Description

[0001] This invention is a divisional application of Chinese invention patent application No. 202210443291.6, filed on April 26, 2022, entitled "An Array-type Automatic Lens Alignment Film Applying Device". Technical Field

[0002] This invention relates to the field of lens coating equipment technology, and in particular to an array-type automatic alignment lens coating equipment. Background Technology

[0003] With the rise and popularization of VR technology, the demand for VR glasses and other products is increasing. The surface of VR glasses lenses usually needs to be coated. The quality of the coating will affect the transmission effect of the lens and ultimately affect the imaging effect of VR glasses.

[0004] To ensure the final imaging effect, the requirements for the quality of lens coating are becoming increasingly higher. For irregularly shaped lenses (i.e., non-circular lenses), it is necessary to calibrate and attach the irregularly shaped lens to the optical axis of the lens coating to ensure that the optical axis of the lens coating is aligned with the predetermined angle of the irregularly shaped lens. Therefore, the angle of the lens needs to be adjusted during the coating process. Manual adjustment is usually less accurate and efficient.

[0005] Since lens films are typically larger than lenses, one lens film can be applied to multiple lenses during the application process to improve efficiency. If a device could be used to independently adjust the height and angle of multiple irregularly shaped lenses, ensuring that their surfaces are at the same height and facing the same direction, multiple irregularly shaped lenses could be arranged in an array. Simultaneously adjusting the angle of the lens film would allow the optical axis of the lens film to be aligned with the multiple irregularly shaped lenses. After alignment and calibration, one lens film could be applied to multiple lenses at the same time, ensuring both application accuracy and efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide an array-type automatic alignment lens film application device that overcomes the above-mentioned defects, realizes the automatic alignment of the optical axis of the lens film at a predetermined angle of multiple lenses, and automatically completes the application of the lens film to multiple lenses.

[0007] To achieve the above objectives, the solution of the present invention is: an array-type automatic alignment and bonding lens device, comprising a frame, a lens carrier, a lens film loading carrier, and a lens film alignment and bonding carrier, wherein the lens carrier and the lens film loading carrier are respectively horizontally slidably disposed on the frame, and the lens film alignment and bonding carrier is located above the sliding path of the lens carrier and the lens film loading carrier;

[0008] The lens carrier includes a lens carrier body, on which multiple independently movable lens adjustment mechanisms are arrayed. Each lens adjustment mechanism includes a horizontal rotation drive mechanism, a lifting mechanism, and a lens carrier plate for placing lenses. The horizontal rotation drive mechanism is connected between the lens carrier body and the lifting mechanism to drive the lifting mechanism to rotate horizontally. The lifting mechanism is arranged vertically, and the top of the lifting mechanism is horizontally fixed to the lens carrier plate to drive the lens carrier plate to rise and fall, and to make the lens carrier plate rotate horizontally with the lifting mechanism. Thus, the multiple lens adjustment mechanisms make the rotation angle and height of multiple lenses consistent.

[0009] The top of the lens film loading carrier is provided with a loading plate for placing the lens film;

[0010] The lens film alignment and bonding carrier includes a support frame, a crossbeam, a lifting drive mechanism, and a carrier assembly. The support frame is longitudinally fixed above the machine frame, and the crossbeam is longitudinally slidably connected to the support frame. The lifting drive mechanism drives the crossbeam to rise and fall. The carrier assembly is mounted on the crossbeam and includes a carrier body and an XXY alignment platform. The carrier body is located below the crossbeam, and a bearing surface is formed on the bottom side of the carrier body. Multiple vacuum holes are provided on the bearing surface to adsorb the lens film on the loading plate. The XXY alignment platform drives the carrier body to move forward, backward, left, and right and rotate horizontally for alignment, thereby aligning the lens film on the carrier body with multiple lenses whose angle and height are consistent. After the carrier body descends, the lens film is bonded to each lens.

[0011] Furthermore, the lens film loading carrier is provided with a film-tearing mechanism, which includes a film-tearing gripper and a film-tearing drive mechanism. The film-tearing gripper is used to clamp the protective film attached to the lens film on the lens film alignment and bonding carrier, and the film-tearing drive mechanism drives the film-tearing gripper to move to tear off the protective film attached to the lens film.

[0012] Furthermore, the lens carrier body includes a top plate, and the lifting mechanism is a cylinder, including a lifting cylinder and a lifting piston. A shaft is fixedly attached to the bottom end of the lifting cylinder. A bearing is provided on the top plate. The lifting cylinder rotates horizontally through the shaft passing through the bearing. The shaft passes downward through the top plate. The horizontal rotation drive mechanism is located below the top plate, connected to and driving the shaft to rotate the lifting cylinder horizontally. The lifting piston extends upward from the lifting cylinder, and its top end is connected to and fixed to the lens carrier plate.

