Description

Technical Field

[0001] The present invention relates to the technical field related to amorphous strip detection, and in particular to a device and method for detecting an amorphous strip. Background Art

[0002] In daily life, people come into contact with two kinds of materials: one is crystalline material and the other is amorphous material. The so-called crystalline material refers to the material whose internal atomic arrangement follows certain rules. On the contrary, if the internal atomic arrangement is in an irregular state, it is an amorphous material. Generally, metals have orderly internal atomic arrangement and are all crystalline materials. Scientists have found that after the metal is melted, the internal atoms are in an active state. Once the metal begins to cool, the atoms will slowly arrange themselves in order according to certain crystalline rules as the temperature drops to form crystals. If the cooling process is very fast, the atoms will solidify before they have time to rearrange themselves, thus producing an amorphous alloy. Amorphous strips need to be tested after production, so they need to be matched with detection devices for testing.

[0003] In the prior art, during the production process of amorphous strip, its surface and mechanical properties need to be tested, and traditional testing is mostly sampling testing, which increases the workload of staff and has low testing accuracy. In addition, the traditional testing equipment has relatively single testing items, resulting in low testing efficiency. Summary of the invention

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] In order to improve the inspection quality, preferably, an air inlet pipe is provided at one end of the purge box, a guide channel is provided along the direction of the air inlet pipe, a volatile net is provided at the end of the guide channel, the volatile net is filled with a solution, and a purge groove is opened at the other end of the purge box, and the purge groove faces the amorphous strip.

[0008] Furthermore, a sliding block is provided on the side of the purge box, a sliding groove is provided on the inner wall of the detection box, and the sliding block is slidably connected in the sliding groove.

[0009] In order to improve the detection items, the clamping part further includes: a reciprocating rod slidably connected to the purge box, wherein a first spring is sleeved on the reciprocating rod, a baffle is fixedly connected to the reciprocating rod, and two ends of the first spring are respectively against the purge box and the baffle; a reciprocating rod is rotatably connected to the reciprocating rod, wherein a flattening roller is rotatably connected to the reciprocating rod, and two sets of flattening rollers can respectively against the two sides of the amorphous strip.

[0010] Furthermore, the reciprocating rod extends into the guide channel and is fixedly connected to a driving shaft, a cam and an impeller are provided on the driving shaft, the cam fits with the inner wall of the purge box, and the impeller corresponds to the air inlet pipe.

[0011] Furthermore, the shear frame includes two first rods rotatably connected, and a second rod slidably connected inside the first rod, wherein one end of the second rod is rotatably connected to the rotating shaft of the flattening roller, and the sensor is arranged on the second rod, and the sensor is connected to the first rod through a second spring.

[0012] Preferably, a connecting rope is wound around the rotating shafts of the first rod and the second rod, and the other end of the connecting rope is connected to the sampling head, wherein the top of the sampling head is connected to the inner top of the detection box through a third spring.

[0013] Preferably, both ends of the detection box are provided with through slots arranged at equal intervals, and the amorphous strip passes through the through slots and passes through the interior of the detection box.

[0014] Furthermore, it also includes an air pump fixedly connected to the inside of the detection box, and the output end of the air pump is connected to the air inlet pipe.

[0015] A method for detecting an amorphous strip comprises the following steps:

[0016] Step 1: Flatten and clean the surface of the amorphous strip;

[0017] Step 2: Perform surface imaging sampling on the amorphous strip in step 1;

[0018] Step 3: Perform random stage tensile testing on the amorphous strip.

[0019] Compared with the prior art, the present invention provides a device and method for detecting amorphous strips, which have the following beneficial effects:

[0020] 1. The detection device for amorphous strips, when the purge boxes slide away from each other, the two sets of clamping parts can be pressed against the upper and lower surfaces of the amorphous strips to clamp and stretch the amorphous strips; a shear frame is arranged in the detection box, the ends of the shear frame are matched with the clamping parts, and a sensor is arranged in the shear frame, so that the mechanical properties of the amorphous strips, such as tensile strength, can be directly detected during stretching; and an image sampling head is arranged in the detection box, the sampling end of which is facing the surface of the amorphous strips, and the amorphous strips that have been purged and cleaned can be accurately sampled to detect whether there are defects on the surface;

