Definitions

  • Substrate-related work machines use a work head that is movable within the machine to perform specified substrate-related work on a board.
  • a component placement machine serving as a substrate-related work machine picks up a component using, for example, a suction nozzle and places the component in a specified placement position on the board.
  • the component placement machine supports the suction nozzle by the placement head serving as the work head, allowing it to move up and down and rotate (see Patent Document 1).
  • the purpose of this specification is to provide a substrate-related operating machine that can securely support each working head while ensuring a range of motion for the working head.
  • This specification discloses a substrate-related operating machine that includes a first slide that is movably supported on a plurality of guide rails that are arranged along a horizontal first direction, and a second slide that moves the first slide in the second direction, and in which the plurality of guide rails are arranged to support the first slide movably in the first direction at three or more different support positions in a plane that includes the up-down direction and a horizontal second direction that intersects the first direction.
  • the first slide is supported at three or more different support positions, making it possible to reliably support the working head while ensuring a range of motion for the working head.

  • 10 is a flowchart showing a mounting process performed by a component mounting machine.
  • FIG. 2 is a top view schematically showing a multiple substrate made up of a plurality of unit substrates.
  • Component mounting machine 10 is a substrate-related operation machine that performs a predetermined substrate-related operation on board 90, and performs a mounting process to mount components on board 90 as the substrate-related operation.
  • Component mounting machine 10 constitutes a production line together with a plurality of other substrate-related operation machines that are installed in the transport direction of board 90. Each of the plurality of substrate-related operation machines is communicably connected to host computer 5, which controls the production line as a whole.
  • the substrate-related processing machines that make up the production line include a printer that prints solder on the substrate 90, a reflow oven that heats the substrate 90 with components mounted thereon to solder it, and an inspection machine that inspects whether the appearance or functionality of the product substrate is normal.
  • the configuration of the production line can be added to or modified as appropriate, depending on, for example, the type of product substrate being produced.
  • multiple production lines can be equipped with substrate-related processing machines such as a buffer device that temporarily holds the substrate 90 being transported, a substrate supply device, a substrate inversion device, various inspection devices, a shield mounting device, an adhesive application device, and an ultraviolet irradiation device.
  • the board transport device 20 sequentially transports the boards 90 in the transport direction and positions the boards 90 at predetermined positions within the machine. As shown in FIG. 2, the backup device 23 raises the backup pins 24 using the pin lifting device 25, and clamps the boards 90, which have been positioned at predetermined positions in the transport direction, between the pair of guide rails 22. After completing the component mounting process, the board transport device 20 transports the boards 90 out of the component mounting machine 10.
  • the number of holders 73 supported by a mounting head 70 configured as described above may vary depending on the type of mounting head 70.
  • the mounting head 70 may adopt various configurations in addition to the configuration in which multiple holders 73 are supported at equal intervals in a circular ring shape, as in this embodiment.
  • the mounting head 70 may adopt a configuration in which multiple holders 73 are arranged in a line or matrix.
  • the head moving device 40 includes an X drive device 41 (see Figure 2) that moves the X slide 50 in the X direction relative to the Y slide 60, and a Y drive device 46 that moves the Y slide 60 in the Y direction relative to the beam 13.
  • the X drive device 41 and Y drive device 46 are configured with linear motion mechanisms such as linear motors and ball screws.
  • the X drive device 41 is a linear motor
  • the Y drive device 46 is a ball screw device.
  • the Y slide 60 has a guide block 65 slidably engaged with a pair of guide rails 47 provided on the beam 13.
  • the pair of guide rails 47 and the guide block 65 function as a Y-axis guide device that guides the movement of the Y slide 60 in the Y direction.
  • the Y-axis guide device is a suspension type that supports the Y slide 60 suspended from the pair of guide rails 47 so that it can move in the Y direction, ensuring a large range of movement in the X direction.
  • the X slide 50 comprises a plurality of carriages 52 movably supported along a pair of guide rails 61 provided on the Y slide 60.
  • the pair of guide rails 61 and the carriages 52 function as an X-axis guide device that guides movement of the X slide 50 in the X direction.
  • the X drive device 41 which is a linear motor, comprises a pair of stators 42, a mover 43, and a cooling device 44, as shown in FIG. 2.
  • the width Hw of the mounting heads 70 is reduced, for example by reducing the width of the X slide 50 that supports the mounting heads 70, there is a concern that the support force of the Y slide 60 relative to the X slide 50 will decrease. Increasing the maximum speed or maximum acceleration of the X-direction movement of the mounting heads 70 in this situation could generate vibrations, which could affect mounting accuracy. Therefore, in this embodiment, the following configuration of the head moving device 40 is adopted to ensure the movable range Mr of multiple mounting heads 70 while reliably supporting each of the mounting heads 70.
  • each of the two carriages 52 is a wide carriage 52W, as shown in Figure 5, whose width supported by the guide rails 61 is wider than the X-direction width Hw of the mounting head 70 supported by the X-slide 50.
  • the accommodation section 55 extends in the X direction parallel to the guide rail 61 and is formed in a groove shape to avoid interference with the carriage 52.
  • the two X slides 50L, 50R are moved in the X direction by an X drive unit 41, which is a linear motor.
  • the two X slides 50L, 50R are individually supported by two pairs of guide rails 61, while sharing a pair of stators 42 in the X drive unit 41.
  • the X drive unit 41 controls the power supply to multiple movers 43 provided on each of the two X slides 50L, 50R, to move the X slides 50.
  • the two mounting heads 70L, 70R are set with a minimum distance Dc at which they are allowed to approach each other, taking into account their respective X-direction widths Hw and the distance required to prevent interference.
  • Figure 6 shows the two mounting heads 70L, 70R at their closest position.
  • the two mounting heads 70 are of the same type and are compatible with each other.
  • the two X-slides 50L, 50R are of different types, they each support mounting heads 70 of the same type.
  • the width Ws occupied by the pair of X-slides 50L, 50R in the X-direction is smaller than the width Wh occupied by the pair of mounting heads 70.
  • the width Hw in the X direction of the two mounting heads 70 is set to be 20% or less of the movable range Mr of the mounting heads 70, which is set based on the minimum distance Dc at which the two mounting heads 70 are allowed to approach each other. This allows a larger number of suction nozzles 74 to be used overall, while increasing the movable range Mr of the mounting heads 70.
  • the X slide 50 is supported by the support range Cr of the wide carriage 52W, thereby improving the support force of the Y slide 60 and suppressing the generation of vibrations caused by the operation of the X slide 50.
  • This makes it possible to increase the maximum speed and maximum acceleration of movement of the mounting head 70 in the X direction, thereby shortening the time required for the mounting process.
  • the support ranges CrL and CrR of the pair of wide carriages 52W in the left and right directions overlap each other. This allows the mounting heads 70 supported by the pair of X slides 50 to be closer together than before, ensuring a larger movable range MrL and MrR.
  • the control device 85 can recognize placement errors by, for example, acquiring a reference mark attached to the top surface of the feeder 31.
  • the picking position corresponding to the picking operation of the right-side mounting head 70R may fall within the allowable range for the picking operation by the suction nozzle 74 of the right-side mounting head 70R, even when taking into account the placement error of the feeders 31.
