Description

Technical Field

[0001] This invention belongs to the field of ultra-thin flexible screens, specifically relating to a process for the oblique loading, flattening and material placement, and reversing basket processing of ultra-thin flexible screens. Background Technology

[0002] Currently, ultra-thin flexible screens are display devices made of soft materials that can be bent or even folded. Their screen thickness can be as thin as about 0.01mm and can withstand extremely small bending radii (up to 1mm), enabling free bending and folding. They are widely used in consumer electronics such as foldable mobile phones and flexible screen bracelets, as well as in automotive displays, wearable medical devices, and other products.

[0003] However, to meet processing or orientation requirements, the ultra-thin flexible screen needs to be transferred from basket A to basket B (referred to as basket transfer between baskets A and B). This transfer process includes a material retrieval step from basket A, a material transfer and placement step, and a material loading step into basket B. Baskets A and B are loaded with ultra-thin flexible screens based on horizontally arranged and vertically aligned grids, with one ultra-thin flexible screen placed in each grid. However, the following technical defects exist in actual operation: 1) During the movement of basket A, the ultra-thin flexible screen will inevitably shift within the material compartment, causing the corners of multiple ultra-thin flexible screens to be misaligned when picking up materials from basket A. This not only increases the difficulty of transferring and placing materials, but also significantly increases the rate of corner collision damage caused by material placement. 2) During the transfer and placement process of ultra-thin flexible screen, since the ultra-thin flexible screen has a certain degree of flexibility, if the entire flexible screen is directly dropped into the material tank without external force during the placement process, the ultra-thin flexible screen will inevitably arch or bend due to its flexibility. Therefore, there is a high edge and corner damage rate during the dropping process. 3) The main consideration for the transfer and loading steps is the orientation of the ultra-thin flexible screen's basket. For example, the basket is loaded based on the long side of the ultra-thin flexible screen (referred to as long side basket loading) or based on the short side of the ultra-thin flexible screen (referred to as short side basket loading). That is, when the long side basket and the short side basket are reversed, not only does the material tray need to rotate 90° to achieve position exchange, but it is also impossible to simultaneously load and unload the B basket. In other words, after rotating 90° to reverse the orientation, it is necessary to wait for the ultra-thin flexible screen on the material tray to be removed before rotating 90° to reset and then loading the ultra-thin flexible screen into the A basket. Therefore, the operation process is complicated and inefficient. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a novel process for the oblique loading, flattening and material placement, and reversing basket processing of ultra-thin flexible screens.

[0005] To achieve the above objectives, the present invention adopts the following solution: A process for the oblique placement, leveling, and reversing of an ultrathin flexible screen in a rotating basket includes the following steps: S1, A basket material retrieval step, including the A basket filling process and the material retrieval process by the first robot adsorbing the ultra-thin flexible screen from the A basket; S2, Transfer and material placement steps, including the material placement process and the reversing process; S3, the loading step of basket B, includes the process of the second robot taking out the ultra-thin flexible screen from step S2 and inserting it into basket B, and the transfer process of basket B, especially, In step S1, the ultra-thin flexible screen is positioned at the same angle and with equal insertion length in basket A, using one side and one side of the front and back as a reference, and the first robot simultaneously picks up multiple ultra-thin flexible screens. In the material placement process of step S2, firstly, multiple ultra-thin flexible screens are aligned and adsorbed onto the picking hand of the first robot by aligning the two ends of the reference side facing each other; secondly, based on the number of material platforms that the picking hand picks up and matches them, the material platforms of each ultra-thin flexible screen are placed sequentially. During the material placement, the ultra-thin flexible screens on the upper part of the picking hand are positioned above the material slots of the material platform and are positioned with the reference side as the adsorption reference. Then, they are gradually adsorbed from the material slots to the opposite side of the reference side. At the same time, the picking hand rotates relative to each other to make the ultra-thin flexible screens gradually detach from the picking hand and fall into the material slots in turn. The ultra-thin flexible screens are pushed flat by the gradual adsorption. Simultaneously, the two sets of material platforms arranged on the dual-station rotating platform with interchangeable positions simultaneously perform the A basket placement and B basket retrieval. In step S3, firstly, based on the displacement of the material platform on the rotating platform to avoid the manipulator of the second robot, and the direction of the manipulator inserting into the material slot is perpendicular to the direction of the picker entering the material slot below, the thin flexible screens on multiple material platforms are sequentially adsorbed in the same direction and in the same position; secondly, keeping the manipulator inserted into the material slot in the same direction, the reversed ultra-thin flexible screen is inserted into the material compartment of basket B.

