Description

Technical Field

[0001] This application relates to the field of automotive radiator manufacturing equipment technology, and in particular to a crimping machine for sealing end caps of automotive radiators. Background Technology

[0002] In the production and assembly process of automotive radiators, the radiator core and the radiator water chamber need to be fixedly connected. The radiator water chamber is fixedly connected to the two opposite ends of the radiator core, and the crimping is the key process to achieve a reliable connection between the two.

[0003] During the crimping process, existing crimping machines use a combination of two sets of side crimping components, front crimping components, and rear crimping components to simultaneously bend the snapping teeth around the radiator core, forming a crimped cover around the water chamber. However, after completing the crimping of one side, the radiator core needs to be manually removed from the crimping machine and flipped over. Then, the sealing ring and the radiator water chamber are manually placed on the other side of the radiator core and manually fed into the crimping station. The snapping components then simultaneously bend the snapping teeth to form a crimped cover around the water chamber.

[0004] However, after the existing crimping equipment completes the crimping on one side, the operator must manually remove the radiator core, which has a certain weight, from the crimping station, manually rotate it 180°, and then manually place the sealing ring and water chamber on the other side in sequence. Finally, it must be manually put back into the crimping station for a second crimping. The entire manual operation process is time-consuming, resulting in low production efficiency. The manual loading process relies on the operator's visual alignment and experience judgment, which cannot guarantee the repeatability of the core's positioning accuracy at the crimping station. This results in uneven bending of the crimping teeth, reducing the first-pass yield of the products. Summary of the Invention

[0005] This application aims to propose a crimping machine for sealing end caps of automotive radiators, in order to solve the technical problems in related technologies where crimping equipment requires manual removal, flipping, and secondary loading of the workpiece after crimping one side of the water chamber, resulting in low production efficiency, and where manual loading relies on visual alignment and experience judgment, leading to a low first-pass yield of the product.

[0006] In a first aspect, this application provides a crimping machine for sealing end caps of automotive radiators, comprising: The machine body has a receiving cavity arranged along a first direction.

[0009] In some embodiments, the flipping mechanism is located in the area above the opening and closing cavity, wherein the flipping mechanism includes a third telescopic member fixedly connected to the body, a support frame connected to the output end of the third telescopic member, and a spacing adjustment component and a clamping flipping component respectively disposed on the support frame; the two spacing adjustment components are disposed opposite to each other on the support frame, and the clamping portion of the clamping flipping component is installed at the opposite ends of the two spacing adjustment components.

[0010] In some embodiments, the support frame is arranged along the first direction and can be driven to translate in the second direction by the third telescopic member. The two spacing adjustment components are arranged opposite to each other along the first direction, and a clamping and positioning space adapted to the size of the radiator core is formed between the two spacing adjustment components.

[0011] In some embodiments, the spacing adjustment assembly includes a mounting plate disposed on the support frame, a first slide rail disposed on the bottom end face of the mounting plate, a mounting seat slidably connected to the first slide rail, and a fourth telescopic member disposed on the mounting plate and whose output end is fixedly connected to the mounting seat; the fourth telescopic member is used to drive the mounting seat to move along the first slide rail.

[0012] In some embodiments, the clamping and flipping assembly includes a drive motor mounted on the support frame, a transmission rod rotatably connected to the support frame, and a clamping member mounted on the mounting plate; The output end of the drive motor is connected to the transmission rod; the clamping member is rotatably connected to the mounting plate. The transmission rod includes two adjustable rod segments arranged opposite each other. Each adjustable rod segment has at least one guide groove along its length, and a transmission wheel set is sleeved on each adjustable rod segment. At least a portion of the transmission wheel assembly extends into the guide groove so that the transmission wheel assembly can only move along the length direction of the adjustable rod segment, and the transmission wheel assembly is connected to one end of the clamping member in a transmission manner.

[0013] In some embodiments, the transmission wheel assembly includes an adjustment wheel area and a pulley area arranged side by side along the length of the transmission rod; The mounting plate is provided with a driven plate, and the driven plate is provided with a pushing block extending to the adjusting wheel area at one end away from the mounting plate.

The clamping member is provided with a linear guide rail at the end opposite to the transmission belt, and two clamping frames that are slidably connected to the linear guide rail and can slide relative to it.

[0014] In some embodiments, the linear transfer mechanism includes a second slide rail arranged in the receiving cavity along the first direction, a slide seat slidably connected to the second slide rail, and an adsorption member disposed on the slide seat, wherein the length direction of the second slide rail is parallel to the length direction of the guide slide cavity.

[0015] In some embodiments, the adsorption member includes at least two hollow support rods spaced apart in the second direction, and an adsorption element is provided at one end of the two hollow support rods facing the flipping station. The adsorption element can selectively actuate with the end face of the radiator core. When the sliding seat slides along the second slide rail, the two hollow support rods move synchronously along the first direction.

[0016] Compared with the prior art, the technical solution provided in the first aspect of this application has at least the following beneficial effects or advantages: The crimping machine provided in this application integrates a linear transfer mechanism, a crimping fixture, a support mechanism, and a flipping mechanism by setting a receiving cavity along a first direction in the machine body. The linear transfer mechanism smoothly transfers along the first direction, driving the radiator core into the guide slide cavity of the crimping fixture and transferring it from the crimping station to the flipping station. The guide slide cavity is formed by two opposing guide support plates, whose support surfaces precisely support the lower edges of both ends of the radiator core. This not only prevents the core from collapsing due to uneven force during transportation but also provides lateral guidance and limitation for the core mainboard through the inner side of the guide support plates, allowing the core to automatically complete centering during transportation without manual intervention. After completing the single-sided crimping and transfer to the opening and closing cavity, the two clamping components of the opening and closing assembly move synchronously towards each other to the first preset space. The lifting component of the support mechanism extends upward from inside the receiving cavity, with its lifting end supporting the lower surface of the mainboard at both ends of the core. This smoothly lifts the core, after single-sided clamping, to a preset flipping height. The flipping mechanism then moves downward and clamps the core from both sides. After clamping and fixing, the two clamping components of the opening and closing assembly move synchronously towards each other to a second preset distance. The flipping mechanism then moves the core upward and smoothly flips it. Once flipped in place, the lifting component supports the flipped core again and lowers it to a preset height. The opening and closing assembly clamps simultaneously, ensuring that the opening and closing cavity and the guide slide cavity are aligned on the same straight line. This complete automatic flipping process completely replaces all manual removal, flipping, and secondary loading operations, reducing waiting time and manual intervention between processes and improving production efficiency. Simultaneously, it avoids positional and angular deviations caused by manual visual alignment, resulting in more uniform bending of the clamping teeth around the radiator core and improving the first-pass yield of the product. In addition, the entire operation process does not require operators to put their hands into the equipment clamping area, reducing the number of times the radiator core with a certain weight is manually moved, reducing the labor intensity of operators, and avoiding the safety hazards caused by equipment clamping.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0026] Please see Figure 1The radiator 200 mainly consists of a radiator core 201, two symmetrically arranged radiator water chambers 202 (end caps), and two sealing rings 204. The upper and lower edges of the radiator core 201 are stamped with several evenly distributed snap-fit ​​teeth 203 for mechanically fastening with the radiator water chambers 202. During assembly, one sealing ring 204 is first placed on one end face of the radiator core 201, and then the corresponding radiator water chamber 202 is snapped onto the sealing ring 204, aligning the flange edge of the radiator water chamber 202 with the end face edge of the radiator core 201. Subsequently, all the snap-fit ​​teeth 203 on this end are simultaneously bent using a crimping machine, so that the snap-fit ​​teeth 203 tightly wrap around the flange edge of the radiator water chamber 202, thereby achieving the sealing and fixing of the radiator core 201 and the single-sided radiator water chamber 202. After the crimping connection of the single-sided radiator water chamber 202 is completed, the radiator core 201 needs to be rotated 180° as a whole, and the above-mentioned processes of laying the sealing ring 204, snapping the radiator water chamber 202 and bending the snap-fit ​​teeth 203 are repeated to complete the assembly of the entire radiator 200. However, as mentioned earlier, after the existing crimping equipment completes the crimping on one side, the operator must manually remove the radiator core, which has a certain weight, from the crimping station, manually rotate it 180°, and then manually place the sealing ring and water chamber on the other side in sequence. Finally, it must be manually put back into the crimping station for a second crimping. The entire manual operation process is time-consuming, resulting in low production efficiency. The manual loading process relies on the operator's visual alignment and experience judgment, which cannot guarantee the repeatability of the core's positioning accuracy at the crimping station. This results in uneven bending of the crimping teeth, reducing the first-pass yield of the product.

