[0025] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1-Figure 9As shown, the present embodiment provides an LED display cutting device and process, including an operating base 1 and a U-shaped mounting frame 2, the U-shaped mounting frame 2 is fixedly mounted on the top of the operating base 1, a rotary adjustment motor 3 is fixedly mounted on the inner wall of the top side of the U-shaped mounting frame 2, a transverse mounting bar 4 is fixedly connected to the output shaft of the rotary adjustment motor 3, a limited position slide groove is arranged at the bottom of the transverse mounting bar 4, a transverse driving assembly 5 is installed in the limited position slide groove, a laser cutting head 6 is installed on the transverse driving assembly 5, so as to control the movement of the laser cutting head 6, and at the same time control the rotary adjustment motor 3 to rotate and adjust the transverse driving assembly 5, so as to enable the laser cutting head 6 to achieve transverse and longitudinal cutting, and the laser cutting head 6 is fixedly connected to the transverse driving assembly 5 through a latch connection assembly 7, so as to facilitate the disassembly, assembly and replacement of the laser cutting head 6, and maintenance is relatively convenient, a vertical extension plate 8 is fixedly mounted on the transverse mounting bar 4, and the vertical extension plate 8 is located at On both sides of the laser cutting head 6, lateral mounting blocks 9 are fixedly installed on both sides of the operating base 1, and a vertical telescopic rod 10 is fixed at one end of the lateral mounting block 9. The telescopic end of the vertical telescopic rod 10 is fixedly connected with a positioning bar 11, and a limited mounting groove is provided on the inner wall of the positioning bar 11. An adjustable clamping and positioning component 12 is installed in the limited mounting groove. The adjustable clamping and positioning component 12 is used to clamp and position the LED display screen, and control the extension and retraction of the vertical telescopic rod 10 so that the positioning bar 11 and the adjustable clamping and positioning component 12 drive the LED display screen to move upward, so that the top of the LED display screen is fitted with the vertical extension plate 8. Under the action of the vertical extension plate 8, the LED display screen is kept horizontal to avoid tilted cutting, thereby effectively improving the accuracy of cutting. When in use, the adjustable clamping and positioning component 12 is used to accurately clamp and position the display screen according to the size of the display screen to ensure stability before cutting. Subsequently, by controlling the telescopic action of the vertical telescopic rod 10, the LED display screen is smoothly lifted to a position that fits closely with the vertical extension plate 8. This process automatically corrects the horizontal state of the display screen and effectively prevents cutting errors caused by tilting. During the cutting process, the operator only needs to control the coordinated work of the rotary adjustment motor 3 and the transverse drive assembly 5 to drive the laser cutting head 6 to move flexibly in the horizontal and vertical directions to achieve precise cutting of the LED display screen. The design of the latch connection assembly 7 makes the replacement and maintenance of the laser cutting head 6 quick and easy, adapting to different cutting requirements or maintenance work needs, not only greatly improving the cutting efficiency and accuracy, but also reducing manual intervention through intelligent operation, ensuring the consistency and high quality of the cutting operation.

[0026] The traverse drive assembly 5 includes a drive motor 501 and a drive threaded rod 502. The drive motor 501 is fixed on the inner wall of one end of the limiting slide. The drive threaded rod 502 is rotatably mounted on the inner wall of the other end of the limiting slide through a rotating joint 503. One end of the drive threaded rod 502 is fixedly connected to the output shaft of the drive motor 501. A threaded slider 504 is mounted on the drive threaded rod 502. The threaded slider 504 is slidably engaged in the limiting slide. The laser cutting head 6 is fixed to the threaded slider 504 through a latch connection assembly 7. The drive motor 501 is started, and its output shaft drives the drive threaded rod 502 fixedly connected thereto to rotate. Since the drive threaded rod 502 is mounted on the other end of the limiting slide through a rotating joint 503, it can rotate smoothly in a fixed position. As the drive threaded rod 502 rotates, the threaded slider 504 slides along the limiting slide due to its threaded fit with the threaded rod. This sliding is smooth and precise, ensuring that the laser cutting head 6 can move along a predetermined path. The laser cutting head 6 is firmly fixed to the threaded slider 504 through the latch connection assembly 7. Therefore, as the threaded slider 504 moves, the laser cutting head 6 also moves accordingly, achieving precise cutting of the workpiece.

[0027] The plug-in connection assembly 7 includes a square connection frame 701 and a plug-in block 702. The square connection frame 701 is fixed on the threaded slider 504, the plug-in block 702 is fixed on one end of the laser cutting head 6, and the plug-in block 702 is plugged into the square connection frame 701. A U-shaped mounting frame 2 is fixedly installed on the side wall of the square connection frame 701, and a connecting pin 704 is slidably installed on the U-shaped mounting frame 2. One end of the connecting pin 704 is plugged into the corresponding connecting pin holes on the square connection frame 701 and the plug-in block 702. A lifting handle 705 is fixedly installed on the other end of the connecting pin 704. An annular pad 706 is fixedly sleeved on the connecting pin 704. The annular pad 706 is elastically connected to the U-shaped mounting block 703 through a connecting spring 707. The plug-in block 702 is aligned with the socket of the square connection frame 701 and inserted to ensure that the two are initially aligned. Then, the connecting pin 704 is pushed to slide on the U-shaped mounting block 703 by pulling the handle 705 until one end of the connecting pin 704 is accurately inserted into the corresponding connecting pin hole on the square connecting frame 701 and the plug-in block 702. At this time, the annular pad 706, under the action of the connecting spring 707, provides stable support and pre-tightening force for the connecting pin 704, ensuring that there is no looseness between the plug-in block 702 and the square connecting frame 701. The operation is simple and fast, and the connection is firm and can withstand various forces and vibrations generated during the laser cutting process, ensuring the stable operation of the laser cutting head 6, and facilitating the replacement and maintenance of the laser cutting head 6.

