Description

Technical Field

[0001] The present invention relates to the technical field of production of products to be coated, in particular to a coating process and a coating device. Background Art

[0002] During the LCD screen production process, the surface of the product to be coated needs to be laminated to improve its scratch resistance. Avoiding these bubbles in the lamination process has always been a key challenge, as bubbles not only affect the product's appearance but also have a serious negative impact on its display performance.

[0003] The existing laminating device absorbs the film through an adsorption plate, and presses the film above the product to be coated through a roller, and then slides the film on the adsorption plate by rolling the roller until the film is separated from the adsorption plate and attached to the surface of the product to be coated.

[0004] However, the existing laminating device has several problems during use: 1) Due to the gap between the adsorption plate and the roller, bubbles are easily generated when the film is applied, affecting the film application effect; 2) Due to the friction between the film and the adsorption plate during the film application process, the film is easily scratched; 3) Since pressure must be applied to the film when the roller is pressed down, the film is prone to produce obvious pressure lines (also known as bubble lines) after attachment, thereby affecting the display effect of the product to be laminated. Summary of the Invention

[0005] Based on this, it is necessary to provide a laminating process and a laminating device to address the problem that the above-mentioned film is prone to produce bubbles, scratches and pressure lines.

[0006] According to one aspect of the present application, a lamination process is provided, comprising the following steps:

[0007] S1. Use sticky material to stick to the protective film;

[0008] S2. Move the adhesive material so that the protective film is located above the product to be coated;

[0009] S3, using the film laminating assembly to press the viscous material, so that the protective film approaches the product to be coated at an angle downward until the bottom edge of the protective film contacts the surface of the product to be coated;

[0010] S4, moving the film-applying assembly so that the protective film is attached to the surface of the product to be coated, and an inclination angle is generated between the adhesive material and the protective film, and the adhesive material is continued to be moved until it is separated from the protective film, thereby completing the film-applying operation;

[0011] S5. Rewinding the viscous material so that the mucous membrane area of ​​the viscous material is automatically replaced.

[0012] In one embodiment, step S4 specifically includes: reciprocatingly moving the film-applying assembly so that the protective film is completely attached to the surface of the product to be coated.

[0013] The above-mentioned laminating process replaces the absorption of the protective film by the adsorption device by the adhesion of the protective film by the sticky material, and utilizes the softness of the sticky material to prevent the protective film from being scratched due to friction with the sticky material during the laminating process; and when attaching the protective film, the film-attaching component can be directly pressed down on the sticky material, so that the bottom edge of the protective film first contacts the surface of the product to be laminated, and then the film-attaching component can ensure that the protective film and the surface of the product to be laminated are always in line contact during the process of attaching the protective film, effectively solving the bubble problem and ensuring the laminating effect; in addition, since the length of the sticky material is greater than the length of the protective film, when the protective film is laminated, the area where the film-attaching component initially applies pressure may not be in the area where the protective film is located, thereby avoiding the generation of pressure lines and improving the laminating quality.

[0014] According to another aspect of the present application, a laminating device is provided, comprising:

[0015] A carrying mechanism, which is used to support and fix the product to be coated;

[0016] a first film supplying machine, configured to provide a first protective film for the product to be coated on the carrying mechanism;

[0017] A moving mechanism, the moving mechanism having a moving end capable of moving between the first film supply machine and the supporting mechanism;

[0018] The laminating mechanism includes a frame, a material discharging assembly, a material receiving assembly, a film pasting assembly and a driving member. The frame is arranged on the movable end of the movable mechanism. The material discharging assembly, the material receiving assembly and the driving member are all arranged on the frame. The material discharging assembly is used to fix the sticky material. The material receiving assembly is used to roll up the sticky material. The film pasting assembly is located between the material discharging assembly and the material receiving assembly and is transmission-connected to the driving member. The driving member is used to drive the film pasting assembly to move laterally between the material discharging assembly and the material receiving assembly.

