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 from different workstations, thus transferring the display panels. A reducer is installed between the rotating arm and the base. The reducer has a limited lifespan of approximately five years. When the reducer reaches the end of its service life, it needs to be replaced. To simplify the reducer replacement process and reduce the time and operational risks, an opening is formed on the rotating end where the rotating arm connects to the base, allowing the reducer to pass through directly for installation and removal.

[0004] Based on the above structure, a problem arises where the protective performance of the reducer decreases. For example, impurities such as dust, water stains, or oil stains can enter the reducer through this opening, affecting its operational stability. In addition, the reducer generates heat during operation. Therefore, how to ensure both the protective performance and heat dissipation effect of the reducer is a technical problem that urgently needs to be solved. Utility Model Content

[0005] In order to solve at least one of the technical problems existing in the background art, this application provides a display panel grasping robot, which can ensure the protection performance and heat dissipation effect of the reducer based on the structure of easy disassembly and assembly of the reducer.

[0006] A second aspect of this application provides a display panel production line.

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

[0008] The first aspect of this application provides a display panel grasping robot, comprising:

[0009] A base, wherein the base is provided with a receiving groove suitable for installing a speed reducer;

[0010] 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;

[0011] A bearing is provided between the base and the rotating end of the rotating arm;

[0012] A hub cover is mounted on the rotating arm, and the hub cover is disposed over the opening;

[0013] 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;

[0014] The display panel grasping robot also includes a rotary drive motor, the rotary drive motor's rotating shaft passing through the shaft hole to connect to the reducer;

[0015] The hub cover has a support portion on the side facing the reducer, and the support portion is connected to the outer periphery of the reducer;

[0016] The support portion has heat dissipation holes on its side wall.

[0017] According to the first aspect of the embodiment of the display panel grasping robot provided in this application, the receiving slot on the base is specifically designed for installing the reducer, and the rotating end of the rotating arm has an opening adapted to the reducer. The reducer can 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. The disassembly process is simple, significantly reducing the time required for reducing the reducer replacement. The bearing provided between the base and the rotating end of the rotating arm helps support the weight and movement of the rotating arm, while reducing the burden on the reducer. The use of the bearing makes the overall rotation of the rotating arm more stable, improving the operating efficiency and accuracy of the display panel grasping robot. By providing an opening on the rotating arm, combined with the bearing design, the replacement of the reducer becomes simple and quick. The operator can directly remove the reducer through the opening, and the entire process will not affect the bearing or other components, avoiding frequent disassembly and assembly of heavy components and reducing potential hazards in maintenance operations. The hub cover can protect the reducer from the influence of the external environment. The hub cover is installed on the rotating arm and precisely covers the opening of the reducer. In this way, the cleanliness and safety of the reducer can be ensured, preventing dust and impurities from entering the reducer and affecting its normal operation. When replacing the reducer, first open the hub cover to expose the opening, then remove the reducer. The bottom of the support unit can abut against the reducer, which provides additional physical support for the hub cover, reducing defects such as hub cover displacement and abnormal noise caused by vibration or load, enhancing the overall structural robustness, and ensuring reliable protection of the reducer by the hub cover. By opening heat dissipation holes on the side wall of the support unit, the heat generated during reducer operation can be directly dissipated, preventing heat accumulation and overheating. Appropriate heat dissipation measures help maintain the reducer within an ideal temperature range, reducing problems such as material aging and lubrication failure caused by overheating, and extending its service life. The opening design on the side wall reduces the risk of dust and other particles falling directly into the reducer; dust falling from above is unlikely to enter the interior directly through the side openings.

[0018] Furthermore, the combined use of bearings and reducers allows the bearings to bear a portion of the load, reducing the pressure on the reducer and enabling it to operate under optimal conditions. This reduces wear and failure rates, enhancing not only the load-bearing capacity and rotational stability of the display panel gripping robot but also extending the reducer's service life. In summary, the display panel gripping robot provided in this application embodiment can ensure the reducer's protective performance and heat dissipation effect based on its easily detachable reducer structure.