[0027] Based on this, the inventors propose a crimping machine for sealing end caps of automotive radiators, which enables the equipment to automatically remove, flip, and reload the radiator core, and eliminates the need for manual visual alignment and experience-based judgment during the loading process, thereby improving product production efficiency and first-pass yield. The crimping machine will be further described below with reference to several embodiments.

[0028] Please see Figures 2 to 4This embodiment provides a crimping machine for sealing end caps of automotive radiators. The crimping machine 100 includes a body 10, a crimping fixture 20, a support mechanism 30, and a flipping mechanism 40. The crimping machine 100 can be rectangular. For ease of description, the length direction of the crimping machine 100 is defined as the first direction A, the height direction as the second direction B, and the width direction as the third direction C. The body 10 has a receiving cavity 11 extending along the first direction A inside. The top of the body 10 is divided into a flipping station 101 and a crimping station 102 above the receiving cavity 11. The receiving cavity 11 is opened at one end along the first direction A for transferring the radiator to the crimping machine 100. A linear transfer mechanism 12 is installed at the end of the receiving cavity 11 away from the opening and is used to drive the radiator core to reciprocate between the flipping station 101 and the crimping station 102 along the first direction A.

[0029] Furthermore, the clamping fixture 20 is fixedly installed on the machine body 10, including two opposing guide support plates 21, forming a narrow guide slide cavity 211 between the two guide support plates 21. The bottom of the guide slide cavity 211 is connected to the receiving cavity 11, and its length direction is consistent with the first direction A. A portion of the guide slide cavity 211 extends into the clamping station 102, used to continuously support and laterally limit the radiator core during movement. The support mechanism 30 includes a lifting component 31 and an opening and closing component 32. The lifting component 31 is disposed in the receiving cavity 102. The opening and closing assembly 32 is fixedly installed on the top surface of the machine body 10 and located at the flipping station 101. The opening and closing assembly 32 includes two clamping members arranged opposite to each other, and the two clamping members form an opening and closing cavity 323 that is coaxially connected with the guide slide cavity 211. The flipping mechanism 40 is installed on the top surface of the machine body 10 and located directly above the opening and closing cavity 323. It can cooperate with the lifting assembly 31 and the opening and closing assembly 32 in the second direction B to complete the automatic removal, flipping and resetting of the radiator core in the opening and closing cavity 323.

[0030] It should be noted that the two guide support plates 21 are elongated arc-shaped plates, specifically, with an arc-shaped outer contour. A narrow guide cavity 211 is formed between the two guide support plates 21, the width of which matches the concave structure near the end of the radiator core. That is, the width of the rigid main plates at both ends of the radiator core is greater than the overall width of the middle heat dissipation strip and heat pipes. Concave steps extending along the length direction are formed on both sides of the core. The width of the guide cavity 211 exactly matches the width of the main plates at both ends and is greater than the overall width of the middle heat dissipation structure. During operation, when the radiator core enters the guide cavity 211, the top and inner walls of the two guide support plates 21 only contact the sides of the main plates at both ends of the core, providing lateral restraint to the core. The heat dissipation strip and heat pipes in the middle of the core are completely suspended in the area between the two guide support plates 21, without contacting any other components. When the core moves along the first direction A in the guide slide cavity 211, the sides of the two main boards slide smoothly along the inner sidewall of the guide support plate 21, automatically maintaining a linear motion state without the need for additional guide mechanisms.

[0031] During operation, the linear transfer mechanism 12 transports the pre-installed radiator core on one side to the crimping station 102 to complete the first crimping. Then, it transports the core to the opening and closing cavity 323 of the flipping station 101. Initially, the width of the opening and closing cavity 323 is the same as the width of the guide slide cavity 211. The opening and closing component 32 first opens horizontally to the first preset position, and the lifting component 31 lifts the core upward to the first preset height. The flipping mechanism 40 descends and clamps and fixes both ends of the core. The opening and closing component 32 then opens horizontally to the second preset position to avoid the flipping path. The flipping mechanism 40 drives the core upward to the second preset height and completes a 180-degree flip. Then, it descends and resets in sequence, placing the flipped core back into the guide slide cavity 211. Finally, the linear transfer mechanism 12 transports the core back to the crimping station 102 to complete the crimping of the other side of the water chamber.

