[ 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 fixing bracket, which comprises a bracket and a bolt, four corners of the upper end surface of the bracket are fixed with upright posts, a slide bar is fixed between the upright posts at two same sides, slide blocks which are connected with the slide bar in a sliding way are arranged on the slide bar, a spacing plate I is fixed between the two slide blocks, a plurality of spacing grooves I which are mutually fixed with the PCB are arranged on the spacing plate I, a spacing plate II is arranged on the two upright posts which are opposite to the spacing groove I on the spacing plate I, a spacing groove II which is corresponding to the spacing groove I is arranged on the spacing plate II, a supporting seat I is fixed between the two slide blocks below the spacing plate I, a plurality of positioning grooves I which are matched with the PCB are arranged on the supporting seat I, a supporting seat II is arranged in the middle of the upright post below the spacing plate II, a plurality of positioning grooves II, a through hole through which a bolt penetrates is formed in the upper portion of the sliding block, and the through hole through which the bolt penetrates on the sliding block and the through hole through which the sliding rod penetrates are mutually crossed. According to the position of PCB board adjusting slide of equidimension not on the slide bar, place the PCB board in corresponding constant head tank II and I top of constant head tank to fix through corresponding spacing groove I and spacing groove II, make the slider fixed through screwing up the bolt, realize placing the demand of the PCB board of equidimension not of different batches.

Preferably, a plurality of feet are fixed below the bracket. Through the lower margin is fixed, avoid the slope of PCB board or topple over.

Preferably, the bolt is a butterfly bolt. After the bolt is more conveniently screwed or unscrewed, the position of the sliding block is adjusted.

Preferably, the two slide bars are arranged in parallel.

Preferably, constant head tank I sets up the up end at supporting seat I.

Preferably, the positioning groove II is formed in the upper end face of the support seat II.

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

1. the slider moves on the slide bar, adjusts the distance between limiting plate I and the limiting plate II, realizes placing the demand of the PCB board of equidimension not.

2. Through setting up butterfly bolt, more convenient fix slider and slide bar.

3. Through setting up constant head tank I, constant head tank II, spacing groove I and spacing groove II, the effectual PCB board of having avoided moves on the fixed bolster, has avoided electronic component's on the PCB board damage.
