Description

Technical Field

[0001] This invention relates to the field of LED flexible display processing equipment technology, and in particular to a multi-station laser cutting equipment for LED flexible displays. Background Technology

[0002] Flexible LED displays, with their advantages of being ultra-thin, flexible, high-contrast, and low-power, are rapidly penetrating fields such as smartphones, wearable devices, automotive displays, and advertising media, resulting in explosive growth in market demand. The core substrate of flexible screens is a multi-layered composite structure consisting of PI film, PET film, and flexible glass, and integrates precision circuits and light-emitting units. This places stringent requirements on the cutting process, including micron-level precision, stress-free operation, low thermal damage, and high yield.

[0003] In existing technologies, a torsion spring and abutment plate are used to form an elastic abutment structure. The flexible LED film material is relatively fragile. Using rigid clamping not only leads to unstable clamping and poor positioning repeatability, but also allows the laser cutting device for flexible LED displays to perform unidirectional cutting, resulting in a slow cutting rate and affecting the production efficiency of the display. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: using rigid clamping not only leads to unstable clamping and poor positioning repeatability, but also limits the laser cutting device for LED flexible displays to unidirectional cutting, resulting in a slow cutting rate and thus affecting the production efficiency of the display.

[0008] Mounting plates, two mounting plates are disposed on both sides of the square box, and the mounting plates are respectively hinged to two sliders through hinge plates, and each mounting plate has two through slots;

[0009] A limiting assembly is installed between the mounting plate and the square box. The limiting assembly includes a placement plate, a sealing plate, and inflatable bags. The placement plate is installed at one end of the through groove and is provided with multiple suction cups. The sealing plate is installed at the other end of the through groove. Two inflatable bags are respectively installed in the cavity of the square box, and gaskets are fixedly connected to both ends of each bag. The gaskets are fixedly connected to the slider by a third spring. The inflatable bags are connected to the two through grooves by two connecting pipes.

[0010] Preferably, two cylinders are fixedly connected to one end of the square box, and a slidably connected disc is installed inside the cylinder. The disc has a circular hole. A pull rod is slidably connected to the side wall of the cylinder near the square box. One end of the pull rod is fixedly connected to the disc, and the other end of the pull rod is fixedly connected to one of the sliders in the cavity.

[0011] Preferably, each mounting plate has two support boxes fixedly connected to the end away from the square box. One of the support boxes on the same mounting plate has a storage cavity. A cover plate for sealing is installed at one end of the storage cavity. A piston plate is slidably connected inside the storage cavity. The two storage cavities are respectively connected to the cylinder through connecting pipes. The storage cavities are filled with hydraulic oil.

[0012] Preferably, each of the mounting plates is slidably connected to a pressing plate, the pressing plate being L-shaped, with one end slidably connected to the piston plate, and the other end of the pressing plate being fixedly connected to the upper surface of the mounting plate with a first spring.

[0013] Preferably, a rotating shaft is rotatably connected to another support box, and gears are fixedly connected to both ends of the rotating shaft. The two gears are respectively arranged on both sides of the support box, and a baffle is slidably connected to the mounting plate, with one side of the baffle meshing with the gear.

[0014] Preferably, a protrusion is fixedly connected to one side of the mounting plate, an elliptical plate is slidably connected to the protrusion, a rack plate is fixedly connected to the lower end of the elliptical plate, the rack plate meshes with the gear, a fourth spring is fixedly connected between the upper surface of the rack plate and the lower surface of the protrusion, and a ball is rotatably connected to the lower end of the rack plate.

[0015] Preferably, a support plate is slidably connected to the upper end of the base plate, and a second spring is fixedly connected to the upper surface of the base plate at each of the four corners of the support plate. The support plate is slidably connected to the support rod.

[0016] Preferably, a clamping plate is fixedly connected to the upper surface of one end of the base plate, and the clamping plate is slidably connected to the support plate.

[0017] Preferably, the base has an installation groove, a foot pedal is slidably connected in the installation groove, one end of the foot pedal is fixedly connected to a column, and the end of the column away from the foot pedal passes through the base plate and is fixedly connected to the support plate.

