Description

Technical Field

[0001] This invention relates to the field of rewinding machine technology, and in particular to a fully automatic bonding and rewinding machine. Background Technology

[0002] In the fields of electronic appliances, optical film materials and garbage bags, the lamination and rewinding of strips is one of the core production processes. The core of the rewinding process is to rewind the strips into rolls with constant tension and neat end faces, so as to provide raw material rolls with stable dimensions and flat end faces for subsequent automated processing.

[0003] Existing laminating and rewinding machines typically only perform basic unwinding, laminating, and rewinding operations. When the rewinding material folds, loosens, or exhibits abnormal thickness in certain areas during transport, the laminating and rewinding machine cannot resolve winding abnormalities and poor lamination caused by the inability to unfold folded areas. During use, the strip often experiences side folds during rewinding, commonly known as edge folds or folds. Once side folds form, the thickness of the strip in the folded area increases, creating localized bulges or depressions. Due to the abrupt change in thickness, localized high points are formed during winding in the folded area. As the number of winding layers increases, these high points accumulate, forming ridges. In severe cases, this results in uneven end faces of the entire roll of strip. Furthermore, due to the loose interlayer bonding at the folded and recessed areas, interlayer slippage or adhesion can easily occur during subsequent unwinding, further affecting product quality. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic laminating and rewinding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic laminating and rewinding machine, comprising a frame and a rewinding transport channel and a main control module disposed on the frame, and further comprising: A flattening detection unit is disposed on the transmission channel, and the flattening detection unit includes a pressing component and a sensing component arranged sequentially along the transmission direction; The pressing assembly is used to apply adjustable preload pressure to the rewound material before it enters the inspection area to suppress thickness fluctuations caused by material relaxation. The sensing component is used to detect the physical state of the rewinding material in real time and output a state signal after the pressing component applies pre-tightening pressure; The central control module receives the status signal. When the status signal indicates that the physical state parameters of the rewound material exceed a preset threshold, the central control module regulates the action of the execution component of the transmission channel to interrupt the subsequent processing.

[0006] Preferably, the flattening detection unit further includes: A support plate, which is fixed to the frame, is used to provide a supporting plane for the rewinding material; The first extension portion is disposed at the concave end of the bearing plate and has an inclined guide surface for extending and guiding the lower surface of the rewound material. The second extension portion, which is located at the raised end of the support plate, has an arc-shaped guide surface for extending and guiding the upper surface of the rewound material. The pressing component is disposed on the input side of the first extension, and the sensing component is disposed at the detection station of the carrier plate.

[0007] Preferably, the pressing assembly includes a pressing roller and a driving member. The pressing roller is rotatably disposed on the input side of the first extension portion, and the driving member is connected to the pressing roller for driving the pressing roller to move relative to the support plate to adjust the pre-tightening pressure applied to the rewinding material.

[0008] Preferably, the sensing component includes: A floating support member is elastically disposed below the bearing plate and moves as the physical state of the rewound material changes. A sensor is disposed on the displacement path of the floating support and is used to output the status signal to the main control module when the displacement exceeds the preset stroke.

[0009] Preferably, the sensing component further includes a bonding roller that passes through the support plate and is connected to the floating support. The upper surface of the bonding roller is flush with the upper surface of the support plate, and is used to transmit the physical state change of the rewound material to the floating support.

[0010] Preferably, the sensing element includes a fixed part and a movable part, the fixed part is mounted on the frame or the floating support, and the movable part is mounted on the floating support; When the physical state parameters of the rewound material are within the allowable range, the movable part and the fixed part maintain a preset distance; when the physical state parameters of the rewound material exceed the preset threshold, the floating support drives the movable part to move relative to the fixed part to the contact position, triggering the state signal.

[0011] Preferably, the main control module responds to the status signal, locks the drive unit of the transmission channel, and controls the pressing component to release the pre-tightening pressure.

[0012] Preferably, after the main control module locks the drive unit, the action of the pressing component to release the pre-tightening pressure is delayed until the drive unit locks, so as to avoid local tensile deformation of the rewinding material due to residual pre-tightening force in the emergency stop state.

[0013] Preferably, it further includes a bonding component, which is disposed downstream of the flattening detection unit and is used to bond a bonding tape to the surface of the rewound material; Upon receiving the status signal, the central control module synchronously brakes the feeding drive source of the bonding component to pause the release action of the bonding tape.

[0014] Preferably, the central control module includes an interactive interface and an alarm unit; The interactive interface is used to display the physical state parameters detected by the sensing component and the triggering state of the state signal. The alarm unit is used to output warning information when the status signal is triggered, and to allow the main control module to resume the operation of the transmission channel and the bonding component after the status signal is released; After the status signal is triggered, the central control module can only release the locked state of the transmission channel and the bonding component by inputting a manual confirmation command through the interactive interface.

[0015] The technical effects and advantages of this invention are as follows: (1) The present invention applies contact pressure to the strip before it enters the sensing detection area by pressing the attachment component. Combined with the bidirectional extension cooperation of the inclined guide surface of the first extension part and the arc-shaped guide surface of the second extension part, the upper and lower surfaces of the rewound material are applied with stretching forces in opposite directions, which can effectively unfold and smooth the folded area generated at the edge of the strip. This fundamentally eliminates the problems of abnormal winding thickness and uneven end face caused by folding and depression, and achieves tight bonding of the strip during bonding so as not to affect the product quality.

[0016] (2) Based on the lateral position correction of the strip by the correction mechanism, the present invention further uses the contact sensing component formed by the holes and grooves opened on the flat upper surface of the bearing plate and the fitting roller and positioning wheel to detect the physical state of the strip after unfolding in real time. This solves the inherent defect of the existing correction mechanism that can only correct the overall offset of the strip and cannot eliminate the deformation of the folded area, and forms a dual guarantee mechanism of position correction and state detection. (3) The sensing component of the present invention performs contact detection on the physical state of the strip after pre-tightening and stretching guidance. When the folded area is not fully unfolded, the local thickness of the strip exceeds the preset threshold. The floating support drives the moving part of the sensing component to move and triggers an electrical signal. The main control module interrupts the subsequent processing process accordingly, realizing closed-loop control from detection to intervention of folding abnormality. This avoids the folded strip entering the bonding station and causing batch scrap. After detecting the folding abnormality, the main control module simultaneously brakes the feeding drive source of the bonding component and suspends the release action of the bonding tape. This avoids the waste of materials caused by continuing to apply the bonding tape on the folded strip and reduces the loss rate of bonding consumables. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides, for example Figures 1-5 The image shows a fully automatic laminating and rewinding machine.

[0021] Example 1: Includes a frame 101 and a rewinding transport channel and a main control module disposed on the frame 101, and also includes a flattening detection unit 102. The flattening detection unit 102 is disposed on the transport channel. The flattening detection unit 102 includes a pressing component 103 and a sensing component 104 arranged sequentially along the transport direction, and also includes a support plate 121, a first extension 122 and a second extension 123. The support plate 121 is fixed on the frame 101 and is used to provide a supporting plane for the rewinding material. The support plate 121 serves as the supporting base for the rewinding material at the detection station. Its flat upper surface is provided with holes and grooves that are precisely matched with the detection of the sensing component 104. The first extension portion 122 is disposed at the concave end of the support plate 121 and has an inclined guide surface for guiding the extension of the lower surface of the rewound material. The inclined guide surface structure of the first extension portion 122 causes the lower surface of the rewound material to generate an outward tension component under the action of the inclined guide surface before entering the support plate 121. This tension component can initially unfold the slight folds caused by the loosening of the strip edge, thus flattening it. The second extension portion 123 is disposed at the raised end of the support plate 121 and has an arc-shaped guide surface for guiding the extension of the upper surface of the rewound material. The arc-shaped guide surface of the second extension portion 123 causes the upper surface of the rewound material to generate a lateral stretching force along the arc surface before entering the support plate 121. This stretching force effectively eliminates longitudinal wrinkles and folds accumulated in the strip during transmission. The second stretching part 123 and the first stretching part 122 act on the upper and lower surfaces of the rewinding material, respectively, forming a bidirectional stretching cooperation to ensure that the strip enters the pressing area of ​​the pressing assembly 103 in a fully unfolded and flat state. The rewinding material passes sequentially from the second stretching part 123, the first stretching part 122, and the upper surface of the support plate 121 on the flattening detection unit 102. A rotating drum is rotatably connected to one end of the support plate 121 for guiding the rewinding material, facilitating the movement of the rewinding material from the second stretching part 123 to the flattened end of the first stretching part 122. The rotating drum reduces the frictional resistance of the rewinding material during the turning process, avoiding scratches on the strip surface or abnormal tension fluctuations due to excessive friction, while ensuring a smoother transition of the rewinding material between the guide surfaces.

