Description

Technical Field

[0001] The present invention belongs to the field of advanced manufacturing technology, and particularly relates to an intelligent welding device capable of automatic feeding and its working method. Background Art

[0002] Steel grating is a steel product made by arranging flat steel at a certain interval and cross bars (twisted, square steel, round steel, flat steel, etc.) in a cross arrangement and welding them into a square grid in the middle. Steel grating is mainly used as a water channel cover plate, a steel structure platform plate, a tread plate of a steel ladder, etc. In the existing processing of steel grating, generally, the flat steel is conveyed to the welding station through a conveying mechanism, and the cross bars generally need to be manually placed at specific positions on the flat steel, which requires a large amount of manpower and material resources. At the same time, due to the certain uncontrollability of people, the placement position of the cross bars is not accurate enough, which affects the production quality and production efficiency. At the same time, during the processing of steel grating, the connection between the cross bar and the flat steel needs to be welded. Many existing welding devices are laser welding or gas welding. No matter which kind of welding, during the welding process, the welding head searches for the points to be welded back and forth, and then performs welding. During the process of searching for the welding points, the welding head needs to run back and forth on the track, and also needs to run back and forth on the track during the welding process to weld each point. This not only easily causes missed welding, but also wastes time and resources during the back-and-forth running process. Therefore, the existing welding devices need to be improved.

[0058] Embodiment 3

[0059] In this embodiment, the structure of the welding device is the same as that of the welding device in Embodiment 1 or Embodiment 2. The working method of an intelligent welding device capable of automatic feeding in this embodiment is as follows: 1): First, the clamping component 32 in the feeding and clamping mechanism 3 clamps the flat steel. 2): Then, the lifting drive mechanism 24 in the feeding and clamping mechanism 3 drives the lifting rod 23 to descend and press the flat steel. Then, driven by the drive motor 331, the first driven wheel 335 rotates. Driven by the second belt 302, the third driven wheel 338 rotates together with the first driven wheel 335, so that the second transmission shaft 333 drives the feeding and clamping mechanism 3 to move forward along the second belt 302. At the same time, the third sliding seat 113 on the feeding and clamping mechanism 3 moves forward along the guide rail 102 on the conveying frame 101 to convey the flat steel to the welding mechanism 6. 3): When the flat steel enters the material distributing device 632 in the welding mechanism 6 and is placed on the material distributing combs 6323, the lifting drive mechanism 24 in the feeding and clamping mechanism 3 drives the lifting rod 23 to rise and release the flat steel. 4): At the same time, the feeding mechanism 55 in the cross-bar feeding mechanism 5 feeds the welding mechanism 6, that is, the first drive motor 555 drives the second drive wheel 558 to rotate. Driven by the second drive wheel 558, the driven wheel 556 rotates together with it. The driven wheel 556 drives the drive rod 551 to rotate. Driven by the drive rod 551, the active guide plate 5221 and the driven guide plate 5222 drive the cross-bar to move upward until the cross-bar is driven onto the guide plate 553. Both ends of the cross-bar will enter the material channel 557 between the second limiting plate 554 and the side guide plate 5532, and then run along the material channel 557 to the receiving clamp 5622 in the feeding mechanism 56. Then, the feeding drive mechanism 563 in the feeding mechanism 56 drives the feeding plate 5621 to move towards the welding mechanism 6.

[0060] 5): During the feeding process of the feeding mechanism 56, the material receiving device 66 will move forward to cooperate with the feeding mechanism 56. When the receiving plate 663 moves to a suitable position, the first lifting drive mechanism 634 drives the welding support base 631 to move upward, that is, the sliders at both ends of the welding support base 631 move along the slide rails 611 inside the columns 61. At the same time, the rack 6311 on the welding support base 631 and the transmission gear 6343 on the transmission shaft 6342 move relative to each other. When the cross bar of the receiving plate 663 catches the cross bar, the first lifting drive mechanism 634 drives the welding support base 631 to move downward, and the movement mode of the welding support base 631 is opposite to that when it rises, until the receiving plate 663 drives the cross bar onto the flat steel; 6): Then, the driving cylinder 6621 in the material receiving power mechanism 662 drives the fourth sliding seat 6622 to move back and forth along the first and third guide rails 6612. Driven by the fourth sliding seat 6622, the receiving plate 663 also moves back and forth with it, so as to place the cross bar at a suitable position on the flat steel; 7): The welding host 62 in the welding mechanism 6 can weld the intersection of the flat steel and the cross bar. During the welding process, one or more welding hosts can be selected for welding according to needs; 8): During the welding process, the welded products move forward continuously. When they move to the discharging mechanism 7, the lifting drive mechanism 24 in the discharging mechanism 7 drives the lifting rod 23 to descend to press the products, and then sends them out, that is, the drive motor 71 drives the second drive wheel 73 to rotate. The first transmission wheel 74 on the discharging drive shaft 72 is driven to rotate by the second drive wheel 73, so as to drive the discharging drive shaft 72 to rotate with it. Driven by the discharging drive shaft 72, the second transmission wheels 75 at both ends of the discharging drive shaft 72 located outside the side support frame 105 also rotate together. Since the second transmission wheel 75 is connected to the third transmission wheel 76 through the fifth belt 78, during the rotation of the second transmission wheel 75, the third transmission wheel 76 and the second belt 78 also rotate with it. During the transmission of the fifth belt 78, the first clamping block 304 drives the clamping support 31 in the discharging mechanism 7 to rotate along the belt. At the same time, the sliding seats on both sides of the clamping support 31 move along the guide rails 102 on the discharging support 104 together. During the above working process, each welding host at the welding station can work independently according to needs.

[0061] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements can be made, and these improvements should also be regarded as the protection scope of the present invention.
