Problems solved by technology

However, this test method can only roughly observe the texture, which has a large error, and the placed car film will affect the inaccuracy of the texture on the projection due to unevenness
On the other hand, relying on human eyes to judge the texture quality of car film not only has the risk of subjective error, but also causes discrimination errors due to visual fatigue caused by long-term labor of the human eye, which is not conducive to precise control of the texture quality of functional films

Abstract

The invention provides a functional film line tester and a testing method for a functional film. The tester comprises a light source device, a clamping device, light guiding components and a display device. The light source device is used for emitting testing light rays. The clamping device comprises a sealing shell and a clamping press frame connected to the sealing shell in an openable mode, the sealing shell is provided with a sealing cavity and a sealing opening enabling the sealing cavity to be communicated with the outside, the clamping press frame is provided with a press frame opening, a clamping part is suitable for pressing the functional film to the part between the sealing opening and the press frame opening so that the sealing cavity can be in a sealed state, and the functional film is flatly laid and spread by regulating the air pressure of the sealing cavity. The light guiding components are arranged on the front side and the rear side of the clamping part and used for guiding the testing light rays to the clamping part. The display device is used for carrying out imaging processing and analyzing on a projection image guided out by the light guiding components. Thus, the line quality of the functional film of an automobile can be easily and accurately controlled, and errors are reduced.

Description

technical field [0001] The invention relates to a test device, in particular to a tester suitable for testing the texture of an automobile film and a test method thereof. Background technique [0002] As a protective material, functional film is widely used in various fields, among which the most widely used is in the automotive field, which is commonly known as car film. Car film is to paste a layer of film-like objects on the front and rear windshields, side windows and skylights of the vehicle, and this layer of film-like objects is also called solar film or explosion-proof heat insulation film. The main function of the car's functional film is to block ultraviolet rays, block some heat, and prevent injuries caused by sudden glass bursts. At the same time, according to the one-way perspective performance of the solar film, it can achieve the purpose of protecting personal privacy. In addition, the functional film can also reduce the damage caused by ultraviolet radiation...
