With the rapid development of smart phones, customers have higher and higher requirements for the overall strength of mobile phones, and the proportion of screen cracks caused by the drop of mobile phones in the market is also increasing. The steel ball drop test can effectively simulate the glass screen when the mobile phone falls to the ground. Can withstand impact.

In the actual test, it is generally necessary to use steel balls of appropriate weight to drop from different heights for testing, such as using 110g steel balls to drop freely from heights of 20cm, 30cm, 40cm, 50cm, 60cm, and 70cm, and drop them vertically at the center of the test glass , the glass is not broken as qualified. However, in the traditional steel ball drop test process, the test height often needs to be changed. The test process is cumbersome to operate, and during the test process, due to the friction loss between the steel ball and the steel pipe, it is easy to cause inaccurate test results, and it may also cause damage to the product when the product breaks. Testers cause injuries and cause safety incidents.
