A light source self-adjusting mini LED detection structure

Abstract

The invention belongs to the field of semiconductor chip testing equipment, and relates to a light source self-adjusting Mini LED detection structure, which specifically designs a mounting seat, a mobile light source driving component (307), a mobile light source rotating connector (305), and a mobile light source component (309) The self-light source adjustment structure such as the camera module (2) adopts the cooperative drive of the mobile light source drive assembly and the mobile light source rotating connector to adjust the light source angle, so as to realize the automatic adjustment of the angle of the light source around the center of the camera for taking pictures, which is more efficient than manual adjustment. As a rotating guide structure, the module adopts the rolling cooperation of the arc support plate and the bearing as the rotating support structure, which has low production cost, more flexible and stable rotating guide and higher strength. The light source adjustment structure realizes the automatic adjustment of the angle of the light source around the camera center. Conducive to the development of equipment automation.

Description

technical field [0001] The invention belongs to the field of semiconductor chip detection equipment, and more particularly, relates to a Mini LED detection structure with self-adjustment of light source. Background technique [0002] With the continuous development of packaging technology, in the display field, the application field of ultra-high-definition high-density small-pitch LED display has become more and more extensive. In order to meet the demand for mass production, the electrical properties of the chip must be predictable and stable. The purity of the semiconductor chip, the semiconductor lattice structure, and various factors including the external environment must be strictly controlled. However, defects such as drops, dirt, scratches or dust may occur during the manufacturing process of semiconductor chips. It affects the yield of the chip, so it is necessary to detect the contamination of the chip. [0003] At present, the light source camera structures invo...

Problems solved by technology

[0004] (1) Low efficiency: manually adjusting the position of the light source and the focal length of the camera depends on the quality of the personnel and cannot guarantee the accuracy of each adjustment. It needs to be adjusted to the appropriate position continuously. Due to the low accuracy of manual adjustment, the preparation time for equipment adjustment in the early stage of production is limited. Long, low adjustment efficiency, manual adjustment is not conducive to the development of equipment in the direction of automation

[0005] (2) High cost: the arc-shaped guide rail is used as the guiding structure, and the production cost is relatively high

[0006] (3) The structural space occupancy rate is relatively large: the arc-shaped guide rail is used as a guiding structure, and the structural space occupancy rate is relatively large, which is not conducive to the overall miniaturization of the equipment
