The working process and principle are as follows: before measuring the capacitance value of the capacitor, firstly, the center distance of the jacks 4 is adjusted according to the pin pitch of the detection sample 14, and the adjustment process comprises the following steps: the adjusting rod 81 is manually rotated, the adjusting rod 81 drives the driven wheel to rotate through the driving wheel 83, the lead screw 85 is further driven to rotate, due to the fact that the lead screw is in threaded connection with the threaded hole 87, the corresponding adjusting block 3 is further driven to move on the rectangular groove 88 through the rectangular plate 86, the position of the pointer 10 on the graduated scale 9 is observed at the moment, and when the distance between the scale on the graduated scale 9 pointed by the pointer 10 and the pin of the detection sample 14 is equal, the adjusting rod 81 stops rotating. After the test sample 14 is inserted into the inner cavity 12 through the insertion hole 4, the following situations may occur during the insertion of the pin of the test sample 14: when the pin of the test specimen 14 is completely inserted into the inner cavity 12, after the pin of the test specimen 14 contacts the support 74, the adjustment screw 710 drives the sliding rod 71 to move downward in the sliding cavity 78 against the elastic force of the fourth spring 76, and the wing 77 moves in the wing groove 79, so as to ensure that the sliding rod 71 does not rotate, during the downward movement of the sliding rod 71, since the locking rod 66 is located in the locking groove 75, the sliding rod 77 drives the driving block 61 to move along the side groove 65 toward the lower portion of the inner cavity 12 against the pushing force of the second spring 63, and since the driving block 61 moves downward, the pulling rope 610 tends to be in a loose state, at this time, under the pulling force of the tension spring 58, the rotating column 55 rotates upward along the annular guide column 57, when the conductive tip 51 starts to clamp the pin, the conductive tip 51 compresses the first spring 53, at this time, the pressure value of the pressure sensor 54 increases with the compression of the first spring 53, when the pin is completely inserted into the cavity 12, the pressure value sensed by the pressure sensor 54 is inconvenient to maintain, when measuring the capacitance, in order to ensure that the conductive terminal 51 is in close contact with the pin and ensure the stability of the power-on, and simultaneously, the pressure of the conductive terminal 51 on the pin cannot be overlarge and damage to the pin can be caused by overlarge pressure, therefore, the pressure sensor 54 is provided with a threshold value, when the detection sample 14 is completely inserted into the cavity 12, if the threshold value sensed by the pressure sensor 54 does not exceed the pressure threshold value, the pressure of the conductive terminal 51 on the pin of the detection sample 14 is insufficient, at this time, the adjusting screw 710 is screwed to drive the sliding rod 71 to move downwards, at this time, the conductive terminal is driven by the linkage mechanism 6 to apply pressure on the pin of the detection sample 14, when the applied pressure reaches the threshold value of the pressure sensor 54, the adjusting screw 710 is, if the threshold sensed by pressure sensor 54 exceeds the pressure threshold, then adjusting screw 710 is reversed until the pressure sensed by pressure sensor 54 reaches the threshold; when the pins of the detection sample 14 are completely inserted into the inner cavity 12, the pins still cannot touch the supporting table 74, at this time, the threaded rod 72 is rotated, the threaded rod 72 drives the supporting table 74 to touch the pins, at this time, the linkage mechanism 6 still cannot move downwards, so that the clamping mechanism 5 cannot clamp and fix the pins, at this time, the detection sample 14 is taken out, the supporting table is further lifted upwards by the threaded rod 72 for a proper distance, then the detection sample 14 is inserted into the inner cavity 12 again, the clamping mechanism 5 clamps the pins, and at this time, the pressure of the pressure sensor 54 is adjusted by the adjusting screw rod 710. After the adjustment is completed, the pin of the capacitor to be measured is inserted into the inner cavity 12 through the jack 4 for measurement, after the measurement is completed, the button 14 is pressed, the electromagnet 68 is electrified to generate magnetic force, suction force is generated on the locking rod 66, the locking rod is enabled to overcome the elastic force of the third spring 67 and move towards the direction close to the electromagnet 68, when the locking rod 66 is completely separated from the locking groove 75, the driving block 61 is driven to move towards the upper part of the inner cavity 12 under the pulling force of the second spring 63, so that the conductive end head 51 releases the pin of the capacitor, at the moment, the measured capacitor is taken out after the button 13 is released, when the button 13 is released, the electromagnet 68 is de-electrified, the locking rod 66 is contacted with the surface of the sliding rod 71 under the pushing force of the third spring 67, after the capacitor is taken out, the sliding rod 71 moves upwards under the elastic force of the fourth spring 76, in the moving process, when the locking groove 75 is opposite to the, the locking bar 66 is moved into the locking groove 75 by the third spring 67, and after completion, the next capacitor is measured.
Based on the above, with the pin clamping device of the capacitance detection system of the present invention, before the capacitance value is measured, the center distance between the two jacks is adjusted by the adjusting mechanism, so that the center distance is equal to the pin distance of the capacitance, then the driving mechanism is properly adjusted according to the pin length, so that the driving mechanism can normally drive the linkage mechanism when the pin is inserted into the jack, and when the capacitance value is measured, after the capacitance is inserted into the jack, the linkage mechanism is driven by the driving mechanism to move, so as to drive the driving mechanism to be in close contact with the pin, so that the measurement power supply is connected with the capacitance, and the measurement is completed.
The invention has been described in an illustrative manner, and it is to be understood that the invention is not limited to the precise form disclosed, and that various insubstantial modifications of the inventive concepts and solutions, or their direct application to other applications without such modifications, are intended to be covered by the scope of the invention.
