Description

Technical Field

[0001] The present application relates to the technical field of protective film stripping, and in particular to a device for stripping protective film of an optical film. Background Art

[0002] In backlight products, when the optical film material is received, it is usually provided with upper and lower protective films to prevent the optical film from being scratched or damaged by external forces. In automated equipment, the upper and lower protective films of the optical film must usually be peeled off before the optical film material can be assembled into the product. The upper and lower protective films of the optical film are tightly attached to the optical film when they are received. When the optical film is received, it is a piece-by-piece material. The workload of manually tearing off the protective film is relatively large and cannot meet the requirements of automated production operations.

[0003] Regarding the above-mentioned related technologies, there are defects such as manually tearing off the upper and lower protective films, resulting in low production efficiency and failure to meet the requirements of automated production. Utility Model Content

[0004] In order to improve the defects of low production efficiency and failure to meet automated production requirements caused by manually tearing off the protective film, the present application provides an optical film protective film peeling device.

After being squeezed by the dust removal component, the tape and the protective film are tightly adhered together, the upper material receiving component pulls the upper tape, and the lower material receiving component pulls the lower tape to drive it through the slitting knife component to slit the optical film material. Since the viscosity of the tape is greater than the viscosity of the optical film material protective film, the protective film will be stuck to the tape. With the setting of the upper tape and the lower tape, the optical film protective film stripping device can automatically tear off the protective film on the upper and lower sides of the optical film, thereby improving production efficiency and meeting the requirements of automated production.

[0014] Optionally, the waste collecting assembly includes an upper waste collecting piece and a lower waste collecting piece, the upper waste collecting piece is connected to the fuselage and is located obliquely above the upper tape piece, the lower waste collecting piece is connected to the fuselage and is located obliquely below the lower tape piece, the upper waste collecting piece and the lower waste collecting piece both include a third inflatable shaft, and the third inflatable shaft is connected to the waste motor power.

[0019] By adopting the above technical scheme, since the first dust removal roller and the second dust removal roller are sticky, the dust on the optical film passing through the first dust removal roller and the second dust removal roller can be stuck, and as the first dust removal roller and the second dust removal roller rotate, since the stickiness of the first sticky tape and the second sticky tape is much greater than that of the first dust removal roller and the second dust removal roller, the dust is transferred to the first sticky tape and the second sticky tape, and the first sticky tape and the second sticky tape firmly stick to the dust so that the dust will not fall off, and after using it for a period of time, the first sticky tape and the second sticky tape are torn off, and the first telescopic member and the second telescopic member can be disassembled and assembled without the aid of any tools.

The first power transmission component drives the driving wheel to rotate, and the driving wheel contacts the passive wheel and transmits power to the passive wheel.

[0022] Optionally, the first power transmission assembly includes a material receiving motor and a first gear, the output end of the material receiving motor is connected to the first gear, and a transmission chain is provided between the first gear and the driving wheel.

[0023] By adopting the above technical solution, the material receiving motor drives the first gear to rotate, and the first gear drives the driving wheel to rotate through the transmission belt, thereby realizing the rotation of the driving wheels of the upper material receiving component and the lower material receiving component.

[0024] Optionally, the dust removal support frame includes a pressing plate, a dust removal pressing cylinder is connected above the pressing plate, and the first dust removal roller is dynamically connected to the first gear.

[0026] Optionally, the air inlets of the first inflatable shaft, the second inflatable shaft, and the third inflatable shaft are all connected with a rotary joint, and the first inflatable shaft and the second inflatable shaft are connected to the damper via a transmission belt.

[0031] By adopting the above technical solution, the passive wheel clamping cylinder can clamp the passive wheel. By controlling the passive wheel clamping cylinder, the clamping force between the active wheel and the passive wheel can be adjusted. The clamping force is the tensioning force of the upper tape and the lower tape to tear the protective film. The tensioning force of the upper tape and the lower tape can be adjusted by adjusting the passive wheel clamping cylinder.

[0032] In summary, the beneficial technical effect of the present application is: the optical film protective film stripping device can be equipped with upper and lower layers of tape, the upper tape sticks to the upper protective film of the optical film material; the lower tape sticks to the lower protective film of the optical film material. After being squeezed by the first dust removal roller and the second dust removal roller, the tape and the protective film are tightly adhered together, the upper material receiving component pulls the upper tape, and the lower material receiving component pulls the lower tape to drive it through the cutting knife assembly to cut out the optical film material. Since the viscosity of the tape is greater than the viscosity of the optical film material protective film, the protective film will be stuck to the tape.

[0038] The following is combined with Figure 1-4 This application is described in further detail.

[0039] The present application discloses an optical film protective film peeling device. Figure 1 The optical film protective film peeling device includes: a body 100, a tape assembly, a dust removal assembly 300, a material receiving assembly 400, a waste collection assembly 500, and a slitting knife assembly 600. The tape assembly, the waste collection assembly 500, the dust removal assembly 300, and the slitting knife assembly 600 are arranged in the upstream to downstream direction of the body 100.

