Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a laser cutting path optimization and positioning mechanism for hardware tools. Background Technology

[0002] Laser cutting path optimization and positioning mechanisms for hardware tools are widely used in various hardware tool manufacturing enterprises, including those producing general cutting tools, CNC tools, and woodworking tools. They are suitable for cutting various materials, such as high-speed steel, cemented carbide, and stainless steel. In tool production in industries such as automotive manufacturing, machining, and electronic equipment manufacturing, this mechanism can meet the demands for high-precision and high-efficiency cutting, improve tool quality and performance, and reduce production costs, demonstrating significant application value. The main purpose of these mechanisms is to accurately position the tool during laser cutting of hardware tools and optimize the cutting path to improve cutting accuracy, efficiency, and quality, while reducing costs. To reduce material waste and production costs, optical devices such as laser rangefinders and vision recognition systems are used to accurately measure and position the tool blank. The laser rangefinder can measure the distance between the tool and the cutting head in real time, so that the height of the cutting head can be adjusted according to the thickness and shape of the tool, ensuring that the cutting focus is always on the tool surface and improving cutting quality. The vision recognition system can acquire image information of the tool blank through a camera, compare it with a preset model, and accurately identify the contour and position of the tool, thereby achieving automatic positioning and path planning. For example, when cutting tools with complex shapes, the vision recognition system can quickly and accurately identify the edges and feature points of the tool, providing accurate positioning information for laser cutting.

[0003] Existing laser cutting optimization methods generally rely on intelligent algorithms for path optimization. However, dust generated during laser cutting inevitably obstructs the lens, affecting the optical positioning and tool capture, and thus impacting the accuracy of laser cutting. Therefore, this paper proposes a laser cutting path optimization and positioning mechanism for hardware tools to address these issues. Utility Model Content

The feeding mechanism is fixedly connected to the top of the laser cutting table. The optical positioning laser cutting mechanism is located to the right of the feeding mechanism at the top of the laser cutting table.

[0009] Preferably, the suction pipe, HEPA filter and suction fan are a set, and there are three sets in total, which are evenly spaced above the collection box. The width of the bottom opening of the suction pipe matches the width of the limiting groove.

[0010] Preferably, the cross-section of the guide block is a right triangle, and the length of the guide block matches the length of the collection groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the components such as the collection tank, protective net, guide block, suction pipe, HEPA filter, suction fan, collection box, and protective cover are provided. The protective cover can isolate external dust while preventing internal dust from spreading, facilitating dust entry into the collection tank. The suction fan, suction pipe, and collection tank can directly suck the dust generated during cutting into the collection box, preventing dust from drifting and obstructing the lens of the optical positioning laser cutting mechanism, thus affecting the cutting accuracy. This solves the problem that existing laser cutting optimization generally relies on intelligent algorithms for path optimization, and the dust generated during laser cutting inevitably obstructs the lens, affecting the optical positioning and capture of the tool, and thus affecting the laser cutting accuracy.

[0013] 2. In this utility model, the rubber layer can enhance the sealing between the protective cover and the feeding mechanism, the observation window can facilitate the observation of the internal situation when the protective cover is in place, and the guide block can facilitate the airflow, so that dust and debris can accurately enter the collection box through the dust suction pipe.

[0023] A laser cutting path optimization and positioning mechanism for hardware tools includes a laser cutting table 1, a feeding mechanism 2, and an optical positioning laser cutting mechanism 3. The feeding mechanism 2 is fixedly connected to the top of the laser cutting table 1. The optical positioning laser cutting mechanism 3 is located to the right of the feeding mechanism 2 at the top of the laser cutting table 1. A collection groove 4 is opened at the top of the laser cutting table 1 between the feeding mechanism 2 and the optical positioning laser cutting mechanism 3. A protective net 5 is fixedly connected inside the collection groove 4. A guide block 6 located below the protective net 5 is fixedly connected inside the collection groove 4. Three dust suction pipes 7 are fixedly connected at intervals inside the laser cutting table 1. A HEPA filter 8 is fixedly connected inside the dust suction pipes 7. A vacuum fan 9 located to the right of the HEPA filter 8 is fixedly connected to the right side of the tube 7. A limiting groove 10 located below the vacuum tube 7 is opened inside the laser cutting table 1. A collection box 11 is provided inside the limiting groove 10. A handle 12 is fixedly connected to the front side of the collection box 11. Hydraulic rods 13 located on both sides of the feeding mechanism 2 and the optical positioning laser cutting mechanism 3 are fixedly connected inside the laser cutting table 1. A protective cover 14 is fixedly connected to the top of the hydraulic rod 13. A rubber layer 15 is provided on the left side of the protective cover 14. Observation windows 16 are provided on both sides of the protective cover 14. A connecting frame 17 located outside the feeding mechanism 2, the optical positioning laser cutting mechanism 3 and the protective net 5 is fixedly connected to the top of the laser cutting table 1.

[0024] The outer dimensions of the connecting frame 17 match the inner dimensions of the protective cover 14, and the outer shape of the connecting frame 17 matches the inner shape of the protective cover 14, which helps to improve the connection between the protective cover 14 and the laser cutting table 1; the left notch of the connecting frame 17 fits into both sides of the feeding mechanism 2, the inner shape of the rubber layer 15 matches the shape of the feeding mechanism 2, and the inner dimensions of the rubber layer 15 match the outer dimensions of the feeding mechanism 2. The rubber layer 15 can improve the sealing effect between the feeding mechanism 2 and the protective cover 14; dust suction pipe 7, The HEPA filter 8 and the vacuum fan 9 are grouped together, with a total of three groups, and are evenly spaced above the collection box 11. The width of the bottom opening of the vacuum pipe 7 matches the width of the limiting groove 10.

The larger protective net 5 can prevent the tool from falling into the collection groove 4 after cutting, while ensuring that dust and debris enter. After being guided by the guide block 6, they enter the suction pipe 7 and fall into the collection box 11 under the action of gravity. The HEPA filter 8 can prevent debris and dust from passing through, while allowing normal air circulation to ensure the suction power of the dust extraction fan 9.
