Abstract
Description
Technical Field
[0001] This application belongs to the field of laser emitting device manufacturing technology, specifically a laser bidirectional simultaneous emitting device. Background Technology
[0002] A single laser emitter can only emit laser light in one direction. Therefore, if two laser beams are needed, two laser emitters must be purchased, increasing costs. Especially when the laser beam needs to travel a long distance, its brightness decreases as it travels. Therefore, when a long laser beam is required, several laser emitters need to be arranged in a row so that the laser emitted by one emitter covers a specific distance. This method, with its increased number of emitters, further increases costs. Utility Model Content

[0019] join Figure 1-4A bidirectional simultaneous laser emission device includes an opaque outer shell 1. A laser emitter 2 is disposed through the top wall of the outer shell 1. The emission direction of the laser emitter 2 faces the inner bottom wall of the outer shell 1. A beam splitter and a beam emitter are respectively disposed inside the outer shell 1 by a first linear driver and a second linear driver. The direction in which the first linear driver drives the beam splitter to move is parallel to the direction in which the second linear driver drives the beam emitter to move, and is also parallel to the direction of the light emitted by the laser emitter 2. A first plane mirror 3 and a second plane mirror 4 are respectively disposed below the beam splitter and the beam emitter inside the outer shell 1. The light inlet of the beam splitter is located directly below the laser emitter 2. The first light emitting part of the beam splitter faces outward from the outer shell 1, and the second light emitting part of the beam splitter faces the first plane mirror 3. The light emitted from the second light emitting part enters the first plane mirror 3, is reflected, enters the second plane mirror 2, and is then emitted from inside the outer shell 1 to outside the outer shell 1 through the beam emitter. The angle between the light emitted by the beam emitter and the light emitted by the first light emitting part is 180°.
[0020] In this embodiment, the laser beam m emitted by laser emitter 2 enters the beam splitter and is split into laser beam a and laser beam b. Laser beam a is emitted directly from the first light-emitting section to the outside of the housing 1, while laser beam b is reflected by the first plane mirror 3 and the second plane mirror 4 and then emitted from the second light-emitting section to the outside of the housing 1. This forms two laser beams, laser beam a and laser beam b, from the laser emitted by one laser emitter 2. In other words, if two laser beams are needed, this invention can obtain two laser beams using only one laser emitter 2, saving costs compared to conventional technologies by eliminating the need for one laser emitter 2. Furthermore, when the range of the laser emitted by one laser emitter 2 is insufficient, assuming a range of 16 meters is required, the beam splitter and the light-emitting section can be adjusted using the first and second linear drivers respectively, ensuring that the emitted laser beam a and laser beam b are collinear. This invention is then placed at the midpoint of the 16-meter range, so that laser beam a illuminates half of the entire 16-meter range, while laser beam b illuminates the other half, thus solving the problem and eliminating the need for two laser emitters 2. If this method is applied more broadly, and if a 32-meter irradiation range is required, each laser emitter 2 has a range of only 8 meters, then using traditional technology would require 4 laser emitters 2, while using this application would only require 2, which means that the number of laser emitters 2 used is reduced by half, thus saving costs.
[0021] In a preferred embodiment, the first linear actuator is a first cylinder 5, with the free end of the piston rod of the first cylinder 5 fixedly connected to the beam splitter. The first cylinder 5 is parallel to the light emitted by the laser emitter 2. Thus, the position of laser a is adjusted by controlling the up-and-down movement of the beam splitter via the first cylinder 5.
[0022] In a preferred embodiment, the second linear actuator includes a second cylinder 6, the free end of which is fixedly connected to the light emitter. The piston rod of the second cylinder 6 is parallel to the light emitted by the laser emitter 2. Thus, the position of the laser b is adjusted by controlling the up-and-down movement of the beam-splitting emitter via the first cylinder 5.
