[0001] The invention relates to the technical field of moving iron unit square iron welding, and in particular to a moving iron unit square iron welding processing device. Background Art

[0002] Welding equipment is a special tool and machine for connecting materials. It can firmly connect two or more parts together through different welding processes. According to the application scenarios and process requirements, there are many types of welding equipment, which are widely used in industrial manufacturing, construction engineering, electronic component production and other fields.

[0003] The moving iron unit is a highly precise miniature acoustic device with a compact structure, mainly composed of magnetic, mechanical and electrical components. The square iron in the moving iron unit is a key component, which mainly plays the role of concentrating and guiding the magnetic lines of force, directly affecting the efficiency, sound performance and sensitivity of the moving iron unit. The square iron is a small metal piece with high magnetic conductivity, usually rectangular or approximately square in shape. It is located in the magnetic circuit system of the moving iron unit and usually works together with the yoke, permanent magnet and moving iron piece. In the production process of the square iron, the welding of the square iron is a key process link in the production of the moving iron unit, which directly affects the structural stability of the unit, the magnetic circuit performance and the final sound quality performance. Due to the high precision and special material properties of the square iron, its welding process needs to meet the requirements of high-strength connection, low thermal damage and high positioning accuracy.

[0043] Refer to the following Figure 1-Figure 11 To describe a moving iron unit square iron welding processing equipment provided by the present invention.

[0044] A moving iron unit square iron welding processing equipment is suitable for welding the moving iron unit square iron 200, including a frame 100, the frame 100 has an assembly area and a welding area, the assembly area is used to assemble the moving iron unit square iron 200, and the welding area is used to weld the square iron 200. A conveyor belt 110 is also provided on the frame 100, and a plurality of horizontal plates 140 are placed on the conveyor belt 110. The horizontal plates 140 are used to carry the square iron 200. When conveying, the conveyor belt 110 drives the plurality of horizontal plates 140 to move synchronously, and the horizontal plates 140 drive the square iron 200 to move. When conveying, the conveyor belt 110 can transport the square iron 200 from the assembly area to the welding area. The square iron 200 in the present invention is composed of two end iron sheets 210 and a plurality of middle iron sheets 220. Fig.10 and Fig.11As shown, the two end iron sheets 210 and the plurality of middle iron sheets 220 are all rectangular in shape, but are not rectangular plates, but are in the shape of rectangular frames. The two end iron sheets 210 are located at the upper and lower ends of the plurality of middle iron sheets 220, and the plurality of middle iron sheets 220 are located between the two end iron sheets 210, and the upper and lower end surfaces of the middle iron sheets 220 and the end surfaces of the two end iron sheets 210 close to the middle iron sheets 220 are provided with rectangular grooves 230, and rectangular welding wires 240 are arranged in the rectangular grooves 230, and the shapes of the rectangular grooves 230 and the rectangular welding wires 240 are also In a rectangular frame shape, a positioning frame 150 is rotatably arranged on the horizontal plate 140. The positioning frame 150 can position the two end iron sheets 210 and the multiple middle iron sheets 220 on the same vertical line, and the two end iron sheets 210 and the multiple middle iron sheets 220 are aligned in sequence from top to bottom through the positioning frame 150. When the two end iron sheets 210 and the multiple middle iron sheets 220 are superimposed on each other, the upper and lower rectangular grooves 230 will clamp the rectangular welding wire 240, and the rotating frame can rotate to drive the two end iron sheets 210 and the multiple middle iron sheets 220 to rotate.

