Fig. 1 is the structural representation of a specific embodiment of audio test fixture of the present invention;
The implication of Reference numeral in figure: 1-sound proof box, 2-seals sponge, 3-opening and closing 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 10-, 11-marking pen, 12-cylinder, 13-fixed head.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
With reference to Fig. 1, a kind of audio test fixture of the present invention comprises: the sound proof box 1 of opening and closing along the vertical direction, is arranged at the mechanism for testing of sound proof box 1 inside, be arranged at above mechanism for testing, along the automatic mark mechanism of X, Y, Z tri-direction movements.Introduce former components respectively below:
Sound proof box 1 comprises upper and lower two parts, can opening and closing along the vertical direction, and in order to shield the interference of external sound, improve the accuracy of test, sound proof box 1 is made by aluminum alloy materials, and is provided with sealing sponge 2 at closed place.
As the preferred scheme of one, the bilateral symmetry of sound proof box 1 is provided with opening and closing cylinder 3, opening and closing cylinder 3 can opening and closing sound proof box 1 easily and fast, picks and places the time of product when can shorten operation.
The mechanism for testing being arranged at sound proof box 1 inside comprises: for carrying the support plate 5 of product 4 to be tested, the needle plate 6 for fixed test probe that arrange corresponding to support plate 5, the audio-frequency generator 7 of the sound for generation of fixed-audio be electrically connected with detector probe on needle plate 6.Support plate 5 can adopt glass-fiber-plate to be processed into, and thickness can be satisfied the demand at about 10mm.Audio-frequency generator 7 provides a voice signal stablized, fix can to product 4 to be tested, whether qualifiedly then tests product 4 to be tested by the size of this voice signal.
As the preferred scheme of one, above-mentioned mechanism for testing also comprises: for the support plate cylinder 8 driving support plate 5 movable, and the slide rail 9 be arranged in parallel with support plate cylinder 8.Under the drive of support plate cylinder 8, support plate 5 along slide rail 9 slide anteroposterior, thus can adjust the front and back relative distance of product 4 to be tested in measurement jig, and then can improve the flexibility of measurement jig of the present invention.
As the preferred scheme of one, above-mentioned mechanism for testing also comprises: lower air cylinder 10.Lower air cylinder 10 is fixedly connected with needle plate 6, for driving needle plate 6 to move up and down, thus the detector probe on needle plate 6 is contacted with product 4 to be tested.In order to ensure 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, smooth, smooth the moving up and down of needle plate 6 can be made.
Automatic mark organization establishes, in the top of above-mentioned mechanism for testing, for making a mark to the bad product of test, realizes particular by its marking pen 11 comprised.In labeling process, marking pen 11 can along the movement in X, Y, Z tri-directions, realize particular by three axle travel mechanisms, this three axles travel mechanism comprises: horizontally disposed and orthogonal X-axis moving assembly and Y-axis moving assembly, the Z axis moving assembly vertically arranged.X, Y, Z tri-axle moving assembly include: base, be fixed on the CD-ROM drive motor on base, be fixedly connected with CD-ROM drive motor, along base length direction extend leading screw, the guided way be arranged in parallel with leading screw, and along guided way slide slide block.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 Y-axis moving assembly, that is, Z axis moving assembly entirety moves horizontally along X-axis, and X-axis moving assembly entirety moves horizontally along Y-axis.In addition, the slide block of Z axis moving assembly is fixed with fixed head 13, marking pen 11 is fixed on fixed head 13, mobile with the movement of three axle travel mechanisms.
As the preferred scheme of one, marking pen 11 can move up and down on fixed head 13, is driven by the cylinder 12 be fixedly installed on fixed head 13.
By the product accurate marker that above-mentioned automatic mark mechanism can be bad to test, the convenient clearly underproof product of sort out record, can prevent testing bad product effectively, intuitively and flow into the next stop.
In order to ensure the accuracy of testing, 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, such as can directly over current tested soft board, so in order to simplified structure, audio-frequency generator 7 is fixedly connected on fixed head 13 together with automatic mark mechanism, and moves along X, Y, Z tri-directions with it.
With reference to Fig. 1, the course of work of audio test fixture of the present invention is: be placed on support plate 5 by product 4 to be tested, and after pressing starting switch, support plate 5 is moved to test position in the driving of cylinder 8, now the opening and closing cylinder 3 on sound proof box 1 both sides also works simultaneously, is closed by sound proof box 1; After sound proof box 1 is closed, lower air cylinder 10 drives needle plate 6 to press down, and makes detector probe touch product 4 to be tested, by the connection of detector probe, product is powered; After complete pressing, audio-frequency generator 7 is under the drive of X, Y, Z axis moving assembly, and the soft board treated on test products 4 is tested one by one; After soft board is all tested and terminated, by record and the control of testing software, X, Y, Z axis moving assembly drives marking pen 11 to move to the position of each test failure product, marks; After mark all completes, X, Y, Z axis moving assembly gets back to home position, and lower air cylinder 10 lifts, and support plate 5 gets back to home position under the effect of cylinder 8, now takes out and detects complete product, again put into the product do not detected, repeated work like this.
It should be noted that, above display and describe general 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.Application claims protection range is defined by appending claims and equivalent thereof.
