[0038] Reference Figure 1-19 The figure shows a preferred embodiment of the present invention.

[0039] The large curved surface film laminating machine includes a product loading structure 100, a product conveying structure 200, a film laminating structure, a film material conveying structure 300, a film material stripping and laminating structure and a material unloading structure. The product loading structure 100 extracts the product to the product conveying structure 200. The product conveying structure 200 conveys the product, and after alignment and adjustment, conveys the product to the film laminating structure. The film material conveying structure 300 conveys the film material 600 to the film material stripping and laminating structure. After the film material 600 is stripped, it is conveyed to the film laminating structure. After the film laminating structure laminates the product with the film material 600, it is conveyed to the material unloading structure.

[0040] When the above-mentioned large curved surface film laminating machine is working, the product is loaded through the product loading structure 100 and then transferred to the product conveying structure 200. The product conveying structure 200 then conveys the curved surface product to the film laminating structure. At the same time, the film material conveying structure 300 conveys the film material 600 to the film material stripping and laminating structure. The film material 600 is stripped by the film material stripping and laminating structure and then conveyed to the film laminating structure. After the film laminating structure laminates the curved surface product with the film material 600, it is conveyed to the unloading structure, and finally the product after laminating is collected through the unloading structure. In this way, the entire production and processing is automated, which greatly improves the work efficiency, as well as the laminating effect of the curved surface product and the film material 600, and improves the qualified rate of finished products.

[0041] In this embodiment, the product loading structure 100 includes a loading guide rail 110 and a loading robot 120, and the loading guide rail 110 and the loading robot 120 are arranged in a movable docking manner; the loading robot 120 includes a first suction part 121 and two second suction parts 122, the first suction part 121 is located between the two second suction parts 122, and along the top-down direction, the two second suction parts 122 are arranged in the same horizontal plane, and the first suction part 121 and the second suction part 122 are staggered; when extracting the product, the first suction part 121 and the second suction part 122 respectively contact and adsorb the product.

[0042] The first suction part 121 and the second suction part 122 respectively contact and absorb the product. Since the two second suction parts 122 are arranged in the same horizontal plane from top to bottom, the two second suction parts 122 can synchronously absorb the product, thereby improving the stability of product movement. At the same time, the first suction part 121 and the second suction part 122 are staggered. In this way, for curved products that arch upward or curved products that are recessed downward, the first suction part 121 and the two second suction parts 122 can cooperate to extract the curved products. Finally, the loading robot 120 moves relative to the loading guide rail 110 to transfer the curved products to the next process. This realizes automatic loading of curved products and effectively improves work efficiency.

[0043] The loading robot 120 includes a moving group, which is docked with the loading guide rail 110. The moving group includes a moving rail and a plurality of moving blocks. The moving rail is horizontally extended, and the moving block is docked with the moving rail. The first suction part 121 and the two second suction parts 122 are docked with the moving blocks respectively. When tightened, the moving block and the moving rail are relatively fixed. When loosened, the moving block is relatively movable relative to the moving rail in the horizontal direction. In this way, the relative position of the moving block and the moving rail can be adjusted to meet the film processing requirements of different curved products.

[0044] The moving blocks are arranged at intervals along the length direction of the moving rail, and the moving blocks are arranged in a one-to-one correspondence with the first suction part 121, the second suction part 122 and the auxiliary suction part 123, so as to realize the relative movement of the first suction part 121, the second suction part 122 and the auxiliary suction part 123 with the moving rail respectively.

[0045] The moving block has a transverse groove, and the transverse grooves of each moving block are arranged at the same level. The moving rail runs horizontally through each transverse groove to achieve the docking between the moving block and the moving rail; the moving block has a longitudinal groove, and the auxiliary longitudinal plate runs through the longitudinal groove to achieve height adjustment of the auxiliary longitudinal plate to meet the film processing requirements of different curved products.

[0046] The transverse grooves are arranged horizontally and penetrate horizontally, and the longitudinal grooves are arranged longitudinally and penetrate vertically; the transverse grooves and the longitudinal grooves are arranged in a staggered manner to avoid mutual influence caused by the transverse movement and the longitudinal movement of the moving block.

[0047] The first suction part 121 includes a first transverse plate 124 and a first longitudinal plate 125. The first transverse plate 124 is arranged transversely, and the first longitudinal plate 125 is arranged longitudinally. The first longitudinal plate 125 and the moving block are docked, and the bottom of the first longitudinal plate 125 and the first transverse plate 124 are movably docked. When tightened by the second screwing piece, the first longitudinal plate 125 and the moving block are relatively fixed. When loosened, the first longitudinal plate 125 is relatively movable relative to the moving block along the longitudinal direction. In this way, the height adjustment of the first longitudinal plate 125 is achieved, thereby adjusting the adsorption height of the first suction cup 126 to meet the film processing requirements of different curved products.

