Description

Technical Field

[0001] This application relates to the field of battery testing, specifically to a battery device fixing device, testing equipment, and battery production system. Background Technology

[0002] Currently, the fixing device used to detect the geometric parameters of a workpiece positions the workpiece using multiple locating pins. When the workpiece is loaded into the fixing device for clamping and positioning, the locating holes of the workpiece need to be aligned with each locating pin. The problem is that the installation and positioning are troublesome and the operation efficiency is low. Utility Model Content

[0003] In view of the above problems, this application provides a battery device fixing device, which limits the battery device to be fixed by a support part, a first limiting part and a second limiting part, and fixes the battery device to be fixed by at least one clamping mechanism, which can accurately position and improve installation efficiency.

[0004] In a first aspect, this application provides a mounting device for a battery device, comprising:

[0005] The positioning component abuts against the battery device to be fixed along the first direction and the second direction respectively. The first direction and the second direction intersect, and the plane where the first direction and the second direction are located intersects with the height direction of the positioning component.

[0006] At least one clamping mechanism is disposed on the positioning component, and the clamping mechanism is configured to clamp the battery device to be fixed together with the positioning component.

[0007] After the positioning component supports the battery device to be fixed and abuts against it along the first and second directions respectively, the battery device to be fixed is clamped by operating the clamping mechanism to complete the positioning and clamping operation. Compared with the positioning method using positioning pins, this method can reduce the operational difficulties caused by aligning the positioning pins with the positioning holes, making the operation more convenient and efficient.

[0008] In some embodiments, the clamping mechanism includes a clamping member and a limiting member. The clamping member is rotatably connected to the positioning member and is rotatable about a first axis. The clamping member and the positioning member are configured to jointly clamp the battery device to be fixed. The limiting member is rotatably connected to the clamping member and is rotatable about a second axis. The first axis and the second axis are parallel. The limiting member and the positioning member are movably connected. The limiting member has a locked state that restricts the rotation of the clamping member relative to the positioning member, and an unlocked state that can release the restriction on the rotation of the clamping member relative to the positioning member.

[0009] The clamping component is rotatably connected to the positioning component. By operating the limiting component, the battery device to be fixed can be locked and unlocked to improve operating efficiency.

[0010] In some embodiments, the limiting member includes:

[0011] The first connector has one end rotatably connected to the clamping member and is capable of rotating about the second axis;

[0012] The adjusting member is rotatably connected to the other end of the first connecting member and can rotate about the third axis. The adjusting member is rotatably connected to the positioning member and can rotate about the fourth axis. The adjusting member has a locked state and an unlocked state. The first axis, the third axis and the fourth axis are parallel to each other.

[0013] When the adjusting element is locked, the second axis, the third axis, and the fourth axis are on the same plane.

[0014] When the adjustment component is in the unlocked state, the plane containing any two of the second, third, and fourth axes is spaced apart from the third axis.

[0015] By rotating the adjusting member, the second, third, and fourth axes can be aligned on the same plane. At this point, the first connecting member holds the clamping member in place, and the limiting member is at a "mechanical dead point," thus limiting the clamping member and preventing the battery device to be fixed from moving along the clamping direction. When the adjusting member is rotated so that the plane containing any two of the second, third, and fourth axes is spaced apart from the third, the limiting member moves away from the "mechanical dead point," releasing the clamping state of the battery device and allowing it to be detached from the battery device's fixing mechanism. Therefore, locking and unlocking of the battery device can be achieved simply by rotating the adjusting member, improving assembly and disassembly efficiency.

[0016] In some embodiments, the positioning component includes a support portion, a first limiting portion, and a second limiting portion. The support portion is used to support the battery device to be fixed, the first limiting portion is used to abut against the battery device to be fixed in a first direction, and the second limiting portion is used to abut against the battery device to be fixed in a second direction.

[0017] Therefore, the battery device to be fixed can be supported and positioned along the first and second directions. Compared with the positioning method using pin holes, the abutment method is simpler and faster to operate, which is conducive to improving operating efficiency.

[0018] In some embodiments, there are multiple second limiting portions, which are used to abut against different positions of the battery device to be fixed.

