Description

Technical Field

[0001] This invention relates to the field of lens assembly technology, and more particularly to a lens assembly device. Background Technology

[0002] With the popularization of automated equipment and the improvement of automation technology, the use of automated equipment in the lens assembly field is becoming more and more common. Existing lens assembly equipment generally transfers directly to the back end for fixing after the components are assembled into the lens frame. However, the assembly cycle of the components is much longer than the cycle of fixing the components to the lens frame. As a result, when the front-end component assembly device is assembling the components into the lens frame, it needs to wait for the back-end fixing device to fix the previous lens semi-finished product, thus resulting in low production efficiency of lens assembly.

[0003] Based on the above situation, we urgently need to design a lens assembly device to solve the above problems. Summary of the Invention

[0004] One objective of this invention is to provide a lens assembly device in which a transfer device enables the first component assembly device to work without waiting for the fixing device to work, thus ensuring a continuous overall assembly process and improving production efficiency.

[0065] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail 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 are within the scope of protection of the present invention.

[0066] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0067] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0068] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0069] like Figure 1 and Figure 2 As shown, this embodiment provides a lens assembly device, including a frame 1, a first component assembly device 2, a fixing device 3, and a transfer device 4. The first component assembly device 2, the fixing device 3, and the transfer device 4 are all mounted on the frame 1. The fixing device 3 is located downstream of the first component assembly device 2, and the transfer device 4 is located between the two. The transfer device 4 is provided with a first transfer section 421 and a second transfer section 422. The first transfer section 421 and the second transfer section 422 are respectively alternately located at the work station of the first component assembly device 2 and the work station of the fixing device 3, and can place the first lens semi-finished product produced by the first component assembly device 2. When producing lens modules in a lens assembly device, the first component assembly device 2 first assembles the first component into a lens frame to form a first lens semi-finished product. At this time, the first transfer unit 421 is located at the work station of the first component assembly device 2 to transfer the first lens semi-finished product from the work station of the first component assembly device 2 to the work station of the fixing device 3. The fixing device 3 can fix the first component into the lens frame to form a lens module. At this time, the second transfer unit 422 is located at the work station of the first component assembly device 2. Then, the first component assembly device 2 can continue to produce the first lens semi-finished product without waiting for the work of the fixing device 3. Finally, the second transfer unit 422 transfers the next first lens semi-finished product from the work station of the first component assembly device 2 to the work station of the fixing device 3. At this time, the first transfer unit 421 returns to the work station of the first component assembly device 2. It is understandable that in the entire assembly process, the working cycle of the fixing device 3 is much longer than that of the first component assembly device 2. However, in this embodiment, due to the setting of the transfer device 4, the first component assembly device 2 does not need to wait for the fixing device 3 to complete the fixing process. The material pulling process from the first component assembly device 2 to the fixing device 3 can be completed while the fixing device 3 is working, thereby shortening the production cycle of the entire lens module and improving production efficiency.

[0070] In this embodiment, the transfer device 4 includes a first driving component 41 and a rotating frame 42. The first driving component 41 can be a motor or a rotary cylinder. In this embodiment, the first driving component 41 is a rotary cylinder, which is mounted on the frame 1. The rotating frame 42 is connected to the output end of the rotary cylinder and is Y-shaped. The first transfer part 421 and the second transfer part 422 are configured as receiving slots, which are respectively opened at both ends of the Y-shaped rotating frame 42. Specifically, when the first receiving slot contains a first lens semi-finished product, the rotary cylinder drives the rotating frame 42 to rotate to change the position of the two receiving slots, so that the first receiving slot is located at the station of the fixing device 3 for loading, and the second receiving slot is located at the station of the first component assembly device 2 for the next transfer. In other embodiments of the present invention, the first transfer part 421 and the second transfer part 422 may also be configured as grippers, and the first driving member 41 may be configured as a linkage mechanism. The linkage mechanism can link the grippers at both ends. When the gripper at the station of the first component assembly device 2 slides to the station of the fixing device 3, the gripper at the station of the fixing device 3 slides to the station of the first component assembly device 2. For example, the linkage mechanism may be a gear that is connected to a rack on both sides of the gear, and grippers are respectively provided on the two racks. Alternatively, it may be a screw that is connected to two screws in opposite directions, and nuts and grippers on the nuts are respectively provided on the two screws. Both can achieve synchronous loading and unloading.

