[0049] like Figures 1 to 4 As shown, an automatic loading and unloading system suitable for the punching production of thin-plate metal parts is provided on the working surface of the punching machine 12. The working surface of the punching machine 12 is provided with a punching seat 20 and a die pad 9. The die pad 9 is provided on the punching seat 20. The automatic loading and unloading system includes a loading device, an unloading device and a horizontal moving device.

[0050] The loading device is provided on one side of the punching seat 20 for placing the punching gasket to be processed and for loading the punching press 12;

[0051] The unloading device is provided on the other side of the stamping seat 20 and is arranged opposite to the loading device, and is used to place the stamped gasket after processing;

[0052] The horizontal moving device is arranged above the stamping seat 20, and a clamping component is provided on the horizontal moving device. The horizontal moving device can move the stamped gasket to be processed from the loading device to the mold pad 9, and the horizontal moving device can move the stamped gasket after processing from the mold pad 9 to the unloading device.

[0053] The purpose of this design is to provide an automatic loading and unloading system that includes a loading device, an unloading device, and a horizontal moving device. This loading and unloading system is built based on the characteristics of thin-plate metal parts and is equipped with high-precision motion control characteristics. Through the collaborative operation of the clamping components, it can achieve precise gripping of the plates, rapid mold change, and safe transportation, and synchronize with the beat of the stamping equipment to complete the full process automation closed loop. This integrated solution can not only break through the production bottleneck of the traditional operation mode, but also fundamentally reconstruct the safety boundaries of high-risk processes by eliminating the human-computer interaction link. It solves the problem that existing technical solutions often find it difficult to take into account the diversity of plate shapes, the complexity of processing paths, and the need for dynamic adjustment.

[0054] At the same time, in this embodiment, a specific composition of a loading device is provided, wherein the loading device includes a loading base 1, a first column 21 and a second column 22;

[0055] The loading base 1 is fixed on the ground;

[0056] The first column 21 and the second column 22 are both arranged on the loading base 1, and the first column 21 is provided with a vertical module 2;

[0057] The vertical module 2 is provided with a vertically movable pallet manipulator 4;

[0058] An adjusting nut 3 is provided on the top of the second column 22;

[0059] A feeding guide rod 5 passes through the adjusting nut 3 , and a stamping gasket to be processed passes through the feeding guide rod 5 , and the stamping gasket to be processed can move upward under the action of the pallet manipulator 4 .

[0060] 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 loading guide rod. The two are set relative to each other. During use, the vertical module drives the pallet manipulator to move in the vertical direction by the lifting motor after receiving the external control signal. At the same time, according to the actual needs of processing the size of the gasket, the on-site staff can manually turn the adjusting nut to adjust the height of the loading guide rod.

[0061] Furthermore, in a specific processing scenario, on-site staff now put the gasket to be processed on the loading guide rod and press the pallet robot underneath.

[0062] At the same time, in this embodiment, a support cross bar 23 is provided between the first column 21 and the second column 22 , and one end of the support cross bar 23 is connected to the bottom of the first column 21 , and the other end of the support cross bar 23 is connected to the bottom of the second column 22 .

[0063] The purpose of this design is that in the previous structure, the two columns were set in isolation on the loading base. During the long-term use of the vertical module, shaking or instability will inevitably occur. Therefore, by setting a supporting cross bar to connect the first column and the second column, the two can share the shaking and improve the overall stability.

[0064] Furthermore, this embodiment provides an automatic control method, and a positioning groove 24 is provided on the top of the feeding guide rod 5;

[0065] A sensor support frame 7 is provided on the upper portion of the first column 21, and a feeding sensor 6 is installed at the end of the sensor support frame 7;

[0066] 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.

[0067] The purpose of this design is that, through the coordination of the positioning groove and the loading sensor, the loading sensor can sense whether the gasket 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 loading guide rod. The positioning groove here, its groove shape and size are usually adapted to the shape and size of the vacuum manipulator behind it, so that it can grab the gasket to be processed from the inside.

[0068] In this embodiment, a specific composition of a material unloading device is also provided, wherein the material unloading device includes a material unloading guide rod 17 and a material unloading platform 18;

[0069] The blanking guide rod 17 is provided on the blanking platform 18;

[0070] The blanking platform 18 is detachably connected to the punching seat 20 .

[0071] At the same time, a connecting rod 25 is provided on one side of the unloading platform 18 , and one end of the connecting rod 25 can be hung on the side wall of the punching seat 20 .

[0072] The purpose of this design is that after the punching is completed, the processed gasket will be transferred to the blanking guide rod via the horizontal moving device for use in subsequent processes. The blanking platform is used to support the blanking guide rod, and at the same time, it is fixed to the side wall of the stamping seat with detachable structures such as connecting rods and screws, which is convenient for disassembly and movement.

