Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and in particular to a moving iron unit welding tool. Background Art

[0002] Welding equipment refers to the equipment required to implement the welding process, which can reliably join two or more components through different welding processes. This type of equipment is rich in variety and is widely used in industrial manufacturing, construction engineering, electronic component production and other fields.

[0003] For example, Chinese patent CN119681516B discloses a moving iron unit square iron welding processing equipment. This solution is achieved by opening rectangular grooves on the end faces of the end iron sheet and the middle iron sheet, filling the rectangular grooves with rectangular welding wires, and using heating to melt the welding wires, thereby connecting the end iron sheet and the middle iron sheet, thereby completing the welding of the end iron sheet and the middle iron sheet. In addition, the end iron sheet and the middle iron sheet rotate during the welding process so that they can be heated evenly, avoiding deformation of the square iron and affecting the removal of the square iron.

[0004] However, the diameter of the welding wire in the above scheme is too thin, which may cause deformation of the welding wire itself during the process of transportation, clamping, and placement, thereby affecting the coordination between the welding wire and the square iron groove, and further affecting the positioning accuracy of multiple intermediate iron sheets and end iron sheets. In addition, due to the small size and gravity of the square iron, and the unsatisfactory surface treatment of the square iron, during welding, the liquid metal after the welding wire is melted will be difficult to disperse due to surface tension, causing the square iron above it to "float" on the molten liquid metal. The gravity between the square irons alone cannot achieve consistent and close contact, resulting in tiny gaps between the square irons, which in turn causes the effect of molten metal entering the capillary groove to be less than ideal. The contact between the square irons closer to the upper side is less tight. In addition, there is contact between the guide rod and the square iron, and the friction and contact force between them will also hinder the close contact between the square irons and hinder the thermal stress deformation there. Summary of the Invention

[0005] Based on this, it is necessary to provide a moving iron unit welding tool to address the problem that the current welding wire is easily deformed, which facilitates the cooperation between the welding wire and the square iron groove and affects the uniformity of welding.

[0006] The above purpose is achieved through the following technical solutions:

[0007] A moving iron unit welding tool, comprising:

[0008] A frame, wherein a conveyor belt is provided on the frame, and a plurality of horizontal plates are placed on the conveyor belt, and square irons can be placed on the horizontal plates, wherein the square irons include two end iron plates and a plurality of middle iron plates, and rectangular grooves are formed on the upper and lower end surfaces of the plurality of middle iron plates and the end surfaces of the two end iron plates close to the plurality of middle iron plates, and the rectangular grooves can be filled with rectangular welding wires;

[0009] a welding assembly capable of heating the end iron sheets and the plurality of middle iron sheets;

[0010] A rectangular positioning plate, wherein the rectangular positioning plate is vertically slidably arranged on the horizontal plate, and push rods are respectively slidably arranged at the four corners of the positioning plate, and the push rods slide along the diagonal extension direction of the rectangular positioning plate, and the push rods are configured to position the intermediate iron sheet when installing the intermediate iron sheet, and to position the rectangular welding wire when installing the rectangular welding wire, and after the uppermost end iron sheet is installed, the push rod contacts the upper end surface of the uppermost end iron sheet and the rectangular positioning plate presses the two end iron sheets and multiple intermediate iron sheets downward;

[0011] A driving assembly is provided, wherein the driving assembly can drive the push rod to slide and can drive the rectangular positioning plate to slide vertically.

[0012] Furthermore, a rotating disk is provided on the inner circumference of the rectangular positioning plate, the axis of the rotating disk is perpendicular to the plane where the rectangular positioning plate is located, an arc-shaped through groove is provided on the end face of the rotating disk, and one end of the push rod located inside the rectangular positioning plate is slidably connected to the arc-shaped through groove, and the rotating disk rotates around its own axis to pull or push the push rod, and a screw is provided vertically and rotatably on the horizontal plate, and the screw is spirally connected to the rectangular positioning plate.

[0013] Furthermore, the drive assembly includes a drive motor, a first transmission gear and a second transmission gear. The first transmission gear is coaxial and fixedly connected to the lead screw, the second transmission gear is connected to the rotating disk by reduction transmission, and a drive wheel is coaxially and axially slidably connected to the rotating shaft of the drive motor. The drive wheel can engage with the first transmission gear or the second transmission gear.

