Chinese patent application number: 201410036583.3 discloses a glue coating method and device for medical plastic needle filter caps. However, these assembly devices can only complete the assembly of one component, and the degree of assembly automation is not high.

Chinese Patent Application No. 201310505124.0 discloses an automatic assembly process for infusion sets.
