[0030] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0031] like Figure 1-Figure 8A C-type structure four-column servo punch shown includes a punch body 1, which is a C-type structure servo punch. The C-type structure servo punch is significantly more energy-efficient than a traditional punch, usually 40% more energy-efficient than an ordinary hydraulic punch, and 50% more energy-efficient than a pneumatic and mechanical punch. This is due to its advanced servo motor and hydraulic system, which can achieve efficient energy conversion and utilization. Compared with traditional punches, the C-type structure servo punch has lower noise. This is due to its advanced hydraulic system and servo motor, which reduces mechanical friction and vibration, thereby reducing noise pollution. Its workbench and columns are C-shaped structures. In short, it has the advantages of light body, upstairs access, and quietness; the main body is a C-shaped mouth, the four columns are moving guide columns, and the middle is the punching part.

[0032] A suspension arm limit seat 2 is fixedly connected to the punch body 1, a suspension arm 3 is installed on the suspension arm limit seat 2, suction cup grippers 4 are installed on both sides of the suspension arm 3, a protective cover 5 is slidingly provided on the inner wall of the bottom end of the punch body 1, a connecting rod group 6 is rotatably connected in the protective cover 5, an adjustment seat 7 is rotatably connected between the two connecting rod groups 6, a punch maintenance mechanism 8 is rotatably connected in the adjustment seat 7, and a filter seat 9 is fixedly connected to the inner wall of the bottom end of the punch body 1. The four-guide column servo mechanism is used to replace the traditional punch slider structure, and the suspension arm 3 is added.

[0033] A series of mechanisms such as the front suction cup gripper 4, auxiliary tooling, and auxiliary processing mechanisms can be suspended to make the punching machine more comprehensive, with better equipment utilization and higher space utilization. The length, width, and height of the punching machine body 1 are 1052MM, 660MM, and 1810MM respectively, the die height is 170-210MM, the crankshaft diameter is 40MM, and the table size is 600×540MM. In this part of the design, a front suspension arm is used, which is mainly used in the FPC and FPCA fields. The front placement of the manipulator can facilitate the reservation of installation positions for other manipulators.

[0034] The punch body 1 is designed as a C-type punch, so that the suction cup gripper 4 can reach the punching position inside the punch body 1 during the lateral movement, effectively optimizing the stroke. Therefore, the structure of the suspension arm 3 and the suction cup gripper 4 can be made very short, and the overall volume can be made very small to reduce the floor space and weight, making it easier to move and place, and lighter in weight, so that it is convenient for one or more people to carry it to the desired location.

[0035] The main motor output of the punching machine body 1 drives the flywheel to rotate. The flywheel drives the large gear through the shaft and the small gear. The large gear is then connected to the crankshaft through the clutch. When the clutch is engaged, the power of the flywheel is transmitted to the crankshaft, causing it to start rotating. There is an eccentricity between the crankshaft and the connecting rod, which enables the connecting rod to produce reciprocating linear motion when the crankshaft rotates. One end of the connecting rod is connected to the crankshaft, and the other end is connected to the slider, thereby converting the rotational motion of the crankshaft into the linear motion of the slider. Driven by the crankshaft mechanism, the slider performs reciprocating linear motion along the bed rail. When the slider moves downward, it applies pressure to the material placed in the mold, causing it to undergo plastic deformation; when the slider moves upward, a stamping cycle is completed and ready for the next stamping action. This part is prior art and will not be described in detail. In this solution, the punch force can be adjusted to 25 tons to 45 tons.

[0036] It should be added that: the front placement of the suspension arm 3 leaves space for installing other robotic arms in the front, so that several robotic arms can be installed in a stacked manner.

An air pump 503 is fixedly installed on the protective cover 5, and the output end of the air pump 503 extends to the inside through the outer wall of the protective cover 5. The electric push rod 501 is used to drive the protective cover 5 to move upward for punching protection.

[0038] like Figure 6 As shown, a motor 601 is fixedly connected to the bottom end of one of the connecting rod groups 6, and the motor 601 is fixedly connected to the inner wall of the protective cover 5. The motor 601 drives the connecting rod group 6, so that the connecting rod group 6 drives the adjustment seat 7 to move between the stamping seat and the base.

