3) use and automatically to sweep target drone the guiding film is carried out the punching operation, form four die-cut pilot holes of boring pin pilot hole, then by the film perforating device, take two die-cut pilot holes as positioning datum, the guiding film is carried out drilling operation, form two boring pin pilot holes;
4) by following flow process the guiding film is carried out bore operation:
A, use fixedly two pieces of paper backing plate of masking tape at the drilling machine board, two pieces of paper backing plate consistency from top to bottom piles up;
B, usefulness drill bit bore two pin holes at the upper paper backing plate;
D, the two pieces of paper backing plate is taken off, and have the Paper baseplate of pin hole to squeeze into two pins on the upper strata, then this Paper baseplate is fixed in the hole slot of drilling machine board;
In e, guiding film are inserted in respectively two boring pin pilot holes on the pin on the Paper baseplate by correct direction, and compacting; Using masking tape will guide two limits that film do not hole the pin pilot hole is fixed;
F, the guiding film is carried out bore operation, hole and it is taken off after complete;
6) will guide two clamp locating pins that two of film boring pin pilot holes are inserted in respectively ready clamp for electrical measurement nails on;
7) carry out the grafting of electrical measurement testing needle according to the electrical measurement testing needle plug-in position indicating graphic that indicates on the guiding film;
8) the electrical measurement testing needle peg graft complete after, take off the guiding film, clamp for electrical measurement can carry out the operations such as follow-up wiring.
Compare with prior art, advantage of the present invention is apparent specific as follows:
1, clamp for electrical measurement uses position and the order that guiding film indication testing needle is pegged graft, and has solved the problem that traditional inserting mode position deviation is large and order is chaotic.
2, the guiding film uses die-cut pilot hole to position, and uses special-purpose film perforating device the die-cut of pilot hole of holing, and has fully guaranteed the positional precision of boring pilot hole.
3, at the guiding film that play the guiding role the boring pilot hole is set, the pilot hole precision reaches ± 0.025mm, the guiding film adds man-hour in mechanical drill, use two boring pilot holes to carry out the pin location, guaranteed the bore position precision of electroprobe pilot hole, thereby guaranteed the grafting precision of testing needle and the accuracy of sequence of positions, significantly improved make efficiency and the success ratio of test fixture.
