Description

Technical Field

[0001] This invention belongs to the field of optical lens cleaning technology, and specifically relates to a lens surface cleaning device. Background Technology

[0002] Lenses are used in various fields of existing technology. During the lens production process, optical spherical lenses will have oil stains left on the lens surface during the coating process, and manual tray placement will generate dust. Finished lenses need to have the oil stains and dust removed from their surfaces before they can be shipped. The current mature method for removing oil stains is to manually wipe the lens surface with a lint-free cloth and manually arrange the lenses in trays and boxes to meet the shipping standards. However, due to the high cleanliness requirements of lenses, the material cost is high, and the manual cleaning of the surface involves contact with the lens during wiping and tray placement, causing secondary contamination. Furthermore, the application of lint-free cloths is not easy to control precisely, resulting in high consumable consumption, low product yield, low cleaning efficiency, and high labor costs. For example, currently, one person can only wipe about 2,000 lenses per day (based on 8 hours), and manual wiping requires tray placement, which is not conducive to automated assembly line production and flexible docking and adjustment with other process equipment. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by proposing a lens surface cleaning device that has high lens cleaning efficiency, high product yield, and helps to reduce labor costs, consumable costs, and time costs.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] This invention proposes a lens surface cleaning device, comprising a feeding mechanism, a lens cleaning mechanism, and a discharging mechanism, wherein:

[0006] The feeding mechanism is used to convey the lens carrier plate to the lens cleaning mechanism. Several lenses are placed on the lens carrier plate.

[0007] The lens cleaning mechanism includes a second frame and a material transfer platform, a conveying unit, a rotating platform, a cleaning unit, and a alignment unit, all connected to the second frame, wherein:

[0008] The material transfer platform connects to the loading mechanism, handling unit, and unloading mechanism, and is used for the transfer of lens carrier plates.

When feeding, the first linear motion unit drives the hook plate to move along the conveying direction of the first synchronous belt conveying unit and guides it through the first guide unit. The hook plate hooks the lens carrier plate in the first chute on the first hopper to the first synchronous belt conveying unit, and then the first synchronous belt conveying unit conveys the lens carrier plate to the material transfer platform to complete the unloading.

[0016] The unloading and conveying unit includes a fifth mounting base, a second synchronous belt conveying unit, and a check valve unit. The fifth mounting base is connected to the third frame, and the second synchronous belt conveying unit is connected to the fifth mounting base. The check valve unit includes a third linear motion unit, a third guide unit, and an elastic limiting unit. The third linear motion unit and the third guide unit are both connected to the fifth mounting base. The elastic limiting unit includes a connecting seat, a top block, and a spring. The top block is rotatably connected to the connecting seat, and the two ends of the spring abut against the top block and the connecting seat, respectively. When unloading, the second synchronous belt conveying unit conveys the lens carrier plate on the material transfer platform toward the second hopper. Under the gravity of the lens carrier plate, the top block automatically presses down and flips, and automatically pops out and resets after the lens carrier plate has been conveyed. Then, the third linear motion unit drives the connecting seat to move along the conveying direction of the second synchronous belt conveying unit and guides it through the third guide unit. The lens carrier plate is hooked and sent to the corresponding first chute on the second hopper by the automatically popped-out and reset top block to complete the loading.

[0017] Preferably, both the first lifting unit and the second lifting unit include a second mounting base, a third mounting base, a fourth mounting base, and a second linear motion unit.

The first motor is connected to the fourth mounting base. The two ends of the lead screw of the first lead screw and nut mechanism are respectively connected to the second mounting base and the fourth mounting base. The nut of the first lead screw and nut mechanism is connected to the third mounting base. The first motor drives the first transmission mechanism to drive the first lead screw and nut mechanism to move and is guided by the second guide unit, thereby driving the third mounting base to move along the Z-axis to realize the lifting and lowering of the corresponding hopper.

[0018] Preferably, the material transfer platform includes a carrier plate conveying unit and a carrier plate positioning unit. The carrier plate conveying unit includes a transfer platform frame and a third synchronous belt conveying unit.

The first cylinder is connected to the sixth mounting seat and is used to drive the seventh mounting seat to move along the Z-axis. When the lens carrier is conveyed to the carrier conveying unit, the second cylinder drives the first stop block to rise and block and limit the lens carrier that has moved to the top of the carrier positioning unit. Then, the first cylinder drives the limiting boss to rise and position the lens carrier to dock with the conveying unit. After the lens on the lens carrier is wiped, the first cylinder drives the limiting boss to fall, and the second cylinder drives the first stop block to fall, releasing the lens carrier so that the lens carrier is conveyed to the feeding mechanism.

The suction cup is used to pick up lenses from the material transfer platform or the rotating platform.

