The two groups of chip trays 7 are precisely positioned by the anti-bias positioning pins 703 and the anti-bias positioning grooves 704 to prevent deviation. Then, after the chip tray 7 is flipped over, the electric tray clamping claw 1308 can also remove the upper chip tray 7.

After the tray flipping mechanism 14 is started, the telescopic pneumatic guide rail 1405 can drive the electric flipping claw 1406 to move forward and clamp the two groups of chip trays 7 together. Then the lifting cylinder 1404 drives the electric flipping claw 1406 to rise along the lifting slide rail 1402, and then the flipping motor 1407 can drive the two groups of chip trays 7 to flip 180° to turn the chips over. Then the electric flipping claw 1406 puts the two groups of chip trays 7 back on the tray supporting mechanism 6, and at the same time the tray clamping mechanism 13 removes the chip tray 7 covering the top, so that the chip tray 7 supporting the chip can be moved to the bottom of the second optical detection probe 11 to detect the other side.

[0029] Working principle: When using this kind of power chip finished product detection device, the chip tray 7 can be placed on the left end of the synchronous conveyor belt 5 first, and then the chip can be placed on the chip loading tray 807 on one side of the automatic plate swinging mechanism 8. Then the equipment can be started, and the stepper motor 2 will drive one end of the synchronous conveyor belt 5 through the first pulley transmission mechanism 3 to send the chip tray 7 to the top of the tray supporting mechanism 6 at the automatic plate swinging mechanism 8, and then the upper pneumatic guide rail 602 is started to make the tray support platform 603 rise upward, and the tray support platform 603 will lift the chip tray 7 upward, so that the chip tray 7 is out of contact with the synchronous conveyor belt 5, so that the chip tray 7 stays at the automatic plate swinging mechanism 8, and the tray positioning pin 604 on the tray support platform 603 cooperates with the tray positioning groove 701 on the chip tray 7 to prevent the chip tray 7 from deflecting; Then the automatic tray swing mechanism 8 is started, and the pneumatic pick-up suction cup 806 can move in all directions through the horizontal pneumatic guide rail 801, the longitudinal pneumatic guide rail 803 and the lifting pneumatic guide rail 805, so as to move to the chip loading tray 807, and then the pneumatic pick-up suction cup 806 can pick up the chip through negative pressure and accurately place it in the chip placement groove 702 on the chip tray 7; After the chips are placed, the tray support 603 will descend and put the chip tray 7 back on the synchronous conveyor 5. Then the chip tray 7 moves backward to under the first optical detection probe 10. The tray support mechanism 6 at the first optical detection probe 10 lifts the chip tray 7 to position it. Then the first optical detection probe 10 performs optical detection on all the chips on the chip tray 7 at the same time. After the detection is completed, the chip tray 7 is conveyed to the tray support mechanism 6 between the first optical detection probe 10 and the second optical detection probe 11. The tray support mechanism 6 at this position lifts the chip tray 7 to position it. Then the support mechanism 6 The servo motor 1306 on the tray clamping mechanism 13 is started, and the linear slider 1303 is driven to move along the linear slide rail 1302 through the transmission of the third screw nut 1305, so that the electric tray clamping claw 1308 moves with the chip tray 7 to the top of the chip tray 7 supporting the chip on the tray supporting mechanism 6, and then the clamping pneumatic guide rail 1307 drives the electric tray clamping claw 1308 to descend, and buckles the chip tray 7 on the chip tray 7 supporting the chip, and the two groups of chip trays 7 are accurately positioned by the anti-bias positioning pin 703 and the anti-bias positioning groove 704 to prevent deviation; Then the tray turning mechanism 14 is started, and the telescopic pneumatic guide rail 1405 drives the electric turning clamp 1406 to move forward to clamp the two groups of chip trays 7 together, and then the lifting cylinder 1404 drives the electric turning clamp 1406 to rise along the lifting slide rail 1402, and then the turning motor 1407 can drive the two groups of chip trays 7 to turn 180 degrees to turn the chips over, and then the electric turning clamp 1406 puts the two groups of chip trays 7 back on the tray supporting mechanism 6, and at the same time the tray clamping mechanism 13 takes away the chip tray 7 covered on the top, so that the chip tray 7 supporting the chip can be moved to the bottom of the second optical detection probe 11 to detect the other side; The position and height of the first optical inspection probe 10 and the second optical inspection probe 11 can be accurately adjusted by the inspection and adjustment mechanism 9. When a problem is found in a chip on the chip tray 7 after inspection and comparison, the position and height of the first optical inspection probe 10 and the second optical inspection probe 11 can be confirmed by moving the inspection and adjustment mechanism 9. When the inspection and adjustment mechanism 9 is working, the longitudinal adjustment motor 903 can drive the longitudinal adjustment screw 905 to rotate through the second pulley transmission mechanism 904, so that the longitudinal moving frame 907 can be driven by the screw transmission to move along the longitudinal adjustment slide rail 902 to achieve the front and rear position adjustment of the first optical inspection probe 10 and the second optical inspection probe 11. The lateral adjustment motor 908 can drive the lateral adjustment screw 909 to rotate, and the lateral adjustment screw 909 can drive the lateral adjustment frame 911 to move left and right through the screw transmission, while the first optical inspection probe 10 and the second optical inspection probe 11 can be moved separately through the first height adjustment cylinder 913 and the second height adjustment cylinder 915 respectively.
