Abstract

A suction head including a first transmission part, a second transmission part and a suction nozzle is provided. The second transmission part is magnetically attracted by the first transmission part to permit a displacement of the second transmission part relative to the first transmission part. The suction nozzle is disposed on the second transmission part and transmitted by the first transmission part via the second transmission part. Additionally, a transporting machine including a shuttle, a transporting mechanism and the aforementioned suction nozzle is provided. The shuttle is capable of carrying an object being transported, and the suction head is driven by the transporting mechanism to take the object being transported. The suction head and the transporting machine applying the same provide high transporting efficiency and ensuring a normal operation in transporting process.

Claims

1. A suction head, comprising:

a first transmission part;

a second transmission part, magnetically attracted by the first transmission part to permit a displacement of the second transmission part relative to the first transmission part;

a partition plate disposed at an attraction interface between the first transmission part and the second transmission part; and

a suction nozzle, disposed on the second transmission part and transmitted by the first transmission part via the second transmission part.

2. The suction head as claimed in claim 1, wherein the first transmission part comprises:

a first transmission shaft; and

a first magnet disposed at an end of the first transmission shaft and attracting the second transmission part.

3. The suction head as claimed in claim 1, wherein the second transmission part comprises:

a second transmission shaft; and

a second magnet disposed at an end of the second transmission shaft and attracting the first transmission part.

4. The suction head as claimed in claim 3, wherein the second transmission part further comprises a joint communicating with the suction nozzle.

5. The suction head as claimed in claim 1, further comprising a guider having an outline complying with a shuttle carrying an object being transported.

6. The suction head as claimed in claim 5, wherein the guider is provided with an outer inclined plane complying with a cavity of the shuttle, the cavity accommodating the transported object.

7. The suction head as claimed in claim 5, wherein the guider is provided with an inner inclined plane surrounding the suction nozzle and leaning against the object attracted by the suction nozzle.

8. The suction head as claimed in claim 5, wherein the guider is provided with at least a through hole having a profile complying with a guide pin on the shuttle.

9. The suction head as claimed in claim 1, wherein the suction nozzle is retractable.

10. A transporting machine, comprising:

a shuttle carrying an object being transported;

a transporting mechanism;

a suction head driven by the transporting mechanism, the suction head comprising;

a first transmission part connected to the transporting mechanism;

a second transmission part, magnetically attracted by the first transmission part to permit a displacement of the second transmission part relative to the first transmission part;

a partition plate disposed at an attraction interface between the first transmission part and the second transmission part; and

a suction nozzle, disposed on the second transmission part and transmitted by the first transmission part via the second transmission part.

11. The transporting machine as claimed in claim 10, wherein the first transmission part comprises:

a first transmission shaft; and

a first magnet disposed at an end of the first transmission shaft and attracting the second transmission part.

12. The transporting machine as claimed in claim 10, wherein the second transmission part comprises:

a second transmission shaft; and

a second magnet disposed at an end of the second transmission shaft and attracting the first transmission part.

13. The transporting machine as claimed in claim 12, wherein the second transmission part further comprises a joint communicating with the suction nozzle.

14. The transporting machine as claimed in claim 10, wherein the suction head further comprises a guider having an outline complying with the shuttle.

15. The transporting machine as claimed in claim 14, wherein the guider is provided with an outer inclined plane complying with a cavity of the shuttle, the cavity accommodating the transported object.

16. The transporting machine as claimed in claim 14, wherein the guider is provided with an inner inclined plane surrounding the suction nozzle and leaning against the object attracted by the suction nozzle.

17. The transporting machine as claimed in claim 14, wherein the guider is provided with at least a through hole having a profile complying with a guide pin on the shuttle.

18. The transporting machine as claimed in claim 10, wherein the suction nozzle is retractable.

19. A suction head, comprising:

a first transmission shaft having a first vertical longitudinal axis;

a first magnet disposed at an end of the first transmission shaft;

a second transmission shaft having a second vertical longitudinal axis;

a second magnet disposed at an end of the second transmission shaft;

a horizontal partition plate disposed between the first magnet and the second magnet, wherein the first magnet and the second magnet are attracted to each other with the horizontal partition plate therebetween, to permit a displacement of the second magnet relative to the first magnet;

a retractable suction nozzle disposed at another end of the second transmission shaft and transmitted by the first transmission shaft via the second transmission shaft;

a joint disposed on the second transmission shaft and communicating with the suction nozzle; and

a guider having an outline complying with a shuttle carrying an object being transported.
