[0027] The following further describes the embodiments of the present application in conjunction with the accompanying drawings. To facilitate understanding and explanation of the embodiments of the present application, a three-dimensional coordinate system is established in some of the accompanying drawings, with the X-axis being the first direction, the Z-axis being the second direction, and the Y-axis being the third direction, with the X-axis, Y-axis, and Z-axis directions being perpendicular to each other.

[0028] See Figure 1 and Figure 2 The present embodiment provides a film laminating device 100 for laminating a film 200 to a workpiece 300. The film 200 may be a green silicon film, for example. The film 200 used in this embodiment is a single-layer film and is not attached to other film layers such as release paper. The workpiece 300 may be an electronic product housing, such as a mini computer housing. In this embodiment, the uncut film 200 has a greater width along the Y-axis than the workpiece 300. The film laminating device 100 includes a frame 10, a film supply mechanism 20, a film laminating mechanism 30, a material transfer mechanism 40, and a film cutting mechanism 50.

[0029] Specifically, the frame 10 includes at least one supporting table and one supporting vertical plate, which are used to provide support for the film supply mechanism 20, the film laminating mechanism 30, the material moving mechanism 40 and the film cutting mechanism 50. The frame 10 can also be used to set up structures such as an electrical control box, an operation panel, an alarm light, and a safety grating.

[0030] The film supply mechanism 20 is provided on the frame 10, and includes a discharge assembly 21 and a receiving assembly 22 spaced apart along the X-axis direction, and a plurality of guide rollers 23 staggered between the discharge assembly 21 and the receiving assembly 22. The discharge assembly 21 is used to supply the film 200, and the receiving assembly 22 is used to collect the film 200. The plurality of guide rollers 23 are used to guide the movement of the film 200 between the discharge assembly 21 and the receiving assembly 22. The discharge assembly 21 and the receiving assembly 22 can both be a structure in which a rotating motor drives a rotating shaft. The guide rollers 23 extend along the Y-axis direction and can rotate around the Y-axis direction. The number of guide rollers 23 can be two, three, four, etc., so as to change the movement direction of the film 200 between the discharge assembly 21 and the receiving assembly 22. The specific number and position are subject to actual needs and are not limited here. It can be understood that the rolled new film 200 is installed on the unloading assembly 21, and then the film 200 passes through multiple guide rollers 23 and is then connected to the receiving assembly 22. During use, the unloading assembly 21 and the receiving assembly 22 move synchronously to unload and receive the film, thereby moving the film 200 from the unloading assembly 21 to the receiving assembly 22.

[0031] The film laminating mechanism 30 is connected to the frame 10 and is disposed between the unwinding assembly 21 and the receiving assembly 22. The film laminating mechanism 30 includes a nip roller 31, which abuts against the film 200. The nip roller 31 extends along the Y-axis and can rotate about the Y-axis. It can be understood that the nip roller 31 abuts against the back surface of the film 200, that is, the adhesive surface of the film 200 faces away from the nip roller 31.

[0032] The material moving mechanism 40 is arranged on the frame 10, including a material moving component 41 arranged below the material unloading component 21 and the film laminating mechanism 30, and a positioning component 42 connected to the material moving component 41. The positioning component 42 is used to carry and position the workpiece 300. The material moving component 41 is used to drive the positioning component 42 and the workpiece 300 to move to the bottom of the film laminating mechanism 30, and during the movement, the workpiece 300 is abutted against the film part 200 supported by the pressing roller 31, and then the film part 200 is laminated to the workpiece 300 under the rolling pressure of the pressing roller 31.

[0033] The film cutting mechanism 50 is disposed on the frame 10 and mounted above the film laminating mechanism 30. The film cutting mechanism 50 is used to cut the film 200 attached to the workpiece 300. The film cutting mechanism 50 can be a laser film cutting machine, etc. When the material transfer mechanism 40 cooperates with the pressure roller 31 to attach the film 200 to the workpiece 300 and moves the workpiece 300 below the film cutting mechanism 50, the film cutting mechanism 50 cuts the film 200 to cut off the film 200 that is adapted to the size of the position on the workpiece 300 to be laminating, and then retains the required film 200 on the workpiece 300. The excess film 200 is collected by the receiving assembly 22.

[0034] In this embodiment, after the film cutting mechanism 50 cuts the film 200 on the workpiece 300 , the material moving mechanism 40 drives the workpiece 300 to move from under the film cutting mechanism 50 to under the unloading assembly 21 to facilitate the removal of the workpiece 300 .

