Background

The roll-to-roll (roll-to-roll) process is a high-efficiency, continuous production process that is specialized for flexible films. The roll-to-roll process is a process in which a film material is rolled out from a cylindrical material, and then a function of a specific application is added to the film material, or a process is performed on the surface of the film material, and then the film material is rolled into a cylindrical shape. In the manufacturing process, the roll-to-roll (roll-to-roll) process can reduce the production cost because the vacuum dust-free environment is not used and huge waste liquid treatment is not performed, and is widely applied to the manufacturing process of devices such as LCD (Liquid Crystal Display ), electronic paper, thin film solar cells or RFID (Radio Frequency Identification ).

In the related art, a process apparatus based on a roll-to-roll process generally includes an unreeling roller, a process device, and a wind-up roller. The process equipment based on the roll-to-roll process can realize the processes of precise stamping, film pasting, film coating and the like. For example, the unreeling roller conveys the film materials to the process device, and the film materials are conveyed to the reeling roller for reeling after the film materials sequentially pass through the process device for processing.

However, in the related art, the thickness of both side edges of the film material formed by the stretching process is easily smaller than the thickness of the middle region of the film material. Therefore, the uneven thickness of the film material is easy to cause small tension at the two side edges of the film material, so that uneven folds are easy to be generated, and the processing quality and the rolling quality of the film material are easy to be influenced. Therefore, the process equipment based on the roll-to-roll process in the related technology has poor process performance and low yield.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In the related art, the film material formed by the stretching process easily causes the thickness of the two side edges of the film material to be smaller than the thickness of the middle region of the film material. Therefore, uneven wrinkles are easily generated because the tension of the edges on both sides of the film is small due to uneven thickness of the film. When the film material is processed by the process equipment, the yield of the edge area of the film material is low, so that the overall yield of the film material is affected. In addition, uneven folds on the edges of two sides of the film material can also influence the rolling quality of the film material. Therefore, the process equipment based on the roll-to-roll process in the related technology has poor process performance and low yield.

The technical scheme disclosed by each embodiment of the application is described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 5, an embodiment of the present application discloses a process apparatus based on a roll-to-roll process, and the disclosed process apparatus includes a frame 100, an unreeling roller 200, a reeling roller 300, a detecting device 400, a controller 500, a driving mechanism 800, and a supporting roller 600.

The rack 100 provides a mounting base for other components of the process equipment. The unreeling roller 200, the reeling roller 300, the detecting device 400 and the supporting roller 600 may be connected to the frame 100. The unreeling roller 200 is used for providing the film 900 for the process equipment, and the roll-to-roll process is used for processing the film 900 with flexible property according to the process procedure of the roll-to-roll process, and the film 900 is wound on the unreeling roller 200. The film 900 on the unwind roll 200 needs to enter a processing device for processing. For example, the process device may be a precision imprinting device, thereby enabling a precision imprinting process. Or the process equipment can be a film pasting device, a film plating device and the like, so that the film pasting and film plating process can be realized, and of course, the process equipment can also realize other processing processes, and the process equipment is not limited in the specification. The wind-up roll 300 is used for winding up the processed film 900. Specifically, after the processing of the process device is completed, the film 900 is conveyed to the wind-up roller 300, and is rewound on the wind-up roller 300. Since the unreeling roller 200 needs to rotate when the film 900 is unreeled and transported and the reeling roller 300 winds the film 900, the unreeling roller 200 and the reeling roller 300 are both rotatably connected with the frame 100.

The support roller 600 is located between the unwind roller 200 and the wind-up roller 300, and the support roller 600 is used for supporting the film 900 transferred from the unwind roller 200 to the wind-up roller 300. The detection device 400 is used for detecting data representing tension of the film 900. The area detected by the detection device 400 is the edge area of both sides of the film 900. That is, the detection range of the detection device 400 corresponds to both side edge regions of the film 900. The two side edge regions of the film 900 referred to herein are edge regions in the width direction of the film 900. It can be understood that the conveying direction of the film 900 is the length direction of the film 900. The edge region of the membrane 900 may be defined by taking the edge of the membrane 900 as an initial boundary, and then a distance is defined in a direction towards the middle region of the membrane 900, and a region between the distances is the edge region.

