Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and more particularly to a flexible screen laser cutting system. Background Technology

[0002] Flexible screens, also known as flexible displays, are display devices based on flexible OLED technology. They are manufactured using flexible substrates. OLEDs, also known as organic light-emitting diodes, are driven by voltage. Electrons are injected into the cathode and holes are injected into the anode. The electrons and holes migrate to the light-emitting layer through the electron transport layer and hole transport layer, respectively. Finally, they recombine in the light-emitting layer to form excitons. When de-excited, they release energy in the form of photons, thereby producing visible light. This is a self-emissive display technology based on organic materials, which can achieve pixel-level independent light emission without a backlight. When existing laser cutting equipment cuts flexible screens, the operator needs to first place the flexible screen to be cut on a carrier plate. Then, the carrier plate moves the flexible screen to be cut under the laser cutting head, and the laser cutting head cuts the flexible screen. After the cutting is completed, the carrier plate removes the flexible screen from under the cutting head, and the operator manually removes the cut flexible screen from the carrier plate and then puts the flexible screen to be cut back on. This method is cumbersome and time-consuming, reducing processing efficiency. Moreover, during the cutting process, a large amount of dust and waste film easily adheres to the surface of the flexible screen, which cannot be cleaned and removed in time, affecting the subsequent processing quality of the flexible screen.

Detailed Implementation

[0032] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] like Figures 1 to 15As shown, a flexible screen laser cutting system of the present invention includes a base 1, wherein the base 1 is provided with a feeding mechanism 2, a cutting mechanism 3 used in conjunction with the feeding mechanism 2, and a unloading mechanism 4 used in conjunction with the cutting mechanism 3. The cutting mechanism 3 includes a feeding device 31 and a positioning device 32, a cutting device 33, a waste removal device 34, a cleaning device 35, and a flipping device 36 arranged sequentially according to the conveying direction of the feeding device 31. The feeding mechanism 2 is used to transfer the flexible screen to the feeding device 31. The positioning device 32 is used to visually position the flexible screen conveyed by the feeding device 31 so that the cutting device 33 can cut and process the shape of the flexible screen. The waste removal device 34 is used to peel off the waste edge film generated during cutting from the flexible screen. The cleaning device 35 is used to clean the surface of the flexible screen. The flipping device 36 is used to flip and switch the flexible screen conveyed by the feeding device 31 between the front and back sides. The unloading mechanism 4 is used to remove the flexible screen after cleaning.

[0035] During operation, the flexible screen is picked up by the feeding mechanism 2 and placed on the feeding device 31. Since the feeding device 31 is arranged along the length of the base 1, the flexible screen is conveyed by the feeding device 31 and sequentially passes through the positioning device 32, cutting device 33, waste removal device 34, cleaning device 35, and flipping device 36. First, the flexible screen reaches the positioning device 32 via the feeding device 31. The positioning device 32 performs visual positioning of the flexible screen, and then, with the help of an external robotic arm, accurately captures and adjusts the positioning points on the front of the flexible screen, thus facilitating the cutting device 33 to perform the corresponding cutting processing on the front of the flexible screen after the position adjustment. Next, the flexible screen reaches the waste removal device 34 via the feeding device 31, and the waste removal device 34... After cutting, the waste edge film is picked up and carried away, while the cleaning device 35 cleans the surface of the flexible screen. Finally, the flexible screen is conveyed by the feeding device 31 to the flipping device 36, which flips the front of the flexible screen to the back. Then, the feeding device 31 carries the back of the flexible screen back to the cleaning device 35, where the cleaning device 35 performs the same cleaning process on the back of the flexible screen. This completes a series of processes for positioning, cutting, removing waste edge film, and double-sided cleaning of the flexible screen. Using an assembly line processing mode, through division of labor and continuous operation, unnecessary waiting and downtime are reduced, significantly improving the processing efficiency of flexible screens per unit time, shortening the production cycle, reducing labor input, and resulting in a compact equipment layout with a small footprint. This invention automates the picking and placing of flexible screens through the loading mechanism 2 and unloading mechanism 4, removes waste edge film through the waste removal device 34, and cleans the surface of the flexible screen with the cleaning device 35. The entire process is unmanned, improving the processing quality and efficiency of flexible screens.

