It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model embodiment provides a detection device for optical modules. Please refer to [link / reference]. Figure 1 and Figure 2 It includes: an X-axis assembly 2 and a mounting bracket 7, a Y-axis assembly 3 mounted on the X-axis assembly 2, and a Z-axis assembly mounted on the Y-axis assembly 3; the mounting bracket 7 is mounted on the Z-axis assembly, and a detection component and a laser displacement sensor 10 are mounted on the mounting bracket 7, with the detection component and the laser displacement sensor 10 arranged close to each other.

[0023] like Figure 1 and Figure 2As shown, the X-axis assembly 2 provides the basis for the entire detection device to move in the horizontal direction (X direction). The Y-axis assembly 3 is mounted on the X-axis assembly 2 and can move in the horizontal direction (Y direction) perpendicular to the X-axis. The Z-axis assembly is mounted on the Y-axis assembly 3 and can move in the vertical direction (Z direction). These three axis assemblies cooperate with each other to form a motion system in three-dimensional space, enabling the components mounted on the Z-axis assembly to move flexibly in three-dimensional space.

[0024] The mounting bracket 7 serves as the mounting carrier for the detection component and the laser displacement sensor 10, securely connecting them to the Z-axis assembly, enabling the detection component and the laser displacement sensor 10 to move in three-dimensional space along with the Z-axis assembly.

[0025] The detection component is used to perform visual inspection and other detection operations on the optical module, and to acquire image information of the optical module. The laser displacement sensor 10 is used to sense the position information of the entire device in real time and to feed the position signal back to the control system. The two are set close to each other so that the laser displacement sensor 10 can accurately obtain relevant information about the position of the detection component during the detection process and adjust the position of the device in a timely manner.

[0026] Specific process: The operator starts the detection device, the control system initializes, and each axis assembly (X-axis assembly 2, Y-axis assembly 3, Z-axis assembly) returns to its initial position. The detection assembly and laser displacement sensor 10 enter standby mode. The laser displacement sensor 10 starts working, sensing the current position information of the device in real time and feeding this information back to the control system. The control system calculates the target position that the detection assembly needs to reach based on the preset detection program and the position information of the optical module. Then, it controls the X-axis motor 202, Y-axis motor 302, and Z-axis motor 6 to rotate respectively. The X-axis motor 202 drives the X-axis rod 203 to rotate, causing the X-axis guide block 204 to move on the X-axis seat 201, thereby moving the Y-axis assembly 3 in the X direction; Y The X, Y, and Z axis motors 302 drive the Y-axis rod to rotate, causing the Y-axis guide block 304 to slide on the Y-axis slide rail 303, thus moving the Z-axis assembly in the Y direction. The Z-axis motor 6 drives the Z-axis seat 5 to move in the vertical direction, eventually moving the fixed frame 7 (carrying the detection assembly and laser displacement sensor 10) to the vicinity of the target position. When approaching the target position, the laser displacement sensor 10 continuously feeds back position information. The control system further fine-tunes the movement of the X, Y, and Z axis assemblies based on the feedback information, so that the detection assembly (camera 8 and lens 9) is accurately aligned with the part of the optical module to be detected. Then, the detection assembly starts to work, the camera 8 captures an image of the optical module, and transmits the image information to the control system for analysis and processing, completing the inspection tasks such as appearance inspection.

[0027] Please see Figure 1 and Figure 2The detection component includes a camera 8 and a lens 9 mounted on a mounting frame 7. The camera 8 and lens 9 are mounted one above the other. The mounting frame 7 is configured as an L-shaped structure. The detection component and the laser displacement sensor 10 are both mounted on the horizontal arm of the mounting frame 7. The vertical arm of the mounting frame 7 is mounted on the Z-axis component.

[0028] like Figure 1 and Figure 2 As shown, camera 8 is used to capture image information of the optical module and is a key device for acquiring detection data; lens 9 plays the role of focusing and imaging. Together with camera 8, it can clearly present the details of the optical module. The one-on-one installation method makes the camera 8 and lens 9 more compact in structure, which is convenient for installation and debugging. At the same time, it is also conducive to ensuring the stability and accuracy of imaging. The focus is on using camera 8 and lens 9 to detect the optical module, which will not be described in detail in this embodiment.