The data used to characterize tension described above refers to data that is able to discern tension changes. The tension of the membrane 900 is mainly expressed in the degree of flatness of the surface of the membrane 900. Specifically, when the local tension of the film 900 is small during the conveyance of the film 900, uneven wrinkles may be generated in the local portion of the film 900. Therefore, the data detected by the detecting device 400 of the present application can be understood as the data of the level of the surface of the film 900.

The driving mechanism 800 is connected to the support roller 600. The detection device 400 is electrically connected to the controller 500. The controller 500 is in control connection with the driving mechanism 800. The controller 500 controls the driving mechanism 800 to operate according to the data transmitted from the sensing device 400.

In a specific working process, when the data acquired by the detection device 400 exceeds the preset data range, the controller 500 may control the driving mechanism 800 to drive the supporting roller 600 to move, so as to adjust the relative position of the supporting roller 600, and correct the tension of the edge regions on both sides of the film 900 transmitted between the unreeling roller 200 and the reeling roller 300. The relative position of the support roller 600 may be understood as the relative position between the support roller 600 and at least one of the wind-up roller 300 and the unwind roller 200, or the relative distance between the support roller 600 and at least one of the wind-up roller 300 and the unwind roller 200.

The specific working principle of the application is that the driving mechanism 800 drives the position of the supporting roller 600 to change, so that the friction force between the film 900 and the supporting roller 600 is increased, and the edges of the two sides of the film 900 are stretched, thereby playing a role in adjusting tension.

In the embodiment disclosed by the application, the tension of the two side edge regions of the film 900 is detected in real time in the process of transmission between the unreeling roller 200 and the reeling roller 300, and the detected tension exceeds a preset value, and is regulated in real time through the driving mechanism 800, so that the tension of the two side edge regions of the film 900 is ensured to be kept within a preset range, uneven folds are not easy to appear in the two side edge regions of the film 900, and the film 900 has better processing quality and reeling quality. Therefore, the process performance of the process equipment is better, and the yield is higher.

In a specific application scenario, the film 900 formed by using a stretching process is wound on the unwinding roller 200, and the detecting device 400 in the present application may be disposed between the process device and the unwinding roller 200. When the detecting device 400 detects that the edge of the film 900 is creased, the support roller 600 moves to correct the tension of the edge region of the film 900. Therefore, the edge area of the film 900 of the process device is relatively flat, so that the processing yield of the film 900 is improved.

Or, in another application scenario, after the film 900 is processed by the process device, the film 900 is easily affected by factors such as temperature and stretching, and the tension of the edge area of the film 900 is easily changed. In order to avoid wrinkling of the edges of the membrane 900 during the rolling process of the membrane 900. The detecting device 400 may be disposed between the wind-up roll 300 and the support roll 600. When the detecting device 400 detects that the edge of the film 900 generates uneven wrinkles, the supporting roller 600 moves to correct the tension of the edge area of the film 900, so as to avoid the local edge wrinkles of the film 900 wound on the winding roller 300, thereby improving the winding quality of the film 900.

In the process equipment disclosed by the application, tension monitoring and adjustment are real-time dynamic processes. That is, in the case where the data acquired by the detecting device 400 exceeds the preset data range, the controller 500 controls the driving mechanism 800 to drive the supporting roller 600 to start the adjustment. In the case where the data acquired by the detection device 400 is within the preset data range, the driving mechanism 800 stops the tension adjustment. In the case where the device 400 to be detected alarms again, the driving mechanism 800 performs tension adjustment again. Thus, the real-time dynamic adjustment is performed during the entire process of the film 900 transport.

The controller 500 in the process equipment disclosed by the application can be a terminal structure such as a computer, an upper computer and the like, and the specific working principle and structure of the controller 500 are known technologies, and are not limited herein.

In a specific embodiment, the detection device 400 may include a light source and an optical sensor, where the optical sensor is configured to receive light reflected by the film 900 from the light source.

