The implementation process and principle of the scheme are described in detail as follows:
when the sucking disc mechanism 2 picks up, firstly, the base frame 1 is moved to the position above the IC chip by the operation platform, so that the sucking head 22 is vertically opposite to the IC chip, at the moment, the sliding seat 4 of the lifting driving mechanism 3 descends and displaces, the tubular main body 21 also descends and displaces in the descending process of the sliding seat 4, when the sucking head 22 abuts against the IC chip, the sliding seat 4 continues to descend, at the moment, the floating elastic piece 5 is compressed, the tubular main body 21 is in a static state relative to the IC chip, therefore, the proximity sensor 7 on the sliding seat 4 generates a large gap with the detection ring 6, and when the detection range of the proximity sensor is exceeded, the optimal adsorption position is reached.
it should be noted that the pulse signal of the elevating drive source of the elevating drive mechanism 3 is matched with the detection signal of the proximity sensor, so that the driving amount of the elevating drive source can be determined, and the initial positioning function is realized, that is, the detection signal of the proximity sensor is collected by the picking-up operation of the suction cup mechanism 2 without setting the fixed displacement amount by a program, thereby determining the appropriate driving amount of the elevating drive source.
in addition, the IC chip is picked up to the burning area from the carrying disc, the sucking disc mechanism 2 firstly picks up the IC chip on the carrying disc, therefore, the driving amount of the current lifting driving source is recorded during picking up, when the IC chip is sent to the burning area to be burned and detected, the sucking disc mechanism 2 adopts the same driving amount to carry out lifting displacement to pick up the IC chip in the burning area, when the material overlapping occurs, a detection signal of the proximity sensor and a pulse signal of the real-time lifting driving source generate a large error, and at this time, the IC chip in the burning area is judged to be in the material overlapping state.