[0020] According to one embodiment of this application, a dust filter is provided in the heat dissipation hole.

[0021] According to one embodiment of this application, the maximum outer dimension of the support portion is smaller than the inner diameter of the bearing.

[0022] According to one embodiment of this application, the bearing includes an inner ring and an outer ring, the inner ring being connected to the base and the outer ring being connected to the rotating arm;

[0023] A ball roller is provided between the outer ring and the inner ring.

[0024] According to one embodiment of this application, the bearing is sleeved on the outer periphery of the receiving groove.

[0025] According to one embodiment of this application, the display panel grasping robot further includes a lifting arm and a mechanical gripper;

[0026] The lifting arm is connected to the swing end of the rotating arm, and the mechanical gripper is connected to the lifting end of the lifting arm;

[0027] The rotating arm is adapted to drive the lifting arm to move horizontally, and the lifting arm is adapted to drive the mechanical gripper to move vertically.

[0028] According to one embodiment of this application, the base is further provided with a track groove, and the rotating arm is slidably connected to the track groove;

[0029] The track groove extends in a horizontal direction.

[0030] According to one embodiment of this application, the mechanical gripper includes at least two telescopic arms and a display panel fork;

[0031] The two adjacent telescopic arms are rotatably connected, and the display panel fork is located at the end of the last telescopic arm.

[0032] A second aspect of this application provides a display panel production line, including the display panel gripping robot described in any of the embodiments of the first aspect above. Attached Figure Description

[0048] like Figures 1 to 7 As shown, a first aspect of this application provides a display panel gripping robot 1, comprising: a base 11, on which a receiving groove 111 suitable for mounting a reducer 17 is provided; a rotating arm 12, rotatably connected to the base 11, with an opening 121 formed on the rotating end of the rotating arm 12 connected to the base 11, suitable for the reducer 17 to pass through; a bearing 13 provided between the base 11 and the rotating end of the rotating arm 12; and a hub cover 122 mounted on the rotating arm 12, the hub cover 122 covering the opening 121. The hub cover 122 has a central hole 1221 and a shaft hole 1222. The central hole 1221 is suitable for the central shaft of the reducer 17 to pass through. The display panel gripping robot 1 also includes a rotation drive motor 14. The rotation shaft of the rotation drive motor 14 passes through the shaft hole 1222 to connect to the reducer 17. A support part 1223 is provided on the side of the hub cover 122 facing the reducer 17. The support part 1223 is connected to the outer periphery of the reducer 17. A heat dissipation hole 12231 is provided on the side wall of the support part 1223.

[0049] The base 11 serves as the foundation platform for the display panel gripping robot 1, bearing the crucial task of supporting all upper-level components. The base 11 features a receiving slot 111 suitable for installing the reducer 17, ensuring its stable installation and facilitating maintenance and replacement. The rotating arm 12, rotatably connected to the base 11, is a key component enabling the display panel gripping robot 1 to grasp objects in multiple directions. The rotating end of the rotating arm 12 has an opening 121 suitable for the reducer 17 to pass through, making the installation and replacement of the reducer 17 exceptionally simple, eliminating the need to disassemble the entire robot structure, significantly saving maintenance time and reducing labor intensity. A bearing 13 is installed between the base 11 and the rotating end of the rotating arm 12. The bearing 13 ensures smooth, low-friction operation of the rotating arm 12 during horizontal rotation. Furthermore, the bearing 13 not only supports the rotating arm 12 but also indirectly bears the weight of subsequent components such as the lifting arm 15 and the mechanical gripper 16, ensuring the stability and precision of the entire robot's movement.

