Description

Technical Field

[0001] This application relates to the technical field of film-tearing equipment, and in particular to a film-tearing device. Background Technology

[0002] As a key piece of equipment in precision manufacturing, film peeling machines have wide and indispensable applications in industries such as electronics, optics, automotive, and semiconductors. In the electronics industry, products such as mobile phones and computers are constantly evolving towards thinner, lighter, and higher-performance designs. The precision required for peeling films from internal microchips and flexible circuit boards is extremely high; even slight deviations can lead to product malfunctions. In the optics field, the peeling of protective films on lenses and optical elements must ensure extremely high surface quality to prevent scratches from affecting image quality. In the automotive industry, the removal of films from components such as dashboards and in-vehicle displays directly impacts the product's appearance and user experience. The semiconductor industry has even more stringent standards for film peeling precision and cleanliness.

[0003] Traditional manual film removal can process at most a few dozen sheets per hour, and due to different operating techniques, the film residue rate is relatively high.

[0028] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0029] Please see Figures 1 to 6 This application provides a film-peeling device that can be used to peel off the protective film on the surface of a product to ensure product quality and smooth subsequent processing. The film-peeling device includes a film-lifting mechanism 1, a film-lifting pressure plate mechanism 2, a film-gripping mechanism 3, and a conveying mechanism 4. The product 48 is horizontally placed on the conveying mechanism 4 for conveying. The conveying mechanism 4 includes an infeed station 39, a film-lifting station 40, and an outfeed station 41 connected in sequence.

[0030] Specifically, the film lifting and pressing mechanism 2 is located between the film lifting station 40 and the delivery station 41. The film lifting and pressing mechanism 2 is equipped with clamping components 23 for clamping the edges of the product 48. The film lifting mechanism 1 has two sets, located on both sides of the film lifting and pressing mechanism 2. The film lifting mechanism 1 includes two sets of film lifting components 10 symmetrically arranged in the vertical direction. Each set of film lifting components 10 is used to adhere and lift the film at two corners of the upper and lower sides of the product 48. The film gripping mechanism 3 includes two sets of film gripping components 30 respectively located above and below the film lifting station 40. The film gripping components 30 clamp the film lifted by the film lifting components 10 and drive the film to move in the opposite direction of the product 48's transport.

[0031] Product 48 is placed horizontally on conveying mechanism 4. Conveying mechanism 4 transports product 48 from feeding station 39 to film-lifting station 40, at which point product 48 is in a state awaiting film removal. After product 48 arrives at film-lifting station 40, clamping component 23 of film-lifting pressure plate mechanism 2 clamps the edge of product 48, fixing product 48 and preventing it from moving or shaking during the film-lifting process, ensuring the stability and accuracy of the film-lifting operation. Two sets of film-lifting components 10 of film-lifting mechanism 1 are symmetrically arranged on both sides of product 48. Each set of film-lifting components 10 adheres to and lifts the film at the two corners of the upper and lower sides of product 48, separating the corners of the film from the surface of product 48 for subsequent film gripping and tearing. In the film gripping mechanism 3, two sets of film gripping components 30, located above and below the film lifting station 40, respectively clamp the film lifted by the film lifting component 10. The film is then moved in the opposite direction to the product 48. At this point, the clamping component 23 releases the product 48, and the conveying mechanism 4 continues to convey the product 48 from the film lifting station 40 to the delivery station 41. Therefore, as the film gripping components 30 and the product 48 move in opposite directions, the film is gradually peeled off the surface of the product 48. With the film gripping mechanism 3 moving the film and the continuous operation of the conveying mechanism 4, the product 48 is conveyed to the delivery station 41, completing the entire film peeling process.

