Description

Technical Field

[0001] This application relates to the technical field of workpiece welding, and in particular to a welding device for the side seams of radiator fins. Background Art

[0002] A finned radiator is a device used for heat exchange with air. When producing radiator fins, it is necessary to weld the side seams of the fins.

[0003] The existing welding devices for the side seams of radiator fins are generally handheld welding torches. When in use, the user needs to hold the welding torch to weld the side seams of plate-shaped radiator fins. This welding method not only purely relies on the user's personal experience and skills to determine the quality of the welded product, with low reliability, but also is very time-consuming and laborious.

[0004] In view of this, there is a need to provide a welding device for the side seams of radiator fins. Summary of the Invention

[0005] In order to solve the problem that the existing welding device for the side seams of radiator fins purely relies on manual operation by the user, which is both time-consuming and laborious and has low reliability, this application provides a welding device for the side seams of radiator fins.

[0006] A welding device for the side seams of radiator fins provided by this application adopts the following technical solution: It includes a material transporting component, a welding component, and a collecting box. The material transporting component can transport the radiator fins from the starting end of the material transporting component to the ending end of the material transporting component; The welding component is arranged on the material transporting component and can weld the radiator fins passing directly below the welding component; The collecting box is arranged at the ending end of the material transporting component and can receive the radiator fins falling at this ending end.

[0007] By adopting the above technical solution, the user can place the radiator fins to be welded at the starting end of the material transporting component, and then start the material transporting component and the welding component, so that the radiator fins are first moved by the material transporting component to be directly below the welding component for welding, and then fall into the collecting box from the ending end of the material transporting component, so as to realize the automatic welding production of the radiator fins, thereby making this welding device for the side seams of radiator fins both time-saving and labor-saving and having high reliability.

[0008] Specifically, the material transporting assembly includes a mounting frame, a driving unit, and a plurality of rotating rollers. The mounting frame is arranged in a direction from close to the aggregate box to far away from the aggregate box. The plurality of rotating rollers are rotatably connected to the mounting frame at equal intervals along the length direction of the mounting frame. The rotating shafts of each rotating roller are arranged along the width direction of the mounting frame. The plane where the top of each rotating roller is located forms a transportation surface, and each rotating roller is in transmission connection with the driving unit. The driving unit can drive each rotating roller to rotate in the same direction and transport the radiator fins along the transportation surface.

[0009] By adopting the above technical solution, the user can first place the radiator fins on the transportation surface formed by the tops of the plurality of rotating rollers, and then start the driving unit to drive each rotating roller to rotate in the same direction, so as to transport the radiator fins along the transportation surface.

[0010] Furthermore, the driving unit includes a driving motor, a driving wheel, and a transmission ring. The driving wheel is arranged on the output shaft of the driving motor. The transmission ring is sleeved on the rotating shafts of each rotating roller and the driving wheel, and each rotating roller is in transmission connection with the driving wheel.

[0011] By adopting the above technical solution, the driving wheel of the driving motor can be in transmission connection with each rotating roller through the transmission ring, and then drive each rotating roller to rotate in the same direction.

[0012] Furthermore, the welding assembly includes a side welding unit and an end welding unit. The radiator fins include side seams and end seams. The side seams extend along the length direction of the mounting frame, and the end seams extend along the width direction of the mounting frame; The side welding unit can weld the side seams of the radiator fins passing directly below the side welding unit. The end welding unit is arranged between the side welding unit and the aggregate box and can weld the end seams of the radiator fins passing directly below the end welding unit.

[0013] By adopting the above technical solution, the side welding unit can weld the side seams of the radiator fins, and the end welding unit can weld the end seams of the radiator fins.

[0014] Furthermore, the side welding unit includes a side seam welder, a central frame, a pair of side welding wheels, and a plurality of central wheels. The side seam welder is arranged on one side of the central frame. A pair of side welding wheels are arranged opposite to each other with the transportation surface as the center. Each side welding wheel is electrically connected to the side seam welder; The mounting frame includes a first sub-frame and a second sub-frame. The central frame is disposed between the first sub-frame and the second sub-frame. The second sub-frame is located directly below the end-edge welding unit. A plurality of central wheels are arranged on the central frame along the length direction of the mounting frame. The rotation axes of the central wheels are all arranged along the width direction of the mounting frame, and the tops of the wheel surfaces of the central wheels are all located in the conveying surface. The side seam welder can drive the wheel surfaces of a pair of side welding wheels to move away from or close to each other and clamp the side edge seams of the radiator fins, and the side seam welder can drive the sides of the wheel surfaces of the side welding wheels close to the conveying surface to rotate in the direction close to the aggregate box, and drive the side seam welder to move along the central frame close to the second sub-frame.

