The sheet conveying mechanism 100 comprises a vacuum chuck group 110 which is used for being communicated with an external vacuum pump and grabbing sheets, and an X-axis driving assembly 120 which is fixedly connected with the vacuum chuck group 110 and drives the vacuum chuck group 110 to move along the horizontal direction, wherein a vacuum grabbing area is formed below the vacuum chuck group 110, one side of the X-axis driving assembly 120 is a feeding end, and the other side of the X-axis driving assembly 120 is a receiving end. The feeding box 200 is arranged at the feeding end and can be lifted in the vertical direction to feed the vacuum chuck group 110; the receiving bin 300 is disposed at the receiving end and can be lifted in a vertical direction to receive the sheet material conveyed by the vacuum chuck group 110.

The winding head mechanism 500 is located between the feeding box 200 and the receiving box 300 and is arranged at intervals with the X-axis driving assembly 120, a material receiving/positioning station and a winding station are sequentially arranged between the X-axis driving assembly 120 and the winding head mechanism 500, and the winding head mechanism 500 is used for conducting winding operation on the sheet so as to wind copper wires on the sheet. The Y-axis drive assembly 600 is coupled to the winding platform 400 and drives the winding platform 400 to move between the material receiving/positioning station 101 and the winding station 102 to receive and position the sheet material and to wind the sheet material. In this embodiment, the winding platform 400 is used for collecting the sheet to be wound and positioning the sheet when in the material receiving/positioning station 101; the winding station 400 winds the sheet material at the winding station 102 by a winding head configuration.

Specifically, referring to fig. 1-6, during operation of the winding machine, the X-axis driving assembly 120 first drives the vacuum chuck set 110 to move to the feeding end until the vacuum chuck set 110 is above the feeding box 200, and then the feeding box 200 is lifted up, so that the sheets in the feeding box 200 enter the grabbing range of the vacuum chuck set 110, i.e. the sheets enter the vacuum grabbing area. In this case, the vacuum chuck assembly 110 is turned on to the external vacuum pump so that a negative pressure is formed at the vacuum grip area, and thus, the sheet material in the feed box 200 exits the feed box 200 under the negative pressure and is sucked on the vacuum chuck assembly 110. Subsequently, the X-axis driving assembly 120 drives the vacuum chuck assembly 110 to move to the receiving/positioning station 101 in a direction approaching the receiving bin 300, and at the same time, the Y-axis driving assembly 600 drives the winding platform 400 to move to the receiving/positioning station 101, the vacuum chuck assembly 110 is disconnected from the external vacuum pump, and the sheet falls on the winding platform 400 under the action of self weight.

Due to the limited maximum distance between the feeding bin 200 and the receiving bin 300, as the number of sheets in the feeding bin 200 decreases, it may happen that the sheets are outside the vacuum gripping area of the vacuum chuck group 110 when the feeding bin 200 is raised to the maximum height, in which case the mounting plate 111 may be driven by the first cylinder 114 to descend so that the sheets enter the vacuum gripping area, thereby facilitating gripping of the sheets from the feeding bin 200.
