Description

Technical Field

[0001] This invention relates to the field of radiator assembly technology, specifically to an assembly device for cooling pipes of an automotive water tank radiator. Background Technology

[0002] The car radiator is part of the car's cooling system. In the engine's water-cooling system, the radiator consists of three parts: the inlet chamber, the outlet chamber, and the main fins and cooling pipes. Coolant flows inside the cooling pipes, while air passes outside. The hot coolant cools down by dissipating heat to the air, while the cold air warms up by absorbing the heat dissipated by the coolant. Therefore, the radiator is a heat exchanger. The car radiator helps maintain the car's components within an appropriate temperature range under all operating conditions. The car radiator is an important system for controlling the operating temperature of the car engine, and its quality directly affects the overall performance of the car engine.

[0003] When installing cooling tubes in radiators, manual insertion of each tube is required, which necessitates repeated adjustments and alignment. Fatigue significantly impacts quality. When feeding from a vibratory feeder, the sheet-like cooling tubes are prone to stacking or tipping over, requiring frequent machine shutdowns for cleaning. Traditional equipment operates with each module independently, and the timing of cylinder / motor actions needs precise calibration. Asynchrony can lead to cooling tube accumulation or omissions. Summary of the Invention

[0023] This invention provides an assembly device for cooling pipes in an automotive radiator. It offers the following advantages:

[0024] 1. This invention features a synchronous and collaborative operation system: through the mechanical coupling (traction arm, closed-loop chute) between the material tray carrying mechanism and the material feeding guide mechanism, strict synchronization between the radiator frame conveying and the cooling pipe feeding is achieved. When the frame enters the assembly position, the cooling pipe automatically begins continuous single-piece conveying; after the frame is in place, the inclined groove trigger mechanism of the guide rail self-locks, precisely cutting off the material supply with the error controlled within the mechanical tolerance range. The pipe laying and frame positioning work in parallel, improving efficiency compared to traditional step-by-step operations.

[0025] 2. This invention features adaptive gradient feeding technology: Horizontal feed tube: a large-capacity buffer area, which achieves gravity pre-sorting through an inclined guide plate; Medium-diameter feed tube: a trapezoidal cross-section shrinkage structure, which uses an inclined platform to separate stacked sheets into single rows; Small-diameter feed tube: a curved outlet design at the end, which ensures that the sheet slides into the evenly spreading mechanism at an inclination angle, avoiding attitude deviation caused by free fall, and the guide plate rotates to close the channel when the machine stops, completely eliminating the problem of excess material dripping.

[0026] 3. The present invention has a mechanical precision alignment system: the push-up inclined block of the stationary card strip and the sliding plate-shaped slide form a "scissor-like" action. Through the change of the angle between the trapezoidal bearing block and the straight limit strip, the cooling pipe is controlled to fall. The positioning groove is replicated according to the 1:1 spacing of the frame slots to ensure that the sheet falls smoothly. After the bearing pool contacts the tail baffle plate, the bidirectional positioning of the frame lifting and the even spreading mechanism is completed through pure mechanical linkage.

[0027] 4. The present invention has a fault self-protection feature: the closed-loop chute requires the feeding mechanism to be fully reset before the material tray mechanism can perform the next feeding, thus preventing misoperation. Attached Figure Description

