Example Embodiment

[0033] Example 1:

[0034] like figure 1As shown, this embodiment provides a liquid metering pump. The liquid metering pump is driven by a driving device 300, which drives the plunger 200 to move a preset distance relative to the pump body 100 according to the amount of the perfusion liquid, and cooperates with the liquid circuit control device at the same time. In the control action of 400, when the plunger 200 moves a preset distance in the direction opposite to the direction of the pump body 100, the liquid circuit control device 400 cuts off the liquid outlet passage of the pump body 100 and communicates with the liquid inlet passage of the pump body 100 to make A specific amount of liquid to be metered enters the liquid metering pump, and when the plunger 200 moves a preset distance in the direction of the pump body 100, the liquid circuit device cuts off the liquid inlet passage of the pump body 100 and communicates with the liquid outlet passage of the pump body 100 so ...

Example Embodiment

[0046] Example 2

[0047] like Figure 2 to Figure 4 As shown, this embodiment is optimized on the basis of Embodiment 1, wherein the driving device 300 includes a motor 310, a ball screw 320 and an output part 330, and the motor 310 is used to drive the ball screw 320 through the output part 330 drives the plunger 200 to perform a reciprocating linear motion relative to the pump body 100 . During operation, the motor 310 is connected with the ball screw by the coupling, and the nut in the ball screw is connected with the output part 330 . The motor 310 drives the lead screw to rotate, the lead screw rotates to drive the nut to reciprocate linear motion, the nut drives the output part 330 to reciprocate linear motion, and finally the output part 330 drives the plunger 200 to reciprocate linear motion. Therefore, by controlling the rotation angle of the motor 310, the distance the plunger 200 moves can be controlled. Because the ball screw 320 drives accurately, it can effec...

Example Embodiment

[0053] Example 3

[0054] like figure 1 As shown, this embodiment is further optimized on the basis of Embodiment 2. In this embodiment, the liquid metering pump includes a plurality of pairs of pump bodies 100 and plungers 200 arranged side by side in a direction perpendicular to the guiding direction of the guide mechanism, and a connecting rod 333 corresponding to each plunger 200 one-to-one , a first joint bearing 331 and a second joint bearing 332 , and each of the plungers 200 is connected with its corresponding first joint bearing 331 and the second joint bearing 332 through its corresponding connecting rod 333 .

[0055] In order to improve the efficiency of liquid perfusion while ensuring the accuracy of liquid perfusion, this embodiment adopts the solution of driving multiple metering pumps by the same driving device 300, and the plunger 200 of each metering pump is equipped with a set of first joint bearings 331 and the second joint bearing 332, so that each plung...

Abstract

The invention provides a liquid metering pump, an electrolyte filling device and a liquid filling method and relates to the technical field of liquid metering pumps. The liquid metering pump comprisesa pump body, a plunger, a driving device and a liquid path control device. The electrolyte filling device comprises the liquid metering pump. The liquid filling method comprises the following steps:cutting off a liquid outlet channel of the pump body and connecting a liquid inlet channel of the pump body; controlling the driving device drive the plunger to move for a first preset distance; cutting off the liquid inlet channel of the pump body and connecting the liquid outlet channel of the pump body; and controlling the driving device drive the plunger to move for a second preset distance. The liquid metering pump, the electrolyte filling device and the liquid filling method can solve the technical problems that the liquid filling quantity of the existing liquid metering pump cannot be rapidly and flexibly changed according to production demands, the adjusting time of the liquid filling quantity is long, and great materials are wasted in the adjusting process.

Description

technical field [0001] The invention relates to the technical field of liquid metering pumps, in particular to a liquid metering pump, electrolyte filling equipment and a liquid filling method. Background technique [0002] Many products require accurate injection of specific liquids during production. For example, in the production of lithium batteries, a specific amount of liquid is often required to be accurately injected in medical metering and perfusion. In the prior art, an electric liquid injection pump is generally used to inject liquid. Although the accuracy is controllable, in some production processes, when the production requirements such as product models change, the injection volume of the injected liquid is required to be changed accordingly. , while electric liquid injection pumps mostly use manual adjustment to change the injection volume. Due to the high accuracy of liquid injection volume, it takes a long time for professionals to stabilize the measurement...
