Description

Technical Field

[0001] This invention belongs to the field of metal cutting and processing tooling technology, specifically relating to a robotic arm-loaded head cutting machine. Background Technology

[0002] Wire mesh has wide applications in petroleum, hardware, chemical, construction, and machinery industries. According to the production process, wire mesh can be divided into woven, spot-welded, cut-and-stretched, and stamped types, among which spot-welded is the most common. Before spot welding, the wires must be arranged in a wire frame, and after spot welding, the excess ends of the wires must be removed. When a robotic arm picks up the wire mesh and feeds it to the cutting station for cutting, the following problems arise because ordinary robotic arms have low precision, lack a vision system, and cannot self-adjust: First, the robotic arm picks up the wire mesh at a fixed position and angle for feeding. The placement of the wire mesh does not affect the robotic arm's gripping. However, if the wire mesh is placed at an angle that is skewed before gripping, the robotic arm cannot align the wire mesh during gripping. This skewed angle affects the cutting accuracy when the robotic arm holds the wire mesh for cutting. If the robotic arm releases itself before the wire mesh is fed into the cutting station, and the angle and position of the wire mesh are adjusted manually before the robotic arm re-grabs the wire mesh and feeds it into the cutting station, cutting accuracy can be guaranteed, but the processing pace is slow and efficiency is low. Secondly, because the wire mesh sheets are stacked, and because they are relatively thin and have a hollow structure, the robotic arm often grasps more than one sheet at a time, disrupting the processing rhythm and affecting the cutting operation. Thirdly, when the robotic arm grips the wire mesh and feeds it into the cutting station, there will be a millimeter-level error between the wire mesh's position and the intended cutting station position, thus compromising cutting accuracy. Summary of the Invention

[0003] In view of the defects of the prior art, the purpose of the present invention is to provide a robotic arm positioning and cutting machine for auxiliary adjustment of the robotic arm, which can adjust and position the wire frame before and after the robotic arm grasps the wire, so as to ensure the cutting accuracy.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a wire mesh feeding and cutting machine for robotic arms, comprising a wire mesh flipping mechanism before the robotic arm grasps the mesh and a wire mesh displacement mechanism during the robotic arm's grasping state; the wire mesh flipping mechanism includes a magnetic chuck and a flipping arm, the magnetic chuck magnetically attracts the wire mesh, the magnetic chuck is fixedly connected to the flipping arm, the flipping arm is connected to a flipping drive mechanism, the flipping drive mechanism drives the flipping arm and the magnetic chuck to flip, and the magnetic chuck has an adjustment groove for adjusting the posture of the wire mesh, the shape of the adjustment groove being adapted to the outer contour of the wire mesh. The adjustment groove has a slope, and the inner surface of the adjustment groove forms a slope with a wide opening and a narrow bottom. The wire mesh displacement mechanism is mounted on the robot arm. The wire mesh displacement mechanism includes a sliding positioning plate and a motor. The sliding positioning plate is slidably connected below the robot arm's positioning plate. The motor is fixed to the robot arm, and the output end of the motor is connected to the sliding positioning plate. The linear displacement output by the motor drives the sliding positioning plate to slide along the sliding groove of the robot arm's positioning plate. A gripper for grasping the wire mesh is connected below the sliding positioning plate. An arrival detection switch for detecting the position of the wire mesh is set on the cutting station of the cutting machine.

[0005] Based on the above technical solution, it should be noted that the present invention is an auxiliary tooling used in conjunction with a robotic arm. The moving and feeding function is realized by the robotic arm itself. The positioning plate of the robotic arm is the position where the gripper of the robotic arm is installed. It is a structural design that comes with the robotic arm. The robotic arm selected is the Borunte robotic arm.

[0006] Furthermore, several wire mesh sheets awaiting loading are stacked on a storage platform, and a lifting device for controlling the lifting and lowering of the storage platform is provided below the storage platform; the magnetic chuck is flipped to the top of the storage platform by a flipping arm, and the adjustment slot of the magnetic chuck faces downward to attract the wire mesh sheet located at the top of the storage platform; the magnetic chuck is flipped to the loading station by a flipping arm, and the adjustment slot of the magnetic chuck faces upward to attract a wire mesh sheet; the gripper of the robot arm grabs the wire mesh sheet from the magnetic chuck at the loading station.

