Technical Field

[0002] In today's production activities, especially in bridge and shipbuilding, partitions are widely used as workpieces. Metal partitions are generally produced by welding. Due to the complex welding process, metal partitions are usually produced by manual welding. However, manual welding is inefficient and the welding quality is unstable, resulting in low production efficiency and low production quality.

[0003] Later, some equipment capable of welding metal partitions appeared. These equipment can effectively improve the production efficiency and quality of metal partitions. However, these devices usually fix the metal partitions inside the equipment, and then use a movable welding machine to weld the edges of the metal partition strips, such as the partition welding robot welding machine disclosed in the Chinese invention patent application number 202211283486.5. However, the length of the equipment is limited, and the travel range of the welding machine is also limited. Therefore, these welding equipment have strict requirements on the length of the metal partition, and it will be inconvenient to weld if the length is slightly larger. If it is necessary to use these equipment to weld metal partitions with longer lengths, technicians need to use equipment such as cranes to shift and fix the metal partitions multiple times during the welding process before they can complete the welding of the longer metal partitions. Therefore, the current metal partition welding equipment has shortcomings such as low adaptability, low production efficiency when welding longer partitions, and insufficient quality of finished products. Summary of the Invention

Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them.

[0049] like Figures 1 to 15 As shown, a metal partition 10 welding device includes a frame 1 and a partition supporting structure 2, a partition limiting structure 3, a conveying device 4, a stopping device 5 and a welding device 6 arranged on the frame 1; the partition limiting structure 3 includes two side limiting structures 31 respectively arranged on both sides of the partition supporting structure 2, and a feeding channel 7 for the metal partition 10 to pass through is formed between the two side limiting structures 31; the conveying device 4 includes a conveying drive device 42 and a conveying member 41 connected by transmission, and the conveying member 41 is arranged on the peripheral side of the feeding channel 7, and the conveying The feeding member 41 can squeeze the metal partition 10 and drive it to move along the feeding channel 7; the stopping device 5 includes a stopping drive device 52 and a stopping member 53 that are transmission-connected. The stopping drive device 52 can move the stopping member 53 until at least part of it is facing the feeding channel 7 to stop the metal partition 10; the welding device 6 includes a welding machine 61 arranged next to the partition supporting structure 2. After the stopping member 53 stops the metal partition 10, the welding end 611 of the welding machine 61 faces the metal partition 10, and can weld at least one welding edge of the metal partition 10.

[0050] The metal separator 10 welding apparatus of this embodiment uses a conveying device 4 to transport the metal separator 10, allowing the metal separator 10 to move relative to the frame 1. The metal separator 10's weld edges are then positioned and welded using a stop device 5 and a welding device 6. Compared to the prior art, the metal separator 10 welding apparatus of this embodiment does not require multiple assembly and disassembly of the metal separator 10, even when welding longer metal separators 10. This facilitates the processing of metal separators 10 of various lengths, improves the stability of the finished product quality, and enhances production efficiency.

[0051] refer to Figures 1 to 3The metal separator 10 processed in this embodiment includes six metal plates, including a first metal plate 1011, a second metal plate 1012, a third metal plate 1013, a fourth metal plate 1014, a fifth metal plate 1015, and a sixth metal plate 1016. The first metal plate 1011, the second metal plate 1012, and the third metal plate 1013 are integrally formed by bending. The fourth metal plate 1014, the fifth metal plate 1015, and the sixth metal plate 1016 are then added to form four first weld edges 1021, four second weld edges 1022, and two third weld edges 1023.

[0052] Before placing the metal separator 10 in the welding equipment, the four first weld edges 1021 are manually welded. Then, the second weld edge 1022 and the third weld edge 1023 are spot welded, i.e., pre-welded, to initially form the structure of the metal separator 10. Because the first weld edges 1021 are relatively short, manual welding is less likely to result in quality and efficiency issues.

