Detection device for mobile phone shells

Abstract

The invention provides a detection device for mobile phone shells, including a bottom plate, a first installation component which is arranged above and connected with the bottom plate and is providedwith a first installation slot, a positioning component which is arranged in the first installation slot to support a mobile phone shell, a second installation component which is arranged to the sideof the first installation component and connected with the bottom plate and is provided with at least one second installation slot, and instruments which are arranged in the second installation slotsto detect the size parameters of the mobile phone shell, wherein the second installation component and the bottom plate are of an integrated structure. According to the technical scheme provided by the invention, the mobile phone shell is positioned by the positioning component; the measuring ends of the instruments are in contact with the mobile phone shell so that the mobile phone shell can be conveniently measured; the deviation of the inner length and width and the outer profile relative to the reference center line can be quickly and effectively detected; and the production efficiency canbe greatly improved.

Description

technical field [0001] The invention relates to the technical field of mobile phone casing detection, in particular to a detection device for a mobile phone casing. Background technique [0002] At present, the process of mobile phone parts is complicated and there are many features. The 2D drawings are generally set according to the principle of four-sided centering. This requires us to measure the benchmark with reference to the benchmark center for detection. [0003] In the related technology, the general detection method is: when detecting the inner length and width, because the length is long, it is necessary to take multiple points, and then determine the center line according to the value, and then detect whether there is any deviation in each position according to the center line, which takes a long time , the error is large. At the same time, as to whether there is a deviation of the outer contour relative to the center line (whether the outer contour is milled in...

[0003] In the related technology, the general detection method is: when detecting the inner length and width, because the length is long, it is necessary to take multiple points, and then determine the center line according to the value, and then detect whether there is any deviation in each position according to the center line, which takes a long time , large error

At the same time, for the deviation of the outer contour relative to the center line (whether the outer contour is milled in place), it is necessary to convert the datum many times, and it is even impossible to detect
