Description

Technical Field

[0001] This invention belongs to the field of ultra-thin flexible screen processing technology, specifically relating to an ultra-thin flexible screen rotating basket device. Background Technology

[0002] In the processing of ultra-thin flexible screens, after completing one process, the ultra-thin flexible screen needs to be transferred from the current basket to the basket of the next process.

[0003] Currently, existing ultra-thin flexible screen basket turning equipment generally includes a feeding station, a transfer station, and a discharging station. The basket containing the ultra-thin flexible screen and the empty basket are moved to the feeding station and the discharging station, respectively. At the same time, in order to meet the processing direction requirements of the ultra-thin flexible screen in different processes, the placement direction of the ultra-thin flexible screen in the basket needs to be changed. For example, the robot arm picks up the ultra-thin flexible screen from the basket at the feeding station along the long side, and after transfer and positioning at the transfer station, it inserts the ultra-thin flexible screen into the basket at the discharging station along the short side, thus completing the basket turning of the ultra-thin flexible screen.

[0004] However, in actual production processes, existing technologies are prone to the following drawbacks:

[0005] 1. In the transposition and transfer of ultra-thin flexible screens, the robotic arm cannot guarantee that the ultra-thin flexible screens are aligned in the long or short direction when picking up multiple pieces. When unloading the ultra-thin flexible screens, the inaccurate position can easily lead to a high rate of corner damage.

[0006] 2. When the robotic arm picks up materials, it generally uses the long or short side of the ultra-thin flexible screen as the picking reference, so that the ultra-thin flexible screen maintains the same posture when rotating the basket. However, once it is necessary to rotate the basket by exchanging the long and short sides, there is interference in unloading the ultra-thin flexible screen, which makes it impossible for the ultra-thin flexible screen to be successfully reversed and transferred. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide an improved ultra-thin flexible screen rotating basket device.

[0008] To achieve the above objectives, the present invention adopts the following solution:

[0009] An ultra-thin flexible screen rotating basket device includes a basket frame, a feeding unit, a transfer unit, and a discharging unit. The basket frame has multiple placement areas arranged in an array. The feeding unit is used for shifting and feeding the basket frame. The transfer unit includes a transfer mechanism and a robotic arm. The discharging unit is used for shifting and discharging the basket frame. Multiple ultra-thin flexible screens are aligned from the bottom edge and the side edge abutting the reference point within the placement area, with one side of the placement area as a reference. The transfer mechanism includes a reversing platform and multiple support seats disposed on the reversing platform. Each support seat includes multiple support rods and an adsorption element. The top of each support rod forms a notch, which includes an abutting surface and a bearing surface. The adsorption element is shaped from the bearing surface. The system forms an adsorption structure, with multiple contact surfaces and bearing surfaces spliced ​​together to form a bearing space. Each contact surface forms a grid along the long and / or short side of the ultra-thin flexible screen. The ultra-thin flexible screen abuts against the grid from the side and / or corner. As the robot gradually detaches, the adsorption components arranged sequentially along the long or short side of the ultra-thin flexible screen form an adsorption structure to flatten and position the ultra-thin flexible screen within the bearing space. Some of the bearing seats are shifted relative to the reversing platform to allow the robot to avoid picking up and placing materials. The multiple bearing seats are divided into a transfer feeding group and a transfer discharging group based on the number of materials picked up by the robot. The positions of the transfer feeding group and the transfer discharging group are interchanged every 180° rotation of the reversing platform.

[0010] According to a specific embodiment and preferred aspect of the present invention, multiple carriers in the transfer feeding group and the transfer discharging group are arranged side by side at intervals along the long side of the ultra-thin flexible screen, and in the transfer feeding group and the transfer discharging group, every two adjacent carriers can move relative to each other in the short side direction of the ultra-thin flexible screen to be misaligned or aligned. Here, misalignment is formed based on the relative movement of adjacent carriers to avoid movement interference when picking up and placing materials one by one along the long side direction, while alignment facilitates fast and accurate picking and placing of materials based on the same reference when picking up and placing materials in the short side direction.

