In the present embodiment, striker 7 is the micrometer head that can measure flexible restoring organ 8 decrement, micrometer head is arranged in the installation through hole on flexible magnifying arm 2, the axis vertical of this installation through hole is arranged, on flexible magnifying arm 2, threaded engagement is connected to three and stretches into and install through hole and be fixed the lock-screw of micrometer head, and reliable and stable for micrometer head can be fixed on flexible magnifying arm 2 by the pressuring action of lock-screw.And micrometer head installation site in installing through hole can be regulated by degree of tightness lock-screw, namely the setting height(from bottom) on flexible magnifying arm 2 can be regulated, and then can accurately control the moving displacement of nozzle needle 4.The decrement of flexible restoring organ 8 is accurately controlled so that the movement travel of nozzle needle 4 and speed are accurately adjustable by micrometer head.
The Electromagnetic Drive glue dispensing valve operation principle of the present embodiment and process are as follows: by selecting suitable pad 62 and a detachable bearing 13 so that flexible magnifying arm 2 level and and electric magnet 61 between gap length suitable；Adopting inner hexagon spanner turning adjusting screw 53, the decrement making coil tension spring 52 is suitable；Regulating striker 7 and install the installation site in through hole on flexible magnifying arm 2, make striker 7 to 8 one pre compressed magnitudes of flexible restoring organ, make nozzle needle 4 compress nozzle 3, the glue in glue cavity is full of glue passage under constant air pressure；When electric magnet 61 no power, nozzle needle 4 compresses nozzle 3, and glue can not flow out from nozzle 3.When electric magnet 61 is energized, electromagnetic attracting force armature 64 moves upward, armature 64 drive flexible magnifying arm 2 move upward compression coil tension spring 52, striker 7 with flexible magnifying arm 2 synchronize move upward, meanwhile flexible restoring organ 8 is replied.After flexible magnifying arm 2 moves upward to up stroke extreme position and keeps a period of time, electric magnet 61 power-off.Striker 7 moves downward under the spring force of flexible magnifying arm 2 hinge and coil tension spring 52 drives, striker 7 hits nozzle needle 4, nozzle needle 4 is made to overcome the active force of the resistance in passage and flexible restoring organ 8 to move downward, glue between nozzle needle 4 extruding jet nozzle 3 and glue chamber, forms partial high pressure, and glue sprays from nozzle bore rapidly, form small glue to drip, thus completing a course of injection, then electric magnet 61 continues energising, repeats said process.
The Electromagnetic Drive glue dispensing valve simple in construction of the present embodiment, be prone to accurate adjustment, response quickly, work frequency range on probation is wide, glue range of viscosities on probation is big, it is on-demand adjustable that it can realize the high frequency jet of big viscosity glue, adhesive liquid quantity and gelatin jet speed.
The electromagnetism glue dispensing valve of existing employing enlarger, its enlarger is directly connected with nozzle needle 4, and the movement travel of nozzle needle 4 and speed are equal to stroke and the speed of enlarger end.When the Electromagnetic Drive glue dispensing valve of the present embodiment works, energy variation is that electromagnetic force work done is converted into elastic potential energy and flexible hinge potential energy, then by the kinetic energy that potential energy is nozzle needle 4.Electromagnetic force work done is the product that electromagnetic force functions distance.Electromagnetic force is variable force, and the air gap appreciable impact electromagnetic force size between electric magnet 61 and the armature 64 being arranged on flexible magnifying arm 2, namely air gap is more big, and electromagnetic force is more little.When nozzle needle 4 needs relatively thin tail sheep, during bigger speed, the tradition electromagnetism glue dispensing valve moving displacement by travel limit enlarger, but electromagnetic force active force in long stroke is less, electromagnetic force work done is less, although the displacement being delivered on nozzle needle 4 is less, but nozzle needle 4 speed is only small, it is impossible to meet the injection of glue.Adopt the driving of separate type, reset mode, coil tension spring 52 and flexible magnifying arm 2 can be allowed to obtain potential energy (coil tension spring 52 rigidity and flexible magnifying arm 2 rigidity comparatively fully, compression distance and pendulum angle are known, this potential energy is determined, and adjustable), then potential energy passes to flexible restoring organ 8 and nozzle needle 4 by micrometer head collision, the moving displacement of nozzle needle 4 is determined by the compression displacement of flexible restoring organ 8, when compression displacement and flexible restoring organ 8 rigidity are only small, nozzle needle 4 still can obtain bigger speed, thus it is little to meet displacement, the kinetic characteristic that speed is big, and the concordance of nozzle needle 4 moving displacement is good, be conducive to steady operation.By adjustment stroke adjusting screw rod 54, micrometer head and flexible restoring organ 8, nozzle needle 4 can be made to obtain bigger velocity interval and larger displacement scope.And the driving of separate type, reset mode make the quality of nozzle needle 4 to reduce, it is possible to make its dynamic better.Therefore can in microelectronics equipment technology field, especially in the extensive use of microelectronics Packaging field.
Embodiment 2
The Electromagnetic Drive glue dispensing valve of the present embodiment is substantially the same manner as Example 1, the difference is that, replace stroke adjustment screw rod 54 with stroke micrometer head, be namely accurately controlled the angle of oscillation of flexible magnifying arm 2.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment.For those skilled in the art, obtained improvement and conversion also should be regarded as protection domain of the present utility model under without departing from this utility model technology concept thereof.
