Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.
[0023] For the measurement of the surface accuracy of the mobile phone case, since optical three-dimensional measurement requires diffuse reflection on the measurement surface and the mobile phone case is too smooth and bright, diffuse reflection is not easy to occur, so it is necessary to use this device to press the film to the surface of the mobile phone case.

Abstract
The invention belongs to the technical field of mechanical engineering, and discloses a mobile phone outer shell diffuse reflection film body covering device including three parts of a shearing unit, a covering object motion unit and a covered part motion unit. The shearing unit is mainly responsible for polytetrafluoroethylene thin film shearing and covering functions and is controlled to move by a press machine; the covering object motion unit is responsible for transmission of a polytetrafluoroethylene thin film; the covered part motion unit includes a boss and a caterpillar band, is responsible for transport of a measured object and also has a positioning function. Based on a structure light three-dimensional measurement technology, the polytetrafluoroethylene thin film characteristics are used for condition support. According to the mobile phone outer shell diffuse reflection film body covering device, the precision measurement of the surface of a mobile phone and other objects is performed in the process of industrial production, the surface of the mobile phone is covered with a layer of polytetrafluoroethylene thin film which can achieve diffuse reflection, so that the precision measurement of the surface is achieved by using the three-dimensional optical measurement technology, the detection efficiency of a mobile phone outer shell is effectively improved, and the rate of finished products is improved.
Description
technical field [0001] The invention belongs to the technical field of mechanical engineering, and more specifically relates to a diffuse reflection film covering device for a mobile phone casing. Background technique [0002] The so-called optical three-dimensional technology is to realize the transformation from two-dimensional graphics to three-dimensional images, and reconstruct three-dimensional objects with two-dimensional projection images. This method uses optical methods to obtain the spatial coordinates of each point on the surface of a three-dimensional object. It is an advanced measurement technology that integrates optoelectronics, computer image and signal processing and other disciplines on the basis of modern optics. It uses optical images as a way or carrier to identify and transmit information, and finally obtains valuable signals from the measured images, and realizes the reproduction of the shape of three-dimensional objects through a computer. Three-dim...
