Description

Technical Field

[0001] This application relates to the field of steel strip detection, and more particularly to a clamp encoder assembly for steel strip. Background Technology

[0002] Steel strip inspection technology is widely used in steel strip manufacturing and defect detection, and is a key means to ensure the quality of high-end steel strips required by industries such as home appliances, automobiles, and electronics. In this technology, as the steel strip moves at a constant speed, spring pressure causes friction between the driven wheel and the steel strip, driving the wheel to roll. A coaxially connected encoder converts the angular displacement into linear displacement of the steel strip through calculation. When a defect is detected, the encoder pulse values ​​are used to calculate the coordinates of the defect on the steel strip, thereby locating the defect.

[0003] In existing technology, the driven wheel of the spring-loaded mechanism converts the linear displacement of the steel belt into angular displacement measurement by the encoder. Ideally, it relies on the fixed preload provided by the spring to achieve slip-free pure rolling transmission through friction, ensuring that the angular displacement measured by the encoder corresponds strictly to the actual displacement of the steel belt.

[0004] However, in existing technologies, the preload provided by the driven wheel in the spring-loaded contact mechanism presents the following problems: when the thickness of the steel belt decreases, the reduced preload between the driven wheel and the steel belt easily causes slippage of the driven wheel, resulting in inaccurate encoder measurements; when the thickness of the steel belt increases, the increased preload between the driven wheel and the steel belt leads to deformation of the steel belt surface. The spring-loaded contact mechanism cannot provide a stable and appropriate preload for steel belts of different thicknesses, resulting in poor adaptability of the encoder assembly to measurements of steel belts of varying thicknesses. Utility Model Content

[0005] To improve the adaptability of encoder assembly measurements, this application provides a steel strip clamp-type encoder assembly.

[0006] The steel strip clip-on encoder assembly provided in this application adopts the following technical solution: A clamp-type encoder assembly for a steel strip includes a cylinder structure, a rolling element, an encoder, and an adjustment component. The cylinder structure is mounted on a frame and rotatably connected to the rolling element. The cylinder structure can press the rolling element against the steel strip, allowing the steel strip to drive the rolling element to rotate. The encoder is mounted on the cylinder structure and connected to the rolling element. The rolling element is made of an elastic material. The adjustment component is mounted on the cylinder structure and, for steel strips of different thicknesses, can adjust the distance between the rotation axis of the rolling element and the steel strip during the final operating state of the cylinder structure.

[0007] By adopting the above technical solution, when measuring the steel belt, the cylinder structure drives the rolling element to abut against the steel belt, so that the steel belt moves and drives the rolling element to roll, thereby driving the encoder to run. During this process, the operator adjusts the distance between the center of rotation of the rolling element and the steel belt at the final state by adjusting the component, thereby adjusting the deformation caused by the rolling element squeezing the steel belt, and thus adjusting the preload applied by the rolling element to the steel belt to a stable and moderate level. Compared with the spring preload method in the prior art, this application can provide a stable and moderate preload for steel belts of different thicknesses by adjusting the component to pre-adjust the distance between the center of rotation of the rolling element and the steel belt, thereby improving the adaptability of the encoder component measurement.

[0008] Preferably, the cylinder structure includes a linear cylinder and two sets of clamping members. The linear cylinder is mounted on the frame, and the two sets of clamping members are arranged opposite each other on both sides of the steel strip. Both sets of clamping members are connected to the piston rod of the linear cylinder through a connector.

[0009] By adopting the above technical solution, two sets of clamping components are driven by a linear cylinder to abut against both sides of the steel belt, so that the steel belt is subjected to stable clamping action, thereby improving the reliability of the encoder assembly abutting against the steel belt.

[0010] Preferably, the connecting member includes a connecting block and a first hinge shaft. The connecting block is fixedly connected to the clamping member and rotatably connected to the frame through the first hinge shaft. The connecting block has a strip-shaped hole arranged radially along the rotation of the connecting block. The piston rod of the linear cylinder is provided with a second hinge shaft. The second hinge shaft is inserted into the strip-shaped hole and can slide and rotate relative to the connecting block, so as to convert the linear motion of the linear cylinder into the clamping action of the two sets of clamping members.

[0011] By adopting the above technical solution, when the piston rod of the linear cylinder moves linearly, the second hinge shaft slides and rotates relative to each other in the strip hole, so that the connecting block rotates on the frame through the first hinge shaft, driving the two sets of clamping parts to rotate synchronously, thereby completing the clamping action of the two sets of clamping parts, so that the linear motion of the linear cylinder is transformed into the clamping action of the two sets of clamping parts, improving the stability of the clamping action of the clamping parts.

