Description

Technical Field

[0001] The utility model relates to the technical field of film tearing, in particular to a film tearing auxiliary device and film tearing equipment. Background Art

[0002] Liquid crystal displays typically consist of multiple stacked glass substrates. To tightly bond these together, a cut glue is typically applied to one of the glass substrates. A corner lifter is then used to lift a corner of the protective film on the cut glue using an easy-tear sticker. The conveyor platform is then moved in the feed direction, tearing off the protective film and exposing another adhesive surface. Another glass substrate is then bonded, allowing the stacking of multiple glass substrates to be accomplished.

[0003] However, the current method is to use an easy-tear sticker to stick a corner of the protective film on the cut glue, and then move the conveying platform along the feeding direction to tear off the protective film. During the film tearing process, the film tearing mechanism will transfer the pulling force to the cut glue when tearing off the protective film, causing the cut glue to be separated from the glass substrate by force, thereby causing poor pulling and reducing product quality.

[0043] In order to improve the problem of poor glue pulling when tearing off the protective film of the cut glue adhered to the glass substrate, and to adapt to products of different specifications and sizes, this embodiment provides a film tearing auxiliary device, which is used to assist in tearing off the protective film on the to-be-torn piece, that is, the protective film on the cut glue on the glass substrate.

[0044] Figure 1 This is the assembly drawing of the film tearing auxiliary device. Figure 2 This is a schematic diagram of the structure of the rotating mechanism in the film tearing auxiliary device provided by the utility model. Figure 3 This is a structural diagram of the lifting mechanism in the film tearing auxiliary device provided by the utility model. Figure 4 This is a schematic diagram of the structure of the film tearing mechanism in the film tearing auxiliary device provided by the present invention. Figure 1-4As shown, the film tearing auxiliary device includes a rotating mechanism 1, a lifting mechanism 2 and a film tearing mechanism 3. The rotating mechanism 1 includes a turntable 11 and a rotating drive module 12. The rotating drive module 12 is used to drive the turntable 11 to rotate. The lifting mechanism 2 includes a lifting slider 21, a lifting slide rail 22 and a lifting drive module 23. The lifting slide rail 22 is connected to the turntable 11. The lifting slider 21 is slidably arranged on the lifting slide rail 22 along a first direction. The lifting drive module 23 is used to drive the lifting slider 21 to slide along the first direction. The film tearing mechanism 3 includes a mounting plate 31, a film tearing roller 32 and a pressure roller 33. The mounting plate 31 is connected to the lifting slider 21. The film tearing roller 32 is arranged on the side of the mounting plate 31 away from the to-be-torn piece 100 along the first direction. The pressure roller 33 is arranged on the side of the mounting plate 31 close to the to-be-torn piece 100 along the first direction. The pressure roller 33 is located behind the film tearing roller 32 along the feeding direction of the to-be-torn piece 100.

[0045] The film tearing auxiliary device is provided with a film tearing roller 32 on the side of the mounting plate 31 away from the to-be-torn piece 100 along the first direction, and a pressure roller 33 is provided on the side of the mounting plate 31 close to the to-be-torn piece 100 along the first direction, and the pressure roller 33 is located behind the film tearing roller 32 along the feeding direction of the to-be-torn piece 100, so that when tearing the film, the film tearing roller 32 is inserted into the side of the protective film 200 facing the to-be-torn piece 100, and the pressure roller 33 presses the protective film 200 on the to-be-torn piece 100, so that while tearing the film, the pressure roller 33 is used to press the area of ​​the protective film 200 to be torn. The film tearing mechanism 3 is rolled so that the protective film 200 and the piece to be torn 100 are more tightly attached before tearing the film, thereby avoiding the problem of poor glue pulling when tearing the film, and by connecting the mounting plate 31 with the lifting slider 21 sliding along the first direction on the lifting slide rail 22, the tearing angle of the protective film 200 can be adjusted when the film is torn by the film tearing roller 32, and the lifting slide rail 22 is connected to the turntable 11 driven to rotate by the rotating drive module 12, and the film tearing path is changed by adjusting the angle of the film tearing mechanism 3 to adapt to machines of different sizes and structures.

[0046] Continue to refer Figure 4 Optionally, a first chute 311 extending along a first direction is provided on the mounting plate 31, and the film tearing roller 32 is slidably disposed in the first chute 311. By providing the first chute 311 extending along the first direction on the mounting plate 31, the position of the film tearing roller 32 along the first direction can be adjusted, and the position of the film tearing roller 32 can be coordinated with the lifting mechanism 2 to achieve fine and coarse adjustment in the first direction, thereby improving the accuracy of the film tearing operation and the quality of the product after the film is torn.

[0047] Further, Figure 5 This is the structural decomposition diagram of the film tearing roller, such as Figure 5As shown, the film tearing roller 32 includes a first inner roller shaft 321, a first outer roller sleeve 322 and a first locking piece 323. The first inner roller shaft 321 can be slidably inserted into the first slide groove 311, and the first outer roller sleeve 322 can be rotatably sleeved on the first inner roller shaft 321. The first locking piece 323 is used to lock or unlock the first inner roller shaft 321 and the mounting plate 31.

