Abstract
Description
Technical Field
[0001] This utility model relates to the field of solar cell technology, and in particular to a storage device and solar cell production equipment. Background Technology
[0002] In the process of solar cell production, in order to analyze temporary situations such as production line abnormalities, it is necessary to buffer the solar cell silicon wafers on the conveyor line. However, in the existing solar cell production equipment, the solar cell silicon wafers are directly removed from the conveyor line by hand, which is inefficient and easily causes bumps and damage to the solar cell silicon wafers, affecting the production quality of solar cells. Utility Model Content
[0003] Therefore, it is necessary to provide a storage device and solar cell production equipment that improves upon the aforementioned defects, addressing the problems of poor buffering efficiency and easy damage to silicon wafers in existing solar cell production equipment.
[0004] This application provides a storage device for storing solar cell silicon wafers on a conveyor line, the storage device comprising:
[0005] A first plate and a second plate are disposed on both sides of the conveyor line along a first direction. A plurality of first protrusions and second protrusions are respectively disposed on the surfaces of the first plate and the second plate that are close to each other, so as to form a storage part for placing the solar cell silicon wafer between the first protrusions and the second protrusions.
[0006] When the conveyor line transports the solar cell silicon wafer, the solar cell silicon wafer extends out of the conveyor line along the first direction and is located in the storage section, and the first plate and the second plate are movable along a third direction to drive the solar cell silicon wafer closer to or away from the conveyor line, the third direction being perpendicular to the first direction.
[0007] By movably arranging the first and second plates along a third direction, when it is necessary to buffer solar cell silicon wafers, the first and second plates move away from the conveyor line along the third direction, thereby moving the solar cell silicon wafers located in the storage section away from the conveyor line, thus completing the collection and storage of solar cell silicon wafers. When it is necessary to release solar cell silicon wafers, the first and second plates move closer to the conveyor line along the third direction, thereby moving the solar cell silicon wafers located in the storage section closer to the conveyor line. Subsequently, the solar cell silicon wafers come into contact with the conveyor line and are conveyed out of the storage section, completing the transfer of solar cell silicon wafers from the storage device to the conveyor line.
[0008] In some embodiments, the upper surfaces of the first protrusion and the second protrusion are inclined.
[0009] In some embodiments, the storage device further includes a sensor communicatively connected to the first board and the second board to control the movement of the first board and the second board along the third direction.
[0010] In some embodiments, when storing solar cell silicon wafers, when the sensor detects the solar cell silicon wafers on the conveyor line, the first plate and the second plate move away from the conveyor line along the third direction to carry the solar cell silicon wafers away from the conveyor line and store them in the storage unit;
[0011] When releasing the solar cell silicon wafer, if the sensor detects that the solar cell silicon wafer is not present on the conveyor line, the first plate and the second plate move closer to the conveyor line along the third direction to place the solar cell silicon wafer into the conveyor line.
[0012] In some embodiments, the storage device further includes a third board that connects the first board and the second board along a second direction perpendicular to the first direction and the third direction.
[0013] In some embodiments, the storage device further includes a holding member disposed on the side of the third plate opposite to the storage portion, for transporting the storage device.
[0014] In another aspect, this application provides a solar cell manufacturing apparatus, comprising:
[0015] The aforementioned storage device; and
[0016] A conveyor line is disposed between the first plate and the second plate along the first direction. The conveyor line conveys the solar cell silicon wafer along the second direction. The conveying plane of the conveyor line is higher than the storage section. The solar cell silicon wafer extends out of the conveyor line along the first direction and is located in the storage section. The second direction is perpendicular to the first direction and the third direction.
[0017] In some embodiments, the first plate and the second plate are movably disposed on both sides of the conveyor line along the third direction.
[0018] In some embodiments, the first plate and the second plate are detachably mounted on both sides of the conveyor line along the first direction.
[0019] In some embodiments, the solar cell manufacturing equipment further includes a frame extending along the third direction, wherein the first plate and the second plate are movably disposed on the frame along the third direction. Attached Figure Description

[0039] To better understand the embodiments of this application, the following is combined with... Figures 1 to 5 The embodiments of this application will be described in detail.
[0040] like Figure 1 and Figure 2 As shown, this application provides a storage device 1 for storing solar cell silicon wafers 4 on a conveyor line 2. The storage device 1 includes a first plate 11 and a second plate 12 disposed on both sides of the conveyor line 2 along a first direction X. A plurality of first protrusions 111 and second protrusions 121 are respectively disposed on the surfaces of the first plate 11 and the second plate 12 that are close to each other, so as to form a storage part 13 for placing the solar cell silicon wafers 4 between the first protrusions 111 and the second protrusions 121. When the conveyor line 2 conveys the solar cell silicon wafers 4, the solar cell silicon wafers 4 extend out of the conveyor line 2 along the first direction X and are located in the storage part 13. The first plate 11 and the second plate 12 are movable along a third direction Z to drive the solar cell silicon wafers 4 to move closer to or away from the conveyor line 2. The third direction Z is perpendicular to the first direction X.
