[0002] Semiconductor process testing encompasses numerous items, a wide range of content, and diverse methods, which can be roughly divided into two categories. The first category involves testing semiconductor wafers before, during, or after each process step. This includes testing semi-finished or finished semiconductor devices and integrated circuits. Semiconductor testing includes geometric dimensions and surface topography, component structure analysis, electrical properties, and assembly and packaging process testing.

[0003] Existing semiconductor processing generally uses detection equipment and conveying equipment to transport the semiconductor to the bottom of the detection equipment through the conveying equipment and then the detection equipment detects the semiconductor. In order to ensure the accuracy of the semiconductor detection results, it is generally necessary to detect both sides of the semiconductor. However, the existing conveying equipment cannot flip the semiconductor during the transportation process, so auxiliary manpower is required to flip the semiconductor so that the detection equipment can detect the other side of the semiconductor. In addition, during the transportation process, the semiconductor is moved from the loading equipment to the transmission equipment and is easily positionally offset after being flipped, making it impossible for the detection equipment to accurately obtain semiconductor information. Manual adjustment of the semiconductor position is required, which easily leads to low semiconductor detection efficiency. Summary of the Invention

[0020] During operation, the semiconductor is transferred to the upper transmission member 4 in the present invention (the upper transmission member 4 is moved away from the intermediate connecting plate 15 and the movable plate 9 is rotated, so that the semiconductor adsorbed by the suction cup 11 on the rotating plate 9 is moved to the top of the upper transmission member 4, and then the semiconductor is placed on the upper surface of the upper transmission member 4 by the cylinder 10), and the semiconductor moves toward the intermediate connecting plate 15 along with the upper transmission member 4. During the movement, the adjustment device on the upper transmission member 4 adjusts the position of the semiconductor (the transmission rod 29 drives the upper bevel gear 30, the upper bevel gear 30 drives the lower bevel gear 31 meshed with it, and the lower bevel gear 31 drives a group of main positioning shafts 21, and the positioning shafts of the adjacent main positioning shafts 21 rotate relative to each other through the transmission gear 22, so that the semiconductor is toggled between the toggle members 26, so that the semiconductor can be moved to the position of the symmetrically arranged toggle members 26, thereby passing through the toggle members 26, and the main positioning shaft 21 limit gear 24 dynamic chain can drive multiple groups of toggle members 26 to rotate relative to each other, which can realize the synchronous adjustment of the positions of multiple groups of semiconductors, improve the adjustment efficiency, and avoid the trouble of manual adjustment), so that the semiconductor can be accurately parallel The semiconductor moves to the bottom of the detection device 3, and the detection device 3 on the upper transmission member 4 detects one side of the semiconductor, and then the semiconductor falls into the flipping rod 19. Before falling, the corresponding cylinder 10 on the rotating plate 9 set on the upper transmission member 4 near the middle connecting plate 15 absorbs the powder of the semiconductor with incorrect detection, and the rotating plate 9 rotates to transfer the problematic semiconductor to the recycling transmission device). The semiconductor is flipped by the flipping rod 19 and falls onto the lower transmission member 5. After the position is adjusted by the adjustment device, the semiconductor moves to the bottom of the detection device 3 with the lower transmission member 5, so that the detection device 3 detects the other side of the semiconductor (after the detection device 3 on the lower transmission member 5 detects the semiconductor, when the semiconductor passes under the rotating plate 9 with the lower transmission member 5, the cylinder 10 cooperates to absorb the semiconductor with incorrect inspection and move it up again, and then rotates it to the recycling production line through the rotating plate 9), avoiding the trouble of manually flipping the semiconductor and the trouble of manually assisting in adjusting the position of the semiconductor, so that the double-sided detection of the semiconductor can be carried out fully automatically and efficiently.

[0021] In the present invention, the semiconductor is transferred to the upper transmission member 4. As the upper transmission member 4 moves toward the intermediate connecting plate 15, the adjusting device on the upper transmission member 4 adjusts the position of the semiconductor during the movement, so that the semiconductor can be accurately moved in parallel to the bottom of the detection device 3. The detection device 3 on the upper transmission member 4 detects one side of the semiconductor, and then the semiconductor falls onto the flipping rod 19. The flipping rod 19 flips the semiconductor and then falls onto the lower transmission member 5. After the position is adjusted by the adjusting device, the semiconductor moves with the lower transmission member 5 to the bottom of the detection device 3, so that the detection device 3 detects the other side of the semiconductor, avoiding the trouble of manually flipping the semiconductor and the trouble of manually assisting in adjusting the position of the semiconductor, so that the double-sided detection of the semiconductor can be carried out fully automatically and efficiently.

