The upper feeding mechanism 2 has an integrated flow channel and an integrated module. The positioning mechanism 3 has a first regularizing component 33. The second detection mechanism 8 has a second regularizing component.

[0041] In operation, the upper feeding mechanism 2 is used to receive products from a previous process and deliver the products to the integrated flow channel, then deliver the products from the upper feeding mechanism 2 to the positioning mechanism 3 through the integrated module, simultaneously regularize all the products through the first regularizing component 33, then turn over the products through the first turnover mechanism 4 and deliver the products to the first detection mechanism 6 through the first robot 5 for primary detection, then deliver the products to the second turnover mechanism 7 after detection, deliver the products to the second detection mechanism 8 through the second robot, regularize the products through the second regularizing component and then perform secondary detection, and finally output the products after secondary detection.

[0042] Specifically, the integration module comprises a first transverse driving member 21, the active end of which is connected with the feeding mechanism 2 to drive the feeding mechanism 2 to move along the transverse direction and deliver the product to the integration flow channel. The first transverse driving member 21 can be a linear module or a screw rod mechanism.

[0043] The feeding mechanism 2 is provided with a first roller assembly 22, which comprises a feeding frame 221, a first rotating member 222 and a rotating rod 223.

Each rotating rod 223 is connected with a pair of material wheels 224. The two material wheels 224 in the same group form an integration flow channel for the product to pass through. In the embodiment, the feeding mechanism 2 has two groups, and each group of the feeding mechanism 2 is provided with two groups of material wheels 224.

The supporting ring 2242 is coaxial with the conveying ring 2241, and the diameter of the conveying ring 2241 is smaller than that of the supporting ring 2242, so that the supporting ring 2242 supports the product. The conveying ring 2241 can slide on the rotating rod 223 to adapt to products of different sizes.

[0045] The feeding frame 221 is provided with a first telescopic member 2211, a first short edge positioning member 2212 and a first long edge positioning member 2213. The first telescopic member 2211 is fixedly connected with the feeding frame 221. The active end of the first telescopic member 2211 is fixedly connected with the first short edge positioning member 2212 and the second short edge positioning member 331.

Two first long edge positioning members 2213 are arranged corresponding to each integration flow channel.

[0046] Specifically, the first long-side positioning member 2213 also has the function of blocking the product. When the product is conveyed to the feeding mechanism 2 from the previous process, the movable end of the first telescopic member 2211 is in the extended state, and at this time the first long-side positioning member 2213 blocks the product. When the product is to enter the feeding mechanism 2, the movable end of the first telescopic member 2211 is in the retracted state, and at this time the product is conveyed to the position above the two first short-side positioning members 2212 by the material wheel 224, and then the movable end of the first telescopic member 2211 is extended to drive the two first short-side positioning members 2212 to move upwards to lift the product, and then the movable end of the first transverse driving member 21 drives the feeding frame 221 to move, so that the integrated flow channel is aligned with the corresponding flow channel of the positioning mechanism 3, and then the movable end of the first telescopic member 2211 is retracted, and the material wheel 224 drives the product to enter the positioning mechanism 3; then the movable end of the first transverse driving member 21 drives the feeding frame 221 to reset, and the movable end of the first telescopic member 2211 is also extended to wait for the next product. The first short-side positioning member 2212 has two guide inclined surfaces 2214 arranged in opposition. The two first short-side positioning members 2212 lift the product, which can reduce the possibility of scratching the product during the movement of the feeding frame 221.

[0049] The movable end of the second driving member 333 is connected with the first clamping member 334 and the second short edge positioning member 331, the movable end of the third driving member 335 is connected with the second clamping member 336, the second driving member 333 is used to drive the second short edge positioning member 331 to move away from or towards the first clamping member 334, so as to make the second short edge positioning member 331 and the first clamping member 334 clamp or release the product in the transverse direction, the third driving member 335 drives the second long edge positioning member 332 to move away from or towards the second clamping member 336, so as to make the second long edge positioning member 332 and the second clamping member 336 clamp or release the product in the longitudinal direction, and the precise positioning and clamping of the product are realized.

[0050] Specifically, the second short edge positioning member 331, the second long edge positioning member 332, the first clamping member 334 and the second clamping member 336 are all provided with four, corresponding to the four flow channels of the second roller assembly 32.

In work, the first robot 5 places the product on the product adsorption table 617 in a horizontal state, then the X-axis moving assembly 611 and the Y-axis moving assembly 612 drive the product adsorption table 617 to a set position, and then the detection assembly detects the product. During the detection process, the first rotary air cylinder 64 can drive the detection lens 62 to swing around the X-axis, the X-axis rotating assembly 614 can drive the product to swing around the X-axis, and the Z-axis rotating assembly 615 can drive the product to rotate around the Z-axis.

[0057] The second turnover mechanism 7 has the same structure as the first turnover mechanism 4, and thus will not be described here. After the product is detected by the detection assembly, the X-axis moving assembly 611 drives the product to move towards the second turnover mechanism 7, then the Y-axis rotating assembly 613 drives the product to rotate 90 degrees towards the second turnover mechanism 7, so that the movable end of the second turnover mechanism 7 adsorbs the product, and then the movable end of the second turnover mechanism 7 rotates 90 degrees, so that the product is in a horizontal state, facilitating the second robot to grasp.

[0058] The second detection mechanism 8 has a third roller assembly 81 and a subsequent detection assembly 82. The third roller assembly 81 has the same structure as the second roller assembly 32 and has two flow channels to store two products at the same time. The first robot 5 places the products on the third roller assembly 81 twice.

[0059] The second shaping assembly 9 includes a second transverse driving member 91 and a shaping clamp 92.

The shaping clamp 92 includes two moving plates 921, each of which is connected with the active end of the second transverse driving member 91. Each moving plate 921 is connected with two limiting bolts 922 to limit the products on the third roller assembly 81 and drive the products to move transversely. The second transverse driving member 91 can be a linear module or a screw mechanism. The transverse direction is the Y-axis direction, and the X-axis direction is the longitudinal direction.

[0060] Working principle: When working, the active end of the first telescopic member 2211 is in the retracted state. At this time, the products are conveyed to the positions above the two first short-side positioning members 2212 by the feed wheel 224. Then the active end of the first telescopic member 2211 is extended to lift the products upward. Then the active end of the first transverse driving member 21 drives the feeding rack 221 to move, so that the integrated flow channel is aligned with the corresponding flow channel of the second roller assembly 32. Then the active end of the first telescopic member 2211 is retracted, and the feed wheel 224 drives the products into the second roller assembly 32.

[0061] After the products enter the second roller assembly 32, the second driving member 333 and the third driving member 335 are started to clamp the products transversely by cooperation of the second short-side positioning member 331 and the first clamping member 334, and to clamp the products longitudinally by cooperation of the second long-side positioning member 332 and the second clamping member 336. Then the first turnover mechanism 4 turns over the products, and the first robot 5 transfers the products to the product detection table 61. After detection by the detection assembly, the products are conveyed to the second turnover mechanism 7. Then the second robot 5 transfers the products to the third roller assembly 81, which are shaped by the second shaping assembly 9 and transferred to the subsequent detection assembly 82.

[0062] A detection process based on the above multi-channel appearance detection equipment includes the following steps:
