Description

Technical Field

[0001] The present invention relates to the technical field of mirror aluminum production, and in particular to a coating device for a mirror aluminum coil. Background Art

[0002] In the aluminum processing industry, mirror aluminum is widely used in a variety of fields, including building curtain walls, home appliance casings, and automotive interiors, due to its high reflectivity, corrosion resistance, and aesthetics. To protect the surface of the mirror aluminum from scratches, corrosion, and other damage during transportation, it is usually covered with a protective film made of PE or other materials. However, existing mirror aluminum laminating devices face a series of technical difficulties during the laminating process, especially in the critical step of applying the protective film with a pressure roller. Traditional laminating devices mainly use a pressure roller to evenly press the protective film onto the mirror aluminum. However, this pressure roller design has obvious limitations. First, the extrusion range of the pressure roller on the mirror aluminum is usually linear, which means that during the pressing process, the mirror aluminum is subjected to relatively high local pressure. Because mirror aluminum is relatively soft, excessive pressure can easily cause deformation of the mirror aluminum surface, thereby affecting its flatness and reflective properties, and even causing irreversible damage.

[0003] Secondly, mirror aluminum is typically wide and thin, requiring the roller to be precisely adjusted to maintain a perfect fit with the mirror aluminum to ensure the protective film adheres evenly and bubble-free. However, in practice, adjusting the roller becomes extremely complex and difficult, as the thickness of mirror aluminum can vary depending on factors such as production batches and specifications. Operators must rely on extensive experience and sophisticated operating techniques to repeatedly adjust the roller's position and angle to achieve the ideal fit. This not only increases operational difficulty and labor intensity, but also reduces production efficiency and increases product defect rates.

[0004] Therefore, a mirror aluminum coil laminating device is needed to overcome the above problems. Summary of the Invention

[0005] In order to solve the above problems, an embodiment of the present invention provides a laminating device for a mirror-finished aluminum coil, which achieves the purpose of solving the problems raised in the background technology.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the present invention specifically adopts the following technical solutions: a coating device for a mirror aluminum coil, which is used to stick a protective film on the mirror aluminum before it is rolled up, including a frame, a conveying roller for conveying the mirror aluminum is provided on the frame, and a coating assembly for sticking the protective film on the mirror aluminum; the coating assembly includes an inflatable pair of rollers rotatably arranged on the frame for squeezing the mirror aluminum, and a separation assembly provided on the frame for separating the inflatable pair of rollers and the protective film; the inflatable pair of rollers includes a hollow roller shaft rotatably arranged on the frame, a cylindrical airbag fixedly connected to the outside of the hollow roller shaft, a through hole opened on the side wall of the hollow roller shaft for connecting the inside of the hollow roller shaft and the cylindrical airbag, a joint rotatably arranged at the end of the hollow roller shaft, and a connecting pipe provided on the joint for connecting to an air compression pump; after the inflatable pair of rollers presses the protective film onto the mirror aluminum, when the mirror aluminum leaves the inflatable pair of rollers, the separation assembly sprays high-pressure gas to separate the cylindrical airbag and the protective film that are adhered.

[0007] As a further improvement of the above technical solution:

[0008] The separation component includes an air outlet pipe fixedly connected to the frame, an air outlet groove opened on the air outlet pipe, and multiple connecting pipes 2 connected to the air outlet pipe; the multiple connecting pipes 2 converge and connect to the air outlet of the air compression pump.

[0009] The frame is provided with a driving assembly for driving the pneumatic roller to rotate;

[0010] The driving assembly includes two gears respectively fixedly connected to the two hollow rollers and meshing with each other, and a motor installed on the frame for driving one of the hollow rollers to rotate.

[0011] The frame is provided with a material discharging rack for discharging the protective film;

[0012] The unloading rack includes a frame body arranged on the frame for placing the film roll, and a second motor installed on the frame body for driving the film roll to rotate.

[0013] The frame is provided with an identification module for identifying whether the mirror aluminum and the protective film are misaligned; the identification module identifies the mirror aluminum with the protective film attached, and determines whether it is misaligned based on whether the protective film exceeds the side of the mirror aluminum.

[0014] The frame is provided with an adjusting component for adjusting the position of the protective film according to the identification module information; the adjusting component adjusts the position of the protective film by changing the position of the material placing rack.

