It should be emphasized that if a one-round detection method is adopted, that is, the transmission efficiency of the bidirectional driving mechanism to the air pump 10 is kept constant and is large enough, then the printed resistor wire which cannot pass through in the previous round may directly fall off due to the excessive attractive force of the air pump 10, which will certainly increase the subsequent repair difficulty.
Specifically, referring to fig. 1-9, the following detailed description is provided:
the detection plate 7 is provided with a plurality of pressure sensors which are arranged in a matrix manner, and in order to ensure the accuracy of detection and ensure the obvious comparison of pressure value data at two sides, the pressure sensors with ultra-high precision are preferably selected;
secondly, the clamping mechanism comprises a first screw rod 3 rotatably installed on the base 1, two guide rods 4 fixedly arranged on the base 1 and respectively positioned on two sides of the first screw rod 3, and a lifting plate 5 slidably arranged on the two guide rods 4;

the process is the second round of detection, if the second round of detection passes, the detection is repeated, and the pressure value data obtained by the computer are not obviously different after the detection of a plurality of rounds, so that the quality of the welding wire is qualified.
