Description

Technical Field

[0001] This application relates to the field of auxiliary equipment for display device processing, and in particular to a display panel transfer device and processing system. Background Technology

[0002] Currently, inkjet printing technology has broad application prospects in manufacturing fields such as information, energy, medical, and defense. In recent years, it has been increasingly applied to flexible devices such as OLED, RFID, thin-film solar cells, wearable flexible devices, PCB, smart skin, and LED direct-view displays.

[0003] The substrate inkjet printing process involves multiple steps, including cleaning, printing, drying, and baking. The substrate must be moved into a processing chamber and transferred between multiple chambers to complete the processing.

[0004] Among them, reference Figure 1 and Figure 2 The process chamber 5 includes a feed inlet 5a. To precisely control the atmosphere within the process chamber 5, the opening height of the feed inlet 5a is relatively small. A support platform 51 is arranged inside the process chamber 5. The support platform 51 is composed of a mounting plate 511 and multiple support blocks 512. The multiple support blocks 512 are spliced ​​and installed on the mounting plate 511, and there is a gap between the multiple support blocks 512.

[0005] During substrate printing, the substrate needs to be transferred and delivered to the process chamber. In related technologies, manual loading is required during the initial testing and debugging of the substrate processing equipment to deliver the substrate to the process chamber.

[0006] However, when processing large-size substrates, on the one hand, the process chamber is large in size and the feed port of the process chamber is high, making it difficult for manual labor to send the substrate into the process chamber; on the other hand, the substrate is too large, making it difficult for manual picking up, requiring multiple people to handle it, and the substrate is subjected to uneven force, which can easily lead to concentrated force on the edges and damage. Summary of the Invention

[0007] This application provides a display panel transfer device and processing system to solve the technical problems in the related art, such as the difficulty in manually transporting large-size substrates to high-altitude process cabins, and the tendency for manual handling of substrates to cause stress concentration at the substrate edges and damage to the substrate.

[0017] In some embodiments, the bottom surface of the conveyor plate is provided with multiple air outlets, all of which are connected to an external air supply device, and the air outlets support the conveyor plate by releasing air.

[0018] In some embodiments, the suction cup is elastically mounted to the conveyor plate, and the elastic movement direction of the suction cup is vertical; wherein,

[0019] When the conveying substrate is not placed on the support frame, the suction surface of the suction cup is higher than the highest point of the rollers of the first roller group;

[0020] When the substrate is placed on the support frame and supported by the first roller group, the suction cup elastically descends, and the suction surface of the suction cup is flush with the rollers of the first roller group.

[0021] In some embodiments, the display panel transfer device further includes a nitrogen spring, which is vertically arranged, with its fixed end mounted on the vehicle body and its driving end connected to the support frame.

[0022] In some embodiments, the lifting drive assembly includes:

[0023] The belt mechanism has both its driving and driven pulleys rotatably connected to the vehicle body. The belt of the belt mechanism is vertically oriented, and the support frame is fixed to the belt of the belt mechanism.

[0024] A rotating rod is fixed to the rotation shaft of the drive wheel of the belt mechanism, and the belt mechanism is driven to run by rotating the rotating rod.

[0025] In some embodiments, the lifting drive assembly further includes a locking assembly, the locking assembly comprising:

[0026] A locking disc is fixed to the vehicle body. The rotating shaft of the drive wheel of the belt mechanism passes through the locking disc coaxially. The surface of the locking disc is provided with a plurality of locking holes, which are evenly distributed circumferentially around the center line of the locking disc.

[0027] A locking spring pin is mounted on the rotating rod and is adapted to be inserted into the locking hole.

[0035] This application provides a display panel transfer device. When transferring a substrate to the process compartment, the substrate is placed on a support frame and supported by a first set of rollers. The substrate is then moved from the support frame to the process compartment by pushing a trolley, replacing manual handling. This method results in more even force distribution on the substrate and reduces the risk of damage due to localized stress on the edges. A lifting drive assembly then raises the support frame to the height of the process compartment's inlet, pushing the substrate on the first set of rollers. The first set of rollers facilitates the easy pushing of the substrate into the process compartment, eliminating the need for manual delivery and requiring no manual intervention.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] This application provides a display panel transfer device and processing system. The display panel transfer device uses a first roller assembly on a support frame to support the substrate, and a pusher to transfer the substrate. A lifting drive assembly then raises the support frame and the substrate, and finally, the substrate is pushed from the inlet into the process chamber. Therefore, the substrate transfer process is characterized by uniform force distribution, minimizing damage, and facilitates lifting the substrate to the height of the inlet. The first roller assembly allows for easy direct pushing of the substrate through the inlet, avoiding the limitations of the inlet's size that could affect loading. This application addresses the technical problems in related technologies where large-size substrates are difficult to manually transport to higher process chambers, and where manual handling of substrates easily leads to concentrated force on the substrate edges, causing damage.

