Description

Technical Field

[0001] This invention relates to the field of optical lens laser cutting technology, and in particular to an optical lens positioning and cutting device. Background Technology

[0002] In the mass production of optical lenses, laser cutting technology is often used to cut a single raw material sheet (such as optical glass or resin sheet) into multiple lenses arranged in a matrix to meet the batch demand for optical components. Existing optical lens positioning and cutting devices typically use a laser cutting head to cut along a preset trajectory, resulting in multiple lenses that are separated from each other but have not completely detached from the raw material sheet.

[0003] However, existing equipment has significant shortcomings in the material collection stage after cutting. Specifically, the cut lenses remain embedded in the residual material frame of the raw material plate, requiring manual or auxiliary equipment to manually eject and collect them one by one. Currently, the common practice is for operators to use a handheld vacuum suction cup to pick up dozens or even hundreds of small lenses from the raw material plate one by one, arrange them, and place them into a turnover box.

[0004] This method has the following problems: First, manual operation is inefficient, and the material receiving process becomes the bottleneck of the entire production line; second, the lenses are easily bumped, scratched or contaminated during manual picking, affecting the yield of finished products; third, the lenses after receiving are arranged in a messy manner, making it difficult to achieve smooth docking with subsequent equipment, thus hindering the construction of a fully automated production line.

[0005] Therefore, in order to improve the efficiency of cutting and batch processing, the present invention provides an optical lens positioning and cutting device. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing an optical lens positioning and cutting device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an optical lens positioning and cutting device for cutting raw material plates and collecting lenses in batches, including a frame, a laser cutting head and a clamping mechanism for assisting in separating the raw material plates and lenses, and further including: a functional positioning mechanism disposed on the frame, the functional positioning mechanism including a support plate, a positioning component and a shape switching component.

[0008] The support plate is fixedly installed on the frame, and the support plate has multiple dropping holes adapted to the corresponding lenses; the form switching component is used to drive the positioning component to switch between the cutting state and the receiving state; the positioning component includes multiple support units, each support unit is set with a dropping hole, which is used to support the raw material plate from below in the cutting state and transfer the lens in the receiving state.

[0009] A material collection mechanism is mounted on the frame and includes a stepped conveying assembly and a stacking assembly. The stepped conveying assembly is used to receive lenses falling from the support unit in the receiving state. The stacking assembly is used to collect the lenses on the stepped conveying assembly by stacking them in columns.

[0010] In the aforementioned optical lens positioning and cutting device, a clamping mechanism is movably mounted on the frame and located above the functional positioning mechanism. The clamping mechanism includes a pressure plate that is slidably arranged in the vertical direction. A receiving groove is provided on the bottom wall of the pressure plate, and an ejector frame is slidably connected in the receiving groove.

[0011] In the aforementioned optical lens positioning and cutting device, multiple top blocks are arranged in a matrix on the ejector frame. Each top block corresponds to the middle position of the lens and is used to push the lens downwards to separate the remaining material from the raw material plate during the receiving state.

[0012] In the aforementioned optical lens positioning and cutting device, multiple support units in the same row of the positioning components are fixedly connected by a connecting rod; the length of the connecting rod increases sequentially from back to front, and its left and right ends are detachably engaged with the support plate.

[0013] In the aforementioned optical lens positioning and cutting device, the shape switching component includes mounting boxes symmetrically fixed on the left and right sides of the frame, and each mounting box contains multiple guide plates that correspond one-to-one with the connecting rods.

[0014] In the aforementioned optical lens positioning and cutting device, a vertical slide is provided on the guide plate, and a horizontal slide is slidably connected on the vertical slide, with the end of the connecting rod slidably connected to the horizontal slide.

[0015] In the aforementioned optical lens positioning and cutting device, the material collection mechanism further includes multiple L-shaped clearance grooves formed on the frame. The connecting rod slides through the L-shaped clearance grooves. The horizontal section of the L-shaped clearance groove is adapted to the slide rail of the transverse slide block, and the vertical section is adapted to the vertical slide rail, which is used to provide an avoidance path for the movement of the connecting rod.

[0016] In the aforementioned optical lens positioning and cutting device, the stepped conveying assembly includes multiple sliding supports arranged in a stepped manner, which are slidably connected to the frame in the front-back direction.