[0048] The first suction portion 121 includes a plurality of first suction cups 126. When extracting a product, each first suction cup 126 contacts and adsorbs the product. A first transverse plate 124 is arranged on the upper portion of the first suction cup 126, and a lower portion of the first suction cup 126 is extended in a direction away from the first transverse plate 124. The first transverse plate 124 is extended in a direction perpendicular to the moving rail, and each first suction cup 126 is arranged in sequence and at intervals along the length direction of the first transverse plate 124. In this way, the curved surface product is adsorbed synchronously by each first suction cup 126, thereby improving the adsorption stability of the curved surface product.

[0049] In addition, each first suction cup 126 is arranged along the width direction of the curved product. Since the curvature of the curved product in the width direction is consistent, multiple first suction cups 126 are arranged at the same level to simultaneously adsorb the curved product.

[0050] The second suction part 122 includes a second transverse plate and a second longitudinal plate, the second transverse plate is arranged transversely, the second longitudinal plate is arranged longitudinally, the second longitudinal plate and the moving block are docked, and the bottom of the second longitudinal plate and the second transverse plate are movably docked; when tightening, the second longitudinal plate and the moving block are relatively fixed, and when loosening, the second longitudinal plate is relatively movable relative to the moving block along the longitudinal direction; in this way, the height adjustment of the second longitudinal plate is achieved, thereby adjusting the adsorption height of the second suction cup to meet the film processing requirements of different curved products.

[0051] The second suction part 122 includes a plurality of second suction cups. When extracting a product, each second suction cup contacts and adsorbs the product respectively. A second transverse plate is arranged on the upper part of the second suction cup, and the lower part of the second suction cup is extended in a direction away from the second transverse plate. The second transverse plate is extended in a direction perpendicular to the moving rail, and each second suction cup is arranged in sequence and spaced apart along the length direction of the second transverse plate. In this way, the curved surface product can be adsorbed synchronously by each second suction cup, thereby improving the adsorption stability of the curved surface product.

[0052] In addition, each second suction cup is arranged along the width direction of the curved product. Since the curvature of the curved product in the width direction is consistent, multiple second suction cups are arranged at the same level to simultaneously adsorb the curved product.

[0053] The loading robot 120 includes two auxiliary suction parts 123, and the auxiliary suction part 123 is located between the first suction part 121 and the second suction part 122; along the top-down direction, the first suction part 121, the auxiliary suction part 123 and the second suction part 122 are staggeredly arranged in sequence; in this way, with the cooperation of the first suction part 121, the two auxiliary suction parts 123 and the two second suction parts 122, a larger range of extraction is achieved to meet the extraction requirements of large curved surface products.

[0054] In addition, along the top-down direction, because the first suction part 121, the auxiliary suction part 123 and the second suction part 122 are staggeredly arranged in sequence, the first suction part 121, the auxiliary suction part 123 and the second suction part 122 perform synchronous adsorption on different curved surface areas of the curved product to meet the feeding requirements of large curved surface products.

[0055] The second suction part 122, the auxiliary suction part 123, the first suction part 121, the auxiliary suction part 123 and the second suction part 122 are arranged in sequence. By adjusting the height of the first suction part 121 and the height of the two auxiliary suction parts 123, the extraction requirements of the arched curved surface products and the extraction requirements of the concave curved surface products are met.

[0056] The moving block and the auxiliary suction part 123 are arranged in a one-to-one correspondence. The auxiliary suction part 123 includes an auxiliary longitudinal plate, an auxiliary transverse plate, an auxiliary adjustment plate and a plurality of auxiliary suction cups. The auxiliary longitudinal plate is arranged longitudinally, the upper part of the auxiliary longitudinal plate is docked with the moving block, the inner end of the auxiliary transverse plate is docked with the lower part of the auxiliary longitudinal plate, and the outer end of the auxiliary transverse plate is docked with the auxiliary adjustment plate. Along the length direction of the moving rail, the auxiliary adjustment plate is extended, and along the length direction of the auxiliary adjustment plate, the auxiliary suction cups are arranged in sequence and at intervals. When extracting products, the first suction part 121, the second suction part 122 and the auxiliary suction cups respectively contact and adsorb the products, thereby improving the adsorption stability of curved products.

[0057] At the same time, the auxiliary suction cups are arranged in sequence and spaced apart along the length direction of the curved product, and combined with the first suction cup 126 and the second suction cup, the product can be adsorbed in multiple directions, thereby improving the transfer safety of the curved product.

[0058] The upper part of the auxiliary suction cup is provided with an auxiliary shaft, which is threadedly connected to the auxiliary adjustment plate. The height of each auxiliary suction cup can be adjusted by adjusting the position of the auxiliary shaft relative to the auxiliary adjustment plate to meet the film processing requirements of different curved products.

[0059] The auxiliary suction part 123 includes an adjusting motor, which has an adjusting shaft. The adjusting motor is installed on the outer end of the auxiliary horizontal plate, and the adjusting shaft extends downward to connect the auxiliary adjusting plate. When the adjusting shaft rotates, the auxiliary adjusting plate is driven to swing in the horizontal direction, thereby realizing the angle adjustment between the auxiliary adjusting plate and the movable rail to meet the film processing requirements of different curved products.

