A force balance system is built by the extension and contraction of the spring and the adjusting knob to realize the rotary adjusting function.

[0062] Embodiment 3

[0063] The embodiment is based on the embodiment 2, and the turnover adjusting mechanism 5 is further described as shown in Figures 1-7 The turnover adjusting mechanism 5 comprises a turnover fixing member 51, a turnover spring top block 52 and a turnover adjusting knob 53.

[0064] The turnover fixing member 51 is vertically assembled on the bottom plate 1 and located outside the line structure light source fixing member 41, and the turnover shaft 413 of the line structure light source fixing member 41 is rotatably assembled on the turnover fixing member 51; the turnover fixing member 51 is provided with a vertical turnover adjusting member mounting hole 511, the turnover top block 414 is horizontally inserted into the turnover adjusting member mounting hole 511 and can move up and down therein; the turnover spring top block 52 is assembled at the lower part of the turnover adjusting member mounting hole 511, the turnover adjusting knob 53 is threadedly assembled at the upper part of the turnover adjusting member mounting hole 511 and extends outward, and the turnover top block 414 is located between the turnover spring top block 52 and the turnover adjusting knob 53 and abuts against both.

[0065] In this embodiment, the preset overturning center is arranged in the overturning fixing member 51, and the overturning shaft 413 can rotate around the overturning center. That is, the rotation adjusting mechanism 4 can rotate around the overturning center, and further drives the line structured light source 3 to overturn around the overturning center, so as to realize the overturning adjustment of the line structured light source 3. When the overturning adjustment is performed, the overturning adjusting knob 53 drives the overturning top block 414 to move up and down, and further drives the rotation adjusting mechanism 4 to rotate around the overturning center, so that the line structured light source 3 overturns around the overturning center.

[0068] The overturning adjustment method of the overturning adjusting mechanism 5 in this embodiment can be as follows: first, rotate the rotation adjusting mechanism 4 around the overturning adjustment center, and compress the spring in the overturning spring top block 52 to the extreme. Then, gradually adjust the overturning adjusting knob 53, so that the rotation adjusting mechanism 4 rotates around the overturning center. The line structured light source and the line array camera are evaluated to be coplanar by checking the picture taken by the line array camera. If the picture taken by the line array camera shows that the whole picture is a bright stripe, it indicates that the line structured light source and the line array camera are coplanar at this time. Finally, the screw can be tightened to connect the overturning fixing member and the rotation adjusting mechanism as a whole.

[0069] Embodiment 4

[0070] Based on the above-mentioned embodiment 3, the adjustment method suitable for the line structured light and the line array camera being coplanar is provided. In the adjustment method, the line array camera 2 is fixed, and the line structured light source 3 is adjusted to be collinear with the line array camera 2. The adjustment can be performed by first rotating and then overturning, or by first overturning and then rotating.

[0071] When the first rotation and then overturning, the rotation adjusting mechanism 4 is used to perform the rotation adjustment, and the light emitted by the line structured light source 3 is adjusted to be parallel to the light emitted by the line array camera 2. Then, the overturning adjusting mechanism 5 is used to perform the overturning adjustment, so that the light emitted by the line structured light source 3 coincides with the light emitted by the line array camera 2.

[0072] When the first rotation and then the second rotation, first use the rotation adjustment mechanism 5 for rotation adjustment, adjust the light emitted by the line structured light source 3 to intersect with the light emitted by the line array camera 2; then use the rotation adjustment mechanism 4 for rotation adjustment, convert the intersection state of the light emitted by the line structured light source 3 and the light emitted by the line array camera 2 into the coincident state.

[0073] In this embodiment, the line structured light source and the line array camera are adjusted to be collinear, the line array camera is fixed, and the line structured light source is adjusted to meet the collinear requirement. The adjustment method can be first rotation and then rotation, or first rotation and then rotation.

[0074] The adjustment method is first rotation and then rotation: first adjust the line structured light source to be parallel to the two lines of the line array camera, and then adjust the line structured light source to be coplanar with the line array camera through rotation.

[0075] The adjustment method is first rotation and then rotation: first adjust the line structured light source to be parallel to the two lines of the line array camera, and then adjust the line structured light source to be coplanar with the line array camera through rotation.

[0076] Before rotation adjustment and rotation adjustment, according to the working distance, paste the corresponding target at the corresponding position, the target has continuous equidistant black and white stripes, and the corresponding scale table is set at both ends of the target.

[0077] In order to facilitate the adjustment of the line structured light source and the line array camera coplanar, the light and dark stripe target is designed, and the corresponding scale lines are designed on the left and right sides of the target. The scale line can judge whether the line structure is parallel to the horizontal surface.

