Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, in particular to a circuit board pressing mechanism. Background Art

[0002] Circuit board, also known as printed board for short, is one of the important components of the electronics industry. Almost every electronic device, from small electronic watches and calculators to large computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use circuit boards to make electrical interconnections between various components. At present, when producing printed circuit boards, it is necessary to press the circuit boards together through a pressing device. In the printed circuit board pressing process, stacking is a very important process. In order to ensure that the printed circuit board is evenly stressed during pressing, it is required that the printed circuit board must be placed in the middle of the steel plate during stacking. However, when stacking, existing personnel can only rely on their own experience and visual judgment to confirm whether it is placed in the middle of the steel plate, which wastes a lot of time and has poor accuracy, making it difficult to ensure the quality of the pressed circuit board. Therefore, a circuit board pressing mechanism is needed to improve the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a circuit board pressing mechanism, which solves the problem that when stacking boards, existing personnel can only rely on their own experience and visual judgment to confirm whether they are placed in the middle of the steel plate, which wastes a lot of time and has poor accuracy, making it difficult to ensure the quality of the pressed circuit boards.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circuit board pressing mechanism, comprising a pressing table, the pressing table is provided with four through holes, a movable rod is overlapped in the through holes, a movable plate is provided at one end of the movable rod, a fixed frame is provided under the pressing table, an electric push rod is provided in the fixed frame, a fixed block is provided at the output end of the electric push rod, four pin frames are provided on the side of the fixed block, and a connecting rod is hinged in the pin frame.

[0005] As a further solution of the utility model: a support frame is provided under the pressing table, and four universal wheels are provided under the support frame.

[0006] As a further solution of the utility model: a support frame is provided on the pressing table, a cylinder is provided in the support frame, and a pressing plate is provided at the output end of the cylinder.

[0007] As a further solution of the utility model: a fixing rod is provided at the other end of the movable rod, and the other end of the fixing rod is hinged to the connecting rod.

[0008] As a further solution of the utility model: a slide groove is provided in the through hole, and a slider is slidably connected in the slide groove.

[0009] As a further solution of the utility model: the sliding block is connected to the movable rod, and the movable plate is overlapped with the pressing table.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The circuit board pressing mechanism, by setting an electric push rod, a fixed block, a connecting rod, a movable rod and a movable plate, with the cooperation of the electric push rod, the fixed block, the connecting rod, the movable rod and the movable plate, further avoids the situation that the staff can only rely on their own experience and visual judgment to confirm whether it is placed in the middle of the steel plate. At the same time, only the electric push rod needs to be controlled to realize the four movable plates approaching each other, and automatically push the circuit board to be pressed to the middle position of the pressing table, which not only saves a lot of time and is simple to operate, but also further guarantees the quality of the circuit board.

[0012] 2. The circuit board pressing mechanism is provided with a slide groove and a slider. The slide groove supports and limits the slider, so that the slider slides smoothly in the slide groove, and the slider supports and limits the movable rod, further ensuring that the movable rod will not shake randomly during the movement in the perforation.

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-4As shown, the utility model provides a technical solution: a circuit board pressing mechanism, including a pressing platform 1, four through holes 6 are provided on the pressing platform 1, and the through holes 6 are provided to limit the movable rod 2, so that the movable rod 2 can move smoothly. The movable rod 2 is overlapped in the through holes 6, and a movable plate 15 is provided at one end of the movable rod 2. The movable plate 15 overlaps with the pressing platform 1, and a slide groove 13 is provided in the through hole 6. A slider 14 is slidably connected in the slide groove 13. By setting the slide groove 13 and The slider 14 and the slide groove 13 support and limit the slider 14, so that the slider 14 can slide smoothly in the slide groove 13. The slider 14 is connected to the movable rod 2. A fixed frame 10 is provided under the pressing table 1. An electric push rod 8 is provided in the fixed frame 10. A fixed block 16 is provided at the output end of the electric push rod 8. By setting the movable rod 2 and the fixed rod 12, the movable rod 2 supports and limits the fixed rod 12, thereby ensuring that the fixed rod 12 will not shake randomly during the movement.
