Description

Technical Field

[0001] The utility model relates to the field of printed circuit board manufacturing, in particular to an anti-warping positioning device for a thin printed circuit board. Background Art

[0002] Thin printed circuit boards are an important component of the electronics industry. Due to their thinner boards, thin printed circuit boards can effectively reduce the volume and weight of electronic equipment. With the trend of miniaturization, lightweight and high performance of electronic products, the demand for thin printed circuit boards is growing.

[0003] However, thin printed circuit boards also face some problems during the production process. For example, due to the thinness of the thin printed circuit boards, the front end and the corners on both sides of the front end of the thin printed circuit boards are prone to warping during transportation on the assembly line, especially the two corners at the front end of the thin printed circuit boards. After the front end and the corners on both sides of the thin printed circuit boards are warped, they are easily stuck in processing equipment such as conveying rollers, thereby causing the thin printed circuit boards to deform or break, affecting the normal production of thin printed circuit boards.

[0004] In view of the above problems, it is very necessary to study and design a positioning device that can prevent the front end and the corners on both sides of the front end of a thin printed circuit board from warping during transportation. Utility Model Content

[0005] The utility model aims to provide a thin printed circuit board anti-warping positioning device to solve at least one of the above technical problems.

[0006] According to one aspect of the utility model, there is provided an anti-warping positioning device for a thin printed circuit board, comprising:

[0007] A first positioning portion, the first positioning portion being provided with at least one first notch for clamping an edge of a thin printed circuit board; and

[0008] The second positioning part is provided with at least one second notch for clamping the edge of the thin printed circuit board, one end of the second positioning part is connected to one end of the first positioning part, and the first positioning part and the second positioning part are arranged vertically.

[0009] The anti-warping positioning device of the utility model can clamp the front edge of the thin printed circuit board into the first notch on the first positioning part, and clamp the side edge of the thin printed circuit board into the second notch on the second positioning part when the thin printed circuit board is conveyed on the assembly line. Since the first positioning part and the second positioning part are arranged vertically, the first positioning part and the second positioning part can be clamped on the two vertical edges of the thin printed circuit board respectively. In this way, the front end and the front end corner of the thin printed circuit board are clamped and fixed by the first positioning part and the second positioning part. During the conveying process, the front end and the front end corner of the thin printed circuit board will no longer have the problem of warping, so as to avoid the front end and the front end corner of the thin printed circuit board being clamped in the conveying roller and other processing equipment during the conveying process. The thickness of the first positioning part and the second positioning part is slightly larger than the thickness of the thin printed circuit board. In this way, the first notch of the first positioning part and the second notch of the second positioning part will not cause excessive bending damage to the edge of the thin printed circuit board.

[0010] Preferably, the first positioning portion includes a first straight wall, a first semicircular arc wall and a second straight wall connected in sequence, and the first notch is formed by enclosing the first straight wall, the first semicircular arc wall and the second straight wall connected in sequence.

[0011] Therefore, the inner wall of the first notch formed by the first straight wall, the first semicircular arc wall, and the second straight wall is smooth. When the edge of the thin printed circuit board is clamped in the first notch, the smooth inner wall of the first notch will not clamp the edge of the thin printed circuit board and will not cause damage to the edge of the thin printed circuit board.

[0012] Preferably, the first straight wall and the second straight wall are arranged in parallel.

[0013] Therefore, the first straight wall and the second straight wall arranged in parallel facilitate the edge of the thin printed circuit board to be clamped in the first notch, and also facilitate the edge of the thin printed circuit board to be removed from the first notch.

[0014] Preferably, the number of the first notches is three, and the three first notches are arranged at equal intervals along the length direction of the first positioning portion.

[0015] Therefore, the three first notches can clamp and fix the edge of the thin printed circuit board more stably.

[0016] Preferably, the second positioning portion includes a third straight wall, a second semicircular arc wall and a fourth straight wall connected in sequence, and the second gap is formed by enclosing the third straight wall, the second semicircular arc wall and the fourth straight wall connected in sequence.

[0017] Therefore, the inner wall of the second notch formed by the third straight wall, the second semicircular arc wall, and the fourth straight wall is smooth. When the edge of the thin printed circuit board is clamped in the second notch, the smooth inner wall of the second notch will not clamp the edge of the thin printed circuit board and will not cause damage to the edge of the thin printed circuit board.

[0018] Preferably, the third straight wall and the fourth straight wall are arranged in parallel.

[0019] Therefore, the third straight wall and the fourth straight wall arranged in parallel facilitate the edge of the thin printed circuit board to be clamped in the second notch, and also facilitate the edge of the thin printed circuit board to be removed from the second notch.

[0020] Preferably, the number of the second notches is three, and the three second notches are arranged at equal intervals along the length direction of the second positioning portion.

[0021] Therefore, the three second notches can clamp and fix the edge of the thin printed circuit board more stably.

[0022] Preferably, all corners of the first positioning portion are in an arc shape, and all corners of the second positioning portion are in an arc shape.

[0023] Therefore, in this case, during the process of installing the first positioning portion and the second positioning portion, it is possible to prevent the corner position of the first positioning portion and the corner position of the second positioning portion from causing damage to the thin printed circuit board.

[0024] Preferably, it further comprises a third notch, which is arranged at the connection position between the first positioning portion and the second positioning portion.

[0025] Therefore, the third notch located at the connection portion between the first positioning portion and the second positioning portion can clamp and fix the frontmost corner of the thin printed circuit board to prevent the frontmost corner of the thin printed circuit board from tilting.

[0026] Preferably, the first notch, the second notch and the third notch have the same shape.

[0027] The first notch is arranged perpendicularly to the long side of the first positioning portion,

[0028] The second notch is arranged perpendicularly to the long side of the second positioning portion,

[0029] The third notch is arranged at an angle of 45 degrees to the first notch or the second notch.

[0030] Therefore, the setting of the first notch, the second notch and the third notch can easily clip the edge and corner of the thin printed circuit board into the first notch, the second notch and the third notch, and also facilitate the edge and corner of the thin printed circuit board to be removed from the first notch, the second notch and the third notch.
