Description

Technical Field

[0001] The present application relates to the field of product packaging, and in particular to a film-sticking device. Background Art

[0002] Product packaging can be seen everywhere in industrial production. For example, in the electronics industry, the surface of the product is usually the entire exterior surface, and the product surface needs to be fully packaged and protected to avoid scratches caused by human operation or contact between products.

[0003] In the prior art, product packaging, such as using a protective film on the surface of the product, requires that the protective film be adhered to both the front and back surfaces of the product. This can easily lead to problems with the films on both sides of the product being poorly adhered, such as wrinkles on the film when it is adhered to the product surface or the film not being completely adhered to the product surface. Summary of the Invention

[0004] The present application provides a film laminating device to solve the problem that the existing product packaging films on both the front and back sides are prone to poor film lamination.

[0005] An embodiment of the present application provides a film-applying device for attaching a film assembly to a product, wherein the product has a first surface and a second surface facing each other, and the film assembly has a first film segment and a second film segment connected to each other. The film-applying device includes a carrier, a film pressing assembly, and a clamping assembly. The carrier has a bearing surface for sequentially supporting the first film segment and the product, and causing the first film segment to adhere to the first surface of the product. The film pressing assembly is used to press against the film assembly and define a rotation axis for the second film segment to flip relative to the first film segment. The clamping assembly is used to clamp the film assembly and drive the second film segment to flip relative to the first film segment around the rotation axis to adhere to the second surface of the product.

[0006] Compared with the prior art, the film-laminating device provided in the embodiment of the present application first bonds the first film segment of the film assembly to the first surface of the product through a supporting member, and then the film pressing assembly cooperates with the supporting surface and presses between the first film segment and the second film segment, and the clamping assembly cooperates with the film pressing assembly and drives the second film segment to flip around the rotation axis relative to the first film segment to bond to the second surface of the product, thereby realizing the flipping of the film assembly to bond to the product, so as to achieve the effect of improving the position accuracy of the film assembly bonding to the front and back surfaces of the product.

[0007] In one possible embodiment, the first membrane segment and the second membrane segment are connected along the length of the membrane assembly. Two membrane pressing assemblies are provided, one on each side of the membrane assembly in the width direction. The membrane pressing assembly includes a pressure rod, each of which presses against each side of the membrane assembly in the width direction. The two pressure rods are collinearly arranged along the width direction of the membrane assembly to define the rotation axis.

[0008] Furthermore, two film pressing assemblies are provided, and two pressure rods are arranged collinearly along the width direction of the film assembly to define the rotation axis, which is conducive to the flipping operation of the second film segment. The pressure rods and the clamping assembly work together to make the first film segment and the second film segment fit the front and back sides of the product together.

[0009] In one possible embodiment, the second surface is high in the middle and low on both sides in the width direction of the membrane assembly. The two pressing assemblies can be pressed against both sides of the membrane assembly in the width direction, so that the second membrane segment is stretched by the clamping assembly on both sides in the width direction to fit around the second surface.

[0010] Furthermore, the pressure rod cooperates with the second surface in the width direction of the membrane assembly, and the pressure rod presses the membrane assembly so that the membrane assembly is attached to the second surface in the width direction, which is conducive to the second membrane segment being flatly attached to the second surface in the width direction.

[0011] In a possible embodiment, the membrane pressing assembly includes a driving member, which is transmission-connected to the pressure rod, and the driving member is used to drive the pressure rod to move to a first position or a second position, the first position being the position where the pressure rod presses against the membrane assembly, and the second position being the position where the pressure rod is away from the membrane assembly.

[0012] In a possible embodiment, the carrying surface is provided with vacuum vents for absorbing the first film segment carried on the carrying surface so that the first film segment is attached to the first surface of the product.

[0013] In one possible embodiment, along the length of the membrane assembly, the first surface is a curved surface that is higher in the middle and lower around the periphery. The film-applying device further includes a first plate and a second plate. The first plate, the second plate, and the support member are arranged along the length of the membrane assembly. The first plate and the second plate are arranged on both sides of the support member, and the height of the first plate and the second plate is lower than the support surface. The film-applying device further includes a material rack. The membrane assembly is movably mounted on the material rack. The material rack is used to limit the rotation of the membrane assembly around an axis. The membrane assembly can rotate around the axis on the material rack and extend toward the first plate, and then continue to extend toward the support member and the second plate through the surface of the first plate.

