Description

Technical Field

[0001] This application belongs to the technical field of display panel production equipment, specifically relating to a display panel gripping robot and a display panel production line. Background Technology

[0002] With the increasing demand for high-definition displays and the growth of portable consumer devices, traditional CRT displays are gradually being replaced by thin and light flat panel displays. This has spurred research and commercialization of thin-film flat panel displays. The manufacturing process of flat panel displays, including processes such as deposition, photolithography, and etching, requires automated equipment to handle the display panels. Among these processes, display panel gripping robots play a crucial role, transferring the display panels to specific processing stations to complete production.

[0003] Existing display panel gripping robots mainly consist of a base, a rotating arm mounted on the base, and a mechanical gripper mounted on the rotating arm. The rotation of the rotating arm drives the mechanical gripper to grasp display panels at different workstations, thus transferring the panels. A reducer is installed between the rotating arm and the base. This reducer has a limited lifespan of approximately five years. When the reducer reaches the end of its lifespan, it needs to be replaced. However, replacement requires disassembling the upper rotating arm and a series of components mounted on it to replace the reducer. The reducer replacement process is complex, time-consuming, and labor-intensive, requiring the entire robot system to be shut down, thus impacting production schedules. Furthermore, the disassembly and assembly of heavy components poses a safety threat to operators. Utility Model Content

[0004] To address at least one of the technical problems existing in the background art, this application provides a display panel gripping robot that can simplify the reducer replacement process, reduce the replacement time and operational risks, improve maintenance efficiency and safety, and ensure the production schedule of display panels.

[0005] A second aspect of this application provides a display panel production line.

[0006] The technical solution adopted in this application is as follows:

[0007] The first aspect of this application provides a display panel grasping robot, comprising:

[0008] A base, wherein a reducer mounting groove is provided on the base, and a first blind hole and a second blind hole are formed on the outer edge of the reducer mounting groove;

[0009] A rotating arm is rotatably connected to the base, and an opening suitable for the speed reducer to pass through is formed on the rotating end of the rotating arm connected to the base;

[0010] The outer edge of the opening is formed with a first through hole and a second through hole, the first through hole corresponding to the first blind hole and the second through hole corresponding to the second blind hole;

[0011] When the reducer is disassembled and assembled, a first bolt is installed in the first blind hole and the first through hole, and a second bolt is installed in the second blind hole and the second through hole.

[0012] Guide surfaces are formed at the openings of the first through hole, the second through hole, the first blind hole, and the second blind hole;

[0013] Along the insertion direction of the first bolt, the diameter of the first through hole decreases, the diameter of the first blind hole decreases, and the maximum diameter of the first blind hole is not greater than the minimum diameter of the first through hole.

[0014] Along the insertion direction of the second bolt, the diameter of the second through hole decreases, the diameter of the second blind hole decreases, and the maximum diameter of the second blind hole is not greater than the minimum diameter of the second through hole;

[0015] In the absence of a reducer, the first bolt is adapted to maintain the gap between the base and the rotating end of the rotating arm, and the second bolt is adapted to maintain the connection between the base and the rotating end of the rotating arm. The first and second bolts are only used during the disassembly and installation of the reducer. After the reducer is installed, when the display panel gripping robot is operating normally, the first and second bolts do not need to be installed.

[0016] The first blind hole and the second blind hole are alternately distributed on the outer edge of the reducer mounting groove, and the first through hole and the second through hole are alternately distributed on the outer edge of the opening of the rotating arm.

