Description

Technical Field

[0001] The present application belongs to the technical field of display panel production equipment, and specifically relates to a display panel grasping robot, a robot maintenance method and a display panel production line. Background Art

[0002] With the increasing demand for high-definition displays and the growth of portable terminal consumption, traditional CRT displays are gradually being replaced by thin and light flat-panel displays. This has promoted the research and commercialization of thin-film flat-panel displays. In the manufacturing process of flat-panel displays, including deposition, photolithography, and etching, automated equipment is required to handle display panels. Among them, display panel grabbing robots play a key role in this process. They are used to transport display panels to specific processing stations to complete production.

[0003] The existing display panel grabbing robot mainly includes a base, a rotating arm arranged on the base, and a mechanical gripper arranged on the rotating arm. The rotating arm rotates to drive the mechanical gripper to grab the display panels on different workstations to realize the transportation of the display panels. A reducer is arranged between the rotating arm and the base. The life of the reducer is limited, about five years. When the reducer reaches the end of its service life, it needs to be replaced. However, when replacing it, it is necessary to disassemble the upper rotating arm and a series of components arranged on the rotating arm before the reducer can be replaced. The replacement process of the reducer is complicated, time-consuming and labor-intensive, and requires the shutdown of the entire robot system, affecting the production schedule. In addition, the disassembly and assembly of heavy components poses a threat to the safety of operators. Summary of the invention

[0004] In order to solve at least one technical problem existing in the background technology, the present application provides a display panel grasping robot, which can simplify the replacement process of the reducer, reduce the time and operational risks required for replacement, improve maintenance efficiency and safety, and ensure the production progress of the display panel.

[0005] A second aspect of the present application provides a robot maintenance method.

[0006] A third aspect of the present application provides a display panel production line.

[0007] The technical solution adopted in this application is:

[0008] A first aspect of the present application provides a display panel grasping robot, comprising:

[0009] A base, wherein a reducer mounting groove is provided on the base, and a first blind hole and a second blind hole are formed at an outer edge of the reducer mounting groove;

[0010] A rotating arm, the rotating arm is rotatably connected to the base, and an opening suitable for the reducer to pass through is formed on the rotating end of the rotating arm connected to the base;

[0011] A first through hole and a second through hole are formed at the outer edge of the opening, wherein the first through hole corresponds to the first blind hole, and the second through hole corresponds to the second blind hole;

[0012] Wherein, 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;

[0013] In a state without a speed reducer, the first bolt is suitable for maintaining a gap between the base and the rotating end of the rotating arm, and the second bolt is suitable for maintaining a connection state between the base and the rotating end of the rotating arm.

[0014] According to the display panel grabbing robot provided by the embodiment of the first aspect of the present application, the reducer is conveniently replaced by arranging a reducer installation groove on the base and forming a first blind hole and a second blind hole on its outer edge, and opening an opening adapted to the passage of the reducer is opened at the rotating end of the rotating arm. Specifically, the reducer installation groove on the base is specifically used to install the reducer, and the rotating end of the rotating arm is provided with an opening adapted to the passage of the reducer, and the reducer can directly enter and exit from this opening. Therefore, in the process of replacing the reducer, it is not necessary to disassemble the entire rotating arm and disassemble other parts of the robot. The disassembly process is simple, which significantly reduces the man-hours required to replace the reducer. When disassembling the reducer, the function of the first bolt is to maintain an appropriate gap between the base and the rotating arm in the state without the reducer, to avoid friction or collision that may be caused by direct contact between the two, and to maintain the relative position of the two components, so as to facilitate the subsequent installation of the reducer; the second bolt ensures that the base and the rotating end of the rotating arm are still firmly connected when the reducer is not in place, to prevent the components from loosening or shaking due to the lack of the reducer. The use of the first bolt and the second bolt simplifies the installation and disassembly process of the reducer, reduces the difficulty of the 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 can be maintained even in the absence of a reducer, avoiding safety risks caused by loose or falling parts. In summary, the display panel grasping robot provided in the embodiment of the present application can simplify the replacement process of the reducer, reduce the time required for replacement and the operational risks, improve maintenance efficiency and safety, and ensure the production progress of the display panel.

