[0041] Refer to the following Figures 1-12 The following describes an automatic feeding mechanism for welding a moving iron unit provided by the present invention.

[0042] An automatic loading mechanism for welding a moving iron unit is suitable for conveying materials during welding of the moving iron unit, comprising a conveyor frame on which a conveyor belt 100 is provided, and one side of the conveyor frame is a loading area, the conveyor frame is provided with a positioning area, the loading area is used to convey materials for making the moving iron unit, and the positioning area is used to position the materials to facilitate the subsequent manufacture of the moving iron unit. The moving iron unit is composed of multiple intermediate iron sheets 190 and two end iron sheets 170. The intermediate iron sheets 190 and the end iron sheets 170 are both rectangular frame-shaped. Rectangular grooves are opened on the two end faces of the intermediate iron sheet 190 and the end face of the end iron sheet 170 close to the intermediate iron sheet 190. The rectangular grooves are also rectangular frame-shaped. Rectangular welding wires 180 are installed in the rectangular grooves. The multiple intermediate iron sheets 190 are stacked on each other and the end iron sheets 170 are stacked at both ends of the multiple intermediate iron sheets 190 and then heated to melt the rectangular welding wires 180 in the rectangular grooves, thereby connecting the multiple intermediate iron sheets 190 and the end iron sheets 170 to form a moving iron unit. In the prior art, a robotic arm is used to transport multiple intermediate iron sheets 190, two end iron sheets 170 and rectangular welding wires 180, which easily causes the rectangular welding wires 180 to deform, and the assembly efficiency of the robotic arm is slow.

[0043] Based on this, the present invention distributes two first conveying pipes 110, a plurality of second conveying pipes 120 and a plurality of third conveying pipes 130 in the vertical direction along the conveying direction of the conveyor belt 100 in the loading area. The plurality of second conveying pipes 120 and the plurality of third conveying pipes 130 are alternately arranged between the two first conveying pipes 110, and the first conveying pipe 110 is used to convey the end iron sheet 170 to the positioning area, the second conveying pipe 120 is used to convey the rectangular welding wire 180 to the positioning area, and the third conveying pipe 130 is used to convey the intermediate iron sheet 190 to the positioning area. It should be noted that, assuming that four intermediate iron sheets 190 are required to make a moving iron unit When there are two end iron sheets 170, the number of second conveying tubes 120 is five, and the number of third conveying tubes 130 is four. Each time, the two first conveying tubes 110 respectively convey the end iron sheets 170, the five second conveying tubes 120 respectively convey the rectangular welding wire 180, and the four third conveying tubes 130 respectively convey the middle iron sheets 190, so as to simultaneously load the materials required to make a moving iron unit, and the first conveying tube 110, the second conveying tube 120 and the third conveying tube 130 can continuously load materials, thereby greatly improving the loading speed of the end iron sheets 170, the middle iron sheets 190 and the rectangular welding wire 180.

[0044] At the same time, a clamping assembly is also provided on the conveyor belt 100, which is used to clamp the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 transported by the first conveying pipe 110, the second conveying pipe 120 and the third conveying pipe 130 together. The conveyor belt 100 drives the clamping assembly to move. During the movement, the clamping assembly positions the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 in the positioning area. It should be noted that a plurality of clamping assemblies are provided on the conveyor belt 100, and the plurality of clamping assemblies are evenly distributed on the conveyor belt 100. When the conveyor belt 100 rotates, the clamping assembly continuously passes through the loading area to clamp the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190, thereby improving the manufacturing efficiency of the moving iron unit.

[0045] Specifically, the first conveying pipe 110, the second conveying pipe 120 and the third conveying pipe 130 in the embodiment of the present invention are respectively connected to the first conveyor 111, the second conveyor 121 and the third conveyor 131. The first conveyor 111, the second conveyor 121 and the third conveyor 131 each include a loading barrel and a conveyor (not shown in the figure). The loading barrel is used to hold the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190, and the conveyor is used to input these end iron sheets 170, the rectangular welding wire 180 and the middle iron sheet 190 into the first conveying pipe 110, the second conveying pipe 120 and the third conveying pipe 130.

