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, especially the popularity of thin-film LCD and OLED displays in portable devices, higher requirements are being placed on the production process of these display panels. The manufacturing process involves processes such as deposition, photolithography, and etching, which typically require the use of display panel handling robots to transfer the display panels.

[0003] Existing display panel gripping robots typically include a lifting mechanism and a gripping mechanism. The lifting mechanism is used to adjust the gripping height of the gripping mechanism, but the lifting mechanism generates foreign objects during operation. These foreign objects can cause contamination of the lifting mechanism and even the display panel, thereby affecting the production quality of the display panel. Utility Model Content

[0004] In order to solve at least one of the technical problems existing in the background art, this application provides a display panel grasping robot that can effectively collect foreign objects, prevent these foreign objects from contaminating production equipment and production lines, and ensure the production quality 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, including a lifting arm support frame, a lifting arm and a grasping arm. The lifting arm support frame is provided with a first linear motion mechanism, a first brake and a first foreign object collector. The first brake is adapted to brake the first linear motion mechanism. The first foreign object collector is disposed below the first brake and is adapted to collect foreign objects in the first brake. The first foreign object collector includes an intercepting net and an electrostatic adsorption plate arranged sequentially from top to bottom.

[0008] The lifting arm is connected to the first linear motion mechanism. The lifting arm is provided with a second linear motion mechanism, a second brake, and a second foreign object collector. The second brake is adapted to brake the second linear motion mechanism. The second foreign object collector is located below the second brake and is adapted to collect foreign objects in the second brake. The second foreign object collector includes an interception net and an electrostatic adsorption plate arranged sequentially from top to bottom.

[0009] The gripping arm is connected to the second linear motion mechanism;

[0010] The first linear motion mechanism is adapted to drive the lifting arm to move up and down, and the second linear motion mechanism is adapted to drive the gripping arm to move up and down.

[0011] The display panel grasping robot provided in the first aspect of this application has two main features: a foreign object collection mechanism and a dual braking system, achieved by respectively arranging a linear motion mechanism, a brake, and a foreign object collector on the lifting arm support frame and the lifting arm. Specifically, the foreign object collection mechanism refers to a first foreign object collector located below the first brake and a second foreign object collector located below the second brake. These two foreign object collectors can collect metal shavings or other foreign objects generated during the operation of the brakes, preventing foreign objects from spreading inside the robot or on the production line, reducing the risk of display panel contamination by foreign objects, and thus improving product quality. Furthermore, each foreign object collector includes an intercepting net and an electrostatic adsorption plate arranged sequentially from top to bottom. The intercepting net is located at the top and can first capture larger particles (such as metal shavings, plastic fibers, etc.). The electrostatic adsorption plate is located below the intercepting net and is specifically used to capture small particles (such as dust, fine fibers, etc.). Larger foreign objects are initially filtered out by an intercepting net, and then finer particles are processed by an electrostatic adsorption plate. This graded filtration mechanism greatly reduces the risk of foreign objects entering the robot or production line, preventing their spread in the production environment and thus reducing the possibility of display panel contamination. The dual braking system refers to a first brake on the lifting arm support frame to control the lifting and braking movement of the entire lifting arm; and a second brake on the lifting arm to control the lifting and braking movement of the gripping arm. This dual braking design allows for independent control of the lifting arm and gripping arm's movements, increasing the robot's flexibility and precision. Furthermore, the independent brakes enable more timely responses to emergency stop requests, enhancing the robot's operational safety. In summary, the display panel gripping robot provided in this application significantly improves performance and production efficiency, reduces production costs, and also helps ensure the cleanliness of the production environment and the safe and stable operation of the production line, thus guaranteeing the quality of the display panels.

