[0042] In the present invention, both the first linear module 302 and the second linear module 604 use a screw-nut mechanism to transmit power.

[0043] The specific working process of the present invention is as follows:

[0044] like Figure 1 As shown, the upper belt conveyor 8 starts to send an upper feeding basket 7 on its belt into the basket in and out mechanism 5, as shown in FIG. Figure 6 , Figure 7 As shown, the fourth servo motor 501 in the basket entry and exit mechanism 5 is started and drives the third belt transmission mechanism and the fourth transmission shaft 507 to rotate. Since the first pulley 509 is installed on the fourth transmission shaft 507, the first pulley 509 rotates and drives the fourth conveyor belt 508 and the second pulley 513 to rotate, and the upper feeding flower basket 7 is received through the fourth conveyor belt 508.

[0045] After the upper feeding basket 7 receives the film, the cylinder 606 starts and drives the pressing plate 608 to descend to press the upper feeding basket 7 tightly to prevent it from shaking left and right when taking the film. Figure 1 , Figure 4 , Figure 5 As shown, the film taking mechanism 4 is started, the rodless cylinder 416 is started and drives the first moving plate 420 and the slide 419 to move along the slide rail 418 through the piston 417, thereby driving the material taking tongue plate 410 to extend into the upper feeding basket 7, and the third conveyor belt 411 contacts the lower surface of the silicon wafer during the process of the material taking tongue plate 410 extending into the upper feeding basket 7, and the third servo motor 401 of the film taking mechanism 4 is started and drives the second driving wheel 409 to rotate through the second belt transmission mechanism, and the rotation of the second driving wheel 409 drives the third conveyor belt 411 to rotate, thereby taking the silicon wafer from the upper feeding basket 7 to the third conveyor belt 411, completing the transfer of the silicon wafer, and then the material taking tongue plate 410 is reset and the silicon wafer is fed to the first conveyor belt 207 in the silicon wafer conveying mechanism 2 through the third conveyor belt 411, and the first servo motor 201 and the first belt transmission mechanism rotate the first transmission shaft 205 and the first driving wheel 206 and drive the first conveyor belt 207 to rotate, thereby realizing the conveying of the silicon wafer to the next process for screen printing. After the silicon wafer is removed, Figure 6 , Figure 7As shown, the fifth servo motor 601 drives the second load fixing plate 603 and the second movable plate 602 to descend one station through the second linear module 604, so that when the material taking tongue plate 410 extends into the upper feeding basket 7 again, its third conveyor belt 411 can be located on the lower surface of the next silicon wafer.

[0046] After all the silicon wafers in the upper feeding basket 7 are sent out, the basket lifting mechanism 6 drives the basket entry and exit mechanism 5 and the upper feeding basket 7 to descend to the same plane as the lower belt conveyor 10, and the basket entry and exit mechanism 5 is started to send the empty upper feeding basket 7 into the lower belt conveyor 10.

[0047] In order to improve work efficiency and realize continuous feeding, and at the same time avoid that there is no material to supply to the rear equipment when there is no pre-stored material in the early stage of changing the flower basket, the second servo motor 301 drives the first linear module 302 to drive the first load fixing plate 304 and the first pre-stored material side plate 305 to move, so that the silicon wafers on the third conveyor belt 411 in the film-taking mechanism 4 are just sent into the silicon wafer pre-storage slot 308 in the adjacent first pre-storage material side plate 305 and the second pre-storage material side plate 307. After the silicon wafer pre-storage slot 308 is full, the first linear module 302 continues to drive the first load fixing plate 304 to rise and fall, and then the third conveyor belt 411 in the film-taking mechanism 4 continues to send out the pre-stored silicon wafers one by one, and the rear end continues to take the wafers continuously, thereby realizing continuous and stable wafer feeding.

[0048] The invention has a simple structure and is easy to use. The invention can realize automatic taking out and automatic conveying of silicon wafers from a feeding basket, has a high degree of automation, saves time and effort, and not only reduces the labor intensity of workers, but also reduces the human resource investment of enterprises. The setting of the pre-storage station can realize continuous feeding and avoid downtime affecting work efficiency.