[0045] The rack 100 is also provided with an assembly robot 120, which is located in the assembly area of ​​the rack 100. Figure 1 As shown, the assembly robot arm 120 can clamp two end iron sheets 210 and multiple middle iron sheets 220, and the installation sequence is to stack the two end iron sheets 210 and the middle iron sheets 220 one on top of the other, and place the rectangular welding wire 240 in the rectangular groove 230 to complete the assembly. After the assembly is completed, the conveyor belt 110 conveys the square iron 200 to the welding area for welding. The welding area is provided with a welding head 180, which is specifically located on the frame 100. The welding head 180 is used to heat the square iron 200 and rotate the positioning device 100 to heat the square iron 200. The frame 150 can make the two end iron sheets 210 and the multiple middle iron sheets 220 rotate when the welding head 180 is heated, so that the two end iron sheets 210 and the multiple middle iron sheets 220 can be heated evenly, and the rectangular welding wires 240 in the rectangular grooves 230 of the two end iron sheets 210 and the multiple middle iron sheets 220 of the square iron 200 are melted evenly, so that the two end iron sheets 210 and the multiple middle iron sheets 220 are connected together to form the square iron 200, thereby completing the welding of the two end iron sheets 210 and the multiple middle iron sheets 220.

[0046] It should be noted that when the rectangular welding wire 240 in the rectangular groove 230 is evenly heated, the overall deformation of the square iron 200 can be reduced. When the two end iron sheets 210 and the plurality of middle iron sheets 220 in the rectangular groove 230 are completely melted, they will be evenly connected.

[0047] In a further embodiment, in order to further improve the connection strength between the two end iron sheets 210 and the plurality of middle iron sheets 220, transverse grooves 231 are evenly formed on the side walls of each rectangular groove 230. Fig.10 and Fig.11 As shown, the spacing between adjacent transverse grooves 231 is the same, the transverse grooves 231 are perpendicular to the side walls of the rectangular grooves 230, and the transverse grooves 231 are connected to the rectangular grooves 230. When the rectangular welding wire 240 in the rectangular grooves 230 is heated and melted and enters the transverse grooves 231, the transverse grooves 231 can play a capillary role, and the heated and melted welding wire liquid can be evenly distributed on the contact surface between multiple intermediate iron sheets 220 or the end iron sheet 210 and the intermediate iron sheet 220 through the capillary action of the transverse grooves 231, 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.

[0048] Specifically, the frame 100 in this embodiment is provided with a lifting platform 160, which can be lifted up and down on the frame 100, and a plurality of rotating cylinders 170 are arranged on the lifting platform 160 along the conveying direction of the conveyor belt 110, such as Figure 3 As shown, the rotating cylinder 170 is vertically arranged on the lifting platform 160, that is, the axis of the rotating cylinder 170 is perpendicular to the lifting platform 160, the rotating cylinder 170 can rotate around its own axis on the lifting platform 160, and the rotating cylinder 170 can drive the positioning frame 150 to rotate, so that the welding head 180 can evenly heat the square iron 200.

[0049] It should be noted that the lifting and lowering setting of the lifting platform 160 is to adapt to the continuous welding of the square iron 200. For example, when the conveyor belt 110 transports the assembled square iron 200 to the vicinity of the lifting platform 160, the lifting platform 160 drives the rotating cylinder 170 and the welding head 180 to rise, and there is space under the lifting platform 160. At this time, the conveyor belt 110 transports the assembled square iron 200 to the bottom of the lifting platform 160, and each square iron 200 corresponds to a rotating cylinder 170 and a welding head 180. When the conveyor belt 110 stops conveying, the lifting platform 160 descends, and the lifting platform 160 drives the rotating cylinder 170 and the welding head 180 to descend, so that the welding head 180 is close to the square iron 200. When the lifting platform 160 descends to a suitable position, the welding head 180 is close to the four sides of the square iron 200, and the welding head 180 begins to heat up. At this time, the rotating cylinder 170 also drives the positioning frame 150 to rotate, so that the welding head 180 can evenly heat the square iron 200.

[0050] More specifically, in order to drive the multiple rotating cylinders 170 on the lifting platform 160 to rotate, a driving assembly is provided on the lifting platform 160, and the driving assembly can drive the multiple rotating cylinders 170 to rotate synchronously. The driving assembly includes a driving motor 300 and a synchronous belt 310. The driving motor 300 is fixedly arranged on the upper end surface of the lifting platform 160, and the synchronous belt 310 is wound around the outer circumference of the multiple rotating cylinders 170 and the outer circumference of the rotating shaft of the driving motor 300. When the driving motor 300 rotates, the multiple rotating cylinders 170 are driven to rotate synchronously through the synchronous belt 310.

