Description

Technical Field

[0001] The invention belongs to the field of strip thickness detection, in particular to a thickness detection device and a detection method applied to amorphous alloy strips. Background Art

[0002] Amorphous alloy materials, also known as metallic glass or liquid metal, are a disruptive new generation of green, environmentally friendly, high-performance metal materials that integrate excellent properties such as high strength, high hardness, corrosion resistance, superplasticity, and soft magnetism. They have important strategic application value in high-tech fields such as new energy, high-end manufacturing, national defense and nuclear fields, and key aerospace components.

[0003] The rapid development of science and technology has increased the requirements for motor speed and power density. To increase the speed and power density, this can be achieved by increasing the strength of the stator and rotor core materials, and amorphous alloy materials can meet the needs. Therefore, it is necessary to make amorphous alloy materials into alloy strips, and then process and cut them into stator and rotor cores. When processing the strips into stator and rotor cores, the thickness of the strips needs to be tested to ensure the uniformity of the thickness of the strips.

[0004] The thickness of the strip can be detected by a laser thickness detector. During the detection, the rolled strip is flattened and conveyed to the bottom of the laser detector for detection. After that, the detected strip is synchronously wound with a roller set at the other end. In this process, it is necessary to keep the strip horizontal and the tension constant to reduce the damage and breakage of the strip due to tension changes. Since the tension is affected by many factors, such as the transportation speed and height adjustment, etc., the tension is unstable and the strip will still break during the detection process. Once the strip breaks, the strip may fly out and collide with the detector, causing damage to the detector and making it impossible to control the fracture of the strip. Summary of the invention

DETAILED DESCRIPTION

[0036] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0037] like Figure 1 to Figure 2 As shown, a thickness detection device for amorphous alloy strip according to an embodiment of the present invention comprises a base 1, two strip coils 11 are arranged on both sides of the top of the base 1, the middle connection position of the two strip coils 11 is a first strip 12, a laser detector 13 is fixedly installed on the side wall of the base 1, a detection base plate 14 is fixedly installed at the top center of the base 1, an adjustment device 2 is arranged on the detection base plate 14, and a control device 3 is arranged on one side of the adjustment device 2;

[0038] like Figure 3 to Figure 4 As shown, the adjustment device 2 includes a first conveying roller 26 and a limiting conveying roller 27, a telescopic screw 24 is provided at the end of the first conveying roller 26, and a control device 3 is provided at a symmetrical position of the limiting conveying roller 27 with respect to the central axis of the detection bottom plate 14;

[0039] like Figure 5 As shown, the control device 3 includes a second conveying roller 35 and a conveying control roller 37. The inner wall of the end of the conveying control roller 37 is slidably provided with a centrifugal component 36. The end of the second conveying roller 35 is provided with a following component 33. The centrifugal component 36 is connected to the second conveying roller 35 through the following component 33. The second conveying roller 35 and the conveying control roller 37 rotate to transport and bend the first strip 12. The centrifugal component 36 slides toward the inner wall edge of the conveying control roller 37 through centrifugal force to control the rotation of the second conveying roller 35 and the conveying control roller 37.

[0040] It should be noted that, considering that the amorphous alloy strip is generally inspected by laser irradiation, a certain tension needs to be maintained during the inspection so that the first strip 12 is in a horizontal state. Therefore, when the coil just passes through the second conveyor roller 35 during the inspection, some bending phenomena will occur. When the non-metallic strip passes through the second conveyor roller 35, it may break due to uneven thickness during manufacturing and inaccurate tension control of the coil. The first strip 12 will be pulled out quickly after breaking, resulting in the problem that the first strip 12 will hit the laser detector 13 after breaking. In order to solve this problem, the following improvements are made:

