Description

Technical Field

[0001] This utility model relates to the field of bonding component technology, and in particular to a naked-eye 3D film bonding component with extended viewing angle. Background Technology

[0002] A naked-eye 3D film bonding assembly is a specialized device used to achieve precise bonding between the naked-eye 3D film and the display device. It is defined as an integrated device that accurately fixes the naked-eye 3D film onto the surface of the display screen through mechanical positioning, pressure application, and auxiliary structures. This assembly typically consists of a positioning system, a bonding actuator, a pressure adjustment module, and auxiliary components. The positioning system includes high-precision fixtures or positioning pins to ensure precise alignment between the naked-eye 3D film and the display screen, preventing bonding misalignment from affecting the 3D display effect.

[0003] The current limitations of the retaining frame in naked-eye 3D film bonding components have become a major obstacle to production flexibility and efficiency. Existing bonding components mostly employ integrated or fixedly connected retaining frame structures to secure the display device or naked-eye 3D film during the bonding process. These retaining frames are typically connected to the bonding equipment body via screws or welding, making them difficult to disassemble or replace once installed. When dealing with display screens or naked-eye 3D films of different sizes and shapes, the entire bonding component must be replaced or the retaining frame must be complexly modified, which is not only time-consuming and labor-intensive but may also lead to a decrease in equipment accuracy due to frequent disassembly and reassembly. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a naked-eye 3D film bonding component with an expanded field of view, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a naked-eye 3D film bonding assembly with expanded viewing angle, including a base frame and an electronic device body. The inner wall of the base frame is rotatably connected to a bidirectional lead screw via bearings. Two symmetrically arranged drive plates are threaded onto the outer surface of the bidirectional lead screw. Two symmetrically arranged connecting plates are fixedly connected to the top surface of each drive plate. A clamping plate is fixedly connected between the two connecting plates. The electronic device body is located between the two clamping plates. A support plate is fixedly connected to the top surface of the base frame. A sliding frame is slidably connected to the outer surface of the support plate. A locking bolt is threaded onto the front of the sliding frame, and the screw portion of the locking bolt is in contact with the support plate. Locking plates are slidably connected to both sides of the sliding frame. A film-applying limiting frame is fixedly connected between the two locking plates. The limiting frame is slidably connected to the support plate, and the film-applying limiting frame corresponds vertically to the electronic device body. A spring is fixedly connected to the outer side of each locking plate. A locking pin is fixedly connected to the end of the spring away from the locking plate. Both locking pins penetrate the locking plate and engage with the sliding frame.

[0007] Preferably, in any of the above embodiments, the inner wall of the sliding frame is fixedly connected to two symmetrically arranged sliding supports, and both sliding supports are slidably connected to the support plate.

[0008] Preferably, from any of the above solutions, locking holes are provided on both the left and right sides of the sliding frame, and the two locking pins pass through the locking plate and engage with the sliding frame through the locking holes.

[0009] Preferably, in any of the above solutions, the top surface of the bottom frame is provided with a plurality of symmetrically arranged connecting grooves, and the connecting plate is slidably connected to the bottom frame through the connecting grooves.

[0010] Preferably, in any of the above solutions, a plurality of linear array anti-slip pads are fixedly connected to the side of the clamping plate near the main body of the electronic device, and the anti-slip pads are made of rubber.

[0011] Preferably, in any of the above solutions, the inner wall of the bottom frame is fixedly connected to two symmetrically arranged guide rods, and both drive plates are slidably connected to the guide rods.

[0012] Preferably, one side of each of the above-mentioned schemes has a threaded hole, and the drive plate is threadedly connected to a bidirectional lead screw through the threaded hole.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. This extended-view naked-eye 3D film bonding assembly effectively solves the problem of difficult replacement of traditional limiting frames through its structural design of locking plates, springs, and locking pins. When it is necessary to replace the film bonding limiting frame, simply pull the locking pin outward to compress the spring, causing the locking pin to disengage from the locking hole of the sliding frame, thus releasing the locking plate from fixing the film bonding limiting frame and easily removing it from the sliding frame. When installing a new limiting frame, place it between the two locking plates, release the locking pin, and the spring returns to its original position, pushing the locking pin back into the locking hole for quick installation. This design eliminates the need for tools to remove screws or complex structural modifications, significantly shortening the limiting frame replacement time, improving production flexibility, and enabling the bonding assembly to quickly adapt to electronic device bodies of different sizes and shapes and naked-eye 3D films, reducing equipment precision loss caused by limiting frame replacement.