[0020] Preferably, each adsorption unit is arranged side by side, including a twelfth mounting base, a second transmission mechanism, at least one fixed base and at least one suction rod. The twelfth mounting base is connected to the eleventh mounting base. The second transmission mechanism and the fixed base are both connected to the twelfth mounting base.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1) This device includes a loading mechanism, a lens cleaning mechanism, and a unloading mechanism. The lens cleaning mechanism includes a second frame, a material transfer platform, a handling unit, a rotating platform, a cleaning unit, and a alignment unit. The entire machine has high lens cleaning efficiency and high product yield, and helps reduce labor costs, consumable costs, and time costs. Specifically, the loading and unloading mechanisms can operate independently, enabling the stacking of a large number of lens carriers at once. The loading or unloading function is achieved through the linkage of corresponding hoppers and conveying units. Lenses before and after wiping no longer require manual tray placement, and the speed is faster. For example, 1000 lenses can be loaded at once. The material transfer platform connects with the loading mechanism, handling unit, and unloading mechanism to load the lenses. The plate is conveyed to the corresponding workstation. The material transfer platform and rotating platform are connected by the handling unit to transfer the lens to the corresponding workstation. The alignment unit is connected to the rotating platform to align the lens to avoid eccentric slippage and ensure uniform force during wiping. The decontamination unit is connected to the rotating platform to wipe the lens. The rotating platform can rotate to allow multiple workstations to be connected at the same time, which can realize the quick exchange between the wiping workstation and the material handling workstation. It can complete the functions of automatic loading and unloading of lenses, dripping, wiping and other functions. It is easy to operate, highly automated, and has high decontamination efficiency (compared to manual operation, this device cleans one lens in an average of 5 seconds, and can complete 5700 lenses in 8 hours). It reduces labor costs, avoids direct contact between humans and lenses, and has a high lens production yield.

[0027] 2) The conveying unit and rotating platform adopt vacuum adsorption, which helps to fix the lens without affecting the wiping effect and product quality. The alignment unit helps to solve the lens eccentricity problem, and the decontamination unit can ensure flexible contact with the lens to avoid damaging the lens. In particular, through the extensibility of the material tape itself and the buffering effect of the wiping unit, the material tape can better fit the lens. Even if the material tape is slowly moved away and the fit changes, it can always maintain a close fit with the lens. This solves the problem of uneven force causing incomplete cleaning and avoids lens damage, greatly improving the lens yield. In addition, the material tape and cleaning liquid are fed in a quantitative manner for each wipe, avoiding waste of cleanroom cloth and cleaning liquid, reducing consumables, and thus reducing production costs.

[0028] 3) This device features flexible production capabilities, adapting to product changes and facilitating the universality of different products. The feeding mechanism, unloading mechanism, and lens cleaning mechanism are separated to allow for the addition of other process equipment. For example, if baking or flipping processes are required for different products, the corresponding process equipment can be connected to the feeding mechanism, unloading mechanism, and lens cleaning mechanism.

Detailed Implementation

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may be an intervening component. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application.

[0056] like Figure 1-24 As shown, a lens surface cleaning device includes a feeding mechanism 1, a lens cleaning mechanism 2, and a discharging mechanism 3, wherein:

[0057] The feeding mechanism 1 is used to convey the lens carrier plate 4 to the lens cleaning mechanism 2. Several lenses 5 are placed on the lens carrier plate 4.

[0058] The lens cleaning mechanism 2 includes a second frame 21 and a material transfer platform 22, a conveying unit 23, a rotating platform 24, a cleaning unit 26, and a straightening unit 25, all connected to the second frame 21, wherein:

[0059] The material transfer platform 22 connects to the loading mechanism 1, the handling unit 23 and the unloading mechanism 3, and is used to transfer the lens carrier plate 4.

[0060] The conveying unit 23 is used to transfer the lens 5 to be wiped on the material transfer platform 22 to the rotating platform 24 or to put the lens 5 that has been wiped on the rotating platform 24 back into the lens carrier plate 4 on the material transfer platform 22.

[0061] The rotating platform 24 includes a cam divider 241, an eleventh mounting base 242, two adsorption units 243, and an air pipe connection unit 244. The eleventh mounting base 242 is connected to the second frame 21. The cam divider 241, the adsorption units 243, and the air pipe connection unit 244 are all connected to the eleventh mounting base 242. The cam divider 241 is used to drive the eleventh mounting base 242 to rotate, so that the two adsorption units 243 are respectively connected to the conveying unit 23 and the decontamination unit 26. The adsorption units 243 are used to adsorb at least one lens 5 at the same time. The air pipe connection unit 244 is used to supply air to each adsorption unit 243.

[0062] The number of lenses 5 on the adsorption unit 243 corresponds one-to-one with the number of lenses 5 on the adsorption unit 243, and is used to correct the lenses 5 on the adsorption unit 243 of the docking and transporting unit 23.

