Light splitting and taping integrated LED detection method and device

Abstract

The invention relates to a light splitting and taping integrated LED detection method and device. The method comprises the following steps that (1) LEDs are conveyed to a first index plate; (2) the first index plate is rotated to an exchange station, and the LEDs are exchanged to a second index plate; (3) top surface images of the LEDs are detected through an image detection device, whether damageand stains are left on the material appearances of the LEDs or not is detected, a light splitting test is carried out, and the LEDs are classified into different types; (4) a certain type of LEDs areconveyed to the first index plate, and other types of LEDs are blown to different types of material receiving material barrels on the second index plate; (5) a certain type of LEDs are rotated to a direction needing taping through polarity rotation, and position correction is carried out; and (6) taping is carried out. According to the light splitting and taping integrated LED detection method and device, the light splitting process and the taping process are integrated, light splitting testing can be conducted during taping so that the situation that materials are mixed due to multiple timesof manual operation in the LED conveying process can be effectively avoided, and the consistency of LEDs during taping is improved.

Description

technical field [0001] The invention belongs to the technical field of LED braiding technology, and in particular relates to an LED detection method and equipment integrating light splitting and braiding. Background technique [0002] Light-emitting diodes (LEDs) have been widely used in all aspects of production and life due to their unique advantages such as energy saving and long life, and the quality of LEDs has received unprecedented attention. In occasions where LED lighting sources have high requirements for display, especially large-screen displays, the difficulty and importance of LED quality are particularly prominent, and the requirements for the consistency of LED broadcast and television performance are very high, otherwise phenomena such as brightness and mosaic will appear , Color uniformity and saturation, etc., affect people's visual effects. Therefore, it is necessary to test and sort LED single tubes, and to accurately and quickly test and sort LEDs with ...

Problems solved by technology

[0005] However, after the product is separated, the material is manually collected and then transported to another equipment for the braiding process. Mixing of materials is likely to occur in the middle, which reduces the quality of the product.

In addition, most of the braiding equipment does not have the function of spectral detection, and can only test the electrical parameters of the material, which makes the consistency of the material worse, and there is a chance that other variegated colors may be mixed in the spectrum and cannot be detected and screened; at the same time, due to the difference between materials and equipment The number of collisions is large, resulting in a significantly larger number and degree of damage to the material. Therefore, for the high-end field, the products produced by this process and production equipment obviously cannot meet the requirements of the market.
