Background technique

The scope refers to the optical aiming device. Most of the ends of the scope are equipped with a focusing lens barrel. The focal length of the scope can be changed through the focusing lens barrel, so as to obtain different-definition viewing angles and images of different sizes. The focusing lens barrel usually It is assembled from an eyepiece and a lens barrel. During the production process of the eyepiece, a fixed ring that is screwed to the inner wall of the lens is usually sleeved on the outer periphery of the eyepiece, and then the eyepiece and the lens barrel are assembled to facilitate its normal use later.

During the assembly process of the existing lens barrel, workers generally need to manually assemble and assemble the lenses on the lens barrel with the aid of a suction pen, which leads to low assembly efficiency and high labor cost. For the above problems of low assembly efficiency and high labor cost, corresponding solutions are provided in the prior art. For example, the Chinese utility model patent with the publication number CN206010308U discloses an assembly mechanism applied to automatic assembly equipment for lens barrels. The lens on the lens turntable of the two-dimensional mobile platform can be automatically assembled into the lens barrel in the lens barrel plate of the linkage device through the assembly mechanism, which can greatly reduce the labor cost, and the lens barrel assembly efficiency is high.

And the above-mentioned patent also has the following problems: 1. the above-mentioned patent controls the suction pen on the suction pen seat to move by a certain displacement value through the two-dimensional mobile platform, and makes the suction pen assemble the lens into the lens barrel, during which the lens barrel It needs to be placed in the lens barrel plate in advance. The lens barrel plate cannot limit and fix the lens barrel, so it is easy to cause improper placement of the lens barrel, which will cause its position to shift, thereby affecting the assembly accuracy of the lens and lens barrel.

2. The above-mentioned patent controls the clamping claws to clamp up or down the lens tube plate by clamping the electric push rod. The clamping jaws only provide support for the lens tube plate, and cannot limit and fix the lens tube plate. Therefore, the lens tube plate is in the process of transmission. There is a lack of stability in the lens, so it is prone to tilting or falling, and it cannot ensure that the lens barrel is placed in accordance with the assembly requirements.