[0035] The film laminating device 100 provided in the embodiment of the present application provides film 200 via the unloading assembly 21 in the film supply mechanism 20, collects discarded film 200 via the receiving assembly 22, guides the film 200 between the unloading assembly 21 and the receiving assembly 22 via the guide roller 23, and carries and positions the workpiece 300 via the material transfer mechanism 40, which moves the workpiece 300 toward the film laminating mechanism 30. During movement, the workpiece 300 abuts against the film 200 held by the pressure roller 31 of the film laminating mechanism 30, and then cooperates with the pressure roller 31 to adhere the film 200 to the workpiece 300 during the movement. The material transfer mechanism 40 moves the workpiece 300 to the bottom of the film cutting mechanism 50, which cuts the film 200 on the workpiece 300 to retain the required film 200 on the workpiece 300, and the excess film 200 is taken away by the receiving assembly 22. The film pasting device 100 provided in the embodiment of the present application can automatically paste the film and automatically cut the film 200, thereby achieving high production efficiency.

[0036] In some embodiments, see Figure 1 、 Figure 2 and Figure 3 The material moving assembly 41 includes a material moving drive 411 and a material moving frame 412. The material moving drive 411 is connected to the frame 10 and is disposed below the material unwinding assembly 21 and the film laminating mechanism 30. The material moving frame 412 is connected to the material moving drive 411. The material moving drive 411 is used to drive the material moving frame 412 to move along the X-axis direction below the material unwinding assembly 21 and the film cutting mechanism 50. The material moving drive 411 can be a cylinder, a linear module, etc., and the material moving frame 412 can be a mechanism composed of a plurality of support columns and a support panel.

[0037] The material moving mechanism 40 further includes a height adjustment assembly 43, which is connected to the material moving frame 412. The positioning assembly 42 is slidably connected to the material moving frame 412 along the Z-axis direction, and the positioning assembly 42 is also connected to the output end of the height adjustment assembly 43. The height adjustment assembly 43 is used to drive the positioning assembly 42 to move along the Z-axis direction to adjust the position of the workpiece 300 in the Z-axis direction.

[0038] When the material transfer rack 412 is located below the discharge assembly 21, the height adjustment assembly 43 drives the positioning assembly 42 to move upward along the Z-axis direction so that the upper surface of the workpiece 300 located on the positioning assembly 42 and the lower end cross-section of the pressure roller 31 are located on the same horizontal plane, and then the material transfer drive 411 drives the material transfer rack 412 to move toward the film cutting mechanism 50, and the film is applied when the workpiece 300 passes through the pressure roller 31. After the film cutting mechanism 50 cuts the film of the workpiece 300 below it, the height adjustment component 43 drives the positioning component 42 to move downward in the opposite direction of the Z-axis direction, so that the film part 200 on the workpiece 300 is separated from other discarded film parts 200, and the upper surface of the workpiece 300 is lower than the pressing roller 31 in the Z-axis direction. Then the material moving drive component 411 drives the material moving rack 412 to move downward of the discharge component 21. The workpiece 300 does not contact the pressing roller 31 when passing through the pressing roller 31, which can prevent the film part 200 supported by the pressing roller 31 from contacting the film part 200 attached to the workpiece 300, thereby preventing the film part 200 from falling off the workpiece 300.

[0039] In some embodiments, see Figure 2 、 Figure 3 and Figure 4The height adjustment assembly 43 includes an adjustment drive 431 and an adjustment member 432. The adjustment drive 431 is connected to the material moving rack 412, and the adjustment member 432 is connected to the adjustment drive 431. The adjustment member 432 is provided with a sliding hole 4321. The sliding hole 4321 is tilted, and the two ends of the sliding hole 4321 have a height difference in the Z-axis direction. One end of the positioning assembly 42 connected to the height adjustment assembly 43 is movably inserted into the sliding hole 4321. The adjustment drive 431 is used to drive the adjustment member 432 to move along the X-axis direction and then guide the positioning assembly 42 to move in the Z-axis direction through the sliding hole 4321 to adjust the position of the workpiece 300 in the Z-axis direction. The adjustment drive 431 can be a driver such as a cylinder, the adjustment member 432 can be a plate-like structure, and the sliding hole 4321 can be a bar-shaped hole, etc. It can be understood that one end of the sliding hole 4321 is higher than the other end. The adjusting drive member 431 drives the adjusting member 432 to move in the X-axis direction, and then guides the positioning component 42 to move in the Z-axis direction through the sliding hole 4321. When the positioning component 42 is opposite to the higher end of the sliding hole 4321, the workpiece 300 on the positioning component 42 corresponds to the pressing roller 31. When the positioning component 42 is opposite to the lower end of the sliding hole 4321, the workpiece 300 on the positioning component 42 is lower than the pressing roller 31.