[0014] Furthermore, the outer circumference of the rotating shaft of the driving motor is coaxially and fixedly connected with an annular electromagnet, the annular electromagnet is coaxial with the driving wheel and an elastic member is provided between the two, and the elastic member can push the driving wheel to engage with the first transmission gear.

[0015] Furthermore, two positioning rods are fixedly provided on the horizontal plate, and the two positioning rods are respectively located below the top rods on the same diagonal line of the rectangular positioning plate, and the lengths of the two positioning rods are lower than the thickness of the end iron sheets.

[0016] Furthermore, a plurality of square irons can be placed vertically on the horizontal plate, and a rectangular partition frame is provided between adjacent square irons.

[0017] Furthermore, the welding assembly includes a lifting plate and multiple heating wires. The lifting plate is vertically slidably arranged on the frame. The multiple heating wires are located on the lower end surface of the lifting plate and are surrounded. The multiple heating wires are used to heat the square iron.

[0018] Furthermore, a plurality of transverse grooves are provided on the side walls of the rectangular groove.

[0019] Furthermore, a robotic arm is provided on the conveyor belt, and the robotic arm is used to clamp the square iron.

[0020] The beneficial effects of the present invention are:

[0021] By providing a rectangular positioning plate and a push rod that slides diagonally along the plate, the present invention enables precise positioning of the intermediate iron sheet and rectangular welding wire when installing them, with the push rod abutting the inner periphery of their four corners. This not only corrects the deformation of the rectangular welding wire, ensuring a tight fit within the rectangular slot, but also ensures the precise positioning of the multiple intermediate iron sheets and end iron sheets, preventing positioning deviations from affecting the welding effect.

[0022] The present invention drives the rotation of the rotating disk and the lead screw, and can first position the middle iron sheet or rectangular welding wire through the push rod during the installation process. After the installation is completed, the rectangular positioning plate is driven downward to squeeze multiple square irons to eliminate the tiny gaps between the square irons, thereby preventing the square irons from "floating" due to surface tension of liquid metal during welding, ensuring close contact of the square irons, and improving the uniformity and reliability of welding.

[0023] The present invention uses a reducer arranged in the drive assembly, which can reduce the speed of the drive motor in multiple stages, so that the rotation speed of the rotating disk is slow, and the distance that the push rod is extended or retracted can be accurately controlled. At the same time, the annular electromagnet cooperates with the elastic part to realize the switching of the drive wheel between the drive screw and the rotating disk, ensuring that each action is carried out in an orderly manner, and further improving the accuracy of positioning and extrusion.

[0024] The present invention arranges two positioning rods on a horizontal plate, each of which is shorter than the thickness of the end iron sheet, so that the positioning rods can position the lowest end iron sheet without affecting the assembly of subsequent intermediate iron sheets. This design avoids the friction and contact force generated by the contact between the traditional guide rod and the square iron, which hinder the close contact of the square iron and thermal stress deformation, thereby further ensuring the welding quality.

[0025] By placing multiple square irons on a horizontal plate and separating them with rectangular partition frames, the present invention can weld multiple square irons at once, increasing the number of welds per session. Furthermore, a robotic arm automatically clamps and assembles the various square iron components, reducing manual labor and improving overall welding efficiency and automation.

