Description

Technical Field

[0001] This utility model relates to a material handling robot, and more particularly to a material handling robot for machine tool processing. Background Technology

[0002] In machine tool processing, material handling is an important step. To reduce dangerous or repetitive processes and improve processing efficiency, robotic arms can replace manual operations.

[0003] The robotic arms used in machine tool processing reduce human involvement and interference in processing steps, reduce human error, save material waste caused by errors, and greatly improve the level of automation and production efficiency. However, in the production process, existing robotic arms have significant limitations. They are designed for specific processes or workpiece types, have poor versatility, and cannot serve multiple machine tools producing different workpieces at the same time. Once production needs change, for workpieces with changes in size, shape, and material, the robotic arm may need to frequently adjust or change the fixtures, affecting production efficiency. Utility Model Content

[0004] To overcome the limitations of existing robotic arms, which are designed for specific processes or workpiece types, have poor versatility, and cannot simultaneously serve machine tools producing multiple different workpieces, and whose fixtures may need frequent adjustments or replacements when production demands change for workpieces of different sizes, shapes, or materials, thus affecting production efficiency, the purpose of this invention is to provide a material handling robotic arm that can simultaneously install multiple different material handling fixtures, can be flexibly switched during use, has strong versatility, and can meet various processing needs.

[0005] The technical solution is as follows: A material handling robot for machine tool processing includes a truss, a transmission component one, a connecting seat, a lifting platform, a cylinder, a connecting turntable, a drive motor, a slide, a rack, a transmission component two, a clamping fixture one, and a clamping fixture two. The transmission component one is horizontally mounted on the upper part of the truss. A slider is mounted on the transmission component one. The connecting seat is fixedly mounted on the slider of the transmission component one. The lifting platform is slidably mounted on the connecting seat. An electric cylinder is installed inside the connecting seat. The extension rod of the electric cylinder is connected to the connecting seat. The lower part of the electric cylinder is fixedly connected to the lifting platform. The extension of the electric cylinder... When the retractor extends, the lifting platform slides downward. A connecting turntable is rotatably installed at the bottom of the lifting platform. A drive motor is installed on the upper inner side of the connecting turntable. The output shaft of the drive motor is fixedly connected to the lifting platform. A sliding seat is installed at the lower part of the connecting turntable. Racks are installed on both the left and right sides of the sliding seat. A transmission component two is installed on the lower inner side of the connecting turntable. The transmission component two consists of a dual-shaft motor and two gears. The two gears of the transmission component two mesh with the two racks respectively. Clamp two and clamp one are installed on the front and rear sides of the lower part of the sliding seat respectively.

[0006] As a further preferred option, it also includes anti-shake support rods, mounting brackets, and dampers. Anti-shake support rods are slidably provided on both sides of the connecting turntable, and mounting brackets are rotatably provided at both ends of the anti-shake support rods. Each mounting bracket is equipped with a damper, and the lower end of each damper is connected to a slide.

[0007] As a further preferred option, it also includes a fixed frame and a waiting platform. The fixed frame is installed on the upper rear side of the truss, and the waiting platform is horizontally set at the lower part of the fixed frame.

[0008] As a further preferred option, it also includes positioning grooves, with positioning grooves opened on both the left and right sides of the waiting platform.

[0009] As a further preferred option, it also includes a cross slide and a detector. A cross slide is installed on the fixed frame, and a detector is installed on the moving platform of the cross slide. The detector's detection probe faces the side of the waiting platform, and the detector moves left and right and up and down with the cross slide.

[0010] As a further preferred option, the transmission component and the electric cylinder operate at a uniform speed and smoothly.

[0011] This invention utilizes a robotic arm capable of mounting multiple different types of material handling fixtures. During material handling, the robotic arm can quickly switch between fixtures as needed. Compared to configuring multiple single-function robotic arms, a single robotic arm equipped with multiple fixtures can cover a wider range of task requirements, enhance the responsiveness of the production line, and provide greater flexibility. When processing various products, there is no need to frequently change fixtures, allowing for continuous processing of different types of workpieces, reducing downtime, and achieving efficient and flexible production.

[0012] This invention enhances the mechanical structure of the slide by installing anti-vibration support rods when the gripper of the robotic arm extends. At the same time, the damper installed at the end of the slide can effectively buffer and absorb the end vibration caused by the force during material gripping, avoiding structural damage and loss of material picking accuracy caused by the vibration of the robotic arm, and ensuring the normal operation of material picking and placing.

[0013] This invention features a material waiting platform that can detect the materials being picked up and placed, enabling timely inspection of workpieces before and after processing. This avoids batch problems caused by undetected processing flaws and reduces losses due to processing quality issues. Attached Figure Description

