High-temperature lighting device

Abstract

The invention provides a high-temperature lighting device which comprises a conveying mechanism and a test box; conveying openings are formed in the left side and the right side of the test box; a conveying mechanism comprises a U-shaped plate, a sliding rod and an electric push rod; one side of a bottom plate of the U-shaped plate is fixedly connected with the rear wall of the test box; the two ends of the U-shaped plate penetrate through the two conveying openings respectively and are arranged outside the test box; a guide rail is arranged on the other side of the bottom plate; one side of one end of the sliding rod is fixedly connected with a sliding block of the guide rail; a fixed clamping plate is arranged on the other side of the sliding rod; a movable clamping plate capable of sliding up and down along the sliding rod is arranged on the sliding rod; a movable clamping plate and the fixed clamping plate are oppositely arranged; a tension spring is connected between the ends, close to the sliding rod, of the movable clamping plate and the fixed clamping plate; and matched inserting grooves are oppositely formed in the other ends of the movable clamping plate and the fixed clamping plate; the electric push rod is arranged at one end of the bottom plate and fixedly connected with the sliding block; a plurality of preheaters, a heater, an inductor and a marking unit are sequentially arranged on the front wall of the test box from left to right; and a controller is arranged on the inner wall of the test box.

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...

AI Technical Summary

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.
