During the preparation of the electrode assembly, a detection device is usually used to detect the quality of the electrode assembly. Therefore, how to improve the accuracy and stability of the detection device is an urgent problem to be solved in battery technology. Utility Model Content

[0004] In view of the above problems, the present application provides a detection device and a battery production equipment, which can improve the detection accuracy and reliability of the detection device.

[0005] In the first aspect, the embodiment of the present application provides a detection device, which includes a carrier, a gripping component, a measuring component and a detection component, wherein the carrier is used to carry the electrode assembly, and the gripping component is used to grip the electrode assembly and transfer it to the carrier. The measuring component is spaced apart from the carrier, and the measuring component is used to measure the position of the gripping component. The detection component is spaced apart from the carrier, and the detection component is used to detect the deflection of the electrode assembly in a preset direction.

[0006] The above technical solution improves the placement accuracy of the electrode assembly by setting a measuring component to measure the position of the grasping component, which can provide a good basis for the subsequent detection component to detect the deflection amount of the electrode assembly, thereby improving the detection accuracy and reliability of the entire detection device.

[0007] In some embodiments of the first aspect, the measuring assembly includes a first measuring component and a second measuring component, the first measuring component is arranged relative to the carrier along a first direction and is used to measure the distance between the grabbing component and the first measuring component in the first direction. The second measuring component is arranged relative to the carrier along a second direction and is used to measure the distance between the grabbing component and the second measuring component in the second direction, and the first direction and the second direction intersect.

[0008] The above technical solution can further improve the positioning accuracy of the measuring component for the grasping component by setting the first measuring component and the second measuring component to measure the distance of the grasping component in different directions. In addition, the first measuring component and the second measuring component are set separately, which is conducive to enhancing the adaptability of the measuring component to different working environments and conditions, and can improve the versatility and flexibility of the entire detection device.

[0009] In some embodiments of the first aspect, the first measuring component includes a distance sensor, and / or the second measuring component includes a distance sensor.

[0010] The distance sensor of the above technical solution has low dependence on environmental factors such as light, background, temperature or humidity, which is conducive to improving the stability and reliability of the first measuring component. In addition, the distance sensor can provide direct numerical output, which is conducive to reducing the complexity of data processing, reducing computing costs and processing time, and improving the measurement efficiency of the first measuring component.

[0011] In some embodiments of the first aspect, the detection device further includes a first control component, which is communicatively connected to the gripping component and the measuring component, and the first control component is configured to control the movement of the gripping component according to measurement information obtained by the measuring component.

[0013] In some embodiments of the first aspect, the grasping component includes two first clamping members, which are arranged opposite to each other along a first direction and can move relative to each other along the first direction.

[0014] The two first clamping members of the above technical solution can grasp and release the electrode assembly through simple structural design and motion logic, so as to reduce the structural complexity of the entire detection device, which can not only reduce the failure rate of the entire detection device, but also reduce the maintenance cost of the entire detection device.

[0016] The above technical solution opens air blowing ports on both sides of the first clamping member. Before the detection assembly detects the electrode assembly, the air blowing ports can blow out airflow, which can blow away the diaphragm hanging on the circumferential edge of the electrode assembly, reducing the influence of the diaphragm on the detection assembly, and can also blow away impurities on the surface of the electrode assembly, reducing the influence of impurities on the detection assembly. Therefore, the detection accuracy and reliability of the entire detection device can be further improved.

The first section is connected between the two second sections and the converging section, the two second sections are at a preset angle and respectively connect the first sub-port and the second sub-port to the first section.

[0020] The above technical solution can not only improve the blowing efficiency and effect by providing two second sections with a preset angle, but also reduce the risk of airflow damaging the diaphragm and improve the utilization efficiency of the gas.

[0021] In some embodiments of the first aspect, the preset angle is an acute angle.

[0022] The acute angle design between the two second sections can make the gas output from the first sub-port and the second sub-port more concentrated, so that the gas can more effectively reach and blow up the diaphragm farther away, further increasing the reach of the gas, thereby improving the overall effect of blowing up the diaphragm.

[0026] The above technical solution can further improve the detection accuracy of the detection component for the electrode assembly by setting the first detection component and the second detection component to perform deflection detection on the electrode assembly in different directions respectively.

[0063] With the development of new energy technology, batteries are used more and more widely, for example, in mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes and electric tools, etc.

[0064] In a battery cell, the quality of the electrode assembly is an important factor affecting the battery performance. During the preparation of the electrode assembly, a detection device is usually used to detect the quality of the electrode assembly. However, during the detection of the electrode assembly by the current detection device, after the electrode assembly is shipped by the clamp and conveyed by the conveyor belt, the position deviation of the electrode assembly at the detection station is large, resulting in inaccurate detection results of the electrode assembly by the detection component.