[0022] The pressing assembly 103 is located on the input side of the first extension 122, and the sensing assembly 104 is located at the detection station of the support plate 121. The pressing assembly 103 includes a pressing roller 131 and a driving member 132. The pressing roller 131 is rotatably located on the input side of the first extension 122. The driving member 132 is connected to the pressing roller 131 and is used to drive the pressing roller 131 to move relative to the support plate 121 to adjust the pre-tightening pressure applied to the rewinding material. The pressing roller 131 is rotatably located on the lower surface of the rewinding material. Its rolling contact method can apply pressure to the material without hindering the normal transmission of the material, avoiding surface damage caused by sliding friction. The driving member 132 drives the pressing roller 131 to adjust its height, so that the pressing assembly 103 can adapt to rewinding materials of different thicknesses. At the same time, it can flexibly adjust the contact pressure according to different material characteristics such as material hardness and surface friction coefficient to ensure that the material maintains a stable surface tension state before entering the sensing detection area. The drive component 132 is fixed to the bottom of the frame 101. The drive component 132 is an electric telescopic rod, which features fast response speed and high control precision. It can adjust the position of the pressing roller 131 within milliseconds according to the instructions of the central control module, meeting the requirement of rapid adjustment of the pressing force during high-speed rewinding. The pressing component 103 is used to apply an adjustable pre-tightening pressure to the rewound material before it enters the detection area to suppress thickness fluctuations caused by material relaxation. The application of the pre-tightening pressure ensures that the rewound material is clamped by the pressing roller 131 and the rotating drum before entering the detection area, eliminating thickness fluctuations caused by tension relaxation. This ensures that the material entering the detection station of the sensing component 104 maintains a consistent physical state, effectively avoiding false detection signals caused by material relaxation and improving the accuracy and reliability of the detection results of the sensing component 104.

[0023] During use, the driving component 132 drives the pressing roller 131 to press towards the rotating drum, so that the rewound material between the rotating drum and the pressing roller 131 can be stably pressed, ensuring the thickness of the rewound material is stable.

[0024] In addition, the sensing component 104 is used to detect the physical state of the rewinding material in real time and output a status signal after the pre-tightening pressure is applied by the pressing component 103. The sensing component 104 includes a floating support 141, a sensing element 142 and a bonding roller 143. The floating support 141 is elastically disposed below the bearing plate 121 and moves with the change of the physical state of the rewinding material. The floating support 141 converts the pressure change of the rewinding material transmitted to the bonding roller 143 into its own displacement change by elastic floating, realizing the conversion of the physical quantity of strip thickness into mechanical displacement, and providing a mechanical transmission basis for the triggering of the sensing element 142. The floating support 141 consists of a horizontal plate and multiple limiting rods. The limiting rods are fixed to the lower surface of the bearing plate 121 and slide through the corners of the horizontal plate. A compression spring is fixedly connected to the bottom of the horizontal plate and is sleeved on the bottom of the limiting rod. The elasticity of the compression spring provides elastic support to the horizontal plate. The limiting rods guide and limit the sliding of the horizontal plate, ensuring that the horizontal plate can only move up and down in the vertical direction, avoiding detection position deviation caused by the tilt of the horizontal plate. The compression spring provides a recoverable elastic support force to the horizontal plate, allowing the floating support 141 to sensitively generate corresponding displacement with slight changes in the thickness of the rewound material. At the same time, it can automatically return to the initial position after the material thickness returns to normal. Furthermore, the compression spring can be replaced according to its service life and fatigue, ensuring the repeatability accuracy and long-term stability of the sensing component 104. The sensor 142 is disposed on the displacement path of the floating support 141 and is used to output a status signal to the main control module when the displacement exceeds a preset stroke. The sensor 142 includes a fixed part and a movable part. The fixed part is mounted on the frame 101 or the floating support 141 and is fixed to the frame 101 or between multiple limit rods by an elastic plate. The movable part is mounted on the floating support 141 and is fixed to the lower surface of the horizontal plate in the form of a sensor pen structure. The fixed part and the movable part constitute a displacement detection structure. When the movable part changes its relative distance with the fixed part as the floating support 141 moves, this distance change is converted into a change in electrical signal. The movable part of the sensor pen structure has a sharp contact end, which can form a reliable electrical conduction when in contact with the fixed part, ensuring accurate triggering of the status signal. The elastic plate can be made of elastic rubber. Through the elastic movement of the elastic plate, the hard compression damage of the moving part to the fixed part is avoided. The elastic rubber plate plays a buffering role when the moving part comes into contact with the fixed part, absorbing the excess kinetic energy generated by mechanical vibration or instantaneous impact. This not only protects the physical structure of the sensing element 142 from damage, but also avoids signal errors caused by rigid collisions, thereby improving the reliability and service life of the sensing component 104 in long-term operation.

