[0037] A method for automatically unwinding and joining sheet material coils, the method being implemented by the following steps: Step 1. Install the sheet coiling mandrel onto the station of the driving mandrel, with the foil head of the sheet coil in a drooping position.

[0038] Step 2. Determine the foil head position of the sheet coil.

[0039] The purpose of the foil head of the sheet material coil being in a drooping posture is to facilitate pulling into the riveting station, and the edge of the foil head in the drooping posture can be measured by the induction probe.

[0040] Step 3. Based on the position of the foil head of the sheet coil determined in step 2, the foil head clamping mechanism moves to the foil head clamping position of the sheet coil and clamps the foil head of the sheet coil. The foil head clamping mechanism sends the foil head of the sheet coil to the riveting station.

[0041] Step 4. The foil head of the sheet coil on the riveting material station is floated and pressed, and the sheet coil mandrel is reversed to withdraw the foil head of the sheet coil sent to the riveting material station to the standard riveting material position.

[0042] Since the foil head clamping mechanism clamps part of the foil head, after the foil head clamping mechanism releases the foil head, the sheet coiling mandrel reverses to move the foil head to a correct riveting position.

[0043] Step 5. Use a riveting piece to rivet the foil head of the sheet coil and the tail of the discharge end into one piece.

[0044] Step 6. After the coil is laid out, cut the tail of the material.

[0045] One side of the riveted connecting piece overlaps the head of the foil sheet of this loading, and the other side overlaps the tail of the previous material. The riveted head rivets the head and tail of the riveted connecting piece foil sheet into one. The cutting tail separates the material from the mandrel.
