Description

Technical Field

[0001] The present application relates to the technical field of OLED production, and in particular to a raised vacuum adsorption platform. Background Art

[0002] During the assembly process, OLED panels are usually vacuum adsorbed on the platform through a vacuum adsorption platform. However, during the adsorption process, small particles such as dust and assembly debris carried by the OLED panel will also remain on the vacuum adsorption platform. As time goes by, these small particles will accumulate more and more. When a new OLED panel is adsorbed and positioned on the platform, the small particles remaining on the platform will be squeezed with the display module, which can easily produce black spots.

[0003] Chinese patent CN220128564U discloses a vacuum adsorption platform, including a substrate, a plurality of adsorption protrusions and an air source component, wherein the substrate has an adsorption surface, a plurality of adsorption protrusions are arranged at intervals on the adsorption surface, an adsorption channel is formed in each of the adsorption protrusions, the adsorption channel runs through the end of the adsorption protrusion to form an adsorption port, and the air source component includes an air pump, which is connected to the adsorption channel so that the adsorption port generates negative pressure to adsorb the product. In the technical solution of the utility model, a plurality of adsorption protrusions are arranged on the adsorption surface of the substrate, an adsorption channel is formed in the adsorption protrusion, the adsorption channel extends to the upper end of the adsorption protrusion to form an adsorption port, and the adsorption channel is connected to the air pump, which can form a negative pressure at the adsorption port through the adsorption channel to adsorb the product on each adsorption protrusion. In actual use, each adsorption protrusion can effectively reduce the contact area between the display module and the substrate, thereby reducing the possibility of debris remaining on the substrate damaging the product.

[0004] In the prior art, a protruding adsorption portion is used to adsorb the OLED panel, thereby avoiding the situation where the debris remaining on the substrate damages the substrate and produces black spots. However, when it comes to curved screens such as OLED curved screens, simply adsorbing with a protruding suction nozzle cannot fix the curved screen, and the flexible suction nozzle cannot locate the curvature of the curved screen. Compared with the traditional curved adsorption platform that is adapted to the curved structure of the curved screen, it is difficult to achieve adsorption and positioning of the curved screen. Summary of the invention

[0005] In order to overcome the problems existing in the prior art, the present application provides a raised vacuum adsorption platform.

[0006] The present application provides a convex vacuum adsorption platform adopts the following technical solution:

[0007] A raised vacuum adsorption platform comprises a platform body, the platform body comprises a plurality of blocks, the bottom of the blocks are rotatably connected to a base through a lifting mechanism, and the two ends of the base are movably connected to the blocks at the end through side plates, wherein the blocks are connected through a linkage mechanism, the linkage mechanism can drive the blocks to form different angles, an adsorption mechanism is arrayed on the blocks, and the adsorption mechanism is externally connected to a vacuum pump through a pipeline; the linkage mechanism comprises a plurality of groups of rotating shafts and sleeves connected between adjacent blocks, wherein the sleeves are fixedly installed at the top corners of the blocks, arc grooves adapted to the sleeves are opened on adjacent blocks, and the sleeves on a single block are located on a single pair of opposite sides of the block section. The end of the angle line; a protruding locking block is provided on the side of the rotating shaft, and the end of the locking block away from the sleeve is connected to the adjacent block through a telescopic mechanism, and the two ends of the telescopic mechanism are respectively rotatably connected to the locking block and the block, and a placement groove for accommodating the locking block and the telescopic mechanism is opened on the block; an adsorption mechanism, the adsorption mechanism includes an adsorption body and an elastic suction nozzle installed at the output end of the adsorption body, the back of the adsorption body is connected to the vacuum pump through an adsorption pipe, wherein the adsorption body adopts a multi-section pipeline structure, including a fixed section slidably connected to the block, and a rotating section is installed at the output end of the fixed section, wherein the rotating section is connected to the fixed section through a telescopic tube body, and the free end of the rotating section is detachably installed with an elastic suction nozzle.

