[0024] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0025] The embodiment of the present invention provides a multi-axis zero position consistency calibration mechanism for an optoelectronic device, such as Figure 1 , Figure 2 As shown, it includes: a first adjustment component 1, a second adjustment component 2 and a fixing component 3;

[0026] The fixing assembly 3 includes a positioning cylinder 31, a rotating shaft 32 and a knob 33. The bottom end of the positioning cylinder 31 is fixed to the optical axis, and the other end (the end opposite to the bottom end) is provided with the rotating shaft 32. The rotating shaft 32 is provided with the knob 33. The knob 33 is adjusted to move and rotate the rotating shaft 32.

[0027] The first adjustment component 1 is connected to one side of the rotating shaft 32, and includes a first sleeve 11, a first fixed shaft 12 and a first locking member 13. One end of the first fixed shaft 12 is connected to one side of the rotating shaft 32. The first sleeve 11 can be slidably mounted on the first fixed shaft 12. The first sleeve 11 is circumferentially provided with a second locking member to fix the first sleeve 11 on the first fixed shaft 12 based on the second locking member. The first locking member 13 can be slidably connected to one end of the first fixed shaft 12. The first locking member 13 is slidably connected to the first fixed shaft 12 to adjust the sliding position of the first sleeve 11 and achieve locking and fixing. In this example, the first sleeve 11 can be used to achieve coarse adjustment of the corresponding calibration direction, and the first locking member 13 can be used to further fine-tune the coarsely adjusted first sleeve 11.

[0028] The second adjustment component 2 is connected to the other side of the rotating shaft 32, and the second adjustment component 2 is coaxial with the first adjustment component 1, and includes a second sleeve 21, a second fixed shaft 22 and a third locking member 23. One end of the second fixed shaft 22 is connected to the other side of the rotating shaft 32. The second sleeve 21 can be slidably sleeved on the second fixed shaft 22. The second sleeve 21 is circumferentially provided with a fourth locking member to fix the second sleeve 21 on the second fixed shaft 22 based on the fourth locking member. The third locking member 23 can be slidably connected to one end of the second fixed shaft 22, and the third locking member 23 is slidably connected to the third fixed shaft 22 to adjust the sliding position of the second sleeve 21 and achieve locking and fixing. In this example, the orientation of the second adjustment component 2 is opposite to that of the first adjustment component 1, and the coarse adjustment of the corresponding calibration direction can be achieved through the second sleeve 21. The third locking member 23 can further fine-tune the second sleeve 21 after coarse adjustment. In some embodiments, the second adjustment component 2 is coaxial with the first adjustment component 1, and the coaxiality is perpendicular to the optical axis connected to the positioning tube 31. Therefore, the zero adjustment mechanism of this embodiment has a large adjustable range of size, can realize coarse adjustment and fine adjustment, and can be used for adjusting the axis of optoelectronic devices of different sizes or specifications.

[0029] The calibration mechanism of the embodiment of the present invention includes a fixed component, a first adjustment component and a second adjustment component, which cooperate with a rotating shaft to realize the zero position consistency calibration of a multi-sensor optoelectronic device. The zero position consistency calibration mechanism of this embodiment has a simple structure, strong practicality, easy operation and a large adjustable range.

[0030] In some embodiments, the second locking member is a locking screw disposed along the circumference of the first sliding sleeve 11; the fourth locking member is a locking screw disposed along the circumference of the second sliding sleeve 21. Figure 1 As shown, three locking screws 111 can be arranged on the circumference of the first sliding sleeve 11, which can be arranged at 120° to each other. Similarly, three locking screws 211 can be arranged on the circumference of the second sliding sleeve 21, which can also be arranged at 120° to each other. The first sliding sleeve 1 can be fixed on the first fixed shaft 12 by tightening the locking screws 111 of the first sliding sleeve 11, and the principle of the second sliding sleeve 21 is similar.

[0031] In some embodiments, a locking screw is disposed on the circumference of the first locking member 13; and a locking screw is disposed on the circumference of the third locking member 23. In some embodiments, four locking screws 131 are disposed on the circumference of the first locking member 13, which can be disposed at 90° to each other. Similarly, four locking screws 231 are disposed on the circumference of the third locking member 23, which can also be disposed at 90° to each other. The first locking member 13 can be fixed to one end of the first fixed shaft 12 by tightening the locking screws 131 of the first locking member 13, and the principle of the third locking member 23 is similar.

[0032] In some embodiments, the first locking member 13 is threadedly connected to one end of the first fixed shaft 12, and the third locking member 23 is threadedly connected to one end of the second fixed shaft 22. Specifically, the first sliding sleeve 11 and the second sliding sleeve 21 are finely adjusted by threading.

[0033] In some embodiments, one end of the first fixed shaft 12 is detachably connected to one side of the rotating shaft 32, and one end of the second fixed shaft 22 is detachably connected to the other side of the rotating shaft 32. Specifically, the detachability can be achieved based on the aforementioned threaded matching method.

[0034] Figure 3A schematic diagram of a multi-optical axis consistency zeroing mechanism 301 installed on a certain multi-sensor optoelectronic device is shown. In this embodiment, the bottom of the positioning cylinder 31 is installed on the optical axis 3 of the target optoelectronic device, ensuring that the axis of the positioning cylinder of the zeroing mechanism is coaxial with the axis of the third optical axis 304. The target optoelectronic device has an equipment housing 300, and the zeroing mechanism 301 is arranged therein. The first optical axis 303 is installed on the left side of the third optical axis 304, and can realize self-rotation and revolution with the third optical axis 304; the second optical axis 302 is installed on a fixed device and can only realize self-rotation. The left end face of the first sliding sleeve 11 abuts against the parts on the first optical axis 303, and the right end face of the second sliding sleeve 21 abuts against the parts on the second optical axis 302. The rotation and movement of the rotating shaft 32 and the first adjustment component 1 and the second adjustment component 2 in the vertical direction (z direction) are achieved by rotating the knob 33. At the same time, the coarse adjustment and fine adjustment of the left end surface of the first sleeve 11 and the optical axis 1 are achieved by adjusting the first sleeve 11 and the first locking piece 13, and the locking and fixing are achieved under the action of the locking screw 111 and the locking screw 131; the coarse adjustment and fine adjustment of the right end surface of the second sleeve 21 and the second optical axis 302 are achieved by adjusting the second sleeve 21 and the third locking piece 23, and the locking and fixing are achieved under the action of the locking screw 211 and the locking screw 231.

[0035] This ultimately enables optical axis consistency debugging and measurement results to be within 5”, thus enabling mechanical calibration of the optical axis on multi-sensor optoelectronic devices.

[0036] The multi-optical axis zero position consistency calibration mechanism of the embodiment of the present application can achieve optical axis adjustment of optoelectronic devices of different sizes and specifications to ensure the consistency of the optical axis through the mutual cooperation between the first adjustment component 1, the first adjustment component 2 and the fixed component 3. The size, spacing and positioning of the calibration mechanism are adjusted according to the size of the optoelectronic device, so as to achieve the purpose of zero position calibration suitable for different optoelectronic devices. The calibration mechanism of this embodiment has the advantages of novel and reasonable structure, strong practicality, large adjustable range, simple and convenient operation, and time-saving and labor-saving.
