Description

Technical Field

[0001] The invention relates to the technical field of circuit board plugging, in particular to an adjustable plug-in type multi-layer circuit board plugging process. Background Art

[0002] Circuit board plugging is a key link in electronic manufacturing. In the neat and orderly production workshop, technicians are concentrating on the work of circuit board plugging. They hold precise electronic components and accurately insert them into the corresponding sockets on the circuit board. Each socket is carefully designed to ensure that the components can be firmly connected. The plugging process requires a high degree of precision and patience. The slightest deviation may affect the performance of the entire electronic device. With rich experience and professional skills, technicians carefully check each plug point to ensure reliable connection. Circuit board plugging is like the cornerstone of building the electronic world, giving life to various advanced electronic devices. It is not only a technical work, but also a commitment to quality and reliability, providing solid support for the development of modern science and technology.

[0003] During the plug-in process of multi-layer circuit boards, if the distance between the lines is too close, the capacitive coupling between different signal lines will increase, which may cause interference between the signals and affect the integrity and accuracy of the signals. For example, in high-speed digital circuits, problems such as signal distortion and increased bit error rate may occur. At the same time, too close spacing is prone to crosstalk, that is, the signal on one line will couple to the adjacent line. This will degrade the performance of the circuit, especially in high-frequency and high-speed circuits, where crosstalk may cause serious signal quality problems. Summary of the invention

By setting the clamping mechanism 3, one side of the multi-layer circuit board can be clamped and placed, and under the action of the adjusting mechanism 5 and the squeezing mechanism 9, the multi-layer circuit board can be stably set just above the base 1. By setting the track frame 31, the sliding rod 32 can be limited so that the sliding rod 32 can produce a vertical up and down movement effect in the inner cavity of the track frame 31. By setting the track ring 4, the adjusting mechanism 5 can be limited so that the adjusting mechanism 5 can produce an up and down movement effect. By setting the adjusting mechanism 5, after the multi-layer circuit board is placed, the distance between the two circuit boards can be adaptively adjusted, thereby preventing the distance between the two circuit boards from being too close to cause line entanglement, or the distance from each other to be too far to waste space. By setting the squeezing mechanism 9, the multi-layer circuit board placed by the clamping mechanism 3 can be squeezed, thereby tightly positioning the multi-layer circuit board.

[0017] The number of the sliding rods 32 is several, and the sliding rods 32 are evenly distributed. The end of the sliding rod 32 away from the bending rod 33 is fixedly connected to the first sliding bearing 34, and the inner ring of the first sliding bearing 34 is fixedly connected to a connecting block 35.

The output end of the motor 7 is installed with a rotating rod 8 through a coupling, and the top of the rotating rod 8 is fixedly connected to a threaded rod 55, and the threaded rod 55 is threadedly connected to the threaded ring 54. By providing the second sliding bearing 53, the threaded ring 54 and the connecting rod 52 can produce a relative rotation effect. By providing the motor 7, after the power is connected and the switch is turned on, the rotating rod 8 can drive the threaded rod 55 to rotate, thereby causing the threaded ring 54 to rotate.

[0019] The extrusion mechanism 9 includes a track bar 91, and the track bar 91 is fixedly connected to the inner wall of the base 1. The outer surface of the track bar 91 is slidably connected to a sliding ring 92. The sliding ring 92 is fixedly connected to a movable frame 93 on the side away from the track bar 91. The outer side of the movable frame 93 is fixedly connected to a second spring 94. The end of the second spring 94 is fixedly connected to the inner wall of the base 1. By setting the track bar 91, the sliding ring 92 can be limited so that the sliding ring 92 can slide stably on the outer surface of the track bar 91. By setting the movable frame 93 and the second spring 94, the movable frame 93 can be moved toward the fixed frame 2 under the pull of the second spring 94. The upper surface of the movable frame 93 A limiting rod 95 is fixedly connected to the surface, and a sliding ring 96 is slidably connected to the outer surface of the limiting rod 95. A fixing plate 97 is fixedly connected to the outer surface of the sliding ring 96. A second placing frame 98 is fixedly connected to the fixing plate 97 on the side of the fixing plate 97 close to the first placing frame 37. A track rod 99 is fixedly connected to the lower surface of the second placing frame 98. The track rod 99 is frictionally matched with the inner wall of the limiting ring 38. By setting the limiting rod 95, the sliding ring 96 can be limited, so that the sliding ring 96 can produce an effect of moving up and down on the outer surface of the limiting rod 95. By setting the second placing frame 98, the circuit board can be placed on the side away from the first placing frame 37, and the circuit board can be clamped tightly under the pull of the second spring 94.

[0020] An adjustable plug-in multilayer circuit board plug-in process comprises the following steps: Step 1: Place the sides of the multi-layer circuit board in the inner cavity of the first placement frame 37, and align the other side with the second placement frame 98. Under the pulling force of the second spring 94, the movable frame 93 drives the second placement frame 98 to move toward the multi-layer circuit board; Step 2: After both sides of the multilayer circuit board are respectively located in the inner cavities of the first placement frame 37 and the second placement frame 98, the motor 7 is connected to a power source and the switch of the motor 7 is turned on until the rotating rod 8 drives the threaded rod 55 to rotate; Step 3: During the rotation of the threaded rod 55, the first springs 510 between the multi-layer circuit boards will be squeezed and adapted to the upper surface of the first extrusion ring 57, and the corresponding threaded ring 54 will rotate on the outer surface of the threaded rod 55 until the elastic potential energy of multiple first springs 510 is the same. At this time, turn off the motor 7 to make the distance between the multi-layer circuit boards consistent.

[0021] Working principle: When in use, the operator places the sides of the multi-layer circuit board in the inner cavity of the first placement frame 37 respectively, and aligns the other side with the second placement frame 98. Under the pulling force of the second spring 94, the movable frame 93 drives the second placement frame 98 to move toward the multi-layer circuit board, and the track rod 99 also moves in the inner cavity of the limit ring 38, so that the circuit board is finally positioned. Then the motor 7 is connected to the power supply and the switch is turned on, so that the rotating rod 8 drives the threaded rod 55 to rotate. When the distance between the two circuit boards is too close, the first spring 510 will squeeze the first squeezing ring 57 on the top of the lower threaded ring 54, so that the two threaded rings 54 will be subjected to the upper and lower squeezing force, thereby causing the threaded ring 54 to rotate on the outer surface of the threaded rod 55, and finally changing the distance between the circuit boards. After that, the first spring 510 will no longer squeeze, so that the threaded ring 54 will rotate with the threaded rod 55, and will not move up and down on the outer surface of the threaded rod 55, and the connecting rod 52 will not rotate under the influence of the second sliding bearing 53.
