Abstract
Description
Technical Field
[0001] This application relates to the field of battery technology, and in particular to conveying devices and battery production lines. Background Technology
[0002] In the battery manufacturing process, conveying devices are typically used to efficiently transfer electrode components between different workstations. However, improving the quality of the electrode components by enhancing the quality of the conveying process is a problem that urgently needs to be solved. Utility Model Content
[0003] Based on this, this application provides a conveying device and a battery production line to improve the quality of electrode components.
[0004] According to one aspect of this application, a conveying device is provided for conveying a carrier for supporting an electrode assembly. The conveying device includes two conveying mechanisms, a supporting mechanism, and a control mechanism. The discharge directions of the two conveying mechanisms intersect, and the end of one conveying mechanism and the beginning of the other conveying mechanism define a corner area. Each conveying mechanism includes a plurality of conveying components spaced apart, the arrangement direction of which intersects the discharge direction of the conveying mechanism in which the plurality of conveying components are located. The supporting mechanism is located in the corner area and includes a supporting member and a rolling member. The supporting member has a supporting surface, and the rolling member is disposed on the supporting surface. The control mechanism is electrically connected to the two conveying mechanisms respectively and is used to control the conveying operation parameters of the two conveying mechanisms.
[0005] In the technical solution of this application embodiment, by configuring the conveying mechanism into multiple conveying components, the contact area between the conveying mechanism and the carrier can be reduced, thereby reducing the risk of impurity particles generated due to wear of the conveying mechanism and improving the overall cleanliness of the environment. By setting a support component in the corner area, the load can be distributed, which not only helps to improve the stability of the carrier but also helps to extend the service life of the conveying mechanism and further reduce the risk of impurity particles generated by the conveying mechanism. By configuring the support mechanism to include a support component and a rolling component, when the support mechanism supports the carrier, the sliding friction can be changed to rolling friction through the rolling component, which not only reduces the conveying resistance and facilitates conveying but also reduces frictional resistance and the risk of damage to the carrier during conveying. By controlling the conveying operation parameters of the two conveying mechanisms through the control mechanism, the carrier can pass through the corner area more smoothly through the coordination between the different conveying states of the two conveying mechanisms, thereby improving the stability of the carrier. Thus, this application embodiment improves the conveying quality by improving the overall cleanliness of the environment and improving the conveying stability in the corner area, thereby improving the quality of the electrode assembly. Furthermore, since the conveying mechanism is composed of multiple conveying components and the support is independently located in the corner area, it is convenient to perform individual maintenance on the conveying components that require maintenance and on the support, thereby improving the maintainability of the conveying device.
[0006] In some embodiments, the conveying component is configured to have a conveying structure.
[0007] This not only helps improve the smoothness of the conveying process, but also helps improve production efficiency and facilitates maintenance.
[0008] In some embodiments, the conveying assembly includes a plurality of conveying rollers, a guide roller, a tension roller, and a conveyor belt. The plurality of conveying rollers are arranged along the conveying path of the conveying assembly. The guide roller is located at the end of the conveying path and to one side of the last conveying roller. The tension roller is located to one side of the conveying path. The conveyor belt is wound around the plurality of conveying rollers and, via the guide roller, around the tension roller. The extending direction of the conveying path of the conveying assembly is parallel to the discharge direction of the conveying mechanism in which the conveying assembly is located.
[0009] Thus, by setting the conveying assembly to include multiple conveying rollers, steering rollers, tensioning rollers and conveyor belts, and using the steering rollers to place the tensioning rollers on one side of the conveying path of the conveying assembly, it is not only beneficial to increase the tension adjustment stroke and facilitate tension control, but also beneficial to improve the layout flexibility and maintainability of the conveying assembly.
[0010] In some embodiments, the conveying assembly further includes a blocking element, wherein the conveying roller is provided with a blocking element at at least one end along the axial direction of the conveying roller.
[0011] In this way, by setting up blocking components, the risk of conveyor belt deviation can be reduced, thereby improving the conveying stability and reliability of the conveying components.
[0012] In some embodiments, the conveying roller located at the beginning of the conveying path of the conveying assembly is configured as an electric roller.
[0013] This not only helps save space, improve control precision and maintainability, but also reduces the risk of generating impurity particles, thereby improving the overall cleanliness of the environment.
[0014] In some embodiments, in the same conveying mechanism, one conveying component is configured as the driving component, and the other conveying components are drive-connected to the driving component.
[0015] This not only allows all conveying components in the same conveying mechanism to be conveyed synchronously, but also reduces the number of drive components, simplifies the structure of the conveying mechanism, and further optimizes the spatial layout and saves costs.
[0016] In some embodiments, the conveying mechanism further includes a drive element electrically connected to the control mechanism. Within the same conveying mechanism, the drive element is drive-connected to multiple conveying components.
[0017] Thus, by setting up a driving component, it becomes easier to control the conveying of the conveying components through a control mechanism.
[0018] In some embodiments, the rolling element is configured as a universal ball bearing.
[0019] Thus, because universal ball bearings have omnidirectional rolling freedom, they can not only be used with two conveying mechanisms to improve the stability of the conveying load-bearing components, but also help to further reduce frictional resistance, thereby further reducing the risk of damage to the load-bearing components during the conveying process.
[0020] In some embodiments, the control mechanism includes two sensors and a controller. The two sensors and two conveying mechanisms are configured in a one-to-one correspondence. One sensor detects whether the carrier enters a corner area, and the other sensor detects whether the carrier leaves the corner area. The controller is electrically connected to each of the two sensors and controls the conveying operation parameters of the two conveying mechanisms based on the detection signals from the two sensors.
