Description

Technical Field

[0001] This utility model applies to the technical field of circuit board cutting, and particularly relates to a circuit board cutting device. Background Technology

[0002] Circuit boards are indispensable components in electronic devices, serving as the carriers for electrical connections between electronic components. The manufacturing process of circuit boards typically involves processes such as material preparation, drilling, copper plating, pattern transfer, electroplating, and etching. In the material preparation step, a large sheet of material is usually cut into smaller pieces to meet design requirements. Circuit board cutting is typically done by feeding the material into a cutting machine. A typical cutting machine includes a frame, a cutting blade, and a drive unit. The material is fed onto the frame, and the drive unit then moves the cutting blade to cut the material. However, after a period of use, the cutting blade wears down, becoming less sharp and resulting in poor cutting quality. In this case, the cutting blade needs to be replaced.

[0003] Circuit boards, also known as printed circuit boards or printed circuit boards, are called PCBs and FPCs in English. They are characterized by high wiring density, light weight, thinness, and good bendability. FPCs are also called flexible circuit boards. Flexible circuit boards are printed circuit boards made of polyimide or polyester film as the substrate. They are highly reliable and have excellent flexibility. The birth and development of FPCs and PCBs gave rise to the new product of rigid-flex boards. Therefore, rigid-flex boards are circuit boards that combine flexible circuit boards and rigid circuit boards through processes such as lamination, according to relevant process requirements, to form a circuit board with the characteristics of both FPCs and PCBs.

[0004] In the early stages of circuit board processing, the circuit boards need to be cut into specified dimensions. Current methods involve placing the raw material on a conveyor platform, aligning it, and pushing it forward. The cutting blade then cuts the circuit board. After cutting, finished products and waste materials must be separated and collected. When cutting circuit boards, cutting directly from one side results in a change in the board's width, making clamping the entire board inconvenient. Furthermore, leaving a certain thickness can generate excessive heat during the cutting process, potentially damaging the circuit board's wiring. Most existing cutting equipment can only cut in a single direction. After the cutting equipment cuts the circuit board horizontally, the circuit board needs to be manually rotated 90 degrees so that the cutting equipment can cut vertically, thus completing a crisscross cut. This cutting method is cumbersome, requires a lot of manpower, and makes it difficult to guarantee cutting accuracy. For example, Chinese Patent CN107182169B discloses a circuit board cutting system that controls the cutting depth to prevent excessive heat from burning the circuit board during the cutting process. However, the flipping device needs to flip the circuit board and cut both sides separately. During the flipping process, the circuit board is prone to displacement or falling, thus affecting the cutting accuracy. Therefore, it is necessary to provide a circuit board cutting device that is compact, has high cutting accuracy, does not require a flipping device, and can cut both sides of the circuit board, preventing excessive heat from burning the circuit board during the cutting process. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and to provide a circuit board cutting device with a compact structure, high cutting precision, no need to set up a flipping device, and to realize the cutting of the front and back sides of the circuit board, thereby preventing the circuit board from being burned by a large amount of heat during the cutting process.

[0006] The technical solution adopted by this utility model is as follows: This utility model includes a conveyor line, with the length of the conveyor line as the X-axis and the width of the conveyor line as the Y-axis. An upper cutting module and a lower cutting module are respectively arranged above and below the conveyor line. Both the upper cutting module and the lower cutting module include XY-axis linear modules. The moving end of the XY-axis linear module is provided with a lifting module. The moving end of the lifting module is provided with several sets of drive motors arranged in parallel. The moving end of the drive motor is provided with a micro motor. The moving end of the micro motor is provided with a cutting wheel blade.

[0007] As can be seen from the above scheme, the XY-axis linear module drives the lifting module to move in the X-axis direction or the Y-axis direction. The lifting module drives the drive motor to move in the Z-axis direction. The drive motor drives the micro motor to move in the R-axis direction. The micro motor drives the cutting wheel to rotate. The cutting wheel cuts the circuit board of the conveyor line. The upper cutting module and the lower cutting module cut the top and bottom of the circuit board respectively, realizing the cutting of the front and back sides of the circuit board. This avoids the displacement of the secondary cutting position during the flipping process of the circuit board, eliminating the need for a flipping device and ensuring high cutting accuracy of the circuit board. Through alternating cutting...

A stop module is provided on one side of the conveyor line 1 to stop the circuit board. The upper cutting module 2 starts working first, while the lower cutting module 3 is in standby mode. The XY axis linear module 4 drives the lifting module 5 to move in the X-axis or Y-axis direction. The lifting module 5 drives the drive motor 6 to move in the Z-axis direction. The micro motor 7 drives the cutting wheel 8 to rotate, and the cutting wheel 8 cuts the circuit board. The drive motor drives the micro motor to move in the R-axis direction, achieving a crisscross cut on the circuit board.
