Description

Technical Field

[0001] The invention relates to the technical field of decontamination of the surface of Wiegand wire, in particular to a surface decontamination device in the production process of Wiegand wire. Background Art

[0002] Wiegand wire is a Vicalloy wire that has been specially annealed and hardened. It is a permanent magnetic alloy wire mainly composed of metal elements such as iron, cobalt, and vanadium, and has unique magnetic properties. The working principle of Wiegand wire is based on the "Wiegand effect", which is a physical phenomenon. When the Wiegand wire is placed in an alternating external magnetic field, its magnetic poles remain at a certain point and then suddenly "flip" to the opposite polarity. This change of magnetic poles is completed within a few microseconds and generates a pulse current in a copper coil fixed near the Wiegand wire. The intensity and duration of the generated pulse are not affected by the speed of change of the external magnetic field.

[0003] Wiegand wire will inevitably be contaminated with pollutants (such as dust or oil) during the production process, so it is necessary to perform surface decontamination on it before winding it up and storing it. Currently, the surface decontamination of Wiegand wire is usually done by staff manually wiping it with a rag or by mechanical water washing.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-Figure 10 , the present invention provides a technical solution:

[0050] A surface decontamination device in the production process of Wiegand wire comprises a spiral member 1, a cylinder 4 and a driving assembly 5; wherein the spiral member 1 can be made of hard plastic material. A channel 11 is formed at the axial position of the spiral member 1, and the Wiegand wire 2 to be cleaned coaxially passes through the channel 11, and the moving direction of the Wiegand wire 2 is from left to right, such as Figure 6 and Figure 7 As shown, when the Wiegand wire 2 moves from left to right, the inner scraping end 32 can scrape the dust, oil and the like on the Wiegand wire 2, and the cleaning effect is good.

[0051] like Figure 6-Figure 8 As shown, a spiral scraping strip 3 is fixedly disposed inside the channel 11 . The spiral scraping strip 3 can be made of silicone or rubber, and the inner scraping end 32 of the spiral scraping strip 3 is elastically pressed against the outer peripheral surface of the Wiegand wire 2 .

[0052] The driving assembly 5 includes a transmission component for driving the spiral member 1 to rotate around its own axis and a reciprocating component for driving the spiral member 1 to retract along its own axial direction; wherein, the function of the transmission component driving the spiral member 1 to rotate around its own axis is that the spiral member 1 can drive the spiral scraping bar 3 to rotate, and since the inner scraping end 32 is elastically pressed against the outer peripheral surface of the Wiegand wire 2, the rotating inner scraping end 32 can use its own spiral shape to powerfully scrape the outer peripheral surface of the Wiegand wire 2, effectively removing the dirt on the outer peripheral surface of the Wiegand wire 2, and the whole process will not cause excessive bending of the Wiegand wire 2, thereby protecting the Wiegand wire 2; the function of the reciprocating component driving the spiral member 1 to retract along its own axial direction is that due to the spiral shape of the spiral member 1, its inner diameter will decrease when it is extended, thereby increasing the force of the inner scraping end 32 of the spiral scraping bar 3 on the outer peripheral surface of the Wiegand wire 2, further enhancing its scraping effect on dirt.

[0053] The cylinder 4 is wrapped around the outer circumference of the spiral element 1, and the cylinder 4 can be used in conjunction with the reciprocating component to achieve pumping water at one end and draining water at the other end to flush the Wiegand wire 2 located inside the cylinder 4; specifically, the cylinder 4 can pump water from the right end and drain water from the left end, so that water (this water body can be water mixed with a special cleaning liquid) can be introduced to clean the outer circumference of the Wiegand wire 2 during the process of scraping the outer circumference of the Wiegand wire 2 by the inner scraping end 32, and the decontamination effect is better. More importantly, since the right end of the cylinder 4 pumps water when the spiral element 1 is stretched and the left end of the cylinder 4 is discharged when the spiral element 1 returns to its original length, that is, in one expansion and contraction cycle of the spiral element 1, the water pressure of the water body inside the cylinder 4 will experience a process of decrease and increase. From a microscopic perspective, the water pressure of the water body decreases, and the distance between dirt molecules increases; the water pressure of the water body increases, and the distance between dirt molecules decreases. Such periodic reduction and increase of water pressure is more conducive to peeling off the dirt from the outer circumference of the Wiegand wire 2, and then cooperate with the inner scraping end 32 to achieve a better decontamination effect.