[0019] Therefore, multiple positions of the battery device to be fixed along the same side of the second direction can be limited, so that the battery device to be fixed can be more stably maintained in the preset positioning position of the battery device fixing device after clamping, thereby improving the reliability of the battery device fixing device.

[0020] In some embodiments, the support portion includes a support plane for supporting the battery device to be fixed; and / or, the first limiting portion includes a first limiting plane for limiting the battery device to be fixed along a first direction; and / or, the second limiting portion includes a second limiting plane for limiting the battery device to be fixed along a second direction.

[0021] This reduces surface dents in the battery device during positioning and clamping, thus minimizing damage to the device.

[0022] In some embodiments, the support portion includes a first support portion and a second support portion, which are spaced apart along a first direction, and are used to support the battery device to be fixed.

[0023] Compared with the method of using a large surface support, by setting a first support part and a second support part, the contact area between the support part and the battery device to be fixed can be reduced, which helps to save materials and reduce manufacturing difficulty.

[0024] In some embodiments, the clamping mechanism includes an abutment portion for clamping the battery device to be secured against the positioning member, and the battery device securing device further includes a pressure sensor.

[0025] The contact part is equipped with a pressure sensor, or the positioning component is equipped with a pressure sensor, and when the clamping mechanism is in the locked state, the pressure sensor is arranged opposite to the contact part;

[0026] The pressure sensor is used to detect the pressure of the clamping mechanism on the battery device to be fixed.

[0027] By setting a pressure sensor, it can be determined whether the clamping mechanism has pressed the battery device to be fixed to the preset position, thereby reducing the possibility that the battery device may not be fixed securely and deviate from the preset positioning position, thus improving the reliability of the battery device fixing device.

[0028] In some embodiments, the battery device fixing device further includes a position sensor disposed on the positioning component, the position sensor being used to detect the position of the battery device to be fixed along a first direction or a second direction.

[0029] When positioning the battery device to be fixed, simply place it on the support and adjust its position along the first direction. The position sensor allows for more precise detection of whether the battery device is abutting the first limiting part, facilitating position adjustment along this direction. When the clamping mechanism and the second limiting part together hold the battery device, the clamping mechanism presses it firmly against the second limiting part, completing the positioning operation. During this process, only the position of the battery device along the first direction needs to be adjusted.

[0030] Secondly, this application provides a testing device, including a testing component and a fixing device for the battery device of the first aspect;

[0031] The detection component is located above the battery assembly's mounting device and is used to detect the geometric parameters of the battery assembly to be mounted.

[0032] Since the testing equipment includes all the technical features of the fixing device of the aforementioned battery device, its effect is the same as described above, and will not be repeated here.

[0033] In some embodiments, the battery device fixing device further includes a testing platform, with positioning components disposed on top of the testing platform.

[0034] The testing platform can provide stable support for the clamping and reduce vibrations generated during the testing process, thereby improving testing accuracy.

[0035] In some embodiments, the detection device further includes a translation component that is slidably connected to the detection stage along a first direction. The translation component includes a movable connecting portion that is connected to the detection component. The translation component is configured to be driven along the first direction so that the detection component moves along the first direction.

[0036] Therefore, by sliding the translation component relative to the detection stage in the first direction, the detection component can be moved relative to the detection stage in the first direction to realize the detection of the geometric parameters of the battery device to be fixed in the first direction.

[0037] In some embodiments, the translation component includes:

[0038] A longitudinal translation mechanism is slidably connected to the detection table along the first direction;

[0039] A lateral translation mechanism is driven to connect with a longitudinal translation mechanism along a second direction. The longitudinal translation mechanism is used to drive the lateral translation mechanism to move along the second direction. The lateral translation mechanism includes a movable connecting part.

[0040] This allows the detection component to move relative to the detection stage along the second direction, thereby enabling the detection of the geometric parameters of the battery device to be fixed along the second direction, thus increasing the number of geometric parameters that can be detected and expanding the applicability of the detection equipment.

[0041] Thirdly, this application provides a battery production system, including the testing equipment of the second aspect, wherein the battery device to be fixed is a battery housing.

[0042] Since the battery production system includes all the technical features of the testing equipment mentioned in the second aspect above, and its effect is the same as described above, it will not be repeated here.

