Abstract
A method for assembling a lens module includes the following steps. Firstly, a lens barrel, at least one optical element, a spacer ring, and a fixing ring are provided. The spacer ring includes an annular projection along a circumference of the spacer ring. The fixing ring includes a annular pipe and glue received in the pipe. The film is made of ethylene-vinyl acetate copolymer. Secondly, the at least one optical element and the spacer ring are put into the barrel, with an annular groove defined between the projection and the barrel. Thirdly, the fixing ring is placed in the groove. Fourthly, the fixing ring is heated and the film is melted to let the glue fill the groove. Finally, the glue is cured to fix the spacer ring and the at least one optical element in the barrel.

A method for assembling a lens module, comprising:
- providing a lens barrel, an optical element, a spacer ring and a fixing ring, the spacer ring having a ring body and an annular protrusion protruding from a first side surface of the ring body, the fixing ring comprising an annular pipe and a glue received in the pipe, the pipe made from poly(ethylene vinyl acetate);
- placing the at least one optical element and the spacer ring into the lens barrel, the first side surface facing away from the optical element, the annular protrusion and the lens barrel cooperatively defining an annular groove therebetween;
- placing the fixing ring in the annular groove;
- heating the fixing ring to melt the pipe such that the glue is released to fill the annular groove;
- and
- curing the glue in the annular groove.
A lens module, comprising:
- a lens barrel;
- at least one optical element received in the lens barrel;
- a spacer ring received in the lens barrel, the spacer ring having a ring-shaped body and an annular protrusion formed on a first side surface of the ring-shaped body, the first side surface facing away from the at least one optical element, the annular protrusion and the lens barrel cooperatively defining an annular groove therebetween;
- and
- a glue received and cured in the annular groove.