[0021] Thus, by setting two detection elements, the accuracy of the coordination between the two conveying mechanisms can be improved, which in turn helps the load-bearing components to pass through the corner area more smoothly and reliably.
[0022] In some embodiments, the controller includes two control units. The two control units and two detection units are configured in a one-to-one correspondence. The control units are electrically connected to their respective detection units, and the control units are used to control the conveying operation parameters of the corresponding conveying mechanism based on the detection signals from the corresponding detection units.
[0023] Thus, by setting up two control units, the corresponding conveying mechanisms can be controlled independently, facilitating independent start-up, shutdown, and state switching. This also helps to shorten troubleshooting time in case of malfunctions. Furthermore, this independent control method improves response speed and reduces lag errors in control signal execution, thereby enhancing conveying quality.
[0024] In some embodiments, the discharge directions of the two conveying mechanisms are perpendicular to each other.
[0025] This not only enables the transport of the carrier in two vertical directions, but also facilitates the operation of subsequent processes and improves operational convenience.
[0026] In some embodiments, along the conveying path of the conveying device, the upstream conveying mechanism is a first conveying mechanism, and the downstream conveying mechanism is a second conveying mechanism. The extension line of the conveying path of the innermost conveying component in the first conveying mechanism intersects the extension line of the conveying path of the innermost conveying component in the second conveying mechanism at a first intersection point. The extension line of the conveying path of the outermost conveying component in the first conveying mechanism intersects the extension line of the conveying path of the outermost conveying component in the second conveying mechanism at a second intersection point. The extension direction of the line connecting the first intersection point and the second intersection point intersects the discharge direction of the two conveying mechanisms, respectively. The first conveying mechanism and the second conveying mechanism are located on opposite sides of the line connecting the first intersection point and the second intersection point. The innermost conveying component is the conveying component located inside the corner area, and the outermost conveying component is the conveying component located outside the corner area.
[0027] This not only minimizes the change in the direction of movement of the carrier as it is transported from the first conveying mechanism to the second conveying mechanism, preventing sharp turns, but also allows the first and second conveying mechanisms to jointly support the carrier when it passes through corner areas. This improves the stability of the carrier as it passes through corner areas, thereby enhancing the conveying quality.
[0028] In some embodiments, the first conveying mechanism includes two conveying components; and / or, the second conveying mechanism includes two conveying components.
[0029] This not only meets the conveying requirements but also simplifies the structure of the conveying mechanism. This allows for a larger space in the corner area, which not only facilitates the installation of support mechanisms but also reduces the contact area between the load-bearing components and the various conveying mechanisms in the corner area, thereby further improving the stability of the load-bearing components as they pass through the corner.
[0030] In some embodiments, the control mechanism has a first mode. In the first mode, the control mechanism is configured to control one of two conveying mechanisms to perform conveying, while the other stops conveying.
[0031] Thus, in the first mode, when the carrier passes through the corner area, since the two conveying mechanisms do not convey at the same time, only one conveying mechanism conveys the carrier, which helps to improve the stability of the carrier passing through the corner area.
[0032] In some embodiments, along the conveying path of the conveying device, the upstream conveying mechanism is a first conveying mechanism, and the downstream conveying mechanism is a second conveying mechanism. In a first mode, the control mechanism is further configured to control the conveying speed of the first conveying mechanism to decelerate to zero at a first preset speed, and then control the conveying speed of the second conveying mechanism to accelerate from zero to a second preset speed.
[0033] Thus, in the first mode, by controlling the deceleration of the first conveyor mechanism and the acceleration of the second conveyor mechanism, it is beneficial to enable the carrier to pass through the corner area more smoothly.
[0034] In some embodiments, the control mechanism has a second mode. In the second mode, the control mechanism is configured to control one of the conveying mechanisms to perform conveying along the discharge direction of the one of the conveying mechanisms, while the other conveying mechanism performs conveying in the opposite direction to the discharge direction of the other of the conveying mechanisms.
[0035] Thus, in the second mode, when the carrier passes through the corner area, one of the conveying mechanisms can continue to transport the carrier so that it can pass through the corner area, while the other conveying mechanism can constrain the movement of the carrier, thereby making the process of the carrier passing through the corner area smoother and improving the conveying quality.
[0036] In some embodiments, the conveying operating parameters include conveying speed and conveying direction.
[0037] In this way, the smoothness of the load-bearing component passing through the corner area can be improved by flexibly controlling the conveying speed and direction of the conveying mechanism.
[0038] According to another aspect of this application, this application provides a battery production line including the conveying device in any of the above embodiments.
[0039] The battery production line also possesses the advantages of the conveying device in any of the above embodiments, and will not be elaborated further here.
[0040] In some embodiments, the battery production line includes a plurality of conveying components, all of which are spaced apart in a vertical direction. At least one conveying component is used to convey a carrier holding an electrode assembly, and at least one conveying component is used to convey a carrier not holding an electrode assembly. Of the plurality of conveying components, at least the conveying component used to convey the carrier holding the electrode assembly is configured as a conveying device.
[0041] This not only facilitates the automated input and output process of the carrier components, making the battery production process more automated and improving production efficiency, but also reduces the space occupied by the vertically spaced arrangement of the conveying components, making the battery production line more compact.
[0042] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0074] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of power battery applications, market demand is also constantly increasing.
[0075] In battery production, a conveyor system is typically used to efficiently transfer electrode components between different workstations. Since different workstations have equipment performing different tasks, the conveyor path is not always a straight line and may include turning areas to accommodate these different devices. When the conveyed electrode components pass through these turning areas, they are prone to collisions, which can damage them, causing them to become loose and difficult to fit into the casing, thus affecting the overall quality of the electrode components.