[0017] According to the display panel grasping robot provided in the first aspect of this application, the reducer can be easily replaced by setting a reducer mounting slot on the base and forming a first blind hole and a second blind hole on its outer edge, and opening an opening at the rotating end of the rotating arm to accommodate the reducer. Specifically, the reducer mounting slot on the base is specifically for installing the reducer, and the rotating end of the rotating arm has an opening to accommodate the reducer, allowing the reducer to directly enter and exit through this opening. Therefore, during the replacement of the reducer, it is not necessary to disassemble the entire rotating arm or other parts of the robot, simplifying the disassembly process and significantly reducing the time required for reducing the reducer. When disassembling the reducer, the first bolt maintains an appropriate gap between the base and the rotating arm in the absence of the reducer, preventing friction or collision that may occur from direct contact between the two, while maintaining the relative position of the two components to facilitate the subsequent installation of the reducer; the second bolt ensures that the base and the rotating end of the rotating arm remain firmly connected when the reducer is not in place, preventing the components from loosening or shaking due to the lack of a reducer. The use of the first and second bolts simplifies the installation and disassembly process of the reducer, reduces the workload for maintenance personnel, and also reduces potential errors caused by complex operations. By ensuring a stable connection between the base and the rotating arm, the integrity of the structure is maintained even without the reducer, avoiding safety risks caused by loose or detached components. Furthermore, the guide surfaces formed at the openings of the first through hole, the second through hole, the first blind hole, and the second blind hole guide the bolts to enter the holes more easily, simplifying the bolt alignment process, reducing operation time, and lowering the risk of damage due to misoperation. As the bolt is inserted, the hole diameter gradually decreases, which not only helps the bolt to be more accurately aligned with the target position but also ensures that it moves along the correct axis, reducing unnecessary swaying or deviation and improving the installation speed and accuracy of the bolt. Once the first bolt is installed, it provides a tighter fit, ensuring that the first bolt can firmly maintain the gap between the base and the rotating arm, reducing the risk of loosening between the base and the rotating arm. Furthermore, the maximum diameter of the first blind hole is no greater than the minimum diameter of the first through hole. This design ensures a smooth transition for the first bolt as it passes through the first through hole and enters the first blind hole, preventing installation difficulties or bolt damage due to sudden changes in hole diameter. Similarly, along the insertion direction of the second bolt, the diameters of the second through hole and the second blind hole decrease, and the maximum diameter of the second blind hole is no greater than the minimum diameter of the second through hole, ensuring the stability and reliability of the second bolt installation. The alternating blind hole design makes the structural layout more rational, saving space and facilitating operation by maintenance personnel, thus improving the practicality and ergonomics of the design. In summary, the display panel gripping robot provided in this application embodiment can simplify the reducer replacement process, reduce replacement time and operational risks, improve maintenance efficiency and safety, and ensure the production progress of the display panel.

[0019] The hub cover has a central hole and a shaft hole, the central hole being suitable for the central shaft of the reducer to pass through;

[0047] like Figures 1 to 8As shown, a first aspect of this application provides a display panel grasping robot 1, including: a base 11, on which a reducer mounting groove 111 is provided, and a first blind hole 1111 and a second blind hole 1112 are formed on the outer edge of the reducer mounting groove 111; a rotating arm 12, rotatably connected to the base 11, and an opening 121 suitable for the reducer 15 to pass through is formed on the rotating end of the rotating arm 12 connected to the base 11; a first through hole 1211 and a second through hole 1212 are formed on the outer edge of the opening 121. 1 corresponds to the first blind hole 1111, and the second through hole 1212 corresponds to the second blind hole 1112; wherein, when the reducer 15 is disassembled or assembled, the first bolt 12111 is installed in the first blind hole 1111 and the first through hole 1211, and the second bolt 12121 is installed in the second blind hole 1112 and the second through hole 1212; guide surfaces 16 are formed at the openings of the first through hole 1211, the second through hole 1212, the first blind hole 1111, and the second blind hole 1112; along the insertion direction of the first bolt 12111, the diameter of the first through hole 1211 is... The diameter of the first blind hole 1111 decreases, and the maximum diameter of the first blind hole 1111 is not greater than the minimum diameter of the first through hole 1211; along the insertion direction of the second bolt 12121, the diameter of the second through hole 1212 decreases, the diameter of the second blind hole 1112 decreases, and the maximum diameter of the second blind hole 1112 is not greater than the minimum diameter of the second through hole 1212; in the state without the reducer 15, the first bolt 12111 is adapted to maintain the gap between the base 11 and the rotating end of the rotating arm 12, and the second bolt 12121 is adapted to make the base 11 and the rotating arm 12... The rotating ends of the arms 12 remain connected; the first bolt 12111 and the second bolt 12121 are only used during the disassembly and installation of the reducer 15. After the reducer 15 is installed, the first bolt 12111 and the second bolt 12121 do not need to be installed when the display panel gripping robot 1 is in normal working condition; the first blind hole 1111 and the second blind hole 1112 are alternately distributed on the outer edge of the reducer mounting groove 111, and the first through hole 1211 and the second through hole 1212 are alternately distributed on the outer edge of the opening 121 of the rotating arm 12.