[0011] Preferably, the transfer feeding group and the transfer discharging group are each provided with four bearing seats, wherein the two bearing seats located at both ends of the long side direction are fixed on the reversing platform, and the two bearing seats located in the middle can reciprocate along the short side direction respectively.

[0012] According to another specific embodiment and preferred aspect of the present invention, in each support base, multiple support rods are arranged side by side at intervals along the long and short sides around the ultra-thin flexible screen.

[0013] Preferably, the multiple notches are divided into multiple first notches and multiple second notches. During flat positioning, the ultra-thin flexible screen is positioned at each first notch from the corner and at each second notch from the side. This ensures omnidirectional support and positioning of the ultra-thin flexible screen to reduce deformation rate.

[0014] Preferably, each first notch has two contact surfaces that are perpendicular to each other, and the ultra-thin flexible screen contacts the two contact surfaces from the two sides of the corner.

[0015] Specifically, in each of the first notches, the two contact surfaces are spaced apart. This prevents the apex of the corner from directly contacting the contact surface and causing damage during the contact positioning process.

[0016] Preferably, each notch further includes a motion guide surface, wherein the motion guide surface extends inward from top to bottom and is connected to the top edge of the contact surface; and / or, the adsorption member has a plurality of adsorption holes arranged side by side and spaced apart along the long side of the ultra-thin flexible screen on each bearing surface.

[0017] According to another specific embodiment and preferred aspect of the invention, the support base further includes multiple support rods disposed between multiple support rods. As the ultra-thin flexible screen is laid flat and positioned within the support space, the ultra-thin flexible screen is simultaneously supported on the multiple support rods. Here, the central part of the ultra-thin flexible screen is supported to prevent the central part of the screen from collapsing and deforming after being removed from the robotic arm.

[0018] Preferably, each support rod forms a support surface from the top, wherein each support surface is flush with the bearing surface; and / or, multiple support rods are arranged side by side at intervals along the long side of the ultra-thin flexible screen.

[0019] According to another specific embodiment and preferred aspect of the invention, the robotic arm has a plurality of picking and placing ends spaced apart along the thickness direction of the ultra-thin flexible screen, wherein each pair of adjacent picking and placing ends forms a receiving space for a single ultra-thin flexible screen, and the plurality of picking and placing ends can be sequentially inserted into each bearing space and picking and placing materials one by one from bottom to top or from top to bottom. Here, the plurality of picking and placing ends are stacked to reduce the space occupied and facilitate the picking and placing of materials on the basket or bearing seat.

[0020] Preferably, each pick-up and drop-off end is U-shaped, and the two arms of each pick-up and drop-off end are arranged side by side and spaced apart along the short side of the ultra-thin flexible screen. Each arm is provided with multiple negative pressure suction holes arranged side by side and spaced apart along the long side of the ultra-thin flexible screen. Here, the structure is simple and facilitates the implementation of pick-up and drop-off movements; at the same time, it can achieve adsorption of the ultra-thin flexible screen in either the long or short side direction, which is highly flexible.

[0021] Preferably, during placement, each pick-up and drop-off end can rotate up and down around the horizontal center line so that the pick-up and drop-off end gradually detaches from the ultra-thin flexible screen from the end closest to the grid to the other end. Here, based on the ultra-thin flexible screen abutting against the grid, the pick-up and drop-off ends gradually detach from the ultra-thin flexible screen by rotating up and down, thus achieving cooperation with the sequential adsorption of the adsorption component to gradually flatten the ultra-thin flexible screen and place the material onto the bearing surface. This minimizes interference with the process of the ultra-thin flexible screen adhering to the bearing surface and further improves placement accuracy.

