Description

Technical Field

[0001] This application relates to the field of photovoltaic module manufacturing technology, and in particular to a feeding box and photovoltaic module manufacturing equipment. Background Technology

[0002] In the photovoltaic industry, the supply chain can be divided into upstream and downstream components: silicon, metallic silicon, polycrystalline silicon, silicon rods, silicon wafers, solar cells, modules, arrays, and power station systems. Power station systems consist of photovoltaic modules, foundations, supports, combiner boxes, inverters, transformer substations, and finally, the power grid. Individual solar cells, due to their fragility and poor aging resistance, cannot be used directly as power sources; they need to be welded, connected in series and parallel, and tightly sealed into modules for long-term use. Solar cell modules (photovoltaic modules) are the core and most important part of a solar power generation system. Their function is to convert solar energy into electrical energy, which can be stored in batteries in off-grid systems, connected to loads, or connected to the grid.

[0003] The module manufacturing process includes string welding, layout, stacking, lamination, glass bonding, EL appearance inspection, edge sealing, lamination, edge trimming, flipping inspection, frame assembly, junction box assembly, potting, curing, cleaning, IV testing, insulation withstand voltage testing, EL testing, FQC appearance inspection, grading, and packaging. To ensure photovoltaic modules meet customer requirements, accurately identify faulty equipment, and achieve complete material traceability, it is necessary to link the production information of the solar cells with the photovoltaic module.

[0004] With the development of solar cell technology, the size of solar cells is gradually increasing, and the number of loading boxes required for different sizes is also gradually increasing. This increases the production cost of photovoltaic modules. Furthermore, the need to change the loading box according to the size of the solar cell during production increases the complexity of the process. Currently, to enable the loading box to adapt to solar cells of different sizes, sliding or removable baffles are usually installed on the loading box, allowing adjustment of the box's size. However, currently, each baffle is independently configured. Adjusting the position of each baffle according to the size of the solar cell requires independent adjustment of each baffle, which is time-consuming and affects adjustment and production efficiency. Utility Model Content

[0005] Therefore, it is necessary to address the problem of low adjustment efficiency and production efficiency caused by the independent adjustment of the baffle of the feeding box in the current photovoltaic module production, and to provide a feeding box and photovoltaic module production equipment that can carry solar cells of different sizes and can ensure adjustment efficiency and production efficiency.

[0006] A loading box for holding battery cells, the loading box comprising:

[0007] The support structure includes a support base and a support cover disposed on the support base, the support cover having a through adjustment hole;

[0008] Multiple sets of blocking components extending along the height direction, one end of each blocking component located on the support base, and the other end extending through the adjustment hole, are spaced apart circumferentially and together with the support cover to form a receiving space for accommodating the battery cell; and

[0014] In one embodiment of this application, the first transmission structure includes two sets of moving components and a connecting component. The two sets of moving components are spaced apart along the axial direction and are connected by the connecting component. The output ends of the two sets of moving components are respectively connected to the first blocking component and the third blocking component. When one set of moving components moves, it can drive the other set of moving components to rotate synchronously through the connecting component, so that the first blocking component and the third blocking component move closer to each other or further away from each other.

[0015] And / or, the second transmission structure includes a transmission component and two output components. The two output components are respectively connected to the transmission component and output opposite movements.

[0018] And / or, both the first transmission structure and the second transmission structure further include an adjustment knob, which is disposed at the end of the moving component and the transmission component, and the adjustment knob can drive the moving component and the transmission component to rotate;

[0019] And / or, the support base has multiple fixing parts, and each of the moving component and the transmission component has at least one fixing part corresponding to each end, and the fixing part is rotatably capable of supporting the moving component and the transmission component.

[0022] In one embodiment of this application, the blocking component includes opposing stop bars and a connecting portion connecting the two stop bars, the connecting portion being tractively connected to the transmission structure, and the stop bars extending through the adjustment hole;

[0023] Alternatively, the blocking component includes a baffle and a support portion disposed at one end of the baffle, the support portion being tractively connected to the transmission structure, and the baffle extending through the adjustment hole.

[0024] In one embodiment of this application, the feeding box further includes an RFID device and a locking structure, the support base includes a mounting base and a mounting plate, the RFID device is disposed on the mounting base, and the mounting plate covers the mounting base;

[0025] The locking structure is disposed on the mounting base and can engage the mounting plate to lock the mounting plate to the mounting base.

[0026] In one embodiment of this application, the locking structure includes a pusher, a pull rod, an elastic element, a linkage group, and a locking element. The pusher is movably disposed on the linkage group along the height direction. The linkage group is throttle-connected to the locking element and disposed on the pull rod. The pull rod is disposed on the mounting base. The locking element is slidably disposed on the mounting base. The elastic element is sleeved on the pull rod, and its two ends abut against the pull rod and the locking element.

[0027] The elastic force of the elastic element can push the locking element to engage with the mounting plate, and the pressing force of the pressing component can drive the locking element to compress the elastic element through the linkage assembly, so that the locking element disengages from the mounting plate.

[0028] A photovoltaic module manufacturing equipment includes a conveyor line, a welding device, and a feeding box as described in any of the above technical features;

[0029] The feeding box carries battery cells of the corresponding size. The welding device is located on the side of the conveyor line and is used to weld the battery cells into battery strings.

[0030] By adopting the above technical solution, this application has at least the following technical effects:

[0031] The feeding box and photovoltaic module production equipment of this application include a feeding box in which multiple sets of blocking components are spaced apart circumferentially and extend along the height direction. One end of each blocking component is located between a support base and a support cover, and the other end extends through the top of the support cover. The multiple sets of blocking components and the support cover enclose a receiving space to accommodate solar cells. Furthermore, a transmission structure is disposed between the support base and the support cover and is drively connected to at least two sets of blocking components. In this way, the transmission structure can drive the blocking components to move closer or further apart to adjust the size of the receiving space.

