[0074] In some embodiments, referring to Figure 1 and Figure 8 , the wafer feeding assembly 200 comprises a vibrating disk 210, a conveying track 220, a suction nozzle assembly 230, a suction nozzle driving assembly 240 and a feeding detection assembly 250. The conveying track 220 is connected to the vibrating disk 210 at one end, and the other end of the conveying track 220 is a wafer feeding position. The suction nozzle assembly 230 is located above the conveying track 220, and is used to suck the wafer at the wafer feeding position and release it near the placement seat 120 of the wafer feeding assembly 200. The suction nozzle driving assembly 240 is connected to the suction nozzle assembly 230, and is used to drive the suction nozzle assembly 230 to move between the wafer feeding position and the placement seat 120 near the wafer feeding assembly 200. The feeding detection assembly 250 is used to detect whether there is a wafer at the wafer feeding position.

[0075] The vibrating disk 210 vibrates to discharge the wafer, and the wafer is conveyed along the conveying track 220 to the wafer feeding position. The feeding detection assembly 250 detects that there is a wafer at the wafer feeding position. The suction nozzle driving assembly 240 drives the suction nozzle assembly 230 to move to the wafer feeding position. The suction nozzle assembly 230 sucks the wafer at the wafer feeding position. The suction nozzle driving assembly 240 drives the suction nozzle assembly 230 to move to the wafer feeding position. The suction nozzle assembly 230 releases the wafer at the wafer feeding position, and the wafer feeding is completed. The feeding detection assembly 250 detects that there is no wafer at the wafer feeding position. The vibrating disk 210 vibrates to discharge the wafer. The feeding detection assembly 250 can detect whether there is a wafer at the wafer feeding position. When there is a wafer at the wafer feeding position, the suction nozzle driving assembly 240 and the suction nozzle assembly 230 are controlled to work. When there is no wafer at the wafer feeding position, the vibrating disk 210 is controlled to work. This can avoid the suction nozzle assembly 230 working empty, avoid the wafer stacking at the wafer feeding position, and ensure the normal operation of the wafer feeding and the subsequent processes.

[0076] In some embodiments, referring to Figure 1 , Figure 8 , Figure 9 , Figure 10 and Figure 11 , the conveying track 220 comprises a track bottom plate 221, a track cover plate 222 and a feeding seat 223. The track bottom plate 221 is provided with a guide groove 2211, and the track cover plate 222 covers the guide groove 2211. The feeding seat 223 is arranged at the end of the track bottom plate 221 away from the vibrating disk 210. A notch groove 2231 is arranged above the feeding seat 223 and close to one side of the track bottom plate 221. The wafer feeding position is located at the notch groove 2231, and the guide groove 2211 is communicated with the notch groove 2231. The vibrating disk 210 vibrates to discharge the wafer, and the wafer can be conveyed along the guide groove 2211 to the notch groove 2231.

[0077] The notch groove 2231 comprises an arc-shaped inner wall, which is the inner wall of the side of the notch groove 2231 away from the track bottom plate 221, and is used to limit the position of the susceptor. When the susceptor slides into the notch groove 2231 along the guide groove 2211, the arc-shaped inner wall abuts against the outer circle of the susceptor. The arc-shaped inner wall can limit the position of the susceptor, so as to ensure that the susceptor is located at the specified position, and facilitate the suction of the suction nozzle assembly 230 to the susceptor located in the notch groove 2231.

[0078] In some embodiments, referring to Figure 1 , Figure 8 , Figure 11 and Figure 12 , the bottom wall of the notch groove 2231 is provided with a second through hole 2232, which comprises a positioning portion 2233 and a detection portion 2234 connected in communication. The positioning portion 2233 is located at the middle of the bottom wall of the notch groove 2231, and the detection portion 2234 is arranged close to the arc-shaped inner wall. When there is a susceptor in the notch groove 2231, the positioning portion 2233 is connected to the inner hole of the susceptor, and the detection portion 2234 is covered by the susceptor. The material inlet detection assembly 250 comprises a first material inlet sensor 251, which is arranged below the second through hole 2232 and has an axial direction penetrating through the detection portion 2234.

[0079] The second through hole 2232 is arranged on the bottom wall of the notch groove 2231, and the bottom wall of the notch groove 2231 around the second through hole 2232 can support the susceptor. The detection portion 2234 of the second through hole 2232 facilitates the first material inlet sensor 251 to detect whether there is a susceptor in the notch groove 2231. When there is no susceptor in the notch groove 2231, the transmission signal of the first material inlet sensor 251 penetrates through the detection portion 2234, and the first material inlet sensor 251 feeds back that there is no susceptor in the notch groove 2231. When the susceptor slides into the notch groove 2231 along the guide groove 2211, the transmission signal of the first material inlet sensor 251 is blocked by the susceptor on the detection portion 2234, and the first material inlet sensor 251 feeds back that there is a susceptor in the notch groove 2231.

[0080] In some embodiments, referring to Figure 1 , Figure 8 , Figure 11 and Figure 13The suction nozzle assembly 230 comprises a suction nozzle fixing frame 231, a suction nozzle connecting rod 232 and a suction nozzle head 233.

The plurality of suction holes 2332 are communicated to the inside of the suction nozzle connecting rod 232.

[0081] The suction nozzle driving assembly 240 drives the suction nozzle fixing frame 231 to move close to the discharge seat 223. The suction nozzle connecting rod 232 and the suction nozzle head 233 are driven to move close to the discharge seat 223. The suction nozzle head 233 abuts against the wafer. The second positioning protrusion 2331 passes through the inner hole of the wafer and extends into the positioning part 2233 of the second through hole 2232. The suction nozzle connecting rod 232 is connected to the air suction device. Negative pressure is generated at the suction holes 2332, so that the wafer is adsorbed on the suction nozzle head 233. The suction nozzle driving assembly 240 drives the suction nozzle fixing frame 231, the suction nozzle connecting rod 232 and the suction nozzle head 233 to move from the wafer discharge position to the wafer feeding position. The air suction device stops working. The wafer falls from the suction nozzle head 233 to the wafer feeding position.

When the wafer needs to be transported to the wafer feeding position, the locking cylinder 261 pushes the locking baffle 262 to move away from above the notch groove 2231, so that the suction nozzle assembly 230 can suck the wafer in the notch groove 2231. When there is no wafer in the notch groove 2231, the emission signal of the first feeding sensor 251 passes through the detection portion 2234 and the first detection groove 2621, and the first feeding sensor 251 feeds back that no wafer is detected in the notch groove 2231. The first detection groove 2621 can be arranged to avoid that the locking baffle 262 blocks the emission signal of the first feeding sensor 251 when there is no wafer in the notch groove 2231, so as to avoid misjudgment and ensure the detection accuracy of the first feeding sensor 251.
