Description

Technical Field

[0001] This utility model relates to the field of parts gripping equipment technology, and in particular to a gripping mechanism for loading and unloading automotive parts. Background Technology

[0002] In the automotive manufacturing industry, the loading and unloading of parts is a key link in the production process. This step involves accurately moving various automotive parts from the storage area or previous process to the assembly line or processing equipment, and removing them after processing to prepare for the next operation or warehousing.

[0003] In the process of automobile manufacturing, automated loading and unloading equipment is typically used for loading and unloading parts. For example, Chinese utility model patent CN212245254U discloses a loading device for automobile parts production. This application includes a base plate, a chassis rotatably mounted on the top of the base plate, a track plate mounted on the top of the base plate, a lifting block slidably mounted on the track plate, a fixed block mounted on the lifting block, a swing rod hinged to the top of the track plate, a track hole on the swing rod, the track hole slidably connected to the inner wall of the fixed block, and one end of the swing rod hinged to… The device includes an adjusting rod, on which an adjusting cylinder is hinged. The piston rod of the adjusting cylinder is hinged to the adjusting rod. One end of the adjusting rod is fitted with an mounting plate, on which two movable blocks are slidably mounted. This structure allows the device to clamp parts of different sizes without manual handling, improving the safety of feeding and facilitating the adjustment of the part's position and orientation, thus enabling electric feeding. However, since the clamping end of this device consists of a mounting plate, movable blocks, a movable rod, a clamping plate, and an electric telescopic rod, the size range of the parts that this device can clamp is relatively small, and it cannot quickly adjust the clamping structure according to different shapes and structures of the parts. Utility Model Content

[0004] The purpose of this invention is to provide a gripping mechanism for loading and unloading automotive parts, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A gripping mechanism for loading and unloading automotive parts includes a main frame, with multiple support rods fixedly installed on both sides of the main frame, and a side rod fixedly connected between two of the support rods. Mounting seats are fixedly installed on both sides of the main frame and the side rods located between the two side rods. A transmission device is fixedly installed on one side of the mounting seat, and a transmission device is movably installed at the bottom of the transmission device. A cylinder is fixedly installed on the top of the transmission device, and the cylinder is connected to an external air pump through an air pipe.

[0007] As a further optimization of this utility model, a robot arm mounting flange is fixedly installed at the top center of the main frame, and the robot arm mounting flange is fixedly connected to the external robot arm.

[0008] Based on this, a robotic arm mounting flange is set on the main frame, which makes it easier for the entire gripping mechanism to be used with different models of robots.

[0009] As a further optimization of this utility model, a hanging rod is fixedly installed at the bottom of the side rod near the mounting base, and a proximity sensor is fixedly installed at the bottom of the hanging rod. The proximity sensor is electrically connected to an external main controller via a connecting wire.

[0010] Based on this, by using a proximity sensor, when the proximity sensor approaches the part, the cylinder is inflated and works in conjunction with the transmission and grippers to grasp the workpiece.

[0011] As a further optimization of this utility model, the input end of the transmission is movably connected to the output end of the cylinder, and a rotating frame is rotatably mounted on the output end of the transmission.

[0012] As a further optimization of this utility model, a gripper is fixedly installed on one side of the rotating frame, and the gripper is also located below the transmission device;

[0013] Based on this, a rotating frame is mounted on the outside of the transmission device, and a gripper is fixedly mounted on one side of the rotating frame. This allows the gripper to be flipped and opened in conjunction with a cylinder, thus facilitating the gripping of parts.

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

[0015] The present invention discloses a gripping mechanism for loading and unloading automotive parts. Multiple mounting seats are respectively arranged on the outer sides of the main frame and side rods. Cylinders are mounted on the mounting seats, and a transmission device is mounted below the mounting seats. A rotating frame is mounted at the output end of the transmission device, and a gripper is mounted on one side of the rotating frame. This allows for the gripping of parts of different sizes. Furthermore, the mounting position of the mounting seats can be easily adjusted according to the structural dimensions of the parts, thereby increasing the applicability of the entire device.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-3 As shown, the present invention provides a gripping mechanism for loading and unloading automotive parts, comprising a main frame 1, multiple support rods 2 fixedly installed on both sides of the main frame 1, and a side rod 3 fixedly connected between two support rods 2. Mounting seats 5 are fixedly installed on both sides of the main frame 1 and the side rods 3 between the two side rods 3. A transmission device 6 is fixedly installed on one side of the mounting seat 5. A transmission device 6 is movably installed at the bottom of the transmission device 6. A cylinder 7 is fixedly installed on the top of the transmission device 6, and the cylinder 7 is connected to an external air pump through an air pipe.

[0022] A robotic arm mounting flange 4 is fixedly installed at the top center of the main frame 1. The robotic arm mounting flange 4 is fixedly connected to the external robotic arm. The robotic arm mounting flange 4 is set on the main frame 1 to facilitate the use of the entire gripping mechanism with different models of robots. A hanging rod 9 is fixedly installed at the bottom of the side rod 3 near the mounting base 5. A proximity sensor 10 is fixedly installed at the bottom of the hanging rod 9. The proximity sensor 10 is electrically connected to the external main controller through a connecting wire. With the help of the proximity sensor 10, when the proximity sensor 10 approaches the part, the cylinder 7 is inflated and cooperates with the transmission device 6 and the gripper 8 to grip the workpiece.

[0023] The input end of the transmission device 6 is movably connected to the output end of the cylinder 7, and a rotating frame 11 is rotatably mounted on the output end of the transmission device 6. A gripper 8 is fixedly mounted on one side of the rotating frame 11, and the gripper 8 is also located below the transmission device 6. The rotating frame 11 is rotatably mounted on the outside of the transmission device 6, and the gripper 8 is fixedly mounted on one side of the rotating frame 11. This allows the gripper 8 to be flipped and opened in conjunction with the cylinder 7, thus facilitating the gripping of parts.

[0024] It should be noted that this utility model is a gripping mechanism for loading and unloading automotive parts. Before use, the robotic arm mounting flange 4 can be bolted to the end of the robotic arm. Then, multiple cylinders 7 are connected to an external air pump through air pipes. This allows the robotic arm to move the main frame 1 and side rods 3 to a designated position. Then, with the cooperation of the robotic arm, the main frame 1 and the two side rods 3 respectively drive multiple sets of transmissions 6, cylinders 7, and grippers 8 to move above the parts. Then, multiple proximity sensors 10 detect the position of the grippers 8 and the parts. When the grippers 8 move to the designated position, the external air pump supplies air to the multiple cylinders 7. Thus, the cylinders 7 drive the rotating frame 11 to rotate through the transmissions 6. This causes the rotating frame 11 to drive the grippers 8 to rotate. Thus, the rotation of the multiple grippers 8 can grip the parts and, with the cooperation of the robotic arm, transfer the parts to the designated position for unloading.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