[0048] like Figures 1 to 11 As shown, a first aspect of this application provides a display panel grasping robot 1, including a lifting arm support frame 11, a lifting arm 12, and a grasping arm 13. The lifting arm support frame 11 is equipped with a first linear motion mechanism 111, a first brake 112, and a first foreign object collector 113. The first brake 112 is adapted to brake the first linear motion mechanism 111. The first foreign object collector 113 is located below the first brake 112 and is adapted to collect foreign objects from the first brake 112. The first foreign object collector includes an intercepting net 17 and an electrostatic adsorption plate 18 arranged sequentially from top to bottom. The lifting arm 12 is connected to the first linear motion mechanism 111. The lifting arm 12 is equipped with a second linear motion mechanism 121, a second brake 122, and a second foreign object collector 123. The second brake 122 is adapted to brake the second linear motion mechanism 121. The second foreign object collector 123 is located below the second brake 122 and is adapted to collect foreign objects from the second brake 122. The second foreign object collector includes an intercepting net 17 and an electrostatic adsorption plate 18 arranged sequentially from top to bottom. The gripping arm 13 is connected to the second linear motion mechanism 121. The first linear motion mechanism 111 is adapted to drive the lifting arm 12 to move up and down, and the second linear motion mechanism 121 is adapted to drive the gripping arm 13 to move up and down.

[0049] Specifically, the lifting arm support frame 11 provides support and guidance to ensure the stable vertical movement of the lifting arm 12. Specifically, the first linear motion mechanism 111, the first brake 112, and the first foreign object collector 113 mounted on the lifting arm support frame 11 work together to ensure precise control and safety of the lifting arm 12. The first brake 112 brakes the first linear motion mechanism 111, enabling it to quickly stop the vertical movement of the lifting arm 12 when needed, ensuring safety. The first foreign object collector 113 is located below the first brake 112 and collects foreign objects generated during the operation of the first brake 112, such as metal shavings from wear. This prevents foreign objects from spreading, avoiding damage to internal robot parts, extending the equipment's lifespan, and maintaining a clean production environment, preventing foreign objects from contaminating the display panel 2.

[0050] A second linear motion mechanism 121 is installed on the lifting arm 12 to control the lifting movement of the gripping arm 13. A second brake 122 is responsible for braking the second linear motion mechanism 121 to ensure safety and accuracy during operation. A second foreign object collector 123 is located below the second brake 122 and also serves to collect foreign objects generated by the second brake 122, preventing them from adversely affecting the gripping arm 13 and the production line.

[0051] The gripping arm 13 is connected to the second linear motion mechanism 121 and is driven by the second linear motion mechanism 121 to perform lifting and lowering movements, thereby achieving accurate gripping and placement of the display panel 2.

[0052] According to the first aspect of the embodiment of this application, the display panel grasping robot 1 has two main features: a foreign object collection mechanism and a dual braking system. Specifically, the foreign object collection mechanism refers to a first foreign object collector 113 located below the first brake 112 and a second foreign object collector 123 located below the second brake 122. These two foreign object collectors can collect metal shavings or other foreign objects generated during brake operation, preventing foreign objects from spreading inside the robot or on the production line, reducing the risk of contamination of the display panel 2 by foreign objects, and thus improving product quality. Furthermore, each foreign object collector includes an intercepting net 17 and an electrostatic adsorption plate 18 arranged sequentially from top to bottom. The intercepting net 17 is located at the top and can first capture larger particles (such as metal shavings, plastic fibers, etc.). The electrostatic adsorption plate 18 is located below the intercepting net 17 and is specifically used to capture small particles (such as dust, fine fibers, etc.). Larger foreign objects are initially filtered out by the interception net 17, and then smaller particles are processed by the electrostatic adsorption plate 18. This graded filtration mechanism greatly reduces the risk of foreign objects entering the robot or production line, and prevents foreign objects from spreading in the production environment, thereby reducing the possibility of contamination of the display panel 2. The dual braking system refers to the presence of a first brake 112 on the lifting arm support frame 11 to control the lifting and braking movement of the entire lifting arm 12; and a second brake 122 on the lifting arm 12 to control the lifting and braking movement of the gripping arm 13. This dual braking design allows for independent control of the movement of the lifting arm 12 and the gripping arm 13, increasing the robot's flexibility and precision; on the other hand, the independent brakes can respond more promptly to emergency stop requirements, enhancing the safety of the robot's operation. In summary, the display panel gripping robot 1 provided in this application embodiment significantly improves performance and production efficiency, reduces production costs, and also helps to ensure the cleanliness of the production environment and the safe and stable operation of the production line, thus ensuring the production quality of the display panel 2.

