The present invention generally relates to washing mechanisms and, more particularly, to a washing mechanism for optical members such as optical lenses, optical filters, or such like.
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 process of manufacturing, the optical lenses need to be washed before plating a film thereon. A typical washing mechanism for optical members includes a housing full of water, an ultrasound producer, and a washing box retaining some water therein. The ultrasound producer is mounted at the bottom of the housing. The washing box is mounted in a top portion of the housing and touches the water. In use, one optical member is disposed in the washing box and the optical member immerges in the water. The ultrasound producer produces ultrasonic wave to enable the water in the washing box to wash the optical member. However, the washing mechanism only washes one optical member one time.
Therefore, a new washing mechanism is desired in order to overcome the above-described shortcomings.
In one embodiment thereof, an washing mechanism for optical members includes a positioning assembly, a carrying assembly, and an adjusting assembly. The carrying assembly is mounted on the positioning assembly and includes a plurality of poles and a plurality of slidable members. The slidable members are configured for holding optical members. Each slidable member is slidably mounted on a corresponding pole. The adjusting assembly is mounted on the positioning assembly and the carrying assembly and configured for adjusting a position of the carrying assembly.
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.
Many aspects of the present washing mechanism can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the washing mechanism and its potential applications. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Referring now to the drawings in detail,
The positioning assembly 10 includes a top board 12, a bottom board 14, and a plurality of supporting pillars 16. In this preferred embodiment, there are four supporting pillars 16. Both the top board 12 and the bottom board 14 are rectangular boards in shape. The top board 12 defines a plurality of top holes 122 therethrough. In this preferred embodiment, there are three top holes 122. The three top holes 122 are positioned in a substantially T-shaped formation. The bottom board 14 defines a plurality of bottom holes 142 therethrough. In this preferred embodiment, there are three bottom holes 142. The three bottom holes 142 are positioned in a substantially T-shaped formation. Each top hole 122 is positioned above a corresponding one of the bottom holes 142. Each supporting pillar 16 is mounted on the top board 12 and the bottom board 14, and between a corner of the top board 12 and a corresponding corner of the bottom board 14. The top board 12, the bottom board 14, and the supporting pillars 16 cooperate to form a space for receiving the carrying assembly 20.
Further referring to
Each sleeve 24 is substantially a hollow cylinder in shape and defines a slot 242 therein. An inner diameter of the sleeve 24 is slightly larger than a diameter of the pole 22, so that the pole 22 may be slidably received in the sleeve 24. The length of the sleeve 24 is shorter than that of the pole 22, so that when the pole 22 is received in the sleeve 24, the end with the screw thread 222 and the end with the screw thread 224 are exposed out of the sleeve 24 simultaneously.
The carrying part 26 is substantially a rectangular board in shape and may be made of resin. The carrying part 26 defines a plurality of V-shaped grooves 262 at a first side. The slot 242 of the sleeve 24 is configured for receiving a second side of the carrying part 26 therein. The second side of the carrying part 26 is opposite to the first side of the carrying part 26.
The adjusting assembly 30 includes a plurality of nuts 32, 34 and 36 and a plurality of resilient members 38. In this preferred embodiment, there are nine nuts 32, 34 and 36 and three resilient members 38. Each resilient member 38 may be made of metal and may be spiral-shaped (i.e. like a coil spring). The nuts 32, 34 and 36 are configured for engaging with the screw threads 222, 224 of the pole 22 to connect the poles 22 with the boards 12, 14. An inner diameter of the resilient member 38 is slightly larger than the diameter of the pole 22, so that the resilient members 38 may slidably surround the pole 22.
In assembly, one end with the screw thread 224 of each pole 22 is inserted through one top hole 122, one corresponding nut 34, one corresponding sleeve 24, one corresponding resilient member 38, and one corresponding bottom hole 142 in that order. Two opposite ends of the pole 22 are exposed out of the top hole 122 and the bottom hole 142. One nut 32 is mounted to one end with the screw thread 222 of the pole 22, and one nut 36 is mounted to one end with the screw thread 224 of the pole 22, thereby mounting the carrying assembly 20 with the positioning assembly 10. Each resilient member 38 is mounted between the sleeve 24 and the bottom board 14. The first sides of the three carrying parts 26 face each other. The three grooves 262 of the three carrying parts 26 in one horizontal direction cooperate with each other in a manner so as to hold one optical member therein. Thus the washing mechanism 9 is assembled completely, as shown in
In use, the nuts 32, 36 are released so that the carrying assembly 20 can slide up and down between the top board 12 and the bottom board 14 and can slide along the extending direction of the top hole 122 and simultaneously slide along the extension direction of the bottom hole 142. The nuts 32, 36 can be tightened so to fit the dimensions of the optical members that the carrying assembly 20 is fixed between the top board 12 and the bottom board 14. The nut 34 is screwed and the resilient member 38 is compressed or decompressed. At the same time the sleeve 24 slides up or down relative to the other sleeves 24 until the carrying parts 26 are located level with each other. The edge of the optical member is inserted into three grooves 262 positioned in an identical horizontal direction. The optical member is stably held in the carrying assembly 20 by the three carrying parts 26 supporting three points of the optical member. As such a plurality of optical members may be mounted in the washing mechanism 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, in manufacturing, the carrying assembly 20 may be adjusted according to the dimension of various optical members.
It is to be understood that the top board 12 and the bottom board 14 may alternatively have a different configuration such as a circular or polygonal board. The number of the slidable members is not necessarily limited to three. It may be two or more. The resilient members 38 may alternatively be made of another material (e.g. plastic or rubber). The resilient members 38 may alternatively have a different configuration, for example, a leaf spring or a resilient cylinder. The carrying part 26 may be integrally formed as part of the sleeve 24.
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.
