Description

Technical Field

[0001] The utility model relates to the technical field of optical element assembly, in particular to a jig for assembling optical elements. Background Art

[0002] Optical elements are optical parts, the basic components of optical systems. Most optical parts play the role of imaging, such as lenses, prisms, and reflectors. In addition, there are some parts that play the role of light splitting, image transmission, and filtering in optical systems, such as reticles, filters, gratings, and optical fiber parts. As a type of optical element, filters are widely used in camera lenses.

[0003] Existing camera lenses generally include a lens barrel and a lens. The assembly of the lens barrel and the lens is generally performed by first fixing the lens barrel with a supporting jig, and then manually docking the lens with glue applied to the lens barrel to complete the assembly process. However, after the assembly is completed, the existing jig lacks a post-assembly firmness test and requires subsequent firmness testing, which is not conducive to use. On the other hand, during the existing manual assembly process, the lens lacks support when entering the lens barrel, which can easily cause the lens to flip over, affecting subsequent assembly.

[0004] A Chinese patent discloses a jig for assembling optical components (authorization announcement number CN210573038U). This patented technology places the lens barrel on the upper part of the placement slot, and turns on two sets of electric push rods through an electric push rod switch. The operation of the two sets of electric push rods drives the limit blocks and silicone pads to move, thereby fixing the lens barrel between the limit blocks. The lens coated with glue is manually placed on the upper part of the support plate, so that the lens is inside the lens barrel. Then the electric cylinder is operated. The operation of the electric cylinder drives the pressure block and rubber block to move, thereby pushing the lens into the lens barrel and contacting the fixed part of the lens in the lens barrel to realize the assembly of the lens and the lens barrel. At the same time, the spring is energized and the support plate is used to support the lens to prevent the lens from flipping during movement, thereby ensuring the assembly quality of the lens and the lens barrel.

[0005] After the lens and the lens barrel are connected, the electric cylinder is reset. At this time, the energy-storing spring applies force to the support plate, and the support plate presses on the lower part of the lens. If the lens and the lens barrel are not separated, the connection between the lens and the lens barrel is firm. Otherwise, the connection is not firm. After the connection is firm, the electric push rod is reset. Under the action of the spring force, the lens and the lens barrel move upward, which facilitates the removal of the finished product after assembly.

[0006] However, it has certain disadvantages: the size of its support plate is fixed, so its contact area with the lens is also fixed. This results in that when the lens to be assembled is large, the support plate with a smaller area will not be able to support the lens stably enough, which may lead to the possibility of the lens flipping during the descent process. Utility Model Content

[0007] The purpose of the present invention is to provide a jig for assembling optical components to solve the problems raised in the above-mentioned background technology.

[0010] As a further solution of the present invention: the clamping mechanism includes an L-shaped plate, a first telescopic cylinder is installed on the surface of the L-shaped plate away from the spring, and a clamping block is installed on the telescopic end of the first telescopic cylinder.

[0011] As a further solution of the present invention: the assembly mechanism includes a support frame, a second telescopic cylinder is installed on the upper surface of the support frame, and a pressure rod is installed at the telescopic end of the second telescopic cylinder.

[0012] As a further solution of the present invention: the support rod movably passes through the assembly table, the support block is installed on the lower surface of the mounting plate, the slide plate is slidably connected to the upper surface of the mounting plate, the mounting block is located on the outside of the mounting plate, and the lower end of the mounting bolt is attached to the upper surface of the mounting plate.

[0013] As a further solution of the present invention: the L-shaped plate is installed on the upper surface of the assembly table.

[0014] As a further solution of the present invention: the lower end of the support frame is installed on the upper surface of the assembly table, and the pressure rod is opposite to the support block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model is provided with an assembly mechanism. The second telescopic cylinder in the assembly mechanism drives the pressure rod to descend, pressing the lens into the lens barrel. The support block supports the lens to prevent it from turning over. After installation, if the spring does not pop out the lens, it means that the lens is installed firmly.

[0017] 2. The utility model is provided with a bearing mechanism. By pulling or pushing one bearing rod in the bearing mechanism, the other three bearing rods can be driven to move under the drive of the arc rod and the mounting plate, thereby realizing the synchronous movement of the four bearing rods. The four bearing rods with adjustable opening range are suitable for supporting lenses of different sizes, avoiding the phenomenon that the opening range of the four bearing rods is too small and the lens is too large, resulting in the lens flipping.
