[0008] The drive mechanism is mounted on the base.

[0009] At least two transmission mechanisms are connected to the drive mechanism. The transmission mechanisms are used to receive the battery cells transmitted by each feeding device along a second direction, which has an angle with the first direction.

[0017] The lead screw is rotatably connected to the base in a first direction, and the lead screw is connected to the drive end of the first drive member. The support member is rotatably connected to the lead screw.

[0018] A sliding rod is connected to the base along a first direction, and a support member is slidably connected to the sliding rod.

[0019] The first driving element drives the lead screw to rotate, thereby causing the support element and the transmission mechanism to translate along the first direction.

[0020] In one possible implementation, the number of support members is at least two, and the support members are arranged sequentially at intervals.

[0021] It also includes connectors, which are attached to the various support components, and the transmission mechanism is attached to the connectors.

[0027] The second driving component is mounted on the bracket and connected to the vacuum conveyor belt. The second driving component is used to drive the vacuum conveyor belt to move.

[0028] The negative pressure component is connected to the vacuum chamber and is used to generate negative pressure.

[0029] In one possible implementation, the transmission mechanism further includes:

[0030] The sensor, mounted on a bracket, is used to detect whether there are battery cells on the vacuum conveyor belt.

[0031] The controller is communicatively connected to the sensor, the negative pressure component, and the second drive component. When the sensor detects a battery cell on the vacuum conveyor belt, the controller controls the negative pressure component to generate negative pressure so that the vacuum conveyor belt can attract the battery cell, and controls the second drive component to stop running.

[0032] In one possible implementation, the negative pressure element includes:

[0033] Vacuum pipe, which is connected to the vacuum chamber;

[0041] In one possible implementation, the transfer device includes a base disposed on one side of each feeding device along a first direction, and the length of the base along the first direction is greater than the total length of each feeding device along the first direction.

[0042] The transfer device and battery production system provided in this application embodiment include a transfer device with a base extending along a first direction and positioned on one side of multiple feeding devices of the battery production system arranged sequentially along the first direction, such that the base and the multiple feeding devices are arranged in the same direction. A drive mechanism and at least two transmission mechanisms are provided. The drive mechanism is mounted on the base, and the at least two transmission mechanisms are connected to the drive mechanism. The drive mechanism drives the transmission mechanisms to translate, allowing each transmission mechanism to move from the feeding device to the unloading device of the battery production system. The drive mechanism can drive the transmission mechanisms to translate along the first direction, ensuring that the extension direction of the base and the arrangement direction of the feeding devices are the same as the translation direction of the transmission mechanisms. This facilitates the transmission mechanisms receiving battery cells transported by each feeding device along a second direction, and each transmission mechanism can sequentially transport the received battery cells to the unloading device, thus achieving battery cell transfer. Furthermore, the at least two transmission mechanisms can improve the battery cell transfer efficiency. During the battery cell transfer process, each transmission mechanism always translates along the first direction, minimizing vibration and reducing the risk of damage to the battery cells on each transmission mechanism.

[0061] During the battery production process, the battery cells that form the battery are baked by a baking device and then transferred to a screen printing device for screen printing in sequence via a feeding device, a transfer device, and a discharging device.

[0062] This application provides a battery production system. Figure 1 This is a schematic diagram of the battery production system provided in an embodiment of this application.

[0063] Please see Figure 1 The battery production system includes: multiple components along a first direction (e.g., ... Figure 1 The feeding devices 20 are arranged sequentially at intervals in the X direction (in the middle), and the feeding devices 20 are used to transport the battery cells 40; the transfer devices 10 are arranged on one side of each feeding device 20, and the transfer devices 10 are used to receive and transport the battery cells 40 transported by each feeding device 20; the unloading devices 30 are arranged on one side of the transfer devices 10, and the unloading devices 30 are used to receive and transport the battery cells 40 transported by the transfer devices 10.

[0064] In this embodiment, by setting up a transfer device 10, the transfer of the battery cell 40 from one process to another can be realized.

