Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a micro-module mounting and calibration device. Background Technology

[0002] A micromodule is a miniature electronic functional component, typically used in applications such as radio frequency, communication, and sensors. It is characterized by high integration, miniaturization, high performance, and multifunctionality. Its installation requires extremely high positioning accuracy to ensure the correct alignment of optical paths or other critical functions.

[0003] In the assembly process of micro-modules, mounting components are typically used to clamp the micro-modules, and then a CDD camera scans and positions the contours of the micro-modules. Finally, the micro-modules are mounted based on the positioning data. However, after long-term operation or equipment maintenance and replacement, the mounting components and the CDD camera themselves may develop certain deviations in their installation and positioning, which in turn affects the accuracy and firmness of the mounting.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a micro-module mounting and calibration device to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and for the convenience of those skilled in the art to understand it. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background of this utility model. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention discloses a micro-module mounting calibration device for calibrating the mounting components and CDD camera of the micro-module, thereby solving the problem that the positioning of the mounting components and CDD camera is prone to deviation after maintenance, replacement or long-term use.

[0007] This utility model discloses a micro-module mounting calibration device, including a mounting base plate, on which a camera calibration component and a mounting axis calibration component are positioned and disposed;

[0008] The camera calibration assembly includes a positioning post fixed to the mounting base plate, with a focusing plate on the top of the positioning post;

[0009] The mounting axis calibration assembly includes a lifting frame fixed to the mounting base plate. A lifting slider is slidably connected to the lifting frame in the vertical direction. A calibration platform is provided on the top of the lifting slider. A mounting positioning groove is provided on the calibration platform. A pressure sensor is provided in the mounting positioning groove. A flexible pad is provided on the test end plane of the pressure sensor. Under normal conditions, the upper end plane of the flexible pad is flush with the upper end plane of the calibration platform. A micrometer is provided on the lifting slider in the vertical direction. The test axis of the micrometer is set in the vertical direction towards the mounting base plate. The lifting distance of the lifting slider is controlled by the extension and retraction of the test axis.

[0010] Preferred technical solution: When the lifting slider slides to the bottom of the lifting frame, the value of the micrometer returns to zero, which facilitates the control of the lifting height of the lifting slider.

[0011] Preferred technical solution: A guide block is slidably connected to the outer periphery of the test shaft. The guide block is slidably connected to the lifting frame in the vertical direction, which improves the stability of the micrometer installation and avoids bending of the test shaft due to long-term use.

[0012] Preferred technical solution: The flexible gasket is made of rubber, which has good durability.

[0013] Preferred technical solution: The pressure sensor is one of a flexible pressure sensor, an optical fiber pressure sensor, and a MEMS pressure sensor, ensuring the response speed and accuracy of pressure measurement.

[0014] Preferred technical solution: The lifting frame and the mounting base are connected by a calibration block, and the front end of the test shaft is abutted against the top end of the calibration block to ensure the measurement accuracy of the micrometer.

[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0016] This invention discloses a micro-module mounting calibration device. A camera calibration component positions and calibrates a CDD camera, ensuring accurate micro-module contour coordinates captured by the CDD camera. A mounting axis calibration component, fixed relative to the camera calibration component, simulates mounting the micro-module assembly. During the simulated mounting process, if the mounting position of the micro-module assembly deviates, it cannot enter the mounting positioning slot, allowing for timely adjustment and preventing the production of products with misaligned micro-modules. Simultaneously, during the simulated mounting process, a micrometer can be used to adjust the mounting height according to different products, and a pressure sensor measures the mounting pressure to ensure it meets standards, guaranteeing the firmness of the micro-module mounting. A flexible gasket on top of the pressure sensor simulates the adhesive used during micro-module mounting, while also preventing damage to the pressure sensor from irregular surfaces on the micro-module.

[0028] Example:

[0029] like Figure 1 As shown, this utility model discloses a micro-module mounting calibration device, including a mounting base plate 100. A camera calibration component 1 and a mounting axis calibration component 2 are positioned on the mounting base plate 100. The main components of this utility model will be described in detail below:

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the camera calibration assembly 1 includes a positioning post 11 fixed on the mounting base plate 100, and a focusing plate 12 is provided on the top of the positioning post 11.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, the mounting axis calibration assembly 2 includes a lifting frame 21 fixed on the mounting base plate 100. A lifting slider 22 is slidably connected to the lifting frame 21 in the vertical direction. A calibration platform 22a is provided on the top of the lifting slider 22. A mounting positioning groove 22b is provided on the calibration platform 22a. A pressure sensor 22c is provided in the mounting positioning groove 22b. A flexible pad 22d is provided on the test end plane of the pressure sensor 22c. The upper end plane of the flexible pad 22d is flush with the upper end plane of the calibration platform 22a under normal conditions. A micrometer 23 is provided on the lifting slider 22 in the vertical direction. The test shaft 23a of the micrometer 23 is set in the vertical direction toward the mounting base plate 100. The lifting slider 22 controls the lifting distance by the extension and retraction of the test shaft 23a.

[0032] The usage method and principle of this utility model are as follows: In use, the CDD camera is moved above the camera calibration component 1 and positioned and calibrated by the focusing plate 12. After calibration, the micro-module is picked up by the mounting component, and the calibrated CDD camera is used to take pictures and position the micro-module. According to the positioning information, the mounting component is controlled to move above the mounting axis calibration component 2 for simulated mounting. During the simulated mounting process, if the mounting position of the micro-module mounting component deviates, it cannot enter the mounting positioning groove 22b, and can be adjusted in time to avoid producing products with misaligned micro-module mounting. During the simulated mounting process, the height of the lifting slider 22 is adjusted by the micrometer 23 according to different products, and the mounting pressure is measured by the pressure sensor 22c to ensure that the mounting pressure meets the standard, avoiding incomplete mounting or excessive mounting force, and ensuring the firmness of the micro-module mounting. A flexible pad 22d is set on the top of the pressure sensor 22c to simulate the glue used when mounting the micro-module, avoiding damage to the pressure sensor 22c caused by irregular surfaces on the micro-module.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, in order to facilitate the adjustment of the height of the lifting slider, when the lifting slider 22 is at the bottom of the lifting frame 21, the value of the micrometer 23 is zero, which makes it easy to read the displacement height of the lifting slider 22.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, in order to ensure the displacement accuracy of the lifting slider, a guide block 24 is slidably connected to the outer periphery of the test shaft 23a. The guide block 24 is slidably connected to the lifting frame 21 in the vertical direction to avoid bending of the test shaft 23a due to long-term use.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, to increase the service life of the flexible gasket, the flexible gasket 22d is made of rubber.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, to ensure the corresponding speed and accuracy of pressure measurement, the pressure sensor 22c is one of a flexible pressure sensor, an optical fiber pressure sensor, and a MEMS pressure sensor.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, to ensure the measurement accuracy of the micrometer, the lifting frame 21 is connected to the mounting base plate 100 by a calibration block 25, and the front end of the test shaft 23a is abutted against the top end of the calibration block 25.