[0050] Refer to the following Figures 1-15To describe a moving iron unit welding tool provided by the present invention, which is suitable for welding the square iron 200 in the moving iron unit, including a frame 100, and a plurality of areas are provided on the frame 100, such as an assembly area 140, a welding area 150 and a finished product area 160, the assembly area 140 is used to assemble the square iron 200, the welding area 150 is used to weld the assembled square iron 200, and the finished product area 160 is used to output the welded finished square iron 200, a conveyor belt 110 is provided on the frame 100, the conveyor belt 110 connects various areas, a plurality of horizontal plates 130 are fixedly connected to the conveyor belt 110, a connecting frame 120 is fixedly provided on the conveyor belt 110, the horizontal plates 130 are fixed to the conveyor belt 110 through the connecting frame 120, the horizontal plates 130 are used to carry the square iron 200, and the horizontal plates 130 drive the square iron 200 to move, When conveying, the conveyor belt 110 can convey the square iron 200 from the assembly area 140 to the welding area 150, and finally to the finished product area 160. Each square iron 200 in the present invention is composed of two end iron sheets 210 and multiple intermediate iron sheets 220. The two end iron sheets 210 and the multiple intermediate iron sheets 220 are all rectangular in shape, but not rectangular plates, but rectangular frames. The two end iron sheets 210 are located at the upper and lower ends of the multiple intermediate iron sheets 220. The multiple intermediate iron sheets 220 and the two end iron sheets 210 are superimposed and welded together to form the square iron 200. Rectangular grooves 240 are provided on the end faces of the multiple intermediate iron sheets 220 and the end faces of the two end iron sheets 210 close to the intermediate iron sheets 220. The shape of the rectangular grooves 240 is also rectangular frame-shaped, and the rectangular grooves 240 can accommodate rectangular welding wires 260. The frame 100 is provided with a welding assembly for heating the plurality of middle iron sheets 220 and the two end iron sheets 210 so as to melt the rectangular welding wires 260 in the rectangular grooves 240 to complete the welding of the square iron 200 .

[0051] In the prior art, when multiple intermediate iron sheets 220 and two end iron sheets 210 are stacked together, a positioning device is generally used to position the multiple intermediate iron sheets 220 and the two end iron sheets 210 for easy welding. For example, Chinese patent CN119681516B discloses a moving iron unit square iron 200 welding processing equipment, which adopts a positioning frame to position the two end iron sheets 210 and multiple intermediate iron sheets 220, and a guide rod is fixedly provided on the horizontal plate 130 to guide the assembly of the two end iron sheets 210 and the multiple intermediate iron sheets 220, and two abutting rods are used to abut on the two ends of the square iron 200. The guide rod is placed on the diagonal edges of the square iron 200, thereby achieving the positioning of the square iron 200. However, there is contact between the guide rod and the multiple intermediate iron sheets 220 and the end iron sheets 210 of the square iron 200. The friction and contact force between them will also hinder the close contact between the square irons 200 and the thermal stress deformation there. At the same time, since the diameter of the rectangular welding wire 260 is too thin, the rectangular welding wire 260 itself may be deformed during the process of transportation, clamping, and placement, thereby affecting the coordination between the rectangular welding wire 260 and the rectangular groove 240, resulting in the inaccurate positioning of the multiple intermediate iron sheets 220 and the end iron sheets 210 after heating.

[0052] Based on this, the present invention improves the positioning frame in the above scheme, and a rectangular positioning plate 300 is vertically slidably provided on the horizontal plate 130. The rectangular positioning plate 300 can move in the vertical direction, and a top rod 310 is slidably provided at the four corners of the rectangular positioning plate 300. The top rod 310 can slide simultaneously along the diagonal extension direction of the rectangular positioning plate 300. The top rod 310 is configured to be able to slide and abut against the inner periphery of the four corners of the intermediate iron sheet 220 when the intermediate iron sheet 220 is installed, thereby positioning the intermediate iron sheet 220, and to be able to slide and abut against the inner periphery of the four corners of the rectangular welding wire 260 when the rectangular welding wire 260 is installed, thereby positioning the rectangular welding wire 260, so that the rectangular welding wire 260 that is prone to deformation can be restored to a normal state, and then the rectangular welding wire 260 can fitly enter the rectangular groove 240, thereby avoiding affecting the positioning accuracy of the intermediate iron sheet 220. Moreover, as multiple intermediate iron sheets 220 are stacked, the rectangular positioning plate 300 will move upward to position each intermediate iron sheet 220 and the rectangular welding wire 260, and can also position the end iron sheet 210 located above. When the upper end iron sheet 210 is installed, the rectangular positioning plate 300 continues to move upward. When the four top rods 310 are out of contact with the inner periphery of the four corners of the upper end iron sheet 210, the top rods 310 slide outward. After the top rods 310 contact the upper end surface of the upper end iron sheet 210, the rectangular positioning plate 300 begins to move downward to squeeze the multiple intermediate iron sheets 220 and the two end iron sheets 210, thereby avoiding a decrease in the positioning accuracy of the multiple intermediate iron sheets 220 and the two end iron sheets 210 when the welding assembly is heated.

