when the one end of the sponge strip 91 rotates to the upper edge of the separating part 31 along with the separating disc 3, the negative pressure air suction port on the winding part 41 is communicated with the negative pressure source to provide suction force for the sponge strip 91 on the separating part 31, the one end of the sponge strip 91 is sucked into the winding part 41 of the winding disc 4, along with the relative rotation of the winding disc 4 and the separating disc 3, the other part of the sponge strip 91 is gradually sucked into the winding part 41 along with the one end, and one end is wound and connected into annular padding cotton along with the rotation of the winding part 41, and at the moment, the back surface with the backing adhesive layer faces upwards so as to be attached to the loudspeaker; and the rotational linear speeds of the separating portions 31 are preferably the same as the rotational linear speeds of the winding portions 41;
the blanking manipulator 81 clamps the loudspeaker to be right above the winding disc 4, then the lifting cylinder 83 acts to enable the blanking manipulator 81 to move downwards, the surface with the joint of the loudspeaker is placed on the back glue layer of the pad cotton, the loudspeaker and the pad cotton are mutually jointed, then the blanking manipulator 81 moves upwards and moves along the x axis to move the joint out of the pad cotton loudspeaker, and blanking is achieved.
This former separates the storage, the material loading of bar sponge (containing 3M double faced adhesive tape, 30 sponges above a piece of gum paper), a sponge strip and automatic wiring becomes circular shape (the diameter size freely switches over according to the product frock) realizes automatic assembly, and this station is by original 4~5 people wiring and assembly, can utilize two this equipment replacement manual operation after the realization, foresees after putting into production in batches to practice thrift about the number of people 100.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and are preferred embodiments, which are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention.
