[0023] This invention provides a lens assembly device for assembling a first component and a second component, wherein the first component may be a front lens cap and the second component may be a rear lens cap; of course, the first component and the second component may also be other components that need to be glued together.

[0024] Please refer to Figure 1 , Figures 4 to 6 The lens assembly equipment includes a conveyor module 100, a dispensing module 200, a feeding module 300, and a pressing module 400. The conveyor module 100 is adapted to convey a fixture along the conveying direction, the fixture carrying a first component. The conveyor module 100 is sequentially provided with a dispensing station and a pressing station along the conveying direction. The dispensing module 200 is located above the dispensing station and is used for dispensing adhesive onto the first component. The feeding module 300 is used for feeding a second component. The pressing module 400 is located above the pressing station and is used for pressing. Module 400 includes a press-fit drive mechanism 410 and a gripper mechanism 420. The gripper mechanism 420 is connected between the press-fit station and the feeding module 300 and is suitable for handling the second part. The gripper mechanism 420 includes a mounting plate assembly 421, a pressing gripper assembly 422 and a pressure sensor 423. The pressing gripper assembly 422 is floatingly connected to the mounting plate assembly 421 along a first direction. The pressure sensor 423 is disposed between the mounting plate assembly 421 and the pressing gripper assembly 422 and extends along the first direction.

[0025] According to an embodiment of the lens assembly equipment of the present invention, a fixture carrying a first component is sequentially conveyed by a conveyor module 100 to a dispensing station and a pressing station along the conveying direction; when the fixture reaches the dispensing station, the dispensing module 200 dispenses adhesive at a designated position on the first component, and then the fixture continues to move to the pressing station; simultaneously, the loading module 300 supplies a second component, and the gripper mechanism 420 of the pressing module 400 grips the second component from the loading module 300 and transports it above the first component at the pressing station; subsequently, the pressing... The drive mechanism 410 drives the gripper mechanism 420 to move downward as a whole, so that the pressing gripper assembly 422 directly presses against the second part and presses against the first part. During this pressing process, the pressing gripper assembly 422 generates a slight floating displacement relative to the mounting plate assembly 421 in the first direction due to the pressing force, thereby compressing the pressure sensor 423 set between the mounting plate assembly 421 and the pressing gripper assembly 422. The pressure sensor 423 detects the pressure in real time and feeds the pressure signal back to the control system to realize closed-loop control of the pressing process.

[0026] According to the lens assembly equipment of the present invention, by floatingly connecting the pressure gripper assembly 422 to the mounting plate assembly 421 and integrating the pressure sensor 423, the gripper mechanism 420 can not only complete the picking, placing and transporting of the second part, but also directly perform pressure pressing on the first part, saving the space of additional dedicated pressing equipment, effectively reducing the overall size of the equipment and reducing manufacturing costs; at the same time, the real-time force feedback of the pressure sensor 423, combined with the floating compensation function of the pressure gripper assembly 422, can accurately control the magnitude of the pressing force to avoid excessive pressure damaging the part or insufficient pressure causing poor adhesion, significantly improving the yield and consistency of lens assembly.

[0027] In this embodiment, the floating connection can be achieved through slide rails, slide tables, slide grooves, etc.

[0028] In some embodiments, combined with Figure 2 As shown, the loading module 300 includes a pallet lifting mechanism 310 and a pallet pushing and pulling mechanism 320. The pallet pushing and pulling mechanism 320 is connected to the discharge end of the pallet lifting mechanism 310 and has a loading station. The pallet lifting mechanism 310 includes a pallet platform 311 and a platform lifting drive 312. The pallet platform 311 is suitable for placing a magazine 313. The magazine 313 has multiple placement slots arranged along a first direction. The placement slots are suitable for placing a pallet. The pallet carries several second accessories. The platform lifting drive 312 is suitable for driving the pallet platform 311 to lift and lower so that the pallet is connected to the pallet pushing and pulling mechanism 320. The pallet pushing and pulling mechanism 320 is suitable for pushing and pulling the pallet between the loading station and the placement slots.

[0029] In this embodiment, during the operation of the feeding module 300, the pallet platform 311 of the pallet lifting mechanism 310 pre-places a magazine 313. Multiple placement slots are arranged in layers along the first direction (Z direction in the figure) within the magazine 313, each slot holding a pallet, and each pallet carrying several second accessories. When a second accessory needs to be supplied, the platform lifting drive 312 drives the pallet platform 311 to rise and fall, aligning the height of the target pallet in the magazine 313 with the pallet pushing and pulling mechanism 320. Subsequently, the pallet pushing and pulling mechanism 320... Action 20 pulls the tray out of the placement slot of the magazine 313 to the loading station of the tray push-pull mechanism 320, so that the gripper mechanism 420 of the press module 400 can grab the second part from the loading station; after the second part on the tray is taken, the tray push-pull mechanism 320 pushes the empty tray back into the original placement slot of the magazine 313, and the platform lifting drive 312 continues to drive the tray platform 311 to rise and fall to the height of the next layer of trays, repeating the above pulling action, thereby realizing the continuous and automatic supply of the second part of multiple layers of trays.

