Description

Technical Field

[0001] The present invention relates to the technical field of laser attenuation, and in particular to a laser attenuation device and a control method thereof. Background Art

[0002] Laser is a strong light with the characteristics of high brightness, pure color and high energy. It is widely used in various fields such as communication, medical treatment, material processing and electronic imaging. Laser has the characteristics of good coherence, strong directionality and high brightness. However, in the field of laser detection, the intensity of laser signal can easily exceed the response range of the detector, causing the detector to be saturated or even damaged.

[0003] Common methods include using neutral density attenuation sheets to absorb excess light energy, or using beam splitters to reflect part of the light beam to achieve attenuation. When staff debug laser parameters, they need to add, subtract or replace attenuation sheets. Attenuation sheets are generally connected to the laser transmitter in a threaded manner. When staff install the attenuation sheets, they are likely to stand at the transmitting end of the laser transmitter. When the laser transmitter is not turned off, it is easy for the staff to shine into the eyes. Laser entering the eyes may cause adverse consequences to the staff. Summary of the invention

[0024] S4: The seesaw moves on the surface of the roller bar through the sliding frame, and the roller bar is used to limit the seesaw, so that the bottom of the seesaw can pull the lifting plate upward with the movement of the sliding frame.

At this time, the staff can directly pull out the attenuation plate or insert it into the semicircular bracket for replacement.

[0025] The present invention has the following beneficial effects:

[0026] The present invention provides a pressing component on the surface of the laser emitter. When the laser of the laser emitter needs to be attenuated and adjusted, the pressing component is pushed to move downward. At this time, the pressing component will push the protective component to move downward. The laser of the laser emitter is intercepted and shielded by the protective component to prevent the laser from shining into the eyes of the staff when installing the attenuation plate. When the protective component moves downward, it will pull the installation component upward. When the installation component moves upward, it can be separated from the attenuation plate to facilitate the replacement and adjustment of the attenuation plate.

[0027] The staff of the present invention pushes the telescopic plate to move downward through the rubber pad. When the telescopic plate moves downward, the connecting rod pushes the movable frame to slide on the surface of the vertical rod. When the movable frame moves downward, it pushes the protective component to move downward. When the bottom of the telescopic plate contacts the top of the fixed plate, the protective component will shield the output device of the laser transmitter to prevent the laser emitted by the laser transmitter from shining into the eyes of the staff. After the attenuation plate is replaced, the staff releases the telescopic plate, and the movable frame will be reset by the elasticity of the elastic frame and push the protective component to move upward, thereby improving the convenience of operating the protective component and the installation component.

[0028] When the movable frame of the present invention moves downward, the synchronous plate pushes the limit rod to move downward, and when the limit rod moves downward, it pushes the fixed ring and the shielding plate to move synchronously. After the shielding plate corresponds to the laser of the laser transmitter, the laser will be shielded by the shielding plate, so as to avoid the laser shining into the eyes of the staff and causing discomfort when the staff replaces the attenuation plate.

[0029] When the synchronous plate of the present invention moves downward, the sliding frame is pushed by the inclined plate to slide on the surface of the skateboard. When the sliding frame moves, the seesaw plate is pulled to move synchronously. The seesaw plate moves on the surface of the roller rod through the sliding frame, and the roller rod is used to limit the seesaw plate, so that the bottom of the seesaw plate can pull the lifting plate to move upward with the movement of the sliding frame. When the lifting plate moves, it pushes the stabilizing frame to separate from the attenuation plate through the positioning frame. At this time, the staff can directly pull out the attenuation plate or insert it into the interior of the semicircular plug-in frame for replacement, thereby improving the convenience of replacing the attenuation plate. After the staff has completed the debugging of the attenuation plate, they release the pressing component. At this time, the lifting plate will use the elasticity of the elastic rod to push the stabilizing frame to be plugged into the top of the attenuation plate, thereby improving the stability of the attenuation plate after installation.

[0030] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

8. A laser attenuation device according to claim 7, characterized in that: The number of the elastic rods (45) is two, and the two elastic rods (45) are symmetrically arranged with the semicircular frame (44) as the center. A plurality of semicircular inserting frames (42) are arranged inside the semicircular frame (44). The number of the stabilizing frames (46) is the same as the number of the semicircular inserting frames (42). The end of the force-bearing frame (47) extends to the bottom of the sliding frame (32), and the top of the rolling rod (48) contacts the bottom of the rocker (33).

9. The control method of a laser attenuation device according to claim 8, characterized in that: The following steps are involved: S1: A pressing component (3) is provided on the surface of the laser emitter (1). When it is necessary to adjust the attenuation of the laser light emitted by the laser emitter (1), the pressing component (3) is pushed to move downward. At this time, the pressing component (3) pushes the protective component (4) to move downward, and the protective component (4) is used to intercept and shield the laser light emitted by the laser emitter (1); S2: When the telescopic plate (15) moves downward, the movable frame (19) is pushed to slide on the surface of the vertical rod (14) through the connecting rod (17). When the movable frame (19) moves downward, it pushes the protective component (4) to move downward. When the bottom of the telescopic plate (15) contacts the top of the fixed plate (11), the protective component (4) will cover the output device (2) of the laser transmitter (1); S3: When the moving frame (19) moves downward, the limiting rod (36) is pushed downward through the synchronous plate (30), and when the limiting rod (36) moves downward, the fixing ring (34) and the shielding plate (35) are pushed to move synchronously. After the shielding plate (35) corresponds to the laser of the laser transmitter (1), the laser is shielded by the shielding plate (35); S4: The seesaw (33) moves on the surface of the roller (48) through the sliding frame (32), and the roller (48) is used to limit the seesaw (33), so that the bottom of the seesaw (33) can pull the lifting plate (40) to move upward as the sliding frame (32) moves. When the lifting plate (40) moves, it pushes the stabilizing frame (46) to separate from the attenuation plate (43) through the positioning frame (41). At this time, the staff can directly pull out the attenuation plate (43) or insert it into the interior of the semicircular insertion frame (42) for replacement.
