Abstract
Description
Technical Field
[0001] This utility model relates to the field of camera bracket technology, and in particular to a CCD camera bracket adjustment device. Background Technology
[0002] During the crystal growth process in a single crystal furnace, CCD visual image acquisition and processing technology is required to monitor a series of processes, including constant diameter control of the crystal rod, temperature feedback control, diameter detection, edge breakage detection, and material detection. The CCD camera is installed on the furnace cover to monitor the real-time images of the corresponding areas of the molten metal inside the furnace. Because the monitoring targets and methods of different manufacturers are different, the shape of the furnace cover is different, and the models of the thermal field components are different, the corresponding camera angles are also different.
[0003] Due to the requirements of the crystal growth process, the consistency of CCD camera position has a significant impact on the consistency of CCD liquid level distance measurement and diameter control. The position measurement and adjustment calibration of each single crystal furnace CCD are performed by operators. However, manual operation has a certain degree of error, and the accuracy and consistency of adjustment of each CCD camera cannot be guaranteed. In addition, manual measurement during adjustment takes a lot of time, resulting in low adjustment efficiency. Utility Model Content
[0004] Purpose of the invention: To address the shortcomings of existing camera adjustment methods, such as poor accuracy, inconsistent performance, and low efficiency, this invention provides a CCD camera bracket adjustment device.
[0005] Technical Solution: To solve the above problems, this utility model adopts a CCD camera bracket adjustment device, including an adjustment mechanism and a camera bracket mounted on the adjustment mechanism. The adjustment mechanism includes a first translation stage, a second translation stage, a third translation stage, a first rotation stage, and a second rotation stage. The movement directions of the first translation stage, the second translation stage, and the third translation stage are perpendicular to each other. The first rotation stage and the second rotation stage are used to adjust the rotation angle of the camera bracket. Each of the first translation stage, the second translation stage, the third translation stage, the first rotation stage, and the second rotation stage is equipped with a micrometer and graduation lines.
[0006] Furthermore, the adjustment mechanism also includes an adjustment plate, with the first translation stage mounted on the adjustment plate, the second translation stage mounted on the first translation stage, the third translation stage mounted on the second translation stage, the first rotary stage mounted on the third translation stage, the second rotary stage mounted on the first rotary stage, and the camera bracket mounted on the second rotary stage.
[0007] Furthermore, the axes of rotation of the first and second rotary tables are perpendicular to each other.
[0008] Furthermore, the adjustment plate is provided with waist-shaped holes distributed in a circular pattern.
[0009] Furthermore, the second translation platform is provided with an L-shaped fixing frame, and the third translation platform is installed on the L-shaped fixing frame.
[0010] Furthermore, the first rotating platform is provided with an L-shaped connecting plate, and the second rotating platform is mounted on the L-shaped connecting plate.
[0011] Furthermore, it also includes a base plate and a protective cover. The protective cover and the adjustment mechanism are both installed on the base plate, and the adjustment mechanism is housed inside the protective cover. An opening and closing door is provided on one side of the protective cover.
[0012] Beneficial effects: Compared with the prior art, the significant advantage of this utility model is that it realizes the multi-degree-of-freedom adjustment of the camera by setting up a translation stage and a rotation stage. Each translation stage and rotation stage has a micrometer and a scale line. The micrometer can make the adjustment accuracy reach 0.02mm, and the scale line can ensure the consistency of the adjustment position. It also eliminates the step of manual measurement and improves the adjustment efficiency. Attached Figure Description

[0018] like Figure 1 and Figure 2 As shown, a CCD camera bracket adjustment device in this embodiment includes a base plate 1, a protective cover 2, an adjustment mechanism 3, and a camera bracket 4. The protective cover 2 and the adjustment mechanism 3 are both mounted on the base plate 1, and the adjustment mechanism 3 is housed within the protective cover 2. The camera bracket 4 is mounted on the adjustment mechanism 3. Figure 3 As shown, the entire camera bracket adjustment device is installed on the furnace cover 6.
[0019] like Figure 4 and Figure 5As shown, the adjustment mechanism 3 includes an adjustment plate 31, a first translation stage 32, a second translation stage 33, a third translation stage 34, a first rotary stage 35, and a second rotary stage 36. Each of the first translation stage 32, second translation stage 33, third translation stage 34, first rotary stage 35, and second rotary stage 36 is equipped with a micrometer and graduation lines. The adjustment plate 31 is fixedly mounted on the base plate 1. For ease of description, the long side of the adjustment plate is defined as the X-axis, the short side as the Y-axis, and the direction perpendicular to the plane as the Z-axis. The adjustment plate 31 has four circumferentially distributed oblong holes 311 near its four corners, allowing it to rotate at a certain angle around the Z-axis when fixed to a plane.
[0020] A first translation stage 32 is mounted on an adjusting plate 31, and a second translation stage 33 is mounted on the first translation stage 32. The first translation stage 32 moves along the X-axis, and the second translation stage 33 moves along the Y-axis. An L-shaped fixing frame 38 is provided on the second translation stage 33, and a third translation stage 34 is mounted on the L-shaped fixing frame 38. The third translation stage 34 moves along the Z-axis. A first rotary stage 35 is mounted on the third translation stage 34, and an L-shaped connecting plate 37 is provided on the first rotary stage 35. A second rotary stage 36 is mounted on the L-shaped connecting plate 37, and the first rotary stage 35 rotates about the X-axis, while the second rotary stage 36 rotates about the Y-axis.
[0021] Camera bracket 4 is mounted on the second rotary stage 36, and camera 5 is mounted on camera bracket 4. Three translation stages enable translation of the camera in the X, Y, and Z directions, while two rotary stages enable rotation of the camera in the X and Y axes, thus achieving multi-degree-of-freedom adjustment of the camera. Micrometers installed within each translation and rotary stage allow for adjustment accuracy down to 0.02 mm. The scale lines ensure consistent adjustment positions and eliminate the need for manual measurement, improving adjustment efficiency.
