Abstract

A test base cleaning line and a method thereof are provided. The test base cleaning line includes a plurality of cleaning mechanisms, a scanning device, and a moving device. The scanning device is configured for scanning a barcode on a test base to identify a type of the test base, and the moving device is configured for moving the test base to any one of the plurality of cleaning mechanisms according to the type of the test base so that the cleaning mechanism can perform a cleaning operation to the test base.

Claims (43)

1 . A test base cleaning line, comprising:

a plurality of cleaning mechanisms;

a scanning device configured for scanning a barcode on a test base to identify a type of the test base; and

a moving device configured for moving the test base to any one of the plurality of cleaning mechanisms according to the type of the test base so that the cleaning mechanism performs a cleaning operation on the test base.

2 . The test base cleaning line of claim 1 , wherein the cleaning mechanism comprises an image capturing device, a laser device, and a plurality of storage compartments, wherein the image capturing device is used for capturing an image of the test base, the image is used for confirming a mounting position of a clamp and for confirming a cleaning result, the laser device is used for cleaning the test base, and the plurality of storage compartments are used for storing the cleaned test base.

3 . The test base cleaning line of claim 2 , wherein the moving device further mounts the clamp on the test base according to the image and moves the test base under the laser device, wherein the clamp is removed after the laser device is done cleaning, and the test base is moved to the plurality of storage compartments after the cleaning result is confirmed.

4 . The test base cleaning line of claim 1 , wherein the cleaning mechanism comprises a plurality of cleaning tanks, a high-pressure gas tank, an oven, an image capturing device, and a plurality of storage compartments, wherein the plurality of cleaning tanks are respectively provided with a chemical agent, an alkaline agent, a neutralizing agent, pure water, or alcohol for soaking the test base, the high-pressure gas tank is used for blowing gas to the test base, the oven is used for drying the test base, the image capturing device is used for capturing an image of the test base, the image is used for confirming a cleaning result, and the plurality of storage compartments are used for storing the cleaned test base.

5 . The test base cleaning line of claim 4 , wherein the moving device is further used to first fix the test base on a carrier plate, sequentially put the test base into the plurality of cleaning tanks for cleaning, then put the test base into the high-pressure gas tank for blowing, put the test base into the oven for drying, detach the test base from the carrier plate, and move the test base to the plurality of storage compartments after the cleaning result is confirmed.

6 . The test base cleaning line of claim 1 , wherein the cleaning mechanism comprises an image capturing device, a high-pressure gas tank, and a plurality of storage compartments, wherein the image capturing device is used for capturing an image of the test base, the image is used for confirming a cleaning position of the test base and for confirming a cleaning result, the high-pressure gas tank is used for blowing gas to the test base, and the plurality of storage compartments are used for storing the cleaned test base.

7 . The test base cleaning line of claim 6 , wherein the moving device further cleans the test base with alcohol according to the image, then puts the test base into the high-pressure gas tank for blowing, and moves the test base to the plurality of storage compartments after the cleaning result is confirmed.

8 . The test base cleaning line of claim 1 , wherein the moving device is a robotic arm.

9 . A method for cleaning a test base, comprising:

scanning, by a scanning device, a barcode on the test base to identify a type of the test base; and

moving, by a moving device, the test base to any one of a plurality of cleaning mechanisms according to the type of the test base so that the cleaning mechanism performs a cleaning operation on the test base.

10 . The method of claim 9 , wherein the cleaning operation performed by the cleaning mechanism on the test base comprises:

moving, by the moving device, the test base under a laser device; and

cleaning the test base by the laser device.

11 . The method of claim 10 , wherein the cleaning operation performed by the cleaning mechanism on the test base further comprises:

capturing, by an image capturing device, an image of the test base to confirm a mounting position of a clamp from the image;

mounting, by the moving device, the clamp on the test base according to the image;

moving, by the moving device, the test base under the laser device; and

removing the clamp by the moving device after the laser device is done cleaning.

12 . The method of claim 11 , wherein the cleaning operation performed by the cleaning mechanism on the test base further comprises:

capturing, by the image capturing device, another image of the test base to confirm a cleaning result from the another image; and

moving, by the moving device, the test base to any one of a plurality of storage compartments.

13 . The method of claim 9 , wherein the cleaning operation performed by the cleaning mechanism on the test base comprises:

sequentially putting, by the moving device, the test base into a plurality of cleaning tanks for cleaning, wherein the plurality of cleaning tanks are respectively provided with a chemical agent, an alkaline agent, a neutralizing agent, pure water, or alcohol for soaking the test base;

putting, by the moving device, the test base into a high-pressure gas tank for blowing; and

putting, by the moving device, the test base into an oven for drying.

14 . The method of claim 13 , wherein the cleaning operation performed by the cleaning mechanism on the test base further comprises:

fixing, by the moving device, the test base on a carrier plate;

sequentially putting, by the moving device, the test base into the plurality of cleaning tanks for cleaning; and

detaching, by the moving device, the test base from the carrier plate after the test base is dried in the oven.

15 . The method of claim 14 , wherein the cleaning operation performed by the cleaning mechanism on the test base further comprises:

capturing, by an image capturing device, an image of the test base to confirm a cleaning result from the image after the test base is detached from the carrier plate; and

moving, by the moving device, the test base to any one of a plurality of storage compartments.

16 . The method of claim 9 , wherein the cleaning operation performed by the cleaning mechanism on the test base comprises:

capturing, by an image capturing device, an image of the test base to confirm a cleaning position of the test base from the image;

cleaning the test base with alcohol by the moving device according to the image;
