Mask management method and bar code reading apparatus thereof
View Patent ↗A mask management and bar code reading apparatus thereof are disclosed. The mask management method comprises providing a bar code reading apparatus, scanning a mask bar code on the mask by the bar code reading apparatus, transferring scanned information to a mask management system, producing a box bar code, moving the mask to a mask pod from a mask protective case, sticking the box bar code on the mask pod, inputting the data recorded in the box bar code into an exposure equipment, and exposing the mask by the exposure equipment. The bar code reading apparatus includes at least a clamping element to clamp the mask protective case, at least a reading head disposed on the clamping element to read a mask bar code, and a first light source providing a first light to irradiate the mask protective case to increase reading accuracy of the reading head.
1. A bar code reading apparatus, reading a mask bar code on a mask in a mask protective case, comprising:
at least a clamping element, clamping the mask protective case;
at least a reading head disposed corresponding to the mask protective case and reading a mask bar code;
a base, supporting the mask protective case;
a first rod connected to the base;
a second rod connecting the reading head and the first rod; and
a first light source, disposed in the base, providing a first light to irradiate the mask protective case.
2. The bar code reading apparatus as claimed in claim 1 , wherein the first light emitted by the first light source irradiates the mask protective case from bottom to top.
3. The bar code reading apparatus as claimed in claim 1 , further comprising a second light source, emitting a second light irradiating the mask protective case from top to bottom.
4. The bar code reading apparatus as claimed in claim 1 , wherein the first light source modulates colors of the first light with respect to different materials, transmittance, colors of the mask protective case.
5. The bar code reading apparatus as claimed in claim 1 , wherein the first light source comprises light emitting diode.
6. The bar code reading apparatus as claimed in claim 1 , wherein the reading head moves in a direction parallel to a surface of the mask bar code, modifying an adequate reading position.
7. The bar code reading apparatus as claimed in claim 1 , wherein the reading head moves in a direction perpendicular to a surface of the mask bar code, modifying focal length thereof.
8. The bar code reading apparatus as claimed in claim 1 , wherein the reading head rotates in a direction parallel to a surface of the mask bar code for different reading positions.
9. The bar code reading apparatus as claimed in claim 1 further comprising a reflective mirror, disposed in the base, reflecting the first light to the mask bar code.
10. The bar code reading apparatus as claimed in claim 1 , wherein the reading head reads linear bar codes and two-dimensional bar codes.
11. A mask management method, comprising:
providing a bar code reading apparatus;
scanning a mask bar code on the mask in a mask protective case by the bar code reading apparatus;
producing a box bar code according to scanned information from the bar code reading apparatus;
moving the mask to a mask pod; and
sticking the box bar code on the mask pod.
12. The mask management method as claimed in claim 11 , wherein the bar code reading apparatus increases reading accuracy by a first light emitted by a first light source, irradiating at the mask protective case.
13. The mask management method as claimed in claim 12 , wherein when the mask protective case is red, the first light comprises red light.
14. The mask management method as claimed in claim 12 , wherein when the mask protective case is blue, the first light comprises blue light.
15. The mask management method as claimed in claim 12 , wherein when the mask protective case is colorless, the first light comprises white light.
16. The mask management method as claimed in claim 11 , further comprising transferring the scanned information from the bar code reading apparatus into a mask management system, and automatically printing the box bar code.
17. A bar code reading apparatus, comprising:
a base, supporting a mask protective case;
a clamping element, disposed on the base to position the mask protective case;
a first rod, comprising an end connected to the base;
a second rod, comprising an end connected to the other end of the first rod;
a reading head, disposed above the base and connected to the other end of the second rod to read a mask bar code on the mask protective case from top to bottom; and
a first light source, disposed in the base to provide a first light irradiating from the bottom of the mask protective case to top.
18. The bar code apparatus as claimed in claim 17 , further comprising a connecting head, connecting the first rod and the second rod.
19. The bar code apparatus as claimed in claim 17 , further comprising a second light source, emitting a second light irradiating the mask protective case from top to bottom to increase reading ability.
20. The bar code apparatus as claimed in claim 17 , wherein the first light source is disposed on a side of the base, and the bar code apparatus further comprises a reflective mirror disposed in the base reflecting the first light to the mask bar code.
21. The bar code apparatus as claimed in claim 17 , wherein the clamping element is disposed on the base with an L-shape corresponding to the shape of the mask protective case.
