[0032] In today's industrial automation and logistics sectors, rotating discs serve as key material handling and handling tools, used across various production lines, storage centers, and laboratory testing facilities. Their efficient and flexible rotational capabilities facilitate the optimization and efficiency improvement of material handling processes. However, with the advancement of refined and intelligent industrial production, a single rotational function is no longer sufficient to meet the complex and ever-changing operational demands. This is particularly true in scenarios requiring precise material measurement, where the limitations of traditional rotating discs are becoming increasingly prominent.

[0033] The core design of many current rotating disk systems, while ensuring accurate rotation, lacks the ability to instantly detect and record the weight of the material on it during rotation. Consequently, in practical applications, specialized weighing equipment often needs to be installed alongside the rotating disk to determine weight through non-contact measurement or manual transfer of materials to a weighing platform. This approach not only increases equipment procurement and maintenance costs, but also reduces overall work efficiency and space utilization due to the additional steps and space occupied by the equipment. It can even introduce errors, affecting weighing accuracy.

[0034] Figure 1 The figure schematically shows the structure of a weighing device according to an embodiment of the present invention. Figure 2The following schematically shows a structural diagram of a weighing device according to another embodiment of the present invention. Figure 1 and 2 As shown, the present invention provides a weighing device. The weighing device in the present invention includes a base 10, a rotating assembly and a weight detection assembly. The rotating assembly includes a rotating disk 21, a connecting member 22 and a driving member 23. The rotating disk 21 and the driving member 23 are respectively connected to the connecting member 22. The driving member 23 is driven and connected to the rotating disk 21 and can drive the rotating disk 21 to rotate. The rotating disk 21 is used to fix the object to be detected and to rotate the object to be detected. The weight detection assembly includes a weight sensor 31. The weight sensor 31 is arranged between the connecting member 22 and the base 10. The weight sensor 31 is used to detect the weight of the object to be detected rotated by the rotating disk 21.

[0035] According to the technical solution of the present invention, the base 10 is used to support the rotating component and the weight detection component. The rotating disk 21 can fix the part to be detected and can drive the part to be detected to rotate. The weight sensor 31 can detect the weight of the rotating part to be detected and can capture the weighing data in real time. When the rotating disk 21 rotates, the stability and accuracy of the measurement results can also be guaranteed.

[0036] Specifically, if Figure 1 and 2 As shown, in this embodiment, base 10 is the fundamental support component of the entire weighing device, securing the entire device to a laboratory platform or inspection table. By providing stable support, base 10 ensures the stability and reliability of the device during operation. Base 10 is provided with mounting slots that allow it to be secured to aluminum profiles or laboratory platforms.

[0037] Specifically, if Figure 1 and 2 As shown, in this embodiment, weight sensor 31 transmits the weight of the test piece to its load cell based on the changes in its strain gauge. The weight is then measured using the spring and strain gauge of weight sensor 31. When the test piece is subjected to external forces, the strain gauge deforms slightly, generating an electrical signal. Weight sensor 31 measures and records the weight of the test piece and transmits this data to digital weight transmitter 34 for further processing.

[0038] In some embodiments of the present invention, Figure 1 and 2As shown, the weight detection assembly also includes a first fixing plate 32 and a second fixing plate 33. The first fixing plate 32 is disposed between the connector 22 and the weight sensor 31, and the second fixing plate 33 is disposed between the base 10 and the weight sensor 31. In this embodiment, the second fixing plate 33 is an important component connecting the base 10 and the weight sensor 31, and can protect the weight sensor 31. In addition, the second fixing plate 33 is connected to the base 10 via four screws, providing a stable mounting base for the weight sensor 31. The design of the second fixing plate 33 takes into account the installation position and orientation of the weight sensor 31 to ensure accurate measurement.

[0039] Specifically, in this embodiment, first fixing plate 32 connects weight sensor 31 to the rotating assembly via connector 22. The design of first fixing plate 32 for weight sensor 31 requires consideration of the overall stability and force transmission of the device. Furthermore, first fixing plate 32 is connected to connector 22 via four screws.

[0040] In some embodiments of the present invention, Figure 3 As shown, a first protrusion 321 is provided on the side of the first fixing plate 32 facing the weight sensor 31, and a second protrusion 331 is provided on the side of the second fixing plate 33 facing the weight sensor 31. The weight sensor 31 is connected between the first protrusion 321 and the second protrusion 331. In this embodiment, the first protrusion 321 can reduce the connection area between the first protrusion 321 and the weight sensor 31, and the second protrusion can also reduce the connection area between the first protrusion 321 and the weight sensor 31, thereby making it easier for the weight sensor 31 to deform under force, thereby more accurately detecting the weight of the part to be detected.

[0041] In some embodiments of the present invention, Figure 3 As shown, the first protrusion 321 and the second protrusion 331 are staggered along the arrangement direction of the connecting member 22 and the base 10. In this embodiment, the above arrangement enables the connecting member 22 to stagger the direction of the force applied to the weight sensor 31 and the direction of the torque transmitted by the weight sensor 31 to the base 10, thereby making it easier for the weight sensor 31 to deform. The larger the deformation of the weight sensor 31, the more obvious the change in data, making it easier for operators to observe and read.

