We provide a film deviation correction system that corrects the deviation of film. [Solution] The system includes a first guide member 11 having a first suction-capable guide belt 111 and a first horizontal moving member 112, a second guide member 12 having a second suction-capable guide belt 121 and a second horizontal moving member 122, at least one sensor, and a controller. The first and second suction-capable guide belts form a film transport path, allowing the film to pass sequentially through the first and second guide members. When the controller receives a position signal of the film 5 detected and output by the sensor, it adjusts and controls the suction state of the film by the first and second suction-capable guide belts, and adjusts and controls the first and second horizontal moving members to adjust the relative position between the first and second suction-capable guide belts, thereby correcting the deviation of the film's position.

Description

Technical Field

[0001] The present invention relates to an offset correction system, and particularly to a film offset correction system that continuously corrects the offset of a film in multiple stages.

Background Art

[0002] Film-like materials are very common and widely used in industrial manufacturing processes. For example, they are used as main components of major products (such as various composite films), or protective layers of products (such as anti-scratch protective films for mirrors), or reinforcing materials for product components in the manufacturing process (such as reinforcing materials for the outer surface of the current collector layer in the battery field). However, there is a most important factor in the above industrial manufacturing process that affects the use of film-like materials. That is the offset of the relative position between the object bonded in the bonding process and the film-like material. Generally, film materials are stored in a form wound around a shaft for convenience in transportation and storage. However, when taking out the film wound around the shaft with equipment, the film may be offset. Therefore, it is necessary to ensure the position accuracy of the material by correcting the offset film in advance with an offset correction device before proceeding to the subsequent production process. If not corrected in advance, the offset film may not be accurately cut in the production process, resulting in size distortion or size errors, and ultimately, a decline in product quality and an impact on the yield may be caused.

[0003] There are currently two known methods for correcting film displacement: one is a displacement correction device, and the other is an edge guide device. However, both of these devices have prerequisites for use. First, the film must have enough tension to be sufficiently stretched on the device's rollers. Second, the film must have enough tensile strength to withstand that tension. Otherwise, effective displacement correction will not be possible. For example, if the film is displaced to the left, the displacement correction device adjusts the tilt angle of the rollers to increase the tension on the left side of the film. At this time, the increased tension on the left side causes the film to experience relatively greater tension on the left side. As a result, the film moves to the right and is corrected to the center position. Also, during the correction process, the rollers of the displacement correction device gradually return to their original positions as the film's position is adjusted.

[0004] When the film has sufficient tensile strength, the above method has the advantage of correcting the film gradually, resulting in a relatively small overall tension difference and less impact on the film's appearance. However, this gradual process has the disadvantage of requiring more time for film correction and resulting in longer film waste. Furthermore, if the film displacement is severe, or even worse, if there is no tension, these displacement correction devices completely lose their film correction function.

[0005] Therefore, there is a need to provide a film displacement correction device that can efficiently correct film displacement without affecting the flatness of the film. [Overview of the project] [Problems that the invention aims to solve]

[0006] In view of the above, the present invention provides a film deviation correction system comprising a first guide member, a second guide member, at least one sensor, and a controller. [Means for solving the problem]

[0007] The first guide member includes a first suction-capable guide belt and a first horizontal moving member. The first horizontal moving member is used to move the first suction-capable guide belt in a horizontal plane. The second guide member includes a second suction-capable guide belt and a second horizontal moving member. The second horizontal moving member is used to move the second suction-capable guide belt in a horizontal plane. The first and second suction-capable guide belts form a film transport path, allowing the film to pass sequentially through the first and second guide members. A sensor is used to detect the position of the film and output a position signal accordingly. A controller is signal-connected to the sensor, the first suction-capable guide belt, the first horizontal moving member, the second suction-capable guide belt, and the second horizontal moving member. Upon receiving a position signal, the controller adjusts and controls the suction state of the film by the first and second suction-capable guide belts, and adjusts and controls the first and second horizontal moving members to adjust the relative position between the first and second suction-capable guide belts, thereby correcting the film's position deviation.

[0008] The first suction-type guide belt includes a first drive roller group and a first conveyor belt, with the first conveyor belt covering the first drive roller group to transmit power. The second suction-type guide belt includes a second drive roller group and a second conveyor belt, with the second conveyor belt covering the second drive roller group to transmit power.

[0009] The first suction-capable guide belt includes a first film suction box, and the first conveyor belt has a plurality of first ventilation holes. The second suction-capable guide belt includes a second film suction box, and the second conveyor belt has a plurality of second ventilation holes. The first and second film suction boxes are signal-connected to a controller in order to adjust and control the suction force on the film by the first film suction box through the first ventilation holes, and to adjust and control the suction force on the film by the second film suction box through the second ventilation holes.

[0010] The first guide member further includes a first frame. The first frame houses a first adhesive guide belt. The first frame has a first supply port and a first discharge port. The second guide member further includes a second frame. The second frame houses a second adhesive guide belt. The second frame has a second supply port and a second discharge port. As a result, the film is guided by the first adhesive guide belt and the second adhesive guide belt as it passes sequentially through the first supply port, the first discharge port, the second supply port, and the second discharge port.

[0011] The first film suction box further includes a first angle adjustment unit. The first angle adjustment unit is signal-connected to a controller. The controller receives a position signal output from the sensor and, based on that, controls the first angle adjustment unit to tilt the first film suction box at a certain angle.

[0012] The second film suction box further includes a second angle adjustment unit. The second angle adjustment unit is signal-connected to a controller. The controller receives a position signal output from the sensor and, based on that, controls the second angle adjustment unit to tilt the second film suction box at a certain angle.

[0013] The film displacement correction system further includes a support frame. The support frame has a first mounting base and a second mounting base. The height of the first mounting base from the bottom end of the support frame is greater than the height of the second mounting base from the bottom end of the support frame. A first guide member is provided on the first mounting base, and a second guide member is provided on the second mounting base.

[0014] The film transport path is at an inclined angle with respect to the bottom surface of the support frame.

[0015] The first horizontal moving member includes a first transfer platform and a first inclined support frame. The bottom end of the first transfer platform is movably joined linearly to a first mounting base. The bottom end of the first inclined support frame is movably joined linearly to the ceiling surface of the first transfer platform. Furthermore, a first suction-capable guide belt is provided on the inclined surface of the first inclined support frame. The direction of movement of the first transfer platform and the direction of movement of the first inclined support frame are perpendicular.

[0016] The second horizontal moving member includes a second transfer platform and a second inclined support frame. The bottom end of the second transfer platform is movably joined linearly to the second mounting platform. The bottom end of the second inclined support frame is movably joined linearly to the ceiling surface of the second transfer platform. Furthermore, a second suction-capable guide belt is provided on the inclined surface of the second inclined support frame. The direction of movement of the second transfer platform and the direction of movement of the second inclined support frame are perpendicular. [Effects of the Invention]

[0017] In summary, the film displacement correction system provided in this invention is applicable to films that are displaced to different degrees and gradually corrects the film to the center position by performing displacement correction in multiple stages. In addition, since the film displacement correction system of this invention employs a method of adsorbing the film with negative pressure, the risk of the film being stretched and deformed during the displacement correction process can be effectively reduced. This ensures the integrity of the film during the displacement correction process. Furthermore, when performing displacement correction with the film displacement correction system of this invention, not only is it possible to avoid deformation of the film, but it also does not affect the corrected portion. As a result, the overall stability and accuracy of the displacement correction process are improved, and overall production efficiency can be increased. [Brief explanation of the drawing]

[0022] Please refer to FIGS. 1, 2, 3 and 4 together. FIG. 1 is a schematic diagram of a film deviation correction system 1 in a specific embodiment of the present invention. FIG. 2 is a schematic diagram of the film deviation correction system 1 in FIG. 1 viewed from another angle. FIG. 3 is a schematic diagram of the conveyance of a film 5 by the film deviation correction system 1 in FIG. 1. FIG. 4 is a schematic diagram of the conveyance of the film 5 by the film deviation correction system 1 in FIG. 3 viewed from another angle. As shown in FIGS. 1, 2, 3 and 4, the film deviation correction system 1 of this specific embodiment includes a first guide member 11, a second guide member 12, a support frame 13, at least one sensor (not shown) and a controller (not shown). The first guide member 11 and the second guide member 12 are provided on the support frame 13 and are used for carrying and conveying the film 5. The sensor is used to detect the position of the film 5 and output a corresponding position signal. The controller is signal-connected to the first guide member 11, the second guide member 12 and the sensor.

[0023] In this specific embodiment, the first guide member 11 includes a first adsorbable guide belt 111 and a first horizontal movement member 112. Also, the first horizontal movement member 112 enables the horizontal movement of the first adsorbable guide belt 111. The first adsorbable guide belt 111 includes a first drive roller group 1111 and a first conveyor belt 1112. Also, the first conveyor belt 1112 is covered over the first drive roller group 1111. In practical use, the first drive roller group 1111 may include a transmission member 1115 and at least two drive rollers 1116. The first conveyor belt 1112 may be an annular conveyor belt that is covered over and contacts the drive roller 1116. The transmission member 1115 enables the drive roller 1116 to rotate, whereby the drive roller 1116 can transmit the first conveyor belt 1112.

[0024] In this specific embodiment, the second guide member 12 includes a second suction-capable guide belt 121 and a second horizontal moving member 122. The second horizontal moving member 122 enables the movement of the second suction-capable guide belt 121 in the horizontal direction. The second suction-capable guide belt 121 includes a second drive roller group 1211 and a second conveyor belt 1212. The second conveyor belt 1212 covers the second drive roller group 1211. In practical use, the second drive roller group 1211 may also include the aforementioned transmission member and at least two drive rollers. The second conveyor belt 1212 may be an annular conveyor belt that covers and contacts the drive rollers. Similarly, the transmission member of the second drive roller group 1211 makes the drive rollers rotatable, thereby enabling the drive rollers to transmit power to the second conveyor belt 1212. Furthermore, in practical use, the controller can connect signals to the transmission members of the first drive roller group 1111 and the second drive roller group 1211 in order to control the operation of the first conveyor belt 1112 and the second conveyor belt 1212.

[0025] In this specific embodiment, the first guide member 11 includes a first frame 113, and the second guide member 12 includes a second frame 123. The first frame 113 has a first accommodation space 1130 for accommodating a first suction-type guide belt 111. Furthermore, a first supply port 1131 and a first discharge port 1132 are provided at both ends of the first frame 113 facing each other. The second frame 123 has a second accommodation space 1230 for accommodating a second suction-type guide belt 121. Furthermore, a second supply port 1231 and a second discharge port 1232 are provided at both ends of the second frame 123 facing each other. In practical use, the first frame 113 is provided on the first horizontal moving member 112, and the second frame 123 is provided on the second horizontal moving member 122. In addition, the first guide member 11 and the second guide member 12 are provided adjacent to each other. Furthermore, the second supply port 1231 of the second frame 123 is compatible with the first discharge port 1132 of the first frame 113. The first supply port 1131, the first suction-capable guide belt 111, the first discharge port 1132, the second supply port 1231, the second suction-capable guide belt 121, and the second discharge port 1232 constitute a film transport path or film transport route in the film displacement correction system 1 of the present invention. The transmission direction of the first transport belt 1112 is from the first supply port 1131 toward the first discharge port 1132, and the transmission direction of the second transport belt 1212 is from the second supply port 1231 toward the second discharge port 1232. Therefore, when the film 5 passes through the first guide member 11 and the second guide member 12, the first suction-capable guide belt 111 and the second suction-capable guide belt 121 can guide and move the film 5.

