Description
Technical field
The utility model relates to a kind of AB glue point glue equipment.
Background technology
AB glue is meant with A agent, two kinds of independent mode separate storage of B agent, during use A agent, B agent mixed by static mixing tube to scale or other modes are mixed and carried out bonding glue afterwards, the bi-component of being called solid or bi-component glue etc. are also arranged, be referred to as AB glue here.With glue from storage vat by method point of arrival needle heads such as force feeds, middle by control device control point needle head plastic emitting such as glue dispensing valve with stop plastic emitting, glue is the process that point-like or wire or large tracts of land shape be distributed on the bonding part of needs is called a glue.In filling, can industries such as assembling industry such as computer, mobile phone and capacitor, LED, need a plurality of independently parts by glue bonding or encapsulation get up.For the operation of AB glue point glue, because of existing glue control difficulty, to clean complicatedly, AB glue mixed proportion instability is put the colloid system complexity, problems such as troublesome maintenance, for a long time, the dispensing method of AB glue is perplexing these industries always.
The dispensing method of most of in the past AB glue comprises following two kinds:
Method 1: show as Fig. 1, the A agent of AB glue is delivered to AB coordinated type AB glue point glue equipment 1 by gear pump A, B agent respectively by gear pump B, AB coordinated type AB glue point glue equipment 1 is the integral body that comprises A agent glue dispensing valve 13, B agent glue dispensing valve 14 and cylinder manifold 15, the A agent enters A agent glue dispensing valve, the B agent enters B agent glue dispensing valve, A agent and B agent enter cylinder manifold 15 after the control by glue dispensing valve respectively, mix through entering static mixing tube 11 simultaneously behind the cylinder manifold 15, direct again inlet point needle head 12 carried out a glue after static mixing tube mixed.In order to guarantee the fixed proportion of A agent B agent, A agent glue dispensing valve and B agent glue dispensing valve are moved simultaneously, wherein arbitrary valve glue dispensing valve is out of order, and all will cause AB glue ratio out of control, has serious consequences.This point glue equipment complex structure, thus such shortcoming brought: 1) break down easily; 2) cost height can not be changed as running stores after the fault; 3) fixed proportion of glue can not guarantee conscientiously; 4) the maintenance complexity of glue dispensing valve; 5) when not using, clean difficulty; 6), can't connect and can't use this method with glue dispensing valve because plastic emitting is young for the fixedly encapsulation glue of 50ml class.
Method 2: show as Fig. 2, the push rod 24 that cylinder driving AB glue point glue equipment 2 directly drives with cylinder 23 pushes away the piston 26 of AB glue fixed sealing tubulature 25, make A agent and B agent enter the static mixing tube 21 that is installed in AB glue fixed sealing tubulature gum outlet, carry out a glue through the direct inlet point needle head 22 of the mixed glue of static mixing tube by fixed proportion.This method does not have glue dispensing valve to control the glue break-make, close glue and be by returning to push away the glue cylinder and realize, pushes away the glue cylinder even if return, the remaining pressure in glue the inside still has part to discharge from glue-spreading head, caused glue to overflow, the glue that do not break does not reach accurate some glue effect.
Summary of the invention
