Description

Technical Field

[0001] This invention belongs to the field of automatic radiator assembly technology, specifically relating to an automatic assembly and welding production line for water channel plates. Background Technology

[0002] Water-channel radiators are a type of high-efficiency and energy-saving heating equipment, mainly composed of a panel, back panel, convection fins, and water pipe joints. Their core feature is a multi-channel design, which dissipates heat quickly through radiation and convection, resulting in rapid temperature rise. Generally, radiator assembly requires drilling holes in the water-channel plate and riveting bushings, followed by the installation of a T-joint assembly on the bushings. A patent with publication number CN104162771A discloses a radiator welding process, including seven welding steps: 1. Transferring the water-channel plate and drilling holes; 2. Flipping and welding the water-channel plate; 3. Manually inserting fins; 4. Multi-point welding; 5. Cutting the water-channel plate; 6. Welding the water-channel plate into a radiator; 7. Radiator processing and welding. The existing welding process has a low degree of automation; the water-channel plate and bushing loading are done manually, resulting in poor overall assembly and a high risk of errors. Furthermore, the multiple steps involved in drilling the water-channel plate and riveting the bushings contribute to low overall processing efficiency. Therefore, it is necessary to design an automated assembly and welding production line for waterway panels to overcome the above difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing an automated assembly and welding production line for water channel plates. In this invention, both the water channel plates and the positioning bushings are fed automatically. The positioning bushings are riveted simultaneously while the water channel plates are being drilled. The overall assembly efficiency is high and the connection between the water channel plates and the positioning bushings is stable and reliable.

[0004] The objective of this invention is achieved through the following technical solution: an automatic assembly and welding production line for waterway panels, comprising an adjacent main frame and a controllable conveyor line, wherein a conveying device is provided at the bottom of the main frame, and a magnetic suction component for gripping products is also provided on the main frame; the controllable conveyor lines are arranged in pairs, and a feeding platform is provided between the two controllable conveyor lines, wherein an automatic feeding component and an automatic drilling and riveting component are provided on the feeding platform; the automatic feeding component includes a push plate that can move relative to the automatic drilling and riveting component, and the automatic drilling and riveting component includes a top rod and a drill, wherein the drill and the top rod are arranged side by side and coaxially.

[0005] Preferably, the conveying device includes several transmission rollers rotatably connected to the main frame, a first motor on the side of the main frame that drives the transmission rollers to rotate when the first motor is working, and the transmission rollers are driven by a chain; the main frame is provided with pairs of limiting frames along the direction of transporting the water channel plate, and the distance between the two limiting frames is adapted to the width of the water channel plate; the end of the conveying device is provided with a controllable flow conveyor line adjacent to it, and the controllable flow conveyor line is provided with an adjustable guide wheel assembly and a clamping assembly.

[0006] Preferably, the top of the main frame is provided with a first track, on which a magnetic suction assembly is slidably mounted; the magnetic suction assembly includes a main beam frame, a mounting platform, a pair of second motors, and a pair of lifting cylinders; the main beam frame is slidably mounted on the first track, and the top of the main frame is also provided with several transmission wheels rotatably connected thereto; the transmission wheels are located on both sides of the first track, and a transmission belt is provided between the transmission wheels on both sides of the first track for connecting the two; the second motor is fixedly mounted on the main frame, and one of the transmission wheels is connected to its adjacent second motor, and the second motor drives the transmission wheel to rotate when it is working; transmission belts are provided on both sides of the main beam frame, and the transmission belts are fixedly connected to the bottom of the main beam frame.

[0007] Preferably, the top of the main beam frame is provided with a pair of lifting cylinders, and a mounting platform that can be raised and lowered relative to the main beam frame is provided directly below the main beam frame. The piston rod of the lifting cylinder is hinged to the mounting platform. A pair of first guide rods are fixedly installed on the mounting platform, and a pair of guide bushings are provided at the bottom of the main beam frame. The first guide rods pass through the guide bushings and protrude from the top of the main beam frame. A magnetic suction plate is provided at intervals on the lower end face of the mounting platform, and the magnetic suction plate is fixedly connected to the mounting platform. A pair of pushing cylinders are provided on the mounting platform, and a metal plate is provided directly below the magnetic suction plate. The piston shaft of the pushing cylinder passes through the magnetic suction plate and is fixedly connected to the metal plate. A plurality of second guide rods are provided on the metal plate, and the second guide rods pass through the mounting platform. In the default state, the metal plate and the magnetic suction plate are fitted together, and the metal plate can generate magnetic attraction at this time.

