[0050] The core idea of ​​the present application is to provide a laser generating device with a simple structure and accurate indication of the laser action position. The following is a detailed description of a laser generating device with visible light provided in the embodiment of the present application in conjunction with the accompanying drawings of the present application.

[0051] Figure 1 FIG. 1 is a schematic diagram of the structure of a laser generating device with visible light provided in an embodiment of the present application. Figure 2 Shown is a schematic diagram of the optical path of a laser generating device with visible light provided in an embodiment of the present application; Figure 3 Shown Figure 1Cross-sectional view of the center optical axis adjustment structure.

[0052] Please combine Figure 1 , Figure 2 and Figure 3 The laser generating device with visible light of the present application comprises a glass laser tube 1, an indicator light generator 2, an optical mirror 3 and an optical axis adjustment structure 4; the light emitted by the glass laser tube 1 is invisible light; the light emitted by the indicator light generator 2 is visible light; the optical mirror 3 is located at the intersection of the outgoing light path of the glass laser tube 1 and the outgoing light path of the indicator light generator 2; the optical mirror 3 is used to transmit invisible light and reflect visible light; the optical axis adjustment structure 4 is used to adjust the position of the optical axis of the glass laser tube 1; the optical axis adjustment structure 4 includes The annular fixing frame 41 and a plurality of push rods 42 are included; the annular fixing frame 41 is arranged on the circumferential outer side of the glass laser tube 1; a plurality of mounting holes 411 are arranged on the annular fixing frame 41, and the plurality of mounting holes 411 are arranged along the circumference of the annular fixing frame 41, and the axes of the mounting holes 411 point to the central axis of the annular fixing frame 41; the push rod 42 is threadedly connected with the mounting hole 411, and one end of the push rod 42 extending out of the mounting hole 411 abuts against the glass laser tube 1; the position of the glass laser tube 1 is stabilized under the action of the plurality of push rods 42.

[0053] Please continue to refer to Figure 1 , Figure 2 and Figure 3 The present application is provided with a visible light laser generating device, in which the laser source for generating invisible light is a glass laser tube; the full name of the glass laser tube is glass-sealed CO2 laser, and because of its structure being encapsulated in a glass tube, it is commonly called a laser tube; the tube body of the glass laser tube is cylindrical and made of hard glass; because of its relatively low price and strong practicality, it has been recognized by domestic and foreign customers; it is currently widely used in cutting, engraving, marking, medical cosmetology and other fields.

[0054] The laser generating device with visible light provided in the present application uses a laser tube as a laser source, and thus has strong practicality and relatively low cost.

[0055] Please continue to refer to Figure 1 , Figure 2 and Figure 3In some embodiments of the present application, the indicator light generator 2 is arranged orthogonally to the glass laser tube 1, and the optical axes of the indicator light generator 2 and the glass laser tube 1 are orthogonal under ideal conditions; and an optical mirror 3 is arranged at the intersection of the outgoing light path of the glass laser tube 1 and the outgoing light path of the indicator light generator 2, and the outgoing light of the indicator light generator 2 is reflected by the optical mirror 3, and the outgoing light of the glass laser tube 1 is transmitted. In this way, under ideal conditions, after being processed by the optical mirror 3, the visible light emitted by the indicator light generator 2 and the invisible laser emitted by the glass laser tube 1 should be coaxial and in the same direction; but in fact, due to the installation tolerance of the glass laser tube 1 and the indicator light generator 2, there are about 90% of the laser generating devices, and the light emitting direction of the visible light cannot perfectly coincide with the light emitting direction of the glass laser tube 1. For some high-precision processing or treatment of key parts of the human body, the indicated direction of the indicator light cannot well represent the action position of the laser, and the actual effect of laser processing or laser medical treatment will be greatly reduced.

