Hot wind edge covering structure and method for interior top lining skylight

Abstract

The invention relates to the field of automobiles, in particular to a roof lining sunroof hot air wrapping structure and method. Put the product on the bottom fixture, align the position of the car sunroof with the corresponding opening of the sunroof on the wrapping module, and the lower pressure shaft drives the lower pressure structure to press down the car sunroof; then the hot air copper pipe of the heating part is put down and placed in the bag Above the edge module, the hot air comes out through the hole of the hot air copper pipe and blows to the iron sheet of the sunroof. After the set time, the hot air is heated and the hot air copper pipe in the heating part rises; at this time, the edge wrapping module presses the car sunroof position to ensure After pressing, the hemming module returns, and the lower pressing shaft drives the lower pressing structure to rise back to its position. The new process uses hot air copper pipes to transport hot air, which has low heat loss, is easy to handle, saves space, and is easy to maintain. When heating, the hot air copper pipe is relatively far away from the product, and there is no contact, which can completely avoid carbon deposits or product pollution.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a roof lining sunroof hot air wrapping structure and method. Background technique [0002] 1) The currently used hemming machine is a heating rod style hemming machine with a power of about 15Kw and a large power consumption. [0003] 2) Each heating rod corresponds to a series of circuit control elements (SRR, RELAY, etc.), and the wiring in the control box is compact. [0004] 3) The heater is embedded in the heating block, and the product is heated through the heating block, which causes a lot of heat loss and takes up a lot of space. [0005] 4) After the heating block is used for a long time, it is easy to form carbon deposits on the surface and pollute the product. Contents of the invention [0006] Purpose of the invention: In order to provide a roof lining sunroof hot air hemming structure and method with better effect, the specific purpose is shown in the multiple substant...
