[0090] The carrying mechanism 10 includes a first shell 11 and a carrying component 12. The first shell 11 is a hollow structure and its upper side is an open structure. The carrying component 12 is arranged in the first shell 11 and is used to carry the workpiece to be film-coated, wherein the carrying component 12 can be adapted to carry the workpiece.

[0091] The film sticking mechanism 20 is disposed above the supporting mechanism 10. The film sticking mechanism 20 includes a power member 21, a mounting seat 22, a second housing 23, a driving assembly 24 and a suction member 25 (see Figure 5), the power member 21 is connected to the mounting seat 22, the second shell 23 is a hollow structure and its lower side is an open structure, the driving component 24 is arranged on the mounting seat 22 and the output end of the driving component 24 is passed through the second shell 23, the suction member 25 is arranged in the second shell 23 and connected to the output end of the driving component 24, the suction member 25 is used to communicate with an external vacuum device (not shown) for sucking the film, the power member 21 is used to drive the mounting seat 22, the second shell 23, the driving component 24 and the suction member 25 to move close to the first shell 11, so that the second shell 23 is connected to the first shell 11 to form a closed space, wherein the first shell 11 or the second shell 23 is connected to the external vacuum device to evacuate the closed space, and the driving component 24 is used to drive the suction member 25 to move close to the bearing component 12, so that the film on the suction member 25 fits on the workpiece on the bearing component 12 under a vacuum or negative pressure environment.

[0092] When the film pasting device 100 is pasting a film, the workpiece to be pasted with a film is placed on the bearing assembly 12 of the bearing mechanism 10, the suction piece 25 of the film pasting mechanism 20 sucks the film piece, and the power piece 21 drives the mounting seat 22, the second shell 23, the driving assembly 24, the suction piece 25 and the film piece to move close to the first shell 11, so that the second shell 23 is connected to the first shell 11 to form a closed space, and the closed space is evacuated by an external vacuum device, so that the closed space is a vacuum or negative pressure environment, for example, the pressure value in the vacuum or negative pressure environment is -30Kpa, and after the closed space is evacuated and the vacuum degree or negative pressure value reaches a threshold value, the driving assembly 24 drives the suction piece 25 to move the film piece ... suction piece 25 is driven by the power piece 21 to move the second shell 23 and the first shell 11 to move the second shell 23 and the first shell 11 to move the second shell 23 and the first shell 11 to move the second shell 23 and the first shell 11 to move the second shell 23 and the first shell 11 to move the second shell 23 and the first shell 11 to move the second shell 23 and the first shell 11 to move the second shell 23 and the first 5 and the film member move close to the workpiece on the carrier component 12, so that the film member fits on the workpiece under vacuum or negative pressure environment, and the driving component 24 continuously applies force to the suction member 25, so that the film member can be kept under pressure on the workpiece, for example, the pressure holding time is 2s. After the pressure holding is completed, the external vacuum device breaks the vacuum of the closed space, so that the closed space returns to the atmospheric pressure environment, and the driving component 24 drives the suction member 25 to move away from the carrier component 12 to the original position, and the power member 21 drives the mounting seat 22, the second shell 23, the driving component 24 and the suction member 25 to move to the original position, and the workpiece after film sticking is removed from the carrier component 12, thereby realizing the bubble-free film sticking operation on the workpiece.

[0093] It can be understood that the supporting mechanism 10 can be connected to an external moving module (not shown in the figure), which drives the supporting mechanism 10 to move away from the film-sticking mechanism 20 above it to load and unload materials. The power part 21 of the film-sticking mechanism 20 can also be connected to another external moving module (not shown in the figure), which drives the film-sticking mechanism 20 to move away from the supporting mechanism 10 below it so that the suction part 25 sucks the film, thereby improving the automation of the film-sticking device 100.

