the laser processing equipment 1. Therefore, when the height of the laser module 20 and the air nozzle module 50 is adjusted, the connection structure between the external air source and the laser device 100 is not pulled up and down with the laser module 20 and the air nozzle module 50. In addition, a long connection structure does not need to be reserved to adapt to the lifting of the laser module 20, so that interference is avoided, and the stability and safety of the lifting process of the laser module 20 are improved.

[0148] Please refer to Figure 12 and Figure 6 In some embodiments of the present application, the air guide hose 55 is located on the side of the laser module 20. The air pipe connector 56 includes the first connector 561 and the second connector 562 arranged at an angle. The first connector 561 is inserted into the connecting port, and the second connector 562 is arranged upward. The second connector 562 is inserted into one end of the air guide hose 55.

[0149] In the embodiment, the air pipe connector 56 includes the first connector 561 inserted into the connecting port of the air guide member 51, and the second connector 562 communicated with the first connector 561. The second connector 562 extends upward along the lifting direction of the laser module 20. Therefore, when the air guide hose 55 is connected to the air pipe connector 56, the air guide hose 55 extends along the height direction. The bending deformation direction of the air guide hose 55 is the same as the lifting direction of the laser module 20 and the air nozzle module 50. Therefore, the air guide hose 55 does not interfere with the lifting of the laser module 20, and the airflow is stable.

[0150] Please refer to Figure 6In some embodiments of the present application, the laser 100 further comprises a position detection module 60 arranged in the accommodating cavity 11 and configured to detect the position of the laser module 20.

[0151] In the embodiments of the present application, the laser module 20 is arranged in a liftable manner relative to the shell 10, so that the height of the light outlet 23 of the laser module 20 can be adjusted according to the height of different processing positions, thereby improving the processing precision and processing effect. In addition, before each laser processing, the laser module 20 needs to be lifted and reset to a preset original position, so as to facilitate the control of the operation of the lifting module 30 to lower the laser module 20 to the required position. In the embodiments of the present application, the position detection module 60 is arranged in the laser 100 and configured to detect the position of the laser module 20. The position detection module 60 can detect the height of the laser module 20, or can be configured to detect whether the laser module 20 is lifted and reset to the preset original position, thereby improving the height adjustment precision of the laser module 20. The position detection module 60 can be at least one of a proximity switch, a photoelectric detection switch, a grating ruler detection module, a Hall sensor, etc., which is not limited herein.

[0152] With reference to Figure 15 , Figure 16 and Figure 15 In some embodiments of the present application, the position detection module 60 is configured to detect whether the laser module 20 is lifted and reset to the preset original position. The position detection module 60 comprises a mounting shell 61, a sensing module 63, and a first reset member 65. The mounting shell 61 is provided with a mounting cavity 613 and a first through hole 614 in communication with the mounting cavity 613. The sensing module 63 comprises a movable member 631, a first trigger member 633, and a first sensing member 635. The movable member 631 is movably arranged in the first through hole 614 and has a first position and a second position. The first trigger member 633 and the first sensing member 635 are both arranged in the mounting cavity 613. One of the first trigger member 633 and the first sensing member 635 is arranged on the movable member 631, and the other of the first trigger member 633 and the first sensing member 635 is connected with the mounting shell 61. The first trigger member 633 triggers the first sensing member 635 when the movable member 631 is at the first position. The first reset member 65 is arranged in the mounting cavity 613 and acts on the movable member 631, so that the movable member 631 has a tendency to be kept at the second position.

