Description

A weighing device for quickly checking the injection volume of the injection pump

technical field

The utility model relates to a weighing device for quickly checking the injection volume of an injection pump.

Background technique

Lithium batteries have the advantages of small size, large capacity, long service life, low self-discharge rate, no memory effect, and environmental protection. They are currently widely used in commercial vehicles, special vehicles, electric bicycles, energy storage systems, and medical equipment. At present, most lithium battery manufacturers usually use the method of sampling the injection volume of the injection pump one by one to check the injection pump of the injection machine, and then use electronic scales to weigh them one by one. This method takes a lot of time and affects production efficiency. And because no clean measuring tool is used in the sampling process, it is easy to cause pollution to the electrolyte, resulting in a serious waste of the electrolyte.

Utility model content

In order to achieve the above purpose, the utility model adopts the following technical scheme: it includes a carrier for placing a plurality of weighing cells, the carrier is in the shape of an open box, and the weighing cells include a A measuring cup below the liquid injection nozzle of the machine and a button sensor placed at the bottom of the measuring cup, the terminal of the button sensor is connected to a PLC control device, and the PLC control device is connected to a display device.

A cylinder is arranged at the upper center of the button sensor, and a cylindrical hole matched with the cylinder is arranged at the bottom of the measuring cup.

The button sensor is fixed on the bottom plate of the carrier by bolts.

Both sides of the carrier are respectively provided with handles.

The display device is integrated on the carrier.

It can be seen from the above technical scheme that the utility model adopts a button-type sensor to weigh the quality of the injection volume of the injection pump, and adjusts the injection pump according to the weighing quality displayed by the display device. Advantages of cleaning and recyclable electrolyte.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1 and Figure 2, a weighing device for quickly checking the liquid injection volume of the infusion pump includes a carrier 2 for placing multiple weighing units 1, the carrier 2 is in the shape of an open box, and the carrier The two sides of 2 are provided with handles 4 respectively. The weighing unit 1 includes a measuring cup 11 placed under the liquid injection nozzle of the liquid injection machine and a button sensor 12 placed at the bottom of the measuring cup 11. The terminal 121 of the button sensor 12 is connected to the PLC. The control device is connected, the PLC control device is connected with the display device 3 , and the display device 3 is integrated on the carrier 2 . Specifically, the carrier 2 is in an open shape with a plurality of weighing cells 1 built in, and the measuring cup 11 of each weighing cell 1 is placed under the liquid injection nozzle of the liquid injection machine to facilitate the liquid injection machine to measure the cups 11. Liquid is injected, and the quality of the liquid in the measuring cup 11 is transmitted to the PLC controller through the button sensor 12, and the PLC controller then feeds back the result to the display device 3, and the multiple weighing cells 1 are independent of each other.

Further, the button sensor 12 is fixed on the base plate of the carrier 2 by bolts, as shown in Figure 3, a cylinder 122 is provided at the top center of the button sensor 12, and a cylinder 122 is provided at the bottom of the measuring cup 11 to match the cylinder 122. The cylindrical hole forms a clearance fit between the measuring cup 11 and the button sensor 12, which facilitates the taking out of the measuring cup 11.

Working principle and working process of the present utility model are as follows:

Before operation, clean the measuring cups one by one, place the measuring cups with the button sensor, and then place the weighing device under the liquid injection nozzle of the liquid injection machine, so that the liquid injection nozzles correspond to the measuring cups one by one, and weigh them through the PLC controller. The device performs zero calibration. After the zero calibration is completed, the liquid injection pump of the liquid injection machine is started to inject liquid into the measuring cup. After the liquid injection is completed, the weighing value is read through the PLC controller, and the electrolyte in each measuring cup is recovered. Close the liquid injection pump that meets the requirements of the liquid injection volume, adjust the liquid injection volume of the liquid injection pump that needs to be adjusted according to the weighing value, and then perform zero calibration on the weighing device through the PLC controller. After the zero calibration is completed Start the liquid injection pump of the liquid injection machine to inject liquid into the measuring cup. After the liquid injection is completed, read the weighing value through the PLC controller. If each weighing value meets the requirements, the check is completed.

The beneficial effects of the utility model are as follows: 1) The utility model weighs the quality of the injection volume of the injection pump through a button-type sensor, and the weighing result is transmitted to the display device through the PLC controller, which can be intuitively measured according to the displayed value. The liquid injection pump is adjusted; 2) the utility model has the advantages of accurate weighing, simple operation and high efficiency; 3) the measuring cup of the utility model is easy to clean, and the electrolyte can be recycled; 4) the utility model can enable production personnel to Quickly check the injection volume of the injection pump of the liquid machine.
