1. Technical Field
The present disclosure relates to assembly devices and, particularly, to a multi-functional assembly device used in lens modules assembly.
2. Description of Related Art
Nowadays, lens modules are widely employed in camera systems and mobile phones for capturing images. Generally, a lens module includes components such as lenses, spacers, and a filter (e.g., IR-cut filter). These components can be assembled into the lens module and arranged along an optical axis of the lens module. In order to assemble these components, a glue dispenser is first used to dispense glue onto the lens module, then, a carrying device carries the components into the lens module, and a glue solidifying device is used to solidify the glue. Therefore, in order to assemble the filter into the lens module, several space-consuming devices are required.
What is needed, therefore, is a multi-functional assembly device to overcome or at least mitigate the above-described problem.
Many aspects of the present multi-functional assembly device can be better understood with reference to the accompanying drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principle of the present multi-functional assembly device. In the drawings, all the views are schematic.
Embodiments of the present disclosure will now be described in detail below, with reference to the accompanying drawings.
Referring to
The fixed barrel 10 is generally hexagonal prism-shaped and symmetrical about the center axis thereof. The fixed barrel 10 includes six sidewalls 11 and a bottom wall 12. The six sidewalls 11 and the bottom wall 12 cooperatively define hexagonal prism-shaped chamber 13. Each sidewall 11 includes an inner surface 111 with a supporting board 20 secured thereon. The bottom wall 12 defines a shaft hole 121 therethrough generally at the center.
Each supporting board 20 is secured on one of the inner surfaces 111 of the sidewall 11. Each supporting board 20 defines a number of holding grooves 21 thereon for holding lens modules 300. Moreover, the supporting boards 20 albeit detachable from the sidewalls 11, can be integrally formed with the sidewalls 11.
It should be understood that the hexagonal prism-shaped chamber 13 is not limited to this embodiment. To reduce or increase the number of the sidewalls 11 for holding less or more supporting boards 20, other types of prism chamber or columnar chamber having less or more sidewalls 11 can be employed.
The rotatable barrel 30 is received in the prism chamber 13. The rotatable barrel 30 includes a prism main body 31, a number of carrying devices 32, a number of glue dispensers 33, and a number of glue solidifying devices 34.
The main body 31 is generally hexagonal prism-shaped and includes two opposite end surfaces 311, two opposite first side surfaces 312, two opposite second side surfaces 313, and two opposite third side surfaces 314. The second side surface 313, the first side surface 312, and the third side surface 314 are connected in sequence. The main body 31 further includes a shaft 315 extending out of the fixed barrel 10 via the shaft hole 121 from one of the end surfaces 311 facing the bottom wall 12 of the fixed barrel 10.
Each of the first side surfaces 312 has a number of carrying devices 32 installed thereon. Referring to
Each of the second side surfaces 313 has a number of glue dispensers 33 installed thereon. Referring to
Each of the third side surfaces 314 has a number of glue solidifying devices 34 installed thereon. The glue solidifying devices 34 are used for solidifying the glue dispensed by the glue dispensers 33. In the present embodiment, the glue dispensed by the glue dispensers 33 is ultraviolet curable glue, and the glue solidifying devices 34 are ultraviolet light emitting devices.
The driving device 40 includes a main body 41 and a rotating shaft 42. The rotating shaft 42 is fixed to the shaft 315 of the rotatable barrel 30, thus, the rotatable barrel 30 can be rotated by the driving device 40.
The controller 50 is electrically connected to and regulates power for the gas valves 322, the linear motors 323, the glue valves 332, the linear motors 333, and the glue solidifying devices. 34.
In operation, the second side surface 313, the first side surface 312, and the third side surface 314 can face the lens modules 300 in sequence by rotating the rotatable barrel 30. Thus, the lens modules 300 can be dispensing glue by the glue dispensers 33 disposed on the second side surface 313 first, then, the components 200 can be place into the lens modules 300 by the carrying devices disposed on the first side surface 312, and then, the glue solidifying devices 34 disposed on the third side surface 314 can solidify the glue dispensed by the glue dispensers 33 to fix the components 200 to the lens modules 300.
While certain embodiments have been described and exemplified above, various other embodiments will be apparent to those skilled in the art from the foregoing disclosure. The invention is not limited to the particular embodiments described and exemplified, and the embodiments are capable of considerable variation and modification without departure from the scope and spirit of the appended claims.
