Description

Technical Field

[0001] This application relates to the field of solar cell production equipment technology, and in particular to switching devices and solar cell flipping devices. Background Technology

[0002] With the continuous innovation of HJT (heterojunction) solar cell manufacturing technology, the cell production process is constantly being optimized. In the screen printing process of solar cells, grid lines need to be printed on both sides of the cell, thus requiring a corresponding flipping device to flip the cells. The flipping device typically has two operating modes: when the cells do not need to be flipped, the reserved channel of the flipping device remains open, and the cells can be directly conveyed through the reserved channel; when flipping is required, the reserved channel of the flipping device must be blocked so that the flipping device can still drive the cells to flip.

[0003] In related technologies, when flipping is required, a block is typically installed at the reserved channel of the flipping equipment to block the direct path. This switches to flipping mode, allowing the solar cells to enter the flipping process. However, switching flipping modes requires frequent removal or installation of the block, which is cumbersome and time-consuming. Furthermore, when the surrounding space of the flipping equipment is limited, removing and installing the block is inconvenient, leading to high operational difficulty, inconvenient flipping mode switching, and low switching efficiency. Utility Model Content

[0009] A transmission mechanism is connected to both the mounting base and the switching mechanism. The transmission mechanism is configured to drive the switching mechanism to move relative to the mounting base under the action of an external force, so that the switching mechanism switches between the retracted state and the limited state.

[0014] In one embodiment, the switching device further includes a second guide mechanism, which includes a second guide rail and a second slider. The second guide rail is connected to the mounting base, and the second slider is slidably connected to the second guide rail.

[0015] The switching mechanism is movably connected to the second slider.

[0016] In one embodiment, the extension direction of the second guide rail is parallel to the extension direction of the first guide rail.

[0020] In one embodiment, the locking component includes a housing, a first locking member, and a second locking member, wherein the first locking member and the second locking member are elastically connected to the housing, and a locking gap is provided between the first locking member and the second locking member;

[0021] The movable component includes a movable body and a movable locking head. The movable body is connected to the first slider, and the movable locking head is connected to the movable body to form a locking groove. The movable locking head is configured to press the first locking member and the second locking member and pass through the locking gap under the action of external force.

[0027] The aforementioned switching device and cell flipping device include a switching mechanism. When the switching mechanism of the switching device needs to switch to a limited position, an external force is applied to the transmission mechanism to drive the switching mechanism to move, causing the switching mechanism to protrude outside the mounting area of ​​the mounting base and extend into the reserved channel of the cell flipping device. At this time, the switching mechanism can block and limit the cell, allowing the cell flipping device to perform the cell flipping operation. When the switching mechanism needs to switch to a retracted position, an external force is applied to the transmission mechanism to drive the switching mechanism to move, causing the switching mechanism to retract within the mounting area of ​​the mounting base and withdraw from the reserved channel of the cell flipping device. At this time, the switching mechanism releases the blocking and limiting of the cell, allowing the cell to pass through the reserved channel of the flipping device. Thus, the switching device of this embodiment can achieve mode switching through the cooperation of the transmission mechanism and the switching mechanism, making the switching operation of the cell flipping device more convenient and faster, improving switching efficiency, and reducing the workload of operators. Furthermore, since the switching process does not require complex installation and disassembly operations, the switching device can achieve rapid switching operations even in confined spaces, avoiding operational inconvenience caused by limited space.

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] See Figure 1As shown, an embodiment of this application provides a battery cell flipping device 1, which includes a switching device 10. This device can be installed at a suitable location on a battery cell screen printing production line. Because of the switching device 10, when the battery cell does not need to be flipped, the switching device 10 is in a retracted state, allowing the battery cell to pass smoothly through the reserved channel 11 of the battery cell flipping device 1 and enter subsequent processes. When the battery cell needs to be flipped, the switching device 10 is operated to switch to a limit state, blocking the reserved channel 11 of the battery cell flipping device 1. At this time, the battery cell is flipped under the action of the battery cell flipping device 1. Therefore, the battery cell flipping device 1 in this embodiment, based on the rapid switching function of the switching device 10, can quickly switch the working mode of the battery cell flipping device 1, reducing the workload of the flipping operator and improving the flipping efficiency. Simultaneously, the stability and reliability of the switching device 10 ensure that the battery cell flipping device 1 can operate accurately in different working modes, helping to improve the production quality and efficiency of the battery cells, reduce production costs, and increase production capacity.

[0052] See Figures 2 to 4 As shown, a schematic diagram of the switching device 10 in one embodiment of this application is shown. The switching device 10 provided in one embodiment of this application includes a mounting base 100, a movable mechanism 200, a switching mechanism 300 and a transmission mechanism 400. The switching device 10 can quickly switch between the retracted state and the limiting state, thereby improving the efficiency of the switching operation.