[0042] In some embodiments of the present invention, Figure 1 and 2As shown, the weight detection component also includes a digital weight transmitter 34, which is arranged on the base 10 and electrically connected to the weight sensor 31. The digital weight transmitter 34 is used to receive the electrical signal from the weight sensor 31 and convert it into a recognizable digital signal for display. In this embodiment, the digital weight transmitter 34 adopts Delta-Sigma analog-to-digital conversion and digital filtering processing technology. The weak weight signal output by the weight sensor 31 is digitally processed and output to the host computer via RS485 serial communication. The digital weight transmitter 34 is responsible for receiving the electrical signal transmitted by the weight sensor 31 and converting it into a recognizable digital signal for display or further processing. Through its connection with the weight sensor 31, it realizes real-time monitoring and recording of the weight of the part to be detected.

[0043] In some embodiments of the present invention, Figure 1 and 2 As shown, the rotating assembly also includes a reducer 24, which is connected to the side of the connecting member 22 away from the base 10. The reducer 24 has a first connecting end and a second connecting end. The first connecting end is transmission-connected to the driving member 23, and the second connecting end is transmission-connected to the rotating disk 21. In this embodiment, the reducer 24 is a curved gear reducer, which adopts a reduction ratio reduction mechanism. Through the deceleration and torque-increasing effect of the gears, the speed of the driving member 23 (motor) is reduced to the required working speed, and the output torque of the driving member 23 (motor) is amplified. The curved gear reducer plays the role of reducing the speed, increasing the torque and transmitting power in the device, and has the characteristics of high transmission efficiency, low noise, high reliability, etc. The design of the curved gear can reduce energy loss and vibration noise during the transmission process and improve transmission efficiency.

[0044] In some embodiments of the present invention, Figure 1 and 2 As shown, the rotating assembly also includes a coupling, with opposite ends of the coupling being transmission-connected to the driver 23 and the first connection end, respectively. In this embodiment, the coupling connects the driver 23 (servo motor) and the reducer 24, transmitting the power of the driver 23 to the reducer 24 and ensuring coaxiality and transmission accuracy between the two. The coupling also provides a certain buffering and shock-absorbing effect, reducing vibration and impact during the transmission process.

[0045] In some embodiments of the present invention, Figure 1 and 2 As shown, the rotating disk 21 is arranged on the side of the reducer 24 away from the connecting member 22. In this embodiment, the above arrangement can prevent the detected part from interfering with components such as the weight sensor 31 after being fixed on the rotating disk 21, thereby improving reliability.

[0046] In some embodiments of the present invention, the driver 23 is a servo motor. In this embodiment, a driver with closed-loop feedback for the servo motor receives pulses and then sends pulses to the motor. The motor operates, and the encoder reads the motor's position and feeds it back to the driver. The driver compares the sent and received data to see if they are consistent. If there is a deviation, the driver corrects the difference. If there is too much loss, an alarm is issued. The controller compares the encoder's feedback signal with a preset target signal and adjusts the output signal to ensure that the motor moves along the predetermined trajectory. This closed-loop feedback mechanism enables the servo motor to achieve precise control of its motion.

[0047] In some embodiments of the present invention, Figure 1 and 2 As shown, the rotating assembly further includes a fixing member 25, which is disposed on a side of the connecting member 22 facing away from the base 10 and is fixedly connected to the driving member 23. In this embodiment, the fixing member 25 can fix the driving member 23, further improving the stability of the driving member 23 during operation.

[0048] Furthermore, in this embodiment, rotating disk 21 is the actuator of the device and is connected to reducer 24 via flange 26. Driven by reducer 24, rotating disk 21 rotates at a predetermined speed and direction. Depending on the application scenario and requirements of the device, rotating disk 21 can be used to perform operations such as conveying, positioning, and processing parts to be inspected.

[0049] Traditional weighing equipment often measures weight in static or low-dynamic environments. This makes it difficult to accurately weigh parts while they are rotating, such as material trays on production lines and rotating test benches in laboratories. The present invention enables dynamic weighing of parts to be inspected while the rotating disk 21 is rotating, resolving the issues of difficult weighing and low weighing accuracy in dynamic environments.

[0050] This utility model utilizes a high-precision weight sensor 31 and a digital weight transmitter 34 to capture and process weighing data in real time. This ensures the stability and accuracy of measurement results even when the rotating disk 21 is rotating. The weight sensor 31 is calibrated to ensure accurate measurement data. The digital weight transmitter 34 converts analog signals into digital signals and connects to a host computer via the standard RS485 communication protocol, enabling remote transmission of weighing data, real-time monitoring, and intelligent analysis.

[0051] To ensure smooth rotation and precise positioning of the rotating disk 21, the present invention also integrates a servo motor and reducer 24. This closed-loop feedback motor enables high precision, rapid response, and stable operation. Real-time feedback and adjustment mechanisms ensure precise control of speed and position, ensuring the stability and accuracy of the rotating disk 21 during rotation. The present invention integrates the weighing mechanism, reducer 24, and rotating disk 21 into a single unit, reducing equipment footprint and simplifying installation and maintenance.

[0052] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