[0053] In addition, the two-stage filtration system provides dual protection, ensuring that even if one stage fails or becomes saturated, the other stage can continue to function, guaranteeing the normal operation of the system.

[0054] In some embodiments of this application, the surface of the interceptor 17 is coated with a hydrophobic and oleophobic coating; the surface of the electrostatic adsorption plate 18 is coated with an antistatic polymer layer.

[0055] Hydrophobic and oleophobic coatings typically employ fluorocarbon compounds or siloxanes, which possess extremely low surface energy, effectively repelling water and grease. These coatings significantly reduce the adhesion of particulate matter (especially oily particles) to the interceptor mesh 17, making particles easier to remove and reducing cleaning frequency and difficulty. Furthermore, the coating effectively prevents corrosion and oxidation, enhancing the durability of the interceptor mesh 17, extending its service life, and reducing replacement and maintenance costs.

[0056] The antistatic polymer layer is typically made of conductive polymers (such as polyaniline, polypyrrole, etc.) or composite materials containing conductive fillers (such as carbon nanotubes, metal powders, etc.). These materials provide excellent antistatic properties without significantly affecting adsorption performance. The antistatic polymer layer effectively releases static charge, preventing static buildup and thus avoiding additional dust or particulate matter adhesion due to electrostatic attraction, maintaining the cleanliness and adsorption efficiency of the electrostatic adsorption plate 18. By suppressing static buildup, the possibility of particulate matter being re-electrified or adhering to other components due to static electricity is reduced, further lowering the risk of secondary pollution. The antistatic polymer layer not only prevents static buildup but also maintains a high voltage state of the electrostatic adsorption plate 18, ensuring its effective adsorption of fine particulate matter and improving overall adsorption efficiency.

[0057] The interception net 17 and the electrostatic adsorption plate 18 optimize their respective functions through hydrophobic and oleophobic coatings and antistatic polymer layers, respectively, which significantly improves the capture efficiency of different types of foreign objects.

[0058] In some embodiments of this application, the mesh diameter of the interceptor net 17 ranges from 0.5 mm to 2 mm. The mesh diameter of the interceptor net 17 refers to the size of the mesh openings, i.e., the maximum width of each mesh opening. A 0.5 mm mesh is suitable for capturing smaller particles, such as fine dust and fibers; this size of mesh can filter tiny particles more finely. A 2 mm mesh is suitable for capturing larger foreign objects, such as larger metal fragments or plastic pieces. By appropriately selecting the mesh size, the capture capability of the interceptor net 17 can be adjusted according to actual needs. For different types of foreign objects, selecting an appropriate mesh size can maximize its capture efficiency, ensuring that most foreign objects are effectively intercepted.

[0059] The mesh can be round, square, diamond, or other shapes. The mesh is detachable and replaceable. Through modular design, different mesh components can be flexibly replaced according to different working environments. For example, a smaller mesh size (such as 0.5 mm) can be selected in high-dust environments, while a larger mesh size (such as 2 mm) can be selected in environments with larger foreign objects.

[0060] In some embodiments of this application, a first high-pressure air nozzle is provided on the lifting arm support frame 11, which is adapted to spray high-pressure air into the interception net 17 and electrostatic adsorption plate 18 in the first foreign object collector 113; a second high-pressure air nozzle is provided on the lifting arm 12, which is adapted to spray high-pressure air into the interception net 17 and electrostatic adsorption plate 18 in the second foreign object collector 123.

