A sealant coating device suitable for the back door of the trunk

Abstract

The invention discloses a sealant coating device applicable to a trunk back door. The sealant coating device comprises a glue outlet pipe. The glue outlet pipe comprises a connecting segment with the rear end capable of being connected with a sealant conveying device and a thin inserting segment connected to the front end of the connecting segment. The front end of the inserting segment is connected with a coating pipe, wherein an included angle is formed between the inserting segment and the coating pipe. A rectangular glue outlet arranged in the axial direction is formed in the side wall of the coating pipe. An adjustable limiting mechanism is arranged on the glue outlet pipe. The adjustable limiting mechanism comprises a sliding ring sleeve arranged on the inserting segment in a sleeving manner. A limiting rod is arranged on the side wall of the sliding ring sleeve. A locking screw capable of locking the sliding ring sleeve is arranged on the sliding ring sleeve. According to the sealant coating device applicable to the trunk back door, continuous coating of sealant of the truck back door can be achieved, so that the production efficiency can be improved, the sealing rust resistance of the truck back door is guaranteed, the requirement on the technical proficiency of operating personnel can be lowered, and meanwhile the consistency of the sealant profile is guaranteed.

Description

technical field [0001] The invention relates to a sealant coating device for automobile manufacturing, in particular to a sealant coating device suitable for the connection between the folded edge of the outer panel and the inner panel of the trunk back door. Background technique [0002] The back door on the trunk of a car includes a back door outer panel and a back door inner panel. The periphery of the back door outer panel has a folded edge bent inward, and the back door inner panel and the folded edge of the back door outer panel are welded together . The outer side of the back door is anti-rust through a surface coating such as paint. In order to improve the anti-rust performance of the back door, it is usually necessary to use a sealant coating device to connect the inner panel of the back door with the outer panel of the back door. Apply a layer of plastic sealant to the back door, which can effectively prevent rainwater from entering the inside of the back door, an...