[0032] To address this, the film-tearing device, through the coordinated operation of multiple mechanisms, automates the entire process from film lifting and gripping to film peeling. Compared to manual film tearing, it significantly improves tearing efficiency and meets the needs of large-scale production. The film lifting mechanism 1 features two symmetrically arranged film lifting components 10 that lift the film from the corners of the product 48. The film gripping mechanism 3, which moves the film in the opposite direction of the product 48's transport, ensures the film is peeled off evenly and completely from the product 48's surface. This avoids film residue or scratches and damage to the product 48's surface during the tearing process, ensuring the quality of the product 48. Furthermore, this film-tearing device is applicable to products 48 of different sizes and shapes. As long as the product 48 can be placed on the conveying mechanism 4 and pass through various stations, the protective film can be peeled off. It has strong versatility and adaptability, meeting the tearing needs of various products 48.

[0033] Please see Figure 2In one specific embodiment, the film-lifting and pressing mechanism 2 further includes a first driving assembly 26. The first driving assembly 26 includes a first motor 27 and a first moving member 28. The first motor 27 is fixed to the conveying mechanism 4 at the delivery station 41, and the first moving member 28 is fixed to the horizontal driving end of the first motor 27. The first motor 27 can drive the first moving member 28 to move towards the delivery station 39, and the first moving member 28 has a through-plate gap 29 through which the product 48 can pass. The clamping assembly 23 includes two sets of clamping motors 24 and film-lifting clamping members 25 symmetrically arranged in the vertical direction. The two clamping motors 24 are respectively fixed to the upper and lower sides of the through-plate gap 29, and the vertical driving ends of the clamping motors 24 are respectively connected to the film-lifting clamping members 25 to drive the two film-lifting clamping members 25 to move towards each other to clamp the edge of the product 48, or to move in opposite directions to release the product 48.

[0034] Product 48 is conveyed by conveying mechanism 4 to one end of film-lifting station 40 near delivery station 41. First motor 27 drives first moving component 28 to move toward product 48. Two clamping motors 24 on the upper and lower sides of the through-plate gap 29 drive connected film-lifting clamping components 25 to move toward each other, thereby clamping the unfilmed area of ​​the edge of product 48 to position product 48, facilitating film lifting by film-lifting mechanism 1 and improving the accuracy and efficiency of film lifting. After the two sets of film-lifting assemblies 10 lift the film from the corner of product 48, the two clamping motors 24 drive the two film-lifting clamping components 25 to move in opposite directions, releasing product 48. At the same time, conveying mechanism 4 continues to convey product 48, and product 48 enters delivery station 41 through through-plate gap 29 of first moving component 28.

[0035] Please see Figure 3 In one specific embodiment, the film-lifting mechanism 1 further includes a groove frame 16, a second drive assembly 17, and a third drive assembly 20. The groove frames 16 are symmetrically arranged on both sides of the film-lifting pressure plate mechanism 2. The second drive assemblies 17 are symmetrically arranged on the two groove frames 16. Each set of second drive assemblies 17 includes a second motor 18 and a second moving member 19. The second motor 18 is fixed on the groove frame 16, and the second moving member 19 is fixed to the horizontal drive end of the second motor 18. The second motor 18 drives the second moving member 19 to move closer to the film-lifting station 40. Two sets of third drive assemblies 20 are symmetrically arranged vertically on each set of second moving members 19. Each third drive assembly 20 includes a third motor 21 and a third moving member 22. The third moving member 22 is fixed to the vertical drive end of the third motor 21, and the film-lifting assembly 10 is arranged on the third moving member 22. The two third motors 21 drive the two third moving members 22 to move closer to each other, so that the film-lifting assembly 10 lifts the film at the upper and lower corners of the product 48.

[0036] The second motor 18 drives the second moving part 19 to move closer to the film-lifting station 40, causing the second moving part 19 to bring the third driving component 20 and the film-lifting component 10 closer to the product 48. When the second moving part 19 reaches the set position, the two third motors 21 drive the two third moving parts 22 to move closer to each other, causing the film-lifting component 10 mounted on the third moving part 22 to adhere to and lift the film at the upper and lower corners of the product 48. After film lifting is completed, the second moving part 19 and the third moving part 22 automatically reset. Through the cooperation of the second driving component 17 and the third driving component 20, the film-lifting component 10 can move horizontally and vertically, precisely adjusting its position to accurately reach the corners of the product 48 for film lifting, thus improving the accuracy of film lifting. The symmetrical structural design allows for simultaneous film lifting operations at the two corners of the upper and lower sides of the product 48, improving work efficiency and reducing film-tearing time.

