[0034] In the related art, product processing is usually completed manually, especially for products with complex surface structures to be film-coated. For example, for shell products, both the top and side surfaces need to be film-coated. Workers need to work carefully to attach the protective film to each surface. The workers' work intensity is high, and the quality of the film is difficult to control. The labor cost is high and the film-coating efficiency is low.

[0035] Based on this, reference Figures 1 to 5 The embodiment of the present invention provides a multi-sided film-sticking device, which replaces manual labor to perform film-sticking processing on various surfaces of the product to be coated by mechanical means, and can stick films on curved surfaces with good film-sticking effects.

[0036] refer to Figures 1 to 3, a multi-sided film laminating device according to an embodiment of the present invention includes a processing table assembly 100, a film covering assembly 200, a longitudinal pressing laminating assembly 300 and a side pressing laminating assembly 400; the processing table assembly 100 includes a rotating table 110 and a plurality of product clamping structures 120, along the rotation direction of the rotating table 110 are sequentially provided with loading and unloading stations, film covering stations, longitudinal pressing stations and side pressing stations, the product clamping structure 120 is connected to the rotating table 110, the rotating table 110 is used to drive the product clamping structure 120 to the corresponding station, the loading and unloading stations are used to cooperate with external loading and unloading devices to realize corresponding loading and unloading actions, and the product loading The clamping structure 120 includes a product fixture 130 and a film supporting column 140. The product fixture 130 is installed on the rotating table 110. The product fixture 130 is used to clamp the product to be film-coated. The top of the film supporting column 140 is provided with a film supporting member 141 for supporting the protective film. The film supporting member 141 is located on one side of the product fixture 130. The film supporting column 140 can be lifted and moved and is connected to the rotating table 110; the film covering assembly 200 is provided at the film covering station. The film covering assembly 200 includes a film covering translation mechanism 210 and a film covering pressure roller 220. The film covering pressure roller 220 is rotatably connected to the film covering translation mechanism 210. The film covering translation mechanism 210 is used to drive the film covering. The dynamic cover film pressing roller 220 moves in translation to press the protective film tightly against the top surface of the product to be covered at the cover film station; the longitudinal pressing laminating assembly 300 is arranged at the longitudinal pressing station, and the longitudinal pressing laminating assembly 300 includes a longitudinal pressing lifting mechanism 310 and a longitudinal pressing roller 320, the longitudinal pressing roller 320 is located above the film supporting member 141 at the longitudinal pressing station, and the longitudinal pressing roller 320 is rotatably connected to the longitudinal pressing lifting mechanism 310, and the longitudinal pressing lifting mechanism 310 is used to drive the longitudinal pressing roller 320 to rise and fall, so as to achieve the protection film being attached to the side of the product to be covered at the longitudinal pressing station, and when the longitudinal pressing roller 320 descends, it can push the film supporting member 141 to descend and make way; the side pressing laminating assembly Component 400 is arranged at the side pressing station, and the side pressing laminating component 400 includes a side pressing lifting mechanism 410, a side pressing rotating mechanism 420 and a side pressing roller 430. The side pressing rotating mechanism 420 is connected to the side pressing lifting mechanism 410, and the side pressing lifting mechanism 410 is used to drive the side pressing rotating mechanism 420 to lift and lower, and the side pressing roller 430 is rotatably connected to the side pressing rotating mechanism 420. The side pressing rotating mechanism 420 is used to drive the side pressing roller 430 to rotate around the product fixture 130 at the side pressing station to achieve the bonding of the protective film to the circumferential curved surface of the product to be laminated at the side pressing station, and the circumferential curved surface of the product to be laminated is connected between two adjacent side surfaces.

