Description

Technical Field

[0001] The present application relates to the field of battery detection technology, and in particular to a battery diaphragm detection device and a battery production system. Background Art

[0002] Battery separators, the insulating film between the positive and negative electrodes, are crucial for battery manufacturing, directly impacting product performance and the conversion efficiency of the final battery device. Current battery production processes often rely on manual testing for film quality (e.g., incoming material dimensions, line width, step / film thickness, 3D profile, transmittance, etc.) or lack suitable testing equipment. Furthermore, varying measurement techniques among personnel lead to poor consistency in test results, hindering subsequent automated production. Summary of the Invention

[0003] In view of the above problems, the present application provides a battery diaphragm detection device, which automatically detects the parameters of the battery diaphragm through a detection component, thereby improving the problem of large deviation in manual detection.

[0004] In a first aspect, the present application provides a battery diaphragm detection device, comprising:

[0005] Support components,

[0006] An adsorption component is connected to the support component, and the adsorption component includes an adsorption member, and the adsorption member has an adsorption surface on a side facing away from the support component, and the adsorption surface has adsorption holes, and the adsorption holes are used to adsorb the battery separator;

[0007] The detection component is arranged on the supporting component, and the position of the detection component relative to the adsorption component along the first direction is adjustable. The detection component is used to detect the size of the battery separator and / or the optical parameters of the battery separator.

[0008] The detection component is arranged on the supporting component, and the position of the detection component relative to the adsorption component along the first direction is adjustable, so that the adsorption component can receive the detection material (battery diaphragm) of the battery production system, and then adjust the position of the adsorption component relative to the detection component, so that the detection component can be moved to the designated position to detect the battery diaphragm, so as to facilitate batch testing; at the same time, compared with manual testing, the detection component can reduce the impact of human factors on the detection results when testing the same battery diaphragm, thereby improving the consistency of the detection results.

[0009] In some embodiments, the adsorption component has a plurality of nested receiving grooves on a side facing away from the supporting component, and along the height direction of the adsorption component, the bottom walls of two adjacent receiving grooves are spaced apart to form a step, and the bottom wall has an adsorption surface.

[0010] Multiple nested receiving slots can better adapt to battery separators of different sizes, shapes and other specifications. On the premise that the feeding position remains unchanged, battery separators of different specifications can be placed in receiving slots of corresponding specifications to detect battery separators of different specifications during the production process, thereby expanding the scope of application of the detection device for battery separators and improving the versatility of the device.

[0011] In some embodiments, the adsorption surface is provided with a plurality of guide holes arranged at intervals, and the adsorption component further includes a movable part, which is located below the adsorption component, and the top of the movable part has a support part, and the guide hole is slidably connected to the support part, and the support part is used to receive the battery diaphragm, and the support part is configured to retract from the outside of the guide hole into the guide hole so that battery diaphragms of different specifications can be adsorbed in different receiving grooves.

[0012] During the battery production process, the support part extends from the guide hole, which can be easily docked with the feeding equipment to receive the battery diaphragm. The movable part is then driven to shrink the support part into the guide hole, so that the battery diaphragm falls into the receiving groove. Under the premise that the feeding position of the feeding equipment remains unchanged, the battery diaphragm can be sent into the corresponding receiving groove through the contraction of the support part to complete the fixation of different battery diaphragms, facilitate the detection of battery diaphragms, and reduce the time required for adjusting the position for receiving materials due to the different positions of multiple receiving grooves, which is beneficial to improving the production efficiency of the entire battery.

[0013] In some embodiments, in the same receiving groove, there are multiple adsorption holes, and the multiple adsorption holes are arranged along the circumference of the receiving groove and are spaced apart.

[0014] Therefore, under the premise that the negative pressure in the adsorption holes remains unchanged, multiple adsorption holes can increase the adsorption area of the battery separator, so as to improve the adsorption force of the battery separator and improve the reliability of adsorption.

[0015] In some embodiments, in the same accommodating groove, the accommodating groove has two first side walls spaced apart along the first direction, and two second side walls spaced apart along the second direction, the accommodating groove has a first middle section and a second middle section, the two first side walls are at equal distances from the first middle section, the two second side walls are at equal distances from the second middle section, the first middle sections of different accommodating grooves coincide, the second middle sections of different accommodating grooves coincide, the first direction is perpendicular to the second direction, and the first direction and the second direction respectively intersect with the height direction of the adsorption component.

[0016] The setting of the first middle cross-section and the second middle cross-section can place battery separators of different specifications into the accommodating groove without changing the position of the battery separator along the first direction and the position along the second direction, that is, the unloading position of the battery separator along the first direction and the second direction is not changed, that is, battery separators of different specifications can be placed into the accommodating groove, so as to shorten the time required to adjust the unloading position of the battery separator due to the different first positioning surfaces and second positioning surfaces of different accommodating grooves, which helps to improve the efficiency of unloading.

[0017] In some embodiments, the support component also includes a first adjustment mechanism, which is arranged on the support component and connected to the adsorption component. The first adjustment mechanism is used to adjust the position of the adsorption component relative to the detection component along a first direction, and the first direction intersects with the height direction of the adsorption component.

[0018] The position of the adsorption component relative to the detection component is adjusted along the first direction by the first adjustment mechanism. When the battery diaphragm is discharged, the adsorption component can be adjusted to a position avoiding the detection component and docked with the discharge equipment to facilitate discharge. After the discharge is completed, the adsorption component can be moved along the first direction to a suitable position for detection by the detection component to facilitate detection; at the same time, it can meet the different detection requirements of the detection component (such as the position required for detecting the size and film thickness of the diaphragm may be different).

[0019] In some embodiments, the supporting component also includes a second adjustment mechanism, which is connected to the detection component. The second adjustment mechanism is used to adjust the position of the detection component relative to the adsorption component along a second direction. The second direction is perpendicular to the first direction and intersects with the height direction of the adsorption component.

[0020] When the detection component detects different parameters of the battery diaphragm, the required detection position may be different. The second adjustment mechanism adjusts the position of the detection component relative to the adsorption component, and can more flexibly condition the position of the detection component relative to the adsorption component along the second direction as needed, so that the detection component can perform more accurate detection of the battery diaphragm within the detection range.

[0021] In some embodiments, the supporting component further includes a third adjusting mechanism, which is connected to the second adjusting mechanism, and is used to adjust the position of the detection component relative to the adsorption component along the height direction of the adsorption component.

[0022] When testing battery diaphragms, the depths of different receiving grooves are different, and the heights of the battery diaphragms are also different. When testing the same parameters of different battery diaphragms, the height of the detection component relative to the battery diaphragm can be adjusted through the third adjustment mechanism. The detection component can be adjusted more accurately in the height direction through the third adjustment mechanism, so that the detection component can detect the battery diaphragm at a better detection position to improve the accuracy of the detection results.

[0023] In some embodiments, the supporting component further includes a first part, a second part and a shock absorber, the first part is located above the second part, the first part is connected to the second part through the shock absorber, and the adsorption component and the detection component are respectively arranged in the second part.

[0024] The setting of the shock absorber can reduce the impact of external environment vibration on the detection, thereby improving the accuracy of the detection results.

[0025] In some embodiments, the detection component includes a size detection module, which is used to detect the size of the battery separator; and / or, the detection component includes an optical parameter detection module, which is used to detect at least one of the transmittance, reflectivity or refractive index of the battery separator.

[0026] In this way, the detection of different parameters of the battery separator can be realized to integrate multiple detection functions, without the need for frequent transfer of battery separators and frequent replacement of detection equipment, which shortens the overall detection time and improves detection efficiency.

[0027] In some embodiments, the detection component has multiple detection parts, which are used to detect different parameters of the battery diaphragm. The battery diaphragm detection device also includes a rotating part, which is connected to the detection component. The rotating part is used to adjust the rotation of the detection component relative to the supporting part to switch different detection parts to detect the battery diaphragm.

[0028] Therefore, in the process of detecting multiple parameters of the battery diaphragm, the rotation of the detection member can be adjusted by the rotating component so that the detection head of the corresponding detection member is directed toward the battery diaphragm for detection. Compared with the method in which the detection heads of multiple detection members are all directed toward the battery diaphragm, the adjustment of the detection component along the first direction and the second direction can be reduced to improve the detection efficiency.

[0029] In some embodiments, the adsorption component also includes a first adjusting component and a second adjusting component, which are respectively driven and connected to the adsorption component. The first adjusting component is used to adjust the position of the adsorption component relative to the supporting component along the first direction, and the second adjusting component is used to adjust the position of the adsorption component relative to the supporting component along the second direction. The first direction is perpendicular to the second direction, and the first direction and the second direction respectively intersect with the height direction of the adsorption component.

[0030] In this way, the accuracy of the adsorption component in the material receiving position can be adjusted more accurately, so that the battery diaphragm can be placed more accurately at the predetermined position of the adsorption component, thereby reducing the impact of the battery diaphragm deviating from the predetermined position on the detection results, thereby improving the accuracy of the detection.

[0031] In a second aspect, the present application provides a battery production system, comprising the battery diaphragm detection device of the first aspect.

[0032] Since the battery production system includes all the technical features of the above-mentioned battery diaphragm detection device, the effects are the same as those described above and will not be repeated here.

Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0054] During the battery production process, battery separators are manually inspected, which is affected by human factors and has relatively large inspection errors. For example, when manually measuring indicators such as incoming material size and line width with measuring tools, it is difficult to ensure that the operating specifications of each measurement are completely consistent, resulting in poor inspection consistency and low manual inspection efficiency.

[0055] In view of this, the present application provides a battery diaphragm detection device, which can quickly adsorb and release the battery diaphragm through the adsorption component, so as to realize the rapid positioning and discharge of the battery diaphragm. The battery diaphragm is automatically detected by the detection component, which can reduce the influence of human factors on the detection results, thereby reducing the poor consistency and low efficiency of manual detection.

[0056] The battery diaphragm detection device of the present application can be used for, but is not limited to, detecting lithium battery diaphragms, solar cell diaphragms, etc.

[0057] For the convenience of description, the following embodiments are described by taking a battery diaphragm detection device 100 according to some embodiments of the present application as an example.

[0058] The battery separator testing device 100 includes a support member 10, an adsorption member 30, and a detection assembly 20. The adsorption member 30 is connected to the support member 10 and includes a suction member 31. The side of the adsorption member 31 facing away from the support member 10 has an adsorption surface 314. The adsorption surface 314 has adsorption holes 313 for adsorbing the battery separator. The detection assembly 20 is mounted on the support member 10 and is used to detect the dimensions and / or optical parameters of the battery separator.

[0059] The number of the adsorption surface 314 can be one or more.

[0060] The number of the adsorption holes 313 may be one or more.

[0061] As an example, the adsorption holes 313 may be connected to a negative pressure line, allowing a vacuum pump to generate negative pressure during the adsorption process to adsorb the battery separator. When there are multiple adsorption holes 313, the adsorption component 30 may have a cavity within it and an exhaust port connected to the cavity. The exhaust port is connected to a negative pressure line, which generates negative pressure within the adsorption holes 313 to adsorb the battery separator.

[0062] The supporting component 10 may be a frame or a support with a workbench.

[0063] The connection between the adsorption component 30 and the support component 10 can be a fixed connection, a rotational connection or a sliding connection.

[0064] The optical parameter includes at least one of transmittance, reflectivity or refractive index.

[0065] For example, the adsorption component 30 may be a turntable structure, rotatably connected to the support component 10. The adsorption surfaces 314 are multiple and spaced apart along the circumference of the turntable structure. By rotating the turntable structure, the adsorption surface 314 not adsorbed with the battery separator can be moved to a material receiving position to receive the material. The turntable structure is then rotated to rotate the battery separator to a designated position of the detection assembly 20 for testing. In other examples, the adsorption component 30 can slide the adsorption surface 314 to the material receiving position to receive the material, and then move the adsorption component 30 to a position to be tested to test the battery separator.

[0066] The detection component 20 is arranged on the support component 10, and the position of the detection component 20 relative to the adsorption component 30 along the first direction X is adjustable, so that the adsorption component 30 can receive the detection material (battery diaphragm) of the battery production system. By adjusting the position of the adsorption component 30 relative to the detection component 20, the detection component 20 can be moved to a specified position to detect the battery diaphragm, thereby facilitating batch testing. At the same time, compared with manual testing, the detection component 20 can reduce the influence of human factors on the test results when testing the same battery diaphragm, thereby improving the consistency of the test results.

[0067] In some embodiments, the adsorption component 31 has a plurality of nested receiving grooves 311 on the side facing away from the support component 10 , and along the height direction Z of the adsorption component 30 , the bottom walls of two adjacent receiving grooves 311 are spaced apart and form steps, and the bottom wall has an adsorption surface 314 .

[0068] The multiple nested accommodating grooves 311 refer to a bottom wall of one accommodating groove 311 being provided with another accommodating groove 311 , which are nested layer by layer along the height direction Z of the adsorption component 30 in the same manner.