[0036] In this embodiment, the base 1 is provided with a first upright 11. The waste discharge device 34 and the cleaning device 35 are disposed on one side of the first upright 11. The waste discharge device 34 includes a first movable seat 341, a pickup component 342 disposed on the first movable seat 341, a first Z-axis drive device 343 for driving the first movable seat 341 to move along the Z-axis direction of the first upright 11, and a first X-axis drive device 344 for driving the first Z-axis drive device 343 to move along the X-axis direction of the first upright 11. The pickup component 342 includes a base 3421, a fixing block 3422 disposed on the base 3421, a first movable seat 3423 movably disposed on the base 3421, and a first X-axis drive device 344 drivenly connected to the first movable seat 3423. The device includes a lifting cylinder 3424 and a movable block 3425 rotatably mounted on a first movable seat 3423. The base 3421 is connected to the first movable seat 341. A first hinge shaft 3426 is provided at the connection between the first movable seat 3423 and the movable block 3425. A second hinge shaft 3427 is provided at the connection between the base 3421 and the movable block 3425. The movable block 3425 abuts against a fixed block 3422. The cleaning device 35 includes a cleaning brush 351 and a second lifting cylinder 352 drivenly connected to the cleaning brush 351. The second lifting cylinder 352 is mounted on a first upright 11 and drives the cleaning brush 351 to move up and down relative to the first upright 11.

[0037] Specifically, the first Z-axis drive device 343 drives the pickup assembly 342 to move up and down along the Z-axis of the first stand 11 via the first movable seat 341, and then drives the first Z-axis drive device 343 to move left and right along the X-axis of the first stand 11 via the first X-axis drive device 344, thereby expanding the range of motion. The first lifting cylinder 3424 is mounted on the base 3421, and the output end of the first lifting cylinder 3424 is connected to the first movable seat 3423. When the first lifting cylinder 3424 drives the movable block 3425 to move downward via the first movable seat 3423, the movable block 3425 moves around the first hinge axis 3426 and the second hinge axis respectively. Rotate 3427 until the movable block 3425 and the fixed block 3422 abut and clamp each other, thereby using the movable block 3425 and the fixed block 3422 to clamp the waste edge film together; when the first lifting cylinder 3424 drives the movable block 3425 to move upward through the first moving seat 3423, the movable block 3425 rotates around the first hinge shaft 3426 and the second hinge shaft 3427 respectively, until the movable block 3425 and the fixed block 3422 separate from each other, thereby using the movable block 3425 and the fixed block 3422 to release and discharge the waste edge film. The waste edge film is quickly peeled off and removed by clamping, with high waste discharge efficiency, so as not to affect the subsequent normal processing process. The second lifting cylinder 352 drives the cleaning brush 351 to move up and down relative to the first support 11. The cleaning brush 351 cleans the surface of the flexible screen after the waste edge film has been removed, effectively removing dust and residual waste to ensure good cleanliness. Preferably, four second lifting cylinders 352 are provided, and the four second lifting cylinders 352 are arranged at intervals along the length of the base 1 to increase the cleaning range. Among them, the first X-axis drive device 344 and the first Z-axis drive device 343 are both existing linear modules, and their specific structural composition and working principle will not be described in detail here.

[0038] The flipping device 36 of this embodiment is disposed on the other side of the first stand 11. The flipping device 36 includes a second movable seat 361, a second Z-axis drive device 362 for driving the second movable seat 361 to move along the Z-axis direction of the first stand 11, a second X-axis drive device 363 for driving the second Z-axis drive device 362 to move along the X-axis direction of the first stand 11, a first rotary cylinder 364 and a second rotary cylinder 365 disposed on the second movable seat 361, a first flipping frame 366 driven and connected to the first rotary cylinder 364, a first vacuum suction head 367 disposed on the first flipping frame 366, a second flipping frame 368 driven and connected to the second rotary cylinder 365, and a second vacuum suction head 369 disposed on the second flipping frame 368. The first rotary cylinder 364 and the second rotary cylinder 365 are disposed at intervals.

