Examples
The embodiment of the application provides a soldering flux spraying uniformity testing method which comprises the step of spraying soldering flux on a testing piece. And then observing the color distribution condition on the test piece sprayed with the soldering flux, if the color distribution on the test piece is uniform, uniformly spraying the soldering flux. Whether the spraying of the soldering flux is uniform or not is judged by observing whether the color distribution on the test piece sprayed with the soldering flux is uniform or not, the test method is simple, the result of whether the soldering flux is uniformly sprayed or not is obtained simply, and the uniformity judgment is simple and visual.
Generally, a nozzle of a soldering flux spraying device forms a covering area at a position to be welded, the covering area is similar to the shape of an outlet of the nozzle, for example, the outlet of the nozzle of the soldering flux spraying device is rectangular, the covering area of the soldering flux sprayed out from the nozzle at the position to be welded is approximately rectangular, when the soldering flux is sprayed on a test piece through the nozzle, an approximately rectangular area with colors is normally presented on the test piece, whether the color distribution area on the test piece due to spraying of the soldering flux is approximately rectangular or not is observed, and whether the color distribution inside the color area is uniform or not is observed, if the color distribution area is approximately consistent with the shape of the nozzle of the soldering flux spraying device and the color distribution inside the color area is uniform, the soldering flux is uniformly sprayed. Of course, other types of flux nozzles for flux, such as a nozzle with a circular outlet, may also be used with similar determination methods, and are not described herein again.
One of the functions of the flux is to remove oxides on the metal surface and ensure firm connection of the welding spots, so the flux generally has certain acidity. In this embodiment, since the soldering flux is an acidic soldering flux, the soldering flux is sprayed on the test piece, and the soldering flux is sprayed on the alkaline test piece. The acid soldering flux and the alkaline test piece can generate acid-base reaction, corresponding colors are shown on the test piece, the spraying uniformity condition of the soldering flux is judged according to the distribution condition of the colors, the operation is simple and easy, the test piece capable of generating the acid-base reaction is easy to obtain, and the cost is low. The soldering fluxes with different components and different acidity need to be matched with test pieces with different components and different alkalinity for acid-base reaction.
In this embodiment, the method for testing the flux spraying uniformity further includes attaching a test solution to the receiving member to form a test piece. Therefore, the alkaline test piece refers to a test piece to which a test solution exhibiting alkalinity is attached. Through the test solution which is attached to the bearing piece and can change color after being contacted with the soldering flux, the test range can be conveniently and reasonably arranged on the bearing piece according to the spraying range of the soldering flux, and the waste of the test solution is avoided.
The test solution may be attached to the receiving member to form the test member by immersing the receiving member in the test solution. The bearing piece is soaked in the testing solution so that the testing solution is attached to the bearing piece to form the testing piece, the testing piece is formed simply, and the size of a testing area and the size of the testing area formed by different soaking areas are different, so that a user can conveniently and reasonably control the testing area as required.
In this embodiment, the test piece is a test paper. Namely, the bearing piece is a paper piece, and the paper piece is soaked in the test solution so that the test solution is attached to the paper piece to form the paper test piece. The paper test piece, and light in weight, it is with low costs, be convenient for accomodate.
In other embodiments, the receiving member may be a thin wooden plate, a plastic plate, or the like. In other embodiments, the test solution may be applied to the bearing surface by coating.
In this embodiment, the part of the test piece covered by the soldering flux is yellow, and the spraying uniformity of the soldering flux is judged according to the yellow distribution condition. Some flux materials have a color, such as flux materials with rosin as a major component, which is yellow or yellow. When the soldering flux with the color is sprayed on the test piece, the distribution condition of the color of the soldering flux on the test piece can be utilized to judge the spraying uniformity of the soldering flux, so that the test piece can be free from other test solutions which react with the soldering flux, and whether the soldering flux is uniformly sprayed can be judged according to the color of the soldering flux on the test piece, namely the test piece is a common plate or a paper piece. Of course, for some colorless soldering fluxes, the uniformity of the color distribution exhibited by the reaction of the soldering flux and the test solution on the test piece is still required to judge the uniformity of the spraying of the soldering flux.
In this embodiment, in the process of spraying the soldering flux on the test piece, the spraying direction of the soldering flux is perpendicular to the plane of the test piece. The spraying direction of the soldering flux is perpendicular to the plane of the test piece, so that the soldering flux is sprayed to the test piece, the test piece can receive all the sprayed soldering flux, and the uniformity distribution condition obtained by testing is more accurate.
