Description

Technical Field

[0001] The invention relates to the technical field of circuit board production, and in particular to a circuit board cutting device. Background Art

[0002] With the rapid development of modern science and technology, electronic products have become popular in thousands of households. Driven by the market economy, people's requirements for electronic products are getting higher and higher, and electronic products have been constantly updated. Electronic products widely used in the market all achieve their corresponding electronic functions by installing functional devices on the circuit substrate and using a stable power supply.

[0003] Miniaturized and integrated electronic products are the mainstream in the current market. In the development process of electronic products, the circuit substrate is the main body of the electronic product. Even experienced engineers find it difficult to design it in one go, and the product needs to be debugged and optimized. In addition, the miniaturized design makes the debugging position of the substrate less and less, and redesign and optimization will affect the development cycle of the product. Therefore, existing debugging methods such as "flying wire" (interconnecting two pads with wires), adding devices, cutting off circuits, etc., all require cutting and modifying the circuit of the substrate.

[0004] The invention patent with Chinese patent number CN108943098A discloses a convenient cutting position adjustment device for electronic product production, which is roughly described as: comprising a base, the top outer wall of the base is connected to a collection box by bolts, and the top of the outer wall of one side of the collection box is welded with two symmetrically arranged connecting frames, and the outer walls of the two opposite sides of the two connecting frames are welded with the same rotating shaft. When the existing convenient cutting position adjustment device for electronic product production is used, the position of the circuit board is adjusted by the first roller, the second roller, the second slide rail and the third slide rail, and then the circuit board is cut by the cutting machine.

[0005] When the existing electronic product production is used to adjust the cutting position, it is found that when adjusting the position of the circuit board, it can only change the position of the circuit board in a large range, and cannot accurately adjust the cutting position of the circuit board, which reduces the cutting accuracy of the circuit board. In addition, the movement of the circuit board is lateral movement, and the cutting board cannot be turned, which makes it inconvenient to cut the corners of the circuit board to achieve the purpose of reducing the area of ​​the circuit board. Therefore, we provide a circuit board cutting device. Summary of the invention
