Description

Technical Field

[0001] This utility model relates to the field of lasers, and in particular to a focusable uniform line laser. Background Technology

[0002] A uniform line laser, also known as a line laser, is a type of semiconductor laser used to form a uniform, straight laser line. It is widely used in collimation, machinery, construction, and manufacturing industries. Because lasers require focusing under different conditions to suit various applications, a focusing device is needed for this purpose.

[0003] Changing the focal length will affect the focal point and the degree of focusing of the laser beam. When the laser sensor needs to measure objects at a distance, the lens needs to be adjusted to better focus the beam. Conversely, when the laser sensor needs to measure objects at a closer distance, the lens needs to be adjusted to better defocus the beam.

[0004] Existing small laser focusing devices consist of a mounting sleeve, a focusing sleeve, and an internal focusing lens. Focusing is achieved by changing the distance between the focusing lens and the laser's emission port. Most current laser focusing mechanisms are manual, which is inconvenient when measuring objects with significant differences in distance, requiring long-distance movement of the focusing lens. Utility Model Content

[0005] To facilitate laser focusing, this application provides a focusable uniform line laser.

[0006] This application provides a tunable focus uniform line laser using the following technical solution:

[0007] A tunable-focus uniform line laser includes a laser housing and a focusing assembly. The focusing assembly is used for focusing the laser. The focusing assembly includes a movable plate, multiple focusing lenses, a first driving assembly, and a second driving assembly. The movable plate is slidably connected inside the laser housing. The movable plate has a through hole. The multiple focusing lenses are rotatably connected to the movable plate around its central axis. The distances between the multiple focusing lenses and the movable plate are different. The through hole is coaxial with any of the focusing lenses. The first driving assembly drives the multiple focusing lenses to rotate simultaneously, and the second driving assembly drives the movable plate to slide.

[0008] By adopting the above technical solution, multiple focusing lenses are driven to rotate by the first driving component, so that the focusing lens that needs to be distanced is coaxial with the through hole. Then, the moving plate is driven to slide by the second driving component to make fine adjustment of the position of the focusing lens, which facilitates manual focusing of the laser.

[0009] Preferably, the first driving component includes a turntable and a plurality of sleeves. The turntable is coaxial with and rotatably connected to the movable plate. The plurality of focusing lenses correspond to the plurality of sleeves respectively. The plurality of focusing lenses are fixedly connected to the corresponding sleeves respectively. The plurality of sleeves are respectively inserted through and fixedly connected to the turntable. The lengths of the plurality of sleeves are different.

[0010] By adopting the above technical solution, the turntable is rotated, thereby causing multiple sleeves on the turntable and their corresponding focusing lenses to rotate, so that the focusing lenses at the corresponding distances are coaxial with the through holes, which facilitates the focusing of the laser.

[0011] Preferably, the first drive assembly further includes a first motor, which is fixedly connected to the movable plate, and one end of the output shaft of the first motor is coaxially and fixedly connected to the turntable.

[0012] By adopting the above technical solution, the rotation of the turntable driven by the first motor is reduced, which reduces the possibility that the focusing lens cannot be coaxial with the through hole, thus facilitating the focusing of the laser.

[0013] Preferably, the second driving assembly includes a screw and a driving source. The screw is rotatably connected inside the laser housing along the sliding direction of the moving plate. One end of the screw passes through and is threadedly connected to the sliding plate. The driving source is used to drive the rotation of the screw.

[0014] By adopting the above technical solution, the drive source drives the screw to rotate, and through the threaded connection between the screw and the sliding plate, the sliding plate slides along the axis of the screw, so as to further focus the focusing lens and facilitate the focusing of the laser.

[0015] Preferably, the driving source includes a second motor, which is slidably connected inside the laser housing. One end of the output shaft of the second motor is coaxially and fixedly connected to a second gear, and a first gear is coaxially and fixedly connected to the screw. When the second motor slides to its limit position towards the screw, the first gear and the second gear mesh.

[0016] By adopting the above technical solution, when the first gear meshes with the second gear, the second motor drives the second gear to rotate. Through the meshing connection between the second gear and the first gear, the first gear and the screw fixedly connected to it rotate, which facilitates the focusing of the laser.

[0017] Preferably, the drive source further includes a paddle and a third gear. The paddle is slidably connected to the laser housing along the sliding direction of the second motor, and the third gear is rotatably connected to the paddle. When the paddle slides to its limit position toward the second motor, the first gear and the third gear mesh.

[0018] By adopting the above technical solution, force is applied to the lever to make it slide toward the second motor side. When the first gear and the third gear mesh, force is applied to the lever to make it rotate, thereby causing the third gear to rotate. Through the meshing connection between the third gear and the first gear, the first gear and the screw fixedly connected to it rotate, which facilitates the focusing of the laser.

[0019] Preferably, the paddle is provided with a connecting rod, and the end of the connecting rod away from the paddle is fixedly connected to the second motor.

[0020] By adopting the above technical solution, when the paddle slides towards the second motor, the second motor slides away from the screw, reducing the possibility that the paddle and the second motor will simultaneously drive the screw to rotate.

[0021] The main technical effects of this utility model are reflected in the following aspects:

[0022] 1. This utility model sets up multiple focusing lenses and a moving plate. The first driving component drives the multiple focusing lenses to rotate so that the focusing lens that needs to be distanced is coaxial with the through hole. Then, the second driving component drives the moving plate to slide so as to make fine adjustment of the position of the focusing lens, which is convenient for manual focusing of the laser.

