Abstract
Description
Technical Field
[0001] This utility model relates to the field of camera inspection, specifically to a camera airtightness testing fixture. Background Technology
[0002] Cars are a common mode of transportation in people's daily lives, and for automotive products, the in-vehicle camera is undoubtedly a crucial element reflecting their safety performance. During the manufacturing process of in-vehicle cameras, an airtightness test is required. This test typically involves placing the semi-finished product in a sealed cavity fixture, then placing the fixture in a water tank. Gas is then injected into the fixture using an airtightness instrument, and the presence of bubbles escaping from the fixture's vent is observed within the water tank to assess the camera's seal. However, existing sealing fixtures are complex in structure, cumbersome to install, and prone to seal failure, leading to inaccurate test results. Summary of the Invention
[0003] To address the shortcomings of the existing technology, this utility model provides a camera airtightness testing fixture, which has a simple structure, is easy to clamp, and improves testing efficiency.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A camera airtightness testing fixture, characterized in that it includes a base, a lower cavity, and an upper cavity. The lower cavity is disposed on the base, and the upper cavity is snapped onto the lower cavity. The lower cavity has multiple camera placement slots, and the upper cavity has lens sealing slots corresponding to the camera placement slots. A sealing strip is provided between the contact surfaces of the lower and upper cavities. A soft silicone gasket is provided inside the lens sealing slot. A quick-connect air pipe connector communicating with the camera placement slots is provided on the lower cavity. A top block is provided on the top surface of the upper cavity, and a quick clamp for pressing the top block is provided on the base.
[0006] Furthermore, the base is provided with a right quick clamp fixing seat and a left quick clamp fixing seat, and two quick clamps are respectively provided on the right quick clamp fixing seat and the left quick clamp fixing seat.
[0007] Furthermore, the multiple camera placement slots are connected to the quick-connect trachea connector via connecting slots.
[0008] The advantages of this utility model include: it can better fix and limit the product, has a simple structure, is easy to clamp, and can quickly detect whether the airtightness of the camera meets the standard, thus improving the detection efficiency. Attached Figure Description

[0010] Figure 2 This is a top view of the present invention;
[0011] Figure 3 This is a schematic diagram of the lower cavity structure of this utility model;
[0012] Figure 4 This is a schematic diagram of the upper cavity structure of this utility model. Detailed Implementation
[0013] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0014] One such Figure 1-4 The vehicle-mounted camera wiring harness welding fixture shown includes a base 1, a left quick-clamp fixing seat 2, a right quick-clamp fixing seat 3, a quick-clamp 4, a lower cavity 5, a sealing strip 6, an air hose quick connector 7, an upper cavity 8, a soft silicone gasket 9, and a top block 10. The base 1 has a left quick-clamp fixing seat 2 and a right quick-clamp fixing seat 3 on its left and right sides, respectively. Two quick-clamps 4 are each mounted on the left quick-clamp fixing seat 2 and the right quick-clamp fixing seat 3. The lower cavity 5 is fixed to the base 1 with screws and has round-headed pins on its end face. The lower cavity 5 has multiple camera placement slots 51, and an air hose quick connector 7 is located at the rear of the lower cavity 5. The air hose quick connector 7 communicates with the multiple camera placement slots 51 through a connecting groove 52.
[0015] A sealing strip 6 is provided between the contact surfaces of the lower cavity 5 and the upper cavity 8. The upper cavity 8 is provided with a lens sealing groove 81 corresponding to the camera placement groove 51, and a soft silicone gasket 9 is provided at the bottom of the lens sealing groove 81.
[0016] The upper cavity 8 is fixed to the top block 10 by screws, and then positioned and pressed and fixed to the lower cavity 5 by round-headed pins and quick clamps 4.
[0017] The implementation steps and principles of this invention are as follows:
[0018] S1. By manually feeding the product, place it in the lower cavity, use quick clamps and round-headed pins to limit and fix the upper cavity and top block, and connect the quick connector of the air pipe to the air pipe for ventilation. After ventilation, use a cotton swab to apply water-based cleaning agent around the lens surface and check the lens surface phenomenon within 2 seconds. If bubbles are generated, it is considered NG; if no bubbles are generated, it is considered OK.
[0019] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model.