[0050] According to the first aspect of the present application, the display panel gripping robot 1 has a receiving groove 111 on the base 11 specifically for installing the reducer 17. The rotating end of the rotating arm 12 has an opening 121 adapted to the reducer 17, allowing the reducer 17 to directly enter and exit through this opening 121. Therefore, during the replacement of the reducer 17, it is not necessary to disassemble the entire rotating arm 12 or other parts of the robot, simplifying the disassembly process and significantly reducing the time required to replace the reducer 17. The bearing 13 provided between the base 11 and the rotating end of the rotating arm 12 helps support the weight and movement of the rotating arm 12, while reducing the burden on the reducer 17. The use of the bearing 13 makes the overall rotation of the rotating arm 12 more stable, improving the operating efficiency and accuracy of the display panel gripping robot 1. By providing the opening 121 on the rotating arm 12, combined with the design of the bearing 13, the replacement of the reducer 17 becomes simple and quick. The operator can directly remove the reducer 17 through the opening 121 without affecting the bearing 13 or other components, avoiding frequent disassembly and assembly of heavy components and reducing potential hazards during maintenance. The hub cover 122 protects the reducer 17 from external environmental influences and provides an interface for easy replacement of the reducer 17. The hub cover 122 is mounted on the rotating arm 12, precisely covering the opening 121 of the reducer 17. This ensures the cleanliness and safety of the reducer 17, preventing dust and impurities from entering and affecting its normal operation. When replacing the reducer 17, first open the hub cover 122 to expose the opening 121, then remove the reducer 17. The central hole 1221 and shaft hole 1222 on the hub cover 122 correspond to the central shaft of the reducer 17 and the rotating shaft of the drive motor 14, respectively, ensuring smooth power transmission from the drive motor 14 to the reducer 17, thereby controlling the rotation of the rotating arm 12. By adjusting the reduction ratio of the reducer 17, the stability and accuracy of the rotating arm 12 when gripping the display panel can be ensured. Even if the rotation speed of the drive motor 14 is high, the reducer 17 can adjust it to a suitable speed for the gripping action, avoiding the risk of unstable gripping or damage to the display panel due to excessive speed. The maximum outer dimension of the support part 1223 is smaller than the inner diameter of the bearing 13, allowing the support part 1223 to be embedded inside the bearing 13, ensuring the installation of the reducer 17. At the same time, the bottom of the support part 1223 abuts against the reducer 17, which provides additional physical support for the hub cover 122, reducing defects such as displacement and abnormal noise of the hub cover 122 caused by vibration or load, enhancing the overall structural robustness, and ensuring reliable protection of the reducer 17 by the hub cover 122. By opening heat dissipation holes 12231 on the side wall of the support part 1223, the heat generated by the reducer 17 during operation can be directly dissipated, preventing heat accumulation and overheating.Proper heat dissipation measures help maintain the reducer 17 within an ideal temperature range, reducing problems such as material aging and lubrication failure caused by overheating, and extending its service life. The opening design on the side wall reduces the risk of dust and other particles falling directly into the reducer; dust falling from above is unlikely to enter the interior directly through the side openings.

[0051] Furthermore, the combined use of bearing 13 and reducer 17 allows bearing 13 to bear part of the load, reducing the pressure on reducer 17 and enabling it to operate under better conditions. This reduces wear and failure rate, enhancing not only the load-bearing capacity and rotational stability of the display panel gripping robot 1 but also extending the service life of reducer 17. In summary, the display panel gripping robot 1 provided in this application embodiment can ensure the protective performance and heat dissipation effect of reducer 17 based on its easily detachable structure.

[0052] In some embodiments of this application, the heat dissipation hole 12231 includes at least one of a circular hole, an oblong hole, and a square hole. These different shapes of heat dissipation holes 12231 can be selected or combined according to specific heat dissipation requirements. For example, a circular heat dissipation hole has better pressure resistance; an oblong hole can provide a larger total ventilation area without significantly increasing the area of ​​a single hole; and a square hole is convenient for manufacturing and arrangement. By using these different shapes of heat dissipation holes 12231 in combination, the heat dissipation effect can be flexibly adjusted according to the characteristics of the local heat load.

[0053] like Figure 6 As shown, in some embodiments of this application, a dust filter 12232 is provided in the heat dissipation hole 12231. The dust filter 12232 can effectively prevent external dust, particles, etc. from entering the reducer 17, preventing these contaminants from affecting the working performance of the reducer 17 or causing premature wear. The dust filter 12232 can be directly embedded into the heat dissipation hole, or it can be designed to be detachable for easy regular cleaning or replacement. For larger heat dissipation holes, a frame can be added at its inlet to fix the dust filter 12232.

