Description

Technical Field

[0001] The invention belongs to the technical field of automatic welding control, and in particular relates to a robot double T-nail automatic control welding system. Background Art

[0002] In the manufacturing workshop of automobile factories, the stability and reliability of various equipment on the automatic production line play an important role in ensuring the efficient production of the production line. In order to adapt to and improve the competitiveness of automobile brand production, the production capacity of each automatic line is usually set to high flexibility, high beat and high output for production. However, as one of the key and important equipment in the automatic line, the T-nail welding control system, whether it runs stably and reliably will directly affect the beat of the line and the quality of the product.

[0003] At present, T-nail welding equipment may produce various faults during long-term operation. The common welding equipment fault handling and troubleshooting solutions are: first, check and analyze according to the state and phenomenon of the fault, determine the specific cause of the fault, and finally determine whether to use tools or software for diagnosis and repair. A series of troubleshooting processes will take up extra time on the production line. At the same time, the repair time of the fault depends on the difficulty of the fault and the ability level of the engineer to determine the length of the power outage of the line. In addition, when it is difficult to judge the state of the equipment fault and the maintenance cannot be completed in a short time, power outages often cause serious economic losses. This traditional model can only rely on the completion of the current fault before continuing production operations. The production rhythm of each line in the workshop upstream and downstream will be stagnant, reducing the production efficiency of the line, and ultimately affecting the production indicators of the workshop.

[0004] The existing T-nail welding control system uses two welding systems to work. When one welding system fails, the other welding system is enabled to continue working to ensure the normal operation of the welding work. However, switching between the two welding systems is relatively troublesome. For this reason, the present invention proposes a robot double T-nail automatic control welding system.

[0023] The present invention has the following beneficial effects:

[0024] The present invention sets a replacement component, sets a belt driven by a motor inside the installation frame, and a circle of external racks is sleeved on the outside of the belt. The belt is driven by the motor to rotate, and the rotation direction of the belt controls the rotation direction of the transmission rod. When a group of welding guns fails, it is necessary to move the group of welding guns to one side, and move the other group of welding guns to the center position to replace the failed welding guns to continue working. Therefore, the belt controls the rotation direction to control the movement direction trajectory of the two groups of welding guns. The rotation of the belt drives the driving wheel, the first bevel gear, the second bevel gear and the screw rod inside to rotate. During the rotation of the screw rod, the movable bearing is driven to move on its surface, thereby driving the installation block to move. Since a group of connecting components are set on both sides of the installation block, and the connecting components are connected through a quick release component It is connected to the welding gun, and thus, ultimately controls the moving direction of the welding gun; on the other hand, when the belt rotates, it drives the transmission gear, the passive gear and the transmission rod meshing with it through the external rack to rotate. Since a convex strip is provided on the transmission rod, and a wedge-shaped groove is provided on the L-plate and the connecting block, when the transmission rod rotates, the convex strip will be stuck in the wedge-shaped groove, driving the L-plate or the connecting block to move and bend, and the bending angle is 90°, which ultimately makes the faulty welding gun and the normal welding gun distributed at a 90° angle and away from the robot working arm; this structure can separate the faulty welding gun from the normal welding gun, so that the normal welding gun is not disturbed by the faulty welding gun when working, and it is convenient for the staff to disassemble and repair the faulty welding gun; since a magnetic patch is provided on the outer wall of the mounting frame, when the L-plate is bent, it will be attracted by the magnetic patch.

[0025] The present invention sets a connection component, sets a plurality of connection blocks to be connected, and sets telescopic parts and elastic parts inside the connection blocks, so that the connection blocks can work normally when bent. This structure is simple and effective, and ensures the replacement speed of the welding gun. The elastic parts only ensure bending and have no telescopic characteristics.

[0026] The present invention sets a quick-release component. When the L-plate is bent, the angle between the part of the L-plate connected to the connecting block gradually increases. Therefore, the piston inside the L-plate is pulled outward by the connecting block. When the piston moves outward, the air inside the L-plate is in a sealed state, so the conical head moves inward, and the chuck passes the movable block and is placed on the right side of the movable block. When the L-plate is completely bent and the connecting block on one side of it is also completely bent, the L-plate and the connecting block are in the same straight line. Therefore, the piston moves toward the internal cavity of the L-plate again, and the air inside the L-plate pushes the conical head to move outward. Since the movable block is a double-sided cone, the chuck moves to the left side of the conical head. In this way, the quick release of the welding gun can be completed. The staff can directly remove the welding gun and the connected mounting seat. This operation method is fast and effective. BRIEF DESCRIPTION OF THE DRAWINGS