[0060] The mobile group is provided with an upper distance monitor and a lower distance monitor, and the upper distance monitor and the lower distance monitor are arranged in correspondence with each other up and down; the loading guide rail 110 has an extraction part, and the extraction part has an extraction surface. When extracting the product, the mobile group moves to the extraction part, and the upper distance monitor and the lower distance monitor are arranged corresponding to the extraction surface respectively; through the upper distance monitor and the lower distance monitor, it is detected whether the mobile group moves to the specified position, ensuring that the first suction part 121, the second suction part 122 and the auxiliary suction part 123 can synchronously absorb the curved surface products, improve the processing accuracy, and improve the qualified rate of the products.

[0061] The loading guide rail 110 includes an upper loading rail 111 and a lower loading rail 112 . The upper loading rail 111 and the lower loading rail 112 are arranged to be butt-jointed with each other up and down. The upper loading rail 111 and the lower loading rail 112 cooperate with each other to improve the supporting stability of the loading guide rail 110 .

[0062] Furthermore, the moving group includes an upper docking part and a lower docking part, the upper docking part is docked with the upper loading rail 111, and the lower docking part is docked with the lower loading rail 112; in this way, when the moving group moves relative to the moving rail, with the cooperation between the upper docking part and the upper loading rail 111, and the cooperation between the lower docking part and the lower loading rail 112, the movement stability is improved, the movement shaking is reduced, thereby improving the transfer safety of the curved product.

[0063] The upper rail 111 for feeding is hollow, the inner end of the upper docking portion is embedded in the interior of the upper rail 111 for feeding, and the outer end of the upper docking portion is extended outward, thereby playing a guiding role.

[0064] The large curved surface loading structure includes a loading rack 130, through which the loading guide rail 110 and the moving group are supported and installed.

[0065] The loading rack 130 includes a loading support cross bar and two loading support longitudinal bars. The two loading support longitudinal bars are arranged in parallel and correspondingly. The lower ends of the loading support longitudinal bars are fixedly arranged, and the two ends of the loading support cross bar are respectively connected to the upper ends of the two loading support longitudinal bars; the loading guide rail 110 is installed with the loading support cross bar; the two loading support longitudinal bars cooperate with the loading support cross bar to enhance the pressure-bearing capacity and ensure the installation of the loading guide rail 110 and the installation of the moving group.

[0066] In this embodiment, the product conveying structure 200 includes a conveying rail 210, a product conveying platform 220 and a conveying motor group 230. The product conveying platform 220 and the conveying rail 210 are arranged in an up-and-down docking arrangement. The conveying motor group 230 is used to control the movement of the product conveying platform 220 relative to the conveying rail 210; the product conveying platform 220 includes a base 222 and a bearing seat 221. The bearing seat 221 and the base 222 are arranged in an up-and-down docking arrangement. The base 222 and the conveying rail 210 are arranged in an up-and-down docking arrangement. The bearing seat 221 has a bearing surface for bearing curved products, and the bearing surface is arranged in a curved shape.

[0067] When conveying curved products, the products are placed on the supporting seat 221. Since the supporting surface is arranged in a curved shape, the contact area between the supporting seat 221 and the curved product is increased, which facilitates the placement of the curved product. Then, the product conveying platform 220 is controlled to move relative to the conveying guide rail 210 through the conveying motor group 230 to achieve synchronous movement of the base 222 and the supporting seat 221. Under the action of the base 222, the movement of the supporting seat 221 is more stable. At the same time, through the cooperation between the conveying guide rail 210, the product conveying platform 220 and the conveying motor group 230, the automatic conveying of curved products is realized, which effectively improves work efficiency.

[0068] The bearing seat 221 has a bearing groove, which is arranged in a curved shape and is used to place curved products. The product conveying platform 220 includes two side reinforcement seats 240. Along the length direction of the bearing seat 221, the two side reinforcement seats 240 are respectively arranged at the two ends of the bearing seat 221. The bottom of the side reinforcement seat 240 is connected to the base 222 in a docking arrangement, and the top of the side reinforcement seat 240 extends to the inside of the bearing groove and presses the curved product. In this way, under the action of the two side reinforcement seats 240, the placement stability of the curved product is enhanced to avoid the curved product accidentally leaving the bearing seat 221 during movement.

[0069] The side reinforcement seat 240 includes a side base 241, a side reinforcement motor 242 and a side extrusion seat 243. The side base 241 is installed with the base 222, the side reinforcement motor 242 is installed with the side base 241, and the side reinforcement motor 242 is used to drive the side extrusion seat 243 to move toward or away from the bearing slot; when reinforcing, the side extrusion seat 243 moves toward the bearing slot until the side extrusion seat 243 presses against the curved product; in this way, the movement of the side extrusion seat 243 is controlled by the side reinforcement motor 242 to achieve the reinforcement and removal of the curved product.

[0070] The side base 241 includes a side bottom plate and a side longitudinal plate. The side bottom plate is installed on the base 222. The side longitudinal plate is arranged longitudinally. The bottom of the side longitudinal plate is fixedly connected to the side bottom plate. The top of the side longitudinal plate is extended upward. The side reinforcement motor 242 is installed on the side longitudinal plate. The installation of the side reinforcement motor 242 is realized and the installation of the side extrusion seat 243 is facilitated.

