Technical Field

[0001] This invention relates to the field of film application technology, and in particular to a vacuum film application device and a vacuum film application method. Background Technology

[0002] Currently, in the field of automation, with the rise and popularization of VR technology, the demand for products such as VR glasses is increasing. The lenses of VR glasses typically require a protective film to prevent scratches that could affect the visual experience. Furthermore, the quality of the film application affects the lens's transmission effect, ultimately impacting the VR glasses' imaging quality. To ensure the final imaging effect, the requirements for the quality of the lens film application are becoming increasingly stringent. Manual film application has low precision and efficiency, and is prone to the accumulation of dust and other impurities between the film and the lens, affecting the overall quality of the application.

[0003] In addition, in existing vacuum lamination devices, the robotic arm places the lens directly onto the film. Since the contact process between the lens and the film generates an impact force, it can easily damage the lens or the film.

Furthermore, when the pressure buffer moves upward by the preset distance, it can abut against the stop portion of the rotating plate.

[0021] Preferably, the transfer assembly includes a pressure sensor disposed between the pressure buffer and the rotating plate.

[0026] The beneficial effects of this invention are as follows:

[0027] This invention provides a vacuum film application device and a vacuum film application method. The vacuum film application device is used to apply a first workpiece and a second workpiece. The vacuum film application device includes a worktable, a first moving component, a first sealing component, a second moving component, a transfer component, and a second sealing component. The first moving component includes a first moving plate, which is slidably disposed on the worktable along a first direction. The first sealing component is disposed on the first moving plate.

[0028] This vacuum film-applying device achieves automated film and lens bonding through the configuration of a moving component, improving bonding efficiency and accuracy. The first moving component allows a first sealing component mounted on a first moving plate to move along a first direction and dock with a second sealing component, forming a sealed cavity. Since at least one first vent is provided between them, a vacuum can be drawn into the sealed cavity. Then, the second moving plate is moved, bringing the lens on the transfer component closer to and contacting the film on the stage, completing the bonding under vacuum. The vacuum environment eliminates static electricity on the lens and film, preventing dust contamination and ensuring a dust-free environment between the film and lens. Furthermore, by sliding the transfer component within a preset distance along the first direction on the second moving plate, the lens moves upwards at the moment of contact with the film, greatly reducing the impact force between them and improving the safety of the lens and film.

[0050] Embodiments of the present invention are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0051] Example 1

[0052] With the rise and popularization of VR technology, the demand for VR glasses and other products is increasing. VR glasses lenses typically require a protective film to prevent scratches that could affect the visual experience. The quality of the film application also affects the lens's transmission efficiency, ultimately impacting the VR glasses' imaging performance. To ensure optimal imaging, the quality requirements for lens film application are becoming increasingly stringent. Manual film application is both inaccurate and inefficient, and dust and other impurities can easily accumulate between the film and the lens, affecting the application quality. In existing vacuum film application devices, a robotic arm places the lens directly onto the film. However, the contact between the lens and the film generates an impact force, which can easily damage either the lens or the film.

[0053] Therefore, such as Figure 1-6 As shown, this embodiment provides a vacuum film-applying device for attaching a first workpiece and a second workpiece. In this embodiment, the first workpiece and the second workpiece can be a lens 100 and a film 200, respectively. Of course, they can be other two workpieces that need to be attached or bonded. This embodiment only uses the above-mentioned components as examples for detailed explanation, but it is not limited to this. In this embodiment, the vacuum film-applying device includes a worktable 1, a first moving assembly 2, a first sealing assembly 3, a second moving assembly 4, a transfer assembly 5, and a second sealing assembly 6. The first moving assembly 2 includes a first moving plate 21, which is slidably disposed on the worktable 1 along the first direction Z. The first sealing assembly 3 is disposed on the first moving plate 21. The second moving assembly 4 includes a second driving member and a second moving plate 41, which is slidably disposed inside the first sealing assembly 3 along the first direction Z. The second driving member is disposed on the second sealing assembly 6 and is connected to the second moving plate. 41. Transmission connection; the transfer component 5 is slidably disposed on the second moving plate 41 within a preset distance along the first direction Z, for transferring the lens 100; the second sealing component 6 is disposed on the worktable 1, and a carrier 62 is provided inside the second sealing component 6, the carrier 62 is used to support the film 200; when the first sealing component 3 and the second sealing component 6 are docked, a sealing cavity is formed between the first sealing component 3 and the second sealing component 6, at least one of the first sealing component 3 and the second sealing component 6 is provided with a first air hole 611, the first air hole 611 is connected to the sealing cavity, and is used to extract internal air. In this embodiment, preferably, the first air hole 611 is disposed on the second sealing component 6, this arrangement facilitates the connection of the gas pipeline and is beneficial to the extraction of air. The first moving component 2 and the second moving component 4 can both be linear modules.

