Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB board processing technology, specifically to a PCB board drilling device. Background Technology
[0002] In today's era of rapid development in electronic information technology, printed circuit boards (PCBs), as core components of various electronic devices, are widely used in numerous fields such as communications, computers, consumer electronics, and aerospace. As electronic products evolve towards miniaturization, multifunctionality, and high-density integration, higher demands are placed on the design precision and manufacturing quality of PCBs.
[0003] The prior art discloses a PCB board drilling device with announcement number CN211221035U, including a base. The upper end of the base has a first groove, and a first ball screw is installed inside the first groove. A support column is fixedly installed at one end of the first ball screw seat. A fixing block for fixing the PCB board is rotatably connected to the upper end of the support column. A column is fixedly welded to the upper end of the base. The column is configured as a column with a concave cross-section, and a second ball screw is installed inside the column. A support plate is fixedly installed at the upper end of the column, and a first drive motor for driving the second ball screw is fixedly installed at the upper end of the support plate.
[0004] This invention requires only one clamping operation when machining the positioning hole.
[0005] The aforementioned PCB drilling device rotates the fixing block 180° manually and with an angle measuring device, enabling the machining of two sets of centrally symmetrical positioning holes in a single clamping operation. This improves processing efficiency and ensures the central symmetry of the two sets of positioning holes. However, the aforementioned PCB drilling device uses a plate-pushing clamping method to fix the board before drilling. During the clamping process, the position of the PCB board is easily shifted, affecting the drilling accuracy. Therefore, the device is not effective in use and needs to be improved.