[0053] The mounting base 100 serves as the mounting foundation for the switching device 10 and can be installed on the cell flipping device 1. One side of the mounting base 100 has a mounting area for mounting other components. For example, the mounting base 100 can be a metal plate with a certain thickness and strength, with a flat mounting area on one side. This mounting area can be the area enclosed by the boundary of the side of the mounting base 100, ensuring that other components located within the mounting area do not obstruct the reserved channel 11 of the cell flipping device 1. Of course, in other optional embodiments, the mounting base 100 can also be a partial structure of the cell flipping device 1 itself, that is, other components such as the switching mechanism 300 can be directly mounted on the cell flipping device 1.

[0054] The movable mechanism 200 is used to connect the switching mechanism 300 and the mounting base 100, and the movable mechanism 200 is movably connected to the mounting base 100. For example, the movable mechanism 200 can be a long, rod-shaped structure, and its end is configured to rotate around a fixed point on the mounting base 100, for example, through a pin or bearing to achieve a rotatable connection with the mounting base 100, so that the movable mechanism 200 can flexibly rotate within a certain angle range, easily adapting to different angle changes that may occur during the movement of the switching mechanism 300.

[0055] The switching mechanism 300 is movably connected to the movable mechanism 200 and, through the movable mechanism 200, to the mounting base 100. The switching mechanism 300 is used to switch the operating mode of the cell flipping device 1. The switching mechanism 300 has a retracted state and a limiting state. The switching mechanism 300 is configured to retract within the mounting area in the retracted state and protrude outside the mounting area in the limiting state. Specifically, after the mounting base 100 is mounted on the cell flipping device 1, force is applied to the switching mechanism 300 to make it protrude outside the mounting area of ​​the mounting base 100, so that the switching mechanism 300 extends into the reserved channel 11 of the cell flipping device 1. Thus, the switching mechanism 300 can be used to block and limit the cell flipping, preventing the cell from passing through the reserved channel 11, so that the cell flipping device 1 can perform the cell flipping operation. When the solar cells do not need to be flipped, force is applied to the switching mechanism 300 to retract it within the installation area, so that the switching mechanism 300 is withdrawn from the reserved channel 11 of the solar cell flipping device 1. At this time, the solar cells can pass smoothly through the reserved channel 11.

[0056] The transmission mechanism 400 is connected to both the mounting base 100 and the switching mechanism 300, and is used to drive the switching mechanism 300 to move relative to the mounting base 100. Specifically, the transmission mechanism 400 is movably connected to both the mounting base 100 and the switching mechanism 300, such that the switching mechanism 300 is connected to the mounting base 100 both through the movable mechanism 200 and through the transmission mechanism 400, so that the switching mechanism 300 and the mounting base 100 are securely connected. The transmission mechanism 400 is configured to drive the switching mechanism 300 to move relative to the mounting base 100 under the action of an external force, so that the switching mechanism 300 switches between a retracted state and a limited state. This external force can be applied to the transmission mechanism 400 by an operator, or driven by a separate drive component such as a motor.

[0057] Through the above structural design, when the switching mechanism 300 needs to switch to the limit state, an external force is applied to the transmission mechanism 400 to drive the switching mechanism 300 to move, causing the switching mechanism 300 to protrude beyond the mounting area of ​​the mounting base 100 and extend into the reserved channel 11 of the battery cell flipping device 1. At this time, the switching mechanism 300 can block and limit the battery cell, so that the battery cell flipping device 1 can perform the flipping operation on the battery cell. When the switching mechanism 300 needs to switch to the retracted state, an external force is applied to the transmission mechanism 400 to drive the switching mechanism 300 to move, causing the switching mechanism 300 to retract within the mounting area of ​​the mounting base 100 and withdraw from the reserved channel 11 of the battery cell flipping device 1. At this time, the switching mechanism 300 releases the blocking and limiting of the battery cell, so that the battery cell can pass through the reserved channel 11 of the flipping device. Thus, the switching device 10 of this embodiment can realize mode switching through the cooperation of the transmission mechanism 400 and the switching mechanism 300, making the switching operation of the battery cell flipping device 1 more convenient and faster, improving the switching efficiency, and reducing the workload of the operator. Furthermore, since the switching process does not require complex installation and disassembly operations, the switching device 10 can achieve rapid switching operations even in confined spaces, avoiding operational inconvenience caused by limited space.