[0054] Reference Figure 3 A display panel transfer device includes a vehicle body 1, a support component 2, and a lifting drive component 3. The support component 2 supports a substrate a and is slidably mounted on the vehicle body 1. The lifting drive component 3 is mounted on the vehicle body 1 and is drivenly connected to the support component 2 to drive the support component 2 to move up and down. By pushing the vehicle body 1, the substrate a on the support component 2 can be transferred, facilitating the delivery of the substrate a to the process compartment 5. The lifting drive component 3 then lifts the support component 2 and the substrate a, raising the substrate a to the height of the inlet 5a of the process compartment 5, thus facilitating the pushing of the substrate a on the support platform 51 inside the process compartment 5 through the inlet 5a.

[0055] With this configuration, the substrate a is transferred using a pushcart 1, eliminating the need for manual handling. This not only facilitates the transport of substrate a but also reduces the risk of damage from concentrated stress. The lifting drive assembly 3 elevates the height of the support assembly 2 and substrate a, making it easy to lift substrate a to the feed inlet 5a of the process compartment 5.

[0056] It should be noted that the process chamber 5 required for processing large-size substrates a is relatively large, and the height of the feed port 5a is also relatively high. Generally, the substrate a processed by the G6 production line is 1500*1850mm in size, and the height of its process chamber 5 feed port 5a is nearly two meters. Therefore, it is difficult for a person to manually feed the substrate a from the feed port 5a into the process chamber 5.

[0057] The rear end of the vehicle body 1 is equipped with a handle to facilitate pushing the vehicle body 1. In this embodiment, the front and rear ends of the vehicle body 1 are arranged in a first direction, which is the X-axis direction in the figure.

[0058] Reference Figure 1 and Figure 2It should be noted that the vehicle body 1 is pushed to place the vehicle body 1 in the process compartment 5. The process compartment 5 has a feed port 5a on its side, and a support platform 51 is arranged inside the process compartment 5. The support platform 51 consists of multiple support blocks 512 and a mounting plate 511. The mounting plate 511 is installed inside the process compartment 5, and the multiple support blocks 512 are installed at intervals on the mounting plate 511. The support blocks 512 can be set to adsorb the substrate a, so as to facilitate subsequent processing of the fixed substrate a.

[0059] When the vehicle body 1 moves to the side of the process compartment 5, the supporting component 2 and the substrate a rise, so that the substrate a is placed at the height of the feed port 5a, which makes it convenient to push the substrate a into the process compartment 5.

[0060] Reference Figure 1 Furthermore, a positioning rod 52 is fixed on one side of the feed inlet 5a of the process compartment 5. There are two positioning rods 52, which are spaced apart and are vertically positioned.

[0061] Reference Figure 3 and Figure 4 The vehicle body 1 also includes a positioning component 11, which includes two positioning seats. Both positioning seats are connected to the front end face of the vehicle body 1, and the two positioning seats are spaced apart in a second direction. In this embodiment, the second direction is perpendicular to the first direction, and the second direction is the Y-axis direction in the figure.

[0062] Reference Figure 3 and Figure 4 The front end face of the positioning seat is provided with a positioning groove 11a, which is flared when viewed from above. When the vehicle body 1 moves to the process compartment 5, both positioning seats are engaged with the two positioning rods 52 through the positioning groove 11a respectively, thereby positioning the vehicle body 1 and the process compartment 5. The relative position of the positioning support component 2 and the process compartment 5 ensures that the substrate is always loaded at the same position.