[0063] The cleaning unit 26 includes a fourth linear motion unit 261 and at least one tape winding unit 262. The fourth linear motion unit 261 is connected to the second frame 21 and is used to drive each tape winding unit 262 to move horizontally, so as to achieve synchronous wiping of the corresponding lens 5 on the adsorption unit 243. The tape winding unit 262 includes a fourteenth mounting base 262a, a first reel 262b, a second reel 262c, a second motor 262d, a tape 262e, a tape feeding unit 262h, a wiping unit 262i, a first tape clamping unit 262k, a second tape clamping unit 262m, and a plurality of first rollers 262j. The fourteenth mounting base 262a is connected to the fourth linear motion unit 261, and the first reel 262b and the second reel 262c are both connected to the fourteenth mounting base 262a. The two ends of the material strip 262e are respectively wrapped around the first rollers 262j and wound onto the first reel 262b and the second reel 262c. The second motor 262d is used to drive the second reel 262c to rotate and rewind the material strip 262e. The material strip feeding unit 262h is used to unwind the material strip 262e on the first reel 262b. The wiping unit 262i, the first rollers 262j, the first material strip clamping unit 262k, and the second material strip clamping unit 262m are all connected to the fourteenth mounting base 262a. The wiping unit 262i is used to wipe the lens 5 against the material strip 262e or to move away from the material strip 262e to loosen it. The first material strip clamping unit 262k and the second material strip clamping unit 262m clamp the material strip 262e on both sides of the wiping unit 262i to prevent loosening.

[0064] The unloading mechanism 3 is used to convey and collect the lens carrier plate 4 that has been wiped on the material transfer platform 22.

[0065] The lens surface cleaning device connects the feeding mechanism 1, the lens cleaning mechanism 2, and the unloading mechanism 3 to form a fully automated production line. Each electrical component can be automated through microcontroller or PLC programming control. The lens carrier plate 4 can be of any shape, such as a flat plate with multiple grooves, each groove holding a lens tray. Several lenses can be placed on the tray, allowing operators to directly place the entire tray onto the carrier plate 4, avoiding frequent handling of individual lenses and facilitating boxing and packaging after unloading, making operation more convenient. Alternatively, the carrier plate 4 can have several grooves directly formed to accommodate lenses. The conveyor belt 262e can be a cleanroom cloth.

[0066] The lens cleaning mechanism 2 includes a second frame 21, a material transfer platform 22, a handling unit 23, a rotating platform 24, a cleaning unit 26, and a centering unit 25. The second frame 21 has a box structure, which helps to maintain a clean space. A touch screen can also be installed on it as a control panel to facilitate human-machine interaction. It can also be used to install an air pump to supply air to the whole machine. The bottom wall can be equipped with leveling feet and rollers to facilitate handling and leveling to ensure stability. The lens carrier plate 4 is transported to the corresponding workstation by connecting the material transfer platform 22 to the loading mechanism 1, the conveying unit 23, and the unloading mechanism 3. The lens 5 is transferred to the corresponding workstation by connecting the material transfer platform 22 and the rotating platform 24 by the conveying unit 23. The lens 5 is aligned by connecting the alignment unit 25 to the rotating platform 24. The lens 5 is wiped by connecting the decontamination unit 26 to the rotating platform 24. The adsorption unit 243 is rotated 360° by the rotating platform 24. In other words, the cam divider 241 is used to achieve simultaneous docking of multiple workstations. The cam divider 241 has two working stations, which can realize the rapid interchange between the wiping station and the material handling station. The working cycle of the cam divider 241 is affected by the loading and unloading of the conveying unit 23, such as 15 seconds. The dual-station cam divider 241 drives the adsorption unit 243 to rotate 180° each time. One of the two adsorption units 243 is preferably divided into multiple wiping stations, and the other is preferably divided into multiple pick-and-place stations. If both are two, then the two pick-and-place stations correspond to two alignment units 25, meaning each alignment unit 25 is used to align the lens 5 at one pick-and-place station. The wiping stations are used to remove oil stains from the surface of the lens 5. The pick-and-place stations are used to transport the lens 5 to be wiped from the material transfer platform 22 to the rotating platform 24 for pick-up and to return the wiped lens 5 from the rotating platform 24 back to the material transfer platform 22 for unloading. Wiping and decontamination, as well as the pick-and-place process, can be performed simultaneously, resulting in a fast pace and high efficiency. Since the rotating platform 24 itself needs to rotate and the lens 5 needs to be continuously adsorbed during the rotation, the air tube connection unit 244 adopts a slip ring structure and is connected to each adsorption unit 243 through a rotary joint. It is also possible to increase the rotation drive of the lens 5 itself to cooperate with the decontamination unit 26 to achieve uniform wiping.

[0067] The tape 262e of the cleaning unit 26 is wound up by the second reel 262c after passing around each of the first rollers 262j in sequence from the first reel 262b. The first reel 262b unwinds the tape 262e (i.e., the clean tape before use), and the second reel 262c winds up the tape 262e (i.e., the dirty tape after use). It should be noted that those skilled in the art can also reuse the tape 262e on the reverse side after using one side, such as by swapping the position of the second reel 262c after winding and the first reel 262b after unwinding. When wiping, the clean side of the tape 262e should face the lens 5. The first reel 262b, the second strip clamping unit 262m, the wiping unit 262i, the first strip clamping unit 262k, the strip feeding unit 262h, and the second reel 262c are arranged sequentially along the winding direction of the strip 262e on each of the first rollers 262j. The strip feeding unit 262h is used to feed and unwind the strip 262e on the first reel 262b. The wiping unit 262i is used to wipe the lens 5 against the strip 262e to remove surface oil or to loosen the strip 262e. The first strip clamping unit 262k and the second strip clamping unit 262m tighten the strip 262e, and the wiping unit 262i makes the strip 262e fit the lens 5 more evenly. During wiping, the lens 5 can rotate around the optical axis, while the fourth linear motion unit 261 drives each tape winding unit 262 to move horizontally until all the tapes are removed from the lens 5. This is equivalent to the tape 262e rotating and wiping to finally scrape the dirt off the lens 5 to achieve a cleaning effect, thus realizing synchronous wiping of the corresponding lens 5 on the adsorption unit 243. After wiping each lens 5, the tape 262e will be fed once through the tape feeding unit 262h until the tape 262e on the entire first reel 262b is used up and replaced.

