Description

Technical Field

[0001] This invention relates to the field of lens processing, and more particularly to an automatic material handling machine for lens processing. Background Technology

[0002] In the automated processing of optical lenses, especially after injection molding or preliminary forming, they often need to be temporarily bonded to small iron pieces using an alloy to facilitate positioning and transfer in subsequent processes. Existing technologies commonly use mechanical grippers to grasp, transfer, and spray the lenses. However, in practical applications, existing material handling equipment suffers from the following technical problems: First, lenses are mostly made of resin or glass, requiring high surface precision. Traditional rigid grippers directly contact the lens sidewalls, easily causing scratches and indentations on the lens surface during clamping, and even edge chipping or breakage due to improper clamping force control. Especially after the alloy is melted by spraying hot water, the resin lens softens, making precise clamping force difficult to control, easily causing optical surface deformation and affecting lens quality.

[0003] Secondly, the smooth surface of the lenses, coupled with the water stains after spraying, reduces the coefficient of friction, making it difficult for traditional grippers to hold them stably. This can lead to slippage or skew during transport, affecting production cycle time and yield. Furthermore, existing grippers lack effective positioning and support structures when placing lenses in designated positions, making them susceptible to damage from vibrations or instability.

[0004] In summary, existing lens handling equipment still has significant shortcomings in terms of clamping stability and non-destructive gripping. There is an urgent need for an automatic handling device that can achieve non-destructive clamping and stable transfer to meet the production needs of high-precision lens processing. Summary of the Invention

[0005] To address the aforementioned problems, the present invention provides an automatic material handling machine for lens processing, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solution: The present invention provides an automatic material handling machine for lens processing, comprising a horizontal mechanism, two sets of lifting mechanisms, two sets of gripping mechanisms, and a blowing mechanism. The two sets of lifting mechanisms are symmetrically connected to the control end of the horizontal mechanism; the two sets of gripping mechanisms are connected to the control end of the lifting mechanisms, and the two sets of gripping mechanisms correspond one-to-one with the two sets of lifting mechanisms. The gripping mechanisms are used to grip the lenses; the gripping mechanism includes a gripper feeding base plate installed on the lifting mechanism, and two opposing electric sliders are provided on the gripper feeding base plate. The two electric sliders move synchronously, and a U-shaped base is installed at the lower end of the electric slider. A locking column module is provided on each of the two vertical sections of the U-shaped base; the blowing mechanism is provided on one of the gripping mechanisms and is used to blow airflow to clean the surface of the gripped lens.

[0007] During the lens processing, the automatic material handling machine is used to grab and transfer the lens. In the grabbing and transfer stage, the grabbing mechanism first performs multi-point primary clamping on the circumferential sidewall of the lens, and then continues to perform secondary limiting and fixing on the upper and lower end faces of the lens through the grabbing mechanism.

[0008] According to an advantageous embodiment, the transverse mechanism includes a transverse track, a servo motor drive module, and a mounting plate. The servo motor drive module is fixedly disposed inside the transverse track, and the mounting plate is slidably disposed inside the transverse track. The servo motor drive module and the mounting plate are connected.

[0009] According to an advantageous embodiment, the lifting mechanism includes a gripper lifting cylinder, which is fixed to a mounting plate by a cylinder mounting seat.

[0010] According to an advantageous embodiment, the locking post module includes an externally threaded post that is threadedly connected to the vertical section of the U-shaped base. A hollow sleeve post is fixedly provided at the lower end of the externally threaded post. A limiting groove communicating with the interior of the hollow sleeve post is provided on the side wall of the hollow sleeve post. The limiting groove is provided along the axial direction of the hollow sleeve post. Two rubber sleeves of different lengths are provided on the outer wall of the hollow sleeve post. A strip-shaped groove communicating with the limiting groove on the hollow sleeve post is provided at the position corresponding to the limiting groove on the hollow sleeve post.

