Abstract
Description
Technical Field
[0001] This application relates to the field of lens assembly technology, and more specifically, to a feeding device and bonding equipment. Background Technology
[0002] The PSA adhesive used in lens assembly typically has thickened auxiliary ears on its sides. These ears are primarily used for disassembly, adjustment, or positioning calibration of the PSA adhesive in subsequent processes. However, due to the protruding nature of these auxiliary ears, interlayer interference can easily occur during the stacking of PSA adhesive. If too many adhesives are stacked at once, it can easily cause jamming or even deformation of the adhesive parts, severely affecting the stability of subsequent material handling and bonding operations. Therefore, existing feeding devices must strictly limit the number of adhesives stacked at a time, resulting in a small storage capacity that is difficult to adapt to the demands of efficient and continuous production.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0025] The feeding device 10 according to an embodiment of this application will now be described in detail with reference to the accompanying drawings.
[0026] like Figure 1 As shown, a feeding device 10 according to an embodiment of this application includes: a material basket 11 and a lifting unit 12.
[0027] Specifically, the upper side of the material basket 11 is provided with a bottom material support surface for stacking PSA parts. The outer periphery of the bottom material support surface of the material basket 11 is provided with a support structure 111 for supporting the partition. The upper side of the partition is provided with an additional material support surface for stacking PSA parts. The material basket 11 is provided with a positioning post 112 in the bottom material support surface. The positioning post 112 is used to horizontally limit the PSA parts and the partition. The lifting unit 12 is provided with a bracket 121 that is movable along its height direction. The bracket 121 is used to support the material basket 11 and drive it to move in the height direction.
[0028] In some embodiments, such as Figure 1As shown, the feeding device 10 according to an embodiment of this application mainly includes a material basket 11 and a lifting unit 12. The material basket 11 has a bottom support surface on its upper side for stacking PSA parts. Multiple spaced positioning posts 112 are fixedly connected to the bottom support surface. A support structure 111 is also provided on the upper side of the material basket 11, located on the outer periphery of the bottom support surface. The upper end of the support structure 111 supports a partition. An additional support surface parallel to the bottom support surface is formed on the upper side of the partition. A bottom stacking space for stacking PSA parts is formed between the bottom support surface and the partition, and an additional stacking space for stacking PSA parts is formed on the upper side of the additional support surface. The bottom stacking space uses the bottom support surface as its bottom reference, and the additional stacking space uses the additional support surface as its bottom reference. The lifting unit 12 mainly includes a vertically arranged pneumatic slide table. A bracket 121 is mounted on the slider of this pneumatic slide table. The pneumatic slide table drives the bracket 121 to rise and fall, and the bracket 121 drives the entire material basket 11 to rise and fall. In this embodiment, the positioning post 112 is adapted to the positioning holes on the PSA component and the partition. The positioning post 112 can horizontally limit the PSA component and the partition, thereby facilitating the neat stacking of the PSA component and the partition into the material basket 11 and avoiding problems such as offset or misalignment during stacking. Simultaneously, it can achieve primary positioning of the PSA component, ensuring that the subsequent gripping, transfer, and bonding operations of the bonding module 30 with the lens can be accurately performed.
[0029] When the feeding device 10 according to this application is in use, PSA parts are stacked on both the bottom material support surface and the additional material support surface. After the bonding module 30 removes the topmost PSA part, the lifting unit 12 drives the material basket 11 to rise a second predetermined distance corresponding to the PSA part, so that the new topmost PSA part is still kept at the picking height; after the bonding module 30 removes the partition, the lifting unit 12 drives the material basket 11 to rise a first predetermined distance corresponding to the partition, and continues to send the remaining PSA parts to the picking height, thereby realizing uninterrupted continuous feeding.
[0030] Therefore, according to the feeding device 10 provided in this embodiment, the supporting structure 111 can support the partition with an additional material bearing surface, thereby forming a bottom stacking space and an additional stacking space distributed vertically within a single material basket 11. This not only effectively improves the storage capacity and space utilization, but also avoids the problem of PSA parts tilting and the positioning column 112 jamming caused by excessive stacking at one time, ensuring that material picking is always stable and reliable.
