[0044] Here, the clamping seat 41 includes a seat body 41a and a clamping rod 41b. The seat body 41a is fixedly arranged on the telescopic rod of the clamping cylinder 42, and the clamping rod 41b has an axis perpendicular to the center line of the rotating seat 3 and is adjustably arranged on the seat body 41a along its length direction. Thus, the axial position of the clamping rod 41b can be adjusted according to the thickness of the foam 10 and the working stroke of the clamping cylinder 42, so as to provide stable clamping and fixing of the foam 10.

[0047] In this embodiment, the linear motion direction of the pressing seat 61 is parallel to the linear motion direction of the guiding seat 51, and the foam 10 first passes through the guiding seat 51 and then passes through the pressing seat 61 on the moving path of the foam 10 along the first direction towards the rotating seat 3. That is, the foam 10 is first made to enter the annular groove 201, and then the pressing seat 61 is started to press it, so that the foam 10 can be matched with the annular groove 201 in the radial direction of the workpiece 20.

[0048] The pressing seat 61 further rotatably arranged a rolling member 62 which is parallel to the rotating center line, and the rolling member 62 is fittedly inserted in the annular groove 201 along the height direction. This makes the pressing seat 61 to press the foam 10 by rolling contact through the rolling member 62, the friction is small, and the surface of the foam 10 is not easy to be damaged.

[0050] The guide mechanism 7 further comprises a translation cylinder 72 and a lifting cylinder 73, which are respectively used to drive the guide seat 71 to move towards or away from the rotating seat 3 in the horizontal direction and to move up and down in the vertical direction to match the height position of the workpiece 20.

[0051] The working process of the present embodiment is specifically described as follows:

[0052] The workpiece 20 to be wound with the foam 10 is positioned and installed on the rotating seat 3;

[0053] The foam 10 is fed from the feeding trolley 8, and the carrying member 22 in the feeding mechanism 2 picks up one foam 10 from the feeding trolley 8 and moves it to the guide chute 23. Then, the carrying member 22 keeps clamping the foam 10 and moves in the first direction towards the rotating seat 3;

[0054] The rotating seat 3 rotates by a certain angle, so that the clamping seat 41 of the clamping mechanism 4 is located at the rear side of the guide seat 51 in the first direction;

[0055] The guide seat 51 of the guide mechanism 5 moves linearly towards the rotating seat 3 and cooperates with the workpiece 20, which is clamped in the guide groove of the guide seat 51 in the thickness direction, so that the workpiece 20 and the guide seat 51 cooperatively form a guide channel having a tapered inlet towards the feeding mechanism 2. The foam 10 continues to move towards the rotating seat 3 under the driving of the carrying member 22 and enters the annular groove 201 through the tapered inlet;

[0057] The rotating seat 3 continues to rotate with the foam 10, so that the foam 10 is continuously wound on the workpiece 20. In this process, the pressing seat 61 of the pressing mechanism 6 moves linearly towards the rotating seat 3, so that the pressing seat 61 continuously presses the foam 10 radially inward towards the annular groove 201 at the rear of the guide seat 51, so that the foam 10 can be well matched in the annular groove 201. At the same time, the guide seat 71 of the guide mechanism 7 extends towards the rotating seat 3 to form a guide on the outer circumferential portion of the workpiece 20, so as to avoid the foam 10 from expanding outward from the annular groove 201.

[0058] After the foam 10 is completely wrapped in the annular groove 201 of the workpiece 20, a mechanical hand is used to paste and fix the adhesive tape on the two end portions of the foam 10, so that the automatic winding of the foam 10 on the workpiece 20 is completed. The foam automatic winding machine has a simple structure and can replace manual operation, greatly improving the winding efficiency.