[0061] The first high-pressure air nozzle is mounted on the lifting arm support frame 11, close to the first foreign object collector 113. It periodically, or based on sensor feedback, sprays high-pressure air into the interceptor mesh 17 and electrostatic adsorption plate 18 in the first foreign object collector 113 to remove accumulated dust and foreign objects. The second high-pressure air nozzle is mounted on the lifting arm 12, close to the second foreign object collector 123. It periodically, or based on sensor feedback, sprays high-pressure air into the interceptor mesh 17 and electrostatic adsorption plate 18 in the second foreign object collector 123 to remove accumulated dust and foreign objects.

[0062] Pressure differential sensors and particle concentration sensors are installed near the interception net 17 and electrostatic adsorption plate 18 to monitor the status of the filter layer in real time and transmit the data to the central control system. Based on the sensor feedback data, the intelligent scheduling system automatically adjusts the time interval and pressure of high-pressure air injection to optimize the cleaning effect.

[0063] The nozzles can be designed with adjustable angles to ensure that high-pressure air can cover the entire surface of the interception net 17 and the electrostatic adsorption plate 18 without leaving any blind spots.

[0064] The design of installing high-pressure air nozzles on the lifting arm support frame 11 and lifting arm 12 to spray high-pressure air into the interception net 17 and electrostatic adsorption plate 18 in the foreign object collector not only significantly improves cleaning efficiency, but also extends the service life of the equipment and enhances its reliability and adaptability.

[0065] like Figure 1 , Figures 5 to 8 As shown, in some embodiments of this application, the first linear motion mechanism 111 includes a first ball screw 1111, a first slider 1112, and a first drive motor 1113. The first slider 1112 is slidably connected to the first ball screw 1111, the first drive motor 1113 is connected to the first ball screw 1111, and the lifting arm 12 is connected to the first slider 1112. The second linear motion mechanism 121 includes a second ball screw 1211, a second slider 1212, and a second drive motor 1213. The second slider 1212 is slidably connected to the second ball screw 1211, the second drive motor 1213 is connected to the second ball screw 1211, and the gripping arm 13 is connected to the second slider 1212.

[0066] The first drive motor 1113 drives the first ball screw 1111 to rotate. Due to the thread, the first slider 1112 can slide up and down on the first ball screw 1111, converting rotational motion into linear motion. Correspondingly, the second drive motor 1213 drives the second ball screw 1211 to rotate. Due to the thread, the second slider 1212 can slide up and down on the second ball screw 1211, converting rotational motion into linear motion. Compared with traditional gear or chain drives, the ball screw drive method has lower friction and higher energy conversion efficiency, thereby improving the robot's energy utilization efficiency.

[0067] Furthermore, in order to ensure the stability of the first ball screw 1111 and the second ball screw 1211, ball screw support members 16 are provided at both ends of each ball screw.

[0068] like Figure 1 , Figures 5 to 8 As shown, in some embodiments of this application, the first linear motion mechanism 111 further includes a first conveyor belt 1114, a first pulley 11111 is provided on the first ball screw 1111, one end of the first conveyor belt 1114 is sleeved on the first pulley 11111, and the other end of the first conveyor belt 1114 is sleeved on the rotating shaft of the first drive motor 1113; the second linear motion mechanism 121 further includes a second conveyor belt 1214, a second pulley 12111 is provided on the second ball screw 1211, one end of the second conveyor belt 1214 is sleeved on the second pulley 12111, and the other end of the second conveyor belt 1214 is sleeved on the rotating shaft of the second drive motor 1213.

