Description

Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to a rotating lens element adjustment feeding mechanism, belonging to the field of optical lens manufacturing technology. Background Technology

[0002] The assembly process of lens components (such as lenses, lens mounts, filters, etc.) requires extremely high precision and efficiency. To achieve continuous operation of multiple processes, the industry generally adopts rotary multi-station machining systems. Currently, in rotary machining systems, the mainstream solution for the lens component feeding stage at each assembly station is to use a linear conveyor structure to supply components. Specifically, the conveying path of the feeding mechanism is linear, and the direction of this linear conveying is perpendicular to the tangent direction at the corresponding feeding station of the rotary table. That is, the extension of the linear conveying path is perpendicular to the tangent of the rotary table at that station, and the conveying direction is opposite to the tangent movement direction of the station when the rotary table rotates. The original intention of this design is to push the lens components along a fixed linear trajectory to the positioning fixture of the rotary table through linear drive components (such as linear modules, cylinder push rods, etc.), ensuring that the components can accurately align with the rotary table station.

[0003] However, this linear conveying method, which is perpendicular to the tangent of the turntable, has revealed significant drawbacks in practical applications:

[0004] Because the linear conveying direction is forcibly bound to the turntable tangent in a reverse perpendicular relationship, the installation position of the feeding mechanism is strictly limited to the direction perpendicular to the tangent of the corresponding station on the turntable. It is impossible to flexibly adjust the feeding position according to the overall layout of the production line, the size of the workshop space, or the position requirements of other stations (such as feeding and inspection stations). In scenarios with multiple stations densely arranged, the fixed feeding position is prone to spatial interference with the mechanisms of adjacent stations (such as gripping robotic arms and detection sensors), resulting in a significant reduction in the flexibility of equipment layout and difficulty in adapting to the processing requirements of lens components of different specifications.

[0005] To ensure that lens components are stably transported to the turntable station along a straight path, the linear conveyor mechanism needs to reserve sufficient conveying stroke (covering functional sections such as component storage, positioning, and pushing). Moreover, the direction of this stroke is at a fixed angle to the radial direction of the turntable, which requires the feeding mechanism to extend a long structure outward from the turntable. In addition, the constraint that the linear conveying path is perpendicular to the tangent of the turntable makes it impossible for the feeding mechanism to be compactly adapted to the radial or tangential direction of the turntable. This results in a significant increase in the horizontal space occupied by the entire turntable processing equipment, which is not only detrimental to the miniaturization design of the equipment, but also increases the rental cost of the production site and the difficulty of equipment handling and installation, making it difficult to meet the integration requirements of a compact production line.

[0006] To address this issue, a rotating lens element adjustment and feeding mechanism was designed. Utility Model Content

[0007] The main purpose of this invention is to provide a rotating lens element adjustment and feeding mechanism to solve the problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0010] A limiting ring is fitted on the outer side of the mounting base, and the limiting ring is rotatably connected to the mounting base;

[0011] A mounting plate is horizontally fixed to the outside of the limiting ring. A prompting component is provided at the top of the mounting plate near the limiting ring to indicate the adjustment position of the mounting plate.

[0012] A fixing component is provided at the end of the mounting plate away from the limiting ring to fix the position of the mounting plate;

[0013] The top of the mounting plate is provided with a linear conveying assembly along its length, and a transfer assembly is fixed on one side of the mounting base for transferring the workpiece from the top of the transfer tray to the top of the turntable.

[0014] Preferably, the prompting component includes a sliding sleeve, a plug, a slot, and a return spring. The sliding sleeve is fixed to the top of the mounting plate. The plug is slidably disposed inside the sliding sleeve. A return spring is provided between the plug and the inner end of the sliding sleeve. The end of the plug is tapered. A slot that mates with the plug is provided circumferentially on the outer side of the top of the mounting base.

[0015] Preferably, the fixing component includes an extrusion block, a slide rod, a lifting screw, a threaded hole, and an adjustment port. The extrusion block is located at the bottom of the mounting plate. Both ends of the top of the extrusion block are vertically fixed with slide rods. The slide rods are vertically slidably connected to the mounting plate. The end of the mounting plate is rotatably mounted with a lifting screw. The top of the extrusion block has a threaded hole that mates with the lifting screw. The top of the lifting screw has an adjustment port.

[0016] Preferably, the linear conveying assembly includes a first bracket, which is fixed to the top of the mounting plate. A first guide groove is provided on the side of the first bracket along its length. A first slider is slidably arranged inside the first guide groove. A conveying screw is rotatably installed between the two ends of the first guide groove. The conveying screw is threadedly connected to the first slider. A conveying motor for driving the conveying screw is installed at the end of the first bracket. A first vertical cylinder is vertically arranged on the outside of the first slider. A first pneumatic chuck is installed at the output end of the first vertical cylinder.

