Description

Technical Field

[0001] The utility model relates to the technical field of battery core processing, in particular to a battery core transmission system. Background Art

[0002] With the continuous development and refinement of lithium battery production technology, assembly and baking processes have become an indispensable part of the lithium battery production process. In the traditional lithium battery production process, the core needs to be assembled and welded, and then put into the shell to form a battery cell. The battery cell is helium-tested, and the battery cell that has completed the helium test enters the baking equipment through the conveyor equipment. After the baking and drying is completed, it is then conveyed to the liquid injection equipment through the conveyor equipment.

[0003] Among them, after the battery cells have been inspected by the helium inspection machine, they need to be transported to the baking equipment through the transmission system. The current method is to use a robot to grab the battery cells that have been inspected by the helium inspection and place them in the transmission basket. After the transmission basket is full, the transmission basket is transported to the loading place of the drying equipment. The robot located at the loading place of the drying equipment takes out the battery cells in the transmission basket and places the taken-out battery cells in the drying equipment to complete the drying. However, the use of this transmission system will take up a large space and have low production efficiency.

[0004] Therefore, how to improve the material transmission efficiency between the primary helium detector and the drying equipment and reduce the space occupied by the transmission system has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The main purpose of the utility model is to provide a battery cell transmission system, aiming to improve the transmission efficiency of materials between a primary helium detector and a drying device and reduce the space occupied by the transmission system.

[0006] In order to achieve the above object, the utility model proposes a battery cell transmission system, comprising:

[0007] A main conveying device with at least one first conveying channel for conveying materials to the next workstation;

[0008] At least one branch conveyor, provided on one side of the main conveyor, for conveying materials output from a previous workstation; and

[0009] The rotating device is arranged at the intersection of the main conveying device and the branch conveying device, and is used for conveying the materials on the branch conveying device to the main conveying device.

[0010] The system can achieve efficient transmission of battery cells through the coordinated work of the main conveyor and the branch conveyor. The introduction of the rotating device makes the transfer of battery cells between different conveyor devices smoother, reducing pauses and jams during the transmission process. The setting of the branch conveyor enables the system to flexibly respond to the transmission needs between different workstations. Whether it is a linear production line or a circular production line, the system can achieve smooth transmission of battery cells by adjusting the layout of the conveyor and the angle of the rotating device. Through reasonable layout design, the main conveyor and the branch conveyor can achieve efficient transmission in a limited space. The setting of the rotating device enables the system to realize the steering and transfer of battery cells in a smaller space, saving the floor space of the production line.

[0011] In one embodiment of the present application, the rotating device comprises:

[0012] Swivel base;

[0013] A supporting platform connected to the rotating base; and

[0014] The first pull belt is arranged on the supporting platform. When the rotating base drives the input end of the first pull belt toward the output end of the branch transmission device or the output end of the main transmission device adjacent thereto, the first pull belt can input and temporarily store materials on the branch transmission device or the main transmission device. When the rotating base drives the input end of the first pull belt toward the input end of the main transmission device, the first pull belt can output the temporarily stored materials to the main transmission device.

[0015] The system achieves efficient transmission and temporary storage of battery cells through a rotating device. The first pull belt can flexibly transfer battery cells between the branch conveyor and the main conveyor, improving the transmission efficiency. The introduction of the temporary storage function enables the system to respond to emergencies during the transmission process. For example, when the main conveyor is temporarily unable to receive the battery cells, the first pull belt can temporarily store the battery cells, avoiding pauses and jams during the transmission process. The rotating base of the rotating device controls its rotation angle through the drive motor, which can be flexibly adjusted according to the needs of the production line. Whether it is a linear production line or a circular production line, the system can achieve smooth transmission of battery cells by adjusting the angle of the rotating device.

[0016] In one embodiment of the present application, the rotating device further includes:

[0017] A first U-shaped gantry connected to the support platform, wherein a first free end of the first U-shaped gantry is connected to one side of the length direction of the first drawstring, and a second free end of the first U-shaped gantry is connected to the other side of the length direction of the first drawstring;

[0018] The first U-shaped gantry is provided with a dividing piece for dividing the first pull belt into at least one second transmission channel.

[0019] The first U-shaped gantry divides the first pull belt into multiple second transmission channels through a dividing piece, so that the system can transmit multiple battery cells at the same time, thereby improving transmission efficiency and flexibility.

[0020] In one embodiment of the present application, a first roller is provided on the dividing piece along the length direction to contact with the material to reduce the friction between the material and the dividing piece.

