Description

Technical Field

[0001] This application relates to the technical field of radiator processing equipment, and in particular to a double-layer overlapping device for radiator fins. Background Art

[0002] The finned radiator is an efficient heat exchange device widely used in gas-liquid heat exchange. The finned radiator usually consists of several fins, and a single fin is mostly formed by laminating two steel plates. In the current radiator fin production line, it is usually necessary to use a manipulator to turn over a single steel plate and then laminate the two steel plates.

[0003] During the lamination process of the two steel plates, since the steel plates are usually large in size, workers are not allowed to be around the manipulator during the process of turning over the steel plates. However, during the lamination process of the upper steel plate and the lower steel plate, due to the relatively smooth surface of the steel plates, misalignment is likely to occur between the upper and lower steel plates. In order to ensure the welding quality between the two steel plates, it is usually necessary to add an artificial re-inspection process, which will increase the production steps of the radiator and thus reduce the processing efficiency of the radiator, having deficiencies. Summary of the Invention

[0004] In order to improve the processing efficiency of radiator fins, this application provides a double-layer overlapping device for radiator fins.

[0005] The double-layer overlapping device for radiator fins provided by this application adopts the following technical solutions: A double-layer overlapping device for radiator fins includes a conveying frame and a lamination seat. A lamination frame is rotatably arranged on the lamination seat. The conveying frame is located at both ends of the lamination frame. A conveying component for conveying plates is arranged on the conveying frame. A turning component for driving the lamination frame to rotate is arranged on the lamination seat. A conveying component, a positioning component, and a fixing component are arranged on the lamination frame. The conveying component is used to convey the plates from the feeding end of the lamination frame to its discharging end. The positioning component is used to fix the plates on the lamination frame. The fixing component is used to fix the two laminated plates together.

[0006] By adopting the above technical solution, the conveying component conveys the sheet on the conveying rack to the stacking rack. After the conveying component on the stacking rack conveys the first sheet to the designated position on the stacking rack, the positioning component fixes the first sheet. Then, the flipping component rotates the stacking rack by 180°. At this time, one sheet is synchronously flipped by 180°. After that, the conveying component conveys the second sheet on the conveying rack to the stacking rack. Then, the conveying component conveys the second sheet to directly above or below the first sheet. After that, the positioning component releases the positioning of the first sheet, and the two sheets are stacked together. At this time, the positioning component positions the two sheets at the same time. Then, the fixing component fixes the two sheets together, and the positioning component releases the positioning of the sheets again. Finally, the conveying component conveys the two sheets fixed together from the stacking rack to the conveying rack, thereby completing the precise fixing of the two sheets, improving the welding accuracy of the sheets in the subsequent process, and being beneficial to improving the processing efficiency of the radiator.

[0007] Optionally, the flipping component includes flipping disks arranged at both ends of the stacking rack. The flipping disks correspond to the stacking seats one by one. Feeding ports are opened on both sides of the flipping disks. Two supporting wheels are rotatably arranged on the stacking seat. The flipping disk is rotatably mounted between the two supporting wheels. A flipping motor electrically connected to the control system is arranged on one of the stacking seats. A driving gear is arranged on the output shaft of the flipping motor. A driven gear ring is coaxially arranged on the flipping disk corresponding to the flipping motor. The driving gear meshes with the driven gear ring.

[0008] By adopting the above technical solution, when the sheet enters the stacking rack through the feeding port on the flipping disk, the control system starts the flipping motor. The output shaft of the flipping motor drives the driven gear ring to rotate through the driving gear. The driven gear ring drives the stacking rack to rotate through the flipping disk, thereby achieving the effect of driving the sheet to flip by 180° by the stacking rack.

[0009] Optionally, the driven gear ring is coaxially arranged on the outer side of the flipping disk. Wear-resistant rings are coaxially arranged on both flipping disks. The wear-resistant rings are used to abut against the supporting wheels. The diameter of the wear-resistant ring is larger than the diameter of the driven gear ring.

