MiniLED Inspection

MINI LED

Inspection Requirements

Mini LED backlight is an important innovation direction in the path of LCD technology, which can significantly enhance the number of backlight partitions of display panels and improve display brightness and contrast.
Generally speaking, Mini LED refers to 100~300 micron size LED chips, with small volume and large overall usage, which need to realize batch imaging inspection.


The Solution

Fine Tuning Coaxial Zoom Lens

The zoom lens used in this optical solution has a built-in trim and coaxial light system, in addition to the lower end of the lens with a ring light universal interface.

With modular accessories, the magnification can widely cover 0.09-180x optical magnification, and the magnification fixation can be customized.

The repeatability is up to 1μm with minimal center shift.


H=9.3mm

V=6.95mm

1. In order to be able to see the Mini LED chip, magnification is required.

At a magnification of 0.52x, the long-edge field of view reaches 9.3mm and the short-edge field of view reaches 6.95mm.

Within this field of view size, the surface of a single Mini LED chip is clearly imaged, and a larger number of chips can be detected simultaneously.

H=1.45mm

V=1.1mm

Within that field of view size, the surface of a single Mini LED chip is clearer and smudges can be seen, but the number of chips that can be detected simultaneously is significantly reduced.

The two magnifications of the chip imaging effect and field of view meet the needs of the customer, and the customer can choose flexibly according to the different requirements for inspection quality and speed.

The working distance of the optical solution used for inspection is 120mm, and the working distance after adding the ring light source is 95mm, which also leaves a relatively loose space for the device to move.


Glass Tube——Blot Inspection

case share

Glass Tube

Inspection Requirements

This test product is made of glass and needs to be tested for dirty glass appearance.


The Solution

Telecentric Lens HR

Telecentric Lens: HR 

1. Infinitely long optical system that virtually eliminates chromatic aberrations and distortions for excellent picture quality.
2. Available in various magnifications, 40~220mm ultra-long working distance range for customization.
3. Excellent optical design, telecentricity less than 0.2°, aberration less than 0.3%.
4. Telecentric lens imaging is generally darker and needs to be used with a light source.


The imaging is clear and the dirt is easy to be identified.


The Lighting Source

Machine vision back light_Mvotem

Backlight is a flat panel light source, optimally designed LED arrays distributed at the bottom of the light source. The backlight passes through the special diffusion plate, which is 50% brighter than the side light guide.

Cylindrical Objects——Defects Inspection

case share

Cylinder Object

missing material                                        blot                                                  blot

Inspection Requirements

The test is a white cylinder object, requiring simultaneous detection of dirt and defects on the outer surface, inner surface and bottom. The overall detection speed of at least 150 pcs / min.


The Solution

Pinhole Lens: MV2818-2MCS

1. The object can be achieved from the outside to detect the inside cavity, and there's no need to place an optical probe in the cavity, reducing the risk.

2. This lens can inspect object with different shapes and sizes.

3. Wide field of view angle in the appropriate perspective with the lens to unfold the product surface, clearly display its characteristics.


1. Black spots show the defects on the surface, which are marked with red.

2. Small defects can be identified as long as they are visible on the picture

3. Side inspection by four stations simultaneously

4. Bottom defects

Lighting


[MPA Series]
Analog light source controller, is capable of stepless adjustment  which controls the brightness through adjusting the current. 
The KPA series is divided into 2-channel and 4-channel type, and each channel can precisely adjust the light source.

[MPD Series]
Digital light source controller, supports RS232 communication serial protocol. 
The 255 levels of brightness can be controlled by programming, in case that the brightness changes due to mis-operation.
