Parallelism detecting device and film sticking machine

Abstract

The invention provides a parallelism detecting device. The parallelism detecting device comprises a TOF distance measuring instrument, a reflector and a first driving mechanism, wherein the TOF distance measuring instrument and the reflector are respectively arranged at the two sides of a substrate; the first driving mechanism can drive the TOF distance measuring instrument and the reflector to move along the lateral edge parallel to the substrate; the relative position of the TOF distance measuring instrument and the reflector is unchanged; and the light pulse emitted by the TOF distance measuring instrument can be received by the TOF distance measuring instrument after being reflected by the substrate, a film layer and the reflector. The invention also provides a film sticking machine. The film sticking machine comprises the parallelism detecting device mentioned in the above technical scheme and can adjust the angle of the film layer or/and the angle of the substrate. According to the parallelism detecting device provided by the invention, when moving, the TOF distance measuring instrument emits the light pulse repeatedly, the light pulse is received by the TOF distance measuring instrument after being reflected by the film layer, the substrate and the reflector, and multiple travel time is obtained; and whether the substrate and the film layer are parallel is judged by comparing the travel time. The film sticking machine provided by the invention can adjust the parallelism between the film layer and the substrate.

Description

technical field [0001] The invention belongs to the technical field of film sticking, and more specifically relates to a parallelism detection device and a film sticking machine. Background technique [0002] With the development of society, people's requirements for products are getting higher and higher. Some substrates (such as household glass, TV glass, decorative glass, etc.) often need to be coated with a layer of film to protect, block, To decorate or increase the effect of perspective. [0003] Take a TV glass as an example. In the prior art, it is difficult to keep parallel between the film layer and the TV glass when the film layer is pasted on the TV glass. In this way, the film layer is not only skewed in appearance, but also unsightly, which affects the TV glass. The overall effect, and even affect the use of TV glass. [0004] In the actual application of the film layer, because the parallelism between the TV glass and the film layer is difficult to detect, i...
