The utility model has the beneficial effects that:

1. the device contains balancing weight and laminating bubble cotton for replace cell-phone module laminating cover plate glass to drop test (the complete machine falls, the cylinder falls the test such as), because the cotton low price of bubble, and balancing weight reuse, greatly reduce test cost.

2. The device is because balancing weight and the cotton quality of laminating bubble are even, can effectively reduce the problem that test module rocked or overturned when glass cover plate falls the test, improves data stability.

3. The device carries out the test of glass falling performance of the cover plate, can accomplish to test at once after the assembly, improves efficiency of software testing.

4. The device carries out glass cover plate drop performance test, because glass cover plate has one side adhesion laminating bubble cotton, effectively reduces glass broken back sputtering problem, improves the test security.

To sum up, thereby the device replaces the cost of cell-phone reduction test through setting up the balancing weight and the cotton combination of laminating bubble, can avoid appearing rocking and upset in the test procedure simultaneously to the device is through the cotton laminating glass of laminating bubble, can avoid the broken back of glass to sputter.