[0054] In the above scheme, by setting a spiral member 1 and a spiral scraping strip 3 driven to rotate by a driving assembly 5, the inner scraping end 32 of the spiral scraping strip 3 can rotate to scrape the dirt on the outer peripheral surface of the Wiegand wire 2 to achieve the purpose of removing dirt; further, the reciprocating component can drive the spiral member 1 to extend and retract, and the inner diameter of the spiral member 1 will decrease when it is extended, thereby increasing the force of the inner scraping end 32 of the spiral scraping strip 3 on the outer peripheral surface of the Wiegand wire 2, further enhancing its scraping effect on dirt; and, by using the reciprocating component, water can be pumped out from the right end of the cylinder 4 and water can be discharged from the left end, which can not only flush the dirt, but also periodically change the water pressure in the cylinder 4, which is more conducive to peeling the dirt from the outer peripheral surface of the Wiegand wire 2.

[0055] The cylinder 4 includes a storage section 41, an extension section 42 and a sliding sealing sleeve 43. The outer diameter of the storage section 41 is larger than the outer diameter of the extension section 42, and is used to limit the maximum extension length of the spiral member 1 to prevent the spiral member 1 from being damaged due to excessive extension (excessive extension of the spiral member 1 will also cause excessive squeezing force on the Wiegand wire 2 and damage the Wiegand wire 2). The Wiegand wire 2 passes through the cylinder 4 through two sliding sealing sleeves 43 for sliding sealing. The setting of the sliding sealing sleeve 43 can prevent water from overflowing from the connection position between the Wiegand wire 2 and the cylinder 4.

[0056] The storage section 41 includes a first outer cylinder 411, a sealing sleeve 412 fixedly arranged on the inner surface of the first outer cylinder 411, a first end plate 413 and a second end plate 414 sealed and fixedly arranged at both ends of the first outer cylinder 411, a one-way water inlet pipe, and a one-way drain pipe; the first outer cylinder 411, the first end plate 413 and the second end plate 414 can all be made of stainless steel, and the sealing sleeve 412 can be made of rubber. During the extension and retraction process, the spiral member 1 can achieve a sliding sealing connection through the sealing sleeve 412 and the first outer cylinder 411. The one-way water inlet pipe is connected to the extension section 42, and the one-way drainage pipe is connected to the storage section 41; the outer spiral surface of the spiral member 1 is slidingly sealed with the sealing sleeve 412, and a spiral channel 417 is formed between the spiral member 1 and the sealing sleeve 412. Water is sucked into the interior of the cylinder 4 through the one-way water inlet pipe, and then discharged from the one-way drainage pipe after passing through the spiral channel 417. The water in the spiral channel 417 flows in a spiral shape, which is conducive to flushing the dirt on the outer peripheral surface of the Wiegand wire 2 and the dirt scraped off by the shovel.

[0058] A connecting block 419 is fixed between the first end plate 413 and one end of the spiral member 1.

The spring 423 will be stretched by the piston 422 after pulling the other end of the spiral member 1 to contact the second end plate 414; the second end plate 414 is annular, one end of the second outer cylinder 421 is fixedly connected to the second end plate 414, and the inner diameter of the second end plate 414 is equal to the inner diameter of the second outer cylinder 421; the reciprocating component is used to drive the piston 422 to reciprocate left and right; the one-way water inlet pipe is fixed on the piston 422.