[0026] Furthermore, in this specific embodiment, the first suction-capable guide belt 111 also includes a first film suction box 1113 provided between the two drive rollers 1116 of the first drive roller group 1111. In this configuration, the first conveyor belt 1112 forms an annular conveyor belt with both ends covering the drive rollers 1116, and the central region of the first conveyor belt 1112 is in close contact with the upper and lower surfaces of the first film suction box 1113. The first conveyor belt 1112 includes a plurality of first ventilation holes 1114. The second suction-capable guide belt 121 further includes a second film suction box 1213 provided between the two drive rollers of the second drive roller group 1211. In this configuration, the second conveyor belt 1212 forms an annular conveyor belt with both ends covering the drive rollers of the second drive roller group 1211, and the central region of the second conveyor belt 1212 is in close contact with the upper and lower surfaces of the second film adsorption box 1213. The second conveyor belt 1212 includes a plurality of second ventilation holes 1214. The first film suction box 1113 and the second film suction box 1213 are signal-connected to a controller. In practical use, the first conveyor belt 1112 covers the first film suction box 1113, and the second conveyor belt 1212 covers the second film suction box 1213. The controller can control the negative pressure generated in the first film suction box 1113 and the second film suction box 1213. As a result, when the film 5 passes through the first guide member 11 and the second guide member 12, the film 5 can be adsorbed onto the surfaces of the first conveyor belt 1112 and the second conveyor belt 1212, respectively, through the first ventilation holes 1114 and the second ventilation holes 1214, thus preventing the film from being stretched and deformed by tension. It should be noted that the force with which the first film suction box 1113 and the second film suction box 1213 draw air is less than the force with which the first conveyor belt 1112 and the second conveyor belt 1212 move the film 5. In other words, the function of the first film suction box 1113 and the second film suction box 1213 is to lightly touch the first conveyor belt 1112 and the second conveyor belt 1212 to make it easier to move the film 5, and not to fix the film 5 on the first conveyor belt 1112 and the second conveyor belt 1212.

[0027] In this specific embodiment, the first film suction box 1113 further includes a first angle adjustment unit 1118, and the second film suction box 1213 further includes a second angle adjustment unit 1218. The first angle adjustment unit 1118 and the second angle adjustment unit 1218 are signal-connected to a controller. In practice, the controller can control the first angle adjustment unit 1118 to control the tilt of the first film suction box 1113. Furthermore, the first film suction box 1113 allows the first suction-capable guide belt 111 to tilt to a certain angle. Similarly, the controller can also control the second angle adjustment unit 1218 to control the tilt of the second film suction box 1213. Furthermore, the second film suction box 1213 allows the second suction-capable guide belt 121 to tilt to a certain angle. This ensures that the film 5 can maintain an appropriate contact angle with the first suction-type guide belt 111 and the second suction-type guide belt 121, and also makes the film 5 flatter, preventing displacement or wrinkles from forming.

[0028] In this specific embodiment, the support frame 13 includes a first mounting base 131 and a second mounting base 132. Furthermore, the height of the first mounting base 131 from the bottom end of the support frame 13 is greater than the height of the second mounting base 132 from the bottom end of the support frame 13. In practical use, the support frame 13 has a stepped structure. The first guide member 11 is provided on the first mounting base 131, and the second guide member 12 is provided on the second mounting base 132.

