[0042] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] This embodiment provides a fully automated welding production line for ladder beams of size 500. Please refer to [link / reference]. Figure 1-8 As shown, it includes: a beam-raising device 100, which is equipped with: a beam-feeding mechanism 110 for conveying beams 500; a beam-lifting mechanism 120, which is spaced apart from the beam-feeding mechanism 110 for supporting the conveyed beams 500 to create a height difference of 600 between the beams 500; a beam-feeding mechanism 130, which is movably disposed between the beam-lifting mechanism 120 and the welding machine 300 for intermittently conveying two batches of beams 500 toward the welding machine 300; and an upper support device 200, which is equipped with: a support conveying mechanism. 210 is used to horizontally transport the support 600 to the rotating support mechanism 230; the rotating support mechanism 230 is located on one side of the support transport mechanism 210 and is used to receive the support 600 and rotate it to a vertical position; the upper support robot 240 is movably located between the rotating support mechanism 230 and the welding machine 300 and is used to transport the support 600 between the two batches of beams 500; the welding machine 300 is equipped with a double-layer welding gun or a vertically movable single-layer welding gun and is used to weld at least the two sides of the upper and lower connection points of the support 600 and beam 500.

[0044] Specifically, regarding the upper beam 500: First, the beam lifting mechanism 120 is spaced apart from the beam feeding mechanism 110 to lift both ends of the beam 500. The beam lifting mechanism 120 includes a cylinder and a bracket, with the cylinder and bracket being drively connected. The beam lifting mechanism 120 can be fixedly installed on the beam feeding mechanism 110 or horizontally slidably connected to the beam feeding mechanism 110. When a fixed connection is used, the beam feeding mechanism 110 can transport a batch of beams 500 that has been previously transported to the beam lifting mechanism 120. Then, the beam lifting mechanism 120 can lift the previously transported batch of beams 500 to a higher level. Next, the beam feeding mechanism 110 can lift the subsequent batch of beams 500. The beams are conveyed to the lifting mechanism 120, at which point a support height of 600 is formed between the two layers of beams 500. In addition, to facilitate the output of the lower layer beams, another set of beam lifting mechanisms 120 can be used to lift the next batch of beams to the lower layer at the same time, as long as a support height of 600 is formed between the upper and lower layers of beams 500. When a sliding connection is used, the lifting mechanism 120 can lift part of the beams on the beam feeding mechanism 110 to the upper layer, and then slide to the other part of the beams, so that the two layers of beams overlap vertically. Then, the upper and lower layers of beams 500 can be intermittently moved from the beam feeding mechanism 110 to the welding machine 300 through the beam feeding mechanism 130.

[0045] Regarding the upper support 600: the support conveying mechanism 210 horizontally outputs the support 600 to the rotating support mechanism 230, which is provided with rotating support slides or rotatable rotating support slots at intervals; wherein, the rotating support slide can achieve automatic rotation of the support 600 to achieve vertical setting by setting inclined slides and vertical slides, and the rotating support slot can receive and accommodate the support 600 through the slot, and then rotate it together to achieve vertical setting. The rotating support slot can be driven by multiple rotary cylinders one by one, or by a sprocket set, gear set or connecting rod transmission method, so as to realize the rotation transmission of multiple rotating support slots at the same time;

[0046] Then, the upper support robot 240 can transport the vertical support 600 to the welding machine 300 and position it between the two beams 500. The upper support robot 240 can transport the support 600 through a sliding connection. Multiple upper support robots 240 can be connected to at least one slide block through a connector, thereby achieving sliding in at least one direction. For sliding in two directions, such as telescopic support picking and moving support delivery, a double-layer slide block can be used, or a single slide block can be connected to multiple upper support robots 240 through a telescopic cylinder. The upper support robot 240 can be gripped by a finger cylinder, and the rotating support mechanism 230 is provided with a gripping slot. Then, the welding machine 300 welds the upper and lower connection points of the support 600 and beam 500 using a double-layer welding gun, or a single-layer welding gun can be used. The single-layer welding gun is vertically movable and located in the welding machine 300. Moreover, each welding gun can have a double-headed structure, which can weld both sides of the connection point. In addition, it includes an output device 400 for conveying the ladder beam 500 out.

[0047] Therefore, the beam 500 and the support 600 can be vertically transported to the welding machine 300 through the upper beam device 100 and the upper support device 200 respectively. Moreover, the two sides of the connection between the support 600 and the beam 500 can be welded simultaneously through a single-layer moving or double-layer double-head welding gun. The entire welding process does not require flipping the beam and can be completed by a single welding machine, which significantly improves production efficiency.

[0048] In this embodiment, the beam conveying mechanism 110 includes: a first beam conveying chain 111, which consists of multiple chains arranged at intervals, and the conveying direction of the first beam conveying chain 111 is perpendicular to the length direction of the beam 500.

[0049] Specifically, the beam conveying mechanism 110 adopts a chain conveying structure. The first beam conveying chain 111 is set in parallel intervals, which can accurately convey the beam 500 perpendicular to the chain direction.

[0050] In this embodiment, please refer to Figure 2 As shown, the beam loading device 100 also includes an interval arrangement mechanism 140, the output end of which is connected to the input end of the beam feeding mechanism 110, for arranging the beams 500 at intervals to the beam feeding mechanism 110.

[0051] Specifically, the interval arrangement mechanism 140 is used to arrange the beams 500 sequentially on the first beam conveyor chain 111, so that the upper and lower beams correspond one to one; wherein, the interval arrangement mechanism 140 can be a structure such as the rotating hook 142 alone, or it can be a structure combined with the inclined slide plate 141 described below.

