DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will be further described in detail with the help of the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0024] The specific implementation of the utility model will be described in detail in combination with specific examples.

[0025] As Figure 1 and Figure 2 shown, the utility model embodiment provides a kind of multifunctional battery air tightness detection device, including detection pool 1, and the inside of detection pool 1 is provided with detection table 2, the side of detection table 2 is provided with clamping assembly 3, and clamping assembly 3 is used to be positioned stably with the battery to be measured placed on detection table 2.

[0026] Clamping assembly 3 includes: the both sides of detection table 2 are connected with side plate 301, and the side of side plate 301 is equipped with first telescopic piece 302, and one end of first telescopic piece 302 is provided with clamping rod 303. Clamping rod 303 can be electric telescopic rod or hydraulic telescopic rod.

[0027] In an embodiment of the utility model, the number of detection table 2 is preferably two, and two detection tables 2 are arranged side by side in the inside of detection pool 1. When the air tightness of battery needs to be detected, first, the battery to be measured is placed in the center of the surface of detection table 2, to ensure its stable positioning. Then, start two first telescopic pieces 302, and two first telescopic pieces 302 drive respective clamping rods 303 to move towards the battery to be measured, until two clamping rods 303 simultaneously abut on the surface of the battery to be measured, to further stably position the battery to be measured on the surface of detection table 2, to prevent it from moving or deviating during detection.

[0028] Then, the inside of the battery to be measured is injected with gas by using external gas injection equipment, and whether bubble phenomenon appears in the inside of detection pool 1 is observed, if not, it proves that the air tightness of the battery to be measured is good.

[0029] By the above technical scheme, stable clamping of the measured battery is realized, and in the detection process, the two clamping rods 303 are tightly attached to the surface of the battery, so that the battery is firmly positioned on the detection table 2, and displacement of the battery due to water flow or external interference is effectively prevented. In this way, not only the position accuracy of the battery in the entire air tightness detection is ensured, but also the detection result error caused by the position deviation of the battery is avoided. At the same time, the clamping mechanism makes the entire detection process more safe and reliable, improves the operation efficiency, and ensures the accuracy and consistency of the air tightness detection result.

[0030] In the embodiment, the clamping rod 303 is in L-shaped structure, and the surface of the clamping rod 303 is provided with anti-skid lines. The advantage of this design is that the L-shaped structure can provide a larger contact area, so that the clamping rod 303 can more stably contact and position the measured battery, thereby effectively preventing the battery from tilting or displacing during the detection process. At the same time, the anti-skid lines on the surface of the clamping rod 303 can enhance the friction, further improve the stability of clamping, and avoid the battery from sliding due to unstable clamping.

[0031] By increasing the contact area and the anti-skid performance, not only the fixing reliability of the battery in the detection process is improved, but also the detection error caused by unstable clamping is reduced. In addition, such a structure can adapt to different types and sizes of batteries, improve the universality and practicality of the device, and help to ensure the accuracy and consistency of the detection result.

[0032] In the embodiment, the side of the detection pool 1 is provided with an opening, and the observation window 6 is installed in the opening. The surface of the observation window 6 is provided with a plurality of lower supporting plates 7. By providing the observation window 6 on the side of the detection pool 1, the operator can clearly observe the generation of bubbles in the detection process in real time, which is convenient for judging the air tightness of the battery. In addition, the surface of the observation window 6 is provided with a plurality of lower supporting plates 7, which not only can increase the stability of the observation window, but also can provide lower support for the transparent plate, so as to ensure that it remains stable during operation.

[0033] The setting of the observation window 6 greatly improves the convenience of the detection operation, reduces the detection error, and avoids the missed detection that may be caused by the inability to observe the internal detection process. The supporting effect of the lower supporting plate 7 enhances the service life and safety of the observation window 6, and guarantees the stability of the device during long-term use, thereby further improving the reliability and accuracy of the air tightness detection.

[0034] As shown in Figure 1 and Figure 2 In one embodiment of the utility model, the clamping assembly 3 further comprises: the surface of the side plate 301 is provided with an installation plate 304, and the number of installation plates 304 is preferably two. The side of the installation plate 304 is connected with a rotating frame 305, and the surface of the rotating frame 305 is provided with an air inlet.

[0035] The surface of the rotating frame 305 is provided with a plurality of air blow nozzles 306, the opening direction of the air blow nozzles 306 is downward, that is, corresponding to the position of the battery to be detected. The inside of the rotating frame 305 is provided with a ventilation cavity, and the air blow nozzles 306 are communicated with the ventilation cavity.

[0036] The side of the detection tank 1 is provided with an air pump 4, and one end of the air pump 4 is provided with a gas conveying hose, and the end of the gas conveying hose away from the air pump 4 is communicated with the air inlet.

