Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0035] Please see Figure 1 and Figure 2 The present invention provides a lens feeding mechanism, including a base plate 1, on which a lens feeding bin assembly 2, a lens transfer assembly 3, an X-axis handling robot 4 and a bonding mold 5 are provided. The lens feeding bin assembly 2 is implemented using existing technology, and the X-axis handling robot 4 is an existing dual-movement X-axis handling robot 4. The specific structures of the two are not described in detail here.

[0036] Please see Figure 3The lens transfer assembly 3 includes a Y-axis adjustment linear module 31 mounted on the equipment base plate 1. A flip motor 32 is mounted on the drive slider of the Y-axis adjustment linear module 31. The output shaft of the flip motor 32 is connected to a transfer support frame 33. A rotary motor 34 is mounted on the transfer support frame 33. The output shaft of the rotary motor 34 is coaxially connected to a transfer support seat 35. A polyhedral transfer fixture 36 is adsorbed and fixed on the transfer support seat 35. The polyhedral transfer fixture 36 flips and rotates under the coordinated drive of the flip motor 32 and the rotary motor 34, so that each face of the polyhedral transfer fixture 36 faces upwards sequentially, receiving lenses picked up from the lens feeding bin assembly 2 by the first moving part 41 of the X-axis handling robot 4.

[0037] For further details, please refer to Figure 1 In this embodiment, a positioning camera 11 is provided on the base plate 1 of the device. The positioning camera 11 is located below the movement trajectory of the first mover 41. Before the first mover 41 hands over the lens to the polyhedral transfer fixture 36, the positioning camera 11 first obtains the position information of the lens relative to the first mover 41. The first mover 41 and the Y-axis adjustment linear module 31 then adjust the position of the lens relative to the polyhedral transfer fixture 36 according to the obtained position information, so as to achieve the precise handover of the lens to the polyhedral transfer fixture 36.

[0038] For further details, please refer to Figure 1 In this embodiment, a first plasma flame nozzle 12 is also provided on the base plate 1 of the device, and the first plasma flame nozzle 12 is located below the movement trajectory of the first mover 41. After the first mover 41 picks up the lens from the lens feeding bin assembly 2, it first moves the lens directly above the first plasma flame nozzle 12. The first plasma flame nozzle 12 processes the bonding surface of the lens (that is, the lower surface of the lens) to remove oil stains from the bonding surface and improve the wettability and bonding ability of the bonding surface. The first mover 41 then moves the processed lens directly above the positioning camera 11, obtains the position information of the lens relative to the first mover 41, and then transfers the lens to each surface of the polyhedral transfer fixture 36.

[0039] In this embodiment, the transfer support frame 33 has an L-shaped frame structure, which is simple and will not interfere with the movement trajectory of the first moving part 41.

[0040] For details, please refer to Figure 4 In this embodiment, the polyhedral transfer fixture 36 adopts a polyhedral transfer suction block that can adsorb and fix the lens, and each side of the polyhedral transfer suction block is an adsorption surface 361 for adsorbing the lens.

[0041] It should be noted that in other embodiments of the present invention, the polyhedral transfer fixture 36 may also be fixed to the transfer carrier 35 by means of detachable connection such as snap-fit ​​or magnetic attraction; the lens may also be fixed to each surface of the polyhedral transfer fixture 36 by means of snap-fit.

[0042] Please see Figure 5 The bonding mold 5 includes a support spindle 51 set on the equipment base plate 1. The support spindle 51 can carry the polyhedral transfer fixture 36. Lens bonding components 52 corresponding to each face of the polyhedral transfer fixture 36 are provided on the periphery of the support spindle 51.

[0043] After the lenses are fixed on each face of the polyhedral transfer fixture 36, the second mover 42 of the X-axis transport robot 4 transfers the polyhedral transfer fixture 36 with the lenses fixed on it to the support spindle 51. The support spindle 51 can adjust the height and angle of the polyhedral transfer fixture 36 so that each face of the polyhedral transfer fixture 36 is aligned with each lens bonding assembly 52. ​​The lens bonding assembly 52 then picks up the lenses on the polyhedral transfer fixture 36 to complete the loading of the lenses onto each lens bonding assembly 52.

[0044] For details, please refer to Figure 6 In this embodiment, the supporting spindle 51 includes a support base 511 fixed on the equipment base plate 1. A lifting cylinder 512 is provided inside the support base 511, and a rotary cylinder 513 is provided at the piston end of the lifting cylinder 512. The output shaft of the rotary cylinder 513 is coaxially connected to the supporting shaft 514. The second mover 42 transfers the polyhedral transfer fixture 36, on which the lens is fixed, to the supporting shaft 514. The supporting shaft 514 and the polyhedral transfer fixture 36 are fixed with an interference fit, and can be lifted and rotated under the driving action of the lifting cylinder 512 and the rotary cylinder 513 to adjust the height and angle position of the polyhedral transfer fixture 36 in space.