[0031] In some specific embodiments of this application, the upper side of the material basket 11 is provided with a plurality of supporting structures 111, the height of each supporting structure 111 increasing sequentially, so as to support a plurality of partitions at different heights.
[0032] Specifically, the upper side of the material basket 11 has at least two levels of support structures 111 of different heights on the outer periphery of the bottom material-bearing surface; the first-level support structure 111 supports the first partition, forming a bottom stacking space between the first partition and the bottom material-bearing surface; the second-level support structure 111 supports the second partition, forming a first additional stacking space between the second partition and the first partition, and a second additional stacking space is formed on the upper side of the second partition; if more levels of support structures 111 are provided, multiple additional stacking spaces can be formed sequentially at higher positions. The upper surface of each partition constitutes a new material-bearing surface for PSA parts to be stacked in layers, thereby enabling three or more layers to be stacked without increasing the planar dimensions of the material basket 11, thus further increasing the storage capacity.
[0033] In some optional examples of this application, the supporting structure 111 includes multiple support frames. In this example, there are two support frames located on both sides of the length direction of the bottom material bearing surface. The support frame is provided with two support columns along the width direction of the bottom material bearing surface, and the four support columns can provide reliable support at the four corners of the partition.
[0034] According to one embodiment of this application, at least two of the supporting structures 111 are distributed circumferentially along the bottom material bearing surface; and / or, at least two of the supporting structures 111 are arranged from the center of the bottom material bearing surface outwards, and their supporting heights increase sequentially.
[0035] In other words, the distribution of multiple supporting structures 111 includes, but is not limited to, the following two cases: Case 1: The two supporting structures 111 are distributed circumferentially along the bottom supporting surface. In this case, the unidirectional size of the material basket 11 can be avoided, ensuring the overall structure is compact. At the same time, it can prevent the stiffness of the partition from decreasing and deforming due to unidirectional lengthening, ensuring that the partition can bear load smoothly and the material can be picked up reliably.
[0036] Scenario 2: The two support structures 111 are arranged in a stepped manner from the center of the bottom support surface outward to the outer periphery of the bottom support surface; in this case, the multi-level support structure 111 can be integrally formed into a continuous stepped structure, without the need for separate processing and assembly, the structure is simple and easy to produce and assemble.
[0037] In some optional examples of this application, the upper side of the material basket 11 is provided with at least one stepped structure, the stepped structure having multiple steps of different heights, and the steps at the same height in all the stepped structures together constitute a supporting structure 111.
[0038] In other words, one or more stepped structures are fixedly connected to the upper side of the material basket 11. The stepped structure consists of multiple steps of different heights, with the height of the steps increasing sequentially from the center of the bottom material-bearing surface outwards. The steps at the same height in all the stepped structures together form a support structure 111, which can effectively simplify the structure of the material basket and facilitate production assembly.
[0039] It should be noted that the number of stepped structures can be determined based on the specific structure. If a single step is sufficient to reliably support the partition, then one stepped structure is sufficient to meet the requirements. In this example, there are four stepped structures located at the four corners of the bottom support surface.
[0040] According to one embodiment of this application, the feeding device 10 further includes: a connecting seat 13 for supporting and positioning the material basket 11; a base 14, wherein the connecting seat 13 is movably disposed on the base 14 between a first position and a second position along its length direction; in the first position, the connecting seat 13 is located below the bracket 121, and the bracket 121 can cooperate with the material basket 11 from below and drive it to rise and fall; in the second position, the connecting seat 13 moves out from below the bracket 121.
[0041] In other words, the feeding device 10 is provided with a base 14 and a connecting seat 13. The upper side of the connecting seat 13 is provided with multiple protruding positioning parts, and the lower side of the material basket 11 is provided with mating holes adapted to the positioning parts. The connecting seat 13 is movably mounted on the upper side of the base 14 along its length direction (i.e., the first direction) through a guide rail slider structure, and can switch between a first position and a second position. The first position can be a feeding position, and the second position can be a position suitable for picking up and placing the material basket 11. When the connecting seat 13 is in the first position, it is located directly below the bracket 121; when the connecting seat 13 is in the second position, it moves out from under the bracket 121.
[0042] The feeding device 10 according to this embodiment is in its initial state upon first use. In this state, the bracket 121 is in its initial position with the lowest travel, and the connecting seat 13 is in its second position. After the operator places and positions the material basket 11 onto the connecting seat 13, the operator drives the connecting seat 13 to switch from the second position to the first position. During this switching process, the bracket 121 can be simultaneously inserted into the gap between the material basket 11 and the base 14. After the connecting seat 13 switches to the first position, the bracket 121 can support the material basket 11 from below and drive the material basket 11 to complete the lifting and lowering action. When the material in the material basket 11 is exhausted and needs to be replaced, the bracket 121 is controlled to fall back to the initial position, and the material basket 11 is then supported and positioned again by the connecting seat 13. Subsequently, the connecting seat 13 is driven to move from the first position to the second position, thus completing the removal and replacement operation of the material basket 11.
[0043] This embodiment, by configuring a connecting seat 13 that can switch back and forth between a first position and a second position, enables the material basket 11 to quickly switch between the working position and the pick-up / place position at the corresponding position of the bracket 121. Compared with the fixed material basket 11 feeding structure, it greatly shortens the material changing operation time, reduces the equipment downtime waiting time, and significantly improves the continuous operation efficiency of the feeding device 10.
[0044] In some specific embodiments of this application, the feeding device 10 further includes a partition detection unit located beside the bracket 121, which is used to trigger the lifting unit 12 to drive the basket 11 to rise a first predetermined distance after detecting that the partition has been removed.
[0045] Specifically, the feeding device 10 is equipped with a partition detection unit, and a connecting frame is fixedly connected to the slide rail of the lifting unit 12. The partition detection unit is fixedly connected to the connecting frame. The partition detection unit can be a proximity sensor. When the partition moves up and down with the material basket 11 to a preset detection position, the partition can completely block the detection light path. When the partition is removed, the detection light path is restored, the partition detection unit is triggered, and a drive signal is sent to the lifting unit 12, instructing the lifting unit 12 to drive the material basket 11 to rise a first predetermined distance.
[0046] Therefore, the feeding device 10 according to this application does not have strict limitations on the number of PSA parts stacked at one time. It can accurately control the lifting and lowering of the material basket 11 by detecting the removal status of the partition, without relying on preset material stacking height parameters. This can effectively avoid feeding abnormalities caused by material stacking errors. At the same time, it greatly reduces the initial debugging cost of the feeding device 10, without having to repeatedly adjust parameters for the stacking height of different specifications of PSA parts, which significantly improves the adaptability and operational stability of the device to diverse production needs.
[0047] In some optional examples of this application, a fixing frame 16 is fixedly provided on the upper side of the base 14. The fixing frame 16 includes a first bracket and a second bracket, which are located on both sides of the bracket 121 in the second direction (i.e., the width direction of the connecting seat 13). The feeding device 10 is also equipped with a positioning detection unit 15, which can be a through-beam photoelectric sensor. The transmitting end of the positioning detection unit 15 is located on the first bracket, and the receiving end is located on the second bracket. The positioning detection unit 15 is used to detect whether the top PSA has reached a predetermined height. When the top PSA has not reached the predetermined height, the PSA cannot block the detection light path, and the positioning detection unit 15 outputs a non-position signal, triggering the lifting unit 12 to drive the basket 11 to rise continuously. When the top PSA rises to the predetermined height and completely blocks the detection light path, the positioning detection unit 15 outputs a position signal, and the lifting unit 12 immediately stops, so that the PSA is accurately stopped within the picking range of the bonding module 30.