[0153] Specifically, the mounting shell 61 is used as the mounting base of the position detection module 60, and the mounting cavity 613 is formed in the mounting shell 61. The outer contour of the mounting shell 61 can be a cuboid, a square, a cylinder, a prism, or other regular or irregular structures. The mounting cavity 613 formed in the mounting shell 61 can be shaped according to the outer contour or can be set to other shapes. The mounting shell 61 can include an upper shell 611 and a lower shell 612 that are coupled to each other, or can be set to a side-opening door structure to open the mounting cavity 613 to disassemble the internal structure. The movable part 631 of the sensing module 63 is arranged in the first through hole 614 of the mounting shell 61 and extends out of the mounting cavity 613. The movable part 631 can slide along the central axis of the first through hole 614 relative to the mounting shell 61 and has a first position and a second position. In addition, the first reset part 65 is arranged between the movable part 631 and the mounting shell 61. The first reset part 65 can be an elastic part such as a spring, a gas spring, an elastic air bag, etc. The elastic part can be arranged on the side of the top wall opposite to the first through hole 614 and applies an elastic pushing force to the movable part 631 towards the side of the first through hole 614, so that the movable part 631 has a tendency to move from the first position to the second position and remain in the second position. The elastic part can also be arranged on the cavity wall where the first through hole 614 is formed and connected with the movable part 631 to apply an elastic pulling force to the movable part 631, so that the movable part 631 also has a tendency to move from the first position to the second position and remain in the second position. The first reset part 65 can also be a magnetic structure. The magnetic structure can include a first magnetic part and a second magnetic part arranged on the movable part 631 and the mounting shell 61, respectively. The first magnetic part and the second magnetic part can have a magnetic attraction force, which makes the movable part 631 have a tendency to move from the first position to the second position and remain in the second position. The first magnetic part and the second magnetic part can also have a magnetic repulsion force, which can be used to push the movable part 631 to have a tendency to move from the first position to the second position and remain in the second position. When the movable part 631 is moved into the mounting cavity 613 by an external force, the action force applied by the first reset part 65 can be overcome. When the external force acting on the movable part 631 is removed, the action force applied by the first reset part 65 to the movable part 631 can move the movable part 631 to the second position.

[0154] The induction module 63 further comprises a first trigger 633 and a first induction element 635 arranged in the mounting cavity 613. The first induction element 635 can be connected with the mounting shell 61, and the first trigger 633 is arranged on the movable element 631 so that the first trigger 633 moves relative to the first induction element 635 along with the movable element 631. When the movable element 631 moves from the second position to the first position, the first trigger 633 triggers the first induction element 635 to generate an induction signal. In the embodiment of the present application, the first trigger 633 can also be connected with the mounting shell 61, and the first induction element 635 is arranged on the movable element 631 so as to move relative to the first trigger 633 along with the movable element 631. When the movable element 631 moves from the second position to the first position, the first trigger 633 can also trigger the first induction element 635 to generate an induction signal.

[0155] The first induction element 635 can be a Hall sensor, a photoelectric switch, a proximity switch, a grating reading head, etc. For example, the first induction element 635 is a Hall sensor, and the first trigger 633 is a magnet 53. When the first trigger 633 moves along with the movable element 631 between the first position and the second position, the magnetic field strength around the Hall sensor changes, for example, from weak to strong or from strong to weak. The magnetic field strength detected by the Hall sensor when the first trigger 633 is in the first position is used as a trigger condition, so that the Hall sensor generates an induction signal when the first trigger 633 reaches the first position. If the proximity switch is used as the first induction element 635, the first trigger 633 can touch the sensing surface of the proximity switch when the movable element 631 is in the first position, so that the proximity switch generates an induction signal. If the grating reading head is used as the first induction element 635, and the first trigger 633 is a scale grating extending along the moving direction of the movable element 631. When the movable element 631 moves from the second position to the first position, the scale grating moves relative to the grating reading head. The grating reading head can read the displacement of the scale grating relative to the grating reading head, and convert the displacement into an electrical signal to be processed by a signal processing circuit to obtain displacement data. Thus, an induction signal can be generated when the first trigger 633 moves a corresponding distance from the second position to the first position. The use method of other structures as the induction module 63 is not described here.

[0156] In this embodiment, the movable member 631 is arranged opposite to the at least partial laser module 20 in the height direction; when the laser module 20 rises relative to the mounting shell 61 to reset to the original position, the laser module 20 can push the first trigger member 633 to rise, and when the laser module 20 moves to the preset original position, the movable member 631 is just moved to the first position to make the first trigger member 633 trigger the first sensing member 635 to send a sensing signal indicating that the laser module 20 has completed resetting, and the sensing signal is fed back to the controller to control the laser module 20 to stop moving. In this way, the laser module 20 can be more accurately controlled to reset to the original position. Since the first sensing member 635 and the first trigger member 633 of the position sensing module 63 are both located in the mounting shell 61, the dust and oil outside will not affect this part of the structure, so the performance of the position detection module 60 can be ensured stable, thereby ensuring that the position detection module 60 can accurately detect the state information of the laser module 20 when reaching the reset position and make feedback.

