Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically a six-axis CNC drilling machine for circuit board manufacturing. Background Technology

[0002] A printed circuit board (PCB) is a crucial component in electronic devices used to carry and connect electronic components, often referred to as the "skeleton" of electronic products. It uses pre-designed conductive patterns (copper foil traces) to achieve electrical connections between electronic components (such as chips, resistors, and capacitors) while providing mechanical support. PCB manufacturing refers to the entire process of transforming insulating substrates, conductive materials (mainly copper), and auxiliary materials into a PCB with a specific circuit pattern through a series of precision processing techniques. A PCB drilling machine is a precision automated device specifically designed to process various holes on the PCB; it is a key piece of equipment in the PCB manufacturing process for achieving interlayer electrical connections and component mounting and positioning.

[0003] Traditional drilling equipment is mostly three-axis (X, Y, Z) controlled, which can only process vertical holes in a plane. It is difficult to meet the processing requirements of complex holes such as angled holes, multi-angle holes, and irregular holes in circuit boards (especially multilayer boards and high-density interconnect boards). It cannot meet the installation requirements of high-precision electronic components. In addition, the workpiece clamping mechanism and support structure of traditional equipment are fixed, making it difficult to adapt to circuit boards of different sizes. When changing the processing object, the equipment needs to be adjusted frequently, which is cumbersome and time-consuming, reducing production efficiency. Utility Model Content

[0004] To address the issues of insufficient processing capability for complex holes and poor processing adaptability, the purpose of this utility model is to provide a six-axis CNC drilling machine for circuit board production.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a six-axis CNC drilling machine for circuit board production, comprising a base, a first lead screw rotatably connected to the upper surface of the base and a first support plate slidably connected thereto, a first motor fixedly connected to one side of the base, the output end of the first motor being fixedly connected to one end of the first lead screw, the outer surface of the first lead screw being threadedly sleeved with the lower part of the first support plate, a second support plate slidably connected to the upper surface of the first support plate, a support assembly fixedly installed on the upper surface of the second support plate, a second lead screw rotatably connected to the lower surface of the second support plate, the outer surface of the second lead screw being threadedly sleeved with the lower part of the first support plate, a second support plate slidably connected to the upper surface of the second support plate, a support assembly fixedly installed on the upper surface of the second support plate, and a second lead screw rotatably connected to the lower surface of the second support plate, the outer surface of the second lead screw being threadedly sleeved with the lower part of the first support plate.
