Abstract
Provided is a coplanarity-testing machine. The coplanarity-testing machine includes a working stage, an illuminant, an image picking-up processor, a frequency converter, a double-cross lines generator, a linear module and a display. The linear module includes a test vehicle, a linear drive mechanism and a regulating block. The linear drive mechanism can drive the test vehicle to linearly move to and fro on a bearing surface of the working stage. The regulating block is placed on a supporting surface of the test vehicle. By adjusting the double-cross lines generator, horizontal lines of the generator can coincide with a projecting line of the bottom surface of the regulating block, and vertical lines of the generator can measure the height of the regulating block. The coplanarity-testing machine can timely and exactly display the testing result, is easily operated, and has a high testing efficiency and a high exact degree of testing.
