The assembly process of the unit curtain wall 100 is as follows: the glass 120 is covered on the upper surface of the curtain wall frame 110, a gap is provided between the lower surface of the glass 120 and the upper surface of the curtain wall frame 110, a structural adhesive 130 is injected into the gap between the glass 120 and the curtain wall frame 110, the glass 120 is adhered and fixed to the curtain wall frame 110 by the structural adhesive 130, and then the edge guard 140 is installed on the side wall of the curtain wall frame 110 and the glass 120, and then the filler (foam rod) 150 is installed between the edge guard 140 and the side wall of the glass 120, and finally the edge guard 140 and the glass 120 are sealed by the sealant 160, and the assembly and production of the unit curtain wall 100 is completed.

[0080] At present, during the assembly and production of the unit curtain wall 100, the assembly process of the glass 120, the application process of the structural adhesive 130, the application process of the sealant 160, and the inspection process after the unit curtain wall 100 is assembled are all completed manually by the operator, with low automation and production efficiency. The assembly quality of each process of the unit curtain wall is also difficult to control and cannot meet the modern production needs. Therefore, the industry needs to design a set of automatic assembly production line system for unit curtain walls to realize the intelligent assembly of unit curtain walls. After the edge guard and filler are installed, how to automatically inject sealant into the gap between the glass and the edge guard is a problem faced by technical personnel in the industry.

[0081] In order to solve the above problems, the inventor of the present application proposed the technical solution of the present application, and the specific embodiments are as follows:
