[0039] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0040] See also Figures 1 to 5 The embodiment of the present application provides a battery cell transport device, which includes a box body and a barrier rod 30. The following is a detailed description:

[0041] The box body is a rectangular cube with an open side. It includes a top plate 21 and a bottom plate 22, two side panels 23, and a back panel 25 that spans the two side panels 23. The opening of the box body is opposite the back panel 25. A slot 231 for holding a battery cell is provided on the side of the two side panels 23 that are adjacent to each other.

[0042] When storing multiple battery cells, the multiple battery cells in the box can be stacked in sequence along the arrangement direction of the card slots 231. The multiple battery cells will not contact each other, avoiding contact and friction between the battery cell surfaces and protecting the surface and performance of the battery cells.

[0043] The blocking rod 30 is detachably connected between the bottom plate 22 and the top plate 21 and is disposed corresponding to the opening of the box body. The blocking rod 30 is used to block the battery cell disposed in the card slot 231 .

[0044] When transporting the battery cells, the barrier bars 30 can be left uninstalled. Instead, the battery cells can be pushed into the box along the slots 231 on the two side panels 23. The barrier bars 30 can then be installed between the bottom plate 22 and the top plate 21. The barrier bars 30 can hold the battery cells in place within the box, preventing them from slipping out of the opening due to vibrations or careless manual handling during transportation. When the battery cells need to be removed, the barrier bars 30 can be removed to facilitate operation.

[0045] Specifically, in this embodiment, the bottom plate 22 includes a first end and a second end relative to each other, the second end extends out of the opening, a first positioning groove 221 is provided in the middle area of ​​the second end, and the top plate 21 is provided with a first positioning hole 211 corresponding to the first positioning groove 221.

[0046] Please combine Figures 1 to 3 , see Figure 4 A first limit block 301 is provided at one end of the baffle rod 30, and a second limit block 302 is provided at the other end. When the baffle rod 30 is connected between the bottom plate 22 and the top plate 21, one end of the baffle rod 30 is clamped in the first positioning groove 221 through the first limit block 301, and the other end of the baffle rod 30 is clamped in the first positioning hole 211 through the second limit block 302.

[0047] When installing the baffle rod 30, one end of the baffle rod 30 can be inserted downward along the first positioning hole 211 until one end of the baffle rod 30 is stuck in the first positioning groove 221. At this time, the other end of the baffle rod 30 is located in the first positioning hole 211, and the two ends of the baffle rod 30 are respectively limited by the first positioning groove 221 and the first positioning hole 211, so that the baffle rod 30 is fixedly installed on the box body.

[0048] When removing the blocking rod 30 , the end of the blocking rod 30 located at the first positioning hole 211 can be lifted upwards, so that the blocking rod 30 moves along the first positioning hole 211 until it is completely separated from the box body.

[0049] Preferably, the length of the blocking rod 30 is greater than the sum of the distance between the top plate 21 and the bottom plate 22 and the depth of the first positioning groove 221 .

[0050] In this embodiment, a mounting groove (not shown) can be opened on the bottom plate 22 of the box body and any side baffle 23. The shape of the mounting groove matches the baffle rod 30. When the baffle rod 30 is not installed at the opening of the box body, the baffle rod 30 can be clamped and installed in the mounting groove, which is convenient for storage and can prevent the baffle rod 30 from being lost.

[0051] The box body may further include an end cover (not shown), which may be installed at one end of the first positioning hole 211 away from the first positioning groove 221 to close the first positioning hole 211. When the blocking rod 30 is installed in the box body, the end cover is installed in the first positioning hole 211 to limit the movement of the blocking rod 30 in the vertical direction, thereby preventing the blocking rod 30 from falling out of the first positioning groove 221 or the first positioning hole 211 due to factors such as vibration during transportation.

[0052] The barrier rod 30 may be wrapped with a soft layer to prevent the battery cells from making direct hard contact with the barrier rod 30 , thereby reducing the possibility of fragments being generated due to the hard contact between the battery cells and the barrier rod 30 .

[0053] In other embodiments, there may be two or more blocking rods 30, and the number of the first positioning grooves 221 and the first positioning holes 211 corresponds to the number of blocking rods 30, so that multiple blocking rods 30 can be installed at the opening of the box body. The contact area between the battery cell and the multiple blocking rods 30 is larger, which can disperse the pressure generated when the battery cell contacts the blocking rods 30.