[0071] like Figure 3 and Figure 4As shown, the lens assembly equipment also includes a second component assembly device 5 and a dispensing and curing device 6. The second component assembly device 5 and the dispensing and curing device 6 are mounted on the frame 1. The second component assembly device 5 is located upstream of the first component assembly device 2, and the dispensing and curing device 6 is located between the first component assembly device 2 and the second component assembly device 5. The second component assembly device 5 can assemble the second component into the lens frame to form a second lens semi-finished product. It can be understood that the first lens semi-finished product is formed by assembling the first component into the second lens semi-finished product. The entire assembly process is: lens frame - assemble the second component - second lens semi-finished product - dispensing and curing - assemble the first component - first lens semi-finished product - fixation - lens module. The dispensing and curing device 6 can fix the second component into the lens frame. The dispensing and curing device 6 is provided with at least two dispensing and curing stations. The specific number is set according to the working cycle of the upstream and downstream devices. In this embodiment, there are three dispensing and curing stations. The second lens semi-finished product can be placed on any dispensing and curing station for dispensing and curing, and then go to the downstream first component assembly device 2 for first component assembly. Understandably, the curing cycle of the adhesive is much longer than the assembly cycle of the second part and the assembly cycle of the first part. After the second part assembly device 5 presses the second part into the lens frame to form the second lens semi-finished product, the second lens semi-finished product can be fixed at any adhesive curing station. There is no need for the downstream first part assembly device 2 and the upstream second part assembly device 5 to wait for the intermediate adhesive curing device 6 to work. There is no intermediate waiting time, which improves production efficiency.

[0072] In this embodiment, the dispensing and curing device 6 includes a first conveying mechanism 61, which includes a second driving member 611 and a first gripper 612. The second driving member 611 can be a cylinder or a motor. In this embodiment, the second driving member 611 is a motor, which is mounted on the frame 1. The output end of the motor is connected to a lead screw and nut assembly. The nut of the lead screw and nut assembly is connected to the first gripper 612, which can grip the second lens semi-finished product. After the first gripper 612 grips the second lens semi-finished product, the second driving member 611 drives the first gripper 612 to move between the three dispensing and curing stations and place the second lens semi-finished product at any empty dispensing and curing station. After completing the dispensing and curing process, the second driving member 611 then drives the first gripper 612 to move to the station of the first component assembly device 2 and place the second lens semi-finished product at the station of the first component assembly device 2.

[0073] like Figure 5As shown, both the first component assembly device 2 and the second component assembly device 5 include a third conveying mechanism 56. The third conveying mechanism 56 includes a slide block 561, an eighth drive member 562, and a fourth gripper 563. The slide block 561 is connected to the output end of the sliding drive member. The sliding drive member can be configured as a motor screw or a cylinder push rod. A guide rail extending in the second direction is mounted on the frame 1. A slider is slidably connected to the guide rail. The slide block 561 is fixed on the slider. The eighth drive member 562 can be configured as an electric push rod or a cylinder. In this embodiment, the eighth drive member 562 is a cylinder. The cylinder is mounted on the slide block 561. The number of fourth grippers 563 is the same as the number of mounting bases 52. The fourth grippers 563 are connected to the output end of the cylinder. The cylinder can drive the fourth grippers 563 to rise and fall to take out or place the second lens semi-finished product. When performing the material pulling process, the fourth gripper 563 can grip the second lens semi-finished product on the mounting base 52 of the second component assembly device 5, and then the sliding drive drives the slide 561 to move along the second direction to the position of the mounting base 52 of the first component assembly device 2, and the fourth gripper 563 releases the second lens semi-finished product to place it on the mounting base 52.

