Description

1. FIELD OF THE INVENTION

The present invention generally relates to clamping apparatuses and, more particularly, to a clamping apparatus configured for washing optical members such as optical lenses, optical filters, or such like.

2. DESCRIPTION OF RELATED ART

With the ongoing development of microcircuitry and multimedia technologies, digital cameras have become a highly popular way of taking pictures. High-end portable electronic devices, such as mobile phones and personal digital assistants (PDAs), are being developed to include increasing numbers of special features. Many of these portable electronic devices are now equipped with a digital camera module, these electronic devices enable consumers to enjoy capturing digital pictures anytime and anywhere, the smallest and most eye-catching cameras being the most popular.

In camera modules, optical lenses are very important to the quality of the pictures captured by the camera modules. In the manufacturing process, the optical lenses need to be washed before plating a film thereon. Generally, optical elements are washed with ultrasonic waves in a vessel filled with liquid. The optical elements are prone to collide with each other under the influence of the ultrasonic waves. As a result, a surface of each optical element may easily be scraped or damaged. Therefore, optical elements need to be fixed in a clamping apparatus so that the optical elements are separated from each other and do not collide with each other.

A typical clamping apparatus is a holding board defining a plurality of receiving holes therein. Each receiving hole has a shape and size corresponding to the optical element. In use, each optical element is received in one of the receiving holes, and the holding board is then put in a liquid to be washed with ultrasonic waves. Because all the optical elements are received in the receiving holes, impurities on surfaces of the optical elements touching the holding board may not be removed.

Therefore, a new clamping apparatus is desired in order to overcome the above-described shortcomings.

SUMMARY OF THE INVENTION

In one aspect thereof, a clamping apparatus for washing optical members includes a top fixture and a bottom fixture. The top fixture has a top washing slot defined therein. The bottom fixture has a bottom washing slot defined therein. The bottom washing slot communicates with the top washing slot. The bottom fixture and the top fixture are mounted together for receiving the optical members.

Other advantages and novel features of the embodiments will become more apparent from the following detailed description thereof when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Referring now to the drawings in detail, FIG. 1 shows a clamping apparatus 9 of a preferred embodiment of the present invention. The clamping apparatus 9 is capable of washing a plurality of optical members at once. The optical members may be optical lenses, optical filters, or such like. The clamping apparatus 9 includes a top fixture 10, a bottom fixture 20, a holder 30, two securing members 40, and two bolts 50. The top fixture 10 and the bottom fixture 20 are fixed together with the securing members 40. The fixed top fixture 10 and bottom fixture 20 are mounted to the holder 30 with the two bolts 50.

Also referring to FIG. 2, the top fixture 10 is a rectangular board in shape and has a top surface 11 and a bottom surface 12. The top surface 11 is opposite to the bottom surface 12. The top fixture 10 defines a top washing slot 13 therethrough. The top washing slot 13 is rectangular in shape and extends from one end of the top fixture 10 to the other opposite end of the top fixture 10. A top groove 14 is defined in the top surface 111 at each of two opposite ends of the top fixture 10.

Also referring to FIG. 3, the bottom fixture 20 includes two positioning sidewalls 22 and two positioning blocks 23. Two ends of each positioning sidewall 22 connect with the two positioning blocks 23 respectively, thereby forming a bottom washing slot 24. A height of each positioning sidewall 22 is larger than that of each positioning block 23.

Each positioning sidewall 22 is a rectangular board in shape and has a top surface 220 and a bottom surface 221. The top surface 220 is positioned opposite to the bottom surface 221. Each positioning sidewall 22 defines a plurality of receiving cavities 222 in the top surface 220. The receiving cavities 222 all communicate with the bottom washing slot 24. Each receiving cavity 222 is arcuate in shape, corresponding to a rim of the optical member. Each receiving cavity 222 of one positioning sidewall 22 cooperates with one corresponding receiving cavity 222 of another positioning sidewall 22 to receive one optical member. A bottom groove 223 is defined in the bottom surface 221 at each of two opposite ends of each positioning sidewall 22. The bottom grooves 223 of the bottom fixture 20 are for engaging with the top grooves 14 of the top fixture 10. Each positioning sidewall 22 defines a side washing slot 225 therethrough along a horizontal direction. The side washing slot 225 communicates with the bottom washing slot 24.

Also referring to FIG. 4, the holder 30 includes two base poles 31, two supporting arms 35, a bottom connecting pole 33, and a top connecting pole 37. The base poles 31, the supporting arms 35, the bottom connecting pole 33, and the top connecting pole 37 are all rectangular in shape. The two base poles 31 are parallel to each other. Each supporting arm 35 is perpendicularly formed at a central portion of each base pole 31, thus the supporting arms 35 are parallel to each other. The bottom connecting pole 33 connects bottom ends of the supporting arms 35. The top connecting pole 37 connects top ends of the supporting arms 35. The bottom connecting pole 33 is parallel to the top connecting pole 37. The bottom connecting pole 33 defines a plurality of mounting holes 330 therein. The top connecting pole 37 defines a plurality of mounting holes 370 therein. The mounting holes 330, 370 are screw holes.

Each of the securing members 40 is a cord or an elastic band. The securing member 40 may be made of metal, plastic, or rubber. The securing members 40 are configured for being secured in the top grooves 14 and the bottom grooves 223 for fixing the top fixture 10 to the bottom fixture 20. The bolts 50 are configured for being secured in the mounting holes 330, 370 for fixing the top fixture 10 and the bottom fixture 20 to the holder 30.

In use, a plurality of optical members are disposed in the receiving cavities 222 of the bottom fixture 20. The top fixture 10 is disposed on the top surface 220 of the bottom fixture 20 with the bottom surface 12 of the top fixture 10 on the top surface 220. The top fixture 10 is fixed to the bottom fixture 20 with two securing members 30 being secured in the top grooves 14 and the bottom grooves 223. The assembled top fixture 10 and bottom fixture 20 are fixed to the bottom connecting pole 33 and the top connecting pole 37 with the bolts 50 being secured in the mounting holes 330, 370. As such, a plurality of optical members may be mounted in the clamping apparatus 9 ready for washing. After washing, the washed optical members can be taken out from the carrying assembly 20.

It is to be understood that the receiving cavity 222 is not limited to being arcuate in shape. The receiving cavity 222 may alternatively have a different configuration corresponding to a shape of the optical member.

It is to be understood, however, that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
