A mechanical self-rebound device for laser collimation

Abstract

This utility model relates to the field of laser technology, specifically to a mechanical self-rebound device for laser collimation. It includes a support back plate, a reflector frame on the outer side of the support back plate, and adjustment array mounting positions distributed along the direction of the laser diode array on the reflector frame. An angle adjustment block is located on the front of each adjustment array mounting position, and two sets of self-rebound components are located inside each adjustment array mounting position. A reflector is fixedly connected to the front of each angle adjustment block. Compared with existing self-rebound devices, when the moving rod is subjected to external force and displacement occurs, it will compress the angle adjustment block, causing the angle of the reflector to change. At this time, the first compression spring is compressed, storing elastic potential energy. When the external force disappears, the first compression spring releases the elastic potential energy, driving the moving sleeve and moving rod to reset, thereby achieving automatic self-rebound of the reflector. Through the overall design, it can effectively drive the automatic self-rebound of the reflector.

Description

Technical Field

[0001] This utility model relates to the field of laser technology, specifically to a mechanical self-rebound device for laser collimation. Background Technology

[0002] Laser light sources offer significant advantages over traditional lamp-based light sources in the projection display industry, and are considered a revolutionary light source for the sector. Their ultra-wide color gamut and ultra-high color saturation cater to consumers' pursuit of ultimate image quality, while their extended lifespan saves cinema operators the costs of frequent lamp replacements and labor costs associated with equipment maintenance. Therefore, laser projection has received increasing attention in the display industry, especially in cinema projection, in recent years.

[0003] A search revealed that CN210323745U discloses a mechanical self-rebound device for laser collimation, comprising a support back plate, a reflector frame mounted on the support back plate, and adjustment array mounting stations distributed along the direction of the number of laser diode arrays on the reflector frame. Each adjustment array mounting station is connected to an angle adjustment block via a support column, and two adjustment screws for fine-tuning the angle adjustment block are installed in parallel at each adjustment array mounting station. A reflector is mounted on the front of the angle adjustment block, and each reflector is set at 45° to the forward direction of the laser beam emitted by the corresponding laser diode. The structure of the "mechanical self-rebound laser collimation device" allows for multi-dimensional adjustment compared to the original adjustment structure, and the time required is shorter than that of traditional techniques. However, its drawback is that the device relies solely on the elastic deformation of the angle adjustment block during rebound. Over time, wear on the angle adjustment block affects the resetting effect. Therefore, improving the existing self-rebound device and designing a new type of mechanical self-rebound device for laser collimation to address these technical shortcomings and improve the overall practicality of the self-rebound device is of paramount importance. Utility Model Content

[0004] The purpose of this invention is to provide a mechanical self-returning device for laser collimation. When the moving rod is displaced by an external force, it will squeeze the angle adjustment block, causing the angle of the reflector to change. At this time, the first compression spring is compressed and stores elastic potential energy. When the external force disappears, the first compression spring releases the elastic potential energy, driving the moving sleeve and the moving rod to reset, thereby realizing the automatic rebound and reset of the reflector. Through the overall design, it can effectively drive the automatic rebound and reset of the reflector, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mechanical self-rebound device for laser collimation includes a support back plate, a mirror frame on the outer side of the support back plate, an adjustment array mounting station distributed along the direction of the number of laser diode arrays on the mirror frame, an angle adjustment block on the front of the adjustment array mounting station, two sets of self-rebound components inside the adjustment array mounting station, and a mirror fixedly connected to the front of the angle adjustment block.

[0007] The self-rebound assembly is used for resetting the radiation mirror. The self-rebound assembly consists of a sleeve, a moving rod, a moving sleeve, a rotating block, a connecting column, and multiple sets of guide bars. The sleeve is fixedly connected to the inside of the adjustment array installation position. The moving rod is slidably connected to the front end inside the sleeve. The moving sleeve is fixedly connected to the rear end of the moving rod. The rotating block is rotatably connected to the rear end inside the sleeve. The connecting column is fixedly connected to the front end of the rotating block. Multiple sets of guide bars are fixedly connected to the four sides of the outside of the connecting column.