[0021] 2. The detection device for amorphous strip forms a storage space through the volatile net and the inner wall of the purge box, and the space is filled with a solution, which can be anti-rust oil or lubricant. The purpose is to spray a thin layer of anti-rust oil or lubricant when the amorphous strip is wound. This coating can effectively prevent the material from oxidative corrosion during storage and transportation, while reducing friction during cutting or forming, and protecting the surface of the strip from damage. A purge slot is opened at the other end of the purge box, that is, the purge slot at the air outlet end faces the amorphous strip. When the strip is rolled up, the upper and lower surfaces of the strip are cleaned, thereby improving the neatness of the strip rolling and the accuracy of image sampling;

[0022] 3. The amorphous strip detection device uses a flattening roller with an elastic deformation structure, and the maximum gap between the two relative flattening rollers is designed to be no more than three times the thickness of the amorphous strip, so as to ensure that the amorphous strip can be flattened when it passes through to prevent it from folding and deformation. At the same time, in the subsequent clamping process, it can still ensure the maximum contact surface with the amorphous strip to clamp and stretch, and test the mechanical properties;

[0023] 4. The amorphous strip detection device can make the upper and lower flattening rollers intermittently press against and clamp the amorphous strip through the rotation of the cam, thereby realizing the stage fixation of the amorphous strip to achieve a function similar to sampling detection, and this method will not actually sample the amorphous strip, so the integrity and consistency of the amorphous strip during detection can be guaranteed;

[0024] 5. The detection device of the amorphous strip follows the up and down movement of the flattening roller through the second rod. At this time, the two flattening rollers at both ends of the shear frame will move away from each other when in contact under the action of the slide slot, so that the two points of the amorphous strip can be fixed and stretched through the four flattening rollers. The stretching force is directly detected by the sensor to complete the mechanical property test of the amorphous strip.

[0025] 6. The detection device of the amorphous strip moves the sampling head toward the amorphous strip, so as to capture images at a closer distance. In combination with the previous cleaning of the surface of the amorphous strip by the purge tank, the quality of the amorphous strip can be further detected, thereby effectively improving the detection accuracy. When not detecting, the third spring will pull the sampling head upward away from the amorphous strip, thereby avoiding contamination of the sampling lens by the amorphous strip raw material and ensuring the accuracy of the continuous sampling process.

[0026] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. During the winding process of the amorphous strip, the mechanical properties and surface quality of the amorphous strip are tested through a shear frame, a sampling head and four purge boxes. The method is efficient and has various test items, which greatly improves the test efficiency and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0037] In the above structural design, during the winding process of the amorphous strip, the mechanical properties and surface quality of the amorphous strip are tested through the shear frame, the sampling head 8 and the four purge boxes 10. This is efficient and has a variety of test items, which greatly improves the test efficiency and accuracy.

[0038] An air inlet pipe 12 is provided at one end of the purge box 10, and an air pump 27 is fixedly connected inside the detection box 2. The output end of the air pump 27 is connected to the air inlet pipe 12, and a guide channel is formed along the air flow direction of the air inlet pipe 12. A volatile net 11 is provided at the end of the guide channel. The volatile net 11 and the inner wall of the purge box 10 form a storage space, and the space is filled with a solution. The solution can be anti-rust oil or lubricant. The purpose is to spray a thin layer of anti-rust oil or lubricant when the amorphous strip is wound. This coating can effectively prevent oxidation corrosion of the material during storage and transportation, while reducing friction during cutting or forming, and protecting the surface of the strip from damage. A purge groove 13 is provided at the other end of the purge box 10, that is, the purge groove 13 at the air outlet end faces the amorphous strip. When the strip is rolled up, the upper and lower surfaces of the strip are cleaned, thereby improving the neatness of the strip rolling and improving the accuracy of image sampling.

[0039] A sliding block 14 is provided on the side of the purge box 10 , a sliding groove 7 is provided on the inner wall of the detection box 2 , and the sliding block 14 is slidably connected in the sliding groove 7 .

[0040] In addition, the clamping part includes: a reciprocating rod 15 slidably connected to the purge box 10, wherein a first spring 17 is sleeved on the reciprocating rod 15, a baffle 18 is fixedly connected to the reciprocating rod 15, and two ends of the first spring 17 are respectively abutted against the purge box 10 and the baffle 18; and a flattening roller 16 with elastic deformation is rotatably connected to the reciprocating rod 15, and two sets of flattening rollers 16 can respectively abut against two sides of the amorphous strip.

[0041] Here, since the flattening roller 16 is an elastic deformation structure, the maximum gap between the two relative flattening rollers 16 is designed to be no more than three times the thickness of the amorphous strip, so as to ensure that the amorphous strip can be flattened when it passes through to prevent it from folding and deformation. At the same time, in the subsequent clamping process, it can still ensure the maximum contact surface clamping and stretching with the amorphous strip to test the mechanical properties.