[0058] See Figure 4As shown, in some embodiments, the switching mechanism 300 includes a switching component 310, which includes a first connecting segment 311, a second connecting segment 312, and a limiting segment 313 connected in sequence, with the first connecting segment 311, the second connecting segment 312, and the limiting segment 313 distributed along a straight line. One end of the first connecting segment 311 is movably connected to the movable mechanism 200, and the other end of the first connecting segment 311 is connected to the second connecting segment 312. The second connecting segment 312 is movably connected to the transmission mechanism 400, and the limiting segment 313 is connected to the end of the second connecting segment 312 away from the first connecting segment 311. The limiting segment 313 is configured to retract into the installation area in a retracted state and protrude outside the installation area in a limited state. When the switching mechanism 300 needs to switch to the limit state, a pushing force is applied to the second connecting section 312 via the transmission mechanism 400. Since the first connecting section 311 is movably connected to the mounting base 100 via the movable mechanism 200, the second connecting section 312, under the action of this pushing force, will cause the limit section 313 to protrude outside the mounting area of ​​the mounting base 100, thereby blocking the battery cell to ensure that the battery cell enters the flipping process. When the switching mechanism 300 needs to switch to the retracted state, a pulling force is applied to the second connecting section 312 via the transmission mechanism 400. Under the action of this pulling force, the second connecting section 312 will cause the limit section 313 to retract within the mounting area of ​​the mounting base 100, thereby releasing the blocking and limiting of the battery cell. Therefore, by cooperating with the moving mechanism 200 and the transmission mechanism 400 respectively through the first connecting section 311, the second connecting section 312 and the limiting section 313, the limiting section 313 can be driven to accurately switch between the contracted state and the limiting state, making the operation of the switching mechanism 300 more stable and reliable, and improving the accuracy and stability of the cell flipping operation.

[0059] Furthermore, in some embodiments, the first connecting segment 311 is rotatably connected to the movable mechanism 200 via a first rotating shaft, allowing the first connecting segment 311 to rotate freely around the first rotating shaft. The second connecting segment 312 is rotatably connected to the transmission mechanism 400 via a second rotating shaft, allowing the second connecting segment 312 to rotate freely around the second rotating shaft. The first rotating shaft and the second rotating shaft are parallel and perpendicular to the side of the mounting base 100. When the switching component 310 is driven to move by the transmission mechanism 400, the second rotating shaft constrains the second connecting segment 312 to rotate relative to the transmission mechanism 400, while the first rotating shaft constrains the first connecting segment 311 to rotate relative to the movable mechanism 200. Since the first rotating shaft and the second rotating shaft are arranged parallel, the movement trajectory of the switching component 310 is limited to the same plane as much as possible, which can avoid the movement deviation of the limiting segment 313 caused by the misalignment of the first rotating shaft and the second rotating shaft, ensuring that the limiting segment 313 can accurately block and limit the battery cell, and improving the reliability of mode switching.

[0060] See Figure 2 and Figure 4 As shown, in some embodiments, the switching device 10 further includes a first guide mechanism 500, which includes a first guide rail 510 and a first slider 520. The first guide rail 510 is connected to the mounting base 100, and the first slider 520 is slidably connected to the first guide rail 510. One end of the transmission mechanism 400 is rotatably connected to the first slider 520, and the other end of the transmission mechanism 400 is rotatably connected to the switching mechanism 300. When the transmission mechanism 400 drives the switching mechanism 300 to move under the action of an external force, since the first slider 520 can only slide along the first guide rail 510, the transmission mechanism 400 will be constrained by the first guide rail 510 while driving the switching mechanism 300 to move, ensuring that the switching mechanism 300 can only move along a specific path, effectively improving the accuracy and stability of the movement of the switching mechanism 300, and ensuring that the switching mechanism 300 can accurately switch between the contracted state and the limited state.

[0061] Optionally, see Figure 3 As shown, in some embodiments, the switching device 10 further includes a second guide mechanism 600, which includes a second guide rail 610 and a second slider 620. The second guide rail 610 is connected to the mounting base 100, the second slider 620 is slidably connected to the second guide rail 610, and the switching mechanism 300 is movably connected to the second slider 620. Thus, during the movement of the switching mechanism 300, the first guide mechanism 500 and the second guide mechanism 600 function simultaneously. The first guide mechanism 500 ensures the accuracy of the path when the transmission mechanism 400 drives the switching mechanism 300, while the second guide mechanism 600 further guides and supports the switching mechanism 300, making the switching mechanism 300 move more smoothly and the switching action more stable and reliable.

[0062] Furthermore, in some embodiments, the extension direction of the second guide rail 610 is parallel to the extension direction of the first guide rail 510, so that the guiding force received by the switching mechanism 300 during the movement is more uniform, and there will be no problems such as uneven force or jamming caused by non-parallel guide rails. This ensures that the switching mechanism 300 can switch more smoothly between the contracted state and the limited state under the combined action of the first guide mechanism 500 and the second guide mechanism 600.