[0046] More specifically, Figure 1 and Figure 3 As shown, the ends of the first conveying pipe 110, the second conveying pipe 120 and the third conveying pipe 130 in the present invention are perpendicular to the horizontal plane, and have an opening 140 on the end facing the conveying direction of the conveyor belt 100. The internal shape of the first conveying pipe 110 is the same as the cross-sectional shape of the end iron sheet 170 in the length or width direction, the internal shape of the second conveying pipe 120 is the same as the cross-sectional shape of the rectangular welding wire 180 in the length or width direction, and the internal shape of the third conveying pipe 130 is the same as the cross-sectional shape of the middle iron sheet 190 in the length or width direction, thereby ensuring that the end iron sheet 170, the middle iron sheet 190 and the rectangular welding wire 180 conveyed to the opening 140 are in the same state, that is, in a vertical state. Taking the middle iron sheet 190 as an example, when the middle iron sheet 190 inside the third conveying tube 130 is conveyed to the opening 140 at the end of the third conveying tube 130, the middle iron sheet 190 is just located at the opening 140. Similarly, the end iron sheet 170 and the rectangular welding wire 180 are respectively located on the opening 140 of the first conveying tube 110 and the second conveying tube 120, and the positions of the two end iron sheets 170, the five rectangular welding wires 180 and the four middle iron sheets 190 correspond one to one, thereby facilitating the clamping positioning of the clamping assembly.

[0047] In a further embodiment, the clamping assembly of the present invention includes two positioning rods 240, an abutment ring 270 and a support plate 220. A horizontal plate 210 is connected to the conveyor belt 100, and the support plate 220 is connected to the horizontal plate 210. The support plate 220 can slide on the horizontal plate 210 in a direction perpendicular to the conveying direction of the conveyor belt 100. A rotating disk 230 is rotatably provided on the support plate 220. Two positioning rods 240 are connected to the rotating disk 230. The two positioning rods 240 are parallel to each other and vertically connected to the rotating disk 230. When the rotating disk 230 rotates, the two positioning rods 240 are driven The positioning rods 240 rotate synchronously, and the distance between the two positioning rods 240 is just equal to the length of the internal width direction of the end iron sheet 170 and the middle iron sheet 190, so that when the plane formed by the two positioning rods 240 is a horizontal plane, the end iron sheet 170 and the middle iron sheet 190 can be positioned, and at the same time, the rectangular welding wire 180 between the end iron sheet 170 and the middle iron sheet 190 and the rectangular welding wire 180 between adjacent middle iron sheets 190 are preliminarily positioned, and the abutment ring 270 is fixedly set on the horizontal plate 210, and the axis of the abutment ring 270 coincides with the axis of the rotating disk 230.

[0048] It can be understood that when the end iron sheet 170, the middle iron sheet 190 and the rectangular welding wire 180 are all located at the position of the opening 140, the support plate 220 drives the two positioning rods 240 to move toward the end iron sheet 170, and the plane formed by the two positioning rods 240 in the initial state is an inclined plane or a vertical plane, as long as it is not a horizontal plane. The two positioning rods 240 first pass through the abutment ring 270 and then gradually penetrate into the middle of the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190, and since the horizontal plate 210 is connected to the conveyor belt 100, the conveyor belt 100 drives the horizontal plate 210 to move, and the horizontal plate 210 drives the support plate 220 to move synchronously, and the two positioning rods 240 on the support plate 220 pull the two end iron sheets 170, the five rectangular welding wires 180 and the four middle iron sheets 190 out of the opening 140.

