[0074] Figure 1 It is a schematic structural diagram of the film pasting device of this embodiment. As Figure 1 shown, the film pasting device includes a material feeding mechanism 1, a film pulling mechanism 2, a film peeling knife 3, a product loading mechanism 4, a side film pressing mechanism 5, a top film pressing mechanism 6, and a material collecting mechanism 7. Among them, the material film A extends from the material feeding mechanism 1 and moves along a predetermined path, passing through the film peeling knife 3 and the film pulling mechanism 2 in sequence to the material collecting mechanism 7. When the film pulling mechanism 2 pulls the material film A to the film peeling position, the film peeling knife 3 peels the film A2 from the tape A1. The product loading mechanism 4, through rotating the product D and cooperating with the side film pressing mechanism 5, completely pastes the peeled film A2 on the side of the product D. The top film pressing mechanism 6 completely pastes the remaining part of the film A2 on the top surface of the product D, improving the film pasting effect and making the film pasting effect stable. At the same time, the product loading mechanism 4, through rotating the product D and cooperating with the side film pressing mechanism 5, completely pastes the peeled film A2 on the sides of different sizes of the product D, enabling this film pasting device to be applicable to the surface film pasting of different types of products, with a relatively high speed, suitable for mass production, and reducing production costs.

[0075] In this application, the film A2 attached to the product D is electrostatically adsorbed on the tape A1 at equal intervals to form a material film A, and then wound around a reel for storage. That is, the material film A includes the tape A1 and multiple films A2, and the multiple films A2 are attached to the tape A1 at equal intervals, as Figure 2 shown. The shape of the film A2 is set according to requirements, and it can be used to protect the product surface and also for information display.

[0076] Figure 2 is a schematic structural diagram of the unwinding mechanism. The unwinding mechanism 1 is used to load the first reel B with the material film A. The unwinding mechanism 1 rotates to make the first reel B rotate for unwinding, so that the material film A subsequently peels off the film A2 and is pasted on the surface of the product D to complete the pasting. As Figure 2 shown, the unwinding mechanism 1 includes a first mounting frame 11, a first driving mechanism 12, and a first driving shaft 13.

[0077] The first driving mechanism 12 is fixed on the first mounting frame 11. The first driving shaft 13 is connected to the driving end of the first driving mechanism 12, and the first driving shaft 13 is used to load the first reel B with the material film A. Among them, the first driving mechanism 12 drives the first driving shaft 13 to rotate to drive the first reel B to rotate synchronously, thereby realizing unwinding.

[0078] In this embodiment, the first mounting frame 11 includes two first mounting plates 111 arranged in parallel, and the two first mounting plates 111 are connected by multiple connecting columns. Among them, coaxial through holes are provided on the two first mounting plates 111. A coupling is provided between the two first mounting plates 111. The housing part of the first driving mechanism 12 is fixed on the first mounting plate 111 below the first mounting frame 11 by bolts, etc. The driving end passes through the through hole and is connected to the coupling. The first driving shaft 13 is located above the first mounting frame 11 and the bottom end passes through the through hole of the upper first mounting plate 111 and is connected to the coupling, thereby realizing the connection between the first driving shaft 13 and the first driving mechanism 12. The first driving shaft 13 is rotatably connected to the first mounting frame 11. Optionally, the first driving shaft 13 is rotatably connected to the first mounting frame 11 through a bearing, which can improve the stability of the first driving shaft 13 during rotation. The part of the first driving shaft 13 located above the first mounting frame 11 can pass through the first reel B, and then be fixedly connected to both ends of the first reel B by bolts, etc., so that the first reel B is axially and circumferentially fixedly connected to the first driving shaft 13. When the first driving mechanism 12 drives the first reel B to rotate for unwinding through the first driving shaft 13, the stability and reliability of unwinding can be improved. Among them, the first driving mechanism 12 can be a motor, and the first reel B has the material film A.

