Description

Technical Field

[0001] This utility model relates to the technical field of optical lens manufacturing, and specifically to a device for attaching filters to lenses. Background Technology

[0002] Camera sensors can detect not only visible light but also near-infrared light with longer wavelengths. During the day, sunlight contains a large amount of infrared radiation. Camera sensors receive both visible and infrared light simultaneously. Infrared radiation can "pollute" the visible light signal, causing color distortion in the images captured by the camera. To solve this problem and make the images captured by the camera closer to the colors seen by the human eye, designers typically attach filters to the camera lens. These filters block or reflect most infrared light but allow visible light to pass through, thus reducing infrared interference.

[0003] Most existing equipment for attaching filters to lenses directly applies adhesive to the lens's adhesive surface and then attaches the filter to the adhesive surface to complete the filter attachment. However, the quality of the filter attachment is not high. Utility Model Content

[0035] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0036] Please see Figure 1 The present invention provides a device for attaching filters to lenses, comprising a base plate 1, on which a turntable mechanism 2, a lens feeding and finished product unloading mechanism 3, a plasma cleaning mechanism 4, a lens dispensing and filter feeding mechanism 5, and a curing mechanism 6 are provided.

[0037] Please see Figure 2 The turntable mechanism 2 includes a rotary motor 21 mounted on the equipment base plate 1. A mounting plate 22 is coaxially fixed to the output shaft of the rotary motor 21. A first lifting cylinder 23 is coaxially fixed to the mounting plate 22. A rotating disk 24 is coaxially fixed to the piston rod of the first lifting cylinder 23. Four transport grippers 25 are fixed on the rotating disk 24, and the four transport grippers 25 are arranged at equal intervals along the circumference of the rotating disk 24. The rotary motor 21 drives the rotating disk 24 to rotate 90 degrees clockwise each time. After each 90-degree rotation, the first lifting cylinder 23 drives the rotating disk 24 to rise and fall, enabling the transport grippers 25 to sequentially transport the lenses to the lens feeding and finished product unloading mechanism 3, the plasma cleaning mechanism 4, the lens dispensing and filter feeding mechanism 5, and the curing mechanism 6. The finished products on the curing mechanism 6 are then transported to the lens feeding and finished product unloading mechanism 3 for collection.

[0038] Please see Figure 1 and Figure 3 The lens feeding and finished product unloading mechanism 3 includes a hopper assembly 31, a first Y-axis transport assembly 32, a first X-axis transport assembly 33, and a first transition carrier 34, which are sequentially connected on the equipment base plate 1. The hopper assembly 31 is used to hold multiple first trays 35, and the first trays 35 are used to hold multiple lenses or finished products. The first Y-axis transport assembly 32 is used to pick up and put the first trays 35 from the hopper assembly 31 and transfer the first trays 35 to below the first X-axis transport assembly 33. The first X-axis transport assembly 33 is used to transfer lenses or finished products between the first trays 35 on the first Y-axis transport assembly 32 and the first transition carrier 34. The first transition carrier 34 is connected to the transport gripper 25 on the turntable mechanism 2 at a first position.

[0039] Please see Figure 4 and Figure 5 The hopper assembly 31 includes a square tube hopper body 311 and an electric screw 313. The electric screw 313 drives the square tube hopper body 311 to move up and down, and the square tube hopper body 311 and the electric screw 313 are detachably connected.

[0040] Specifically, a hanging plate 11 is fixed to the bottom of the equipment base plate 1. The screw sleeve 3131 of the electric screw 313 is fixed to the hanging plate 11. Four optical shafts 314 are slidably arranged on the hanging plate 11. The top of the optical shafts 314 is connected to a positioning plate 316, and the bottom of the optical shafts 314 is fixed to a connecting plate 315. The top end of the electric screw 313 is rotatably connected to the positioning plate 316, and the bottom end of the electric screw 313 is rotatably connected to the connecting plate 315. Thus, when the electric screw 313 is working, under the cooperation of the electric screw 313 and the screw sleeve 3131, the positioning plate 316, the optical shafts 314, the connecting plate 315, and the electric screw 313 together move up and down relative to the hanging plate 11. The top of the positioning plate 316 is provided with a positioning protrusion 3161 and two anti-rotation blocks 3162. The bottom of the square tube hopper 311 is provided with positioning holes that mate with the positioning protrusion 3161, and the anti-rotation blocks mate with the two ends of one side of the square tube hopper 311. When the electric screw 313 drives the positioning plate 316 to move up and down together, it can also drive the square tube hopper 311 to move up and down together. When it is necessary to replace the first tray 35 of the square tube hopper 311, the entire square tube hopper 311 containing multiple layers of the first tray 35 can be removed and replaced, instead of replacing them one by one on the machine, which is very convenient to use.

