Description

Technical Field

[0001] This utility model relates to the field of battery cell transmission technology, and in particular to a battery cell transmission device and a battery cell transmission system. Background Technology

[0002] In the solar cell manufacturing process, high-speed tracks are typically used to transport solar cells. After the cells are placed on the track, their relatively long length results in a concave shape in the middle. To prevent this concave portion from rubbing against the track and causing damage, existing high-speed tracks are equipped with support points to hold the concave portion of the cells. However, when these support points become dirty or worn, the contact and friction between the dirty and worn support points and the cells during transport on the track can lead to a risk of batches of defective support point markings. Utility Model Content

[0003] Therefore, it is necessary to provide a cell transfer device and cell transfer system to address the problem that dirt and wear on the fulcrum during the use of high-speed tracks in the prior art can lead to a risk of batch fulcrum defects in the cells.

[0004] The technical solution is as follows:

[0005] On one hand, a cell transport device is provided, comprising:

[0006] The transmission mechanism includes a first transmission member and a second transmission member, the first transmission member and the second transmission member being spaced apart to form an air blowing space between them;

[0007] An air blowing mechanism is provided with an air blowing port, which is located within the air blowing space and faces upward.

[0008] When the first and second transmission components cooperate to carry the battery cell and transport the battery cell to a position above the air inlet, the air inlet blows air toward the battery cell to lift the portion of the battery cell located between the first and second transmission components.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, the number of air inlets is at least one, and each air inlet is spaced apart along the conveying direction of the battery cell.

[0011] In one embodiment, the air blowing mechanism further includes at least one control valve, each of the control valves being installed correspondingly at each of the air blowing ports. The battery cell conveying device further includes a controller and at least one detection element. The controller is communicatively connected to each of the detection elements and each of the control valves. Each of the detection elements is correspondingly set to each of the air blowing ports. The detection element is used to detect whether there is a battery cell above the corresponding air blowing port.

[0012] In one embodiment, both the first and second transmission components are configured as transmission belts. The battery cell transmission device further includes a mounting body. The transmission mechanism further includes two pulleys, which are rotatably mounted on opposite ends of the mounting body. The two transmission belts are sleeved on the outer walls of the two pulleys. The mounting body is provided with at least one air-blowing hole group. Each air-blowing hole group is correspondingly connected to each air-blowing port. Each air-blowing hole group is located within the air-blowing space and blows air upwards.

[0013] In one embodiment, each of the detection elements is installed at intervals on the mounting body along the conveying direction of the battery cell. The number of air inlets, the number of detection elements, and the number of air hole groups are all the same. Each air hole group has at least two air holes. All the air holes in each air hole group are connected to the corresponding air inlet and are respectively arranged on opposite sides of the corresponding detection element along the conveying direction of the battery cell.

[0014] In one embodiment, the transmission mechanism further includes a limiting member, which is installed on both the first and second transmission members. The limiting member is configured to limit the movement of the battery cell along the transmission direction of the battery cell when the first and second transmission members cooperate to carry the battery cell.

[0015] In one embodiment, both the first and second transmission components are configured as transmission belts, and at least two limiting members are installed on the outer side walls of the two transmission belts at circumferential intervals along the transmission belts. The spacing between two adjacent limiting members on each transmission belt is adapted to the length of the battery cell.

[0016] On the other hand, a battery cell transfer system is provided, including a lifting platform and the battery cell transfer device, wherein the lifting platform is used to place the battery cell on the battery cell transfer device.

[0017] In one embodiment, the number of the cell transport devices is at least one, and each of the cell transport devices is located on the same horizontal plane and is spaced apart along a direction perpendicular to the transport direction of the cells.

[0018] In one embodiment, the top of the lifting platform is provided with a lifting part, and each of the battery cell conveying devices has at least one lifting part on both sides along the conveying direction perpendicular to the battery cell, and each of the lifting parts is controlled to lift and lower so as to place the battery cell on the respective battery cell conveying device.

[0019] In the above embodiments, when the first and second transport members cooperate to carry the battery cells and transport them above the air blowing port, the air blowing port blows air towards the battery cells to lift the portion of the battery cells located between the first and second transport members. This ensures that the portion of the battery cells between the first and second transport members does not rub against the battery cell transport device as it passes above the air blowing port, reducing the number of contact points between the battery cells and the battery cell transport device during transport and improving the yield of battery cell processing. Furthermore, this application replaces the existing fulcrum-lifting method with an air blowing port, avoiding the situation where the fulcrum is dirty or worn, leading to poor fulcrum markings in batches of battery cells. It also saves time on replacing dirty or worn fulcrums, effectively improving the production efficiency of the battery cell transport system. Attached Figure Description

[0027] 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.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, a battery cell transfer system is provided, including a lifting platform 30 and a battery cell transfer device 10. The lifting platform 30 is used to place the battery cell 20 on the battery cell transfer device 10.

