Description

Technical Field

[0001] This utility model relates to the field of transmission correction technology, and in particular to a correction mechanism device for a roll-to-roll transmission system. Background Technology

[0002] Roll-to-roll conveying is a technology that uses steel belts as the transmission medium to achieve efficient data or material processing through continuous steel belt transport. Its core advantage lies in the stability and reliability of continuous steel belt transport, and it is widely used in industrial production. Primarily applied in industrial automation, it ensures stable transport of substrates and guarantees process continuity through steel belt transport.

[0003] However, in existing equipment that uses steel strips for roll-to-roll transport, the steel strips may deviate during the transport of the substrate. This deviation can cause lateral displacement between the upper and lower steel strips, affecting product quality and potentially damaging the steel strips. Therefore, a steel strip correction system is crucial for steel strip transport.

[0004] Therefore, there is an urgent need to provide a correction mechanism for a roll-to-roll transport system, which can correct the deviation of the steel strip compared to existing technologies. Utility Model Content

[0005] This invention addresses the technical problems existing in the prior art by providing a web-correction mechanism for a roll-to-roll transmission system.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A web-correcting mechanism for a roll-to-roll transport system includes a web-correcting component and a detection component. Both the web-correcting component and the detection component are mounted on a frame. The frame is divided into an upper layer and a lower layer. An upper roller is rotatably connected to both ends of the upper frame, and a lower roller is rotatably connected to both ends of the lower frame. The upper and lower rollers are also slidably arranged along the length of the frame. A steel strip is wound around the upper and lower rollers. A web-correcting component and a detection component are correspondingly mounted at each end of the upper roller, and the same applies to each end of the lower roller. The detection component detects whether the steel strip on its corresponding side has shifted, and the web-correcting component corrects the position of the shifted steel strip detected by the detection component.

The guide rail is fixed on the frame, the bracket is slidably connected to the guide rail, the roller is rotatably mounted inside one end of the bracket, the first displacement sensor is mounted on the side of the bracket away from the roller, and the roller is positioned towards the steel strip.

[0025] The technical solution of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are not all embodiments of this utility model.

It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] like Figure 1 As shown, this utility model provides a correction mechanism device for a roll-to-roll transport system, including a correction component 3, a detection component 4, and a position sensor 5. The frame 9 is divided into an upper layer and a lower layer. The two ends of the upper frame 9 are rotatably connected to upper rollers 1, and the two ends of the lower frame 9 are rotatably connected to lower rollers 2. A steel strip 6 is wound between the two upper rollers 1 and between the two lower rollers 2. The detection component 4 is installed in the upper frame 9 and the detection component 4 is also installed in the lower frame 9. The detection component 4 is used to detect whether the steel strip 6 has shifted position. A correction component 3 is provided at both ends of the upper roller 1 along its axial direction and at both ends of the lower roller 2 along its axial direction. The correction component 3 is used to correct the position of the steel strip 6 that has shifted as detected by the detection component 4. Each correction component 3 is provided with a corresponding detection component 4.

[0027] like Figure 2As shown, the correction assembly 3 includes a hydraulic cylinder 31, a linear guide rail 32, a bearing housing 33, and a roller self-aligning bearing 34. The hydraulic cylinder 31 is fixed on the frame 9. Bearing housings 33 are fitted at both ends of the upper roller 1 and the lower roller 2. Each bearing housing 33 is connected to a roller self-aligning bearing 34. The inner ring of each roller self-aligning bearing 34 is fixedly connected to both ends of the upper roller 1 or the lower roller 2, and the outer ring is fixedly connected to the inner ring of the bearing housing 33. A hydraulic cylinder 31 is provided on the side wall of each bearing housing 33. The output end of each hydraulic cylinder 31 is fixedly connected to its corresponding bearing housing 33. The bearing housing 33 is slidably connected to the frame 9 through the linear guide rail 32. A linear guide rail 32 is provided above and below each bearing housing 33. The linear guide rail 32 is fixed on the frame 9, and the length direction of the linear guide rail 32 is perpendicular to the axis of the upper roller 1 or the lower roller 2. When the hydraulic cylinder 31 extends, the bearing seat 33 moves along the length of the linear slide rail 32. During the movement of the bearing seat 33 along the length of the linear slide rail 32, the roller self-aligning bearing 34 inside it will drive the upper roller 1 or the lower roller 2 to deflect, resulting in axial movement along the upper roller 1 and the lower roller 2, thereby correcting the position of the upper roller 1 and the lower roller 2.