[0069] For ease of illustration, of the two receiving grooves 311 along the height direction Z of the adsorption component 30, the upper receiving groove 311 is the first receiving groove, and the receiving groove below the first receiving groove is the second receiving groove. In one example, the bottom wall of the first receiving groove is connected to the side wall of the second receiving groove, and the bottom wall of the first receiving groove surrounds the second receiving groove once to form an annular step. In another example, the bottom wall of the first receiving groove surrounds the second receiving groove for less than a full circle.

[0070] The bottom wall of the receiving groove 311 can surround another receiving groove 311 provided on the bottom wall of the receiving groove 311 to form an annular step, and the upper surface of the step can serve as the adsorption surface 314. In another example, the step may not be

[0071] The structure of multiple receiving grooves 311 can better adapt to battery separators of different sizes, shapes and other specifications. On the premise that the feeding position remains unchanged, battery separators of different specifications can be placed in receiving grooves 311 of corresponding specifications to detect battery separators of different specifications during the production process, thereby expanding the scope of application of the detection device for battery separators and improving the versatility of the device.

[0072] In some embodiments, the adsorption surface 314 is provided with a plurality of guide holes 312 arranged at intervals, and the adsorption component 30 also includes a movable part 34, which is located below the adsorption component 31, and the top of the movable part 34 has a support portion 341, and the guide hole 312 is slidably connected to the support portion 341, and the support portion 341 is used to receive the battery diaphragm. The support portion 341 is configured to retract from the outside of the guide hole 312 into the guide hole 312, so that battery diaphragms of different specifications can be adsorbed in different receiving grooves 311.

[0073] The support portion 341 may be a guide post, or a support block, etc.

[0074] The guide hole 312 may be a circular hole, a square hole, a polygonal hole, etc., which is not specifically limited here.

[0075] In one example, the adsorption component 30 further includes a lifting drive component 33, which is drivably connected to the movable member 34. The lifting drive component 33 is used to drive the movable member 34 to move along the height direction Z of the adsorption component 30 to achieve extension and retraction of the support column in the guide hole 312. The lifting drive component 33 can be a cylinder, an electric push rod, or a hydraulic push rod.

[0076] As an example, there are multiple support portions 341 , and the multiple support portions 341 are arranged along the circumference of the receiving groove 311 and are spaced apart.

[0077] During the battery production process, the support part 341 extends from the guide hole 312, which can be easily docked with the feeding equipment to receive the battery diaphragm. The movable part 34 is then driven to shrink the support part 341 into the guide hole 312, so that the battery diaphragm falls into the receiving groove 311. Under the premise that the feeding position of the feeding equipment remains unchanged, the battery diaphragm can be fed into the corresponding receiving groove 311 through the shrinkage of the support part 341 to complete the fixation of different battery diaphragms, facilitate the detection of battery diaphragms, and reduce the time required for adjusting the position for receiving materials due to the different receiving positions of multiple receiving grooves 311, which is beneficial to improving the production efficiency of the entire battery.

[0078] In some embodiments, in the same receiving groove 311 , there are multiple adsorption holes 313 , and the multiple adsorption holes 313 are arranged along the circumference of the receiving groove 311 and are spaced apart.

[0079] Therefore, under the premise that the negative pressure in the adsorption holes 313 remains unchanged, the multiple adsorption holes 313 can increase the adsorption surface 314 area of the battery separator, thereby improving the adsorption force of the battery separator and improving the reliability of adsorption.

[0080] In some embodiments, in the same accommodating groove 311, the accommodating groove 311 has two first side walls 3111 spaced apart along the first direction X, and two second side walls 3112 spaced apart along the second direction Y. The accommodating groove 311 has a first middle section P1 and a second middle section P2. The two first side walls 3111 are equidistant from the first middle section P1, and the two second side walls 3112 are equidistant from the second middle section P2. The first middle sections P1 of different accommodating grooves 311 overlap, and the second middle sections P2 of different accommodating grooves 311 overlap. The first direction X is perpendicular to the second direction Y, and the first direction X and the second direction Y intersect with the height direction Z of the adsorption component 30 respectively.

