Description

Technical Field

[0001] The present application relates to the technical field of battery detection, and in particular to a detection platform and a battery tray detection system. Background Art

[0002] The battery tray inspection tooling can be used to perform air tightness testing on the battery tray. In some cases, the battery tray's quick-change tooling air tightness testing platform uses a one-to-one method to perform air tightness testing, so different testing platforms need to be designed for different battery tray inspection tooling, which is very troublesome and also increases the processing cost. Utility Model Content

[0003] The present application provides a detection platform and a battery tray detection system, aiming to improve the problem that the battery tray detection platform cannot be used for a variety of battery tray detection tooling.

[0004] In order to achieve the above technical effects, a technical solution adopted by the present application is: providing a detection platform, the detection platform is used to install a battery tray detection tooling, the battery tray detection tooling includes a detection base for supporting the battery tray and a detection component for detecting the battery tray, and the detection platform includes:

[0005] Basic platform;

[0006] A sliding support platform is connected to the base platform, and the sliding support platform is used to be detachably connected to the detection base;

[0007] A clamping platform is arranged outside the base platform, and the clamping platform is used to be detachably connected to the detection component;

[0008] The pressure driving mechanism is arranged on the outside of the base platform, and the pressure driving mechanism is connected to the pressing platform for driving the pressing platform to press or move away from the battery tray.

[0009] The example of the present application adopts a sliding support table to connect the inspection base of the battery tray inspection tooling, and connects the inspection component of the battery tray inspection tooling through a clamping platform. By detachably connecting the inspection base to the sliding support table, and detachably connecting the clamping platform to the inspection component, the battery tray inspection tooling can be replaced as needed, so that the inspection platform can be used for different battery tray inspection tools, thereby reducing the inspection cost through the reuse of the inspection platform.

[0010] Wherein, a first positioning member is arranged on the sliding support platform, and the first positioning member is used for positioning and connecting with the detection base.

[0011] In this example, by setting the first positioning member to position the detection base, the detection base can be quickly aligned on the sliding support table. On the one hand, the sliding support table can be quickly positioned with the detection base, and on the other hand, the stability of the detection base on the sliding support table can be improved.

[0012] Wherein, a second positioning member is arranged on the sliding support platform, and the second positioning member is used for being detachably connected to the detection base.

[0013] The second positioning member in this example is used to connect with the detection base so that the detection base can maintain a stable state relative to the sliding support table. On the one hand, when the sliding support table moves relative to each other, the relative displacement of the detection base can be reduced. On the other hand, the problem of misalignment of the detection base during the detection process can be reduced.

[0014] The base platform has a first support position and a second support position, the sliding support platform is movably connected to the base platform between the first support position and the second support position, and the clamping platform is arranged opposite to the first support position. In this example, by adopting a movable sliding support platform, it is convenient to install the battery tray detection tooling on the sliding support platform, so that the sliding support platform can be moved to the clamping platform position, thereby facilitating the loading and unloading of the detection platform.

[0015] The direction from the first support position to the second support position is the first direction, a slide rail is arranged on the base platform, the slide rail is extended along the first direction, a slider is arranged on the sliding support platform, and the slider is slidably connected to the slide rail. The slide rail and the slider in this example slide together to improve the directionality and controllability of the movement of the sliding support platform.

[0016] The base platform is provided with a first limiter, which is used to stop the sliding support platform at a side away from the second support position when the sliding support platform is in the first support position. The first limiter is used to limit the moving range of the sliding support platform, so that when the sliding support platform moves to the first support position, it can be blocked at the first support position, so that the sliding support platform can be better aligned with the clamping platform, thereby improving the controllability of the battery tray detection tooling.

[0017] The base platform is provided with a second limiter, which is used to stop the sliding support platform at a side away from the first support position when the sliding support platform is in the second support position. The second limiter is used to limit the moving range of the sliding support platform, so that when the sliding support platform moves to the second support position, it can be blocked at the second support position, so that the sliding support platform can be better aligned with external equipment such as hoisting equipment.

[0018] The testing platform also includes:

[0019] The gas storage tank is connected to the basic platform, and the gas storage tank is used to be detachably connected to the detection component.

[0020] The gas tank in this example can be used to supply gas to the detection component to improve the gas flow stability of the output gas and reduce the problem of reduced detection accuracy caused by unstable gas flow.