[0065] Based on the above considerations, the present application designs a detection device, which includes a carrying platform, a grabbing component, a measuring component and a detection component. The carrying platform is used to carry the electrode assembly, and the grabbing component is used to grab the electrode assembly and transfer it to the carrying platform. The measuring component is spaced apart from the carrying platform, and the measuring component is used to measure the position of the grabbing component. The detection component is spaced apart from the carrying platform, and the detection component is used to detect the deflection of the electrode assembly in a preset direction.

[0066] During the process of the detection device detecting the electrode assembly, when the grasping component grasps the electrode assembly and transfers it to the supporting platform, the measuring component can measure the position of the grasping component to accurately position the grasping component, so that the grasping component can accurately place the electrode assembly at the preset position of the supporting platform, thereby improving the placement accuracy of the electrode assembly. After the grasping component places the electrode assembly on the supporting platform, the detection component detects the electrode assembly again to determine whether the deflection of the electrode assembly meets the requirements. In this way, the above technical solution can provide a good basis for the subsequent detection component to detect the deflection of the electrode assembly by setting the measuring component to measure the position of the grasping component to improve the placement accuracy of the electrode assembly, thereby improving the detection accuracy and reliability of the entire detection device.

[0067] The following first introduces the detection device provided in the embodiments of the present application with reference to the accompanying drawings.

Figure 2 A schematic diagram of the structure of a detection device provided in some embodiments of the present application in which a grasping component loads an electrode assembly onto a supporting platform. Figure 3 A schematic structural diagram of an electrode assembly deflected in a first direction detected by a detection device provided in some embodiments of the present application. Figure 4 A schematic structural diagram of an electrode assembly deflected in a second direction detected by a detection device provided in some embodiments of the present application.

[0068] like Figures 1 to 4As shown, an embodiment of the present application provides a detection device, which includes a carrier 10, a gripping component 20, a measuring component 30 and a detection component 40. The carrier 10 is used to carry the electrode assembly 100, and the gripping component 20 is used to grip and transfer the electrode assembly 100 to the carrier 10. The measuring component 30 is spaced apart from the carrier 10, and the measuring component 30 is used to measure the position of the gripping component 20. The detection component 40 is spaced apart from the carrier 10, and the detection component 40 is used to detect the deflection of the electrode assembly 100 in a preset direction.

[0069] Exemplarily, the main function of the carrier 10 is to stably carry the electrode assembly 100. In the embodiment of the present application, the electrode assembly 100 is a laminated structure as an example for explanation, and the electrode assembly 100 includes a plurality of stacked pole pieces 110. In terms of design, the carrier 10 should have sufficient strength and stability to accommodate electrode assemblies 100 of different sizes and weights. A buffer layer may be provided on the surface of the carrier 10 to reduce scratches or damage to the electrode assembly 100 during the inspection process. The buffer layer may be made of, but is not limited to, polyethylene, polypropylene, polystyrene, polyurethane, bubble film, or corrugated cardboard.

[0070] The function of the gripping component 20 is to accurately grip the electrode assembly 100 and stably transfer it to the carrier 10. As an example, the gripping component 20 includes a mechanical arm and a mechanical gripper, and the structural design of the mechanical gripper matches the material properties and surface properties of the electrode assembly 100, so that the mechanical gripper can firmly grip the electrode assembly 100 during the gripping process without causing damage to the electrode assembly 100. Among them, a visual recognition device can be provided on the gripping component 20, so that the gripping component 20 can accurately identify the electrode assembly 100 and its position.

[0071] The main function of the measuring component 30 is to measure the position of the grasping component 20 to accurately position the grasping component 20, so that the grasping component 20 can accurately place the electrode assembly 100 at the preset position of the carrier 10. The measuring component 30 can provide real-time data to help the grasping component 20 adjust the path and position to improve the placement accuracy of the electrode assembly 100. Among them, the measuring component 30 can locate the position of the grasping component 20 by distance measurement, or by optical imaging. As an example, the measuring component 30 includes high-precision measuring devices and positioning systems, such as optical sensors, optical cameras or laser rangefinders, to provide real-time position feedback.

[0072] The function of the detection component 40 is to detect the deflection of the electrode assembly 100 in a preset direction. As an example, the electrode assembly 100 mentioned in the embodiment of the present application is a laminated electrode assembly, and the laminated electrode assembly includes a plurality of stacked pole pieces 110. Among them, the deflection of the electrode assembly 100 in the preset direction can be the deflection n of the plurality of stacked pole pieces 110 along the first direction X, or the deflection m of the plurality of stacked pole pieces 110 along the second direction Y. Among them, the first direction X can be understood as the width direction of the electrode assembly 100, and the second direction Y can be understood as the length direction of the electrode assembly 100. As an example, the detection component 40 can include, but is not limited to, an optical sensor, an optical camera or a laser scanner. The detection component 40 can be connected to a data processing system, which is used to analyze the data detected by the detection component 40 and give an accurate deflection amount.

