[0024] See also Figure 6 , a ball 509 is embedded at the top of the support rod 508. The ball 509 abuts against the inner wall of the extrusion block 505.

[0026] The working principle of the first embodiment of the present invention is as follows: See also Figure 1 Before using the copper pressing machine to press the copper foil, the lower copper foil roll is first placed on the lower copper foil roller 201, and one end of the lower copper foil roll passes through the lower copper foil receiving platform 202 and the pressing structure 5 in sequence; the dry film is placed on the dry film roller 301, and one end of the dry film passes through the dry film receiving platform 302 and the pressing structure 5 in sequence, and the film on both sides of the dry film is rolled up by the film rolling roller 303, and the upper copper foil roll is placed on the upper copper foil roller 401, and one end of the upper copper foil roll passes through the upper copper foil receiving platform 402 and the pressing structure 5 in sequence. After the upper copper foil, the dry film and the lower copper foil are pressed by the pressing structure 5, the pressed copper foil passes through the finished product receiving platform 601 and is rolled up by the winding roller 602.

[0027] See also Figure 1-Figure 6 During the process of laminating the upper copper foil, the dry film and the lower copper foil by the laminating structure 5, the power device drives the laminating roller 504 to rotate, and the triangular extrusion block 505 on the rotating laminating roller 504 first contacts the upper copper foil and the lower copper foil, and the extrusion block 505 on the upper laminating roller 504 pushes the upper copper foil to be extruded toward the dry film, and the extrusion block 505 on the lower laminating roller 504 pushes the lower copper foil to be extruded toward the dry film. Since the extrusion block 505 is triangular, the middle position of the upper copper foil and the lower copper foil is first extruded toward the dry film, thereby completing the lamination of the middle position of the upper copper foil, the dry film and the lower copper foil. In the subsequent rolling process of the laminating roller 504, the positions on both sides of the upper copper foil, the dry film and the lower copper foil are pressed again. By pressing the middle first and then pressing the two sides, the gas in the middle position of the upper copper foil, the dry film and the lower copper foil can be squeezed out, so as to prevent the gas in the middle position of the copper foil and the dry film from being difficult to discharge, resulting in the phenomenon of bubbles after the copper foil and the dry film are pressed.

[0028] Embodiment 2 Embodiment 2 is a further improvement on embodiment 1.

[0029] The difference from the first embodiment is that, please refer to Figure 7 and Figure 8The laminating roller 504 is provided with a plurality of cooling holes 510 arranged in a circular array and penetrating the laminating roller 504. Each cooling hole 510 penetrates the support groove at the bottom end of the same extrusion groove. Both ends of the cooling hole 510 are connected with a one-way valve 511 and a pressure relief valve 512 respectively. Rotary joints 513 are fixedly sleeved at both ends of the laminating roller 504. The rotary joints 513 include an inner ring and an outer ring. The inner rings of the two rotary joints 513 are connected with the one-way valve 511 and the pressure relief valve 512 respectively. A connecting pipe 514 is fixedly connected to the connecting port of the outer ring of the rotary joint 513. The supporting groove, the cooling hole 510 and the connecting pipe 514 are filled with coolant. Please refer to Figure 1 A cooling water tank 9 is fixedly mounted on the supporting shell 1 at the bottom of the pressing structure 5 , and the cooling water tank 9 contains coolant. The bottom end of the connecting pipe 514 on the outer ring of the rotary joint 513 is inserted into the transmission fluid in the cooling water tank 9 .

[0030] The flow direction of the one-way valve 511 is from the rotary joint 513 to the cooling hole 510 ; the flow direction of the pressure relief valve 512 is from the cooling hole 510 to another rotary joint 513 .

