A driving motor of the device can be conveniently and quickly replaced by a high-speed and high-precision motor with high torsion according to machining requirements; the driving motor is not directly connected with an injection cylinder; the electric liquid-dripping and dispensing device can be manually operated independently or is used with other production lines or automatic equipment such as a multi-axle numerically-controlled machine tool and a robot to precisely drip liquid stereoscopically; the device is totally driven mechanically; and a driving principle includes that the device is pushed by the motor, when receiving a driving signal, the motor drives a screw stem to rotate angularly according to the demand of the driving signal, the screw stem drives a nut to rotate, the nut pushes a piston push rod and a pushing piston to move axially, and finally liquid in the injection cylinder is extruded. In addition, when the injection cylinder is required to be replaced conveniently and quickly, a screw, which is used for fixing the nut, on a connecting plate and a screw on a mounting plate of the cylinder are manually screwed off by rotating, and the piston push rod, the pushing piston and the injection cylinder can be quickly replaced and arranged.

Description

Electronic dropping liquid and point glue equipment

Technical field

-the utility model is that a kind of electronic dropping liquid and point glue equipment are at a high speed and high-precision requirement and developing; No matter strength of fluid and viscosity height also can with at a high speed and high accuracy ooze. moreover; The device that the utility model relates to is automatic field and the basic Chu product that begins; Can independently be that equipment ground is used maybe can it be installed on the manipulator and operated with automated method. in addition; The utility model relates to the design of the architecture advances and the working method of dropping liquid and spot gluing equipment, can be adaptable across polytype commercial production and industrial automation field, for example:

-articles of dress: can accurately silica gel/pigment be oozed required shape clothing at clothes, handbag, waistband, and on the batching

-glasses and clock and watch: drip a diamond glue and a surface glue

-button: can high viscosity glue or pigment be oozed required accurate deal on button

- Circuit Board: Can accurate and high drop out Wuxi paddle

-electronics/household electrical appliances: edge sealing, fill

-industrial product

Background technology

In the industries such as electronic product manufacturing industry, articles of dress, watchmaking, often need dropping liquid and point glue equipment, some gluey fluids are expelled to working surface; Perhaps in some smaller gaps; The perhaps purpose in order to decorate will have the fluid of color, be expelled to and form some patterns on the workpiece.

Traditional dropping liquid and point glue equipment have an injection barrel that is used for carry fluid, and there is a discharging opening lower end of this barrel.Compressed air gets into the top of barrel through by-pass valve control, promotes the fluid in the barrel, and the discharging opening through the barrel lower end is expelled to surface of the work.

The method of work of tradition dropping liquid and point glue equipment is that control compressed air gets into the time of barrel, reaches beginning and the end of control fluid to the surface of the work injection.

The defective of prior art is:

1. be compressible, resilient owing to air, and fluid can not compress, constancy of volume.

Therefore the time of fluid injection beginning or end, lag behind the time that air pressure valve is opened or closed far away.

2. because the instability of compressed-air actuated operating pressure, and the variation of fluid viscosity, the speed of fluid injection also fluctuates.

3 When used in the field of automation, the pneumatic dispensing of non-Jiao Nong very stable.

The result of above-mentioned defective is, the injection precision of traditional dropping liquid and point glue equipment is lower, and injection speed is restricted.If full-bodied fluid, the more difficult control of injection precision, injection speed is more difficult to be improved, moreover it is just difficult to be applied in automation.

Summary of the invention

The technical problem that the utility model will solve is, in order to remedy the deficiency of above-mentioned prior art injection precision and injection speed, can precisely inject with the dropping liquid and the point glue equipment of high speed injection and can be applicable to automatic field and provide a kind of.

The utility model is to solve the technical problem the technical scheme that adopts to be: a kind of electronic dropping liquid and point glue equipment comprise: the bottom has discharging opening, is used to store the injection barrel of liquid; Be provided with in the injection barrel, act on the pushing piston of liquid in the barrel; Piston push rod that pushing piston top connects and drive piston be drive screw in axial sliding; Matching used nut and connecting plate thereof and slide block and rail plate thereof are installed in described screw rod and are connected on the pedestal; Nut is installed on the connecting plate; And connecting plate is installed on the slide block, and slide block is installed on the moving guide rail, and the axis of screw rod separates with the axis balance of barrel.

The axis of said in addition pushing piston and piston push rod separates with the axis balance of said drive screw, and screw rod can rotate with respect to piston and piston push rod.

When the rotating shaft of drive motors is rotated; Drive drive screw and produce screw, thereby screw rod can promote to produce screw in the hold-down nut, because of hold-down nut is installed on the connecting plate; And connecting plate is installed on the slide block; And slide block is installed on the guide rail, when drive screw rotates, just can promote pushing piston and piston push rod and in the injection barrel, axial displacement take place, and last liquid in barrel just can accurately be controlled and ooze.

The working method of this electronic dropping liquid and point glue equipment is: the rotating shaft of control drive motors; Rotate continuously or be interrupted and rotate or switching-over; Drive pushing piston indirectly through drive screw; With respect to upper and lower move of injection barrel and the fluid in the extruding injection barrel,, chase after and make fluid be expelled to surface of the work through the discharging opening of barrel lower end.

Compare with the dropping liquid and the point glue equipment of prior art, use the advantage of the utility model technical scheme to be:

1. drive motors drives pushing piston indirectly through drive screw, the fluid injection in the extruding injection barrel, and reaction speed is fast, does not adopt the hysteresis of compressed air extrusion fluid injection; The active force of pushing piston is bigger, and injection speed also can show and improves.

2. the rotational angle of control drive motors can accurately be controlled injection volume.

3. motor speed is more stable, and the pushing piston translational speed is constant, and the pressure of extrusion fluid is quite constant, and the flow velocity of fluid injection is even, is difficult for fluctuation.

4. improve the helical pitch of the moment of torsion or the reduction drive screw of drive motors, can be easy to the higher fluid of injection viscosity.

5. the continuous rotation through drive motors, be interrupted and rotate or switching-over, the conversion and the adjustment of speed of the motion of control pushing piston can realize several working ways, can satisfy the various accurate dropping liquid of different user various workpieces and put glue, put the needs of glue fast.

6. clean and change different size injection barrel for ease, pushing piston and piston push rod are indirectly by screw drive. like this can be fast with the injection barrel, and pushing piston and piston push rod remove or install.

7. dropping liquid of the utility model and point glue equipment are automatic field and the basic Chu product that begins. and this device can independently operate, and can be installed in to operate on the robot, also can combine other automation equipment and operates at production line.