[0073] During the process of the detection device detecting the electrode assembly 100, when the gripping component 20 grips the electrode assembly 100 and transfers it to the carrier 10, the measuring component 30 can measure the position of the gripping component 20 to accurately position the gripping component 20, so that the gripping component 20 can accurately place the electrode assembly 100 at the preset position of the carrier 10, thereby improving the placement accuracy of the electrode assembly 100. After the gripping component 20 places the electrode assembly 100 on the carrier 10, the detection component 40 detects the electrode assembly 100 again to determine whether the deflection amount of the electrode assembly 100 meets the requirements.

[0074] In this way, the above technical solution improves the placement accuracy of the electrode assembly 100 by setting the measuring component 30 to measure the position of the grasping component 20, which can provide a good basis for the subsequent detection component 40 to detect the deflection amount of the electrode assembly 100, thereby improving the detection accuracy and reliability of the entire detection device.

[0075] In some embodiments, the measuring assembly 30 includes a first measuring component 31 and a second measuring component 32, wherein the first measuring component 31 is disposed opposite to the carrier 10 along a first direction X and is used to measure the distance between the grasping component 20 and the first measuring component 31 in the first direction X. The second measuring component 32 is disposed opposite to the carrier 10 along a second direction Y and is used to measure the distance between the grasping component 20 and the second measuring component 32 in the second direction Y, and the first direction X and the second direction Y intersect.

[0076] Exemplarily, when the gripping member 20 moves to the position of the carrying platform 10, the first measuring member 31 measures the gripping member 20 and obtains the first distance between the first measuring member 31 and the gripping member 20 in the first direction X. If the first distance meets the first preset value, the position of the gripping member 20 in the first direction X meets the requirement; if the first distance does not meet the first preset value, the gripping member 20 is adjusted along the first direction X according to the difference between the first distance and the first preset value, so that the first distance meets the first preset value. As an example, the first preset value can be the distance between the first measuring member 31 and the side edge of the carrying platform 10 close to the first measuring member 31. When the first distance is greater than the first preset value, the gripping member 20 is moved along the first direction X close to the first measuring member 31 until the first distance is equal to the first preset value; when the first distance is less than the first preset value, the gripping member 20 is moved away from the first measuring member 31 along the first direction X until the first distance is equal to the first preset value.

[0077] The second measuring component 32 measures the grasping component 20 and obtains the second distance between the second measuring component 32 and the grasping component 20 in the second direction Y. If the second distance meets the second preset value, the position of the grasping component 20 in the second direction Y meets the requirement; if the second distance does not meet the second preset value, the grasping component 20 is adjusted along the second direction Y according to the difference between the second distance and the second preset value, so that the second distance meets the second preset value. As an example, the second preset value can be the distance between the second measuring component 32 and the side edge of the supporting platform 10 close to the second measuring component 32. When the second distance is greater than the second preset value, the grasping component 20 is moved along the second direction Y close to the second measuring component 32 until the second distance is equal to the second preset value; when the second distance is less than the second preset value, the grasping component 20 is moved away from the second measuring component 32 along the second direction Y until the second distance is equal to the second preset value.

[0078] The above technical solution can further improve the positioning accuracy of the grabbing component 20 by the measuring component 30 by setting the first measuring component 31 and the second measuring component 32 to measure the distance in different directions of the grabbing component 20. In addition, the first measuring component 31 and the second measuring component 32 are set separately, which is conducive to enhancing the adaptability of the measuring component 30 to different working environments and conditions, and can improve the versatility and flexibility of the entire detection device.

[0079] In some embodiments, the first measuring component 31 comprises a distance sensor.

[0080] Exemplarily, the distance sensor may be, but is not limited to, a laser rangefinder, an infrared distance sensor, a photoelectric distance sensor, or an ultrasonic distance sensor.

[0081] The distance sensor of the above technical solution has low dependence on environmental factors such as light, background, temperature or humidity, which is conducive to improving the stability and reliability of the first measuring component 31. In addition, the distance sensor can provide direct numerical output, which is conducive to reducing the complexity of data processing, reducing calculation costs and processing time, and improving the measurement efficiency of the first measuring component 31.

[0082] In some optional embodiments, the second measuring component 32 includes a distance sensor.

