Problems solved by technology

[0002]Most of the current dispensing equipment can only dispense one LED lamp bead at a time, and cannot dispense multiple LED lights arranged in an array at the same time Beads, the dispensing efficiency is low. In addition, although the existing dispensing equipment can detect whether there is an electrical problem with a single LED lamp bead before dispensing, and control not to dispense glue to the problem chip, but for the LED lamp beads arranged in an array, When one or more chips have electrical problems, how does the existing dispensing equipment accurately identify the chip and control the dispensing equipment corresponding to the chip to selectively not dispense glue, but there is no relevant literature report. How to accurately remove one or more problematic chips in the array of LED lamp beads is also a further problem in this field

Embodiment 1

[0048] An automatic detection, automatic glue dispensing and automatic sorting device for LED lamp beads arranged in an array, including chip detection equipment for detecting whether each chip in the LED lamp beads 118 arranged in an array is working normally, Dispensing equipment for dispensing each chip in the LED lamp beads of the cloth, the dispensing equipment includes a plurality of dispensing machines 111 arranged in an array, and each dispensing machine 111 corresponds to an LED lamp bead that needs to be dispensed, so The chip detection device transmits the detection result of the working state of each chip in the LED lamp beads arranged in the array to the control system 1, and the control system 1 identifies the abnormally working chip and its corresponding coordinate information, and the system control and control are related to the control system 1. The electric valve 1-6 (see Fig. 1-D) of the glue dispenser corresponding to the chip coordinates is closed to stop ...

Embodiment 2

[0066] The chip detection equipment and detection substrate of Example 2 are different from those of Example 1. The positive level of each chip in the arrayed LED lamp beads of Example 2 is connected together to form a positive level (V1) detection terminal, The negative stage of each chip in the LED lamp beads arranged in the array is connected together to form a negative stage (V2) detection end, the positive stage (V1) detection end and the negative stage (V2) detection end The heads are preferably fixed adjacent to each other, and the relative positions of the positive level (V1) detection end and the negative level (V2) detection end can also be arbitrarily set, that is, each of the LED lamp beads arranged in the array The positive stage of the chip and the negative electrode of each chip are respectively connected in parallel. In this embodiment, the concept of parallel connection is realized by designing a suitable detection substrate.

Abstract

The invention relates to an automatic detection, automatic dispensing and automatic sorting device for LED lamp beads arranged in an array, which comprises a chip detection device for detecting whether each chip in the LED lamp beads arranged in the array works normally or not and a dispensing device for dispensing the chips in the LED lamp beads arranged in the array, the dispensing device comprises a plurality of dispensing machines arranged in an array, and the chip detection device is used for detecting whether each chip in the LED lamp beads arranged in the array works normally or not. Each dispensing machine corresponds to one LED lamp bead needing to be dispensed, the chip detection equipment transmits a working state detection result of each chip in the LED lamp beads which are arranged in an array to the control system, and the control system recognizes the chips which work abnormally and coordinate information corresponding to the chips; the system controls the electric valve of the dispensing machine corresponding to the coordinates of the chip to be closed so as to stop dispensing on the abnormally working chip, the system further comprises a sorting device electrically connected with the control system, and the control system subsequently controls the sorting device to remove the abnormally working chip. The device can save fluorescent powder, glue and manpower.

Description

technical field [0001] The invention relates to the technical field of LED lamp bead dispensing, in particular to a method of synchronously dispensing a plurality of LED lamp beads arranged in an array, and before dispensing, each of the LED lamp beads arranged in the array is synchronously dispensed. The conductivity of each chip is detected synchronously, the LED lamp beads with problems are identified, and the dispensing equipment is controlled not to dispense the LED lamp beads with the above problems. It also involves sorting equipment, which can identify the problem LED lights. Beads are automatically removed. Background technique [0002] Most of the current dispensing equipment can only dispense one LED lamp bead at a time, and cannot dispense multiple LED lamp beads arranged in an array at the same time, and the dispensing efficiency is low. In addition, although the existing dispensing equipment Before dispensing, it can detect whether there is an electrical probl...