[0015] The adjustment assembly includes a guide rail arranged on the frame, a screw rod rotatably arranged inside the guide rail, a motor installed at the end of the guide rail for driving the screw rod to rotate, and a slider threadedly connected to the outside of the screw rod and sliding inside the guide rail; the slider is fixedly connected to the bottom of the frame.

[0016] The beneficial effects of the embodiments of the present invention are:

[0017] In actual use, the mirror aluminum and the protective film enter between the two cylindrical airbags, and are thereby extruded by the plane formed by the cylindrical airbags, so that the mirror aluminum extruded by the cylindrical airbags forms a plane; and the plane formed by the deformation caused by the cylindrical airbag extrusion on the mirror aluminum is completely in contact with the surface of the mirror aluminum. At the same time, under the influence of air pressure balance, the pressure at various locations of the plane formed by the cylindrical airbag is balanced, that is, a balanced pressure is applied to the mirror aluminum. That is, when laminating the mirror aluminum, the mirror aluminum is laminating through a plane that is completely in contact with the mirror aluminum and maintains a balanced pressure on various locations of the mirror aluminum. This can avoid the deformation of the mirror aluminum caused by excessive local pressure due to the traditional linear extrusion range.

[0018] In actual use, since the cylindrical airbags can deform on their own after inflation, there is no need to adjust the axial distance between the two cylindrical airbags according to the thickness of the mirror aluminum. When the thickness of the mirror aluminum changes slightly, the cylindrical airbags do not need any adjustment and can adapt to the thickness of the mirror aluminum. When the thickness of the mirror aluminum changes significantly, the inflation pressure of the cylindrical airbags can be adjusted, specifically by reducing or increasing the inflation pressure of the cylindrical airbags. During use, adjusting the inflation pressure is much easier than traditional pressure roller position adjustment, and is convenient for actual production operations.

[0019] In actual use, the protective film is adhered to the mirror aluminum after being squeezed by the cylindrical airbag. When the mirror aluminum leaves the inflatable roller, the cylindrical airbag is likely to pull the protective film, causing the protective film to deform or generate bubbles, affecting the coating quality. Therefore, when the mirror aluminum leaves the inflatable roller, the separation component sprays high-pressure gas to separate the cylindrical airbag and the protective film, avoiding the cylindrical airbag from pulling the protective film, thereby avoiding the problem of affecting the coating quality due to pulling; at the same time, there is a certain angle between the compressed gas sprayed from the air outlet slot and the mirror aluminum, so that the compressed gas can exert a certain pressure on the protective film, making it easier to press the protective film more tightly onto the mirror aluminum through the compressed gas;

[0020] In the present application, a pressure-stabilizing valve is provided to control the air compression pump to inflate the cylindrical airbag, and the inflation of the cylindrical airbag and the air ejection from the air outlet groove share the same air compression pump, which has certain advantages. Specifically, since the air ejection from the air outlet groove needs to be continuous, the air compression pump is in a continuous operation state. When the internal pressure of the cylindrical airbag is lower than the requirement, the pressure reducing valve opens. Since the air compression pump is in a continuous operation state, the compressed gas can enter the interior of the cylindrical airbag through the pressure reducing valve, and the inflation can be quickly responded to, thereby ensuring the internal pressure of the cylindrical airbag is stable.

[0021] If the inflation of the cylindrical airbag and the ejection of the air outlet groove are each performed by an air compression pump, when the pressure of the cylindrical airbag meets the requirement, the air compression pump used for inflating the cylindrical airbag is in a closed state. When the internal pressure of the cylindrical airbag is lower than the requirement, the pressure reducing valve is opened. At this time, a controller is required to control the start of the air compression pump. After the air compression pump is started, it takes a certain amount of time to compress the gas so that the gas pressure is increased. Only then can the cylindrical airbag be inflated. This time is not conducive to the stability of the internal pressure of the cylindrical airbag.

[0022] The frame is provided with an adjustment component for adjusting the position of the protective film according to the information of the recognition module; the adjustment component adjusts the position of the protective film by changing the position of the material rack; when the recognition module uses the machine vision sensor for misalignment detection, when the protective film is misaligned, the machine vision sensor can calculate the misalignment range of the protective film, and thus adjust the position of the material rack through the adjustment component, thereby achieving the purpose of adjusting the position of the protective film and realizing automatic adjustment after the misalignment of the protective film and the mirror aluminum.

