Description

Technical Field

[0001] The invention belongs to the technical field of process equipment, and in particular relates to a bonding device and method in a process of bonding a rain erosion head and a radar cover body. Background Art

[0002] The rain erosion head is installed at the front end of the radome and is installed with the radome body by gluing. In order to ensure the quality of the rain erosion head bonding, a special tool is required for positioning and installation. The tool must first be able to position the radome body, then evenly apply the bonding glue to the rain erosion head installation hole, and finally install the rain erosion head and apply constant pressure to the rain erosion head for the required time to ensure a firm bond.

[0003] During the bonding process, the installation process of the cover must be safe and fast, and no bumps or collisions should occur. The adhesive should be applied evenly and in an appropriate amount. The pressurization process of the rain erosion head is safe and controllable. During the bonding process, excess adhesive should not flow into the cover and stain it.

[0004] The traditional bonding tool is a closed structure, and the space for installing the cover is very limited. The cover is easy to collide with the tool during installation. The operator is very careful and slow in the process of installing and positioning the cover to ensure safety, but the efficiency is low. Because the tool is a closed structure, the operator cannot directly observe the coating quality of the glue in the installation hole during the gluing process, which affects the bonding quality between the rain erosion head and the cover.
