[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application includes a test frame, a camera testing assembly, and a carrier. A slide rail is mounted on the test frame, and the carrier is slidably mounted on the slide rail. The camera testing assembly includes a length testing camera, an image measuring instrument, and a mounting hole testing camera. The length testing camera, image measuring instrument, and mounting hole testing camera are spaced apart along the slide rail on the test frame to form inspection stations. This allows for automatic dimensional inspection of the servo motor, requiring only manual placement of the servo motor onto the carrier. The servo motor is transported to each inspection station via the carrier, and the length, flange face, and mounting holes of the servo motor are photographed and measured using the length testing camera, image measuring instrument, and mounting hole testing camera. This improves the efficiency of manual inspection, and the photographic measurement also enhances testing accuracy.

[0017] 2. Based on the foregoing, the carrier of this application is equipped with a carrier drive assembly, which includes a first ball screw pair, a first moving motor, a carrier mounting plate and a cable chain. The carrier mounting plate is slidably mounted on the slide rail by a slider, and the carrier mounting plate is fixedly connected to the nut end of the first ball screw pair. The first moving motor drives the screw to rotate and slide on the slide rail, so as to increase the sliding stroke of the carrier mounting plate through the first ball screw pair, thereby ensuring the relative position of the servo motor and the test camera and improving the accuracy of the photographic test.

[0018] 3. Building upon the foregoing, the carrier of this application includes several mounting blocks, which together form a mounting groove whose shape is adapted to the shape of the servo motor. This ensures the stability of the servo motor during testing, thereby guaranteeing the accuracy of the test results. Furthermore, when testing servo motors of different specifications and sizes, testing can be performed simply by replacing the carrier with a suitable one, demonstrating strong compatibility.

[0019] 4. Building upon the foregoing, the test frame housing the length measurement camera of this application is equipped with a moving component, including a guide rail, a second ball screw pair, a second moving motor, a motor mounting plate, and a second cable chain. The motor mounting plate is slidably mounted on the guide rail via a slider and is fixedly connected to the nut end of the second ball screw pair. Driven by the second moving motor, the motor mounting plate slides along the guide rail, thereby driving the length measurement camera to take a length photograph of the servo motor. Furthermore, the length measurement camera of this application is perpendicular to the axis along the length direction of the servo motor. This allows for better measurement distance between the length measurement camera and the servo motor during testing, especially for motors with large lengths, by sliding the motor mounting plate relative to the servo motor, thus improving the product's applicability.

[0020] 5. Building upon the foregoing, the test frame housing the image measuring instrument and the mounting hole test camera of this application is equipped with a mounting bracket. This mounting bracket is a gantry-type structure that spans across the upper side of the slide rail. When the carrier slides along the slide rail to the mounting bracket, the image measuring instrument aligns with the flange face of the servo motor, and the mounting hole test camera aligns with the mounting surface of the servo motor. This allows for adaptation adjustments to be made simply by changing the mounting positions of the image measuring instrument and the mounting hole test camera when testing different servo motors. It enables dimensional measurements of the motor at various positions, offering strong adaptability, minimal manual intervention, and high testing efficiency.

Measurement data can be uploaded via wireless or wired interfaces, achieving full data digitization of the testing process, traceability of measurement results, and automated testing.

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] Please see Figures 1-4 This embodiment discloses an automatic servo motor size detection device, including a test frame 1, a camera test assembly and a carrier 13.

The carrier drive assembly includes a first ball screw pair, a first moving motor 10, a carrier mounting plate, and a cable chain 9. The carrier mounting plate is slidably mounted on the slide rail 11 via a slider. To ensure that the length testing camera can effectively photograph the length of the servo motor, a backlight plate 3 is provided on the carrier mounting plate to ensure image clarity. The lead screw 12 of the first ball screw pair is rotatably mounted on the test frame parallel to the slide rail. The first moving motor is fixedly mounted on the test frame, and its power end is fixedly connected to the lead screw. The nut end of the first ball screw pair is fixedly connected to the carrier mounting plate. The cable chain is mounted on the test frame parallel to the slide rail. In addition, a position sensing block 15 is installed on the test frame corresponding to the detection station. A position sensor 16 is installed on the carrier mounting block, and the position sensing block is located within the movement trajectory of the position sensor.

