Description

Technical Field

[0001] The invention relates to the technical field of stainless steel detection, and in particular to a stainless steel detection and sorting device based on X-ray fluorescence. Background Art

[0002] X-ray fluorescence analysis is a technique used for material analysis, especially in the detection and quantification of elemental composition. Its principle is to irradiate the sample with X-rays so that the atoms in the sample emit characteristic X-rays, thereby identifying the elements contained in the sample and their concentrations. At present, factories often use X-ray fluorescence analysis sorting equipment when sorting stainless steel.

[0003] The existing X-ray fluorescence analysis and sorting equipment has the following technical problems in the process of sorting stainless steel parts: 1. The x-ray fluorescence of current x-ray fluorescence analysis and sorting equipment is generally set on the top of the stainless steel to be sorted, so that the x-ray fluorescence can only detect the top of the stainless steel part, and cannot detect the side or bottom of the stainless steel part, thereby reducing the sorting effect of the x-ray fluorescence analysis and sorting equipment on the stainless steel parts.

[0004] 2. At the same time, the x-ray fluorescence analysis and sorting equipment can only detect the surface of stainless steel parts, but cannot detect the inside of stainless steel. When there are other metals or impurities inside the unqualified stainless steel, the x-ray fluorescence analysis and sorting equipment cannot detect them, thereby reducing the x-ray fluorescence analysis and sorting equipment's ability to detect stainless steel.

[0022] The sleeve 9 is driven by the rotating mechanism 15 to make the second jet hole 14 rotate in sequence to correspond to each pipeline 12. At this time, the first jet hole 13 will be blocked by the inner wall of the fixed plate 11, and then the lower air pressure is introduced into the sleeve 9 through the gas transmission mechanism 16, so that the gas passes through the second jet hole 14 and the pipeline 12 and the through hole 4 to blow the lower end of one side of the stainless steel part 6, so that the stainless steel part 6 is turned against the spacer 5 or the inner wall of the body 1 until the side of the stainless steel part 6 can be detected by the x-ray fluorescence analyzer 7, so that the x-ray fluorescence analyzer 7 can be detected by the x-ray fluorescence analyzer 7. The analyzer 7 can detect all sides of the stainless steel part 6, then rotate the second jet hole 14 to correspond to the right side of the pipeline 12, and start the gas delivery mechanism 16 to introduce a larger air pressure into the interior of the sleeve 9, so that the gas passes through the second jet hole 14, the pipeline 12 and the through hole 4 to the lower end of the right side of the stainless steel part 6, so that the stainless steel part 6 will be turned against the spacer 5 with the bottom facing upward, so that the x-ray fluorescence analyzer 7 can detect the bottom surface of the stainless steel part 6, and the x-ray fluorescence analyzer 7 can fully detect the outer surface of the stainless steel part 6; When the sleeve 9 is started by the rotating mechanism 15 so that the first jet hole 13 corresponds to the pipe 12, the second jet hole 14 will be blocked by the inner wall of the fixed plate 11, and then the specific air pressure is introduced into the sleeve 9 through the air delivery mechanism 16, so that the gas enters the pipe 12 through the first jet hole 13, and then the gas in the pipe 12 blows the bottom of the stainless steel part 6 through the through hole 4, so that the stainless steel part 6 is blown up.

In this way, if there are other metals or impurities inside the stainless steel part 6 that cause the weight of the stainless steel part 6 to change, at this time, the height of the stainless steel part 6 blown up by the laser rangefinder 17 and the height of the qualified stainless steel part 6 blown up by the air pressure can be compared to determine whether the tested stainless steel part 6 is qualified, thereby achieving the purpose of detecting the inside of the stainless steel part 6; In summary, the device can detect both the inside and outside of the stainless steel part 6, and the detection effect is more comprehensive, so as to facilitate the subsequent sorting of the stainless steel parts 6 produced and tested.

[0024] By starting the brake motor 1502, the first gear 1503 drives the sleeve 9 to rotate through the second gear 1504, and then the annular block 10 rotates along the inner wall of the fixed plate 8, so that the sleeve 9 can drive the second jet hole 14 or the first jet hole 13 to correspond to the pipeline 12, so that the gas inside the sleeve 9 can enter the pipeline 12 through the first jet hole 13 or the second jet hole 14, and then the gas is ejected through the through hole 4 to blow up the stainless steel part 6 or flip the stainless steel part 6.