[0076] Therefore, in order to improve the quality of the electrode assembly, this application provides a conveying device that improves the conveying quality by changing the conveying structure, thereby improving the quality of the electrode assembly. Specifically, by configuring the conveying mechanism in the conveying device to include multiple conveying components, by setting a supporting mechanism in the corner area to cooperate with the conveying mechanism, and by using a control mechanism to control the conveying mechanism, the electrode assembly can pass through the corner area more smoothly, thereby improving the quality of the electrode assembly.
[0077] According to some embodiments of this application, please refer to Figures 1 to 4 , Figure 1 This is a three-dimensional structural diagram of the conveying device 100 in some embodiments of this application from one perspective. Figure 2 This is a three-dimensional structural diagram of the conveying device 100 in some embodiments of this application from another perspective. Figure 3 This is a three-dimensional structural diagram of the conveying device 100 in one conveying state in some embodiments of this application. Figure 4 This is a three-dimensional structural diagram of the conveying device 100 in some embodiments of the present application in another conveying state. The present application provides a conveying device 100 for conveying a carrier 300 for carrying an electrode assembly 220. The conveying device 100 includes two conveying mechanisms 110, a supporting mechanism 120, and a control mechanism 130.
[0078] The carrier 300 is a component used to support and transport the electrode assembly 220, serving as a support carrier for the electrode assembly 220 during processing, transfer, and testing. For example, using... Figure 3 and Figure 4 For example, the load-bearing component 300 can be a pallet.
[0079] Combined with reference Figure 5 , Figure 5 This is a partially exploded structural diagram of a battery cell 200 in some embodiments of this application. The electrode assembly 220 is the component in the battery cell 200 where the electrochemical reaction occurs. The electrode assembly 220 is mainly formed by stacking positive and negative electrode plates, and a separator is usually provided between the positive and negative electrode plates. A battery cell 200 refers to the smallest unit that makes up a battery device. Figure 5 As shown, the battery cell 200 includes a housing 210, electrode assemblies 220, and other functional components. The housing 210 is a component used to form the internal environment of the battery cell 200. The housing 210 may include a casing 211 and an end cap 212. The casing 211 is a component used to mate with the end cap 212 to form the internal environment of the battery cell 200. The housing 210 may contain one or more electrode assemblies 220. After the relevant operations on the electrode assemblies 220 are completed, they need to be installed into the housing 210.
[0080] For example, the battery cell 200 made using the electrode assembly 220 can be applied to a hybrid electric vehicle (HEV). Of course, it can also be applied to other devices, without specific limitations.
[0081] The discharge directions of the two conveying mechanisms 110 intersect, and the end of one conveying mechanism 110 and the beginning of the other conveying mechanism 110 define a corner area 101.
[0082] The conveying mechanism 110 is the main functional component of the conveying device 100. The conveying mechanism 110 refers to a modular component with conveying function, capable of directional carrying and movement of the carrier 300. The discharge direction of the conveying mechanism 110 refers to the direction in which the carrier 300 moves after being conveyed by the conveying carrier of the conveying mechanism 110 and leaving the effective conveying range of the conveying mechanism 110. The discharge directions of two conveying mechanisms 110 intersect, meaning that the discharge directions of the two conveying mechanisms 110 are different, thus allowing the carrier 300 to be conveyed in different directions. It should be noted that the conveying directions achievable by the conveying mechanism 110 include at least the direction consistent with its discharge direction. For example, when the conveying mechanism 110 has two completely opposite conveying directions, the conveying direction consistent with its discharge direction is the primary conveying direction, while the other opposite conveying direction is used to assist in controlling the conveying of the carrier 300.
[0083] For example, with Figure 1 and Figure 2 For example, this illustration shows a scenario where one conveying mechanism 110 has a discharge direction of the first direction F1, and the other conveying mechanism 110 has a discharge direction of the second direction F2. For instance, the first direction F1 and the second direction F2 intersect each other, and both the first direction F1 and the second direction F2 are horizontal.
[0084] The end of the conveying mechanism 110 refers to the end region where the conveyor 300 has been transported and is about to leave the carrying range of the conveying mechanism 110. The beginning of the conveying mechanism 110 refers to the end region where the conveyor 300 begins to enter the conveying mechanism 110 and first contacts the carrying range of the conveying mechanism 110. The corner area 101 is a transitional connection space defined by the end of one of the conveying mechanisms 110 and the beginning of the other conveying mechanism 110 through a preset layout. The corner area 101 does not have an independent power source and relies on the combined power of the two conveying mechanisms 110 or the power of either conveying mechanism 110 to transport the conveyor 300. The preset layout is determined based on the shape of both the end of one of the conveying mechanisms 110 and the beginning of the other conveying mechanism 110, as well as the discharge direction of the two conveying mechanisms 110.
[0085] It is understood that, with regard to the conveying device 100 as a whole, the conveying device 100 has a conveying path, and two conveying mechanisms 110 are arranged along the conveying path of the conveying device 100. Thus, one conveying mechanism 110 is located upstream of the other conveying mechanism 110. (Referring to reference...) Figures 1 to 4The upstream conveying mechanism 110 is the first conveying mechanism 110a, and the downstream conveying mechanism 110 is the second conveying mechanism 110b. The end of the first conveying mechanism 110a and the beginning of the second conveying mechanism 110b define a corner area 101.
[0086] Each conveying mechanism 110 includes a plurality of conveying components 111 arranged at intervals, and the arrangement direction of the plurality of conveying components 111 intersects with the discharge direction of the conveying mechanism 110 to which the plurality of conveying components 111 are located.
