Device used for detecting wear resistance performance of mobile phone back-cover

Abstract

The invention discloses a device used for detecting wear resistance performance of a mobile phone back-cover. The device includes a workbench, a mounting bracket, a mobile-phone back-cover fixing device, a testing mechanism and a power mechanism. The mounting bracket is mounted on an upper end surface of the workbench. An upper end of the mounting bracket is provided with a hydraulic cylinder. Themobile-phone back-cover fixing device is arranged at an output end of the hydraulic cylinder. The upper end surface of the workbench is also provided with a base. An upper end surface of the base isprovided with a first sliding rail. The testing mechanism is arranged in the first sliding rail in a moving manner. The power mechanism drives the testing mechanism to reciprocate back and forth in the first sliding rail. The testing mechanism includes a sliding table, a sliding seat, a lead screw, a first motor and a mounting plate. The sliding table is connected with the first sliding rail one in a sliding manner. An upper end surface of the mounting plate is provided with four buffering devices. Upper end surfaces of the four buffering devices are respectively provided with a fingerprint friction block, a sand grain friction block, a cloth friction block and a wooden board friction block. The device used for detecting the wear resistance performance of the mobile phone back-cover can simulate friction on the mobile phone back-cover in a variety of situations, and testing results are accurate and referential.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a device for detecting the wear resistance of the back cover of a mobile phone. Background technique [0002] Before the mobile phone leaves the factory for sale, it is necessary to test whether the performance of the mobile phone is qualified, including a performance test for the wear resistance of the back cover of the mobile phone. The back cover of the mobile phone in the prior art needs to be tested for anti-wear performance during the production process. However, in the prior art, the back cover of the mobile phone is generally tested for anti-wear performance, and the detection efficiency is low. During normal use, there will be friction from different external contact substances. The traditional wear resistance test only uses sandpaper to rub it. The friction with sandpaper is different from the friction that the back cover of the mobile phone receives in daily ...

The back cover of the mobile phone in the prior art needs to be tested for its anti-wear performance during the production process. However, in the prior art, the anti-wear test of the back cover of the mobile phone is generally performed manually, and the detection efficiency is low. Moreover, the back cover of the mobile phone During normal use, it will receive friction from different external contact substances. The traditional abrasion resistance test only uses sandpaper to rub against it. The friction with sandpaper is different from the friction that the back cover of the mobile phone receives in daily life. It is not close to the back cover of the mobile phone. The real friction during daily use makes the test results not referable