[0074] Furthermore, the dispensing and curing device 6 is located on one side of the junction of the first component assembly device 2 and the second component assembly device 5. It has a compact structure, and the first conveying mechanism 61 can transport the second lens semi-finished product from the mounting base 52 to any dispensing and curing station. In this embodiment, a rotary cylinder is also provided between the second driving member 611 and the first gripper 612, enabling the transfer of the second lens semi-finished product between the dispensing and curing station and the mounting base 52. After the second lens semi-finished product completes the dispensing and curing process, the first conveying mechanism 61 transports the second lens semi-finished product back to the mounting base 52. In other embodiments of the present invention, the dispensing and curing device 6 can also be directly positioned between the first component assembly device 2 and the second component assembly device 5, thereby using the third conveying mechanism 56 to perform the material pulling operation of the second component assembly device 5 - dispensing and curing device 6 - first component assembly device 2.

[0075] like Figure 6 and Figure 7As shown, the adhesive dispensing and curing device 6 includes a bracket 62, a lens fixing mechanism 63, a position adjusting mechanism 64, a first dispensing mechanism 65, and a first curing mechanism 66. The lens fixing mechanism 63 is installed at the bottom of the bracket 62 and can fix the second lens semi-finished product to be dispensed with adhesive. The position adjusting mechanism 64 is installed on the bracket 62 and located on one side of the lens fixing mechanism 63. The first dispensing mechanism 65 is connected to the execution end of the position adjusting mechanism 64 and is located diagonally above the lens fixing mechanism 63. The first dispensing mechanism 65 can dispense adhesive onto the second lens semi-finished product. The first curing mechanism 66 is installed at the top of the bracket 62 and located directly above the lens fixing mechanism 63. The first curing mechanism 66 can irradiate the second lens semi-finished product after dispensing with ultraviolet light to cure the adhesive on it. When performing the lens dispensing and curing process, the second lens semi-finished product is fixed to the lens fixing mechanism 63. First, the first dispensing mechanism 65 can move along the direction close to the lens fixing mechanism 63 to dispense adhesive onto the second lens semi-finished product. Then, the first curing mechanism 66 can move along the direction close to the lens fixing mechanism 63 to cure the adhesive on the second lens semi-finished product, thus fixing the second component to the lens frame. In this process, since the first dispensing mechanism 65 and the first curing mechanism 66 are integrated, the structure is compact, and the second lens semi-finished product can be dispensed and cured sequentially at the same station. Moreover, when the lens module model changes and the position of the first dispensing mechanism 65 needs to be adjusted, only the position adjustment mechanism 64 needs to be adjusted, which is simple to operate and improves versatility.

[0076] Specifically, the first dispensing mechanism 65 includes a fifth driving member 651 and a dispensing head 652. The fifth driving member 651 can be a motor or a cylinder. In this embodiment, the fifth driving member 651 is a motor. The output end of the motor is connected to a lead screw and nut pair. The lead screw and nut pair is installed on the execution end of the position adjustment mechanism 64. The dispensing head 652 is connected to the nut of the lead screw and nut pair, so that the motor can drive the dispensing head 652 to move in a direction close to the lens fixing mechanism 63 to dispense glue onto the second lens semi-finished product on the lens fixing mechanism 63.

[0077] Specifically, the first curing mechanism 66 includes a sixth driving component 661 and an ultraviolet lamp 662. The sixth driving component 661 can be a motor or a cylinder. In this embodiment, the sixth driving component 661 is a cylinder, which is mounted on the top of the bracket 62. The ultraviolet lamp 662 is connected to the output end of the cylinder. After the first dispensing mechanism 65 dispenses adhesive to the second lens semi-finished product, the cylinder can drive the ultraviolet lamp 662 to move in a direction close to the lens fixing mechanism 63 to press against the second lens semi-finished product on the lens fixing mechanism 63, thereby using the ultraviolet lamp 662 to irradiate the adhesive to cure the adhesive.

[0078] like Figure 7 and Figure 8As shown, the position adjustment mechanism 64 includes a first adjustment component 641, which includes a first fixed plate 6411 and a first sliding plate 6412. The first fixed plate 6411 has an arc-shaped hole 64111 centered on the second lens semi-finished product on the lens fixing mechanism 63. The first sliding plate 6412 is rotatably mounted within the arc-shaped hole 64111 via a rotating shaft, and a knob is located at the end of the rotating shaft away from the first sliding plate 6412. The first sliding plate 6412 has oblong holes extending radially along the arc-shaped hole 64111. The fifth driving member 651 is adjustablely mounted on the first sliding plate 6412 through these oblong holes. When it is necessary to adjust the relative angle between the dispensing head 652 and the second lens semi-finished product, simply loosen the knob, slide the first sliding plate 6412 on the first fixed plate 6411 to the designated position, and finally tighten the knob again.