[0078] The adjustment method of this embodiment is further described below, which includes the following steps:

[0079] S1, rotation adjustment

[0080] S11, rotate the rotation adjustment knob 45, the rotation adjustment knob 45 drives the rotation top block 43 to move downward, drives the line structured light source 3 to rotate around the rotation center, and the rotation top block 43 simultaneously compresses the rotation spring top block 44;

[0081] S12, when the spring inside the rotation spring top block 44 is compressed to the extreme, reverse rotate the rotation adjustment knob 45, under the lifting force of the rotation spring top block 44, drive the rotation top block 43 to move upward, make the line structured light source 3 reverse rotation around the rotation center;

[0082] S13, when the bright stripe on the target and the black and white stripes are perpendicular, stop rotating the rotation adjustment knob 45, and use the rotation movement fixing piece 46 to fix the line structured light source 3 and the line structured light source fixing piece 41.

[0083] The above rotation adjustment method first connects the line structured light source rotation adjustment ring, the line structured light source, and the rotation top block into a whole through a screw; then rotates the whole to compress the spring inside the spring top block to the extreme, and then rotates the rotation adjustment knob to realize the rotation of the line structured light source around the rotation center. A force balance system is constructed through the extension and retraction of the spring and the adjustment knob to realize the rotation adjustment function. When the bright stripes of the line structured light source on the target are perpendicular to the black and white stripes, it indicates that the rotation adjustment has been completed, and the screw at the bottom of the rotation line structured light source fixing part is rotated to make the line structured light source and the line structured light source fixing part integral.

[0084] The line structured light source fixing part 41 of the embodiment is provided with a rotation center for rotation adjustment, a line structured light source fixing waist hole, an adjustment knob mounting hole, a spring top block mounting hole, and the like. The mounting hole of the spring top block is a threaded hole matched with a locking screw, and the rotation adjustment angle range can be adjusted by rotating the locking screw. The line structured light source fixing waist hole is convenient for fixing the line structured light source and the line structured light source fixing part as a whole after the line structured light source rotates around the rotation center.

[0085] S2, flip adjustment

[0086] S21, rotate the flip adjustment knob 53, the flip adjustment knob 53 drives the flip top block 414 to move downward, drives the line structured light source 3 to rotate around the flip center, and makes the line structured light source located below the straight line where the line array camera 2 is located. The flip top block 414 simultaneously compresses the flip spring top block 52;

[0087] S22, after the spring inside the flip spring top block 52 is compressed to the extreme, the flip adjustment knob 53 is reversely rotated, and under the lifting force of the flip spring top block 52, the flip top block 414 is driven to move upward, and the line structured light source 3 is reversely rotated around the flip center;

[0088] S23, during the reverse rotation, the line structured light gradually approaches the straight line where the line array camera is located, and stops rotating the flip adjustment knob 53 when the two coincide with each other;

[0089] S24, use the line array camera 2 to take pictures, view the pictures taken by the line array camera 2, and evaluate whether the line structured light source 3 and the line array camera 2 are coplanar; if the line array camera takes pictures and the whole picture is bright stripes, the line structured light source and the line array camera are coplanar, otherwise continue to adjust the line structured light source 3;

[0090] S25, after the line structured light source 3 and the line array camera 2 are coplanar, the line structured light source fixing part 41 and the flip fixing part 51 are fixed by using the flip motion fixing part 54.

[0091] In the above flip adjustment method, the main goal of flip adjustment is to make the linear structured light source which has been parallel to the target to be coplanar with the linear array camera through flip adjustment. The flip adjustment mechanism mainly converts the linear motion of the flip adjustment knob into the rotary motion of the rotary adjustment mechanism around the flip center through the flip adjustment knob, spring top block, etc., and then realizes the coplanar operation. During adjustment, first rotate the rotary adjustment mechanism (as a whole) around the flip adjustment center, and compress the spring inside the spring top block to the extreme, then adjust the flip adjustment knob step by step, so that the rotary adjustment rotates around the flip center. Rotate the flip adjustment knob to compress the spring to the extreme, at this time the rotary adjustment mechanism will rotate along the flip adjustment center, so that the linear structured light is parallel to the mounting surface, and through this step adjustment, the linear structured light is located below the straight line where the linear array camera is located, then rotate the flip adjustment knob in the opposite direction, and the rotary adjustment mechanism rotates around the flip adjustment center in the opposite direction through the spring force, while the linear structured light gradually approaches the straight line where the linear array camera is located, until they coincide with each other. By checking the picture taken by the linear array camera, it can be evaluated whether the linear structured light source and the linear array camera are coplanar. If the picture taken by the linear array camera shows that the whole picture is a bright stripe, it means that the linear structured light source and the linear array camera are coplanar at this time. Finally, the screw can be tightened to connect the flip fixing part and the rotary adjustment mechanism as a whole.

[0092] The flip adjustment is to rotate the rotary adjustment mechanism around the flip adjustment center through the spring top block, flip adjustment knob and flip fixing part, so that the linear structured light source and the linear array camera are coplanar. By rotating the flip adjustment knob, the flip adjustment knob pushes the rotary adjustment mechanism to move back and forth, and there is a spring top block at the other end of the flip adjustment knob, which constitutes a dynamic force balance. That is, the whole rotary structure can be adjusted to make the linear structured light source and the linear array camera coplanar.
