Description

Technical Field

[0002] Light-emitting diodes, or LEDs for short, are a commonly used light-emitting device that emits light by releasing energy through the recombination of electrons and holes. They are widely used in the field of lighting. Light-emitting diodes can efficiently convert electrical energy into light energy. They have a wide range of uses in modern society, such as lighting, flat-panel displays, and medical devices. This electronic component appeared as early as 1962. In the early days, it could only emit low-intensity red light. Later, other monochromatic versions were developed, and the light that could be emitted has spread across visible light, infrared light, and ultraviolet light, and the luminosity has also increased to a considerable luminosity. The use has also changed from being used as indicator lights and display boards at the beginning. With the continuous advancement of technology, light-emitting diodes have been widely used in displays and lighting. However, when processing and assembling existing light-emitting diodes, it is necessary to inspect the internal wafers to detect whether there are quality problems with the finished wafers. Due to the small size of the wafers, the existing detection methods are all manual detection under a microscope, which is inefficient and not conducive to rapid detection. In addition, during the detection process, it is inconvenient to locate the position of the wafer, and it is easy for the wafer position to shift, which makes it inconvenient to detect the wafer, affecting the efficiency of the detection. Therefore, we need to propose a diode chip detection device. Utility Model Content