[0037] In one specific embodiment, the film lifting assembly 10 includes an unwind reel 11, a take-up reel 12, a film roll 13, a film lifting wheel 14, and a plurality of tensioning wheels 15. The unwind reel 11 and take-up reel 12 are respectively adjacent to and rotatably mounted on a third moving member 22, and are each connected to a rotating motor. The film lifting wheel 14 is rotatably mounted on the end of the third moving member 22 near the product 48. The tensioning wheels 15 are spaced apart between the unwind reel 11, take-up reel 12, and film lifting wheel 14. The film roll 13 is fixed on the unwind reel 11, and its movable end is sequentially rotatably connected to the film lifting wheel 14 and the tensioning wheels 15, while the movable end of the film roll 13 is fixed to the take-up reel 12.

[0038] When the third motor 21 drives the third moving component 22 to bring the film lifting assembly 10 close to the corner of the product 48, the movable end of the film roll 13 maintains a certain tension through the tensioning action of the tensioning wheel 15. When the film lifting wheel 14 contacts the film at the corner of the product 48, the film roll 13 on the film lifting wheel 14 adheres to the film. At this time, the take-up reel 12 rotates, winding the movable end of the film roll 13 back, thereby pulling the film roll 13 and driving the tensioning wheel 15 and the film lifting wheel 14 to rotate, so that the film roll 13 and the adhered film are lifted. As the take-up reel 12 continues to rotate, the film is continuously lifted until the film near the end of the film lifting pressure plate mechanism 2 is completely lifted, making it convenient for the subsequent film lifting by the die gripping mechanism 3.

[0039] To address this, the coordinated operation of the unwind reel 11, rewind reel 12, film roll 13, film lifting roller 14, and tension roller 15 enables continuous supply and rewinding of the film roll 13, ensuring the continuity of the film lifting process and improving lifting efficiency. The tension roller 15 maintains appropriate tension on the film roll 13, preventing it from becoming too loose or too tight, ensuring stable adhesion and film lifting, thus improving the reliability and stability of the film lifting process.

[0040] Please see Figure 4 In one specific embodiment, the film-gripping mechanism 3 further includes a first linear module 34, a movable frame 35, a second linear module 36, a fourth drive assembly 37, and a fifth drive assembly 38. The first linear module 34 is fixed to one side of the conveying mechanism 4 at the film-lifting station 40, and the movable frame 35 is connected to the horizontal drive end of the first linear module 34 along the conveying path of the product 48. Two sets of second linear modules 36 are symmetrically arranged vertically on the movable frame 35. The horizontal drive end of each set of second linear modules 36 is connected to the fourth drive assembly 37, the vertical drive end of the fourth drive assembly 37 is connected to the fifth drive assembly 38, and the vertical drive end of the fifth drive assembly 38 is connected to the film-gripping assembly 30. In this embodiment, both the fourth drive assembly 37 and the fifth drive assembly 38 are motors.

[0041] When a film lifting operation is required, the first linear module 34 drives the moving frame 35 to move along the product 48 conveying path to a set position. Then, the second linear module 36 is activated, driving the fourth drive assembly 37 to the set position. Subsequently, the fourth drive assembly 37 can drive the fifth drive assembly 38 to move vertically, and the fifth drive assembly 38 can drive the film gripping assembly 30 to move vertically, thereby adjusting the height of the two sets of film gripping assemblies 30 so that the two sets of film gripping assemblies 30 gradually approach the product 48, ultimately clamping the film lifted by the film lifting assembly 10 and driving the film to move in the opposite direction of the product 48 conveying, completing the film lifting action.

