Description

Technical Field

[0001] This invention relates to the field of assembly technology, and in particular to a folding spoon-in-lid assembly machine and its assembly process. Background Technology

[0002] Most eight-treasure porridge sold on the market is packaged in three-piece cans, which consist of a can body and a lid. A three-section folding spoon is assembled inside the lid. The lid and folding spoon are two separate units. The folding spoon is initially extended before being inserted into the lid; the handle must be bent and folded before being pressed into a pre-existing groove in the lid. Currently, in most porridge processing plants in my country, the assembly of the lid and folding spoon during packaging still relies on manual labor or semi-automated equipment. This is not only inefficient and labor-intensive, but also unsuitable for large-scale factory production.

[0003] Existing technical solutions can be referenced from Chinese invention patent CN114799790A, which discloses a three-section spoon-in-lid assembly machine. This invention patent uses a folding spoon assembly with a folding spoon bevel and a folding spoon guard, along with grippers, to fold the three-section folding spoon. However, this invention patent can only fold spoons with an approximately U-shaped bending angle, and there are certain requirements for the bending angle of the folding spoon. Furthermore, this invention patent lacks automatic feeding functionality and cannot sort failed-assembly folding spoons and lids. Additionally, existing technical solutions for automatic lid feeding can be referenced from Chinese invention patent CN110615235A, which discloses a lid-type parts posture adjustment device. This invention patent has difficulty fixing and transporting lids with long, raised protrusions on the back, and the direction of these protrusions is uncontrollable during transport.