[0060] The first end ring 13 and the second end ring 14 are fixed at both ends of the spiral member 1 respectively; the connecting block 419 is fixed between the first end plate 413 and the first end ring 13, and the first end ring 13 is provided with a first through hole 131 for connecting the temporary storage chamber 418 and the spiral channel 417; the two ends of the spring 423 are fixedly connected to the second end ring 14 and the piston 422 respectively, and the second end ring 14 is provided with a second through hole 141 for connecting the spiral channel 417 and the buffer chamber 4110.

[0061] The inner spiral surface of the spiral member 1 is provided with a spiral groove 12, and the outer clamping end 31 of the spiral scraping strip 3 is clamped and fixed inside the spiral groove 12; a side of the inner scraping end 32 in contact with the Wiegand wire 2 is provided with a plurality of scraping grooves 321, and the opening edge of the scraping groove 321 close to the Wiegand wire 2 is a notch line 3211, which plays an important role in scraping dirt on the surface of the Wiegand wire 2, such as Figure 6 and Figure 7 As shown, the thickness of the spiral scraping strip 3 gradually decreases along the direction gradually approaching the Wiegand wire 2.

[0062] The transmission component includes a mounting frame 52, a reduction motor 51 mounted on the mounting frame 52, a first gear 53 fixedly mounted on the output shaft of the reduction motor 51, and a second gear 54 fixedly mounted on the outer side of the cylinder 4. The cylinder 4 is rotatably connected to the mounting frame 52 through a first bearing seat 521. During use, the mounting frame 52 is fixedly arranged and its position does not change.

[0063] The reciprocating component includes a reciprocating screw 56, one end of the reciprocating screw 56 is fixedly connected to the output shaft of the reduction motor 51, and the other end of the reciprocating screw 56 is rotatably connected to a U-shaped frame 55 through a second bearing seat 551, and the U-shaped frame 55 is fixedly connected to the mounting frame 52; a hollow tube 58 is coaxially fixed to one end of the piston 422, and the hollow tube 58 is coaxially sleeved on the outside of the Wiegand wire 2, and one end of the hollow tube 58 is rotatably connected to a connecting rod 57 through a second bearing seat 571, and the connecting rod 57 is fixedly connected to the screw nut 561 of the reciprocating screw 56.

[0064] The extension section 42 cooperates with the reciprocating component to increase the amount of water passing through the cylinder 4 each time the water is pumped out, thereby increasing the flushing effect on the dirt.

[0065] The sliding sealing sleeve 43 includes a sleeve 431 and a sealing ring 432 embedded in the sleeve 431 ; the two sleeves 431 are coaxially fixed to the first end plate 413 and the piston 422 respectively, and the sealing ring 432 is sealed on the outside of the Wiegand wire 2 .

[0066] The working principle of the above scheme is as follows: the mounting frame 52 is fixed to a suitable position, and the one-way water inlet pipe is connected to the water body for cleaning; then the reduction motor 51 is started. On the one hand, the reduction motor 51 drives the cylinder 4 to rotate through the first gear 53 and the second gear 54, so that the spiral member 1 and the spiral scraping strip 3 rotate together. At this time, the Wiegand wire 2 moves from left to right to scrape the dirt on the outer peripheral surface of the Wiegand wire 2; on the other hand, the reduction motor 51 drives the reciprocating screw 56 to rotate, so that the screw nut 561 thereon reciprocates, thereby 7. The second bearing seat 571 and the hollow tube 58 drive the piston 422 to reciprocate inside the second outer cylinder 421. When the piston 422 moves to the right, the spring 423 preferentially pulls the other end of the pulling spiral 1 to contact the second end plate 414, and then the spring 423 is stretched by the piston 422 that moves to the right. In this process, water is sucked into the interior of the cylinder 4 through the one-way water inlet pipe; when the piston 422 moves to the left, the water inside the cylinder 4 flows through the second through hole 141, the spiral channel 417 and the first through hole 131 and is discharged through the one-way drain pipe.
