Gluing device

Abstract

The invention provides a gluing device which is used for carrying out gluing operation on a target object. The gluing device comprises a gluing cylinder, a plunger body, a closing valve and a limiting block, wherein the gluing cylinder is provided with a containing cavity, the containing cavity is provided with a first opening and a second opening which are opposite, and the containing cavity is used for containing glue; the plunger body is partially contained in the containing cavity and protrudes out of the containing cavity through the first opening, and the plunger body moves in the containing cavity in the direction from the first opening to the second opening so as to push the glue; the closing valve is fixedly connected with the plunger body so as to synchronously move with the plunger body, the closing valve closes or opens the second opening according to the synchronous movement, and when the closing valve opens the second opening, the plunger body pushes the glue to annularly overflow from the second opening; and the limiting block is connected to the position, located outside the containing cavity, of the plunger body and used for controlling the moving distance of the plunger body in the containing cavity so as to control the glue outlet amount of the glue.

Description

technical field [0001] The invention relates to the technical field of gluing, in particular to a gluing device. Background technique [0002] The traditional gluing method is to move the gluing device in a predetermined direction so that the glue covers a predetermined area. The lens hole of an electronic product is a circular hole. When applying glue to the inner wall of the lens hole, select a position as the starting position, and use the starting position as the starting point to move the gluing device to apply glue to the entire hole wall. The starting point and the end position of gluing will cause the gluing to overlap and cause gluing abnormality. And the lens hole is a circular hole, and the gluing device needs to be inserted into the lens hole and positioned at the center of the circle to help ensure the gluing effect, but it is difficult to align the gluing device with the center of the circle.