[0008] Initially, the water channel plates are stacked alternately on the side of the main frame. A magnetic suction assembly picks up individual water channel plates and transports them to a conveyor, which then moves them onto a controllable conveyor line. In the default configuration, the metal plate is attached to the magnetic suction plate, creating an attractive force. When the second motor operates, it drives a transmission wheel, which in turn drives a transmission belt, causing the main beam frame to move along the direction of the first track. The main beam frame first approaches the water channel plate, and a lifting cylinder lowers the mounting platform to pick it up. Then, the lifting cylinder raises the mounting platform, and the main beam frame transports the water channel plate between the two limiting frames. The lifting cylinder then lowers the mounting platform again, bringing the water channel plate close to the surface of the transmission roller. The lifting cylinder and the pushing cylinder work synchronously. The lifting cylinder raises the mounting platform and magnetic suction plate a certain distance; the pushing cylinder pushes the metal plate away from the magnetic suction plate, causing it to lose its magnetic attraction and allowing the water channel plate to fall precisely between the two limiting frames. Then, the first motor drives the transmission rollers to rotate. The transmission rollers are connected by a chain, which is a standard component and is not shown in the accompanying drawings. The magnetic suction assembly then repeats the above actions to grab new water channel plates, so that the water channel plates can be continuously transported onto the controllable flow conveyor line.

[0009] Preferably, the controllable conveyor line includes a main base, a drive roller, a first driven roller, a second driven roller, and a third motor. The main base is arranged side-by-side and adjacent to the main frame. The first and second driven rollers are rotatably connected to the main base. The first and second driven rollers are arranged vertically side-by-side, and the outer diameter of the first driven roller is smaller than that of the second driven roller. Several third motors are also provided on the side of the main base, and drive rollers are mounted on the motor shafts of the third motors. The drive roller is arranged between two second driven rollers, and the outer diameter of the drive roller is adapted to the outer diameter of the second driven roller. A first driven roller is also arranged side-by-side above the drive roller. The controllable conveyor lines are arranged in pairs, and a feeding platform is provided between the two controllable conveyor lines. Each main base has several clamping components for fixing the water channel plate at the end near the feeding platform. Adjustable guide roller assemblies are provided at both the front and rear ends of the main base.

[0010] Preferably, the clamping assembly includes a clamping frame, a clamping cylinder, a fixed gripper, and a movable gripper; the clamping frame is fixedly installed on the side of the main body base, and the clamping cylinder is provided inside the clamping frame; the bottom of the open end of the clamping frame is provided with a fixed gripper fixedly connected thereto, and the movable gripper is rotatably connected to the clamping frame; a connecting block is provided on the rotating shaft of the movable gripper, the piston shaft of the clamping cylinder is hinged to the connecting block, and the cylinder body of the clamping cylinder is hinged to the clamping frame; the fixed gripper and the movable gripper are arranged vertically opposite each other, and when the clamping cylinder is working, it drives the movable gripper to rotate relative to the fixed gripper; the adjustable guide wheel assembly includes a guide seat, a stroke adjustable cylinder, a lifting block, and The guide seat is fixedly installed on the side of the main base. An adjustable-stroke cylinder is installed on the top of the guide seat, and a lifting block is slidably installed inside the guide seat. The piston shaft of the adjustable-stroke cylinder is connected to the lifting block. The guide seat has a slot for mounting the lifting block, the outline of which matches the outline of the lifting block. The lifting block has a movable roller rotatably connected to it. The end of the guide seat facing the water channel plate has a strip-shaped clearance groove, the outline of which matches the outline of the movable roller's rotating shaft. The guide seat and the second driven roller are arranged adjacent to each other, and the movable roller and the second driven roller are arranged vertically side-by-side.

