Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a high-precision omnidirectional vision positioning and control system based on laser cutting. Background Technology

[0002] When laser cutting machines cut sheet metal, the cutting area is typically monitored by a camera to ensure precise positioning and control of the cutting head. Traditional cutting machines use fixed cameras to monitor the cutting head from a fixed height and angle. This prevents operators from monitoring the cutting head from different heights and angles, resulting in low accuracy in position monitoring. Therefore, it is essential to install a comprehensive monitoring device on the outside of the cutting head.

[0003] Traditional methods for monitoring the cutting head of laser cutting machines typically use fixed cameras to monitor the cutting head and the cutting area. This method cannot change the camera's height or monitor the camera from different heights and angles, resulting in low monitoring accuracy. Therefore, a high-precision omnidirectional vision positioning control system based on laser cutting is needed to solve this problem. Summary of the Invention

[0004] One objective of this application is to provide a high-precision omnidirectional vision positioning control system based on laser cutting, which can solve the technical problem that existing high-precision omnidirectional vision positioning control systems based on laser cutting are not convenient for monitoring the cutting head and cutting parts of the cutting machine at different heights and from different angles.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-precision omnidirectional vision positioning control system based on laser cutting, comprising a first cylinder, a first lifting frame and a rotating plate, wherein the output end of the first cylinder is equipped with the first lifting frame, a plurality of first mounting rods are symmetrically mounted on the bottom of the first lifting frame, the rotating plate is movably mounted through the inner side of the first mounting rods, and a camera is mounted on the top of the rotating plate;

[0006] The top of the first lifting frame is equipped with multiple second cylinders, and the output end of the second cylinder is equipped with a second lifting frame.

[0007] Preferably, a connecting plate is installed on the top of the first cylinder.

[0008] Preferably, the first lifting frame is a square ring, so as to surround the outside of the cutting head of the cutting machine.

[0009] Preferably, the rotating plate can rotate up and down to allow the camera to adjust its tilt angle up and down, and the cameras are symmetrically distributed on all four sides at the bottom of the first lifting frame.

[0010] Preferably, a plurality of second mounting rods are symmetrically installed on the inner side of the second lifting frame, a mounting frame is installed at one end of the second mounting rod, a transparent plate is movably installed through the top of the mounting frame, and a first threaded rod is installed through the front of the mounting frame.

[0011] Preferably, a mounting block is installed on the top of the first lifting frame, and a second threaded rod is installed through one side of the mounting block.

[0012] Preferably, a lifting rod is movably mounted through the top of the mounting block, and a handle is mounted on one side of the lifting rod.

[0013] Preferably, a third lifting frame is installed at one end of the lifting rod, and multiple wiping cloths are symmetrically installed on the outer side of the third lifting frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention uses a first cylinder to move a first lifting frame up and down, thereby changing the height of the first lifting frame and consequently moving a camera up and down. The camera can monitor the cutting head from different heights. Simultaneously, a second cylinder moves a second lifting frame up and down, causing the rotating plate to rotate up and down. This allows the camera on the rotating plate to change its tilt angle, enabling the camera to monitor the cutting head of the cutting machine from different tilt angles at different heights. This results in more comprehensive monitoring of the cutting head.

This allows the camera on the rotating plate to change its tilt angle, enabling the camera to monitor the cutting head of the cutting machine from different tilt angles at different heights. This results in more comprehensive monitoring of the cutting head.

[0016] 2. This invention protects the camera by using a transparent plate, preventing dust generated during cutting from directly falling onto the camera and affecting its shooting performance. Furthermore, rotating the first threaded rod in the opposite direction releases the transparent plate, facilitating the removal and replacement of any damaged sections. This allows the high-precision omnidirectional vision positioning control system based on laser cutting to protect the camera by using a transparent plate, preventing dust generated during cutting from directly falling onto the camera and affecting its shooting performance. Additionally, rotating the first threaded rod in the opposite direction releases the transparent plate, facilitating the removal and replacement of any damaged sections.