[0054] In this embodiment, the vacuum film-applying device achieves automated bonding of the film 200 and the lens 100 through the arrangement of the first moving component 2 and the second moving component 4, improving the efficiency and accuracy of film application. By setting the first moving component 2, the vacuum film-applying device enables the first sealing component 3 mounted on the first moving plate 21 to move along the first direction Z and dock with the second sealing component 6, forming a sealed cavity between the first sealing component 3 and the second sealing component 6. Since at least one first air hole 611 is provided between them, the sealed cavity can be evacuated. At this time, the second moving plate 41 is moved so that the lens 100 on the transfer component 5 approaches and contacts the film 200 on the stage 62, so that the film 200 and the lens 100 are bonded under vacuum. The vacuum environment eliminates static electricity on the lens 100 and the film 200, preventing dust from adhering, thus ensuring that there is no dust between the film 200 and the lens 100. Furthermore, by sliding the transfer component 5 within a preset distance along the first direction Z on the second moving plate 41, the lens 100 will move upward at the instant the lens 100 and the film 200 come into contact, which greatly reduces the impact force between the two and improves the safety of the lens 100 and the film 200.

[0055] In this embodiment, the first sealing assembly 3 includes a sealing box 32 and a first sealing element 31. The sealing box 32 has an opening, and the first sealing element 31 is cylindrical. One end of the first sealing element 31 is located in the sealing box 32 and communicates with the opening. The sealing box 32 is located on the first moving plate 21. The transfer assembly 5 is located in the sealing box 32 and can move the first workpiece into the first sealing element 31. The sealing box 32 has a cuboid structure, and its design facilitates the installation of the moving assembly. The cylindrical first sealing element 31 is installed in the sealing box 32. Obviously, the size of the opening is smaller than the cross-sectional area of ​​the sealing box 32, resulting in a smaller mating surface when the second sealing assembly 6 is connected, which facilitates sealing.

[0056] In this embodiment, the sealing box 32 includes multiple detachable plates, which are screwed together to form the sealing box 32. Sealing gaskets are provided at each joint to ensure the overall sealing performance. The sealing box 32 is rectangular in shape, which facilitates design, production and assembly, improves production efficiency and reduces costs.

[0057] In this embodiment, the first sealing element 31 and the sealing box 32 are screwed together. This connection method is simple and low-cost. In other embodiments of this embodiment, the first sealing element 31 and the sealing box 32 can be welded or snap-fitted together, and are not limited thereto. In other embodiments of this embodiment, the sealing box 32 may not be provided. In this embodiment, the first sealing element 31 can be directly fixed to the first moving plate 21; the transfer component 5 is disposed inside the first sealing element 31. Considering the convenience of installing the transfer component 5 and the convenience of sealing the sealing cavity, in this embodiment, the sealing box 32 structure is preferably provided.

[0058] In order to achieve docking with the first sealing element 31, in this embodiment, the second sealing assembly 6 includes a second sealing element 61, which is cylindrical. One end of the second sealing element 61 is disposed on the worktable 1, and the other end of the first sealing element 31 can dock with the other end of the second sealing element 61 to form a sealing cavity. Both the first sealing element 31 and the second sealing element 61 are cylindrical structures.

