Description

Technical Field

[0001] This invention relates to the field of arc welding equipment technology, specifically to an automated welding equipment for box assembly. Background Technology

[0002] In industrial production, enclosure-type components are widely used in many fields such as machinery, electronics, and automobiles. The welding quality of the enclosure directly affects its sealing performance, strength, and overall performance, which in turn affects the operational stability and service life of related equipment. The welding of the enclosure assembly generally involves first welding the internal frame, then welding the side panels to the various surfaces of the frame, and finally leaving space for the enclosure door for final installation.

[0003] Existing automated welding equipment for box assemblies requires a conveyor structure to transport the frame and complete the welding operation at a designated position. However, during the transport process, the bottom surface of the frame is in close contact with the conveyor belt, making it difficult to weld the bottom side panels. At this point, the frame needs to be flipped. Existing welding flipping equipment requires lifting and flipping the box frame, which increases the driving force required for flipping and is also prone to excessive compression of the frame during clamping and flipping, resulting in wear or even dents on the frame surface. Summary of the Invention

[0004] The purpose of this invention is to provide an automated welding equipment for housing assembly that can improve the turning efficiency while reducing damage to the housing during the turning process, so as to solve the problems mentioned in the background art.

[0033] The output mechanism also includes a rotating column 27 fixedly installed at the bottom of the rotating table 5. Mounting brackets 28 are fixedly connected to both sides of the machine body 1. The mounting brackets 28 are provided with inclined sliding grooves 29. The two ends of the third drive roller 21 are slidably attached to the inner walls of the inclined sliding grooves 29 on both sides. The machine body 1 is provided with a control component 30 for linking and controlling the position of the second drive roller 18 and the third drive roller 21 when driving the rotating table 5 to rotate. The control component 30 is used to ensure that the first conveyor belt 4 is always in a taut state and does not affect the rotation of the rotating table 5. The side of the machine body 1 is provided with an output component 31 for outputting the box on the second conveyor belt 6.

[0034] The control component 30 includes a drive motor 32 fixedly installed inside the body 1. The drive motor 32 is preferably a YYHS-40. The output end of the drive motor 32 is coaxially fixedly connected to the bottom surface of the rotating column 27. A reciprocating screw 33 is rotatably connected inside the body 1. The reciprocating screw 33 passes through the guide frame 19 and is threadedly connected to the guide frame 19.

[0035] The output component 31 includes a guide rail 36 fixedly installed on the side of the body 1. An output platform 37 is slidably connected to the guide rail 36 in the horizontal direction. The side of the output platform 37 is in contact with the rotating platform 5. A tension spring 38 is fixedly connected to the output platform 37. The end of the tension spring 38 away from the output platform 37 is fixedly connected to the body 1.

[0036] Working principle: The box frame 40 is conveyed to the second conveyor belt 6 by the first conveyor belt 4. At this time, one end of the second conveyor belt 6 is close to the end of the first conveyor belt 4, so as to facilitate the stable conveying of the frame 40 on the first conveyor belt 4 to the second conveyor belt 6. After the frame 40 reaches the middle position on the upper side of the second conveyor belt 6, the second conveyor belt 6 stops running. Then, the arc welding head 3 controlled by the robotic arm 2 can weld the frame 40 and the side plate 22. The side plate 22 can be gripped and installed on the frame 40 by the robotic claw. The arc welding head 3 can weld the side plates 22 on all sides from the inside of the frame 40 through the opening on one side of the box door.