[0157] Since the first trigger member 633 and the first sensing member 635 are both arranged in the mounting cavity 613, they will not be contaminated and disturbed by dust, oil and other impurities outside, thereby reducing the risk of detection failure or false triggering and ensuring the stable performance and detection accuracy of the position detection module 60.

[0158] Please refer to Figure 16 and Figure 16 In some embodiments of the present application, the first reset member 65 is an elastic member arranged between the movable member 631 and the cavity wall of the mounting cavity 613 along the moving direction of the first trigger member 633, and the elastic member is in a compressed state when the movable member 131 is in the second position.

[0159] In this embodiment, the first reset member 65 can be a spring, a gas spring, an elastic air bag or the like, which can be arranged on the side of the top wall opposite to the first through hole 614 and located between the top wall and the movable member 631. When the movable member 631 is in the second position, the elastic member is in a compressed state to apply an elastic pushing force to the movable member 631 towards the side of the first through hole 614, so that the movable member 631 has a tendency to move from the first position to the second position and remain in the second position.

[0160] In some embodiments, the elastic member can also be arranged on the cavity wall with the first through hole 614 and connected with the movable member 631. When the movable member 631 is in the second position, the elastic member is in a stretched state and applies an elastic pulling force to the movable member 631, which can also make the movable member 631 have a tendency to move from the first position to the second position and remain in the second position.

[0161] Specifically, when the movable element 631 is not subjected to external force, the movable element 631 is subjected to the elastic force of the elastic element and is in the second position; during the movement of the movable element 631 into the mounting cavity 613 under the external force to move to the first position, the elastic element is subjected to elastic deformation and generates an elastic force in the opposite direction of the external force; when the external force acting on the movable element 631 is removed, the elastic element restores its shape and moves the movable element 631 to the second position.

[0162] Please refer to Figure 17 and Figure 16 In some embodiments of the present application, the mounting shell 61 has a top wall opposite to the first through hole 614, and the end of the movable element 631 facing the top wall is provided with a limiting column 6315, and the elastic element is sleeved on the limiting column 6315.

[0163] In the present embodiment, the mounting shell 61 has a top wall opposite to the first through hole 614, and the elastic element is arranged between the top wall of the mounting cavity 613 and the movable element 631, at this time, the elastic element applies an elastic pushing force to the movable element 631 towards the side of the first through hole 614.

[0164] Meanwhile, the end of the movable element 631 facing the top wall is provided with a limiting column 6315, which can be integrally formed with the movable element 631, or can be detachably or non-detachably connected with the movable element 631. In addition, the elastic element is sleeved on the limiting column 6315, for example, a spring is sleeved on the limiting column 6315, or an elastic air bag is arranged as a ring-shaped inflatable ring to be sleeved on the limiting column 6315; or the piston rod of the gas spring is arranged as a hollow rod to be sleeved on the limiting column 6315. In this way, the position stability of the elastic element can be improved, the elastic element can be prevented from being deviated, the elastic element can be ensured to stably act on the movable element 631, and the overall structural stability and performance stability of the position sensor can be ensured.

[0165] Please refer to Figure 17 and Figure 16 In some embodiments of the present application, the end of the movable element 631 facing the top wall is provided with a limiting hole 6317, and part of the limiting column 6315 is inserted into the limiting hole 6317; or, the limiting column 6315 is integrally formed with the movable element 631.

[0166] In this embodiment, the limiting column 6315 can be integrally formed with the movable piece 631. In this way, the limiting column 6315 and the movable piece 631 have high connection strength, the relative position between the limiting column 6315 and the movable piece 631 is stable, and the overall structural stability is improved. In some embodiments, the limiting column 6315 can also be detachably connected with the movable piece 631. When the limiting column 6315 is detachably connected with the movable piece 631, a limiting hole 6317 can be formed at the end of the movable piece 631 away from the first through hole 614, and part of the limiting column 6315 is inserted into the limiting hole 6317. In this way, the connection strength between the limiting column 6315 and the movable piece 631 can also be improved, so that the limiting column 6315 is not easy to be separated from the movable piece 631, thereby ensuring that the elastic piece stably acts on the movable piece 631 and improving the overall structural stability. In addition, the end of the elastic piece facing the movable piece 631 can also be inserted into the limiting hole 6317 to further limit the elastic piece. Of course, a counterbore hole 6319 can also be formed on the end face of the movable piece 631, a limiting hole 6317 is formed on the bottom wall of the counterbore hole 6319, and the end of the elastic piece is inserted into the counterbore hole 6319 and abuts against the bottom wall of the counterbore hole 6319. One end of the limiting column 6315 is inserted into the counterbore hole 6319 and inserted into the limiting hole 6317.

