LEDs are divided into rigid boards, flexible boards, with leads, without leads, and irregular neon lights.
We typically use a vacuum board transfer mechanism to move unmounted LED substrates, achieving automated handling.
The process then proceeds with a solder paste printer, pick-and-place machine, reflow oven, followed by manual or machine inspection and repair.
If the LED requires lens mounting, a dedicated lens placement machine is configured after the SMT production line.
First, a specialized lens dispensing machine is used to apply adhesive, followed by a dedicated lens placement machine. The lens feeding method uses a vibrating feeder.
The suction nozzle is customized based on the lens diameter. If a single type of lens varies, and production volume is large, the suction nozzle spacing of the lens machine can be customized to pick up multiple lenses simultaneously, improving efficiency.
After the lenses are mounted, a reflow oven is used to heat and attach the lenses, completing the process.
