Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam cutting equipment technology, and in particular to an automatic focusing device for a high-efficiency foam cutting machine. Background Technology
[0002] After processing, plastic foam needs to be cut into different sizes to meet the specific needs of different application scenarios. A foam cutting machine can be used to cut plastic foam into the required size.
[0003] Existing foam cutting machines require constant adjustment of the foam during cutting to ensure cutting quality. Each adjustment causes the foam surface to come into contact with the worktable, clamps, or other tools, which can easily result in scratches, indentations, or other forms of surface damage. These defects can affect the appearance quality of the final product.
[0004] Therefore, to address the issue that the aforementioned foam cutting machine requires constant adjustment of the plastic foam during cutting, which easily leads to scratches and indentations, an efficient automatic focusing device for the foam cutting machine can be designed. Through the configuration of moving components one, two, and three, a laser radar, a motor, a lead screw, a laser rangefinder, a scanning module, and a controller, the device can flexibly adapt to the placement of the plastic foam, avoiding frequent adjustments to the foam itself. By intelligently adjusting the device to match the actual placement of the foam, the device automatically optimizes the cutting path and focusing position, thereby avoiding frequent adjustments to the foam material and solving the aforementioned problems. Utility Model Content

A controller is installed on the upper end of the right fixing plate. A motor is installed on the right side surface of the front connecting block. A lead screw is fixedly connected to the output end of the motor. A moving block is threaded onto the surface of the lead screw. The inner side of the rear connecting block... A sliding rod is fixedly connected, and a slider is slidably connected to the surface of the sliding rod. A fixed plate two is fixedly connected between the moving block and the slider.

A laser radar is installed on the surface of each of the two mounting blocks on the side away from each other.
[0007] Preferably, the entire working area is first scanned by a lidar to record the specific location, shape, and size of the foam material. When plastic foam is detected, a signal is sent to the controller. The controller then moves the device's moving mechanism to directly above the plastic foam.

[0023] Please see Figures 1-3In this embodiment, the moving component includes an electric slide rail 15, a sliding block 16, and a mounting plate 17. An electric slide rail 15 is mounted on each of the four support columns 1 on their adjacent surfaces. Activating the electric slide rail 15 moves the sliding block 16 along the direction of the electric slide rail 15. The sliding block 16 is slidably connected to the surface of the electric slide rail 15. A mounting plate 17 is installed between two sliding blocks 16. The movement of the sliding block 16 moves the mounting plate 17, and the mechanism connected to the mounting plate 17 also moves accordingly. The moving component 2 includes an electric slide rail 2 18, a sliding block 2 19, and a mounting plate 20. An electric slide rail 2 18 is mounted on the upper surface of each of the two mounting plates 17. A sliding block 2 19 is slidably connected to the upper surface of the electric slide rail 2 18. The mounting plate 20 is fixedly connected to the upper surface of the two sliding blocks 2 19. When the electric slide rail 2 18 is activated, the sliding block 2 19 can move left and right along the electric slide rail 2 18, thereby moving the mounting plate 20. The mechanism connected to the mounting plate 20 will also move left and right.

[0025] During operation, the LiDAR 6 first performs a comprehensive scan of the entire working area, recording the specific location, shape, and size of the foam material. When plastic foam is detected, a signal is sent to the controller 27. The controller 27 controls the moving mechanism to move the device directly above the plastic foam. The scanning module 14 uses visual recognition technology to acquire the shape and size information of the foam material. The laser rangefinder 10 measures the distance between the cutting head and the working surface. The controller 27 calculates the optimal cutting path and focus position according to a preset algorithm, and then issues commands to control the moving components one, two, and three to perform actions. During the cutting process, the laser rangefinder 10 continuously detects the distance between the cutting head and the material surface. Any changes are immediately fed back to the controller 27, which quickly makes corresponding adjustments to ensure that the cutting head of the laser cutting machine 24 always maintains the optimal working distance. The LiDAR 6 continuously monitors the surrounding environment. If any abnormal situation is detected, such as personnel approaching, the machine will stop operating in time to ensure operational safety. This device can flexibly adapt to the placement position of the plastic foam, avoiding frequent adjustments to the foam itself. Through intelligent adjustment, the device matches the actual placement position of the foam and automatically optimizes the cutting path and focus position. This ensures precise cutting every time, avoiding frequent adjustments to the foam material. Activating the electric slide rail 15 moves the sliding block 16 along the electric slide rail 15. This movement of the sliding block 16 moves the mounting plate 17, causing the mechanism connected to the mounting plate 17 to move as well, thus moving the upper part up and down. Activating the electric slide rail 2 18 moves the sliding block 19 left and right along the electric slide rail 2 18, thus moving the mounting plate 2 20. The mechanism connected to the mounting plate 2 20 also moves... The laser cutting machine 24 can move left and right by moving the electric slide rail 21 via the mounting plate 20. This causes the mechanism connected to the electric slide rail 21 to move, thereby moving the laser cutting machine 24. Activating the electric slide rail 21 can also move the sliding block 22, which in turn moves the mounting table 23 forward and backward. The mechanism connected to the mounting table 23 will also move, thereby moving the laser cutting machine 24 forward and backward, enabling the laser cutting machine 24 to move in all directions. The drive wheel 26 is equipped with a power source and can actively drive the equipment to the designated position to achieve automated positioning.
[0026] Through the above steps, the LiDAR 6 first performs a comprehensive scan of the entire working area, recording the specific location, shape, and size of the foam material. When plastic foam is detected, a signal is sent to the controller 27. The controller 27 controls the moving mechanism to move the device directly above the plastic foam. The scanning module 14 uses visual recognition technology to obtain the shape and size information of the foam material. The laser rangefinder 10 measures the distance between the cutting head and the working surface. The controller 27 calculates the optimal cutting path and focus position according to a preset algorithm, and then issues commands to control the moving components one, two, and three to perform actions. During the cutting process, the laser rangefinder 10 continuously detects the distance between the cutting head and the material surface, and any changes are recorded. All data will be immediately fed back to the controller 27, which will quickly make corresponding adjustments to ensure that the cutting head of the laser cutting machine 24 is always kept at the optimal working distance. The laser radar 6 continuously monitors the surrounding environment. Once an abnormality is detected, such as personnel approaching, the machine will stop operating in time to ensure operational safety. This device can flexibly adapt to the placement of plastic foam, avoiding frequent adjustments to the foam itself. Through intelligent adjustment, it matches the actual placement of the foam and automatically optimizes the cutting path and focus position to ensure that each cut is accurate. This avoids frequent adjustments to the foam material, solving the problem that common foam cutting machines need to constantly adjust the plastic foam when cutting plastic foam, which easily leads to scratches and indentations.
