Description

Technical Field

[0001] The invention relates to the technical field of camera testing, in particular to a high-temperature image output device for a vehicle-mounted camera. Background Art

[0002] Car cameras have become an indispensable part of the automotive industry. In order to adapt to the environment in some parts of the world, car cameras must also bear the challenges of various harsh environments. High-temperature image output equipment is a device developed for high-temperature environments. In midsummer, the temperature inside the car is generally around 50°C, but due to different regions and longitudes and latitudes, the temperature in some areas can reach around 70°C. The existing high-temperature image output equipment is to manually plug and unplug the camera to complete the high-temperature image output, which has the following defects:

[0003] First, when manually plugging and unplugging the camera for high-temperature display, due to manual plugging and unplugging, only one camera can be connected at a time. After a certain number of cameras are connected, all connected cameras can display at high temperature together (the time for high-temperature display is 30 minutes). Therefore, manual plugging and unplugging of the camera is inefficient and not conducive to large-scale production.

[0004] Second, when manually plugging and unplugging the camera for high-temperature display, when defective products appear in the high-temperature display, the position of the camera in the high-temperature box will be more confusing due to manual plugging and unplugging, so it will be more difficult to find the defective products;

[0005] Third, after the high-temperature image is finished, the car camera needs to be unplugged and retracted. At this time, because the camera has been baked at high temperature, the temperature of the camera itself is very high. Manually unplugging and plugging the camera will cause burns, and you will feel very hot even if you wear special gloves. Summary of the invention

[0006] In view of the above problems, the present invention provides a high-temperature image output device for a vehicle-mounted camera, which adopts a mechanical and electronic automatic plug-in and unplugging method, which not only relieves the work pressure of employees, but also greatly improves work efficiency and safety.

[0032] In a specific implementation, the name of the terminal is fakara terminal.

[0033] The workflow is as follows:

[0034] 1 When powered on and ventilated, the high-temperature equipment of the vehicle camera in the figure is in the initial no-load state;

[0035] 2 Push the tray with the vehicle-mounted camera into the device through the two slide blocks of the device. Push the tray to the stop bolt position and stop. At this time, push the elbow clamps on both sides of the device upwards. The guide pins connected to the elbow clamps slide into the guide bushings. Check the status of the elbow clamp side sensor on the display screen to check whether the guide pins are fully positioned to complete the preliminary positioning of the vehicle-mounted camera tray.

[0036] 3. The first lifting cylinders on both sides are controlled to fall down at the same time to drive the front shell pressing plate. At this time, the front shell pressing plate presses the front shell of the vehicle-mounted camera. The second guide pin in the front shell pressing plate is aligned with the positioning bushing of the material tray. At this time, the front shell pressing plate is positioned on the vehicle-mounted camera material tray;

[0037] 4. Control the second lifting cylinder to rise and drive the joint base fixing plate. At this time, the upper convex terminal is connected to the terminal of the vehicle camera to ensure the transmission of the signal. The third guide pin in the joint base fixing plate is aligned with the second alignment bushing of the material tray. At this time, the joint base fixing plate is positioned on the vehicle camera material tray;

[0038] 5 After the above operations are completed, the vehicle-mounted camera can be subjected to a high-temperature test. After the test is completed, first operate the second lifting cylinder to fall to disconnect the upper convex terminal from the vehicle-mounted camera terminal, and then operate the first lifting cylinders on both sides to rise at the same time to separate the front shell pressure plate from the front shell of the vehicle-mounted camera (the vehicle-mounted camera shell material used by our company will not soften and stick in a high-temperature environment), and finally push the elbow clamp to separate the guide pin from the material tray. After that, the operator can take out the material tray through the heat-insulating handle. At this time, the entire equipment returns to its initial no-load state.