[0041] like Figure 2 As shown, firstly, the non-metallic strip is placed on the roller arranged at the upper right end of the base 1, and then the strip roll 11 is pulled out to become the first strip 12, passes through the center of the second conveying roller 35 and the conveying control roller 37, and then passes through the upper ends of the two first conveying rollers 26, and passes through the bottom end of the limiting conveying roller 27 arranged at the upper edge of the detection bottom plate 14, until it enters the Figure 2On the strip roll 11 at the left end shown, the telescopic screw 24 is then started to rise, so that the first strip 12 directly below the laser detector 13 is in a horizontal state, and then any strip roll 11 can be driven by the motor, so that the first strip 12 continues to move from directly below the laser detector 13, so as to detect the thickness of the first strip 12. The first strip 12 is prone to breakage when it is just bent. When the first strip 12 breaks due to bending and tension changes, the first strip 12 drives the conveying control roller 37 to rotate faster, thereby driving the centrifugal component 36 to slide inside the conveying control roller 37, and the centrifugal component 36 is fixedly connected to the following component 33. Therefore, under the action of the following component 33 and the centrifugal component 36, the conveying control roller 37 is locked to prevent the conveying control roller 37 from loosening the edge of the ribbon and hitting the laser detector 13, thereby protecting the laser detector 13 and protecting the strip roll 11 after detection to prevent the strip roll 11 from automatically loosening due to lack of force.

[0042] like Figure 3 As shown, the adjusting device 2 includes a limiting conveying roller 27 fixedly installed on the top edge of the detection base plate 14, and the limiting conveying roller 27 is fixedly installed with a first fixed block 22 on the top axially symmetrically about the detection base plate 14, and the first fixed block 22 and the limiting conveying roller 27 are internally rotatably installed with a first screw 21, and the outer wall of the first screw 21 is threadedly installed with two first sliders 23, and the two first sliders 23 are symmetrical about the center of the detection base plate 14, and the top of the first slider 23 is fixedly installed with a telescopic screw 24, and the top of the telescopic screw 24 is fixedly installed with a second fixed block 25, and the inside of the second fixed block 25 is rotatably installed with a first conveying roller 26, and the first conveying roller 26 rotates to transport the first strip 12.

[0043] It should be noted that the first screw 21 is driven to rotate by the motor, and the rotation of the first screw 21 drives the two first sliders 23 to move synchronously toward or away from the center of the laser detector 13, and the first slider 23 and the telescopic screw 24 are provided with transmission parts inside. When the first slider 23 approaches the center of the laser detector 13, the telescopic screw 24 rises synchronously, and vice versa, the telescopic screw 24 falls synchronously, thereby adjusting the tightness of the first strip 12, so that the first strip 12 transported at the lower end of the laser detector 13 maintains a horizontal position for easy detection.

[0044] like Figure 3 to Figure 4As shown, the control device 3 includes a first control block 31 fixedly mounted on the side wall of the first fixed block 22, an adjusting component 32 is arranged inside the first control block 31, the side of the adjusting component 32 is connected to the following component 33, a third fixed block 34 and a centrifugal component 36 are fixedly mounted at both ends of the following component 33, a second conveying roller 35 is rotatably mounted inside the third fixed block 34, a conveying control roller 37 is rotatably mounted on the end of the centrifugal component 36, the following component 33 and the centrifugal component 36 are used to control the rotation of the conveying control roller 37, and the adjusting component 32 is used to adjust the angle of the conveying control roller 37 located on the outer wall of the second conveying roller 35.

[0045] It should be noted that, since the lifting and lowering of the telescopic screw 24 will cause the angle of the first strip 12 transported between the first conveying roller 26 and the second conveying roller 35 to change, an adjustment component 32 is provided inside the first control block 31. The adjustment component 32 can adjust the angle of the second conveying roller 35 and the centrifugal component 36 connected to the following component 33, so that the following component 33 rotates and adjusts the angle of the conveying control roller 37 with the center of the centrifugal component 36, so that the conveying control roller 37 is always parallel to the conveying direction of the first strip 12. The following component 33 can allow the second conveying roller 35 and the conveying control roller 37 to clamp the first strip 12 after the first strip 12 breaks, and transport it a short distance along the conveying direction of the first strip 12, thereby reducing the tension change on the strip roll 11 and the first strip 12 after detection, and protects the laser detector 13 while protecting the strip roll 11 and the first strip 12 to prevent the wound strip roll 11 from spreading after the tension change.

[0046] like Figures 5 and 6 As shown, the adjustment component 32 includes a fourth fixed block 321 fixedly mounted on the side wall of the first control block 31, a first adjustment rod 322 is slidably mounted inside the fourth fixed block 321, a first rotating block 323 is fixedly mounted on the top of the first adjusting rod 322, a first rotating plate 325 is rotatably mounted inside the first control block 31, a rotation limiting column 326 is fixedly mounted on the side wall of the first rotating plate 325, a fifth fixed block 324 is rotatably mounted on the outer wall of the rotation limiting column 326, an end of the fifth fixed block 324 is rotatably mounted on the first rotating block 323, and the first adjustment rod 322 is raised and lowered to drive the first rotating plate 325 to rotate and adjust the angle of the conveying control roller 37 located outside the second conveying roller 35.

