[0034] A lithium battery mainly consists of structures such as a housing, a positive electrode plate, a negative electrode plate, and electrode tabs, and an electrolyte is injected into the housing. In the lithium battery manufacturing industry, an injection machine is usually used to inject the electrolyte into a single cell. In order to ensure that an equal amount of electrolyte is injected into each cell, an electronic scale is needed to weigh the single cell after the electrolyte is injected to ensure that the weights of each single cell after the electrolyte is injected are close to each other.

[0035] Among them, in order to ensure the accuracy of the weighing of the electronic scale, the electronic scale needs to be calibrated regularly. At present, the calibration operation of the electronic scale in the industry is basically completed manually by workers. Since there is a large amount of repetitive labor in the calibration operation, it not only greatly wastes human resources, but also increases the workload of the operators, taking a lot of time and effort.

[0036] Therefore, in order to improve the automation level of calibration operations, avoid a large amount of repetitive labor, improve the utilization rate of human resources, relieve the workload of operators, and make calibration operations time-saving and labor-saving, this embodiment provides an automatic calibration device for weighing equipment.

[0037] like Figure 1 As shown, the automatic calibration device for weighing equipment includes a platform component 1, a driving component 2, a sensing component 3 and a grabbing module. The platform component 1 includes a platform plate 11, a first bearing plate 12 and a second bearing plate 13. The first bearing plate 12 is fixedly connected to the platform plate 11 and is used to carry the weighing equipment 100. The second bearing plate 13 is arranged on the platform plate 11 and can be lifted and lowered along a first direction, and is located on the side of the first bearing plate 12 away from the platform plate 11. The second bearing plate 13 is used to carry a standard part 200. The driving component 2 includes a driving member 21 and a lifting plate 22. The lifting plate 22 is arranged between the first bearing plate 12 and the platform plate 11 and is connected to the second bearing plate 13.

The sensing component 3 includes a sensing probe 31 and a detection member 32. The detection member 32 is connected to the second bearing plate 13. The sensing probe 31 is used to sense the position of the detection member 32 so as to control the working state of the driving member 21. The grabbing module is used to grab the standard part 200.

[0038] By setting a grabbing module and a driving member 21 controlled by a sensing probe 31, when the weighing device 100 needs to be calibrated, the standard member 200 can be grabbed onto the second carrying plate 13 by the grabbing module, and then the second carrying plate 13 will be driven by the driving member 21 to approach the weighing device 100 located on the first carrying plate 12, until the sensing probe 31 senses the detection member 32 connected to the second carrying plate 13, and then controls the driving member 21 to change the working state, so that the driving member 21 no longer applies a force to the second carrying plate 13, and at this time, under the action of gravity, the second carrying plate 13 falls freely on the weighing device 100, so that the weighing device 100 completes the calibration operation according to the pressure it bears at this time. Thereby, the automation degree of the calibration operation is improved, the operator is prevented from performing a large amount of repetitive labor, the utilization rate of human resources is effectively improved, the workload of the operator is relieved, and the calibration operation is time-saving and labor-saving.

[0039] In this embodiment, the driving member 21 is a double-acting hydraulic cylinder. When the driving member 21 drives the lifting plate 22 to move up and down, one of the two oil ports of the driving member 21 is for oil inlet and the other is for oil outlet. By changing the direction of oil inlet and outlet, the movement trend of the lifting plate 22 can be changed. When the induction probe 31 detects the detection member 32, the induction probe 31 will transmit a signal into the control system (not shown in the figure). At this time, the control system will control both oil ports of the driving member 21 to be in the oil outlet state, so that the driving member 21 no longer exerts any force on the lifting plate 22. At this time, under the action of gravity, the second bearing plate 13 freely falls onto the weighing device 100 to assist the weighing device 100 in calibration operations. Among them, the control system can be a centralized or distributed controller. For example, the control system can be a single microcontroller or composed of multiple microcontrollers. A control program can run in the microcontroller to control the operation of the grasping module and the change of the state of the driving member 21. In this embodiment, the grasping module is a manipulator (not shown in the figure), the weighing device 100 is an electronic scale, and the standard part 200 is a single battery with a standard weight after liquid injection.
