Description

Technical Field

[0002] During the cleanroom board production process, an uncoiler is required to unwind the coiled material into individual sheets to provide raw material for subsequent production steps. During the unwinding process, the uncoiler can sometimes cause the individual sheets to shift, affecting the subsequent precise processing of the individual sheets.

[0003] In the prior art, workers rely on the naked eye to observe whether the single sheet released by the uncoiler is offset. Once the offset is found, the operator will use the linear drive mechanism to adjust the position of the uncoiler to achieve the purpose of correction.

[0004] However, when implementing the present invention, the inventors found that manual detection of offset is inefficient and prone to missed detection or misjudgment due to human factors; and when the linear drive mechanism moves the uncoiler, the coil on the uncoiler is prone to wrinkles and deformation, reducing product quality.

[0051] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0052] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.

[0053] The present application realizes automatic deviation correction of the coil 6 through the distance sensor and the driving unit 5 , and ensures the stability of the coil 6 through the pressure roller mechanism 3 and the tensioning mechanism 4 .

[0054] Example 1

[0055] like Figure 1 and Figure 2 As shown, embodiment 1 of the present application provides an uncoiler, comprising:

[0056] Frame 1, mounting structure 2, pressing roller mechanism 3, tensioning mechanism 4, driving unit 5 and distance sensor (not shown in the figure).

[0057] The mounting structure 2 is connected to the frame 1 in a sliding manner along a first direction; the pressure roller mechanism 3 is connected to the mounting structure 2 in a rotational manner around the first direction, and the pressure roller mechanism 3 is used to roll in contact with the outer side of the coil 6 and apply pressure; the first end of the tensioning mechanism 4 is connected to the mounting structure 2 in a rotational manner around the first direction, and the tensioning mechanism 4 is used to apply pressure to the inner side of the coil 6; the driving unit 5 is connected to the frame 1 and the mounting structure 2 respectively, and the driving unit 5 is used to drive the mounting structure 2 to move along the first direction; the distance sensor is connected to the driving unit 5 by signal; the detection end of the distance sensor is used to be opposite to the side of the raw material formed after the coil 6 is released; the distance sensor is used to detect the distance from the side of the raw material and generate a first signal, and the driving unit 5 can obtain the first signal and work based on the first signal.

[0058] Specifically, the frame 1 provides a solid supporting structure for the entire uncoiler, and the frame 1 is used to install the driving unit 5 and the mounting structure 2. The specific structure of the frame 1 can be specifically designed according to actual needs.

[0059] The mounting structure 2 is used to support the pressure roller mechanism 3 and the tensioning mechanism 4. The uncoiler may further include a guide rail provided on the frame 1, the guide rail extending along a first direction, and the mounting structure 2 is slidably connected to the frame 1 along the first direction via the guide rail to ensure smooth and precise movement of the mounting structure 2.

[0060] The pressure roller mechanism 3 ensures that the coil 6 moves synchronously with the mounting structure 2 when the mounting structure 2 moves in the first direction by rolling contact and applying pressure to the outer side of the coil 6. This prevents the coil 6 from wrinkling, deforming, or other undesirable conditions caused by the movement of the mounting structure 2, thereby ensuring the stability of the coil 6 during the deflection correction process. The pressure roller mechanism 3 may include a roller, a connector, and a spring. The two ends of the spring are respectively connected to the mounting structure 2 and the connector. The roller is connected to the connector so as to rotate about the first direction. The spring can be extended and retracted perpendicular to the outer side of the coil 6. The spring is always in a compressed state, allowing the roller to continuously roll and apply pressure to the outer side of the coil 6 during the unwinding process, ensuring smooth and accurate unwinding of the coil 6. The rolling contact between the roller and the outer side of the coil 6 also reduces friction on the coil 6, thereby ensuring the quality of the coil 6. The connector can be slidably connected to the mounting structure 2 along the spring's extension and retraction direction to ensure the stability of the pressure roller mechanism 3.

