Single-layer boards refer to boards with only one circuit layer on the surface of the substrate, double-layer boards refer to boards with circuit layers on both sides of the substrate, and multi-layer boards are made by adding copper foil layers to the outside of the core board in sequence using prepregs on the basis of double-layer boards. It should be noted that the semi-finished multi-layer boards are only formed by sequentially pasting prepregs and copper foil layers on the core board. The semi-finished multi-layer boards need to be placed in a laminating device for lamination operations to make the semi-finished multi-layer boards into a multi-layer circuit board with an integrated structure.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The pressing table is moved by an electric slide rail, and the interaction between the telescopic plate and the guide wheel is used to realize rapid loading and unloading. Before pressing, the telescopic plate rises along the guide plate to lift the pressing table and the material under the pressing plate; after pressing, the telescopic plate descends along the other side of the guide plate, and the pressing table continues to move. The telescopic plate shrinks under the guidance of the limit plate, so that the bottom of the pressing table contacts the sliding part, realizing rapid and stable loading and unloading of circuit boards and improving production capacity.

[0016] 2. When the pressing table is lifted by the telescopic plate and moved to the bottom of the pressing plate, the magnetic suction piece of the second cylinder is reinserted into the inner wall of the support table and firmly attracted to it. At this time, the magnetic suction pieces of the first cylinder and the second cylinder work together to accurately position the support table to ensure that the support table is stable and immovable. At the same time, the support arm provides additional support to the support table from below, further enhancing the stability of the support table. In the process of the hydraulic rod pushing the pressing plate downward to press the material, the bottom of the pressing table fits tightly against the top of the support table. Since the support table provides a solid support surface, it can effectively disperse the pressure applied by the pressing plate and prevent the pressing table from bending and deforming in the middle due to uneven force. The support table not only ensures the smooth progress of the pressing process, but also protects the structural integrity of the pressing table and extends its service life.

[0017] 3. The electric slide rail drives the sliding part to slide in the opposite direction. At this time, the telescopic plate has been stored in the pressing table, and the pressing table slides horizontally and linearly along the inner walls of the two inner guide plates. This design ensures the stability and accuracy of the pressing table during the resetting process, avoids unnecessary deviation or shaking, and thus achieves fast and smooth resetting. During the movement, the pressing table squeezes the rotating arms on the support table in turn through the rollers to ensure that there is always one side of the support arm to support the bottom of the support table, which improves the stability of the support table and enables the pressing table to pass through the bottom of the support table smoothly and quickly, and slide horizontally in a straight line, thereby quickly resetting.

[0033] Working principle: The multi-layer materials of the circuit board are stacked in sequence between the two baffles 206 on the top of the pallet 202, and the baffles 206 are used to limit the two sides of the materials; The electric slide rail 102 drives the pressing table 201 to move through the sliding part 103, and the pressing table 201 drives the telescopic plates 209 on both sides to move, and the second cylinder 3031 contracts, and the magnetic suction piece 3032 at its end is pulled out from the inner wall of the support table 301, and the second arc surface 211 on the telescopic plate 209 contacts the guide wheel 115 in the guide plate 108, and under the elastic support of the first spring 112, it rolls upward along the guide wheel 115 inclined on one side, and the telescopic plate 209 lifts the pressing table 201 upward, and the pressing table 201 and the support plate 202 slide upward along the connecting rod 203, and the second spring 205 is stretched, and the material is moved to the bottom of the pressing plate 106 through the support plate 202, and the second cylinder 3031 pushes the magnetic suction piece 303 2 moves downward, inserts into the inner wall of the support platform 301 and attracts it, the magnetic suction piece 3032 at the output end of the first cylinder 303 and the second cylinder 3031 positions the support platform 301, and the support arm 311 supports the bottom of the support platform 301. At this time, the electric slide rail 102 stops, and the hydraulic rod 105 pushes the pressing plate 106 downward to press the material. Under the action of pressure, the guide wheel 115 under the telescopic plate 209 pushes the first slide bar 110 to slide downward along the partition 109 in the opposite direction, and the first spring 112 is compressed. At this time, the bottom of the pressing platform 201 is located at the top of the support platform 301, and the pressing platform 201 is effectively supported by the support platform 301, so as to improve the stability of the pressing platform 201 and avoid bending and deformation of the middle part of the pressing platform 201; After pressing, the first cylinder 303 contracts, and the magnetic attraction piece 3032 at its end is pulled out from the inner wall of the support platform 301. Under the elastic force of the first spring 112, the guide wheel 115 rebounds, and the electric slide rail 102 is started, driving the pressing platform 201 to move. The pressing platform 201 moves downward along the inclined guide wheel 115 on the other side. After the pressing platform 201 moves away from the top of the support platform 301, the first cylinder 303 pushes the magnetic attraction piece 3032 to be inserted into the support platform 301. When the first curved surface 210 on the telescopic plate 209 slides in contact with the limit plate 107, the telescopic plate 209 moves to the telescopic groove under the guidance of the limit plate 107. 208, the telescopic plate 209 pushes the fixed rod 212 to slide into the installation cavity 207, so that the third spring 214 is compressed. When the telescopic plate 209 is squeezed by the narrower side of the two limit plates 107, the telescopic plate 209 is completely retracted into the telescopic groove 208, and the pressing table 201 continues to move. The telescopic plate 209 is out of contact with the guide wheel 115. Under the elastic force of the second spring 205, the bottom of the pressing table 201 contacts the sliding part 103. At this time, the pressed circuit board moves to the other side of the mounting seat 101, realizing fast loading and unloading. The circuit board can be taken out by installing a manipulator; After unloading, the electric slide rail 102 drives the sliding part 103 to slide in the opposite direction. At this time, the telescopic plate 209 is stored in the pressing table 201, and the two sides of the pressing table 201 slide along the inner walls of the two inner guide plates 108, so that the pressing table 201 slides horizontally and linearly to achieve rapid reset; When the pressing table 201 moves, the roller 216 squeezes the rotating arm 310 on one side of the support table 304, and the rotating arm 310 pushes the slide 308 to slide along the second slide bar 306 and compresses the fourth spring 307. The rotating arm 310 drives the support arm 311 to rotate, and the support arm 311 rotates through the first fixed shaft 317. The first fixed shaft 317 drives the transmission wheel 320 to rotate through the driving wheel 318. When the transmission wheel 320 rotates, under the damping action of the damping ring 3171, the convex part of the transmission wheel 320 pushes the driving wheel 318 on the other side to move, and the driving wheel 318 drives the slider 314 along the first fixed shaft 317. The third slide bar 315 slides, the fifth spring 316 is compressed, and the end of the support arm 311 on the other side slides along the horizontal side of the guide surface 302, and can always support one side of the support platform 301, thereby improving the stability of the support platform 301. The pressing platform 201 moves between the two support arms 311, and under the elastic force of the fourth spring 307, the support arm 311 rebounds to support the bottom of the support platform 301 again, and the pressing platform 201 continues to move and squeezes the support arm 311 on the other side. At this time, the support arm 311 is separated from the support for the bottom of the support platform 301, so that the pressing platform 201 can quickly pass through the bottom of the support platform 301 to achieve reset.