[0037] Through the cooperation between the various mechanical components, the protective film can be unfolded on the product to be laminated and reliable lamination processing can be achieved with high lamination efficiency. The edge of the protective film is attached to the film supporting member 141 and unfolded. After the cover film component 200 laminates the protective film to the top surface of the product to be laminated by rolling, the longitudinal pressing laminating component 300 laminates the protective film to the side of the product to be laminated by rolling. The side pressure lifting mechanism 410 indirectly drives the side pressure roller 430 to descend to the side of the product to be laminated at the side pressure station. The side pressure rotates The mechanism 420 drives the side pressure roller 430 to rotate around the product to be filmed, that is, the side pressure roller 430 rotates with the axis of the product to be filmed as the center, and the side pressure roller 430 rolls the protective film to the circumferential curved surface of the product to be filmed in a rotating manner. For the product to be filmed with a circumferential curved surface, the top surface and side surface of the product to be filmed are first laminated to obtain a stable film laminating foundation, and then the circumferential curved surface of the product to be filmed is laminated, which can effectively ensure the laminating effect and avoid defects such as bubbles and wrinkles in the film.

[0038] Understandably, the reference Figure 1 The rotating table 110 includes a rotating drive mechanism 111 and a turntable 112. The turntable 112 is connected to the rotating drive mechanism 111. The rotating drive mechanism 111 can drive the turntable 112 to rotate. The turntable 112 is used to install various product clamping structures 120. The various product clamping structures 120 are evenly distributed along the circumference of the turntable 112. The rotating drive mechanism 111 can be a rotary motor.

[0039] It is understood that the film support member 141 is a Teflon support block. Teflon, also known as polytetrafluoroethylene (PTFE), has an extremely low coefficient of friction and excellent anti-adhesion properties. This ensures that the protective film can be smoothly separated from the Teflon support block during lamination, thereby effectively improving the reliability of the film support structure.

[0040] Understandably, the reference Figure 2The longitudinal pressure laminating component 300 also includes a longitudinal pressure lifting member 330, a longitudinal pressure elastic member 340 and a swing arm 350. The longitudinal pressure lifting member 330 is connected to the mover of the longitudinal pressure lifting mechanism 310, and the longitudinal pressure roller 320 is rotatably connected to the swing arm 350. The vertical projection of the longitudinal pressure roller 320 partially overlaps with the vertical projection of the product fixture 130 to ensure that the longitudinal pressure roller 320 can form a reliable rolling laminating effect on the product to be laminarized. The swing arm 350 is rotatably connected to the longitudinal pressure lifting member 330, and the two ends of the longitudinal pressure elastic member 340 are respectively connected to the longitudinal pressure lifting member 330 and the swing arm 350, so that the longitudinal pressure roller 320 forms a tendency to move close to the axis of the product fixture 130. The longitudinal pressure driving component is driven As the dynamic longitudinal pressure lifter 330 descends, the longitudinal pressure roller 320 presses against the product to be laminated at the longitudinal pressing station. The product to be laminated is mounted on the product fixture 130 at the longitudinal pressing station. Guided by the surface structure of the product to be laminated, and due to the elastic rotational connection between the swing arm 350 and the longitudinal pressure lifter 330, the longitudinal pressure roller 320 deviates from its original trajectory during descent and moves to the side of the product fixture 130. The swing arm 350 rotates, and the elastic restoring force of the longitudinal pressure elastic member 340 causes the longitudinal pressure roller 320 to float. The longitudinal pressure roller 320 can achieve contoured movement according to the side of the product to be laminated, effectively improving the lamination effect of the longitudinal pressure laminating assembly 300 on the product to be laminated. The longitudinal pressure elastic member 340 can be a compression spring.

[0041] Specifically, the longitudinal pressure lifting mechanism 310 is configured as a linear module or cylinder that can be driven to achieve lifting and lowering. The mover of the longitudinal pressure lifting mechanism 310 is fixedly connected to the longitudinal pressure lifting member 330. A swing arm 350 is provided on the opposite sides of the longitudinal pressure lifting member 330. The middle part of the swing arm 350 is rotatably connected to the longitudinal pressure lifting member 330. The bottom of each swing arm 350 is rotatably connected to the longitudinal pressure roller 320. The rotating shaft of the longitudinal pressure roller 320 is horizontally arranged. The two ends of the longitudinal pressure elastic member 340 are respectively connected to the top of the swing arm 350 and the longitudinal pressure lifting member 330, so that the two longitudinal pressure rollers 320 can form a movement effect that can float according to the product to be filmed.