[0079] In this embodiment, the position adjustment mechanism 64 further includes a second adjustment component 642, which includes a second fixed plate 6421, a second sliding plate 6422, and a pusher 6423. The second sliding plate 6422 is provided with a sliding platform, and the second fixed plate 6421 is provided with a sliding groove. Both the sliding platform and the sliding groove extend along a first direction, which is a vertical direction. The sliding platform is slidably disposed in the sliding groove so that the second sliding plate 6422 is slidably connected to the second fixed plate 6421. The first fixed plate 6411 is disposed on the second sliding plate 6422. The pusher 6423 can be configured as a lead screw and nut mechanism or a top screw. In this embodiment, the pusher 6423 is a lead screw and nut mechanism. The nut of the lead screw and nut mechanism is fixed to the second fixed plate 6421, and one end of the lead screw can push the second sliding plate 6422 to move along the first direction. Furthermore, a fastening plate 6426 is also fixed on the second fixing plate 6421. A knob 6427 is slidably disposed on the fastening plate 6426 along the first direction. When the second sliding plate 6422 moves along the first direction, the knob 6427 is in a loose state so that the knob 6427 slides on the fastening plate 6426. When the second sliding plate 6422 reaches the designated position, tightening the knob 6427 can fix the second sliding plate 6422 to the designated position on the second fixing plate 6421.

[0080] Specifically, the second adjustment component 642 also includes a rotating plate 6424, which is rotatably connected to the second fixed plate 6421 via a rotating shaft. The pushing direction of the lead screw and nut mechanism is a second direction, which intersects the first direction. In this embodiment, the second direction is perpendicular to the first direction and is horizontal, making it easier to adjust the lead screw and nut mechanism. The rotating plate 6424 is set as a right triangle, and ball bearings 6425 are rotatably arranged on the two right-angled surfaces of the right-angled rotating plate 6424. One ball bearing 6425 abuts against the second sliding plate 6422 along the first direction, and the other ball bearing 6425 abuts against the actuating end of the lead screw and nut mechanism. When it is necessary to adjust the height of the first dispensing mechanism 65, it is only necessary to rotate the lead screw and nut mechanism to push the rotating plate 6424 to rotate. The ball bearings 6425 on the rotating plate 6424 abut against the second sliding plate 6422, which pushes the second sliding plate 6422 to rise and fall along the first direction. The operation is simple. In other embodiments of the present invention, the pushing direction of the pusher 6423 can also be set to the vertical direction, that is, the first direction, and the second sliding plate 6422 can be directly connected to the execution end of the pusher 6423. The pusher 6423 can directly push the second sliding plate 6422 and the first dispensing mechanism 65 to rise and fall.

[0081] In a preferred embodiment, the position adjustment mechanism 64 further includes a third adjustment component 643 and a fourth adjustment component 644. The third and fourth adjustment components 643 and 644 have similar structures to the second adjustment component 642, but differ in that the pushing directions of the pusher 6423 of the third and fourth adjustment components 643 and 644 are respectively the third and second directions. A sliding plate is directly connected to the actuating end of the pusher 6423, enabling the sliding plate to move along the third and second directions respectively. This achieves multi-degree-of-freedom adjustment of the first dispensing mechanism 65, improving its versatility. Specifically, the fourth adjustment component 644 is mounted on the bracket 62, the third adjustment component 643 is connected to the output end of the fourth adjustment component 644, and the second fixing plate 6421 is connected to the output end of the third adjustment component 643.

