Description

Technical Field

[0001] The invention relates to the field of jigs, and in particular to a laying aid device for assembling fasteners of printed circuit boards. Background Art

[0002] At present, when producing printed circuit boards that require the use of fasteners to assemble components, operators are often required to stand the printed circuit boards upright, hold a sleeve to fix nuts and washers in one hand, and hold an electric screwdriver in the other hand to tighten the screws.

[0003] This method is acceptable for fastening a small number of printed circuit board products, but when it comes to processing large quantities of the same type of printed circuit boards, this operation is not only inconvenient and affects efficiency, but also brings hidden dangers of slipping and inadequate locking in the fastening process.

[0004] Although some prior art views provide some jigs to place the printed circuit board to avoid standing the printed circuit board upright, these jigs cannot protect the components that have been soldered on the printed circuit board, and it is not convenient to remove the printed circuit board after fastening. Summary of the invention

[0005] The purpose of the present invention is to provide a laying auxiliary device for assembling fasteners for printed circuit boards. By setting up a three-layer structure, combining springs and pads, as well as nut lifting pins, the printed circuit board can be easily lifted up. In addition, by designing a component avoidance groove on the placement plate, damage to the components that have been soldered on the printed circuit board can be avoided, thereby making the arrangement of the process more flexible.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A laying aid device for fastener assembly of printed circuit boards, comprising:

[0032] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0033] A laying aid device for fastener assembly of printed circuit boards, comprising:

[0034] A base 8 and a plurality of bottom plate columns 7, one end of the bottom plate column 7 is connected to the base 8;

[0035] A partition 6 and a plurality of movable pads 4 arranged on the partition, the bottom of the partition 6 is connected to the other end of the bottom plate column 7, and a first gap is formed between the partition 6 and the base 8, and the partition is provided with a plurality of first through holes 6-1 and a plurality of nut top pins 5, and the nut top pins 5 are fixed to the top of the partition 6;

[0036] A placement plate 1 and a plurality of fixing columns 10 are arranged at the bottom of the placement plate 1, wherein the upper ends of the fixing columns 10 are fixed on the placement plate 1, and the lower ends are arranged to align with the first through holes 6-1, and a spring is sleeved on the fixing columns 10, and a second through hole 1-1 for the nut push pin 5 to pass through is provided on the placement plate 1, and the placement plate 1 is provided with a device avoidance groove 1-2 and a nut limit block 2.

[0037] By setting up a three-layer structure, combining springs and pads, as well as nut lift pins 5, the printed circuit board can be easily lifted up. In addition, by designing component avoidance grooves 1-2 on the placement plate 1, damage to components that have been soldered on the printed circuit board can be avoided, thereby making the arrangement of the process more flexible.

[0038] A nut limit block 2 is set on the placement plate, and the nut and gasket are placed in advance to avoid the action of fixing with a sleeve. The printed circuit board can be laid flat for work, which improves production efficiency and reduces the phenomenon of slipping caused by the different axes of the electric screwdriver, screws and nuts.

[0039] In some embodiments, the pad 4 is rotatably mounted on the partition 6 via a rotating shaft, and the projection of the rotating shaft on the partition 6 is outside the projection area of ​​the placement plate 1 on the partition 6. In the rotation stroke of the pad 4, there is at least one position where the projection area of ​​the pad 4 on the partition 6 and the projection area of ​​the placement plate 1 on the partition 6 overlap, and there is at least another position where the projection of the pad 4 on the partition 6 is outside the projection area of ​​the placement plate 1 on the partition 6. By setting the pad 4 to be rotatable, the convenience of use can be improved. When performing the tightening operation, a part of the pad 4 is screwed into the placement plate 1 for support, thereby improving the stability during the tightening operation. When the printed circuit board needs to be removed, the pad 4 can be completely screwed out, so that the printed circuit board can be removed by pressing down the placement plate 1. In this process, since the nut top pin 5 will pass through the second through hole 1-1 on the placement plate 1 to support the printed circuit board, it can have the effect of lifting the printed circuit board. Of course, in other embodiments, other methods can also be used, such as manually moving the pad 4.

[0040] In some embodiments, a magnet 9 is further provided on the partition 6, and a soft magnet is provided at the bottom of the pad 4. When the magnet 9 adsorbs the soft magnet, the projection of the pad 4 on the partition 6 is outside the projection area of ​​the placement plate 1 on the partition 6. The design of the magnet 9 can play a fixing function when the pad 4 rotates. Of course, in other embodiments, other methods such as snaps can be used for fixing.

[0041] In addition, in some embodiments, a positioning pin 3 is also provided on the top of the placement plate 1. By providing the positioning pin 3, it is possible to avoid unsmooth board placement due to misalignment between the pin holes of the printed circuit board and the pins of the components to be fastened. In some of the embodiments, the positioning pin 3 is slidably provided on the placement plate 1, so that it can be suitable for products of different specifications.

[0042] In addition, in this embodiment, the partition 6 and the base 8 are arranged in parallel, and the partition 6 and the bottom plate column 7 are arranged vertically. Such a design can reduce the material consumption, improve the flatness, and thus improve the comfort of operation.

[0043] In addition, in this embodiment, the nut push pin 5 and the placement plate 1 are vertically arranged, which can reduce the material consumption.

[0044] In this embodiment, the placement plate 1 and the partition plate 6 are arranged in parallel, which can improve the flatness and thus improve the comfort of operation.

[0045] In this embodiment, the fixing column 10 and the placement plate 1 are vertically arranged, which can reduce the material consumption.

[0046] In this embodiment, a rubber piece is provided on the top of the nut ejector pin 5, which can effectively protect the printed circuit board.
