Description

Technical Field

[0001] This application relates to the field of product film application technology, specifically to a film application device. Background Technology

[0002] In actual production and processing, it is often necessary to apply a film to products to protect their appearance. For example, before stamping, a film needs to be applied to prevent scratches and abrasions during product movement and stamping, thus ensuring a high yield rate. Currently, film application is usually done manually, with the film repeatedly pressed to ensure a tight fit. However, manual film application suffers from high labor costs and low film application accuracy. Summary of the Invention

[0003] In view of the above, it is necessary to propose a film-applying device to replace manual film application, reduce labor costs, and improve the film application accuracy.

[0004] This application provides a film applicator, including a transmission mechanism, a film supply mechanism, a first film pressing mechanism, a second film pressing mechanism, and a film cutting mechanism. The transmission mechanism includes a frame and a conveyor belt rotatably mounted on the frame. The conveyor belt carries the product to be applicated and moves the product. The film supply mechanism is mounted on the frame and located above the conveyor belt, supplying film components. The first film pressing mechanism is mounted on the frame and located above the conveyor belt. The first film pressing mechanism is located at one end of the film supply mechanism and includes a film pressing assembly.

The film passes through the tensioning assembly and the plurality of guide rollers to be received by the film pressing assembly. When the film is connected to the product on the conveyor belt, the tensioning assembly presses against the film to tension it.

[0006] In some embodiments, the film supply mechanism further includes a stamping assembly disposed on the frame and located on the movement path of the film. The stamping assembly includes a support and a stamping member disposed above the support. The film passes between the support and the stamping member, and the stamping member moves toward the support to stamp and punch holes in the film.

[0007] In some embodiments, the film feeding mechanism further includes a receiving member disposed on the frame and located below the support member, the receiving member collecting the film pieces punched off by the stamping member.

[0008] In some embodiments, the first pressing mechanism further includes a first driving member, which is disposed on the frame and connected to the pressing assembly, and drives the pressing assembly to move closer to or away from the conveyor belt.

[0009] In some embodiments, the film pressing assembly includes a connecting plate, a connecting shaft, a pressure plate, a base plate, a guide member, an elastic member, a receiving roller shaft, and a pressing roller shaft. There are two connecting plates, which are arranged opposite to each other. The connecting shaft connects the two connecting plates and is connected to the first driving member. The pressure plate is connected between the two connecting plates. The base plate is connected to the two connecting plates and is located below and spaced apart from the pressure plate. The guide member is movably inserted through one of the connecting plates and connected to the base plate. The elastic member is sleeved on the guide member and located on the side of the connecting plate opposite to the base plate. The receiving roller shaft is rotatably disposed between the two connecting plates and located on one side of the pressure plate. The pressing roller shaft is rotatably disposed between the two connecting plates and located on the other side of the pressure plate. The film sequentially passes through the receiving roller shaft, the gap between the pressure plate and the base plate, and the pressing roller shaft.

[0010] In some embodiments, the bottom plate has a plurality of spaced clearance grooves on the side facing the pressure plate.

[0011] In some embodiments, the second pressing mechanism further includes a second driving member and a mounting base, the second driving member being disposed on the frame, the mounting base being connected to the second driving member, and the pressing roller shaft being rotatably disposed on the mounting base.

[0012] In some embodiments, the film cutting mechanism further includes a film cutting drive, a film cutting slide rail, a film cutting slider, and a clamping member. The film cutting drive is disposed on the frame, the film cutting slide rail is disposed on the frame, the film cutting slider is slidably disposed on the film cutting slide rail, the clamping member is connected to the film cutting slider and the film cutting drive, and the cutting member is connected to the clamping member. The film cutting drive drives the clamping member and the film cutting slider to slide along the film cutting slide rail, so that the cutting member moves to cut the film.

The distance between the first flat-pressing roller shaft and the conveyor belt and the distance between the second flat-pressing roller shaft and the conveyor belt are equal and both are less than the distance between the third flat-pressing roller shaft and the conveyor belt.