[0054] For applications requiring enhanced protection, a multi-layer filtration structure can be used. For example, a coarse filter can be used on the outer layer to intercept large particles, while a fine filter can be used on the inner layer to capture tiny particles. This can improve the filtration effect and extend the service life of the dust filter 12232.

[0055] like Figure 5As shown, in some embodiments of this application, the bearing 13 includes an inner ring 131 and an outer ring 132. The inner ring 131 is connected to the base 11, and the outer ring 132 is connected to the rotating arm 12. A ball roller is disposed between the outer ring 132 and the inner ring 131. The inner ring 131 is firmly connected to the base 11, which is the basic support part 1223 of the display panel gripping robot 1, bearing the weight and load of the entire display panel gripping robot 1. The outer ring 132 is connected to the rotating arm 12. When the rotating arm 12 rotates, the outer ring 132 moves accordingly, while the inner ring 131 remains stationary. The rotating arm 12 rotates freely without affecting the stability of the base 11. The ball roller is placed between the inner ring 131 and the outer ring 132, reducing friction through rolling rather than sliding. This greatly reduces energy loss during rotation, improves efficiency, and also extends the service life of the bearing 13. Because of the bearing 13, when the reducer 17 is replaced, the base 11, bearing 13 and rotating arm 12 can be kept in the same state. Only the part directly connected to the reducer 17 needs to be disassembled, which greatly simplifies the maintenance process and improves maintenance efficiency.

[0056] Furthermore, in some embodiments of this application, the bearing 13 is sleeved on the outer periphery of the receiving groove 111. The bearing 13 is positioned close to the reducer 17. When the reducer 17 needs to be replaced, the hub base 11 connected to the reducer 17 is first removed, and then the connection between the reducer 17 and the hub base 11 is disconnected, thus completing the replacement. Throughout the process, the base 11, bearing 13, and rotating arm 12 do not need to be separated, maintaining the integrity of the structure. This reduces the complexity and workload of replacing the reducer 17, shortens the replacement time, improves maintenance efficiency, and ensures operational safety.

[0057] like Figure 7 As shown in some embodiments of this application, the display panel gripping robot 1 further includes a lifting arm 15 and a mechanical gripper 16. The lifting arm 15 is connected to the swing end of the rotating arm 12, and the mechanical gripper 16 is connected to the lifting end of the lifting arm 15. The rotating arm 12 is adapted to drive the lifting arm 15 to move horizontally, and the lifting arm 15 is adapted to drive the mechanical gripper 16 to move vertically. The lifting arm 15 is connected to the swing end of the rotating arm 12 and can move along with the horizontal rotation of the rotating arm 12. The lifting arm 15 is responsible for supporting the mechanical gripper 16. Through its own lifting function, the mechanical gripper 16 can move up and down vertically to accurately grip and place the display panel. The rotating arm 12 expands the robot's horizontal operating range, and the lifting arm 15 expands the robot's vertical operating range, improving the multi-scenario adaptability and multi-functionality of the display panel robot.

[0058] The mechanical gripper 16 is used to grasp the display panel. It can grasp the display panel by vacuum adsorption or by mechanical clamping.

[0059] Vacuum adsorption gripping involves multiple suction cups mounted on the mechanical gripper 16. These suction cups utilize a vacuum pump to generate negative pressure, causing them to firmly adhere to the surface of the display panel. This method is suitable for gripping relatively flat display panels, providing a stable and damage-free grip, and is particularly suitable for fragile or sensitive panel materials. Another advantage of vacuum adsorption gripping is that it can evenly distribute pressure across the display panel, preventing excessive localized stress that could cause panel deformation or damage.