[0012] Preferably, the adjusting component is an adjusting rod, which passes through the clamping member. The adjusting rod has two sets of nuts, each set of nuts abutting against both sides of the clamping member and threadedly connected to the adjusting rod, so as to fix the adjusting rod inside the clamping member. The adjusting rod has an abutting end that can abut against another set of the clamping members. The distance between the rotating shaft of the rolling element and the steel strip is adjusted by adjusting the distance of the abutting end extending out of the clamping member.

[0013] By adopting the above technical solution, when adjusting the adjusting rod, the adjusting rod slides freely within the clamping component, thereby adjusting the distance of the abutting end extending out of the clamping component. After adjustment, the two sets of nuts are abutted against the clamping component and tightened. When the abutting end abuts against another set of clamping components, the linear cylinder stops moving, and the rolling element abuts against the steel belt, thereby adjusting the distance between the rotating axis of the rolling element and the steel belt to adapt to steel belts of different thicknesses, thus improving the adaptability of the encoder assembly measurement.

[0014] Preferably, the abutting end of the adjusting rod has an arc-shaped structure.

[0015] By adopting the above technical solution and utilizing the arc-shaped structure of the adjusting rod's contact end, the contact between the adjusting rod and another set of clamping parts is made smoother, thereby improving the service life of the adjusting rod.

[0016] Preferably, there are two sets of rolling elements, which are respectively disposed on two sets of clamping members. Each set of rolling elements is rotatably connected to the corresponding clamping member. The two sets of rolling elements are disposed opposite to each other on both sides of the steel strip and can clamp the steel strip synchronously.

[0017] By adopting the above technical solution, the steel belt is clamped synchronously from both sides by two sets of rolling elements, so that the squeezing force and support force on both sides of the steel belt are relatively balanced, which improves the measurement stability of the encoder assembly.

[0018] Preferably, there are two sets of encoders, and each encoder corresponds to one of the rolling elements.

[0019] By adopting the above technical solution, two sets of encoders can be used for independent measurement, enabling the simultaneous acquisition and comparison of two measurement data, thus improving the reliability of encoder component measurement.

[0020] Preferably, the rolling element has an annular protrusion on its peripheral sidewall that contacts the steel strip, and the annular protrusion is arranged along the circumference of the rolling element.

[0021] By adopting the above technical solution, the pre-tensioning force of the steel belt on the steel belt by the annular protrusions circumferentially set on the sidewall of the rolling element is effectively avoided, thus improving the measurement accuracy of the encoder assembly.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When measuring a steel strip, a cylinder structure drives a rolling element to abut against the steel strip, causing the rolling element to roll as the steel strip moves, thus driving the encoder. During this process, the operator adjusts the distance between the rolling element's rotation axis and the steel strip at the final state by adjusting the adjustment component. This adjusts the deformation caused by the rolling element squeezing the steel strip, thereby adjusting the preload applied by the rolling element to the steel strip to a stable and appropriate level. Compared with the spring preload method in the prior art, this application uses the adjustment component to pre-adjust the distance between the rolling element's rotation axis and the steel strip, which can provide a stable and appropriate preload for steel strips of different thicknesses, improving the adaptability of the encoder assembly measurement.

[0023] 2. When the piston rod of the linear cylinder moves linearly, the second hinge shaft slides and rotates relative to each other in the strip hole, causing the connecting block to rotate on the frame through the first hinge shaft, driving the two sets of clamping parts to rotate synchronously, thereby completing the clamping action of the two sets of clamping parts. This transforms the linear motion of the linear cylinder into the clamping action of the two sets of clamping parts, improving the stability of the clamping action.

[0024] 3. When adjusting the adjusting rod, the adjusting rod slides freely within the clamping parts, thereby adjusting the distance of the abutting end extending out of the clamping parts. After adjustment, the two sets of nuts are abutted against the clamping parts and tightened. When the abutting end abuts against the other set of clamping parts, the linear cylinder stops moving, and the rolling element abuts against the steel belt, thereby adjusting the distance between the rotating axis of the rolling element and the steel belt to adapt to steel belts of different thicknesses, improving the adaptability of the encoder assembly measurement.

[0031] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0032] This application discloses a clamp-on encoder assembly with a steel strip.

