For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0042] As Figure 2 shown, an automatic glass film pasting device according to an embodiment of the present invention includes a support frame 10, a transmission and placement mechanism 20, and a film pasting mechanism 30. The transmission and placement mechanism 20 is arranged on the support frame 10 and is used for transmitting and placing glass. The film pasting mechanism 30 is arranged above the transmission and placement mechanism 20. The film pasting mechanism 30 includes a plurality of film pasting heads 38 arranged side by side. The plurality of film pasting heads 38 can move up and down and horizontally, and simultaneously paste multiple film bodies 60 on the glass and cut the film bodies 60. The number of the film pasting mechanism 30 and the number of the film pasting heads 38 on each film pasting mechanism 30 are not specifically limited. In order to improve work efficiency, a plurality of film pasting mechanisms 30 can be set. The number of the film pasting heads 38 on each film pasting mechanism 30 can be specifically set according to the number of the film bodies 60. In this embodiment, two film pasting mechanisms 30 are simultaneously arranged above the transmission and placement mechanism 20 to respectively paste the film bodies 60 on both sides of the glass. Five film pasting heads 38 are arranged side by side on each film pasting mechanism 30, and the extra film pasting heads 38 can be used as reserved heads.

[0043] Specifically, as Figure 3 shown, the transmission and placement mechanism 20 includes a fixed plate platform 21 and a lifting conveyor belt 22. The lifting conveyor belt 22 is arranged between the fixed plate platforms 21 and can transmit and place the glass on the fixed plate platform 21. A positioning mechanism is arranged around the fixed plate platform 21 for positioning the glass, and a fixed suction cup 211 is arranged on the fixed plate platform 21 for fixing the glass.

[0044] In this embodiment, the fixed plate platform 21 is an optical fiber board with a split structure, and is fixed on the support frame 10 by the support rod 212. The lifting conveyor belt 22 is arranged between the split structures. A lifting cylinder 221 is provided at the bottom of the lifting conveyor belt 22, and the lifting cylinder 221 is fixed on the support frame 10 and can drive the lifting conveyor belt 22 to move up and down. The number of the lifting cylinders 221 is not specifically limited. To enable the stable lifting of the lifting conveyor belt 22, vertical guide shafts 222 are provided at the bottom of the lifting conveyor platform. The specific number of the guide shafts 222 is not limited. The guide shafts 222 are movably connected to the sleeves 223 relatively fixed on the support frame 10, and the guide shafts 222 can move up and down along the sleeves 223. The positioning mechanism includes a positioning cylinder 23, and the positioning cylinder 23 is fixed on the support frame 10. A positioning roller 231 is provided on the positioning cylinder 23, and the positioning cylinder 23 can drive the positioning roller 231 to move towards the glass. To facilitate the movement of the positioning roller 231 towards the glass and abut against the four sides of the glass, rectangular grooves are formed on the fixed plate platform 21 at positions opposite to the positioning rollers 231.

[0045] When transporting the glass, the lifting conveyor belt 22 is higher than the fixed plate platform 21. When the glass is transported above the fixed plate platform 21, the lifting conveyor belt 22 descends to a position lower than the fixed plate platform 21, so that the glass is placed on the fixed plate platform 21. The positioning cylinder 23 drives the positioning roller 231 to move towards the glass around the glass to abut and position the glass. After positioning, the fixed suction cup 211 adsorbs and fixes the glass.

[0046] Specifically, as Figure 4 、 Figure 5 and Figure 6 shown, a first driving device 32 is provided on the film applying mechanism 30. A second driving device 34 is connected to the first driving device 32 and can drive the second driving device 34 to move horizontally along the pasting track of the film body 60. A plurality of film applying heads 38 are arranged side by side on the second driving device 34 and can drive the plurality of film applying heads 38 to move up and down. A third driving device 382 is provided on each film applying head 38 and can drive the film applying head 38 to move horizontally along the side-by-side direction. The pasting track is perpendicular to the side-by-side direction.