[0055] like Figures 1 to 8 As shown, the first embodiment of the present application provides a display panel grasping robot 1, comprising: a base 11, a reducer mounting groove 111 is provided on the base 11, and a first blind hole 1111 and a second blind hole 1112 are formed at the outer edge of the reducer mounting groove 111; a rotating arm 12, the rotating arm 12 is 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 at the outer edge of the opening 121, and the first through hole 1211 Corresponding to the first blind hole 1111, the second through hole 1212 corresponds to the second blind hole 1112; wherein, when the reducer 15 is disassembled and assembled, the first blind hole 1111 and the first through hole 1211 are installed with the first bolt 12111, and the second blind hole 1112 and the second through hole 1212 are installed with the second bolt 12121; in the state without the reducer 15, the first bolt 12111 is suitable for maintaining the gap between the base 11 and the rotating end of the rotating arm 12, and the second bolt 12121 is suitable for keeping the base 11 and the rotating end of the rotating arm 12 in a connected state.

[0056] The base 11 is provided with a special reducer installation groove 111, and the edge of the reducer installation groove 111 forms a first blind hole 1111 and a second blind hole 1112, which are respectively matched with the subsequent first bolt 12111 and the second bolt 12121. An opening 121 suitable for the reducer 15 to pass through is formed at the connection between the rotating arm 12 and the base 11, and the reducer 15 can be directly installed or removed from this opening 121 without disassembling the entire robot structure. During the disassembly and assembly process 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 key role, that is, the first bolt 12111 is used to maintain the appropriate gap between the base 11 and the rotating arm 12 in the absence of the reducer 15, ensuring that the two will not produce unnecessary friction or wear due to contact; the second bolt 12121 is responsible for maintaining the connection between the base 11 and the rotating arm 12 in the absence of the reducer 15, preventing the rotating arm 12 from shaking or deflecting due to loss of support, and ensuring the structural stability of the robot. Even in the absence of the reducer 15, the robot can maintain good structural stability and rigidity, and the safety of maintenance personnel when replacing the reducer 15 is guaranteed.

[0057] It should be noted that, in the embodiment of the present application, the first bolt 12111 and the second bolt 12121 are only used during the disassembly and installation process of the reducer 15. After the reducer 15 is installed and the display panel grasping robot 1 is in normal working condition, the first bolt 12111 and the second bolt 12121 do not need to be installed.

[0058] According to the display panel grasping robot 1 provided by the embodiment of the first aspect of the present application, by setting a reducer installation groove 111 on the base 11 and forming a first blind hole 1111 and a second blind hole 1112 on its outer edge, and opening 121 adapted to the passage of the reducer 15 is opened at the rotating end of the rotating arm 12, convenient replacement of the reducer 15 is achieved. Specifically, the reducer installation groove 111 on the base 11 is specifically used to install the reducer 15, and the rotating end of the rotating arm 12 is provided with an opening 121 adapted to the passage of the reducer 15, and the reducer 15 can directly enter and exit from this opening 121. Therefore, in the process of replacing the reducer 15, there is no need to disassemble the entire rotating arm 12 and disassemble other parts of the robot. The disassembly process is simple, which significantly reduces the man-hours required for replacing the reducer 15. When the reducer 15 is disassembled, the function of the first bolt 12111 is to maintain an appropriate gap between the base 11 and the rotating arm 12 in the state without the reducer 15, to avoid friction or collision that may be caused by direct contact between the two, and to maintain the relative position of the two components, so as to facilitate the subsequent installation of the reducer 15; the second bolt 12121 ensures that the base 11 and the rotating end of the rotating arm 12 are still firmly connected when the reducer 15 is not in place, so as to prevent the components from loosening or shaking due to the lack 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 the maintenance personnel, and also reduces the potential errors caused by complex operations. By ensuring the stable connection between the base 11 and the rotating arm 12, the integrity of the structure can be maintained even in the state without the reducer 15, avoiding the safety risks caused by loose or falling components. In summary, the display panel grasping robot 1 provided in the embodiment of the present application can simplify the replacement process of the reducer 15, reduce the time and operation risk required for replacement, improve maintenance efficiency and safety, and ensure the production progress of the display panel 2.