[0083] In some embodiments, the detection device further includes a first control component 50 , which is communicatively connected to the gripping component 20 and the measuring component 30 , and is configured to control the movement of the gripping component 20 according to the measurement information obtained by the measuring component 30 .

[0084] Exemplarily, the communication connection between the first control component 50 and the gripping component 20 may be a wired communication connection or a wireless communication connection. The communication connection between the first control component 50 and the measuring component 30 may be a wired communication connection or a wireless communication connection. The first control component 50 may be, but is not limited to, a central control computer, a programmable logic controller, or an industrial computer.

[0085] During the process of the detection device detecting the electrode assembly 100, when the grasping component 20 grasps the electrode assembly 100 and transfers it to the supporting platform 10, the measuring component 30 can measure the position of the grasping component 20 and generate measurement information, and send the measurement information to the first control component 50. The first control component 50 can generate control information based on the measurement information and send the control information to the grasping component 20. The grasping component 20 then moves to adjust its position based on the control information, so that the grasping component 20 can accurately place the electrode assembly 100 at the preset position of the supporting platform 10.

[0086] The above technical solution realizes the automation of the position adjustment of the grabbing component 20 by setting the first control component 50, which can not only improve the operational accuracy of the position adjustment of the grabbing component 20, but also improve the efficiency of the position adjustment of the grabbing component 20, thereby further improving the overall working efficiency and reliability of the detection device.

[0087] In some embodiments, the grabbing component 20 includes two first clamping members 21 , which are arranged opposite to each other along the first direction X and can move relative to each other along the first direction X.

[0088] Exemplarily, the two first clamping members 21 cooperate with each other to clamp or release the electrode assembly 100, and the two first clamping members 21 clamp the two sides of the electrode assembly 100 in the first direction X. Among them, one of the two first clamping members 21 may be fixedly arranged, and the other may be movably arranged along the first direction X, or both of the first clamping members 21 may be movably arranged along the first direction X.

[0089] As an example, in the case where both of the two first clamping members 21 are movable along the first direction X, the two first clamping members 21 can be arranged to move independently of each other or to move in coordination. The arrangement of independent movement means that the movement state of one of the two first clamping members 21 will not affect the movement state of the other, for example, when one of the two first clamping members 21 moves close to the electrode assembly 100, the other can move close to the electrode assembly 100 or move away from the electrode assembly 100; the arrangement of coordinated movement means that the movement state of one of the two first clamping members 21 will drive the other to move in the same movement state, for example, when one of the two first clamping members 21 moves close to the electrode assembly 100, it will drive the other to move close to the electrode assembly 100 as well.

[0090] When the grasping component 20 grasps the electrode assembly 100 and transfers it to the carrier 10, the grasping component 20 first moves to the position of the electrode assembly 100, and the two first clamping members 21 move away from each other along the first direction X, and then the grasping component 20 moves closer to the electrode assembly 100, so that the two first clamping members 21 are respectively located on both sides of the electrode assembly 100 along the first direction X, and then the two first clamping members 21 move closer to each other along the first direction X to clamp the electrode assembly 100. Then, the grasping component 20 clamps the electrode assembly 100 and transfers it to the preset position of the carrier 10.

[0091] Optionally, the gripping member 20 may include a driving member connected to the first clamping member 21 to drive the first clamping member 21 to move. The driving member may be, but is not limited to, a motor, a pneumatic drive, or a hydraulic drive.

[0092] Optionally, the first clamping member 21 may be a plate-shaped structure, a block-shaped structure or a columnar structure, etc. The surface of the first clamping member 21 for contacting the electrode assembly 100 may be provided with a buffer layer to reduce the risk of the first clamping member 21 scratching the electrode assembly 100. The buffer layer may be made of, but not limited to, polyethylene, polypropylene, polystyrene, polyurethane, bubble film or corrugated cardboard.

[0093] The two first clamping members 21 of the above technical solution can grasp and release the electrode assembly 100 through simple structural design and motion logic, so as to reduce the structural complexity of the entire detection device, which can not only reduce the failure rate of the entire detection device, but also reduce the maintenance cost of the entire detection device.

[0094] Figure 5 This is a schematic diagram of the structure of the grabbing component and the electrode assembly of the detection device provided in some embodiments of the present application. Figure 6 for Figure 5 Schematic diagram of the cross-sectional structure along AA.

[0095] Continue to refer Figures 5 and 6 In some embodiments, the first clamping member 21 is provided with blowing ports 22 on both sides of the second direction Y, and a flow channel 23 is provided inside the first clamping member 21, and the flow channel 23 is used to connect the blowing port 22 and the air source, and the first direction X and the second direction Y intersect.