[0053] When placing the metal partition 10 on the partition supporting structure 2, the metal partition 10 should be in a posture with the second metal plate 1012 at the bottom, the fourth metal plate 1014 at the top, the fifth metal plate 1015 at the front, and the sixth metal plate 1016 at the back. The positions of the fifth metal plate 1015 and the sixth metal plate 1016 are interchangeable.

[0054] In some specific embodiments, reference Figure 4 、 Figure 5 and Figure 8 The conveying member 41 is a roller 411, which is rotatably connected to the frame 1, and its rotation axis extends longitudinally. The conveying device 4 includes multiple rollers 411, and multiple rollers 411 are distributed on both sides of the partition supporting structure 2. The rollers 411 distributed on both sides of the partition supporting structure 2 are respectively referred to as the first roller 4111 and the second roller 4112. The multiple first rollers 4111 and the multiple second rollers 4112 are arranged along the extension direction of the partition supporting structure 2. During conveying, the metal partition 10 is at least partially located in the feeding channel 7, and the first roller 4111 and the second roller 4112 squeeze the metal partition 10. The conveying drive device 42 is connected to the first roller 4111 and the second roller 4112 to drive the metal partition 10 to move along the feeding channel 7.

[0055] Specifically, multiple first rollers 4111 are evenly spaced, and multiple second rollers 4112 are evenly spaced. When the metal separator 10 enters the feed channel 7, the first rollers 4111 and second rollers 4112 on either side of the feed channel 7 press against the metal separator 10. The conveying drive 42 is in transmission connection with the first rollers 4111, driving the first rollers 4111 to rotate. Friction forces cause the metal separator 10 to move along the feed channel 7.

[0056] Furthermore, the plurality of first rollers 4111 and the plurality of second rollers 4112 are aligned one by one.

[0057] In some other embodiments, the conveying member 41 may be in other forms such as rollers, as long as it can drive the metal partition 10 to move along the feeding channel 7 .

[0058] In some other embodiments, a driven roller 43 is provided between adjacent rollers 411 , and the extension direction of the driven roller 43 is consistent with that of the roller 411 . The driven roller 43 is close to the lower side of the feeding channel 7 .

[0059] In some specific embodiments, reference Figure 5 The frame 1 includes a roller mounting frame 11, and a plurality of rollers 411 are rotatably connected to the roller mounting frame 11. A conveying drive device 42 is provided on the upper side of the roller mounting frame 11. The conveying drive device 42 includes a conveying drive motor and a conveying transmission structure. The axis of the conveying drive motor's rotating shaft is in the same or opposite direction as the feeding direction of the feeding channel 7. The conveying transmission structure is in driving connection with the rotating shaft of the conveying drive motor. The conveying drive motor drives the rollers 411 to rotate through the conveying transmission structure.

[0060] Specifically, the conveyor transmission structure includes a transmission rod, which is fixedly mounted coaxially with the shaft of the conveyor drive motor. Multiple first rollers 4111 are connected to the transmission rod. When the conveyor drive motor is activated, the transmission rod rotates, driving the multiple transmission members to rotate synchronously, thereby driving the multiple first rollers 4111 to rotate synchronously and in the same direction. The transmission between the transmission rod and the first rollers 4111 can be achieved through a bevel gear module or a worm gear module, as long as the rotation of the conveyor drive motor shaft is converted into rotation of the first rollers 4111.

[0061] In some specific embodiments, reference Figure 8 The two side limiting structures 31 are respectively referred to as a first side limiting structure 311 and a second side limiting structure 312 . The first side limiting structure 311 includes a plurality of first rollers 4111 , and the second side limiting structure 312 includes a plurality of second rollers 4112 .

[0062] Since the first roller 4111 and the second roller 4112 are respectively arranged on both sides of the feeding channel 7, they can limit the metal partition 10 from moving or tipping over to both sides. Therefore, the first roller 4111 and the second roller 4112 serve as the conveying member 41 and also as a component of the side limiting structure 31.

