The base 110 can be a frame structure, fixedly connected to the sorting bracket, and the fixing connection method can be bolt connection, etc.
[0024] Support part 111, such as Figure 1 , Figure 2 As shown, a horizontal camera 200 can be horizontally mounted. Four support portions 111 can be provided, extending vertically, with their lower ends fixed to a sorting bracket. The fixing method can be bolt connection. The support portions 111 of the base 110 extend upwards from the bottom. A crossbeam can be provided in the middle of the support portion 111, and a groove can be provided in the middle of the crossbeam. The horizontal camera 200 can be mounted in the groove. The horizontal camera 200 can be fixedly mounted in the groove, and the fixing method can be screws, clips, etc.
[0025] pallet section 112, such as Figure 1 , Figure 2As shown, it can be installed above the support 111. The tray 112 can connect to the two support brackets 111 and can extend along the horizontal direction of the horizontal camera 200. A vertical camera adjustment device 120 and a vertical camera 300 can be installed above the tray 112, and a lens frame adjustment device 130, a lens frame 140, and a dichroic mirror can be installed below the tray 112.

A track groove can be provided above the tray 112 along the horizontal direction of the horizontal camera 200, allowing the vertical camera 300 adjustment device to slide along the track groove.
[0026] Vertical camera adjustment device 120, such as Figure 1 , Figure 2 As shown, a vertical camera adjustment device 120 is slidably mounted above the support plate 112 and can be used to vertically position the vertical camera 300 and adjust its position relative to the horizontal camera 200. The vertical camera adjustment device 120 is located above the support plate 112 and is equipped with a sliding mechanism, allowing it to slide relative to the support plate 112 along a track groove on the support plate 112. Multiple adjustment blocks can be arranged in front of and behind the vertical camera adjustment device 120, and adjustment bolts can be provided on the adjustment blocks to precisely adjust the horizontal displacement of the vertical camera adjustment device 120.

[0027] Frame adjustment device 130, such as Figure 1 , Figure 2 As shown, it can be fixedly installed below the support plate 112. The frame adjustment device 130 can be used to support and position the frame 140. It can be installed below the support plate 112 and fixedly installed by means of pin connection, bolt connection, etc., which can ensure good positioning accuracy and good stability of the connection. The frame adjustment device 130 can adjust the tilt angle of the frame 140 relative to the horizontal camera 200.
[0028] Frame size 140, such as Figure 1 , Figure 2As shown, the frame 140 can be tilted and positioned at the lower part of the frame adjustment device 130, and can be used to fix the dichroic mirror. The frame adjustment device 130 can be used to adjust the tilt angle of the frame 140 relative to the horizontal camera 200. The dichroic mirror can be fixedly mounted on the frame 140. The dichroic mirror can be inserted into the frame through a slot on the frame 140, or it can be fixed to the frame 140 by adhesive placement. The frame 140 can be tilted and positioned at the lower part of the frame adjustment device 130, and its tilt angle can be adjusted according to the position of the vertical camera 300 above. The tilt angle of the frame 140 relative to the horizontal camera 200 can be adjusted by the frame adjustment device 130, which can ensure that the dichroic mirror on the frame 140 can reflect and transmit light from the material to the horizontal camera 200 and the vertical camera 300 respectively, thereby ensuring the accuracy of the coupling result between the horizontal camera 200 and the vertical camera 300.
[0029] In this embodiment, a camera adjustment device 100 is provided, wherein the vertical camera adjustment device 120 can adjust the position and angle of the vertical camera 300 relative to the horizontal camera 200 with high precision, and the lens frame adjustment device 130 can adjust the tilt angle of the lens frame relative to the horizontal camera 200. This ensures that the dichroic mirror on the lens frame 140 can reflect and transmit the light of the material to the horizontal camera 200 and the vertical camera 300 respectively, thereby ensuring the accuracy of the coupling results of the two cameras, improving the accuracy and reliability of material sorting, and increasing sorting efficiency.
[0030] In some embodiments, such as Figure 2 As shown, the frame 140 may include: a frame body 141 and a mounting shaft 142;
[0031] The frame 141 has a circular groove in its center for mounting a dichroic mirror. Two mounting shafts 142 are horizontally positioned on either side of the frame 141, with top plates at their ends. The depth of the circular groove in the center of the frame 141 can be adjusted according to the thickness of the dichroic mirror, ensuring the mirror doesn't easily wobble or shift after installation and facilitating future replacement and maintenance. The frame 141 can be made of stainless steel, aluminum alloy, or other materials with high strength, hardness, and long lifespan. The mounting shafts 142 can be made of high-strength alloy material and are horizontally positioned on either side of the frame 141. Top plates extend outward from both ends of the mounting shafts 142, with the center of each top plate fixed to the mounting shaft 142. The plane of the top plate can face the horizontal camera 200.
[0032] The frame adjustment device 130 may include: a frame support 131 and an adjustment screw 132.
