A high temperature lighting device

Abstract

The invention provides a high-temperature lighting device, which includes a conveying mechanism and a test box. The left and right sides of the test box are provided with conveying ports. The conveying mechanism includes a U-shaped plate, a sliding rod and an electric push rod. The rear wall of the box is fixedly connected, and the two ends are respectively pierced through the two delivery ports and set outside the test box; the other side of the bottom plate is provided with a guide rail, and one end of the sliding rod is fixedly connected to the slider of the guide rail, and the sliding rod The other side of the sliding rod is provided with a fixed splint, and the sliding rod is also provided with a movable splint that can slide up and down along it. The movable splint is opposite to the fixed splint. The splint is provided with a matching slot opposite to the other end of the fixed splint; the electric push rod is set at one end of the bottom plate and is fixedly connected with the slider; the front wall of the test box is provided with several preheaters and heaters in sequence from left to right , sensor and marking unit, the inner wall of the test box is also equipped with a controller.

Description

technical field [0001] The invention relates to the technical field of LED manufacturing, in particular to a high-temperature lighting device. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode) is a semiconductor solid light-emitting device. Its principle is to use a solid semiconductor chip as a light-emitting material. When a forward voltage is applied to both ends of the chip, the carriers in the semiconductor recombine to cause photon emission. produce light. Due to the characteristics of low operating voltage, low energy consumption, high luminous efficiency, low heat, long service life, and environmental protection, LEDs are widely used in technical fields such as lighting and display lights. [0003] LED emits light through electronic recombination. When the current is low, the heat generated is very small, but in the application of high-power LED, especially in the display field, a large current is required, and a large amount of heat wil...

Problems solved by technology

In the production process (chip soldering, wire soldering), some links will have process defects such as solid crystal offset, bonding wire offset, empty soldering and virtual soldering. At present, these defects are mainly detected by high-power microscopes, personnel marking or Picking and other tools are used to remove defects. These human operations will cause omissions due to uneven personnel capabilities, which will affect the quality of the product.
