Moulding/demoulding device for battery cover film on battery assembling line

The utility model relates to a battery die sleeve access device in the battery assembly line, which comprises a device for die sleeve entering, a depanning device and barriers, wherein the device for die sleeve entering and the depanning device is separately provided with power shafts, the two-double thumbwheels with upper and lower thumbwheels which are immovably connected with the power shafts, the feeler wheel fixed in the power shaft by the bearing, the backform device which is sleeved in the outer column surface of the feeler wheel and moves along the feeler wheel curve. The feeler wheel curve of the device for die sleeve entering is opposite to the feeler wheel curve of the depanning device and the two feeler wheel curves configures symmetrically. The device employs the feeler wheel enforcement mandril which can slide up and down to complete the die sleeve entering. The depanning device adds an enforcement separation small profile modeling block for reliable work and low failure rate. The utility model has the advantages of simple structure, easy to achieve, not high precision requirement, lower manufacturing cost, small structure size, convenient to be arranged on the surface of the stand-alone, space saving and is be suitable for the batteries with different specifications.
