Manual light inspection machine

Abstract

The invention discloses a manual light inspection machine capable of prompting a light inspection person to place an inspected matter at an optimal observation position. The manual light inspection machine comprises a frame, controllers and an alarming device, wherein a light inspection operating platform and a machine awning are arranged on the frame; a light source is arranged in the machine awning; a plurality of brackets are arranged on the platform board of the light inspection operating platform; a base is arranged on each bracket; a matter position detecting switch is arranged on each base; and the matter position detecting switches and the alarming device are electrically connected with the controllers respectively. By arranging the matter position detecting switch on each base, whether an inspected matter placed on the base is placed in position or not can be detected, if the inspected matter is not placed at the optimal observation position, the matter position detecting switch transmits a detected signal to the controller, and the controller transmits an alarming signal to the alarming device to prompt the light inspection person to place the inspected matter at the optimal observation position, so that a final light inspection result is more accurate and more reliable. The manual light inspection machine is suitable to be popularized and applied in the field of light inspection equipment.

Description

technical field [0001] The invention relates to the field of light inspection equipment, in particular to a manual light inspection machine. Background technique [0002] "Chinese Pharmacopoeia" stipulates that "the products should be inspected one by one with appropriate methods before leaving the factory and the unqualified products should be eliminated at the same time." . At present, there are two types of light inspection equipment used: automatic light inspection machine and manual light inspection machine. For automatic light inspection machine, although automatic light inspection machine has the advantages of fast speed, high sensitivity and continuous detection, it is applicable The product range is small, and the structure of the equipment is complex and the cost is high. Therefore, in the pharmaceutical production industry, in order to save costs, the automatic light inspection machine is generally not used to detect the product, but the artificial light inspecti...

AI Technical Summary

Problems solved by technology

[0003] First of all, when placing the inspected object on the base, whether the inspected object is placed in the best observation position can only be judged by the light inspectors themselves, and the judgment results of different light inspectors are also different. Different placement positions will lead to different final light inspection results, and the reliability of the light inspection results is poor

[0004] Secondly, according to the provisions of the Pharmacopoeia, during the inspection process, the light intensity of the light source of the artificial light inspection machine must be kept at 1000-4000lx to ensure the quality of the light inspection. However, the existing artificial light inspection machines do not have corresponding light intensity detection devices. During the light inspection process, once the light intensity changes and exceeds the specified light intensity range, the light inspection personnel cannot find out in time, and the quality of the light inspection cannot be guaranteed.

[0005] Furthermore, when different light inspectors use artificial light inspection machines to carry out light inspection on the inspected object, the visual distance and viewing angle between the light inspector and the inspected object are different, which makes the judgment result of the light inspection It may be different. The existing manual light inspection machine does not have a corresponding viewing distance detection device, and it is impossible to accurately locate the position of the light inspection personnel, so that the light inspection personnel cannot be in the best observation position, and thus make the final light inspection There are inconsistencies in the results, and the reliability of the light inspection results is poor

[0006] In addition, when the light inspectors visually inspect the inspected object, there are strict regulations on the inspection time of the inspected object, and the existing manual light inspection machine does not have a corresponding time control device. The inspection time required for each surface of the inspection object cannot be precisely controlled. If the inspection time is too short, it will cause false or missed inspections, and the quality of light inspection cannot be guaranteed. Moreover, the working hours of light inspection personnel cannot be effectively controlled. , Light inspectors are prone to fatigue after a long time of work, the ability to respond is reduced, and false detection or missed detection is prone to occur

[0007] Finally, the brackets of existing manual light inspection machines are generally fixed on the worktable, and the position of the brackets cannot be adjusted according to the conditions of different light inspection personnel, which is very inconvenient to use