In the actual production process, in order to reduce the usage amount of the soldering flux and increase the coverage area of the soldering flux, the soldering flux is generally sprayed in an atomized form by a soldering flux spraying device, and therefore, the method for testing the spraying uniformity of the soldering flux further comprises the step of judging the spraying uniformity of the atomized soldering flux according to the size of color spots on a test piece on which the soldering flux is sprayed. The atomized soldering flux forms a plurality of fine particles, after the granular soldering flux is contacted with a test piece, color spots which are adaptive to the size of the granular soldering flux can be formed on the test piece, the spraying uniformity of the soldering flux can be judged according to the distribution condition of each color spot, and whether the atomization of the soldering flux is uniform can also be judged according to the size condition of each color spot.
In some cases, the flux cannot be directly sprayed to the position to be welded by the flux spraying device, and a guide device or an air blowing device is required to change the flow direction of the flux sprayed from a nozzle of the flux spraying device so that the flux can be sprayed toward the position to be welded.
In this embodiment, the test piece is disposed on the blowing path of the blowing device, and the soldering flux sprayed from the soldering flux spraying device is blown onto the test piece by the blowing device. The testing piece is arranged on the blowing path of the blowing device, so that whether the soldering flux blown by the blowing device is uniformly distributed can be tested. Wherein, the blowing direction of the blowing device is vertical to the spraying direction of the soldering flux spraying device. The blowing direction of the blowing device is perpendicular to the spraying direction of the soldering flux spraying device, so that soldering flux can be comprehensively tested vertically, and the soldering flux is prevented from being deposited under the influence of gravity to influence the testing effect.
In other embodiments, the flowing direction of the soldering flux is changed by the guiding device, and the testing piece is placed on the guiding path of the guiding device, and the flowing direction of the soldering flux guided by the guiding device is perpendicular to the plane of the testing piece.
In some embodiments, the soldering flux is directly sprayed to the position to be welded through the soldering flux spraying device, the flowing direction of the soldering flux is not required to be changed by the air blowing device or the guiding device, the test piece is placed on the spraying path of the soldering flux spraying device, and the spraying direction of the soldering flux spraying device is perpendicular to the plane of the test piece.
As shown in fig. 1, a schematic diagram of an apparatus for changing the flow direction of the flux sprayed from the flux spraying apparatus 10 by the air blowing apparatus 20 is shown, the spraying direction a of the flux spraying apparatus is in the horizontal direction, the air blowing direction B of the air blowing apparatus is in the vertical direction, the nozzle 11 of the flux spraying apparatus 10 is located above the air outlet of the air blowing pipe 21 of the air blowing apparatus 20, and the test piece 30 is placed above the flux spraying apparatus 10 and on the air blowing path of the air blowing apparatus 20. After the nozzle 11 of the soldering flux spraying device 10 sprays the atomized soldering flux, the air blowing device 20 can blow the atomized soldering flux particles to the test piece 30, and whether the soldering flux is uniformly distributed is judged by observing the distribution condition of the colors on the test piece 30. If the color distribution on the test piece 30 is uniform, it indicates that the spraying of the soldering flux is uniform, and if the color distribution on the test piece 30 is non-uniform, it indicates that the air blowing device 20 cannot uniformly blow the soldering flux to the position to be welded (the distribution of the soldering flux is changed during the blowing process) and/or the soldering flux spraying device 10 does not uniformly spray the soldering flux.
Moreover, after the granular soldering flux contacts the test piece 30, color spots which are adaptive to the size of the granular soldering flux are formed on the test piece 30, the spraying uniformity of the soldering flux can be judged according to the distribution condition of each color spot, and whether the soldering flux is atomized uniformly (whether the size of the soldering flux particles formed by atomization is uniform) can also be judged according to the size condition of each color spot. If the color spots on the test piece 30 are not uniform in size, and the test soldering flux is sprayed from the soldering flux spraying device 10 uniformly, it indicates that the soldering flux is condensed during the process of blowing the atomized soldering flux by the air blowing device 20, so that the size of the soldering flux particles reaching the test piece 30 is not uniform. If the color spots on the test piece 30 are not uniform in size and whether the atomization of the soldering flux sprayed from the soldering flux spraying device 10 is uniform or not is not tested, it is required to test whether the atomization of the soldering flux sprayed from the soldering flux spraying device 10 is uniform or not first and then determine which link of the soldering flux spraying device and the air blowing device causes the atomization to be non-uniform.
It should be noted that the position of the test piece 30 can simulate the position to be welded during actual welding, so as to ensure that the uniformity testing method can guide actual production.
The improved uniformity in the embodiments of the present application does not necessarily mean absolute uniformity, and the color distribution may be considered to be uniformly distributed as long as there is no significant gap in the color distribution and the difference in the ideal state is large. The color spots are considered to be uniform in size as long as the difference in size between the respective color spots is not significant.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