In a specific operation process, the light intensity received by the light sensor may be preset to be within the first light intensity range under the condition of normal tension in the two side edge regions of the film 900. The first light intensity range is the preset data range.

When the edge area of the film 900 has protruding wrinkles, the light intensity received by the light sensor is preset to be a second light intensity range. The second light intensity range is smaller than the first light intensity range because the protrusion of the corrugations increases the reflection angle of the light. When the part of the wind-up roll 300 has the concave fold, the light intensity received by the light sensor is preset to a third light intensity range. The concave reduces the reflection angle of the light rays and has certain light condensing performance, so that the third light intensity range is larger than the first light intensity range. Thus, the tension of the film 900 may be characterized by the intensity of light received by the light sensor.

In another case, since the folds at the edge of the film 900 are generally in a wavy structure with alternately distributed depressions and protrusions, the flatness of the edge of the film 900 can be determined by the received light intensity variation curve.

To better enable tension monitoring of the edge region of the membrane 900, in an alternative embodiment, the detection device 400 may include a first detection member 410 and a second detection member 420. The support roller 600 has a first end 610 and a second end 620, and the first detecting member 410 may be located at a side where the first end 610 is located. The first sensing element 410 may be configured to sense data indicative of tension in an edge region of the membrane material 900 proximate the first end 610. The second detecting element 420 is configured to detect data for characterizing the tension in an edge region of the film 900 near the second end 620.

Specifically, an edge region of the film 900 near the first end 610 may be defined as a first edge region, and the first detecting member 410 may be configured to detect data representing the tension in the first edge region. The edge area of the membrane 900 proximate to the second end 620 may be defined as a second edge area, and the second sensing element 420 may be configured to sense data indicative of tension in the second edge area.

In this scheme, the edge regions at two sides of the membrane 900 are provided with corresponding detection pieces, so that tension detection accuracy of the edge region of the membrane 900 is improved, and tension monitoring of the edge region of the membrane 900 is better achieved.

Alternatively, the first sensing element 410 and the second sensing element 420 may each include a light source and a light sensor.

In another alternative embodiment, the first detecting member 410 and the second detecting member 420 may be distance sensors, and the distance between the first detecting member 410 and the second detecting member 420 and the corresponding edge region of the film 900 is used to characterize the tension. In particular, the distance between the first sensing element 410 and the first edge region may be used to characterize the tension in the first edge region. The distance between the second sensing element 420 and the second edge region may be used to characterize the tension of the second edge region.

In the case that the distance detected by one of the first detecting member 410 and the second detecting member 420 is greater than or less than the preset distance, the controller 500 may control the driving mechanism 800 to drive the supporting roller 600 to move, so as to adjust the relative position of the supporting roller 600, so as to correct the tension of the two side edge regions of the film 900 transferred between the unreeling roller 200 and the reeling roller 300.

In the scheme, the distance sensor has a simple structure, and the manufacturing cost of process equipment is reduced. In addition, the distance sensor can perform more visual measurement on the protrusions and the depressions on the membrane 900, so that the detection reliability is higher.

In the above embodiment, the driving mechanism 800 may drive the supporting roller 600 to translate integrally, so as to calibrate the tension of the edge regions on both sides of the film 900. However, this adjustment has a large influence on the overall tension of the film 900. For example, when the first edge region is wrinkled, the driving mechanism 800 may drive the supporting roller 600 to translate integrally, and at the same time, the tension of the second edge region is also greatly changed while the tension of the first edge region is adjusted, so that the tension of the second edge region is easily excessive, and the second edge region is at risk of breaking or curling.

Based on this, in another alternative embodiment, the driving mechanism 800 may include a first driving unit 810 and a second driving unit 820, the first driving unit 810 being connected with the first end 610 of the support roller 600. The second driving unit 820 is connected to the second end 620 of the support roller 600. The first driving unit 810 may be used to drive the first end 610 of the support roller 600 to move in a direction away from or toward the wind-up roller 300. The second driving unit 820 may be used to drive the second end 620 of the support roller 600 to move in a direction away from or toward the wind-up roller 300.

