Description

Technical Field

DETAILED DESCRIPTION

[0054] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0055] like Figures 1 to 9 As shown, a calibration device for a galvanometer motor includes a base 1, a reflective lens 2 and a driving member 3; a focusing lens 4 is provided on the base 1, a calibration object 5 is provided at one end of the base 1, and a light input portion 6 is provided at the other end; the base 1 is also provided with a mounting portion for mounting a galvanometer motor 7; the reflective lens 2 is connected to the output shaft of the galvanometer motor 7, and is used to reflect the light source passing through the light input portion 6; the driving member 3 is used to drive the reflective lens 2 or the output shaft of the galvanometer motor 7 to rotate, so that the reflective lens 2 rotates around the output shaft axis of the galvanometer motor 7 to adjust the focal position of the light source passing through the light input portion 6; the calibration object 5 has a target 1 8 and a target 2 9 separated by a first distance, and a target 3 10 located between the target 1 8 and the target 2 9.

[0056] like Figures 1 to 5 As shown, in this embodiment, a light source is externally disposed. The light enters the calibration device through the light input portion 6, is reflected by the reflective lens 2, and is focused on the focusing lens 4, thereby forming a focal point on the calibration object 5. During calibration, the galvanometer motor 7 is first assembled onto the base 1. Then, the driver 1 3 is adjusted so that the light source focuses on the target 3 10. The intermediate potential is recorded. The driver 1 3 is then adjusted so that the light source focuses on the target 1 8. The limit potential 1 at the limit position 1 is recorded. The light source is then focused on the target 2 9. The limit potential 2 at the limit position 2 is recorded. Finally, the galvanometer motor 7 is removed from the base 1 to complete the calibration operation. Clearly, this embodiment has the advantages of convenient and accurate operation.

[0057] In this embodiment, a connecting member 11 is also included, and the connecting member 11 is connected to the output shaft of the reflective lens 2 and / or the galvanometer motor 7; the power end of the driving member 3 is connected to the connecting member 11 in transmission connection. Furthermore, a clamp 12 is also included, one end of the clamp 12 is connected to the reflective lens 2, and the other end is used to connect to the output shaft end of the galvanometer motor 7; the connecting member 11 is connected to the clamp 12. The clamp 12 can ensure the connection stability between the reflective lens 2 and the output shaft of the galvanometer motor 7, and is simple and easy to assemble. On the basis of the mutual connection between the connecting member 11 and the clamp 12, the transmission connection between the driving member 3 and the reflective lens 2 is realized, thereby realizing rapid calibration. In this embodiment, in order to further facilitate disassembly and assembly, and ensure connection stability, the clamp 12 is connected to the end face of the output shaft of the galvanometer motor 7. The reflective lens 2 can be connected to the clamp 12 in a variety of ways, and maintain good connection stability. As Figure 7As shown, in one embodiment, the fixture 12 has a clamping wall 13 and a clamping wall 14 that are parallel to each other. One end of the reflective lens 2 is placed between the clamping wall 13 and the clamping wall 14 and bonded to the clamping wall 13 and the clamping wall 14. In this embodiment, the two side surfaces of the reflective lens 2 are bonded to the clamping wall 13 and the clamping wall 14 respectively. Figure 8 As shown, in one embodiment, the clamp 12 has a clamping wall 13 and a clamping wall 14 at an open angle, and a driving member 15 for driving the clamping wall 13 and the clamping wall 14 to open or close. In this embodiment, the clamping wall 13 and the clamping wall 14 are opened and closed by the driving member 15. Generally speaking, the driving member 15 can be configured as a mating part of a screw and a nut. With the clamping wall 13 as a reference, the nut is located on the side of the clamping wall 14 away from the clamping wall 13. Therefore, rotating the nut can move the clamping wall 14 closer to or away from the clamping wall 13, thereby realizing the disassembly and assembly of the reflective lens 2. Figure 9 As shown, in one embodiment, the clamp 12 includes a first clamping wall 13 and a second clamping wall 14 that form a closed angle. In this embodiment, the bases of the first and second clamping walls 13, 14 are deformable, meaning that the first and second clamping walls 13, 14 are elastically connected to the main body of the clamp 12. Therefore, the clamping force generated by the first and second clamping walls 13, 14 effectively clamps the reflective lens 2. In this embodiment, bonding can also be performed simultaneously.