[0028] The adjustable clamping and positioning assembly 12 includes a servo motor 1201 and a bidirectional lead screw 1202. The servo motor 1201 is fixed on the inner wall of one end of the limit mounting groove. The bidirectional lead screw 1202 is rotatably mounted on the inner wall of the other end of the limit mounting groove through a rotating connecting seat 1203. One end of the bidirectional lead screw 1202 is fixedly connected to the output shaft of the servo motor 1201. A connecting slider 1204 is threadedly mounted on the bidirectional lead screw 1202. The connecting slider 1204 is slidably engaged with the limit mounting groove. The connecting sliders 1204 are respectively located at the reverse screw ends of the bidirectional lead screw 1202, and the first U-shaped clamping seat 1205 and the second U-shaped clamping seat 1206 are respectively fixedly installed on the two connecting sliders 1204. The first U-shaped clamping seat 1205 and the second U-shaped clamping seat 1206 are both provided with U-shaped lifting seats 1207 which are symmetrical up and down. The upper and lower U-shaped lifting seats 1207 are connected by a limit slide bar 1208. The first U-shaped clamping seat 1205 and the second U-shaped clamping seat 1206 are slidably installed at the upper and lower ends, and the inner walls of the upper and lower U-shaped lifting seats 1207 are rotatably installed with clamping rollers 1209. The upper and lower symmetrical clamping rollers 1209 are used to position the LED display screen. The first U-shaped clamping seat 1205 and the second U-shaped clamping seat 1206 are threadedly installed with threaded push rods 1210. One end of the threaded push rod 1210 is rotatably connected to the U-shaped lifting seat 1207 through a rotating plate 1211, and the other end of the threaded push rod 1210 is fixedly installed with a screwing head 1212. The servo motor 1201 is started to drive the bidirectional lead screw 1202 to rotate, so that the two connecting sliders 1204 move toward the middle or both sides along the limiting installation groove, thereby driving the first U-shaped clamping seat 1205 and the second U-shaped clamping seat 1206 to adjust the spacing to adapt to LED display screens of different sizes, and conveniently adjust the clamping position of the LED display screen, which is convenient for cutting corners. Next, by screwing the screw head 1212 on the threaded push rod 1210, the threaded push rod 1210 pushes or pulls the U-shaped lifting seat 1207 to move up and down along the limiting slide bar 1208, and adjusts the distance between the upper and lower clamping rollers 1209 to adapt to the thickness of the LED display screen. The design of the clamping rollers 1209 reduces friction and damage during the clamping process and protects the surface of the LED display screen.

[0029] When in use, the operator needs to place the LED display screen to be cut between two clamping rollers 1209 that are symmetrically arranged in the upper and lower parts. The two clamping rollers 1209 are not only made of high-quality materials to ensure their durability and protection of the display screen surface, but also ensure the parallelism between the clamping rollers 1209 and the uniform clamping force on the display screen through precise design. When the display screen is securely placed on the clamping rollers 1209, the operator controls the screwing head 1212 so that the threaded push rod 1210 is smoothly and accurately pushed forward under the guidance of the first U-shaped clamping seat 1205 and the second U-shaped clamping seat 1206. This advancement process ensures that the two clamping rollers 1209 can fit closely to the upper and lower surfaces of the LED display screen, achieve stable positioning of it, and provide reliable support for subsequent cutting work. Next, through the vertical telescopic rod 10, its telescopic action is precisely controlled, and the positioning bar 11 is smoothly pushed upward, thereby driving the LED display screen to move upward as a whole. During this process, the operator needs to pay close attention to the contact between the top of the display screen and the bottom of the vertical extension plate 8 to ensure that the two can fit closely. The design of the vertical extension plate 8 not only enhances the stability of the device, but also ensures the horizontal state of the LED display screen during the cutting process through its flat surface, thereby effectively avoiding cutting errors caused by tilting. The latch connection component 7 shows extremely high convenience and flexibility when installing and fixing the laser cutting head 6. Through a simple latch operation, the laser cutting head 6 can be quickly and firmly fixed on the transverse drive component 5, preparing for subsequent cutting work. Subsequently, the operator controls the precise movement of the transverse drive component 5 so that the laser cutting head 6 can move on the LED display screen according to the preset cutting path. At the same time, the addition of the rotary adjustment motor 3 adds flexibility to the cutting work. By controlling its rotation, the transverse drive component 5 can drive the laser cutting head 6 to switch freely in the horizontal and vertical directions, thereby realizing all-round cutting of the LED display screen. When cutting the corners of the LED display screen, the operator can easily adjust the clamping position by controlling the smooth rolling of the clamping roller 1209 on the LED display screen through the adjustable clamping positioning component 12. This not only makes the corner cutting more convenient and quick, but also greatly improves the flexibility of the operation. It also solves the problem that the LED display screen needs to change the fixed position frequently in the traditional cutting method, thereby greatly improving the cutting efficiency and operation quality.
