In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.

the offset gravity roller 3 comprises a cylindrical roller body 31, a weight mounting grid 34 is arranged in the roller body 31, a counterweight 35 is mounted on the weight mounting grid 34, and a side cover 33 is mounted on the side edge of the roller body 31 through a screw 32. The autorotation gravity device is made of nonmetal PP materials and is of a breaking type, the autorotation gravity device is only contacted with two ends of a COF substrate when in operation, and an internal pattern circuit area is non-contact, so that contact type scratches and friction injuries are effectively avoided. Preferably, the internal width of the offset gravity roller 3 is 158mm, the width of the offset position is 2mm, the height is 2mm, and in addition, in order to avoid the sharp right angle from causing injury to the user and the product, the outermost extension of the offset gravity roller 3 needs chamfering treatment.
As an improvement of the embodiment, the supporting limit plate 1 is L-shaped, the offset gravity roller 3 rolls up and down along the supporting limit plate 1 through the bearing 2, and the direction and the path are provided for the up-and-down movement of the offset gravity roller through the supporting limit plate 1.
As the improvement of the embodiment, the supporting limit plate 1 is adsorbed on the side wall of the machine through the magnetic strip, and additional machining and machine transformation are not needed.
As the improvement of embodiment, bearing 2 adopts PP or PVC material, support limiting plate 1 and adopt the PVC material, when bearing 2 along supporting limiting plate 1 rolling friction, can not have foreign matter dregs to produce.
The counterweight of the autorotation gravity device can be changed, and the required downforce is different along with the different thicknesses of COF substrates (the copper thicknesses and PI thicknesses of COF substrates of different models are different) and the different contact surfaces of the COF substrates and machines, so the gravity of the offset gravity roller can be correspondingly changed according to the different downforce. The internal cavity of the autorotation gravity device is hollow and is provided with the weight mounting grids 34, and the weight of the autorotation gravity device can be increased or decreased by increasing or decreasing the counterweight, so that the down force when the COF substrate is wound is changed. Preferably, the counterweight 35 is cylindrical, the counterweight 35 comprises three specifications of 10 g/piece, 20 g/piece and 50 g/piece, corresponding counterweights can be added or reduced according to the required weight, and the use is convenient.
Finally, as shown in fig. 5, the present invention further provides a method for using the self-rotation gravity device, comprising the steps of: when a product runs on the alignment CCD camera 4 and the product adsorption workbench 5 and the autorotation gravity device descends to reach the position of the lower limit sensor 7, the lower limit sensor 7 captures a signal, and the signal is transmitted to the controller to control the coiling end to start coiling operation; when the autorotation gravity device reaches the position of the upper limit sensor 6, a signal is captured by the upper limit sensor 6 and is transmitted to the controller to control the coiling disc to stop coiling; and the autorotation gravity device descends to the position of the lower limit sensor 7 along with the operation of the product, and repeatedly moves between the positions of the upper limit sensor 6 and the lower limit sensor 7.
Example 1
As shown in fig. 5, when a product runs on the alignment CCD camera 4 and the product adsorption worktable 5 and the autorotation gravity device descends to the position of the lower limit sensor 7, the lower limit sensor 7 captures a signal, and the signal is transmitted to the controller to control the winding end to start the winding operation;

Under the action of the rotation gravity device, the COF substrate is always pulled downwards by the gravity of the rotation gravity device, and due to the influence of the pull-down force, two sides of the substrate are naturally smooth and tangent to a cylinder of the rotation gravity device. Thus, the coil was completely free from fluffs and wrinkles at the time of winding.
The method can prevent the COF substrate from being fluffy and wrinkled during winding, ensure the tightness and firmness of the wound product, improve the production efficiency, avoid bad waste and improve the quality.