[0045] It should be noted that, in this embodiment, the contact area of ​​the interference fit between the support shaft 514 and the polyhedral transfer fixture 36 should be sufficient to ensure that the polyhedral transfer fixture 36 can be easily removed from the support shaft 514; that is, the contact area of ​​the interference fit should not be too large. Of course, in other embodiments of the present invention, the support shaft 514 and the polyhedral transfer fixture 36 can also be fixed by adsorption, magnetic attraction, or other methods as described in the prior art, as long as it can ensure that the polyhedral transfer fixture 36 can be stably fixed on the support shaft 514.

[0046] For details, please refer to Figure 7In this embodiment, the lens bonding assembly 52 further includes a bonding linear module 521. The driving slider of the bonding linear module 521 is provided with a deflection angle adjuster 522. The adjustment block of the deflection angle adjuster 522 is provided with a pitch angle adjuster 523. The adjustment block of the pitch angle adjuster 523 is floatingly provided with a lens fixing block 524. The lens fixing block 524 is an adsorption block, and the lens is adsorbed and fixed on the lens fixing block 524. The bonding linear module 521 can drive the lens fixing block 524 to approach or move away from the polyhedral transfer fixture 36 on the support shaft 514, so as to realize the transfer of the lenses on each face of the polyhedral transfer fixture 36 to each lens bonding assembly 52.

[0047] It should be noted that in other embodiments of the present invention, the lens may also be snapped and fixed on the lens fixing block 524.

[0048] Please see Figure 1 and Figure 2 The present invention also provides a multi-faceted rotating mirror bonding device, including the above-mentioned lens feeding mechanism, and further including a frame feeding bin assembly 6, a frame transfer assembly 7, a frame dispensing assembly 8, and a frame pressing assembly 9. The frame feeding bin assembly 6 is implemented using existing technology, and its specific structure will not be described in detail here.

[0049] The second actuator 42 of the X-axis handling robot 4 can also transfer eyeglass frames between the eyeglass frame feeding bin assembly 6, the eyeglass frame transfer assembly 7, and the support spindle 51 of the fitting mold 5.

[0050] In this embodiment, the structure of the frame transfer assembly 7 is the same as that of the lens transfer assembly 3. The second mover 42 picks up the frame from the frame supply bin assembly 6 and places it on the transfer support 35 of the frame transfer assembly 7. The frame is then held in place by the transfer support 35. The frame is then moved below the frame dispensing assembly 8 by the Y-axis adjustment linear module 31. Under the coordinated drive of the flip motor 32 and the rotary motor 34, the frame is flipped and rotated so that the bonding surface of the frame is aligned with the dispensing needle 81 on the frame dispensing assembly 8. The dispensing needle 81 can then dispense adhesive onto the bonding surface of the frame.

[0051] In this embodiment, by making the frame transfer component 7 and the lens transfer component 3 the same design, the standardization of the component structure is achieved, which can reduce the mold opening cost in the manufacturing process of equipment components.

[0052] In this embodiment, a gantry 13 is provided on the equipment base plate 1, an X-axis handling robot 4 is provided on the first side of the gantry 13, and a lens frame dispensing assembly 8 is provided on the second side of the gantry 13.

[0053] Please see Figure 8The eyeglass frame dispensing assembly 8 includes a dispensing X-axis linear module 82, a dispensing Z-axis linear module 83 is provided on the drive slider of the dispensing X-axis linear module 82, and a dispensing positioning camera 84 and a dispensing needle 81 are provided on the drive slider of the dispensing Z-axis linear module 83.

[0054] After the frame moves below the frame dispensing assembly 8 and flips and rotates until the first bonding surface of the frame faces upwards, the dispensing positioning camera 84 first acquires the position information of that bonding surface on the frame. Then, based on the position information, the dispensing needle 81, driven by the dispensing X-axis linear module 82 and the dispensing Z-axis linear module 83, dispenses adhesive onto the bonding surface of the frame. Once the first bonding surface of the frame is dispensed, the rotary motor 34 drives the frame to rotate until the second bonding surface is directly opposite the dispensing needle 81. This process is repeated until all bonding surfaces of the frame are dispensed.

[0055] For preferred options, please refer to [link / reference]. Figure 8 In this embodiment, the drive slider of the Z-axis linear dispensing module 83 is also equipped with a second plasma flame nozzle 85 for treating the bonding surface of the eyeglass frame. Before dispensing the adhesive, the bonding surface of the eyeglass frame is first cleaned by plasma flame to remove oil and dirt from the bonding surface and improve the wettability of the bonding surface, thereby improving the bonding force between the adhesive and the bonding surface.

[0056] It should be noted that, in other embodiments of the present invention, the dispensing positioning camera 84, the dispensing needle 81 and the second plasma flame nozzle 85 can also be driven by a separate dispensing Z-axis linear module 83 to achieve independent lifting and lowering actions.

[0057] After the glue is applied, the frame is moved to the first side of the gantry frame 13 by the Y-axis adjustment linear module 31, and then transferred to the support shaft 514 of the bonding mold 5 by the second mover 42 of the X-axis transport robot 4. The frame is then aligned and pressed by the frame pressing assembly 9.

