[0042] The utility model provides a laser 100 .

[0043] Combined with reference Figures 1 to 4In some embodiments of the present application, the laser 100 includes a shell 10, a laser module 20 and a heat dissipation module 30. The shell 10 includes an outer shell 11 and a surrounding wall 13. A heat dissipation cavity 113 is formed in the outer shell 11. The surrounding wall 13 is arranged in the heat dissipation cavity 113, and a receiving cavity 133 is separated in the heat dissipation cavity 113. The receiving cavity 133 is connected to the heat dissipation cavity 113; at least part of the laser module 20 is arranged in the receiving cavity 133, and the light output head 223 of the laser module 20 faces the outside of the shell 11; at least part of the heat dissipation module 30 is arranged in the heat dissipation cavity 113.

[0044] The laser 100 of the present application can be a laser processing head in laser processing equipment such as a laser engraving machine, a laser cutting machine, a laser marking machine, etc., or a laser ranging or positioning structure for emitting laser in equipment such as laser ranging or positioning. Among them, the laser 100 includes a shell 10, a laser module and a heat dissipation module 30; the shell 10, as the installation base of the laser 100, can be made of a material with good heat dissipation performance, so as to facilitate the heat transfer and heat dissipation of the internal components to the outside. Specifically, the shell 10 includes a shell 11 and a surrounding wall 13 arranged in the shell 11, and a heat dissipation cavity 113 is formed in the shell 11. The surrounding wall 13 separates a receiving cavity 133 in the heat dissipation cavity 113, and makes the receiving cavity 133 communicate with the heat dissipation cavity 113, and an outlet connecting the receiving cavity 133 and the heat dissipation cavity 113 is opened on the shell 11. The laser module 20 is a structure in the laser 100 for generating and emitting laser light, and may include only a laser generator 21, or may include a flying optical path structure 22 for guiding the laser emission path and shaping the laser; so that at least part of the laser module 20 is arranged in the accommodating cavity 133, for example, the entire laser module 20 may be limitedly installed in the accommodating cavity 133, or only the laser generator 21 may be limitedly installed in the accommodating cavity 133, and the light output head 223 of the laser module 20 is arranged toward the outlet opened on the outer shell 11, and the light output head 223 may be located in the outer shell 11, or may be arranged through the outlet and protrude from the outer shell 11, so that the laser generated by the laser module 20 can be emitted from the light output head 223.

[0045] At least part of the heat dissipation module 30 is arranged in the heat dissipation cavity 113 to dissipate heat for the components in the housing 11. Specifically, the heat dissipation module 30 can be a water-cooled heat dissipation structure, which can include a radiator and a water-cooled pipeline. The radiator can be a water tank or other heat dissipation structures, so that at least part of the water-cooled pipeline is passed through the heat dissipation cavity 113, and the other part of the water-cooled pipeline is connected to the radiator, so that the heat in the housing 11 can be taken away by the refrigerant in the water-cooled pipeline. The radiator can quickly dissipate the heat brought out by the refrigerant, so that the refrigerant flowing back to the water-cooled pipeline in the heat dissipation cavity 113 maintains a relatively low temperature. The heat dissipation module 30 can also be an air-cooled module to drive the airflow to dissipate heat for the components in the housing 11 and take away the heat. The heat dissipation module 30 can also be a heat dissipation tooth 32 arranged on the surrounding wall 13, which is used to increase the heat dissipation area of ​​the accommodating cavity 133 to dissipate heat outward, which can also improve the heat dissipation efficiency and avoid heat accumulation. In addition, in some embodiments, the heat dissipation module 30 may also be other heat dissipation structures, or a combination of any two or more of the aforementioned heat dissipation structures, both of which can improve the heat dissipation efficiency of the laser 100 and reduce the risk of damage to the laser module 20 and the laser 100.

[0046] Therefore, it can be understood that the technical solution of the present application is to set a receiving cavity 133 for installing at least part of the laser module 20 in the shell 10 of the laser 100, and a heat dissipation cavity 113 is formed outside the receiving cavity 133, at least part of the laser module 20 is set in the receiving cavity 133, and the heat dissipation module 30 in the heat dissipation cavity 113 is used to dissipate the heat of the laser module 20; such a setting can improve the heat dissipation capacity of the laser 100, so that the heat of the laser module 20 is dissipated through the surrounding wall 13 and the heat dissipation module 30, thereby reducing the risk of damage to the laser module 20 and the laser 100.