[0031] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] See also Figures 1 to 7 The embodiment of the present invention discloses a laminating device for a mirror aluminum coil, which is used to apply a protective film 3 to the mirror aluminum 2 before it is rolled up. The device includes a frame 1, a conveying roller 4 for conveying the mirror aluminum 2, and a laminating assembly 5 for attaching the protective film 3 to the mirror aluminum 2. In actual use, the mirror aluminum 2 is conveyed by the conveying roller 4, and the protective film 3 is attached to the mirror aluminum 2 by the laminating assembly 5, thereby laminating the mirror aluminum 2.

[0033] The laminating assembly 5 includes an air-filled roller 51 rotatably mounted on the frame 1 for squeezing the mirrored aluminum 2 therein, and a separating assembly 52 mounted on the frame 1 for separating the air-filled roller 51 and the protective film 3.

[0034] The inflatable roller 51 includes a hollow roller shaft 511 rotatably mounted on the frame 1, a cylindrical airbag 512 fixedly connected to the outside of the hollow roller shaft 511, a through hole 513 provided on the side wall of the hollow roller shaft 511 for connecting the inside of the hollow roller shaft 511 and the cylindrical airbag 512, a joint 514 rotatably mounted on the end of the hollow roller shaft 511, and a connecting pipe 516 provided on the joint 514 for connecting to an air compressor pump 515.

[0035] After the air compression pump 515 is started, the compressed gas is sent into the interior of the hollow roller 511 through the connecting pipe 1 516. The compressed gas then enters the cylindrical airbag 512 through the through hole 513 opened on the hollow roller 511, thereby achieving the purpose of inflating the cylindrical airbag 512 through the air compression pump 515.

[0036] Two connecting pipes 516 are provided, and the two connecting pipes 516 are respectively connected to the hollow roller shaft 511. The two connecting pipes 516 are connected, that is, the two cylindrical airbags 512 are connected, ensuring that the pressure inside the two cylindrical airbags 512 is the same;

[0037] During actual operation, the two connecting pipes 516 can be connected to each other through a tee and a junction pipe, so that the two connecting pipes 516 are connected through the tee, and the junction pipe is connected to the air outlet of the air compression pump 515. At the same time, a pressure-stabilizing valve can be installed on the junction pipe. After the outlet pressure of the pressure-stabilizing valve is set (the outlet pressure is equal to the inflation pressure inside the cylindrical airbag 512), when the inflation pressure inside the cylindrical airbag 512 meets the requirement, the pressure reducing valve controls the gas to no longer enter the cylindrical airbag 512. When the inflation pressure inside the cylindrical airbag 512 is lower than the requirement, the pressure reducing valve opens to allow the gas to enter the cylindrical airbag 512 for inflation.

[0038] After the air compressor 515 is started, it inflates the cylindrical airbags 512 through the connecting tube 1 516, causing the two cylindrical airbags 512 to expand. When the two cylindrical airbags 512 expand and deform, the two cylindrical airbags 512 abut against each other. Since the internal pressure of the cylindrical airbags 512 is consistent, a plane is formed at the abutting part. The mirror aluminum 2 and the protective film 3 are squeezed from the plane formed by the two cylindrical airbags 512, thereby pressing the protective film 3 against the mirror aluminum 2.

[0039] During actual use, the mirror aluminum 2 and the protective film 3 enter between the two cylindrical airbags 512, and the mirror aluminum 2 and the protective film 3 are squeezed by the plane formed by the cylindrical airbags 512, so that the mirror aluminum 2 squeezed by the cylindrical airbags 512 forms a plane; and the plane formed by the deformation caused by the cylindrical airbags 512 squeezing the mirror aluminum 2 is completely in contact with the surface of the mirror aluminum 2. At the same time, under the influence of air pressure balance, the pressure at various locations of the plane formed by the cylindrical airbags 512 is balanced, that is, a balanced pressure is applied to the mirror aluminum 2. That is, when the mirror aluminum 2 is coated and extruded, the mirror aluminum 2 is coated by a plane that is completely in contact with the mirror aluminum 2 and maintains a balanced pressure on various locations of the mirror aluminum 2. This can avoid the deformation of the mirror aluminum 2 caused by excessive local pressure due to the traditional linear extrusion range.

