Description

Technical Field

[0001] This utility model relates to the field of industrial automation and intelligent manufacturing equipment technology, specifically to an intelligent mechanical automatic loading and unloading device. Background Technology

[0002] In modern industrial production, the level of automation and intelligence in material handling directly affects production efficiency, product quality, and operational safety. Traditional manual loading and unloading methods suffer from high labor intensity, low efficiency, and poor precision, making them unsuitable for large-scale manufacturing and flexible production. Therefore, automated mechanical loading and unloading devices have gradually become key equipment in the field of industrial automation, and their technological development has evolved from single-function to multi-axis linkage, and from open-loop control to intelligent closed-loop control.

[0003] Traditional robotic arms rely on open-loop control or single-point sensor feedback, which are prone to positioning errors due to mechanical backlash and inertial impact, making them unsuitable for precision machining. Suction cup devices, when grasping flexible materials, are prone to material slippage or deformation due to vacuum fluctuations or uneven suction surfaces. Most devices are equipped with only a single actuator (such as a robotic arm or a suction cup alone), unable to simultaneously adapt to the grasping needs of both rigid and flexible materials. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent automatic loading and unloading device for machinery to solve the problems mentioned in the background art.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Reference Figure 1 and Figure 2An intelligent automatic loading and unloading device includes a base frame 1. A slide rail 2 is fixedly mounted on the upper side of the base frame 1, and a slide block 3 is slidably mounted on the slide rail 2. A sliding screw 4 is rotatably mounted on the upper side of the base frame 1 and on one side of the slide block 3. The slide block 3 is connected to the sliding screw 4 via a sliding sleeve 5. A sliding motor 6 is fixedly mounted on the upper side of the base frame 1, and the sliding motor 6 is drivenly connected to the sliding screw 4. A first sleeve 7 and a second sleeve 8 are rotatably mounted on the upper side of the slide block 3. A first screw 9 is mounted inside the first sleeve 7. A first fixing plate 10 is fixedly mounted on the upper end of the first screw 9, and a first guide rod 11 is fixedly mounted on the lower side of the first fixing plate 10. A guide rod 11 is slidably connected to the slide block 3 and its lower end extends to the lower side of the base frame 1. A robot arm 12 is fixedly connected to the lower end of the first guide rod 11. A second lead screw 13 is provided inside the second threaded sleeve 8. A second fixing plate 14 is fixedly provided at the upper end of the second lead screw 13. A second guide rod 15 is fixedly provided at the lower side of the second fixing plate 14. The second guide rod 15 is slidably connected to the slide block 3 and its lower end extends to the lower side of the base frame 1. A suction cup 16 is fixedly connected to the lower end of the second guide rod 15. A first motor 17 and a second motor 18 are fixedly provided at the lower side of the slide block 3. The first motor 17 and the second motor 18 are respectively connected to the first threaded sleeve 7 and the second threaded sleeve 8 for transmission.

[0020] A position sensor 19 is provided on the upper side of the base frame 1 and on one side of the slide rail 2. A position sensor 19 is also provided on the upper side of the base frame 1 and on one side of the first guide rod 11 and the second guide rod 15 respectively via the bracket 20.

[0021] The suction cup 16 is fixedly mounted at the lower end of the second guide rod 15 via the connecting frame 21. The connecting frame 21 is in the shape of a grid, and the suction cup 16 includes multiple suction cups that are evenly arranged on the lower side of the connecting frame 21.

[0022] There are two position sensors 19 corresponding to slide rail 2, first guide rod 11 and second guide rod 15.

[0023] It also includes a control system, with position sensor 19 electrically connected to the control system. The control system is based on a PLC and integrates functions such as position signal acquisition and logic judgment, motor drive control, vacuum generator start / stop control, and safety interlock protection.

[0024] This invention achieves automatic material gripping, movement, and placement through the coordinated operation of a precise mechanical structure and control system. The specific working principle is as follows:

[0025] Lateral movement:

[0026] The sliding motor 6 starts and drives the sliding screw 4 to rotate via the synchronous belt pulley.

[0027] The rotational motion of the sliding screw 4 is converted into the linear motion of the slide block 3 through the sliding sleeve 5, causing the slide block 3 to move laterally along the slide rail 2.

[0028] When the slide block 3 moves to the preset position, the position sensor 19 detects the signal and transmits it to the control system. The control system then controls the sliding motor 6 to stop, achieving precise lateral positioning.

[0029] Vertical lifting:

[0030] For the robotic arm: The first motor 17 starts, driving the first lead screw 7 to rotate. The rotational motion of the first lead screw 7 is converted into the lifting motion of the first fixed plate 10 through the first lead screw 9. The lifting of the first fixed plate 10 drives the first guide rod 11 and the robotic arm 12 to rise and fall, realizing the vertical movement of the robotic arm 12. When the robotic arm 12 moves to a preset height, the position sensor 19 detects a signal and transmits it to the control system, which then controls the first motor 17 to stop.

[0031] For the suction cup side: The second motor 18 starts, driving the second threaded sleeve 8 to rotate. The rotational motion of the second threaded sleeve 8 is converted into the lifting motion of the second fixed plate 14 through the second lead screw 13. The lifting of the second fixed plate 14 drives the second guide rod 15 and the suction cup 16 to rise and fall, realizing the vertical movement of the suction cup 16. When the suction cup 16 moves to the preset height, the position sensor 19 detects the signal and transmits it to the control system, which then controls the second motor 18 to stop.

[0032] Material picking and placing:

[0033] When the robotic arm 12 or the suction cup 16 moves above the material, the control system controls the robotic arm 12 to close or the suction cup 16 to create a vacuum to grab the material.

[0034] After grabbing the material, the control system controls the sliding motor 6 and the first motor 17 or the second motor 18 to start, moving the material above the target position.

[0035] When the material moves above the target position, the control system controls the robot arm 12 to open or the suction cup 16 to close the vacuum, releasing the material and completing the placement of the material.

[0036] Security protection:

[0037] The position sensor 19 is not only used for positioning, but also plays a safety protection role. When the slide 3, the robot arm 12, or the suction cup 16 moves to the limit position, the position sensor 19 detects the signal and transmits it to the control system. The control system immediately controls the corresponding motor to stop to prevent equipment damage or accidents.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
