The history of dispenser development originally originated in the United States and Europe, with the large-scale demand for dispensers in the Japanese electronics industry, so the Japanese dispenser manufacturers of modern American dispensing machines were produced.
With the widespread application of glue abroad (including the United States, Japan, and South Korea), the demand for dispensing equipment is more extensive and diverse. A variety of dispensing machines, filling machines, and automatic dispensing machines have emerged in the market.
The development of China's industry has attracted a large number of Japanese and Taiwanese enterprises, and professional dispensing manufacturers have also poured into China. EFD in the United States, Musashi in Japan, etc., as well as Taiwan's independent dispensing machines, form a three-legged situation.
The beginning of China's dispensing machine is from 05-07, and China's private dispensing manufacturers began to rise. At first, it was an agent + independent research and development, or a manufacturer in the automation industry involved in the dispenser industry, and gradually developed into a manufacturer specializing in dispensing machines. At the end of 09, according to incomplete statistics, there are more than 30 professional manufacturers of domestic dispensing machines, including other non-professional automation or glue manufacturers, foreign dispensing manufacturers, distributors, etc., so many reach more than thousand.
At present, the development of China's dispensing industry is as follows: the single-component dispensing technology is relatively mature, and its development direction is automation and high precision. Domestic dispensing machines generally have low accuracy and insufficient stability. In the area of automated dispensers, domestic three-axis platforms, circular dispensers, etc. have a history of development for many years, if it is just ordinary precision, then the use of domestic dispensers and platforms is enough.
Two-component dispensing technology is in the exploration stage and is the development direction of the dispensing and filling industry. There is still a big gap in the current dual-liquid machine technology in China, and the product quality needs to be further improved. With the increasing use of AB glue, the requirements for filling and other processes will also be higher, and dual-liquid dispensers are another promising development area in the dispenser industry.
The generation of automatic dispensing machines can be traced back to the sixties, in the case of plastic bottle extrusion, manual dispensing and even toothpick dispensing, so that many industries that need to dispense produce huge defective products, resulting in batches of irreparable order losses, so in the sixties, manual dispensing machines were born, and with the development of automation technology, manual dispensing machines have been far from meeting the needs of industry, in the early eighties, automatic dispensing machines came out. Technology is the primary productive force, and the advent of automatic dispensing machines has played a great role in promoting industrial demand.
1. The brands of dispensing machines on the market at present:
USA: EFD
Japan: JANOME, IEI, Musashi
Germany: Scheugenpflug
South Korea: Taeha
Domestic: olks, Zhicheng, TENSUN, Ximeng, Shichun, Tianhao, Axis Control, DXN, Changli, Zhongchuangxin, Xinyinda, Daheng, etc.
Shenzhen Micropoint Fluid Technology Co., Ltd. focuses on the production of precision screw valves and jet valves, which can completely replace imported products in terms of performance, specific product information can be consulted 0755-21039793, Manager Zhou 18126381741.
However, international brands are not a little more expensive than domestic ones. If you don't have such strict requirements for accuracy, it is recommended that you buy domestic ones. Domestic single-component dispensers have done a good job in versatility, and the technology of ordinary controllers and automation equipment is relatively mature, as long as the precision requirements are so high, it can basically meet your requirements.
2. Benchtop dispensers are suitable for:
Relays, FPC boards, LCDs, LEDs, crystal oscillators, computer shells, optical drives, printers, ink clips, DVDs, digital cameras, switches, connectors, heat sinks, semiconductors and other electronic industries, or connected with SMT equipment for quick dotting/gluing, clocks, toys, medical equipment, semiconductors, mobile phone shells, notebook shells, transformers, mobile phone buttons, etc.
3. Desktop dispensers are suitable for glue
UV glue, AB glue, EPOXY (vinyl), white glue, EMI conductive glue, SILICON, epoxy resin, instant glue, silver glue, red glue, solder paste, heat dissipation paste, solder paste, clear paint, lubricating oil, screw fixing agent....... and other liquid dispensing.
4. Principles of common glue and needle use:
1. Four guidelines: small point - small needle, low pressure, short time
Large point - large needle, greater pressure, longer time
Thick rubber - oblique needle, large pressure, set time as needed
Water-based liquid – small needle, low pressure, set time as needed
2. Requires specially set fluids
Instant glue: Use a safety piston and Teflon lined metal needle for water-based instant glue, use a tapered oblique needle for thick instant glue, and use a PP needle if flexible.
UV glue: use amber syringe barrel, white piston and oblique needle (can block ultraviolet rays).
Light-curing adhesive: uses a black opaque syringe barrel, a white piston, and a needle that can block ultraviolet rays.
Anaerobic glue: Use 10CC syringe barrel and white PE universal piston.
Sealant and paste fluid: If the white piston rebounds is severe, please use the safety live type and use the oblique needle.