[0167] In addition, in some embodiments, the limiting column 6315 can be inserted into the cavity wall of the mounting cavity 613 opposite to the first through hole 614, thereby providing auxiliary positioning and limiting effect for the movable piece 631 and avoiding the deflection of the movable piece 631. At this time, the connection strength between the limiting column 6315 and the movable piece 631 is improved and the relative position between the limiting column 6315 and the movable piece 631 is stable, thereby avoiding the problem that the limiting column 6315 interferes with the movement of the movable piece 631 due to the deflection of the limiting column 6315.

[0168] Please refer to Figure 16 In some embodiments of the present application, the mounting shell 61 is provided with a second through hole 615 opposite to the first through hole 614, and the two ends of the movable piece 631 are movably inserted into the second through hole 615 and the first through hole 614, respectively.

[0169] In the embodiment, the second through hole 615 can be arranged opposite to the first through hole 614 in the mounting shell 61, for example, the second through hole 615 is arranged on the top wall opposite to the first through hole 614, or a limiting plate is arranged in the mounting cavity 613, and the second through hole 615 is arranged in the limiting plate. One end of the movable element 631 in the mounting cavity 613 is inserted into the second through hole 615. In this way, the first through hole 614 and the second through hole 615 arranged opposite to each other provide positioning and limiting effects for the movable element 631 at different positions in the length direction of the movable element 631, so as to avoid the movable element 631 from being deflected and to enable the movable element 631 to stably move to the first position or the second position.

[0170] In the embodiment, the second through hole 615 can be arranged opposite to the first through hole 614 in the mounting shell 61, for example, the second through hole 615 is arranged on the top wall opposite to the first through hole 614, or a limiting plate is arranged in the mounting cavity 613, and the second through hole 615 is arranged in the limiting plate. One end of the movable element 631 in the mounting cavity 613 is inserted into the second through hole 615. In this way, the first through hole 614 and the second through hole 615 arranged opposite to each other provide positioning and limiting effects for the movable element 631 at different positions in the length direction of the movable element 631, so as to avoid the movable element 631 from being deflected and to enable the movable element 631 to stably move to the first position or the second position.

[0171] Please refer to Figure 17 and Figure 18 In some embodiments of the present application, the movable element 631 comprises a stop portion 6311 and a plug-in portion 6313 connected to each other, the plug-in portion 6313 is arranged through the first through hole 614, and the stop portion 6311 is arranged in the mounting cavity 613. When the first trigger element 633 is arranged at the second position, the stop portion 6311 abuts against the cavity wall in which the first through hole 614 is arranged. The first trigger element 633 or the first sensing element 635 is arranged on the stop portion 6311. The first reset element 65 is connected between the stop portion 6311 and the mounting shell 61.

[0172] In the embodiment, the movable element 631 comprises a stop portion 6311 and a plug-in portion 6313 connected to each other. The width of the stop portion 6311 in at least one direction perpendicular to the length direction of the movable element 631 is greater than the width of the plug-in portion 6313 and the first through hole 614 in the direction. In this way, the plug-in portion 6313 is arranged through the first through hole 614, and the stop portion 6311 is arranged in the mounting cavity 613. When the movable element 631 is not subjected to other external forces, the first reset element 65 applies an outward moving force to the movable element 631. Since the stop portion 6311 cannot pass through the first through hole 614, the stop portion 6311 abuts against the cavity wall in which the first through hole 614 is arranged. Therefore, the movable element 631 can be limited at the second position, and the movable element 631 is prevented from falling out of the mounting cavity 613 completely. At this time, the first trigger element 633 or the first sensing element 635 of the sensing module 63 is arranged on the stop portion 6311. Therefore, the first sensing element 635 or the first trigger element 633 arranged on the movable element 631 can always be kept in the mounting cavity 613, and the first sensing element 635 or the first trigger element 633 arranged on the movable element 631 is prevented from being affected by foreign matters.