[0068] It should be noted that the decontamination unit 26 can also be equipped with a tape breakage detection unit, such as a distance sensor, and set between the first reel 262b and the second tape clamping unit 262m. If the cleanroom cloth on the first reel 262b is used up, the tape breakage detection unit will detect that there is no cleanroom cloth and will sound an alarm to remind the operator to replace the tape 262e.

[0069] In one embodiment, the feeding mechanism 1 includes a first frame 11, a first hopper 12, a feeding conveying unit 13, and a first lifting unit 14. The unloading mechanism 3 includes a third frame 31, a second hopper 32, an unloading conveying unit 33, and a second lifting unit. The feeding conveying unit 13 and the first lifting unit 14 are both connected to the first frame 11. The first hopper 12 and the second hopper 32 each include a frame 121 and a plurality of first chutes 122. The first chutes 122 are arranged side by side along the Z-axis on the frame 121 and are used to mount the lens carrier plate 4. The first lifting unit 14 also includes... The first material hopper 12 is used to drive the first material hopper 12 to move along the Z-axis to connect with the loading conveyor unit 13. The loading conveyor unit 13 is used to convey the lens carrier plate 4 in the first slide 122 on the first material hopper 12 to the material transfer platform 22. The unloading conveyor unit 33 and the second lifting unit are both connected to the third frame 31. The second lifting unit is also used to drive the second material hopper 32 to move along the Z-axis to connect with the unloading conveyor unit 33. The unloading conveyor unit 33 is used to convey the lens carrier plate 4 that has been wiped with the lens 5 on the material transfer platform 22 to the first slide 122 on the second material hopper 32.

[0070] Both the first frame 11 and the third frame 31 are box-like structures, which help keep the lenses 5 in a clean space during wiping. The first hopper 12 and the second hopper 32 have the same or similar structures. For example, each hopper can have ten layers of first chute 122 arranged side by side along the Z-axis, which can accommodate 10 lens carrier plates 4. The specific number of layers is not limited, or other hopper mechanisms commonly used in existing technologies can be used. The loading mechanism 1 and the unloading mechanism 3 can operate independently without affecting the working cycle. Loading or unloading is achieved through the linkage of the corresponding hoppers and conveying units. Moreover, the wiped lenses 5 no longer need to be manually placed on trays, which is faster, more flexible, and facilitates the insertion of other process machines for corresponding operations between the loading mechanism 1, the lens cleaning mechanism 2, and the unloading mechanism 3.

[0071] In one embodiment, the feeding and conveying unit 13 includes a first mounting base 131, a first synchronous belt conveying unit 132, and a hooking unit 133. The first mounting base 131 is connected to the first frame 11, and the first synchronous belt conveying unit 132 is connected to the first mounting base 131. The hooking unit 133 includes a first linear motion unit 133a, a first guide unit 133b, and a hook plate 133c. The first linear motion unit 133a and the first guide unit 133b are both connected to the first mounting base 131. When feeding, the first linear motion unit 133a drives the hook plate 133c to move along the conveying direction of the first synchronous belt conveying unit 132 and guides it through the first guide unit 133b. The hook plate 133c hooks the lens carrier plate 4 in the first chute 122 on the first hopper 12 to the first synchronous belt conveying unit 132, and then the first synchronous belt conveying unit 132 conveys the lens carrier plate 4 to the material transfer platform 22 to complete the unloading.

[0072] The feeding and conveying unit 33 includes a fifth mounting base 331, a second synchronous belt conveying unit 332, and a check unit 333. The fifth mounting base 331 is connected to the third frame 31, and the second synchronous belt conveying unit 332 is connected to the fifth mounting base 331. The check unit 333 includes a third linear motion unit 333a, a third guide unit 333b, and an elastic limiting unit 333c. The third linear motion unit 333a and the third guide unit 333b are both connected to the fifth mounting base 331. The elastic limiting unit 333c includes a connecting seat, a top block, and a spring. The top block is rotatably connected to the connecting seat, and the spring... The two ends of the spring abut against the top block and the connecting seat respectively. When the material is unloaded, the second synchronous belt conveying unit 332 conveys the lens carrier plate 4 on the material transfer platform 22 toward the second hopper 32. The top block automatically presses down and flips under the gravity of the lens carrier plate 4 and automatically pops out and resets after the lens carrier plate 4 is conveyed. Then, the connecting seat is driven by the third linear motion unit 333a to move along the conveying direction of the second synchronous belt conveying unit 332 and is guided by the third guide unit 333b. The lens carrier plate 4 is hooked by the top block after it is automatically popped out and reset and sent to the corresponding first chute 122 on the second hopper 32 to complete the loading.