[0019] The above-mentioned laminating device can stick to the first protective film on the first film supply machine through the stickiness of the sticky material, and then replace the adsorption plate to absorb the first protective film. Since the sticky material is soft, the first protective film will not be scratched due to friction with the sticky material during the laminating process; and when the sticky material is used instead of the adsorption plate, the laminating component can be directly pressed down on the sticky material, and the first protective film on the sticky material is attached to the product to be laminar during the movement. There is no gap between the laminating component and the sticky material during the laminating process, so the bubble problem can be effectively solved and the laminating effect can be ensured; in addition, since the length of the sticky material between the discharge component and the receiving component is greater than the length of the first protective film, when the first protective film is laminating, the area where the laminating component initially applies pressure may not be in the area where the first protective film is located, thereby avoiding the generation of pressure lines and improving the laminating quality.

[0020] In one embodiment, the material receiving assembly includes a first frame, a first driver and a first fixed shaft, the first driver and the first fixed shaft are both arranged on the first frame, and the first driver is transmission-connected to the first fixed shaft, and the first driver is used to drive the first fixed shaft to rotate.

[0022] In one embodiment, the discharge assembly includes a second frame and a second fixed shaft, the second fixed shaft is rotatably connected to the second frame, and the viscous material is sleeved on the second fixed shaft.

[0023] In the above embodiment, the unused rolled viscous material is fixed by the second fixed shaft, so that when the material receiving assembly is performing a rolling operation on the viscous material, the second fixed shaft can rotate accordingly and assist in outputting the unused rolled viscous material.

[0024] In one embodiment, the laminating mechanism further includes a pressing piece, a fixed surface is provided on the discharge assembly, a second driver is provided on the frame, the pressing piece is transmission-connected to the second driver, the second driver is used to drive the pressing piece to move in a direction close to or away from the fixed surface, and the fixed surface and the pressing piece are respectively used to abut against the opposite sides of the viscous material.

[0025] In the above embodiment, the second driver can drive the pressing piece to move longitudinally in the direction close to the discharge component, compressing and fixing part of the viscous material between the pressing piece and the discharge component, so that when the receiving component rewinds the viscous material, the viscous material will be subjected to tension and straightened accordingly.

[0028] In one embodiment, the film-sticking assembly includes a connecting member and a wheel body, both of which are transmission-connected to a driving member, and there is a gap between the connecting member and the wheel body for the adhesive material to pass through, and the connecting member and the wheel body are respectively in contact with opposite sides of the adhesive material.

[0029] In the above embodiment, the first protective film on the adhesive material can be attached to the product to be coated by the moving wheel body. In addition, since the adhesive material passes through the gap and abuts against the connecting member and the wheel body respectively, during the attachment process, the movement of the connecting member can make the adhesive material leave the attached first protective film in time, thereby completing the film attachment operation.

[0030] In one embodiment, the laminating device further includes a second film supply machine and a flipping mechanism, wherein the flipping mechanism is used to flip the product to be laminated on the carrying mechanism, and the second film supply machine is used to provide a second protective film for the product to be laminated on the carrying mechanism, and the movable end of the movable mechanism can also move between the second film supply machine and the carrying mechanism.

[0069] An embodiment of the present invention provides a laminating device and a laminating process implemented based on the laminating device. The laminating device and the laminating process are used to attach a protective film to the surface of a product during the production process of the product, and solve the problem of bubbles, scratches and pressure lines easily generated by laminating in the prior art.

[0070] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides a laminating device, which is mounted on a supporting surface (such as the ground, a table, or the surface of other supporting bodies) and includes a supporting mechanism 1, a first film supply machine 2, a moving mechanism 3 and a laminating mechanism 4.

[0071] The support mechanism 1 is used to support and secure the product to be laminated, facilitating subsequent laminating operations by the laminating mechanism 4. Specifically, a support platform is provided on the top surface of the support mechanism 1, upon which the product to be laminated can be placed flat. The support mechanism 1 supports and secures the product to be laminated. Furthermore, the product to be laminated has front and back surfaces disposed opposite each other.

