[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0040] Example 1: A DF dry film lamination structure, see [link to example]. Figures 1 to 4 The system includes a base plate 1, with two slide rails A2 symmetrically fixed to the top side of the base plate 1. A sliding plate A4 is slidably connected to the two slide rails A2. Sliding blocks A at the front and rear ends of the bottom side of the sliding plate A4 are slidably connected to the two slide rails A2, respectively. A lead screw A3 is fixed to the top side of the base plate 1, with its nut A connected to the bottom side of the sliding plate A4. Two slide rails B5 are symmetrically fixed to the top side of the sliding plate A4, with a sliding plate B7 slidably connected to the two slide rails B5. Sliding blocks B at both ends of the bottom side of the sliding plate B7 are slidably connected to the two slide rails B5, respectively. The top side of the sliding plate A4 is fixed... The system includes a lead screw B6, with its nut B connected to the bottom of a movable plate B7. Lead screw A3 drives the movable plate A4 to move left and right, while lead screw B6 drives the movable plate B7 to move back and forth, thus adjusting the position of the plate after placement. It also includes a gantry frame 10, a hydraulic cylinder body 11, and a pressing structure 9. The gantry frame 10 is fixed to the base plate 1. The hydraulic cylinder body 11 is fixed to the transverse section of the gantry frame 10, and its use is selected by technical personnel based on actual conditions. The pressing structure 9 is located at the outer end of the piston rod of the hydraulic cylinder body 11.

[0041] The pressing structure 9 includes a pressure plate 901, a U-shaped frame 903, an end plate 905, and a heating tube body 904; the pressure plate 901 is connected to the outer end of the piston rod of the hydraulic cylinder body 11; wherein, a slot 9011 is provided on one side of the pressure plate 901; the U-shaped frame 903 is inserted into the slot 9011; the end plate 905 is fixed to the open end of the U-shaped frame 903; and several heating tube bodies 904 are connected to the end plate 905.

[0042] This utility model, by setting up a pressure plate 901, a U-shaped frame 903, an end plate 905, and a heating tube body 904, has the advantage that when the pressure plate 901 performs DF dry film pressing, the heat generated by the heating tube body 904 is directly transferred to the pressing point, which solves the problem that when the fixed heating tube is a certain distance from the pressing point, a large part of the heat transfer is dissipated into the air and wasted.

[0043] Specifically, four corner blocks 8 are fixed in a ring array on the top side of the transfer board B7, which define the circuit board placed on the transfer board B7.

[0044] Furthermore, a number of insertion holes 9031 are provided on the inner side of the end of the U-shaped frame 903, and the end of the heating tube body 904 is inserted into the insertion holes 9031; the heating tube body 904 is supported by the insertion of the end of the heating tube body 904 into the insertion holes 9031.

[0045] Furthermore, pull rings 907 are fixed at both ends of the outer side of the end plate 905, and pulling the pull rings 907 facilitates pulling the end plate 905 and the U-shaped frame 903.

[0046] It is worth noting that a copper sheet 902 is fixed on the pressing side of the pressure plate 901. The copper sheet 902 has good thermal conductivity and can better transfer heat.

[0047] It is worth noting that the two ends of the end plate 905 are positioned and engaged with the pressure plate 901 by positioning components 906 respectively;

[0048] The positioning component 906 includes a connecting plate 9061 and a locking block 9063. One end of the connecting plate 9061 is connected to the end of the end plate 905 via several torsion springs 9062. The elastic coefficient of the torsion springs 9062 is selected and used by the technical personnel in this field according to the actual situation. The locking block 9063 is fixed to the inner side of the other end of the connecting plate 9061. The locking block 9063 is arc-shaped, and the arched end of the locking block 9063 engages with the locking groove 9012 opened on the outer wall of the pressure plate 901. A stop block 9064 is fixed to the inner side of the connecting plate 9061, and the stop block 9064 engages with the end of the end plate 905. The stop block 9064 contacts the end of the end plate 905 to keep the connecting plate 9061 parallel to the end of the end plate 905, without affecting the opening of the arched end of the locking block 9063.

[0049] This utility model, by setting up a connecting plate 9061, a torsion spring 9062, a locking block 9063, and a locking groove 9012, has the advantage of quickly positioning the end plate 905 after it contacts the pressure plate 901, and keeping the end plate 905 in a stable position.

[0050] Working principle: Using the device of this utility model, the heating tube body 904 is sequentially inserted into the end plate 905, and the end of the heating tube body 904 is inserted into the insertion hole 9031. The U-shaped frame 903 is inserted into the slot 9011. When the end plate 905 is about to contact the pressure plate 901, the arched end of the locking block 9063 contacts the locking block 9063 and is squeezed. The connecting plate 9061 rotates outward under the action of the torsion spring 9062 until the end plate 905 contacts the pressure plate 901. Under the action of the torsion spring 9062, the connecting plate 9061 rotates back, and the arched end of the locking block 9063 is locked in the slot 9012, positioning the end plate 905. The circuit board is placed on the moving plate B7. The lead screw A3 drives the moving plate A4 to move left and right, and the lead screw B6 drives the moving plate B7 to move back and forth, thereby moving and adjusting the position of the placed circuit board. The hydraulic cylinder body 11 pushes the pressure plate 901 down, and the copper sheet 902 presses the circuit board. The heat generated by the heating tube body 904 is directly transferred to the pressing point.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations.
