[0038] Reference Figures 1-4 An embodiment of the present application shows a simple split calibration device, which comprises a laser emitting module 21 and a reflecting module. The bottom of the laser emitting module 21 is formed with a support surface 11a, and the laser emitting module 21 emits laser light perpendicular to the support surface 11a. The reflecting module has a mirror surface 22 for reflecting the laser light.

[0039] When calibrating with the simple split calibration device, as shown in Figure 10

[0040] The laser emitting module 21 is placed on the reference surface of the platform 100, and the reference surface of the platform 100 supports the support surface 11a of the laser emitting module; the platform 100 shown in the embodiment is an optical breadboard, and the reference surface of the platform 100 refers to the top surface (mounting surface) of the optical breadboard;

[0041] The reflection module is placed on the component to be calibrated on the platform 100, and the component to be calibrated supports the reflecting surface 22 of the reflection module, and the reflecting surface 22 is exposed from the edge position of the component to be calibrated; in the embodiment, the reflection module only needs to be placed on the component to be calibrated, without the need for screw locking and other operations, and the arrangement is convenient; of course, in other embodiments, further fixation of the reflection module is not excluded; wherein the surface of the component to be calibrated for placing the reflection module is defined as the bearing surface, and the purpose of calibration is to make the bearing surface parallel to the reference surface of the platform 100;

[0042] The laser emitting module 21 and the reflection module are corresponded in the vertical direction, so that the reflection module is located in the laser emitting direction of the laser emitting module 21; the laser emitting module 21 emits laser to the reflecting surface 22 of the reflection module, and the reflecting surface 22 reflects the laser; the deviation between the landing position of the reflected laser and the emitting position of the laser on the laser emitting module 21 is observed, wherein the greater the non-parallelism between the reflecting surface 22 and the reference surface of the platform 100, the greater the deviation between the landing position of the reflected laser and the emitting position of the laser on the laser emitting module 21; then the inclination direction of the reflecting surface 22 relative to the reference surface of the platform 100 is judged, and the component to be calibrated is adjusted until the landing position of the reflected laser coincides with the emitting position of the laser on the laser emitting module 21, which represents that the reflecting surface 22 of the reflection module is parallel to the support surface 11a of the laser emitting module 21, and also represents that the bearing surface of the component to be calibrated is parallel to the reference surface of the platform 100.

[0043] In some embodiments, as shown in Figures 1-4 and Figure 8 ​As shown, the laser emitting module 21 comprises a first housing 11, a support surface 11a is formed on the bottom of the first housing 11, a laser generator 12 for emitting laser is arranged in the first housing 11, and a light exit hole 111 is arranged on the top of the first housing 11 for the laser to exit. Conventionally, the laser generator 12 should be connected with a switch (not shown), which is arranged on the first housing 11, and the switch is used to turn on and off the laser. When calibrating, whether the landing position of the reflected laser is in the light exit hole 111 can be observed, which is easy to observe visually and to determine whether the landing position of the reflected laser coincides with the emitting position of the laser on the laser emitting module 21.

[0044] Preferably, to further facilitate the observation of the deviation between the landing position of the reflected laser and the emitting position of the laser on the laser emitting module 21, a target 115 is arranged on the top of the first housing 11 with the light exit hole 111 as the center. Figure 2 As shown, the first housing 11 is a square box body, and a target 115 is arranged on the top of the first housing 11 with the light exit hole 111 as the center. When the reflecting surface 22 is not parallel to the support surface 11a, the reflected laser will land on the target 115 of the first housing 11, and the target 115 is convenient for the operator to quickly grasp the tilting direction and tilting amplitude of the reflecting surface 22. The target 115 can be a groove on the surface of the first housing 11 or a line drawn on the surface.

[0045] The reflecting module comprises a second housing 21, and the reflecting surface 22 is arranged on the bottom of the second housing 21, and the reflecting surface 22 is the lowest surface of the emitting module 2. In this way, when the reflecting module is placed on the component to be calibrated, the reflecting surface 22 is attached to the bearing surface on the component to be calibrated.

[0046] Preferably, to further flatten the structure of the laser emitting module 21, so that it can be placed in a compact optical system when in use, as shown in the following figure. Figures 5-8 As shown, a reflecting mirror body 13 is arranged in the first housing 11, and the reflecting mirror body 13 is distributed transversely to the laser generator 12, and the reflecting mirror body 13 is arranged below the light exit hole 111 to reflect the laser emitted by the laser generator 12 to the light exit hole 111. In this embodiment, the laser generator 12 emits laser transversely, and the reflecting mirror body 13 is used to change the optical path of the laser, so that the laser is emitted from the light exit hole 111. In this embodiment, the laser generator 12 and the reflecting mirror body 13 are distributed transversely, which is conducive to making the thickness of the first housing 11 thinner, and facilitating the placement of the first housing 11 in the bottom space of some optical and mechanical components.

[0047] In some embodiments, to ensure that the laser emitted by the laser emitting module 21 is perpendicular to the support surface 11a, the first housing 11 is provided with an adjusting mechanism 14 for adjusting the reflection angle of the laser by the mirror body 13.

[0048] Specifically, as shown in Figures 5-7 the adjusting mechanism 14 includes a tray 141 arranged in the first housing 11, the mirror body 13 is arranged on the tray 141, the first housing 11 supports the tray 141 through a fulcrum, the fulcrum is below the mirror body 13; the tray 141 is provided with three adjusting screws 142 arranged from top to bottom, the three adjusting screws 142 are distributed on the outer side of the fulcrum, and the lower end of the adjusting screw 142 is threadedly connected to the first housing 11; the adjusting screw 142 is sleeved with a spring 144, the adjusting screw 142 is provided with an abutting portion 1421 above the tray 141, and the spring 144 is located between the abutting portion 1421 of the adjusting screw 142 and the tray 141.