[0008] By adopting the above technical solution, when the shape of the platform body needs to be adjusted to adapt to the adsorption objects of different shapes during operation, the lifting mechanism can be controlled to make the block perform lifting and lowering actions around the rotating connection point with the base. Since the blocks are connected by the linkage mechanism, the linkage mechanism plays a role in the lifting process. Taking one group of adjacent blocks as an example, when the position of one block changes relative to another block, the shaft rotates in the shaft sleeve, and at the same time, the locking block moves with the rotation of the shaft, and the telescopic mechanism is correspondingly extended and retracted according to the change of the angle between the blocks, thereby ensuring that the linkage mechanism stably drives the blocks to form different angles, and realizes the flexible adjustment of the overall shape of the platform body. In the adsorption working stage, the vacuum pump is started, and the adsorption mechanism is sucked through the adsorption pipe. The fixed section of the adsorption body is connected with the block in a sliding manner, so that the adsorption body can adjust its position in the block according to actual needs, and the suction nozzle can adjust the height of the protruding block surface according to needs. When the OLED panel is placed on the platform, the elastic suction nozzle first contacts the surface of the adsorption object. Since the elastic suction nozzle is elastic, it can fit the surface of the OLED panel well to ensure the sealing adsorption effect. The rotating section is connected to the fixed section through a telescopic tube and can rotate flexibly to further adapt to the curved OLED panel structure, so that the elastic suction nozzle can be more accurately adsorbed to the target position. The platform body is composed of several blocks and connected by a linkage mechanism. It can flexibly adjust the surface shape of the platform according to the different curved structures of the OLED panel, greatly expanding the scope of application of the platform. The adsorption mechanism adopts a multi-section pipeline structure, combined with the design of the elastic suction nozzle and the rotating section and telescopic tube, which enhances the adsorption capacity of the adsorption mechanism for adsorption objects of different shapes and surface conditions, and improves the stability and reliability of adsorption. In addition, the bottom of the block is rotatably connected to the base through a lifting mechanism, which not only helps to adjust the overall shape of the platform, but also can achieve fine-tuning of the height of the adsorption object to a certain extent, further improving the functionality and practicality of the platform.

[0009] Preferably, the lifting mechanism includes a lifting cylinder connecting the bottom of both ends of the block and the base, and the two ends of the lifting cylinder are rotatably connected to the block and the base respectively, wherein the inner side of the lifting cylinder is provided with positioning grooves distributed along the length direction of the base, and a positioning mechanism is installed on the base, wherein the positioning roller at the free end of the positioning mechanism is adapted to the positioning groove.

[0010] Preferably, the positioning mechanism includes a driving rod, one end of which is rotatably mounted on the base, and the other end of which is rotatably mounted with a positioning roller, and the side of the driving rod close to the lifting cylinder is connected to the base through the positioning cylinder.

[0011] By adopting the above technical solution, when the lifting cylinder is started to adjust the height of the block, it drives the block to rise and fall and cooperates with the linkage mechanism between the blocks to move synchronously. When the blocks in the platform body are all in a horizontal state, the positioning roller in the positioning mechanism cooperates with the positioning groove on the side of the lifting cylinder to fix the position of the lifting cylinder. At this time, the lifting cylinder cannot rotate. When the lifting cylinder needs to cooperate with the linkage mechanism on the block for adjustment, the positioning cylinder in the positioning mechanism pushes the driving rod to rotate around its rotating connection point with the base through the extension and contraction of the piston rod. The rotation of the driving rod makes the positioning roller move away from the positioning groove on the inner side of the lifting cylinder to achieve unlocking. When the lifting cylinder needs to be positioned, the positioning cylinder extends the piston rod, the driving rod rotates, and the positioning roller is embedded in the positioning groove to achieve positioning.

[0012] Preferably, an adjustment groove is opened on the top of the side plate, wherein an adjustment plate horizontally installed in the adjustment groove passes through the side through-hole of the adjustment groove close to the block side and is fixedly connected to the block at the end, wherein an adjustment baffle is also installed on the end of the adjustment plate located in the adjustment groove, the outer diameter of the adjustment baffle is larger than the inner diameter of the side through-hole, and an adjustment cylinder is also installed between the adjustment baffle and the adjustment groove.