[0007] Furthermore, the bottom of the adjustment groove is provided with several magnetic points formed by magnets, and the magnetic chuck attracts the wire mesh through these magnetic points.

[0008] Furthermore, the flipping drive mechanism is a cylinder or a hydraulic cylinder. The output end of the flipping drive mechanism is connected to the rotating shaft, one end of the flipping arm is fixedly connected to the rotating shaft, and the other end of the flipping arm is fixedly connected to the magnetic chuck. The angular displacement output by the flipping drive mechanism drives the rotating shaft to rotate back and forth, thereby causing the flipping arm and the magnetic chuck to flip.

[0009] Furthermore, bearings and bearing housings are sequentially fitted onto both ends of the rotating shaft.

[0010] Furthermore, the motor housing is bolted to the positioning plate of the robotic arm.

[0011] Furthermore, the motor is a stepper motor.

[0012] Furthermore, the robotic arm positioning disk is provided with several parallel T-shaped grooves, and the sliding positioning disk is slidably connected to the robotic arm positioning disk through several T-shaped grooves.

[0013] Furthermore, the gripper is a pneumatic gripper, which is driven by a high-pressure air source to grip and release the wire mesh.

[0014] The beneficial effects of this invention are as follows: The wire mesh flipping mechanism separates stacked wire mesh sheets one by one using a magnetic disk for gripping by a robotic arm, ensuring that the robotic arm grasps only one wire mesh sheet at a time. When the magnetic disk attracts the wire mesh sheet, it adjusts the posture of the wire mesh sheet via an adjustment groove, ensuring the consistency of the angle and position of the wire mesh sheet to be grasped before the robotic arm grasps it, avoiding the need for readjustment and alignment before cutting the wire mesh sheet. The wire mesh sheet displacement mechanism mounts a sliding positioning disk and a motor on the robotic arm. The motor controls the displacement of the sliding positioning disk, achieving fine-tuning of the gripper position. A positioning detection switch monitors the positioning of the wire mesh sheet, ensuring the cutting accuracy of the wire mesh sheet end. Attached Figure Description

[0016] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] See appendix Figure 1-4 A robotic arm-operated wire mesh cutting machine includes a wire mesh flipping mechanism before the robotic arm grasps the wire mesh and a wire mesh displacement mechanism during the robotic arm's grasping state. The wire mesh flipping mechanism includes a magnetic chuck 1 and a flipping arm 2. The magnetic chuck 1 magnetically attracts the wire mesh 5 and is fixedly connected to the flipping arm 2. The flipping arm 2 is connected to a flipping drive mechanism, which drives the flipping arm 2 and the magnetic chuck 1 to flip. The magnetic chuck 1 has an adjustment groove 1.1 for adjusting the posture of the wire mesh. The shape of the adjustment groove 1.1 matches the outer contour of the wire mesh 5. The adjustment groove 1.1 has a slope, with the inner surface of the groove having a wide opening and a narrow bottom. The wire mesh displacement mechanism is mounted on the robotic arm. The mechanism includes a sliding positioning disk 10 and a stepper motor 11. The sliding positioning disk 10 is slidably connected below the robotic arm positioning disk 9. The stepper motor 11 is bolted to the robotic arm positioning disk 9. The output end of the stepper motor 11 is connected to the sliding positioning disk 10. The linear displacement output by the stepper motor 11 drives the sliding positioning disk 10 to slide along the groove of the robotic arm positioning disk 9. A pneumatic gripper 12 for gripping the wire mesh is connected below the sliding positioning disk 10. The wire mesh 5 is gripped and released using a high-pressure air source. A position detection switch 13 for detecting the position of the wire mesh is installed at the cutting station.