[0014] In a possible implementation manner, a side of the second plate member close to the adsorption member is concave to form a groove, and the film pressing assembly can press the film assembly into the groove.

[0015] Furthermore, the second plate is provided with a groove. After the first membrane segment of the membrane assembly is attached to the support surface, the film pressing assembly facilitates pressing the end of the first membrane segment into the groove, thereby pulling the first membrane segment flat on the support surface. Simultaneously, when the moving assembly pulls the second membrane segment from the second plate to the second surface, the film pressing assembly presses the end of the second membrane segment into the groove, causing the second membrane segment to adhere to the second surface from a lower height toward a higher height. Therefore, the provision of the groove facilitates the film pressing assembly in attaching the membrane assembly to both the front and back sides of the product.

[0016] In a possible embodiment, the clamping assembly includes a first clamping member and a second clamping member, wherein the first clamping member and the second clamping member are opposite to each other and are arranged on both sides of the membrane assembly in a width direction.

[0017] In one possible embodiment, the first clamping member includes a first clamping head and a second clamping head, the first clamping head and the second clamping head are spaced apart along the length direction of the membrane assembly, and the first clamping head and the second clamping head are used to clamp one side edge of the second membrane segment in the width direction. The second clamping member includes a third clamping head and a fourth clamping head, the third clamping head and the fourth clamping head are spaced apart along the length direction of the membrane assembly, and the third clamping head and the fourth clamping head are used to clamp the other side edge of the second membrane segment in the width direction, and the first clamping head and the third clamping head correspond to each other along the width direction of the membrane assembly, and the second clamping head and the fourth clamping head correspond to each other along the width direction of the membrane assembly. The film-applying device also includes a cutter for cutting the membrane assembly between the clamping position of the first clamping head and the third clamping head and the clamping position of the second clamping head and the fourth clamping head.

[0018] After the membrane assembly is cut, the second and fourth clamping heads release the membrane assembly, completing the product film application and removing the product from the carrier. The first and third clamping heads clamp the membrane assembly and pull it to the second plate for the next product to be filmed.

[0019] In a possible implementation manner, the film-applying device further includes a moving component, the moving component is transmission-connected to the clamping component, and the moving component is used to drive the clamping component to move. BRIEF DESCRIPTION OF THE DRAWINGS

The term "or / and" as used herein includes any and all combinations of one or more of the relevant listed items.

[0070] The following describes some embodiments of the present application in detail. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0071] See also Figures 1 to 6 , an embodiment of the present application provides a film-applying device 1 for attaching a film assembly 2 to a product 3, wherein the product 3 has a first surface 31 and a second surface 32 relative to each other. The membrane assembly 2 has a first membrane segment 21 and a second membrane segment 22 connected to each other, and the film-applying device 1 includes a carrier 11, a film pressing assembly 12, and a clamping assembly 13. The carrier 11 has a carrying surface 111, which is used to carry the first membrane segment 21 and the product 3 in sequence, and to make the first membrane segment 21 adhere to the first surface 31 of the product 3. The film pressing assembly 12 is used to press against the membrane assembly 2 and define a rotation axis 121 for the second membrane segment 22 to flip relative to the first membrane segment 21. The clamping assembly 13 is used to clamp the membrane assembly 2 and drive the second membrane segment 22 to flip relative to the first membrane segment 21 around the rotation axis 121 to adhere to the second surface 32 of the product 3.

[0072] The film-laminating device 1 provided in this embodiment first laminates the first film segment 21 of the film assembly 2 and the first surface 31 of the product 3 through the supporting member 11, and then the film pressing assembly 12 cooperates with the supporting surface 111 and presses between the first film segment 21 and the second film segment 22. The clamping assembly 13 cooperates with the film pressing assembly 12 and drives the second film segment 22 to flip relative to the first film segment 21 around the rotation axis 121 to fit the second surface 32 of the product 3, thereby realizing the flipping and laminating of the film assembly 2 to the product 3, so as to improve the position accuracy of the film assembly 2 laminating the front and back surfaces of the product 3.