[0017] In the aforementioned optical lens positioning and cutting device, the top wall of the sliding support is provided with a positioning groove corresponding to the positioning component. Multiple partitions are fixedly arranged in the positioning groove, which are staggered with the supporting unit, to separate adjacent lenses.

[0018] In the aforementioned optical lens positioning and cutting device, the palletizing assembly includes a collection box movably mounted on the frame. The collection box is a detachable structure and has a partition rack inside.

[0019] Compared with existing technologies, the advantages of this invention are: 1. By cooperating with the functional positioning mechanism and the material collection mechanism, the bottom support function during cutting and the lens transfer and stacking function during material collection are integrated into one unit. The various mechanisms work together, resulting in a compact overall structure, reasonable workflow, and small space occupation. The output lenses are neatly stacked in columns, facilitating automated integration with subsequent processes.

[0020] 2. During the cutting stage, the positioning component supports the raw material plate from below. During the receiving stage, the shape switching component drives the positioning component to slide downwards along the vertical slide, transferring the entire plate of lenses to the stepped conveyor component in one go. Through the sequential backward movement of the sliding support, the lenses are pushed into the stacking component for stacking and collection. The entire receiving process requires no manual intervention, significantly reducing the workload of manually picking and sorting lenses one by one. This achieves automated connection from cutting to receiving, significantly improving the efficiency of mass production. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figures 1 to 3 An optical lens positioning and cutting device is used to cut a raw material plate 3 into multiple target lenses distributed in a matrix, and to collect the cut lenses in batches. The device mainly includes a frame 1, a laser cutting head 2, a clamping mechanism 4, a functional positioning mechanism 5, and a material collection mechanism 6.

[0037] The laser cutting head 2 is driven by a robotic arm to move above the frame 1 and can move along the X and Y directions to perform matrix laser cutting on the raw material plate 3.

[0038] The clamping mechanism 4 is movably mounted on the frame 1 and located above the laser cutting head 2 and the functional positioning mechanism 5, and is used to separate the auxiliary lens from the excess material. All mechanisms work together, resulting in a compact overall structure, a rational workflow, and a small footprint.

[0039] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The functional positioning mechanism 5 is mounted on the frame 1 and is used to support the raw material plate 3 from below in the cutting state and to transfer the cut lens to the collecting mechanism 6 in the receiving state. Specifically, the functional positioning mechanism 5 includes a support plate 51, a positioning element 52, and a shape switching assembly 53.

[0040] The support plate 51 is fixedly mounted on the frame 1, and its top surface is a flat support plane. The support plate 51 has multiple blanking holes (not labeled in the figure) that are adapted to the target lens. These blanking holes are arranged in a preset matrix, and their number and spacing correspond perfectly to the lens array to be cut.

[0041] Reference Figures 5 to 6 The positioning component 52 includes multiple support units 521, each corresponding to a material drop hole. In the cutting state, the upper surface of the support unit 521 is flush with the upper surface of the support plate 51, used to support the raw material plate 3 from below. Multiple support units 521 in the same row (left-right direction) are fixedly connected as one unit by a connecting rod 522. The length of the connecting rod 522 increases sequentially from back to front, that is, the connecting rod 522 on the side closer to the operator (front side) is longer, and the connecting rod 522 on the side farther from the operator (rear side) is shorter. The left and right ends of the connecting rod 522 are detachably engaged with the support plate 51, and can be disengaged and move along a specific trajectory under the drive of the form switching component 53.

[0042] It should be noted that the single-sided gap between the material discharge hole and the support unit 521 should be controlled within the range of 0.02mm to 0.05mm to prevent jamming during shape switching.

[0043] Reference Figure 5 , Figure 7 , Figure 8 and Figure 11 The form switching component 53 is used to drive the positioning component 52 to switch between the cutting state and the receiving state. The form switching component 53 includes mounting boxes 531 symmetrically fixed on the left and right sides of the frame 1. Each mounting box 531 is provided with multiple guide plates 532 that correspond one-to-one with the connecting rods 522.

[0044] Vertical slides 533 are provided on the guide plate 532. The vertical slides 533 on multiple guide plates 532 on the same side have different lengths. The vertical slides 533 on the guide plates 532 are distributed from the inside to the outside (i.e. from the side closer to the frame 1 to the side farther away from the frame 1), and their corresponding bottom ends are stepped down one after another.