[0011] According to an advantageous embodiment, a limiting rod is further provided at the central axis position of the hollow sleeve column. A transfer sleeve is movably sleeved at the lower end of the limiting rod. An annular protrusion is provided at the upper end of the transfer sleeve, and a movable through hole is provided at the upper end of the transfer sleeve. The lower end of the limiting rod is movably disposed inside the movable through hole. A limiting plate is movably connected to the middle part of the transfer sleeve. A primary spring is connected to the outer wall of the rod body between the limiting plate and the annular protrusion of the transfer sleeve. An abutment rod is connected to the lower end of the transfer sleeve. A secondary spring is sleeved on the outer wall of the abutment rod. A threaded end cap is provided at the lower end of the hollow sleeve column, and the abutment rod and the threaded end cap are movably connected. The upper end of the secondary spring is fixedly connected to the abutment rod, and the lower end of the secondary spring is fixedly connected to the threaded end cap.

[0012] According to an advantageous embodiment, a mating block is fixedly provided on the outer wall of the transfer sleeve between the abutment rod and the limiting plate, and a wedge-shaped locking block is slidably provided inside the transfer sleeve corresponding to the mating block. A return spring is connected between the wedge-shaped locking block and the inner wall of the transfer sleeve. A through strip hole is provided in the middle of the wedge-shaped locking block, and a trapezoidal block that mates with the mating block is provided on the side wall of the strip hole.

[0013] According to an advantageous embodiment, the spring constant K of the secondary spring is greater than the spring constant K of the primary spring.

[0014] According to an advantageous embodiment, the blowing mechanism includes an air pump and two symmetrically arranged air nozzles connected to the air pump via air guide pipes.

[0015] Compared with the prior art, the automatic material handling machine for lens processing provided by the embodiments of the present invention has the following beneficial effects: 1. The present invention, through the linkage structure of the clamping column module, the limiting plate, and the wedge-shaped locking block, adds a secondary limiting and fixing of the upper and lower end faces of the lens on the basis of the primary clamping of the lens sidewall; specifically, during the descent of the gripping mechanism, the abutment rod is compressed and retracts, driving the wedge-shaped locking block to retract, so that the upper end face of the lens is pressed by the limiting plate; after clamping, the abutment rod resets, and the wedge-shaped locking block extends and locks the lower end face of the lens, realizing the bidirectional limiting of the lens in both directions; this structure not only effectively prevents the lens from slipping due to the shift of the center of gravity during the transfer process, but also avoids the problem of excessive clamping force or sliding damage caused by the traditional gripper relying only on the friction of the sidewall; at the same time, the rubber sleeve on the outer wall of the clamping column module makes flexible contact with the sidewall of the lens during clamping, further reducing the risk of scratching the lens surface, especially suitable for non-destructive gripping of resin lenses after softening in hot water.

[0016] 2. This invention, through the synergistic action of the limiting plate and the wedge-shaped locking block, ensures that the lens is always clamped during the transfer process. Even if the overall center of gravity of the lens deviates from the center of the lens after it is bonded to the small iron, it can still maintain a stable posture, avoiding falling or bumping due to tilting. In addition, the linkage design of the abutment rod and the wedge-shaped locking block means that the lower limit can only be unlocked by contacting the table surface with the abutment rod before the lens is placed. This ensures that the lens is completely unlocked only when it is placed on the table, avoiding safety hazards caused by premature loosening or misoperation, and significantly improving the reliability and automation of the equipment.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will now be described in further detail.

[0025] Please refer to the following: Figure 1 An automatic material handling machine for lens processing includes a horizontal mechanism 1, two sets of lifting mechanisms 2, two sets of gripping mechanisms 3, and a blowing mechanism 4. The horizontal mechanism 1 is installed on the production line. The two sets of lifting mechanisms 2 are symmetrically connected to the control end of the horizontal mechanism 1, and the two sets of gripping mechanisms 3 are connected to the control end of the lifting mechanisms 2. The two sets of gripping mechanisms 3 correspond one-to-one with the two sets of lifting mechanisms 2. The gripping mechanisms 3 are used to grip the lenses. The blowing mechanism 4 is set on one of the gripping mechanisms 3 and is used to blow airflow to clean the surface of the gripped lenses. It should be noted that the blowing mechanism 4 adopts a common structure, which includes an air pump inside and two symmetrically arranged air nozzles outside. The air nozzles are connected to the air pump through an air guide pipe. When the blowing mechanism 4 is working, the positive pressure blowing and negative pressure suction of the air nozzles are achieved by the forward and reverse rotation of the motor inside the air pump.