[0051] It should be noted that, in order to facilitate the rotation of the rotating cylinder 170 connected to the lifting platform 160, Figure 6 and Figure 7 As shown, two bearings 171 are coaxially and fixedly connected on the outer periphery of the rotating cylinder 170. The two bearings 171 are respectively arranged near the upper and lower end surfaces of the rotating cylinder 170, and a connecting hole 161 extending in the vertical direction is opened on the lifting platform 160. The outer peripheries of the two bearings 171 are fixedly connected in the connecting hole 161, so that the rotating cylinder 170 is rotatably connected to the lifting platform 160.

[0052] It can be understood that since the rotating cylinder 170 is rotatably connected to the connecting hole 161 through two bearings 171, the rotating cylinder 170 can rotate relatively easily and does not require a large rotational force. Therefore, the middle rotating cylinders 170 in this embodiment can also be driven to rotate by the synchronous belt 310 when the contact area with the synchronous belt 310 is small.

[0053] In a further embodiment, abutment plate 172 is further provided at the bottom of the rotating cylinder 170 of the present invention, and the abutment plate 172 can abut against the square iron 200, specifically, abut against the upper end of the end iron sheet 210 above the square iron 200. The abutment plate 172 can firmly fix the square iron 200 on the positioning frame 150, and has a certain squeezing force so as to prevent the two end iron sheets 210 and multiple intermediate iron sheets 220 from deforming when being evenly heated.

[0054] It should be noted that the setting of the abutment plate 172 can also drive the square iron 200 on the positioning frame 150 to rotate. Since the positioning frame 150 is rotatably set on the horizontal plate 140, and the two end iron sheets 210 and multiple intermediate iron sheets 220 are located on the positioning frame 150, and are firmly fixed on the positioning frame 150 through the abutment of the abutment plate 172, when the rotating cylinder 170 drives the abutment plate 172 to rotate, it can also drive the two end iron sheets 210 and multiple intermediate iron sheets 220 to rotate, and at the same time drive the positioning frame 150 to rotate.

[0055] Specifically, in order to reduce the thermal stress deformation of the square iron 200, the abutment plate 172 of the present embodiment is a rectangular plate, and the size of the rectangular plate is similar to that of the square iron 200, that is, the lower end surface of the abutment plate 172 is similar in size to the two end iron sheets 210 of the square iron 200, and two abutment rods 173 are vertically arranged on the lower end surface of the abutment plate 172. The two abutment rods 173 are located at the two ends of the diagonal of the abutment plate 172, that is, on the two diagonals, so that the abutment rods 173 can abut on the diagonals of the upper end iron sheets 210 of the square iron 200. The advantage of such a setting is that space can be left for the two end iron sheets 210 and the middle iron sheet 220 to release thermal stress, thereby avoiding the thermal stress generated by the two end iron sheets 210 and multiple middle iron sheets 220 during heating from being unable to be released, thereby reducing the thermal stress of the two end iron sheets 210 and multiple middle iron sheets 220. If all the end iron sheets 210 at the upper ends of the square iron 200 are abutted, the two end iron sheets 210 and the multiple middle iron sheets 220 will not be able to release thermal stress, which will lead to irregular deformation of the two end iron sheets 210 and the multiple middle iron sheets 220, thereby affecting the welding of the two end iron sheets 210 and the multiple middle iron sheets 220, and affecting the removal of the square iron 200.