[0072] The first film feeder 2 is used to provide a first protective film to the product to be coated on the carrier 1. Specifically, the first protective film is a single sheet of protective film that matches the front shape of the product to be coated. The first film feeder 2 is equipped with multiple sheets of first protective film to continuously supply the product to be coated on the carrier 1.

[0073] The moving mechanism 3 has a moving end configured to move between the first film feeder 2 and the carrier mechanism 1. Specifically, the moving end of the moving mechanism 3 is connected to the laminating mechanism 4. The moving mechanism 3 is used to drive the laminating mechanism 4 to move between the first film feeder 2 and the carrier mechanism 1, so that the laminating mechanism 4 can obtain the first protective film from the first film feeder 2 and attach the first protective film to the product to be laminated on the carrier mechanism 1.

[0074] The laminating mechanism 4 includes a frame 41, a feeding assembly 42, a receiving assembly 43, a film laminating assembly 44 and a driving member 45. The frame 41 is arranged on the moving end of the moving mechanism 3. The feeding assembly 42, the receiving assembly 43 and the driving member 45 are all arranged on the frame 41. The feeding assembly 42 is provided with a rolled sticky material 5, and part of the sticky material 5 is fixed on the receiving assembly 43. The receiving assembly 43 is used to roll up the sticky material 5. The driving member 45 is connected to the film laminating assembly 44 for driving the film laminating assembly 44 to move laterally between the feeding assembly 42 and the receiving assembly 43.

[0075] Specifically, the unwinding assembly 42 and the receiving assembly 43 are both disposed on the bottom surface of the frame 41. A rolled viscous material 5 is sleeved on the unwinding assembly 42, while a portion of the viscous material 5 is secured to the receiving assembly 43. Specifically, a portion of the viscous material 5 is rolled and sleeved on the unwinding assembly 42, a portion is unrolled and positioned between the unwinding and receiving assemblies 42 and 43, and the remaining portion is secured to the receiving assembly 43. The receiving assembly 43 rewinds the secured viscous material 5, thereby discharging the viscous material 5 from the unwinding assembly 42.

[0076] The film applying assembly 44 is positioned between the frame 41 and the unfolded adhesive material 5, with the bottom of the film applying assembly 44 abutting the non-adhesive surface of the adhesive material 5. A driving member 45 is in driving connection with the film applying assembly 44. The driving member 45 can drive the film applying assembly 44 to move laterally on the non-adhesive surface of the adhesive material 5.

[0077] More specifically, the driver 45 is mounted on the fixed top surface of the frame 41. The frame 41 has a through-hole, through which the top of the film application assembly 44 passes and connects to the drive shaft of the driver 45. By placing the driver 45 on the top surface of the frame 41, the positions of the various components on the frame 41 are more rationally distributed, ensuring that the driver 45 does not interfere with the retraction and deployment of the viscous material 5 or the film application operation of the film application assembly 44. It is understood that in this application, the driver 45 can be implemented as a linear motor, electric cylinder, or pneumatic cylinder. The viscous material 5 is a viscous transfer film.

[0078] Existing laminating devices mostly use a flat plate with adsorption holes as an adsorption plate, which uses suction to make the adsorption plate obtain the protective film, and uses a roller to press the protective film onto the product to be coated. The roller rolls to make the protective film slide on the adsorption plate, and finally the protective film is separated from the adsorption plate and attached to the surface of the product to be coated. However, there are several problems with this laminating device during use: 1) Due to the gap between the adsorption plate and the roller, bubbles are easily generated when the film is applied, which affects the film application effect; 2) During the film application process, due to the friction between the film and the adsorption plate, the film is easily scratched (if the adsorption plate is made of a soft material, it may cause wear and affect the production environment, or excessive friction may cause inaccurate film application position and other adverse effects); 3) Since pressure must be applied to the film when the roller is pressed down, the film is prone to produce obvious pressure lines (also known as bubble lines) after attachment, which affects the display effect of the product to be coated.