[0022] According to another specific embodiment and preferred aspect of the invention, the transfer mechanism further includes a aligning power unit disposed on one side of the reversing platform, wherein the aligning power unit has an aligning space capable of retracting or expanding along the bottom edge direction. A robotic arm retrieves multiple ultra-thin flexible screens from the basket and inserts them into the aligning space, which then retracts to align the multiple ultra-thin flexible screens with its center line as a reference. This ensures that the multiple ultra-thin flexible screens are aligned and centered synchronously, improving placement accuracy on the support.

[0023] Preferably, the alignment power unit includes a first and a second set of striking rods spaced apart on both sides to form an alignment space, and a power component that drives the first and second sets of striking rods to move towards or away from each other. The first and second sets of striking rods each have multiple striking rods arranged side-by-side at intervals along the corresponding sides of the ultra-thin flexible screen. This design is simple and easy to install and implement.

[0024] According to another specific embodiment and preferred aspect of the present invention, the basket frame is provided with multiple bottom rods arranged side by side at intervals, and side rods disposed above each bottom rod. Each placement area includes multiple first placement slots arranged horizontally side by side at intervals on the bottom rods, and second placement slots disposed on the side rods and vertically aligned with the first placement slots. Each ultra-thin flexible screen is inserted into each of the first placement slots from its bottom edge and leans against the corresponding second placement slot from one side. Here, based on the leaning positioning of the ultra-thin flexible screen, the contact between the screen and the basket frame is reduced, lowering the probability of contact during material handling.

[0025] In addition, the feeding unit includes a feeding conveyor line forming a feeding station at one end, and an auxiliary power unit for driving the feeding station to move up and down and tilt. As the basket moves along the feeding conveyor line to the feeding station, the auxiliary power unit drives the feeding station to rise, causing the basket to detach from the feeding conveyor line and tilt. Each ultra-thin flexible screen then deflects and tilts in the same direction within its corresponding placement area. As the auxiliary power unit drives the basket to descend back to the feeding conveyor line and return to a horizontal position, each ultra-thin flexible screen maintains alignment of its top and bottom edges. Here, based on the basket's height-adjustable and tiltable design, it is ensured that during material retrieval, all ultra-thin flexible screens in the basket are oriented in the same direction and have their top and bottom edges flush, maintaining the same reference point for precise material adsorption and retrieval by the robotic arm.

[0026] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0027] In existing technologies for transpositioning and reloading ultra-thin flexible screens, the robotic arm cannot guarantee that the ultra-thin flexible screens will remain aligned along their long or short sides when picking up multiple pieces. This leads to a high rate of corner damage during unloading due to inaccurate positioning. The robotic arm typically uses the long or short side of the ultra-thin flexible screen as a picking reference to keep the screen in the same orientation during basket rotation. However, when basket rotation requires swapping the long and short sides, interference during unloading can prevent the ultra-thin flexible screens from being successfully transposed and reloaded. This application presents a comprehensive structural design for the ultra-thin flexible screen rotating basket device, cleverly addressing the shortcomings and defects of existing technologies. Using this device, the feeding unit moves and feeds baskets containing ultra-thin flexible screens from each placement area, aligning each screen with its bottom edge and the side edge against the reference point within the placement area. A robotic arm then removes multiple ultra-thin flexible screens from the baskets and places them onto the corresponding carriers in the transfer feeding group. The carrier space formed by the placement of the ultra-thin flexible screens on each carrier creates a support space... During the process, as the robotic arm gradually detaches, the adsorption components arranged sequentially along the long or short sides of the ultra-thin flexible screen form an adsorption structure to flatten and position the ultra-thin flexible screen within the carrying space. Every 180° rotation of the reversing platform, the positions of the transfer feeding group and the transfer discharging group are interchanged. Then, the robotic arm removes the ultra-thin flexible screens from each carrier and inserts them into the empty basket. During the sequential picking and placing of materials between multiple carriers, some carriers are displaced relative to the reversing platform to allow the robotic arm to avoid them. Finally, the discharging unit moves the basket to discharge the materials. Therefore, compared with the prior art, the present invention, on the one hand, is based on the ultra-thin flexible screen being aligned with one side of the placement area and mounted in the basket frame for precise material picking by the robotic arm. During the transfer process, as the robotic arm gradually detaches, the ultra-thin flexible screen is flattened and positioned on the carrier by the sequential adsorption of the side or corner of the grid and the adsorption component in the long or short direction. This significantly improves the positional accuracy of the screen unloading, reduces the damage rate of the screen corners caused by misalignment, and meets the high stability requirements of the transfer process for ultra-thin flexible screens. On the other hand, the displacement of some carriers relative to the reversing platform among multiple carriers allows the robotic arm to avoid interference during material picking and placing of multiple ultra-thin flexible screens. The 180° rotation of the reversing platform ensures smooth basket rotation for long and short side exchange of the screen. Attached Figure Description

