Description

Technical Field

[0001] The invention relates to the technical field of bidirectional V-cutting machines, and in particular to a bidirectional V-cutting machine for a printed circuit board. Background Art

[0002] Bidirectional V-cutting machine is a kind of equipment used for processing metal, plate or other materials, mainly used for cutting or grooving. Specifically, bidirectional V-cutting machine is often used in metal processing, plate processing, wood processing and other fields, especially in the field of precise cutting, grooving or drilling of workpieces. Its name comes from its cutting method - V-shaped cutting path, and its cutting process is bidirectional, which means that it can cut from two directions at the same time or cut alternately in two directions, thereby improving work efficiency.

[0003] According to the disclosed bidirectional V-cutting machine for printed circuit boards (publication number: CN 211090164 U), it includes a conveying base, a first U-shaped frame is fixedly installed in the middle of the upper surface of the conveying base, a second U-shaped frame is fixedly installed at one end of the upper surface of the conveying base, cutting knives are arranged on both inner sides of the first U-shaped frame, first driving motors connected to corresponding positions are fixedly installed on both outer sides of the first U-shaped frame, a second driving motor is fixedly installed in the middle of the upper surface of the second U-shaped frame, a cylinder is fixedly installed at one end of the upper surface of the second U-shaped frame, the output shaft of the second driving motor movably passes through the lower surface of the second U-shaped frame, a threaded column is fixedly welded at the lower end of the output shaft, a threaded sleeve is matched and connected to the outer surface of the threaded column, protruding side plates are fixedly installed on both sides of the threaded sleeve, and a suction cup is movably arranged at the lower end of the threaded sleeve.

[0004] The first U-shaped frame, the first drive motor, the threaded column and other components in the above application cooperate with each other to realize the multi-side cutting function of the circuit board. However, the safety of the operator during the construction of the device in the above application is difficult to ensure. Therefore, we propose a bidirectional V-cutting machine for printed circuit boards. Summary of the invention
