Application of zirconia ceramic nozzle in dispensing machine
The ceramic nozzle of the dispenser is to point a special adhesive in advance on the position of the patch needed on the PCB board to fix the patch element and then go through wave soldering after curing.Dispensing is carried out automatically according to the program, and its working principle adopts the form of pneumatic auxiliary dispensing valve control.The applied industries mainly include electronic industry, lighting industry, home appliance industry and other fields. The operation form of automation improves the production efficiency and product quality.
Dispenser nozzle classification industry on the glue control equipment called a lot of, dispenser nozzle, dispenser, dispenser, dispenser, dispenser, dispenser and so on.Based on our company's cognition of the industry and years of industry experience, and referring to the summary of the industry in Europe, the United States and Japan, this kind of equipment is summarized as dispenser nozzle and divided into three or two categories:
一、 a single component dispenser nozzle
Dispensing controller;Desktop dispenser nozzle;Floor dispenser nozzle.
二、 two-component dispenser nozzle
Semi-automatic two-component dispenser nozzle;Automatic two-component dispenser nozzle.
Three, non-standard dispenser nozzle
Ordinary
1. Nozzle of controller dispenser
Including automatic dispenser nozzle, quantitative dispenser nozzle, semi-automatic dispenser nozzle, digital dispenser nozzle, precision dispenser nozzle.
2, desktop dispenser nozzle
Including desktop dispensing machine nozzle, desktop triaxial dispensing machine nozzle, desktop four axis point glue machine nozzle, or desktop type automatic dispensing machine nozzle, the axle assembly line dispensing machine nozzle, long nozzle glue, glue dispensing machine nozzle, draw more dots glue machine nozzle, turn marks glue machine nozzle, horn glue dispensing nozzle, cell phone buttons machine nozzle, cabinet dispensing machine nozzle, etc.
3, semi-automatic dispenser nozzle
Including microcomputer precision dispenser nozzle, LED digital display dispenser nozzle, automatic suction dispenser nozzle, code extraction cycle dispenser nozzle.
Automatic type
1. Floor type two-liquid dispenser nozzle.
2. Spray nozzle of automatic dispensing machine (this dispensing machine adopts spray valve, online operation, mainly used for PCB board three-paint spraying, playing the role of dustproof, moisture-proof and insulation).
3, conductive adhesive automatic dispenser nozzle (this dispenser nozzle and ordinary dispenser nozzle is different in that the point out of the conductive adhesive section is triangular distribution state, mainly used for electromagnetic shielding dispenser).
4. Phosphor injection dispenser nozzle (this dispenser nozzle is mainly used in LED industry).
Dual Y axis
This type of dispensing machine nozzle includes two motion platforms, the traditional dispensing machine nozzle generally contains only one moving platform. Each moving platform can generally be equipped with more than 5 point glue head, to achieve the dispensing efficiency leap-forward promotion.Suitable for LCD, LCD module precision dispensing, in the mobile phone LCD screen, PDA and other LCD screen applications are the most widely used.
Non-standard classes
In accordance with certain special requirements of customer product process, custom-made, such dispensing machine nozzles are often more expensive to develop.
UV dispenser nozzle
1、UltimusV dispenser nozzle introduction:
Instead of operator guesswork, pressure and microprocessor-based timing devices are used to regulate the amount of fluid applied to the components.EFD pneumatic dispensing system eliminates the variability of traditional dispensing process.
2、UltimusV dispenser nozzle advantages include:
High productivity and pass rate.Strong process control.Excellent product quality, reliability and elegant appearance.
Lower rework rate and less defective rate.No waste or confusion.Training has been simplified for new staff.
UltimusV high precision dispenser nozzle improves the accuracy and consistency of dispensing effect to a new level. It also enables accurate control of adhesives with easy viscosity, such as:
A two-component epoxy adhesive whose viscosity varies with time.Viscosity due to temperature changes in the UV curing adhesive, etc.
3、UltimusV dispenser nozzle characteristics and advantages:
1. whether the viscosity of adhesive changes or not, the adhesive point is always constant.
2. Electronic control of dispensing time, air pressure and vacuum ensures highly accurate dispensing effect.
3. Programmed control of air pressure can be automatically adjusted with the change of fluid viscosity.
4. The unique "setitandforgetit" technology makes the dispensing operation easier, each fluid dispensing only needs to be programmed once.
5. All dispensing parameters are displayed at the same time, and the process control is greatly simplified.
LED dispenser nozzle
LED special equipment, dedicated to the white LED production process of phosphor powder dispensing.At present, the nozzle of LED dispenser can be roughly divided into two categories: one is pneumatic, the other is metering.
Due to the LED phosphor glue amount requirements are very accurate, and the pressure type will vary with the pressure size, the amount of glue will change greatly, so the pressure type dispenser nozzle can not hide the needs of the LED industry, so it is not called LED dispenser nozzle.LED industry is basically used in the measurement type, the amount of precision of his glue can be up to 1/10000, can meet the LED phosphor powder dispensing glue, this is called the real LED dispensing machine nozzle.