[0081] In one example, the two first side walls 3111 are symmetrically arranged relative to the first mid-section P1, and the two second side walls 3112 are symmetrically arranged relative to the second mid-section P2. In other examples, the structures of the two first side walls 3111 and the structures of the two second side walls 3112 can be different, such as one first side wall 3111 having a hole and the other first side wall 3111 not having a hole, and one second side wall 3112 having a hole and the other second side wall 3112 not having a hole.

[0082] The first middle section P1 is equidistant from the two first side walls 3111 , which means that on any plane perpendicular to the third direction, the first middle section P1 is equidistant from the two first side walls 3111 , and the third direction is perpendicular to the first direction X and the second direction Y, respectively.

[0083] The setting of the first middle cross-section P1 and the second middle cross-section P2 can place battery separators of different specifications into the accommodating groove 311 without changing the position of the battery separator along the first direction X and the position along the second direction Y, that is, without changing the unloading position of the battery separator along the first direction X and the second direction Y, that is, battery separators of different specifications can be placed into the accommodating groove 311, so as to shorten the time required to adjust the unloading position of the battery separator due to the different first positioning surfaces and second positioning surfaces of different accommodating grooves 311, thereby helping to improve the efficiency of unloading.

[0084] In some embodiments, the support component 10 also includes a first adjustment mechanism 11, which is arranged on the support component 10 and connected to the adsorption component 30. The first adjustment mechanism 11 is used to adjust the position of the adsorption component 30 relative to the detection component 20 along the first direction X, and the first direction X intersects with the height direction Z of the adsorption component 30.

[0085] The first adjustment mechanism 11 may be, but is not limited to, a linear module or an electric push rod.

[0086] In one example, the first adjustment mechanism 11 may be a screw-nut adjustment mechanism, wherein the screw is rotatably connected to the support member 10, the screw is threadedly connected to the nut, and the nut is fixed to the adsorption member 30 by screws or welding. The adsorption member 30 is slidably connected to the support member 10 to serve as a guide during adjustment. The screw can be driven by a motor or rotated manually.

[0087] The position of the adsorption component 30 relative to the detection component 20 is adjusted along the first direction X by the first adjustment mechanism 11. When the battery diaphragm is discharged, the adsorption component 30 can be adjusted to a position away from the detection component 20 and docked with the discharge equipment to facilitate discharge. After the discharge is completed, the adsorption component 30 can be moved along the first direction X to a suitable position for detection by the detection component 20 to facilitate detection; at the same time, it can meet different detection requirements of the detection component 20 (for example, the position required for detecting the size and thickness of the diaphragm may be different).

[0088] In some embodiments, the support component 10 also includes a second adjustment mechanism 12, which is connected to the detection component 20. The second adjustment mechanism 12 is used to adjust the position of the detection component 20 relative to the adsorption component 30 along the second direction Y. The second direction Y is perpendicular to the first direction X, and the second direction Y intersects with the height direction Z of the adsorption component 30.

[0089] The second adjustment mechanism 12 can be a linear module or a manual drive component.

[0090] In one example, the second adjustment mechanism 12 includes a motor, an adjusting screw, and a nut. The motor serves as a power source and can accurately control the rotational movement of the adjusting screw. The adjusting screw is rotatably arranged on the support component 10. The adjusting screw cooperates with the nut. When the adjusting screw rotates, the nut moves linearly along the axial direction of the adjusting screw. This transmission method has the characteristics of high precision and strong stability, and can accurately drive the detection component 20 to achieve position adjustment. The motor can be a stepper motor or a servo motor. When manual operation is used for detection, the position of the detection component 20 along the second direction Y can be adjusted by manually rotating the adjusting screw.

[0091] When the detection component 20 detects different parameters of the battery diaphragm, the required detection position may be different. The second adjustment mechanism 12 adjusts the position of the detection component 20 relative to the adsorption component 30. The position of the detection component 20 relative to the adsorption component 30 along the second direction Y can be more flexibly adjusted as needed, so that the detection component 20 can perform more accurate detection of the battery diaphragm within the detection range.

[0092] In some embodiments, the support component 10 further includes a third adjustment mechanism 13 , which is connected to the second adjustment mechanism 12 . The third adjustment mechanism 13 is used to adjust the position of the detection component 20 relative to the adsorption component 30 along the height direction Z of the adsorption component 30 .

[0093] The third adjustment mechanism 13 can be a linear module, an electric push rod, a hydraulic push rod, etc.

