Definitions

  • the present invention relates to a tape feeder.
  • a component mounting machine is conventionally provided as a machine that mounts an electronic component (hereinafter simply referred to as “component”) onto a substrate.
  • a mounting head takes out a component from a tape feeder by an absorbing nozzle and transfers and mounts it onto the substrate.
  • the tape feeder feeds a carrier tape having a plurality of rectangular component storage units (cavities) which store components and which are provided at predetermined intervals in a feed direction, and conveys the component to a component take-out region where component take-out is performed.
  • technologies related to the tape feeder are, for example, those described in Japanese Unexamined Patent Application Publication No. 2000-228600 (hereinafter referred to as Patent Reference 1) and Japanese Unexamined Patent Application Publication No. 2009-212194 (hereinafter referred to as Patent Reference 2).
  • a magnet is provided below an entire bottom surface of a component storage unit fed to a component take-out region. This suppresses, for example, standing of the component at the component storage unit.
  • a component storage position differs among the component storage units even in the same tape carrier. Therefore, in the component take-out by the mounting head, positional dislocation (absorption dislocation) from a predetermined component absorption position occurs, which consequently deteriorates positional accuracy of the component mounting.
  • carrier tapes of different vendors have different gap sizes at the component storage unit (a sum of gaps in the same direction on a plane between a side surface of the component storage unit and the component in a predetermined direction), but as shown in FIG. 19 , with an increase in the gap size at the component storage unit, an amount of positional dislocation increases, so that an absorption error is likely to occur.
  • the gap size at the component storage unit has become too small, with a decrease in the gap size, the amount of positional dislocation increases, so that the absorption dislocation is likely to occur. That is, in a case where the gap size at the component storage unit is not within a predetermined range (range shown by an arrow in FIG. 19 ), the absorption dislocation is likely to occur. Therefore, in component mounting by use of carrier tapes of different vendors, it is difficult to control the gap at the component storage unit in a stable manner, so that an absorption error, upright absorption, etc. are likely to occur.
  • a small-sized component inevitably has a large gap size at the component storage unit. Moreover, upon take-out of the small-sized component, the absorption dislocation has a great influence, resulting in failure to take out the component even if the absorption dislocation is small, so that the absorption error is likely to occur. Therefore, for the mounting of the small-sized component, it is strongly desired in particular to reduce the absorption dislocation.
  • a tape feeder feeds a carrier tape including a plurality of component storage units of a rectangular shape provided at predetermined intervals in a feed direction, and includes a first magnetic force region which is provided below a bottom surface of the component storage unit fed to a feed region so as to extend in the feed direction below one side of the bottom surface in a width direction and which attracts a component of the component storage unit fed to the feed region to one side in the width direction.
  • the component of the component storage unit in the feed region is attracted by the first magnetic force region to one side end of the component storage unit.
  • all the components of the component storage units are attracted to one side ends of the component storage units for alignment in the feed region, which therefore reduce absorption dislocation.
  • the tape feeder may include a second magnetic force region which is provided at back in the feed direction with respect to the first magnetic force region below the bottom surface of the component storage unit fed to the feed region and which attracts the component of the component storage unit fed to the feed region towards the back in the feed direction.
  • the first magnetic force region may be formed of a first magnet
  • the second magnetic force region may be formed of a second magnet
  • the first magnet and the second magnet may be integrated together to form an L-shaped magnet.
  • the component of the component storage unit moving in the feed direction in the feed region is attracted by the second magnetic force region to a rear end of the component storage unit in the feed direction by use of a force of feeding a tape.
  • all the components of the component storage units are attracted to corners of the component storage units for alignment in the feed region, which can therefore further reduce the absorption dislocation.
  • the first magnet may be provided below half of the bottom surface.
  • This consequently can suppress component standing and failure to perform component absorption by an absorbing nozzle due to a too strong force of attracting the component of the component storage unit by the first magnet.
  • the first magnet may be formed of an elastic body.
  • the tape feeder may further include an elastic member of a plate-like shape supporting the bottom surface of the component storage unit fed to the feed region, wherein the first magnet may be attached to a surface of the elastic member opposite to a side on which the bottom surface is placed.
  • a magnetic force is inversely proportional to a square of a distance, but a distance between the first magnet and the carrier tape can be kept constant, thus permitting control of the force of attracting the component by the first magnet.
  • the first magnet may be provided below bottom surfaces of the plurality of the component storage units fed to the feed region.
  • a front end part of the first magnet in the feed direction may be provided below a portion occupying one fourth of an area of the bottom surface.
  • a carrier tape feeding method is a method of feeding in a tape feeder a carrier tape including a plurality of component storage units of a rectangular shape provided at predetermined intervals in a feed direction, and attracts a component of the component storage unit fed to a feed region in the tape feeder to one side of a bottom surface of the component storage unit in a width direction and towards back in the feed direction.
  • the absorption dislocation can be reduced, and thus cavity variation can be absorbed and the component take-out positions can be aligned to stabilize a component absorption rate and mounting accuracy.