[0010] By adopting the above technical solution, the wear-resistant ring reduces the possibility of the flipping disk being worn during long-term rotation, which is beneficial to improving the service life of the flipping disk.

[0011] Optionally, the conveying assembly includes a conveying shaft rotatably arranged on the two turnover disks. A conveying motor electrically connected to the control system is arranged on one of the turnover disks. The conveying shaft on the turnover disk where the conveying motor is located is coaxially arranged on the output shaft of the conveying motor. Sprockets are arranged on both conveying shafts, and a chain is wound around the sprockets on the two conveying shafts. A push plate is arranged on the chain, and the push plate is used to push the plate. Two side plates are symmetrically arranged on the stacking frame along the axis of the turnover disk. The side plates extend along the axis direction of the turnover disk. A plurality of intermediate shaft rods are slidably arranged on the side plates, and the intermediate shaft rods are used to support the plate. The plurality of intermediate shaft rods are arranged along the length direction of the side plates. A covering member for driving the intermediate shaft rods away from the plate is arranged on the stacking frame. The axis of the intermediate shaft rod is perpendicular to the axis of the turnover disk. A plurality of lower limit wheels are arranged on one side of the intermediate shaft rod close to the chain, and a plurality of upper limit wheels are arranged on the side of the intermediate shaft rod facing away from the chain. The intermediate shaft rods and the lower limit wheels are in one-to-one correspondence, and the intermediate shaft rods and the upper limit wheels are in one-to-one correspondence. The edge of the plate is located between the intermediate shaft rod and the lower limit wheel or between the intermediate shaft rod and the upper limit wheel.

[0012] By adopting the above technical solution, when the first plate slides onto the stacking frame, the first plate will slide between the intermediate shaft rod and the lower limit wheel, and the edge of the first plate will be placed on the intermediate shaft rod. Then the control system starts the conveying motor. The output shaft of the conveying motor rotates forward and drives the push plate on the chain to push the plate to slide on the stacking frame through the conveying shaft and the sprocket. After reaching the appropriate position, the output shaft of the conveying motor rotates reversely to reset the push plate on the chain. After that, the stacking frame drives the first plate to rotate 180°. At this time, the first plate will be placed on the lower limit wheel. Then, as the second plate slides onto the stacking frame, the second plate will slide between the intermediate shaft rod and the upper limit wheel, and at the same time, the edge of the second plate will be placed on the intermediate shaft rod. After that, the conveying motor uses the push plate on the chain to push the second plate to directly above the first plate again. Finally, the covering member drives the intermediate shaft rod to gradually separate from the edge of the plate, and the second plate will fall on the first plate under the action of gravity, so as to achieve the stacking effect of the two plates.

[0013] Optionally, the covering member includes a separating plate slidably arranged on the side plate. A plurality of intermediate shaft rods are arranged on the separating plate. A plurality of separating cylinders electrically connected to the control system are arranged on the stacking frame. The piston rods of the separating cylinders are arranged on the separating plate.

[0014] By adopting the above technical solution, the control system starts the separating cylinder. The piston rod of the separating cylinder contracts and drives the intermediate shaft rod to slide synchronously through the separating plate, so that the intermediate shaft rod gradually separates from the plate, and further the two plates are stacked together.

[0015] Optionally, the positioning member includes an end-stop cylinder disposed on the stacking rack. The end-stop cylinder is electrically connected to the control system. An end plate is disposed on the piston rod of the end-stop cylinder. The push plate is configured to press the plate against the end plate. A lateral bar is slidably disposed on the side plate. A plurality of lateral rods are disposed on the lateral bar. The plurality of lateral rods are arranged along the length direction of the side plate. The lateral rods are configured to abut against the side wall of the plate. A lateral cylinder electrically connected to the control system is disposed on the side plate. The lateral bar is disposed on the piston rod of the lateral cylinder.

