Description

Technical Field

[0001] This invention relates to the field of film application equipment technology, and in particular to a high-precision film application equipment for flexible display panels. Background Technology

[0002] With the rapid development of smart electronic terminal designs, the shift from flat to curved panels offers users a novel experience. In curved touch display panels, curved protective glass or curved support glass is an indispensable component. Generally, the surface of the curved glass is coated with a flexible optical adhesive and a drive unit for reciprocating movement of the base relative to the workpiece. The base contains two symmetrically arranged, vertically parallel housings. Inside each housing is a film-applying assembly for applying a film. The film-applying assembly includes a bracket that slides with the housing, and a film-applying roller that is rotatably installed inside the bracket. The film-applying roller is hollow and contains an auxiliary component. The auxiliary component generates negative pressure when the film-applying rollers move away from each other to increase the film-applying effect, and generates airflow when the film-applying rollers move closer together to remove dust.

[0003] Preferably, the auxiliary component includes a vent, a rotating rod, a shifting groove, and a shifting block; the vent is provided in multiple ways, and the multiple vents are distributed on the surface of the application roller; the application roller is provided with rotating rods on both sides; a shifting block is rotatably provided at one end of the rotating rod; the shifting block is hollow; the rotating rod seals and connects the shifting block and the application roller; the shifting block is slidably connected to the shifting groove.

[0004] Preferably, the auxiliary component further includes a fixed rod, a piston plate, an elastic element, and a through hole; the bottom of the fixed rod passes through the moving block and is slidably sealed; the piston plate is fixedly provided at the end of the fixed rod; the elastic element is provided at the bottom of the piston plate and the lower inner side of the moving block; the through hole is provided at the bottom of the moving block; when the housing presses down and moves to both sides to apply the film, the applying roller drives the moving block to move upward relative to the moving groove, and the fixed rod moves downward relative to the moving block; the space inside the moving block corresponding to the rotating rod increases; the rotating rod connects to the applying roller to generate an inward airflow, increasing the force between the film and the applying roller, resulting in a better film application effect and a smoother application; when the housing moves upward and gradually approaches, the force on the applying roller from the workpiece gradually decreases, the moving block moves in the opposite direction, and an outward airflow is generated in the vent hole of the applying roller to blow away the dust on the film, further increasing the film application effect.

[0005] The device includes a base and a drive component for reciprocating the base relative to a workpiece. The base has two housings symmetrically arranged and vertically parallel inside, each housing contains a film-applying assembly for applying film. The housing also has a guide component that engages with the film-applying assembly. When the film-applying assembly contacts the workpiece, it can move in the opposite direction relative to the housing. At this time, the guide component can drive the two film-applying assemblies to move closer together. When the two film-applying assemblies contact each other, the two housings can be driven to switch from a vertically parallel state to a relatively open state.

[0006] As a further aspect of the present invention: the film application assembly includes a bracket that slides with the housing, an application roller is rotatably installed inside the bracket, a first spring is fixedly installed on the top of the bracket, the end of the first spring away from the bracket abuts against the inner wall of the housing, and a guide post is rotatably installed on the surface of the bracket that engages with the guide assembly. The bracket can be moved along the length of the housing through the guide post and the guide assembly.

[0007] As a further aspect of the present invention: the guide component is an inclined groove formed on the inner wall of the housing, the inclined groove is adapted to the size of the guide post and is movably engaged, and the inclined grooves on the two housings are arranged in a figure-eight shape; when the guide post rises along the inclined groove, the guide posts on the two housings tend to move towards the middle, and eventually make the two supports fit together in contact.

[0008] As a further aspect of the present invention: the guiding component includes a first inclined section, a second inclined section and a converging section connected sequentially from bottom to top, with the first inclined section and the second inclined section having opposite inclination directions; when the guide post enters the second inclined section along the first inclined section, it can drive the applicator roller to move horizontally reciprocally along the width direction of the housing.

[0009] As a further aspect of the present invention: the first inclined section and the second inclined section on the two housings are arranged in parallel, and the converging sections on the two housings are arranged in a figure-eight shape. When the two guide posts enter the corresponding converging sections, they tend to move towards the middle.

[0010] As a further aspect of the present invention: the junction of the first inclined segment and the second inclined segment is located near the adjacent side of the two shells.

