the lifting tray 543 is driven by the lifting tray motor 545 to continuously descend through the screw rod module 546 until the lifting tray 543 is lowered to the original position; when the tray sensor 5483 in the tray lifting assembly 54 senses that one side of the tray lifting assembly is provided with the tray 7, the tray sensor 5483 automatically sends a signal sensed by the tray sensor 5483 to the controller, the controller receives the signal from the tray sensor 5483 and then controls the side positioning cylinder 5491 and the front end positioning cylinder 5482 to start working respectively, and the side positioning push plate 549 is driven by the side positioning cylinder 5491 connected with the side positioning cylinder 549 to approach to the direction of the side positioning block 547 by taking the side positioning block 547 as a reference, so that when the side positioning push plate 549 and the side positioning block 547 are matched for use, the left direction and the right direction of the tray 7 can be limited and fixed; similarly, the front positioning push plate 5481 is driven by the front positioning cylinder 5482 connected with the front positioning push plate 5481 to approach the direction of the front positioning block 548 by taking the front positioning block 548 as a reference, so that the front positioning push plate 5481 and the front positioning block 548 can limit and fix the front direction and the rear direction of the material tray 7 when being matched for use; when the tray lifting assembly 54 moves to one side of the test fixture 2 through the tray moving belt pulley module 52 and under the drive of the tray moving motor 53, the tray lifting assembly can prepare for feeding chips; when the empty tray sensor 502 in the upper and lower tray mechanism 5 senses that the four tray storage vertical plates 58 in the tray receiving station 56 are lack of the trays 7 with chips, the empty tray sensor 502 automatically sends the sensed signals to the controller, and the controller receives the signals fed back by the empty tray sensor 502 and then controls the alarm electrically connected with the empty tray sensor to sound so as to prompt that the trays 7 filled with chips need to be stacked in the tray receiving station 56 for material preparation; because the chip feeding and discharging mechanism 4 can move forward and backward and left and right through the positioning module 3, the chip feeding and discharging mechanism 4 can be moved to the upper surface of the material disc lifting assembly 54 on one side of the test fixture 2 through the positioning module 3, when the chip lifting motor 43 drives the chip lifting gear 44 to rotate forward and backward, the two chip lifting racks 45 can respectively reversely lift under the driving of the chip lifting gear 44 which rotates forward and backward, namely, when one chip lifting rack 45 moves downward, the other lifting gear moves upward; since each chip lifting rack 45 is connected and assembled with one chip lifting slide block 46, each chip lifting slide block 46 can lift along with the lifting of the chip lifting rack 45 connected with the chip lifting slide block 46, so that the chip suction nozzle 48 can lift along with the lifting of the chip lifting slide block 46 through the suction nozzle mounting plate 47; when one of the chip suction nozzles 48 is lowered and sucks one chip from the tray 7 of the tray lifting assembly 54, the other chip suction nozzle 48 is lifted up to not suck the chip, for example, when the left or rear chip suction nozzle 48 is lowered to suck one chip, the right or front chip suction nozzle 48 is lifted up to not suck the chip, whereas when the right or front chip suction nozzle 48 is lowered to suck one chip, the left or rear chip suction nozzle 48 is lifted up to not suck the chip.