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see the appendix Figure 1 - Appendix Figure 3This invention provides an assembly device for automotive radiator cooling pipes, including an external frame 1 and an internal frame 2 for fixing the structure of the assembly device. A guide rail 3 is located on the internal frame 2, forming a positioning pipe for controlling the start and stop of cooling pipe input. A suspended side frame 4 is located on the internal frame 2, fixing the radiator frame component's load-bearing and conveying guiding structure. The internal frame 2 is fixedly embedded inside the external frame 1. The guide rail 3 is relatively fixed to the inner wall of the internal frame 2, and a closed-loop groove is provided on the inner side of the guide rail 3. The two ends of the closed-loop groove of the guide rail 3 are provided with inclined and relatively parallel inclined groove portions. The suspended side frame 4 is relatively fixed to the inner wall of the internal frame 2. A feeding guiding mechanism 5 is... The device is automatically and in batches assembled into the automotive radiator frame by an external frame 1. The internal frame 2 serves as the carrier for the entire assembly structure. The raw material for the finned cooling tubes is input through the feeding guide mechanism 5, which moves from the top of the internal frame 2. The raw material for the radiator frame to be installed is placed on the feeding guide mechanism 7. The feeding guide mechanism 6 is fixed on the suspended side frame 4 and extends into the internal frame 2. The feeding guide mechanism 7 is located below the feeding guide mechanism 5. The feeding guide mechanism 7 is displaced inside the internal frame 2 via the feeding guide mechanism 6. The evenly spreading assembly mechanism 8 is positioned opposite the feeding guide mechanism 6. The material tray can move along the feeding guide mechanism 5 installed inside the built-in frame 2. After the material tray carrying mechanism 7 completes the loading of the radiator frame components in the built-in frame 2, it is pushed into the built-in frame 2 along the material tray guide mechanism 6. The feeding guide mechanism 5 will move synchronously along the built-in frame 2 following the movement of the material tray carrying mechanism 7, and feed the sheet-like cooling tube raw materials into the evenly spreading assembly mechanism 8 installed on the top of the material tray guide mechanism 6 in a single-piece sequential feeding manner. While the feeding guide mechanism 5 is moving, the closed-loop sliding groove of the guide rail 3 restricts and drives the feeding guide mechanism 5 to continuously feed the sheet-like cooling tubes until the material tray carrying mechanism 7, which carries the radiator frame, is completely inserted into the built-in frame 2 along the material tray guide mechanism 6. Afterwards, the closed-loop groove of the guide rail 3 will guide the feeding guide mechanism 5 to stop feeding synchronously, while the tray bearing mechanism 7 will touch the components of the evenly spreading assembly mechanism 8, driving the evenly spreading assembly mechanism 8 to operate, and guiding the sheet-like cooling tubes laid flat on the top of the evenly spreading assembly mechanism 8 to be assembled into the radiator frame in a falling manner, so as to complete the automatic assembly of the radiator cooling tubes. Then, the tray bearing mechanism 7 is pulled back, and the feeding guide mechanism 5 is driven to follow the tray bearing mechanism 7 to move on the top of the built-in frame 2 until the tray bearing mechanism 7 is completely separated from the built-in frame 2. Then, the radiator frame with the completed cooling tube assembly can be retrieved, and the feeding guide mechanism 5 will also reset along the closed-loop groove of the guide rail 3 to wait for the assembly operation of a set of frames.