[0049] In order to make the positioning rod 240 have a positioning function, a positioning circular plate 241 is coaxially and fixedly provided on one end of the two positioning rods 240 away from the support plate 220. The diameter of the positioning circular plate 241 is larger than the diameter of the positioning rod 240. At the same time, the diameter of the positioning circular plate 241 is smaller than the space between the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190, so that the two positioning circular plates 241 can pass through the middle position of the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190. When the two positioning circular plates 241 pass through the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190, the rotating disk 230 on the support plate 220 rotates around its own axis to drive the two positioning rods 240 to revolve so that the plane where the two positioning rods 240 are located is in a horizontal state, and the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 are in a horizontal state. Under the action of gravity, its interior contacts the outer periphery of the two positioning rods 240, and the two positioning rods 240 are located at the two corners in the width direction of the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190, thereby positioning the end iron sheet 170 and the middle iron sheet 190, and preliminarily positioning the rectangular welding wire 180. Subsequently, the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 need to be clamped. When the support plate 220 drives the two positioning rods 240 close to the abutment ring 270, the positioning circular plate 241 on the two positioning rods 240 will drive the end iron sheet 170 and all the middle iron sheets 190 and the rectangular welding wire 180 close to the abutment ring 270. After the abutment ring 270 abuts against the other end iron sheet 170, the two end iron sheets 170, the four middle iron sheets 190 and the five rectangular welding wires 180 are clamped together.

[0050] It should be noted that at this time, the rectangular welding wire 180 contacts the outer periphery of the positioning rod 240 under the action of gravity and cannot enter the rectangular groove. Therefore, a plurality of supporting protrusions 250 elastically distributed along the axial direction of the positioning rod 240 are provided on the positioning rod 240. The supporting protrusions 250 will support the five rectangular welding wires 180 to a certain height so that the rectangular welding wires 180 just correspond to the position of the rectangular groove, and then the rectangular welding wires 180 can be pushed into the rectangular groove. The plurality of supporting protrusions 250 in this embodiment have two parts, one part is the axis One part is slidingly arranged inside the positioning rod 240, and the other part extends out of the positioning rod 240. The width of the part where the multiple support protrusions 250 extend out of the positioning rod 240 is smaller than the diameter of the rectangular welding wire 180, and the multiple support protrusions 250 are arranged at a position close to the positioning circular plate 241. An elastic member 251 is arranged between adjacent support protrusions 250. The elastic member 251 is a compression spring. The elastic member 251 is used to maintain the distance between the multiple support protrusions 250, so that the multiple support protrusions 250 can respectively correspond to the corners inside each rectangular welding wire 180.

[0051] It can be understood that in the initial state, the multiple support protrusions 250 are located at the position where the two positioning rods 240 are close to each other. At this time, the multiple support protrusions 250 do not affect the two positioning rods 240 passing through the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190, and do not affect the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 sliding on the periphery of the two positioning rods 240. When the end iron sheet 170, the middle iron sheet 190 and the rectangular welding wire 180 abut against each other, and the positioning circular plate 241 abuts against the end iron sheet 170, although the multiple support protrusions 250 are still located at the position where the two positioning rods 240 are close to each other, the corner position inside each rectangular welding wire 180 has corresponded one-to-one with each support protrusion 250. At this time, the two positioning rods 240 The positioning rod 240 can rotate around its own axis to make multiple support protrusions 250 contact the inner corners of the rectangular welding wire 180, and push the rectangular welding wire 180 to correspond to the position of the rectangular groove. Since the width of the support protrusion 250 of the present invention is smaller than the diameter of the rectangular welding wire 180, when the adjacent middle iron sheets 190 and the rectangular grooves between the end iron sheet 170 and the middle iron sheet 190 are close to each other, a part of the rectangular welding wire 180 can enter the rectangular groove, and then when the support protrusion 250 is separated from the rectangular welding wire 180, it can be ensured that the rectangular welding wire 180 will not completely separate from the rectangular groove. Since the cross-section of the rectangular welding wire 180 is circular, when the rectangular grooves are close to each other, the rectangular welding wire 180 can be completely pushed into the rectangular groove to prevent the rectangular welding wire 180 from being stuck outside the rectangular groove.