[0014] In use, the above-mentioned film application device involves a film supply mechanism supplying film components. The film pressing assembly of the first film pressing mechanism receives the film components supplied by the film supply mechanism. The product to be filmed is placed on the conveyor belt of the transport mechanism. The conveyor belt moves the product below the film pressing assembly, and the film pressing assembly, along with the film components it receives, moves closer to the conveyor belt, causing the film components to connect with the product on the conveyor belt under the action of the film pressing assembly. After the film components are connected to the product, the conveyor belt moves the product connected to the film components to below the film pressing roller shaft of the second film pressing mechanism, and the film pressing roller shaft moves closer to the conveyor belt. The film and product are connected by a pressure roller. After the pressure roller presses against the connected film and product, the conveyor belt continues to move the product connected to the film until the film is completely adhered to the product. The cutting component of the film cutting mechanism moves in a direction perpendicular to the movement of the conveyor belt to cut the film. The cut film and product move to a designated position under the drive of the conveyor belt, thereby realizing the mechanized film application of the film and product. At the same time, after the cutting component cuts the film, the pressure roller assembly and the pressure roller move away from the conveyor belt to facilitate the application of film to the next product to be filmed.

[0015] The film-applying device provided in this application embodiment, through the cooperation of the transmission mechanism, film supply mechanism, first film pressing mechanism, second film pressing mechanism, and film cutting mechanism, realizes mechanized operations for product transmission, film supply, film pressing connection, film pressing and bonding, and film cutting. It effectively replaces manual film application, reduces labor costs, and improves film application efficiency and production capacity. Due to the mechanized operation, it can achieve standardized film application, reduce errors caused by manual film application, and improve the bonding accuracy of film components. In addition, by pressing the film components and products connected by the film pressing roller of the second film pressing mechanism, air bubbles between the film components and products can be expelled, improving the film application yield.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, it should be noted that "a plurality of" means two or more, unless otherwise explicitly specified.

[0085] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between the two components; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0086] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0087] Please see Figure 1 and Figure 2 This application provides a film application device 100 for attaching a film component 200 to a product 300. The product 300 can be a plate-shaped object such as a laptop casing or mobile phone casing. The film component 200 can be attached to the product 300 using an adhesive or by electrostatic adsorption. Figure 1 and Figure 2 The arrow shown indicates the direction of movement of product 300.

[0088] The film application device 100 includes a transmission mechanism 10, a film supply mechanism 20, a first film pressing mechanism 30, a second film pressing mechanism 40, and a film cutting mechanism 50. The transmission mechanism 10 receives and moves the product 300 to be filmed, and also moves the filmed product 300 to a designated position, which can be understood as the end of the transmission mechanism 10 or a position on the transmission mechanism 10 where the filmed product 300 can be removed. The film supply mechanism 20 continuously supplies the film 200. The first film pressing mechanism 30 presses the film 200 onto the product 300, thus connecting the film 200 and the product 300. The second pressing mechanism 40 is used to further press the film 200 bonded to the product 300, on the one hand to remove air bubbles between the film 200 and the product 300, ensuring the film 200 bonding yield, and on the other hand to ensure that the film 200 is tightly bonded to the product 300. The film cutting mechanism 50 is used to cut the film 200 so that the product 300 after the film 200 is bonded can be moved individually to a designated position.

[0089] Specifically, the transmission mechanism 10 includes a frame 11 and a transmission belt 12 rotatably mounted on the frame 11. The transmission belt 12 is used to support the product 300 to be applied and to move the product 300. The transmission belt 12 is also used to move the product 300 after application to a designated position. The film supply mechanism 20 is mounted on the frame 11 and located above the transmission belt 12. The film supply mechanism 20 is used to supply film 200. The first film pressing mechanism 30 is mounted on the frame 11 and located above the transmission belt 12. The first film pressing mechanism 30 is located at one end of the film supply mechanism 20. The first film pressing mechanism 30 includes a film pressing assembly 31. The film pressing assembly 31 can move closer to or away from the transmission belt 12. The film pressing assembly 31 is used to receive the film 200 supplied by the film supply mechanism 20 and move the film 200 together with it closer to the transmission belt 12, so that the film 200 is connected to the product 300 on the transmission belt 12 under the driving action of the film pressing assembly 31. The second film pressing mechanism 40 is disposed on the frame 11 and located above the conveyor belt 12. The second film pressing mechanism 40 is located on the side of the first film pressing mechanism 30 away from the film supply mechanism 20. The second film pressing mechanism 40 includes a film pressing roller 41, which can move closer to or away from the conveyor belt 12. The film pressing roller 41 is used to move closer to the conveyor belt 12 to press against the connected film 200 and product 300. The film cutting mechanism 50 is disposed on the frame 11 and located above the conveyor belt 12. The film cutting mechanism 50 is located between the first film pressing mechanism 30 and the second film pressing mechanism 40. The film cutting mechanism 50 includes a cutting element 51, which can move in a direction perpendicular to the movement of the conveyor belt 12 to cut the film 200. It is understood that the "roller" defined in the embodiments of this application can be made of Teflon or other materials with good non-stick properties.

