specific Embodiment approach 1

[0034] Specific implementation mode 1. Combination figure 1 As shown, the present invention provides a method for automatic sorting of aluminum and aluminum alloy thin-walled pipes based on eddy current detection, including:

[0035] The eddy current probe 11 and the photoelectric switch 20 of the flaw detector 10 are arranged on the conveying equipment of the thin-walled pipe,

[0036] The eddy current probe 11 is arranged in the detection area of ​​the conveying equipment, and is used to detect the quality information of the thin-walled pipe in the detection area; the photoelectric switch 20 is used to determine the time when the thin-walled pipe enters and leaves the detection area;

[0037] Described automatic sorting method comprises:

[0038] The flaw detector 10 transmits the quality signal obtained by the eddy current probe 11 to the programmable logic controller 30;

[0039] The photoelectric switch 20 transmits the time when the thin-walled pipe enters and leaves t...

specific Embodiment

[0059] Specific embodiment: first debug the instrument, set the optimal flaw detection parameters of the flaw detector 10, so as to be able to accurately detect aluminum and aluminum alloy thin-walled pipes, and accurately mark the natural flaws that exceed the corresponding standards, and for qualified products and Unqualified products are accurately sorted.

[0060] 1) Make comparison sample tubes according to the corresponding standards, and use the comparison sample tubes to debug instruments and equipment until the best flaw detection parameters, and select appropriate pneumatic control devices, photoelectric switches, cylinders, etc.;

[0061] 2) Make sure that the marking device is reliable in action, using ink marks as identifiable marks, and marking the position of natural damage exceeding the standard is accurate;

[0062] 3) Confirm that the action of the sorting device for qualified and unqualified products is accurate and reliable;

[0063] After the above adjust...

Abstract

The invention discloses an aluminum and aluminum alloy thin-wall pipe automatic sorting method based on eddy current testing, belongs to the technical field of thin-wall pipe automatic flaw detection,and aims at the problems that the existing aluminum and aluminum alloy thin-wall pipes are subjected to quality detection in a manual mode, efficiency is low and reliability is poor. The method comprises the following steps: a flaw detector transmits a quality signal obtained by an eddy current probe and the time of entering and leaving a detection area of the thin-wall pipe obtained by a photoelectric switch to a programmable logic controller; the programmable logic controller processes an input signal and firstly divides the thin-wall pipe into a defect-free pipe and a pipe comprising a defect part; then a defect position marking instruction to the pipe comprising the defect part is outputted and an ink-jet printer is controlled to mark the defect part of the pipe comprising the defectpart; and finally a sorting control instruction is outputted and the air cylinder is controlled to sort the defect-free pipes and the pipes subjected to defect marking to a qualified area or a defectarea. The method is used for automatic sorting of the aluminum and aluminum alloy thin-wall pipes.

Description

technical field [0001] The invention relates to an automatic sorting method for aluminum and aluminum alloy thin-walled pipes based on eddy current detection, and belongs to the technical field of automatic flaw detection for thin-walled pipes. Background technique [0002] Aluminum and aluminum alloy thin-walled pipes are widely used due to their advantages of light weight and good corrosion resistance, especially for high-end products. In order to better apply the performance of the thin-walled pipe, it is particularly important to perform performance testing. [0003] At present, the quality inspection of aluminum and aluminum alloy thin-walled pipes is mainly manual. On the one hand, the efficiency of manual inspection is low. Meet the high-efficiency and non-destructive testing accuracy requirements on the production line. Contents of the invention [0004] Aiming at the problem that the existing aluminum and aluminum alloy thin-walled pipes are manually inspected f...