[0087] Combined with reference Figures 1 to 4 Each conveying mechanism 110 includes multiple conveying components 111. The conveying components 111 are the main functional parts constituting the conveying mechanism 110, and are modular components that can be independently manufactured, assembled, or replaced. The conveying components 111 in the same conveying mechanism 110 are connected mechanically, driven by power, or coordinated by signals to form the completed conveying components within the conveying mechanism 110. Since the arrangement direction of the multiple conveying components 111 intersects with the discharge direction of the conveying mechanism 110, the conveying components 111 in the same conveying mechanism 110 collectively achieve directional bearing, power drive, and attitude stability control of the load-bearing member 300.
[0088] For example, with Figures 1 to 4 For example, the conveying components 111 of the first conveying mechanism 110a are arranged at intervals along the second direction F2, and the conveying components 111 of the second conveying mechanism 110b are arranged at intervals along the first direction F1.
[0089] The support mechanism 120 is located in the corner area 101. The support mechanism 120 is a component used in the corner area 101 to cooperate with the conveying mechanism 110 to convey the carrier 300. The support mechanism 120 can provide auxiliary support for the carrier 300, thereby sharing the load of the conveying mechanism 110 when the carrier 300 passes through the corner area 101.
[0090] For example, in conjunction with reference Figure 6 and Figure 7 , Figure 6 for Figure 1 A magnified view of the structure at point A1. Figure 7 for Figure 2 A partially enlarged structural diagram at point A2 shows that the supporting mechanism 120 is located at the end of the first conveying mechanism 110a and the beginning of the second conveying mechanism 110b, defining the corner area 101. (Refer to reference...) Figure 3 and Figure 4 and in conjunction with reference Figure 8 and Figure 9 , Figure 8 for Figure 3 A magnified schematic diagram of the structure at point A3 in the middle.Figure 9 for Figure 4 The enlarged structural diagram at point A4 shows that during the process of the carrier 300 being transported from the first conveying mechanism 110a to the second conveying mechanism 110b, the carrier 300 will pass through the corner area 101. When passing through the corner area 101, the supporting mechanism 120 will cooperate with the first conveying mechanism 110a and the second conveying mechanism 110b to support the carrier 300.
[0091] Please continue to refer to Figures 6 to 8 The support mechanism 120 includes a support member 121 and a rolling member 122. The support member 121 has a support surface 1211, and the rolling member 122 is disposed on the support surface 1211. The support member 121 is the main component of the support mechanism 120. The support surface 1211 of the support member 121 faces the carrier member 300. The support surface 1211 provides a base for mounting the rolling member 122. The rolling member 122 is rotatable relative to the support member 121. Multiple rolling members 122 are provided, and all rolling members 122 can be arranged in an array, or in other regular or irregular patterns, without specific limitations.
[0092] For example, with Figure 6 and Figure 7 For example, the support member 121 is constructed as a plate-shaped member, and there are five rolling members 122. One rolling member 122 is located at the center of the support member 121, and the other four rolling members 122 are located at the four corners of the support member 121 respectively.
[0093] The control mechanism 130 is electrically connected to the two conveying mechanisms 110 respectively, and is used to control the conveying operation parameters of the two conveying mechanisms 110.
[0094] The control mechanism 130 refers to a control unit with signal acquisition, logic operation, and command output functions. The control mechanism 130 can establish independent electrical connections with the two conveying mechanisms 110 via wired or wireless means, and can send control commands to each conveying mechanism 110 respectively, thereby more precisely adjusting the conveying operation parameters of the corresponding conveying mechanism 110. For example, the conveying operation parameters include parameters such as conveying speed, conveying direction, start / stop timing, and acceleration, etc., which are not specifically limited here.
[0095] Therefore, by configuring the conveying mechanism 110 as multiple conveying components 111, the contact area between the conveying mechanism 110 and the carrier 300 can be reduced, thereby reducing the risk of impurity particles generated due to wear of the conveying mechanism 110 and improving the overall cleanliness of the environment. By providing a support member 121 in the corner area 101, the load can be distributed, which not only helps to improve the stability of the carrier 300, but also helps to extend the service life of the conveying mechanism 110 and further reduce the risk of impurity particles generated by the conveying mechanism 110. By configuring the support mechanism 120 to include a support member 121 and a rolling member 122, when the support mechanism 120 supports the carrier 300, the sliding friction can be converted into rolling friction by the rolling member 122, which not only reduces the conveying resistance and facilitates conveying, but also reduces frictional resistance and reduces the risk of damage to the carrier 300 during conveying. By controlling the conveying operation parameters of the two conveying mechanisms 110 through the control mechanism 130, the carrier 300 can pass through the corner area 101 more smoothly through the coordination between the different conveying states of the two conveying mechanisms 110, thereby improving the stability of the carrier 300. Thus, this embodiment improves the conveying quality and consequently the quality of the electrode assembly 220 by enhancing the overall cleanliness of the environment and improving the conveying stability of the corner area 101. Furthermore, since the conveying mechanism 110 is composed of multiple conveying components 111, and the support 121 is independently located in the corner area 101, it facilitates individual maintenance of the conveying components 111 and the support 121, thereby improving the maintainability of the conveying device 100.
[0096] It should be noted that, compared to conveying the carrier 300 by setting other mechanisms (such as lifting mechanisms) between the two conveying mechanisms 110, the conveying device 100 provided in this application embodiment can not only achieve a smoother conveying process, but also has better maintainability, safety and lower production costs.
