[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4This utility model provides a technical solution: an automatic stamping equipment with a loading and unloading robot, including a main body 1 and a motion mechanism 2. The motion mechanism 2 is fixedly installed inside the main body 1. The main body 1 includes a body 101, a shell 102, and a base 103. The shell 102 is fixedly installed on the surface of the body 101, and the base 103 is fixedly installed at the bottom of the body 101.

[0027] The motion mechanism 2 includes a loading robot 201, a unloading robot 202, and a gripper 203. The loading robot 201 is fixedly installed on the side of the machine body 101, and the unloading robot 202 is fixedly installed on the front end of the machine body 101. The gripper 203 is fixedly installed on the surface of the loading robot 201 and the unloading robot 202.

[0028] Furthermore, the main body 1 also includes a housing 104 and an electrical cabinet 105. The housing 104 is fixedly installed on the surface of the loading robot 201 and the unloading robot 202, and a plurality of electrical cabinets 105 are fixedly installed on the body 101.

[0029] Furthermore, the motion mechanism 2 also includes a slider 204 and a guide rail 205. The slider 204 is fixedly installed on the top of the front surface of the body 101, and the guide rail 205 is fixedly installed on the slider 204.

[0030] Furthermore, the main body mechanism 1 also includes an upper mold base 106 and a lower mold base 107. The upper mold base 106 is fixedly installed at the bottom end of the slider 204, and the lower mold base 107 is fixedly installed at the bottom end of the upper mold base 106.

[0031] Furthermore, the main body 1 also includes a worktable 108 and a workpiece 109. The worktable 108 is fixedly installed at the front end of the machine body 101, the lower mold base 107 is fixedly installed on the surface of the worktable 108, and the workpiece 109 is fixedly installed on the gripper 203.

[0032] Furthermore, the motion mechanism 2 also includes a motor 206, which is fixedly installed inside the body 101.

[0033] Furthermore, the motion mechanism 2 also includes a roller feeder 207, and the front end of the unloading robot 202 is fixedly mounted with the roller feeder 207.

[0034] Working Principle: The machine body 101 is a welded steel structure with high strength and rigidity, capable of withstanding the enormous pressure generated during stamping, ensuring equipment stability during operation and reducing vibration and deformation. Common forms include open and closed machine bodies 101. Open machine bodies 101 are open on three sides, facilitating operation and mold installation, but their rigidity is relatively weaker; closed machine bodies 101 have better rigidity and are suitable for high-tonnage stamping.

[0035] The slider 204, in conjunction with the guide rail 205 of the machine body 101, can perform reciprocating up and down motion. It is driven by a crank-connecting rod mechanism, toggle mechanism, or hydraulic system. An upper die is mounted on the lower part of the slider 204. During the stamping process, the slider 204 drives the upper die downwards to close with the lower die, thus achieving the stamping process of the sheet metal.

[0036] The mold mounting device includes an upper mold base 106 and a lower mold base 107, used to fix the stamping mold. The upper mold base 106 is mounted on the slide block 204, and the lower mold base 107 is mounted on the worktable 108. They are fastened and positioned using locating keys, bolts, etc., ensuring accurate and secure mold installation. The transmission system commonly includes mechanical and hydraulic transmissions. Mechanical transmission uses gears, crankshafts, connecting rods, and other components to convert the rotational motion of the motor 206 into the linear motion of the slide block 204; this method is often used in small high-speed stamping presses. Hydraulic transmission utilizes hydraulic pumps, hydraulic cylinders, etc., using hydraulic oil as the working medium to transmit power, providing greater stamping pressure, and is commonly used in large stamping equipment.

[0037] The housing 104 serves as the supporting frame for the robotic arm, protecting the internal mechanical components and electrical parts, while also providing a mounting base for other structures. The vertical motion mechanism 2 consists of a servo motor 206, a lead screw, and a guide rail 205. The servo motor 206 drives the lead screw to rotate, causing the robotic arm, connected to the lead screw nut, to move vertically up and down along the guide rail 205, enabling the robotic arm to pick up and unload materials vertically. The horizontal motion mechanism 2, also composed of a servo motor 206, a lead screw, and a guide rail 205, allows the robotic arm to move horizontally, used to transport the workpiece 109 from the loading / unloading position to the stamping die position, or to remove the stamped workpiece 109 from the die and place it in a designated position. The rotary motion mechanism 2, for example composed of a rotary cylinder or a servo motor 206 with a reducer, is used to rotate the gripper 203, facilitating adjustments to the posture and orientation of the workpiece 109 to meet different loading / unloading requirements.

[0038] The mechanical clamping device includes a pneumatic gripper 203 that can clamp and release via a cylinder, capable of gripping workpieces 109 of different shapes and sizes; and an electromagnetic chuck that uses electromagnetic force to attract metal workpieces 109.

[0039] The worktable 108 is used to install the lower die base 107 and place the workpiece 109 to be stamped. Its surface is flat and has a certain degree of hardness and wear resistance. Some worktables 108 are also equipped with positioning devices to ensure the accurate position of the workpiece 109 before stamping. The feeding device, a roller feeder, moves the sheet metal through the friction between the rollers and the sheet metal. These devices can accurately feed the sheet metal into the die for stamping at a set interval.

[0040] One robotic arm is located on the lower left side of the machine body 101, responsible for gripping the workpiece 109 to be processed from a specific position and placing it on the stamping die, completing the loading action; the other is located on the right side of the machine body 101, responsible for removing the stamped workpiece 109 from the die and placing it on the conveyor belt on the right side, realizing the unloading function. The robotic arm has multiple joints and a movable robotic arm, with gripping devices such as a gripper 203 at the end.

[0041] Power conversion: Motor 206 drives crank to rotate via belts, gears, and other transmission components. Under the action of crank-connecting rod mechanism or crank-toggle mechanism, the circular motion of motor 206 is converted into the reciprocating linear motion of slider 204. For example, in a mechanical punch press, the rotation of motor 206 drives flywheel to rotate, which, through the clutch, causes gears, crankshaft, connecting rod, etc., to rotate, achieving the linear motion of slider 204.

[0042] In the stamping process, the slide block 204 drives the upper die mounted on it to move up and down. When the slide block 204 moves downward, the upper die closes with the lower die mounted on the worktable 108, applying pressure to the sheet metal placed between them. Under the action of pressure, the sheet metal undergoes plastic deformation to obtain the required shape and precision. The reaction force generated by the stamping force is borne by the press body 101.

[0043] The loading process begins with the sheet metal to be processed being placed at a designated loading position, such as a rack. Sensors on the robotic arm detect the position and orientation of the sheet metal. Then, driven by vertical, horizontal, and rotary motion mechanisms 2, the pneumatic gripper 203 moves above the sheet metal. The actuator grasps the sheet metal and moves it along a planned path, accurately placing it onto the stamping die, thus completing the loading process.

[0044] In the unloading process, after stamping, the slider 204 moves upward back to the top dead center. The unloading robot arm 202 moves, and the gripper 203 moves into the mold to grab the stamped workpiece 109. Then, the robot arm moves along a predetermined trajectory to transport the workpiece 109 to the roller feeder 207, and the gripper 203 releases, completing the unloading process.

[0045] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