[0079] Figure 3It is a schematic structural diagram of the film pulling mechanism. The film pulling mechanism 2 includes a second fixed plate, a first rotary driver 22, and a film pulling wheel 23. The film pulling mechanism 2 is located behind the feeding mechanism 1 and is used to pull the film A to move. Among them, the first rotary driver 22 is fixed on the second fixed plate, the film pulling wheel 23 is rotatably arranged on the second fixed plate and is connected to the first rotary driver 22, and the first rotary driver 22 drives the film pulling wheel 23 to rotate to pull the tape A1 to move. Among them, the film pulling wheel 23 is located behind the film stripping knife 3. The film pulling wheel 23 pulls the tape A1 so that the film A2 can pass through the film stripping knife 3 and be peeled off from the tape A1. At the same time, it can also assist the winding mechanism 7 to wind and recycle the empty tape.

[0080] In this embodiment, the film pulling mechanism 2 further includes a second mounting plate 24 arranged in parallel with the second fixed plate. The second mounting plate 24 is connected below the second fixed plate through a vertical connecting plate. A coupling is arranged between the second fixed plate and the second mounting plate 24. The housing part of the first rotary driver 22 is fixed below the second mounting plate 24 by bolts or the like. The driving end of the first rotary driver 22 is connected to the connecting shaft in the film pulling wheel 23 through the coupling, thereby realizing the connection between the first rotary driver 22 and the film pulling wheel 23. Among them, the first rotary driver 22 can be a motor. A guide wheel 32 can also be arranged according to needs behind the film pulling wheel 23. Among them, the guide shaft in the guide wheel 32 is fixedly arranged on the second fixed plate, and the guide wheel 32 can rotate relative to the guide shaft.

[0081] The film stripping knife 3 is located between the feeding mechanism 1 and the film pulling mechanism 2, which enables the film A pulled by the film pulling mechanism 2 to pass through the film stripping knife 3 for peeling. The film stripping knife 3 is used to peel the film A2 at the film stripping position from the tape A1.

[0082] In this embodiment, the film stripping knife 3 is fixedly arranged on the second fixed plate and is located on the front side of the film pulling wheel 23. Among them, the height of the film stripping knife 3 can be set according to requirements. If the height is not enough, a fixed block can be arranged below it for adjustment to ensure that the height of the film A at the film pulling wheel 23, the film stripping knife 3, and other positions is the same, ensuring smooth peeling and flat product film pasting.

[0083] Among them, the side of the film stripping knife 3 close to the film pulling mechanism 2 is an acute-angled tip, that is, the film stripping position, which is used to strip the film A2; the angle at one end of the film stripping knife 3 close to the feeding mechanism 1 is not set. In this embodiment, the film stripping knife 3 includes a through groove 31 through which the feeding film A passes, and is used to limit the movement of the film A in the height direction. Among them, one end of the film stripping knife 3 at the through groove 31 is acute-angled and is used to strip the film A2. Among them, the width of the through groove 31 is basically the same as the width of the film A, so that after the film A passes through the through groove 31, it is ensured that the film A will not shake in the height direction, improving the stability of film stripping and ensuring the flatness of the surface film on the product. In addition, guide wheels 32 are respectively arranged on both sides of the through groove 31. The guide wheel 32 close to the inlet end of the through groove 31 is used to guide the film A into the through groove 31 to prevent it from being damaged by the end of the through groove 31; the guide wheel 32 close to the outlet end of the through groove 31 is used to guide the film A into the film pulling mechanism 2. The guide wheel 32 has the same structure as the guide wheel 32 near the film pulling wheel 23. In addition, the guide wheel 32 can be replaced by a circular guide post.

[0084] When the film A passes through the film stripping position, an acute angle is formed. When the film A2 passes through this position, it can be separated from the tape A1, and the static electricity is removed by the blowing mechanism, so as to be attached to the surface of the product D.

[0085] Figure 7 It is a schematic structural diagram of the product loading mechanism. The product loading mechanism 4 is arranged on one side of the film stripping position of the film stripping knife 3. The product loading mechanism 4 is used to load and place the product D, so that the film A2 stripped by the film stripping knife 3 can be attached to the surface of the product D.

[0086] As Figure 7 shown, the product loading mechanism 4 includes a first fixing frame 41, a second rotary driver 42, a first rotary shaft 43 and a product insert 44. The first fixing frame 41 is located on one side of the second fixing plate and close to the film stripping position. The second rotary driver 42 is fixed on the first fixing frame 41. The first rotary shaft 43 is drivingly connected to the second rotary driver 42. The product insert 44 is fixed on the top of the first rotary shaft 43, and the product D is fixed on the product insert 44. The position of the product D is close to the film stripping position. The second rotary driver 42 drives the product D to rotate through the first rotary shaft 43 and the product insert 44, so that the film A2 can be attached to different sides of the product D. At the same time, during the rotation of the product D, the side film pressing mechanism 5 cooperates to press the film A2 flat on the side of the product D, improving the film sticking effect and the film sticking efficiency.