[0090] In actual use, the film applicator 100 of this embodiment supplies film 200 to the film supplying mechanism 20. The film pressing assembly 31 of the first film pressing mechanism 30 receives the film 200 supplied by the film supplying mechanism 20. The product 300 to be applicated is placed on the conveyor belt 12 of the conveying mechanism 10. The conveyor belt 12 moves the product 300 below the film pressing assembly 31. The film pressing assembly 31, along with the film 200 it receives, moves closer to the conveyor belt 12, so that the film 200 connects to the end of the product 300 on the conveyor belt 12 under the driving action of the film pressing assembly 31. After the film 200 is connected to the end of the product 300, the conveyor belt 12 continues to move the product 300. As the product 300 moves, the film 200 continuously adheres to the product 300. When the conveyor belt 12 moves the product 300 connected to the film 200 to below the film pressing roller 41 of the second film pressing mechanism 40, the film pressing roller... The shaft 41 moves close to the conveyor belt 12 to press against the connected film 200 and product 300 to further press the film 200. After the pressure roller shaft 41 presses against the connected film 200 and product 300, the conveyor belt 12 continues to move the product 300 connected to the film 200 until the film 200 is completely adhered to the product 300. When the tail end of the product 300 with the film 200 adhered passes the cutting part 51 of the film cutting mechanism 50, the cutting part 51 moves in a direction perpendicular to the movement of the conveyor belt 12 to cut the film 200. The cut film 200 and product 300 move to the designated position under the drive of the conveyor belt 12, thereby realizing the film application operation of the film 200 and product 300. At the same time, after the cutting part 51 cuts the film 200, the pressure assembly 31 and the pressure roller shaft 41 move away from the conveyor belt 12 to facilitate the film application operation of the next product 300 to be filmed. It should be noted that during the process of conveying product 300, the actions of the film pressing assembly 31 approaching the conveyor belt 12 to press the film 200 onto the product 300, the actions of the film pressing roller 41 approaching the conveyor belt 12 to further press the film 200, the actions of the cutting piece 51 cutting the film 200, the actions of the film pressing assembly 31 moving away from the conveyor belt 12, and the actions of the film pressing roller 41 moving away from the conveyor belt 12 are all completed relatively quickly. During the entire film application process, it is possible to choose not to stop so that the conveyor belt 12 continuously conveys product 300, that is, the conveyor belt 12 is always in the state of conveying product 300, thereby enabling the film application operation to be completed efficiently and quickly, improving film application efficiency and film application capacity. Multiple products 300 are placed at intervals. Understandably, in other embodiments, the entire film application process may be selectively paused so that the conveyor belt 12 pauses when conveying the product 300 to, for example, below the film pressing assembly 31 and below the film pressing roller 41, so as to complete the corresponding film pressing operation. The specific settings can be made according to the actual situation, and will not be described in detail in the embodiments of this application.

[0091] Please see Figure 3In this embodiment of the application, the frame 11 may include a bracket 111, a first support plate 112, a second support plate 113, a support base 114, and a reinforcement component 115. The support 111 is roughly table leg shaped. The conveyor belt 12 is rotatably disposed inside the support 111. The first support plate 112 and the second support plate 113 are arranged opposite each other and are both located above the support 111. There are multiple support seats 114. The first support plate 112 and the second support plate 113 are connected to the support 111 through the support seats 114. It can be understood that the first support plate 112 and the second support plate 113 can be complete plate-shaped objects or can be composed of multiple plate-shaped objects arranged at intervals. The shapes of the first support plate 112 and the second support plate 113 can be the same or different, depending on the actual situation. There can be two reinforcing members 115. The two reinforcing members 115 are arranged at intervals and are both connected between the first support plate 112 and the second support plate 113. The two reinforcing members 115 are both located above the first support plate 112 and the second support plate 113. There can also be more reinforcing members 115. The film supply mechanism 20, the first film pressing mechanism 30, the second film pressing mechanism 40, and the film cutting mechanism 50 are all disposed between the first support plate 112 and the second support plate 113. Thus, by configuring the specific structure of the frame 11 described above, the frame 11 can rotate to accommodate the conveyor belt 12, and can also accommodate the film supply mechanism 20, the first film pressing mechanism 30, the second film pressing mechanism 40, and the film cutting mechanism 50.

