Background

Chinese patent application number CN201821501846.3 a cell phone protective housing, comprising: the mobile phone comprises an upper frame, a lower frame and a back plate, wherein the lower frame is provided with a first face and a second face, the upper frame is connected to the second face of the lower frame to form a cavity for coating the side face of the mobile phone, a flexible layer is arranged on the inner wall of the cavity, the back plate is connected to the first face of the lower frame, a plurality of magnets are arranged on the upper frame and the lower frame, and magnetic poles of the upper frame and the lower frame are combined in a suction mode.

In the prior art, the external dimension of the mobile phone backboard sheet is required to be detected before the mobile phone backboard sheet is sold, and the mobile phone backboard sheet can be sold after the dimension detection is qualified.

In order to improve the detection efficiency of the mobile phone backboard, a mechanical device similar to a secondary measuring instrument is generally used for automatically measuring and recording the external dimension of the mobile phone backboard.

The two-dimensional measuring instrument is called a two-dimensional measuring instrument or an image measuring instrument and a video measuring machine, and is used for measuring the sizes of products and molds. The secondary element measuring instrument (also called image type surveying instrument) is produced based on CCD digital image and by means of computer screen measuring technology and powerful software capability of space geometric operation. After the computer is provided with special control and graph measurement software, the computer becomes a measurement brain with software soul, and is the main body of the whole equipment. The displacement value of the optical ruler can be quickly read, and a required result is obtained instantaneously through software module operation based on space geometry; and a graph is generated on the screen for an operator to carry out image comparison, so that the possible deviation of the measurement result can be intuitively distinguished.

Therefore, when the secondary measuring instrument measures an object, the object to be measured is only required to be placed on the workbench, and the secondary measuring instrument can project the outline of the object to be measured on the workbench, so that data acquisition is carried out on the outer outline of the object to be measured.

However, when the secondary measuring instrument is used for detecting the external dimension of the mobile phone backboard sheet, the thickness of the mobile phone backboard sheet is too thin, so that the mobile phone backboard sheet is extremely flexible, and the dimension under projection is not consistent with the actual dimension when the secondary measuring instrument is used for measuring, and the error on the result is easy to cause.