[0053] It can be understood that, through the above-mentioned rectangular positioning plate 300 that can slide vertically and multiple top rods 310 that slide diagonally along the rectangular positioning plate 300, not only multiple intermediate iron sheets 220 and two end iron sheets 210 can be positioned, but also the rectangular welding wire 260 can be positioned, thereby achieving double-stage positioning, and when the last end iron sheet 210 is installed, the rectangular positioning plate 300 can also squeeze the multiple intermediate iron sheets 220 and the two end iron sheets 210 downward, thereby preventing the positioning accuracy from being affected when the welding assembly is heated.

[0054] The cam 330 is provided with four arc-shaped slots 330 on the inner circumference of the rectangular positioning disk 320, and the axis of the rotating disk 320 is perpendicular to the plane where the rectangular positioning plate 300 is located. The end surface of the rotating disk 320 is provided with four arc-shaped slots 330. The four arc-shaped slots 330 are evenly distributed along the circumference of the rotating disk 320, and one end of each arc-shaped slot 330 is close to the center of the rotating disk 320, and the other end is close to the outer circumference of the rotating disk 320. The four push rods 310 are located at one end of the interior of the rectangular positioning plate 300 and are respectively slidably arranged in the four arc-shaped slots 330. In order to facilitate the sliding connection between the push rod 310 and the arc-shaped slots 330, a sliding rod is vertically and fixedly provided on the push rod 310, and the axis of the sliding rod is parallel to the axis of the rotating disk 320. The sliding rod is slidably arranged in the arc-shaped slot 330. When the rotating disk 320 rotates around its own axis, it can pull or push the push rod 310 to move along the extension direction of the diagonal of the rectangular positioning plate 300.

[0055] by Figure 14 As shown, when the rotating disk 320 rotates clockwise, the sliding rod will slide in the arc groove 330 to the end close to the center of the circle, thereby pushing the ejector rod 310 to move in the direction of extending out of the rectangular positioning plate 300. When the rotating disk 320 rotates counterclockwise, the sliding rod will slide in the arc groove 330 to the end close to the outer periphery of the rotating disk 320, thereby pulling the ejector rod 310 to move in the direction of retracting into the rectangular positioning plate 300.

[0056] It should be noted that in order to realize the sliding of the rectangular positioning plate 300 in the vertical direction, a screw 350 is vertically and rotatably arranged on the horizontal plate 130 in this embodiment. The axis of the screw 350 is perpendicular to the plane where the horizontal plate 130 is located. A sleeve 340 is fixedly arranged inside the rectangular positioning plate 300. The axis of the sleeve 340 is parallel to the axis of the rotating disk 320. The inner periphery of the sleeve 340 is spirally connected to the screw 350. When the screw 350 rotates around its own axis, it rotates circumferentially relative to the sleeve 340, thereby driving the rectangular positioning plate 300 to move in the vertical direction.

[0057] In a further embodiment, a driving assembly is further provided on the horizontal plate 130 of the present invention, and the driving assembly is used to drive the rotating disk 320 and the lead screw 350 to rotate around their own axis, and the driving assembly is configured to drive the rotating disk 320 to rotate clockwise when the intermediate iron sheet 220 or the rectangular welding wire 260 is located at the outer periphery of the rectangular positioning plate 300, so that the push rod 310 simultaneously pushes the inner periphery of the four corners of the intermediate iron sheet 220 or the rectangular welding wire 260 to position the intermediate iron sheet 220 or the rectangular welding wire 260. When the intermediate iron sheet 220 or the rectangular welding wire 260 is installed, the driving assembly is configured to drive the rotating disk 320 to rotate clockwise when the intermediate iron sheet 220 or the rectangular welding wire 260 is located at the outer periphery of the rectangular positioning plate 300, so that the push rod 310 simultaneously pushes the inner periphery of the four corners of the intermediate iron sheet 220 or the rectangular welding wire 260 to position the intermediate iron sheet 220 or the rectangular welding wire 260. When the other intermediate iron sheet 220 or rectangular welding wire 260 is installed, the rotating disk 320 is driven to rotate counterclockwise so that the push rod 310 is separated from the four corner inner peripheries of the intermediate iron sheet 220 or rectangular welding wire 260, and the lead screw 350 is driven to rotate to drive the rectangular positioning plate 300 to move upward for a distance to adapt to the installed intermediate iron sheet 220 or rectangular welding wire 260. During installation, since the distance between the four push rods 310 and the rectangular positioning plate 300 is short, it is convenient for the intermediate iron sheet 220 or rectangular welding wire 260 to be installed. When the top rod 310 is at the top of the uppermost end iron sheet 210, the driving assembly drives the lead screw 350 to rotate in the opposite direction to drive the rectangular positioning plate 300 to move downward. When the top rod 310 on the outer periphery of the rectangular positioning plate 300 contacts the upper end surface of the uppermost end iron sheet 210, the rectangular positioning plate 300 squeezes multiple intermediate iron sheets 220 and two end iron sheets 210 to fully position them.