[0061] The coil 6 can be mounted on the tensioning mechanism 4. The tensioning mechanism 4 applies pressure to the inner side of the coil 6 to ensure that the coil 6 can move synchronously with the mounting structure 2 when the mounting structure 2 moves, preventing the coil 6 from wrinkling, deforming, or other undesirable conditions caused by the movement of the mounting structure 2. This ensures the stability of the coil 6 during the deviation correction process. It also ensures that the coil 6 remains taut and stable during the unwinding process, preventing wrinkles and deformation caused by the loosening of the coil 6, thereby ensuring stability during the unwinding process. The tensioning mechanism 4 may include an air shaft and a servo motor. The servo motor is disposed on the mounting structure 2. The first end of the air shaft is connected to the servo motor. The servo motor is used to drive the air shaft to rotate about a first direction to unwind the coil 6 mounted on the air shaft. The air shaft can adjust its diameter by changing the air pressure to apply pressure to the inner side of the coil 6. The specific structure of the air shaft is known to those skilled in the art and will not be described in detail here.

[0062] The drive unit 5 is used to provide power, enabling the mounting structure 2 to move accurately and smoothly along the first direction. The drive unit 5 can be mounted on the frame 1 by bolts or a clamping connection, and the driving end of the drive unit 5 can be connected to the mounting structure 2 by a pin or bolt. The drive unit 5 can be a linear motor, a hydraulic cylinder, a pneumatic cylinder, etc.

[0063] The distance sensor is used to detect the distance from the side of the raw material formed after the coil 6 is unwound. After the equipment is started or the coil 6 is replaced, the uncoiler can be initially calibrated. At this time, the coil 6 is placed in the correct position, and the distance from the raw material detected by the distance sensor is set as the reference value or zero point. During the unwinding process of the coil 6, the distance sensor monitors the distance from the side of the raw material in real time. The distance sensor compares the real-time monitored distance value with the reference value during the initial calibration. If there is a difference between the real-time monitored distance value and the reference value, and this difference exceeds the preset tolerance range, the coil 6 is deemed to have deviated and a first signal is generated. The control method of the distance sensor, including initial calibration, real-time monitoring, comparison, and deviating judgment, is a technology familiar to those skilled in the art and does not require creative work. The distance sensor can be set on the frame 1. The distance sensor can be a photoelectric sensor, a laser distance sensor, etc.

[0064] Compared with the existing technology, the uncoiler provided in this application uses a distance sensor to detect the distance from the side of the raw material to realize automatic detection of the offset of the raw material. Once the offset is detected, the distance sensor generates a first signal, and the driving unit 5 drives the mounting structure 2 to slide in the first direction based on the first signal, thereby realizing automatic correction of the coil 6 on the mounting structure 2, thereby improving the efficiency and accuracy of the correction.

[0065] The pressure roller mechanism 3 and the tensioning mechanism 4 provided on the mounting structure 2 apply pressure to the outer side and the inner side of the coil 6 respectively, thereby ensuring the stability of the coil 6 during the sliding process of the mounting structure 2, preventing the coil 6 from wrinkling, deformation and other adverse conditions due to the movement of the mounting structure 2, and ensuring the quality of the coil 6; and, during the unfolding process of the coil 6, the coordinated action of the pressure roller mechanism 3 and the tensioning mechanism 4 also ensures the stability of the coil 6, ensuring that the coil 6 can be unfolded smoothly and accurately, so that the raw materials released by the coil 6 can enter the subsequent production process in a flat state.

[0066] like Figure 2 and Figure 3 As shown, in some embodiments, the mounting structure 2 includes:

[0067] The mounting seat 21 is slidably connected to the frame 1 along the first direction, and the first ends of the pressing roller mechanism 3 and the tensioning mechanism 4 are both rotatably connected to the mounting seat 21 around the first direction; the driving unit 5 is connected to the mounting seat 21;

[0068] The bearing portion 22 and the mounting seat 21 are arranged along the first direction; the bearing portion 22 is movably connected to the frame 1 , and the bearing portion 22 is used to support the second end of the tensioning mechanism 4 .

[0069] Specifically, the mounting seat 21 can be slidably connected to the frame 1 along a first direction via a guide rail. The specific structure of the mounting seat 21 can be specifically designed according to actual needs. The bearing portion 22 can be detachably connected to the frame 1 to enable the loading of the coil 6 on the tensioning mechanism 4. The bearing portion 22 can be in the shape of a plate or a block, etc. The bearing portion 22 can be used to support the second end of the pneumatic shaft to maintain the stability of the tensioning mechanism 4 during the movement of the mounting seat 21, while also improving the stability of the tensioning mechanism 4 during the unwinding process, ensuring the smooth unwinding of the coil 6.

