Nozzle and suction device

The present invention relates to a nozzle for sucking a lens, and a suction device having the same.

With the development of multimedia technology, digital cameras, cameras and other camera devices are increasingly favored by consumers. The existing camera device, such as a digital camera, is generally composed of a lens barrel and an optical lens housed in the lens barrel. See Edward H. Adelson et al., IEEE Transactions on Pattern Analysis and Machine Intelligence, Vol. 14, No. .2, Single Lens Stereo with a Plenoptic Camera on February 1992. Due to the miniaturization of the lens module, the size of the lens is getting smaller and smaller, and as the product is diversified, the type of the outer diameter of the lens also increases.

In the automated manufacturing process of the lens module, the nozzle is generally used for the process of cutting the lens gate or assembling the lens module. Generally, the size of the adsorption holes of the nozzles used in the above process is specifically designed for the outer diameter and the aspherical diameter of the lens to be processed, so that it can be applied to a specific size to be processed. lens. If the size of the lens to be processed changes, it is necessary to redesign the nozzle having the appropriate size of the adsorption hole according to the new size of the lens to be processed.

In view of the above, it is necessary to provide a suction nozzle suitable for sucking a plurality of lenses of different sizes and a suction device having the same.

In the following, a nozzle and a suction device having such a nozzle, which can be used to suck a plurality of lenses of different sizes, will be described with reference to specific embodiments.

Compared with the prior art, the suction nozzle and the suction device having the same have a plurality of different sizes because the adsorption hole is a stepped hole penetrating the nozzle body, and the stepped hole has a plurality of different diameters, so that it can be used for sucking a plurality of different sizes. The size of the lens.

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 , a nozzle 10 according to a first embodiment of the present invention includes a nozzle 10 . The body 11 and an adsorption hole 12.

The body 11 is substantially cylindrical and includes two opposite first end faces 110 and second end faces 112. The material of the body 11 may be a hard material such as metal.

The adsorption hole 12 is disposed on the body 11 and penetrates through the first end surface 110 and the second end surface 112 of the body 11 . The adsorption hole 12 is a stepped hole having a first-order hole 121, a second-order hole 122, a third-order hole 123, and a fourth-order hole 124, which are sequentially reduced in diameter from the first end surface 110 to the second end surface 112. The diameters of the first-order hole 121, the second-order hole 122, the third-order hole 123, and the fourth-order hole 124 are d ₁ , d ₂ , d _{3 ,} and d _{4 , respectively} . Since the adsorption hole 12 is used for adsorbing the lens to be processed, the steps of the adsorption hole 12 are generally arranged to be holes having a shape matching with the lens to be processed, such as the first-order holes 121 of the adsorption hole 12 in this embodiment (ie, the first-order hole 121, The second-order holes 122, the third-order holes 123, and the fourth-order holes 124) are circular holes.

Since the suction holes 10 of the nozzle 12 having a plurality of different size diameter, so that the suction nozzle 10 is adapted to absorb a plurality of different sizes of lenses, for example: Referring to Figure 2, when using the suction nozzle 10 of an outer diameter d ₁ when the lens 30, the lens 30 than the edge is one of _an order of diameter d hole wall of the hold of the card 121, and at least a portion of the entire lens 30 is housed in the suction holes 12, thereby providing suction in the suction holes 12 The lens 30 will be sucked up by the suction nozzle 10 during vacuum operation.

Similarly, when the nozzle 10 is used to suck the lens having the outer diameter d ₂ , the outer edge of the lens is held by the hole wall of the second-order hole 122 having the diameter d2, and at least a part of the entire lens is received by the adsorption hole 12 . When the nozzle 10 is used to suck the lens having the outer diameter d ₃ , the outer edge of the lens will be held by the hole wall of the third-order hole 123 having the diameter d ₃ , and at least a part of the entire lens is adsorbed. 12 contained in the inside.

Preferably, the wall of the hole of the adsorption hole 12 is further provided with a layer of elastic material 13, such as rubber, which can act as a buffer when the nozzle 10 sucks the lens, thereby preventing the nozzle 10 from damaging the lens.

Referring to Figures 3 and 4, a second embodiment of the present invention also provides a suction device 20. The suction device 20 includes a hollow tubular body 21, and a suction nozzle 10 and a suction source 22 respectively disposed at both ends of the hollow tubular body 21.

The hollow tubular body 21 may have a cylindrical shape, and the inside thereof includes a flow passage 210 through which the airflow can pass, the flow passage 210 communicates with the adsorption hole 12 of the suction nozzle 10, and the hollow tubular body 21 is located at the adsorption hole. The opening diameter of 12 is one side of the smaller diameter. Of course, the shape of the hollow tubular body 21 is not limited to a cylindrical shape, and it may also be a prismatic shape or other irregular shape.

The suction source 22 is in communication with the flow channel 210, which may be a vacuum supply device such as a vacuum pump or the like. The suction source 22 can provide different degrees of vacuum to the hollow body 21 so that the lens can have different suction forces to facilitate holding or placing the lens.

It should be noted that the lens 30 to be processed shown in FIG. 2 is a lenticular lens having an outer diameter d ₁ , and when at least a part of the lens 30 is received in the one-step hole 121 of the diameter d ₁ of the adsorption hole 12 , the lens The convex surface of 30 will be accommodated in the second-order hole 122 of the diameter d ₂ of the adsorption hole 12 to avoid damage caused by direct contact with the body 11. The accommodation space of the second-order hole 122 should be at least large enough to accommodate the lens 30. The raised face area, i.e., the depth of the second order hole 122, is greater than or equal to the height of the raised face of the lens 30. Therefore, directed to an outer diameter d ₁ of the lens 30, the nozzle 10 of the suction hole 12 should have at least a first order and a second order aperture 121 aperture 122. Considering that the nozzle 10 is at least applied to the lenticular lens having the outer diameter d ₂ , the adsorption hole 12 of the nozzle 10 should also include at least one third-order hole 123 for receiving the convex surface of the lens having the outer diameter d2. Therefore, the adsorption hole 12 is at least a third-order stepped hole, which may also be a fourth-order stepped hole, a fifth-order stepped hole, or the like, that is, the adsorption hole 12 may have three, five or even different diameters.

In addition, the diameter of each step hole of the adsorption hole 12 can be appropriately designed and adjusted according to the outer diameter of the lens to be processed to meet the needs of a plurality of lenses of different sizes, and the diameter relationship of each step of the adsorption hole 12 is not affected. It is limited to be sequentially reduced in the direction from the first end face 110 to the second end face 112, and any diameter change relationship that can achieve the technical effects of the present invention can be used. The shape of the body 11 is not limited to a cylindrical shape, and may be a prism shape or the like.