[0011] As a further aspect of the present invention, the spacing between the two vertices of the converging segments is set to be smaller than the width of the support.

[0012] As a further aspect of the present invention: a telescopic rod is fixedly installed on the surface of the bracket, and a sliding groove is provided inside the housing for the fixed end of the telescopic rod to slide, so that the bracket can move along the width direction of the housing.

[0013] Compared with existing technologies, the advantages of this invention are as follows: Through the cooperation between the base, housing, film-applying assembly, and guiding assembly, the two housings can be transformed from a vertically parallel state to a relatively open state, and the opening angle can be further increased. During the opening process, the film-applying assembly can be moved synchronously, allowing it to move from the middle to both sides to complete the film application. This effectively reduces air bubble accumulation and ensures a smooth film application. The ability of the film-applying assembly to move along the housing not only buffers the workpiece to prevent damage but also provides driving force for subsequent housing state switching. The overall structure is simple and more practical. Attached Figure Description

[0029] Example 1:

[0030] Please see Figures 1 to 2 This invention provides a high-precision film application device for flexible display panels, mainly used to achieve effective film application on curved screens and ensure film application quality. The device includes a base 1 and a driving component 5 for driving the base 1 to reciprocate in the up-down direction. The driving component 5 is fixedly connected to the worktable during use and is set on the top of the base 1. It can be implemented using existing electric push rods, cylinders or reciprocating lead screws, etc., which are all existing mature technologies and will not be described in detail here.

[0031] Two symmetrically arranged shells 2 are rotatably mounted inside the base 1. Under gravity, the shells 2 are vertically aligned side-by-side. Inside each shell 2 is a film-applying assembly 3 for applying the film. A guide assembly 4 is also provided inside the shell 2 to engage with the film-applying assembly 3. When the drive unit 5 lowers the base 1 and shells 2, the two shells 2 initially move downwards in a vertically aligned position. When the film-applying assembly 3 contacts the workpiece, it can move in the opposite direction relative to the shells 2 under the influence of the workpiece. At this time, the guide assembly 4 can guide the two film-applying assemblies 3 to move closer together. Once the two film-applying assemblies 3 contact, the two shells 2 can switch from a vertically aligned position to a relatively open position (with the base 1 as the base point). As the drive unit 5 continues to lower the base 1, the opening angle of the two shells 2 gradually increases. During this gradual opening process, the shells 2 drive the film-applying assembly 3 to move synchronously, completing the effective application of film to the workpiece.

[0032] In this embodiment, the fixture for placing the workpiece and the worktable for supporting the fixture are not shown in the figure. They are both existing mature technologies and will not be described in detail here. It can be understood that the fixture is located directly below the drive member 5, so that the drive member 5 drives the base 1 to descend to the center of the workpiece. The worktable is also used to fix the drive member 5.

[0033] Please see Figures 1 to 4In this embodiment, preferably, the film-applying assembly 3 includes a bracket 301 that slides left and right with the housing 2. The bracket 301 has a U-shaped design with its opening facing downwards. An applicator roller 302 is rotatably mounted inside the bracket 301. A first spring 303 located inside the housing 2 is fixedly mounted on the top of the bracket 301. The end of the first spring 303 away from the bracket 301 abuts against the inner top wall of the housing 2, but the two are not fixedly connected. Under the action of the first spring 303, the bracket 301 has a downward tendency to move away from the housing 2. A guide post 304 is rotatably mounted at the front / rear end of the bracket 301 and engages movably with the guide assembly 4. The guide post 304 and the guide assembly 4 can also realize the up-and-down sliding of the bracket 301 relative to the housing 2.

[0034] In this embodiment, a telescopic rod 202 is fixedly installed at the end of the bracket 301 near the housing 2. The housing 2 has an internal groove 201 for sliding the fixed end of the telescopic rod 202. The telescopic rod 202 reciprocates left and right, allowing the bracket 301 to move left and right relative to the housing 2. The groove 201 allows the telescopic rod 202 to move up and down, thus enabling the bracket 301 to move up and down relative to the housing 2. Alternatively, the telescopic rod 202 and the groove 201 can be positioned on the side of the bracket 301 away from the guide post 304.