[0018] Preferably, two laser cutting heads are installed on the base, the laser cutting heads are located on the upper side of the placement plate, a U-shaped rod is installed between the square box and the mounting plate, and a limit plate is fixedly connected to the mounting plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By symmetrically setting mounting plates on both sides of the square box, two sets of laser cutters can be used for synchronous cutting during the processing. At the same time, the loading and unloading of another set of materials can be completed during the cutting process, which reduces the equipment standby time, makes full use of the working time of the laser cutting head, and improves the processing capacity per unit time.

[0021] 2. The LED flexible display screen is fixed by negative pressure adsorption. Multiple suction cups are used to evenly adsorb the material surface, avoiding problems such as material deformation and edge damage caused by traditional rigid clamping. Combined with the lateral limiting effect of the limiting plate, the stability of the fixation is guaranteed, while also improving the accuracy of material placement and positioning, and ensuring cutting precision.

[0022] 3. By cooperating with the cylinder, hydraulic oil, and disc, the ejection process of the mounting plate is buffered, allowing the mounting plate to move out at a uniform speed. This avoids the vibration waves generated by the rapid ejection of the mounting plate and the processing station on the opposite side, ensuring the stability of the cutting process and reducing the probability of defective products.

[0023] 4. When changing workstations, the pallet moves downward, driving the rack to move. Through gear meshing, the baffle automatically descends, preventing the baffle from colliding with the laser cutting head. After the workstation rotation is completed and the pallet resets, the baffle automatically rises, separating the cutting areas of the two workstations. This effectively blocks airflow disturbances and heat transfer generated during cutting, preventing any impact on the processing accuracy of the other cutting workstation. The overall structure has strong linkage and a high degree of automation, eliminating the need for additional manual operation of the baffle lifting and lowering, thus simplifying the material changing process for workers.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figure 1 , Figure 4 , Figure 8A multi-station laser cutting equipment for flexible LED displays, comprising:

[0037] The base 1 and the base plate 3 are disposed within the base 1. A support plate 4 is slidably connected to the upper end of the base plate 3. Second springs 23 are fixedly connected to the four corners of the support plate 4 and the upper surface of the base plate 3. The support plate 4 is slidably connected to the support rod 26. The second springs 23 exert an upward pushing force on the support plate 4, which in turn exerts an upward compressive force on the support box 8, thereby achieving the fixing effect of the mounting plate 5. The fixing of the mounting plate 5 is based on the elastic potential energy of the second spring 23. The greater the elastic potential energy of the second spring 23, the greater the compressive force on the support box 8 and the mounting plate 5, and the better the mounting effect. The higher the stability of plate 5, the more stable the base plate 3 becomes. A clamping plate 22 is fixedly connected to the upper surface of one end of the base plate 3. The clamping plate 22 is slidably connected to the support plate 4. When the mounting plate 5 moves away from the square box 6, the clamping plate 22 is positioned between the two support boxes 8, which can limit the position of the support boxes 8 and further limit the position of the mounting plate 5, preventing it from continuing to rotate. This further increases the stability of the two mounting plates 5 and prevents them from shifting due to external forces or mechanical vibrations during material cutting and changing. A groove is provided on the base 1. The base plate 3, support plate 4, and mounting plate 5 are installed, and the support plate 4 is limited to slide vertically. The base plate 3 is convex and fixedly connected to the bottom wall of the groove. A vertically arranged support rod 26 is fixedly connected to the upper surface of the base plate 3. The support rod 26 supports the square box 6, ensuring that the square box 6 is always on the same horizontal line. The support rod 26 and the square box 6 are detachable for replacing the square box 6 and the mounting plate 5. Different sized placement plates 12 on the mounting plate 5 can be used to... It is suitable for cutting and processing flexible LED displays of different sizes, and also facilitates the maintenance of the square box 6 and the mounting plate 5. The square box 6 can rotate on the support rod 26. The end of the support rod 26 away from the base plate 3 is rotatably connected to the square box 6. Therefore, both mounting plates 5 are installed on the square box 6 and are set in a mirror image with the square box 6 as the axis of symmetry. The square box 6 consists of two chambers, and two sliders 24 are slidably connected in each chamber. The two chambers are not connected. The structure in each chamber controls the movement of the mounting plate 5 on one side.