[0063] Reference Figure 3 and Figure 7 The supporting assembly 2 includes a support frame 21 and a first roller assembly 22. The support frame 21 is located above the vehicle body 1 and is slidably mounted on the vehicle body 1. Specifically, the support frame 21 is slidably mounted on the vehicle body 1 via multiple guide rods or linear bearings. The first roller assembly 22 is arranged on the support frame 21, and multiple rollers of the first roller assembly 22 are rotatably mounted on the support frame 21, with the rotation axis of the rollers of the first roller assembly 22 arranged along a second direction. The first roller assembly 22 is used to support the base plate a.

[0064] During loading, the support frame 21 is raised to the height of the feed inlet 5a, at which point the substrate a is pushed to move in the first direction so that the substrate a slides on the first roller assembly 22 and enters the process chamber 5. As the substrate a is pushed in the first direction, the multiple rollers of the first roller assembly 22 rotate.

[0065] This configuration utilizes multiple rollers of the first roller group 22 to support the substrate a, resulting in more even force distribution on the substrate a and reducing the likelihood of deformation or damage during transport. Furthermore, when pushing the substrate a, the rotation of the multiple rollers in the first roller group 22 reduces friction, making it easier to push the substrate a into the process chamber 5. Additionally, the bottom surface of the substrate a is less prone to scratches, ensuring substrate quality.

[0066] In this embodiment, preferably, the material of the multiple rollers of the first roller group 22 is plastic, which is not only lightweight, but also less likely to scratch the substrate a.

[0067] Reference Figure 3 and Figure 7 Furthermore, the support assembly 2 also includes two sets of second roller groups 23. Multiple rollers of the second roller groups 23 are arranged in a row along the first direction, and the rotation axes of the multiple rollers of the second roller groups 23 are vertically aligned. The circumferential sides of the multiple rollers of the second roller groups 23 are adapted to contact the sides of the substrate a. The two sets of second roller groups 23 are respectively located near the opposite edges of the support frame 21 in the second direction. The second roller groups 23 are used to restrict the movement direction of the substrate a, ensuring that the substrate a moves along the first direction, and preventing the substrate a from slipping off the sides of the support frame 21 during transport.

[0068] In this embodiment, the rollers of the second roller assembly 23 are made of metal, such as an alloy. Because the substrate is thin and its sides are relatively sharp, making the second roller assembly 23 of metal makes it less prone to scratches.

[0069] Reference Figure 7 and Figure 10 Furthermore, the supporting assembly 2 also includes a blocking assembly 25, which includes a baffle plate 251 and a blocking spring pin 252. The baffle plate 251 is rotatably connected to the front end of the supporting frame 21 and is used to block the substrate a to prevent the substrate a from sliding off the front end of the supporting frame 21. The blocking spring pin 252 is mounted on the baffle plate 251. A connecting hole is provided on the front end face of the supporting frame 21, and the blocking spring pin 252 is adapted to be inserted into the connecting hole to restrict the rotation of the baffle plate 251 and keep the baffle plate 251 in the blocking state.

[0070] Specifically, when the stop spring pin 252 is inserted into the connection hole, the highest point of the stop plate 251 is higher than the highest point of the first roller group 22. At this time, the stop plate 251 is in a blocking state, which restricts the base plate a from sliding off the front end of the support frame 21.

[0071] When the stop spring pin 252 disengages from the connection hole, the stop plate 251 rotates and falls below the highest point of the first roller assembly 22. At this time, the substrate a can be pushed, causing the substrate a to slide out from the front end of the support frame 21 and extend into the process chamber 5.

[0072] In this embodiment, there are two sets of barrier components 25. The two sets of barrier components 25 are respectively arranged near the opposite two edges of the front end face of the support frame 21, and the two sets of barrier components 25 are spaced apart in the second direction.

[0073] Reference Figure 3 and Figure 7 Furthermore, the support assembly 2 also includes a baffle plate 26, which is fixed to the rear end of the support frame 21, and the highest height of the baffle plate 26 is higher than the highest height of the rollers of the first roller assembly 22. After the substrate a is placed on the first roller assembly 22, the baffle plate 26 restricts the substrate a from sliding off the rear end of the support frame 21.

[0074] Reference Figure 3 and Figure 5 The lifting drive assembly 3 is installed on the vehicle body 1 and is connected to the load-bearing assembly 2 to drive the load-bearing assembly 2 to move up and down.

