[0001] This utility model relates to the technical field of beam feedback control devices for lasers, and in particular to a beam feedback control device for a radio frequency carbon dioxide laser. Background Technology

[0002] A radio frequency carbon dioxide laser is a type of laser that uses radio frequency energy to excite a mixture of carbon dioxide gases to produce a coherent beam. It is a gas laser that generates laser light based on the stimulated emission of carbon dioxide molecules and is widely used in medicine, military, manufacturing and other fields.

[0003] In the prior art, such as Chinese Patent Publication No. CN 205335611 U, a laser based on an external optical path compensation and adjustment device is disclosed, including a laser, an external optical path compensation and adjustment device, an optical path shaping module, a focusing spherical mirror, and a feedback control module. The feedback control module detects the output laser and adjusts the deflection angle of the deflection mirror to the standard position through the optical path compensation and adjustment system.

[0004] In the prior art, the beam of a traditional radio frequency carbon dioxide laser is limited in its movement angle due to the complex internal structure and mutual constraints between components, resulting in limited beam flexibility. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the beam movement angle of radio frequency carbon dioxide lasers is limited in the existing technology, resulting in limited beam flexibility of radio frequency carbon dioxide lasers, and to propose a beam feedback control device for radio frequency carbon dioxide lasers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a beam feedback control device for a radio frequency carbon dioxide laser, comprising a laser body, a moving component disposed on the outer surface of the laser body, the moving component including a fixed block, a groove formed on the outer surface of the fixed block, a slider slidably connected to the inner wall of the groove, a rotating block fixedly connected to the outer surface of the slider, and a reflector fixedly connected to the inner wall of the rotating block.

[0007] Preferably, the outer surface of the fixed block is fixedly connected to the outer surface of the laser body, and the outer surface of the rotating block is provided with a circular hole.

[0008] Preferably, a rotating shaft is fixedly connected to the outer surface of the rotating block near the center, and a first gear is fixedly sleeved on the outer surface of the rotating shaft near one end.

[0009] Preferably, a shockproof box is provided on the outer surface of the rotating block near the edge, and a shockproof pad is fixedly connected to the inner wall of the shockproof box.

[0010] Preferably, a motor is provided on the outer surface of the shock-absorbing pad, and an output shaft is fixedly connected to the output end of the motor.

[0011] Preferably, a second gear is fixedly sleeved on the outer surface of the output shaft near one end, and the outer surface of the second gear meshes with the outer surface of the first gear.

[0012] Preferably, the outer surface of the laser body is provided with a beam opening, which is located at the center of the fixing block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the device is equipped with a moving component. The motor drives the rotating block to rotate, and the rotating block drives the reflector to rotate. The light from the laser body shines on the reflector through the beam port. The reflector emits the reflected light through the circular hole.

[0015] 2. In this utility model, the device is equipped with a shockproof box. When the motor is started, the motor will vibrate.

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1: As Figures 1-9As shown, this utility model provides a beam feedback control device for a radio frequency carbon dioxide laser, including a laser body 1, a moving component 3 on the outer surface of the laser body 1, the moving component 3 including a fixed block 301, a groove 302 on the outer surface of the fixed block 301, a slider 303 slidably connected to the inner wall of the groove 302, a rotating block 304 fixedly connected to the outer surface of the slider 303, a reflector 305 fixedly connected to the inner wall of the rotating block 304, the outer surface of the fixed block 301 fixedly connected to the outer surface of the laser body 1, a circular hole 306 on the outer surface of the rotating block 304, a rotating shaft 4 fixedly connected near the center of the outer surface of the rotating block 304, a first gear 5 fixedly sleeved near one end of the outer surface of the rotating shaft 4, a second gear 10 fixedly sleeved near one end of the outer surface of the output shaft 9, the outer surface of the second gear 10 meshing with the outer surface of the first gear 5, and a beam opening 2 on the outer surface of the laser body 1, the beam opening 2 being located at the center of the fixed block 301.