[0038] Reference Figure 4 , Figure 5 , Figure 8The base 1 has an installation groove, in which a foot pedal 2 is slidably connected. One end of the foot pedal 2 is fixedly connected to a column 20. The end of the column 20 away from the foot pedal 2 passes through the base plate 3 and is fixedly connected to the support plate 4. The column 20 supports the foot pedal 2. The foot pedal 2 moves vertically in the installation groove and pulls the support plate 4 downward through the column 20. When the support plate 4 moves downward and away from the support box 8, it no longer exerts pressure on the support box 8, and can easily push the mounting plate 5 and the square box 6 to rotate on the support rod 26. During the rotation, the ball 31 rolls on the surface of the support plate 4 to reduce the friction between it and the support plate 4. Two laser cutting heads 7 are installed on the base 1. The operation of the laser cutting heads 7 is controlled by a motion system. The motion system usually adopts a motor drive and transmission components to realize the movement of the cutting head in the plane coordinate system. The CNC system receives instructions from the control software and coordinates the movement of each axis to make the cutting head run according to the predetermined trajectory. The laser cutting heads 7 are set on the upper side of the placement plate 12. When the laser cutting heads 7 work synchronously, It can simultaneously cut two flexible LED displays on the mounting plate 5. Both the square box 6 and the mounting plate 5 have insertion holes on their side walls. One end of the U-shaped rod 38 is inserted into the insertion hole on the square box 6, and the other end is inserted into the insertion hole on the mounting plate 5, thereby achieving the effect of snapping the square box 6 and the mounting plate 5 together using the U-shaped rod 38. The U-shaped rod 38 is installed between the square box 6 and the mounting plate 5, and both ends of the U-shaped rod 38 are inserted into the insertion holes of the mounting plate 5 and the square box 6, respectively. At the same time, there is a large friction between the outer surface of the U-shaped rod 38 and the inner wall of the insertion hole, so it will not be dislodged by mechanical vibration during operation. A limiting plate 15 is fixedly connected to the mounting plate 5. The limiting plate 15 is composed of multiple non-connected limiting blocks. Multiple limiting blocks surround the placement plate 12. When the flexible LED display is placed on the upper surface of the placement plate 12, it is between multiple limiting blocks. The multiple limiting blocks will play a lateral limiting role for the flexible LED display, and also facilitate the quick and accurate placement of the flexible LED display on the placement plate 12.

[0039] Reference Figures 1-3 , Figure 5 , Figure 7Mounting plates 5 are arranged on both sides of the square box 6, and the mounting plates 5 are hinged to two sliders 24 respectively via hinge plates 14. When the mounting plates 5 are in contact with the square box 6, the hinge plates 14 and the air bags 16 are arranged in a parallel state and are both located in the cavity of the square box 6 without interfering with each other. The two sliders 24 move away from or towards each other in the cavity. The two sliders 24 and the hinge plates 14 can provide stable support for the mounting plates 5, allowing the mounting plates 5 to move horizontally. Each mounting plate 5 has two through slots. A limiting component is installed between the mounting plate 5 and the square box 6. The limiting component includes a placement plate 12, a sealing plate 35, and an air bag 16. The placement plate 12 is installed in the through slot. One end of the placement plate 12 is equipped with multiple suction cups, the upper surfaces of which are flush with the upper surface of the placement plate 12. Due to the large number and high density of suction cups, the LED flexible display screen will not be deformed when it is adsorbed, so that the LED flexible display screen remains horizontal under the support of the placement plate 12. At the same time, when the two sliders 24 move away from each other, the third spring 25 exerts a pulling force on the air bag 16. When the suction cups adsorb the LED flexible display screen and the channel is under moving negative pressure, the gas in the channel no longer flows into the air bag 16, and the third spring 25 will be stretched. At this time, the third spring 25 acts as a buffer for the air bag 16, preventing damage caused by external hard stretching of the air bag 16. Meanwhile, if the suction cups do not adhere to the flexible LED display, it indicates that the display is not properly positioned. Workers can manually adjust the display's position to ensure it is level, preventing issues with subsequent cutting. Similarly, the placement plate 12 moves horizontally back and forth. When the suction cups adhere to the display, it indicates the display is level and ready for cutting. The sealing plate 35 is installed at the other end of the slot. When the flexible LED display is placed on the placement plate 12, it seals the multiple suction cups, preventing leakage into the slot. Two inflatable bags 16 are installed in the chambers of the square box 6, and each end is fixedly connected to a gasket 27. Each chamber has one inflatable bag 16 and two sliders 24. The gasket 27 is fixedly connected to the slider 24 through a third spring 25. The gasket 27 is a metal sheet. The third spring 25 pulls the inflatable bag 16 through the gasket 27 to avoid damage to the inflatable bag 16. At the same time, the inflatable bag 16 has high temperature resistance and elasticity. Meanwhile, the surface of the square box 6 is coated with a heat insulation coating to prevent the temperature generated by laser cutting from affecting the normal operation and service life of the inflatable bag 16. When the inflatable bag 16 is stretched, it can automatically return to its original state after the external tension is removed. The inflatable bag 16 is connected to two through slots through two connecting pipes 17.

