Abstract

The invention discloses an inner hole size detection device, a detection assembly line and a detection method. The inner hole size detection device comprises an operation table; a placing assembly which is arranged on the operation table; a clamping assembly which is arranged on the placing assembly; a first positioning block which is arranged on the placing assembly and is opposite to the clamping assembly; a contact type sensor which is arranged on the operation table, wherein the contact end of the contact type sensor penetrates through the first positioning block and abuts against the clamping assembly during product detection, and the displacement amount during abutting is recorded; a controller which is electrically connected with the contact type sensor and used for receiving the first displacement recorded by the contact type sensor when no product is placed on the placing assembly and the second displacement recorded by the contact type sensor when the product is placed, calculating the wall thickness of the inner hole according to the first displacement and the second displacement, and determining whether the size of the inner hole of the product is qualified or not according to the wall thickness. According to the invention, the problem of three damages caused by manual go-no go gauge detection in the production process is solved.

Description

technical field [0001] The invention relates to the technical field of part detection, in particular to an inner hole size detection device, a detection assembly line and a detection method. Background technique [0002] As mobile phones have entered the era of comprehensive development, mobile phones have become an indispensable electronic product in many people's lives. Most of the existing mobile phones choose to insert the earphone hole in the extremely cramped area of ​​the middle frame. At the same time, the earphone also has a certain amount of requirements for the internal space of the mobile phone. Whether the size of the inner hole exceeds the maximum or minimum size, so as to judge whether the tested earphone is qualified. However, when using the go-no-go gauge for detection, it is very easy to scratch the inner wall of the earphone hole, resulting in the original qualified product becoming a defective product. Contents of the invention [0003] The invention ...