[0013] By adopting the above technical solution, when the linkage mechanism between the blocks and the lifting mechanism at the bottom are adjusted, the blocks in the platform body need to be fine-tuned, the adjusting cylinder starts to work, and the piston rod of the adjusting cylinder is extended and retracted to push or pull the adjusting baffle. Since the adjusting baffle is connected to the adjusting plate, and the adjusting plate is fixed to the block at the end, the movement of the adjusting baffle will drive the adjusting plate to slide horizontally in the adjusting groove. The sliding of the adjusting plate causes the position of the end block connected to it to change, thereby adapting to the adjustment of the shape change of the block in the platform body. The outer diameter of the adjusting baffle is larger than the inner diameter of the side perforation. This design ensures that the adjusting plate will not detach when sliding in the adjusting groove. At the same time, the precise control of the adjusting cylinder can achieve fine position adjustment of the block, and cooperate with the overall shape adjustment completed by the platform body through the lifting mechanism and the linkage mechanism, so that the platform can more perfectly fit various complex shapes of adsorption objects, further improving the platform's adaptability to different working conditions and the accuracy of adsorption.

[0014] Preferably, a locking hole is opened on the locking block along the axis of the rotating shaft, and the locking hole cooperates with the locking rod at the output end of the locking motor on the side of the placement slot for locking, and a locking groove cooperating with the locking rod is opened at one end of the placement slot away from the locking motor.

[0015] By adopting the above technical solution, before the shape of the platform body is adjusted through the linkage mechanism, the locking rod at the output end of the locking motor cooperates with the locking hole to lock the position of the rotating shaft, and a locking hole is opened on the locking block along the axis of the rotating shaft to cooperate with the locking rod, and the locking rod passes through the locking hole and cooperates with the locking groove in the placement groove to achieve locking when the block is in an overall horizontal state. This locking process ensures that the position of the rotating shaft is fixed in the sleeve, thereby preventing the angle between the blocks from changing due to external forces or other factors, and maintaining the stability of the initial state of the platform body. In the subsequent adsorption work, the stable initial platform body shape can make the subsequent adjustment of the platform body more precise, allowing the adsorption mechanism to play a better role, ensuring that the adsorption object is accurately and stably adsorbed, and effectively improving the reliability and stability of the platform work.

[0016] Preferably, the fixed section is adapted to the through hole on the block, and a rack is symmetrically provided on the side of the fixed section, a micro motor for driving the fixed end is installed in the side wall of the through hole, and a driven gear meshing with the rack is installed on the other side of the fixed section.

[0017] Preferably, a mounting groove is provided on one side of the through hole close to the adsorption hole, wherein the mounting groove is used to install the rotating section, and the inner diameter of the mounting groove gradually increases from the end of the through hole to the surface of the block, the bottom of the rotating section is rotatably connected to the fixed section through a fine-tuning mechanism, and the top of the rotating section is integrally formed with a mounting seat for installing the suction nozzle, wherein the inner diameter of the mounting seat is the same as that of the fixed section and the mounting section, and a limiting ring is provided at the end of the outer surface of the mounting seat, the outer side of the limiting ring adopts an arc structure, and the inner side adopts a right-angle structure, and a groove matching the limiting ring is provided on the inner wall of the suction nozzle.

[0018] Preferably, the fine-tuning mechanism includes an arc-shaped groove opened at the bottom of the rotating section, an arc-shaped rack is provided in the arc-shaped groove, a driving gear meshing with the arc-shaped rack is installed at the bottom of the arc-shaped groove, and the driving gear is driven by a fine-tuning motor, and fine-tuning cylinders connected to the top of the fixed end are also installed on both sides of the arc-shaped groove at the bottom of the rotating section, wherein the fine-tuning cylinders are rotatably connected to the rotating section and the fixed end.

[0019] Preferably, sealing ring grooves are provided on the end surface of the free end of the mounting seat and the end surface of the rotating section located around the mounting seat, and corresponding sealing protrusions are provided on the inner wall of the suction nozzle.

