Description

Technical Field

[0001] This application relates to the field of film-assisted application tools, and in particular to a faceplate anti-leakage film auxiliary application device. Background Technology

[0002] As the peripheral component of a television set, the bezel (or frame) significantly impacts the overall viewing experience of the television. Especially in terms of light transmission prevention, good light transmission control enhances display quality and provides a better visual experience for users. Therefore, after the bezel is manufactured, a protective film is typically applied to the back of the bezel to ensure effective light transmission prevention after installation.

[0003] Currently, to ensure the light-blocking effect after the faceplate is installed, the light-blocking film is usually applied manually. Specifically, workers hold strips of the light-blocking film and attach them one by one to the four sides of the faceplate. To ensure a firmer adhesion, workers typically use a pressure bar or roller to roll over the film and press it down. This method is effective for applying the light-blocking film and is a relatively traditional and widely used technique in the industry.

[0004] However, the aforementioned method of manually applying the opaque film has gradually revealed its shortcomings under the conditions of large-scale production and high-quality requirements. This method requires a high level of experience and skill from workers, and the difference in operational skill levels among different workers will lead to unstable film quality. Furthermore, during manual operation, it is easy to misalign the film or cause it to adhere poorly, making it difficult to effectively guarantee the overall bonding quality. This method cannot meet the increasingly stringent production quality standards and needs improvement. Utility Model Content

[0005] To address the issue that traditional manual application of light-blocking film cannot guarantee the quality of the film application, this application provides an auxiliary device for applying light-blocking film to a face frame.

[0006] This application provides a faceplate anti-light leakage film auxiliary attachment device, which adopts the following technical solution: A faceplate anti-leakage film auxiliary application device includes a frame, a limiting block for placing a faceplate is provided on the frame, and a limiting groove is formed on the limiting block to fit into the faceplate. Guide rails are provided around the limiting block on the frame, the axis of any guide rail is parallel to the side of the adjacent faceplate, and a mounting seat is slidably embedded in any guide rail. A connecting block is provided on the side of any mounting seat away from the guide rail, and a pressing mechanism is provided on the side of any connecting block near the limiting block for pressing the anti-leakage film tightly onto the faceplate.

[0007] By adopting the above technical solution, the frame provides a supporting foundation for the entire device. The limiting block with limiting groove on the frame can accurately fix the position of the face frame and prevent the face frame from shifting during the application process. The guide rails parallel to the side of the face frame are set around the limiting block. At the same time, the mounting base that can slide on the guide rail, as well as the connecting block and pressing mechanism set on the mounting base, can realize the tight application of the light leakage prevention film on the four sides of the face frame, avoid the problem of unstable film quality when manually applying the film, and ensure the quality of the film application.

[0008] Preferably, any of the clamping mechanisms includes a fixed frame, a lifting block, a guide rod, a lifting handle, a limiting wheel, and a clamping wheel. The fixed frame is disposed on the side of the connecting block near the limiting block. The guide rod is fixed vertically on the side of the fixed frame away from the connecting block. The lifting block is slidably disposed on the guide rod. A spring is disposed between the lifting block and the upper end of the fixed frame, and the spring is sleeved on the guide rod. Two lifting handles are disposed and fixed on both sides of the lifting block respectively. The limiting wheel and the clamping wheel are rotatably disposed on the side of the lifting block near the limiting block along the axial direction of the guide rail. The limiting wheel has a positioning groove that forms a limiting fit with the anti-leakage film. The rotation axes of the limiting wheel and the clamping wheel are both arranged perpendicular to the axial direction of the guide rail.

[0009] By adopting the above technical solution, the fixed frame in the pressing mechanism provides a supporting foundation for the entire pressing mechanism. The guide rod is fixed in the vertical direction and the lifting block slides along it, which can guide the movement of the lifting block. The spring is located between the lifting block and the upper end of the fixed frame and is sleeved on the guide rod. Under the guidance of the guide rod, it can provide vertical elastic support force to drive the lifting block to descend, thereby driving the limit wheel and the pressing wheel to descend. The positioning groove on the limit wheel can accurately constrain the position of the anti-leakage film and prevent the anti-leakage film from shifting during the application. The pressing wheel presses the anti-leakage film tightly against the face frame under the elastic action of the spring, ensuring that the anti-leakage film is tightly attached to the face frame and ensuring the quality of the film application. The lifting handle is set on both sides of the lifting block, which makes it convenient for workers to lift the lifting block. Then, the elastic action of the spring drives the limit wheel and the pressing wheel to press down, thereby achieving the pressing and application of the anti-leakage film.

