[0023] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0024] like Figure 1 and Figure 2 As shown, an optical image sorting machine according to one embodiment of the present invention includes a feeding device and a sorting device. The feeding device includes a storage cylinder 1 and a feeding assembly 2, which is mounted on the storage cylinder 1 and has a discharge port. The sorting device includes a rotating disk 3, a centering structure 4, a detection assembly 5, a dispensing assembly 6, and a sorting assembly 7. The centering structure 4, the detection assembly 5, and the dispensing assembly 6 are spaced apart on the circumferential periphery of the rotating disk 3. The centering structure 4 includes a centering seat 41 that can be raised and lowered relative to the rotating disk 3. The bottom of the centering seat 41 and the top of the rotating disk 3 cooperate to form a limiting channel. The discharge port faces the limiting channel. The sorting assembly 7 is mounted on the rotating disk 3 and is used to transfer profiles from the rotating disk 3 to the dispensing assembly 6.

[0025] The aforementioned optical image sorting machine includes a storage cylinder 1 for collecting and placing profiles to be sorted; a feeding component 2 for transferring profiles from the storage cylinder 1 to the rotating disk 3; a limiting channel to keep profiles fed from the discharge port within a circle of the same radius around the rotating disk 3, ensuring that the acquisition positions and angles of subsequent optical images of multiple profiles are the same, reducing errors in the acquisition results and improving the accuracy of detection and sorting; and a sorting component 6 to allow operators to control the sorting component 7 to transfer profiles of different types to the sorting component 6 after they have been detected and marked by the detection component 5, thus completing the profile sorting operation.

[0026] like Figure 1 and Figure 2 As shown, in one embodiment, the optical image sorting machine further includes a feeding platform 8 and a sorting platform 9 disposed on one side of the feeding platform 8. The feeding device is fixed on the feeding platform 8, and the sorting device is fixed on the sorting platform 9.

[0027] like Figure 1 and Figure 2As shown, in one embodiment, the feeding assembly 2 includes a feeding plate 21, a discharging plate 22, and a support frame 23 fixed on the feeding platform 8. The feeding plate 21 is mounted on the storage cylinder 1 and has a feeding port. One end of the discharging plate 22 is connected to the feeding plate 21, and the other end of the discharging plate 22 has a discharging port. An inclined seat 24 is mounted on the top of the support frame 23, and the discharging plate 22 is detachably mounted on the inclined seat 24. Specifically, the discharging plate 22 is inclined, so that the profile on the discharging plate 22 can automatically be discharged from the discharging port and transferred to the rotating disk 3 under the action of gravity.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, a rotary motor is installed on the screening table 9, and a rotating disk 3 is mounted on the output end of the rotary motor. A detection ring plate 31 is fitted around the outer periphery of the rotating disk 3. The detection ring plate 31 is made of a transparent material. The transparent material facilitates observation and image processing of the profile on the detection ring plate 31 from the bottom.

[0029] like Figure 2 As shown, in one embodiment, a limiting groove 42 is provided at the bottom of the middle seat 41, and the groove opening of the limiting groove 42 and the plate surface of the detection ring plate 31 cooperate to form a limiting channel for the profile to pass through.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the detection component 5 includes a bottom detection structure and several side detection structures. The bottom detection structure includes a bottom acquisition camera 51 that can be raised and lowered relative to the screening table 9, with the acquisition direction of the bottom acquisition camera facing the bottom of the detection ring plate 31. The side detection structures include side acquisition cameras 52 that can be raised and lowered relative to the screening table 9, with the side acquisition cameras 52 disposed on one side of the detection ring plate 31. Thus, both the bottom acquisition camera 51 and the side acquisition camera 52 can move up and down, allowing them to repeatedly approach the profile, thereby adjusting the acquisition distance and improving the accuracy of optical image detection.

[0031] Furthermore, both the bottom acquisition camera 51 and the side acquisition camera 52 are communicatively connected to an external image acquisition host. This facilitates the collection and classification of optical image information for each profile.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, both the bottom detection structure and the side detection structure include an adjustment handle 53, which is used to control the height position of the bottom acquisition camera 51 and the height position of the side acquisition camera 52, respectively.

[0033] like Figure 1 and Figure 2As shown, in one embodiment, the material distribution component 6 includes multiple spaced-apart material distribution structures, each including a material distribution pipe 61 and a collection pipe 62. The material distribution pipe 61 is vertically mounted on the screening table 9, with a material distribution port 611 at its top and extending to the bottom of the screening table 9, connecting with the collection pipe 62. Profiles are transferred from the detection ring plate 31 to the material distribution port 611, and then flow into the collection pipe 62 for storage, facilitating subsequent recycling of the screened and classified profiles.

[0034] like Figures 1-3 As shown, in one embodiment, the screening component 7 includes a rotating member 71, a first adjusting arm 72, a second adjusting arm 73, a connecting arm 74, a clamping member 75, and a base 76 mounted at the center of the rotating disk 3. The rotating member 71 is mounted on the base 76 and can rotate relative to the base 76. The first adjusting arm 72 is rotatably connected to the rotating member 71, the second adjusting arm 73 is rotatably connected between the first adjusting arm 72 and the connecting arm 74, and the clamping member 75 is rotatably assembled on the connecting arm 74. This design offers very high precision, enabling minute movements and suitable for high-precision processing, assembly, and sorting operations.

[0035] like Figure 3 As shown, in one embodiment, the screening component 7 further includes a drive structure 77, which includes a drive motor, a transmission gear, and a driven gear. The drive motor is mounted on the base 76, and its output end is connected to the transmission gear. The transmission gear meshes with the driven gear, which is connected to the rotating component 71. By providing the drive motor, the drive motor controls the rotation of the transmission gear, thereby controlling the rotation of the driven gear through the meshing state between the transmission gear and the driven gear. This, in turn, controls the rotation state of the rotating component 71, thereby adjusting the clamping position of the clamping component 75.

[0036] The aforementioned screening component 7 is controlled manually by staff or automatically by automated equipment after each profile is classified and marked. The automated equipment is connected to an external image acquisition host, which is existing technology and will not be described in detail.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
