Description

Technical Field

[0001] This invention relates to the field of rail transit, and in particular to a fully automated laser edge-sealing production line and method for multi-model rail transit door panels. Background Technology

[0002] Currently, most rail transit vehicle door panels adopt a "sandwich" structure, which uses adhesive to bond the frame, skin, and honeycomb structure together. Excess adhesive generated during the bonding process needs to be cleaned manually, and then sealant is applied again to ensure that external moisture does not enter the interior of the door.

[0003] However, manual operation makes it difficult to ensure the reliability of door panel quality, and low automation leads to low efficiency. Summary of the Invention

[0004] Purpose of the invention: To address the shortcomings and defects of existing technologies, this invention provides a fully automated laser edge-sealing production line and method for multi-model rail transit door panels. The door panel is sealed around its perimeter through laser welding, preventing excess adhesive from curing and the ingress of external moisture. This method is highly efficient, highly automated, highly safe, and ensures reliable door panel quality.

[0005] Technical solution: The fully automatic laser edge banding production line for multi-model rail transit doors of the present invention is characterized by including an automatic feeding port, an automatic feeding trolley, a seven-axis slide table, a handling robot, a door feeding gripper, a servo positioner, a door positioning component, a lifting component, a door positioning gripper, a laser welding robot, a control cabinet, a part transfer mechanism, a dust removal system, and a ground precision positioning mechanism.

[0006] The automatic feeding port is equipped with an automatic feeding trolley, and the handling robot is equipped with a door-shaped feeding gripper. The handling robot moves along a seven-axis slide.

[0007] The seven-axis slide table is equipped with a door leaf positioning component, a lifting mechanism component, a laser welding robot, and a servo positioner on its side. The lifting mechanism component is equipped with a door leaf positioning gripper. The laser welding robot is controlled by a control cabinet and the servo positioner flips the door leaf.

[0008] The seven-axis slide table is equipped with a workpiece transfer mechanism at its end, and the servo positioner is equipped with a dust removal system on its side.

[0009] The dust removal system is used to treat dust and welding slag during the welding process.

[0010] The servo positioner, door leaf positioning component, elevator component, and door leaf positioning gripper are four in number, forming four sets of laser welding fixtures.

[0011] The fully automated laser edge-sealing production method for multi-model rail transit door panels of the present invention is characterized by using the production line of the present invention.

[0012] In this process, workers push the automatic feeding trolley into the ground precision positioning mechanism. The transport robot, carrying the door panel feeding gripper, goes to the automatic feeding trolley to grab the door panel. After picking up the door panel, the transport robot moves along the seven-axis slide to the welding position and puts the door panel into the door panel positioning component. The lifting component, carrying the door panel positioning gripper, descends and together with the door panel positioning component, achieves precise positioning and clamping of the door panel.

[0013] The control cabinet controls the laser welding robot to start welding the front of the door leaf. After the front welding is completed, the servo positioner rotates to weld the back of the door leaf. After the door leaf welding is completed, the servo positioner returns to the initial position, the lifting assembly raises the door leaf positioning gripper, and the handling robot picks up the door leaf with the door leaf loading gripper. It moves along the seven-axis slide to the placement position and places the door leaf on the lower transfer mechanism. This mechanism then transports the finished product out of the workstation.

[0014] The door panels mentioned above are those used in rail transit vehicles.

[0015] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: This invention achieves improved efficiency and optimized quality through high automation and intelligence, enabling flexible production of door panels of different specifications and sizes. It is mainly applied to automatic laser welding and information management of rail vehicle door panels. It solves the problems of glue overflow, glue removal, and sealing in rail transit adhesive door panels. By welding the door frame and skin into a single unit through laser welding, the cured glue will not overflow, eliminating the need for cleaning excess glue, secondary sealing, and manual glue removal. This ensures the sealing of the door panel, promotes automation, improves production efficiency, and simultaneously considers aesthetics and safety. Attached Figure Description

