Cleaning device

The present invention relates to a cleaning device, and more particularly to a cleaning device for cleaning a hollow molded part.

With the development of multimedia technology, imaging devices such as cameras, digital cameras, and mobile phones with camera functions are increasingly favored by consumers. When people pursue miniaturization of cameras, digital cameras, and mobile phones, they are shooting The image quality of the object has a higher requirement, that is, the image of the object to be photographed is clear, and the image quality of the object largely depends on the advantages and disadvantages of the optical instruments in the camera.

The hollow plastic injection molding used in the optical module of the above imaging device comprises a lens barrel, a lens holder and a spacer ring. After injection molding, the surface of the molded part will contain an oily release agent, which needs to be cleaned to remove chemical substances and dust on the surface before performing subsequent processes (for example, coating or assembly).

The general cleaning device comprises an upper cover and a lower cover. The upper cover and the lower cover are screwed and sealed, and the upper cover and the lower cover are respectively provided with a plurality of small holes, so that the water flow can take away the dirt on the surface of the molded part during cleaning. The material of the upper cover and the lower cover is generally stainless steel. However, the stainless steel device is relatively bulky. Generally, only a few of the above-mentioned stainless steel devices can be placed in an ordinary ultrasonic cleaning tank, so the number of molded parts is limited each time. Moreover, it is not easy to clean the molded part by placing an excessive amount of the molded part in one apparatus.

In view of the above, it is necessary to provide a cleaning device that can more efficiently clean molded parts.

A cleaning device for cleaning a hollow molded part, the cleaning device comprising a base and a plurality of supporting columns, the base having a surface, the supporting column has a free end, and the plurality of supporting columns are respectively fixed on the surface of the base And the free end of the support column is away from the bottom plate.

Compared to the prior art, the plurality of support columns of the cleaning device can allow the molded part to be placed thereon, and the volume is small. In a general-sized ultrasonic cleaning tank, a plurality of cleaning devices can be placed, and each cleaning device can include a plurality of supporting columns, thereby increasing the number of cleaning molded parts at one time, thereby improving productivity and being advantageous for mass production. Moreover, the parts to be washed are dispersed on the respective support columns of each device, so that the molded parts can be cleaned more cleanly.

Schematic diagram of the support column of the cleaning device.

4 is a schematic view of a support column of a cleaning device according to a third embodiment of the present invention.

The invention will now be described in further detail with reference to the accompanying drawings.

Referring to Figures 1 and 2, a first embodiment of the present invention provides a cleaning apparatus 10 for cleaning a hollow molded part 18. The cleaning device 10 includes nine support columns 12, a base 14 and three partition plates 16.

The support post 12 has a fixed end 122 and a free end 124 opposite the fixed end 122. The fixed end 122 is provided with at least one first fixing unit 126. In this embodiment, the first fixing unit 126 is a cylinder whose central axis is parallel to the central axis of the support column 12.

Of course, the first fixing unit 126 can also be a groove.

The base 14 has a surface 142. The surface 142 is provided with nine second fixing units 144 respectively for use with the nine first fixing units 126 to fix the fixed end 122 of the support post 12 to the base 14 , and the free end 124 is away from the base 14 . Preferably, in the embodiment, the second fixing unit 144 is a circular groove, and the plurality of second fixing units 144 are arranged in a matrix on the base 14.

Of course, the support column 12 can also be integrally formed with the base 14. The number of the support columns 12 can also be determined according to actual conditions.

The partition plate 16 is provided with through holes 162 arranged in the same manner as the support columns 12 so that the support columns 12 penetrate the partition plate 16 to divide each support column 12 into four segments. Of course, the number of the spacers 16 may also be one, two, four or more. Of course, there may be no spacers 16.

The material of the support column 12, the base 14 and the partition plate 16 is one of aluminum, aluminum alloy, stainless steel, titanium alloy, copper and heat-resistant engineering plastic, and can be processed by computerized numerical control (CNC) processing technology. .

The cleaning device 10 is used in the following manner: first, the first fixing unit 126 is inserted into the second fixing unit 144, so that the fixed end 122 of each supporting column 12 is fixed on the base 14, and the plurality of moldings 18 are respectively disposed on the support. The spacers 16 are then placed on the support columns 12; the plurality of moldings 18 are respectively placed on the support columns 12, and the other spacers 16 are placed on the support columns 12, and thus repeated. So that each support column 12 Each section has a molding member 18; the cleaning device 10 is placed in the ultrasonic cleaning tank for cleaning; after the cleaning is completed, each of the partitioning plates 16 and the molding member 18 thereon and in contact therewith are removed in turn, and The molded part 18 in contact with the base 14 is removed.

Of course, the partition 16 and the other molded parts 18 and other spacers 16 located closest to the base 14 can be removed at a time, and the molded piece 18 in contact with the base 14 can be removed.

Preferably, in this embodiment, the plurality of support columns 12 are parallel to each other and perpendicular to the surface 142 of the base 14.

It can be understood that the plurality of support columns 12 can also be non-parallel to each other, and is not limited to the embodiment, as long as the free end 124 of the support column 12 is away from the surface 142 of the base 14.

Of course, the support column 12 may also not be perpendicular to the surface 142 of the base 14.

In the cleaning device 10 provided by the first embodiment of the present invention, the plurality of support columns 12 can pass the molded member 18 to be cleaned thereon, and the volume is small. In a conventional ultrasonic cleaning tank, a plurality of cleaning devices 10 can be placed. Each cleaning device 10 can include a plurality of support columns 12, thereby increasing the number of cleaning moldings 18 at a time, thereby increasing productivity and being advantageous for mass production. Moreover, the molded part 18 to be cleaned is dispersed on each of the support columns 12, so that the molded part 18 to be cleaned can be cleaned more cleanly.

Referring to FIG. 2, a second embodiment of the present invention provides a support column 12a of a cleaning device. The support column 12a is different from the support column 12 in that the first fixing unit 126a of the fixed end 122a of the support column 12a is a hemisphere. body.

Referring to FIG. 3, a third embodiment of the present invention provides a support column 12b of a cleaning device. The support column 12b is different from the support column 12 in that the fixed end 122b of the support column 12b is provided with a first fixing unit 126b. body.

Of course, the shape of the first fixing unit may also be other geometric shapes such as a triangular prism, a quadrangular prism or a pentagonal prism.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