[0075] Specifically, the lifting drive assembly 3 includes a belt mechanism 31 and a rotating rod 32. Both the driving and driven pulleys of the belt mechanism 31 are rotatably connected to the vehicle body 1, and the belt of the belt mechanism 31 is vertically oriented. The support frame 21 is fixed to the belt of the belt mechanism 31. Therefore, by operating the belt mechanism 31, the lifting of the support frame 21 can be achieved.

[0076] The rotating rod 32 is coaxially fixed with the rotating shaft of the drive wheel of the belt mechanism 31, and the belt mechanism 31 is driven to run by rotating the rotating rod 32.

[0077] In other embodiments, the lifting drive assembly 3 may also include a lead screw mechanism or a linear motor.

[0078] Reference Figures 3-6 Furthermore, the lifting drive assembly 3 also includes a locking assembly 33, which is used to fix the position of the rotating rod 32 and restrict the rotation of the rotating rod 32 to maintain the height of the support frame 21. The locking assembly 33 includes a locking disc 331 and a locking spring pin 332.

[0079] The locking disc 331 is fixed to the side of the vehicle body 1. The rotation shaft of the drive wheel of the belt mechanism 31 passes coaxially through the locking disc 331. The surface of the locking disc 331 has multiple locking holes 331a, which are evenly distributed circumferentially around the center line of the locking disc 331. In this embodiment, the central angle between adjacent locking holes 331a is 15 degrees.

[0080] The locking spring pin 332 is mounted on the rotating rod 32, and the locking spring pin 332 is adapted to be inserted into the locking hole 331a.

[0081] With this configuration, when adjusting the height of the support frame 21, the locking spring pin 332 disengages from the locking hole 331a, allowing the rotating rod 32 to rotate relative to the locking disc 331, thus adjusting the support frame 21 to the desired height. After the height of the support frame 21 is adjusted, the locking spring pin 332 is inserted into a locking hole 331a, restricting the rotation of the rotating rod 32. This maintains the height of the support frame 21, facilitating the subsequent pushing of the substrate a on the support frame 21 into the process chamber 5. Furthermore, since multiple locking holes 331a are provided, the height at which the support frame 21 stops is more easily controlled, allowing the height of the substrate a to be slightly higher than the height of the support platform 51 inside the process chamber 5.

[0082] Reference Figure 5 Optionally, the display panel transfer device further includes a nitrogen spring 4. The nitrogen spring 4 is vertically arranged, with its fixed end mounted on the vehicle body 1 and its driving end connected to the support frame 21. The nitrogen spring 4 supports the support frame 21 and maintains the supporting force on the support frame 21 as the support frame 21 moves, that is, the nitrogen spring 4 offsets part of the weight of the support frame 21 and the upper substrate a.

[0083] With this configuration, the nitrogen spring 4 reduces the load on the lifting drive assembly 3, making it easier to lift the load-bearing assembly 2.

[0084] Reference Figure 7 Furthermore, the carrying assembly 2 also includes multiple conveying assemblies 24. Each conveying assembly 24 includes a conveying plate 241, a conveying drive component, and multiple suction cups 242. The conveying plate 241 is arranged along a first direction in its length direction, and the multiple conveying plates 241 are spaced apart in a second direction.

[0085] Reference Figure 7 and Figure 8 Specifically, the rear end of the conveyor plate 241 is slidably connected to the support frame 21, and the sliding direction of the conveyor plate 241 is set along the first direction. As the conveyor plate 241 slides, the conveyor plate 241 can extend to the upper side of the support frame 21, and most of the conveyor plate 241 can extend into the process compartment 5.

[0086] Reference Figure 7 and Figure 8 Multiple suction cups 242 are mounted on the conveyor plate 241, and each suction cup 242 is connected to an external negative pressure device. The suction surface of the suction cups 242 faces upward, and the suction surface of the suction cups 242 is flush with the highest point of the rollers of the first roller group 22. That is, after the substrate a is supported by the first roller group 22, the suction cups 242 will adsorb and fix the bottom surface of the substrate a.

[0087] A conveying drive (not shown) is mounted on the support frame 21 and is drivenly connected to the conveyor plate 241 to move the conveyor plate 241 in a first direction, causing the conveyor plate 241 to extend into the process chamber 5. In this embodiment, the conveying drive includes a cylinder, a lead screw mechanism, or a linear motor.