[0011] When the water channel plate passes through the controllable conveyor line, it first passes through the adjustable guide roller assembly and then sits between the driving roller and the first driven roller. The distance between the driving roller and the first driven roller is adapted to the edge thickness of the water channel plate, so that the third motor can transport the water channel plate when it drives the driving roller to rotate. Since the water channel plate has a certain length, the third motor and driving roller are located near both ends of the controllable conveyor line. Adjustable guide roller assemblies are located near both the driving roller and the third motor. These assemblies position the water channel plate vertically and apply pressure to its surface, resulting in greater friction and more stable and reliable movement. Several second driven rollers are located on both sides of the driving roller, reducing the number of driving rollers and the third motor, significantly lowering manufacturing costs. Each of the controllable conveyor lines is equipped with adjustable guide roller assemblies and drive rollers at both ends, allowing the water channel plate to be transported from the first controllable conveyor line to the loading platform, and then from the loading platform to the second controllable conveyor line. When the stroke-adjustable cylinder operates, it controls the lifting block to move along the direction of the slot. The lifting block is equipped with movable rollers, facilitating the adjustment of the distance between the movable rollers and the second driven rollers, thereby limiting the water channel plate between the movable rollers and the second driven rollers. Since it is necessary to drill and rivet positioning bushings at all four corners of the water channel plate, when one end of the water channel plate passes through the loading platform and is drilled, the clamping assembly near the drilling position operates to clamp and fix the water channel plate, while the third motor and the drive rollers both stop rotating. After one end of the water channel plate is drilled and riveted, the third motor and the drive roller operate, transferring the entire water channel plate to the second controllable conveyor line. When the other end of the water channel plate aligns with the loading platform, the clamping assembly on the second controllable conveyor line clamps and fixes the water channel plate. After the four corners of the water channel plate are drilled and riveted, the third motor and the drive roller operate, thus transporting the water channel plate to the subsequent production line. Here, the clamping cylinder operates, driving the connecting block to rotate, allowing the movable gripper to rotate relative to the fixed gripper, thereby facilitating the fixing or loosening of the water channel plate.

[0012] Preferably, the feeding platforms are symmetrically distributed on both sides of the controllable conveyor line. Each feeding platform is equipped with an automatic feeding component and an automatic drilling and riveting component. Several clamping components for fixing the water channel plate are provided on both sides of the feeding platform. One of the feeding platforms is equipped with a first sensor, which is located near the drill. One of the controllable conveyor lines is equipped with a second sensor, which is located near the discharge direction of the feeding platform. The first sensor is electrically connected to the clamping component in the feeding direction, and the second sensor is electrically connected to the clamping component in the discharge direction.

[0013] Preferably, the sequential automatic feeding assembly includes a vibrating feeding plate, a pusher block, and a first cylinder. The vibrating feeding plate contains several positioning bushings for riveting the water channel plates. A temporary storage seat is fixedly installed on the feeding platform, and a feeding track connects the temporary storage seat and the vibrating feeding plate. The temporary storage seat has a feeding groove communicating with the feeding track, and a feeding hole is located at the end of the feeding groove. A feeding cylinder is provided on the feeding platform, positioned below the temporary storage seat, and its piston shaft is located within the feeding hole. A pusher plate that can slide relative to the feeding platform is also provided on the feeding platform, with the pushing direction of the pusher plate perpendicular to the axial direction of the feeding groove. The platform is equipped with a second track and a first cylinder. A push block is slidably mounted on the second track, and a push plate is fixedly mounted on the push block. The second track is perpendicular to the feed chute, and the piston shaft of the first cylinder is connected to the push block. The end of the push plate is provided with a discharge hole for placing a positioning bushing. The inner wall of the discharge hole is provided with several inner recesses, and a magnet for magnetically attracting the positioning bushing is provided in the inner recesses. The outer contour of the magnet is adapted to the outer contour of the inner recesses, and the thickness of the magnet is greater than the axial length of the positioning bushing. A vibrating loading plate is provided on one side of the push plate, and an automatic drilling and riveting assembly is provided on the other side of the push plate. The automatic drilling and riveting assembly is located near the water channel plate on the controllable flow conveyor line.

