Example 1
The embodiment of the application provides an automatic calibration method for glue dispensing valve glue amount, as shown in fig. 1, comprising the following steps:
step S1, setting a point glue valve parameter; wherein, dispensing valve parameters include at least: initial parameters, target weight parameters range S min ，S max ]Glue weight adjustment parameter Range [ W ] L ，W H ]Valve opening time t, and valve opening adjustment increment tk.
In the present embodiment, S min Is the minimum value of the target adhesive weight, S max For the maximum value of the target glue weight, W L Is the lower limit value of the adhesive weight, W H The upper limit value of the adhesive weight and the lower limit value W of the adhesive weight L Is the minimum value S of the target adhesive weight min Floating deviation extending to the extension direction, and upper limit value W of glue weight H Is the maximum value S of the target adhesive weight max Floating bias to epitaxial direction S min ＞W L ，S max ＜W H . Further, the initial parameters include fixed parameters of the dispensing valve, such as a rising time t1 of the dispensing valve and a falling time t2 of the dispensing valve.
And S2, controlling at least one dispensing valve to dispense glue, and weighing the glue dispensing quantity to obtain the current single glue dispensing quantity W.
Step S3, judging whether the current single glue outlet quantity W is within the range of the target glue weight parameter; if the glue weight parameter is within the target glue weight parameter range, performing glue dispensing operation; if the glue weight parameter is not in the range of the target glue weight parameter, the next step is carried out.
Further, if the current single glue outlet quantity W is within the target glue weight parameter range, the current glue outlet is stable and meets the requirements, and the glue dispensing valve moves from the weighing area to the glue dispensing area to perform glue dispensing operation.
S4, comparing the current single glue outlet quantity W with glue weight adjusting parameters to obtain a comparison result; wherein, the comparison result comprises: the current single glue outlet quantity W is between [ S ] max ，W H ]The interval and the current single glue outlet quantity W are between [ W ] L ，S min ]Within the interval.
And S5, according to the comparison result, the current valve opening time and the delay time are adjusted by combining the valve opening adjustment increment tk and the single glue outlet cycle time, the glue outlet amount of the dispensing valve is compensated, and the step S3 is returned after the compensation.
In this embodiment, the number of times of adjusting the current valve opening time and the delay time corresponds to the number of times of compensating the glue outlet amount of the dispensing valve, after each time of compensating the glue outlet amount of the dispensing valve, the glue outlet amount is also weighed, and if the glue weight is within the target glue weight parameter range, the glue outlet amount of the dispensing valve is successfully calibrated.
Such as: and the current valve opening time and the delay time are regulated for three times, correspondingly, the glue outlet quantity of the dispensing valve is compensated for three times respectively, the glue outlet quantity is weighed for three times respectively, and if the glue weight of each time is within the range of the target glue weight parameter, the calibration of the glue outlet quantity of the dispensing valve is successful, and the calibration precision is high.
In this embodiment, when the glue amount of the glue dispensing valve is actually calibrated, as long as the obtained glue weight is within the target glue weight parameter range, it is determined that the glue amount of the glue dispensing valve is successfully calibrated, so as to improve the calibration efficiency, therefore, when the glue amount of the glue dispensing valve is actually calibrated on site, the current valve opening time and the delay time are generally only required to be adjusted for 1 to 2 times, and the glue amount of the glue dispensing valve can be successfully calibrated by adjusting for at most three times, so that the calibration efficiency and the calibration precision are effectively improved.
Further, after the current valve opening time and the delay time are regulated for three times, if the glue weight is still not within the target glue weight parameter range, the fact that the glue quantity calibration of the glue dispensing valve is unsuccessful is judged, the glue dispensing machine gives an alarm, and a worker is reminded to check the glue dispensing valve.