[0029] The overall effect of Embodiment 1 is as follows: During the use of a beam feedback control device for a radio frequency carbon dioxide laser, the operator needs to activate the laser body 1 to emit a laser beam. The laser beam is emitted from the beam port 2, hits the outer surface of the reflector 305, and after reflection by the reflector 305, it exits from the circular hole 306 on the rotating block 304. When the operator needs to adjust the angle of the laser beam, the operator can activate the motor 8. The motor 8 drives the output shaft 9 to rotate, which in turn drives the second gear 10 to rotate. The outer surface of the second gear 10 meshes with the outer surface of the first gear 5, thereby driving the first gear 5 to rotate. When the first gear 5 rotates, it drives the rotating shaft 4 to rotate, which in turn drives the rotating block 304 to rotate. The rotating block 304 causes the outer surface of the slider 303 to slide along the inner wall of the groove 302. Simultaneously, the rotating block 304 drives the internal reflector 305 and the outer... The circular hole 306 on the surface rotates, and the angle of the laser beam illuminating the reflector 305 changes as the reflector 305 rotates. Simultaneously, the circular hole 306 rotates along with the reflector 305, so the reflector 305 rotates while simultaneously causing the laser beam to rotate. The laser beam is reflected by the reflector 305 and emitted through the circular hole 306. This device, by incorporating a moving component 3, allows the motor 8 to drive the rotating block 304 to rotate, which in turn drives the reflector 305 to rotate. The light from the laser body 1 shines through the beam port 2 onto the reflector 305, which then reflects the light through the circular hole 306. By rotating the rotating block 304 and the reflector 305, the beam of the radio frequency carbon dioxide laser can be rotated at multiple angles, solving the problem of limited beam movement angle and thus limited beam flexibility in radio frequency carbon dioxide lasers.

[0030] Example 2: As Figures 1-9 As shown, a shockproof box 6 is provided on the outer surface of the rotating block 304 near the edge. A shockproof pad 7 is fixedly connected to the inner wall of the shockproof box 6. A motor 8 is provided on the outer surface of the shockproof pad 7. An output shaft 9 is fixedly connected to the output end of the motor 8.

[0031] The overall effect of Embodiment 2 is as follows: When a beam feedback control device for a radio frequency carbon dioxide laser is in use, the operator starts the laser body 1 to emit a laser beam. The laser beam is emitted from the beam port 2 and hits the outer surface of the reflector 305. After being reflected by the reflector 305, the laser beam is emitted from the circular hole 306 on the rotating block 304. When the angle of the laser beam needs to be adjusted, the operator starts the motor 8. The motor 8 will drive the output shaft 9 to rotate and generate vibration. The vibration is reduced by the vibration box 6 set on the outer surface of the motor 8, thereby reducing the vibration of the motor 8 on the reflector 305 and the laser body 1, and ensuring the accuracy of the movement trajectory of the radio frequency carbon dioxide laser beam.

[0032] Working Principle: In operation, the beam feedback control device for a radio frequency carbon dioxide laser emits a laser beam when the laser body 1 is activated. The laser beam exits from the beam port 2 onto the outer surface of the reflector 305. After reflection by the reflector 305, it exits through the circular hole 306 on the rotating block 304. When the laser beam angle needs adjustment, the motor 8 is activated. The motor 8 drives the second gear 10 to rotate, generating vibration. A vibration damping box 6 is installed on the outer surface of the motor 8 to reduce the vibration impact of the motor 8 on the reflector 305 and the laser body 1. The second gear 10 drives the first gear 5 to rotate, which in turn drives the rotating block 304 to rotate. Block 304 drives the reflector 305 and the circular hole 306 to rotate. As the reflector 305 rotates, it drives the laser beam to rotate as well. The laser beam is reflected by the reflector 305 and emitted through the circular hole 306. This device, by setting the moving component 3, allows the motor 8 to drive the rotating block 304 to rotate. The rotating block 304 drives the reflector 305 to rotate. The light from the laser body 1 shines on the reflector 305 through the beam port 2. The reflector 305 then emits the reflected light through the circular hole 306. By rotating the rotating block 304 and the reflector 305, the beam of the radio frequency carbon dioxide laser can be rotated at multiple angles, thereby improving the flexibility of the radio frequency carbon dioxide laser beam.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
