The glue dropping valve comprises a cylinder, a spray nozzle, a spray nozzle locking sleeve, a firing pin, an air inlet, a piston, an adjusting knob, a return spring and a glue inlet opening, wherein the spray nozzle is connected to one end of the cylinder through the spray nozzle locking sleeve; the firing pin is connected with the inner cavity of the spray nozzle and the cylinder cavity of the cylinder; the air inlet is connected with the cylinder cavity of the cylinder from the exterior of the cylinder; the piston is arranged in the cylinder cavity of the cylinder, and is connected with one end of the firing pin arranged in the cylinder cavity of the cylinder; the adjusting knob is arranged at the other end of the cylinder; and the return spring is arranged between the adjusting knob and the piston. The glue dropping valve is characterized in that the glue inlet opening is a through hole which is formed on the side wall of the spray nozzle and used for connecting the inner cavity of the spray nozzle with the external world. The utility model has the advantages that the travel of glue body from a charging barrel to the spray nozzle is shortened; the glue body is uniformly heated; the requirements of high speed jet can be met; the glue dropping quality is improved; the amounted of components is reduced; the processing cost is reduced; and the processing technology is simplified.
Description
Technical field
The utility model is mainly concerned with and is applied to the LED semicon industry, and fluids such as SMT paster industry control field specifically is meant at paster process mid-point glue and operates used injection apparatus.
Background technology
At present, the mode of paster or electronic component being carried out a glue mainly is a contact point glue, in a glue operating process, the syringe needle of plastic emitting must contact with quilt point paster or element, easy mobile paster or element in the process of contact, even occur easily paster or element be bonded on the syringe needle and take up, and the point glue equipment employing is that simple pneumatic promotion colloid is extruded, gel quantity to syringe needle is wayward, gel quantity too much or very fewly all can exert an influence to pasting effect, and have a strong impact on operating efficiency.Nowadays, though, someone has proposed some injecting type glue dispensing valves, for example: the patent No.: ZL 200720118722.2, the patent No.: ZL 200720171141.5, the patent No.: ZL200820096113.6, these three Chinese utility model patents have solved the problems referred to above, but these three kinds of patents all have a common defective, be exactly glue-feeder and nozzle be not on a part, but the inlet of glue-feeder is located on the sidewall of cylinder, by pipeline arrive with the nozzle joint face on, the one section pipeline of establishing again of nozzle docks with pipeline on the cylinder, complex structure, the stroke of colloid process is long, and it is minimum to cross the glue hole, make the process gummosis of colloid from the barrel to the nozzle chamber not smooth, the colloid heating is inhomogeneous, is fast in a glue speed by it, when flow is big, the heating uniformity of colloid is poor, some glue difficult quality guarantee.
Summary of the invention
In sum, main purpose of the present utility model is not enough at the glue-feeder design of existing injecting type glue dispensing valve, and a kind of injecting type glue dispensing valve that proposes.
The technical scheme that adopts for real the purpose of this utility model is: a kind of injecting type glue dispensing valve, comprise: cylinder, nozzle, nozzle lock sleeve, striker, air inlet, piston, adjusting turn-knob, back-moving spring and glue-feeder, described nozzle lock sleeve are connected nozzle at one end of cylinder; Described air inlet is connected with the cylinder chamber of cylinder from outside; Described striker connects the inner chamber of nozzle and the cylinder chamber of cylinder; Described piston places in the cylinder chamber of cylinder, and connects an end of striker in the cylinder chamber that places cylinder; Described adjusting turn-knob is located at the cylinder other end, is provided with back-moving spring with piston space regulating turn-knob, and described glue-feeder is the through hole that connects nozzle chamber and outside on the sidewall that is located at nozzle.
As being to the further improved technical scheme of the utility model:
Position corresponding with glue-feeder on the internal chamber wall of described nozzle is provided with annular groove.
Be connected with one in the described glue-feeder and advance cemented joint, described to advance cemented joint be dismountable being threaded with glue-feeder.
The center of described adjusting turn-knob also is provided with a fine setting turn-knob.
The beneficial effects of the utility model are: the utility model is located at glue-feeder on the sidewall of nozzle, directly supply glue for nozzle, flowing to the colloid that comes from barrel was stored in the annular groove on the internal chamber wall of nozzle before this, because outer periphery has heater, colloid can directly be heated once entering nozzle, shortened the stroke of colloid from the barrel to the nozzle, make the colloid homogeneous heating, satisfy the demand of high velocity jet, improve some colloid amount, all reduce on the number of components and parts, cut down finished cost, simplified processing process.In addition, the elastic force that the fine setting turn-knob can the fine adjustments back-moving spring, thereby control piston stroke and jet power, the effect that makes injection is more evenly suitably.
