[0050] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0051] Please refer to Figures 1 to 3As shown, in one aspect, this utility model embodiment provides a lens dispensing device for dispensing adhesive onto a lens. The lens dispensing device includes a dispensing module 100, a pre-curing module 200, a detection and marking module 300, a UV curing module 400, and a conveying module 500. The dispensing module 100 is adapted to dispensing adhesive at the dispensing position on the lens. The pre-curing module 200 is located downstream of the dispensing module 100 and is adapted to partially cure the adhesive on the lens. The detection and marking module 300 is located downstream of the pre-curing module 200 and includes a vision inspection module 310 and a marking mechanism 320. The UV curing module 400 is located downstream of the detection and marking module 300 and is adapted to fully cure the adhesive. The conveying module 500 is connected to the dispensing module 100, the pre-curing module 200, the detection and marking module 300, and the UV curing module 400, and is used to convey the lens.

[0052] According to the lens dispensing device of this utility model embodiment, the conveying module 500 conveys the lens to the dispensing module 100 for dispensing. The lens after dispensing is conveyed to the pre-curing module 200 to cure part of the adhesive. The lens after pre-curing is conveyed to the inspection and marking module 300. The visual inspection module 310 of the inspection and marking module 300 performs defect detection on the lens (such as dirt, missing parts, missing adhesive, etc.). The marking mechanism 320 marks and distinguishes the lenses that fail the inspection. Finally, the lens is conveyed to the UV curing module 400 to complete the complete curing of the adhesive.

[0053] According to the lens dispensing equipment of this utility model embodiment, by using the detection and marking module 300 to identify and mark lens defects during lens transportation, the lens dispensing equipment achieves automated defect detection, effectively improving production efficiency; and by setting the detection and marking module 300 between the pre-curing module 200 and the UV curing module 400, there is no need to redesign the output end of the UV curing module 400, which is conducive to reusing the existing UV curing module 400 and reducing the production and manufacturing cost of the lens dispensing equipment.

[0054] In this embodiment, the pre-curing module 200 includes a pre-curing pressure head and a pre-curing lamp assembly. The pre-curing pressure head is used to press against the components in the lens so that the distance between the components in the lens meets the design requirements, and the pre-curing lamp assembly partially cures the adhesive at the dispensing position.

[0055] In some embodiments, combined with Figure 3 and Figure 4As shown, the marking mechanism 320 includes a marking base 321, a marker pen clamp 322, an elastic buffer 323, and a clamp driving assembly 324. The marker pen clamp 322 is adapted to hold a marker pen. The marker pen clamp 322 is slidably connected to the marking base 321 along a first direction (Z direction in the figure). The marker pen clamp 322 can move under the drive of the clamp driving assembly 324. The two ends of the elastic buffer 323 are respectively connected to the marker pen clamp 322 and the clamp driving assembly 324.

[0056] In this embodiment, the movable end of the clamp driving assembly 324 moves and drives the elastic buffer 323 and the marker pen clamp 322 to move downward along the Z direction shown in the figure until the marker pen in the marker pen clamp 322 abuts against the lens surface. At this time, the movable end of the clamp driving assembly 324 continues to move downward, the elastic buffer 323 is compressed, and the elastic restoring force of the elastic buffer 323 pushes against the marker pen clamp 322, so that the marker pen in the marker pen clamp 322 presses against the lens to print a mark.

[0057] By setting an elastic buffer 323, a flexible connection is achieved between the marker pen holder 322 and the holder drive assembly 324. This avoids the marker pen from damaging the lens due to excessive driving force of the holder drive assembly 324, while ensuring full contact between the marker pen and the lens, thus improving the marking effect.

[0058] In this embodiment, the elastic buffer 323 can be a spring, or it can be a silicone pad, a spring sheet, etc.

[0059] In one embodiment, combined Figure 3 and Figure 4 As shown, the marking mechanism 320 also includes a positioning plate 325, which is connected to the marking base 321. The positioning plate 325 is positioned at a preset distance from the marking pen holder 322 along a first direction. It can be understood that since the positioning plate 325 is relatively fixed to the fixed end of the clamping drive assembly 324, by controlling the position of the marking pen holder 322 driven by the clamping drive assembly 324 at a specific state (such as the starting position of the marking pen holder 322's movement) relative to the positioning plate 325, when installing the marking pen, simply abutting the marking pen against the positioning plate 325 ensures that the position of the marking pen in the marking pen holder 322 is the same each time it is installed. This allows for direct marking without repeated calibration of the marking position, effectively improving production efficiency. The preset distance can be adjusted based on marking pens of different lengths.