[0073] Please combine Figure 2 and Figure 3As shown, the membrane assembly 2 is elastic and can be stretched and deformed. The membrane assembly 2 can be a plastic film.

[0074] Product 3 is an appearance part, such as a mouse case, a mobile phone case or a computer case, etc., but this application is not limited to this.

[0075] The first surface 31 is the back side of the product 3, and the second surface 32 is the front side of the product 3. The first surface 31 and the second surface 32 constitute the front and back sides of the product 3. The membrane assembly 2 is attached to the first surface 31 and the second surface 32 of the product 3.

[0076] In one embodiment, the first membrane segment 21 and the second membrane segment 22 are connected along the length direction 23 of the membrane assembly 2. Two membrane pressing assemblies 12 are provided, one on each side of the width direction 24 of the membrane assembly 2. The membrane pressing assemblies 12 include pressure rods 122, which press against the two sides of the width direction 24 of the membrane assembly 2. The two pressure rods 122 are collinearly arranged along the width direction 24 of the membrane assembly 2 to define a rotation axis 121.

[0077] In this embodiment, the pressure rods 122 are cylindrical, slender rods, and the two pressure rods 122 extend in a straight line. The heads of the pressure rods 122 are spherical or arc-shaped to prevent sharp corners on the pressure rods 122 from scratching the membrane assembly 2. The circumferential surfaces of the pressure rods 122 press between the first membrane segment 21 and the second membrane segment 22. When the clamping assembly 13 clamps the membrane assembly 2 and moves, the two pressure rods 122 define the rotation axis 121 of the membrane assembly 2. The pressure rods 122 and the clamping assembly 13 work together to flip the second membrane segment 22 180° to fit the second surface 32 of the product 3.

[0078] Two film pressing assemblies 12 are provided, and two pressing rods 122 are arranged colinearly along the width direction 24 of the film assembly 2 to define the rotation axis 121, which is conducive to the flipping operation of the second film segment 22 in the length direction 23. The pressing rods 122 and the clamping assembly 13 work together to make the first film segment 21 and the second film segment 22 fit together on the front and back sides of the product 3.

[0079] In one embodiment, the second surface 32 is higher in the middle and lower on both sides of the membrane assembly 2 in the width direction 24. The two pressing assemblies 12 can be pressed against both sides of the membrane assembly 2 in the width direction 24, causing the second membrane segment 22 to be stretched along both sides of the width direction 24 by the clamping assemblies 13 to conform to the periphery of the second surface 32.

[0080] Please combine Figures 4 to 6As shown, specifically, the membrane assembly 2 is elastic, and the second surface 32 of the product 3 is a curved surface. After the second membrane segment 22 rotates circumferentially around the two pressure rods 122, the membrane assembly 2 is wrapped around the ends of the two pressure rods 122. At this time, the downward pressure of the pressure rods 122 causes the membrane assembly 2 to bend and stretch both sides in the width direction 24. The pressure rods 122 engage with the second surface 32 in the width direction 24 of the membrane assembly 2. The pressure rods 122 press the membrane assembly 2 together, causing the membrane assembly 2 to adhere to the second surface 32 in the width direction 24. This facilitates smooth adhesion of the second membrane segment 22 to the second surface 32 in the width direction 24.

[0081] In one embodiment, the membrane pressing assembly 12 includes a driving member 123, which is in transmission connection with the pressure rod 122. The driving member 123 is used to drive the pressure rod 122 to move to a first position 124 or a second position 125. The first position 124 is the position where the pressure rod 122 presses against the membrane assembly 2, and the second position 125 is the position where the pressure rod 122 is away from the membrane assembly 2.

[0082] Optionally, the driving member 123 includes a first cylinder 126 and a second cylinder 127. The first cylinder 126 is movably disposed along a first direction and is in transmission connection with the second cylinder 127. The second cylinder 127 is movably disposed along a second direction and is in transmission connection with the pressure rod 122. The first direction is the direction in which the pressure rod 122 presses against and releases the membrane assembly 2, and the second direction is the width direction 24 of the membrane assembly 2. The first direction is perpendicular or inclined to the second direction. The driving member 123 drives the pressure rod 122 to move via the first cylinder 126 and the second cylinder 127, thereby moving the pressure rod 122 between a first position 124 and a second position 125.