[0023] In a preferred embodiment, the beam-splitting emitter includes a first frame 7 and a planar lens 8. The top wall of the first frame 7 has a first light-inlet hole 9, the bottom wall of the first frame 7 has a first light-outlet hole 10, and the side wall of the first frame 7 has a second light-outlet hole 11. The first light-inlet hole 9 and the first light-outlet hole 10 are coaxial, with the first light-outlet hole 10 serving as the second light-outlet portion and the second light-outlet hole 11 serving as the first light-outlet portion. The axis of the first light-inlet hole 9 is collinear with the light emitted by the laser emitter 2, and the first light-inlet hole 9 is located directly below the laser emitter 2. The axis of the second light-outlet hole 11 is perpendicular to the light emitted by the laser emitter 2. The planar lens 8 is fixedly installed inside the first frame 7. The angle between the axis of the planar lens 8 and the axis of the first light-emitting hole 10 is 45°, and the angle between the axis of the planar lens 8 and the axis of the second light-emitting hole 11 is 45°. The first light-emitting hole 10 and the second light-emitting hole 11 are located on opposite sides of the planar lens 8. The axis of the second light-emitting hole 11 and the axis of the first light-emitting hole 10 are in the same plane A, which is perpendicular to the planar lens 8. The free end of the piston rod of the first cylinder 5 is fixedly connected to the top of the first frame 7 away from the first light-inlet hole 9. One end of the second light-emitting hole 11 extends outside the outer shell 1. With this configuration, a portion of the laser m entering the planar lens 8 is reflected by the planar lens 8 to form laser a, and another portion is reflected by the planar lens 8 to form laser b. Laser b then passes through the first planar reflector 3, the second planar reflector 4, and the third planar reflector 15 before being output outside the outer shell 1, ensuring that the angle between laser b and laser a located outside the outer shell 1 is 180 degrees. Since the angle between the plane lens 8 and the axis of the first light-emitting aperture 10 is 45°, and the first cylinder 5 is parallel to the laser emitted by the laser emitter 2, the direction of the laser a remains unchanged during the process of the plane lens 8 being moved by the first cylinder 5, only a translation occurs.
[0024] As a preferred embodiment, the outer casing 1 is provided with a first groove 12, the length of which is parallel to the light emitted by the laser emitter 2. The left and right ends of the first frame 7 are slidably connected between the two ends of the first groove 12, and the connecting line between the left and right ends of the first frame 7 is parallel to the axis of the second light-emitting hole 11. The first frame 7 is sealed to the inner wall of the first groove 12 around the second light-emitting hole 11 by an opaque elastic rubber 13. This arrangement prevents light from outside the outer casing 1 from entering the first plane mirror 3 and the second plane mirror 4 and affecting laser a and laser b.
[0025] In a preferred embodiment, the light emitter includes a second frame 14 and a third planar reflector 15. The second frame 14 has a second light inlet 16 and a third light outlet 17. The axis of the second light inlet 16 is parallel to the light emitted by the laser emitter 2, and the axis of the third light outlet 17 is perpendicular to the axis of the second light inlet 16. The angle between the axis of the third planar reflector 15 and the axis of the second light inlet 16 is 45°. The reflecting surface of the third planar reflector 15 faces the inner bottom wall of the outer casing 1. One end of the third light outlet 17 extends outside the outer casing 1. The free end of the piston rod of the second cylinder 6 is fixedly connected to the outer top of the second frame 14. With this configuration, the laser b can be adjusted by the second cylinder 6 to allow the product to move while maintaining its direction, thus adapting to different needs. Furthermore, the laser a and laser b can be collinear by adjusting the second cylinder 6. Since the angle between the axis of the third plane mirror 15 and the axis of the second light inlet 16 is 45°, and the piston rod of the second cylinder 6 is parallel to the light emitted by the laser emitter 2, the movement of the third plane mirror 15 driven by the second cylinder 6 will not affect the direction of the laser b, but will only cause the laser b to be translated.
[0026] As a preferred embodiment, the outer casing 1 is provided with a second sliding groove 18, the length line of which is parallel to the light emitted by the laser emitter 2. The left and right ends of the second frame 14 are slidably connected between the two ends of the second sliding groove 18, and the connecting line between the left and right ends of the second frame 14 is parallel to the axis of the third light-emitting hole 17. The second frame 14 is sealed to the inner wall of the second sliding groove 18 around the third light-emitting hole 17 by an opaque elastic rubber 13. The use of the opaque elastic rubber 13 serves two purposes: firstly, it prevents dust from entering the outer casing 1 without affecting the movement of the second frame 14; secondly, it prevents other light from entering the outer casing 1 and affecting lasers a and b.