[0063] In some specific embodiments, reference Figure 9 The stop driving device 52 includes a stop fixing part 521 and a stop moving part 522 which are transmission-connected. The stop fixing part 521 is fixedly arranged on the side of the partition supporting structure 2. The stop member 53 is plate-shaped. The stop member 53 is arranged on the stop moving part 522 and extends longitudinally. During transportation, the stop member 53 is located between two adjacent rollers 411. During stopping, the stop driving device 52 drives the stop member 53 to move in a direction perpendicular to the feeding channel 7 so that at least part of it is facing the feeding channel 7.

[0064] Specifically, the stop drive device 52 is a stop drive cylinder, the cylinder body of the stop drive cylinder is the stop fixed portion 521, and the piston rod of the stop drive cylinder is the stop moving portion 522. The cylinder body is fixed on the frame 1, and the stop member 53 is fixed on the piston rod.

[0065] Furthermore, a stop mounting bracket 51 is provided on the frame 1. The stop mounting bracket 51 is located on the side of the feed channel 7 where the first roller 4111 is provided, corresponding to the middle of the partition support structure 2. A stop driving device 52 is provided on the stop mounting bracket 51, and a stop member 53 is located between two adjacent second rollers 4112.

[0066] A “slider-guide rail” structure is further provided between the stopping member 53 and the stopping mounting frame 51 to ensure that the stopping member 53 moves in a horizontal direction perpendicular to the feeding direction of the feeding channel 7 .

[0067] In some specific embodiments, reference Figure 9 The metal partition 10 welding equipment includes two stopping devices 5, which are arranged along the extension direction of the feeding channel 7. The two stopping devices 5 are respectively called the front stopping device and the rear stopping device, which are respectively used to stop the metal partition 10 at the front and rear sides of the metal partition 10.

[0068] Specifically, the interval between two adjacent first rollers 4111 is called the roller 411 interval, the stop member 53 of the front stop device and the stop member 53 of the rear stop device are respectively called the front stop member 531 and the rear stop member 532, the front stop member 531 and the rear stop member 532 are respectively located in the interval between two adjacent rollers 411, and the rear stop member 532 is located on the front side of the front stop member 531.

[0069] Since the front stop device and the rear stop device are both set on the stop mounting frame 51, if the front stop member 531 is located in front of the rear stop member 532, it will hinder the welding machine 61 from aligning with the second welding edge 1022 of the metal partition 10. Therefore, the rear stop member 532 is set in front of the front stop member 531.

[0070] In some specific embodiments, reference Figure 4 The welding device 6 also includes a welding movable device 62, which is arranged next to the conveying device 4. The welding machine 61 is arranged on the welding movable device 62. After the stopping member 53 stops the metal partition 10, the welding movable device 62 drives the welding end 611 of the welding machine 61 to pass through the gap between the two adjacent rollers 411, so that the welding machine 61 can weld the metal partition 10.

[0071] Specifically, the welding movable device 62 is a three-axis movable device, and the welding machine 61 is arranged on the three-axis movable device. It can move along the feeding direction, longitudinal direction and perpendicular to the feeding direction of the feeding channel 7, so that the welding machine 61 in this embodiment can weld each welding edge of the metal partition 10.

[0072] In some other embodiments, the welding machine 61 is fixedly mounted on the frame 1 , and when the metal partition 10 is transported in the feeding channel 7 , the welding machine 61 can weld the third welding edge 1023 of the metal partition 10 .

[0073] In some specific embodiments, welding devices 6 are provided on both sides of the conveying device 4 .

[0074] The metal separator 10 has two third welding edges 1023, one on each side of the metal separator 10. Therefore, the welding devices 6 are provided on both sides of the conveying device 4, so that the two third welding edges 1023 can be welded simultaneously, which can improve efficiency.

[0075] In some other embodiments, only one welding device 6 is provided on the metal partition 10 welding equipment. After the third welding edge 1023 on one side of the metal partition 10 is welded, the metal partition 10 needs to be removed and reversed before being sent into the feeding channel 7 before the third welding edge 1023 on the other side can be welded.

