Description

Technical Field

[0001] The utility model relates to the technical field of lens production, in particular to an adsorption device and lens assembly equipment. Background Art

[0002] During the lens assembly production process, the lens components need to be assembled in a preset sequence of steps. There are two precision requirements for the assembly accuracy of the lens components. The first is the relative parallelism requirement between the lens components and the supporting base, and the second is the assembly coaxiality requirement between the lens components, such as the coaxiality requirement between the lens and the lens barrel. In order to prevent the lens from being damaged by the robot, a suction cup is usually set at the execution end of the robot to absorb the lens in the form of vacuum adsorption.

[0003] However, different lenses are arranged on a tray or a conveyor belt. When the execution end of the robot moves to the top of the tray or the conveyor belt to adsorb the lenses, there may be a deviation in the position where the suction cup adsorbs the lenses, that is, the central axis of the lens and the central axis of the suction cup may not be coaxial, and the path that the robot drives the suction cup to move is calculated in advance. After the suction cup moves to the top of the lens barrel, when the central axis of the suction cup is coaxial with the central axis of the lens barrel, it means that the lens and the lens barrel are not coaxial, and the coaxiality between the lens and the lens barrel does not meet the requirements.

[0004] Therefore, there is an urgent need for an adsorption device and a lens assembly device to solve the above problems. Utility Model Content

[0041] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] like Figures 1 to 5 As shown, the present embodiment provides an adsorption device, which includes a mounting assembly 1, a driving member 2, a suction rod 3 and a shaping jig 4; the driving member 2 is mounted on the mounting assembly 1; the suction rod 3 is mounted on the output end of the driving member 2 and is connected to the vacuum system, the suction rod 3 is used to adsorb the lens component 100, and the driving member 2 is used to drive the suction rod 3 to drive the lens component 100 to move closer to or away from the lens main barrel 200; the shaping jig 4 is mounted on the mounting assembly 1, and the shaping jig 4 is provided with a first through hole, and the side of the first through hole facing the lens main barrel 200 is set as a bell mouth 41, and the suction rod 3 passes through the first through hole, and when the lens component 100 abuts against the bell mouth 41, the bell mouth 41 can shape the lens component 100 so that the lens component 100 is coaxial with the suction rod 3.

[0043] Specifically, when the lens component 100 needs to be adsorbed, the driving member 2 drives the suction rod 3 to pass through the first through hole and approach the lens component 100. After the suction rod 3 adsorbs the lens component 100, the driving member 2 drives the suction rod 3 to lift the lens component 100, so that the peripheral edge of the lens component 100 abuts against the inner wall of the bell mouth 41. If the central axis of the lens component 100 is not coaxial with the central axis of the suction rod 3, the inner wall of the bell mouth 41 generates a radial force on the peripheral edge of the lens component 100 during the process of the suction rod 3 lifting the lens component 100, so that the lens component 100 is offset in the radial direction, and finally the central axis of the lens component 100 is coaxial with the central axis of the suction rod 3. Then the driving member 2 installs the lens component 100 into the lens main barrel 200 through the suction rod 3. In this embodiment, the bell mouth 41 of the shaping jig 4 is used to shape the lens component 100 so that the lens component 100 and the suction rod 3 are coaxial. This ensures that the suction rod 3 can accurately load the lens component 100 into the lens main barrel 200 and ensures the coaxiality of the lens component 100 and the lens main barrel 200.

When the lens component 100 abuts against the inner wall of the bell mouth 41 of the shaping jig 4, if the lens component 100 is not coaxial with the first through hole of the shaping jig 4, a radial interaction force is generated between the lens component 100 and the shaping jig 4. Therefore, in this embodiment, the shaping jig 4 is tightly fitted in the second through hole to limit the displacement of the shaping jig 4 in the radial direction, thereby preventing the shaping jig 4 from deviating in the radial direction, thereby ensuring that the lens component 100 can be radially deviated to a position facing the first through hole after being subjected to the radial force.

[0048] Optionally, the outer wall of the mounting assembly 1 is provided with a first threaded hole 111, the first threaded hole 111 is connected to the second through hole, the central axis of the first threaded hole 111 is perpendicular to the central axis of the second through hole, and the threaded fastener can lock the shaping jig 4 in the second through hole after passing through the first threaded hole 111, so as to prevent the shaping jig 4 from rotating in the second through hole. When the shaping jig 4 needs to be replaced, the threaded fastener is unscrewed, and the shaping jig 4 can be taken out from the second through hole. When the threaded fastener locks the shaping jig 4 in the second through hole, the shaping jig 4 cannot be separated from the second through hole even if the shaping jig 4 is subjected to an axially upward force from the lens component 100.

[0049] Optionally, the mounting assembly 1 includes a positioning seat 11 and a bearing seat 12 , the positioning seat 11 is detachably mounted on the bearing seat 12 , the second through hole is opened in the positioning seat 11 , and the plastic surgery jig 4 is placed on the positioning seat 11 .

[0052] After the height position of the lens component 100 is changed, the height position of the suction rod 3 is adapted to the height position of the lens component 100 by adjusting the installation height of the support seat 13 on the bearing seat 12 .

When the suction rod 3 adsorbs the lens, the end edge of the suction rod 3 tightly abuts against the peripheral edge of the lens.