[0056] Based on this, the present application combines the appearance and structural characteristics of the glass laser tube 1 to change the fixing method of the glass laser tube 1; Figure 1 , Figure 2 and Figure 3 The optical axis adjustment structure 4 of the present application includes an annular fixing frame 41 and a plurality of push rods 42; the annular fixing frame 41 is arranged on the circumferential outer side of the glass laser tube 1; a plurality of mounting holes 411 are arranged on the annular fixing frame 41, and the plurality of mounting holes 411 are arranged along the circumference of the annular fixing frame 41, and the axis of the mounting hole 411 points to the central axis of the annular fixing frame 41; the push rod 42 is threadedly connected to the mounting hole 411, and one end of the push rod 42 extending out of the mounting hole 411 applies force toward the glass laser tube 1; the position of the glass laser tube 1 is stable under the action of the plurality of push rods 42, therefore, the optical axis adjustment structure 4 of the present application not only has an adjustment effect on the optical axis of the glass laser tube 1, but also has a function of fixing the glass laser tube 1.

[0057] Please combine Figure 1 , Figure 2 and Figure 3 Before using or installing the laser generating device with visible light, the indicator light generator 2 is usually allowed to emit an indicator light and mark the position of the light spot of the indicator light; then, using the position of the light spot of the indicator light as a reference, the position of the glass laser tube 1 is adjusted so that the action point of the glass laser tube 1 coincides with the position of the light spot of the indicator light; in this way, when the laser generating device is used, the action position of the laser can be determined by the direction of the indicator light.

[0058] Please continue to refer to Figures 1 to 3When adjusting the position of the glass laser tube 1, it can be adjusted through the top rods 42 at different positions on the annular fixing frame 41. The position of the glass laser tube 1 is changed by the extension and retraction of multiple top rods 42, so that the light emitting direction of the glass laser tube 1 is changed, and then it is in the same direction as the light emitting direction of the indication light.

[0059] In summary, the laser generating device with visible light of the present application adopts a glass laser tube 1 as a laser source, and in combination with the appearance and structural characteristics of the glass laser tube 1, changes are made in the fixing method of the glass laser tube 1, and the optical axis adjustment structure 4 is used to adjust the position of the glass laser tube 1, so that the light emitting direction of the glass laser tube 1 changes, and then it is coaxial and in the same direction as the light emitting direction of the indicator light. In this way, when the laser generating device is used for industrial processing or medical treatment, the action point of the indicator light represents the action position of the laser, which provides great convenience for the application of the laser; and the optical axis adjustment structure 4 of the present application is simple in composition, and has the functions of adjusting the optical axis of the glass laser tube 1 and fixing the glass laser tube 1; therefore, the laser generating device with visible light of the present application also has the characteristics of simple structure, low cost, and good optical path overlap effect.

[0060] It should be noted here that Figure 1 and Figure 2 Only one implementation method of the laser generating device with visible light of the present application is given, which is not intended to limit the present application. In fact, based on the concept of the present application, the laser generating device with visible light may also have other implementation methods. For example, the glass laser tube 1 may be located on the reflection side of the optical mirror 3, and the indicator light generator 2 may be located on the transmission side of the optical mirror 3. The optical mirror 3 reflects invisible light and transmits visible light.

[0061] Alternatively, in some embodiments of the present application, in order to meet other special indication requirements, it is required that the outgoing light of the glass laser tube 1 after passing through the optical mirror 3 and the outgoing light of the indication light generator 2 after passing through the optical mirror 3 have a certain angle; then the solution given in the present application is also applicable.

[0062] Or, if Figure 2As shown, in this example, the optical mirror 3 is located at the intersection of the outgoing light path of the glass laser tube 1 and the outgoing light path of the indicator light generator 2; then, after adjustment by the optical axis adjustment structure 4, the light-emitting direction of the visible light can coincide with the light-emitting direction of the glass laser tube 1; but in some other embodiments of the present application, if the light-emitting direction of the visible light is required to be parallel to but not coincident with the light-emitting direction of the glass laser tube 1, then the scheme given in the present application is also applicable, and it is only necessary to stagger the position where the indicator light generator 2 hits the optical mirror 3 and the position where the glass laser tube 1 hits the optical mirror 3; then, by adjusting the optical axis adjustment structure 4, the outgoing light of the glass laser tube 1 after passing through the optical mirror 3 is parallel to the outgoing light of the indicator light generator 2 after passing through the optical mirror 3.