[0040] In some embodiments, see Figure 2 、 Figure 3 and Figure 4 The positioning assembly 42 includes a carrier 421, a rotary drive member 422, and a positioning member 423. The carrier 421 is slidably connected to the material moving frame 412 along the Z-axis direction. A rolling member 4211 is provided at one end of the carrier 421 close to the adjustment member 432. The rolling member 4211 is movably inserted into the sliding hole 4321 to enable the carrier 421 to be movably connected to the adjustment member 432. The rotary drive member 422 is connected to the end of the carrier 421 away from the adjustment member 432. The positioning member 423 is connected to the rotary drive member 422. The positioning member 423 is used to carry the workpiece 300. The rotary drive member 422 is used to drive the positioning member 423 and the workpiece 300 to rotate about the Y-axis direction. A structure such as a slide rail can be provided between the carrier 421 and the material moving frame 412 to improve the stability of the sliding connection between the carrier 421 and the material moving frame 412. The rolling element 4211 can be a bearing, roller, or the like. The provision of the rolling element 4211 improves the smoothness of the movement of the support frame 421 driven by the adjustment element 432. The rotating drive element 422 can be a rotary cylinder, rotary motor, or the like, and is used to rotate the positioning element 423. The positioning element 423 is structurally compatible with the workpiece 300 and is used to internally support the workpiece 300.

[0041] It is understood that the workpiece 300 may have multiple surfaces that require film application, such as two, three, or four surfaces. In this embodiment, all four sides of the workpiece 300 require film application. When the material shifting assembly 41 causes the workpiece 300 to move toward the press roller 31, the press roller 31 can apply film application to one of the sides of the workpiece 300. The film 200 is then cut by the film cutting mechanism 50, and the workpiece 300 is moved to the bottom of the unloading assembly 21 by the material shifting assembly 41. When another side of the workpiece 300 needs to be film applied, the positioning member 423 is rotated by the rotating drive member 422, thereby driving the workpiece 300 to rotate, and the side to be film applied is rotated upward. Repeating the above steps can apply film application to multiple sides of the workpiece 300.

[0042] In some embodiments, see Figure 3 and Figure 4 The positioning member 423 is provided with a vacuum suction cup 4231, which is used to absorb the workpiece 300. By providing the vacuum suction cup 4231, the stability of positioning the workpiece 300 can be improved, thereby improving the accuracy of film application.

[0043] In some embodiments, see Figure 2 and Figure 5 The film laminating mechanism 30 includes two nip rollers 31 , spaced apart along the X-axis between the unwinding assembly 21 and the receiving assembly 22 . The two nip rollers 31 are positioned at the same height along the Z-axis. It will be appreciated that the two nip rollers 31 are positioned within the XY plane, allowing the film 200 positioned between the two nip rollers 31 to lie within the XY plane. This allows the film 200 positioned between the two nip rollers 31 to remain flush with the film laminating side of the workpiece 300 as it moves toward the film cutting mechanism 50 , preventing the film 200 from falling off the workpiece 300.

[0044] In some embodiments, see Figure 1 、 Figure 2 and Figure 5The film laminating mechanism 30 further includes a support base 32 connected to the frame 10, and a nip roller 31 is adjustably connected to the support base 32. The support base 32 may include a plurality of plate-like structures, and both ends of the nip roller 31 are connected to the support base 32. The support base 32 may be provided with a strip hole, and the nip roller 31 is connected to the strip hole. By adjusting the connection position between the nip roller 31 and the strip hole, the height of the nip roller 31 can be adjusted. It can be understood that different types of workpieces 300 have different sizes. When the size of the workpiece 300 is large, after the workpiece 300 is mounted on the positioning assembly 42, the height of the upper side surface to be laminating the film will be higher than the lower cross-section of the nip roller 31. At this time, by adjusting the position of the nip roller 31 in the Z-axis direction so that the lower cross-section of the nip roller 31 corresponds to the upper side surface of the workpiece 300, the film laminating can be performed. When the size of the workpiece 300 is small, after the workpiece 300 is installed on the positioning assembly 42, the height of the upper side surface to be laminated will be lower than the lower cross-section of the pressing roller 31. At this time, by adjusting the position of the pressing roller 31 in the Z-axis direction so that the lower cross-section of the pressing roller 31 corresponds to the upper side surface of the workpiece 300, the film can be laminated.

[0045] In some embodiments, see Figure 2 、 Figure 3 and Figure 5 The workpiece 300 has a curved surface 301. The workpiece 300 can be a rounded rectangle with four curved corners. When applying the film, the curved surface 301 needs to be rolled and pasted.