[0097] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 , Figures 6 to 7 The conveying assembly 111 is configured with a conveying structure.
[0098] The belt conveyor structure is a structure in which the conveyor belt 1114 is the main carrier and power transmission medium. The conveyor belt 1114 directly carries and transmits power to the carrier 300. The conveyor belt 1114 is driven to circulate by a power drive unit (such as rollers). The friction between the conveyor belt 1114 and the carrier 300 drives the material to move along the required path, which can realize continuous and low-damage conveying.
[0099] Thus, because the belt conveyor structure bears load through surface contact, it helps to improve the smoothness of the conveying process. At the same time, because the belt conveyor mechanism 110 can achieve continuous cyclic movement and is a modular component, it helps to improve production efficiency and facilitate maintenance.
[0100] Of course, in other embodiments, the conveying component 111 may also be configured as a chain conveying structure, a roller conveying structure, etc., as long as the conveying component 111 can achieve the conveying function, and no specific limitation is made here.
[0101] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 , Figures 6 to 7 and in conjunction with reference Figure 10 , Figure 10 This is a three-dimensional structural diagram of the conveying component 111 in the conveying mechanism 110 of some embodiments of this application. The conveying component 111 includes multiple conveying rollers 1111, a guide roller 1112, a tension roller 1113, and a conveyor belt 1114. The multiple conveying rollers 1111 are arranged along the conveying path of the conveying component 111. The guide roller 1112 is located at the end of the conveying path of the conveying component 111 and is located on one side of the last conveying roller 1111. The tension roller 1113 is located on one side of the conveying path of the conveying component 111. The conveyor belt 1114 is wound around the multiple conveying rollers 1111 and wound around the tension roller 1113 via the guide roller 1112. The extending direction of the conveying path of the conveying component 111 is parallel to the discharge direction of the conveying mechanism 110 in which the conveying component 111 is located.
[0102] The conveyor belt 1114 is a flexible carrier in the belt conveyor structure that directly supports the carrier 300 and transmits power. It provides directional conveying power to the carrier 300 through continuous cyclic motion and achieves more uniform support through surface contact with the carrier 300.
[0103] The conveyor roller 1111 is a cylindrical roller in the belt conveyor structure. The conveyor roller 1111 is divided into driven and driven types. The driven type conveyor roller 1111 drives the conveyor belt 1114 to rotate cyclically via power output. The driven type conveyor roller 1111 rotates synchronously with the conveyor belt 1114, jointly supporting the conveyor belt 1114 and transmitting power, thus ensuring the smooth transport of the load-bearing component 300.
[0104] The steering roller 1112 is a cylindrical roller in the belt conveyor structure used to change the direction of movement of the conveyor belt 1114. It guides the movement of the conveyor belt 1114 by a preset installation angle, thereby changing the path.
[0105] The tension roller 1113 is a cylindrical roller in the belt conveyor structure used to adjust the tension of the conveyor belt 1114. It compensates for the slack of the conveyor belt 1114 by axial movement, so that the friction between the conveyor belt 1114 and the drive roller is sufficient, and at the same time it can help correct the deviation of the conveyor belt 1114.
[0106] Thus, by configuring the conveying assembly 111 to include multiple conveying rollers 1111, a guide roller 1112, a tension roller 1113, and a conveyor belt 1114, and by using the guide roller 1112 to position the tension roller 1113 on one side of the conveying path of the conveying assembly 111, it is not only beneficial to increase the tension adjustment stroke and facilitate tension control, but also beneficial to improve the layout flexibility and maintainability of the conveying assembly 111.
[0107] Based on some embodiments of this application, please continue to refer to Figure 10 and in conjunction with reference Figure 11 , Figure 11 for Figure 10 The enlarged structural diagram at point A5 shows that the conveying assembly 111 also includes a blocking member 1115, and the conveying roller 1111 has a blocking member 1115 at at least one end along the axial direction of the conveying roller 1111.
[0108] For example, with Figure 11 For example, a blocking member 1115 is provided at one end of the conveyor roller 1111 along the axial direction of the conveyor roller 1111.
[0109] Thus, by setting the blocking element 1115, the risk of conveyor belt 1114 deviating can be reduced, thereby improving the conveying stability and reliability of the conveying assembly 111.
[0110] According to some embodiments of this application, the conveying roller 1111 located at the beginning of the conveying path of the conveying assembly 111 is configured as an electric roller.
[0111] The beginning of the conveying path of the conveying assembly 111 refers to the starting point where the carrier 300 enters the conveying assembly 111, which is also the feeding end of the conveying assembly 111. The electric roller is an integrated power component that can both support the conveyor belt 1114 as the conveying roller 1111 and directly drive the conveyor belt 1114 to circulate by outputting torque through the built-in motor.
[0112] This not only helps save space, improve control precision and maintainability, but also reduces the risk of generating impurity particles, thereby improving the overall cleanliness of the environment.
[0113] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 , Figures 6 to 9In the same conveying mechanism 110, one of the conveying components 111 is configured as the driving component, and the other conveying components 111 are connected to the driving component in a driving connection.
[0114] For example, with Figures 1 to 4 , Figures 6 to 9 For example, one conveying component 111 drives the other conveying component 111 to rotate. (Refer to reference...) Figure 10 The conveying rollers 1111 at the beginning of the conveying paths of the two conveying components 111 are connected, and the connected conveying rollers 1111 can be Figure 10 The integrated structure shown.
[0115] This not only allows all conveying components 111 in the same conveying mechanism 110 to be conveyed synchronously, but also reduces the number of driving components, simplifies the structure of the conveying mechanism 110, and further optimizes the spatial layout and saves costs.
