Bonding wire push-pull force detection machine and detection method for bonding wire push-pull force

Abstract

The invention relates to the technical field of chip welding strength detection, and discloses a welding wire push-pull force detection machine and a detection method for welding wire push-pull force, the welding wire push-pull force detection machine comprises a rack, a test bin, a clamp, a test disc, a speed reduction control mechanism and an elastic force reversing transmission mechanism, the test bin can vertically ascend and descend relative to the rack, and the clamp can horizontally move relative to the rack; the test disc and the speed reduction control mechanism are both mounted in the test bin; according to the welding wire push-pull force detection machine, through cooperation of the speed reduction control mechanism and the elastic force reversing transmission mechanism, when the test bin moves downwards, the contact plate firstly makes contact with the clamp, and the induction assembly monitors the position of the contact plate so as to reduce the descending speed of the test bin; the lever pushes the reset spring to stretch to the maximum length and then automatically shrinks, and the contact plate is pulled to move upwards to be separated from the clamp. An additional control structure is not needed, the contact plate is prevented from hindering detection, the problem that the testing head moves downwards rapidly and is prone to collision is solved, and smooth detection is guaranteed.