[0031] The working principle of the second embodiment of the present invention is as follows: See also Figure 1-Figure 8 , when the power device drives the pressing roller 504 to rotate, so that the pressing roller 504 presses the upper copper foil, the dry film and the lower copper foil, due to the pressing of the upper copper foil, the dry film and the lower copper foil by the extrusion block 505, in the process of the extrusion block 505 pressing the upper copper foil, the dry film and the lower copper foil, the reaction force of the upper copper foil, the dry film and the lower copper foil on the extrusion block 505 pushes the extrusion block 505, so that the extrusion block 505 rotates around the hinge shaft 506, so that the extrusion block 505 enters the extrusion groove. In this process, the extrusion block 505 will squeeze the support rod 508 and the support spring 507 at the same time, so that the support rod 508 moves into the support groove, so that the support rod 508 squeezes the coolant in the support groove, so that the coolant is discharged to the rotary joint 513 connected with the pressure relief valve 512 through the pressure relief valve 512, and then enters the cooling water tank 9 through the connecting pipe 514; After the power device drives the lamination roller 504 to rotate a certain angle, the extrusion block 505 is no longer squeezed. Under the action of the elastic force of the support spring 507, the support spring 507 pushes the support rod 508 to move to the outside of the support groove, thereby supporting the extrusion block 505. At the same time, since the support rod 508 slides to the outside of the support groove, a negative pressure is generated in the support groove, so that the support groove absorbs the coolant in the cooling water tank 9 through the one-way valve 511, the rotating joint 513 connected to the one-way valve 511, and the connecting pipe 514; in this process, the coolant in the support groove and the cooling hole 510 is circulated, thereby completing the cooling of the lamination roller 504, preventing the lamination roller 504 from increasing in temperature and expanding after working for a long time, resulting in a decrease in the distance between the two lamination rollers 504, thereby causing the copper foil to be squeezed and deformed, affecting the lamination effect of the copper foil.

[0032] Embodiment 3 Embodiment 3 is a further improvement on embodiment 2.

[0033] The difference from the second embodiment is that please refer to Figure 6-Figure 8 A supporting rubber block 516 is fixedly installed at the bottom of the supporting groove, a resistance strain gauge 515 is fixedly installed between the supporting rubber block 516 and the supporting spring 507, an electromagnetic block 519 is fixedly installed at the top of the resistance strain gauge 515 and in the supporting spring 507, a moving groove is opened on the side of the supporting rod 508 facing the electromagnetic block 519, a permanent magnet block 518 is slidably installed in the moving groove, and a slip ring 517 is fixedly sleeved on one end of the pressing roller 504, please refer to Figure 3 A current amplifier 520 is fixedly installed on the inner wall of a fixed frame 501 and close to the laminating roller 504. The resistance strain gauge 515, the slip ring 517, the electromagnetic block 519, the current amplifier 520, the control system 7 and the alarm device 8 are electrically connected; the extrusion block 505 is configured as a split type, and the extrusion block 505 is composed of two extrusion blocks, and the extrusion blocks are symmetrically arranged with the middle of the laminating roller 504 as the mirror plane.

[0034] The position of the top end of the resistance strain gauge 515 is lower than the position of the cooling hole 510 to prevent the resistance strain gauge 515 from blocking the cooling hole 510 .

[0035] A permanent magnet strip is fixedly mounted on the edge of the resistance strain gauge 515, and when the permanent magnet is energized, a magnetic force is generated to repel the permanent magnet block 518. When the permanent magnet block 518 is not subjected to external force, the permanent magnet block 518 slides into the moving groove of the support rod 508 to prevent the permanent magnet block 518 from falling off from the moving groove.

[0036] The working principle of the third embodiment of the present invention is as follows: See also Figure 1-Figure 8 , when the extrusion block 505 squeezes the support rod 508 and the support spring 507 to move the support rod 508 into the support groove, the supporting force of the support spring 507 is transmitted to the resistance strain gauge 515, so that the resistance strain gauge 515 is deformed. After the amplification of the current amplifier 520, the control system 7 detects the change in the current of the resistance strain gauge 515. When the extrusion blocks on both sides of the extrusion block 505 exert the same extrusion force on the resistance strain gauges 515 on both sides, the deformation amounts generated by the resistance strain gauges 515 on both sides are the same, and the current change amount detected by the control system 7 is within a fixed range; when the extrusion blocks on both sides of the extrusion block 505 exert different extrusion forces on the resistance strain gauges 515 on both sides, the deformation amounts generated by the resistance strain gauges 515 on both sides are different, and the current change amount detected by the control system 7 is not within the fixed range. The control system 7 controls the alarm device 8 to sound an alarm to remind the staff to adjust the spacing between the two lamination rollers 504; When the control system 7 detects that the resistance strain gauge 515 is deformed and generates a current change, the current passing through the current amplifier 520 is simultaneously passed through the electromagnetic block 519 (i.e., the electromagnetic block 519 is energized). The energized electromagnetic block 519 generates a magnetic force that attracts the permanent magnet block 518, causing the permanent magnet block 518 to slide toward the electromagnetic block 519, thereby further squeezing the coolant in the support groove, increasing the circulation volume of the coolant, and further cooling the laminating roller 504.
