Abstract

A cleaning apparatus includes a case and a cleaning head. The cleaning head is disposed on the case, and provided with a plurality of tines. The tines are separately arranged abreast. The tines are used to extend into gaps between plural conductive terminals of a semiconductor product for cleaning the semiconductor product.

First claim

What is claimed is:

1. A cleaning apparatus being applicable to clean a semiconductor product in which the semiconductor product includes a plurality of conductive terminals arranged at intervals, and gaps are formed between the conductive terminals, the cleaning apparatus comprising:
a case; and
a cleaning head comprising:
a main body comprising an expandable assembly expandably disposed in the case, and an adjustment portion movable disposed on the case, and connected to the expandable assembly for controlling an expansion of the expandable assembly; and
a plurality of tines separately arranged on the main body abreast, for respectively extending into the gaps of the conductive terminals, wherein a space formed between two neighboring ones of the tines is configured to only receive single one of the conductive terminals of the semiconductor product,
wherein the expandable assembly extends in an axial direction, and the tines are arranged abreast on one side of the expandable assembly in the axial direction such that space intervals formed between the tines are correspondingly adjustable when the expandable assembly extends.

2. The cleaning apparatus of claim 1 , wherein the tines are adjustably arranged on the main body such that space intervals formed between the tines are adjustable.

3. The cleaning apparatus of claim 1 , wherein the expandable assembly comprises:
a plurality of shafts respectively connected to the tines, and a longitudinal axis of each of the tines at least intersects a longitudinal axis of each of the shafts;
a plurality of first connecting rods;
a plurality of second connecting rods, one end of each of the second connecting rods pivotally connected to one end of each of the first connecting rods with one of the shafts;
a plurality of third connecting rods, an intermediate region of each of the third connecting rods pivotally connected to an intermediate region of each of the first connecting rods; and
a plurality of fourth connecting rods, one end of the fourth connecting rods pivotally connected to one end of each of the third connecting rods with another of the shafts, and an intermediate region of each of the fourth connecting rods pivotally connected to an intermediate region of each of the second connecting rods, wherein the adjustment portion connects to the other end of one of the first connecting rods and the other end of one of the third connecting rods,
wherein, when the adjustment portion rotates the first connecting rods, the second connecting rods, the third connecting rods and the fourth connecting rods so that the intermediate regions of the first connecting rods and the intermediate regions of the fourth connecting rods are mutually closed, the expandable assembly reduces the space intervals of the tines.

4. The cleaning apparatus of claim 1 , wherein the expandable assembly comprises an Z-type folded elastic body, two opposite ends of the Z-type folded elastic body are respectively connected to the case and the adjustment portion, and the Z-type folded elastic body comprises a plurality of first sheet body portions and a plurality of second sheet body portions, the first sheet body portions and the second sheet body portions are respectively connected in turn, each of the first sheet body portions and one of the second sheet body portions being adjacently connected to the first sheet body portion respectively form a connecting edge, a longitudinal axis of each of the tines at least intersects a longitudinal axis of each of the connecting edges,
wherein, when the adjustment portion presses the Z-type folded elastic body so that the first sheet body portions and the second sheet body portions are mutually closed, the expandable assembly reduces the space intervals of the tines.

5. The cleaning apparatus of claim 1 , wherein the adjustment portion is a slider block, the slider block is slidably disposed on the case and connected to one end of the expandable assembly for adjusting the space intervals of the tines by controlling the expansion of the expandable assembly.

6. The cleaning apparatus of claim 5 , wherein the tines are equidistantly arranged abreast on the main body, wherein the space intervals of the tines are the same; and
the case is provided with a scale neighboring to the slider block, the scale comprises a plurality of scale values respectively representing different sizes of the space intervals of the tines.

7. The cleaning apparatus of claim 1 , wherein the expandable assembly is resilient, and the adjustment portion is a rotatable screw bolt rotatably disposed on the case and abutted to one end of the expandable assembly for adjusting the space intervals of the tines by pressing the expandable assembly.

8. The cleaning apparatus of claim 7 , wherein the tines are equidistantly arranged abreast on the main body, wherein the space intervals of the tines are the same; and
the rotatable screw bolt is provided with a scale, the scale comprises a plurality of scale values respectively representing different sizes of the space intervals of the tines.

9. The cleaning apparatus of claim 1 , wherein the cleaning head is detachably disposed on the case.

10. The cleaning apparatus of claim 1 , wherein the tines are equidistantly arranged abreast on the main body, wherein the space intervals of the tines are the same.

11. The cleaning apparatus of claim 1 , wherein the tines comprise antistatic material.

12. The cleaning apparatus of claim 1 , wherein each of the tines is in a linear shape, a hook shape, an L type shape or a needle shape.

13. The cleaning apparatus of claim 1 , wherein one distal end of each of the tines is provided with a needle peak portion or a flat panel.