[0029] The L-shaped mounting bracket 7 provides a reasonable installation space layout for the detection component and the laser displacement sensor 10. Its horizontal arm is used to install the detection component and the laser displacement sensor 10, while the vertical arm is used to connect with the Z-axis component, fixing the entire mounting bracket 7 on the Z-axis so that the detection component and the laser displacement sensor 10 can move in the vertical direction with the Z-axis component.

[0030] Please see Figure 1 and Figure 2 The X-axis assembly 2 includes an X-axis seat 201 with a cavity inside. The X-axis assembly 2 also includes an X-axis motor 202 mounted on one end of the X-axis seat 201 and an X-axis rod 203 connected to the output end of the X-axis motor 202. One end of the X-axis rod 203 extends into the interior of the X-axis seat 201, and an X-axis guide block 204 is provided on the exterior of the X-axis rod 203. The Y-axis assembly 3 includes a Y-axis seat 301 mounted on the X-axis guide block 204 and a Y-axis slide rail 30 on the Y-axis seat 301. 3. A Y-axis guide block 304 slides on the Y-axis slide rail 303. The Y-axis assembly 3 also includes a Y-axis motor 302 installed at one end of the Y-axis seat 301 and a Y-axis rod connected to the output end of the Y-axis motor 302. The Y-axis guide block 304 is located outside the Y-axis rod. A column 4 is fixed on the Y-axis guide block 304. The Z-axis assembly includes a Z-axis seat 5 located on one side of the column 4 and a Z-axis motor 6 installed on the Z-axis seat 5. A fixing bracket 7 is located on the Z-axis seat 5. A base 1 is fixed at the bottom of the X-axis seat 201.

[0031] like Figure 1 and Figure 2 As shown, the X-axis mount 201 serves as the basic support structure for the X-axis assembly 2, providing a stable mounting platform for the entire X-axis assembly 2. The cavity formed inside can be used to arrange cables, place some transmission components, or reduce the overall weight.

[0032] X-axis motor 202 is the power source of X-axis assembly 2. It drives X-axis rod 203 to rotate by outputting rotational power. X-axis rod 203 converts the rotational motion of the motor into linear motion (usually through lead screw transmission, etc.). X-axis guide block 204 then moves linearly along X-axis rod 203, thereby driving other components (such as Y-axis assembly 3) installed on X-axis guide block 204 to move in the X-axis direction.

[0033] The Y-axis seat 301 is fixed on the X-axis guide block 204, and moves along the X-axis direction as the X-axis guide block 204 moves. The Y-axis slide rail 303 provides a sliding track for the Y-axis guide block 304, enabling the Y-axis guide block 304 to move linearly in the Y-axis direction.

[0034] Y-axis motor 302 provides power to Y-axis assembly 3, driving the Y-axis rod to rotate. The Y-axis rod converts the rotational motion into the linear motion of Y-axis guide block 304, causing Y-axis guide block 304 to move along Y-axis slide rail 303 in the Y-axis direction, thereby driving the components (such as column 4 and Z-axis assembly) installed on Y-axis guide block 304 to move in the Y-axis direction.

[0035] The column 4 acts as a bridge connecting the Y-axis guide block 304 and the Z-axis assembly, transmitting the movement of the Y-axis guide block 304 to the Z-axis assembly and providing stable support for the Z-axis assembly.

[0036] Z-axis mount 5 is fixed to one side of column 4, providing a mounting base for Z-axis motor 6 and mounting bracket 7. Z-axis motor 6 drives mounting bracket 7 to move linearly in the Z-axis direction, thereby driving the detection component and laser displacement sensor 10 mounted on mounting bracket 7 to move in the vertical direction.

[0037] The base 1 is the supporting foundation of the entire testing device, which fixes the entire device on the workbench or other supporting structure to ensure the stability of the testing device during operation.

[0038] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