[0040] In actual use, since the cylindrical airbags 512 can deform on their own after being inflated, there is no need to adjust the axial distance between the two cylindrical airbags 512 according to the thickness of the mirror aluminum 2. When the thickness of the mirror aluminum 2 changes slightly, the cylindrical airbags 512 do not need any adjustment and can adapt to the thickness of the mirror aluminum 2. When the thickness of the mirror aluminum 2 changes greatly, the inflation pressure of the cylindrical airbags 512 can be adjusted, specifically by reducing or increasing the inflation pressure of the cylindrical airbags 512. This is because when the mirror aluminum 2 with increased thickness passes between the two cylindrical airbags 512, the deformation of the cylindrical airbags 512 increases, causing the internal pressure to increase. , which increases the squeezing force of the cylindrical airbag 512 on the mirror aluminum 2. If the thickness of the mirror aluminum 2 changes slightly, the deformation of the cylindrical airbag 512 is small, so the squeezing force of the cylindrical airbag 512 on the mirror aluminum 2 fluctuates slightly. At this time, there is no need to adjust the cylindrical airbag 512. However, if the thickness of the mirror aluminum 2 changes significantly, the deformation of the cylindrical airbag 512 is large, so the squeezing force of the cylindrical airbag 512 on the mirror aluminum 2 fluctuates greatly. In order to avoid the influence of excessive squeezing force on the mirror aluminum 2, it is necessary to appropriately reduce the inflation pressure of the cylindrical airbag 512. When in use, the adjustment of the inflation pressure is much more convenient than the traditional pressure roller position adjustment, which is convenient for actual production operations.

[0041] In actual use, the two cylindrical airbags 512 may have different internal pressures when in use, for example, one of the cylindrical airbags 512 may have intermittent slight air leakage;

[0042] When one of the cylindrical airbags 512 has an intermittent slight air leak, the internal pressure of the cylindrical airbag 512 decreases. Since the two cylindrical airbags 512 are connected, the gas inside the other cylindrical airbag 512 with a higher internal pressure will enter the other cylindrical airbag 512 with a higher internal pressure through the connecting tube 1 516 to maintain the pressure balance between the two cylindrical airbags 512. However, since the two cylindrical airbags 512 are connected through the connecting tube 1 516, the diameter of the connecting tube 1 516 is limited, and the gas flow rate thereof is limited. Therefore, it takes a certain amount of time for the pressure of the two cylindrical airbags 512 to balance. This causes the mutually squeezed portion between the two cylindrical airbags 512 to become an arc surface instead of a flat surface. This causes the mirror aluminum 2 to be pressed into an arc surface, but the curvature of the arc surface is relatively large. When the mirror aluminum 2 is rolled up, it can naturally correct the arc shape. That is, after the two cylindrical airbags 512 have a certain degree of arc surface, it does not affect the final product quality of the mirror aluminum 2.

[0043] There is a clear difference between the cylindrical airbags 512 pressing the mirror aluminum 2 into an arc surface and the linear extrusion range causing deformation of the mirror aluminum surface. The linear extrusion range causes the mirror aluminum 2 to deform, resulting in grooves on the surface of the mirror aluminum 2, making the surface of the mirror aluminum 2 uneven. At this time, the force generated by the rolling of the mirror aluminum 2 cannot restore the surface of the mirror aluminum 2. In the present application, after the two cylindrical airbags 512 generate a certain degree of arc surface, they will not damage the surface of the mirror aluminum 2. They only make the shape of the mirror aluminum 2 into an arc. Therefore, the arc of the mirror aluminum 2 can be corrected by rolling the mirror aluminum 2.

[0044] After the inflatable roller 51 presses the protective film 3 onto the mirror aluminum 2, when the mirror aluminum 2 leaves the inflatable roller 51, the separation component 52 sprays high-pressure gas to separate the cylindrical airbag 512 and the protective film 3 that are stuck together;

[0045] In actual use, the protective film 3 is adhered to the mirror aluminum 2 after being squeezed by the cylindrical airbag 512. The protective film 3 is usually sticky on one side and not sticky on the other side. It is assumed that the sticky side is side A and the non-sticky side is side B. Since the protective film 3 is rolled together, that is, side A and side B are adhered together, it is inevitable that there will be residual glue on side B, which may easily cause the cylindrical airbag 512 that squeezes side B to adhere to the protective film 3. When the mirror aluminum 2 leaves the inflatable roller 51, the cylindrical airbag 512 may easily pull the protective film 3, causing the protective film 3 to deform or generate bubbles, affecting the coating quality. Therefore, when the mirror aluminum 2 leaves the inflatable roller 51, the separation component 52 sprays high-pressure gas to separate the cylindrical airbag 512 and the protective film 3, so as to avoid the cylindrical airbag 512 from pulling the protective film 3, thereby avoiding the problem of affecting the coating quality due to pulling.

