Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0024] Example 1

[0025] Reference Figures 1-3 A user-friendly laser scanning galvanometer motor includes a terminal block 2, a rear body 3, and a front body 31. The front body 31 is mounted on the front end of the rear body 3. The terminal block 2 is mounted on the upper end of the rear body 3 and is electrically connected to an external controller via a connecting wire. A field lens 6 is mounted on the inner front end of the front body 31, allowing light to pass through. A galvanometer entrance hole 5 is located on the inner right side of the front body 31, allowing external light to pass through and enter the inner parts of both the rear and front bodies 31. The front body 31 has an X-axis scanning galvanometer mechanism 1 installed on the inner side of its upper end, which can effectively reflect the incoming light. The front body 31 has a Y-axis scanning galvanometer mechanism 4 installed on the inner side of its left end. The Y-axis scanning galvanometer mechanism 4 can reflect the light reflected by the X-axis scanning galvanometer mechanism 1. The X-axis scanning galvanometer mechanism 1 and the Y-axis scanning galvanometer mechanism 4 can be adjusted to reflect light at different angles. The X-axis scanning galvanometer mechanism 1, the Y-axis scanning galvanometer mechanism 4 and the terminal 2 are electrically connected by a connecting wire, so that they can be connected and used accordingly.

[0026] The X-axis scanning galvanometer mechanism 1 includes a first motor 10, a mounting plate 11, a first lens 12, a connecting arm 13, a first coupling 14, and a mirror cleaning mechanism 7. The first motor 10 is mounted on the upper middle of the mounting plate 11, and the mounting plate 11 is screwed onto the front body 31, allowing the mounting plate 11 to be placed stably. The output end of the first motor 10 passes through the mounting plate 11 and is mounted on the first coupling 14. The connecting arm 13 is mounted on the lower end of the first coupling 14. When the output end of the first motor 10 rotates, it can drive the first coupling 14 to rotate, and the first coupling 14 can drive the connecting arm 13 to rotate. The first lens 12 is mounted on the inner end of the connecting arm 13. When the connecting arm 13 rotates, it can drive the first lens 12 to rotate by an angle. The mirror cleaning mechanism 7 is mounted on the rear side of the first lens 12 on the mounting plate 11. The mirror cleaning mechanism 7 can blow gas to absorb dust on the surface of the first lens 12, preventing the first lens 12 from affecting accuracy when reflecting light.

[0027] In this utility model, the mirror cleaning mechanism 7 includes a lead screw slider 71, a lead screw body 15, a lead screw motor 16, a hollow panel 17, a bottom end plate 18, and a hollow plate 19. The lead screw body 15 is arranged on the inner side of the lower end of the bottom end plate 18, and the upper end of the bottom end plate 18 is fixed to the mounting plate 11 for stable placement. The internal lead screw of the lead screw body 15 is connected to the output end of the lead screw motor 16 via a coupling. The lead screw slider 71 is rotatably connected to the circumferential thread of the internal lead screw of the lead screw body 15. The output end of the lead screw motor 16 rotates... The internal screw of the screw mechanism 15 can be rotated. When the internal screw of the screw mechanism 15 rotates, the screw slider 71 connected by the thread can be moved effectively. An air plate 19 is installed on the outer end of the screw slider 71. The screw slider 71 can drive the air plate 19 to move. A hollow panel 17 is installed on the inner end of the air plate 19. The air plate 19 generates negative pressure suction from the outside. Then, the negative pressure suction passes through the hollow panel 17 to adsorb the surface dust of the first lens 12, so as to avoid the dust on the first lens 12 affecting the reflection accuracy.

[0028] The adsorption length of the hollow panel 17 is greater than that of the first lens 12, thus making the adsorption more comprehensive and efficient.

[0029] The mounting plate 11 and the front body 31 are connected by screws, which allows them to be installed and fixed in place. Rubber pads are placed at the connection points to make the connection even tighter and more secure.

[0030] In this invention, the mirror cleaning mechanism 7 is connected to the external fan pipe via a rubber hose. The negative pressure suction generated by the external fan pipe can be transmitted to the mirror cleaning mechanism 7, thereby allowing external dust to be adsorbed through the mirror cleaning mechanism 7.

[0031] In this utility model, the rear body 3 and the front body 31 are provided with mounting cavities, which can be used for wrapping and protection.

[0032] Example 2

Compared with the first embodiment, the Y-axis scanning galvanometer mechanism 4 includes a screw mounting plate 41, a second motor 42, an assembly end post 43, a second lens 44, and a second coupling 45. The second motor 42 is mounted on the inner side of the outer end of the screw mounting plate 41. The screw mounting plate 41 is screwed and connected to the front body 31. The second motor 42 can be correspondingly mounted and placed through the screw mounting plate 41. The output end of the second motor 42 passes through the screw mounting plate 41 and is fixedly connected to the second coupling 45. The inner end of the second coupling 45 is fixedly connected to the assembly end post 43. The inner end of the assembly end post 43 is fixedly connected to the second lens 44. When the output end of the second motor 42 rotates, it can drive the second coupling 45 to rotate. When the second coupling 45 rotates, it can drive the assembly end post 43 to rotate. The assembly end post 43 can drive the second lens 44 to change its angle, thereby adjusting and changing the angle to reflect light.

[0034] Working principle: During use, external light enters the rear body 3 and the front body 3 through the galvanometer light entrance hole 5 on the inner right side of the front body 31. An X-axis scanning galvanometer mechanism 1 is installed on the inner upper part of the front body 31, which can effectively reflect the incoming light. A Y-axis scanning galvanometer mechanism 4 is installed on the inner left side of the front body 31, which can reflect the light reflected by the X-axis scanning galvanometer mechanism 1. The X-axis scanning galvanometer mechanism 1 and the Y-axis scanning galvanometer mechanism 4 can be adjusted to reflect light at different angles into the field mirror 6, so that light can pass through for use. In the overall reflected light, the X-axis scanning galvanometer mechanism 1, the Y-axis scanning galvanometer mechanism 4 and the terminal 2 are electrically connected by a connecting wire, and the terminal 2 is electrically connected to an external controller by a connecting wire, so that it can be operated and controlled by the external controller.