[0033] Eyeglass frame 131, such as Figure 1 As shown, it can be fixedly installed below the support plate 112. The frame bracket 131 can be made of high-strength, corrosion-resistant alloy material, which has high reliability and durability. The frame bracket 131 can be installed below the support plate 112, and the frame bracket 131 can be provided with pin holes, which can be conical. The frame bracket 131 can be fixed to the support plate 112 by means of conical pins, which can improve the positioning accuracy of the frame bracket 131.
[0034] Adjust set screw 132, as follows Figure 1 , Figure 2 As shown, the adjusting screw 132, which can be installed on the frame bracket 131, can be used to push the top plate, causing the mounting shaft 142 to rotate and adjust the tilt angle of the frame relative to the horizontal camera 200. Multiple adjusting screws 132 can be installed on the side wall of the frame bracket 131, close to the horizontal camera 200. The adjusting screw 132 can be a fine-threaded screw to improve adjustment accuracy. When adjusting the tilt angle of the frame 140 relative to the horizontal camera 200, the adjusting screw can be directly adjusted from the position close to the camera, without needing to go through other complex parts of the device, thus improving adjustment efficiency. The adjusting screw 132 can move axially, achieving precise control of the tilt angle of the frame 140. When the adjusting screw 132 is rotated, due to the transmission action of the thread, the adjusting screw 132 can generate a forward or backward thrust along the axial direction. This thrust can directly act on the top plate, which, as the end structure of the mounting shaft 142, is tightly connected to it. When the top plate is pushed by the set screw, it will rotate around the mounting shaft 142, thereby driving the frame 140 to rotate synchronously, thus realizing the adjustment of the tilt angle of the frame 140 relative to the horizontal camera 200. The small gap between the top plate and the side wall of the frame bracket 131 allows the frame 141 to adjust the tilt angle within a small range, which can improve the efficiency of angle adjustment.
[0035] In this embodiment, an adjusting screw 132 can be provided on one side of the frame adjusting device 130. The adjusting screw 132 can push the top plate at the end of the mounting shaft 142, causing the mounting shaft 142 to rotate, thereby causing the frame 140 to rotate synchronously. The tilt angle of the frame 140 relative to the horizontal camera 200 can be adjusted with high precision and effectively, improving adjustment efficiency and accuracy, thereby improving the efficiency and accuracy of material sorting.
[0036] In some embodiments, such as Figure 2As shown, the mounting shaft 142 may be provided with a shoulder 143, which can mate with the frame bracket 131 to restrict the axial movement of the mounting shaft 142. The shoulder 143 can be integrally formed with the mounting shaft 142 and can be an annular protrusion on the mounting shaft 142. The outer diameter of the shoulder 143 is larger than the outer diameter of the mounting shaft 142. When the mounting shaft 142 is installed in the corresponding mounting hole of the frame bracket 131, the shoulder 143 can mate with the end face of the frame bracket 131. When the mounting shaft 142 is subjected to axial force, the shoulder 143 can bear and distribute the force to the frame bracket 131, thereby ensuring that the mounting shaft 142 will not be displaced axially. In this embodiment, by providing a shoulder 143 on the mounting shaft 142, the shoulder 143 cooperates with the frame bracket 131. During the frequent angle adjustments of the vertical camera 300 during shooting, the mounting shaft 142 can always maintain the correct axial position under the synergistic effect of the shoulder 143 and the frame bracket 131. This avoids problems such as tilting of the frame 140 and inaccurate camera shooting caused by the displacement of the mounting shaft 142. It can ensure that the two cameras can acquire images of the same area, thereby improving the shooting accuracy and the accuracy and reliability of sorting.
[0037] In some embodiments, the frame bracket 131 may be provided with a conical pin hole, which allows the frame bracket 131 to be fixed to the underside of the support plate portion 112 by means of a conical pin. The conical pin hole on the frame bracket 131 allows the frame bracket 131 to be positioned under the support plate portion 112 by means of a conical pin. During the insertion of the conical pin hole, the conical pin can automatically align itself, enabling the frame bracket 131 and the support plate portion 112 to quickly and accurately achieve positioning, greatly reducing the debugging time and labor costs during installation. It also effectively restricts the rotation of the frame bracket 131 radially. In this embodiment, fixing the frame bracket 131 to the underside of the support plate portion 112 through the conical pin hole and conical pin ensures a reliable connection between the frame bracket 131 and the support plate portion 112, avoiding problems such as frame 140 shaking and dichroic mirror displacement caused by loose connections. This ensures that the camera adjustment equipment continuously outputs high-quality and stable shooting effects, improving the accuracy and efficiency of material sorting.
[0038] In some embodiments, such as Figure 2 As shown, the adjusting set screw 132 may include: a first adjusting set screw 1321, a second adjusting set screw 1322, a third adjusting set screw 1323 and a fourth adjusting set screw 1324.