[0056] Specifically, the positioning frame 150 in this embodiment includes two guide rods 152 and a rotating block 151. The rotating block 151 is rotatably arranged at the center of the horizontal plate 140. The rotating block 151 can rotate around the central axis of the horizontal plate 140. The rotating connection method of the rotating block 151 and the horizontal plate 140 is the same as the rotating connection method of the rotating cylinder 170 and the lifting platform 160. No specific details are given here. Since the abutting rod 173 on the abutting plate 172 abuts against the end iron sheet 200 at the upper end of the square iron 200, 10, so when the rotating cylinder 170 drives the abutment plate 172 to rotate, it can also drive the assembled square iron 200 to rotate through the abutment rod 173 and the rotating block 151, and the two guide rods 152 are vertically arranged on the upper end surface of the rotating block 151, and the positions of the two guide rods 152 coincide with the two ends of the diagonal lines inside the two end iron sheets 210 and the plurality of middle iron sheets 220, that is, the guide rods 152 are located at the diagonals inside the two end iron sheets 210 and the plurality of middle iron sheets 220, as shown in detail. Fig.10 and Fig.11 As shown, the two guide rods 152 can play a guiding role in the process of assembling and stacking the two end iron sheets 210 and the multiple middle iron sheets 220, so that the two end iron sheets 210 and the multiple middle iron sheets 220 can be on the same vertical line.

[0057] It should be noted that the order of assembling the square iron 200 by the assembly robot 120 is to first install one of the two end iron sheets 210 on the rotating block 151 through two guide rods 152, and then install multiple intermediate iron sheets 220 in sequence, and install the rectangular welding wire 240 on the adjacent intermediate iron sheets 220. In this embodiment, four intermediate iron sheets 220 are taken as an example. Three assembly robot arms 120 are provided in the assembly area of ​​the frame 100. Each assembly robot arm 120 has two clamps, which can clamp two intermediate iron sheets 220 at the same time or clamp an end iron sheet 210 and an intermediate iron sheet 220 at the same time. There are six workstations on the frame 100, and every two workstations share one assembly robot arm 120. When the first horizontal plate 140 on the conveyor belt 110 moves to the first workstation, the first clamp of the first assembly robot arm 120 clamps an end iron sheet 210 and places it on the first workstation, that is, the end iron sheet 210 is located on the rotating block 151 through two guide rods 152, and the first clamp of the first assembly robot arm 120 also clamps a rectangular welding wire 240 and places it on the end iron sheet 210. The first horizontal plate 140 is moved to the second station by the conveyor belt 110, and the second clamp on the first assembly robot arm 120 clamps an intermediate iron sheet 220, that is, the first intermediate iron sheet 220 is placed on the end iron sheet 210 through two guide rods 152, and the second clamp also clamps a rectangular welding wire 240 and places it in the rectangular groove 230 of the first intermediate iron sheet 220, and so on, until the second clamp of the third assembly robot arm 120 places the second end iron sheet 210 on the intermediate iron sheet 220, the assembly of the square iron 200 is completed, and the subsequent assembly sequence on the first horizontal plate 140, the second horizontal plate 140 and the Nth (N represents a positive integer) horizontal plate 140 is the same, which will not be described in detail here. The assembled square iron 200 is transported to the welding area by the conveyor belt 110 to start welding.

[0058] Specifically, in the present embodiment, there are five welding heads 180, and the five welding heads 180 correspond to five rotating cylinders 170, so a total of five rotating cylinders 170 are arranged on the lifting platform 160, and the five rotating cylinders 170 are distributed along the conveying direction of the conveyor belt 110, so that the lifting platform 160 synchronously drives the five rotating cylinders 170 and the five welding heads 180 to move up and down, and thus five square irons 200 can be welded at one time, thereby improving the welding efficiency of the square irons 200.

[0059] In a further embodiment, a finished product area is also provided on the frame 100, and the finished product area is adjacent to the welding area. The square iron 200 welded in the welding area is transported to the finished product area through a conveyor belt 110. The finished product area is provided with a finished product robot arm 130, which can clamp the welded square iron 200 and clamp the welded square iron 200 to other designated positions, and then perform subsequent processing on the welded square iron 200.

