Patent number: 10569351Abstract: A control device of soldering device identifies the type of lead component to be soldered when soldering multiple types of lead components sequentially with jet device and reads out a value of a soldering parameter corresponding to the lead component type from an HDD. Then, the control device controls jet device so that the lead component is soldered based on the value of the soldering parameter. As a result, the lead of the lead component is soldered with the value of the soldering parameter corresponding to the type of the lead component.Type: GrantFiled: August 1, 2016Date of Patent: February 25, 2020Assignee: FUJI CORPORATIONInventors: Satoru Otsubo, Noriaki Iwaki

Patent number: 10470350Abstract: A work machine including a flow device for flowing molten solder from under a circuit board, and a backup pin for supporting the circuit board from below while a lead of a leaded component is being inserted into a through-hole, which are moved separately under the circuit board. Thus, when the circuit board needs to be supported, the backup pin can be moved to any position, and when solder needs to be applied, the backup pin can be moved to a position that does not obstruct operation of the flow device. Accordingly, as well as guaranteeing operation of the flow device, it is possible to support the circuit board with the backup pin as required, thus improving practicality of the work machine.Type: GrantFiled: April 27, 2015Date of Patent: November 5, 2019Assignee: FUJI CORPORATIONInventors: Satoru Otsubo, Kazuya Degura

Patent number: 10413986Abstract: A soldering device includes a detection sensor which can detect a liquid level height of molten solder inside a solder bath. It is determined whether or not a detection height which is the detected liquid level height is greater than or equal to a first set height which is arbitrarily set. In a case where the detection height is greater than or equal to the first set height, it is estimated that the amount of molten solder capable of performing a soldering work for a predetermined number or more of boards is stored in the solder bath. The amount of molten solder stored in the solder bath is estimated by multiplying a difference between a detection height which is the detected liquid level height of the molten solder and a second set height which is preset, by an area inside the solder bath in a horizontal direction.Type: GrantFiled: June 23, 2015Date of Patent: September 17, 2019Assignee: FUJI CORPORATIONInventors: Kazuya Degura, Satoru Otsubo

Patent number: 9999168Abstract: A board conveyance device provided with multiple engaging sections that engage with a circuit board. When the conveyance direction is a first direction and the board is large, a claw out of two claws is set to a stopping state. A shuttle is moved up to the movement end on the downstream side in the first direction and two arms rotate. A lever rotates accompanying rotation of a rotating body to a disengaged position by a lever rotating section of a stopping device and an arm unit is able to be disconnected from a moving body. An arm holding section engages with an engaging section to prevent movement in the x direction. The moving body is moved in a second direction with the arm unit held by the stopping device. The claw is set to be in the stopping state and is not used in conveyance of the board.Type: GrantFiled: March 20, 2014Date of Patent: June 12, 2018Assignee: FUJI MACHINE MFG.