[0058] Specifically, in this embodiment, the drive assembly includes a drive motor 400, a first transmission gear 410 and a second transmission gear 420. The first transmission gear 410 is coaxial and fixedly connected to the lead screw 350. The second transmission gear 420 is connected to the rotating disk 320 through a reduction transmission. A drive wheel 430 is coaxially and axially slidably connected to the rotating shaft of the drive motor 400. The drive wheel 430 can slide axially along the rotating shaft. When the drive wheel 430 slides upward along the rotating shaft, it can engage with the first transmission gear 410. The drive motor 400 drives the drive wheel 430 to rotate, and the drive wheel 430 drives the first transmission gear 410 to rotate. The first transmission gear 410 drives the lead screw 350 to rotate around its own axis, thereby enabling the rectangular positioning plate 300 to move in the vertical direction. When the driving wheel 430 slides downward along the rotating shaft, it can engage with the second transmission gear 420. The driving motor 400 drives the driving wheel 430 to rotate, and the driving wheel 430 drives the second transmission gear 420 to rotate. Since the second transmission gear 420 is connected to the rotating disk 320 through a reduction transmission, it can drive the rotating disk 320 to rotate slowly around its own axis, so that the four push rods 310 on the rotating disk 320 slowly extend or retract, and the extending or retracting distance is exactly the same.

[0059] It should be noted that in order to realize the function of enabling the driving wheel 430 to slide axially on the rotating shaft of the driving motor 400, this embodiment has an annular electromagnet 440 coaxially and fixedly connected to the outer circumference of the rotating shaft. The annular electromagnet 440 is coaxial with the driving wheel 430, and an elastic member 450 is provided between the annular electromagnet 440 and the driving wheel 430. The elastic member 450 is a compression spring. The elastic member 450 is used to push the driving wheel 430 to move upward so that the driving wheel 430 engages with the first transmission gear 410. In this embodiment, a magnet (not shown in the figure) is provided on the driving wheel 430. When the annular electromagnet 440 is energized, it can attract the magnet. The attraction force between the magnet and the annular electromagnet 440 is greater than the elastic force of the elastic member 450, so that the elastic member 450 is compressed, and the driving wheel 430 moves downward along the rotating shaft and engages with the second transmission gear 420.

[0060] It is understandable that the magnet can be omitted from the driving wheel 430. The material of the driving wheel 430 can be replaced with iron material. When the annular electromagnet 440 is energized, it can also attract the driving wheel 430 to move downward. The axial sliding setting of the driving wheel 430 and the rotating shaft in this embodiment is specifically that a limiting groove is provided on the rotating shaft, and a protrusion is provided on the inner periphery of the driving wheel 430. The protrusion moves along the limiting groove, and the protrusion limits the relative rotation of the driving wheel 430 and the rotating shaft.