[0065] It should be noted that the embodiments of this application do not specifically limit the application scenarios of the feeding device 20, the transfer device 10 and the unloading device 30. For example, the feeding device 20, the transfer device 10 and the unloading device 30 can be set between the cleaning device and the baking device in the battery production system, or between the baking device and the screen printing device, or between the screen printing device and the sorting and testing device.

[0066] Understandable Figure 1 The diagram only schematically illustrates some of the components included in a battery production system; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, battery production systems can also include, compared to... Figure 1 More or fewer parts.

[0067] In some embodiments (not shown in the figures of this embodiment), the battery production system further includes: a baking device for baking the battery cells 40, a feeding device 20 connected to the baking device for receiving the battery cells 40 after baking; and a screen printing device connected to the unloading device 30 for screen printing the battery cells 40 transmitted by the unloading device 30.

[0068] In this embodiment, the feeding device 20, the transfer device 10, and the unloading device 30 are arranged between the baking device and the screen printing device. The transfer device 10 can be used to transfer the battery cells 40 that have been baked by the baking device.

[0069] Related technology provides a transfer device, which includes a robotic arm and a suction cup mechanism disposed on the robotic arm. The suction cup mechanism is used to adsorb battery cells, and the robotic arm is used to transfer the battery cells from a loading device to a unloading device.

[0070] However, the significant vibrations generated during the operation of the robotic arm can easily damage the battery cells.

[0071] To address the aforementioned technical problems, this application provides a transfer device 10. Figure 2 This is a partial structural diagram of the transfer device 10 in the battery production system. Figure 3 This is a schematic diagram of the connection between the transfer mechanism 300 and the connector 400 in the transfer device 10 of the battery production system. Figure 4 for Figure 3 A schematic diagram of the connection between the central support 310 and the conveyor belt assembly 320; Figure 5 for Figure 3 A schematic diagram of the structure of the conveyor belt assembly.

[0072] Specifically, please refer to Figures 1 to 3 The transfer device 10 includes: a base 100, the base 100 being arranged along a first direction (e.g., Figure 1 Extending in the X direction, a base 100 is used to be mounted on one side of a plurality of feeding devices 20 of a battery production system arranged sequentially at intervals along the first direction X; a drive mechanism 200 is mounted on the base 100; at least two transmission mechanisms 300 are connected to the drive mechanism 200, and the transmission mechanisms 300 are used to respectively receive and transmit the feeds from each feeding device 20 along the second direction (e.g., X-axis). Figure 1 The battery cell 40 is transmitted in the Y direction, and the second direction Y has an angle with the first direction X; the driving mechanism 200 drives the transmission mechanism 300 to translate along the first direction X, so that the transmission mechanism 300 sequentially transmits each battery cell 40 to the unloading device 30 of the battery production system.

[0073] The transfer device 10 provided in this application embodiment is provided with a base 100, which extends along the first direction X and is disposed on one side of a plurality of feeding devices 20 of a battery production system arranged at intervals along the first direction X, so that the base 100 and the plurality of feeding devices 20 are arranged in the same direction.

[0074] By setting up a drive mechanism 200 and at least two transmission mechanisms 300, the drive mechanism 200 is set on the base 100, and the at least two transmission mechanisms 300 are connected to the drive mechanism 200. The drive mechanism 200 drives the transmission mechanisms 300 to translate, so that each transmission mechanism 300 can be translated from the feeding device 20 to the unloading device 30 of the battery production system.

[0075] The driving mechanism 200 can drive the transmission mechanism 300 to translate along the first direction X, so that the extension direction of the base 100 and the arrangement direction of the feeding device 20 are the same as the translation direction of the transmission mechanism 300, which facilitates the transmission mechanism 300 to receive the battery cells 40 transmitted by each feeding device 20 along the second direction Y; and each transmission mechanism 300 can sequentially transmit the battery cells 40 it receives to the unloading device 30 to realize the transfer of battery cells 40; in addition, at least two transmission mechanisms 300 can improve the transfer efficiency of battery cells 40.

[0076] In summary, during the transfer of the battery cell 40, each transfer mechanism 300 always translates along the first direction X, and the transfer mechanism 300 is not prone to vibration, making it less likely for the battery cell 40 on each transfer mechanism 300 to be damaged.

