Description

Technical Field

[0001] This utility model relates to the technical field of machining, and in particular to the technical field of material transfer robots. Background Technology

[0002] Vacuum suction cup robots are widely used in various industries as flexible and efficient material handling devices. For example, in CNC lathes, vacuum suction cup robots can automatically handle fragile materials such as glass and sheets. However, the robot may vibrate during operation. This vibration may be caused by the precision of the mechanical structure itself, the unstable operation of the motor, or interference in the working environment (such as the presence of other heavy equipment operating nearby). These vibrations will be transmitted to the material held by the suction cup, causing a slight relative displacement between the suction cup and the material. If the vibration is continuous or large, it will disrupt the suction state of the suction cup, causing the material to fall off. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the existing technology by proposing a vacuum suction cup robot for preventing materials from falling, which can prevent materials from falling and ensure the safety of the robot in use.

[0004] To achieve the above objectives, this utility model proposes a vacuum suction cup robot for preventing material drop, comprising a robot body, a material handling component, a main frame, a lifting mechanism, a movable frame, suction cups, a servo motor, a rotating shaft, and a lifting plate. A material handling component is installed at the end of the robot body. The material handling component consists of the main frame, lifting mechanism, movable frame, suction cups, servo motor, rotating shaft, and lifting plate. The main frame is fixed to the end of the robot body. A movable frame is located below the main frame and is connected to a lifting mechanism mounted on the main frame. The lifting mechanism drives the movable frame to move vertically up and down. Several suction cups are installed at the bottom of the movable frame. Several servo motors are installed on the main frame and are connected to the rotating shaft. The rotating shaft is vertically positioned and distributed around the movable frame. A lifting plate is fixed to the side of the rotating shaft furthest from the movable frame.

[0005] Preferably, when the lifting mechanism moves the movable frame to its highest position, the lifting plate is located below the suction cup; when the lifting mechanism moves the movable frame to its lowest position, the lifting plate is located above the suction cup; and the servo motor drives the rotating shaft to rotate 180° each time.

[0006] Preferably, the lifting mechanism consists of a cylinder, a connecting frame, a guide rod, and a guide sleeve. The cylinder is fixedly installed on the main frame and is vertically upward. The top of the piston rod of the cylinder is connected to the connecting frame. The connecting frame is located above the movable frame. The connecting frame and the movable frame are connected by several vertically arranged guide rods. The guide rods are fitted with guide sleeves, which are fixedly installed on the main frame.

[0007] Preferably, a bearing is fitted around the rotating shaft, and the bearing is fixedly mounted on the main frame. A transmission head is fixed at the end of the output shaft of the servo motor. A transmission groove that mates with the transmission head is provided at the top of the rotating shaft. The transmission head is inserted into the transmission groove, and there is a gap between the transmission head and the bottom of the transmission groove.

[0008] The beneficial effects of this utility model are as follows: By setting the suction cup on a liftable movable frame and the lifting plate on a rotating shaft driven by a servo motor, multiple lifting plates can be set below the material after it is sucked up, so that the material will not fall completely even if it detaches from the suction cup during the transfer process, thus ensuring the safety of the robot.

[0009] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0013] See Figure 1 , Figure 2 This utility model relates to a vacuum suction cup robotic arm for preventing material drop, comprising a robotic arm body 1, a material handling component 10, a main frame 2, a lifting mechanism 3, a movable frame 4, suction cups 40, a servo motor 50, a rotating shaft 5, and a lifting plate 51. The material handling component 10 is installed at the end of the robotic arm body 1. The material handling component 10 consists of the main frame 2, the lifting mechanism 3, the movable frame 4, the suction cups 40, the servo motor 50, the rotating shaft 5, and the lifting plate 51. The main frame 2 is fixed to the end of the robotic arm body 1. A movable frame 4 is located below the main frame 2. The movable frame 4 is connected to a lifting mechanism 3 installed on the main frame 2. The lifting mechanism 3 drives the movable frame 4 to move vertically up and down. Several suction cups 40 are installed at the bottom of the movable frame 4. Several servo motors 50 are installed on the main frame 2. The servo motors 50 are connected to the rotating shaft 5, which is vertically arranged and distributed around the movable frame 4. A lifting plate 51 is fixed to the side of the rotating shaft 5 away from the movable frame 4.

[0014] When the lifting mechanism 3 moves the movable frame 4 to its highest position, the lifting plate 51 is located below the suction cup 40. When the lifting mechanism 3 moves the movable frame 4 to its lowest position, the lifting plate 51 is located above the suction cup 40. The servo motor 50 drives the rotating shaft 5 to rotate 180° each time.

[0015] To improve the stability of the movable frame 4 during lifting, the lifting mechanism 3 consists of a cylinder 31, a connecting frame 32, a guide rod 33, and a guide sleeve 34. The cylinder 31 is fixedly installed on the main frame 2 and is vertically upward. The top of the piston rod of the cylinder 31 is connected to the connecting frame 32, which is located above the movable frame 4. The connecting frame 32 and the movable frame 4 are connected by several vertically arranged guide rods 33. The guide rods 33 are fitted with guide sleeves 34, which are fixedly installed on the main frame 2.

[0016] To prevent the output shaft of the servo motor 50 from being subjected to excessive axial force, a bearing 52 is fitted on the outside of the rotating shaft 5. The bearing 52 is fixedly mounted on the main frame 2. A transmission head 55 is fixed at the end of the output shaft of the servo motor 50. A transmission groove 56 that cooperates with the transmission head 55 is provided at the top of the rotating shaft 5. The transmission head 55 is inserted into the transmission groove 56, and there is a gap between the transmission head 55 and the bottom of the transmission groove 56.

[0017] The working process of this utility model:

[0018] In operation, this novel anti-drop material transfer vacuum suction cup robot is suitable for transferring plate-shaped materials. Initially, the movable frame 4 is at its lowest position. The robot body 1 moves the material-picking component 10 to the picking position, where the suction cup 40 picks up the material. Then, the lifting mechanism 3 moves the movable frame 4 upwards, and the material moves upwards as well. The lifting mechanism 3 moves the material until its bottom surface is 0.5mm-2mm higher than the top surface of the lifting plate 51. The servo motor 50 drives the rotating shaft 5 to rotate 180°, at which point the lifting plate 51 is below the material. Then, the robot body 1 moves the material-picking component 10, along with the material picked up by the component 10, to the discharging position. The servo motor 50 then drives the rotating shaft 5 to rotate 180°, and the lifting mechanism 3 moves the movable frame 4 to its lowest position. Finally, the suction cup 40 releases the material.

[0019] During material movement, since the lifting plate 51 is located below the material, when the material separates from the suction cup 40 for various reasons, the material can be supported by the lifting plate 51 and will not fall, thus ensuring the safety of the robot.

[0020] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