[0071] The side longitudinal plate has a plurality of side mounting grooves 244 arranged longitudinally, and each side mounting groove 244 is arranged in sequence, so that the side reinforcement motor 242 is installed in different side mounting grooves 244 to achieve height adjustment of the side reinforcement motor 242, thereby achieving installation height adjustment of the side extrusion seat 243 to meet different film processing requirements.

[0072] The side extrusion seat 243 includes two side extrusion columns 245 and a side extrusion plate 246. The side extrusion plate 246 is arranged in a strip shape, and the side reinforcement motor 242 is used to drive the side extrusion plate 246 to move toward or away from the bearing groove; the side extrusion columns 245 are arranged longitudinally, and the two side extrusion columns 245 are arranged in parallel and spaced apart. The side extrusion plate 246 has a side extrusion surface facing the bearing groove, and the two side extrusion columns 245 are respectively arranged in abutment with the side extrusion surfaces; such arrangement of the side extrusion columns 245 helps to increase the contact area between the side extrusion columns 245 and the curved product, thereby enhancing the reinforcement effect of the side extrusion columns 245; in addition, under the action of the side extrusion plate 246, the two side extrusion columns 245 are synchronously driven to move, so that the two side extrusion columns 245 synchronously reinforce the curved product, thereby improving the placement stability of the curved product.

[0073] The bearing groove has a limiting plate 260, and the product conveying platform 220 includes at least one front reinforcement seat 250. The bottom of the front reinforcement seat 250 is connected to the base 222 in a docking arrangement, and the top of the front reinforcement seat 250 extends to the inside of the bearing groove to press the curved surface product. The front reinforcement seat 250 and the limiting plate 260 clamp the curved surface product; under the cooperation of the limiting plate 260 and the front reinforcement seat 250, the placement stability of the curved surface product is improved.

[0074] At the same time, the limiting plate 260, the front reinforcement seat 250 and the two side reinforcement seats 240 reinforce the curved product in different directions, and reinforce the front, back, left and right of the curved product.

[0075] The front reinforcement seat 250 includes a front base, a front reinforcement motor and a front extrusion seat. The front base is installed with a base 222, and the front reinforcement motor is installed with the front base. The front reinforcement motor is used to drive the front extrusion seat to move toward or away from the bearing slot; when reinforcing, the front extrusion seat moves toward the bearing slot until the front extrusion seat presses against the curved product; in this way, the side extrusion seat 243 is controlled to move by the front reinforcement motor to achieve reinforcement and picking up of the curved product.

[0076] The product conveying platform 220 includes a plurality of front reinforcement seats 250 , which are sequentially spaced apart along the length direction of the bearing seat 221 , so as to realize multi-region reinforcement of the curved surface product.

[0077] The front extrusion seat includes two front extrusion columns and a front extrusion plate. The front extrusion plate is arranged in a strip shape, and the front reinforcement motor is used to drive the front extrusion plate to move toward or away from the bearing groove; the front extrusion columns are arranged longitudinally, and the two front extrusion columns are arranged in parallel and spaced apart. The front extrusion plate has a front extrusion surface facing the bearing groove, and the two front extrusion columns are respectively arranged in a butt connection with the front extrusion surface; such an arrangement of the front extrusion columns helps to increase the contact area between the front extrusion columns and the curved product, and enhance the reinforcement effect of the front extrusion columns; in addition, under the action of the front extrusion plate, the two front extrusion columns are synchronously driven to move, so that the two front extrusion columns synchronously reinforce the curved product, thereby improving the placement stability of the curved product.

[0078] The bearing seat 221 has a plurality of alignment grooves, which are arranged in one-to-one correspondence with the front extrusion columns, and the alignment grooves and the bearing grooves are connected. When reinforcing, the front extrusion columns are embedded in the alignment grooves and press against the curved product. In this way, under the action of the alignment grooves, the displacement of the front extrusion columns during the reinforcement process is avoided, thereby ensuring the reinforcement of the curved product by the front extrusion columns.

[0079] The base 222 extends upward to form a first support seat and two second support seats. The first support seat is between the two second support seats. Along the top-down direction, the two second support seats are arranged in the same horizontal plane, and the first support seat and the second support seat are staggered; the bearing seat 221 and the first support seat are arranged in an up-down docking arrangement, and the bearing seat 221 and the two second support seats are arranged in an up-down docking arrangement; the bearing seat 221 is supported and fixed by the cooperation between the first support seat and the two second support seats. In addition, along the top-down direction, since the first support seat and the second support seat are staggered, it is convenient to fully support the bearing seat 221, thereby ensuring the support and fixation of the bearing seat 221 which is arranged in a curved surface.

[0080] The first support seat includes a bottom support seat and a lifting seat. The bottom support seat is docked with the base 222. The bottom of the lifting seat is docked with the bottom support seat through a lifting motor, and the top of the lifting seat is docked with the bearing seat 221. In this way, the height of the lifting seat can be adjusted through the lifting motor to meet the reinforcement requirements of the arched curved surface products and the processing requirements of the sunken curved surface products.

