Description

Technical Field

[0001] The utility model relates to the technical field of automobile assembly windshields, in particular to a flexible automatic installation pressure-maintaining device shared by front and rear windshields of an automobile. Background Art

[0002] At present, the flexible automatic installation and pressure-maintaining functions of automobile windshields are mainly realized through manual installation and automatic installation combined with manual pressure-maintaining. Among them, manual installation of windshields obviously no longer meets the current production requirements; automatic installation of windshields combined with manual pressure-maintaining means that the robot carries a vacuum suction cup for installation and then manually maintains the pressure. The existing automatic installation of windshields combined with manual pressure-maintaining has the following two disadvantages:

[0003] 1. After the windshield is automatically installed, it needs to be manually pressed at the next workstation, which increases labor and site costs;

[0004] 2. After the windshield is automatically installed, it cannot be guaranteed that the windshield will be pressed into place.

The windshield position needs to be adjusted manually later, which increases the manual workload and work difficulty.

[0005] In summary, the existing automobile windshield flexible installation and pressure maintenance have the disadvantages of low automation and high installation cost. Utility Model Content