[0025] The bonding roller 143 passes through the support plate 121 and is connected to the floating support 141. The bonding roller 143 consists of a wheel body and a rotating frame. The wheel body rotates on the rotating frame, which is fixed to the middle of the floating support 141. The upper surface of the bonding roller 143 is flush with the upper surface of the support plate 121, and is used to transmit the physical state changes of the rewound material to the floating support 141. As a direct actuator for contact detection, the bonding roller 143 contacts the lower surface of the rewound material and floats up and down with the thickness of the material. The rolling structure of the bonding roller 143 causes rolling friction between it and the rewound material, avoiding scratches on the material surface and interference with the material transmission speed. The flush arrangement of the upper surface of the bonding roller 143 with the upper surface of the support plate 121 ensures a smooth transition of the rewound material from the support plate 121 to the bonding roller 143, guaranteeing smooth material transfer and allowing thickness changes to be transmitted to the floating support 141 without loss. A positioning wheel is fixedly connected to the top of the bonding roller 143, and is fixed to the inner wall of the frame 101 for fixed-distance movement of the rewound material. The positioning wheel and the bonding roller 143 are positioned opposite each other on the upper and lower sides of the rewound material, forming a fixed detection distance. Determining the distance between the positioning wheel and the bonding roller 143 facilitates the determination of the thickness parameters of the rewound material. When the thickness of the rewound material changes, the downward movement of the bonding roller 143 represents the thickness increment. This defined geometric relationship provides a quantitative physical basis for the detection by the sensing component 104.

[0026] When the physical state parameters of the rewound material are within the allowable range, a preset distance is maintained between the moving part and the fixed part. When the physical state parameters of the rewound material exceed a preset threshold, the floating support 141 drives the moving part to move relative to the fixed part to the contact position, triggering a status signal. The preset distance is set to correspond to the normal fluctuation range of the material thickness. Within this range, the equipment maintains normal operation, avoiding frequent start-ups and shutdowns due to minor fluctuations. When the material thickness exceeds the preset threshold, the moving part and the fixed part contact and conduct, triggering a status signal. This non-contact and contact two-state switching detection method has the advantages of fast response speed, strong anti-interference ability, and high signal reliability, ensuring timely identification and accurate feedback of abnormal states.

[0027] The central control module receives status signals. When the status signal indicates that the physical state parameters of the rewound material exceed a preset threshold, the central control module regulates the action of the actuators in the transmission channel to interrupt the subsequent processing. Responding to the status signal, the central control module locks the drive unit of the transmission channel and controls the pressing assembly 103 to release the pre-tightening pressure. Based on the type and duration of the received status signal, the central control module can accurately determine whether the physical state of the current rewound material meets the processing requirements. In the event of an anomaly, it automatically interrupts processing by regulating the actuators, preventing abnormal materials from entering subsequent workstations and causing batch scrap. This achieves fully automatic closed-loop control from detection to execution.

[0028] After the main control module locks the drive unit, the action of the pressing component 103 releasing the contact pressure is delayed until the locking action of the drive unit is executed. This allows the motion inertia of the rewound material in the emergency stop state to be fully absorbed before the pressing constraint is released. This effectively avoids local tensile deformation or surface scratches caused by the material due to residual pre-tightening force and its own inertial movement, ensuring the integrity of the material under abnormal conditions. After the main control module locks the drive unit, the action of the pressing component 103 releasing the pre-tightening pressure is delayed until the drive unit locks, so as to avoid local tensile deformation of the rewinding material due to the residual pre-tightening force in the emergency stop state. Locking the drive unit stops the transmission of the rewinding material, providing a static operating environment for troubleshooting. At the same time, the pressing component 103 is controlled to release the pre-tightening pressure, so that the rewinding material originally held by the pressing wheel 131 returns to a free state, which makes it easier for the operator to manually flatten the folded material at the abnormal position or remove the abnormal section of material, thus improving the convenience of troubleshooting.

