[0051] In some embodiments, a main cleaning tank 21 is provided to hold cleaning liquid, and a sub-cleaning tank 22 is provided around the main cleaning tank 21 to hold cleaning liquid overflowing from the main cleaning tank 21, and the main cleaning tank 21 and the sub-cleaning tank 22 are connected by a liquid medicine pipe, so that the cleaning liquid overflowing from the main cleaning tank 21 can enter the sub-cleaning tank 22, and the liquid in the sub-cleaning tank 22 is circulated to the main cleaning tank 21 through the liquid medicine pipe, thereby realizing the circulation and mixing of the liquid in the cleaning tank 2.

[0052] As shown in FIG8 , in some embodiments, an overflow screen plate 23 is provided between the main cleaning tank 21 and the sub-cleaning tank 22. Specifically, the overflow screen plate 23 includes, but is not limited to, being provided on the outer wall of the upper end of the main cleaning tank 21 in a clamping manner and not exceeding the top of the main cleaning tank 21, so that the cleaning liquid overflowing from the main cleaning tank 21 passes through the overflow screen plate 23 and enters the sub-cleaning tank 22. The provision of the overflow screen plate 23 improves the uniformity of the cleaning liquid entering the sub-cleaning tank 22.

[0053] In some embodiments, the wall height of the main cleaning tank 21 is smaller than the wall height of the auxiliary cleaning tank 22; and an overflow port 210 is opened at the upper end of the wall of the main cleaning tank 21 to allow the cleaning liquid in the tank to overflow.

[0054] In some embodiments, a flow balancing mesh plate 24 is provided at the bottom of the main cleaning tank 21; the cleaning liquid in the sub-cleaning tank 22 enters the main cleaning tank 21 through a liquid pipeline (not shown in the figure) through a liquid inlet hole opened at the bottom of the main cleaning tank 21, and the liquid is evenly mixed through the flow balancing holes evenly distributed on the flow balancing mesh plate 24 and then flows into the main cleaning tank 21, thereby improving the uniformity of the liquid and further improving the cleaning effect.

[0055] In some embodiments, a bubbling tube 25 is further provided in the main cleaning tank 21. The bubbling tube 25 is located above the flow equalizing mesh plate 24, and a number of air holes are opened on the tube wall. The bubbling tube 25 supplies gas to the main cleaning tank 21 through an external gas source, and the gas is blown into the main cleaning tank 21 through the air holes, thereby further improving the uniformity of the liquid in the main cleaning tank 21. In addition, the presence of gas enables the cleaning liquid to always maintain a flow circulation, and can clean every part of the silicon wafer, thereby improving the cleaning effect.

[0056] As a preferred embodiment, the main cleaning tank 21 is further connected to a liquid replenishing tube (not shown in the figure), so as to continuously replenish the cleaning liquid into the main cleaning tank 21, so that the cleaning liquid in the main cleaning tank 21 always remains in an overflow state.

[0057] As an optional embodiment, a refill tube is provided at the bottom of the main cleaning tank 21. The cleaning liquid passes through the refill tube and flows through the flow equalizing mesh plate 24 and then enters the main tank. As the cleaning liquid is continuously replenished, the cleaning liquid in the main cleaning tank 21 will overflow from the top of the main cleaning tank 21. The overflowed cleaning liquid flows evenly through the overflow mesh plate 23 and then flows into the sub-cleaning tank 22. The sub-cleaning tank 22 and the main cleaning tank 21 are connected by a liquid pipeline, so that the liquid in the sub-cleaning tank 22 is returned to the main cleaning tank 21, thereby realizing the circulation of the cleaning liquid.

[0058] In some embodiments, due to the rectangular structure of the cleaning tank 2 and the length of its long side, a blower pipe (not shown) and a suction pipe (not shown) are installed above the cleaning tank 2 to further enhance ventilation within the tank. These pipes are typically located above the cleaning tank 2, where harmful gases can be generated. Furthermore, a basket hoist 1 installed above the cleaning tank 2 maintains a bubbling and overflowing state when the basket 4 is placed within the cleaning tank 2, enhancing cleaning efficiency. After cleaning, the basket hoist 1 transports the liquid within the tank to a drying device. A tank cover (not shown) is also provided at the top opening of the main cleaning tank 21 to prevent volatilization of the solution within the main cleaning tank 21.

[0059] In some embodiments, by combining the cleaning tank 2 with the flower basket lifting device 1 and the drying device, the flower basket lifting device 1 can extract the flower basket 4 from the cleaning tank 2 and send it to the drying device, thereby realizing the integration of silicon wafer cleaning and drying.

