[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," and "third" may explicitly or implicitly include one or more of that feature.

[0027] A preferred embodiment of this application, such as Figures 1 to 9 As shown, a laminating device includes a mounting bracket 1, a film roller 2, and a laminating mechanism; the laminating mechanism includes a vacuum assembly 3, a laminating assembly 5, and a rolling roller 4; the film roller 2 is mounted on the mounting bracket 1 and is used to hold the film; the rolling roller 4 is provided with a plurality of air hole groups 41, and the plurality of air hole groups 41 are arranged along the circumference of the rolling roller 4 on the outer surface of the rolling roller 4; the vacuum assembly 3 is used to suck away the air in the air hole groups 41, so that the air hole groups 41 become a vacuum state; the laminating assembly 5 is used to cover the film onto the board.

[0028] In this embodiment, the film is guided to the coating equipment via the film roller 2, and the guiding direction of the film in the coating equipment is as follows: Figure 1 As shown. Before lamination, the beginning of the film is clamped to the beginning of the substrate by hand or machine. Then, as the substrate moves, the rolling roller 4 rolls accordingly, thereby guiding the film onto the substrate. Further, as... Figure 2 As shown, the outer surface of the rolling roller 4 is provided with several groups of air holes 41. Each group of air holes 41 consists of several air holes 41 evenly spaced along the length of the rolling roller 4, and these groups of air holes 41 are evenly spaced along the circumference of the rolling roller 4. Furthermore, the air holes 41 are connected to the vacuum assembly 3, which removes air from the air holes, creating a vacuum and generating negative pressure within the air holes 41. This causes the rolling roller 4 to generate an adsorption force. Therefore, when the film is conveyed on the rolling roller 4, the rolling roller 4 pulls and adsorbs the film, thereby increasing the film's stretchability and reducing film overlap. Furthermore, because the rolling roller 4 continuously adsorbs the film, and the beginning of the film is always clamped to the beginning of the substrate, the film coating assembly 5 drives the rolling roller 4 downwards, pulling the film covering the substrate downwards, further stretching the film and reducing wrinkles. Finally, the film is cut by machine or manually, completing the coating process. Therefore, by connecting the vacuum assembly 3 with the pore group 41, the rolling roller 4 generates an adsorption force to ensure that the film opens; more preferably, by driving the rolling roller 4 up and down through the coating assembly 5, the film covering the board is pulled and stretched to reduce wrinkles and overlaps of the film and ensure the coating effect.

[0029] Specifically, the rolling roller 4 has several through exhaust channels 42 inside, which are arranged along the circumference of the rolling roller 4 and are not interconnected; the exhaust channels 42 are connected to the air hole group 41; the vacuum assembly 3 includes a suction fan 31 and a clamping sleeve 32; the clamping sleeve 32 is respectively located at both ends of the rolling roller 4; the clamping sleeve 32 has several circular holes 321 and several outlets. Air vent 322; a plurality of circular holes 321 are arranged circumferentially on one end face of the mounting sleeve 32, and the plurality of circular holes 321 are not interconnected with each other; a plurality of air outlet holes 322 are arranged circumferentially on the arc surface of the mounting sleeve 32, and the plurality of air outlet holes 322 are not interconnected with each other; the circular holes 321 and the air outlet holes 322 are connected; the circular holes 321 are connected to the exhaust channel 42; the suction fan 31 is used to draw air into the air outlet holes 322.

[0030] In this embodiment, during the suction process of the suction fan 31, gas is drawn from the air hole group 41 into the exhaust channel 42, then flows from the exhaust channel 42 into the circular hole 321, and finally is drawn out from the air outlet 322, thus realizing the suction process. Therefore, when the film covers the rolling roller 4, the gas in the exhaust channel 42 is drawn away, and the film also prevents gas from entering the exhaust channel 42, thereby creating a negative pressure in the covered exhaust channel 42. This causes the rolling roller 4 to pull and adhere to the film, thereby increasing the film's stretchability and reducing film overlap. It is worth noting that in other embodiments, the suction fan 31 can be other suction devices, such as a vacuum pump.

[0031] Furthermore, the vacuum assembly 3 also includes a connecting kit 33 and a suction pipe 34; the connecting kit 33 has a through-hole ventilation groove 331 inside; the connecting kit 33 is snapped onto the arc surface of the snap-fit ​​sleeve 32, and the ventilation groove 331 communicates with the air outlet 322; the suction pipe 34 is inserted inside the connecting kit 33, and the air inlet end of the suction pipe 34 communicates with the ventilation groove 331; the air outlet end of the suction pipe 34 communicates with the suction fan 31. Figure 4 As shown, the purpose of setting the suction pipe 34 and the ventilation groove 331 is to concentrate the suction force of the suction fan 31, thereby further ensuring that the gas in the exhaust channel 42 is drawn away, ensuring that the exhaust channel 42 maintains negative pressure, thereby ensuring the pulling and adsorption of the film by the rolling roller 4.