[0087] In this embodiment, the first fixing frame 41 includes an L-shaped fixing frame 411 and a limiting block 412. The limiting block 412 is fixedly connected to the longitudinal side of the L-shaped fixing frame 411. A receiving space is formed between the transverse side of the L-shaped fixing frame 411 and the limiting block 412. As Figure 7As shown in the figure. Among them, coaxial through holes are provided on the lateral side of the L-shaped fixing bracket 411 and the limiting block 412, and a coupling is provided between the two. The housing part of the second rotary driver 42 is fixed below the lateral side of the L-shaped fixing bracket 411 by bolts or the like, and the driving end passes through the through hole and is connected to the coupling. The first rotating shaft 43 is rotatably connected within the limiting block 412 and passes through both ends respectively. One end is connected to the coupling, and the other end is used to connect to the product insert 44. Thus, the second rotary driver 42 and the first rotating shaft 43 are connected. Optionally, the first rotating shaft 43 is rotatably connected to the limiting block 412 through a bearing, which can improve the stability of the first rotating shaft 43 during rotation, thereby improving the stability of the rotation of product D and improving the film sticking effect. Among them, the second rotary driver 42 can be a motor.

[0088] Among them, the top of the first rotating shaft 43 has a U-shaped mounting hole, and the lower half of the product insert 44 can be inserted into the U-shaped mounting hole, and then the two are firmly connected by fasteners such as bolts. The upper half of the product insert 44 is adapted to the inner shell of the product D, so that the product D can be sleeved on the outside of the product insert 44 from top to bottom, thereby exposing the side and top surfaces to be film-stuck, and at the same time preventing the problem of displacement during rotation and film sticking. In addition, the product D and the product insert 44 can also be set to other cooperable connection structures, such as snap-fit slots, magnetic attraction and other structures.

[0089] As Figure 7 As shown in the figure, the product loading mechanism 4 further includes a limiting plate 45, a second sliding assembly 46 and a positioning rod assembly 47. The limiting plate 45 is arranged parallel to the side surface of the first fixing bracket 41, and the two are slidably connected through the second sliding assembly 46. One end of the positioning rod assembly 47 passes through the top of the limiting plate 45 and is fixedly connected to the first fixing bracket 41, and the other side is fixed, thereby fixing the product insert 44 after adjusting the height at a specified height to meet the height requirement of the product D.

[0090] In this embodiment, the limiting plate 45 is an inverted L-shaped structure. The longitudinal part of the limiting plate 45 is arranged parallel to the longitudinal side of the L-shaped fixing bracket, and the top of the limiting plate 45 is located above the longitudinal side of the L-shaped fixing bracket. The positioning rod assembly 47 includes a positioning rod and a locking member. One end of the positioning rod passes through the top of the limiting plate 45 and is fixedly connected to the top of the longitudinal side of the L-shaped fixing bracket, and the limiting plate 45 can slide up and down relative to the longitudinal side of the L-shaped fixing bracket. The locking member is connected to the positioning rod. Among them, the limiting plate 45 is fixed on other mechanical structures or devices and remains stationary. When the height of the product insert 44 needs to be adjusted, the height of the product insert 44 is adjusted by adjusting the height of the longitudinal side of the L-shaped fixing bracket. After adjustment, the height of the positioning rod changes, and then the positioning rod is locked at this height by the locking member, thereby realizing the height adjustment and locking of the product D. Among them, the second sliding assembly 46 is a cooperating slider and slide rail.

[0091] As shown Figure 4 in the figure, the side film pressing mechanism 5 is located on one side of the product loading mechanism 4, and the side film pressing mechanism 5 is used to press the peeled part of the film A2 flat on the side of the product D.

