Residual-glue-free glue spraying device and glue removing method for glue spraying head

Abstract

The invention relates to the technical field of automatic glue spraying, in particular to a residual-glue-free glue spraying device and a glue removing method for a glue spraying head. The glue spraying device comprises a mechanical arm, the glue spraying head and a glue removing spraying head, the glue removing spraying head is used for spraying a solvent, the solvent is a corresponding type of solvent capable of dissolving the glue in the glue spraying head, the glue removing spraying head is arranged in the moving range of the mechanical arm, the mechanical arm drives the glue spraying headto move to be close to and face the glue removing spraying head to remove the glue, and the glue removing spraying head sprays the solvent onto the glue spraying head. The glue removing spraying headis arranged to spray the solvent to the glue spraying head, solidified residual glue can be removed, unsolidified residual glue is prevented from being solidified, then the glue spraying head is keptsmooth in glue discharging, and the completion quality of the glue spraying procedure is guaranteed; with adoption of the glue removing mode, the glue removing action can be completed in an extremely-short time, and the influence on the production efficiency can be ignored.

Description

technical field [0001] The invention relates to the technical field of automatic glue spraying, in particular to a glue spraying device without glue residue and a glue cleaning method for a glue spraying head. Background technique [0002] The glue spray head is a kind of equipment for spraying glue. After the glue spray head works, there will be glue left. After the residual glue is cured, the nozzle will be blocked, which will affect the normal use of the glue spray head. In order to solve the above problems, the structure of the glue spray head is generally improved to reduce the glue residue on the glue spray head. Due to the movement of the glue spray head and air turbulence during the glue spray operation, it is inevitable that the glue will stick. On the glue spray head, although a small amount of glue will not cause blockage of the spray head after curing, it will partially block the spray shape of the glue, resulting in uneven spray. Simply improving the glue spray...

[0002] The glue spray head is a kind of equipment for spraying glue. After the glue spray head works, there will be residual glue. After the residual glue solidifies, it will block the nozzle and affect the normal use of the glue spray head.

In order to solve the above problems, the structure of the glue spray head is generally improved to reduce the glue residue on the glue spray head. Due to the movement of the glue spray head and air turbulence during the glue spray operation, it is inevitable that the glue will stick. On the glue spray head, although a small amount of glue will not cause blockage of the spray head after curing, it will partially block the spray shape of the glue, resulting in uneven spray

Simply improving the glue spray head cannot completely solve the problem of glue residue, so the existing equipment introduces a glue cleaning brush head, that is, a rotating brush head is used to scrape the glue spray head, and the adhered residue is removed by external force. Glue brush removal, but this method has the following defects. It takes 5s-10s for each cleaning to ensure the effective removal of residual glue. The accumulation of cleaning time restricts the normal production efficiency; the long-term friction between the brush head and the glue spray head It will adversely affect the life and accuracy of the glue spray head