[0077] The preferred technical solution of the transfer device 10 of this application embodiment is described below with reference to the accompanying drawings.

[0078] In some specific embodiments, the angle between the first direction X and the second direction Y is 45° to 135°. For example, the angle between the first direction X and the second direction Y is 45°, 90° or 135°.

[0079] In some embodiments, please refer to Figure 2 The drive mechanism 200 includes: a linear drive assembly 210, which is disposed on the base 100; a support member 220, which is connected to the linear drive assembly 210; and a transmission mechanism 300 disposed on the support member 220. The linear drive assembly 210 is used to drive the support member 220 to move, so as to drive the transmission mechanism 300 to translate along the first direction X.

[0080] In this embodiment, a linear drive assembly 210 and a support member 220 are provided. The linear drive assembly 210 is mounted on a base 100, which provides a support foundation for the linear drive assembly 210. The support member 220 is connected to the linear drive assembly 210, and the linear drive assembly 210 can drive the support member 220 to move linearly. A transmission mechanism 300 is mounted on the support member 220, and the support member 220 can drive the transmission mechanism 300 to translate along the first direction X, so that the transmission mechanism 300 can move from the feeding device 20 to the unloading device 30 without generating significant vibration.

[0081] In some specific embodiments, the linear drive assembly 210 includes: a first drive member 211, which is disposed on the base 100; a lead screw 212, which is rotatably connected to the base 100 along a first direction X, and the lead screw 212 is connected to the drive end of the first drive member 211; a support member 220 is rotatably connected to the lead screw 212; and a slide rod 213, which is connected to the base 100 along the first direction X, and the support member 220 is slidably connected to the slide rod 213; the first drive member 211 drives the lead screw 212 to rotate, so as to drive the support member 220 and the transmission mechanism 300 to translate along the first direction X.

[0082] By directly mounting the first drive component 211 on the base 100 and connecting the lead screw 212 to the drive end of the first drive component 211, the power transmission path can be shortened and the transmission efficiency improved; it can also reduce the accumulation of mechanical errors during the transmission process, thereby reducing the vibration of the battery cell 40 during the transfer process.

[0083] By setting a lead screw 212, which is connected to the driving end of the first driving member 211 to form a lead screw drive, the lead screw drive has self-locking properties and can maintain its position in a static state. Secondly, the lead screw drive can accurately convert rotary motion into linear motion, achieving high-precision position control. Furthermore, the linear motion converted by the lead screw drive can realize the translation of the support member 220. The transmission mechanism 300 is set on the support member 220, which can reduce vibration during the transfer of the battery cell 40. In addition, the lead screw drive has a large transmission ratio, which can achieve low-speed, high-torque output, facilitating the smooth start and stop of the transmission mechanism 300.

[0084] The slide rod 213 is connected to the base 100 along the first direction X, and the support member 220 is slidably connected to the slide rod 213. The slide rod 213 provides additional support and guidance for the support member 220. The slide rod 213 cooperates with the lead screw 212 to form a stable motion guiding system, which can reduce the jitter of the transmission mechanism 300, thereby improving the stability of the movement of the transmission mechanism 300 and thus preventing the battery cell 40 from being damaged due to jitter.

[0085] It should be noted that this embodiment does not limit the specific type of the first driving component 211. For example, the first driving component 211 is a servo motor or a stepper motor.

[0086] It should also be noted that this embodiment does not limit the connection method between the support member 220 and the transmission mechanism 300. For example, the transmission mechanism 300 is mounted on the support member 220 through the connector 400 described below.

[0087] In some other specific embodiments (not shown in this embodiment), the linear drive assembly 210 includes a telescopic drive member, the telescopic end of which is connected to the support member 220. The telescopic drive member extends and retracts to drive the support member 220 to move and drive the transmission mechanism 300 to translate along the first direction X.

[0088] This embodiment can easily drive the support member 220 to move by setting a telescopic drive component.

[0089] This embodiment does not limit the specific type of telescopic drive component. For example, the telescopic drive component is an electric telescopic rod or a hydraulic cylinder.

[0090] For some specific implementation methods, please refer to Figure 2 The number of support members 220 is at least two, and each support member 220 is arranged sequentially at intervals.

