Calibration device and calibration method for assembly included angle of XY-axis linear module

The invention relates to a calibration device and a calibration method for an assembly included angle of an XY-axis linear module. The device comprises a computer, an X-axis linear module, a Y-axis linear module, an objective table, a light source assembly, an image acquisition module and a calibration plate, wherein the image acquisition module is used for being electrically connected with the image acquisition module, the objective table is used for placing the calibration plate, and the X-axis linear module and the Y-axis linear module are both arranged on the objective table; the device also includes a support, the light source assembly and the image acquisition module are positioned above the objective table and are both mounted on the support. By adoption of the calibration device and the calibration method, the problems that in the prior art, time and labor are wasted, labor intensity is high and efficiency is low when manual detection is conducted are solved, and the requirements for high efficiency a