[0047] Combined with reference Figures 2 to 4 In some embodiments of the present application, the heat dissipation cavity 113 includes a first cavity 1131 and a second cavity 1132 arranged side by side along a first direction, the heat dissipation module 30 and the surrounding wall 13 are both arranged in the first cavity 1131, and an opening connecting to the second cavity 1132 is provided at one end of the accommodating cavity 133 facing the second cavity 1132; the laser module 20 includes a laser generator 21 and a flying optical path structure 22, the laser generator 21 is arranged in the accommodating cavity 133 and faces the second cavity 1132, at least part of the flying optical path structure 22 is arranged in the second cavity 1132, and a light emitting head 223 protruding from the outer shell 11 is provided.

[0048] In this embodiment, the heat dissipation cavity 113 includes a first cavity 1131 and a second cavity 1132 arranged side by side along a first direction, the heat dissipation module 30 and the surrounding wall 13 are both arranged in the first cavity 1131, and the laser generator 21 for generating laser in the laser module 20 is limitedly installed in the accommodating cavity 133 formed by the surrounding wall 13. Among them, the laser module 20 also includes a flying optical path structure 22, which is arranged in the second cavity 1132. A focusing mirror can be arranged in the flying optical path structure 22 to shape the laser emitted by the laser generator 21, so that the laser is concentrated and focused, and the energy density of the laser spot is increased. In some embodiments, the flying optical path structure 22 can also be provided with a reflector 221, etc., which can be used to control the propagation path and emission direction of the laser.

[0049] Usually in the laser module 20, the main component that generates heat is the laser generator 21. In this embodiment, the structure in the laser 100 is reasonably arranged, and the laser generator 21 is set in the first chamber 1131 near the heat dissipation module 30, so that the heat generated by the laser generator 21 during operation can be quickly discharged to avoid heat accumulation.

[0050] Combined with reference Figure 2 and Figure 6 In some embodiments of the present application, an air inlet 114 is provided at one end of the first chamber 1131 away from the second chamber 1132, the surrounding wall 13 is spaced apart from the air inlet 114, and an air flow inlet 134 is provided at one end of the accommodating cavity 133 away from the second chamber 1132;

[0051] The heat dissipation module 30 includes a heat dissipation fan 31, which is arranged at one end of the first chamber 1131 away from the second chamber 1132, and part of the heat dissipation fan 31 is arranged between the air inlet 114 and the surrounding wall 13, and the air outlet of the heat dissipation fan 31 is arranged toward the first chamber 1131 and the accommodating cavity 133.

[0052] In this embodiment, the heat dissipation module 30 is an air-cooled heat dissipation structure, including a heat dissipation fan 31 for driving air flow. Specifically, the housing 11 can be provided with an end cover at one end of the first chamber 1131 away from the second chamber 1132, and an air inlet 114 can be opened on the end cover, or the end of the first chamber 1131 away from the second chamber 1132 can be directly penetrated as the air inlet 114, and the surrounding wall 13 and the air inlet 114 are arranged at intervals, and an air flow inlet 134 is arranged at one end of the accommodating chamber 133 facing the air inlet 114; the heat dissipation fan 31 is arranged at the air inlet 114, and part of the air outlet of the heat dissipation fan 31 is arranged toward the air flow inlet 134; in this way, the heat dissipation fan 31 can drive the air flow into the first chamber 1131 and the accommodating chamber 133, and then into the second chamber 1132, so that the air flow can take away the heat in the accommodating chamber 133 and the heat dissipation chamber 113 and flow to the outside. The housing 11 can be composed of at least two parts to form a non-sealed structure, so that the cooling fan 31 drives the airflow entering the housing 11 to flow out from the gap between the two parts. Alternatively, at least one of the first cooling hole 115 and the second cooling hole 116 can be opened on the housing 11 in the following embodiments, which is not limited here.

[0053] Please refer to Figure 1 and Figure 5 In some embodiments of the present application, a first heat dissipation hole 115 is formed on the wall of the first chamber 1131;

[0054] And / or, a vent 1133 is provided between the first chamber 1131 and the second chamber 1132 , and a second heat dissipation hole 116 is provided at one end of the second chamber 1132 away from the first chamber 1131 .

[0055] In this embodiment, a first heat dissipation hole 115 may be provided on the bottom wall of the first chamber 1131. When the heat dissipation fan 31 drives the airflow into the first chamber 1131 and the accommodating chamber 133, the airflow may be discharged outward from the first heat dissipation hole 115 on the cavity wall of the first chamber 1131. In addition, the first chamber 1131 may be connected to the second chamber 1132, and a second heat dissipation hole 116 may be provided at one end of the second chamber 1132 away from the first chamber 1131, so that the airflow may flow outward through the first chamber 1131 and the second chamber 1132 in sequence, thereby taking away the heat of the laser 100 and improving the heat dissipation efficiency.