[0015] By adopting the above technical solution, after the material conveying component is started, the first sub-frame will transport the radiator fins thereon to the central wheels of the central frame. At this time, the side seam welder will first drive the wheel surfaces of a pair of side welding wheels to move close to each other and clamp one end of the side edge seam of the radiator fins, and then drive the sides of the wheel surfaces of the side welding wheels close to the conveying surface to rotate in the direction close to the aggregate box, so that the entire side edge seam passes through between the two side welding wheels and is welded by the resistance heat generated at the contact between the side welding wheels and the side edge seam due to the output current of the side seam welder; after the other end of the side edge seam of the radiator fins leaves the side welding wheels, the radiator fins will come to the second sub-frame and be continuously conveyed by the second sub-frame.

[0016] Further, the end-edge welding unit includes a slide rail frame, a lead screw, a translation motor, an end-edge seam welder, a supporting pole block, a lifting member and an end-edge welding wheel. The slide rail frame is arranged on the second sub-frame along the width direction of the mounting frame, and a horizontal rail is arranged on the slide rail frame along its own length direction. The lead screw is rotationally connected to the slide rail frame along the length direction of the slide rail frame. The translation motor is connected to one end of the lead screw. The end-edge seam welder is arranged on the horizontal rail, and a thread ring adapted to the lead screw is arranged on the housing of the end-edge seam welder and is in transmission connection with the lead screw through the thread ring. The translation motor can drive the lead screw to rotate and drive the end-edge seam welder to move along the horizontal rail; The lifting member is in transmission connection with the supporting pole block and can drive the supporting pole block to move up and down. A supporting surface and an abutting protrusion are formed on the top of the supporting pole block. The supporting surface and the wheel surface of the end-edge welding wheel are arranged up and down opposite to each other with the conveying surface as the center. The abutting protrusion can abut against one end of the radiator fins close to the end-edge seam and limit the other end of the radiator fins from continuing to approach the abutting protrusion; The end-edge welding wheel and the supporting pole block are both electrically connected to the end-edge seam welder. When the supporting surface abuts against the radiator fin directly below the end-edge welding wheel, the end-edge seam welder can drive the end-edge welding wheel away from the radiator fin, or close to the radiator fin and clamp the radiator fin between the end-edge welding wheel and the supporting pole block.

[0017] By adopting the above technical solution, when the second sub-frame transports one end of the radiator fin close to the end-edge seam towards the end-edge welding unit, the lifting member will drive the supporting pole block to rise and make the top of the abutting protrusion higher than the transport surface, and then the abutting protrusion will abut against one end of the radiator fin close to the end-edge seam and make the radiator fin stop moving, while the supporting surface will abut against the bottom of the radiator fin; then the user can first control the end-edge seam welder to drive the wheel surface of the end-edge welding wheel close to the supporting surface and clamp one end of the end-edge seam, and then control the translation motor to drive the lead screw to rotate and drive the end-edge seam welder to move along the horizontal rail towards the direction close to the other end of the end-edge seam, and then the whole end-edge seam will pass under the end-edge welding wheel and be welded by the resistance heat generated at the abutting place between the end-edge welding wheel and the end-edge seam due to the output current of the end-edge seam welder; after the welding is completed, the end-edge seam welder will control the end-edge welding wheel to rise, and the second sub-frame will continue to move the radiator fin towards the direction close to the aggregate box. If the abutting protrusion blocks the moving path of the radiator fin at this time, the user can drive the supporting pole block to descend by the lifting member and make the top of the abutting protrusion not higher than the transport surface, so that the abutting protrusion will not block the movement of the radiator fin.

