[0026] like Figures 1 to 4As shown, an automatic loading and unloading system suitable for the stamping production of thin sheet metal parts is provided. The automatic loading and unloading system is located at the working surface of the stamping machine 12. The working surface of the stamping machine 12 is provided with a stamping seat 20 and a mold pad 9. The mold pad 9 is located on the stamping seat 20. The automatic loading and unloading system includes a loading device, an unloading device and a horizontal moving device. The feeding device is located on one side of the stamping base 20 and is used to place the stamping pads to be processed and to feed the stamping machine 12. The unloading device is located on the other side of the stamping base 20 and is opposite to the loading device, and is used to place the processed stamping pad; The horizontal moving device is located above the stamping base 20. The horizontal moving device is equipped with a clamping component. The horizontal moving device can move the stamping pad to be processed from the feeding device to the mold pad 9. The horizontal moving device can also move the processed stamping pad from the mold pad 9 to the unloading device.

[0027] The purpose of this design is to provide an automated loading and unloading system that includes a feeding device, an unloading device, and a horizontal moving device. Based on the characteristics of thin sheet metal parts, and combined with high-precision motion control, this system enables precise sheet metal gripping, rapid shape change, and safe transfer through the coordinated operation of clamping components. It synchronously matches the cycle time of the stamping equipment to complete a fully automated closed loop. This integrated solution not only breaks through the production bottlenecks of traditional operating modes but also fundamentally reconstructs the safety boundaries of high-risk processes by eliminating human-machine interaction. It solves the problem that existing technologies often struggle to accommodate the diversity of sheet metal shapes, the complexity of processing paths, and the need for dynamic adjustments.

[0028] Meanwhile, this embodiment provides a specific composition of a feeding device, wherein the feeding device includes a feeding base 1, a first column 21 and a second column 22; The feeding base 1 is fixed to the ground; The first column 21 and the second column 22 are both mounted on the loading base 1, and the first column 21 is provided with a vertical module 2; The vertical module 2 is equipped with a vertically movable pallet robot 4. The second column 22 is equipped with an adjusting nut 3 at its top; The adjusting nut 3 has a feeding guide rod 5 passing through it, and the feeding guide rod 5 has a stamping pad to be processed passing through it. Under the action of the pallet robot 4, the stamping pad can move upward.

[0029] The purpose of this design is that the first column is used to support the vertical module, and the second column is used to support the feeding guide rod. The two are set up opposite each other. In use, after receiving an external control signal, the vertical module is driven by the lifting motor to move the pallet robot vertically. At the same time, according to the actual needs of processing the size of the shims, the on-site staff can manually turn the adjusting nut to adjust the height of the feeding guide rod.

[0030] Furthermore, in a specific processing scenario, the on-site staff first place the pad to be processed onto the feeding guide rod and then press the pallet robot arm down below.

[0031] Meanwhile, in this embodiment, a support crossbar 23 is provided between the first column 21 and the second column 22, and one end of the support crossbar 23 is connected to the bottom of the first column 21, and the other end of the support crossbar 23 is connected to the bottom of the second column 22.

[0032] The purpose of this design is that, in the previous structure, the two columns were set up in isolation on the loading base. During long-term use of the vertical module, swaying or instability would inevitably occur. Therefore, by setting up a support crossbar to connect the first and second columns, the two columns can share the swaying and improve the overall stability.

[0033] Furthermore, this embodiment provides an automatic control method, wherein a positioning groove 24 is provided on the top of the feeding guide rod 5; A sensor support frame 7 is provided on the upper part of the first column 21, and a feeding sensor 6 is installed at the end of the sensor support frame 7; The image acquisition end of the feeding sensor 6 faces the positioning groove 24, and the feeding sensor 6 can transmit the acquired image information to the controller.

[0034] The purpose of this design is to use the positioning groove and the feeding sensor to detect whether the pad to be processed has moved to the appropriate position under the drive of the vertical module. After it moves to the appropriate position, the controller will control the horizontal moving device to grab it, thereby separating it from the feeding guide rod. The shape and size of the positioning groove are usually adapted to the shape and size of the vacuum robot behind it, so that it can grab the pad to be processed from the inside.

[0035] In this embodiment, a specific composition of a feeding device is also provided, wherein the feeding device includes a feeding guide rod 17 and a feeding platform 18; The unloading guide rod 17 is mounted on the unloading platform 18; The unloading platform 18 is detachably connected to the stamping base 20.

[0036] Meanwhile, a connecting rod 25 is provided on one side of the unloading platform 18, and one end of the connecting rod 25 can be attached to the side wall of the stamping seat 20.

[0037] The purpose of this design is that after the stamping is completed, the finished gasket will be transferred to the unloading guide rod via a horizontal moving device for use in subsequent processes. The unloading platform is set up to support the unloading guide rod, and at the same time, it is fixed to the side wall of the stamping seat by a detachable structure such as connecting rods and screws, which facilitates disassembly and movement.

