Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a welding workstation for front and rear windshields of automobiles. Background Technology

[0002] The front and rear windshield frames of a car refer to the frame structures installed around the front and rear windshields of a car. Their main function is to fix and protect the glass, while also providing a certain degree of safety and aesthetics. The front and rear windshield frames are used to fix and protect the glass: the windshield frames firmly fix the glass to the car body with adhesive or other fixing methods to prevent the glass from loosening or falling off during driving. They can also protect the glass from direct impacts and damage from the external environment to a certain extent.

[0003] Referring to patent publication number "CN108788594A", a fixing device for welding the rear bumper of an automobile is disclosed, which includes a base and a welding platform on the base.
