Technical field
The present invention relates to a kind of nozzle in noncontact jetting point glue equipment, refer in particular to a kind of thin slice impacting type point glue nozzle.
Background technology
Point glue equipment is a kind of process equipment being widely used in production field.It is coated with from semiconductor packaging industry, IC industry, the welding of SMT/PCB assembly industry to general industry, note and seals, realized the Process of Applying Glue of the point, line, surface to colloid by this device.
In microelectronics Packaging industry, for adapting to the scrambling of workpiece, pursue high-quality, at high speed, high-precision fluid point glue equipment, dispensing technology the most gradually develops towards noncontact jetting point glue.
Nozzle is expensive as the core component of noncontact jetting point glue equipment, the formation to the injection of glue point, the size of glue point and quality important, and its manufacturing cost.
At present, noncontact jetting point glue equipment uses direct impinging injector (CN103464342A, CN103084299B, US20110300295A1 etc.), i.e. striker directly clashes into nozzle under the driving of external force and is sprayed by the glue between striker and nozzle, this mode is poor to full-bodied liquid jet ability, and the direct shock of striker and nozzle can cause nozzle heavy wear, substantially increasing the maintenance cost of noncontact jetting point glue equipment, these defects all limit being widely used of noncontact jetting point glue equipment.
Summary of the invention
Technical problem to be solved: for improving the nozzle performance for noncontact jetting point glue equipment, reduce its maintenance cost, the invention provides a kind of thin slice impacting type point glue nozzle, i.e. striker under external force drives is placed in the diaphragm above shower nozzle by shock, thin liquid between diaphragm compressing and shower nozzle produces high pressure, thus is sprayed by glue.
The present invention is realized in, a kind of thin slice impacting type point glue nozzle, including shower nozzle, spring thin slice, shower nozzle base, adjustment seat, enter cemented joint, striker, in nozzle set is loaded on the shoulder hole of shower nozzle base and be fitted to each other with positioning nozzle, adjustment seat and shower nozzle base by thread structure are connected with each other, adjustment seat is connected with each other by fine setting screw thread with entering cemented jointHitPin is placed in the centre bore of cemented joint, and spring thin slice is tightly pressed together by adjustment seat with shower nozzle, and forms thin liquid gap between the inner conical surface and the male cone (strobilus masculinus) of spring thin slice of shower nozzle.
It is evenly equipped with on described shower nozzle flange and connects thin liquid gap into glue groove, be provided with spray orifice at shower nozzle head, and communicate with thin liquid gap.
Described shower nozzle base is provided with the second glue annular groove and connects into glue groove, and adjustment seat is provided with glue feeding opening and connects the second glue annular groove.
Described spring thin slice is provided with annulus convex shoulder, and annulus convex shoulder and the lower surface entering cemented joint fit tightly, and can regulate the lower surface active force to annulus convex shoulder by fine setting screw thread, thus regulate the size in thin liquid gap.
Described enter cemented joint be provided with into glue passage and the first glue annular groove, enter glue passage and the first glue annular groove communicate, the first glue annular groove is identical with glue feeding opening.
Described enter glue passage connect with glue source, glue under pressure through enter glue passage, the first glue annular groove, glue feeding opening, the second glue annular groove, enter glue groove enter thin liquid gap form thin liquid layer.
Described striker and enter cemented joint and be arranged on point glue equipment, the up and down motion of striker is provided by point glue equipment, striker moves downward shock spring thin slice, spring thin slice acts on the thin liquid layer in thin liquid gap, the pressure moment making thin liquid layer increases, glue sprays from spray orifice, and spring thin slice the most quickly cuts off glue with shower nozzle laminating, eventually forms the injection of glue point.
Glue groove number of entering on described shower nozzle is 4 ~ 8, is evenly distributed on shower nozzle.
Described thin liquid gap is 0.08 ~ 0.2mm, can be by described fine setting threaded adjusting size.
Described spring thin slice has deformability under external force, and can return to original shape after external force is removed.
Beneficial effect: the striker of motion makes the pressure of thin liquid layer increase by clashing into spring diaphragm, spring diaphragm here serves the effect of hydraulic booster, the jet power of noncontact jetting point glue equipment can be effectively improved, the especially jet power to high viscosity glue, and spring diaphragm has completely cut off the shock of striker and nozzle, can effectively slow down the abrasion of nozzle, reduce the maintenance cost of noncontact jetting point glue equipment.
Accompanying drawing explanation
Fig. 1 is scheme of installation of the present invention；
Fig. 2 is the uniform schematic diagram entering glue groove 14 in the present invention on shower nozzle 1.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of thin slice impacting type point glue nozzle, including shower nozzle 1, spring thin slice 2, shower nozzle base 3, adjustment seat 4, enter cemented joint 5, striker 6, in shower nozzle 1 is set in the shoulder hole of shower nozzle base 3 and be fitted to each other with positioning nozzle, adjustment seat 4 and shower nozzle base 3 are connected with each other by helicitic texture, adjustment seat 4 is connected with each other by fine setting screw thread 8 with entering cemented joint 5, striker 6 is placed in the centre bore of cemented joint 5, spring thin slice 2 is tightly pressed together by adjustment seat 4 with shower nozzle 1, and forms thin liquid gap 15 between the inner conical surface and the male cone (strobilus masculinus) of spring thin slice 2 of shower nozzle 1.
