[0026] The utility model is now further described with reference to the accompanying drawings.
[0027] Embodiment 1
[0028] like Figures 1 to 6 As shown, a flower basket turning device for large-capacity tank-type cleaning includes a double-layer flower basket 4, a turning platform 3 and a turning drive device. A plurality of "J"-shaped hook grooves 42 are provided on both end plates of the double-layer flower basket 4; two turning grooves 31 are symmetrically provided on the turning platform 3, and both ends of the turning platform 3 are rotatably installed in the cleaning groove 12 of the cleaning device; the turning drive device is installed on the cleaning device and connected to the turning platform 3, and the double-layer flower basket 4 is movably placed in the turning groove 31, and the turning drive device drives the turning platform 3 to turn the double-layer flower basket 4 from a vertical state to a horizontal state.
[0029] The double-layer flower basket 4 is equivalent to merging two existing flower baskets into one flower basket, so that one flower basket can hold 200 silicon wafers. The rummaging groove 31 is equipped with two flipping platforms 3, so that 800 wafers can be flipped. The double-layer flower basket 4 can be used in common with other existing devices. The flower basket includes two end plates and a plurality of connecting columns. The end plates are provided with a plurality of hooking grooves 42. The connecting columns are provided with an array of 200 slots, and the silicon wafers are inserted into the slots. The double-layer flower basket 4 makes the structure more compact and facilitates the simplification of the structure of the hook device, which can not only improve efficiency, but also make the control simpler and reduce costs.
[0030] The double-layer flower basket 4 is turned over to a horizontal state so that the two layers of silicon wafers are not overlapped, thereby preventing the liquid of the upper layer of silicon wafers from dripping onto the lower layer of silicon wafers, thereby improving the efficiency of dehydration and draining.
[0031] Two turning grooves 31 are symmetrically arranged inside the turning platform 3, and both ends are provided with avoidance grooves 33 for exposing the hook groove 42, and the avoidance grooves 33 are communicated with the turning grooves 31. The turning groove 31 is L-shaped, and the top and one side are open, which is convenient for loading the double-layer flower basket 4. A plurality of guide blocks 32 are symmetrically arranged at both ends of the turning groove 31. Specifically, two guide blocks 32 are arranged on each adjacent vertical side, and the guide blocks 32 are provided with guide slopes 321. When the flower basket is inserted into the turning groove 31, the guide slopes 321 are used to guide the double-layer flower basket 4 so that the double-layer flower basket 4 falls into the center of the turning groove 31, thereby ensuring that appropriate space is left between the two ends of the double-layer flower basket 4 and the turning platform 3, so that the hook device can grab the double-layer flower basket 4.
[0032] During the turning process, the double-layer flower basket 4 will be displaced, and the guide block 32 can limit the position of the double-layer flower basket 4 so that the displacement caused by the turning can be controlled.
[0033] The flipping drive device includes a flipping bracket 21, a driven pulley 24, a driving pulley 26, a flipping synchronous belt 25, a flipping motor 27 and a flipping shaft 23. The flipping shafts 23 are symmetrically arranged at both ends of the flipping platform 3 and are located on the center line of the flipping platform 3. The flipping shafts 23 are installed on the flipping bracket 21 through bearing seats 22. The flipping bracket 21 is installed in the cleaning tank 12 and is located at both ends of the cleaning tank 12. A driven pulley 24 is installed on one of the flipping shafts 23. The flipping motor 27 is installed on the cleaning device and is located above the cleaning tank 12. A driving pulley 26 is installed on the flipping motor 27. The driving pulley 26 is connected to the driven pulley 24 through the flipping synchronous belt 25. The flipping motor 27 is a reduction motor. The flipping motor 27 drives the flipping platform 3 to rotate through the driving pulley 26, the flipping synchronous belt 25 and the driven pulley 24. The transmission structure is simple and plastic parts can be used, which is corrosion-resistant. That is, the bearing seats 22, the flipping brackets 21, the bearings, the driving pulleys 26, the driven pulleys 24 and the flipping synchronous belts 25 are all made of non-metallic materials and are flame-retardant, high-temperature resistant, corrosion-resistant and do not shed powder.
[0034] For the cleaning of the last pickling, it is transported from the pickling tank to the cleaning tank 12 by the transfer device 5 for cleaning. The double-layer flower basket is flipped by 90° in the cleaning tank 12, and then the transfer device transports the double-layer flower basket 4 to the slow lifting pre-dehydration.
[0035] In the cleaning tank 12, the double-layer flower basket 4 is flipped by 90°. After slow lifting and pre-dehydration, it is transported to the tunnel drying. It is equivalent to changing the original double-layer silicon wafer flower basket to a single-layer flower basket for complete drying of the silicon wafers in the tunnel drying. And the drying time can be reduced to 500S, reducing the acid consumption, alkali consumption, electricity consumption and water consumption per single silicon wafer, and enabling the overall production capacity to reach 16,000 pcs / h, greatly improving the production efficiency.