[0030] In this embodiment, the lifting drive component 312 is used to precisely control the lifting of the pallet platform 311, so that the pallets of different layers are connected to the pallet push-pull mechanism 320 one by one. This achieves large-capacity, continuous material supply for the second accessory, greatly reduces the frequency of manual pallet replacement, reduces operation intervention time, and improves the automation level and production efficiency of the whole machine.

[0031] In this embodiment, the platform lifting drive 312 can be a cylinder, a slide module, a lead screw module, etc.

[0032] In some embodiments, combined with Figure 2 As shown, the pallet push-pull mechanism 320 includes a support rail 321, a push-pull linear module 322, and a push-pull head 323. The push-pull linear module 322 is adapted to drive the push-pull head 323 to reciprocate. The pallet is provided with a snap-fit ​​groove that engages with the push-pull head 323. The support rail 321 is parallel to the push-pull linear module 322 and is adapted to support the pallet.

[0033] In this embodiment, when the pallet push-pull mechanism 320 is working, the push-pull linear module 322 drives the push-pull head 323 to move towards the magazine 313 to above or below the latching slot of the pallet. Then, the pallet is raised and lowered so that the latching slot engages with the push-pull head 323. After the push-pull head 323 engages with the pallet, the push-pull linear module 322 drives the push-pull head 323 in the opposite direction, and the push-pull head 323 pulls the pallet along the support rail 321 to smoothly pull the pallet out of the magazine 313's placement slot to the loading station on the support rail 321. When the second accessory on the pallet is removed, the push-pull linear module 322 drives the push-pull head 323 again to push the pallet in the opposite direction, and pushes the pallet back into the original placement slot of the magazine 313 along the support rail 321. Then, the pallet is raised and lowered so that the push-pull head 323 disengages from the latching slot, completing the loading cycle of a single-layer pallet.

[0034] In this embodiment, the push-pull head 323 engages with the pallet's slot, and combined with the linear drive of the push-pull linear module 322 and the support rail 321, a fast and reliable connection and separation between the pallet and the push-pull mechanism is achieved. The structure is simple and the transmission is direct. Compared with the method of using a multi-axis robotic arm to grasp or a complex clamping structure, the manufacturing and debugging costs of the equipment are significantly reduced. The setting of the support rail 321 ensures that the pallet moves straight and without swaying during the push-pull process, avoiding the problem of pallet jamming or tilting that could lead to pallet damage or displacement of the second part, and improving the stability and positional accuracy of the loading.

[0035] In this embodiment, the pallet can also be fixed during the handling process by means of gripping with claws, suction cup adsorption, etc.

[0036] In this embodiment, the push-pull linear module can be a slide module, a lead screw module, a cylinder, etc.

[0037] In some embodiments, combined with Figure 3 As shown, the dispensing module 200 includes a dispensing drive mechanism 210 and a dispensing head 220. The dispensing drive mechanism 210 is adapted to drive the dispensing head 220 to move in three-dimensional space. The dispensing drive mechanism 210 includes a Y-axis dispensing linear module 211, an X-axis dispensing linear module 212, and a Z-axis dispensing lifting module 213 arranged perpendicularly to each other. The X-axis dispensing linear module 212 is parallel to the conveying direction. It adapts to the changes in dispensing position and height of different models of first accessories, and meets the complex dispensing requirements such as multi-point and irregular trajectory.

[0038] In other embodiments, the dispensing drive mechanism 210 may also be driven by a robotic arm.

[0039] In some embodiments, combined with Figure 3As shown, the dispensing module 200 also includes a dispensing vision camera 230 and a dispensing height measuring component 240, which are connected to the movable end of the dispensing drive mechanism 210. The detection field of view of the dispensing vision camera 230 and the transmitting end of the dispensing height measuring component 240 are both facing the first accessory.

[0040] In this embodiment, the dispensing module 200 integrates the dispensing vision camera 230 and the dispensing height measuring component 240 into the movable end of the dispensing drive mechanism 210, so that the two move together with the dispensing head 220. Before dispensing, the visual positioning and surface height detection of the first part can be completed. The dispensing vision camera 230 collects position and posture deviations to guide the trajectory correction of the dispensing head 220, and the dispensing height measuring component 240 detects the actual height to automatically compensate for the Z-axis spacing. This compensates for the fixture positioning error and the part size tolerance, improves the dispensing position accuracy and glue quantity consistency, and enhances the equipment's ability to quickly adapt to different product models.

