Laser profile sensors measure dimensional accuracy of sectional garage doors
Laser profile scanners from Micro-Epsilon are being used to measure the dimensional accuracy of key and slot joints on sectional garage doors.
Micro-Epsilon's scanCONTROL 2710 series of 2D/3D laser profile sensors are set up to measure the key and slot joints - the specified dimensions of which are absolutely critical in the manufacture of sectional doors for garages, parquet and laminate flooring. The door sections are opened and closed frequently and so require a robust but permanently flexible key and slot joint. This is particularly important where there are significant temperature fluctuations or inaccurate dimensions, which could result in the door being positioned incorrectly making it difficult to lock.
During manufacture, the imprinted metal film is processed from a roll and formed into the required shape. In order to improve thermal insulation, polyurethane foam is traditionally used to fill the cavity spaces between the sectional door panels. Under specific conditions, this foam material expands, providing extra stability for the panels.
After curing, the shape and dimensional accuracy of the door panels - particularly around the key and slot joint areas - must be inspected in order to detect any deviations from the specification. Any decoration used on the door panels must also not affect the film. Depending on customer requirements, the door sections are then cut to the required shape using fly shears.
The measurement of the key and slot joints is carried out using Micro-Epsilon's scanCONTROL 2710-50 laser profile scanner. To translate the measurement data into the format required by the customer, the output unit of the laser scanner is used. A datum point, to which all calculations and measurements are performed, is defined within the profile. These results are transmitted to the production line control room so that any deviations within the strip process can be compensated for.
The scanCONTROL 2710 series is ideal for industrial automation tasks, including robotics and machine building applications, where space is often restricted. The compact design, integrated controller and easy-to-use set up software, enable users to quickly mount the sensor onto robot arms, inspection equipment or into their production lines. The sensor can be used to measure the profile of adhesive beading, weld seams, channels, grooves, gaps, angles and steps, as well as for parts recognition, traceability and robot guidance/positioning.
Once the scanCONTROL 2710 has been configured using the set up software supplied, the system operates in standalone mode. Using the integrated controller, the sensor can acquire data, calculate profiles and generate measured values for the complete field of measurement at high speed (64,000 points/100 profiles per second) and full resolution. The user requires no other components to evaluate the measurement data (no PC or special programming software is required) and the unit can be easily re-configured and adapted for different applications.
The system works in two ways: either in a stationary mode, with the sensor fixed and looking at moving targets, or in a scanning mode, where the sensor works in combination with a motion control device or robot. The sensor uses an innovative CMOS array with a real time, high-speed electronic shutter (rather than conventional rolling shutters), which captures the entire profile and processes the information instantaneously.
The system is available with measuring ranges from 25mm to 300mm in the Z (vertical) axis and 22mm to 148mm in the x (horizontal) axis. A small output module for DIN rail mounting is also available to convert the sensor output data into common fieldbus systems, including CANbus, Profibus DP, Ethercat and IEEE. Measurement results can be output using digital or analogue modules for further processing and evaluation. The sensor also provides synchronous triggering of multiple scanCONTROL sensors.
Micro-Epsilon (www.micro-epsilon.co.uk) is a major global manufacturer of sensors, headquartered in Germany. The companys range of displacement sensors measure everything from to distance, position, vibration, dimensions and thickness, using both contact and non-contact measurement techniques. These techniques include 1D, 2D and even 3D laser-optical sensors and systems, eddy-current, capacitive, LVDT & inductive, potentiometric and draw-wire principles. Additionally Micro Epsilon has developed its own range of non-contact infrared temperature sensors that can measure virtually any target temperature from -40 to +3,300°C.
With more than 35 years experience in the industry, Micro-Epsilon isnt just a sensor manufacturer. The company is highly innovative and understands the importance of providing complete solutions and support services for its customers. The firm is renowned for its expertise in consulting, development and application of industrial sensors to complex, customer-specific solutions for measurement, inspection and automation. The focus is on selling technical advantage to its customers.