[0014] Preferably, the automatic drilling and riveting assembly includes a limiting plate, a push rod, a second cylinder, a third cylinder, and a punch; the limiting plate is positioned above the controllable conveyor line and adjacent to the water channel plate on the controllable conveyor line; the feeding platform is equipped with a second cylinder and a third cylinder near the extension of the push plate, the second cylinder being positioned above the third cylinder and coaxially aligned with it; a punch is mounted on the piston shaft of the second cylinder, and a push rod is mounted on the piston shaft of the third cylinder; the punch and the push rod are positioned vertically opposite each other, and when the push plate is extended to its position by the first cylinder, the punch is coaxially aligned with the discharge hole on the push plate.

[0015] Preferably, the feeding platform is equipped with a first sensor, which is aligned with the punch; the feeding platform is positioned below the push plate and is equipped with a punch support base, through which the push rod extends to the material discharge hole on the push plate; the top of the push rod is provided with a circular protrusion for placing a positioning sleeve; the main body of the punch is cylindrical, and the end of the punch is conical; the positioning sleeve is hollow, and the outer diameter of the main body of the punch is larger than the inner diameter of the positioning sleeve; by default, a gap is left between the lower end face of the water channel plate and the upper end face of the push plate.

[0016] Since the four corners of the water channel plate need to be drilled and riveted, one end of the water channel plate is first transported to the loading platform via the first controllable conveyor line. Since the first sensor and the punch are aligned with each other, when the edge of the water channel plate that needs to be drilled passes the first sensor, the first sensor sends an electrical signal to the control panel on the production line. The control panel then sends working instructions to the clamping assembly and the automatic loading assembly in sequence. The control panel is not shown in the attached drawings of the specification. The water channel plate is fixed by the clamping assembly, so that the punch and the position of the water channel plate that needs to be drilled are aligned. In the default initial state, the push plate is in a waiting-for-feed state, with the discharge hole on the push plate aligned with the feeding hole on the temporary storage seat. At this time, the piston shaft of the feeding cylinder is pressing against the foremost positioning sleeve, blocking the remaining positioning sleeves which are then arranged side-by-side in the feed chute. After the water channel plate is fixed, the piston shaft of the feeding cylinder extends, pushing the foremost positioning sleeve into the discharge hole. Since the discharge hole contains several magnets, the positioning sleeves are attracted to it. Then, the feeding cylinder retracts and resets, releasing the remaining positioning sleeves. As the vibrating feeding tray continues to feed, new positioning sleeves are pushed into the feeding hole, ready for the next feeding. Now that the foremost positioning sleeve is in the discharge hole, the first cylinder operates, pushing the push plate and push block closer to the punch.

[0017] When the first cylinder extends to its full position, the positioning sleeve in the discharge hole aligns with the punch. Then, the third cylinder controls the push rod to extend, thus pushing the positioning sleeve out of the discharge hole. At this point, the push rod is fully extended, placing the positioning sleeve directly below the channel plate. The upper surface of the positioning sleeve is in contact with the lower surface of the channel plate, with a gap between the lower surface of the channel plate and the upper surface of the push plate. The positioning sleeve is made of metal, and its hardness is greater than that of the channel plate. A circular protrusion on the push rod positions the positioning sleeve, improving concentricity between the positioning sleeve, the punch, and the push rod, resulting in better punching and riveting. Then, the second cylinder controls the punch to press down through the channel plate, with the end of the punch extending towards the hole in the positioning sleeve. When the punch extends to its full position, a gap remains between the conical end of the punch and the upper surface of the circular protrusion. Because the end of the punch is conical, and the positioning sleeve is hollow, with the outer diameter of the punch body larger than the inner diameter of the positioning sleeve, the punch first drills a hole in the water channel plate. During the drilling process, the flange on the water channel plate conforms to the inner wall of the through hole in the positioning sleeve. After drilling, the punch continues to press down a short distance, causing the conical surface at the end of the punch to further compress the flange, thus firmly riveting the positioning sleeve to the hole in the water channel plate. After drilling and riveting, the push rod and punch automatically reset, and then the push plate automatically resets, ready to drill and rivet the other end of the water channel plate. Then, the active roller on the first controllable conveyor line transports the water channel plate to the second controllable conveyor line; when the front end of the water channel plate coincides with the second sensor, the second sensor sends an electrical signal to the control panel, and the control panel sends a working command to the clamping assembly on the second controllable conveyor line to fix the water channel plate; then the automatic feeding assembly and the automatic drilling and riveting assembly repeat the above steps in sequence to drill and rivet the other end of the water channel plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a conveying device and a magnetic suction component, the water channel plate can be continuously transported sequentially to the controllable flow conveyor line; by setting up a limiting frame, it is ensured that the water channel plate can be conveyed by the active roller and the first driven roller after entering the controllable flow conveyor line; 2. By using a pair of controllable flow conveyors, it is convenient to drill and rivet the four corners of the water channel plate, which greatly improves processing efficiency and shortens the length of the production line; 3. Drilling and riveting are both set on the loading platform, which improves processing efficiency and provides better concentricity, avoiding multiple movements of the water channel plate. 4. The adjustable guide wheel assembly, active roller, and third motor work together to facilitate the control of the waterway plate's movement; 5. The waterway plate is fixed by the clamping assembly, making the waterway plate more stable during drilling and ensuring precise drilling and riveting positions; 6. The clamping assembly, first sensor, and second sensor work together to facilitate the fixing of the waterway plate by clamping assemblies located adjacent to it, resulting in better positioning when drilling and riveting at different positions on the waterway plate; 7. The automatic feeding assembly and automatic drilling and riveting assembly work together to complete the sequential feeding of positioning bushings, while the positioning bushings are firmly riveted to the waterway plate.

