Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a rapid positioning mechanism for linear manipulators. Background Art

[0002] With the rapid development of industrial automation and intelligent manufacturing technology, robots have become one of the indispensable equipment in modern industrial production. Robots are commonly used in various automated production lines, assembly lines and logistics systems, and can replace humans to complete highly repetitive and dangerous tasks such as handling, welding, spraying and assembly. Therefore, the application of robots not only improves production efficiency, but also greatly reduces labor costs and safety risks in the production process. Linear robots are a type of robot that moves linearly along a fixed track or guide rail. They are widely used in scenarios that require high-precision positioning and repetitive operations. In practical applications, the positioning speed and accuracy of linear robots are crucial to the performance of the entire automation system. Therefore, rapid positioning mechanisms have become a key component in the design of linear robots. Traditional linear robot rapid positioning mechanisms usually rely on a combination of mechanical components such as screws and gear transmissions, and are driven by motors to achieve robot positioning. However, these mechanisms may suffer from problems such as slow positioning and poor positioning accuracy during long-term operation. Existing robot positioning frames (Announcement No.: CN218313542U) have at least the following shortcomings in use:

[0003] 1. The existing manipulator positioning mechanism has the problems of slow positioning speed and low accuracy. This is mainly due to the limitations of traditional mechanical structure design. For example, it relies on mechanical components such as screws or gear transmissions, which lead to friction and wear during the positioning process, thereby causing a decrease in accuracy. In addition, due to the lack of efficient sensors and control systems, the positioning response time is long, which makes it difficult to meet the needs of high-precision and high-speed industrial applications. These shortcomings make it difficult for existing manipulators to achieve fast and stable positioning when facing complex operation tasks, affecting the overall work efficiency and production quality. Therefore, there is an urgent need for a fast and accurate manipulator positioning mechanism.

[0004] 2. Existing manipulator positioning mechanisms usually lack adjustable support leg designs, which leads to poor adaptability in different working environments. Since the support legs cannot be adjusted in height or angle, the manipulator may have problems such as uneven working surface and equipment height mismatch during installation, which in turn affects the stability and positioning accuracy of the overall structure. In addition, the unadjustable support legs also limit the flexibility of the manipulator, making it difficult to adapt to diverse application scenarios, increasing environmental requirements, and reducing the versatility and practicality of the equipment. This shortcoming may lead to inaccurate positioning and unstable operation in actual operation, ultimately affecting production efficiency and operational safety. Therefore, there is an urgent need for a manipulator positioning mechanism with adjustable support legs.

[0005] 3. The existing robot positioning mechanism generally has the problem of poor stability, which is mainly reflected in the phenomenon of vibration and offset when working for a long time or in a complex environment. Due to the limitations of the mechanical structure design, such as the loose fit between the guide rail and the slider and the insufficient rigidity of the material, the robot is easily affected by external interference during rapid positioning, resulting in unstable motion path. In addition, the insufficient accuracy of the drive system or the lack of effective shock absorption measures also causes the robot to accumulate errors when performing precision tasks, making it difficult to maintain the stability of continuous operation. This poor stability not only affects the positioning accuracy, but may also shorten the life of the robot and increase maintenance and replacement costs. Therefore, a stable robot positioning mechanism is urgently needed. Utility Model Content

[0006] The main purpose of the utility model is to provide a rapid positioning mechanism for a linear manipulator, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A rapid positioning mechanism for a linear manipulator includes a lifting cylinder, an infrared sensor is installed on the right side of the lifting cylinder, a positioning plate is installed on the right side of the infrared sensor, a lead screw is installed below the positioning plate, a magnetic sheet is installed behind the positioning plate, a fixed sleeve is installed below the lifting cylinder, a grabbing cylinder is installed below the fixed sleeve, a grabber is installed below the grabbing cylinder, support legs are installed on both sides of the grabber, a first motor is installed on the right side of the positioning plate, and a second motor is installed below the first motor.

[0009] Preferably, a relative sliding fit is used between the lead screw and the positioning plate.

[0010] Preferably, a circular positioning hole is provided on the surface of the positioning plate.

[0011] Preferably, the connection between the gripper and the support leg is achieved through a bidirectional rotation joint.

[0012] Preferably, the gripper is fixedly connected to the gripping cylinder via the supporting legs.

[0013] Preferably, the support legs are fixed below the grabbing cylinder via vertical guide grooves.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model achieves fast and high-precision positioning of the manipulator by cleverly combining magnetic sheets and infrared sensors. The infrared sensor can accurately sense the positioning holes on the positioning plate and provide real-time feedback of position information during movement to ensure positioning accuracy and stability. This design not only improves the positioning speed of the manipulator, but also greatly improves the positioning accuracy and reduces the errors caused by friction or wear in traditional mechanical structures. In addition, the coordinated use of infrared sensors and magnetic sheets enables the system to maintain a high degree of reliability and consistency in complex environments, ensuring long-term stable operation of the equipment and improving overall work efficiency.

[0016] 2. The utility model is innovatively equipped with an adjustable support leg design, which makes the manipulator more adaptable in various working environments. The support legs can not only slide left and right, but also stretch up and down, flexibly adjusting the working height and angle of the manipulator to ensure that it remains stable and precise under uneven or complex ground conditions. This design greatly enhances the flexibility of the manipulator, can easily adapt to different installation scenarios, and reduce positioning errors caused by uneven ground or mismatched equipment heights. In addition, the adjustable support legs can effectively disperse the load pressure, extend the service life of the manipulator, and improve overall work efficiency and safety.

[0017] 3. The utility model adopts a double-screw design, which greatly improves the stability of the manipulator compared to the traditional single-screw structure. The double-screw design disperses stress on the structure, reduces the vibration and swing of the manipulator under fast movement or heavy load conditions, and makes the movement of the manipulator more stable and precise. In addition, the double guide rails can effectively prevent positioning deviations caused by wear or deformation of a single guide rail, ensuring the consistency and reliability of the manipulator during long-term operation. This structural design not only extends the service life of the equipment, but also significantly improves the accuracy and efficiency of the operation, enabling the manipulator to maintain excellent performance in complex and harsh working environments.