[0063] In addition, it should be noted that Figure 3 As shown, in this example, the push rod 42 is a threaded rod, and the position of the glass laser tube is adjusted by rotating the push rod 42; however, the push rod 42 is not limited to the structure of a threaded rod, for example, it can be a hydraulic rod or an electric push rod.

[0064] Please refer to Figure 3 In some embodiments of the present application, the optical axis adjustment structure 4 further includes an elastic component 43 ; the elastic component 43 is disposed between the annular fixing frame 41 and the glass laser tube 1 , and the elastic component 43 and the top rod 42 are located on opposite sides of the glass laser tube 1 .

[0065] For more details, please refer to Figure 3 In some embodiments of the present application, an elastic component 43 is used in conjunction with a push rod 42. As described above, the position of the glass laser tube 1 can be adjusted by adjusting the difference in the force applied by the push rod 42 to the glass laser tube 1. In essence, the change in the position of the glass laser tube 1 is caused by the difference in the force applied to different positions on the periphery of the glass laser tube 1. In this case, the present application sets an elastic component 43, and the elastic component 43 and the push rod 42 are located on opposite sides of the glass laser tube 1. In this way, when the push rod 42 applies a force toward the glass laser tube 1, due to the small rigidity of the elastic component 43, even if the push rod 42 applies a small force toward the glass laser tube 1, the elastic component 43 will be relatively deformed. Therefore, the position of the glass laser tube 1 can be adjusted relatively easily.

[0066] In addition, as mentioned above, the glass laser tube 1 is encapsulated by a glass tube, so the glass laser tube 1 is relatively brittle and is prone to bursting when subjected to large forces. The present application adopts a combined structure of an elastic component 43 and a push rod 42, which can adjust the position of the glass laser tube 1 with a small force, thereby reducing the risk of bursting of the glass laser tube 1.

[0067] like Figure 3As shown, in some embodiments of the present application, the elastic component 43 may be a spring; however, the spring is not the only structure of the elastic component 43; for example, a rubber block or other elastic structure may be used; the present application does not impose any restrictions on this.

[0068] Furthermore, in order to ensure that the elastic component 43 is stably arranged on the opposite side of the top rod 42 so that the force of the top rod 42 can be accurately transmitted to the elastic part, a groove 412 for mounting the elastic component 43 is also provided on the side of the annular fixing frame 41 close to the glass laser tube 1, and the axis of the groove 412 is coaxial with the axis of the mounting hole 411; one end of the elastic component 43 is located in the groove 412, and the other end of the elastic component 43 is abutted against the glass laser tube 1.

[0069] Furthermore, in some embodiments of the present application, the laser generating device with visible light also includes a side panel 6, which is located on one side of the glass laser tube 1, and the annular fixing frame 41 is fixedly connected to the side panel 6; the groove 412 is arranged on the semicircle of the annular fixing frame 41 close to the side panel 6, and the mounting hole 411 is arranged on the semicircle of the annular fixing frame 41 away from the side panel 6.

[0070] For more details, please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of the present application, the laser generating device with visible light of the present application further includes a side plate 6; an important function of the side plate 6 is to enable the laser glass tube to be placed stably; the present application connects the annular fixing frame 41 to the side plate 6, so that the annular fixing frame 41 not only plays a role in adjusting the position of the glass laser tube 1, but also plays a role in fixing the glass laser tube 1 to the side plate 6, so that the glass laser tube 1 can be placed stably.

[0071] In addition, the present application sets the groove 412 on the semicircle of the annular fixing frame 41 close to the side plate 6, and sets the installation hole 411 on the semicircle of the annular fixing frame 41 away from the side plate 6, so that it is convenient to operate the top rod 42, and then facilitate the position adjustment of the glass laser tube 1.