[0021] The first roller on the dividing piece contacts the material, reducing the friction between the material and the dividing piece, thereby reducing the resistance during transmission and improving the transmission efficiency. The introduction of the first roller not only reduces friction, but also guides and stabilizes the material, ensuring that the material remains stable during transmission and reducing deviation and jamming.

[0022] In one embodiment of the present application, the number of the first transmission channels is equal to the number of the second transmission channels.

[0023] The same amount of material on each conveyor channel can avoid overloading some channels while other channels are idle. Even load distribution ensures that all channels are running efficiently, maximizing the overall transmission efficiency of the system. At the same time, the system can be more easily modularized, with each module including the same number of conveyor channels, which is easy to expand and upgrade.

[0024] In one embodiment of the present application, the branch conveying device is provided with a first stopper for closing the output end of the branch conveying device when the first drawstring input end is not facing the output end of the branch conveying device.

[0025] The first stopper ensures that the material can enter the branch conveyor only when the first draw belt input end is aligned, thereby ensuring the correct guidance of the material. Ensure that the material is transmitted along the predetermined path, improve the accuracy and reliability of the transmission process, prevent misoperation caused by misalignment of the transmission path, and improve the operational consistency of the system.

[0026] In one embodiment of the present application, a second stopper is provided on the output end of the main conveying device facing the rotating device when the first drawstring input end is not facing the output end of the main conveying device adjacent thereto, for closing the second stopper on the main conveying device facing the output end of the rotating device.

[0027] The second stopper ensures that the material can enter the output end of the main conveyor device adjacent to it only when the input end of the first pull belt is aligned, thereby ensuring the correct guidance of the material. Ensure that the material is transmitted along the predetermined path, improve the accuracy and reliability of the transmission process, prevent misoperation caused by misalignment of the transmission path, and improve the operational consistency of the system.

[0028] In one embodiment of the present application, second rollers are provided on both sides of the first conveying channel for contacting the material to reduce the friction between the material and the inner wall of the first conveying channel.

[0029] The friction between the material and the inner wall of the first conveying channel can be effectively reduced, thereby protecting the material.

[0030] In one embodiment of the present application, the number of the first transmission channels is four.

[0031] Four concurrent channels can transmit four materials at the same time, greatly improving production efficiency.

[0032] In one embodiment of the present application, a robot capable of removing materials from the main conveying device is provided at the output end of the main conveying device away from the rotating device.

[0033] A manipulator capable of removing materials from the main conveying device is disposed at the output end of the main conveying device away from the rotating device.

[0034] By adopting the above technical solution, the system can realize efficient transmission of battery cells through the coordinated work of the main conveyor and the branch conveyor. The introduction of the rotating device makes the transfer of battery cells between different conveyor devices smoother, reducing the pauses and jams during the transmission process. The setting of the branch conveyor enables the system to flexibly respond to the transmission needs between different workstations. Whether it is a linear production line or a circular production line, the system can realize the smooth transmission of battery cells by adjusting the layout of the conveyor and the angle of the rotating device.

[0039] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the utility model and do not constitute a limitation on the utility model.

[0040] like Figure 1 to Figure 2 As shown, in order to achieve the above purpose, the utility model proposes a battery cell transmission system, including:

[0041] A main conveying device 10 with at least one first conveying channel 13 for conveying materials to the next station;

[0042] At least one branch conveyor 20, disposed on one side of the main conveyor 10, for conveying materials output from a previous workstation; and

[0043] The rotating device 30 is disposed at the intersection of the main conveying device 10 and the branch conveying device 20 , and is used to convey the materials on the branch conveying device 20 to the main conveying device 10 .

[0044] Specifically, the main conveyor 10 is used to transfer the battery cell from the previous station to the next station. The main conveyor 10 includes at least one first conveying channel 13, and the bottom of the first conveying channel 13 is a conveyor belt, which can continuously and stably convey materials. The conveyor belt can be made of wear-resistant material to ensure its durability for long-term operation. The speed of the conveyor belt can be adjusted to adapt to the production rhythm of different stations.

[0045] The branch conveyor 20 is arranged on one side of the main conveyor 10, and is used to transfer the battery cells output from the previous station to the main conveyor 10. The length direction of the branch conveyor 20 is perpendicular to the length direction of the main conveyor 10. In order to ensure that the battery cells can be smoothly transferred from the branch conveyor 20 to the main conveyor 10, the conveyor belt speed of the branch conveyor 20 is synchronized with the speed of the main conveyor 10. It is conceivable that the conveyor belt speed of the branch conveyor 20 and the conveyor belt of the main conveyor 10 can be differentiated to achieve the adjustment of the production rhythm.