[0079] The laminating device of the present application uses a soft adhesive film 5 instead of an adsorption plate for the mold-taking operation, thereby improving the protection effect of the first protective film and preventing the first protective film from being scratched due to friction with the adhesive film 5 during the laminating process; and when the adhesive film 5 is used instead of the adsorption plate, the roller assembly 44 can be directly pressed down on the adhesive film 5, and the first protective film on the adhesive film 5 is attached to the product to be laminarized during the movement. There is no gap between the roller assembly 44 and the adhesive film 5 during the attachment process, thereby effectively solving the bubble problem and ensuring the laminating effect; in addition, since the length of the adhesive film 5 between the discharge assembly 42 and the receiving assembly 43 can be greater than the length of the first protective film, when the first protective film is laminating, the area where the roller assembly 44 initially applies pressure may not be in the area where the first protective film is located, thereby avoiding the generation of pressure lines and improving the laminating quality.

[0080] During specific operation, the above-mentioned laminating device can cooperate with the discharge component 42 and the receiving component 43 to make the laminating mechanism 4 have an un-adhered adhesive material 5, and then move the laminating mechanism 4 to the first film supply machine 2 through the moving mechanism 3, so that the laminating mechanism 4 sticks the first protective film on the first film supply machine 2 through the adhesive material 5, and then move the laminating mechanism 4 to the supporting mechanism 1 through the moving mechanism 3, and make one end of the first protective film contact with the product to be coated, and then drive the film sticking component 44 to move on the top surface of the adhesive material 5 through the driving member 45, so that the first protective film contacts the product to be coated under appropriate pressure and completes the laminating process.

[0081] In one embodiment, the material receiving assembly 43 includes a first frame 431, a first driver 432 and a first fixed shaft 433. The first driver 432 and the first fixed shaft 433 are both arranged on the first frame 431, and the first driver 432 is transmission-connected to the first fixed shaft 433. The first driver 432 is used to drive the first fixed shaft 433 to rotate.

[0082] Specifically, a first frame 431 is disposed on the bottom surface of the frame 41. A first fixed shaft 433 is rotatably disposed within the first frame 431, and a portion of the viscous material 5 is fixed to the first fixed shaft 433. The drive shaft of the first driver 432 is connected to the first fixed shaft 433. When the first driver 432 drives the first fixed shaft 433 to rotate, the viscous material 5 is wound around the first fixed shaft 433, thereby performing a reeling operation on the viscous material 5. It will be appreciated that in the present application, a servo motor can be used as the first driver 432.

[0083] The laminating device fixes one end of the viscous material 5 on the first fixed shaft 433 , so that the first driver 432 can drive the first fixed shaft 433 to rotate, thereby performing a winding operation on the viscous material 5 .

[0084] In one embodiment, the unloading assembly 42 includes a second frame 421 and a second fixed shaft 422 . The second fixed shaft 422 is rotatably connected to the second frame 421 , and the rolled viscous material 5 is sleeved on the second fixed shaft 422 .

[0085] Specifically, the second frame 421 is disposed on the bottom surface of the frame 41, and the second fixed shaft 422 is rotatably disposed within the second frame 421. The rolled viscous material 5 is sleeved on the second fixed shaft 422. The unused rolled viscous material 5 is secured by the second fixed shaft 422, so that when the receiving assembly 43 is rewinding the viscous material 5, the second fixed shaft 422 can rotate accordingly and assist in the discharge of the unused rolled viscous material 5.

[0086] In addition, there is a gap between the second frame 421 and the frame 41 , and the end of the viscous material 5 can pass through the gap from the second frame 421 and be fixed on the material receiving assembly 43 .

[0087] In one embodiment, the laminating mechanism 4 further includes a pressing piece 46, a fixed surface is provided on the discharge assembly 42, a second driver is provided on the frame 41, the pressing piece 46 is transmission-connected to the second driver, and the second driver is used to drive the pressing piece 46 to move in a direction close to or away from the fixed surface, and the fixed surface and the pressing piece 46 are respectively used to abut against the opposite sides of the adhesive material 5.