[0045] Please see the appendix Figure 1 - Appendix Figure 9The feeding guide mechanism 5 is located on the built-in frame 2 and works with the closed-loop slide groove of the guide rail 3 to sequentially transport sheet-shaped cooling pipe components. The feeding guide mechanism 5 includes a horizontal material tube 51, side slides 52 distributed and fixed on both sides of the horizontal material tube 51, and a traction arm structure fixed on the outside of the side slides 52 and extending to both sides of the material tray guide mechanism 6. The horizontal material tube 51 slides on the top of the built-in frame 2 through the side slides 52 and extends into the built-in frame 2. A medium-diameter material tube 53 is fixed at the bottom of the horizontal material tube 51, and a trapezoidal protrusion structure is provided on the side intersecting with the medium-diameter material tube 53. A guide inclined plate 54 is rotatably located on the other side of the intersection of the horizontal material tube 51 and the medium-diameter material tube 53, and is located in the area of ​​the trapezoidal protrusion structure. Flat plates are fixed at both ends of the rotation shaft of the guide inclined plate 54. A guide rod 55 is arranged parallel to the intermediate diameter material tube 53. A convex shaft structure at the outer end of the parallel guide rod 55 is embedded in the closed-loop groove of the guide rail 3. A top block structure is provided on the side wall of the intermediate diameter material tube 53 to prevent the guide inclined plate 54 from extending outside the horizontal material tube 51. A top block structure is provided on the side wall of the intermediate diameter material tube 53 to prevent the guide inclined plate 54 from rotating outside the horizontal material tube 51. A small diameter material tube 56 is fixed at the bottom output port of the intermediate diameter material tube 53, and a ramp structure is provided at the intersection with the small diameter material tube 56. The bottom of the small diameter material tube 56 is inclined, and the bottom inclined opening is close to the top of the evenly spreading assembly mechanism 8. First, the horizontal material tube 51, intermediate diameter material tube 53 and small diameter material tube 56 included in the feeding guide mechanism 5 are combined to form a conveyor. The conveying pipe structure gradually flattens and shrinks. The horizontal material pipe 51 is linearly displaced on the top of the built-in frame 2 via the side slides 52. The traction arm structures on both sides of the side slides 52 are fixed to the end structure of the tray carrying mechanism 7. As the tray carrying mechanism 7 moves along the tray guide mechanism 6, it moves synchronously along the top of the built-in frame 2 using the side slides 52 installed on both sides. The sheet-like cooling tube material pre-loaded inside the horizontal material pipe 51 is gradually reduced in size by the medium-diameter material pipe 53 installed at its bottom output port. The cooling tube material carried by the horizontal material pipe 51 is guided in small batches along the inclined guide plate 54 into the medium-diameter material pipe 53. The small-diameter material pipe 56 installed at the bottom output end of the medium-diameter material pipe 53 continues to decrease in size by the space. The raw material in the medium-diameter material tube 53 continues to be guided by the inclined platform structure at the bottom and enters the small-diameter material tube 56 in a continuous single-piece falling manner. Finally, it is continuously output in a single piece and laid flat on the evenly spreading assembly mechanism 8 along the curved output port at the bottom of the small-diameter material tube 56. The two ends of the closed-loop slide groove of the guide rail 3 are parallel and inclined groove structures. After the material tray bearing mechanism 7 drives the frame material to completely enter the built-in frame 2, the convex shaft structure of the parallel guide rod 55 will also reach the end inclined groove of the closed-loop slide groove of the guide rail 3. The end inclined groove drives the convex shaft structure to move to the upper groove of the closed-loop slide groove, generating a traction force for the parallel guide rod 55 to rotate. At the same time, the parallel guide rod 55 drives the guide inclined plate 54 to rotate inside the horizontal material tube 51.The material is pressed against the trapezoidal protruding structure installed between the horizontal material pipe 51 and the medium-diameter material pipe 53. The guide plate 54 closes the conveying channel between the horizontal material pipe 51 and the medium-diameter material pipe 53, thereby simultaneously stopping the feeding guide mechanism 5 from conveying the flat-laid sheet-like cooling pipes to the top of the evenly spreading assembly mechanism 8.

[0046] Please see the appendix Figure 1 - Appendix Figure 12 The tray guiding mechanism 6 is located on the suspended side frame 4 and is used to form a radiator frame component carrying and conveying guiding structure. The tray guiding mechanism 6 includes a side output rail frame 61, which is fixed to the suspended side frame 4 and extends into the built-in frame 2. The connecting platform 62 is fixed between the side output rail frames 61, and the tail baffle plate 63 is fixed at the end of the side output rail frame 61 extending into the built-in frame 2. The top bar structure of the connecting platform 62 is set on the top of the connecting platform 62. One end of the top bar structure of the connecting platform 62 has an inclined part. The tray guiding mechanism 6 serves as the displacement guiding structure of the tray carrying mechanism 7. The side output rail frames 61 included in it are distributed in the suspended side frame 4. One part extends completely into the built-in frame 2, while the other part extends to the outside of the built-in frame 2. The two side output rail frames 61 are connected by a structurally stable connecting platform 62, and the end extending into the built-in frame 2 is equipped with a tail baffle plate 63 with a limiting top contact.

