[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0036] Specifically, the full basket defect detection module 200 and the full basket defect rejection module 300 are arranged at the streamline end of the silicon wafer feeding and docking belt line 100; the full basket defect rejection module 300 adopts a "U"-shaped material basket supply method with the upper layer of the defect basket output and the lower layer of the repair basket flowing in and rising and falling; the docking section flower basket transfer module 400 is used for the spatial transfer of silicon wafer flower baskets.

[0037] See also Figure 2The silicon wafer feeding docking belt line 100 includes a docking belt frame 110, a belt driving assembly 120 and a docking belt 130; a plurality of belt basket sensors 140 are set on the docking belt frame 110 on both sides of the docking belt 130.

[0038] The belt drive assembly 120 includes a docking belt drive motor, a drive sprocket, a chain, a drive roller, and a transmission roller. The number of belt basket sensors 140 is related to the maximum number of wafer baskets that the docking belt 130 can support, as well as the corresponding positions of the infeed sensor, outfeed sensor, cooling station, and inspection station.

[0039] The full basket defect detection module 200 includes a basket upper layer detection component 210 and a basket lower layer detection component 220. Figure 3 and Figure 4 The upper layer detection component 210 and the lower layer detection component 220 of the flower basket both include a defect detection camera unit 202, a detection light source 203 and a detection outer sealing plate 204 arranged on the detection frame 201, wherein the defect detection camera unit 202 and the detection light source 203 of the upper layer detection component 210 of the flower basket are arranged downward, and the defect detection camera unit 202 and the detection light source 203 of the lower layer detection component 220 are arranged upward.

[0040] In this specific example, the inspection frame 201 is constructed of a box-frame structure constructed from profiles. Multiple defect detection camera units 202 are spaced side by side in the center of the upper portion of the inspection frame 201. Multiple inspection cover plates 204 are positioned around the upper portion of the inspection frame 201, near the cameras and light sources. For the upper layer inspection assembly 210, the inspection light source 203 is positioned above the defect detection camera units 202, illuminating downward. For the lower layer inspection assembly 220, the inspection light source 203 is positioned above the defect detection camera units 202, illuminating upward.

[0041] The detection light source 203 is a strip light, and the detection outer sealing plate 204 is a mirror-finished stainless steel plate.

[0042] See also Figure 5 The full basket defect rejection module 300 includes a full basket output flow line 310, a full basket rejection lifting flow line 320, a full basket inflow flow line 330, and a full basket repair lifting flow line 340, which are arranged on a full blue defect rejection rack 350. The full basket output flow line 310 and the full basket inflow flow line 330 are arranged on the full blue defect rejection rack 350 with an interval between them. The full basket rejection lifting flow line 320 is vertically arranged at the outer end of the full basket output flow line 310, and the full basket repair lifting flow line 340 is vertically arranged at the inner end of the full basket inflow flow line 330.

[0043] The full basket output flow line 310 is arranged downstream of the docking belt line 100, and the docking section flower basket transfer module 400 transfers the full flower basket detected with fragment defects from the previous station to the full basket output flow line 310. The full basket output flow line 310 is used to transfer the full flower basket detected with fragment defects to the manual repair position at the outer end; the full basket rejection lifting flow line 320 is arranged on the full blue defect rejection rack 350 at the outer end of the full basket output flow line 310, and is used to receive the manual repair position. The repaired full basket descends to the receiving position of the full basket inflow line 330; the full basket inflow line 330 is arranged below the full basket outflow line 310 and is used to transport the repaired full basket from the outside to the inside to the repair ascending position. The full basket repair lifting line 340 is arranged vertically opposite the full basket rejection lifting line 320 and is used to raise the repaired full basket from the full basket inflow line 330 to the repair transfer station aligned with the full basket outflow line 310. The docking section basket transfer module 400 transfers the repaired full basket from the full basket repair lifting line 340 to a downstream station, such as a sorting machine. As can be seen, the supply flow line of the full baskets that have been detected as defective forms a "U"-shaped supply line.

[0044] Among them, the arrangement of the full basket output streamline 310 and the full basket inflow streamline 330 can be horizontally parallel or inclined parallel. When arranged inclined parallel, the full basket output streamline 310 and the full basket inflow streamline 330 are both arranged obliquely downward from the inner end, that is, the end where the full basket repair lifting streamline 340 is located, to the outer end, that is, the full basket removal lifting streamline 320.

[0045] See also Figure 6 and Figure 7 The full basket output streamline 310 and the full basket inflow streamline 330 both include a full basket streamline rack 301, a full basket streamline drive assembly 302, a full basket streamline blocking buffer block assembly 303 and a full basket streamline in-position sensor 304; the full basket streamline drive assembly 302 is arranged on the full basket streamline rack 301, and the full basket streamline blocking buffer block assembly 303 and the full basket streamline in-position sensor 304 are arranged on both sides of the full basket streamline rack 301 in the transportation direction; the full basket output streamline 310 and / or the full basket inflow streamline 330 also include a side guide plate 305 and a side pushing module 306 for guiding the silicon wafer flower basket.