[0056] In some embodiments, a first heat dissipation hole 115 may be opened in the wall of the first chamber 1131, and a second heat dissipation hole 116 may be opened in the second chamber 1132, so that airflow can flow through various positions in the laser 100 and be discharged from the first heat dissipation hole 115 and the second heat dissipation hole 116 respectively, thereby improving heat dissipation efficiency.

[0057] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the housing 11 includes a first shell 111 and a second shell 112 connected to each other. The first shell 111 is provided with a first chamber 1131 , and the second shell 112 is provided with a second chamber 1132 .

[0058] In this embodiment, the housing 11 includes a first shell 111 and a second shell 112 connected to each other, wherein a first chamber 1131 is formed in the first shell 111 and provided with a surrounding wall 13; a second chamber 1132 is formed in the second shell 112 for installing the flying optical path structure 22 of the laser module 20. With such an arrangement, the laser 100 can be formed into a modular structure, so that the laser generator 21 and the heat dissipation structure can be first installed with the first shell 111 to form an integral structure, the flying optical path structure 22 is combined with the second shell 112 to form an integral structure, and then the first shell 111 and the second shell 112 can be assembled, thereby improving the convenience of assembly and avoiding the need to dismantle the entire laser 100 when disassembling and assembling part of the structure in the laser 100 for maintenance.

[0059] Please refer to Figure 2 In some embodiments of the present application, the flying optical path structure 22 includes a reflector 221 and a focusing structure 222. The reflector 221 is arranged on the light-emitting side of the laser generator 21, so that the laser emitted by the laser generator 21 is reflected and propagates along the second direction, and the second direction is perpendicular to the first direction; the focusing structure 222 is arranged on the light-emitting side of the reflector 221 and extends along the second direction. A light-emitting head 223 is provided at the end of the focusing structure 222 away from the reflector 221.

[0060] In this embodiment, the flying optical path structure 22 includes a reflector 221 and a focusing structure 222. The reflector 221 is used to change the propagation direction of the laser emitted by the laser generator 21, so that the laser propagates along the first direction and changes to propagating along the second direction, and is injected into the focusing structure 222 for focusing, thereby increasing the energy density of the light spot. In this arrangement, the propagation direction of the laser is changed by the reflector 221, thereby avoiding the laser 100 and the focusing structure 222 being arranged in the same straight line direction, which results in the laser 100 structure being longer.

[0061] In some embodiments of the present application, the light focusing structure 222 is movably disposed along the second direction.

[0062] The laser 100 in the embodiment of the present application can be used in laser processing equipment such as laser engraving, laser cutting, laser marking, and laser welding, and in some embodiments, the light output head 223 of the laser module 20 is connected to a blowing structure for dust removal. In this embodiment, the focusing structure 222 is movable in the laser emission direction, i.e., the second direction, so that the light output head 223 of the focusing structure 222 can be raised and lowered according to the height of the processing position, thereby avoiding the light output head 223 being too far from the processing position, resulting in the airflow used for dust removal at the position of the light output head 223 failing to effectively remove dust from the processing position.

[0063] Please refer to Figure 4 and Figure 6 In some embodiments of the present application, the heat dissipation module 30 includes a plurality of heat dissipation teeth 32 , and the plurality of heat dissipation teeth 32 are arranged side by side on at least a portion of the surface of the surrounding wall 13 .

[0064] In this embodiment, a plurality of heat dissipation teeth 32 arranged side by side are arranged on at least part of the surface of the surrounding wall 13. For example, in the following embodiment, the surrounding wall 13 includes a first plate body 131 and a second plate body 132. The heat dissipation teeth 32 can be arranged on the surface of the first plate body 131 or the second plate body 132, or on the surface of the first plate body 131 and the second plate body 132. The arrangement of the heat dissipation teeth 32 increases the heat dissipation area of ​​the surrounding wall 13, so that the heat in the accommodating cavity 133 can be dissipated more quickly through the large-area heat dissipation teeth 32 after being transferred to the surrounding wall 13, thereby improving the heat dissipation efficiency.

[0065] In some embodiments, the heat dissipation module 30 also includes a heat dissipation fan 31, and the arrangement direction of the plurality of heat dissipation teeth 32 may be approximately perpendicular to the airflow direction of the heat dissipation fan 31, thereby forming an airflow channel between two adjacent heat dissipation teeth 32 to reduce the obstruction of the heat dissipation teeth 32 to the airflow, and allowing the airflow to fully contact each heat dissipation tooth 32, thereby better exchanging heat with the heat dissipation teeth 32 and taking away the heat of the heat dissipation teeth 32, thereby improving the heat dissipation efficiency.