[0041] In this embodiment, the dispensing height measuring component 240 can be a laser rangefinder, an acoustic rangefinder, or the like.

[0042] In some embodiments, combined with Figure 1 and Figure 4 As shown, the lens assembly equipment also includes a dispensing positioning module 500, which is located adjacent to the conveyor line module 100. The dispensing positioning module 500 includes a dispensing positioning component 510, a dispensing positioning lifting drive component 520, and a dispensing pressure plate 530. The dispensing positioning component 510 is located adjacent to the dispensing station and is suitable for detecting the position of the fixture. The dispensing pressure plate 530 is located above the first component at the dispensing station. The dispensing positioning component 510 is communicatively connected to the dispensing positioning lifting drive component 520. The dispensing pressure plate 530 is suitable for pressing and fixing the first component under the drive of the dispensing positioning lifting drive component 520.

[0043] In this embodiment, when the conveyor module 100 transports the fixture carrying the first component to the dispensing station, the dispensing positioning component 510, located on the side of the dispensing station, detects the position of the fixture to obtain the fixture's positioning status. The dispensing positioning component 510 transmits the detection signal to the dispensing positioning lifting drive component 520 in real time. The dispensing positioning lifting drive component 520 then drives the dispensing pressure plate 530 located above the first component to move downward, so that the dispensing pressure plate 530 presses vertically against the first component or the fixture, thereby firmly fixing the first component at the dispensing station. After the dispensing module 200 completes the dispensing operation, the dispensing positioning lifting drive component 520 drives the dispensing pressure plate 530 to retract upward, releasing the pressing state on the first component, and the fixture can continue to move towards the pressing station along the conveying direction.

[0044] In this embodiment, the position of the fixture is detected by the dispensing positioning component 510 before dispensing, and the dispensing pressure plate 530 is linked to actively press down and fix the first component. This effectively eliminates the positional deviation caused by the start-stop inertia of the conveyor module 100, the gap between the fixture and the track, and the manufacturing tolerance of the fixture itself. This ensures that the first component remains absolutely stationary during the dispensing process and avoids defects such as glue line deviation and uneven glue distribution caused by fixture shaking or component micro-movement.

[0045] In this embodiment, the dispensing positioning and lifting drive 520 is a cylinder, but it can also be a lead screw module, a slide module, etc.

[0046] In this embodiment, the dispensing pressure plate 530 is a U-shaped plate that is detachably connected to the movable end of the dispensing positioning and lifting drive component 520. Different structures of the dispensing pressure plate 530 can be replaced based on different first accessories. The detachable connection can be a bolt connection, a snap-fit ​​connection, an adhesive connection, etc.

[0047] In this embodiment, the dispensing positioning component 510 can be a laser sensor, an infrared sensor, a Hall sensor, etc.

[0048] In some embodiments, combined with Figure 1 and Figure 4 As shown, the lens assembly equipment also includes a press-fit positioning module 600, which is located on the side of the conveyor module 100. The press-fit positioning module 600 includes a press-fit positioning lifting drive 610 and a press-fit positioning gripper 620. The press-fit positioning gripper 620 is located above the first part at the press-fit station. The press-fit positioning gripper 620 is adapted to be lifted and lowered under the drive of the press-fit positioning lifting drive 610, and to open and close along the conveying direction to clamp and position the first part.

[0049] In this embodiment, when the conveyor module 100 conveys the fixture, which has completed dispensing and carries the first component, to the pressing station, the pressing positioning lifting drive 610 drives the pressing positioning gripper 620, which is located above the first component, to descend vertically to the working height. Subsequently, the pressing positioning gripper 620 clamps the first component from both sides towards the middle along the conveying direction (X direction in the figure), and accurately positions and fixes the first component at the pressing station through bidirectional opening and closing clamping action. After the gripper mechanism 420 of the pressing module 400 moves the second component above the first component and completes the pressing, the pressing positioning gripper 620 opens to release the first component, and the pressing positioning lifting drive 610 drives it to rise and retract, so that the fixture can continue to be conveyed along the conveying direction.

[0050] In this embodiment, the first component is clamped and positioned before pressing, which effectively overcomes the positional drift in the conveying direction caused by the accumulation of gaps between the fixture and the track during multiple start-stop cycles of the conveyor module 100. This ensures that the central axis of the first component and the pressing axis of the second component are highly coincident during pressing, avoiding problems such as pressing tilt, damage, or incomplete pressing caused by horizontal offset. At the same time, the pressing positioning gripper 620 clamps bidirectionally from both sides of the conveying direction. Compared with single-sided positioning or blocking methods, it can adaptively eliminate the positive and negative errors of the first component in the conveying direction, making the positioning accuracy after clamping higher and more reliable.