[0045] A transverse slide block 534 is slidably connected to the vertical slide rail 533 via an electric slider, and the end of the connecting rod 522 is slidably connected to the transverse slide block 534 via an electric slider. The transverse slide blocks 534 on the multiple guide plates 532 have different lengths, and the transverse slide blocks 534 on the guide plates 532 are distributed from the inside out (i.e. from the side closer to the frame 1 to the side farther away from the frame 1), and their corresponding front ends are stepped and gradually become longer.

[0046] It should be noted that the stepped height difference of the vertical slide rail 533 has been precisely calculated by those skilled in the art to ensure that the endpoint of the downward movement of each row of support units 521 is exactly 0.1mm to 0.2mm higher than the bearing surface of the corresponding sliding bracket 611.

[0047] Reference Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 The collecting mechanism 6 is movably mounted on the frame 1, located below the functional positioning mechanism 5, and is used to receive the lenses falling from the support unit 521 in the receiving state and collect them by stacking them in columns. The collecting mechanism 6 includes a stepped conveying assembly 61 and a palletizing assembly 62.

[0048] The stepped conveying assembly 61 includes multiple sliding supports 611 arranged in a stepped pattern. Driven by an electric slider, the sliding supports 611 are slidably connected to the frame 1 in the front-to-back direction, and their number corresponds to the number of rows of the lens array (i.e., the positioning elements 52). The top wall of each sliding support 611 has a positioning groove 612 corresponding to the positioning element 52, and multiple spacers 613, staggered with the supporting units 521, are fixedly installed in the positioning groove 612. The stepped distribution of the sliding supports 611 is such that the foremost sliding support 611 is the lowest, and the position gradually increases backward, forming an inclined stepped surface to facilitate subsequent row-by-row conveying.

[0049] The palletizing assembly 62 includes a collection box 621 movably mounted on the frame 1. The collection box 621 is a detachable structure, and its interior is provided with a dividing rack 622, which divides the interior of the collection box 621 into multiple independent storage slots, each storage slot corresponding to a row of lenses. The palletizing assembly 62 can slide in the front-to-back direction (driven by a horizontal drive component) and move in the vertical direction (driven by a lifting drive component). During the receiving process, the collection box 621 is always located directly in front of the sliding support 611 currently receiving the lens.

[0050] In addition, the material collection mechanism 6 also includes multiple L-shaped clearance grooves 63 formed on the frame 1. The connecting rod 522 slides through the L-shaped clearance groove 63. The horizontal section of the L-shaped clearance groove 63 is adapted to the slide rail of the transverse slide block 534, and the vertical section is adapted to the vertical slide rail 533, which is used to provide a clearance path for the movement of the connecting rod 522 during the shape switching process.

[0051] It should be noted that the surface hardness of components that directly contact the lens, such as the support unit 521, the positioning groove 612 of the sliding support 611, and the spacer 613, should not be higher than that of the lens material (especially resin lenses). They should be made of polytetrafluoroethylene (PTFE) coating or POM (polyoxymethylene) engineering plastic to prevent scratching the lens.

[0052] Reference Figure 1 , Figure 2 and Figure 4 The clamping mechanism 4 is movably mounted on the frame 1 and located above the functional positioning mechanism 5. The clamping mechanism 4 includes a pressure plate 41 that slides vertically (driven by a lifting drive). The bottom wall of the pressure plate 41 has a receiving groove, in which an ejector frame 42 is slidably connected via a small electric slider.

[0053] The ejector 42 has multiple top blocks (not labeled in the figure) arranged in a matrix. The number and position of the top blocks correspond one-to-one with the center position of the target lens. The top blocks are used to push the lens downward in the receiving state, so that the lens is completely separated from the remaining material on the raw material plate 3.

[0054] It should be noted that the aforementioned horizontal drive component can be driven by a combination of a motor and a lead screw, while the lifting drive component can be driven by a hydraulic cylinder to move up and down.

[0055] The working process of this device is divided into a cutting stage and a receiving stage, as follows: I. Cutting stage: Loading and positioning: The raw material plate 3 is placed on the support plate 51, so that the raw material plate 3 covers all the dropping holes. At this time, the positioning component 52 is in the cutting state: each support unit 521 is located in the corresponding dropping hole, and its upper surface is flush with the upper surface of the support plate 51, supporting the raw material plate 3 from below.

