Neglected loading detection mechanism for parts

Abstract

The invention relates to a neglected loading detection mechanism for parts. The mechanism comprises a bracket seat, a push rod and a proximity switch. The bracket seat comprises a base plate and a vertical plate. The push rod is vertically threaded in an installation hole in the base plate and can freely move in the vertical direction. The proximity switch is installed on the vertical plate of the bracket seat. A magnetic part on the upper part of the push rod after moving upwards is opposite to the proximity switch in a detection area. The peripheral dimension of the magnetic part is greater than that of the installation hole of the base plate. Position of the push rod is controlled through a part to be detected, so that the magnetic part on the upper part of the push rod controls the proximity switch to switch on and off, therefore, not only can parts made of metal materials be detected, but also parts made of non-metal materials can be detected. Neglected loading detection of parts of a product is realized, and the mechanism is simple in structure and small in occupied space, and can be installed and used in a smaller space. The mechanism is low in manufacturing cost, the using and maintenance cost is also greatly lowered. The mechanism is strong in adaptability and can meet modern production demand.

Description

technical field [0001] The invention relates to a detection mechanism for parts missing, which belongs to the technical field of testing products for missing parts. Background technique [0002] Regardless of whether it is a mechanical product or an electronic product, the parts of the product need to be connected by various and multiple fasteners, especially on the assembly line with a fast assembly process, sometimes there will be fewer parts such as fastening Parts and other phenomena, resulting in unreliable connection of parts and affecting product quality. Usually on the product assembly line, the operator's observation and experience are used to judge whether a part is missing or not, and manual visual inspection will increase the labor intensity of the operator on the one hand, and on the other hand, the accuracy rate is not high, which cannot meet the existing production requirements. .

[0002] Regardless of whether it is a mechanical product or an electronic product, the parts of the product need to be connected by various and multiple fasteners, especially on the assembly line with a fast assembly process, sometimes there will be fewer parts such as fastening Parts and other phenomena, resulting in unreliable connection of parts and affecting product quality

Usually on the product assembly line, the operator's observation and experience are used to judge whether a part is missing or not, and manual visual inspection will increase the labor intensity of the operator on the one hand, and on the other hand, the accuracy rate is not high, which cannot meet the existing production requirements.

At present, there is a missing installation detection process at the product assembly site or after the product is assembled, and the magnetic proximity switch controls the closed state of the switch through magnetic induction, and has the advantages of reliable operation, long life, low power consumption, high reset positioning accuracy, and high operating frequency. As well as adapting to harsh working environments and other advantages, it is used for product missing detection. When the product passes through the detection area of ​​the magnetic proximity switch, whether the magnetic proximity switch outputs a signal to determine whether the part is present or not, but most of the signal switches are relatively large in size. It cannot be installed in a small space, and it is difficult to achieve the ideal signal requirements

Furthermore, the magnetic proximity signal switch provides a signal through the magnetism of the part under test in the detection area, and can only be used to detect parts of metal materials.

At present, more and more parts are made of non-metallic materials, and many fasteners are also made of non-metallic materials. Therefore, the current leakage detection mechanism using magnetic proximity switches cannot detect parts of non-metallic materials.

For example, if a color-resolving optical fiber switch or a CCD imaging system is used to detect parts made of non-metallic materials, the structure of the entire detection system is complex, and the cost of use and maintenance is high.