[0017] Preferably, the transfer assembly includes a second bracket, which is fixed to one side of the top of the mounting base. A second guide groove is provided on the side of the second bracket along the length direction. A second slider is slidably arranged inside the second guide groove. A translation cylinder is installed at the end of the second bracket. The output end of the translation cylinder is connected to the second slider. A second vertical cylinder is installed on the side of the second slider. A second pneumatic chuck is installed at the output end of the second vertical cylinder.

[0018] Preferably, the inner side of the jaws of the second pneumatic chuck is wrapped with an elastic buffer layer made of silicone material to prevent surface damage when clamping lens components.

[0019] Preferably, an annular groove is provided on the outer side of the top of the mounting base, a limiting ring is embedded in the annular groove, and the limiting ring is flush with the outer surface of the mounting base.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model, through its innovative design of a rotatable transfer tray, a mounting plate that can rotate around the mounting base, and matching transfer components, completely breaks the inherent limitation of traditional feeding mechanisms where the linear conveying direction and the tangent of the turntable are forcibly bound in opposite directions. By rotating the mounting plate, the relative angle between the top linear conveying component and the processing turntable can be flexibly adjusted, and the linear conveying component can even be adjusted to be parallel to the tangent of the turntable. This frees the installation position of the feeding mechanism from fixed direction restrictions, allowing it to be freely adapted according to the overall layout of the production line, the size of the workshop space, and the positional requirements of adjacent workstations such as unloading and inspection, effectively avoiding the limitations of traditional fixed orientations. The spatial interference between the feeding position and adjacent mechanisms such as the gripping robotic arm and detection sensors significantly improves the layout flexibility of the equipment in scenarios with dense multi-station layouts. At the same time, the components are first rotated and adjusted in position by the transfer tray, and then the transfer component achieves short-distance precise transfer to the processing turntable. Unlike traditional linear conveyor mechanisms, there is no need to reserve excessive extension stroke, which significantly reduces the horizontal space occupied by the feeding mechanism and thus reduces the overall size of the turntable processing equipment. This not only facilitates the miniaturization design of the equipment, but also reduces the cost of production site rental and the difficulty of equipment handling and installation, and is more suitable for the integration needs of compact production lines.

[0022] 2. This utility model uses a prompting component consisting of a sliding sleeve, insert block, slot, and return spring to quickly and easily locate the rotation position of the mounting plate. In addition, with the fixing component consisting of an extrusion block, sliding rod, lifting screw, threaded hole, and adjustment port, after the mounting plate is adjusted to the target angle, the lifting screw drives the sliding rod to tighten the extrusion block, thus reliably locking the position of the mounting plate and avoiding feeding deviation caused by mounting plate offset during equipment operation. The two components work together to ensure the adjustment accuracy and stability of the mounting plate. Attached Figure Description

[0038] Example 1

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a rotary lens element adjustment and feeding mechanism, including a mounting base 1 fixed to the side of the turntable, a transfer disk 2 horizontally rotatably mounted on the top of the mounting base 1, and a drive motor for driving the transfer disk 2 to rotate is provided on the inner top of the mounting base 1.

[0040] Mounting base 1 is fixed to the side of the machining turntable, providing stable support for the entire mechanism. After the drive motor at the top of mounting base 1 is started, it drives the transfer plate 2, which is horizontally mounted at the top, to rotate. The transfer plate 2 serves as a temporary transfer carrier for workpieces. It can adjust its position of carrying workpieces by rotating, so as to prepare for the angle adaptation when transferring workpieces to the machining turntable in the future.

[0041] A limiting ring 3 is fitted on the outer side of the mounting base 1, and the limiting ring 3 is rotatably connected to the mounting base 1.

[0042] A mounting plate 4 is horizontally fixed to the outer side of the limiting ring 3. A prompting component 5 is provided at the top of the mounting plate 4 near the limiting ring 3. This component is used to prompt the adjustment position of the mounting plate 4. When the mounting plate 4 is rotated and adjusted, the component can provide real-time prompts on its adjustment position, assisting the operator in quickly finding the target angle.

[0043] A fixing component 6 is provided at the end of the mounting plate 4 away from the limiting ring 3, which is used to fix the position of the mounting plate 4. After the mounting plate 4 is adjusted to a suitable angle, its position can be fixed to prevent the mounting plate 4 from shifting during equipment operation.

[0044] The top of the mounting plate 4 is provided with a linear conveying assembly 7 along the length direction, which is responsible for conveying the lens components to be processed (such as lenses, lens mounts, etc.) to the designated position along a linear trajectory. A transfer assembly 8 is fixed on one side of the mounting base 1, which is used to transfer the workpiece on the top of the transfer tray 2 to the top of the turntable. It undertakes the task of grabbing the workpiece carried on the top of the transfer tray 2 and transferring it to the corresponding workstation on the top of the processing turntable, thus completing the key transfer link of the loading process.

