Description

Technical Field

[0001] This invention belongs to the field of battery assembly technology, and relates to an automatic battery cell assembly machine, particularly an automatic battery cell assembly machine based on visual inspection and recognition. Background Technology

[0002] Automated battery cell assembly, also known as automated cell stacking, refers to the process in which individual battery cells are precisely arranged and stacked according to design requirements during the lithium battery production process using automated equipment to form the basic structure of a battery module. Automated battery cell assembly machines based on visual inspection and recognition are automated devices that use industrial cameras and visual algorithms to replace human eyes in locating, detecting, and identifying battery cells, and guiding robotic arms and other actuators to complete precise grasping and stacking. They are key equipment for achieving large-scale, high-precision production of power batteries and consumer electronics batteries (such as mobile phone batteries).

[0003] A search revealed a Chinese patent document disclosing a battery cell stacking and bundling device [Announcement No.: CN121341493A]: "It includes a base, a transmission mechanism, and a transport mechanism. Both the transmission mechanism and the transport mechanism are located on the upper end of the base. The transmission mechanism receives the initial battery workpiece placed externally and smoothly transfers the workpiece to the top of the transport mechanism, providing initial positioning and transfer support for the subsequent transfer process of the workpiece. The transport mechanism undertakes the main transfer task of the workpiece, which can drive the workpiece to move along a preset path on the upper end of the base, conveying the workpiece from the feeding end of the equipment to the bundling operation area below the frame. The upper end of the base is equipped with a frame, which is the core support frame of the equipment. This battery cell stacking and bundling device features a limit frame to prevent displacement and ensure precise fitting, a guide plate to prevent tape issues, and a correction plate that works with a second electric telescopic component to correct the position of the workpiece and clamp it to prevent displacement. After correction, the return to its original position does not affect the frame's movement, thus improving the overall accuracy and stability of the operation."

[0004] By setting anti-slip components, fixing components, and buffer components in the transport mechanism to limit and fix the position of the battery cells, the stability of the transport of stacked battery cells is ensured. However, due to the mechanical transmission structure of the transport mechanism itself, the wear and vibration caused by the cumulative positioning error will still cause the stacked battery cells to deviate in position during transport, even after physical limiting of the stacked battery cells, resulting in a decrease in stacking accuracy. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an automatic battery cell assembly machine based on visual inspection and recognition. The technical problem this invention aims to solve is: how to ensure that stacked battery cells do not experience positional deviations during transportation and thus guarantee stacking accuracy.

[0006] The objective of this invention can be achieved through the following technical solutions: An automatic battery cell assembly machine based on visual inspection and recognition includes a housing. Inside the housing, a magnetic levitation conveying assembly and an environmental encapsulation system are provided for dust-free, moisture-free, and static-free stacking of battery cells and vibration-free conveying of the stacked battery cells. A positioning clamping assembly is provided above the magnetic levitation conveying assembly. A feeding frame is fixed at one end of the housing, and two vision gripping robots are fixed on the outer wall of the top of the housing. A vision transfer robot is fixed on the inner wall of the top of the housing. The magnetic levitation transport assembly includes a high-frequency power circuit box fixed to the inner wall of the bottom of the outer shell. A substrate is fixed to the top of the high-frequency power circuit box. Multiple electromagnetic coils are fixed in a grid pattern inside the substrate, and the multiple electromagnetic coils are electrically connected to the high-frequency power circuit box. The magnetic levitation conveying assembly further includes a carrier plate with a fixing groove at its bottom. A permanent magnet is fixed inside the fixing groove and magnetically levitates above the substrate. Four positioning pins are fixed at the four corners of the top of the carrier plate. The positioning clamp assembly includes a base plate with four positioning holes at its four corners. The positioning pins are slidably connected to the positioning holes. A positioning plate is fixed at the top of the base plate, and a first rubber pad is fixed on one side of the positioning plate. Two limiting plates are fixed on one side of the positioning plate, and limiting holes are opened inside the limiting plates. The positioning clamp assembly further includes a pressing plate with an inclined plate fixed at its top and a second rubber pad fixed on one side of the pressing plate. Two through grooves are opened at the bottom of the pressing plate and are slidably connected to the limiting plates. A sliding rod is fixed inside the through groove and is slidably connected to the limiting holes. Multiple return springs are fixed on the other side of the pressing plate, and a fixing plate is fixed at the other end of the multiple return springs. The fixing plate is fixed between the two limiting plates.

