Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery cover plate detection, and in particular relates to a rapid pressing tool for cover plate water detection and a detection device thereof. BACKGROUND

[0002] In the field of new energy battery manufacturing, the sealing performance of the battery cover plate is one of the key factors determining the safety and service life of the battery. Air tightness detection, or leak detection, is an essential inspection link in the production process. Currently, in addition to using high-precision helium mass spectrometer leak detectors, water detection method is widely used due to its intuitive and low cost.

[0003] In the prior art, a water detection tool for new energy battery cover plates is disclosed in the utility model patent with publication number CN219455400U. The tool generally includes a base, guide columns, a positioning plate, and a sliding block. The sliding block is provided with a groove for placing the cover plate, and the sliding block and the positioning plate are pressed together by a gas cylinder drive, so that each component (such as the positive and negative poles, the explosion-proof valve, and the liquid injection hole) on the cover plate is aligned with the corresponding openings on the positioning plate. During detection, the operator drops water at these openings, and then fills a certain pressure of gas into the sealed cavity formed by the cover plate and the sliding block, and judges the sealing performance of the corresponding position by observing whether bubbles are generated in the water.

[0004] However, the existing tool has a significant defect: after detection is completed, the water accumulated on the surface of the positioning plate, especially in the recessed openings such as the liquid injection hole, cannot be effectively drained. If the gas cylinder is directly driven to separate the sliding block and the positioning plate at this time, the residual accumulated water will flow freely due to the loss of restraint. This not only makes the equipment and workbench wet, causing inconvenience to cleaning and affecting work efficiency; more seriously, the water flow may seep into the internal parts of the pneumatic elements or guide mechanisms of the tool, causing equipment rusting, damage or electrical short circuit, shortening the service life of the equipment, and posing a safety hazard.

Specifically, the guide rod 302 of the present embodiment is provided with four groups and is symmetrically arranged at both ends of the base 301.

[0022] In the embodiment, a pressing plate 305 is further arranged between the base 301 and the top plate 308, the pressing plate 305 is sleeved on each guide rod 302, wherein the pressing tool further comprises a lifting mechanism, the lifting mechanism is used to drive the pressing plate 305 to slide on the guide rod 302; Specifically, the pressing plate 305 and the top plate 308 of the embodiment are provided with a water detection tool for sealing detection of the cover plate body 7; It can be explained that when the cover plate body 7 is water detected, the pressing plate 305 is first driven to descend by the lifting mechanism and separated from the top plate 308, secondly, the cover plate body 7 to be detected is placed at the water detection tool, and then the pressing plate 305 is driven to rise by the lifting mechanism, so that the force is directly and uniformly applied on the water detection tool, thereby the cover plate body 7 and the sealing ring in the entire water detection tool are pressed at one time, the side edge of the cover plate body 7 is sealed by the sealing ring, so that the subsequent inflation water detection is avoided to avoid the gas leakage from the side edge of the cover plate body 7 or the water entering the water detection tool from the side edge of the cover plate body 7, so as to ensure the quality of the subsequent water detection.

[0023] As an embodiment of the embodiment, the water detection tool comprises a water detection support 306 fixed on the pressing plate 305, the water detection support 306 is provided with a positioning groove 3 for embedding the cover plate body 7, wherein the water detection tool further comprises a water detection sealing seat 307 fixed on the bottom of the top plate 308, the water detection sealing seat 307 is provided with a through groove 312 corresponding to the positioning groove 3, wherein the top plate 308 is provided with a water inlet 309 communicating with the through groove 312; It can be explained that when the cover plate body 7 is water detected, the cover plate body 7 is transferred to the positioning groove 3 on the water detection support 306 by the feeding mechanical arm, the cover plate body 7 is positioned by the positioning groove 3 to ensure the stability of the subsequent water detection, and then the pressing plate 305 is driven to rise by the lifting mechanism, so that the through groove 312 can be covered on the cover plate body 7, at the same time, the positioning groove 3 and the through groove 312 can be provided with a sealing ring, the cover plate body 7 and the sealing ring in the through groove 312 and the positioning groove 3 are pressed by the pressure of the pressing plate 305, thereby the sealing property of the side edge of the cover plate body 7 is ensured, at this time, the positive and negative poles, the explosion-proof valve and the liquid injection hole on the cover plate body 7 are located in the through groove 312, when the gas is input into the positioning groove 3 of the water detection support 306, the water is added into the through groove 312 from the water inlet 309, and then the positive and negative poles, the explosion-proof valve and the liquid injection hole of the cover plate body 7 are observed to detect whether the bubbles are generated, thereby judging whether the leakage phenomenon occurs at each part on the cover plate body 7, if no bubbles are generated, it indicates that the cover plate body 7 has no leakage.

