Definition of liquid nitrogen automatic dispensing system

The uses of liquid nitrogen automatic dispensing are divided into filling, dripping, bonding, perfusion, coating, and sealing, so liquid nitrogen automatic dispensing is also known as automatic glue filling machine, automatic glue applicator, automatic glue machine, automatic glue injection machine, Automatic glue dispenser, etc., is an automatic machine that specially controls the fluid and drips, coats and pots the fluid on the surface of the product or inside the product. The automatic dispensing machine is mainly used for bonding, pouring, coating, sealing, filling, dripping, linear/arc/circular gluing, etc. of glue, oil and other liquids in the product process.

Liquids suitable for liquid nitrogen automatic dispensing: various glues, liquids, oils, etc., including silicone, EMI conductive glue, UV glue, AB glue, quick-drying glue, epoxy glue, sealant, hot glue, grease, Silver glue, red glue, solder paste, thermal paste, solder mask, clear paint, screw fixer, etc.

Application field of liquid nitrogen automatic dispensing: automatic dispensing machine is suitable for various fields of industrial production: buttons, printing, switches, connectors, computers, digital products, digital cameras, MP3, MP4, electronic toys, speakers, buzzers , Electronic components, integrated circuits, circuit boards, LCD screens, relays, speakers, crystal components, LED lights, chassis bonding, optical lenses, mechanical parts sealing.

At present, single-liquid liquid nitrogen automatic dispensing has been done very maturely. The world brands are mainly EFD dispensers and Musashi dispensers, Feishi can dispensers, IEI dispensers, etc., which can achieve high precision, but the price relatively high. Domestic automatic dispensing machines are more cost-effective. Because the two-component glue dispenser uses a metering pump to measure the volume ratio, the price is very high whether it is an imported brand or a domestic one. The above is the definition of liquid nitrogen automatic dispensing system.

Classification of liquid nitrogen automatic dispensing

Single-liquid liquid nitrogen automatic dispensing (also known as single-component dispenser)

Syringe type liquid nitrogen automatic dispensing: suitable for small dose manual dispensing;

Quick-drying glue liquid nitrogen automatic dispensing: suitable for anaerobic quick-drying glue similar to 502;

Desktop liquid nitrogen automatic dispensing: program control, automatic design of dispensing schedule, suitable for automatic program control; including desktop three-axis liquid nitrogen automatic dispensing, desktop four-axis liquid nitrogen automatic dispensing, round liquid nitrogen automatic dispensing, etc.

Pressure barrel type liquid nitrogen automatic dispensing: suitable for large-dose precision dispensing, and the glue must have a certain fluidity;

Pressure barrel + automatic dispensing valve + liquid nitrogen automatic dispensing controller

Two-component liquid nitrogen automatic dispensing (also known as two-component liquid nitrogen automatic dispensing, two-component liquid nitrogen automatic dispensing, AB glue liquid nitrogen automatic dispensing, two-component glue dispenser, two-component glue dispenser, two-component glue dispenser Glue filling machine, AB glue filling machine, double-group glue filling machine, two-component glue filling machine, double-liquid glue filling machine, AB glue filling machine, etc.) The above is the classification of liquid nitrogen automatic dispensing

Selection principle of liquid nitrogen automatic dispensing

Glue: One-component dispenser for ordinary glue, two-component liquid nitrogen automatic dispensing for AB glue, and liquid nitrogen automatic dispensing for quick-drying glue.

Dispensing process: semi-automatic dispensing machine (such as foot control) is used for ordinary dispensing, and desktop, three-axis, circle drawing, etc. with automatic function liquid nitrogen automatic dispensing are used for precise position marking.

The automatic function of liquid nitrogen automatic dispensing is actually an auxiliary function. The glue dispenser plays the role of controlling the glue, and other functions can be realized with the help of an automatic manipulator.

Work efficiency and environment: There are few products, and manual glue is used when efficiency and dispensing accuracy are not pursued. It is required to precisely control the contest and use the machine. If automated dispensing is required, use a machine with automated functions.

Cost: There are various dispensing options, not all dispensing requires the use of a machine, and not all automated dispensing must be attached to liquid nitrogen automatic dispensing. Considering the cost, if a certain glue needs to be used in a too expensive machine, you can consider replacing the glue. If the price of a dispenser with automation is too high, consider moving the product instead of the dispense head. The above is the selection principle of liquid nitrogen automatic dispensing.
