Description

Technical Field

[0001] This utility model relates to the field of battery cover plate testing technology, and in particular to a rapid clamping fixture and its testing device for water testing of cover plates. Background Technology

[0002] In the field of new energy battery manufacturing, the sealing performance of the battery cover is one of the key factors determining battery safety and lifespan. Air tightness testing, or leak detection, is an essential inspection step in the production process. Currently, in addition to using high-precision helium gas spectrometers for leak detection, water testing is widely adopted due to its intuitiveness and low cost.

[0003] In the prior art, such as the utility model patent with publication number CN219455400U, a water testing fixture for a new energy battery cover is disclosed. This fixture typically includes a base, guide posts, a positioning plate, and a sliding block. The sliding block has a groove for placing the cover, and a cylinder drives the sliding block to press against the positioning plate, aligning the various components on the cover (such as positive and negative terminals, explosion-proof valves, and injection holes) with the corresponding openings on the positioning plate. During testing, the operator drips water into these openings and then fills the sealed cavity formed by the cover and the sliding block with gas at a certain pressure. The sealing performance at the corresponding location is determined by observing whether bubbles are generated in the water.

[0004] However, this existing fixture has a significant drawback: after testing, water accumulated on the surface of the positioning plate, especially in the recessed areas such as the injection hole, cannot be effectively drained. If the cylinder is directly driven to separate the sliding block from the positioning plate at this point, the remaining water will flow freely due to the loss of restraint. This not only wets the equipment and work surface, making cleaning inconvenient and affecting work efficiency, but more seriously, the water may seep into the pneumatic components or guide mechanism of the fixture, causing corrosion, damage, or electrical short circuits, shortening the equipment's lifespan, and posing safety hazards. Utility Model Content

[0005] This utility model provides a quick-clamping fixture and its testing device for water testing of cover plates, which can solve the following problems existing in the prior art: After the test is completed, the water accumulated on the surface of the positioning plate, especially in the recessed areas such as the injection hole, cannot be effectively drained. If the cylinder is directly driven at this time to separate the sliding block from the positioning plate, this residual water will flow freely due to the loss of restraint.

An inclined guide plate is fixedly arranged at the end of the first guide plate, the inclined guide plate is inclined in a direction away from the worktable, and a second guide plate is fixedly arranged at the other end of the inclined guide plate, the second guide plate being parallel to the worktable. The lifting mechanism also includes a translation mechanism, which drives the base to reciprocate on the worktable.

[0009] Preferably, the driving end of the translation mechanism is fixedly provided with an adjustment plate, and adjustment frames are fixedly provided on both sides of the base. An adjustment motor is fixedly provided on one side of the adjustment plate, and the driving end of the adjustment motor passes through the adjustment plate and is fixedly connected to the adjustment frame.

[0010] Preferably, an air inlet pipe is connected to one side of the water inspection support, and the air inlet pipe is connected to the positioning groove; One side of the workbench is also equipped with an air supply pipe, which is connected to an air pump. The air inlet pipe is at the same height as the air supply pipe.

[0011] Preferably, a water storage tank is also provided on one side of the bottom of the workbench for collecting and treating the test water poured into the water inlet and the channel.

[0012] Preferably, the top plate is also provided with a sealing plate for sealing the water inlet, and L-shaped brackets are fixedly arranged at both ends of the sealing plate. The other end of the L-shaped bracket is fixed to the support shaft, and both ends of the support shaft are fixed to the top plate by limiting seats. The top plate is also provided with a rotating part, which is used to drive the support shaft to rotate.

[0013] Preferably, the rotating part includes gears symmetrically fixedly arranged at both ends of the support shaft, and spur racks for meshing with the gears are symmetrically arranged on both sides of the worktable, and the spur racks on both sides are fixed to the worktable by a connecting frame; The water storage tank is also provided with symmetrically arranged arc-shaped teeth on both sides for meshing with gears.

[0014] Preferably, the end of the second guide plate away from the first guide plate is also fixedly provided with an arc-shaped frame for rolling contact with the guide wheel.