[0018] Further, the lifting member includes a support frame, a lifting seat, a moving member and a horizontal cylinder. A limiting hole is vertically formed on the support frame. The supporting pole block is arranged on the top of the lifting seat. A limiting column and a sliding rod are arranged at the bottom of the lifting seat. The bottom end of the limiting column is inserted into the limiting hole and abuts against the inner wall of the limiting hole. A waist-shaped hole is formed on the moving member, and the waist-shaped hole slopes upward in the direction from close to far away from the limiting hole. One end of the sliding rod far away from the lifting seat is inserted into the waist-shaped hole and can slide along the waist-shaped hole. The cylinder body of the horizontal cylinder is arranged on the support frame, and the piston rod of the horizontal cylinder is connected to one side of the moving member and can drive the moving member to be close to or far away from the limiting hole.

[0019] By adopting the above technical solution, the horizontal cylinder can drive the moving member to be close to or far away from the limiting hole, and then make the hole wall of the waist-shaped hole abut against the sliding rod and apply a force to the sliding rod to move together with the waist-shaped hole. Since the limiting column and the limiting hole limit the movement of the lifting seat and the sliding rod in the horizontal direction, the sliding rod can only slide along the length direction of the waist-shaped hole and make the lifting seat move up and down when the moving member translates.

[0020] Further, the lifting member includes a mounting seat, a contact block, a driving piston, a driven piston, a lifting piston rod, and a compression spring. The edge side seam is located at one end of the radiator fins away from the aggregate box. The mounting seat is disposed on the second sub-frame. The mounting seat is sequentially provided with a contact block receiving groove and a pole block receiving groove along the direction from near to far from the aggregate box. The supporting pole block is inserted into the pole block receiving groove; The interior of the mounting seat is provided with a contact block receiving cavity and a pole block receiving cavity. The driving piston abuts against the cavity wall of the contact block receiving cavity and divides the contact block receiving cavity into an upper block cavity and a lower block cavity. The piston end of the lifting piston rod and the driven piston are both disposed in the pole block receiving cavity and divide the pole block receiving cavity into an upper rod cavity and a lower rod cavity. The compression spring is abutted and arranged between the piston end of the lifting piston rod and the driven piston. A communication hole leading to the lower rod cavity is opened on the bottom wall of the lower block cavity. The lower rod cavity, the lower block cavity, and the communication hole are all filled with transmission fluid; A contact block hole leading to the contact block receiving groove is opened on the top wall of the upper block cavity. The bottom end of the contact block passes through the contact block receiving groove and the contact block hole and extends into the upper block cavity and is connected to the driving piston. The radiator fins can abut against the top end of the contact block and press down the contact block when passing over the contact block. A pole block hole leading to the pole block receiving groove is opened on the top wall of the upper rod cavity. The rod end of the lifting piston rod passes through the pole block hole and is connected to the supporting pole block; When the radiator fins approach the aggregate box along the transport surface, the top of the contact protrusion is not higher than the transport surface. The radiator fins can sequentially pass over the contact protrusion and the contact block, causing the driven piston to move upward and the compression spring to contract. When the radiator fins move away from the aggregate box along the transport surface and pass over the contact block, the driving piston moves downward and drives the driven piston, the compression spring, the lifting piston rod, and the supporting pole block to move upward together, so that the contact protrusion can abut against the radiator fins.

[0021] By adopting the above technical solution, when not under pressure, the supporting pole block will sink into the pole block accommodating groove due to its own weight, causing the driven piston, the lifting piston rod and the compression spring to move downward, and driving the driving piston and the abutting block to move upward; when the second sub-frame moves the radiator fins closer to the aggregate box along the transport surface, since the top of the abutting protrusion is not higher than the transport surface, the radiator fins can first cross the abutting protrusion and then cross the abutting block. Since the abutting protrusion is under pressure and cannot move upward, the compression spring will contract at this time, and neither the supporting pole block nor the abutting protrusion will rise to prevent the radiator fins from completely passing through between the end-edge welding wheel and the supporting pole block; then the second sub-frame will move the radiator fins away from the aggregate box along the transport surface and cross the abutting block first. At this time, the driving piston moves downward and drives the driven piston, the compression spring, the lifting piston rod and the supporting pole block to move upward together, so that the top of the abutting protrusion is higher than the transport surface, so that the abutting protrusion abuts against one end of the radiator fins near the end-edge seam and stops the radiator fins from moving, so that the end-edge seam welder can weld the end-edge seam at one end of the radiator fins away from the aggregate box.