[0041] The inner walls of both sides of the square tube hopper 311 are provided with corresponding multi-layer partitions 3111, and the first material tray 35 is placed on a pair of partitions 3111. Both open sides of the square tube hopper 311 are provided with a stop bar 3112, which is used to restrict the first material tray 35 inside the square tube hopper 311 to prevent the first material tray 35 from sliding out of the square tube hopper 311 when the square tube hopper 311 is replaced. Both ends of the stop lever 3112 are rotatably connected to the square tube hopper 311 via a swing arm 3113. The swing arm 3113 connected to the top of the stop lever 3112 is also fitted with a compression spring 3114. The bottom end of the square tube hopper 311 is provided with a locking notch. Under the elastic force of the compression spring, the swing arm 3113 connected to the bottom end of the stop lever 3112 can be locked into the locking notch to lock the stop lever and prevent the stop lever 3112 from automatically opening when the square tube hopper 311 is replaced, which would cause the first material tray 35 to slide out of the square tube hopper 311.

[0042] The side wall of the square tube hopper 311 is also provided with a receiving groove 3115. In the working state, the stop lever 3112 near the first Y-axis conveying assembly 32 is pressed down to unlock and swung into the receiving groove 3115, thereby opening the stop lever 3112, which facilitates the first Y-axis conveying assembly 32 to pick up and put down the first material tray 35 in the square tube hopper 311. The top of the square tube hopper 311 is also provided with a handle 3116, which is convenient for removing the square tube hopper 311 when changing it.

[0043] A square tube protective cover 327 is also provided on the base plate 1 of the equipment. The square tube hopper 311 is located inside the square tube protective cover 327. A through-beam fiber optic sensor 328 and a reflective fiber optic sensor 329 are provided on the square tube protective cover 327. The transmitter and receiver of the through-beam fiber optic sensor 328 are located on both sides of the square tube hopper 311, and the two side walls of the square tube hopper 311 are provided with clearance holes 3117 for light signals to pass through. Thus, the position of the first material tray 35 inside the square tube hopper 311 can be detected by the through-beam fiber optic sensor 328, thereby facilitating the control of the electric screw 313 to drive the square tube hopper 311 to lift and lower. The reflective fiber optic sensor 329 is positioned toward the receiving groove 3115 to detect whether there is a stop bar 3112 in the receiving groove 3115, thereby determining whether the stop bar 3112 is in the open state. Only when the stop bar 3112 near the first Y-axis conveying assembly 32 is in the open state can the first Y-axis conveying assembly 32 pick up and put the first material tray 35 in the square tube hopper 311.

[0044] It should be understood that the first tray 35 has sufficient weight so that even when the lever 3112 near the first Y-axis conveying assembly 32 is in the open state during operation, the first tray 35 will not automatically slide out of the square tube compartment 311. The contact surface between the first tray 35 and the spacer 3111 can also be designed with a certain anti-slip capability, such as having a rubber layer on the contact surface.

[0045] Please see Figure 6 and Figure 7 The first Y-axis conveying assembly 32 further includes a first Y-axis linear module 321. A tray fixing plate 322 for picking up and placing the first tray 35 is connected to the drive block of the first Y-axis linear module 321. The tray fixing plate 322 is provided with a limit stop 323 and a pressing cylinder 324. A push block 325 is provided on the piston rod of the pressing cylinder 324. When the first tray 35 is picked up from the square tube hopper 311, the first Y-axis linear module 321 drives the tray fixing plate 322 to extend below the first tray 35 inside the square tube hopper 311. The electric screw 313 then drives the square tube hopper 311 to descend, causing the first tray 35 to fall between the push block 325 and the limit stop 323. The pressing cylinder 324 then drives the push block 325 to move towards the limit stop 323, thus clamping and fixing the first tray 35. Finally, the first Y-axis linear module 321 drives the tray fixing plate 322 to exit the square tube hopper 311. Limiting pressure strips 326 are also provided on both sides of the first Y-axis linear module 321, which abut against the two sides of the first tray 35 respectively, to prevent the first tray 35 from shifting during the removal process.

