Abstract
A chip branching device relates to a branching device of a copper particle pre-welding chip. The chip branching device is simple in structure and can be used for effectively reducing production costs and enhancing working efficiency. The device comprises an acrylic box, an acrylic box cover and a sucker; a groove is arranged on the surface of the acrylic box, the depth of the groove is larger than the thickness of the chip and less than the length and the width of the chip; the groove is protruded, an upper part with a small area is a discharging part, and a lower part with a large area is a chip accommodating part; the sucker comprises a sucker body and a bottom cover, a plurality of chip grooves are uniformly arranged on the front side of the sucker body, The back side of the sucker body is provided with a vacuum cavity, the vacuum cavity is sealed by the bottom cover; and the front side area of the sucker body is fitted with the small discharging part of the upper part of the acrylic box. By adopting the device, production efficiency is enhanced, product quality is guaranteed, and a demand of large batch production is satisfied.
Description
Technical field
The utility model relates to electronic applications, relates in particular to a kind of branching unit of shot copper prewelding chip.
Background technology
For the chip (particularly under the equally big situation of upper and lower shot copper) through the shot copper prewelding can not through direct with the aluminium alloy sucker reach branch to purpose, can only inhale one one in pen by hand and put in the mould respective aperture, this method is mainly not enough:
(1) technology falls behind: put with one one in traditional hand suction pen and produce, efficient is low, has increased working time, is difficult to produce in enormous quantities;
(2) of poor quality: one one in traditional-handwork suction pen is put, and product quality and employee's working experience, level of skill, qualification have confidential relation, and quality is differentiation with employee's difference;
(3) production cost is high: owing to adopt manual one one in the pen of inhaling to put that to carry out production efficiency low, the work period is long, has increased production cost, and yields is not high.
The utility model content
The utility model provides a kind of simple in structure, the chip branching unit that reduces production costs effectively, increases work efficiency to above problem.
The technical scheme of the utility model is: comprise acrylic box, acrylic lid and sucker;
Said acrylic box surface is provided with groove, and said depth of groove is greater than said chip thickness and less than the length and the width of chip; Said groove is convex shape, and the part that the top area is little is the output section, and the part that the bottom area is big is the ccontaining part of chip;
Said acrylic lid is a tabular, is detachably connected on the surface of said acrylic box upper groove, covers the big ccontaining part of chip of said groove bottom area;
Said sucker comprises sucker body and bottom, and the front of said sucker body is evenly equipped with the plurality of chips groove, and the back side of said sucker body is provided with vacuum chamber, and said bottom seals said vacuum chamber; The output section that the front face area of said sucker body and said acrylic box top area are little is suitable.
Said acrylic lid and sucker seal said groove after the short transverse butt joint.
Said chip homopolarity is located in the groove of said acrylic box to ground.
Said sucker front is provided with alignment pin, and the both sides of said acrylic box output section are provided with the location hole adaptive with said alignment pin.
Also comprise vacuum extractor and suction nozzle, said suction nozzle is communicated with the vacuum chamber of said sucker.
The chip that the chip branching unit of the utility model is good with prewelding forwards in the acrylic box in week, covers the acrylic lid, utilize the good chip height unanimity of prewelding in the acrylic box, can not stir to reach branch to purpose.Simultaneously, sucker is relied on the effect of alignment pin, covers on the acrylic box because the depth of groove of acrylic box makes chip move in the chip groove of sucker greater than chip thickness, less than the length and the width of chip through upset, the homopolarity that has guaranteed chip to.The utility model has improved production efficiency, has guaranteed product quality, satisfies the demand that product is produced in enormous quantities.

Embodiment
The utility model comprises acrylic box 3, acrylic lid 2 and sucker 1 shown in Fig. 1-8;
Said acrylic box 3 surfaces are provided with groove 32, and said groove 32 degree of depth are greater than said chip thickness and less than the length and the width of chip, make that said chip can only translation in groove 32, and can not overturn; Said groove 32 is convex shape, and the part that the top area is little is output section 321, and the part that the bottom area is big is the ccontaining part 322 of chip;
Said acrylic lid 2 is a tabular, is detachably connected on the surface of said acrylic box 3 upper grooves 32, covers the big ccontaining part 322 of chip of said groove 32 bottom areas; On acrylic lid 2 and acrylic box 3, be respectively equipped with corresponding location hole 1 and location hole 2 30, make both removably connect.
Said sucker comprises sucker body 1 and bottom 4, and the front of said sucker body 1 is evenly equipped with plurality of chips groove 12, and the back side of said sucker body 1 is provided with vacuum chamber 10, the said vacuum chamber 10 of said bottom 4 sealings; The output section 321 that the front face area of said sucker body 1 and said acrylic box 3 top areas are little is suitable.