[0032] This feeding box uses a transmission structure to move blocking components, allowing at least two sets of blocking components to move inwards or outwards towards the receiving space. This reduces or increases the size of the receiving space, thus adjusting the size of the feeding box. This allows the feeding box to accommodate solar cells of different sizes, eliminating the need for multiple feeding boxes of different specifications, reducing production costs and complexity. Simultaneously, the transmission structure enables the synchronous movement of at least two sets of blocking components, simplifying the adjustment process, improving the efficiency of feeding box size adjustment, and ultimately increasing the production efficiency of photovoltaic modules.

[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] The module manufacturing process includes string welding, layout, stacking, lamination, glass bonding, EL appearance inspection, edge sealing, lamination, edge trimming, flipping inspection, frame assembly, junction box assembly, potting, curing, cleaning, IV testing, insulation withstand voltage testing, EL testing, FQC appearance inspection, grading, and packaging. To ensure photovoltaic modules meet customer requirements, accurately identify faulty equipment, and achieve complete material traceability, it is necessary to link the production information of the solar cells with the photovoltaic module.

[0052] Typically, solar cells are transported to the unpacking room, where they are unpacked manually. The box number and individual package number of the solar cells are scanned and linked to RFID (Radio Frequency Identification) for feeding. The binding information is then uploaded to the MES (Manufacturing Execution System). When the solar cell loading box is transported to the scribing and welding machine, the equipment reads the RFID chip with the feeding information and uploads the feeding information to the MES system. Through the equipment system, the production of solar cells is linked to various devices, thereby enabling the traceability of solar cell information for photovoltaic modules.

[0053] With the development of solar cell technology, the size of solar cells is gradually increasing, and the number of loading boxes required for different sizes is also gradually increasing. This increases the production cost of photovoltaic modules. Furthermore, the need to change the loading box according to the size of the solar cell during production increases the complexity of the process. Currently, to enable the loading box to adapt to solar cells of different sizes, sliding or removable baffles are usually installed on the loading box, allowing adjustment of the box's size. However, currently, each baffle is independently configured. Adjusting the position of each baffle according to the size of the solar cell requires independent adjustment of each baffle, which is time-consuming and affects adjustment and production efficiency.

[0054] For this reason, see Figure 1 and Figure 2 This application provides a feeding box 100. Figure 1 This is a perspective view of a feeding box 100 according to an embodiment of this application. Figure 2 for Figure 1 The diagram shows an exploded view of the loading box 100. This loading box 100 is primarily used to hold solar cells (not shown), facilitating cell loading. Of course, in other embodiments of this application, the loading box 100 can also hold other cell structures required in the production process. This application only describes the loading box 100 holding solar cells as an example. Furthermore, this loading box 100 can be applied in photovoltaic module production equipment to achieve cell loading.

[0055] In this application, the size of the loading box 100 is adjustable, enabling it to accommodate solar cells of different sizes. This eliminates the need for multiple loading boxes 100 of different specifications, reducing production costs and complexity. Furthermore, the size adjustment process for the loading box 100 is simple, improving its adjustment efficiency and consequently increasing the production efficiency of photovoltaic modules.

[0056] See Figures 1 to 5In one embodiment, the feeding box 100 includes a support structure 110, multiple sets of blocking components 120, and at least one transmission structure 130. The support structure 110 includes a support base 111 and a support cover 112 covering the support base 111, the support cover 112 having a through adjustment hole 1121. The multiple sets of blocking components 120 extend along the height direction, one end of the blocking component 120 is located on the support base 111, and the other end extends out through the adjustment hole 1121. The multiple sets of blocking components 120 are circumferentially spaced and together with the support cover 112 form a receiving space 101 for receiving battery cells.

[0057] At least one transmission structure 130 is disposed between the support base 111 and the support cover 112, and is connected to at least two sets of blocking components 120. The transmission structure 130 can drive the at least two sets of blocking components 120 to move closer or further away from each other in order to adjust the size of the accommodating space 101. Figure 3 for Figure 2 The figure shows a perspective view of the support base 111 in the feeding box 100, which supports the transmission structure 130 and the blocking component 120. Figure 4 for Figure 3 The top view shown is of the support base 111 supporting the transmission structure 130 and the blocking component 120. Figure 5 for Figure 3 The side view shown shows the support base 111 supporting the transmission structure 130 and the blocking component 120.

[0058] The support structure 110 serves as a housing for supporting and protecting the feeding box 100. The transmission structure 130 is movably disposed within the support structure 110, and the blocking member 120 can extend through the support structure 110. In this way, the support structure 110 can carry the battery cells, and the blocking member 120 blocks and limits the battery cells to ensure that their position is fixed, facilitating the feeding of the battery cells.

[0059] Specifically, the support structure 110 includes a support base 111 and a support cover 112. The support cover 112 covers the support base 111 and together with the support base 111, forms a hollow mounting cavity. The support cover 112 has an adjustment hole 1121 that extends into the mounting cavity. The transmission structure 130 is movably disposed in the mounting cavity. The blocking member 120 extends along the height direction. The bottom end of the blocking member 120 is located in the mounting cavity and is connected to the transmission structure 130. The top end of the blocking member 120 extends through the adjustment hole 1121 of the support cover 112.

[0060] like Figure 1 and Figure 2As shown, the vertical and top-bottom directions of the blocking component 120 are the same as the height direction of the blocking component 120, and this height direction is also the height direction of the feeding box 100. It also applies to other components of the feeding box 100, which will not be repeated hereafter. In this application, there are multiple sets of blocking components 120, and the multiple sets of blocking components 120 are arranged at intervals along the circumference of the support structure 110. Here, the circumference refers to the circumferential direction of the outer circle of the support structure 110, and this circumferential direction also applies to other components of the feeding box 100.

