Description
Technical Field
[0001] This utility model relates to the field of comprehensive testing technology for energy storage batteries, and in particular to a comprehensive testing device for energy storage batteries. Background Technology
[0002] Energy storage batteries typically undergo multiple dimensional and appearance inspections during production line processing to confirm whether individual cells meet process requirements in terms of length, width, height, tolerance range, casing flatness, and corner defects. To achieve rapid inspection, existing production lines mostly employ continuous inspection channels, where cells sequentially pass through inspection units such as dimensional gauges and pressure structures along guide channels for automated judgment.
[0003] Existing testing methods generally adopt continuous conveying testing channels. The battery cells are tested sequentially through structures such as guides, gauges, and pressure. Since battery cells with abnormal dimensions may have out-of-tolerance or misalignment in their external dimensions, if they are allowed to come into direct contact with the scraper before their dimensional compliance is confirmed, they are prone to jamming, scratching the casing, or even blocking the channel due to excessively large battery cell width or positional deviation, which will affect the stability of subsequent testing processes. Utility Model Content
[0004] Therefore, it is necessary to provide a comprehensive testing device for energy storage batteries to address the issue that battery cells with abnormal dimensions may have out-of-tolerance or misalignment in their external dimensions. If they are allowed to come into direct contact with the scraper before their dimensional compliance is confirmed, the excessive width or positional displacement of the battery cell may cause jamming, scratching of the casing, or even blockage of the channel, affecting the stability of subsequent testing processes.
[0005] A comprehensive testing device for energy storage batteries includes: a testing platform with a testing channel fixedly installed on its top; and a comprehensive testing mechanism for pre-testing the energy storage batteries to avoid affecting subsequent testing, the comprehensive testing mechanism being disposed on one side of the testing channel; wherein the comprehensive testing mechanism includes an electric slide rail fixedly installed at the bottom of the testing channel, a conveyor plate fixedly installed at the output end of the electric slide rail, a testing warning component disposed on one side of the testing channel, and a protective testing component disposed on the other side of the testing channel.
[0006] The detection and warning component includes a support frame that is fixedly installed. The support frame is configured in an inverted U-shape. Guide frames are fixedly installed on both sides and the inner top wall of the support frame. Contact plates are slidably installed on one side of each of the multiple guide frames. Pressure detection plates are provided on the side of each of the multiple contact plates near the guide frames. The pressure detection plates are fixedly connected to the adjacent guide frames.
[0007] Multiple pulleys are rotatably mounted on the side of the contact plate away from the guide frame, and the multiple pulleys are equidistantly distributed.
[0008] Both sides of the contact plate are rounded, and the edges at both ends of the multiple pulleys are also rounded.
[0009] A first electric push rod is fixedly installed on the top of the support frame, and a marking wheel is rotatably installed on the output end of the first electric push rod, the marking wheel extending through to the top of the detection channel.
[0010] Two movable frames are provided on one side of the support frame. Both movable frames are slidably connected to the inner wall of the detection channel. A second electric push rod is fixedly installed on the inner wall of the detection channel. The output end of the second electric push rod is fixedly connected to the adjacent movable frame. The two movable frames are set in an L-shape. A grinding plate is fixedly installed on the adjacent side of the two movable frames.
[0011] The protective detection assembly includes a fixed frame that is fixedly installed on one side of the detection channel, a pressure detector that is fixedly installed on the top of the fixed frame, and a pressure plate that is provided at the output end of the pressure detector.
[0012] The top of the lower pressure plate is slidably connected to the pressure detector, and a buffer spring is fixedly installed between the lower pressure plate and the output end of the pressure detector.
[0013] Beneficial effects
[0014] 1. When the battery moves forward along the conveyor plate, the detection and warning component will first complete the external size detection. If the size is abnormal, the marking structure will be triggered immediately, so that the unqualified battery is directly identified in the channel. The battery judged to be abnormal will not enter the scraping area, fundamentally avoiding the jamming, scratches or shell damage caused by contact with the scraping parts, so that the overall detection process remains smooth and stable. After the battery enters the pressure detection, the protection detection component absorbs the impact force of the initial pressure head through the buffer mechanism, reducing the risk of indentation caused by instantaneous impact and improving the safety of battery pressure detection.
