Description

Technical Field

[0001] The invention relates to the technical field of solar cells, and more particularly to a solar silicon wafer flower basket. Background Art

[0002] During the production of semiconductor devices, silicon wafers must be strictly cleaned. Even trace amounts of contamination can cause device failure. The purpose of cleaning is to remove surface contamination impurities, including organic and inorganic substances. Some of these impurities exist on the surface of silicon wafers in atomic or ionic states, and some exist in the form of thin films or particles. Organic contamination includes photoresist, organic solvent residues, synthetic wax, and grease or fibers brought by human contact with devices, tools, and utensils. Inorganic contamination includes heavy metals such as gold, copper, iron, and chromium, which seriously affect the minority carrier lifetime and surface conductivity; alkali metals such as sodium, which cause serious leakage; particle contamination includes silicon slag, dust, bacteria, microorganisms, organic colloidal fibers, etc., which can cause various defects. There are two methods for removing contamination: physical cleaning and chemical cleaning.

[0003] When cleaning silicon wafers, it is necessary to use a flower basket with a corresponding structure to load the silicon wafers, and the silicon wafers placed in the flower basket are transferred to a cleaning workshop for thorough cleaning.

DETAILED DESCRIPTION

[0026] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only intended to enable those skilled in the art to better understand and implement the subject matter described herein. In addition, the features described relative to some examples may also be combined in other examples.

[0027] like Figure 1-Figure 8 As shown, a solar silicon wafer flower basket comprises two symmetrically arranged spliced ​​side panels, a sliding track arranged on the spliced ​​side panels, a plurality of limit sliders 5 detachably connected to the sliding track, a limit rod 6 arranged between the two symmetrically arranged limit sliders 5, two limit rod fixing mechanisms 8 respectively sleeved at the two ends of the limit rod 6, two adjusting screw tubes 7 respectively sleeved at the two ends of the limit rod 6 and two limit slider fixing structures 9 symmetrically arranged in the limit slider 5, the limit slider 5 is provided with screw holes, the two ends of the limit rod 6 respectively pass through the corresponding screw holes and are movably connected to the corresponding limit slider 5, one end of the limit rod fixing mechanism 8 is fixedly connected to the limit rod 6, and the other end can slide along the length direction of the limit rod 6, the adjusting screw tube 7 contacts with the other end of the corresponding limit rod fixing mechanism 8, and the outer circumferential surface of the adjusting screw tube 7 is provided with a thread matching the screw hole, and the internal space of the two limit slider fixing structures 9 is communicated with the internal space of the limit rod fixing mechanism 8;

[0028] When the adjusting screw 7 is screwed into the screw hole, the limit rod fixing mechanism 8 is in a shortened state and applies a set pressure to the adjusting screw 7 to form a resistance torque, which is used to limit the limit rod 6 from rotating around its own axis;

[0029] When the limit rod fixing mechanism 8 is in a shortened state, the gas inside it is introduced into the interior of the two limit slider fixing structures 9 to form a set air pressure, and the air pressure drives the two limit slider fixing structures 9 to apply the set pressure to the sliding track.

