[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figs. 1-4 This utility model provides a board loading and unloading device for transporting boards, including a mobile trolley 1 and a support assembly. The support assembly includes a support base 2 for supporting the boards. Several sets of storage slots 3 are equidistantly provided on the top of the support base 2. A rotating roller 4 is slidably installed in the storage slots 3 and can rotate within the storage slots 3. Both ends of the rotating roller 4 are rotatably mounted on a rotating seat 5. The rotating seat 5 is fixedly connected to a mounting base 6. The bottom sides of the support base 2 respectively abut against the inclined surfaces of two sets of inclined seats 7. A first movable seat 8 is fixedly installed at the bottom of the inclined seat 7. Two sets of first movable seats 8 are symmetrically installed on a bidirectional lead screw 9. Four sets of guide seats 12 are fixedly installed around the support base 2. The guide seats 12 are slidably installed on guide rods 13, and a limit switch is threaded onto the top of the guide rods 13. The bottom of plate 14 and guide rod 13 are fixedly installed on mounting base 6. Spring 15 is slidably sleeved on the surface of guide rod 13. The bottom of spring 15 abuts against guide seat 12, and the top of spring 15 abuts against limit plate 14. Bidirectional screw 9 is rotatably installed in adjustment groove 16 opened in the middle of the top of mounting base 6. First moving seat 8 is slidably engaged with adjustment groove 16. Adjustment handle 17 is installed on one side of the bottom of mounting base 6. Adjustment handle 17 is fixedly connected to one end of bidirectional screw 9. The bidirectional screw 9 adopts trapezoidal thread and uses the design that the thread helix angle is smaller than the friction angle of the thread pair to make the friction torque generated between the thread surfaces greater than the axial load torque it bears, forming mechanical self-locking, ensuring that the first moving seat 8 and inclined seat 7 remain stable in position when there is no external force driving.

[0024] By setting up support components, the sheet metal can be supported and subjected to friction. During the sheet metal transfer stage, the top of the support seat 2 (equipped with a rubber anti-slip pad) directly contacts the bottom of the sheet metal, providing uniform support. At the same time, the friction between the support seat 2 and the sheet metal prevents the sheet metal from sliding during the movement of the moving trolley 1, ensuring transfer safety. The height of the support seat 2 can be adjusted through the linkage structure of the bidirectional lead screw 9, the inclined seat 7, and the first moving seat 8: when the adjustment handle 17 drives the bidirectional lead screw 9 to rotate, the two sets of first moving seats 8 move in opposite directions or towards each other along the adjustment groove 16, driving the inclined seat 7 to move synchronously. The displacement mechanism utilizes the inclined plane's squeezing action to push the support seat 2 up and down along the guide rod 13. After the plate is raised to the loading height, the bidirectional lead screw 9 is adjusted in the opposite direction to disengage the inclined seat 7 from the support seat 2. The support seat 2 naturally falls under the action of the spring force 15 and the weight of the plate. At this time, the rotating roller 4, which was originally stored in the storage groove 3 of the support seat 2, gradually protrudes and contacts the bottom of the plate, converting the sliding friction during plate transfer into rolling friction. This significantly reduces the resistance of manually pushing the plate into the carriage, reducing the risk of surface wear on the plate and lowering the difficulty of operation for operators. Plate transfer can be completed without the need for multiple people to cooperate, significantly improving loading and unloading efficiency.

[0025] This utility model also includes a lifting assembly, which includes a vertical lead screw 10. A second movable seat 11 is mounted on the surface of the vertical lead screw 10. The second movable seat 11 is fixedly connected to one side of the mounting base 6. The vertical lead screw 10 is installed in a lifting groove 18 opened on one side of the column 22. The bottom of the column 22 is fixedly connected to the moving trolley 1. The second movable seat 11 is slidably engaged with the lifting groove 18. A lifting motor 19 is mounted on the top of the column 22. The output end of the lifting motor 19 is connected to the top of the vertical lead screw 10. In the transmission connection, two sets of support slide rods 20 are fixedly installed on both sides of the column 22. Support slide seats 21 are slidably installed on the surface of the support slide rods 20 and are fixedly connected to the mounting base 6. Among them, the lifting motor 19 has a built-in electromagnetic power failure brake. When the power is on, the brake pads separate without affecting the rotation of the bidirectional lead screw 9. After the power is cut off, the brake spring 15 pushes the brake pads to press the shaft of the lifting motor 19 and lock the shaft. This can achieve reliable positioning during vertical lifting and prevent the support components and plates from being accidentally displaced when stationary or under load.