[0096] Exemplarily, the gas source is used to output gas, and the function of the flow channel 23 is to connect the air outlet 22 with the external gas source, and the gas passes through the flow channel 23 and is blown out through the air outlet 22. Optionally, the gas source can be an air compressor or a hair dryer.

[0097] It should be noted that the electrode assembly 100 includes pole pieces 110 and diaphragms 120 stacked along a third direction Z. Since the diaphragm 120 needs to cover the anode to reduce the risk of overlap between the anode pole piece and the cathode pole piece, the diaphragms 120 located at both ends of the electrode assembly 100 in the third direction Z will produce a certain amount of redundancy. The redundant diaphragms 120 will hang over the circumferential edge of the electrode assembly 100, which will block the edge portion of the electrode assembly 100, thereby affecting the detection effect of the detection component 40 on the deflection of the electrode assembly 100.

[0098] In this way, during the process of the detection device detecting the electrode assembly 100, after the grasping component 20 places the electrode assembly 100 at the preset position of the supporting platform 10, the blowing ports 22 located on both sides of the first clamping member 21 can blow air to the outside to blow away the diaphragm 120 hanging on the circumferential edge of the electrode assembly 100, so that the diaphragm 120 will no longer block the edge portion of the electrode assembly 100, and then the detection component 40 detects the electrode assembly 100 again to determine whether the deflection amount of the electrode assembly 100 meets the requirements, thereby reducing the influence of the diaphragm 120 on the detection device detecting the deflection amount of the electrode assembly 100.

[0099] The position and number of the blowing ports 22 can be adjusted as needed. For example, more blowing ports 22 can be added at different positions on both sides of the first clamping member 21 in the second direction Y to provide airflow in more directions. The shape of the blowing ports 22 can also be adjustable, for example, circular, rectangular, triangular, trapezoidal or elliptical, etc., to meet the requirements of airflow with different strengths and directions.

[0100] The above technical solution opens air outlets 22 on both sides of the first clamping member 21. Before the detection assembly 40 detects the electrode assembly 100, the air outlets 22 can blow out airflow, which can, on the one hand, blow away the diaphragm 120 suspended on the circumferential edge of the electrode assembly 100, thereby reducing the influence of the diaphragm 120 on the detection assembly 40, and, on the other hand, blow away impurities on the surface of the electrode assembly 100, thereby reducing the influence of impurities on the detection assembly 40. Therefore, the detection accuracy and reliability of the entire detection device can be further improved.

[0101] In some embodiments, the flow channel 23 includes a confluence section 231 and two diversion sections 232. One end of the confluence section 231 along its own extension direction is connected to the blowing ports 22 located on both sides of the first clamping member 21 in the second direction Y through the two diversion sections 232, and the other end of the confluence section 231 along its own extension direction is used to connect to the air source.

[0102] Exemplarily, the function of the converging section 231 is to guide the gas from the gas source to the two diverting sections 232, and the function of the diverting sections 232 is to guide the gas to the blowing ports 22 on both sides of the first clamping member 21 in the second direction Y. The converging section 231 can be arranged in a straight line to shorten the flow path of the gas and improve the gas delivery efficiency; the converging section 231 can also be arranged in a curved line to adapt to different space and layout requirements.

[0103] The combined use of the confluence section 231 and the diversion section 232 significantly reduces the complexity of the external connection pipeline between the first clamp 21 and the air source. Since there are multiple air ports 22, multiple dispersed external pipelines may be required to connect the air source to the multiple air ports 22 respectively. By setting the flow channel 23 provided inside the first clamp 21 as such a structure capable of diversion, the multiple dispersed external pipelines that may be required can be simplified into one external pipeline, which not only makes the layout of the entire detection device more compact and orderly, but also greatly reduces the total length and number of connection points of the external pipeline, which can reduce potential leakage points and reduce the risks caused by improper connection of external pipelines. At the same time, this design also makes maintenance work easier. When maintenance or repair is required, due to the simplification of the pipeline, technicians can locate and solve the problem more quickly, thereby reducing maintenance time and cost.

[0104] In general, the above technical solution can significantly improve the compactness of the layout of the detection device and reduce the maintenance cost through the effective cooperation of the converging section 231 and the diverting section 232.

[0105] In some embodiments, the diversion section 232 includes a first section 2321 and two second sections 2322, and the blowing port 22 includes a first sub-port 221 and a second sub-port 222, the first sub-port 221 and the second sub-port 222 are arranged at intervals along the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. The first section 2321 is connected between the two second sections 2322 and the converging section 231, and the two second sections 2322 are at a preset angle and respectively connect the first sub-port 221 and the second sub-port 222 to the first section 2321.