[0059] like Figures 1 to 3As shown, in some embodiments of the present application, a hub cover 122 is installed on the rotating arm 12, and the hub cover 122 covers the opening 121; a central hole 1221 and an axial hole 1222 are formed on the hub cover 122, and the central hole 1221 is suitable for the central axis of the reducer 15 to pass through; the display panel grasping robot 1 also includes a rotating drive motor, and the rotating shaft of the rotating drive motor is passed through the axial hole 1222 to connect to the reducer 15. The hub cover 122 covers the opening 121, which can effectively prevent external dust and impurities from entering the reducer 15, and avoid contaminating the precision transmission mechanism of the reducer 15. The setting of the hub cover 122 isolates the running parts of the reducer 15 and the rotating drive motor to a certain extent, reduces the risk of accidental contact of the operator with the high-speed rotating parts, and improves the safety of operation. The hub cover 122 is designed with a central hole 1221 and an axial hole 1222, which is convenient for the passing of the central axis of the reducer 15 and the motor shaft, and ensures the stable connection between the reducer 15 and the rotating drive motor. When the reducer 15 needs to be replaced or maintained, the reducer 15 can be disassembled by removing the hub cover 122, which simplifies the maintenance process and improves the maintenance work efficiency.

[0060] like Figure 3 As shown, in some embodiments of the present 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 is also formed with a sinking portion 1223, and the sinking portion 1223 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, effectively preventing external dust and foreign matter from entering the reducer 15, ensuring the cleanliness and normal operation of the reducer 15. In addition, it also has a certain sound insulation effect, reducing the noise when the reducer 15 is running. The sinking 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 rapid positioning and fixing of the reducer 15 during replacement or maintenance. The design of the sinking portion 1223 cleverly utilizes the space, so that the hub cover 122 can be close to the reducer 15, reducing the overall volume and improving the space utilization. When removing the old reducer 15, it is only necessary to remove the hub cover 122 first, and then take out the reducer 15, without having to disassemble the entire robot to a large extent, which greatly saves maintenance time and labor costs. Similarly, when installing a new reducer 15, the reducer 15 can be quickly positioned and fixed by matching the sinking part 1223 with the reducer 15, avoiding installation difficulties caused by inaccurate positioning.

[0061] like Figure 3As shown, in some embodiments of the present application, the outer edge of the hub cover 122 is formed with 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 avoidance notch designed on the outer edge of the hub cover 122 is reserved specifically for the first through hole 1211 and the second through hole 1212, so that the through holes can be directly contacted without disassembling the hub cover 122, and then the first bolt 12111 and the second bolt 12121 can be installed or removed. When replacing the reducer 15, there is no need to disassemble the hub cover 122 first, and the bolts can be directly screwed in through the notch, which simplifies the replacement process and greatly saves time. It avoids frequent disassembly and assembly of the hub cover 122, reduces maintenance workload, improves work efficiency, and also reduces the risk of component damage caused by multiple 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 state between the base 11 and the rotating arm 12, ensuring the stability of the robot structure. Even during the replacement of the reducer 15, the overall structural safety of the robot is not affected.

[0062] like Figure 5 As shown, in some embodiments of the present application, the first blind hole 1111 and the second blind hole 1112 are alternately distributed on the outer edge of the reducer mounting slot 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 design of the alternating blind holes makes the structural layout more reasonable, which not only saves space, but also facilitates the operation of maintenance personnel, thereby 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 slot 111, are used in conjunction with the first bolt 12111 and the second bolt 12121 to achieve rapid replacement of the reducer 15, while ensuring the structural stability and safety of the robot.

[0063] like Figure 8As shown, in some embodiments of the present application, the display panel grabbing robot 1 also 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 suitable for driving the lifting arm 13 to move horizontally, and the lifting arm 13 is suitable for driving the mechanical gripper 14 to move in the vertical direction. The rotating arm 12 provides the ability to move in the horizontal direction, and can drive the lifting arm 13 and the mechanical gripper 14 to adjust their positions in a wide range on the horizontal plane to meet the material grabbing requirements 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 the drive of the rotating arm 12. At the same time, it has the ability to move in the vertical direction. Through the lifting action, the mechanical gripper 14 can realize the grabbing and releasing of materials at different heights. The mechanical gripper 14 is installed at the lifting end of the lifting arm 13, and is directly responsible for the grabbing and releasing of materials. The design of the mechanical gripper 14 can be determined based on the size and weight of the display panel 2 to ensure that the display panel 2 is not damaged during transportation and that sufficient gripping force is guaranteed to prevent the display panel 2 from falling.