[0029] Example 2: Based on Example 1, it also includes a bonding component 105. The bonding component 105 is located downstream of the flattening detection unit 102 and is used to apply bonding tape to the surface of the rewinding material. The bonding component 105 serves as an existing downstream processing component for the rewinding material. It is used to apply protective tape or functional bonding tape such as double-sided adhesive to the surface of the qualified tape, realizing integrated processing of rewinding and bonding. By placing the bonding component 105 downstream of the flattening detection unit 102, it is ensured that only tape with qualified physical condition can enter the bonding process, thus guaranteeing the bonding quality from the source. After detecting a folding abnormality, the main control module synchronously brakes the feeding drive source of the bonding component 105 and suspends the release action of the bonding tape, avoiding material waste caused by continuing to apply bonding tape on the folded tape and reducing the loss rate of bonding consumables.

[0030] Upon receiving the status signal, the central control module synchronously brakes the feeding drive of the bonding assembly 105 to pause the release of the bonding tape. This synchronous braking mechanism ensures that the release of the bonding tape is synchronized with the stopping of the transmission channel, preventing material accumulation or stretching caused by the bonding tape continuing to release when the transmission channel has stopped. It also avoids waste of bonding tape caused by continuing to bond tape onto tapes with detected abnormalities, thus reducing the wear rate of bonding consumables.

[0031] The central control module includes an interactive interface and an alarm unit. The interactive interface provides operators with a real-time monitoring window for equipment operation status and an entry point for parameter setting. The alarm unit serves as a proactive reminder of abnormal states, ensuring that operators are aware of equipment anomalies immediately, shortening the time delay from anomaly occurrence to manual intervention. The interactive interface displays the physical state parameters and trigger status of the status signals detected by the sensing component 104. The real-time display of physical state parameters and status signal trigger status allows operators to intuitively understand the current rewinding material's test results, facilitating rapid judgment and targeted handling of anomalies. Simultaneously, the display of historical test data allows operators to analyze equipment operating trends and identify potential quality risks in advance. The alarm unit outputs warning information when a status signal is triggered and allows the central control module to resume operation of the transmission channel and bonding component 105 after the status signal is cleared. The alarm unit's warning information output effectively draws the operator's attention, preventing prolonged downtime or abnormal materials flowing to the next process due to the operator's failure to detect anomalies in time. The automatic resumption of operation after the status signal is cleared simplifies the operation process and improves the equipment's resumption efficiency after anomaly resolution. After a status signal is triggered, the main control module can only release the lock on the transmission channel and bonding component 105 by inputting a manual confirmation command through the interactive interface. This manual confirmation reset mechanism serves as a safety interlock for equipment operation, requiring operators to actively confirm the process after troubleshooting before resuming equipment operation. This avoids repeated abnormal processing caused by automatic reset. This mechanism ensures that every abnormal shutdown is manually inspected and intervened, effectively preventing secondary losses caused by incomplete removal of folded material from the processing station, thus improving the safety of equipment operation and the reliability of abnormal handling.

[0032] Example 3: Building upon Example 2, the interactive interface, serving as the core window for human-machine interaction, typically employs a touch-screen industrial display. This display is embedded in the front of the equipment control cabinet or mounted on the operating side of the equipment via a cantilever bracket, facilitating real-time observation and operation by the operator during equipment operation. The interactive interface provides operators with a real-time monitoring window for equipment operation status and an entry point for parameter setting. Operators can set and modify key process parameters such as the pre-tightening pressure value of the pressing component, the detection sensitivity threshold of the sensing component, and the delayed release time parameter through the interactive interface. The alarm unit serves as an active reminder of abnormal states, consisting of an audible and visual alarm and an interface pop-up alarm module. The audible and visual alarm is installed on the top of the equipment or in a prominent position on the rack, ensuring that operators can simultaneously obtain equipment abnormality information from both auditory and visual perspectives at the first moment, shortening the time delay from the occurrence of an anomaly to manual intervention.