[0061] Specifically, the second transmission gear 420 and the rotating disk 320 in this embodiment are connected via a speed reducer. Figure 15As shown, the reducer includes a housing 500, a second transmission gear 420 is rotatably arranged in the housing 500, and the second transmission gear 420 is partially exposed from the housing 500 to facilitate engagement with the drive wheel 430, the bottom of the second transmission gear 420 is coaxially and fixedly connected to the first small gear 510, a first large gear 540 is rotatably arranged inside the housing 500, the first large gear 540 is meshed with the first small gear 510, and the second small gear 520 is coaxially and fixedly arranged on the upper end surface of the first large gear 540, a third small gear 530 is also rotatably arranged in the housing 500, the third small gear 530 is meshed with the second small gear 520, a second large gear 550 is coaxially and fixedly arranged at the bottom of the rotating disk 320, and the second large gear 550 is coaxially and fixedly arranged. 50 is engaged with the third small gear 530 to achieve a multi-stage deceleration effect, specifically as follows: the driving wheel 430 drives the second transmission gear 420 to rotate, the second transmission gear 420 drives the first small gear 510 to rotate, the first small gear 510 drives the first large gear 540 to rotate to achieve a first-stage deceleration, the first large gear 540 drives the second small gear 520 to rotate, the second small gear 520 drives the third small gear 530 to rotate to achieve a second-stage deceleration, the third small gear 530 drives the second large gear 550 to rotate to achieve a third-stage deceleration, and finally the second large gear 550 drives the rotating disk 320 to rotate. Through multi-stage deceleration, the rotation speed of the rotating disk 320 is slowed down, which is convenient for controlling the length of the four push rods 310 extending out of the rectangular positioning plate 300.

[0062] To facilitate the connection between the second large gear 550 and the rotating disk 320 , a connecting shaft 321 is coaxially and axially slidably connected to the center of the rotating disk 320 . One end of the connecting shaft 321 is coaxially and fixedly connected to the second large gear 550 .

[0063] It should be noted that there are many types of reducers that can achieve reduction transmission connection. The reducer in the present invention is not limited to the above structure, but can also be other types of reducers that can achieve the reduction effect. No specific limitation is made here.

[0064] In a further embodiment, the present invention further provides two positioning rods 131 on the horizontal plate 130. The two positioning rods 131 are respectively located below the top rod 310 on the same diagonal line of the rectangular positioning plate 300 and are perpendicular to the horizontal plate 130. The length of the positioning rod 131 is shorter than the thickness of the end iron sheet 210, thereby preventing the two positioning rods 131 from affecting the subsequent assembly of the middle iron sheet 220. The two positioning rods 131 are used to position the lowest end iron sheet 210, so that the lowest end iron sheet 210 is positioned at the bottom of the rectangular positioning plate 300.

[0065] In a further embodiment, multiple square irons 200 can be placed on the horizontal plate 130 of the present invention. This embodiment takes three square irons 200 as an example, and each square iron 200 is separated by a rectangular partition frame 230. The shape of the rectangular partition frame 230 is the same as that of the multiple intermediate iron sheets 220 and the two end iron sheets 210, but no rectangular grooves 240 are opened on the two end faces of the rectangular partition frame 230. The installation process of the rectangular partition frame 230 is the same as that of the intermediate iron sheet 220, and it will also be positioned.

[0066] It can be understood that by placing multiple square irons 200 on each horizontal plate 130 , the number of square irons 200 welded in a single operation can be increased, thereby improving the overall welding efficiency.

[0067] Specifically, the welding assembly in the embodiment of the present invention includes a lifting plate 170 and a plurality of heating wires 180. The lifting plate 170 is vertically slidably set on the frame 100 by a hydraulic telescopic cylinder. The plurality of heating wires 180 are located on the lower end surface of the lifting plate 170. There are at least two heating wires 180 in the present invention, and the two heating wires 180 are arranged in a surrounding manner. The heating area of ​​the heating wire 180 can accommodate three square irons 200, so that the heating wire 180 can evenly heat each square iron 200. When the assembled square iron 200 is transported to the bottom of the lifting plate 170, the hydraulic telescopic cylinder is shortened to drive the lifting plate 170 to descend. The heating wire 180 on the lower end surface of the lifting plate 170 surrounds the outer periphery of the square iron 200 to evenly heat the square iron 200. The rectangular welding wire 260 inside each square iron 200 melts when it reaches the melting point, thereby welding the plurality of intermediate iron sheets 220 and the end iron sheets 210 together.

[0068] In a further embodiment, in order to further improve the connection strength between the two end iron sheets 210 and the multiple intermediate iron sheets 220, a transverse groove 250 is opened on the side wall of each rectangular groove 240, and the spacing between adjacent transverse grooves 250 is the same. The transverse groove 250 is perpendicular to the side wall of the rectangular groove 240, and the transverse groove 250 is connected to the rectangular groove 240. When the rectangular welding wire 260 in the rectangular groove 240 is heated and melted and enters the transverse groove 250, the transverse groove 250 can play a capillary role. The heated and melted welding wire liquid can be evenly distributed on the multiple intermediate iron sheets 220 or the contact surface between the end iron sheet 210 and the intermediate iron sheet 220 through the capillary action of the transverse groove 250, so that the welding wire liquid of the two end iron sheets 210 and the multiple intermediate iron sheets 220 is evenly contacted, thereby improving the connection strength between the two end iron sheets 210 and the multiple intermediate iron sheets 220.