[0038] In this embodiment, a specific structure of a stamping seat is also provided, wherein the upper surface of the stamping seat 20 is provided with a first sliding groove 26 and a second sliding groove 27; The first groove 26 is located in the middle of the upper surface of the stamping base 20 and is parallel to the long side of the stamping base 20; The second slide groove 27 is close to the edge of the stamping seat 20 and is parallel to the first slide groove 26.

[0039] Meanwhile, the bottom of the mold pad 9 can be inserted into the first slide groove 26 and is detachably connected to the stamping seat 20 through the connector. The mold 10 is installed on the top of the mold pad 9, and the vertical projection of the mold 10 is located at the center of the line where the vertical projection of the feeding guide rod 5 and the vertical projection of the unloading guide rod 17 are located.

[0040] The purpose of this design is to allow on-site personnel to adjust the relative positions of the mold, feeding guide rod, and unloading guide rod during equipment debugging by setting up a first and a second sliding groove. The first sliding groove can be used to adjust the position of the mold pad block. This ensures that the three are aligned on a straight line, with the mold located at the midpoint of the line connecting the feeding guide rod and the unloading guide rod. This significantly reduces the time required to adjust the vacuum manipulator.

[0041] When making adjustments, the mold to be processed can be placed on the mold pad first, then the mold pad can be inserted into the first slide groove, and then pushed to move on the first slide groove to move it to the appropriate position. Then, it can be fixed and limited by existing structures such as fixing bolts.

[0042] It should also be noted that, in order to make the stamping base more stable, a stamping base is also provided on the working surface of the stamping machine for supporting and fixing the stamping base.

[0043] In this embodiment, a specific structure of a horizontal moving device is also provided, wherein the horizontal moving device includes a horizontal module 8 and a robotic arm support 16. The bottom of the horizontal module 8 is mounted in the second slide groove 27 through a first mounting base 28, and the power output end of the horizontal module 8 is detachably connected to the robotic arm support 16. The bottom of the robotic arm support 16 is mounted in the second slide groove 27 via the second mounting base 29; The first mounting base 28 and the second mounting base 29 are respectively located at both ends of the second slide groove 27.

[0044] Meanwhile, the robotic arm support 16 is provided with a clamping component, which includes a first vacuum robotic arm 11, a second vacuum robotic arm 14, a first cylinder 13 and a second cylinder 15; The first vacuum robot 11 and the second vacuum robot 14 are arranged alternately, and the distance between the first vacuum robot 11 and the second vacuum robot 14 is equal to the distance between the mold 10 and the unloading guide rod 17. The first cylinder 13 and the second cylinder 15 are located on the side of the robot arm bracket 16 facing away from the mold 10. The power output end of the first cylinder 13 is connected to the first vacuum robot arm 11, which can drive the first vacuum robot arm 11 to rise and fall. The power output end of the second cylinder 15 is connected to the second vacuum robot arm 14, which can drive the second vacuum robot arm 14 to rise and fall.

[0045] The purpose of this design is that the horizontal module and the previously mentioned vertical module are similar in function, both providing movement in one direction. They typically include a stepper motor, a slide rail, and other structures. After receiving instructions from the controller, the stepper motor enables the controllable device to make vertical or horizontal displacements on the slide rail. Of course, the horizontal and vertical modules themselves are existing technologies, and are only used here for functional description.

[0046] In a specific application scenario, the on-site staff presses the loading button, and the vertical module 2 drives the pallet robot 4 to move downward to its limit position. The on-site staff places the pad to be processed through the loading guide rod 5 onto the pallet robot 4. The pad to be processed is driven upward by the vertical module 2 until the loading sensor 6 senses the pad and stops rising. At this time, the pad to be processed moves to the end of the loading guide rod 5, and the loading is completed.

[0047] Next, press the automatic operation button to engage the automatic loading and unloading cycle: the power output end of the horizontal module 8 drives the robot arm bracket 16 to move, and the first vacuum robot arm 11 and the second vacuum robot arm 14 move to the left to the left work position. The first vacuum robot arm 11 is concentric with the loading guide rod 5, and the second vacuum robot arm 14 is concentric with the mold 10. Then the first cylinder 13 and the second cylinder 15 move downwards at the same time. The first vacuum robot arm 11 grabs the pad, and the second vacuum robot arm 14 grabs the punched product in the mold 10. Then the first cylinder 13 and the second cylinder 15 move upwards to complete the material handling. The power output end of the horizontal module 8 drives the robot arm bracket 16 to move to the right to the right work position. The first cylinder 13 and the second cylinder 15 move downwards together. The first vacuum robot arm 11 places the pad into the mold 10. The second vacuum robot arm 14 places the stamped sheet onto the unloading guide rod. The first cylinder 13 and the second cylinder 15 move upwards to complete the unloading. The horizontal module 8 moves to the left at a safe distance, and the stamping machine 12 performs one stamping. The above steps are completed in sequence to form an automatic cycle.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