[0015] 2. During the pressing process, the pressure detector adjusts the force application speed of the pressing plate according to the force changes, so that the pressing plate gradually applies force in a slow release manner when contacting the battery cell, avoiding indentation or structural damage caused by instantaneous pressing. The buffer spring provides elastic energy absorption upon initial contact, so that the impact force is released in stages. When the reaction force on the pressing plate exceeds the set value, the buffer spring will be significantly compressed, so that the pressure detector stops pressing in time, ensuring that the pressing process is within a safe range.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] The following is combined with Figures 1-5 This invention describes a comprehensive testing device for energy storage batteries.
[0026] In one embodiment, a comprehensive testing device for energy storage batteries includes: a testing platform 100, with a testing channel 200 fixedly installed on the top of the testing platform 100; and a comprehensive testing mechanism 300, which is used to perform pre-testing on energy storage batteries to avoid affecting subsequent testing, and is disposed on one side of the testing channel 200. The comprehensive testing mechanism 300 includes an electric slide rail 310 fixedly installed at the bottom of the testing channel 200, a conveyor plate 311 fixedly installed at the output end of the electric slide rail 310, a testing warning component 320 disposed on one side of the testing channel 200, and a protective testing component 330 disposed on the other side of the testing channel 200.
[0027] In this embodiment, as the battery moves forward along the conveyor plate 311, the detection and warning component 320 prioritizes detecting the battery's external dimensions and automatically triggers a marking structure when the dimensions exceed the limit or the shape is abnormal, so that unqualified batteries can be clearly identified in the channel. Since batteries with unqualified dimensions will not continue to enter the scraping area, the problem of jamming, scratching or damage to the casing that may be caused by direct contact between out-of-tolerance batteries and scraping components is avoided, so that the detection process remains smooth and stable. The protective detection component 330 plays a buffering and protective role when the battery enters the pressure detection. By absorbing excess impact in the initial stage of the pressure head movement, it can effectively reduce the impact force caused by the instantaneous downward pressure on the battery and avoid the casing from being indented or damaged in a local structure.
[0028] Existing integrated testing devices for energy storage batteries typically consist of basic components such as a testing platform 100, a testing channel 200, and a conveying structure. The testing warning component 320 only interacts with the gauge block at the moment of cell size detection. Its marking action is completed by a light touch, which does not change the original detection accuracy of the gauge block, nor does it cause additional obstruction to the conveying path. The protective testing component 330 is located in the movement path of the pressure-up structure. It absorbs or releases energy in a buffering manner for the pressure-up action, without changing the original stroke and working mode of the pressure head, nor changing the pressure detection result. It only provides additional buffering at the initial moment of contact between the pressure head and the cell, making the action smoother. It does not change the conveying method, testing sequence, and action path of the traditional integrated testing device. It only provides auxiliary effects such as size marking, scraping control, or pressure buffering when necessary. It can improve the safety, reliability, and applicability of the device without affecting the basic testing function.
[0029] like Figure 2 , Figure 3 and Figure 4As shown, the detection warning component 320 includes a support frame 321 fixedly installed. The support frame 321 is configured in an inverted U-shape. Guide frames 322 are fixedly installed on both sides and the inner top wall of the support frame 321. Contact plates 323 are slidably installed on one side of each of the multiple guide frames 322. Pressure detection plates 325 are provided on the side of each of the multiple contact plates 323 near the guide frames 322. The pressure detection plates 325 are fixedly connected to the adjacent guide frames 322.
[0030] In this embodiment, when the battery passes the detection and warning component 320, its sidewall pushes the contact plate 323 to slide slightly within the guide frame 322. The displacement of the contact plate 323 is synchronously transmitted to the pressure detection plate 325. If the battery size is within the normal range, the pressure detection plate 325 only undergoes slight displacement, and subsequent components will not be triggered, allowing the battery to continue moving forward. When the battery width or position exceeds the preset range, the displacement of the pressure detection plate 325 increases significantly, and the warning component provided within the support frame 321 is activated, automatically marking batteries with abnormal dimensions when passing through the area.