[0076] In some specific embodiments, reference Figure 4 、 Figure 5 and Figure 6 The partition supporting structure 2 includes a plurality of supporting wheels 21 arranged in sequence. The supporting wheels 21 are rotatably connected to the frame 1 , and their rotation axes are perpendicular to the arrangement direction of the plurality of supporting wheels 21 .

[0077] The supporting wheel 21 is a driven wheel. When the first roller 4111 and the second roller 4112 transport the metal separator 10 , the supporting wheel 21 rotates along with the metal separator 10 , so that the transportation of the metal separator 10 is smoother.

[0078] In some specific embodiments, reference Figure 5 and Figure 7 The partition limiting structure 3 also includes a transmission-connected pressing drive device 81 and multiple pressing wheels 82. The multiple pressing wheels 82 are arranged in sequence and the arrangement direction is consistent with the extension direction of the partition supporting structure 2. The multiple pressing wheels 82 are located directly above the partition supporting structure 2. The pressing drive device 81 includes a transmission-connected pressing fixed part and a pressing moving part. The pressing wheel 82 is rotatably connected to the pressing moving part, and its rotation axis is perpendicular to the arrangement direction of the multiple pressing wheels 82. The pressing drive device 81 can drive the pressing wheel 82 to move longitudinally.

[0079] After the metal separator 10 is placed on the separator support structure 2, the pressing drive device 81 drives the pressing wheel 82 to move downward until the pressing wheel 82 presses the metal separator 10 onto the separator support structure 2. The arrangement of the pressing drive device 81 and the pressing wheel 82 can limit the upward movement of the metal separator 10 and press the metal separator 10 onto the pressing wheel 82, making the position of the metal separator 10 more stable during transportation and enabling it to be transported according to a predetermined movement route, which is beneficial to improving welding quality.

[0080] Specifically, the roller mounting frame 11 is provided with a press moving device 83, and the press driving device 81 on the frame 1 is arranged on the press moving device 83. The press moving device 83 can drive the press driving device 81 to move longitudinally to adapt to the height of different metal separators 10. The press driving device 81 is a press driving cylinder, the cylinder body of which is arranged on the press moving device 83, and the press wheel 82 is arranged on the piston rod of the press driving cylinder, and the piston rod of the press driving cylinder is located on the lower side of the cylinder body of the press driving cylinder.

[0081] Furthermore, the material pressing moving device 83 can be configured as a linear motor, or a material pressing drive motor can be combined with a screw transmission module to achieve adjustment of the longitudinal position of the material pressing drive cylinder.

[0082] In some other embodiments, the conveying member 41 is a pressing wheel 82 , and the conveying driving device 42 is in transmission connection with the pressing wheel 82 , driving the pressing wheel 82 to rotate, thereby driving the metal partition 10 to move.

[0083] In some specific embodiments, reference Figure 10, and also includes two supporting platforms. The frame 1 is arranged between the two supporting platforms. The two supporting platforms are respectively called the first supporting platform 91 and the second supporting platform 92. The first supporting platform 91, the frame 1 and the second supporting platform 92 are arranged along the feeding direction of the feeding channel 7. The supporting platforms are provided with a partition supporting structure 2, a pressing drive device 81 and a plurality of pressing wheels 82. The partition supporting structure 2 on the supporting platform is aligned with the partition supporting structure 2 on the frame 1.

[0084] Specifically, the supporting platform is provided with a plurality of supporting wheels 21, and the arrangement direction of the plurality of supporting wheels 21 is consistent with the extension direction of the feeding channel 7. A pressing mounting frame 911 is also provided on the supporting platform, and a pressing driving device 81 and a plurality of pressing wheels 82 are provided at the upper end of the pressing mounting frame 911, and the arrangement direction of the plurality of pressing wheels 82 is consistent with the extension direction of the feeding channel 7.

[0085] The pressing mounting frame 911 is also provided with a pressing moving device 83 , and the pressing driving device 81 on the supporting platform is provided on the pressing moving device 83 to adapt to metal partitions 10 of different heights.