[0048] The base 11 has a dedicated reducer mounting slot 111. The edge of the reducer mounting slot 111 forms a first blind hole 1111 and a second blind hole 1112. These two blind holes are for matching with the subsequent first bolt 12111 and second bolt 12121, respectively. The connection between the rotating arm 12 and the base 11 forms an opening 121 suitable for the reducer 15 to pass through. The reducer 15 can be directly installed or removed from this opening 121 without disassembling the entire robot structure. During the disassembly and assembly of the reducer 15, the first bolt 12111 installed in the first blind hole 1111 and the first through hole 1211, and the second bolt 12121 installed in the second blind hole 1112 and the second through hole 1212, play a crucial role. Specifically, the first bolt 12111 maintains an appropriate gap between the base 11 and the rotating arm 12 when the reducer 15 is not present, ensuring that they do not experience unnecessary friction or wear due to contact. The second bolt 12121 maintains the connection between the base 11 and the rotating arm 12 even when the reducer 15 is missing, preventing the rotating arm 12 from wobbling or shifting due to loss of support, thus ensuring the robot's structural stability. Even without the reducer 15, the robot maintains good structural stability and rigidity, ensuring the safety of maintenance personnel when replacing the reducer 15.

[0049] According to the first aspect of the present application, the display panel grasping robot 1 achieves convenient replacement of the reducer 15 by providing a reducer mounting groove 111 on the base 11 and forming a first blind hole 1111 and a second blind hole 1112 on its outer edge, and by opening an opening 121 at the rotating end of the rotating arm 12 to accommodate the reducer 15. Specifically, the reducer mounting groove 111 on the base 11 is specifically used to install the reducer 15, and the rotating end of the rotating arm 12 has an opening 121 to accommodate the reducer 15. The reducer 15 can directly enter and exit through this opening 121. Therefore, during the replacement of the reducer 15, it is not necessary to disassemble the entire rotating arm 12 and other parts of the robot. The disassembly process is simple, significantly reducing the time required to replace the reducer 15. When disassembling the reducer 15, the first bolt 12111 maintains an appropriate gap between the base 11 and the rotating arm 12 when the reducer 15 is not in place, preventing friction or collision that may occur from direct contact between the two, while maintaining the relative position of the two components to facilitate the subsequent installation of the reducer 15. The second bolt 12121 ensures that the rotating end of the base 11 and the rotating arm 12 remains firmly connected when the reducer 15 is not in place, preventing the components from loosening or shaking due to the absence of the reducer 15. The use of the first bolt 12111 and the second bolt 12121 simplifies the installation and disassembly process of the reducer 15, reduces the difficulty of maintenance personnel's work, and also reduces potential errors caused by complex operation. By ensuring a stable connection between the base 11 and the rotating arm 12, the integrity of the structure can be maintained even when the reducer 15 is not in place, avoiding safety risks caused by loosening or falling off of components. Furthermore, the guide surfaces 16 formed at the openings of the first through hole 1211, the second through hole 1212, the first blind hole 1111, and the second blind hole 1112 can guide the bolt to enter the hole more easily, simplifying the bolt alignment process, reducing operation time, and lowering the risk of damage due to misoperation. As the bolt is inserted, the hole diameter gradually decreases, which not only helps the bolt to be more accurately aligned with the target position but also ensures that it moves along the correct axis, reducing unnecessary swaying or offset and improving the installation speed and accuracy of the bolt. Once the first bolt 12111 is installed in place, it provides a tighter fit, ensuring that the first bolt 12111 can firmly maintain the gap between the base and the rotating arm, reducing the risk of loosening between the base 11 and the rotating arm 12. Furthermore, the maximum diameter of the first blind hole 1111 is not greater than the minimum diameter of the first through hole 1211. This design ensures that the first bolt 12111 can smoothly transition when passing through the first through hole 1211 and entering the first blind hole 1111, without causing installation difficulties or bolt damage due to sudden changes in the hole diameter.Similarly, along the insertion direction of the second bolt 12121, the diameters of the second through hole 1212 and the second blind hole 1112 also decrease, and the maximum diameter of the second blind hole 1112 is not greater than the minimum diameter of the second through hole 1212, which also ensures the stability and reliability of the installation of the second bolt 12121. In summary, the display panel gripping robot 1 provided in this application embodiment can simplify the replacement process of the reducer 15, reduce the time required for replacement and the operational risks, improve maintenance efficiency and safety, and ensure the production progress of the display panel 2.