[0072] Please continue to refer to Figure 3 In some embodiments of the present application, the optical axis adjustment structure 4 further includes a contact 44 , and the material of the contact 44 is engineering plastic; the contact 44 is arranged at the end of the top rod 42 , and the top rod 42 applies force to the glass laser tube 1 through the contact 44 .

[0073] Specifically, as mentioned above, the glass laser tube 1 is relatively brittle and is prone to bursting when subjected to greater force. In the present application, a contact 44 is provided at the end of a top rod 42, and the material of the contact 44 is engineering plastics. The engineering plastics have excellent comprehensive properties, greater rigidity, certain creep properties and good heat resistance, and may be polytetrafluoroethylene, polycarbonate, etc. Since the contact 44 has greater rigidity and certain creep properties, the contact 44 can not only better transmit the effect of the top rod 42 to the glass laser tube 1 and fix the glass laser tube 1, but also, to a certain extent, avoid damage to the laser tube. In addition, the contact 44 has a relatively high surface roughness and is not prone to slipping on the surface of the glass laser tube 1. Finally, the glass laser tube 1 generates heat during use, and the engineering plastics have good resistance, so the contact 44 can adapt to a higher temperature working environment and is not prone to deformation due to high temperature, which affects the direction of the emitted light of the glass laser tube 1. In summary, the present application adopts the contact 44 made of engineering plastic, so that the installation and adjustment requirements of the glass laser tube 1 can be better met.

[0074] Please continue to refer to Figure 1 and Figure 2 In some embodiments of the present application, the number of the optical axis adjustment structures 4 is two, and the two optical axis adjustment structures 4 are distributed along the length direction of the glass laser tube 1 .

[0075] For more details, please refer to Figure 1 and Figure 2 , assuming that the laser generating device with visible light shown in the figure is arranged in the horizontal direction, wherein the optical axis adjustment structure 4 close to the outlet end of the glass laser tube 1 is the first optical axis adjustment structure 4A, and the other optical axis adjustment structure 4 is the second optical axis adjustment structure 4B; then, when calibrating the laser generating device, if the light emitting direction of the glass laser tube 1 deviates greatly from the light emitting direction of the indicator light generator 2, the second optical axis adjustment structure 4B can be adjusted first, so that the position adjustment range of the glass laser tube 1 is large and can approach the ideal position more quickly; if the light emitting direction of the glass laser tube 1 deviates slightly from the light emitting direction of the indicator light generator 2, the first optical axis adjustment structure 4A can be adjusted, so that the position adjustment range of the glass laser tube 1 is small and can approach the ideal position better; thus, the present application sets two optical axis adjustment structures 4 in the length direction of the glass laser tube 1, and the two optical axis adjustment structures 4 can be used in combination to achieve a better and faster adjustment effect.

[0076] Please continue to refer to Figure 1 and Figure 2In some embodiments of the present application, the laser generating device further includes two fixing rings 5; the two fixing rings 5 ​​are located between the two optical axis adjustment structures 4 and are respectively arranged close to the adjacent optical axis adjustment structures 4; the fixing rings 5 ​​tightly embrace the glass laser tube 1 to prevent the glass laser tube 1 from axial displacement.

[0077] For more details, please refer to Figure 1 and Figure 2 , assuming that the laser generating device with visible light shown in the figure is arranged in the horizontal direction, wherein the fixing ring 5 close to the outlet end of the glass laser tube 1 is the first fixing ring 5A, and the other fixing ring 5 is the second fixing ring 5B; as mentioned above, in order to prevent the glass laser tube 1 from bursting, the force applied by the optical axis adjustment structure 4 to the glass laser tube 1 is not very large, therefore, in the case of vibration, if there is no relevant fixing measure in the axial direction of the glass laser tube 1, the glass laser tube 1 may be axially displaced, and the glass laser tube 1 is at risk of being damaged; Figure 1 and Figure 2 As shown, the first fixing ring 5A is close to the first optical axis adjustment structure 4A, and the second fixing ring 5B is close to the second optical axis adjustment structure 4B; thus, when the glass laser tube 1 is about to move toward the first direction D1, the second optical axis adjustment structure 4B will block the second fixing ring 5B. Since the second fixing ring 5B hugs the glass laser tube 1, the second optical axis adjustment structure 4B prevents the glass laser tube 1 from moving toward the first direction D1 by blocking the second fixing ring 5B; similarly, when the glass laser tube 1 is about to move toward the second direction D2, the first optical axis adjustment structure 4A will block the first fixing ring 5A. Since the first fixing ring 5A hugs the glass laser tube 1, the first optical axis adjustment structure 4A prevents the glass laser tube 1 from moving toward the second direction D2 by blocking the first fixing ring 5A.

