Light bar gluing machine is an automatic irrigation machine. Mainly used for light bulb at the head of the plastic package, to achieve a fixed internal power supply, protection and so on. Light bar glue machine commonly used glue with silicone, automatic machine ratio, automatic irrigation, three-axis manipulator can complete a variety of paths to achieve a batch filling, production capacity, quality is very high. The efficiency of a light bar gluing machine top 5-7 artificial.
Why use silicone? The basic structural unit of the organosilicon product is composed of silicon-oxygen chain, and the side chain is connected with other various organic groups through silicon atoms. Therefore, in the structure of silicone products contains both "organic groups", but also contains "inorganic structure", this special composition and molecular structure so that it combines the characteristics of organic matter and inorganic function in one. Compared with other polymer materials, silicone products, the outstanding performance is:
First, the temperature characteristics
Silicone products are silicon-oxygen (Si-O) bonds as the main chain structure, C-C bond bond energy of 82.6 kcal / mole, Si-O bond in the organic silicon for 121 kcal / Mole, so the thermal stability of silicone products, high temperature (or radiation exposure) molecular chemical bonds do not break, not decomposition. Silicone can not only high temperature, but also low temperature, can be used in a wide temperature range. Whether it is chemical or physical and mechanical properties, with the temperature changes are very small.
Silicone products are the main chain of -Si-O-, no double bond exists, it is not easy to be ultraviolet and ozone decomposition. Silicone has better thermal stability and resistance to radiation and weather resistance than other polymer materials. Silicone in the natural environment of the service life of up to several decades.
Third, the electrical insulation performance
Silicone products have good electrical insulation properties, the dielectric loss, withstand voltage, arc resistance, corrosion resistance, volume resistivity and surface resistance coefficient are among the best in the insulation materials, and their electrical performance by the temperature and frequency The impact is very small. Therefore, they are a stable electrical insulation material, is widely used in electronics, electrical industry. Silicone in addition to excellent heat resistance, but also has excellent water repellency, which is the use of electrical equipment in the wet conditions with high reliability protection.
Fourth, physical inertia
Polysiloxane compounds are one of the known inactive compounds. They are very resistant to biological aging, and animal body without rejection, and has a good anticoagulant performance.
Fifth, low surface tension and low surface energy
Silicone is very supple, its molecular force is much weaker than hydrocarbons, therefore, than the same molecular weight of the hydrocarbon viscosity is low, the surface tension is weak, the surface is small, film-forming ability.
At present, with the rise of the power LED in the application of lighting, the international manufacturers began to find power in China have the advantage of the manufacturers as partners, orders are relatively large, the power has begun to penetrate into the LED lights, LED bulbs, etc。
Field, follow-up will be more rapid development. Which power LED came to the TV application, the price of the past two years has been down, and customers on the luminous efficiency is an annual increase of 10% to 15%, so that the power of the LED to improve the cost, coupled with the power LED light source scattered benefits , Used in fluorescent tubes, bulb also has its advantages, to accelerate the penetration of the power LED. It can be seen that the medium power LED will become the mainstream of the bulb, then the future light bar gluing the application of plastic packaging in the proportion of the power bulb will increase.