[0046] The film laminating mechanism 30 further includes a rolling assembly 33 , which includes a horizontal driving member 331 , a support frame 332 , a vertical driving member 333 and a rolling member 334 .

[0047] The horizontal driving member 331 is connected to the support base 32. The support frame 332 is slidably connected to the support base 32 along the X-axis direction and is drivingly connected to the horizontal driving member 331. The vertical driving member 333 is connected to the support frame 332, and the rolling member 334 is connected to the vertical driving member 333. The horizontal driving member 331 is used to drive the support frame 332 to move along the X-axis direction, thereby driving the vertical driving member 333 and the rolling member 334 to move along the X-axis direction. The vertical driving member 333 is used to drive the rolling member 334 to move along the Z-axis direction. The horizontal driving member 331 and the vertical driving member 333 cooperate with each other to cause the rolling member 334 to perform an arc-shaped motion in a plane perpendicular to the Y-axis direction. After the film cutting mechanism 50 cuts the film 200 bonded to the workpiece 300, the rolling member 334 rolls and bonds the film 200 corresponding to the curved surface 301. The horizontal driving member 331 can be a driver such as a cylinder, the support frame 332 can be connected to the support seat 32 through a slide rail, etc. to improve the stability of the movement of the support frame 332, the vertical driving member 333 can be a cylinder, etc., the rolling member 334 can be a roller, etc., and the width of the rolling member 334 along the Y-axis direction is adapted to the width of the workpiece 300.

[0048] The rolling assembly 33 operates as follows: after the material transfer assembly 41 moves the workpiece 300 below the film cutting mechanism 50, the film 200 is adhered to the upper side of the workpiece 300. The film cutting mechanism 50 then cuts the film 200, cutting off the film 200 opposite the curved surface 301 of the workpiece 300. At this point, the film 200 opposite the curved surface 301 is not yet adhered to the curved surface 301. The horizontal drive member 331 in the rolling assembly 33 then drives the support frame 332 to move, which in turn drives the vertical drive member 333 to move, which in turn drives the rolling member 334 to move until the rolling member 334 contacts the film 200 on the workpiece 300. At this time, the rolling member 334 is opposite to the connection between the plane and the curved surface 301 of the workpiece 300, and then the horizontal driving member 331 drives the support frame 332 to move away from the workpiece 300, and the vertical driving member 333 drives the rolling member 334 to move downward. In this way, the rolling member 334 can be pressed against the curved surface 301 and move in an arc, thereby sticking the film member 200 to the curved surface 301.

[0049] In this embodiment, two groups of rolling assemblies 33 are symmetrically arranged to apply film to the two curved surfaces 301 of the workpiece 300 .

[0050] In some embodiments, see Figure 5 and Figure 6 The film-laminating mechanism 30 further includes an elastic component 34 , which includes a support frame 341 , a sliding block 342 , a first elastic member 343 , a movable member 344 and a second elastic member 345 .

[0051] The support frame 341 is connected to the vertical driving member 333 and has a movable through hole 3411 extending along the Z-axis through the support frame 341. The support frame 341 may be in a square shape and the movable through hole 3411 may be a square hole.

[0052] The sliding block 342 is arranged in the movable through hole 3411 and is slidably connected to the support frame 341 along the X-axis direction. A sliding rod (not shown) can be provided in the support frame 341, and the sliding block 342 is sleeved on the sliding rod to improve the stability of the sliding block 342 when sliding.

[0053] The first elastic member 343 is disposed within the movable through-hole 3411. Its two ends respectively abut the sliding block 342 and the side wall of the movable through-hole 3411 near the vertical driving member 333. The first elastic member 343 is used to push the sliding block 342 away from the vertical driving member 333. The first elastic member 343 can be an elastic device such as a spring. To improve the stability of the first elastic member 343, the first elastic member 343 can be mounted on the slide rod.

[0054] The movable member 344 includes a movable portion 3441 slidably connected to the sliding block 342 along the Z-axis direction and a connecting portion 3442 provided at the lower end of the movable portion 3441. The rolling member 334 is connected to the connecting portion 3442. The movable portion 3441 may be a rod-shaped structure, and the connecting portion 3442 may be a U-shaped structure.

[0055] The second elastic member 345 is disposed between the connecting portion 3442 and the sliding block 342. The second elastic member 345 has two ends that abut the connecting portion 3442 and the sliding block 342, respectively. The second elastic member 345 is used to push the connecting portion 3442 away from the sliding block 342. The second elastic member 345 may be a spring or the like. To improve the stability of the second elastic member 345, the second elastic member 345 may be sleeved over the connecting portion 3442.

