[0013] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the pointed device or element must have a specific orientation or a specific orientation. The structure and operation cannot therefore be understood as a limitation of the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.
[0014] In the description of the present invention, it should be noted that the terms "installation", "connected" and "connected" should be understood in a broad sense, unless otherwise clearly specified and limited. For example, they can be fixed or detachable. Connected or integrally connected; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication between two components. For those of ordinary skill in the art, the specific meaning of the above-mentioned terms in the present invention can be understood in specific situations.
[0015] Please refer to figure 1 , figure 2. A lens cementing device provided by the present invention includes an optical center device 1, which is a common optical center device, for example, a known transmissive center device. The principle is that the light source illuminates the cross reticle through a condenser and then forms images at infinity (parallel light) through a set of lenses. The inspected lens (or lens group) arranged on the lens stage 13 converges the parallel light (imaging) At its focal point, the objective lens of the optical central instrument images this point in the field of view of the eyepiece 17. When the turntable 12 is rotated to drive the inspected lens (or lens group) to rotate, if the outer circle of the lens is different from the optical axis, the image point will jump. In the present invention, the optical center instrument has a base 11, the turntable 12 is rotatably arranged on the base 11, and the lens of the stage is fixed on the turntable 12. The concave lens of the present invention is arranged on the lens stage 13 and can be positioned. The upright column 14 is fixed on the base 11, a height adjusting device 15 is mounted on the upright column 14 in a liftable manner, and the objective lens, the lens barrel and the eyepiece 17 are arranged on the height adjusting device 15. The base 1 is provided with a light source, a condenser lens and a cross-reticle.
[0016] The lens gluing device of the present invention also includes: an injection barrel 21, which can be tilted and slidably mounted on the upright column 14, the injection barrel 21 is formed with a containing cavity for containing glue, the injection barrel 21 is provided with a A pressurizing device (not shown in the figure) for pressurizing the containing cavity 23S, the injection cylinder 21 is provided with a glue port (not shown in the figure) communicating with the containing cavity 23S, and the glue port can be A cover body (not shown in the figure) is detachably connected, and a pressure sensor (not shown in the figure) is arranged in the accommodating cavity; a plurality of glue heads 23, the upper end of the glue head 23 and the injection barrel 21 are detachable A C-shaped hose 232 is fixed in the glue outlet 23. The upper end of the C-shaped hose 232 is connected to the receiving cavity 23S, and the other end is fixed in a nozzle 233 formed at the lower end of the glue outlet 23. A peristaltic pump 232 for intermittent opening and closing of the C-shaped hose 232 is arranged outside the outer wall of the tube 232, for example. The nozzles 233 of the multiple ejection heads 23 are on a horizontal surface and above the lens stage 13; an ultraviolet light irradiation device (not shown in the figure) for irradiating the lens stage 13; a controller ( (Not shown in the figure), the controller is electrically connected with the booster device, the pressure sensor, the peristaltic pump 231 and the ultraviolet light irradiation device. The booster device, the pressure sensor, and the peristaltic pump can be electrically connected to the controller through a wire 24.
[0017] When the glue dispensing is controlled by the above-mentioned lens gluing device, the injection cylinder 21 and the glue head 23 tilt to the top of the lens carrier 13, the C-shaped hose is opened, and the glue dispensing operation is performed; after the glue dispensing operation, the glue injection The barrel 21 and the glue head 23 are retracted so as to be separated from directly above the lens carrier 13. At this time, the convex lens can be manually placed on the concave lens and the centering operation is performed. After the centering operation is completed, UV light is irradiated to cement the convex lens and the concave lens together. The lens cementing device of this embodiment has higher production efficiency.
[0018] Further, the lens gluing device further includes a fixing device 27, the fixing device 27 is installed on the column 14, a transversely arranged adapter 22 is fixed on the fixing device 27, the injection barrel 21 and the adapter 22 Form a slidable connection. In this way, it is very convenient to prevent the glue head 23 from blocking the light path.
[0019] Further, the peristaltic pump 232 can be driven by a pulse motor to open and close intermittently, and the peristaltic pump 232 is also electrically connected to the controller. In some other embodiments, the intermittent opening and closing can also be realized by other means, such as solenoid valves.
[0020] Further, the controller has an electric control box 25 and a control handle 26 installed on the electric control box 25, and the electric control box 25 is fixed on the base 11 of the optical central instrument. The booster device, the pressure sensor, and the peristaltic pump can be electrically connected to the electric control box through a wire 24. This is very convenient for operators to operate.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand: It is still possible to modify the technical solutions described in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention. range.
