[0021] refer to Figures 1-3As shown, a first gripping assembly 3 is installed on the first mounting platform 251. The first gripping assembly 3 includes a first motor 31, a second motor 32, and a first gripper 33. The first motor 31 is mounted on the first mounting platform 251 via a first mounting bracket 311. The second motor 32 is mounted on the output end of the first motor 31 via a second mounting bracket 321. The fixed end of the first gripper 33 is mounted on the output end of the second motor 32. The first motor 31 drives the second motor 32 to rotate 90°, and the second motor 32 drives the first gripper 33 to rotate 180°. The first gripper 33 is used to grip the wafer, thereby enabling the wafer to be converted from a horizontal state to a vertical state and adjusting the front orientation of the wafer.

The plate ring 51 is installed on the first mounting plate 231, and the two barcode readers 52 are installed on the plate ring 51 and are symmetrically arranged. When the first gripper 33 and the second gripper 4 clamp the wafer through the plate ring 51, the barcode readers 52 can automatically read the QR code information on the wafer to realize wafer material classification and tracking.

[0024] refer to Figures 3-4As shown, two limiting components 6 are installed on both the first mounting plate 231 and the second mounting plate 241. The two limiting components 6 are symmetrically arranged and located on both sides of the first vertical linear motor 25. Each limiting component 6 includes a cylinder 61, a slider 62, a mounting block 63, and a limiting rod 64. The cylinder 61 is mounted on the first mounting plate 231. One end of the slider 62 is mounted on the output shaft of the cylinder 61. A groove 611 is provided on one side of the cylinder 61, and the other end of the slider 62 is slidably mounted in the groove 611. The mounting block 63 is mounted on the slider 62. One end of the limiting rod 64 is mounted on the mounting block 63, and a guide wheel 641 is provided on the other end of the limiting rod 64. The cylinder 61 can drive the slider 62 to move, the slider 62 drives the mounting block 63 to move, and the mounting block 63 drives the limiting rod 64 to move. The guide wheel 641 on the limiting rod 64 on both sides of the first vertical linear motor 25 limits the wafer and ensures that the wafer's posture is stable during movement.

[0025] refer to Figures 1-4 As shown, a storage rack 7 is provided on one side of the base 1. The storage rack 7 is provided with multiple storage platforms 71 for placing wafers. The wafers on the storage platforms 71 face the front. A cache rack 111 is provided in the cache area 11. The cache rack 111 is provided with several placement slots for vertically placing wafers. Two worktables 121 are provided in the sorting area 12. The two worktables 121 are symmetrically arranged. The first pneumatic gripper 33 picks up the wafers on the storage platform 71 and puts them into the placement slots on the cache rack 111. The second pneumatic gripper 4 picks up the wafers in the placement slots and puts them into the worktables 121. The handling is fast.

[0026] Further explanation of this embodiment: Since two worktables 121 are provided at the sorting area 12 and the two worktables 121 are symmetrically arranged, during the process of the first gripper 33 moving the wafer on the storage platform 71 into the cache rack 111, the first motor 31 drives the second motor 32 to rotate 90°, so that the first gripper 33 is in a horizontal state. The two double-acting linear motors 22 drive the first actuator seat 221 to drive the first longitudinal linear motor 23 to move laterally. The first longitudinal linear motor 23 drives the first vertical linear motor 25 to move longitudinally. The first vertical linear motor 25 drives the first mounting platform 251 to move vertically. The first mounting platform 251 drives the first gripping component 3 to move vertically, so that the first gripper 33 approaches the wafer on the storage platform 71 and clamps it. After being gripped, the first vertical linear motor 25 drives the first mounting platform 251 to move vertically, and the first mounting platform 251 drives the first gripping component 3 to move vertically. After the first gripping component 3 is a certain distance away from the plate ring 51, the first motor 31 drives the second motor 32 to rotate 90°, so that the wafer is in a vertical state and the front of the wafer faces the storage rack 7. When it is necessary to adjust the orientation of the wafer, when the first motor 31 drives the second motor 32 to rotate, the second motor 32 drives the first pneumatic gripper 33 to rotate 180°, thereby adjusting the orientation of the wafer so that the front of the wafer faces the cache rack 111. When the wafer is in a vertical position, the cylinders 61 on both sides of the first vertical linear motor 25 drive the slider 62 to move, the slider 62 drives the mounting block 63 to move, the mounting block 63 drives the limit rod 64 to move, the limit rod 64 drives the guide wheel 641 to move, and the guide wheel 641 limits the wafer to ensure that the wafer's posture is stable during the movement. The gantry conveying mechanism 2 causes the first gripper 33 to move the wafer to the top of the buffer rack 111. The first vertical linear motor 25 drives the first mounting platform 251 to move downward, and the first mounting platform 251 drives the first gripping component 3 to move downward, causing the first gripper 33 to move the wafer downward. The wafer maintains its corresponding posture under the limit of the guide wheel 641. When passing through the plate ring 51, the barcode reader 52 on the plate ring 51 automatically reads the QR code information on the wafer. The wafer continues to move downward until it is placed in the buffer slot of the buffer rack 111. The information recorded by the barcode reader 52 can classify and track the placed wafer, thereby ensuring the subsequent gripping by the second gripper 4. The second gripper 4 is moved above the buffer rack 111 by the gantry transport mechanism 2. The second vertical linear motor 26 drives the second mounting platform 261 to move downward, and the second mounting platform 261 drives the second gripping component to move downward until the second gripper 4 picks up the wafer. The second vertical linear motor 26 then drives the second mounting platform 261 to move upward, and the second mounting platform 261 drives the second gripping component to move upward, so that the second gripper 4 picks up the wafer and moves upward. When the wafer passes the plate ring 51, the barcode reader 52 on the plate ring 51 automatically reads the QR code information on the wafer, identifies the wafer information, and confirms the orientation of the wafer face. At this time, the wafer is limited by the limiting component 6 to ensure that the wafer's posture is stable during transport. Then, the second gripper 4 places the wafer on the corresponding worktable 121 by the gantry transport mechanism 2. There is no need to adjust the orientation of the wafer face, and the wafer information can be confirmed and recorded in real time during the transport process.

[0027] It should be noted that whether the wafer has been adjusted to face forward or not, it is placed directly into the buffer slot. The two barcode readers 52 are set to ensure that the QR code on the wafer can be scanned and identified when the wafer faces forward towards the storage platform 71 or the buffer rack 111. The barcode readers 52 enable full-process material data tracking and meet the traceability requirements of intelligent manufacturing.

[0028] It should be noted that the dual worktable 121 design, along with the second motor 32, enables the wafer to rotate 180°, thereby achieving efficient wafer pick-up and drop-off.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