[0008] As a preferred embodiment of this utility model, the rear end of the movable sleeve is provided with multiple sets of guide grooves, the guide strip is slidably connected to the guide grooves, and the guide grooves are designed with an inclined surface structure.

[0009] As a preferred embodiment of this utility model, the front end of the movable rod is fixedly connected to the angle adjustment block, and a first compression spring is sleeved on the outside of the movable rod and inside the sleeve, with the two ends of the first compression spring being fixedly connected to the sleeve and the movable sleeve respectively.

[0010] As a preferred embodiment of this utility model, the rotating block extends to the back of the adjustment array mounting station and is fixedly connected to a rotating rod, and the rotating rod is rotatably connected to the adjustment array mounting station.

[0011] As a preferred embodiment of this utility model, the rear end of the rotating rod is slidably connected to two sets of limiting rods, and the back of the adjustment array installation station is provided with two sets of limiting grooves. The adjustment array installation station is connected to the limiting rods through the limiting grooves.

[0012] As a preferred embodiment of this utility model, a movable ring is fixedly connected to the outside of the limiting rod and inside the rotating rod, and a second compression spring is fixedly connected to the outside of the movable ring and outside the limiting rod. The second compression spring is fixedly connected to both the movable ring and the rotating rod, and the two sets of limiting rods are connected by a connecting rod.

[0013] As a preferred embodiment of this utility model, a support column is fixedly connected to the back of the angle adjustment block, and the end of the support column away from the angle adjustment block is fixedly connected to the adjustment array installation position.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the design of the self-rebound component allows the moving rod to be displaced by external force, which in turn compresses the angle adjustment block, causing the angle of the reflector to change. At this time, the first compression spring is compressed and stores elastic potential energy. When the external force disappears, the first compression spring releases the elastic potential energy, driving the moving sleeve and the moving rod to reset, thereby realizing the automatic rebound and reset of the reflector. Through the overall design, the automatic rebound and reset of the reflector can be effectively achieved. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figures 1-6 This utility model provides a technical solution:

[0026] A mechanical self-rebound device for laser collimation includes a support back plate 1, a reflector frame 2 on the outer side of the support back plate 1, an adjustment array mounting station 3 distributed along the direction of the number of laser diode arrays on the reflector frame 2, an angle adjustment block 4 on the front of the adjustment array mounting station 3, two sets of self-rebound components 5 inside the adjustment array mounting station 3, and a reflector 6 fixedly connected to the front of the angle adjustment block 4.

[0027] The self-rebound assembly 5 is used for resetting the radiation mirror 6. The self-rebound assembly 5 consists of a sleeve 7, a moving rod 8, a moving sleeve 9, a rotating block 10, a connecting post 11, and multiple sets of guide bars 12. The sleeve 7 is fixedly connected to the inside of the adjustment array installation station 3. The moving rod 8 is slidably connected to the front end inside the sleeve 7. The moving sleeve 9 is fixedly connected to the rear end of the moving rod 8. The rotating block 10 is rotatably connected to the rear end inside the sleeve 7. The connecting post 11 is fixedly connected to the front end of the rotating block 10. Multiple sets of guide bars 12 are all fixedly connected to the four sides of the outside of the connecting post 11.

[0028] Furthermore, the rear end of the movable sleeve 9 is provided with multiple sets of guide grooves 13. The guide strip 12 and the guide groove 13 are slidably connected. The guide groove 13 is designed with an inclined structure. When the rotating block 10 rotates, it drives the connecting column 11 to rotate, so that the multiple sets of guide strips 12 move in an arc shape with the connecting column 11 as the center. The guide groove 13 drives the movable sleeve 9 to move, so that the movable rod 8 moves.