[0022] Further, the supporting pole block is detachably connected to the lifting piston rod. The end-edge seam welder is provided with a power cord, and an electric connection clip is provided at the end of the power cord. A conductive ear adapted to the electric connection clip is provided on the side wall of the supporting pole block, and the end-edge seam welder can be electrically connected to the supporting pole block via the electric connection clip and the conductive ear.

[0023] By adopting the above technical solution, the user can replace the adapted supporting pole block according to different specifications of radiator fins, and quickly electrically connect the supporting pole block to the end-edge seam welder through the electric connection clip and the conductive ear.

[0024] Further, a ball is provided at the top of the abutting block, and the ball can abut against the side of the radiator fins.

[0025] By adopting the above technical solution, the ball can reduce the friction between the side of the radiator fins and the abutting block, facilitating the radiator fins to press the abutting block into the abutting block accommodating groove when crossing the abutting block.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. It includes a material transporting component, a welding component and an aggregate box. The material transporting component can transport radiator fins from the starting end of the material transporting component to the ending end of the material transporting component. The welding component is arranged on the material transporting component and can weld the radiator fins passing right below the welding component. The aggregate box is arranged at the ending end of the material transporting component and can receive the radiator fins falling at the ending end. The user can place the radiator fins to be welded at the starting end of the material transporting component, and then start the material transporting component and the welding component, so that the radiator fins are first moved by the material transporting component to be right below the welding component for welding, and then fall into the aggregate box from the ending end of the material transporting component, so as to realize the automatic welding production of the radiator fins, making this radiator fin side seam welding device both time-saving and labor-saving, and having high reliability; 2. The lifting member includes a mounting base, a contact block, a driving piston, a driven piston, a lifting piston rod, and a compression spring. The end-edge seam is located at one end of the radiator fins away from the aggregate box. The mounting base is arranged on the second sub-frame. The mounting base is successively provided with a contact-block receiving groove and a pole-block receiving groove along the direction from near to far from the aggregate box. The supporting pole block is inserted into the pole-block receiving groove. Inside the mounting base, there are a contact-block receiving cavity and a pole-block receiving cavity. The driving piston abuts against the cavity wall of the contact-block receiving cavity and divides the contact-block receiving cavity into a block cavity and a non-block cavity up and down. The piston end of the lifting piston rod and the driven piston are both arranged in the pole-block receiving cavity and divide the pole-block receiving cavity into a rod cavity and a non-rod cavity up and down. The compression spring is abutted and arranged between the piston end of the lifting piston rod and the driven piston. A communication hole leading to the non-rod cavity is opened on the bottom wall of the non-block cavity. The non-rod cavity, the non-block cavity, and the communication hole are all filled with transmission fluid. A contact-block hole leading to the contact-block receiving groove is opened on the top wall of the block cavity. The bottom end of the contact block passes through the contact-block receiving groove and the contact-block hole and extends into the block cavity and is connected to the driving piston. The radiator fins can abut against the top end of the contact block and press down the contact block when crossing the contact block. A pole-block hole leading to the pole-block receiving groove is opened on the top wall of the rod cavity. The rod end of the lifting piston rod passes through the pole-block hole and is connected to the supporting pole block. Since under the condition of not being pressurized, the supporting pole block will sink into the pole-block receiving groove due to its own weight, and the driven piston, the lifting piston rod, and the compression spring will move downward, while the driving piston and the contact block will move upward. Therefore, when the second sub-frame moves the radiator fins along the transport surface closer to the aggregate box, since the top of the contact protrusion is not higher than the transport surface, the radiator fins can first cross the contact protrusion and then cross the contact block. Since the contact protrusion cannot move upward under pressure, the compression spring will contract at this time, and both the supporting pole block and the contact protrusion will not rise to prevent the radiator fins from completely passing through between the end-edge welding wheel and the supporting pole block. Then the second sub-frame will move the radiator fins along the transport surface away from the aggregate box and cross the contact block first. At this time, the driving piston moves downward and drives the driven piston, the compression spring, the lifting piston rod, and the supporting pole block to move upward together, and then the top of the contact protrusion is higher than the transport surface, so that the contact protrusion abuts against one end of the radiator fins close to the end-edge seam and the radiator fins stop moving, so that the end-edge seam welder can weld the end-edge seam at one end of the radiator fins away from the aggregate box.