[0046] Among them, the full basket streamline frame 301 can be supported by profiles.

Of course, other forms of transmission methods can also be used, as long as the stable transportation of the flower basket is achieved. The multiple full basket streamline blocking buffer block assemblies 303 adopt a buffer block structure driven by pneumatic, hydraulic or electric cylinder lifting and lowering. The style is not limited, as long as it plays the role of side stop and buffer limit. The full basket streamline in place sensor 304 adopts the form of a photoelectric sensor, etc., and can be arranged on one side of the full basket streamline frame 301. The two side guide plates 305 are arranged on both sides above the full basket streamline frame 301 for side guidance of the flower basket. The side pushing module 306 adopts a propulsion block structure driven horizontally by pneumatic, hydraulic or electric cylinder. In the illustrated example, the side guide plates 305 and the side pushing modules 306 are arranged at the full basket inflow streamline 330 .

[0047] Furthermore, a debris receiving box is provided below the conveying chain of the full basket flow line driving assembly 302 of the full basket output flow line 310 for receiving silicon wafer fragments or debris dropped from the flower basket.

[0048] See also Figure 8 The full basket rejection lifting streamline 320 includes a flower basket lifting chain platform 321, a lifting upper side plate 322, a lifting lower side plate 323, a material removal lifting cylinder 324 and a material removal lifting guide assembly 325; the side of the flower basket lifting chain platform 321 is supported and arranged between the two lifting upper side plates 322, and the two material removal lifting cylinders 324 are vertically arranged between the corresponding side lifting upper side plates 322 and the lifting lower side plates 323, the top of the piston rod of the upper part of the material removal lifting cylinder 324 is connected to the outer side of the top of the lifting upper side plate 322, and the outer side and bottom of the lower part of the material removal lifting cylinder 324 are connected to the inner side of the lifting lower side plate 323, and each lifting lower side plate 323 is provided with a material removal lifting guide assembly 325 on both sides of the material removal lifting cylinder 324, and the top of the material removal lifting guide assembly 325 is connected to the bottom of the lifting upper side plate 322 through a guide side support plate 326.

[0049] The basket lifting chain platform 321 utilizes a similar structure to the full basket output streamline 310, except that its transmission distance is reduced and it only accommodates one basket width. Its purpose is to receive defective full baskets from the full basket output streamline 310. Furthermore, guide and stop mechanisms, such as guide and stop plates with oblique outward openings, are installed on the sides and outer ends of the basket lifting chain platform 321. A pick-up sensor is installed on the upper lifting side plate 322.

[0050] See also Figure 9The full basket repair lifting streamline 340 includes a flower basket lifting platform 341, a lifting upper mounting plate 342, a lifting lower mounting plate 343, a repair lifting component 344 and a repair lifting guide component 345; one side of the repair lifting component 344 is fixed to the outer side of the lifting upper mounting plate 342 and the lifting lower mounting plate 343, and the drive transmission section of the repair lifting component 344 is connected to the flower basket lifting platform 341. The repair lifting guide component 345 is arranged on both sides of the repair lifting component 344 and is connected to the outer side of the lifting upper mounting plate 342 and the lifting lower mounting plate 343.

[0051] The basket lift platform 341 includes a platform flat plate, a platform rib, and a platform upright plate. The upper and lower lift mounting plates 342 and 343 can be separate or integrated, depending on installation space. The repair lift assembly 344 utilizes a linear motor, rack and pinion, or motor belt. In this example, a motor timing belt mechanism is used.

[0052] The structure of the repair lifting guide assembly 345 is the same as that of the pick material lifting guide assembly 325, and adopts the structure of guide shaft and guide sleeve. Of course, the slide rail and slider mechanism can also be adopted, as long as it plays the guiding role on both sides.

[0053] Furthermore, a repair lifting limit member 346 is set on the top end side of the flower basket lifting platform 341, and a repair lifting stroke limit member 347 is installed on the upper lifting mounting plate 342 and the lower lifting mounting plate 343. At the same time, a repair lifting position sensor 348 is set on the upper lifting mounting plate 342, the lower lifting mounting plate 343 and the carrier vertical plate of the flower basket lifting platform 341.

[0054] Among them, see Figure 10 The docking section flower basket transfer module 400 uses a robot or a gripper that moves in the overhead space set on the frame.

[0055] The full-wafer basket detection and pre-selection docking device also includes a wafer basket cooling module 500, which is installed across the wafer feeding and docking belt line 100 to cool the full wafer baskets below. In the illustrated example, the wafer basket cooling module 500 utilizes multiple sets of cross-flow air curtains to cool the full wafer baskets below.

[0061] S4, flower basket transfer. After the upper and lower layers are inspected, the full flower baskets that pass the inspection will be directly transferred to the sorting machine by the docking section flower basket transfer module 400.