[0094] Please refer to Figure 3In this embodiment, the film sticking device 100 further includes a transparent member 30, which can be made of transparent glass, transparent plastic, etc. The transparent member 30 is arranged on the first shell 11, wherein an observation hole 111 is provided on the first shell 11, and the transparent member 30 covers the observation hole 111. In order to improve the sealing between the transparent member 30 and the first shell 11, a sealing ring 31 is also arranged between the transparent member 30 and the first shell 11. In this way, by arranging the transparent member 30 on the first shell 11, it is convenient to observe the film sticking operation in the closed space, and by arranging the sealing ring 31, the sealing between the transparent member 30 and the first shell 11 is improved to avoid air leakage in the closed space. It can be understood that in other embodiments, the transparent member 30 can also be arranged on the second shell 23.

[0095] In this embodiment, the film sticking device 100 further includes a barometer 40, which is disposed on the first housing 11 and located on one side of the transparent member 30. The barometer 40 is used to display the air pressure value in the enclosed space. Thus, by providing the above-mentioned barometer 40, the air pressure value in the enclosed space can be observed intuitively. It can be understood that in other embodiments, the barometer 40 can also be disposed on the second housing 23.

[0097] In this embodiment, the support mechanism 10 further includes a negative pressure connecting pipe 141, one end of which is connected to the first shell 11, and the other end of which is used to connect to an external vacuum device. In this way, by providing the above-mentioned negative pressure connecting pipe 141, the first shell 11 is connected to the external vacuum device, so as to facilitate vacuuming the enclosed space. It can be understood that the negative pressure connecting pipe 141 can also be connected to the second shell 23.

[0098] In this embodiment, the bearing mechanism 10 also includes a support frame 15, a calibration component 16, a calibration rod 17 and a closed bellows 18. The support frame 15 is roughly a U-shaped structure. The support frame 15 is arranged below the first shell 11 and connected to the first shell 11. The calibration component 16 is arranged in the support frame 15 and is located below the first shell 11. One end of the calibration rod 17 is connected to the calibration component 16, and the other end of the calibration rod 17 is movable through the first shell 11 to be connected to the bearing component 12 so that the bearing component 12 is relatively suspended in the first shell 11. The two ends of the closed bellows 18 are respectively connected to the first shell 11 and the calibration component 16 and are movably mounted on the calibration rod 17. The calibration component 16 drives the bearing component 12 to move through the calibration rod 17 to calibrate the position of the bearing component 12. Among them, the calibration component 16 can be a functional mechanism that drives the calibration rod 17 to perform multi-directional linear movement and rotation, such as a multi-axis module. The number of calibration rods 17 and closed bellows 18 are both four. Four movable holes 112 are opened on the lower side of the first shell 11. The four movable holes 112 correspond to the four calibration rods 17 one by one. The diameter of the movable hole 112 is larger than the diameter of the calibration rod 17. The calibration rod 17 is inserted into the corresponding movable hole 112, and the closed bellows 18 covers the corresponding movable hole 112. In this way, by setting the above-mentioned support frame 15, calibration component 16 and calibration rod 17, the calibration component 16 drives the calibration rod 17 to move, and the calibration rod 17 drives the bearing component 12 to move, so as to calibrate the position of the bearing component 12, which is beneficial to improve the fitting accuracy between the membrane and the workpiece; by setting the above-mentioned closed bellows 18, the closed space is sealed when the calibration rod 17 can be moved to avoid leakage in the closed space.

[0099] In this embodiment, the bearing mechanism 10 further includes a backlight source 19, which is disposed in the first housing 11 and below the bearing assembly 12. The backlight source 19 is used to emit light to cooperate with a CCD camera (not shown) to take a picture of the workpiece to be filmed, so as to obtain the position of the workpiece to be filmed, thereby improving the accuracy of the filming position; the light emitted by the backlight source 19 can also facilitate the user to clearly observe the filming operation in the closed space through the transparent member 30. There can be two backlight sources 19, and the two backlight sources 19 are arranged at intervals.

