Description

Technical Field

[0001] This application belongs to the field of copper-clad laminate production technology, specifically relating to a winding and correction device. Background Technology

[0002] In existing technologies, winding and alignment devices play a crucial role in the winding process of copper-clad laminates and other roll products. They can adjust the position of the roll in real time along the conveying and winding path, ensuring that the edges of the roll are aligned after winding. This is essential equipment for maintaining product appearance quality, improving the convenience of subsequent processing, and reducing the defect rate. However, current winding and alignment devices on the market have some shortcomings in copper-clad laminate winding scenarios.

[0003] In existing technologies, expansion shafts are often used to fix the copper-clad laminate (CCL) roll during winding. While this method provides reliable clamping, the expansion shaft's fixed position after installation makes it difficult to incorporate additional adjustable mechanisms on the winding mechanism. This results in real-time correction and adjustment of the roll during winding, often leading to uneven edges and affecting product appearance and the precision of subsequent cutting and processing. Furthermore, existing winding correction devices are weakly resistant to external interference. Factors such as roller eccentricity, bearing wear causing vibration, or accidental interference from external objects can cause the roll to shift relative to the conveyor rollers or winding shaft during transport and winding. This prevents the roll from remaining on the preset transport and winding path, further exacerbating the uneven edges after winding, leading to decreased product quality and increased production costs.

[0004] Therefore, in order to comprehensively improve the adaptability of the winding correction device in the expansion shaft winding scenario, its resistance to external interference, and the winding uniformity, it is now urgent to make improvements to enhance the winding quality and production efficiency of copper clad laminate and other coil products, and reduce the defect rate. Utility Model Content

[0005] This application addresses the technical problems in the prior art where the expansion shaft for copper clad laminate winding is fixed in position, making it difficult to design an adaptable moving adjustment structure. This results in the inability to correct deviations in real time during winding, uneven edges of the roll material affecting appearance and subsequent processing accuracy. Furthermore, the existing device is weak against external interference, and unstable rollers and external interference can easily cause the roll material to shift, exacerbating edge unevenness, leading to decreased product quality and increased production losses. Therefore, this application proposes a winding deviation correction device.

[0006] This application adopts the following solution: a winding correction device, comprising a guide roller group, a positioning roller group, and a winding roller group arranged sequentially along the winding material conveying direction. Correction sensors are provided on both sides of the guide roller group. A correction mechanism is provided between the winding roller group and a reference surface. The correction mechanism is signal-connected to the correction sensors. When the winding material is wound around the winding roller group, the correction sensors scan the edge of the winding material. The correction mechanism drives the winding material to move in a horizontal / vertical direction. The correction mechanism includes a vertical lifting mechanism provided on the reference surface and a horizontal sliding mechanism provided between the winding roller group and the vertical lifting mechanism. The vertical lifting mechanism drives the winding roller group to move in a vertical direction, and the horizontal sliding mechanism drives the winding roller group to slide in a horizontal direction.

The linkage seat is rotatably disposed on the lead screw assembly, and the power source is used to drive the lead screw assembly to rotate relative to the second base.

[0011] In some feasible embodiments, the horizontal sliding mechanism further includes limiting components disposed on both sides of the second base, the limiting components being able to abut against the take-up roller assembly to restrict the take-up roller assembly from moving away from the second base.

[0012] In some feasible embodiments, the limiting component includes limiting plates disposed on both sides of the second seat, and a buffer block disposed on the limiting plate near the take-up roller assembly.

[0013] In some feasible embodiments, the correction sensor includes grating emitters disposed on both sides of the guide roller group, grating receivers disposed on both sides of the guide roller group and located below the grating emitters, and a scanning station enclosed by the grating emitters and the grating receivers, wherein the scanning station is provided with multiple sets of scanning gratings spaced apart along its width direction.

[0014] In some feasible embodiments, positioning components are provided on both sides of the positioning roller group. When the roll material is wound on the take-up roller group, the positioning components are used to position the roll material to a preset conveying path. The positioning components include positioning seats on both sides of the positioning roller group and positioning wheels rotatably provided on the positioning seats. When the roll material is conveyed along the preset conveying path, the roll material is positioned between the two sets of positioning wheels.