[0050] In addition, such as Figure 5 As shown, the first blind hole 1111 and the second blind hole 1112 are alternately distributed on the outer edge of the reducer mounting groove 111. Correspondingly, the first through hole 1211 and the second through hole 1212 are also alternately distributed on the outer edge of the opening 121 of the rotating arm 12. The alternating blind hole design makes the structural layout more reasonable, not only saving space but also facilitating operation by maintenance personnel, thus improving the practicality and ergonomics of the design. The first blind hole 1111 and the second blind hole 1112, which are alternately distributed on the outer edge of the reducer mounting groove 111, enable quick replacement of the reducer 15 by cooperating with the first bolt 12111 and the second bolt 12121, while ensuring the structural stability and safety of the robot.

[0051] like Figures 1 to 3 As shown, in some embodiments of this application, a hub cover 122 is installed on the rotating arm 12, covering the opening 121. The hub cover 122 has a central hole 1221 and a shaft hole 1222, with the central hole 1221 suitable for the central shaft of the reducer 15 to pass through. The display panel gripping robot 1 also includes a rotary drive motor, the rotating shaft of which passes through the shaft hole 1222 to connect to the reducer 15. The hub cover 122 covering the opening 121 effectively prevents external dust and impurities from entering the reducer 15, avoiding contamination of the precision transmission mechanism of the reducer 15. The hub cover 122 isolates the reducer 15 and the rotating drive motor's operating components to a certain extent, reducing the risk of accidental contact with high-speed rotating components by operators and improving operational safety. The central hole 1221 and shaft hole 1222 on the hub cover facilitate the passage of the central shaft of the reducer 15 and the motor shaft, ensuring a stable connection between the reducer 15 and the rotary drive motor. When it is necessary to replace the reducer 15 or perform maintenance, the reducer 15 can be disassembled by removing the hub cover 122, which simplifies the maintenance process and improves the efficiency of maintenance work.

[0052] like Figure 3As shown, in some embodiments of this application, the outer edge of the hub cover 122 is connected to the outer edge of the opening 121 of the rotating arm 12; the hub cover 122 also has a recessed portion 1223, which is connected to the reducer 15. The outer edge of the hub cover 122 is tightly connected to the outer edge of the opening 121 of the rotating arm 12, forming a barrier that effectively prevents external dust and foreign objects from entering the reducer 15, ensuring the cleanliness and normal operation of the reducer 15. In addition, it also provides a certain sound insulation effect, reducing the noise of the reducer 15 during operation. The recessed portion 1223 on the hub cover 122 is directly connected to the reducer 15, which not only enhances the installation stability of the hub cover 122 but also ensures the quick positioning and fixing of the reducer 15 during replacement or maintenance. The design of the recessed portion 1223 cleverly utilizes space, allowing the hub cover 122 to fit tightly against the reducer 15, reducing the overall volume and improving space utilization. When disassembling the old reducer 15, only the hub cover 122 needs to be removed first, and then the reducer 15 can be taken out, without having to disassemble the entire robot extensively, which greatly saves maintenance time and labor costs. Similarly, when installing the new reducer 15, the reducer 15 can be quickly positioned and fixed by matching the sinker 1223 with the reducer 15, avoiding installation difficulties caused by inaccurate positioning.

