Description

Technical Field

[0001] The utility model relates to the technical field of circuit board drilling, in particular to a circuit board drilling device with a depth adjustment function. Background Art

[0002] Circuit boards, also known as printed circuit boards, can miniaturize and visualize circuits, and play a very important role in electrical appliances that fix circuits. In the production process of circuit boards, it is usually necessary to drill holes at set positions on the circuit boards to facilitate the installation of the circuit boards or the spot welding connection of the circuits. Existing circuit board drilling devices mostly use robotic arms, which are programmed in advance to set the position movement distance, direction, and drilling depth of each drill hole one by one. When the drilling depths of the circuit boards are different, the drilling depth setting program of the robotic arm needs to be adjusted again, which reduces production efficiency and is difficult to solve by an external depth adjustment structure. In addition, during the drilling process, the circuit boards will be worn out, and debris and other debris will splash out. When the debris accumulates on the table where the circuit boards are placed, it will affect the base height of the circuit boards, thereby affecting the drilling depth and causing the drilling depth to fail to reach the set depth.
