An adjustable material handling robot

Abstract

This invention relates to the field of material handling technology, and specifically discloses an adjustable material handling robot. A drive component is fixedly connected to the side of the base, and the output end of the drive component is fixedly connected to the bottom of a sliding seat. A sliding seat is slidably connected to the inner side of the base, and a movable frame is fixedly connected to the top of the sliding seat. When a workpiece tends to slide downwards under external force or gravity, relative sliding friction is generated between the workpiece and the track. This friction drives the driven wheel of the track to rotate synchronously. A speed sensor on the transmission base starts monitoring, capturing the downward speed signal of the workpiece in real time, and dynamically adjusting the output speed of the drive component accordingly. This controls the positive rotation of the drive wheel, driving the track to move upwards at a speed exactly the same as the downward speed of the workpiece, forming a relatively stationary state where the track moves upwards and the workpiece moves downwards, thus counteracting the downward displacement of the workpiece.

Description

Technical Field

[0001] This invention relates to the field of material handling technology, specifically to an adjustable material handling robot. Background Technology

[0002] Material handling robots are intelligent devices based on automation control technology, specifically designed for material gripping, handling, stacking, and relocation operations in manufacturing, warehousing and logistics, and building materials processing. Their core features include adjustable gripping range, handling stroke, and gripping force, allowing for flexible adaptation to materials of different weights and shapes. Equipped with a PLC control system, they support manual, semi-automatic, and fully automatic operating modes. Driven by servo motors and utilizing precision guide rails and ball screws, they are equipped with multiple safety devices such as emergency stop buttons, infrared sensor protection, and overload protection. Through core logic of sensing, adjustment, and execution, they complete the entire process. During use, material parameters must be pre-matched, and obstacles within the operating range must be avoided. They effectively replace manual labor in high-intensity, repetitive handling tasks, improving operational efficiency and safety, and reducing enterprise labor and management costs. They are one of the core pieces of equipment in intelligent production and warehousing processes.

[0003] Chinese patent CN222511804U discloses an automated handling robot, including a control base. A robotic arm is mounted on the top of the control base, and a control arm is mounted on the bottom of the robotic arm. A control mechanism is located in the inner cavity of the bottom of the control arm, and a robotic claw is mounted on the bottom of the control arm. An adjustment groove is formed through one end of the robotic claw, and an adjustment plate is located in the inner cavity of the adjustment groove. Before handling materials, this automated handling robot can adjust the extension of the adjustment plate in the adjustment groove by activating an electric push rod between two fixed plates according to the size of the materials. This adjusts the range of material size that the robotic claw can grasp. With the help of the control mechanism and a buffer anti-slip pad, the material can be handled stably and with buffer, solving the problem that existing handling robots cannot adjust the grasping range of the robotic claw according to the material conditions. While this solution can effectively adjust and clamp the goods for stable handling, it is prone to causing goods with smooth sides to slide downwards due to external forces or gravity, which can lead to the goods falling off.

[0005] This invention provides an adjustable material handling robot. It has the following advantages: 1. When the workpiece tends to slide downwards under the action of external force or gravity, the contact surface between the workpiece and the track will generate relative sliding friction. This friction can drive the driven wheel of the track to rotate synchronously. The speed sensor on the transmission seat starts to monitor and capture the downward speed signal of the workpiece in real time. Based on this, the output speed of the drive component three is dynamically adjusted, thereby controlling the drive wheel to rotate in the forward direction and driving the track to move upward at a speed that is exactly the same as the downward speed of the workpiece. This forms a relatively stationary state where the track moves upward and the workpiece moves downward, thus counteracting the downward displacement of the workpiece.

[0006] 2. This adjustable material handling robot simultaneously activates the collection mechanism during the cleaning process, which can promptly collect impurities that fall off the contact mechanism, preventing them from scattering and falling onto the gripper surface. This achieves pre-treatment cleaning of the track gripping surface, preventing impurities from affecting the fit accuracy between the gripper and the goods, avoiding gripping slippage caused by impurities, and maintaining a clean working environment.

[0007] 3. This adjustable material handling robot uses the elastic support of springs to adapt to small position fluctuations during track operation, ensuring stable and uniform contact pressure between the cleaning roller and the track side. This removes dust, debris, and other impurities adhering to the track surface, preventing impurities from causing a decrease in the contact gap or friction coefficient when the track contacts the workpiece, thus ensuring the fit accuracy and anti-slip effect between the track and the workpiece.

