Description

Technical Field

[0001] This utility model relates to an automated testing device for the sealing performance of electric vehicle lamps, belonging to the field of lamp sealing testing technology. Background Technology

[0002] In the production process of electric vehicle lighting components, it is necessary to conduct airtightness tests on the finished parts to determine whether they are qualified. Therefore, there are certain requirements for sealing the parts and sealing them without damaging them. Currently, many testing equipment cannot meet these requirements.

[0003] Existing patent application CN202121018580.9 discloses an airtightness testing device, including a mounting plate, a base plate movably mounted on the mounting plate, a positioning plate for positioning parts on the base plate, a positioning pin and a bottom sealing plate on the positioning plate, the bottom sealing plate being mounted to the positioning plate via the positioning pin, a sealing groove adapted to the shape of the part being formed on the bottom sealing plate, an air inlet and an airtightness testing hole being provided on the bottom sealing plate, a top sealing plate being provided above the bottom sealing plate, a sealing block adapted to the shape of the part being provided on the top sealing plate, and a filler block being provided on the sealing block. This application has a simple structure and can test different models and types of parts by replacing different bottom and top sealing plates, achieving high testing accuracy and minimizing damage to the parts.

[0004] The aforementioned airtightness testing device has the following drawback: it cannot mark products that pass the test, and it is easy to forget whether the tested component is airtight during the subsequent classification process. To address this, we have designed an automated testing device for the sealing performance of electric vehicle lights. Summary of the Invention

[0005] The purpose of this invention is to provide an automated testing device for the sealing performance of electric vehicle lights, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated testing device for the sealing performance of electric vehicle lamps, comprising a testing frame, an outer frame enclosure, and an electric cylinder. A lamp testing platform is fixedly mounted on the top of the testing frame. The outer frame enclosure is bolted to the top of the lamp testing platform and connected to the testing frame. The middle of the top of the outer frame enclosure is fixedly connected to the electric cylinder via a support. The output shaft of the electric cylinder passes through the outer frame enclosure and is connected to a pressure plate. Multiple air inlet valve seats are mounted on the top of the pressure plate. Each air inlet valve seat has an inflation rod passing through the pressure plate at its bottom. Each inflation rod has an inflation plug at its bottom. Each inflation plug has an air outlet at its bottom. A laser marking machine track is provided at the crossbeam at the bottom inner side of the outer frame enclosure. A laser marking head is slidably connected to the laser marking machine track via a slider.

[0007] The aforementioned automated testing device for the sealing performance of electric vehicle lights also includes a valve port sealing component. This component comprises an air source, dual air supply lines, and two inflation rings. The air source is connected to the inlet end of the dual air supply lines, and the two outlet ends of the dual air supply lines are connected to the two inflation rings. The two inflation rings are respectively attached to the outer surface of the inflation plug. This arrangement aims to further align the inflation plug with the light's air inlet channel, resulting in a smaller gap after connection, facilitating better inflation and pressure maintenance, and ensuring that no air leakage occurs at the air inlet end during testing.

[0008] In the aforementioned automated testing device for the sealing performance of electric vehicle lamps, a lamp fixture is installed on the top of the lamp testing platform. The fixture includes a fixture platform mounted on the top of the testing platform. Cylinder components are embedded on both sides of the top of the fixture platform. Linkage rods are installed at the output shafts of both cylinder components, and lamp pressure plates are installed at one end of each linkage rod. Flip hinge rods are installed on the housings of both cylinder components, with each flip hinge rod corresponding to a lamp pressure plate. This design allows for better clamping and limiting of the lamps under test, ensuring good stability during both pressure holding and stamping stages.

[0009] In the aforementioned automated testing device for the sealing performance of electric vehicle lights, a computer casing is installed at the bottom of the front of the outer frame enclosure. A touch-screen computer is embedded in the computer recess of the computer casing, and an alarm light electrically connected to the touch-screen computer is installed at the top of the outer frame enclosure. This design aims to achieve automated control operation and improve testing efficiency.

[0010] In the aforementioned automated testing device for the sealing performance of electric vehicle lights, guide rods are installed at the four corners of the top of the testing platform. Each guide rod is connected to the pressure plate via a guide sleeve. This design ensures good motion accuracy of the pressure plate during its up-and-down movement, reducing instability that could lead to a decrease in the accuracy of the inflation plug connection.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This automated testing device for the sealing performance of electric vehicle lamps, by setting a laser marking machine track at the bottom crossbeam inside the outer frame enclosure, and connecting the laser marking head to the track via a slider, facilitates marking of qualified lamp products, improving subsequent identification and resolution. Furthermore, by including an air source, dual air supply lines, and two inflation rings in the valve sealing component, the inflation plug and the lamp's air inlet channel can be further aligned, resulting in a smaller gap after connection. This facilitates better inflation and pressure maintenance, ensuring no air leakage occurs at the air inlet during testing. Attached Figure Description