Detailed Implementation

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] This invention relates to a fully automated laser edge-sealing production line for multi-model rail transit doors, comprising an automatic feeding port 1, an automatic feeding trolley 2, a seven-axis slide table 3, a transport robot 4, a door door feeding gripper 5, a servo positioner 6, a door door positioning assembly 7, a lifting assembly 8, a door door positioning gripper 9, a laser welding robot 10, a control cabinet 11, a part transfer mechanism 12, a dust removal system 13, and a ground precision positioning mechanism 14. The automatic feeding port 1 is equipped with an automatic feeding trolley 2, and the transport robot 4 is equipped with a door door feeding gripper 5, which moves along the seven-axis slide table 3. The seven-axis slide table 3 has the door door positioning assembly 7, the lifting assembly 8, the laser welding robot 10, and the servo positioner 6 on its side. The lifting assembly 8 has the door door positioning gripper 9. The laser welding robot 10 is controlled by the control cabinet 11 and flips the door door using the servo positioner 6. The seven-axis slide table 3 has a part transfer mechanism 12 at its end, and the servo positioner 6 has a dust removal system 13 on its side. Dust and welding slag generated during the welding process are treated by a dust removal system 13. The number of servo positioners 6, door leaf positioning components 7, elevator components 8, and door leaf positioning grippers 9 are four, forming four sets of laser welding fixtures. The door leaf is a rail transit vehicle door leaf.

[0020] The present invention relates to a fully automated laser edge-sealing production method for multi-model rail transit doors. Workers push an automated loading trolley 2 into a ground-based precision positioning mechanism 14. A transport robot 4, carrying a door-mounted gripper 5, moves to the automated loading trolley 2 to pick up the door. After picking up the door, the transport robot 4 moves along a seven-axis slide 3 to the welding position and places the door into a door positioning assembly 7. A lifting assembly 8, carrying a door positioning gripper 9, descends, working together with the door positioning assembly 7 to achieve precise positioning and clamping of the door.

[0021] The control cabinet 11 controls the laser welding robot 10 to start welding the front of the door leaf. After the front welding is completed, the servo positioner 6 rotates to weld the back of the door leaf. After the door leaf welding is completed, the servo positioner 6 returns to the initial position, the lifting assembly 8 raises the door leaf positioning gripper 9, and the handling robot 4 picks up the door leaf with the door leaf loading gripper 5. The robot moves along the seven-axis slide table 3 to the placement position and places the door leaf on the lower part transfer mechanism 12. The mechanism then transports the finished product out of the workstation.

[0022] The entire process is a highly efficient, fully automated cycle. This fully automated laser edge-sealing workstation, through the precise coordination of robots, servo positioners, and positioning fixtures, achieves unmanned operation of the entire process of door panels from loading, positioning, edge-sealing to unloading. This not only significantly improves production efficiency and product consistency, but also ensures high edge-sealing strength, good sealing performance, and a flawless, aesthetically pleasing appearance through laser technology, fully meeting the stringent requirements of the rail transit industry for high quality and reliability.

[0023] This invention targets the rail transit industry, high-end security doors and windows, and the sheet metal industry. It boasts a high degree of automation and good versatility, enabling automatic identification, positioning, and clamping of door panels of different sizes. A laser edge-sealing robot performs welding edge-sealing actions according to a predetermined program. Primarily used for automatic welding of door panels, it can weld various rail transit door panels. The control cabinet controls the handling robot and welding robot, enabling simultaneous production at multiple workstations and improving production efficiency. The multi-directional servo slide system on the handling gripper can grasp door panels of different sizes. The door panel positioning component is suitable for automatic positioning of door panels with different curvatures, angles, and various types; positioning and clamping actions are achieved through PLC control of the surrounding electric cylinders.

[0024] In practice, this laser welding method has been applied to the laser welding of left and right structural door panels in urban rail and intercity vehicles. It meets technical requirements and, through the control system's automatic identification system, quickly and automatically adjusts the fixtures and retrieves the welding program, enabling the production of various high-speed rail door panels in rotation. The laser welding tool system ensures the consistency and reliability of the welded door panels, achieving automated production, reducing occupational health risks, and improving production efficiency. It not only surpasses traditional methods in quality, efficiency, environmental friendliness, and aesthetics, but also perfectly meets the core demands of the rail transit industry for safety, reliability, and long service life.