[0116] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 , Figures 6 to 9 The conveying mechanism 110 also includes a drive element 112 electrically connected to the control mechanism 130. In the same conveying mechanism 110, the drive element 112 is drive-connected to multiple conveying assemblies 111.
[0117] For example, the drive element 112 may be a drive motor. The drive element 112 is driven by the active conveyor roller 1111 of one of the conveying components 111, and the other conveying components 111 are driven by the one of the conveying components 111. In this way, multiple conveying components 111 can be driven by one drive element 112 in the same conveying mechanism 110.
[0118] Thus, by setting up the drive unit 112, it is advantageous to control the conveying of the conveying assembly 111 by the control mechanism 130.
[0119] Based on some embodiments of this application, please continue to refer to Figures 6 to 8 The rolling element 122 is configured as a universal ball bearing.
[0120] Thus, since the universal ball bearing has omnidirectional rolling freedom, it can not only cooperate with the two conveying mechanisms 110 to improve the stability of the conveying load 300, but also help to further reduce frictional resistance, thereby further reducing the risk of damage to the load 300 during the conveying process.
[0121] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 , Figures 6 to 9The control mechanism 130 includes two detection elements 131 and a controller 132. The two detection elements 131 and the two conveying mechanisms 110 are configured in a one-to-one correspondence. One detection element 131 is used to detect whether the carrier 300 enters the corner area 101, and the other detection element 131 is used to detect whether the carrier 300 leaves the corner area 101. The controller 132 is electrically connected to both detection elements 131, and the controller 132 is used to control the conveying operation parameters of the two conveying mechanisms 110 based on the detection signals from the two detection elements 131.
[0122] The detection element 131 can be a non-contact position sensor. For example, the detection element 131 can be a photoelectric sensor, a laser displacement sensor, or a proximity switch. The controller 132 is a control structure with signal acquisition, logic operation, and command output functions.
[0123] For example, with Figures 6 to 9 For example, when the carrier 300 enters the corner area 101 via the end of the first conveying mechanism 110a, the corresponding detection element 131 can detect the carrier 300 and send a relevant signal to the controller 132. When the carrier 300 enters the beginning of the second conveying mechanism 110b via the corner area 101, the corresponding detection element 131 can detect the carrier 300 and send a relevant signal to the controller 132. The controller 132 controls the first conveying mechanism 110a and the second conveying mechanism 110b to perform corresponding conveying actions according to the different detection signals received, thereby realizing the process of the carrier 300 moving from the first conveying mechanism 110a through the corner area 101 into the second conveying mechanism 110b.
[0124] For example, with Figures 6 to 9 For example, the detection element 131 is a through-beam photoelectric sensor. The detection element 131 consists of a transmitter and a receiver, which are arranged opposite to each other to form a continuous infrared / laser beam (refer to the through-beam beam 1310 shown in the diagram). When the carrier 300 passes through the through-beam beam 1310, the through-beam beam 1310 is blocked, and the receiver outputs a state switching signal. This allows for precise detection of the passage, presence, or position of the carrier 300, achieving non-contact, non-destructive detection.
[0125] Thus, by setting two detection elements 131, the position of the carrier 300 can be detected to determine whether the carrier 300 is in place, which helps to improve the accuracy of the coordination between the two conveying mechanisms 110, thereby helping the carrier 300 to pass through the corner area 101 more smoothly and reliably.
[0126] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 , Figure 6 and Figure 7The controller 132 includes two control components 1321. The two control components 1321 and the two detection components 131 are configured in a one-to-one correspondence. The control component 1321 is electrically connected to the corresponding detection component 131. The control component 1321 is used to control the conveying operation parameters of the corresponding conveying mechanism 110 according to the detection signal of the corresponding detection component 131.
[0127] For example, the control unit 1321 may be configured to have a speed regulation function and have multiple control levels, thereby realizing stepless speed regulation or graded speed regulation, without specific limitations.
[0128] Thus, by setting two control units 1321, not only can the corresponding conveying mechanism 110 be controlled independently, facilitating independent start-up, shutdown, and state switching of the conveying mechanism 110, but it also helps to shorten troubleshooting time in the event of a fault. Furthermore, this independent control method also helps to improve response speed and reduce lag errors in control signal execution, thereby improving conveying quality.
[0129] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 and in conjunction with reference Figure 12 , Figure 12 This is a top view of the conveying assembly 111 in some embodiments of this application, where the discharge directions of the two conveying mechanisms 110 are perpendicular to each other.
[0130] For example, the discharge direction of the first conveying mechanism 110a is the first direction F1, and the discharge direction of the second conveying mechanism 110b is the second direction F2. The first direction F1 and the second direction F2 are perpendicular to each other.
[0131] In this way, not only can the carrier 300 be transported in two vertical directions, but it also facilitates the operation of subsequent processes and improves the ease of operation.
[0132] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 , Figure 12Along the conveying path of the conveying device 100, the upstream conveying mechanism 110 is the first conveying mechanism 110a, and the downstream conveying mechanism 110 is the second conveying mechanism 110b. The extension line of the conveying path of the innermost conveying component 111 in the first conveying mechanism 110a intersects the extension line of the conveying path of the innermost conveying component 111 in the second conveying mechanism 110b at a first intersection point P1. The extension line of the conveying path of the outermost conveying component 111 in the first conveying mechanism 110a intersects the extension line of the conveying path of the outermost conveying component 111 in the second conveying mechanism 110b at a second intersection point P2. The extension direction of the line connecting the first intersection point P1 and the second intersection point P2 intersects the discharge direction of the two conveying mechanisms 110 respectively. The first conveying mechanism 110a and the second conveying mechanism 110b are located on both sides of the straight line C connecting the first intersection point P1 and the second intersection point P2. The innermost conveying component 111 is located inside the corner area 101, and the outermost conveying component 111 is located outside the corner area 101.