[0041] On the surfaces of the first plate 11 and the second plate 12 that are close to each other, a plurality of first protrusions 111 and second protrusions 121 are respectively provided, specifically, as shown in... Figures 1 to 4 As shown, a plurality of first protrusions 111 are provided on the surface of the first plate 11 near the second plate 12, and the plurality of first protrusions 111 are arranged along the third direction Z. Similarly, a plurality of second protrusions 121 are provided on the surface of the second plate 12 near the first plate 11, and the plurality of second protrusions 121 are also arranged along the third direction Z. Storage sections 13 are formed between the first protrusions 111 and the second protrusions 121 correspondingly arranged along the first direction X, that is, the storage device 1 is provided with a plurality of storage sections 13, and the plurality of storage sections 13 are also arranged along the third direction Z. When storing solar cell silicon wafers 4, the plurality of solar cell silicon wafers 4 are respectively stored in the storage sections 13, that is, the plurality of solar cell silicon wafers 4 are also arranged along the third direction Z.
[0042] The first protrusion 111 and the second protrusion 121 protrude from the first plate 11 and the second plate 12 respectively along the first direction X. In some embodiments, the upper surfaces of the first protrusion 111 and the second protrusion 121 are arranged parallel to the first direction X to form a horizontal plane parallel to the first direction X between them, so as to ensure that the solar cell silicon wafer 4 can be stably stored in the storage part 13. In other embodiments, the upper surfaces of the first protrusion 111 and the second protrusion 121 are inclined to the first direction X. In this case, the solar cell silicon wafer 4 contacts the upper surfaces of the first protrusion 111 and the second protrusion 121 under the action of gravity, which can also realize the storage of the solar cell silicon wafer 4.
[0043] In some embodiments, the first protrusion 111 may be composed of a plurality of protrusions protruding from the first plate 11 along the first direction X, and the plurality of protrusions are spaced apart along the second direction Y to ensure that the solar cell silicon wafer 4 can be stably stored in the storage compartment 13. In other embodiments, the first protrusion 111 may also be composed of a single protrusion protruding from the first plate 11 along the first direction, and the protrusion extends a certain distance along the second direction Y to ensure that the solar cell silicon wafer 4 can be stably stored in the storage compartment 13.
[0044] Similarly, the second protrusion 121 can also be composed of one or more protrusions protruding from the second plate 12 along the first direction X. It should be noted that the first protrusion 111 and the second protrusion 121 can have the same number of protrusions or different numbers of protrusions, and this application embodiment does not limit this.
[0045] When the conveyor line 2 transports the solar cell silicon wafer 4, the solar cell silicon wafer 4 extends out of the conveyor line 2 along the first direction X and is located in the storage section 13. That is, the size of the solar cell silicon wafer 4 along the first direction X is larger than the size of the conveyor line 2, so as to ensure that the solar cell silicon wafer 4 can be secured in the storage section 13 when the first plate 11 and the second plate 12 move along the third direction Z. Furthermore, the size of the solar cell silicon wafer 4 along the first direction X should also be larger than the minimum distance between the first protrusion 111 and the second protrusion 121 along the first direction X, to ensure that the solar cell silicon wafer 4 can be stored in the storage section 13 without falling out. Also, the minimum distance between the first protrusion 111 and the second protrusion 121 along the first direction X should also be larger than the size of the conveyor line 2 along the first direction X, to ensure that the first plate 11 and the second plate 12 will not interfere with or collide with the conveyor line 2 when they move along the third direction Z.
[0046] The first plate 11 and the second plate 12 are movable along the third direction Z. Specifically, the movable arrangement of the first plate 11 and the second plate 12 along the third direction Z can be achieved by a lead screw or by a guide rail slider mechanism. This application embodiment does not limit this.
[0047] like Figure 4 and Figure 5 As shown, during normal production, that is, when the solar cell silicon wafer 4 does not need to be stored, the conveying plane 21 of the conveying line 2 is higher than the first protrusion 111 and the second protrusion 121 to ensure that the solar cell silicon wafer 4 can pass smoothly through the storage section 13 without interfering with the first protrusion 111 and the second protrusion 121.