In a specific operation process, as shown in fig. 3, when the first detecting member 410 detects that the first edge area is wrinkled, the first driving unit 810 drives the first end 610 of the support roller 600 to move in a direction opposite to the film 900, so as to increase the friction between the first end 610 of the support roller 600 and the first edge area, and further cause the first edge area to be stretched. The direction indicated by arrow a in fig. 3 is the transport direction of the film 900, and the direction indicated by arrow B is the moving direction of the first end 610 of the support roller 600.

As shown in fig. 4, when the second detecting member 420 detects that the second edge region is creased, the second driving unit 820 drives the second end 620 of the support roller 600 to move in a direction opposite to the film 900, thereby increasing friction between the second end 620 of the support roller 600 and the second edge region, and further causing the second edge region to be stretched. The direction indicated by arrow a in fig. 4 is the transport direction of the film 900, and the direction indicated by arrow C is the moving direction of the second end 620 of the support roller 600.

In this solution, the first driving unit 810 and the second driving unit 820 disposed at two ends of the supporting roller 600 can realize swinging of the supporting roller 600 towards different positions, so when the tension of the edge area on one side is adjusted, the tension of the edge area on the opposite side is less affected, and the risk of cracking or curling of the edge area on the opposite side is avoided.

Alternatively, the first driving unit 810 and the second driving unit 820 may be linear driving motors or cylinders.

In a specific aspect, the first driving unit 810 may be a first cylinder, and the second driving unit 820 may be a second cylinder. The drive shaft of the first cylinder may be coupled to the first end 610 of the backup roll 600. The driving shaft of the second cylinder may be connected to the second end 620 of the support roller 600.

In the above-mentioned scheme, in order to avoid the backup roller 600 from being killed, a certain active space is required to be reserved for the connection of the first driving unit 810 and the second driving unit 820, so as to reserve a swing margin for the single-side swing of the backup roller 600. However, such a connection is prone to risk of poor driving accuracy.

Based on this, in another alternative embodiment, the first driving unit 810 may be rotatably connected with the first end 610 of the support roller 600. The second driving unit 820 may be rotatably coupled to the second end 620 of the support roller 600. In this scheme, both ends of the support roller 600 are rotatably connected with the first driving unit 810 and the second driving unit 820, respectively, so that the risk of the support roller 600 being locked can be avoided while the single-side swing of the support roller 600 is realized.

In this scheme, the first driving unit 810 and the second driving unit 820 are rotatably connected with the support roller 600, so that the single-side swing can be realized by the rotational connection mode, and therefore, no active space needs to be reserved, so that the single-side swing of the support roller 600 has no reserved swing allowance. The driving accuracy of the support roller 600 can be improved, and thus the risk of tension pulling is avoided.

In a specific embodiment, the drive shaft of the first cylinder may be rotatably coupled to the first end 610 of the support roller 600. The drive shaft of the second cylinder may be rotatably coupled to the second end 620 of the support roller 600. Alternatively, the driving shaft of the first cylinder and the first end 610 of the supporting roller 600 may be rotatably connected by a rotating member such as a rotation shaft, a hinge, or the like. Similarly, the driving shaft of the second cylinder and the second end 620 of the support roller 600 may be rotatably connected by a rotating member such as a shaft or a hinge.

In another alternative embodiment, the first driving unit 810 includes a first driving source 811, a first sliding rail 812, and a first sliding portion 813, and both the first driving source 811 and the first sliding rail 812 may be provided to the rack 100. The first sliding portion 813 is slidably engaged with the first sliding rail 812, and the first sliding portion 813 is connected to the first end 610 of the support roller 600.

The second driving unit 820 may include a second driving source 821, a second slide rail 822, and a second sliding portion 823, each of which is provided to the chassis 100. The second sliding portion 823 may be slidably engaged with the second slide rail 822, and the second sliding portion 823 may be rotatably coupled to the second end 620 of the support roller 600.