[0053] like Figure 3 As shown, in some embodiments of this application, the outer edge of the hub cover 122 has a notch to avoid the first through hole 1211 and the second through hole 1212, so that the first through hole 1211 and the second through hole 1212 are exposed. The notch designed on the outer edge of the hub cover 122 is specifically reserved for the first through hole 1211 and the second through hole 1212. This allows direct contact with the through holes without disassembling the hub cover 122, thereby enabling the installation or removal of the first bolt 12111 and the second bolt 12121. When replacing the reducer 15, it is not necessary to first remove the hub cover 122; the bolts can be directly screwed in through the notch, simplifying the replacement process and saving a lot of time. Frequent disassembly and assembly of the hub cover 122 is avoided, reducing maintenance workload, improving work efficiency, and also reducing the risk of component damage caused by repeated disassembly and assembly. Even without the reducer 15, the first bolt 12111 and the second bolt 12121 can still maintain the appropriate gap and connection between the base 11 and the rotating arm 12, ensuring the stability of the robot structure. Even when the reducer 15 is replaced, the overall structural safety of the robot is not affected.

[0054] like Figure 8As shown, in some embodiments of this application, the display panel gripping robot 1 further includes a lifting arm 13 and a mechanical gripper 14; the lifting arm 13 is connected to the swing end of the rotating arm 12, and the mechanical gripper 14 is connected to the lifting end of the lifting arm 13; the rotating arm 12 is adapted to drive the lifting arm 13 to move horizontally, and the lifting arm 13 is adapted to drive the mechanical gripper 14 to move vertically. The rotating arm 12 provides horizontal movement capability, enabling the lifting arm 13 and the mechanical gripper 14 to perform a wide range of position adjustments on the horizontal plane to meet the material gripping needs at different positions. The lifting arm 13 is connected to the swing end of the rotating arm 12 and can move horizontally with the rotating arm 12 under its drive, while also possessing vertical movement capability. Through lifting and lowering actions, the mechanical gripper 14 can grip and release materials at different heights. The mechanical gripper 14 is installed at the lifting end of the lifting arm 13 and is directly responsible for gripping and releasing materials. The design of the mechanical gripper 14 can be determined based on the size and weight of the display panel 2, ensuring that the display panel 2 will not be damaged during transportation, while also ensuring sufficient gripping force to prevent the display panel 2 from falling.

[0055] like Figure 8 As shown, in some embodiments of this application, a track groove 112 is also provided on the base 11, and the rotating arm 12 is slidably connected to the track groove 112; the extension direction of the track groove 112 is horizontal. The sliding connection design of the track groove 112 and the rotating arm 12 on the base 11 provides basic structural support for the horizontal movement of the mechanical gripper 14. The horizontal extension direction of the track groove 112 allows the rotating arm 12 to move smoothly laterally along the horizontal axis, thereby driving the entire mechanical gripper 14 to perform horizontal positioning and movement on the production line. Guided by the track groove 112, the movement path of the rotating arm 12 is more precise and controllable, which helps to improve the positioning accuracy of the mechanical gripper 14 when gripping the display panel 2, ensuring the accuracy of each gripping and placement operation. The horizontal track groove 112 allows the mechanical gripper 14 to move easily between different workstations on the production line, improving the application flexibility of the robot on the production line and adapting to the needs of various production tasks.

[0056] This application also provides a robot maintenance method for the display panel gripping robot 1 based on any of the embodiments of the first aspect described above, including:

[0057] Step 100: Install the first bolt 12111 into the first through hole 1211, wherein the first bolt 12111 extends into the first blind hole 1111.

[0058] Step 200: Install the second bolt 12121 into the second through hole 1212, wherein the second bolt 12121 extends into the second blind hole 1112.

[0059] Step 300: Disassemble the old reducer 15 and remove it from the opening 121 at the rotating end of the rotating arm 12.

[0060] Step 400: Insert the new reducer 15 into the reducer mounting slot 111 through the opening 121 for installation.