[0035] Furthermore, the guide component 4 is an inclined groove formed on the inner wall of the housing 2. The inclined groove is adapted to the size of the guide post 304 and is movably engaged. The inclined grooves on the two housings 2 are arranged in a figure-eight shape, so that when the bracket 301 drives the guide post 304 to rise along the inclined groove, the guide post 304 drives the bracket 301 to tend to move towards the middle. When the two brackets 301 come into contact, they automatically open the two housings 2 that were originally in a vertical parallel state, so that they turn into a relatively open state.

[0036] In use, the drive unit 5 lowers the base 1 and the two vertically aligned housings 2 (the film needs to be placed on the workpiece first). When the application roller 302 contacts the workpiece, it drives the support 301 to rise relative to the housing 2. Under the action of the guide post 304 and the inclined groove, the two supports 301 drive the application roller 302 to move closer together, allowing for the application of film to the middle portion of the workpiece. As the support 301 continues to rise, when the two supports 301 contact each other, they can cause the two housings 2 to open to both sides based on the base 1 (e.g., ...). Figure 4 As shown in the figure, as the driving component 5 drives the base 1 to continue to descend, the two housings 2 can further expand the opening angle. During the opening process, the bracket 301 and the coating roller 302 move synchronously, which can realize the effective coating of the workpiece. Moreover, the coating method of moving from the middle to both sides can effectively reduce the air content and ensure the flatness of the coating.

[0037] In summary, through the cooperation of structures such as the inclined groove, bracket 301, housing 2, and coating roller 302, the two housings 2 can be transformed from vertically parallel to relatively open, and the opening angle can be further increased. During the opening process, the coating roller 302 can be driven to move synchronously, enabling the coating roller 302 to move from the middle to both sides to complete the film application. This effectively reduces the hiding of air bubbles and ensures a smooth film application. The design of the first spring 303 driving the bracket 301 not only buffers the coating roller 302 relative to the workpiece to avoid damage, but also allows the bracket 301 to move closer together, thereby driving the housing 2 to move. The overall structure is simple and has higher practicality.

[0038] Example 2:

[0039] Please see Figures 1 to 5 Based on Embodiment 1, in order to further ensure the quality of film application, the guide component 4 has been improved. The guide component 4 includes a first inclined section 401, a second inclined section 402 and a converging section 403 connected sequentially from bottom to top. The first inclined section 401 and the second inclined section 402 are in opposite directions, so that the guide post 304 forms a left-right reciprocating motion when passing through the first inclined section 401 and the second inclined section 402.

[0040] At the same time, the converging sections 403 on the two shells 2 are arranged in a figure-eight shape, so that the guide posts 304 on the two shells 2 eventually return to the tendency to move towards the middle, thereby completing the process of driving the bracket 301 to move towards the middle.

[0041] Please see Figures 1 to 7 In this embodiment, preferably, the first inclined segment 401 is designed to be inclined from left to right and upward, and the second inclined segment 402 is designed to be inclined from right to left and upward. Of course, the directions of the first inclined segment 401 and the second inclined segment 402 can be interchanged, which can also achieve the process of driving the guide post 304 to move back and forth. It is only necessary to interchange the direction of the approaching segment 403 as well.

[0042] Furthermore, the junction of the first inclined section 401 and the second inclined section 402 can be set as close as possible to the adjacent side of the two housings 2 (i.e., the right side of the left housing 2 and the left side of the right housing 2), so that the guide post 304 can drive the bracket 301 and the coating roller 302 to better coat the middle part of the workpiece.

[0043] It should be noted that the spacing between the vertices of the two converging segments 403 needs to be set to be smaller than the width of the bracket 301, so that when the guide post 304 enters above the converging segment 403, the two brackets 301 can form a close contact.

[0044] It should be noted that the guide components 4 on the two housings 2 can have the same length in the vertical direction, so that the two guide posts 304 can make contact between the two housings 2 when they reach the apex of the converging section 403; the first inclined section 401, the second inclined section 402, and the converging section 403 are adapted to the dimensions of the guide posts 304 and are movably engaged. Furthermore, the sidewalls of the housings 2 are provided with clearance grooves 203 to allow for the reciprocating movement of the bracket 301 and the applicator roller 302.