[0106] Exemplarily, the function of the first section 2321 is to distribute the gas from the confluence section 231 to the two second sections 2322. The first section 2321 can be arranged in a straight line to shorten the flow path of the gas and improve the gas transportation efficiency. The first section 2321 can also be arranged in a curved line to adapt to different space and layout requirements.

[0107] The two second sections 2322 respectively connect the first sub-port 221 and the second sub-port 222 to the first section 2321. This connection mode allows the gas to pass through the first section 2321 and the second section 2322 from the confluence section 231, and finally reach the first sub-port 221 and the second sub-port 222 uniformly. The two second sections 2322 extend from the first section 2321 respectively and form a preset angle to effectively guide the gas so that the gas can be output from the blowing port 22 along the extension direction of the second section 2322.

[0108] The two second sections 2322 at a preset angle can effectively guide the gas, so that the gas has appropriate directionality and a larger reach when reaching the diaphragm 120, which not only enables the diaphragm 120 to be blown up more evenly, improving the blowing efficiency and effect, but also reduces the risk of the airflow directly impacting the fragile part of the diaphragm 120 and causing any unnecessary stress or damage to the diaphragm 120. In addition, this design enables the airflow to be directly and effectively guided to the desired position, which helps to reduce the consumption of gas and improve the utilization efficiency of gas.

[0109] In general, the above technical solution can not only improve the blowing efficiency and effect, but also reduce the risk of airflow damaging the diaphragm 120 and improve the gas utilization efficiency by providing two second sections 2322 with a preset angle.

[0110] In some embodiments, the preset angle is an acute angle.

[0111] The acute angle design between the two second sections 2322 can make the gas output from the first sub-port 221 and the second sub-port 222 more concentrated, so that the gas can more effectively reach and blow up the diaphragm 120 farther away, further increasing the reach of the gas, thereby improving the overall effect of blowing up the diaphragm 120.

[0112] In addition, the specific angle of the preset angle can be adjusted according to the actual application environment. For example, the preset angle can be but not limited to 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc. By adjusting the size of the preset angle, the output direction and effect of the airflow can be controlled, thereby improving applicability.

[0113] In some embodiments, the grabbing component 20 includes two second clamping members 24 , which are disposed opposite to each other along the second direction Y and can move relative to each other along the second direction Y. The first direction X and the second direction Y intersect.

[0114] Exemplarily, the two second clamping members 24 cooperate with each other to clamp or release the electrode assembly 100, and the two second clamping members 24 clamp the two sides of the electrode assembly 100 in the second direction Y. In the process of the grasping member 20 grasping the electrode assembly 100 and transferring it to the carrier 10, the grasping member 20 first moves to the position of the electrode assembly 100, and the two first clamping members 21 clamp the two sides of the electrode assembly 100 in the first direction X, and the two second clamping members clamp the two sides of the electrode assembly 100 in the second direction Y. Then, the grasping member 20 clamps the electrode assembly 100 and transfers it to the preset position of the carrier 10.

[0115] The specific configuration details of the second clamping member 24 can refer to the related description of the first clamping member 21 mentioned above, which will not be repeated here.

[0116] The above technical solution further adds two second clamping members 24. The two first clamping members 21 and the two second clamping members 24 are combined with each other to realize the grasping and releasing of the electrode assembly 100. This can improve the firmness of the grasping member 20 in grasping the electrode assembly 100, and reduce the risk of the electrode assembly 100 falling off or tilting during the transfer process of the grasping member 20 clamping the electrode assembly 100, so as to further improve the reliability of the entire detection device.

[0117] In some optional embodiments, the second clamping member 24 is provided with air blowing ports 22 on both sides of the first direction X, and a flow channel 23 is provided inside the second clamping member 24, and the flow channel 23 is used to connect the air blowing ports 22 and the air source. The specific setting details of the air blowing ports 22 on the second clamping member 24 can refer to the relevant description of the air blowing ports 22 on the first clamping member 21, which will not be repeated here.

[0118] In some embodiments, the detection assembly 40 includes a first detection component 41 and a second detection component 42, wherein the first detection component 41 is disposed opposite to the carrier 10 along the first direction X and is used to detect the deflection of the electrode assembly 100 along the second direction Y. The second detection component 42 is disposed opposite to the carrier 10 along the second direction Y and is used to detect the deflection of the electrode assembly 100 along the first direction X, and the first direction X intersects with the second direction Y.