[0070] like Figure 2 and Figure 3 As shown, in some embodiments, the carrier portion 22 includes:

[0071] The carrier 221 is movably connected to the frame 1;

[0072] The roller assembly 222 is connected to the bearing member 221 for rotation around the first direction. The roller assembly 222 is used to support the second end of the tensioning mechanism 4. The rotation of the tensioning mechanism 4 can drive the roller assembly 222 to rotate.

[0073] Specifically, the bearing portion 22 may further include a gantry 223 and a locking assembly. The gantry 223 is connected to the frame 1 for rotation about a third direction, with the third direction, the first direction, and the second direction being perpendicular to each other. The locking assembly is connected to the gantry 223 and the frame 1, respectively, and is used to limit the rotation of the gantry 223. The bearing member 221 is disposed on the gantry 223. The rotation of the gantry 223 enables the bearing member 221 and the roller assembly 22 to avoid each other, thereby enabling the loading of the coil 6 on the tensioning mechanism 4. The locking assembly may be a locking bolt or a hook assembly. The uncoiler 100 may further include a loading trolley 7, which is directly opposite the mounting seat 21 in the first direction and is used to carry and transport the coil 6 along the first direction to enable the loading of the coil 6.

[0074] The first end of the support member 221 rotates the roller assembly 222 in a first direction. The support member 221 can be fixedly mounted on the gantry 223; alternatively, the support member 221 can have external threads, and the gantry 223 can have threaded holes extending therethrough in a third direction. The support member 221 is threadedly connected to the gantry 223 via the threaded holes to adjust the position of the roller assembly 222, enabling it to support pneumatic shafts of varying sizes and improving its adaptability. The rotation of the tensioning mechanism 4 drives the rotation of the roller assembly 222, reducing friction between the tensioning mechanism 4 and the roller assembly 222, thereby extending the service life of both components.

[0075] The roller assembly 222 may include one roller or two rollers; or Figure 2 and Figure 3 As shown, in some embodiments, the roller assembly 222 includes:

[0076] At least three rollers are arranged at intervals along the arc track; at least three of the rollers together form a discontinuous arc-shaped bearing surface, which is adapted to the shape of the second end of the tensioning mechanism 4. The bearing surface can limit the movement of the tensioning mechanism 4 along a second direction, which is perpendicular to the first direction.

[0077] Specifically, each roller is capable of contacting the second end of the tensioning mechanism 4. At least one roller is located on a first side of the axis of the tensioning mechanism 4 along the second direction, and at least one roller is located on a second side of the axis of the pneumatic shaft along the second direction. This allows the bearing surface to restrict movement of the pneumatic shaft in the second direction, ensuring the movement path of the tensioning mechanism 4 as it moves along the mounting base 21 along the first direction. The bearing surface is adapted to the shape of the second end of the pneumatic shaft, enhancing the stability of the tensioning mechanism 4 as it moves along the mounting base 21 and ensuring that the tensioning mechanism 4 remains stable during the unwinding process.

[0078] like Figure 2 and Figure 4 As shown, in some embodiments, the pressing roller mechanism 3 includes:

[0079] A first driving member 31 is provided on the mounting structure 2;

[0080] The pressure roller 32 is connected to the driving end of the first driving member 31 and rotates around the first direction. The first driving member 31 is used to drive the pressure roller 32 to move closer to or away from the coil 6.

[0081] Specifically, the pressing roller mechanism 3 may further include a bearing, and the pressing roller 32 is connected to the driving end of the first driving member 31 via the bearing. In order to improve the accuracy of the pressing roller mechanism 3, the pressing roller mechanism 3 may further include a rotating shaft 33 and a mounting member 34. The first end of the rotating shaft 33 is rotatably connected to the mounting seat 21 around the first direction, and the second end of the rotating shaft 33 is rotatably connected to the pressing roller 32 around the first direction via the bearing. The mounting member 34 is provided on the side wall of the rotating shaft 33. The driving end of the first driving member 31 is rotatably connected to the mounting member 34 around the first direction. The first driving member 31 drives the mounting member 34 to reciprocate along the third direction, which can drive the rotating shaft 33 to rotate forward and reverse around the first direction. When the rotating shaft 33 rotates forward around the first direction, the pressing roller 32 on the rotating shaft 33 approaches the coil 6, so that the pressing roller 32 can continuously apply pressure to the outer side of the coil 6 during unwinding. When the rotating shaft 33 rotates reversely around the first direction, the pressing roller 32 on the rotating shaft 33 moves away from the coil 6, so that the unwinder can be loaded. The first driving member 31 can be a linear motor, a hydraulic cylinder or a pneumatic cylinder.

