[0041] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0042] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0043] Firstly, such as Figures 1-2 As shown, this application provides a method for automatically adjusting the glue volume of a dispensing valve, including providing a dispensing machine, the dispensing machine including a dispensing valve, and the method for automatically adjusting the glue volume of the dispensing valve including the following steps:

[0044] Step S1: Set the initial parameters, standard weight parameters, and adjustment increment parameters of the dispensing valve;

[0045] Step S2: Dispense glue from the dispensing valve and weigh the amount dispensed;

[0046] Step S3: If the weighing is OK, start applying glue; if the weighing is NG, start the first weighing adjustment.

[0047] This includes: step S31, calculating the linear relationship constant between the current dispensing valve parameters and the dispensing volume as the K value;

[0048] Step S32: Adjust the current dispensing valve parameters to the T01 value according to the K value and standard weight parameters;

[0049] Step S33: Based on the T01 value, control the dispensing valve to weigh the dispensing material.

[0050] Step S4: If the weighing is OK, start dispensing glue; if the weighing is NG, trigger an alarm.

[0051] Step S5: After dispensing, begin the weighing countdown.

[0052] Step S6: When the countdown ends, weigh the glue. If the weight is OK, continue dispensing glue. If the weight is NG, proceed to the second weighing adjustment.

[0053] Step S7: Execute step S4.

[0054] In the embodiment, before the glue dispensing valve works normally, the glue dispensing valve is used to dispense glue once to weigh the glue, if the weight is within the preset range, the glue dispensing valve starts to work normally, if the weight exceeds the preset range, the glue dispensing valve starts to adjust the weight for the first time. It can be understood that the weight exceeding the range means that the current parameters of the glue dispensing valve and the wear degree of the glue pipe or the nozzle or the loss of the air pressure do not match. First, the current parameters of the glue dispensing valve are calculated, so that the parameters match the wear degree of the glue pipe or the nozzle or the loss of the air pressure (i.e. K value), so that the weight of the glue within the preset range, then according to the K value, the parameters of the glue dispensing valve are adjusted to T01 value, then the glue dispensing valve dispenses glue and weighs the glue, if the weight is within the preset range, the glue dispensing valve starts to work normally, if the weight is not within the preset range, the equipment alarms. After the glue dispensing is completed, the weighing countdown time, i.e. the next weighing time, is entered, after the countdown time is over, the glue dispensing valve dispenses glue and weighs the glue for the second time, if the weight is within the range, the glue dispensing valve continues to dispense glue, if the weight is not within the range, the glue dispensing valve starts to adjust the weight for the second time, after the adjustment, if the weight is within the range, the glue dispensing valve continues to dispense glue, if the weight is not within the range, the equipment alarms. The method and logical judgment scheme for automatically adjusting the glue amount in the actual production process saves the debugging time, solves the problem that the equipment needs to be frequently intervened by the workers in the production, and improves the automatic capacity of the equipment.

The average value of the remaining three weight values G2, G3 and G4 is G, which is calculated by removing one maximum value G5 and one minimum value G1 from the weight values. The average value of the parameters T2, T3 and T4 of the remaining three dispensing valves is T, which is calculated by removing one maximum value T5 and one minimum value T1 from the parameters of the five dispensing valves. The linear relationship constant K is obtained by dividing the average value of the weight T by the average value of the parameters of the dispensing valves G. The current dispensing valve parameter should be T01, which is obtained by dividing G by K.

The average value of the remaining three weight values G2, G3 and G4 is G, which is calculated by removing one maximum value G5 and one minimum value G1 from the weight values. The average value of the parameters T2, T3 and T4 of the remaining three dispensing valves is T, which is calculated by removing one maximum value T5 and one minimum value T1 from the parameters of the five dispensing valves. The linear relationship constant K is obtained by dividing the average value of the weight T by the average value of the parameters of the dispensing valves G. The current dispensing valve parameter should be T01, which is obtained by dividing G by K.

The average value of the remaining three weight values G2, G3 and G4 is G, which is calculated by removing one maximum value G5 and one minimum value G1 from the weight values. The average value of the parameters T2, T3 and T4 of the remaining three dispensing valves is T, which is calculated by removing one maximum value T5 and one minimum value T1 from the parameters of the five dispensing valves.