[0047] In this embodiment, a first guide rail 40 is provided above the transmission and placement mechanism 20. The first guide rail 40 is fixed on the support frame 10 and is arranged along the pasting track of the film body 60. Two film pasting mechanisms 30 are arranged along the first guide rail 40 and are slidably connected to the first guide rail 40. Parallel to the first guide rail 40, a first rack 50 is fixed on the support frame 10. The film pasting mechanism 30 includes a support frame 31. On one side of the support frame 31, a first driving device 32 is installed, specifically a motor. A first driving gear 33 is connected to the first driving device 32. The first driving gear 33 is externally engaged with the first rack 50. The first driving device 32 can drive the first driving gear 33 to roll along the first rack 50, so that the film pasting mechanism 30 can move horizontally along the first guide rail 40, that is, move horizontally along the pasting track of the film body 60. A second driving device 34 is fixed in the middle of the support frame 31, specifically a lead screw structure. The lead screw structure is arranged vertically. A moving bracket 35 is connected to the moving nut of the lead screw structure and can drive the moving bracket 35 to move up and down. A plurality of film pasting heads 38 are arranged side by side on the moving bracket 35. The side-by-side direction of the film pasting heads 38 is perpendicular to the pasting track of the film body 60. A second guide rail 36 is horizontally fixed on the moving bracket 35 along the side-by-side direction. A plurality of film pasting heads 38 are slidably connected to the second guide rail 36. A second rack 37 is fixed on the moving bracket 35 and is arranged parallel to the second guide rail 36. A third driving device 382, specifically a motor, is fixed on the head connecting frame 381 of each film pasting head 38. A second driving gear is connected to the third driving device 382. The second driving gear is externally engaged with the second rack 37. The third driving device 382 can drive the second driving gear to roll along the second rack 37, so that each film pasting head 38 can move along the side-by-side direction, adjust the pasting spacing and position of the film body 60. The second driving gear is not shown in the figure.

[0048] Specifically, as Figure 7 , Figure 8 and Figure 9 shown, the film pasting head 38 includes a film releasing mechanism 384, a film feeding mechanism 385, a film pressing mechanism 386 and a film cutting mechanism 387. The film releasing mechanism 384, the film feeding mechanism 385, the film pressing mechanism 386 and the film cutting mechanism 387 are connected to the head connecting frame 381. The film feeding mechanism 385 is arranged below the film releasing mechanism 384. The film pressing mechanism 386 is arranged on one side of the film feeding mechanism 385. The film cutting mechanism 387 is arranged between the film feeding mechanism 385 and the film pressing mechanism 386. The film releasing mechanism 384 is used for releasing the film and conducting the film body 60, and conducting the film body 60 to the film feeding mechanism 385. The film feeding mechanism 385 is used for conveying the end of the film body 60 to the lower part of the film pressing mechanism 386. The film pressing mechanism 386 is used for pasting the film body 60 on the glass surface. The film cutting mechanism 387 is used for cutting the film body 60.

[0049] The first driving device 32 drives the film pasting head 38 to move horizontally along the pasting track, the third driving device 382 drives the film pasting head 38 to move horizontally along the side-by-side direction, the second driving device 34 drives the film pasting head 38 to move up and down. After moving the film pasting head 38 to the initial pasting position of the film body 60, the film feeding mechanism 385 conveys the end of the film body to the lower part of the film pressing mechanism 386, and the film pressing mechanism 386 pastes the film body on the glass surface. After the first driving device 32 drives the film pasting head 38 to move along the pasting track to complete the pasting of the entire film body 60, the film cutting mechanism 387 cuts off the film body 60.

[0050] The film feeding mechanism 384 includes a support roller 3841, a plurality of fixed guide wheels 3842 and a movable guide wheel 3843. The support roller 3841 is used to support the film body reel, and a plurality of fixed guide wheels 3842 are arranged at the bottom of the support roller 3841 for conducting the film body 60 to the film feeding mechanism 385. The movable guide wheel 3843 is arranged between the fixed guide wheels 3842, and the film body 60 can drive the movable guide wheel 3843 to move up and down during the conduction process.

