Description

A porous flexible robotic punching device Technical Field

[0001] This utility model relates to a multi-hole flexible robot punching device, belonging to the field of punching technology. Background Technology

[0002] Chinese patent CN220550377U discloses a high-efficiency punching device for flexible materials. It uses a cylinder to drive a punching die, and a power-accumulating lever and a power-accumulating device stop provide stronger power to the punching die, allowing for faster and more thorough punching of the flexible material. However, this device has drawbacks. The reciprocating motion of the cylinder and the disengagement of the power-accumulating lever's bearing from the power-accumulating device stop both generate significant noise, polluting the environment. Prolonged work in this environment can damage the hearing of workers. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a multi-hole flexible robot punching device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a multi-hole flexible robot punching device, comprising an upper template, a lower template, and several punches, wherein the upper template and the lower template are arranged opposite each other, and the several punches are connected to the lower surface of the upper template; the multi-hole flexible robot punching device further comprises a robot arm, a motor, a coupling, a pair of rotating seats, a rotating shaft, an eccentric wheel, a bearing, a punch rod, a pressure plate, a first spring, and an inertia wheel; the robot arm is connected to the motor, the output shaft of the motor is connected to the rotating shaft through the coupling, the two ends of the rotating shaft are respectively rotatably connected to the robot arm through a pair of rotating seats, the middle part of the rotating shaft is fixedly connected to the eccentric part of the eccentric wheel, and the eccentric wheel is fixedly connected to the inner ring of the bearing; the punch rod passes through and slides through the robot arm, the top end is fixedly connected to the pressure plate, and the bottom end is fixedly connected to the upper template, the first spring is sleeved on the punch rod between the pressure plate and the robot arm; the end of the rotating shaft is connected to the inertia wheel.

[0005] The present invention is further configured such that: a protective sleeve is provided on the lower surface of the robot arm, and the punch passes through the protective sleeve.

[0006] The present invention is further configured such that the multi-hole flexible robot punching equipment includes an unwinding mechanism, a winding mechanism, a support column and a pair of side plates, the lower template is connected to the top of the support column, and a side plate is connected to both sides of the support column. The ends of the side plates are respectively provided with an unwinding mechanism and a winding mechanism.

[0007] The present invention is further configured such that: a limiting baffle is connected to each side of the lower template, and a PTFE gasket is fixedly connected to the middle; the pair of limiting baffles are parallel; and the PTFE gasket is disposed between the pair of limiting baffles.

[0008] The present invention is further configured such that: the die is in the shape of an inverted round cup, an inner tube is connected to the top wall of the die, a second spring and an ejector rod are provided in the inner tube, a pair of lifting lugs are provided on both sides of the middle part of the ejector rod, a cap is screwed to the lower end of the inner tube, a through hole is provided at the center of the cap, the ejector rod passes through the through hole, and the second spring pushes the ejector rod to move downwards towards the die until the lifting lugs are blocked by the cap.

[0009] Compared with existing technologies, the advantages of this invention are as follows: The motor drives the rotating shaft to rotate via a coupling. The rotating shaft drives the eccentric wheel and bearing to rotate. During rotation, it pushes the pressure plate and punch downwards. The punch moves downwards, driving the upper template and die to punch holes in the flexible material on the lower template. The bearing reduces the friction between the eccentric wheel and the pressure plate. Because the end of the rotating shaft is connected to an inertia wheel, the rotation speed of the rotating shaft and the movement speed of the punch are more uniform. This avoids the inability to completely break the flexible material due to rotational jamming. Since there is no cylinder, there is no violent collision, no loud noise, and no environmental pollution. Workers are more comfortable and healthier working in this environment for extended periods.

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0016] Referring to Figures 1-4, a multi-hole flexible robot punching device in this embodiment includes an upper template 13, a lower template 12, several punches 14, a robot arm 1, a motor 2, a coupling 3, a pair of rotating seats 4, a rotating shaft 6, an eccentric wheel 16, a bearing 5, a punch rod 7, a pressure plate 17, a first spring 18, and an inertia wheel 15. The upper template 13 and the lower template 12 are arranged vertically opposite each other, and the several punches 14 are connected to the lower surface of the upper template 13. The robot arm 1 is connected to the motor 2, and the output of the motor 2... The shaft is connected to the rotating shaft 6 via a coupling 3. The two ends of the rotating shaft 6 are rotatably connected to the robot arm 1 via a pair of rotating seats 4. The middle part of the rotating shaft 6 is fixedly connected to the eccentric part of the eccentric wheel 16. The eccentric wheel 16 is fixedly connected to the inner ring of the bearing 5. The punch 7 passes through and slides in the robot arm 1. The top end is fixedly connected to the pressure plate 17, and the bottom end is fixedly connected to the upper template 13. The first spring 18 is sleeved on the punch 7 between the pressure plate 17 and the robot arm 1. The end of the rotating shaft 6 is connected to the inertia wheel 15.