[0047] It should be noted that when it is necessary to adjust the angle of the following component 33, the first adjusting rod 322 can be raised and lowered to drive the first rotating block 323 and the fifth fixed block 324 to descend, and the descent of the fifth fixed block 324 drives the rotating limit column 326 to descend synchronously, and the synchronous descent of the rotating limit column 326 drives the first rotating plate 325 to rotate, and the rotation of the first rotating plate 325 can drive the following component 33 to rotate about the center of the third fixed block 34, thereby adjusting the position of the conveying control roller 37.

[0048] like Fig. 9 As shown, the following component 33 includes a first following block 331 fixedly installed at the end of the first rotating plate 325, a following groove 332 is fixedly installed at the end of the first following block 331, a following column 334 is slidably installed inside the following groove 332, and first springs 333 are fixedly installed on both side walls of the following column 334 respectively, and the end of the first spring 333 is fixedly installed on the inner wall of the following groove 332, and a following limit block 335 is fixedly installed on the end of the following column 334, and a third fixed block 34 is fixedly installed on the side wall of the end of the following limit block 335 close to one end of the first following block 331, and a second conveying roller 35 is rotatably installed inside the third fixed block 34, and a centrifugal component 36 is fixedly connected to the end of the following limit block 335 away from one end of the first following block 331.

[0049] It should be noted that rotating the first rotating plate 325 drives the first follower block 331 to rotate, and the rotation center of the first follower block 331 is the same as the center of the third fixed block 34. Therefore, the rotation of the first follower block 331 drives the follower column 334 to rotate, and the follower column 334 is maintained at the center position inside the follower groove 332 under the action of the first spring 333. The side wall of the follower column 334 is fixedly connected to the side wall of the follower limit block 335. One end of the follower limit block 335 is fixedly installed on the third fixed block 34, and the other end is fixedly installed on the centrifugal assembly 36. Therefore, when the first follower block 331 rotates, it can drive the conveying control roller 37 to rotate along the center of the third fixed block 34, so that the conveying control roller 37 is horizontal with the conveying direction of the first strip 12.

[0050] like Figure 5 and Figure 7 as well as Figure 8 and Fig. 9As shown, a conveying groove 371 is provided at the end side wall of the conveying control roller 37, and the centrifugal assembly 36 includes a centrifugal block 364 slidably mounted inside the conveying groove 371, and a centrifugal protrusion 3641 is fixedly mounted on one side wall of the centrifugal block 364, and a second spring 363 is slidably mounted on the other side wall of the centrifugal block 364 through a mortise and tenon structure, and a spring slide 362 is fixedly mounted on the side wall of the second spring 363, and a second spring 363 is also provided on the end of the spring slide 362, and a first telescopic rod 361 is fixedly mounted on the bottom end of the inner wall of the conveying groove 371, and the first The output end of the telescopic rod 361 is slidably connected to the second spring 363 at the bottom end of the spring slide plate 362 through a mortise and tenon structure, a first tooth 365 is fixedly installed on the bottom end of the inner wall of the centrifugal block 364, a locking column 367 is rotatably installed at the center of the inner wall of the conveying groove 371, and a plurality of second teeth 368 are fixedly installed on the outer wall of the locking column 367, and a centrifugal limiting hole 366 is provided on the side wall of the centrifugal block 364, and a limiting control part 369 is slidingly provided inside the centrifugal limiting hole 366, and the limiting control part 369 is used to limit the position of the centrifugal block 364.

[0051] It should be noted that when the transmission control roller 37 accelerates its rotation, it will drive the centrifugal block 364 to move along the direction of the centrifugal protrusion 3641, thereby driving the first tooth 365 to engage with the second tooth 368, while the second tooth 368 is in a fixed state and does not rotate, and the centrifugal block 364 rotates with the transmission control roller 37, so that when the first tooth 365 contacts the second tooth 368, the rotation state of the transmission control roller 37 is converted into a static state, thereby preventing the first strip 12 from hitting the laser detector 13 after the strip breaks, causing damage to the laser detector 13. After the transmission control roller 37 stops, it will no longer be subjected to centrifugal force. Therefore, a limit control member 369 is provided at the end of the locking column 367. When the centrifugal limit hole 366 is combined with the output end of the limit control member 369, the centrifugal block 364 can be limited to prevent the centrifugal block 364 from rebounding when it does not rotate, and continue to clamp the fracture position of the first strip 12 after the strip breaks.