  • the magnet 150 is not limited to this as long as it generates a magnetic force of attracting the components 140 in the feed region to the ends of the component storage units 141 .
  • the magnet 150 may be formed of the first magnet 151 and the second magnet 152 separated from each other.
  • the second magnet 152 is so provided as to be separated from the component storage unit 141 at the component take-out position by the distance sandwiching the two component storage units 141 , although not the magnet 152 is limited to this as long as it can is separated by a distance that does not impede the component take-out by the absorbing nozzle with consideration given to, for example, a magnetic force of the second magnet 152 and the component pitch.
  • the second magnet 152 may be provided below the component storage unit 141 next to the component storage unit 141 at the component take-out position.
  • the second magnet 152 may be so provided as to be separated from the component storage unit 141 at the component take-out position by a distance sandwiching the three or more component storage units 141 .
  • the first magnet 151 is provided below the bottom surfaces of the component storage units 141 in the feed region so as to cover the half areas of the bottom surfaces of the component storage units 141 .
  • the first magnet 151 may be provided below the bottom surfaces of the component storage units 141 in the feed region so as to cover not all but only part of the bottom surfaces of the component storage units 141 in the width direction, without being limited to the half areas.
  • the first magnet 151 is provided below the bottom surfaces of the three component storage units 141 fed to the feed region, although the number is not limited to 3 as long as the first magnet 151 is provided below the bottom surfaces of the plurality of component storage units 141 fed to the feed region.
  • the first magnet 151 is provided.
  • the first magnet 151 is not limiting as long as the tape feeder has a first magnetic force region which is provided below the bottom surfaces of the component storage units 141 fed to the feed region so as to extend in the feed direction below one side of the bottom surfaces in the width direction and which attracts the components of the component storage units 141 fed to the feed region to one side in the width direction.
  • the first magnetic force region is formed of one first magnet 151 but may be formed of a plurality of magnets.
  • the second magnet 152 is provided.
  • the second magnet 152 is not limiting as long as the tape feeder has a second magnetic force region which is provided at the back in the feed direction with respect to the first magnetic force region below the bottom surfaces of the component storage units 141 fed to the feed region and which attracts the components of the component storage units 141 fed to the feed region to the back in the feed direction.
  • the second magnetic force region is formed of one second magnet 152 but may be formed of a plurality of magnets.
  • vibration is added to the tape feeder before the components 140 are attracted to the ends of the component storage units 141 by the magnet 150 .
  • the tape feeder may be tilted to thereby move the components 140 to the ends of the component storage units 141 .

  • FIGS. 18A to 18C Configuration of FIGS. 18A to 18C is effective for, for example, the component 140 like an LED (Light Emitting Diode) shown in a sectional view of FIG. 18D .
  • the reasons are as follows.
  • the resistor and the capacitor use Ni (nickel) plating for internal and external electrodes and have some members formed of a magnetic body.
  • a lead frame is formed of a material containing a large quantity of gold or silver with small current loss
  • an electrode 180 is also formed of not nickel-plating but gold-flash plating, and these members are formed of a material hardly or less susceptible to the magnetic force.
  • the electrode 180 and a component body 181 formed on the same bottom surface of the LED are formed of different materials, for example, gold-flash plating and glass epoxy region; therefore, they have different surface slip coefficients, and thus are hard to slip in the component storage unit 141 .
  • an area in which the component body 180 and the component storage unit 141 are in contact with each other is large, resulting in difficulty in slipping in the component storage unit 141 .
  • the electrode 180 and the component body 181 formed on the same bottom surface have unevenness on their front surfaces, thus frequently providing configuration such that slipping in the component storage unit 141 is difficult.
  • the present invention can be used for a tape feeder and a carrier tape feeding method using the tape feeder, and can be used especially for a component mounting machine, etc.