[0015] In some feasible embodiments, the positioning assembly further includes an adjusting plate disposed on the positioning seat, and a group of fixing holes disposed between the positioning roller group and the adjusting plate. The adjusting plate and the positioning seat are arranged in an "L" shape, and the adjusting plate is used to adjust the distance between the two positioning rollers.

[0028] Combination Figures 1 to 10 The following content further illustrates the technical solution proposed in this application. This application adopts the following technical solution: a winding correction device, comprising a guide roller group X, a positioning roller group Y, and a winding roller group Z arranged sequentially along the winding material conveying direction. Correction sensors 1 are provided on both sides of the guide roller group X. A correction mechanism 2 is provided between the winding roller group Z and a reference surface. The correction mechanism 2 is signal-connected to the correction sensors 1. When the winding material is wound around the winding roller group Z, the correction sensors 1 scan the edge of the winding material, and the correction mechanism 2 drives the winding material to move in a horizontal / vertical direction. The correction mechanism 2 includes a vertical lifting mechanism 3 disposed on the reference surface and a horizontal sliding mechanism 4 disposed between the winding roller group Z and the vertical lifting mechanism 3. The vertical lifting mechanism 3 drives the winding roller group Z to move in a vertical direction, and the horizontal sliding mechanism 4 drives the winding roller group Z to slide in a horizontal direction.

[0029] This application provides a winding correction device, which includes a guide roller group, a positioning roller group, and a winding roller group arranged sequentially along the winding material conveying direction. Correction sensors are installed on both sides of the guide roller group, and a correction mechanism is installed between the winding roller group and a reference surface. The correction mechanism is signal-connected to the correction sensors and includes a vertical lifting mechanism and a horizontal sliding mechanism, which can simultaneously drive the winding roller group to move in both vertical and horizontal directions. This application uses correction sensors to scan the edge of the winding material in real time, and the correction mechanism adjusts the winding roller group accordingly, effectively improving the flexibility of the winding roller group and ensuring neat edges of the winding material. By setting a correction mechanism that can be adjusted in both directions, the device enhances the resistance to external interference during the winding process, avoiding winding material deviation caused by roller instability and external interference, and reducing production losses and quality degradation. It does not require modification of existing core winding components and has the advantages of strong adaptability, reasonable structure, precise adjustment, low implementation cost, and ease of promotion.

[0030] In actual implementation, the correction sensors 1 on both sides of the guide roller group X scan the edge of the roll material in real time and continuously collect the position information of the roll material (such as the offset and direction of the offset between the edge of the roll material and the preset path). When the correction sensor detects that the edge of the roll material deviates from the preset path, it transmits the offset signal (including the offset data in the horizontal / vertical direction) to the correction mechanism 2. If there is a horizontal offset of the roll material, the horizontal sliding mechanism 4 drives the take-up roller group Z to slide in the horizontal direction to correct the lateral deviation. If there is a vertical offset (such as the vertical offset caused by the height error of the roller body), the vertical lifting mechanism 3 drives the take-up roller group Z to move in the vertical direction to correct the longitudinal deviation.

[0031] In this embodiment, the vertical lifting mechanism 3 includes a first base 30 disposed on a reference surface and a plurality of lifting components 31 disposed at the corners of the first base 30. The lifting component 31 includes a lifting cylinder 32 disposed on the first base 30, a lifting plate 33 disposed on the output end of the lifting cylinder 32, and a guide component 34 disposed between the lifting plate 33 and the lifting cylinder 32. The horizontal sliding mechanism 4 is disposed on the lifting plate 33.

[0032] In this embodiment, the guide assembly 34 includes a plurality of guide posts 35 disposed at the bottom of the lifting plate 33, and a guide sleeve 36 disposed on the lifting cylinder 32 at the corresponding position of the guide posts 35, the guide sleeve 36 being fitted around the outer periphery of the guide posts 35.

[0033] In actual implementation, when the correction sensors on both sides of the guide roller group detect a vertical offset in the roll material (such as misalignment caused by roller height error or uneven roll material thickness), the correction sensors transmit the vertical offset signal to the correction mechanism control system. The system determines that the vertical lifting mechanism 3 needs to be activated. After receiving the control signal, the lifting cylinder 32 extends (or retracts) its output end in the vertical direction, driving the top lifting plate 33 to rise and fall synchronously. During the lifting process, the guide column 35 at the bottom of the lifting plate 33 and the guide sleeve 36 on the lifting cylinder 32 form a sliding fit: the guide sleeve 36 constrains the movement trajectory of the guide column 35 to prevent the lifting plate 33 from tilting or swaying due to uneven force (such as uneven weight load of the take-up roller group), ensuring that the lifting plate 33 always moves smoothly in the vertical direction.