[0039] like Figure 6 As shown, an air guide groove 701 is provided on the inner wall of the adjustment seat 7, a hose 702 is connected and fixedly provided on one side of the adjustment seat 7, the other end of the hose 702 is connected and fixedly provided with the output end of the air pump 503, a conduit ring 703 is slidably provided on the hose 702, a slider 704 is connected and fixedly provided on the lower side of the conduit ring 703, the slider 704 is slidably provided with the inner wall of the protective cover 5, a tension spring 705 is connected and fixedly provided on one end of the slider 704, and the other end of the tension spring 705 is connected and fixedly provided with the inner wall of the protective cover 5. The air pump 503 is used to inject high-pressure air into the hose 702, and then it is injected into the air guide groove 701 through the hose 702. Under the action of the tension spring 705, the conduit ring 703 connected to the slider 704 is moved, and the hose 702 is bent and stored.

[0040] like Figure 7As shown, the punch maintenance mechanism 8 includes an impeller 801, which is rotatably connected to the inner wall of the air guide groove 701, and a driving wheel 802 is fixedly connected to the outer end of the impeller 801. A transmission wheel 803 is meshed and driven on one side of the driving wheel 802, and the transmission wheel 803 is rotatably connected to the lower surface of the adjustment seat 7. The high-pressure air will drive the impeller 801 to rotate, so that the impeller 801 can drive the connected driving wheel 802 to rotate, so that the driving wheel 802 drives the transmission wheel 803 to rotate, and then the transmission wheel 803 drives the rotating tube 805 connected to the driven wheel 804 to rotate.

[0041] A driven wheel 804 is meshingly provided on one side of the transmission wheel 803 for transmission, a rotating tube 805 is fixedly connected to the driven wheel 804, the rotating tube 805 is rotatably connected to the adjustment seat 7, an air guide port 806 is opened in the middle of the rotating tube 805, and nozzles 807 are fixedly connected to both ends of the rotating tube 805 in a fan-shaped structure.

[0043] An air inlet pipe 903 is fixedly connected to one side of the filter seat 9, and the other end of the air inlet pipe 903 is fixedly connected to the inner wall of the punch body 1. A rotating shaft 904 is rotatably connected in the filter seat 9, and a cover plate 905 is fixedly connected to the bottom end of the rotating shaft 904. Two filter screens 906 are fixedly connected to the cover plate 905. The top end of the rotating shaft 904 passes through the inner wall of the filter seat 9 and extends to the outside and is fixedly connected to a worm gear 907.

[0044] A rotating rod 908 is rotatably connected to the upper surface of the filter seat 9, one end of the rotating rod 908 is connected and fixedly provided with a worm 909, and the other end of the rotating rod 908 extends to the inner wall of the punch body 1 and is connected and fixedly provided with an adjusting wheel 910, and the adjusting wheel 910 is meshed and driven with the adjusting rack 502. The adjusting rack 502 drives the adjusting wheel 910 to rotate, so that the adjusting wheel 910 drives the connected rotating rod 908 to rotate, and then the rotating rod 908 can drive the worm 909 to rotate.

[0045] Working principle: When stamping, the electric push rod 501 is used to drive the protective cover 5 to move up for stamping protection. After the stamping is completed and the stamped parts are removed, the protective cover 5 is continued to be driven to move up. Then the motor 601 is used to drive the connecting rod group 6, so that the connecting rod group 6 drives the adjustment seat 7 to move between the stamping seat and the base.

[0046] Then, the air pump 503 is used to inject high-pressure air into the hose 702, and then the air is injected into the air guide groove 701 through the hose 702, and then injected into the rotating tube 805 through the air guide port 806, and then ejected through the nozzle 807. At the same time, the high-pressure air passing through the air guide groove 701 drives the impeller 801 to rotate, so that the impeller 801 can drive the connected driving wheel 802 to rotate, so that the driving wheel 802 drives the transmission wheel 803 to rotate, and then the transmission wheel 803 drives the rotating tube 805 connected to the driven wheel 804 to rotate, so that the air ejected from the nozzle 807 cleans and maintains the stamping seat and the base;

[0047] The air for cleaning and maintenance is injected into the filter seat 9 through the air inlet pipe 903 and filtered through the filter screen 906. After the cleaning and maintenance is completed, the adjusting seat 7 is retracted by the connecting rod group 6. At this time, under the action of the tension spring 705, the conduit ring 703 connected to the slider 704 moves, and the hose 702 is bent and stored;

[0048] Then when the protective cover 5 moves downward, the adjusting wheel 910 will be driven to rotate through the connected adjusting rack 502, so that the adjusting wheel 910 drives the connected rotating rod 908 to rotate, and then the rotating rod 908 can drive the worm 909 to rotate, so that the worm 909 can drive the rotating shaft 904 connected to the worm wheel 907 to rotate, so that the rotating shaft 904 can drive the connected cover plate 905 to move, so that the cover plate 905 is removed, and then the filter screen 906 on the cover plate 905 can push the filtered metal chips through the collecting port 901 into the receiving seat 902 for collection.