[0048] The feeding device 10 is also equipped with a material shortage detection unit, which can be a through-beam photoelectric sensor. The transmitter of the material shortage detection unit is located on the first bracket, and the receiver is located on the second bracket. The material shortage detection unit is used to detect whether the material basket 11 is short of material. When the stacking height of the PSA parts in the material basket 11 reaches a preset threshold, that is, when there is a predetermined number of PSA parts, the PSA parts can completely block the detection light path, and the receiver has no detection signal feedback. The material shortage detection unit determines that the material basket 11 is in a material-rich state, and the feeding device 10 maintains normal operation mode. When the PSA parts in the material basket 11 are taken and the remaining number is lower than the preset threshold, the detection light path is restored to conduction, the receiver receives the signal and generates a material shortage judgment signal, so that the control system can issue a replenishment reminder in a timely manner.
[0049] According to one embodiment of this application, brush assemblies 17 are respectively provided on opposite sides of the first support and the second support, with the bristles of the brush assemblies 17 extending toward the material basket 11. During the material picking operation of the bonding module 30, when the bonding module 30 adsorbs and lifts the top PSA part, the bristles can apply a reverse combing force to the lower PSA parts that are adhered to the top PSA part due to electrostatic adsorption, and brush the adhered PSA parts into the material basket 11 in a timely manner, which can effectively avoid the bonding module 30 adsorbing multiple PSA parts in a single material picking operation.
[0050] In some specific embodiments of this application, the feeding device 10 is further provided with a first ionizing air assembly. During the process of the bonding module 30 lifting the PSA part, the first ionizing air assembly can directionally blow ionizing air onto the lifted PSA part at a preset material picking position, thereby effectively removing the static electricity carried by the PSA part and eliminating the adhesion problem between PSA parts caused by static electricity.
[0051] According to one embodiment of this application, the feeding device 10 includes multiple sets of lifting units 12 and a corresponding number of material baskets 11, the material baskets 11 being used to stack the same or different PSA parts.
[0052] In other words, the feeding device 10 is equipped with multiple sets of lifting units 12, and each set of lifting units 12 is adapted to a material basket 11, with each set of lifting units 12 and material basket 11 arranged in a one-to-one correspondence. For example, the number of lifting units 12 and material baskets 11 can both be set to two sets, with one set of material baskets 11 used to stack the PSA parts required for the left lens and the other set of material baskets 11 used to stack the PSA parts required for the right lens; based on this configuration, the PSA bonding equipment can simultaneously perform PSA part bonding operations on the left and right lenses of the display device, effectively shortening the bonding process time of a single display device and significantly improving overall production efficiency.
[0053] The number of lifting units 12 and material baskets 11 can also be expanded to three, four or six sets according to actual production needs. By stacking PSA parts of different specifications (such as different thicknesses and different sizes) in multiple sets of material baskets 11, the bonding requirements of PSA parts of different lenses or different models of display devices can be met, which greatly improves the adaptability and production flexibility of the feeding device 10, effectively reduces the downtime of equipment adjustment due to changing material specifications, and further improves the continuous operation efficiency of the production line.
[0054] In summary, the feeding device 10 provided in this embodiment can support the partition with an additional material-bearing surface through the set support structure 111, thereby forming a bottom stacking space and an additional stacking space distributed vertically within a single material basket 11. This not only effectively improves the storage capacity and space utilization, but also avoids the tilting and jamming of PSA parts caused by excessive stacking at one time, ensuring that material retrieval is always stable and reliable.
[0055] like Figures 2 to 5 As shown, embodiments of this application also provide a PSA bonding device, including the feeding device 10 described in any of the above embodiments. Since the feeding device 10 according to the embodiments of this application has the above-described technical effects, the PSA bonding device according to the embodiments of this application also has corresponding technical effects, which will not be repeated in this embodiment.
[0056] In some specific embodiments of this application, the PSA bonding equipment further includes: a body 20, the body 20 being provided with the feeding device 10, a bonding module 30 and a cleaning device 40; the bonding module 30 is used to bond the PSA parts in the material basket 11 to the lens, and is also used to transfer the bonded lens to the cleaning device 40 for cleaning.
