Abstract:
An application head for dispensing a flowable medium includes a nozzle chamber in the application head and a nozzle needle movably mounted in the nozzle chamber. A supply channel and a supply line introduce the medium into the nozzle chamber. A drive moves the movable element. A lever arm is movably fastened to the nozzle needle and connected to the drive. The lever arm extends through a membrane of a membrane suspension connect the lever arm movably to the application head and form a seal to prevent escape of the flowable medium. Alternatively, a rocker suspension has a lever arm connectable to the movable element and the drive, a plate element has an opening through which the lever arm extends, a rocker mounting device connects the lever arm movably to the application head and a sealing device prevents any escape of adhesive from the chamber through the plate element opening.
Abstract:
A continuous process for preparing a pressure sensitive adhesive using a planetary roller extruder is described. The continuous process includes introducing at least one non-thermoplastic elastomer into a planetary roller extruder and initially compounding the non-thermoplastic elastomer in the planetary roller extruder to form an initially masticated non-thermoplastic elastomer. Then, a solid raw material, a liquid material, or both are introduced into the initially masticated non-thermoplastic elastomer in the planetary roller extruder, and subsequent compounding of the initially masticated non-thermoplastic elastomer with these additional components occurs to form an adhesive composition.
Abstract:
A hot melt adhesive metering pump assembly, and an integral reservoir tank fluidically connected thereto and the hot melt adhesive metering pump assembly comprises a plurality of rotary, gear-type metering pumps which are arranged in a compact, longitudinally spaced manner upon a drive gear manifold. All of the driven gears of pumps are respectively driven by manifold pump drive gears which are rotatably mounted upon a common motor-driven rotary drive shaft rotatably disposed within the drive gear manifold, and a first side wall member of a base portion of the reservoir tank is integrally connected to a side wall portion of the drive gear manifold, while a second side wall member of the base portion of the reservoir tank is provided with a plurality of hose connections to which hot melt adhesive delivery hoses are to be connected so as to respectively convey the precisely metered amounts of the hot melt adhesive material toward the applicator heads.
Abstract:
A moveable dispenser assembly including is shown. The dispenser includes a reservoir having bonding adhesive therein including particles and a liquid carrier. The dispenser is moved to provide agitation to the dispenser for mixing the bonding adhesive into a homogeneous mixture of particles and the liquid carrier. An opening at an end of said dispenser dispenses the bonding adhesive onto a bonding location on the workpiece without removing the dispenser from the die attach apparatus. A one controller for sends a control signal that triggers moving of said moveable dispenser assembly for mixing said bonding adhesive before dispensing said volume of bonding adhesive onto said surface of said workpiece. The controller includes logic to control of movements such as oscillations to keep the bonding adhesive well mixed based on a comparing a parameter to be in a predetermined limit or range.
Abstract:
A hand-held vessel has a bottom wall, a sidewall and a supportive strap attached to the bottom wall and the sidewall. The bottom wall and sidewall have an inner and outer surface. The sidewall extends from the bottom wall, whereby the inner surfaces of the bottom wall and sidewall define a cavity for holding fluids or loose materials therein. The strap has a first end and a second end, whereby the first end is fixedly attached to the sidewall and the second end is selectively secured to the bottom wall. The strap is adaptable to accept a user's hand disposed between the strap and the outer surface of the sidewall. The strap urges the hand against the outer surface of the sidewall to secure the vessel to the hand and stabilize the vessel with respect to movement relative to the hand.
Abstract:
A material pressure feeding apparatus 10 includes a container 12 for receiving a bag 11, in which a viscous material M is contained, a press member 13 exerting a pressing force on the material, a pressure feeder 15 pressure-feeding, to the outside, the material M sucked by the pressing force by the press member 13, and an annular member 16 positioned on the outer peripheral side of the press member 13. The press member 13 has a supporting space S on the outer peripheral side thereof, and a ring portion 40 constituting an annular member 16 is supported in the supporting space S in a relatively movable state. Thus, even when the press member 13 is inclined, the annular member 16 is configured so as not to form a clearance between it and the inner peripheral surface of the container 12 without any influence of the inclination.
Abstract:
A slurry distributor for use in a continuous manufacturing process includes an inlet opening and a shaped duct adapted to receive a flow of slurry provided at the inlet opening. The shaped duct has a parabolic guide surface adapted to redirect the flow of slurry. An outlet opening in fluid communication with the shaped duct is adapted to discharge the flow of slurry from the slurry distributor.
Abstract:
A fluid dispensing system includes a dispensing pump for delivering the fluid material to a substrate. The fluid dispensing system further includes a vacuum unit that draws a vacuum on the feed tube for removing gas impurities from the fluid material.
Abstract:
A semiconductor manufacturing apparatus comprises a discharge portion discharging a coating liquid onto a substrate; a gas supply tube supplying an inert gas into a liquid container that contains the coating liquid, and pressurizing an interior of the liquid container; a coating liquid supply tube airtightly supplying the coating liquid from the liquid container to the discharge portion using pressurization from the gas supply tube; a first connecting portion capable of attaching and detaching the liquid container to and from the coating liquid supply tube; a second connecting portion capable of attaching and detaching the liquid container to and from the gas supply tube; and a solvent supply tube supplying a solvent, which can dissolve the coating liquid, to the first connecting portion.
Abstract:
Provided is an ejection amount correction method and an applying apparatus, which can correctly measure the amount of an applied droplet and accurately correct the ejection amount. In an ejection amount correction method for measuring the amount of a liquid material ejected from a nozzle and correcting the ejection amount of the liquid material, a mirror is set near an application target surface at a predetermined angle with respect to the application target surface, an image of a droplet formed on the application target surface is picked up from a side through the mirror, the volume of the droplet is calculated based on the picked-up image of the droplet, and the ejection amount is corrected based on the calculated volume. An apparatus for carrying out the method is also provided.