[0006] Preferably, in step S1, the ultra-thin flexible screen loaded in basket A moves with basket A and enters the feeding area. Simultaneously, basket A is lifted from the sides corresponding to the front and back of the ultra-thin flexible screens, and each ultra-thin flexible screen is placed parallel and obliquely in the material compartment of basket A. This lifting operation ensures that the ultra-thin flexible screens maintain the same angle in the material compartment, providing conditions for the ultra-thin flexible screens to be picked up.

[0007] Preferably, in step S1, after adjusting the same angle, basket A is placed horizontally so that the ultra-thin flexible screens in each compartment have equal insertion lengths. This horizontal placement of basket A ensures that the ultra-thin flexible screens maintain equal insertion lengths in the compartments, providing conditions for the absorption of the ultra-thin flexible screens.

[0008] According to a specific embodiment and preferred aspect of the present invention, each material compartment consists of a bottom support rod and comb-tooth rods located on both sides of the support rod. Multiple support slots perpendicular to the length direction of the support rod are arranged side-by-side on the support rod. Corresponding material compartments are formed between the comb-tooth slots corresponding to each support slot. Each ultra-thin flexible screen is inserted into the support slot from a reference side and abuts against the side of the corresponding comb tooth from the reference side. The support slots form a bottom support, and the comb-tooth slots form a side support, thereby relatively flattening the ultra-thin flexible screen during insertion into the corresponding material compartment, thus maintaining the same reference for adsorption and material handling, and improving the corner alignment of the ultra-thin flexible screen.

[0009] Preferably, there are multiple support poles with corresponding support slots, and each ultra-thin flexible screen is inserted into the multiple parallel support slots from the reference side. Utilizing multi-point alignment to form aligned insertion on the reference side is more conducive to the parallelism of the ultra-thin flexible screens in basket A.

[0010] In some specific embodiments, two comb bars form a group, with at least one group arranged in the depth direction of the material compartment. The number of groups is selected based on the size of the ultra-thin flexible screen to ensure that the ultra-thin flexible screen is placed obliquely in each material compartment in a parallel state. Selection based on the size of the ultra-thin flexible screen allows all ultra-thin flexible screens to be inserted and positioned under the same reference, which not only reduces the probability of edge and corner damage later but also facilitates the flattening and placement of the ultra-thin flexible screen.

[0011] Preferably, the material handling hand has multiple parallel material shovels, and these shovels can be matched with corresponding material compartments to pick up materials by adhering the shovel surfaces parallel to the ultra-thin flexible screen. This avoids damage to the edges and corners of the ultra-thin flexible screen during material picking.

[0012] Furthermore, in step S2, during the opposing alignment, the ultra-thin flexible screen is mounted on the material handling hand. At this time, the negative pressure disappears, and alignment is performed based on the relative movement of the alignment components. Since the ultra-thin flexible screen is in a horizontal state, further alignment is performed to ensure that the positions of multiple ultra-thin flexible screens are relatively aligned.

[0013] According to another specific embodiment and preferred aspect of the present invention, the material platform used in step S2 includes multiple material rods forming a notch at the top of each material rod, and the multiple notches are assembled to form a material trough. Based on the surrounding material rods, it is advantageous for the material handler to weave through and avoid obstacles, providing conditions for placing materials for the ultra-thin flexible screen.

