Whether the rigging position relation between part housing 20 is qualified.
According to electric capacity calculation formula：Wherein ε is constant, and k is electrostatic force constant, and s is capacitor plate
Facing area, d is the distance between capacitor plate, and Q is electricity, and U is voltage, therefore,In actual measurement process
In, the voltage U in the detection device 40 used is fixed value voltage, and during with a Product checking, the first assembling zero
Facing area s between part conductor 10 and detection tool 30 is fixed, so, in detection process, is related apart from d and electricity Q
Amount, by the associated change for obtaining electricity Q, you can realize the measurement purpose apart from d.
The assembly relation of product parts is detected using the component assembly detection method of the technical program, compared to existing
There is the metering system of technology, measured without man-hour manually hand-held measuring scale tool, and can be quickly to batch in production line
Assembling product detected to determine product quality one by one, it is to avoid defect ware is passed to market, and relative to X-ray check
Speech, then be the health of human body of staff in production line in more safely ensureing, and the part dress of the technical program
The equipment cost of the detection device 40 and detection tool 30 applied with detection method is low, and equipment loss cost is relatively low,
Staff is simple to operate, is conducive to meeting the force of labor demand that enterprise produces product in batches.
As shown in Fig. 2 detection tool 30 includes tool flat board 31 and multiple capacitive detection sensors 32, multiple capacitance detectings
The rectangular array of sensor 32 is distributed on tool flat board 31, it is determined that between the detection Assembly part housing 20 of tool 30 and second
Relative position relation during, the relative position relation of tool flat board 31 and the second Assembly part housing 20 is uniquely set.
In detection process, it is thus necessary to determine that the relative position relation between the detection Assembly part housing 20 of tool 30 and second, i.e., no matter
When detection tool 30 is engaged to be detected to product with any one product, the Assembly part housing of tool 30 and second is detected
Relative position relation between 20 is all consistent, and fixed position relation reference is formed with this.In step S20 and step S30 mistakes
Cheng Zhong, detection device 40 is detected after the distribution of charges of each capacitive detection sensor 32, and the conversion of distribution of charges value is read as into electricity

Specifically, when the first Assembly part conductor 10 is arranged in the second Assembly part housing 20 and the first Assembly part is led
When body 10 has exposed region, during step S20 and step S30, detection tool 30 is connected conducting with detection device 40,
And the first Assembly part conductor 10 is connected conducting with detection device 40, to detect and read each capacitive detection sensor 32
Distribution of capacitance values, and will detect that obtained capacitance is compared with electric capacity reference value, now, can be straight by the comparison of capacitance
See ground and know capacitive differential, detect and read the distribution of capacitance values of each capacitive detection sensor 32 and calculated by detection device
The relative position relation of the determination between the first Assembly part conductor 10 and tool flat board 31 is can determine, so as to judge the first dress
Whether the rigging position relation replaced the spare parts between the Assembly part housing 20 of conductor 10 and second is qualified.In fact, being completed in detection
The distribution of capacitance values change on detection tool 30 is obtained afterwards, you can is calculated by detection device 40 and is obtained the first Assembly part conductor
The distance between 10 top surface and the lower surface of tool flat board 31, due to detecting the Assembly part of tool flat board 31 and second of tool 30
Relative position relation between housing 20 is uniquely determined, therefore, the top surface and the second Assembly part of the first Assembly part conductor 10
The distance of the top surface of housing 20 is also just detected and determined.Simultaneously as shown in Fig. 2 by using the capacitance detecting of detection tool 30
The detection of sensor 32 obtains distribution of capacitance values situation, determines that the first Assembly part conductor 10 is projected in detection and controlled so as to calculate
Position profile on the tool flat board 31 of tool 30, so, also just obtains the edge contour and the of the first Assembly part conductor 10
Interstitial site distance between two Assembly part housings 20.Therefore, as long as judging the top surface and of the first Assembly part conductor 10
The deviation of the distance of the top surface of two Assembly part housings 20 is in the deviation range of permission, and the first Assembly part conductor 10
Edge contour and the second Assembly part housing 20 between interstitial site distance deviation in the deviation range of permission, i.e.,
It can determine whether that the relative position of component assembly meets assembling standard, the product is qualified, otherwise the product is defect ware.
In addition, when the second Assembly part housing 20 wraps up the first Assembly part conductor 10, in step S20 and step S30
During, detection tool 30 with detection device 40 is connected conducting, to detect and read each capacitive detection sensor 32 the
The charge density Distribution Value produced under the influence of one Assembly part conductor 10, and obtained charge density Distribution Value and electric charge will be detected
Intensity reference value compares, and detects and read the charge density Distribution Value of each capacitive detection sensor 32 and set by detection
Standby 40 calculate the relative position relation that can determine the determination between the first Assembly part conductor 10 and tool flat board 31, so as to sentence
Whether disconnected rigging position relation between first Assembly part conductor 10 and the second Assembly part housing 20 is qualified.Now, first
Assembly part conductor 10 can influence corresponding capacitive detection sensor 32 in detection tool 30 to obtain distribution of charges, be obtained by detection
Obtain the distribution of charges situation of each capacitive detection sensor 32 accordingly, you can calculate the top for obtaining the first Assembly part conductor 10
Face and the distance of the top surface of the second Assembly part housing 20, and calculating determine that the first Assembly part conductor 10 is projected in detection and controlled
Position profile on the tool flat board 31 of tool 30.Therefore, as long as judging top surface and the second assembling of the first Assembly part conductor 10
The deviation of the distance of the top surface of part housing 20 in the deviation range of permission, and the first Assembly part conductor 10 edge
The deviation of interstitial site distance between profile and the second Assembly part housing 20 is in the deviation range of permission, you can judge
The relative position of component assembly meets assembling standard, and the product is qualified, and otherwise the product is defect ware.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