[0039] Specifically, the second Z-axis drive device 362 drives the first rotary cylinder 364 and the second rotary cylinder 365 to move up and down along the Z-axis direction of the first stand 11 via the second movable seat 361. Then, the second X-axis drive device 363 drives the second Z-axis drive device 362 to move left and right along the X-axis direction of the first stand 11, expanding the range of movement. When the first rotary cylinder 364 moves closer to the flexible screen, the first vacuum suction head 367 is aligned with the front of the flexible screen. The first rotary cylinder 364 drives the first vacuum suction head 367 to rotate upward 90 degrees via the first flipping frame 366, flipping the originally horizontally placed flexible screen to a vertically placed position. In the next step, the second vacuum suction head 369 aligns with the back of the flexible screen. Simultaneously, the first vacuum suction head 367 pauses its suction action. The first rotary cylinder 364, through the first flipping frame 366, drives the first vacuum suction head 367 downwards and away from the flexible screen. The second rotary cylinder 365, through the second flipping frame 368, drives the second vacuum suction head 369 downwards by 90 degrees, flipping the vertically placed flexible screen to a horizontal position. This achieves the flipping of the flexible screen from front to back. Combined with the driving action of the second X-axis drive device 363 and the second Z-axis drive device 362, the flexible screen is accurately placed onto the feeding device 31. The second X-axis drive device 363 and the second Z-axis drive device 362 are both existing linear modules, and their specific structural composition and working principle will not be described in detail here.

[0040] In this embodiment, the base 1 is provided with a second support 12, which is spaced apart from the first support 11. The positioning device 32 and the cutting device 33 are respectively provided on both sides of the second support 12. The positioning device 32 includes a third movable seat 321, a third X-axis driving device 322 for driving the third movable seat 321 to move along the X-axis direction of the second support 12, a CCD camera 323 and a positioning frame 324 provided on the third movable seat 321, and a fill light 325 provided on the positioning frame 324. The third movable seat 321 is provided with a positioning hole 326. The positioning frame 324 is provided with a positioning groove 327 at one end near the CCD camera 323. The positioning groove 327 is connected to the positioning hole 326. Multiple positioning holes 326 are provided, and the multiple positioning holes 326 are arranged in a rectangular array. The cutting device 33 is arranged in a column; it includes a fourth movable seat 331, a third Z-axis drive device 332 for driving the fourth movable seat 331 to move along the Z-axis direction of the second stand 12, a fourth X-axis drive device 333 for driving the third Z-axis drive device 332 to move along the X-axis direction of the second stand 12, a laser cutting head 334 disposed on the fourth movable seat 331, and an exhaust gas processor 335 disposed on the fourth movable seat 331. The exhaust gas processor 335 includes a mounting frame 3351, a collection cavity 3352 disposed on the mounting frame 3351, and an exhaust pipe 3353 disposed outside the collection cavity 3352. The mounting frame 3351 is connected to the fourth movable seat 331. The collection cavity 3352 is provided with a through hole 3354 for the laser emitted by the laser cutting head 334 to pass through.