[0061] After multiple sets of blocking components 120 are arranged at circumferential intervals, there is a gap between adjacent sets of blocking components 120. In addition, the blocking components 120 extend along the height direction. At this time, the multiple sets of blocking components 120 and the supporting cover 112 can form a receiving space 101. The supporting cover 112 is equivalent to the bottom plate of the receiving space 101, and the multiple sets of blocking components 120 are equivalent to the blocking components on the side walls of the receiving space 101. The bottommost battery cell is in contact with the lower surface of the supporting cover 112, and the remaining battery cells are stacked in sequence in the receiving space 101. Furthermore, the edges of the battery cells are limited by the multiple sets of blocking components 120, so that the feeding box 100 can carry the battery cells and limit their position. During the feeding process, the position of the battery cells may shift, affecting the quality of the battery cells.

[0062] Furthermore, to enable the loading box 100 to accommodate battery cells of different sizes, this application also provides at least one transmission structure 130 between the support base 111 and the support cover 112. The at least one transmission structure 130 can drive at least two sets of blocking components 120. When the transmission structure 130 moves, it can drive at least two sets of blocking components 120 to move synchronously, so that the at least two sets of blocking components 120 can move towards the inside or outside of the receiving space 101 at the same time, thereby bringing the at least two sets of blocking components 120 closer to or further away from each other, thereby adjusting the size of the receiving space 101.

[0063] When the transmission structure 130 drives at least two sets of blocking components 120 to move toward the inside of the receiving space 101, the at least two sets of blocking components 120 move closer to each other, and the distance between each set of blocking components 120 decreases, that is, the size of the receiving space 101 becomes smaller, thereby realizing the adjustment of the size of the feeding box 100 to become smaller. At this time, the receiving space 101 in the feeding box 100 can carry smaller-sized battery cells.

[0064] Similarly, when the transmission structure 130 drives at least two sets of blocking components 120 to move toward the outside of the receiving space 101, the at least two sets of blocking components 120 move away from each other, and the distance between each set of blocking components 120 increases, that is, the size of the receiving space 101 becomes larger, thereby realizing the adjustment of the size of the feeding box 100 to become larger. At this time, the receiving space 101 in the feeding box 100 can carry larger-sized battery cells.

[0065] This application uses a transmission structure 130 to adjust the position of each group of blocking components 120, so that the feeding box 100 can carry battery cells of different sizes. In this way, a single type of feeding box 100 can carry battery cells of different sizes, eliminating the need for multiple specifications of feeding boxes 100, reducing production costs. At the same time, there is no need to change the feeding box 100 during production, reducing the complexity of production.

[0066] Meanwhile, this application achieves the adjustment of the size of the feeding box 100 and the correlation between the blocking components 120 by driving at least two sets of blocking components 120 to move synchronously through at least one transmission structure 130. When one blocking component 120 is adjusted, at least the other blocking component 120 also moves synchronously, without the need to adjust the position of the blocking component 120 separately, simplifying the adjustment process of the blocking component 120, improving the adjustment efficiency of the size of the feeding box 100, and thus improving the production efficiency of photovoltaic modules.

[0067] See Figures 2 to 5 In one embodiment of this application, each transmission structure 130 connects to two opposing sets of blocking members 120, so that the opposing sets of blocking members 120 move closer to or further away from each other. That is, there are at least two transmission structures 130 and at least four sets of blocking members 120, with each transmission structure 130 drivingly connecting to two opposing sets of blocking members 120. In this way, when the transmission structure 130 moves, it can simultaneously drive the two opposing sets of blocking members 120 to move, so that the opposing sets of blocking members 120 move closer to or further away from each other.

[0068] Understandably, the battery cells are rectangular or square in shape. This application uses a transmission structure 130 to adjust the distance between two sets of blocking components 120. At least two transmission structures 130 drive the corresponding two sets of blocking components 120 to move the same or different distances. During adjustment, one transmission structure 130 drives the corresponding two sets of blocking components 120 to move a corresponding distance, and the other transmission structure 130 drives the corresponding two sets of blocking components 120 to move a corresponding distance, so that the feeding box 100 can carry square or rectangular battery cells.

[0069] In another embodiment of this application, a transmission structure 130 simultaneously drives and connects each group of blocking components 120, causing each group of blocking components 120 to move simultaneously toward the inside or outside of the receiving space 101. That is, the blocking components 120 move synchronously. At this time, the transmission structure 130 can drive multiple groups of blocking components 120 to move synchronously through bevel gear transmission or other means, and the movement distance between each group of blocking components 120 is the same, so that the feeding box 100 can carry the square battery cell.

[0070] It is worth noting that the structure and motion principle of driving each set of blocking components 120 through a transmission structure 130 are essentially the same as the structure and motion principle of driving two sets of transmission components through a transmission structure 130. The difference lies in the design of the number of bevel gear transmissions. This application will only use the example of driving two sets of transmission components through a transmission structure 130 for illustration.

[0071] Furthermore, in this application, the number of blocking components 120 is four sets, namely, the blocking components 120 include a first blocking component 121, a second blocking component 122, a third blocking component 123, and a fourth blocking component 124 arranged circumferentially. Correspondingly, two transmission structures 130 are provided, namely, the first transmission structure 103 and the second transmission structure 104, to drive the four sets of blocking components 120. Of course, in other embodiments of this application, the number of blocking components 120 may be more, and the number of transmission structures 130 may be adjusted according to the number of blocking components 120, as long as there is no interference between their movements.

[0072] See Figures 2 to 5 In one embodiment, the plurality of blocking components 120 include at least a first blocking component 121, a second blocking component 122, a third blocking component 123, and a fourth blocking component 124 arranged circumferentially. At least one transmission structure 130 includes a first transmission structure 103 and a second transmission structure 104, wherein the first transmission structure 103 is drivingly connected to the first blocking component 121 and the third blocking component 123, and the second transmission structure 104 is drivingly connected to the second blocking component 122 and the fourth blocking component 124.

[0073] like Figures 2 to 5 As shown, the first blocking component 121, the second blocking component 122, the third blocking component 123, and the fourth blocking component 124 are arranged at circumferential intervals, and the first blocking component 121 and the third blocking component 123 are arranged opposite to each other, and the second blocking component 122 and the fourth blocking component 124 are arranged opposite to each other. The first transmission structure 103 drives the first blocking component 121 and the third blocking component 123, and the second transmission structure 104 drives the second blocking component 122 and the fourth blocking component 124.