[0030] It should be noted that when adjusting the flower basket structure according to the silicon wafer of set specifications and shape, the number of limit rods 6 and the opening layout angle of the tooth grooves 601 on the limit rods 6 are set according to the required limit points and edge shapes of the silicon wafers. When adjusting and installing, the limit sliders 5 connected to the two ends of the limit rods 6 are respectively inserted into the corresponding spliced ​​side plates and matched with the sliding rails. The insertion and matching process can be performed successively or simultaneously by a programmed manipulator. Then, the limit rod 6 is rotated by the manipulator so that the tooth grooves 601 on it are arranged according to the set direction, and then the limit rod 6 is clamped to fix it. At this position and layout angle, the adjusting screw tube 7 is rotated to make the adjusting screw tube 7 screwed into the screw hole set on the limit slider 5. As the adjusting screw tube 7 is screwed in, the end of the adjusting screw tube 7 gradually squeezes the limit rod fixing mechanism 8. The movable end of the limit rod fixing mechanism 8 begins to move toward the fixed end under the action of the squeezing force, and it itself is in a gradually compressed state. As the compression amount gradually increases, the deformation elastic force generated by itself reacts to the adjusting screw tube 7 and forms a friction limit with the end of the adjusting screw tube 7, so that the adjusting screw tube 7 can also be locked with the screw hole and form a friction limit on the limit rod fixing mechanism 8. The limit fixation makes the limit rod fixing mechanism 8 locked and unable to rotate around the central axis of the limit rod 6, and the fixed end of the limit rod fixing mechanism 8 is fixedly connected to the limit rod 6, thereby achieving the locking of the limit rod 6, thereby ensuring that the tooth groove 601 on the limit rod 6 can stably point to the set direction to adapt to the shape of the silicon wafer. In the process of the limit rod fixing mechanism 8 being squeezed, the gas inside the limit rod fixing mechanism 8 is squeezed into the limit slider fixing structure 9. After the gas enters the limit slider fixing structure 9, the limit slider fixing structure 9 gradually expands, and the limit slider fixing structure 9 gradually squeezes the slide The track forms a stable internal expansion limit fixation with the sliding track, so that the limit slider 5 can be fixed at the set position on the spliced ​​side panel. The whole installation process is convenient and adjustable. After the silicon wafer is placed, an upper limit rod 6 can be added above the silicon wafer to achieve all-round limit. Therefore, during the cleaning process, the whole flower basket can be rotated to improve the cleaning efficiency. After cleaning, the cleaning liquid can be rotated to shake off, reducing the residual adhesion of the cleaning liquid and improving the processing effect of the subsequent process. The subsequent removal process of the limit rod 6 is also relatively convenient, which can effectively improve the silicon wafer production efficiency.

[0031] In one embodiment of the present invention, Figure 1 As shown, the spliced ​​side panel includes an outer frame plate 1, a circular through groove 101 arranged at the middle position of the outer frame plate 1, an inner frame plate 2 arranged at the center position of the circular through groove 101, and a fixed connecting plate 3 fixedly connected between the outer frame plate 1 and the inner frame plate 2. An arc-shaped sliding area is formed between the outer frame plate 1, the inner frame plate 2 and the fixed connecting plate 3, and a plurality of limit sliding blocks 5 are located in the arc-shaped sliding area.

[0032] It should be noted that when the limit slider 5 connected at both ends of the limit rod 6 is inserted into the spliced ​​side panel, since the two ends of the limit slider 5 are arc surfaces with different arc lengths, it is necessary to align it according to the arc area formed between the outer frame plate 1 and the inner frame plate 2. The two ends of the limit slider 5 can be inserted between the outer frame plate 1 and the inner frame plate 2. The outer frame plate 1 and the inner frame plate 2 are fixedly connected by the fixed connecting plate 3. The strength of the fixed connecting plate 3 needs to be calculated according to the actual rotation speed requirement. While reducing its thickness as much as possible, the set strength is achieved to ensure the connection stability of the outer frame plate 1 and the inner frame plate 2, and maximize the insertion area and adjustment area provided for the limit slider 5.

[0033] In one embodiment of the present invention, Figure 1 As shown, the sliding track includes a first limiting slide groove 102 arranged on the inner circular surface of the circular through groove 101 and a second limiting slide groove 201 arranged on the outer circular surface of the inner frame plate 2. The first limiting slide groove 102 and the second limiting slide groove 201 are both arranged to match the arc sliding area.

[0034] It should be noted that, when the limit slider 5 is inserted into the arc-shaped sliding area formed between the outer frame plate 1, the inner frame plate 2 and the fixed connecting plate 3, its two side surfaces should be flush with the two side surfaces of the outer frame plate 1. At this time, the limit slider fixing structure 9 arranged on the limit slider 5 cooperates with the first limit slide groove 102 and the second limit slide groove 201 respectively arranged on the outer frame plate 1 and the inner frame plate 2, so as to facilitate the subsequent rotation of the adjustment screw tube 7 to limit and fix the limit rod 6, while driving the two limit slider fixing structures 9 arranged on the limit slider 5 to be inserted into the first limit slide groove 102 and the second limit slide groove 201 respectively, and apply a set pressure, thereby forming a stable limit friction, so that the limit slider 5 and the limit rod 6 can be stably in the set installation position and posture in the absence of a large external force.