[0020] By adopting the above technical solution, when it is necessary to adjust the position of the adsorption body more accurately, the micro-motor is started, and the gear on its output shaft meshes with the gear on the side of the fixed section for transmission. At the same time, the rack on the other side of the fixed section rotates in coordination with the driven gear, so that the fixed section moves in the perforation of the block along the direction of the rack, and the precise position of the adsorption body on the block is fine-tuned to better align with the specific part of the adsorption object. During the adsorption process, if it is necessary to fine-tune the angle of the elastic suction nozzle, the fine-tuning motor starts to work, driving the driving gear to rotate and cooperate with the arc-shaped rack in the arc-shaped groove, driving the rotating section to rotate around the connection point with the fixed section. At the same time, the fine-tuning cylinder is extended and retracted according to actual needs, and through the rotation connection with the rotating section and the fixed end, the rotation angle of the rotating section is assisted to adjust, so that the elastic suction nozzle can better fit the complex shape of the surface of the adsorption object, further improving the accuracy of adsorption. When installing the suction nozzle, align the groove on the inner wall of the suction nozzle with the limit ring at the end of the outer surface of the mounting seat. Since the outer side of the limit ring is an arc structure, it is convenient for the installation of the suction nozzle. When the nozzle is inserted into place, the right-angle structure on the inner side of the limit ring cooperates with the groove to limit the axial movement of the nozzle and ensure that the nozzle is installed firmly. The sealing ring groove on the free end face of the mounting seat and the rotating section on the surrounding end faces of the mounting seat closely cooperates with the sealing protrusion on the inner wall of the nozzle, further enhancing the sealing effect during the adsorption process, preventing air leakage, and ensuring that the adsorption object can be more stably and firmly adsorbed on the elastic nozzle under the negative pressure generated by the vacuum pump, thereby improving the overall working performance and reliability of the adsorption mechanism.

[0021] Preferably, a visual positioning mechanism is also installed on one side of the platform body, wherein the visual positioning mechanism includes a CCD camera and a PLC controller, and the PLC controller is signal-connected with the lifting cylinder, adjusting cylinder, locking motor, micro motor, telescopic mechanism, positioning cylinder, fine-tuning motor and fine-tuning cylinder.

[0022] By adopting the above technical solution, the work starts, the CCD camera in the visual positioning mechanism is turned on, and the curved OLED panel placed on the platform body is photographed. After the CCD camera obtains the image information of the adsorption object, it transmits it to the PLC controller. The PLC controller analyzes and processes the image to identify the shape, position and key feature points of the adsorption object. Based on these analysis results, the PLC controller issues control instructions to each execution component according to the preset program. When it is determined that the shape of the platform body needs to be adjusted to adapt to the adsorption object, the PLC controller first contacts the locking motor to lock the rotating shaft on the block. The PLC controller sends a signal to the lifting cylinder, the positioning cylinder and the telescopic mechanism in the linkage mechanism to control the lifting cylinder to realize the lifting of the block. The positioning cylinder cooperates to ensure the lifting accuracy, and the telescopic mechanism cooperates with the rotating shaft and the locking block to form a suitable angle between the blocks. If the position or angle of the adsorption mechanism needs to be fine-tuned, the PLC controller will issue instructions to the micro-motor, the fine-tuning motor and the fine-tuning cylinder to accurately control the position of the adsorption body and the angle of the elastic suction nozzle. During the entire process, the visual positioning mechanism monitors the status of the adsorption object in real time, and the PLC controller continuously adjusts the various execution components so that the platform body and the adsorption mechanism can quickly and accurately adapt to the adsorption object, greatly improving the automation and accuracy of the adsorption operation.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The shape of this application is highly adaptable. The platform body is composed of multiple blocks connected by a linkage mechanism. The shape can be flexibly adjusted to adapt to different adsorption objects, expanding the scope of application;

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-8 This application is described in further detail.

[0037] The embodiment of the present application discloses a raised vacuum adsorption platform.

