Description

Lens kneading device

The present invention relates to a lens kneading device, in particular to a lens kneading device that can achieve uniform application of viscose in an automated manner.

In the process of making spectacle lenses or photographic lens lenses, it is sometimes necessary to bond two lenses together with glue to form a composite optical element. During the bonding process, the glue needs to be spread evenly on the intersection of the two lenses. On the interface, there must be no air bubbles remaining in the glue, otherwise the path of the light will be deflected and reduce its optical effect. In order to achieve the above purpose, the two lenses are manually kneaded in the past. In this way, all parts of the interface of the two lenses can be squeezed, so that the adhesive can be evenly applied to the interface of the two lenses and the adhesive can be discharged. The air bubbles in the glue, but manual methods are not only time-consuming and inefficient, but also easily cause occupational injuries to workers' hands.

In order to solve the above inconvenience, some companies have developed an automated device for lens rubber kneading, such as Patent WO 95/13904, which first compacts the upper and lower lenses, and then drives the upper lens to rotate concentrically. However, in the use of a concentric rotation method, the adhesive can only be diffused from the coating area, and the adhesive cannot be evenly spread on the interface between the two lenses, nor can the bubbles in the adhesive be completely discharged .

In addition, for example, the automatic rubber kneading device disclosed in CN 208737111 patent case, the device compacts the upper and lower lenses, and then drives the upper lens to move in a linear reciprocating direction relative to the lower lens. The junction of the lower lens is a circumferential surface, so this single direction of reciprocating rubber kneading method will cause the upper and lower lens to be squeezed on both sides of the suspension direction, and it will also prevent the glue from being wiped. There are problems of uniformity and the inability to completely expel the bubbles in the viscose.

In view of this, how to solve the above-mentioned problems is the primary problem to be solved by the present invention.

Please continue to refer to Figs. 4-7. When the present invention composed of the above-mentioned structure actually performs the lens rubber kneading operation, the first suction unit 35 and the second suction unit are first used to inhale the lens first. The air in the hole 33 and the second suction hole 43 is drawn out to form a vacuum state, so that the first lens 36 and the second lens 46 can be adsorbed to the first lens fixing portion 31 and the second lens fixing portion 41, respectively Middle; then apply glue on the upper surface of the second lens 46, at this time the central axis of the first lens 36 and the central axis of the second lens 46 are located on the axis L, and drive the first sliding member 61 drives the active rod 10 to move down along the Z axis, and at the same time, pushes up the lens placement mold 40 through the pneumatic cylinder 54 until the lower surface of the first lens 36 and the upper surface of the second lens 46 adhere to each other Together. Then, the drive group 60 can be controlled to drive the driving rod 10 in a spiral shape around the axis L through the drive sequence and displacement path of the drive group 60 preset by a controller (such as a Programmable Logic Controller, PLC ). The gradual trajectory (shown in the direction of the dashed arrow in Figure 6) moves. In detail, by presetting the displacement time course of the second sliding member 63 and the third sliding member 65 of the driving group 60 to drive the active The rod 10 is displaced toward the X axis and the Y axis at the same time, and the active rod 10 can be driven to move around the axis L in a spirally expanding track.

When the active rod 10 is driven by the driving group 60 to move in the spiral gradual trajectory, since the upper end of the linkage rod 20 is pivotally connected to the bottom end of the active rod 10 by the universal joint structure 11, it is located at The first lens 34 at the lower end of the linkage rod 20 is relatively abutted on the second lens 46, so that the active rod 10 is pivoted at the bottom end of the active rod 10 when the active rod 10 moves in the spiral gradual trajectory. 20 will also be pulled by the active rod 10, and can also be pivotally offset in a spirally expanding trajectory around the axis L, thereby making the first lens attracted by the lens suction cup 30 located at the lower end of the linkage rod 20 36.
