According to the number of layers of the circuit board, it can be divided into single-layer board, double-layer board, four-layer board, six-layer board and other multi-layer circuit boards.

[0003] During the production process of PCB, it is necessary to arrange the substrate, prepreg copper foil, etc. At present, in order to ensure the accuracy of the arrangement, the arrangement of the substrates is mostly done by pre-opening positioning holes on each substrate, and then stacking the substrates by manually aligning the positioning holes. This method requires opening holes in advance, which increases the process. In addition, considering the influence of the interference layer, in order not to affect the signal transmission, a large area of ​​copper-free area appears in the design of the substrate.

[0030] The ejection mechanism includes four through holes 8, four sleeves 9, four limit push rods 10, four lower circular plates 11, four rubber round blocks 12, four upper circular plates 13, a lifting plate 14, a driving screw 15 and an electric motor 17. The four through holes 8 are all opened at the bottom of the workbench 1, and the four through holes 8 are distributed in a rectangular shape. The four sleeves 9 are respectively fixedly installed in the four through holes 8, and the four limit push rods 10 are respectively slidably installed on the four sleeves 9. The four lower circular plates 11 are respectively arranged in the four through holes 8, and the four lower circular plates 11 are respectively fixedly installed on the top ends of the four limit push rods 10. The rubber round blocks 12 are respectively fixedly mounted on the tops of the four lower circular plates 11, and the four upper circular plates 13 are respectively fixedly mounted on the tops of the four rubber round blocks 12. The lifting plate 14 is arranged between the workbench 1 and the connecting plate 16. The bottom ends of the four limit push rods 10 extend to the bottom of the workbench 1 and are fixedly connected to the lifting plate 14. The driving screw rod 15 is threadedly mounted on the lifting plate 14, and the top end of the driving screw rod 15 is rotatably connected to the workbench 1. The electric motor 17 is fixedly mounted on the top of the connecting plate 16, and the lower end of the driving screw rod 15 is fixedly connected to the output shaft of the electric motor 17.

[0031] Four rectangularly distributed positioning columns are fixedly installed on the top of the workbench 1, and four rectangularly distributed positioning grooves are opened on the bottom of the lower steel plate 3, and the positioning grooves are adapted to the positioning columns, and the top ends of the four positioning columns extend into the corresponding positioning grooves.

[0032] Four rectangularly distributed limiting columns are fixedly mounted on the top of the lower steel plate 3 , and four rectangularly distributed limiting holes are opened on the top of the upper steel plate 18 , and the limiting holes are matched with the limiting columns.

[0033] A linear bearing is fixedly installed in the sleeve 9, and the limiting push rod 10 passes through the linear bearing and is slidably connected to the inner wall of the linear bearing.

[0034] A fixing hole is provided on the top of the lifting plate 14, a nut is fixedly installed in the fixing hole, the driving screw 15 passes through the nut and is screwed with the inner wall of the nut, and four rectangular limiting blocks are fixedly installed at the bottom of the workbench 1.

[0036] In this embodiment, when in use, first align the four positioning grooves on the lower steel plate 3 with the four positioning columns on the workbench 1 and lower it, so that the position of the lower steel plate 3 can be accurately found, and then start the output shafts of the two first hydraulic cylinders 4 and the two second hydraulic cylinders 6 to a preset length, the two first limiting plates 5 and the two second limiting plates 7 will be displaced to the top of the lower steel plate 3 and form a limiting area, and then the PCB substrate can be placed in the limiting area in sequence according to the stacking order.

Since the driving screw 15 and the lifting plate 14 are threadedly connected, and the lifting plate 14 is limited by four limit push rods 10, the lifting plate 14 will move upward during the rotation of the driving screw 15. Driven by the lifting plate 14, the four limit push rods 10 will move upward, thereby driving the four upper circular plates 13 to move upward. Finally, the four upper circular plates 13 cooperate to push the lower steel plate 3 to separate from the workbench 1, and separate the four positioning columns from the corresponding positioning grooves.

After the PCB substrates are placed in the limiting area in sequence according to the stacking order, the alignment can be automatically completed. There is no need to pre-open positioning holes on the substrates, which can reduce the production process. After the stacking is completed and the upper steel plate 18 is covered, the output shaft of the electric motor 17 is started to rotate forward, so that the four limit push rods 10 can move upward, thereby driving the four upper circular plates 13 to move upward. Finally, the four upper circular plates 13 can cooperate to push the lower steel plate 3 to separate from the workbench 1 and lose the limitation, so that it is more convenient for the staff to pick it up. In the process of driving the lower steel plate 3 to rise, the four rubber round blocks 12 can play a buffering role to prevent the lower steel plate 3 from sliding due to mechanical vibration. It is easy and reliable to use. Example

[0038] This embodiment proposes a method for arranging panels in an open area, comprising the following steps:

[0039] S1: Select two aluminum plates and two PE films, and cut the aluminum plates and PE films to make them consistent in size with the semi-cured plates, inner layer plates and other substrates.

[0040] S2: First, place the lower steel plate at the designated position on the workbench of the open area plate arrangement device, then start the hydraulic limiting system on the open area plate arrangement device to make the four limiting plates form a stacking limiting area above the lower steel plate, then place an aluminum plate on the surface of the lower steel plate in the stacking limiting area, then put in a PE film, then stack the copper foil, semi-cured board, inner layer board and other substrates, and make the open area of ​​the substrate overlap, after the substrate is stacked, cover it with another PE film, and then stack another aluminum plate on the top layer, finally cover the upper steel plate, and align the upper steel plate with the lower steel plate to limit it.

[0041] S3: Put the stacked substrate into a fast pressing machine for pressing. After the pressing is completed, separate the upper steel plate and the lower steel plate from the pressed substrate.

[0042] In this embodiment, PE film and aluminum plate are used for double coating at the bottom and top of the substrate. Since the PE film is a coating material with relatively slight fluidity, the aluminum plate plays a role of isolation and reinforcement, which can promote uniform force, thereby avoiding the occurrence of copper wrinkles and reducing the probability of insufficient glue filling.