[0029] In this specific embodiment, the first horizontal moving member 112 includes a first transfer platform 1121 and a first inclined support frame 1122. The bottom end of the first transfer platform 1121 is movably linearly joined to the first mounting base 131. The bottom end of the first inclined support frame 1122 is movably linearly joined to the top surface of the first transfer platform 1121. The first inclined support frame 1122 has an inclined surface, and the first suction-capable guide belt 111 is provided on the inclined surface. In practical use, an X-axis slide rail 141 can be attached to the bottom end of the first transfer platform 1121 in order to movably connect the first transfer platform 1121 to the first mounting base 131. On the other hand, a Y-axis slide rail 142 can be attached to the bottom end of the first inclined support frame 1122 in order to operably connect the first inclined support frame 1122 and the first suction-capable guide belt 111 installed on it to the first transfer platform 1121. As a result, the first guide member 11 can be moved in the X-axis and Y-axis directions, respectively, by the first horizontal moving member 112. Furthermore, the X-axis slide rail 141 and the Y-axis slide rail 142 can be electrically connected to an electric cylinder 143. A controller can be connected to the electric cylinder 143 by signaling to it and control the electric cylinder 143 to move the first guide member 11.

[0030] In this specific embodiment, the second horizontal moving member 122 includes a second transfer platform 1221 and a second inclined support frame 1222. The bottom end of the second transfer platform 1221 is movably linearly joined to the second mounting base 132. The bottom end of the second inclined support frame 1222 is movably linearly joined to the top surface of the second transfer platform 1221. The second inclined support frame 1222 has an inclined surface, and the second suction-capable guide belt 121 is provided on the inclined surface. Similarly, in practical use, an X-axis slide rail 141 can be attached to the bottom end of the second transfer platform 1221 to movably connect the second transfer platform 1221 to the second mounting base 132. On the other hand, a Y-axis slide rail 142 can also be attached to the bottom end of the second inclined support frame 1222 in order to operably connect the second inclined support frame 1222 and the second suction-capable guide belt 121 installed on it to the second transfer platform 1221. This allows the second guide member 12 to move in the X-axis and Y-axis directions, respectively, by the second horizontal moving member 122. Similarly, the X-axis slide rail 141 and the Y-axis slide rail 142 can be electrically connected to an electric cylinder 143. The controller can be signaled to the electric cylinder 143 and control the electric cylinder 143 to move the second guide member 12.

[0031] In this specific embodiment, the sensor is provided above the first guide member 11 and the second guide member 12, and is connected to the controller to detect the position of the film 5 and immediately transmit the detected position signal to the controller. For example, when the sensor detects the displacement distance of the film 5 from the center line, it generates a position signal of the film 5 and transmits the position signal to the controller. When the controller receives a signal, it drives the corresponding electric cylinder 143 to move the corresponding guide member in the X-axis direction and / or Y-axis direction to correct the position of the displaced film 5. In one specific embodiment, the first guide member and the second guide member may each include a plurality of sensors. Furthermore, the sensors may be provided at a plurality of different positions and angles to detect the position of the film and output a position signal. The controller can adjust and correct the position of the film by at least one of the horizontal moving member, film suction box, and angle adjustment unit described above.

[0032] In actual use, if the displacement of the film 5 is relatively small, the displacement correction can be completed in a single adjustment. For example, consider a case where the total travel distance controllable by the electric cylinder 143 is 80 mm (i.e., it can move 40 mm to the left and right on the x-axis), and the displacement correction is first performed using the second guide member 12 during the displacement correction process. In this case, the first guide member 11 brings the first conveyor belt 1112 into contact with the film 5 using only one drive roller 1116 (as shown in Figure 4). When the sensor detects that the film 5 is shifted 30 mm to the left from the center, it transmits the detected signal to the controller. The controller then controls the electric cylinder 143 to move the second guide member 12 in the opposite direction (i.e., to the right) to perform the displacement correction. During the displacement correction process, the second guide member 12 holds the film 5 in place while the electric cylinder 143 moves the second guide member 12 along the X-axis slide rail 141. When the second guide member 12 moves 30 mm to the right, the film 5 is corrected to its center position. At this point, the sensor detects the position of the film 5 again and, upon confirming that it is already centered, the controller further adjusts the first guide member 11. Specifically, the first angle adjustment unit 1118 adjusts the tilt angle of the first film suction box 1113, and the electric cylinder 143 moves the first guide member 11 along the Y-axis slide rail 142, thereby smoothly transferring the film 5 to the first guide member 11. Then, after the first suction-capable guide belt 111 of the first guide member 11 has completely adsorbed the film 5, the controller adjusts the second angle adjustment unit 1218 of the second guide member 12 to tilt the second suction-capable guide belt 121 of the second guide member 12, so that it comes into contact with the film 5 by only one drive roller and is adsorbed. This ensures that the film 5 to be corrected is not affected by the second guide member 12 after it has moved to the first guide member 11, thus avoiding unnecessary displacement. It should be noted that the size of the second guide member 12 is smaller than the size of the first guide member 11 in order to smoothly transfer the film 5 during the displacement correction and transport process and to minimize changes in tension.