[0133] For example, with Figure 12 For example, Figure 12 The general arrangement of the conveying components 111 is briefly illustrated. The first conveying mechanism 110a and the second conveying mechanism 110b each include two conveying components 111. The innermost conveying component 111 in the first conveying mechanism 110a is the first conveying component 111a, and the innermost conveying component 111 in the second conveying mechanism 110b is the second conveying component 111b. The extension line of the conveying path of the first conveying component 111a is the first extension line L1, and the extension line of the conveying path of the second conveying component 111b is the second extension line L2. The first extension line L1 and the second extension line L2 intersect at a first point P1. The outermost conveying component 111 in the first conveying mechanism 110a is the third conveying component 111c, and the outermost conveying component 111 in the second conveying mechanism 110b is the fourth conveying component 111d. The extension line of the conveying path of the third conveying component 111c is the third extension line L3, and the extension line of the conveying path of the fourth conveying component 111d is the fourth extension line L4. The third extension line L3 and the fourth extension line L4 intersect at the second intersection point P2. The straight line connecting the first intersection point P1 and the second intersection point P2 is the straight line C.
[0134] For example, continue with Figure 12 For example, the length of the first conveying component 111a along the first direction F1 is less than the length of the third conveying component 111c along the first direction F1, and the length of the second conveying component 111b along the second direction F2 is less than the length of the fourth conveying component 111d along the second direction F2.
[0135] In this way, not only is the change in the direction of movement of the carrier 300 smaller during the process of being transported from the first conveying mechanism 110a to the second conveying mechanism 110b, and there will be no sharp turns, but the first conveying mechanism 110a and the second conveying mechanism 110b can also jointly support the carrier 300 when it passes through the corner area 101, which helps to improve the stability of the carrier 300 when passing through the corner area 101, thereby improving the conveying quality.
[0136] Of course, in some other embodiments, it is not necessary to use... Figure 12 The first conveying mechanism 110a and the second conveying mechanism 110b are arranged in the manner shown in the illustration. For example, the length of the third conveying component 111c along the first direction F1 is set to be the same as the length of the first conveying component 111a along the first direction F1, and the length of the second conveying component 111b along the second direction F2 is set to be the same as the length of the fourth conveying component 111d along the second direction F2, that is, the second conveying component 111b extends to the other side of the straight line C. No specific limitations are made here. It can be understood that the embodiments illustrated in this application are not limited to this. Figure 12 This arrangement not only facilitates the formation of a corner area 101 and the use of the corner area 101 to set up the supporting mechanism 120, but also facilitates the separate control of the first conveying mechanism 110a and the second conveying mechanism 110b. The first conveying mechanism 110a and the second conveying mechanism 110b can be used to jointly support the carrier 300 in the corner area 101, while minimizing the impact of the two on each other during the conveying process. This also makes it easier to smoothly control the movement of the carrier 300 at the corner.
[0137] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 2 , Figure 10 and Figure 12 The first conveying mechanism 110a includes two conveying components 111; and / or the second conveying mechanism 110b includes two conveying components 111.
[0138] In this way, not only can the conveying requirements be met, but the structure of the conveying mechanism 110 is also made simpler. In this way, the space of the corner area 101 can be set to be larger, which not only facilitates the installation of the support mechanism 120, but also helps to reduce the contact area between the load-bearing component 300 and each conveying mechanism 110 at the corner area 101, thereby further improving the stability of the load-bearing component 300 as it passes through the corner area 101.
[0139] Based on some embodiments of this application, please continue to refer to Figures 6 to 9 The control mechanism 130 has a first mode. In the first mode, the control mechanism 130 is configured to control one of the two conveying mechanisms 110 to perform conveying, while the other stops conveying.
[0140] That is, in the first mode, the first conveying mechanism 110a performs conveying, and the second conveying mechanism 110b stops conveying. Alternatively, the first conveying mechanism 110a stops conveying, and the second conveying mechanism 110b performs conveying.
[0141] Thus, in the first mode, when the carrier 300 passes through the corner area 101, since the two conveying mechanisms 110 do not convey at the same time, only one conveying mechanism 110 conveys the carrier 300, which helps to improve the stability of the carrier 300 passing through the corner area 101.
[0142] Based on some embodiments of this application, please continue to refer to Figures 6 to 9 Along the conveying path of the conveying device 100, the upstream conveying mechanism 110 is the first conveying mechanism 110a, and the downstream conveying mechanism 110 is the second conveying mechanism 110b. In the first mode, the control mechanism 130 is also configured to control the conveying speed of the first conveying mechanism 110a to decelerate to zero at a first preset speed, and then control the conveying speed of the second conveying mechanism 110b to accelerate from zero to a second preset speed.
[0143] For example, the first preset speed and the second preset speed may be the same or different, and no specific restrictions are imposed here.
[0144] For example, the control mechanism 130 can be used to control the conveying speed of the first conveying mechanism 110a to linearly decelerate to zero at a first preset speed, and then control the conveying speed of the second conveying mechanism 110b to linearly accelerate from zero to a second preset speed. This makes the change in conveying speed smoother, which helps to improve the stability of the conveying carrier 300.