[0092] As shown Figure 8 in the figure, the side film pressing mechanism 5 includes a first fixing plate, a first linear motion module 52, a second connecting rod 53 and a side roller 54. Among them, the first linear motion module 52 is arranged on the first fixing plate, one end of the second connecting rod 53 is connected to the first linear motion module 52, the other end of the second connecting rod 53 extends towards the side of the product loading mechanism 4, and the side roller 54 is rotatably connected to one end of the second connecting rod 53 close to the product loading mechanism 4. Among them, the first linear motion module 52 is used to drive the side roller 54 to approach the product D through the second connecting rod 53 and press the film A2 on the side of the product D.

[0093] Among them, the first fixing plate and the second fixing plate can be the same fixing plate E, or can be different fixing plates. When the first fixing plate and the second fixing plate are different fixing plates, that is, the side film pressing mechanism 5 is integrally arranged on one side of the film peeling knife 3 and the film pulling mechanism 2.

[0094] In this embodiment, the first fixing plate and the second fixing plate are the same fixing plate E. That is, the film pulling mechanism 2, the film peeling knife 3 and the side film pressing mechanism 5 are arranged on the same fixing plate E, reducing the machine size of the overall equipment. Among them, the film peeling knife 3 is located between the film pulling mechanism 2 and the side film pressing mechanism 5.

[0095] Among them, the first linear motion module 52 can be a linear drive mechanism such as a ball screw or a linear cylinder. In this embodiment, the first linear motion module 52 is inclined with respect to the film peeling knife 3. The central axis of the side roller 54 is parallel to the height direction, which makes the outer side surface of the side roller 54 parallel to the side surface of the product D, facilitating the pressing of the film A2 on the side surface of the product D. Preferably, the height of the outer side surface of the side roller 54 is greater than the height of the side surface of the product D, so as to completely cover and press the film A2 during the pressing process.

[0096] The side film pressing mechanism 5 further includes an adapter 55 and a plurality of first elastic connectors 56, as shown Figure 8 in the figure. Among them, the adapter 55 is connected to the first linear motion module 52. The adapter 55 includes an installation through groove 551 with a lateral opening. One end of the second connecting rod 53 is movably connected in the installation through groove 551, and the other end of the second connecting rod 53 extends out of the installation through groove 551 and extends towards the side of the product loading mechanism 4. The second connecting rod 53 located in the installation through groove 551 is connected to the inner wall of the installation through groove 551 through a plurality of first elastic connectors 56.

[0097] Among them, the product loading mechanism 4 drives the product D to rotate. The first linear motion module 52 drives the side roller 54 to move closer to the product D through the second connecting rod 53, and presses the film A2 peeled off by the film peeling knife 3 completely on the side of the product D. Since the distance between the different sides of the product D and the side roller 54 changes when the product D rotates, the side roller 54 is pushed to move to keep the side roller 54 in a pressing connection with the different sides of the product D all the time. To avoid pressing the film A2 too hard by the side roller 54 against the side of the product D and breaking the film A2, the side roller 54 can change its position by compressing a plurality of first elastic connectors 56, so as to adapt to the different sides of the product D and improve the film sticking effect. Further, the plurality of first elastic connectors 56 make the side roller 54 maintain the pressure on the side of the product D through elastic force, so that the film A2 can be tightly stuck on the side of the product D. At the same time, one end of the second connecting rod 53 is connected in the installation through groove 551 through the first elastic connector 56, which limits the height direction of the second connecting rod 53 by the installation through groove 551, avoids the side roller 54 from moving along the height direction, and improves the film sticking effect.

[0098] As Figure 1 shown, the top surface film pressing mechanism 6 is located on one side of the product loading mechanism 4, and the top surface film pressing mechanism 6 is used to press part of the film A2 flat on the top surface of the product D. As Figure 5 and Figure 6 shown, the top surface film pressing mechanism 6 includes a first linear motion component 61, a second linear motion component 62, a connecting component 63 and a top wheel 64. Among them, the first linear motion component 61 moves in the horizontal direction, and the second linear motion component 62 can move in the height direction. The second linear motion component 62 is connected above the first linear motion component 61. One end of the connecting component 63 is fixedly connected to the second linear motion component 62, and the other end extends toward the side of the product loading mechanism 4. The top wheel 64 is rotatably connected to one end of the connecting component 63 close to the product loading mechanism 4, and the central axis of the top wheel 64 is parallel to the top surface of the product D.

