Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In the hot-melt dispensing system, the temperature in the glue barrel is relatively high, and the glue barrel is in a closed state, so that the residual quantity of the liquid cannot be measured by installing a liquid measuring device. I.e. the amount of glue remaining cannot be detected by conventional photo-electricity and ultrasound. And glue the bucket and usually be metal construction, can't obtain the glue surplus in gluing the bucket through the mode of range finding. Thus, the acquisition of the residual amount of glue brings about corresponding troubles.
Referring to fig. 1 and fig. 6, fig. 1 is a flowchart illustrating an embodiment of a method for measuring a liquid level of a dispensing system according to an embodiment of the present invention, and for convenience of description, only portions related to the embodiment of the present invention are shown. The liquid level measuring method of the dispensing system specifically comprises the following steps:
S1O1, setting glue supply pressure and detection pressure;
s102, controlling a dispensing valve to start dispensing according to the set dispensing pressure and simultaneously starting timing;
s103, detecting that the pressure of the air pressure channel reaches a set value, and stopping timing;
s104, recording the set pressure time delta T when the pressure reaches a set value during dispensing;
and S105, acquiring the residual amount of the liquid in the glue barrel according to the set pressure time delta T.
Specifically, before the air pressure dispensing system starts to supply glue, the glue supply pressure and the detection pressure are set through the step S101; in the glue supplying process, the glue supplying pressure is the air pressure during glue supplying. The air pressure is transmitted to the glue barrel through a transmission pipeline so as to drive the glue barrel to output glue. After the set glue supply pressure and the detection pressure are set, in step S102, the glue dispensing valve is controlled to start glue dispensing according to the set glue supply pressure, and timing is started at the same time; the volume of the glue barrel is relatively large because the air pressure reaches the glue barrel through the transmission pipeline. When the glue barrel is used for discharging glue, a corresponding space is left. When the space is larger, the air pressure needs to be filled for a longer time to reach the detection pressure value. The time to reach the detection value due to the space being inflated is proportional to the size of the space. Therefore, the corresponding space size relationship can be obtained by detecting the length of time for the air pressure to reach the detection pressure value. After the time counting is started, in step S103, the pressure of the air pressure channel is detected to reach a set value, and the time counting is stopped; the pressure detector is communicated with the air pressure transmission channel to obtain the air pressure value of the transmission channel in real time and transmit the air pressure value to the controller, and when the pressure of the detected air pressure channel reaches a set value, the timing module of the controller stops timing. And in step S104, recording the time delta T when the pressure reaches the set pressure of the set value during dispensing; the time is the time from the beginning of the air conveying device to the beginning of the air inflation of the glue barrel through the conveying channel by the set glue supply pressure until the glue barrel reaches the set detection pressure. After acquiring the set pressure time Δ T when the pressure reaches the set value, in step S105, the remaining amount of the liquid in the glue bucket is acquired according to the set pressure time Δ T. The free space of the glue barrel is in proportional relation with the set pressure time Delta T. In an embodiment of the present invention, the method for obtaining the remaining amount of liquid of the glue barrel according to the time Δ T comprises: the residual ratio Vx is the slope parameter of the full volume-delta T of the dispensing barrel. The slope parameter is a known value corresponding to the size of the glue barrel, so that the residual amount of the liquid in the glue barrel can be obtained by setting the pressure time delta T.
The liquid level measuring method of the dispensing system provided by the embodiment of the invention comprises the following steps: S1O1, setting glue supply pressure and detection pressure; s102, controlling a dispensing valve to start dispensing according to the set dispensing pressure and simultaneously starting timing; s103, detecting that the pressure of the air pressure channel reaches a set value, and stopping timing; s104, recording the set pressure time delta T when the pressure reaches a set value during dispensing; and S105, acquiring the residual amount of the liquid in the glue barrel according to the set pressure time delta T. The glue bucket residual glue amount is calculated by capturing the time when the pressure of glue dispensing starts to reach, and the problem that the residual glue amount cannot be detected by using photoelectricity and ultrasonic waves due to metal sealing and high temperature of the hot drying glue bucket is solved. In one embodiment of the invention, the glue barrel is a hot melt glue barrel.
Referring to fig. 2, the method for obtaining the slope parameter includes:
s1051, setting glue supply pressure and detection pressure under the condition of filling a glue barrel;
s1052, controlling a dispensing valve to start dispensing according to the set dispensing pressure and simultaneously starting timing;
s1053, detecting the pressure of the air pressure channel to reach a set value, and stopping timing;
s1054, recording the pressure time Tmin of the set full-glue barrel when the full-glue barrel is full, wherein the pressure reaches the set value;
s1055, setting glue supply pressure and detection pressure under the condition of an empty glue barrel;
s1056, controlling a dispensing valve to start dispensing according to the set glue supply pressure and simultaneously timing;
and S1057, recording the pressure time Tmax of the empty glue barrel when the pressure reaches the set value.
S1058, calculating a slope parameter tan (a) ═ glue dispensing barrel full capacity/(Tmax-Tmin); and the Tmax is the pressure reaching set value of the air pressure detection channel when the glue barrel is empty.
Specifically, the size of the glue barrel is proportional to the time delta T for the air pressure to reach the set value. The proportional relationship is a slope parameter. The slope parameter can be obtained by measurement under the condition that the free space of the glue barrel is known. In one embodiment of the present invention, the slope parameter is measured and obtained under the condition that the glue barrel is respectively selected to be full of glue and empty. It should be noted that in some other embodiments of the present invention, the slope parameter can also be measured with glue barrels of 1/2 glue, 2/3 glue, and the like. When the glue barrel is in a glue full state, setting glue supply pressure and detection pressure under the condition of the glue barrel full through the step S1051; the glue supply pressure and the detection pressure are the same as the set values in the normal glue dispensing process. After the glue supply pressure and the detection pressure are set, glue dispensing is started according to the set glue supply pressure through the step S1052 and the glue dispensing valve, and timing is started at the same time; the atmospheric pressure passes through transmission path and exports gluey bucket, because the increase of tolerance leads to transmission path's atmospheric pressure increase, through pressure detector, can acquire the atmospheric pressure value on the atmospheric pressure transmission path in real time. In step S1053, the pressure in the air pressure channel is detected to reach a set value, and the timing is stopped; because the inflation time is relatively short when the glue barrel is full of glue, the set detection pressure value can be reached, and the pressure reaches the set full glue barrel pressure time Tmin of the set value when the glue barrel is full through the step S1054. The same procedure as the measurement when the glue barrel is full. And S1055-S1057, under the condition of the empty rubber barrel, the inflation time is relatively long, and the pressure reaches the set pressure time Tmax of the empty rubber barrel of the set value. It should be noted that, under the condition of the full glue bucket and the empty glue bucket, in order to ensure the accuracy of the measurement, the dispensing head may be operated in a manner of not discharging glue, and only the controller controls the opening of the dispensing valve on the air flow channel, and outputs the input gas to the glue bucket according to the set air pressure, so as to obtain the pressure time Tmin of the full glue bucket and the pressure time Tmax of the empty glue bucket. After the pressure time Tmin of the full glue bucket and the pressure time Tmax of the empty glue bucket are acquired, in step S1058, a slope parameter tan (a) ═ dispensing bucket full capacity/(Tmax-Tmin) is calculated. Fig. 7 is a slope diagram of one embodiment of a fluid level measuring system of a dispensing system of the present invention, as shown in fig. 7.
