Embodiment Construction

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention relates to a length detection device used for detecting length of LED (light emitting diode) terminal strips. The length detection device comprises a conveying line, a detection instrument, a retaining mechanism and a control device. The detection instrument comprises a fixing mechanism, a first detection optical fiber, a second detection optical fiber and a third detection optical fiber. By taking the third detection optical fiber as a benchmark, a distance between the first detection optical fiber and the third detection optical fiber is larger than that between the second detection optical fiber and the third detection optical fiber; the distance between the second detection optical fiber and the third detection optical fiber corresponds to a preset minimum length of a qualified LED terminals trip; the distance between the first detection optical fiber and the third detection optical fiber corresponds to a preset maximal length of the qualified LED terminals trip. The length detection device has advantages that by the three detection optical fibers which replace manual operations for product length detection, detection efficiency and precision are improved; due to arrangement of the retaining mechanism and the control device, unqualified products can be intercepted while alarming is performed, and alertness of operators is improved.

Description

technical field [0001] The invention relates to the field of processing and detection of LED accessories, in particular to a length detection device for detection of LED terminal strips. Background technique [0002] With the rapid development of the economy, the LED industry has also entered a period of rapid development. In the production process, there are more and more spare parts for LED terminal strip assembly, and the required processing precision is getting higher and higher. It is not in line with the development of the modern mobile phone industry to complete a certain process only by manual operation. [0003] In the traditional technology, the LED terminal strips are preliminarily cut by a cutting punch, and then the length of the cut LED terminal strips is manually inspected. Usually, tools such as calipers or rulers are used for inspection. After the final inspection is qualified, the next process is carried out. The above-mentioned detection process only reli...
