Abstract

The invention discloses a 3D printing device and method for repairing faults of a circuit board, and belongs to the field of 3D printing. The 3D printing device and method are used for repairing the circuit board. An industrial camera is mounted above a workbench of a micro-jet 3D printer, a controller is connected with the micro-jet 3D printer, the industrial camera and a four-probe measuring instrument, the four-probe measuring instrument is located above the workbench, and an infrared laser is arranged on a working arm, provided with a printer nozzle, of the micro-jet 3D printer. The controller is used for controlling a spraying path and a spraying amount of the micro-jet 3D printer, and controlling a working path of the infrared laser by controlling a working arm of the micro-jet 3D printer, the industrial camera is used for identifying the fault position of the circuit board, and the four-probe measuring instrument is used for measuring the conductivity of the circuit board. Through organic combination of a 3D printing technology and an image recognition technology, the problems of high difficulty and low efficiency during manual repairing of defective circuit boards and circuit boards with components are solved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing device and method for repairing circuit board faults. Background technique [0002] Due to the manufacturing process and service conditions, in the process of manufacturing and actual use of the circuit board, it is inevitable that there will be defects such as: short circuit, convex copper, open circuit, etc. When the above defects appear on the circuit board, the traditional process needs to be manual The circuit board is selected and repaired. Since the wiring of the circuit board is relatively complicated and the adjacent distance is generally small, the manual repair is not only labor-intensive, but also requires the operator to have a high level of proficiency in operation. It will lead to the scrapping of circuit boards, etc., which will lead to high production costs. In addition, for circuit boards that have been welded with complete compone...
