TH27223B - Positive-displacement electronic fluid dispenser - Google Patents

Abstract

Systems and methods of supplying fluids are used in most industrial environments. For the dispensing of fluids such as epoxy, silicones, and other adhesives with flow volume control. Fluid The system consists of an ergonomically designed handheld dispenser. More appropriately with a sprayer Commonly used designs are included. In which the dispenser was connected by a cable Electric to the electronic control unit And the dispenser is equipped with a step motor that drives the piston. The displacement of the piston or threaded device generates positive pressure in response to the electronic signal produced by the control unit and the displacement of the piston or threaded device. Depending on the fluid contained in the syringe Which causes fluid to be injected from the syringe

Claims (8)

1.Positive-displacement electronic fluid distribution system Which includes Electronic control unit that can be selected as a pre-programmed configuration. Or variable assignments, control cables, and ergonomic hand held dispensers with finger-operated switches where the ergonomic hand-held dispensers are attached to the electronic control unit. Blackout by Control line and by which the ergonomic hand-held dispenser Will have the ability to respond Traditional syringe and plunger kit, and with the ergonomically organized hand dispenser Equipped with a motor that replaces the drive shaft, to be positioned within the traditional cylinder and piston assembly, a specific distance responds to the electronic drive signal generated by the rear control unit. The finger-operated switch is pressed by the user. 2.Positive fluid distribution system - Electronic displacement, as requested In claim 1, where the electronic control unit has a built-in power source 3.Positive-displacement-electronic fluid distribution system , As requested to hold the right In claim 1, where the electronic control unit has an electric wire that may draw power from one of the Is from energy storage devices or from reducing transformers to convert household current to Suitable current to drive a stepper motor 4.Positive fluid distribution system - Electronic displacement, as requested In claim 1, where the drive shaft is fixed to the dispersion plate, which secures the piston in the syringe set and Traditional piston 5. A method of extruding the volume of fluid from a passive-displacement electronic fluid dispensing system, which is equipped with an electronic control unit capable of Selectable in the form of pre-programmed or variable assignment, control cable, and ergonomic hand held dispenser with finger-tapped switch. The ergonomic hand held is attached to the electronic control unit by the control line and by the type dispenser. Hand-held ergonomic It will have the capability of responding to traditional set of sprayer and piston And by the way, the ergonomic hand held dispenser is provided with a motor that replaces the drive shaft, positioned within the traditional sprayer and piston assembly. , Specific distance responds with The electronic drive signal is generated by the control unit after the finger-operated switch is pressed, whose trajectory is combined with the steps of a) the selection on the desired fluid volume control unit to be B) Positioning the ergonomic hand-held dispenser so that the fluid is dispensed as needed. C) Finger-operated switch press on the ergonomic hand held dispenser to birth An electronic drive signal from the control unit to the motor that drives the piston for a specified distance so that Will accurately roll the volume of the desired fluid Where the removal of the drive shaft is attached to the piston in the traditional syringe and piston assembly. It creates positive pressure on the fluid that is loaded in the syringe, thus resulting in volume rolling. That the fluid from the syringe 6.A method for extruding a precise volume of a fluid from a fluid dosing system. Possible - electronic displacement as requested in Clause 5, where the control unit Electronics have a built-in power source. 7.Method of extruding a precise volume of a fluid from a fluid dosing system. Possible - electronic displacement as requested in Clause 5, where the control unit Electronics have electrical cables that may draw power either from energy storage devices or from A reduction transformer to convert the domestic current to a suitable current to drive stepper motors. 8. Method for extruding volume of fluid from a fluid dispensing system. Possible - electronic displacement, as requested in Clause 5, with the drive shaft fixed. With the distribution plate, which is attached to the piston in the traditional syringe and piston assembly
