Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting of non-standard hinged door panels, and in particular to an automatic cutting device that is compatible with a variety of hinged door panels. Background Art

[0002] With the steady and rapid development of China's economy, infrastructure construction, urban village reconstruction, shantytown renovation, old village renovation, and new rural development are being implemented across the country. A large number of resettlement housing units have sprung up. With the recovery of the real estate industry, a large number of commercial housing units have gradually entered the market. Simultaneously, with the opening of China's borders, the volume of imported and exported goods has increased, resulting in a growing demand for doors. However, as people's living standards continue to improve, the demand for door quality is also becoming increasingly higher. Currently, domestic door manufacturers still largely rely on traditional manufacturing methods, relying on manual labor. This leads to high production costs, low production efficiency, and significant quality impacts from manual labor. The workers' working environment is noisy and dusty, and the open operating environment is prone to safety accidents, which is detrimental to their physical and mental health. Traditional production methods can no longer meet the actual production needs of the market. To survive and thrive, traditional companies must transform and upgrade.

[0003] Large-scale door manufacturers in China have begun to introduce automated production equipment. Due to the wide variety of door specifications and the preponderance of non-standard components, the performance requirements for automated production equipment are also high. While ensuring product quality, compatibility with the equipment must also be considered. Existing laser cutting technology for non-standard hinged door panels uses either 45° or 90° positioning, both of which present certain challenges. When cutting circular or elliptical holes, the robot must maintain the laser perpendicular to the work surface and every point along the laser cutting path to ensure a standard circular or elliptical shape. Using a 45° tilted positioning method makes it difficult to guarantee quality, requiring extensive debugging to achieve the desired cutting effect, reducing production efficiency. Furthermore, the 45° tilted positioning method makes it difficult to achieve X, Y, and Z axis movement within the robot's gripper, preventing the robot from freely moving within the plane of cutting, impacting processing efficiency. Furthermore, using a 90° positioning method forces the laser cutting beam toward the user, posing a safety risk. The above two positioning methods are not convenient for setting up laser cutting protection mechanisms, and there is a possibility that the laser beam of the laser during the cutting process may damage other components, affecting the performance of the equipment.

[0004] Based on the above problems, in order to better solve the problems of existing automated laser cutting production equipment and promote enterprise transformation, upgrading and rapid development, an automated cutting device compatible with multiple hinged door panels is proposed. Summary of the Invention

[0051] When using this device, the product to be processed is transported via the first section of the chain drive assembly 1. When the product to be processed reaches the laser cutting position, the stop cylinder 32 activates, and the stop plate 36 extends, preventing the product from being processed from continuing. Simultaneously, the first section of the chain drive assembly 1 stops operating, indicating that the product to be processed is in place. After the product to be processed is in place, the side push drive motor 43 activates, driving the side push plate 45 to extend until one side of the product to be processed contacts the other side of the chain drive assembly 12. The side push drive motor 43 then reverses, driving the side push plate 45 to retract, completing the lateral positioning of the product to be processed and ensuring consistent suction position. After the product to be processed is laterally positioned, the Z-axis cylinder 547 extends, the electromagnetic suction cup 549 works first, and then the vacuum suction cup 5410 works. When the electromagnetic suction cup 549 and the vacuum suction cup 5410 completely absorb the product to be processed, the Z-axis cylinder 547 retracts and the X-axis cylinder 545 extends at the same time. When the height of the product to be processed is greater than the height of the support frame 552, the drive motor 543 of the clamping mechanism 55 works, driving the support frame 552 to move. When the support frame 552 is in place, the Z-axis cylinder 547 extends again, placing the product to be processed on the support frame 552. The Z-axis cylinder 547 retracts again, and the X-axis cylinder 545 retracts at the same time, indicating that the product to be processed has completed the laser cutting work position. When the product to be processed is placed in the laser cutting work position, the side push drive motor 43 and the drive motor 543 of the clamping mechanism 55 work until the side push plate 45, the return plate 554 and the side of the support frame 552 contact the product to be processed, and the side push drive motor 43 and the drive motor 543 of the clamping mechanism 55 stop working, that is, the product to be processed is completely positioned. When the product to be processed is completely positioned, the robot assembly 6 works according to the cutting requirements. When the laser cutter 63 cuts the side corners of the product to be processed, the drive motor 543 in the second protective assembly 8 drives the side protective plate 82 to move. When the laser cutter 63 cuts the middle area, the cylinder 75 extends, and at the same time, the drive motor 543 in the first protective assembly 7 drives the protective plate 76 to move. The first protective assembly 7 and the second protective assembly 8 can effectively prevent the waste heat generated by the laser cutter 63 from damaging other parts of the device, while improving the safety performance of the device.

[0052] When the product to be processed is cut into a finished product, the first guard assembly 7, the second guard assembly 8, and the side push servo assembly 4 all return to their initial origin positions. At the same time, the X-axis cylinder 545 and the Z-axis cylinder 547 extend, and the electromagnetic suction cup 549 and the vacuum suction cup 5410 operate to absorb the finished product. The clamping mechanism 55 returns to its initial origin position, and the Z-axis cylinder 547 continues to extend, placing the finished product on the chain drive assembly 12. After the finished product is placed in place, the stop plate 36 retracts, and the first chain drive assembly 1 operates. The finished product flows into the second chain drive assembly 2 and proceeds to the next process. The product to be processed completes the laser cutting process.

[0053] The automated cutting device for hinged door panels provided by this embodiment can process hinged door panels with the same cross-section but different lengths, as well as hinged door panels with similar cross-sections but different lengths. Furthermore, it effectively protects the device's other mechanical mechanisms from damage during the laser cutting process, ensuring the device's safety and reliability. Furthermore, it effectively reduces production costs, improves work efficiency, reduces workload, and reduces human resources, demonstrating excellent practicality and promotional value.
