LED light Lens mounting PCB processing pick and place machine 45000CPH 12 Heads

TV backlight panel

The LCD screen itself does not emit light, and needs a backlight. LED backlight LCD TV uses LED as the backlight, which has five advantages over cold cathode fluorescent tube backlight

1. Ultra wide color gamut, can reach 105% ntse color gamut, so the color is more bright

2. Ultra thin appearance, up to 1.99 cm, more fashionable

3. Energy saving and environmental protection, energy consumption is 52% lower than that of cold cathode backlight, and there is no pump pollution of cold cathode tube

4. The service life is long, reaching nearly 100000 hours, and it can be used for 27 years if it is opened for 10 hours every day

5. It can achieve 100000:1 ultra-high contrast and higher definition

Production requirements of LED lens

1. Requirements for mounting glue

There are two types of common LED lens mounting glue: one is UV glue, and the other is thermosetting glue, also known as thermosetting resin adhesive. Thermosetting glue is generally used for those with high quality requirements

UV adhesive, also known as photosensitive adhesive and UV curable adhesive, is a kind of adhesive that can be cured only by UV irradiation. It can be used as an adhesive, and also as a glue for paints, coatings, inks, etc. UV is ultraviolet light. UV adhesive generally needs to be equipped with an ultraviolet lamp. It can be initially cured within 1-5 seconds under the irradiation of UV lamp, and can be bonded within 20-30 seconds. UV glue can reach high intensity after being irradiated by UV lamp, which can meet the needs of automatic production line rhythm

SMT process flow of LED lens

For the products that need to be attached to the lens, it is often necessary to mount the LED before the lens, and the two kinds of mounting are two separate mounting lines. Because the temperature requirements of the lamp beads and the lens are different, the lamp beads need to be welded in the boiler before the lens is attached

Function of each part:

Part A: Two screw servo motors to provide adjusting rail width power for each rail.

Part B: Two transmission rails for each module transport in opposite directions.

Part C: Newest High-end Magnetic linear motor provides power for the mounting heads

Part D: Its Tank chain, protects the wires and lines free of abrasion.

Part E: Flight identification camera with high resolution for accurate vision alignment correction