[0024] In the embodiment, the lifting mechanism includes a lifting cylinder fixed on the base 301, and the driving end of the lifting cylinder is fixed with the pressing plate 305. It can be explained that when the pressing plate 305 is driven to lift, the lifting cylinder can be started to drive the pressing plate 305 to slide on the guide rod 302. Correspondingly, the lifting cylinder of the embodiment can also be replaced by an electric cylinder or a hydraulic cylinder to meet the actual application requirements. The specific type and structure of the embodiment are not limited.

[0025] Embodiment 2

[0026] Based on the embodiment 1, please refer to Figures 1-2 and Figures 4-5 A detection device for cover plate water detection further includes a workbench 1, and the lifting mechanism includes a lifting rod 303 fixed on the bottom of the pressing plate 305. The lifting rod 303 is provided with a telescopic spring 304. One end of the telescopic spring 304 is fixed with the base 301, and the other end is fixed with the lifting rod 303. The end of the lifting rod 303 away from the pressing plate 305 is slidably penetrated through the base 301. The bottom end of the lifting rod 303 is rotatably arranged with a guide wheel 507. The workbench 1 is fixedly arranged with a first guide plate 503 parallel to the workbench 1. The position of the first guide plate 503 corresponds to the guide wheel 507. The end of the first guide plate 503 is fixedly arranged with an inclined guide plate 501. The inclined guide plate 501 is inclined away from the workbench 1. The other end of the inclined guide plate 501 is fixedly arranged with a second guide plate 5, which is arranged parallel to the workbench 1. The lifting mechanism further includes a translation mechanism 2, which is used to drive the base 301 to reciprocate on the workbench 1. It can be explained that in the initial state, the base 301 is driven by the translation mechanism 2 to move above the first guide plate 503, and the guide wheel 507 is supported by the first guide plate 503. At this time, the distance between the pressing plate 305 and the top plate 308 is the largest, which facilitates the mechanical hand to load the cover plate body 7 to be water detected into the positioning groove 3. After the loading is completed, the base 301 is driven by the translation mechanism 2 to move towards the second guide plate 5. Based on the arrangement of the inclined guide plate 501, the lifting rod 303 can be driven to rise by the guide wheel 507. The lifting rod 303 rises synchronously to drive the pressing plate 305 to rise, so as to realize the effect of pressing the cover plate body 7, the through groove 312 and the sealing ring in the positioning groove 3. Correspondingly, when the water detection is completed, the base 301 can be reset by the translation mechanism 2, and the pressing plate 305 can be separated from the top plate 308, so as to facilitate subsequent unloading and new loading. Based on this, the embodiment does not need to set other servo devices to adjust the height of the base 301. With the translation of the base 301, the effect of automatically adjusting the lifting of the pressing plate 305 can be realized, which not only reduces the cost, but also has higher synchronism and stability.

[0027] In addition, the translation mechanism 2 of the embodiment can adopt a synchronous belt transmission mechanism or a screw transmission mechanism, and the present embodiment is not limited thereto, and can meet the actual application requirements.