[0021] The base platform is provided with a support block, which is used to support the side of the sliding support platform away from the pressing platform. The support block in this example can be used to support the sliding support platform, so that when the sliding support platform is on the base platform, the force on the sliding support platform is dispersed, and the deformation of the sliding support platform caused by stress concentration is reduced.

[0022] There are multiple support blocks, which are arranged at intervals. The multiple support blocks in this example can be used to disperse the forces acting on the sliding support platform to improve the anti-deformation performance of the sliding support platform.

[0023] The clamping platform is provided with a plurality of third positioning members, which are arranged at intervals and are used to be positioned and connected with the detection assembly. The third positioning member in this example is used to position the detection assembly so that the detection assembly can be aligned with the clamping platform to facilitate the control of the operation of the detection assembly.

[0024] There are multiple pressure drive mechanisms, and the multiple pressure drive mechanisms are arranged at intervals. In this example, by arranging multiple pressure drive mechanisms, the uniformity of the force on the pressing platform can be improved.

[0025] The testing platform also includes:

[0026] The foreign body detection mechanism is connected to the basic platform.

[0027] The foreign object detection mechanism in this example can be used to detect foreign objects that enter above the sliding support table to reduce the risk of personnel being squeezed during the pressing process.

[0028] The testing platform also includes:

[0029] The operating table is connected to the basic platform. The operating table is connected to the pressure driving mechanism by electrical signals. The operating table is also used to connect to the battery tray detection tooling by electrical signals.

[0030] In this example, an operating console is integrated on the basic platform to facilitate staff to operate nearby, thereby improving the convenience of the operation process.

[0031] The operating table is provided with a plurality of detection processes, and the operating table is used to control the operation of at least one of the pressure driving mechanism and the battery tray detection tooling according to the detection process.

[0032] The operating table in this example is set with multiple preset inspection processes. When replacing different battery tray inspection tooling, the operating table can control the operation of the battery tray inspection tooling and the pressure drive mechanism according to the preset inspection process. Then, different inspection processes can be used for different battery tray inspection tooling to perform inspection operations, so as to expand the scope of application of the inspection platform.

[0033] The operating table is foldably connected to the base platform. In this example, a foldable operating table is used, and the operating table can be folded on the base platform when needed, thereby reducing the overall volume of the detection platform.

[0034] The present application also proposes an example of a battery tray detection system, including:

[0035] Gas detectors;

[0036] For example, in any of the above-mentioned detection platforms, the gas detector is used to detect the battery tray of the detection platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Batteries are the power source of new energy vehicles. They are mainly composed of battery cells, modules, electrical systems, thermal management systems, tray shells and battery management systems. The battery assembly process is a key step in the production of battery packs, and its process level is directly related to the power performance and safety performance of electric vehicles. Therefore, an important performance must be considered at the beginning of battery design - airtightness. As the protective shell of the battery, the battery tray has more stringent requirements in terms of airtightness.

[0051] In some cases, the battery tray inspection tool is a special device for leak detection of battery tray air tightness. The battery tray inspection tool fills the interior of the test piece with compressed air or nitrogen of a specified pressure. It can determine whether the test piece is leaking and the size of the leak based on the attenuation value of its internal pressure. It can be combined with different leak detection methods (differential pressure method, flow method, etc.) according to customer needs for semi-automatic or fully automatic detection. Due to the different types of battery trays, different battery tray inspection tools are required for different battery trays. In some cases, different inspection platforms are required for different battery tray inspection tools, which greatly increases the inspection cost and is not conducive to the co-line testing of multiple products.

[0052] The example of the present application proposes an example of a detection platform, the detection platform is used to install a battery tray detection tool, the battery tray detection tool includes a detection base for supporting the battery tray and a detection component for detecting the battery tray, the detection platform includes a base platform, a sliding support platform, a clamping platform and a pressure drive mechanism, the sliding support platform is connected to the base platform, the sliding support platform is used to be detachably connected to the detection base; the clamping platform is arranged on the outside of the base platform, the clamping platform is used to be detachably connected to the detection component, the pressure drive mechanism is arranged on the outside of the base platform, the pressure drive mechanism is connected to the clamping platform, and is used to drive the clamping platform to press or move away from the battery tray. In the detection platform in this example, the sliding support platform can be detachably connected to the detection base, and the clamping platform can be detachably connected to the detection component, so that the battery tray detection tool can be replaced as needed, and can be used for the detection of different types of battery trays.