[0042] The reciprocating rod 15 extends into the guide channel and is fixedly connected to a drive shaft 19. A cam 21 and an impeller 20 are provided on the drive shaft 19. The cam 21 fits against the inner wall of the purge box 10, and the impeller 20 corresponds to the air intake pipe 12. That is to say, in the process of continuous air intake of the air intake pipe 12, air intake can only be achieved by pushing the impeller 20 to rotate, and the rotation of the impeller 20 will drive the cam 21 to rotate, thereby realizing the regular up and down reciprocating movement of the reciprocating rod 15. With the rotation of the cam 21, the upper and lower flattening rollers 16 can intermittently resist and clamp the amorphous strip, thereby realizing the stage fixation of the amorphous strip, so as to realize a function similar to sampling detection, and this method will not actually sample the amorphous strip, so the integrity and consistency of the amorphous strip during detection can be guaranteed.

[0043] In addition, the shear frame includes two first rods 23 rotatably connected, and a second rod 22 slidably connected to the first rod 23, wherein one end of the second rod 22 is rotatably connected to the rotating shaft of the flattening roller 16, and the sensor 25 is arranged on the second rod 22, and the sensor 25 is connected to the first rod 23 through the second spring 24, and follows the up and down movement of the flattening roller 16 through the second rod 22. At this time, the two flattening rollers 16 at both ends of the shear frame will move away from each other when they come into contact under the action of the slide groove 7, so that the two points of the amorphous strip are fixed and stretched through the four flattening rollers 16, and the stretching force is directly detected by the sensor 25 to complete the mechanical property test of the amorphous strip.

[0044] At the same time, a connecting rope 26 is wound around the rotating shafts of the first rod 23 and the second rod 22, and the other end of the connecting rope 26 is connected to the sampling head 8, wherein the top of the sampling head 8 is connected to the inner top of the detection box 2 through the third spring 9. During the detection process, the sampling head 8 will move toward the direction of the amorphous strip, so as to take images at a closer distance, and in conjunction with the previous cleaning of the amorphous strip surface by the purge slot 13, the quality of the amorphous strip can be further detected, thereby effectively improving the detection accuracy. When not detecting, the third spring 9 will pull the sampling head 8 upward away from the amorphous strip, thereby avoiding the contamination of the sampling lens by the amorphous strip raw material and ensuring the accuracy of the continuous sampling process.

[0045] A method for detecting an amorphous strip comprises the following steps:

[0046] Step 1: Flatten and clean the surface of the amorphous strip to improve the quality of winding;

[0047] Step 2: Perform surface imaging sampling on the flattened and cleaned amorphous strip to improve its sampling accuracy;

[0048] Step 3: By intermittently clamping and stretching the amorphous strip, the mechanical properties of the amorphous strip are tested at random stages, making the test more reliable and universal, and ensuring the production quality of the amorphous strip.

[0049] In the present invention, during the winding process of the amorphous strip, a thin layer of anti-rust oil or lubricant is sprayed on the amorphous strip when the amorphous strip is wound. This coating can effectively prevent oxidation corrosion of the material during storage and transportation, while reducing friction during cutting or forming, and protecting the surface of the strip from damage. A purge slot 13 is provided at the other end of the purge box 10, that is, the purge slot 13 at the air outlet end faces the amorphous strip. When the strip is wound, the upper and lower surfaces of the strip are cleaned, thereby improving the neatness of the strip winding and the accuracy of image sampling, so that the upper and lower surfaces are cleaned. The two flattening rollers 16 intermittently press against and clamp the amorphous strip, thereby achieving stage fixation of the amorphous strip to achieve a function similar to sampling detection, and this method will not actually sample the amorphous strip, so the integrity and consistency of the amorphous strip during detection can be guaranteed. The two flattening rollers 16 at both ends of the shear frame will move away from each other under the action of the slide 7 when in contact, so that the two points of the amorphous strip can be fixed and stretched by the four flattening rollers 16, and the stretching force can be directly detected by the sensor 25 to complete the mechanical property detection of the amorphous strip. During the detection process, the sampling head 8 will move toward the direction of the amorphous strip, so as to take images at a closer distance, and cooperate with the previous cleaning of the amorphous strip surface by the purge slot 13, so as to further detect the quality of the amorphous strip, thereby effectively improving the accuracy of the detection, and when not detecting, the third spring 9 will pull the sampling head 8 upward away from the amorphous strip, so as to avoid the contamination of the sampling lens by the amorphous strip raw material, and ensure the accuracy of the continuous sampling process.
