[0037] See also Figure 1 and Figure 2 , Figure 7A side plate welding device comprises two groups of welding hosts 100 arranged side by side, and the two groups of welding hosts 100 respectively have an upper electrode group 200, and a movable lower electrode group 300 is arranged on one of the welding hosts 100, and a fixed lower electrode group 400 is arranged on the other welding host 100, the movable lower electrode group 300 can approach or move away from the fixed lower electrode group 400, and the movable lower electrode group 300 and the fixed lower electrode group 400 respectively cooperate with the corresponding upper electrode group 200, the movable lower electrode group 300 and the fixed lower electrode group 400 are respectively provided with a positioning and clamping mechanism, and a supporting mechanism 600 is also arranged between the movable lower electrode group 300 and the fixed lower electrode group 400.

[0038] Specifically, in the present embodiment, two groups of side-by-side welding hosts 100 are provided, and upper electrode groups 200 are respectively provided at the upper ends of the two groups of welding hosts 100, a movable lower electrode group 300 is provided at the lower end of one group of welding hosts 100, and a fixed lower electrode group 400 is provided at the lower end of the other group of welding hosts 100, and the movable lower electrode group 300 can approach or move away from the fixed lower electrode group 400, and the two sides of the side platen can be welded simultaneously through the two groups of upper electrode groups 200, the movable lower electrode group 300 and the fixed lower electrode group 400, thereby improving the welding efficiency.

The side top plate is then placed on the top of the side table, and the side surfaces of the side table and the side top plate are clamped and positioned by the positioning and clamping mechanism. After positioning and clamping, the upper electrode group 200 moves downward to contact the side top plate, thereby completing the electrode welding between the side top plate and the side table, realizing automated welding, improving the welding efficiency between the side top plate and the side table, and ensuring its welding quality and safe production.

[0040] In addition, in order to ensure safe production, in this embodiment, guardrails 800 are provided on the outsides of the two groups of welding hosts 100 arranged side by side, and safety gratings 810 are provided on the guardrails 800 on both sides.

[0041] See also Figure 3In order to realize electrode welding of the opposite side platen, the upper electrode group 200 in this embodiment includes an upper electrode fixing seat 210, a pressurizing cylinder 220 and an upper electrode plate 230. The upper electrode fixing seat 210 is arranged at the upper end of the front side of the welding host 100, and the pressurizing cylinder 220 is installed on the top of the upper electrode fixing seat 210. The upper electrode plate 230 is connected to the output end of the pressurizing cylinder 220, and the pressurizing cylinder 220 can drive the upper electrode plate 230 to move downward. When the side table is supported and adjusted by the supporting mechanism 600, so that the inner walls on both sides of the side table are in contact with the movable lower electrode group 300 and the fixed lower electrode group 400 respectively, and the side top plate is placed on the top of the side table and positioned by the positioning and clamping mechanism, at this time, the pressurized cylinder 220 will drive the upper electrode plate 230 to move downward, so that the upper electrode plate 230 is in contact with the side top plate, thereby realizing electrode welding between the side top plate and the two sides of the side table, realizing automated welding, ensuring safe production, and improving welding efficiency.

[0042] See also Figure 4 In order to facilitate welding of side plates of different models and sizes, the welding equipment in this embodiment can move the movable lower electrode group 300 toward or away from the fixed lower electrode group 400 to match side plates of different widths. Therefore, the movable lower electrode group 300 includes a lower electrode fixing seat 310, a driving cylinder 320, a lower electrode moving plate 330, a lower electrode bracket 340 and a lower electrode plate 350. The lower electrode fixing seat 310 is arranged on the front side of the welding host 100. At the lower end, the lower electrode movable plate 330 is connected to the lower electrode fixed seat 310 through the slide rail 360, the driving cylinder 320 is installed on the lower electrode fixed seat 310 and connected to the lower electrode movable plate 330, the lower electrode bracket 340 is fixed on the lower electrode movable plate 330, and a lower electrode cylinder 370 is provided at the bottom of the lower electrode bracket 340, the lower electrode plate 350 is connected to the lower electrode cylinder 370, and the lower electrode cylinder 370 can drive the lower electrode plate 350 to move upward.

[0043] When welding the side platen, the side platen is placed on the support mechanism 600, and the support mechanism 600 adjusts the height position of the side platen. After the height position is adjusted, the inner wall of the top of the side platen will contact the lower electrode plate 350, and the driving cylinder 320 can drive the lower electrode moving plate 330 to move along the slide rail 360. When the lower electrode moving plate 330 moves, it will move with the lower electrode bracket 340, thereby adjusting the position of the lower electrode plate 350, so that the lower electrode plate 350 moves to the preset position and is aligned with the side of the side platen. The tops remain in contact with each other. After the position of the lower electrode plate 350 is adjusted, the side top plate is placed on the top of the side table, and the pressurized cylinder 220 of the upper electrode group 200 moves downward to make the upper electrode plate 230 contact one side of the side top plate. By simultaneously contacting the upper electrode plate 230 and the lower electrode plate 350, welding of the side table and one side of the side top plate is achieved. During welding, the lower electrode cylinder 370 drives the lower electrode plate 350 to move upward to make the lower electrode plate 350 contact closely with the side wall at the top of the side table, thereby ensuring the welding effect.

