Description

Technical Field

[0001] The present invention relates to the technical field of SMT, and in particular to a chip bulk material detection and packaging device. Background Art

[0002] In the Surface Mount Technology (SMT) industry, a series of fine particles and defects are inevitably generated during the production process. These problems are caused by a variety of factors that cannot be completely avoided. With the continuous advancement of SMT technology, the size of components is becoming increasingly miniaturized, and the circuit layout is becoming more compact and high-density. This trend has greatly aggravated the adverse effects of these tiny defects or particles on the quality of the final product of the printed circuit board (PCB). Specifically, even extremely small defects may cause circuit performance degradation, signal transmission obstruction, or component connection failure, which seriously affects the reliability and service life of electronic products. In order to maintain the stability of product quality, it is necessary to perform defect detection on the produced chips to increase the yield of finished products. In addition, after completing defect detection and screening out qualified chips, in order to ensure the efficiency and protection of their subsequent processing, these chips are usually sorted and packaged using taping packaging technology.

[0003] The patent with publication number CN216943685U discloses a flexible braiding machine based on machine vision, which is equipped with a top camera, an industrial computer, a vibration plate, a silo, a manipulator, a vacuum nozzle, a pulling motor, a carrier assembly, a heating assembly, a flying camera and a visual inspection camera. Through the cooperation of the top camera, the industrial computer, the silo and the vibration plate, the state detection and filling functions of the vibration plate and the silo can be realized, through the cooperation of the manipulator and the vacuum nozzle, the automatic material transfer function can be realized, and through the cooperation of the pulling motor, the carrier assembly and the heating assembly, the hot pressure sealing function of the material can be realized. During the operation, the flying camera and the visual inspection camera can be used to monitor the entire operation process to avoid errors.

[0004] However, the visual inspection camera of the above-mentioned flexible braiding machine can only capture the upper surface of the material and cannot comprehensively detect defects in the material. In actual industrial production, defects in the material may not only exist on the upper surface, but also on the lower surface. Due to the limitation of the camera's shooting range, defects on the lower surface are likely to be ignored, resulting in the production of defective products. At the same time, the flexible braiding machine can only load materials through a vibration plate combined with a silo, and the loading method is single and cannot meet the user's diversified loading needs.