[0013] Furthermore, the lens carrier plate is equipped with a lens positioning mechanism, which includes a pneumatic push block and a positioning block. The pneumatic push block and the positioning block are respectively located on opposite horizontal sides of the lens carrier plate. The pneumatic push block is movably positioned toward the positioning block to push the lens on the lens carrier plate against the positioning block for positioning.

[0014] Furthermore, the membrane carrier body includes a membrane carrier plate, multiple pressure blocks, and a pressure block driving mechanism. The bearing surface is disposed on the bottom surface of the membrane carrier plate, and the multiple pressure blocks are respectively movably located around the perimeter of the membrane carrier plate. The pressure block driving mechanism is connected to and drives the multiple pressure blocks to press against or move away from the bearing surface.

[0015] Furthermore, the pressing block driving mechanism includes a pressing block horizontal driving mechanism and a pressing block clamping driving mechanism. The pressing block horizontal driving mechanism is connected to and drives the pressing block to extend into or retract below the bearing surface, and the pressing block clamping driving mechanism is connected to and drives the pressing block to clamp or move away from the bearing surface.

[0016] The beneficial effects of the present invention after adopting the above solution are as follows: By moving the lens film loading carrier below the lens film alignment and bonding carrier, the carrier body on the lens film alignment and bonding carrier moves downward, and the vacuum holes on the carrier body draw in air, the lens film on the lens film loading carrier can be transferred to the lens film alignment and bonding carrier. By moving the lens-carrying carrier below the lens film alignment and bonding carrier, and the carrier body of the lens film alignment and bonding carrier moves downward, one lens film can be simultaneously bonded to multiple lenses. Since each lens is placed behind its corresponding lens plate on the lens carrier, there will inevitably be a certain deviation in angle and height. By adjusting the position and posture of each lens through multiple independently moving lens adjustment mechanisms on the lens carrier, multiple lenses can be arranged in an array with the same rotation angle and height. Since the position and angle of the lens film also have a certain deviation during the loading process, the optical axis of one lens film on the film carrier body can be simultaneously aligned with the multiple lenses arranged in an array on the lens carrier by driving the carrier body to move forward, backward, left, right and horizontally through the XXY alignment platform. This makes full use of the area of ​​one lens film, enabling high-precision film application to multiple lenses at the same time, improving the efficiency of film application while ensuring the accuracy of film application.

Detailed Implementation

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This invention provides an array-type automatic lens alignment and film application device, such as... Figure 1-11 As shown, the focus here is on combining... Figure 1 As shown, the system includes a frame 1, a lens carrier 2, a lens film loading carrier 3, and a lens film alignment and bonding carrier 4. The lens carrier 2 and the lens film loading carrier 3 are horizontally slidably mounted on the frame 1. Specifically, in this embodiment, the lens carrier 2 and the lens film loading carrier 3 are connected to the frame 1 via the same linear motor 37 and slide along the same straight line under the drive of the linear motor 37. The lens film alignment and bonding carrier 4 is located above the sliding path of the lens carrier 2 and the lens film loading carrier 3. The linear motor 37 extends in a straight line to the opposite sides of the frame 1. The lens film alignment and bonding carrier 4 is located in the middle of the frame 1, meaning that the lens carrier 2 and the lens film loading carrier 3 can slide to the side of the frame 1 to facilitate the loading and unloading of lenses and lens films, and one of them can be slid under the lens film alignment and bonding carrier 4.

[0031] Key points combined Figure 3 , Figure 4 As shown, the lens carrier 2 includes a lens carrier body 47, on which multiple independently movable lens adjustment mechanisms 6 are arranged in an array. The number and array arrangement of the lens adjustment mechanisms 6 are not specifically limited. In this embodiment, a total of eight lens adjustment mechanisms 6 are provided, arranged in four rows and two columns. Each lens adjustment mechanism 6 includes a horizontal rotation drive mechanism 7, a lifting mechanism 8, and a lens carrier plate 9 for placing the lens. The horizontal rotation drive mechanism 7 can be any existing rotation drive mechanism and is not specifically limited. The horizontal rotation drive mechanism 7 is connected between the lens carrier body 47 and the lifting mechanism 8 to drive the lifting mechanism 8 to rotate horizontally. Mechanism 8 can be any existing lifting drive mechanism, without specific limitation. The lifting mechanism 8 is arranged longitudinally, and the top of the lifting mechanism 8 is horizontally fixed to the lens carrier plate 9 to drive the lens carrier plate 9 to rise and fall, and to make the lens carrier plate 9 rotate horizontally with the lifting mechanism 8. The frame 1 is also provided with a first visual sensor for detecting the position and posture of each lens on the lens carrier 2. After the lens is placed on the lens carrier plate 9, the lifting mechanism 8 of each lens adjustment mechanism 6 is controlled to adjust the height of each lens respectively, so that the top surfaces of multiple lenses are on the same plane. The rotation angle of each lens is adjusted by controlling each horizontal rotation drive mechanism 7 respectively, and the rotation angle and height of multiple lenses are adjusted to be consistent through multiple lens adjustment mechanisms 6.

