[0040] In this embodiment, the edge pressing device 6 includes a heat-conducting ring 62 installed at the opening of the edge pressing shell 5, the heat-conducting ring 62 and the shell cavity of the edge pressing shell 5 form an annular cavity 511, the annular cavity 511 is connected to a pump body 63, and the annular surface of the heat-conducting ring 62 is evenly distributed with through holes 621. The annular surface of the heat-conducting ring 62 is also provided with a semiconductor refrigeration ring 66, and the semiconductor refrigeration ring 66 is connected to a power supply 68 through a conductor rod 67. The power supply 68 is provided with a controller 69 for regulating positive and negative electrodes. A carrier ring 61 installed on the heat-conducting ring 62 is provided in the annular cavity 511, and a through hole 611 corresponding to the through hole 621 is provided on the carrier ring 61. The carrier ring 61 is provided with a separation mechanism 64, which includes a ring shell 641 installed on the carrier ring 61, and a through hole 3 6411 corresponding to the through hole 1 611 is provided on the ring shell 641, and a T-shaped rod 642 passes through the through hole 3 6411, and the T-shaped rod 642 is located in the ring shell 641, and one end of the T-shaped rod 642 is connected to the through hole 3 6411 through a spring 643, and a top column sheet 645 is installed at the end of the T-shaped rod 642 away from the ring shell 641, and a ring cavity 2 6412 is formed inside the ring shell 641, and the ring cavity 2 6412 is connected to the pump body 2 65; wherein, the lower end surface of the upper edge pressing device 6 is flush with the lower end surface of the upper mold 131, and the lower edge pressing device 6 is flush with the upper end surface of the lower mold 121; specifically, after the upper mold 131, the SCF steel sheet with glue punching piece with residual glue on the edge to be processed, and the lower mold 121 are completely fitted together, the controller 69 controls the positive and negative electrodes of the power supply 68, so that the end surface of the semiconductor refrigeration ring 66 close to the edge residual glue is the heating surface, and the edge residual glue is subjected to a certain heating and softening treatment. At the same time, the pump body 63 located below pressurizes the ring cavity 511, so that the heat-conducting ring 62 located below is closely attached to the edge of the SCF steel sheet with glue punching piece with residual glue on the edge to be processed and pushed upward until a certain pressure is formed between it and the heat-conducting ring 62 located above, and then The controller 69 controls the positive and negative electrodes of the power supply 68, so that the end surface of the semiconductor refrigeration ring 66 close to one end of the edge residual glue is a cooling surface, and the edge residual glue is subjected to a certain temperature reduction and solidification treatment, so that the edge residual glue of the SCF steel sheet with glue punching part with edge residual glue to be processed can be reshaped, and the edge residual glue thickness of the SCF steel sheet with glue punching part with edge residual glue to be processed is uniform and the shape tends to be regular, which is conducive to the laser released by the laser device 4 to evenly remove the edge residual glue, improve the release accuracy of the laser heat of the laser device 4 to remove the edge residual glue, and further improve the edge residual glue removal quality of the SCF steel sheet with glue punching part with edge residual glue to be processed;When the residual glue at the edge is cooled and solidified, the pump body 1 63 located below reduces the pressure on the ring cavity 1 511, so that the heat-conducting ring 62 located below has a tendency to separate from the lower end surface of the residual glue at the edge. At the same time, the pump body 2 65 located below increases the pressure on the ring cavity 2 6412, so that the top column sheet 645 located below has an upward push effect on the lower end surface of the residual glue at the edge, so that the lower end surface of the residual glue at the edge can be separated from the heat-conducting ring 62 located below more evenly. After the lower heat-conducting ring 62 is separated, the lower pump body 1 63 restores the pressure of the ring cavity 1 511, and the pump body 2 65 restores the pressure of the ring cavity 2 6412.

[0043] In this embodiment, the end surface of the thermal conductive ring 62 away from the ring cavity 511 is provided with a longitudinal groove 622 connected to the through hole 2 621; wherein, after the edge residual glue is heated to soften and cooled to solidify, the processed edge residual glue can have longitudinal ribs that play a reinforcing role, so as to further improve the smoothness of separation between the edge residual glue and the thermal conductive ring 62.

[0044] In this embodiment, the end face of the thermally conductive ring 62 away from the ring cavity 511 is provided with a horizontal groove 623 connected to the through hole 2 621; wherein, after the edge residual glue is heated to soften and cooled to solidify, the processed edge residual glue can have horizontal ribs that play a reinforcing role, so as to further improve the integrity of the separation between the edge residual glue and the thermally conductive ring 62.

[0045] In this embodiment, a non-stick coating 624 is disposed on the end surface of the heat conductive ring 62 away from the ring cavity 1 511 , so as to further enhance the complete separation effect between the edge residual adhesive and the heat conductive ring 62 .

[0049] Step 3: The left and right guide rails 12 control the movement of the lower mold 121 to transport the SCF steel sheet with glue punching parts with edge pressing to the bottom of the laser device 4, and then the front and rear guide rails 11 cooperate to control the laser device 4 to remove the residual glue on the edge of the SCF steel sheet with glue punching parts with edge pressing;

[0050] Step 4: The gas in the process of removing the edge residual glue by the laser device 4 is purified by the purification device 3, and the air in the box cavity of the bellows 31 is sucked by the air pump 34, so that the vaporized edge residual glue processed by the laser device 4 enters the gas purification block 32 through the filter hole 33 for filtration, so that the gas in the space below the laser device 4 is pure, and the vaporized edge residual glue is prevented from adhering to the surface of the SCF steel sheet with glue punching part with processed edge residual glue again, thereby improving the quality of removing the edge residual glue of the SCF steel sheet with glue punching part with processed edge residual glue;

[0051] Step 5: The lower die 121 is controlled to move by the left and right guide rails 12 to convey the SCF steel sheet adhesive punched parts with the residual adhesive on the edges to the left conveying device 2 for output.