[0061] Step 500: After installation, remove the first bolt 12111 and the second bolt 12121.

[0062] In step 100, firstly, the first bolt 12111 is inserted into the first through hole 1211 and extends into the first blind hole 1111. The purpose of this step is to maintain the gap between the base 11 and the rotating arm 12 by the first bolt 12111 before disassembling the reducer 15, ensuring that the two will not come into direct contact during the replacement of the reducer 15, thus avoiding possible friction or damage.

[0063] In step 200, the second bolt 12121 is then inserted into the second through hole 1212, extending it into the second blind hole 1112. The function of the second bolt 12121 is to maintain a stable connection between the base 11 and the rotating end of the rotating arm 12 before disassembling the reducer 15, preventing structural instability caused by the lack of the reducer 15.

[0064] In step 300, with the assistance of the first bolt 12111 and the second bolt 12121, the old reducer 15 can be safely disassembled. The old reducer 15 can be removed from the rotating end opening 121 of the rotating arm 12. Due to the presence of the first bolt 12111 and the second bolt 12121, this process can be carried out smoothly without worrying about structural issues between the base 11 and the rotating arm 12.

[0065] In step 400, the new reducer 15 is inserted into the reducer mounting slot 111 through the opening 121 for installation. At this time, due to the presence of the first bolt 12111 and the second bolt 12121, the installation of the new reducer 15 can be more precise and stable, saving time and effort, and ensuring a good connection with the base 11 and the rotating arm 12.

[0066] In step 500, after the new reducer 15 is installed, the first bolt 12111 and the second bolt 12121 are removed, restoring the robot to its original state. This step signifies that the reducer 15 has been successfully replaced, and the tasks of the first bolt 12111 and the second bolt 12121 are complete.

[0067] According to the robot maintenance method provided in this application embodiment, by using the first bolt 12111 and the second bolt 12121 as temporary fasteners, the replacement process of the reducer 15 is simplified, the replacement time is reduced, the operational difficulty and risk for maintenance personnel are lowered, and the maintenance efficiency and reliability of the display panel gripping robot 1 are improved. Furthermore, the old reducer 15 can exit from the rotating end opening 121 of the rotating arm 12, avoiding excessive disassembly of the robot, helping to protect other parts of the robot from damage, and extending the robot's service life.

[0068] In some embodiments of this application, the method further includes:

[0069] Before removing the old reducer 15, remove the hub cover 122 installed on the rotating arm 12;

[0070] After installing the new reducer 15, reinstall the wheel hub cover 122.

[0071] During the replacement of the reducer 15 of the display panel gripping robot 1, in addition to the basic steps of disassembling the old reducer 15 and installing the new reducer 15, the process also includes the disassembly and reassembly of the hub cover 122. Before disassembling the old reducer 15, the hub cover 122 installed on the rotating arm 12 must be removed first. This operation is mainly to ensure unobstructed access during the replacement of the reducer 15, making it easier for operators to approach the installation area of ​​the reducer 15 and improving replacement efficiency. Removing the hub cover 122 also avoids accidental damage to it during the replacement of the reducer 15, ensuring the integrity of the hub cover 122. After the new reducer 15 is installed, it is essential to reinstall the hub cover 122. The hub cover 122 not only serves an aesthetic purpose, but more importantly, it protects the reducer 15 from the influence of the external environment, such as preventing dust and debris from entering the reducer 15, ensuring the normal operation of the reducer 15 and extending its service life. At the same time, the hub cover 122 can also play a certain safety protection role, preventing operators from accidentally coming into contact with the high-speed rotating reducer 15 when the robot is running, thus reducing the occurrence of safety accidents.

[0072] A second aspect of this application provides a display panel production line, including the display panel gripping robot 1 described in any of the first aspects above.

[0073] According to the display panel production line provided in the second aspect embodiment of this application, the display panel 2 can be automatically transported and processed. The quick replacement mechanism of the reducer 15 of the display panel gripping robot 1 reduces the downtime of the production line, lowers maintenance costs, and improves the reliability and stability of the production line, significantly improving production efficiency and reducing maintenance time.