[0056] Laser cutting: The laser cutting head 2 moves according to a preset matrix trajectory to laser cut the raw material plate 3. After cutting, multiple lenses corresponding to the positions of the support unit 521 are formed on the raw material plate 3, but the lenses still maintain their overall shape through uncut micro-connection points or residual material frames.

[0057] II. Material Receiving Stage: Pressing and Preparation: The pressing mechanism 4 is activated, and the pressure plate 41 slides downward in the vertical direction to press the non-lens area of ​​the raw material plate 3 from above, fixing the raw material plate 3 on the support plate 51 and providing reaction force support for subsequent lens separation.

[0058] Form switching: The ejector 42 moves downward, pushing the lens downward through the top block, creating relative motion with the downward-moving lens, thus completely separating the lens from the remaining material on the raw material plate 3. During this process, the form switching component 53 is activated simultaneously, and the horizontal slide 534 slides downward along the vertical slide rail 533, causing the positioning component 52 to slide downward as a whole.

[0059] The horizontal slide block 534 continues to slide downwards along the vertical slide rail 533. Due to the stepped height difference of the vertical slide rail 533, the downward travel of the support units 521 in different rows is different, thereby causing the positioning member 52 to move the lens above it downwards to the corresponding stepped conveying assembly 61 (e.g., Figure 7 Change to Figure 8 At this point, the lens has been completely removed from the discharge hole, is located on the top wall of the corresponding support unit 521, and descends to the conveying station. The positioning component 52 engages with the corresponding positioning groove 612, and the spacer 613 separates adjacent lenses (e.g., Figure 9 Change to Figure 10 Each lens is precisely received and separated in its corresponding position.

[0060] Stepped conveying and stacking: After the positioning element 52 brings the lens to the stepped conveying assembly 61, the stepped conveying assembly 61 is activated, and the positioning element 52 moves backward row by row (i.e., to the side away from the stacking assembly 62). During this process, the transverse slide 534 remains unchanged in its current position on the vertical slide 533, while the positioning element 52 slides backward relative to the transverse slide 534.

[0061] Row-by-row receiving: The palletizing assembly 62 moves to the front of the foremost sliding support 611. The stepped conveying assembly 61 operates sequentially from front to back: the foremost sliding support 611 slides back one station (i.e., the distance of one row), while the sliding supports 611 behind it remain stationary. Utilizing the relative movement between them, the entire row of lenses on the foremost sliding support 611 is pushed into the collection box 621 of the palletizing assembly 62 and falls into the corresponding storage slot of the separator rack 622. Subsequently, the palletizing assembly 62 moves backward to the front of the next sliding support 611, which slides backward, pushing the lenses on it into the next layer of the collection box 621. This process continues until all lenses on all sliding supports 611 have been pushed into the separator rack 622 within the collection box 621 (see reference). Figure 8 Change to Figure 11 ).

[0062] Material Retrieval: After material collection is completed, operators or robotic arms remove the stacked lenses from the separator rack 622 and send them to the next process (such as cleaning or coating). Because the separator rack 622 within the collection box 621 separates and stacks the lenses in columns, the lenses are neatly arranged, facilitating subsequent automated loading. The entire material collection process requires no manual intervention, significantly reducing the workload of manually picking and arranging lenses one by one, achieving automated connection from cutting to material collection, and significantly improving the efficiency of mass production.

[0063] After the material receiving stage is completed, the remaining part of the raw material plate 3 after laser cutting, i.e., the scrap material, is still pressed and fixed above the support plate 51 by the clamping mechanism 4. In order to facilitate subsequent continuous processing operations, the scrap material needs to be removed from the device and cleaned up. Before the cleaning step, each mechanism returns to the initial cutting state position.

[0064] In this embodiment, waste cleaning is achieved through a waste cleaning mechanism (not shown in the figure), preferably an air blowing device, as follows: After the material collection stage is completed and the pressure plate 41 of the pressing mechanism 4 is lifted upward, the remaining material is temporarily in a free state. The nozzle of the air blowing device is aimed at the edge of the remaining material, and the remaining material is blown away from the bearing plate 51 by high-pressure airflow, so that it falls into the waste collection box that is pre-placed on the rear side of the frame 1.