[0145] For example, in conjunction with reference Figures 6 to 9 When the carrier 300 enters the corner area 101 via the end of the first conveyor 110a, the corresponding detector 131 detects the carrier 300 and sends a relevant signal to the controller 132. The controller 132 controls the first conveyor 110a to decelerate linearly to zero from its current speed. At this time, the carrier 300 enters the beginning of the second conveyor 110b via the corner area 101. The corresponding detector 131 detects the carrier 300 and sends a relevant signal to the controller 132. The controller 132 controls the second conveyor 110b to accelerate linearly from zero to the required speed.
[0146] Thus, in the first mode, by controlling the first conveying mechanism 110a to decelerate and the second conveying mechanism 110b to accelerate, it is beneficial to enable the carrier 300 to pass through the corner area 101 more smoothly.
[0147] Based on some embodiments of this application, please continue to refer toFigures 6 to 9 The control mechanism 130 has a second mode. In the second mode, the control mechanism 130 is configured to control one of the conveying mechanisms 110 to perform conveying along the discharge direction of the one of the conveying mechanisms 110, while the other conveying mechanism 110 performs conveying in the opposite direction to the discharge direction of the other conveying mechanism 110.
[0148] For example, in conjunction with reference Figures 6 to 9 When the carrier 300 enters the corner area 101 via the end of the first conveying mechanism 110a, the corresponding detection element 131 detects the carrier 300 and sends a relevant signal to the controller 132. The controller 132 controls the first conveying mechanism 110a to gradually decelerate at the current speed and controls the second conveying mechanism 110b to perform a conveying direction opposite to the discharge direction. At this time, under the combined action of the first conveying mechanism 110a and the second conveying mechanism 110b, the carrier 300 more smoothly enters the beginning of the second conveying mechanism 110b via the corner area 101. The corresponding detection element 131 detects the carrier 300 and sends a relevant signal to the controller 132. The controller 132 controls the second conveying mechanism 110b to perform a conveying direction in the same direction as the discharge direction and controls the first conveying mechanism 110a to perform a conveying direction opposite to the discharge direction. At this time, under the combined action of the first conveying mechanism 110a and the second conveying mechanism 110b, the carrier 300 more smoothly and completely enters the second conveying mechanism 110b.
[0149] In the control method shown above, it is equivalent to both the first conveying mechanism 110a and the second conveying mechanism 110b being able to rotate forward and reverse, thereby flexibly realizing different conveying modes, without making specific restrictions here.
[0150] Thus, in the second mode, when the carrier 300 passes through the corner area 101, one of the conveying mechanisms 110 can continue to convey the carrier 300 so that the carrier 300 can pass through the corner area 101, while the other conveying mechanism 110 can constrain the movement of the carrier 300, thereby making the process of the carrier 300 passing through the corner area 101 smoother and improving the conveying quality.
[0151] Therefore, through the first and second modes illustrated above, the corresponding conveying mechanisms 110 can be flexibly controlled to achieve different conveying methods. Simultaneously, through the cooperation of the two conveying mechanisms 110 and the auxiliary support of the supporting mechanism 120, the carrier 300 can pass through the corner area 101 more smoothly, thereby improving the conveying quality. Furthermore, in this process, the improved smoothness of the conveying process results in a more precise conveying position for the carrier 300. It should be noted that the control method of the conveying speed of each conveying mechanism 110 is not specifically limited in different conveying methods. For example, the conveying speed can be selected in increments, or it can gradually decrease or increase linearly; no specific limitations are imposed here.
[0152] According to some embodiments of this application, the conveying operation parameters include conveying speed and conveying direction.
[0153] In this way, the smoothness of the carrier 300 passing through the corner area 101 can be improved by flexibly controlling the conveying speed and conveying direction of the conveying mechanism 110.
[0154] According to some embodiments of this application, this application provides a battery production line, including the conveying device 100 in any of the above embodiments.
[0155] The battery production line also possesses the advantages of the conveying device 100 in any of the above embodiments, and will not be repeated here.
[0156] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 The battery production line includes multiple conveying components, all of which are spaced apart vertically. At least one conveying component is used to convey a carrier 300 carrying an electrode assembly 220, and at least one conveying component is used to convey a carrier 300 not carrying an electrode assembly 220. Among these multiple conveying components, at least the conveying component used to convey the carrier 300 carrying the electrode assembly 220 is configured as a conveying device 100.
[0157] For example, with Figures 1 to 4 For example, the illustration shows a scenario where two conveying components are provided, and both are configured as conveying devices 100. The two conveying devices 100 are arranged at intervals along a third direction F3, with the first direction F1, the second direction F2, and the third direction F3 being perpendicular to each other. The conveying device 100 located on the top side is used to convey the carrier 300 carrying the electrode assembly 220, and the conveying device 100 located on the bottom side is used to convey the carrier 300 not carrying the electrode assembly 220. Figures 1 to 4 In the diagram, for ease of illustration of the relevant structures, the supporting mechanism 120 is not shown in the bottom conveying device 100.
[0158] For example, withFigures 1 to 4 For example, the conveying device 100 also includes a frame 140, and the conveying mechanism 110, the supporting mechanism 120 and the control mechanism 130 are all located on the frame 140. The frames 140 of the two conveying devices 100 are connected. The frames 140 of the two conveying devices 100 can be an integral structure, and no specific limitation is made here.
[0159] For example, the battery production line also includes a connecting mechanism that connects to two conveying devices 100. For example, the connecting mechanism can be a lifting mechanism or a jacking mechanism, which can assist in transferring the carrier 300 from one conveying device 100 to another conveying device 100, thereby achieving automated continuous production.
[0160] This not only facilitates the input and output process of the automated carrier 300, making the battery production process more automated and improving production efficiency, but also reduces the space occupied by the vertically spaced conveying components, making the battery production line more compact.
[0161] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