[0060] In one embodiment, combined Figure 3 and Figure 4As shown, the clamp driving assembly 324 includes a clamp driving member 3241 and a buffer base 3242. The buffer base 3242 is slidably connected to the marking base 321 along a first direction. The buffer base 3242 can move under the drive of the clamp driving member 3241. The buffer base 3242 is provided with a connecting through hole, and a connecting post 3243 is inserted through the connecting through hole. The connecting post 3243 includes a rod and a cap. The first end of the rod is connected to the marking pen clamp 322, and the second end of the rod is fixed with the cap. The cap is located on the side of the connecting through hole away from the marking pen clamp 322. An elastic buffer member 323 is sleeved on the rod.

[0061] In this embodiment, the buffer base 3242 and the marker pen clamp 322 are movably connected and limited by the connecting post 3243, and the elastic buffer 323 is sleeved on the outside of the rod of the connecting post 3243, so that the elastic buffer 323 only deforms in the Z direction under the guidance of the rod, thus ensuring the buffering effect.

[0062] In this embodiment, the marker pen holder 322 and the buffer base 3242 share a common track to achieve movement along the Z direction. In other embodiments, different tracks can be set, and the tracks can also be staggered to ensure that both the buffer base 3242 and the marker pen holder 322 can move along the Z direction.

[0063] In some embodiments, combined with Figures 1 to 3 As shown, the marking mechanism 320 also includes a marking linear module 330, which spans above the conveying path of the conveying module 500. The movable end of the marking linear module 330 is connected to the marking base 321, and the vision inspection module 310 is fixed to the marking base 321.

[0064] In this embodiment, the marking line module 330 extends along the X direction as shown in the figure. The visual inspection module 310 and the marking mechanism 320 move along the X direction under the drive of the marking line module 330, so that the detection and marking module 300 is not only suitable for the detection and marking of a single lens. When the lens carrier plate on the conveying module 500 is set to convey multiple lenses at one time, the relative positions of different lenses and the marking mechanism 320 or the visual inspection module 310 are adjusted by the coordinated movement of the marking line module 330 and the conveying module 500, so that the detection and marking module 300 can detect and mark all lenses on a lens carrier plate.

[0065] In some embodiments, combined with Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the lens dispensing equipment also includes a pressure module 600 located upstream of the dispensing module 100. The pressure module 600 includes several pressure heads. The conveying module 500 includes a feeding connection conveying mechanism 510 and a dispensing conveying mechanism 520. The feeding connection conveying mechanism 510 includes a feeding carrier platform 511 and a feeding linear module 512 extending along a second direction (X direction in the figure). The pressure heads span across the feeding linear module 512. The feeding linear module 512 has several discharge positions, and the discharge positions are connected to the dispensing conveying mechanism 520.

[0066] In this embodiment, before dispensing by the dispensing module 100, the feeding linear module 512 transports the lens on the feeding carrier platform 511 to the underside of the pressing head of the pressing module 600. The pressing head presses against the component in the lens, so that the position of the component before dispensing meets the design requirements. The lens after pressing is transferred to the dispensing conveying mechanism 520 through the outlet position of the feeding linear module 512, and then conveyed by the dispensing conveying mechanism 520 to the dispensing module 100 for dispensing.

[0067] In one embodiment, combined Figure 1 and Figure 2 As shown, the conveying module 500 includes multiple dispensing conveying mechanisms 520, and the dispensing module 100 includes multiple dispensing mechanisms 110, the number of which is adapted to the number of dispensing conveying mechanisms 520.

[0068] In this embodiment, the conveying module 500 includes two dispensing conveying mechanisms 520, and the dispensing module 100 is provided with two dispensing mechanisms 110 corresponding one-to-one with the dispensing conveying mechanisms 520. Correspondingly, the feeding linear module 512 is provided with two discharge positions to connect with the dispensing conveying mechanisms 520. By setting multiple dispensing conveying mechanisms 520 and dispensing mechanisms 110, the transfer and dispensing of multiple sets of lenses can be completed simultaneously, improving production efficiency.

[0069] In other embodiments, the number of dispensing conveying mechanisms 520 and dispensing mechanisms 110 can be adjusted according to actual needs, and the number can be adapted accordingly. For example, four dispensing conveying mechanisms 520 and two dispensing mechanisms 110 can be set at the same time.

