Abstract

The invention relates to a CCD alignment pulse thermocompression welding system and a welding method, and relates to the technical field of thermocompression welding. According to the CCD alignment pulse thermocompression welding system and the welding method, images shot by a laser flatness measuring instrument and a CCD camera are analyzed through an image analysis module, the welding spot thickness and the flatness of a flexible circuit board and a rigid circuit board are analyzed, the welding spot thickness range and the flatness are preset in the image analysis module, the actual welding spot thickness and the flatness are compared with preset values, the thermocompression temperature and the thermocompression pressure of a welding head of pulse thermocompression welding are adjusted according to a comparison result, preset maximum thermocompression pressure is set in a control module, and when the thermocompression pressure is adjusted to exceed the preset maximum thermocompression pressure, the pulse voltage of the welding head is adjusted, so that the welding precision is improved, the welding quality is improved, and therefore the quality of the circuit boards is improved.

Description

technical field [0001] The invention relates to the technical field of thermocompression welding, in particular to a CCD para-position pulse thermocompression welding system and a welding method. Background technique [0002] As an important equipment for welding flexible circuit boards and rigid circuit boards, the hot-press welding machine has a great influence on the quality of the circuit boards after welding. It plays a decisive role, and most of the existing alignment of solder joints is through manual alignment welding. [0003] The existing hot-press welding machine basically adopts the pulse heating technology, and the temperature control of the welding point is precise. The temperature of the hot-press machine can be represented by a real-time temperature curve, which is easy to understand and greatly facilitates the work of the operator. [0004] As a camera electrical coupling element, CCD can make the captured image achieve high definition, so it is used in man...