[0059] Of course, in other embodiments of this example, the second sealing member 61 can be a groove-shaped structure. In this embodiment, the platform 62 may not be provided in the second sealing assembly 6, and the membrane 200 may be placed directly on the workbench 1 or placed at the bottom of the groove inside the second sealing member 61.

[0060] The second sealing assembly 6 includes a sealing ring 63, which is disposed on the second sealing member 61. When the first sealing member 31 and the second sealing member 61 are mated, at least a portion of the sealing ring 63 is located between the first sealing member 31 and the second sealing member 61. The sealing ring 63 improves the sealing performance when the first sealing member 31 and the second sealing member 61 are mated.

[0061] In this embodiment, the second sealing member 61 has an annular groove at one end facing the first sealing member 31, and the sealing ring 63 is partially located within the annular groove. The cross-section of the sealing ring 63 is circular or H-shaped, which ensures stable installation of the sealing ring 63 and prevents it from falling off. Of course, in other embodiments of this embodiment, the cross-section of the sealing ring 63 can be U-shaped, fitted onto one end of the second sealing member 61, with one side of the sealing ring 63 located inside the second sealing member 61 and the other side located outside the second sealing member 61. The top of the sealing ring 63 is located at the end of the second sealing member 61 and can be pressed tightly by the first sealing member 31 and the second sealing member 61.

[0062] The transfer assembly 5 includes a transfer drive 51 and two clamping members 52. The transfer drive 51 is slidably disposed on the second moving plate 41 along the first direction Z, and is used to drive the working ends of the two clamping members 52 to move closer or further apart. The clamping members 52 enable the clamping of the lens 100 and can accommodate lenses 100 of different sizes.

[0063] Regarding the installation method of the clamping member 52, in this embodiment, the transfer drive member 51 includes a gripper cylinder, and two clamping members 52 are disposed at the two output ends of the gripper cylinder. This arrangement is simple in structure and stable in operation. Of course, in other embodiments of this embodiment, the transfer drive member 51 and the clamping members 52 can be replaced with suction cups. Considering the stability of the structure, in this embodiment, the transfer drive member 51 and the clamping members 52 are preferably used as the means of transferring the lens 100, which will be described in detail below.

[0064] Each of the two clamping members 52 is equipped with a clamping slider 53, and a clamping slide rail 54 is located between the two clamping members 52. Both clamping sliders 53 can slide along the clamping slide rail 54. The arrangement of the clamping slide rail 54 and the clamping sliders 53 ensures that the movement directions of the two clamping members 52 remain parallel, avoiding misalignment and improving the accuracy of clamping the lens 100.

[0065] When the distance between the two clamping members 52 is too large, and the outer diameter of the two clamping members 52 is larger than the inner diameter of the second seal 61, damage to the second seal 61 will occur during downward movement. To solve this problem, in this embodiment, a clamping stop block 541 is provided at each end of the clamping slide rail 54. The clamping stop block 541 can limit the maximum distance between the two clamping members 52 to a certain extent, avoiding damage to the first seal 31.

[0066] If the distance between the two clamping members 52 is too small, excessive pressure will be exerted on the lens 100, potentially causing it to break. To address this issue, in this embodiment, the transfer assembly 5 includes a limiting member 55 to limit the minimum distance between the two clamping members 52. Specifically, the limiting member 55 includes a limiting screw. One of the two clamping members 52 has a limiting screw hole, and the limiting screw is screwed into the limiting screw hole. The limiting screw can pass through the limiting screw hole and abut against the other clamping member 52. The above structure is simple, achieves mechanical limiting, and has stable and reliable performance.

[0067] During the film application process, it is sometimes necessary to adaptively adjust the relative angle between the film 200 and the lens 100 according to the shape of the lens 100. Therefore, in this embodiment, the transfer assembly 5 includes a rotation drive 56, which is disposed on the second moving plate 41, and a transfer drive 51 is disposed at the output end of the rotation drive 56. The rotation drive 56 can rotate around the first direction Z. With the help of the rotation drive 56, the lens 100 can rotate around its own axis.