[0119] Exemplarily, the first detection component 41 is arranged opposite to the carrier 10 along the first direction X, and the first detection component 41 can detect the side of the electrode assembly 100 in the first direction X to obtain the first geometric feature of the side of the electrode assembly 100 in the first direction X, and judge whether the deflection amount m of the electrode assembly 100 in the second direction Y meets the requirements through the first geometric feature. Among them, if the electrode assembly 100 is deflected in the second direction Y, the deflection amount m of the electrode assembly 100 in the second direction Y can be reflected by the two side edges of the first geometric feature in the second direction Y. For example, when the electrode assembly 100 of the laminated structure is not deflected in the second direction Y, the two side edges of the first geometric feature in the second direction Y are substantially perpendicular to the carrying plane of the carrier 10; when the electrode assembly 100 of the laminated structure is deflected in the second direction Y, the two side edges of the first geometric feature in the second direction Y are inclined relative to the carrying plane of the carrier 10.

[0120] The first geometric feature can be understood as a two-dimensional graphic structure of the side of the electrode assembly 100 in the first direction X. As an example, the first detection component 41 is an optical camera, and the first geometric feature is the image of the side of the electrode assembly 100 in the first direction X captured by the first detection component 41.

[0121] The second detection component 42 is arranged opposite to the carrier 10 along the second direction Y. The second detection component 42 can detect the side of the electrode assembly 100 in the second direction Y to obtain the second geometric feature of the side of the electrode assembly 100 in the second direction Y, and judge whether the deflection amount n of the electrode assembly 100 in the first direction X meets the requirements through the second geometric feature. If the electrode assembly 100 is deflected in the first direction X, the deflection amount n of the electrode assembly 100 in the first direction X can be reflected by the two side edges of the second geometric feature in the first direction X. For example, when the electrode assembly 100 of the laminated structure is not deflected in the first direction X, the two side edges of the second geometric feature in the first direction X are substantially perpendicular to the bearing plane of the carrier 10; when the electrode assembly 100 of the laminated structure is deflected in the first direction X, the two side edges of the second geometric feature in the first direction X are inclined relative to the bearing plane of the carrier 10.

[0122] The second geometric feature can be understood as a two-dimensional graphic structure of the side of the electrode assembly 100 in the second direction Y. As an example, the second detection component 42 is an optical camera, and the second geometric feature is the image of the side of the electrode assembly 100 in the second direction Y captured by the second detection component 42.

[0123] The above technical solution can further improve the detection accuracy of the detection component 40 on the electrode assembly 100 by providing the first detection component 41 and the second detection component 42 to perform deflection detection on the electrode assembly 100 in different directions. In addition, the first detection component 41 and the second detection component 42 are provided separately, which is conducive to enhancing the adaptability of the detection component 40 to different working environments and conditions, and can improve the versatility and flexibility of the entire detection device.

[0124] In some embodiments, the detection assembly 40 includes two first detection components 41 and two second detection components 42. The two first detection components 41 are respectively located on both sides of the support platform 10 along the first direction X, and the two second detection components 42 are respectively located on both sides of the support platform 10 along the second direction Y.

[0125] The two first detection components 41 can respectively detect the two side surfaces of the electrode assembly 100 in the first direction X to obtain the first geometric features of the two side surfaces of the electrode assembly 100 in the first direction X, and combine the two first geometric features to comprehensively judge whether the deflection amount of the electrode assembly 100 in the second direction Y meets the requirements.

[0126] The two second detection components 42 can respectively detect the two side surfaces of the electrode assembly 100 in the second direction Y to obtain the second geometric features of the two side surfaces of the electrode assembly 100 in the second direction Y, and comprehensively judge whether the deflection amount of the electrode assembly 100 in the first direction X meets the requirements by combining the two second geometric features. In this way, the above technical solution can further improve the detection accuracy of the detection component 40 on the electrode assembly 100.

[0127] In some embodiments, the first detection component 41 includes a first camera 411 and a second camera 412, and the first camera 411 and the second camera 412 are respectively opposite to the two side edges of the carrier 10 in the second direction Y. The second detection component 42 includes a third camera 421 and a fourth camera 422, and the third camera 421 and the fourth camera 422 are respectively opposite to the two side edges of the carrier 10 in the first direction X.

[0128] Exemplarily, the first camera 411 is used to photograph one of the two side edges of the electrode assembly 100 in the second direction Y to obtain a first edge image feature, and the second camera 412 is used to photograph the other of the two side edges of the electrode assembly 100 in the second direction Y to obtain a second edge image feature, and judge whether the deflection amount of the electrode assembly 100 in the second direction Y meets the requirements through the first edge image feature and the second edge image feature. For example, when the electrode assembly 100 of the laminated structure is not deflected in the second direction Y, the first edge image feature and the second edge image feature are substantially perpendicular to the bearing plane of the bearing platform 10; when the electrode assembly 100 of the laminated structure is deflected in the second direction Y, the first edge image feature and the second edge image feature are inclined relative to the bearing plane of the bearing platform 10.