[0018] Based on the above technical solution, it should be noted that the robotic arm feeding and cutting machine of this invention is an auxiliary tooling used in conjunction with the robotic arm. The moving feeding function is realized by the robotic arm itself. The robotic arm positioning disk 9 in the wire mesh displacement mechanism is the position for mounting the gripper of the robotic arm, which is a structural design inherent to the robotic arm. The robotic arm selected is a Borunte robotic arm. The motor is a stepper motor, which has high precision and fast response speed, and can realize fine adjustment of the position of the sliding positioning disk 10, compensating for millimeter-level errors on the robotic arm. Since the robotic arm lacks a vision system, it cannot determine whether the wire mesh has reached the predetermined cutting position. Therefore, a position detection switch 13 is installed at the cutting position to monitor the wire mesh's arrival. This switch is connected to a stepper motor via a PLC. When the switch detects that the wire mesh has reached the predetermined cutting position, it sends a signal to the stepper motor 11. The stepper motor 11 stops outputting linear displacement, and then the cutter, pneumatically driven, presses down to cut the end of the wire mesh. During the cutting process, the wire mesh remains clamped in the robotic arm's pneumatic gripper. After cutting, the robotic arm places the wire mesh into the next process or placement position. To ensure the position detection switch is not interfered with, the robotic arm is programmed so that after the loading action, the wire mesh frame is separated from the cutting position by a horizontal distance. This horizontal distance is controlled by a sliding positioning plate, allowing for coarse adjustment of the feeding position by the robotic arm and fine adjustment by the sliding positioning plate. To prevent the robotic arm from directly sending the wire mesh frame to the cutting station, the position of the wire mesh frame is still detected by the positioning detection switch when there is an error (such as the feeding position is beyond the predetermined position). If the positioning detection switch fails, the sliding positioning plate cannot be controlled for fine adjustment.

[0019] The adjustment groove 1.1 of the wire mesh flipping mechanism has a slope, which enables the wire mesh in the groove to self-adjust and align. At the same time, it can reserve a certain space under the wire mesh in the adjustment groove for the robot to grasp. Since the edge of the wire mesh is attached to the inner surface of the adjustment groove, the robot grasps the mesh wire in the wire mesh.

[0020] Furthermore, several wire mesh sheets 5 awaiting loading are stacked on the storage platform 7. A lifting device 8 for controlling the lifting and lowering of the storage platform 7 is provided below the storage platform 7. The magnetic chuck 1 is flipped to the top of the storage platform 7 by the flipping arm 2. The opening of the adjustment groove 1.1 of the magnetic chuck 1 faces downward and adsorbs the wire mesh sheet located at the top of the storage platform. The magnetic chuck 1 is flipped to the loading station by the flipping arm 2. The opening of the adjustment groove 1.1 of the magnetic chuck faces upward and adsorbs a wire mesh sheet. The pneumatic gripper of the robot arm grabs the wire mesh sheet 5 from the magnetic chuck 1 at the loading station.

[0021] Based on the above technical solution, the wire mesh sheets are initially stacked on the storage platform 7, resulting in minimal deviation in the placement angle. This allows for self-adjustment and alignment via the slope of the adjustment groove 1.1 upon entry. The magnetic chuck 1 maintains a fixed height above the storage platform 7 each time it flips. Therefore, the storage platform 7 uses a lifting device 8 to adjust the height of the top wire mesh sheet for magnetic chuck 1 to adhere. The lifting device 8 can be of various types, such as scissor lift, telescopic lift, sleeve lift, or threaded lift, as long as it enables controllable lifting of the storage platform 7.

[0022] Furthermore, the bottom of the adjustment groove 1.1 is provided with several magnetic points formed by magnets, and the magnetic chuck attracts the wire mesh through these magnetic points.

[0023] Based on the above technical solution, the magnetic chuck 1 is equipped with several magnetic points. The wire mesh is attracted by these magnetic points. The magnetic force of the magnetic points is relatively small. When the flipping arm 2 flips to its position, the vibration generated can momentarily separate the wire mesh 5 from the magnetic chuck 1, allowing the wire mesh 5 to be adjusted and corrected in the adjustment groove 1.1. At the same time, the low magnetic force of the magnetic points does not affect the robot arm's ability to grasp the wire mesh in the magnetic chuck.

[0024] In another embodiment, the magnetic chuck 1 is electromagnetically controlled. When the flipping arm flips to the top of the storage platform to adsorb the wire mesh and during the flipping process, the magnetic chuck is energized and magnetized. When the flipping arm flips to the loading station, the magnetic chuck is de-energized and demagnetized. The wire mesh is adjusted and corrected in the adjustment groove, and the robot arm grabs the wire mesh in the magnetic chuck.

