A film feeding device for automotive glass

Abstract

The invention discloses a film feeding device for automobile glass, and mainly relates to the technical field of glass processing. Including a conveyor belt, the outer surface of the conveyor belt is provided with a plurality of limiting grooves, the bottom of the limiting groove is provided with a first air hole through which the conveyor belt passes, and the outer circumference of the limiting groove is surrounded by a circle of second air holes through which the conveyor belt is obliquely penetrated. , there is a buffer air box between the upper and lower layers of the conveyor belt. The opening of the buffer air box is located at the top, and the opening of the buffer air box can cover the limit groove and the second air hole. An inflatable airbag is fixed, and the top surface of the inflatable airbag abuts against the bottom surface of the upper conveyor belt after being inflated, and the buffer air box and the inflatable airbag are respectively connected to an external air source. The beneficial effect of the invention is that it adjusts the position of the film relative to the conveyor belt, thereby greatly improving the accuracy of the position of the film and the position of the bottom glass.

Description

technical field [0001] The invention relates to the technical field of automobile glass processing, in particular to a film feeding device for automobile glass. Background technique [0002] Automobile glass is indispensable in the accessories of automobile body, and mainly plays a protective role. There are three main types of automotive glass: laminated glass, tempered glass and area tempered glass, which can withstand strong impact. Automobile glass is divided into four types according to its location: front windshield, side window glass, rear windshield glass and sunroof glass. The front windshield is laminated glass (the national mandatory standard must be implemented!), the side window glass is tempered glass, and the rear windshield is generally tempered glass with electric heating wire. [0003] The advantage of laminated glass is that there will be no flying debris after the glass is hit. Since the interlayer has glue links, even if the glass is broken, it will st...

Problems solved by technology

[0006] The grabbing, lifting, rotating, and blanking of the mechanical arm is a grabbing transfer process with guaranteed accuracy, and the position correspondence can be guaranteed during the transfer. However, since half of the existing film conveyor belts use belt conveyors, through the conveyor belt In transportation, the film is thin and large, and it is easy to have a slight shift in the position during the bumps of transportation, so that the film cannot be accurately located at its proper position. Even if the transfer accuracy of the mechanical arm is high, the correspondence accuracy between the film and the glass will also increase. If you don't go up, it will have a direct adverse effect on the quality of the subsequent film