[0053] The detection platform in the example of the present application can be used in a battery tray detection system. The battery tray detection system includes a gas detector and the detection platform in the above example. The gas detector can be used to locate the leakage point of the battery tray for subsequent processing.

[0054] Please join us Figure 1 and Figure 2 In some examples, the battery tray inspection tool 700 includes a detection base 710 for supporting the battery tray and a detection assembly 720 for inspecting the battery tray. The inspection platform includes a basic platform 100, a sliding support platform 200, a clamping platform 300 and a pressure driving mechanism 320. The sliding support platform 200 is connected to the basic platform 100, and the sliding support platform 200 is used to be detachably connected to the inspection base 710; the clamping platform 300 is arranged on the outside of the basic platform 100, and the clamping platform 300 is used to be detachably connected to the inspection assembly 720. The pressure driving mechanism 320 is arranged on the outside of the basic platform 100, and the pressure driving mechanism 320 is drivingly connected to the clamping platform 300, and is used to drive the clamping platform 300 to press or move away from the battery tray.

[0055] The battery tray inspection tool 700 can be used to inspect the air tightness of the battery tray. The battery tray inspection tool 700 includes a inspection base 710 and an inspection component 720 .

[0056] The detection base 710 may be a component for supporting the battery tray on the battery tray detection tool 700, and the detection base 710 may be used to connect to the bottom wall of the battery tray. The detection base 710 in the example of the present application may be a flat plate structure, and a filling block corresponding to the shape of the bottom wall of the battery tray may be provided on the detection base 710, so as to fill the gap between the battery tray and the detection base 710, thereby saving the time of inflation.

[0057] The detection component 720 is used to block the air inlet, air outlet, and air leakage port on the battery tray, and can also be used to input air or nitrogen into the battery tray during the battery tray testing process to perform air tightness testing on the battery tray. In this example, a sealing fixture can be set on the battery tray to be tested, and the detection component 720 is used to cooperate with the sealing fixture to seal the air inlet, air outlet, and air leakage port on the battery tray to be tested, and the test gas can be input into the battery tray through the sealing fixture. The detection component 720 in the example of the present application can be detachably connected to the detection base 710, which means that the detection component 720 and the detection base 710 are separately arranged, and the detection component 720 can be directly placed on the detection base 710, and can also be connected to the detection base 710, and can be removed from the detection base 710, so as to Figure 2 As shown in the example, the detection assembly 720 is disposed above the detection base 710 .

[0058] Please refer to Figure 3 , Figure 4 and Figure 5 The basic platform 100 may be the bottom support structure of the detection platform. The basic platform 100 may be a fixed platform fixedly arranged in the battery tray detection system, or a mobile platform movably arranged in the battery tray detection system. In the example of the present application, the basic platform 100 is movably arranged in the battery tray detection system as an example. Rollers may be arranged on the basic platform 100 to move the basic platform 100 when necessary.

[0059] Please continue to combine Figure 6 and Figure 7 , the sliding support platform 200 is connected to the base platform 100, which means that the sliding support platform 200 is arranged on the base platform 100. In the example of the present application, the sliding support platform 200 can be arranged above the base platform 100. The sliding support platform 200 is used to be detachably connected to the detection base 710, which means that the sliding support platform 200 can be connected to the detection base 710, and the detection base 710 can be detached from the sliding support platform 200. In the example of the present application, the battery tray detection tool 700 can be placed on the sliding support platform 200 as a whole, and then the detection base 710 of the battery tray detection tool 700 can be connected to the sliding support platform 200.

[0060] The clamping platform 300 is arranged on the outside of the base platform 100, and the clamping platform 300 can be used to press the battery tray to perform air tightness detection on the battery tray. In the example of the present application, the clamping platform 300 can also be used to be detachably connected to the detection component 720, so as to block the air inlet, air outlet and air leakage port on the battery tray through the detection component 720. The clamping platform 300 in this example can be suspended on the outside of the base platform 100, and the clamping platform 300 can also be connected to the base platform 100 through an intermediate connector such as a bracket 310.