[0069] Specifically, the frame 100 of this embodiment is also provided with multiple robotic arms 190, which are used to clamp the square iron 200, specifically for clamping the end iron sheet 210, the middle iron sheet 220, the rectangular welding wire 260 and the rectangular partition frame 230 of the square iron 200. The robotic arms 190 assemble the end iron sheet 210-rectangular welding wire 260-middle iron sheet 220-rectangular welding wire 260-middle iron sheet 220-rectangular welding wire 260 in sequence, and then assemble the rectangular partition frame 230 in the middle to separate two adjacent square irons 200.

[0070] The specific working process of a moving iron unit welding tool provided by the present invention is described in combination with the above embodiments:

[0071] Positioning assembly:

[0072] The robotic arm 190 assembles the end iron sheet 210 on the outside of the two positioning rods 131 on the horizontal plate 130, so that the lowermost end iron sheet 210 is positioned by the two positioning rods 131, and then the robotic arm 190 assembles the rectangular welding wire 260. Before the robotic arm 190 places the rectangular welding wire 260 in the rectangular groove 240, it will be pushed by the top rods 310 at the four corners of the rectangular positioning plate 300 against the inner periphery of the four corners, thereby positioning the rectangular welding wire 260 that is easily deformed. After positioning, the rectangular welding wire 260 is located directly above the rectangular groove 240, and the two have the same shape. Then the top rods 310 at the four corners of the rectangular positioning plate 300 shrink, and the rectangular welding wire 260 falls into the rectangular groove 240, and the robotic arm 190 clamps the middle iron sheet. The sheet 220 is placed on the periphery of the rectangular positioning plate 300. The rectangular positioning plate 300 moves upward a distance under the action of the driving motor 400 to position the intermediate iron sheet 220 that needs to be installed. After the rectangular positioning plate 300 stops moving, the driving motor 400 starts to drive the rotating disk 320 to rotate. The rotating disk 320 drives the four push rods 310 to extend outward at the same time, and the extended length is the same. The four push rods 310 push the inner side of the four corners of the intermediate iron sheet 220 to position the intermediate iron sheet 220. After the four push rods 310 of the rectangular positioning plate 300 retract, the rectangular top plate moves upward to position the subsequent intermediate iron sheets 220 and the rectangular welding wire 260 in turn, and the rectangular partition frame 230 between each square iron 200 is also positioned in the same way.

[0073] When the end iron sheet 210 above the third square iron 200 is positioned, the driving motor 400 drives the rotating disk 320 to rotate to retract the four push rods 310, and then drives the lead screw 350 to rotate to drive the rectangular positioning plate 300 to move upward, and then the driving motor 400 drives the rotating disk 320 in the reverse direction to extend the four push rods 310 and extend them a longer distance. The four push rods 310 are located on the upper end surfaces of the four corners of the end iron sheet 210, and then the driving motor 400 drives the lead screw 350 in the reverse direction to rotate, and the lead screw 350 drives the rectangular positioning plate 300 to move downward to squeeze the three square irons 200 so that the three square irons 200 are completely positioned.

[0074] welding:

[0075] The conveyor belt 110 conveys the assembled square iron 200 to the welding area 150. The heating wire 180 in the welding area 150 heats the square iron 200. The rectangular welding wire 260 inside the rectangular groove 240 of the square iron 200 melts to form liquid, thereby welding the end iron sheet 210 and the middle iron sheet 220 together.

[0076] Finished product transportation:

[0077] The welded square iron 200 is transported to the finished product area 160 by the conveyor belt 110. The robotic arm 190 in the finished product area 160 removes the welded square iron 200 in sequence, so that the welded square iron 200 is separated from the conveyor belt 110 and transferred to a designated location for subsequent processing.

[0078] 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.

[0079] 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.
