Abstract
The utility model discloses a bracket used for printing a circuit board. The bracket comprises a bracket base plate (3) and is characterized in that bolt holes (2) are disposed on the four corners of the bracket base plate (3), that six component preformed holes (1) are disposed on central area of the bracket base plate (3), a milling area (4) is arranged among and around the six component preformed holes (1), that the bracket base plate (3) is a cube with inclined surfaces arranged on the four sides of the cube, and that the milling area (4) is milled in a stepped layered manner according to the shape of the circuit board. The bracket used for a printing a circuit board is simple in structure, firm to fix, and easy to manipulate.
Description
Technical field
The utility model relates to a kind of bracket, relates in particular to a kind of bracket for circuit board printing.
Background technology
In recent years, along with social progress, the development of science and technology, the circuit board of various uses is of a great variety, and quantity increases, because volume is more and more less, thinner, in actual circuit board printing operation, be easily out of shape, be not easy to the operation of print solder paste, traditional bracket in use, easily displacement, in the process of device, circuit board, can be because of irregular of circuit board, cause circuit board to set level, affect the operational quality of circuit board print solder paste.
Utility model content
In order to overcome the defect of above-mentioned prior art, the utility model provides simple in structure, fixed, easy to operate a kind of bracket for circuit board printing.
In order to achieve the above object, the utility model is realized by following scheme, a kind of bracket for circuit board printing, comprise: tray plate, it is characterized in that: four corners of tray plate are provided with dormant bolt hole, and tray plate zone line is provided with six components and parts preformed holes, between components and parts preformed hole and around be provided with milling dead zone, described tray plate is that surrounding is established bevelled square body, and described milling dead zone thickness adopts notch cuttype layering milling sky according to circuit board shape.
The utility model can be found out in sum, it is the square body of tapered plane that tray plate adopts surrounding, bottom can be wedged into fixed mount, increase the stability of bracket, for bracket can be positioned on fixed mount, surrounding arranges dormant bolt hole in the above, the setting in dormant bolt hole can not hinder bracket printing process, and in order to guarantee the evenness of circuit board on bracket, this sound construction is reliable, can not cause displacement, evenness can guarantee circuit board printing time,, there will not be many tin or few tin phenomenon, guarantee the uniformity of print solder paste, guarantee press quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein: 1, components and parts preformed hole; 2, dormant bolt hole; 3, tray plate; 4, milling dead zone.
Embodiment
As shown in the figure, a kind of bracket for circuit board printing, comprise: tray plate 3, it is characterized in that: 3 four corners of tray plate are provided with dormant bolt hole 2, tray plate 3 zone lines are provided with six components and parts preformed holes 1, between components and parts preformed hole 1 and around be provided with milling dead zone 4, described tray plate 3 is that surrounding is established bevelled square body, described milling dead zone 4 thickness adopt notch cuttype layering milling sky according to circuit board shape.
The utility model is to implement like this, carry out successively following operation: by square body supporting plate underframe 3, surrounding is arranged to tapered plane and is easy to be fixed, respectively establish a dormant bolt hole 2 in the surrounding of tray plate 3 upper ends, after bolt enters into dormant bolt hole 2 and is connected and fixed, bolt head can be in the inside in dormant bolt hole 2, the printing that can not affect supporting plate underframe 3 is used, in the middle of tray plate 3, be provided with circuit board element preformed hole 1, components and parts on circuit board are installed in components and parts preformed hole 1, in order to guarantee to coincide with fixing between circuit board and bracket, according to the feature of the high low layer of circuit board, become milling dead zone 4 in tray plate 3 higher slice millings.
Can find out by above embodiment, the utility model can be fixed supporting plate underframe, guarantee the feature of circuit board evenness on bracket.
Above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in claim scope of the present utility model.
Claims (3)