[0073] In this design, to avoid the hook plate 133c or the elastic limiting unit 333c, the bottom of each layer of the first chute 122 on the corresponding hopper is hollowed out. The first linear motion unit 133a and the third linear motion unit 333a can be pen-shaped cylinders, which have a small space and long stroke, or other linear motion units commonly used in the prior art can be used. The hook plate 133c can be of any shape, such as including a first flat plate and a second stop block connected vertically. When it is necessary to hook the lens carrier plate 4 onto the first synchronous belt conveyor unit 132, the first linear motion unit 133a drives the hook plate 133c to extend into the lens carrier plate 4 below the corresponding first chute 122. Then, the first lifting unit 14 drives the first hopper 12 to descend so that the lens carrier plate 4 falls onto the first flat plate. Then, the first linear motion unit 133a drives the hook plate 133c to retract, and the lens carrier plate 4 is hooked onto the first synchronous belt conveyor unit 132 by the blocking action of the second stop block. When the lens carrier plate 4, after the lens 5 has been wiped, needs to be hooked and sent to the second hopper 32, the second synchronous belt conveyor unit 332 first conveys the lens carrier plate 4 towards the second hopper 32. The top block automatically presses down and flips under the gravity of the lens carrier plate 4 and automatically pops out and resets after the lens carrier plate 4 has been conveyed. Then, the third linear motion unit 333a drives the elastic limiting unit 333c to move, and at the same time, the second lifting unit drives the second hopper 32 to rise, so that the lens carrier plate 4 is hooked and sent to the second hopper 32 into the corresponding first chute 122 by the top block after it has been automatically popped out and reset.

[0074] In one embodiment, both the first lifting unit 14 and the second lifting unit include a second mounting base 141, a third mounting base 142, a fourth mounting base 143, and a second linear motion unit 144. The second mounting base 141 and the fourth mounting base 143 are both connected to the corresponding frame. The second linear motion unit 144 includes a first motor 144a, a first transmission mechanism 144b, at least one first lead screw and nut mechanism 144c, and at least one second guide unit 144d. The first motor 144a is connected to the fourth mounting base 143. The two ends of the lead screw of the first lead screw and nut mechanism 144c are respectively connected to the second mounting base 141 and the fourth mounting base 143. The nut of the first lead screw and nut mechanism 144c is connected to the third mounting base 142. The first motor 144a drives the first transmission mechanism 144b to drive the first lead screw and nut mechanism 144c to move and be guided by the second guide unit 144d, thereby driving the third mounting base 142 to move along the Z-axis to realize the lifting and lowering of the corresponding hopper.

[0075] The first transmission mechanism 144b is a synchronous belt drive mechanism, a rack and pinion drive mechanism, or other common transmission mechanisms in the prior art. In this embodiment, if the first transmission mechanism 144b is a synchronous belt drive mechanism, the first lifting unit 14 and the second lifting unit may further include at least one first tensioning mechanism 144e. The first tensioning mechanism 144e is used to tension the synchronous belt on the first transmission mechanism 144b. If there are two, the specific number can be adjusted according to actual needs. The tensioning mechanism is a common structure in the prior art and will not be described in detail here. The second linear motion unit 144 can also be replaced with other common linear motion units in the prior art, used to drive the third mounting base 142 to move along the Z-axis to achieve the lifting and lowering of the corresponding hopper.

[0076] In one embodiment, the material transfer platform 22 includes a carrier plate conveying unit 221 and a carrier plate positioning unit 222. The carrier plate conveying unit 221 includes a transfer platform frame 221a and a third synchronous belt conveying unit 221b. The transfer platform frame 221a is connected to the second frame 21, and the third synchronous belt conveying unit 221b is connected to the transfer platform frame 221a. It is used to convey the lens carrier plate 4 conveyed by the loading mechanism 1 to above the carrier plate positioning unit 222 or to convey the lens carrier plate 4 after wiping the lens 5 to the unloading mechanism 3. The plate positioning unit 222 includes a sixth mounting base 222a, a seventh mounting base 222b, an eighth mounting base 222c, a first cylinder 222d, a fourth guide unit 222e, a second cylinder 222f, a first stop block 222g, and at least one limiting boss 222h. The seventh mounting base 222b, the sixth mounting base 222a, and the eighth mounting base 222c are arranged side by side, and the sixth mounting base 222a is connected to the transfer platform frame 221a. The fourth guide unit 222e includes at least one guide rod and at least one guide rod sleeve. Both ends are connected to the seventh mounting base 222b and the eighth mounting base 222c respectively. The guide rod sleeve is connected to the sixth mounting base 222a. The guide rod and the guide rod sleeve are slidably connected in a one-to-one correspondence. The limiting boss 222h is set above the eighth mounting base 222c. The second cylinder 222f is connected to the sixth mounting base 222a and is used to drive the first stop block 222g to move along the Z-axis. The first cylinder 222d is connected to the sixth mounting base 222a and is used to drive the seventh mounting base 222b to move along the Z-axis. When the lens carrier plate 4 is conveyed to the carrier plate conveying unit 2 At 21:00, the second cylinder 222f drives the first stop block 222g to rise and block the lens carrier plate 4 that has moved above the carrier plate positioning unit 222. Then, the first cylinder 222d drives the limiting boss 222h to rise and position the lens carrier plate 4 to connect with the conveying unit 23. After the lens 5 on the lens carrier plate 4 is wiped, the first cylinder 222d drives the limiting boss 222h to fall, and the second cylinder 222f drives the first stop block 222g to fall, releasing the lens carrier plate 4 so that the lens carrier plate 4 can be conveyed to the feeding mechanism 3.