[0014] Preferably, the notch includes a side notch and a corner notch, wherein the corner notch and the side notch form an adsorption layer sequentially to push the ultra-thin flexible screen into the material trough. By using corner positioning, at least the side and the opposite ends are accurately positioned, so that the adsorption layer gradually formed on the side pushes downwards, and cooperates with the bottom material picker to gradually disengage to complete the pushing and leveling of the ultra-thin flexible screen.

[0015] In some specific embodiments, the side and corner notches are formed on the bottom surface of the ultra-thin flexible screen with negative pressure adsorption holes, and chamfers are formed at the top of the side and corner notches.

[0016] According to another specific embodiment and preferred aspect of the present invention, each material station further includes a top support rod located within the area enclosed by multiple material rods, with its top surface flush with the bottom surface of the material trough. There are multiple top support rods, arranged sequentially at intervals along the direction of flattening the ultra-thin flexible screen. The robotic arm can avoid the material rods and top support rods when placing material into the trough. Based on the further effective support of the top support rods, the quality of flattening and placing material into the ultra-thin flexible screen is further improved.

[0017] Preferably, multiple material rods are symmetrically arranged from both sides, with one top support rod corresponding to two material rods, and the two material rods are symmetrically arranged about their corresponding top support rods. This arrangement effectively allows for the movement of the material handler to avoid obstacles, facilitating the placement of material into basket A.

[0018] According to another specific embodiment and preferred aspect of the present invention, during the reversal process in step S2, the rotating platform performs station switching in a rotation cycle of 180°. Based on the interchange between workstations, material placement in basket A and material removal from basket B can be performed simultaneously, and the position can be interchanged every 180° rotation, without being limited by forward or reverse rotation.

[0019] Preferably, the rotating platform has two workstations: a basket A loading station and a basket B unloading station, with the number of material platforms on the basket A loading station and the basket B unloading station being equal. This ensures that the working cycles for basket A loading and basket B unloading are also equal, reducing necessary waiting time and thus improving basket handling efficiency.

[0020] In some specific implementations, basket A loading station has four loading platforms, two of which are fixed to a rotating platform, and the other two are movably mounted on the rotating platform to create a movement clearance, allowing the picking hand to insert and load materials along the length or width of the ultra-thin flexible screen. Basket B loading station also has four loading platforms, two of which are fixed to a rotating platform, and the other two are movably mounted on the rotating platform to create a movement clearance, allowing the robotic arm to insert and pick materials along the length or width of the ultra-thin flexible screen. In other words, the picking hand picks up four ultra-thin flexible screens at a time, and the robotic arm loads four ultra-thin flexible screens into the basket at a time.

[0021] Furthermore, in step S3, the robotic arm and the material handling hand have the same structure, and the direction in which the robotic arm inserts into the material platform is perpendicular to the direction in which the material handling hand inserts into the material platform, so as to complete the transfer of the ultra-thin flexible screen after a 90° reversal, and at the same time insert the ultra-thin flexible screen into the corresponding B basket. Here, based on the 90° reversal, not only is the basket turning of different reference sides of the long and short sides satisfied, but no additional rotating mechanism is required to achieve the required 90° reversal of the ultra-thin flexible screen (switching of long and short side positions). Therefore, it not only optimizes the structure, but also requires less space.

