Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a testing equipment for the waterproof performance of mobile phone cameras. Background Technology

[0002] With the rapid development of smartphone technology, users have increasingly higher requirements for the shooting performance of mobile phone cameras and the overall protection level of mobile phones. Among them, the waterproof performance of cameras has become one of the important indicators for measuring product quality. In order to ensure that every camera module leaving the factory can meet the waterproof standards, strict airtightness or waterproofness tests must be carried out using professional testing equipment during the production process.

[0003] However, existing waterproof testing equipment for mobile phone cameras has certain limitations in practical use. Traditional testing methods rely on manual placement of tiny camera modules into the testing fixture. This manual operation is not only labor-intensive and inefficient, but also, due to the randomness of manual operation, it is difficult to ensure that the placement position is precisely aligned with the testing probe each time. This can easily lead to poor sealing or test data errors due to positioning deviations. At the same time, existing testing devices only use a single-direction vertical compression method when constructing the sealed cavity. When high-pressure testing media is introduced, the single-direction vertical pressure cannot completely counteract the internal expansion force, causing slight loosening or lateral leakage in the sealing structure, which in turn affects the accuracy of the test results.

[0004] Therefore, this utility model proposes a mobile phone camera waterproof performance testing device to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in existing mobile phone camera waterproof performance testing equipment, such as low detection positioning accuracy and low operation efficiency due to manual feeding, and inaccurate test results due to lateral leakage caused by the existing sealing structure relying solely on vertical pressure for clamping, this utility model aims to provide a mobile phone camera waterproof performance testing equipment with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a mobile phone camera waterproof performance testing device, including a workbench, a testing mechanism fixedly connected to the middle of the top wall of the workbench, and a pushing mechanism fixedly connected to the top of the outer wall of the workbench.

The fixed frame 1 is fixedly connected to the top of the outer wall of the workbench. The movable frame is driven to move up and down by the hydraulic push rod. The sealing cover cooperates with the positioning plate 1 fixedly installed on the top of the workbench. The pushing mechanism includes a fixed frame 2, a limiting plate fixedly connected to the rear side of the outer wall of the fixed frame 2, a telescopic frame slidably connected inside the limiting plate, an electric push rod rotatably connected to the middle of the telescopic frame, and a positioning plate 1 rotatably connected to the front side of the top of the telescopic frame. The fixed frame 2 is fixedly connected to the rear side of the top of the workbench. The telescopic frame is rotatably connected to the output end of the electric push rod in the middle. The positioning plate 1 of the pushing mechanism is located on the front side of the top of the telescopic frame.

[0008] Preferably, the positioning plate two of the pushing mechanism is slidably connected to the left and right sides of its bottom, and the slide bars are slidably engaged with the top of the worktable. The positioning plate two of the pushing mechanism is slidably connected to the worktable through the slide bars.

[0009] Preferably, a conveying pipe is installed on the side of the movable frame, the conveying pipe passes through the movable frame and communicates with the inside of the sealing cover, and the conveying pipe is used to convey the medium into the inside of the sealing cover.

[0010] Preferably, a detector is fixedly installed on the front and rear sides of the sealing cover, and the detector probe extends into the interior of the sealing cover.

[0011] Preferably, the testing mechanism also includes a cylinder and a fixing plate. The cylinder is fixedly installed on the top wall of the workbench and is located on the side of the sealing cover. The cylinder output end is fixedly connected to the fixing plate, which is located on the side of the sealing cover. The cylinder drives the fixing plate to abut against the outer wall of the sealing cover.

[0012] Preferably, the electric actuator is fixedly installed on the top of the worktable, and the electric actuator is located in front of the second fixing frame.

[0013] Preferably, the positioning plate 2 of the pushing mechanism and the positioning plate 1 of the detection mechanism are positioned corresponding to each other and abutting each other when the pushing mechanism is in the extended state, and the sealing cover vertically projects to cover the positioning plate 1 of the detection mechanism.

[0014] This utility model has the following beneficial effects: 1. This utility model, by setting up a pushing mechanism, uses an electric push rod to push the telescopic frame to drive the positioning plate along the slide bar for automatic feeding, which solves the problems of large positioning deviation and low operation efficiency in the existing technology of manual feeding. It achieves the effect of accurate positioning and automatic conveying of mobile phone camera modules, greatly improving equipment detection efficiency and reducing manual labor intensity.

[0015] 2. This utility model solves the problem of lateral leakage that easily occurs when the sealing cover is sealed by simply relying on vertical pressure for sealing in the existing technology, which is prone to occur when the test pressure is high. It achieves the effect of enhancing the structural stability of the sealing cavity and ensuring the real and accurate data feedback under high pressure test environment. Attached Figure Description