[0057] Specifically, such as Figures 2 to 4 As shown, the PSA bonding equipment according to an embodiment of this application mainly includes a body 20, a feeding device 10, a bonding module 30, and a cleaning device 40, all of which are located within the body 20. The bonding module 30 is configured to pick up PSA parts from the material basket 11 of the feeding device 10 and bond the PSA parts to the lens, and to pick up and remove partitions from the material basket 11 of the feeding device 10; furthermore, the bonding module 30 is configured to transfer the bonded lens to the cleaning device 40 for cleaning, thereby removing dust and other impurities adhering during the bonding process, thus ensuring the imaging effect of the lens.
[0058] According to one embodiment of this application, the cleaning device 40 includes: a fixing unit 41 disposed on the body 20, the fixing unit 41 having a fixing component 411 movable between the cleaning station and the unloading station, the fixing component 411 being used to receive and fix the lens; and a cleaning component 42 disposed on the body 20 and switchable between a first state and a second state; when the cleaning component 42 is in the first state, it extends into the inner cavity of the lens located at the cleaning station; when the cleaning component 42 is in the second state, it exits the inner cavity of the lens.
[0059] In other words, the cleaning device 40 mainly includes a fixing unit 41 and a cleaning component 42, both of which are mounted on a base 21 within the machine body 20. The fixing unit 41 includes a horizontally arranged pneumatic slide, on which a base plate is fixedly connected. A fixing component 411 for receiving and fixing the lens is fixedly connected to the upper side of the base plate. The fixing unit 41, via the pneumatic slide, can drive the fixing component 411 to reciprocate between the cleaning station and the unloading station. The cleaning component 42 is mounted on the base 21. When the fixing component 411 is in the cleaning station, its position corresponds to that of the fixing component 411; when the fixing component 411 is in the unloading station, its position corresponds to that of the unloading port of the machine body 20, facilitating the transfer of the lens to other equipment for subsequent processing. The cleaning component 42 can be switched between a first state and a second state. When the cleaning component 42 is in the first state, it extends into the inner cavity of the lens to clean the inner cavity of the lens. When the cleaning component 42 is in the second state, it exits the inner cavity of the lens so that the fixing unit 41 can move the lens to the unloading station.
[0060] According to one embodiment of this application, the bonding module 30 mainly includes a PSA material picking unit 31, a PSA moving unit 32, and a module transport unit 33 distributed along a first direction. The PSA material picking unit 31 includes a first guide rail module disposed on the base 21 and arranged along a second direction; a vertically arranged second guide rail module is fixedly connected to the slider of the first guide rail module; a first motor is fixedly connected to the slider of the second guide rail module; a first suction cup is fixedly connected to the output end of the first motor; the first guide rail module can drive the first suction cup to move between its first and second ends. The first end of the first guide rail module is close to the feeding device 10, and the second end is close to the PSA moving unit 32. The PSA moving unit 32 includes a third guide rail module disposed on the base 21 and arranged along the first direction; a negative pressure platform is fixedly connected to the slider of the third guide rail module; the third guide rail module can drive the negative pressure platform to move between its first and second ends; its first end is close to the PSA material picking unit 31, and its second end is close to the module transport unit 33. The PSA moving unit 32 is provided with a PSA upper film tearing unit 34 on the side near the PSA material picking unit 31, and the module transport unit 33 is provided with a PSA lower film tearing unit 35 on the side.
[0061] When using the PSA bonding equipment according to the embodiments of this application, firstly, the PSA material handling unit 31 transports the PSA component provided by the feeding device 10 to the negative pressure stage located at the first end of the third guide rail module via the first suction cup; then, the negative pressure stage adsorbs and fixes the PSA component; then, the PSA upper film peeling unit 34 peels off the upper film of the PSA component and transfers it to the first receiving box; then, the third guide rail module drives the negative pressure stage to move to its second end; then, the module transport unit 33 transports the lens to the negative pressure stage and applies pressure to the lens for a predetermined time to bond the PSA component to the lens; then, the module transport unit 33 transports the lens to the corresponding position of the PSA lower film peeling unit 35; then, the PSA lower film peeling unit 35 peels off the lower film of the PSA component and transfers it to the second receiving box; then, the module transport unit 33 transports the lens to the cleaning device 40 for cleaning.