[0068] In this embodiment, the transfer component 5 includes a rotating plate 57 and a pressure buffer 58. The rotating plate 57 is located at the output end of the rotating drive 56, and the pressure buffer 58 is slidably disposed on the rotating plate 57 along the first direction Z. The transfer drive 51 is disposed on the pressure buffer 58. When the pressure buffer 58 moves upward a specified distance, it can abut against the stop portion of the rotating plate 57. In this embodiment, the specified distance can be any distance between 0.5 and 5 cm. The sliding arrangement of the transfer component 5 is achieved by means of the above structure, and the preset sliding distance of the transfer component 5 is achieved by means of the stop portion on the rotating plate 57. In the natural state, the pressure buffer 58 is located at the lowest end. When the lens 100 and the film 200 come into contact, the pressure buffer 58 slides upward. At this time, the second moving plate 41 continues to move downward, causing the pressure buffer 58 to continue to move upward until it abuts against the stop portion and stops moving.

[0069] The rotating plate 57 is L-shaped and includes a horizontal rotating plate 572 and a vertical rotating plate 571 connected to each other. The horizontal rotating plate 572 is connected to the output end of the rotating drive member 56. The pressure buffer member 58 is slidably disposed on the vertical rotating plate 571, and a stop is disposed on the horizontal rotating plate 572. Specifically, the stop is the lower surface of the horizontal rotating plate 572. The horizontal rotating plate 572 cooperates with the rotating drive member 56 on one hand, and on the other hand, it can serve as a stop to stop the pressure buffer member 58, thus saving costs.

[0070] The transfer assembly 5 includes a transfer slide rail and a transfer slider. The transfer slide rail is disposed on the rotating vertical plate 571, and the transfer slider is disposed on the pressure buffer 58. The transfer slider can slide on the transfer slide rail. The transfer slider and transfer slide rail enable smooth sliding of the pressure buffer 58. Alternatively, in other embodiments of this example, a groove can be provided on the rotating vertical plate 571, and a slider can be provided on the pressure buffer 58. This reduces costs and decreases the distance between the pressure buffer 58 and the rotating vertical plate 571. This, in turn, reduces the size of the transfer assembly 5, allowing for a reduction in the inner diameter of the first sealing member 31. This series of dimensional reductions lowers the overall cost of the device.

[0071] In this embodiment, the transfer component 5 includes a buffer elastic element, which is located between the rotating plate 57 and the pressure buffer 58. This buffer elastic element is used to push the pressure buffer 58 upwards, and its elastic force is less than or equal to the sum of the weights of the pressure buffer 58, the gripper cylinder, and the clamping member 52. The buffer elastic element provides a certain degree of support for the pressure buffer 58, the gripper cylinder, and the clamping member 52, further reducing the impact force when the lens 100 and the film 200 come into contact.

[0072] In this embodiment, to facilitate control of the pressure between the lens 100 and the film 200, the transfer assembly 5 may optionally include a pressure sensor 59, which is disposed between the pressure buffer 58 and the rotating plate 57.

[0073] The pressure buffer 58 has a mounting groove at one end near the rotating plate 57, and the pressure sensor 59 is at least partially located within the mounting groove. Specifically, the mounting groove is located at one end of the pressure buffer 58 near the rotating plate 572. The mounting groove makes the pressure sensor 59 more securely installed, preventing damage from external forces in other directions. Furthermore, it reduces the distance between the pressure buffer 58 and the rotating plate 572, thus lowering costs.

[0074] To fix the film 200 to the stage 62, in this embodiment, the stage 62 is provided with an adsorption hole 621 for adsorbing or blowing up the film 200, and the second sealing component 6 is provided with a second air hole 612. The adsorption hole 621 of the stage 62 communicates with the second air hole 612. In this embodiment, when air is drawn from the second air hole 612, the adsorption hole 621 can tightly adhere the film 200. When air is blown through the second air hole 612, the film 200 can be attached to the lens 100 with a certain curvature, and the blowing process makes the film 200 adhere more tightly.