[0033] The interactive interface displays the physical state parameters and trigger status of the status signals detected by the sensing component 104. The physical state parameters specifically include the real-time detected thickness of the rewound material, the surface tension fluctuation value of the material at the detection station, and a time curve of the material thickness change. The trigger status of the status signals includes data such as the signal trigger time, signal duration, and cumulative trigger count. The real-time display of these physical state parameters and the trigger status of the status signals allows operators to intuitively understand the current detection results of the rewound material, facilitating rapid identification and targeted handling of anomalies. For example, when the thickness detection value shows a step-like increase, the operator can determine that there is significant folding at the material edge; when the thickness value shows periodic fluctuations, it can be determined that the material itself has periodic thickness unevenness defects, thus allowing for targeted adjustment of the preceding process parameters. Simultaneously, the display of historical detection data also facilitates the operator's analysis of equipment operating trends, enabling early detection of potential quality risks. The interactive interface has a built-in data storage module that can record continuous detection data for the past 24 hours and detailed logs of the last 100 abnormal triggers. Operators can track and analyze the long-term trend of material quality by calling historical data curves, thus realizing the transformation from passive abnormal handling to proactive quality prevention.

[0034] When the alarm unit is triggered by a status signal, it outputs a multi-level warning message: First, a pop-up warning appears on the interface, displaying a flashing red abnormality prompt box and a description of the fault, indicating an abnormal thickness and requesting a check of the folding mechanism. Simultaneously, an audible and visual alarm sounds and a rotating red light illuminates, with the alarm sounding at least 85 decibels to ensure clear visibility to operators even in noisy environments. If the operator does not intervene within 30 seconds during the audible and visual alarm period, the alarm unit will automatically send an abnormality notification to the equipment manager's remote terminal, enabling timely reporting and rapid response to the anomaly. Effective output of the warning message significantly attracts the operator's attention, preventing prolonged downtime or the flow of abnormal materials to the next process due to operator negligence. The design that automatically allows resumption of operation after the status signal is cleared means that when the sensing component detects that the thickness of the rewinding material currently passing through the detection station has returned to the normal value and has remained stable for no less than 3 seconds, the alarm unit automatically clears the audible and visual warning state and allows the main control module to resume equipment operation. This design simplifies the operation process, avoids the need for operators to manually reset and confirm the operation steps, and improves the equipment's resumption efficiency after the anomaly is resolved.

The fixed part is mounted on the frame (101) or the floating support (141), and the movable part is mounted on the floating support (141). When the physical state parameters of the rewound material are within the allowable range, the movable part and the fixed part maintain a preset distance; when the physical state parameters of the rewound material exceed the preset threshold, the floating support (141) drives the movable part to move relative to the fixed part to the contact position, triggering the state signal.

7. The fully automatic laminating and rewinding machine according to claim 6, characterized in that, The main control module responds to the status signal, locks the drive unit of the transmission channel, and controls the pressing component (103) to release the pre-tightening pressure.

8. The fully automatic laminating and rewinding machine according to claim 6, characterized in that, After the main control module locks the drive unit, the action of the pressing component (103) to release the pre-tightening pressure is delayed until the drive unit locks, so as to avoid local tensile deformation of the rewinding material due to the residual pre-tightening force in the emergency stop state.

9. The fully automatic laminating and rewinding machine according to claim 1, characterized in that, It also includes a bonding component (105), which is disposed downstream of the flattening detection unit (102) and is used to bond a bonding tape to the surface of the rewound material; Upon receiving the status signal, the central control module synchronously brakes the feeding drive source of the bonding component (105) to pause the release action of the bonding tape.

10. The fully automatic laminating and rewinding machine according to claim 9, characterized in that, The central control module includes an interactive interface and an alarm unit; The interactive interface is used to display the physical state parameters detected by the sensing component (104) and the triggering state of the state signal; The alarm unit is used to output warning information when the status signal is triggered, and to allow the main control module to resume the operation of the transmission channel and the bonding component (105) after the status signal is released; After the status signal is triggered, the main control module can only release the locked state of the transmission channel and the bonding component (105) by inputting a manual confirmation command through the interactive interface.
