Position Detection of Crates in Spin Dryers via Ultrasonic Sensors
Position Detection of Crates in Spin Dryers via Ultrasonic Sensors
In the food industry, crates are dried in spin dryers after cleaning. In order for the water to drain completely out of the crates, they must be oriented with the bottom facing upwards. The ultrasonic distance sensor mounted above the conveyor line detects the passing boxes regardless of their color, shape or mesh size. If the sensor detects a box that is on the conveyor with the bottom facing downwards, it is rejected in the next step.

Detection of Baked Goods in Crates via Ultrasonic Sensor
Detection of Baked Goods in Crates via Ultrasonic Sensor
In the food industry, baked goods are transported in boxes through the various process steps. Before cleaning the boxes, it has to be ensured that there is no product left in the boxes. For this purpose, two ultrasonic distance sensors are installed next to each other above the conveyor belt, which emit ultrasonic waves and thus check the contents of the boxes. If baked goods are in a box, it is automatically ejected. The robust sensors in metric stainless steel housing with IP67 degree of protection reliably detect objects regardless of shape and color.

Position Check of PCBs Before Assembly Process by Vision System
Position Check of PCBs Before Assembly Process by Vision System
Before PCBs are loaded in SMD systems, they must be placed in the correct position and fed into the system. 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. In the subsequent assembly process, all components are applied in the correct position – thereby minimizing misplacement. The PCB is also uniquely identified by the vision system via decoding of a DataMatrix code.

Alignment of Beverage Cans for Label Application via Vision System
Alignment of Beverage Cans for Label Application via Vision System
Once beverage cans have been filled, labels are applied on the cans. The cans must be aligned in order to position the labels with millimeter precision. For this purpose, they are separated at high speed over a conveyor belt and turned in a jaw clamping system. A side-mounted vision system consisting of a machine vision camera, lens, ring light and analysis module records several images of the can per second and thus identifies features such as 1D codes or printed patterns. If these are detected and thus the position of the can is detected, the label application is triggered.

Spot Illumination for Robot-Guided Quality Inspection of Interior Parts
Spot Illumination for Robot-Guided Quality Inspection of Interior Parts
Before installing interior parts in passenger cars, the mounting elements must be checked for their presence and correct position. For this purpose, a smart camera with one spot light per side is mounted on a cobot. Due to the light weight and small size of the illuminations, they can be attached directly to the robotic arm. While the cobot scans the parts to be inspected, the spot lights provide precise illumination of the elements so that the camera can reliably detect each mounting element.

Position Determination during Depalletization with the Help of the Spot Light
Position Determination during Depalletization with the Help of the Spot Light
In logistics, pallets with the boxes on them are depalletized fully automatically by robots. To ensure that the robot can grip the boxes safely, the exact position of the grip holes of each box must be determined. With the help of four cameras and adjacent spot lights for precise illumination, the robot can reliably detect the gripping holes and grip the crates safely. The spot light is ideal for applications with limited space due to its small format.

2D Code
A 2D code, also known as a two-dimensional code, consists of a pattern of dark and light elements (bars, rectangles and squares with corresponding spaces in between) which are arranged in a 2D fashion. 2D codes have a more complex layout than 1D codes, and the technology required for acquiring and deciphering them is more complex as well as the scanner must always read the entire pattern depicted by the barcode in order to acquire and decipher 2D codes, and not just a horizontal line as is the case with 1D Codes. Two-dimensional codes contain more diverse information than one-dimensional codes, for example information for the identification of products, texts such as addresses, and delivery note numbers. In general, we differentiate within the 2D codes between the stacked codes (stacked code) and the matrix codes (DataMatrix code).

2D Code Scanner
A 2D code scanner is a scanner which operates according to the principle of an image processing system. It is equipped with a CCD or a CMOS element plus an integrated illumination and scans (scanning) a defined surface area depending on the selected scanning range. Thus, it is capable of reading 1D and 2D codes omnidirectionally.
