For example, an automatic laminating machine uses a pressing roller to apply film to a workpiece. However, due to the fixed length of the roller, it cannot effectively roll over raised areas and surrounding areas, making it unsuitable for laminating films on complex surfaces.

[0004] Therefore, it is necessary to make further improvements in the prior art. Summary of the Invention

[0083] The oblique-sticking dual-size roller mechanism and the film-sticking equipment having the same according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0084] Reference Figures 1 to 8 As shown, a diagonally attached dual-size roller mechanism is provided according to an embodiment of the present invention.

[0085] An oblique-sticking dual-size roller mechanism according to an embodiment of the present invention includes a connecting seat 10 , a mounting plate 20 , a film-absorbing plate 21 , a first driving member 22 , a roller assembly 30 and a second driving member 35 .

[0086] The upper end of the connecting seat 10 is suitable for connecting to a machine.

[0087] The mounting plate 20 is connected below the connecting base 10 and extends in a horizontal direction.

[0088] The film absorbing plate 21 is disposed below the mounting plate 20 and is used to absorb the film to be attached.

[0089] The first driving member 22 is provided on one side of the connecting seat 10, and the output end is connected to one end of the mounting plate 20, so as to drive the mounting plate 20 and the film absorbing plate 21 to pivot so that the film absorbing plate 21 and the surface of the workpiece to be filmed form an angle.

[0090] The roller assembly 30 includes a first vertical plate 31, a roller frame 32, a first roller 33 and a second roller 34. The first vertical plate 31 is vertically installed at the other end of the mounting plate 20. The roller frame 32 is rotatably installed on one side of the first vertical plate 31. The first roller 33 and the second roller 34 are adjacently arranged on the roller frame 32. The first roller 33 is longer than the second roller 34.

[0091] The roller frame 32 can be adjusted between a first position and a second position. When the roller frame 32 is in the first position, the horizontal height of the first roller 33 is lower than that of the second roller 34. When the roller frame 32 is in the second position, the horizontal height of the second roller 34 is lower than that of the first roller 33.

[0092] The second driving member 35 is disposed on one side of the first vertical plate 31 and is used to drive the roller frame 32 to switch between the first position and the second position.

[0093] Based on the above, the film-absorbing plate 21 is driven by the first driving member 22 to form an angle with the surface of the workpiece to be filmed, which can adapt to the film-pasting scenario of non-planar or inclined surfaces, effectively reduce bubbles, wrinkles or loose fitting problems caused by improper angles during the film-pasting process, and improve the film-pasting accuracy. The roller assembly 30 integrates the first roller 33 (long) and the second roller 34 (short). The position of the roller frame 32 is adjusted by the second driving member 35, and the appropriate roller can be dynamically selected according to the width or protruding structure of the area to be filmed: this mechanism takes into account the film-pasting accuracy, flexibility and automation efficiency through the collaborative design of angle adjustment and dual-size rollers, and is particularly suitable for the film-pasting needs of complex structure surfaces in the fields of consumer electronics, automotive interiors, etc.

[0094] Preferably, in one embodiment of the present invention, a connecting plate 11 is provided at the lower end of the connecting seat 10, a first connecting member 111 is provided at the lower end of the connecting plate 11, and a second connecting member 23 is provided at the upper end of the mounting plate 20, and the first connecting member 111 and the second connecting member 23 are rotatably connected.

[0095] In this way, the rotating connection structure allows the connection seat 10 and the mounting plate 20 to rotate relative to each other, thereby facilitating the angles of the mounting plate 20 and the film absorbing plate 21 and facilitating the film application process.

[0096] Preferably, in one embodiment of the present invention, the first driving member 22 includes a second vertical plate 221 , a first driving cylinder 222 , a third connecting member 223 and a fourth connecting member 224 .

[0097] The second vertical plate 221 is connected to one side of the connecting seat 10;

[0098] The first driving cylinder 222 is provided on the second vertical plate 221;

[0099] The third connecting member 223 is connected to the output end of the first driving cylinder 222;

[0100] The fourth connection frame is mounted on the mounting plate 20 , and an upper end thereof is rotatably connected to the third connection member 223 .

[0101] In this way, the first drive cylinder 222, through the rotational coordination of the third connecting member 223 and the fourth connecting member 224, transmits its power directly to the mounting plate 20, reducing energy loss in the intermediate transmission link and improving response speed and control accuracy. The second riser 221, serving as the mounting support for the drive cylinder, is laterally integrated with the connecting base 10, effectively utilizing longitudinal space and avoiding lateral expansion resulting in bulk, making it suitable for installation environments with limited space.

[0102] Preferably, in one embodiment of the present invention, two extensions 311 are provided on the side of the first vertical plate 31 , and the two extensions 311 are spaced apart along the width direction of the first vertical plate 31 , and the roller frame 32 is rotatably connected between the two extensions 311 .

[0103] In this way, by providing the two extension portions 311 , the roller frame 32 can be pivotally mounted between the two extension portions 311 and located on one side of the mounting plate 20 , which is beneficial for subsequent film application.

[0104] Preferably, in one embodiment of the present invention, the second driving member 35 includes a second driving cylinder 351 , a fifth connecting member 352 , a sixth connecting member 353 and a seventh connecting member 354 .

[0105] The second driving cylinder 351 is disposed on the second vertical plate 221 .