[0033] If the deviation of the film 5 is relatively large, it is necessary to perform deviation correction in stages. For example, suppose the sensor detects that the position of the film 5 is off-center by 70 mm, which is more than half of the total travel distance of the electric cylinder 143, which is 80 mm. In this case, it is impossible to completely correct the film 5 in one step using only one guide member. Therefore, the deviation correction process must be performed sequentially by the first guide member 11 and the second guide member 12. The controller drives the first set of guide members (for example, the second guide member 12) and moves the second guide member 12 toward the center by 40 mm (i.e., the maximum movable distance of the electric cylinder 143) using the electric cylinder 143, thereby reducing the displacement of the film 5 to 30 mm as an initial step. After the second guide member 12 has completed the initial correction, the controller synchronously adjusts the second set of guide members (for example, the first guide member 11) to perform displacement correction. In other words, the first angle adjustment unit 1118 is adjusted to change the inclination angle of the first suction-type guide belt 111 and moves it to the appropriate position along the Y-axis slide rail 142, thereby taking over the displacement correction of the film 5. At this point, when the sensor detects the position of the film 5 again and confirms that the remaining displacement is 30 mm, the controller controls the electric cylinder 143 to move the first guide member 11 to correct by another 30 mm, thereby returning the film 5 completely to the center position.

[0034] If the film 5 is displaced by a large amount, for example, 100 mm from the center, it is necessary to perform stepwise displacement correction using the first guide member 11 and the second guide member 12. The controller drives the first set of guide members (e.g., the second guide member 12) and moves the second guide member 12 40 mm toward the center using the electric cylinder 143, thereby reducing the amount of displacement of the film 5 to 60 mm. After the second guide member 12 has completed the initial correction, the second set of guide members (e.g., the first guide member 11) performs a further 40 mm displacement correction, reducing the amount of displacement to 20 mm. Finally, the controller has the first set of guide members perform a final adjustment again, correcting the remaining 20 mm of displacement to return the film completely to the center position. Therefore, even if the amount of displacement of the film 5 exceeds the total travel distance of the electric cylinder 143, the film can be corrected by performing displacement correction in multiple stages. Furthermore, when performing deviation correction using the film deviation correction system of the present invention, no deformation occurs in the film, nor does it affect the corrected portion of the film, thus ensuring the overall stability and accuracy of the deviation correction process. It should be noted that in the above embodiment, the second guide member 12 was used as the first set of guide members, but the order in the film transport direction is not limited to the above, and the first guide member 11 may also be used as the first set of guide members.

[0035] In summary, the film displacement correction system provided in this invention is applicable to films that are displaced to different degrees and gradually corrects the film to the center position by performing displacement correction in multiple stages. In addition, since the film displacement correction system of this invention employs a method of adsorbing the film with negative pressure, the risk of the film being stretched and deformed during the displacement correction process can be effectively reduced. This ensures the integrity of the film during the displacement correction process. Furthermore, when performing displacement correction with the film displacement correction system of this invention, not only is it possible to avoid deformation of the film, but it also does not affect the corrected portion, thus improving the overall stability and accuracy of the displacement correction process and improving overall production efficiency.
