Technical Field

[0001] The utility model relates to the technical field of PCB manufacturing, in particular to a circuit board reinforcement pressing mold. Background Art

[0002] Rigid-flex boards are a special type of multi-layer printed circuit board that combines the features of rigid boards and flexible boards. Rigid-flex boards are usually made up of alternating rigid layers and flexible layers. Rigid-flex boards are widely used in the field of electronic products due to their modular design and three-dimensional installation advantages. Rigid-flex boards with flying tail structures have become a rapidly developing field in recent years because they improve the reliability and flexibility of circuit connections. With the development of technology and the continuous improvement of market demand, a single flying tail structure can no longer meet the increasingly complex circuit design needs, and rigid-flex boards with multiple flying tail structures have come into being.

[0003] The traditional multi-tail rigid-flex board reinforcement and pressing process has the disadvantages of low efficiency and difficult quality assurance. The existing technology generally adopts the method of multiple pressings for each tail reinforcement, which requires manual operation, has a complicated process and low efficiency.

[0004] In order to solve the deficiencies in the prior art, there is an urgent need for a circuit board reinforcement and pressing mold that can improve the efficiency of reinforcing and pressing a multi-flying tail rigid-flex board. Utility Model Content

[0005] In order to overcome the problems existing in the related art, the purpose of the utility model is to provide a circuit board reinforcement pressing mold to solve the problem of low efficiency of reinforcement pressing of multi-tail rigid-flex boards existing in the prior art.

[0006] A circuit board reinforcement pressing mold, comprising:

[0007] A plurality of lamination support plates are arranged in parallel, and elastic brackets are arranged between the plurality of lamination support plates. The elastic brackets separate the lamination support plates to form a lamination space, and the lamination space is used to place the soft board with the reinforcement plate attached thereto.

[0008] By setting a pressing support plate and using an elastic bracket to separate and form a pressing space, the soft board with a reinforcement plate can be pressed synchronously, thereby improving the efficiency of the reinforcement pressing of the multi-flying tail rigid-flex board.

[0009] In some embodiments, gaskets are provided on adjacent surfaces of several of the pressed support plates.

[0010] Providing gaskets on adjacent surfaces of the pressing support plate can effectively prevent the reinforcement plate from shifting during the pressing process, thereby improving the precision and quality of the pressing.

[0011] In some embodiments, a positioning column is further included, one end of which is fixedly connected to the pressing support plate on the end side, and the other end of which vertically passes through the remaining pressing support plates.

[0012] One end of the positioning column is fixedly connected to the pressing support plate on the end side, and the other pressing support plates are sleeved on the positioning column, which simplifies the structure of the mold, facilitates the assembly and disassembly of the mold, and improves the practicability of the mold.

[0013] In some embodiments, a positioning column is further included, wherein the positioning column is perpendicular to the pressed support plate, and both ends of the positioning column are fixedly connected to the pressed support plates at both ends respectively, and the positioning column can be extended and retracted along its axial direction.

[0014] The positioning column is designed to be a retractable structure, so that the entire pressing mold can be placed in the pressing machine for pressing during pressing, which can reduce the alignment time of the mold and the pressing machine and effectively improve the pressing efficiency.

[0015] In some embodiments, the plurality of pressed support plates include two first support plates and a plurality of second support plates, the two first support plates are located on both sides, the plurality of second support plates are located in the middle, and the thickness of the first support plates is greater than the thickness of the second support plates.

[0016] By providing the first support plate and the second support plate of different thicknesses, the pressure distribution during the pressing process can be effectively controlled to ensure that the reinforcement plates at different positions can be pressed evenly, thereby improving the pressing quality.

[0017] In some embodiments, the elastic bracket is a spring, and the spring is sleeved on the positioning column.

[0018] Using springs as elastic brackets can effectively separate the pressing support plates, making it convenient to place the soft board. The springs provide support for the pressing support plates before and after pressing, and the pressing support plates are separated. When pressing, the springs are compressed and the pressing support plates are moved closer to each other.

[0019] In some embodiments, the compression support plate is further provided with a card block, and the positioning column is further provided with a card slot, and the card block cooperates with the card slot. When the card block is inserted into the card slot, the compression support plate is fixed on the positioning column.

[0020] Through the cooperation of the clamping block and the clamping slot, the pressed support plate can be firmly fixed on the positioning column to prevent the elastic bracket from being stressed for a long time.

[0021] In some embodiments, the gasket is made of silicone material, and the gasket is fixedly connected to the pressed support plate.

[0022] Using silicone material as a gasket can effectively disperse the pressure during the pressing process, ensure the average force on the reinforcement plate during the pressing process, and improve the pressing effect.

[0023] In some embodiments, the laminated support plate is made of steel.

[0024] Using steel material as the pressing support plate can improve the strength and durability of the mold and extend the service life of the mold.

[0025] In some embodiments, the elastic bracket is a magnet group, and the magnet group is mounted on the positioning column. Each of the magnet groups includes two magnets, and the two magnets are respectively fixed on the pressing support plate.

[0026] Using magnets as elastic supports can achieve contactless pressing, avoid wear and noise caused by mechanical contact, and improve the precision and service life of the mold.

[0027] The beneficial effects of the utility model are:

[0048] Specifically, the pressing support plate 200 is made of steel material, and the gasket 600 is made of silicone material.

[0049] More specifically, two positioning posts 100 are also included, and the two ends of the positioning posts 100 are respectively fixedly connected to the pressing support plates 200 located at the two ends, and the positioning posts 100 can be extended and retracted along the axis direction. The pressing support plates 200 are connected by magnets, and the magnets are annular, and the annular magnets are sleeved on the positioning posts 100.

[0050] That is to say, in this embodiment, there are 8 groups of magnets, with a total of 16 magnets. The magnets can be permanent magnets or electromagnets. In this embodiment, the magnets are permanent magnets. Two magnets in the same magnet group repel each other.