In this solution, the first driving unit 810 and the second driving unit 820 both adopt a manner of matching the sliding rail and the sliding block to fixedly mount the supporting roller 600, so that the fixing effect of the supporting roller 600 can be improved, and the reliability of the process equipment is better. At the same time, the movement of the support roller 600 is also made smoother.

The driving source may be connected to the sliding portion by a screw, a worm, or the like, but may be connected by other members, and is not limited herein.

Further, the first driving unit 810 may further include a first universal bearing 814, and the first sliding portion 813 may be connected with the first end 610 of the support roller 600 through the first universal bearing 814. The second driving unit 820 may further include a second universal bearing 824, and the second sliding portion 823 may be connected with the second end 620 of the support roller 600 through the second universal bearing 824.

In this scheme, the universal bearing can realize the swing between the backing roll 600 for the sliding part, and then avoided slide rail and sliding part to take place the dead risk of card, make the clearance between sliding part and the slide rail less simultaneously, consequently make the removal precision of backing roll 600 higher.

Further, the first sliding rail 812 is parallel to the second sliding rail 822. This approach can avoid the risk of the backup roll 600 being killed due to the relative angle of the first and second rails 812, 822. While the first rail 812 is parallel to the second rail 822 also avoids the risk of tilting due to a single side of the support roller 600.

In another alternative embodiment, both the first driving source 811 and the second driving source 821 may be servo motors. In the scheme, the servo motor has the advantages of accurate position precision, high reaction speed and the like, so that the reaction speed and the precision of tension adjustment of process equipment can be further improved.

In the above embodiment, the process apparatus may further include an encoder 700, and the detecting device 400 may be connected to the controller 500 through the encoder 700. Encoder 700 is a device that compiles, converts, or otherwise converts signals or data into a form of signals that can be used for communication, transmission, and storage. The data detected by the detecting means 400 at this time is transferred to the controller 500 through the encoder 700.

In one aspect, the first sensing element 410 and the second sensing element 420 may be positioned on both sides of the support roller 600, respectively. At this time, the first and second detecting members 410 and 420 are staggered in the width direction of the film 900. At this time, since the first and second sensing members 410 and 420 are relatively far apart, it is inconvenient to simultaneously install and maintain the first and second sensing members 410 and 420.

In another alternative embodiment, the first detecting member 410 and the second detecting member 420 may be located on the same side of the supporting roller 600, the first detecting member 410 and the second detecting member 420 are arranged in a direction parallel to the axial direction of the wind-up roller 300, and the first detecting member 410 and the second detecting member 420 are located at the same height. In this solution, the first detecting element 410 and the second detecting element 420 are arranged along the width direction of the film 900, and the heights of the first detecting element 410 and the second detecting element 420 are the same, so that the first detecting element 410 and the second detecting element 420 are in the same transverse installation space, thereby facilitating the simultaneous installation and maintenance of the first detecting element 410 and the second detecting element 420, and reducing the labor intensity of operators.

In another alternative embodiment, the frame 100 may be provided with a guide portion, and the extending direction of the guide portion may be parallel to the axis of the wind-up roll 300. The first detecting member 410 and the second detecting member 420 may each be slidably engaged with the guide portion. In this scheme, each detecting member can move along the axial direction of the wind-up roller 300 relative to the base frame and the wind-up roller 300, so that the detecting position of the detecting member can be adjusted, and further, more films 900 with different sizes can be compatible, and therefore, the compatibility of process equipment is improved.

Alternatively, the guiding portion may be a guiding groove, a guiding rod, a guiding rail, or the like, and of course, the guiding portion may be other structures, which are not limited herein. In addition, in order to avoid each detection piece from moving at a preset position, the detection pieces can be locked and fixed by adopting structures such as jackscrews or bolts.

The foregoing embodiments of the present application mainly describe differences between the embodiments, and as long as there is no contradiction between different optimization features of the embodiments, the embodiments may be combined to form a better embodiment, and in view of brevity of line text, no further description is provided herein.

The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and variations of the present application will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the application are to be included in the scope of the claims of the present application.
