Specific embodiment
As shown in figures 1 to 6, including the frame 2 being set on mechanical arm 1, the frame 1 is equipped with Glue dripping head 3, institute to the present invention It states and is equipped with colloid 4 in Glue dripping head 3, the frame 2 is equipped with c-opening 20, and the opening 20 is backwards to mechanical arm 1, the opening Limiting device and buffer unit are equipped in 20, the limiting device is located at 20 inside of opening, and the buffer unit is located at opening 20 Outside, limiting device and buffer unit are all provided with and buffer unit interior in opening relative to limiting device closer in opening Portion,
The limiting device includes slide bar 41 and sliding block 42, and the slide bar 41 is fastened in opening 20, and the sliding block 42 is along slide bar 41 direction of extension are equipped with perforation 420, and the slide bar 41 is arranged in perforation 420, and the side of the sliding block 42 connects Glue dripping head 3; Sliding block does linear motion up and down on slide bar, due to being connected with the side of sliding block for Glue dripping head, so sliding block can drive dispensing Head moves up and down, and further, since sliding block can only do linear motion up and down on slide bar, limits the stroke of sliding block, also The stroke of the Glue dripping head of limitation avoids Glue dripping head from closely weighing chip wounded excessively with to chip for dispensing glue.
The buffer unit includes limited post 51, spring 52 and casing 53, and the limited post 51 is set to 20 medial roofs of opening Portion, the spring 52 are set on limited post 51, and the top of the spring 52 is movably connected in 20 top of opening, the spring 52 Bottom end be fixedly connected with casing 53, described sleeve pipe 53 is socketed on limited post 51, does linear motion up and down along limited post 51;
3 bottom of Glue dripping head is d relative to conplane difference in height with 53 bottom of original state setting of casing1, described sleeve pipe 53 range is d2, the d1And d2Relationship be:d1〉d2.In this way, casing is postponed limit during mechanical arm pushes Column moves upwards, and under the buffer function of spring, mechanical arm is effectively avoided to be hit power and damage, meanwhile, cannula tip movement To after highest point, between Glue dripping head bottom and chip still have certain distance, avoid Glue dripping head with it is excessively close to chip for dispensing glue And weigh chip wounded.
The bottom of described sleeve pipe 53 is equipped with rubber pad 530.In this way, delaying casing with the contact to dispensing chip Punching, avoids casing from excessively pushing and causes wafer damage.
The Glue dripping head 3 is including pen container 31 and in pen container 31 and extends to the syringe needle 32 outside pen container 31, the pen The bottom of cylinder 31 is equipped with through-hole 311, and the syringe needle 32 runs through the through-hole 311,
From edge to central reduction, tapered, the inside top of the pen container 31 is equipped with pressure spring 33, described for 31 bottom of pen container 33 connecting needle top of pressure spring;
It further include baffle 34, the baffle 34 is set in 32 lower part of syringe needle and is arranged in bottom in pen container 31;
The pen container 31 is provided with colloid 6.At work, mechanical arm drives Glue dripping head to move downward, and needle resists to be coated Place is smeared, is pushed, syringe needle is remain stationary, and pen container can move downward, and baffle is moved upwards relative to pen container, so that in baffle and pen container Gap is generated between wall, in this way, colloid is moved downward through gap under the effect of gravity, to be formed full of baffle and opening Cavity;It is equipped with pressure spring between pen container and syringe needle, starts energy storage in pressure spring, the descending motion of pen container is more steady, will not produce Raw too fast movement, in this way, operation is more stable, reliable, meanwhile, when starting dispensing, mechanical arm drives pen container to move upwards, Under the action of pressure spring elastic force, promote the rising of pen container, at this point, baffle is moved downward with respect to pen container, so that between baffle and opening Cavity become smaller, be open in this way, colloid will be extruded by baffle, syringe needle of postponing reaches frame, while but also glue in pen container Body keeps certain mobility;Pen container bottom is from edge to central reduction, tapered, and pen container consists of two parts, and a part is Straight-tube shape, a part are cone cells, in this way, just generating gap between meeting and pen container after baffle rises with respect to pen container, it is ensured that colloid can be with Outflow.
The syringe needle 32 is arranged equipped at least a pair of of plectrum 320, a pair of plectrum 320 in inverted V type, and several described groups Piece 320 is symmetrically set up, and the plectrum 320 is located in pen container 31.A pair of of plectrum is arranged in inverted V type, that is to say, that plectrum is towards pen Cylinder bottom angled, in this way, plectrum is moved downward with respect to pen container in pen container uphill process, plectrum squeezes colloid and moves downward, and promotees Into the discharge of colloid, meanwhile, up and down motion of the plectrum in pen container has stirred colloid, ensure that the mobility of colloid.
31 inner top of pen container is equipped with bearing 312, and the pressure spring 33 is located at the axial centre of bearing 312, the bearing Riffled tube 35 is arranged in 312, the riffled tube 35 is set on syringe needle 32, and the screw pitch of the riffled tube 35 is 7- The outer wall of 8mm, the riffled tube 35 are equipped with several stirring blades 350.In this way, driving riffled tube downward after pen container pushes Movement, since the screw pitch of riffled tube is larger, reached 7-8mm, so, syringe needle shore effect under, riffled tube starts Rotation, under the support of bearing block, the spinning movement of riffled tube is more smooth, and opposite pen container will not generate displacement;Interior spiral shell The outer wall of line pipe is equipped with stirring blade, and stirring blade is rotated with the rotation of riffled tube, in this way, making the glue in pen container Body is flipped, it is ensured that the mobility of colloid.
The stiffness factor of the pressure spring 33 is less than the stiffness factor of the spring 62.That is, pressure spring is relative to pressure spring It is more easier to be compressed or stretched, in this way, pen container is made to be more easier to be pressed, it is ensured that plastic emitting is reliable.