[0052] It should be noted that the elastic members 251 provided between the multiple support protrusions 250 of the present invention can enable the distance between the multiple support protrusions 250 to adapt to the changes in the spacing between adjacent intermediate iron sheets 190 and between the end iron sheet 170 and the intermediate iron sheet 190. If the distance between the support protrusions 250 cannot change, it will cause the adjacent intermediate iron sheets 190 and between the end iron sheet 170 and the intermediate iron sheet 190 to be unable to contact each other.

[0053] In a further embodiment, the present invention can make the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 abut against each other after the two positioning rods 240 pass through the end iron sheet 170, the middle iron sheet 190 and the rectangular welding wire 180. Specifically, to achieve the above function, the present invention hinges the horizontal plate 210 on the conveyor belt 100, and the horizontal plate 210 can rotate around the hinge position, such as Figure 3 、 Figure 4 and Figure 5As shown, when the two positioning rods 240 pass through the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 and separate them from the opening 140, the other end of the horizontal plate 210 will move upward around the hinge position, so that the end of the two positioning rods 240 close to the positioning circular plate 241 tilts downward, so that the end iron sheet 170, the middle iron sheet 190 and the rectangular welding wire 180 can abut against each other under the action of gravity, and then the support plate 220 slides on the horizontal plate 210, thereby driving the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 to move toward the abutment ring 270. When the end iron sheet 170 abuts against the abutment ring 270, the horizontal plate 210 returns to a horizontal state.

[0054] Specifically, such as Figure 4 and Figure 9 As shown, in order to enable the horizontal plate 210 to rotate around the hinge position, a plurality of connecting plates 200 are provided on the conveyor belt 100 in this embodiment, and a telescopic cylinder 260 is provided on each of the plurality of connecting plates 200. One end of the telescopic cylinder 260 is hinged to an end of the connecting plate 200 away from the hinge position, and the other end of the telescopic cylinder 260 is hinged to an end of the horizontal plate 210 away from the hinge position. When the telescopic cylinder 260 is extended, it can push the horizontal plate 210 to rotate around the hinge position, thereby allowing the horizontal plate 210 to tilt.

[0055] It can be understood that by rotating the hinged horizontal plate 210, the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 can slide on the two positioning rods 240 and slide until the end iron sheet 170 abuts against the positioning circular plate 241, so that the support protrusion 250 on the positioning rod 240 can correspond to the position of the rectangular welding wire 180.

[0056] In a further embodiment, a first drive assembly and a second drive assembly are provided on the conveyor belt 100 of the present invention, the first drive assembly is used to drive the support plate 220 to slide in a direction perpendicular to the conveying direction of the conveyor belt 100, and the second drive assembly has a first drive part and a second drive part, the first drive part is used to drive the rotating disk 230 to rotate around its own axis, and the second drive part is used to drive the two positioning rods 240 to rotate around their own axis.

[0057] Specifically, such as Figure 10 and Figure 11As shown, the first drive assembly includes a first drive motor 300 and a screw 310. The first drive motor 300 is fixedly arranged on the horizontal plate 210. The horizontal plate 210 is provided with a slide groove 211 extending perpendicular to the conveying direction of the conveyor belt 100. The screw 310 is rotatably arranged in the slide groove 211. The rotating shaft of the first drive motor 300 is coaxially and fixedly connected to the screw 310. A slider (not shown in the figure) is fixedly arranged at the bottom of the support plate 220. The slider is slidably arranged in the slide groove 211, and the slider is spirally connected to the screw 310. When the first drive motor 300 drives the screw 310 to rotate, it can drive the support plate 220 to slide along the conveying direction perpendicular to the conveyor belt 100 through the slider and the slide groove 211, so that the support plate 220 drives the two positioning rods 240 to approach or move away from the abutment ring 270.

[0058] More specifically, the first driving part of the second driving assembly includes a second driving motor 320 and a first transmission gear 330. The second driving motor 320 is fixedly arranged on the support plate 220, and the first transmission gear 330 is coaxial and fixedly connected to the rotating disk 230. The rotating shaft of the second driving motor 320 is engaged with the first transmission gear 330. When the rotating shaft of the second driving motor 320 rotates, it drives the first transmission gear 330 to rotate. The first transmission gear 330 drives the rotating disk 230 to rotate and then drives the two positioning rods 240 to revolve around the axis of the rotating disk 230 itself.