In step S5, if the comparison result is that the current single glue output W is between [ S ] max ，W H ]In the interval, the valve opening adjustment increment tk is subtracted from the valve opening adjustment time, and the delay time is added with the delay adjustment increment TS; further, when the current valve opening time and the delay time are adjusted for multiple times, the current valve opening time is adjusted in a descending way, the current delay time is adjusted in an ascending way, for example, when the current valve opening time and the delay time are adjusted for three times, namely, when the current valve opening time is adjusted for the first time, the current valve opening time is T-tk, the current delay time is T+TS, when the current valve opening time is adjusted for the second time, the current valve opening time is T-2tk, the current delay time is T+2TS, when the current valve opening time is adjusted for the third time, the current valve opening time is T-3tk, and the current delay time is T+3TS. And the glue outlet amount of the glue dispensing valve is reduced through three times of adjustment, so that the glue outlet amount of the glue dispensing valve is in the range of the target glue weight parameter, and the automatic calibration of the glue outlet amount of the glue dispensing valve is realized.
If the comparison result shows that the current single glue outlet amount W is between [ W ] L ，S min ]In the interval, the valve opening time is regulated, the valve opening regulating increment tk is added, and the delay time is subtracted by the delay regulating increment TS. Further, when the current valve opening time and the delay time are adjusted for multiple times, the current valve opening time is adjusted incrementally, the current delay time is adjusted incrementally, for example, when the current valve opening time and the delay time are adjusted for three times, namely, when the current valve opening time is t+tk, the current delay time is T-TS, when the current valve opening time is t+2tk, the current delay time is T-2TS, and when the current valve opening time is adjusted for the third time, the current valve opening time is t+tkThe time is t+3tk, and the current delay time is T-3TS. Through three times of adjustment, the glue outlet amount of the glue dispensing valve is increased, so that the glue outlet amount of the glue dispensing valve is in the range of the target glue weight parameter, and the automatic calibration of the glue outlet amount of the glue dispensing valve is realized.
In the present embodiment, the current single glue output W is not within the glue weight adjustment parameter range [ W ] L ，W H ]And (3) if the glue dispensing machine is started to give an alarm, reminding a worker to check the glue dispensing valve.
In this embodiment, the calculation of the delay adjustment increment TS includes the steps of:
setting the valve opening time of the dispensing valve as T and the delay time as T;
calculating the glue outlet frequency of the glue outlet quantity before calibration: p1=1000/(t+t1+t2+t);
calculating the glue outlet frequency after calibration: p2=1000/(t+t1+tk+t2+t+ts);
let the glue outlet frequency of the glue outlet before calibration and the glue outlet frequency after calibration be the same, then:
1000/(t+t1+t2+T)=1000/(t+t1+tk+t2+T+TS)；
the delay adjustment increment ts= -tk is calculated,
wherein t1 is the rising time of the dispensing valve, and t2 is the falling time of the dispensing valve.
It should be noted that, according to the characteristic of the dispensing valve, as the valve opening time increases, the dispensing frequency will decrease, the dispensing point number in unit time will decrease, the decrease of the dispensing point number will affect the single dispensing amount, and further affect the effect of dispensing recalibration.

Further, as shown in fig. 3, the weighing assembly 23 includes: the weighing body 231 and the rubber cup 232, the weighing body 231 is provided with a weighing disc 2311, the rubber cup 232 and the weighing disc 2311 are both located in the sealing cover 22, the rubber cup 232 is arranged on the weighing disc 2311, and the rubber cup 232 is located right below the rubber inlet 221. When the dispensing valve is positioned right above the glue inlet 221, glue can be dripped into the glue cup 232 under the action of gravity, and then the glue amount of the time is weighed by the weighing disc 2311, so that whether the single-time outlet comparison amount of the dispensing valve meets the requirement is judged.
In this embodiment, the automatic calibration method for the glue dispensing valve glue amount is suitable for a full-automatic double-valve intelligent glue dispenser, and by calibrating before or at regular time of the glue dispensing operation, the single glue dispensing amount of each glue dispensing valve is kept at the required single glue dispensing amount, so that the problem that the stability and uniformity of the glue dispensing amount of the glue dispensing valve are difficult to ensure in the prior art when the glue dispensing valve works for a long time is avoided, the glue dispensing precision is high, and the glue dispensing amount is good.
