Description

Technical Field

[0001] The present application relates to the technical field of electronic scale detection, and in particular to a weight loading device for electronic scale detection. Background Art

[0002] In the calibration and testing process of electronic scales, the traditional method usually adopts the method of manually loading weights. However, this method has problems such as cumbersome operation, low efficiency, and susceptibility to human factors. Therefore, the demand for automatic weight loading devices is becoming increasingly prominent. At present, there are some automatic weight loading devices on the market. These devices usually realize automatic loading and unloading of weights through driving mechanisms such as electric push rods or cylinders. However, these devices are often complex in structure and high in cost. In actual use, due to the influence of factors such as mechanical friction and driving mechanism accuracy, their loading accuracy still needs to be improved, which can easily lead to deviations in the test results of the electronic scale group.

[0003] After searching, the Chinese patent announcement number CN117870840A discloses an automatic calibration device for electronic scales, including a machine and a loading platform arranged on the machine, a slider is arranged above the loading platform, and the electronic scale to be calibrated is arranged on the loading platform; the machine is provided with an X-axis motion module, a Y-axis motion module and a Z-axis motion module, and the X-axis motion module and the Y-axis motion module drive the loading platform to move in the horizontal direction; a weight string is suspended below the slider, and the Z-axis motion module drives the slider and the weight string to move in the vertical direction, and a tension sensor is provided between the slider and the weight string. By adopting the above technical solution, under the drive of the X-axis motion module and the Y-axis motion module, the loading platform can drive the electronic scale to be calibrated to move in the horizontal plane, thereby adjusting the relative position of the weight string and the electronic scale in the horizontal direction, and the slider and the weight string move in the vertical direction under the drive of the Z-axis motion module, so that the weight string is close to or away from the electronic scale in the vertical direction. When the weight string is in a suspended state, the tension sensor will collect a value. When the weight string just touches the top of the electronic scale, the value will decrease. At this time, the distance between the bottom of the weight string and the electronic scale can be obtained by measuring the driving distance of the slider through the Z-axis motion module, thereby ensuring that the multiple sub-weights on the weight string can be placed on the electronic scale in turn, avoiding a single action of the Z-axis motion module causing multiple sub-weights to fall on the electronic scale at the same time, effectively improving the calibration efficiency of the electronic scale.

[0004] An automatic calibration device for electronic scales in the above-mentioned patent has the following shortcomings: in the above-mentioned patent, weights can be automatically added to the detection device by setting a weight string, but in actual operation, the weight string is relatively long. When detecting an electronic scale with a lower height, the weight string is prone to shaking. Once the weight string shakes, it will cause large errors in the detection of the electronic scale.