[0059] like Figure 11 As shown, the second driving part of the present invention includes a third driving motor 340, a second transmission gear 350, a gear ring 360 and two friction wheels 370. The two friction wheels 370 are coaxial and fixedly connected to the outer periphery of the two positioning rods 240. The outer peripheries of the two friction wheels 370 are in friction contact and are located inside the support plate 220. The two friction wheels 370 are rotatably set on the rotating disk 230 and the first transmission gear 330, while the second transmission gear 350 is coaxial and fixedly set on one of the two friction wheels 370. The gear ring 360 is rotatably set inside the support plate 220. The gear ring 360 is coaxial with the first transmission gear 330 and the rotating disk 230. 0 is meshed with the second transmission gear 350, and the third drive motor 340 in this embodiment is also fixedly set on the support plate 220, and the rotating shaft of the third drive motor 340 is meshed with the outer periphery of the gear ring 360. When the third drive motor 340 is started, it drives the gear ring 360 to rotate, and the gear ring 360 drives the second transmission gear 350 to rotate. The second transmission gear 350 drives one of the friction wheels 370 to rotate so that the two friction wheels 370 rotate synchronously. The two friction wheels 370 simultaneously drive the two positioning rods 240 to rotate around their own axes, thereby being able to push the support protrusions 250 on the two positioning rods 240 to the corner inside the rectangular welding wire 180.

[0060] It will be appreciated that the provision of the gear ring 360 ensures that the two positioning rods 240 can be driven by the third drive motor 340 to rotate about their own axes when they are rotated to any position. Furthermore, in this embodiment, the two positioning rods 240 require a relatively large driving force to be driven. Therefore, when the rotating disk 230 rotates, the second transmission gear 350 drives the gear ring 360 to rotate, thereby preventing the second transmission gear 350 from rotating relative to the gear ring 360 when the third drive motor 340 is not activated. In this embodiment, a limit ring (not shown) is provided on the end surface of the gear ring 360, and a limit slot (not shown) is provided in the support plate 220. The gear ring 360 is rotatably connected to the support plate 220 via the limit ring and the limit slot, thereby enabling the gear ring 360 to rotate about its own axis to drive the second transmission gear 350 to rotate.

[0061] It should be noted that, in the present invention, a welding area is also provided on the conveyor frame, and the welding area is used to weld the positioned end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 together. Specifically, the welding area is provided with a welding assembly (not shown in the figure), and the welding assembly can heat the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190, so that the rectangular welding wire 180 in the rectangular frame melts, thereby connecting the end iron sheet 170 and the middle iron sheet 190 together and completing the processing and manufacturing of the moving iron unit.

[0062] In a further embodiment, Figure 1 and Figure 2 As shown, one end of the two first conveying pipes 110 in the present invention is connected and connected to the first conveyor 111 together. An identification component 160 is provided at the connection position. The identification component 160 can identify the front and back sides of the end iron sheet 170 (the front side of the end iron sheet 170 has a rectangular groove, and the back side does not have a rectangular groove). Since the two end iron sheets 170 are respectively located at the two ends of the four intermediate iron sheets 190, the conveying states of the two end iron sheets 170 need to be opposite, that is, the side of the end iron sheet 170 with the rectangular groove faces the intermediate iron sheet 190. Therefore, the end iron sheet 170 conveyed by the first conveyor 111 will be identified by the identification component 160. If it is on the front side, it will pass directly. If it is on the back side, it will be pushed by the push rod 150 into the other first conveying pipe 110, thereby conveying the two end iron sheets 170 in different states to the two first conveying pipes 110 respectively.

[0063] It should be noted that the identification component 160 in this embodiment can be a visual sensor or other sensor that can identify the front and back sides of the end iron sheet 170, and the push rod 150 can be driven by other power sources such as a hydraulic cylinder. When the identification component 160 identifies the front or back side of the end iron sheet 170, it can send a signal to drive the push rod 150 to extend, thereby pushing the end iron sheet 170 into different first conveying pipes 110.