[0088] Specifically, a second driver is provided on the bottom surface of the frame 41, and a pressure piece 46 is connected to the drive shaft of the second driver. The fixed surface is the top surface of the unwinding assembly 42. The second driver drives the pressure piece 46 to move toward the top surface of the unwinding assembly 42, compressing and securing a portion of the viscous material 5 between the pressure piece 46 and the unwinding assembly 42. This allows the viscous material 5 to be tensioned and straightened when the rewinding assembly 43 rewinds it. This straightened viscous material 5 effectively improves adhesion to the first protective film.

[0089] More specifically, the pressing member 46 is located inside the gap between the second frame 421 and the frame 41. The second actuator can drive the pressing member 46 to move longitudinally within the gap to compress and secure the viscous material 5 in the gap. It is understood that in the present application, the second actuator can be a linear motor, an electric cylinder, or a pneumatic cylinder.

[0090] In one embodiment, the laminating mechanism 4 also includes a tensioning member 47, a third drive is provided on the frame 41, the tensioning member 47 is transmission-connected to the third drive, the tensioning member 47 is located between the discharge assembly 42 and the receiving assembly 43, and the third drive is used to drive the tensioning member 47 to rise and fall relative to the viscous material 5.

[0091] Specifically, a third driver is provided on the bottom surface of the frame 41, and a tensioning member 47 is connected to the drive shaft of the third driver. The third driver drives the tensioning member 47 to move longitudinally away from the frame 41, allowing the tensioning member 47 to abut against the straightened viscous material 5 and apply corresponding pressure to the straightened viscous material 5, thereby tensioning the viscous material 5 and achieving better adhesion to the first protective film. It is understood that in this application, the third driver can be a linear motor, an electric cylinder, or a pneumatic cylinder.

[0092] In addition, the tensioning member 47 is a round shaft. Compared with other shapes such as square ones, the shaft-shaped tensioning member 47 is less likely to damage the viscous material 5 when it contacts the viscous material 5 .

[0093] In one embodiment, the film-sticking assembly 44 includes a connecting member 442 and a wheel body 443, both of which are transmission-connected to the driving member 45, and there is a gap between the connecting member 442 and the wheel body 443 for the adhesive material 5 to pass through, and the connecting member 442 and the wheel body 443 respectively abut against the opposite sides of the adhesive material 5.

[0094] Specifically, the connector 442 and the wheel 443 are both mounted on the third bracket 441. The top of the third bracket 441 extends through a through hole and connects to the driver 45. The connector 442 and the wheel 443 are both mounted within the third bracket 441, with a gap between the connector 442 and the wheel 443 for the viscous material 5 to pass through. The viscous material 5 discharged by the discharge assembly 42 first abuts against the top surface of the connector 442, then passes through the gap and abuts against the bottom surface of the wheel 443, and finally is secured to the receiving assembly 43.

[0095] The above-mentioned laminating device can attach the first protective film on the adhesive material 5 to the product to be coated through the moving wheel body 443. In addition, since the adhesive material 5 passes through the gap and abuts against the connecting member 442 and the wheel body 443 respectively, during the attachment process, the movement of the connecting member 442 can make the adhesive material 5 leave the attached first protective film in time, thereby completing the laminating operation.

[0096] In one embodiment, the laminating device also includes a second film supply machine 6 and a flipping mechanism 7. The flipping mechanism 7 is used to flip the product to be coated on the supporting mechanism 1. The second film supply machine 6 is used to provide the product to be coated on the supporting mechanism 1 with a second protective film that matches the shape of the back of the product to be coated. The moving mechanism 3 is also used to drive the mobile end to move between the second film supply machine 6 and the supporting mechanism 1.

