The implication of Reference numeral among the figure: the 1-sound proof box, 2-seals sponge, and 3-opens and closes cylinder, 4-product to be tested, 5-support plate, 6-needle plate, 7-audio-frequency generator, 8-support plate cylinder, 9-slide rail, air cylinder under the 10-, 11-marking pen, 12-cylinder, 13-fixed head.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
With reference to Fig. 1, a kind of audio-frequency test tool of the present invention comprises: the sound proof box 1 that opens and closes along the vertical direction, be arranged at the mechanism for testing of sound proof box 1 inside, be arranged at the mechanism for testing top, along automatic mark mechanism that X, Y, three directions of Z move.The below introduces respectively aforementioned each parts:
As a kind of preferred scheme, be provided with in the bilateral symmetry of sound proof box 1 and open and close cylinder 3, open and close the switching sound proof box 1 that cylinder 3 can be easily and fast, pick and place the time of product in the time of can shortening operation.
The mechanism for testing that is arranged at sound proof box 1 inside comprises: the support plate 5 that is used for carrying product 4 to be tested, the needle plates 6 that are used for fixed test probe that arrange corresponding to support plate 5, the audio-frequency generator 7 for generation of the sound of fixed-audio that is electrically connected with detector probe on the needle plate 6.Support plate 5 can adopt glass-fiber-plate to be processed into, and thickness can be satisfied the demand about 10mm.Audio-frequency generator 7 provide stable, a fixing voice signal can for product 4 to be tested, whether qualifiedly then tests product to be tested 4 by the size of this voice signal.
As a kind of preferred scheme, above-mentioned mechanism for testing also comprises: be used for to drive the support plate cylinder 8 that support plate 5 moves forward and backward, and the slide rail 9 that be arranged in parallel with support plate cylinder 8.Under the drive of support plate cylinder 8, support plate 5 slides along slide rail 9 front and back, thereby can adjust the front and back relative distance of product 4 to be tested in measurement jig, and then the flexibility that can improve measurement jig of the present invention.
As a kind of preferred scheme, above-mentioned mechanism for testing also comprises: lower air cylinder 10.Lower air cylinder 10 is fixedly connected with needle plate 6, is used for driving needle plate 6 and moves up and down, thereby the detector probe on the needle plate 6 is contacted with product 4 to be tested.In order to guarantee the stationarity of needle plate 6, lower air cylinder 10 can be set to 4, is separately positioned on the below at four angles of needle plate 6.Adopt lower air cylinder 10 to drive needle plate 6, can make needle plate 6 smooth, smooth moving up and down.
Automatic mark mechanism is arranged at the top of above-mentioned mechanism for testing, is used for making a mark to testing bad product, specifically realizes by its marking pen that comprises 11.In labeling process, marking pen 11 can be along the movement of X, Y, three directions of Z, specifically realize by three axle travel mechanisms, this three axles travel mechanism comprises: horizontally disposed and orthogonal X-axis moving assembly and y-axis shift move assembly, vertically the Z axis moving assembly of setting.X, Y, Z three axle moving assemblies include: base, be fixed in the CD-ROM drive motor on the base, the leading screw that is fixedly connected with CD-ROM drive motor, extends along the base length direction, the guided way that be arranged in parallel with leading screw, and the slide block that slides along guided way.Wherein, the base of Z axis moving assembly is fixedly connected with the slide block of X-axis moving assembly, and the base of X-axis moving assembly is fixedly connected with the slide block of the moving assembly of y-axis shift, that is to say, Z axis moving assembly integral body moves horizontally along X-axis, and X-axis moving assembly integral body moves horizontally along Y-axis.In addition, be fixed with fixed head 13 on the slide block of Z axis moving assembly, marking pen 11 is fixed on the fixed head 13, moves with the movement of three axle travel mechanisms.
As a kind of preferred scheme, marking pen 11 can move up and down on fixed head 13, is driven by the cylinder 12 that is fixedly installed on the fixed head 13.
Can be to testing the accurate mark of bad product by above-mentioned automatic mark mechanism, underproof product is recorded in convenient clearly sort out, can prevent from effectively, intuitively testing bad product and flow into the next stop.
For the accuracy that guarantees to test, in testing process, the position of audio-frequency generator 7 is not changeless, it remains on a certain fixed-direction of current tested soft board, directly over for example can current tested soft board, so for simplified structure, audio-frequency generator 7 is fixedly connected on the fixed head 13 with automatic mark mechanism, and move along X, Y, three directions of Z with it.
With reference to Fig. 1, the course of work of audio-frequency test tool of the present invention is: product 4 to be tested is placed on the support plate 5, press starting switch after, support plate 5 is moved to test position in the driving of cylinder 8, this moment, the switching cylinder 3 on sound proof box 1 both sides was also worked simultaneously, and sound proof box 1 is closed; After sound proof box 1 was closed, lower air cylinder 10 drove needle plate 6 and presses down, and makes detector probe touch product 4 to be tested, by the connection of detector probe, so that product is powered; After the pressing, audio-frequency generator 7 is under the drive of X, Y, Z axis moving assembly fully, and the soft board for the treatment of on the test products 4 is tested one by one; After soft board was all tested end, by record and the control of testing software, X, Y, Z axis moving assembly drove the position that marking pen 11 moves to each test failure product, carry out mark; After mark was all finished, X, Y, Z axis moving assembly were got back to the home position, and lower air cylinder 10 lifts, and support plate 5 is got back to the home position under the effect of cylinder 8, took out this moment and detected complete product, again put into the product that does not detect, so repeated work.
Need to prove above demonstration and described basic principle of the present invention and principal character.The technical staff of the industry should understand, and the present invention is not restricted to the described embodiments, and without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