[0025] Furthermore, the flipping drive mechanism 3 is a cylinder or a hydraulic cylinder. The output end of the flipping drive mechanism 3 is connected to the rotating shaft 4. One end of the flipping arm 2 is fixedly connected to the rotating shaft 4, and the other end of the flipping arm 2 is fixedly connected to the magnetic chuck 1. The angular displacement output by the flipping drive mechanism 3 drives the rotating shaft 4 to rotate back and forth, thereby causing the flipping arm 2 and the magnetic chuck 1 to flip.

[0026] Based on the above technical solutions, when the tilting drive mechanism 3 is a hydraulic cylinder, a rack and pinion swing cylinder is selected. The working principle of the rack and pinion swing cylinder is that hydraulic oil drives the rack to reciprocate, which in turn drives the gear, which serves as the output shaft, to rotate and output. The gear is fixedly connected to the shaft, causing the shaft to swing back and forth. When the tilting drive mechanism is a pneumatic cylinder, a swing cylinder (rotary cylinder) is selected. It also adopts the rack and pinion principle, using a high-pressure air source to drive the rack to reciprocate, which in turn drives the gear, which serves as the output shaft, to rotate and output. The gear is fixedly connected to the shaft, causing the shaft to swing back and forth. In addition to pneumatic and hydraulic cylinders, the tilting drive mechanism can also use a stepper motor to output angular displacement.

[0027] Furthermore, in order to install the rotating shaft 4, bearings and bearing seats 6 are sequentially fitted at both ends of the rotating shaft.

[0028] Furthermore, the sliding groove of the robotic arm positioning disk 9 is a T-shaped sliding groove 9.1, and the sliding positioning disk 10 is slidably connected to the robotic arm positioning disk through the T-shaped sliding groove. At least two sets of the T-shaped sliding grooves 9.1 are arranged in parallel, and the T-shaped sliding grooves have high precision and good guiding properties.

[0029] Furthermore, the pneumatic gripper 12 includes a cylinder seat 12.1, a slide 12.2, and a gripping claw 12.3. The cylinder seat 12.1 is fixed below the sliding positioning plate 10. The two slides are controlled by a high-pressure air source to slide back and forth or towards each other. A gripping claw 12.3 is fixedly connected below each slide. The two gripping claws 12.3 clamp the wire mesh on opposite sides or back and forth sides of two parallel edges.

[0030] Furthermore, the clamping claw 12.3 is arranged in a stepped manner, with the bottom edge of the clamping claw 12.3 arranged horizontally, and the bottom edge of the clamping claw 12.3 is located below the wire mesh to support the wire mesh.

[0031] Furthermore, each slide 12.2 is connected to two clamping claws 12.3 below it. The two clamping claws 12.3 are symmetrically arranged with a stepped extension direction. The two clamping claws 12.3 are used to clamp the wire mesh on the opposite sides and back sides of two parallel edges, respectively. See Appendix. Figure 3 .

[0032] When the robotic arm is loading, the rotating shaft 4 rotates, and the magnetic chuck 1 is flipped by the flipping arm 2 to the top of the storage platform 7 to attract the wire mesh sheet located at the top of the storage platform. Then, the rotating shaft 4 rotates back, driving the flipping arm 2, the magnetic chuck 1, and one of the wire mesh sheets in the magnetic chuck 1 to flip to the loading station. The pneumatic gripper 12 of the robotic arm grabs the wire mesh sheet 5 from the magnetic chuck 1 at the loading station. The robotic arm clamps the wire mesh sheet and sends it to the front of the cutting station of the cutting machine. The stepper motor 11 is started, and the stepper motor 11 pushes the sliding positioning plate 10 to send the wire mesh sheet to the cutting station. When the arrival detection switch detects that the wire mesh sheet has reached the predetermined cutting station, it sends a signal to the stepper motor 3. The stepper motor 3 stops outputting linear displacement, and then the cutter is pneumatically driven to press down and cut the end of the wire mesh sheet. During the cutting process, the wire mesh sheet is always clamped in the pneumatic gripper of the robotic arm. After the cutting is completed, the robotic arm puts the wire mesh sheet into the next process or placement position. This invention can adjust and position the wire frame before and during the gripping process by the robotic arm, ensuring the cutting accuracy.