[0058] Please see Figure 9 In this embodiment, the frame pressing assembly 9 includes a Y-axis pressing linear module 91. A vertical plate 92 is mounted on the drive slider of the Y-axis pressing linear module 91. A Z-axis pressing linear module 93 is mounted on the vertical plate 92. A straightening cylinder 94 and a pressing block 95 are mounted on the drive slider of the Z-axis pressing linear module 93. The pressing block 95 is located between the two straightening jaws 941 of the straightening cylinder 94. Under the coordinated action of the straightening cylinder 94 and the Z-axis pressing linear module 93, the two straightening jaws 941 on the straightening cylinder 94 straighten the frame on the support shaft 514, and the pressing block 95 presses the frame on the support shaft 514 firmly.

[0059] Similarly, the support shaft 514 is also fixed to the frame with an interference fit, and can be raised and lowered and rotated under the drive of the lifting cylinder 512 and the rotating cylinder 513 to adjust the height and angle position of the frame in space.

[0060] The contact area of ​​the interference fit between the support shaft 514 and the frame should also ensure that the frame can be easily removed and placed off the support shaft 514; that is, the contact area of ​​the interference fit should not be too large. Of course, in other embodiments of the present invention, the support shaft 514 and the frame can also be fixed by adsorption or other methods as in the prior art, as long as the frame can be stably fixed on the support shaft 514.

[0061] After the frame is aligned and pressed on the support shaft 514, each lens bonding assembly 52 simultaneously bonds the lenses to the respective bonding surfaces of the frame. During the bonding process, the lenses on the lens fixing block 524 can have their position adjusted by the deflection angle adjuster 522 and the pitch angle adjuster 523 to ensure that the bonding accuracy meets the requirements.

[0062] The lens position is adjusted by the tilt angle adjuster 522 and the pitch angle adjuster 523. It can also be used to perform lens bonding operations on rotating mirror products with different lens tilt angles, making the equipment more widely applicable.

[0063] In this embodiment, UV adhesive is used as the bonding agent. This type of adhesive is a non-Newtonian fluid. When the lens is driven by the linear module to come into contact with the adhesive, the impact force is relatively large, and the UV adhesive will become very hard, thereby preventing the lens from moving further. However, in this embodiment, by setting the lens fixing block 524 to float, the impact force on the lens can be buffered, thereby ensuring the bonding accuracy.

[0064] Of course, in other embodiments of the present invention, other existing adhesives may be used instead of UV adhesives.

[0065] Please see Figure 7 In this embodiment, in order to further improve the efficiency of adhesive curing after bonding, a curing lamp 525 facing the lens is also provided on the lens fixing block 524.

[0066] For further details, please refer to Figure 1 The equipment also includes a finished product inspection component 100. The X-axis handling robot 4 can transfer the finished rotating mirror that has been attached to the support shaft 514 to the finished product inspection component 100 for inspection, and then transfer the inspected finished rotating mirror to the mirror frame feeding bin component 6 for storage.

[0067] For details, please refer to Figures 10-12In this embodiment, the finished product inspection component 100 includes a finished product carrier 110 and a collimator 120. The finished product carrier 110 is located on the movement trajectory of the second mover 42, and the collimator 120 is located on one side of the finished product carrier 110. After the bonding mold 5 completes the bonding of all lenses, the frame pressing component 9 is reset, and the second mover 42 transfers the finished mirror with bonded lenses to the finished product carrier 110. The finished product carrier 110 can drive the finished product to rotate, and the collimator 120 is used to detect the bonding flatness of each bonded lens.

[0068] In this embodiment, the structure of the finished product carrier 110 is the same as that of the supporting spindle 51, and its specific structure will not be described in detail here.

[0069] In this embodiment, a protective cover 130 is provided on the base plate 1 of the equipment, and a collimator 120 is disposed inside the protective cover 130. The protective cover 130 has an opening on the side near the finished product carrier 110. A through groove 131 is provided on the first side plate of the protective cover 130, and a slide rail 132 is provided on the outer wall of the first side plate of the protective cover 130. A connecting block 133 is slidably disposed on the slide rail 132, and the connecting block 133 passes through the through groove 131 and connects to the collimator 120. A roller 134 is provided on the connecting block 133, and a detection Z-axis linear module 140 is provided on the outer wall of the first side plate of the protective cover 130. The drive slider of the detection Z-axis linear module 140 abuts against the roller 134, so that the connecting block 133 can be driven by the detection Z-axis linear module 140 to drive the collimator 120 to move along the slide rail 132, thereby enabling the collimator 120 to adjust the angle of the detection light to detect rotating mirror products with different lens tilt angles, and to simulate the actual working conditions of rotating mirrors for detection, thereby improving the detection accuracy.

[0070] Furthermore, to ensure the reliability of the contact between the drive slider of the detection Z-axis linear module 140 and the roller 134, the connecting block 133 and the drive slider of the detection Z-axis linear module 140 are also connected by a tension spring 150.

[0071] It should be noted that the various linear modules used in the embodiments of the present invention can be selected from existing linear motor modules, linear cylinder modules, linear synchronous belt modules or other modules capable of linear motion, as needed.

[0072] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions and substitutions can be made without departing from the inventive concept, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
