Description

Technical Field

[0001] The present invention relates to the technical field of stamping production lines, and in particular to an intelligent automatic stamping production line and an operating method thereof. Background Art

[0002] Press is a general term for mechanical press, hydraulic press and pneumatic press. Among them, mechanical press is a general press with exquisite structure. It has the characteristics of wide application and high production efficiency. Press can be widely used in cutting, punching, blanking, bending, riveting and forming. The metal is processed into parts by applying strong pressure to the metal blank to cause plastic deformation and fracture. When the mechanical press is working, the motor drives the large pulley (usually also serves as a flywheel) through the belt, and drives the crank slider mechanism or multi-link mechanism through the gear pair and clutch, so that the slider and the punch go down in a straight line. After the forging work of the mechanical press is completed, the slider moves upward, the clutch is automatically disengaged, and the brake on the crank shaft is turned on, so that the slider stops near the top dead center.

[0059] in:

[0060] Destacking trolley: The destacking trolley is mainly composed of a body, a lifting mechanism, an auxiliary scissor support and a moving guide rail. The rails of the two trolleys are arranged perpendicular to the logistics direction of the stamping line, and the two trolleys are used alternately to ensure continuous production. The main body of the destacking trolley is a welded structure of steel plates and profiles, and a drive motor and a lifting device are installed on the main body. The four driving wheels are used to drag the trolley in and out of the production line. The positioning of the trolley's travel limit position is controlled by a travel switch installed on the body. Its table is used to carry material stacks and pallets. The destacking trolley is equipped with two last sheet detection switches. When the last sheet switch sends a signal, the manipulator automatically turns to the other one. When the destacking trolley is empty, it will automatically drive out and stop, and sound and light alarm personnel to avoid, reminding the operator to load the trolley. The entry and exit of the trolley are automatically controlled. As long as the operator presses the start button, all actions are automatically completed (including automatic opening and closing of the door). The destacking trolley drive is powered by batteries. After the destacking trolley enters the destacking station, it automatically rises until the top sheet triggers the sensor, so that the top sheet is within the working range of the magnetic separation. As the height of the stack decreases, the trolley automatically rises to ensure that the destacking height is basically constant. The destacking trolley is equipped with a set of side stop devices on each side, and the position is manually adjusted to prevent the sheet from deviating to the left or right due to separation.

[0061] Splitter: The splitter is used to separate the stack of materials into layers. The splitter can automatically extend and retract, and the spacing can be automatically adjusted. The splitter includes a transverse movement, a cylinder-driven telescopic system, and a splitting structure. The splitter consists of a magnetic splitting mechanism and an air-blowing splitting mechanism. Magnetic splitting is used when producing steel plates, and air-blowing splitting is used when producing aluminum plates. The splitting structure is installed at the end of the moving mechanism, and its main function is to contact or act on the side of the stack to split the sheet material.

[0062] Visual alignment system: The alignment system uses the visual alignment system of Cognex Corporation of the United States, which can accurately identify the position and angle of at least 100 different types of sheet materials. All software is Cognex standard configuration integrated software. The visual optical alignment system can measure the position of the sheet material and confirm the position of the sheet material. The manipulator adjusts the gripping posture of the manipulator according to the detection results to accurately grip the sheet material.

[0063] Discharging belt conveyor: The discharging belt conveyor is a wide conveyor belt, and its main function is to transport the finished workpieces outside the stamping line so that workers can check and pack them outside the line. The discharging belt conveyor is mainly composed of a support bracket, a belt conveyor body, a belt, a roller and a drive system. The support bracket is a profile welded frame structure, which mainly serves as the installation basis for other parts. The belt conveyor is driven by a variable frequency reduction motor and a flat belt, and the speed can be adjusted by variable frequency. The belt conveyor has a tensioning belt mechanism and a safety lifting device; the belt of the belt conveyor uses high-quality products, and the surface of the belt is covered with a cutting-resistant layer, which is resistant to cutting by stamping parts and not easy to age. There should be no peeling or slag during use; the belt has a deviation adjustment device.

[0064] First double material detection: The first double material detection can also be installed on the depalletizing end picker according to the needs. It is a contact detection. It mainly consists of a controller, two probes and a probe fixed buffer structure.

[0065] Second double material detection: The second double material detection is mainly composed of a controller and two sets of necessary probe structures.

[0067] Step 1: The sheets are stored and transported by the destacking trolley. After the destacking trolley is located on one side of the destacking robot, the sheets on the destacking trolley are separated by a separator to avoid the phenomenon that multiple groups of sheets are attached together;

[0068] Step 2: Pick up the sheet material by the destacking end picker, and then adjust the position of the destacking end picker by the destacking robot to place the sheet material on the feeding belt conveyor. In this process, the first double material detection is used to determine whether the sheet material picked up by the destacking end picker is a double material, and the second double material detection is used to determine whether the sheet material on the transition belt conveyor is a double material;

[0069] Step 3: When the sheet material picked up by the depalletizing end picker and the sheet material on the transition belt conveyor are double materials, the personnel will be reminded through the reminder module;

[0070] Step 4: When the sheet material moves on the feeding belt conveyor, the drawing oil will be applied to the surface of the sheet material on the feeding belt conveyor through the oiler;

[0071] Step 5: After the coating is completed, the sheet will be moved to the transition belt conveyor for movement, and finally to the centering belt conveyor for movement;

[0072] Step 6: When the sheet is moved to the centering belt conveyor, the sheet will be picked up by the loading end picker, and then the loading robot drives the loading end picker to pick up the sheet and send it to the first press cavity to place the sheet on the first press in the press series line.
