Description

Technical Field

[0001] This utility model relates to the field of metal sheet welding, and more specifically, it relates to a feeding and conveying device based on metal sheet welding. Background Technology

[0002] Metal sheet welding is a manufacturing process that joins two or more metal sheets together. It involves heating, pressurizing, or applying both simultaneously, causing the atoms in the sheets to diffuse and bond together, forming a permanent connection. Common welding methods include manual arc welding, gas shielded welding, and submerged arc welding. Before welding, the metal sheets must be cleaned, cut, and ground to remove surface impurities such as oil, rust, and oxides, ensuring weld quality. During welding, appropriate welding process parameters and materials must be selected based on the material, thickness, and welding location of the sheets. The welding area must be fixed to prevent movement or deformation of the sheets. After welding, the weld must undergo visual inspection and non-destructive testing to ensure that the weld quality and strength meet requirements.

[0003] The current method for welding metal sheets is as follows: the metal sheet is transported to a suitable position by a roller conveyor, then it is attracted and fixed by a suction cup on a robotic arm, and then the robotic arm moves it to a suitable position for welding. During the transmission process of the roller conveyor, the metal sheet is easily affected by the vibration of the roller conveyor and may shift slightly, resulting in deviations in the suction position of the suction cup in the later stage, ultimately leading to poor welding accuracy.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a feeding and conveying device based on metal sheet welding. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a feeding and conveying device based on metal sheet welding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding and conveying device based on metal sheet welding, including a roller conveyor and a support frame located at the bottom of the roller conveyor. The two ends of a single roller in the roller conveyor are connected to a reversing transmission assembly via connecting rods. The reversing transmission assembly adjusts the rotation direction to be perpendicular to the roller, thereby driving the operation of reciprocating mechanisms set on both sides of the roller conveyor. The two reciprocating mechanisms drive the movement of two push plates to correct the position of the transported metal sheet.

[0007] Preferably, the support frame includes columns that support the roller conveyor, and crossbars are fixedly connected between the columns to reinforce the overall structure of the support frame. The reciprocating mechanism is fixed to the crossbars via connecting plates.

[0008] Preferably, the reciprocating mechanism includes a housing fixed to the head of the connecting plate, and the surface of the housing facing the top of the roller conveyor is open. A bearing is embedded in the bottom of the housing, and a rotating rod is installed in the inner ring of the bearing. A disc is fixedly connected to the top of the rotating rod, and a transmission rod is rotatably connected to the bottom surface of the disc near the edge. The head of the transmission rod is rotatably connected to a moving plate that moves linearly relative to the housing. The surface of the moving plate is fixed to the push plate by a round rod.

[0009] Preferably, guide rails are fixedly connected to the two sides of the interior of the housing, and the two sides of the movable plate are slidably connected to the guide rails by sliders to maintain the linear movement of the movable plate.

[0010] Preferably, the reversing transmission assembly includes a bevel gear A fixed to the bottom of the rotating rod, and a bevel gear B fixed to the head of the connecting rod and meshing with the bevel gear A. The bevel gear A can only rotate once when the bevel gear B rotates several times.

[0011] Preferably, the height of the support frame is adjustable, thereby adjusting the height of the roller conveyor. Preferably, the column on the support frame has an N-shaped cross-section, with a through hole at the bottom for a screw to pass through. The bottom of the screw is fixedly connected to a base, and nuts are threaded onto the upper and lower sides of the outer wall of the screw at the bottom of the column. This is mainly for small-range height adjustment, and is not suitable for large-range height adjustment.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In operation, the roller conveyor of this utility model drives the connecting rod to rotate. The rotation direction of the connecting rod is adjusted to be perpendicular to the roller by a reversing transmission component, ultimately driving the reciprocating mechanisms set on both sides of the roller conveyor. The two reciprocating mechanisms drive two push plates to move simultaneously towards the middle or to both sides to correct the position of the transported metal sheet, thereby improving the welding accuracy. This solves the problem in the prior art where the metal sheet is easily affected by the vibration of the roller conveyor, resulting in small displacement and poor welding accuracy.

[0014] 2. The reciprocating mechanism of this utility model does not need to share a power source with the roller conveyor, which can straighten metal sheets without the need for an additional motor.

[0015] 3. The height of the support frame of this utility model can be adjusted, thereby adjusting the height of the roller conveyor and facilitating the use of the roller conveyor in conjunction with other equipment. Attached Figure Description

[0022] like Figure 1-4 As shown, this utility model provides a feeding and conveying device based on metal sheet welding, including a roller conveyor 1 and a support frame 2 located at the bottom of the roller conveyor 1. The two ends of a single roller in the roller conveyor 1 are connected to a reversing transmission assembly 4 through a connecting rod 3. The reversing transmission assembly 4 adjusts the rotation direction to be perpendicular to the roller, thereby driving the operation of the reciprocating mechanism 5 set on both sides of the roller conveyor 1. The two reciprocating mechanisms 5 drive the movement of two push plates 7.