[0040] Reference Figure 1 The body 100 includes a support plate 110, and the tape assembly includes an upper tape member 210 and a lower tape member 220. The upper tape member 210 is arranged above the support plate 110, and the lower tape member 220 is arranged below the support plate 110. The upper tape member 210 includes an upper tape and a first inflatable shaft 212, and the lower tape member 220 includes a lower tape and a second inflatable shaft 221. The first inflatable shaft 212 and the second inflatable shaft 221 are arranged on the body 100, the upper tape is installed on the first inflatable shaft 212, and the lower tape is installed on the second inflatable shaft 221.

[0041] Reference Figure 1 , Figure 4The dust removal assembly 300 is connected to the fuselage 100 and is located downstream of the support plate 110. The dust removal assembly 300 includes a dust removal support frame 310, which is arranged on the fuselage 100 and is located downstream of the support plate 110. The dust removal support frame 310 includes a first connecting plate and a second connecting plate, and the first connecting plate and the second connecting plate are provided with a first connecting port and a second connecting port at intervals from top to bottom, and the first connecting port and the second connecting port are provided with a first connecting seat and a second connecting seat respectively. The dust removal support frame 310 is provided with a first telescopic member 311 and a second telescopic member 312 at intervals from top to bottom, and the first telescopic member 311 and the second telescopic member 312 are provided on the first connecting seat and the second connecting seat respectively, and the first telescopic member 311 and the second telescopic member 312 can be disassembled and assembled without the aid of any tools.

[0042] The first telescopic member 311 and the second telescopic member 312 are provided with a first dust-removing tape 320 and a second dust-removing tape 321, respectively. The dust-removing support frame 310 is provided with a first dust-removing roller 330 and a second dust-removing roller 331 upstream of the first telescopic member 311 and the second telescopic member 312, respectively. The first dust-removing roller 330 is in contact with the first sticky tape 320, and the second dust-removing roller 331 is in contact with the second sticky tape 321. The first dust-removing roller 330 and the second dust-removing roller 331 are sticky. The roller 331 can stick to the fine dust on the protective film of the optical film passing between the first dust removal roller 330 and the second dust removal roller 331. The viscosity of the first sticky tape 320 and the second sticky tape 321 is greater than that of the first dust removal roller 330 and the second dust removal roller 331. During operation, the dust on the first dust removal roller 330 and the second dust removal roller 331 is transferred to the first sticky tape 320 and the second sticky tape 321 without falling off, effectively preventing the dust on the tape and the protective film from falling on the optical film material and the surrounding environment.

[0043] The dust removal support frame 310 includes a pressing plate 313, a second dust removal roller 331 is connected to the pressing plate 313, a dust removal pressing cylinder 314 is connected above the pressing plate 313, and the first dust removal roller 330 is connected to the first gear 416. The dust removal pressing cylinder 314 controls the movement of the pressing plate 313 to control the pressing force between the second dust removal roller 331 and the first dust removal roller 330. The dust removal pressing cylinder 314 presses the optical film material passing through the first dust removal roller 330 and the second dust removal roller 331, so that the roller transmission will not slip, thereby controlling the length of the material discharged.

[0044] The optical film protective film stripping device also includes an ion fan system. Before the optical film material enters the second dust removal roller 331 and the first dust removal roller 330, the static electricity of the optical film material is first eliminated to prevent dust from being easily adsorbed on the surface of the optical film material, which is beneficial to the adhesion of the second dust removal roller 331 and the first dust removal roller 330. After the optical film material is discharged, a large amount of static electricity will be generated due to the friction with the first dust removal roller 330 and the second dust removal roller 331. After the material is discharged, the static electricity is eliminated by the static electricity elimination rod at the rear to prevent the adsorption of dust.

[0045] The material receiving assembly 400 includes an upper material receiving component 410 and a lower material receiving component 420. The upper material receiving component 410 is connected to the fuselage 100 and is located obliquely above the dust removal assembly 300. The lower material receiving component 420 is connected to the fuselage 100 and is located obliquely below the dust removal assembly 300. The upper material receiving component 410 and the lower material receiving component 420 both include a material receiving support frame 411, a driving wheel 412, and a driven wheel 413. The driving wheel 412 and the driven wheel 413 are arranged in the material receiving support frame 411 at intervals. The material receiving support frame 411 includes a pressing plate, the driven wheel 413 is connected to the pressing plate, and the driving wheel 412 is connected to the first power transmission assembly 414. The material receiving support frame 411 is provided with a sensor 417 and a driven wheel pressing cylinder 418. The passive wheel pressing cylinder 418 is connected to the pressing plate. The film tearing power of the upper tape is determined by the pressing force between the active wheel 412 and the passive wheel 413 of the upper material receiving component 410, and the film tearing power of the lower tape is determined by the pressing force between the active wheel 412 and the passive wheel 413 of the lower material receiving component 420. The passive wheel pressing cylinder 418 can adjust and control the pressing force between the active wheel 412 and the passive wheel 413. The fuselage 100 includes a passive wheel regulating valve, and the pressing force between the active wheel 412 and the passive wheel 413 can be controlled by the passive wheel regulating valve, thereby controlling the film tearing power of the upper tape and the lower tape.