[0047] Please see the appendix Figure 1 - Appendix Figure 11The tray carrying mechanism 7 is located on the tray guiding mechanism 6. It works in conjunction with the traction arm structure of the side output rail 61 and the side slide 52, as well as the top bar structure of the connecting platform 62, to carry and transport the radiator frame structure to be installed with cooling pipes. The tray carrying mechanism 7 includes a displacement carrier 71. The displacement carrier 71 is displaced on the side output rail 61 via pulley structures on both sides and can enter the built-in frame 2. A carrying pool 72 is embedded inside the displacement carrier 71. The tray carrying mechanism 7, which is mainly responsible for carrying the radiator frame, has its displacement limited by the tray guiding mechanism 6. The displacement carrier 71, which is limited to the side output rail 61 by pulley structures on both sides, has its displacement limited by pulley structures on both sides. The carrying pool 72 embedded inside the displacement carrier 71 is used to carry the radiator frame. The carrying pool 72 is pre-loaded... When loading the rack material, it will follow the displacement support frame 71 to completely move along the side output rail frame 61 to the outside of the built-in rack 2. After the rack material is embedded in the support pool 72, the displacement support frame 71 is pushed to drive the support pool 72 and the placed rack material into the built-in rack 2. The support pool 72 simultaneously contacts the top bar structure installed on the tail baffle plate 63 and drives the rack material to rise, so that the rack material will be aligned with the evenly spreading assembly mechanism 8 when it enters the built-in rack 2. While the displacement support frame 71 is moving, it will drive the feeding guide mechanism 5 to simultaneously tilt and spread the sheet cooling tube material on the evenly spreading assembly mechanism 8 until the support pool 72 is completely inside the built-in rack 2. Then, the feeding guide mechanism 5 will stop feeding by using the closed-loop slide groove of the guide rail 3.