[0088] With this configuration, after substrate a is placed on the support frame 21, substrate a is supported by the first roller group 22 and the suction cup 242, and the suction cup 242 adsorbs and fixes substrate a. After the vehicle body 1 is moved to the process compartment 5 and the height of the support frame 21 is raised, the conveying drive unit drives the conveyor plate 241 to move towards the feed port 5a, and the conveyor plate 241 and the substrate a on the conveyor plate 241 can be extended together from the feed port 5a into the process compartment 5.

[0089] Since the conveyor plate 241 and the substrate a are connected by a suction cup 242, the combined thickness of the conveyor plate 241 and the substrate a is also relatively thin, which is suitable for the process chamber 5 with a small inlet 5a, making it convenient to automatically send the substrate a into the process chamber 5 with a small inlet 5a.

[0090] Reference Figure 11 and Figure 12 After the conveyor plate 241 enters the process chamber 5, it is positioned above the support platform 51, and its orthogonal projection onto the support platform 51 lies in the gap between the support blocks 512. Subsequently, the support frame 21 descends, simultaneously lowering the conveyor plate 241. The conveyor plate 241 then descends into the gap between adjacent support blocks 512, placing the substrate a onto the support platform 51. Therefore, even if the feed inlet 5a of the process chamber 5 is small, the substrate a can still be laid flat on the support platform 51, avoiding damage to the substrate a due to friction between the substrate a and the support platform 51.

[0091] The suction cup 242 is elastically connected to the conveyor plate 241, and the elastic movement direction of the suction cup 242 is set vertically.

[0092] Specifically, when substrate a is not placed on the support frame 21, the adsorption surface of the suction cup 242 is higher than the highest point of the rollers in the first roller group 22. This ensures that when substrate a is placed, substrate a can contact the suction cup 242, and that the suction cup 242 adsorbs and fixes substrate a.

[0093] When substrate a is placed on the support frame 21 and supported by the first roller group 22, the suction cup 242 elastically decreases, and the adsorption surface of the suction cup 242 is flush with the rollers of the first roller group 22. After the suction cup 242 is subjected to pressure from substrate a, the suction cup 242 elastically decreases, and the height of the adsorption surface of the suction cup 242 is flush with the highest point of the rollers of the first roller group 22, and substrate a is also supported by the first roller group 22.

[0094] Furthermore, the bottom surface of the conveyor plate 241 is provided with multiple air outlets, all of which are connected to an external air supply device through pipes. Air is released from the air outlets to support the conveyor plate 241.

[0095] With this configuration, since the rear end of the conveyor plate 241 is only slidably connected to the support frame 21, the conveyor plate 241 is in a cantilever beam state. Air is blown through the air outlet to support the conveyor plate 241, making it less prone to bending deformation. The suction cups 242 on the conveyor plate 241 are also less prone to height differences, thus providing flat support for the substrate a and preventing deformation or even breakage of the substrate a.

[0096] Furthermore, after the front end of the conveyor plate 241 extends above the support table 51, the air outlet of the conveyor plate 241 can still support the front end of the conveyor plate 241, and the conveyor plate 241 is not easily deformed. Therefore, during the process of the substrate a being fed onto the support table 51, the substrate a can be kept flat, the substrate a is not easily deformed, and there will be no situation where it is damaged due to deformation.

[0097] This application provides a display panel transfer device. When transferring substrate a to the process compartment 5, substrate a is placed on a support frame 21 and supported by a first roller assembly 22. By pushing the vehicle body 1, substrate a on the support frame 21 is transferred to the process compartment 5, replacing manual handling and transfer of substrate a. The substrate a is subjected to more even force and is less prone to damage due to localized force on the edges. Then, the lifting drive assembly 3 drives the support frame 21 to the height of the feed port 5a of the process compartment 5, and pushes the substrate a on the first roller assembly 22. Under the action of the first roller assembly 22, it is easier to push substrate a into the process compartment 5. There is no need for manual delivery of substrate a into the process compartment 5, and no hand needs to be reached into the process compartment 5 through the feed port 5a. The size of the feed port 5a does not affect the loading process of substrate a.

[0098] Another embodiment of this application provides a display panel processing system, including the display panel transfer device described above.

[0099] Another embodiment of this application provides a display panel processing system. Since the display panel processing system includes the display panel transfer device described above, the beneficial effects of the display panel processing system are the same as those of the display panel transfer device described above, and will not be repeated here.