[0038] Reference Figure 1-Figure 8A raised vacuum adsorption platform comprises a platform body 1, the platform body 1 comprises a plurality of blocks 2, the bottom of the blocks 2 is rotatably connected to a base 22 through a lifting mechanism 21, and the two ends of the base 22 are movably connected to the blocks 2 at the end through side plates 23, wherein the blocks 2 are connected through a linkage mechanism 3, the linkage mechanism 3 can drive the blocks 2 to form different angles, an adsorption mechanism 4 is arrayed on the blocks 2, and the adsorption mechanism 4 is externally connected to a vacuum pump through a pipeline; a linkage mechanism 3, the linkage mechanism 3 comprises a plurality of groups of rotating shafts 31 and sleeves 32 connected between adjacent blocks 2, wherein the sleeves 32 are fixedly installed at the top corners of the blocks 2, an arc groove 24 adapted to the sleeves 32 is opened on the adjacent blocks 2, and the sleeves 32 on a single block 2 are located at the end of a single diagonal line on the cross section of the block 2; a side of the rotating shaft 31 is provided There is a protruding locking block 311, and the end of the locking block 311 away from the shaft sleeve 32 is connected to the adjacent block 2 through a telescopic mechanism 33, and the two ends of the telescopic mechanism 33 are respectively rotatably connected to the locking block 311 and the block 2, and a placement groove 25 for accommodating the locking block 311 and the telescopic mechanism 33 is opened on the block 2; the adsorption mechanism 4, the adsorption mechanism 4 includes an adsorption body 41 and an elastic suction nozzle 42 installed at the output end of the adsorption body 41, and the back of the adsorption body 41 is connected to the vacuum pump through an adsorption pipe 43, wherein the adsorption body 41 adopts a multi-section pipe structure, including a fixed section 411 slidably connected to the block 2, and a rotating section 412 is installed at the output end of the fixed section 411, wherein the rotating section 412 is connected to the fixed section 411 through a telescopic tube body 413, and the free end of the rotating section 412 is detachably installed with an elastic suction nozzle 42. During operation, when the shape of the platform body 1 needs to be adjusted to adapt to the adsorption objects of different shapes, the lifting mechanism 21 can be controlled to make the block 2 perform lifting and lowering actions around the rotation connection point with the base 22. Since the blocks 2 are connected by the linkage mechanism 3, the linkage mechanism 3 plays a role in the lifting process. Taking one group of adjacent blocks 2 as an example, when the position of one block 2 changes relative to another block 2, the rotating shaft 31 rotates in the shaft sleeve 32, and at the same time, the locking block 311 moves with the rotation of the rotating shaft 31, and the telescopic mechanism 33 is correspondingly extended and retracted according to the change of the angle between the blocks 2, thereby ensuring that the linkage mechanism 3 stably drives the blocks 2 to form different angles, and realizes the flexible adjustment of the overall shape of the platform body 1. In the adsorption working stage, the vacuum pump is started, and the adsorption mechanism 4 is generated through the adsorption pipe 43. The fixed section 411 of the adsorption body 41 is slidably connected with the block 2, so that the adsorption body 41 can adjust its position in the block 2 according to actual needs, and the suction nozzle 42 can adjust the height of the protruding block 2 surface according to needs. When the OLED panel is placed on the platform, the elastic suction nozzle 42 first contacts the surface of the adsorption object. Since the elastic suction nozzle 42 is elastic, it can fit the surface of the OLED panel well to ensure a sealed adsorption effect.The rotating section 412 is connected to the fixed section 411 through the telescopic tube 413, and can be flexibly rotated to further adapt to the curved OLED panel structure, so that the elastic suction nozzle 42 can be more accurately adsorbed at the target position. The platform body 1 is composed of a number of blocks 2 and connected by a linkage mechanism 3. It can flexibly adjust the surface shape of the platform according to the different curved structures of the OLED panel, greatly expanding the scope of application of the platform. The adsorption mechanism 4 adopts a multi-section pipeline structure, combined with the design of the elastic suction nozzle 42 and the rotating section 412 and the telescopic tube 413, which enhances the adsorption capacity of the adsorption mechanism 4 for adsorption objects of different shapes and surface conditions, and improves the stability and reliability of adsorption. In addition, the bottom of the block 2 is rotatably connected to the base 22 through the lifting mechanism 21, which not only helps to adjust the overall shape of the platform, but also can achieve fine-tuning of the height of the adsorption object to a certain extent, further improving the functionality and practicality of the platform.

