3, Main part introduction
The main part of Vacuum Chamber Potting machine comprize with glue tank , mixing system (screw pump),mixing /clean system , control system and so on .
3.1 Glue storage tank
As per glue feature and customer's process , glue should be preprocessing before metering3.1.1 We use stainless panel vacuum pressure tank which can bear negative pressure of inner glue tank .
3.1.2 The bottom of glue tank with heating system.
3.1.3 Tank with motor stirrer that prevent the glue from sediment and keep the glue in constant temperature.
3.1.4. Tank with high /low liquid sensor that ensure alarm warning when liquid higher or lower the setting level .
3.1.5. Tank with vacuum defoamation (defoamation time can be set through touch screen), so the material can be re-filled through vacuum negative pressure .
3.1.6.Tank with pressure releasing ball valve ; the bottom of tank reserved back flow connector and river closure ball valve.
3.1.7 Tank with artificial feeding mouth that can be added glue appropriately .
3.1.8. Tank with dry-filter can prevent glue from crystallization .
3.3 Fully automatic material mixing system (dynamic mixing)
3.3.1 dynamic glue mixing to assure glue mix evenly.
3.3.2 Glue touched parts with stainless design to aquired high material compatibility.
3.3.3 Glue valve with suck back function to prevent glue from dropping after cut off .
3.3.4 Rod shaft use original imported parts to maintain high durability.
3.3.5 Don't need to disassembly the mixing system to clean and save cleaning time .

AB component glue through suck back valve and come into mixing tube , like picture. The mixture finally be potting to products . When finished glue potting , the sucking valve can provent glue from dropping immediately to provent glue from dropping to other place.
3.4 Operation Controlling System .
3.4.1 Glue-out amount is pushed out by motor pushing rod metered by controlling the speed of pushing motor.
3.4.2 Adjustable glue-out synchronization , make sure A/B glue flow out of the valve at the same time gel resistance timmer to provent glue from curring .
3.4.3 The machine with gel preventer timmer,when time is arrived setting , the glue will discharge automatically and provent glue cure inside the mixing tube .
3.4.4 Can select signal glue-out quantity function and continuous gluing function to meet up with different processes requirement .
3.4.5 The whole controlling mode use Panasonic PLC control ,MGCS touch sreen devics.
3.4.6 Mornitoring the times of double liquid valve , vacuum pump , metering pumps and display on touch sreen .
3.4.7 E-Stop display the motor , dirver , pressure and with the warning system.
3.4.8 Configure secure interlock mechanism to prevent labor's wrong operation. The equipment grounding and likely to accumulate static charge of metal device , metal conductive objects are connected to ground , accord with GB50169-2006 <Electric device installation and acceptance specification for construction of grounding device> .
3.4.9 Can be communicatied with MES system .Fourth : Vacuum Chamber three axis glue potting machine
1,Vacuum Chamber
1.1 Configure security grating toughened glass , observation window, inlet and outlet with safety protection device , to ensure the safety of operators.
1.2 Digital display vacuum degree with time setting function , PLC communicate with glue mixing machine; can work automatically.2,Vacuum glue dispensing valve
2.1 Vacuum spcial glue valve used for glue potting and prevent glue from dropping .
2.2 Stainless steel design for glue touched parts , rod shaft sealing parts are use original import parts to keep high durability .
2.3 Vacuum valve can be washed via self-cleaning , to provent remained glue inside and caused blocking .3,Three axis working platform
3.1 Three axis chamber installed on the top , which is curtail the chamber volume effecially and accelerate vacuum speed .
3.2 Touch screen operation , English & Chinese operation version , can record and display different parameter .
3.3Program dot , line , arc , circle and some irregularity products . Glue potting files can be edit on programming or import from CAD. The program memory 99pcs . The touch sreen programming support the whole column , graphical browsing , group editing and other functions.3.4 Z axis fixed board can be adjusted up and down to adopt different workpieces on different heights , you don't re-edit the working path , but only adjust the working path when replace the nozzles .
