Description

Fixture for assisting the lens barrel to be screwed into the lens holder

The present invention relates to an optical lens process, and more particularly to a jig for assisting a lens barrel to be screwed into a lens holder.

With the rapid development of multimedia technology, digital cameras, camcorders and mobile phones with cameras are increasingly favored by consumers. While people are demanding higher image quality for digital cameras, camcorders and mobile phone cameras, Lighter and thinner products such as digital cameras, camcorders and mobile phones with cameras have also placed higher demands. The size of the lens module is also getting smaller and smaller.

In the production process of the camera module, the optical components such as the lens, the support post, the spacer ring and the filter are sequentially assembled into the lens barrel, and then the lens barrel is screwed into the lens holder. The traditional method is to manually screw the lens barrel into the lens holder by hand. However, since the lens module is small in size, it is difficult to grasp components, and it is difficult to operate in mass production, which requires a lot of manpower.

In view of the above, it is necessary to provide a jig for assisting the lens barrel to be screwed into the lens holder, which can improve assembly efficiency.

A jig for assisting a lens barrel to be screwed into a lens holder, the jig comprising a lens barrel holding portion and a handle. The lens barrel holding portion is a hollow cylindrical structure. The inner wall of one end of the lens barrel holding portion is provided with a rod, the rod meshes with the lens barrel, and the handle is disposed at the other end of the lens barrel holding portion for rotating the lens barrel holding portion.

Compared with the prior art, it is more convenient and labor-saving to use the auxiliary jig of the invention to screw the lens barrel, and the speed of assembling the lens barrel can be accelerated.

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

Referring to FIG. 1, a first embodiment of the present invention provides an auxiliary fixture 10 into which a lens barrel 20 is screwed into a lens holder 22. The auxiliary jig 10 includes a lens barrel holding portion 12 and a handle 14. The lens barrel holding portion 12 is a hollow cylindrical structure. A rod 124 is disposed on an inner wall of one end of the barrel holding portion 12, and the shape of the rod 124 is completely or partially matched with the shape of the bottom focus ring 200 of the barrel 20. When the lens barrel 20 is gripped, the lens barrel holding portion 12 is engaged with the lens barrel 20 by the rod teeth 124 for fixing and gripping the lens barrel 20. The handle 14 is disposed at the other end of the lens barrel holding portion 12 for rotating the lens barrel holding portion 12. The handle 14 is a prism. The barrel holding portion 12 and the handle 14 may be integrally formed. Preferably, the handle 14 is coaxial with the barrel holding portion 12, and when the handle 14 is rotated along its central axis, the barrel holding portion 12 also rotates.

The material of the handle 14 may be an engineering plastic, including nylon, acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), polypropylene (PP). And polycarbonate (Polycarbonate, PC). The material of the handle 14 may further be doped with glass fibers.

A second embodiment of the present invention provides a jig 30 for assisting a lens barrel to be screwed into a lens holder. The auxiliary jig 30 includes a lens barrel holding portion 12 and a handle 34. The lens barrel holding portion 12 is a hollow cylindrical structure. A rod 124 is disposed on an inner wall of one end of the barrel holding portion 12, and the shape of the rod 124 is completely or partially matched with the shape of the bottom focus ring 200 of the barrel 20. When the lens barrel 20 is gripped, the lens barrel holding portion 12 is engaged with the lens barrel 20 by the rod teeth 124 for fixing and gripping the lens barrel 20. The handle 34 is disposed at the other end of the lens barrel holding portion 12 for rotating the lens barrel holding portion 12 . Preferably, the handle 34 is coaxial with the barrel holding portion 12, and when the handle 34 is rotated along its central axis, the barrel holding portion 12 also rotates. The handle 34 is a cylinder. The surface of the cylindrical handle 34 has at least one holding groove 340. The surface of the holding groove 340 may be a spherical surface, may be an ellipsoidal surface, or may be any shape. The handle 34 may also have protrusions or granules of any shape on the surface to increase the friction of the hand or robot with the surface of the handle 34.

When using the above auxiliary fixture, first lock the lens barrel into the lens barrel holding portion, and then use the hand or the robot to hold the handle to rotate the lens barrel into the lens holder, and finally remove the auxiliary fixture. Since the fixture has a handle and the rib or groove on the handle increases the friction between the hand or the manipulator and the handle, it is more convenient and labor-saving when screwed into the lens barrel, and is ergonomically capable of accelerating the assembly of the lens barrel. speed.

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.