[0060] Specifically, in this embodiment, the welding head 180 includes a plurality of heating wires 181, such as Figure 3 and Figure 4 As shown, a plurality of heating wires 181 are arranged in a surrounding manner. When the lifting platform 160 descends, the rotating cylinder 170 is driven to move downward, and the plurality of heating wires 181 arranged in a surrounding manner gradually approach the outer periphery of the square iron 200, thereby being able to heat the outer periphery of the square iron 200. Moreover, due to the rotation of the rotating cylinder 170, the square iron 200 can be driven to rotate, that is, the two end iron sheets 210 and the four middle iron sheets 220 are driven to rotate, thereby making the heating of the welding head more uniform.

[0061] It should be noted that there are two heating wires 181 in this embodiment. Figure 3 and Figure 4 As shown, the two heating wires 181 are symmetrically arranged, and can be evenly heated when the two end iron sheets 210 and the four middle iron sheets 220 rotate.

[0062] It should be noted that the distance that the conveyor belt 110 in this embodiment moves each time is fixed, that is, the distance that the conveyor belt 110 moves each time is set to be able to move a horizontal plate 140 a unit distance, and the unit distance is the distance between each assembly robot arm 120, each welding head 180, each abutment plate 172 and each finished product robot arm 130, so that the conveyor belt 110 can accurately move each horizontal plate 140 to the specified position when moving, ensuring that the square iron 200 on each horizontal plate 140 can be welded or clamped.

[0063] The specific working process of a moving iron unit square iron welding processing device provided by the present invention is described in combination with the above embodiments:

[0064] assembly:

[0065] Start the conveyor belt 110, and place the horizontal plates 140 one by one on the conveyor belt 110, and set them evenly. The interval between two horizontal plates 140 needs to be the same as the interval between two workstations. Multiple assembly robot arms 120 sequentially assemble the two end iron sheets 210 and the four middle iron sheets 220 on the rotating block 151 of the horizontal plate 140 through two guide rods 152, and install the rectangular welding wire 240 in the rectangular groove 230. After the assembly is completed, the conveyor belt 110 transports the assembled square irons 200 to the welding area in turn.

[0066] position:

[0067] The lifting platform 160 in the welding area is in an elevated state at this time. When there are five assembled square irons 200 under the lifting platform 160, the lifting platform 160 starts to descend, and the welding head 180 connected to the lower end face of the lifting platform 160 gradually approaches the square iron 200, and the two rotating abutment rods 173 on the lifting platform 160 gradually approach the end iron sheet 210 at the upper end of the square iron 200. When the two abutment rods 173 abut against the end iron sheet 210 at the upper end of the square iron 200, the lifting platform 160 stops descending, thereby completing the positioning of the square iron 200.

[0068] welding:

[0069] The driving motor 300 is started, and the driving motor 300 drives the five rotating cylinders 170 to rotate through the synchronous belt 310. The abutment plates 172 at the bottom of the five rotating cylinders 170 rotate synchronously, and the two abutment rods 173 on the abutment plates 172 drive the two end iron sheets 210 and the four middle iron sheets 220 to rotate. At the same time, the welding head 180 is started, and the heating wire 181 of the welding head 180 begins to heat. Due to the rotation of the two end iron sheets 210 and the four middle iron sheets 220, they can be heated evenly, and the rectangular welding wire 240 in the rectangular grooves 230 on the two end iron sheets 210 and the four middle iron sheets 220 is evenly melted. The liquid formed by the melting of the rectangular welding wire 240 can be evenly distributed on the end surfaces of the two end iron sheets 210 and the four middle iron sheets 220 that are in contact with each other through the capillary action of the transverse groove 231. After heating is completed, the heating is stopped, and the welding wire liquid in the rectangular groove 230 and the transverse groove 231 solidifies to complete the welding.

[0070] Finished product transportation:

[0071] After welding, the square iron 200 is transported to the finished product area through the conveyor belt 110. The finished product robot 130 in the finished product area can clamp the welded square iron 200, so that the welded square iron 200 is separated from the conveyor belt 110 and transferred to a designated location for subsequent processing.