[0032] Key points combined Figure 2As shown, the top of the lens film loading carrier 3 is provided with a loading plate 11 for placing the lens film 10. The upper surface of the loading plate 11 has multiple loading positioning posts 38 protruding upwards. The loading positioning posts 38 are used to abut against the edge of the lens film 10 to position the lens film 10. The lens film loading carrier 3 is provided with a film tearing mechanism 20. The film tearing mechanism 20 includes a pneumatically opening and closing film tearing claw 21 and a film tearing drive mechanism 22 for driving the film tearing claw 21 to move. The film tearing mechanism 20 can be any existing film tearing device and is not limited to being installed on the lens film loading carrier 3. It can also be installed in other positions below the lens film alignment and bonding carrier 4.

[0033] Key points combined Figure 5-11As shown, the lens film alignment and bonding carrier 4 includes a support frame 12, a crossbeam 13, a lifting drive mechanism 14, and a carrier assembly 15. The support frame 12 is longitudinally fixed above the frame 1, and the crossbeam 13 is longitudinally slidably connected to the support frame 12. In this embodiment, to improve the stability of the crossbeam 13 during lifting, two support frames 12 are spaced apart, and the crossbeam 13 is longitudinally slidably connected between the two support frames 12. The two ends of the crossbeam 13 are respectively connected to the two support frames 12 via linear guide rails. The lifting drive mechanism 14 is connected between the crossbeam 13 and the support frame 12 to drive the crossbeam 13 to lift. Specifically, in this embodiment, each support frame 12 is provided with a... Each lifting drive mechanism 14 includes a lead screw 39, a nut 40, and a lifting motor 41. The lead screw 39 extends longitudinally and is rotatably connected to the corresponding support frame 12. The nut 40 is screwed onto the lead screw 39 and fixed to the crossbeam 13. The lifting motor 41 is connected to and drives the lead screw 39 to rotate, thereby driving the nut 40 to lift the crossbeam 13. The lead screw and nut pair design allows for self-locking between the lead screw 39 and the nut 40 when the lifting motor 41 stops, preventing the crossbeam 13 from falling without drive. The carrier assembly 15 is mounted on the crossbeam 13 and includes a membrane carrier body 16 and an XXY alignment platform 17. The XY alignment platform is existing technology, and its specific structure will not be described in this embodiment. The membrane carrier body 16 is located below the crossbeam 13. A bearing surface 18 is formed on the bottom side of the membrane carrier body 16. In this embodiment, the bearing surface 18 is flat to accommodate a plane mirror. The bearing surface 18 can also be designed into other shapes to accommodate concave mirrors, convex mirrors, etc., without specific limitation. Multiple vacuum holes 19 are provided on the bearing surface 18. The multiple vacuum holes 19 are connected to a vacuum device 42 to adsorb the lens film 10 on the loading plate 11. The film-tearing claw 21 is used to clamp the protective film attached to the lens film 10 on the lens film alignment and bonding carrier 4. The film-tearing driving mechanism 22 drives the film-tearing claw 21 to move. The protective film attached to the lens film 10 is peeled off. The XXY alignment platform 17 is connected between the film carrier body 16 and the crossbeam 13 to drive the film carrier body 16 to move forward, backward, left, and right and rotate horizontally for alignment. The frame 1 is also equipped with a second visual sensor for detecting the position and posture of the lens film 10 on the lens film alignment and bonding carrier 4, thereby driving the lens film 10 on the film carrier body 16 to align with multiple lenses with the same angle and height adjustment. After the film is peeled off and the alignment is completed, the lifting drive mechanism 14 drives the crossbeam 13 to move the film carrier body 16 downward. After the film carrier body 16 moves downward, the lens film 10 is bonded to each lens, and then the multiple vacuum holes 19 on the bearing surface 18 stop sucking air.The lifting drive mechanism 14 drives the crossbeam 13 to move the film carrier body 16 upward, separating it from the lens film 10. The lens film 10 is then attached to each lens, thus automatically completing the alignment and bonding of one lens film 10 to multiple lenses.

