Specifically, a matching groove Q abutting against the inner plug spraying channel s2 is formed on the positioning seat 2, wherein the matching groove Q is located at the upper part of the positioning seat 20.

In this example, the matching groove Q includes a center hole Q1 provided in the center of the positioning socket 20, and a communication groove Q2 communicating with the outside from one side of the center hole Q1, wherein the hole diameter of the center hole Q1 is larger than the outer diameter of the first channel S21 and the hole depth is also larger than the length of the first channel S21, the depth of the communication groove Q2 is 2 times the thickness of the second channel S22, when the position calibration of the inside plug S is completed, the lower end of the first channel S21 is inserted into the center hole Q1, and the second channel S22 is inserted into the communication groove Q2.

In this example, there are two positioning seats 20, and the bottom is rotatably connected to the calibration platform 1 through bearings 22.

In this example, the robot 40 includes a robot arm 400 movable in an X, Y, Z axis coordinate system, and a pickup head 401 provided on the robot arm 400. In the robotic field, it is clear that the robotic arm 400 is implemented to move in a three-dimensional coordinate system, which is also commercially available in conventional technology and will not be described in detail herein.

Meanwhile, the material taking sleeve a comprises a sleeve body a1 and a polishing ring a2 arranged on the inner wall of the sleeve body a1, and when material is taken, the inner wall of the polishing ring a2 is in matched butt joint with the outer wall of the inner plug. In this embodiment, in the process that the inner plug and the positioning seat 20 rotate synchronously to the initial position of the positioning seat, the excess parts (many corner burrs and the like) or the bonding objects on the surface of the inner plug can be ground, so as to be beneficial to matching with the wall surface of the outer cover.

In this example, the polishing ring a2 includes an annular polishing ring body a20 matching with the annular side surface of the inner plug S, and a polishing sheet a21 matching with the top surface of the inner plug S, wherein the polishing sheet a21 contacts with the top surface of the inner plug S in a full face contact manner, and the height of the annular polishing ring body a20 is greater than that of the inner plug S, so that the optimal polishing effect can be achieved.