[0031] Multiple pulleys 324 are rotatably mounted on the side of the contact plate 323 away from the guide frame 322, and the multiple pulleys 324 are equidistantly distributed.
[0032] In this embodiment, multiple pulleys 324 form rolling contact with the sidewalls of the battery cell as it passes through. This reduces friction while maintaining stable contact with the contact plate 323. When the battery cell size is normal, the pulleys 324 only rotate slightly, and the displacement of the contact plate 323 within the guide frame 322 is within the allowable range, preventing the triggering of subsequent marking mechanisms. When the battery cell size is too large or its position is off, the pulleys 324 are forced to move outward, causing the contact plate 323 to exceed its displacement limit, thus triggering an abnormal signal output by the pressure detection plate 325. The rolling adaptability of the pulleys 324 allows for size confirmation without scratching the battery cell surface.
[0033] Both sides of the contact plate 323 are rounded, and the edges of both ends of the multiple pulleys 324 are also rounded.
[0034] In this embodiment, both sides of the contact plate 323 and the end of the pulley 324 are rounded to reduce hard collisions when the battery cell enters the detection area, so that the battery cell forms a smooth guiding and rolling contact with the contact plate 323 and the pulley 324. When the battery cell size is normal, the rounded structure will guide the battery cell to pass smoothly, and the displacement of the contact plate 323 will remain within the normal range. When the battery cell size is slightly off, the pulley 324 can still move smoothly under the guidance of the rounded edge, avoiding scratching the surface of the battery cell.
[0035] A first electric push rod 326 is fixedly installed on the top of the support frame 321. A marking wheel 327 is rotatably installed on the output end of the first electric push rod 326. The marking wheel 327 extends through to the top of the detection channel 200.
[0036] In this embodiment, after receiving an abnormal size signal from the contact plate 323, the first electric push rod 326 will immediately drive the marking wheel 327 to press down, so that the marking wheel 327 lightly touches the outer surface of the battery cell from the top of the detection channel 200 and forms a shallow mark for subsequent sorting and identification. When the battery cell size is within the normal range, the first electric push rod 326 remains in a retracted state, and the marking wheel 327 is suspended and does not contact the battery cell, so as not to affect the normal passage of the battery cell.
[0037] Two movable frames 328 are provided on one side of the support frame 321. Both movable frames 328 are slidably connected to the inner wall of the detection channel 200. A second electric push rod 3210 is fixedly installed on the inner wall of the detection channel 200. The output end of the second electric push rod 3210 is fixedly connected to the adjacent movable frame 328. The two movable frames 328 are set in an L-shape. A grinding plate 329 is fixedly installed on the adjacent side of the two movable frames 328.
[0038] In this embodiment, the second electric push rod 3210 can drive two L-shaped moving frames 328 to reciprocate between the inner walls of the detection channel 200, so that the grinding plate 329 selectively extends into or exits the cell channel according to the size detection results. When the cell size is normal, the moving frames 328 retract inward under the drive of the second electric push rod 3210, so that the grinding plate 329 lightly touches the side wall of the cell and performs micro-grinding on the small burrs on the edge. When the cell size is abnormal, the moving frames 328 remain in the outward position, and the grinding plate 329 completely avoids the cell, so that there is no scratching or jamming.
[0039] like Figure 2 , Figure 3 and Figure 5 As shown, the protective detection component 330 includes a fixed bracket 331 fixedly installed on one side of the detection channel 200, a pressure detector 332 fixedly installed on the top of the fixed bracket 331, and a pressure plate 333 provided at the output end of the pressure detector 332.
[0040] In this embodiment, the pressure detector 332 can adjust the force on the pressure plate 333 in real time during the pressing action, so that the pressure plate 333 applies force gradually in a slow-release manner when contacting the battery cell, thereby avoiding indentation or structural damage to the battery cell surface due to excessively fast instantaneous pressing.