[0078] Based on the above, the present application prevents the axial displacement of the glass laser tube 1 by the cooperation between the fixing ring 5 and the optical axis adjustment structure 4, thereby increasing the structural stability and reliability of the laser generating device.

[0079] Figure 4 The figure shows the combined structure diagram of the fixing ring 5 and the glass laser tube 1 provided in the embodiment of the present application. Figure 4 In some embodiments of the present application, the fixing ring 5 includes an outer ring 51 and an inner ring 52; the inner ring 52 is an elastic ring, and the inner ring 52 is sleeved on the outer circumference of the glass laser tube 1; the outer ring 51 is a rigid ring, including a first part and a second part; the first part and the second part embrace the inner ring 52, and are fastened by fasteners 53 to make the inner ring 52 close to the glass laser tube 1.

[0080] Please combine Figure 1 , Figure 2 and Figure 4 As mentioned above, in order to prevent the glass laser tube 1 from axial position deviation, the fixing ring 5 is provided on the outer periphery of the glass laser tube 1. The fixing ring 5 must hold the glass laser tube 1 tightly to play a corresponding role. Based on this, there must be a large friction between the fixing ring 5 and the glass laser tube 1, so that the two may not slide relative to each other; the fixing ring 5 of the present application adopts a combination of an elastic ring and a rigid ring, so that, on the one hand, there can be a strong friction between the fixing ring 5 and the glass laser tube 1; on the other hand, it also helps to prevent the glass tube from bursting.

[0081] Furthermore, in some embodiments of the present application, an axial fixing member is provided between the fixing ring 5 and the annular fixing frame 41 of the adjacent optical axis adjustment structure 4 along the axial direction of the glass laser tube 1 ; a radial fixing member is provided between the fixing ring 5 and the side plate 6 along the axial direction of the glass laser tube 1 .

[0082] For more details, please refer to Figure 2 and Figure 3 As mentioned above, the annular fixing frame 41 of the optical axis adjustment structure 4 in the present application is fixedly connected to the side plate 6. On this basis, the present application further stabilizes the axial position of the fixing ring 5 on the glass laser tube 1 by setting an axial fixing member between the fixing ring 5 and the annular fixing frame 41, so that the fixing ring 5 remains stable even under harsh conditions such as vibration, thereby better preventing the axial movement of the glass laser tube 1.

[0083] It should be noted that the axial fixing member in the present application can be a hot melt adhesive arranged between the fixing ring 5 and the adjacent optical axis adjustment structure 4, or it can be a plug-in limiting structure arranged between the fixing ring 5 and the adjacent optical axis adjustment structure 4, and the present application does not impose any limitation on this.

[0084] See also Figure 3 In some embodiments of the present application, the position of the glass laser tube 1 is adjusted by using an elastic component 43 in combination with a push rod 42. Since the elastic component 43 has a certain elasticity, the glass laser tube 1 has a certain possibility of radial deviation. In order to prevent the glass laser tube 1 from radial deviation, the present application provides a radial fixing member between the fixing ring 5 and the side plate 6. After the radial fixing member is used, the radial position of the fixing ring 5 does not change, and the radial position of the glass laser tube 1 does not change, and the laser generating device can continue to maintain good accuracy. The radial fixing member of the present application can be a filling glue or a plastic limit block, and the present application does not impose any restrictions.