[0074] When the first transmission structure 103 moves, it can drive the first blocking component 121 and the third blocking component 123 to move synchronously, causing them to move closer or further apart (towards the inside or outside of the accommodating space 101, which will not be mentioned again below), thereby adjusting the distance between them. When the second transmission structure 104 moves, it can drive the second blocking component 122 and the fourth blocking component 124 to move synchronously, causing them to move closer or further apart, thereby adjusting the distance between them.

[0075] Understandably, the distance that the first transmission structure 103 drives the first blocking member 121 and the third blocking member 123 to move, and the distance that the second transmission structure 104 drives the second blocking member 122 and the fourth blocking member 124 to move, may be the same or different. Thus, the distance between the first blocking member 121 and the third blocking member 123 can be the same as or different from the distance between the second blocking member 122 and the fourth blocking member 124, so that the accommodating space 101 can accommodate battery cells of different sizes.

[0076] See Figures 2 to 5 In one embodiment, the first transmission structure 103 includes two sets of moving components (not shown) and a connecting component 132. The two sets of moving components are arranged axially at intervals and are connected by the connecting component 132. The output ends of the two sets of moving components are respectively connected to the first blocking component 121 and the third blocking component 123. When one set of moving components moves, it can drive the other set of moving components to rotate synchronously through the connecting component 132, so that the first blocking component 121 and the third blocking component 123 move closer to each other or move further away from each other.

[0077] Two sets of movable components are spaced apart along the extending directions of the first blocking member 121 and the second blocking member 122. One set of movable components is connected to the first blocking member 121, and the other set is connected to the third blocking member 123. A connecting component 132 is rotatably mounted on the support base 111 and drives the two sets of movable components. Thus, when one set of movable components moves, it can drive the first movable component to move. At the same time, this movable component can drive the other set of movable components to move through the connecting component 132. Consequently, the other set of movable components can drive the third blocking member 123 to move synchronously, so that the first blocking member 121 and the third blocking member 123 move closer to or further away from each other.

[0078] See Figures 2 to 6 , Figure 6 for Figure 3The diagram shows a partial enlarged view at point A of the support base 111 supporting the transmission structure 130 and the blocking component 120. In this embodiment, the moving component is a ball screw component, specifically including a screw shaft 131 and an output nut (not shown). The screw shaft 131 is rotatably mounted on the support base 111, and the output nut is movably mounted on the screw shaft 131 and connected to either the first blocking component 121 or the third blocking component 123. In both sets of moving components, the screw shaft 131 has the same helical direction. When the screw shaft 131 rotates, it can drive the output nut to move along the axial direction of the screw shaft 131, thereby driving the first blocking component 121 or the third blocking component 123 to move synchronously.

[0079] Furthermore, the adapter component 132 is a bevel gear transmission component, specifically including a first bevel gear 1321, a second bevel gear 1322, and a third bevel gear 1323. The first bevel gear 1321 and the second bevel gear 1322 are mounted on the lead screw shafts 131 of the two sets of moving components. The third bevel gear 1323 is rotatably mounted on the support base 111 and meshes with the first bevel gear 1321 and the second bevel gear 1322. When the lead screw shaft 131 in one set of moving components rotates and drives the first blocking component 121 to move, the lead screw shaft 131 can drive the first bevel gear 1321 to rotate. Then, the first bevel gear 1321 drives the second bevel gear 1322 to rotate through the third bevel gear 1323, so that the second bevel gear 1322 drives the lead screw shaft 131 in the other set of moving components to rotate. Then, the lead screw shaft 131 can drive the third blocking component 123 to move, so that the first blocking component 121 and the second blocking component 122 move closer to each other or further away from each other.

[0080] Of course, in other possible implementations of this embodiment, the adapter component 132 can also be a worm gear transmission component. The transmission connection of the lead screw shaft 131 in the two sets of moving components can also be realized through the worm gear and worm, and its principle is essentially the same as that of bevel gear transmission, which will not be described in detail in this application.

[0081] In another embodiment of this application, the moving component and the adapter component 132 are belt drive components or chain drive components. Exemplarily, the moving component includes two pulleys and a synchronous belt sleeved on the two pulleys. The synchronous belt connects to the first blocking member 121 or the third blocking member 123. When one of the pulleys rotates, it can drive the synchronous belt to move around the two pulleys. The synchronous belt can drive the first blocking member 121 or the third blocking member 123 to move synchronously. Furthermore, the adapter component 132 is also a belt drive component. In this case, the belt drive component can drive the pulleys of the two moving components. Of course, the adapter component 132 can also be omitted, and the first blocking member 121 and the third blocking member 123 can be directly driven to move closer or further apart through the belt drive component.

[0082] See Figures 2 to 6In one embodiment, the second transmission structure 104 includes a transmission component 133 and two output components (not shown). The two output components are respectively connected to the transmission component 133 and output opposite movements. The two output components are respectively connected to the second blocking component 122 and the fourth blocking component 124. The transmission component 133 drives the second blocking component 122 and the fourth blocking component 124 to move through the two output components, so that the second blocking component 122 and the fourth blocking component 124 move closer to each other or further away from each other.

[0083] The transmission component 133 is movably mounted on the support base 111. Two output components are connected to the transmission component 133 in a relative transmission manner, so that the two output components can output opposite movements. When the transmission component 133 moves, it can simultaneously drive the two output components to move in opposite directions, and thus the two output components can simultaneously drive the second blocking component 122 and the fourth blocking component 124 to move synchronously, so that the second blocking component 122 and the fourth blocking component 124 move closer to each other or further away from each other.

