Description
Technical field
The present invention relates to a kind of tool of module street lamp lens, more particularly to one kind dissipate luminous intensity distribution entirety thoroughly for assembling
The tool of mirror and method.
Background technology
With electronic products such as LED illumination brightening product, MP4, MP5, digital camera, mobile phone and computers modern raw
Becoming increasingly popular in work, radiating and light decay as the LED post of illumination become the maximum bottleneck that LED uses.Use from us
The maturation of the technology of flip-chip packaged LED, and more and more it is applied to LED illumination product, because its structure is more and more small-sized
Change, the field of its application is also more and more extensive.In view of the particularity of integrated circuit package structure.But in street lamp assembling process
In, the mechanism of overall lenses is simple but assembling process is complicated, often results in the generation of defect, so that the lamppost surface of LED is pressed
Damage, lead to LED to have to scrap in the case that circuit structure and function are intact, cause serious waste.In order that
These LED are widely used in heat spreader module street lamp, and the defect in assembling process is maximum bottleneck.
Mostly street lamp the most frequently used at present is using integrated circuit plate, single lens hand assembled.Traditional hand assembled work
Skill efficiency is low, is not suitable for the reduction of cost.In addition with the continuous progress of LED encapsulation technology, the package dimension of LED is increasingly
Little, the gap between lamppost and lamppost is also less and less, and in unit area, the quantity of LED also gets more and more (as super-small
(4mm), minimum clearance (2mm), this allows for overall molding one-time formed lens and increasingly becoming necessary.Due to traditional hand
For aligning accuracy less demanding, (it is commonly used to big to package dimension (8mm or more) to work assembly technology, and lamppost spacing is big
The street lamp of (8mm or more) is with single lens), therefore using traditional hand assembled technique to small size Small Distance lamp now
Post module damages LED post by pressure ratio during being assembled is very high, and the success rate of assembling is low, traditional hand assembled technique
It is only used for analyzing the small lot assembling of experiment, it cannot meet the requirement of industrial mass production at all.
And by the cooperation of tool, packaging efficiency is directly enhanced using reflow soldering, and in order to realize producing in batches, can
Packaging technology is completed with the production line being considered as the automation for producing electronic circuit board.The main production of this production line
Equipment includes chip mounter and reflow soldering, is produced in batches it can be considered to the reflow soldering using this production line.
Because the production procedure of electronic circuit board is the circuit that lamppost is attached to swiped through tin cream and thermal grease conduction by chip mounter
On plate, then through reflow soldering, by lamppost reliably welding process in the circuit board.The temperature and time of its Reflow Soldering is to be based on
Come to adjust, whole reflux course is by warming up period, temperature raising period to the quantity of the thickness of plank and components and parts, flows back the phase, cooling phase
To complete whole welding job.The temperature of wherein warming up period is from the beginning of 60 degree, and the duration is in 20s；Again through excess temperature
The temperature raising period of 140 degree of degree, the duration is 1 point half about；Afterwards enter the backflow phase, its reflux temperature typically at 225 degree about,
Continue the time of 15s；Finally experiencing cooling phase, the temperature of wiring board being lowered, thus reliably lamppost is welded on plank
On.
If directly using die-filling piece of technique groups on this production line, can there is problem below in practical application：
1., because lamppost size only has 3mm, spacing also only has 2mm, quantity more than 100 during assembling, craft
Welding efficiency is extremely low.During assembling lens, lens are easily pressed onto lamppost, so that lamppost lens is easily dropped.
2. during assembling lens, lens are easily pressed onto lamppost, so that lamppost lens is easily dropped and crushed, due to reverse installation process
Particularity, fluorescent material and lamppost lens are integrally formed, and cause also to destroy phosphor powder layer while lens damages, thus
Cause the inefficacy of lamppost.
As can be seen here, the tool of above-mentioned existing module lens structure with use on it is clear that still suffered from inconvenient and scarce
Fall into, and be urgently further improved.Therefore how to found a kind of assembling of new structure and dissipate controlling of luminous intensity distribution overall lenses
Tool and method, also becoming current industry pole needs improved target.
