Description of drawings
Fig. 1 is the cutaway view of the utility model diaphragm type spray glue valve.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, the spray glue assembly of diaphragm type spray glue valve of the present utility model is made up of nozzle 2, striker 3, fixed cap 1 and two alignment pins 4.The sealing of nozzle 2 and striker 3 is accurate mated pair with the face of cylinder and the conical surface, and pairing is used, and can not exchange.There is spray orifice in nozzle 2 front end axle center, and diameter is between 0.1 millimeter～0.5 millimeter, can adapt to the needs of different colloids and different spray glue amounts.The spray orifice inwall is through specially treated, and is shaped, smooth, must not be jagged.Two alignment pins 4 securely are contained on the back plane of nozzle 2.When the connection of fixed cap 1 usefulness fine thread, when nozzle 2 was pressed on air chamber lower cover 5, the plane of two precisions closely contacted and guarantees that sealing, alignment pin 4 guarantee that again the glue passage that advances of two parts docks.
Air chamber component described in the utility model is made up of air chamber loam cake 13, air chamber lower cover 5, diaphragm 10, upper press ring 11, following pressure ring 8 and nut 12.Nut 12 is fixed on diaphragm 10 and upper and lower pressure ring 11 and 8 upper end of striker 3, four screws 9 are fixed on the outer ring of air chamber lower cover 5 and diaphragm 10 lower end of air chamber loam cake 13,5 of striker 3 and air chamber lower covers also have an O RunddichtringO 6, airtight air chamber around so just forming.Diaphragm 10 is folder cloth pressure-resistant rubber diaphragms of special manufacturing, stands ± 1.5 millimeters vibration at high speed that scope is interior millions of times.What the utility model adopted is the diaphragm of 0.5 millimeters thick.Compressed air can enter into the sealed gas chamber of diaphragm 10 belows from lower cover 5, compressed-air actuated expansive force can promote striker 3 by diaphragm 10, following pressure ring 11, upper press ring 8 and nut 12 and move upward, described diaphragm 10 is bulged by air pressure, just drives striker 3 and moves upward, and opens described nozzle 2.At this moment, the glue that advances the glue passage just can flow to nozzle and striker in the cavity that the lower end forms, for spray glue is got ready.
Reset assembly described in the utility model is made up of spring 15 and spring base 17.Adjustment assembly of the present utility model is made up of friction top 18, adjustment screw 20, calibration loop 16 and two O type circles 14 and 19.Spring 15 and spring base 17 are enclosed within the afterbody of striker 3.When the striker 3 of opening, rely on compressed spring 15 and spring base 17 to transmit elastic force striker 3 is moved downward rapidly, the glues in the nozzle 2 are sprayed from spray orifice, when the lower end of striker 3 conical surface knocks the inner conical surface of nozzle, the glued bundle of spray.Friction top 18 is screwed into air chamber loam cake 13 through fine thread, pressing spring 15, the pretightning force of adjustable reduction position spring.Adjustment screw 20 can transfer to spring base 0.2～3 mm clearance, and this gap is exactly the impulse stroke of striker 3, and calibration loop is fixed on the friction top 18, and calibration loop indicates the size of pretension elastic force, makes things convenient for the commissioning staff to operate.
Described in the utility modelly advance adhesive dispenser and be fingering cemented joint 7 and stretch out, connect sebific duct, barrel and rabbling mechanism again.Described inlet duct is meant inlet suction port 21 and stretches out, and connects air inlet pipe and electromagnetic gas valve again.
When the utility model used, two sides respectively established into glue and air inlet screw about the air chamber lower cover, wherein, glue feeding opening screw on into cemented joint, glue inlet tube, barrel and rabbling mechanism, composition advances adhesive dispenser.Air admission hole screw on inlet suction port, air inlet pipe and electromagnetic gas valve connect source of the gas, form inlet duct.The air inlet screw inwardly leads to the gap that forms between the gentle chamber of the following pressure ring lower cover of described diaphragm.Compressed air expands in this space, and the power of pressuring film plate just drives striker and moves upward.The gap is very little herein, remains between 0.4～0.8 millimeter.Very little cavity volume guarantees that air pressure produces enough power rapidly, and the motion of striker just takes place in moment.After the air chamber exhaust of below, reseat pressure presses striker to move downward rapidly, can make the glue in the nozzle produce high pressure, and glue just sprays from nozzle bore.
The utility model focuses on that spray glue valve is quick, the raising of sensitivity.Because the impulse stroke of spray glue valve is as short as in 0.2～3 millimeter, the reciprocating frequence height, the possibility of gas leakage is little, therefore piston type is changed into diaphragm type, and the O type circle that envelope gas is used changes into one from three.Simultaneously, the response speed to the control signal also must improve.On the other hand, at present the glue kind of packaged LED is various, for example silica gel, epoxy resin or the like, its range of viscosities from 100CPS to 20000CPS or more than, glue drip volume be low to moderate 0.1 little milliliter or below, and phosphor powder and other special additive have different viscosities and different hardness.Because the opening travel and the spring reset power of the utility model spray glue valve are adjustable respectively, therefore also more can adapt to the glue and the different glue amounts of ejection of different viscosities, the performance boost that makes the automatic glue-spraying machine is to new level.