[0025] Embodiment three, as Figure 4 and Figure 5 As shown, on the basis of the above embodiment, the gas delivery mechanism 16 includes an air delivery pipe 1601 fixedly sleeved on the body 1, one end of the air delivery pipe 1601 extends to the interior of the sleeve 9 and is connected to the sleeve 9, and the other end of the air delivery pipe 1601 is connected to an air pressure controller 1602 fixed on the body 1, and a fan 1603 is installed on the air pressure controller 1602.

[0026] By starting the fan 1603 and the air pressure controller 1602, the fan 1603 will absorb the external gas and introduce the gas into the air pressure controller 1602, compressing it into a smaller air pressure or a larger air pressure or a specific air pressure for spraying, so that these air pressures can be introduced into the sleeve 9 through the air pipe 1601, and then enter the pipeline 12 through the first jet hole 13 or the second jet hole 14 to spray and blow up the stainless steel part 6 or flip the stainless steel part 6.

[0028] By starting the driving motor 18, the driving wheel 19 will drive the transmission belt 3 to rotate through the driven wheel 20, and then the transmission belt 3 can drive the multiple stainless steel parts 6 to move toward the X-ray fluorescence analyzer 7 in sequence through the spacer 5 until the laser rangefinder 17 can detect the stainless steel parts 6 through the through hole 4 and stop, and then the sleeve 9 is driven by the rotating mechanism 15, so that the sleeve 9 can drive the second jet hole 14 or the first jet hole 13 to correspond to the pipeline 12, and then the gas transmission mechanism 16 is started to introduce a smaller air pressure or a larger air pressure or a specific air pressure into the sleeve 9, so that the gas enters the interior of the pipe 12 through the first jet hole 13 or the second jet hole 14, and then is ejected from the through hole 4 to blow up the stainless steel part 6 or flip the stainless steel part 6 to the left partition block 5, so that the X-ray fluorescence analyzer 7 can perform a comprehensive inspection on the blown-over stainless steel part 6, and the laser rangefinder 17 can perform a height inspection on the blown-up stainless steel part 6, and then compare the inspection data with the qualified height data of the blown-up stainless steel part 6, so as to judge whether the stainless steel part 6 is of qualified weight, and then judge whether there are impurities or other metals inside the stainless steel part 6 that affect the weight.

[0029] Furthermore, there are multiple stainless steel parts 6 , and the multiple stainless steel parts 6 are respectively separated by two spacers 5 and are placed on the transmission belt 3 in sequence.

[0030] The stainless steel pieces 6 are placed separately so that when the stainless steel piece 6 is turned over onto the spacer 5 , it will not contact another stainless steel piece 6 , nor will it block another stainless steel piece 6 from being detected by the X-ray fluorescence analyzer 7 .

[0031] Embodiment 5, as Figure 2-Figure 8 As shown, on the basis of the above embodiment, a scraper 27 is fixed inside the body 1, and the bottom of the scraper 27 is movably connected to the top of the partition block 5, and side openings 21 are respectively opened at both ends inside the body 1, and a push block 22 is movably sleeved inside the side opening 21, and the push block 22 is located between the two partition blocks 5.

[0032] Through the design of the scraper 27, when the transmission belt 3 drives the stainless steel piece 6 flipped onto the partition block 5 to move, the scraper 27 can scrape the stainless steel piece 6 between the two partition blocks 5 to facilitate subsequent processing of the stainless steel piece 6. Then, by starting the electric telescopic rod 24, the push block 22 will push the stainless steel piece 6 placed between the two partition blocks 5 on the transmission belt 3, so that the stainless steel piece 6 falls into the collection box 25 through the side port 21 for collection, thereby achieving the purpose of sorting the stainless steel piece 6.

[0033] Embodiment six, as Figure 1-Figure 4 As shown, on the basis of the above embodiment, a control cabinet 26 is installed on the side of the body 1, and the control cabinet 26 is electrically connected to the X-ray fluorescence analyzer 7 and the laser rangefinder 17 and the electric telescopic rod 24 respectively.

[0034] Through the design of the control cabinet 26, the control cabinet 26 can compare and judge the data of the stainless steel parts 6 detected by the x-ray fluorescence analyzer 7 and the laser rangefinder 17 with the data of the qualified stainless steel parts 6. After the judgment, the electric telescopic rod 24 is controlled to start, so that the push block 22 pushes the unqualified stainless steel parts 6 through the side opening 21 into the collection box 25 for collection, while the qualified stainless steel parts 6 can be moved by the transmission belt 3 to the subsequent processing.