[0048] Please see the appendix Figure 1 - Appendix Figure 14The evenly spreading assembly mechanism 8 is located on the material tray guiding mechanism 6. It works in conjunction with the side output rail frame 61, the tail baffle plate 63, and the carrying pool 72 to guide the flat stacking of the sheet-like cooling tubes and assemble them synchronously. The evenly spreading assembly mechanism 8 includes relatively distributed evenly spreading assembly components and a top contact push rod 84. The evenly spreading assembly components are relatively distributed on the top of the side output rail frame 61. The top contact push rod 84 is located between the two evenly spreading assembly components and inside the tail baffle plate 63. The evenly spreading assembly components include a side strip fixing frame 81, a side plate 82, and a plate-shaped slide 83. The side strip fixing frame 81 is relatively fixed to the top of the side output rail frame 61 and extends to the side wall of the carrying pool 72. The side plate 82 is fixed to the inside of the side strip fixing frame 81, and the inner side wall is provided with equidistantly distributed guide grooves. The plate-shaped slide 83 slides on the top of the side strip fixing frame 81, and the top contact push rod 84 is fixed to the ends of the two plate-shaped slides 83. The inner side wall of the plate-shaped slide 83 is provided with trapezoidal bearing blocks 86 and straight limit strips 87 arranged oppositely and evenly distributed, and attached to the top of the side plate 82. There is a passage gap between the trapezoidal bearing blocks 86 and the straight limit strips 87. The inner wall of the plate-shaped slide 83 has a stationary retaining strip 85 embedded and sliding. The stationary retaining strip 85 is fixed on the side strip fixing frame 81, and the side wall is fixed with equidistant push inclined blocks 88, which are attached to the top wall of the stationary retaining strip 85 and located between adjacent straight limit strips 87. The top contact push rod 84 is embedded and slides on the tail baffle plate 63, and a retaining spring structure is connected between the tail baffle plate 63 and the side wall of the tail baffle plate 63. Mechanism 8 includes a flat assembly component distributed on the side-mounted output rails 61 on both sides. The flat assembly component includes a fixed and stationary side strip fixing frame 81 and a side plate 82 installed inside the side strip fixing frame 81. The inner side wall of the side plate 82 has an equal number of guide slots arranged in a straight line according to the embedding slot of the radiator frame material. Relative to the stationary side strip fixing frame 81 and the plate-shaped slide 83, the movable plate-shaped slide 83 slides linearly along the top of the side strip fixing frame 81. Similarly, trapezoidal support blocks 86 and straight limit strips 87 are installed in a corresponding and linear arrangement on the side wall near the bearing pool 72. The plate-shaped slide 83 itself can be pushed by the displacement support frame 71 that enters into the built-in frame 2 to move along the side. The top of the edge strip fixing frame 81 slides, and the trapezoidal support block 86 and the straight limiting strip 87 form an angled structure that can tilt and support the sheet-like cooling tubes. Similarly, the stationary retaining strip 85, which is also stationary on the edge strip fixing frame 81, is embedded in the plate-like slide 83. The push-up inclined blocks 88, which are also linearly distributed on the stationary retaining strip 85, correspond to the trapezoidal support blocks 86 that are also linearly distributed. The multiple sets of linearly distributed trapezoidal support blocks 86, straight limiting strips 87 and push-up inclined blocks 88 form an equidistant flat angled structure, which is used to receive the cooling tube raw materials released sequentially by the feeding guide mechanism 5 in the form of tilted support. This initially forms a preliminary flat state for the simultaneous assembly of a large number of cooling tubes, waiting for the support pool 72, which carries the raw materials of the frame, to completely enter the built-in frame 2.Once the support pool 72 is fully inside the built-in frame 2, the displacement support frame 71 pushes against the top contact push rod 84 connecting the two sets of plate-shaped slides 83, causing the top contact push rod 84 and the plate-shaped slides 83 to begin moving inward toward the inside of the built-in frame 2. Simultaneously, the trapezoidal support frame 86 and the straight limiting strip 87, which are inclined to support the cooling pipes, also move synchronously. The relatively stationary stationary retaining strip 85 and the pushing inclined block 88 generate a counter-force, causing the cooling pipes, which are respectively laid flat on the trapezoidal support block 86 and the straight limiting strip 87, to begin centrifugal movement. This continues until the frame material carried in the support pool 72 is in place inside the built-in frame 2. Then, the displacement support frame 71 pushes the plate-shaped slides 83 to move, driving the trapezoidal support block... After 86 and the straight limit bar 87 are completely perpendicular, they begin to fall simultaneously along the guide groove installed on the side wall of the plate-shaped slide 83 into the mounting groove of the frame itself after it has been positioned, thus completing the synchronous assembly of the cooling pipes. This achieves the pre-assembly conveying and flattening alignment of the cooling pipes before the radiator frame is synchronously fed in. After the radiator frame is fully in place, the aligned cooling pipes will be installed into the frame simultaneously. When the radiator frame with assembled cooling pipes is retracted, the cooling pipe material input structure feeding guide mechanism 5 will also return to its original state to await the installation of cooling pipes on the next set of radiator frames. The evenly spreading assembly mechanism 8 and the material tray bearing mechanism 7 will also automatically and synchronously retract to their original states.