[0029] The front end of the moving rod 8 is fixedly connected to the angle adjustment block 4. A first compression spring 14 is sleeved on the outside of the moving rod 8 and inside the sleeve 7. The two ends of the first compression spring 14 are fixedly connected to the sleeve 7 and the moving sleeve 9, respectively. When the moving rod 8 moves, it can squeeze the angle adjustment block 4. The angle adjustment block 4 deforms due to the force provided by the moving rod 8, which causes the beam angle to change. Multiple angle adjustment frames are distributed according to the laser diode array and fixed on the reflector frame 2, thus completing the high-power laser coupling. When the reflector 6 needs to be reset, the first compression spring 14 works with the sleeve 7 to drive the moving sleeve 9 to reset, thereby resetting the moving rod 8 and driving the angle adjustment block 4 to reset.

[0030] Secondly, a rotating rod 15 is fixedly connected to the back of the rotating block 10 extending to the adjustment array installation station 3. The rotating rod 15 is rotatably connected to the adjustment array installation station 3, and rotating the rotating rod 15 can drive the rotating block 10 to rotate.

[0031] Furthermore, two sets of limiting rods 16 are slidably connected to the rear end of the rotating rod 15. Two sets of limiting grooves are provided on the back of the adjustment array installation station 3. The adjustment array installation station 3 is connected to the limiting rods 16 through the limiting grooves, so that the limiting rods 16 can be displaced from the inside of the limiting grooves, allowing the rotating rod 15 to rotate.

[0032] Furthermore, a moving ring 17 is fixedly connected to the outside of the limiting rod 16 and inside the rotating rod 15. A second compression spring 18 is fixedly connected to the outside of the moving ring 17 and outside the limiting rod 16. The second compression spring 18 is fixedly connected to both the moving ring 17 and the rotating rod 15. The two sets of limiting rods 16 are connected by a connecting rod 19. Pulling the connecting rod 19 causes the two sets of limiting rods 16 to move, thus displacing them from the inside of the limiting groove and releasing the lock on the rotating rod 15. When it is necessary to lock the position of the moving rod 8, the connecting rod 19 is released, and the second compression spring 18 causes the moving ring 17 to move, thus displacing the limiting rod 16. The limiting rod 16 is moved to the inside of the limiting groove and connected to the limiting position 3 of the adjustment array installation station, thereby limiting the rotating rod 15 and locking the moving rod 8.

[0033] Furthermore, a support column 20 is fixedly connected to the back of the angle adjustment block 4. The end of the support column 20 away from the angle adjustment block 4 is fixedly connected to the adjustment array installation station 3. When the angle adjustment block 4 is squeezed, it can be guided by the support column 20.

[0034] In this embodiment, the specific implementation scenario is as follows: In actual use, pulling the connecting rod 19 causes the two sets of limiting rods 16 to move, thereby displacing the inside of the limiting groove, releasing the lock on the rotating rod 15. Rotating the rotating rod 15 causes the rotating block 10 to rotate. When the rotating block 10 rotates, it causes the connecting column 11 to rotate, causing multiple sets of guide bars 12 to move in an arc shape around the connecting column 11. Through the guide groove 13, it causes the moving sleeve 9 to move, causing the moving rod 8 to move. When the moving rod 8 moves, it can squeeze the angle adjusting block 4. The angle adjusting block 4 deforms due to the force provided by the moving rod 8, causing the beam angle to change. Multiple angle adjusting frames are distributed according to the laser diode array and fixed to the reflector. On frame 2, high-power laser coupling is completed. The connecting rod 19 is released, and the moving ring 17 is displaced by the second compression spring 18, causing the limiting rod 16 to move. The limiting rod 16 is moved into the limiting groove and connected to the limiting connection of the adjustment array installation station 3, which can limit the rotating rod 15 and lock the moving rod 8. When the reflector 6 needs to be reset, the rotating rod 15 is rotated, causing the guide bar 12 to move to the bottom of the guide groove 13. The first compression spring 14, in conjunction with the sleeve 7, drives the moving sleeve 9 to reset, thereby resetting the moving rod 8 and driving the angle adjustment block 4 to reset. Compared with the existing self-rebound device, this utility model can improve the overall practicality of the self-rebound device through design.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