[0048] By using a rotatable first outer roller sleeve 322 to be sleeved on the first inner roller shaft 321, the first outer roller sleeve 322 in contact with the protective film 200 can rotate freely when tearing the film. On the one hand, the friction between the protective film 200 and the first outer roller sleeve 322 is reduced. On the other hand, the rotation of the first outer roller sleeve 322 avoids adhesion between the protective film 200 and the first outer roller sleeve 322, thereby preventing the protective film 200 from falling off freely from the first outer roller sleeve 322 and preventing the protective film 200 from being entangled on the first outer roller sleeve 322.

[0049] In this embodiment, the film tearing roller 32 also includes a first bearing 324, the inner ring of the first bearing 324 is sleeved on the first inner roller shaft 321, and the first outer roller sleeve 322 is sleeved on the outer ring of the first bearing 324, thereby realizing the rotation of the first outer roller sleeve 322 relative to the first inner roller shaft 321.

[0050] Further, continue to refer to Figure 5 The first inner roller shaft 321 includes a first plug-in portion 3211 and a first support portion 3212 having a diameter larger than the first plug-in portion 3211. The first plug-in portion 3211 is provided with a first external thread and can be slidably inserted into the first slide groove 311. The first locking piece 323 is provided with a first threaded hole that cooperates with the first external thread. The first locking piece 323 is threadedly connected to the first plug-in portion 3211, and the first outer roller sleeve 322 is rotatably sleeved on the first support portion 3212. By providing a first external thread on the first plug-in portion 3211 of the first inner roller shaft 321 and a first threaded hole on the first locking member 323, when the position of the film-tearing roller 32 needs to be adjusted along the first direction, the first locking member 323 can be screwed to separate the first locking member 323 from the mounting plate 31, thereby enabling the first plug-in portion 3211 to slide in the first slide groove 311. Since the diameter of the first plug-in portion 3211 is smaller than the first support portion 3212, a shoulder is formed between the first plug-in portion 3211 and the first support portion 3212. After the adjustment is completed, the first locking member 323 is screwed in the opposite direction to abut against the mounting plate 31, so that the mounting plate 31 is clamped between the first locking member 323 and the shoulder, thereby completing the fixation of the first plug-in portion 3211 in the first slide groove 311. In this embodiment, the first locking member 323 is a hexagonal nut.

[0051] Optionally, Figure 6 This is the structural breakdown diagram of the pressure roller, such as Figure 6 As shown, the mounting plate 31 is provided with a second chute 312 extending in the second direction, and the pressure roller 33 is slidably disposed in the second chute 312. By providing the second chute 312 extending in the second direction on the mounting plate 31, the distance of the pressure roller 33 along the second direction can be adjusted. In cooperation with the film-tearing roller 32 inserted in the first chute 311, the spacing between the film-tearing roller 32 and the pressure roller 33 along the first and second directions can be freely adjusted, allowing for flexible adjustment and adaptability to a variety of products of different specifications and models.

[0052] Further, continue to refer to Figure 6 The pressure roller 33 includes a second inner roller shaft 331, a second outer roller sleeve 332 and a second locking piece 333. The second inner roller shaft 331 can be slidably inserted into the second slide groove 312, and the second outer roller sleeve 332 can be rotatably sleeved on the second inner roller shaft 331. The second locking piece 333 is used to lock or unlock the second inner roller shaft 331 and the mounting plate 31.

[0053] By using a rotatable second outer roller sleeve 332 to be sleeved on the second inner roller shaft 331, when the pressure roller 33 rolls the protective film 200 and the to-be-torn piece 100, the second outer roller sleeve 332 in contact with the protective film 200 can rotate freely, thereby causing rolling friction between the pressure roller 33 and the protective film 200, thereby reducing the friction between the protective film 200 and the second outer roller sleeve 332.

[0054] In this embodiment, the pressure roller 33 also includes a second bearing 334, the inner ring of the second bearing 334 is sleeved on the second inner roller shaft 331, and the second outer roller sleeve 332 is sleeved on the outer ring of the second bearing 334, thereby realizing the rotation of the second outer roller sleeve 332 relative to the second inner roller shaft 331.

[0055] Further, continue to refer to Figure 6The second inner roller shaft 331 includes a second plug-in portion 3311 and a second support portion 3312 with a diameter larger than the second plug-in portion 3311. The second plug-in portion 3311 is provided with a second external thread and can be slidably inserted into the second slide groove 312. The second locking piece 333 is provided with a second threaded hole that cooperates with the second external thread. The second locking piece 333 is threadedly connected to the second plug-in portion 3311, and the second outer roller sleeve 332 is rotatably sleeved on the second support portion 3312. By providing a second external thread on the second plug-in portion 3311 of the second inner roller shaft 331 and opening a second threaded hole on the second locking member 333, when the distance of the pressure roller 33 along the second direction needs to be adjusted, the second locking member 333 can be screwed to separate the second locking member 333 from the mounting plate 31, thereby allowing the second plug-in portion 3311 to slide within the second sliding groove 312. Since the diameter of the second plug-in portion 3311 is smaller than the second support portion 3312, a shoulder is formed between the second plug-in portion 3311 and the second support portion 3312. After the adjustment is completed, the second locking member 333 is screwed in the opposite direction to abut against the mounting plate 31, so that the mounting plate 31 is clamped between the second locking member 333 and the shoulder, thereby completing the fixation of the second plug-in portion 3311 within the second sliding groove 312. In this embodiment, the second locking member 333 is a hexagonal nut.

