SMD LED injection molding support online detection device and detection method thereof

Abstract

The invention discloses an SMD LED injection molding support online detection device and a detection method thereof.The online detection device comprises a conveying belt, an injection molding station, a first camera, a maintenance station, a second camera, a laser and a controller, during detection, the first camera is used for photographing the LED injection molding support subjected to injection molding, and the controller processes the picture and searches for the coordinate position of a bad LED; if no bad LED exists, the LED injection molding support continues to be conveyed to the next station after passing through the maintenance station; if a bad LED exists, the LED injection molding support is conveyed to a maintenance station, a second camera is used for photographing the LED injection molding support and detecting the result of laser operation, and the controller processes the picture and searches for the coordinate position of the bad LED; the laser cuts the bad LED according to the coordinate position of the bad LED; according to the invention, online continuous detection is realized, the detection speed is improved, the detection speed can be synchronized with the injection molding rhythm, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to SMD LED production equipment, in particular to an on-line detection device and a detection method for an SMD LED injection molding bracket. Background technique [0002] SMD LED means Surface Mount Light Emitting Diode. At present, the production of SMD LED injection molding bracket products is realized by a production line composed of multiple equipment, and the equipment cannot be continuously connected to form a complete production line. Usually, the SMD LED injection molding bracket is formed into a continuous strip product by the injection molding machine. The product is first rolled into a semi-finished product roll, and then punched into an independent product by the punching equipment. Finally, the personnel inspected and found the position of bad injection molding in the bracket product, and repaired the bad position (manually cut off the bad position, and then manually repaired a LED bracket rubber particle at the ga...

AI Technical Summary

Problems solved by technology

[0003] There are many disadvantages in the above process: 1. From the injection molding production of the bracket to the inspection and discovery, the time span for defective repair is long

If there are continuous defects in the injection molding process, it will lead to a large number of defective products in the process

2. The manual detection method has high requirements for the detection personnel, low detection efficiency, and cannot avoid missed detection and wrong detection

3. The manual repair method cannot guarantee the cutting accuracy, and the repair quality cannot be guaranteed