[0022] As a further solution of the present invention, the adjustment component includes a positioning frame 20, which is fixedly installed above the upper transmission member 4 and the lower transmission member 5 and is arranged on the left side of the detection frame 2. Multiple groups of main positioning shafts 21 are rotatably installed on the positioning frame 20, and auxiliary positioning shafts 23 are rotatably installed on one side of the positioning frame 20 corresponding to the main positioning shaft 21. Transmission gears 22 are fixedly installed on the main positioning shaft 21 and the auxiliary positioning shaft 23. The transmission gears 22 on adjacent main positioning shafts 21 and auxiliary positioning shafts 23 are meshed with each other. The lower ends of the main positioning shaft 21 and the auxiliary positioning shaft 23 are fixedly installed with toggle members 26. The toggle members 26 are symmetrically arranged and the opposite surfaces are provided with inclined extrusion surfaces. The main positioning shaft 21 is fixedly installed with a limiting gear 24, and the outer outer surface of the limiting gear 24 is connected to a transmission chain 25.

[0023] During operation, the present invention uses the transmission gear 22 to make the adjacent main positioning shafts 21 and auxiliary positioning shafts 23 rotate relative to each other (the transmission rod 29 rotates to drive the upper bevel gear 30 to rotate, the upper bevel gear 30 rotates to drive the lower bevel gear 31 meshing with it to rotate, and the lower bevel gear 31 rotates to drive a group of main positioning shafts 21 to rotate), so that the toggle member 26 toggles the semiconductor toward the middle, so that the semiconductor can be moved to the midline position of the symmetrically arranged toggle members 26, thereby passing through between the toggle members 26, and the main positioning shaft 21 can drive multiple groups of toggle members 26 to rotate relative to each other at the same time through the limit gear 24 and the transmission chain 25, so as to realize the synchronous adjustment of the positions of multiple groups of semiconductors, improve the adjustment efficiency, and avoid the trouble of manual adjustment. The toggle member 26 is continuously opened and closed to continuously adjust the position of the passing semiconductor (the guide wheels of the upper transmission member 4 and the lower transmission member 5 rotate to drive the second gear 47 to rotate, and the rotation of the second gear 47 drives the upper half-width gear 45 to rotate forward through the side gear 46, and at the same time drives the lower half-width gear 44 to rotate reversely through the side transmission member 43, and the teeth 39 of the upper half-width gear 45 and the lower half-width gear 44 alternately mesh with the first gear 42, thereby driving the first gear 42 to rotate forward and reverse continuously, and the rotation of the first gear 42 drives the active rod 33 to rotate through the cooperation of the active bevel gear 41 and the driven bevel gear 40, and the active rod 33 rotates to drive the lower gear 32 to rotate, and the lower gear 32 rotates to drive the upper gear 34 to rotate, and the upper gear 34 rotates to drive the screw member 36 to rotate, and the screw member 36 rotates alternately forward and reverse and interacts with the linkage rod 35, thereby driving the linkage rod 35 to drive the sliding rod 37 to slide back and forth continuously, and the sliding rod 37 causes the teeth 39 thereon to drive the driving gear 38 to rotate (as shown in FIG. Figure 7As shown, the tooth 39 moves to the right, causing the drive gear 38 to rotate counterclockwise, and the tooth 39 moves to the left, causing the drive gear 38 to rotate clockwise). The forward and reverse rotation of the drive gear 38 drives the toggle member 26 to continuously open and close with the operation of the upper transmission member 4 and the lower transmission member 5). The opening and closing of the toggle member 26 cooperates with the conveying efficiency of the upper transmission member 4 and the lower transmission member 5 to ensure that each group of semiconductors can be quickly adjusted in position without manual assistance.

[0024] In the present invention, the adjacent main positioning shaft 21 and auxiliary positioning shaft 23 are rotated relative to each other through the transmission gear 22, so that the toggle member 26 toggles the semiconductor toward the middle, so that the semiconductor can move to the center line position of the symmetrically arranged toggle members 26, thereby passing through between the toggle members 26, and the main positioning shaft 21 can drive multiple groups of toggle members 26 to rotate relative to each other at the same time through the limit gear 24 and the transmission chain 25, which can realize the synchronous adjustment of the positions of multiple groups of semiconductors, improve the adjustment efficiency, and avoid the trouble of manual adjustment.

The rotation of the intermediate gear 18 drives the fixed shaft 16 to rotate, and the rotation of the fixed shaft 16 drives the flipping rod 19 to rotate, so that the rotation of the flipping rod 19 is coordinated with the operating speed of the upper transmission member 4 and the lower transmission member 5 so that the semiconductors thereon can fall onto the flipping rod 19 evenly and regularly, thereby avoiding the accumulation of transported semiconductors on the flipping rod 19.