[0017] 3. When dust covers the transparent plate and affects the camera's shooting effect, the present invention allows the user to move the lifting rod up and down by holding the handle, thereby moving the third lifting frame up and down. As the third lifting frame moves up and down, a wiping cloth can be used to wipe the surface of the transparent plate, removing the dust and preventing it from affecting the camera's shooting effect. This ensures the clarity of the camera's monitoring of the cutting head. This invention enables the high-precision omnidirectional vision positioning control system based on laser cutting to achieve the same effect. Attached Figure Description

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The present invention provides an embodiment of a high-precision omnidirectional vision positioning control system based on laser cutting;

[0031] The device includes a first cylinder 1, a first lifting frame 2, and a rotating plate 3. A connecting plate 101 is mounted on the top of the first cylinder 1. The first cylinder 1 converts pneumatic energy into kinetic energy, driving a piston rod to move up and down. The piston rod then drives the first lifting frame 2 to move up and down, allowing the camera 301 on the first lifting frame 2 to change height. This enables the camera 301 to monitor the cutting head and cutting area of ​​the cutting machine from different heights. The connecting plate 101 connects the device to the cutting machine. The connecting plate 101 can be connected to the cutting machine components via screws through holes drilled in it. The connecting plate 101 can be installed on the mounting components of the cutting head of the cutting machine for easy... Simultaneously, the first lifting frame 2 can surround the outside of the cutting head of the cutting machine, allowing multiple cameras 301 to surround the four sides of the cutting head. This facilitates comprehensive monitoring of the cutting head by multiple cameras 301, resulting in higher monitoring accuracy. The output end of the first cylinder 1 is equipped with the first lifting frame 2, and multiple first mounting rods 201 are symmetrically installed at the bottom of the first lifting frame 2. The first lifting frame 2 is a square ring, designed to surround the outside of the cutting head of the cutting machine. This arrangement allows multiple cameras 301 to monitor the cutting head from all angles. The first lifting frame 2 provides mounting positions for the first mounting rods 201, enabling the first mounting rods to... The mounting rod 201 has a designated mounting position. The first lifting frame 2 can move the camera 301 up and down by moving it up and down, changing the height of the camera 301. This allows the camera 301 to be aligned with the cutting head inside the first lifting frame 2 when the tilt angle of the rotating plate 3 changes, facilitating monitoring of the cutting head from different tilt angles. The first mounting rod 201 is symmetrically arranged inside the first lifting frame 2. The first mounting rod 201 serves to mount the rotating plate 3, providing a position for its installation. The rotating plate 3 is movably mounted through the inner side of the first mounting rod 201. The camera 301 is mounted on the top of the rotating plate 3. The rotating plate 3 can rotate up and down to facilitate camera movement. The camera 301 can be tilted up and down. The camera 301 is symmetrically distributed on the bottom of the first lifting frame 2. The rotating plate 3 has symmetrical rotating rods on both sides. The rotating rods are inserted into the inside of the first mounting rod 201, so that the rotating plate 3 can rotate inside the first mounting rod 201, thereby changing the tilt angle of the rotating plate 3 and thus changing the tilt angle of the camera 301. The rotating plate 3 can provide a mounting position for the camera 301, so that the camera 301 has a place to be installed. At the same time, the rotating plate 3 can drive the camera 301 to flip up and down by rotating, thereby changing the tilt angle of the camera 301, so that the camera 301 can monitor the cutting head from different tilt angles.

[0032] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The present invention provides an embodiment of a high-precision omnidirectional vision positioning control system based on laser cutting;