[0039] Reference Figure 1-Figure 8 The lifting mechanism 21 includes a lifting cylinder 211 connecting the bottom of both ends of the block 2 and the base 22. The two ends of the lifting cylinder 211 are rotatably connected to the block 2 and the base 22 respectively. The inner side of the lifting cylinder 211 is provided with a positioning groove 212 distributed along the length direction of the base 22. The base 22 is provided with a positioning mechanism 5, wherein the positioning roller 52 at the free end of the positioning mechanism 5 is adapted to the positioning groove 212. The positioning mechanism 5 includes a driving rod 51, one end of the driving rod 51 is rotatably mounted on the base 22, and the other end is rotatably mounted with a positioning roller 52. The side of the driving rod 51 close to the lifting cylinder 211 is connected to the base 22 through a positioning cylinder 53. When the lifting cylinder 211 is started to adjust the height of the block 2, it drives the block 2 to rise and fall and cooperates with the linkage mechanism 3 between the blocks 2 to move synchronously. When the blocks 2 in the platform body 1 are all in a horizontal state, the positioning roller 52 in the positioning mechanism 5 cooperates with the positioning groove 212 on the side of the lifting cylinder 211 to fix the position of the lifting cylinder 211. At this time, the lifting cylinder 211 cannot rotate. When the lifting cylinder 211 needs to cooperate with the linkage mechanism 3 on the block 2 for adjustment, the positioning cylinder 53 in the positioning mechanism 5 pushes the driving rod 51 to rotate around the rotation connection point between it and the base 22 through the extension and contraction of the piston rod. The rotation of the driving rod 51 makes the positioning roller 52 away from the positioning groove 212 on the inner side of the lifting cylinder 211 to achieve unlocking. When the lifting cylinder 211 needs to be positioned, the positioning cylinder 53 extends the piston rod, the driving rod 51 rotates, and the positioning roller 52 is embedded in the positioning groove 212 to achieve positioning.

[0040] Reference Figure 1-Figure 8, an adjustment groove 231 is provided at the top of the side plate 23. An adjustment plate 232 horizontally installed in the adjustment groove 231 penetrates through a side perforation 27 on the side close to the block 2 and is fixedly connected to the end block 2. An adjustment baffle 233 is further installed at the end of the adjustment plate 232 located in the adjustment groove 231. The outer diameter of the adjustment baffle 233 is larger than the inner diameter of the side perforation 27. An adjustment cylinder 234 is also installed between the adjustment baffle 233 and the adjustment groove 231. When the linkage mechanism 3 between the blocks 2 and the lifting mechanism 21 at the bottom are adjusted, it is necessary to finely adjust the block 2 inside the platform main body 1. The adjustment cylinder 234 starts to work, and the piston rod of the adjustment cylinder 234 expands and contracts to push or pull the adjustment baffle 233. Since the adjustment baffle 233 is connected to the adjustment plate 232, and the adjustment plate 232 is fixedly connected to the end block 2, the movement of the adjustment baffle 233 will drive the adjustment plate 232 to slide horizontally in the adjustment groove 231. The sliding of the adjustment plate 232 causes the position of the end block 2 connected to it to change, thus adapting to the adjustment of the shape change of the block 2 in the platform main body 1. The outer diameter of the adjustment baffle 233 is larger than the inner diameter of the side perforation 27. This design ensures that the adjustment plate 232 will not break away when sliding in the adjustment groove 231. At the same time, with the precise control of the adjustment cylinder 234, the block 2 can achieve fine position adjustment, cooperating with the overall shape adjustment completed by the platform main body 1 through the lifting mechanism 21 and the linkage mechanism 3, enabling the platform to better fit various complex-shaped adsorption objects, further improving the adaptability of the platform to different working conditions and the accuracy of adsorption.