[0081] The large curved surface feeding structure includes a product positioning frame 270, which includes a positioning cross bar and two positioning longitudinal bars. The positioning longitudinal bars are arranged longitudinally, and the two positioning longitudinal bars are arranged in parallel and spaced apart. The lower part of the positioning longitudinal bar is fixedly arranged, and the two ends of the positioning cross bar are respectively connected to the upper parts of the two positioning longitudinal bars; the positioning cross bar is provided with two product locators 271, and the product conveying platform 220 is located below the product locators 271. When the product conveying platform 220 moves relative to the conveying guide rail 210, the two product locators 271 respectively monitor the placement position of the curved surface product; in this way, when the product conveying platform 220 moves relative to the conveying guide rail 210 to convey the curved surface product, the placement position of the curved surface product is monitored by the two product locators 271, thereby improving the placement accuracy of the curved surface product.

[0082] The product locator 271 may be a CCD camera, which can take a picture of the edge of the curved product and analyze whether the placement position is offset. If not, corresponding adjustments can be made through the subsequent XXY adjustment table.

[0083] The product conveying platform 220 includes an XXY adjustment platform, and the base 222 and the XXY adjustment platform are arranged to be connected up and down; the XXY adjustment platform includes an X-axis adjustment member, a Y-axis adjustment member and an angle adjustment member, and the X-axis adjustment member, the Y-axis adjustment member and the angle adjustment member are respectively connected to the base 222, the X-axis adjustment member is used to adjust the base 222 to move along the X direction, the Y-axis adjustment member is used to adjust the base 222 to move along the Y direction, and the angle adjustment member is used to adjust the horizontal angle of the base 222; the position adjustment of the base 222 is realized to ensure the accuracy of subsequent film pasting.

[0084] In this embodiment, the film material conveying structure 300 includes a film material loading guide rail 310, a film material conveying platform 320 and an optical fiber alignment component 330. The film material conveying platform 320 is arranged corresponding to the film material loading guide rail 310, and the film material conveying motor drives the film material conveying platform 320 to reciprocate relative to the film material loading guide rail 310; the composite film includes a film material 600 and a base film, the film material 600 is attached to the base film, and the composite film is mounted on the film material conveying platform 320 in a roll shape. The film material 600 has a leading edge, and the optical fiber alignment component 330 detects the leading edge of the film material 600. The optical fiber alignment component 330 controls the film material conveying platform 320 to start or stop conveying the composite film; after the film material 600 is positioned, the film material conveying platform 320 is controlled to move to the film material stripping and pasting structure, and the film material stripping and pasting structure peels the film material 600 off the base film.

[0085] In this way, since the composite film is arranged in a roll on the film material conveying platform 320, when the film material 600 is loaded, the film material conveying motor drives the film material conveying platform 320 to move relative to the film material loading guide rail 310 until it moves to the film material stripping and pasting structure. At the same time, the film material conveying platform 320 conveys the composite film; and the optical fiber alignment component 330 detects the leading edge of the film material 600, controls the film material conveying platform 320 to stop conveying the composite film, and locates the position of the film material 600, thereby ensuring the accuracy of subsequent extraction and pasting of the film material 600, improving the accuracy of film material 600 loading, and improving the qualified rate of finished products.

[0086] That is to say, when loading the film material 600, the film material conveying platform 320 moves to the film material peeling and laminating structure. After the film material 600 peels off the base film, the film material conveying platform 320 is reset. Then, the laminating structure laminates the film material 600 to the curved product. The film material conveying platform 320 is reset to avoid affecting the work of the laminating structure. At the same time, it saves the overall occupied area of ​​the large curved surface laminating machine.

[0087] The film material conveying platform 320 includes a conveyor belt 321 , a supply roller 322 and a recovery roller 323 . The conveyor belt 321 is arranged horizontally to facilitate the flattening of the film material 600 and the subsequent extraction of the film material 600 .

[0088] The inner end of the composite film is rolled and arranged on the supply roller 322, and the outer end of the composite film is laid flat on the conveyor belt 321 and extends to connect with the recovery roller 323; during transportation, the supply motor drives the supply roller 322 to rotate and release the composite film, and the recovery motor drives the recovery roller 323 to rotate and recover the bottom film; in this way, the supply of the film material 600 and the recovery of the bottom film are realized, and the whole process is automated, which reduces manual participation and improves work efficiency.

[0089] The supply motor and the recovery motor are arranged to rotate synchronously, and the supply motor rotates forward and the recovery motor rotates reversely, or the supply motor rotates reversely and the recovery motor rotates forward; the supply of the composite film and the recovery of the bottom film are realized, ensuring that the composite film is in a tensioned state, which is convenient for separating the film material 600 from the bottom film.

[0090] The film material conveying platform 320 includes a guide roller 324, which is arranged to rotate. The guide roller 324 is located between the conveyor belt 321 and the supply roller 322. The composite film contacts the outer surface of the guide roller 324 and then extends to the conveyor belt 321. Under the action of the guide roller 324, it is easy to guide the composite film to extend onto the conveyor belt 321.

