Projection lamp filament and lamp cup focusing and glue injecting device based on mold positioning and method of device

Abstract

The invention discloses a projection lamp filament and lamp cup focusing and glue injecting device based on mold positioning and an application method of the device. The projection lamp filament and lamp cup focusing and glue injecting device comprises a worktable, a lamp cup, an automatic lamp cup positioning device, a lamp filament, an automatic lamp filament positioning device, a calibration lamp source device, a glue injecting device, a PLC (programmable logic controller), a four-quadrant detector, a signal processor, a display, a lamp cup clamping manipulator and a lamp filament clamping manipulator. The projection lamp filament and lamp cup focusing and glue injecting device and the application method are applicable to focusing and glue injecting of lamp cups and lamp filaments which are produced in a batch, the requirement on consistency of the lamp cups and the lamp filaments is high, and the requirements on processing precision and control precision of the device are also high. After a light path is calibrated, the lamp cup is fixed to the automatic lamp cup positioning device, the lamp filament is positioned to the automatic lamp filament positioning device, and glue is injected by the aid of the glue injecting device and is dried. By the aid of the projection lamp filament and lamp cup focusing and glue injecting device and the application method, multiple lamp filaments and multiple lamp cups can be simultaneously focused and injected with the glue on the same worktable at one step, and are clamped and placed conveniently, production efficiency of focusing and glue injecting procedures is greatly improved, production cost is lowered, and the projection lamp filament and lamp cup focusing and glue injecting device and the application method are applicable to automatic production.

Description

technical field [0001] The invention relates to the field of projectors, in particular to a projection wick lamp cup focusing glue injection device based on mold positioning and a method thereof. Background technique [0002] The lighting device in the projector, that is, the projection lamp is mainly composed of a wick and a lamp cup. The quality of the projection lamp is closely related to the overall picture performance of the projector. The light emitted by the wick is reflected by the inner surface of the lamp cup to obtain a beam, and the position of the wick in the lamp cup has a great influence on the light intensity, parallelism and uniformity of the formed beam. ", the process of controlling the position of the wick in the lamp cup is called focusing glue injection. [0003] The current focusing and glue injection positioning is based on the two ends of the wick, as shown in the patent with the publication number CN102305988A. However, due to the objective limitat...
