through starting to detect jack 23 on the transfer plate, so when the transfer plate moves to the below of detecting machine 4, detect jack 23 can peg graft mutually with detection socket 22, and then make detecting machine 4 and transfer plate intercommunication, detect the chip, reach automated inspection's effect, and the design of elastic sheet 24 can cushion when detecting jack 23 and detection socket 22 peg graft, avoid the impact force too big to cause the damage to equipment.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations and modifications of the present invention will be apparent to those of ordinary skill in the art in light of the foregoing description. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present invention.