[0058] In this embodiment, the driving member 1 3 is a motor or a telescopic rod mechanism or a screw threadedly connected to the base 1. Figure 1 and Figure 4 As shown, as a preferred embodiment, the driving member 3 is a screw threadedly connected to the base 1. Specifically, the end of the screw abuts against the connecting member 11, so that in the process of twisting the screw, the screw can drive the connecting member 11 to flip forward or reverse, thereby realizing the angle adjustment of the reflective lens 2.

[0059] like Figures 1 to 5In this embodiment, a clamp 16 is further included. The clamp 16 is used to clamp the output shaft of the galvanometer motor 7. The clamp 16 is movably connected to the mounting base to position the galvanometer motor 7 in the mounting portion. A washer 17 is disposed between the clamp 16 and the galvanometer motor 7. The clamp 16 and the mounting base each have a positioning hole, and the mounting base has a positioning post 18 that mates with the positioning hole. Therefore, after the clamp 16 clamps the washer 17 and is mounted on the galvanometer motor 7, the galvanometer motor 7 and the mounting base are positioned and installed, thereby aligning the central axis of the galvanometer motor 7 with the central axis of the mounting portion and maintaining the positioning reference. The washer 17 can be adjusted in the axial direction of the galvanometer motor 7, thereby adjusting the relative position between the connector 11 and the clamp 12. It is understood that to ensure rotational stability, a mating surface, a key structure, or a pin structure is provided between the connector 11 and the clamp 12 to further ensure rotational stability.

[0060] like Figures 1 to 6As shown, in this embodiment, a quick-release mechanism is also included for positioning and installing the galvanometer motor 7 on the mounting portion of the base body 1. The quick-release mechanism includes a fixing seat 19, a support member 20, and a connecting rod mechanism 21. The fixing seat 19 is connected to the base body 1. The support member 20 is used to abut the galvanometer motor 7 to fix the galvanometer motor 7 to the mounting portion. One end of the connecting rod mechanism 21 is hinged to the fixing seat 19, and the other end is movably connected to the support member 20. In this embodiment, the quick-release mechanism can tighten the galvanometer motor 7 in the mounting portion, avoiding the use of fixing members, thereby improving assembly efficiency. In this embodiment, the connecting rod mechanism 21 has a handle. By pulling or pressing the handle, the support member 20 can press the galvanometer motor 7. Furthermore, the support member 20 is a rod-shaped structure. The connecting rod mechanism 21 includes an assembly portion, and a sliding hole 22 is provided on the assembly portion. The support member 20 and the sliding hole 22 are slidably connected. During assembly, the connecting rod mechanism 21 is in a relaxed state, so that the relative position of the support member 20 in the slide hole 22 can be adjusted. Once the position is determined, the connecting rod mechanism 21 can be driven by the handle to be in a compressed state, thereby completing the positioning assembly of the galvanometer motor 7. Furthermore, the support member 20 is provided with an engaging mechanism for fixing the support member 20 at any position in the slide hole 22. Specifically, the engaging mechanism includes a component 1 23 and a component 2 24, as well as a nut 1 25 and a nut 2 26; the component 1 23 and the component 2 24 are movably provided on the shaft portion of the support member 20, for engaging the assembly portion between the component 1 23 and the component 2 24; the nut 1 25 and the nut 2 26 are respectively provided on the side away from each other of the component 1 23 and the component 2 24, and the nut 1 25 and the nut 2 26 are threadedly connected to the support member 20. After the relative position of the support member 20 in the slide hole 22 is determined, the support member 20 is fixed in the slide hole 22 by using the engaging mechanism, so as to prevent the support member 20 and the assembly part from being displaced relative to each other during the operation of the handle, thereby affecting the positioning and installation effect of the galvanometer motor 7. The above structure is simple and easy to operate, and only two nuts need to be tightened or loosened.

[0061] The above are merely preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the claims. Persons skilled in the art will appreciate that improvements and modifications may be made without departing from the spirit and scope of the present invention, and such improvements and modifications shall also be considered within the scope of protection of the present invention.