[0007] The working principle of this invention is as follows: Battery cells are conveyed to the loading frame via a conveyor belt or manual trolley. After inspection by a vision-based grasping robot, they are transferred to the stacking area. An environmental encapsulation system ensures that the temperature, humidity, dust, and static electricity on the surface of the battery cells meet the standards. Then, the vision-based transfer robot grasps and rotates the battery cells in the isolation chamber into the positioning fixture assembly to clamp and fix the stacked battery cells, thus limiting the position of the stacked battery cells. Then, a high-frequency power circuit box controls the power supply and de-powering of the grid-like electromagnetic coils inside the substrate. The electromagnetic effect generated by the grid-like electromagnetic coils moves forward in a wave-like manner. With the cooperation of permanent magnets, the carrier plate and the base plate are pushed, causing the stacked battery cells to float and move forward above the substrate. This replaces the traditional linear transmission mechanism. Through the interaction between the substrate composed of electromagnetic coil array and the permanent magnets of the carrier plate, non-contact and frictionless precision movement of the stacked battery cells on a two-dimensional plane is achieved. Precise conveying and hovering positioning fundamentally eliminate the accuracy loss caused by vibration and wear. This ensures that the automatic battery cell assembly machine based on visual inspection and recognition will not experience positional deviations in the stacked battery cells during transport due to wear and cumulative positioning errors caused by the mechanical transmission structure of the transport mechanism itself. This guarantees the accuracy of the stacked battery cells during transport, facilitating subsequent welding. When disassembling the base plate, the base plate can be separated from the carrier plate by moving it upward along the positioning pins and positioning holes, which facilitates the replacement and maintenance of the clamping components and reduces their limitations. The position of the extrusion plate and battery cells is limited by the limiting plate to prevent them from shifting. At the same time, the vertical position of the extrusion plate is limited by the sliding rod and the limiting hole to prevent the extrusion plate from shifting upward during movement and causing unstable clamping. The inclined plate facilitates the stacking of battery cells in the clamping state of the extrusion plate and prevents the extrusion plate from obstructing the stacking position of the battery cells.

[0008] The environmental encapsulation system includes a constant temperature and humidity unit, an FFU fan filter unit, and an ion fan, all of which are fixed to the top of the outer casing.

[0009] Using the above structure, the battery cells are treated by a constant temperature and humidity unit, an FFU fan filter unit, and an ion fan, ensuring that the temperature, humidity, dust, and static electricity on the surface of the battery cells meet the standards. At the same time, the inside of the casing is a closed area to eliminate environmental variables and transform environmental variables into stable process parameters.

[0010] The environmental encapsulation system also includes a temperature and humidity sensor electrically connected to the constant temperature and humidity unit, a particulate matter sensor electrically connected to the FFU fan filter unit, and an electrostatic potentiometer electrically connected to the ion fan.

[0011] Using the above structure, the battery cell is tested by temperature and humidity sensors, particulate matter sensors, and electrostatic potentiometers to measure the temperature, humidity, dust, and static electricity on the surface of the battery cell.

[0012] An industrial dehumidifier is fixed to the top of the outer casing.

[0013] With the above structure, when the dehumidification capacity of the constant temperature and humidity unit is insufficient, the industrial dehumidifier can be started to increase the dehumidification capacity and further improve the dehumidification effect.

[0014] An industrial computer is fixedly mounted on one side of the outer casing. The high-frequency power circuit box, constant temperature and humidity unit, FFU fan filter unit, ion fan and industrial dehumidifier are all electrically connected to the industrial computer.

[0015] Using the above structure, an industrial computer processes and controls the data of the high-frequency power circuit box, constant temperature and humidity unit, FFU fan filter unit, ion fan and industrial dehumidifier.

