Laser welding spot AOI vision test equipment

Abstract

The invention discloses laser welding spot AOI vision testing equipment in the field of laser welding detection devices. The equipment comprises a vision testing device, a conveying device and a rotating assembly, wherein a vision testing cavity is formed in the middle of the vision testing device, a vision testing opening is formed in the upper end surface in the vision testing cavity, the conveying device comprises a conveying belt and a first driving motor, the first driving motor is fixedly installed on the right end face of the conveying belt, the conveying belt is driven by the first driving motor, the conveying belt penetrates through the vision testing cavity, a high-speed connector is placed at the upper end of the conveying belt, and a rotating assembly is installed in the inner cavity of the vision testing cavity. According to the invention,the upper end and the lower end of the high-speed connector can be visually tested, and secondary vision testing of the high-speed connector is not needed any more, so that the process of vision testing of the high-speed connector is reduced, and the efficiency of vision testing of the high-speed connector is improved.

Description

technical field [0001] The invention relates to the field of laser welding detection devices, in particular to AOI visual testing equipment for laser welding spots. Background technique [0002] Electronic connectors are also often referred to as circuit connectors, electrical connectors, and bridges two conductors on a circuit so that current or signals can flow from one conductor to another conductor device, which is required in the 5G communication system A large number of high-speed connectors are used. These high-speed connectors are all welded by laser. Since the high-speed connector undertakes high-speed signal transmission, it is necessary to ensure its welding quality and ensure that the solder joints reach a certain size. There is no misalignment of the position. In the past, the AOI visual test equipment used the pass-through test method. When the high-speed connector passed the AOI test equipment, the visual inspection was completed. However, the high-speed conne...

[0002] Electronic connectors are also often referred to as circuit connectors, electrical connectors, and bridges two conductors on a circuit so that current or signals can flow from one conductor to another conductor device, which is required in the 5G communication system A large number of high-speed connectors are used. These high-speed connectors are all welded by laser. Since the high-speed connector undertakes high-speed signal transmission, it is necessary to ensure its welding quality and ensure that the solder joints reach a certain size. There is no misalignment of the position. In the past, the AOI visual test equipment used the pass-through test method. When the high-speed connector passed the AOI test equipment, the visual inspection was completed. However, the high-speed connectors are symmetrically welded with contact pins on both sides, so that The pass-through detection method can only visually inspect one end of the high-speed connector. After the visual inspection of one end is completed, a second visual inspection is required, which increases the steps of AOI visual inspection and reduces the efficiency of AOI visual inspection of high-speed connectors.