[0049] Wherein, one end of the spring 144 abuts against the abutting portion 1421, and the other end abuts against the tray 141, the spring 144 presses the tray 141 towards the fulcrum, when the adjusting screw 142 is rotated, the abutting portion 1421 can be raised or lowered, thereby adjusting the elastic force of the spring 144 on the tray 141, and further adjusting the inclination of the tray 141; by adjusting the inclination of the tray 141, the emission direction of the laser by the mirror body 13 can be adjusted, thereby ensuring that the laser emitted from the light emitting hole 111 is perpendicular to the support surface 11a.

[0050] In some embodiments, as shown in Figure 8 the abutting portion 1421 is a screw cap of the adjusting screw 142, the screw cap of the adjusting screw 142 is located inside the first housing 11, the first housing 11 protects the adjusting screw 142 from external interference, and can also increase the aesthetic appearance; when it is necessary to adjust the emission direction of the laser, the first housing 11 is first disassembled, in the present embodiment, the first housing 11 is a square box body including a box body and a box cover, the box cover can be disassembled to expose the screw cap of the adjusting screw 142.

[0051] And in some other embodiments, as shown in Figure 9 the abutting portion 1421 is a structure fixed on the stud of the adjusting screw 142, the screw cap of the adjusting screw 142 is exposed outside the first housing 11, when it is necessary to adjust the emission direction of the laser, the first housing 11 does not need to be disassembled, and the adjustment is convenient.

[0052] The above scheme is specifically, asFigures 6-8 As shown, the fulcrum between the first shell 11 and the tray 141 is a steel ball 143, the first shell 11 is provided with a first clamping hole 114, the bottom of the tray 141 is provided with a second clamping hole 1411, at least part of the steel ball 143 is embedded in the first clamping hole 114, and at least part of the steel ball 143 is embedded in the second clamping hole 1411. In this way, the position of the steel ball 143 is fixed by the first clamping hole 114 and the second clamping hole 1411, avoiding displacement of the steel ball 143 in the first shell 11; the tray 141 can be flipped around the steel ball 143. In this embodiment, the first clamping hole 114 and the second clamping hole 1411 are tapered holes.

[0053] Preferably, before calibrating the component to be calibrated, the laser emission direction of the laser emission module 21 should be detected, and the detection process is as follows:

[0054] The laser emission module 21 is rotated around the light emitting hole 111 as the axis, the axis of the light emitting hole 111 is perpendicular to the support surface 11a, and the laser emission is maintained during the rotation process. The laser is emitted onto an obstruction, such as an indoor ceiling, and the position of the laser spot on the obstruction is observed to determine whether it moves; if the laser spot moves along a circular trajectory on the obstruction, it means that the laser is not perpendicular to the support surface 11a; if the position of the laser spot is observed to be unchanged, it means that the laser is perpendicular to the support surface 11a.

[0055] In some embodiments, in order to facilitate the detection of the laser emission direction, as shown in Figure 3 , Figure 8 or Figure 9 , the bottom of the first shell 11 is recessed with a positioning adjustment hole 112, and the positioning adjustment hole 112 is coaxially arranged with the light emitting hole 111. In the above detection process, the positioning adjustment hole 112 of the first shell 11 can be inserted on a column (not shown), which is fixed in position. When the first shell 11 is rotated, the first shell 11 rotates around the positioning adjustment hole 112, that is, the first shell 11 rotates around the light emitting hole 111.

[0056] In some embodiments, in order to further flatten the structure of the reflection module, so that it can be placed in a compact optical system when in use, as shown in Figure 4 , the second shell 21 is in the form of a plate, and in application, the second shell 21 is placed on the component to be calibrated, as shown in Figure 10As shown, at least part of the second shell 21 should be suspended, so that part of the reflecting mirror 22 is in the direction of the laser emission, and part of the reflecting mirror 22 is in contact with the bearing surface on the component to be calibrated; thus, it is necessary to ensure that the center of gravity of the emission module 2 is in the vertical projection range of the component to be calibrated, so as to avoid the emission module 2 from falling; in the embodiment, the second shell 21 is provided with a counterweight 23, and the counterweight 23 makes the reflecting module have opposite heavy end 2a and light end 2b. When arranging the reflecting module, the heavy end 2a can be placed on the component to be calibrated, and the light end 2b is suspended. By arranging the counterweight 23, even if the volume of the reflecting module is small, the emission module 2 can also be kept stable in the state of being partially suspended, and therefore, the counterweight 23 is beneficial to making the volume of the reflecting module smaller.

[0057] In some embodiments, as Figure 3 As shown, the first shell 11 is provided with a first magnetic block 113, and the second shell 21 is provided with a second magnetic block (not shown), and the first shell 11 and the second shell 21 are magnetically adsorbed and connected through the first magnetic block 113 and the second magnetic block. In the embodiment, the laser emission module 21 and the reflecting module can be fixed together when not in use, which is convenient for transportation and carrying, and can also avoid the laser emission module 21 and the reflecting module from being easily lost; when in use, the reflecting module can be directly pulled out of the laser emission module 21, which is convenient to operate. The first magnetic block 113 / second magnetic block can be embedded in the interior of the first shell 11 / second shell 21, so that the outer appearance is more beautiful, and meanwhile, the first magnetic block 113 / second magnetic block is prevented from falling off and being lost.

[0058] In the above embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0059] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
