Background technique

Mobile phone battery covers are generally divided into two types: snap-on type and push-pull type. In the testing department of a mobile phone manufacturer, it is generally necessary to conduct a plug-in life test on the battery cover of the mobile phone to test the life and feel of the battery cover. Among them, for the push-pull battery cover, it is generally necessary to test the pull-out force before and after the plug-in life test, that is, the force required for the battery cover to leave the battery case connected to it, so as to determine the pull-out force. The variation value is not within the standard range. At present, the pull-out force of the push-pull battery cover is mainly measured directly by using a tension gauge. The specific method is: stick a sticky plate on the outer surface of the battery cover, and then one person fixes the mobile phone shell, and the other uses the pull force The pulling hook of the gauge hooks the sticky board, and the pulling force can be read from the tension gauge. However, this method has at least the following two disadvantages: one is that two people are required to measure the pull-out force, resulting in increased labor costs; the other is that this method is difficult to ensure that the tension meter and the pasting board are on the same height and straight line , the accuracy of the pull-out force measured in this way is low and the error is high, which leads to unreliable test results.

In addition, in the prior art, the change of the hand feel of the battery cover is entirely dependent on manual subjective judgment: before the test, the inspector first subjectively feels the hand feel of the battery cover (the pulling force required to open the battery cover), and then conducts 500 times on the battery cover. -3000 times of disassembly and assembly experiments, and then the inspectors subjectively feel the feel of the battery cover (the pulling force required to open the battery cover). Since the subjective judgments of each inspector may be inconsistent, they lack professionalism. This leads to inaccurate judgments.

In view of this, the present invention aims to provide a device for testing the pull-out force of a mobile phone push-pull battery cover and a test method for the feel of the battery cover, which solves the problem of the pull-out force test of the mobile phone battery cover.