[0092] In this embodiment, the transmission mechanism 10 may further include a power component 13. The power component 13 is mounted on the support 111 of the frame 11 and connected to the transmission belt 12. The power component 13 is used to drive the transmission belt 12 to rotate. The power component 13 may consist of a motor, rollers, or other structures. Thus, by providing the aforementioned power component 13, the transmission belt 12 is made to rotate.

[0093] To limit the position of product 300, ensure the relative positional accuracy between product 300 and film 200, and improve the bonding accuracy between product 300 and film 200, in this embodiment, the transmission mechanism 10 may further include a limiting component 14, which includes multiple limiting members 141 and multiple connecting members 142. Each limiting member 141 is generally rod-shaped, and each connecting member 142 is generally L-shaped. The multiple limiting members 141 are evenly distributed on both sides of the support 111 according to the size of product 300, and each limiting member 141 is connected to the support 111 through one or more connecting members 142. Each limiting member 141 is spaced apart from the transmission belt 12. The multiple limiting members 141 are used to limit the product 300 on the transmission belt 12, so that the product 300 moves along the area defined by the multiple limiting members 141. Thus, by setting the aforementioned limiting component 14, the product 300 is limited, preventing the product 300 from shifting during movement, ensuring the relative positional accuracy between the product 300 and the film 200, thereby improving the bonding accuracy between the product 300 and the film 200.

[0094] Please see Figure 4In this embodiment of the application, the film supply mechanism 20 includes a rotating frame 21, a tensioning assembly 22, and a guiding assembly 23. The rotating frame 21 is rotatably disposed between the first support plate 112 and the second support plate 113 of the frame 11. The tensioning assembly 22 is disposed on the first support plate 112 of the frame 11. The guiding assembly 23 includes a plurality of guide rollers 231 rotatably disposed between the first support plate 112 and the second support plate 113 of the frame 11. The plurality of guide rollers 231 are arranged sequentially according to the moving path of the film 200. The rotating frame 21 is used to hang the wound film 200. The film 200 passes through the tensioning assembly 22 and the plurality of guide rollers 231 at the beginning of the rotating frame 21 and is received by the film pressing assembly 31. The tensioning assembly 22 is located between the plurality of guide rollers 231. When the film 200 is connected to the product 300 on the conveyor belt 12, the tensioning assembly 22 presses against the film 200 to make the film 200 in a tensioned state, so as to facilitate the smooth movement of the film 200 and better fit on the product 300. Thus, by setting the specific structure of the film supply mechanism 20, it is possible to continuously supply the film 200. Furthermore, through the cooperation of the tensioning assembly 22, the film 200 can be in both relaxed and tensioned states. When the tensioning assembly 22 is not tensioning the film 200, the film 200 is in a relaxed state with a movable allowance. The pressing assembly 31 can move the film 200 closer to the conveyor belt 12, thereby connecting the film 200 to the product 300. After the film 200 is connected to the product 300, the tensioning assembly 22 tensions the film 200, placing it in a tensioned state to facilitate smooth movement and a relatively flat and good fit onto the product 300. Additionally, by providing the rotating frame 21 to hang the wound film 200, the increased material costs due to the use of sheet film are reduced.

[0095] Understandably, in this embodiment of the application, the number of guide rollers 231 in the guide assembly 23 is, for example, five. Of course, the number of guide rollers 231 in the guide assembly 23 can be more or less, and can be set according to the actual situation. This embodiment of the application does not limit this.

[0096] Furthermore, in this embodiment, the tensioning assembly 22 includes a tensioning drive 221 and a tensioning member 222. The tensioning drive 221 can be a motor and is mounted on the first support plate 112 of the frame 11. The tensioning member 222 can be a rod-shaped object located between the first support plate 112 and the second support plate 113 and connected to the tensioning drive 221. The tensioning member 222 is located above the membrane 200. The tensioning drive 221 drives the tensioning member 222 to rotate, causing the tensioning member 222 to move closer to or further away from the membrane 200, thereby abutting or releasing the membrane 200, so that the membrane 200 is in a tensioned or relaxed state. Thus, by setting the specific structure of the tensioning assembly 22 as described above, the tensioning assembly 22 can tension and relax the membrane 200. In addition, the structure of the tensioning assembly 22 is simple, which helps to reduce equipment costs. Understandably, in other embodiments, the tensioning drive 221 can also be a linear cylinder, which drives the tensioning member 222 to move linearly so that the tensioning member 222 moves closer to or further away from the diaphragm 200, thus also putting the diaphragm 200 in a tensioned or relaxed state.

