Glue dispenser for lens module assembling

Abstract

A glue dispenser (40), for dispensing adhesive in assembling a lens module, includes a dispensing portion (41). The dispensing portion has a top side (411), a bottom side (412) positioned opposite to the top side, and a sidewall (413) connected to the top side and the bottom side. The dispensing portion further includes a main flow passage (415) for transporting adhesive therethrough and a plurality of feed flow passages (416). The main flow passage runs perpendicular from the top side toward the bottom side of the dispensing portion. The feed flow passages communicate with the main flow passage and radially extend to a joint of the side wall and the bottom side. At such a joint, the respective feed flow passages terminate and form a plurality of output ports (417) along an outer circumference of the bottom side.

Claims

1. A glue dispenser configured for dispensing adhesive in a process of assembling a lens module, comprising: a dispensing portion having a top side, a bottom side positioned opposite to the top side, and a sidewall connecting to the top side and the bottom side, the dispensing portion including: a main flow passage configured for containing adhesive therein, the main flow passage running perpendicular from the top side toward the bottom side of the dispensing portion; anda plurality of feed flow passages communicating with the main flow passage, the feed flow passages radially extending to a joint of the sidewall and the bottom side to thus form a plurality of output ports along an outer circumference of the bottom side.

2. The glue dispenser as claimed in claim 1, wherein each respective output port is equally spaced from each adjacent output port.

3. The glue dispenser as claimed in claim 1, wherein the output ports are circular openings.

4. The glue dispenser as claimed in claim 1, wherein the output ports are stripe-shaped openings.

5. The glue dispenser as claimed in claim 1, wherein the dispenser further includes a piston portion movably engaged with and fluidly sealing the main flow passage.

6. The glue dispenser as claimed in claim 5, wherein the piston portion is manually controlled by an operator.

7. The glue dispenser as claimed in claim 5, wherein the piston portion is automatically controlled by a computer.

8. The glue dispenser as claimed in claim 1, wherein the dispensing portion further comprises an annular ring projecting from the bottom side.