[0010] Preferably, anti-slip posts are provided at both ends of any of the guide rails.

[0011] By adopting the above technical solution, anti-slip columns are set at both ends of the guide rail to prevent the mounting base from slipping off the guide rail, thus ensuring the stability and reliability of the device operation.

[0012] Preferably, any of the anti-slip posts can be detachably fixed to the guide rail.

[0013] By adopting the above technical solutions, the anti-slip column can be flexibly installed or disassembled according to actual needs, which facilitates the maintenance and replacement of parts of the device and enhances the flexibility and applicability of the device.

[0014] Preferably, the horizontal distance between any of the clamping mechanisms and the adjacent face frame side is adjustable.

[0015] By adopting the above technical solution, the horizontal distance between the pressing mechanism and the adjacent side of the face frame is adjustable, so that the position of the pressing mechanism can be flexibly adjusted according to the actual situation. This allows the pressing mechanism to accurately press and attach the anti-leakage film to the face frame, thereby improving the adhesion quality and stability of the anti-leakage film.

[0016] Preferably, any of the mounting bases includes a sliding block embedded and slidably disposed on a guide rail and a micrometer slide disposed on the sliding block. The sliding direction of the sliding plate of the micrometer slide on the fixed plate is perpendicular to the movement direction of the sliding block. The connecting block is disposed on the sliding plate of the micrometer slide. Adjusting plates are provided on both sides of the micrometer slide. The side of any adjusting plate closest to the fixed plate of the micrometer slide is fixedly connected to it. The side of any adjusting plate away from the fixed plate of the micrometer slide has a waist-shaped groove. An adjusting bolt is slidably disposed in the waist-shaped groove of any adjusting plate. The adjusting bolt passes through the corresponding waist-shaped groove and is threadedly connected to the sliding plate of the micrometer slide.

[0017] By adopting the above technical solution, the sliding block in the mounting base can slide along the guide rail, thereby driving the micrometer slide, connecting block and pressing mechanism to slide along the guide rail, realizing the pressing and attachment of the light leakage prevention film on the face frame. The micrometer slide in the mounting base can realize the fine adjustment of the working position of the pressing mechanism, meeting the strict requirements of high-quality film application for dimensional accuracy. The waist-shaped groove opened on the adjustment plate cooperates with the adjustment bolt to further enhance the stability and reliability of the adjustment process. At the same time, after adjustment, the position can be fixed by tightening the adjustment bolt to ensure the structural stability after adjustment.

[0018] Preferably, any of the clamping mechanisms is rotatably mounted on the connecting block, and the rotation axis of any of the clamping mechanisms is arranged parallel to the axis of the guide rail.

[0019] By adopting the above technical solution, the pressing mechanism is rotatably mounted on the connecting block. After the pressing mechanism presses the anti-leakage film onto the face frame along the guide rail, the worker can directly rotate and lift the entire pressing mechanism, thereby making it easier to reset the entire device along the guide rail for the next application operation, effectively improving the smoothness and continuity of the operation.

[0020] Preferably, any of the connecting blocks has a groove with an opening facing the limiting block, and a rotating block is rotatably disposed in the groove of any of the connecting blocks. Any of the pressing mechanisms is disposed on the side of the corresponding rotating block close to the limiting block, and a locking bolt is threadedly connected to any of the connecting blocks to form an abutment fit with the rotating block.

