  • Publication number: 20220272883
    Abstract: A board work machine includes a board holding portion configured to hold a board, a work head configured to hold a lead component having a lead wire and insert the lead wire into a through-hole formed in the board, a lead wire cutting device configured to cut the lead wire inserted into the board by relatively reciprocally moving a first blade portion and a second blade portion, a distortion sensor configured to detect distortion of at least one of the first blade portion or the second blade portion, and a control device configured to drive the lead wire cutting device to acquire a value from the distortion sensor when the lead wire is not inserted into the board.

  • Patent number: 11202400
    Abstract: A recognition device includes an imaging device that images a tip of the lead of a lead component multiple times at different shutter speeds, and multiple pieces of captured image data corresponding to the multiple times of imaging are generated. Then, it is determined whether the tip position of the lead is recognizable based on each of the multiple pieces of captured image data, and a shutter speed between the fastest shutter speed and the slowest shutter speed among the shutter speeds at the time of imaging according to the pieces of captured image data, which are determined to be recognizable, is determined as the optimum shutter speed. By determining the optimum shutter speed in this manner, the exposure light amount at the time of imaging can be stabilized regardless of the shape of the tip of the lead, and the tip position of the lead can be appropriately recognized.

  • Patent number: 11039559
    Abstract: A control device is configured as an information processing apparatus which is used for a mounting apparatus for mounting a component on a board. The control device acquires an image, including at least a reference portion in a state where a component is gripped by a component gripper having a positioning grip portion that grips the component in a positioned state, and having the reference portion that represents a reference position serving as a predetermined relative position to the position of the component gripped by the positioning grip portion, acquires a position of the reference portion based on the acquired image, and acquires a position of the component based on the relative position to the acquired position of the reference portion.

  • Patent number: 10537049
    Abstract: A component attachment apparatus picks up a first component supplied to supply position of a first stick feeder with a head, assembles the first component and a second component by inserting a lead of the first component held by the head into an insertion hole of the second component supplied to supply position of a second stick feeder, and then attaches the assembly to a board. Therefore, in comparison with a case where the first component attached to the second component after the second component is attached to the board, it is possible to stably attach the components to the board with low influence of warping of the board.

  • Patent number: 10462949
    Abstract: A reel holding device is provided. The device includes: a case which accommodates the plurality of component supply reels to be aligned in a direction of a reel axial line; outer circumferential support members which are built between two sides walls of the case, and support outer circumferences of the multiple component supply reels to be rotatable; and a deviation preventing member which prevents the component supply reels from deviating from the outer circumferential support members. At least one of the outer circumferential support members and the deviation preventing member is an integrated rod-like member which is built between the two side walls.

  • Patent number: 10342168
    Abstract: A feeder includes a discharge guide member which is provided on a feeder main body to communicate with a tape discharging section and guides such that a carrier tape which is discharged from the tape discharging section heads downward, a peeling member which is provided on the feeder main body and peels a cover tape from the carrier tape before the carrier tape which is conveyed by a front side sprocket reaches the tape discharging section, and a contacting and positioning member which is provided on the feeder main body, causes the cover tape which covers the carrier tape which is conveyed by the front side sprocket to contact the peeling member, and positions the carrier tape from which the cover tape is peeled and which is discharged from the tape discharging section at a regular position inside the discharge guide member.

  • Patent number: 10297039
    Abstract: With a recognition device of the present invention, when a target component that is an imaging target is moved in a direction from one to another of an upper limit imaging position and a lower limit imaging position, a protruding section of the target component is imaged at each of a predetermined pitch (0.1 mm). Then, it is determined whether it is possible to recognize the position of the protruding section of the target component based on image data of each pitch (O: recognition possible, X: recognition not possible). Here, from among imaging positions (H4 to H10) according to image data for which it was determined to be possible to recognize the position of the protruding section of the target component, a position (H7) that is at a central point between a position closest to the upper limit imaging position (H4) and a position closest to the lower limit imaging position (H10) is decided as a recommended imaging position.