[0173] Please refer to Figure 17 In some embodiments of the present application, the mounting cavity 613 is provided with a positioning structure 616, which forms a positioning area 6161 in the mounting cavity 613, and part of the movable element 631 is limitedly mounted in the positioning area 6161.

[0174] In the present embodiment, the positioning structure 616 is arranged in the mounting cavity 613, which can divide the mounting cavity 613 into a positioning area 6161 for mounting the movable element 631; wherein the positioning area 6161 can be completely enclosed by the positioning structure 616, for example, the positioning structure 616 is arranged as a surrounding edge along the circumference of the movable element 631 or at least two positioning elements are arranged along the circumference of the movable element 631; the positioning area 6161 can also be formed by the positioning structure 616 and the cavity wall of the mounting cavity 613. Arranging part of the movable element 631 in the positioning area 6161 can also prevent the movable element 631 from being deflected, so that the movable element 631 can stably move to the first position or the second position, and the detection accuracy of the position detection module 60 is improved.

[0175] Please refer to Figure 16 In some embodiments of the present application, the first sensing element 635 has a transmitting portion 6351 and a receiving portion 6353 arranged opposite to each other, and the first triggering element 633 is a shielding structure; when the movable element 631 is in the first position, the first triggering element 633 is located between the transmitting portion 6351 and the receiving portion 6353, so as to block the signal path between the transmitting portion 6351 and the receiving portion 6353.

[0176] In the present embodiment, the sensing module 63 includes a transmitting portion 6351 and a receiving portion 6353 arranged opposite to each other, and the first triggering element 633 is arranged as a shielding structure and can enter and exit between the transmitting portion 6351 and the receiving portion 6353 when the movable element 631 moves between the first position and the second position, so as to block the signal path between the transmitting portion 6351 and the receiving portion 6353 and hinder the receiving portion 6353 from receiving the signal sent by the transmitting portion 6351. Among them, the normal state can be that the receiving portion 6353 normally receives the signal sent by the transmitting portion 6351, at this time, the movable element 631 is in the second position, and the first triggering element 633 is located outside the transmitting portion 6351 and the receiving portion 6353; the trigger state can be that the receiving portion 6353 cannot receive the signal sent by the transmitting portion 6351, at this time, the movable element 631 is in the first position, and the first triggering element 633 is arranged between the transmitting portion 6351 and the receiving portion 6353; in this way, when the receiving portion 6353 cannot normally receive the signal sent by the transmitting portion 6351, the first sensing element 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or has moved to a preset position.

[0177] In addition, the receiving portion 6353 can be in a normal state when it fails to receive the signal sent by the sending portion 6351, and in this case, the movable member 631 is in the second position, and the first trigger member 633 is arranged between the sending portion 6351 and the receiving portion 6353. The receiving portion 6353 can be in a trigger state when it normally receives the signal sent by the sending portion 6351, and in this case, the movable member 631 is in the first position, and the first trigger member 633 is located outside the sending portion 6351 and the receiving portion 6353. In this way, when the receiving portion 6353 normally receives the signal sent by the sending portion 6351, the first sensing member 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or has moved to a preset position.

[0178] In this embodiment, the first sensing member 635 can be an optical switch, and the sending portion 6351 can send an optical signal to the receiving portion 6353. For example, the receiving portion 6353 can be in a normal state when it receives the optical signal, and in this case, the receiving portion 6353 fails to receive the optical signal sent by the sending portion 6351. When the receiving portion 6353 fails to normally receive the optical signal sent by the sending portion 6351, the first sensing member 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or has moved to a preset position.