[0052] In this embodiment, please refer to Figure 3-4As shown, the interval arrangement mechanism 140 includes: an inclined slide plate 141, the lower end of which is disposed at the input end of the beam feeding mechanism 110; and a rotating hook 142, which is spaced between the input end of the beam feeding mechanism 110 and the lower end of the inclined slide plate 141, for rotating to arrange the beams 500 from the inclined slide plate 141 to the beam feeding mechanism 110.

[0053] Specifically, the inclined slide plate 141 is used to automatically transport the beam 500 to the lower end, while the rotating hook 142 transports the beam 500 to the first beam conveyor chain 111 by rotation, thus completing the interval arrangement. The rotating hook 142 can be set on the rotating shaft of the first beam conveyor chain 111 or it can be set separately.

[0054] In this embodiment, please refer to Figure 2-3 As shown, the beam mounting device 100 further includes: an alignment mechanism 150; the alignment mechanism 150 is connected to the spacing arrangement mechanism 140, and is used to at least arrange the beams 500 in parallel to the spacing arrangement mechanism (140).

[0055] Specifically, the alignment mechanism 150 can be a structure consisting solely of the beam arranging component 151, or a structure combining the beam arranging component 151 with the second beam conveyor chain 152, or a structure combining the beam arranging component 151, the second beam conveyor chain 152, and the alignment assembly 153. The output end of the alignment mechanism 150 is connected to the high end of the inclined slide plate 141 for at least parallel placement of the beams 500. The alignment mechanism 150 can be composed of an inclined plane, a hinged blocking plate, and a cylinder. The cylinder pulls one end of the blocking plate, which moves the other end of the blocking plate relative to the lower end of the inclined plane to achieve release and blocking. Alternatively, a cylinder can be used alone as the blocking component, wherein the cylinder is set vertically or at an angle, and its output end is movable relative to the lower end of the inclined plane.

[0056] In this embodiment, please refer to Figure 2-3 As shown, the alignment mechanism 150 includes: beam placement arrangement members 151, which are spaced apart at the input end of the second beam conveyor chain 152 for placing the beams 500 parallel to the second beam conveyor chain 152; the second beam conveyor chain 152; the output end of the second beam conveyor chain 152 is connected to the spaced arrangement mechanism 140; and the end-aligning assembly 153, which is installed on one side of the beam feeding mechanism 110 and / or the second beam conveyor chain 152 for aligning the two ends of the beams 500.

[0057] Specifically, at least two beam-laying components 151 are used and are spaced apart. The beam-laying components 151 achieve parallel beam-laying by simultaneously releasing the beams 500. Meanwhile, the end-aligning component 153 is set on one side of the beam-feeding mechanism 110 and achieves alignment of the two ends of the beams 500 by pushing one end of the beams 500. The end-aligning component 153 can be a combination structure of a cylinder and a push plate.

[0058] In this embodiment, please refer to Figure 7-8 As shown, the support mechanism 210 includes: a support conveying chain 211, the conveying direction of the support conveying chain 211 is consistent with the length direction of the support 600; and a support push-out member 212, which is disposed on one side of the support conveying chain 211 and is used to push the support 600 from the support conveying chain 211 to the rotary support mechanism 230.

[0059] Specifically, the support 600 is output roughly parallel to the support conveyor chain 211, i.e., the upper bearing surface of the chain. The output direction of the support ejector 212 is perpendicular to the chain, which can push the support 600 to the adjacent rotating support mechanism 230. The support ejector 212 can adopt a combination structure of cylinder and push plate.

[0060] In this embodiment, please refer to Figure 2-3 As shown, the support mechanism 210 also includes a pusher arrangement 220, which is disposed at the input end of the support conveyor chain 211, and the pushing direction of the output end of the pusher arrangement 220 is consistent with the conveying direction of the support 600.

[0061] Specifically, the output end of the pusher arrangement 220 is aligned with the conveying direction of the chain, and can further push the support 600 in the conveying direction. This allows the supports 600 to be evenly spaced along the length of the chain, so that the supports 600 correspond one-to-one with the rotating support 600 slides or rotating support 600 grooves spaced apart by the rotating support mechanism 230. The pusher arrangement 220 can be a combination of a cylinder and a push rod, or a reciprocating linkage structure coaxially connected to the support conveyor chain 211.

[0062] In this embodiment, please refer to Figure 2 and Figure 7 As shown, the upper support device 200 also includes a vibratory support feeder 250; the vibratory support feeder 250 is connected to the support conveying mechanism 210 and is used to convey the support 600 to the support conveying mechanism 210.

[0063] Specifically, the vibratory support machine 250 includes a vibratory support feeding mechanism 600 and an inclined conveying mechanism for connecting the support feeding mechanism 210.

[0064] In this embodiment, please refer to Figure 7 As shown, the welding machine 300 also includes a clamping mechanism 310, which is spaced apart from the welding machine 300. The clamping mechanism 310 is movable relative to the connection between the support 600 and the beam 500, and is used to clamp the connection to assist welding.

[0065] Specifically, the clamping mechanism 310 adopts a structure similar to a clamp. The clamping head of the clamping mechanism 310 consists of two semi-circular rings extending to one side. One handle of the clamping mechanism 310 is fixed to the welding machine 300, while the other handle can be clamped and released via a cylinder connected to it. Simultaneously, it can be moved via another cylinder, a slide, and a connecting frame arranged parallel to the beam feeding direction. The cylinder is mounted on the welding machine and drivenly connected to the slide, which can be slidably connected to the welding machine and connected to multiple clamping mechanisms 310 via the connecting frame, thereby realizing the movement of the clamping mechanism 310 and ultimately achieving the operation of moving, clamping, releasing, and resetting the clamping mechanism 310. Furthermore, this clamping mechanism 310 can replace welding molds, enabling moldless welding.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