[0099] Among them, the second linear motion component 62 can drive the top wheel 64 to move in the height direction through the connecting component 63, so that the top wheel 64 can move above the top surface of the product D. The first linear motion component 61 drives the second linear motion component 62 and the top wheel 64 to move laterally, so that the top wheel 64 can pass over the product D. The connecting component 63 includes two connecting pieces with different structures, and the two connecting pieces are connected by fasteners. Among them, the two connecting pieces can be aligned and connected at different positions through fasteners to realize the adjustment of the overall length of the connecting component 63, so that the top wheel 64 can be exactly located directly above the product D. One of the connecting pieces is used for fixedly connecting with the second linear motion component 62, and the other connecting piece is connected with the top wheel 64.

[0100] During the process of applying a film to the top surface of product D: First, the second linear motion component 62 lifts the top wheel 64 to a position higher than the top surface of product D. Then, the first linear motion component 61 is controlled to drive the top wheel 64 to move above product D. Then, the first linear motion component 61 and the second linear motion component 62 cooperate to make the top wheel 64 press on the top surface of product D and roll over to flatten the film A2 on the top surface.

[0101] As Figure 5 and Figure 6 shown, the top surface film pressing mechanism 6 further includes a third sliding component 65 and a second elastic connecting member 66. The third sliding component 65 includes a sliding rail and a slider that are fitted and connected. The sliding rail is installed on the outer side surface of the second linear motion component 62 along the height direction, and the top of the slider is fixedly connected to the connecting component 63. One end of the second elastic connecting member 66 is connected to the connecting component 63 through the slider, and the other end of the second elastic connecting member 66 is connected to the outer side surface of the second linear motion component 62. Among them, during the process of the top wheel 64 rolling over the top surface of product D, the second elastic connecting member 66 pulls the top wheel 64 to press on the top surface of product D through elastic force, thereby ensuring that the film can be flattened on the top surface of product D.

[0102] In this embodiment, after the side surface film pressing mechanism 5 applies the film A2 to the side surface of product D, at this time, the film pulling mechanism 2 is controlled to stop pulling the film, and then the top surface film pressing mechanism 6 is controlled to apply the film A2 to the top surface of product D.

[0103] Among them, the first linear motion component 61 and the second linear motion component 62 can be linear drive mechanisms such as ball screws and linear cylinders.

[0104] As Figure 4 shown, the film applying device further includes a blowing mechanism 8, which is located on one side of the film peeling position of the film peeling knife 3. The blowing mechanism 8 assists the film peeling knife 3 to peel off the film A2 by blowing air to the peeling position. There is static electricity on the film A2. The blowing mechanism 8 can remove the static electricity on the film A2 by blowing air to the film A2, preventing the film A2 from being directly adsorbed on product D and causing poor film application. The blowing mechanism 8 is provided with a plurality of air blowing holes along the height direction, and the other end of the air blowing holes is connected to a gas supply device, etc. In this embodiment, the blowing mechanism 8 and the film peeling knife 3 are arranged on the same fixed plate, located at the rear side of the film peeling knife 3, and it can blow the gas to the peeling position.

[0105] As Figure 9 and Figure 10As shown in the figure, the film pasting device further includes a first sliding assembly 91, a first connecting rod 92, and a first sensor 93. The first sliding assembly 91 is installed on the top of the film stripping knife 3. One end of the first connecting rod 92 is fixedly connected to the first sliding assembly 91, and the other end of the first connecting rod 92 extends towards the outside of the through groove 31. The first sensor 93 is fixed to the end of the first connecting rod 92 that extends outwards. The first sensor 93 is used to detect the position of the film A2, so as to control the movement of the material film A so that the film A2 can be accurately pasted on the surface of the product D. The first sliding assembly 91 is used to drive the first sensor 93 to move, so that the first sensor 93 can meet the detection of the position of the film A2.

[0106] As Figure 1 shown in the figure, the material collecting mechanism 7 is located outside the top surface film pressing mechanism 6. The material collecting mechanism 7 is used to roll up the stripped material tape A1 for recycling. Among them, the structures of the material collecting mechanism 7 and the material feeding mechanism 1 are similar, and both realize material feeding or material collecting by controlling the rotation of the reel.