[0082] like Figure 6 , Figure 9 and Figure 10 As shown, the lens fixing mechanism 63 includes a third driving component 631 and a clamping assembly 632. The third driving component 631 can be a motor or a pneumatic motor. In this embodiment, the third driving component 631 is a motor, which is mounted on the bracket 62. The clamping assembly 632 is connected to the output end of the motor. When the first dispensing mechanism 65 dispenses adhesive onto the second lens semi-finished product, the clamping assembly 632 can clamp the second lens semi-finished product to be dispensed. The motor can drive the clamping assembly 632 and the lens to rotate around the first direction, thereby making the first dispensing mechanism 65 dispense adhesive more evenly and fix it more firmly on the second lens semi-finished product.

[0083] Specifically, the clamping assembly 632 includes a clamping cylinder 6321 and at least two second grippers 6322. The clamping cylinder 6321 is located at the output end of the third drive member 631. The number of second grippers 6322 can be set as needed. In this embodiment, three second grippers 6322 are arranged in a triangular pattern, which makes clamping the second lens semi-finished product more reliable. The three second grippers 6322 are connected to the output end of the clamping cylinder 6321, and the clamping cylinder 6321 can drive the three second grippers 6322 to move closer to each other to clamp the lens.

[0084] In this embodiment, the lens fixing mechanism 63 further includes a connecting block 633. One end of the connecting block 633 is connected to the output end of the third driving member 631. Specifically, the third driving member 631 is a motor, and the output end of the motor is connected to a pulley. The connecting block 633 is also fitted with a pulley, and the two pulleys are connected by a belt drive. The other end is equipped with a clamping cylinder 6321. Furthermore, the connecting block 633 has an air guide hole 6331. One end of the air guide hole 6331 is provided with an air pipe connector 634, which is connected to an external air supply device. The air pipe connector 634 is rotatably connected to the connecting block 633 in a first direction. The other end of the air guide hole 6331 is connected to the clamping cylinder 6321 to supply air to the clamping cylinder 6321. The structure is compact and does not require additional air pipes. Understandably, the motor drives the connecting block 633 to rotate, and the connecting block 633 rotates synchronously with the clamping assembly 632. At this time, the air pipe connector 634 can rotate relative to the connecting block 633 without interference, thus improving reliability.

[0085] like Figure 11As shown, the second component assembly device 5 includes a component feeding mechanism 51, a mounting base 52, a suction mechanism 53, and a second transport mechanism 54. The mounting base 52 is mounted on the frame 1 and located on one side of the third transport mechanism 56. A picture frame can be placed on the mounting base 52. The suction mechanism 53 is mounted on the frame 1 and located above the mounting base 52. The suction mechanism 53 can pick up the second component and press it into the picture frame on the mounting base 52. The second transport mechanism 54 reciprocates between the station of the component feeding mechanism 51 and the station of the suction mechanism 53. When assembling the second component into the frame, the component feeding mechanism 51 first places the second component onto the second conveying mechanism 54. Preferably, the number or type of the second component is at least two. The second conveying mechanism 54 then moves the second component to the station of the suction mechanism 53. The suction mechanism 53 picks up the second component from the second conveying mechanism 54 and presses it one by one into the frame on the mounting base 52. At the same time, the second conveying mechanism 54 returns to the station of the component feeding mechanism 51, enabling the pulling of the next batch of second components. It can be understood that in this embodiment, the feeding, pulling and assembly of the second component are separated into different mechanisms and completed at different stations, which can work synchronously and simultaneously, shortening the assembly cycle of the second component and improving production efficiency.

[0086] Specifically, the parts feeding mechanism 51 includes a robotic arm 511 and trays 512. Two sets of trays 512 are configured, located on either side of the robotic arm 511. A second part can be placed on each tray 512. The actuator of the robotic arm 511 is connected to a suction pen for picking up the second part. Specifically, the robotic arm 511 can pick up the second part from the first set of trays 512 and transfer it to the second conveying mechanism 54. Simultaneously, it can reposition the second part on the idle second set of trays 512. In other words, the first and second sets of trays 512 can cyclically feed parts, eliminating waiting time for the robotic arm 511 and improving feeding efficiency.

[0087] Specifically, the suction mechanism 53 includes a three-axis drive assembly 531 and an adsorption component 532. The adsorption component 532 can be configured as a suction pen or nano-adhesive tape. In this embodiment, the adsorption component 532 is a suction pen, which is connected to the execution end of the three-axis drive assembly 531. The suction pen corresponds one-to-one with the second component on the second transport mechanism 54. When the second transport mechanism 54 moves below the suction mechanism 53, the three-axis drive assembly 531 can drive the suction pen to suck up all the second components at once and then assemble them one by one into the frame on the mounting base 52.