[0049] Working Principle: This device mainly assembles finned cooling tubes into automotive radiator frames in batches. The equipment structure is primarily fixed by an external frame 1, while an internal frame 2 serves as the carrier for fixing the entire assembly structure. The raw materials for the finned cooling tubes are input through a feeding guide mechanism 5 that moves at the top of the internal frame 2. The radiator frame materials to be installed are placed on a tray-bearing mechanism 7, which moves along the feeding guide mechanism 5 inside the internal frame 2. After the tray-bearing mechanism 7 completes the loading of the radiator frame components into the internal frame 2, it pushes them into the internal frame 2 along the tray guide mechanism 6. The feeding guide mechanism 5 moves synchronously along the internal frame 2, following the movement of the tray-bearing mechanism 7. The sheet-shaped cooling tubes are fed sequentially in a single-piece manner onto the evenly spreading assembly mechanism 8 mounted on top of the material tray guide mechanism 6 in an inclined, flat manner. As the material guide mechanism 5 moves, the closed-loop groove of the guide rail 3 restricts its movement, driving the material guide mechanism 5 to continuously feed the sheet-shaped cooling tubes until the material tray support mechanism 7, which carries the radiator frame, is fully inserted into the built-in frame 2 along the material tray guide mechanism 6. At this point, the closed-loop groove of the guide rail 3 guides the material guide mechanism 5 to stop feeding simultaneously, and the material tray support mechanism 7 abuts against the components of the evenly spreading assembly mechanism 8, driving the evenly spreading assembly mechanism 8 to operate. Simultaneously, the sheet-shaped cooling tubes laid flat on top of the evenly spreading assembly mechanism 8 are dropped and assembled into the positioned radiator frame, thus completing the cooling tube assembly for the radiator. The automatic assembly process begins, followed by the retraction of the tray-bearing mechanism 7. The feeding guide mechanism 5 then moves along with the tray-bearing mechanism 7 at the top of the internal frame 2 until the tray-bearing mechanism 7 is completely detached from the internal frame 2. After this, the radiator frame with the completed cooling pipe assembly can be retrieved. The feeding guide mechanism 5 also resets along the closed-loop groove of the guide rail 3, awaiting the assembly of a set of frames. The feeding guide mechanism 5, consisting of a horizontal material pipe 51, a medium-diameter material pipe 53, and a small-diameter material pipe 56, forms a conveying pipe structure with a progressively flattened and reduced conveying space. The horizontal material pipe 51 moves linearly at the top of the internal frame 2 via a side slide 52. The traction arm structures on both sides of the side slide 52 are fixed to the end structure of the tray-bearing mechanism 7. When the tray-bearing mechanism 7... As mechanism 7 moves along the guide mechanism 6, it simultaneously moves along the top of the built-in frame 2 using the side-mounted slides 52 installed on both sides. The sheet-like cooling tube raw material pre-loaded inside the horizontal material tube 51 gradually decreases in size through the space via the medium-diameter material tube 53 installed at its bottom output port. The cooling tube raw material carried by the horizontal material tube 51 is guided in small batches along the inclined guide plate 54 into the medium-diameter material tube 53. The small-diameter material tube 56 installed at the bottom output end of the medium-diameter material tube 53 continues to decrease in size through the space, so that the raw material in the medium-diameter material tube 53 continues to be guided by the inclined platform structure at the bottom and enters the small-diameter material tube 56 in a single continuous falling form. Finally, it is laid flat on the evenly spreading assembly mechanism 8 in a single continuous output form along the curved output port at the bottom of the small-diameter material tube 56.The closed-loop chute of guide rail 3 has parallel and inclined chute structures at both ends. When the material tray bearing mechanism 7 drives the raw material of the frame to fully enter the built-in frame 2, the convex shaft structure of the parallel guide rod 55 will also reach the end chute of the closed-loop chute of guide rail 3. The end chute drives the convex shaft structure to move into the upper groove of the closed-loop chute, generating a traction force for the parallel guide rod 55 to rotate. At the same time, the parallel guide rod 55 drives the guide inclined plate 54 to rotate inside the horizontal material tube 51 and abut against the trapezoidal protruding structure installed between the horizontal material tube 51 and the medium diameter material tube 53. The abutting guide inclined plate 54 closes the conveying channel between the horizontal material tube 51 and the medium diameter material tube 53, thereby simultaneously stopping the feeding guide mechanism 5 from uniformly assembling. The top of mechanism 8 conveys flat sheet-like cooling tubes, while the tray guiding mechanism 6 serves as the displacement guiding structure for the tray carrying mechanism 7. Its side-mounted output rails 61 are distributed within the suspended side frame 4, with one part extending completely into the interior of the built-in frame 2 and the other part extending to the outside of the built-in frame 2. A structurally stable