[0041] The top of the lower pressure plate 333 is slidably connected to the pressure detector 332, and a buffer spring 334 is fixedly installed between the lower pressure plate 333 and the output end of the pressure detector 332.
[0042] In this embodiment, the buffer spring 334 provides elastic suction at the initial moment when the lower pressure plate 333 contacts the battery cell, so that the pressing action of the pressure detector 332 is released step by step, thereby effectively reducing the risk of indentation caused by instantaneous impact. When the reaction force received by the lower pressure plate 333 exceeds the set range, the buffer spring 334 will generate a significant compression, so that the pressure detector 332 can identify the abnormality in time and limit the continued pressing, ensuring that the pressing process is always within a safe range.
[0043] It should be noted that the buffer spring 334 is used to form a compressible elastic connection structure between the lower pressure plate 333 and the pressure detector 332, so that the two can maintain smooth relative sliding during the pressing action and provide necessary buffer space when contacting the battery cell. The two ends of the buffer spring 334 are respectively fixed to the output ends of the lower pressure plate 333 and the pressure detector 332, so that it maintains a preset length when not under force, and can be compressed and absorb part of the instantaneous impact when the lower pressure plate 333 is subjected to a reverse force, thereby avoiding the lower pressure plate 333 from being dented or damaged due to direct rigid collision.
[0044] Working principle: The energy storage battery is first brought into the detection channel 200 by the conveyor plate 311 and moves forward steadily. When the battery passes the detection warning component 320, its side wall first forms rolling contact with multiple pulleys 324. During the rotation of the pulleys 324, the contact plate 323 on the side of the vehicle will cause slight slippage within the guide frame 322. This slippage is synchronously transmitted to the pressure detection plate 325. Since the pressure detection plate 325 and the guide frame 322 are fixedly connected, when the battery size is within the set range, the retraction of the contact plate 323 is small, and the displacement of the pressure detection plate 325 does not exceed the allowable range, so the battery can continue to move forward. When the battery width or position is too large, the contact plate 323 is forced to make a large displacement, and the pressure detection plate 325 moves to the abnormal position, causing the linkage structure inside the support frame 321 to output an abnormal command. The first electric push rod 326 is triggered and drives the marking wheel 327 to press down, lightly touching the outer wall of the battery from the top of the channel to form a shallow mark, completing the immediate identification of the abnormally sized battery cell. The battery cell with normal size will not trigger this action. After the size is confirmed, the battery enters the scraping area composed of the moving frame 328 and the grinding plate 329. The second electric push rod 3210 controls the position of the moving frame 328 based on the dimensional detection results from the previous station. If the battery size is normal, the moving frame 328 moves inward, causing the grinding plate 329 to lightly touch the edge of the battery for minor grinding of local burrs. If the battery has already been determined to be dimensionally abnormal, the moving frame 328 remains in an outward position, causing the grinding plate 329 to completely exit the channel and not contact the battery, thus preventing the out-of-tolerance battery from being scratched or stuck in this area. After continuing forward into the protection detection assembly 330, the pressure plate 333 performs pressure detection under the drive of the pressure detector 332. During the pressing process, the pressure detector 332 adjusts the force application speed according to the contact situation, so that the pressure plate 333 maintains a gradual force at the moment of contact. The buffer spring 334 between the pressure plate 333 and the pressure detector 332 further provides flexible energy absorption, so that the instantaneous impact is fully mitigated. When the pressure plate 333 encounters an abnormal reaction force, the buffer spring 334 will be significantly compressed, causing the pressure detector 332 to stop pressing down in time, ensuring that the battery is not damaged due to height deviation or local obstruction.
[0045] It should be noted that the pressure detection board, the first electric actuator, the second electric actuator, and the pressure detector mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the pressure detection board, the first electric actuator, the second electric actuator, and the pressure detector can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

Although this utility model 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 of the technical features.