[0094] When detecting battery diaphragms, the depths of different receiving grooves 311 are different, and the heights of the battery diaphragms are also different. When detecting the same parameters of different battery diaphragms, the height of the detection component 20 relative to the battery diaphragm can be adjusted by the third adjustment mechanism 13. The detection component 20 can be adjusted more accurately along the height direction Z through the third adjustment mechanism 13, so that the detection component 20 can detect the battery diaphragm at a better detection position to improve the accuracy of the detection results.

[0095] In some embodiments, the supporting component 10 also includes a first part 141, a second part 142 and a shock absorber 15. The first part 141 is located above the second part 142. The first part 141 is connected to the second part 142 through the shock absorber 15. The adsorption component 30 and the detection component 20 are respectively arranged in the second part 142.

[0096] As an example, the first portion 141 of the support component 10 includes four first columns, and the second portion 142 includes a second column that interfaces with the four columns. A shock absorber 15 is disposed between the first and second columns. The first portion 141 of the support component 10 includes a detection platform that is located atop and connected to the four first columns. In other examples, both the first and second columns may be single, or the first and second columns may be omitted, with the first portion 141 and second portion 142 configured as a support structure.

[0097] The provision of the shock absorber 15 can reduce the impact of external environmental vibration on the detection, thereby improving the accuracy of the detection result.

[0098] In some embodiments, the detection component 20 includes a size detection module, which is used to detect the size of the battery separator, and / or the detection component 20 includes an optical parameter detection module, which is used to detect at least one of the transmittance, reflectivity or refractive index of the battery separator.

[0099] The size detection module can detect parameters such as thickness, length or width of the battery separator.

[0100] The size detection module can be one or more of a point spectrum sensor, a 3D camera, a white light interferometer, a film thickness meter, or a spectral confocal probe.

[0101] The optical parameter detection module may be a spectrophotometric colorimetric module or a reflectivity measurement module, etc.

[0102] In this way, the detection of multiple parameters of the battery separator can be realized to integrate multiple detection functions, without the need for frequent transfer of battery separators and frequent replacement of detection equipment, thus shortening the overall detection time and improving detection efficiency.

[0103] In some embodiments, the detection component 20 has multiple detection parts, which are used to detect different parameters of the battery diaphragm. The battery diaphragm detection device 100 also includes a rotating part 40, which is connected to the detection component 20. The rotating part 40 is used to adjust the rotation of the detection component 20 relative to the support part 10 to switch different detection parts to detect the battery diaphragm.

[0104] The multiple detection components may be, but are not limited to, the point spectrum sensors or white light interferometers listed above.

[0105] The rotating component 40 can be a motor or a scaled turntable, the angle of which can be adjusted as needed. The turntable is equipped with multiple detection components, which are arranged at intervals along the circumference of the turntable, and the detection ends of the multiple detection components are all arranged radially outward from the turntable. After the turntable rotates to a certain angle, any detection component can be placed toward the battery diaphragm, thereby realizing switching detection of multiple detection components. The turntable can also be driven by a stepper motor or a servo motor to more accurately control the rotation angle of the turntable.

[0106] Therefore, in the process of detecting multiple parameters of the battery diaphragm, the rotation of the detection member can be adjusted by the rotating component 40 so that the detection head of the corresponding detection member is directed toward the battery diaphragm for detection. Compared with the method in which the detection heads of multiple detection members are all directed toward the battery diaphragm, the adjustment of the detection component 20 along the first direction X and the second direction Y can be reduced to improve the detection efficiency.

[0107] In some embodiments, the adsorption component 30 further includes a first adjustment component 35 and a second adjustment component 36, which are respectively driven and connected to the adsorption component 31. The first adjustment component 35 is used to adjust the position of the adsorption component 31 relative to the support component 10 along the first direction X, and the second adjustment component 36 is used to adjust the position of the adsorption component 31 relative to the support component 10 along the second direction Y. The first direction X is perpendicular to the second direction Y, and the first direction X and the second direction Y respectively intersect with the height direction Z of the adsorption component 30.

[0108] The first adjusting component 35 and the second adjusting component 36 can both be electric push rods or linear modules.

