Demand is high and widespread. Traditional high-bay warehouses rely on manual or forklift handling for goods movement, resulting in low efficiency and high costs. Recently emerging intelligent high-bay warehouses typically utilize rigid robotics for handling, resulting in limited speeds. Furthermore, the mobile platforms require motors, which are heavy and energy-intensive, necessitating improvements. Summary of the Invention

[0003] The purpose of the present invention is to solve the technical problems raised in the above background technology.

[0004] The present invention adopts the following technical solution: a vertical warehouse material handling robot, including a frame component, wherein a drive component, a moving platform component, an end effector component, a cable assembly and a control system are arranged inside the frame component, the frame component contains a frame body inside, the four corners of the frame body are fixedly connected with reinforcement members, the bottom of the frame body is fixedly installed with a fixing plate, and the surface of the frame body is fixedly installed with a mounting plate and a drive base.

[0005] Preferably, the driver assembly includes a drive group base plate and a first servo motor. A bearing seat and a reducer mounting plate are fixedly mounted on the surface of the drive group base plate. A servo motor encoder is fixedly mounted on the tail of the first servo motor. A first reducer is fixedly mounted on the output end of the first servo motor. An output shaft is fixedly mounted on the output end of the first reducer. A rope drum is fixedly mounted on the surface of the output shaft. A rope pressure block is fixedly mounted on the surface of the rope drum. A rope is fixedly mounted inside the rope pressure block. A bearing cap is fixedly mounted on the surface of the bearing seat. Here, the first reducer is fixed to the frame body via the driver base. By activating the first servo motor, the rope drum is driven to rotate, which drives the rope to move and cooperate with the fixed pulley, thereby achieving the lifting and lowering of the movable platform assembly.

[0006] Preferably, the movable platform assembly includes a mobile platform frame, a cable-threading plate fixedly mounted on its outer surface, a tension sensor fixedly mounted on its surface, a cable-threading point fixedly mounted on its surface, and a telescopic cylinder fixedly mounted on its inner surface, a positioning electromagnet fixedly mounted on the end of the telescopic cylinder. Here, when the mobile platform frame is moved to a predetermined position by the traction of the rope, the telescopic cylinder temporarily attracts the electromagnet to the vertical warehouse, temporarily connecting the movable platform assembly to the vertical warehouse and ensuring stable handling. The tension sensor monitors the rope tension in real time, ensuring a safe and reliable handling process.

[0007] Preferably, the end effector assembly includes an upper fork support, a second servo motor fixedly mounted on the surface of the upper fork support, a second reducer fixedly mounted on the output end of the second servo motor, and a lower fork support slidably connected to the interior of the upper fork support. A rack and a clamping cylinder are fixedly mounted on the surface of the lower fork support, and a clamping claw is fixedly mounted on the output end of the clamping cylinder. Here, when the moving platform assembly reaches the predetermined position, the second servo motor drives the second reducer to cause the rack to drive the lower fork support to slide into the vertical warehouse. The clamping claw then opens or closes through the operation of the clamping cylinder, accurately grasping or releasing materials, ensuring efficient and accurate handling.

[0008] Preferably, the cable assembly includes a fixed pulley support, the fixed pulley support having a fixed pulley shaft rotatably connected thereto, and a fixed pulley fixedly mounted on the surface of the fixed pulley shaft. The fixed pulley cooperates with the cable to ensure that the cable remains stable during movement, preventing friction or jamming that could affect overall operating efficiency, further ensuring smooth and reliable material handling.

[0009] Preferably, the control system includes a user interface display screen, a switch button and an emergency stop button fixedly mounted on the surface of the control system, and a power distribution board and drive components are internally contained within the control system. Here, the user interface display screen displays the system status in real time, allowing the operator to conveniently operate the switch button and emergency stop button for rapid response and emergency braking. The power distribution board and drive components work together to ensure stable and efficient system operation, coordinated operation of all components, and enhanced intelligence and safety of the overall handling system.

[0010] Preferably, the driver base is fixedly mounted to the drive assembly bottom plate, and the mounting plate is fixedly mounted to the fixed wheel axle support.

[0011] Preferably, the rope is wrapped around the surface of a rope drum, rotatably connected to a fixed pulley, and one end of the rope is fixedly mounted between a rope anchor point. Here, the synergistic effect of the rope, the rope drum, and the fixed pulley ensures uniform tension during the stretching and retraction process, effectively preventing the rope from becoming loose or overtightened, and improving the stability and accuracy of the handling process.