[0048] When it is necessary to store the solar cell silicon wafer 4, the first plate 11 and the second plate 12 move upward along the third direction Z, so that the solar cell silicon wafer 4 located in the storage section 13 abuts against the first protrusion 111 and the second protrusion 121. Then, the first plate 11 and the second plate 12 drive the solar cell silicon wafer 4 located in the storage section 13 to move upward, thereby taking the solar cell silicon wafer 4 off the conveyor line 2 and storing it in the storage device 1. Similarly, the next solar cell silicon wafer 4 on the conveyor line 2 is stored in the storage section 13 of the next layer, completing the sequential storage of the solar cell silicon wafers 4 on the conveyor line 2.
[0049] When it is necessary to release the solar cell silicon wafer 4, the first plate 11 and the second plate 12 move downward along the third direction Z, causing the solar cell silicon wafer 4 located in the storage section 13 to move downward. When it descends to a certain height, the solar cell silicon wafer 4 contacts the conveying plane 21 of the conveying line 2 and simultaneously disengages from the first protrusion 111 and the second protrusion 121, allowing the solar cell silicon wafer 4 to be placed back on the conveying line 2 and released from the storage device 1 under the conveying of the conveying line 2. Similarly, the next solar cell silicon wafer 4 stored in the storage section 13 on the upper layer of the storage device 1 is then placed back on the conveying line 2, completing the sequential release of the solar cell silicon wafers 4 in the storage device 1.
[0050] It can be seen that the solar cell silicon wafer 4 is first stored in storage device 1 and then put back on the conveyor line 2 during the entire buffering process. Therefore, in practical applications, two storage devices 1 can be set up to ensure that the final conveying order of the solar cell 4 is consistent with that before storage.
[0051] By making the first plate 11 and the second plate 12 movable along the third direction Z, the storage and release of the solar cell silicon wafer 4 can be completed automatically and conveniently without manual handling. This improves production efficiency and effectively avoids damage to the solar cell silicon wafer 4 from bumps and knocks.
[0052] like Figure 4 and 5 As shown, in some embodiments, the upper surfaces of the first protrusion 111 and the second protrusion 121 are inclined.
[0053] The upper surfaces of the first protrusion 111 and the second protrusion 121 are inclined, that is, the upper surfaces of the first protrusion 111 and the second protrusion 121 are set at a certain angle to the horizontal plane. The lower surfaces of the first protrusion 111 and the second protrusion 121 can be either horizontal or inclined, and this embodiment does not limit this.
[0054] By tilting the upper surfaces of the first protrusion 111 and the second protrusion 121, when storing the solar cell silicon wafer 4, the lower surface of the solar cell silicon wafer 4 abuts against the upper surfaces of the first protrusion 111 and the second protrusion 121. At this time, because the upper surfaces of the first protrusion 111 and the second protrusion 121 are tilted, the solar cell silicon wafer 4 is in line contact with the first protrusion 111 and the second protrusion 121 (i.e., the contact portion forms a straight line), ensuring stable storage of the solar cell silicon wafer 4 even if there are errors in the installation of the first protrusion 111 and the second protrusion 121. In contrast, when the upper surfaces of the first protrusion 111 and the second protrusion 121 are horizontal, because the solar cell silicon wafer 4 is in surface contact with the first protrusion 111 and the second protrusion 121, installation errors can cause the upper surfaces of the two protrusions to not be on the same horizontal plane, further leading to tilting or even damage from impacts during storage of the solar cell silicon wafer 4.
[0055] Therefore, the upper surfaces of the first protrusion 111 and the second protrusion 121 are tilted, so that the storage device 1 has a larger fault tolerance space, and even if there are errors in the installation of the first protrusion 111 and the second protrusion 121, the solar cell silicon wafer 4 can be stored stably.
[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the storage device 1 further includes a sensor 14, which is communicatively connected to the first board 11 and the second board 12 to control the first board 11 and the second board 12 to move along the third direction Z.
[0057] The status of the solar cell silicon wafers 4 on the conveyor line 2 can be monitored by setting sensor 14.
[0058] When storing solar cell silicon wafers 4, sensor 14 monitors the solar cell silicon wafers 2 on the conveyor line 2. When the presence of solar cell silicon wafers 4 on the conveyor line 2 is detected, sensor 14 sends a command to the control system, thereby controlling the first plate 11 and the second plate 12 to move upward along the third direction Z, thereby collecting the solar cell silicon wafers 4 on the conveyor line 2 into the storage unit 13, ensuring the accurate storage of solar cell silicon wafers 4.