[0022] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: In the existing AB basket reversing basket system for ultra-thin flexible screens, during the movement of basket A, the ultra-thin flexible screens inevitably shift within the material compartment. This causes misalignment of the corners between multiple ultra-thin flexible screens when retrieving them from basket A, increasing the difficulty of transfer and placement, and significantly increasing the rate of corner damage caused by impacts during placement. Furthermore, during the transfer and placement process of ultra-thin flexible screens, due to their flexibility, if the entire flexible screen is directly dropped into the material tray without external force, its flexibility inevitably causes it to arch or bend. Therefore, there is a high risk of corner damage during the dropping process. Damage rate; Furthermore, the intermediate material placement step mainly considers the basket orientation of the ultra-thin flexible screen. For example, basket placement is based on the long side of the ultra-thin flexible screen (referred to as long-side basket placement) or the short side of the ultra-thin flexible screen (referred to as short-side basket placement). That is, when reversing the orientation of the long-side and short-side baskets, not only does the material tray need to rotate 90° to achieve position exchange, but it also cannot simultaneously perform material placement and retrieval of basket B. In other words, after rotating 90° to reverse the orientation, it is necessary to wait for the ultra-thin flexible screen on the material tray to be removed before rotating 90° to reset it, and then placing the ultra-thin flexible screen in basket A. Therefore, the operation process... The present invention addresses the shortcomings of existing technologies, such as complexity and low efficiency. It is based on a comprehensive design for the oblique loading, leveling, and reversing basket processing of ultra-thin flexible screens, cleverly solving these deficiencies. Using this processing technology, firstly, with one side and one of the front or back sides as a reference, the ultra-thin flexible screens in basket A are positioned at the same angle and with equal basket lengths. A first robot simultaneously picks up multiple ultra-thin flexible screens, and simultaneously adsorbs them from basket A to complete the material handling process. Secondly, with the two ends of the reference side facing each other and aligned, multiple ultra-thin flexible screens are adsorbed onto the first robot. The material handling hand then picks up the material and, based on the quantity picked up by the material handling hand, places each ultra-thin flexible screen onto the material table in sequence. During placement, the ultra-thin flexible screen on the upper part of the material handling hand is positioned above the material trough of the material table and is positioned with the reference side as the adsorption reference. Then, it gradually forms adsorption from the material trough to the opposite side of the reference side. At the same time, the material handling hand rotates relative to each other to make the ultra-thin flexible screen gradually detach from the material handling hand and fall into the material trough in sequence. The ultra-thin flexible screen is pushed flat by the gradual adsorption. In addition, two sets of material tables arranged on a dual-station rotating platform with interchangeable positions simultaneously perform A basket placement and B basket picking.Finally, based on the displacement of the material platform on the rotating platform to avoid the manipulator of the second robot, and with the direction of the manipulator's insertion into the material slot perpendicular to the direction of the picker's insertion into the material slot below, the thin flexible screens on multiple material platforms are sequentially adsorbed in the same direction and position. Then, maintaining the consistent direction of the manipulator's insertion into the material slot, the reversed ultra-thin flexible screens are inserted into the material compartment of basket B. Therefore, this invention, on the one hand, is based on the ultra-thin flexible screens in basket A being parallelly mounted at the same angle and with equal insertion lengths to maintain adsorption aligned from the reference side, and on the other hand, combines end-alignment to maintain the corner alignment of multiple ultra-thin flexible screens. Then, based on the material platform forming a first... The gradual disengagement of the robotic arm and subsequent adsorption process flattens the ultra-thin flexible screen from the reference side to the opposite side, reducing edge damage during transfer and placement, and preventing uneven placement. Furthermore, the dual-station switching maintains synchronization between A-basket placement and B-basket retrieval. The staggered arrangement of the workstations ensures vertical insertion and retrieval, allowing for reversing transfer and basket insertion of the ultra-thin flexible screen within a smaller space without the need for rotating the worktable. This not only meets the A / B basket reversal requirements but also simplifies the operation and increases efficiency. Attached Figure Description

[0029] like Figures 1 to 8 As shown, the processing equipment used in the oblique transfer, leveling and material placement and reversing basket processing of the ultra-thin flexible screen in this embodiment includes A basket material handling device 1, intermediate material placement device 2, and B basket material loading device 3.