[0042] To address this, the cooperation of the first linear module 34, the second linear module 36, the fourth drive component 37, and the fifth drive component 38 enables multi-dimensional movement of the film gripping component 30 in both horizontal and vertical directions. This allows for precise adjustment of the film gripping component 30's position, ensuring accurate film gripping and improving gripping precision. The symmetrical structural design allows for simultaneous gripping of the film on both the upper and lower sides of the product 48, improving work efficiency and reducing gripping time.

[0043] In one specific embodiment, the film gripping assembly 30 includes a mounting frame 31, a cylinder 32, and a gripper 33. The mounting frame 31 is fixed to the vertical drive end of the fifth drive assembly 38. Cylinders 32 are respectively provided on both sides of the mounting frame 31 in the horizontal direction. The drive end of each cylinder 32 is connected to a gripper 33, and the gripper 33 is rotatably connected to the mounting frame 31.

[0044] When the fifth drive assembly 38 drives the mounting frame 31 to a set position close to the film, the film gripping assembly 30 is in the ready-to-grip state. At this time, the two cylinders 32 start working, and the drive ends of the cylinders 32 extend, pushing the two connected grippers 33 to rotate toward the product 48 until the grippers 33 clamp the film. When it is necessary to move the film, the first linear module 34 drives the mounting frame 31 and the film held by the grippers 33 to move in the opposite direction of the product 48's transport. The fourth drive assembly 37 and the fifth drive assembly 38 can drive the film to move away from the product 48 to provide sufficient space for film lifting, thus completing the film gripping and moving operations.

[0045] To address this, the combination of the mounting frame 31, cylinder 32, and gripper 33 enables effective film gripping, facilitating manufacturing, installation, and maintenance. The gripper 33 is rotatably connected to the mounting frame 31, allowing it to adjust according to the film's position and angle during gripping, thus improving the success rate of film gripping. The symmetrically arranged cylinders 32 and gripper 33 can simultaneously grip the film from both sides, ensuring uniform clamping force and preventing film displacement or damage during gripping, thus protecting both the film and product 48.

[0046] Please see Figure 5 In one specific embodiment, the film-tearing device further includes two sets of film-rubbing mechanisms 5 symmetrically arranged along the conveying mechanism 4. The film-rubbing mechanisms 5 are located between the feeding station 39 and the film-lifting station 40. Each set of film-rubbing mechanisms 5 includes a fixed plate 42, a sixth drive assembly 43, a seventh drive assembly 44, and a film-rubbing wheel 45. The fixed plate 42 is fixedly connected to one side of the conveying mechanism 4. The horizontal drive end of the sixth drive assembly 43 is symmetrically provided with two sets of seventh drive assemblies 44 in the vertical direction. The film-rubbing wheels 45 are rotatably connected to the vertical drive end of each set of seventh drive assemblies 44. The film-rubbing wheels 45 are used to roll on the film at the two corners of the upper and lower sides of the product 48 to rub open the film at the corners, facilitating the subsequent film-lifting operation.

[0047] Furthermore, the film-tearing device also includes a film-rubbing pressure plate mechanism 6, which is disposed between the two sets of film-rubbing mechanisms 5. The film-rubbing pressure plate mechanism 6 includes two sets of eighth drive assemblies 46 arranged vertically and film-rubbing clamping members 47. The eighth drive assemblies 46 are fixed to the conveying mechanism 4, and the film-rubbing clamping members 47 are fixedly connected to the vertical drive end of the eighth drive assemblies 46 to clamp the edge of the product 48.