[0083] In one embodiment, the supporting surface 111 defines vacuum holes 112 for adsorbing the first film segment 21 supported on the supporting surface 111 so that the first film segment 21 is adhered to the first surface 31 of the product 3 .

[0084] Please combine Figure 6As shown, in this embodiment, the carrier 11 is connected to a negative pressure air source (not shown). The interior of the carrier 11 defines a hollow cavity 113. Air holes 112 communicate with the cavity 113. The negative pressure air source evacuates the cavity 113, causing the air holes 112 to absorb the first membrane segment 21. Before evacuation, the first membrane segment 21 is placed on the carrier surface 111. Due to the shape and strength of the membrane assembly 2, the first membrane segment 21 does not conform to the carrier surface 111. If a product 3 is placed on the carrier 11 at this point, the product 3 may wrinkle the first membrane segment 21. First, the first membrane segment 21 of the membrane assembly 2 is pulled to the supporting surface 111 by the clamping assembly 13, and the clamping assembly 13 flattens the first membrane segment 21. Then, vacuum is drawn through the air holes 112 of the supporting part 11 to make the first membrane segment 21 adsorbed on the supporting surface 111, so that the first membrane segment 21 and the supporting surface 111 fit flatly. Finally, the first surface 31 of the product 3 is placed on the supporting part 11 corresponding to the first membrane segment 21. This operation is conducive to the first membrane segment 21 and the first surface 31 of the product 3 fitting flatly.

[0085] The diameter of the pores 112 ranges from 0.5 mm to 1 mm to prevent the pores 112 from being too large and sucking the membrane assembly 2 into the cavity 113, or the pores 112 from being too small and resulting in insufficient adsorption force. The pores 112 are evenly distributed on the supporting surface 111. This arrangement is conducive to the supporting surface 111 adsorbing the membrane assembly 2.

[0086] In one embodiment, please combine Figure 5 As shown, along the length direction 23 of the membrane assembly 2, the first surface 31 is a curved surface that is higher in the middle and lower around the periphery. The film laminating device 1 also includes a first plate 14 and a second plate 15. The first plate 14, the second plate 15, and the support member 11 are arranged along the length direction 23 of the membrane assembly 2. The first plate 14 and the second plate 15 are arranged on both sides of the support member 11. The height of the first plate 14 and the second plate 15 is lower than the support surface 111. The film laminating device 1 also includes a material rack 16. The membrane assembly 2 is movably mounted on the material rack 16. The material rack 16 is used to limit the rotation of the membrane assembly 2 around an axis. The membrane assembly 2 can rotate around the axis on the material rack 16 and extend toward the first plate 14, and continue to extend toward the support member 11 and the second plate 15 through the surface of the first plate 14.

[0087] In this embodiment, the film laminating device 1 further includes a base 19, which can be made of a metal frame. The first plate 14, the second plate 15, the carrier 11, the film pressing assembly 12, and the material rack 16 are fixed to the base 19. The base 19 is used to support and fix the various components to maintain their positional accuracy.

[0088] The first plate 14 and the second plate 15 are flat plates, which extend along the length direction 23 of the membrane assembly 2 and are used to lay the membrane assembly 2 flatly on the surfaces of the first plate 14 and the second plate 15 .

[0089] The membrane assembly 2 is placed on a rack 16, which is movably connected to the membrane assembly 2. The rack 16 and the first plate 14 are spaced apart. The height of the loading end of the membrane assembly 2 is lower than the surface height of the first plate 14. The loading end of the membrane assembly 2 moves from the bottom of the rack 16 toward the surface of the first plate 14. The rack 16 and the first plate 14 can tighten and flatten the membrane assembly 2, so that the membrane assembly 2 is laid flat on the first plate 14.

