  • Patent number: 10994951
    Abstract: An electronic component handler includes an electronic component transporter transporting an electronic component in an arrangement state where a shuttle plate is arranged, the shuttle plate having a recess receiving the electronic component, a light source casting light, a light receiver receiving the light, a detector detecting presence/absence of the electronic component in the recess, and a negative pressure generator putting the recess under a negative pressure. The shuttle plate has a first flow path. The electronic component transporter has: a shuttle plate fastener having a second flow path communicated with the first flow path in the arrangement state and having the shuttle plate fixed thereto in the arrangement state, a transmission member sealing the second flow path and transmitting the light, and a driver driving the shuttle plate fastener. The negative pressure generator is coupled to the second flow path and sucks the electronic component in the recess.

  • Publication number: 20200300782
    Abstract: A handler that transports an electronic component (IC device) to a test unit includes a holding member (shuttle plate) including a recess having a colored bottom portion and housing the electronic component in the recess, an imaging unit (imaging device) that images the recess, and a control unit that compares a reference area of the bottom portion previously calculated from a plan view area of the electronic component and a plan view area of the bottom portion with a detection area of the bottom portion detected from an image captured by the imaging unit, and determines presence or absence of the electronic component housed in the recess or whether or not a position of the electronic component housed in the recess is good.

  • Patent number: 10591534
    Abstract: An electronic component transport apparatus includes: an inspection region in which an inspection portion that inspects the electronic component can be disposed; a supply transport region to which the electronic component before the inspection by the inspection portion is transported; a collect transport region to which the electronic component after the inspection by the inspection portion is transported; and an imaging portion which is capable of imaging the first mounting member or the second mounting member, in which it is possible to determine at least one of the presence or absence of the electronic component and a posture of the electronic component in the first mounting member or the second mounting member based on an imaging result obtained by imaging by the imaging portion, and to notify an operator of a determination result.

  • Publication number: 20200071090
    Abstract: There is provided an electronic component handler for transporting an electronic component, the handler including a shuttle having a placement surface on which the electronic component is placed and moving from a first position to a second position, and a positioning unit provided in the shuttle and positioning the electronic component by coming into contact with the electronic component placed on the placement surface, in which the positioning unit has a first positioning member and a second positioning member that are driven to move or rotate with respect to the shuttle, when the shuttle is located at the first position, the electronic component is placed on the placement surface, and a distance between the first positioning member and the second positioning member when the shuttle is located at the first position is longer than a distance between the first positioning member and the second positioning member when the shuttle is located at the second position.

  • Publication number: 20180117767
    Abstract: A robot system includes a supply section configured to supply an object, a first test section group including a plurality of first test sections configured to test the supplied object, a second test section group including a plurality of second test sections configured to test the supplied object, a collecting section configured to collect the tested object, and a robot including a robot arm and configured to hold, convey, and release the object. The robot is capable of collectively conveying a plurality of the objects. A total of conveyance times for the conveyance of the object by the robot from the supply to the collection of the object is shorter than a total of processing times for the holding and the release of the object by the robot.
