The adjustment unit 234 adopts a ball screw transmission structure, so that the lifting seat 233 can be accurately adjusted and positioned along the guide column 232, and the position of the camera 235 can be adjusted more conveniently. The camera positions and directions of the three groups of visual inspection components 23 are different, and the products on the turntable can be photographed and inspected from different directions to ensure the inspection accuracy.

[0053] The material discharge channel 24 is installed on the workbench 12, and its inlet is set toward the turntable 21. The qualified product material selection component 25 is fixedly installed on the top of the material discharge channel 24, and includes a horizontal plate 251, a vertical plate 252, a pad 253, a solenoid valve 254, and an air blowing pipe 255. One end of the horizontal plate 251 is connected to the top of the material discharge channel 24, and the other end extends to the top of the turntable 21. The vertical plate 252 is fixedly connected to the end of the horizontal plate 251 and extends downward. The pad 253 is fixedly installed at the lower end of the side of the vertical plate 252 and maintains a certain inclination angle. The solenoid valve 254 is fixedly installed on the pad 253, and its inlet end is connected to the air source, and the outlet end is connected to the air blowing pipe 255. The air blowing pipe 255 faces the edge of the turntable 21 and corresponds to the inlet of the material discharge channel 24. When the solenoid valve 254 is opened, the air blowing pipe 255 can blow out gas and blow the product into the material discharge channel 24.

[0054] The unqualified product storage bin 26 is also installed on the workbench 12, and a feed port is formed on a side wall thereof facing the turntable 21. The unqualified material shifting assembly 27 is installed on the top of the unqualified product storage bin 26, and is used to deliver the unqualified products on the turntable 21 into the unqualified product storage bin 26. The structural principle of the unqualified material shifting assembly 27 is basically the same as that of the qualified product shifting assembly 25, and therefore will not be described in detail here.

[0055] After the product enters the screening assembly 2, it will be transported by rotating the turntable 21. When the turntable 21 passes through the visual inspection component 23, multiple groups of visual inspection components 23 can take photos of the product from various angles for inspection. If the product is qualified, when the product passes through the qualified product material selection component 25, the qualified product material selection component 25 will blow the qualified product into the discharge channel 24, and directly send it to the back film packaging assembly 3 through the discharge channel 24 for packaging. If the product is unqualified, when the product passes through the unqualified material selection component 27, the unqualified material selection component 27 will blow the unqualified product into the unqualified product storage bin 26 for storage.

[0056] The back-seal packaging assembly 3 is arranged in the lower space 112 of the frame 1 and installed on the mounting bracket 13, and is used for automatic packaging of products. It includes a film feeding component 31, a bag forming device 32, a sealing component 33, and a material receiving component 34.

[0057] The film feeding assembly 31 is installed on the front side of the mounting bracket 13, and includes a film feeding bracket and an unwinding roller and a guide roller on the film feeding bracket. The rolled packaging bag film can be placed on the unwinding roller and actively unwound by a motor drive.

[0058] The bag making and forming device 32 is installed on the front side of the mounting bracket 13 and is located below the film feeding assembly 31. The bag making and forming device 32 has a large opening at the upper end and a small opening at the lower end, and is funnel-shaped. Its upper opening corresponds to the outlet of the discharge channel 24. The packaging bag film in the film feeding assembly 31 is coated on the outside of the bag making and forming device 32 and is sealed by a sealing mechanism to surround it to form a packaging bag.

[0059] The sealing assembly 33 corresponds to the bag making and forming device 32, and includes a back sealing module and an end sealing module, which are respectively used for automatic heat sealing of the back and end of the packaging bag. The back sealing module is fixedly mounted on the front side of the mounting bracket 13 and is correspondingly arranged on one side of the bag making and forming device 32, and can longitudinally seal the packaging bag film wrapped outside the bag making and forming device 32. The end sealing module is correspondingly arranged below the bag making and forming device 32, and can transversely seal the ends of the packaging bag film wrapped outside the bag making and forming device 32, and finally form a closed packaging bag.

[0060] The material receiving assembly 34 is arranged below the bag making and forming device 32, and is used to support the packaging bag filled with materials, and can hold the packaged products to prevent the products in the packaging bag from being too heavy and pulling and damaging the film or packaging bag, thereby affecting the packaging quality.

[0061] The qualified product material-selecting component 25 in the screening assembly 2 can blow the qualified products into the feeding channel 24, and directly send them into the packaging bag wrapped outside the bag-making device 32 through the feeding channel 24. The number of products is consistent with the number of actions of the qualified product material-selecting component 25. When a specified number of qualified products fall into the packaging bag, the back-sealing packaging assembly 3 is actuated to seal the packaging bag, and at the same time a new packaging bag is formed to receive the product.

[0062] By adopting the above scheme, the optical screening assembly and the back-seal packaging assembly are respectively arranged in the upper and lower spaces of the rack, and the two are combined into an integral structure, integrating the original two devices into one device, with a more compact structure, smaller footprint, and greatly reduced costs; moreover, the products screened by the optical screening assembly can be directly dropped into the back-seal packaging assembly for automatic packaging, without any other additional transfer steps in between, so the operation is more convenient and the work efficiency is higher.

[0063] In addition, the screening and packaging integrated machine also includes a feeding assembly 4, which includes a vibration plate 41 and a feeding track 42. The vibration plate 41 can be directly set on the working platform or on an independent cabinet 43. The cabinet 43 is placed on the side of the machine base, which is more convenient for manual feeding. The feeding track 42 is tilted, one end of which is connected to the vibration plate 41 and the other end extends to the turntable 21. The above-mentioned feeding assembly 4 can realize automatic sorting and feeding of products, and can place products one by one at the edge of the turntable 21 to ensure the stable operation of the screening assembly.

[0064] It also includes a finished product discharging conveyor belt 5, which is arranged corresponding to the material receiving assembly 34. After packaging is completed, the finished product is directly delivered by the finished product discharging conveyor belt 5, which further improves work efficiency.
