Description

Technical Field

[0001] The invention relates to the technical field of circuit board production, in particular to a plate groove milling device used for printed circuit board production. Background Art

[0002] Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can be called printed circuit boards or printed circuit boards. The birth and development of FPC circuit boards and rigid-flex boards-FPC and PCB have given rise to a new product, the rigid-flex board. Therefore, the rigid-flex board is a flexible circuit board and a rigid circuit board, which are combined together through lamination and other processes according to relevant process requirements to form a circuit board with FPC characteristics and PCB characteristics.

[0003] The insulation effect between the strong current and weak current of the PCB is achieved only by the PCB material, but the withstand voltage is limited. The withstand voltage of the PCB is not low, but it will be contaminated by dust over time. The creepage distance is the phenomenon that the insulation resistance is reduced due to contamination and moisture on the surface of the insulator, and current is generated (or arcs are generated even under high voltage). After the PCB is slotted, short-distance direct air insulation is used to ensure the electrical clearance and withstand voltage to a certain extent.

[0004] According to the patent website's announcement of "A plate milling device for printed circuit board production (publication number: CN217344421 U; application number: 202221240872.1)", the above application targets: "In the production of printed circuit boards, the plates need to be laminated, and some printed circuit board products use electromagnetic bonding to rivet the boards during the lamination process, resulting in abnormalities at the rivets, delamination and breakage during subsequent processing, hiding the potion, affecting the adhesion of the dry film of the outer circuit process, and causing an increase in the scrap rate" and "In the existing production of printed circuit boards, the plates need to be laminated, and the potion used in the lamination work is easily hidden between the multi-layer circuit boards, which causes the later circuit boards to be delaminated. At the same time, the circuit boards are slotted to cause the potion to flow out, and the slotting is mostly carried out with the cooperation of a robotic arm, which not only has a huge production cost, but also a slow manufacturing speed." The problem has been optimized, but the position of the 'limiting gas rod 6' in the above application is fixed and cannot be adjusted. The above device can only fix and process circuit boards of a single size when in use, and cannot process circuit boards of different models, and has low applicability. At the same time, when the device in the above application is used to groove the circuit board, the debris generated between the 'groove milling wheel 405' and the circuit board will splash in all directions as the 'groove milling wheel 405' rotates, causing the ground near the device to be filled with debris formed after the circuit board is processed, which is inconvenient for the staff to clean up. At the same time, there is no corresponding structure to protect the mechanical energy of the 'groove milling wheel 405', which will cause the staff's hands to come into direct contact with the 'groove milling wheel 405' when operating again, which can easily cause damage to the staff's hands and has low safety.