Detailed implementation manners

[0029] The following is further described in conjunction with the Figure 1-10 drawings: Refer to Figure 1 and Figure 2, taking the radiator fin 4 to be processed as a plate-shaped cuboid, with two end-edge seams 42 and two side-edge seams 41 arranged in a rectangular pattern on the top surface of the plate-shaped cuboid, and the end-edge seam 42 extending along the width direction of the radiator fin 4, and the side-edge seam 41 extending along the length direction of the radiator fin 4 as an example, the first embodiment of the present application includes a material transporting assembly 1, a welding assembly 2, and an aggregate box 3. The material transporting assembly 1 includes a mounting frame 11, a driving unit 12, and a plurality of rotating rollers 13. The mounting frame 11 includes a first sub-frame 111, a second sub-frame 112, a third sub-frame 113, and a fourth sub-frame 114. The first sub-frame 111, the second sub-frame 112, the third sub-frame 113, and the fourth sub-frame 114 are sequentially arranged at intervals in the direction from close to far away from the aggregate box 3. A plurality of rotating rollers 13 are rotatably connected to each sub-frame at equal intervals along its own length direction. All the rotating rollers 13 are distributed in two columns in the width direction of the mounting frame 11. The rotation axes of each rotating roller 13 are arranged along the width direction of the mounting frame 11. The top surfaces of all the rotating rollers 13 form a transportation surface. Two driving units 12 are provided on each of the first sub-frame 111, the second sub-frame 112, the third sub-frame 113, and the fourth sub-frame 114. The two driving units 12 on each sub-frame correspond one by one to the two columns of rotating rollers 13 on that sub-frame. Each driving unit 12 includes a driving motor 121, a driving wheel 122, and a transmission ring 123. The driving motor 121 is provided on the sub-frame body adjacent to the corresponding column of rotating rollers 13. Each driving wheel 122 is provided on the output shaft of the corresponding driving motor 121. Each transmission ring 123 is sleeved on the rotation axes of a column of rotating rollers 13 on the corresponding sub-frame and the driving wheel 122, and enables these rotating rollers 13 to be in transmission connection with the driving wheel 122. The transmission ring 123 can be a chain. Gears or toothed rings adapted to the chain are provided on the rotation axes of the rotating rollers 13 and the wheel surfaces of the driving wheels 122, so that the driving unit 12 can drive the corresponding rotating rollers 13 to rotate in the same direction and transport the radiator fin 4 along the transportation surface. At both ends of the first sub-frame 111, both ends of the second sub-frame 112, both ends of the third sub-frame 113, and both ends of the fourth sub-frame 114, a set of abutting wheels 14 are also rotatably connected. Each set of abutting wheels is arranged in an up-and-down opposite manner with the transportation surface as the center and includes two, and can clamp the plate-shaped radiator fin 4 passing directly below the welding assembly between the two abutting wheels 14.

[0030] See Figure 3 and Figure 4, the welding assembly 2 includes a side welding unit 21, an optical sensor (not shown in the figure), a controller (not shown in the figure), and two end-edge welding units 22. The side welding unit 21 includes two side seam welders 211, a central frame 212, and a plurality of central wheels 214. The two side seam welders 211 are oppositely arranged on both sides of the central frame 212. A pair of side welding wheels 213 are provided on each side seam welder 211. The pair of side welding wheels 213 are oppositely arranged with the transportation surface as the center. Each side welding wheel 213 is electrically connected to the side seam welder 211. The central frame 212 is arranged between the first sub-frame 111 and the second sub-frame 112. The second sub-frame 112 is located directly below the end-edge welding unit 22. The plurality of central wheels 214 are arranged on the central frame 212 along the length direction of the mounting frame 11. The rotation axes of the central wheels 214 are all arranged along the width direction of the mounting frame 11, and the tops of the wheel surfaces of the central wheels 214 are all located in the transportation surface; Since the seam welder is a prior art device with equipment that can drive the welding wheel to move up and down and rotate, the side seam welder 211 can drive the wheel surfaces of a pair of side welding wheels 213 to move away from or close to each other and clamp the side seam 41 of the radiator fin 4. Moreover, the side seam welder 211 can drive the side of the wheel surface of each side welding wheel 213 close to the transportation surface to rotate in the direction close to the aggregate box 3, and drive the side seam welder 211 to move close to the second sub-frame 112 along the central frame 212.