[0061] The pressure drive mechanism 320 is arranged on the outside of the base platform 100, which means that the pressure drive mechanism 320 can be connected to the base platform 100, and the pressure drive mechanism 320 may not be connected to the base platform 100. The pressure drive mechanism 320 is drivingly connected to the clamping platform 300, which means that the pressure drive mechanism 320 can be used to drive the clamping platform 300 to move in a preset direction. The pressure drive mechanism 320 in the example of the present application is used to drive the clamping platform 300 to move toward or away from the battery tray. When performing airtightness detection, the clamping platform 300 can press the battery tray. When the battery tray needs to be removed, the pressure drive mechanism 320 can drive the clamping platform 300 to move away from the battery tray, thereby facilitating the loading and unloading of the battery tray. Optionally, in this example, the detection base 710 is detachably connected to the detection assembly 720, and when the pressure drive mechanism 320 drives the clamping platform 300 to move, the detection assembly can move synchronously.

[0062] When performing air tightness testing on the battery tray, the sliding support platform 200 and the pressing platform 300 are arranged opposite to each other, the battery tray is located on the sliding support platform 200, and the pressing platform 300 exerts a pressing effect on the battery tray on the outside of the battery tray. The detection component 720 on the pressing platform 300 blocks the air inlet, air outlet and air leakage of the battery tray to facilitate air tightness testing. After the test is completed, the pressure drive mechanism 320 can drive the pressing platform 300 away from the battery tray to facilitate the removal of the battery tray from the sliding support platform 200. In this example, by detachably connecting the detection component 720 to the clamping platform 300 and detachably connecting the detection base 710 to the sliding support platform 200, on the one hand, the battery tray detection tooling 700 can be installed separately, thereby improving the convenience of installing the battery tray detection tooling 700; on the other hand, since the battery tray detection tooling 700 can be disassembled and replaced, when used for different battery tray detections, the same detection platform can be used, and only the battery tray detection tooling 700 corresponding to the battery tray needs to be replaced. There is no need to set up a separate detection platform for each battery tray, so that multiple products can be tested on the same line, thereby reducing the cost of battery tray detection.

[0063] In order to facilitate the loading and unloading of the battery tray, the sliding support platform 200 in the example of the present application can be movably connected to the base platform 100. When the positions of the sliding support platform 200 and the pressing platform 300 are staggered, the loading and unloading of the battery tray can be facilitated. In some examples, the sliding support platform 200 is set at a preset position on the base platform 100, and the pressing platform 300 and the pressure drive mechanism 320 are movably connected to the base platform 100, so that the pressing platform 300 and the pressure drive mechanism 320 can be moved away from the preset position on the base platform 100, so as to facilitate the removal of the battery tray on the sliding support platform 200.

[0064] In this example, after the battery tray inspection tool 700 is installed on the inspection platform, a standard specimen can be installed on the battery tray inspection tool 700. The standard specimen is a battery tray that has been tested and meets the standards. The battery tray inspection tool 700 is self-inspected for air tightness using the standard specimen. If it is found during the air tightness self-inspection that the air tightness of the battery tray inspection tool 700 does not meet the requirements, the battery tray inspection tool 700 is replaced.

[0065] Please refer to Figures 4 to 7 In some examples, a first positioning member 210 is provided on the sliding support platform 200, and the first positioning member 210 is used to be positioned and connected with the detection base 710. The positioning connection means that the first positioning member 210 can be used to position the detection base 710, so that the detection base 710 can be quickly aligned on the sliding support platform 200. The first positioning member 210 is a positioning mechanism provided on the sliding support platform 200. The first positioning member 210 in the example of the present application can be a positioning pin, a positioning groove or other structure capable of positioning the detection base 710. In this example, by setting the first positioning member 210, it can be used to quickly position the detection base 710. On the one hand, it can limit the relative movement of the detection base 710 on the sliding support table 200 to improve the stability of the battery tray during detection, thereby helping to improve the accuracy of detection; on the other hand, when replacing different battery tray detection fixtures 700, the detection base 710 can be quickly positioned by the first positioning member 210, so as to facilitate rapid alignment of the battery tray detection fixture 700 to improve detection efficiency; on another hand, the first positioning member 210 can be used to improve the repeatability of each installation of the detection base, which is convenient for subsequent positioning of the detection base.

