Abstract
The invention discloses a spraying test jig and a method, wherein, the testing jig comprises a jig panel which is provided with a plurality of gaps which pass through the jig panel for facilitating spraying, a testing panel which can be fixedly placed at the gaps during the testing process and cover the gaps, the spray is sprayed on the surface of the testing panel by the gaps; simultaneously, the testing method utilizes the testing jig for spraying and obtains the spray quantity of the spraying test by weighing the weights of the testing panel before and after the spray; furthermore, the spray area is measured after spraying, thus calculating the uniformity; and the testing jig and the testing method can obtain good testing effect.
Description
Technical field
The present invention relates to a kind of measurement jig method, particularly relate to a kind of spray amount, uniformity coefficient measurement jig and method.
Background technology
Before welding, use spray pattern usually, the metal surface spraying one deck scaling powder (FLUX) welding to remove the oxidation on metal surface layer, reaches better welding effect.And be the spray amount of control scaling powder, need spraying uniformity coefficient (unit area spray amount) be tested usually, prevent excessive spraying.
The existing FLUX spraying weight tool of measuring wave soldering in market, but unified specification do not had, all be that each company makes to measure at the wave soldering stove of self.And the instrument of absorption FLUX is also had nothing in common with each other when measuring, and measures also to have deviation.
At present, the adsorption tool of the FLUX uniformity coefficient use of industry measurement wave soldering generally adopts: a. facsimile transmission paper b. glass; The mode of these two kinds of instruments all is to judge from the surface: simple mode with range estimation, FLUX is residual just to be thought can't confirm use amount and the uniformity coefficient of FLUX uniformly as long as have in spread of spray, easily causes waste or failure welding.
Summary of the invention
The objective of the invention is to propose a kind of spray amount of accurate measurement spray test, the tool and the method for spraying uniformity coefficient, solved spray inhomogeneous waste that causes or failure welding.
Technical scheme of the present invention is: a kind of spray test fixture, and this comprises:
One tool panel, it is provided with the some breach that penetrate the tool panel, and this kind breach is established for convenient spraying;
One test panel, but its fixed placement in test covers this breach at this kind gap position; Spraying sprays to this test panel surface by breach; This kind test panel can be provided with many groups by corresponding breach, can organize simultaneously to spray more, is convenient to obtain test result.
The formation of above-mentioned breach can be: offer the hole, hole on this tool panel, there is perforation in the hole at the bottom of the hole, and this perforation penetrates this tool panel and forms breach; This kind test panel can be placed and be fixed in this hole, hole, and expose by breach on the test panel surface, and convenient spraying is carried out.
The invention allows for a kind of spray test method, this method comprises the steps:
A. take by weighing out the weight of test panel;
B. test panel is fixed on the measurement jig and sprays;
C. getting test panel takes by weighing weight once more and measures the spraying area;
D. calculate the spraying uniformity coefficient.
This method takes by weighing test panel weight twice by the spraying front and back, obtains the spray amount (i.e. the difference of twice weight) of spray test, measures the spraying area simultaneously after spraying, and utilize: uniformity coefficient=spray amount/spraying area calculates uniformity coefficient again; Make more science, more accurate of measurement result.

Embodiment
Below in conjunction with accompanying drawing in detail embodiments of the invention are described in detail.
As shown in Figure 1, a kind of spray test fixture, this comprises: a tool panel 10, it offers hole 100,9 holes on this tool panel 10, and, there is perforation at 100 ends of hole, hole, and this perforation penetrates this tool panel 10 and forms breach 110; This kind breach 110 is established for conveniently carrying out wave soldering FLUX spraying before;
One test panel 20, it is a sheet metal, fixed placement is in this hole 100, hole in test, cover this breach 110, because breach 110 areas are less than hole, hole 100 areas, and test panel 20 areas fall between, and make test panel 20 can not drop and be limited to from breach 110 and cheat the hole 100; Expose by breach 110 on test panel 20 surfaces, and convenient spraying is carried out (as shown in Figure 2).
This test panel 20 is whole to cover breach 110, prevents that spraying from leaking and waste raw material; Spraying sprays to this test panel 20 surfaces by breach 110; This kind test panel 20 can be provided with 9 groups by corresponding breach 110, can 9 groups sprays simultaneously, can make more science, more accurate of the test result that obtains.
Simultaneously, at these hole, hole 100 other cover plates 120 that are articulated with, this cover plate 120 is rotatable; And 100 other corresponding cover plates 120 are articulated with a briquetting 30 by screw 40 in the hole, hole, and this briquetting 30 can be around screw 40 rotations; In when test, this cover plate 120 can cover and fix this test panel 20, and is by rotation briquetting 30 that cover plate 120 compactings are fixing, can make test panel 20 surfacings; After the test, open cover plate 120 after briquetting 30 can being left, take out test panel 20, measure and calculate spray amount and uniformity coefficient through spraying.
As shown in Figure 3, a kind of spray test method, this method comprises the steps:
A. take by weighing out the weight of test panel 20;
Utilize the high precision balance of the high precision balance of degree of accuracy ten thousand/gram, weigh weight as the sheet metal of test panel 20;
C. getting test panel 20 takes by weighing weight once more and measures the spraying area;
After spraying is finished, open the cover plate 120 on this tool panel 10, take out the test panel 20 of spraying, utilize these test panel 20 weight of high precision balance weighing once more, simultaneously, measure spraying area actual on the test panel 20 (this spraying area approximates breach 110 areas of tool panel 10 usually).
D. calculate the spraying uniformity coefficient.
Utilize: uniformity coefficient=spray amount/spraying area, obtain the spraying uniformity coefficient; Wherein this spray amount is, test panel 20 weight that take by weighing in test panel 20 weight that take by weighing in the c step and a step poor.
Simultaneously, can draw more accurate data by analyzing the test result of many groups.
