In recent years, electronic products tend to be light and thin, making electronic components smaller and smaller, the traditional dispensing machine by naked eye manual teaching and programming operation method has been unable to accurately position. The visual dispensing system can be installed for the dispensing machine with different pixels of the CCD industrial lens, different magnification, and a variety of light source combination, can achieve very accurate positioning accuracy.
Dispensing technology is a crucial connection point in the product production line, and the adhesive and packaging of products need dispensing process. At present, automatic dispensing technology is developing towards the direction of high precision and high standard, and the traditional dispensing machine has long been unable to meet the needs of today's society. Visual dispensing system adopts panoramic large area vision high-precision positioning system, cad drawing + machine vision + motion control + database management perfect combination, this design completely solves the need for fixture, poor accuracy, low efficiency, low yield of artificial intervention.
With the development of modern electronics industry, especially the emergence of smart phones, tablet computers and other portable electronic products, the demand for dispensing equipment shows explosive growth. As the design of portable electronic products tends to be miniaturized and intelligent, and the internal chips are concentrated, the traditional non-visual dispensing equipment has been difficult to meet the production requirements, and the intelligent dispensing equipment with visual system has gradually become the mainstream.
At present, most of the dispensing machines with vision system on the market are developed on the traditional IPC, the whole system occupies a large space, the cost and price are relatively high, a set of compact, low cost, intelligent dispensing robot with vision system is more and more urgent and important for manufacturing enterprises, miniaturization, intelligence, cost-effective is also the trend of future equipment development. The data processing speed and computing power of micro processing chips (such as ARM and DSP) have also been greatly improved in recent years, and even exceed the processing power of IPC, which also provides more possibilities for the miniaturization of equipment. Many camera manufacturers have started the research on embedded vision.
Set embedded system, motion control, visual processing in one of the control system ideas, relying on the current micro-processing chip operation and processing ability, from the principle analysis can well realize the current IPC as the main control system, supporting fluid control function, can develop a set of embedded intelligent [visual dispensing system].
The development of the system mainly involves embedded system software and hardware technology, cross-platform application software development technology, motion trajectory control technology, high-precision vision algorithm technology, geometric transformation algorithm optimization technology, scanning and glue algorithm in motion, fluid control technology, Among them, dense algorithm and high precision visual recognition and matching algorithm in embedded system have great challenges in practical development.
Advantages of visual intelligent dispensing
1.CCD transmits the image data to the handheld teacher through USB. The handheld teacher is the core of vision, directly processes the transmitted image data, and outputs the corresponding control instructions to the dispensing robot through the serial port. Compared with the intelligent visual dispensing system based on IPC, there is no need for additional visual acquisition card and IPC. All system functions are focused on the touch screen teaching device. The construction and use of the whole system are very simple, because there are few modules and the space required is very small.
2. Low energy consumption
The design of embedded system is for specific applications, because the additional function modules are cut, so the core functions are integrated in a single system, the power consumption is very low, the system power is less than 10W during operation, there is a very high energy efficiency.
3. Low overall cost
The visual acquisition card, IPC and other related accessories in the intelligent visual dispensing system based on IPC account for 20%~30% of the cost of the whole system, while the embedded visual intelligent dispensing system robot does not need these parts at all, so as to achieve a significant reduction in the overall cost.