[0046] As a further illustration of this application:

[0047] The separation assembly 52 includes an outlet pipe 521 fixedly connected to the frame 1, an outlet slot 522 provided on the outlet pipe 521, and a plurality of second connecting pipes 523 provided on the outlet pipe 521. The plurality of second connecting pipes 523 converge and connect to the outlet of the air compressor pump 515. By providing the plurality of second connecting pipes 523 to connect the outlet pipe 521, the compressed gas can be uniformly introduced into the outlet pipe 521 through the second connecting pipes 523, thereby making the pressure of the compressed gas discharged from the outlet slot 522 more uniform.

[0048] After the air compressor 515 is started, compressed gas is passed into the air outlet pipe 521 through the second connecting pipe 523, and then the compressed gas is ejected through the air outlet groove 522, that is, the compressed gas is used to separate the cylindrical airbag 512 and the protective film 3. The air outlet groove 522 is linear, so that the compressed gas ejected from the air outlet groove 522 can better act on the contact point between the cylindrical airbag 512 and the protective film 3, thereby facilitating the separation of the cylindrical airbag 512 and the protective film 3.

[0049] There is a certain angle between the compressed gas ejected from the gas outlet slot 522 and the mirror aluminum 2, so that the compressed gas can exert a certain pressure on the protective film 3, making it easier to press the protective film 3 more tightly against the mirror aluminum 2 through the compressed gas.

[0050] As a further illustration of this application:

[0051] In the present application, the inflation of the cylindrical airbag 512 and the ejection of the air outlet groove 522 share a common air compression pump 515, which can reduce the number of air compression pumps 515 and facilitate subsequent inspection and maintenance;

[0052] At the same time, in the present application, a pressure-stabilizing valve is provided to control the air compression pump 515 to inflate the cylindrical airbag 512, and the inflation of the cylindrical airbag 512 and the jetting of the air outlet slot 522 share the same air compression pump 515, which has certain advantages. Specifically, since the jetting of the air outlet slot 522 needs to be continuous, the air compression pump 515 is in a continuous operation state. When the internal pressure of the cylindrical airbag 512 is lower than the requirement, the pressure reducing valve is opened. Since the air compression pump 515 is in a continuous operation state, the compressed gas can enter the interior of the cylindrical airbag 512 through the pressure reducing valve, and the inflation can be quickly responded to, thereby ensuring the internal pressure of the cylindrical airbag 512 is stable.

[0053] If an air compression pump 515 is used for the inflation of the cylindrical airbag 512 and the ejection of the air outlet groove 522 respectively, when the pressure of the cylindrical airbag 512 meets the requirements, the air compression pump 515 used for inflating the cylindrical airbag 512 is in a closed state. When the internal pressure of the cylindrical airbag 512 is lower than the requirements, the pressure reducing valve is opened. At this time, a controller is required to control the start of the air compression pump 515. After the air compression pump 515 is started, it takes a certain amount of time to compress the gas so that the gas pressure is increased. Only then can the cylindrical airbag 512 be inflated. This takes a certain amount of time, which is not conducive to the stability of the internal pressure of the cylindrical airbag 512.

[0054] As a further illustration of this application:

[0055] The frame 1 is provided with a driving assembly 6 for driving the pneumatic roller 51 to rotate;

[0056] The driving assembly 6 includes two gears 61 respectively fixedly connected to the two hollow rollers 511 and meshing with each other, and a motor 1 62 mounted on the frame 1 for driving one of the hollow rollers 511 to rotate. The hollow roller 511 is in driving connection with the output shaft of the motor 1 62.

[0057] In actual use, after the motor 1 62 is started, it drives one of the hollow rollers 511 to rotate, and then drives the other hollow roller 511 to rotate through the two meshing gears 61, so that the inflatable roller 51 can rotate;

[0058] In this application, two meshing gears 61 are used to connect the two hollow rollers 511, and the two gears 61 have the same diameter, so that the two hollow rollers 511 rotate at the same speed and in opposite directions, thereby achieving clamping and conveying of the mirror aluminum 2.

[0059] As a further illustration of this application:

[0060] The frame 1 is provided with a discharge rack 7 for discharging the protective film 3;

[0061] The unwinding rack 7 includes a frame 71 provided on the frame 1 for placing the film roll, and a second motor 72 installed on the frame 71 for driving the film roll to rotate. The protective film 3 is wound to form a film roll, and a roller is provided at the center of the film roll. When in use, the roller is installed on the frame 71. After the second motor 72 is started, the roller is driven to rotate, thereby achieving the purpose of unwinding the protective film 3.