[0046] Please see Figure 8 The first X-axis conveying assembly 33 includes a first X-axis linear module 331 mounted on the equipment base plate 1. The first X-axis linear module 331 is located above and orthogonally arranged to the first Y-axis linear module 321. A first Z-axis linear module and a second Z-axis linear module are mounted on the drive plate of the first X-axis linear module 331. The drive end of the first Z-axis linear module is equipped with a lens cylinder gripper 332, and the drive end of the second Z-axis linear module is equipped with a finished product cylinder gripper 333. After the first Y-axis linear module 321 removes the first tray 35 containing lenses from the square tube hopper 311, it drives the first tray 35 to move below the first X-axis linear module 331. The lens cylinder gripper 332 picks up the lenses from the first tray 35 and places them onto the first transition carrier 34, thus loading the lenses. The finished product cylinder gripper 333 picks up the finished products from the first transition carrier 34 and places them into the first tray 35, thus collecting the finished products.

[0047] The drive board of the first X-axis linear module 331 is also equipped with a first detection camera 334 and a laser coaxial displacement meter 335. Before the lens cylinder gripper 332 picks up the lens, the first detection camera 334 first obtains the coordinate position of the lens in the first material tray 35 and detects the appearance of the lens. Before the finished product cylinder gripper 333 picks up the finished product, the laser coaxial displacement meter 335 first detects the parallelism between the filter and the lens in the finished product. The specific detection principle is existing technology and will not be described in detail here. The material tray fixing plate 322 is also equipped with an NG tray 327, and an NG material tray 328 is fixed on the NG tray 327. The NG material tray 328 is used to collect the defective products detected by the first detection camera 334 and the laser coaxial displacement meter 335.

[0048] Please see Figure 3 The equipment base plate 1 is also equipped with a first angle adjustment motor 12. The first transition carrier 34 is coaxially set on the output shaft of the first angle adjustment motor 12. Before the finished product cylinder gripper 333 picks up the finished product, the angle of the finished product on the first transition carrier 34 is obtained by the first detection camera 334, and the finished product is adjusted to the preset angle position by the first angle adjustment motor 12, which makes it more convenient for the finished product cylinder gripper 333 to pick up the finished product.

[0049] Please see Figure 9 The plasma cleaning mechanism 4 includes a plasma nozzle assembly 41 and a second Y-axis transport assembly 42 mounted on the equipment base plate 1. The second Y-axis transport assembly 42 is used to receive the lens transported by the transport gripper 25 and transport the lens to the bottom of the plasma nozzle assembly 41. The plasma nozzle assembly 41 is used to perform plasma cleaning on the adhesive surface of the lens on the second Y-axis transport assembly 42.

[0050] The plasma nozzle assembly 41 includes a mounting bracket 411 mounted on the equipment base plate 1 and a plasma nozzle 412 mounted on the mounting bracket 411. The second Y-axis transport assembly 42 includes a second Y-axis linear module 421 mounted on the equipment base plate 1. A support plate 422 is connected to the drive block of the second Y-axis linear module 421, and a transport carrier 423 for receiving lenses is mounted on the support plate 422. The transport grippers 25 on the turntable mechanism 2 transport the lens from the first transition carrier 34 to the transport carrier 423. The second Y-axis linear module 421 then drives the transport carrier 423 to move below the plasma nozzle 412, activating the plasma nozzle 412 to perform plasma cleaning on the adhesive-coated surface of the lens on the transport carrier 423. The plasma nozzle assembly 41 adopts an offline design that removes the lens from the turntable mechanism 2 for cleaning, reducing the impact of plasma cleaning on the transport grippers 25 and other structures on the turntable mechanism 2, and ensuring the stability of the plasma cleaning process.

[0051] To ensure the safety of the plasma cleaning process, the plasma nozzle assembly 41 also includes a safety guard 413 fixed on the equipment base plate 1. The working end of the plasma nozzle 412 is placed inside the safety guard 413, and the transport carrier 423 can move into the safety guard 413 under the driving action of the second Y-axis linear module 421.