[0054] The baffle 30 can also be plate-shaped so that the baffle 30 can cover most of the opening of the box body or completely cover the opening of the box body, thereby evenly distributing the stress generated when the battery cell contacts the baffle 30, reducing the situation where the battery cell and the baffle 30 are excessively stressed and produce fragments.

[0055] Furthermore, in one embodiment, the inner walls of the first positioning groove 221 and the first positioning hole 211 are both magnetic, and the first limiting block 301 and the second limiting block 302 are both magnetic. When the baffle rod 30 is installed across the top plate 21 and the bottom plate 22, the first limit block 301 is magnetically connected to the inner wall of the first positioning groove 221, and the second limit block 302 is magnetically connected to the inner wall of the first positioning hole 211, so that the first limit block 301 and the second limit block 302 can be firmly fixed on the bottom plate 22 and the top plate 21, alleviating the situation of the baffle rod 30 falling off during transportation, and magnetically connecting the first limit block 301 and the second limit block 302 to the inner walls of the first positioning groove 221 and the first positioning hole 211 can ensure the precise matching of the first limit block 301 and the second limit block 302 with the first positioning groove 221 and the first positioning hole 211, which can reduce the situation of operational and installation errors, make the baffle rod 30 easy to install, and improve the safety and reliability of the box body during transportation.

[0056] In one embodiment, see Figures 1 to 3 The second end of the bottom plate 22 is also provided with a second positioning groove 222, the second positioning groove 222 is close to a side baffle 23, and the top plate 21 is also provided with a second positioning hole 212 corresponding to the second positioning groove 222, the second positioning groove 222 is adapted to the first limit block 301, and the second positioning hole 212 is adapted to the second limit block 302.

[0057] When the two ends of the blocking rod 30 are respectively clamped in the second positioning groove 222 and the second positioning hole 212, the blocking rod 30 no longer blocks the opening, making it easier to load the battery cell into the box. When transporting the box, the blocking rod 30 can be lifted upward along the second positioning hole 212 and then inserted downward along the first positioning hole 211 into the first positioning groove 221. When the blocking rod 30 is not in use, the two ends of the blocking rod 30 can be clamped in the second positioning groove 222 and the second positioning hole 212 to prevent the blocking rod 30 from separating from the box and avoid loss of the blocking rod 30. The inner walls of the second positioning groove 222 and the second positioning hole 212 can also be provided with a magnetic structure to enhance the stability of the blocking rod 30 when installed in the second positioning groove 222 and the second positioning hole 212.

[0058] Furthermore, in this embodiment, to facilitate movement of the blocking rod 30 between the first positioning hole 211 and the second positioning hole 212, the bottom plate 22 is further provided with a guide groove 225. The guide groove 225 extends from one side baffle 23 to the other side baffle 23, and the guide groove 225 connects the first positioning groove 221 and the second positioning groove 222. The top plate 21 is further provided with a guide hole 215 that matches the guide groove 225, and the guide hole 215 connects the first positioning hole 211 and the second positioning hole 212.

[0059] When the blocking rod 30 needs to be moved from the first positioning hole 211 to the second positioning hole 212, the blocking rod 30 can be lifted upward along the first positioning hole 211, causing the first stopper 301 of the blocking rod 30 to disengage from the first positioning slot 221 and the second stopper 302 to disengage from the first positioning hole 211. The blocking rod 30 can then be moved laterally along the guide hole 215. This makes the movement of the blocking rod 30 between the first positioning hole 211 and the second positioning hole 212 smoother and more convenient. Furthermore, this movement method limits the movement path of the blocking rod 30, reducing the possibility of misoperation. The operator does not need to worry about the blocking rod 30 deviating from the predetermined path, reducing the risk of error. Furthermore, the blocking rod 30 does not need to be completely disengaged from the first positioning hole 211 or the second positioning hole 212 throughout the entire process, completely avoiding the risk of losing the blocking rod 30.

[0060] Furthermore, in this embodiment, the first limiting block 301 and the second limiting block 302 are both rectangular parallelepiped structures, and the width of the guide groove 225 is greater than the width of the rectangular parallelepiped structure and less than the length of the rectangular parallelepiped structure.

[0061] This arrangement can prevent the blocking rod 30 from rotating in the guide groove 225. When the first limit block 301 is located in the first positioning hole 211, the inner wall of the first positioning hole 211 limits the blocking rod 30, so that the blocking rod 30 cannot rotate about its own axis, thereby ensuring that the blocking rod 30 always maintains the correct direction and avoiding inaccurate positioning or loosening due to rotation.

