In conjunction with referring to figure 1 and figure 2, component assembly detection method of the invention for part conductor and insulation shell it
Between rigging position relationship detection, especially when insulation shell to part conductor formed package assembling form rigging position close
System's detection.In an embodiment of the present invention, the second Assembly part shell 20 is insulator.
In the component assembly detection method of the technical program, comprising the following steps:
The S10: the first Assembly part of step conductor 10 is located in the second Assembly part shell 20, and determine detection jig 30 with
Relative positional relationship between second Assembly part shell 20；
Step S20: when the first Assembly part conductor 10 and the second Assembly part shell 20 are standard assembly status, calibration

Whether the rigging position relationship between part shell 20 is qualified.
According to capacitor calculation formula:Wherein ε is constant, and k is electrostatic force constant, and s is capacitor plate
Positive area, d are the distance between capacitor plate, and Q is electricity, and U is voltage, therefore,In actual measurement mistake
Cheng Zhong, the voltage U in detection device 40 used are fixed value voltage, and during with a product testing, the first assembly
Positive area s between part conductor 10 and detection jig 30 is fixed, in this way, in the detection process, distance d and electricity Q is phase
The measurement purpose of distance d can be realized by obtaining the associated change of electricity Q in Guan Liang.
The assembly relation of product parts is detected using the component assembly detection method of the technical program, compared to existing
There is the measurement method of technology, measured without man-hour manually hand-held measuring scale tool, and can be quickly to batch in production line
Assembly product detected one by one to determine product quality, avoid defect ware from being passed to market, and relative to X-ray check and
Speech is then the health of human body of staff in production line in more safely guaranteeing, and the part of the technical program fills
Low with the detection equipment cost of jig 30 with detection device 40 applied by detection method, equipment loss cost is relatively low,
Staff is easy to operate, is conducive to the force of labor demand for meeting enterprise's batch production product.
As shown in Fig. 2, detection jig 30 includes jig plate 31 and multiple capacitive detection sensors 32, multiple capacitance detectings
32 rectangular array of sensor is distributed on jig plate 31, is being determined between detection jig 30 and the second Assembly part shell 20
Relative positional relationship during, jig plate 31 and the relative positional relationship of the second Assembly part shell 20 are uniquely set.
In the detection process, it is thus necessary to determine that the relative positional relationship between detection jig 30 and the second Assembly part shell 20, i.e., no matter
When detection jig 30 is matched with any one product to detect to product, jig 30 and the second Assembly part shell are detected
Relative positional relationship between 20 is all consistent, so as to form fixed positional relationship reference.In step S20 and step S30 mistake
The conversion of distribution of charges value after detection device 40 detects the distribution of charges of each capacitive detection sensor 32, is read as electricity by Cheng Zhong
Capacitance is compared with capacitor reference value, or directly reads charge density value compared with charge density reference value.
Specifically, when the first Assembly part conductor 10 is arranged in the second Assembly part shell 20 and the first Assembly part is led
When body 10 has exposed region, during step S20 and step S30, it will test jig 30 with detection device 40 and connect conducting,
And the first Assembly part conductor 10 is connect conducting with detection device 40, to detect and read each capacitive detection sensor 32
Distribution of capacitance values, and the capacitance that will test is compared with capacitor reference value, at this point, can be straight by the comparison of capacitance
It sees ground and knows capacitive differential, detect and read the distribution of capacitance values of each capacitive detection sensor 32 and calculated by detection device
It can determine the relative positional relationship of the determination between the first Assembly part conductor 10 and jig plate 31, to judge the first dress
Whether the rigging position relationship to replace the spare parts between conductor 10 and the second Assembly part shell 20 is qualified.In fact, being completed in detection
The distribution of capacitance values variation on detection jig 30 is obtained afterwards, can be calculated by detection device 40 and be obtained the first Assembly part conductor
The distance between 10 top surface and 31 lower surface of jig plate, due to detecting the jig plate 31 and the second Assembly part of jig 30
Relative positional relationship between shell 20 uniquely determines, therefore, the top surface of the first Assembly part conductor 10 and the second Assembly part
The distance of the top surface of shell 20 is also just detected and has determined.Simultaneously as shown in Fig. 2, passing through the capacitance detecting using detection jig 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 controls so as to calculate
Position profile on the jig plate 31 of tool 30, in this way, also just obtaining the edge contour and the of the first Assembly part conductor 10
Interstitial site distance between two Assembly part shells 20.Therefore, as long as judging the top surface of the first Assembly part conductor 10 and the
The deviation of the distance of the top surface of two Assembly part shells 20 is in the deviation range of permission and the first Assembly part conductor 10
Edge contour and the second Assembly part shell 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 assembly standard, the product is qualified, and otherwise the product is defect ware.
In addition, when the second Assembly part shell 20 wraps up the first Assembly part conductor 10, in step S20 and step S30
In the process, it will test jig 30 and connect conducting with detection device 40, to detect and read each capacitive detection sensor 32
The charge density Distribution Value generated under the influence of one Assembly part conductor 10, and the charge density Distribution Value and charge that will test
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 positional relationship that can determine the determination between the first Assembly part conductor 10 and jig plate 31, to sentence
Whether the rigging position relationship between disconnected first Assembly part conductor 10 and the second Assembly part shell 20 is qualified.At this point, first
Assembly part conductor 10 will affect corresponding capacitive detection sensor 32 in detection jig 30 and obtain distribution of charges, be obtained by detection
The distribution of charges situation for obtaining each capacitive detection sensor 32 accordingly can calculate the top for obtaining the first Assembly part conductor 10
Face is at a distance from the top surface of the second Assembly part shell 20, and calculates and determine that the first Assembly part conductor 10 is projected in detection and controls
Position profile on the jig plate 31 of tool 30.Therefore, as long as judging top surface and the second assembly of the first Assembly part conductor 10
The deviation of the distance of the top surface of part shell 20 is in the deviation range of permission and the edge of the first Assembly part conductor 10
The deviation of interstitial site distance between profile and the second Assembly part shell 20 can determine whether in the deviation range of permission
The relative position of component assembly meets assembly 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 in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