[0030] Specifically, the A-basket material handling device 1 includes an A-basket feeding mechanism 10 and a first robot 11. The A-basket feeding mechanism 10 is used to fill the A-basket I loaded with ultra-thin flexible screens M into the material area. At the same time, it needs to perform alignment and positioning operations. That is, the A-basket feeding mechanism 10 includes a ring transmission chain 100, brackets 101 located on opposite sides of the material area, and a lifting component 102 for driving the brackets 101 to move up and down. The lifting component 102 lifts up and down at different heights so that the ultra-thin flexible screens M are based on one side and one side of the front and back sides. The A-basket I is placed at the same angle and with equal basket length, and the first robot 11 simultaneously picks up multiple ultra-thin flexible screens M.

[0031] In this example, basket A has a basket frame a, a support rod b, and a comb rod c. The support rod b has multiple support slots b1 arranged side by side, perpendicular to the length direction of the support rod b. The comb rod c is located on opposite sides of the support rod b. That is, a material grid is formed between the comb slots c1 corresponding to the support slots b1. Multiple material grids are formed along the length direction of the support rod b. At the same time, basket A has multiple rows of material grids, thereby increasing the loading capacity of basket A.

[0032] Specifically, there are multiple support rods b located between the two comb rods c (two are side-by-side in this example), and the support slots b1 are arranged in a one-to-one correspondence. Each ultra-thin flexible screen M is inserted into the multiple side-by-side support slots b1 from the reference side. Utilizing multi-point alignment to form aligned insertion on the reference side is more conducive to the parallelism of the ultra-thin flexible screens M in basket I. At the same time, two comb rods c form a group, with at least one group arranged in the depth direction of the material compartment. The number of groups is selected based on the size of the ultra-thin flexible screen to ensure that the ultra-thin flexible screen is placed obliquely in each material compartment in a parallel state. Based on the size of the ultra-thin flexible screen, all ultra-thin flexible screens can be inserted and positioned under the same reference, which not only reduces the probability of edge collisions later, but also facilitates the flattening and placement of the ultra-thin flexible screen. In this example, there are four groups of comb rods c, which are aligned vertically. At the same time, the distance between the comb rods c can also be adaptively adjusted according to the width of the ultra-thin flexible screen M.

[0033] The first robot 11 is a commonly used multi-axis motion robot. Its material handling hand 110 includes multiple parallel material shovels d, and these shovels d can be matched with corresponding material slots to pick up materials by parallel contact between the shovel surfaces and the ultra-thin flexible screen. This avoids damage to the edges and corners of the ultra-thin flexible screen during material handling. In this example, there are four material shovels d arranged at equal intervals, and each material shovel d forms a negative pressure cavity and an adsorption hole d1. Then, the ultra-thin flexible screen M is picked up based on the adsorption force formed by the negative pressure adsorption hole.

[0034] The intermediate material placement device 2 includes a aligning component 20 and an intermediate reversing component 21. The aligning component 20 aligns materials from opposite sides and includes aligning terminals 200 and a power component 201 that move in opposite directions. The intermediate reversing component 21 includes a rotating platform 210 with a rotation period of 180° and multiple material platforms 211 installed on the rotating platform 210. The multiple material platforms 211 are divided into two groups and correspond to the A basket material placement station and the B basket material removal station on the rotating platform 210, respectively.

[0035] The B basket loading device 3 includes a B basket receiving mechanism 30 and a second robot 31. The second robot 31 has the same structure as the first robot 11. After the robot arm 310 inserts the B basket II, the B basket receiving mechanism 30 performs the receiving and output of the B basket II. The B basket receiving mechanism 30 also adopts a conventional ring conveyor chain or other output (e.g., conveyor belt). In this example, the structure of the B basket II is the same as that of the A basket I.

