Abstract

The utility model relates to a quantitative spot gluing machine, which comprises a compressed air source, a main compressed air pipeline, an auxiliary compressed air pipeline, an adhesive gun, and a timing controller, wherein, the main compressed air pipeline is provided with a pressure regulating valve, a pressure gauge, and a three-way valve in sequence. One end of the main compressed air pipeline is connected with a compressed air source, and the other end is connected with a hose. An air regulating valve and a branch pipe are arranged in the compressed air pipeline connected with the compressed air source in sequence and are communicated with atmospheric air to cause the pressure in the branch pipe to be negative pressure. In addition, a piston type adhesive gun causes viscose to be extruded out from a needle head by means of the propulsion of air pressure and the accurate control of the timing controller. The negative pressure simultaneously generates the resorption action to the viscose to cause the adhesive gun not to keep residual liquid.

Description

The quantitative point gum machine

This practicality newly relates to a kind of quantitative point gum machine, especially relates to a kind ofly residual phenomenon can not occurring when glue, and can make the some glue amount of each use keep stable quantitative point gum machine.

The mode of operation of quantitative point gum machine mainly is with quantitative mode plastic emitting, thereby reach the purpose of adhesion, can be applicable to the half-blank processing industry such as it, handicraft industry, computer peripheral industry such as motherboard, keyboard, mouse, telltale, chopping machine, scanner or the like.

In patent documentation, can find the point gum machine that some can cooperate above-mentioned application, for example No. 205180 Taiwan patent (control mechanism of quantitative discharging perfusion point gum machine) and No. 221116 Taiwan patent (the electric screw formula penetrates point gum machine automatically), last patent is to utilize Pneumatic pressure power to promote the viscose glue in the glue rifle and extrude viscose glue, and back one patent is to utilize spiral power to promote the viscose glue in the glue rifle and extrude viscose glue.Yet residual phenomenon in use all can appear in these two products of the prior art.Because general some glue operation is all extruded the point-like viscose glue with discontinuous in the glue rifle, thereby after extruding the point-like viscose glue by the glue rifle, though off switch or stop spiral, but the viscose glue in the glue rifle still has inertia force forward, make the syringe needle of glue rifle that residual phenomenon take place, thereby make each some glue quantitative change get less stable, and this residual phenomenon is very worried for the operator, it has not only influenced the fairness of operation, if it drips on the machined article, also will influence the quality of article, and this unsettled some glue amount can make that also the product texture of the article of processing is relatively poor.

In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model does not have residual phenomenon appearance after being to provide a kind of in use promptly each some glue, and each some glue amount keeps stable quantitative point gum machine.

To achieve these goals, the point gum machine in the utility model comprises a compressed air source, a main air pipeline, a secondary compressed air line, a glue rifle and a timing controller.Wherein, the upper end of main air pipeline is connected in compressed air source, is provided with pressure regulating valve, pressure gauge and triple valve in the path that it flows downward successively, is connected with a flexible pipe in its bottom at last.

The upper end of secondary compressed air line is connected in compressed air source, in the path that it flows downward, be provided with an Air-regulating valves and a branch pipe vertical successively with secondary compressed air line, the other end of this branch pipe is connected in the upper end of described triple valve, and the bottom of secondary compressed air line is communicated with atmosphere.

The glue rifle is a piston type glue rifle, comprises a tail-hood, a cylindrical shell and a syringe needle, and wherein tail-hood connects the other end of described flexible pipe, be filled with viscose glue in the cylindrical shell, simultaneously, cylinder body outer wall is provided with a PS (Push Switch), PS (Push Switch) by by electric wire and timing controller to be electrically connected.

Described timing controller is used for controlling the path of triple valve, promptly control triple valve make its be the L-R two ends connect or make its present-right two ends are connected, and can be set the L-R two ends length of turnon time.

Air-regulating valves in the secondary compressed air line is used to adjust the air supply that is disposed to atmosphere, so that produce suitable pressure corresponding to the viscose glue of different viscosities in branch pipe.

When using this quantitative point gum machine, at first set the schedule time length of timing controller, i.e. the time of the L-R two ends of triple valve connection, the pressure in the main air pipeline in its downstream is cut to a suitable pressure by pressure regulating valve.Then by the PS (Push Switch) of putting the glue rifle, then timing controller makes the L-R two ends of triple valve be communicated with, thereby pressurized air promotes the viscose glue motion in the glue rifle in the turnon time of this setting, makes viscose glue be released by point from the syringe needle of glue rifle.Timing controller makes triple valve L-R two ends close then, and on-connection of right two ends, the upper end of triple valve is connected in the branch pipe of secondary compressed air line at this moment, and the negative pressure in the branch pipe produces suitable resorption to the viscose glue in the glue rifle, therefore when glue, can not have residual phenomenon, and more stable some glue amount is arranged, thereby help improving the quality and the quality of processed product.

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described in further detail.

Fig. 1 is the structure configuration schematic diagram of the quantitative point gum machine in the utility model;

Fig. 2 is the glue rifle transparent view that part is cutd open in the utility model;

Fig. 3 is the transparent view of quantitative point gum machine one specific embodiment in the utility model.

As shown in Figure 1, the quantitative point gum machine in the utility model comprises a compressed air source 1, one main air pipeline 2, one secondary compressed air line 3, a timing controller 4 and a glue rifle 5.One end of main air pipeline 2 and secondary compressed air line 3 all is connected on the compressed air source 1.As shown in Figure 1, an end of main air pipeline 2 and secondary compressed air line 3 all is connected on the air supply pipe 11 of being drawn by compressed air source 1.Main air pipeline 2 is provided with pressure regulating valve 22, pressure gauge 23 and triple valve 24 successively in the path that it flows downward, and the other end of main air pipeline 2 is connected with a flexible pipe 6, and the other end of flexible pipe 6 is connected on the tail-hood 51 of glue rifle 5.Secondary compressed air line 3 is provided with Air-regulating valves 31 and a branch pipe 32 vertical with compressed air line 3 successively in the path that it flows downward, the other end of this branch pipe 32 is connected in the upper end A of triple valve 24, the other end of secondary compressed air line 32 is communicated with atmosphere, thereby makes that the pressure in the branch pipe 32 is negative pressure.When design, the length of branch pipe 32 should be lacked as much as possible, thereby makes that the negative pressure in the branch pipe 32 is the most obvious.

As shown in Figure 2, glue rifle 5 in the utility model comprises a tail-hood 51, a cylindrical shell 52 and a syringe needle 53, be provided with a piston 521 in its middle cylinder body 52, be filled with viscose glue 522 in the space under cylindrical shell 52 inner carriers 521, when air pressure promotes piston 521, viscose glue 522 is extruded from syringe needle 53.Cylindrical shell 52 outer walls of glue rifle 5 are provided with a PS (Push Switch) 54, PS (Push Switch) 54 by electric wire 55 and timing controller 4 to be electrically connected.Also can adopt simultaneously the piston type glue rifle of similar structures that sell the market or the glue rifle of more accurate complexity.