[0016] By adopting the above technical solution, the control system activates the end-stop cylinder. The piston rod of the end-stop cylinder drives the end plate to slide. Then, as the push plate on the chain presses the plate against the end plate, the control system activates the lateral cylinder. The piston rod of the lateral cylinder drives the lateral bar to approach the edge of the plate. The lateral rods on the lateral bar will gradually abut against the side of the plate, thereby positioning and clamping the plate.

[0017] Optionally, the fixing member includes lifting cylinders disposed on the stacking rack and located on both sides of the stacking direction of two plates. A welding torch is disposed on the piston rod of the lifting cylinder. Both the lifting cylinder and the welding torch are electrically connected to the control system.

[0018] By adopting the above technical solution, when two plates are stacked and positioned, the control system activates the lifting cylinder and the welding torch. The piston rod of the lifting cylinder drives the welding torch to gradually approach the plates until the two plates are welded together. Finally, the piston rod of the lifting cylinder drives the welding torch to return to its original position.

[0019] Optionally, the conveying assembly includes a plurality of conveying shafts rotatably disposed on the conveying rack. Conveying rollers are coaxially disposed on the conveying shafts. The plurality of conveying shafts are arranged along the axis direction of the turning disk. Two synchronous pulleys are coaxially disposed on the conveying shafts. A synchronous belt is wound between the synchronous pulleys on adjacent two conveying shafts. A conveying motor electrically connected to the control system is disposed on the conveying rack. One of the conveying shafts is coaxially disposed on the output shaft of the conveying motor.

[0020] By adopting the above technical solution, the control system activates the conveying motor. The output shaft of the conveying motor drives one of the conveying shafts to rotate. Under the action of the synchronous pulleys and the synchronous belt, the plurality of conveying shafts rotate synchronously. Through friction, the conveying rollers convey the plate.

[0021] Optionally, a push plate is provided on the conveying rack at the feeding end of the stacking rack. A vertical plate is slidably arranged on the push plate along the axis direction of the turning plate. A push cylinder electrically connected to the control system is arranged on the push plate. The vertical plate is arranged on the piston rod of the push cylinder. A lifting plate is slidably arranged vertically on the vertical plate. A lifting cylinder electrically connected to the control system is arranged on the vertical plate. The lifting plate is arranged on the piston rod of the lifting cylinder. A push rod is arranged on the lifting plate, and the push rod is used to push the plate located at the material opening of the turning plate between the two turning plates.

[0022] By adopting the above technical solution, when the plate is conveyed to the feeding end of the stacking rack, at this time, the push plate on the chain is located below the plate and cannot play the role of pushing the plate. At this time, the control system starts the lifting cylinder and the push cylinder. The piston rod of the lifting cylinder on the vertical plate pushes the lifting plate and the push rod to rise. Then, the piston rod of the push cylinder pushes the vertical plate to slide, so that the push rod pushes the plate into the stacking rack, which is convenient for the push plate to drive the plate to slide.

[0023] Optionally, a rubber block is arranged on the push rod, and the rubber block is used to abut against the plate.

