DETAILED DESCRIPTION
[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 1 to 5 As shown in this embodiment, a half-piece cutting mechanism for a dicing machine includes a dicing bracket 1, a robotic arm 2, and a half-piece output module 3. The dicing bracket 1 is equipped with a lifting motor 4 and a lifting frame 5. The lifting motor 4 moves back and forth along the dicing bracket 1. The driving end of the lifting motor 4 is connected to a cam 6, which is located in the middle of the lifting frame 5. The middle of the dicing bracket 1 is equipped with a dicing laser head 7 and a dicing detection camera 8. The half-piece output module 3 includes a half-piece horizontal movement module 9, a half-piece vertical movement module 10, and a half-piece suction rod 11. The half-piece vertical movement module 10 is installed on the driving end of the half-piece horizontal movement module 9, and the half-piece suction rod 11 is installed on the driving end of the half-piece vertical movement module 10. A half-piece suction nozzle 12 is fixed on the half-piece suction rod 11.
[0024] Based on the identification of defective silicon wafers 23 and good silicon wafers 23, the robotic arm 2 picks up the qualified whole silicon wafer 23 and places it onto the dicing support 1, which is supported by the lifting frame 5. As the lifting frame 5 moves back and forth along the dicing support 1, when the whole silicon wafer 23 approaches the dicing laser head 7, the lifting motor 4 controls the cam 6 to rotate, so that the lifting frame 5 is briefly lifted up. The whole silicon wafer 23 on the lifting frame 5 is closer to the dicing laser head 7, thus completely and accurately dividing the whole silicon wafer 23 from the middle. After the dicing inspection camera 8 detects that the cutting is completed, the half wafer horizontal movement module 9 and the half wafer vertical movement module 10 on the half wafer output module 3 control the half wafer suction rod 11 to adsorb the two halves and move them to the rear.

The dicing front and rear module 14 controls the lifting frame 5 to move back and forth. When the lifting motor 4 controls the lifting frame 5 to rise through the cam 6, the upper end of the lifting frame 5 is higher than the movable groove 15 on the dicing bracket 1. The lifting frame 5 can move along the movable groove 15, driving the silicon wafer 23 to perform laser cutting.
[0027] The upper end of the lifting frame 5 is provided with several adsorption holes, which firmly adsorb and fix the silicon wafer 23 to prevent displacement and accurately perform laser cutting.
[0028] One side of the wafer support 1 is provided with a transfer support 16, and the transfer support 16 is provided with adsorption cross bars 17, and there is a gap between two adjacent adsorption cross bars 17, and the half-piece output module 3 places the cut double half-pieces on the adsorption cross bars 17 for fixation, and then the subsequent stringer inserts the rails into the gap between the adsorption cross bars 17, and then lifts the double half-pieces to take them away.
[0029] One side of the manipulator 2 is provided with a separator paper supplement box 18 and a defective placement box 19, and when the front end detects whether the whole silicon wafer 23 meets the requirements, the defective silicon wafer 23 will be placed in the defective placement box 19, and the defective silicon wafer 23 is placed in an interval mode of one layer of separator paper and one layer of silicon wafer 23, and the separator paper is taken out from the separator paper supplement box 18 and placed in the defective placement box 19, so as to separate and protect each layer of silicon wafer 23.
