[0014] In the present invention, the principle of patch position adjustment is as follows: first fix the PCB on the mounting station 3. When fixing, use the first positioning bar 12 as the reference line, and align the mounting position and the positioning point 31. Then, according to the mounting position of the chip, fix the position of the fixing frame 2 and one of the positioning grooves 32, so as to position and fix the position of the mounting position in the X-axis direction. Finally, adjust the position of the support plate 14 in the Y-axis direction through the driving member a, adjust the position of the fixing block 16 in the Z-axis direction through the driving member b, and rotate the probe 18 to a suitable angle, and the probe adjusts the position of the chip.