[0045] In use, the support 301 and housing 2 drive the two housings 2 to descend vertically side by side, and then open relative to each other, causing the support 301 and the application roller 302 to move synchronously. The application of film is achieved through the movement and rotation of the application roller 302. This part of the working process and effect is the same as in Embodiment 1, and will not be repeated here. The difference is that when the application roller 302 contacts the workpiece and drives the support 301 to rise relative to the housing 2, the guide post 304 drives the support 301 to move to the right along the first inclined section 401, then to the left along the second inclined section 402, and finally to the closing section 403, causing the two housings 2 to move towards the middle and thus drive the two housings 2 to open.

[0046] In Embodiment 1, the support 301 and housing 2 can drive the application roller 302 to move from the middle to both sides to complete the film application. However, due to the circular design of the application roller 302, the workpiece is located in the middle part of the two application rollers 302 and fails to make good contact with the application roller 302. That is, the film application quality of the workpiece in the middle part of the two application rollers 302 cannot be guaranteed, which has certain limitations in use.

[0047] Compared to Embodiment 1, through the cooperation of the guide post 304, the first inclined section 401, the second inclined section 402, and the converging section 403, when the applying roller 302 contacts the workpiece, it can first move left and right back and forth, and then move towards the center so that the two supports 301 contact each other. This achieves effective film application to the middle part of the workpiece, ensuring more reliable overall film application quality. The overall design of the guiding component 4 is further improved without affecting the movement and subsequent contact of the support 301, making it more versatile.

[0048] Example 3:

[0049] Please see Figures 1 to 8 Based on Embodiment 2, to further avoid damage to the workpiece, an adjustment component 6 corresponding to the upper position of the approaching section 403 is slidably installed inside the housing 2. When the two housings 2 are vertically side by side, the adjustment components 6 are also adjacent and close together. When the two housings 2 are relatively open, the adjustment components 6 on the two housings 2 can slide and overlap with the corresponding approaching section 403 in the front-back direction. After the adjustment components 6 slide and overlap, the guide post 304 inside the approaching section 403 can be effectively limited, so that the bracket 301 and the applicator roller 302 can no longer move downward.

[0050] Please see Figures 1 to 10 In this embodiment, preferably, the adjusting component 6 includes a slider 601 that slides with the housing 2. A stop bar 602 is rotatably mounted on the surface of the slider 601 near the corresponding abutment section 403. The stop bar 602 is configured to rotate only 90 degrees. The left stop bar 602 can only rotate 90 degrees clockwise from a horizontal position, and the right stop bar 602 can only rotate 90 degrees counterclockwise from a horizontal position. The above process can also be implemented using a torsion spring. A second spring 603 is fixedly installed between the slider 601 and the housing 2. Under the action of the spring, the slider 601 has a tendency to move towards the corresponding abutment section 403.

[0051] To facilitate the adjacent contact of the two sliders 601, both sliders 601 are made of magnetic material with opposite magnetic poles. This allows the two sliders 601 to adhere to each other when the two shells 2 are side by side, and to move away from each other under the action of the corresponding second spring 603 when the two shells 2 are opened. Based on the magnetic design, the two shells 2 can also maintain a stable vertical side by side in the initial state, thus achieving multiple benefits.

[0052] In the above structure, the slider 601 and the stop bar 602 are all staggered with the bracket 301, so as not to affect the movement of the bracket 301 relative to the housing 2, and not to interfere with the movement of the guide post 304 along the guide assembly 4.

[0053] Furthermore, the surface of the housing 2 is provided with a groove 204 for the placement of the slider 601. Under the action of the groove 204, the slider 601 can slide horizontally left and right along the housing 2.

[0054] In use, the bracket 301 and housing 2 drive the two housings 2 to descend vertically side by side and then open relative to each other. The first inclined section 401 and the second inclined section 402 enable the roller 302 to move back and forth left and right and then move towards the center. The working process and effect of this part are the same as in embodiment 2, and will not be repeated here. The difference is that when the guide column 304 rises along the closing section 403 to the top, the two brackets 301 close together and drive the two housings 2 to open relative to each other. At this time, the two sliders 601 also separate synchronously. Under the action of the second spring 603, the sliders 601 drive the stop bar 602 to move towards the corresponding closing section 403. The rotating stop bar 602 does not affect the continued rise of the guide column 304, but the guide column 304 cannot descend freely after rising. At this time, the bracket 301 can maintain the rising state relative to the housing 2, and the two housings 2 can also maintain the relative opening state.