The transfer device 31 is set to drive the flower baskets 4 to be transferred and dried in sequence along their transfer trajectory, ensuring that each flower basket 4 can be dried the same number of times, thereby improving the accuracy of drying the flower baskets 4. Moreover, the flower baskets 4 are transferred in sequence and loaded and unloaded in an orderly manner only through the transfer device 31, thereby avoiding mutual interference between the taking and placing of the flower baskets 4.

[0062] In some embodiments, a loading and unloading device 34 is further provided below the drying device 32. As a preferred embodiment of the loading and unloading device 34, it includes a vertically arranged tray driving cylinder 341. A tray carrying platform 342 is provided on the telescopic end of the tray driving cylinder 341. A tray for placing the flower basket 4 is provided on the tray carrying platform 342. When the flower basket 4 is placed on the tray carrying platform 342 for loading, the tray driving cylinder 341 pushes the tray carrying platform 342 upward so that the tray carrying platform 342 is aligned with the entrance of the drying box 321 at the bottom layer of the drying device 32. Subsequently, the tray carrying platform 342 is extended into the corresponding drying box 321 through a pushing cylinder (not shown in the figure) to place the flower basket 4 to achieve loading. Similarly, when unloading, the tray carrying platform 342 is extended into the corresponding drying box 321 to take out the flower basket 4, and then the flower basket 4 is transported away from the drying equipment under the retreat of the tray driving cylinder 341.

[0063] In some embodiments, the loading and unloading device 34 further includes a pallet reflux mechanism 343 , which is disposed between the two pallet carrying platforms 342 and is used to transfer the pallets on the two pallet carrying platforms 342 to each other.

[0064] As an optional embodiment, the tray return mechanism 343 includes but is not limited to using a conveyor belt.

[0065] In some embodiments, cylinder doors 322 are provided on both sides of the drying box 321 located at the starting point of the transfer track; and cylinder doors 322 are provided on the side of the remaining drying boxes 321 facing the transfer device 31 .

[0066] As an optional embodiment, the drying box 321 at the bottom layer of the drying device 32 is configured as a drying box 321 located at the starting point of the transfer track, and cylinder doors 322 are provided on both the inner and outer sides thereof, so as to realize loading from the outside and transfer from the inside. The inner side of the remaining drying boxes 321 (the side facing the transfer device 31) is provided with a cylinder door 322, so that the transfer device 31 can extend through the cylinder door 322 to take, place and transfer the flower basket 4.

[0067] In some embodiments, the drying device 32 is configured to include two, and the two drying devices 32 are symmetrically arranged on the left and right, the transfer device 31 is arranged between the two drying devices 32, the transfer bracket of the transfer device 31 is arranged vertically, and the transfer bracket is provided with a driving member for driving the transfer platform 33 to slide up and down, so that the transfer platform 33 can be aligned with the drying boxes 321 at different heights on the left and right drying devices 32 in turn.

[0068] As an optional embodiment, the driving member includes but is not limited to a screw rod or a hydraulic cylinder.

[0069] As shown in Figures 10 and 11, in some embodiments, the transfer platform 33 includes a supporting plate 331, with flower basket limiting plates 332 provided at both ends of the supporting plate 331, and a receiving groove 333 provided at the top of the flower basket limiting plates 332. A shift assembly 335 is provided between the two flower basket limiting plates 332. Specifically, the first reversing cylinder 3351 in the shift assembly 335 drives the first taking plate 3352 to extend into the drying box 321 located on the left side of the transfer platform 33. The limiting step 3353 provided on the first taking plate 3352 is inserted into the gap between the bottom rods of the flower basket 4 (determined according to the actual shape of the flower basket 4, or it can be a groove provided on the bottom plate of the flower basket 4). Then, the first reversing cylinder 3351 retracts, and the first taking plate 3352 pulls the flower basket 4 out of the drying box 321 and onto the supporting plate 331. At this time, the outer bottom rod of the flower basket 4 is inserted into the receiving groove 333, and then the flower basket 4 is transferred. The air moving cylinder 334 pushes the switching assembly 335 to move as a whole, so that the limiting step 3353 on the second taking plate 3354 is stuck in the gap of the bottom rod of the flower basket 4. Since the accommodating groove 333 and the limiting step 3353 are arranged in a perpendicular direction, the limiting step 3353 on the first taking plate 3352 is moved out of the gap of the bottom rod of the flower basket 4, but the flower basket 4 still remains on the supporting plate 331. Then, the second reversing cylinder 3355 pushes the second taking plate 3354 to push the flower basket 4 into the drying box 321 located on the right side of the transfer platform 33, so that the left and right drying boxes 321 of the flower basket 4 are switched.