[0097] In this embodiment, the film supply mechanism 20 further includes a stamping assembly 24. The stamping assembly 24 is disposed between the first support plate 112 and the second support plate 113 of the frame 11 and is located on the moving path of the film 200. The stamping assembly 24 is used to punch and perforate the film 200 so that the hole structure on the film 200 can avoid the parts of the product 300 that do not need to be covered with film, thereby improving the versatility of the film application device 100. Specifically, the stamping assembly 24 includes a support member 241 and a stamping member 242 disposed above the support member 241. The film 200 passes between the support member 241 and the stamping member 242. The stamping member 242 can move closer to or away from the support member 241. The stamping member 242 moves closer to the support member 241 to punch and perforate the film 200. The stamping component 242 can be a cylinder with a punch. Driven by the cylinder, the punch punches and perforates the film component 200. The support component 241 has a through hole to allow waste material punched off the film component 200 by the stamping component 242 to fall off. Thus, by providing the aforementioned stamping assembly 24, punching and perforating the film component 200 is achieved, improving the versatility of the film application device 100.

[0098] Furthermore, the stamping assembly 24 also includes a mounting frame 243 and a stamping base 244. The mounting frame 243 is connected between the first support plate 112 and the second support plate 113 of the frame 11. The stamping base 244 is connected to the mounting frame 243, and both the support member 241 and the stamping member 242 are connected to the stamping base 244. In this embodiment, the number of stamping base 244, support member 241, and stamping member 242 are all two and correspond one-to-one. The stamping base 244, support member 241, and stamping member 242 can be modularly arranged. Thus, by setting the mounting frame 243 and the stamping seat 244, the support member 241 and the stamping member 242 are installed between the first support plate 112 and the second support plate 113. Furthermore, by setting the mounting frame 243, the stamping assembly 24 can have multiple stamping seats 244, support members 241 and stamping members 242, enabling the stamping assembly 24 to stamp out more hole structures and further improve the versatility of the film application device 100.

[0099] In this embodiment, the film supply mechanism 20 further includes a receiving component 25. The receiving component 25 is disposed between the first support plate 112 and the second support plate 113 of the frame 11 and located below the support member 241. The receiving component 25 is used to collect the film piece 200 that has been punched off by the stamping member 242, that is, the receiving component 25 collects the waste material punched off by the stamping member 242 on the film piece 200. The receiving component 25 can be a receiving box, and the receiving component 25 is connected to the first support plate 112 and the second support plate 113 respectively. In this way, by setting the above-mentioned receiving component 25, the film supply mechanism 20 can collect waste material, improve the cleanliness of the film application device 100, and prevent waste material from falling onto the product 300 and affecting the film application yield.

[0100] Please see Figure 5 and Figure 6 In this embodiment, the first film pressing mechanism 30 further includes a first driving member 32, which can be a cylinder. The first driving member 32 is disposed between the first support plate 112 and the second support plate 113 of the frame 11 and connected to the film pressing assembly 31. The first driving member 32 is used to drive the film pressing assembly 31 to move closer to or away from the conveyor belt 12. The first driving member 32 is inclined, that is, the first driving member 32 drives the film pressing assembly 31 to move obliquely. Specifically, the first film pressing mechanism 30 also includes a connecting seat 33, which is approximately L-shaped. The connecting seat 33 is connected to the first support plate 112, and the first driving member 32 is connected to the connecting seat 33. Thus, by setting the first driving member 32, the film pressing assembly 31 can move closer to or further away from the conveyor belt 12. By tilting the first driving member 32, the distance between the film pressing assembly 31 and the film pressing roller shaft 41 is closer, so that the film pressing roller shaft 41 can press against the connected film 200 and product 300 more quickly. By setting the connecting seat 33, the first film pressing mechanism 30 is set on the frame 11.