[0069] Specifically, in the first linear motion mechanism 111, the rotating shaft of the first drive motor 1113 is connected to the first pulley 11111 via the first conveyor belt 1114, thereby driving the first ball screw 1111 to rotate; in the second linear motion mechanism 121, the second drive motor 1213 is connected to the second pulley 12111 via the second conveyor belt 1214, driving the second ball screw 1211 to rotate. The non-rigid connection between the conveyor belt and the pulley reduces direct contact between the drive motor shaft and the ball screw, reducing wear and extending the equipment's service life. The conveyor belt has a certain degree of elasticity, absorbing the impact during motor start-up and stop, reducing vibration, making the movement smoother, and improving precision. Compared to gear drives, belt drives have lower noise, contributing to a quieter production environment. Under overload conditions, the conveyor belt may slip rather than break; this characteristic can serve as an overload protection mechanism, preventing damage to the motor and ball screw.

[0070] like Figures 9 to 10As shown in some embodiments of this application, the first linear motion mechanism 111 further includes a conveyor belt breakage detection sensor 1115, which is respectively disposed at the locations of the first pulley 11111 and the second pulley 12111. The conveyor belt breakage detection sensor 1115 can provide early warning of potential conveyor belt failures, allowing the maintenance team to replace or repair the conveyor belt before it completely breaks, avoiding sudden production line stoppages. By promptly detecting and replacing damaged conveyor belts, production interruptions caused by sudden failures are reduced, thereby improving the continuity and efficiency of the production line. Conveyor belt breakage can lead to machine malfunction and increase the risk of operator injury. The presence of the conveyor belt breakage detection sensor 1115 reduces the likelihood of such events, improving the safety standards of the working environment. Furthermore, the data from the conveyor belt breakage detection sensor 1115 can be recorded and analyzed to help predict the lifespan of the conveyor belt and optimize maintenance plans, further improving the reliability and efficiency of the equipment. Due to the installation of the conveyor belt breakage detection sensor 1115, maintenance personnel can quickly locate the problem area, reducing diagnostic time and making the maintenance process more efficient.

[0071] In some embodiments of this application, a first tilt detection sensor is provided on the lifting arm support frame 11, a second tilt detection sensor is provided on the lifting arm 12, and a third tilt detection sensor is provided on the gripping arm 13. These tilt detection sensors can monitor the attitude changes of the lifting arm support frame 11, the lifting arm 12, and the gripping arm 13 in real time. Once a tilt angle exceeding a preset safety range is detected, the system will immediately take corresponding measures, such as stopping movement or adjusting the attitude, to prevent the robot from tipping over or damaging the display panel 2. Continuous attitude monitoring helps to detect potential mechanical problems early, such as loose support or structural fatigue, thereby enabling timely preventative maintenance and reducing unexpected downtime.

[0072] like Figure 11As shown, in some embodiments of this application, the gripping arm 13 includes at least two telescopic arm sections 131 and a display panel fork 132; adjacent telescopic arm sections 131 are rotatably connected, and the display panel fork 132 is located at the end of the last telescopic arm section 131. Using at least two telescopic arm sections 131 combined with the display panel fork 132 significantly improves the flexibility and versatility of the gripping arm 13. The rotatable connection between adjacent telescopic arms 131 allows the arm to be freely adjusted in multiple directions, enabling the robot to adapt to display panels 2 of different sizes and shapes and operate precisely in confined spaces. The combination of multiple telescopic arm sections 131 and rotatable connections allows the gripping arm 13 to achieve multi-dimensional movement, flexibly adjusting its posture even in complex operating environments to accurately grip and place the display panel 2. The telescopic arm 131 can adjust its length according to actual needs, finding a suitable gripping point for both large and small display panels 2, thus improving the robot's versatility and applicability.

[0073] The display panel fork 132 is used to grip the display panel 2. It can grip the display panel 2 by vacuum adsorption or by mechanical clamping.