[0040] Reference Figures 9-10Two cylinders 10 are fixedly connected to one end of a square box 6. A slidably connected disc 37 is installed inside the cylinder 10. The disc 37 has a circular hole. A pull rod 36 is slidably connected to the side wall of the cylinder 10 near the square box 6. A sealing structure is provided at the slidable connection between the pull rod 36 and one side wall of the cylinder 10 to prevent the hydraulic oil inside the cylinder 10 from flowing out. One end of the pull rod 36 is fixedly connected to the disc 37, and the other end of the pull rod 36 is fixedly connected to one of the sliders 24 in the cavity. The two cylinders 10 correspond to the structures in the two cavities respectively and do not interfere with each other.

[0041] Reference Figure 2 , Figure 7 Each mounting plate 5 has two support boxes 8 fixedly connected to the end furthest from the square box 6. One of the support boxes 8 on the same mounting plate 5 has a storage cavity. A cover plate 33 is installed at one end of the storage cavity for sealing. The cover plate 33 is used to seal the storage cavity. At the same time, opening the cover plate 33 can fill the storage cavity with hydraulic oil. A piston plate 34 is slidably connected inside the storage cavity. The two storage cavities are respectively connected to the cylinder 10 through the connecting pipe 32. The storage cavities are filled with hydraulic oil, which is located below the piston plate 34. When the piston plate 34 is pushed, it can squeeze the hydraulic oil through the connecting pipe 32 into the cylinder 10. Each mounting plate 5 has a pressing plate 9 slidably connected to it. The pressing plate 9 is L-shaped, and one end is connected to... The piston plate 34 is slidably connected, and the outer surface of the pressing plate 9 is covered with a sealing gasket. The sealing gasket is slidably connected to the side wall of the support box 8 to prevent oil leakage from the storage cavity. The other end of the pressing plate 9 is fixedly connected to the upper surface of the mounting plate 5 with a first spring 13. When the pressing plate 9 is released, the pressing plate 9 moves upward and resets under the elastic force of the first spring 13. At this time, the hydraulic oil in the cylinder 10 will return to the storage cavity. When it is necessary to push the mounting plate 5 to fit with the square box 6, it is not necessary to press the pressing plate 9. At this time, the hydraulic oil in the cylinder 10 is not full. Therefore, when pushing the mounting plate 5, the movement of the slider 24 will not be buffered by the hydraulic oil, and the mounting plate 5 can be quickly pushed to fit with the square box 6.