[0029] Furthermore, in this embodiment, the length testing camera, image measuring instrument, and mounting hole testing camera of the camera testing component are all CCD testing cameras.

[0030] The carrier in this embodiment includes several mounting blocks 130, each mounting block is provided with a mounting slot, and the mounting slots of several mounting blocks form a mounting groove whose shape is adapted to the shape of the servo motor.

[0031] In this embodiment, the test frame housing the length testing camera is equipped with a moving component 5, the position of which constitutes a first testing station. The moving component includes a guide rail, a second ball screw pair, a second moving motor 4, a motor mounting plate, and a second cable chain. In this embodiment, the length testing camera is perpendicular to the axis of the servo motor's length direction. The motor mounting plate is slidably mounted on the guide rail via a slider, and the length testing camera is fixedly mounted on the motor mounting plate. The lead screw of the second ball screw pair is rotatably mounted on the test frame parallel to the guide rail. The second moving motor is fixedly mounted on the test frame, and its power end is fixedly connected to the lead screw. The nut end of the second ball screw pair is fixedly connected to the motor mounting plate. The second cable chain is mounted on the test frame parallel to the guide rail.

[0032] In this embodiment, the test frame housing the image measuring instrument and the mounting hole test camera is equipped with a mounting bracket 14, which forms the second inspection station. The mounting bracket has a gantry structure and spans the upper side of the slide rail. When the carrier slides along the slide rail to the mounting bracket, the flange face of the image measuring instrument corresponds to that of the servo motor, and the mounting hole test camera corresponds to that of the servo motor. In this embodiment, position sensing blocks are installed on the test frame at positions corresponding to the first and second inspection stations, and position sensors are installed on the carrier mounting blocks, with the position sensing blocks located within the movement trajectory of the position sensors.

The controller has a data storage module, and the length testing camera, image measuring instrument, mounting hole testing camera, and barcode scanner are electrically connected to the controller. The controller also has a data transmission module with wireless and / or wired transmission interfaces.

[0034] Working Principle: Before use, the automatic servo motor dimension detection device in this embodiment requires the tester to adjust the controller parameters according to the model and specifications of the servo motor under test. This controls the sliding stroke of the drive motor mounting plate of the second moving motor, ensuring that the length testing camera slides to a suitable position to take pictures of the servo motor. Additionally, based on the location of the servo motor's mounting holes and flange surface, the mounting positions of the image measuring instrument and the mounting hole testing camera are adjusted on the mounting frame to ensure that when the servo motor slides onto the mounting frame, the image measuring instrument and the mounting hole testing camera correspond to the mounting hole surface and flange surface of the servo motor.

[0035] In operation, the servo motor under test is first placed on the carrier manually or using a loading device. The tester then secures the servo motor to the mounting slot of the carrier to ensure it does not shift during testing. Next, the testing device is activated. The first moving motor rotates, driving the lead screw of the first ball screw pair to slide along the lead screw, which in turn moves the carrier mounting plate along the guide rail, moving the carrier to the first testing station. The second moving motor then rotates, driving the lead screw of the second ball screw pair to slide along the lead screw, which in turn moves the motor mounting plate along the guide rail, moving the length testing camera to a suitable position for photographic testing of the servo motor. After the length test is completed, the first moving motor is activated, driving the carrier mounting plate to slide to the second testing station, i.e., the location of the mounting bracket. Then, an image measuring instrument and a mounting hole testing camera photograph the servo motor, completing the testing of the flange face and mounting holes. After all tests are completed, the first moving motor is reset, which drives the carrier mounting plate to slide to the unloading station. The tester unloads the servo motor, then reassembles the new servo motor and repeats the test.
