Description

Technical Field

[0001] This utility model relates to the field of airtightness testing fixtures, specifically a fixture for testing the airtightness of an automotive battery cover. Background Technology

[0002] In the automotive manufacturing industry, the airtightness of the battery cover is one of the key factors in ensuring battery safety and reliability. Poor airtightness of the battery cover may lead to gas leakage inside the battery, which not only affects the battery's performance and lifespan, but may also cause safety problems such as battery short circuits and fires. Therefore, accurate airtightness testing of automotive battery covers is an indispensable part of the production process.

[0003] The limitations of traditional testing methods are that manual testing relies on the experience and skills of operators, is slow, and cannot meet the needs of large-scale production. The accuracy of manual testing is greatly affected by the subjective judgment of operators, which can easily lead to misjudgments. Long-term repetitive operation can easily lead to operator fatigue, further reducing the accuracy and efficiency of testing. Simple mechanical testing devices, although some simple mechanical testing devices can improve testing efficiency, have limited functions. These devices can usually only perform a single testing operation and cannot achieve automation and classification processing. Subsequent processing steps still require manual intervention. Therefore, a tooling for testing the airtightness of automotive battery covers is proposed. Utility Model Content

The moving module 301 is fixed to the top wall of the inner cavity of the frame 2, and the cylinder 302 is fixed to the moving module 301.

[0020] Specifically, the connecting plate 303 is fixed to the outside of the piston rod of the cylinder 302, the four spring telescopic rods 304 are all fixed at the four corners of the lower surface of the connecting plate 303, the fixing plate 305 is fixed to the lower surface of the four spring telescopic rods 304, the four suction cups 306 are all fixed at the four corners of the lower surface of the fixing plate 305, the two frames 307 are all fixed to the upper surface of the support platform 5, the two pressure sensors 308 are all fixed to the left and right side walls of the inner cavity of the right frame 307, the air pump 309 is fixed to the base 1, the upper surface of the right frame 307 is fixed with a rubber sealing ring, the right frame 307 is compatible with the battery cover, and the battery cover can cover the upper surface of the right frame 307 to form a seal.

[0021] Specifically, the connector includes a vacuum pump 310 fixed on the connecting plate 303. The vacuum pump 310 is fixedly connected to the back of the right rear suction cup 306 through a movable tube. The four suction cups 306 are all connected to each other through pipes. The output end of the air pump 309 is fixedly connected to the back of the right frame 307 through a connecting pipe. An electromagnetic valve is provided on the connecting pipe.

[0022] Specifically, multiple car battery covers are placed inside the left frame 307. Then, the equipment is started via the control panel 8. The moving module 301 moves the fixing plate 305 and four suction cups 306 to the left and to the upper side of the left frame 307. Then, the cylinder 302 is activated, moving the suction cups 306 downward to contact the uppermost car battery cover. After that, the vacuum pump 310 is activated, and the four suction cups 306 suck up the uppermost car battery cover. This reduces manual intervention and improves inspection efficiency. Based on the airtightness results, the battery covers are sorted and transferred to different conveyor belt mechanisms 4 for subsequent processing and classification, thus improving production efficiency.

[0023] Specifically, the spring telescopic rod 304 includes a first slide rod, a second slide rod is slidably connected inside the first slide rod, a spring is movably fitted on the outside of the first slide rod, a rubber frame is fixed inside the left frame 307, and openings are provided through the support platform 5, the left frame 307, and the lower surface of the rubber frame. An electric push rod 6 is fixed to the top wall of the inner cavity of the support platform 5 by a mounting bracket. A movable plate 7 is slidably connected inside the rubber frame. By activating the electric push rod 6, the movable plate 7 can be moved up and down inside the rubber frame to push out the battery cover inside the rubber frame. The rubber frame is compatible with the battery cover, and the battery cover can move up and down inside the rubber frame. The outer side of the output shaft of the electric push rod 6 passes through the opening and is fixedly connected to the lower surface of the movable plate 7.

[0024] It should be noted that both cylinder 302 and moving module 301 are activated, moving the car battery cover to the right frame 307 and pressing it against the rubber sealing ring to form a seal. Then, air pump 309 is activated to inflate the inside of the right frame 307. After that, the solenoid valve controls the airflow. Then, pressure sensor 308 inside the right frame 307 monitors the air pressure changes in real time. Control panel 8 judges the airtightness of the battery cover based on the data from pressure sensor 308. If the air pressure drops beyond the set threshold, control panel 8 will issue an alarm indicating that the battery cover is not airtight. After the test is completed, under the joint action of cylinder 302 and moving module 301, the battery cover with unqualified airtightness can be moved to the rear conveyor belt mechanism 4, and the battery cover with qualified airtightness can be moved to the front conveyor belt mechanism 4.

[0025] It should be noted that all electrical components appearing in this embodiment are electrically connected to the control panel 8 and the power supply. The control panel 8 can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing publicly available power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.

[0026] The working principle of the above embodiments is as follows: In use, multiple car battery covers are placed inside the left frame 307. Then, the device is started via the control panel 8. The moving module 301 moves the fixing plate 305 and four suction cups 306 to the left, moving them to the upper side of the left frame 307. Then, the cylinder 302 is activated, moving the suction cups 306 downwards to contact the uppermost car battery cover. Next, the vacuum pump 310 is activated, and the four suction cups 306 hold the uppermost car battery cover in place. Then, both the cylinder 302 and the moving module 301 are activated, moving the car battery cover to the upper right frame 307 and pressing it against the rubber sealing ring to form a seal. Finally, the air pump 309... Upon startup, the right-side frame 307 is inflated. Then, the solenoid valve controls the airflow. The pressure sensor 308 inside the right-side frame 307 monitors the air pressure changes in real time. The control panel 8 determines the airtightness of the battery cover based on the data from the pressure sensor 308. If the air pressure drops beyond the set threshold, the control panel 8 will issue an alarm indicating that the battery cover is not airtight. After the test is completed, the battery cover with unqualified airtightness can be moved to the rear conveyor belt mechanism 4 through the combined action of the cylinder 302 and the moving module 301, while the battery cover with qualified airtightness can be moved to the front conveyor belt mechanism 4.