[0041] Refer to Figure 1-Figure 8 , a locking hole is provided along the axis direction of the rotating shaft 31 on the locking block 311. The locking hole cooperates with the locking rod 261 at the output end of the locking motor 26 on the side of the placement groove 25 for locking, and a locking groove 251 cooperating with the locking rod 261 is provided at one end of the placement groove 25 away from the locking motor 26. Before the platform main body 1 adjusts its shape through the linkage mechanism 3, the position of the rotating shaft 31 is in a locked state with the cooperation of the locking rod 261 at the output end of the locking motor 26 and the locking hole. A locking hole is provided along the axis direction of the rotating shaft 31 on the locking block 311 to cooperate with the locking rod 261, and the locking rod 261 passes through the locking hole and cooperates with the locking groove 251 in the placement groove 25 for fixation, realizing the locking of the block 2 when it is in an overall horizontal state. This locking process ensures the fixed position of the rotating shaft 31 in the shaft sleeve 32, thereby preventing the angle between the blocks 2 from changing due to external forces or other factors and maintaining the stability of the initial state of the platform main body 1. In subsequent adsorption work, the stable initial shape of the platform main body 1 can make the subsequent adjustment of the platform main body 1 more accurate, enable the adsorption mechanism 4 to play a better role, ensure that the adsorption object is accurately and stably adsorbed, and effectively improve the reliability and stability of the platform work.

[0042] Refer to Figure 1-Figure 8The fixed section 411 is adapted to the through hole 27 on the block 2, and a rack 4111 is symmetrically provided on the side of the fixed section 411. A micro motor 271 for driving the fixed end is installed in the side wall of the through hole 27, and a driven gear 272 meshing with the rack 4111 is installed on the other side of the fixed section 411. A mounting groove 273 is provided on one side of the through hole 27 close to the adsorption hole, wherein the mounting groove 273 is used to install the rotating section 412, and the inner diameter of the mounting groove 273 gradually increases from the end of the through hole 27 to the surface of the block 2, the bottom of the rotating section 412 is rotatably connected to the fixed section 411 through the fine-tuning mechanism 6, and the top of the rotating section 412 is integrally formed with a mounting seat 4131 for installing the suction nozzle 42, wherein the inner diameter of the mounting seat 4131 is the same as that of the fixed section 411 and the mounting section, and a limiting ring 4132 is provided at the end of the outer surface of the mounting seat 4131, the outer side of the limiting ring 4132 adopts an arc structure, and the inner side adopts a right-angle structure, and a groove adapted to the limiting ring 4132 is provided on the inner wall of the suction nozzle 42. The fine-tuning mechanism 6 includes an arc groove 61 provided at the bottom of the rotating section 412, an arc rack 4111 is provided in the arc groove 61, a driving gear 62 meshing with the arc rack 4111 is installed at the bottom of the arc groove 61, and the driving gear 62 is driven by a fine-tuning motor 63, and fine-tuning cylinders 64 connected to the top of the fixed end are also installed on both sides of the arc groove 61 at the bottom of the rotating section 412, wherein the fine-tuning cylinder 64 is rotatably connected to the rotating section 412 and the fixed end. The end surface of the free end of the mounting seat 4131 and the end surface of the rotating section 412 located around the mounting seat 4131 are both provided with sealing ring grooves 7, and a corresponding sealing protrusion is provided on the inner wall of the suction nozzle 42. When it is necessary to adjust the position of the adsorption body 41 more accurately, the micro-motor 271 is started, and the gear on its output shaft meshes with the gear on the side of the fixed section 411 for transmission. At the same time, the rack 4111 on the other side of the fixed section 411 cooperates with the driven gear 272 to rotate, so that the fixed section 411 moves in the perforation 27 of the block 2 along the direction of the rack 4111, and the precise position of the adsorption body 41 on the block 2 is fine-tuned to better align with the specific part of the adsorption object. During the adsorption process, if it is necessary to fine-tune the angle of the elastic suction nozzle 42, the fine-tuning motor 63 starts to work, driving the driving gear 62 to rotate and cooperate with the arc-shaped rack 4111 in the arc-shaped groove 61, driving the rotating section 412 to rotate around the connection point with the fixed section 411, and at the same time, the fine-tuning cylinder 64 is extended and retracted according to actual needs, and through the rotation connection with the rotating section 412 and the fixed end, the rotation angle of the rotating section 412 is assisted to adjust, so that the elastic suction nozzle 42 can better fit the complex shape of the surface of the adsorption object, further improving the accuracy of adsorption. When installing the suction nozzle 42, align the groove on the inner wall of the suction nozzle 42 with the limiting ring 4132 on the end of the outer surface of the mounting seat 4131. Since the outer side of the limiting ring 4132 is an arc-shaped structure, it is convenient for the suction nozzle 42 to be installed. When the suction nozzle 42 is inserted into place, the right-angle structure on the inner side of the limiting ring 4132 cooperates with the groove to limit the axial movement of the suction nozzle 42, ensuring that the suction nozzle 42 is firmly installed.The sealing ring groove 7 located on the free end face of the mounting seat 4131 and the rotating section 412 and the end face around the mounting seat 4131 closely cooperates with the sealing protrusion on the inner wall of the suction nozzle 42, further enhancing the sealing effect during the adsorption process and preventing air leakage. This ensures that under the negative pressure generated by the vacuum pump, the adsorbed object can be more stably and firmly adsorbed on the elastic suction nozzle 42, thereby improving the overall working performance and reliability of the adsorption mechanism 4.