[0043] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0067] In battery manufacturing, some components of the battery assembly, such as the battery housing and cabinet, typically require inspection after manufacturing to determine their geometric parameters, such as the dimensions and contours of the battery assembly, to ensure the components are up to standard. Precise positioning of the battery assembly is crucial during inspection to minimize deviations caused by inaccurate positioning. Currently, fixing devices use multiple locating pins for precise positioning via pin-hole connections, which presents problems of inconvenient installation and low efficiency.

[0068] In view of this, this application provides a battery device fixing device. After the positioning component supports the battery device to be fixed and abuts against it along the first direction and the second direction respectively, the battery device to be fixed is clamped by operating the clamping mechanism to complete the positioning and clamping operation. Compared with the positioning method using positioning pins, it can reduce the operational difficulties caused by aligning the positioning pins with the positioning holes, making the operation convenient and more efficient.

[0069] The battery device fixing device of this application can be used in, but is not limited to, fields such as testing and welding. Specifically, it can be used as a welding fixture or a testing fixture.

[0070] For ease of explanation, please refer to the following embodiments. Figures 1-5 The following description will take a battery device fixing device 110 of some embodiments of this application as an example.

[0071] The battery device fixing device 110 includes a positioning component 10 and at least one clamping mechanism 20. The positioning component 10 abuts against the battery device 200 to be fixed along a first direction X and a second direction Y, respectively. The first direction X and the second direction Y intersect, and the plane containing the first direction X and the second direction Y intersects with the height direction Z of the positioning component 10. At least one clamping mechanism 20 is disposed on the positioning component 10, and the clamping mechanism 20 is used to clamp the battery device 200 to be fixed together with the positioning component 10.

[0072] The clamping mechanism 20 can be a manually operated mechanism, or an electrically or pneumatically operated mechanism. For example, the clamping mechanism 20 includes a cylinder and a clamping part. The clamping part is connected to the actuating end of the cylinder. The cylinder can be installed on the fixing device 110 of the battery device. The cylinder drives the clamping part to move, so that the clamping part presses the battery device 200 to be fixed against the positioning member 10 to achieve the clamping and fixing operation.

[0073] The battery device 200 to be fixed includes battery modules, battery packs, electrical boxes or cabinets, etc., which are not specifically limited here.

[0074] The clamping mechanism 20 can fix the battery device 200 to be fixed along the first direction X or the second direction Y, or it can fix the battery device 200 to be fixed along the height direction Z of the positioning component 10. For example, the clamping mechanism 20 is set on the top of the positioning component 10, and the clamping member 21 and the part of the positioning component 10 that supports the battery device 200 to be fixed together clamp and fix the battery device 200 to be fixed.

[0075] The positioning component 10 can be a single piece or an integrated structure formed by connecting multiple pieces together. The connection between multiple pieces can be welding, screw connection, riveting, etc., and the specific connection method is not limited.

[0076] The height direction Z refers to the vertical direction of the battery device's fixing device 110 when it is in use or in a natural placement state.

[0077] After the positioning component 10 supports the battery device 200 to be fixed and abuts against it along the first direction X and the second direction Y respectively, the clamping mechanism 20 is operated to clamp the battery device 200 to be fixed, thus completing the positioning and clamping operation. Compared with the positioning method using positioning pins, this method can reduce the operational difficulties caused by aligning the positioning pins with the positioning holes, making the operation more convenient and efficient.

[0078] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 5 The clamping mechanism 20 includes a clamping member 21 and a limiting member 22. The clamping member 21 is rotatably connected to the positioning member 10 and can rotate about a first axis. The clamping member 21 and the positioning member 10 are configured to jointly clamp the battery device 200 to be fixed. The limiting member 22 is rotatably connected to the clamping member 21 and can rotate about a second axis. The first axis and the second axis are parallel. The limiting member 22 is movably connected to the positioning member 10. The limiting member 22 has a locked state that restricts the rotation of the clamping member 21 relative to the positioning member 10, and an unlocked state that can release the rotation restriction of the clamping member 21 relative to the positioning member 10.

[0079] A component can be a single piece or an integrated structure formed by connecting multiple components.

