Patent ID: 8733273

Claim:
An adhesive ejecting apparatus, comprising: a reservoir unit configured to store adhesive to be applied onto a to-be-joined member; a flow pipe connected to the reservoir unit and through which the adhesive stored in the reservoir unit flows; and at least an ejecting mechanism connected to the flow pipe and configured to eject the adhesive toward the to-be-joined member, wherein the reservoir unit comprises: an outlet through which the adhesive stored in the reservoir unit is sent out to the ejecting mechanism; and an inlet through which the adhesive flowing through the flow pipe is returned to the reservoir unit, one end of the flow pipe is connected to the outlet, another end of the flow pipe is connected to the inlet, the ejecting mechanism comprises: at least an ejector unit configured to eject the adhesive toward the to-be-joined member; a supply unit configured to supply the ejector unit with the adhesive flowing from the flow pipe; a distribution unit configured to send a predetermined amount of adhesive supplied by the supply unit to the ejector unit, and to return the rest of the supplied adhesive to the flow pipe; and a restricting unit disposed between the distribution unit and the flow pipe and configured to restrict an amount of adhesive to be returned to the flow pipe, the supply unit is configured to supply adhesive from the flow pipe to the ejector unit in an amount larger than a specified ejection amount of adhesive to be ejected by the ejector unit, the flow pipe and the adhesive reservoir unit define a first flow path for circulating the adhesive therethrough, the flow pipe, the adhesive reservoir unit, and the ejecting mechanism define a second flow path for circulating the adhesive therethrough, the restricting unit of the ejecting mechanism is within the second flow path but outside the first flow path, in the second flow path, the supply unit is upstream of the distribution unit, the ejector unit is coupled to the distribution unit, and the restricting unit is downstream of the distribution unit, the supply unit includes a pump and a pump controller, the distribution unit includes a first pipe connecting the pump and the restricting unit, and a second pipe connecting the ejector unit to the first pipe at a location upstream of the restriction unit and downstream of the pump.