[0084] See Figures 2 to 6 In one embodiment, the transmission component 133 is a lead screw shaft with two opposite threaded portions, and the two output components are lead screw nuts. The lead screw shaft and the two lead screw nuts form a ball screw component. The transmission component 133 is rotatably disposed on the support base 111 along the line connecting the second blocking component 122 and the fourth blocking component 124, and the two threaded portions on the transmission component 133 have opposite helical directions. When the transmission component 133 rotates, the transmission component 133 can drive the two output components to output opposite movements through the opposite threaded portions, thereby causing the second blocking component 122 and the fourth blocking component 124 to move closer to or further away from each other.

[0085] Of course, in another embodiment of this application, the transmission component 133 is a transmission gear, and the output component is a transmission rack. The two output components are respectively connected to the radial sides of the transmission component 133 and mesh with the transmission component 133. The output components are movably disposed on the support base 111 along the line connecting the second blocking component 122 and the fourth blocking component 124. When the transmission component 133 rotates, the meshing relationship drives the two output components to move in opposite directions, thereby causing the second blocking component 122 and the fourth blocking component 124 to move closer to or further away from each other.

[0086] Of course, in other embodiments of this application, the transmission component 133 and the output component are belt drive components or chain drive components, and their arrangement is substantially the same as the arrangement of the moving components as belt drive components or chain drive components mentioned above, which will not be repeated here.

[0087] See Figures 2 to 6In one embodiment of this application, in the first transmission structure 103, the two sets of moving components are ball screw components, and the two ball screw components are connected by a bevel gear transmission adapter 132, so that the two sets of moving components can move synchronously, thereby causing the first blocking component 121 and the third blocking component 123 to move closer to or further away from each other. In the second transmission structure 104, the transmission component 133, which is a screw shaft, is connected to an output component, a screw nut, by two opposite helical portions. When the transmission component 133 moves, it can drive the second blocking component 122 and the third blocking component 123 to move closer to or further away from each other through the two output components.

[0088] For example, the first transmission structure 103 drives the first blocking component 121 and the third blocking component 123 to move closer together, and the second transmission structure 104 drives the second blocking component 122 and the fourth blocking component 124 to move closer together, thereby reducing the size of the accommodating space 101 so that the loading box 100 can hold smaller-sized battery cells. The first transmission structure 103 drives the first blocking component 121 and the third blocking component 123 to move further apart, and the second transmission structure 104 drives the second blocking component 122 and the fourth blocking component 124 to move further apart, thereby increasing the size of the accommodating space 101 so that the loading box 100 can hold larger-sized battery cells.

[0089] Of course, the first transmission structure 103 drives the first blocking component 121 and the third blocking component 123 to move, and the second transmission structure 104 drives the second blocking component 122 and the fourth blocking component 124 to move by the same or different distances, so that the feeding box 100 can carry battery cells of different sizes. Alternatively, the first transmission structure 103 drives the first blocking component 121 and the third blocking component 123 to move closer to each other, and the second transmission structure 104 drives the second blocking component 122 and the fourth blocking component 124 to move further apart, etc.

[0090] Of course, the first transmission structure 103 and the second transmission structure 104 can also be interchanged. In other possible implementations of this application, the first transmission structure 103 and the second transmission structure 104 are not limited to the lead screw drive component 133, but can also be chain drive components or belt drive components, as long as there is no interference between the first transmission structure 103 and the second transmission structure 104.

[0091] See Figures 2 to 5 , Figure 7 In one embodiment, both the first transmission structure 103 and the second transmission structure 104 further include an adjustment knob 134. The adjustment knob 134 is disposed at the end of the moving component and the transmission component 133, and the adjustment knob 134 can drive the moving component and the transmission component 133 to rotate. Figure 7 for Figure 3The diagram shows a partial enlarged view at point B of the support base 111 supporting the transmission structure 130 and the blocking component 120.

[0092] The adjusting knob 134 serves as the power input for both the first transmission structure 103 and the second transmission structure 104. The adjusting knob 134 is located at at least one end of the lead screw shaft 131 in the moving assembly, and also at at least one end of the transmission component 133, which is also the lead screw shaft. When the adjusting knob 134 rotates, it drives the lead screw shaft 131 and the transmission component 133 to rotate. Consequently, when the lead screw shaft 131 rotates, it drives the first blocking component 121 and the third blocking component 123 to move closer or further apart. Similarly, when the transmission component 133 rotates, it drives the second blocking component 122 and the fourth blocking component 124 to move closer or further apart.

[0093] It is worth noting that the connection method between the adjusting knob 134, the lead screw shaft 131, and the transmission component 133 is essentially the same. This application only uses the connection between the adjusting knob 134 and the lead screw shaft 131 as an example for explanation. One end of the lead screw shaft 131 has a first mating part 1311, and the end of the adjusting knob 134 facing the lead screw shaft 131 has a second mating part 1341. When the adjusting knob 134 is connected to the lead screw shaft 131, the first mating part 1311 and the second mating part 1341 are engaged and connected. When the adjusting knob 134 rotates, the engagement of the second mating part 1341 and the first mating part 1311 can drive the lead screw shaft 131 to rotate synchronously.

[0094] Optionally, the first mating part 1311 and the second mating part 1341 are a protrusion and groove mating structure. Further, the first mating part 1311 is a groove and the second mating part 1341 is a protrusion. Of course, in other embodiments of this application, the first mating part 1311 may be a protrusion and the second mating part 1341 may be a groove, or the first mating part 1311 and the second mating part 1341 may be a shaft-hole interference fit, a snap-fit ​​fit, etc.

[0095] See Figures 2 to 7 In one embodiment, the support base 111 has multiple fixing portions 1111, with at least one fixing portion 1111 corresponding to each end of the moving component and the transmission component 133. The fixing portions 1111 are rotatably supporting the moving component and the transmission component 133. The fixing portions 1111 are disposed on the upper surface of the support base 111 and protrude toward the support cover 112. The two ends of the lead screw shaft 131 and the transmission component 133 are rotatably disposed on the fixing portions 1111. In this way, the fixing portions 1111 can provide rotatable support for the lead screw shaft 131 and the transmission component 133, ensuring that the lead screw shaft 131 and the transmission component 133 can rotate normally and avoiding interference with the support base 111. In this embodiment, the fixing portion 1111 is a fixing protrusion or the like.