[0051] In this embodiment, a support roller 3841 is installed on the top of the head connecting frame 381, and a film body reel is wound thereon. A feeding motor 3844 is connected to the support roller 3841 for driving the support roller 3841 to rotate to feed the film body 60. A conduction roller 3845 is installed below the support roller 3841, and a plurality of fixed guide wheels 3842 are rotatably connected below the conduction roller 3845 through a vertically arranged mounting plate 383, and the mounting plate 383 is fixed to the bottom of the head connecting frame 381. When the film body 60 is conducted by the conduction roller 3845 and the uppermost fixed guide wheel 3842, the film body 60 needs to be twisted according to the installation directions of the conduction roller 3845 and the fixed guide wheel 3842. A movable guide wheel 3843 is installed between the two fixed guide wheels 3842 in the middle position. A long hole is formed in the mounting plate 383 corresponding to the moving track of the movable guide wheel 3843, and the movable guide wheel 3843 can move up and down along the long hole. Since the diameter of the film body reel becomes smaller and smaller during the feeding process, if the support roller 3841 maintains the same rotation speed, it is easy to cause the film body 60 to be loose at the front and tight at the back during the conduction process. Therefore, it is necessary to adjust the rotation speed of the support roller 3841 to make the feeding of the film body 60 more stable. In order to prevent the film body 60 from being too loose or too tight during the feeding process and affecting the normal conduction, the movable guide wheel 3843 is provided. When the film body 60 becomes loose or tight during the conduction process, it will drive the movable guide wheel 3843 to move downward or upward. By detecting the height of the movable guide wheel 3843, the rotation speed of the support roller 3841 can be adjusted. During the process of the film body 60 becoming loose or tight, the movable guide wheel 3843 can also play a tensioning role to ensure the stable conduction of the film body 60.

[0052] To ensure the movement trajectory of the movable guide wheel 3843, a vertical guide rail 3846 is installed on the other side of the mounting plate 383. The movable guide wheel 3843 passes through the long hole and is slidably connected to the vertical guide rail 3846. To ensure the balance of the movable guide wheel 3843, a counterweight 3847 is installed at one end of the movable guide wheel 3843 away from the vertical guide rail 3846. To detect the height of the movable guide wheel 3843, an upper limit sensor 3848 and a lower limit sensor 3849 are fixed above and below the vertical guide rail 3846. When the movable guide wheel 3843 rises to the upper limit sensor 3848, the film body 60 becomes too tight. At this time, the rotation speed of the support roller 3841 is increased to speed up the film release. When the movable guide wheel 3843 drops to the lower limit sensor 3849, the film body 60 becomes too loose. At this time, the rotation speed of the support roller 3841 is decreased to slow down the film release.

[0053] To facilitate the conduction of the film body 60, the entire film feeding mechanism 385 is inclined, including a base 3851 and a guide plate 3852 arranged oppositely. One end of the guide plate 3852 close to the film pressing mechanism 386 extends out of the base 3851. Above the guide plate 3852, there is a film clamping cylinder 3853, which is fixedly connected to the base 3851 and is perpendicular to the base 3851 and the guide plate 3852. A through hole is provided at the position of the mounting plate 383 relative to the film feeding mechanism 385. One side of the base 3851 close to the through hole passes through the through hole and is connected to the film feeding cylinder 3854 fixed on the other side of the mounting plate 383. A groove is provided on one side of the guide plate 3852 close to the base 3851, forming a through groove gap with the base 3851. The film body 60 can pass through this gap and is in clearance fit with this gap. A through hole is provided at the position of the guide plate 3852 relative to the film clamping cylinder 3853. The film clamping cylinder 3853 can pass through the through hole and press on the film body 60 to clamp the film body 60. The film clamping cylinder 3853 clamps the film body 60. At the same time, the film releasing mechanism 384 releases the film and conducts the film body 60. When the film feeding cylinder 3854 extends, it can drive the film body 60 to move close to the film pressing mechanism 386 and convey the film body 60 to the lower part of the film pressing mechanism 386. After the film feeding is completed, the film clamping cylinder 3853 shortens and no longer clamps the film body 60, and the film feeding cylinder 3854 shortens and resets. The film body 60 can be normally conducted in the gap.

