Abstract

A powder gathering apparatus includes at least two rotating plates and a driving mechanism. The at least two rotating plates are disposed with respect to each other. Each of the rotating plates includes at least one spherical member. The at least one spherical member protrudes from the rotating plate. The driving mechanism drives at least one of the at least two rotating plates to move, such that the at least two rotating plates get close to or away from each other. The driving mechanism drives the at least two rotating plates to rotate.

First claim

What is claimed is:

1. A powder gathering apparatus comprising:
at least two rotating plates disposed with respect to each other, each of the rotating plates comprising two plate bodies, a plurality of rails and a plurality of spherical members, the spherical members being rotatably sandwiched in between the two plate bodies and protruding from the rotating plate, each of the rails comprising at least one of the spherical members, the rails being concentric and circular rails with different sizes and arranged from inside to outside;
a driving mechanism driving at least one of the at least two rotating plates to move, such that the at least two rotating plates get close to or away from each other, the driving mechanism driving the at least two rotating plates to rotate;
a powder container disposed below a prepreg or a copper-free laminate between the at least two rotating plates; and
a sieve disposed in the powder container, the sieve being located directly below and parallel to the at least two rotating plates.

2. The powder gathering apparatus of claim 1 , wherein a rotating shaft of each rotating plate is perpendicular to a plane when the powder gathering apparatus is disposed on the plane.

3. The powder gathering apparatus of claim 1 , further comprising at least two support bases, the at least two support bases being disposed with respect to each other, each of the rotating plates being disposed on one of the at least two support bases.

4. The powder gathering apparatus of claim 1 , wherein each of the rotating plates comprises at least one fixing member and the at least one fixing member fixes the at least one spherical member on the rotating plate.

5. The powder gathering apparatus of claim 1 , wherein the driving mechanism drives each of the rails to rotate clockwise.

6. The powder gathering apparatus of claim 5 , wherein rotating directions of the rails are identical.

7. The powder gathering apparatus of claim 5 , wherein rotating directions of the rails are different.

8. The powder gathering apparatus of claim 1 , wherein the driving mechanism drives each of the rails to rotate counterclockwise.

9. The powder gathering apparatus of claim 8 , wherein rotating directions of the rails are identical.

10. The powder gathering apparatus of claim 8 , wherein rotating directions of the rails are different.

11. The powder gathering apparatus of claim 1 , wherein the rails of the at least two rotating plates correspond to or are staggered with each other.

12. The powder gathering apparatus of claim 1 , wherein the driving mechanism comprises a plurality of rollers and each of the rails is driven to rotate by at least two of the rollers.

13. The powder gathering apparatus of claim 1 , wherein a material of the at least one spherical member is stainless steel, iron or zirconia.

14. The powder gathering apparatus of claim 1 , configured to gather powders from the prepreg or the copper free laminate.

15. The powder gathering apparatus of claim 1 , further comprising a hanging mechanism, the hanging mechanism being configured to hang the prepreg or the copper-free laminate between the at least two rotating plates.

16. The powder gathering apparatus of claim 1 , further comprising an air drawing mechanism, the air drawing mechanism being disposed in the powder container.
