Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, and in particular relates to a flexible opening device for circuit boards. Background Technology

[0002] Circuit boards are the supporting platform for electronic components and circuits. They connect various electronic components together through conductive lines to realize the transmission and control of electrical signals. In the process of circuit board manufacturing, hole drilling is one of the key processing steps, which directly affects the installation of subsequent components and the stability of circuit connections. Hole drilling devices are used when drilling holes in circuit boards.

[0003] A utility model patent application with publication number CN220693408U discloses a flexible drilling device for circuit boards, including a clamping assembly. The clamping assembly includes an operating table, a first mounting hole, a first clamping motor, a first forward and reverse screw, a first clamping block, a first limiting groove, a first clamping arm, a positioning frame, and a first limiting hole. Two first clamping arms and two second clamping arms can move simultaneously inward or outward, facilitating the clamping and fixing of circuit boards of different sizes. Clamping the circuit board from four sides simultaneously provides a more secure fixation, thereby improving the drilling accuracy. Positioning is achieved by activating the first servo motor and the electric telescopic arm to move the drill bit on the drilling motor back and forth and left and right, thus facilitating multi-position positioning and drilling of the circuit board clamped at the center of the positioning frame.

[0004] Although the above technical solution achieves a firm fixation of the circuit board by clamping it from four sides with two first clamping arms and two second clamping arms, when the circuit board is clamped and directly attached to the surface of the operating table, the drill bit is prone to contact with the operating table after penetrating the circuit board, resulting in drill bit wear or damage to the surface of the operating table, which affects the service life of the equipment. If a certain distance is maintained between the circuit board and the operating table to avoid damage to the operating table by the drill bit, the bottom of the circuit board at the drilling point lacks support during the drilling process. The downward pressure applied by the drill bit may cause the circuit board to bend locally or even break. In addition, the above technical solution does not have any debris collection mechanism. The debris generated by drilling is easy to adhere to the thread structure, affecting its use.

[0005] To address these issues, we provide a flexible perforation device for circuit boards. Utility Model Content
