Description

Technical Field

[0001] This application relates to the field of display panel repair technology, and in particular to a rotary multi-station panel repair system. Background Technology

[0002] Currently, the industry commonly uses linear assembly lines and single-station workstations for the repair and processing of flat panel components such as display panels. In a linear assembly line, multiple single-function devices are arranged in a straight line, and panels are sequentially transported to each device for processing by conveyor belts or robotic arms. In a single-station workstation, operators must manually change tools on the same workbench or manually move panels between different devices to complete all processes. While linear assembly lines achieve process decomposition, panels must complete the previous process before moving to the next. Delays at any station slow down the entire line. In a single-station workstation, the time spent moving panels between processes cannot be eliminated, and all processes must be performed sequentially, resulting in low productivity.

[0003] Therefore, how to provide a panel repair system with high production efficiency is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0009] Preferably, the processing equipment at the grinding station includes a belt sander and a polishing machine. The belt sander is located on one side of the grinding station and is used to rough grind the edge of the panel. The polishing machine is located on the other side of the grinding station and is used to fine polish the edge of the panel after rough grinding.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] As described in the background section, the industry currently commonly employs linear assembly lines and single-station workstations for the repair and processing of flat panel components such as display panels. In a linear assembly line, multiple single-function devices are arranged in a straight line, with panels sequentially transported to each device by conveyor belts or robotic arms for processing. In a single-station workstation, operators must manually change tools on the same workbench or manually move panels between different devices to complete all processes. While linear assembly lines achieve process decomposition, panels must complete the preceding process before moving to the next station; any delay at any station slows down the entire line. In a single-station workstation, the time spent moving panels between processes cannot be eliminated, forcing all processes to be performed sequentially, resulting in low productivity.

[0021] Based on this, this application provides a rotary multi-station panel repair system, which aims to solve the technical problem of low production line efficiency in the prior art.

[0022] The embodiments of this application will be analyzed in detail below with reference to the accompanying drawings.

[0023] refer to Figure 1 A rotary multi-station panel repair system includes: a base 1; a rotary mechanism 2 rotatably mounted on the base 1, with at least six station fixtures 20 evenly distributed circumferentially on the rotary mechanism 2 for supporting and fixing the panel; and a controller electrically connected to the rotary mechanism 2 for controlling the rotation of the rotary mechanism 2 so that each station fixture 20 stops sequentially at a preset processing station 3; wherein each processing station 3 is equipped with processing equipment communicatively connected to the controller, and the processing station includes at least a pre-processing station 30, an inspection station 31, a repair station 32, a polishing station 33, an assembly station 34, and a material unloading station 35.

[0024] The intermittent rotation of the turntable mechanism 2 enables parallel operation of various processes. When one panel is being processed at a certain station, other stations can simultaneously operate on other panels, eliminating the waiting time between processes in traditional assembly lines and greatly shortening the total processing cycle of a single panel. Furthermore, a panel completes the pre-processing and assembly processes on the same station fixture 20, and is only removed during final unloading. This avoids the cumulative positioning errors caused by repeated disassembly, reassembly, handling, and repositioning between different devices, ensuring the processing quality of the system.

[0025] In a preferred embodiment, the processing equipment at the pretreatment station 30 includes a dust collector, an electrostatic eliminator, and a cleaning machine. The dust collector is located above the pretreatment station 30 and is used to remove dust from the panel. The electrostatic eliminator is located on one side of the pretreatment station 30 and is used to eliminate static electricity from the panel. The cleaning machine is located on the other side of the pretreatment station 30 and is used to wipe the panel.

[0026] The dust collector, static eliminator, and cleaning machine work together. First, the dust collector removes the floating dust, then the static eliminator prevents the dust from being re-adsorbed due to static electricity, and finally the cleaning machine wipes the surface. This forms the initial panel preparation process, laying a dust-free foundation for subsequent testing and repair, and avoiding damage caused by incomplete cleaning.

[0027] In a preferred embodiment, the processing equipment at inspection station 31 includes an optical inspection instrument and a microscope. The optical inspection instrument is used to scan the panel to locate the defect coordinates, and the microscope is used to move to the defect coordinates to acquire images and capture defect images.

[0028] The process involves an optical inspection instrument for rapid initial defect screening and location, followed by a microscope for further imaging and verification. This combination of methods balances inspection efficiency and accuracy. This approach not only enables rapid defect detection but also allows for precise determination of the defect type and extent, providing a data foundation for subsequent repairs.

[0029] In a preferred embodiment, the processing equipment at the repair station 32 includes a laser, which is movably disposed above the repair station 32 for moving to the defect coordinates and emitting a laser beam to act on the defect of the panel according to the defect image.

[0030] The laser can automatically locate and adjust its parameters to perform operations for different defects, such as scratches and bubbles, based on the coordinates and image information provided by the previous process.

[0031] In a preferred embodiment, the processing equipment at the grinding station 33 includes a belt sander and a polishing machine. The belt sander is located on one side of the grinding station 33 and is used to rough grind the edge of the panel. The polishing machine is located on the other side of the grinding station 33 and is used to fine polish the edge of the panel after rough grinding.

[0032] The process involves first using a belt sander to remove burrs and uneven areas from the panel, followed by a polishing machine for finishing. This progressive processing method ensures both efficiency and smoothness of the panel edges, thus enhancing the aesthetics of the panel products.

[0033] In a preferred embodiment, the processing equipment at assembly station 34 includes a laminating machine and a fastening mechanism. The laminating machine is used to align and press the panel and its back panel together, and the fastening mechanism is used to fix the pressed panel and back panel together.

[0034] The bonding machine ensures the alignment and initial bonding of the panel and back panel, while the fastening mechanism achieves final structural fixation, improving alignment accuracy and ensuring the structural stability of the finished product.

[0035] As a preferred embodiment, the laminating machine integrates a pressure sensor for real-time monitoring of the bonding force applied by the laminating machine to the panel and its backing.

[0036] The pressure sensor ensures that each pressing is performed within a safe pressure range, preventing poor adhesion due to insufficient pressure or damage to the panel and leakage of the liquid crystal due to excessive pressure, thus improving the controllability of the assembly process.

[0037] In a preferred embodiment, the processing equipment at the unloading station 35 includes an unloading robot and an anti-static tray. The unloading robot is used to transfer the processed panels to the anti-static tray.

[0038] Among them, the unloading robot replaces manual handling and, combined with anti-static chucks, avoids scratches or electrical damage to the finished panels caused by human intervention or electrostatic discharge in the final stage, thus ensuring the yield of panel products.

[0039] In a preferred embodiment, the workstation fixture 20 is an anti-static fixture, which integrates an in-position sensor for monitoring whether the panel is in position.

[0040] Among these features, the anti-static fixture eliminates the risk of damage to the panel circuitry caused by static electricity generated by friction within the fixture itself. The in-position sensor prevents the equipment from malfunctioning when an empty fixture enters the processing station or when the panel is not clamped, thus improving system safety.

[0041] In a preferred embodiment, the system also includes an outer cover, on which observation windows and safety doors are provided for each processing station 3.

[0042] The outer casing isolates dust and noise generated during repair and polishing processes within the system, maintaining a clean production environment and reducing noise pollution. The design of safety doors and observation windows ensures worker safety and prevents accidental entry into hazardous areas, while also allowing for real-time monitoring and necessary intervention of equipment operating status at different processing stations.