[0028] As an implementation manner of the embodiment, in order to automatically drain the water in the water inlet 309 and the through groove 312 after the water detection is completed, 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 fixedly provided with adjusting frames 504, one side of the adjusting plate 506 is fixedly provided with an adjusting motor 505, and the driving end of the adjusting motor 505 is fixedly connected with the adjusting frame 504 through the adjusting plate 506. It can be explained that during the water detection, the opening of the water inlet 309 is upward, and after the water detection is completed, the adjusting motor 505 can be used to drive the adjusting frame 504 to rotate by 180 degrees, so that the opening of the water inlet 309 is downward, and then the detection water in the water inlet 309 and the through groove 312 can be automatically drained under the action of gravity, so as to avoid the phenomenon that the detection water flows freely after the detection is completed, and to collect and process the detection water again.

[0029] It should be noted that since the positive and negative pole columns, the explosion-proof valve and the liquid injection hole on the cover plate body 7 are all special-shaped structures, and there are dead angle gaps, it is difficult to use the adsorption method to suck out the detection water in the water inlet 309 and the through groove 312, and the embodiment uses the pouring method, which can effectively pour out all the water and will not be left.

[0030] In addition, it can be seen from Figure 3 that one side of the water detection support 306 is connected with an air inlet pipe 310, and the air inlet pipe 310 is in communication with the positioning groove 3, wherein one side of the workbench 1 is further provided with a gas conveying pipe 311 connected with a gas pump, and the height of the air inlet pipe 310 is flush with that of the gas conveying pipe 311. 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 is in communication with the gas conveying pipe 311, and when the water pump is started, the water can be conveyed into the positioning groove 3 through the gas conveying pipe 311 and the air inlet pipe 310, so as to realize the effect of inflation, and facilitate subsequent leakage detection.

[0031] As an implementation manner of the embodiment, it can be seen from Figures 1-3 and Figures 6-8 that one side of the bottom of the workbench 1 is further provided with a water storage tank 102, which is used for collecting and processing the detection water poured in the water inlet 309 and the through groove 312. Specifically, when the water inlet 309 is rotated to have the opening downward, the detection water in the interior can be drained into the water storage tank 102 under the action of gravity for collection, so as to facilitate subsequent unified processing.

[0032] It should be noted that when the water inlet 309 is not rotated to the downward opening, for example, 90 degrees, in order to avoid the detection of water flowing out in advance and causing the collection to be unable to be collected, in the embodiment, the top plate 308 is further provided with a sealing plate 4 for closing the water inlet 309, both ends of the sealing plate 4 are fixedly arranged with L-shaped supports 401, the other end of the L-shaped support 401 is fixed on the support shaft 402, both ends of the support shaft 402 are fixed on the top plate 308 through the limiting seat 403, wherein the top plate 308 is further provided with a rotating part, the rotating part is used to drive the support shaft 402 to rotate; it can be explained that in the process of detecting the cover plate body 7, the rotating part adjusts the sealing plate 4 and the water inlet 309 to be in a separated state, so as to add detection water to the water inlet 309 and observe whether bubbles are generated, when the detection is completed and the detection water needs to be discharged, the embodiment can first drive the support shaft 402 to rotate through the rotating part, the support shaft 402 drives the sealing plate 4 to rotate synchronously through the L-shaped support 401, so that the sealing plate 4 can be covered on the water inlet 309, to realize the effect of closing the water inlet 309, correspondingly, when the water inlet 309 is about to be rotated to the completely downward opening, the sealing plate 4 is driven to rotate in the direction away from the water inlet 309 through the rotating part in advance, to open the water inlet 309, so as to facilitate the detection water to be discharged.