[0032] The crimping machine 100 provided in this embodiment integrates a linear transfer mechanism 12, a crimping fixture 20, a support mechanism 30, and a flipping mechanism 40 by setting a receiving cavity 11 along the first direction A in the machine body 10. The linear transfer mechanism 12 smoothly transfers along the first direction A, driving the radiator core into the guide slide cavity 211 of the crimping fixture 20 and from the crimping station 102 to the flipping station 101. The guide slide cavity 211 is formed by two oppositely arranged guide support plates 21, whose support surfaces are exactly supported on the lower edges of both ends of the radiator core. This not only avoids the core falling over due to uneven force during transportation, but also forms a lateral guide limit on the core main board through the inner side of the guide support plate 21, so that the core automatically completes the centering during transportation without manual intervention. After completing the single-sided crimping and transfer to the opening and closing cavity 323, the two clamping components of the opening and closing assembly 32 synchronously... The lifting components 31 of the supporting mechanism 30 extend upward from inside the receiving cavity 11, moving towards each other to the first preset distance. Their lifting ends support the lower surfaces of the main boards at both ends of the core, smoothly lifting the core, which has completed single-sided clamping, to the preset flipping height. The flipping mechanism 40 moves downward and clamps the core from both sides. After clamping and fixing, the two clamping components of the opening and closing assembly 32 move towards each other again synchronously to the second preset distance. The flipping mechanism 40 drives the core upward and completes the smooth flipping of the core. After flipping to the correct position, the lifting component 31 supports the flipped core again and lowers it to the preset height. The opening and closing assembly 32 clamps synchronously, ensuring that the opening and closing cavity 323 and the guide slide cavity 211 are on the same straight line. This complete automatic flipping process completely replaces all manual removal, flipping, and secondary loading operations, reducing waiting time and manual intervention between processes and improving production efficiency. Simultaneously, it avoids positional and angular deviations caused by manual visual alignment, making the bending amount of the clamping teeth around the radiator core more uniform and consistent, thus improving the first-pass yield of the product. In addition, the entire operation process does not require operators to put their hands into the equipment clamping area, reducing the number of times the radiator core with a certain weight is manually moved, reducing the labor intensity of operators, and avoiding the safety hazards caused by equipment clamping.

[0033] Optional, please continue reading Figures 2 to 4The clamping fixture 20 also includes a clamping assembly 22 mounted on the surface of the machine body 10 and a pressing assembly 23 located above the guide slide cavity 211. The clamping assembly 22 includes multiple sets of first telescopic cylinders 221, which are symmetrically mounted on the outer surface of the machine body 10 along the third direction C of the two limiting support plates. The telescopic direction of each set of first telescopic cylinders 221 is set along the third direction C, and its output end faces the center of the guide slide cavity 211 and is fixedly connected to a pressure block 222. The side of the pressure block 222 facing the limiting support plate is machined with a concave arc surface, which is perfectly matched with the outline of the convex arc surface at the corresponding position of the outer wall of the limiting support plate, forming a mating relationship. The end of the pressure block 222 facing the guide slide cavity 211 is provided with a pressing part, and the working surface of the pressing part matches the preset bending angle of the clamping teeth.

[0034] Furthermore, the clamping assembly 23 includes multiple second telescopic cylinders 231 spaced apart along the first direction A. All second telescopic cylinders 231 can be fixedly installed above the guide slide cavity 211 via a gantry bracket, with their telescopic direction vertically downward along the second direction B. Each cylinder's output end is fixedly connected to a rubber pressure head 232. The lower surface contour of the rubber pressure head 232 is adapted to the partial upper surface contour of the radiator water chamber, enabling uniform clamping of the radiator water chamber.

[0035] During operation, before the crimping assembly 22 is activated, all second telescopic cylinders 231 extend synchronously, driving the rubber pressure head 232 to press down smoothly against the upper surface of the water chamber, so that the sealing ring between the water chamber and the core end face is tightly fitted and reaches the preset compression amount. After the radiator core with the pre-installed water chamber and sealing ring is transported to the crimping station 102, all first telescopic cylinders 221 extend synchronously, driving the pressure block 222 to slide smoothly along the outer convex arc surface of the limiting support plate. The pressure head contacts and bends the snapping teeth around the core at a preset angle, so that the snapping teeth bend evenly along the tooth root position towards the center of the water chamber flange, and finally tightly wraps around the upper surface of the water chamber flange, forming a mechanical self-locking structure. After the crimping assembly 22 completes the bending action of all snapping teeth and resets, the second telescopic cylinders 231 retract synchronously, releasing the crimped core and completing the single-sided crimping operation.

