Abstract

A picker assembly includes a picker, a driving member coupled to the picker, the driving member adjusting a position of the picker, a pair of first fixing members on a lower surface of the driving member, the pair of first fixing members being adjacent to a portion at which the driving member and the picker are connected, and a pair of second fixing members on the picker, the pair of second fixing members being coupled to respective first fixing members through latching and fixing.

Claims

1. A picker assembly, comprising:

a picker;

a driving member coupled to the picker, the driving member adjusting a position of the picker;

a pair of first fixing members on a lower surface of the driving member, the pair of first fixing members being adjacent to a portion at which the driving member and the picker are connected, and each of the first fixing members including a latch member movable linearly along a longitudinal direction of the driving member; and

a pair of second fixing members on the picker, the pair of second fixing members being coupled to respective first fixing members through latching and fixing.

2. The picker assembly as claimed in claim 1, wherein each of the first fixing members includes:

a fixing body on the lower surface of the driving member; and

the latch member coupled to the fixing body, the latch member being movable linearly within the fixing member along the longitudinal direction of the driving member.

3. The picker assembly as claimed in claim 2, wherein:

the fixing body includes an accommodation part with an opening therein, and

the latch member includes;

an insertion part accommodated in the accommodation part, and

a protruding part extending from the insertion part to an outside of the accommodation part, the protruding part being exposed to the outside of the accommodation part.

4. The picker assembly as claimed in claim 3, wherein the second fixing members are latched onto the protruding parts of the respective first fixing members.

5. The picker assembly as claimed in claim 3, further comprising an elastic member in the accommodation part, the elastic member being between the insertion part and the fixing body.

6. The picker assembly as claimed in claim 5, further comprising an operation hole through the fixing body, the insertion part being coupled to an operation part having a rod shape and extending through the operation hole.

7. The picker assembly as claimed in claim 2, wherein:

the fixing body has a guide rib on an external surface thereof at a portion that contacts the picker, and

the picker has a guide groove corresponding to the guide rib, the guide groove being on an external surface thereof.

8. The picker assembly as claimed in claim 7, wherein the guide rib and the guide groove extend along vertical directions.

9. The picker assembly as claimed in claim 1, further comprising:

a coupling protrusion on a surface of one of the picker and the driving member; and

an insertion groove on a surface of another of the picker and the driving member, the coupling protrusions being inserted into the insertion groove.

10. A picker assembly, comprising:

a picker;

a driving member coupled to the picker, the driving member adjusting a position of the picker;

a pair of first fixing members on one of the driving member and the picker, the pair of first fixing members being adjacent to a portion at which the driving member and the picker are connected, and each of the first fixing members including a latch member movable linearly along a longitudinal direction of the driving member; and

a pair of second fixing members on the other of the picker and the driving member, the pair of second fixing members being coupled to the pair of first fixing members through latching and fixing.

11. The picker assembly as claimed in claim 10, wherein each of the first fixing members includes:

a fixing body; and

the latch member coupled to the fixing body to be movable linearly within the fixing member, the latch member having an oblong shape along an imaginary line connecting the picker with the driving member.

12. The picker assembly as claimed in claim 11, wherein the latch member receives force in a direction oriented toward the second fixing member.

13. The picker assembly as claimed in claim 11, wherein:

the fixing body includes an accommodation part having an opening therein, and

the latch member includes;

an insertion part accommodated in the accommodation part, and

a protruding part extending from the insertion part and exposed to an outside of the accommodation part.

14. The picker assembly as claimed in claim 10, wherein each of the second fixing members has a latch shape.

15. The picker assembly as claimed in claim 14, wherein the second fixing member has a latch part at an end portion thereof to protrude in a direction of the latch member.

16. A picker assembly, comprising:

a picker;

a driving member coupled to the picker, the driving member adjusting a position of the picker;

first fixing members on the driving member, each of the first fixing members including a latch member movable linearly along a longitudinal direction of the driving member; and

second fixing members on the picker, each of the second fixing members including a hook-shaped portion latched onto the latch member of a respective first fixing member.

17. The picker assembly as claimed in claim 16, wherein each of the first fixing members includes:

a fixing body on the driving member; and

the latch member extending from the fixing body to be exposed to an exterior of the fixing body, the latch member being movable linearly within the fixing member.

18. The picker assembly as claimed in claim 17, wherein the hook-shaped portion of the second fixing member is latched onto the latch member of the first fixing member.

19. The picker assembly as claimed in claim 18, wherein the hook-shaped portion of the second fixing member includes:

a first portion extending horizontally from a side surface of the picker;

a second portion extending vertically from the first portion toward the driving member; and

a third portion extending from the second portion and curving around a top of the latch member of the first fixing member.

20. The picker assembly as claimed in claim 19, wherein the second portion of the second fixing member has a slanted surface facing the latch member of the first fixing member, and the latch member has a slanted surface facing the slanted surface of the second portion of the second fixing member, the two slanted surfaces being complementary.