[0096] See Figures 2 to 5 In one embodiment, the first transmission structure 103 further includes a first guide rail 135 disposed on the support base 111, and a first blocking member 121 and / or a third blocking member 123 slidably disposed on the first guide rail 135. The first guide rail 135 extends along the line connecting the first blocking member 121 and the third blocking member 123. The first blocking member 121 and the third blocking member 123 share the same first guide rail 135, or each corresponds to a first guide rail 135. When the lead screw 131 drives the first blocking member 121 and the third blocking member 123 to move closer to or further away from each other, the first blocking member 121 and the third blocking member 123 can slide along the first guide rail 135 to ensure the accuracy of the movement trajectory of the first blocking member 121 and the third blocking member 123.

[0097] Optionally, the bottom of the first blocking member 121 and the third blocking member 123 has a first guide groove (not shown), and the first blocking member 121 and the third blocking member 123 are slidably disposed on the first guide rail 135 through the first guide groove. Of course, in other embodiments of this application, the bottom of the first blocking member 121 and the third blocking member 123 may also be provided with a first guide slider, and the first blocking member 121 and the third blocking member 123 are slidably disposed on the first guide rail 135 through the first guide slider.

[0098] See Figures 2 to 5 In one embodiment, the second transmission structure 104 further includes a second guide rail 136 disposed on the support base 111, and a second blocking member 122 and / or a fourth blocking member 124 slidably disposed on the second guide rail 136. The second guide rail 136 extends along the line connecting the second blocking member 122 and the fourth blocking member 124. The second blocking member 122 and the fourth blocking member 124 share the same second guide rail 136, or each corresponds to a separate second guide rail 136. When the transmission member 133 drives the second blocking member 122 and the fourth blocking member 124 to move closer to or further away from each other, the second blocking member 122 and the fourth blocking member 124 can slide along the second guide rail 136 to ensure the accuracy of the movement trajectory of the second blocking member 122 and the fourth blocking member 124.

[0099] Optionally, the bottom of the second blocking member 122 and the fourth blocking member 124 has a second guide groove (not shown), and the second blocking member 122 and the fourth blocking member 124 are slidably disposed on the second guide rail 136 through the second guide groove. Of course, in other embodiments of this application, the bottom of the second blocking member 122 and the fourth blocking member 124 may also be provided with a second guide slider, and the second blocking member 122 and the fourth blocking member 124 are slidably disposed on the second guide rail 136 through the second guide slider.

[0100] See Figures 2 to 5 In one embodiment, the blocking component 120 includes opposing stop bars 125 and a connecting portion 126 connecting the two stop bars 125. The connecting portion 126 is drive-connected to the transmission structure 130, and the stop bars 125 extend through the adjustment hole 1121. That is, the blocking component 120 is a rod, the stop bars 125 extend along the height direction, the connecting portion 126 connects the bottoms of the two stop bars 125, and the transmission structure 130 is drive-connected to the connecting portion 126. When the transmission structure 130 moves, it can drive the connecting portion 126 to move, and then drive the stop bars 125 to move through the connecting portion 126, so as to adjust the distance between each set of stop bars 125, thereby adjusting the size of the feeding box 100.

[0101] The support cover 112 is provided with rectangular adjustment holes 1121. When the transmission structure 130 drives the stop lever 125 to move, the stop lever 125 can move in the adjustment holes 1121. The number of adjustment holes 1121 on the support cover 112 is the same as the number of stop levers 125. Of course, the number of stop levers 125 can also be one, three, or even more.

[0102] In another embodiment of this application, the blocking member 120 includes a baffle and a support portion disposed at one end of the baffle. The support portion is drively connected to the transmission structure 130, and the baffle extends through the adjustment hole 1121. That is, in this embodiment, the blocking member 120 is plate-shaped, the baffle extends along the height and width directions, the bottom of the baffle is provided with a support portion, the transmission structure 130 drives the support portion to move, and then drives the baffle to move through the support portion.

[0103] See Figure 1 , Figure 2 , Figures 8 to 11 In one embodiment, the loading box 100 further includes an RFID tag 140 and a locking structure 150. The support base 111 includes a mounting base 1112 and a mounting plate 1113. The RFID tag 140 is disposed on the mounting base 1112, and the mounting plate 1113 covers the mounting base 1112. The locking structure 150 is disposed on the mounting base 1112 and can engage the mounting plate 1113 to lock the mounting plate 1113 to the mounting base 1112. Figure 8 for Figure 1 An exploded view of the support structure 110 in the feeding box 100 shown. Figure 9 for Figure 2 A schematic diagram of the locking structure 150 in the feed box 100 from one perspective. Figure 10 for Figure 9 An exploded view of the locking structure 150 shown. Figure 11 for Figure 9 A schematic diagram of the locking structure 150 shown from another perspective.

[0104] The solar cells are transported to the unpacking room, where they are unpacked manually. The box number and individual package number of each cell are scanned and linked to the RFID chip 140 for onboarding. This allows for marking of the solar cells at each stage of the photovoltaic module's production process, facilitating later traceability of the cell information. In this application, the RFID chip 140 is an RFID (Radio Frequency Identification) chip.

[0105] In the past, RFID tags were located between the base and the top cover of the cassette, making them prone to falling off during replacement. To address this, this application splits the support base 111 into a mounting base 1112 and a mounting plate 1113. The RFID tag 140 is mounted on the mounting base 1112, the mounting plate 1113 covers the mounting base 1112, and the top cover 112 covers the support base 111. This secures the RFID tag 140 between the mounting plate 1113 and the mounting base 1112, preventing it from falling off.