[0045] When the rotary lens element adjustment and feeding mechanism is working, firstly, based on the production line layout, workshop space, and the requirements of adjacent workstations, with the mounting base 1 as the center, the limiting ring 3 adapted to the mounting base 1 is rotated to drive the mounting plate 4, which is horizontally fixed outside the limiting ring 3, to perform circumferential angle adjustment. During the adjustment process, the prompting component 5 on the top of the mounting plate 4 provides prompts for the mounting plate 4 to find the correct angle. After the angle is determined, the fixing component 6 at the end of the mounting plate 4 is used to fix the position of the mounting plate 4. Subsequently, the linear conveying component 7 on the top of the mounting plate 4 is activated to grab the lens element to be processed and convey it to the top of the transfer tray 2 in a straight line. The drive motor in the mounting base 1 drives the transfer tray 2 to rotate to adjust the posture of the element. Finally, the transfer component 8 on one side of the mounting base 1 operates to grab the element on the transfer tray 2 and accurately transfer it to the corresponding workstation on the top of the processing turntable, completing one feeding process. After that, each component is reset and enters the next cycle.

[0046] Example 2

[0047] The solution in Example 1 will be further described below with reference to its specific working method.

[0048] like Figure 2 As shown, in a preferred embodiment, based on the above method, the prompting component 5 further includes a sliding sleeve 501, a plug 502, a slot 503 and a return spring 504. The sliding sleeve 501 is fixed to the top of the mounting plate 4. The plug 502 is slidably disposed inside the sliding sleeve 501. A return spring 504 is provided between the plug 502 and the inner end of the sliding sleeve 501. The end of the plug 502 is tapered. A slot 503 that mates with the plug 502 is provided circumferentially on the outer side of the top of the mounting base 1.

[0049] When the mounting plate 4 is rotated, the insert 502 slides against the top outer surface of the mounting base 1 under the action of the return spring 504. When the mounting plate 4 is rotated to the preset angle, the insert 502 is inserted into the corresponding slot 503 under the action of the elastic force. The angle is indicated to the operator by the "click" or a slight "click" sound, so as to realize the quick positioning of the mounting plate 4 adjustment position.

[0050] like Figure 3As shown, in a preferred embodiment, based on the above method, the fixing component 6 further includes a pressing block 601, a sliding rod 602, a lifting screw 603, a threaded hole 604, and an adjustment port 605. The pressing block 601 is located at the bottom of the mounting plate 4. The sliding rod 602 is vertically fixed at both ends of the top of the pressing block 601. The sliding rod 602 is vertically slidably connected to the mounting plate 4. The lifting screw 603 is rotatably mounted at the end of the mounting plate 4. The top of the pressing block 601 is provided with a threaded hole 604 that cooperates with the lifting screw 603. The top of the lifting screw 603 is provided with an adjustment port 605.

[0051] After the angle of the mounting plate 4 is adjusted, the lifting screw 603 is rotated by inserting a tool into the adjustment port 605. Under the action of the threaded engagement, the lifting screw 603 drives the extrusion block 601 to move downward along the slide rod 602 until the extrusion block 601 is tightly attached to the worktable surface of the equipment (or the bottom support structure of the mounting base 1). The position of the mounting plate 4 and the limiting ring 3 is fixed by friction, so as to prevent the mounting plate 4 from shifting due to vibration and other factors when the equipment is running.

[0052] like Figure 4 As shown, in a preferred embodiment, based on the above method, the linear conveying assembly 7 further includes a first bracket 701, which is fixed to the top of the mounting plate 4. A first guide groove 702 is provided on the side of the first bracket 701 along the length direction. A first slider 703 is slidably arranged inside the first guide groove 702. A conveying screw 704 is rotatably installed between the two ends of the first guide groove 702. The conveying screw 704 is threadedly connected to the first slider 703. A conveying motor 705 for driving the conveying screw 704 is installed at the end of the first bracket 701. A first vertical cylinder 706 is vertically arranged on the outside of the first slider 703. A first pneumatic chuck 707 is installed at the output end of the first vertical cylinder 706.

[0053] During operation, the first pneumatic chuck 707 descends under the drive of the first vertical cylinder 706, clamping the lens element to be transported. Then, the first vertical cylinder 706 drives the element to rise and reset. Subsequently, the conveying motor 705 starts, driving the conveying screw 704 to rotate. Through threaded transmission, the first slider 703 slides along the first guide groove 702 towards the transfer disk 2. When it slides to a preset position above the transfer disk 2, the first vertical cylinder 706 descends again, the first pneumatic chuck 707 releases, and the lens element is placed on top of the transfer disk 2, completing the linear transport process of the element.

