Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention。
Embodiment 1
As Figure 1-3, a kind of test chart, including film 1, bottom film 1, it is connected to horizontal base plate 2, horizontal base plate 2 connection bonding with film 1；
Film 1 is provided with fixed frame 3 away from the side of horizontal base plate 2, fixed frame 3 connection bonding with horizontal base plate 2。
A kind of test chart that above-described embodiment provides; during use; film 1 tiling is pasted onto on horizontal base plate 2; the flatness of horizontal base plate 2 ensure that the flatness of film 1; meanwhile, the edge at horizontal base plate 2 arranges fixed frame 3, and horizontal base plate 2 is played further protection effect by fixed frame 3; prevent it from the phenomenon of deformation occurring, and then avoid film 1 to deform。
, not easily there is the phenomenon of deformation in this test chart, it is ensured that the flatness of film 1, adopts the mode of fixed frame 3, and the target of needs fast, can be carried out, be replaced according to actual needs by installation, convenient fixing, replacing in advance, improves production efficiency。
Embodiment 2
As Figure 1-3, a kind of test chart, including film 1, bottom film 1, it is connected to horizontal base plate 2, horizontal base plate 2 connection bonding with film 1；
Film 1 is provided with fixed frame 3 away from the side of horizontal base plate 2, fixed frame 3 connection bonding with horizontal base plate 2。
Horizontal base plate 2 is horizontal steel mesh。
What steel mesh utilized is the steel mesh technology in SMT technique, and wherein, in SMT technique, the tension force for steel mesh has certain requirement。Therefore, in order to reach the tensile requirements of steel mesh in technique, steel mesh all can adopt the net that stretches tight to process, and steel mesh stretches tight after net process, has good levelness, thus ensure that the levelness of horizontal base plate 2, it is ensured that the flatness of film 1。
The internal diameter size of fixed frame 3 is not less than film 1 outside dimension。
Wherein, the shape of fixed frame 3 is general identical with the shape of film, preferably, fixed frame 3 be shaped as rectangle, film 1 is arranged on the middle part of fixed frame 3, and wherein, the optimum internal diameter size that mode is fixed frame 3 is identical with the outside dimension of film 1, when arranging fixed frame 3, not in the unnecessary space increasing other except fixed frame 3。
The material of fixed frame 3 is aluminium sheet or aluminium section bar。
By using the fixed frame 3 of aluminium sheet or aluminium section bar, its light weight, it is simple to the installation operation of test chart, and comparatively firm; it is not likely to produce deformation, therefore, the better effects if of protection steel mesh and film 1; meanwhile, aluminium sheet and aluminium section bar is less costly, it is possible to reduce input cost。
Time specifically used, test chart is arranged on the position that product is corresponding, when corresponding test chart changed by needs, take off another test chart of replacing, this kind of mode, without being opened by two blocks of glass again, is again changed new film 1, then is installed, simple to operate, quick, save the time。Simultaneously as it in use, is not the fixing device using identical film 1, therefore, it can make in advance the test chart of various criterion, further save the time, improve efficiency。
Embodiment 3
As Figure 1-3, the preparation method of a kind of test chart, comprise the following steps:
The prefabricated fixed frame of marginal adhesion at the steel mesh evened up, prefabricated fixed frame surrounds closure state；
At the film 1 that the surface configuration of steel mesh tiles, and by bonding with steel mesh for film 1；
The steel mesh at film 1 edge is sheared, wherein, the edge reserved part steel mesh of film 1；
Be adhesively fixed frame on reserved steel mesh, and fixed frame surrounds film 1；
Steel mesh beyond fixed frame is cut。
Steel mesh is undertaken evening up process by Stretching machine。
Steel wire, by evening up process, namely in Stretching machine work process, is tightened on frame, forms a steel mesh with level by steel mesh, and the Main Function of Stretching machine is the tension force arranging steel mesh, while adjusting tension force, it is ensured that the level of steel mesh。
Film 1 is laid in the center of prefabricated fixed frame。
In manufacturing process, by centrally disposed for film 1 place, it is not only convenient for processing and manufacturing, meanwhile, each uniform force of steel mesh, it can be ensured that the stability of its level。
Time specifically used, the a piece of test chart being slightly larger in dimension than film 1 is made by one piece of bigger steel mesh tightened, wherein, the purpose arranging prefabricated fixed frame on the steel mesh tightened is to ensure that the level of steel mesh, wherein, after bonding with steel mesh for film 1 connection, cut off the steel mesh of one piece of bigger about film 1 of size, wherein, film 1 is arranged on the core of this steel mesh, and this part still keeps level, afterwards, connect fixed frame again at its edge, and then define required smaller test chart。
When pre-setting the test chart of each model, the size according to film 1 reality, various sizes of fixed frame is set accordingly。The test chart of different size model is alone body one by one, in test process, it is possible to use immediately, has saved the time of Assembling debugging, thus improve work efficiency。
Know-why of the present utility model is described above in association with specific embodiment。These describe and are intended merely to explanation principle of the present utility model, and can not be construed to the restriction to this utility model protection domain by any way。Based on explanation herein, those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes fall within protection domain of the present utility model。