[0080] As an example, please refer to Figure 2 The clamping member 21 includes a first clamping rod 211 and a second clamping rod 212, which are connected at approximately a 90° angle. Optionally, the first clamping rod 211 includes an abutting portion 2111 for abutting against the battery device 200 to be fixed, and the second clamping rod 212 is rotatably connected to the positioning member 10 via a first axis. The second clamping rod 212 is provided with a connecting hole, and a portion of the first clamping rod 211 is located in the connecting hole, which can be connected to the second clamping rod 212 by welding, riveting, or screw connection.

[0081] The connection between the limiting member 22 and the positioning component 10 can be a rotatable connection, a hook connection, or a circumferential sliding connection along the second axis.

[0082] In one example, please refer to Figure 5 The active connection is a hook-and-loop connection. Specifically, the limiting member 22 has a limiting groove 223 extending circumferentially along the second axis, and the limiting groove 223 penetrates one side surface of the limiting member 22 circumferentially along the second axis, forming a notch structure. The positioning member 10 includes a connecting part, and the connecting part has a limiting protrusion 14 that cooperates with the limiting groove 223. When the clamping member 21 and the positioning member 10 jointly clamp the battery device 200 to be fixed, the limiting protrusion 14 is located in the limiting groove 223. When unlocking is required, the limiting member 22 is rotated to disengage the limiting protrusion 14 from the limiting groove 223.

[0083] In another example, the active connection is a sliding connection. Specifically, the difference from the active connection described above is that the limiting groove 223 does not penetrate the surface of the limiting member 22 along the second axis in the circumferential direction. That is, the limiting groove 223 is an arc-shaped groove, and its circumferential dimension along the second axis is larger than the circumferential dimension of the limiting protrusion 14 along the second axis, so that the limiting protrusion 14 can move circumferentially along the second axis within the limiting groove 223. When the limiting protrusion 14 is located at one end of the limiting groove 223, it can limit the pressing member 21. When the limiting protrusion 14 is located at the other end of the limiting groove 223, the limiting member 22 is in an unlocked state.

[0084] The clamping member 21 is rotatably connected to the positioning member 10. By operating the limiting member 22, the battery device 200 to be fixed can be locked and unlocked to improve operating efficiency.

[0085] In some embodiments, please refer to Figure 2 The limiting member 22 includes a first connecting member 221 and an adjusting member 222. One end of the first connecting member 221 is rotatably connected to the pressing member 21 and can rotate about a first axis. The adjusting member 222 is rotatably connected to the other end of the first connecting member 221 and can rotate about a third axis. The adjusting member 222 is also rotatably connected to the positioning member 10 and can rotate about a fourth axis. The adjusting member 222 has a locked state and an unlocked state. The first axis, the third axis, and the fourth axis are parallel to each other.

[0086] When the adjusting member 222 is in the locked state, the second axis, the third axis and the fourth axis are on the same plane;

[0087] When the adjusting member 222 is in the unlocked state, the plane containing any two of the second axis, the third axis, and the fourth axis is spaced apart from the third axis.

[0088] By rotating the adjusting member 222, the second, third, and fourth axes can be aligned on the same plane. At this point, the first connecting member 221 holds the clamping member 21 against it, and the limiting member 22 is at a "mechanical dead point," thus limiting the clamping member 21 and preventing the battery device 200 to be fixed from moving along the clamping direction of the clamping member 21. When the adjusting member 222 is rotated so that the plane containing any two of the second, third, and fourth axes is spaced apart from the third, the limiting member 22 moves away from the "mechanical dead point," releasing the clamping state of the battery device 200 and allowing it to be detached from the battery device fixing device 110. Therefore, locking and unlocking of the battery device 200 can be achieved simply by rotating the adjusting member 222, improving assembly and disassembly efficiency.

[0089] In some embodiments, please refer to Figure 1 The positioning component 10 includes a support portion 11, a first limiting portion 12, and a second limiting portion 13. The support portion 11 is used to support the battery device 200 to be fixed, the first limiting portion 12 is used to abut against the battery device 200 to be fixed along the first direction X, and the second limiting portion 13 is used to abut against the battery device 200 to be fixed along the second direction Y.

[0090] The positioning component 10 also includes a bracket 15. The support part 11, the first limiting part 12, and the second limiting part 13 are respectively connected to the bracket 15, and can be connected by screws, welding, or riveting.