[0129] The third camera 421 is used to photograph one of the two side edges of the electrode assembly 100 in the first direction X to obtain a third edge image feature, and the fourth camera 422 is used to photograph the other of the two side edges of the electrode assembly 100 in the first direction X to obtain a fourth edge image feature, and judge whether the deflection amount of the electrode assembly 100 in the first direction X meets the requirements through the third edge image feature and the fourth edge image feature. For example, when the electrode assembly 100 of the laminated structure is not deflected in the first direction X, the third edge image feature and the fourth edge image feature are substantially perpendicular to the bearing plane of the bearing platform 10; when the electrode assembly 100 of the laminated structure is deflected in the first direction X, the third edge image feature and the fourth edge image feature are inclined relative to the bearing plane of the bearing platform 10.

[0130] Multiple cameras can respectively acquire edge image features that are directly related to the deflection detection of the electrode assembly 100, thereby reducing interference from the background or other irrelevant elements, simplifying the image processing process, and significantly reducing the amount of data to be processed when analyzing edge image features and calculating the deflection, which is beneficial to reduce the complexity of data processing, reduce computing costs and processing time, and improve data accuracy.

[0131] In general, the above technical solution can improve the overall detection efficiency of the detection device while maintaining the detection accuracy of the detection device by setting up multiple cameras and focusing on key edge image features.

[0132] In some embodiments, the detection device further includes a second control component 60 , which is communicatively connected to the gripping component 20 and the detection assembly 40 , and is configured to control the movement of the gripping component 20 according to the detection information acquired by the detection assembly 40 .

[0133] Exemplarily, the communication connection between the second control component 60 and the grasping component 20 can be a wired communication connection or a wireless communication connection. The communication connection between the second control component 60 and the detection component 40 can be a wired communication connection or a wireless communication connection. The second control component 60 can be, but is not limited to, a central control computer, a programmable logic controller, or an industrial computer.

[0134] During the process of the detection device detecting the electrode assembly 100, after the grasping component 20 places the electrode assembly 100 on the supporting platform 10, the detection component 40 detects the electrode assembly 100. When the deflection amount of the electrode assembly 100 meets the requirements, the detection component 40 generates first detection information and sends the first detection information to the second control component 60. The second control component 60 controls the grasping component 20 to move to the next workstation according to the first detection information to continue the preparation of the electrode assembly 100. When the deflection amount of the electrode assembly 100 does not meet the requirements, the detection component 40 generates second detection information and sends the second detection information to the second control component 60. The second control component 60 controls the grasping component 20 to move to the unqualified area according to the second detection information. The grasping component 20 places the unqualified electrode assembly 100 in the unqualified area for subsequent processing.

[0135] The above technical solution realizes efficient use of the detection results and automatic classification and transfer of the electrode assembly 100 by setting the second control component 60, which can further improve the overall working efficiency of the detection device.

[0136] According to some embodiments of the present application, the present application also provides a battery production equipment, including the detection device of any of the above schemes.

A flow channel 23 is provided inside the first clamping member 21, and the flow channel 23 is used to connect the air blowing ports 22 and the gas source. The flow channel 23 includes a confluence section 231 and two diversion sections 232. One end of the confluence section 231 along its own extension direction is connected to the air blowing ports 22 on both sides of the first clamping member 21 in the second direction Y through the two diversion sections 232, and the other end of the confluence section 231 along its own extension direction is used to connect the gas source. The flow dividing section 232 includes a first section 2321 and two second sections 2322, the air blowing port 22 includes a first sub-port 221 and a second sub-port 222, the first sub-port 221 and the second sub-port 222 are arranged at intervals along the third direction Z, the first section 2321 is connected between the two second sections 2322 and the converging section 231, the two second sections 2322 are at a preset angle and respectively connect the first sub-port 221 and the second sub-port 222 to the first section 2321. Among them, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0140] The measuring assembly 30 is spaced apart from the carrying platform 10, and includes a first measuring component 31 and a second measuring component 32. The first measuring component 31 is arranged opposite to the carrying platform 10 along the first direction X and is used to measure the distance between the grasping component 20 and the first measuring component 31 in the first direction X. The second measuring component 32 is arranged opposite to the carrying platform 10 along the second direction Y and is used to measure the distance between the grasping component 20 and the second measuring component 32 in the second direction Y.

[0141] The detection assembly 40 is spaced apart from the carrier 10, and the detection assembly 40 includes two first detection components 41 and two second detection components 42. The two first detection components 41 are respectively located on both sides of the carrier 10 along the first direction X and are used to detect the deflection of the electrode assembly 100 along the second direction Y. The two second detection components 42 are respectively located on both sides of the carrier 10 along the second direction Y and are used to detect the deflection of the electrode assembly 100 along the first direction X.