A pusher block 63 is slidably mounted on the first cylinder 64 and the second track 610, and a pusher plate 61 is fixedly mounted on the pusher block 63. The second track 610 is perpendicular to the feed trough 67, and the piston shaft of the first cylinder 64 is connected to the pusher block 63. The end of the pusher plate 61 is provided with a discharge hole 611 for placing the positioning bushing 13. The inner wall of the discharge hole 611 is provided with several inner sinkers 612. The inner sinkers 612 are provided with magnets 613 for magnetically attracting the positioning bushing 13. The outer contour of the magnet 613 is adapted to the outer contour of the inner sinker 612, and the thickness of the magnet 613 is greater than the axial length of the positioning bushing 13. A vibrating loading plate 62 is provided on one side of the pusher plate 61, and an automatic drilling and riveting assembly 7 is provided on the other side of the pusher plate 61. The automatic drilling and riveting assembly 7 is located near the water channel plate on the controllable flow conveyor line 2.The automatic drilling and riveting assembly 7 includes a limiting plate 73, a push rod 71, a second cylinder 74, a third cylinder 75, and a punch 72. The limiting plate 73 is positioned above the controllable flow conveyor line 2 and is adjacent to the water channel plate on the controllable flow conveyor line 2. The feeding platform 5 is equipped with a second cylinder 74 and a third cylinder 75 near the extension of the push plate 61. The second cylinder 74 is positioned above the third cylinder 75 and the second cylinder 74 and the third cylinder 75 are coaxially aligned. The punch 72 is mounted on the piston shaft of the second cylinder 74, and the push rod 71 is mounted on the piston shaft of the third cylinder 75. The punch 72 and the push rod 71 are arranged vertically opposite each other. When the push plate 61 is extended to the position controlled by the first cylinder 64, the punch 72 is coaxially aligned with the discharge hole 611 on the push plate 61. The feeding platform 5 is equipped with a first sensor 11, which is aligned with the punch 72. The feeding platform 5 is located below the push plate 61 and is equipped with a punch support 76. The top rod 71 extends from the punch support 76 and extends toward the discharge hole 611 on the push plate 61. The top of the top rod 71 is equipped with a circular protrusion 77 for placing the positioning sleeve 13. The main body of the punch 72 is cylindrical, and the end of the punch 72 is conical. The positioning sleeve 13 is hollow, and the outer diameter of the main body of the punch 72 is larger than the inner diameter of the positioning sleeve 13. In the default state, there is a gap between the lower end face of the water channel plate and the upper end face of the push plate 61.

