A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.

In manufacturing a laminated iron core by laminating and bonding iron core laminates blanked from a sheet steel strip into a prescribed profile, the adhesive agent can be applied to the iron core laminates in a stable manner without regard to the arrangement and the number of the application spots on each iron core laminate.

The casing is provided with a plurality of ejection orifices (H1 to H3) each communicating with a corresponding one of the adhesive agent storage chambers and configured to eject the adhesive agent.

A multi-row melt-blown fiber spinneret (8) enables stacking rows (12.sub.1, 12.sub.2, 12.sub.3) of polymer outlet orifices (36) more closely together than is achievable with conventional melt-blown fiber spinnerets. The fiber spinneret configuration also enables dense side-by-side packing of the polymer outlet orifices. The fiber spinneret is configured so that air knife channels (14.sub.1c, 14.sub.2c, 14.sub.3c, 14.sub.4c) and individual intricate small air knife passage feeds, together with their associated melt flow channels (50.sub.1, 50.sub.2, 50.sub.3), are formed in the same body member. The rows of polymer outlet orifices are supplied with a polymer melt by a single polymer inlet (20), which delivers the polymer melt to the individual polymer melt flow channels. The air knife channels are directed through the body member, in which the polymer melt flow channels are formed by islands and air flow passage feeds. The body member is constructed by operation of a 3D printer for direct metal printing.

Disclosed are a substrate treating apparatus and a substrate treating method.

According to an embodiment of the inventive concept, the purge operation of the purge nozzle is performed while the nozzle arm is moved from the first substrate support member to the second substrate support member, it hardly influences the operation of treating the substrate while the nozzle arm is moved from the first substrate support member to the second substrate support member. According to an embodiment of the inventive concept, the substrate treating apparatus may perform an operation of purging the photosensitive liquid nozzle while the treatment liquid supply unit performs a process of supplying the photosensitive liquid to the substrate. Accordingly, because the operation of purging the photosensitive liquid nozzle is performed at the same time when the substrate treating apparatus performs a process, productivity may be improved.

An adhesive dispenser is includes a plurality of adhesive dispensing parts, each including an adhesive dispensing tube, an adhesive extrusion assembly, and a driving component. The adhesive dispensing tube is configured to carry an adhesive therein. The adhesive extrusion assembly is connected with the adhesive dispensing tube, and is configured to apply a pressure to the adhesive in the adhesive dispensing tube such that the adhesive is dispensed from the adhesive dispensing tube. The driving component is configured to drive adhesive extrusion assemblies of the plurality of adhesive dispensing parts to apply the pressure to the adhesive.

Disclosed is a hub paint spraying equipment equipped with a spraying robot having a combined spray gun, comprising a control system, a wheel type recognition system, a brace recognition system, a paint supply device, a quick color changing device, spraying robot, combined spray gun, a cleaning system, a conveying chain and an accessory device. Combined spray gun installed at the end of spraying robot of system is formed by assembling a plurality of spray gun individuals, spraying process and parameter are automatically called by automatic recognition of wheel type recognition system, category of a colored paint is automatically changed, spraying parameter and robot spraying path program are called, and mixed-line intelligent spraying of a hub is realized, so that problems of low utilization rate of equipment due to consumption of a lot of time for replacing colored paint and excessive in-process caused by classification and temporary storage stacking are avoided.

A method for pumping, tracking, and controlling a fluid includes the steps of producing a drive signal for driving a motor of a pump using a controller, driving the motor to pump a fluid based on the drive signal, sending a dispense signal from the controller to a sprayer for dispensing the fluid, determining a work piece count as a function of a work piece signal provided to the controller from the work piece sensor, detecting the position of a rod connected to the motor and the pump using a position sensor, creating a position signal as a function of the position of the rod using the position sensor, sending the position signal to the controller, and determining a volume usage as a function of the position of the rod using the controller.

A fluid application system includes a pair of identical, spaced apart, fluid applicators that each include a fluid permeable pad saturated with fluid. In one implementation, each applicator includes a pair of conduits coupled to a base plate, wherein each conduit includes a slot configured to receive an end of the pad. In another embodiment, each applicator defines a reservoir between adjacent plates and channels fluid from the reservoir though openings in the plate to the pad. In another implementation, each of the applicators includes a base plate, a conduit coupled to the base plate, and a housing slidably coupled to the base plate. The housing includes a plurality of pads and is moveable to selectively prevent fluid flow between the conduit and the pads in a first position or to couple the pads in fluid communication with the conduit in the second position.
