[0031] Working principle:

[0032] Electronic products are transported via a feeding assembly 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 diameter of the second gear is larger than that of 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, giving the electronic products a transition position during movement and preventing them from flying out uncontrollably due to high-speed changes in direction.

[0033] When using the sorting unit for the above-mentioned product processing, automatic sorting of products can be achieved by reversing and diverting the products. When reversing products, the reversing operation can be split into multiple sub-units by multiple synchronously rotating guide seats, ensuring the stability of the product reversing process. Furthermore, by setting the combination of rotation angles of the guide seats, the stability of the products during the reversing process can be further improved while realizing the reversing and sorting of products, avoiding the situation of products going out of control due to excessive reversing speed, and improving the accuracy of sorting.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