[0042] Reference Figures 6-7A rotating shaft 19 is rotatably connected to another support box 8. Gears 18 are fixedly connected to both ends of the rotating shaft 19. The two gears 18 are respectively located on both sides of the support box 8. One of the gears 18 on the same rotating shaft 19 meshes with a rack plate 21, and the other gear 18 is located between the two support boxes 8 and meshes with one side of a baffle 11. A baffle 11 is slidably connected to the mounting plate 5. One side of the baffle 11 meshes with a gear 18. A protrusion 29 is fixedly connected to one side of the mounting plate 5. An elliptical plate 30 is slidably connected to the protrusion 29. The elliptical plate 30 slides vertically on the protrusion 29 and does not rotate. A rack plate 21 is fixedly connected to the lower end of the elliptical plate 30. The rack plate 21 meshes with the gear 18. A fourth spring 28 is fixedly connected between the upper surface of the rack plate 21 and the lower surface of the protrusion 29. A ball is rotatably connected to the lower end of the rack plate 21. 31. The fourth spring 28 always exerts a downward pushing force on the rack plate 21, so that the ball 31 always presses against the upper surface of the support plate 4 and moves up and down with the support plate 4. The ball 31 is installed at the lower end of the rack plate 21 in the same way as the ballpoint pen ball, so that the ball 31 can roll at the lower end of the rack plate 21, thereby reducing the friction with the support plate 4 and allowing the mounting plate 5 to rotate easily. Therefore, the up and down movement of the support plate 4 is used to drive the movement of the rack plate 21, thereby controlling the movement of the baffle 11. After the baffle 11 moves down, it can be lower than the laser cutting head 7. When the baffle 11 is reset and moved up, it is between the two laser cutting heads 7. The baffle 11 can further block the airflow disturbance and residual heat turbulence generated during the cutting of the two LED flexible displays, and will not interfere with the running posture and focusing accuracy of the laser cutting heads 7 in adjacent workstations.

[0043] In this invention, as shown in the appendix Figure 1 As shown, when the operator stands on the side of the base 1 with the foot pedal 2, the two laser cutting heads 7 are driven to simultaneously cut the LED flexible display screen located on the lower placement plate 12. During the cutting of the LED flexible display screen on one of the mounting plates 5, the operator uses their fingers to press the pressing plate 9 on the other mounting plate 5 downwards and compress the first spring 13. As the pressing plate 9 moves downwards, it pushes the piston plate 34 to slide in the storage cavity and squeezes the hydraulic oil through the connecting pipe 32 into the corresponding cylinder 10 close to the operator. At this time, the U-shaped rod 38 between the square box 6 and the mounting plate 5 close to the operator is pulled out. The U-shaped rod 38 no longer limits the mounting plate 5. The air bag 16 and the third spring 25 in the cavity close to the operator retract to their original state. At the same time, it pulls the two sliders 24 to move centrally in the cavity. When the two sliders 24 move centrally, they can push the mounting plate 5 to move away from the square box 6 through the hinge plate 14 to the position shown in the attached figure. Figure 2As shown, during the movement of the two sliders 24 in the center, one of the sliders 24 pulls the disc 37 to slide inside the cylinder 10 via the pull rod 36. At this time, the hydraulic oil inside the cylinder 10 can buffer the movement of the disc 37, allowing the hydraulic oil on one side of the disc 37 to flow to the other side through the circular hole. The flow rate of the circular hole is limited, so that the disc 37 moves at a constant speed inside the cylinder 10. Since the slider 24 is fixed to the disc 37 via the pull rod 36, the slider 24 moves at a constant speed under the tension of the third spring 25 and the air bag 16. The mounting plate 5 is hinged to the slider 24 via the hinge plate 14. Therefore, when the mounting plate 5 moves away from the square box 6, it also slides at a constant speed, avoiding excessive movement speed of the mounting plate 5 from causing vibration damage to the processed LED flexible display screen.