[0024] By adopting the above technical solution, the possibility of damage to the surface of the plate is reduced, which is beneficial to improving the aesthetics of the product.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The conveying component conveys the plate on the conveying rack to the stacking rack. After the conveying component on the stacking rack conveys the first plate to the designated position on the stacking rack, the positioning member fixes the first plate. Then, the turning member rotates the stacking rack by 180°. At this time, one plate is synchronously turned by 180°. Then, the conveying component conveys the second plate on the conveying rack to the stacking rack. Then, the conveying component conveys the second plate to directly above or directly below the first plate. After that, the positioning member releases the positioning effect on the first plate, and the two plates are stacked together. At this time, the positioning member simultaneously positions the two plates. Then, the fixing member fixes the two plates together. The positioning member releases the positioning of the plates again. Finally, the conveying component conveys the two plates fixed together from the stacking rack to the conveying rack, thereby completing the precise fixing of the two plates, improving the welding accuracy of the plates in the subsequent process, and being beneficial to improving the processing efficiency of the radiator; 2. When the first sheet slides onto the stacking rack, it will slide between the middle shaft rod and the lower limit wheel, and the edge of the first sheet will be placed on the middle shaft rod. Then, the control system starts the conveyor motor. The output shaft of the conveyor motor rotates forward and drives the push plate on the chain to push the sheet to slide on the stacking rack through the conveyor shaft and the sprocket. After reaching the appropriate position, the output shaft of the conveyor motor rotates reversely to reset the push plate on the chain. After that, the stacking rack drives the first sheet to rotate 180°. At this time, the first sheet will be placed on the lower limit wheel. Then, as the second sheet slides onto the stacking rack, the second sheet will slide between the middle shaft rod and the upper limit wheel, and at the same time, the edge of the second sheet will be placed on the middle shaft rod. After that, the conveyor motor uses the push plate on the chain to push the second sheet above the first sheet again. Finally, the composite part drives the middle shaft rod to gradually separate from the edge of the sheet, and the second sheet will fall on the first sheet under the action of gravity, thus achieving the stacking effect of the two sheets.

The wear-resistant rings 10 are used to abut against the supporting wheels 63. The outer diameter of the wear-resistant ring 10 is larger than the diameter of the driven gear ring 66.

[0038] Referring to Figure 1 and Figure 5 , a conveying assembly 5 for conveying the sheet 1 is arranged on the conveying frame 2. The conveying assembly 5 includes a plurality of conveying shafts 51 rotatably connected to the conveying frame 2. A conveying roller 52 is coaxially welded on the conveying shaft 51. The plurality of conveying shafts 51 are uniformly arranged along the axial direction of the turning disk 61. Two synchronous pulleys 53 are coaxially bolted on the conveying shaft 51. The two synchronous pulleys 53 are arranged along the axial direction of the conveying shaft 51.

[0041] When the control system starts the conveying motor 55, the output shaft of the conveying motor 55 drives one of the conveying shafts 51 to rotate. Due to the transmission of the synchronous pulleys 53 and the synchronous belt 54, the plurality of conveying rollers 52 on the conveying frame 2 rotate synchronously. The rotating conveying rollers 52 drive the sheet 1 to gradually approach the material inlet 62 on the turning disk 61 through friction.

[0042] Referring to Figure 2 , a conveying assembly 7 for conveying the sheet 1 from the feeding end of the stacking frame 4 to its discharging end is arranged on the stacking frame 4.

[0043] Referring toFigure 2 , Figure 3 and Figure 4 , on both of the two transmission shafts 70, sprockets 72 are welded. Multiple sprockets 72 can be arranged on the same transmission shaft 70. A chain 73 is wound around the sprockets 72 on the two transmission shafts 70. A push plate 74 is bolted to the chain 73. The push plate 74 is used to push the sheet 1. On the stacking frame 4, two side plates 75 are symmetrically arranged along the axis of the flipping disk 61. The side plates 75 extend along the axial direction of the flipping disk 61. A plurality of intermediate shaft rods 76 are slidably arranged on the side plates 75. The intermediate shaft rods 76 are used to support the edges of the sheet 1.

[0044] Refer to Figure 3 and Figure 4 , a plurality of intermediate shaft rods 76 are arranged along the length direction of the side plates 75. On the stacking frame 4, a covering member 77 for driving the intermediate shaft rods 76 away from the sheet 1 is arranged. The covering member 77 includes a separating plate 771 slidably arranged on the side plates 75. A plurality of intermediate shaft rods 76 are all welded to the separating plate 771. A plurality of separating cylinders 772 all electrically connected to the control system are bolted to the stacking frame 4. The plurality of separating cylinders 772 are evenly arranged along the length direction of the separating plate 771. The piston rods of the separating cylinders 772 are all bolted to the separating plate 771.

