Problems solved by technology

[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

[0028] Embodiment 1: According to the batching process of glue A shown in the table below, start the air compressor to make the air pressure gauge on the box reach a stable value.

[0029] 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.

[0030] 2) Reset and clear the precision weighing instrument;

[0031] 3) Start the switch, and the device starts to run;

[0032] 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;

[0033] The large rubber plug is discharged, the second stage controls the solenoid valve opening to closing ...

Embodiment 2

[0041] Embodiment 2: as shown in the table below, 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.

[0042] 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;

[0043] 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;

[0044] 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 been collected in the ...

Embodiment 3

[0047] Embodiment 3: as shown in the table below,

[0048] 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.

[0049] 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;

[0050] 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;

[0051] 3) In the...

Abstract

The invention discloses glue and powder automatic proportioning equipment for LED packaging. The equipment is provided with a PLC, and solenoid valves, point vibration conveying apparatuses, a screw vibration conveying apparatus and a heat energy drying device, which are connected to and controlled by the PLC controller. Discharge ports of the apparatuses concentrate together; a container cup is arranged below the discharge ports; the container cup is arranged on a precise weighing instrument; solenoid valves are connected to an air compressor through gas pipes; the PLC is connected to the precise weighing instrument, and the weight displayed by the precise weighing instrument is fed back to the PLC; and the PLC receives information and controls the on / off of the solenoid valves, vibration frequency and operation voltage and switching of each operation stage of the screw vibration conveying apparatus, vibration frequency, operation voltage, rotating speed of the motor and switching of each operation stage of the point vibration conveying apparatuses, so as to realize automatic proportioning of glue and powder.

Description

technical field [0001] The invention relates to the field of precision instruments, in particular to an automatic proportioning device for glue and powder for LED packaging. Background technique [0002] In the fields of test analysis, trace element addition, fine chemical industry and LED, 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 ±0.1mg. [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 0.1 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 characteristics of various raw materials, there will ...
