Technical field:
The utility model is related to speaker products technical fields, and in particular to the detection jig of the foam component used in speaker,
Refer in particular to a kind of special fixture for detecting the foam component with grenadine mesh.
Background technology:
Currently, speaker products to go out the foam component used at sound all be an entire double faced adhesive tape foam, foam and speaker
There is no gap after product fitting, this is easy for causing audio fruit bad, influences the quality of speaker.For this purpose, applicant has developed
A kind of foam component with grenadine opens up several stomatas on double faced adhesive tape foam surface and covers grenadine at stomata, can be with
Improve and audio fruit.And whether this product needs to detect grenadine fitting in place the qualitative factors such as whether to block for mesh, with
Exempt from leakage patch, partially patch occur or the problems such as plug-hole, based on detection at present is judged with artificial observation, the setting of ununified parameter,
Therefore efficiency is low and uniformity is bad.For this purpose, the applicant develops coordinates coherent detection software and journey using industrial camera again
Ordered pair grenadine mesh is detected, and in order to preferably improve detection efficiency and precision, correspondingly needs to develop positioning product
Detect jig.
Utility model content:
The purpose of the utility model is to overcome the above-mentioned shortcomings of the prior art, provide a kind of for detecting band grenadine net
The special fixture of the foam component in hole.
The technical solution adopted in the utility model is:It is a kind of to be controlled for detecting the special of the foam component with grenadine mesh
Tool, the special fixture include in the pedestal, center and cope plate for being from bottom to top sequentially stacked assembling, wherein the upper surface of pedestal,
A vessel is formed inside center and between cope plate lower surface, the LED light source of several dispersed placements is provided in the vessel;
A wire casing passed through for conducting wire is offered in an edge of center;The upper surface of the cope plate is equipped with and foam component to be detected
The corresponding workpiece concave surface of exterior contour, and in offering several loopholes through cope plate upper and lower surface in the workpiece concave surface,
The position of loophole and quantity are corresponding with the position of grenadine and quantity on foam component to be detected;In cope plate edge, center
Through-hole corresponding with position is offered at base edge respectively and screw hole, and fixed by screw locking.
A groove communicated with workpiece concave surface, and the depth of groove are offered in the workpiece concave surface peripheral region of cope plate
More than the depth of workpiece concave surface.
The depth of the workpiece concave surface is 0.5mm~1.5mm.
The quantity of the loophole is six, and light transmission bore dia is more than the diameter in grenadine hole in foam component to be detected.
In the circuit board, several wiring boards are layed in base upper surface and form LED light source square for the LED light source setting
Battle array.
The LED light source is green LED light source.
The utility model detection jig overall structure is simple, and compact is flexible, assembles and easy to operate, can improve foam
The detection efficiency and accuracy of detection of the grenadine mesh of component, and can slow down operating personnel's as light source using soft green light
Visual fatigue sense.

Fig. 2 is the floor map of center in the utility model;
Fig. 3 is the floor map of the utility model in the base;
Fig. 4 is the schematic diagram after the utility model assembling.
Specific implementation mode:
As Figure 1-Figure 4, described in the utility model is a kind of for detecting the special of the foam component with grenadine mesh
With jig, which includes in the pedestal 1, center 2 and cope plate 3 for being from bottom to top sequentially stacked assembling, wherein pedestal 1
Upper surface, form a vessel 100 between the inside of center 2 and 3 lower surface of cope plate, be provided in the vessel 100 several
The LED light source 4 of dispersed placement;A wire casing 21 passed through for conducting wire is offered in an edge of center 2;The wiring board of LED light source 4
Connect with conducting wire, conducting wire is pierced by by wire casing 21 and connect with external power supply driver, to give the power supply of LED light source 4;On described
The upper surface of template 3 is equipped with workpiece concave surface 31 corresponding with foam component exterior contour to be detected, and in the workpiece concave surface 31
Offer several loopholes 32 through 3 upper and lower surface of cope plate, the position of loophole 32 and quantity and foam component to be detected
The position of upper grenadine and quantity are corresponding;It is corresponding that position is offered respectively in 3 edge of cope plate, center 2 and 1 edge of pedestal
Through-hole and screw hole, and be locked by screw 5.
A groove communicated with workpiece concave surface 31 33 is offered in 31 peripheral region of workpiece concave surface of cope plate 3, and recessed
The depth of slot 33 is more than the depth of workpiece concave surface 31;The effect of the groove 33 is easy for being placed with hand and takes out and adjust to be checked
Survey foam component;
The depth of the workpiece concave surface 31 is 0.5mm~1.5mm.
The quantity of the loophole 32 be six, 32 diameter of loophole be more than foam component to be detected in grenadine hole it is straight
Diameter makes the luminous energy appeared that the range where grenadine be completely covered.
The LED light source 4 is arranged in assist side 41, several wiring boards 41 are layed in 1 upper surface of pedestal and form LED light
Source matrix keeps the brightness that loophole appears uniform, convenient for improving accuracy of detection.
The LED light source 4 is green LED light source, and green light is relatively soft, is stimulated human eye small.
The utility model detection jig overall structure is simple, and compact is flexible, assembles and easy to operate, can improve foam
The detection efficiency and accuracy of detection of the grenadine mesh of component, and can slow down operating personnel's as light source using soft green light
Visual fatigue sense.
It is understood that embodiment of above is merely to illustrate that the principles of the present invention and uses exemplary
Embodiment, however the utility model is not limited thereto.For those skilled in the art, this is not being departed from
In the case of the spirit and essence of utility model, various changes and modifications can be made therein, these variations and modifications are also considered as this reality
With novel protection domain.