[0077] The carrier plate conveying unit 221 and the carrier plate positioning unit 222 facilitate the accurate placement and removal of the lens 5 by the transport unit 23 after the lens carrier plate 4 is positioned, as well as the docking of the loading mechanism 1 and the unloading mechanism 3. The carrier plate positioning unit 222 also includes at least one limiting post 222i, which is vertically arranged on the seventh mounting base 222b and located between the sixth mounting base 222a and the seventh mounting base 222b, for achieving hard limiting.

[0078] In one embodiment, the conveying unit 23 includes a horizontal motion mechanism 231 and a lens adsorption mechanism 232. The horizontal motion mechanism 231 is connected to the second frame 21 and is used to drive the lens adsorption mechanism 232 to move along the X-axis and Y-axis. The lens adsorption mechanism 232 includes a ninth mounting base 232a and a plurality of lens suction units. Each lens suction unit is arranged side by side on the ninth mounting base 232a. The lens suction unit includes a third cylinder 232b, a tenth mounting base 232c, a first suction tube 232d and a suction cup 232e. The third cylinder 232b is connected to the ninth mounting base 232a and is used to drive the tenth mounting base 232c to move along the Z-axis. The first suction tube 232d is fixed on the tenth mounting base 232c and its two ends are respectively connected to the suction cup 232e and the air pipe. The suction cup 232e is used to pick up the lens 5 on the material transfer platform 22 or the rotating platform 24.

[0079] The conveying unit 23 can achieve linear motion along the X, Y, and Z axes, and is mainly used to transport the lens 5. It includes a horizontal motion mechanism 231 and a lens adsorption mechanism 232. For example, the horizontal motion mechanism 231 drives the lens adsorption mechanism 232 to move along the X and Y axes, and the lens suction unit can drive the suction cup 232e to move the lens 5 along the Z axis. The lens adsorption mechanism 232 includes several lens adsorption units arranged side-by-side. The number of lens adsorption units is the same as the number of lenses 5 adsorbed on the rotating platform 24, and they are divided into two groups, each corresponding to two adsorption units 243. For example, if there are four lens adsorption units, it achieves a 2-to-2-to-place configuration. Each lens adsorption unit can work independently for exchanging adsorption and placement. Unevenness caused by processing errors of the lens carrier plate 4 or height differences caused by deformation of the lens carrier plate 4 can be overcome by independent vertical adsorption, ensuring stable adsorption and placement, improving work efficiency, and offering strong applicability. Figure 14 As shown, from right to left, the first two suction cups 232e are used to pick up materials, and the last two suction cups 232e are used to release materials.

[0080] In one embodiment, each adsorption unit 243 is arranged side by side, including a twelfth mounting base 243a, a second transmission mechanism 243b, at least one fixed base 243d, and at least one suction rod 243e. The twelfth mounting base 243a is connected to the eleventh mounting base 242. The second transmission mechanism 243b and the fixed base 243d are both connected to the twelfth mounting base 243a. The suction rods 243e are correspondingly built into the fixed bases 243d and rotatably connected to the fixed bases 243d for adsorbing the lens 5. When wiping the lens 5, the second transmission mechanism 243b drives the suction rods 243e to drive the lens 5 to rotate along the Z-axis.

[0081] Each adsorption unit 243 is arranged side-by-side on the eleventh mounting base 242. A cam divider 241 drives the rotating docking and conveying unit 23 and the cleaning unit 26. For example, each adsorption unit 243 includes two suction rods 243e, each used to adsorb one lens 5, enabling simultaneous operation of multiple lenses 5 and greatly improving efficiency. The second transmission mechanism 243b is a synchronous belt transmission mechanism, a rack and pinion transmission mechanism, or other transmission mechanisms commonly found in the prior art. In this embodiment, if the second transmission mechanism 243b is a synchronous belt transmission mechanism, a second tensioning mechanism 243c can also be provided connected to the twelfth mounting base 243a for tensioning the synchronous belt on the second transmission mechanism 243b. The specific number of second tensioning mechanisms 243c can be adjusted according to actual needs. Tensioning mechanisms are common structures in the prior art and will not be described in detail here. In addition to the rotating platform 24 itself needing to rotate, the lens 5 also needs to be driven to rotate during the wiping process. Therefore, a second transmission mechanism 243b is used to drive the suction rod 243e to rotate. That is, when the lens 5 at the wiping station needs to rotate, the second transmission mechanism 243b at the wiping station drives the suction rod 243e to rotate in coordination with the cleaning unit 26 to complete the wiping.