[0091] In this embodiment, when the transmission mechanism 300 has a large volume, at least two support members 220 provide better support for the transmission mechanism 300.

[0092] In some embodiments, please refer to Figure 2 and Figure 3 The transfer device 10 also includes a connector 400, which is connected to each support member 220, and the transmission mechanism 300 is connected to the connector 400.

[0093] In this embodiment, by setting a connector 400, which is connected to each support member 220, the driving mechanism 200 drives each support member 220 to move, which can drive the connector 400 to translate along the first direction X; by connecting each transmission mechanism 300 to the connector 400, the driving mechanism 200 can simultaneously drive at least two transmission mechanisms 300 to translate.

[0094] Furthermore, in some scenarios, the feeding device 20 and the unloading device 30 together form a many-to-one transmission mode. In this case, how to improve the transfer efficiency of the transfer device 10 is also a great challenge.

[0095] To address the above issues, please refer to some embodiments. Figure 1 The length of the base 100 along the first direction X (e.g. Figure 1 D1 in the figure is greater than the total length of each feeding device 20 along the first direction X (e.g., Figure 1 (D2 in the middle).

[0096] In this embodiment, by setting the length D1 of the base 100 along the first direction X to be greater than the total length D2 of each feeding device 20 along the first direction X, the base 100 has a certain amount of room for movement, which makes it easier for at least two transmission mechanisms 300 to carry and transmit the maximum number of battery cells 40, thereby improving the transfer efficiency of the battery cells 40.

[0097] To facilitate understanding of the above technical solutions, this embodiment will be illustrated using scenarios including but not limited to the following:

[0098] Please see Figure 1 The multiple feeding devices 20 include four feeding devices 21, 22, 23 and 24 arranged sequentially and spaced apart along the first direction X. Each feeding device 20 can transport two solar cells 40. The transfer device 10 includes three transfer mechanisms 300 arranged sequentially and spaced apart along the first direction X, namely a first transfer mechanism 301, a second transfer mechanism 302 and a third transfer mechanism 303. Each transfer mechanism 300 can transport two solar cells 40. The number of unloading devices 30 is one, and the unloading device 30 can transport two solar cells 40.

[0099] First, each of the first feeding device 21, the second feeding device 22, the third feeding device 23, and the fourth feeding device 24 carries two battery cells 40. The first transmission mechanism 301 is located on one side of the second feeding device 22 and can receive the two battery cells 40 on the second feeding device 22. The second transmission mechanism 302 is located on one side of the third feeding device 23 and can receive the two battery cells 40 on the third feeding device 23. The third transmission mechanism 303 is located on one side of the fourth feeding device 24 and can receive the two battery cells 40 on the fourth feeding device 24. The unloading device 30 is located on one side of the first transmission mechanism 301 and can directly receive the two battery cells 40 on the first transmission mechanism 301.

[0100] Secondly, the first transmission mechanism 301, the second transmission mechanism 302 and the third transmission mechanism 303 gradually move towards the first feeding device 21 along the first direction X. When the first transmission mechanism 301 moves to one side of the first feeding device 21, the first transmission mechanism 301 receives two battery cells 40 on the first feeding device 21. At this time, the second transmission mechanism 302 is located on one side of the unloading device 30, and the unloading device 30 can receive two battery cells 40 on the second transmission mechanism 302.

[0101] Next, the first transmission mechanism 301, the second transmission mechanism 302 and the third transmission mechanism 303 continue to move in the current direction. The first transmission mechanism 301 moves to the remaining position on the base 100, the second transmission mechanism 302 moves to one side of the first feeding device 21, and the third transmission mechanism 303 moves to one side of the unloading device 30. The unloading device 30 can receive the two battery cells 40 on the third transmission mechanism 303.

[0102] Then, the first transmission mechanism 301, the second transmission mechanism 302 and the third transmission mechanism 303 are translated along the direction of the first transmission mechanism 301 toward the third transmission mechanism 303. When the first transmission mechanism 301 is translated to one side of the unloading device 30, the unloading device 30 can receive the two battery cells 40 on the first transmission mechanism 301.