[0029] When the cell transfer system needs to transfer cell 20, firstly, the lifting platform 30 is raised to the loading position under control. Secondly, after the robotic arm picks up the cell, it places the cell 20 on the lifting platform 30. At this time, the cell 20 is positioned above and spaced apart from the cell transfer device 10. Then, the lifting platform 30 is lowered under control to place the cell 20 onto the cell transfer device 10. Finally, the cell transfer device 10 moves the cell 20 for transfer.

[0030] like Figure 1 As shown, the number of cell transport devices 10 is at least one. Each cell transport device 10 is located on the same horizontal plane and is spaced apart along a direction perpendicular to the transport direction of the cell 20. In this way, multiple cell transport devices 10 can simultaneously transport the cell 20, improving the transport efficiency of the cell transport system.

[0031] It should be noted that the fact that each cell transport device 10 is located on the same horizontal plane means that the surfaces of each cell transport device 10 used to carry the cell 20 are located on the same horizontal plane.

[0032] It should be noted that the lifting platform 30 can be configured as any of the existing structures for lifting and feeding the battery cells 20.

[0033] like Figure 2As shown, optionally, the top of the lifting platform 30 is provided with a lifting section 31. Each cell conveying device 10 has at least one lifting section 31 on both sides along the conveying direction perpendicular to the cell 20, and each lifting section 31 is controlled to lift and lower to place the cell 20 onto the respective cell conveying device 10. In this way, each cell conveying device 10 can share the lifting platform 30 to load cells simultaneously, reducing the production cost of the cell conveying system.

[0034] like Figure 1 As shown, in one embodiment, a battery cell transfer device 10 is provided, including a transfer mechanism 100 and an air blowing mechanism. The transfer mechanism 100 includes a first transfer member 110 and a second transfer member 120, which are spaced apart to form an air blowing space 130 between them. The air blowing mechanism has an air blowing port located within the air blowing space 130 and facing upwards.

[0035] In the above embodiment, when the first transport member 110 and the second transport member 120 cooperate to carry the battery cell 20 and transport the battery cell 20 above the air blowing port, the air blowing port blows air towards the battery cell 20 to lift the portion of the battery cell 20 located between the first transport member 110 and the second transport member 120. This ensures that the portion of the battery cell 20 between the first transport member 110 and the second transport member 120 does not rub against the battery cell transport device 10 during the process of passing above the air blowing port, reducing the number of contact points between the battery cell 20 and the battery cell transport device 10 during transport and improving the yield of the battery cell 20 processing. In addition, this application replaces the fulcrum lifting method in the prior art with the air blowing lifting method of the air blowing port, avoiding the situation where the fulcrum of the battery cell 20 is poorly printed due to dirt or wear, and also saving the time of replacing dirty or worn fulcrums, effectively improving the production efficiency of the battery cell transport system.

[0036] It should be noted that the transmission mechanism 100 can be configured as any existing transmission structure for transmitting the battery cells 20. Specifically, in this embodiment, the transmission mechanism 100 is configured as a dual-belt transmission structure.

[0037] It should be noted that the air blowing mechanism can be configured using any existing air blowing structure. The number and shape of the air blowing ports can be flexibly adjusted according to the actual needs of use.

[0038] like Figure 1 and Figure 3 As shown, optionally, the number of air inlets is at least one, and each air inlet is along the conveying direction of the battery cell 20 (e.g., Figure 1(As shown in direction B) The air inlets are spaced apart. In this way, by setting air inlets at multiple points along the path of the solar cell 20, it is ensured that the solar cell 20 will not rub against the solar cell transport device 10 during the transport process, thereby improving the reliability of the solar cell transport device 10.

[0039] In other embodiments, the air inlet may also be flat and arranged along the conveying direction of the battery cell 20 to ensure that the battery cell 20 does not rub against the battery cell conveying device 10 during the transmission process.

[0040] like Figure 2 and Figure 3 As shown, in one embodiment, the air blowing mechanism further includes at least one control valve, with each control valve correspondingly installed at each air blowing port. The battery cell transfer device 10 also includes a controller and at least one detection element 210, with the controller communicatively connected to each detection element 210 and each control valve. Each detection element 210 is correspondingly configured to each air blowing port, and the detection element 210 is used to detect whether there is a battery cell 20 above the corresponding air blowing port. Thus, when the battery cell 20 is transferred to the air blowing port, the detection element 210 corresponding to that air blowing port detects the battery cell 20 and feeds back the detection result to the controller. The controller sends an opening signal to the control valve according to the feedback result, and the control valve opens according to the opening signal, so that the air blowing port blows air towards the battery cell 20 portion located between the first transfer element 110 and the second transfer element 120, thereby lifting the concave portion of the battery cell 20 and ensuring that the battery cell 20 does not rub against the battery cell transfer device 10 during the transfer process, thus improving the processing yield of the battery cell 20. Similarly, when the battery cell 20 passes above the air outlet, the detection element 210 corresponding to the air outlet cannot detect the battery cell 20 and feeds the detection result back to the controller. The controller sends a shut-off signal to the control valve according to the feedback result, and the control valve closes according to the shut-off signal, thereby improving the practicality of the battery cell transmission device 10.