[0056] It is understood that in order to ensure that the film member 200 can be tightly attached to the workpiece 300, it is necessary to increase the pressure on the rolling member 334. By providing the elastic component 34, it is possible to prevent the rolling member 334 from exerting excessive pressure on the workpiece 300, thereby preventing damage to the workpiece 300. When the rolling member 334 rolls the film member 200, the movable member 344 can elastically contact the workpiece 300 along the Z-axis under the action of the second elastic member 345. The movable member 344 also elastically contacts the workpiece 300 along the X-axis under the action of the sliding block 342 and the first elastic member 343. This ensures that the rolling member 334 always maintains elastic contact with the workpiece 300 when rolling the curved surface 301, effectively preventing the rolling member 334 from damaging the workpiece 300.

[0057] In some embodiments, see Figure 1 and Figure 2The film feeding mechanism 20 further includes a traction assembly 24, which includes a traction drive 241 and a traction roller 242. The traction drive 241 is connected to the frame 10 and disposed between the unwinding assembly 21 and the receiving assembly 22. The traction roller 242 is connected to the traction drive 241 and disposed between two adjacent guide rollers 23. The traction drive 241 is configured to drive the traction roller 242 to move along the Z-axis, so that the traction roller 242 pushes against the film 200, thereby pulling the film 200 in motion. The traction drive 241 can be a drive device such as a linear module. The traction roller 242 extends along the Y-axis and can rotate about the Y-axis.

[0058] It is understood that the film 200 is usually installed in a roll on the unwinding assembly 21, and the rewinding assembly 22 is also rewinding in a roll. As the film 200 is used, the radius of the film rolls of the unwinding assembly 21 and the rewinding assembly 22 are different. This causes the unwinding speed of the unwinding assembly 21 and the rewinding speed of the rewinding assembly 22 to be inconsistent at the same rotation speed, which can easily cause the film 200 located in the middle to be uneven. In order to solve this problem, the present embodiment is provided with a traction assembly 24. When the unwinding assembly 21 unwinds, the rewinding assembly 22 stops running, and the traction drive member 241 drives the traction roller 242 to move downward, thereby traction-driving the film 200 to move, so that the new film 200 moves to the nip roller 31, and moves synchronously with the unwinding assembly 21 when film is applied, so as to facilitate film application on the workpiece 300. When the receiving assembly 22 is receiving the film, the unloading assembly 21 stops, the receiving assembly 22 starts receiving the film, and the traction drive 241 drives the traction roller 242 upward so that the film 200 is collected by the receiving assembly 22. This effectively solves the problem of uneven film 200 caused by the difference in the unloading speed of the unloading assembly 21 and the collecting speed of the receiving assembly 22.

[0059] The working process of the film laminating device 100 provided in the embodiment of the present application is roughly as follows:

[0060] First, see Figure 1 and Figure 2 , install the workpiece 300 on the positioning assembly 42, and make the side to be film-coated be located at the top, then the material moving assembly 41 moves the workpiece 300 toward the film cutting mechanism 50, see Figure 7 When the workpiece 300 passes through the pressing roller 31 of the film laminating mechanism 30, the pressing roller 31 presses the film 200 to the workpiece 300 so that the film 200 is attached to the workpiece 300. The material moving component 41 moves the workpiece 300 to the bottom of the film cutting mechanism 50 and then stops moving.

[0061] Then the film cutting mechanism 50 cuts the film 200 and reserves the film 200 on the curved surface 301 of the workpiece 300. Figure 8After the cutting is completed, the rolling assembly 33 starts to operate, and with the cooperation of the horizontal driving member 331 and the vertical driving member 333, it drives the rolling member 334 to make an arc movement along the arc surface 301, and then the film member 200 corresponding to the arc surface 301 is attached to the arc surface 301. After the attachment is completed, the rolling assembly 33 is reset.

[0062] After the film part 200 is pasted, the height adjustment component 43 drives the positioning component 42 and the workpiece 300 to move downward to avoid the pressure roller 31, and then the material moving component 41 moves the positioning component 42 and the workpiece 300 to the bottom of the discharge component 21, and the rotary drive component 422 drives the positioning component 423 to rotate, thereby driving the workpiece 300 to rotate, so as to rotate the next film-pasting surface of the workpiece 300 to the top, and at the same time, the height adjustment component 43 drives the positioning component 42 and the workpiece 300 to move upward so that the film-pasting surface of the workpiece 300 corresponds to the pressure roller 31, and the above film-pasting steps are repeated.
