Description
Technical field
The utility model relates to a kind of solid brilliant arm configuration of solid brilliant machine.
Background technology
Gu brilliant machine is a visual plant of producing light-emitting diode, its solid brilliant process comprises gets glue, puts glue, gets crystalline substance and puts crystalline substance, and chip automatic clamping and placing from the crystalline substance ring and is accurately placed to substrate, and solid brilliant quality is had decisive influence.And solid brilliant arm is exactly the mechanism that carries out this action, so very high to the requirement of solid brilliant arm.
Traditional solid brilliant arm is general to adopt following mode to produce:
Gu the material of brilliant arm is generally magnadure and processes; But because its strength of materials is prone to deform inadequately; Secondly along with the raising that the brightness of LED lamp, thermal stability, good heat dissipation etc. are required; Solid requirement to solid brilliant machine is also increasingly high. brilliantly confidentially ask solid brilliant arm will apply certain pressure to make chip and the substrate can firm being bonded together to chip, so requirement admittedly brilliant arm the on-deformable ability of intensity preferably will be arranged.
The utility model content
The technical problem that the utility model mainly solves provides a kind of new solid brilliant arm material, and this material can satisfy all functions of existing solid brilliant arm, and has improved the acceptance rate of solid brilliant product, has satisfied the market demand.
For solving the conventional art problem, the technical scheme that the utility model adopts is:
Gu brilliant arm; Comprise: some plastic pin, swing arm, contiguous block, spring base and swing arm seat, swing arm links to each other with contiguous block, and said some plastic pin is arranged on an end of swing arm; Spring base is arranged on the top of contiguous block; The swing arm seat is fixedly connected with contiguous block through screw, it is characterized in that, said swing arm, contiguous block, spring base and swing arm seat adopt carbon fibre material to process.
Wherein, below the junction of swing arm and contiguous block, be provided with two spring leafs and presser blade, and two spring leafs and presser blade fixed through screw.
Wherein, between said two spring leafs 0.25 ~ 0.3mm gap is arranged.
Wherein, respectively be provided with installing hole on said swing arm and the spring base, swing arm is fixedly connected through nut, spring and the screw that is connected successively with spring base.
Wherein, the opposite side of said swing arm is fixed with bolt, and screw is fixed on the said bolt through the through hole adjustable ground on the spring base.
The characteristics of the utility model are: the magnesium-aluminium alloy material that is different from the solid brilliant arm of prior art; Swing arm, contiguous block, spring base and the swing arm seat of the solid brilliant arm of the utility model all adopt carbon fibre material to process; Because this strength of materials is high; Advantage such as in light weight, not yielding, thus it is yielding to have overcome the solid brilliant arm of prior art, the defective that rigidity is not enough.

Embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.
Carbon fiber is claimed carbon fibre again, and the carbon fibre material carbon fiber material that is otherwise known as is made a general reference the material that some form with carbon fiber knit or MULTILAYER COMPOSITE, because it is not only light but also hard, so having many uses of it is general.Carbon fibre material and the contrast of other reinforcement materials have following characteristics:
(1) tensile strength: the tensile strength of carbon fiber is about 10 times of steel.
(2) modulus of elasticity: the tensile modulus of elasticity of carbon fibre composite is higher than steel, but the tensile modulus of elasticity of aramid fiber and glass fiber compound material then is merely a half-sum 1/4th of steel.
(3) fatigue strength: the fatigue strength of carbon fiber and aramid fiber reinforced composite is higher than high-strength guiding principle silk.Metal material is under the alternate stress effect, and fatigue limit is merely 30%～40% of quiet lotus intensity.Relax the crackle expansion because fiber and matrix are compound, and the possibility that has the reallocation of fiber internal force, the fatigue limit of composite material is higher, is about 70%～80% of quiet lotus intensity, and the significant sign of distortion is arranged before destruction.
(4) weight: be about 1/5th of steel.
(5) with the comparison of carbon fiber board: carbon fiber plate can stick on the body structure surface of different shape, and sheet material more is applicable to regular component surface.In addition, because the amount ratio sheet material of underfill resin layer is many when pasting sheet material, thickness is big, be not so good as sheet material with the adhesive strength of concrete interface.
See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, Gu brilliant arm comprises a plastic pin 1, swing arm 2, contiguous block 3, spring base 4 and swing arm seat 5; Swing arm 2 links to each other with contiguous block 3; Said some plastic pin 1 is arranged on an end of swing arm 2, and spring base 4 is arranged on the top of contiguous block 3, and swing arm seat 5 is fixedly connected with contiguous block 3 through screw; Said swing arm 2, contiguous block 3, spring base 4 and swing arm seat 5 adopt carbon fibre materials to process, and wherein carbon fibre material includes three kinds of polypropylene fibre, viscose and pitch fibers.Wherein, below the junction of swing arm 2 and contiguous block 3, be provided with spring leaf 7 and two presser blades 8, and through screw that spring leaf 7 and two presser blades 8 is fixing.Wherein, leave 0.25 ~ 0.3mm gap 81 between two presser blades 8.Because the wafer (not shown) of different size, the dynamics that some plastic pin 1 is drawn is different, and when dynamics was excessive, cushioning effect can be played in the gap 81 between this two presser blade 8, in case wafer is caused damage.Swing arm seat 5 is used to connect drive unit (not shown), thereby drive contiguous block 3 and swing arm 2 are moved up and down.
Wherein, said swing arm 2 is provided with installing hole 21, and swing arm 2 is fixedly connected through nut 42, spring 41 and the screw 23 that is connected successively with spring base 4.Come the compression degree of regulating spring 41 through adjusting nut 42, thereby control point plastic pin 1 is drawn the dynamics of different size wafer.
In the above-described embodiments, the side that swing arm 2 links to each other with contiguous block 3 is fixed with bolt 24, and screw 43 is fixed on the said bolt 24 through the through hole adjustable ground on the spring base 4, and then the position of scalable swing arm 2.
Be different from the magnesium-aluminium alloy material of the solid brilliant arm of prior art; Swing arm, contiguous block, spring base and the swing arm seat of the solid brilliant arm of the utility model all adopt carbon fibre material to process; Because this strength of materials is high; Advantage such as in light weight, not yielding, thus it is yielding to have overcome the solid brilliant arm of prior art, the defective that rigidity is not enough.This material can satisfy all functions of existing solid brilliant arm, has satisfied its requirement on solid brilliant arm greatly, and has improved the acceptance rate of solid brilliant product, and then high-speed, the high precision position requirement that improve solid brilliant machine.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
