[0002] Currently, commonly used circuit board depaneling machines mainly include milling cutter type depaneling machines and hobbing cutter type depaneling machines. Milling cutter type depaneling machines can be applied to the processing of various types of circuit boards and have a wide range of applications.

[0003] According to utility model patent application CN209970834U, published on January 21, 2020, a circuit board separating machine is disclosed. The separating machine includes a frame and a feeding device, a transfer device, a conveying device, a cutting device, and a discharging device, all mounted on the frame. The feeding device transports the circuit board to be processed, and the transfer device transports the circuit board to the conveying device. The conveying device is located on one side of the feeding device and transports the circuit board to the cutting device for positioning. The cutting device includes a set of roller cutters located on the side of the conveying device away from the feeding device and cutting the circuit board along the length of the feeding device. The discharging device is located on the side of the cutting device away from the feeding device to output the processed circuit board. Its main technical advantage is that it achieves fully automated cutting, improving production efficiency.

[0004] Existing PCB depaneling machines only have two stations during cutting, and both stations simultaneously handle feeding and discharging. This results in only one station being used for processing at a time, leading to low processing efficiency. To address this, a multi-station rotary cutting machine and PCB processing method are proposed, aiming to solve the technical problem of low processing efficiency caused by only one station being used for processing in existing PCB depaneling machines. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-station rotary cutting machine and a circuit board processing method, which aims to solve the technical problem that existing PCB depaneling machines can only perform processing at one station, resulting in low processing efficiency.

Then, the diameter of the milling cutter is detected by the second detection probe 251. After it is detected that it needs to be replaced, the first lifting motion mechanism 512 drives the cutting milling cutter assembly 513 to reset. Then, the rotation drive mechanism 21 drives the rotary table 22 to rotate. When the rotary table 22 rotates, the carrier 3 rotates at the same time, which drives the waste collection bucket 26 to rotate.

Subsequently, the rotary drive mechanism 21 drives the rotary table 22 to keep rotating, and drives multiple carriers 3 on the rotary table 22 to rotate simultaneously, so that the carriers 3 located at the first station 4, the second station 5, the third station 6, and the fourth station 7 rotate in sequence. When the carrier 3 moves to the second station 5, the circuit board is cut by the upper cutting mechanism 51 or the lower cutting mechanism 52. When the carrier 3 moves to the third station 6, the circuit board is cut or inspected by the upper cutting mechanism 51 or the set detection mechanism. When the carrier 3 moves to the fourth station 7, the circuit board is moved from the carrier 3 to the unloading mechanism 12 by the moving robot 71.