[0100] Please refer to Figure 4In this embodiment, the bearing assembly 12 includes a base 121, an actuating member 122, a first linkage member 123, a second linkage member 124, a first clamping block 125, a second clamping block 126 and a bearing plate 127. The actuating member 122 is arranged below the base 121 and is arranged in the first shell 11. It can be understood that the actuating member 122 can also be connected to the lower side of the base 121. The first linkage member 123 and the second linkage member 124 are both slidably and elastically arranged on the base 121, and the sliding directions of the first linkage member 123 and the second linkage member 124 are perpendicular to each other. The sliding and elasticity can be understood as the first linkage member 123 and the second linkage member 124 are both slidably arranged on the base 121 and can be reset by elastic force. The middle part of the first linkage member 123 and the end part of the second linkage member 124 are connected by inclined surfaces, the first clamping block 125 and the second clamping block 126 are respectively connected to the end of the first linkage member 123 and the other end of the second linkage member 124, the supporting plate 127 is used to adapt to the supporting workpiece, the supporting plate 127 is arranged on the base 121 and covers part of the first linkage member 123 and part of the second linkage member 124, the first clamping block 125 and the second clamping block 126 are respectively located on the adjacent two sides of the supporting plate 127, and the actuator 122 is used to drive the first linkage member 123 to move, so that the first linkage member 123 and the second linkage member 124 can respectively drive the first clamping block 125 and the second clamping block 126 to move away from the supporting plate 127 through inclined surface cooperation. Thus, when placing the workpiece, the actuator 122 drives the first linkage member 123 to move, so that the first clamping block 125 and the second clamping block 126 move away from the carrier plate 127 to leave a placement space. After the workpiece is placed on the carrier plate 127, the actuator 122 removes the force acting on the first linkage member 123, and the first linkage member 123 and the second linkage member 124 are reset under their respective elastic actions, so that the first clamping block 125 and the second clamping block 126 move close to the carrier plate 127 to cooperate with the carrier plate 127 to clamp the workpiece, thereby achieving the bearing and positioning of the workpiece. It can be understood that in other embodiments, the actuator 122 can also drive the second linkage member 124 to move.

[0101] In this embodiment, positioning pins 128 are respectively disposed on the other two adjacent sides of the carrier plate 127 . The positioning pins 128 are used to cooperate with the first clamping block 125 and the second clamping block 126 to position the workpiece.

[0102] In this embodiment, the actuating member 122 may be a cylinder, and the actuating member 122 drives the first linkage member 123 to move through the push member 1221 connected thereto, wherein the supporting mechanism 10 further includes an air source connector 142 (see Figure 3 ), an air source connector 142 is disposed on the first shell 11, one end of the air source connector 142 is used to communicate with an external air source device (not shown), and the other end of the air source connector 142 is used to communicate with the actuator 122 to provide an air source for the actuator 122.

