Description

Technical Field

[0001] This invention relates to the field of lens technology, and in particular to a lens barrel assembly device and assembly method. Background Technology

[0002] Lens assembly is a technology that demands high precision in component machining and assembly processes. The general process involves vertically placing the lens assembly into the lens barrel and securing it with roller screws from the side. The assembly must be tilted within specifications after securing and slide smoothly as the lens barrel rotates. This requires a matching and efficient assembly device to meet the technical requirements of the assembly process and ensure the lens's image quality. Traditionally, for stability, lens assembly uses horizontal roller screws to secure the assembly within the lens barrel. However, traditional vertical jigs for lens barrel assembly are generally only suitable for fixed lens models and can only be used with traditional manual screwdrivers for horizontal securing. This is unsuitable for mass production of lens barrels, resulting in poor assembly precision and low production efficiency. Summary of the Invention

[0050] The following two embodiments illustrate the lens barrel assembly method of this application.

[0051] Example 1:

[0052] Reference Figure 1 and Figure 2This invention discloses a lens barrel assembly device and method for installing a type A lens barrel 501. The lens barrel assembly device includes a main body, an adsorption component, a pressing component, and a pressure adjusting component 300. The main body includes a frame and a rotating component. The rotating component includes a rotating shaft 107 and a roller 101. The type A lens barrel 501 shaft 104 is mounted on the rotating shaft 107. The rotating shaft 107 is fitted into the roller 101 and connected to the bearing seat 103 by a nut. The type A lens barrel 501 shaft 104 is locked onto the rotating shaft 107 by a through-hole bolt 105. The type A lens barrel 500 is adsorbed onto the type A lens barrel 501 shaft 104, and then the type A lens barrel 501 is fitted onto the type A lens barrel 501 shaft 104. The roller 101 is provided with a positioning pin for clamping the type A lens barrel 501. Rotating the roller 101 can achieve 360° clockwise and counterclockwise rotation. The pressure regulating component 300 is bolted to the base plate 100. Two pressure regulating valves are connected to a first pneumatic switch and a second pneumatic switch, respectively. The first and second pneumatic switches control the adsorption component and the pressing component, respectively. The first pneumatic switch has an air circuit connected to a silencer 201, which in turn connects to a rotary joint to achieve adsorption of the group. The second pneumatic switch has an air circuit connected to a dual-axis cylinder, which drives the pressure plate 401 to press against the end face of the Class A lens barrel 501, achieving a pressing effect on the Class A lens barrel 501. The pressure plate 401, along with the roller 101, rotates the Class A lens barrel 501 and the group together. A ball-head pin is locked to the base plate 100 to fix the rotation angle of the roller 101. Adjusting the position of the lens barrel and the group by rotating the component facilitates locking the group and improves assembly efficiency.

[0053] Example 2:

[0054] Reference Figure 1 and Figure 2This invention discloses a lens barrel group assembly device and method. After the A-type lens barrel 501 is assembled, the B-type lens barrel 601 is installed. First, the through-hole bolt 105 is removed, the A-type lens barrel 501 shaft 104 is taken off, and then the B-type lens barrel 601 shaft 106 is replaced. The B-type lens barrel 601 shaft 106 is then locked with the through-hole bolt 105, thus realizing the group adsorption assembly of the B-type lens barrel 601. The B-type group 600 is adsorbed onto the B-type lens barrel 601 shaft 106, and then the B-type lens barrel 601 is fitted onto the B-type lens barrel 601 shaft 106. The roller 101 is provided with a positioning pin for clamping the B-type lens barrel 601. Rotating the roller 101 can achieve 360° clockwise and counterclockwise rotation. The pressure regulating component 300 is bolted to the base plate 100. Two pressure regulating valves are connected to a first pneumatic switch and a second pneumatic switch, respectively. The first and second pneumatic switches control the adsorption component and the pressing component, respectively. The first pneumatic switch has an air circuit connected to a silencer 201, which in turn connects to a rotary joint to achieve adsorption of the group. The second pneumatic switch has an air circuit connected to a dual-axis cylinder, which drives the pressure plate 401 to press against the end face of the B-type lens barrel 601, achieving a pressing effect. The pressure plate 401, along with the roller 101, rotates the B-type lens barrel 601 and the group together. A ball-head pin is locked to the base plate 100 to fix the rotation angle of the roller 101. Adjusting the position of the lens barrel and the group by rotating the component facilitates locking the group and improves assembly efficiency. The rotating shaft 107 is detachably mounted on the frame. The rotating shaft 107 is used to install the lens barrel shaft, and the roller 101 is used to install the lens barrel. By replacing the lens barrel shaft, it is possible to install and adapt to different lens barrels and groups, which is suitable for group assembly of different lens barrels and improves versatility.
