Abstract

Machines for manufacturing photovoltaic modules and methods for manufacturing photovoltaic modules can include tape handling components.

Claims (17)

1. A tape dispensing machine for use in dispensing a tape in manufacturing a photovoltaic module, the machine comprising:

a gripper for gripping a tape and comprising an upper portion and a lower portion, which are movable relative to one another to grip a tape; and

a sensor disposed only within one of the upper portion and the lower portion of the gripper, wherein the sensor is configured to detect a first end of a tape within the gripper.

2. The machine of claim 1 , wherein the gripper is movably mounted to the machine.

3. The machine of claim 1 , wherein the upper portion and the lower portion mate to grip the tape.

4. The machine of claim 3 , wherein the sensor is mounted in the upper portion of the gripper.

5. The machine of claim 3 , wherein the sensor is mounted in the lower portion of the gripper.

6. The machine of claim 1 , further comprising a tape graspable by the gripper, wherein the tape comprises tin-plated copper.

7. The machine of claim 1 , wherein the sensor is a fiber optic sensor.

8. The machine of claim 1 , further comprising a tape source rotatably mounted to the machine.

9. The machine of claim 1 , further comprising a stationary gripper mounted to the machine and positioned between the gripper and the tape source.

10. The machine of claim 9 , further comprising a tape cutter mounted to the machine and positioned between the gripper and the stationary gripper.

11. The machine of claim 1 further comprising a warning system mounted to the machine and connected to the sensor.

12. The machine of claim 1 , further comprising a second sensor disposed within the gripper and laterally of the sensor to detect the tape within the gripper, wherein the second sensor is mounted in the same one of the upper portion and the lower portion as the sensor and both the sensor and the second sensor are directed toward the other of the upper portion and the lower portion.

13. The machine of claim 9 , further comprising a second sensor disposed within the stationary gripper to detect the tape within the stationary gripper.

14. The machine of claim 12 , wherein respective signals from the sensor and the second sensor indicate slippage of a tape held in the gripper.

15. The machine of claim 1 , wherein the sensor is a Hall effect sensor.
