[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0017] As shown in Figures 1-4 , a screw rod lifting type mechanical arm, including driving device and base part 1, still including lifting platform part 2 and mechanical arm part 3, lifting platform part 2 includes lifting platform 2-4, and screw nut 2-2 is installed on lifting platform 2-4, screw nut 2-2 is matched with lead screw 2-3, and shaft rod 2-1 is slidably arranged on lifting platform 2-4, mechanical arm part 3 includes holder 3-1, serial steering wheel 3-6 and gripper seat 3-2, gripper seat 3-2 is connected with mechanical arm, and serial steering wheel 3-6 drives mechanical arm to move. When the application is used, shaft rod 2-1 is fixed on the ground or support, and lifting platform is moved up and down along shaft rod by driving screw rod movement, and operation is stable and efficient.

[0018] Preferably, the mechanical arm includes a primary mechanical arm 3-3 and a secondary mechanical arm 3-4, and the secondary mechanical arm is driven by a steering engine. In this application, the mechanical arm is in a frame structure and is made of aluminum alloy material, which can reduce the weight and improve the stability of the mechanical claw. In this application, the operation of the gripper 3-5 is driven by a steering engine, and the secondary mechanical arm 3-4 is also driven by a separate steering engine, so that the secondary mechanical arm 3-4 can rotate around the primary mechanical arm 3-3, and the primary mechanical arm 3-3 is driven by a serial steering engine 3-6, so that the primary mechanical arm 3-3 rotates around the holder. Among them, the primary mechanical arm, the secondary mechanical arm and the gripper are respectively driven by different steering engines, so that the whole device runs more flexibly.

[0019] The lifting platform part is mainly composed of a lead screw, a lifting platform and a shaft 2-1. The lead screw nut 2-2 is installed on the lifting platform. The height of the lifting platform 2-4 is controlled by the forward and reverse rotation of the lead screw 2-3. The lead screw can bear radial and axial load, has high structural strength, long service life and other characteristics, and can use balls or rollers as rolling bodies to transfer larger load. The lead screw transmission generally has better dynamic performance, fast response speed and small dynamic friction.

[0020] Preferably, the base part 1 includes two pulleys and a synchronous belt, one of which is fixed at the bottom of the lead screw 2-3. The base part is composed of two pulleys and a transmission belt. According to different needs, different transmission ratios can be selected to achieve different lifting speeds. The synchronous belt can more accurately control the lifting position of the lifting platform, avoiding the sliding and slipping phenomenon in traditional belt transmission. Based on the design of the synchronous belt, the transmission efficiency is improved, the energy loss is reduced, and the mechanical transmission efficiency is improved. In addition, the synchronous belt has high stability and is not easily affected by external factors such as temperature change and humidity change, and has long service life, is not easy to wear and tear, and has low maintenance cost.

[0021] Preferably, the gripper seat 3-2 is provided with a camera. In this application, the mechanical arm part is composed of a holder, two-stage mechanical arm, gripper seat and gripper. The holder is fixed on the lifting platform, and the primary and secondary mechanical arms are installed on it. The angle of rotation of the steering engine is used to control the gripper 3-5 to reach the specified position. After reaching the specified position, the color and shape of the object are identified through the camera on the gripper seat, and the steering engine on the gripper seat is rotated to drive the gripper to realize the grabbing and placing of the object.

[0022] During use, the lead screw needs to be lubricated and replaced regularly to ensure smooth operation. The serial steering engine and synchronous belt are important components for driving the lead screw, and need regular inspection and maintenance to ensure the movement accuracy and stability of the robotic arm. It is necessary to maintain its smooth operation, avoid sudden stop and excessive movement, and prolong its service life. At the same time, regular maintenance and maintenance should be carried out. The application meets the needs of space utilization, safety and other aspects. As an automatic handling and assembly device, it plays an important role in modern industrial production, and provides reliable technical support for the intelligentization, high efficiency and safety of the production line.