[0048] When product 48 is conveyed by conveyor 4 to one end of the feeding station 39 near the film lifting station 40, the two sets of eighth drive components 46 drive the two film-rolling clamping members 47 to move towards each other to clamp the edge of product 48, keeping product 48 stable during the film rolling process. Subsequently, the sixth drive component 43 drives the two sets of seventh drive components 44, which are symmetrically arranged in the vertical direction, to move horizontally toward product 48. The two sets of seventh drive components 44 drive the film-rolling rollers 45 to move vertically, so that the film-rolling rollers 45 approach and contact the film at the two corners of the upper and lower sides of product 48. Then, the film-rolling rollers 45 begin to roll back and forth on the film, using rolling friction to roll open the film at the corners of product 48, preparing for subsequent film lifting. After the film rolling operation is completed, the eighth drive component 46 drives the film-rolling clamping members 47 to move in opposite directions, releasing product 48, which is then conveyed to the film lifting station 40.

[0049] To address this, the film-rolling pressure plate mechanism 6 firmly clamps the edges of the product 48 during the film-rolling process, preventing the product 48 from moving or shaking, ensuring smooth film-rolling operation, and improving film-rolling quality and effect. By pre-rolling the film edges and corners through the film-rolling mechanism 5, the adhesion between the film and the product 48 is reduced, making subsequent film-lifting operations easier and smoother, effectively improving film-lifting efficiency. Simultaneously, the rolling film-rolling method of the film-rolling roller 45 causes minimal damage to the film and product 48, better protecting the integrity of both and ensuring the quality of the product 48.

[0050] Please see Figure 6 In one specific embodiment, the film-tearing device further includes several film-blowing mechanisms 7, which are equidistantly arranged on one side of the conveying mechanism 4 of the film-lifting station 40. When the film-gripping mechanism 3 successfully lifts the film on the product 48 and moves it to a certain position, the film-blowing mechanism 7 receives a work command and starts to operate. The power unit (such as a fan) inside the film-blowing mechanism 7 generates airflow, which is blown out from the air outlet. Simultaneously, the equidistantly arranged film-blowing mechanisms 7 blow air onto the lifted film. The airflow acts on the film, causing it to experience an outward force. Under the continuous action of the airflow, the force on the film is sufficient to overcome the slight adhesive force between it and the film-gripping mechanism 3 or other components, as well as its own weight, thereby causing the film to detach from the film-gripping mechanism 3 and be blown off, completing the film-blowing operation.

[0051] In response, the blown film mechanism 7 can quickly and effectively blow the film off after the film gripping mechanism 3 lifts it, accelerating the separation process between the film and the product 48 and the film gripping mechanism 3, improving the overall efficiency of the film-tearing device, saving film-tearing time, and thus improving production efficiency. On the other hand, it further automates the film blowing operation, reducing manual intervention in film separation, lowering labor costs and labor intensity, and also reducing problems such as product 48 damage or film residue that may occur due to improper manual operation.

[0052] In one specific embodiment, residual film sensors 8 are respectively installed on the upper and lower sides of the film lifting station 40 near the delivery station 41. The residual film sensors 8 can accurately sense the film on the upper and lower sides to detect whether the lifted film is defective, thereby determining whether residual film remains on the surface of the product 48. Regardless of the size or location of the defect, as long as it is within the sensing range of the residual film sensor 8, it can be detected in a timely manner, preventing the product 48 with residual film from entering the next process and preventing the residual film from affecting the subsequent processing and use of the product 48, such as preventing appearance defects or performance impacts, thus ensuring the overall quality of the product 48. When the residual film sensor 8 detects a defect in the film, it can immediately trigger a corresponding processing mechanism, such as a machine stop alarm or activation of a cleaning device, to quickly handle the residual film problem, reduce delays and waste in the production process, and improve production efficiency.

[0053] Furthermore, plasma electrostatic bars 9 are respectively installed on the upper and lower sides of the film peeling station 40 near the delivery station 41. The plasma electrostatic bars 9 are arranged adjacent to the residual film sensor 8. The plasma electrostatic bars 9 can eliminate static electricity on the film, preventing residual film from remaining on the surface of the product 48 due to electrostatic adsorption. Together with the residual film sensor 8, they can better detect the presence of residual film, thereby ensuring the cleanliness of the product 48 surface after film peeling, further ensuring the quality of the product 48 and the smooth progress of subsequent processing.

[0054] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