[0015] Preferably, L-shaped baffles are fixedly arranged at both ends of the top plate, and screws are spirally arranged in the L-shaped baffles.

[0016] This utility model provides a quick-clamping fixture and its testing device for water testing of cover plates, which has the following beneficial effects: 1) In the initial state, this utility model drives the base to move above the first guide plate via a translation mechanism. The guide plate supports the guide wheels, and the distance between the pressure plate and the top plate is at its maximum at this time. This facilitates the robot arm to load the cover plate body to be inspected into the positioning groove. After loading, the translation mechanism drives the base to move towards the second guide plate. Based on the inclined guide plate, the lifting rod can be driven to rise via the guide wheels. During the rise of the lifting rod, the pressure plate is driven simultaneously to achieve the effect of pressing the cover plate body with the sealing ring in the through groove and the positioning groove. Correspondingly, after the water inspection is completed, the translation mechanism can drive the base to reset, and the pressure plate can be separated from the top plate to facilitate subsequent unloading and a new round of loading. Based on this, this utility model does not need to set up other servo devices to adjust the height of the base. With the translation of the base, the lifting and lowering of the pressure plate can be automatically adjusted, which not only reduces costs but also improves synchronization and stability. 2) In the water testing process, the opening of the water inlet faces upward. After the water test is completed, the adjustment frame can be rotated 180 degrees by adjusting the motor so that the opening of the water inlet faces downward. This allows the test water in the water inlet and the channel to be automatically discharged under gravity, avoiding the phenomenon of the test water flowing freely after the test is completed, so that the test water can be collected and treated again. 3) After the water test is completed, the cover plate body of this utility model can be driven by the translation mechanism to continue moving away from the first guide plate along the second guide plate. The gear can mesh with the rack and pinion, and then drive the support shaft to rotate through the gear to adjust the sealing plate to be placed on the water inlet to achieve a seal. As the adjustment motor drives the adjustment frame to rotate, when the water inlet is about to rotate to the point where the opening is completely downward, the arc-shaped tooth meshes with the gear and drives the support shaft to rotate in the opposite direction to open the water inlet, so that the test water can be discharged from the water inlet into the water storage tank.

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] Example 1

[0021] like Figures 1 to 3 as well as Figures 5-7As shown in the figure, the present invention provides a quick clamping fixture for water testing of cover plates, including a base 301, on which at least two sets of guide rods 302 are fixedly arranged, and the other end of the guide rods 302 is fixedly connected to the top plate 308; specifically, in this embodiment, four sets of guide rods 302 are provided and are symmetrically arranged at both ends of the base 301.

[0022] In this embodiment, a pressure plate 305 is also provided between the base 301 and the top plate 308. The pressure plate 305 is slidably sleeved on each guide rod 302. The clamping fixture also includes a lifting mechanism, which is used to drive the pressure plate 305 to slide and lift on the guide rod 302. Specifically, in this embodiment, a water testing fixture for sealing the cover plate body 7 is provided between the pressure plate 305 and the top plate 308. It can be explained that, in this embodiment, when performing water testing on the cover plate body 7, the lifting mechanism first drives the pressure plate 305 to descend and separate it from the top plate 308. Then, the cover plate body 7 to be tested is placed at the water testing fixture. The lifting mechanism then drives the pressure plate 305 to rise, applying force directly and evenly to the water testing fixture. This compresses the cover plate body 7 and the sealing ring within the entire water testing fixture in one go. The sealing ring seals the side edge of the cover plate body 7, preventing gas leakage or water entry into the water testing fixture from the side edge of the cover plate body 7 during subsequent air-filled water testing, thus ensuring the quality of subsequent water testing.