[0107] As Figure 2 shown in the figure, the material collecting mechanism 7 includes a second mounting frame 71, a second driving mechanism 72, and a second driving shaft 73. The second driving mechanism 72 is fixed on the second mounting frame 71. The second driving shaft 73 is connected to the driving end of the second driving mechanism 72. The second driving shaft 73 is used to load the second reel. Among them, the second driving mechanism 72 drives the second driving shaft 73 to rotate to drive the second reel to rotate synchronously, so as to realize the material collection of the material tape A1 after the film A2 is peeled off. Among them, the structure of the second mounting frame 71 can be the same as or different from that of the first mounting frame 11, which is specifically set according to requirements. The second driving mechanism 72 and the second driving shaft 73 can be connected by a coupling. Among them, the second driving mechanism 72 can be a motor.

[0108] As Figure 1 and Figure 2 shown in the figure, the film pasting device further includes a guide roller mechanism 10, which is located between the material feeding mechanism 1 and the film stripping knife 3. The guide roller mechanism 10 is used to provide a path for the material film A. Among them, the material film A extends from the material feeding mechanism 1 and is guided by the guide roller mechanism 10 to move along a predetermined path and sequentially passes through the film stripping knife 3, the film pulling mechanism 2 to the material collecting mechanism 7.

[0109] As Figure 2As shown in the figure, the guide roller mechanism 10 includes a fourth sliding component 101, a first guide roller 102, a second guide roller 103, a second sensor 104, and a third sensor 105. The fourth sliding component 101 is arranged on one side of the feeding mechanism 1, specifically on the side surface of the first mounting frame 11. The first guide roller 102 is rotatably arranged on the feeding mechanism 1, specifically on the top surface of the first mounting frame 11. The second guide roller 103 is rotatably arranged on the fourth sliding component 101. The second sensor 104 and the third sensor 105 are respectively arranged at both ends of the fourth sliding component 101, and the second sensor 104 and the third sensor 105 are used to detect the position of the second guide roller 103. The material film A extends from the feeding mechanism 1 and is guided into the film peeling knife 3 through the first guide roller 102 and the second guide roller 103. Among them, the fourth sliding component 101 drives the second guide roller 103 to move, so as to control the moving speed and position of the material film A through the movement of the second guide roller 103, thereby realizing the control of the feeding of the feeding mechanism 1.

[0110] In this embodiment, during the process of the side film pressing mechanism 5 attaching the film A2 to the side surface of the product D, the film pulling mechanism 2 continuously pulls the material film A to move. When the film A2 is completely attached to the side surface of the product D, at this time, the first sensor 93 detects that the position of the film A2 bends away from the material tape A1, and at this time, the film pulling mechanism 2 is controlled to stop pulling the film; then the top surface film pressing mechanism 6 is controlled to attach the film A2 to the top surface of the product D.

[0111] In this embodiment, the material film A takes the guide roller mechanism 10, the film peeling knife 3, and the film pulling mechanism 2 as the path. The manipulator picks up the product D from the material tray and places it on the product insert 44. The first rotary driver 22 drives the film pulling wheel 23 to pull the material tape A1. When the film pulling wheel 23 is stressed to a certain position, the feeding mechanism 1 feeds the material. The film peeling knife 3 peels off the film A2, and the blowing mechanism 8 assists in peeling; at this time, the first linear motion module 52 moves closer and presses the side roller 54 on the side surface of the product D. At the same time, the second rotary driver 42 drives the first rotary shaft 43 to rotate, that is, the product insert 44 and the product D rotate, and the film A2 is attached to the product D. The first elastic connecting piece 56 is used to adapt to the large and small surfaces of the product D to attach the film A2 firmly; the film pulling mechanism 2 stops pulling the film according to the position detected by the first sensor 93 when the film A2 arrives; the top wheel 64 is lifted by the second linear motion component 62, and the first linear motion component 61 drives the top wheel 64 to move above the product D. Then, the first linear motion component 61 and the second linear motion component 62 cooperate, relying on the pulling force of the second elastic connecting piece 66, so that the top wheel 64 keeps pressing on the top surface of the product D and rolls over the flattened top film A2. The waste material tape A1 is wound up by the material collecting mechanism 7, and the mechanism completes the operation.

[0112] The film sticking device of this embodiment has a simple structure and wide applicability, can be applied to various types of products in large, medium and small batches, has a high film sticking yield, stable effect, and few pressing injuries.