[0036] This configuration, with its arc-shaped sliding fit structure between the pressure block 222 and the limiting support plate, precisely limits the movement trajectory of the pressure block 222 from a mechanical perspective. This ensures the pressure head always contacts the engagement teeth at the optimal angle and force, maintaining a high degree of consistency in the bending amount and angle of all engagement teeth. This effectively avoids quality problems such as overpressure breakage of engagement teeth, insufficient pressing, or bending angle deviation, thus improving the structural reliability of the crimping connection. Secondly, the collaborative working mechanism of the pressing component 23 and the crimping component 22 maintains the water chamber and core in a compressed state throughout the entire crimping process. This prevents the water chamber from shifting, tilting, or deviating under the lateral force generated by the bending of the engagement teeth, ensuring that the compression of the sealing ring is evenly distributed across the entire sealing surface, thereby improving the radiator's sealing performance. Compared to existing technologies that require manual assistance in pressing the water chamber, this embodiment achieves fully automated synchronous operation of pressing and crimping, eliminating manual intervention and further improving production efficiency and product quality consistency.

[0037] In some embodiments, please refer to Figure 2 and Figure 4 The linear transfer mechanism 12 includes a second slide rail 121 arranged along the first direction A within the receiving cavity 11. Specifically, the second slide rail 121 can be installed on the inner wall of the receiving cavity 11. A sliding seat 122 is slidably connected to the second slide rail 121. The second slide rail 121 can be driven by a drive member 1211 in cooperation with a lead screw. The lead screw is connected to the sliding seat 122. The drive member 1211 can be a servo motor and is located at one end of the second slide rail 121. An adsorption component is fixedly installed on the sliding seat 122. The length direction of the second slide rail 121 is parallel to the length direction of the guide slide cavity 211. One end of the second slide rail 121 can extend to near the flipping station 101, and the other end extends below the crimping station 102, covering the entire core conveying path. During operation, the sliding seat 122 is powered by the motor to slide back and forth along the second slide rail 121, driving the adsorption component to move along the first direction A between the flipping station 101 and the crimping station 102, thereby realizing the automated conveying of the radiator core.

[0038] In this embodiment, the linear transfer mechanism 12, arranged parallel to the guide cavity 211, enables automated continuous conveying of the core between the flipping station 101 and the crimping station 102. The conveying process is smooth and stable with high positioning accuracy, significantly improving production efficiency. The linear transfer mechanism 12 is located inside the receiving cavity 11, not occupying the working space above the equipment, making the overall structure more compact and the footprint smaller, facilitating layout on the production line. More importantly, the coordinated work of the linear transfer mechanism 12, the flipping mechanism 40, and the crimping fixture 20 achieves fully automated production of the radiator core with double-sided crimping, requiring no manual intervention and improving the automation level of the production line.

[0039] In some embodiments, please refer to Figure 3 and Figure 4 The top surface of the body 10 is provided with guide grooves 13 arranged parallel to the third direction C. The guide grooves 13 are located on both sides of the opening and closing cavity 323. Multiple guide grooves 13 can be opened at intervals along the first direction A. In this embodiment, two guide grooves 13 are provided. The clamping component of the opening and closing assembly 32 includes second telescopic members 321 symmetrically arranged along the third direction C. Multiple second telescopic members 321 can be provided. The cylinders of multiple second telescopic members 321 are fixedly installed on the surface of the body 10, and their output ends extend towards the center of the opening and closing cavity 323 and are fixedly connected to the outer wall of the opening and closing clamping plate 322. At least one slider is fixedly installed on the bottom end face of each opening and closing clamping plate 322. The slider is embedded in the corresponding guide groove 13 and slides with it, forming a precise linear guide for the movement of the opening and closing clamping plate 322. During operation, multiple second telescopic members 321 extend or retract simultaneously, driving the two opening and closing clamping plates 322 to move towards or away from each other along the guide groove 13, realizing the clamping and release of the edges of the main board on both sides of the core.