[0041] Specifically, multiple positioning holes 326 are arranged in a rectangular array on the third movable seat 321. External screws are used to pass through the positioning grooves 327 and then connect to the positioning holes 326, thereby accurately adjusting the distance between the fill light 325 and the CCD camera 323 according to actual working needs. This ensures high work compatibility. The fill light 325 is often used in conjunction with the CCD camera 323. The fill light 325 adopts a ring structure, which provides a wide illumination range, reduces image noise, maintains high color fidelity and detail retention, and achieves better shooting results in dynamic range usage scenarios. This allows the CCD camera 323 to perform high-definition positioning and shooting of the flexible screen shape. Combined with image algorithms, this achieves good positioning accuracy. The positioning device 32 and the cutting device 33 are respectively set on both sides of the second stand 12. The third X-axis drive device 322 drives the CCD camera 323 to move left and right along the X-axis direction of the second stand 12 through the third movable seat 321, which facilitates the positioning of the flexible screen. The third Z-axis drive device 332 drives the laser cutting head 334 and the exhaust gas processor 335 to move up and down along the Z-axis of the second stand 12 via the fourth movable seat 331. The fourth X-axis drive device 333 drives the third Z-axis drive device 332 to move left and right along the X-axis of the second stand 12, expanding the range of movement. The laser cutting head 334 preferably uses an ultraviolet picosecond laser or an ultraviolet femtosecond laser. The exhaust pipe 3353 is connected to an external exhaust fan, and the collection chamber 3352 is connected to the exhaust pipe 3353. When the laser emitted by the laser cutting head 334 passes through the through hole 3354 and then cuts the flexible screen, the exhaust gas generated during the cutting process is uniformly drawn away through the collection chamber 3352, thereby effectively collecting and discharging the exhaust gas. Among them, the third X-axis drive device 322, the fourth X-axis drive device 333, and the third Z-axis drive device 332 are all existing linear modules, and their specific structural composition and working principle will not be described in detail here.

[0042] The feeding device 31 in this embodiment includes a feeding base 311, a feeding linear module 312 drivenly connected to the feeding base 311, a first vacuum suction hole 313 disposed on the feeding base 311, and a waste collection box 314 disposed on the outside of the feeding base 311. The feeding base 311 is provided with a first material sensor 315. Multiple first vacuum suction holes 313 are provided, and multiple first vacuum suction holes 313 are arranged around the circumference of the first material sensor 315. A waste edge collection box 13 is provided on the side of the base 1 near the waste discharge device 34. Specifically, multiple first vacuum suction holes 313 are arranged around the first material sensor 315 in the circumference, and the multiple first vacuum suction holes 313 are connected to an external vacuum pump. When the flexible screen blocks the first material sensor 315, the first material sensor 315 senses and determines the presence of the flexible screen and feeds back to the PLC control system. The PLC control system controls the start of the vacuum pump to operate, and the multiple first vacuum suction holes 313 are used to stably adsorb the flexible screen. The degree of intelligent control is high. When the second lifting cylinder 352 drives the cleaning brush 351 to clean the surface of the flexible screen, the dust can be concentrated and swept into the waste collection box 314. The waste discharge device 34 places the waste edge film into the waste edge collection box 13 for convenient collection and treatment.

