Magnifying lens device used for lamp detector and detection method

Abstract

The invention provides a magnifying lens device used for a lamp detector and a detection method. The device comprises a rotary shaft, a height adjuster, a magnifying lens, a front-back propeller and a fixing bracket, wherein the front-back propeller is arranged on the outer side of a conveyor belt of the lamp detector; the fixing bracket is mounted on the front-back propeller; the height adjuster is vertical to the conveyor belt; one end of the height adjuster is connected with the fixing bracket and the other end of the height adjuster is movably connected with the rotary shaft; and the magnifying lens is fixed on the rotary shaft. According to the magnifying lens device used for the lamp detector and the detection method provided by the invention, the omission ration is effectively reduced, the detection accuracy of unqualified products is improved and the product loss is reduced; and the method is simple to operate and the improvement of equipment is convenient, so that workers can be rapidly trained for the post.

Description

technical field [0001] The invention relates to a magnifying glass device, in particular to a magnifying glass device and a detection method for lamp inspection. Background technique [0002] Light inspection is one of the necessary filling process steps in many liquid food filling production lines, and some are even critical control points in the food safety system. Its role is to control the inherent quality of bottled medicines or beverages, including empty bottle inspection and finished product inspection. [0003] Using the light inspection equipment on the original filling line, the following problems were found in the daily monitoring work: [0004] 1. Due to the small contact area between the eyes, the bottle and the background light, and the filling production speed of most modern production lines is at least 10,000 bottles per hour, the inspection time is short and the contact area is small, which is easy to cause inspection The eyes and vision of the personnel a...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the small contact area between the eyes, the bottle and the background light, and the filling production speed of most modern production lines is at least 10,000 bottles per hour, the inspection time is short and the contact area is small, which is easy to cause inspection Personnel's eye vision is fatigued quickly, which is easy to cause missed inspections, and several groups of personnel need to be frequently exchanged and rested

[0005] 2. The distance and height cannot be adjusted, and can only be adjusted by the post personnel, which may also easily cause premature fatigue of the personnel

[0006] 3. It is difficult to distinguish bottle trachoma, cork slag, flying insects and other impurities in actual operation. From the perspective of product quality, trachoma on the bottle does not affect product quality and is a qualified product; while for bottles sealed with cork For wine, the national standard stipulates that a small amount of cork residue is allowed, which also belongs to the category of qualified products; flying insects and other impurities are unqualified products and must be sorted out.

However, it is difficult to distinguish when the equipment is inspected by ordinary methods, so all must be picked out manually. According to preliminary statistics, among all the unqualified products manually picked out, the qualified products belonging to trachoma or a small amount of cork residue accounted for more than 90%. A small number of products are substandard products, but because they cannot be accurately identified, uncertainty is increased, resulting in great loss, unnecessary waste, and increased production costs

[0007] 4. Pre-job training for new employees is more difficult. New employees need to be led by a master for a period of time and have accumulated enough experience before they can work independently

[0008] Therefore, the light inspection process is a key control point of food safety, but it is not easy to control due to various factors