[0070] In some embodiments, if the flower basket 4 is only shifted up and down within the same drying device 32, it can be achieved by only requiring the first reversing cylinder 3351 or the second reversing cylinder 3355 to drive the corresponding reversing plate to extend and move.

[0071] In some embodiments, the flower basket lifting device 1 is arranged outside the drying device 32 and above the loading and unloading device 34 , and is used to grab and place the flower basket 4 onto the loading and unloading device 34 .

[0073] In some embodiments, if a large number of flower baskets 4 need to be dried, a flower basket series drying method is adopted, that is, the first flower basket 4 is first placed in the starting point of the transfer track (usually the drying box 321 on the bottom layer of the left drying device 32) for drying. When the second flower basket 4 needs to be placed, the first flower basket 4 is first transferred to the second-to-last drying box 321 of the left drying device 32 by the transfer device 31, and then the second flower basket 4 is placed in the drying box 321 on the bottom layer of the left drying device 32, and so on, until the first flower basket 4 is taken out of the drying box 321 on the bottom layer of the right drying device 32 by the loading and unloading device 34.

[0074] As an optional embodiment, when performing direct drying of the flower baskets 4, the flower baskets 4 are placed into the corresponding drying boxes 321 respectively through the transfer device 31; the flower baskets 4 are placed into the drying boxes 321 at the corresponding starting positions respectively through the loading and unloading device 34; and the flower baskets 4 in the drying boxes 321 at the corresponding end positions are taken out respectively through the loading and unloading device 34.

[0075] In some embodiments, if the number of flower baskets 4 to be dried is small, the flower baskets 4 are directly dried, and the two first flower baskets 4 are placed in the drying box 321 at the bottom layer of the left drying device 32 and the drying box 321 at the bottom layer of the right drying device 32, respectively. Then, the transfer device 31 transports the two flower baskets 4 upward to the corresponding drying box 321 to complete drying and then returns them to the drying box 321 at the bottom layer. The flower baskets 4 at the corresponding positions are taken out by the loading and unloading device 34.

The flower basket support frame 362 is fixedly disposed within the drying device 35 and is used to carry the flower basket 4 placed in the drying device 35. The flower basket bracket 361 is movably disposed at the bottom of the flower basket support frame 362. The flower basket bracket 361 can be removed from the drying device 35 by a corresponding drive device to receive the flower basket 4 and then returned to the drying device 35 by the corresponding drive device to place the received flower basket 4 on the flower basket support frame 362 for drying. The positioning slots 363 defined in the flower basket bracket 361 are adapted to mate with the bottom rod of the flower basket 4, allowing the flower basket 4 to be snapped into the positioning slots 363 defined in the flower basket bracket 361, thereby enabling the flower basket 4 to be moved by the flower basket bracket 361.

[0079] Specifically, the driving device includes: a transverse cylinder 364 and a longitudinal cylinder 365; the fixed end of the transverse cylinder 364 is arranged on the inner wall of the drying device 35, and the movable end is connected to the flower basket bracket 361 to push the flower basket bracket 361 to move left and right; the fixed end of the longitudinal cylinder 365 is also arranged on the inner wall of the drying device 35, and its movable end is in contact with the flower basket bracket 361 through a connecting cross bar, so that when the movable end of the longitudinal cylinder 365 is extended, the connecting cross bar is pushed to push the flower basket bracket 361 to move upward.

[0080] In some embodiments, a plurality of drying stations are equidistantly arranged in the drying device 35; a blowing device 37 is provided on the top of each drying station; and the blowing port of the blowing device 37 is arranged facing the drying station.

[0081] As a preferred embodiment, the number of the drying stations is set to 6, and the blowing device 37 arranged on the top of each drying station always maintains a blowing state, so that the flower basket 4 on each drying station is dried by hot air. Specifically, the outline of the blowing chamber of the blowing device 37 is approximately house-shaped, and air inlets (not shown in the figure) are opened on both sides of the blowing chamber, so that the air flow enters the blowing chamber (not shown in the figure), and a number of air guide plates (not shown in the figure) are arranged at intervals in the blowing chamber, and the air guide plates are gradually increased from the two ends of the blowing chamber to the center, so as to increase the air intake speed, and a number of air outlets are opened at the bottom of the blowing chamber, and the air outlets are facing the drying stations, so that the gas is blown toward the flower basket 4.

[0082] As a preferred embodiment, a return air device is also provided at the bottom of each drying station. The return air chamber (not shown in the figure) of the return air device has an outline that is approximately plate-shaped, and an air guide port (not shown in the figure) is provided at the bottom of the return air chamber, and a return air port (not shown in the figure) is provided at the top, which is directly facing the drying station, so that the gas blown out of the blowing port enters the return air chamber through the return air port, and a conical return air plate (not shown in the figure) is provided in the return air chamber, so that the return air is faster.

