[0035] Those skilled in the art can understand that, by driving the second gear 606 to rotate through the output end of the transmission motor 608, the outer teeth 603, the rotating circle 601 and the inner teeth 602 rotate as a whole, so that all the first gears 604 rotate synchronously, driving all the racks 607 to move synchronously toward or away from the center position of the fixed circle, thereby causing all the clamping members 605 to move synchronously toward or away from the center position of the fixed circle.

[0036] The working principle and use process of this device: In order to clearly describe the working principle of the present invention, we use Figure 1 To illustrate the perspective, the specific steps are as follows: S1. The manipulator 101 and the suction cup cooperate to suck the middle portion of the top of the external circuit board and transfer it to the first suction cup 202 on the lower side. The first suction cup 202 sucks the middle portion of the bottom of the circuit board. Then, the output end of the second electric push rod 204 extends, driving the upper first suction cup 202 to approach the lower first suction cup 202 to clamp the circuit board. The upper first suction cup 202 also sucks the middle portion of the top of the circuit board. S2. Determine whether the half holes are to be drilled on the long sides or short sides of the current circuit board according to the requirements for drilling half holes on the circuit board. Under the action of the output end of the second drive motor 205, the first driven wheel 207 and the second electric push rod 204 rotate as a whole, thereby driving the clamped circuit board to rotate so that the side of the circuit board to be drilled faces the half-hole drilling mechanism 3. S3. Under the cooperation of the output end of the first stepper motor 304 and the output end of the second stepper motor 308, the bottom tube 310 moves to the bottom of the circuit board. It is worth noting that the top of the outer surface of the bottom tube 310 is cut off in half, and the side of the circuit board to be opened just abuts against the outer wall of the notch of the bottom tube 310. The outer diameter of the top tube 316 is equal to the inner diameter of the bottom tube 310. Driven by the output end of the third stepper motor 315, the top tube 316 moves downward and fits with the top of the circuit board. The top tube 316, the bottom tube 310 and the milling head 106 are in a concentric state. The center of the milling head 106 and the edge of the circuit board are located on the same vertical straight line. Then, under the cooperation of the output end of the third electric push rod 317 and the output end of the fourth drive motor 319, the milling head 106 moves downward and rotates to achieve drilling a half hole in the circuit board. S4. During the half-hole drilling process, the "waste" generated cannot splash out from the bottom tube 310 and the top tube 316. Under the action of gravity, it will fall into the bottom tube 310 for collection. It is worth noting that some "waste" will still be scattered on the top of the circuit board. At this time, the output end of the first drive motor 103 drives the rotating member 104 to rotate, so that the clamped circuit board, the bottom tube 310 and the top tube 316 are in an overall tilted state, so that the "waste" scattered on the top of the circuit board will also fall into the bottom tube 310. When the "waste" in the bottom tube 310 is full, the staff can disassemble the bottom tube 310 and pour out the "waste". In this way, the generated "waste" is easily collected and the work surface is avoided from being messy. S5. After the punching is completed, the manipulator 101 and the suction cup cooperate to transfer the circuit board to the second clamping mechanism 4 for clamping and fixing. Under the action of the output end of the fifth drive motor 405, the second driven wheel 407 and the fourth electric push rod 404 rotate as a whole, driving the clamped circuit board to rotate so that the side of the circuit board with the half hole is facing the electroplating mechanism 5. Secondly, the output end of the first electric push rod 111 is extended so that the cathode 112 contacts the circuit board. S6. Under the cooperation of the output end of the fourth stepper motor 504, the output end of the fifth stepper motor 508, and the output end of the fifth electric push rod 512, the corresponding tube 109 moves to fit with the top of the circuit board, the inner wall edge of the corresponding tube 109 coincides with the edge of the half hole, and the center of the corresponding tube 109 and the center of the half hole are located on the same vertical line. The sixth electric push rod 515 is started, driving the liquid spray head 520 and the air jet head 521 to move downward as a whole to the middle and lower part of the corresponding tube 109. Under the action of the output end of the seventh drive motor 516, the liquid spray head 520 rotates and is opened at the same time, spraying the electroplating solution onto the inner wall of the corresponding tube 109. The cover plate 514 contacts the top of the corresponding tube 109, preventing the electroplating solution from flying out of the top of the corresponding tube 109. In addition, the sprayed electroplating solution enters the inner wall of the half hole under the action of gravity, thereby achieving copper electroplating on the inner wall of the half hole of the circuit board. S7. In real life, the half holes on the circuit board are arranged on the side. After the electroplating of one half hole is completed, the other half hole needs to be electroplated immediately. At this time, the electroplating liquid has not completely flowed out from the bottom of the corresponding tube 109. In order to prevent the electroplating liquid from flowing out from the bottom of the corresponding tube 109 and contaminating the surface of the circuit board when the position of the corresponding tube 109 is adjusted, the present invention also provides a corresponding nozzle 521. The nozzle 521 is used to spray air. The nozzle 521 is also under the action of the output end of the sixth electric push rod 515, so that the electroplating liquid on the inner wall of the corresponding tube 109 flows out quickly. With this arrangement, copper is only electroplated on the inner wall of the half hole of the circuit board, meeting the needs of the staff; S8. Since the sizes of the half holes to be opened during the production of circuit boards are different, the present invention sets a fixing mechanism 6 in the first disk 320, and drives the connecting frame 312 to rotate through the output end of the third drive motor 311, so that the top tube 316 faces the vertical plate 105, and with the cooperation of the output end of the third stepper motor 315 and the output end of the third electric push rod 317, the 'old' milling head 106 is put back into the hole opened in the vertical plate 105, and under the action of the output end of the second stepper motor 308, the first disk 320 is moved to the top of the 'new' milling head 106, and with the cooperation of the output end of the third stepper motor 315 and the output end of the third electric push rod 317, the first disk 320 moves downward, so that the top of the 'new' milling head 106 enters the interior of the first disk 320 and is clamped by the fixing mechanism 6, so that the milling head 106 can be quickly replaced according to production needs. At the same time, after the milling head 106 is replaced, the size of the half hole is changed, so the corresponding tube 109 needs to be adaptively replaced. In order to make the inner wall edge of the corresponding tube 109 coincide with the edge of the half hole, a fixing mechanism 6 is also provided in the second disk 522, so that the design of the present invention is more rigorous, and the operation is fully automated without the participation of staff, which improves the practicality and applicability of the device and has substantial improvements in real life.
