Then, the pin A-6 is also transferred into the box body 101 by an external mechanical arm and is located between the two groups of first clamping members 206. The pin A-6 is hollow. Then, by controlling the contraction of the output end of the first double-headed cylinder 205, the pin A-6 is also clamped and fixed, and the electric door on the top of the box body 101 is closed. S2. Under the action of the processing mechanism 3, a first hole A-1 is opened at both ends of the front side of the watch case, and a first thread A-2 is opened in the first hole A-1. Then, a second hole A-3 is opened at both ends of the rear side of the watch case, and then a third hole A-4 is opened in the second hole A-3, and then a second thread A-5 is opened in the third hole A-4. It is worth noting that the bottom height of the fixed pin A-6 is compatible with the top height of the first drill bit and the first tapping head. Therefore, the first tapping head can be used to open the third thread A-7 at the end of the pin A-6. The drilling and tapping processes of the watch case and the pin A-6 are carried out in the sealed box 101, so that the generated debris will be collected in the box 101, meeting the needs of the staff; S3. The drilled and tapped watch case is removed from the box 101 by an external robotic arm and placed on the connecting frame 401. By controlling the extension of the output end of the seventh electric push rod 402, the pressure plate 403 is driven to move downward, thereby fixing the watch case on the top of the connecting frame 401. S4. The watch strap to be installed on the right side of the watch case is placed horizontally on the top of the second processing table 103 through the external robotic arm. The output end of the eighth electric push rod 502 is extended, so that the first pressure plate 503 moves downward and fixes the watch strap. Then, the output end of the ninth electric push rod 505 is extended, so that the second pressure plate 506 also moves downward to contact the mounting portion of the watch strap but does not press it tightly, so as to facilitate the subsequent first air needle 511 to enter the mounting portion of the watch strap. Then, with the cooperation of the output end of the first cylinder 508 and the output end of the second cylinder 510, the first air needle 511 finds the gap in the mounting portion of the watch strap and enters the mounting portion of the watch strap. The output end of the ninth electric push rod 505 is reset, and the second pressure plate 506 no longer contacts the mounting portion of the watch strap. The external air pump injects air into the first air needle 511 and sprays it out, so as to "blow up" the mounting portion of the watch strap without wrinkles. S5. The tapped pin A-6 is transferred out through an external robotic arm, and the rear end of the pin A-6 is sleeved on the two sets of second clamping members 517 that fit together. By controlling the extension of the two output ends of the second double-headed cylinder 516, the two sets of second clamping members 517 are driven to move away from each other, thereby clamping and fixing the pin A-6. Afterwards, the output end of the third cylinder 513 cooperates with the output end of the third cylinder 513 to deliver the pin A-6 to the mounting portion of the watchband. At this time, the front end of the pin A-6 is aligned with the front side of the mounting portion of the watchband. Then, the first air needle 511 is reset, and the output end of the third cylinder 513 is extended, so that the pin A-6 and the entire watchband move to the left. S6. Use two sets of third clamping members 608 to secure the pin A-6, which is located inside the strap mounting portion. The output of the second stepper motor 604 and the output of the fifth cylinder 606 work together to move the pin A-6 and the strap synchronously. At this point, the pin A-6 is located inside the right ear plate of the watch case, and the center of the pin A-6 is aligned with the center of the first hole A-1. S7. Under the action of the output end of the third stepper motor 704, the two groups of fitted fourth clamping members 708 move to the center position of the pin A-6, and under the cooperation of the sixth cylinder 706 and the fourth double-headed cylinder 707, the two groups of fourth clamping members 708 enter the front side of the pin A-6 and fix the pin A-6. Then, under the cooperation of the output end of the sixth cylinder 706 and the output end of the third drive motor 709, the pin A-6 rotates and moves forward, thereby achieving the installation of the pin A-6 in the first hole A-1 on the right side of the watch case. Then, under the action of the output end of the third stepper motor 704, the second air needle 714 moves to the center position of the pin A-6. Under the action of the extension of the output end of the seventh cylinder 713, the second air needle 714 enters the interior of the pin A-6 and also blows air, thereby achieving the "blowing up" of the mounting part of the watch strap again without wrinkles. S8. Under the action of the fourth mounting mechanism 8, the magnetic head 808 is in a vertical state, and the bolt A-8 at the discharge end of the vibrator 803 is sucked, and then the magnetic head 808 is adjusted to a horizontal state. Then, with the cooperation of the output end of the ninth cylinder 806 and the output end of the fifth drive motor 810, the magnetic head 808 is pushed forward while rotating, and the bolt A-8 is installed in the third hole A-4. The nut of the bolt A-8 is hidden in the second hole A-3 and does not protrude, thereby ensuring the aesthetics of the mechanical watch. The front end of the bolt A-8 extends to the rear side of the pin A-6, so that the strap mounting part is sleeved on the pin A-6 and the bolt A-8, thereby realizing the installation of the right strap. S9. Turn the watch case over through the external mechanical wall. At this time, the ear plate originally located on the left side of the watch case will face the right side. Repeat the above operation to install another strap of the mechanical watch here. The whole process is automated, meeting the needs of the staff and is convenient and fast.
