Abstract

The invention relates to a patching method and device. According to the patching method and device, circuit board printing solder paste is assisted by adoption of a positioning member; and when patching is carried out, an image of a circuit board is acquired through a visual acquisition mechanism to calculate an accurate coordinate and judge whether a patching position is correct or not. The patching device comprises a machine platform, a circuit board fixing jig, a visual detection mechanism, a patching mechanism and a circuit board positioning jig, wherein the circuit board fixing jig is arranged on the machine platform and is used for placing the circuit board; the visual detection mechanism is arranged on one side of the machine platform and is used for detecting the circuit board; thepatching mechanism is arranged on the other side of the machine platform and is used for patching the circuit board; and the circuit board positioning jig is located between the patching mechanism and the visual detection mechanism. According to the patching method and device, repeated coordinate acquisition comparison and detection are carried out in the patching process, so that the correctnessof the patching position is ensured, the product quality if ensured, the patching of small components and components complicated in arrangement is satisfied, and the adaptability is relatively strong.

Description

technical field [0001] The invention relates to the technical field of PCB patch processing, in particular to a patch method and device. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. SMT (Surface Mounted Technology) is the surface mount technology, which is the most popular technology and process in the electronic assembly industry. Devices) are mounted on the surface of the PCB or the surface of other substrates, and are soldered and assembled by reflow soldering or dip soldering. With the continuous development and progress of technology, all kinds of electronic components are becoming more and more refined, and they are constantly developing towards miniaturization, and the requirements for placement are also getting higher and higher. For...