[0082] like Figure 2 、 Figure 5 and Figure 6 As shown, in some embodiments, the tensioning mechanism 4 includes:

[0083] A hollow shaft 41, a first end of which is rotatably connected to the mounting structure 2 around the first direction;

[0084] A second driving member 42 is provided on the mounting structure 2;

[0085] A transmission shaft, the hollow shaft 41 is sleeved on the transmission shaft, both ends of the transmission shaft extend out of the hollow shaft 41, and the first end of the transmission shaft is connected to the second driving member 42;

[0086] The wedge-shaped structure 43 is connected to the second end of the transmission shaft for rotation around the first direction. The wedge-shaped structure 43 is connected to the outer wall of the hollow shaft 41 for sliding along the first direction. The second driving member 42 drives the wedge-shaped structure 43 to reciprocate along the first direction through the transmission shaft, so that the wedge structure 43 can approach or move away from the inner side of the coil 6.

[0087] Specifically, the first end of the hollow shaft 41 can be rotatably connected to the mounting seat 21 in a first direction via a bearing, and the bearing portion 22 is used to support the second end of the hollow shaft 41. The wedge structure 43 includes a first wedge block 431, a second wedge block 432, and a fixing member 433. The first wedge block 431 can be rotatably connected to the second end of the transmission shaft in the first direction via a bearing. The first side of the first wedge block 431 can be slidably connected to the outer wall of the hollow shaft 41 in the first direction via a sliding sleeve. The second side of the first wedge block 431, which is opposite to the first side, has a first inclined surface, and the first inclined surface has an acute angle with the first direction. The fixing member 433 is disposed on the main shaft. The second wedge block 432 is slidably connected to the fixing member 433 along the radial direction of the hollow shaft 41. The first side of the second wedge block 432 is used to contact and apply pressure to the inner side of the coil 6. The second side of the second wedge block 432, which is opposite to the first side, has a second inclined surface, which is parallel to and in contact with the first inclined surface. The second driving member 42 drives the first wedge block 431 to reciprocate in a first direction via a transmission shaft, causing the second wedge block 432 to move closer to or further away from the inner side of the coil 6. To ensure uniform force, the wedge structure 43 may further include a tensioning plate 434. The first side of the first wedge block 431 is connected to the tensioning plate 434, which contacts and applies pressure to the inner side of the coil 6.

[0088] The number of wedge-shaped structures 43 can be one, two, three or even more. When there are one or two wedge-shaped structures 43, the coil 6 can be a coil 6 that does not require high tension uniformity, such as packaging materials, plastic films or cloth, etc.; when the number of wedge-shaped structures 43 is at least three, at least three wedge-shaped structures 43 are arranged at equal intervals along the circumferential trajectory to improve the overall tension uniformity of the coil 6.

[0089] like Figure 2 、 Figure 5 and Figure 7 As shown, in some embodiments, the tensioning mechanism 4 further includes:

[0090] A third driving member 44 is provided on the mounting structure 2;

[0091] The transmission assembly 45 is located between the wedge structure 43 and the second driving member 42; the transmission assembly 45 is connected to the third driving member 44 and the outer wall of the hollow shaft 41 respectively; the third driving member 44 drives the hollow shaft 41 to rotate around the first direction through the transmission assembly 45.

[0092] Specifically, the transmission assembly 45 can be a chain transmission assembly or a gear transmission assembly, etc., and the present application prefers the more cost-effective chain transmission assembly. The chain transmission assembly can include a first sprocket 451, a second sprocket 452, and a chain ring 453. The first sprocket 451 is fixedly mounted on the hollow shaft 41 and is located between the wedge structure 43 and the second driving member 42. The second sprocket 452 is fixedly mounted on the driving end of the third driving member 44, with the second sprocket 452 and the first sprocket 451 facing each other, and the chain ring 453 meshes with the first sprocket 451 and the second sprocket 452. By arranging the transmission assembly 45 between the wedge structure 43 and the second driving member 42, a compact structural layout is achieved, reducing the overall space occupied by the equipment.