[0014] 2. The device achieves precise clamping and bonding position adjustment of the electronic device body through a linkage structure of a bidirectional lead screw, a drive plate, and a clamping plate. Rotating the bidirectional lead screw causes two opposing threads on its outer surface to simultaneously drive two symmetrically arranged drive plates to slide in opposite directions along the guide rod, moving the connecting plate and clamping plate to tightly clamp electronic device bodies of different sizes. Rubber anti-slip pads on the clamping plate increase friction, preventing the device from sliding or shifting during bonding. Simultaneously, the sliding frame can slide up and down along the support plate; its position can be fixed by tightening the locking bolts, achieving precise vertical alignment between the film-mounted limit frame and the electronic device body. The lateral position can be adjusted by moving the drive plate. This multi-dimensional adjustment function allows the bonding components to flexibly adapt to different device specifications, ensuring precise alignment of the naked-eye 3D film with the screen during bonding, improving bonding quality and efficiency.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0018] like Figures 1 to 4 As shown, a naked-eye 3D film bonding assembly with extended viewing angle includes a base frame 1 and an electronic device body 2. A bidirectional lead screw 3 is rotatably connected to the inner wall of the base frame 1 via bearings. Two symmetrically arranged drive plates 4 are threaded onto the outer surface of the bidirectional lead screw 3. Two symmetrically arranged connecting plates 5 are fixedly connected to the top surface of each drive plate 4. A clamping plate 6 is fixedly connected between the two connecting plates 5. The electronic device body 2 is located between the two clamping plates 6. A support plate 7 is fixedly connected to the top surface of the base frame 1. A sliding frame 8 is slidably connected to the outer surface of the support plate 7. The front of the slide frame 8 is threaded with a locking bolt 9. The threaded part of the locking bolt 9 is in contact with the support plate 7. The left and right sides of the slide frame 8 are slidably connected with locking plates 10. A film-applying limiting frame 11 is fixedly connected between the two locking plates 10. The limiting frame 11 is slidably connected to the support plate 7. The film-applying limiting frame 11 corresponds vertically to the main body 2 of the electronic device. A spring 12 is fixedly connected to the outside of each locking plate 10. A locking pin 13 is fixedly connected to the end of the spring 12 away from the locking plate 10. Both locking pins 13 pass through the locking plate 10 and are engaged with the slide frame 8.

[0019] As an optional technical solution of this utility model, the inner wall of the sliding frame 8 is fixedly connected with two symmetrically arranged sliding supports 14. Both sliding supports 14 are slidably connected to the support plate 7. The two symmetrically arranged sliding supports 14 are embedded in the surface of the support plate 7. When adjusting the height of the sliding frame 8, it can effectively prevent the sliding frame 8 from tilting or shaking, and ensure that the film-applying limiting frame 11 always remains horizontal during the movement.

[0020] As an optional technical solution of this utility model, locking holes 15 are provided on both the left and right sides of the sliding frame 8. Two locking pins 13 pass through the locking plate 10 and are engaged with the sliding frame 8 through the locking holes 15. When the locking pins 13 pass through the locking plate 10 and are inserted into the locking holes 15, the locking plate 10 and the sliding frame 8 can be firmly connected, thereby fixing the position of the film-applying limiting frame 11 and preventing it from shifting during the application process.

[0021] As an optional technical solution of this utility model, a plurality of symmetrically arranged connecting grooves 16 are provided through the top surface of the bottom frame 1. The connecting plate 5 is slidably connected to the bottom frame 1 through the connecting grooves 16. The connecting plate 5 slides along the connecting grooves 16. When the bidirectional lead screw 3 drives the drive plate 4 to move, it can effectively prevent the connecting plate 5 from shifting or jamming, so that the two clamping plates 6 can clamp the electronic device synchronously and stably. At the same time, the limiting effect of the connecting grooves 16 on the connecting plate 5 enhances the overall rigidity of the clamping structure, prevents the connecting plate 5 from deforming due to uneven force during the clamping process, and ensures the reliability and stability of clamping the electronic device.