[0016] An observation window is provided in the middle of one side of the outer casing, and a transparent glass is fixed inside the observation window. An inner automatic door and an outer automatic door are fixed inside both ends of the outer casing.

[0017] The above structure allows for observation of the interior of the casing through the combination of an observation window and transparent glass, preventing accidents. The inner and outer automatic doors work together to form an isolation chamber, which isolates the external environment from the battery cells, preventing external battery cells from contaminating the internal environment of the casing.

[0018] Compared with existing technologies, this automatic battery cell assembly machine based on visual inspection and recognition has the following advantages: 1. This invention controls the power supply and de-energization of a grid-like array of electromagnetic coils inside a substrate via a high-frequency power circuit box. This causes the electromagnetic effect generated by the grid-like electromagnetic coils to move forward in a wave-like manner. With the cooperation of permanent magnets, this propels the carrier plate and base plate, causing the stacked battery cells to float and move forward above the substrate. This replaces the traditional linear transmission mechanism. Through the interaction between the substrate, composed of an electromagnetic coil array, and the permanent magnets on the carrier plate, non-contact, frictionless, and precise transport and hovering positioning of the stacked battery cells on a two-dimensional plane is achieved. This fundamentally eliminates the accuracy loss caused by vibration and wear. As a result, this automatic battery cell assembly machine based on visual inspection and recognition will not experience positional deviations in the stacked battery cells during transport due to wear and accumulated positioning errors caused by the mechanical transmission structure of the transport mechanism itself. This ensures that the stacked battery cells maintain accuracy during transport, facilitating subsequent welding, etc.

[0019] 2. This invention uses temperature and humidity sensors, particulate matter sensors, and electrostatic potentiometers to detect the battery cells, testing the surface temperature, humidity, dust, and static electricity of the battery cells. This information is transmitted to an industrial computer, which processes it and then transmits it to a constant temperature and humidity unit, an FFU (Fan Filter Unit), and an ion fan. The battery cells are then treated by these components to ensure that the surface temperature, humidity, dust, and static electricity meet the required standards. A vision-based transfer robot then picks up the battery cells from the isolation chamber, rotates them to the top of the base plate, and places them in contact with the positioning plate. This ensures consistency in environment and process. The use of vision and robotics technologies enables intelligent operation, significantly improving the production quality, efficiency, and flexible production capabilities of the battery modules.

Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figures 1-7 As shown, this automatic battery cell assembly machine based on visual inspection and recognition includes a housing 101. Inside the housing 101, there is a magnetic levitation conveying component and an environmental encapsulation system, which are used to stack battery cells without dust, moisture and static electricity and to convey the stacked battery cells without vibration. A positioning clamping component is set above the magnetic levitation conveying component. A feeding frame 109 is fixed at one end of the housing 101, and two vision gripping robots 108 are fixed on the outer wall of the top of the housing 101. A vision transfer robot is fixed on the inner wall of the top of the housing 101. The magnetic levitation transport assembly includes a high-frequency power circuit box 201 fixed to the inner wall of the bottom end of the outer shell 101. A substrate 202 is fixed at the top of the high-frequency power circuit box 201. Multiple electromagnetic coils are fixed in a grid pattern inside the substrate 202, and the multiple electromagnetic coils are electrically connected to the high-frequency power circuit box 201. The magnetic levitation conveying assembly also includes a carrier plate 301. A fixing groove 302 is formed at the bottom of the carrier plate 301, and a permanent magnet 303 is fixed inside the fixing groove 302. The permanent magnet 303 is magnetically levitated above the base plate 202. Four positioning pins 304 are fixed at the four corners of the top of the carrier plate 301. The positioning clamp assembly includes a base plate 401. Four positioning holes 406 are formed at the four corners inside the base plate 401. The positioning pins 304 are slidably connected to the positioning holes 406. A positioning plate 402 is fixed at the top of the base plate 401, and a first rubber pad 403 is fixed on one side of the positioning plate 402. Two limiting plates 404 are fixed on one side of the positioning plate 402. The positioning plate 404 has a limiting hole 409 inside. The positioning fixture assembly also includes a pressing plate 410. The top of the pressing plate 410 is fixed with an inclined plate 430, and a second rubber pad 420 is fixed on one side of the pressing plate 410. The bottom of the pressing plate 410 has two through grooves 408, which are slidably connected to the limiting plate 404. A sliding rod 407 is fixed inside the through groove 408, which is slidably connected to the limiting hole 409. Multiple return springs 440 are fixed on the other side of the pressing plate 410, and a fixing plate 405 is fixed at the other end of the multiple return springs 440. The fixing plate 405 is fixed between the two limiting plates 404.

