The first vertical driving source 25 drives the suction cup 21 and the product to be inspected to move vertically upward to move away from the third material tray 13. The flipping driving source 23 drives the suction cup 21 and the product to be inspected to flip 180° until the product to be inspected is located above the suction cup 21 and the back of the product to be inspected faces upward. The visual inspection component 30 then takes a picture of the back of the product to be inspected. After taking the picture, the flipping component 20 puts the product to be inspected on the suction cup 21 back to its original position on the third material tray 13.

[0030] In some possible embodiments, reference Figure 3 As shown, the identification and transfer component 40 includes a second movable seat 42, a code reader 43 and a material transfer robot 44, wherein the second movable seat 42 is connected to the output end of the second three-axis linkage module 41, the code reader 43 and the material transfer robot 44 are arranged on two opposite sides of the second movable seat 42, and the second three-axis linkage module 41 can drive the second movable seat 42 to move in the horizontal lateral and horizontal longitudinal directions, and drive the code reader 43 and the material transfer robot 44 to move in the vertical direction respectively; the code reader 43 is connected to an external processing and control component, the code reader 43 can read the identification code on the product and send the read information to the external processing and control component, and the material transfer robot 44 is used to transfer the NG products on the third material tray 13 to the second material tray 12, and transfer the OK products on the first material tray 11 to the third material tray 13 for filling.

[0031] In some possible embodiments, reference Figure 3 and Figure 4As shown, the second three-axis linkage module 41 includes two second vertical driving sources 411 respectively arranged on opposite sides of the second moving seat 42, and the two second vertical driving sources 411 respectively drive the code reader 43 and the material moving robot 44 to move along the vertical straight line. Specifically, the material moving robot 44 includes a first fixed plate 441 and a second fixed plate 442 which are arranged at an upper and lower interval at the output end of the second vertical driving source 411. The second fixed plate 442 is provided with a plurality of suction members 443 arranged horizontally and facing vertically downward. A first elastic member 444 is provided between the suction member 443 and the second fixed plate 442. The first elastic member 444 enables the suction member 443 to always have a tendency to move vertically upward. The first fixed plate 441 is provided with a plurality of suction members 443 which are arranged horizontally and vertically downward. The driving rod 445 corresponding to the part 443 is used to drive the corresponding suction part 443 to move vertically downward so that the lower end of the suction part 443 is close to the product, which is convenient for the suction part 443 to suck or place the product; it can be seen that the material transfer robot 44 of the present application can transfer multiple products at a time, that is, each suction part 443 can be driven by the driving rod 445 to protrude from the lower end, so that the product can be sucked or placed individually. Such a structural design can reduce the number of times the material transfer robot 44 returns when transferring materials, thereby improving production efficiency; in this embodiment, the driving rod 445 can be the output end of a linear cylinder, and the driving rod 445 is driven by air pressure to move vertically up and down to crimp the pressing sheet 4432 or cancel its crimping force on the pressing sheet 4432.

[0032] In some possible embodiments, reference Figure 4 As shown, the suction member 443 includes at least two suction rods 4431 arranged at intervals along the horizontal longitudinal direction, and a pressing plate 4432 is provided at the upper end of the suction rod 4431. The output end of the driving rod 445 abuts against the pressing plate 4432 and drives all the suction rods 4431 to move vertically downward synchronously through the pressing plate 4432. The suction member 443 of this embodiment is suitable for the situation where the product is in the shape of strips or sheets. In this case, multiple suction rods 4431 are required to simultaneously absorb several positions of the strip-shaped or sheet-shaped product.

The second elastic member 4434 enables the second suction nozzle 4433 to always have a tendency to move vertically downward, so as to provide a certain buffer between the second suction nozzle 4433 and the product, thereby preventing the second suction nozzle 4433 from directly impacting the product and causing damage to the product surface or even crushing the product.

[0034] In some possible embodiments, reference Figure 5As shown, the visual inspection component 30 includes a mounting base 32 and a linear array camera 33 and two photographing light sources 34 respectively arranged on the mounting base 32. The linear array camera 33 is located above the photographing light source 34. The two photographing light sources 34 are spaced apart so that a through hole 35 is reserved between the two for the linear array camera 33 to take pictures. The first three-axis linkage module 31 drives the visual inspection component 30 to move above the third material tray 13. The two photographing light sources 34 are turned on and aimed at the product to be inspected on the third material tray 13 so that the linear array camera 33 can focus on the product and take a picture of the product. Furthermore, a plurality of cooling fans 36 are also arranged on the outside of the photographing light source 34 to ensure that the photographing light source 34 can be well cooled and the service life of the photographing light source 34 is extended.

[0035] It should be noted that the first three-axis linkage module 31, the second three-axis linkage module 41, the first vertical drive source 25, the second vertical drive source 411, the horizontal longitudinal drive source 26 and the flip drive source 23 of all the above-mentioned embodiments can adopt conventional and mature designs and models in the industry, and the present application does not make improvements to the above-mentioned drive elements, so the specific structure and implementation principle of the above-mentioned drive elements will not be repeated here.

[0036] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
