Description
Technical field
The utility model is related to LED die bond equipment, especially a kind of crystal-bonding adhesive point glue equipment.
Background technology
As shown in figure 1, existing LED die bonds point glue equipment includes cylinder 1, the dispensing platform 2 being arranged on cylinder 1 and is arranged on
Lug boss 3 on dispensing platform 2.Die bond Glue dripping head is put into viscose glue in lacquer disk(-sc) during die bond, then the Glue dripping head point after viscose glue exists
On the die bond region of substrate, Glue dripping head is contacted with substrate during due to dispensing, so that the crystal-bonding adhesive being bonded on Glue dripping head is outside
Overflow, so as to the uneven phenomenon of dispensing easily occur；In addition, after having put crystal-bonding adhesive, when lifting Glue dripping head and leaving substrate, due to
The contact area of Glue dripping head is big, and the glue of attachment is more and adhesive force is larger, and Glue dripping head can take away the glue amount of a part, finally lead
Cause the glue amount in die bond region on substrate less than normal, have a strong impact on the quality of follow-up die bond technique.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of crystal-bonding adhesive point glue equipment, reduces what is overflowed during dispensing
Glue amount, reduces the glue amount that Glue dripping head is taken away, it is ensured that die bond region has uniform enough glue amounts.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of crystal-bonding adhesive point glue equipment, including post
The first lug boss on body, the more than one dispensing platform being arranged on cylinder and setting dispensing platform；First lug boss
End face is provided with the second lug boss, the end area of the end area less than the first lug boss of second lug boss, the first lug boss
One end end face being connected with the second lug boss forms the side of flange, the flange and the second lug boss in the periphery of the first lug boss
Face forms and holds glue space.Utility model works principle：First lug boss and the second lug boss composition Glue dripping head, Glue dripping head is in glue
In disk after viscose glue, not only the end face in the second lug boss has glue, due to side and first lug boss of the second lug boss
Exist between flange and hold glue space, crystal-bonding adhesive can be stayed in appearance glue space, as supplement glue amount, so that the viscose glue amount of Glue dripping head
It is more；When the lower end millet cake of Glue dripping head is on substrate, only the second lug boss has part glue amount and overflows, due to the first projection
On glue amount effect is involved to the glue measurer being covered on the second lug boss so that the plastic emitting of Glue dripping head is evenly, and overflow
The glue amount for going out is smaller, it is ensured that die bond region has uniform enough glue amounts.
Used as improvement, first lug boss is cylinder or square body；Second lug boss is cylinder or square column
Body.
Used as improvement, the height of second lug boss is identical with for filling the lacquer disk(-sc) thickness of glue, it is ensured that the second lug boss
Surface is all coated with crystal-bonding adhesive.
Used as improvement, the dispensing platform is in array distribution, arrangement according to die bond region and sets on cylinder.
As improvement, the end area of the end area more than the first projection of the dispensing platform.
Used as improvement, the end area of first lug boss is S1, and the end area of the second lug boss is S2, S1=（1.5~3）
S2.First lug boss is relevant with the gel quantity of Glue dripping head with the end area relation of the second lug boss.
Used as improvement, one end of second lug boss is fixed on the centre position of the first raised end surface, and second is raised
The other end in portion forms mucilage glue surface.
The beneficial effect that the utility model is brought compared with prior art is：
Hold glue space due to existing between the side of the second lug boss and the flange of the first lug boss, crystal-bonding adhesive can stay in appearance
In glue space, as supplement glue amount, so that the viscose glue amount of Glue dripping head is more；When the lower end millet cake of Glue dripping head is on substrate,
Only the second lug boss has part glue amount and overflows, because the glue amount in the first projection is to the glue amount that is covered on the second lug boss
With effect is involved, so that the plastic emitting of Glue dripping head is evenly, and the glue amount overflowed is smaller, it is ensured that die bond region has uniform
With enough glue amounts.

Specific embodiment
With reference to Figure of description, the utility model is described in further detail.
As shown in Fig. 2 a kind of crystal-bonding adhesive point glue equipment, including cylinder 1, the more than one dispensing being arranged on cylinder 1
Platform 2, the lower surface for setting the first lug boss 4 on dispensing platform 2 and being arranged on the first lug boss 4 are provided with the second lug boss 6.Such as
Shown in Fig. 4, the dispensing platform 2 is in array distribution, its arrangement according to die bond region and designs, the present embodiment one on cylinder 1
Four dispensing platforms 2 are provided with altogether, and four die bond regions on counterpart substrate, partition grooves are additionally provided between adjacent die bond region respectively.
First lug boss 4 is cylinder 1 or square body 1, and second lug boss 6 is cylinder 1 or square body 1；It is attainable
Mode has：First lug boss 4 and the second lug boss 6 are cylinder 1；First lug boss 4 and the second lug boss 6 are square body
1；First lug boss 4 is cylinder 1, and the second lug boss 6 is square body 1；First lug boss 4 is square body 1, the second lug boss 6
It is cylinder 1 etc.；No matter which kind of mode, the end area of second lug boss 6 less than the first lug boss 4 end area, and institute
The end area of the end area more than the first projection of dispensing platform 2 is stated, whole Glue dripping head is in the trend being gradually reduced.Described first is raised
The end area in portion 4 is S1, and the end area of the second lug boss 6 is S2, S1=（1.5~3）S2；First lug boss 4 and the second lug boss 6
End area relation it is relevant with the gel quantity of Glue dripping head.The upper surface of second lug boss 6 is fixed on the lower end of the first lug boss 4
The centre position in face, the lower surface of the second lug boss 6 forms mucilage glue surface 61；First lug boss 4 be connected with the second lug boss 6 one
End end face forms flange 41 in the periphery of the first lug boss 4, and the side of the lug boss 6 of the flange 41 and second forms and holds glue space
5.The height of second lug boss 6 is identical with for filling the lacquer disk(-sc) thickness of glue, it is ensured that the surface of the second lug boss 6 is all coated with
Crystal-bonding adhesive.
Utility model works principle：First lug boss 4 and the composition Glue dripping head of the second lug boss 6, Glue dripping head is in lacquer disk(-sc)
After viscose glue, not only the end face in the second lug boss 6 has glue, as shown in figure 3, due to the side and first of the second lug boss 6
Exist between the flange 41 of lug boss 4 and hold glue space 5, crystal-bonding adhesive 7 can be stayed in appearance glue space 5, as supplement glue amount, so that
The viscose glue amount of Glue dripping head is more；When the lower end millet cake of Glue dripping head is on substrate, only the second lug boss 6 has part glue amount and overflows
Go out, because the glue amount in the first projection involves effect to the glue measurer being covered on the second lug boss 6, so that Glue dripping head
Evenly, and the glue amount overflowed is smaller for plastic emitting, it is ensured that die bond region has uniform and enough glue amounts.