[0062] A tensioning roller can be provided on the unloading rack 7 to tension the protective film 3 so that the protective film 3 can be attached to the mirror aluminum 2 later.

[0063] The roller is mounted on the frame 71. Specifically, a rotating block is mounted on the frame 71. The roller is clamped inside the rotating block. The rotating block is connected to the output shaft of the second motor 72. When the second motor 72 is started, the rotating block is driven to rotate.

[0064] like Figure 6-7 As shown, one end of the roller is square. Insert the square end of the roller into the rotating block, and the roller can be driven to rotate by rotating the rotating block.

[0065] As a further illustration of this application:

[0066] The frame 1 is provided with an identification module 8 for identifying whether the mirror aluminum 2 and the protective film 3 are misaligned. The identification module 8 identifies the mirror aluminum 2 with the protective film 3 attached thereto and determines whether the mirror aluminum 2 is misaligned based on whether the protective film 3 extends beyond the side of the mirror aluminum 2.

[0067] The recognition module 8 can adopt a photoelectric sensor, a machine vision sensor, a laser sensor, etc.;

[0068] When using a photoelectric sensor, it detects the position or state of an object by emitting light and receiving reflected or transmitted light. During the film application process, photoelectric sensors can be placed on both sides of the mirrored aluminum 2. If the protective film 3 is misaligned, the protective film 3 will extend from the side of the mirrored aluminum 2. The extended protective film 3 will change the path or intensity of the light, which can be detected by the sensor.

[0069] When using a machine vision sensor, it uses a camera to capture images and uses image processing algorithms to identify and analyze the information in the images. During the film application process, the machine vision sensor can capture images of the protective film 3 and the mirrored aluminum 2, and then compare the feature points or edges in the images to determine whether the protective film 3 is misaligned.

[0070] When using a laser sensor, the laser sensor measures distance and position by emitting a laser beam and receiving the reflected laser. During the film lamination process, a laser sensor can be set on the side of the mirror aluminum 2 to determine whether misalignment occurs by measuring the change in the distance between the protective film 3 and the mirror aluminum 2.

[0071] As a further illustration of this application:

[0072] The frame 1 is provided with an adjusting component 9 for adjusting the position of the protective film 3 according to the information of the recognition module 8; the adjusting component 9 adjusts the position of the protective film 3 by changing the position of the discharge rack 7; when the recognition module 8 uses the machine vision sensor for misalignment detection, when the protective film 3 is misaligned, the machine vision sensor can calculate the misalignment range of the protective film 3, and thus adjust the position of the discharge rack 7 through the adjusting component 9, that is, the purpose of adjusting the position of the protective film 3 is achieved, and automatic adjustment of the protective film 3 and the mirror aluminum 2 after misalignment is achieved.

[0073] As a further illustration of this application:

[0074] The adjustment assembly 9 includes a guide rail 91 provided on the frame 1, a screw rod 92 rotatably provided inside the guide rail 91, a motor 93 installed at the end of the guide rail 91 for driving the screw rod 92 to rotate, and a slider 94 threadedly connected to the outside of the screw rod 92 and sliding inside the guide rail 91; the slider 94 is fixedly connected to the bottom of the frame 71;

[0075] In actual use, the controller receives information from the identification module 8 and controls the motor 3 93 to rotate forward and reverse, thereby driving the screw 92 to rotate, which can drive the slider 94 to slide on the guide rail 91, that is, adjust the position of the frame 71;

[0076] When laminating the mirror aluminum 2, the mirror aluminum 2 is first guided so that the mirror aluminum 2 enters the frame 1 through the center position. Since the width of the mirror aluminum 2 is consistent with the width of the protective film 3, when the position of the protective film 3 is offset, the mirror aluminum 2 and the protective film 3 will be misaligned.

[0077] The main reason for the position offset of the protective film 3 is that the relative position of the film roll and the roller is not fixed. This is because when the protective film 3 is rolled up to form a film roll, there is no strict requirement for the position of the protective film 3 on the roller. It is only necessary to ensure that the protective film 3 is rolled up within a certain range on the roller. Therefore, the relative positions of different film rolls and the roller will be different. Therefore, the protective film 3 released by the frame 71 through different film rolls will have a position offset; therefore, it is necessary to adjust the position of the frame 71 through the adjustment component 9, the purpose of which is to adjust the position of the released protective film 3.
