Then, since the bearing seat 3 and the XYθ guide member 2 are also quickly installed or positioned through the second assembly part 26, the occurrence of the bearing seat 3 and the described XYθ guide member 2 can also be avoided. The deviation between the XYθ guide members 2 can ensure the accuracy of the present invention during assembly, so as to reduce the need for re-calibration after assembly, thereby improving the efficiency of assembly.

When there is an error in the coordinate origin and coordinate angle of the work area, the controller will automatically compare and calculate the coordinate compensation error value to output the compensation The parameters are sent to the X-direction driving assembly 23 or the Y-direction driving assembly 24 to return the bearing seat 3 to the center coordinates.