[0101] In this embodiment, the film pressing assembly 31 includes a connecting plate 311, a connecting shaft 312, a pressure plate 313, a base plate 314, a guide member 315, an elastic member 316, a receiving roller shaft 317, and a pressing roller shaft 318. There are two connecting plates 311, which are arranged opposite to each other. The connecting shaft 312 connects the two connecting plates 311 and is connected to the first driving member 32. The pressure plate 313 connects the two connecting plates 311. The base plate 314 is connected to the bottom of the two connecting plates 311, and is located below the pressure plate 313 with a gap between them. The base plate 314 is generally hollow. The guide member 315 movably passes through one of the connecting plates 311 and is fixedly connected to the base plate 314. The elastic member 316 can be a spring. The support component 316 is sleeved on the guide component 315 and located on the side of the connecting plate 311 away from the bottom plate 314. The receiving roller shaft 317 is rotatably disposed between the two connecting plates 311 and located on one side of the pressure plate 313. The pressing roller shaft 318 is rotatably disposed between the two connecting plates 311 and located on the other side of the pressure plate 313. The film component 200 passes through the receiving roller shaft 317, the gap between the pressure plate 313 and the bottom plate 314, and the pressing roller shaft 318 in sequence. The end of the pressure plate 313 and the bottom plate 314 near the pressing roller shaft 318 is adapted to the pressing roller shaft 318. Thus, after passing through the film supply mechanism 20, the film component 200 sequentially passes through the receiving roller 317, the gap between the pressure plate 313 and the base plate 314, and the pressing roller 318, with the film component 200 protruding from the pressing roller 318. The film pressing assembly 31 moves along with the film component 200 closer to the conveyor belt 12. Since the film pressing assembly 31 moves at an angle, the pressing roller 318 in the film pressing assembly 31 abuts against the product 300, thereby pressing the film component 200 below the pressing roller 318 onto the product 300, achieving the bonding between the film component 200 and the product. The connection between the film element 200 and the product 300 is achieved when the product 300 moves under the drive of the conveyor belt 12. The film element 200 moves along with the product 300 and continuously adheres to the product 300 under the pressure of the pressing roller shaft 318, thus achieving the connection between the film element 200 and the product 300. The gap between the pressure plate 313 and the base plate 314 can vary due to the guidance of the guide element 315 and the elasticity of the elastic element 316, providing space for the film element 200 to move and preventing it from being pulled apart. In this embodiment, the guide element 315 is approximately T-shaped, and there are four guide elements 315 and four elastic elements 316, each corresponding to one another. Each connecting plate 311 is provided with two guide elements 315 and two elastic elements 316.

[0102] Furthermore, the base plate 314 has multiple spaced clearance grooves 3141 on the side facing the pressure plate 313. By creating multiple clearance grooves 3141 on the base plate 314, the contact area between the base plate 314 and the membrane 200 is reduced, thereby reducing the friction between them and ensuring smooth movement of the membrane 200. Additionally, when the membrane 200 is coated with an adhesive, the side of the membrane 200 with the adhesive contacts the base plate 314. By creating multiple clearance grooves 3141 on the base plate 314, the contact area between the base plate 314 and the membrane 200 is reduced, preventing adhesion between them and ensuring smooth movement and adhesion of the membrane 200.

[0103] Please see Figure 7 In this embodiment, the second film pressing mechanism 40 further includes a second driving member 42 and a mounting base 43. The second driving member 42 can be a cylinder. The second driving member 42 is disposed between the first support plate 112 and the second support plate 113 of the frame 11. The mounting base 43 is connected to the second driving member 42, and the film pressing roller shaft 41 is rotatably mounted on the mounting base 43. Specifically, the second film pressing mechanism 40 also includes a mounting frame 44, which is connected to the second support plate 113, and the second driving member 42 is connected to the mounting frame 44. Thus, by setting the second driving member 42 and the mounting base 43, the film pressing roller shaft 41 is mounted on the frame 11. The second driving member 42 is inclined, allowing the film pressing roller shaft 41 to move obliquely, thereby making the distance between the film pressing roller shaft 41 and the film pressing assembly 31 closer. By setting the pressure roller shaft 41 to be rotatably mounted on the mounting base 43, the friction between the pressure roller shaft 41 and the connected film 200 and product 300 is reduced, ensuring the smooth movement of product 300.