[0088] In this embodiment, the structure of the first component assembly device 2 is the same as that of the second component assembly device 5, and the number of first component assembly devices 2 can be set according to the number of first components. This can be achieved by setting a dispensing and curing device 6 between the first component assembly device 2 and the second component assembly device 5, and then setting a fixing device 3 downstream of the last first component assembly device 2. Specifically, the first component assembly device 2 also includes a component feeding mechanism 51, a mounting base 52, a suction mechanism 53, and a second conveying mechanism 54. The mounting base 52 is mounted on the frame 1 and located on one side of the third conveying mechanism 56. The mounting base 52 can hold the second lens semi-finished product. The suction mechanism 53 is mounted on the frame 1 and located above the mounting base 52. The suction mechanism 53 can suck up the first component and press it onto the second lens semi-finished product on the mounting base 52 to form the first lens semi-finished product. The second conveying mechanism 54 reciprocates between the station of the component feeding mechanism 51 and the station of the suction mechanism 53. When assembling the first component into the second lens semi-finished product, the component feeding mechanism 51 first places the first component onto the second transport mechanism 54, and then the second transport mechanism 54 moves the first component to the station of the suction mechanism 53. The suction mechanism 53 picks up the first component from the second transport mechanism 54 and presses it one by one into the second lens semi-finished product on the mounting base 52.

[0089] like Figure 11 , Figure 12 and Figure 13 As shown, the second component assembly device 5 also includes a sprue detection mechanism 55, which is located upstream of the second conveying mechanism 54 and downstream of the frame feeding device 7. The second conveying mechanism 54 includes a fourth driving member 541 and an adsorption seat 542. The adsorption seat 542 can adsorb the second component and is connected to the output end of the fourth driving member 541. The sprue detection mechanism 55 is communicatively connected to the fourth driving member 541. The fourth driving member 541 can be configured as a motor or a pneumatic motor. In this embodiment, the fourth driving member 541 is a motor, which is mounted on the frame 1. The adsorption seat 542 is connected to the output end of the motor, and the sprue detection mechanism 55 is mounted on the frame 1 and located above the mounting base 52. Specifically, the frame feeding device 7 provides the frame to the mounting base 52. The sprue detection mechanism 55 can detect the sprue position of the frame. Based on this detection result, the fourth driving member 541 drives the adsorption seat 542 to rotate so that the sprue of the second component is aligned with the sprue of the frame, thus improving reliability.

[0090] In a preferred embodiment, at least two adsorption seats 542 are provided. In this embodiment, four adsorption seats 542 are provided. Two shaping plates 544 clamp the four adsorption seats 542, and the two shaping plates 544 are connected to the output end of the ninth driving member 545. The ninth driving member 545 can be configured as an electric actuator or a cylinder. In this embodiment, the ninth driving member 545 is a rodless cylinder. The rodless cylinder can drive the two shaping plates 544 to move closer to each other to clamp the four adsorption seats 542, thereby calibrating the alignment of the four adsorption seats 542 and facilitating the completion of the subsequent assembly process.

[0091] In this embodiment, the adsorption seat 542 is connected to the output end of the fourth drive member 541 via a coupling assembly 543. The coupling assembly 543 includes a connecting sleeve 5431 and an elastic element 5432. The connecting sleeve 5431 has a coupling hole 54311. The output shaft of the fourth drive member 541 is inserted into the coupling hole 54311 and fixed to the side wall of the coupling hole 54311 by a nut screw 5433. The adsorption seat 542 is inserted into the coupling hole 54311. The adsorption seat 542 has a sliding groove extending in a first direction. Another nut screw 5433 passes through the side wall of the coupling hole 54311 and is inserted into the sliding groove, thereby slidably connecting the adsorption seat 542 and the connecting sleeve 5431. The elastic element 5432 can be set as a spring or a spring washer. In this embodiment, the elastic element 5432 is a compression spring. The compression spring is located in the coupling hole 54311 and one end abuts against the output shaft, and the other end abuts against the adsorption seat 542. On the one hand, the coupling assembly 543 has a simple structure, and the fourth driving component 541 can drive the adsorption seat 542 to rotate through the coupling assembly 543; on the other hand, when the robotic arm 511 places the second part on the adsorption seat 542, the elastic component 5432 can play a buffering role to prevent the second part from being crushed by the robotic arm 511.