[0033] Specifically, the rotating part includes gears 6 symmetrically fixed on both ends of the support shaft 402, both sides of the workbench 1 are symmetrically provided with straight racks 408 for engaging with the gears 6, both sides of the straight racks 408 are fixed on the workbench 1 through the connecting frame 409, wherein both sides of the water storage tank 102 are symmetrically provided with arc-shaped teeth 101 for engaging with the gears 6; it can be explained that the cover plate body 7 of the embodiment can drive the base 301 to continue to move away from the first guide plate 503 through the translation mechanism 2 after the water detection is completed, the gears 6 can engage with the straight racks 408, and then the support shaft 402 is driven to rotate through the gears 6, to adjust the sealing plate 4 to cover the water inlet 309 to realize sealing, along with the process that the adjusting motor 505 drives the adjusting frame 504 to rotate, when the water inlet 309 is about to be rotated to the completely downward opening, the arc-shaped teeth 101 engage with the gears 6 to drive the support shaft 402 to rotate reversely, to open the water inlet 309, so that the detection water can be discharged from the water inlet 309 to the water storage tank 102.

[0034] Further, in the embodiment, when the adjusting motor 505 drives the water adding opening 309 to deflect downward, in order to avoid the phenomenon of water leakage caused by the separation of the pressing plate 305 and the top plate 308, the second guide plate 5 is further fixed with an arc-shaped frame 502 for rolling abutment with the guide wheel 507 away from one end of the first guide plate 503; it can be explained that, with the rotation of the adjusting motor 505 driving the adjusting frame 504, the guide wheel 507 also rolls abutment with the arc-shaped frame 502, thereby avoiding the reset of the lifting rod 303, and the pressing plate 305 can always keep the effect of pressing the cover plate body 7 and the sealing ring in the through slot 312 and the positioning groove 3; correspondingly, after the water is drained, with the reverse rotation of the adjusting motor 505 driving the adjusting frame 504, the components are reset.

[0035] As a further scheme of the embodiment, when the gear 6 is not engaged with the straight rack 408 or the arc-shaped tooth 101, in order to avoid the rotation of the sealing plate 4, it can be seen from Figure 2 , both ends of the top plate 308 are fixed with L-shaped blocking frames 404, and the L-shaped blocking frames 404 are spirally arranged with screw rods 407, and one side of the two screw rods 407 close to each other is fixedly connected with the sleeve 406, wherein one end of the two gear 6 away from each other is fixedly arranged with a key shaft 405, and the sleeve 406 is provided with a key groove for sliding and clamping with the key teeth on the key shaft 405; it can be explained that, when the support shaft 402 of the embodiment rotates, the key shaft 405 can be synchronously driven to rotate, and the key shaft 405 synchronously drives the screw rod 407 to rotate in the L-shaped blocking frame 404 through the sleeve 406. Since the screw rod 407 is spirally connected with the L-shaped blocking frame 404, a certain torsional force is required for the rotation of the screw rod 407, so when the gear 6 is not engaged with the straight rack 408 or the arc-shaped tooth 101, the gear 6 itself will not rotate, thereby avoiding driving the sealing plate 4 to rotate, and the stability is higher.

[0036] A detection method of a detection device of a quick pressing tool for cover plate water detection, comprising the following steps: It can be seen from Figures 1-5 S1, the feeding manipulator transfers the cover plate body 7 to the positioning groove 3 on the water detection support 306; S2, the lifting mechanism drives the pressing plate 305 to rise, so that the through slot 312 can be covered on the cover plate body 7; S3, air is input into the positioning groove 3 of the water detection support 306 to pressurize; S4, water is added into the through slot 312 from the water adding opening 309, and the positive and negative electrode columns, the explosion-proof valve and the liquid injection hole of the cover plate body 7 are observed to detect whether bubbles are generated, so as to judge whether there is leakage phenomenon at each part of the cover plate body 7, and if no bubbles are generated, it indicates that the cover plate body 7 has no leakage.

[0037] The above disclosed are only several specific embodiments of the present application, but the embodiments of the present application are not limited thereto, and any changes that can be thought of by any person skilled in the art shall fall into the protection scope of the present application.
