[0018] Example 2: A sorting device for product processing includes: a feeding conveying assembly 1, a discharging conveying assembly 2, and a sorting table 3 connected between the feeding conveying assembly 1 and the discharging conveying assembly 2. At least one barcode scanning unit 41 is provided above the feeding conveying assembly 1. Each barcode scanning unit 41 is provided with a detection unit 42 near the outside of the sorting table 3 and above the feeding conveying assembly 1. The left and right sides of the sorting table 3, which is connected to the feeding conveying assembly 1 and the discharging conveying assembly 2 at the front and rear ends respectively, are respectively connected with a first guide groove 51 and a second guide groove 52. The upper surface of the sorting table 3 is provided with a plurality of mounting through holes 6 arranged at equal intervals along the feeding direction and in a direction perpendicular to the feeding direction. A guide seat 7 is rotatably installed in each mounting through hole 6. A plurality of synchronously rotating guide wheels 8 are rotatably installed on the upper part of each guide seat 7. The upper part of the outer circumference of the guide wheel 8 is flush with or slightly higher than the upper surface of the sorting table 3. A plurality of guide seats 7 are arranged at equal intervals in at least four rows along the feeding direction. At least two rows of guide seats 7 located in the middle are each equipped with a first gear 91 at their bottom, and two rows of guide seats 7 located on the outer sides are each equipped with a second gear 92 at their bottom. Multiple first gears 91 located in the same row mesh with a left-right extending first rack 11, and multiple second gears 92 located in the same row mesh with a left-right extending second rack 12. The first rack 11 and the second rack 12 are each connected to a drive rod 10. The drive rod 10, which can move along the length direction of the first rack 11 and the second rack 12, is connected to a pneumatic push rod 13 fixedly installed at the bottom of the sorting table 3. The outer diameter of the first gear 91 is smaller than the outer diameter of the second gear 92. At least two first racks 11 are located on the same side of at least two rows of first gears 91, and two second racks 12 are located on both sides of two rows of second gears 92.

[0019] The ratio of the outer diameter of the first gear 91 to the outer diameter of the second gear 92 is 1:2.

[0020] When the first gear 91 is at the 0° position, the rotation direction of the guide wheel 8 on the guide seat 7 is the same as the feeding direction.

[0021] The aforementioned scanning unit 41 and detection unit 42 are each equipped with two units. Electronic products with normal detection results are sent out from the discharge conveyor assembly 3 for subsequent processing. Detection assembly 1 5 and detection assembly 2 7 are infrared detection assemblies. When the middle of the two assemblies is blocked by an electronic product, it indicates that a product has passed by. At this time, the scanning component above performs scanning detection. If the number of detections by the detection component and the number of scans by the scanning component do not match, it indicates that there are missed scans. The probability of missed scans is reduced by the cooperation of the two sets of detection components and scanning components.

[0022] Working principle: After testing, electronic products are transported via a feeding conveyor assembly, where they are scanned and then moved to a sorting table for sorting. The sorting table has guide troughs on both sides, and a pneumatic push rod drives a rack to rotate a guide seat. The first rack and the second rack can drive the guide seat to rotate by driving the first gear and the second gear, respectively. The second gear has a larger diameter than the first gear. When the first rack drives the first gear to rotate 90°, the second gear will only rotate 45°. This allows the outer guide seat to rotate at a smaller angle, providing a transition position for the electronic products during movement and preventing them from flying out uncontrollably due to high-speed changes in direction.

[0023] When using the above-mentioned product processing sorting device, it can automatically sort products by reversing and diverting them according to the detection results. When reversing products, it can also split the reversing operation into multiple sub-units by multiple synchronously rotating guide seats, ensuring the stability of the product reversing process. Furthermore, by combining the rotation angles of the guide seats, it can further improve the stability of the products during the reversing process while realizing product reversing and sorting, avoiding the situation of products going out of control due to excessive reversing speed, and improving the accuracy of sorting. The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