[0103] In this embodiment, the base 121 includes a substrate 1211, a T-shaped member 1212, and an L-shaped member 1217. The substrate 1211 is connected to the calibration rod 17, and the actuating member 122 is connected to the lower side of the substrate 1211. The substrate 1211 is generally in the shape of the Chinese character "wang". The T-shaped member 1212 is embedded in the substrate 1211. The T-shaped member 1212 is provided with a first embedding groove 1213 and a second embedding groove 1214 that are perpendicular to each other and communicate with each other. A first embedding hole 1215 is provided at the bottom of the first embedding groove 1213, and a second embedding hole 1216 is provided at the bottom of the second embedding groove 1214. The first linkage member 123 and the second linkage member 124 are respectively slidably disposed in the first embedding groove 1213 and the second embedding groove 1214. The first linkage member 123 is provided with a first through hole 1231 corresponding to the first embedding hole 1215. A first reset member 1232 is disposed in the first through hole 1231 and the first embedding hole 1215. The second linkage member 124 is provided with a second through hole 1241 corresponding to the second embedding hole 1216. A second reset member 1242 is disposed in the second through hole 1241 and the first through hole 1231. The L-shaped member 1217 is connected to the T-shaped member 1212 and covers a part of the first linkage member 123 and a part of the second linkage member 124. Both the first reset member 1232 and the second reset member 1242 can be springs. When the first linkage member 123 and the second linkage member 124 move under the drive of the actuating member 122, they respectively compress the corresponding first reset member 1232 and second reset member 1242. When the actuating member 122 withdraws the acting force on the first linkage member 123, the first linkage member 123 and the second linkage member 124 respectively move under the elastic restoring acting forces of the corresponding first reset member 1232 and second reset member 1242. In addition, by providing the above-mentioned T-shaped member 1212 and L-shaped member 1217, the T-shaped member 1212, the first linkage member 123, the second linkage member 124, the first reset member 1232, the second reset member 1242, the first clamping block 125, the second clamping block 126, and the L-shaped member 1217 can be modularly arranged, so as to facilitate the assembly of the bearing assembly 12.

[0104] Please refer to Figure 5 , in this embodiment, the power member 21 can be a linear module. The mounting seat 22 includes a vertical plate 221, two side plates 222, and two cross plates 223. The power member 21 is connected to one side of the vertical plate 221. The two side plates 222 are spaced and connected to the other side of the vertical plate 221. The two cross plates 223 are respectively connected between the vertical plate 221 and the corresponding side plate 222. The vertical plate 221, the side plates 222, and the cross plates 223 are perpendicular to each other. Among them, the driving assembly 24 is disposed between the two side plates 222, and the second housing 23 is connected to the two cross plates 223.

[0105] In this embodiment, the film sticking mechanism 20 further includes a balancing assembly 26, which is connected between the second housing 23 and the horizontal plate 223 of the mounting seat 22. Specifically, the balancing assembly 26 includes a balancing sleeve 261, a balancing slide bar 262, and a balancing elastic member 263. The number of the balancing sleeve 261, the balancing slide bar 262, and the balancing elastic member 263 is four and one-to-one corresponding. Two balancing sleeves 261, two balancing slide bars 262, and two balancing elastic members 263 are arranged on each horizontal plate 223.

The balancing elastic member 263 is sleeved on the corresponding balancing slide bar 262 and abuts between the corresponding balancing sleeve 261 and the corresponding balancing slide bar 262. In this way, by setting the above-mentioned balancing component 26, when the actuator 122 drives the second shell 23 to connect with the first shell 11, the balance component 26 can ensure the balance of the first shell 11 and the second shell 23. In addition, by setting the balancing elastic member 263, soft contact can be achieved between the second shell 23 and the first shell 11 to avoid hard contact and scratches between the two.

[0106] In this embodiment, the driving assembly 24 includes a connecting plate 241, a movable plate 242, a driving member 243, a guide sleeve 244, a guide slide rod 245 and a connecting rod 246. The connecting rod 246 is arranged between the two side plates 222 of the mounting seat 22. The movable plate 242 is arranged on the side of the connecting plate 241 facing the second shell 23 and is spaced from the connecting plate 241. The driving member 243 can be a linear cylinder. The driving member 243 is arranged on the connecting plate 241 and the output end of the driving member 243 is connected to the movable plate 242. The guide sleeve 244 is provided on the connecting plate 241. There are four sleeves 244 and four guide slide rods 245, which are arranged in one-to-one correspondence. The guide sleeve 244 is arranged on the side of the connecting plate 241 facing the movable plate 242. One end of the guide slide rod 245 is connected to the movable plate 242, and the other end of the guide slide rod 245 is slidably passed through the corresponding guide sleeve 244. There are four connecting rods 246, one end of the connecting rod 246 is connected to the side of the movable plate 242 away from the connecting plate 241, and the other end of the connecting rod 246 is passed through the second shell 23 to be connected to the suction member 25. In this way, by setting the specific structure of the above-mentioned driving component 24, the driving member 243 drives the movable plate 242 to move, the movable plate 242 drives the connecting rod 246 to move, and the connecting rod 246 is slidably penetrated into the second shell 23 to drive the suction member 25 to move, so that the suction member 25 moves closer to or away from the supporting component 12. In addition, through the cooperation of the guide sleeve 244 and the guide slide rod 245, the movement accuracy of the connecting rod 246 and the suction member 25 is guaranteed, thereby ensuring the fitting accuracy of the membrane.