[0106] The fifth connecting member 352 is connected to the output end of the second driving cylinder 351 .

[0107] The upper end of the sixth connecting member 353 is rotatably connected to the fifth connecting member 352 .

[0108] One end of the seventh connecting member 354 is connected to the roller frame 32 , and the other end extends toward one side of the first vertical plate 31 and is rotatably connected to the lower end of the sixth connecting member 353 .

[0109] In this way, the second driving cylinder 351 transmits the thrust of the second driving cylinder 351 to the roller frame 32 through the rotational cooperation of the fifth connecting member 352, the sixth connecting member 353 and the seventh connecting member 354, thereby driving the roller frame 32 to rotate, so as to realize the conversion of the roller assembly 30 between the first position and the second position.

[0110] Advantageously, in another embodiment of the present invention, the first driving cylinder 222 and the second driving cylinder 351 may be pneumatic cylinders, hydraulic cylinders or electric cylinders. Of course, other driving forms may also be used.

[0111] Preferably, in one embodiment of the present invention, two third vertical plates 112 are provided on the relative upper surface of the connecting plate 11, and the two third vertical plates 112 are arranged opposite to each other along the width direction of the connecting plate 11. The upper ends of the two third vertical plates 112 are respectively slidably connected to the side surfaces of the connecting seat 10, so that the connecting plate 11 slides along the height direction of the connecting seat 10.

[0112] In this way, through the sliding connection design between the third vertical plate 112 and the connecting seat 10, the connecting plate 11 can be fine-tuned along the height direction of the connecting seat 10, and can float accordingly with the height of the product surface, thereby avoiding excessive pressure caused by changes in the height of the product surface during the film application process, thereby avoiding damage to the product.

[0113] Preferably, in one embodiment of the present invention, a first mounting hole 12 is provided on the bottom surface of the connecting base 10, and a second mounting hole 24 is provided on the mounting plate 20, and the first mounting hole 12 and the second mounting hole 24 are arranged opposite to each other.

[0114] A buffer column 25 is provided between the connecting base and the mounting plate 20 , one end of the buffer column 25 is inserted into the first mounting hole 12 , and the other end is inserted into the second mounting hole 24 ;

[0115] Elastic members 26 are provided at both ends of the buffer column 25 , and the other end of the elastic member 26 presses against the bottom of the first mounting hole 12 / the second mounting hole 24 .

[0116] In this way, the elastic members 26 at both ends of the buffer column 25 are compressed and deformed, effectively absorbing the vibration energy between the connecting base 10 and the mounting plate 20, thereby preventing damage to the product due to impact during processing. At the same time, the elastic force of the elastic members 26 can push the roller assembly 30 to be stably pressed against the workpiece to be processed. Advantageously, the elastic member 26 is a return spring.

[0117] Preferably, in one embodiment of the present invention, the connecting seat 10 is provided with a limiting column 13 on both sides of the opposite sides, and the limiting column 13 extends laterally. A limiting groove 113 is provided on both sides of the two third vertical plates 112, and the limiting groove 113 extends along the height direction of the third vertical plates 112. The two ends of the limiting column 13 respectively extend into the two limiting grooves 113 to limit the stroke of the mounting plate 20.

[0118] In this way, the matching design of the limiting column 13 and the limiting groove 113 limits the sliding range of the mounting plate 20 through physical constraints, preventing the mounting plate 20 and the upper end component of the mounting plate 20 from moving beyond a preset range.

[0119] Preferably, in one embodiment of the present invention, a plurality of negative pressure holes 211 are distributed on the bottom surface of the film absorbing plate 21 , and the plurality of negative pressure holes 211 are connected to a negative pressure device through an airway to generate negative pressure to adsorb the film to be attached on the bottom surface of the film absorbing plate 21 .

[0120] This airway structure evenly distributes negative pressure, shortening the pressure equilibration time between the film absorbing plate 21 and the film material, enabling rapid adsorption and release, improving production cycle efficiency, and making it suitable for high-frequency film application operations on automated assembly lines. The integrated airway design replaces the traditional multiple independent pipe connections, reducing piping complexity and leak risks. Furthermore, the negative pressure holes 211 are machined directly on the bottom surface of the film absorbing plate 21, making it easy to clean, replace, or adjust the hole layout, reducing maintenance costs.

[0121] On the other hand, a film-sticking device according to an embodiment of the present invention has the oblique-sticking dual-size roller mechanism as described above.

[0122] Based on the above, according to the film laminating equipment provided by the embodiment of the present invention, the first driving member 22 drives the film absorbing plate 21 to form an angle with the surface of the workpiece to be filmed, which can adapt to the film laminating scenarios of non-planar or inclined surfaces, effectively reduce bubbles, wrinkles or loose fitting problems caused by improper angles during the film laminating process, and improve the film laminating accuracy. The roller assembly 30 integrates the first roller 33 (long) and the second roller 34 (short), and the position of the roller frame 32 is adjusted by the second driving member 35. The appropriate roller can be dynamically selected according to the width or protruding structure of the area to be filmed: this mechanism takes into account the film laminating accuracy, flexibility and automation efficiency through the coordinated design of angle adjustment and dual-size rollers, and is particularly suitable for the film laminating needs of complex structure surfaces in the fields of consumer electronics, automotive interiors, etc.