[0063] See Figure 3 , Figures 5 to 7As shown, in some embodiments, the switching device 10 further includes a locking mechanism 700, which includes a locking component 710 and a movable component 720. The locking component 710 is connected to the mounting base 100, for example, by bolts to fix the locking component 710 to the mounting base 100. The movable component 720 is connected to the first slider 520, and the movable component 720 and the first slider 520 do not move relative to each other. The movable component 720 is configured to move under the action of an external force to engage with the locking component 710 to lock the first slider 520. When the switching mechanism 300 moves to the desired retracted state or limit state, the movable component 720 is moved by an external force, and the movable component 720 moves toward the locking component 710 until it engages with the locking component 710, thereby locking the first slider 520 in the current position and ensuring that the switching mechanism 300 is stably maintained in the current state. Therefore, the locking mechanism 700 can effectively prevent the first slider 520 from moving due to vibration and other factors, ensuring that the switching mechanism 300 works stably in the set state, and enhancing the stability and reliability of the switching device 10.

[0064] It should be noted that when the mounting base 100 adopts part of the structure of the battery cell flipping device 1 itself, such as using the outer shell of the battery cell flipping device 1 as the mounting base 100, the switching mechanism 300 and other components can be placed inside the outer shell of the battery cell flipping device 1, while the locking mechanism 700 can be placed outside the outer shell of the battery cell flipping device 1. In this way, the operator can perform the switching operation outside the outer shell of the battery cell flipping device 1.

[0065] Specifically, in some embodiments, the first slider 520 and the switching mechanism 300 are disposed on the inner side of the mounting base 100, and the locking member 710 is connected to the side of the mounting base 100 opposite to the first slider 520, that is, the locking member 710 is disposed on the outer side of the mounting base 100. A guide groove 110 is provided through the mounting base 100, the shape and size of which match the movable member 720, thereby providing motion guidance for the movable member 720 and preventing it from deviating from its trajectory due to external interference during movement. One end of the movable member 720 is connected to the first slider 520 located inside the mounting base 100, and the other end of the movable member 720 passes through the guide groove 110 for engagement with the locking member 710 located on the outer side of the mounting base 100. By setting the switching mechanism 300 and the locking component 710 on opposite sides of the mounting base 100, and extending the two ends of the movable component 720 to the inner and outer sides of the mounting base 100 respectively, the operator can apply force to the outer side of the mounting base 100 to drive the movable component 720 to move, thereby driving the first slider 520 on the inner side of the mounting base 100, and then driving the switching mechanism 300 to perform corresponding movements, making the switching operation more convenient.

[0066] Optionally, see Figure 6 and Figure 7 As shown, in some embodiments, the locking component 710 includes a housing 711, a first locking member 712, and a second locking member 713. The first locking member 712 and the second locking member 713 are elastically connected to the housing 711, and a locking gap exists between them. Exemplarily, one end of the first locking member 712 is elastically connected to the housing 711 via a first elastic member 714, and the other end of the first locking member 712 is disposed opposite to the second locking member 713. One end of the second locking member 713 is elastically connected to the housing 711 via a second elastic member 715, and the other end of the second locking member 713 is disposed opposite to the first locking member 712. Both the first elastic member 714 and the second elastic member 715 can be springs. In their natural state, a certain locking gap is maintained between the first locking member 712 and the second locking member 713.

[0067] The movable component 720 includes a movable body 721 and a movable locking head 722. The movable body 721 is connected to the first slider 520, and the movable locking head 722 is connected to the movable body 721 to form a locking groove 723. The movable locking head 722 is configured to press the first locking member 712 and the second locking member 713 and pass through the locking gap under the action of external force. The first locking member 712 and the second locking member 713 are configured to reset and insert into the locking groove 723 under the action of elastic force. Exemplarily, one side of the movable locking head 722 is provided with a spherical surface, and the first locking member 712 and the second locking member 713 are provided with corresponding inclined surfaces. This can reduce the friction between the movable locking head 722 and the first locking member 712 and the second locking member 713, so that the movable locking head 722 can quickly pass through the locking gap.

[0068] When it is necessary to lock the movable part 720, push the movable part 720 to cause the movable lock head 722 to press against the first locking member 712 and the second locking member 713. At this time, the first locking member 712 and the second locking member 713 overcome the elastic force and open to both sides, and the movable lock head 722 passes through the locking gap. Afterwards, the first locking member 712 and the second locking member 713 reset under the action of the elastic force and insert into the locking groove 723, thereby locking the movable part 720 and the first slider 520. When it is necessary to unlock, by moving the first locking member 712 and the second locking member 713, the first locking member 712 and the second locking member 713 are opened to both sides. At this time, the movable part 720 can be removed, thereby unlocking the movable part 720 and the first slider 520. Thus, by elastically connecting the first locking member 712 and the second locking member 713 to the housing 711 respectively, the locking and unlocking functions can be conveniently realized, and a high locking strength can be maintained to ensure that the switching mechanism 300 is stably maintained in the required state.