[0036] In this example, the A basket loading station has four material platforms 211. Two of these platforms are fixed to the rotating platform 210, while the other two are movably mounted on the platform to create a movement clearance, allowing the picking hand 110 to insert materials along the length or width of the ultra-thin flexible screen M. The B basket loading station also has four material platforms 211, with two fixed to the rotating platform 210 and the other two movably mounted on it to create a movement clearance, allowing the robotic arm 310 of the B basket loading device 3 to insert and pick materials along the length or width of the ultra-thin flexible screen M. In other words, the picking hand picks up four ultra-thin flexible screens at a time, and the robotic arm inserts four screens into the basket at a time. In short, the number of material platforms at the A basket loading station and the B basket picking station is equal. This ensures that the working cycles for A basket loading and B basket picking are also equal, reducing necessary waiting time and thus improving basket handling efficiency.

[0037] The material platform 211 is formed by multiple material rods g1, each material rod g1 having a notch q at its top, and the multiple notches q are assembled to form a material trough. The surrounding material rods g1 facilitate the material handling personnel's movement and avoidance of obstacles, providing conditions for placing the ultra-thin flexible screen. Preferably, the notch q includes a side notch q1 and a corner notch q2, wherein the corner notch q2 and the side notch q1 successively form suction to push the ultra-thin flexible screen M into the material trough. The corner positioning ensures that at least the side and opposite ends are accurately positioned, allowing the gradually forming suction on the side to push downwards, and coordinating with the bottom material handling personnel to gradually disengage, thus completing the pushing and placing of the ultra-thin flexible screen. The formation of the side notch q1 and the corner notch q2 supports the formation of negative pressure suction holes q10 and q20 on the bottom surface of the ultra-thin flexible screen, and chamfers are formed at the top of the side notch and the corner notch. Each material platform 211 also includes a top support rod g2 located within the area enclosed by multiple material rods g1, with its top surface flush with the bottom surface of the material trough. There are multiple top support rods g2, arranged at intervals along the direction of the ultra-thin flexible screen M. The robotic arm 310 can avoid the material rods g1 and top support rods g2 when placing materials into the trough. The further effective support from the top support rods further improves the quality of the ultra-thin flexible screen's flattening and material placement. Multiple material rods g1 are symmetrically arranged from both sides, with one top support rod g2 corresponding to two material rods g1, and the two material rods g1 are symmetrically arranged about their corresponding top support rods g2. This arrangement effectively allows for the movement of the material handler to avoid obstacles, facilitating the placement of materials into basket A.

[0038] In summary, the implementation process of this embodiment is as follows: S1, the A-basket material retrieval step includes the A-basket filling process and the process of the first robot adsorbing the ultra-thin flexible screen from the A-basket. The ultra-thin flexible screen is positioned with one side and one side of the front or back as a reference, placing the ultra-thin flexible screens in the A-basket at the same angle and with equal insertion length. The first robot simultaneously picks up multiple ultra-thin flexible screens. The ultra-thin flexible screens at the same angle, loaded in the A-basket, move with the A-basket and enter the feeding area. Simultaneously, the A-basket is lifted from the front and back of the ultra-thin flexible screens corresponding to one side of the A-basket, and each ultra-thin flexible screen is placed parallel and obliquely in the material compartment of the A-basket. The equal insertion length is achieved by placing the A-basket horizontally, ensuring that the ultra-thin flexible screens in each material compartment are in the same working condition (here, the steps are sequential; note that the same angle adjustment must be performed first, followed by the same length adjustment). S2, the intermediate material placement step includes the material placement process and the reversing process. During the material placement process, firstly, multiple ultra-thin flexible screens are aligned and adsorbed onto the first robot's picking hand, with the two ends of the reference side facing each other. Secondly, based on the quantity of material picked up by the picking hand and the corresponding material platform, each ultra-thin flexible screen is placed onto the material platform in sequence. During the material placement, the ultra-thin flexible screens on the upper part of the picking hand are positioned above the material trough of the material platform and are positioned with the reference side as the adsorption reference. Then, adsorption is gradually formed from the material trough to the opposite side of the reference side. At the same time, the picking hand rotates relative to each other to make the ultra-thin flexible screens gradually detach from the picking hand and fall into the material trough in sequence. The ultra-thin flexible screens are pushed flat by the gradual adsorption. During the reversing process, two sets of material platforms arranged on a dual-station rotating platform with interchangeable positions simultaneously perform A basket material placement and B basket material removal. The rotating platform used rotates in 180° cycles to switch workstations. S3, the loading step of basket B includes the process of the second robot taking out the ultra-thin flexible screen from step S2 and inserting it into basket B, and the transfer process of basket B. In the process of inserting basket B, firstly, based on the displacement of the material platform on the rotating platform to avoid the manipulator of the second robot, and the direction of the manipulator inserting into the material slot is perpendicular to the direction of the material picker entering the material slot below, the ultra-thin flexible screens on multiple material platforms are sequentially adsorbed in the same direction and in the same position; secondly, keeping the manipulator inserted into the material slot in the same direction, the ultra-thin flexible screen after reversing is inserted into the material compartment of basket B.