[0037] When welding is required on the bottom surface, the second conveyor belt 6 is controlled to drive and transport the frame 40, while the lifting platform 7 is controlled to move down to the set position, so that the drive shaft 8 is below the second conveyor belt 6. At this time, the second conveyor belt 6 transports the frame 40 onto the third conveyor belt 9, causing the lower edge of the frame 40 near the third conveyor belt 9 to tilt and fall onto the third conveyor belt 9 first. The tilt angle of the third conveyor belt 9 in a stable state is 45°. When the frame 40 falls onto the third conveyor belt 9, the third conveyor belt 9 and the tilting plate 12 will rotate around the drive shaft 8, compressing the damping spring 15 while the rotating shaft 13 slides on the arc frame 11. At this time, due to the frame 40 Under pressure, the angle between the third conveyor belt 9 and the lifting platform 7 will be less than 45°. Then, the lifting platform 7 will be slowly raised by the electric telescopic rod 39, so that the tilting plate 12 and the frame 40 will move upward in a relatively stable state until the drive shaft 8 is higher than the second conveyor belt 6. Then, the drive shaft 8 is controlled to rotate, so that the third conveyor belt 9 pushes the frame 40 in the opposite direction to the second conveyor belt 6. This allows the side that is in contact with the surface of the third conveyor belt 9 to be transported to the position that is in contact with the surface of the second conveyor belt 6. The bottom surface that was originally in contact with the second conveyor belt 6 has now been flipped to the side position, and the equipment can be controlled to run again to complete the welding of the unwelded side.

[0038] It is worth noting that the overall operation of the flipping structure is relatively stable, without the need to clamp the frame 40, and the frame 40 will not be impacted or obstructed during the flipping process, reducing the probability of damage to the frame 40 as a whole. After the flipping is completed, the control lifting platform 7 moves down and resets to the set position, so that the drive shaft 8 is lower than the rotating platform 5. After that, the rotating platform 5 will not be obstructed by the third conveyor belt 9. During the welding process, the drive motor 32 can drive the rotating column 27 and the rotating platform 5 to make the box frame 40 on the second conveyor belt 6 rotate horizontally to adjust its orientation.

[0039] When the rotating column 27 rotates, it drives the bevel gear ring 34 to drive the bevel gear 35 to rotate. The bevel gear 35 drives the reciprocating screw 33, causing the mounting frame 28 and the sliding frame 17 to slide back and forth in the horizontal direction. During each 90° rotation of the rotating table 5, the mounting frame 28 will complete one reciprocating movement along the reciprocating screw 33. When the rotating table 5 rotates 45°, the mounting frame 28 moves to the end of the reciprocating screw 33 away from the bevel gear 35 and begins to slide in the opposite direction. This ensures that when the rotating table 5 is at the corner position pointing towards the first conveyor belt 4, the mounting frame 28 and the sliding frame 17 will drive the second drive roller 18 and the third drive roller 21 to move away from the rotating table 5 synchronously, avoiding continuous wear of the outer wall of the first conveyor belt 4 by the edge of the rotating table 5.

[0040] When the sliding frame 17 moves horizontally, both ends of the third drive roller 21 slide synchronously downwards under the dual guidance of the vertical slide groove 20 and the inclined slide groove 29. This causes the distance between the second drive roller 18, the first drive roller 16 and the third drive roller 21 to increase synchronously when the distance between the first drive roller 16 and the second drive roller 18 decreases, keeping the first conveyor belt 4 taut at all times. When the second drive roller 18 slides horizontally, it drives the second slide bar 26 to slide synchronously to the side of the first slide bar 25. The top surfaces of the second slide bar 26 and the first slide bar 25 are flush, which ensures that the inner wall of the first conveyor belt 4 is always stably supported. At the same time, it does not affect the conveying of objects on the first conveyor belt 4. Only a small section of the first conveyor belt 4 around the second drive roller 18 is adjusted, without affecting the transport of the frame 40 on the first conveyor belt 4 in the area between the first drive roller 16 and the second drive roller 18.

[0041] When the rotating table 5 rotates, the edge of the rotating table 5 will push the output table 37 to slide horizontally along the guide rail 36. After the rotating table 5 has finished rotating, the tension spring 38 pulls the output table 37 to fit against the edge of the rotating table 5 again. When it is necessary to output the box on the second conveyor belt 6, rotate the output end of the second conveyor belt 6 to fit against the output table 37, start the second conveyor belt 6 to output the box above onto the output table 37 to complete the unloading operation.