[0033] Reference Figure 1 A clamp-type encoder assembly for steel strip includes a cylinder structure 2, a rolling element 3, an encoder 4, and an adjustment component 5. The cylinder structure 2 is mounted on a frame 1 and rotatably connected to the rolling element 3. The cylinder structure 2 can press the rolling element 3 against the steel strip, allowing the steel strip to drive the rolling element 3 to roll. The encoder 4 is mounted on the cylinder structure 2 and connected to the rolling element 3. The rolling element 3 is made of an elastic material. The adjustment component 5 is mounted on the cylinder structure 2. For steel strips of different thicknesses, the adjustment component 5 can adjust the distance between the rotation axis of the rolling element 3 and the steel strip in the final state of operation. The operator can adjust the distance between the rotation axis of the rolling element 3 and the steel strip in the final state by adjusting the adjustment component 5, thereby adjusting the deformation caused by the rolling element 3 pressing the steel strip, and thus adjusting the preload applied by the rolling element 3 to the steel strip to a stable and moderate level. This provides a stable and moderate preload for steel strips of different thicknesses, improving the adaptability of the encoder 4 assembly.

[0034] Reference Figure 2 The frame 1 includes a base 11, a first support 12, and a second support 13. The base 11 is set along the X-axis of the coordinate system. A first guide rail 111 is provided on the base 11. The length of the first guide rail 111 along the X-axis is the same as the length of the base 11 along the X-axis. A first slider 112 is slidably provided on the first guide rail 111. The first slider 112 is fixedly connected to the first support 12. A first locking knob 113 is provided on the first slider 112. Rotating the first locking knob 113 can unlock and lock the base 11 and the first slider 112.

[0035] The first support 12 is set along the Z-axis of the coordinate system. The first support 12 is provided with a second guide rail 121. The length of the second guide rail 121 along the Z-axis is the same as the length of the first support 12 along the Z-axis. A second slider 122 is slidably provided on the second guide rail 121. The second slider 122 is fixedly connected to the second support 13. A second locking knob 123 is provided on the second slider 122. Rotating the second locking knob 123 can unlock and lock the first support 12 and the second slider 122.

[0036] The second support 13 is set along the Y-axis of the coordinate system. The second support 13 is provided with a slide groove 131 set along the Y-axis direction. The third slider 132 is slidably mounted on the second support 13. The third slider 132 is connected to the cylinder structure 2. The third slider 132 is provided with a third locking knob 133. The third locking knob 133 and the third slider 132 are arranged opposite to each other on both sides of the second support 13. The third locking knob 133 and the third slider 132 are threadedly connected by a threaded shaft, which passes through the slide groove. Rotating the third locking knob 133 causes the third locking knob 133 to abut against the slide groove 131, thereby unlocking and locking the second support 13 and the third slider 132.

[0037] Reference Figure 3 , Figure 4 , Figure 5 The cylinder structure 2 includes a linear cylinder 21 and two sets of clamping members 22. The cylinder body of the linear cylinder 21 is fixedly connected to the third slider 132. The two sets of clamping members 22 are symmetrically arranged on both sides of the steel strip about the steel strip. The piston rod of the linear cylinder 21 is connected to the two sets of clamping members 22 respectively through two sets of connecting members 23. The two sets of connecting members 23 are symmetrically arranged about the steel strip and correspond one-to-one with the two sets of clamping members 22. The connector 23 includes a connecting block 231 and a first hinge shaft 232. The connecting block 231 is L-shaped. One end of the connecting block 231 is fixedly connected to the clamping member 22. The corner of the connecting block 231 is rotatably connected to the cylinder body of the linear cylinder 21 through the first hinge shaft 232. The other end of the connecting block 231 is provided with a strip hole 234 arranged radially along the rotation of the connecting block 231. The piston rod of the linear cylinder 21 is provided with a second hinge shaft 233. The second hinge shaft 233 is inserted into the strip holes 234 of both sets of connecting blocks 231 and can slide and rotate relative to the connecting blocks 231. When the piston rod of the linear cylinder 21 retracts and moves linearly, the second hinge shaft 233 on the piston rod slides within the two sets of strip holes 234, causing the two sets of connecting blocks 231 to rotate around the first hinge shaft 232, which in turn drives the two sets of clamping members 22 to rotate synchronously, thereby completing the clamping action of the two sets of clamping members 22. This transforms the linear motion of the linear cylinder 21 into the clamping action of the two sets of clamping members 22, improving the stability of the clamping action of the clamping members 22.