[0046] The rotating device 30 is arranged at the intersection of the main conveying device 10 and the branch conveying device 20, and its function is to transfer the battery cells on the branch conveying device 20 to the main conveying device 10. The rotating device 30 generally includes a rotating base and a drive motor. The rotating base can rotate a certain angle on the horizontal plane, generally 90 degrees or 180 degrees, to achieve the steering and transfer of the battery cells. The drive motor can ensure that the rotation angle and speed of the rotating base meet the requirements through a precise control system.

[0047] The main conveyor 10 is usually arranged in the center of the production line, and the branch conveyor 20 is arranged on one side thereof.

[0048] The end of the branch conveyor 20 is connected to the side of the main conveyor 10 to ensure that the battery cells can be smoothly transferred from the branch conveyor 20 to the main conveyor 10. To achieve this, the rotating device 30 needs to split the main conveyor 10, and the branch conveyor 20 is located on one side of the rotating device 30.

[0049] By adopting the above technical solution, the system can realize efficient transmission of battery cells through the coordinated work of the main conveyor 10 and the branch conveyor 20. The introduction of the rotating device 30 makes the transfer of battery cells between different conveyor devices smoother, reducing the pauses and jams during the transmission process. The setting of the branch conveyor 20 enables the system to flexibly respond to the transmission needs between different workstations. Whether it is a linear production line or a circular production line, the system can realize the smooth transmission of battery cells by adjusting the layout of the conveyor and the angle of the rotating device 30. Through reasonable layout design, the main conveyor 10 and the branch conveyor 20 can realize efficient transmission in a limited space. The setting of the rotating device 30 enables the system to realize the steering and transfer of battery cells in a smaller space, saving the floor space of the production line.

[0050] In one embodiment of the present application, the rotating device 30 includes:

[0051] Swivel base;

[0052] A supporting platform connected to the rotating base; and

[0053] The first pull belt is arranged on the supporting platform. When the rotating base drives the input end of the first pull belt toward the output end of the branch transmission device or the output end of the main transmission device 10 adjacent thereto, the first pull belt can input and temporarily store the materials on the branch transmission device or the main transmission device 10. When the rotating base drives the input end of the first pull belt toward the input end of the main transmission device 10, the first pull belt can output the temporarily stored materials to the main transmission device 10.

[0054] Specifically, the rotating base provides a stable rotating base. The rotating base is made of high-strength materials, such as aluminum alloy materials, alloy steel materials, etc., and can withstand the force generated during the rotation process. The rotating base is built with a drive motor and a rotating shaft. Through the control of the drive motor, the rotating base can be accurately rotated on a horizontal plane, and the rotation angle is 90 degrees or 180 degrees.

[0055] The support platform is installed on the rotating base and is used to carry the main platform of the battery cell. The support platform is connected to the rotating base and can rotate with the rotating base.

[0056] The first pull belt is a conveying device on the supporting platform, and its main function is to temporarily store the battery cells output from the branch conveying device 20 or the main conveying device 10, and then convey the battery cells to the main conveying device 10 as needed.

[0057] When the rotating base drives the input end of the first pull belt toward the output end of the branch conveyor 20 or the output end of the adjacent main conveyor 10, the first pull belt can input and temporarily store the battery cells from these devices. When the rotating base drives the input end of the first pull belt toward the input end of the main conveyor 10, the first pull belt outputs the temporarily stored battery cells to the main conveyor 10.

[0058] By adopting the above technical solution, the system realizes the efficient transmission and temporary storage functions of the battery cells through the rotating device 30. The first pull belt can flexibly transfer the battery cells between the branch conveyor 20 and the main conveyor 10, thereby improving the transmission efficiency. The introduction of the temporary storage function enables the system to cope with emergencies during the transmission process. For example, when the main conveyor 10 is temporarily unable to receive the battery cells, the first pull belt can temporarily store the battery cells, thereby avoiding pauses and jams during the transmission process. The rotating base of the rotating device 30 controls its rotation angle through the driving motor, and can be flexibly adjusted according to the needs of the production line. Whether it is a linear production line or a circular production line, the system can achieve smooth transmission of the battery cells by adjusting the angle of the rotating device 30.

[0059] In one embodiment of the present application, the rotating device 30 further includes:

[0060] A first U-shaped gantry connected to the support platform, wherein a first free end of the first U-shaped gantry is connected to one side of the length direction of the first drawstring, and a second free end of the first U-shaped gantry is connected to the other side of the length direction of the first drawstring;

[0061] The first U-shaped gantry is provided with a dividing piece for dividing the first pull belt into at least one second transmission channel.