[0043] The feeding mechanism 2 in this embodiment includes a feeding device 21, a pre-positioning device 22 spaced apart from the feeding device 21, a first transfer robot 23 movably disposed between the feeding device 21 and the pre-positioning device 22, and a second transfer robot 24 used in conjunction with the pre-positioning device 22. The first transfer robot 23 includes an assembly frame 231, a paper picking and placing device 232 disposed on the assembly frame 231, a picking device 233 movably disposed on the assembly frame 231, a first Y-axis drive device 234 for driving the picking device 233 to move along the Y-axis direction of the assembly frame 231, and a fifth X-axis drive device 235 for driving the first Y-axis drive device 234 to move along the X-axis direction of the base 1. The paper picking and placing device 232 includes a first support 2321, a lifting frame 2322 movably disposed on the first support 2321, a third lifting cylinder 2323 drivenly connected to the lifting frame 2322, and a third vacuum suction head 2324 disposed on the lifting frame 2322. Specifically, during operation, an AGV intelligent handling robot using existing technology moves a rack containing stacked flexible screens to a loading device 21. The loading device 21 picks up the flexible screens from the rack and transports them from bottom to top. A first transfer robot 23 then moves the flexible screens loaded by the loading device 21 to a pre-positioning device 22 for pre-positioning processing, adjusting the position and angle of the flexible screens. Immediately afterwards, a second transfer robot 24 removes the pre-positioned flexible screens. Because the loading device 21 and the pre-positioning device 22 are spaced apart, and the first transfer robot 23 is movably positioned between the two devices, while the second transfer robot 24 reciprocates on the pre-positioning device 22, multiple working components are integrated and assembled on the base 1, resulting in a compact overall layout and small footprint. The feeding device 21, the pre-positioning device 22, the first transfer robot 23, and the second transfer robot 24 are all electrically connected to the PLC control system. The PLC control system intelligently controls the operation of each working component. Since the PLC control system is existing technology, the specific composition and working principle of the PLC control system will not be described in detail here. The paper picking and placing device 232 and the first Y-axis drive device 234 are both set on the assembly frame 231. The first Y-axis drive device 234 drives the picking device 233 to move along the Y-axis direction of the assembly frame 231. The fifth X-axis drive device 235 drives the paper picking and placing device 232 and the picking device 233 to move along the X-axis direction of the base 1 through the assembly frame 231. This causes the third lifting cylinder 2323 to drive the third vacuum suction head 2324 to move up and down through the lifting frame 2322, taking out the paper placed on the flexible screen and then transferring it to the paper recycling part of the feeding device 21, so that the picking device 233 can accurately pick up and place the flexible screen. In addition, the fifth X-axis drive device 235 and the first Y-axis drive device 234 are both existing linear modules, and their specific structural composition and working principle will not be described in detail here.

[0044] The material handling device 233 in this embodiment includes a second support 2331, a fifth movable seat 2332 movably disposed on the second support 2331, a third rotary cylinder 2333 rotatably connected to the fifth movable seat 2332, and a first material handling component 2334 and a second material handling component 2335 disposed on the fifth movable seat 2332. The first material handling component 2334 and the second material handling component 2335 have the same structure. The first material handling component 2334 includes a first lifting seat 23341, a first main suction head 23342 disposed on the first lifting seat 23341, and a fourth lifting cylinder 23343 drivenly connected to the first lifting seat 23341. The first main suction head 23342 is provided in multiple ways, and the multiple first main suction heads 23342 are arranged in a rectangular array. The first lifting seat 23341 is provided with an adjusting plate 23344. The adjusting plate 23344 is provided with an assembly plate 23345. The adjusting plate 23344 and the assembly plate 23345 are arranged perpendicularly. The assembly plate 23345 is provided with a secondary suction head 23346. The adjusting plate 23344 is provided with an adjusting groove 23347. The adjusting groove 23347 is arranged along the length direction of the adjusting plate 23344. The assembly plate 23345 is provided with an assembly hole 23348 that communicates with the adjusting groove 23347.

[0045] Specifically, the first Y-axis drive device 234 drives the picking device 233 to move along the Y-axis direction of the assembly frame 231, realizing the forward and backward movement of the picking device 233 with a wide range of motion. Furthermore, the third rotary cylinder 2333 drives the first picking component 2334 and the second picking component 2335 to rotate circumferentially via the fifth movable seat 2332. Since the first picking component 2334 and the second picking component 2335 have the same structure, the fourth lifting cylinder 23343 drives the first main suction head 23342 to move up and down via the first lifting seat 23341, thereby using the first main suction head 23342 to stably adsorb the surface of the flexible screen, and then rotates it to the pre-positioning device 22 via the third rotary cylinder 2333. Preferably, the adjusting plate 23344 and the assembly frame 231... Two mounting plates 23345 are provided, with two adjusting plates 23344 spaced apart horizontally and two assembly plates 23345 spaced apart front and back. The adjusting groove 23347 is set along the length of the adjusting plate 23344. The adjusting plate 23344 moves and adjusts its position along the length of the assembly plate 23345. Then, external screws are used to pass through the adjusting groove 23347 and are then connected and fixed in the assembly hole 23348, thereby fixing the position of the assembly plate 23345 on the adjusting plate 23344. This further increases the adsorption area, which is beneficial for the auxiliary suction head 23346 and the main suction head to work together to adsorb large-sized flexible screens, improve adsorption stability, enhance work compatibility, and avoid accidental bending of large-sized flexible screens during loading and unloading.