[0040] It should be noted that the second telescopic component 321 can be a hydraulic cylinder or a telescopic electric cylinder, the opening and closing clamping plate 322 is a long strip plate, the opening and closing assembly 32 has multiple working states, and the width of the opening and closing cavity 323 formed between them changes with the switching of working states. When the second telescopic components 321 on both sides drive the opening and closing clamping plate 322 to be in the clamping state, the opening and closing clamping plate 322 is located in the first preset position. At this time, the width of the opening and closing cavity 323 and the guide slide cavity 211 can be equal and located on the same straight line. When it is necessary to flip, the second telescopic components 321 on both sides drive the opening and closing clamping plate 322 to move in the opposite direction, so that the opening and closing clamping plate 322 is located in the second preset position. At this time, the width of the opening and closing cavity 323 is greater than the width of the guide slide cavity 211, and is also greater than the maximum width of the radiator core.

[0041] In an alternative embodiment, the second telescopic member 321 can also adopt a transmission form of servo motor and ball screw, and realize closed-loop control of clamping force through torque feedback. The clamping surface of the opening and closing clamping plate 322 can be inlaid with a wear-resistant elastic layer, which can increase the clamping friction and avoid scratching the surface coating of the core motherboard.

[0042] In this embodiment, the precise guidance of the guide groove 13 and the slider ensures that the two opening and closing clamping plates 322 always move in parallel, and the clamping force is evenly distributed on the edges of the main board on both sides of the core, without causing any torsional stress on the core. The coordinated action of the opening and closing assembly 32 and the lifting assembly 31 forms a dual positioning of the core. Before the flipping mechanism 40 clamps the core, the opening and closing assembly 32 always remains in a clamping state, preventing the core from tipping over or slipping during the lifting process, thus improving the safety of equipment operation.

[0043] In some embodiments, please refer to Figure 3 and Figure 5 The lifting assembly 31 includes a base 311 fixedly installed at the bottom of the receiving cavity 11. A first telescopic member 312 and cross-arranged brackets are installed on the base 311. The bottom end of the bracket connected to the output end of the first telescopic member 312 is slidably connected to the base 311, and the top of the cross-arranged brackets is fixedly connected to a horizontally arranged support plate 313. The first telescopic member 312 and the support plate 313 are both located within the projection range directly below the opening and closing cavity 323, ensuring that the lifting force can act vertically on the bottom of the core. The top surface of the support plate 313 can be machined with a support structure that is completely adapted to the contour of the motherboard at the bottom of the heat sink core, so that the support plate 313 contacts the rigid motherboard lower surface at both ends of the core.

[0044] It should be noted that the first telescopic component 312 can be a hydraulic cylinder or a pneumatic cylinder. The connection between the two ends of the first telescopic component 312 is a rotatable connection. During operation, the first telescopic component 312 extends and retracts synchronously, driving the support plate 313 to move vertically upward or downward, and smoothly lifting the radiator core located in the guide slide cavity 211 to the preset flipping height. After the flipping is completed, the first telescopic component 312 retracts synchronously and uniformly, driving the support plate 313 to smoothly place the core back onto the support surface of the guide slide cavity 211.

[0045] In this embodiment, a support structure adapted to the contour of the core motherboard is adopted, concentrating all lifting force on the rigid bearing part of the core. The synchronous drive of the first telescopic component 312 ensures that the support plate 313 always remains horizontal, and the core avoids tilting or shaking during the lifting process, providing a stable reference for the precise clamping of the subsequent opening and closing component 32, and further improving the positioning accuracy of subsequent processes.

[0046] In an alternative embodiment, the first telescopic member 312 can employ a servo drive element with built-in displacement feedback, enabling real-time monitoring and precise control of the lifting height. An elastic buffer layer can be adhered to the supporting surface of the support plate 313 to cushion the impact force during lifting and prevent the core from sliding on the plate. For multi-product production scenarios, the support plate 313 can be designed as a quick-change structure, connecting to the output end of the first telescopic member 312 via a quick-connect structure, allowing for rapid replacement to adapt to different models of radiator cores.

[0047] In some embodiments, please refer to Figure 3 and Figure 5The adsorption component includes at least two hollow support rods 123 spaced apart in the second direction B. Each of the two hollow support rods 123 has an adsorption element 1231 at one end facing the flipping station 101. The adsorption element 1231 can be an adsorption plate. The adsorption plate can selectively generate negative pressure to attract the end face of the radiator core. When the sliding seat 122 slides along the second slide rail 121, the two adsorption support rods move synchronously along the first direction A, causing the adsorption plate and the adsorbed core to move together.