[0026] The lifting assembly is the core structure for adjusting the vertical height of the sheet metal. First, the lifting assembly provides controllable vertical lifting power to the sheet metal through the transmission cooperation of the lifting motor 19, the vertical lead screw 10, and the second moving seat 11. After the lifting motor 19 starts, it drives the vertical lead screw 10 to rotate within the lifting groove 18. The second moving seat 11, due to its threaded engagement with the vertical lead screw 10 and its limitation by the lifting groove 18, moves smoothly in the vertical direction, thereby synchronously lifting the fixed mounting base 6, the upper support assembly, and the sheet metal. Operators can adjust the speed of the lifting motor 19 via the controller to achieve precise control of the sheet metal height, accurately adapting to the loading requirements of different car heights and preventing sheet metal collisions due to height deviations. Second, the support slides 20 on both sides of the column 22 and the support slides 21 form an auxiliary support structure. When the mounting base 6 moves with the second moving seat 11... During lifting, the support slide 21 slides synchronously along the support slide rod 20, effectively dispersing the radial load borne by the vertical lead screw 10 and preventing the mounting base 6 from tilting or swaying due to unilateral force. This ensures that the plate remains horizontal during lifting, especially for large plates, avoiding the risk of tipping due to center of gravity shift. Finally, the electromagnetic power-off brake built into the lifting motor 19 and the mechanical characteristics of the vertical lead screw 10 form a double safety lock: when powered on, the brake is released without affecting the rotation of the vertical lead screw 10; when powered off, the brake automatically locks the motor shaft, which, together with the thread self-locking of the vertical lead screw 10, prevents the second moving seat 11, the mounting base 6, and the plate from accidentally sliding down due to gravity. Even in the event of a power outage or sudden failure, the plate can still be kept stable at the specified height, completely eliminating safety hazards during loading and unloading and ensuring the safety of personnel and the plate.

[0027] This utility model also includes a controller for controlling the lifting motor 19. The core structure of the controller can be summarized as "four major functional modules + basic connection unit": the core includes a power module (built-in or external power interface, providing stable voltage for the controller and lifting motor 19, including overload protection elements to prevent circuit damage), a control chip module (such as a microcontroller or microprocessor, acting as the "command center", receiving operation signals and outputting motor start / stop and speed adjustment commands), a signal input module (connecting external operation buttons / knobs, converting manual control intentions into electrical signals and transmitting them to the control chip), and a drive module (receiving commands from the control chip, amplifying the current to drive the lifting motor 19 to operate as required, and adapting to the motor power); in addition, it also includes a basic connection unit (such as wiring terminals and circuit boards, realizing the circuit connection between modules and between the controller and the lifting motor 19, some of which include indicator light modules to display the power supply and motor working status). The overall structure is compact, with the core objective of achieving precise and safe control of the lifting components.

[0028] In practical use, the device is moved to the designated position, and the operator places the plate to be loaded / unloaded stably on top of the support base 2. At this time, the top of the support base 2 is in direct contact with the bottom of the plate. The friction and uniform support force of the support base 2 surface ensure that the plate will not slip during subsequent movement. Then, according to actual needs, the moving trolley 1 is pushed. While controlling the movement of the moving trolley 1, the operator holds the plate to maintain its stability and transfers the plate to the loading / unloading position next to the carriage. After reaching the target position, the lifting motor 19 is started by the controller. The lifting motor 19 drives the vertical lead screw 10 to rotate in the lifting groove 18, causing the second moving base 11, which cooperates with the vertical lead screw 10, to rise vertically along the lifting groove 18. At the same time, the mounting base 6 fixed to the second moving base 11, the support components above it, and the plate rise synchronously. The operator can adjust the speed of the lifting motor 19 through the controller to precisely control the lifting height of the plate until the bottom of the plate is inside the carriage. The height is aligned; once the board reaches the specified height, the adjustment handle 17 at the bottom of the mounting base 6 is rotated, driving the bidirectional lead screw 9 to rotate within the adjustment groove 16. This causes the two sets of first moving seats 8 to move in opposite directions along the adjustment groove 16, simultaneously separating the inclined seat 7. Under the elastic force of the spring 15, the support seat 2 falls naturally along the guide rod 13. The rotating roller 4, originally stored in the storage groove 3 of the support seat 2, gradually protrudes and contacts the bottom of the board. At this point, the board is pushed, and the rotating roller 4 converts the sliding friction between the board and the support seat 2 into rolling friction. The operator only needs a small pushing force to smoothly push the board into the carriage. After the board is transferred, the adjustment handle 17 is rotated in the opposite direction, causing the bidirectional lead screw 9 to drive the first moving seat 8 and the inclined seat 7 to move towards each other. The inclined surface of the inclined seat 7 presses against the bottom of the support seat 2, pushing the support seat 2 to rise and reset along the guide rod 13. The rotating roller 4 is then stored back in the storage groove 3, completing a complete board loading and unloading operation.
