PCBA board cleaning and detecting equipment

Abstract

The invention discloses PCBA board cleaning and detecting equipment. The PCBA board cleaning and detecting equipment comprises a pre-impurity-removing station, a cleaning station and a detecting station which are arranged in sequence. The impurity spraying device is arranged at the impurity pre-removing station and is used for pre-cleaning foreign matters on the PCBA board; the rolling brush dust sticking device is arranged at the cleaning station and is used for sticking and cleaning foreign matters on the PCBA board; the visual detection device is arranged at the detection station and is used for comparing and detecting the structural characteristics of the PCBA board; and the performance detection device is arranged at the detection station and is used for testing the electrical performance of the PCBA. In order to optimize the cleaning refinement of the rolling brush dust sticking device, the impurity spraying device is creatively arranged to carry out impurity pre-removal cleaning treatment on the outer surface of the PCBA in advance, and the cleaning of the board surface of the PCBA is improved; and the visual detection device and the performance detection device are arranged in a combined manner, so that the structural characteristics of the board surface of the PCBA are ensured, and the electrical performance of internal electronic components has test timeliness and accuracy.

Description

technical field [0001] The invention relates to the technical field of PCBA production, in particular to a PCBA board surface cleaning and testing equipment. Background technique [0002] At present, packaging technology is usually used to package PCBA boards. However, in the production process, dirty foreign matter, such as dust, fibers, debris, etc., will inevitably adhere to the PCBA board surface. If these dirt are not cleaned in time, it will be very easy to Affect the electrical performance of PCBA, and then affect its product quality; the existing cleaning device can only meet the requirements of simple dust removal operation, and cannot comprehensively clean the dirt with small particle size and excessive viscosity, and the cleaning effect is poor. It can only clean a single board at a time. If you want to clean a double-sided PCBA, you need to turn it over to clean after completing the single-sided cleaning, and the cleaning efficiency is extremely low. [0003] In...

[0002] At present, packaging technology is usually used to package PCBA boards. However, in the production process, dirty foreign matter, such as dust, fibers, debris, etc., will inevitably adhere to the PCBA board surface. If these dirt are not cleaned in time, it will be very easy to Affect the electrical performance of PCBA, and then affect its product quality; the existing cleaning device can only meet the requirements of simple dust removal operation, and cannot comprehensively clean the dirt with small particle size and excessive viscosity, and the cleaning effect is poor. It can only clean a single board at a time. If you want to clean a double-sided PCBA, you need to turn it over after cleaning the single side. The cleaning efficiency is extremely low.

[0003] In addition, as the integration of the PCBA board becomes higher and higher, the inspection items and accuracy requirements of the PCBA board are also higher. The basic inspection items of the PCBA generally include structural feature inspection and electrical performance inspection. Traditional structural feature inspection Usually it is manual registration detection, which needs to pre-manufacture the registration of the matching structure of the PCBA to be tested, and place the registration on the PCBA during the inspection, and judge whether it matches with the naked eye. This method has poor detection accuracy and slow efficiency. The rate of defective products and labor costs are high; however, there are many electrical performance testing items, and the existing testing devices cannot complete multiple electrical performance testing items at the same time. To complete various tests, it takes a lot of process flow time and testing time. , it is easy to cause misjudgment and missed judgment, and the detection efficiency and effect are poor