[0066] In one embodiment of the present application, the heat dissipation module 30 includes a water-cooled heat dissipation structure, which at least includes a water-cooled pipeline disposed in the heat dissipation cavity 113 , and the water-cooled pipeline is attached to at least a portion of the surface of the surrounding wall 13 .

[0067] In this embodiment, the heat dissipation module 30 includes a water-cooled heat dissipation structure, which may include a radiator and a water-cooled pipeline. The radiator may be a water tank or other heat dissipation structures, so that at least part of the water-cooled pipeline is arranged in the heat dissipation cavity 113, and the other part of the water-cooled pipeline is connected to the radiator, so that the heat in the shell 11 can be taken away by the refrigerant in the water-cooled pipeline. The radiator can quickly dissipate the heat brought out by the refrigerant, so that the refrigerant flowing back to the water-cooled pipeline in the heat dissipation cavity 113 maintains a relatively low temperature, and then better absorbs the heat transferred from the heat dissipation cavity 113 and the accommodating cavity 133 to the surrounding wall 13, thereby improving the heat dissipation efficiency. In some embodiments, a heat dissipation tooth 32 may be arranged on at least part of the surface of the surrounding wall 13, and the heat dissipation tooth 32 may be arranged on the same surface of the surrounding wall 13 as the water-cooled pipeline, for example, the water-cooled pipeline is arranged in the heat dissipation tooth 32, or the water-cooled pipeline and the heat dissipation tooth 32 may be arranged on different surfaces of the surrounding wall 13, both of which can improve the heat dissipation efficiency.

[0068] Please refer to Figure 4 In some embodiments of the present application, the surrounding wall 13 is spaced apart from the bottom wall of the heat dissipation cavity 113 . The surrounding wall 13 is spaced apart from the bottom wall of the heat dissipation cavity 113 .

[0069] In this embodiment, the heat dissipation cavity 113 is defined to have a top wall and a bottom wall arranged opposite to each other, and a side wall for connecting the top wall and the bottom wall, so that the surrounding wall 13 is connected to the top wall of the heat dissipation cavity 113, and is spaced apart from the bottom wall of the heat dissipation cavity 113. In this way, a heat dissipation space is formed between the surrounding wall 13 and the bottom wall of the heat dissipation cavity 113, so that the heat in the accommodating cavity 133 can be better dissipated to the heat dissipation cavity 113, and the heat is dissipated through the heat dissipation module 30, thereby improving the heat dissipation efficiency. In addition, the lower part of the surrounding wall 13 can also be used as an installation space for installing other devices to improve space utilization.

[0070] Please refer to Figure 4 In some embodiments of the present application, the surrounding wall 13 is spaced apart from at least one side wall of the heat dissipation cavity 113 .

[0071] In this embodiment, the surrounding wall 13 can be spaced apart from at least part of the side wall, and a heat dissipation space can be formed between the surrounding wall 13 and the side wall of the heat dissipation cavity 113, so that the heat in the accommodating cavity 133 can be better dissipated into the heat dissipation cavity 113, and the heat is dissipated through the heat dissipation module 30, thereby improving the heat dissipation efficiency. In addition, the space between the surrounding wall 13 and the side wall can also be used as an installation space for installing other devices to improve space utilization. In addition, the surrounding wall 13 can also be spaced apart from the bottom wall and part of the side wall of the heat dissipation cavity 113.

[0072] Please refer to Figure 4 and Figure 6In some embodiments of the present application, the surrounding wall 13 includes a first plate body 131 and a second plate body 132, the first plate body 131 extends downward from the top wall of the accommodating cavity 133, the second plate body 132 extends from the lower end of the first plate body 131 to the side wall of the accommodating cavity 133 and is connected to the side wall, and the second plate body 132 is spaced apart from the bottom wall of the accommodating cavity 133.

[0073] Such an arrangement enables the surrounding wall 13 to be connected to the top wall and the side wall of the heat dissipation cavity 113 at the same time, thereby improving the connection strength between the surrounding wall 13 and the outer shell 11; and a heat dissipation space is formed between the first plate body 131 and the side wall of the heat dissipation cavity 113 and between the second plate body 132 and the bottom wall of the heat dissipation cavity 113, so that the heat in the accommodating cavity 133 can be better dissipated into the heat dissipation cavity 113, and the heat is dissipated through the heat dissipation module 30, thereby improving the heat dissipation efficiency.

[0074] Please refer to Figure 4 In some embodiments of the present application, the housing 10 further includes a supporting portion 15 , which extends from the surrounding wall 13 toward the bottom wall of the heat dissipation cavity 113 and is supported on the bottom wall of the heat dissipation cavity 113 .