[0044] like Figures 1 to 6 As shown, the ultra-thin flexible screen rotating basket device of this embodiment includes a basket frame 1, a feeding unit 2, a transfer unit 3, and a discharging unit 4.

[0045] Specifically, there are two basket frames 1, corresponding to the feeding unit 2 and the discharging unit 4. Each basket frame 1 has multiple placement areas q arranged in an array. Multiple ultra-thin flexible screens P can be placed one-to-one in each of the placement areas q. The basket frame 1 has multiple bottom rods 10 arranged side by side at intervals, and side rods 11 arranged above each bottom rod 10. Each placement area q includes multiple first placement slots q1 arranged horizontally side by side at intervals on the bottom rods 10, and second placement slots q2 arranged on the side rods 11 and aligned vertically with the first placement slots q1. Each ultra-thin flexible screen P is inserted into each of the first placement slots q1 from the bottom edge and leans against the corresponding second placement slot q2 from one side. Here, based on the leaning positioning of the ultra-thin flexible screen, the contact between the screen and the basket frame is reduced, and the probability of contact during material handling is lowered.

[0046] For ease of implementation, both the base rod 10 and the side rods 11 are horizontally arranged. Multiple side rods 11 are arranged vertically at intervals, and the second placement slot q2 is located on one side of each side rod 11 and is a horizontal U-shaped slot. The second placement slots at different heights are used to match ultra-thin flexible screens of different lengths or widths, and also provide multi-point support to the screen to prevent deformation when tilted. It should be noted that in this embodiment, during feeding, the ultra-thin flexible screen is inserted into the corresponding basket along its long side; during discharging, the ultra-thin flexible screen is inserted into the corresponding basket along its short side.

[0047] In this example, the feeding unit 2 includes a feeding conveyor line 20 forming a feeding station w1 at one end, and an auxiliary power unit 21 for driving the feeding station w1 to move up and down and tilt. As the basket 1 moves along the feeding conveyor line 20 to the feeding station w1, the auxiliary power unit 21 drives the feeding station w1 to rise, causing the basket 1 to disengage from the feeding conveyor line 20 and tilt to one side. Each ultra-thin flexible screen then deflects and tilts in the same direction within its corresponding placement area q. As the auxiliary power unit 21 drives the basket 1 down to the feeding conveyor line 20 and returns it to a horizontal position, the top and bottom edges of each ultra-thin flexible screen remain aligned. That is, based on the ultra-thin flexible screen being tilted within the placement area q, the tilting of the basket 1 keeps the tilting direction of the ultra-thin flexible screens consistent, and when the basket returns to a horizontal position, the bottom and top edges of each ultra-thin flexible screen remain aligned. Here, based on the design of the basket frame being height-adjustable and tiltable, it is ensured that all the ultra-thin flexible screens in the basket frame are aligned in direction and have their top and bottom edges flush during material retrieval, so as to facilitate the robot arm to accurately pick up materials while maintaining the same benchmark.

