  • Patent number: 10413986
    Abstract: 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.

  • Patent number: 10412870
    Abstract: In a board work machine that performs board work with reference to a reference mark provided on a board, in a case of performing board work with respect to a board provided with overall reference mark and local area reference mark that acts as a reference for a local area as reference marks, when recognizing the reference marks by imaging, checking is performed as to whether a recognized reference mark is recognized correctly. For this checking, when checking whether the position deviation amount from a normal position and the relative position deviation amount of an imaging target identified as a reference mark is within the range of a set tolerance, set tolerances for a local area reference mark are smaller than set tolerances for an overall reference mark.

  • Publication number: 20190274238
    Abstract: A component picked up by a suction nozzle of a component mounting machine is imaged by a camera, the captured image is processed by an image recognition system to recognize the component, the image is determined to be normal or abnormal based on the recognition result, and in addition to classifying the image as a normal image or an abnormal image and storing the image in a storage device, component mounting boards, unloaded from a component mounting machine, are inspected with an inspection device. A stored image reclassification computer acquires the inspection result from the inspection device, reclassifies the normal image stored in the storage device, based on the inspection result, as an image whose determination as a normal image is suspect or as an image whose determination as a normal image is not suspect, and then stores the normal image in the storage device.

  • Publication number: 20190265749
    Abstract: In the case where multiple individual work devices respectively executing a sequence of multiple tasks are controlled in an integrated manner by an integrated control device, log analysis among the multiple individual work devices is difficult. One of four individual work devices transmits time inquiry signal to main integrated control device via serial communication cable. Main integrated control device returns the time at time at which time inquiry signal was received to the one of four individual work devices to which time inquiry signal was transmitted. One of four individual work devices receives a reply from main integrated control device at time, adds the communication time to the time at time, and calculates the time at time. One of four individual work devices starts the calculation of the in-device time from calculated time as a starting point. One of four individual work devices logs based on in-device time.

  • Patent number: 10398070
    Abstract: A suction nozzle includes a suction pad portion at a tip of an air pipe formed to be larger than the air pipe, in which a resistance cavity which causes resistance and decreases air flow speed when a positive pressure is applied is formed between a flow path and a cavity portion. In the suction nozzle, since the resistance cavity is formed, a positive pressure is applied by the air whose flow speed is suppressed and the suction release of the component is performed. The resistance cavity may be a cavity having a slit shape.
