[0055] As Figure 7 shown, the recording device operates on the product recording as follows:

[0056] S1. First, place the products on the conveyor belt 2 in sequence and between two adjacent partitions 20, and use the conveyor belt 2 for conveying;

[0057] S2. An appearance storage card is arranged inside the product appearance recognition camera 30, and the product appearance recognition camera 30 recognizes the appearance of the product;

[0058] S3. After the appearance of the product is recognized in S2, if it does not meet the appearance requirements recorded in the appearance storage card, the signal is transmitted to the infrared sensor 36, and the infrared sensor 36 is used to recognize the product. After recognition, the conveyor belt 2 stops working;

[0059] S4. For the product in the operation of S3, use the third electric rod 17 to push the second limiting plate 22 to move to limit the two sides of the product, and then use the fifth electric rod 33 to push the second pushing plate 32 to move. Use the second pushing plate 32 to push the product onto the second diversion plate 23 for discharge, and the conveyor belt continues to work;

[0060] S5. After the first step of processing the product in S4, use the product size recognition camera 31 to record the size of the product and record it using the storage card;

[0061] S6. After recording the product dimensions, the conveyor belt 2 transports the product through the first deflector 10 into the interior of the collection bin 4, and the bottom recognition camera 5 is used to recognize the bottom of the product;

[0062] S7. After the recognition in S6, the product bottom recognition image information is transmitted to the bottom dimension collection and storage card, and is collected using the interior of the product bottom dimension collection and storage card.

[0063] As Figure 8 shown, the image processing method for recording products:

[0064] S1. The quality of the product is recognized in sequence using the product shape recognition camera 30 and the product dimension recognition camera 31;

[0065] S2. For the recognized images, they are transmitted in sequence using the image sensor, the signals of the image sensor are processed using the signal processor, are transported through digital-to-analog conversion to the image processing device for image recognition, and finally are stored inside the corresponding storage card, and the stored pictures are displayed on the display screen.

[0066] Working principle: When in use, first place the product on the conveyor belt 2, between two adjacent partitions 20. The conveyor belt 2 is used to transport the product. During the transportation process, the product shape recognition camera 30 is used to recognize the shape of the product, and the product dimension recognition camera 31 is used to recognize the dimensions of the product. After being recognized by the product shape recognition camera 30, the recognized signal is transmitted to the infrared sensor 36. The infrared sensor 36 is used to control the third electric rod 17. When a product with unqualified shape is recognized, the recognition information is recorded and stored using the shape storage card. The third electric rod 17 is used to push the second limiting plate 22 to move, which can limit the position of the product. The fifth electric rod 33 is used to push the second push plate 32 to move, so that the product is discharged through the second deflector 23;

[0067] Then, for the products with qualified shape, the storage dimension camera 31 is used to recognize the dimensions of the products. After the recognized products are transported through the first deflector 10 into the interior of the collection bin 4, and the bottom recognition camera 5 is used to recognize the bottoms of the products.