[0042] Understandably, the reference Figure 2The longitudinal pressure laminating component 300 further includes a pushing member 360, which is connected to the longitudinal pressure lifting member 330. The product clamping structure 120 further includes a trigger column 150, a linkage member 160 and a self-locking mechanism 170. The film supporting column 140 and the trigger column 150 are both connected to the linkage member 160. The self-locking mechanism 170 is connected to the rotating table. The self-locking mechanism 170 is used to self-lock the linkage member 160 to achieve locking of the top surface of the film supporting member 141 and the top surface of the product fixture 130. A height, thereby ensuring that the relative position between the supporting module and the product fixture 130 is stable and reliable, which can improve the film supporting effect. The pushing member 360 is located above the trigger column 150. Under the driving action of the longitudinal pressure lifting mechanism 310, the pushing member 360 follows the longitudinal pressure lifting member 330 to descend, and the pushing member 360 presses the trigger column 150 down, thereby indirectly driving the film supporting member 141 to descend to make way for the longitudinal pressure roller 320, which can effectively improve the reliability of the operation of the entire film laminating device.

[0043] Understandably, the reference Figure 1 、 Figure 2 The rotating platform 110 is provided with a first guide hole 113 and a second guide hole 114. The trigger column 150 is disposed through the first guide hole 113, and the film support column 140 is disposed through the second guide hole 114. When the rotating platform 110 is configured to include a rotation drive mechanism 111 and a turntable 112, the first guide hole 113 and the second guide hole 114 are disposed on the turntable 112. Optionally, a trigger block is provided on the top of the trigger column 150. The horizontal projection area of the trigger block is larger than the opening area of the first guide hole 113. This prevents the trigger column 150 from completely disengaging from the first guide hole 113 and improves the error tolerance when the push member 360 pushes the trigger block to move, thereby effectively improving the reliability of each action.

[0044] Understandably, the reference Figure 2 The self-locking mechanism 170 includes two clamping springs 171 and two clamping members 172. The two clamping members 172 are located on opposite sides of the linkage member 160. One end of the clamping spring 171 is connected to the clamping member 172, so that the two clamping members 172 tend to move toward each other, thereby clamping the linkage member 160 and achieving a self-locking position for the film support member 141. The self-locking mechanism 170 also includes a self-locking guide rail 173. The self-locking guide rail 173 is connected to the rotating table 110. The clamping member 172 is connected to the self-locking guide rail 173. The clamping member 172 can slide along the self-locking guide rail 173. The self-locking guide rail 173 can effectively limit the movement trajectory of the clamping member 172, thereby improving the reliability of the clamping action formed by the clamping member 172.

[0045] Specifically, the self-locking mechanism 170 also includes a guide wheel 174, which is rotatably connected to the clamping member 172. The guide wheel 174 is used to clamp the linkage member 160. By setting the guide wheel 174 to replace the sliding friction of the clamping member 172 with rolling friction, the wear on the linkage member 160 can be effectively reduced, thereby effectively extending the service life of the overall structure, and at the same time ensuring the smoothness of the movement of the linkage member 160.

[0046] Understandably, the reference Figure 2 The multi-sided film laminating device also includes a lifting and resetting component 500. The lifting and resetting components 500 are arranged below the longitudinal pressing station and the lateral pressing station. The lifting and resetting components 500 include a lifting drive mechanism 510 and a lifting member 520. The lifting member 520 is connected to the lifting drive mechanism 510. The lifting member 520 is located directly below the linkage member 160 at the longitudinal pressing station. The lifting drive mechanism 510 is used to drive the lifting member 520 to rise, so as to realize the lifting and resetting of the linkage member 160, thereby realizing the rising and resetting of the corresponding film supporting member 141.