The optical sensor can detect whether the radiator fins 4 completely move from the third sub-frame 113 through directly below this end-edge welding unit 22 to the fourth sub-frame 114. The controller is electrically connected to the optical sensor and can receive the detection result, and the controller is also electrically connected to the end-edge welding unit 22, the drive motor 121, and the lifting member 226; the aggregate box 3 is disposed at one end of the fourth sub-frame 114 away from the end-edge welding unit 22; two slide rail frames 221 are erected directly above the third sub-frame 113. The cross beams of each slide rail frame 221 extend along the width direction of the mounting frame 11. A horizontal rail and a lead screw 222 groove are provided along the length direction of each cross beam. Each lead screw 222 is rotatably connected in a corresponding lead screw 222 groove along the length direction of the lead screw 222 groove. Each translation motor 223 is connected to one end of a corresponding lead screw 222. Each end-edge seam welder 224 is disposed on a corresponding horizontal rail, and a thread ring adapted to the lead screw 222 is provided on the housing of each end-edge seam welder 224 and is sleeved on a corresponding lead screw 222 through this thread ring, so that the translation motor 223 can drive the lead screw 222 to rotate and drive the end-edge seam welder 224 to move along the horizontal rail.

[0032] See Figure 5 and Figure 6, a supporting surface 2251 and an abutting protrusion 2252 are formed on the top of the supporting pole block 225. The supporting surface 2251 and the wheel surface of the end-edge welding wheel 227 are arranged vertically opposite to each other with the transportation surface as the center. The abutting protrusion 2252 can abut against one end of the radiator fin 4 close to the end-edge seam 42 and limit the other end of the radiator fin 4 from approaching the abutting protrusion 2252 continuously; the lifting member 226 includes a support frame 2261, a lifting seat 2262, two moving members 2263 and two horizontal cylinders 2264. A limiting hole is vertically formed on the support frame 2261. The supporting pole block 225 is arranged on the top of the lifting seat 2262. A limiting post 22621 and four sliding rods 22622 are arranged at the bottom of the lifting seat 2262. The bottom end of the limiting post 22621 is inserted into the limiting hole and abuts against the inner wall of the limiting hole. The two moving members 2263 are arranged relatively with the limiting hole as the center. Two waist-shaped holes are formed on each moving member 2263. The four sliding rods 22622 correspond to the four waist-shaped holes one by one. Each waist-shaped hole slopes upward in the direction from near to far from the limiting hole. One end of each sliding rod 22622 far from the lifting seat 2262 is inserted into a corresponding waist-shaped hole and can slide along the waist-shaped hole. The cylinders of the two horizontal cylinders 2264 are relatively arranged on the support frame 2261. The piston rod of each horizontal cylinder 2264 is connected to one side of an adjacent moving member 2263 and can drive the moving member 2263 to approach or move away from the limiting hole, and then make the hole wall of the waist-shaped hole abut against the sliding rod 22622 and apply a force to the sliding rod 22622 to move together with the waist-shaped hole. Since the limiting post 22621 and the limiting hole limit the horizontal movement of the lifting seat 2262 and the sliding rod 22622, when the moving member 2263 translates, the sliding rod 22622 can only slide along the length direction of the waist-shaped hole and move the lifting seat 2262 up and down.