[0021] By adopting the above technical solution, when the pressing mechanism needs to be reset after the attachment is completed, the locking bolts can be loosened by turning them, and the rotating block can be used to drive the pressing mechanism to rotate and lift flexibly. This makes it convenient for the device to be reset along the guide rail for the next attachment operation, improving the convenience and smoothness of the overall operation and meeting the needs of continuous production. At the same time, after the device is reset, the locking bolts can be turned to abut against the rotating block to fix it, ensuring the structural stability of the pressing mechanism during the attachment process.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The limiting groove on the limiting block limits the face frame, preventing it from shifting during the application process. At the same time, the guide rails around the limiting block cooperate with the mounting base, which can drive the pressing mechanism to move smoothly along the guide rails, so as to press and attach the anti-leakage film on the four sides of the face frame, improve the stability and accuracy of the anti-leakage film application process, effectively ensure the film quality, and solve the problem of unstable film quality in traditional manual application methods. The two ends of the guide rail are equipped with detachable anti-slip posts to prevent the mounting base from slipping off the guide rail. The anti-slip posts can be flexibly installed or removed according to actual needs, which facilitates the maintenance and replacement of parts of the device. 2. The positioning groove on the limit wheel in the pressing mechanism can accurately constrain the position of the light leakage prevention film and prevent the light leakage prevention film from shifting during the application. The pressing wheel can press the light leakage prevention film firmly onto the face frame, avoiding the situation that it is easy to apply crookedly and the adhesion is not stable when manually operated. 3. The horizontal distance between the clamping mechanism and the side of the face frame can be adjusted, allowing the effective position of the clamping mechanism to be flexibly adjusted according to the actual situation. This enables the clamping mechanism to accurately press and attach the anti-leakage film onto the face frame. At the same time, the clamping mechanism is rotatably mounted on the connecting block. After the clamping mechanism presses and attaches the anti-leakage film onto the face frame along the guide rail, the worker can directly rotate and lift the entire clamping mechanism, making it easier to reset the entire device along the guide rail for the next application operation.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0026] This application discloses an auxiliary device for attaching a light-blocking film to a faceplate.

[0027] Reference Figure 1 and Figure 2 A faceplate light-leakage prevention film auxiliary application device includes a frame 1. A limiting block 2 for placing a faceplate is bolted to the frame 1, and the limiting block 2 has a limiting groove 21 that fits into the faceplate. Guide rails 3 are bolted to all four sides of the limiting block 2 on the frame 1. The axis of any guide rail 3 is parallel to the side of the adjacent faceplate, and anti-slip posts 4 are detachably fixed to both ends of each guide rail 3. In this embodiment, four guide rails 3 are provided. Each guide rail 3 has threaded grooves at both ends, and the anti-slip posts 4 at both ends of each guide rail 3 are threaded vertically to the guide rail. 3. A mounting base 5 is slidably embedded in any of the guide rails 3. A connecting block 6 is fixedly connected to the side of any of the mounting bases 5 away from the guide rails 3 by bolts. A pressing mechanism 7 for pressing the light-proof film onto the face frame is provided on the side of any of the connecting blocks 6 near the limiting block 2. In this embodiment, four of the mounting bases 5, connecting blocks 6 and pressing mechanisms 7 are provided for each of the four guide rails 3. The horizontal distance between any of the pressing mechanisms 7 and the adjacent side of the face frame is adjustable. Any of the pressing mechanisms 7 is rotatably mounted on the connecting block 6. The rotation axis of any of the pressing mechanisms 7 is parallel to the axis of the guide rails 3.

[0028] In practical use, the frame 1 provides a supporting foundation for the entire device. After the worker inserts the face frame without the anti-leakage film into the limiting groove 21 on the limiting block 2, the face frame is precisely fixed to prevent displacement during the application process. Then, four workers attach one end of each of the four anti-leakage films to one end of each of the four sides of the face frame. Using the four guide rails 3 around the limiting block 2, along with the mounting base 5, connecting block 6, and pressing mechanism 7 that can slide on the guide rails 3, the four anti-leakage films are pressed and attached to the four sides of the face frame, thus avoiding the problem of unstable film quality during manual application and ensuring the quality of film application. The anti-slip posts 4 at both ends of the guide rails 3 can prevent the mounting base 5 from driving the connecting block 6 and the pressing mechanism 7 to slip off the guide rails 3, ensuring the stability and reliability of the device operation. At the same time, the anti-slip posts 4 are detachable, allowing them to be flexibly installed or removed according to actual needs, enhancing the flexibility and applicability of the device. When applying the film, the worker can flexibly adjust the horizontal distance between the pressing mechanism 7 and the adjacent side of the face frame according to whether the pressing mechanism 7 is in an accurate position. This allows the pressing mechanism 7 to accurately press and apply the anti-leakage film onto the face frame, thereby improving the application quality and stability of the anti-leakage film. After the pressing mechanism 7 completes one pressing and application, the worker can directly rotate and lift the entire pressing mechanism 7 to reset the device along the guide rail 3 for the next application operation. This avoids interference between the pressing mechanism 7 and other components during the reset process, effectively improving the smoothness and continuity of the operation.

