Description

Technical Field

[0002] After the production of galvanized sheet is completed, the surface of the galvanized sheet needs to be tested to ensure the quality of the galvanized sheet.

[0003] However, for existing inspection solutions, most of them use multiple cameras to inspect the surface of galvanized sheets. If the camera is installed only by positioning holes, the colinearity problem of multiple cameras is difficult to achieve, which can easily lead to image stitching that is inconsistent with the actual situation. In addition, for camera adjustment, most existing solutions use multi-dimensional adjustment methods, but it is difficult to achieve strict separation and stable locking of the adjustment effects of each dimension during adjustment. It is difficult to lock one dimension without affecting another dimension. The camera angle is mostly a fixed value, and the requirements for on-site construction and installation are very strict. If position offset occurs, this will cause the camera to be out of the pre-designed range, resulting in unclear imaging. Utility Model Content

[0023] Reference Figure 4 The inner cavity of the fixed mounting seat 201 is movably connected with a first rotation center shaft 207, one side of the first rotation center shaft 207 is fixedly connected to the surface of the first adjusted part 202, and the inner cavity of the first adjusted part 202 is movably connected with a second rotation center shaft 208, one side of the second rotation center shaft 208 is fixedly connected to the surface of the second adjusted part 203. Through the setting of the first rotation center shaft 207 and the second rotation center shaft 208, the positions of the first adjusted part 202 and the second adjusted part 203 are supported respectively, so that in the process of adjusting the first fine-tuning micrometer head 205 and the second fine-tuning micrometer head 206, the first adjusted part 202 and the second adjusted part 203 can be driven to rotate around the surfaces of the first rotation center shaft 207 and the second rotation center shaft 208 respectively.

[0024] Reference Figure 5The inner cavities of the fixed mounting seat 201 and the first adjusted member 202 are both equipped with a locking mechanism 3, and the locking mechanism 3 includes a locking groove 302, which is opened in the inner cavities of the fixed mounting seat 201 and the first adjusted member 202, and the inner cavity of the locking groove 302 is equipped with a corrugated spring washer 301, and the inner cavities of the corrugated spring washer 301 and the locking groove 302 are both threadedly connected with a locking bolt 303, and the surface of the locking bolt 303 is respectively connected to the inner cavities of the first adjusted member 202 and the second adjusted member 203. The cavity is threadedly connected, and through the setting of the locking groove 302, the corrugated spring washer 301 can fit into the interior of the fixed mounting seat 201 and the first adjustable part 202, so that through the setting of the corrugated spring washer 301, a pre-tightening force is applied between the shaft end plane and the reference plane to eliminate the influence of other dimensional changes caused by the gap between the first rotation center shaft 207 and the second rotation center shaft 208 and the inner cavity of the fixed mounting seat 201 and the first adjustable part 202, respectively, so as to make the camera 204 more stable.

[0025] Reference Figure 2 A cooling fan 105 is installed at the bottom of the inner cavity of the single camera 104, and the top of the cooling fan 105 is in contact with the bottom of the second adjustable component 203. The setting of the cooling fan 105 increases the heat dissipation efficiency of the camera 204 inside the single camera 104, preventing the camera 204 from overheating after long-term use, thereby causing the camera 204 to malfunction and reducing the service life of the camera 204.

[0026] Working principle: First, adjust the angle of a single camera 204 according to demand, by holding the first fine-tuning micrometer head 205 and rotating it, the rotation of the first fine-tuning micrometer head 205 drives the second adjusted part 203 to rotate, so that the second adjusted part 203 directly connected to the camera 204 is rotated with the second rotation center shaft 208 as the reference, and then hold the second fine-tuning micrometer head 206 and rotate it, the rotation of the second fine-tuning micrometer head 206 drives the second adjusted part 203 to rotate, The first adjustable member 202 indirectly connected to the camera 204 is adjusted in pitch with the first rotation center axis 207 as a reference, so that each dimension of the camera 204 can be adjusted independently. After the dimension of the camera 204 is adjusted, the corrugated spring washer 301 is placed inside the locking groove 302, and the locking bolt 303 is rotated by holding it, and the locking bolt 303 is inserted into the corrugated spring washer 301, the locking groove 302, and the first adjustable member 202 and the second adjustable member 203, so as to adjust the camera 204 in a certain direction. After the adjustment is completed, the angle of the camera 204 is reinforced, and a pre-tightening force is applied between the shaft end plane and the reference plane by setting the corrugated spring washer 301 to eliminate the influence of other dimensional changes caused by the gap between the first rotation center shaft 207 and the second rotation center shaft 208 and the fixed mounting seat 201 and the inner cavity of the first adjusted member 202, making the camera 204 more stable. Then, by fixing the back side of the fixed mounting seat 201 to the inner wall of the single camera 104, the camera 204 can be installed inside the single camera 104. At the same time, based on the adjusted camera 204 as a reference, the remaining cameras 204 are adjusted. The remaining cameras 204 are adjusted in pitch and angle by the first fine-tuning micrometer head 205 and the second fine-tuning micrometer head 206. In this way, the multiple cameras 204 are collinear with high precision. Then, the multiple single cameras 104 are respectively installed inside the frame 101. Finally, the position of each single camera 104 is positioned by the collinear rod 102.