[0091] The guide roller 324 is arranged in a cylindrical shape, and because the guide roller 324 is arranged to rotate, when the composite film is transported, the damage to the composite film by the guide roller 324 is reduced, and the friction between the guide roller 324 and the composite film is reduced, which facilitates the transportation of the composite film.

[0092] The top of the guide roller 324 forms a conveying end surface, and the upper end surface of the conveyor belt 321 is arranged flush with the conveying end surface; this facilitates the coordination between the guide roller 324 and the conveyor belt 321, and facilitates the transition of the composite film from the guide roller 324 to the conveyor belt 321. At the same time, it reduces the occurrence of creases in the composite film, which affects the subsequent bonding effect of the film material 600.

[0093] The film material conveying platform 320 includes a plurality of auxiliary rollers 325, each of which is located between the conveyor belt 321 and the recovery roller 323. The composite film sequentially contacts each of the auxiliary rollers 325 and then extends to dock with the recovery roller 323. From top to bottom, each of the auxiliary rollers 325 is gradually staggered downward. In this way, under the action of each of the auxiliary rollers 325, the bottom film is guided to the recovery roller 323 in layers, which is convenient for the recovery of the bottom film.

[0094] The film material conveying platform 320 includes a film material conveying upper seat, a film material conveying lower seat and a film material adjusting member. The film material conveying lower seat is docked with the film material feeding guide rail 310, and the film material conveying upper seat and the film material conveying lower seat are docked up and down. The conveyor belt 321, the supply roller 322 and the recovery roller 323 are respectively installed on the film material conveying upper seat; the film material adjusting member is used to adjust the relative position of the film material conveying upper seat and the film material conveying lower seat; in this way, the relative position of the film material conveying upper seat and the film material conveying lower seat is adjusted through the film material adjusting member, thereby adjusting the position of the film, so as to make the subsequent bonding more accurate.

[0095] The film material loading guide rail 310 includes two film material track bars arranged side by side and a film material platform driving motor. One end of the screw rod is connected to the film material platform driving motor, and the other end of the screw rod is connected to the film material conveying lower seat; the film material conveying lower seat is synchronously connected to the two film material track bars; under the action of the two film material track bars, the film material conveying lower seat moves more smoothly.

[0096] The screw rod is located between the two film material track bars, thus reducing the overall occupied area. At the same time, the screw rod driving force is effectively dispersed by the two film material track bars, making the film material conveying lower seat move more smoothly.

[0097] The conveyor belt 321 includes a conveyor plate and a separation plate. The conveyor plate is arranged horizontally, the inner end of the separation plate is connected to the conveyor plate, and the outer end of the separation plate is arranged gradually tilted upward; the composite film is synchronously laid flat on the conveyor plate and the separation plate; the film material 600 has a rear edge, and when the rear edge of the film material 600 moves to the separation plate, the rear edge of the film material 600 is separated from the bottom film; under the action of the separation plate, it is convenient for the subsequent film stripping and laminating structure to peel the film material 600 off the bottom film.

[0098] The optical fiber alignment assembly 330 includes an optical fiber support frame and an optical fiber component. The optical fiber component emits laser to detect the leading edge of the film material 600. The lower part of the optical fiber support frame is fixedly arranged, and the optical fiber component is installed on the upper part of the support frame. Under the action of the optical fiber support frame, the installation of the optical fiber component is facilitated.

[0099] Furthermore, the optical fiber support frame includes an optical fiber base 331, an optical fiber movable seat 333 and a first optical fiber motor 332.

[0100] The optical fiber movable seat 333 includes a first optical fiber seat, a second optical fiber seat and a second optical fiber motor. The first optical fiber seat is docked with the optical fiber guide rail. The first optical fiber seat and the second optical fiber seat are docked. The second optical fiber motor has an optical fiber drive shaft, which is arranged longitudinally. The rotation of the optical fiber drive shaft drives the second optical fiber seat to move longitudinally relative to the first optical fiber seat. The second optical fiber seat is installed on the optical fiber component. The position adjustment of the optical fiber component along the longitudinal direction is realized to meet different monitoring needs.

[0101] In this embodiment, the film material stripping and film pasting structure 400 includes a film material stripping and film pasting structure and a film pasting structure.

[0102] The film stripping and laminating structure includes a bonding roller mechanism 420, a yielding roller mechanism 410, a steel strip 500 and a bonding guide rail. The bonding roller mechanism 420 and the bonding guide rail are butt-jointed, and two ends of the steel strip 500 are butt-jointed with the bonding roller mechanism 420 and the yielding roller mechanism 410 respectively. The steel strip 500 is horizontally arranged, and the steel strip 500 has an adhesive layer 510, and the adhesive layer 510 is used to bond the film material 600; the bonding roller mechanism 420 includes a bonding roller body 421, and the bonding roller body 421 is above the steel strip 500; when stripping the film, the bonding roller body 421 moves along the bonding guide rail, and the bonding roller body 421 applies an extrusion force downward to make the adhesive layer 510 bond to the film material 600.