[0033] The working process of the first embodiment described in this application is as follows: The user can place the radiator fin 4 to be welded on the first sub-frame 111, and then start the material transportation component 1 and the welding component 2, so that the first sub-frame 111 will transport the radiator fin 4 thereon to the center wheel 214 of the center frame 212. At this time, the two side-seam welders 211 will first drive the wheel surfaces of a pair of side welding wheels 213 to approach each other and clamp one end of the two side-edge seams 41 of the radiator fin 4 close to the aggregate box 3, and then drive the side close to the transportation surface on the wheel surfaces of each side welding wheel 213 to rotate in the direction close to the aggregate box 3, and then make the two side-edge seams 41 pass through between the two side welding wheels 213 and be welded by the resistance heat generated at the abutting place between the side welding wheel 213 and the side-edge seam 41 due to the current output by the side-seam welder 211; After the other end of the side seam 41 of the radiator fin 4 leaves the side welding wheel 213, the radiator fin 4 will come to the second sub-frame 112 and be continuously conveyed by the second sub-frame 112 towards the first end-edge welding unit 22. At this time, the lifting member 226 in the end-edge welding unit 22 will drive the supporting pole block 225 to rise and make the top of the abutting protrusion 2252 higher than the transportation surface. Subsequently, the abutting protrusion 2252 will abut against one end of the radiator fin 4 close to the aggregate box 3 and make the radiator fin 4 stop moving, while the supporting surface 2251 will abut against the bottom of the radiator fin 4. Then, the user can first control the end-edge seam welder 224 to drive the wheel surface of the end-edge welding wheel 227 close to the supporting surface 2251 and clamp one end of the end-edge side seam 42, and then control the translation motor 223 to drive the lead screw 222 to rotate self and drive the end-edge seam welder 224 to move along the horizontal rail towards the direction close to the other end of the end-edge side seam 42. Subsequently, the entire end-edge side seam 42 at one end of the radiator fin 4 close to the aggregate box 3 will pass under the end-edge welding wheel 227 and be welded by the resistance heat generated at the abutting position between the end-edge welding wheel 227 and the end-edge side seam 42 due to the output current of the end-edge seam welder 224. After the welding is completed, the first end-edge seam welder 224 will control the end-edge welding wheel 227 to rise, and the lifting member 226 corresponding to the end-edge seam welder 224 will drive the corresponding supporting pole block 225 to descend and make the top of the abutting protrusion 2252 of the supporting pole block 225 not higher than the transportation surface, so that the abutting protrusion 2252 will not block the movement of the radiator fin 4. Then, the second sub-frame 112 will continue to move the radiator fin 4 towards the third sub-frame 113, and the third sub-frame 113 will continue to move the radiator fin 4 towards the fourth sub-frame 114. When the optical sensor detects that the radiator fin 4 is about to leave the third sub-frame 113, the controller will control the lifting member 226 between the third sub-frame 113 and the fourth sub-frame 114 to drive the corresponding supporting pole block 225 to descend and make the top of the abutting protrusion 2252 of the supporting pole block 225 not higher than the transportation surface. After the optical sensor detects that the radiator fin 4 has completely moved from under the end-edge welding unit 22 through the third sub-frame 113 to the fourth sub-frame 114, the controller will control the lifting member 226 between the third sub-frame 113 and the fourth sub-frame 114 to drive the corresponding supporting pole block 225 to rise and make the top of the abutting protrusion 2252 of the supporting pole block 225 higher than the transportation surface. Then, each rotating roller 13 on the fourth sub-frame 114 will rotate in the reverse direction and drive the radiator fin 4 on the fourth sub-frame 114 to move towards the third sub-frame 113, so that one end of the radiator fin 4 far from the aggregate box 3 will abut against the supporting pole block 225 between the third sub-frame 113 and the fourth sub-frame 114. After repeating the above welding operation, the end-edge side seam 42 at one end of the radiator fin 4 far from the aggregate box 3 can also be welded and processed. Finally, after the welding of the end-edge welding unit 22 between the third sub-frame 113 and the fourth sub-frame 114 is completed, the fourth sub-frame 114 transports the radiator fins 4 thereon to one end of itself close to the aggregate box 3, and makes the radiator fins 4 fall into the aggregate box 3 for collection.

[0034] See Figure 7 , Figure 8 , Figure 9 and Figure 10 , in the second embodiment, the optical sensor and the controller are not included. The lifting member 226 between the third sub-frame 113 and the fourth sub-frame 114 includes a mounting base, four abutting blocks 2265, four driving pistons 2266, four driven pistons 2267, four lifting piston rods 2268 and four compression springs 2269. The end-edge side seam 42 is located at one end of the radiator fin 4 away from the aggregate box 3. The mounting base is connected to the fourth sub-frame 114. A row of abutting block receiving grooves and a through-slot type pole block receiving groove are sequentially formed on the mounting base along the direction from near to far from the aggregate box 3. The row of abutting block receiving grooves are spaced apart and the number is four. The supporting pole block 225 is inserted into the pole block receiving groove. Four abutting block receiving cavities and four pole block receiving cavities are provided inside the mounting base. The abutting block receiving cavities correspond to the abutting blocks 2265 and the driving pistons 2266 one by one. The pole block receiving cavities correspond to the driven pistons 2267, the lifting piston rods 2268 and the compression springs 2269 one by one. Each driving piston 2266 abuts against the wall of a corresponding abutting block receiving cavity and divides the abutting block receiving cavity into an upper block cavity and a lower blockless cavity. The piston end of each lifting piston rod 2268 and each driven piston 2267 are arranged in a corresponding pole block receiving cavity and divide the pole block receiving cavity into an upper rod cavity and a lower rodless cavity. Each compression spring 2269 is abutted and arranged between the piston end of a corresponding lifting piston rod 2268 and a corresponding driven piston 2267. A communication hole leading to a corresponding rodless cavity is formed on the bottom wall of each blockless cavity. Transmission fluid is filled in each rodless cavity, blockless cavity and communication hole. The transmission fluid can be hydraulic oil.

