AOI automatic optical detector is mainly used in SMT enterprises for offline or online inspection of printed circuit boards and components of the appearance of the process quality, solder paste printing, deflection, less tin, more tin, circuit breaking, pollution; Missing parts, deviation, skew, monument, side, turn over parts, reverse polarity, wrong parts, damaged parts; And solder spot defects of tin, tin, tin and other problems detection and identification identification has a great help.
In manufacturing environments, bar code scanners and machine vision products help reduce costs, increase output, improve product quality and comply with industry regulations. Barcode scanner can be used for real-time operational monitoring of data collection and preservation of historical data (tracking). Industrial machine vision systems can be used for automatic inspection and process control.
Successful industrial machine vision and barcode applications are based on stable hardware and reliable software in factory automation systems. Masken's high performance and high speed readers, machine vision systems and machine vision lighting products are supported by outstanding customer service and over 25 years of industry experience. By choosing Mesken products, you can confidently collect data, implement the necessary controls to minimize downtime, improve efficiency, and meet higher standards in addition to complying with industry and government regulations.
Barcode scanner
Bar codes are machine-readable symbols that can be printed on labels for application (printing and use) or printed directly on parts, products or packages (DPM). Generally speaking, barcodes contain data items with specific meanings, such as the unique code of the product, the batch of production, the type of item and so on. Barcode scanners are used to capture and read this data, making it possible to track and identify components along the supply chain. In production, the data can be used for automated operations and quality control, saving time, money and manpower.
Bar code scanner solutions for manufacturing enterprises
In today's manufacturing environment, fast and accurate data collection is essential for efficient and rapid operation of the production line. Stable, online, networked barcode scanners can both capture data and drive activity in factory operations. Bar codes and qr codes have become an integral part of most lean manufacturing enterprises.
Application of bar code technology
Barcode technology can assist critical applications such as quality control, online monitoring (WIP), classification and batch tracking. A common use of barcode technology is error prevention or error correction at a step in the process. For example, many packaging systems use bar code technology to ensure that items match the box before they are packed.
Barcode scanner and 2D code reader
Barcode scanner (also called reader) is used to extract and decode data from 1D (linear) bar codes or 2D (two-dimensional) bar codes. Laser bar code scanners are most commonly used to read 1D bar codes because of their high speed and ease of use. Readers (which take pictures like digital cameras) can be used to read 1D and 2D encoding and optical characters (OCR). High speed and accuracy are key requirements of manufacturing environment; Mesken can provide reliable reading solutions for bar codes, 2D labels and optical characters.
Machine vision system
Machine vision automatically extracts useful information from digital images. In industrial Settings, machine vision systems take bar code readers a step further, using image capture and analysis to automate tasks such as monitoring, measuring and counting, rather than just reading bar codes and optical characters.
Manufacturer of enterprise machine vision solutions
Machine vision systems help manufacturers worldwide improve product quality, reduce costs and ensure customer satisfaction. Vision systems on smart cameras and PCS are standard in automated inspection systems. Inspectors can manually check the quality of work on parts, and machine vision systems can use advanced hardware and software to do the same job, but faster, more reliable, and more accurate.
Application of machine vision
Machine vision is best suited for inspection work requiring high speed, high precision, continuous operation and/or repeated measurements. For example, machine vision can be used to prevent leakage (missing parts) in plastic injection operations. During beverage filling operation, machine vision system can identify filling level.
Components of a machine vision system
A complete machine vision system consists of a combination of hardware and software that varies according to application requirements. In particular, it is essential for light sources, lenses, cameras, processing units, communication facilities, I/O and host software. Mesken's integrated machine vision products are based on our industry-leading scalable machine vision software Visionscape. This software fits into our smart camera, Gigabit Ethernet (GigE) camera on the PC, and machine vision system on the motherboard. Mesken also offers a full range of accessory products including lenses, wiring and NERLITE machine vision light sources.
Machine vision light source
In any machine vision or barcode imaging application, the appropriate light source is often the most important variable for achieving accurate, repeatable results. Properly planned lighting schemes can optimize the performance of machine vision systems.
Machine vision lighting solution
Effective machine vision lighting can provide a stable environment that maximizes feature contrast while reducing background contrast. Optimize system performance (high SNR) by allowing the camera to "see" what needs to be checked.
Notes for machine vision light source
When setting up a machine vision system, the geometry, divergence and wavelength (color) of the light as well as environmental factors should be the primary considerations. Mesken's NERLITE brand light source is very stable. This LED light source includes annular light source, dome light source, back light source, scattered coaxial light source (DOAL) and other designs for you to choose from. All of these light sources have white light as well as other wavelengths, including red, blue, UV, and infrared.
Application of machine vision light source in bar code
Precise light source solutions can improve the performance of many automatic ID or barcode applications and machine vision applications using imaging devices. Denser light sources allow for faster shutter speeds, which in turn increase production line speeds. Also, due to the use of many TWO-DIMENSIONAL codes (DPM), the correct ray geometry can achieve stable decoding rates.
Masken offers a complete line of barcode and QR code reading products, machine vision systems and machine vision light sources for industrial automation control applications. With our sophisticated global integration network and reliable bar code sensors and machine vision systems, you can build a stable data collection system or integrate all the controls necessary to maximize efficiency, security and profitability.