[0035] In one embodiment of the present invention, Figure 1 As shown, a plurality of connection holes 4 are provided in the middle of the inner frame plate 2 for externally connecting the rotating shaft.

[0036] It should be noted that, during cleaning, the connection hole 4 on the inner frame plate 2 can be connected via an external rotating shaft, so as to achieve the effect of rotating the inner frame plate 2. As the inner frame plate 2 rotates, the outer frame plate 1 and multiple limit rods 6 can be driven to rotate in the same direction and angle through the fixed connecting plate 3, so that the silicon wafer that is fixed by all-round limit can rotate in the cleaning liquid, and can also be rotated to shake off the cleaning liquid after cleaning, so that the remaining cleaning liquid can be quickly shaken off, which can not only reduce the residual adhesion amount of the cleaning liquid, but also improve the efficiency of the subsequent drying treatment.

[0037] In one embodiment of the present invention, Figure 1 , Figure 6-Figure 8 As shown, the limit rod fixing mechanism 8 includes an elastic telescopic air storage component and an annular air guide component arranged at one end of the elastic telescopic air storage component. One end of the elastic telescopic air storage component is fixedly connected to the limit rod 6, and the other end can slide along the length direction of the limit rod 6. The two limit slider fixing structures 9 are connected to the elastic telescopic air storage component through the annular air guide component.

[0038] The elastic telescopic gas storage assembly includes a fixed ring body 801 fixedly connected to the limit rod 6, a movable ring body 802 slidably connected to the limit rod 6, an outer telescopic bellows 803 connected between the fixed ring body 801 and the movable ring body 802, an inner telescopic bellows 804 and a first spring 805. A sealed gas storage chamber is formed between the fixed ring body 801, the movable ring body 802, the outer telescopic bellows 803 and the inner telescopic bellows 804, and the first spring 805 is located in the sealed gas storage chamber.

[0039] The annular gas guide assembly includes an annular groove 806 arranged on the outer circumferential surface of the fixed ring body 801, a first gas channel 807 arranged inside the fixed ring body 801, and two sealing rings 808 connected to the outer circumferential surface of the fixed ring body 801. The two sealing rings 808 are symmetrically distributed on both sides of the annular groove 806, and the annular groove 806 is connected to the sealed gas storage chamber through the first gas channel 807.

[0040] It should be noted that, as mentioned above, after the layout angle of the tooth groove 601 on the limit rod 6 is adjusted, the limit rod 6 is clamped by an external manipulator to keep it in a stable state, and the adjusting screw 7 is rotated at the same time, so that the adjusting screw 7 is gradually screwed into the screw hole on the limit slider 5. As the adjusting screw 7 is screwed in, the movable ring body 802 is gradually squeezed. After being subjected to force, the movable ring body 802 moves toward the fixed ring body 801 and begins to squeeze the outer telescopic bellows 803, the inner telescopic bellows 804 and the first spring 805. As the first spring 805 is squeezed and shortened, the elastic deformation force generated by it gradually increases and acts on the adjusting screw 7, so that the thread between the adjusting screw 7 and the screw hole is in a tightly squeezed and locked state. State, at this time, the adjusting screw 7 and the screw hole are in a stable connection state, and a friction force is generated on the movable ring body 802. When the movable ring body 802 cannot overcome the resistance torque formed by the friction force, it will be in a fixed state and no longer rotate. In the absence of a large external force, the fixed ring body 801 and the limit rod 6 can be stabilized in this state. Since a stable limit is also formed between the adjusting screw 7 and the limit slider 5, a stable connection state can be formed between the limit rod 6 and the limit slider 5. Due to the rotation restriction effect of the outer telescopic bellows 803, the inner telescopic bellows 804 and the first spring 805, even if the adjusting screw 7 is rotating, it cannot drive the movable ring body 802 to rotate.

