Figure 3As shown, by rotating the handle 311 on the adjusting seat 31, the screw shaft 312 is driven to rotate, thereby driving the adjusting block 313 threaded with it. Based on the circumferential fixed arrangement of the adjusting block 313 and the adjusting seat 31 itself, the adjusting block 313 will slide along the adjusting seat 31, and the sliding direction is perpendicular to the height of the belt surface of the conveying belt A2. In addition, the height limiting frame 33 and the scraper 32 are fixedly arranged with the adjusting block 313, so that the lifting adjustment of the scraper 32 is also realized during the lifting of the adjusting block 313. In addition, the sliding seat 34 is arranged on the other side of the conveying belt A2, and the sliding block 341 is arranged to slide relative to the sliding seat 34. The structure is basically the same as that of the adjusting seat 31 and the adjusting block 313.

The scraper 32 in this embodiment is the height limiting component for limiting the multi-layer stacked material disc. In general, the distance between the bottom of the scraper 32 and the conveying belt A2 is set to be 1.5 times the thickness of the material disc. This height makes it difficult for double-layer discs to pass through, and in the conveying process, the double-layer discs are scraped off to become single-layer discs.

[0022] As a further arrangement of the above scheme, the visual recognition sensor 5 includes a 2D line scanning camera fixed to the rack 1 and matched with a soft light lamp 51. The fixed position of the visual recognition sensor 5 is located in the rear area of the height limiting device 3 of the conveying belt A2. The visual recognition sensor 5 can scan the bar code on the disc and send the position of the disc with the bar code to the control system of the manipulator 4. In this embodiment, the visual recognition sensor 5 based on machine vision technology plays a very important role. In this embodiment, the 2D line scanning camera of the visual recognition sensor 5 can quickly scan the material disc on the conveying belt A2 and feed back the image information to the control system, so as to obtain whether there is a bar code on the conveying belt A2, and based on the position of the bar code, the disc coordinates are obtained and input to the manipulator 4 and the conveying belt A2 is stopped. The manipulator 4 is used to accurately grasp the disc.

[0023] As a further arrangement of the above scheme, the manipulator 4 includes a control system, a rotating seat 41, a screw telescopic arm 42, and a composite vacuum chuck 43 located at the front end of the screw telescopic arm 42. The control system is used to control the rotating seat 41 to drive the screw telescopic arm 42 to swing between the conveying belt A2 and the conveying belt B6. The screw telescopic arm 42 is used to drive the composite vacuum chuck 43 to switch between the conveying belt A2 and the conveying belt B6.

[0024] As a further arrangement of the above-mentioned scheme, the return box 7 further comprises a slide rail 71 arranged on the machine frame 1, and a track cylinder 72, a piston rod 73 of the track cylinder 72 being connected to the return box 7, for driving the return box 7 to slide on the slide rail 71.

[0025] As a further arrangement of the above-mentioned scheme, the conveying belt A2 is provided with a variable frequency motor 20, the variable frequency motor 20 being electrically connected with the control system of the visual identification sensor 5 and the mechanical arm 4, when the visual identification sensor 5 senses the bar code signal of the optical disc, the variable frequency motor 20 stops working until the mechanical arm 4 picks up the optical disc from the conveying belt A2, the variable frequency motor 20 functions to control the conveying belt A2 to work quickly in linkage with the visual identification sensor 5, so as to fix the position of the optical disc after detection and prevent the optical disc from moving, thereby facilitating the picking up of the mechanical arm 4.

[0026] The sorting device of the embodiment is shown in Figures 1-4 The conveying belt A2 is used for conveying the optical discs to be sorted, and the conveying belt B6 is used for conveying the sorted optical discs to the next process, the mechanical arm 4 for sorting is arranged between the conveying belt A2 and the conveying belt B6, the height limiting device 3 for the optical disc is arranged on the conveying belt A2, the height limiting device 3 functions to limit the second layer and above of the stacked optical discs to pass through, so as to prevent the optical discs from stacking into the rear, it is worth noting that the visual identification sensor 5 is located behind the height limiting device 3, the visual identification sensor 5 comprises a 2D line scanning camera, for scanning the single layer of the optical disc on the conveying belt A2, in the scheme of the embodiment, the visual identification sensor 5 can scan the bar code on the optical disc and send the scanning signal to the control system of the variable frequency motor 20 and the mechanical arm 4, and based on the scanning signal, the variable frequency motor 20 will stop working, so as to stop the conveying of the optical disc with the bar code, and based on the scanning signal of the optical disc and the position of the visual identification sensor 5, the rotary seat 41 and the screw telescopic arm 42 jointly act to make the composite vacuum suction cup 43 adhere to the surface of the corresponding optical disc with the bar code, so as to adsorb and move the optical disc to the conveying belt B6.

[0027] It is worth noting that in the scheme of the embodiment, the conveying on the conveying belt A2 includes but is not limited to the optical disc, as long as the bar code is not scanned, the visual identification sensor 5 will not trigger the mechanical arm 4 and other devices, and the conveying belt A2 will not stop, therefore, it will fall into the return box 7 along with the conveying of the conveying belt A, the return box 7 is provided with the slide rail 71 and the track cylinder 72, after the equipment is shut down, the worker can operate the piston rod 73 of the track cylinder 72 to extend or retract, so as to make the return box 7 close to the opening and closing door of the front of the equipment, thereby facilitating the worker to process the materials in the return box 7.
