Abstract

A chip component feeder is provided which includes a chip component storage box, a pick-up slider, a first feeding unit, and a second feeding unit. The pick-up slider slides to enter an outlet of the chip component storage box for picking up chip components and leads them to a feeding path formed in the first feeding unit communicating with the second feeding unit. The feeding path of the first feeding unit has a rectangular cross section suitable for the chip components of rectangular shape as well as square or circular shape.

Claims

1. A chip component feeding apparatus comprising:

a storage member having formed therein a storage chamber for storing therein chip components, the storage chamber having an outlet formed in a lower portion thereof;

a first feeding unit having formed therein a feeding path for feeding the chip components stored in the storage chamber of said storage means, the feeding path having a rectangular cross section;

a pick-up slider sliding between an upper limit leading to the outlet of said storage member and a lower limit along a given sliding path defined on said first feeding unit including groove means to pick up and carry the chip components stored in the storage chamber of said storage member and lead the picked up chip components into the feeding path of said first feeding unit as said pick-up slider moves between said upper and lower limits; and

a second feeding unit for moving the chip components through the feeding path of said first feeding unit to a pick-up station.

2. A chip component feeding apparatus as set forth in claim 1, wherein said storage member is geometrically oriented to lead the chip components to the outlet.

3. A chip component feeding apparatus as set forth in claim 2, wherein the feeding path of said first feeding unit is sized to prevent the more than two chip components from being inserted thereinto while overlapping with each other.

4. A chip component feeding apparatus as set forth in claim 3, wherein the feeding path has a height which is less than twice the thickness of the chip components.

5. A chip component feeding apparatus as set forth in claim 1, further comprising a partition member within said storage member to define a space over the outlet for preventing the weight of the chip components in an upper portion of the storage chamber from acting directly on the chip components around the outlet.

6. A chip component feeding apparatus as set forth in claim 1, further comprising a drive unit connecting with said pick-up slider and said second feeding unit, said drive unit synchronously driving said pick-up slider along the given sliding path and said second feeding unit to feed the chip components to the pick-up station.

7. A chip component feeding apparatus as set forth in claim 6, wherein said drive unit includes a lever, a first intermediate lever connecting with the lever, and a second intermediate lever connecting with the first intermediate lever through a spring, the second intermediate lever connecting at its end with said pick-up slider and being moved by the lever through the first intermediate lever and the spring.

8. A chip component feeding apparatus as set forth in claim 1, wherein said pick-up slider has an end portion entering the outlet of said storage member according to the sliding movement, the end portion having formed thereon a tapered surface defining a chip component inlet opening together with an end of the groove.

9. A chip component feeding apparatus as set forth in claim 1, wherein said pick-up slider has a length an end portion of which enters the outlet of said storage member according to the sliding movement of the pick-up slider and which is stepped to have a decreased thickness.

10. A chip component feeding apparatus as set forth in claim 1, wherein the outlet of said storage member is sized to prevent the more than two chip components from being inserted thereinto while overlapping with each other.

11. A chip component feeding apparatus as set forth in claim 1, wherein said pick-up slider, when reaching the lower limit, defines an outlet chamber in the outlet of said storage member for dropping thereinto the chip components which are in a given position.

12. A chip component feeding apparatus as set forth in claim 1, wherein said pick-up slider has an end portion entering the outlet of said storage member according to the sliding movement, the end portion being flush with an inner wall of the storage chamber around the outlet when the pick-up slider reaches the lower limit.

13. A chip component feeding apparatus as set forth in claim 1, further comprising a protrusion formed on the given sliding path of said pick-up slider for preventing the chip components from being locked in the given sliding path.

14. A chip component feeding apparatus as set forth in claim 1, wherein said pick-up slider is formed with a square member having a given length, the groove being formed in a first corner portion of the square member, a chamfered or rounded portion being formed on a second corner portion opposite the first corner portion.

15. A chip component feeding apparatus as set forth in claim 1, wherein said pick-up slider includes a base member, a sliding member, and a spring, the sliding member being slidably mounted on the base member and spring-loaded by the spring.

16. A chip component feeding apparatus as set forth in claim 1, wherein the feeding path of said first feeding unit has a cross sectional area greater than a diagonal of the chip components having a substantially cubic shape, and has a flat bottom surface.

17. A chip component feeding apparatus as set forth in claim 1, further comprising an extension formed on the sliding path of said pick-up slider which extends over the inlet of the feeding path to orient insertion of the chip components into the feeding path.

18. A chip component feeding apparatus as set forth in claim 1, further comprising a pick-up unit disposed at the pick-up station, the pick-up unit including a lever, a sliding member, and a stopper, the stopper being arranged to retain the chip components fed by the second feeding unit at the pick-up station and being rotated by the sliding member according to movement of the lever to release the retaining of the chip components for providing access to the chip components.

19. A chip component feeder moving assembly comprising:

a plurality of chip component feeders including, (a) a storage member having formed therein a storage chamber for storing therein chip components and geometrically oriented to lead the chip components to an outlet formed in a lower portion of the storage member, (b) a first feeding unit having formed therein a feeding path having a rectangular cross section for feeding the chip components stored in the storage chamber of said storage means, (c) a pick-up slider sliding between an upper limit leading to the outlet of said storage member and a lower limit along a given sliding path defined on said first feeding unit including groove means to pick up and carry the chip components stored in the storage chamber of said storage member and leading the picked up chip components into the feeding path of said as said pick-up slider moves between said upper and lower limits, and (d) a second feeding unit for moving the chip components through the feeding path of said first feeding unit to a pick-up station;

a base table mounting thereon said plurality of the chip component feeders; and

a feeders holding member supported on said base table, said feeder holding member for holding said plurality of the chip component feeders side by side.

20. A chip component feeder moving assembly as set forth in claim 19, wherein said feeder holding member includes a bar member having formed therein a plurality of grooves each retaining one of said chip component feeders.