[0073] In this embodiment, a specific structure of a punching seat is also provided, wherein a first slide groove 26 and a second slide groove 27 are provided on the upper surface of the punching seat 20;

[0074] The first slide groove 26 is located in the middle of the upper surface of the punching seat 20 and is parallel to the long side of the punching seat 20;

[0075] The second sliding groove 27 is close to the edge of the punching seat 20 and is parallel to the first sliding groove 26 .

[0076] At the same time, 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 a connecting piece. 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 straight line where the vertical projection of the loading guide rod 5 and the vertical projection of the unloading guide rod 17 are located.

[0077] The purpose of this design is to set up the first slide and the second slide, where the first slide can be used to adjust the position of the mold pad. In this way, when the equipment is debugged, the on-site staff can adjust the relative positions of the mold, loading guide rod and unloading guide rod according to actual conditions, so that the three are located on the same straight line, and the mold is located at the midpoint of the line connecting the loading guide rod and the unloading guide rod. This can greatly reduce the time for adjusting the vacuum manipulator.

[0078] 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, and then fixed and limited by existing structures such as fixing bolts.

[0079] At the same time, it should be pointed out that in order to make the installation of the punching seat more stable, a punching base is also provided on the working surface of the punching machine to support and fix the punching seat.

[0080] 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 manipulator support 16. The bottom of the horizontal module 8 is mounted in the second slide groove 27 through a first mounting seat 28. The power output end of the horizontal module 8 is detachably connected to the manipulator support 16.

[0081] The bottom of the manipulator bracket 16 is installed in the second slide groove 27 through the second mounting seat 29;

[0082] The first mounting seat 28 and the second mounting seat 29 are respectively disposed at two ends of the second sliding groove 27 .

[0083] At the same time, the manipulator bracket 16 is provided with a clamping component, and the clamping component includes a first vacuum manipulator 11, a second vacuum manipulator 14, a first cylinder 13 and a second cylinder 15;

[0084] The first vacuum manipulator 11 and the second vacuum manipulator 14 are arranged alternately, and the distance between the first vacuum manipulator 11 and the second vacuum manipulator 14 is equal to the distance between the mold 10 and the blanking guide rod 17;

[0085] The first cylinder 13 and the second cylinder 15 are arranged on the side of the manipulator bracket 16 facing away from the mold 10, and the power output end of the first cylinder 13 is connected to the first vacuum manipulator 11, which can drive the first vacuum manipulator 11 to rise and fall. The power output end of the second cylinder 15 is connected to the second vacuum manipulator 14, which can drive the second vacuum manipulator 14 to rise and fall.

[0086] 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. Usually, they include structures such as stepper motors and slide rails. After receiving instructions from the controller, the stepper motor enables the controlled component to move vertically or horizontally on the slide rails. Of course, as far as the horizontal module and the vertical module themselves are concerned, they are a kind of existing technology and are only described here as functions.

[0087] In a specific usage scenario, the on-site staff presses the loading button, and the vertical module 2 drives the tray robot 4 to move downward to the limit position. The on-site staff places the gasket to be processed through the loading guide rod 5 on the supporting robot 4. The gasket to be processed is driven to rise by the vertical module 2 until the loading sensor 6 senses the gasket and stops rising. At this time, the gasket to be processed moves to the end of the loading guide rod 5, and the loading is completed.

[0088] Then press the automatic operation button to enter the automatic loading and unloading cycle step: the power output end of the horizontal module 8 drives the manipulator bracket 16 to move, and the first vacuum manipulator 11 and the first vacuum manipulator 12 move left to the left station. The first vacuum manipulator 11 is concentric with the loading guide rod 5, and the first vacuum manipulator 12 is concentric with the mold 10. Then the first cylinder 13 and the second cylinder 15 move downward at the same time. The first vacuum manipulator 11 grabs the gasket and the first vacuum manipulator 12 grabs the punched product in the mold 10. Then the first cylinder 13 and the second cylinder 15 move upward to complete the material removal.

[0089] The power output end of the horizontal module 8 drives the manipulator bracket 16 to move right to the right workstation, the first cylinder 13 and the second cylinder 15 move downward together, the first vacuum manipulator 11 places the gasket in the mold 10, and the first vacuum manipulator 12 places the punched sheet on the unloading guide rod. The first cylinder 13 and the second cylinder 15 move upward to complete the unloading; the horizontal module 8 moves to the left to a safe distance, and the punching machine 12 performs a punching. The above steps are completed in sequence as an automatic cycle.

[0090] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
