[0016] Among them, the first positioning component 1 and the second positioning component 2 are arranged on the upper end surface of the mounting base 3, the first positioning component 1 includes a plurality of first positioning columns 11 arranged along the left-right direction, and the second positioning component 2 includes a plurality of second positioning columns 21. When the ceramic base is placed on the mounting base 3, its two adjacent right-angled sides are respectively attached to the first positioning component 1 and the second positioning component 2, and the right angles corresponding to the two adjacent right-angled sides are the fixed angle A. The sides of the ceramic base where the fixed angle A is located are the first side and the second side, respectively, and the angles formed by the other two adjacent right-angled sides are the dynamic angle B. The sides of the ceramic base where the dynamic angle B is located are the third side and the fourth side, respectively; the correction locking component 4 is arranged on the outside of the dynamic angle B, and includes a third clamping portion 43 that always has a tendency to move toward the third side at least when the ceramic base is fixed, and a fourth clamping portion 44 that always has a tendency to move toward the fourth side.

[0018] The correction locking assembly 4 includes a mounting block 41 mounted on the side of the mounting base, a third spring 432 that enables the third clamping rod to always have a tendency to move toward the third side, and a fourth spring 442 that enables the fourth clamping rod to always have a tendency to move toward the fourth side, the third spring is connected between the proximal end of the third clamping rod and the mounting block, and the fourth spring is connected between the proximal end of the fourth clamping rod and the mounting block.

[0019] The correction locking assembly includes an unlocking cylinder 45, which is mounted on the mounting block and is used to drive the distal ends of the third clamping rod and the fourth clamping rod to move away from the ceramic base.

[0020] In order to make the positioning device suitable for different types of ceramic bases, the mounting base also includes a detachable suction cup 0 arranged on its upper end surface, and an exhaust hole 07 is opened on the suction cup 0 (the suction cup 0 is a prior art and is not described here), and the suction cup has a first side surface 01, a second side surface 02, a third side surface 03 and a fourth side surface 04 which are respectively parallel to and one-to-one correspond to the first side surface, the second side surface, the third side surface and the fourth side surface, and a first positioning groove 011 and a second positioning groove 021 matching the first positioning column 11 and the second positioning column 21 are respectively opened on the first side surface and the second side surface, and the first positioning groove 011 and the second positioning groove 021 are respectively opened on the mounting base 3 The projection on it is U-shaped; a third positioning groove 031 and a fourth positioning groove 041 corresponding to the third clamping column 433 and the fourth clamping column 443 are respectively provided on the third side 03 and the fourth side 04, the width of the third positioning groove 031 is greater than the diameter of the third clamping column 433, and the width of the fourth positioning groove 041 is greater than the diameter of the fourth clamping column 443.