[0038] Reference Figure 1 , Figure 4 Each clamping component 22 includes a fixed rod 221 and a connecting rod 222. One side of the fixed rod 221 is fixedly connected to the connecting block 231 by bolts, and the other side of the fixed rod 221 is fixedly connected to the connecting rod 222 by bolts. When the linear cylinder 21 drives the two sets of connecting blocks 231 to rotate, it can drive the two sets of fixed rods 221 and the two sets of connecting rods 222 to rotate synchronously. An encoder 4 is provided on the other side of the connecting rod 222. The housing of the encoder 4 is fixedly connected to the connecting rod 222. A space is left in the connecting rod 222 for the insertion of a rotating shaft 41. The rotating shaft 41 can rotate in the connecting rod 222 and is coaxially fixedly connected to the rotor of the encoder 4. By using two sets of encoders 4 for independent measurement, two measurement data can be acquired synchronously and compared, which improves the reliability of the encoder 4 measurement.

[0039] Reference Figure 3 , Figure 4 Each set of rotating shafts 41 has a rolling element 3 at the other end, which is a roller 31. The roller 31 is coaxially and fixedly connected to the rotating shaft 41. The two sets of rollers 31 are respectively set on both sides of the steel belt, and can synchronously clamp the steel belt by the drive of the linear cylinder 21. The rotor of the encoder 4 is coaxially and fixedly connected to the roller 31 through the transmission shaft, so that the roller 31 drives the rotor of the encoder 4 to rotate. The stator of the encoder 4 can measure the transmission distance of the steel belt according to the number of rotations of the rotor. The circumferential sidewall of the roller 31 is provided with annular protrusions 32 that contact the steel belt. There are two sets of annular protrusions 32, which are arranged at intervals along the circumference of the roller 31. The pre-tension force of the annular protrusions 32 on the steel belt by the circumferential sidewall of the roller 31 effectively avoids the risk of slippage between the steel belt and the roller 31, and improves the measurement accuracy of the encoder 4 assembly.

[0040] The adjusting component 5 is an adjusting rod 51, which slides through the upper fixed rod 221 and faces the lower fixed rod 221. The adjusting rod 51 is offset from the steel strip in the vertical direction to ensure that it can contact the lower fixed rod 221. The adjusting rod 51 has two sets of adjusting nuts 52, located on the upper and lower sides of the fixed rod 221 respectively, and threadedly connected to the adjusting rod 51. The two sets of adjusting nuts 52 can fix the adjusting rod 51 inside the fixed rod 221, preventing it from shaking during clamping. The end of the adjusting rod 51 near the steel strip has an abutment end 53, which can abut against the lower fixed rod 221 during clamping. When adjusting the adjusting rod 51, the adjusting rod 51 slides freely within the upper fixed rod 221, thereby adjusting the distance of the abutting end 53 extending out of the upper fixed rod 221. After adjustment, the two sets of adjusting nuts 52 are abutted against the fixed rod 221 and tightened. When the abutting end 53 abuts against the other set of fixed rods 221, the linear cylinder 21 stops moving, and the roller 31 abuts against the steel belt, thereby adjusting the distance between the rotation axis of the roller 31 and the steel belt to adapt to steel belts of different thicknesses, thus improving the adaptability of the encoder 4 components.

[0041] The abutting end 53 of the adjusting rod 51 is spherical, and the side of the abutting end 53 near the steel strip has an arc structure. The other side is fixedly connected to the adjusting rod 51 by bolts. The arc structure of the abutting end 53 of the adjusting rod 51 makes the contact between the adjusting rod 51 and the other set of fixed rods 221 smoother, thus improving the service life of the adjusting rod 51.

[0042] The implementation principle of the clamp encoder 4 assembly for steel belt in this application embodiment is as follows: When the steel belt starts to transmit, the piston rod of the linear cylinder 21 retracts, driving the two sets of connecting rods 222 to move synchronously towards the steel belt, so that the rollers 31 on both sides are in contact with the upper and lower surfaces of the steel belt. As the steel belt continues to transmit, it drives the rollers 31 on both sides to rotate synchronously. The rollers 31 on both sides drive the rotors of the two encoders 4 to rotate through the corresponding rotating shafts 41. The stators of the two encoders 4 convert the rotation of the encoder rotors into corresponding electrical pulse signals, measure the transmission distance of the steel belt, and realize the real-time measurement of the length of the steel belt.

[0043] During the measurement of the steel strip, the operator adjusts the distance between the rotation axis of the roller 31 and the steel strip in the final state by adjusting the adjusting rod 51 according to the different thicknesses of the steel strip. This adjusts the deformation caused by the roller 31 squeezing the steel strip, thereby adjusting the preload applied by the roller 31 to the steel strip to a stable and moderate level, which improves the adaptability of the encoder 4 components.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