[0052] To facilitate the traceability of operational information, a barcode scanner 13 is installed on the base plate 1 of the equipment, and a barcode scanning motor 4221 that drives the transport carrier 423 to rotate is installed on the support plate 422. The safety guard 413 is provided with a barcode scanning window 4131 facing the barcode scanner 13. After the second Y-axis linear module 421 drives the transport carrier 423 to move to the bottom of the plasma nozzle 412, the barcode scanning motor 4221 first drives the transport carrier 423 to rotate, thereby rotating the lens. At the same time, the barcode scanner 13 identifies the QR code label on the rotating lens through the barcode scanning window 4131, thereby binding the operational information with the QR code.

[0053] Please see Figure 10 The lens dispensing and filter feeding mechanism 5 includes a third Y-axis transport assembly 51, a second X-axis transport assembly 52, and a second transition carrier 53, which are sequentially connected. The third Y-axis transport assembly 51 is mounted on the equipment base plate 1 and is used to place a second tray (not shown in the figure) and transport the second tray to below the second X-axis transport assembly 52. ​​The second tray is used to hold multiple filters. The second X-axis transport assembly 52 is used to transport the filters between the third Y-axis transport assembly 51 and the second transition carrier 53, and to dispense adhesive onto the lens on the second transition carrier 53 after plasma cleaning.

[0054] Please see Figure 11 The third Y-axis conveying assembly 51 further includes a third Y-axis linear module 511 mounted on the equipment base plate 1. An adsorption plate 512 is connected to the drive block of the third Y-axis linear module 511. A second material tray is placed on the adsorption plate 512. The second material tray has multiple adsorption holes communicating with the air suction channel of the adsorption plate 512. A filter is placed on the adsorption holes, so that the filter is fixed within the second material tray under negative pressure and will not shift. Two sets of the third Y-axis conveying assembly 51 are provided to achieve alternating material feeding and improve material changing efficiency.

[0055] Please see Figure 12 The second X-axis transport assembly 52 further includes a second X-axis linear module 521 and a fourth Y-axis linear module 522. The second X-axis linear module 521 is mounted on the drive block of the fourth Y-axis linear module 522. The drive plate of the second X-axis linear module 521 is provided with a third Z-axis linear module and a fourth Z-axis linear module. The drive end of the third Z-axis linear module is provided with a dispensing needle 523, and the drive end of the fourth Z-axis linear module is provided with a transport suction pen 524.

[0056] The transport gripper 25 on the turntable mechanism 2 transports the plasma-cleaned lens to the second transition carrier 53. The dispensing needle 523, in coordination with the second X-axis linear module 521, the fourth Y-axis linear module 522 and the third Z-axis linear module, dispenses adhesive onto the dispensing surface of the lens.

[0057] The drive board of the second X-axis linear module 521 is also equipped with a filter pickup and positioning camera 525. Before the transport pen 524 picks up the filter, the filter pickup and positioning camera 525 first obtains the position of the filter in the second tray so that the transport pen 524 can accurately pick up the filter.

[0058] A filter bonding and positioning camera 526 is also provided on the base plate 1 of the equipment. The filter bonding and positioning camera 526 is located below the transport trajectory of the transport pen 524. The transport pen 524 first transports the filter to the top of the filter bonding and positioning camera 526 to obtain the position of the filter relative to the transport pen 524. Then, the position of the filter is adjusted by the second X-axis linear module 521 and the fourth Y-axis linear module 522 to ensure that the filter is accurately bonded to the adhesive surface of the lens.

[0059] The second X-axis transport assembly 52 also includes a gantry bracket 527, and a Y-axis guide rail 528 is provided on the equipment base plate 1. A slider is provided on the Y-axis guide rail 528. The gantry bracket 527 is connected to the drive block and slider of the fourth Y-axis linear module 522 to ensure the stability of the second X-axis transport assembly 52 moving along the Y-axis direction.

[0060] Please see Figure 10 The equipment base plate 1 is also equipped with a second angle adjustment motor 14. The second transition carrier 53 is coaxially mounted on the output shaft of the second angle adjustment motor 14. The second angle adjustment motor 14 adjusts the angle position of the lens according to the position of the obtained filter relative to the transport pen 524 to ensure that the angle of the filter and the lens are consistent.

[0061] Please see Figure 13 The equipment base plate 1 is also equipped with a glue-wiping assembly 54, which is located on one side of the fourth Y-axis linear module 522. The glue-wiping assembly 54 includes a wiping cloth feed roll 541, a wiping cloth take-up roll 542, a wiping cloth clamping cylinder 543, and several rollers 544.