[0062] When it is necessary to move the blocking rod 30, the blocking rod 30 can be lifted to separate the second limit block 302 of the blocking rod 30 from the first positioning hole 211, and then the blocking rod 30 can be rotated 90°, and the second limit block 302 of the blocking rod 30 can be put back into the first positioning hole 211. The width of the second limit block 302 is smaller than the width of the guide groove 225, so the first limit block 301 can move along the guide groove 225, and the second limit block 302 can move along the guide hole 215. After moving the first limit block 301 from the first positioning groove 221 to the second positioning groove 222, the blocking rod 30 can be lifted out of the second positioning groove 222 and rotated 90°, and then the first limit block 301 of the blocking rod 30 can be put back into the first positioning groove 221, and the second limit block 302 can be put back into the second positioning hole 212. Preferably, the length of the second limiting block 302 is greater than the width of the guide groove 225 , which can prevent the second limiting block 302 from sliding along the guide groove 225 when the long side faces the guide groove 225 .

[0063] In one embodiment, see Figure 5 To reduce the fragmentation rate of the battery cells in the box during transportation, the back plate 25 is made of rubber. The rubber back plate 25 can cushion the contact between the battery cells and the back plate 25, thereby alleviating the problem of battery cells and back plate 25 being broken into pieces due to hard contact.

[0064] In other embodiments, the material of the back plate 25 may also be other soft materials, such as foam plastic, silicone, etc., as long as the buffer battery cell can be in contact with the back plate 25 .

[0065] Specifically, since the back panel 25 is relatively soft and difficult to fix to the base plate 22, in this embodiment, two or more fixing rods 253 can be installed on the base plate 22, and the multiple fixing rods 253 are vertically fixed to the base plate 22, and the back panel 25 is fixed to the multiple fixing rods 253 to provide support for the back panel 25 through the multiple fixing rods 253.

[0066] In order to facilitate loading the battery cells into the box body, in one embodiment, the two side baffles 23 are provided with a plurality of scale marks (not shown) at one end close to the opening of the box body. The plurality of scale marks are arranged in sequence along the height direction of the side baffles 23, and the scale marks on the two side baffles 23 are the same.

[0067] The scale markings can be numbers or letters arranged in a reasonable order along the height direction of the side panels 23, such as 1, 2, 3, 4, ... 100; or A, B, C, ... Z. When loading the battery cells, the ends of the battery cells can be installed into the slots 231 at the positions corresponding to the same scale markings on the two side panels 23. The scale markings can help the operator load the battery cells correctly into the box body, avoiding scratches and fragments caused by tilted loading of the battery cells.

[0068] In one embodiment, the top plate 21 has a hollow structure (not shown). This structure significantly reduces the weight of the top plate 21, thereby reducing the overall weight of the box and alleviating the burden of transportation. The hollow structure allows operators to more easily observe the interior of the box, checking the status of the battery cells without having to open the top plate 21. Furthermore, the hollow structure can be designed to be easily gripped, making it easier for operators to grasp the top plate 21 when transporting and securing the box, improving safety and convenience.

[0069] In other embodiments, the two side baffles 23 and the bottom plate 22 may also be provided with corresponding hollow structures, or a weight-increasing plate may be provided on the bottom plate 22 to lower the overall center of gravity of the box body and reduce the risk of tipping.

[0070] An embodiment of the present application further provides a solar cell preparation system, comprising any of the above-mentioned cell transport devices.

[0071] The solar cell preparation system may further include multiple process components, each of which is used to perform different process operations on the cell. The cell transport device may be used to transport the cell between the multiple process components or to transport the prepared cell out.

[0072] The prepared cells can be assembled into photovoltaic modules and used in photovoltaic systems. Photovoltaic systems have a wide range of applications, not limited to photovoltaic power stations, such as ground-based, rooftop, and water-based power stations. They also include various devices and equipment that utilize solar energy for power generation, such as consumer solar power supplies, solar streetlights, solar cars, and solar buildings. Of course, it is understood that the application scenarios of photovoltaic systems are not limited to these. In other words, photovoltaic systems can be used in all areas where solar energy is required for power generation. Taking a photovoltaic power generation system as an example, a photovoltaic system can include a photovoltaic array, a combiner box, and an inverter. A photovoltaic array can be an array combination of multiple photovoltaic modules. For example, multiple photovoltaic modules can form multiple photovoltaic arrays. The photovoltaic arrays are connected to a combiner box, which can combine the current generated by the photovoltaic arrays. The combined current flows through the inverter and is converted into the AC power required by the mains power grid before being connected to the mains power grid to achieve solar power supply.