[0041] In one embodiment of the present invention, a sliding limiter may be provided between the movable ring body 802 and the limit rod 6, that is, a protrusion is provided on the movable ring body 802, and a sliding groove matching the protrusion is provided on the limit rod 6, which can further improve stability;

[0042] At the same time, with the extrusion process of the inner telescopic bellows 804 and the first spring 805, the internal volume of the sealed air storage chamber gradually decreases, and the internal air pressure gradually increases. Under the action of the air pressure, the gas inside flows through the first gas channel 807 and the annular groove 806 in sequence and then enters the limit slider fixing structure 9. The annular channel formed by the annular groove 806 and the sealing ring 808 can enable the limit rod 6 to always maintain a connected state with the limit slider fixing structure 9 during the rotation process.

[0043] Among them, a first damping layer is connected to one end surface of the movable ring body 802, and a second damping layer matching with the first damping layer is provided on the adjusting spiral tube 7.

[0044] It should be noted that in order to further increase the resistance torque generated between the adjusting screw 7 and the movable ring body 802, by providing a first damping layer and a second damping layer that cooperate with each other on the movable ring body 802 and the adjusting screw 7, the value of the friction force can be effectively increased, thereby increasing the value of the resistance torque.

[0045] In one embodiment of the present invention, Figure 1 , Figure 3-Figure 5 As shown, the limiting slider fixing structure 9 includes a sliding chamber 901 arranged inside the limiting slider 5, a block 902 slidably connected to the inner wall of the sliding chamber 901, a telescopic sleeve 903 and a second spring 904 connected between the block 902 and the inner wall of the sliding chamber 901, and a second gas channel 905 arranged inside the limiting slider 5, a sealed cavity is formed between the block 902, the telescopic sleeve 903 and the inner wall of the sliding chamber 901, one end of the second gas channel 905 is connected to the sealed cavity, one end of the second spring 904 passes through the sliding chamber 901, one end of the second spring 904 is provided with an arc surface matching the outer circular surface of the inner frame plate 2 or the inner circular surface of the circular through groove 101, and a third damping layer is connected to the arc surface.

[0046] It should be noted that the elastic force of the second spring 904 in the limit slider fixing structure 9 is smaller than the elastic force of the first spring 805. During the resetting process, the first spring 805 can draw back the gas in the sealed cavity through the change of air pressure, and make the second spring 904 in a compressed state, so that the block 902 can be retracted into the sliding chamber 901, so that the limit slider 5 can be drawn out from between the outer frame plate 1 and the inner frame plate 2. When the limit rod fixing mechanism 8 is in a compressed state, the internal gas is discharged from the annular groove 806 and flows through the second gas channel 905 into the sealed cavity. At this time, the second spring 904 is no longer deformed by force. Under the action of the elastic force of the second spring 904 and the air pressure, the block 902 can be pushed out of the sliding chamber 901 and contact the outer frame plate 1 or the inner frame plate 2, and gradually generate a set pressure, thereby forming a limiting friction force to prevent the limit slider 5 from sliding in the arc sliding area between the outer frame plate 1 and the inner frame plate 2, forming a stable limiting effect.

[0047] In one embodiment of the present invention, Figure 1 and Figure 6 As shown, both ends of the limit rod 6 are connected with connecting pieces 602, and the limit rod 6 is movably connected with the corresponding limit slider 5 through the connecting piece 602. The limit rod 6 is provided with a plurality of equally spaced tooth grooves 601, and the tooth grooves 601 are used to limit and fix the silicon wafer.

[0048] It should be noted that both limit sliding blocks 5 are provided with connecting grooves that match the shape of the connecting member 602 .

[0049] The present embodiment is described above, but the present embodiment is not limited to the above-mentioned specific implementation manner. The above-mentioned specific implementation manner is merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, which are all within the protection of the present embodiment.