[0029] In the faceplate light-leakage film auxiliary application device disclosed in the embodiments of this application, the mounting base 5, connecting block 6 and pressing mechanism 7 on the four guide rails 3 around the limiting block 2 have the same structure, connection relationship and function. The mounting base 5, connecting block 6 and pressing mechanism 7 on one of the guide rails 3 will be described in detail below: Reference Figure 2 and Figure 3The mounting base 5 includes a sliding block 51 embedded and slidably mounted on the guide rail 3, and a micrometer slide 52 mounted on the sliding block 51. The sliding direction of the sliding plate 521 of the micrometer slide 52 on the fixed plate 522 is perpendicular to the movement direction of the sliding block 51. The fixed plate 522 of the micrometer slide 52 is bolted to the side of the sliding block 51 away from the guide rail 3, and the connecting block 6 is bolted to the side of the sliding plate 521 of the micrometer slide 52 away from the guide rail 3. Adjusting plates 8 are provided on both sides of the micrometer slide 52. The side of any adjusting plate 8 closest to the fixed plate 522 of the micrometer slide 52 is open to the guide rail 3. The adjusting plate 8 is fixedly connected to the fixing plate 522 of the micrometer slide table 52 by bolts, and a waist-shaped groove 81 is opened on the side of the adjusting plate 8 away from the fixing plate 522 of the micrometer slide table 52. An adjusting bolt 811 is slidably arranged in the waist-shaped groove 81 of the adjusting plate 8, and the adjusting bolt 811 passes through the corresponding waist-shaped groove 81 and is threadedly connected to the sliding plate 521 of the micrometer slide table 52. In the embodiment of this application, the side of the adjusting plate 8 close to the fixing plate 522 of the micrometer slide table 52 is fixedly connected to it by two bolts, and two adjusting bolts 811 threadedly connected to the sliding plate 521 of the micrometer slide table 52 are also slidably arranged in the waist-shaped groove 81 of the adjusting plate 8.

[0030] In practical use, when workers observe that the working position of the clamping mechanism 7 is inaccurate, they first loosen the adjusting bolt 811 to allow for position adjustment. Then, by turning the adjusting knob 523 on the micrometer slide 52, the sliding plate 521 of the micrometer slide 52 moves slowly on the fixed plate 522 to precisely adjust the horizontal distance between the clamping mechanism 7 and the adjacent face frame side, thereby meeting the strict dimensional accuracy requirements of high-quality film application. During the adjustment process, the adjusting bolt 811 can follow the micrometer slide. The sliding plate 521 of 52 slides synchronously in the waist-shaped groove 81, further enhancing the stability and reliability of the adjustment process. After the adjustment is completed, the position can be fixed by tightening the adjusting bolt 811 to press against the adjusting plate 8, ensuring the structural stability after adjustment. After the working position of the clamping mechanism 7 is accurately adjusted, the sliding block 51 in the mounting base 5 slides along the guide rail 3, driving the micrometer slide table 52, the connecting block 6 and the clamping mechanism 7 to slide synchronously, so that the clamping mechanism 7 can accurately press the anti-leakage film onto the face frame.

