[0002] Printed glass is a kind of decorative glass that forms a pattern on the glass surface through special processes. It is made by coating a layer of colored fusible inorganic glaze on the glass surface through techniques such as screen printing and inkjet printing, and after heating or toughening treatment, it forms a colored glaze glass with stable and lasting color, acid and alkali resistance, and semi-transparency. The printing methods include screen printing, digital printing, etc. It is generally used in the following aspects: Building facades: Printed glass is often used in building facades to create unique visual effects through different patterns and transparency changes; Interior decoration: Such as partitions, screens, doors and windows, etc. Printed glass is favored for its unique artistry and decorativeness; Commercial spaces: Such as shopping malls, hotels and other places, printed glass can be used to create a specific atmosphere and brand image.

[0003] Visual inspection is an automated inspection method that uses machine vision technology for measurement and judgment. Visual inspection is to use a machine to replace the human eye for measurement and judgment. Through machine vision products, namely image acquisition devices, which are divided into CMOS and CCD types, the target to be captured is converted into an image signal and transmitted to a dedicated image processing system. According to information such as pixel distribution, brightness, and color, it is converted into a digital signal; the image system performs various operations on these signals to extract the features of the target, and then controls the actions of on-site equipment according to the discrimination results. The characteristics of visual inspection are to improve the flexibility and automation degree of production. In some dangerous working environments that are not suitable for manual operation or occasions where manual vision is difficult to meet the requirements, machine vision is often used to replace manual vision; at the same time, in the process of large-scale industrial production, it is inefficient and inaccurate to use manual vision to inspect product quality. Using the machine vision inspection method can greatly improve production efficiency and the degree of production automation. The typical structure includes: lighting, lens, camera, image acquisition card, and vision processor; in industrial production, visual inspection can be used to identify problems such as appearance defects and dimensional deviations of products, improve product quality and production efficiency. In the medical field, visual inspection can be used for medical image analysis, disease diagnosis, etc., to assist doctors in making more accurate diagnoses and treatments. In the security monitoring field, visual inspection can be used for face recognition, behavior analysis, etc., to improve security prevention capabilities. In the intelligent transportation field, visual inspection can be used for traffic flow monitoring, license plate recognition, etc., to optimize traffic management and planning.

A conveyor belt 2 is arranged in the transportation groove. A plurality of glass samples 9 are placed on the conveyor belt 2. A plurality of fixing columns 5 are fixedly connected to the upper end of the workbench 1. A top frame 6 is fixedly connected to the upper ends of the plurality of fixing columns 5. A visual detection device 7 is fixedly connected to the lower end of the top frame 6. A plurality of legs 3 are fixedly connected to the lower end of the workbench 1. A push plate 8 is arranged on one side of the workbench 1. The lower end of the push plate 8 abuts against the upper end of the workbench 1. The conveyor belt 2 is flush with the notch of the transportation groove. The push plate 8 is connected to the side wall of the workbench 1 through a driving device. The driving device includes a fixed platform 4 fixedly connected to the side wall of the workbench 1. Two fixed seats 16 are fixedly connected to the upper end of the fixed platform 4. Electric push rods 15 are fixedly connected to the upper ends of the two fixed seats 16. The extending ends of the two electric push rods 15 are fixedly connected to the side wall of the push plate 8. Anti-slip lines are arranged on the side wall of the push plate 8 away from the electric push rods 15. The anti-slip lines can prevent unnecessary slippage of the glass sample 9 when pushing the glass sample 9.

[0024] Among them, a groove is penetrated through the other side wall of the workbench 1 at a position symmetrical to the push plate 8. A blanking plate 10 is fixedly connected in the groove. A blanking slope is penetrated through the blanking plate 10. A connecting plate 17 is fixedly connected to the side wall of the workbench 1. The other end of the connecting plate 17 is fixedly connected to a collection box 11. Through grooves are penetrated through the front and rear side walls of the collection box 11. Two tracks 12 are arranged in the through grooves. An intercepting device is penetrated through the side wall of the collection box 11 at the corresponding position. The intercepting device includes a groove penetrated through the side wall of the collection box 11. A rotating motor 18 is fixedly connected in the groove. An intercepting rod 19 is fixedly connected to the end of the output shaft of the rotating motor 18. The intercepting rod 19 is located at the notch of one through groove. A limiting block 20 is fixedly connected to the side wall of the collection box 11. The limiting block 20 is located below the intercepting rod 19 and abuts against it. The limiting block 20 can limit the position of the intercepting rod 19 and prevent excessive displacement of the intercepting rod 19.

[0025] Specifically, a plurality of material frames 13 are slidably arranged at two tracks 12, and a collecting device is arranged in each of the plurality of material frames 13. The collecting device includes a bottom plate 14 arranged in the material frame 13. The lower end of the bottom plate 14 is elastically connected to the inner bottom of the material frame 13 through two springs 21. A trigger sensor body 22 is fixedly connected to the inner bottom of the material frame 13 at the corresponding position. The trigger sensor body 22 is a related trigger sensing device in the prior art and can be triggered by pressure to send a signal to drive related devices once. This is the prior art and will not be elaborated here. Buffer cotton is arranged on the inner wall of the collecting frame 11, the upper end of the bottom plate 14, and the inner wall of the material frame 13. A discharge chute is penetrated through the side wall of the material frame 13, and a plug board 23 is slidably arranged at the notch of the discharge chute. A handle is fixedly connected to the outer side wall of the plug board 23.

[0026] In the present invention, the conveyor belt 2 on the workbench 1 operates under the drive of a related driver in the prior art, and can drive a plurality of glass samples 9 to move forward on the workbench 1. When the conveyor belt 2 drives the glass samples 9 to move below the corresponding vision detection device 7, the vision detection device 7 is mainly a vision camera that can identify defects. This is the prior art and will not be elaborated here. If the vision detection device 7 detects a defective product, it can drive two electric push rods 15 through a linkage device in the prior art. The two electric push rods 15 will drive the push plate 8 to push the unqualified glass samples 9. The glass samples 9 will be pushed by the push plate 8 from the conveyor belt 2 to a groove on one side. The anti-slip lines arranged on the side wall of the push plate 8 can provide anti-slip when contacting the glass samples 9, preventing the glass samples 9 from slipping during the movement and causing them to fail to enter the blanking plate 10 in the groove.

[0027] The glass samples 9 pushed to the blanking plate 10 will slide into the collecting frame 11 through the blanking slope and finally enter the material frame 13 in the collecting frame 11 and finally fall onto the upper end of the bottom plate 14. At this time, the buffer cotton on the side wall of the collecting frame 11, the side wall of the material frame 13, and the upper end of the bottom plate 14 can prevent the glass samples 9 from colliding and breaking. After the bottom plate 14 receives the glass samples 9, the springs 21 can be compressed and deformed. When a plurality of glass samples 9 are stacked on the upper end of the bottom plate 14 and finally trigger the corresponding trigger sensor body 22, the trigger sensor body 22 will drive the corresponding rotating motor 18 to rotate through a signal transmission in the prior art. The rotating motor 18 will drive the corresponding intercepting rod 19 to lift up. At the same time, it will also drive the track 12 to operate through a related driving device in the prior art, and can drive the material frame 13 to move and leave the corresponding collecting frame 11 through the track 12, allowing a new material frame 13 to enter the collecting frame 11 to form a blanking cycle.