[0045] Refer to Figure 3 and Figure 4 , the axis of the intermediate shaft rod 76 is perpendicular to the axis of the flipping disk 61. A plurality of lower limit wheels 78 are welded to the side of the intermediate shaft rod 76 close to the chain 73. A plurality of upper limit wheels 79 are welded to the side of the intermediate shaft rod 76 facing away from the chain 73. The intermediate shaft rods 76 and the lower limit wheels 78 are in one-to-one correspondence. The intermediate shaft rods 76 and the upper limit wheels 79 are in one-to-one correspondence. The edge of the sheet 1 is located between the intermediate shaft rod 76 and the lower limit wheel 78 or between the intermediate shaft rod 76 and the upper limit wheel 79.

[0046] Refer to Figure 3 and Figure 4 , on the stacking frame 4, a positioning member 8 for fixing the sheet 1 on the stacking frame 4 is arranged. The positioning member 8 includes an end stop cylinder 81 bolted to the stacking frame 4. The end stop cylinder 81 is electrically connected to the control system. An end plate 82 is bolted to the piston rod of the end stop cylinder 81. The push plate 74 is used to press the sheet 1 against the end plate 82.

[0047] Refer to Figure 3 and Figure 4 , a lateral bar 83 is slidably arranged on the side plate 75. A plurality of lateral rods 84 are welded to the lateral bar 83. Lateral grooves 18 for the lateral rods 84 to slide are formed on the side plate 75. The plurality of lateral rods 84 are arranged along the length direction of the side plate 75. The lateral rods 84 are used to abut against the side wall of the sheet 1. A lateral cylinder 85 electrically connected to the control system is bolted to the side plate 75. The lateral bar 83 is bolted to the piston rod of the lateral cylinder 85.

[0048] Reference Figure 3 and Figure 4 On the superposition rack 4, there are fixing members 9 for fixing two superposed plates 1 together. The fixing members 9 include lifting cylinders 91 bolted to the superposition rack 4 and located on both sides of the two plates 1 in the stacking direction. A welding gun 92 is bolted to the piston rod of the lifting cylinder 91. Both the lifting cylinder 91 and the welding gun 92 are electrically connected to the control system.

[0049] Until the plate 1 slides between the middle shaft rod 76 and the lower limit wheel 78, then the control system starts the lifting cylinder 15 and the pushing cylinder 13. The piston rod of the lifting cylinder 15 pushes the lifting plate 14 and the push rod 16 to rise synchronously. Then the piston rod of the pushing cylinder 13 pushes the vertical plate 12 to slide, so that the rubber block 17 on the push rod 16 abuts against the edge of the plate 1. As the piston rod of the pushing cylinder 13 continues to push the vertical plate 12 to slide, the rubber block 17 pushes the plate 1 into the superposition rack 4 and between the two transmission shafts 70.

[0050] The control system starts the end-stop cylinder 81. After the piston rod of the end-stop cylinder 81 drives the end plate 82 to slide to the designated position, the control system starts the transmission motor 71. The output shaft of the transmission motor 71 rotates forward. The forward-rotating transmission shaft 70 drives the sprocket 72 to rotate synchronously. The sprocket 72 drives the chain 73 to rotate forward. The push plate 74 on the chain 73 pushes the plate 1 to slide on the middle shaft rod 76 until the push plate 74 presses the plate 1 against the end plate 82.

[0051] The control system starts the lateral cylinder 85. The piston rod of the lateral cylinder 85 drives the lateral bar 83 to gradually approach the edge of the plate 1. The lateral bar 83 drives the lateral rod 84 thereon to slide synchronously until the lateral rod 84 abuts against the side of the plate 1, thereby positioning the plate 1. At this time, the control system starts the transmission motor 71 to rotate in the reverse direction until the push plate 74 resets.

