Description

Technical Field

[0001] The utility model relates to the technical field of PCB board production, in particular to a cutting device for PCB board production. Background Art

[0002] In today's electronics industry, printed circuit boards (PCBs) play an indispensable and crucial role as the electrical connections for electronic components. Like the "skeleton" and "blood vessels" of electronic products, they support various electronic components and ensure stable and efficient signal transmission between them. From everyday smartphones and computers to precision instruments and large-scale communications equipment used in industrial production, virtually all electronic devices rely on PCBs. Cutting devices used in PCB production are highly utilized, placing increasingly stringent demands on their precision and efficiency.

[0003] Existing cutting devices for PCB production generally use a loading assembly. The loading and unloading processes take a long time, causing the cutting mechanism to be in a waiting state for a long time, which greatly reduces production efficiency. In addition, the existing cutting devices have poor protection. During the cutting process, debris splashes, posing a threat to the operator's safety. If the debris enters the equipment, it will also affect the normal operation of the equipment. Furthermore, when clamping the PCB board, the existing cutting device may cause the PCB board to be subjected to significant impact and deformation. During the cutting process, the lack of a shock-absorbing mechanism will transmit vibration to the PCB board, affecting the cutting accuracy. Utility Model Content

[0036] The working principle of the present invention is as follows: when the cutting device cuts the PCB board, the alternating transmission component 41 is first started to drive the first loading component 42 to move outside the cutting box 2, and the PCB board is placed between the two sets of clamping components 44 for clamping and fixing. Then, the alternating transmission component 41 is started again to drive the first loading component 42 to move into the cutting box 2. The cutting box 2, the protective door 21 and the first loading plate 421 form a closed space to prevent debris from splashing during cutting. When the first loading component 42 is moved into the cutting box 2, the alternating transmission component 41 also drives the second loading component 43 to move out of the cutting box 2. During the process of cutting the PCB board on the first loading component 42, the next PCB board can be clamped and fixed to the second loading component 43. After the previous PCB board is cut, the next PCB board can be directly transported to the cutting box 2. The first loading assembly 42 is sent to the cutting box 2, which reduces the time for unloading and reloading of one loading assembly, thereby effectively improving work efficiency. After the cutting of the previous PCB board is completed, the alternating transmission assembly 41 is started again to drive the first loading assembly 42 to move out, and the second loading assembly 43 moves into the cutting box 2. Then, the third electric telescopic rod 432 is started to drive the second loading plate 433 to rise, forming a closed space with the cutting box 2 and the protective door 21, and then the cutting work is carried out. This reciprocating cycle works; when the first loading assembly 42 moves in and out of the cutting box 2, the protective door 21 is pushed up and down by the convex plate 5, ensuring that the PCB board is always in a closed state during the cutting process, and the debris generated during the cutting will not splash at will, thereby achieving a better protection effect. The debris generated during the cutting will fall into the collection box 61 through the chip discharge hole 45 for recycling.