[0056] Optionally, Figure 2 It is a structural diagram of the rotating mechanism, such as Figure 2 As shown, the rotary drive module 12 includes a rotary drive member 121 and a rotary transmission unit 122. The rotary drive member 121 is arranged on one side of the turntable 11. The input end of the rotary transmission unit 122 is connected to the rotary drive member 121, and the output end of the rotary transmission unit 122 is connected to the turntable 11. The rotary transmission unit 122 is used to transmit the torque of the rotary drive member 121 to the turntable 11.

[0057] It should be noted that the reason why the rotary drive member 121 is arranged on one side of the rotary transmission unit 122, rather than the rotary drive member 121 directly replacing the input end of the rotary transmission unit 122, is to form a multi-stage transmission, thereby more accurately controlling the rotation speed and ensuring smooth rotation.

[0058] Exemplarily, the rotation transmission unit 122 is a gear set, with an input comprising a driving gear and a driving shaft, and an output comprising a driven gear and a driven shaft. The turntable 11 is mounted on the driven shaft along with the driven gear, and the driven gear meshes with the driving gear. The rotation drive member 121 is a motor, which drives the driving gear of the rotation transmission unit 122 to rotate, thereby driving the driven shaft on the driven gear, thereby rotating the turntable 11 mounted on the driven shaft. In this embodiment, the rotation transmission unit 122 is a speed reducer, which controls the rotation speed of the turntable 11 by adjusting the gear ratio, thereby ensuring smoother rotation of the turntable 11.

[0059] Optionally, Figure 3 It is a structural diagram of the lifting mechanism, such as Figure 3 As shown, the lifting drive module 23 includes a lifting screw 231, a lifting nut, and a lifting drive member 232. The lifting screw 231 is rotatably disposed within the lifting rail 22. The lifting nut is threadedly connected to the lifting screw 231 and connected to the lifting slider 21. The lifting drive member 232 is used to drive the lifting screw 231 to rotate. The threaded connection between the lifting screw 231 and the lifting nut converts the rotational motion of the lifting drive member 232 into linear motion of the lifting nut, thereby driving the lifting slider 21 connected to the lifting nut to slide along the lifting rail 22 in a first direction. By using lifting screws 231 with different pitches, the lifting distance can be controlled, thereby improving the accuracy of the lifting displacement of the lifting slider 21.

[0060] Exemplarily, the lifting drive component 232 is a motor, which is fixed to the top of the lifting slide rail 22, the lifting nut is fixedly connected to the lifting slider 21, and the lifting screw 231 is rotatably arranged inside the lifting slide rail 22. One end of the lifting screw 231 is connected to the motor, and the motor drives the lifting screw 231 to rotate, driving the lifting nut to rise and fall along the lifting screw 231.

[0061] In this embodiment, a film-tearing device is also provided, comprising the aforementioned film-tearing auxiliary device. Furthermore, the film-tearing device further comprises a conveying table 400 for conveying a workpiece 100 to be torn, to which a protective film 200 is adhered, and a cornering device 300 for lifting a corner of the protective film 200 on the workpiece 100 to be torn, so that a film-tearing roller 32 can be interposed between the protective film 200 and the workpiece 100 to be torn.

[0062] By applying the above-mentioned film-tearing auxiliary device, the film-tearing equipment can not only be flexibly adjusted according to different products, but also improve the problem of poor glue pulling during film tearing, thereby improving product quality.

[0063] Figure 7 This is a schematic diagram of the film tearing equipment using the film tearing auxiliary device to perform film tearing operations, such as Figure 7As shown, when the film tearing device uses the film tearing auxiliary device to tear the film, the piece 100 to be torn is first placed on the conveying workbench 400, and the conveying workbench 400 conveys the piece 100 to be torn along the feeding direction, and then the corner of the protective film 200 is glued up by the cornering device 300, so that a gap for insertion appears between the protective film 200 and the piece 100 to be torn. It can be understood that the cornering device 300 in this embodiment can be, for example, a robot with a clamping function, and then the film tearing auxiliary device is used. The rotating mechanism 1 and the lifting mechanism 2 are arranged to adjust the height and angle of the film tearing mechanism 3, and the film tearing roller 32 on the film tearing mechanism 3 will be inserted into the gap between the protective film 200 and the piece to be torn 100. At this time, the pressing roller 33 is pressed tightly on the side of the protective film 200 and the piece to be torn 100 away from the film tearing roller 32. As the piece to be torn 100 moves along the feeding direction, the protective film 200 is clamped by the angle-raising device 300 and the film tearing roller 32 assists in adjusting the film tearing angle, so that it is gradually torn off, completing the film tearing operation.

[0064] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