[0091] The number of each of the support part 11, the first limiting part 12, and the second limiting part 13 can be one or more.

[0092] In one example, there are two support portions 11 and two second limiting portions 13.

[0093] The contact method between the support part 11, the first limiting part 12 and the second limiting part 13 and the battery device 200 to be fixed can be surface-to-surface contact or point-to-surface contact, etc.

[0094] Therefore, the battery device 200 to be fixed can be supported and positioned along the first direction X and the second direction Y. Compared with the positioning method using pin hole cooperation, the abutment method is simpler and faster to operate, which is conducive to improving the operation efficiency.

[0095] In some embodiments, please refer to Figure 1 The number of second limiting parts 13 is multiple, and the multiple second limiting parts 13 are used to abut against different positions of the battery device 200 to be fixed.

[0096] Optionally, the number of clamping mechanisms 20 is two, and the two clamping mechanisms 20 are arranged at intervals along the height direction Z of the positioning component 10 and at intervals along the first direction X.

[0097] Therefore, multiple positions of the battery device 200 to be fixed along the same side of the second direction Y can be limited, so that the battery device 200 to be fixed can be more stably maintained in the preset positioning position of the battery device fixing device 110 after clamping, thereby improving the reliability of the battery device fixing device 110.

[0098] Therefore, clamping and positioning of the battery device 200 at two different positions can be achieved, so that the battery device 200 can be more stably maintained in the preset positioning position of the fixing device 110 after clamping, thereby improving the reliability of the fixing device 110.

[0099] In some embodiments, please refer to Figure 1 The support portion 11 includes a support plane 111 for supporting the battery device 200 to be fixed; and / or, the first limiting portion 12 includes a first limiting plane 121 for limiting the battery device 200 to be fixed along a first direction X; and / or, the second limiting portion 13 includes a second limiting plane 131 for limiting the battery device 200 to be fixed along a second direction Y.

[0100] This reduces dents on the surface of the battery device 200 during positioning and clamping, thereby minimizing damage to the battery device 200.

[0101] In some embodiments, please refer to Figure 1 The support part 11 includes a first support part and a second support part, which are spaced apart along a first direction X. The first support part and the second support part are respectively used to support the battery device 200 to be fixed.

[0102] Optionally, the upper surfaces of the first support and the second support are planes, and the two are arranged coplanarly.

[0103] Compared with the method of using a large surface support, by setting a first support part and a second support part, the contact area between the support part 11 and the battery device 200 to be fixed can be reduced, which helps to save materials and reduce manufacturing difficulty.

[0104] In some embodiments, please refer to Figure 2 The clamping mechanism 20 includes an abutment portion 2111 for clamping the battery device 200 to be fixed against the positioning member 10, and the battery device fixing device 110 also includes a pressure sensor 30.

[0105] The abutment part 2111 is provided with a pressure sensor 30; or, the positioning part 10 is provided with a pressure sensor 30, and when the clamping mechanism 20 is in the locked state, the pressure sensor 30 is arranged opposite to the abutment part 2111.

[0106] The pressure sensor 30 is used to detect the pressure of the clamping mechanism 20 pressing on the battery device 200 to be fixed.

[0107] When there are multiple pressing mechanisms 20, each pressing mechanism 20 has a pressure sensor 30 at its abutment portion 2111, or one of the multiple pressing mechanisms 20 may have a pressure sensor 30; or, at least one pressing mechanism 20 may have a pressure sensor 30 at the position of its corresponding positioning component 10.

[0108] In one example, the abutment portion 2111 and the second limiting portion 13 of the clamping mechanism 20 are spaced apart along the second direction Y, and the abutment portion 2111 and the second limiting portion 13 together clamp the battery device 200 to be fixed. The pressure sensor 30 is disposed on either the abutment portion 2111 or the second limiting portion 13.

[0109] By setting the pressure sensor 30, it can be determined whether the clamping mechanism 20 has pressed the battery device 200 to be fixed to the preset position, thereby reducing the possibility that the battery device 200 to be fixed may not be fixed properly and deviate from the preset positioning position, thereby improving the reliability of the battery device fixing device 110.

