摘要： An applicator for dispensing a liquid conformal coating material onto a substrate. The applicator includes a body assembly with a liquid flow passage having a liquid inlet adapted to receive the coating material and a liquid outlet. A valve seat is positioned between the liquid flow passage and the liquid outlet. A valve stem is mounted in the body assembly for reciprocating movement between an open position and a closed position. The valve stem includes a first end and a second end. The first end of the valve stem engages the valve seat in the closed position to stop flow of the liquid coating material through the outlet and disengages from the valve seat in the open position to allow flow of the liquid coating material through the outlet. A valve actuating mechanism is operative to move the valve stem from the open position to the closed position and is further operative to move the valve stem from the closed position to the open position. A resilient dampening element is operatively coupled between part of the body assembly and the valve stem. The resilient dampening element provides a biasing force against the valve stem as the valve stem moves from the closed position to the open position to reduce rebounding movement of the valve stem toward the closed position.
摘要翻译：用于将液体保形涂层材料分配到基底上的涂抹器。施加器包括具有液体流动通道的主体组件，该液体流动通道具有适于接收涂层材料的液体入口和液体出口。阀座位于液体流动通道和液体出口之间。阀杆安装在主体组件中，用于在打开位置和关闭位置之间往复运动。阀杆包括第一端和第二端。阀杆的第一端在闭合位置处接合阀座，以阻止液体涂层材料通过出口流动并且在打开位置与阀座脱离接合以允许液体涂料通过出口流动。阀致动机构可操作以将阀杆从打开位置移动到关闭位置，并且还可操作以将阀杆从关闭位置移动到打开位置。弹性阻尼元件可操作地联接在主体组件的一部分和阀杆之间。当阀杆从关闭位置移动到打开位置时，弹性阻尼元件提供抵靠阀杆的偏置力，以减小阀杆朝向关闭位置的反弹运动。

摘要： A film coater for applying a coating material to selected areas on a target substrate, such as a printed circuit board, having a vented dispenser body with a plunger moveable therein between an open and closed position. A flow of pressurized air which moves the plunger to the open position is controlled by a valve carried by the dispenser body, and a plurality of springs return the plunger to the closed position. The number of return springs is selected to provide a variable biasing force so that movement of the plunger is controlled to eliminate or at least significantly reduce hammering, tapering and drooling, particularly when the dispenser is operated intermittently.

摘要： Apparatus and methods for spray coating selected areas of a circuit board with an insulative coating material without coating regions of the circuit board to be left uncoated. A liquid spray device emits the coating material and an air assist attachment connected to the liquid spray device directs jets of air into impinging relation with the coating material emitted therefrom to transform the coating material into an atomized, shaped spray pattern for coating the selected areas. The air assist attachment can be disabled so that the spray device transforms the coating material into a non-atomized, shaped spray pattern for coating selected areas without coating regions of the circuit board to be left uncoated.

摘要： Systems and methods for applying liquid coating materials to a substrate, such as an electronic component or circuit board. A control system of a coating system controls an applicator and a robot moving the applicator to apply the liquid coating material to the substrate in accordance with the information contained in a coating program. The control system determines a volume of liquid coating material actually dispensed onto the substrate during the coating program, and compares the dispensed volume to a desired dispensed volume of liquid coating material to produce an error signal representing the difference between the calculated and desired volume values. The control system uses the error signal to change the dispensed volume of liquid coating material on a subsequent substrate by a future coating program.