[0109] In one example, the adsorption component 30 includes a connecting member 32, which is slidably connected to the support member 10 along the first direction X. The first adjustment member 35 and the second adjustment member 36 are both arranged at the top of the base. The first adjustment member 35 includes a first abutting portion 351, a first supporting portion 352 and a first driving portion 353, and the driving end of the first driving portion 353 is connected to the first abutting portion 351. The second adjustment member 36 includes a second abutting portion 361, a second supporting portion 362 and a second driving portion 363, and the driving end of the second driving portion 363 is connected to the second abutting portion 361. The adsorption component 30 includes a lifting driving member 33, a movable member 34 and an adsorption member 31. The lifting driving member 33 is arranged at the top of the base, and the driving end of the lifting driving member 33 has a support plate, which abuts against the bottom of the movable member 34. The adsorption member 31 has a first abutting portion 351 at both ends along the first direction X, and each first abutting portion 351 is connected to a first supporting portion 352. The first supporting portion 352 is located at the bottom of the adsorption member 31 and is used to support the adsorption member 31. Each first abutting portion 351 is separately connected to a first driving portion 353. The first driving portion 353 drives the first abutting portion 351 to move along the first direction X, so that the support plate and the movable member 34 slide relative to each other, that is, the first abutting portions 351 at both ends of the adsorption member 30 along the first direction X move in the same direction of the first direction X, and the position of the adsorption plate along the first direction X can be adjusted. The adsorption member 31 has a second abutting portion 361 at both ends along the second direction Y. Each second abutting portion 361 is connected to a second supporting portion 362. The second supporting portion 362 is located at the bottom of the adsorption member 31 and is used to support the adsorption member 31. Each second abutting portion 361 is individually connected to a second driving portion 363, which drives the second abutting portion 361 to move in the second direction Y, causing the support plate and the movable member 34 to slide relative to each other. This means that the second abutting portions 361 at both ends of the adsorption component 30 along the second direction Y move in the same direction, thereby adjusting the position of the adsorption member 31 along the second direction Y. By adjusting the position of the adsorption member 31 along the first direction X and the second direction Y, the position of the adsorption member 31 can be corrected to ensure that the adsorption member 31 accurately receives the material, thereby reducing the possibility that the adsorption member 31 deviates from the predetermined position and causes the material to fail to fully fall into the receiving groove 311, thereby making the entire detection process more reliable.

[0110] In this way, the accuracy of the adsorption component 30 in the material receiving position can be adjusted more accurately, so that the battery diaphragm can be placed more accurately at the predetermined position of the adsorption component 30, thereby reducing the impact of the battery diaphragm deviating from the predetermined position on the detection results, thereby improving the accuracy of the detection.

[0111] For the convenience of description, the following embodiments are described by taking a battery diaphragm detection device 100 according to some embodiments of the present application as an example.

[0112] The battery production system includes the battery separator detection device 100 according to the above embodiments.

[0113] Since the battery production system includes all the technical features of the above-mentioned battery diaphragm detection device 100, the effects are the same as those described above and will not be repeated here.

[0114] In an optional embodiment of the battery diaphragm detection device 100 of the present application, the battery diaphragm detection device 100 includes a support component 10, an adsorption component 30, a detection assembly 20, and a rotating component 40. The support component 10 includes a bracket 14, a shock absorber 15, a first adjustment mechanism 11, a second adjustment mechanism 12, and a third adjustment mechanism 13.