[0026] Before operation, in the two sets of gripping mechanisms 3, the one set without the blowing mechanism 4 is moved to directly above the workpiece transfer box on the production line by the horizontal mechanism 1. During operation, when the lens with the small iron attached is transferred to directly above the workpiece transfer box on the production line, the corresponding lifting mechanism 2 drives the corresponding gripping mechanism 3 to descend. Then, the gripping mechanism 3 grabs the lens with the small iron attached and sends it to the spray position of the spray tank. Subsequently, the spray grippers inside the spray tank transfer the lens with the small iron attached to directly below the spray head, and the spray head sprays the lens through the small iron attached to the workpiece transfer box. The lens with the small iron piece attached to it is sprayed with hot water at around 60 degrees Celsius. The hot water melts the alloy, causing the small iron piece and the lens to separate quickly. After that, the horizontal mechanism 1 moves another set of gripping mechanisms 3, which is connected to the blowing mechanism 4, to directly above the lens spraying grippers in the spray tank. Then, the gripping mechanism 3, which is connected to the blowing mechanism 4, grabs the lens after it has separated from the small iron piece, causing the lens to leave the spray tank. Then, the blowing mechanism 4 blows air to quickly dry the water stains on the lens surface. After the lens surface is dry, the horizontal mechanism 1 adjusts the position of the gripping mechanism 3, and the lens is placed in the collection box in conjunction with the gripping mechanism 3.

[0027] See Figure 1 The horizontal mechanism 1 includes a horizontal track 11, a servo motor drive module 12, and a mounting plate 13. The servo motor drive module 12 is fixedly installed inside the horizontal track 11, and the mounting plate 13 is slidably installed inside the horizontal track 11. The servo motor drive module 12 and the mounting plate 13 are connected.

[0028] When the horizontal mechanism 1 is working, the servo motor drives the motor in the module 12 to rotate, which drives the mounting plate 13 to move left and right, thereby achieving precise positioning of the gripping mechanism 3 in the horizontal direction.

[0029] See Figure 1 The lifting mechanism 2 includes a gripper lifting cylinder 21, which is fixed on the mounting plate 13 by a cylinder mounting seat. The gripper lifting cylinder 21 controls the precise positioning of the gripping mechanism 3 in the vertical direction by lifting.

[0030] See Figure 2 The gripping mechanism 3 includes a gripper base plate 31 installed at the end of the gripper lifting cylinder 21. Two electric sliders 32 that move in opposite directions are provided on the gripper base plate 31. The two electric sliders 32 move synchronously. A U-shaped base 33 is installed at the lower end of the electric slider 32. A locking column module 34 is provided on each of the two vertical sections of the U-shaped base 33.

[0031] When gripping the lens using the gripping mechanism 3, the gripper base plate 31 is first moved to directly above the corresponding lens by the transverse mechanism 1 and the gripper lifting cylinder 21. The gripper lifting cylinder 21 continues to move so that the lower end of the clamping column module 34 contacts the workpiece transfer box. Then, the corresponding two electric sliders 32 move synchronously to control the U-shaped base 33 to move closer to each other. The four clamping column modules 34 on the two U-shaped bases 33 move closer to each other to complete the gripping and clamping of the lens. After clamping, the gripper lifting cylinder 21 gradually retracts, and the lower end of the clamping column module 34 disengages from the workpiece transfer box, thus completely clamping and fixing the lens.

[0032] See Figure 3 and Figure 5 The locking post module 34 includes an externally threaded post 341 that is threadedly connected to the vertical section of the U-shaped base 33. A hollow sleeve post 342 is fixedly provided at the lower end of the externally threaded post 341. A limiting groove 343 communicating with the interior of the hollow sleeve post 342 is provided on the side wall of the hollow sleeve post 342. The limiting groove 343 is arranged along the axial direction of the hollow sleeve post 342. Two rubber sleeves 344 of different lengths are provided on the outer wall of the hollow sleeve post 342. A strip-shaped groove 345 communicating with the limiting groove 343 on the hollow sleeve post 342 is provided on the rubber sleeve 344 at the position corresponding to the limiting groove 343 on the hollow sleeve post 342.