[0039] The first adjusting screw 1321 can be installed on the frame bracket 131, with one end abutting against the upper part of the top plate on one side. The first adjusting screw 1321 can be used to push the top plate, and rotation of the mounting shaft 142 can increase the angle between the frame 140 and the support plate 112. The second adjusting screw 1322 can be installed on the frame bracket 131, and can be vertically arranged side by side below the first adjusting screw 1321. One end can abut against the lower part of the top plate on the same side as the first adjusting screw 1321. The second adjusting screw 1321 can be used to push the top plate, and rotation of the mounting shaft 142 can decrease the angle between the frame 140 and the support plate 112. The first adjusting screw 1321 and the second adjusting screw 1322 can be arranged side by side, or can be respectively arranged on both sides of the mounting shaft 142. One of the first adjusting screw 1321 and the second adjusting screw 1322 can be used, or both can be used simultaneously. The first adjusting screw 1321 is located on the upper side of the top plate. When the angle between the lens frame 140 and the support plate 112 needs to be increased, the first adjusting screw 1321 can be rotated. The first adjusting screw 1321 can push the top plate, and the top plate drives the mounting shaft 142 to rotate. The lens frame 140 follows the mounting shaft 142 to rotate away from the support plate 112. The second adjusting screw 1322 is located on the lower side of the top plate. When the angle between the lens frame 140 and the support plate 112 needs to be decreased, the second adjusting screw 1322 can be rotated. The second adjusting screw 1322 can push the top plate, and the top plate drives the mounting shaft 142 to rotate. The lens frame 140 follows the mounting shaft 142 to rotate closer to the support plate 112. The first adjusting screw 1321 and the second adjusting screw 1322 can also cooperate to adjust the tilt angle of the lens frame 140 relative to the horizontal camera 200.
[0040] The third adjusting screw 1323 can be installed on the frame bracket 131, with one end abutting against the upper part of the top plate on the other side. The third adjusting screw 1323 can be used to push the top plate, and the rotation of the mounting shaft 142 can increase the angle between the frame 140 and the support plate 112. The fourth adjusting screw 1324 can be installed on the frame bracket 131, and can be vertically arranged side by side below the third adjusting screw 1323, with one end abutting against the lower part of the top plate on the same side as the third adjusting screw 1323. The fourth adjusting screw 1324 can be used to push the top plate, and the rotation of the mounting shaft 142 can decrease the angle between the frame 140 and the support plate 112. The third adjusting screw 1323 and the fourth adjusting screw 1324 can be arranged side by side, or can be respectively arranged on both sides of the mounting shaft 142, corresponding to the first adjusting screw 1321 and the second adjusting screw 1322. The third adjusting screw 1323 can be located on the upper side of the top plate, and the fourth adjusting screw 1324 can be located on the lower side of the top plate. The third adjusting screw 1323 can push the top plate along with the first adjusting screw 1321, and the top plate drives the mounting shaft 142 to rotate, so that the frame 140 can stably follow the mounting shaft 142 to rotate away from the support plate 112. The fourth adjusting screw 1324 can push the top plate along with the second adjusting screw 1322, and the top plate drives the mounting shaft 142 to rotate, so that the frame 140 can stably follow the mounting shaft 142 to rotate closer to the support plate 112 without deviation.
[0041] In this embodiment, by setting the first adjusting top screw 1321 and the second adjusting top screw 1322 to be arranged side by side and adjusted bidirectionally, the accuracy of the tilt angle adjustment of the lens frame 140 can be improved. The third adjusting top screw 1323 and the fourth adjusting top screw 1324 are correspondingly set with the first adjusting top screw 1321 and the second adjusting top screw 1322, which can improve the stability of the tilt angle adjustment of the lens frame 140, improve the adjustment accuracy, improve the coupling accuracy of the two cameras, and improve the accuracy and reliability of material sorting.
[0042] In some embodiments, such as Figure 2 As shown, a crossbeam can be provided in the middle of the support part 111, and a groove can be provided in the middle of the crossbeam for horizontally fixing the horizontal camera 200. The crossbeam can be provided in the middle of the support part 111, and the horizontal camera 200 can be horizontally set in the groove in the middle of the crossbeam. The groove can be set according to the contour of the horizontal camera 200, so that the horizontal camera 200 can be stably placed in the groove, which can prevent the horizontal camera 200 from shaking. The horizontal fixing method of the horizontal camera 200 can be bolts, clips, etc., which can facilitate disassembly and replacement. In this embodiment of the present disclosure, fixing the horizontal camera 200 horizontally in the groove in the middle of the crossbeam allows the lens frame 140 to be adjusted only according to the position and angle of the vertical camera 300, which can save the adjustment operation of the lens frame 140, improve the adjustment efficiency, and improve the accuracy of coupling between the two cameras.
[0043] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the vertical camera adjustment device 120 may include: a first movable support 121, a first rotating support 122, a second rotating support 123, and a third rotating support 124.

The first rotating bracket 122 can be rotated around the first rotating axis via a first adjusting bolt, allowing adjustment of the angle of the vertical camera 300 in the XZ plane. The rear wall of the first rotating bracket 122 can be provided with a second rotating shaft hole corresponding to the first rotating shaft hole. Connected to the first movable bracket 121 via the first rotating axis parallel to the Y-axis, the first rotating bracket 122 can be rotated around the first rotating axis by rotating the first adjusting bolt along the X-axis direction to press against the first boss, thereby allowing the vertical camera 300 to rotate in the XZ plane.