[0023] 2. This utility model, by setting a first driving component, rotates the turntable, thereby causing multiple sleeves on the turntable and their corresponding focusing lenses to rotate, so that the focusing lenses at the corresponding distances are coaxial with the through holes, which facilitates the focusing of the laser;

[0024] 3. By setting a second driving component, the driving source drives the screw to rotate. Through the threaded connection between the screw and the sliding plate, the sliding plate slides along the axis of the screw, which allows for further focusing of the focusing lens and facilitates the focusing of the laser.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0031] This application discloses a focusable uniform line laser.

[0032] Reference Figures 1-4 This embodiment of a focusable uniform line laser includes a laser housing 1 and a focusing assembly 2. The focusing assembly 2 is used for focusing the laser. The focusing assembly 2 includes a movable plate 21, multiple focusing lenses 22, a first driving assembly 23, and a second driving assembly 24. The movable plate 21 is slidably connected inside the laser housing 1. A through hole 211 is provided on the movable plate 21. The multiple focusing lenses 22 are rotatably connected to the movable plate 21 around the central axis of the movable plate 21. The distances between the multiple focusing lenses 22 and the movable plate 21 are different. The through hole 211 is coaxial with any of the focusing lenses 22. The first driving assembly 23 is used to drive the multiple focusing lenses 22 to rotate simultaneously. The second driving assembly 24 is used to drive the movable plate 21 to slide.

[0033] Reference Figures 1-4 The first drive assembly 23 drives multiple focusing lenses 22 to rotate, so that the focusing lens 22 that needs to be distanced is coaxial with the through hole 211. Then, the second drive assembly 24 drives the moving plate to slide, so as to make fine adjustment of the position of the focusing lens, which is convenient for manual focusing of the laser.

[0034] Reference Figures 2-4The first driving assembly 23 includes a turntable 231 and multiple sleeves 232. The turntable 231 is coaxial with and rotatably connected to the movable plate 21. Multiple focusing lenses 22 correspond to multiple sleeves 232, and each focusing lens 22 is fixedly connected to its corresponding sleeve 232. The multiple sleeves 232 are respectively inserted through and fixedly connected to the turntable 231, and the lengths of the multiple sleeves 232 are different. Rotating the turntable 231 causes the multiple sleeves 232 and their corresponding focusing lenses on the turntable 231 to rotate, thereby making the focusing lenses at the corresponding distances coaxial with the through-hole 211, facilitating the focusing of the laser. The first driving assembly 23 also includes a first motor 233, which is fixedly connected to the movable plate 21. One end of the output shaft of the first motor 233 is coaxial with and fixedly connected to the turntable 231. By driving the turntable 231 to rotate through the first motor 233, the possibility of the focusing lenses not being coaxial with the through-hole 211 is reduced, facilitating the focusing of the laser.

[0035] Reference Figures 2-4 The second drive assembly 24 includes a screw 241 and a drive source 242. The screw 241 is rotatably connected to the laser housing 1 along the sliding direction of the moving plate 21. One end of the screw 241 passes through and is threadedly connected to the sliding plate. The drive source 242 is used to drive the rotation of the screw 241. The drive source 242 drives the rotation of the screw 241, and through the threaded connection between the screw 241 and the sliding plate, the sliding plate slides along the axial direction of the screw 241, thereby further focusing the focusing lens and facilitating the focusing of the laser.

[0036] Reference Figures 2-4 The drive source 242 includes a second motor 2426, which is slidably connected inside the laser housing 1. One end of the output shaft of the second motor 2426 is coaxially and fixedly connected to a second gear 2421. A first gear 2422 is coaxially and fixedly connected to a screw 241. When the second motor 2426 slides to its limit position towards the screw 241, the first gear 2422 and the second gear 2421 mesh. When the first gear 2422 meshes with the second gear 2421, the second motor 2426 drives the second gear 2421 to rotate. Through the meshing connection between the second gear 2421 and the first gear 2422, the first gear 2422 and the screw 241 fixedly connected to it rotate, facilitating laser focusing.

[0037] Reference Figures 1-4The drive source 242 also includes a paddle 2423 and a third gear 2424. The paddle 2423 is slidably connected to the laser housing 1 along the sliding direction of the second motor 2426. The third gear 2424 is rotatably connected to the paddle 2423. When the paddle 2423 slides to its limit position towards the second motor 2426, the first gear 2422 meshes with the third gear 2424. Applying force to the paddle 2423 causes it to slide towards the second motor 2426. When the first gear 2422 meshes with the third gear 2424, applying force to the paddle 2423 causes it to rotate, thereby rotating the third gear 2424. Through the meshing connection between the third gear 2424 and the first gear 2422, the first gear 2422 and the screw 241 fixedly connected to it rotate, facilitating the focusing of the laser. A connecting rod 2425 is rotatably connected to the paddle 2423 along the sliding direction of the paddle 2423. The end of the connecting rod 2425 away from the paddle 2423 is fixedly connected to the second motor 2426. When the paddle 2423 slides toward the second motor 2426, it causes the second motor 2426 to slide away from the screw 241, reducing the possibility that the paddle 2423 and the second motor 2426 will simultaneously drive the screw 241 to rotate.

[0038] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