[0103] Finally, the first transmission mechanism 301, the second transmission mechanism 302 and the third transmission mechanism 303 are reset and continue to receive the battery cells 40 from the second feeding device 22, the third feeding device 23 and the fourth feeding device 24.

[0104] Therefore, by repeating the above process, the battery cells 40 on the four feeding devices 20 can be quickly transferred. Compared with setting up a single transfer mechanism 300 to transfer the battery cells 40 on the first feeding device 21, the second feeding device 22, the third feeding device 23 and the fourth feeding device 24 respectively, the transfer device 10 in this embodiment has a higher transfer efficiency for the battery cells 40.

[0105] It should be noted that the embodiments of this application do not limit the number of the feeding device 20, the transmission mechanism 300 and the unloading device 30. For example, the number of feeding devices can be four, the number of transmission mechanisms 300 can be three and the number of unloading devices 30 can be one.

[0106] It should also be noted that the embodiments of this application do not limit the number of battery cells 40 carried by the feeding device 20, the transmission mechanism 300 and the unloading device 30. For example, the feeding device 20, the transmission mechanism 300 and the unloading device 30 may each include two carrying units, and each carrying unit can carry and transmit one battery cell 40.

[0107] In other embodiments, please refer to Figure 3 and Figure 4 The transmission mechanism 300 includes: a support 310, which is connected to the drive mechanism 200; and a conveyor belt assembly 320, which is disposed on the support 310 and is used to transmit the battery cells 40.

[0108] In this embodiment, the conveyor belt assembly 320 is used as a component that directly contacts the battery cell 40, and its design has a decisive impact on the quality of the entire transmission process.

[0109] First, the conveyor belt assembly 320 enables continuous and smooth transmission of the battery cell 40, reducing the need for repeated gripping and releasing by traditional robotic arms, thereby greatly avoiding impact and vibration on the battery cell 40.

[0110] Secondly, the force applied by the conveyor belt assembly 320 to the battery cell 40 is evenly distributed. This uniform force distribution characteristic can greatly prevent the battery cell 40 from deforming or being damaged during transmission.

[0111] Finally, the continuous motion characteristics of the conveyor belt assembly 320 enable the cell 40 to be transported at high speed and with stability, thereby improving the efficiency of the entire production line.

[0112] It should be noted that this embodiment does not limit the specific structure of the bracket 310, as long as it can stably support the conveyor belt assembly 320. For example, the bracket 310 can be a T-shaped support rod, with the top of the T-shaped support rod connected to the bottom of both sides of the conveyor belt assembly 320, and the bottom of the T-shaped support rod connected to the drive mechanism 200.

[0113] In a specific implementation, when the transfer device 10 has a connector 400, the support 310 of the transmission mechanism 300 is connected to the connector 400.

[0114] In some other embodiments, please refer to Figure 4 and Figure 5 The conveyor belt assembly 320 includes: a vacuum conveyor belt 321, which has a vacuum chamber 322 inside and a plurality of adsorption holes 323 communicating with the vacuum chamber 322, the adsorption holes 323 being used to adsorb the battery cell 40; a second driving member 324, which is mounted on the bracket 310 and connected to the vacuum conveyor belt 321, and is used to drive the vacuum conveyor belt 321 to move; and a negative pressure member, which is connected to the vacuum chamber 322 and is used to generate negative pressure.

[0115] In this embodiment, a vacuum conveyor belt 321 and a negative pressure component are provided. The vacuum conveyor belt 321 has a vacuum cavity 322, and the negative pressure component is connected to the vacuum cavity 322. The negative pressure component can generate negative pressure in the vacuum cavity 322.

[0116] By setting multiple adsorption holes 323 on the vacuum conveyor belt 321 that communicate with the vacuum chamber 322, when a negative pressure is generated in the vacuum chamber 322, the adsorption holes 323 can adsorb the battery cells 40 on the vacuum conveyor belt 321, thereby improving the stability of the battery cells 40 during the transmission process.

[0117] By setting a second driving member 324, which is mounted on the bracket 310 and connected to the vacuum conveyor belt 321, the second driving member 324 can drive the vacuum conveyor belt 321 to move, thereby realizing the transmission of the battery cell 40.

