Description

TECHNICAL FIELD

The winding roller 2 is positioned above the winding platform 1, with its axis at a height h from the winding platform 1. This height h provides a variable range for the diameter of the winding roller 2 to increase during the winding process, until it contacts the surface of the winding platform 1 at its maximum diameter. The adaptive moving device 4 is positioned in front of the winding platform 1 and is used to grip the driven roller 3, driving the driven roller 3 to move back and forth and up and down. According to an adaptive algorithm, the driven roller 3 adaptively conforms to the surface of the winding roller 2, ensuring the compactness of the winding.

[0031] The coil platform 1 has a long, narrow groove 11 in the middle. The groove is semi-circular, and the size of the arc surface matches that of the driven roller 3. The groove 11 is used to fix the driven roller 3 in the initial state of the coil.

[0034] The Y-axis moving mechanism 43 is fixedly installed on the support 423 and moves forward and backward with the support 423. The Y-axis moving mechanism 43 comprises a Y-axis driving cylinder 431 and a fixed part 432. The Y-axis driving cylinder 431 is fixedly installed on the support 423, and the output end is fixedly connected with the fixed part 432 below the support 423. The Y-axis driving cylinder 431 drives the fixed part 432 to move up and down in the Y-axis direction through the extension and contraction.

[0035] The clamping mechanism 44 is fixedly installed on the fixed part 432 and moves up and down with the fixed part 432.

The clamping cylinder 441 is fixedly installed on the fixed part 432, and the left and right output ends of the clamping cylinder 441 are fixedly connected with the two clamping arms 442 respectively. The clamping cylinder 441 drives the two clamping arms 442 to approach or move away through the extension and contraction, so as to realize the clamping or loosening action. The clamping arms 442 are used for clamping the driven roller 3.

[0036] Further, the material winding roller 2 and the driven roller 3 are both provided with elastic mechanisms, which can adopt a pneumatic adjustable elastic structure. The pneumatic elastic structure adopts a slide table cylinder mode, and the elastic force is adjusted by adjusting the air pressure, so as to realize the error compensation.

[0037] As shown in Figure 2 A variable-diameter self-adaptive material winding method with circular arc interpolation of the present application comprises a front end fitting step and a material winding step, which are as follows:

[0038] Step 1: front end fitting step

[0039] Step 1.1, as shown in Figure 3 , the driven roller 3 is placed in the groove 11 of the material winding platform 1, and then the material to be wound is placed on the material winding platform 1 and covers the driven roller 3, leaving a length in front;

[0042] Step 1.4: The adaptive moving device 4 calculates the corresponding arc path according to the diameter of the roll roller 2, and realizes arc interpolation through the motion controller to achieve close contact between the driven roller 3 and the roll roller 2 in the initial state.

[0043] Step 2: Coil Steps:

[0044] Step 2.1: By calculating the material thickness, set the diameter change value T for each turn during the winding process, and increase the number of rotations C by 1 for each rotation of the winding roller 2, and increase the Y-axis height G by 2C*T, so as to achieve real-time contact between the driven roller 3 and the winding roller 2.

[0045] Step 2.2, as follows Figure 5 As shown, after the driven roller 3 and the winding roller 2 are bonded at the front end of the material, the driven roller 3 moves to the winding position D. At this time, the winding roller 2 rotates to wind the material, and as the number of winding layers increases, the driven roller 3 shifts its position; thus, the driven roller 3 and the winding roller 2 maintain close contact as their diameters continuously increase during the winding process.