[0047] It can be understood that both the longitudinal pressing station and the lateral pressing station are provided with a lifting and resetting assembly 500 , and the lifting driving mechanism 510 can lift and reset the linkage member 160 at the corresponding station by driving the lifting member 520 , thereby resetting the corresponding film supporting member 141 .

[0048] It is understandable that the loading and unloading station is also provided with a jacking and resetting assembly 500. The jacking drive mechanism 510 at this station drives the linkage part 160 of the jacking part 520 to achieve jacking, which can effectively ensure the resetting of the film supporting part 141, thereby ensuring the reliability of the loading and unloading action.

[0049] Understandably, the reference Figure 2 The product clamping structure 120 also includes a push spring 180, one end of which is connected to the linkage 160, so that the linkage 160 forms a tendency to move away from the rotating table 110. When the lifting and reset assembly 500 drives the linkage 160 to rise, the push spring 180 is compressed, which can make the reset action of the linkage 160 and its connected film support column 140 and trigger column 150 more stable. In addition, after the lifting and reset assembly 500 releases the linkage 160, under the action of the push spring 180, the linkage 160 can form a tendency to move downward away from the rotating table, so that the linkage 160 moves closer to the self-locking mechanism 170, ensuring that the self-locking mechanism 170 can effectively self-lock the linkage 160, thereby improving the reliability of the overall structure during operation. Optionally, the push spring 180 is arranged outside the trigger column 150.

[0050] Understandably, the reference Figure 3The side pressure laminating assembly 400 further includes a translation rail 440, a slider 450, and a side pressure elastic member 460. The translation rail 440 is connected to the output end of the side pressure rotating mechanism 420. The slider 450 is connected to the translation rail 440 and can slide relative to the translation rail 440. One end of the side pressure elastic member 460 is connected to the slider 450 so that the slider 450 forms a tendency to move closer to the product fixture 130 at the side pressure station. The side pressure roller 430 is rotatably connected to the slider 450, and the rotation axis of the side pressure roller 430 is perpendicular to the horizontal plane. During operation, under the action of the side pressure elastic member 460 pushing the slider 450, the side pressure roller 430 can form a floating effect. The side pressure roller 430 can achieve corresponding contouring movement according to the circumferential curved surface of the product to be laminated, thereby effectively improving the laminating effect of the side pressure laminating assembly 400 on the product to be laminated. The side pressure rotation mechanism 420 can be a mechanism such as a rotary motor that can drive the rotational motion. The translational slide 440 is provided with an angle sensor for detecting the real-time rotation angle of the translational slide 440 when driven by the rotary motor, thereby improving the control accuracy and the film sticking accuracy.

[0051] Understandably, the reference Figure 3 The side-pressing laminating assembly 400 also includes a side-pressing translation mechanism 470, which is connected to the side-pressing rotation mechanism 420. The side-pressing translation mechanism 470 is used to drive the slider 450 away from the product jig 130 at the side-pressing station, that is, to move the two side-pressing rollers 430 away from each other so that their horizontal projections are located around the horizontal projection of the product jig 130. When the side-pressing lifting mechanism 410 is driven to lift and lower, it can prevent the side-pressing rollers 430 from colliding with the product jig 130, thereby improving the operational reliability of the entire film laminating device.

The specific film pasting process is as follows: one of the longitudinal pressing assemblies first applies film to the two opposite sides of the product to be pasted, one of the lateral pressing assemblies applies film to the circumferential curved surfaces at the edges of the two already filmed sides of the product to be pasted, and the other longitudinal pressing assemblies then apply film to the other two sides of the product to be pasted, and the other lateral pressing assemblies then apply film to the circumferential curved surfaces at the edges of the other two sides of the product to be pasted. By applying film to the sides of the product to be pasted in batches first, and then applying film to the circumferential curved surfaces at the edges of the sides, the large side areas can provide a stable positioning basis for the relatively small axial curved surface areas, thereby effectively improving the film pasting effect.