[0082] In one embodiment, the correction unit 25 includes a thirteenth mounting base 251, a fourth cylinder 252, a gripper cylinder 253, and two opposing V-blocks 254. The thirteenth mounting base 251 is connected to the second frame 21. The fourth cylinder 252 is connected to the thirteenth mounting base 251 and is used to drive the gripper cylinder 253 to move along the Z-axis. The gripper cylinder 253 is used to drive the two V-blocks 254 to move towards each other to achieve the clamping and correction of the lens 5, or to move in the opposite direction to achieve the release of the lens 5.

[0083] When the conveying unit 23 transfers the lens 5 from the material transfer platform 22 to the pick-and-place station of the rotating platform 24, the fourth cylinder 252 drives the gripper cylinder 253 to move down along the Z-axis to the position. After the gripper cylinder 253 moves down, it will center and clamp the lens 5 at the corresponding pick-and-place station on the rotating platform 24 to complete the centering. Then, the adsorption unit 243 firmly holds the centered lens 5. The gripper cylinder 253 resets and releases the lens 5. The fourth cylinder 252 resets and rises, making room for the adsorption unit 243 on the rotating platform 24 to rotate to the next station (wiping station). After the next set of lenses 5 to be wiped arrives at the position, the above steps are repeated. The problem of lens 5 being off-center can be solved by driving two V-shaped blocks 254 to clamp the lens 5 by the gripper cylinder 253. When the transport unit 23 picks up the lens 5, it can ensure that the center position of the lens 5 can be sucked up, so that the lens 5 can be accurately placed back into the lens carrier plate 4, and the lens 5 can be stably adsorbed to achieve uniform wiping, avoiding wiping the lens 5 out of the center position or wiping it off during the wiping process.

[0084] In one embodiment, the material feeding unit 262h includes an eighteenth mounting base 2601, a third motor 2602, a second roller 2603, a third roller 2604, a fifteenth mounting base 2605, and a fifth cylinder 2606. The eighteenth mounting base 2601 and the fifth cylinder 2606 are both connected to the fourteenth mounting base 262a. The third motor 2602 is connected to the eighteenth mounting base 2601 and is used to drive the second roller 2603 to rotate. The fifth cylinder 2606 is also used to drive the fifteenth mounting base 2605 to perform telescopic movement. The third roller 2604 is rotatably connected to the fifteenth mounting base 2605. The material belt 262e is fed by rotating the second roller 2603 and the third roller 2604 to clamp it.

[0085] The wiping unit 262i includes a nineteenth mounting base 2621, a sixth cylinder 2622, a fifth guide unit 2623, a sixteenth mounting base 2624, a spring 2625, a guide rod 2626, a seventeenth mounting base 2627, a feed belt clamping block 2628, and an infusion tube 2629. The nineteenth mounting base 2621 is connected to the fourteenth mounting base 262a. The cylinder body of the sixth cylinder 2622 and the fifth guide unit 2623 are both connected to the nineteenth mounting base 2621. The piston rod of the sixth cylinder 2622 is rotatably connected to the sixteenth mounting base 2624. The two ends of the guide rod 2626 are slidably connected to the sixteenth mounting base 2624 and the seventeenth mounting base 2627, respectively. Then, spring 2625 is sleeved on guide rod 2626 and its two ends abut against sixteenth mounting base 2624 and seventeenth mounting base 2627 respectively. Material strip pressing block 2628 is connected to seventeenth mounting base 2627 and abuts against material strip 262e. Infusion tube 2629 is connected to seventeenth mounting base 2627 and is used to drip liquid onto the part of material strip 262e that the material strip pressing block 2628 abuts against. Sixth cylinder 2622 is used to drive sixteenth mounting base 2624 to move linearly along fifth guide unit 2623, thereby driving seventeenth mounting base 2627 to move linearly along fifth guide unit 2623, so that material strip pressing block 2628 abuts against or moves away from material strip 262e.

[0086] The wiping unit 262i utilizes its own elasticity to buffer the pressure of the tape 262e during wiping. Specifically, the downward pressure from the sixth cylinder 2622 acts on the spring 2625, and after buffering, it acts on the lens 5, protecting it from impact. This maintains wiping force without breaking the tape 262e, improving wiping quality and preventing damage to the lens 5. Furthermore, the tape 262e's inherent elasticity and the buffer space provided by the wiping unit 262i allow it to adhere well to the lens. Even if the tape 262e is slowly removed and its shape changes, it maintains a consistent fit with the lens 5, fundamentally solving the problem of uneven force leading to incomplete cleaning. The tape clamping block 2628 has a groove and a hollow center near the lens, facilitating tape securing and preventing slippage, and helps adapt to the surface shape of the lens 5 for wiping. It should be noted that the tape clamping block 2628 and the seventeenth mounting base 2627 are detachably connected via multiple horizontally arranged pins. This facilitates adjusting the distance between the tape clamping block 2628 and the seventeenth mounting base 2627 to align the tape 262e, and also makes it easy to disassemble and replace the tape clamping block 2628 to accommodate tapes of different specifications and for cleaning and maintenance. The liquid dripped from the infusion tube 2629 is a cleaning solution, which is a commonly used liquid for lens cleaning in the prior art.