[0097] Specifically, the flipping mechanism 7 includes a moving portion, a flipping portion, and a fixed portion. The fixed portion is fixed to the moving portion via the flipping portion. The moving portion drives the fixed portion toward the support mechanism 1, allowing the fixed portion to secure the product to be coated. Once secured, the product to be coated can be driven by the moving portion to move away from the support mechanism 1, allowing the flipping portion to flip the fixed portion and the product to be coated. After flipping, the product to be coated can be placed back on the support mechanism 1 under the drive of the moving portion, allowing the laminating mechanism 4 to laminarize the other side.

[0098] The first protective film is a single protective film that matches the front of the product to be coated, and the second protective film is a single protective film that matches the back of the product to be coated. The second film supply machine 6 is provided with multiple second protective films so that it can continuously provide the second protective film for the product to be coated on the carrier mechanism 1.

[0099] The moving end of the moving mechanism 3 is connected to the laminating mechanism 4, and the moving mechanism 3 is also used to drive the laminating mechanism 4 to move between the second film supply machine 6 and the carrying mechanism 1, so that the laminating mechanism 4 can obtain the second protective film from the second film supply machine 6 and attach the second protective film to the product to be laminarized on the carrying mechanism 1.

[0100] The above-mentioned laminating device can flip the product to be laminated on the supporting mechanism 1 through the flipping mechanism 7, and stick the second protective film on the second film supply machine 6 through the laminating mechanism 4 to perform the laminating operation on the other side of the product to be laminated, so that the laminating device of the present application can complete the laminating operation on both sides of the product to be laminated.

[0101] In one embodiment, the laminating device further includes a visual detection mechanism 8, which is signal-connected to the carrying mechanism 1 and the laminating mechanism 4. The visual detection mechanism 8 is used to capture an image of the product to be laminated located on the carrying mechanism 1, so as to adjust the angle of the carrying mechanism 1 and the stop position of the laminating assembly 44 according to the image.

[0102] Specifically, the visual inspection mechanism 8 is connected to the carrying mechanism 1 and the laminating mechanism 4 through the controller. The visual inspection mechanism 8 is used to collect images of the product to be laminated located on the carrying mechanism 1 so that the controller can adjust the angle of the carrying mechanism 1 and the stop position of the laminating assembly 44 according to the image.

[0103] The above-mentioned laminating device can timely grasp the situation of the product to be laminated through the visual detection mechanism 8, so that the controller can adjust the angle of the supporting mechanism 1 and control the stop position of the film-laminating component 44 according to the corresponding situation. By adjusting the angle of the supporting mechanism 1, the product to be laminated can be kept horizontal, and by controlling the stop position of the film-laminating component 44, the film-laminating component 44 can complete the laminating operation to ensure the laminating effect.

[0104] In one embodiment, the carrying mechanism 1 includes a moving module 11 and a carrying platform 12 . The carrying platform 12 is disposed on the moving module 11 , and the moving module 11 is used to drive the carrying platform 12 to move.

[0105] Specifically, the carrying platform 12 is used to support and fix the product to be coated. After the film application operation is completed on the product to be coated at the coating station, the moving module 11 can drive the carrying platform 12 to move to the unloading station to remove the product to be coated.

[0106] In one embodiment, the moving mechanism 3 includes an X-axis module 31, a Y-axis module 32 and a Z-axis module 33. The X-axis module 31 is connected to the Y-axis module 32 for driving the Y-axis module 32 to move laterally along the X-axis direction. The Y-axis module 32 is connected to the Z-axis module 33 for driving the Z-axis module 33 to move laterally along the Y-axis direction. The Z-axis module 33 is connected to the coating mechanism 4 for driving the coating mechanism 4 to move longitudinally along the Z-axis direction.

[0107] Specifically, the X-axis module 31 is mounted on the support surface, the Y-axis module 32 is mounted on the movable portion of the X-axis module 31, the Z-axis module 33 is mounted on the movable portion of the Y-axis module 32, and the laminating mechanism 4 is mounted on the movable portion of the Z-axis module 33. The X-axis module 31, the Y-axis module 32, and the Z-axis module 33 enable the laminating mechanism 4 to move in the X, Y, and Z directions, allowing for flexible adjustment of its position.