[0066] In some examples, a second positioning member 220 is provided on the sliding support table 200, and the second positioning member 220 is used to be detachably connected to the detection base 710. The second positioning member 220 in this example is used to be detachably connected to the detection base 710, and the second positioning member 220 can be a bolt, a buckle or other intermediate connecting member that can connect the sliding support table 200. In this example, the second positioning member 220 is taken as a bolt as an example. After the battery tray detection tool 700 is placed on the sliding support table 200, the detection base 710 is detachably connected to the sliding support table 200 by bolts. After the current type of battery tray is detected, the detection base 710 can be removed to facilitate replacement of a different battery tray for detection.

[0067] In some examples, the base platform 100 has a first support position 140 and a second support position 150 , the sliding support platform 200 is movably connected to the base platform 100 between the first support position 140 and the second support position 150 , and the clamping platform 300 is arranged opposite to the first support position 140 .

[0068] The base platform 100 has a first support position 140 and a second support position 150, wherein the first support position 140 and the second support position 150 can be two adjacent positions, the first support position 140 and the second support position 150 can also be spaced apart, and the first support position 140 and the second support position 150 can partially overlap. For the convenience of description, the first support position 140 and the second support position 150 are used as examples in the present application. Figure 3 Optionally, the direction from the first support position 140 to the second support position 150 is the first direction 1a. It can be understood that the first direction 1a in the example of the present application can be bidirectional, and the first direction 1a can also be the direction from the second support position 150 to the first support position 140.

[0069] The sliding support platform 200 is movably connected to the base platform 100, which means that the sliding support platform 200 can move along a preset trajectory on the base platform 100. In the example of the present application, the sliding support platform 200 is movably connected to the base platform 100 between the first support position 140 and the second support position 150, so that the sliding support platform 200 can move between the first support position 140 and the second support position 150.

[0070] The clamping platform 300 is arranged relative to the first support position 140, which means that the clamping platform 300 corresponds to the position of the first support position 140. When the pressure drive mechanism 320 drives the clamping platform 300 to move relatively, the clamping platform 300 can move in a direction close to or away from the first support position 140. After the battery tray detection tool 700 is installed on the sliding support platform 200, the sliding support platform 200 can be moved to the first support position 140, and the pressure drive mechanism 320 drives the clamping platform 300 to move in a direction close to the first support position 140. At this time, the detection component 720 of the battery tray detection tool 700 can be connected to the clamping platform 300 to perform an airtightness test on the battery tray. After the test is completed, the pressure drive mechanism 320 can drive the clamping platform 300 to move away from the first support position 140, so as to remove the battery tray from the detection base 710.

[0071] In this example, by movably connecting the sliding support platform 200 to the base platform 100, it is convenient to install the battery tray detection tool 700 and the battery tray, and it is also convenient to install and position the clamping platform 300 and the pressure drive mechanism 320.

[0072] In some examples, a slide rail 110 is disposed on the base platform 100 , and the slide rail 110 is extended along the first direction 1 a . A slider 230 is disposed on the sliding support platform 200 , and the slider 230 is slidably connected to the slide rail 110 .

[0073] The slide rail 110 is used to form a track extending along the first direction 1 a on the base platform 100 . The cross section of the slide rail 110 in this example may be T-shaped, circular, conical or other shapes.

[0074] The slider 230 is connected to the sliding support platform 200, and the slider 230 is used to slide with the slide rail 110, so that the sliding support platform 200 can be directed along the extension direction of the slide rail 110. In this example, the slide rail 110 is extended along the first direction 1a, so that the sliding support platform 200 can be directed along the first direction 1a, thereby enabling the sliding support platform 200 to have a preset motion trajectory, thereby improving the directionality and stability of the movement of the sliding support platform 200.

[0075] In some examples, a first stopper 112 is disposed on the base platform 100 , and the first stopper 112 is used to stop and limit the sliding support platform 200 at a side away from the second support position 150 when the sliding support platform 200 is at the first support position 140 .

[0076] The first limiter 112 is disposed on the base platform 100. In this example, the first limiter 112 may be a limiter pin, a limiter block or other structure that can be used to block the sliding support platform 200. When the sliding support platform 200 in this example is at the first support position 140, the first limiter 112 is stopped and limited at the side of the sliding support platform 200 away from the second support position 150, so as to limit the maximum range of movement of the sliding support platform 200 in the direction of the first support position 140 by the first limiter 112. In this example, the number of the first limiter 112 may be one, or the number of the first limiter 112 may be multiple.