[0087] The third motor 2602 of the material feeding unit 262h is a stepper motor. The material belt 262e is clamped by the second roller 2603 and the third roller 2604. When feeding is required, the third motor 2602 drives the second roller 2603 to rotate and move the used material belt 262e. At the same time, the unused material belt 262e reaches the working position of the wiping unit 262i. The third motor 2602 stops running, and the first material belt clamping unit 262k and the second material belt clamping unit 262m clamp and lock the material belt 262e. If the first material belt clamping unit 262k and the second material belt clamping unit 262m can use a gripper cylinder to clamp the material belt 262e, the wiping unit 262i starts to work, and the material belt pressure block 2628 presses down the material belt 262e to wipe the lens 5. The hollowed-out portion of the tape pressing block 2628 can also be fitted with a high-elasticity sponge to conform to the surface of the lens 5. At this time, the cleaning liquid is automatically supplied to the sponge and absorbed by the tape 262e, which helps to quickly remove dirt. Then the lens 5 begins to rotate, and the fourth linear motion unit 261 drives each tape winding unit 262 to move horizontally until the tape 262e is completely removed from the lens 5, completing the wiping. Then the wiping unit 262i is reset, and the fourth linear motion unit 261 is reset. According to the process requirements, it is determined whether the feed third motor 2602 needs to refresh the portion of tape 262e pressed down by the wiping unit 262i.

[0088] In one embodiment, there are two tape winding units 262 arranged side by side. The tape winding unit 262 also includes a third tensioning mechanism 262f and a fourth tensioning mechanism 262g. The first reel 262b, the second tape clamping unit 262m, the third tensioning mechanism 262f, the wiping unit 262i, the first tape clamping unit 262k, the tape feeding unit 262h, the fourth tensioning mechanism 262g, and the second reel 262c are arranged sequentially along the winding direction of the tape 262e on each first roller 262j. The third tensioning mechanism 262f and the fourth tensioning mechanism 262g are used to tension the tape 262e.

[0089] The two tape winding units 262 can simultaneously wipe two lenses 5, greatly improving wiping efficiency. The specific number can be adjusted according to actual needs, matching the number of lenses adsorbed by the adsorption unit 243. The third tensioning mechanism 262f and the fourth tensioning mechanism 262g keep the tape 262e (clean cloth) taut and prevent it from becoming loose. This allows the wiping unit 262i to buffer when pressing down on the tape 262e, maintaining wiping force without breaking the tape 262e. This helps improve wiping quality and prevents damage to the lenses 5.

[0090] Working principle:

[0091] After the lens 5 is coated, it is placed in the lens carrier plate 4 and transferred to the first material bin 12 in the loading mechanism 1. After the first material bin 12 is full (that is, the lens carrier plate 4 is placed in the first slide 122 of each layer), the hooking unit 133 and the first lifting unit 14 of the loading mechanism 1 start to work, hooking the lens carrier plate 4 in the corresponding first slide 122 to the first synchronous belt conveyor unit 132. The first synchronous belt conveyor unit 132 docks with the carrier plate conveyor unit 221 of the material transfer platform 22, transporting the lens carrier plate 4 to the carrier plate of the material transfer platform 22. Above the positioning unit 222, the lens picking unit of the conveying unit 23 lifts and positions the two lenses 5 to be wiped to the pick-and-place station on the rotating platform 24. The alignment unit 25 adjusts the lenses 5 to the center of the pick-and-place station, and then the suction rod 243e of the adsorption unit 243 adsorbs and fixes the lenses 5. The pick-and-place station rotates 180° to the wiping station via the cam divider 241, automatically supplying cleaning liquid to the surface of the lenses 5 or the material belt 262e. The wiping unit 262i then... The cleanroom cloth is pressed down onto the surface of lens 5, and the suction rod 243e begins to rotate 360°. At the same time, the fourth linear motion unit 261 starts to drive the material belt winding unit 262 to move horizontally, carrying away the oil and dust on the surface of lens 5. After wiping, after each set of lenses 5 is cleaned, the material belt feeding unit 262h drives the cleanroom cloth to rotate to change the belt until the next lens 5 is wiped, ensuring that a new cleanroom cloth is used. The wiping station starts to rotate 180° to the pick-up and drop-off station, where the lens suction unit of the conveying unit 23 transports the wiped lens 5 to the lens carrier plate 4. This process repeats until all lenses 5 in the lens carrier plate 4 are cleaned and wiped. Then, the carrier plate positioning unit 222 of the material transfer platform 22 lowers and releases the lens carrier plate 4. The carrier plate conveying unit 221 of the material transfer platform 22 transports the lens carrier plate 4 to the second synchronous belt conveying unit 332 of the unloading mechanism 3. The second lifting unit drives the second hopper 32 to move along the Z-axis and connect with the second synchronous belt conveying unit 332. The check valve unit 333 hooks the lens carrier plate 4 into the second hopper 32. This process repeats, achieving fully automatic lens loading-cleaning-unloading. An alarm is triggered when the first hopper 12 is empty or the second hopper 32 is full to ensure sufficient material supply or timely unloading and collection. Alternatively, it can be connected to other machines to achieve automatic loading and unloading. If an alarm is triggered after wiping, AGV intelligent vehicles can be added for loading and unloading, completely replacing manual labor and achieving automated production line production. Specific processes can also be adjusted according to actual needs.
