Abstract

The invention discloses a multi-pin-based defect detection device and a detection method thereof. The defect detection device comprises a camera for collecting a sample image, wherein two LED light sources adopting a high-angle lighting method are symmetrically arranged below the camera, a transmitting platform for placing and transporting a sample is arranged below the LED light sources, and the side edge of the transmitting platform is provided with a removing mechanism for removing an unqualified sample; the camera is connected with an industrial personal computer which is for receiving and processing the collected sample image, and the industrial personal computer is also connected with a displayer for displaying an image processing result made by the industrial personal computer. The multi-pin-based defect detection device and the detection method thereof realize automatic online detection on a multi-pin defect, the production cost is lowered, the detection efficiency is improved, the away-detection precision is greatly increased, and a detection missing phenomenon and a detection error phenomenon in conventional manual direction are well avoided.

Description

technical field [0001] The invention relates to the field of product quality detection, in particular to a multi-pin-based defect detection device and a detection method thereof. Background technique [0002] In manufacturing, a section of the end of the lead is soldered to form a solder joint with the pad on the printed board. Pins, also known as pins, are called Pins in English. It is the connection between the internal circuit of the integrated circuit (chip) and the peripheral circuit, and all the pins constitute the interface of the chip. The quality of the pins directly affects the performance of the chip and is related to the quality of the chip. [0003] At present, after the production process of pin products is completed, the number of pins of the chip is mainly detected by manual visual inspection methods, and the pin spacing of the chip is measured with a caliper. This traditional visual inspection method consumes huge human resources and brings huge economic ...
