In the medical industry, one-way valves are generally used as control structural components of infusion systems. Infusion one-way valves generally include upper and lower covers that can be snapped together and a rubber pad placed in the snapping space between the upper and lower covers. The upper cover and the lower cover are glued together to form a closed space. There are many ways to assemble one-way valves for infusion, such as a manual assembly mode, but this mode is not only inefficient, but also prone to secondary contamination of the one-way valve. There is also automated assembly, such as the utility model patent with application number 201821172097.4, which discloses an automated assembly machine for one-way valves. Although it realizes the automatic assembly of one-way valves, the assembly efficiency is low and the detection cannot be completed, requiring other equipment for detection. Utility Model Content

The film 12 is a circular sheet, which is loaded through a vibration plate to a linear feeder and then reaches a material picking position. The material picking position is also provided with an in-position sensing device. A suction nozzle is provided on the conveying component. The conveying component has multiple degrees of freedom in multiple directions, including a y-direction conveying module and a z-direction conveying module, which sucks and conveys the film 12 and installs it in the lower cover 11.

[0062] The benefit of adopting the above technical solution is that automatic loading is achieved through the loading method of the vibration plate and the handling assembly. It only needs to place the upper cover 13 and the film 12 in the vibration plate. No manual loading is required.

When the upper cover 13 moves into place under the clamping of the rotating clamp, the dispensing head 61 dispenses glue. During the gluing process, the rotating clamp rotates one circle, and the colloid is evenly spread on the bottom of the upper cover 13. Then the rotating clamp is driven by the conveying component to lower the upper cover 13 and assemble and bond it with the lower cover 11.

[0066] The benefit of adopting the above technical solution is that the setting of the gluing component 6 is used to glue the connection between the bottom of the upper cover 13 and the lower cover 11.

The assembled one-way valve rotates to the curing position, at which time the curing lamp descends for curing, and after curing, it reaches the inspection station for air tightness inspection, and then the unloading device 8 performs classification and unloading of good and bad products to complete the entire processing process. The whole process is automated, and processing and testing are completed without manual participation, with high processing efficiency and good product quality.
