Description
Technical Field
[0001] A dynamic automatic loading system for automobile bumpers is disclosed, which enables a transport trolley to automatically load automobile bumpers during continuous movement, through the development of a dynamic automatic loading system and method for automobile bumpers. Background Technology
[0002] With the continuous development of the automotive industry, the demand for car bumpers has also increased significantly. Car bumper production mainly includes injection molding, painting, and assembly. First, the injection molding machine completes the injection molding of the car bumper. Then, the car bumper is mounted on a conveyor trolley on the painting line and transported to the spray painting line for painting and drying. Finally, the car bumper is assembled.
[0003] A utility model patent with patent number CN214454962U provides a flexible gripper and an automatic loading device. The flexible gripper includes a mounting base and a suction cup assembly, a first image sensor, a second image sensor, a distance sensor, a 3D camera, and a flip-up, position-avoiding light source assembly fixed to the mounting base. The suction cup assembly includes a suction cup and a first driving member, which is connected to the suction cup and drives the suction cup to rotate. The flip-up, position-avoiding light source assembly includes a position-avoiding light source and a second driving member, which is connected to the position-avoiding light source and drives the position-avoiding light source to flip. The suction cup, position-avoiding light source, first image sensor, second image sensor, distance sensor, and 3D camera are all located on the same side of the mounting base. This utility model's flexible gripper and automatic loading device can automatically adjust its relative position to the product and the posture of the suction cup based on its own sensors detecting the product's shape, thus adsorbing and fixing the product before transplanting it. This can meet the application needs of various bumper products. However, this patent actually uses its own sensors to adjust the loading mechanism and is unrelated to the automatic loading of car bumpers in this application.
[0004] A patent with patent number CN115532554A discloses a process for masking and painting textured bumper parts, including the following steps: raw material inspection, injection molding, appearance inspection, product surface wiping, applying mold pieces, applying masking tape, product loading, flame treatment, paint spraying, paint baking, product unloading, removing the masking film, appearance inspection, and packaging. The beneficial effects of this invention are: by integrating the part design, design costs are reduced; only one set of molds and injection molding equipment is needed, reducing equipment and tooling investment; and the part can achieve two different appearance effects, making the car exterior design more distinctive. However, this patent is actually unrelated to the automatic loading of car bumpers in this application, as it involves a process for masking and painting textured bumper parts.
[0005] Currently, there are two main ways to load car bumpers onto the painting line transport trolley: dynamic manual loading and fixed-point loading by robotic arms.
[0006] 1. Dynamic manual loading: The workpiece is manually taken from the car bumper preparation device and then placed on the moving transport trolley to complete the loading operation of the car bumper.
[0007] 2. Fixed-point loading of the robot arm: The loading robot arm automatically completes the loading operation of the car bumper. The loading robot arm grabs the car bumper from the car bumper preparation device and places it on the fixed-point transport trolley.
[0008] There are two existing loading methods, each with its own advantages and disadvantages:
[0009] The advantage of dynamic manual loading is that it eliminates the need for automated loading equipment for car bumpers. However, there are safety hazards for operators when working on a moving trolley.
[0010] The advantage of using robotic arms for fixed-point loading is that it saves labor and can automatically complete the loading of car bumpers. However, the fixed-point positioning of the transport trolley requires the addition of mechanical devices such as stoppers, front pushers, and rear pushers, resulting in a long car bumper loading station and high equipment investment. Summary of the Invention
[0011] The purpose of this invention is to enable a car bumper dynamic automatic loading system and method to automatically load car bumpers during continuous movement of a transport trolley, thereby reducing manual labor, eliminating safety hazards, and improving quality.
[0012] This invention comprises the following structure:
[0013] To achieve the above objectives, the present invention specifically adopts the following technical solution: The system includes: a conveying device, a control device, a loading device, and a switching device;
[0014] The control device includes a control panel, one end of which is connected to a switching device, and the other end of which is connected to a conveying device.
[0015] The conveying device includes conveying equipment and a conveying trolley located on the conveying equipment and moving together with the conveying equipment;
[0016] The conveying equipment is equipped with a first switch, a second switch, a third switch, a fourth switch, a fifth switch, a sixth switch, and a seventh switch in sequence along the direction of movement of the conveying equipment;
[0017] When the transport trolley moves to the first switch, the control panel controls the loading robot to obtain vehicle type information from the production instruction system; when the transport trolley moves to the second switch, the control panel controls the car bumper preparation device to provide the workpiece according to the vehicle type instruction; when the transport trolley moves to the third switch, the control panel controls the loading robot to precisely grab car bumper A workpiece at the car bumper preparation device; when the transport trolley moves to the fourth switch, the control panel controls the loading robot to place car bumper A workpiece onto the transport trolley; when the transport trolley moves to the fifth switch, the control panel controls the loading robot to precisely grab car bumper B workpiece at the car bumper preparation device; when the transport trolley moves to the sixth switch, the control panel controls the loading robot to place car bumper B workpiece onto the transport trolley; when the transport trolley moves to the seventh switch, the control panel controls the loading robot to complete the current work cycle and enter the next cycle.
[0018] Furthermore, the conveying equipment is a continuous production line, with the conveying trolley set on top of the conveying equipment for conveying the bumper. Since the production line is a continuously moving process, the conveying equipment is in a state of continuous movement.
[0019] Furthermore, the loading device includes a mechanical gripper that can rotate freely at the front end of the loading robot, and left and right cylinders and left and right wing walls are symmetrically arranged on the gripper frame of the mechanical gripper. At least two sets of large suction cup assemblies are respectively arranged on the left and right cylinders, and small suction cup assemblies are symmetrically arranged on the inner side of the left and right wing walls.
[0020] Furthermore, the left cylinder of the mechanical gripper of the upper part of the robot arm extends and retracts the left large suction cup device. When gripping is performed, the left cylinder extends and when not performing the gripping is performed, the left cylinder retracts. The right cylinder of the mechanical gripper of the upper part of the robot arm extends and retracts the right large suction cup device. When gripping is performed, the right cylinder extends and when not performing the gripping is performed, the right cylinder retracts.
[0021] Furthermore, the lower end of the transport trolley support column is fixedly connected to the traction chain in the pit. The I-beam structure is double-layered, and the double-layered I-beam structure is fixed to the top of the support column. The top of the support column is equipped with a double-layered I-beam structure transport trolley for placing the car bumper A workpiece and car bumper B workpiece, which are respectively grabbed by the upper part robot arm on the car bumper preparation device, and transferring the grabbed car bumper to the next process.
[0022] The beneficial effects of this invention are as follows:
[0023] (1) The present invention adopts a continuous production process of robotic arms. Therefore, the process of grabbing the bumper and sending it to the assembly line is completed automatically by the robotic arm. There is no need for manual loading, so there is no safety hazard to personnel.
[0024] (2) Since this device is fully automated, it operates in a flow according to a pre-set program during the production process. There is no need to set up stoppers, front and rear pushers or synchronization devices in the middle. Therefore, it has the advantages of high production efficiency and low equipment investment.
[0025] (3) Since this device adopts a continuous production process of robotic arms, it realizes fully automated loading. Therefore, there is no need for buffer stations before and after the loading station, which can save a lot of production line space. Attached Figure Description
