[0002] Circuit board fixing fixtures play a crucial role in electronics manufacturing. They primarily ensure the stable position of the circuit board during processing through mechanical structure design, preventing displacement during soldering or testing and thus guaranteeing process accuracy. However, current technologies mostly rely on screws for fixing circuit boards. For thin boards, this can easily lead to deformation or cracking due to stress concentration, exhibiting poor adaptability. Repeated disassembly and reassembly can damage threaded holes, reducing the reliability of the fixing. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a dual-station circuit board fixing fixture, which has the advantage of high applicability and solves the problem that fixing with screws can easily cause stress concentration and deformation of thin plates, resulting in poor applicability.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A dual-station circuit board fixing fixture includes a worktable serving as the main body of the device. A partition strip is fixedly connected to the top of the worktable, dividing it into different working areas. Two symmetrical adjustment slots are formed on the worktable about the partition strip. Adjustment plates for accommodating circuit boards of different sizes are installed in each adjustment slot. A fixing plate is mounted on the adjustment plate via a damping shaft. A connecting plate is fixedly connected to one side of the fixing plate. Multiple hemispherical blocks are mounted on one side of the connecting plate, each hemispherical block having a grid pattern to increase clamping friction. A turntable is fixedly connected to one end of the damping shaft, and an indicator needle is fixedly connected to the turntable. An angle disc is provided on one side of each fixing plate to facilitate precise adjustment of the circuit board angle.

[0005] Preferably, a bidirectional screw is rotatably connected inside the adjustment groove, a guide rod is fixedly connected inside the adjustment groove, and two servo motors for driving the bidirectional screw are respectively installed on one side of the worktable.

[0006] Preferably, the adjusting plate is provided with a sliding hole that is slidably connected to the guide rod and a threaded hole that is threadedly connected to the bidirectional screw.

[0007] Preferably, the two adjusting plates located in the same adjusting groove are symmetrically arranged and are located on different thread sections of the same bidirectional screw.

[0008] Preferably, the multiple hemispherical blocks located on the same connecting plate are arranged in a linear array, and the hemispherical blocks are made of silicone.

[0009] Preferably, when adjusting the angle of the circuit board, the two opposing adjustment plates need to rotate synchronously, and the pointing direction of the indicator needle should remain consistent.

[0010] By employing the above technical solution, this utility model provides a dual-station circuit board fixing fixture, which has at least the following beneficial effects: 1. This utility model enables the device to clamp and fix circuit boards of different specifications by setting a bidirectional screw and an adjusting plate. Multiple hemispherical blocks form multi-point contact with the circuit board, dispersing the clamping stress. The curved surface can adapt to the edges of different circuit boards, making the clamping contact of the circuit board more uniform and improving the applicability of the device. At the same time, the mesh pattern further increases the friction between the hemispherical blocks and the circuit board, improving the fixing effect of the device.

[0011] 2. This utility model enables the worktable to be divided into two workstations by setting two servo motors and a partition bar, thereby fixing different circuit boards and improving the processing efficiency of the device. The damping shaft makes it easy to adjust the processing angle of the circuit board after it is fixed. The indicator needle on the turntable corresponds to the angle dial, thereby improving the accuracy of the processing angle adjustment. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the prior art, circuit boards are mostly fixed by screws. For thin boards, stress concentration can easily lead to deformation or cracking, resulting in poor adaptability. Repeated disassembly can damage the threaded holes and reduce the reliability of the fixation. The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a dual-station circuit board fixing fixture.

[0016] Example 1: In order to combine Figures 1-4 As shown, a dual-station circuit board fixing fixture is proposed. The fixture is constructed by setting a workbench 1 as the main body of the device. Two adjustment slots 2 are provided on the workbench 1, which are symmetrical about the partition strip 3. Adjustment plates 6 are installed in each adjustment slot 2. By adjusting the adjustment plates 6, the spacing can be adapted to circuit boards of different specifications.

[0017] A fixed plate 10 is mounted on the adjusting plate 6 via a damping shaft. A connecting plate 11 is fixedly connected to one side of the fixed plate 10. Multiple hemispherical blocks 12 are mounted on one side of the connecting plate 11. Each hemispherical block 12 has a grid pattern 13 to increase clamping friction. A turntable 14 is fixedly connected to one end of the damping shaft. An indicator needle 15 is fixedly connected to the turntable 14. An angle dial 16 is provided on one side of the fixed plate 10 to facilitate precise adjustment of the circuit board angle. The multiple hemispherical blocks 12 located on the same connecting plate 11 are arranged in a linear array. The hemispherical blocks 12 are made of silicone. When adjusting the angle of the circuit board, the two opposite adjustment plates need to be adjusted. The plate 6 rotates synchronously, and the direction indicated by the indicator needle 15 remains consistent. Multiple hemispherical blocks 12 form multi-point contact with the circuit board, dispersing the clamping stress. The curved surface can adapt to different circuit board edges, making the clamping contact of the circuit board more uniform and improving the applicability of the device. At the same time, the friction between the hemispherical blocks 12 and the circuit board is further increased by the grid pattern 13, improving the fixing effect of the device. The damping shaft allows for easy adjustment of the processing angle of the circuit board after it is fixed. The indicator needle 15 on the turntable 14 corresponds to the angle plate 16, thereby improving the accuracy of the processing angle adjustment.

[0018] Example 2: Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem that in the prior art, when fixing circuit boards, screws are mostly used, which can easily cause deformation or cracking due to stress concentration in thin boards, resulting in poor adaptability. However, in order to improve the processing efficiency of circuit boards, a dual-station is now set up so that two circuit boards can be fixed and processed at the same time.

[0019] To improve the processing efficiency of circuit boards, combined with Figure 1 and Figure 2As shown, a partition strip 3 is fixedly connected to the top of the workbench 1, dividing the workbench 1 into different working areas. A bidirectional screw 4 is rotatably connected in the adjustment groove 2, and a guide rod 5 is fixedly connected in the adjustment groove 2. Two servo motors 7 for driving the bidirectional screw 4 are installed on one side of the workbench 1. The adjustment plate 6 is provided with a sliding hole 9 that is slidably connected to the guide rod 5 and a screw hole 8 that is threadedly connected to the bidirectional screw 4. The two adjustment plates 6 located in the same adjustment groove 2 are symmetrically arranged and are located on different thread sections of the same bidirectional screw 4. The workbench 1 is divided into two workstations by the partition strip 3. The two servo motors 7 drive the corresponding adjustment plates 6 to adapt to different circuit boards, which greatly improves the processing efficiency of the device.