[0032] Preferably, the connecting kit 33 includes a locking sleeve 331 and an engaging kit 332; the locking sleeve 331 has a first connecting hole; the engaging kit 332 has a second connecting hole; the locking kit connects the first connecting hole and the second connecting hole through a connector, so that the engaging kit 332 engages with the arc surface of the mounting sleeve 32. Figure 6 As shown, the mounting process of the connecting kit 33 is as follows: First, the arc-shaped connecting surface of the engaging kit 332 is positioned on the arc-shaped surface of the engaging sleeve 32. Then, the connector passes through the first connecting hole and the second connector in sequence, so that the locking sleeve 331 exerts a downward pressing force on the engaging kit 332, thereby allowing the arc-shaped connecting surface of the engaging kit 332 to better clamp the arc-shaped connecting surface of the engaging sleeve 32. This design makes the connecting kit 33 simple and compact in structure, and reduces manufacturing costs.

[0033] Preferably, the clamping sleeve 32, the connecting kit 33, and the clamping sleeve 32 are all made of oil-based nylon sheet material or polytetrafluoroethylene material. Because parts made of these two materials have good wear resistance, the service life of the clamping sleeve 32, the connecting kit 33, and the clamping sleeve 32 is extended. Furthermore, they have good sealing properties, ensuring a vacuum effect.

[0034] Preferably, the coating assembly 5 includes a telescopic cylinder 51, a bearing seat 53, and a mounting plate 52; the telescopic cylinder 51 is hinged to the telescopic mounting bracket 1, and the telescopic drive end of the telescopic cylinder 51 can extend and retract in the vertical direction; the bearing seat 53 is mounted on the mounting bracket 1; one end of the mounting plate 52 is sleeved on the bearing seat 53, and the other end of the mounting plate 52 is hinged to the telescopic drive end of the telescopic cylinder 51, so that the telescopic drive end of the telescopic cylinder 51 can drive the mounting plate 52 to move up and down; the rolling roller 4 is sleeved on the mounting plate 52. Because one end of the mounting plate 52 is sleeved on the bearing seat 53 and the other end is hinged to the telescopic cylinder 51, when the telescopic cylinder 51 extends and retracts, it can drive the mounting plate 52 to move up and down around the bearing seat 53, and drive the rolling roller 4 mounted on the mounting plate 52 to move up and down, so as to tighten the covered film and ensure the coating quality.

[0035] Preferably, the mounting bracket 1 further includes a cutting assembly; the cutting assembly includes a cutting cylinder 6 and a cutting line; the telescopic drive end of the cutting cylinder 6 can extend and retract in the vertical direction; the cutting line is connected to the telescopic drive end of the cutting cylinder 6. When the coating assembly 5 drives the rolling roller 4 downward to tighten the film, the cutting cylinder 6 can drive the cutting line downward to quickly cut the film, causing the covered film to disconnect from the rolling roller 4, thereby quickly entering the coating process of the next board and accelerating the board production efficiency.

[0036] In actual manufacturing, there are many types of cutting wires used for cutting films. However, in this embodiment, the cutting wire is preferably made of iron wire or heating wire. Iron wire is preferred because of its high hardness, resulting in lower manufacturing costs. Heating wire, on the other hand, allows for high-temperature cutting, thus increasing cutting efficiency.

[0037] Preferably, it further includes a clamping assembly; the clamping assembly includes a clamping cylinder 71 and a clamping block 72; the telescopic drive end of the clamping cylinder 71 can extend and retract in the vertical direction; the clamping block 72 is mounted on the telescopic drive end of the clamping cylinder 71. Figure 7As shown, the pressing cylinder 71 drives the pressing block 72 to move downward, thereby pressing the film covering the plate. Therefore, when the coating assembly 5 drives the rolling roller 4 downward, the two ends of the film are pulled tight, thereby ensuring the film's opening degree, avoiding film overlap, and ensuring coating quality.

[0038] Preferably, the mounting bracket 1 further includes a rolling drive motor 81 and a transmission gearbox; the rolling drive end of the rolling drive motor 81 is connected to the transmission gearbox; the end of the rolling roller 4 is sleeved inside the transmission gearbox. Figure 8 As shown, the rolling drive end of the rolling drive motor 81 drives the gear in the transmission gearbox to rotate, which in turn drives the rolling roller 4 sleeved on the gear to rotate, so that the film can be guided from the film roll to the plate.

[0039] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