[0023] In use, when the roller conveyor 1 (only a section of roller conveyor 1 is shown in the attached diagram) is running, the rollers within it will rotate, thereby driving the metal sheet to move gradually. At the same time, the rollers will also drive the connecting rod 3 to rotate. The rotation direction of the connecting rod 3 is adjusted to be perpendicular to the roller by the direction-changing transmission assembly 4, which ultimately drives the operation of the reciprocating mechanisms 5 set on both sides of the roller conveyor 1. The two reciprocating mechanisms 5 drive the two push plates 7 to move simultaneously to the middle or to both sides. The purpose of moving to both sides is to facilitate the movement of the metal sheet between the two push plates 7, and to move to the middle is to push the push plates 7 to the appropriate position (which is also the normal conveying position of the metal sheet) to correct the position of the metal sheet during transportation, thereby improving the welding accuracy. In this way, the metal sheet can be corrected without the need for an additional motor, resulting in low operating costs.

[0024] It should be noted that when metal sheets are placed on roller conveyor 1 for transportation, an appropriate distance needs to be left between each pair so as to match the reciprocating motion of push plate 7.

[0025] Furthermore, the support frame 2 includes columns 21 that support the roller conveyor 1. Crossbars 22 are also fixedly connected between the columns 21 to reinforce the overall structure of the support frame 2. The reciprocating mechanism 5 is fixed to the crossbars 22 through the connecting plate 6. Moreover, the height of the support frame 2 can be adjusted to adjust the height of the roller conveyor 1, making it easier for the roller conveyor 1 to be used in conjunction with other equipment. The specific structure for height adjustment is as follows: The cross-section of the column 21 on the support frame 2 is N-shaped, and a through hole is opened at the bottom for the screw 23 to pass through. The bottom of the screw 23 is fixedly connected to the base 24, and nuts 25 are threadedly connected to the upper and lower sides of the outer wall of the screw 23 at the bottom of the column 21.

[0026] When adjusting the height of the support frame 2, first lift the roller conveyor 1 and adjust it to an appropriate height. During this process, the base 24 is always pressed against the bottom surface due to gravity, and the screw 23 on it moves along the through hole on the column 21. After the height adjustment is completed, rotate the nuts 25 on both sides so that the two nuts 25 abut against the upper and lower sides of the bottom of the column 21, thereby fixing the height of the roller conveyor 1.

[0027] Furthermore, this utility model also provides the specific structure of the reciprocating mechanism 5 and the reversing transmission assembly 4: the reciprocating mechanism 5 includes a housing 51 fixed to the head of the connecting plate 6, and the surface of the housing 51 facing the top of the roller conveyor 1 is open. A bearing 52 is embedded and fixed at the bottom of the housing 51. A rotating rod 53 is installed in the inner ring of the bearing 52. A disc 54 is fixedly connected to the top of the rotating rod 53. A transmission rod 55 is rotatably connected to the bottom surface of the disc 54 near the edge. A moving plate 56 that moves linearly relative to the housing 51 is rotatably connected to the head of the transmission rod 55. Guide rails 57 are fixedly connected to both sides inside the housing 51. The two sides of the moving plate 56 are slidably connected to the guide rails 57 through sliders 58. The surface of the moving plate 56 is fixed to the push plate 7 through a round rod 59. The reversing transmission assembly 4 includes a bevel gear A41 fixed to the bottom of the rotating rod 53 and a bevel gear B42 fixed to the head of the connecting rod 3 and meshing with the bevel gear A41.

[0028] When the rollers on the roller conveyor 1 drive the connecting rod 3 to rotate, the connecting rod 3 drives the bevel gear A41 to rotate via the bevel gear B42. The bevel gear A41 then drives the rotating rod 53 to rotate, which in turn drives the inner ring of the bearing 52 to rotate. The inner ring of the bearing 52 rotates along with its outer ring, providing rotational support for the rotating rod 53. The rotating rod 53 drives the disk 54 to rotate, and the disk 54 drives the moving plate 56 to move via the transmission rod 55. The moving plate 56 drives the slider 58 to move back and forth. The slider 58 slides along the guide rail 57 to maintain the linear movement of the moving plate 56. The moving plate 56 drives the push plate 7 to move back and forth via the round rod 59. To achieve the straightening of the metal sheet, it should be noted that the reciprocating mechanisms 5 on both sides rotate in opposite directions, thus driving the two push plates 7 to move simultaneously towards the middle or to both sides. The diameter of the bevel gear A41 needs to be designed to be larger than that of the bevel gear B42, so that the bevel gear A41 can only rotate once while the bevel gear B42 rotates several times, in order to match the transmission speed of the metal sheet (if the bevel gear B42 rotates too fast, not only will the straightening effect be poor, but it will also easily obstruct the metal sheet. For example, if the two push plates 7 move towards the middle before the metal sheet reaches the push plate 7, it will easily obstruct the metal sheet).