[0106] Meanwhile, this application provides a locking structure 150 in the support base 111, which is disposed on the mounting base 1112. The locking structure 150 can engage or disengage from the mounting plate 1113. When the locking structure 150 engages with the mounting plate 1113, it secures the mounting plate 1113 to the mounting base 1112, at which point the mounting plate 1113 secures the RFID device 140 to the mounting base 1112. When the locking structure 150 disengages from the mounting plate 1113, it unlocks the mounting plate 1113 from the mounting base 1112, allowing the mounting plate 1113 to detach from the mounting base 1112 for easy replacement of the RFID device 140.

[0107] The loading box 100 of this application uses a locking structure 150 to lock the mounting plate 1113, which can prevent the mounting plate 1113 from shifting relative to the mounting base 1112, and thus prevent the RFID component 140 from shifting, ensuring that the RFID component 140 is reliably fixed. In this embodiment, the loading box 100 includes two locking structures 150, which are symmetrically arranged. Of course, in other embodiments of this application, the loading box 100 may also include one locking structure 150.

[0108] See Figure 1 and Figure 2 In one embodiment, the support cover 112 has a through-hole 1122 through which the locking structure 150 can extend. When the RFID component 140 needs to be replaced, the operator operates the locking structure 150 that exposes the unlocking hole 1122 to unlock the mounting plate 1113.

[0109] The specific structure of the locking structure 150 is not limited in principle, as long as the locking structure 150 can lock and unlock the mounting plate 1113. The following describes one possible way to implement the locking structure 150.

[0110] See Figure 1 , Figure 2 , Figures 6 to 9 In one embodiment, the locking structure 150 includes a pusher 151, a pull rod 152, an elastic member 154, a linkage group 153, and a locking member 155. The pusher 151 is movably mounted on the linkage group 153 along the height direction. The linkage group 153 is connected to the locking member 155 and is mounted on the pull rod 152. The pull rod 152 is mounted on the mounting base 1112. The locking member 155 is slidably mounted on the mounting base 1112. The elastic member 154 is sleeved on the pull rod 152, with its two ends abutting against the pull rod 152 and the locking member 155. The elastic force of the elastic member 154 can push the locking member 155 to engage with the mounting plate 1113. The pressing force of the pusher 151 can drive the locking member 155 to compress the elastic member 154 through the linkage group 153, causing the locking member 155 to disengage from the mounting plate 1113.

[0111] The push button 151 is rotatably connected to one end of the linkage assembly 153, which is rotatably mounted on the pull rod 152. The other end of the linkage assembly 153 is rotatably connected to the locking member 155. Optionally, the elastic member 154 is a spring. When the user operates the push button 151 downwards, the push button 151 drives the linkage assembly 153 to move towards the inside of the receiving space 101. This causes the linkage assembly 153 to pull the locking member 155 against the elastic force of the elastic member 154, allowing the locking member 155 to move along the pull rod 152 and disengage from the mounting plate 1113, thus unlocking the mounting plate 1113. After releasing the push button 151, the elastic force of the elastic member 154 pushes the locking member 155 towards the outside of the receiving space 101, causing the locking member 155 to engage with the mounting plate 1113.

[0112] In one embodiment, the pull rod 152 has an inclined guide surface 1521. When the pusher 151 is operated downward, the pusher 151 can move downward along the guide surface 1521, ensuring that the guide can accurately drive the linkage 153 to drive the locking member 155 to compress the elastic member 154. Optionally, one end of the locking member 155 has an inclined surface, so that the locking member 155 forms a tip, and the locking member 155 is engaged with the mounting plate 1113 through the tip. In one embodiment, the mounting base 1112 and / or the mounting plate 1113 have a mounting groove 11121 for accommodating the radio frequency identification member 140.

[0113] In one embodiment, the locking structure 150 further includes a mounting housing 156, a pull rod 152 fixedly disposed in the mounting housing 156, a guide rail 1561 on the side wall of the pull rod 152, and a guide groove 1551 on the side wall of the locking member 155. The locking member 155 is slidably disposed on the guide rail 1561 through the guide groove 1551. When the locking member 155 compresses the elastic member 154 or the elastic member 154 pushes the locking member 155 to move, the locking member 155 can move along the guide rail 1561 through the guide groove 1551, ensuring the accurate movement trajectory of the locking member 155.

[0114] In one embodiment of this application, the support cover 112 is made of stainless steel, hollow or solid aluminum alloy, or a composite material. The support cover 112 has multiple rectangular adjustment holes 1121, multiple unlocking holes 1122, and a circular hole for mounting the adjustment knob 134. Exemplarily, the support cover 112 has a length of 230mm to 270mm, a width equal to its length, a height of 30mm, and a thickness of 5mm. This support cover 112 provides space for the installation of the transmission structure 130, the locking structure 150, and the adjustment knob 134, and also supports the battery cells.

[0115] The blocking component 120 is made of the same material as the supporting cover 112. The blocking component 120 has a first guide groove and a second guide groove at its lower part. The supporting base 111 has a first guide rail 135 and a second guide rail 136. The movement of the blocking component 120 is guided by the cooperation of the guide grooves and guide rails. The blocking component 120 has a height of 105mm~150mm and a thickness of 10mm~15mm. The height and width of the first and second guide grooves are 8mm~12mm. This blocking component 120 can limit the movement of the battery cells.

[0116] In the first transmission structure 103, the lead screw shaft 131 is made of stainless steel, aluminum alloy, or a composite material, and the helical direction of the lead screw shaft 131 in both sets of moving components is the same. The first bevel gear 1321, second bevel gear 1322, and third bevel gear 1323 of the adapter component 132 are made of stainless steel or aluminum alloy. The first bevel gear 1321 and second bevel gear 1322 mesh with the third bevel gear 1323 respectively. The second bevel gear 1322 rotates counterclockwise, and conversely, when the first bevel gear 1321 rotates counterclockwise, the second bevel gear 1322 rotates clockwise, so that the first transmission structure 103 drives the first blocking component 121 and the third blocking component 123 to move closer or further apart. The width and height of the first bevel gear 1321, second bevel gear 1322, and third bevel gear 1323 are 20mm~25mm.