[0064] The specific working process of the automatic feeding mechanism for welding a moving iron unit provided by the present invention is described in combination with the above embodiments:

[0065] Conveying materials:

[0066] Start the first conveyor 111, the second conveyor 121 and the third conveyor 131. The first conveyor 111 is used to convey the two end iron sheets 170, the second conveyor 121 is used to convey the rectangular welding wire 180, and the third conveyor 131 is used to convey the middle iron sheet 190. The two end iron sheets 170, the rectangular welding wire 180 and the middle iron sheet 190 are all conveyed to the opening 140 position.

[0067] position:

[0068] The conveyor belt 100 drives the horizontal plate 210 to move to the position corresponding to the opening 140. At this time, the plane formed by the two positioning rods 240 on the support plate 220 is not a horizontal plane. Under the action of the first drive motor 300, the support plate 220 drives the two positioning rods 240 to pass through the abutment ring 270 and pass through the two end iron sheets 170, the rectangular welding wire 180 and the middle iron sheet 190. When the positioning circular plate 241 on the two positioning rods 240 passes through the last end iron sheet 170, the first drive motor 300 stops rotating, and then the conveyor belt 100 starts. The conveyor belt 100 drives the horizontal plate 210 to move so that the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 are separated from the opening 140, and the new end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 are transported in the first conveying pipe 110, the second conveying pipe 120 and the third conveying pipe 130 so that the next horizontal plate 210 moves to the corresponding position and stops, and the second drive motor 320 starts to drive the rotating disk 230 to rotate so that the two positioning rods 240 are on the same horizontal plane. At this time, the inner corners of the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 in the width direction are in contact with the outer periphery of the two positioning rods 240. Then, as shown in Figure 4, the telescopic cylinder 260 on the connecting plate 200 extends to push the horizontal plate 210 to rotate around the hinge position so that the support plate 220 on the horizontal plate 210 and the two positioning rods 240 are tilted. The end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 on the two positioning rods 240 slide along the positioning rod 240 under the action of gravity and stop after sliding until the end iron sheet 170 contacts the positioning circular plate 241 on the positioning rod 240. The position of the rectangular welding wire 180 corresponds one to one to the multiple support protrusions 250 at the positions close to each other on the positioning rods 240.

[0069] The third drive motor 340 is started, and the third drive motor 340 drives the gear ring 360 to rotate, and the gear ring 360 drives the second transmission gear 350 to rotate, and the second transmission gear 350 drives the two friction wheels 370 to rotate, thereby driving the two positioning rods 240 to rotate around their own axes, so that the multiple support protrusions 250 on the two positioning rods 240 gradually approach the corners inside the rectangular welding wire 180. With the support of the support protrusions 250, the height of the rectangular welding wire 180 increases to correspond to the position of the rectangular groove. At this time, the support protrusions 250 are located between the adjacent middle iron sheet 190 and the end iron sheet 170 and the middle iron sheet 190 to support the rectangular welding wire 180.

[0070] like Figure 5 and Figure 6 As shown, the first drive motor 300 then rotates in the opposite direction to drive the support plate 220 away from the abutment ring 270, and the positioning circular plates 241 on the two positioning rods 240 limit the relative movement of the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190. The two positioning rods 240 make the other end iron sheet 170 abut against the abutment ring 270. At this time, the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 are clamped. At the same time, the telescopic cylinder 260 slowly shortens to restore the horizontal plate 210, the support plate 220 and the two positioning rods 240 to a horizontal state, and the third drive motor 340 rotates in the opposite direction to enable the positioning rod 240 to drive the multiple support protrusions 250 to reset and disengage from the corner inside the rectangular welding wire 180, so that the rectangular welding wire 180 can be pushed into the rectangular groove for complete positioning.

[0071] The subsequent transportation and positioning of the end iron sheet 170, the rectangular welding wire 180 and the middle iron sheet 190 are the same and will not be described in detail.

[0072] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