[0062] The bonding module 30 also includes a PSA lower vision unit 36, a PSA upper vision unit 37, a module scanning unit 38, and a module lower vision unit 39 mounted on the base 21. The PSA lower vision unit 36 is located between the first and second ends of the first guide rail module, while the PSA upper vision unit 37 and the module scanning unit 38 are located between the first and second ends of the third guide rail module. The module lower vision unit 39 corresponds to the module transport unit 33. The PSA lower vision unit 36 photographs and positions the PSA component picked up by the first suction cup, facilitating the PSA material handling unit 31 to adjust the position of the PSA component. The PSA upper vision unit 37 photographs the PSA component carried on the negative pressure platform to determine the position of the PSA after film removal on the negative pressure platform, enabling the module transport unit 33 and the PSA moving unit 32 to accurately assemble the PSA and lens using visual algorithms based on the photographic data from the PSA upper vision unit 37.
[0063] The PSA upper film tearing unit 34 and the PSA lower film tearing unit 35 have the same structure. Both units include a fourth guide rail module 341, with a telescopic cylinder 342 fixedly connected to the slider of the fourth guide rail module 341. The output end of the telescopic cylinder 342 is tilted upwards, and its conveying end is fixedly connected to a pneumatic gripper 343 for clamping the upper or lower film of the PSA component. Film tearing is achieved through the coordinated operation of the fourth guide rail module 341 and the telescopic cylinder 342. Compared to the single-motion method of separately setting the telescopic cylinder 342 and the pneumatic gripper 343, this significantly shortens the single extension stroke of the telescopic cylinder 342, avoiding motion lag or vibration problems caused by excessively long strokes. Simultaneously, the composite motion trajectory better matches the mechanical requirements of film tearing, making the tearing process smoother and more efficient. In addition, a film layer detection sensor 344 is fixedly connected to the upper gripper of the pneumatic gripper 343. The film layer detection sensor 344 adopts a miniature photoelectric sensor to detect in real time whether the pneumatic gripper 343 has successfully gripped the upper or lower film, and whether the film layer has detached from the gripper after the film tearing operation.
[0064] The module handling unit 33 includes a fifth guide rail module 331, which has a first slider and a second slider movable along a first direction. The first slider is used to connect to the first handling assembly 332, and the second slider is used to connect to the second handling assembly 333. The first handling assembly 332 includes a vertically arranged sixth guide rail module, which is fixed to the first slider. A second motor is fixedly connected to the slider of the sixth guide rail module, and a second suction cup is fixedly connected to the output end of the second motor. The second suction cup is used to pick up the lens to be bonded to the PSA component. The fifth guide rail module 331 and the second motor are used to adjust the position of the lens, and the sixth guide rail module is used to drive the suction cup to rise and fall to apply the pressure required for bonding the PSA component to the lens. The second transport assembly 333 includes a vertically arranged seventh guide rail module, which is arranged along the first direction. The slider of the seventh guide rail module is fixedly connected to a vertically arranged eighth guide rail module. A third suction cup is fixedly connected to the slider of the eighth guide rail module. The third suction cup can transport the bonded lens to the lower film peeling position for peeling off the lower film, and then transport the lens to the cleaning device 40 after peeling off the lower film.
[0065] In some optional examples of this application, the cleaning component 42 includes: an air blowing member 421, which is movably disposed on the body 20 along the height direction between a third position and a fourth position; in the third position, the air blowing member 421 extends into the lens cavity; in the fourth position, the air blowing member 421 exits the lens cavity; and an air suction member 422, which is disposed on the body 20, and when the fixing unit 41 is located at the cleaning station, the air suction member 422 faces the lens cavity.