[0035] See Figure 9 and Figure 10, a contact hole leading to the contact block receiving groove is formed in the top wall of each cavity with a block cavity. The bottom end of each contact block 2265 passes through a corresponding contact block receiving groove and a corresponding contact hole and extends into a corresponding cavity with a block and is connected to a corresponding driving piston 2266. A pole block hole leading to the pole block receiving groove is formed in the top wall of each rod cavity. The rod end of each lifting piston rod 2268 passes through a corresponding pole block hole and is inserted into a corresponding connection hole; a power cord is provided on the end edge seam welder 224 between the third sub-frame 113 and the fourth sub-frame 114. A power connection clip 2241 is provided at the end of the power cord. A conductive ear 2253 adapted to the power connection clip 2241 is provided on the side wall at one end of the supporting pole block 225 located between the third sub-frame 113 and the fourth sub-frame 114 in the pole block receiving groove, so that the user can replace the adapted supporting pole block 225 according to different specifications of the radiator fins 4, and quickly electrically connect the supporting pole block 225 with the end edge seam welder 224 through the power connection clip 2241 and the conductive ear 2253; balls are provided on the top of each contact block 2265, so that the balls can reduce the friction between the side of the radiator fin 4 and the contact block 2265, and facilitate the radiator fin 4 to press the contact block 2265 into the contact block receiving groove when passing over the contact block 2265.

[0036] The working principle of the second embodiment described in the present application is as follows: Since under the condition of not being pressed, the supporting pole block 225 will sink into the pole block receiving groove due to its own weight, and the driven pistons 2267, the lifting piston rods 2268 and the compression springs 2269 will move downward, and the driving pistons 2266 and the contact blocks 2265 will move upward; when the third sub-frame 113 moves the radiator fin 4 along the transport surface close to the aggregate box 3, since the top of the contact protrusion 2252 is not higher than the transport surface, the radiator fin 4 can first cross the contact protrusion 2252 and then cross the contact block 2265. Since the contact protrusion 2252 cannot move upward under pressure, the compression spring 2269 will contract at this time, and the supporting pole block 225 and the contact protrusion 2252 will not rise and prevent the radiator fin 4 from completely passing through between the end edge welding wheel 227 and the supporting pole block 225 to the fourth sub-frame 114; then the fourth sub-frame 114 will move the radiator fin 4 along the transport surface away from the aggregate box 3 and cross the contact block 2265 one step ahead. At this time, each driving piston 2266 moves downward and drives each driven piston 2267, the compression spring 2269, the lifting piston rod 2268 and the supporting pole block 225 to move upward together, and then the top of the contact protrusion 2252 is higher than the transport surface, so that the contact protrusion 2252 abuts against one end of the radiator fin 4 close to the end edge seam 42 and the radiator fin 4 stops moving, so that the end edge seam welder 224 can weld the end edge seam 42 at one end of the radiator fin 4 away from the aggregate box 3.

[0037] The implementation principle of a radiator fin edge welding device described in this application is as follows: The user can place the radiator fins 4 to be welded at the starting end of the material conveying component 1, and then start the material conveying component 1 and the welding component 2, so that the radiator fins 4 are first moved by the material conveying component 1 to be directly below the welding component 2 for welding, and then fall into the aggregate box 3 at the end of the material conveying component 1, so as to realize the automatic welding production of the radiator fins 4, making this radiator fin edge welding device both time-saving and labor-saving, and with high reliability.