[0093] like Figure 5 As shown, in some embodiments, the hollow shaft 41 has a connecting section, which is located between the wedge structure 43 and the transmission assembly 45, and the connecting section is connected to the mounting structure 2 for rotation around the first direction.

[0094] Specifically, the connecting section of the hollow shaft 41 can be rotatably connected to the mounting seat 21 around the first direction via a bearing. The connecting section makes the hollow shaft 41 more stable during operation, reduces vibration, and improves the stability of the entire system.

[0095] Example 2

[0096] like Figure 1 and Figure 2 As shown, Example 2 of the present application provides a production line, comprising:

[0097] The uncoiler 100 of Example 1 includes:

[0098] Frame 1;

[0099] A mounting structure 2, slidably connected to the frame 1 along a first direction;

[0100] a pressure roller mechanism 3, rotatably connected to the mounting structure 2 about the first direction, the pressure roller mechanism 3 being configured to roll in contact with the outer side of the coil 6 and apply pressure;

[0101] a tensioning mechanism 4, a first end of which is rotatably connected to the mounting structure 2 about the first direction, and the tensioning mechanism 4 is used to apply pressure to the inner side of the coil 6;

[0102] a driving unit 5 connected to the frame 1 and the mounting structure 2, respectively, and configured to drive the mounting structure 2 to move along the first direction;

[0103] A distance sensor is connected to the drive unit 5 by signal; the detection end of the distance sensor is used to be opposite to the side of the raw material formed after the coil 6 is released; the distance sensor is used to detect the distance from the side of the raw material and generate a first signal, and the drive unit 5 can obtain the first signal and work based on the first signal.

[0104] Specifically, the number of the uncoilers 100 may be one or more. When there are more than one uncoiler 100 , the multiple uncoilers 100 may be arranged at intervals along the second direction to achieve continuous production during the production process.

[0105] The production line of Example 2 of the present application includes the uncoiler 100 of Example 1. The uncoiler 100 uses a distance sensor to detect the distance from the side of the raw material to automatically detect the offset of the raw material. Once the offset is detected, the distance sensor generates a first signal. The drive unit 5 drives the mounting structure 2 to slide in the first direction based on the first signal, thereby realizing automatic correction of the coil 6 on the mounting structure 2, thereby improving the efficiency and accuracy of the correction.

[0106] The pressure roller mechanism 3 and the tensioning mechanism 4 provided on the mounting structure 2 apply pressure to the outer side and the inner side of the coil 6 respectively, thereby ensuring the stability of the coil 6 during the sliding process of the mounting structure 2, preventing the coil 6 from wrinkling, deformation and other adverse conditions due to the movement of the mounting structure 2, and ensuring the quality of the coil 6; and, during the unfolding process of the coil 6, the coordinated action of the pressure roller mechanism 3 and the tensioning mechanism 4 also ensures the stability of the coil 6, ensuring that the coil 6 can be unfolded smoothly and accurately, so that the raw materials released by the coil 6 can enter the subsequent production process in a flat state.

[0107] like Figure 8 As shown, in some embodiments, it also includes:

[0108] The transmission mechanism 200 is used to transmit the raw materials, and the distance sensor is provided on at least one side of the transmission mechanism 200 .

[0109] Specifically, the transmission mechanism 200 may be a horizontal transmission mechanism; or, the transmission mechanism 200 may be an inclined transmission mechanism to achieve non-horizontal transmission of raw materials.

[0110] When the production line of the present application is used for the production of clean boards, the conveyor mechanism 200 may include two inclined conveyor mechanisms 200, which are arranged at intervals along the third direction. In this case, there are multiple uncoilers 100, with at least two uncoilers 100 arranged along the third direction to respectively convey raw materials to the two conveyor mechanisms 200.

[0111] The distance sensor can be installed on at least one side of the conveyor mechanism 200 using a clamp, snap-on connection, or other means. The distance sensor installed on the conveyor mechanism 200 can continuously monitor the status of the raw materials during transportation, facilitating real-time monitoring of the raw materials' transportation status and providing more comprehensive and continuous monitoring. The number of distance sensors can be one or more. If multiple distance sensors are used, they can be installed on both sides of the conveyor mechanism 200 in the width direction to ensure the accuracy of the final detection results.

[0112] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
