In the process of the support plate 522 moving upward, the heating box squeezes the cushion 12 to move upward, so that the inner pad layer is abutted against the sole. At this time, the second heating block 525 and the third liquid pump 529 are controlled to work, and the glue in the second glue box 528 is pumped to the inside of the heating box. At the same time, the micro needle 527 pierces the cushion 12 and inserts into the inner pad layer to achieve local enhanced pressing. In this process, the pressure inside the heating box increases, and the glue is squeezed from the middle of the micro needle 527 to the inner pad layer and the contact position between the inner pad layer and the sole. Ensure that each contact point between the inner pad layer and the sole is fully bonded, further improving the fixing effect. At the same time, the micro needle 527 is heated as a whole by the heat conducting block 530 to avoid the glue solidification when production is not carried out, and the glue in the micro needle 527 cannot flow back.

[0070] The method of using the insole inner pad bonding and pressing device of the present invention is as follows: first, control the first servo motor 9 to work and drive the first lead screw 8 to rotate. At this time, the first guide rod 10 moves in the first slide rail, thereby extending the processing frame 2 outward from the equipment cabin 1. When the processing frame 2 moves, the pulley 14 is used to reduce the resistance. Then the inner pad is placed on the cushion 12. Control the first liquid pump 50 to work and pump the glue in the first glue box 48 to the glue-coated plate 41. The glue on the glue-coated plate 41 flows back to the inside of the first glue box 48 through the reflux chamber 47. In this process, the glue-coated cotton 46 contacts with the glue, and at the same time, the first heating block 49 can be controlled to work to maintain the appropriate temperature of the glue, promote the fluidity and viscosity of the glue, ensure that the glue plays a full role in the bonding process, and improve the bonding strength.

[0071] The second servo motor 428 is controlled to work and drive the second lead screw 427 to rotate. At this time, the upper pressing plate 422 slides in the second guide rail 421, thereby driving the smear plate 425 to move toward the processing frame 2. In this process, the glue-coating cotton 46 rolls to apply glue to the smear plate 425. When the upper pressing plate 422 moves above the processing plate 3, the first telescopic rod 424 is controlled to unfold and the smear plate 425 is moved downward, so that the glue is applied to the inner cushion layer. In this process, the positioning pin 13 is inserted into the interior of the first positioning hole 423 for positioning. When the upper pressing plate 422 moves, it drives the plug plate 431 to move synchronously. When the upper pressing plate 422 moves above the processing plate 3, the plug plate 431 is inserted into the processing cavity 44. When the smear plate 425 descends, the airbag 432 is synchronously controlled to expand to squeeze the cushion 12, thereby assisting the smear plate 425 in the glue application work. After the glue is applied, the first telescopic rod 424 is controlled to extend, and the air pump 429 is controlled to work at the same time to separate the inner cushion layer from the smear plate 425 to prevent the inner cushion layer from sticking to the smear plate 425 and causing displacement. When the first telescopic rod 424 is working, it is guided by the positioning rod 426. Then the second servo motor 428 is controlled to reverse and the upper pressing plate 422 is returned to the equipment cabin 1. At this time, the smear plate 425 is in contact with the glue-coated cotton 46 and glue is applied again. The airbag 432 is controlled to shrink synchronously, and the plug plate 431 is returned to the interior of the equipment cabin 1 with the movement of the upper pressing plate 422.

[0072] Afterwards, the second telescopic rod 517 is controlled to extend, and the sole is placed below the sole mold 512 to abut against the fitting pad 513. The second telescopic rod 517 is controlled to contract, and the extrusion plate 511 drives the sole mold 512 to move downward. The sole is made to abut against the inner pad layer, and in this process, the positioning pin 13 is inserted into the second positioning hole 514 for positioning. The second liquid pump 516 is controlled to work, and the liquid is pumped to the inside of the sole mold 512, so that the sole is squeezed through the fitting pad 513, and the inner pad layer and the sole are pressed. When the second telescopic rod 517 is contracted, the third telescopic rod 521 is controlled to extend, so that the support plate 522 is moved upward, and in this process, the fourth telescopic rod 523 is used for auxiliary support and guidance. In the process of the support plate 522 moving upward, the heating box squeezes the soft pad 12 to move upward, so that the inner pad layer is abutted against the sole. At this time, the second heating block 525 and the third liquid pump 529 are controlled to work, and the glue in the second glue box 528 is pumped to the inside of the heating box. At the same time, the microneedle 527 pierces the cushion 12 and inserts into the inner pad layer to achieve local enhanced pressing. In this process, the pressure inside the heating box increases, and the glue is squeezed from the middle of the microneedle 527 into the inner pad layer and the contact position between the inner pad layer and the sole. Ensure that each contact point between the inner pad layer and the sole is fully bonded, further improving the fixing effect. At the same time, the microneedle 527 is heated as a whole by the heat conducting block 530 to avoid the glue solidification when production is not carried out, and the glue in the microneedle 527 cannot flow back.