[0033] The system includes a second cylinder 4, a second mounting rod 5, a mounting block 6, a lifting rod 7, and a third lifting frame 8. Multiple second cylinders 4 are mounted on the top of the first lifting frame 2. A second lifting frame 401 is mounted on the output end of each second cylinder 4. The second cylinders 4 convert pneumatic energy into kinetic energy, thereby driving the second lifting frame 401 to move up and down. The second lifting frame 401 has a rectangular ring structure and supports the rotating plate 3. The up-and-down movement of the second lifting frame 401 can simultaneously drive four rotating plates 3 to rotate up and down, changing the tilt angle of the rotating plates 3. Multiple second mounting rods 5 are symmetrically mounted on the inner side of the second lifting frame 401. A mounting frame 501 is mounted on one end of each second mounting rod 5, and the top of the mounting frame 501 is movable through it. A transparent plate 502 is installed, and a first threaded rod 503 is installed through the front of the mounting frame 501. A second mounting rod 5 provides an installation position for the mounting frame 501, allowing it to be installed. The mounting frame 501 has a U-shaped structure and serves to install the transparent plate 502. The transparent plate 502 is inserted into the mounting frame 501 from the top and protects the camera 301 by shielding it from dust generated during cutting. This reduces the direct adhesion of dust to the camera 301, preventing unclear images and minimizing damage to the camera 301. The first threaded rod 503 rotates... The first threaded rod 601 can be used to press and fix the transparent plate 502, ensuring its stability and facilitating its installation. Reverse rotation of the first threaded rod 503 can release the fixing of the transparent plate 502, making it easy to remove and replace a damaged transparent plate 502, simplifying the replacement process. A mounting block 6 is installed on the top of the first lifting frame 2, and a second threaded rod 601 is installed through one side of the mounting block 6. The mounting block 6 provides an installation position for the lifting rod 7, allowing it to be installed and providing guidance for its vertical movement. The second threaded rod 601 can press and fix the lifting rod 7 by rotation, ensuring its stability. The top of the mounting block 6... A lifting rod 7 is installed through the mounting block 6, with a handle 701 on one side. The lifting rod 7 passes through the top and bottom of the mounting block 6, providing an installation position for the third lifting frame 8. The lifting rod 7 can move the third lifting frame 8 up and down by moving it. The handle 701 provides a handhold for the operator, allowing them to easily move the lifting rod 7 up and down. The handle 701 also prevents the lifting rod 7 from detaching from the mounting block 6. The third lifting frame 8 is installed at one end of the lifting rod 7, and multiple wiping cloths 801 are symmetrically installed on its outer side. The third lifting frame 8 has a rectangular ring structure, facilitating the symmetrical installation of the wiping cloths 801 around its perimeter.This allows the wiping cloth 801 to wipe the four transparent panels 502. The third lifting frame 8 provides an installation position for the wiping cloth 801, ensuring it has a place to be installed. Simultaneously, the vertical movement of the third lifting frame 8 moves the wiping cloth 801 up and down, enabling it to wipe the transparent panels 502 clean, thus preventing dust from affecting the clarity of the camera 301's image of the cutting head.

[0034] Working Principle: Before using the high-precision omnidirectional vision positioning control system based on laser cutting, it is necessary to check whether there are any problems affecting its use. First, connect the connecting plate 101 to the cutting machine, and simultaneously surround the outside of the cutting head of the cutting machine with the first lifting frame 2 to facilitate the monitoring of the cutting head by the camera 301. The first cylinder 1 can drive the first lifting frame 2 to move up and down, thereby changing the height of the first lifting frame 2, which in turn drives the camera 301 to move up and down. The camera 301 can monitor the cutting head from different heights. At the same time, the second cylinder 4 drives the second lifting frame 401 to move up and down. When the second lifting frame 401 moves up and down, it can cause the rotating plate 3 to rotate up and down, thereby changing the tilt angle of the camera 301 on the rotating plate 3. This allows the camera 301 to observe the cutting machine's cutting from different tilt angles at different heights. The camera 301 is monitored by a transparent plate 502, which protects the camera 301 from dust generated during cutting, preventing it from falling directly onto the camera and affecting its shooting effect. The transparent plate 502 can be released by rotating the first threaded rod 503 in the opposite direction, facilitating the removal and replacement of any damaged plates. When dust covers the transparent plate 502 and affects the camera's shooting effect, the third lifting frame 8 can be moved up and down by holding the handle 701 and moving the lifting rod 7. This movement of the third lifting frame 8 allows the wiping cloth 801 to wipe the surface of the transparent plate 502, removing the dust and ensuring the camera 301's clear monitoring of the cutting head.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