[0048] In some specific embodiments, the feeding conveyor line 20 adopts a horizontal conveyor belt; the auxiliary power unit 21 can be any conventional power unit capable of lifting and deflecting motion. For example, in this embodiment, the auxiliary power unit 21 adopts multiple cylinders and is connected to the opposite sides of the feeding station w1. Based on the driving cooperation of multiple cylinders, the feeding station w1 can move up and down and deflect around the horizontal center line located on one side of the feeding station w1.

[0049] In this example, the transfer unit 3 includes a transfer mechanism 30 and a robotic arm 31. The transfer mechanism 30 includes a reversing platform 300, multiple support seats 301 mounted on the reversing platform 300, and a aligning power unit 302 mounted on one side of the reversing platform 300. Each support seat 301 includes multiple support rods a0 and an adsorption element a1. The top of each support rod a0 forms a notch c, which includes a contact surface m0 and a support surface m1. The adsorption element a1 forms an adsorption from the support surface m1. Multiple contact surfaces m0 and support surfaces m1 are spliced ​​together to form a support space. Each contact surface m0 is along the long side and / or short side of the ultra-thin flexible screen. A grid is formed along the side, and the ultra-thin flexible screen abuts against the grid from the side and / or corner. As the robot arm 31 gradually detaches, the adsorption components a1 arranged sequentially along the long or short side of the ultra-thin flexible screen form an adsorption to flatten and position the ultra-thin flexible screen within the bearing space. Some of the multiple bearing seats 301 are displaced relative to the reversing platform 300 to allow the robot arm 31 to pick up and place materials to avoid them. The multiple bearing seats 301 are divided into a transfer feeding group z1 and a transfer discharging group z2 based on the number of materials picked up by the robot arm 31. Every time the reversing platform rotates 180°, the positions of the transfer feeding group z1 and the transfer discharging group z2 are interchanged.

[0050] In some specific embodiments, the reversing platform 300 is horizontally positioned, and a drive motor is connected to the bottom of the reversing platform 300 to achieve 180° rotation around the vertical centerline.

[0051] To further facilitate implementation, multiple carrier seats 301 in the transfer feeding group and transfer discharging group are arranged side-by-side at intervals along the long side of the ultra-thin flexible screen. Furthermore, in both groups, adjacent carrier seats 301 can move relative to each other along the short side of the ultra-thin flexible screen to achieve misalignment or alignment. Here, misalignment is achieved based on the relative movement of adjacent carrier seats to avoid motion interference when picking up and placing materials one by one along the long side. Simultaneously, alignment facilitates rapid and accurate picking and placing of materials based on the same reference when picking up and placing materials along the short side.

[0052] In some specific embodiments, the transfer feeding group and the transfer discharging group are respectively provided with four bearing seats 301, of which the two bearing seats 301 located at both ends of the long side direction are fixed on the reversing platform 300, and the two bearing seats 301 located in the middle can reciprocate along the short side direction by means of telescopic cylinders.

[0053] Meanwhile, in each support base 301, multiple support rods a0 are arranged side-by-side at intervals around the ultra-thin flexible screen along its long and short sides; multiple notches c are divided into multiple first notches c1 and multiple second notches c2, wherein the ultra-thin flexible screen P is positioned at each first notch c1 from the corner and at each second notch c2 from both sides along its long sides. This ensures omnidirectional support and positioning of the ultra-thin flexible screen, thereby reducing the deformation rate.

[0054] In each first notch c1, there are two abutting surfaces m0 arranged perpendicularly to each other, with a gap between them. The ultra-thin flexible screen P abuts against the two abutting surfaces m0 from both sides of the corner (i.e., the short and long sides corresponding to the corner). Here, when forming the abutting positioning, the apex of the corner can be prevented from directly contacting the abutting surfaces and causing damage. In some other specific embodiments, the bearing space can also be set to be larger than the area of ​​the ultra-thin flexible screen P. Therefore, during positioning, the ultra-thin flexible screen P abuts against the first notch c1 and multiple second notches c2 on the corresponding sides from any corner and side to reduce the risk of scratch damage.

