[0025] The extrusion structure 2 includes a backlog rack 21 fixedly mounted on the outer walls of both sides of the prepreg box 11, and a hydraulic telescopic rod 22 is fixedly mounted on the outer wall of the top of the backlog rack 21.

[0026] The transport structure 3 includes a sliding plate 31 slidably connected to the upper surface of the conveyor belt 146 , and connecting blocks 35 are fixedly installed on the outer walls of both sides.

[0027] It should be noted that, in this embodiment, by starting the drive motor 13, one end of the drive motor 13 is used to drive the number one gear 131 to rotate, and the outer wall of the number one gear 131 is engaged with the outer wall of the inner side of the toothed belt 145, so that the toothed belt 145 rotates, and the number two gear 143 on the other inner outer wall of the toothed belt 145 rotates, thereby rotating through the rotating column 148 inside the number two gear 143, and when the rotating column 148 rotates, it drives the transmission roller 144 to rotate, so that the outer wall of the transmission roller 144 drives the transmission belt 146 to transmit, and the upper surface of the transmission belt 146 is used to transmit the transport structure 3.

[0028] like Figure 1-Figure 3As shown, the inner side of the middle part of the connecting block 35 is slidably connected to the driving rod 34, and the outer wall of the driving rod 34 and the upper surface of the connecting block 35 are movably sleeved with a movable spring 36, one end of the top of the driving rod 34 is fixedly installed with a pressure plate 37, one end of the bottom of the driving rod 34 and the lower surface of the connecting block 35 is fixedly connected to the driving block 32, and the bottom of the driving block 32 is fixedly installed with a filter basket 33, a limiting groove 38 is provided in the middle part of the bottom of the sliding plate 31, and a limiting plug 39 is fixedly installed in the middle part of the top of the sliding plate 31, and one end of the bottom of the hydraulic telescopic rod 22 is fixedly installed with a backlog plate 23, and the outer wall in the middle of the backlog plate 23 is provided with a slot 231.

[0029] It should be noted that, in this embodiment, the transport structure 3 is located on the inner side of the top of the prepreg box 11, and then the hydraulic telescopic rod 22 is started. The backlog plate 23 is pushed by the hydraulic telescopic rod 22, so that the bottom of the backlog plate 23 is backlogged on the pressure plate 37, and the bottom of the pressure plate 37 drives the driving rod 34 to slide on the inner side of the middle of the connecting block 35, so that the driving rod 34 drives the driving block 32 to descend, and when the driving block 32 descends, it drives the filter placement basket 33 to enter the prepreg box 11 for prepreg treatment. When the backlog plate 23 rises, the filter placement basket 33 can be reset by the movable spring 36, and when the backlog plate 23 is backlogging on the pressure plate 37, the limiting plug 39 is inserted into the inner side of the slot 231 to limit it.

[0030] like Figure 1 、 Figure 3 、 Figure 4 As shown, an air pipe 17 is fixedly installed at one end of the air pump 16 and at the bottom of the inner wall of the prepreg box 11.

When the backlog plate 23 rises, the filter basket 33 can be reset by the movable spring 36, and when the backlog plate 23 backlogs the pressure plate 37, the limiting plug 39 is inserted into the inner side of the slot 231 to limit it.

[0034] When the filter basket 33 carrying the nickel-gold-plated circuit board enters between the limit frames 173, the air pump 16 is started, and the gas is transmitted to the inside of the air pipe 17 through the air pump 16. The gas is discharged through the exhaust holes 171 on both sides of the outer wall of the air pipe 17, so that the etching liquid will not settle, allowing the nickel-gold-plated circuit board inside the filter basket 33 to be pre-impregnated, thereby improving the effect of the pre-impregnation treatment.