[0037] In an embodiment of the utility model, when the battery to be detected in the inside of detection tank 1 completes the air tightness detection, and the liquid in the inside of detection tank 1 is fully discharged, although the liquid has been discharged, still a lot of liquid will remain on the surface of the battery to be detected. In order to keep the dryness of the surface of the battery, the traditional way is usually through artificial wiping, however, this method not only consumes time and effort, and the degree of automation is low, and influences the detection efficiency.

[0038] For this technical problem, an automatic liquid cleaning scheme is provided in the application. When the liquid in the inside of detection tank 1 is fully discharged, the air pump 4 can be started, the air pump 4 starts to work, and gas is injected into the ventilation cavity of the rotating frame 305 through the gas conveying hose. The gas is blown out through a plurality of air blow nozzles 306 communicated with the ventilation cavity, and directly acts on the surface of the battery to be detected. Through the air blow nozzles 306, the gas blows the residual liquid on the surface of the battery with uniform pressure, so as to automatically clean the liquid on the surface of the battery.

[0039] Through the above technical scheme, not only the traditional artificial wiping operation is avoided, the working efficiency is improved, but also the operation time is significantly reduced through the automatic blow-drying mode, and the automation level of the whole detection process is improved. At the same time, the uniformly distributed air blow nozzles 306 ensure that the gas can fully cover the surface of the battery, effectively prevent the liquid from remaining, further ensure the cleaning and dryness of the battery, and thus provide a good basis for the subsequent process.

[0040] In the embodiment, the side of the mounting plate 304 is provided with a driving motor, and the output end of the driving motor is connected with the surface of the rotating frame 305.

[0041] The advantage of such design is that the driving motor can directly drive the rotating frame 305 to swing left and right, so that the air blow nozzles 306 can cover multiple angles of the surface of the battery, and realize uniform and efficient blow-drying effect. Through the precise control of the motor, the rotating frame 305 can flexibly adjust the speed and range of swinging, ensure that the airflow can fully cover the surface of the battery, and avoid the unevenness of artificial operation.

[0042] Meanwhile, the drive motor is directly connected to the rotating frame 305, simplifying the overall structural design, reducing the complexity of the intermediate transmission mechanism, and lowering the equipment failure rate. Furthermore, the automated drying process not only improves testing efficiency but also reduces the time and effort required for manual operation, significantly enhancing the automation level and efficiency of the entire airtightness testing process.

[0043] In this embodiment, a movable transparent plate 10 is provided on the surface of the observation window 6, and a handle 11 is installed on the surface of the movable transparent plate 10. A limit frame 8 is provided on the surface of the observation window 6, and the number of limit frames 8 is preferably set to two. A threaded hole is opened on the surface of the limit frame 8, and a bolt rod 9 is engaged inside the threaded hole.

[0044] This effectively prevents liquid from spreading during the air blowing process. The movable transparent plate 10, together with the limiting bracket 8 and the bolt rod 9, ensures that the transparent plate stably blocks the liquid during air blowing, preventing the liquid from splashing everywhere due to the airflow. In addition, the flexible design of the movable transparent plate allows it to be adjusted in position as needed, while the bolt rod 9 can firmly lock it in the ideal position, thus providing a reliable barrier during air blowing, preventing liquid from spreading to other areas, and maintaining a clean and safe testing environment.

[0045] like Figure 1 As shown, in one embodiment of the present invention, the surfaces of the detection pool 1 and the detection stage 2 are jointly provided with an adjustment component 5, and the adjustment component 5 is used to drive the detection stage 2 to move up and down inside the detection pool 1.

[0046] The adjustment component 5 includes: a support frame 503 is provided on the surface of the detection pool 1, and a second telescopic member 502 is mounted on the surface of the support frame 503. Preferably, there are two second telescopic members 502. The second telescopic member can be an electric telescopic rod or a hydraulic telescopic rod.

[0047] One end of the second telescopic member 502 is connected to the connecting plate 501, and the side of the connecting plate 501 is connected to the side of the testing table 2.

[0048] After the battery under test has been tested, the second telescopic component 502 can be opened. One end of the second telescopic component 502 drives the connecting plate 501 to move, and the connecting plate 501 lifts the test stage 2 and the battery under test on the test stage 2, thereby detaching the battery under test from the liquid being tested. This technical solution eliminates the need for manual removal of the battery under test from the liquid, avoiding the tediousness and possibility of misoperation caused by manual operation, reducing the risk of personnel contact with the liquid, and improving the convenience and safety of operation.

[0049] In addition, the residual liquid on the surface of the battery under test can be blown and cleaned by the air pump 4 and the blowing nozzle 306 without completely discharging the liquid inside the detection pool 1. In this way, not only the time is saved, the process of frequent discharging and re-injection of the liquid is avoided, but also the cleaning step can be efficiently completed, the continuity and the automation level of the detection process are ensured, and thus the overall detection efficiency and the cleaning effect are improved.

[0050] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