[0060] Mechanical gripping involves using the clamps or claws at the end of the mechanical gripper 16 to grasp the display panel. The clamp design can be varied; for example, it can employ a pliers-like structure, securing the display panel by closing the gripping arms on both sides; or it can use a finger-like structure, stabilizing the display panel through multi-point contact. Mechanical gripping is suitable for display panels with irregular shapes or surfaces unsuitable for vacuum adsorption, such as the edges of the display panel or panels with certain special shapes. Furthermore, the mechanical gripper can provide stronger gripping force, making it suitable for heavier or larger display panels.

[0061] like Figure 7 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 track groove 112 extends horizontally. The track groove 112 on the base 11 allows the rotating arm 12 to slide horizontally, enabling it to not only rotate on the base 11 but also move linearly horizontally, greatly expanding the working range and flexibility of the display panel gripping robot 1. The track groove 112 ensures smooth movement of the rotating arm 12 and provides additional degrees of freedom for the mechanical gripper 16, allowing it to reach different positions on the production line, improving its application efficiency and applicability in the display panel production line. Because the track groove 112 extends horizontally, the display panel gripping robot 1 can cover a wide area of ​​the production line, making it particularly suitable for applications requiring the handling and positioning of display panels over a large area. For example, in a large display panel production line, the rotating arm 12 slides along the track groove 112 on the base 11 to drive the mechanical gripper 16 to move between long process stations without human intervention, thus realizing the automated and intelligent handling of display panels.

[0062] Furthermore, the track groove 112 enhances the operational safety of the display panel gripping robot 1. Because the rotating arm 12 can slide smoothly on the predetermined track, the risk of accidental collisions or deviations is avoided, reducing potential accidents on the production line and ensuring the safety of operators and equipment. This design also facilitates the planning and control of the movement path of the mechanical gripper 16, making the layout and management of the production line more orderly and efficient.

[0063] like Figure 7 As shown, in some embodiments of this application, the mechanical gripper 16 includes at least two telescopic arms 161 and a display panel fork 162; adjacent telescopic arms 161 are rotatably connected, and the display panel fork 162 is located at the end of the last telescopic arm 161. The multi-section design of the telescopic arms 161 provides a greater range of extension and flexibility, enabling the mechanical gripper 16 to reach different positions on the production line, even in narrow or hard-to-reach spaces. Adjacent telescopic arms 161 are connected by a rotating joint, which allows the mechanical gripper 16 to extend and retract not only in a straight line but also to rotate within a certain angle, improving gripping accuracy and adaptability. The display panel fork 162 ensures the safety of the display panel during handling, reduces panel damage caused by improper gripping, and guarantees the yield and reliability of the display panel.

[0064] 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.

[0065] According to the display panel production line provided in the second aspect of this application, the display panel is transferred using a display panel gripping robot 1. Specifically, the receiving groove 111 on the base 11 is specifically designed for mounting the reducer 17, while the rotating end of the rotating arm 12 has an opening 121 adapted to the reducer 17. The reducer 17 can directly enter and exit through this opening 121. Therefore, during the replacement of the reducer 17, it is not necessary to disassemble the entire rotating arm 12 or other parts of the robot. The disassembly process is simple, significantly reducing the time required to replace the reducer 17. The bearing 13 provided between the base 11 and the rotating end of the rotating arm 12 helps to support the weight and movement of the rotating arm 12, while reducing the burden on the reducer 17. The use of the bearing 13 makes the overall rotation of the rotating arm 12 more stable, improving the operating efficiency and accuracy of the display panel gripping robot 1. By providing the opening 121 on the rotating arm 12 and combining it with the design of the bearing 13, the replacement of the reducer 17 becomes simple and quick. The operator can directly remove the reducer 17 through opening 121 without affecting the bearing 13 or other components, avoiding frequent disassembly and assembly of heavy components and reducing potential hazards during maintenance. Furthermore, the combined use of bearing 13 and reducer 17 allows bearing 13 to bear a portion of the load, reducing the pressure on reducer 17 and enabling it to operate under optimal conditions. This reduces wear and failure rate, enhancing the load-bearing capacity and rotational stability of the display panel gripping robot 1, and extending the service life of reducer 17. In summary, the display panel production line provided in this embodiment offers simple and quick equipment troubleshooting, ensuring the production schedule of display panels.
