When in use, the suction plate 3 is connected with a flip structure 301 to flip the external material to the position between the limit plates 2. At this time, the light source emitted by the internal detection visual system 102 can completely cover the material on the suction plate 3 to complete the subsequent inspection. In order to meet the needs of more materials, a reverse threaded rod 5 is provided at the bottom of the two sets of limit plates 2, and threads in opposite directions are provided on both sides of the reverse threaded rod 5. The limiting plates 2 are symmetrically arranged on both sides of the suction plate 3, and the bottom of the limiting plates 2 are fixedly connected with adjustment sleeves 501, so that the adjustment sleeves 501 are respectively threadedly connected to the two sides of the reverse threaded rod 5, and the reverse threaded rod 5 and the turning handle 502 are an integrated structure design. The reverse threaded rod 5 is controlled to rotate by the turning handle 502, driving the adjustment sleeves 501 on both sides to move away from the suction plate 3 and closer to the end of the suction plate 3, thereby driving the limiting plates 2 to move in the same direction, so as to appropriately adjust the spacing of the fixed materials, improve the operational convenience, and also meet the fixing needs of more materials to ensure applicability.

[0037] A fixed bracket 6 is also provided in the present application. The bottom of the fixed bracket 6 is in contact with the surface of the working area plate 101. The fixed bracket 6 can be fixed to the working area plate 101 by bolts. One end of the reverse threaded rod 5 is horizontally movably installed on the side wall of the fixed bracket 6 through a bearing to fix the reverse threaded rod 5 as a whole. Among them, the reverse threaded rod 5 and the fixed bracket 6 and other structures are located directly behind the limit plate 2 and the suction plate 3.

[0038] A carrier plate 4 is also provided in this application. The carrier plate 4 is arranged at the door of the visual inspection body 1, so that the limit plate 2, suction plate 3 and flip structure 301 are located on it, which is fixed and convenient for operation. The carrier plate 4 is installed on the working area plate 101.

[0039] The present application also provides a built-in slot 7 and a stabilizing plate 701. The built-in slot 7 is opened at the rear part of the carrier plate 4. The stabilizing plate 701 is fixedly installed at the front end of the stabilizing plate 701 and can extend to the internal movement of the built-in slot 7. Therefore, when the position of the adjustment sleeve 501 is adjusted, the stabilizing plate 701 can be relatively driven to move in the same direction inside the built-in slot 7, thereby performing a positioning operation on the moving adjustment sleeve 501 to ensure its stability during the movement.

[0040] A sliding rod 801 is also provided in the present application.

[0041] In the present application, an external frame 8 is also provided. Two groups of external frames 8 are provided, which are located at the two ends of the opening of the built-in slot 7 and are fixedly installed at the corresponding positions on both sides of the outer wall of the carrier plate 4, so that the parts of the two ends of the slide rod 801 extending out of the built-in slot 7 are installed on the inner wall of the external frame 8, thereby supporting the slide rod 801 on the carrier plate 4.

[0042] The present application also provides a mounting assembly, which is mainly composed of a mounting opening 302, a mounting rod 9, a positioning sleeve 901 and a positioning end plate 905. The mounting opening 302 is provided at one end of the flip structure 301 connected to the suction plate 3, wherein the mounting opening 302 is a T-shaped design, and the smaller end can pass through the inside of the flip structure 301. The mounting rod 9 and the positioning end plate 905 are an integrated structural design, and the mounting rod 9 can be passed through the inside of the mounting opening 302 from top to bottom, and the positioning end plate 905 will install the mounting rod 9 on the top The position is limited to the larger end of the mounting opening 302, and the end of the mounting rod 9 extending out of the mounting opening 302 is provided with an external thread, which matches the internal thread of the flip structure 301. At this time, the fixing mounting rod 9 rotates the flip structure 301 and connects it to the thread at the thread, which can limit the lower position of the mounting rod 9, so that the connection between the suction plate 3 and the flip structure 301 is located between the positioning end plate 905 and the positioning sleeve 901, so that the suction plate 3 is installed on the upper end surface of the flip structure 301. This design makes it convenient to disassemble the suction plate 3 at any time for its replacement.

[0043] In this application, an outer pressure ring 902 and a stabilizing ring gasket 904 are also provided. The outer pressure ring 902 is fixedly installed on the upper end of the outer ring of the positioning sleeve 901. When the flip structure 301 is rotated to connect with the installation plug rod 9, the outer pressure ring 902 can be pressed tightly against the bottom of the flip structure 301, thereby increasing the area of ​​the connection of the positioning sleeve 901. At the same time, the stabilizing ring gasket 904 is glued to the outer pressure ring 902 and is designed to be made of rubber. When the outer pressure ring 902 is pressed tightly against the flip structure 301, the friction of the contact surface can be increased, making the connection more stable. The above can further ensure the stability of the positioning sleeve 901 during the installation process.

[0044] A handle 903 is also provided in the present application. The handle 903 is fixedly mounted on the bottom of the positioning sleeve 901 to facilitate the rotation of the positioning sleeve 901, thereby bringing convenience to the operation process.

[0045] A stabilizing bottom ring 906 is also provided in this application. The stabilizing bottom ring 906 is designed with rubber material and is glued to the bottom of the positioning end plate 905 so as to contact the groove in the upper part of the mounting opening 302. In this way, when the positioning end plate 905 restricts the mounting rod 9 inside the mounting opening 302, the tightness of the connection can be increased, making the upper connection more stable.