[0051] In this embodiment, the press-fitting positioning and lifting drive 610 is a cylinder, but it can also be a lead screw module, a slide module, etc.

[0052] In some embodiments, combined with Figure 4 As shown, the conveyor module 100 includes a processing conveyor line 110 and a temporary conveyor line 120. The processing conveyor line 110 is provided with a dispensing station and a pressing station. The temporary conveyor line 120 is connected to the end of the processing conveyor line 110 along the conveying direction.

[0053] In this embodiment, the processing conveyor line 110 is used to carry the fixture through the dispensing station and the pressing station to complete the core assembly process. The temporary storage conveyor line 120 serves as a buffer to receive the pressed products, so that the processing conveyor line 110 does not need to stop and wait due to the difference in the cycle time of subsequent processes (such as glue curing, quality inspection or material queuing). This ensures that the dispensing and pressing processes can run continuously and without interruption, which significantly improves the cycle time efficiency and equipment utilization of the entire production line.

[0054] In this embodiment, the conveyor module 100 may further include a return conveyor line 130, which is arranged parallel to the processing conveyor line 110 and is suitable for returning the fixtures of subsequent processes to the upstream equipment for reuse in loading the first part.

[0055] In some embodiments, combined with Figure 6 As shown, the gripper mechanism 420 also includes an NG gripper assembly 424 and an NG gripper drive 425. The NG gripper assembly 424 is connected to the mounting plate assembly 421 via the NG gripper drive 425. The NG gripper assembly 424 is adapted to move up and down in a first direction under the drive of the NG gripper drive 425 to switch between a storage position and a clamping position. The storage position is the position where the NG gripper assembly 424 avoids the position of the second accessory clamped by the pressing gripper assembly 422, and the clamping position is the position where the NG assembly clamped by the NG gripper assembly 424 avoids the position of the pressing gripper assembly 422. The lens assembly equipment also includes an NG placement stage 700, and the NG gripper assembly 424 is connected to the NG placement stage 700 and the press-fitting station.

[0056] In this embodiment, after the pressing jaw assembly 422 of the pressing module 400 completes the pressing of the second part and the first part, if the detection system determines that the assembly is an NG assembly, the NG jaw drive 425 drives the NG jaw assembly 424 to descend from the storage position to the clamping position along the first direction, and the NG jaw assembly 424 clamps the NG assembly; then the NG jaw assembly 424 carries the NG assembly to the NG placement stage 700, and then the NG jaw assembly 424 is driven by the NG jaw drive 425 to rise back to the storage position, so as to avoid the normal handling and pressing action of the pressing jaw assembly 422 on the next second part; when the pressing jaw assembly 422 is working normally, the NG jaw assembly 424 is always in the storage position to ensure that it will not interfere with the second part clamped by the pressing jaw assembly 422.

[0057] In this embodiment, the NG gripper assembly 424 is driven to move up and down between the storage position and the clamping position by the NG gripper drive 425, realizing the online automatic sorting and rejection of NG assemblies. There is no need to set up an additional independent defective product unloading robot or conveying mechanism. The reuse of the press-fitting drive mechanism 410 effectively reduces the equipment footprint and manufacturing cost.

[0058] In this embodiment, the NG gripper drive 425 is a cylinder; however, it could also be a lead screw module, a slide module, etc. In some embodiments, combined with Figure 5 As shown, the pressing drive mechanism 410 includes a Y-axis pressing linear module 411, an X-axis pressing linear module 412, and a Z-axis pressing lifting module 413 arranged perpendicularly to each other. The X-axis pressing linear module 412 is parallel to the conveying direction. The orthogonal layout of the three axes enables flexible spatial trajectory planning of the gripper mechanism 420 during material picking, pressing, and obstacle avoidance.

[0059] In other embodiments, the gripper mechanism 420 can also be moved by a robotic arm.

[0060] In some embodiments, combined with Figure 1As shown, the lens assembly equipment also includes a lower camera module 800, which is located below the moving path of the gripper mechanism 420. When the gripper mechanism 420 picks up the second part from the pallet loading station and transports it to the pressing station, it passes above the lower camera module 800. At this time, the lower camera module 800 can quickly take pictures of the bottom of the second part to identify whether there are appearance defects such as scratches, dirt, chipping, and cracks on its surface. This achieves online full inspection of the appearance quality of the incoming material, avoiding defective products from flowing into the pressing process and causing glue waste and yield loss. At the same time, the lower camera module 800 can also scan the product code (such as a QR code or DM code) preset on the bottom of the second part, bind and record the product identity information with the assembly data of the corresponding first part, realize the traceability of quality information of individual products, and facilitate the accurate location and process analysis of subsequent defective products.

[0061] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention 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 invention.