[0179] In addition, the receiving portion 6353 can also be a Hall sensor, the sending portion 6351 can be a magnet 53, and the first trigger member 633 can be a magnetic shielding member. When the first trigger member 633 is arranged between the sending portion 6351 and the receiving portion 6353, the Hall sensor fails to sense a magnetic field or senses a magnetic field with a weak intensity. The receiving portion 6353 can be in a normal state when the Hall sensor senses a strong magnetic field, and in this case, the first trigger member 633 is located outside the sending portion 6351 and the receiving portion 6353. The receiving portion 6353 can be in a trigger state when the first trigger member 633 is arranged between the sending portion 6351 and the receiving portion 6353, and the Hall sensor senses a magnetic field with a weak intensity or fails to sense a magnetic field. When the Hall sensor senses a magnetic field with a weak intensity or fails to sense a magnetic field, the first sensing member 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or has moved to a preset position.

[0180] Of course, the first sensing member 635 can also be of other structural types, such as a microwave sensor, and the like, which will not be described herein.

[0181] Please refer to Figure 17 and Figure 16 In some embodiments of the present application, the first trigger member 633 is arranged on the movable member 631, and the first sensing member 635 is connected to the mounting shell 61.

[0182] In the embodiment, the first trigger 633 can be connected to the movable member 631 or integrally arranged with the movable member 631. It can be understood that the first sensor 635 is an electronic device, which usually needs power supply and feedback of sensing signals. In some embodiments, the first sensor 635 can be provided with a power supply and feedback of sensing signals through wireless transmission. In some embodiments, the first sensor 635 needs to be connected with a wire for receiving power supply and feedback of sensing signals, or the first sensor 635 is arranged on the circuit board 67 in the following embodiment. Therefore, in the embodiment, the first sensor 635 is fixed in the mounting cavity 613, and the first trigger 633 is arranged on the movable member 631 and moves with the movable member 631. In this way, the first sensor 635 is prevented from moving to pull the wire connected with the first sensor 635, thereby reducing the risk of breakage or damage of the wire, improving the stability of electrical connection of the first sensor 635, and ensuring the performance stability of the position detection module 60.

[0183] Please refer to Figure 17 and Figure 15 In some embodiments of the present application, the position detection module 60 further comprises a circuit board 67 arranged in the mounting cavity 613, the first sensor 635 is arranged on the circuit board 67 and electrically connected with the circuit board 67, and the first trigger 633 is arranged on the movable member 631.

[0184] In the embodiment, the position detection module 60 further comprises a circuit board 67 arranged in the mounting cavity 613, the first sensor 635 is arranged on the circuit board 67 and electrically connected with the circuit board 67, and the first trigger 633 is arranged on the movable member 631.

[0185] Please refer to Figure 17 and Figure 19 In some embodiments of the present application, the mounting shell 61 is provided with a connecting port 617 communicating with the mounting cavity 613, and the circuit board 67 is provided with a connecting seat 671 facing the connecting port 617.

[0186] In the embodiment, the connecting port 617 is formed on the mounting shell 61 to communicate with the mounting cavity 613, and the connecting seat 671 for plugging the power line and the signal line is arranged on the circuit board 67, and the power line and the signal line can be integrated into the same wire. In this way, the wire or the plug-in seat matched with the connecting seat 671 can be arranged in the connecting port 617 to be connected with the connecting seat 671, so that the circuit board 67 can be powered and signal transmission with the circuit board 67 can be realized.

[0187] Please refer to Figures 19 to 25 In some embodiments of the present application, the laser 100 further comprises a distance measuring module 70, which is arranged in the laser module 20, and is used to detect the distance between the laser module 20 and the processing position.

[0188] In the embodiment, the laser module 20 is liftable so that the height of the laser module 20 can be adjusted to process the processing position with different heights. In the embodiment, the distance measuring module 70 is arranged in the laser 100, which can be used to detect the distance between the focal point of the laser module 20 and the surface of the processing object. The distance measuring module 70 can be an ultrasonic distance measuring structure, an optoelectronic distance measuring structure, a laser distance measuring structure or a contact distance measuring structure, etc. The ultrasonic distance measuring, the optoelectronic distance measuring and the laser distance measuring can be respectively used to calculate the distance by the propagation time of the sound wave, the infrared light and the laser, and the contact distance measuring structure can be used to calculate the distance by the falling distance when the distance measuring module 70 falls until abutting with the processing position.