[0077] In some examples, a second position-limiting member 113 is disposed on the base platform 100 , and the second position-limiting member 113 is used to stop and limit the sliding support platform 200 at a side away from the first support position 140 when the sliding support platform 200 is at the second support position 150 .

[0078] The second limiter 113 is arranged on the base platform 100. In this example, the second limiter 113 can be a limiter pin, a limiter block or other structure that can be used to produce a blocking effect on the sliding support platform 200. In this example, the second limiter 113 can be arranged relative to the first limiter 112 along the first direction 1a. When the sliding support platform 200 is in the second support position 150, the second limiter 113 is stopped and limited to the side of the sliding support platform 200 away from the first support position 140, so as to limit the maximum range of movement of the sliding support platform 200 in the direction of the second support position 150 by the second limiter 113. In this example, the number of the second limiter 113 can be one, and the number of the second limiter 113 can also be multiple. Optionally, the number of the first limiter 112 is multiple, and the multiple first limiters 112 and the multiple second limiters 113 are respectively arranged on both sides of the first direction 1a in a one-to-one correspondence.

[0079] In some examples, the detection platform also includes a gas tank 120, which is connected to the base platform 100, and the gas tank 120 is used to be detachably connected to the detection component 720. The gas tank 120 is used to store detection gases such as nitrogen. The gas tank 120 in this example can be used to supply gas to the detection component 720. In this example, by using the gas tank 120 to supply gas, the gas pressure of the detection component 720 can be maintained by the gas tank 120. When performing airtightness testing, the air pressure during the detection process can be kept stable, thereby reducing the problem of distortion of the detection result caused by unstable air pressure. The gas tank 120 in this example is detachably connected to the detection component 720, which means that the gas tank 120 can be connected to the detection component 720 through a pipeline, and at least one of the pipeline and the gas tank 120 or the detection component 720 is detachable. When the battery tray detection tooling 700 is disassembled, the connection between the detection component 720 and the gas tank 120 can be disconnected. Optionally, the sliding support platform 200 is movably connected to the base platform 100 between the first support position 140 and the second support position 150, and the clamping platform 300 is arranged on the outside of the first support position 140, so that the clamping platform 300 can maintain a relatively stable position on the base platform 100, so as to keep the gas tank 120 in a relatively stable position of the clamping platform 300. When the clamping platform 300 and the detection component 720 are detachably connected, it can be more convenient to connect and fix the detection component 720 and the gas tank 120 to each other.

[0080] In some examples, the base platform 100 is provided with a support block 130, and the support block 130 is used to support the side of the sliding support platform 200 away from the pressing platform 300. The support block 130 in this example can be a convex block, convex rib or rib convexly provided on the base platform 100. Optionally, the support block 130 can be a supporting structure provided at the first support position 140; in some examples, the support block 130 can be provided at the first support position 140 and the second support position, respectively. For the convenience of description, the following takes the support block 130 provided at the first support position 140 as an example. When the sliding support platform 200 is located at the first support position 140, the support block 130 can be supported on the side of the sliding support platform 200 away from the pressing platform 300 to disperse the force applied to the sliding support platform 200 and reduce the deformation of the sliding support platform 200. Optionally, the base platform 100 is provided with the slide rail 110 described in the above example, and the slide support platform 200 is provided with the slider 230 described in the above example. The number of the slide rails 110 may be multiple, and the support blocks 130 may be provided between adjacent slide rails 110 .

[0081] In some examples, there are multiple support blocks 130, and the multiple support blocks 130 are arranged at intervals. The support blocks 130 in this example can be supported at intervals on the side of the sliding support platform 200 away from the pressing platform 300 to disperse the force applied to the sliding support platform 200 and reduce the possibility of deformation of the sliding support platform 200. Optionally, the multiple support blocks 130 in this example can be arranged at intervals along the first direction, and the multiple support blocks 130 can also be distributed in a matrix or irregularly.