[0090] The moving assembly 18 clamps the loading end of the membrane assembly 2 and moves it from the first plate 14 to the second plate 15. The membrane assembly 2 is pulled by the moving assembly 18 and loaded from the first plate 14. The first membrane segment 21 is laid on the support surface 111, and the second membrane segment 22 is laid on the second plate 15. The film pressing assembly 12 is then pressed between the first membrane segment 21 and the second membrane segment 22. The film pressing assembly 12 and the support 11 cooperate to press the first membrane segment 21 against the support surface 111 for vacuum adsorption. The first surface 31 of the product 3 is placed on the support 11 in correspondence with the first membrane segment 21. The moving assembly 18 then moves from the second plate 15 to between the support 11 and the first plate 14. The moving assembly 18 then pulls the second membrane segment 22 around the film pressing assembly 12 to rotate to the corresponding second surface 32 of the product 3, allowing the film pressing assembly 12 to press the second membrane segment 22 onto the second surface 32.

[0091] In one embodiment, a side of the second plate 15 close to the adsorption element is concave to form a groove 151 , and the membrane pressing assembly 12 can press the membrane assembly 2 into the groove 151 .

[0092] Optionally, combine Figure 5 As shown, viewed from the length direction 23, the second plate 15 is provided with a groove 151. After the first membrane segment 21 of the membrane assembly 2 is attached to the support surface 111, the pressing assembly 12 facilitates pressing the end of the first membrane segment 21 into the groove 151, causing the first membrane segment 21 to be pulled flat and thus evenly attached to the support surface 111 to adapt to the shape of the first surface 31. This facilitates the adhesion of the first membrane segment 21 to the first surface 31 and reduces wrinkles in the first membrane segment 21 after being attached to the product 3. Simultaneously, when the moving assembly 18 pulls the second membrane segment 22 from the second plate 15 to the second surface 32, the pressing assembly 12 presses the end of the second membrane segment 22 into the groove 151, causing the second membrane segment 22 to adhere to the second surface 32 from a lower height portion toward a higher height portion. If the film pressing assembly 12 does not press the end of the second film segment 22 into the groove 151, the height of the end of the second film segment 22 is higher than the height of the second surface 32, and the edge position located below the second surface 32 is likely to cause the second film segment 22 to not fit the second surface 32.

[0093] Please combine Figure 6As shown, from the width direction 24, the two pressing rods 122 press the membrane assembly 2 into the groove 151 on both sides along the width direction 24. This facilitates the first membrane segment 21 to bend in the width direction 24 and better fit the support surface 111, so that the first membrane segment 21 is more closely attached to the first surface 31. At the same time, the second membrane segment 22 is bent in the width direction 24 and more closely attached to the second surface 32. Therefore, the provision of the groove 151 facilitates the membrane pressing assembly 12 to attach the membrane assembly 2 to both the front and back surfaces of the product 3.

[0094] In one embodiment, the clamping assembly 13 includes a first clamping member 131 and a second clamping member 132 . The first clamping member 131 and the second clamping member 132 are opposite to each other and are disposed on two sides of the membrane assembly 2 in the width direction 24 .

[0095] In this embodiment, the first clamping member 131 and the second clamping member 132 can be clamps, and the first clamping member 131 and the second clamping member 132 can be opened and closed. The first clamping member 131 and the second clamping member 132 are closed simultaneously to clamp both sides of the membrane assembly 2 in the width direction 24, which helps to evenly clamp the membrane assembly 2 on both sides. Therefore, when the clamping assembly 13 moves the membrane assembly 2, the membrane assembly 2 is evenly attached to the first plate 14, the carrier 11, the second plate 15, and the second surface 32 of the product 3.

[0096] Optionally, the clamping assembly 13 further includes a crossbeam 137 , which connects the first clamping member 131 and the second clamping member 132 . The crossbeam 137 is used to simultaneously drive the first clamping member 131 and the second clamping member 132 to move.