[0055] Each notch c also includes a motion guide surface m2, wherein the motion guide surface m2 extends inward from top to bottom and is connected to the top edge of the contact surface m0.

[0056] There are multiple adsorption components a1, each corresponding to one of the multiple support seats 301. In this embodiment, the adsorption components a1 are vacuum adsorbed. Each adsorption component a1 has multiple adsorption holes a10 arranged side by side and spaced apart along the long side of the ultra-thin flexible screen P on each support surface m1. Therefore, in this embodiment, the ultra-thin flexible screen is positioned in the first notch based on the corner of one end. As the robot gradually detaches and the multiple adsorption components arranged along the long side are adsorbed in sequence, the ultra-thin flexible screen automatically and gradually flattens and fits against the support surface, and is positioned within the support space.

[0057] To further facilitate implementation, the support base 301 also includes multiple support rods a2 disposed between the multiple support rods a0. As the ultra-thin flexible screen is laid flat and positioned within the support space, the ultra-thin flexible screen is simultaneously supported on the multiple support rods a2. Here, the central part of the ultra-thin flexible screen is supported to prevent the central part of the screen from collapsing and deforming after being removed from the robotic arm.

[0058] In some specific embodiments, each support rod a2 forms a support surface m3 from the top, wherein each support surface m3 is flush with the bearing surface m1; multiple support rods a2 are distributed side by side at intervals along the long side of the ultra-thin flexible screen.

[0059] In this example, the alignment power unit 302 has an alignment space that can retract or expand along the bottom edge direction (in this embodiment, i.e., the short side direction of the ultra-thin flexible screen). The robotic arm 31 takes out multiple ultra-thin flexible screens from the basket 1 and inserts them into the alignment space. The alignment space then retracts to align the multiple ultra-thin flexible screens with the center line of the alignment space as a reference. Here, it is ensured that the multiple ultra-thin flexible screens are aligned and centered synchronously, improving the placement accuracy on the support.

[0060] In some specific embodiments, the alignment power unit 302 includes a first pair of levers b1 and a second pair of levers b2 spaced apart on both sides to form an alignment space, and a rodless cylinder b3 that drives the first pair of levers b1 and the second pair of levers b2 to move towards or away from each other. The first pair of levers b1 and the second pair of levers b2 are each provided with multiple levers g arranged side-by-side and spaced apart along the corresponding sides of the ultra-thin flexible screen. That is, in this embodiment, the robotic arm removes multiple ultra-thin flexible screens from the basket, first aligns the ultra-thin flexible screens in the short-side direction within the alignment space, and then the robotic arm transfers the aligned ultra-thin flexible screens to the support base.

[0061] In this example, the robotic arm 31 has multiple picking and placing ends d spaced apart along the thickness direction of the ultra-thin flexible screen. Each pair of adjacent picking and placing ends d forms a receiving space for a single ultra-thin flexible screen. The multiple picking and placing ends d can be inserted sequentially into each carrying space and pick up and place materials one by one from bottom to top or from top to bottom. Here, the multiple picking and placing ends are stacked to reduce the space occupied and facilitate the picking and placing of materials on the basket or carrier.

[0062] In some specific embodiments, the robotic arm 31 employs an existing multi-axis motion robot to drive the pick-and-place end d to perform multi-directional movements to complete the reversing and transfer motion of the ultra-thin flexible screen. Each pick-and-place end d is U-shaped to allow insertion into the carrying space along the long or short side for picking and placing materials. Two arms of each pick-and-place end d are arranged side-by-side and spaced apart along the short side of the ultra-thin flexible screen, and each arm d is provided with multiple negative pressure suction holes d0 arranged side-by-side and spaced apart along the long side of the ultra-thin flexible screen. This design is simple and facilitates the implementation of the pick-and-place motion; simultaneously, it enables adsorption of the ultra-thin flexible screen in both the long and short side directions, offering high flexibility.