[0008] 4. This adjustable material handling robot uses an airflow-driven spiral blade to rotate a rotating shaft between the inside of the collection cylinder and the baffle. This, in turn, causes a cleaning plate fixed on the rotating shaft to rotate synchronously against the surface of the baffle. The contact and rotation of the cleaning plate and the baffle can remove impurities attached to the surface of the baffle in real time, preventing impurities from accumulating and blocking the airflow channel, ensuring stable suction of the suction machine, ensuring impurity collection efficiency, and preventing impurities from hardening on the surface of the baffle, thus reducing the frequency and difficulty of subsequent manual cleaning.

[0009] 5. This adjustable material handling robot retracts its protective bar during clamping operations, completely avoiding the risk of interference with the clamping frame and goods, and improving the stability and success rate of clamping operations; when goods are being transported, the protective bar automatically unfolds to support the bottom, avoiding the risk of goods falling and ensuring the safety of the handling process.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Example 1, please refer to Figures 1-2 The present invention provides a technical solution: an adjustable material handling robot, comprising: A base 1 has a drive component 2 fixedly connected to its side. The output end of the drive component 2 is fixedly connected to the bottom of the sliding seat 3. The sliding seat 3 is slidably connected to the inside of the base 1. A movable frame 4 is fixedly connected to the top of the sliding seat 3. A drive component 6 is fixedly connected to the top of the movable frame 4. A lead screw 7 is rotatably connected to the inside of the movable frame 4. The output end of the drive component 6 is fixedly connected to the top of the lead screw 7. A protective component 8 is fixedly connected to the inside of the movable frame 4. Clamping component 5 is used for material handling. The side of clamping component 5 is slidably connected to the inside of the movable frame 4. Please see Figures 3-4The clamping component 5 includes an adjusting block 51, the side of which is slidably connected to the inner side of the moving frame 4, and the inner side of the adjusting block 51 is threadedly connected to the side of the lead screw 7. An adjusting seat 52 is fixedly connected to the side of the adjusting block 51, and a lead screw 53 is rotatably connected to the inner side of the adjusting seat 52. A driving component 54 is fixedly connected to the side of the adjusting seat 52, and the output end of the driving component 54 is fixedly connected to one end of the lead screw 53. Clamping frames 55 are symmetrically arranged on the inner side of the adjusting seat 52, and the top of the clamping frame 55 slides against the inner side of the adjusting seat 52. The clamping frame 55 is threaded to the side of the lead screw 53. A bracket 59 is fixedly connected to the inside of the clamping frame 55. A transmission seat 56 is fixedly connected to the other side of the bracket 59. A speed sensor is fixedly connected to the side of the transmission seat 56. A track 510 is rotatably connected to the side of the transmission seat 56. A drive component 511 is fixedly connected to the side of the transmission seat 56. A contact mechanism 58 is fixedly connected to the side of the bracket 59 near the track 510. A collection mechanism 57 is fixedly connected to the side of the clamping frame 55 away from the bracket 59. When clamping goods, the second drive unit 54 is activated, and its output end drives the second lead screw 53 to rotate inside the adjusting seat 52. Since the inner sides of the two clamping frames 55 are respectively adapted to the positive and negative threads of the second lead screw 53, the rotation of the second lead screw 53 can drive the two clamping frames 55 to move synchronously relative to each other, thereby closely fitting with the surface of the goods and completing the stable clamping of the goods. When the workpiece tends to slide downwards under the action of external force or gravity, the contact surface between the workpiece and the track 510 will generate relative sliding friction, which can drive the driven wheel of the track 510 to rotate synchronously. At this time, the speed sensor on the transmission seat 56 starts monitoring, capturing the downward speed signal of the workpiece in real time, and dynamically adjusting the output speed of the drive component 511 accordingly, thereby controlling the drive wheel to rotate in the forward direction, driving the track 510 to move upward at a speed completely consistent with the downward speed of the workpiece, forming a relatively stationary state where the track 510 moves upward and the workpiece moves downward, thus counteracting the downward displacement of the workpiece. Meanwhile, the contact surface between the track 510 and