[0104] Please see Figure 8In this embodiment of the application, the film cutting mechanism 50 further includes a film cutting drive 52, a film cutting slide rail 53, a film cutting slider 54, and a clamping member 55. Specifically, the film cutting mechanism 50 also includes a connecting frame 56. The connecting frame 56 is connected to the second support plate 113. The film-cutting drive 52 passes through the second support plate 113 and is connected to the connecting frame 56. The film-cutting drive 52 can be a cylinder. The film-cutting drive 52 is mounted on the second support plate 113 of the frame 11 via the connecting frame 56. One end of the film-cutting slide rail 53 is mounted on the first support plate 112 of the frame 11. The film-cutting slider 54 is slidably mounted on the film-cutting slide rail 53. The clamping member 55 is connected to the film-cutting slider 54 and to the film-cutting drive 52. The cutting member 51 is connected to the clamping member 55. The film-cutting drive 52 drives the clamping member 55 and the film-cutting slider 54 to slide along the film-cutting slide rail 53. The clamping member 55 drives the cutting member 51 to move, so that the cutting member 51 moves to cut the film 200. The cutting member 51 can be a blade. The angle of the cutting member 51 on the clamping member 55 can be adjusted to suit different cutting requirements. Understandably, the film cutting mechanism 50 may also include a slide rail seat 57, which is connected to the first support plate 112. A film cutting slide rail 53 is disposed on the slide rail seat 57, allowing the film cutting slide rail 53 to connect with the first support plate 112. The film cutting slide rail 53 can be integrally formed with the slide rail seat 57. Thus, by configuring the specific structure of the film cutting mechanism 50 described above, the cutting member 51 can move to cut the film member 200.

[0105] Please continue reading Figure 1 and Figure 2In this embodiment of the application, the film-applying device 100 further includes a flat pressing mechanism 60, which includes a first flat pressing roller shaft 61, a second flat pressing roller shaft 62, and a third flat pressing roller shaft 63. The first flat pressing roller shaft 61, the second flat pressing roller shaft 62, and the third flat pressing roller shaft 63 are all rotatably disposed between the first support plate 112 and the second support plate 113 of the frame 11 and are all located above the conveyor belt 12. The first flat pressing roller shaft 61 is located on the side of the film pressing assembly 31 away from the film pressing roller shaft 41, the second flat pressing roller shaft 62 is located on the side of the film pressing roller shaft 41 away from the film pressing assembly 31, and the third flat pressing roller shaft 63 is located on the side of the second flat pressing roller shaft 62 away from the film pressing roller shaft 41. The distance between the first flat pressing roller shaft 61 and the conveyor belt 12 and the distance between the second flat pressing roller shaft 62 and the conveyor belt 12 are equal and both are less than the distance between the third flat pressing roller shaft 63 and the conveyor belt 12. Thus, by setting the first flat pressure roller 61, the second flat pressure roller 62, and the third flat pressure roller 63 as described above, the first flat pressure roller 61 is used to abut against the product 300 to filter out impurities on the product 300 and ensure the cleanliness of the product 300. The first flat pressure roller 61 can be an object with electrostatic adsorption to adsorb dust and other substances on the product 300. The second flat pressure roller 62 is used to abut against the connected membrane 200 and the product 300 to ensure a tight fit between the membrane 200 and the product 300. The third flat pressure roller 63 is used to limit the product 300 after it is connected to the membrane 200 to prevent the product 300 from detaching from the conveyor belt 12.

[0106] Understandably, in this embodiment of the application, the number of first flat pressure rollers 61 can be two, the number of second flat pressure rollers 62 can be one, and the number of third flat pressure rollers 63 can be two. In other embodiments, the number of first flat pressure rollers 61, second flat pressure rollers 62, and third flat pressure rollers 63 can be more or less, depending on the actual situation.

[0107] The film-applying device 100 provided in this embodiment of the application, through the cooperation of the transmission mechanism 10, the film supply mechanism 20, the first film pressing mechanism 30, the second film pressing mechanism 40, and the film cutting mechanism 50, achieves mechanized operations for product 300 transmission, film supply to film 200, film pressing connection, film pressing and bonding, and film cutting of film 200. This effectively replaces manual film application, reduces labor costs, and improves film application efficiency and production capacity. Because of the mechanized operation, standardized film application is achieved, reducing errors caused by manual film application and improving the bonding accuracy of film 200. Furthermore, the pressure roller 41 of the second film pressing mechanism 40 presses against the connected film 200 and product 300, expelling air bubbles between the film 200 and product 300 and improving the film application yield. The film-applying device 100 provided in this embodiment of the application further ensures the cleanliness of product 300 by setting a flat pressure mechanism 60, further improving the bonding yield between product 300 and film 200.