[0030] Battery cells are conveyed to the loading frame 109 via conveyor belt or manual trolley. After inspection by a vision-grabbing robot 108, they are transferred to the stacking area. An environmental encapsulation system ensures that the temperature, humidity, dust, and static electricity on the surface of the battery cells meet the standards. Then, a vision transfer robot picks up the battery cells from the isolation chamber and rotates them into the positioning fixture assembly to clamp and fix the stacked battery cells, thus limiting the position of the stacked battery cells. The high-frequency power circuit box 201 controls the power supply and de-powering of the grid-like electromagnetic coils inside the substrate 202. The electromagnetic effect generated by the grid-like electromagnetic coils moves forward in a wave-like manner. With the cooperation of the permanent magnet 303, it pushes the carrier plate 301 and the base plate 401, causing the stacked battery cells to float and move forward above the substrate 202. This replaces the traditional linear transmission mechanism. Through the interaction between the substrate 202, which is composed of an electromagnetic coil array, and the permanent magnet 303 of the carrier plate 301, the stacked battery cells are transported and suspended in a two-dimensional plane without contact or friction, achieving precise transport and suspension. The positioning fundamentally eliminates the accuracy loss caused by vibration and wear, thus ensuring that the automatic battery cell assembly machine based on visual inspection and recognition will not experience positional deviations in the stacked battery cells during transportation due to wear and positioning cumulative errors caused by the mechanical transmission structure characteristics of the transportation mechanism itself. This ensures that the stacked battery cells maintain accuracy during transportation. When disassembling the base plate 401, the base plate 401 can be separated from the carrier plate 301 by moving the base plate 401 upward along the positioning pin 304 and positioning hole 406, which facilitates the replacement and maintenance of the clamping components and reduces their limitations. The position of the extrusion plate 410 and the battery cells is limited by the limiting plate 404 to prevent them from shifting. At the same time, the upper and lower positions of the extrusion plate 410 are limited by the sliding rod 407 and the limiting hole 409 to prevent the extrusion plate 410 from shifting upward during movement and causing unstable clamping. The inclined plate 430 facilitates the stacking of battery cells in the clamping state of the extrusion plate 410 and prevents the extrusion plate 410 from obstructing the stacking position of the battery cells.

[0031] The environmental encapsulation system includes a constant temperature and humidity unit 103, an FFU fan filter unit 104, and an ion fan 106. The constant temperature and humidity unit 103, the FFU fan filter unit 104, and the ion fan 106 are all fixed to the top of the outer casing 101.

[0032] In this embodiment, the battery cell is processed by a constant temperature and humidity unit 103, an FFU fan filter unit 104, and an ion fan 106 to ensure that the temperature, humidity, dust, and static electricity on the surface of the battery cell meet the standards. At the same time, the inside of the casing is a closed area to eliminate environmental variables and transform environmental variables into stable process parameters.

[0033] The environmental encapsulation system also includes a temperature and humidity sensor electrically connected to the constant temperature and humidity unit 103, a particulate matter sensor electrically connected to the FFU fan filter unit 104, and an electrostatic potentiometer electrically connected to the ion fan 106.

[0034] In this embodiment, the battery cell is detected by a temperature and humidity sensor, a particulate matter sensor, and an electrostatic potentiometer to test the temperature, humidity, dust, and static electricity on the surface of the battery cell.

[0035] An industrial dehumidifier 105 is fixed to the top of the outer casing 101.

[0036] In this embodiment, when the dehumidification capacity of the constant temperature and humidity unit 103 is insufficient, the industrial dehumidifier 105 can be started to increase the dehumidification capacity and further improve the dehumidification effect.

