Embodiment 1
[0028] Embodiment 1: as shown in the table below
[0029]
[0030] According to the A glue batching process, start the air compressor to make the air pressure on the box reach a stable value.
[0031] 1) To set parameters, enter 10.0000 grams in the target weight column, 0.0030 grams in the error value column, and 150 milliseconds in the blanking time. The blanking time is the stable value selected in the test stage, that is, 150 milliseconds is the electromagnetic Once the valve is switched on and off, the weight value of glue A is relatively stable.
[0032] 2), reset and clear the precision weighing instrument;
[0033] 3), start the switch, and the device starts to run;
[0034] 4) When the large rubber plug is discharged, the time from opening to closing of the first stage control solenoid valve is 150 milliseconds, and the weight displayed on the touch screen is 0.2000 grams;
[0035] The large rubber plug is discharged, the second stage controls the solenoid valve o...
Embodiment 2
[0043] Embodiment 2: as shown in the table below,
[0044]
[0045] C powder 12 grams, using point vibration conveying device, the device is to make C powder fall into the container cup by vibration, and use the weight information fed back by the precision weighing instrument to switch the number of stages of the device, and its operation mode is from the seventh stage Beginning to the end of the first paragraph.
[0046] 1) Set the parameters, the allowable error is 0.0030 grams, reset the precision weighing instrument, and start the device, as shown in the above table;
[0047] 2) In the seventh stage, the weight is set to 7.0000 grams, that is, when there is still 7.0000 grams of C powder left (actually 5.0000 grams of C powder has been collected in the container cup), switch to the sixth stage of operation;
[0048] 3) In the sixth stage, the set weight is 2.1000 grams, that is, when there is still 2.1000 grams of C powder left (9.9000 grams of C powder has actually be...
Embodiment 3
[0051] Embodiment 3: as shown in the table below,
[0052]
[0053] F powder 18g, use the screw vibrating conveying device, this device relies on the joint operation of the vibration and the screw to make the F powder fall into the container cup, the screw is in the conveying pipeline, which can prevent the powder on the pipeline from blocking the pipeline, and use a precision weighing instrument Feedback weight information, the number of segments that the switching device operates, and its operation mode is from the seventh segment to the end of the first segment.
[0054] 1) Set the parameters, the allowable error is 0.0030 grams, reset the precision weighing instrument, and start the device, as shown in the above table;
[0055] 2) In the seventh stage, the weight is set to 4.0000 grams, that is, when there is still 4.0000 grams of F powder left (actually 14.0000 grams of F powder has been collected in the container cup), switch to the sixth stage of operation;
[0056]...
