Description

Technical Field

[0001] The utility model relates to the technical field of laser vibrating lens, in particular to a laser vibrating lens with a dustproof protection structure. Background Art

[0002] Laser galvanometer is a high-precision, high-speed scanning device in the laser industry. It is mainly composed of an XY optical scanning head, an electronic drive amplifier and other structures. That is, the optical scanning head is driven by the signal provided by the computer controller to control the deflection of the laser beam on the XY plane.

[0003] For example, the Chinese utility model patent disclosed by the existing publication number CN209356756U: A laser galvanometer device with co-directional input and output light, the application includes a Y-axis motor reflector, an X-axis motor reflector, a galvanometer housing and a lens adapter plate. At the same time, the galvanometer housing is fixedly set on the lens adapter plate, and the Y-axis motor reflector and the X-axis motor reflector are both set on the galvanometer housing. Therefore, the lens adapter plate in the application should be provided with a lens to achieve laser focusing and play a certain dust-proof role for the cavity in the galvanometer housing. However, the light inlet on the top of the galvanometer housing in the application is an open structure. The external light will float into the galvanometer housing through the light entrance hole, causing dust to accumulate on the surface of the Y-axis motor reflector and the X-axis motor reflector, affecting the reflection of the laser. In addition, the lens is installed in the lens adapter plate, and the contact surface between the lens and the external environment will also absorb a certain amount of dust during use. Therefore, it needs to be cleaned regularly. When cleaning the lens manually, on the one hand, people tend to forget to clean the lens regularly. On the other hand, due to the small angle between the lens and the light exit hole in the lens adapter plate, manual cleaning methods cannot achieve all-round cleaning of the transparent surface.

[0029] A terminal block 11 is fixedly mounted on the bottom of the protective housing 1. The terminal block 11 is electrically connected to an external main controller via a connecting wire. A sealing lens 12 is fixedly mounted in the first mounting groove 3. The front side of the mirror housing 2 is fixedly connected to the output end of the laser generator. With the arrangement of the sealing lens 12, the connection between the mirror housing 2 and the laser generator is sealed to prevent dust from entering the mirror chamber 27 during installation.

[0030] like Figure 2-Figure 6As shown, this is a second embodiment of the present invention, which is different from the first embodiment in that: the motor 7 is electrically connected to the terminal 11 through a connecting wire, the output end of the motor 7 extends through the protective shell 1 to the position below the protective shell 1 and is fixedly installed with a gear 13, and a lens seat 14 is fixedly installed at the bottom of the mounting cylinder 9, a second mounting groove 15 is provided in the lens seat 14, and a screw groove 16 is provided inside the second mounting groove 15, and the mounting cylinder 9 located below the lens seat 14 is also provided with a displacement groove 19, and the mounting cylinders 9 located above and below the displacement groove 19 are also fixedly installed with shaft seats 20, and a connecting shaft 21 is interspersed between the two shaft seats 20. The arrangement of the lens seat 14 can realize the installation and fixation of the lens 17, and the arrangement of the displacement groove 19, the shaft seat 20 and the connecting shaft 21 can realize the installation of the wiping ring 10 and provide conditions for the rotation of the wiping ring 10, the lens 17 is inserted and installed in the second mounting groove 15, and the limit ring 18 is screwed The groove is connected in the screw groove 16, and with the help of the setting of the lens 17, the focusing of the laser and the isolation of the inner cavity of the mirror chamber 27 from the external environment are achieved. A connecting plate 22 is fixedly installed on the outside of the wiping ring 10, and a plurality of tooth blocks 23 are fixedly installed on the outside of the connecting plate 22. A bearing 24 is fixedly installed on one side of the connecting plate 22. A card slot 25 is opened on the top of the wiping ring 10, and a lens wiping cloth ring 26 is carded in the card slot 25. The wiping ring 10 is inserted and installed in the displacement groove 19, and one side of the connecting plate 22 is rotatably installed on the connecting shaft 21 located between the two shaft seats 20 through the bearing 24. The tooth block 23 is meshed with the gear 13. The wiping ring 10 is controlled by the cooperation of the motor 7 and the gear 13 to rotate in the displacement groove 19 with the connecting shaft 21 as the axis, so that it is convenient to wipe the dust on the side of the lens 17 facing the external environment through the lens wiping cloth ring 26.

However, since one side of the lens 17 is in direct contact with the external environment, when in use, dust in the use environment is easy to float and adhere to the surface of the lens 17, thereby affecting the normal projection of the laser in the later stage. Therefore, the motor 7 can be periodically started by an external main controller to make a periodic reciprocating rotation, so that the output end of the motor 7 drives the gear 13 When the wiping ring 10 is in contact with the lens 17, the gear 13 is rotated, and the gear 13 is meshed with the tooth block 23 on the outside of the connecting plate 22, so that the gear 13 drives the connecting plate 22 to rotate on the connecting shaft 21 with the bearing 24 as the axis. As a result, the connecting plate 22 drives the wiping ring 10 to rotate from the displacement groove 19 to the outside of the displacement groove 19. At this time, the wiping ring 10 can wipe the dust on the side of the lens 17 in contact with the external environment through the lens wiping cloth ring 26 clamped on the top. Then, the output end of the motor 7 drives the gear 13 to rotate in the reverse direction, so that the gear 13 controls the connecting plate 22 and the wiping ring 10 to move in the opposite direction and be re-stored into the displacement groove 19, thereby completing the regular and automatic dust cleaning of the lens 17.