[0070] In one embodiment, combined Figure 5 and Figure 6 As shown, the dispensing conveying mechanism 520 includes a dispensing carrier platform 521 and a dispensing conveying linear module 522. The dispensing carrier platform 521 can be driven by the dispensing conveying linear module 522 to move along a third direction (Y direction in the figure), and the third direction is set at an angle to the second direction (X direction in the figure).

[0071] In this embodiment, lens transfer between the feeding carrier platform 511 and the dispensing carrier platform 521 can be achieved through a conveyor belt. Specifically, the feeding carrier platform 511 moves to the discharge position, and the output end of the conveyor belt of the feeding carrier platform 511 is connected to the input end of the conveyor belt of the dispensing carrier platform 521.

[0072] In this embodiment, the feeding carrier platform 511 and the dispensing carrier platform 521 are also equipped with lifting cylinders to lift their respective conveyor belts, so that the lens carrier plate carrying the lens comes into contact with the conveyor belt, thereby realizing the transfer of the lens carrier plate.

[0073] In some embodiments, combined with Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the conveying module 500 also includes a curing connection conveying mechanism 530 and a curing conveying mechanism 540. The curing connection conveying mechanism 530 is connected to the dispensing conveying mechanism 520 and the curing conveying mechanism 540. The curing conveying mechanism 540 is connected to the curing connection conveying mechanism 530, the pre-curing module 200, the inspection and marking module 300 and the UV curing module 400.

[0074] In this embodiment, a curing connection conveyor 530 is provided for multiple dispensing conveyors 520 to output lenses conveyed by different dispensing conveyors 520 after dispensing is completed to a single curing conveyor 540 through the discharge position of the curing connection conveyor 530. This ensures that multiple groups of lenses enter the pre-curing module 200, the inspection and marking module 300 and the UV curing module 400 in an orderly manner, thus ensuring orderly production.

[0075] In this embodiment, the curing connection and conveying mechanism 530 includes a curing connection carrier platform 531 and a curing connection linear module 532. The curing connection carrier platform 531 can move along a second direction (X direction in the figure) under the drive of the curing connection linear module 532. Since the curing connection and conveying mechanism 530 only needs to transport and transfer lenses and does not need to position lenses, therefore... Figure 7 As shown, the curing docking carrier platform 531 may include a conveyor belt for transporting the lens carrier plate.

[0076] In this embodiment, the curing conveying mechanism 540 includes a curing conveying carrier platform 541 and a curing conveying linear module 542. The curing conveying carrier platform 541 can move along a third direction (Y direction in the figure) under the drive of the curing conveying linear module 542. The specific structure is as follows: Figure 8 As shown, similar to the dispensing conveyor mechanism 520, it has a conveyor belt that connects to the curing docking carrier platform 531, and a lifting cylinder that drives the conveyor belt to lift. Its working principle is the same as that of the feeding carrier platform 511 and the dispensing carrier platform 521 mentioned above.

[0077] In some embodiments, combined with Figure 1 and Figure 2 As shown, the dispensing module 100 also includes a dispensing linear module 120, which spans above the dispensing conveying mechanism 520. The dispensing mechanism 110 can move along a second direction (X direction in the figure) under the drive of the dispensing linear module 120.

[0078] In this embodiment, the dispensing mechanism 110 moves along the X direction under the drive of the dispensing linear module 120, so that the dispensing mechanism 110 is not only suitable for dispensing a single lens. When the lens carrier plate on the conveying module 500 is set to convey multiple lenses at one time, the dispensing linear module 120 and the conveying module 500 cooperate to move and adjust the relative positions of multiple lenses and the dispensing mechanism 110, so as to realize the detection of the dispensing module 100 dispensing all lenses on a lens carrier plate.

[0079] In some embodiments, combined with Figure 1 and Figure 9 As shown, the dispensing mechanism 110 includes a dispensing head clamp 111 and a rotary drive 112. The dispensing head clamp 111 is provided with a clamping groove for clamping the dispensing head. The axis of the clamping groove is set at an angle to the axis of the rotary drive 112. The dispensing head clamp 111 can rotate around the axis of the rotary drive 112 under the drive of the rotary drive 112.

[0080] In this embodiment, the dispensing head held by the dispensing head clamp 111 is driven to rotate by the rotary drive 112, so that the dispensing head can perform circumferential dispensing around the axis of the lens. Furthermore, in conjunction with the dispensing linear module 120 (X direction) and the dispensing transport linear module 522 (Y direction) of the dispensing module 100, interpolation circular dispensing can be achieved, effectively accommodating different dispensing methods.

[0081] On the other hand, this utility model embodiment also provides a lens production line, including the lens dispensing equipment as described in the above embodiment.

[0082] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