[0012] Preferably, the reducer mounting plate is fixedly mounted to the first reducer, and the output shaft is rotationally connected to the bearing seat. The secure connection between the reducer mounting plate and the first reducer ensures smooth and unimpeded rotation between the output shaft and the bearing seat, effectively reducing transmission errors, improving mechanical operating accuracy, and ensuring efficient coordination of all components.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the present invention, a stable and flexible structural system is formed by the provision of a frame body, reinforcement, fixing plate, mounting plate, driver base, driver group bottom plate, reducer mounting plate, and bearing seat, which effectively improves the load-bearing capacity and impact resistance of the robot during operation. The first servo motor, servo motor encoder, first reducer, output shaft, rope winding drum, rope pressure block, and bearing cover are provided to achieve precise power transmission and rope control. The servo motor encoder provides real-time feedback on the motor rotation angle to achieve closed-loop control of the motor rotation, ensuring accurate positioning and efficient operation of the handling process.

[0015] 2. In the present invention, by providing a telescopic cylinder and an electromagnet, after the mobile platform frame moves to the predetermined position of the vertical warehouse, the electromagnet with power applied to its output end can be adsorbed on the vertical warehouse by starting the telescopic cylinder, so that the mobile platform frame is temporarily connected to the vertical warehouse, and the picking and placing of goods are more stable. The tension sensor and the fixed rope point can be used to monitor the rope tension in real time to ensure the stability of the goods during the transportation process. By providing a second servo motor, a second reducer, a rack, a clamping cylinder, and a clamping claw, automatic control of the clamping and release of goods can be achieved, thereby improving the transportation efficiency.

[0016] 3. In the present invention, ropes, fixed wheel shaft supports, fixed wheel shafts, and fixed pulleys are provided to pull the movable platform assembly. The movable platform assembly has four directions of movement and is pulled by eight ropes. The ropes in the four directions will always remain taut to ensure that the movable platform assembly can be stably suspended at any position, avoiding imbalance caused by the slack of a single rope. The structure is simple, the equipment can be quickly assembled, the cost is low, and the replacement of wearing parts is easy. Compared with ordinary robotic arms, the use of rope drive uses fewer parts to achieve a larger working space, and the power consumption is lower than that of rigid robots, reducing factory energy consumption, and can be widely used in industrial manufacturing.

[0034] Working principle: When an item needs to be placed at point A in the vertical warehouse, the operator selects the target position A through the user interface display screen 61 and sends a signal to the robot control system 6. After receiving the signal, the robot can display the task information through the user interface display screen 61. After confirmation, the operator presses the switch button 62 to start the system. The four servo motors of the frame are linked at the same time. The first servo motor 22 installed on the frame body 11 is started to drive the first reducer 26 to drive the output shaft 27 to rotate, so that the rope drum 28 rotates, and the rope 210 moves accordingly. The rope 210 will change in length under the guidance of the fixed pulley 53. Similarly, the other three servo motors are linked, and the lengths of the ropes in the other three directions change synchronously. The ropes in the four directions always ensure the balance of the mobile platform. Thereby, the mobile platform frame 31 on the fixed cable point 34 is driven to move. When the mobile platform frame 31 moves to the set point A, the robot control system 6 automatically stops the first servo motor 22 to ensure that the mobile platform frame 31 is accurately positioned. At the same time, the telescopic cylinder 35 extends, so that the electromagnet 36 at its output end is adsorbed on the vertical warehouse frame, temporarily fixing the mobile platform frame 31 to prevent shaking. Then the second servo motor 42 is operated to rotate the second reducer 43 to move the lower fork support 44 to the inside of point A of the vertical warehouse through the rack 45. After moving to the predetermined position, the second servo motor 42 stops running, and the output end of the clamping cylinder 46 will extend forward, so that the clamping claw 47 cancels the clamping of the object and places the object steadily at point A of the vertical warehouse. 46 is retracted, the lower fork support 44 returns to the initial position, the second servo motor 42 runs in the opposite direction, the telescopic cylinder 35 contracts, the electromagnet 36 is released, the mobile platform frame 31 returns to the free state, and the first servo motor 22 is started again to retract the rope 210 by rotating the rope winding drum 28, and the mobile platform frame 31 returns to the initial point. The outbound principle is as described above, and the process is reversed. The system automatically records the task completion status and updates the inventory information to ensure real-time data synchronization. The operator can view the task details and historical records through the interface. The emergency stop button 63 is located on the side of the user interface display screen 61. It is eye-catching in red, which is convenient for the operator to quickly identify and press it in an emergency to ensure a safe shutdown. The system immediately interrupts the current task to prevent accidents.

[0035] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields.
