Description
Technical field
The utility model relates to a kind of IC of being applicable to manufacturing industry, especially is applicable on liquid crystal panel, the circuit board sealing rifle to the sealing of IC sheet.
Background technology
Existing sealing rifle generally is that hand control is advanced the glue valve, and when needs advanced glue, hand pinched into glue valve handle, opens the glue valve, goes into when allowing colloid in the sealing rifle, when not needing into glue, unclamps into glue valve handle, can close into glue valve.There is the problem of two aspects in this sealing rifle, the one, the glue valve is advanced in long-term manual control, be unsuitable for long-time operation, and often circuit board or liquid crystal panel have many IC points to need encapsulation, and on production line, the workpeople especially the woman worker for finishing the work, must all day mechanically repeatedly hand pinch into glue valve, at the end of the day, palm is pain very; This on the other hand sealing rifle also exists the colloid input uncontrollable, makes the terminal point coating widen and thicken, and influences the problem of product quality.
Chinese patent literature CN101032713 discloses a kind of point glue equipment, comprise the hydraulic valve needle device of a control glue material flow and the pneumaticpiston device of a control point glue speed, be provided with a needle in the valve body of described hydraulic valve needle device, this needle has a hollow duct and communicates with the needle tubing that the valve body below is connected; Above-mentioned needle has a throttling profile at least, and the glue material that a glue material supply port injects on the valve body enters hollow duct through this throttling profile; Described pneumaticpiston device provides the upper-lower interactive motion, when air pressure passes in and out, the open and close that above-mentioned needle is entered the glue material in valve body, and utilize the throttling profile of needle and hollow duct to control glue material flow, and with at least one switching speed of a set screw control valve needle device.This point glue equipment has solved second above-mentioned problem preferably, but, this point glue equipment is owing to adopted a needle, and colloid is to flow into structure in the point glue equipment by being located at restriction on the needle, like this, in case just have restriction and not contraposition of supply port (promptly supplying with the mouth of colloid) on the needle, the glue amount into of will occurring few or even can not advance the situation of glue, in addition, also there is complex structure in this point glue equipment, the problem of maintenance difficult.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above, provides to society that a kind of to advance solation smooth, and sealing rifle simple in structure, easy to use.
Another purpose of the present utility model provides a kind of rifle of sealing efficiently easy to maintenance.
The technical solution of the utility model is: design a kind of sealing rifle, comprise lower gun body and reciprocal air pump, described reciprocal air pump is positioned at the top of described lower gun body, in described lower gun body, be provided with appearance glue chamber, send Jiao Dao and glue-feeder, described appearance glue chamber communicates with sending Jiao Dao and glue-feeder respectively, in described appearance glue chamber, also be provided with the outer piston that is connected with the piston rod of reciprocal air pump, outer piston can be reciprocating in holding the glue chamber under the effect of reciprocal air pump, when outer piston is in bottom dead centre, outer piston is closed described glue-feeder fully, and colloid is pressed into send Jiao Dao; When outer piston was in top dead-centre, the described glue-feeder of outer piston complete opening, colloid flowed into and hold the glue chamber.
Top at described lower gun body also is provided with upper cutting gun, and described lower gun body and upper cutting gun are fastenedly connected, and described reciprocal air pump is positioned in the described upper cutting gun.
On the outer wall of described outer piston, be provided with the O RunddichtringO.
Piston top at reciprocal air pump is provided with back-moving spring.
Top at described upper cutting gun is provided with nut, is provided with the adjusting screw(rod) of the stroke that is used to regulate described reciprocal air pump on described nut.
The utility model has adopted and be provided with appearance glue chamber in described lower gun body, sent Jiao Dao and glue-feeder, described appearance glue chamber communicates with sending Jiao Dao and glue-feeder respectively, in described appearance glue chamber, also be provided with the outer piston that is connected with the piston rod of reciprocal air pump, outer piston can be in holding the glue chamber under the effect of reciprocal air pump reciprocating structure, like this, when outer piston moved downward, outer piston can be pressed into colloid on the one hand and send Jiao Dao, can stop up glue-feeder on the other hand; When outer piston moved upward, outer piston can allow glue-feeder open, and colloid flows into and holds the glue chamber.So, colloid does not need to enter in the rifle body after the glue-feeder contraposition again, thereby has guaranteed the fluency of colloid.
The utility model has also adopted on the top of described lower gun body and also has been provided with upper cutting gun, described lower gun body and upper cutting gun are fastenedly connected, and described reciprocal air pump is positioned at structure in the described upper cutting gun, like this, after reciprocal air pump breaks down (parts that the sealing rifle easily goes wrong most are exactly reciprocal air pump), only need upper cutting gun and lower gun body are separated (unclamping connecting screw rod gets final product), take out miniature reciprocal air pump, again change a micro air pump and get final product, have the advantage of convenient maintenance and replacement.
