Description

Technical Field

[0001] The utility model relates to the technical field of weighing, in particular to a weighing device and a weighing system. Background Art

[0002] A balance that uses electromagnetic force to balance the weight of the object being weighed is called an electronic balance. The characteristics of an electronic balance are accurate and reliable weighing, fast and clear display, automatic detection system, simple automatic calibration device, overload protection and other devices. The higher the accuracy of the electronic balance, the easier it is to be disturbed by external factors during weighing. The influence of external airflow or dust will cause deviation in weighing data. Therefore, electronic balances are equipped with windshields to make the weight of the weighed object more accurate.

[0003] In the related art, the sample to be tested is generally placed on a scale for weighing by manual operation, and manual sampling is performed again after the weighing is completed. However, with the continuous increase in testing needs and the complexity of testing items, this operation mode that relies entirely on personnel has gradually exposed many disadvantages. In the process of manual weighing, the staff needs to open the door panel of the wind shield first, then put the sample on the scale for weighing, and also need to open the door panel after the weighing is completed and complete the sampling and close the door panel again to ensure the sealing state of the wind shield. This operation method seriously affects work efficiency. Utility Model Content

[0080] Alternatively, a plurality of grooves 10 may be arranged at intervals along a straight line or in a matrix.

[0081] In this embodiment, a plurality of grooves 10 are provided and arranged at intervals, so that weights of different specifications or for different purposes can be stored in categories, which are convenient for quick access and identification, and further improve work efficiency and user experience.

[0082] In some embodiments, it also includes:

[0083] The frame 11 is arranged on one side of the balance 1 , and the driving member 5 is connected to the frame 11 .

[0084] Optionally, the frame 11 may be configured as an aluminum alloy structure.

[0085] In this embodiment, the setting of the frame 11 provides a stable installation base for the driving member 5, so that the driving member 5 can work more stably and reliably, and also enhances the structural strength and stability of the entire weighing device.

[0086] In some embodiments, the frame body 3 is provided with a guide groove at the edge position of the cover body 2, and the guide groove constitutes a guide rail. The door panel 4 can be slidably inserted into the guide groove, and the door panel 4 is in sliding contact with the inner wall of the guide groove.

[0087] Optionally, a frame 3 structure can be set at the edge position of the cover body 2, which can stabilize the cover body 2 and enhance the sealing effect.

[0088] In this embodiment, by setting a guide groove as a guide rail on the frame 3 at the edge position of the cover body 2, the sliding of the door panel 4 is smoother and more stable, which ensures the sealing effect between the door panel 4 and the cover body 2, reduces the friction and wear between the door panel 4 and the cover body 2, and extends the service life.

[0089] According to an embodiment of the present utility model, on the other hand, a weighing system is provided, including a support frame 12, a weighing device, a manipulator and a controller.

[0090] The support frame 12 is suitable for carrying a weighing device.

[0091] The manipulator is suitable for placing the sample into the cover 2 of the weighing device.

[0092] The controller is electrically connected to the manipulator and the driving member 5 of the weighing device, and is suitable for controlling the driving member 5 to drive the door panel 4 of the weighing device to slide and controlling the manipulator to grab the sample.

[0093] In this embodiment, the setting of the weighing system realizes a fully automated process from sample placement to weighing and then sampling, greatly improving work efficiency and weighing accuracy. The controller's precise control of the manipulator and the drive member 5 ensures the smooth progress of the weighing process, and can record the weighing information in real time, which is convenient for subsequent data processing and analysis.

[0094] In some embodiments, the controller is electrically connected to the balance 1 of the weighing device and is suitable for recording weighing information of the balance 1 .

[0095] In this embodiment, the real-time recording and storage of weighing information is achieved through the electrical connection between the controller and the balance 1. This function not only facilitates the subsequent processing and analysis of data, but also improves the traceability and reliability of the weighing process.

[0096] In some embodiments, the controller first performs initialization operations, including self-test, parameter loading, etc., to ensure that each component is in normal working condition. When the balance 1 receives a signal that a sample needs to be weighed (such as triggered by an external button, sensor or host computer instruction), the controller receives this signal and prepares to execute the weighing process. The controller controls the balance 1 to perform a peeling operation, that is, to clear the current indication of the balance 1 to prepare for the upcoming weighing. The controller sends an instruction to the driver 5, and the driver 5 drives the door panel 4 to slide along the guide rail to the second position (i.e., the opening is open) to prepare for the manipulator to place the sample. After receiving the instruction from the controller, the manipulator grabs the sample from the preset position and places it in the weighing area of ​​the balance 1. At the same time, the photoelectric sensor detects whether the sample is in place and feeds back the signal to the controller. After the controller receives the signal that the sample is in place, it sends an instruction to the driver 5 again, and the driver 5 drives the door panel 4 to slide to the first position (i.e., the opening is closed) to ensure that the weighing process is not disturbed by the outside world. The balance 1 performs a weighing operation, and after the value is stable, the sample mass is transmitted to the controller. The controller records this mass data and determines whether it meets the weighing requirements. If the weighing meets the requirements, the controller again sends a command to the driver 5 to open the door panel 4, and then controls the manipulator to take the sample from the balance 1 and put it back to the preset position. After the manipulator completes the sampling, the controller controls the driver 5 to close the door panel 4 and reset the system to the initial state, waiting for the next weighing operation. The controller processes the recorded weighing data (such as storage, display, upload, etc.) and outputs it to the host computer or other devices as needed.

[0097] In this embodiment, the automatic weighing operation in the fully automated inspection process can be connected, which solves the problem of human resource waste caused by the need for human participation in the fully automated inspection process, so as to realize continuous inspection of the automatic inspection workstation and improve the inspection efficiency. The entire inspection process is visually monitored and controlled by the human-computer interaction interface to more perfectly realize the continuous inspection of the automatic inspection workstation to improve the inspection efficiency.