[0052] The control system starts the flipping motor 64. The output shaft of the flipping motor 64 drives the driven tooth ring 66 to rotate synchronously through the driving gear 65. The driven tooth ring 66 drives the superposition rack 4 to rotate synchronously through the flipping disc 61 until the superposition rack 4 drives the plate 1 to flip 180°. The control system starts the lateral cylinder 85. The piston rod of the lateral cylinder 85 drives the lateral rod 84 to disengage from the edge of the plate 771 through the lateral bar 83, and then the plate 1 will press on the lower limit wheel 78.

[0053] Then the conveying motor 55 conveys another sheet 1 to the stacking rack 4 in the same manner. At the same time, the sheet 1 is pushed between the two sprockets 72 by the push rod 16. At this time, the second sheet 1 that slides onto the stacking rack 4 is located between the intermediate shaft rod 76 and the upper limit wheel 79, and the second sheet 1 that slides in presses on the intermediate shaft rod 76. After that, the control system starts the conveying motor 71 again. The output shaft of the conveying motor 71 drives the push plate 74 on the chain 73 to push the second sheet 1 that slides in to abut against the end plate 82 again through the transmission shaft 70, the sprockets 72 and the sprockets 72.

[0054] The control system starts the separation cylinder 772. The piston rod of the separation cylinder 772 contracts and drives the intermediate shaft rod 76 to slide synchronously through the separation plate 771, so that the intermediate shaft rod 76 gradually separates from the sheet 1. The sheet 1 located above is stacked with the sheet 1 located below under the action of gravity. Then the control system starts the lateral cylinder 85 again. The piston rod of the lateral cylinder 85 drives the two sheets 1 to be abutted and positioned by the lateral rod 84 through the lateral strip 83 and the lateral rod 84.

[0055] The control system starts the lifting cylinder 91 and the electric welding gun 92. The piston rod of the lifting cylinder 91 drives the electric welding gun 92 to gradually approach the sheet 1 until the two sheets 1 are spot-welded together. Finally, the piston rod of the lifting cylinder 91 drives the electric welding gun 92 to reset. At the same time, the piston rod of the end stop cylinder 81 drives the end plate 82 to reset, and the piston rod of the lateral cylinder 85 drives the lateral strip 83 to reset.

[0056] Finally, the control system operates the conveying motor 71. The output shaft of the conveying motor 71 drives the push plate 74 on the chain 73 to push the two fixed sheets 1 to the conveying rack 2 at the discharge end of the stacking rack 4 through the transmission shaft 70, the sprockets 72 and the sprockets 72. After that, the chain 73 drives the push plate 74 to reset again. Then the sheet 1 that enters again will first be located between the intermediate shaft rod 76 and the upper limit wheel 79. After the turning disk 61 rotates reversely by 180°, the sheet 1 that slides in again will be located between the intermediate shaft rod 76 and the lower limit wheel 78, and the operation is repeated.

[0057] The implementation principle of the double-layer stacking device for radiator fins in the embodiment of the present application is as follows: The control system starts the conveying motor 55. The output shaft of the conveying motor 55 drives one of the conveying shafts 51 to rotate. Due to the transmission of the synchronous pulley 53 and the synchronous belt 54, the multiple conveying rollers 52 on the conveying rack 2 rotate synchronously. The rotating conveying rollers 52 drive the sheet 1 to gradually approach the material opening 62 on the turning disk 61 through friction.

[0058] Until the sheet 1 slides to between the intermediate shaft 76 and the lower limit wheel 78, then the control system starts the lifting cylinder 15 and the pushing cylinder 13, the piston rod of the lifting cylinder 15 pushes the lifting plate 14 and the pushing rod 16 to rise synchronously, and then the piston rod of the pushing cylinder 13 pushes the vertical plate 12 to slide, so that the rubber block 17 on the pushing rod 16 abuts against the edge of the sheet 1, as the piston rod of the pushing cylinder 13 continues to push the vertical plate 12 to slide, the rubber block 17 pushes the sheet 1 into the stacking frame 4 and is located between the two conveying shafts 70.