[0033] The two U-shaped bases 33 have a total of four clamping modules 34 that are close to each other to complete the first-level clamping of the lens sidewall. It should be noted that when clamping the lens, the rubber sleeve 344 on the outer wall of the hollow sleeve 342 contacts the lens sidewall. The rubber sleeve 344 in contact with the lens sidewall plays a protective role, preventing the hollow sleeve 342 from causing scratches or damage to the lens sidewall during the clamping and transportation process.

[0034] To better limit the position of the clamped lens, ensure its stability during transport, and prevent lens tilting due to the overall center of gravity being off-center from the lens's center, please refer to [reference needed]. Figure 4 and Figure 6A limiting rod 346 is also provided at the central axis position of the hollow sleeve column 342. A transfer sleeve 347 is movably sleeved at the lower end of the limiting rod 346. An annular protrusion 348 is provided at the upper end of the transfer sleeve 347, and a movable through hole 349 is provided at the upper end of the transfer sleeve 347. The lower end of the limiting rod 346 is movably disposed inside the movable through hole 349. A limiting plate 350 is movably connected to the middle of the transfer sleeve 347. A primary spring 351 is connected to the outer wall of the rod body between the limiting plate 350 and the annular protrusion 348 of the transfer sleeve 347. An abutment rod 352 is connected to the lower end of the transfer sleeve 347. A secondary spring 353 is sleeved on the outer wall of the abutment rod 352. A threaded end cap 354 is provided at the lower end of the hollow sleeve column 342, and the abutment rod 352 and the threaded end cap 354 are movably connected. The upper end of the secondary spring 353 is fixedly connected to the abutment rod 352, and the lower end of the secondary spring 353 is fixedly connected to the threaded end cap 354. A mating block 355 is fixedly provided on the outer wall of the transfer sleeve 347 located between the abutment rod 352 and the limiting plate 350. A wedge-shaped locking block 356 is slidably provided inside the transfer sleeve 347 corresponding to the mating block 355. A return spring 357 is connected between the wedge-shaped locking block 356 and the inner wall of the transfer sleeve 347. A through strip hole 359 is provided in the middle of the wedge-shaped locking block 356. A trapezoidal block 358 that mates with the mating block 355 is provided on the side wall of the strip hole 359. The elastic stiffness coefficient K of the secondary spring 353 is greater than that of the primary spring 351. The purpose is to ensure that the abutment rod 352 can always remain in its original position under the tension of the secondary spring 353.

[0035] Specifically, when the gripper lifting cylinder 21 moves to bring the lower end of the clamping column module 34 into contact with the workpiece transfer box, the contact rod 352 is first gradually compressed into the hollow sleeve column 342. During the compression of the contact rod 352, the mating block 355 and the trapezoidal block 358 cooperate, causing the part of the wedge-shaped locking block 356 exposed in the hollow sleeve column 342 to be completely retracted into the limiting groove 343. The upper edge of the lens is limited by the limiting plate 350. As the gripper lifting cylinder 21 continues to extend, the lens's contact causes the limiting plate 350 to slide upward along the limiting groove 343. During the upward sliding of the limiting plate 350, it is guided and limited by the transfer sleeve rod 347. During the upward sliding of the limiting plate 350 along the limiting groove 343, the primary spring 351 is gradually compressed, while the secondary spring 353 is gradually stretched. As the lower end of the lens is positioned above the wedge-shaped locking block 356, the U-shaped base 33 moves closer to each other via the synchronous movement of the two corresponding electric sliders 32. The four locking pin modules 34 on the two U-shaped bases 33 move closer to each other to complete the lens gripping and clamping operation. Then, the gripper lifting cylinder 21 gradually retracts. During the retraction of the gripper lifting cylinder 21, the compressed primary spring 351 gradually resets, and the stretched secondary spring 353 also gradually resets. At this time, the contact rod 352 gradually resets. During its reset, the mating block 355 gradually disengages from the trapezoidal block 358. Simultaneously, the end of the wedge-shaped locking block 356 gradually extends out of the strip-shaped through groove 345. At this time, the lens is completely positioned between the limiting plate 350 and the wedge-shaped locking block 356. The upper and lower end faces of the lens are fixed by the limiting plate 350 and the wedge-shaped locking block 356 in a two-stage limiting manner.