[0189] Please refer to Figure 22 In some embodiments of the present application, the distance measuring module 70 comprises a shell 71, a circuit board 72, a thimble 73 and a detection mechanism 74. The shell 71 is internally provided with a containing cavity 713, a first opening and a second opening which are communicated with the containing cavity 713. The circuit board 72 is arranged in the first opening. The thimble 73 extends downward from the bottom wall of the containing cavity 713 and is liftable through the second opening and partially located in the containing cavity 713. The thimble 73 has a starting position and a trigger position above the starting position. The detection mechanism 74 is arranged in the containing cavity 713 and comprises a second trigger 741 and a second inductor 742. The second trigger 741 is connected with the thimble 73, and the second inductor 742 is arranged on the surface of the circuit board 72 facing the containing cavity 713 and is electrically connected with the circuit board 72. When the thimble 73 is in the trigger position, the second trigger 741 triggers the second inductor 742.

[0190] In the embodiment, the distance measuring module 70 is located at the side of the laser module 20 and is arranged close to the light outlet 23, so that the distance between the to-be-processed position below the light outlet 23 and the laser module 20 can be measured more accurately. The distance measuring module 70 is composed of a shell 71, a circuit board 72, a top pin 73 and a detection mechanism 74. The shell 71 and the circuit board 72 enclose a sealed accommodating cavity 713. The circuit board 72 is exposed on the surface of the accommodating cavity 11 and can be provided with a terminal seat 721 for connecting a power supply and a control system. The top pin 73 extends along the lifting direction of the laser module 20 and has one end penetrating out of the bottom of the accommodating cavity 713, so that the top pin 73 can be lifted and has a starting position and a trigger position above the starting position. The detection mechanism 74 is arranged in the accommodating cavity 11. A second trigger piece 741 of the detection mechanism 74 is connected with the top pin 73, and a second sensing piece 742 of the detection mechanism 74 is arranged on the circuit board 72 and is electrically connected with the circuit board 72, so that the detection mechanism 74 is prevented from being polluted by smoke and oil stains during the processing. The second trigger piece 741 of the detection mechanism 74 is connected with the top pin 73 arranged in the accommodating cavity 713, so as to switch between the starting position and the trigger position along with the lifting of the top pin 73. Under the action of gravity or the second reset piece 75 in the following embodiment, the top pin 73 can fall to the starting position under the action of gravity or the second reset piece 75 in the following embodiment. When distance measurement is needed, the laser module 20 is controlled to be lowered so that the distance measuring module 70 is lowered together. After the top pin 73 abuts against the to-be-processed position, the laser module 20 and the distance measuring module 70 are further lowered so that the top pin 73 is retracted into the accommodating cavity 713 and then rises to the trigger position. The second trigger piece 741 triggers the second sensing piece 742. After the second sensing piece 742 generates an induction signal, the induction signal can be transmitted to the control system through the circuit board 72. At this time, the distance between the focal point of the laser module 20 or the light outlet and the to-be-processed position can be calculated by obtaining the lowering distance of the laser module 20. After the second sensing piece 742 is triggered, the laser module 20 can be controlled to move upward by a fixed distance. The distance is the distance between the lower end surface of the top pin 73 in the trigger position and the focal point of the laser module 20, so as to ensure that the focal point of the laser module 20 falls on the to-be-processed position and improve the processing precision.

[0191] The second sensing member 742 can be a Hall sensor, a photoelectric switch, a proximity switch, a grating reading head, etc. For example, the second sensing member 742 is a Hall sensor, and the second triggering member 741 is a magnet. When the second triggering member 741 moves with the ejector pin 73 between the trigger position and the starting position, the magnetic field strength around the Hall sensor changes, for example, from weak to strong or from strong to weak. The Hall sensor detects the magnetic field strength when the second triggering member 741 is in the trigger position as the trigger condition, so that the Hall sensor can send a sensing signal when the second triggering member 741 reaches the trigger position. If the proximity switch is used as the second sensing member 742, the second triggering member 741 can touch the sensing surface of the proximity switch when the ejector pin 73 is in the trigger position, so that the proximity switch sends a sensing signal. If the grating reading head is used as the second sensing member 742, and the second triggering member 741 is a scale grating extending along the moving direction of the ejector pin 73. When the ejector pin 73 moves from the starting position to the trigger position, the scale grating moves relative to the grating reading head. The grating reading head can read the displacement of the relative movement of the scale grating, and convert the displacement into an electrical signal to be processed by a signal processing circuit to obtain displacement data. Thus, the grating reading head can send a sensing signal when the second triggering member 741 moves a corresponding distance from the starting position to the trigger position. The use of other structures as the detection mechanism 74 will not be described here.

