[0002] In order to meet market needs, some products need to be packaged in packaging boxes after they are manufactured, which can not only improve the grade of the products but also protect the products. Common packaging boxes usually include a box body, an upper cover and upper side ears connected to the upper end of the box body, and a lower cover and lower side ears connected to the lower end of the box body.

[0003] When packing the product in a box, you need to first fold the two lower side ears at the lower end of the box body inward, then fold the front tongue of the lower cover into the bottom of the box body, and after completing the assembly of the lower cover, put the product in from the upper end of the box body, then fold the two upper side ears inward, and finally fold the front tongue of the upper cover into the top of the box body to complete the packaging.

[0004] However, currently, when products are packaged in packaging boxes, they are usually packaged and processed step by step by manual labor. This packaging method has a low degree of automation and low work efficiency. It is not only time-consuming and labor-intensive, but also has very low production capacity. The assembly efficiency often cannot meet the needs of the factory. In addition, manual assembly is also prone to damaging the packaging box, resulting in the production of defective products.