[0036] After the lens is transferred to the designated position, the gripper lifting cylinder 21 extends, causing the lower end of the abutment rod 352 to contact the ground. This causes the wedge-shaped locking block 356 to retract. Finally, the electric slider 32 moves to separate the hollow sleeve 342 from the side wall of the lens, thus releasing the lens. It should be noted that after the lens is transferred to the designated position, there is a certain height difference between the ground contacted by the abutment rod 352 and the platform on which the lens is placed. This step effectively ensures that the placed lens remains stable. At the same time, the abutment rod 352 plays a positioning role. During the process of the abutment rod 352 contacting the ground and pressing, all the wedge-shaped locking blocks 356 retract synchronously, thus ensuring the stability of the lens.

[0037] The combined action of the limiting plate 350 and the wedge-shaped locking block 356 effectively solves the problem of eccentric detachment during lens transfer. At the same time, the wedge-shaped locking block 356 is linked with the abutment rod 352. The extension and retraction of the abutment rod 352 controls the retraction of the wedge-shaped locking block 356. Thus, the wedge-shaped locking block 356 limits and clamps the upper and lower end faces of the lens during lens transfer, effectively solving the problem of lens slippage caused by sliding between the lens and the hollow sleeve 342 during the transfer process after clamping the side wall of the lens with a traditional single hollow sleeve 342.

[0038] This automatic feeding machine is used to complete a series of automated operations such as gripping, transferring and drying in lens processing. Its specific workflow is as follows: Step 1: Initial gripping (including the feeding of alloy lenses).

[0039] After the equipment is started, the servo motor in the horizontal mechanism 1 drives the module 12 to work, causing the mounting plate 13 to slide on the horizontal track 11, precisely positioning the gripping mechanism 3 (without the blowing mechanism 4) directly above the workpiece transfer box on the production line. When the lens carrying the alloy small iron reaches the designated position on the production line, the corresponding lifting mechanism 2 is activated, causing the gripping mechanism 3 to descend.

[0040] During the descent, the clamping column module 34 at the bottom of the gripping mechanism 3 first contacts the workpiece transfer box. At this time, the four clamping column modules 34 are driven to clamp the lens from the side wall by the opposite movement of the two electric sliders 32. After clamping is completed, the gripper lifting cylinder 21 retracts, removing the lens from the transfer box.

[0041] Step 2: Spray separation (alloy melting).

[0042] The gripping mechanism 3 carries the lens to the spray position in the spray tank via the transverse mechanism 1. After the gripping mechanism 3 delivers the lens, a dedicated spray gripper inside the spray tank transfers the lens to directly below the spray head. Subsequently, the spray head activates, spraying hot water at approximately 60 degrees Celsius onto the lens. The purpose of the hot water spray is to melt the alloy connecting the lens and the small iron piece, thereby achieving rapid and non-destructive separation of the lens and the small iron piece.

[0043] Step 3: Drying treatment (water stain removal).

[0044] After the lens is separated from the small iron piece, the horizontal mechanism 1 operates again, moving another set of gripping mechanisms 3, equipped with a blowing mechanism 4, directly above the lens spray grippers inside the spray tank. The gripping mechanism 3 descends, removing the separated lens from the spray grippers and taking it out of the spray tank. Subsequently, the blowing mechanism 4 activates, blowing airflow through the nozzle cover onto the lens surface to quickly remove residual water stains and dry the lens.

[0045] Step 4: Lens transfer and stable placement.

[0046] After drying, the horizontal mechanism 1 adjusts the position of the gripping mechanism 3 according to the preset program, preparing to place the lens into the collection box. During the transfer process, in order to ensure the stability of the lens and prevent it from falling off due to the shift of the center of gravity, the internal mechanism of the locking module 34 will work in conjunction: the limiting plate 350 presses the upper end face of the lens, while the wedge-shaped locking block 356 extends under the action of the spring and locks the lower end face of the lens, realizing the two-level limiting and fixing of the upper and lower ends of the lens.

[0047] When the lens reaches the designated position in the collection box, the gripper lifting cylinder 21 extends again, causing the lower end of the contact rod 352 to contact the placement platform. The contact rod 352 contracts under pressure, causing the wedge-shaped locking block 356 to retract synchronously, releasing the lock on the lower end face of the lens. Finally, the electric slider 32 moves in the opposite direction, causing the four locking pin modules 34 to release the side wall of the lens, and the lens falls smoothly into the collection box, completing the entire automatic material handling and processing process.
