Thirdly, driving the air cylinder (23) to work, wherein the output end of the air cylinder extends out to drive the mounting claw (36) to rotate away from the fixed claw (33), so that the fixed claw (33) and the mounting claw (36) tension the clamp spring workpiece (6), and the opening angle of the clamp spring workpiece (6) is increased;
fourthly, the lifting device works to drive the installation detection device to ascend, and the slotted hole of the clamp spring workpiece (6) to be installed is positioned under the clamp spring workpiece (6);
fifthly, the lifting device drives the installation detection device to descend until the clamp spring workpiece (6) is clamped into the slotted hole, the air cylinder (23) is driven to work, the output end of the air cylinder retracts, the installation claw (36) is driven to be close to the fixed claw (33) to rotate, the fixed claw (33) and the installation claw (36) are separated from being in contact with the clamp spring workpiece (6), and installation action is finished;
sixthly, when the displacement detection structure (4) detects that the output end of the driving air cylinder (23) extends, retracts and resets, the correlation sensor (56) works to obtain the final correlation signal delta at the momenttAnd will be0And deltatAnd (3) carrying out comparison:
if deltat-δ0＜δminIf so, the clamp spring workpiece (6) completely falls off and cannot be successfully installed;
if deltamin≤δt-δ0≤δmaxIf so, successfully installing the clamp spring workpiece (6) in place;
if, deltat-δ0＞δmaxThe clamp spring workpiece (6) is clamped at the slotted hole but is not installed in place;
wherein, deltaminAnd deltamaxThe set in-place limit small deviation and the set in-place limit large deviation.