[0031] Reference Figure 2 and Figure 3The connecting block 6 has a groove 61 with an opening facing the limiting block 2, and a rotating block 9 is rotatably disposed in the groove 61 on the connecting block 6. The clamping mechanism 7 is fixedly connected to the side of the rotating block 9 near the limiting block 2, and a locking bolt 62 is threadedly connected to the connecting block 6 to form an abutment fit with the rotating block 9. In this embodiment, the rotating block 9 is L-shaped, and one end of the rotating block 9 embedded in the groove 61 is arc-shaped. A rotating shaft 611 parallel to the axis of the guide rail 3 is disposed in the groove 61 on the connecting block 6. The rotating shaft 611 passes through the rotating block 9, and both ends of the rotating shaft 611 are fixedly connected to the inner wall of the groove 61 by welding. When the side of the rotating block 9 near the mounting base 5 rotates to abut the mounting base 5, the side of the rotating block 9 near the limiting block 2 is vertically disposed.

[0032] In practical use, after the pressing mechanism 7 completes one application, the worker loosens it by tightening the locking bolt 62, allowing the rotating block 9 to rotate around the rotating shaft 611 within the groove 61 on the connecting block 6. This causes the rotating block 9 to drive the pressing mechanism 7 to rotate and lift, so that the device can be reset along the guide rail 3 for the next application operation. This avoids interference between the pressing mechanism 7 and other components during the reset process, improving the convenience and smoothness of the overall operation and meeting the needs of continuous production. The end of the rotating block 9 embedded in the groove 61 is arc-shaped, which can prevent interference between the rotating block 9 and the connecting block 6 when rotating, further ensuring the smoothness of the rotation and lifting of the pressing mechanism 7. After the device is reset, the worker can fix it by tightening the locking bolt 62 to press it against the rotating block 9, preventing the rotating block 9 from rotating during the next application process and ensuring the structural stability of the pressing mechanism 7 during the application process.

[0033] Reference Figure 2 and Figure 4The clamping mechanism 7 includes a fixed frame 71, a lifting block 72, a guide rod 73, a lifting handle 74, a limiting wheel 75, and a clamping wheel 76. The fixed frame 71 is located on the side of the connecting block 6 near the limiting block 2. In this embodiment, the fixed frame 71 includes a connecting plate 711 and a positioning plate 712. The connecting plate 711 is fixedly connected to the side of the rotating block 9 near the limiting block 2 by welding. Two positioning plates 712 are provided, both located on the side of the connecting plate 711 near the limiting block 2, and the two positioning plates 712 are respectively fixedly connected to the two ends of the connecting plate 711 in the vertical direction by welding. The guide rod 73 is fixed to the fixed frame in the vertical direction. 71 is located away from the side of the connecting block 6, and the lifting block 72 is slidably mounted on the guide rod 73. A spring 731 is provided between the lifting block 72 and the upper end of the fixed frame 71, and the spring 731 is sleeved on the guide rod 73. In this embodiment, there are two guide rods 73. Each guide rod 73 passes through the lifting block 72, and the two ends of each guide rod 73 are fixedly connected to the side of the two positioning plates 712 that are close to each other by welding. There are also two springs 731 corresponding to the number of guide rods 73. Both springs 731 are located between the lifting block 72 and the positioning plate 712 away from the guide rail 3, and the two springs 731 are respectively sleeved on the two guide rods 73. Reference Figure 2 and Figure 4 The lifting handle 74 is provided in two parts and is fixedly connected to both sides of the lifting block 72 by bolts. The limiting wheel 75 and the pressing wheel 76 are rotatably arranged on the side of the lifting block 72 near the limiting block 2 along the axis of the guide rail 3. The limiting wheel 75 has a positioning groove 751 that forms a limiting fit with the anti-leakage film. The rotation axes of the limiting wheel 75 and the pressing wheel 76 are both arranged perpendicular to the axis of the guide rail 3. In this embodiment, the pressing block 77 is fixedly connected to the side of the lifting block 72 near the limiting block 2 by welding. The pressing block 77 is rotatably connected to the first rotating shaft 771 and the second rotating shaft 772 along the axis of the guide rail 3 on the side near the limiting block 2. The axis of the first rotating shaft 771 and the second rotating shaft 772 are both arranged perpendicular to the axis of the guide rail 3. The limiting wheel 75 is coaxially fixedly connected to the first rotating shaft 771 and the pressing wheel 76 is coaxially fixedly connected to the second rotating shaft 772.