[0055] In Embodiment 2, the guide post 304 and the converging section 403 can achieve the reciprocating motion of the application roller 302 from left to right and then converging towards the center. However, after the application roller 302 completes the application of film to the workpiece, it will instantly reset under the action of the first spring 303 after separating from the workpiece. This causes the application roller 302 to forcefully squeeze the two sides of the workpiece after film application, which will cause compression to the flexible curved screen and affect the film application quality, thus having certain limitations in use.

[0056] Compared to Embodiment 2, through the cooperation of the slider 601, stop bar 602, guide post 304, and second spring 603, when the guide post 304 rises to its apex along the converging section 403, the stop bar can slide to limit the guide post 304, preventing the guide post 304 from instantly resetting and causing the application roller 302 to return to its original position. This avoids squeezing the edge of the curved screen and ensures the quality of the film application. It can also be quickly and manually removed later. The overall structure of the housing 2 has been further designed to ensure reliable film application quality and meet more needs in actual use.

[0057] As a further improvement to this embodiment: Subsequently, if manual release is not desired, a magnetic block (not shown in the figure) can be fixedly fitted onto the worktable. The two magnetic poles of the magnetic block are respectively set opposite to the magnetic poles of the two sliders, so that when the driving component 5 drives the base 1 and the housing 2 to reset, the sliders 601 on the two relatively open housings 2 will attract the magnetic block, thereby driving the two sliders 601 to move closer to each other to release the restriction on the guide post 304, so that the guide post 304 drives the bracket 301 to descend and reset along the guide component 4, and finally the two housings 2 return to the vertical parallel state.

[0058] Example 4:

[0059] like Figure 11-13 A high-precision film-applying device for flexible display panels includes a base 1 and a driving component 5 for driving the base 1 to reciprocate relative to a workpiece. Two housings 2, symmetrically arranged and vertically aligned, are rotatably mounted inside the base 1. A film-applying assembly 3 for completing the film application is disposed inside the housings 2. The film-applying assembly 3 includes a bracket 301 that slides with the housings 2. A film-applying roller 302 is rotatably mounted inside the bracket 301. The film-applying roller 302 is hollow and also contains an auxiliary component 7. The auxiliary component 7 generates negative pressure to enhance the film-applying effect when the film-applying rollers 302 move away from each other, and generates airflow to remove dust when the film-applying rollers 302 move closer together.

[0060] Specifically, the auxiliary component 7 includes a vent 701, a rotating rod 702, a shifting groove 703, and a shifting block 705; multiple vents 701 are provided, and the multiple vents 701 are distributed on the surface of the applicator roller 302; rotating rods 702 are provided on both sides of the applicator roller 302; a shifting block 705 is rotatably provided at one end of the rotating rod 702; the shifting block 705 is hollow; the rotating rod 702 seals and connects the shifting block 705 and the applicator roller 302; the shifting block 705 is slidably connected to the shifting groove 703.

[0061] Specifically, the auxiliary component 7 further includes a fixing rod 704, a piston plate 706, an elastic element 707, and a through hole 708; the bottom of the fixing rod 704 passes through the moving block 705 and is slidably sealed; the piston plate 706 is fixedly mounted at the end of the fixing rod 704; the elastic element 707 is located between the bottom of the piston plate 706 and the lower inner side of the moving block 705; the through hole 708 is located at the bottom of the moving block 705; when the housing 2 presses down to both sides to apply the film, the applying roller 302 drives the moving block 706. 5. The relative shifting groove 703 moves upward, and the fixed rod 704 moves downward relative to the shifting block 705. The space inside the shifting block 705 corresponding to the rotating rod 702 increases. The rotating rod 702 connects to the application roller 302 to generate an inward airflow, which increases the force between the film and the application roller 302, resulting in a better film application effect and a smoother application. When the housing 2 moves upward and gradually approaches, the force on the application roller 302 from the workpiece gradually decreases, and the shifting block 705 moves in the opposite direction. An outward airflow is generated in the vent hole 701 of the application roller 302 to blow away the dust on the film, further improving the film application effect.