[0074] Vacuum adsorption gripping works as follows: multiple suction cups are installed on the display panel fork 132. These suction cups generate negative pressure through a vacuum pump, thus firmly adhering to the surface of the display panel 2. This method is suitable for gripping relatively flat display panels 2, 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 the pressure on the display panel 2, avoiding excessive localized force that could cause panel deformation or damage.

[0075] The mechanical gripping method involves using clamps or claws at the ends of the display panel fork 132 to grasp the display panel 2. The clamp design can be varied; for example, it can employ a pliers-like structure, securing the display panel 2 by closing the gripping arms on both sides; or it can use a finger-like structure, stabilizing the display panel 2 through multiple points of contact. This mechanical gripping method is suitable for situations where the display panel 2 has an irregular shape or a surface unsuitable for vacuum adsorption, such as the edges of the display panel 2 or panels with certain special shapes. Furthermore, the mechanical gripper can provide stronger gripping force, making it suitable for heavier or larger display panels 2.

[0076] like Figure 11As shown, in some embodiments of this application, the display panel gripping robot 1 further includes a base 14 and a rotating arm 15 rotatably connected to the base 14; a lifting arm support frame 11 is disposed at the swing end of the rotating arm 15; the rotating arm 15 is adapted to drive the lifting arm support frame 11 to move horizontally. The rotating arm 15 on the base 14 can achieve 360-degree rotation in the horizontal direction, which allows the lifting arm support frame 11 to drive the gripping arm 13 to cover a larger planar area. The gripping arm 13 is no longer limited to a single workstation, improving its applicability and efficiency on the production line.

[0077] like Figure 11 As shown, in some embodiments of this application, a track groove 141 is also provided on the base 14, and the rotating arm 15 is slidably connected to the track groove 141; the track groove 141 extends horizontally. The track groove 141 on the base 14 allows the rotating arm 15 to slide horizontally, enabling it to not only rotate on the base 14 but also move linearly horizontally, greatly expanding the working range and flexibility of the display panel gripping robot 1. The track groove 141 ensures smooth movement of the rotating arm 15 while providing additional degrees of freedom for the gripping arm 13, allowing it to reach different positions on the production line and improving its application efficiency and applicability in the display panel production line. Since the track groove 141 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 2 over a large area. For example, in a large display panel production line, the rotating arm 15 slides along the track groove 141 on the base 14 to drive the gripping arm 13 to move between long process stations without manual intervention, thus realizing the automated and intelligent handling of the display panel 2.

[0078] In some embodiments of this application, an opening suitable for the passage of a speed reducer is formed on the rotating end of the rotating arm 15 connected to the base 14; a bearing is provided between the base 14 and the rotating end of the rotating arm 15. The speed reducer is a key component for controlling the rotational speed and torque of the rotating arm 15. The opening designed at the connection between the rotating arm 15 and the base 14 ensures that the speed reducer can pass smoothly and be installed in the proper position, thereby achieving precise control of the rotation of the rotating arm 15. The reasonable layout and installation of the speed reducer not only simplifies the internal structure of the robot, but also facilitates the maintenance and repair of the speed reducer, improving overall maintainability. The bearing between the base 14 and the rotating arm 15 reduces friction between them, ensuring smoothness and stability during the rotation of the rotating arm 15. The bearing can withstand radial and axial loads, providing low-friction rotation, maintaining the precise operation of the robot and extending its service life.

[0079] 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.

[0080] The display panel production line provided according to the second aspect of this application integrates the display panel gripping robot 1 from any of the embodiments of the first aspect. This significantly improves production efficiency, product quality, and production line flexibility. The display panel gripping robot 1 can quickly and accurately grip and place display panels 2, reducing manual operation time and errors, accelerating the production process, and increasing overall output. The display panel gripping robot 1 incorporates various sensors and safety mechanisms, such as tilt detection sensors, brakes, and foreign object collectors, ensuring safety and environmental cleanliness during operation, reducing the occurrence of production accidents, improving production efficiency and product quality, and enhancing the overall intelligence level of the production line.