[0034] In actual implementation, the control system is integrated into the host computer, which can be a computer, mobile phone, tablet or other device.

[0035] In actual implementation, the inner side of the guide sleeve is provided with a wear-resistant layer, and the wear-resistant layer is made of polytetrafluoroethylene.

[0036] In this embodiment, the horizontal sliding mechanism 4 includes a second base 40 disposed on the lifting plate 33, a plurality of horizontal slide rails 41 spaced apart along the width direction of the second base 40, a plurality of horizontal sliders 42 disposed at the bottom of the take-up roller group Z, and a horizontal drive assembly 43 disposed between the take-up roller group Z and the second base 40. When the horizontal sliders 42 are matched and disposed on the horizontal slide rails 41, the horizontal drive assembly 43 is used to drive the take-up roller group Z to slide along the length direction of the horizontal slide rails 41.

[0037] In this embodiment, the horizontal drive assembly 43 includes a lead screw assembly 45 disposed on the second base 40, a linkage seat 44 disposed at the bottom of the take-up roller assembly Z, and a power source disposed on the second base 40. The linkage seat 44 is rotatably disposed on the lead screw assembly 45, and the power source is used to drive the lead screw assembly 45 to rotate relative to the second base 40.

[0038] In actual implementation, when the correction sensors on both sides of the guide roller group detect a horizontal deviation of the roll material (such as left-right skew caused by external interference, or lateral misalignment caused by the parallelism error of the conveyor rollers), the deviation signal (including the deviation direction and amount) is transmitted to the control system of the horizontal sliding mechanism. The control system starts the power source (stepper motor / servo motor) on the second seat 40 according to the deviation signal. The power source outputs torque to drive the lead screw group 45 to rotate relative to the second seat 40. The linkage seat 44 at the bottom of the take-up roller group Z is threadedly rotated with the lead screw group 45, and the rotational motion of the lead screw group 45 is converted into the linear motion of the linkage seat 44. The horizontal slider 42 at the bottom of the take-up roller group Z is slidably engaged with the horizontal slide rail 41 on the second seat 40. When the linkage seat 44 drives the take-up roller group Z to move, the horizontal slider slides along the slide rail in a directional manner to avoid deviation and wobbling of the take-up roller group and ensure that it always moves smoothly in the horizontal direction.

[0039] In actual implementation, the surface of the horizontal slide rail 41 is provided with an annular lubrication groove, and solid grease is provided in the annular lubrication groove. The solid grease can realize automatic lubrication when the slider slides, reducing friction loss.

[0040] In this embodiment, the horizontal sliding mechanism 4 further includes limiting components 46 disposed on both sides of the second seat 40. The limiting components 46 can abut against the take-up roller group Z to restrict the take-up roller group Z from moving away from the second seat 40.

[0041] In this embodiment, the limiting component 46 includes limiting plates 47 disposed on both sides of the second seat 40, and a buffer block 48 disposed on the limiting plate 47 near the winding roller group Z.

[0042] In actual implementation, when the horizontal sliding mechanism 4 drives the take-up roller group Z to move along the horizontal slide rail 41 (to correct the lateral offset of the roll material), the movement range of the take-up roller group Z is limited by the limiting components 46 on both sides of the second seat 40 to ensure that the take-up roller group is always adjusted within the preset safe movement range, and to avoid the mechanism jamming caused by the horizontal slider 42 disengaging from the horizontal slide rail 41.

[0043] Furthermore, when a sudden anomaly occurs (such as a power source failure causing the take-up roller assembly to move rapidly, or an external impact causing the take-up roller assembly to deviate), the take-up roller assembly Z will quickly impact the limit plate 47. At this time, the buffer block 48 (made of rubber or polyurethane) on the side of the limit plate 47 closest to the take-up roller assembly will first contact the take-up roller assembly and absorb the impact energy through its own deformation, thus slowing down the impact speed. Subsequently, the limit plate 47 (made of rigid material, such as steel plate) provides rigid support, blocking the further movement of the take-up roller assembly and preventing it from directly impacting the second seat 40 or the end of the slide rail, thus preventing the mechanical parts from being deformed or damaged due to hard collision.