[0110] In some embodiments, please refer to Figure 1 The battery device fixing device 110 also includes a position sensor 40, which is disposed on the positioning component 10 and is used to detect the position of the battery device 200 to be fixed along the first direction X or the second direction Y.

[0111] As an example, when the positioning component 10 includes a support portion 11, and the support portion 11 includes a first support portion and a second support portion, the position sensor 40 may be installed in one of the first support portion and the second support portion.

[0112] As an example, the position sensor 40 is used to detect the position of the battery device 200 to be fixed along the first direction X. The number of the first limiting part 12 is one. When the battery device 200 to be fixed and the first limiting part 12 are not fully in contact along the first direction X, the position sensor 40 can generate a non-contact trigger signal. According to the trigger signal, an alarm message is issued through the alarm device. The operator can adjust the battery device 200 to be fixed according to the alarm message for convenient operation.

[0113] When positioning the battery device 200 to be fixed, simply place it on the support 11 and adjust its position along the first direction X. The position sensor 40 allows for more precise detection of whether the battery device 200 is abutting against the first limiting part 12, facilitating position adjustment along the first direction X. When the clamping mechanism 20 and the second limiting part 13 together hold the battery device 200, the clamping mechanism 20 then presses the battery device 200 against the second limiting part 13, completing the positioning operation. During positioning, only the position of the battery device 200 along the first direction X needs to be adjusted.

[0114] For ease of explanation, please refer to the following examples. Figures 1-6 The following description will be based on a detection device 100 according to some embodiments of this application.

[0115] The testing device 100 includes a testing component 140 and a fixing device 110 for the battery device in the above embodiments. The testing component 140 is located above the fixing device 110 for the battery device and is used to test the geometric parameters of the battery device 200 to be fixed.

[0116] The geometric parameters include one or more of the shape parameters (dimensions), contour parameters (profile), or positional tolerance parameters (parallelism, perpendicularity, etc.) of the battery device 200 to be fixed.

[0117] The structure of the detection component 140 is the same as that of the probe of the coordinate measuring machine, which is existing technology. The specific structure will not be described in detail.

[0118] Since the testing equipment 100 includes all the technical features of the fixing device 110 of the battery device described above, its effect is the same as described above, and will not be repeated here.

[0119] In some embodiments, please refer to Figure 6 The battery device fixing device 110 also includes a testing platform 120, with the positioning component 10 disposed on the top of the testing platform 120.

[0120] Optionally, the testing station 120 includes a marble platform.

[0121] The testing stage 120 can provide stable support for the clamping and reduce vibrations generated during the testing process, thereby improving testing accuracy.

[0122] In some embodiments, please refer to Figure 6The testing device 100 also includes a translation component 130, which is slidably connected to the testing stage 120 along the first direction X. The translation component 130 includes a movable connecting part, which is connected to the testing component 140. The translation component 130 is configured to be driven along the first direction X so that the testing component 140 moves along the first direction X.

[0123] Optionally, the translation component 130 can be slidably connected to the testing table 120 via guide rails and sliders. Specifically, guide rails are provided on both opposite sides of the testing table 120, with the length direction of the guide rails being the same as the first direction X. Sliders are slidably connected to the guide rails. The translation component 130 is generally a gantry structure, including two connecting parts, which are connected to the sliders. A lead screw is connected to the translation component 130, and a lead screw is rotatably connected to the testing table 120. The lead screw is threadedly connected to the lead screw, and the lead screw is driven by a motor, with its axis being the same as the first direction X. By driving the rotation of the lead screw by the motor, the translation component 130 can move along the first direction X.

[0124] Therefore, by sliding the translation component 130 relative to the detection stage 120 along the first direction X, the detection component 140 can be moved relative to the detection stage 120 along the first direction X, so as to realize the detection of the geometric parameters of the battery device 200 to be fixed along the first direction X.

[0125] In some embodiments, please refer to Figure 6 The translation component 130 includes a longitudinal translation mechanism 1301 and a lateral translation mechanism 1302. The longitudinal translation mechanism 1301 is slidably connected to the detection stage 120 along a first direction X. The lateral translation mechanism 1302 is drivenly connected to the longitudinal translation mechanism 1301 along a second direction Y. The longitudinal translation mechanism 1301 is used to drive the lateral translation mechanism 1302 to move along the second direction Y. The lateral translation mechanism 1302 includes a movable connecting part.

