Description

A PCBA fixture

technical field

The utility model relates to a PCBA fixture.

Background technique

The Chinese name of PCB is printed circuit board, which is the support body of electronic components. Before the appearance of PCB, the interconnection between electronic components was directly completed by wires. After the appearance of PCB, electronic components were integrated on a substrate. After electronic equipment adopts printed boards, due to the consistency of similar printed boards, errors in manual wiring are avoided, and automatic insertion or placement of electronic components, automatic soldering, and automatic detection can be realized to ensure the quality of electronic equipment. Improve labor productivity, reduce costs, and facilitate maintenance.

Printed boards have developed from single-layer to double-sided, multi-layer and flexible, and still maintain their own development trends. Due to the continuous development of high precision, high density and high reliability, continuous reduction in size, cost reduction and performance improvement, printed boards still maintain strong vitality in the development of future electronic equipment.

Usually, PCB empty boards are used in electrical equipment after being made into PCBA after SMT loading and then DIP plug-in. After the DIP plug-in, the board needs to be heated in a reflow furnace. At present, factories generally use manual hand pressing to press parts one by one after the DIP plug-in, which not only consumes more manpower, but also often causes parts to be pressed incorrectly, and there will be warping boards after the furnace and other undesirable phenomena.

In view of the above-mentioned defects, the designer is actively researching and innovating in order to create a PCBA fixture with a new structure, so that it has more industrial use value.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide a PCBA fixture.

The technical scheme of the utility model is as follows:

A PCBA fixture, including a PCBA board, the left and right sides of the PCBA board are provided with a first movable guide rod and a second movable guide rod, and the first movable guide rod and the second movable guide rod are provided with a pressure plate, and its features In that: the pressing plate is provided with a plurality of hanging rings, and the hanging ring is equipped with a pressing piece assembly, and the pressing piece assembly is composed of a hook fixed on the hanging ring, an upper connecting block connecting the hook, and a The elastic device on the upper connecting block, the lower connecting block arranged at the lower end of the elastic device, and the parts arranged under the lower connecting block are composed.

Further, the elastic device is a spring.

Further, the first movable guide rod also includes an upper column of the first movable rod and a lower column of the first movable rod, wherein the upper column of the first movable rod is fixed on the pressing plate, and the lower column of the first movable rod placed on the PCBA board.

By means of the above scheme, the utility model has at least the following advantages:

The utility model can press a plurality of components on the PCB board at one time, greatly reduces the manpower for pressing the parts, and the pressing parts are precisely in place without causing bad phenomena. The utility model can not only strengthen the connection between the parts and the board, but also not cause excessive pressure to damage the parts. As long as the elastic plate is pressed hard once, multiple parts can be pressed, and the working efficiency is greatly improved.

The above description is only an overview of the technical solution of the utility model. In order to understand the technical means of the utility model more clearly and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiment of the utility model with accompanying drawings. rear.
