[0002] During the production and installation of AGV wheels, abnormal installation, size design, errors, or poor flatness of the wheel surface itself can all cause the flatness of the wheel assembly to exceed the limit.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] This utility model provides an AGV wheel surface flatness detection device, such as Figure 1 As shown, the device includes a base plate 1; the base plate 1 is provided with a fixing component 2 for fixing the AGV trolley drive wheel device 4 and a detection component 3 for detecting the flatness of the wheel surface of the AGV trolley drive wheel device 4; the detection end of the detection component 3 and the fixing end of the fixing component 2 for fixing the AGV trolley drive wheel device 4 are on the same vertical line of gravity.

[0020] Specifically, in the process of inspecting the produced AGV drive wheel device 4, the AGV drive wheel device 4 is fixed on the fixing component 2. Through the function of the detection component 3, the flatness of the wheel surface of the AGV drive wheel device 4 on the fixing component 2 is detected, thereby obtaining a high-precision test result of the AGV drive wheel surface flatness test of the AGV drive wheel device.

[0021] Further, the detection component 3 includes: a first support rod 31, a second support rod 32, a first connecting rod, and a fixing frame 34 for fixing the detection sensor; one end of the first support rod 31 is detachably connected to the device base plate 1; one end of the second support rod 32 is detachably connected to the device top plate; one end of the first connecting rod is detachably connected to the other end of the first support rod 31; the other end of the first connecting rod is detachably connected to the other end of the second support rod 32; the fixing frame 34 is detachably connected to the first connecting rod, and the fixing frame 34 is located above the fixing component 2.

[0022] In Example 1, as Figure 2 As shown, the fixing frame 34 is installed on the first connecting rod through the overall support frame formed by the first support rod 31, the second support rod 32 and the first connecting rod, and the position is aligned with the AGV trolley drive wheel device 4 on the fixing component 2, thereby realizing the flatness test of the AGV drive wheel surface of the AGV trolley drive wheel device.

[0023] Furthermore, the fixing component 2 includes: a support block and a hinge seat fixing member 21 for fixing the AGV trolley drive wheel device 4; the hinge seat fixing member 21 is detachably connected to the device base plate 1; the hinge seat fixing member 21 is provided with at least one positioning pin hole 22; a positioning pin can be provided in the positioning pin hole 22 to fix the AGV trolley drive wheel device 4 on the hinge seat fixing member 21; the support block is detachably connected to the hinge seat fixing member 21 and is located on one side of the hinge seat fixing member 21.

[0024] In Embodiment 2, the hinge seat fixing component 21 is used to fix the AGV trolley drive wheel device 4. The hinge seat fixing component 21 is provided with positioning pin holes 22 that are adapted to different models and sizes. When installing the AGV trolley drive wheel device 4, the AGV trolley drive wheel device 4 and the hinge seat fixing component 21 are connected and fixed through the mounting positioning pins on the corresponding positioning pin holes 22, thereby achieving the effect of detection and installation fixation. The support block can support the AGV trolley drive wheel device 4 to avoid shaking caused by the operation of the AGV trolley drive wheel device 4 during the test, which would result in large measurement data errors and ineffective detection.

[0025] Furthermore, the fixing frame 34 is equipped with two photoelectric sensors 35, which correspond to the two wheel surfaces of the AGV trolley drive wheel device 4 respectively.

[0026] In the preferred embodiment, the optimal number of photoelectric sensors 35 installed on the mounting bracket 34 is two. The photoelectric sensors 35 are installed with a spacing distribution on the same axis. The test points of the two sensors are close to the wheel edges A and B. If the wheel is installed crookedly, the difference between A and B can be maximized, which corresponds to the wheel surface distribution distance of the AGV drive wheel. The photoelectric sensor 35 is a TOF photoelectric ranging sensor.

[0027] Furthermore, a main control component is also provided on the base plate 1 of the device; the main control component is electrically connected to two photoelectric sensors 35 respectively.

[0028] Specifically, the sensor is connected to the main control component via a 485 module. Therefore, the main control component can be understood as the main control unit. In specific applications, the main control component can be a microcomputer or other control device with processing and computing functions.

[0029] Specifically, the main control component on the device base plate 1 is connected to the AGV trolley drive device to enable the AGV trolley drive device to run at a constant speed during the detection process, thereby realizing the detection of wheel surface flatness during the test. The data of the detection component 3 is transmitted to the main control component for summary processing, so that the data can be uploaded to the system (including but not limited to the platform and host computer) in the future, and the managers can view the data in real time.

[0030] In the specific implementation process, the AGV trolley drive device is installed on the fixed component 2, and the detection component 3 is finely adjusted to align the detection end of the photoelectric sensor 35 with the wheel surface of the AGV trolley drive device in order to start the test;

[0031] The main control component is electrically connected to the AGV drive unit under test, controlling the drive wheels on the AGV drive unit to rotate at a set speed. At the same time, the photoelectric sensor 35 of the detection component 3 starts to collect data and feeds the data back in real time.

[0032] Based on the collected data, the first photoelectric sensor 35 collects and transmits data from one of the wheel surfaces. The main control component calculates the maximum and minimum distance values ​​after the wheel rotates one revolution (or several revolutions) and makes the difference. If the difference exceeds the set threshold, the wheel may have uneven areas on the travel point line or the wheel design circle value may be abnormal.

[0033] The second photoelectric sensor 35 collects and transmits data from another wheel surface. The main control component calculates the maximum and minimum distance values ​​of the wheel rotating one revolution (or several revolutions) and makes the difference. When the difference between the two exceeds the set threshold, the wheel may have uneven areas on the travel point line or the wheel design circle value may be abnormal.

[0034] When summarizing the final data, the data collected by the first photoelectric sensor 35 and the second sensor are obtained by subtracting the data from two points on the same axis. As real-time data, the main control component calculates the difference between the test values ​​of the data from the first photoelectric sensor 35 and the second sensor. When the difference exceeds the set threshold, it may indicate that the wheel has an installation abnormality or an abnormality in the wheel itself, which may have caused a conical surface to form on the rotation arc, thereby realizing the flatness test of the AGV trolley drive device.

[0035] This utility model discloses an AGV wheel surface flatness detection device. Through a high-precision photoelectric ranging sensor installed on the fixing frame 34, it can perform high-precision detection on the flatness of the AGV drive wheel surface, ensuring that after the drive wheel assembly is installed, the wheel can travel along the predetermined route without deviation, thereby increasing the service life and scene adaptability of the wheel and minimizing the driving deviation failure rate of the AGV.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