[0118] It should be noted that this embodiment does not limit the specific type of the second driving component 324. For example, the second driving component 324 includes a servo motor or a stepper motor.

[0119] It should also be noted that this embodiment does not limit the number of vacuum conveyor belts 321 and negative pressure components. For example, there are two vacuum conveyor belts 321 and two negative pressure components, and each vacuum conveyor belt 321 is connected to each negative pressure component.

[0120] In some scenarios, while the drive mechanism 200 drives the transmission mechanism 300 to move, the conveyor belt assembly 320 also drives the battery cell 40 to move synchronously. This may cause the movement of the battery cell 40 to be affected by the drive mechanism 200, resulting in unstable movement of the battery cell 40.

[0121] For the above issues, please refer to Figure 4 and Figure 5 In some embodiments, the transmission mechanism 300 further includes: a sensor 325, which is mounted on the bracket 310 and is used to detect whether there is a battery cell 40 on the vacuum conveyor belt 321; and a controller (not shown), which is communicatively connected to the sensor 325, the negative pressure component, and the second drive component 324. When the sensor 325 detects that there is a battery cell 40 on the vacuum conveyor belt 321, the controller controls the negative pressure component to generate a negative pressure so that the vacuum conveyor belt 321 adsorbs the battery cell 40, and controls the second drive component 324 to stop running.

[0122] In this embodiment, a sensor 325 and a controller are configured. The controller is communicatively connected to the sensor 325, the negative pressure component, and the second drive component 324. When the sensor 325 detects a battery cell 40 on the transmission mechanism 300, the controller stops the second drive component 324 and generates a negative pressure to cause the vacuum conveyor belt 321 to adhere to the battery cell 40, thus fixing the battery cell 40 in a preset position. Simultaneously, the drive mechanism 200 controls the entire transmission mechanism 300 to translate, changing its position. During this translation, the position of the battery cell 40 remains constant, preventing adverse effects from the drive mechanism 200. Once the transmission mechanism 300 is in position, the controller restarts the second drive component 324 and stops the negative pressure component, allowing the vacuum conveyor belt 321 to transport the battery cell 40 normally.

[0123] It should be noted that the embodiments of this application do not limit the specific type of sensor 325. For example, sensor 325 can be an infrared sensor 325 or an ultrasonic sensor 325.

[0124] For some specific implementation methods, please refer to Figure 5 The negative pressure components include: a vacuum pipe 326, which is connected to a vacuum chamber 322; a vacuum pump 327, which is connected to the vacuum pipe 326 and is used to extract gas from the vacuum chamber 322 to generate negative pressure; a solenoid valve 328, which is connected to the vacuum pipe 326 and is used to control the opening or closing of the vacuum pipe 326; and a throttle valve 329, which is connected to the vacuum pipe 326 and is used to control the gas flow rate in the vacuum pipe 326.

[0125] By setting up a vacuum pump 327 and a vacuum pipe 326, the vacuum pipe 326 connects the vacuum pump 327 and the vacuum chamber 322. The vacuum pump 327 can continuously extract gas from the vacuum chamber 322 to maintain a stable negative pressure environment in the vacuum pipe 326 and the vacuum chamber 322, thereby ensuring that the vacuum conveyor belt 321 can effectively adsorb the battery cell 40.

[0126] By incorporating a solenoid valve 328 connected to a vacuum pipe 326, the solenoid valve 328 can open or close the vacuum pipe 326, achieving precise control of the negative pressure. This precise control capability allows the vacuum conveyor belt 321 to be activated or deactivated immediately when needed, thereby improving the flexibility and efficiency of the battery cell 40 transport process.

[0127] By setting a throttle valve 329, which is connected to the vacuum pipe 326, the gas flow rate in the vacuum pipe 326 can be precisely controlled by adjusting the opening of the throttle valve 329. This fine adjustment capability allows the vacuum conveyor belt 321 to provide the most suitable negative pressure intensity according to the needs of different battery cells 40, ensuring the adsorption effect while avoiding damage to the battery cells 40 due to excessive negative pressure.

[0128] It should be understood that the embodiments of this application are not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