[0043] Reference Figure 1-Figure 8 , a visual positioning mechanism 8 is also installed on one side of the platform body 1, wherein the visual positioning mechanism 8 includes a CCD camera and a PLC controller 81, and the PLC controller 81 is signal-connected with the lifting cylinder 211, the adjusting cylinder 234, the locking motor 26, the micro-motor 271, the telescopic mechanism 33, the positioning cylinder 53, the fine-tuning motor 63 and the fine-tuning cylinder 64. At the beginning of the work, the CCD camera in the visual positioning mechanism 8 is turned on to shoot the curved OLED panel placed on the platform body 1. After the CCD camera obtains the image information of the adsorbed object, it transmits it to the PLC controller 81. The PLC controller 81 analyzes and processes the image to identify the shape, position and key feature points of the adsorbed object. Based on these analysis results, the PLC controller 81 issues control instructions to each execution component according to the preset program. When it is determined that the shape of the platform body 1 needs to be adjusted to adapt to the adsorption object, the PLC controller 81 first contacts the locking motor 26 to lock the rotating shaft 31 on the block 2, and the PLC controller 81 sends a signal to the lifting cylinder 211, the positioning cylinder 53 and the telescopic mechanism 33 in the linkage mechanism 3 to control the lifting cylinder 211 to realize the lifting of the block 2, the positioning cylinder 53 cooperates to ensure the lifting accuracy, and the telescopic mechanism 33 cooperates with the rotating shaft 31 and the locking block 311 to form a suitable angle between the blocks 2. If it is necessary to fine-tune the position or angle of the adsorption mechanism 4, the PLC controller 81 will issue instructions to the micro-motor 271, the fine-tuning motor 63 and the fine-tuning cylinder 64 to accurately control the position of the adsorption body 41 and the angle of the elastic suction nozzle 42. During the whole process, the visual positioning mechanism 8 monitors the state of the adsorption object in real time, and the PLC controller 81 continuously adjusts each execution component so that the platform body 1 and the adsorption mechanism 4 can quickly and accurately adapt to the adsorption object, greatly improving the automation and accuracy of the adsorption operation.

[0044] Working principle: When working, first adjust the shape of the platform. According to the shape of the adsorbed OLED panel, operate the lifting mechanism 21 to allow the block 2 to rotate and lift around the base 22. The linkage mechanism 3 between the blocks 2 operates, the shaft 31 rotates on the sleeve 32, the locking block 311 moves, and the telescopic mechanism 33 stretches and contracts, so that the block 2 forms different angles, and the shape of the platform body 1 can be flexibly adjusted. Then the adsorption operation is carried out, the vacuum pump is started, and the fixed section 411 of the adsorption body 41 slides and positions on the block 2 according to the actual situation. The elastic suction nozzle 42 contacts the surface of the adsorption object, and the rotating section 412 rotates flexibly with the telescopic tube 413 to accurately fit the complex surface. The vacuum pump generates negative pressure, and the adsorption object is adsorbed on the elastic suction nozzle 42 through the adsorption pipe 43.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