[0082] In some examples, a plurality of third positioning members 330 are provided on the clamping platform 300, and the plurality of third positioning members 330 are arranged at intervals, and the third positioning members 330 are used to position and connect with the detection assembly 720. The third positioning member 330 in this example can be a positioning pin, a positioning screw or other structure that can be used to position the detection assembly 720 provided on the clamping platform 300. In this example, when the battery tray detection tool 700 is placed on the sliding support table 200, and the sliding support table 200 is located at a position relative to the clamping platform 300, the clamping platform 300 can be driven by the pressure drive mechanism 320 to move toward the sliding support table 200, so that the clamping platform 300 is close to the detection assembly 720. After the detection assembly 720 is positioned and connected by the third positioning member 330, when the pressure drive mechanism 320 drives the clamping platform 300 to move away from the sliding support table 200, the detection assembly 720 can be synchronously moved away from the detection base 710. The battery tray to be tested is placed on the testing base 710, and the pressure drive mechanism 320 drives the clamping platform 300 to press the battery tray for air tightness testing; after the test is completed, the pressure drive mechanism 320 drives the clamping platform 300 to move away from the testing base 710 to facilitate the removal of the battery tray to be tested. The third positioning member 330 in this example can facilitate the positioning of the testing component 720 and the clamping platform 300, so that the testing component 720 can be installed at a preset position on the clamping platform 300; when used for different battery tray testing fixtures 700, the third positioning member 330 can be used to quickly position the testing component 720, thereby facilitating the rapid adaptation of the clamping platform 300 to different battery tray testing fixtures 700 to improve the adaptability of the testing platform.

[0083] In some examples, there are multiple pressure driving mechanisms 320 , and the multiple pressure driving mechanisms 320 are arranged at intervals.

[0084] The pressure drive mechanism 320 in this example is used to drive the clamping platform 300 to move along a preset trajectory. The pressure drive mechanism 320 can be a cylinder, a motor or other mechanism that can be used to drive the clamping platform 300 to move in a directional manner along a preset trajectory. The multiple pressure drive mechanisms 320 in this example are arranged at intervals to disperse the forces generated by the multiple pressure drive mechanisms 320, so that the clamping platform 300 can generate a more uniform force on the battery tray to be tested. On the one hand, it can reduce the detection error caused by uneven force, and on the other hand, it can reduce the possibility of deformation of the clamping platform 300. Optionally, in this example, a guide mechanism such as a guide column can be set on the base platform 100 to further limit the moving trajectory of the clamping platform 300.

[0085] In some examples, the detection platform also includes a foreign body detection mechanism 400 connected to the base platform 100, and the foreign body detection mechanism 400 can be used to detect whether there is a foreign body entering the space between the clamping platform 300 and the sliding support platform 200. The foreign body detection mechanism 400 in this example can be installed on the base platform 100. Optionally, a bracket 310 is provided on the base platform 100, and the foreign body detection mechanism 400 can be installed on the bracket 310, and the bracket 310 can also be used to install the clamping platform 300 and the pressure drive mechanism 320 described in the above example. The foreign body detection mechanism 400 can be used to detect whether the arm or other parts of the staff enter the gap between the clamping platform 300 and the sliding support platform 200. When a foreign body enters between the clamping platform 300 and the sliding support platform 200, the pressure drive mechanism 320 can be forced to shut down. The foreign body detection mechanism 400 in the example of this application can be a grating, an infrared sensor or other structure that can be used to detect foreign bodies. There may be multiple foreign body detection mechanisms 400, and multiple foreign body detection mechanisms 400 may be arranged at intervals on the base platform 100. In this example, a bracket 310 may be arranged on the base platform 100, and the bracket 310 may have at least four corners, and the foreign body detection mechanisms 400 may be arranged at the four corners of the bracket 310, respectively.

[0086] In some examples, the inspection platform further includes an operating table 500 , which is connected to the base platform 100 , and the operating table 500 is electrically connected to the pressure drive mechanism 320 , and the operating table 500 is also used to electrically connect to the battery tray inspection tooling 700 .

[0087] The operating table 500 can be used to control the operation of the pressure drive mechanism 320 to control the movement of the clamping platform 300. The operating table 500 can also be used to control the operation of the battery tray detection tool 700 to perform air tightness detection on the battery tray to be tested. The operating table 500 in this example can be connected to the battery tray detection tool 700 through a wire, an adapter or other structure to control the operation of the battery tray detection tool 700. The operating table 500 in this example is connected to the basic platform 100, which means that the operating table 500 can be installed on the basic platform 100 to control the pressure drive mechanism 320 and the battery tray detection tool 700 nearby.