[0097] In one embodiment, the first clamping member 131 includes a first clamping head 133 and a second clamping head 134, which are spaced apart along the length direction 23 of the membrane assembly 2 and are used to clamp one side edge of the second membrane segment 22 in the width direction 24. The second clamping member 132 includes a third clamping head 135 and a fourth clamping head 136, which are spaced apart along the length direction 23 of the membrane assembly 2 and are used to clamp the other side edge of the second membrane segment 22 in the width direction 24. The first clamping head 133 and the third clamping head 135 correspond to each other along the width direction 24 of the membrane assembly 2, and the second clamping head 134 and the fourth clamping head 136 correspond to each other along the width direction 24 of the membrane assembly 2. The film laminating device 1 further includes a cutter 17 for cutting the film assembly 2 between the clamping position of the first clamping head 133 and the third clamping head 135 and the clamping position of the second clamping head 134 and the fourth clamping head 136 .

[0098] Specifically, after the film assembly 2 has been applied to the front and back surfaces of the product 3, the first film segment 21 and the second film segment 22 face each other. The second clamping head 134 and the fourth clamping head 136 clamp the film assembly 2 to the left of the knife groove 172, while the first clamping head 133 and the third clamping head 135 clamp the film assembly 2 to the right of the knife groove 172. The blade 171 then cuts the film assembly 2. After cutting the film assembly 2, the second clamping head 134 and the fourth clamping head 136 release the film assembly 2. The product 3 is now removed from the carrier 11. The first clamping head 133 and the third clamping head 135 clamp the film assembly 2 and pull it to the second plate 15 for the next product 3 to be applied. The first clamping head 133 , the second clamping head 134 , the third clamping head 135 and the fourth clamping head 136 are respectively provided to clamp the four positions of the membrane assembly 2 , tightening the membrane assembly 2 at the four positions, which is conducive to the cutter 17 cutting the membrane assembly 2 .

The film laminating device 1 repeats the film laminating operation in this way.

[0103] When the film sticking device 1 provided in this embodiment is used:

[0104] In the first step, the membrane assembly 2 is mounted on the rack 16, the end of the membrane assembly 2 is loaded along the first plate 14, and then the first clamping head 133 and the third clamping head 135 are clamped on the end of the membrane assembly 2 along the width direction 24 (such as Figure 2 shown);

[0105] In the second step, the first clamping head 133 and the third clamping head 135 pull the membrane assembly 2 toward the second plate 15, so that the second membrane segment 22 corresponds to the second plate 15 and the first membrane segment 21 corresponds to the bearing surface 111. The bearing 11 is vacuumed and absorbs the first membrane segment 21. At this time, the first membrane segment 21 is attached and fixed to the bearing surface 111. The manipulator 33 places the first surface 31 of the product 3 on the bearing 11 in correspondence with the first membrane segment 21. The pressure rod 122 moves and presses between the first membrane segment 21 and the second membrane segment 22, and the pressure rod 122 presses the membrane assembly 2 into the groove 151 (as shown in FIG. Figure 3 shown);

[0106] In the third step, the first clamping head 133 and the third clamping head 135 release the membrane assembly 2, and the second clamping head 134 and the fourth clamping head 136 clamp the ends of the membrane assembly 2. The second clamping head 134 and the fourth clamping head 136 pull the second membrane segment 22 around the rotation axis 121 and flip it to fit the second surface 32. The second clamping head 134 and the fourth clamping head 136 release the membrane assembly 2. At this time, the membrane assembly 2 is attached to the front and back sides of the product 3 (such as Figure 4 shown);

[0107] In the fourth step, the second clamping head 134 and the fourth clamping head 136 clamp the membrane assembly 2 on the left side of the knife groove 172, and the first clamping head 133 and the third clamping head 135 clamp the membrane assembly 2 on the right side of the knife groove 172, and then the blade 171 cuts the membrane assembly 2 (such as Figure 5 shown).

[0108] In summary, the film-laminating device 1 provided in this embodiment first fits the first film segment 21 of the film assembly 2 and the first surface 31 of the product 3 through the supporting member 11, and then the film pressing assembly 12 cooperates with the supporting surface 111 and presses between the first film segment 21 and the second film segment 22, and the clamping assembly 13 cooperates with the film pressing assembly 12 and drives the second film segment 22 to flip relative to the first film segment 21 around the rotation axis 121 to fit the second surface 32 of the product 3, thereby realizing the flipping and fitting of the film assembly 2 to the product 3, so as to improve the position accuracy of the film assembly 2 fitting the front and back surfaces of the product 3.