[0054] like Figure 5As shown, in a preferred embodiment, based on the above method, the transfer assembly 8 further includes a second bracket 801, which is fixed to one side of the top of the mounting base 1. A second guide groove 802 is provided on the side of the second bracket 801 along the length direction. A second slider 803 is slidably arranged inside the second guide groove 802. A translation cylinder 804 is installed at the end of the second bracket 801. The output end of the translation cylinder 804 is connected to the second slider 803. A second vertical cylinder 805 is installed on the side of the second slider 803. A second pneumatic chuck 806 is installed at the output end of the second vertical cylinder 805.

[0055] When the transfer disk 2 rotates to the position corresponding to the transfer assembly 8, the translation cylinder 804 drives the second slider 803 to move along the second guide groove 802 toward the transfer disk 2. At the same time, the second vertical cylinder 805 drives the second pneumatic chuck 806 to descend and clamp the lens element on the transfer disk 2. Then the second vertical cylinder 805 rises, and the translation cylinder 804 drives the second slider 803 to reset toward the machining turntable. When it moves above the corresponding station on the machining turntable, the second vertical cylinder 805 descends again, and the second pneumatic chuck 806 releases, placing the element in the positioning fixture of the machining turntable, thus completing the transfer of the element from the transfer disk 2 to the machining turntable.

[0056] like Figure 5 As shown, in a preferred embodiment, based on the above method, the inner side of the gripper of the second pneumatic chuck 806 is wrapped with an elastic buffer layer. The elastic buffer layer is made of silicone material to avoid surface damage when clamping lens components.

[0057] like Figure 1 As shown, in a preferred embodiment, based on the above method, an annular groove is further provided on the outer side of the top of the mounting base 1, and the limiting ring 3 is embedded in the annular groove. The limiting ring 3 is flush with the outer surface of the mounting base 1. This structure not only makes the installation of the limiting ring 3 more stable and prevents it from moving along the axial direction of the mounting base 1, but also reduces the external protrusion of the mechanism, making the overall appearance smoother. At the same time, it prevents dust and impurities from accumulating in the connection gap between the limiting ring 3 and the mounting base 1, reducing the difficulty of subsequent maintenance.

[0058] Example 3

[0059] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0060] Preliminary angle adjustment stage: Based on the production line layout, workshop space, and the position requirements of adjacent workstations (such as inspection and unloading workstations), the operator rotates the mounting plate 4. Through the rotational cooperation between the limiting ring 3 and the mounting base 1, the angle of the mounting plate 4 and the top linear conveying component 7 is adjusted. During this process, the insertion block 502 of the indicator component 5 slides along the top of the mounting base 1 under the action of the return spring 504. When it is inserted into the corresponding slot 503, the angle is indicated to be aligned. Subsequently, the lifting screw 603 is rotated through the adjustment port 605 of the fixing component 6 to drive the extrusion block 601 to clamp downward, thus fixing the position of the mounting plate 4 and ensuring that the conveying direction of the linear conveying component 7 is adapted to the production requirements, avoiding spatial interference with adjacent mechanisms.

[0061] Workpiece conveying and transfer stage: The linear conveyor assembly 7 is activated, and the first pneumatic chuck 707 descends under the drive of the first vertical cylinder 706 to grab the lens element to be processed. Then, it slides along the first guide groove 702 with the first slider 703 under the drive of the conveyor motor 705 and the conveyor screw 704, conveying the element to the top of the transfer tray 2 and placing it on the top of the transfer tray 2. The drive motor in the mounting base 1 drives the transfer tray 2 to rotate. According to the position of the transfer assembly 8 and the angle of the processing turntable, the orientation of the element on the transfer tray 2 is adjusted so that the element is in the best posture for easy transfer.

[0062] Workpiece transfer and loading completion stage: The translation cylinder 804 of the transfer component 8 drives the second slider 803 to move along the second guide groove 802 towards the transfer plate 2, and the second vertical cylinder 805 drives the second pneumatic chuck 806 to descend and clamp the component; then the second vertical cylinder 805 rises, and the translation cylinder 804 drives the second slider 803 to reset towards the processing turntable. When it reaches the corresponding station above the processing turntable, the second vertical cylinder 805 descends, the second pneumatic chuck 806 releases, and the component is accurately placed into the positioning fixture of the processing turntable, completing one loading process. After that, all components of the mechanism reset and enter the next loading cycle, continuously providing lens components for the multi-station assembly process of the processing turntable. The whole process not only realizes the flexible adjustment of the loading position, but also shortens the conveying stroke through the transfer plate 2, reduces the overall space occupied by the equipment, and adapts to the needs of compact production lines.

[0063] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