[0017] Motor 2 drives shaft 6 to rotate via coupling 3. Shaft 6 drives eccentric wheel 16 and bearing 5 to rotate. During rotation, it pushes pressure plate 17 and punch 7 downward. Punch 7 moves downward, driving upper template 13 and die 14 to punch holes in the flexible material on lower template 12. After punching, shaft 6 continues to rotate, driving bearing 5 upward via eccentric wheel 16. First spring 18 pushes pressure plate 17 and punch 7 upward, keeping pressure plate 17 in contact with bearing 5. Punch 7 moves upward, driving upper template 13 and die 14 to separate from lower template 12. Bearing 5 reduces friction between eccentric wheel 16 and pressure plate 17. Because inertia wheel 15 is connected to the end of shaft 6, the rotation speed of shaft 6 and the movement speed of punch 7 are more uniform, avoiding incomplete punching of flexible material due to rotational jamming. Since there is no cylinder, there is no violent collision, no loud noise, and no environmental pollution. Workers are more comfortable and healthier working in this environment for extended periods.

[0018] In order to keep the punch rod 7 moving in the vertical direction, the present invention is further configured such that: a sheath tube 19 is provided on the lower surface of the robot arm 1, and the punch rod 7 passes through the sheath tube 19.

[0019] To facilitate continuous punching, this invention further includes: the multi-hole flexible robotic punching device further comprises an unwinding mechanism 10, a winding mechanism 11, a support column 8, and a pair of side plates 9. The lower template 12 is connected to the top of the support column 8, and a side plate 9 is connected to both sides of the support column 8. The ends of the side plates 9 are respectively provided with the unwinding mechanism 10 and the winding mechanism 11. The unwinding mechanism 10 discharges flexible material, bypasses the lower template 12, and is wound up by the winding mechanism 11. The support column 8 provides support for the lower template 12, and the side plates 9 provide support for the unwinding mechanism 10 and the winding mechanism 11.

[0020] To prevent the flexible material from deviating on the lower template 12, this invention further comprises: a limiting baffle 27 connected to each side of the lower template 12, and a PTFE pad 28 fixedly connected to the middle; the pair of limiting baffles 27 are parallel; the PTFE pad 28 is positioned between the pair of limiting baffles 27. Since the height of the limiting baffles 27 exceeds the upper surface of the lower template 12, the flexible material can only pass through between the pair of limiting baffles 27. Due to the PTFE pad 28, which possesses superior elasticity, toughness, and strength, the punch 14 penetrates the flexible material and extends into the surface of the PTFE pad 28, completely severing the flexible material and preventing any lingering residue. Afterwards, the PTFE pad 28 springs back to its original shape.

[0021] After punching, a small amount of flexible material fragments become stuck inside the die 14. To expel these fragments, the present invention further comprises the following: the die 14 is shaped like an inverted cup, with an inner tube 21 connected to its top wall. A second spring 22 and an ejector rod 23 are installed within the inner tube 21. A pair of lifting lugs 25 are located on either side of the middle portion of the ejector rod 23. A cap 24 is screwed to the lower end of the inner tube 21, and a through hole 26 is located at the center of the cap 24. The ejector rod 23 passes through the through hole 26. The second spring 22 pushes the ejector rod 23 downwards towards the die 14 until the lifting lugs 25 are blocked by the cap 24. The bottom end of the ejector rod 23 is below the die 14. When the die 14 moves downwards, the bottom end of the ejector rod 23 first contacts the flexible material, causing the ejector rod 23 to retract into the inner tube 21, compressing the second spring 22. As the die 14 moves away from the lower die plate 12, the second spring 22 extends, pushing the ejector rod 23 out of the inner tube 21 until the lifting lug 25 is blocked by the cover 24, ejecting the flexible fragment from the die 14.

[0022] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
