[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 5 As shown in this embodiment, a detection mechanism with dual-plate feeding and correction includes a feeding transfer section 1, a feeding guide rail 2, an output transfer section 3, an output guide rail 4, a turntable 5, a left IV detection component 6, and a right IV detection component 7. The left IV detection component 6 and the right IV detection component 7 are located on the front sides of the turntable 5, respectively. The feeding guide rail 2 and the output guide rail 4 are located on the sides of the turntable 5, respectively. The feeding transfer section 1 includes a feeding A-side transfer component 8 and a feeding B-side transfer component 8. The transfer assembly 9, the infeed A-side transfer assembly 8, and the infeed B-side transfer assembly 9 are all provided with a transfer base plate 10. The transfer base plate 10 is provided with a first transfer module 11 and a second transfer module 12. The drive end of the first transfer module 11 and the drive end of the second transfer module 12 are connected to the infeed front and rear modules 13. The drive end of the infeed front and rear modules 13 is connected to the infeed adsorption plate 14. The outfeed transfer part 3 includes an outfeed A-side transfer assembly 15 and an outfeed B-side transfer assembly 16.

[0023] The two halves of the wafer move from the infeed guide rail 2 to the end. Under the control of the first transfer module 11 and the second moving module, they are adjusted in the XYT three-axis direction to meet the alignment requirements of the detection components at the detection position. During the correction process, the infeed A-side moving component adjusts the position of one half of the wafer, and the infeed B-side moving component is responsible for the position of the other half of the wafer. After the left IV detection component 6 and the right IV detection component 7 complete the IV detection of the two halves of the wafer, the turntable 5 turns the two halves of the wafer to the outfeed guide rail 4. The outfeed A-side transfer component 15 and the outfeed B-side transfer component 16 respectively grab the two halves of the wafer and place them on the outfeed guide rail 4 for output.

[0024] Both the first transfer module 11 and the second transfer module 12 are equipped with a first correction motor 17. The drive end of the first correction motor 17 is connected to a first correction lead screw 18. A first correction nut seat 19 is threadedly connected to the first correction lead screw 18. A first correction bearing 20 is installed on the first correction nut seat 19. The upper end of the first correction bearing 20 is rotatably connected to the front and rear infeed modules 13. A first correction lower slide rail 21 is fixed on the transfer base plate 10. The first correction nut seat 19 slides on the first correction lower slide rail 21. The lower end of the first correction bearing 20 is fixed to a first correction upper slide rail 22. The upper end of the first correction nut seat 19 slides on the first correction upper slide rail 22. The first correction upper slide rail 22 and the first correction lower slide rail 21 are perpendicular to each other.

[0025] In the correction structure of the conveying section, the first correction motor 17 controls the first correction screw 18 to rotate, which drives the first correction nut seat 19 to translate. When the moving positions of the two sets of first correction nut seats 19 are not synchronized, the angle T-axis direction is adjusted. When the moving positions of the two sets of first correction nut seats 19 are synchronized, the X-axis direction is linearly adjusted. The Y-axis direction is adjusted by the front and rear modules 13 of the infeed plate.

[0026] A voice coil motor 23 is installed on the drive end of the front and rear module 13 of the board feeding assembly. The board feeding suction plate 14 is installed on the drive end of the voice coil motor 23. The voice coil motor 23 controls the lifting and lowering of the board feeding suction plate 14 on the half silicon wafer, and puts the half silicon wafer from the board feeding guide rail 2 into the turntable 5.

[0027] An infeed camera 24 is installed above the rear end of the infeed guide rail 2. The first round of correction adjustment is achieved by taking pictures with the infeed camera 24.

[0028] Both the left IV detection component 6 and the right IV detection component 7 are equipped with one X-axis detection module and two Y-axis detection modules 25. The X-axis detection module and the Y-axis detection module 25 are connected to the detection lifting seat 26. The detection lifting seat 26 has an upper detection bracket 27 and a lower detection bracket 28 that move vertically.

[0029] During the second round of correction, the X-axis detection module and the Y-axis detection module 25 control the X-axis adjustment and Y-axis adjustment of the detection lifting seat 26, respectively. The adjustment of the angle T-axis is accomplished by the asynchronous movement of the two sets of Y-axis detection modules 25. The detection upper bracket 27 and the detection lower bracket 28 move closer to the silicon wafer in the middle and perform IV detection after contacting the contact point.

[0030] Both the A-side transfer assembly 15 and the B-side transfer assembly 16 are fixed with front and rear panels for board output, and the drive ends of the front and rear panels for board output are connected to a board output adsorption plate.

[0031] The two half-wafers output from turntable 5 are picked up by the A-side transfer assembly 15 and the B-side transfer assembly 16 respectively and moved to the output guide rail 4 for removal.

[0032] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