connecting platform 62 connects the two side-mounted output rails 61, and a tail-mounted baffle plate 63 with a limiting top contact is added to the end extending into the interior of the built-in frame 2. The tray carrying mechanism 7, which is mainly responsible for supporting the radiator frame, restricts displacement through the tray guiding mechanism 6. Its displacement carrying frame 71 utilizes pulley structures on both sides to restrict displacement on the side-mounted output rails 61, and a carrying pool 7 is embedded inside the displacement carrying frame 71. Two supports are used to carry the radiator frame. When the frame material is pre-loaded, the support pool 72, along with the displacement support frame 71, moves completely to the outside of the internal frame 2 along the side output rail 61. After the frame material is embedded in the support pool 72, the displacement support frame 71 is pushed to drive the support pool 72 and the placed frame material into the internal frame 2. Simultaneously, the support pool 72 contacts the top bar structure added to the tail baffle plate 63, causing the frame material to rise. This ensures that the frame material aligns with the evenly spreading assembly mechanism 8 as it enters the internal frame 2. Simultaneously, the displacement support frame 71 drives the feeding guide mechanism 5 to simultaneously tilt and evenly spread the sheet-like cooling pipe material onto the evenly spreading assembly mechanism 8 until the support pool 72 is completely inside. After the built-in frame 2 is installed, the feeding guide mechanism 5 will stop feeding by using the closed-loop slide groove of the guide rail 3. The evenly spreading assembly mechanism 8 includes a flat spreading assembly component distributed on the side-mounted output rails 61 on both sides. The flat spreading assembly component includes a fixed and stationary edge strip fixing frame 81 and a side plate 82 installed inside the edge strip fixing frame 81. The inner side wall of the side plate 82 has an equal number of guide slots arranged in a straight line according to the embedding slot of the heat sink frame material. Compared with the stationary edge strip fixing frame 81 and the plate-shaped slide 83, the movable plate-shaped slide 83 slides linearly along the top of the edge strip fixing frame 81. Similarly, trapezoidal bearing blocks 86 and straight limit strips 87 are installed in a corresponding and linear arrangement on the side wall near the bearing pool 72.The plate-shaped slide 83 can slide along the top of the side strip fixing frame 81 by contacting and pushing the plate-shaped slide 83 through the displacement bearing frame 71 that enters into the built-in frame 2. The trapezoidal bearing block 86 and the straight limiting strip 87 form an angle structure that can tilt and support the plate-shaped cooling tube. Similarly, the stationary retaining strip 85, which is statically installed on the side strip fixing frame 81, is embedded in the plate-shaped slide 83. The pushing inclined blocks 88, which are also linearly distributed on the stationary retaining strip 85, correspond to the trapezoidal bearing blocks 86 that are also linearly distributed. Multiple sets of linearly distributed trapezoidal bearing blocks 86... The straight limiting strip 87 and the pushing inclined block 88 form an equidistant, flat, angled structure, used to receive the cooling pipe raw materials sequentially released by the feeding guide mechanism 5 in an inclined bearing manner, initially forming a preliminary flat state for the simultaneous assembly of a large number of cooling pipes, waiting for the bearing pool 72 carrying the frame raw materials to fully enter the inner frame 2. Only after the bearing pool 72 is fully inside the inner frame 2 will the displacement bearing frame 71 push against the top contact push rod 84 connecting the two sets of plate-shaped slides 83, driving the top contact push rod 84 and the plate-shaped slides 83 to begin moving inwards towards the inner frame 2. The trapezoidal support frame 86 and the straight limiting strip 87, which are inclined to support the cooling pipes, also move synchronously. The relatively stationary stationary retaining strip 85 and the pushing inclined block 88 generate a counter-force, driving the cooling pipes, which are respectively laid flat on the trapezoidal support block 86 and the straight limiting strip 87, to begin centrifugal movement. After the frame material carried in the support pool 72 is in place inside the built-in frame 2, the displacement support frame 71 pushes the plate-shaped slide 83 to move, driving the trapezoidal support block 86 and the straight limiting strip 87 to be completely vertical, and then they begin to fall simultaneously along the guide groove installed on the side wall of the plate-shaped slide 83. The cooling pipes are then placed into their mounting slots within the rack to complete the synchronous assembly of the cooling pipes. This process allows for the conveying and leveling of the cooling pipes before the radiator rack is simultaneously fed in. Once the radiator rack is fully in place, the leveled cooling pipes are installed into the rack. When the radiator rack with assembled cooling pipes is retracted, the cooling pipe material input structure's feeding guide mechanism 5 also returns to its original state, ready for the next radiator rack to install cooling pipes. Similarly, the evenly spreading assembly mechanism 8 and the material tray carrying mechanism 7 also automatically and synchronously retract to their original states.
