Description

Technical Field

[0001] The utility model belongs to the technical field of metal cutting tooling, and in particular relates to a manipulator positioning head cutting machine. Background Art

[0002] Wire mesh is widely used in the petroleum, hardware, chemical, construction, and machinery industries. Wire mesh production processes can be categorized into weaving, spot welding, cutting, and stamping types, with spot welding being 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 grabs the wire mesh and feeds it under a cutter for cutting, ordinary robotic arms are not precise, lack a vision system, and cannot self-adjust. They cannot guarantee that the wire mesh will be delivered to the intended position, resulting in millimeter-level errors and, therefore, inability to guarantee cutting accuracy. High-precision robotic arms are very expensive, significantly increasing production costs. Summary of the Invention

[0003] In view of the defects of the above-mentioned prior art, the purpose of the present invention is to provide a manipulator positioning head cutting machine, which is used for auxiliary adjustment of the manipulator, can adjust and position the wire frame, and ensure cutting accuracy.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a manipulator positioning and cutting machine, including a manipulator positioning plate, a sliding positioning plate and a motor, a sliding positioning plate is slidably connected below the manipulator positioning plate of the manipulator, the motor is fixed on the manipulator, and the output end of the motor is connected to the sliding positioning plate, and the linear displacement output by the motor drives the sliding positioning plate to slide along the slide groove of the manipulator positioning plate, and a clamping claw for grabbing the wire mesh is connected below the sliding positioning plate; an in-position detection switch for detecting the position of the wire mesh is provided on the cutting station of the cutting machine.

[0005] Based on the above technical solution, it should be noted that the utility model is an auxiliary tooling used in conjunction with a manipulator. The mobile loading function is realized by the manipulator itself. The manipulator positioning plate is the location for installing the gripper of the manipulator. It is a structural design that comes with the manipulator. The manipulator selected is a Bronte manipulator.

[0006] Furthermore, the motor housing is connected to the manipulator positioning plate by bolts.

[0007] Furthermore, the motor is a stepping motor.

[0015] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] See attached Figure 1-3 A manipulator positioning and cutting machine includes a manipulator positioning disk 1, a sliding positioning disk 2 and a stepper motor 3. The sliding positioning disk 2 is slidably connected to the bottom of the manipulator positioning disk 1 of the manipulator. The stepper motor 3 is connected to the manipulator positioning disk 1 by bolts. The output end of the stepper motor 3 is connected to the sliding positioning disk 2. The linear displacement output by the stepper motor 3 drives the sliding positioning disk 2 to slide along the slide groove of the manipulator positioning disk 1. A pneumatic clamp 4 for grabbing wire mesh is connected below the sliding positioning disk 2, which is driven by a high-pressure air source to grab and release the wire mesh 5; an in-position detection switch 6 for detecting the position of the wire mesh is provided on the cutting station.

[0017] Based on the above technical solution, it should be noted that the present invention is an auxiliary tooling for use with a manipulator. The manipulator's own moving and loading functions are implemented. The manipulator's positioning plate 1 serves as the location for the manipulator's gripper, a structural design inherent to the manipulator. The manipulator is a Bronte manipulator. A stepper motor is used for high precision and fast response, enabling fine-tuning of the position of the sliding positioning plate 2 to compensate for millimeter-level errors in the manipulator. Because the manipulator lacks a visual system and cannot determine whether the wire mesh has reached the predetermined cutting position, a position detection switch 6 is provided at the cutting position to monitor the wire mesh's position. The position detection switch is connected to the stepper motor via a PLC. When the position detection switch detects that the wire mesh has reached the predetermined cutting position, it sends a signal to the stepper motor 3, causing the stepper motor 3 to stop outputting linear displacement. The cutter is then pneumatically driven to press down and cut the end of the wire mesh. During the cutting process, the wire mesh is always clamped in the manipulator's pneumatic gripper. After cutting is completed, the manipulator transfers the wire mesh to the next process or storage location. To ensure that the in-place detection switch is not interfered with, when the robot is programmed, after the robot completes loading, the wire mesh frame is separated from the cropping station by a horizontal distance. This horizontal distance is controlled by the sliding positioning plate. This means that the robot performs coarse adjustment of the feeding position, while the sliding positioning plate performs fine adjustment of the feeding position. This prevents the robot from directly delivering the wire mesh frame to the cropping station. If there is an error in the wire mesh frame's position (for example, the feeding position exceeds the predetermined position), it can still be detected by the in-place detection switch, rendering the in-place detection switch ineffective and preventing the sliding positioning plate from fine-tuning the feeding position.

[0018] Furthermore, the slide groove of the manipulator positioning plate 1 is a T-shaped slide groove 1.1, and the sliding positioning plate is slidably connected to the manipulator positioning plate through the T-shaped slide groove. The T-shaped slide groove 1.1 is arranged in parallel with at least two groups, and the T-shaped slide groove has high precision and good guiding performance.

[0019] Furthermore, the pneumatic clamping jaws 4 include a cylinder seat 4.1, a slide 4.2 and a clamping jaw 4.3. The cylinder seat 4.1 is fixed below the sliding positioning plate 2. The cylinder seat 4.1 controls the two slides to slide in opposite directions or towards each other through a high-pressure air source. A clamping jaw 4.3 is fixedly connected below each slide. The two clamping jaws 4.3 clamp the wire mesh on the opposite sides or opposite sides of the two parallel sides. See the attached Figure 2 .

[0020] Furthermore, the clamping claws 4.3 are arranged in a stepped shape, and the bottom edge of the clamping claws 4.3 is arranged in a horizontal direction. The bottom edge of the clamping claws 4.3 is located below the wire mesh to support the wire mesh.

[0021] Furthermore, two clamping claws 4.3 are connected to the bottom of each slide 4.2. The two clamping claws 4.3 are symmetrically arranged in the stepped extension direction. The two clamping claws 4.3 are respectively used to clamp on the opposite sides and the back sides of the two parallel sides of the wire mesh. Figure 3 .
