Description

Technical Field

[0001] This utility model relates to the field of circuit board processing and pressing technology, and in particular to a pressing mechanism for circuit board production and processing. Background Technology

[0002] Circuit board lamination is a key process in multilayer PCB manufacturing, bonding the core board, prepreg (PP), and copper foil together under high temperature and pressure. This process must be carried out in a vacuum environment, with temperatures typically controlled at 180-200℃ and pressures reaching 15-30 kg / cm². 2 This process ensures resin flow fills gaps and eliminates air bubbles. The lamination process consists of three stages: preheating, constant pressure curing, and cooling, ultimately forming a multilayer structure with stable dielectric properties and mechanical strength. Modern lamination equipment (such as vacuum laminators) can precisely control parameters to meet the stringent requirements of high-frequency, high-speed boards for consistent interlayer thickness (±5μm) and dielectric constant. This technology directly affects PCB reliability and is a core component for ensuring signal integrity and heat dissipation performance.

[0003] In the production process of existing circuit boards, they need to be pressed together into a whole. However, traditional pressing equipment cannot be adjusted according to the needs when pressing different circuit boards. It is necessary to clamp and limit the circuit boards to prevent displacement. This results in slow clamping speed for smaller circuit boards. At the same time, the pressure applied when pressing the circuit boards is not easy to adjust and control, which is inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a pressing mechanism for circuit board production and processing, which solves the problem that traditional pressing equipment cannot be adjusted according to needs when pressing different circuit boards, and requires clamping and limiting the circuit board to prevent displacement, resulting in slow clamping speed for smaller circuit boards.

[0005] To achieve the above objectives, a pressing mechanism for circuit board manufacturing is provided, comprising: a pressing table, wherein a first sliding groove is provided on both sides of the inner side of the pressing table, a movable frame is slidably fitted inside the first sliding groove, a clamping plate is fixedly connected to the top of the movable frame, an opening groove is provided in the middle of the bottom end of the pressing table, a bidirectional screw is rotatably connected inside the opening groove, both sides of the middle part of the bidirectional screw are threadedly fitted with the movable frame, a rear side plate is fixedly connected to the middle of the rear side of the pressing table, a top plate is fixedly connected to the top of the rear side plate, an electric telescopic rod is fixedly connected to the middle of the top of the top of the top plate, and a lower pressure plate is fixedly connected to the extension end of the electric telescopic rod.

The extension end of the electric telescopic rod 4 is fixedly connected to the lower pressure plate 16.

[0026] Rotating rods 18 extend through both sides of the middle of the top plate 13. A threaded rod 14 is fixedly connected to the top of each rotating rod 18. A threaded block 15 is threadedly connected to the upper middle of the threaded rod 14. When the downward force of the lower pressure plate 16 needs to be adjusted, the threaded block 15 can be rotated. After rotation, it engages with the threaded rod 14, thus controlling the downward extension length and improving the downward pressure control. The threaded block 15 and the top plate 13 are in contact. Second sliding grooves 9 are provided at the four corners of the middle of the pressing table 1. Support springs 10 are fixedly connected inside the second sliding grooves 9. The support springs 10 are elastically compressed, allowing the L-shaped clamping plate 11 to clamp the circuit board 5.

The L-shaped clamping plate 11 is expanded and the support spring 10 is elastically compressed. At this time, the L-shaped clamping plate 11 can clamp the circuit board 5. After clamping, the electric telescopic rod 4 descends. After descending, the lower pressure plate 16 moves downward to perform the pressing operation on the circuit board 5. When the circuit board 5 is large, it can be placed above the pressing table 1. The drive motor 2 drives the bidirectional screw 7 to rotate. After rotation, it moves with the moving frame 8.
