Description

Technical Field

[0001] The utility model relates to the field of circuit board processing, in particular to an automatic replacement device for a micro-hole drilling die. Background Art

[0002] A circuit board is also called a circuit board. It is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use a circuit board to make electrical connections between the various components. The circuit board consists of an insulating base plate, connecting wires, and pads for assembling and welding electronic components. It has the dual functions of a conductive line and an insulating base plate.

[0003] Circuit boards often need to be drilled during the production process. Among them, micro-hole drilling is mostly done by laser drilling due to factors such as accuracy, efficiency, and quality. When the laser drilling device is started to process micro-holes, the laser will first pass through the hole drilling mold, and then contact and ablate with the surface of the circuit board to form a hole. The hole drilling mold can further improve the positioning accuracy during drilling, and can control the size of the hole to ensure that the diameter and shape of each hole meet the requirements. However, when the circuit board needs to be drilled on both sides, and the hole type and hole position of the double-sided processing are inconsistent, the hole drilling mold needs to be replaced. The existing laser micro-hole drilling equipment can only manually replace the hole drilling mold, which is not only inefficient, but also prone to safety accidents. Utility Model Content

[0023] The fixing assembly 20 provided with the lateral adjustment rail 21 and the longitudinal adjustment rail 22 can freely move the fixed circuit board vertically and horizontally, so that the laser drilling assembly 50 can be positioned at any point on the surface of the circuit board for drilling. The fixing clamp 24 axially connected to the fixing frame 23 can turn the circuit board over at any time, so as to realize the double-sided drilling of the circuit board.

[0024] The fixing clamp 24 includes a bearing bottom frame 241 and two groups of upper clamps 242.
