System and methods for calibrating a coating system are disclosed. Initially, a material is dispensed using an applicator of the coating system for a predetermined time period. A characteristic of the dispensing of the material for the predetermined time period is then determined. The characteristic of the dispensing of the material is compared to a predetermined range and it is determined that the characteristic of the dispensing of the material is outside of the predetermined range. In response, a velocity of the applicator, a pulse rate of the applicator, a temperature of the material, a pressure of the material supplied to the applicator, or a fan width of the applicator is adjusted to change the characteristic of the dispensing of the material.

A hot melt dispensing system is described. The hot melt dispensing system includes a melter that melts solid material into hot melt, a pump that pumps the hot melt from the melter to at least one applicator, and a pressure control system that controls a pressure of pressurized air for operating the pump. The pressure control system includes a regulator assembly that controls the pressure of the pressurized air, and a drive component that actuates the regulator assembly. The hot melt dispensing system also includes a controller that determines a pressure setting for the pressurized air. The drive component receives the pressure setting from the controller and actuates the regulator assembly to a position associated with the pressure setting.

To provide a coating device which can precisely adjust a discharge amount of high-viscosity material. The coating device coats a high-viscosity material onto a workpiece, and includes a coating gun (2) which discharges the high-viscosity material having flowed in from an inlet port (211) from a discharge port (251); a supply mechanism which pushes out the high-viscosity material to supply from an injection nozzle; and a supply tube which connects the inlet port (211) and supply port. The coating gun (2) includes, at a gun flow channel (3a) from the inlet port (211) until the discharge port (251), a gear pump (31) and needle valve (26) as a discharge amount adjustment mechanism which adjusts the discharge amount of the high-viscosity material from the discharge port (251).

A flow detector for monitoring an adhesive flow in an adhesive applicator includes a sensor device arranged in the adhesive flow. The sensor device is formed as a capacitive sensor.

A sealing system for applying resin to a cut edge of a composite structure, the cut edge having exposed carbon fibers. The system includes: a tool that comprises a nozzle and a resin source; a controller configured to control: a movement of the tool, and flow of resin from the resin source to the nozzle; and an application tip connected to the nozzle of the tool and configured to apply the resin to the cut edge of the composite structure. The application tip may have an exterior surface with a circular cross section and an indentation for a first length along a longitudinal axis of the application tip and a first end and a second end configured such that a resin flows from the first end to the second end.

A sealant discharging apparatus includes a sealing gun, a movement controller, a discharge controller, a measuring instrument, and an air bubble detector. The sealing gun is configured to discharge sealant to an object. The movement controller is configured to cause the sealing gun and the object to move relatively. The discharge controller is configured to control a discharge amount of the sealant discharged from the sealing gun. The measuring instrument is configured to measure a distance to a sealant pool that has been discharged from the sealing gun and yet to be used to seal the object. The air bubble detector is configured detect mixture of an air bubble in the sealant discharged from the sealing gun, on a basis of a result of measurement by the measuring instrument.

The disclosure relates to an application device for applying an application agent (e.g. heat-conducting paste) into a cavity, in particular in a battery module of an electric battery. The application device according to the disclosure comprises a nozzle for dispensing the application agent through the nozzle and a first pressure sensor for measuring a first pressure reading (p.sub.A, p.sub.B) of the application agent upstream of the nozzle. The disclosure additionally provides a second pressure sensor for measuring a second pressure reading (p.sub.D) of the coating agent downstream of the first pressure sensor, in particular in the nozzle. Furthermore, the disclosure comprises a corresponding application method.

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.