[0046] The feeding device 21 in this embodiment includes a first loading rack 211, a first loading arm 212 disposed on the first loading rack 211, a fourth Z-axis drive device 213 for driving the first loading rack 211 to move along the Z-axis direction of the base 1, a second loading rack 214 used in conjunction with the first loading rack 211, a second loading arm 215 disposed on the second loading rack 214, and a second Y-axis drive device 216 for driving the second loading rack 214 to move along the Y-axis direction of the base 1. The first loading arm 212 is provided with... The second material sensor 217, the first material carrying arm 212 is provided in multiple ways, the multiple first material carrying arms 212 are arranged at intervals along the length direction of the first material carrying frame 211, the second material carrying arm 215 is provided in multiple ways, the multiple second material carrying arms 215 are arranged at intervals along the length direction of the second material carrying frame 214, the multiple first material carrying arms 212 and the multiple second material carrying arms 215 are arranged alternately, the fourth Z-axis drive device 213 is provided with a connecting frame 218 on the outside, and a position sensor 219 is provided on the top of the connecting frame 218. Specifically, the existing AGV intelligent handling robot moves the stacked flexible screen rack to the side of the second loading rack 214. The second loading arm 215, which is set on the second loading rack 214, clamps and fixes the flexible screen to the outer wall. The second Y-axis drive device 216 drives the second loading rack 214 to move along the Y-axis direction of the base 1. When the second loading rack 214 moves to the position above the first loading rack 211, the second material sensor 217, which is set on the first loading arm 212, senses and detects the presence of the flexible screen. This causes the fourth Z-axis drive device 213 to drive the first loading rack 211 to move upward, so that the first loading arm 212 clamps and fixes the flexible screen to the outer wall. This causes the flexible screen to gradually move away from the second loading rack 214 until it is lifted to the position below the first transfer robot 23, so that the first transfer robot 23 can accurately pick up the flexible screen.Furthermore, the second Y-axis drive device 216 and the fourth Z-axis drive device 213 are both existing linear modules, and their specific structural composition and working principle will not be elaborated here. Preferably, three first loading arms 212 are provided, spaced apart along the length of the first loading frame 211. Three second loading arms 215 are provided, spaced apart along the length of the second loading frame 214. Because the three first loading arms 212 and three second loading arms 215 are staggered, the three first loading arms 212 can smoothly pass through the three second loading arms 215, allowing the first loading arms 212 to smoothly pick up the flexible screen from the second loading arms 215. The vertical movement ensures that the forward and backward movement of the second loading arm 215 does not interfere with the vertical movement of the first loading arm 212, resulting in high coordination. The connecting frame 218 is located beside the fourth Z-axis drive device 213, and the position sensor 219 is located on top of the connecting frame 218. Since the position sensor 219 is electrically connected to the PLC control system, and the PLC control system is electrically connected to the fourth Z-axis drive device 213, the PLC control system receives the position information of the flexible screen from the position sensor 219 and controls the fourth Z-axis drive device 213 to pause operation, thereby raising the flexible screen to a preset height position, resulting in high operational safety.