[0028] like Figure 3 As shown, a connector 8 is provided on the frame 9. Connectors 8 are provided at both ends of the upper roller 1 and both ends of the lower roller 2. A position sensor 5 is fixedly installed at one end of each connector 8 near the steel strip 6. When each position sensor 5 detects the edge position of the steel strip 6, it indicates that the offset position of the steel strip 6 has reached the limit value, and the whole machine stops running.

[0029] The frame 9 is also equipped with a second displacement sensor 7. Each bearing housing 33 is connected to a second displacement sensor 7. The second displacement sensor is used to detect the movement displacement of the bearing housing 33 along the linear slide rail 32.

[0030] like Figure 4As shown, the detection component 4 includes a first displacement sensor 41, a spring 42, a guide rail 43, a bracket 44, and a roller 45. The guide rail 43 is fixed on the frame 9, and the bracket 44 is slidably connected to the guide rail 43. The roller 45 is rotatably mounted on one end of the bracket 44, and the spring 42 is fixedly connected to the other end of the bracket 44. The other end of the spring 42 is fixedly connected to the upper end of the frame 9. The first displacement sensor 41 is also provided on the side of the bracket 44 where the spring 42 is located. The first displacement sensor 41 is fixed on the frame 9. The detection end of the first displacement sensor 41 is correspondingly set on the side wall of the bracket 44 away from the roller 45. The roller 45 is correspondingly set on the side of the steel belt 6. When the steel belt 6 deviates, the side of the steel belt 6 applies a force to the roller 45. The roller 45 drives the bracket 44 to move along the length of the guide rail and in the compression direction of the spring 42. When the first displacement sensor 41 contacts the bracket 44 and generates a value, it indicates that the steel belt 6 has deviated. The reading of the first displacement sensor 41 is the displacement of the steel belt 6 on that side.

[0031] The first displacement sensor 41, the second displacement sensor 7, and the position sensor 5 are all electrically connected to the controller, specifically using a PLC control chip. The first displacement sensor 41, the second displacement sensor 7, and the position sensor 5 are each connected to one port of the PLC chip. The specific connection circuits between the first displacement sensor 41, the second displacement sensor 7, and the position sensor 5 and the PLC chip adopt existing connection circuits, which will not be described in detail here.

[0032] The working principle of the correction mechanism device of the roll-to-roll conveying system provided by this utility model is as follows: After the detection component 4 detects that the corresponding side of the corresponding steel strip 6 has shifted, the corresponding correction component 3 is activated. When the oil cylinder 31 extends, it drives the bearing seat 33 to move along the length direction of the linear slide rail 32. During the movement of the bearing seat 33 along the length direction of the linear slide rail 32, the roller self-aligning bearing 34 inside it will drive the upper roller 1 or the lower roller 2 to deflect, resulting in axial movement along the upper roller 1 and the lower roller 2, thereby correcting the position of the upper roller 1 and the lower roller 2. When the position sensor 5 detects the position of the corresponding end of the steel strip 6, the machine is stopped.

[0033] This invention sets up a detection component 4, a correction component 3, and a position sensor 5 at the end of each roller. When the steel strip 6 deviates, the first displacement sensor 41 detects the deviation value and then drives the hydraulic cylinder 31 to extend, driving the upper roller 1 and the lower roller 2 to perform correction. It can accurately detect and correct the deviation of the steel strip 6 in different directions, thereby realizing the correction of the steel strip 6.

[0034] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