[0052] like Figure 8As shown, the limit control component 369 includes a second circular plate 3692 fixedly installed on the end of the locking column 367, a second slide plate 3694 is slidably installed on the outer wall of the locking column 367, a third spring 3693 is fixedly installed on one side wall of the second slide plate 3694, the end of the third spring 3693 is fixedly installed on the side wall of the second circular plate 3692, a centrifugal limit column 3696 is fixedly installed on the other side wall of the second slide plate 3694, the second slide plate 3694 slides on the outer wall of the locking column 367 to drive the centrifugal limit column 3696 to slide inside the centrifugal limit hole 366, a first cylinder 3691 is fixedly installed on the side wall of the second circular plate 3692, and the end of the first cylinder 3691 is fixedly installed on the end of the follower limit block 335.

[0053] It should be noted that the centrifugal limit column 3696 is always in contact with the side wall of the centrifugal block 364 under the action of the third spring 3693. When the centrifugal block 364 moves under the action of centrifugal force and drives the first tooth 365 to engage with the second tooth 368, the centrifugal limit hole 366 engages with the centrifugal limit column 3696, thereby preventing the centrifugal block 364 from rebounding under the action of the second spring 363, thereby continuously clamping the first strip 12 after the first strip 12 breaks.

[0054] like Figure 8 As shown, an adjustment handle 3695 is fixedly installed on the outer wall of the second slide plate 3694 , and the transmission control roller 37 is kept concentric with the locking column 367 and the first cylinder 3691 .

[0055] It should be noted that an adjustment handle 3695 is fixedly installed on the outer wall of the second slide 3694 to facilitate resetting the second slide 3694. The transmission control roller 37 is concentric with the locking column 367 and the first cylinder 3691, so that when the centrifugal block 364 moves rapidly under the centrifugal force, the centrifugal limit column 3696 engages with the centrifugal limit hole 366.

[0056] like Figure 1 and Figure 3 As shown, the first control block 31 , the adjustment component 32 , the following component 33 and the centrifugal component 36 are symmetrically arranged at the end of the second conveying roller 35 .

[0057] It should be noted that the first control block 31, the adjustment component 32, the following component 33 and the centrifugal component 36 are symmetrically arranged at the ends of the second conveying roller 35, so that the second conveying roller 35 is subjected to balanced force when it stops rotating.

[0058] A thickness detection method for an amorphous alloy strip, the method using the thickness detection device for an amorphous alloy strip as described above, comprises the following steps:

[0059] Step 1: Wind the strip roll 11 on the upper end of the base 1, then pull the strip roll 11 out to the shape of the first strip 12, pass the first strip 12 through the outer wall of the second conveying roller 35, then pass through the two first conveying rollers 26 on the upper end of the detection bottom plate 14, and wind it onto the strip roll 11 at the other end, adjust the direction of the follower component 33 so that the conveying control roller 37 is parallel to the conveying direction of the first strip 12, and complete the preparation work before detection;

[0060] Step 2: Then, the telescopic screw 24 is started to adjust the tightness of the first strip 12, so that the first strip 12 is kept horizontal during transportation, and the strip roll 11 is driven to rotate by the motor, and the first strip 12 passes the lower end of the laser detector 13, and the laser detector 13 is started, and the first strip 12 is continuously transported to perform thickness detection;

[0061] Step 3: The first strip 12 is uneven during winding after detection, and the tension changes greatly, so it will break at the position of the second conveying roller 35. When the first strip 12 is detected to be broken, the conveying control roller 37 drives the centrifugal assembly 36 to rotate rapidly, so that the centrifugal assembly 36 slides on the inner wall of the end of the conveying control roller 37, and then the conveying control roller 37 is locked by the following assembly 33 and the centrifugal assembly 36 to prevent the first strip 12 from being quickly pulled away and hitting the laser detector 13 after breaking, causing damage to the laser detector 13.

[0062] Step 4: After the detection is completed, the telescopic screw 24, the transmission control roller 37 and the second transmission roller 35 are reset, and the next round of detection can be carried out.

[0063] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