the workpiece is pre-designed with anti-slip texture, which can increase the micro-contact area between the two and improve static friction. The synchronous movement of the track 510 and the workpiece is achieved through speed closed-loop control. Static friction is used to replace sliding friction to prevent the workpiece from slipping. The anti-slip texture design further improves the friction coefficient and ensures anti-slip reliability under heavy load and high speed conditions. Before clamping the workpiece, the drive unit 511 can be turned on in advance. Its output end drives the track 510 to rotate at low speed in the adjusting seat 52 through the drive wheel. At the same time, the contact mechanism 58 continuously contacts and moves relative to the side of the track 510 to scrape and clean the impurities attached to the side of the track 510. During the cleaning process, the collection mechanism 57 is activated simultaneously to collect the impurities that have fallen off the contact mechanism 58 in a timely manner, preventing the impurities from scattering and falling onto the surface of the clamping frame 55. Please see Figure 5 The contact mechanism 58 includes a contact frame 581. The side of the contact frame 581 is fixedly connected to the middle of the inner side of the bracket 59. A mesh plate 582 is fixedly connected to the inner side of the contact frame 581. A slide rod 583 is slidably connected to both sides of the mesh plate 582 near the track 510. A support frame 584 is fixedly connected to the other end of the slide rod 583. A cleaning roller 585 is rotatably connected between the two support frames 584. A connecting spring 586 is sleeved on the slide rod 583. One end of the connecting spring 586 is fixedly connected to the mesh plate 582, and the other end of the connecting spring 586 is fixedly connected to the side of the support frame 584. During the rotation of the track 510 within the adjusting seat 52, the cleaning roller 585 is driven by the bracket 59 and the slide bar 583 to follow the movement. At the same time, the connecting spring 586 sleeved on the slide bar 583 provides continuous elastic support, so that the cleaning roller 585 can always be in close contact with the side of the track 510 and complete the scraping and cleaning operation as the track 510 rotates, thus preventing impurities from adhering to the side of the track 510. Please see Figure 6 The collection mechanism 57 includes a collection cylinder 571, which is fixedly connected to the side of the clamping frame 55 via a mounting bracket. Connecting pipes 572 are fixedly connected to both sides of the top of the collection cylinder 571. The other end of the connecting pipes 572 is fixedly connected to the inner side of the contact frame 581. An air suction machine 573 is fixedly connected to the inner side of the collection cylinder 571. A baffle 574 is fixedly connected to one side of the air suction machine 573. A cleaning assembly 575 is rotatably connected between the inner side of the collection cylinder 571 and the baffle 574. When the cleaning roller 585 is cleaning the side of the track 510, the suction machine 573 is turned on. The negative pressure suction generated by its operation is transmitted to the inside of the contact frame 581 through the connecting pipe 572. The impurities on the surface of the track 510 scraped off by the cleaning roller 585 are sucked in through the screen plate 582 and collected into the collection cylinder 571. At the same time, the airflow generated by the suction machine 573 can drive the cleaning component 575 inside the collection cylinder 571 to rotate synchronously. The rotating cleaning component 575 can continuously scrape and clean the side of the baffle 574 inside the cylinder, preventing dust and impurities entering the collection cylinder 571 from adhering to the surface of the baffle 574. Please see Figure 7The cleaning assembly 575 includes a spiral blade 5751. One end of the spiral blade 5751 is rotatably connected to the inner side of the collection cylinder 571. The other end of the spiral blade 5751 is fixedly connected to a rotating shaft 5752. Cleaning plates 5753 are fixedly connected to both sides of the rotating shaft 5752. The end of the rotating shaft 5752 away from the spiral blade 5751 is rotatably connected to the end of the baffle 574 away from the inhaler 573. The cleaning plate 5753 is in contact with the side of the baffle 574. After the inhaler 573 is started and running, the negative pressure suction it generates drives the airflow. The airflow drives the spiral blade 5751 to drive the rotating shaft 5752 to rotate between the inside of the collection cylinder 571 and the baffle 574. This in turn drives the cleaning plate 5753 fixed on the rotating shaft 5752 to rotate synchronously against the surface of the baffle 574, continuously scraping and cleaning the side of the baffle 574 to prevent impurities entering the collection cylinder 571 from adhering to the surface of the