Provided is a system for supplying a photoresist. In an embodiment, a system for supplying a photoresist includes a pressure adjustment container provided to a supply line connected from a chemical liquid bottle to a first tank, and the pressure adjustment container includes a housing having a space formed therein, a separator separating the space of the housing into a first space and a second space, an inflow port making a photoresist flow in the first space, a discharge port discharging the photoresist from the first space, and a pressurized fluid inflow port supplying a pressurized fluid to the second space, and a volume of the first space varies depending on the supply of the pressurized fluid.

A retaining system for a solenoid assembly of a liquid adhesive dispensing system includes a quick-release mechanism configured to secure the solenoid assembly in place. The quick-release mechanism engages an air tube of the solenoid and thereby secures the entire solenoid assembly to a manifold. The quick-release mechanism can release the solenoid, facilitating easy removal of the entire solenoid assembly, by a simple turning, pushing, or pulling action on the quick-release mechanism. The released solenoid can then be removed and replaced, thereby minimizing downtime caused due to the replacement of a faulty solenoid.

The present disclosure provides a coating device including a first storage tank for storing a material to be coated, a needle cannula to which the first storage tank is connected by means of a corresponding first line, a gas output device for outputting a first pressurized gas from a gas source, including a first gas output line extending into the first storage tank, wherein the gas output device is capable of outputting the first pressurized gas to the first storage tank through the first gas output line such that the material to be coated stored in the first storage tank is discharged under a gas pressure and enters the needle cannula through the first line.

A method for controlling a recirculation pump assembly is disclosed. The method includes receiving a process-dependent characteristic and determining a recirculation flow rate of adhesive that flows to the recirculation pump assembly based on the process-dependent characteristic. The method further includes determining a recirculation pump speed of the recirculation pump assembly for pumping the adhesive to a supply channel using the recirculation flow rate, and adjusting an operating speed of the recirculation pump assembly to match the recirculation pump speed. A system and storage device for performing the above method are also disclosed.

An embodiment coating system for a secondary battery includes a supply tank connected to a slot-die and configured to store a slurry, an in-line viscometer configured to measure viscosity and temperature of the slurry, a flow meter configured to measure a flow rate of the slurry, a flow rate adjustment valve configured to adjust the flow rate according to a feedback signal based on the measured flow rate, a coating bead sensor configured to detect in real time a slurry coating bead shape discharged from the slot-die to a base material, and a coating controller configured to detect a process condition change event by monitoring a slurry property and the slurry coating bead shape in real time and to control the flow rate of the flow rate adjustment valve based on reference data corresponding to a changed slurry property.

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

An adhesive dispensing system for applying liquid adhesive to a substrate using different nozzles with the same manifold is disclosed. The adhesive dispensing system includes a manifold having a body, a first clamp configured to engage the body of the manifold, a second clamp configured to engage the body of the manifold, and a nozzle. The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.

Fluid applicators with precise volume dispensing control for dispensing fluids such as a disinfectant in a controlled manner are described herein. Such fluid applicators may include a barrel including a sidewall having an inside surface defining a chamber for retaining a fluid, an end press, a push rod disposed within the chamber, the push rod having a push button and a piercing tip, a cap attached to a port via a hinge to cover a hydrophobic filter disposed on the sidewall of the chamber, a one-way valve disposed on the outlet on a distal end of the barrel, a disinfectant disposed within the chamber; a housing having a base and an open proximal end; and a fluid applicator sponge disposed in the base of the housing. An alternate fluid may include a deformable end press, a plurality of volume scale markings on an outer surface of the barrel, a push rod, a one-way valve and applicator sponge.

This intermittent coating device is provided with a die which applies paint to a workpiece, and a first intermittent valve and a second intermittent valve which can switch between a first state in which paint is provided to the die and a second state in which provision of paint is stopped. The first intermittent valve and the second intermittent valve have mutually different timing for switching between the first state and the second state.

An intermittent valve device includes: an intermittent valve capable of switching between a first state in which a coating material is supplied to a die that applies the coating material onto a material to be coated and a second state in which the supply of the coating material is stopped; and a drive unit that switches the first state and the second state of the intermittent valve. The drive unit includes a cam that rotates in one direction with a circumferential surface of the cam connected to the intermittent valve. The cam includes, on the circumferential surface, a first shape part that places the intermittent valve in the first state, and a second shape part that places the intermittent valve in the second state.
