Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In this embodiment, refer to Figure 1 - Figure 6 The screen cutting device specifically implemented includes a base 1, a support 2, and a sliding plate 3 slidably mounted on the base 1. The support 2 is fixedly mounted on the upper end of the base 1. The base 1 is provided with a first driving assembly 11 that cooperates with the sliding plate 3. The sliding plate 3 is provided with a rotatable suction cup 4, and the lower end of the sliding plate 3 is provided with a rotating component 31 that cooperates with the suction cup 4. The support 2 is mounted with a second driving assembly 21. The output end of the second driving assembly 21 is provided with a fixed seat 5. The middle part of the fixed seat 5 is provided with a fixed plate 51, and the two ends of the fixed seat 5 are provided with slidable connecting plates 52. The fixed seat 5 is provided with a third driving assembly 53 that cooperates with the connecting plates 52. Both the fixed plate 51 and the connecting plate 52 are provided with cutting components 6 that can slide up and down. The suction cup 4 is rotatably mounted on the sliding plate 3 through bearings and rotates on the sliding plate with the drive of the rotating component 31, thereby adjusting the angle of the screen so that the screen can cooperate with the cutting components 6 at different angles, thereby cutting screen edges of different shapes.

[0023] In use, the screen is placed on the suction cup 4 to secure it firmly. Then, through the coordinated action of the first drive component 11, the rotating component 31, and the second drive component 21, the screen moves along a preset path, cooperating with the cutting components 6 on the fixed plate 51 and the connecting plate 52 to simultaneously and precisely cut multiple screens. Driven by the third drive component 53, the connecting plate 52 slides, adjusting the distance between the cutting components 6 to cut screens of different sizes. The entire cutting process is automated, improving cutting efficiency, ensuring cutting accuracy, reducing manual intervention, and achieving efficient and precise screen processing to meet diverse production needs.

[0024] The cutting assembly 6 includes a cutting head 61 and an output component 62. The output component 62 is fixedly installed at one end of the fixing plate 51 and the connecting plate 52, and the cutting head 61 is located at the output end of the output component 62. The cutting head 61 includes a connecting sleeve 611 and a cutting head 612. The cutting head 612 is detachably installed at one end of the connecting sleeve 611 via a fixing sleeve 613. The other end of the connecting sleeve 611 is provided with a fixing pin 614 that cooperates with the output end of the output component 62. The output component 62 can be driven by a cylinder, hydraulic cylinder, or servo motor. In this embodiment, a cylinder is used as the output component 62. The connecting sleeve 611 is connected to the end of the cylinder rod via the fixing pin 614, and the fixing sleeve 613 is connected to the connecting sleeve 611 via a threaded connection, thereby firmly fixing the cutting head 612. When the cylinder is driven, the cylinder rod drives the cutting head 612 to move up and down through the connecting sleeve 611, thereby contacting the screen and completing the cutting action. When the cutting head 612 is worn or needs to be replaced, the cutting head 612 can be easily removed and replaced simply by turning the retaining sleeve 613, ensuring cutting quality and efficiency.

[0025] The third drive assembly 53 includes a bidirectional lead screw 531, a drive motor 532, and two lead screw nuts 533. The bidirectional lead screw 531 is rotatably mounted on the fixed base 5 via bearings. The two lead screw nuts 533 are symmetrically arranged at both ends of the bidirectional lead screw 531. The drive motor 532 is located at one end of the fixed base 5 and is connected and cooperates with the bidirectional lead screw 531. The connecting plate 52 is provided with a nut seat 521 that cooperates with the lead screw nuts 533. In use, the drive motor 532 drives the bidirectional lead screw 531 to rotate, and through the cooperation of the lead screw nuts 533 and the nut seats 521, it drives the connecting plates 52 at both ends to move in opposite directions, thereby precisely adjusting the spacing of the cutting assembly 6 and ensuring the accuracy of the cutting dimensions.

[0026] Both sides of the fixed base 5 are provided with linear guides 54, and both sides of the connecting plate 52 are provided with sliding blocks 522 that slide in cooperation with the linear guides 54. Through the cooperation of the linear guides 54 and the sliding blocks 522, the connecting plate 52 slides smoothly along the linear guides 54, thereby ensuring the stability and accuracy of the cutting process. This avoids cutting errors caused by the shaking of the connecting plate 52, thus improving the overall cutting quality and reducing the scrap rate.

[0027] A guide ring 7 is fixedly installed on the sliding plate 3. The lower end of the suction cup 4 has a guide groove 41 that mates with the guide ring 7. One end of the guide ring 7 has a connector 71 for external connection. The upper end of the guide ring is inserted into the guide groove and connected to the inside of the suction cup 4 through the guide groove 41. This ensures that the suction cup 4 maintains stable suction force during rotation, firmly adhering to the screen and preventing the suction force from decreasing or disappearing due to compression of the air tube during rotation, which could cause the screen to shift during cutting. This ensures cutting accuracy and safety. Simultaneously, the guide ring 7 also provides support and guidance. The precise fit between the guide ring and the guide groove keeps the suction cup 4 stable during rotation, avoiding cutting deviations caused by vibration. A sealing ring that mates with the guide ring is provided in the guide groove, effectively preventing gas leakage and ensuring the suction effect of the suction cup 4.

[0028] During use, it connects to external equipment such as a compressor via connector 71 to adjust the air pressure inside the suction cup 4, ensuring sufficient suction force and preventing the screen from shifting during cutting. The air pressure can be flexibly adjusted according to different screen materials and thicknesses to meet various cutting needs, further improving cutting efficiency and precision.

[0029] Both the first drive assembly 11 and the second drive assembly 21 are either lead screw and slider modules or linear motor modules. Both lead screw and slider modules and linear motor modules can achieve high-precision linear motion, ensuring the accurate movement trajectory of the cutting head 612. Lead screw and slider modules and linear motor modules are suitable for different application requirements. Lead screw and slider modules are suitable for cutting scenarios with high load and high precision requirements, while linear motor modules are suitable for high-speed and high-response cutting tasks. In this embodiment, the first drive assembly 11 uses a lead screw and slider module, which can drive the suction cup 4 for high-precision positioning, ensuring the stability and accuracy of the cutting process. The second drive assembly 21 uses a linear motor module, which drives the cutting assembly 6 to move quickly, working in conjunction with the first drive assembly 11 to achieve efficient cutting. During use, the drive assembly can be flexibly selected according to different cutting requirements, thereby optimizing cutting efficiency and accuracy, improving equipment adaptability and flexibility, meeting diverse production needs, and ensuring stable and reliable cutting quality.

[0030] The beneficial effects of this utility model are as follows: Through the coordinated action of the first driving component 11, the second driving component 21, and the rotating component 31, the sliding plate 3, the suction cup 4, and the cutting component 6 work together to achieve synchronous cutting of multiple screens, thereby improving cutting efficiency. Furthermore, through the cooperation of the third driving component 53 and the connecting plate 52, the spacing between the cutting components 6 is adjusted to adapt to the cutting requirements of screens of different sizes, ensuring cutting accuracy and stability.
