Description

Technical Field

[0001] The utility model relates to the technical field of door and window frame and leaf profile processing, in particular to a door and window frame and leaf glue injection device. Background Art

[0002] Aluminum profile structures have been widely used in various fields due to their excellent airtightness and durability. Aluminum profile structures can be processed into various structural types of devices according to specific needs.

[0003] In actual application scenarios, the frame-type aluminum profile structure has very important and extensive application value. For aluminum profile structures, it is usually necessary to inject colloid into the corners. This action is usually completed manually, that is, a glue gun is manually aimed at the glue injection holes of the door and window frames to inject glue. The door and window frames are usually large, and the operator needs to carry the glue gun and walk around the window to find the glue injection holes in each corner of the window. The labor intensity is high. Because of the fluidity of the colloid, the situation of the colloid filling the cavity cannot be well observed in real time, so manual glue injection often fails to grasp the appropriate amount of glue injection, either causing the colloid to overflow or insufficient glue injection. It is necessary to check one by one after the glue injection is completed, and at the same time, the glue is supplemented or the excess glue is wiped off. Due to the problem of low work efficiency in manual glue injection, the patent application document with announcement number CN113499950A provides an automatic glue injection device for aluminum profile structure and its working method, and the automatic glue injection device is set to replace the manual glue injection.

[0004] However, before using the glue injection device mentioned in the above patent document to inject glue into the door and window frames, since the glue injection device already knows the injection position in advance, the staff needs to accurately move the door and window frames to the preset injection position. After the injection is completed, they need to manually unload and then move the next door and window frame to be injected. There is a problem of low work efficiency in the process of manual repeated transportation of door and window frames. At the same time, there is a large error when manually adjusting the door and window frames to the preset position, and there is a problem that the quality of glue injection of different door and window frames cannot be guaranteed.