The adsorption component 30 is connected to the support component 10, and the adsorption component 30 includes a base, an adsorption component 31, a movable part 34, a lifting drive component 33, a first adjustment component 35, and a second adjustment component 36. The adsorption member 31 has an adsorption surface 314 on the side facing away from the support member 10. The adsorption surface 314 has adsorption holes 313. The adsorption holes 313 are used to adsorb the battery diaphragm. The detection component 20 is arranged on the support member 10, and the detection component 20 is used to detect the parameters of the battery diaphragm. The base is slidably connected to the support member 10 along the first direction X. The top of the base is provided with a connecting member 32. The first adjustment member 35 and the second adjustment member 36 are provided on the connecting member 32. The first adjustment member 35 includes a first driving part 353, a first supporting part 352 and a first abutting part 351. The first driving part 353 and the first abutting part 351 are driven and connected. The two ends of the adsorption member 31 along the first direction X are respectively abutted with the first abutting part 351. Each first abutting part 351 is individually driven and connected to the first driving part 353. The first driving part 353 is used to drive the adsorption member 31 to move along the first direction X to adjust the position of the adsorption member 31 relative to the detection component 20 along the first direction X. Each first abutting portion 351 is connected to a first supporting portion 352, and the first supporting portion 352 is located at the bottom of the adsorbent 31 for supporting the adsorbent 31. The second adjusting component 36 includes a second driving portion 363, a second supporting portion 362 and a second abutting portion 361, and the second driving portion 363 and the second abutting portion 361 are driven and connected. The two ends of the adsorbent 31 along the second direction Y are respectively abutted with the second abutting portion 361, and each second abutting portion 361 is individually driven and connected with the second driving portion 363, and the second driving portion 363 is used to drive the adsorbent 31 to move along the second direction Y to adjust the position of the adsorbent 31 along the second direction Y relative to the detection component 20. Each second abutting portion 361 is connected to a second supporting portion 362, and the second supporting portion 362 is located at the bottom of the adsorbent 31 for supporting the adsorbent 31. The side of the adsorption member 31 facing away from the support component 10 has a plurality of nested receiving grooves 311 , and along the height direction Z of the adsorption member 30 , the bottom walls of two adjacent receiving grooves 311 are spaced apart to form a step, and the bottom wall has an adsorption surface 314 .In the same accommodating groove 311, the accommodating groove 311 has two first side walls 3111 spaced apart along the first direction X, and two second side walls 3112 spaced apart along the second direction Y. The accommodating groove 311 has a first middle section P1 and a second middle section P2. The two first side walls 3111 are equidistant from the first middle section P1, and the two second side walls 3112 are equidistant from the second middle section P2. The first middle sections P1 of different accommodating grooves 311 overlap, and the second middle sections P2 of different accommodating grooves 311 overlap. The lifting drive component 33 is located at the top of the connecting member 32 and is drivably connected to the movable member 34. The movable member 34 is located between the suction member 31 and the connecting member 32. The suction surface 314 is provided with a plurality of spaced guide holes 312. The top of the movable member 34 has a support portion 341, which is slidably connected to the guide holes 312. The support portion 341 is used to receive the battery separator. The support portion 341 is configured to retract from the outside of the guide holes 312 into the guide holes 312, so that battery separators of different specifications can be adsorbed in different receiving slots 311. The first adjustment mechanism 11 is disposed on the support member 10 and is drivably connected to the suction member 30. The first adjustment mechanism 11 is used to adjust the position of the suction member 30 relative to the detection assembly 20 along the first direction X. The second adjustment mechanism 12 is drivably connected to the detection assembly 20 and is used to adjust the position of the detection assembly 20 relative to the suction member 30 along the second direction Y. The third adjustment mechanism 13 is connected to the second adjustment mechanism 12 and is used to adjust the position of the detection assembly 20 relative to the adsorption component 30 along the height direction Z of the adsorption component 30. The second direction Y is perpendicular to the first direction X and intersects the height direction Z of the adsorption component 30. The detection assembly 20 has multiple detection components, which are used to detect different parameters of the battery separator. The battery separator testing device 100 also includes a rotating component 40, which is connected to the detection assembly 20 and is used to adjust the rotation of the detection assembly 20 relative to the support component 10 to switch between different detection components to detect the battery separator.

[0115] When placing battery separators of different specifications, the lifting drive component 33 can be used to drive the movable member 34 upward, causing the support portion 341 to extend from the guide hole 312, and the battery separator to be placed on top of the support portion 341. Because the first and second median cross-sections P1 and P2 of different receiving slots 311 overlap, battery separators of different specifications can be placed into corresponding receiving slots 311 by retracting the support portion 341 (the lifting drive component 33 drives the movable member 34 downward), without changing the placement of the battery separators. The battery separators are then adsorbed and secured by the adsorption holes 313, meeting the requirements for testing battery separators of different specifications. This also reduces the time required to adjust the adsorption component 30 or the discharge position of multiple receiving slots 311 due to misalignment of the first and / or second median cross-sections P1 and P2, thereby improving battery production efficiency. Furthermore, the arrangement of the first adjustment mechanism 11, the second adjustment mechanism 12, and the third adjustment mechanism 13 enables the detection assembly 20 to move relative to the adsorption component 30 in three different directions during the detection process. This allows for appropriate adjustment of the position of the detection assembly 20 when detecting different battery separator parameters, thereby reducing detection deviations caused by the separator deviating from the predetermined detection position and improving the accuracy of the test results. The rotating component 40 can switch between multiple detection elements to detect different battery separator parameters, reducing the time required to repeatedly adjust the position of the detection assembly 20 relative to the adsorption component 30, thereby improving detection efficiency.