[0039] Furthermore, in step S1, the ultra-thin flexible screen loaded in basket A moves with basket A and enters the feeding area. Simultaneously, basket A is lifted from the front and back sides corresponding to one side of basket A, and each ultra-thin flexible screen is placed parallel and obliquely in the material grid of basket A. In the aligning process of step S2, the ultra-thin flexible screen is mounted on the picking hand. At this time, the negative pressure disappears, and the aligning components move relative to each other for centering and alignment. Based on the horizontal state of the ultra-thin flexible screen, centering and alignment are performed again to make the positions of multiple ultra-thin flexible screens relatively aligned. In the picking process of step S3, the robot arm and the picking hand have the same structure, and the direction of the robot arm inserting into the material table is perpendicular to the direction of the picking hand inserting into the material table, so as to complete the transfer of the ultra-thin flexible screen after a 90° reversal, and at the same time insert the ultra-thin flexible screen into the corresponding material grid of basket B. Here, based on the 90° reversal, not only can the basket be tilted on different reference sides of the long and short sides, but no additional rotating mechanism is required to achieve the required 90° reversal (switching of long and short side positions) of the ultra-thin flexible screen. Therefore, it not only optimizes the structure, but also requires less space.

[0040] In summary, after adopting this processing technology, firstly, using one side and one of the front and back sides of the ultra-thin flexible screen as a reference, the ultra-thin flexible screens in basket A are positioned at the same angle and with equal basket lengths. The first robot simultaneously picks up multiple ultra-thin flexible screens, and simultaneously adsorbs ultra-thin flexible screens from basket A to complete the material handling process. Secondly, with the two ends of the reference side facing each other, multiple ultra-thin flexible screens are aligned and adsorbed onto the first robot's picking hand. Then, based on the quantity picked up by the picking hand and the corresponding material platform, each ultra-thin flexible screen is placed onto the material platform sequentially. During placement, the ultra-thin flexible screens on the upper part of the picking hand are positioned above the material trough on the material platform, and are positioned using the reference side as the adsorption reference. Then, they are moved from the trough towards the reference side. The opposite sides of the screen gradually form an adsorption, while the picker rotates relative to each other to allow the ultra-thin flexible screen to gradually detach from the picker and fall into the material tray in sequence. The ultra-thin flexible screen is pushed and placed by the gradual adsorption. In addition, two sets of material platforms arranged in interchangeable positions on a dual-station rotating platform simultaneously perform A basket placement and B basket retrieval. Finally, based on the displacement of the material platform on the rotating platform to avoid the manipulator of the second robot, and with the direction of the manipulator's insertion into the material tray perpendicular to the direction of the picker's insertion into the material tray, the ultra-thin flexible screens on multiple material platforms are adsorbed in the same direction and position in sequence. Then, keeping the manipulator's insertion into the material tray in the same direction, the ultra-thin flexible screen after reversal is inserted into the material compartment of the B basket. Therefore, this invention is based on ultra-thin The ultra-thin flexible screens in basket A are arranged in parallel at the same angle with equal basket lengths to maintain alignment and adsorption from the reference side. Simultaneously, end-alignment is used to ensure corner alignment of multiple ultra-thin flexible screens. Then, based on the sequential adsorption of the material platform and the gradual disengagement of the robotic arm, the ultra-thin flexible screens are pushed flat from the reference side to the opposite side. This not only reduces corner damage during transfer and placement but also avoids uneven placement. Furthermore, a dual-station switching mechanism maintains synchronization