According to the packaged LED powder blending process, details and main points are strictly regulated in normative operation, hidden danger caused by misoperation is completely eradicated, manpower and automation are combined, production efficiency can be effectively guaranteed, precise powder blending and glue blending can be achieved in product quality, color temperature, the color rendering index and other key parameters are improved remarkably, and flaws, bubbles and other defective products can be completely eradicated.
Description
Technical field
The present invention relates to light emitting diode, especially a kind of packaged LED joins powder craft.
Background technology
LED invents in abroad, then just introduce China, really rising in China is in recent years, and the technique preparing a ring-encapsulation link in LED key is weaker, major part key technology rests in external large factory, in order to break technical monopoly, is necessary that the packaged LED developing a set of intellectual property of living alone joins powder craft, and packaged LED is joined powder craft and is mainly met the three large conditions such as normative operation, production efficiency and product quality, just can catch up with external advanced person and join powder technology.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of packaged LED and joining powder craft.
The technical solution used in the present invention is:
A kind of packaged LED joins powder craft: comprise the following steps: 1) cleaning glass cup, glass bar, powder spoon; 2) with powder spoon, a certain amount of fluorescent material is imported glass; 3) pour into and the A glue of fluorescent material amount with ratio by proportioning; 4) pour into and the B glue of A glue with ratio by AB glue proportioning; 5) fluorescent material in glass bar hand operated mixing glass and A, B glue uniformly fluorescent glue is utilized; 6) vacuum machine put into by glass, extracts the bubble in fluorescent glue out.
This packaged LED is joined powder craft and is also comprised step 7) and fall glue, and a hand-held syringe also allows it horizontal by 40-45 °, and the glass of the hand-held Sheng fluorescent glue of another is 120-130 ° by itself and syringe and slowly imports syringe, has led and has inserted stopper jam-pack to syringe entrance.
In described step 1), glass and glass bar adopt clean non-dust cloth wiping and blow away chip dust with air gun, use non-dust cloth wiping after the cleaning of powder spoon.
Described step 2), 3), 4) in fluorescent material, A glue, B glue adopt electronic scale to weigh and then count, and the precision controlling of fluorescent material amount is within 0.001 gram, and the precision controlling of A glue, B glue amount is within 0.05 gram.
When stirring in described step 5), glass and horizontal plane maintain an equal level, and glass bar againsts wall of cup and stirs in the shape of a spiral clockwise, and speed is 3-4 circle/second, duration 10 minutes.
Described glass bar need touch glass bottom when stirring.
After in described step 6), vacuum machine put into by glass, shut gate and vent valve, start power supply, operating personnel need watch the fluorescent glue in glass attentively, and bubble of emerging in fluorescent glue covers fluorescent glue gradually, when bubbles colloid will flow out from rim of a cup, open vent valve until clearly fluorescent glue can be seen, shut vent valve again, repeat above-mentionedly to open, close vent valve action until no longer include bubble and emerge, follow-up a period of time of vacuum again.
Beneficial effect of the present invention:
Packaged LED of the present invention joins powder craft strict regulations details and main points in normative operation, stop the hidden danger that maloperation brings, adopt and manually combine with automation, effectively can ensure production efficiency, in product quality, can realize accurately joining powder and join glue, the key parameter such as colour temperature, colour rendering index is significantly improved, also can stop the generation of the defective products such as flaw, bubble.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Fig. 1 is the flow chart that packaged LED of the present invention joins powder craft.
Detailed description of the invention
Be illustrated in figure 1 a kind of packaged LED of the present invention and join powder craft, a kind of packaged LED joins powder craft, comprises the following steps:
1) cleaning glass cup, glass bar, powder spoon, wherein, glass and glass bar adopt clean non-dust cloth wiping and blow away chip dust with air gun, use non-dust cloth wiping after the cleaning of powder spoon.
2) electronic scale fluorescent material weighs and then counts, and with powder spoon, a certain amount of fluorescent material is imported clean glass, and the precision controlling of fluorescent material amount is within 0.001 gram; For multiple fluorescent material, need according to first few rear many orders weighing, mixing.
3) pour into and the A glue of fluorescent material amount with ratio by proportioning, adopt electronic scale to weigh and then count, precision controlling is within 0.05 gram;
4) pour into and the B glue of A glue with ratio by AB glue proportioning, adopt electronic scale to weigh and then count, precision controlling is within 0.05 gram;
5) fluorescent material in glass bar hand operated mixing glass and A, B glue uniformly fluorescent glue is utilized; During stirring, glass and horizontal plane maintain an equal level, and glass bar againsts wall of cup and stirs in the shape of a spiral clockwise, and glass bar need touch glass, and low speed degree is 3-4 circle/second, duration 10 minutes, to ensure that fluorescent material and colloid can fully mix.
6) vacuum machine put into by glass, extracts the bubble in fluorescent glue out.After vacuum machine put into by glass, shut gate and vent valve, start power supply, operating personnel need watch the fluorescent glue in glass attentively, and bubble of emerging in fluorescent glue covers fluorescent glue gradually, when bubbles colloid will flow out from rim of a cup, open vent valve until clearly fluorescent glue can be seen, shut vent valve again, repeat above-mentionedly to open, close vent valve action until no longer include bubble and emerge, follow-up a period of time of vacuum again (being advisable with 5 minutes).；