[0192] Optionally, the shell 71 is provided with a limiting notch 719, and at least part of the structure of the circuit board 72 is arranged in the limiting notch 719 to limit the circuit board 72 and improve the installation stability of the circuit board 72.

[0193] Please refer to Figure 22 In some embodiments of the present application, the distance measuring module 70 further comprises a second reset member 75 arranged in the accommodating cavity 713 and acting between the shell 71 and the ejector pin 73 to make the ejector pin 73 have a tendency to be kept in the starting position.

[0194] In this embodiment, the second reset member 75 is arranged in the distance measuring module 70. The second reset member 75 can be an elastic member such as a spring, a gas spring, an elastic air bag, etc. The elastic member can be arranged on the side of the top wall opposite to the second opening and apply an elastic pushing force to the stylus 73 towards the side of the second opening, so that the stylus 73 has a tendency to move from the trigger position to the response position and remain in the response position. The elastic member can also be arranged on the cavity wall provided with the second opening and connected with the stylus 73 to apply an elastic pulling force to the stylus 73, so that the stylus 73 also has a tendency to move from the trigger position to the response position and remain in the response position. The second reset member 75 can also be a magnetic structure. The magnetic structure can include a first magnetic member and a second magnetic member arranged on the stylus 73 and the housing 71 respectively. The first magnetic member and the second magnetic member can have a magnetic attraction force therebetween, so that the stylus 73 has a tendency to move from the trigger position to the response position and remain in the response position. The first magnetic member and the second magnetic member can also have a magnetic repulsion force therebetween, which can be used to push the stylus 73 to have a tendency to move from the trigger position to the response position and remain in the response position. When the stylus 73 is moved into the mounting cavity 613 by an external force, the action force applied by the second reset member 75 can be overcome. When the external force acting on the stylus 73 is removed, the action force applied by the second reset member 75 to the stylus 73 can move the stylus 73 to the response position. In this way, the stylus 73 can be stably kept in the starting position without needing to abut against the to-be-processed position, and a downward action force can be applied to the stylus 73 to avoid the stylus 73 from bouncing upward due to the reaction force when initially contacting the to-be-processed position, thereby causing the second sensing member 742 to be mistakenly triggered.

[0195] Please refer to Figure 23 and Figure 23 In some embodiments of the present application, the second trigger member 741 includes a fixed part 7411 and a trigger part 7412. The fixed part 7411 is sleeved on and fixed to the stylus 73. The trigger part 7412 is connected to one end of the fixed part 7411 close to the circuit board 72 and extends upward. In this way, the mounting position of the electronic devices such as the circuit board 72 can be as far away from the light outlet 23 of the laser module 20 as possible, thereby being far away from the processing position and the laser, avoiding dust and other impurities from adhering to the electronic devices such as the circuit board 72, and avoiding the heat generated during the processing process from affecting the performance of the electronic devices.

[0196] Please refer to Figures 21 to 23In some embodiments of the present application, the second trigger 741 is provided with a threaded hole 7413, and at least part of the outer surface of the ejector pin 73 is provided with external threads. The threaded hole 7413 is matched with the external threads to threadedly connect the trigger 741 with the ejector pin 73. In this way, the second trigger 741 and the ejector pin 73 can be easily disassembled, and the installation height of the second trigger 741 on the ejector pin 73 can be adjusted, so as to adjust the distance between the starting position and the triggering position of the ejector pin 73, to adapt to different processing requirements.

The mounting surface of the back plate 210 is recessed with a fixing groove 21f, the air path interface 21b is arranged on the groove bottom wall of the fixing groove 21f, and the sealing ring 21d is arranged in the fixing groove 21f and surrounds the air path interface 21b, so as to limit the position of the sealing ring 21d by the fixing groove 21f, avoid the sealing ring 21d from being deviated and unable to surround the air path interface 21b and the outer circumference of the mounting port 13, and ensure that part of the sealing ring 21d protrudes from the fixing groove 21f, so that the laser 100 can abut against the sealing ring 21d when the laser 100 is mounted on the mounting surface, and the sealing performance is good.