[0083] As an optional embodiment, the blowing device 37 is connected to the return air device via corresponding pipes (not shown in the figure), thereby realizing the circulation of drying airflow. Furthermore, components such as heaters and filters are additionally provided on the corresponding pipes to further enhance the drying effect of the flower baskets.

[0084] In some embodiments, discharge doors 351 are provided on both sides of the drying device 35 located on the upper layer, so that the upper drying device 35 can be fed from one side and discharged from the other side. A discharge door 351 is provided on either side of the drying device 35 located on the lower layer, and the lower drying device 35 can be fed and discharged on the same side through the discharge door 351. In addition, a gap is provided at the bottom of each discharge door 351 for the flower basket bracket 361 to move out, so that when there is no flower basket 4 on the flower basket bracket 361 to be transported out, the discharge door 351 does not need to be opened, and the flower basket bracket 361 can be moved out from the gap of the discharge door 351; this can improve the drying effect and ensure the temperature inside the drying device 35.

[0085] As an optional embodiment, when the drying device 35 is in the loading state, the flower basket bracket 361 is driven by the transverse cylinder 364 to slide out horizontally; the longitudinal cylinder 365 pushes the sliding flower basket bracket 361 to move up to the receiving position to receive the flower basket 4 lowered by the flower basket lifting device; the discharge door 351 is opened, and the transverse cylinder 364 drives the flower basket bracket 361 to slide horizontally into the drying device 35; the longitudinal cylinder 365 drives the flower basket bracket 361 to move downward and places the flower basket 4 onto the flower basket support frame 362; and when the drying device 35 is in the discharging state, the longitudinal cylinder 365 lifts the flower basket bracket 361, and then the discharge door 351 is opened, and the longitudinal cylinder 365 drives the flower basket bracket 361 to slide horizontally to the discharging position.

[0086] As a preferred embodiment, when the drying device 35 is loading the material for the first time, the flower basket bracket 361 is moved out of the drying device 35 to the receiving position, and receives the flower basket 4 lowered by the flower basket lifting device 1. Then the flower basket bracket 361 is moved back into the drying device 35 to place the received flower basket 4 in the first drying position (the drying position close to the feeding position). When the drying device 35 is about to load the material for the second time, the flower basket bracket 361 is first slid out horizontally. At this time, the flower basket bracket 361 is not in contact with the first drying position. The flower baskets 4 at the drying position come into contact with each other, allowing the flower basket holder 361 to be removed individually. The flower basket holder 361 then rises to the receiving position to receive the flower baskets 4. At this point, the flower baskets 4 at the first drying position are also lifted by the rising flower basket holder 361. When the flower basket holder 361 returns to the drying device 35, the flower basket holder 361 simultaneously moves the second flower basket 4 and the lifted flower basket 4 until the second flower basket 4 is moved above the first drying position. At this point, the first loaded flower basket 4 has moved above the second drying position. The flower basket holder 361 then moves downward, placing the second loaded flower basket 4 on the first drying position and transferring the first loaded flower basket 4 to the second drying position. This cycle repeats until the material is discharged. This loading method of the flower baskets 4 allows the flower baskets 4 to move one position at a time, ensuring a drying effect after passing through three positions.

[0087] In some embodiments, when the drying device 35 located on the upper layer is in the loading state, the drying device 35 located on the lower layer is in the discharging state or the stopping state; and when the drying device 35 located on the lower layer is in the loading state, the drying device 35 located on the upper layer is in the discharging state or the stopping state.

[0088] As a preferred embodiment, when the upper drying device 35 is loading, the flower basket bracket 361 of the upper drying device 35 is moved out, so the flower basket bracket 361 of the lower drying device 35 is not moved out; and when the lower drying device 35 is loading, the flower basket bracket 361 of the lower drying device 35 is moved out, so the flower basket bracket 361 of the upper drying device 35 is not moved out. Even if the drying equipment always maintains the two states of upper in and lower out or lower in and upper out (interlaced), the loading method can avoid the upper flower basket bracket 361 from interfering with the loading and unloading of the bottom layer.

[0089] To sum up, the flower basket lifting device 1 of the present invention is used to extract the flower basket 4 from the cleaning tank 2 and transfer the flower basket 4 to the drying equipment for drying, thereby playing a transfer role. The flower basket lifting device 1, the cleaning tank 2 and the drying equipment are integrated to realize the assembly line operation of silicon wafer cleaning and drying, thereby improving production efficiency.
