Description

Technical Field

[0001] The invention relates to the technical field of luggage assembly, in particular to an automatic assembly machine for axle buckles of luggage wheels. Background Art

[0002] Luggage is a general term for bags, and is a general term for various bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, satchels, waist bags and various trolley cases, etc. Some bags are equipped with wheels at one end. When installing the wheels in these bags, the wheels and wheel axle buckles need to be assembled, which is generally installed manually.

[0003] At present, during installation, the wheels of the luggage are installed on the axle, and then the buckle sleeve is set on the axle. When assembling the buckle, the buckle parts at both ends are installed on the wheel by manual hammering. This assembly efficiency is low and the labor intensity of workers is high. At the same time, due to manual hammering, the assembly position of the buckle is prone to deviation, which affects the flexibility of wheel rotation and produces defective products.

[0004] For example, a shaft buckle automatic assembly machine for luggage wheels disclosed in the Chinese invention patent publication number CN219190078U includes luggage, wheels, axles, buckles, buckle fixings, a fixing seat, a power oil cylinder and an assembly machine. The buckle sleeve is arranged on the axle, the wheel is placed on a fixing seat, the luggage is placed on the table of the assembly machine, the power oil cylinder is connected to a fixing seat, the buckle fixing is arranged on a fixing seat, and the buckle fixing is connected to the piston rod of the power oil cylinder, and the power oil cylinder can drive the buckle fixing to press the buckle on the wheel. The shaft buckle automatic assembly machine for luggage wheels of the utility model can replace manual labor, can be used for semi-automatic assembly of buckles on axles, improve production efficiency, and can determine the assembly position of the buckle through the buckle fixing, thereby ensuring that the assembly position of the buckle will not deviate and ensuring the assembly quality. At the same time, the buckle can be assembled corresponding to axles of different lengths by replacing the positioning device.

[0005] However, the above device does not effectively fix the luggage during the wheel installation and assembly of the luggage, so that the luggage is stably placed on the assembly machine for wheel assembly. This may cause one end of the luggage wheel axle buckle to deviate or tilt during assembly and installation, thereby affecting the assembly accuracy and efficiency.

[0060] In this embodiment, the horizontal plate 604 drives the connecting seat 614 to move when it moves. When the roller 621 contacts the outer surface of the luggage body 4, the roller 621 rotates until the roller 621 on the other side of the upper surface of the isosceles right-angle plate 619 contacts the outer surface of the luggage body 4 and rotates, driving the isosceles right-angle plate 619 to rotate. The isosceles right-angle plate 619 then stretches the connecting spring 623. The isosceles right-angle plates 619 on the four sides move simultaneously to position the luggage body 4 in the middle position of the upper surface of the placement plate 302 for assembly of the shaft buckle 402.