[0103] When the film material 600 is being stripped, the film material conveying structure 300 conveys the film material 600 to the bottom of the steel strip 500. Since the steel strip 500 is arranged horizontally and has an adhesive layer 510, the adhesive roller mechanism 420 moves along the adhesive guide rail, so that the adhesive roller body 421 applies an extrusion force downward, so that the adhesive layer 510 adheres to the film material 600. Finally, the adhesive roller body 421 is reset, and with the cooperation of the yield roller mechanism 410 and the compensation lifting mechanism 430, the steel strip 500 drives the film material 600 to separate from the base film, thereby stripping the film material 600. In this way, automatic stripping is achieved, damage to the film material 600 is reduced, and the efficiency of the subsequent overall film pasting operation is improved.

[0104] The bonding roller mechanism 420 includes a bonding roller motor 425, a bonding roller seat 422 and a bonding roller moving frame 424. The bonding roller seat 422 has a bonding roller guide rail 423, and the bonding roller moving frame 424 is arranged in a butt connection with the bonding roller guide rail 423; the bonding roller body 421 is provided with the bonding roller moving frame 424, and the bonding roller motor 425 is used to drive the bonding roller body 421 to reciprocate toward or away from the steel strip 500; through the longitudinal movement of the bonding roller body 421, the steel strip 500 is squeezed and released, and the film material 600 is adhered and the film material 600 is peeled off.

[0105] The bonding roller mechanism 420 includes a film material separation roller 426, which is arranged corresponding to the bonding roller body 421, and a separation gap is formed between the film material separation roller 426 and the bonding roller body 421. The steel strip 500 runs through the separation gap, and the steel strip 500 has a first thickness. The bonding layer 510 is attached to the steel strip 500 to form a second thickness. The separation gap has a third thickness, which is greater than the first thickness and less than the second thickness. In this way, when stripping the film, the composite film moves through the separation gap, the bottom film passes through the separation gap, and the film material 600 is blocked and separated from the bottom film, which facilitates the separation of the film material 600 from the bottom film.

[0106] The film material separation roller 426 and the bonding roller body 421 are arranged in an up-down staggered manner; thus, they play a guiding role and facilitate the separation of the film material 600 from the base film.

[0107] The large curved steel strip adhesive film structure includes a horizontal detector, which emits a horizontal detection line, and the horizontal detection line is arranged at the same level as the steel strip 500; in this way, the horizontal detection of the steel strip 500 is achieved through the horizontal detector, which is convenient for the subsequent bonding and stripping of the film material 600.

[0108] The level detector can be an infrared sensor or a CCD camera.

[0109] The film material 600 is transferred through the film material conveying structure 300, which includes a conveyor belt 321. The conveyor belt 321 includes a conveyor plate and a separation plate. The film material 600 is laid flat on the conveyor plate, which is arranged horizontally. The inner end of the separation plate is butted against the conveyor plate, and the outer end of the separation plate is gradually inclined upward. When peeling the film, the bonding roller body 421 moves from the outer end to the inner end of the separation plate until the conveyor plate is moved, and the bonding layer 510 is fully in contact with the film material 600. In this way, it is easy for the bonding layer 510 to adhere to the film material 600.

[0110] The large curved steel belt film bonding structure includes a bonding frame, the bottom of the bonding frame is fixedly arranged, and the top of the bonding frame forms a bonding guide rail; a bonding area is formed inside the bonding frame, and the film material conveying structure 300 conveys the film material 600 to the bonding area, and the bonding roller body 421 is in the bonding area; it is convenient for the installation of the bonding roller mechanism 420, the yield roller mechanism 410 and the bonding roller mechanism 420.

[0111] The steel strip 500 has a first width, the adhesive layer 510 has a second width, and the film material 600 has a third width. The first width is greater than the second width, and the second width is greater than the third width. In this way, the adhesive layer 510 fully covers the steel strip 500, and the adhesive layer 510 fully adheres to the film material 600, thereby improving the film stripping effect.

[0112] The give-way roller mechanism 410 includes a give-way roller motor and a give-way roller body. The give-way roller motor is used to drive the give-way roller body to move back and forth in the longitudinal direction; the give-way roller body is above the bonding roller body 421; in this way, the give-way roller body and the bonding roller body 421 are staggered, so that when the bonding layer 510 is bonding the film material 600, the composite film forms an angle difference, so that the film material 600 to be adhered is staggered with other film materials 600, which is convenient for peeling off the film material 600.

[0113] The compensation lifting mechanism 430 includes a compensation lifting motor and a compensation roller body. The compensation lifting motor is used to drive the compensation roller body to move back and forth in the longitudinal direction; the bonding roller body 421 is located between the giving way roller body and the compensation roller body, and the compensation roller body is located above the bonding roller body 421; when the film material 600 is bonded to the product, the adhesive layer 510 of the steel strip 500 is prevented from fully bonding to the feeding platform, so as to facilitate the resetting of the steel strip 500.

[0114] In this embodiment, the film pasting structure includes a bonding roller mechanism 420, a product conveying platform 220 and a bonding guide rail. The bonding roller mechanism 420 and the bonding guide rail are arranged in a docking manner.

