环形照明系统的照明方法

环形照明系统在工业图像处理中的使用因工作距离而异。此时通常使用以下照明技术：

倾斜角度照明

当 LRL 环形照明系统以小角度与测试表面对准时，可以减少眩光并可突出显示边缘、划痕和刻印标记。

用于工作距离较大的明场

LRL 环形照明系统的照明强度高达 150,000 lux，可发射强烈的光线，即使在工作距离较大时也能提供最佳照明。

Con­ver­gen­ce Light At­tach­ment

The con­ver­gen­ce light at­tach­ment is a kind of angle chan­ger that can be used to ef­fec­ti­vely focus light. This mi­ni­mi­zes ring ef­fects, which often lead to une­ven illu­mi­na­tion of the cen­ter of the test ob­ject.

Di­rect Moun­ting of the LRLx100 on C Mount Len­ses

The small LRLx100 ring light can be at­ta­ched di­rectly to C mount len­ses using a spe­cial adap­ter. In this way, the illu­mi­na­tion sys­tem is di­rectly in­te­gra­ted without the need for ad­di­tio­nal brac­kets or moun­ting ele­ments. The ring light is au­to­ma­ti­cally cen­te­red and po­si­tio­ned in line with the ca­me­ra’s field of view by di­rect con­nec­tion to the C mount lens, en­su­ring that the test ob­ject is al­ways ideally illu­mi­na­ted. This con­fi­gu­ra­tion re­qui­res only one ca­me­ra or light mount, sim­plif­ying setup and mi­ni­mi­zing space re­qui­re­ments, which is es­pe­cially be­ne­fi­cial for qua­lity con­trol or sur­fa­ce ins­pec­tion in con­fi­ned ap­pli­ca­tion en­vi­ron­ments.

Ap­pli­ca­tions

Decoding DataMatrix Codes

In the automotive industry, the quality of individual components of passenger car interior doors, such as window controls or armrests, must be visually checked for different types of door at the same time. A vision system with several cameras is installed for this purpose.

End-of-Line Visual Quality Inspection

Engine manufacturing in the automotive industry requires an end-of-line quality control at the end of each production line. This prevents faulty engines from leaving the production line. For this purpose, a vision system consisting of cameras, lenses and illumination is installed on several robot arms.

Visual Quality Assurance for Oil Canisters

Injection molded parts made of plastic must be visually inspected for defined quality characteristics after production. For example, a vision system checks the geometry, color, inclusions, overspray or underspray or spout separations on oil canisters.

Position Check of PCBs

Before PCBs are loaded in SMD systems, they must be placed in the correct position. For the position test, a vision system is installed above the PCBs, which records a crosshair printed on the circuit board as a reference point. From this, the so-called “offset” is determined and transferred to the machine control.

Illumination of Mounting Holes

Before installing car seats, a machine vision camera is used to check whether the mounting holes have the required threads. To do this, the holes are illuminated with ring lights. A compact design with multiple cameras and ring lights allows simultaneous inspection of multiple holes in confined spaces.

Orientation of Beverage Cans

Once beverage cans have been filled, labels are applied on the cans with millimeter precision. A side-mounted vision system captures multiple images of the can per second, identifying features such as 1D codes. If these are detected and thus the position of the can is detected, the label application is triggered.

Label Check on Spreadable Cheese Packaging

When filling different types of spreadable cheese, it must be ensured that the correct lid with logo is applied to each package. For this purpose, a vision system is installed on the conveyor line, which checks and compares the lids from above using a camera during operation.​​​​​​​
