Description

Lens carrying fixture

【Technical field】

The invention relates to a lens carrying jig.

【Background technique】

With the rapid development of multimedia technology, digital cameras and video cameras are becoming more and more popular among consumers. While people put forward higher requirements for the image quality of objects captured by digital cameras and video cameras, the demand for digital cameras, video cameras and other products is also increasing.

Optical components such as lenses are indispensable components in photographic devices such as digital cameras and video cameras. In the scheme of mass production of digital cameras and camcorders, high-refractive index optical plastic injection molding optical components have become the mainstream of digital cameras and camcorders.

After the lens is self-injected and placed on the traditional carrier fixture, the upper and lower carrier fixtures need to be fixed with screws before the plastic lens can be sent to the next station for inspection, coating and assembly. However, one more processing procedure is required in the manufacturing process, which will reduce the productivity of the production line, and it is easy to cause the surface of the lens to be dirty during the operation of fixing the screws.

【Content of invention】

In view of the above problems, it is necessary to provide a lens carrying jig that can improve process efficiency.

A lens carrying jig for carrying lenses, which includes two trays, the trays are provided with a plurality of accommodating holes for accommodating the lenses, the lenses are provided with an optical part, and the accommodating holes are stepped hole, which includes a light-through part, and the two carrier discs are attracted to each other and stacked by magnetic principles, and the plurality of accommodating holes on the stacked two carrier discs are respectively aligned to form a housing space, and the lens is accommodated in the housing placed in the space, the optical part of the lens is exposed through the light-transmitting part.

Compared with the prior art, the lens carrying jig uses the principle of magnetism, which can reduce the operation steps of fixing the carrier plate with screws, shorten the fixing time of the carrier plate, and reduce the chance of lens contamination caused by personnel operation errors, thereby Improve process efficiency.

Fig. 2 is a perspective view of a preferred embodiment of the lens carrying jig of the present invention.

【Detailed ways】

Please refer to FIG. 1 and FIG. 2 , a preferred embodiment of the lens carrying jig of the present invention includes two carrier trays 10 . The lens carrying fixture is used to accommodate and hold the lens 20, wherein the lens 20 is a plastic lens, which includes an optical part 200 and a base 202, and the optical part 200 is located in the middle of the base 202, which is spherical or aspherical .

The two carrier discs 10 are respectively a thin plate, which is made of paramagnetic materials such as iron, cobalt, nickel, etc. A strong magnetic field is applied to one of the carrier discs 10, so that the magnetic domains in the material of the carrier disc 10 are arranged, and the The carrier discs 10 are magnetic, or one of the carrier discs 10 is a magnet. The two carrier discs 10 are provided with a plurality of accommodating holes 12, and the plurality of accommodating holes 12 are through holes arranged on the carrier discs 10 according to certain rules. The hole is used for accommodating and holding the lens 20. The accommodating hole 12 is a stepped through hole, including a coaxial light-transmitting portion 120 and an accommodating portion 122, and the diameter of the light-transmitting portion 120 is smaller than the accommodating portion The diameter of the part 122, thereby forming a step at the junction of the two. The diameter of the light-transmitting part 120 is equivalent to the diameter of the optical part 200 of the lens 20, and the diameter of the accommodating part 122 is equivalent to the outer diameter of the base 202 of the lens 20. When the lens 20 is placed in the accommodating hole 12, the base 202 is located in the accommodating part 122, and the optical part 200 can be exposed through the light-transmitting part 120, so that the follow-up process of the lens 20 can be carried out. The light-transmitting part 120 can also be a horn-shaped The circular hole, that is, the diameter of one end connected to the accommodating portion 122 is equivalent to the diameter of the optical portion 200 of the lens 20, and the diameter of the other end is larger.

During the operation, place the magnetic carrier plate 10 with one surface of the light-transmitting portion 120 facing down, and place a plurality of lenses 20 in the accommodation portions 122 of the plurality of accommodation holes 12 of the carrier plate 10 respectively. A carrier disc 10 is opposite to this carrier disc 10, that is, the light-transmitting portion 120 of the other carrier disc 10 lives above its accommodating portion 122, and makes the light-transmitting portion 120 and the light-transmitting portion 120 or the accommodating portion of the carrier disc 10 below it. After the optical portion 200 of the lens 20 in the hole 12 is aligned, it is pressed on the top of the carrier plate 10. Since the carrier plate 10 below is magnetic and the carrier plate 10 above is a paramagnetic material, the upper and lower carrier plates 10 are connected to each other. suction, so that the two carrier discs 10 are relatively fixed. At this time, a part of the base 202 of the lens 20 is located in the accommodation portion 122 of the lower tray 10, and the other part is located in the accommodation portion 122 of the upper tray 10, that is, the lens 20 is accommodated in the lower tray 10. The accommodating portion 122 and the accommodating portion 122 of the upper tray 10 form an accommodating space. At the same time, the optical portion 200 of the lens 20 is exposed through the light-transmitting portion 120 of the two discs 10 .

Apparently, the two carrier discs 10 can be both magnetic, and the opposing surfaces of the two carrier discs 10 are magnetically opposite when they are fastened together. Of course, magnetic components can also be provided only at the four corners of one carrier 10 , and the other carrier 10 is attracted by the magnetic components to achieve the effect of holding the two carriers together. In order to facilitate alignment when the two carrier plates 10 are fastened together, two guide columns can be provided on one carrier plate 10 , and guide holes can be correspondingly provided on the other carrier plate 10 .

The lens carrying fixture utilizes the principle of magnetism, which can reduce the operation steps of fixing the carrier plate 10 with screws, shorten the time for fixing the carrier plate 10, and reduce the possibility of contamination of the lens 20 due to human error, thereby improving the process efficiency.