baffle 574 with the airflow. Example 2, please refer to Figures 8-9 Based on Embodiment 1, the present invention provides a technical solution: The protective component 8 includes a sliding block 81, which is slidably connected to the side of the movable frame 4. A sliding sleeve 82 is fixedly connected to the middle of the side of the sliding block 81. The inner side of the sliding sleeve 82 is slidably connected to the side of the lead screw 7. The side of the sliding sleeve 82 is slidably connected to the inner side of the movable frame 4. A connecting shaft 85 is fixedly connected to the bottom of the sliding sleeve 82. A connecting block 86 is fixedly connected to the bottom of the connecting shaft 85. The connecting block 86 and the connecting ring 87 are both concentrically arranged with the lead screw 7. A connecting ring 87 is fixedly connected to the middle of the side of the connecting shaft 85. A limit mechanism 88 is slidably connected to the side of the connecting shaft 85. A protective rod 83 is rotatably connected to the inner side of the sliding block 81. A connecting rod 84 is rotatably connected to the side of the protective rod 83. When the output end of the drive component 6 drives the lead screw 7 to rotate inside the moving frame 4, the sliding sleeve 82 moves downward synchronously with the adjusting block 51 because the thread direction of the sliding sleeve 82 is consistent with that of the adjusting block 51. Driven by the lead screw, the sliding sleeve 82 moves down synchronously along the inner side of the moving frame 4, and drives the connecting ring 87 and the connecting block 86 to move down synchronously through the connecting shaft 85, thereby causing the limiting mechanism 88 to move up along the side of the connecting shaft 85. The limiting mechanism 88 then drives the protective rod 83 to rotate inside the sliding block 81 through the connecting rod 84, thus completing the storage action of the protective rod 83. Please see Figure 10The limiting mechanism 88 includes a limiting cylinder 881 and two racks 883. The limiting cylinder 881 is concentrically arranged with the lead screw 7. The side of the limiting cylinder 881 is slidably connected to the side of the connecting shaft 85. The sides of the two racks 883 are fixedly connected to the inner side of the connecting block 86. Gears 882 are rotatably connected to both sides of the limiting cylinder 881. The side of the gears 882 is meshed with the inner side of the racks 883. The middle part of the limiting cylinder 881 is rotatably connected to the end of the connecting rod 84 away from the protective rod 83. When the sliding sleeve 82 moves down synchronously along the inner side of the movable frame 4, it drives the connecting ring 87 and the connecting block 86 to move down synchronously through the connecting shaft 85. At the same time as the connecting block 86 moves down, it drives the two racks 883 to move down synchronously along the limiting cylinder 881. With the meshing transmission of rack 883 and gear 882, the limiting cylinder 881 is driven to move upward along the side of the connecting shaft 85, and then the protective rod 83 is pulled by the connecting rod 84 to deflect inside the sliding block 81 and complete the storage, so as to avoid interference with the cargo clamping operation of the clamping frame 55. After the cargo clamping operation is completed, the output end of the drive component 6 drives the lead screw 7 to rotate in the opposite direction inside the moving frame 4. The sliding sleeve 82 moves upward synchronously with the adjusting block 51, and drives the connecting ring 87 and the connecting block 86 to move upward synchronously through the connecting shaft 85. When the connecting block 86 moves upward, it simultaneously drives the two racks 883 to move upward along the limiting cylinder 881. Through the meshing transmission of the racks 883 and the gears 882, the limiting cylinder 881 moves downward along the side of the connecting shaft 85. Then, through the connecting rod 84, it pushes the protective rod 83 to rotate inside the sliding block 81 until the protective rod 83 moves to the bottom of the goods, forming a bottom support.

[0014] Specific workflow: After the drive unit 6 is turned on by the control device, its output end drives the lead screw 7 to rotate inside the moving frame 4, thereby driving the clamping component 5 to move up and down along the moving frame 4 to complete the clamping and lifting action of the material. After the clamping component 5 clamps the material, the drive component 2 is started. Its output end drives the moving seat to move horizontally along the base 1 through the sliding seat 3, so as to realize the material position adjustment and handling operation. Meanwhile, during the entire material handling and movement process, the protective component 8 can provide bottom protection for the material on the clamping component 5.

[0015] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