[0037] An industrial computer 102 is fixedly mounted on one side of the outer casing 101. The high-frequency power circuit box 201, the constant temperature and humidity unit 103, the FFU fan filter unit 104, the ion fan 106, and the industrial dehumidifier 105 are all electrically connected to the industrial computer 102.

[0038] In this embodiment, the industrial computer 102 performs data processing and control on the high-frequency power circuit box 201, the constant temperature and humidity unit 103, the FFU fan filter unit 104, the ion fan 106, and the industrial dehumidifier 105.

[0039] An observation window is provided in the middle of one side of the outer casing 101, and a transparent glass 107 is fixed inside the observation window. An inner automatic door 110 and an outer automatic door 120 are fixed inside both ends of the outer casing 101.

[0040] In this embodiment, the observation window and transparent glass 107 are used together to observe the internal condition of the outer casing 101 to prevent accidents. The inner automatic door 110 and the outer automatic door 120 are used together to form an isolation cavity between them. The isolation cavity isolates the external environment and the battery cell, preventing the battery cell from entering from the outside from contaminating the internal environment of the outer casing 101.

[0041] Working principle of the invention: The battery cells are conveyed to the loading frame 109 via a conveyor belt or manual trolley. After inspection by a vision-based gripping robot 108, they are transferred to the isolation chamber between the inner automatic door 110 and the outer automatic door 120. Temperature and humidity sensors, particulate matter sensors, and electrostatic potentiometers then monitor the battery cells, testing their surface temperature, humidity, dust, and static electricity. This information is transmitted to an industrial computer 102, which processes the data and then transmits it to the constant temperature and humidity unit 103, the FFU fan filter unit 104, and the ion fan 106. Finally, the battery cells are processed by a constant temperature and humidity control unit 103, an FFU fan filter unit 104, and an ion fan 106. The temperature and humidity control unit 103, FFU fan filter unit 104, and ion fan 106 process the battery cells to ensure that the temperature, humidity, dust, and static electricity on the surface of the battery cells meet the standards. Then, a vision transfer robot picks up the battery cells from the isolation chamber and rotates them above the base plate 401, placing them against the positioning plate 402. After a certain number of battery cells are stacked, the pressure from the battery cells pushes the compression plate 410 backward, which in turn compresses the return spring 440. The return spring 440, under its elastic force, provides a reaction force to push the compression plate 410 forward, clamping and fixing the stacked battery cells. After the battery cells are stacked, they are positioned. Then, the high-frequency power circuit box 201 controls the power supply and de-powering of the grid-like electromagnetic coils inside the substrate 202. This causes the electromagnetic effect generated by the grid-like electromagnetic coils to move forward in a wave-like manner. With the cooperation of the permanent magnet 303, the carrier plate 301 and the base plate 401 are pushed and driven to make the stacked battery cells float and move forward above the substrate 202. Then, a vision transfer robot transfers the stacked battery cells to another isolation cavity. Another vision grasping robot 108 grasps the base plate 401, causing the base plate 401 to move along the positioning pins. 304 and positioning hole 406 move upward, thereby detaching from carrier plate 301, so that the fixed clamping component connected to base plate 401 and the stacked battery cells can move to the next process. After the stacked battery cells are welded, the stacked battery cells are taken out. Finally, another vision grasping robot 108 resets base plate 401, thus completing the entire workflow. The vision grasping robot is a multi-axis robotic arm that grasps objects by vision. It can grasp objects of different positions, sizes and shapes. It is common on the market and can be purchased and used directly, so it will not be described in detail.

[0042] In summary, by interacting with the permanent magnet 303 of the carrier plate 301 and the substrate 202 composed of an electromagnetic coil array, the stacked battery cells are accurately transported and hovered on a two-dimensional plane without contact or friction. This fundamentally eliminates the accuracy loss caused by vibration and wear. As a result, the automatic battery cell assembly machine based on visual inspection and recognition will not experience positional deviations in the stacked battery cells during transport due to wear and positioning errors caused by the mechanical transmission structure characteristics of the transport mechanism itself. This ensures that the stacked battery cells maintain accuracy during transport, which is convenient for subsequent welding and other processes.