[0092] like Figure 14 As shown, the fixing device 3 includes a second dispensing mechanism 31 and a second curing mechanism 32 arranged sequentially along a first direction. The structure of the second dispensing mechanism 31 is the same as that of the first dispensing mechanism 65, and the structure of the second curing mechanism 32 is the same as that of the first curing mechanism 66. After the transfer device 4 transfers the first lens semi-finished product from the station of the first component assembly device 2 to the station of the second dispensing mechanism 31, the second dispensing mechanism 31 and the second curing mechanism 32 successively perform dispensing and curing operations on the second lens semi-finished product, thereby forming a lens module. In other embodiments of the present invention, the curing device can also be configured as a hot melt sealing device, which can also fix the second component to the lens frame.

[0093] In this embodiment, the fixing device 3 further includes a third conveying mechanism 56 and a receiving robot. The receiving robot is located on one side of the third conveying mechanism 56, and the second dispensing mechanism 31 and the second curing mechanism 32 are located on the other side of the third conveying mechanism 56. The structure is compact. The third conveying mechanism 56 can move the second lens semi-finished product from the station of the first component assembly device 2 to the station of the second dispensing mechanism 31, and then transfer it between the various stations inside the fixing device 3. The receiving robot is used to receive the lens module. Since the stroke of the receiving robot is limited, the lens assembly equipment also provides a rotary transfer mechanism 33 at the end of the third conveying mechanism 56. The rotary transfer mechanism 33 includes a seventh drive member 331 and a third gripper 332. The seventh drive member 331 can be a motor or a rotary cylinder. In this embodiment, the seventh drive member 331 is a rotary cylinder, and the third gripper 332 is connected to the output end of the rotary cylinder. After the second curing mechanism 32 cures the second lens semi-finished product to form a lens module, the third gripper 332 faces one side of the second curing mechanism 32 and grips the lens module. The rotary cylinder drives the third gripper 332 to rotate toward the receiving robot to compensate for the stroke of the receiving robot.

[0094] The working process of lens assembly equipment:

[0095] The lens frame feeding device 7 provides the lens frame onto the mounting base 52, and the sprue detection mechanism 55 detects the sprue position of the lens frame. The robotic arm 511 transfers the second component from the tray 512 to the second transport mechanism 54. The fourth drive unit 541 drives the second component to rotate and align it with the sprue of the lens frame. The second transport mechanism 54 then transfers the second component to the suction mechanism 53, which picks up the second component from the second transport mechanism 54 and presses it onto the lens frame to form a second lens semi-finished product. Then, the third transport mechanism 56 transfers the second lens semi-finished product to the mounting base 52 at the first component assembly device 2. The first transport mechanism 61 transfers the second lens semi-finished product to the dispensing and curing station for dispensing and curing. After the first lens semi-finished product has cured, the first transport mechanism 61 transfers the second lens semi-finished product back to the mounting base 52 at the first component assembly device 2. The first component is assembled onto the second component semi-finished product to form the first component semi-finished product. The first lens semi-finished product is placed on the first transfer unit 421. The first driving component 41 drives the first transfer unit 421 and the second transfer unit 422 to switch positions, transferring the first lens semi-finished product from the station of the first component assembly device 2 to the station of the fixing device 3. The fixing device 3 can fix the first component to the lens frame. Then the first component assembly device 2 can continue to produce the first lens semi-finished product without waiting for the fixing device 3 to work. Driven by the first driving component 41, the second transfer unit 422 then transfers the next first lens semi-finished product from the station of the first component assembly device 2 to the station of the fixing device 3, saving the material transfer time from the station of the first component assembly device 2 to the station of the fixing device 3. At the same time, the first transfer unit 421 resets to the station of the first component assembly device 2. The overall assembly process is continuous and improves production efficiency.