[0047] The pre-positioning device 22 in this embodiment includes a third support 221, a second movable base 222 disposed on the third support 221, a camera 223 disposed on the second movable base 222, a sixth X-axis drive device 224 for driving the second movable base 222 to move along the X-axis direction of the third support 221, a material platform 225 disposed on the third support 221, and a third Y-axis drive device 226 for driving the material platform 225 to move along the Y-axis direction of the third support 221. The material platform 225 is provided with a third material sensor 227 and a second vacuum suction hole 228. Multiple second vacuum suction holes 228 are provided, and the multiple second vacuum suction holes 228 are arranged around the circumference of the third material sensor 227. The second material transfer robot 24 includes a fourth bracket for driving the fourth bracket along the Y-axis of the base 1. The system includes a fourth Y-axis drive device 242 for directional movement, a seventh X-axis drive device 243 for driving the fourth Y-axis drive device 242 to move along the X-axis direction of the base 1, a sixth movable seat 244 movably mounted on the fourth bracket, a linear rotary actuator 245 drivenly connected to the sixth movable seat 244, and a third material picking assembly 246 and a fourth material picking assembly 247 mounted on the sixth movable seat 244. The third material picking assembly 246 and the fourth material picking assembly 247 have the same structure. The third material picking assembly 246 includes a second lifting seat 2461, a fourth vacuum suction head 2462 mounted on the second lifting seat 2461, and a fifth lifting cylinder 2463 drivenly connected to the second lifting seat 2461. Multiple fourth vacuum suction heads 2462 are provided and arranged in a rectangular array.

[0048] Specifically, preferably, two cameras 223 are provided, spaced apart on the second movable base 222. The sixth X-axis drive device 224 drives the second movable base 222 to move along the X-axis direction of the third stand 221. Preferably, two loading platforms 225 are provided. The first material picking component 2334 and the second material picking component 2335 respectively place the two flexible screens on the two loading platforms 225. The two loading platforms 225 are spaced apart at the output end of the third Y-axis drive device 226. The third Y-axis drive device 226 drives the two loading platforms 225 to move along the Y-axis direction of the third stand 221, thereby moving the two flexible screens below the two cameras 223. This allows the two cameras 223 to capture a comprehensive view of the overall outline of the two flexible screens and collect corresponding position information. In conjunction with the third rotary cylinder 2333, the first material picking component 2334 and the second material picking component 2335 are driven to rotate at multiple angles, thereby miniaturizing and correcting the position of the flexible screen on the loading platform 225, achieving good position adjustment. In addition, the sixth X-axis drive device 224 and the third Y-axis drive device 226 are both existing linear modules, and their specific structural composition and working principle will not be described in detail here.

[0049] Because the linear rotary actuator 245 drives the third and fourth material-picking components 246 and 247 to move up and down and rotate in a circular motion via the sixth movable seat 244, and because the linear rotary actuator 245 is mounted on the fourth bracket, the fourth Y-axis drive device 242 drives the fourth bracket to move along the Y-axis direction of the base 1, and the seventh X-axis drive device 243 drives the fourth Y-axis drive device 242 to move along the X-axis direction of the base 1, thereby driving the third and fourth material-picking components 246 and 247 to move forward and backward and left and right, the actuator has a wide range of motion, which facilitates the removal of the flexible screen from the pre-positioning device 22 and its transfer to the subsequent processing mechanism. Furthermore, the seventh X-axis drive device 243 and the fourth Y-axis drive device 242 are both existing linear modules, and their specific structural composition and working principle will not be described in detail here. The linear rotary actuator 245 is an existing technology. Through internal structural design, it integrates linear drive units such as voice coil motors and lead screws with rotary drive units such as servo motors. This is a highly integrated drive device that can simultaneously complete linear and rotary compound motion. It integrates Z-axis linear motion and R-axis rotary motion in a compact space and is widely used in high-precision automation fields such as semiconductors and 3C electronics. Therefore, its specific structural composition and working principle will not be described in detail here.

The unloading robot 41 includes a rotating frame 411, a fourth rotary cylinder 412 rotatably connected to the rotating frame 411, and a fifth vacuum suction head 413 disposed on the rotating frame 411. Specifically, the fifth Y-axis drive device 42 drives the unloading robot 41 to move back and forth along the Y-axis direction of the base 1, and the eighth X-axis drive device 43 drives the fifth Y-axis drive device 42 to move left and right along the X-axis direction of the base 1, thereby driving the fifth vacuum suction head 413 to move left and right and back and forth. This allows the fourth rotary cylinder 412 to drive the fifth vacuum suction head 413 to rotate clockwise or counterclockwise through the rotating frame 411, effectively removing the flexible screen smoothly and achieving high unloading efficiency.
