Abstract

A carrier includes at least one sucking member, a pressure-differentiating device, an optical unit and an image-capturing unit. The at least one sucking member, made of a flexible transparent material, has a plurality of micro holes extending in a first direction by penetrating through two opposing surfaces of the at least one sucking member. The pressure-differentiating device, connected with the at least one sucking member, is to have the at least one sucking member to perform a pressure-differentiated suction upon a workpiece. The optical unit is to capture an image of the workpiece through the at least one sucking member and to refract/reflect the image by an image-forming angle. The image-capturing unit is to capture and further output the image refracted/reflected by the optical unit in a real-time manner.

First claim

What is claimed is:

1 . A carrier, comprising:
at least one sucking member, made of a flexible transparent material, having a plurality of micro holes extending in a first direction by penetrating through two opposing surfaces of the at least one sucking member; a pressure-differentiating device, connected with the sucking member, being to have the sucking member to perform a pressure-differentiated suction upon a workpiece; an optical unit, being to capture an image of the workpiece through the sucking member and to refract/reflect the image by an image-forming angle; and an image-capturing unit, being to capture and further output the image refracted/reflected by the optical unit.

2 . The carrier of claim 1 , wherein the pressure-differentiating device is a vacuum device for having the sucking member to generate a vacuum sucking force upon the workpiece.

3 . The carrier of claim 1 , wherein the optical unit is located at one side of the sucking member opposing to another side for sucking the workpiece.

4 . The carrier of claim 1 , wherein the image-forming angle is 90°.

5 . The carrier of claim 1 , wherein a normal line of the optical unit forms an angle with a surface of the sucking member, and the angle is between 35˜55°.

6 . The carrier of claim 1 , wherein the sucking member is furnished to a housing, the two opposing surfaces are a sucking surface and an image-capturing surface, the sucking surface faces out of the housing, the optical unit and the image-capturing unit are located inside the housing, and a refracting/reflecting surface of the optical unit faces the image-capturing surface so as to capture the image and further refract/reflect the image to the image-capturing unit.

7 . The carrier of claim 6 , wherein the housing includes thereinside a light source for providing luminance inside the housing.

8 . The carrier of claim 1 , wherein the sucking member includes a plurality of the sucking members, each said sucking member having a plurality of micro holes and further including:
a first soft pad, having a through-hole portion extending in the first direction to penetrate two opposing sides of the first soft pad; and a second soft pad, having a protrusive portion protruding in the first direction from a surface of the second soft pad, located at one side of the first soft pad, the protrusive portion penetrating through the through-hole portion and exposing a portion thereof over the first soft pad for sucking and sustaining the workpiece with the first soft pad.

9 . The carrier of claim 1 , wherein the sucking member is a soft pad.

10 . The carrier of claim 8 , wherein the sucking member is a soft pad.

11 . The carrier of claim 1 , wherein the optical unit is one of an optical prism and a spectroscope.

12 . The carrier of claim 1 , wherein the carrier is disposed at a supporting module, and the supporting module is one of a robotic arm, a motion platform and a conveying belt.

13 . The carrier of claim 9 , wherein the soft pad is made of a polydimethylsiloxane (PDMS).

14 . The carrier of claim 10 , wherein the soft pad is made of a polydimethylsiloxane (PDMS).

15 . The carrier of claim 1 , wherein the image-capturing unit is coupled with a calculation module, the calculation module being to receive the image outputted by the image-capturing unit and to perform real-time algorithm analysis upon the workpiece so as to obtain corresponding posture information.