[0054] Since the film body 60 is relatively soft, the end part of the film body 60 is very easy to sag after passing through the gap between the guide plate 3852 and the base 3851, which is not convenient for placing it under the film pressing mechanism 386. An air inlet hole 3855 is provided on one side of the base 3851. By blowing air into the gap between the guide plate 3852 and the base 3851 through the air inlet hole 3855, when the gas blows out from the end close to the film pressing mechanism 386, the film body 60 can be placed along the guide plate 3852 and the end part will not sag, which is more convenient for the film feeding mechanism 385 to send the end part of the film body 60 to the lower part of the film pressing mechanism 386.

[0055] Preferably, as Figure 7 、 Figure 9 and Figure 10 shown, a heating mechanism 388 is provided below the film feeding mechanism 385. A hot air outlet 3881 is provided at one end of the heating mechanism 388 close to the film pressing mechanism 386. During the pasting process, the film body 60 is heated, making the pasting of the film body 60 more firm. In this embodiment, the heating mechanism 388 is fixed to the bottom of the mounting plate 383 and includes a heating chamber 3882. A hot air outlet 3881 is fixed at one end of the heating chamber 3882 close to the film pressing mechanism 386, and an air inlet 3883 is fixed at the other end.

[0056] Preferably, in order to more conveniently place the film body 60 along the guide plate 3852, a guide block 3884 is fixed above the hot air outlet 3881. The top of the guide block 3884 is an inclined guide surface. The guide surface is disposed opposite to one end of the guide plate 3852 extending out of the base 3851. A gap is formed between the guide surface and the guide plate 3852. The film body 60 can pass through the gap and is in clearance fit with the gap.

[0057] Specifically, the film pressing mechanism 386 includes a film pressing cylinder 3861 and a film pressing roller 3862. The film pressing roller 3862 is disposed on the film pressing cylinder 3861. The film pressing cylinder 3861 can drive the film pressing roller 3862 to move up and down. In this embodiment, the film pressing cylinder 3861 is vertically fixed to the bottom of the mounting plate 383. A film pressing roller 3862 is rotatably connected to the movable end of the film pressing cylinder 3861. When the film feeding mechanism 385 sends the end of the film body 60 below the film pressing roller 3862, the film pressing cylinder 3861 drives the film pressing roller 3862 to move downward, pressing the film body 60 on the glass surface. The first driving device 32 drives the film pasting head 38 to move along the pasting track of the film body 60 so that the film body 60 is laid along the pasting track. During the laying process, the film pressing roller 3862 rolls along the film body 60, pasting the film body 60 on the glass surface.

[0058] Specifically, the film cutting mechanism 387 includes a moving cylinder 3871. A shearing cylinder 3872 is provided on the moving cylinder 3871, which can drive the shearing cylinder 3872 to approach or move away from the film body 60. A pair of scissors 3873 is provided on the shearing cylinder 3872, which can drive the pair of scissors 3873 to open and close. In this embodiment, the moving cylinder 3871 is fixed to one side of the mounting plate 383 where the film feeding mechanism 385 and the film pressing mechanism 386 are not installed. The movable end of the moving cylinder 3871 is fixed with a vertically arranged shearing cylinder 3872 through a connecting bracket 3874. A pair of scissors 3873 is installed at the bottom of the shearing cylinder 3872, as Figure 9 and Figure 10As shown, the lower blade of the scissors 3873 is fixed to the bottom of the connecting bracket 3874, and the upper blade of the scissors 3873 is connected to the movable end of the shearing cylinder 3872, which can drive the upper blade of the scissors 3873 to move up and down, so that the scissors 3873 can open and close.

