the utility model provides a system for battery is annotated to control calamine cream, includes the calamine cream bucket, connects the calamine cream filling tube that connects out below the calamine cream bucket and connects filling syringe needle, filling pump, the filling of setting on the calamine cream filling tube at the calamine cream filling tube end servo, corresponds the cam that is used for driving the battery removal that sets up in calamine cream filling tube below to and fix the battery slide bar that is used for placing the battery on the cam, battery and calamine cream filling tube still include according to the synchronous operation of corresponding central angular velocity: the stroke control module comprises a filling servo stroke control module and a vertical stroke control module;

and the vertical stroke control module is used for controlling the stroke of the cam to descend according to a preset descending stroke when the battery reaches a preset zinc paste initial filling position.
The filling of the cream into each cell is carried out by means of a cam in cooperation with a filling servo and a filling pump arranged on the cream filler pipe. When the battery steel shell enters a filling station, the corresponding cam curve moves upwards, the rotary valve of the corresponding filling pump is opened, the cam drives the battery steel shell to be lifted to a filling position through the battery slide bar, filling is started in a servo mode, the battery and the zinc paste injection pipe synchronously move around the center of the cam, the battery starts to move downwards, when the battery descends to a preset position, filling is completed, the cam is paused, the filling pump is closed, the filling servo returns to a zero position, and the next cycle is started.
Further, the filling servo stroke control module comprises:

the filling quantity control unit is used for controlling the filling servo to rotate according to the preset rotation stroke of the filling servo;
and the filling ending control unit is used for controlling the filling pump to be closed and stopping filling when the battery reaches a preset zinc paste ending filling position.
Further, the vertical stroke control module includes:
the cam stroke control unit is used for controlling the battery to descend according to a preset descending stroke when the battery reaches a preset initial zinc paste filling position;
and the stroke end control unit is used for controlling the battery to stop running up and down when the battery reaches the preset zinc paste end filling position.
Furthermore, the preset rotation stroke of the filling servo stroke control module and the preset descending stroke of the vertical stroke control module are in a preset curve relationship.
As shown in fig. 4, in which the slope below the battery represents the running locus of the battery descending. At the top of the slope, i.e. when the battery is raised to the predetermined initial location for filling with the calamine cream, the calamine cream injection tube extends into the battery close to the bottom thereof and is connected to a filling pump serving for filling through the upper part thereof. At the moment, a knob valve of the filling pump is opened, the battery starts to run downwards, when the battery descends downwards along with the stroke of the cam, the filling servo operation is carried out, the zinc paste is filled into the battery, and in the whole zinc paste filling process, a certain distance is kept between a zinc paste filling pipe and the liquid level of the zinc paste.
In the embodiment, the distance between the zinc paste injection pipe and the zinc paste in the battery is kept constant by controlling the stroke of the filling servo and the stroke of the cam.
In order to achieve matching between the filling servo stroke and the cam stroke, the preset rotation stroke of the filling servo stroke control module and the preset descending stroke of the vertical stroke control module in the embodiment are in a preset curve relationship.
The preset curve relation is obtained by firstly obtaining a displacement dx of a group of batteries descending and a displacement dy of a filling servo motor rotating; the filling servo motor rotates by a displacement dy by acquiring the descending displacement dx of the plurality of groups of batteries; the functional curve relation between the battery descending stroke and the filling servo rotating stroke under the current state can be obtained, wherein the obtained rotating displacement of the filling servo motor and the obtained battery descending displacement are both obtained by a motion controller, and the obtaining unit is very small and is in a micron order;
the function curve relationship between the cam stroke and the filling servo rotation stroke in the embodiment is as follows: y is ax5+bx4+cx3+dx2+ex+f。
The descending stroke of the battery and the rotation stroke of the filling servo are correspondingly controlled according to the function curve, so that the problem of the distance between a zinc paste injection pipe and the zinc paste liquid level in the battery is solved, and the problem of poor zinc paste injection effect when the descending speed of the battery changes is also solved.
Furthermore, the battery descending stroke and the filling servo rotating stroke are matched, so that the battery descending speed is convenient to change, and the speed is not required to be further adjusted to be matched with the filling speed.
The effect and efficiency of zinc paste injection are improved.
Example two
This embodiment provides a method of controlling the injection of calamine into a cell, as shown in fig. 5, comprising the steps of:
s1: judging whether the battery reaches a preset initial filling position of the zinc paste or not;
s2: if so, controlling the battery to descend according to a preset descending stroke, and controlling the filling servo to rotate according to a preset rotating stroke;
s3: recording the descending preset displacement of the plurality of groups of batteries and the corresponding preset rotary displacement of the filling servo rotation;
s4: substituting the preset descending displacement of the descending of the multiple groups of batteries and the preset rotating displacement of the corresponding filling servo rotation into a preset algorithm to obtain a preset curve relation between the preset descending displacement of the descending of the batteries and the preset rotating displacement of the corresponding filling servo rotation;
s5: and controlling the descending of the battery and the rotation of the filling servo to correspondingly descend and correspondingly rotate according to a preset curve.
In the prior art, the speed of descending operation of the battery and the speed of a filling servo motor on a filling pump are set in a linear relationship, and the disadvantage of the arrangement is that when the speed of descending operation of the battery changes or a zinc paste filling machine is started and stopped, the zinc paste filling effect is poor, and sometimes the zinc paste can not pass through a needle or be hollow.
The method for controlling the zinc paste to be injected into the battery adopts the matching of the descending displacement of the battery and the rotating distance of a filling servo motor for injecting the zinc paste.
I.e. the battery is lowered by a small displacement dx and the filling servomotor is rotated by a small distance dy (dx, dy are typically in the order of microns due to the high precision of the motion controller).
By acquiring multiple groups (dx, dy), a curve with the best effect can be drawn.
Wherein the relation between dx and dy is y ═ ax5+bx4+cx3+dx2+ ex + f and a, b, c, d, e, f are determined by the surface of the mechanical structure, the curve being exactly opposite to the trajectory of the battery descent.
The distance of battery decline and filling servo motor's rotation distance move according to this curve, have solved the battery decline and have been the problem that annotate the calamine cream effect not good when carousel motor speed changes, have improved product quality by a wide margin. In addition, the operation speed of the turntable motor is convenient to change, and the linear value does not need to be adjusted in order to match the rotation speed of the filling servo motor.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