[0126] In one example, the longitudinal translation mechanism 1301 includes a connecting frame and a driving component. The connecting frame is slidably connected to the detection stage 120 along the first direction X. The specific connection structure can be, but is not limited to, the connection method of the guide rail and slider described above. The driving component is mounted on the connecting frame. The driving component can be, but is not limited to, an electric push rod or a linear module, etc.

[0127] Therefore, the detection component 140 can be moved relative to the detection stage 120 along the second direction Y to detect the geometric parameters of the battery device 200 to be fixed along the second direction Y, thereby increasing the number of geometric parameters that can be detected and expanding the applicability of the detection equipment 100.

[0128] For ease of explanation, the following embodiments use a battery production system from some embodiments of this application as an example.

[0129] The battery production system includes the testing equipment 100 of the above embodiments, and the battery device 200 to be fixed is a battery box.

[0130] Since the battery production system includes all the technical features of the testing equipment 100 in the above embodiments, the effect is the same as described above, and will not be repeated here.

[0131] In an alternative embodiment of the battery device fixing device 110, please refer to Figures 1-3 The battery device fixing device 110 is used to clamp and position the battery housing. The fixing device 110 includes a positioning component 10, a pressure sensor 30, a position sensor 40, and two clamping mechanisms 20. The positioning component 10 includes a first limiting part 12, two support parts 11, and four second limiting parts 13. Both support parts 11 support the battery housing. The first limiting part 12 limits the battery housing along a first direction X, and the second limiting parts 13 limit the battery housing along a second direction Y. The two support parts 11 are spaced apart along the first direction X, and the four second limiting parts 13 abut against different positions of the battery device 200 to be fixed. Each clamping mechanism 20 clamps the battery housing together with multiple second limiting parts 13. One of the two support parts 11 is equipped with a position sensor 40, which detects the position of the battery housing along the first direction X. The support part 11 includes a support plane 111 for supporting the battery housing. The first limiting part 12 includes a first limiting plane 121 for limiting the battery case along the first direction X. The second limiting part 13 includes a second limiting plane 131 for limiting the battery case along the second direction Y.

[0132] The clamping mechanism 20 includes a clamping member 21 and a limiting member 22. The clamping member 21 is rotatably connected to the positioning member 10 and can rotate around a first axis. The clamping member 21 and the positioning member 10 are configured to jointly clamp the battery box. The limiting member 22 is rotatably connected to the clamping member 21 and can rotate around a second axis. The first axis and the second axis are parallel.

[0133] The limiting member 22 includes a first connecting member 221 and an adjusting member 222. One end of the first connecting member 221 is rotatably connected to the pressing member 21 and can rotate about a first axis. The adjusting member 222 is rotatably connected to the other end of the first connecting member 221 and can rotate about a third axis. The adjusting member 222 is also rotatably connected to the positioning member 10 and can rotate about a fourth axis. The adjusting member 222 has a locked state and an unlocked state. The first, third, and fourth axes are parallel to each other. When the adjusting member 222 is in the locked state, the second, third, and fourth axes are on the same plane; when the adjusting member 222 is in the unlocked state, the plane containing any two of the second, third, and fourth axes is spaced apart from the third. The pressing member 21 includes an abutment portion 2111. A pressure sensor 30 is installed on one of the abutment portion 2111 and the second limiting portion 13. The pressure sensor 30 is used to detect the pressure of the pressing mechanism 20 pressed against the battery box.

[0134] By rotating the adjusting member 222, the second, third, and fourth axes can be aligned on the same plane. At this point, the first connecting member 221 holds the clamping member 21 against it, and the limiting member 22 is at a "mechanical dead point," thus limiting the clamping member 21 and preventing the battery case from moving along the clamping direction of the clamping member 21. When the adjusting member 222 is rotated so that the plane containing any two of the second, third, and fourth axes is spaced apart from the third, the limiting member 22 moves away from the "mechanical dead point," releasing the clamping state of the battery case and allowing it to be detached from the battery device's fixing device 110. Therefore, the clamping mechanism 20, pressure sensor 30, and position sensor 40 enable rapid positioning and clamping of the battery case, improving operational efficiency.

[0135] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