[0059] When releasing the solar cell silicon wafer 4, the sensor 14 monitors the solar cell silicon wafer 2 on the conveyor line 2. When it detects that there is no solar cell silicon wafer 4 on the conveyor line 2, the sensor 14 controls the first plate 11 and the second plate 12 to move downward along the third direction Z, thereby placing the solar cell silicon wafer 4 on the storage unit 13 back onto the conveyor line 2, ensuring the accurate release of the solar cell silicon wafer 4.
[0060] By setting up the monitor 14, it is possible to ensure that the solar cell silicon wafers 4 are accurately and neatly stored on the storage device 1, and to ensure that the solar cell silicon wafers 4 are orderly returned to the conveyor line 2. It can accurately control the movement of the first plate 11 and the second plate 12, and effectively avoid mutual collisions when the solar cell silicon wafers 4 are stored and released.
[0061] like Figure 1 and Figure 2 As shown, in some embodiments, when storing solar cell silicon wafer 2, when sensor 14 senses solar cell silicon wafer 4 on conveyor line 2, the first plate 11 and the second plate 12 move away from conveyor line 2 along the third direction Z to carry solar cell silicon wafer 4 away from conveyor line 2 and store it in storage unit 13; when releasing solar cell silicon wafer 4, when sensor 14 senses that there is no solar cell silicon wafer 4 on conveyor line 2, the first plate 11 and the second plate 12 move closer to conveyor line 2 along the third direction Z to place solar cell silicon wafer 4 into conveyor line 2.
[0062] like Figures 1 to 4 As shown, in some embodiments, the storage device 1 further includes a third board 15, which connects the first board 11 and the second board 12 along a second direction Y, which is perpendicular to the first direction X and the third direction Z.
[0063] On the one hand, by setting the third plate 15, the top of the storage unit 13 along the third direction Z can be sealed, which can effectively prevent dust and other impurities from falling onto the solar cell silicon wafer 4 and ensure the cleanliness of the solar cell silicon wafer 4; on the other hand, by setting the third plate 15, the first plate 11 and the second plate 12 are connected together, so that the two can become a whole, which facilitates the handling of the storage device 1.
[0064] like Figures 1 to 4 As shown, in some embodiments, the storage device 1 further includes a holding member 16, which is disposed on the side of the third plate 15 away from the storage section 13, for transporting the storage device 1.
[0065] By setting up the gripper 16, when it is necessary to move the storage device 1, simply grab the gripper 16 to easily move the storage device 1 to the destination. In this way, the collected solar cell silicon wafers 4 can be easily moved from one conveyor line to another.
[0066] like Figures 3 to 5 As shown, this application also provides a solar cell manufacturing apparatus, including a storage device 1 and a conveyor line 2. The conveyor line 2 is disposed between a first plate 11 and a second plate 12 along a first direction X, and conveys solar cell silicon wafers 4 along a second direction Y. The conveying plane 21 of the conveyor line 2 is higher than the storage unit 13. The solar cell silicon wafers 4 extend from the conveyor line 2 along the first direction X and are located within the storage unit 13. The second direction Y is perpendicular to the first direction X and the third direction Z.
[0067] Conveyor line 2 refers to a component that moves along the second direction Y. Specifically, conveyor line 2 can be a belt or other conveyor belt, or a chain conveyor mechanism; this application embodiment does not limit this. During the movement of conveyor line 2 along the second direction Y, the solar cell silicon wafer 4 is also conveyed along the second direction Y.
[0068] The solar cell silicon wafer 4 extends out of the conveyor line 2 along the first direction X and is located within the storage section 13. Specifically, the size of the solar cell silicon wafer 4 along the first direction X is larger than the size of the conveyor line 2 to ensure that the solar cell silicon wafer 4 can be secured within the storage section 13 when the first plate 11 and the second plate 12 move along the third direction Z. Furthermore, the size of the solar cell silicon wafer 4 along the first direction X should also be larger than the minimum distance between the first protrusion 111 and the second protrusion 121 along the first direction X to ensure that the solar cell silicon wafer 4 can be stored within the storage section 13 without falling out.
[0069] like Figure 5 As shown, during the transport process, the transport plane 21 of the transport line 2 is higher than the storage section 13. Specifically, the transport plane 21 of the transport line 2 is higher than the first protrusion 111 and the second protrusion 121 to ensure that the solar cell silicon wafer 4 can pass smoothly through the storage section 13 without interfering with the first protrusion 111 and the second protrusion 121.