[0044] When the slider 24 moves in the center, the third spring 25 and the air bag 16 contract and return to their original state. The gas inside the air bag 16 is delivered to the two through slots through the two connecting pipes 17 respectively. The other end of the through slot is sealed by the sealing plate 35. After the airflow enters the through slot, the inside of the through slot is no longer under negative pressure. Since the suction cups are connected to the through slots, the multiple suction cups on the placement plate 12 no longer have an adsorption force on the surface of the LED flexible display screen. The operator can then quickly remove the two LED flexible displays from the installation plate 5 and put them back into the LED flexible display screen to be processed. The LED flexible display screen is placed on the upper surface of the placement plate 12 and is limited by the limiting plate 15 to prevent the LED flexible display screen from shifting laterally on the placement plate 12, so that the LED flexible display screen can be centered and attached to the upper surface of the placement plate 12.

[0045] Then, push the mounting plate 5 back to its original state and fit it against the square box 6. Then, use the U-shaped rod 38 to fix the mounting plate 5 back onto the square box 6. As the mounting plate 5 moves closer to the square box 6, the hinge plate 14 will push the two sliders 24 away from each other, so that the two sliders 24 pull the two ends of the air bag 16 respectively through the third spring 25. After the air bag 16 is stretched, the gas in the through groove enters the air bag 16 through the connecting pipe 17. At this time, a negative pressure environment is formed in the through groove. Under the action of negative pressure, the multiple suction cups on the placement plate 12 firmly adhere to the LED flexible display screen, realizing flexible and damage-free fixed positioning, avoiding hard clamping and damaging the material while ensuring positioning accuracy.

[0046] At this time, the worker uses their foot to press down on pedal 2, which pulls the support plate 4 down through the column 20 and compresses the second spring 23. As the support plate 4 moves down, it no longer exerts vertical pressure on the support box 8. At the same time, the rack plate 21 moves down with the support plate 4 under the elastic force of the fourth spring 28. Since the rack plate 21 and the gear 18 are meshed, when the rack plates 21 on the two mounting plates 5 move down synchronously, they can drive the gear 18 and the rotating shaft 19 to rotate respectively. Because one of the gears 18, located on the same rotating shaft 19 and away from the rack plate 21, is meshed with the baffle 11, the baffle 11 can be moved downward through the gear 18 when the rotating shaft 19 rotates. At this time, the height of the two baffles 11 is lower than that of the laser cutting plate. When the cutting head 7 reaches its lowest point, it can push the two mounting plates 5 and the square box 6 to rotate 180 degrees around the support rod 26. The baffle 11 will also rotate without touching the laser cutting head 7. At this time, the two LED flexible displays to be processed are under the laser cutting head 7, and the two LED flexible displays after processing are in front of the operator. Then, the foot pedal 2 is released, and the support plate 4 moves up and resets under the elastic force of the second spring 23, and presses against the support box 8, exerting a vertical upward compressive force on the support box 8 and the mounting plates 5, thereby fixing the two mounting plates 5 and the square box 6 so that the laser cutting head 7 can cut and process the LED flexible displays.

[0047] At the same time, the upward movement of the support plate 4 will drive the rack plate 21 to move upward synchronously. The rack plate 21 drives the gear 18 and the rotating shaft 19 to rotate in the opposite direction, and then drives the baffle 11 to move upward to reset through the gear. At this time, one of the baffles 11 is between the two laser cutting heads 7. The airflow disturbance and residual heat turbulence generated by cutting are further blocked by the baffle 11, so as not to interfere with the running posture and focusing accuracy of the laser cutting heads 7 in adjacent workstations.

[0048] After rotating the two mounting plates 5 and the square box 6 180 degrees around the support rod 26, repeating the above operation allows one station to perform cutting while the other station completes loading and unloading, eliminating the need to stop the machine and waiting. This effectively improves the overall production efficiency of the cutting process. By using multiple stations to rotate alternately, the time spent waiting for the laser cutting head to load and unload is eliminated. At the same time, the expansion and contraction of the air bag, combined with the negative pressure formed by the through groove, achieves flexible adsorption and fixation, which will not damage the flexible display material. It can also automatically judge whether the placement position is level and accurate by the adsorption state, reducing the probability of unqualified cutting. The baffle blocks the airflow and residual heat of adjacent stations during the cutting process, ensuring cutting accuracy. The overall structure is well-coordinated, the loading and unloading operation is simple, safe and stable, and suitable for batch cutting and processing of LED flexible displays.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