[0117] In the second transmission structure 104, the transmission component 133 of the lead screw shaft is made of stainless steel, aluminum alloy, or composite material. The transmission component 133 has two threaded parts with opposite helical directions. When the second transmission structure 104 rotates, it can drive the two output components to output opposite movements through the two threaded parts with opposite helical directions, thereby driving the second blocking component 122 and the fourth blocking component 124 to move closer to or further away from each other.

[0118] Furthermore, the lead screw shaft 131 and the adjusting knob 134 are connected by a first mating part 1311 and a second mating part 1341. The lead screw shaft 131 has a length of 73mm to 85mm and a diameter of 10mm to 20mm, and the length of the transmission component 133 is at least twice the length of the lead screw shaft 131. The adjusting knob 134 has a length of 15mm to 20mm and a diameter of 8mm to 12mm. Thus, when the adjusting knob 134 is rotated, the ball screw component allows the various sets of blocking components 120 to move closer to or further away from each other.

[0119] Mounting plate 1113 covers mounting base 1112 to form support base 111. Mounting plate 1113 is made of stainless steel, hollow or solid aluminum alloy, or composite material. Mounting plate 1113 has a first guide rail 135 and a second guide rail 136 to mate with the first and second guide grooves of blocking component 120. The dimensions of mounting plate 1113 are the same as those of support cover 112. The surface of mounting plate 1113 facing mounting base 1112 has mounting groove 11121 for mounting RFID component 140. The depth of mounting groove 11121 is 3mm~7mm, and the diameter of mounting groove 11121 is the same as the diameter of RFID component 140. The height and width of the first guide rail 135 and the second guide rail 136 are 8mm~12mm. Mounting plate 1113 provides support for transmission structure 130.

[0120] The mounting base 1112 is made of stainless steel, hollow or solid aluminum alloy, or composite materials. The mounting plate 1113 and locking structure 150 are disposed within the mounting base 1112. The mounting base 1112 also has a mounting groove 11121 for accommodating the RFID component 140. The RFID component 140 is fixed by the cooperation between the mounting base 1112 and the mounting plate 1113. The mounting base 1112 has a length of 230mm to 270mm, a width equal to its length, a height of 13mm to 17mm, and a thickness of 5mm. The mounting groove 11121 has a depth of 3mm to 7mm.

[0121] In the locking structure 150, the elastic element 154 is a spring, and the materials of the remaining components are the same as those of the mounting plate 1113. The locking structure 150 is installed into the rectangular groove of the mounting base 1112. The locking structure 150 can lock the mounting plate 1113 and the mounting base 1112 together to fix the RFID tag. When the push button 151 is pressed, the push button 151 drives the locking element 155 through the linkage assembly 153 to overcome the elastic force of the elastic element 154, causing the locking element 155 to disengage from the mounting plate 1113. At this time, the mounting plate 1113 and the RFID tag 140 can be removed for easy replacement of the RFID tag 140.

[0122] It is worth noting that the above only illustrates one possible form of material and size for the feeding box 100. However, the materials and sizes of the feeding box 100 are not limited to those mentioned above and can also be other.

[0123] When replacing the RFID component 140 in the loading box 100 of this application, the user presses down on the actuating member 151 with their thumb while holding the mounting plate 1113 with their other fingers. At this time, the actuating member 151 moves downward and pulls the locking member 155 to overcome the elastic force of the elastic member 154, causing the locking member 155 to disengage from the mounting plate 1113. After lifting the mounting plate 1113, the RFID component 140 can be replaced. After replacement, the mounting plate 1113 is installed onto the mounting base 1112. The locking member 155 is pushed by the elastic member 154 to lock the mounting plate 1113 onto the mounting base 1112.

[0124] When the size of the loading box 100 needs to be adjusted, the adjustment knob 134 corresponding to the first transmission structure 103 is adjusted. The first transmission structure 103 drives the first blocking component 121 and the third blocking component 123 to move closer or further apart along the first guide slide rail 135 through the moving component and the adapter component 132. The adjustment knob 134 corresponding to the second transmission structure 104 is adjusted. The transmission component 133 in the second transmission structure 104 drives the second blocking component 122 and the fourth blocking component 124 to move closer or further apart along the second guide slide rail 136 through the two output components, so as to adjust the size of the accommodating space 101, thereby realizing the adjustment of the size of the loading box 100 so that the loading box 100 can carry the battery cells of the corresponding size.

[0125] The feeding box 100 of this application drives the blocking components 120 to move via the transmission structure 130, so that at least two sets of blocking components 120 can move to the inside or outside of the receiving space 101, thereby reducing or increasing the size of the receiving space 101 and adjusting the size of the feeding box 100. In this way, the feeding box 100 can accommodate battery cells of different sizes, eliminating the need for multiple sizes of feeding boxes 100, reducing production costs and complexity.

[0126] Meanwhile, the transmission structure 130 can simultaneously drive at least two sets of blocking components 120 to move synchronously, simplifying the adjustment process of the blocking components 120, shortening the time consumed in the adjustment process, improving the adjustment efficiency of the loading box 100 size, and thus improving the production efficiency of photovoltaic modules. Furthermore, all components in the loading box 100 are detachably connected, so when a part is damaged, the corresponding part can be replaced, reducing maintenance costs.

[0127] This application also provides a photovoltaic module production equipment, including a conveyor line, a welding device, and a loading box 100 as described in any of the above embodiments. The loading box 100 carries solar cells of corresponding sizes. The welding device is disposed on the side of the conveyor line for welding the solar cells into battery strings. The conveyor line transports the loading box 100 carrying the solar cells to the welding device and then transports the battery strings to the next process. By using the loading box 100 of the above embodiments, the photovoltaic module production equipment of this application can realize the transport of solar cells of different sizes, thereby producing photovoltaic modules of different specifications, reducing production costs and complexity, improving the adjustment efficiency of the loading box 100 size, and thus improving the production efficiency of photovoltaic modules.

[0128] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0129] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