[0023] In one embodiment of this invention, the water testing fixture includes a water testing support 306 fixed to the pressure plate 305. The water testing support 306 has a positioning groove 3 for embedding into the cover plate body 7. The fixture also includes a water testing sealing seat 307 fixed to the bottom of the top plate 308. The water testing sealing seat 307 has a through groove 312 corresponding to the positioning groove 3. The top plate 308 has a water inlet 309 communicating with the through groove 312. It can be noted that in this embodiment, when performing water testing on the cover plate body 7, a loading robot transfers the cover plate body 7 into the positioning groove 3 on the water testing support 306. The positioning groove 3 positions the cover plate body 7 to ensure the stability of subsequent water testing. Then, a lifting mechanism drives the pressure plate 305 upwards. The pressure plate 305 lifts the cover plate body 7 so that the through groove 312 can cover the cover plate body 7. At the same time, sealing rings can be installed in the positioning groove 3 and the through groove 312. Through the pressure of the pressure plate 305, the cover plate body 7, the through groove 312 and the sealing rings in the positioning groove 3 are pressed together to ensure the sealing of the side edge of the cover plate body 7. At this time, the positive and negative terminals, the explosion-proof valve and the liquid injection hole on the cover plate body 7 are located in the through groove 312. After the air is supplied to the positioning groove 3 of the water inspection support 306, water is added to the through groove 312 through the water inlet 309. Then, the positive and negative terminals, the explosion-proof valve and the liquid injection hole of the cover plate body 7 are observed to detect whether air bubbles are generated, and then it is determined whether there is any leakage in each part of the cover plate body 7. If no air bubbles are generated, it means that the cover plate body 7 has no leakage.

[0024] In this embodiment, the lifting mechanism includes a lifting cylinder fixed on the base 301, and the driving end of the lifting cylinder is fixed to the pressure plate 305. It can be noted that in this embodiment, when driving the pressure plate 305 to rise or fall, the lifting cylinder can be activated, and the pressure plate 305 can be driven to slide on the guide rod 302 through the lifting cylinder. Correspondingly, the lifting cylinder in this embodiment can also be replaced by an electric cylinder or a hydraulic cylinder to meet the actual application requirements. This embodiment does not limit its specific model and structure.

[0025] Example 2

[0026] Based on Example 1, please refer to Figures 1-2 as well as Figures 4-5A detection device for water testing of a cover plate includes a workbench 1. The lifting mechanism includes a lifting rod 303 fixed to the bottom of a pressure plate 305. A telescopic spring 304 is provided on the lifting rod 303. One end of the telescopic spring 304 is fixed to a base 301, and the other end is fixed to the lifting rod 303. The end of the lifting rod 303 away from the pressure plate 305 slides through the base 301. A guide wheel 507 is rotatably arranged at the bottom end of the lifting rod 303. A first guide plate 503 parallel to the workbench 1 is fixedly arranged on the workbench 1, and the position of the first guide plate 503 corresponds to the guide wheel 507. An inclined guide plate 501 is fixedly arranged at the end of the first guide plate 503, and the inclined guide plate 501 is inclined in a direction away from the workbench 1. A second guide plate 5 is fixedly arranged at the other end of the inclined guide plate 501, and the second guide plate 5 is parallel to the workbench 1. The lifting mechanism also includes a translation mechanism 2, which drives the base 301 to... The workbench 1 reciprocates. It can be explained that in the initial state, the base 301 is driven to move above the first guide plate 503 by the translation mechanism 2. The guide plate 503 can support the guide wheel 507. At this time, the distance between the pressure plate 305 and the top plate 308 is the largest, which makes it easier for the robot to load the cover body 7 to be inspected into the positioning groove 3. After the loading is completed, the translation mechanism 2 drives the base 301 to move towards the second guide plate 5. Based on the setting of the inclined guide plate 501, the lifting rod 303 can be driven to rise through the guide wheel 507. During the rise of the lifting rod 303, the pressure plate 305 can be driven to rise simultaneously to achieve the effect of pressing the cover body 7 with the through groove 312 and the sealing ring in the positioning groove 3. Correspondingly, after the water inspection is completed, the translation mechanism 2 can drive the base 301 to reset, and the pressure plate 305 can be separated from the top plate 308 to facilitate subsequent unloading and a new round of loading. Based on this, this embodiment does not require setting up other servo devices to adjust the height of the base 301. As the base 301 moves horizontally, the lifting and lowering of the pressure plate 305 can be automatically adjusted, which not only reduces costs but also improves synchronization and stability.