between basket A placement and basket B retrieval. The staggered placement of the material platforms in each station ensures vertical insertion and retrieval, thus enabling ultra-thin flexible screens to be installed in a smaller space without the need for rotating the material platform. The reversing and insertion of the flexible screen not only meets the reversing and inverting requirements of the AB baskets of the ultra-thin flexible screen, but also has a simple operation process and high efficiency. Thirdly, the bottom support is formed by the frame groove and the side support is formed by the comb groove, so that the ultra-thin flexible screen is relatively flat and inserted into the corresponding material grid, thereby maintaining the same benchmark for adsorption and material picking, thus improving the corner alignment of the ultra-thin flexible screen. At the same time, the alignment of the benchmark side by using multi-point alignment is more conducive to the parallelism of the ultra-thin flexible screen in the A basket. In addition, the selection is based on the size of the ultra-thin flexible screen, and all ultra-thin flexible screens can be inserted and positioned under the same benchmark, which not only reduces the probability of corner collisions in the later stage, but also makes it more conducive to the flattening and placement of the ultra-thin flexible screen.Fourthly, the material handling hand has multiple parallel shovels, and these shovels can be matched with corresponding material slots. The shovel surfaces are parallel to and adhere to the ultra-thin flexible screen to absorb and pick up the material, avoiding damage to the edges and corners of the ultra-thin flexible screen during the material picking process. Fifthly, based on the horizontal state of the ultra-thin flexible screen, it is then aligned and centered to ensure that the positions of multiple ultra-thin flexible screens are relatively aligned. At the same time, the surrounding material rods facilitate the material handling hand's movement and avoidance, providing conditions for placing the ultra-thin flexible screen. Then, corner positioning is adopted, ensuring that at least the side and opposite ends are accurately positioned. This allows for gradual adjustment on the side. The resulting adsorption pushes the material downwards, and the bottom material picker gradually disengages to complete the flattening and placement of the ultra-thin flexible screen. Sixthly, based on the further effective support of the top support rod, the quality of the flattening and placement of the ultra-thin flexible screen is further improved. Multiple material rods are symmetrically arranged from both sides, with one top support rod corresponding to two material rods, and the two material rods are symmetrically arranged about their corresponding top support rods. In this arrangement, the movement of the material picker is effectively avoided, facilitating the placement of material in basket A. Seventhly, during the reversal process in step S2, the rotating platform rotates in 180° cycles to switch workstations. Based on the interchange between workstations, placement in basket A and retrieval in basket B can be performed simultaneously, and the position can be interchanged every 180° rotation, without being limited by forward or reverse rotation. Simultaneously, the number of material platforms on the placement and retrieval workstations is equal, thus maintaining equal working cycles for placement and retrieval, reducing necessary waiting time, and improving basket-turning efficiency. In the eighth aspect, during the material handling process in step S3, the robotic arm and the material handling hand have the same structure, and the direction in which the robotic arm inserts into the material platform is perpendicular to the direction in which the material handling hand inserts into the material platform. This completes the transfer of the ultra-thin flexible screen after a 90° reversal, and simultaneously inserts the ultra-thin flexible screen into the corresponding B basket. Here, based on the 90° reversal, not only is the basket turning on different reference sides of the long and short sides satisfied, but no additional rotating mechanism is required to achieve the required 90° reversal of the ultra-thin flexible screen (switching of long and short side positions). Therefore, it not only optimizes the structure but also requires less space.