[0070] By setting up the storage device 1 and the conveyor line 2, when it is necessary to store solar cell silicon wafers 4 during the production of solar cells, the first plate 11 and the second plate 12 move upward along the third direction Z, so that the solar cell silicon wafers 4 located in the storage section 13 abut against the first protrusion 111 and the second protrusion 121. Subsequently, the solar cell silicon wafers located in the storage section 13 are moved upward, thereby carrying the solar cell silicon wafers 4 on the conveyor line 2 away from the conveyor line 2 and storing them in the storage device 1. Similarly, the next solar cell silicon wafer 4 on the conveyor line 2 is stored in the storage section 13 of the next layer, completing the sequential storage of solar cell silicon wafers 4 on the conveyor line 2.
[0071] When it is necessary to release the solar cell silicon wafer 4, the first plate 11 and the second plate 12 move downward along the third direction Z, causing the solar cell silicon wafer located in the storage section 13 to move downward. When it descends to a certain height, the conveying plane 21 of the solar cell silicon wafer 4 conveying line 2 contacts and disengages from the first protrusion 111 and the second protrusion 121, so that the solar cell silicon wafer 4 is placed back on the conveying line 2 and released from the storage device 1 under the conveying of the conveying line 2. Similarly, the next solar cell silicon wafer 4 stored in the storage section 13 of the upper layer of the storage device 1 is then placed back on the conveying line 2, completing the sequential release of the solar cell silicon wafers 4 in the storage device 1.
[0072] In some embodiments, the first plate 11 and the second plate 12 are movably disposed on both sides of the conveyor line 2 along a third direction Z.
[0073] Specifically, guide rails extending in the third direction Z can be respectively provided on the surfaces of the first plate 11 and the second plate 12 that are close to each other, and sliders are provided on both sides of the conveyor line 2. The movement of the first plate 11 and the second plate 12 relative to the conveyor line 2 in the third direction Z is achieved by the relative movement of the sliders and the guide rails.
[0074] In some embodiments, the first plate 11 and the second plate 12 are detachably mounted on both sides of the conveyor line 2 along a first direction.
[0075] Specifically, the detachable connection between the first plate 11 and the conveyor line 2 can be achieved through a snap-fit connection or a bolt connection; this embodiment of the application does not impose any limitation on this. Similarly, the detachable connection between the second plate 12 and the conveyor line 2 can also be achieved through a snap-fit connection or a bolt connection.
[0076] By detachably connecting the first plate 11 and the second plate 12 to the conveyor line 2, it is convenient to disassemble the storage device 1 and move it to other locations, which facilitates the centralized storage of the collected solar cell silicon wafers 4 and the transfer of the solar cell silicon wafers 4 from one conveyor line to another.
[0077] like Figure 4 and Figure 5 As shown, in some embodiments, the solar cell manufacturing equipment further includes a frame 3 extending along a third direction Z, with the first plate 11 and the second plate 12 movably disposed on the frame along the third direction Z.
[0078] Specifically, a guide rail extending in the third direction Z can be installed on one of the first plate 11 and the frame 3, and a slider can be installed on the other. The relative movement of the guide rail and the slider realizes the movement of the first plate 11 relative to the frame 3, and thus the movement of the first plate 11 relative to the conveyor line 2. The relative movement between the second plate 12 and the frame 3 is set in the same way, and will not be described in detail here.
[0079] Specifically, such as Figures 1 to 5 As shown, when storing solar cell silicon wafers, the first plate 11 and the second plate 12 move upward along the third direction Z, causing the solar cell silicon wafer 4 located in the storage section 13 to abut against the first protrusion 111 and the second protrusion 121. This then drives the solar cell silicon wafers in the storage section 13 to move upward, thereby carrying the solar cell silicon wafer 4 from the conveyor line 2 away from the conveyor line 2 and storing it in the storage device 1. Similarly, the next solar cell silicon wafer 4 on the conveyor line 2 is stored in the storage section 13 of the next layer, completing the sequential storage of the solar cell silicon wafers 4 on the conveyor line 2.
[0080] After storage, if it is necessary to move the solar cell silicon wafer 4, simply disassemble the storage device 1 and grasp the holding part 16 to easily move the solar cell silicon wafer 4.
[0081] When it is necessary to release the solar cell silicon wafer 4, the first plate 11 and the second plate 12 move downward along the third direction Z, causing the solar cell silicon wafer located in the storage section 13 to move downward. When it descends to a certain height, the conveying plane 21 of the solar cell silicon wafer 4 conveying line 2 contacts and disengages from the first protrusion 111 and the second protrusion 121, so that the solar cell silicon wafer 4 is placed back on the conveying line 2 and released from the storage device 1 under the conveying of the conveying line 2. Similarly, the next solar cell silicon wafer 4 stored in the storage section 13 of the upper layer of the storage device 1 is then placed back on the conveying line 2, completing the sequential release of the solar cell silicon wafers 4 in the storage device 1.
