摘要： An apparatus for aligning a device having a fine pitch includes: a base plate, which has vacuum holes respectively formed at seating points for devices and suctions the devices with the vacuum pressure that allows minute movement as the vacuum pressure is applied in a state in which the devices are loaded; a jig plate, which is fixedly installed so as to be positioned on the upper portion of the base plate and has openings, in which the devices are received, in the same number as the number of the devices loaded on the base plate; and a base plate position adjusting means for finely moving the positions of the devices loaded on the base plate in X-Y-θ directions so as to position the devices in the openings (formed in the jig plate.

摘要： A method for aligning a device includes: loading devices sequentially on an upper surface of a base plate having vacuum holes; suctioning the loaded device with vacuum pressure that allows minute movement of the loaded device, as the vacuum pressure is applied while the device is loaded on the base plate; moving an alignment vision assembly positioned above the base plate to the upper portion of the device to be aligned and then lowering the alignment vision assembly; checking a position of the device with a vision means through a through hole and an opening in a state, in which an alignment block surrounds the device, so as to inform a controller of the coordinates of the device; and aligning the device by finely moving the base plate in X-Y-θ directions according to the coordinates so that the device is guided to two surfaces of the opening.

摘要： Disclosed is a device for automatically opening or closing a gas barrel valve. The device includes: a main plate installed so as to move up and down and to align the position of a gas barrel loaded in a cabinet; a gas barrel connecting portion installed on the lower portion of the main plate, separating an end cap from the gas barrel and storing the end cap, and then automatically screw-coupling a connector holder to a gas spray nozzle; a valve handle unit installed on the main plate so as to rotate around a first shaft and rotating a valve handle of the gas barrel such that the valve handle is locked or unlocked, while encompassing the valve handle of the gas barrel; and a valve handle opening or closing unit installed on the upper portion of the main plate so as to operate the valve handle unit in a direction, in which a valve of the gas barrel is opened.

摘要： A method for automatically opening or closing a gas barrel valve, includes: loading and aligning a gas barrel in a cabinet; separating an end cap from the gas barrel; screw-coupling a connector holder to a gas spray nozzle, from which the ends cap has been removed; winding a spring around a first shaft by enabling forward rotation of the first shaft while suppressing reverse rotation of the first shaft, which is installed in a valve handle holder so as to idle; opening a valve by enabling reverse rotation of a valve handle of the gas barrel while preventing forward rotation of the valve handle holder; and automatically closing the valve at the time of replacement of the gas barrel or when a gas leak is detected.