[0021] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0022] Example 1: A material handling robot for machine tool processing, such as Figure 1-5As shown, the structure includes a truss 1 formed by intersecting and welded members, which provides good support. A transmission component 2 is horizontally mounted on the upper part of the truss 1. The transmission component 2 consists of a frame, a lead screw, and a drive motor that drives the lead screw. A slider is mounted on the transmission component 2, and a connecting seat 3 is fixedly mounted on the slider. The connecting seat 3 moves left and right under the drive of the transmission component 2. A lifting platform 4 is slidably mounted on the connecting seat 3. A drive cylinder 41 is installed inside the connecting seat 3. The telescopic rod of the cylinder 41 is connected to the connecting seat 3, and the lower part of the cylinder 41 is fixedly connected to the lifting platform 4 via a connector. When the telescopic rod of the cylinder 41 extends, the lifting platform 4 slides downward. The cylinder 41 can precisely control the extension distance of the telescopic rod, thereby precisely controlling the lifting height of the lifting platform 4. A connecting turntable 42 is rotatably mounted at the bottom of the lifting platform 4. A drive motor 43 is installed on the upper inner side of the connecting turntable 42. The output shaft of the drive motor 43 is fixedly connected to the bottom of the lifting platform 4. When the drive motor 43 rotates, it will drive the connecting turntable 42 to rotate. The lower part of the connecting turntable 42 is provided with a sliding seat 5. The front and rear sides of the lower part of the sliding seat 5 are respectively equipped with clamp 2 53 and clamp 1 52. Clamp 1 52 and clamp 2 53 are used to pick up and put down workpieces of different types. The position of clamp 1 52 and clamp 2 53 on the sliding seat 5 can be switched by the drive motor 43. The left and right sides of the sliding seat 5 are equipped with racks 50. The lower inner side of the connecting turntable 42 is provided with a transmission component 2 51. The transmission component 2 51 consists of a dual-axis motor and two gears. The two gears of the transmission component 2 51 mesh with the two racks 50 respectively. When the dual-axis motor works, the racks 50 on both sides of the sliding seat 5 will move forward or backward under the drive of the gears on the transmission component 2 51, thereby driving the clamp 1 52 and clamp 2 53 on the sliding seat 5 to adjust their positions.

[0023] When a workpiece that needs to be processed by the machine tool is removed, the connecting seat 4 on the control transmission component 2 moves to the material-picking position of the machine tool. Then, the control drive motor rotates the connecting turntable 42 and the slide 5, adjusting the material-picking fixture to face the workpiece. The control electric cylinder 41 then raises and lowers the lifting platform 42, adjusting the material-picking height of the fixture. Next, the control transmission component 51 drives the slide 5 to extend towards the workpiece inside the machine tool, removing the workpiece from the machine tool using fixture 52 or fixture 53. The control robot then removes the material from the machine tool. Following the above material-picking actions, unprocessed external parts are then picked up and processed inside the machine tool. By using various types of fixtures, the material-picking fixture can be quickly switched as needed during machine tool processing, compared to configuring multiple fixtures... A single-function robotic arm can cover a wider range of task requirements, enhancing the responsiveness of the production line and providing greater flexibility. When processing multiple products, frequent fixture changes are unnecessary. During operation, the transmission component 2 and electric cylinder 41 operate at a uniform and stable speed, preventing vibration during transmission. The travel distance of the gantry 1 and transmission component 2 can be set as needed. This means that when the robotic arm can move over a long area, it can simultaneously handle multiple horizontally arranged machine tools. Depending on the different types of fixtures on the robotic arm, it can pick up different types of workpieces being processed on different machine tools. This reduces the number of robotic arms required, lowers costs, and facilitates centralized management and maintenance.

[0024] Example 2: Based on Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it also includes two anti-vibration support rods 6 that are slidably mounted on the connecting turntable 42. The anti-vibration support rods 6 are respectively located on the left and right sides of the lower part of the connecting turntable 42. They are made of a rigid material with a certain degree of toughness. Both ends of the anti-vibration support rods 6 are rotatably mounted with mounting brackets 61. Each mounting bracket 61 is equipped with a damper 62 to improve the working accuracy and stability. The anti-vibration support rods 6 move synchronously with the slide 5 under the action of the dampers. The lower end of each damper 62 is connected to the slide 5. The anti-vibration support rods 6 and dampers 62 absorb the vibration energy of the slide 5 during its movement, effectively reducing the vibration amplitude and impact of the mechanical structure. During the transition between rapid movement and emergency stop, the dynamic response characteristics of the robot are optimized, unnecessary motion lag or oscillation is reduced, and the overall working efficiency and accuracy are improved.

[0025] In a preferred embodiment: such as Figure 1 and Figure 6As shown, it also includes a fixed frame 7 installed on the upper rear side of the truss 1. A waiting platform 71 for temporary workpiece storage is horizontally set at the lower part of the fixed frame 7. The waiting platform 71 has a positioning groove 8 to facilitate the positioning of the workpiece when the robot arm places it, so as to facilitate the reasonable placement of the workpiece. By setting up the waiting platform 71 as a temporary storage area, workpieces or semi-finished products that are about to be put into the machine tool or taken out of the machine tool are placed, ensuring that the workpieces have a fixed placement position before formal use, and at the same time, it is convenient for the robot arm to pick up and put down the workpieces from the waiting platform 71, so as to ensure the continuous and smooth operation of the production line.

[0026] In a preferred embodiment: such as Figure 1 and Figure 6 As shown, it also includes a cross slide table 9 mounted on a fixed frame 7. The cross slide table 9 is equipped with a movable stage. The cross slide table 9 consists of two mutually perpendicular guide rails and a slider. The movable stage moves smoothly and is precisely positioned in two dimensions along the horizontal and vertical directions on the guide rails of the cross slide table 9. A detector 10 is mounted on the movable stage of the cross slide table 9. The detection probe of the detector 10 faces the waiting table 71. The detector 10 has preset appearance information of finished workpieces or formed workpieces in the corresponding workstation during production. The detector 10 moves left and right and up and down with the cross slide table 9 to perform detailed inspection of the workpieces temporarily placed on the waiting table 71 and to feed back the inspection results. Before the material is moved to the production line, the waiting table 71 provides a pre-inspection area and, in conjunction with the detector, performs appearance, quality or model inspection on the processed objects to prevent unqualified products from entering the production process.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