[0044] In the present embodiment, the lower electrode movable plate 330 is driven to move by driving the air cylinder 320, thereby driving the lower electrode cylinder 370 and the lower electrode plate 350 to move toward or away from the fixed lower electrode group 400, and then combined with the support mechanism 600 to adjust the height position of the side platen, thereby realizing welding of side plates and side top plates of different models and sizes, thereby making the welding equipment more versatile.

[0045] Likewise, see Figure 5 In order to realize electrode welding between the side table and the side top plate, the fixed lower electrode group 400 in this embodiment includes a lower electrode fixing seat 410, a lower electrode bracket 420 and a lower electrode plate 430.

The lower electrode plate 430 is connected to the lower electrode cylinder 440, and the lower electrode cylinder 440 can drive the lower electrode plate 430 to run upward. When the side platen is supported by the supporting mechanism 600, the top inner wall on the other side of the side platen will come into contact with the lower electrode plate 2430. At this time, the corresponding upper electrode group 200 moves downward to make the upper electrode plate 230 come into contact with the side top plate, thereby realizing electrode welding of the side platen and the other side of the side top plate. During welding, the lower electrode cylinder 2440 will also drive the lower electrode plate 2430 to rise upward, so that the lower electrode plate 2430 can come into close contact with the side platen, thereby ensuring the welding quality between the side platen and the side top plate.

[0046] See also Figure 6In order to ensure the welding quality, when the side table is supported by the supporting mechanism 600, the movable lower electrode group 300 and the fixed lower electrode group 400 are respectively in contact with the side table, and then the side top plate is placed on the top of the side table. After placement, the two need to be clamped and positioned to facilitate welding. Therefore, the positioning and clamping mechanism of the movable lower electrode group 300 and the fixed lower electrode group 400 in this embodiment includes two groups of positioning units 500, and the two groups of positioning units 500 are vertically arranged, and the positioning unit 500 includes a positioning cylinder 510 and a positioning plate 520, and the positioning plate 520 is connected to the output end of the positioning cylinder 510, and the positioning cylinder 510 drives the positioning plate 520 to move.

[0047] After the side top plate is placed, the positioning cylinders 510 in the two groups of positioning units 500 of the movable lower electrode group 300 will drive the positioning plates 520 to move, and the two adjacent side surfaces on one side of the side table plate and the side top plate will be positioned and clamped by the two groups of positioning plates 520. At the same time, the positioning cylinders 510 in the two groups of positioning units 500 of the fixed lower electrode group 400 will also drive the positioning plates 520 to move, and the two adjacent side surfaces on the other side of the side table plate and the side top plate will be positioned and clamped by the two groups of positioning plates 520, thereby realizing the clamping positioning between the side table plate and the side top plate, so that the side table plate and the side top plate will not be displaced during welding, thereby ensuring the welding quality.

[0048] In addition, the movable lower electrode group 300 and the fixed lower electrode group 400 in this embodiment can be distributed on the left / right or right / left according to the model of the side platform, and the lower electrode plate 1 350 and the lower electrode plate 2 430 are both contoured structures, which are contoured to the side shape of the side platform.

[0049] Finally, see Figure 4 and Figure 5In this embodiment, in order to facilitate welding of the side platen, the side platen will be supported by a support mechanism 600, and the support mechanism 600 includes a connecting bracket 610, a supporting cylinder 620 and a supporting plate 630. The connecting bracket 610 can be fixed to the movable lower electrode group 300 or the fixed lower electrode group 400.

The supporting cylinder 620 is arranged on the connecting bracket 610, and the supporting plate 630 is connected to the supporting cylinder 620, and the supporting cylinder 620 drives the supporting plate 630 to move up and down. During welding, the bottom of the side platen can be placed on the support plate 630 first, and then the support cylinder 620 drives the support plate 630 to move downward so that the top inner wall of the side platen contacts the lower electrode plate 1 350 of the movable lower electrode group 300 and the lower electrode plate 2 430 of the fixed lower electrode group 400, thereby supporting the side platen; of course, the top inner walls on both sides of the side platen can be directly placed on the lower electrode plate 1 350 of the movable lower electrode group 300 and the lower electrode plate 2 430 of the fixed lower electrode group 400 so that they contact each other, and then the support cylinder 620 drives the support plate 630 to move upward to support the bottom of the side platen, which can also support the side platen. The specific support process is not limited, so that side plates of different sizes and models can be supported, and the support process is diversified.

[0050] At the same time, in order to facilitate the workers to operate, in the present embodiment, suction cups 700 are respectively provided on the front sides of the movable lower electrode group 300 and the fixed lower electrode group 400. Before supporting the side platen, the side platen can be first adsorbed by the suction cups 700 to prevent it from falling, and then the supporting mechanism 600 is started to support the side platen. The side platen is first adsorbed by the suction cups 700, which can facilitate the subsequent work operations, thereby improving the convenience of the welding equipment.