The product conveying platform 220 has a bearing surface for bearing curved products, and the bearing surface is arranged in a curved shape. When the bonding roller mechanism 420 moves along the bonding guide rail, it simultaneously moves downward to apply a resisting force to the film material 600, so that the film material 600 adheres to the curved product.

[0115] When the film laminating operation is performed, since the film material 600 is located above the product conveying platform 220, the bonding roller mechanism 420 is located above the film material 600, and the curved surface product is placed on the product conveying platform 220. When the film laminating operation is performed, the bonding roller mechanism 420 moves along the bonding guide rail and moves horizontally. When the bonding roller mechanism 420 moves horizontally, it simultaneously moves downward to apply a resisting force to the film material 600. According to the change of the bearing surface, the downward moving distance of the bonding roller mechanism 420 also changes accordingly, and finally the film material 600 and the curved surface product are arranged in a fitting manner; in this way, automatic film laminating of curved surface products is realized, and work efficiency is effectively improved. At the same time, the bonding roller mechanism 420 moves along the bonding guide rail and moves longitudinally to realize film laminating of curved surface products, realize full film laminating, avoid the occurrence of bubbles and wrinkles, and thus improve the qualified rate of finished products.

[0116] The bonding roller mechanism 420 includes a bonding roller motor 425, a bonding roller seat 422 and a bonding roller moving frame 424. The bonding roller seat 422 has a bonding roller guide rail 423, and the bonding roller moving frame 424 is arranged in a butt connection with the bonding roller guide rail 423. The bonding roller body 421 is provided with the bonding roller moving frame 424. The bonding roller motor 425 is used to drive the bonding roller body 421 to apply a pressure along the film material 600 or to remove the pressure, so as to achieve a bonding arrangement between the film material 600 and the curved product.

[0117] The large curved surface film pasting structure includes a counterweight mechanism 440, and the film material 600 is bonded to the steel strip 500, and the steel strip 500 is connected to the counterweight mechanism 440; when the bonding roller body 421 applies a pressure along the film material 600 or cancels the pressure, it drives the counterweight mechanism 440 to move back and forth in the longitudinal direction; under the action of the counterweight mechanism 440, it is convenient to reset the steel strip 500, and effectively buffer the pressure applied by the bonding roller mechanism 420 when moving downward, so that the bonding roller mechanism 420 moves downward more smoothly.

[0118] The steel strip 500 is respectively connected to the giving way roller mechanism 410 and the compensating lifting mechanism 430, and the bonding roller mechanism 420 is located between the giving way roller mechanism 410 and the compensating lifting mechanism 430; when applying the film, the bonding roller body 421 moves along the direction from the compensating lifting mechanism 430 to the giving way roller mechanism 410 and applies a downward pressure; when the curved surface product is arranged to be convex upward, the giving way roller mechanism 410 moves to the highest point, and with the movement of the bonding roller body 421, the giving way roller mechanism 410 gradually descends synchronously; in this way, when applying the film, bubbles and wrinkles are avoided, thereby improving the qualified rate of finished products.

[0119] When the curved product is arranged in a downward concave direction, the giving way roller mechanism 410 and the compensating lifting mechanism 430 are arranged correspondingly in the horizontal direction to fix the steel strip 500 and arrange the film material 600 horizontally, which is convenient for the film material 600 to correspond to the curved product and for the bonding roller body 421 to press the steel strip 500 to make the film material 600 fit the curved product.

[0120] The steel strip 500 is respectively connected to the counterweight mechanism 440, the yield roller mechanism 410 and the compensation lifting mechanism 430, and the counterweight mechanism 440, the yield roller mechanism 410 and the compensation lifting mechanism 430 are arranged in sequence; when the steel strip 500 is compressed, the counterweight mechanism 440 is driven to rise, and when the pressure of the steel strip 500 is removed, the counterweight mechanism 440 descends to reset the steel strip 500; in this way, the counterweight mechanism 440, the yield roller mechanism 410, the bonding roller motor 425 and the compensation lifting mechanism 430 cooperate to achieve film pasting and avoid bubbles and wrinkles, thereby improving the qualified rate of finished products.

[0121] The counterweight mechanism 440 includes a counterweight block 441. When the steel strip 500 is under pressure, the counterweight block 441 is driven to rise. When the resistance of the steel strip 500 is removed, the counterweight block 441 descends to reset the steel strip 500. The large curved film-sticking structure includes a fixed block 450. The steel strip 500 is docked with the fixed block 450. When the counterweight block 441 rises, the fixed block 450 gradually descends under the action of its own weight. When the counterweight block 441 descends, the fixed block 450 is driven to rise. Through the cooperation of the counterweight block 441 and the fixed block 450, whether it is a film stripping operation or a film sticking operation, the bonding roller mechanism 420 moves up and down more smoothly to avoid bubbles and wrinkles, thereby improving the qualified rate of finished products.

[0122] During the film pasting operation, the two side reinforcement seats 240 and the plurality of front reinforcement seats 250 cooperate to reinforce the curved surface product in the bearing seat 221, thereby preventing the curved surface product from being misaligned during film pasting, thereby improving the qualified rate of finished products.