[0088] In some examples, the operating table 500 is provided with a plurality of detection processes, and the operating table 500 is also used to control the operation of at least one of the pressure drive mechanism and the battery tray detection tooling according to the detection process. The detection process in this example may be a preset process corresponding to the battery tray detection tooling. In some examples, the operating table 500 may be provided with a control button, and the control button may be a physical button, for example, a button provided on the operating table 500, and each button on the operating table 500 may correspond to a detection process of a battery tray detection tooling. For different battery tray detection tools, different buttons may be selected on the operating table 500 to execute different detection processes. The detection process in this example may be an existing operation process pre-stored in the operating table 500. Optionally, the operating table 500 may be provided with a control panel, and the control button may also be a capacitive button provided on the control panel, etc.

[0089] In some examples, the operating station 500 controls the operation of the pressure drive mechanism according to the detection process, including controlling at least one of the start and stop, operation time and travel of the pressure drive mechanism. In this example, for different battery trays, different preset detection processes can be selected to control the operation of the pressure drive mechanism.

[0090] In some examples, the operating table 500 is foldably connected to the base platform 100. The foldable means that the operating table 500 can move relative to the base platform 100. When the operating table 500 moves relative to the base platform 100, the operating table 500 can be folded to a preset position on the base platform 100 for storage, thereby reducing the volume of the detection platform and reducing the obstruction to the staff.

[0091] Please refer to Figure 8 The present application also proposes an example of a battery tray detection system, including a gas detector 600 and a detection platform as described in any of the above examples, wherein the gas detector 600 is used to perform gas detection on a battery tray detection tool 700 of the detection platform.

[0092] The gas detector 600 may be a handheld gas detector 600 or a gas detector 600 installed on a detection platform. The gas detector 600 may be used to detect the gas leakage point of the battery tray to determine the specific leakage location.

[0093] In this example, after the battery tray is tested for air tightness, if a gas leakage problem is found in the battery tray, the specific leaking part on the battery tray can be located by using the gas detector 600.

[0094] Please refer to Figures 1 to 8The present application discloses an example of a testing platform, which can be used to perform airtightness testing on a battery tray. The testing platform can be used to install a battery tray testing tool 700, wherein the battery tray testing tool 700 includes a testing base 710 and a testing component 720, wherein the testing base 710 is used to support the battery tray, and the testing component 720 can be used to seal and test the battery tray; the testing platform includes a basic platform 100, a sliding support platform 200, a clamping platform 300 and a pressure driving mechanism 320, the sliding support platform 200 is connected to the basic platform 100, and the sliding support platform 200 is used to be detachably connected to the testing base 710; the clamping platform 300 is arranged on the outside of the basic platform 100, and the clamping platform 300 is used to be detachably connected to the testing component 720, and the pressure driving mechanism 320 is arranged on the outside of the basic platform 100, and the pressure driving mechanism 320 is drivingly connected to the clamping platform 300, and is used to drive the clamping platform 300 to press or move away from the battery tray. After the battery tray inspection tool 700 is placed on the inspection platform, the inspection base 710 and the sliding support platform 200 can be connected and fixed to each other through the first positioning member 210, so that the inspection base 710 maintains a preset position on the sliding support platform 200; the pressure drive mechanism 320 drives the clamping platform 300 to move toward the sliding support platform 200, so that the clamping platform 300 is close to the inspection component 720, and the inspection component 720 is connected to the clamping platform 300 through the third positioning member 330; the basic platform 100 has a first support position 140 and a second support position 150, and the sliding support platform 200 can be movably connected to the basic platform 100 between the first support position 140 and the second support position 150. When the sliding support platform 200 is in the first support position 140, the sliding support platform 200 can be connected to the basic platform 100 through the second positioning member 220, so that the sliding The support table 200 remains in a relatively fixed state at the first support position 140; the battery tray testing tool 700 is adapted to the battery tray. After the installation of the battery tray testing tool 700 is completed, a battery tray with a standard sample that has been tested and meets the airtightness standard can be installed on the testing base 710 to perform an airtightness self-test on the battery tray testing tool 700. After determining that the battery tray testing tool 700 meets the airtightness requirements, the standard sample is taken out; the battery tray to be tested is placed on the testing base 710, and the pressure drive mechanism 320 can drive the clamping platform 300 to approach the battery tray to be tested, so that the detection component 720 cooperates with the battery tray to be tested, so as to perform an airtightness test on the battery tray to be tested.
