Problems solved by technology

In terms of accuracy, it is difficult to guarantee the accuracy in the range of 0.5 mg due to the heavy labor intensity of operators
In terms of repeatability, due to the inconsistent operation level of each operator and the characteristics of various raw materials, there will be no reliability and repeatability in terms of repeatability
[0004] In addition, some raw materials have special hygroscopicity. In an open environment, they are very easy to absorb moisture and deteriorate, which has a certain impact on the quality of the finished ingredients.
And because the environment of manual operation cannot be sealed, when using hygroscopic raw materials, the quality of ingredients cannot be well guaranteed

Embodiment 1

[0089] Embodiment 1, as shown in the table below:

[0090]

[0091] A glue batching process, start the air compressor, so that the air pressure on the box reaches a stable value.

[0092]1) To set parameters, enter 10.0000g in the target weight column, 0.0030g 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.

[0093] 2), reset and clear the precision weighing instrument;

[0094] 3), start the switch, and the device starts to run;

[0095] 4) When the large rubber valve is discharged, the time from opening to closing of the first stage control solenoid valve is 150 milliseconds, and the touch screen displays a weight of 0.2000g;

[0096] The large rubber valve discharges the material, the second stage controls the solenoid valve opening to closing tim...

Embodiment 2

[0111] Embodiment 2: C powder discharging, as shown in the table below,

[0112]

[0113] C powder 12g, use point vibration conveying device, this 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 that the device operates, and its operation mode starts from the seventh stage to the end of the first paragraph.

[0114] 1) Set the parameters, the allowable error is 0.0030g, reset the precision weighing instrument, and start the device, as shown in the above table;

[0115] 2) In the seventh stage, the weight is set to 7.0000g, that is, when there is still 7.0000g of C powder left (actually 5.0000g of C powder has been collected in the container cup), switch to the sixth stage of operation;

[0116] 3) In the sixth stage, the set weight is 2.1000g, that is, when there is still 2.1000g of C powder left (9.9000g of C powder has actually been collected i...

Embodiment 3

[0119] Embodiment 3: as shown in the table below,

[0120]

[0121] F powder 18g, use the screw vibrating conveying device, this device relies on the joint operation of vibration and 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 clogging the pipeline, and use the precision weighing instrument to feedback The 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.

[0122] 1) Set the parameters, the allowable error is 0.0030g, reset the precision weighing instrument, and start the device, as shown in the above table;

[0123] 2) In the seventh stage, the weight is set to 4.0000g, that is, when there is still 4.0000gF powder left (actually 14.0000gF powder has been collected in the container cup), switch to the sixth stage;

[0124] 3) In the sixth stage, the set weight i...

Abstract

The invention discloses a LED gelatine powder precision automatic burdening method, the method can be realized through hardware and software, software is arranged in a PLC controller system, hardware comprises several powder feeding apparatus, several gelatin feeding apparatus and an air compressor, a container cup is arranged at lower part of a discharge hatch, a container cup is placed on a precision weighing instrument, the air compressor is connected to the gelatin feeding apparatus through a pipeline, the gelatin feeding apparatus can control a switch by a solenoid valve, a large gelatin valve and a small gelatin valve are arranged at a discharge end, the large gelatin valve and the small gelatin valve are connected to a solenoid valve respectively through a flexible pipe, the solenoid valve is connected to a PLC controller, the PLC controller can control switch of the solenoid valve according to weight feedback information weighed by the precision weighing instrument, the PLC controller can control the feeding speed, vibration frequency, motor rotating speed and operation voltage value of the powder feeding apparatus according to the weight feedback information weighed by the precision weighing instrument, and thereby precision ratio is reached.

Description

technical field [0001] The invention relates to the field of precision instruments, in particular to a precision automatic batching method for LED rubber powder, which can achieve high-precision ratios for various powders and liquids. Background technique [0002] In the fields of test analysis, trace element addition, fine chemical industry, etc., the accuracy of ingredients is required to be very high. Generally, it needs to reach ±10mg, and the requirement for higher occasions needs to reach ±0.5mg. [0003] At present, in the occasions where precise proportioning and high-precision ingredients are required, the manual proportioning method is basically adopted, and the accuracy and repeatability are determined manually by the operator. In terms of precision, it is difficult to guarantee the precision in the range of 0.5 mg due to the heavy repetitive labor intensity of operators. In terms of repeatability, due to the inconsistent operation level of each operator and the ...
