[0002] Automation of stamping equipment is an inevitable choice for the development of the machinery manufacturing industry, especially the stamping industry. Currently, stamping automation generally adopts the method of using robot-specific grippers and a material table. However, the current stamping automation method has the following problems:

[0003] 1. Limited product applicability; 2. Changing the product within the applicability range requires changing the feeding tooling and robot grippers; 3. Lack of detection for stacked products, causing mold damage. Utility Model Content

[0004] This invention provides an automated feeding system for stamping, which aims to solve the problems in the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] An automated stamping feeding system includes a worktable, a feeding robot, a turntable, and a stacking detection mechanism. The turntable is horizontally rotatable and mounted on the worktable. Multiple feeding racks for placing parts to be processed are evenly spaced around the turntable. The feeding robot is fixedly mounted on the worktable, located beside the turntable, and is used to deliver the parts to be processed from the feeding racks to the processing position. The stacking detection mechanism is fixedly mounted on the worktable and is used to detect whether the feeding robot has picked up a single part to be processed.

[0007] The beneficial effects of this utility model are: during the feeding process, a batch of parts to be processed are placed on multiple feeding racks. When the turntable rotates to the feeding position of one of the feeding racks, the feeding robot grabs the parts to be processed on the feeding rack and sends them to the stamping machine for stamping operation.

[0008] During this process, the stacking detection mechanism is used to detect whether the loading robot is grabbing a single part to be processed. If it is detected that the loading robot is grabbing multiple parts to be processed, manual processing is required in a timely manner.

[0009] This utility model has a simple structure and reasonable design, and can be used for feeding risers of different specifications without changing the chucks, making it widely applicable. In addition, production can be started after feeding once, and feeding can be continuous without interruption during the production process, which is highly efficient. At the same time, it also has a stacking detection function, and the gripping and releasing detection is stable and reliable, effectively preventing mold damage caused by stacking.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0080] Furthermore, the aforementioned workbench 1 is equipped with a master start button, which is communicatively connected to the controller.

[0081] The working principle of this utility model is as follows:

[0082] 1. Place the part in the universal rotary table fixture, press the start button, and the robot will start working. After grabbing the part, it will move to the stacking detection point (a high-precision inductive switch is used to detect changes in the height of the part. If the part is stacked, the robot will issue an alarm and the machine will stop running). After confirming that the grabbing is correct, it will move to the equipment mold. The multi-functional suction cup will grab the processed part. Rotate the part grabbing mechanism, and the other end of the multi-functional suction cup will release and place the part to be processed (if the part grabbing fails, the equipment will issue an alarm and the machine will stop running). The robot will exit, place the processed part in the part box, and repeat the grabbing of the next part.

[0083] 2. After the part is placed on the general-purpose turntable fixture, the ejection mechanism will eject the part to the designated position for the robot to grasp. After the robot grasps one part and moves away from the designated height, the ejection mechanism will continue to eject the part to the designated position.

[0084] 3. After all the parts of a tooling are processed, the turntable will automatically rotate to rotate the next station to the designated position and continue to lift the parts to the designated position.

[0085] 4. The robot repeatedly performs the parts gripping and placing process.

[0089] 3. The feeding fixture adopts a universal structure, and the parts are widely applicable;

[0090] 4. Stacking detection and gripping detection are stable and reliable, effectively preventing mold damage caused by stacking.

[0091] It should be noted that all electronic components involved in this utility model adopt existing technology, and all the above-mentioned components are electrically connected to the controller, and the control circuit between the controller and each component is existing technology.