[0044] In this embodiment, the correction sensor 1 includes grating emitters 10 disposed on both sides of the guide roller group X, grating receivers 11 disposed on both sides of the guide roller group X and located below the grating emitters 10, and a scanning station 12 formed by the grating emitters 10 and the grating receivers 11. When the roll material is wound on the take-up roller group Z, the roll material is matched and disposed in the scanning station 12. The scanning station 12 is provided with multiple sets of scanning gratings at intervals along its width direction.

[0045] In actual implementation, when the roll material is conveyed along the guide roller group X, it will completely pass through the scanning station 12, and the edge of the roll material will be aligned with the preset baseline of the scanning station 12. The grating transmitter 10 continuously emits multiple sets of scanning gratings that are spaced apart along the width direction of the scanning station 12. After the grating signal passes through the area without roll material obstruction, it is accurately received by the grating receiver 11 below. At this time, the grating is in normal operation without obstruction. When the roll material is offset due to external interference, the edge of the roll material will obstruct part of the grating in the scanning station 12, causing the grating receiver at the corresponding position to be unable to receive the signal. The control system generates specific offset data by analyzing the number of obstructed gratings.

[0046] In this embodiment, positioning components 5 are provided on both sides of the positioning roller group Y. When the roll material is wound on the take-up roller group Z, the positioning components 5 are used to position the roll material to a preset conveying path. The positioning components 5 include positioning seats 50 on both sides of the positioning roller group Y, and positioning wheels 51 rotatably provided on the positioning seats 50. When the roll material is conveyed along the preset conveying path, the roll material is positioned between the two sets of positioning wheels 51.

[0047] In this embodiment, the positioning component 5 further includes an adjustment plate 52 disposed on the positioning seat 50, and a fixing hole group 53 disposed between the positioning roller group Y and the adjustment plate 52. The adjustment plate 52 and the positioning seat 50 are arranged in an "L" shape, and the adjustment plate 52 is used to adjust the distance between the two positioning wheels 51.

[0048] In actual implementation, based on the width of the roll material to be wound (such as copper-clad laminate), first adjust the spacing of the positioning components 5. By loosening the bolts of the fixing hole group 53 between the adjusting plate 52 and the positioning roller group Y, move the adjusting plate 52 along the hole position of the fixing hole group 53, driving the positioning wheels 51 on both sides to move closer or further away synchronously until the inner spacing of the two sets of positioning wheels 51 matches the width of the roll material. Then tighten the bolts to fix the adjusting plate 52 and complete the initial positioning calibration.

[0049] After the roll material is initially guided by the guide roller group X, the two sides of the roll material contact the outer peripheral surface of the positioning wheel 51. As the positioning wheel 51 rotates around the positioning seat 50 (rolling friction), the positioning wheel will rotate synchronously when the roll material is conveyed. This not only restricts the roll material within the preset conveying path through the limiting effect of the positioning wheel, but also avoids scratching the surface of the roll material by sliding friction.

[0050] If the roll material deviates slightly due to minor disturbance, the positioning wheel 51 will generate a lateral corrective force through edge contact to push the roll material back to the preset path; if the deviation exceeds the constraint range of the positioning wheel, the correction sensor of the guide roller group will accurately detect the deviation data, and then the correction mechanism of the take-up roller group will make secondary adjustments.

[0051] This application provides a winding correction device, which includes a guide roller group, a positioning roller group, and a winding roller group arranged sequentially along the winding material conveying direction. Correction sensors are installed on both sides of the guide roller group, and a correction mechanism is installed between the winding roller group and a reference surface. The correction mechanism is signal-connected to the correction sensors and includes a vertical lifting mechanism and a horizontal sliding mechanism, which can simultaneously drive the winding roller group to move in both vertical and horizontal directions. This application uses correction sensors to scan the edge of the winding material in real time, and the correction mechanism adjusts the winding roller group accordingly, effectively improving the flexibility of the winding roller group and ensuring neat edges of the winding material. By setting a correction mechanism that can be adjusted in both directions, the device enhances the resistance to external interference during the winding process, avoiding winding material deviation caused by roller instability and external interference, and reducing production losses and quality degradation. It does not require modification of existing core winding components and has the advantages of strong adaptability, reasonable structure, precise adjustment, low implementation cost, and ease of promotion.
