Systems and methods for the injection/dispensing of fluid material in a volumetrically accurate and repeatable manner via an injection cell that interconnects two reservoirs of the fluid material. The injection cell has a normally closed dispensing valve that is opened for dispensing of the fluid material during a compression cycle, and closed during a return cycle. Opening and closing of the dispensing valve is effected using either or both of pressurized air and/or a motorized linkage. During the compression cycle, independent longitudinal displacements of a piston cylinder and a piston within the injection cell act to first open the dispensing valve and subsequently eject fluid material within the piston cylinder via the opened dispensing valve. The piston cylinder and piston are returned to an initial state that facilitates reloading of the injection cell from the reservoirs and closes the dispensing valve during a return cycle.

A dispenser used for discharging a mixture of gas and a paste material includes: a nozzle part provided in a tip end part of a body and having a tip end opening through which the mixture is discharged; a flow path extending from a mixture introduction part to the tip end opening through a hollow space of the nozzle part; a needle part movable in the flow path of the nozzle part to open and close the flow path; a driving part that drives the needle part; and a stopper part that limits an operation range of the needle part. The nozzle part has a tapered section in which an inside diameter of the flow path of the nozzle part decreases toward the tip end opening. Also provided is a stopper position adjusting part that adjusts a stop position defined by the stopper part.

A glue dispenser dispensing switch includes a switching device main body, a needle holding base, a wear-resistant plate, and a rotating device. The switching device main body is equipped with a double liquid inlet, the needle holding base is equipped with a mixed glue outlet, the wear-resistant plate is installed between the switching device main body and the needle holding base, and the wear-resistant plate is equipped with a wear-resistant plate opening. The rotating device is utilized to rotate the needle holding base or the wear-resistant plate. A mixed double-liquid glue passes through the double liquid inlet, the wear-resistant plate opening and the glue outlet to dispense a mixed glue while the double liquid inlet, the wear-resistant plate opening and the glue outlet are overlapped. In addition, a double liquid dispensing equipment is also disclosed herein.

A casing of an aircraft turbomachine includes an annular shell extending around an axis A and made of a composite material having fibers that which are woven and embedded in a resin. An annular layer made of abradable material extends inside the shell, around axis A and is obtained by spreading and polymerizing a paste. Support panels extend around axis A and are interposed between the shell and the abradable layer.

An adhesive dispenser includes a support structure, a valve body that is mounted to the support structure and is configured to receive at least first and second adhesive materials, and a nozzle assembly that is connected to the valve body. The nozzle assembly includes a rigid tube that extends from the valve body to a tube end, and a mixing insert that is received within the tube and extends to an insert end. The mixing insert is configured to receive the first and second adhesive materials from the valve body for intermixing upstream from the insert end. The dispenser further includes a nozzle that is supported relative to the support structure and arranged about the tube end and the insert end. The nozzle has an opening at a terminal end, and a shaped aperture adjoins the opening. The nozzle is configured to dispense intermixed adhesive through the opening and aperture onto a component.

A co-axial roller printing equipment includes a working platform, a roller, a grinding device, a cutting device and a coating structure. The working platform is configured for carrying a substrate and driving the substrate to move. The roller is disposed above the working platform and has a surface. The grinding device is disposed on the working platform and configured to contact and grind the surface of the roller. The cutting device is disposed on the working platform and configured to cut the surface of the roller to form a plurality of relief structure. The coating structure is configured to receive a slurry and coat the slurry on the relief structures. Wherein, the grinding device and the cutting device grind and cut the surface of the roller in sequence; wherein, the coating structure coats the slurry on the relief structures, then the roller prints the slurry on the substrate.

A robot end effector for dispensing an extrudable substance comprises a chassis and cartridge bays, attached to the chassis and each shaped to receive a corresponding one of two-part cartridges. Robot end effector also comprises a dispensing valve, attached to the chassis and comprising a valve inlet and a valve outlet, in selective fluidic communication with the valve inlet. Robot end effector further comprises a manifold, comprising a manifold outlet and manifold inlets. The manifold outlet is in fluidic communication with the valve inlet. Robot end effector additionally comprises a plunger assembly, comprising pairs of plungers. Plunger assembly is arranged to concurrently extrude contents of the two-part cartridges through the cartridge outlets when the two-part cartridges are received by the cartridge bays. Robot end effector also comprises a non-rotating linear pneumatic actuator, configured to selectively move the plunger assembly relative to the chassis.

A modular fluid application device (10) includes a module base (12) and first and second fluid passageways extending within the module base and intersecting to form a nozzle fluid supply passageway. The modular fluid application device also includes a fluid outlet (22) formed on a nozzle mounting surface (24) of the module base fluidically connected to the nozzle fluid supply passageway, a base air passageway extending in the module base and an air outlet formed on the nozzle mounting surface fluidically connected to the base air passageway. A first module bank (14) is removably mounted on the module base and includes at least one first module having a first valve configured to control a flow of fluid in the first fluid passageway. A second module bank (18) is removably mounted on the module base and includes at least one second module having a second valve configured to control a flow of fluid in the second fluid passageway. The first module and the second module are mounted at an angle relative to one another.

A Robotic Coating System with Real-Time Mixing has a particular arrangement of a robotic gantry, two peristaltic pumps, a mixer, a hollow brush, two tanks, and a computerized controller. The invention has tubes providing fluid communication from a coating tank and a thinner tank through the pumps and mixer to the brush. The invention provides everything necessary for robotic coating in one compact system. This invention provides the ability to apply coatings to an item, without pre-mixing the coating components. A computerized controller drives the brush through a pre-programmed path to coat required areas and not coat sensitive areas. The System operates upon utility service, typically 110 VAC, and it also self-cleans.

An electrode coating system includes a slurry storage tank in which a slurry is stored, a coating slot die configured to receive the slurry, and a line through which the slurry flows from the slurry storage tank to the coating slot die, in which the line includes a first line and a second line, and the slurry is configured to flow from the slurry storage tank to the coating slot die selectively through the first line or the second line.
