Of course, the operation of sucking the parts 9 is not limited to be completed before the watch case 2 is placed on the bracket 101. The watch case 2 can also be placed first and then executed, or the parts 9 can be continuously sucked during the assembly process. This is just Describe an example. Then, the positioning device 11 measures the watch case to obtain the initial coordinate information and transmits it to the rotating component 102 . Then, the bracket 101 switches from the Y-axis direction to the X-axis direction in response to the movement of the steering rotary member 1022 of the rotating assembly 102, and the assembly operation of the part 9 can begin. When any part 9 is to be assembled to any peripheral assembly part 20, the A-axis rotating member 1021 of the rotating assembly 102 learns how much displacement the watch case 2 should be rotated based on the initial coordinate information, so that the part to be installed can be The peripheral assembly part 20 of 9 corresponds to the suction object 1212 on which the corresponding part 9 is adsorbed. After the rotation, the first moving component 122 moves the first installation component 121 downward, that is, moves along the Z-axis, so that the suction component 1212 Assemble the component 9 to this peripheral assembly part 20, and then repeat this operation until each peripheral assembly part 20 is equipped with the corresponding component 9.