[0059] The control system starts the end stop cylinder 81. After the piston rod of the end stop cylinder 81 drives the end plate 82 to slide to the specified position, the control system starts the conveying motor 71. The output shaft of the conveying motor 71 rotates forward. The forward rotating conveying shaft 70 drives the sprocket 72 to rotate synchronously. The sprocket 72 drives the chain 73 to rotate forward. The push plate 74 on the chain 73 pushes the plate 1 to slide on the intermediate shaft 76 until the push plate 74 presses the plate 1 against the end plate 82.

[0060] The control system starts the lateral cylinder 85, and the piston rod of the lateral cylinder 85 drives the lateral bar 83 to gradually approach the edge of the plate 1. The lateral bar 83 drives the lateral rod 84 thereon to slide synchronously until the lateral rod 84 abuts against the side of the plate 1, thereby achieving the positioning effect on the plate 1. At this time, the control system starts the conveying motor 71 to rotate in the opposite direction until the push plate 74 is reset.

[0061] The control system starts the flip motor 64, the output shaft of the flip motor 64 drives the driven gear ring 66 to rotate synchronously through the driving gear 65, and the driven gear ring 66 drives the stacking frame 4 to rotate synchronously through the flip disk 61, until the stacking frame 4 drives the plate 1 to flip 180°, the control system starts the lateral cylinder 85, the piston rod of the lateral cylinder 85 drives the lateral rod 84 to separate from the edge of the plate 771 material 1 through the lateral bar 83, and then the plate 1 will be pressed on the lower limit wheel 78.

[0062] Then the conveying motor 55 conveys another plate 1 to the stacking frame 4 in the same way, and relies on the push rod 16 to push the plate 1 between the two sprockets 72. At this time, the second plate 1 that slides into the stacking frame 4 is located between the intermediate shaft 76 and the upper limit wheel 79, and the second plate 1 that slides in is pressed on the intermediate shaft 76. After that, the control system starts the conveying motor 71 again. The output shaft of the conveying motor 71 passes through the conveying shaft 70, the sprocket 72 and the sprocket 72, so that the push plate 74 on the chain 73 pushes the second plate 1 that slides in to abut against the end plate 82 again.

[0063] The control system activates the separation cylinder 772. The piston rod of the separation cylinder 772 contracts and drives the intermediate shaft rod 76 to slide synchronously through the separation plate 771, so that the intermediate shaft rod 76 gradually separates from the plate 771. The plate 1 located above is stacked with the plate 1 located below under the action of gravity. Then the control system activates the lateral cylinder 85 again. The piston rod of the lateral cylinder 85, through the lateral strip 83 and the lateral rod 84, makes the two plates 1 be abutted and positioned by the lateral rod 84 at the same time.

[0064] The control system activates the lifting cylinder 91 and the welding gun 92. The piston rod of the lifting cylinder 91 drives the welding gun 92 to gradually approach the plate 1 until the two plates 1 are spot-welded together. Finally, the piston rod of the lifting cylinder 91 drives the welding gun 92 to reset. At the same time, the piston rod of the end-stop cylinder 81 drives the end plate 82 to reset, and the piston rod of the lateral cylinder 85 drives the lateral strip 83 to reset.

[0065] Finally, the control system drives the conveyor motor 71. The output shaft of the conveyor motor 71, through the conveyor shaft 70, the sprocket 72 and the sprocket 72, makes the push plate 74 on the chain 73 push the two plates 1 fixed together to the conveyor rack 2 at the discharge end of the stacking rack 4. After that, the chain 73 drives the push plate 74 to reset again. Then the plate 1 that enters again will first be located between the intermediate shaft rod 76 and the upper limit wheel 79. After the flipping disc 61 rotates 180° in the reverse direction, the plate 1 that slides in again will be located between the intermediate shaft rod 76 and the lower limit wheel 78, and the operation is repeated.

[0066] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