[0041] The detection element 210 can be configured as an infrared sensor, a camera, or other detection structure capable of detecting whether there is a battery cell 20 above the air blowing port. The controller can be configured as a microcontroller, a programmable logic controller, or other control structure. The controller can communicate with the detection element 210 and the control valve via wires, data cables, Bluetooth, wireless network communication technology, or other communication methods. Specifically, in this embodiment, the control valve can be configured as a solenoid valve. The air blowing mechanism also includes a pressure regulating valve that is communicatively connected to the controller and is installed at the air blowing port. In this way, the controller can send a pressure regulating signal to the pressure regulating valve, so that the pressure regulating valve can adjust the amount of gas at the air blowing port according to the pressure regulating signal.

[0042] In other embodiments, the cell transfer device 10 may also not include the detection element 210, for example, the air outlet remains open during the transfer of the cell 20 by the transfer mechanism 100 to continuously blow air.

[0043] like Figure 2 and Figure 3 As shown, both the first transmission member 110 and the second transmission member 120 are configured as transmission belts. The cell transmission device 10 also includes a mounting body 300. The transmission mechanism 100 also includes two pulleys 140, which are rotatably mounted on opposite ends of the mounting body 300. Both transmission belts are sleeved on the outer walls of the two pulleys 140. The mounting body 300 is provided with at least one air-blowing hole group 310, each air-blowing hole group 310 correspondingly communicating with each air-blowing port, and each air-blowing hole group 310 is located within the air-blowing space 130 and blows air upwards. In this way, the air-blowing hole group 310 can divert the gas blown out of the air-blowing port, thereby increasing the range of gas blowing out, and making the force on the cell 20 more uniform when passing above the air-blowing port, thus improving the reliability of the cell transmission device 10.

[0044] It should be noted that each air-blowing hole group 310 is connected to each air-blowing port. It can be that one air-blowing port is connected to one air-blowing hole group 310, or one air-blowing port is connected to multiple air-blowing hole groups 310.

[0045] like Figure 2 and Figure 3 As shown, optionally, each detection element 210 is installed at intervals on the mounting body 300 along the conveying direction of the battery cell 20. The number of air inlets, the number of detection elements 210, and the number of air inlet groups 310 are all the same. Each air inlet group 310 has at least two air inlets 311, and all air inlets 311 in each air inlet group 310 are connected to the corresponding air inlet and are respectively arranged on opposite sides of the corresponding detection element 210 along the conveying direction of the battery cell 20.

[0046] Specifically, in this embodiment, the mounting body 300 is also provided with a clearance hole 320 for avoiding the lifting part 31. Each air blowing hole 311 penetrates the mounting body 300 in a vertical direction. The air blowing port and each air blowing hole 311 can be connected by a pipe. Each detection element 210 is located within the air blowing space 130.

[0047] like Figure 2 and Figure 3As shown, in one embodiment, the transmission mechanism 100 further includes a limiting member 150. The limiting member 150 is installed on both the first transmission member 110 and the second transmission member 120. The limiting member 150 is configured to limit the movement of the battery cell 20 along its transport direction when the first transmission member 110 and the second transmission member 120 are used to support the battery cell 20. Thus, the limiting member 150 can restrict the movement of the battery cell 20 relative to the first transmission member 110 and the second transmission member 120 during transmission, ensuring the accuracy of the battery cell 20 placed on the transmission mechanism 100 and improving the practicality of the battery cell transmission device 10.

[0048] The limiting component 150 can be configured as a limiting block, limiting seat, limiting pin, or other limiting structure. The number of limiting components 150 can be flexibly adjusted according to actual usage needs. The limiting component 150 can be installed on the first transmission component 110 and the second transmission component 120 by screwing, snapping, plugging, gluing, or other methods.

[0049] like Figure 1 As shown, optionally, both the first transmission member 110 and the second transmission member 120 are configured as transmission belts, and at least two limiting members 150 are installed on the outer side walls of both transmission belts at circumferential intervals. The spacing between two adjacent limiting members 150 on each transmission belt is adapted to the length of the battery cell 20. In this way, one battery cell 20 can be fixed between two adjacent limiting members 150 on the transmission belt, improving the practicality of the battery cell transmission device 10.

[0050] Specifically, in this embodiment, along the transmission direction of the battery cell 20, all the limiting members 150 on the two transmission belts are set one-to-one. In other words, all the limiting members 150 on the two transmission belts are symmetrically arranged on both sides of the air blowing space 130.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0057] 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.

[0058] The above embodiments merely illustrate 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.