[0064] like Figure 8 As shown, in some embodiments of the present application, a track groove 112 is further 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 provided on the base 11 provides basic structural support for the horizontal movement of the mechanical gripper 14. The extension direction of the track groove 112 is horizontal, which enables the rotating arm 12 to move smoothly laterally along the horizontal axis, thereby driving the entire mechanical gripper 14 to position and move horizontally 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 grabbing the display panel 2, and ensure the accuracy of each grabbing and placing operation. The horizontal track groove 112 allows the mechanical gripper 14 to easily move between different workstations on the production line, improves the application flexibility of the robot on the production line, and adapts to the needs of various production tasks.

[0065] like Fig. 9 As shown, the second aspect of the present application provides a robot maintenance method based on the display panel grasping robot 1 in any embodiment of the first aspect, including:

[0066] Step 100 : Install a first bolt 12111 into the first through hole 1211 , wherein the first bolt 12111 penetrates into the first blind hole 1111 .

[0067] Step 200 , installing a second bolt 12121 into the second through hole 1212 , wherein the second bolt 12121 penetrates into the second blind hole 1112 .

[0068] Step 300 , dismantle the old reducer 15 , and take the old reducer 15 out of the opening 121 at the rotating end of the rotating arm 12 .

[0069] Step 400: Place the new reducer 15 through the opening 121 into the reducer installation slot 111 for installation.

[0070] Step 500 , after installation is completed, remove the first bolt 12111 and the second bolt 12121 .

[0071] In step 100, first, the first bolt 12111 is inserted into the first through hole 1211 and penetrates 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, so as to ensure that the two will not directly contact during the replacement of the reducer 15, thereby avoiding possible friction or damage.

[0072] In step 200, the second bolt 12121 is then inserted into the second through hole 1212, so that it penetrates into the second blind hole 1112. The second bolt 12121 is used to maintain a stable connection between the base 11 and the rotating end of the rotating arm 12 before the reducer 15 is disassembled, so as to prevent structural instability caused by the lack of the reducer 15.

[0073] 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 taken out 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 the structural problems between the base 11 and the rotating arm 12.

[0074] In step 400, the new reducer 15 is placed into the reducer installation groove 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 accurate and stable, saving time and effort, and ensuring a good connection with the base 11 and the rotating arm 12.

[0075] In step 500, after the new reducer 15 is installed, the first bolt 12111 and the second bolt 12121 are removed to restore the original state of the robot. This step means that the reducer 15 has been successfully replaced, and the tasks of the first bolt 12111 and the second bolt 12121 are completed.

[0076] According to the robot maintenance method provided by the second embodiment of the present application, by using the first bolt 12111 and the second bolt 12121 as temporary fixings, the replacement process of the reducer 15 is simplified, the replacement time is reduced, the operation difficulty and risk of the maintenance personnel are reduced, and the maintenance efficiency and reliability of the display panel grasping robot 1 are improved. In addition, the old reducer 15 can be taken out from the opening 121 at the rotating end of the rotating arm 12, avoiding excessive disassembly of the robot, helping to protect other parts of the robot from damage, and extending the service life of the robot.

[0077] In some embodiments of the present application, the method further comprises:

[0078] Before disassembling the old reducer 15, remove the hub cover 122 mounted on the rotating arm 12;

[0079] After the new reducer 15 is installed, the hub cover 122 is reinstalled.

[0080] In the process of replacing the reducer 15 of the display panel grasping robot 1, in addition to the basic steps of disassembling the old reducer 15 and installing the new reducer 15, the process of disassembling and assembling the hub cover 122 is also included. Before disassembling the old reducer 15, the hub cover 122 installed on the rotating arm 12 needs to be disassembled first. This operation is mainly to ensure that there is no obstacle when replacing the reducer 15, to facilitate the operator to approach the installation area of ​​the reducer 15, and to improve the replacement efficiency. The removal of the hub cover 122 also avoids accidental damage to the reducer 15 when replacing it, and ensures that the hub cover 122 is intact. After the new reducer 15 is installed, it is very necessary to reinstall the hub cover 122.