[0046] The waste collection assembly 500 includes an upper waste collection member 510 and a lower waste collection member 520. The upper waste collection member 510 is connected to the fuselage 100 and is located obliquely above the upper tape member 210. The lower waste collection member 520 is connected to the fuselage 100 and is located obliquely below the lower tape member 220. The upper waste collection member 510 and the lower waste collection member 520 both include a third inflatable shaft 511. The third inflatable shaft 511 of the upper waste collection member 510 and the lower waste collection member 520 are respectively used to recover the upper tape and the lower tape torn off after passing through the scalpel assembly 600. The third inflatable shaft 511 of the upper waste collection member 510 is connected to the upper waste motor 530 through a chain drive, and the third inflatable shaft 511 of the lower waste collection member 520 is connected to the lower waste motor 530 through a chain drive. The waste motor 530 adopts a torque motor, and the output torque and speed of the waste motor 530 can be manually controlled without the need for other touch screen devices, which is convenient and cost-saving.

[0047] The cutter assembly 600 is arranged on the fuselage 100 and is located downstream of the dust removal assembly 300. The cutter assembly 600 includes an upper cutter and a lower cutter. The upper cutter and the lower cutter have similar structures and are mirror-imaged on the fuselage with respect to the support plate 110. The upper cutter includes a first bevel and a second bevel, and the lower cutter includes a third bevel and a fourth bevel. The optical film enters the cutter assembly 600 from the first bevel and the third bevel. When passing through the second bevel, due to the tension of the upper material receiving component 410, the upper tape of the optical film can move upward along the second bevel, and the upper protective film of the optical film is torn off. Similarly, when passing through the fourth bevel, due to the tension of the lower material receiving component 420, the lower tape of the optical film can move downward along the fourth bevel, and the lower protective film of the optical film is torn off. Since the upper and lower cutters are arranged in mirror images, the optical film protective film stripping device can tear off the upper and lower protective films of the optical film at the same time, greatly improving production efficiency. The upper tape after passing through the second bevel passes through the upper receiving component 410 to reach the upper waste collection component 510 for waste recycling. The lower tape after passing through the fourth bevel passes through the lower receiving component 420 to reach the lower waste collection component 520 for waste recycling.

[0048] The first power transmission assembly 414 includes a material receiving motor 415 and a first gear 416. The output end of the material receiving motor 415 is connected to the first gear 416. The first gear 416 and the driving wheel 412 of the upper material receiving member 410 and the first gear 416 and the driving wheel 412 of the lower material receiving member 420 are driven by two sets of identical chain drives. The driving wheels 412 of the upper material receiving member 410 and the driving wheels 412 of the lower material receiving member 420 rotate synchronously. The material receiving motor 415 adopts a servo motor, and the speed control of the servo motor is more precise.

[0049] The air inlets of the first inflatable shaft 212, the second inflatable shaft 221, and the third inflatable shaft 511 are all connected with a swivel joint 213, so that the rotation of the inflatable shaft will not affect the air path ventilation pipeline. The first inflatable shaft 212 and the second inflatable shaft 221 are connected to the damper 211 through a transmission chain. The design of the damper 211 ensures that the tape is always in a tensioned state under the inertial rotation.

[0050] The machine body 100 is provided with a manual control valve group 120, which is used to control the waste motor 530, the material receiving assembly 400, and the air shaft. The air shaft, the waste motor 530, the material receiving assembly 400, etc. can be controlled by the corresponding manual control valves to switch on and off and adjust the air pressure, and the torque motor can manually adjust the torque. Manual material replacement and waste removal can be quickly operated by controlling the corresponding mechanical valves, without the need for other control switches or touch screen operations, making the control relatively simple. A fault indicator light is also provided above the machine body 100 to indicate a fault.

[0051] The implementation principle of the optical film protective film peeling device of the embodiment of the present application is as follows: an upper tape and a lower tape are set, the upper tape adheres to the upper protective film of the optical film material, and the lower tape adheres to the lower protective film of the optical film material; after the rolling of the first dust removal roller 330 and the second dust removal roller 331, the tape and the protective film are tightly adhered together, and when passing through the cutter assembly 600, the upper material receiving component pulls the upper tape, and the lower material receiving component pulls the lower tape to cut out the optical film material. Since the viscosity of the tape is greater than the viscosity of the optical film protective film, the protective film will be stuck to the tape.

[0052] When the first dust removal roller 330 and the second dust removal roller 331 are rolling, since the first dust removal roller 330 and the second dust removal roller 331 are sticky, the first dust removal roller 330 and the second dust removal roller 331 can stick to the fine dust on the optical film protective film passing between the first dust removal roller 330 and the second dust removal roller 331. During operation, the dust on the first dust removal roller 330 and the second dust removal roller 331 is transferred to the first sticky tape 320 and the second sticky tape 321 without falling off, effectively preventing the dust on the tape and the protective film from falling on the optical film material and the surrounding environment.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