[0085] Please continue to refer to Figure 1In some embodiments of the present application, the optical axis of the glass laser tube 1 is orthogonal to the optical axis of the indicator light generator 2; the angle between the optical mirror 3 and the optical axis of the glass laser tube 1 is 45°; in this way, it is convenient to make the outgoing light of the glass laser tube 1 after passing through the optical mirror 3 and the outgoing light of the indicator light generator 2 after passing through the optical mirror 3 coaxial and in the same direction, which is convenient for installation and adjustment.

[0086] Please continue to refer to Figure 3 In some embodiments of the present application, the top rod 42 is a screw rod, and the optical axis adjustment structure 4 also includes a locking nut 45, which is used to prevent the top rod 42 from loosening, thereby helping to maintain the accuracy of the laser generating device.

[0087] Specifically, when the locking nut 45 is locked on the top rod 42, it may affect the light emitting direction of the glass laser tube 1. In this case, it is necessary to turn on the glass laser tube 1 and the indicator light generator 2 again to check whether the light emitting direction of the glass laser tube 1 has changed. If it has changed, it is necessary to adjust the light emitting direction of the glass laser tube 1 again, and then tighten the locking nut 45. This process can be repeated until the light emitting direction of the glass laser tube 1 still meets the requirements after the locking nut 45 is locked.

[0088] Based on the special structure of the laser generating device of the present application, the present application also provides a method for installing and debugging the laser generating device, which comprises the following steps:

[0089] 1) Install the indicator light generator 2;

[0090] 2) Installing the glass laser tube 1. When installing the glass laser tube 1, the installation position of the glass laser tube 1 is adjusted by the optical axis adjustment structure 4, so that the output light of the glass laser tube 1 and the output light of the indicator light generator 2 are coaxial and in the same direction after passing through the optical mirror 3;

[0091] 3) Apply glue between the optical axis adjustment structure 4 and the adjacent fixing ring 5, and apply glue between the fixing ring 5 and the side plate to fix the adjusted state of the glass laser tube (1). The laser generating device with visible light of the present application can adjust the emitted light of the glass laser tube 1 during the installation process of the glass laser tube 1 so that it coincides with the indication light, and then fix the adjusted state by applying glue. In this way, in subsequent use, it is generally not necessary to adjust the emitted light direction of the glass laser tube 1 again to maintain good accuracy; in addition, the optical axis adjustment structure 4 of the laser generating device with visible light of the present application is both the installation structure of the glass laser tube 1 and the adjustment structure of the glass laser tube 1. Therefore, the laser generating device with visible light of the present application also has the characteristics of simple structure.

[0092] Furthermore, when adjusting the installation position of the glass laser tube 1 through the optical axis adjustment structure 4, the following steps may be adopted:

[0093] 2.1) Laser low beam adjustment: Set a first target near the light outlet of the laser generating device with visible light, turn on the glass laser tube 1 and the indicator light generator 2, and adjust the first optical axis adjustment structure 4A so that the outgoing light of the glass laser tube 1 and the outgoing light of the indicator light generator 2 coincide with the action position of the first target;

[0094] 2.2) Laser high beam adjustment: Set a second target at a position far away from the light outlet of the laser generating device with visible light, turn on the glass laser tube 1 and the indicator light generator 2, and make the output light of the glass laser tube 1 and the output light of the indicator light generator 2 coincide with the action position on the second target by alternately adjusting the second optical axis adjustment structure 4B and / or the first optical axis adjustment structure 4A.

[0095] In this way, the laser generating device with visible light of the present application not only adjusts the low beam but also adjusts the high beam during the installation process of the glass laser tube 1. Therefore, whether in the low beam area or the high beam area of ​​the laser generating device, the indicator light has a good indicating effect on the invisible laser.

[0096] In addition, as an embodiment of the present application, when performing laser adjustment, the distance between the targets of the high beam and the low beam is 50CM, and this distance can also be adjusted according to actual applications.

[0097] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation modes of the present application.