[0108] The embodiments of the present application further provide a laminating process, which can be applied to the above-mentioned laminating device, and includes the following steps:

[0109] S1. Using adhesive material to stick to the protective film. Specifically, in this step, the laminating mechanism 4 fixes the adhesive material 5, and the moving mechanism 3 moves the laminating mechanism 4, thereby moving the adhesive material 5 so that the adhesive material 5 can stick to the protective film.

[0110] S2. Move the viscous material 5 so that the protective film is located above the product to be coated. Specifically, in this step, the moving mechanism 3 is used again to move the coating mechanism 4 to drive the viscous material 5 to move above the product to be coated.

[0111] S3. Use the film-applying assembly to compress the viscous material, causing the protective film to approach the product to be coated at an angle and downward, until the bottom edge of the protective film contacts the surface of the product to be coated. Specifically, in this step, the film-applying assembly is driven to move longitudinally toward the viscous material 5. Under the pressure of the film-applying assembly, the viscous material 5 is moved toward the product to be coated at an angle and downward, thereby driving the protective film toward the product to be coated at an angle and downward, until the bottom edge of the protective film contacts the surface of the product to be coated.

[0112] S4. Move the film-applying assembly so that the protective film adheres to the surface of the product to be coated, creating an inclination angle between the adhesive material and the protective film. Continue to move the adhesive material until it detaches from the protective film, completing the film-applying operation. Specifically, in this step, the wheel 443 of the film-applying assembly is driven to move horizontally, attaching the protective film on the adhesive material 5 to the product to be coated. During the attachment process, since the adhesive material 5 passes through the gap and abuts against the connector 442 and wheel 443 respectively, the movement of the connector 442 allows the adhesive material 5 to be promptly removed from the attached protective film, thereby completing the film-applying and adhesive material removal operations.

[0113] In addition, in this step, the wheel body 443 of the film-sticking assembly can also be driven to move horizontally, so that the protective film on the adhesive material 5 is attached to the product to be coated, and then the film-sticking assembly is driven to rotate so that the adhesive material 5 is promptly separated from the attached protective film, thereby completing the operation of film-sticking and adhesive material separation.

[0114] S5, reeling up the viscous material so that the mucous membrane area of ​​the viscous material is automatically replaced. Specifically, in this step, the material receiving assembly 43 is driven to reel up the viscous material 5 so that the mucous membrane area of ​​the viscous material is automatically replaced.

[0115] In one embodiment, step S4 includes:

[0116] S41, reciprocatingly moving the film-applying assembly so that the protective film is completely attached to the surface of the product to be coated. Specifically, in this step, the driving member 45 drives the film-applying assembly 44 to move back and forth laterally so that the protective film is completely attached to the surface of the product to be coated.

[0117] S42: Move the adhesive material away from the protective film to complete the laminating operation. Specifically, in this step, the laminating mechanism 4 is moved by the moving mechanism 3, thereby moving the adhesive material 5, so that the adhesive material 5 leaves the protective film and is attached to another protective film to perform the laminating operation on the next product.

[0118] When the laminating device of the present application uses the above-mentioned laminating process to perform the laminating operation, the protective film is adhered to the protective film by the sticky material instead of being absorbed by the adsorption device, and the softness of the sticky material is used to prevent the protective film from being scratched due to friction with the sticky material during the laminating process; and when the protective film is attached, the film-attaching component can be directly pressed down on the sticky material, so that the bottom edge of the protective film first contacts the surface of the product to be coated, and then the film-attaching component can ensure that the protective film and the surface of the product to be coated are always in line contact during the process of attaching the protective film, effectively solving the bubble problem and ensuring the laminating effect; in addition, since the length of the sticky material is greater than the length of the protective film, when the protective film is attached, the area where the film-attaching component initially applies pressure may not be in the area where the protective film is located, thereby avoiding the generation of pressure lines and improving the laminating quality.

[0119] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0120] The above embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
