Abstract:
1. A coplanarity-testing machine at least comprising a working stage having a horizontal bearing surface, an illuminant, an image picking-up processor, a frequency converter, a double-cross lines generator, and a display, wherein the coplanarity-testing machine further comprising: a linear module, including a test vehicle slidably mounted on the bearing surface of the working stage and having a horizontal supporting surface for carrying at least one test-waiting product; a linear drive mechanism mounted on the bearing surface of the working stage for driving the test vehicle to linearly move to and fro on the bearing surface; and a regulating block corresponding to the test-waiting product, having a horizontal top surface and a horizontal bottom surface, and being placed on the supporting surface of the test vehicle, wherein horizontal lines generated by the double-cross lines generator can coincide with a projecting line of the bottom surface of the regulating block by adjusting the double-cross lines generator, and vertical lines generated by the double-cross lines generator can measure the height of the regulating block, which can be displayed on the display, the test-waiting product illuminated by illuminant can be imaged on the display by the image picking-up processor and the frequency converter.