[0027] Furthermore, the translation mechanism 2 in this embodiment can be a synchronous belt drive mechanism or a lead screw drive mechanism. This embodiment does not limit this to any particular type, as long as it meets the actual application requirements.

[0028] As one possible implementation method of this embodiment, after the water test is completed, in order to automatically discharge the water in the water inlet 309 and the channel 312, the driving end of the translation mechanism 2 is fixedly provided with an adjusting plate 506, and the two sides of the base 301 are respectively fixedly provided with adjusting frames 504. An adjusting motor 505 is fixedly provided on one side of the adjusting plate 506, and the driving end of the adjusting motor 505 passes through the adjusting plate 506 and is fixedly connected to the adjusting frame 504. It can be noted that during the water test, the opening of the water inlet 309 is upward. After the water test is completed, in this embodiment, the adjusting motor 505 can drive the adjusting frame 504 to rotate 180 degrees so that the opening of the water inlet 309 is downward, so that the test water in the water inlet 309 and the channel 312 can be automatically discharged under the action of gravity, avoiding the phenomenon of the test water flowing arbitrarily after the test is completed, so that the test water can be collected and processed again.

[0029] It should be noted that since the positive and negative terminals, explosion-proof valve and liquid injection hole on the cover plate body 7 are all irregular structures and have dead corner gaps, it is difficult to use adsorption to suck out the detection water in the water inlet 309 and the through groove 312. However, this embodiment uses a pouring method, which can effectively pour out all the water without leaving any residue.

[0030] In addition, you can refer to Figure 3 The water inspection support 306 is connected to an air inlet pipe 310 on one side, which is connected to the positioning groove 3. The workbench 1 is also provided with an air supply pipe 311 on one side, which is connected to an air pump. The air inlet pipe 310 and the air supply pipe 311 are at the same height. It can be explained that when the translation mechanism 2 drives the base 301 to move to the second guide plate 5, the air inlet pipe 310 and the air supply pipe 311 are connected. When the water pump is started, water can be transported from the air supply pipe 311 and the air inlet pipe 310 to the positioning groove 3 to achieve the effect of inflation, which is convenient for subsequent leak detection.

[0031] As one implementation method of this embodiment, please refer to Figures 1-3 as well as Figures 6-8 A water storage tank 102 is also provided on one side of the bottom of the workbench 1 to collect and treat the test water poured into the water inlet 309 and the through channel 312. Specifically, when the water inlet 309 is rotated to face downward, the test water inside can be discharged into the water storage tank 102 under the action of gravity for collection, so as to facilitate subsequent unified treatment.

[0032] It should also be noted that when the water inlet 309 is not rotated to face downwards, for example, if it is rotated 90 degrees, in order to prevent the test water from flowing out prematurely and thus failing to be collected, in this embodiment, the top plate 308 is also provided with a sealing plate 4 for sealing the water inlet 309. L-shaped brackets 401 are fixedly arranged at both ends of the sealing plate 4, and the other end of the L-shaped brackets 401 is fixed to the support shaft 402. Both ends of the support shaft 402 are fixed to the top plate 308 through limiting seats 403. The top plate 308 is also provided with a rotating part, which is used to drive the support shaft 402 to rotate. It can be noted that in this embodiment, during the testing of the cover plate body 7, the rotating part is adjusted... The sealing plate 4 is separated from the water inlet 309 to facilitate the addition of test water to the water inlet 309 and the observation of whether air bubbles are generated. When the test is completed and the test water needs to be discharged, in this embodiment, the rotating part can first drive the support shaft 402 to rotate. The support shaft 402 drives the sealing plate 4 to rotate synchronously through the L-shaped bracket 401, so that the sealing plate 4 can cover the water inlet 309 to achieve the effect of sealing the water inlet 309. Correspondingly, when the water inlet 309 is about to rotate to the point where the opening is completely downward, the rotating part drives the sealing plate 4 to rotate away from the water inlet 309 in advance to open the water inlet 309 and facilitate the discharge of test water.

