Then, the lifting driving pieces 11 of all the turnover edge covering mechanisms 30 distributed in an array along the long straight edge 201 and the short straight edge 202 extend out to drive all the corresponding turnover edge covering mechanisms 30 to press downwards, and the pressing bottom plate 12 presses the skin 3, so that the skin cannot move or bulge when being turned over.

Then, the horizontal edge searching driving part 21 retracts to drive the inclined edge searching driving part 24 and other parts on the inclined edge searching driving part to move horizontally, at the moment, the edge searching bottom plate 22 presses the skin 3 corresponding to the long straight edge 201 and the short straight edge 202 to the inner edge of the frame 2 inclined by 15 degrees, and the bending plate 32 is horizontally pulled to contact the edges of the skin 3 corresponding to the long straight edge 201 and the short straight edge 202 and slide on the edge of the skin 3; after the horizontal edge searching driving part 21 stops retracting, the inclined edge searching driving part 24 extends out to drive the part connected with the horizontal edge searching driving part to move along the direction which is 15 degrees with the horizontal direction, at the moment, the bending plate 32 is continuously pulled, the skin 3 edge corresponding to the long straight edge 201 and the short straight edge 202 slides, the edge of the skin 3 is pressed by the bending plate 32 and then deforms and bends downwards, as shown in fig. 9 and 10, at the moment, the edge covering equipment 1 is in the first state.

Referring to fig. 11 and 12, the first bending driving element 311 extends to drive the connecting bottom plate 312, and the second bending driving element 313 and the bending plate 32 thereon to rotate for the first time, and the inclined edge-finding driving element 24 retracts and adjusts properly under the action of a force during the rotation process, so that the bending plate 32 always abuts against the covering edges of the skin 3 and the frame 2 corresponding to the long straight edge 201 and the short straight edge 202, and at the same time, the bending plate 32 can rotate normally, and after the bending plate rotates for a certain angle, the first bending driving element 311 does not reach the maximum extending stroke, and is influenced by the structure of the bending plate 32, the hinge part 221 is pressed on the skin 3, as shown in fig. 12, and at this time, the covering device 1 is in the second state.

Then, referring to fig. 13 and 14, the inclined edge finding driving member 24 retracts to drive the component connected thereto to move down along the inclination of 15 °, the skin 3 is loosened by the bending plate 32, the first bending driving member 311 reaches the maximum extending stroke, the bending plate 32 continues to rotate by a certain angle, and at this time, the edge covering device 1 is in the third state.

Referring to fig. 15 and 16, the second bending driving member 313 extends out to drive the bending plate 32 to rotate continuously, the bending plate 32 continues to contact and slide on the edge of the skin 3 bent at a certain angle, the edge of the skin 3 continues to be bent and deformed under the support of the inner edge of the frame 2, and finally the bending plate 32 is pressed under the inner edges of the skin 3 and the frame 2, and at this time, the hemming device 1 is in a fourth state.

Under the state that the bending plates 32 of the turnover edge covering mechanisms 30 corresponding to the long straight edge 201 and the short straight edge 202 are continuously compressed, the lifting driving pieces 11 of the turnover edge covering mechanisms 30 corresponding to the four corner edges 203 extend out to drive the four compression bottom plates 12 to be pressed downwards, then the horizontal edge searching driving pieces 21 of the turnover edge covering mechanisms 30 of the four corner edges 203 retract, the inclined edge searching driving pieces 24 extend out to drive the bending plates 32 to bend the skins 3 corresponding to the corner edges 203 for one time, then the first bending driving pieces 311 extend out to drive the bending plates 32 to rotate the skins 3 corresponding to the corner edges 203 to bend for two times, at the moment, the skins 3 corresponding to the corner edges 203 and the double-layer structures formed by the turnover edge folding of the straight edges form turnover with a certain angle, then the first bending driving pieces 311 of the turnover edge covering mechanisms 30 of the corner edges 203 retract, the bending plates 32 corresponding to the corner edges 203 loosen the skins 3, and the first bending driving pieces 311 and the second bending driving pieces 313 of all the turnover edge covering mechanisms 30 of the long straight edge 201 and the short straight edge 202 retract, the horizontal edge finding driving piece extends out.

Then, the turnover edge covering mechanisms 30 corresponding to all the corner edges 203 continue to complete the turnover of the skins 3 of the four corner edges 203 according to the edge covering action of the turnover edge covering mechanisms 30 corresponding to the previous long straight edge 201 and short straight edge 202 (i.e., the skins 3 corresponding to the corner edges 203 extend from the first bending driving piece 311 to the second bending driving piece 313), after the skins 3 are turned and formed, the first bending driving piece 311 and the second bending driving piece 313 of the turnover edge covering mechanisms 30 corresponding to the four corner edges 203 retract, the horizontal edge searching driving piece 21 extends out, finally, the lifting driving pieces 11 of all the turnover edge covering mechanisms 30 retract, and the edge searching mechanism 20 and the turnover edge covering mechanisms 30 are lifted.

To this end, one working cycle of the entire hemming apparatus 1 is completed, and the movable assembly platform 300 transfers the upper frame 2 (finished product) having completed the hemming to the next production station.

In the above embodiment, since the bending of the covering 3 by the hemming device 100 is performed by dividing into three angles, it is convenient to adjust the three angles, so that the hemming operation is refined. It can be understood that the turnover covering mechanism 30 can also be a structure of a mechanical arm tool head, and can be used for bending the skin 3 in a multi-stage and multi-angle mode.