[0063] In particular, during placement, each pick-up and place end d can rotate up and down around the horizontal center line, allowing it to gradually detach from the ultra-thin flexible screen from the end closest to the grid towards the other. Here, based on the ultra-thin flexible screen abutting against the grid, the gradual detachment of the pick-up and place ends from the screen through rotation achieves a cooperative effect with the sequential adsorption of the adsorption components, gradually flattening the ultra-thin flexible screen and placing it onto the support surface. This minimizes interference with the process of the ultra-thin flexible screen adhering to the support surface, further improving placement accuracy. It should be noted that the rotation angle of the pick-up and place ends d is very small, and the spacing between the upper and lower pick-up and place ends does not cause interference with the placement of the ultra-thin flexible screen.

[0064] To increase the efficiency of the rotating basket, this embodiment uses two sets of robotic arms 31, which are arranged between the feeding unit 2 and the intermediate feeding group, and between the intermediate discharging group and the discharging unit 4, respectively, so as to drive their respective picking and placing ends d to pick and place materials along the long side and short side of the ultra-thin flexible screen.

[0065] In addition, the discharge unit 4 includes a discharge transmission line 40 that forms a discharge station w2 from one end. An empty basket is placed at the discharge station w2 to collect the ultra-thin flexible screen that is being transferred and rotated. When the basket is full, the basket is output by the discharge transmission line 40.

[0066] In summary, by employing this ultra-thin flexible screen rotating basket device, the feeding unit moves and feeds the baskets containing ultra-thin flexible screens in each placement area, ensuring that each ultra-thin flexible screen is aligned with its bottom edge and the side edge abutting the reference point within the placement area. A robotic arm then removes multiple ultra-thin flexible screens from the baskets and places them onto the corresponding carriers in the transfer feeding group. As the ultra-thin flexible screens are placed within the carrier space formed by the carriers, the screens gradually detach from the robotic arm, resulting in a smoother and more flexible surface. The adsorption components arranged sequentially along the long or short side of the flexible screen form an adsorption structure to flatten and position the ultra-thin flexible screen within the carrying space. Every 180° rotation of the reversing platform, the positions of the transfer feeding group and the transfer discharging group are interchanged. Then, the robotic arm removes the ultra-thin flexible screens from each carrier and inserts them into an empty basket. During the sequential picking and placing of materials between multiple carriers, some carriers are displaced relative to the reversing platform to allow the robotic arm to avoid them. Finally, the discharging unit discharges the displaced material from the basket. Therefore, compared with the prior art, this invention, on the one hand, is based on the ultra-thin flexible screen being aligned and mounted in the basket frame with one side of the placement area as a reference for precise material picking by the robotic arm. During the transfer process, as the robotic arm gradually detaches, the ultra-thin flexible screen is flattened and positioned on the carrier by the sequential adsorption of the side or corner of the grid and the adsorption component in the long or short direction, significantly improving the positional accuracy of screen unloading and reducing the damage rate of screen corners caused by misalignment, thus meeting the high stability requirements of the transfer process for ultra-thin flexible screens. On the other hand, based on the displacement of some carriers relative to the reversing platform, the robotic arm avoids material handling, effectively reducing interference between multiple ultra-thin flexible screens during material handling, and the reversing platform 1... The 80° rotation switching ensures smooth basket rotation for switching between long and short sides of the screen; thirdly, the relative movement of adjacent support seats creates misalignment to avoid motion interference when picking up and placing materials one by one along the long side, while alignment facilitates quick and accurate picking and placing of materials along the short side based on the same reference; fourthly, it ensures that multiple ultra-thin flexible screens are synchronously aligned and centered, improving placement accuracy on the support seat; fifthly, the tilted positioning of the ultra-thin flexible screens reduces contact between the screen and the basket frame, lowering the probability of collision during picking and placing; and the basket frame's height-adjustable and tiltable design ensures that all ultra-thin flexible screens in the basket frame are aligned in direction and have their top and bottom edges flush during picking, facilitating precise picking by the robotic arm.