[0034] Specifically, in this embodiment, the focus is on combining Figure 3 , Figure 4 As shown, the lens carrier body 47 includes a top plate 23, and the lifting mechanism 8 is a cylinder, including a lifting cylinder 24 and a lifting piston 25. The bottom end of the lifting cylinder 24 extends downward and is fixed with a shaft 26. A bearing 27 is provided on the top plate 23. The lifting cylinder 24 rotates horizontally through the shaft 26 passing through the bearing 27. The shaft 26 passes downward through the top plate 23. The horizontal rotation drive mechanism 7 is located below the top plate 23, connecting to and driving the shaft 26 to drive the lifting cylinder 24 to rotate horizontally. The lifting piston 25 extends upward from the lifting cylinder 24 and is fixed at its top end to the lens carrier plate 9. Thus, by using a shorter transmission chain and a simpler structure, the horizontal rotation and lifting of the lens carrier plate 9 are realized. The horizontal space occupied by a single lens adjustment mechanism 6 is smaller, allowing multiple lens adjustment mechanisms 6 to be arrayed more densely on the lens carrier body 47, making full use of the area of ​​a lens film, and enabling more lenses to be pasted on a single lens film.

[0035] Key points combined Figure 3 As shown, to prevent the lens from being placed crookedly on the lens carrier plate 9, the lens carrier plate 9 is equipped with a lens positioning mechanism 28. The lens positioning mechanism 28 includes a pneumatic push block 29 and a positioning block 30. The pneumatic push block 29 and the positioning block 30 are respectively located on opposite horizontal sides of the lens carrier plate 9. The pneumatic push block 29 is movably disposed toward the positioning block 30 to push the lens on the lens carrier plate 9 against the positioning block 30 for positioning.

[0036] Preferably, the focus is on combining Figure 5 , Figure 6 As shown, in order to avoid excessive impact on the lens when the lens film 10 carried by the film carrier body 16 comes into contact with the lens below, which would cause damage to the lens, a buffer 36 is connected between the XXY alignment platform 17 and the crossbeam 13. The XXY alignment platform 17 is longitudinally movably connected to the crossbeam 13 through the buffer 36.

[0037] Key points combined Figure 6As shown, in this embodiment, the XXY alignment platform 17 is specifically connected to the crossbeam 13 in the following manner. The XXY alignment platform 17 is located above the crossbeam 13. In this embodiment, the XXY alignment platform 17 includes a fixed plate 43, a movable plate 44, and an alignment drive mechanism 45. The fixed plate 43 is located below the movable plate 44. The fixed plate 43 is longitudinally and movably connected to the crossbeam 13 via a buffer 36. Specifically, a buffer 36 is longitudinally arranged at each of the four corners of the bottom of the fixed plate 43. The buffer 36 can be a hydraulic or spring buffer, without... The movable plate 44 is fixedly connected to the membrane carrier body 16. Specifically, each of the four corners of the movable plate 44 has a connecting rod 46 extending downwards. The crossbeam 13 avoids the connecting rods 46. The connecting rods 46 pass downwards through the crossbeam 13 and connect to the membrane carrier body 16. The alignment drive mechanism 45 is connected between the fixed plate 43 and the movable plate 44 to drive the movable plate 44 to move backwards, left and right relative to the fixed plate 43 and to rotate horizontally. In turn, the movable plate 44 drives the membrane carrier body 16 to move backwards, left and right and to rotate horizontally through the connecting rods 46. By setting the XXY alignment platform 17 above the crossbeam 13, the alignment drive mechanism 45 is pressed between the fixed plate 43 and the movable plate 44. Compared with setting the XXY alignment platform 17 below the crossbeam 13, the alignment drive mechanism 45 can withstand a greater load when under tension, resulting in better safety and stability.

[0038] Key points combined Figure 9-11 As shown, the membrane carrier body 16 includes a membrane carrier plate 31, multiple pressing blocks 32, and a pressing block driving mechanism 33. The bearing surface 18 is disposed on the bottom surface of the membrane carrier plate 31. The multiple pressing blocks 32 are respectively movably located around the perimeter of the membrane carrier plate 31. The pressing block driving mechanism 33 connects to and drives the multiple pressing blocks 32 to press against or move away from the bearing surface 18. Since the lens film 10 needs to have its protective film removed from its lower surface after being adsorbed onto the bearing surface 18 to expose the adhesive lower surface of the lens film 10, the pressing blocks 32 press the lens film 10 with the protective film onto the bearing surface 18. During the process, the fixation of the lens film 10 is enhanced; in order to ensure that the pressure block 32 can avoid the lens film 10 during the transfer of the lens film 10 to the bearing surface 18, the pressure block driving mechanism 33 includes a pressure block horizontal driving mechanism 34 and a pressure block pressing driving mechanism 35. The pressure block horizontal driving mechanism 34 is connected to and drives the pressure block 32 to extend into or retract below the bearing surface 18, and the pressure block pressing driving mechanism 35 is connected to and drives the pressure block 32 to press against or move away from the bearing surface 18. When the film tearing claw 21 retracts below the bearing surface 18, the lens film 10 can avoid being positioned above or below the bearing surface 18.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. All equivalent changes made based on the key design features of this case shall fall within the protection scope of this case.