[0075] To ensure the stability of the adsorption of the membrane 200, in this embodiment, a plurality of adsorption holes 621 are provided, and the plurality of adsorption holes 621 are evenly distributed on the bearing surface of the stage 62.

[0076] Optionally, the second sealing element 61 is provided with a third vent (not shown in the figure). The outlet of the third vent is located on the side wall of the second sealing element 61 and can blow air towards the side of the membrane 200 near the lens 100. With this structure, when the sealing cavity is evacuated and the lens 100 moves downward, if there is a small gap between the lens 100 and the membrane 200, the third vent blows air. At this time, the airflow passes through the two opposing surfaces of the membrane 200 and the lens 100, which can remove residual dust and other impurities on the two opposing surfaces, further ensuring that the two are clean before they are bonded together. The size of this gap can be between 0.5 and 2 mm.

[0077] In this embodiment, to improve the movement range of the transfer component 5, the vacuum film-applying device may optionally include a third moving component 7, which includes a third moving plate 71. The third moving plate 71 is slidably disposed on the worktable 1 along the second direction X, and the first moving plate 21 is slidably disposed on the third moving plate 71 along the first direction Z. The third moving component 7 may be a linear module.

[0078] Furthermore, the vacuum film-applying device includes a fourth moving component 8, which includes a fourth moving plate 81 that can slide relative to the worktable 1 along a third direction Y. The second sealing component 6 is disposed on the fourth moving plate 81. The fourth moving component 8 can be a linear module.

[0079] In this embodiment, to facilitate the placement of the lens 100, the vacuum film-applying device includes a carrier 9 for supporting the lens 100, and the carrier 9 is disposed on the fourth moving plate 81. Several lenses 100 can be placed in the carrier 9 at a time. There are two carriers 9 and two second sealing members 61, each carrier 9 and each second sealing member 61 forming a combination, with the carrier 9 and second sealing member 61 in each combination arranged adjacent to each other. With this layout, after the lens 100 in the sealed cavity of the first combination is film-applied, the transfer component 5 releases the lens 100, which is then removed by the robotic arm. Simultaneously, the transfer component 5 moves to the carrier 9 in the second combination to retrieve the lens 100, and then moves the lens 100 to the sealed cavity in the second combination, improving film-applying efficiency. The distance between the carrier 9 and the second sealing member 61 in each combination is short to minimize the movement distance and avoid contamination by dust and other impurities. The film 200 needs to be placed on the stage 62 by the robotic arm, and one film is placed at a time.

[0080] Example 2

[0081] This embodiment also provides a vacuum film application method. Specifically, the first moving component 2 moves the first moving plate 21 to drive the first sealing component 3 and the second sealing component 6 to dock. At this time, there is a certain distance between the lens 100 and the film 200. After docking, the sealing cavity is evacuated through the first air hole 611. After evacuation, the second moving plate 41 moves downward so that the lens 100 contacts the film 200 and completes the bonding.

[0082] Furthermore, the stage 62 is provided with an adsorption hole 621 for adsorbing or blowing up the membrane 200, and the second sealing component 6 is provided with a second air hole 612. The adsorption hole 621 of the stage 62 is connected to the second air hole 612.

[0083] Based on the above structure, after the film 200 and the lens 100 come into contact, the second vent 612 is opened, and air is blown onto the film 200 through the second vent 612. At this time, the film 200 will move towards the lens 100. With the help of this air force, the film 200 can be attached to the lens 100 which has a certain curvature.

[0084] Furthermore, after the film 200 is applied to the lens 100, the second vent 612 is closed and the first vent 611 is opened for another vacuum treatment. At this time, the air bubbles between the film 200 and the lens 100 can be effectively extracted, which improves the quality of the film application.

[0085] Furthermore, when the film 200 and the lens 100 are not in contact, air is blown through the third vent to remove impurities from both.