[0033] Specifically, the rotating part includes gears 6 symmetrically fixed at both ends of the support shaft 402. Spur racks 408 are symmetrically arranged on both sides of the worktable 1 for meshing with the gears 6. The spur racks 408 are fixed to the worktable 1 via connecting brackets 409. The water tank 102 also has symmetrically arranged arc-shaped teeth 101 for meshing with the gears 6 on both sides. It can be noted that after water testing, the cover plate body 7 of this embodiment can be driven by the translation mechanism 2 to continue moving away from the second guide plate 5 along the base 301. When the first guide plate 503 moves in a certain direction, the gear 6 can mesh with the rack 408, and then drive the support shaft 402 to rotate through the gear 6, so as to adjust the sealing plate 4 to cover the water inlet 309 to achieve a seal. As the adjusting motor 505 drives the adjusting frame 504 to rotate, when the water inlet 309 is about to rotate to the point where the opening is completely downward, the arc-shaped tooth 101 meshes with the gear 6 and drives the support shaft 402 to rotate in the opposite direction, so as to open the water inlet 309, so that the test water can be discharged from the water inlet 309 into the water storage tank 102.

[0034] Furthermore, in this embodiment, when the regulating motor 505 drives the water inlet 309 to deflect downward, in order to prevent the pressure plate 305 from separating from the top plate 308 and causing water leakage, the end of the second guide plate 5 away from the first guide plate 503 is also fixedly provided with an arc-shaped frame 502 for rolling contact with the guide wheel 507. It can be explained that as the regulating motor 505 drives the regulating frame 504 to rotate, the guide wheel 507 also rolls and contacts the arc-shaped frame 502, thereby preventing the lifting rod 303 from resetting. The pressure plate 305 can always maintain the effect of pressing the cover plate body 7, the through groove 312, and the sealing ring in the positioning groove 3 tightly against each other. Correspondingly, after the drainage is completed, as the regulating motor 505 drives the regulating frame 504 to rotate in the opposite direction, each component resets accordingly.

[0035] As a further embodiment, when gear 6 is not engaged with the spur rack 408 or the arc-shaped tooth 101, to prevent the sealing plate 4 from rotating, please refer to... Figure 2 L-shaped baffles 404 are fixedly arranged at both ends of the top plate 308. Screws 407 are spirally arranged in the L-shaped baffles 404. The side of the two screws 407 that are close to each other is fixedly connected to the sleeve 406. Key shafts 405 are fixedly arranged at the opposite ends of the two gears 6. The sleeve 406 has a keyway that slides and engages with the key teeth on the key shaft 405. It can be noted that when the support shaft 402 rotates in this embodiment, it can synchronously drive the key shaft 405 to rotate. The key shaft 405 synchronously drives the screws 407 to spirally rotate in the L-shaped baffles 404 through the sleeve 406. Since the screws 407 are spirally connected to the L-shaped baffles 404, the rotation of the screws 407 requires a certain torsional force. Therefore, when the gears 6 are not meshed with the rack 408 or the arc teeth 101, the gears 6 themselves will not rotate, and thus will not drive the sealing plate 4 to rotate, resulting in higher stability.

[0036] A testing method for a testing device using a quick-clamping fixture for water testing of a cover plate includes the following steps: Please refer to Figures 1-5 S1, The loading robot transfers the cover plate body 7 into the positioning groove 3 on the water inspection support 306; S2. The lifting mechanism drives the pressure plate 305 to rise, so that the through groove 312 can cover the cover plate body 7. S3. Pressurize the positioning groove 3 of the water inspection support 306 by supplying air; S4. Add water into the channel 312 through the water inlet 309. Observe the positive and negative terminals, explosion-proof valve and liquid injection hole of the cover plate body 7 to check whether air bubbles are generated, so as to determine whether there is any leakage in the various parts of the cover plate body 7. If no air bubbles are generated, it means that the cover plate body 7 has no leakage.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
