Brief Description of the Drawings

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] Figure 1 It is a system block diagram of the present invention. Detailed Embodiments

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1

[0038] The present invention is a high-strength corrosion-resistant alloy wire, including raw materials in the following weight percentages: Si 10%, Cr 0.3%, Er 0.2%, and the balance is Al;

[0039] Embodiment 2

[0040] Based on the above-mentioned Embodiment 1, a production process of a high-strength corrosion-resistant alloy wire according to the present invention includes the following steps:

[0041] Step 1: Draw the aluminum alloy rod into an aluminum-magnesium alloy wire;

[0042] Step 2: Place the aluminum alloy wire into an immersion tank filled with a film coating treatment liquid for impregnation, film scraping, and drying to obtain a high-strength corrosion-resistant alloy wire;

[0043] Among them, a film coating system is provided at the discharge port of the immersion tank, referring to Figure 1 ;

[0044] The film coating system includes a scraper for scraping off the excess glue on the surface of the alloy wire, and a collection point for detecting damage to the alloy wire. Among them, n collection points are arranged in a ring, n is a positive integer and an even number. Preferably, n is 4; A vision camera is arranged at each collection point, and the alloy wire is imaged through the vision camera; By arranging multiple collection points in a ring array, the alloy wire can be comprehensively collected and analyzed;

[0045] The acquisition module acquires the image of the alloy wire through the vision camera to obtain the abnormal area on the surface of the alloy wire in the image;

[0046] The specific working process of the acquisition module is as follows:

[0047] Step 1: Preset the acquisition length of the alloy wire, marked as L, and obtain n acquisition pictures of the alloy wire with a length of L;

[0048] Step 2: Obtain the abnormal area in each acquisition picture and mark it as Sm n ; Among them, the abnormal area includes the area with scratches and burrs on the surface of the alloy wire;

[0049] In the present invention, through the acquisition module, during the scraping process of the alloy wire film coating, whether there is a phenomenon that the alloy wire has burrs or scratches on its surface due to the action of the scraper on the surface of the alloy wire, thereby affecting the quality of the alloy wire preparation;

[0050] In this way, by taking the abnormal area of the alloy wire as the object, the film coating process of the alloy wire is monitored to improve the production quality of the alloy wire;

[0051] The analysis module receives the abnormal area Sm of the alloy wire from the acquisition module n , and constructs a set A {Sm1, Sm2,..., Sm n} in the order of clockwise arrangement of the collection points, and sorts and analyzes the subsets in the set A to judge whether the alloy wire after scraping glue is qualified;

[0052] The specific work of the analysis module is as follows:

[0053] Step 1: Obtain the subsets in set A {Sm1, Sm2,..., Sm n}, and calculate the total different area value ZSm through the formula , and calculate the different area difference CSm through the formula ;

[0054] Step 2: Obtain the total different area value ZSm and the different area difference CSm, and calculate the alloy wire difference value ZY through the formula , where a1 and a2 are both proportionality coefficients, a1 + a2 = 1.6, 0 < a1 < a2 < 1.6;

[0055] Step 3: Compare the obtained alloy wire difference value ZY with the alloy wire difference threshold;

[0056] If the alloy wire difference value ZY is greater than the alloy wire difference threshold, then mark this section of the alloy wire as unqualified;

[0057] If the alloy wire difference value ZY is less than the alloy wire difference threshold, then mark this section of the alloy wire as qualified;

[0058] The analysis module of the present invention sums and analyzes the differences in area (burrs or scratches) on the surfaces of n alloy wires collected, and overall judges whether the coated alloy wire is qualified and whether the burrs or scratches on the surface meet the process requirements, so as to achieve real-time monitoring of the quality of the alloy wire during the coating process. Firstly, it can mark the unqualified parts of the alloy wire, and secondly, it can cut off the unqualified alloy wire area during the later production of the alloy wire and not participate in the production preparation, thereby effectively improving the quality of the alloy wire;

[0059] The fault module, when obtaining the unqualified signal of this section of the alloy wire, first checks the scraper, and then checks the evenness of the glue on the surface of the alloy wire;

[0060] The specific working process of this fault module is as follows:

[0061] Step 1: Take the alloy wire length L as the abscissa and divide it into m detection sub-regions, obtain the corresponding different area and the scraper amplitude in each detection sub-region, and mark them as Sm m and Pd m ;

[0062] Substitute the obtained different area Sm m and the scraper amplitude Pd m into the formula to calculate the scraper influence coefficient XD; where b1 and b2 are both proportionality coefficients, b1 takes the value of 0.86, and b2 takes the value of 0.69;

[0063] The obtained scraper influence coefficient XD is compared with the scraper influence coefficient threshold;

[0064] If the scraper influence coefficient XD is greater than the scraper influence coefficient threshold, it means that the scraper amplitude affects the different areas on the surface of the alloy wire, and a scraper influence signal is generated;

[0065] If the scraper influence coefficient XD is less than the scraper influence coefficient threshold, it means that the scraper amplitude has no effect on the different areas on the alloy wire surface, and a scraper no-influence signal is generated;

[0066] Step 2: When the scraper does not affect the signal, obtain the set A{Sm1, Sm2, ..., Sm n}, by the formula , calculate the symmetric difference CDS, where i=1, 2, ..., n / 2;

[0067] Compare the obtained symmetric disparity CDS with the symmetric disparity threshold;

[0068] If the symmetrical discrepancy CDS is greater than the symmetrical discrepancy threshold, it means that the coating on the surface of the alloy wire is uneven, and an uneven coating signal of the glue is generated;

[0069] If the symmetrical difference CDS is less than the symmetrical difference threshold, it means that the surface of the alloy wire is evenly coated, and a uniform glue coating signal is generated;

[0070] Among them, under the same scraper coating conditions, the area of the alloy wire with less surface glue has a greater impact, so that the probability of burrs or scratches on the surface of the alloy wire will increase under the action of the scraper, and then the uniformity of the surface of the alloy wire can be judged;

[0071] The fault module of the present invention first determines the influence relationship between the two through the relationship between the different areas and the scraper amplitude, and then, based on this, determines whether the glue on the surface of the alloy wire is evenly coated through the difference in the opposite surfaces of the alloy wire. Therefore, through the analysis of the different areas on the surface of the alloy wire, it can also find the generated faults, facilitate the treatment of them, and improve the quality of alloy wire production.

[0072] Example 3

[0073] Based on the above embodiment 2, the laminating system further includes an alarm module;

[0074] The alarm module generates a corresponding scraper alarm signal when a scraper impact signal is obtained;

[0075] When the signal of uneven glue coating is obtained, a corresponding laminating alarm signal is generated;

[0076] The specific working process of the alarm module is as follows:

[0077] Step 1: When a scraper alarm signal is obtained, check the installation tightness of the scraper and perform corresponding tightening work to ensure stability during subsequent production of alloy wires.

[0078] Step 2: When a film coating alarm signal is obtained, check the stirring speed of the glue solution in the immersion tank to avoid problems such as large differences in the glue solution on the surface of the alloy wire due to uneven concentration of the glue solution in the immersion tank.

[0079] The alarm module of the present invention checks and repairs the problems generated by the faulty module to ensure the quality of subsequent alloy wire production.

[0080] Working principle of the present invention: The present invention sums and analyzes the differences of the (burrs or scratches) different areas on the surfaces of n alloy wires collected, and overall judges whether the film-coated alloy wires are qualified and whether the burrs or scratches on the surface meet the process requirements, so as to monitor the quality of the alloy wires in real time during the film coating process. Firstly, it can mark the unqualified parts of the alloy wires. Secondly, during the later production of alloy wires, the unqualified alloy wire areas can be cut off and not participate in the production preparation, thereby effectively improving the quality of the alloy wires.

[0081] First, judge the influence relationship between the two through the relationship between the different area and the scraper amplitude that appears, and then, based on this, judge whether the glue solution on the surface of the alloy wire is evenly coated through the difference on the opposite side of the alloy wire. Therefore, through the analysis of the different areas on the surface of the alloy wire, it can also find the generated faults, facilitate the treatment thereof, and improve the quality of alloy wire production.

[0082] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