[0036] The silicon wafers cannot be exposed to the air with liquid for too long. Therefore, the flipping of the double-layer flower basket 4 can only be carried out in the liquid in the cleaning tank 12 to ensure that the silicon wafers will not have water marks due to being exposed to the air for too long.
[0037] There are technical difficulties in the flower basket flipping device for large-production-capacity trough cleaning, which is to transfer the flower basket vertically by the manipulator to horizontally by the manipulator, ensuring the technical connection for the next horizontal drying of the silicon wafers.
[0038] Embodiment 2
[0039] On the basis of the above embodiment, as Figures 1 to 6As shown in the figure, a cleaning device for large-capacity tank cleaning includes a basket turning device for large-capacity tank cleaning, a cleaning tank 12, a cleaning rack 11, and a transfer device 5. The cleaning tank 12 is installed on the cleaning rack 11 and there are two of them. The transfer device 5 is installed on one side of the cleaning tank 12 and is used for lifting and moving the double-layer basket 4. There are two cleaning tanks 12 installed inside the cleaning device.
[0040] The transfer device 5 includes a horizontal linear module, a vertical linear module, a grasping arm 52, a hook device, and a hanging-in detection device 55. The horizontal linear module is arranged on the cleaning rack 11 and is located at one end of the cleaning tank 12. The vertical linear module is installed on the slide table of the horizontal linear module, and the grasping arm 52 is installed on the slide table of the vertical linear module. Both the horizontal linear module and the vertical linear module are prior arts. Similar deformed structures of linear modules can also be used to achieve the functions of horizontal and vertical movement, which are all conventional technologies and will not be described in detail here. The grasping arm 52 is L-shaped and includes a lifting arm 521 and a horizontal arm 522 that are perpendicular to each other. The lifting arm 521 is installed on the slide table of the vertical linear module, and the horizontal arm 522 is connected to the hook device. The hook device is used to insert into the hook slot 42 of the double-layer basket 4; the hanging-in detection device 55 is installed on the hook device and is used to detect whether the double-layer basket 4 is loaded.
[0041] The hook device includes a hook plate 53 and a hook rod 54. The hook plate 53 is installed on the horizontal arm 522 and is arranged along the length direction of the horizontal arm 522. There are three hook plates 53, which are arranged at equal intervals. Two hook rods 54 are installed on each of the hook plates 53 at both ends, and four hook rods 54 are installed on the middle hook plate 53, and there are two hook rods 54 on each side. The hook rods 54 correspond to the hook slots 42 on the double-layer basket 4 one by one. The hook slots 42 are used to insert into the upward limit slots in the hook slots 42, which can prevent the basket from detaching from the hook rods 54 during the transfer process and improve the reliability and stability of the transfer.
[0042] To further improve the efficiency, it further includes: a connecting plate 56. The connecting plate 56 is installed on the horizontal arm 522 of the grasping arm 52, and the hook plates 53 are installed at both ends of the connecting plate 56, which can simultaneously grasp four double-layer baskets 4 and realize the transfer of 800 silicon wafers, greatly improving the efficiency.
[0043] The hanging-in detection device 55 includes a microswitch. The microswitch is installed on the hook plate 53 and is located inside. The microswitch is arranged opposite to the connecting rod of the double-layer basket 4. When the hook rod 54 is inserted into place in the hook slot 42, the microswitch is pushed by the connecting rod, and the microswitch emits a signal. The control system can perform the grasping and releasing of the basket according to the feedback of the microswitch.
[0044] The transfer device 5 can extract two double-layer flower baskets 4 at a time, which can improve efficiency. The overall production capacity can directly increase from 9600 pcs / h to 16000 pcs / h. The acid consumption, alkali consumption, electricity consumption, and water consumption per single silicon wafer can be reduced. The flower basket changes from the vertical direction to the horizontal direction, enabling connection to the drying process.
[0045] It can be used in the wet tank equipment processes of various batteries such as TOPCON, XBC, PRC, and HJT.
[0046] During operation, the transfer device 5 first transports two double-layer flower baskets 4 from the pickling tank and places them above one of the cleaning tanks 12. The vertical linear module drives the double-layer flower basket 4 to descend until the double-layer flower basket 4 enters the flipping tank 31. Then, the vertical linear module continues to drive the hook rod 54 downward to disengage the hook rod 54 from the limiting groove of the hook slot 42. Then, the horizontal linear module drives the hook rod 54 to move outward from the double-layer flower basket 4 until the hook rod 54 moves to the outside of the double-layer flower basket 4. Then, the vertical linear module drives the hook rod 54 to rise. Next, the flipping device flips the vertically positioned double-layer flower basket 4 to the horizontal state. When the double-layer flower basket 4 is being flipped, the transfer device 5 moves into the pickling tank to grab another set of double-layer flower baskets 4. The flipped double-layer flower basket 4 is grabbed by the transfer device 5 of the drying device, slowly lifted for pre-dehydration, and then transported to the chain for tunnel drying, thus completing one cycle of the flower basket flipping operation.