[0022] As an optional technical solution of this utility model, a number of linear array anti-slip pads 17 are fixedly connected to the side of the clamping plate 6 near the main body 2 of the electronic device. The anti-slip pads 17 are made of rubber. The rubber anti-slip pads 17 have good flexibility and friction. When the clamping plate 6 clamps the electronic device, the anti-slip pads 17 can closely adhere to the surface of the device, increase the contact area, and prevent the device from sliding or shifting due to external forces (such as the pressure when applying the film) during the bonding operation.

[0023] As an optional technical solution of this utility model, the inner wall of the bottom frame 1 is fixedly connected with two symmetrically arranged guide rods 18, and the two drive plates 4 are slidably connected to the guide rods 18. The symmetrical arrangement of the two guide rods 18 restricts the movement trajectory of the drive plates 4, so that they can only slide along the axial direction of the lead screw 3, effectively preventing the drive plates 4 from rotating or shifting laterally during movement.

[0024] As an optional technical solution of this utility model, each drive plate 4 has a threaded hole 19 through one side. The drive plate 4 is threadedly connected to the bidirectional lead screw 3 through the threaded hole 19. When the bidirectional lead screw 3 rotates, the drive plate 4 can move linearly along the axial direction of the lead screw 3 through the cooperation of the threaded hole 19 and the lead screw 3. The threaded connection method has high transmission accuracy and can accurately control the moving distance of the drive plate 4, thereby precisely adjusting the position of the clamping plate 6 to adapt to the electronic device body 2 of different sizes.

[0025] A naked-eye 3D film bonding component with expanded field of view works as follows: 1) When it is necessary to replace the film-applying limit frame 11, simply pull the locking pin 13 outward to compress the spring 12, so that the locking pin 13 disengages from the locking hole 15 of the slide frame 8, thereby releasing the locking plate 10 from fixing the film-applying limit frame 11.

[0026] 2): Easily remove it from the slide frame 8; when installing a new limit frame, place it between the two locking plates 10, release the locking pin 13, the spring 12 returns to its original position and pushes the locking pin 13 back into the locking hole 15, completing the quick installation.

[0027] 3): Rotating the bidirectional lead screw 3, the two reverse threads on its outer surface can synchronously drive the two symmetrically arranged drive plates 4 to slide in opposite directions along the guide rod 18, thereby driving the connecting plate 5 and the clamping plate 6 to move, thus tightly clamping the electronic device body 2 of different sizes.

[0028] In summary, this naked-eye 3D film bonding assembly with expanded viewing angle effectively solves the problem of difficult replacement of traditional limiting frames through the structural design of locking plate 10, spring 12, and locking pin 13. When it is necessary to replace the film limiting frame 11, simply pull the locking pin 13 outward to compress the spring 12, causing the locking pin 13 to disengage from the locking hole 15 of the slide frame 8, thereby releasing the locking plate 10 from fixing the film limiting frame 11 and easily removing it from the slide frame 8; when installing a new limiting frame, place it between the two locking plates 10, release the locking pin 13, and the spring 12 will reset and push the locking pin 13 back into the locking hole 15, completing the quick installation. This design eliminates the need for tool-assisted screw removal or complex structural modifications, significantly reducing the replacement time of the limiting frame and improving production flexibility. It allows the bonding components to quickly adapt to electronic device bodies 2 and naked-eye 3D films of different sizes and shapes, minimizing equipment precision loss due to limiting frame replacements. Through the linkage structure of the bidirectional lead screw 3, drive plate 4, and clamping plate 6, precise clamping and bonding position adjustment of the electronic device body 2 are achieved. Rotating the bidirectional lead screw 3 causes its two reverse threads on its outer surface to simultaneously drive two symmetrically arranged drive plates 4 to slide in opposite directions along the guide rod 18, moving the connecting plate 5 and clamping plate 6 to tightly clamp electronic device bodies 2 of different sizes. The rubber anti-slip pads 17 on the clamping plate 6 increase friction, preventing the equipment from sliding or shifting during bonding. Simultaneously, the sliding frame 8 can slide up and down along the support plate 7. The position of the sliding frame 8 can be fixed by tightening the locking bolt 9, achieving precise vertical alignment between the film-applying limiting frame 11 and the electronic device body 2; the lateral position can be adjusted by moving the drive plate 4. This multi-dimensional adjustment function allows the bonding components to flexibly adapt to devices of different specifications, ensuring that the naked-eye 3D film remains precisely aligned with the screen during the bonding process, thus improving bonding quality and efficiency.