[0062] Specifically, the first U-shaped gantry is connected to the supporting platform, and its main function is to provide additional structural support and divide the first pull belt into at least one second transmission channel through a dividing piece.

[0063] The first free end of the first U-shaped gantry is connected to one side of the first drawstring in the length direction, and the second free end is connected to the other side of the first drawstring in the length direction, forming a U-shaped structure that spans the first drawstring. It can be imagined that there is no direct contact between the first U-shaped gantry and the first drawstring, thereby ensuring the stable operation of the first drawstring.

[0064] The first U-shaped gantry is provided with a dividing piece for dividing the first pull belt into at least one second transmission channel. The dividing piece can be a fixed partition or an adjustable baffle, which is used to divide the transmission path on the first pull belt into multiple channels so as to simultaneously transmit multiple battery cells.

[0065] By adopting the above technical solution, the first U-shaped gantry divides the first pull belt into multiple second transmission channels through the dividing piece, so that the system can transmit multiple battery cells at the same time, thereby improving the transmission efficiency and flexibility.

[0066] In one embodiment of the present application, a first roller is provided on the dividing piece along the length direction to contact with the material to reduce the friction between the material and the dividing piece.

[0067] Specifically, the first U-shaped gantry is connected to the supporting platform to provide structural support, and a dividing piece is arranged to divide the first pull belt into a plurality of transmission channels.

[0068] The dividing piece is installed on the first U-shaped gantry to divide the first pull belt into at least one second transmission channel. The first roller is installed on the dividing piece, arranged along the length direction of the dividing piece, and contacts with the material to reduce friction.

[0069] With the above technical solution, the first roller on the dividing piece contacts the material, reducing the friction between the material and the dividing piece, thereby reducing the resistance during the transmission process and improving the transmission efficiency. The introduction of the first roller not only reduces the friction, but also plays a role in guiding and stabilizing the material, ensuring that the material remains stable during the transmission process and reducing the deviation and jamming phenomenon.

[0070] In one embodiment of the present application, the number of the first transmission channels is equal to the number of the second transmission channels.

[0071] With the above technical solution, the same amount of materials are placed on each conveying channel, which can avoid the situation where some channels are overloaded while other channels are idle. The uniform load distribution ensures that all channels are running efficiently, maximizing the overall transmission efficiency of the system. At the same time, the system can be more easily modularized, with each module including the same number of conveying channels, which is convenient for expansion and upgrading.

[0072] In one embodiment of the present application, the branch conveying device 20 is provided with a first stopper for closing the output end of the branch conveying device 20 when the first drawstring input end is not facing the output end of the branch conveying device 20 .

[0073] By adopting the above technical solution, the first stopper ensures that the material can enter the branch conveyor 20 only when the first draw belt input end is aligned, thereby ensuring the correct guidance of the material. It ensures that the material is transmitted along the predetermined path, improves the accuracy and reliability of the transmission process, prevents erroneous operation caused by misalignment of the transmission path, and improves the operational consistency of the system.

[0074] In one embodiment of the present application, a second stopper 12 is provided on the output end of the main conveying device 10 facing the rotating device 30 for closing the output end of the main conveying device 10 facing the output end of the rotating device 30 when the first drawstring input end is not facing the output end of the main conveying device 10 adjacent thereto.

[0075] By adopting the above technical solution, the second stopper 12 ensures that the material can enter the output end of the main conveying device 10 adjacent thereto only when the input end of the first draw belt is aligned, thereby ensuring the correct guidance of the material. It ensures that the material is transmitted along the predetermined path, improves the accuracy and reliability of the transmission process, prevents erroneous operation caused by misalignment of the transmission path, and improves the operational consistency of the system.

[0076] In one embodiment of the present application, second rollers 11 are disposed on both sides of the first conveying channel 13 to contact the material to reduce the friction between the material and the inner wall of the first conveying channel 13 .

[0077] By adopting the above technical solution, the friction between the material and the inner wall of the first conveying channel 13 can be effectively reduced, thereby protecting the material.

[0078] In one embodiment of the present application, the number of the first transmission channels 13 is four.

[0079] By adopting the above technical solution, four concurrent channels can transmit four materials at the same time, greatly improving production efficiency.

[0080] In one embodiment of the present application, a robot capable of removing materials from the main conveying device 10 is provided at an output end away from the rotating device 30 .

[0081] By adopting the above technical solution, a manipulator is provided to facilitate unloading operations on the materials on the main conveying device 10, thereby improving the efficiency of unloading, eliminating the need for manual intervention, and having a simple structure and being easy to implement.