[0024] The specific operation process of this embodiment is as follows: In the initial state, the water channel plates are stacked at intervals on the side of the main frame 1. The magnetic suction component 4 can pick up and transport a single water channel plate to the conveying device 3, and then transport it to the controllable flow conveyor line 2 through the conveying device 3. In the default state, the metal plate 410 is attached to the magnetic suction plate 49, so the metal plate 410 will generate a suction force. When the second motor 43 works, it drives the transmission wheel 45 to rotate. The rotation of the transmission wheel 45 drives the transmission belt 46 to rotate, so the main beam frame 41 can move along the direction of the first track 10. The main beam frame 41 first approaches the water channel plate, and the lifting cylinder 44 controls the mounting platform 42 to descend and pick up the water channel plate. Then the lifting cylinder 44 controls the mounting platform 42 to rise, and the main beam frame 41 carries the water channel plate to the two limiting frames 33. Then the lifting cylinder 44 controls the mounting platform 42 to descend, so that the water channel plate approaches the surface of the transmission roller 31. Then, the lifting cylinder 44 and the pushing cylinder 411 work synchronously. The lifting cylinder 44 controls the installation platform 42 and the magnetic suction plate 49 to rise a certain distance; the pushing cylinder 411 pushes the metal plate 410 away from the magnetic suction plate 49, so that the metal plate 410 loses its magnetic attraction, and the water channel plate can fall accurately between the two limiting frames 33. Then, the first motor 32 drives the transmission roller 31 to rotate. The transmission rollers 31 are connected by a chain, which is an existing standard part and is not shown in the attached drawings of the specification. Then, the magnetic suction assembly 4 repeats the above actions to grab new water channel plates, so that the water channel plates can be continuously transported onto the controllable flow conveyor line 2.

[0025] When the water channel plate passes through the controllable flow conveyor line 2, it first passes through the adjustable guide roller assembly 8, and then sits between the active roller 22 and the first driven roller 23. The distance between the active roller 22 and the first driven roller 23 is adapted to the edge thickness of the water channel plate, so that the third motor 25 can transport the water channel plate when it drives the active roller 22 to rotate. Since the water channel plate has a certain length, the third motor 25 and the active roller 22 are set near both ends of the controllable flow conveyor line 2. The adjustable guide roller assembly 8 is set near both the active roller 22 and the third motor 25. The adjustable guide roller assembly 8 positions the water channel plate vertically and applies pressure to the surface of the water channel plate, so that the water channel plate has greater friction during movement, making the movement of the water channel plate more stable and reliable. Several second driven rollers 24 are set on both sides of the active roller 22, which reduces the number of active rollers 22 and the third motor 25, greatly reducing the manufacturing cost. Each of the controllable conveyor lines 2 is equipped with adjustable guide wheel assemblies 8 and drive rollers 22 at both ends, allowing the water channel plate to be transported from the first controllable conveyor line 2 to the loading platform 5, and then from the loading platform 5 to the second controllable conveyor line 2. When the stroke-adjustable cylinder 82 is working, it controls the lifting block 83 to move along the direction of the slot 85. The lifting block 83 is equipped with movable rollers 84, which facilitates adjustment of the distance between the movable rollers 84 and the second driven roller 24, thereby limiting the water channel plate between the movable rollers 84 and the second driven roller 24. Since it is necessary to drill and rivet positioning bushings 13 at all four corners of the water channel plate, when one end of the water channel plate passes through the loading platform 5 and is drilled, the clamping assembly 9 near the drilling position operates and clamps and fixes the water channel plate, while the third motor 25 and the drive roller 22 both stop rotating. After one end of the water channel plate is drilled and riveted, the third motor 25 and the drive roller 22 operate, and the entire water channel plate is transferred to the second controllable conveyor line 2. When the other end of the water channel plate is aligned with the loading platform 5, the clamping component 9 on the second controllable conveyor line 2 clamps and fixes the water channel plate. After the four corners of the water channel plate are drilled and riveted, the third motor 25 and the drive roller 22 operate, thereby transporting the water channel plate to the subsequent production line. Here, the clamping cylinder 92 operates, driving the connecting block 95 to rotate, so the movable gripper 94 can rotate relative to the fixed gripper 93, thereby facilitating the fixing or loosening of the water channel plate.