[0107] In this embodiment, the driving assembly 24 also includes a sealing bellows 247, a sealing sleeve 248 and a sealing elastic member 249. The number of the sealing bellows 247, the sealing sleeve 248 and the sealing elastic member 249 are all four, and correspond one to one with the four connecting rods 246. The two ends of the sealing bellows 247 are respectively connected to the movable plate 242 and the second shell 23. The sealing sleeve 248 is connected to the side of the second shell 23 facing the movable plate 242 and is located in the corresponding sealing bellows 247. The other end of the connecting rod 246 is slidably penetrated into the corresponding sealing sleeve 248 and is located in the corresponding sealing bellows 247. The sealing elastic member 249 can be a spring or an elastic cylindrical object. The sealing elastic member 249 is sleeved on the corresponding connecting rod 246 and abuts between the movable plate 242 and the corresponding sealing sleeve 248. In this way, by providing the above-mentioned sealing bellows 247, sealing sleeve 248 and sealing elastic member 249, on the one hand, through the sealing elastic member 249, the suction member 25 can be flexibly contacted with the workpiece on the supporting component 12 and the elastic force of the sealing elastic member 249 can apply pressure to the membrane member, thereby maintaining the pressure of the membrane member. On the second hand, through the sealing bellows 247, air leakage in the closed space can be avoided.

[0108] In this embodiment, the film-laminating mechanism 20 further includes a pressure sensing member 27, which is connected between the suction member 25 and the connecting rod 246 of the driving assembly 24 and is located in the second housing 23. Specifically, the pressure sensing member 27 is connected to the connecting rod 246 through a receiving plate 271, and the pressure sensing member 27 is used to sense the pressure exerted on the suction member 25. Thus, by providing the above-mentioned pressure sensing member 27, when the suction member 25 drives the film to contact the workpiece, the pressure sensing member 27 can sense the pressure exerted on the suction member 25. When the pressure value sensed by the pressure sensing member 27 reaches a preset value, the driving assembly 24 stops driving the suction member 25 to move and maintains the pressure for a preset time, thereby achieving pressure-maintaining laminating of the film and avoiding excessive squeezing of the workpiece to cause defects in the workpiece.

[0109] In this embodiment, the film sticking mechanism 20 also includes a negative pressure connector 28, which is arranged on the second shell 23. One end of the negative pressure connector 28 is used to connect with an external negative pressure device, and the other end of the negative pressure connector 28 is used to connect with the suction member 25, so that the suction member 25 can generate negative pressure under the action of the external negative pressure device and absorb the film.

[0110] The film pasting device 100 provided in this embodiment, through the cooperation between the supporting mechanism 10 and the film pasting mechanism 20, allows the film to be pasted to the workpiece in a vacuum or negative pressure environment. Since there is very little gas in the sealed cavity in a vacuum or negative pressure environment, there will be no bubbles when the film is pasted to the workpiece, so that bubble-free film pasting on the workpiece is achieved, meeting the film pasting requirements. In addition, when pasting a film on a non-planar structure workpiece, since only the film needs to be pressed to fit on the workpiece, compared with the rolling film pasting method, the film pasting device 100 can avoid the protrusions and other structures on the non-planar structure workpiece, and the film pasting device 100 has strong versatility, high film pasting accuracy, and high film pasting efficiency.