[0066] Specifically, the cleaning assembly 42 includes a blowing component 421, an suction component 422, and a first driving component (e.g., a cylinder). The blowing component 421 corresponds to the position of the fixed assembly 411 located at the cleaning station. The blowing component 421 is movably disposed on the base 21 along the height direction between a third position and a fourth position, where the third position can be a high position and the fourth position can be a low position. The suction component 422 is configured as a ring structure, corresponding to the position of the blowing component 421 located at the cleaning station, and is fixedly connected to the base 21. When cleaning the lens, the fixed assembly 411 is first moved to the cleaning station so that the suction component 422 is directly opposite the opening below the lens. Then, the first driving component drives the suction component 422 from the fourth position to the third position, so that the suction component 422 extends into the inner cavity of the lens. Then, the blowing component 421 is controlled to blow air into the lens, while the suction component 422 is controlled to suction air below the inner cavity of the lens.
[0067] Thus, the blowing component 421 can blow away the attached dust and debris from the inner wall of the lens, and the blown-off impurities will be sucked away by the suction component 422 below in time. The closed-loop cleaning process can quickly complete the cleaning of the lens cavity, and can also ensure the air pressure balance of the lens cavity through the bidirectional flow of air, avoiding lens damage caused by air pressure imbalance in the cavity; at the same time, it can effectively prevent the dust raised during the cleaning process from spreading into the body 20 and causing secondary pollution to other products or components.
[0068] In some specific embodiments of this application, the fixing component 411 is configured as a clamping component for holding and fixing a lens.
[0069] In other words, the fixing component 411 is a clamping component, which includes a gripper cylinder. The two grippers of the gripper cylinder are equipped with gripping parts for clamping the lens, and the gripping parts are also equipped with receiving parts for supporting the lens. When the fixing component 411 moves from the unloading station to the cleaning station and receives the lens, the bottom of the lens first comes into contact with the receiving parts of the two grippers, and the receiving parts achieve initial support and positioning of the lens. Subsequently, the gripper cylinder drives the two grippers to clamp towards each other, so that the inner side of the gripper fits tightly against the outer wall of the lens, thereby achieving stable fixing of the lens in the cleaning station and providing a reliable positioning basis for subsequent cleaning operations.
[0070] In this embodiment, by adjusting the distance between the grippers, the clamping and fixing requirements of lenses of various specifications can be met within a certain range, which broadens the application range of PSA bonding equipment and enhances the equipment's adaptability to multiple production scenarios.
[0071] In some optional examples of this application, the clamping element is detachably connected to the clamping jaws of the clamping cylinder, for example, by means of screws, so that different models of clamping elements can be replaced to further broaden the application range of PSA bonding equipment.
[0072] According to one embodiment of this application, the air blowing member 421 is rotatable about its axis, and the upper end of the air blowing member 421 is provided with an air blowing slit 4211 extending to its sidewall.
[0073] Specifically, the cleaning assembly 42 also includes a rotary motor, which is fixedly connected to the base 21. The lower end of the air blowing component 421 is connected to a connecting shaft, and the lower end of the connecting shaft is connected to the first driving component through a rotary joint. The output end of the rotary motor is connected to the connecting shaft at the lower end of the air blowing component 421 for transmission. The rotary motor can drive the air blowing component 421 to rotate around its own axis. The upper end of the air blowing component 421 is provided with an air blowing gap 4211, and at least one end of the air blowing gap 4211 extends to the side wall of the air blowing component 421, so that the air blowing port of the air blowing component 421 is formed into an L-shaped structure or a U-shaped structure, thereby enabling the air blowing component 421 to blow air onto the upper wall and side wall of the lens cavity simultaneously. When the air blowing component 421 rotates at a constant speed under the drive of the rotary motor, the airflow formed by the air blowing gap 4211 will perform a circular scan along the circumference of the lens cavity. The airflow coverage can completely cover all the walls of the lens cavity, which can blow away all the dust, debris and other impurities attached to the walls, thus ensuring the cleaning effect of the cleaning component 42.