[0026] Since the four corners of the water channel plate need to be drilled and riveted, one end of the water channel plate is first transported to the loading platform 5 by the first controllable transfer conveyor line 2. Since the first sensor 11 and the punch 72 are aligned with each other, when the edge of the water channel plate that needs to be drilled passes the first sensor 11, the first sensor 11 sends an electrical signal to the control panel on the production line. The control panel will then send working instructions to the clamping assembly 9 and the automatic loading assembly 6 in sequence. The control panel is not shown in the attached drawings of the specification. The water channel plate is fixed by the clamping assembly 9, so that the punch 72 and the position of the water channel plate that needs to be drilled are aligned. In the default initial state, the push plate 61 is in a waiting state for feeding. At this time, the discharge hole 611 on the push plate 61 is aligned with the feeding hole 68 on the temporary storage seat 65. At this time, the piston shaft of the feeding cylinder 69 just presses against the foremost positioning sleeve 13, so the remaining positioning sleeves 13 will be blocked and arranged side by side in the feeding groove 67. After the water channel plate is fixed, the piston shaft of the feeding cylinder 69 extends, thereby pushing the foremost positioning sleeve 13 into the discharge hole 611. Since there are several magnets 613 in the discharge hole 611, the positioning sleeves 13 will be attracted into the discharge hole 611. Then the feeding cylinder 69 retracts and resets. At this time, the remaining positioning sleeves 13 lose their limit. As the vibrating feeding plate 62 continues to feed, the new positioning sleeves 13 will be pushed into the feeding hole 68, thus waiting for the next feeding. At this point, the foremost positioning bushing 13 is already inside the discharge hole 611. Then, the first cylinder 64 works, pushing the push plate 61 and the push block 63 closer to the punch 72.

[0027] When the first cylinder 64 extends to its position, the positioning sleeve 13 in the discharge hole 611 aligns with the punch 72. Then, the third cylinder 75 controls the push rod 71 to extend, thereby pushing the positioning sleeve 13 out of the discharge hole 611. At this time, the push rod 71 is fully extended, thus pressing the positioning sleeve 13 directly below the water channel plate. At this time, the upper end face of the positioning sleeve 13 is in contact with the lower end face of the water channel plate, and there is a gap between the lower end face of the water channel plate and the upper end face of the push plate 61. The positioning sleeve 13 is a metal part, and its hardness is greater than that of the water channel plate. By setting a circular protrusion 77 on the push rod 71, the positioning sleeve 13 is positioned, thereby achieving better concentricity between the positioning sleeve 13, the punch 72, and the push rod 71, resulting in better drilling and riveting effects. Then, the second cylinder 74 controls the punch 72 to press down through the water channel plate, and the end of the punch 72 extends towards the hole in the positioning sleeve 13; when the punch 72 extends to the end, there is a gap between the conical end of the punch 72 and the upper end face of the circular protrusion 77. Since the end of the punch 72 is conical; the positioning sleeve 13 is hollow, and the outer diameter of the main body of the punch 72 is larger than the inner diameter of the positioning sleeve 13; thus, the end of the punch 72 first punches a hole in the water channel plate, and during the punching process, the flange on the water channel plate fits against the inner wall of the through hole in the positioning sleeve 13; since the punch 72 can continue to press down a small distance after the punching is completed, the conical surface of the end of the punch 72 will continue to squeeze the flange, thus making the positioning sleeve 13 firmly riveted to the hole in the water channel plate. After the drilling and riveting are completed, the top rod 71 and the drill 72 automatically reset, and then the push plate 61 automatically resets, thus waiting for the other end of the waterway plate to be drilled and riveted. Then, the active roller 22 on the first controllable flow conveyor line 2 transports the waterway plate to the second controllable flow conveyor line 2; when the front end of the waterway plate coincides with the second sensor 12, the second sensor 12 sends an electrical signal to the control panel, and then the control panel sends a working command to the clamping assembly 9 on the second controllable flow conveyor line 2, thereby fixing the waterway plate; then the automatic feeding assembly 6 and the automatic drilling and riveting assembly 7 repeat the above steps in sequence, thereby drilling and riveting the other end of the waterway plate.