[0075] In this embodiment, a support portion 15 is provided in the housing 10, one end of the support portion 15 abuts against the bottom wall of the heat dissipation cavity 113, and the other end abuts against the position, and is used to support the surrounding wall 13, improve the structural strength of the surrounding wall 13, and prevent the surrounding wall 13 from being deformed or broken by the pressure of the laser module 20 installed in the accommodating cavity 133. It can be understood that the support portion 15 can extend vertically downward from the bottom of the surrounding wall 13, or the support portion 15 can be extended obliquely from the surrounding wall 13 to the edge adjacent to the bottom wall, so as to avoid the setting of the surrounding wall 13 affecting the installation of other devices on the bottom wall, such as the ranging module 50 in the following embodiment, and improve the utilization rate of the space.

[0076] Please refer to Figure 3 In some embodiments of the present application, the laser 100 further includes a control board 40 , which is disposed in the heat dissipation cavity 113 and electrically connected to the laser module 20 , and the control board 40 is spaced apart from the surrounding wall 13 .

[0077] In this embodiment, the laser 100 further includes a control board 40 disposed in the heat dissipation cavity 113. The control board 40 may be a circuit board and may be integrated with electronic devices such as a processor and a controller. The control board 40 is electrically connected to the laser module 20 and may control and adjust the laser output. In some embodiments, a blowing structure for dust removal is provided in the laser 100. The control board 40 may also be used to control the opening and closing of the gas path and the size of the blowing, for example, a solenoid valve or other valve body structure of the blowing structure may be provided on the control board 40. In addition, the control board 40 may also be electrically connected to the heat dissipation module 30, for example, to the heat dissipation fan 31, to control the operating state of the heat dissipation fan 31.

[0078] By placing the control board 40 in the heat dissipation cavity 113, the heat dissipation module 30 can also dissipate heat for the control board 40 at the same time, thereby improving the heat dissipation efficiency. In addition, the control board 40 is spaced apart from the surrounding wall 13 to prevent the heat generated by the laser module 20 and the heat generated by the control board 40 from being transferred to each other through the surrounding wall 13, thereby affecting the heat dissipation efficiency. Instead, a heat dissipation space is formed between the control board 40 and the surrounding wall 13, thereby allowing both the laser module 20 and the control board 40 to dissipate heat quickly. In some embodiments, the heat dissipation module 30 is provided with a heat dissipation fan 31. At this time, the gap between the surrounding wall 13 and the control board 40 can also be used as an airflow channel to improve the heat dissipation efficiency.

[0079] Please refer to Figure 3 In some embodiments of the present application, a clearance opening 117 is provided on the bottom wall of the heat dissipation cavity 113 , and the laser 100 further includes a ranging module 50 , which is disposed on the bottom wall of the heat dissipation cavity 113 , and a probe 51 of the ranging module 50 is exposed at the clearance opening 117 .

[0080] In this embodiment, a distance measuring module 50 may be further provided in the laser 100. The distance measuring module 50 may be an ultrasonic distance measuring device, a laser distance measuring device, a contact probe distance measuring device or other structures. The distance measuring module 50 may only include a distance measuring component, or may include a circuit board and other structures for controlling the operation of the distance measuring component and receiving, processing and transmitting detection signals, etc. The distance measuring module 50 may be provided on the bottom wall of the heat dissipation cavity 113, and a avoidance opening 117 may be provided on the bottom wall of the heat dissipation cavity 113, so that the probe 51 of the distance measuring module 50 is provided toward the avoidance opening 117 or extends outward from the avoidance opening 117, so as to be exposed at the position of the avoidance opening 117, so as to be used for detecting the distance between the laser 100 and the processing position.

[0081] By setting the ranging module 50 in the heat dissipation cavity 113, the heat dissipation module 30 can also dissipate heat for the control board 40 at the same time, thereby improving the heat dissipation efficiency; and, since the surrounding wall 13 and the bottom wall of the heat dissipation cavity 113 are spaced apart, part of the ranging module 50 can also be located below the surrounding wall 13, thereby effectively utilizing the space and avoiding the laser 100 from being too large.

[0082] The present application also proposes a laser device, which includes a laser 100 as in any of the aforementioned embodiments. The laser device proposed in the present application may be a laser engraver, a laser cutter, a laser marker, or other equipment that uses laser ranging or positioning. Since the laser 100 proposed in the present application applies all the technical solutions of all the aforementioned embodiments, it at least has all the beneficial effects brought by all the aforementioned technical solutions, which will not be described in detail here.

[0083] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
