[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 5 As shown, the first embodiment of the utility model provides a mechanical arm suction rod partition adjustment mechanism for carrying a flexible display panel, and the overall planning scheme is: the mechanical arm adopts a conventional mechanical arm support structure and a technical solution of a control principle, and on the basis of the purple, the mechanical arm is fixedly connected to the bracket frame, and a control area and multiple adsorption areas are set on the bracket frame, and each adsorption area is respectively provided with multiple suction rods, and each suction rod is adjustably connected to the bracket frame through an adjustment mechanism, so that the specification size of each adsorption area can be quickly adjusted through the adjustment mechanism.

[0028] A number of vacuum control valves 12 equal to the number of suction rods 21 are arranged in the control area, and each vacuum control valve 12 is respectively connected to a single suction rod 21 at a corresponding position, so that each suction rod can be independently controlled by an independently arranged vacuum control valve, thereby independently controlling the switching operation of a single suction nozzle.

[0029] Through the above-mentioned planned technical scheme, the purpose of zoning management of each adsorption area can be achieved, and the robot arm can adapt to the adsorption and handling needs of flexible display panels of various specifications and sizes without the need for frequent disassembly and installation; the operation is simple and fast, and it takes little time, and it can be adjusted in zones, compatible with the handling needs of flexible display panels of different specifications and sizes, and improves production efficiency.

[0030] Specifically, according to the design idea of ​​the technical solution of the partition adjustment mechanism of the robotic arm suction rod for carrying the flexible display panel, the bracket frame is set as a rectangular frame structure composed of a control end plate 1 and a bracket frame body 2, the control area is set on the control end plate 1, and the adsorption area is set on the bracket frame body 2. The control area and the adsorption area are also set separately, which is convenient for separating the installation and management of the control elements and the adsorption elements without interfering with each other.

[0031] A mounting connection boss 11 is arranged in the middle of the outer side of the control end plate 1, and the mounting connection boss can facilitate the bracket frame to be fixedly mounted and connected to the mechanical arm, which is stable and reliable.

[0032] During the actual operation, four suction rods 21 are respectively set in each adsorption area. The four suction rods in each adsorption area are respectively located at the top corners of a virtual rectangular ring. Each adsorption area can reliably adsorb the flexible display panel of corresponding specifications and sizes through the four suction rods at the top corners of the virtual rectangular ring. The flexible display panel is subjected to balanced force and has good adsorption and transportation stability.

[0033] Moreover, the suction rods of the multiple adsorption areas are located at the vertices of multiple concentric virtual rectangular rings, so that the multiple adsorption areas are multiple concentric overlapping rectangular areas, which can further reduce the size of the equipment, reduce the space occupied by the equipment, save production site costs and equipment cost investment, and improve space utilization.
