Description

PCB fixing support

[ technical field ] A method for producing a semiconductor device

The utility model relates to a circuit board technical field especially relates to a PCB board fixed bolster.

[ background of the invention ]

The PCB is also called a printed circuit board, and is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. It is called a "printed" circuit board because it is made using electronic printing. PCB boards have evolved from single-layer to double-sided, multi-layer, and flexible, and still maintain their respective trends. Due to the continuous development towards high precision, high density and high reliability, the volume is continuously reduced, the cost is reduced, and the performance is improved, so that the printed board still keeps strong vitality in the development engineering of future electronic equipment. In the process of processing the PCB, the PCB needs to go through a plurality of processes such as printing, etching, drilling and the like, and the PCB needs to be stored on the fixed support in the process of transferring the next process in one process.

In the prior art, most of PCB placing racks are fixed in size. However, in the production operation, multiple batches of PCBs with different sizes are often involved, and the PCB placement rack with a fixed size cannot meet the requirement of storing different batches of PCBs with different sizes.

The utility model discloses it is not enough to solve prior art and research and propose.

[ Utility model ] content

The utility model aims at overcoming the shortcoming of above-mentioned prior art, provide one kind and can be according to PCB board size regulation and place the PCB board fixed bolster of PCB board.

The utility model discloses can realize through following technical scheme:

the utility model discloses a PCB board fixed bolster, including base and bolt, base up end both sides all are fixed with the riser, be equipped with altitude mixture control hole on the riser, two still be equipped with the clamp plate in the middle of the riser, clamp plate and riser sliding connection, the riser is kept away from be equipped with the slider on the platen face, the slider both sides are fixed with the fixed column, the fixed column end penetrate the fixed slot that is equipped with on the aforementioned clamp plate and fixed column assorted, still be equipped with the fixed orifices on the slider, the bolt passes aforementioned fixed orifices and aforementioned altitude mixture control hole and aforementioned clamp plate screwed connection in proper order, the base up end still is fixed with fixed slot I, the terminal surface is fixed with fixed slot II under the clamp plate. The PCB is vertically placed between the pressing plate and the base, the pressing plate is moved up and down, after the PCB is fixed, the bolt is screwed down, the pressing plate is fixed, and the PCB is fixed on the fixing support. The use requirements of different batches of PCB boards with different sizes can be met by adjusting the distance between the fixed pressing plate and the base.

Preferably, the distance between the two fixed columns on the sliding block is equal to the length of the vertical plate. The pressure plate can be effectively prevented from inclining.

Preferably, the bolt is a butterfly bolt. The bolt can be screwed more conveniently.

Preferably, the pressure plate is arranged in parallel with the base.

Preferably, the fixing groove i is serrated.

Preferably, the fixing groove II is serrated.

Compared with the prior art, the utility model has the advantages that:

1. the requirement for placing PCBs of different sizes is achieved by adjusting the distance between the pressing plate and the base.

2. Through setting up butterfly bolt, more convenient is fixed slider and clamp plate.

3. The fixing groove I and the fixing groove II are in a sawtooth shape, and the requirement for placing the PCB with different thicknesses can be met.
