Abstract
Description
Technical Field
[0001] This utility model relates to the field of wafer positioning and sorting technology, specifically to a wafer positioning and sorting device with a frame. Background Technology
[0002] The development of wafer positioning and sorting equipment can be traced back to the early days of the semiconductor manufacturing industry. With advancements in integrated circuit technology, the demand gradually shifted from simple positioning systems to more precise automated equipment. As manufacturing technologies progressed, especially microelectronics and automation, wafer positioning equipment increasingly adopted more advanced materials and algorithms to improve processing speed and accuracy.
[0003] A search revealed that in the prior art, Chinese Patent Publication No. CN210866145U, authorized on June 26, 2020, discloses a wafer positioning mechanism, including a clamping cylinder and protective grippers. The clamping cylinder includes a cylinder body and two gripper heads slidably mounted on the cylinder body. The protective grippers include two clamping components, each fixed to one gripper head. Each clamping component has a coarse positioning clamping surface and a fine positioning clamping surface, which are connected. After coarse positioning on the coarse positioning clamping surface of the two clamping components, the wafer slides to the fine positioning clamping surface for fine positioning. During the entire positioning process, only the wafer side edge contacts the coarse and fine positioning clamping surfaces, while the photolithographic surface does not contact, thus preventing contamination.
[0004] However, the device still has the following drawbacks: although it can clamp wafer pairs and hold different wafers, it cannot record the size of the wafers and cannot wrap the wafers, which will lead to damage to the wafers in subsequent processes, causing unnecessary trouble and economic losses.

The third electric push rod 705 is mainly used to drive the gripper 706 to hold the materials. The gripper 706 is mainly used for holding.
[0033] Specifically, a conveyor belt 8 is provided below one side of the gripper mechanism 7, a support column 9 is provided at the bottom of one side of the conveyor belt 8, the other side of the conveyor belt 8 is installed on the top of the isolation plate 6, a baffle 10 is provided on one side of the conveyor belt 8, a wafer clip pad 11 is provided on the conveyor belt 8, a first observation window 12 is provided on one side wall of the first protective box 1, a second observation window 13 is provided on one side of the second protective box 2, the support column 9 is mainly used to support the conveyor belt 8 to prevent bending and breakage during operation, and the isolation cover baffle 10 is mainly used to prevent the wafer clip pad 11 from falling off.
[0034] The working principle and usage process of this utility model are as follows: The conveyor belt 8 is started, and the wafer clip pad 11 is transported to the baffle 10 via the transmission belt. Then, the third motor 701 is started, and the third moving block 703 moves on the outer wall of the second threaded rod 702. When the third moving block 703 moves above the conveyor belt 8, the third electric push rod 705 is started. At this time, the gripper 706 can clamp the wafer clip pad 11. After clamping, the third motor 701 reverses, causing the third moving block 703 to move closer to the pressing mechanism 5. When the wafer clip pad 11 moves to the top of the through block 504, the gripper 706 opens, and the wafer clip pad 11 falls into the push frame 503 through the through block 504.
[0035] The user places the wafer into the top inner side of the second moving block 512 through the first observation window 12 of the connecting bracket, starts the second motor 507, and the lifting rod 508 rotates. The lifting rod 508 is fixedly connected to the rotating block 509. The lifting rod 508 drives the rotating block 509 to rotate, and then the connecting rod 510 moves on the inner wall of the rotating groove opened in the rotating block 509. The top of the second protective shell 501 is fixedly connected to the bottom of the second moving block 512. The second moving block 512 is installed on the top of the fixing post 511. Subsequently, the connecting rod 510 moves in the moving groove opened in the fixing post 511. The connecting rod 510 drives the second moving block 512 to move on the top of the fixing post 511, which can realize the fixed clamping of the wafer. The top surface of the wafer 11 is equipped with a scale 513. After the wafer is fixed, the user can observe and record the wafer size by using the scale. Then, the lifting rod 508 can be raised and lowered under the drive of the second motor 507. When it reaches a certain height, the lifting rod 508 stops rising, and the second electric push rod 505 is activated. The output end of the second electric push rod 505 passes through one side wall of the push frame 503 and pushes the wafer locking pad 11. The wafer locking pad 11 wraps around the wafer, so that the wafer will not be damaged in subsequent processes. Then, the first motor 401 is activated. The output end of the first motor 401 is connected to the lifting column 402. The outer wall of the lifting column 402 is provided with a spiral lifting mechanism. The spiral lifting groove has a limiting block 403 on one outer wall of the lifting column 402, and a limiting column 404 connected to the inner wall of the spiral lifting groove. The limiting block 403 is fixedly connected to the limiting column 404 and to the inner wall of the first protective box 1. The fixed connection between the limiting block 403 and the first protective box 1 prevents the rotating mechanism 4 from shaking during operation. The other side of the lifting column 402 is fixedly connected to the first fixed block 405. The rotation of the lifting column 402 drives the first fixed block 405 to rotate. The outer wall of the first fixed block 405 has a circular array of several sets of first electric push rods 406. The output end of the first electric push rod 406 is fixedly connected to the support clamp 407, and the first electric push rod 406 can extend and retract. The support clamp 407 extends to the outer wall of the lifting rod 508, lifting the wafer. Then, the first electric push rod 406 retracts, and the lifting column 402 rises and rotates to transport the packaged wafer into the storage box 305. When the storage box 305 is full, the servo motor 301 is activated, and the first moving block 303 slides on the outer wall of the first threaded rod 302. The storage box 305 is mounted on the top of the first moving block 303, which can transport the storage box 305 out of the first protective box 1. The user then replaces the storage box 305, and the servo motor 301 reverses, driving the first moving block 303 to drag the storage box 305 into the first protective box 1. This process is repeated.