[0034] In practical use, the connecting plate 711 and the positioning plate 712 in the fixing frame 71 combine to provide an installation base for the entire pressing mechanism 7. After the worker attaches one end of the light-proof film to one end of one side of the face frame, the worker uses the lifting handle 74 to lift the lifting block 72, thereby lifting the pressing block 77 and the limiting wheel 75 and pressing wheel 76 on the pressing block 77. During the lifting process, the guide rod 73 provides guidance for the movement of the lifting block 72 to ensure the stability of the lifting. Then, the worker pushes the mounting base 5 to move the entire pressing mechanism 7. When the limiting wheel 75 and pressing wheel 76 move to directly above the end of the light-proof film, the worker releases the lifting handle. Handle 74 causes lifting block 72 to descend under the elastic action of spring 731, thereby causing lifting block 72 to drive pressing block 77 and the limiting wheel 75 and pressing wheel 76 on pressing block 77 to descend, so that the positioning groove 751 on the limiting wheel 75 can accurately constrain the anti-leakage film and prevent the anti-leakage film from shifting during the application. At the same time, the pressing wheel 76 is used to press and attach the anti-leakage film to ensure that the anti-leakage film is tightly attached to the face frame. Finally, the worker continuously pushes the mounting base 5 to slide along the guide rail 3, causing the limiting wheel 75 to rotate continuously around the first rotating shaft 771 and the pressing wheel 76 to rotate continuously around the second rotating shaft 772, thus completing the pressing and attachment of the entire anti-leakage film.

[0035] The implementation principle of this application embodiment is as follows: the frame 1 is used as the overall support base, and the face frame is accurately embedded and fixed by the limiting groove 21 on the limiting block 2, so as to avoid the face frame from shifting during the application process and to provide a stable reference for subsequent film application operations; the four guide rails 3 on the frame 1 located around the limiting block 2 are respectively arranged parallel to the four sides of the face frame, and the mounting seat 5 on any guide rail 3 can slide along the guide rail 3, thereby driving the connecting block 6 and the pressing mechanism 7 to move synchronously, so as to achieve accurate application of the anti-light leakage film on the four sides of the face frame respectively; Mounting base 5 forms a sliding engagement with guide rail 3 through sliding block 51. The sliding plate 521 of micrometer slide table 52 in mounting base 5 can move on fixed plate 522 in a direction perpendicular to guide rail 3. With the waist-shaped groove 81 and adjusting bolt 811 on the adjusting plates 8 on both sides of micrometer slide table 52, the horizontal distance between pressing mechanism 7 and side of face frame can be precisely adjusted by adjusting knob 523 of micrometer slide table 52 to meet the high-precision film application requirements. After adjustment, the position can be fixed by tightening adjusting bolt 811 to ensure structural stability. Connecting block 6 is connected to pressing mechanism 7 through rotating block 9 in groove 61. At the same time, rotating block 9 can rotate around rotating axis 611 parallel to guide rail 3 and is fixed and loosened with locking bolt 62. When applying, tightening locking bolt 62 to press it against rotating block 9 can ensure the stability of the mechanism. After applying, tightening locking bolt 62 to loosen it can rotate and lift pressing mechanism 7, avoiding interference with other parts when pressing mechanism 7 is reset, and improving the continuity of operation. The fixed frame 71 in the pressing mechanism 7 provides the mounting base for each component. The guide rod 73 guides the lifting block 72 to move vertically, and the spring 731 provides elastic pressure when the lifting block 72 descends. After the worker lifts the lifting block 72 by lifting the handle 74, he aligns the limiting wheel 75 and the pressing wheel 76 with the anti-leakage film. After releasing the handle, the limiting wheel 75 forms a limiting constraint on the anti-leakage film through the positioning groove 751 to prevent displacement. The pressing wheel 76 presses the anti-leakage film onto the face frame under the elastic force of the spring 731. Then, the worker continues to push the mounting base 5 to slide along the guide rail 3, so that the limiting wheel 75 and the pressing wheel 76 roll synchronously, thus completing the continuous and tight application of the entire anti-leakage film. Through the coordinated cooperation of each structure, the entire device achieves precise positioning, stable pressing and efficient operation in the application process of the anti-leakage film on the face frame, effectively improving the film application quality and production efficiency.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