[0059] Preferably, as Figure 9 and Figure 10 shown, in order to prevent the film body 60 from being deflected during the film pasting process, a deviation prevention frame 389 is provided on one side of the film pressing mechanism 386 close to the film cutting mechanism 387. A deviation prevention groove 3891 is provided at the bottom of the deviation prevention frame 389, and the film body 60 can pass through the deviation prevention groove 3891. In this embodiment, the deviation prevention frame 389 is fixed to the bottom of the mounting plate 383. According to the conduction direction of the film body 60, an inclined deviation prevention groove 3891 is formed at the bottom of the deviation prevention frame 389. During the film pasting process, the deviation prevention groove 3891 can limit the film body 60.

[0060] Preferably, a visual inspection mechanism is provided above the film pasting mechanism 30 for detecting the pasting state of the reflective film. In this embodiment, the visual inspection module is specifically a camera, which is fixed to the top of the support frame 10 above the glass and is not shown in the figure. After the film pasting is completed, the film pasting mechanism 30 leaves above the glass, and the camera performs visual inspection. If it is qualified, the glass is conveyed to the next process by blanking. If it is unqualified, an alarm is given, and the specific unqualified position is reported, and the unqualified film body 60 is torn off and pasted again.

[0061] Workflow: The lifting conveyor belt 22 rises higher than the fixed plate platform 21, and the external transmission device conveys the glass to be pasted onto the lifting conveyor belt 22. When the glass is conveyed above the fixed plate platform 21, the lifting conveyor belt 22 descends to a position lower than the fixed plate platform 21, so that the glass is placed on the fixed plate platform 21. The positioning cylinder 23 drives the positioning roller 231 to move towards the glass around the glass to hold and position the glass. After positioning, the fixed suction cup 211 on the fixed plate platform 21 adsorbs and fixes the glass.

[0062] The first driving device 32 drives the film pasting head 38 to move horizontally along the pasting track, the third driving device 382 drives the film pasting head 38 to move horizontally along the side-by-side direction, and the second driving device 34 drives the film pasting head 38 to move up and down, moving the film pasting head 38 to the initial pasting position of the film body 60.

[0063] The film releasing mechanism 384 releases and conducts the film body 60. Meanwhile, after the feeding mechanism 385 passes the end of the film body 60 through the anti-deviation groove 3891 and conveys it to the lower part of the film pressing mechanism 386, the film pressing mechanism 386 presses the film body 60 on the glass surface. The clamping film cylinder 3853 shortens to release the film body 60, and the film feeding cylinder 3854 shortens to reset. The first driving device 32 drives the film pasting head 38 to move along the pasting track to complete the laying of the entire film body 60. During the laying process, the film pressing roller 3862 rolls along the film body 60 to paste the film body 60 on the glass surface. Meanwhile, the hot air outlet 3881 of the heating mechanism 388 heats the film body 60 to make the pasting of the film body 60 more firm. During the film pasting process, the anti-deviation groove 3891 can limit and prevent deviation of the film body 60. When the film body 60 is pasted, the clamping film cylinder 3853 extends through the guide plate 3852 to clamp the film body 60, and the film cutting mechanism 387 cuts off the film body 60.

[0064] In this embodiment, two groups of film pasting mechanisms 30 are provided, which are respectively responsible for pasting the film bodies 60 on both sides. After the film bodies 60 of the entire glass are pasted, the film pasting mechanism 30 leaves above the glass, and the visual inspection mechanism conducts visual inspection. If it is qualified, the glass is fed and transported to the next process. If it is unqualified, an alarm is given, the specific unqualified position is reported, and the unqualified film body 60 is torn off and pasted again.
