Device for automatically positioning projection lamp wick in lamp cup and method for positioning same

Abstract

The invention relates to a device for automatically positioning a projection lamp wick in a lamp cup and a method for positioning the same, which belong to the field of industrial automation control and are applied to achieving safe, effective and highly accordant assembly of the lamp wick and the lamp cup to satisfy requirements on mass production with the lowest cost. The device mainly comprises the following three parts: a vision system, an image processing system and a motion control system, wherein the vision system acquires images projected on a screen (7) by a projection lamp and transmits the images to the image processing system; the image processing system processes the data acquired by the vision system, and compares and analyzes the data with empirical data in a database to get whether the position of the current lamp wick (4) is optimized relative to the lamp cup (5) and generate motion control parameters; and the motion control system adjusts the position of the lamp wick (4) according to the motion control parameters. Through the positioning device and the method, safe operations are achieved, the production quality and the efficiency of products are improved, and energy sources are saved.

Description

Technical field [0001] The invention belongs to the field of industrial automation control, covering the fields of machine vision, computer image processing, automatic control, etc., and particularly relates to a device and method capable of automatically positioning a wick in a lamp cup during a projection lamp assembly process. Background technique [0002] A projection lamp is mainly composed of a lamp cup, a wick (AC and DC ultra-high-pressure mercury lamps, metal halide lamps and other high-brightness projection wicks) and other auxiliary parts. Among them, the position of the wick relative to the lamp cup is the focus of the projection lamp assembly, which directly determines the output, consistency and service life of the projection lamp. [0003] In the existing projection lamp assembly process, human vision and subjective judgment are mainly used to manually find the best position of the wick in the lamp cup. Reference figure 1 , The general assembly steps include: [0...

AI Technical Summary

Problems solved by technology

Most of the current projection lamp power is 200 watts or even higher. Since the lamp must be ignited and stabilized before adjustment, the power consumption is high.

[0013] 2. Affected by human factors: due to the high-intensity light emitted by the projection lamp, the color temperature is about 8500K, which makes the human eyes easily tired, so it is difficult to maintain consistency in recognition and judgment. For large-scale production, product consistency and stability Difficult to guarantee

[0014] 3. Poor safety: projection lamps inevitably have a certain early failure rate

The splash of high pressure (200 atmospheres) and high temperature (thousands of degrees) debris generated at this time is a major hidden danger to the safety of operators.