[0048] Optionally, a displacement sensor 124 can also be installed on the sliding seat 122. The displacement sensor 124 is used for positioning the sliding seat 122 during the sliding process. For the uneven end face of the core, an array of suction cups composed of multiple small suction cups can be used to improve the reliability of the adsorption. For the heat sink core made of all-metal material that can be attracted by magnets, the suction cups can also be replaced with an electromagnetic adsorption device. By adsorbing the end face of the core through electromagnetic force, stable delivery can also be achieved.

[0049] In this implementation, the end-face adsorption conveying method, compared to the shortcomings of the existing claw-type conveying method which easily damages the core edges and snap-fit ​​teeth, ensures that the adsorption force is evenly applied to the end face of the core, preventing mechanical damage to any part of the core and effectively protecting the core's heat dissipation structure and pre-formed snap-fit ​​teeth. Multiple spaced hollow support rods 123 provide multi-point adsorption force, resulting in a more secure and reliable adsorption, reducing core shaking or detachment during conveying, ensuring accurate conveying position, and providing a good positioning reference for subsequent crimping processes. Furthermore, the adsorption method has the advantages of small footprint and fast response speed.

[0050] In some embodiments, please refer to Figure 3 and Figure 6 The flipping mechanism 40 is located directly above the opening and closing cavity 323. It includes a third telescopic member 41 vertically fixedly mounted on the machine body 10. The output end of the third telescopic member 41 extends downward and is fixedly connected to the support frame 42. Multiple third telescopic members 41 can be provided, for example, two are provided in this embodiment. The third telescopic member 41 can be either a hydraulic cylinder or a pneumatic cylinder. Two sets of spacing adjustment components 43 and a set of clamping and flipping components 44 are mounted on the support frame 42. The two sets of spacing adjustment components 43 are arranged opposite to each other along the first direction A. The two clamping parts of the clamping and flipping components 44 are respectively installed on the opposite inner ends of the two sets of spacing adjustment components 43.

[0051] The collaborative working process of the flipping mechanism 40, lifting component 31, and opening / closing component 32 in the second direction B is as follows: When the core needs to be flipped, the opening / closing component 32 first opens horizontally to the first preset position, and the lifting component 31 lifts the radiator core upward to the first preset height; the third telescopic component 41 extends and drives the support frame 42 to descend, clamping the flipping component 44 from both ends of the core; the opening / closing component 32 then opens horizontally to the second preset position, completely avoiding the flipping path of the core; the third telescopic component 41 continues to retract, driving the core to rise to the second preset height, clamping the flipping component 44 and driving the core to complete a 180-degree flip; after the flip is in place, the third telescopic component 41 extends and places the core back onto the support plate 313 of the lifting component 31, the clamping flipping component 44 is released, and the opening / closing component 32 resets, completing the entire flipping and reset process.

[0052] In this embodiment, the core flipping process is fully automated by precisely coordinating the flipping mechanism 40 with the lifting component 31 and the opening and closing component 32 in a step-by-step manner. This replaces all manual operations of removing, flipping, and reloading, significantly reducing waiting time between processes, improving production efficiency, and eliminating the labor intensity and safety hazards associated with manually handling heavy objects. Throughout the flipping process, the core remains firmly clamped. Simultaneously, this coordinated process ensures the consistency of the core's position before and after flipping, eliminating positioning errors caused by manual reloading and ensuring complete uniformity of the positioning references for the two crimping processes, thereby improving the consistency of crimping quality.

[0053] In some embodiments, continue reading Figure 6 The support frame 42 extends along the first direction A and has sufficient length to cover the size range of different specifications of heat sink cores. The third telescopic member 41 can drive the support frame 42 to move vertically back and forth along the second direction B. Two sets of spacing adjustment components 43 are respectively installed at both ends of the support frame 42 along the first direction A, and are arranged opposite to each other along the first direction A. The clamping ends of the two sets of spacing adjustment components 43 form a clamping and positioning space adapted to the size of the heat sink core. During operation, according to the length of the core to be processed, the two sets of spacing adjustment components 43 can automatically adjust their relative positions to match the length of the clamping and positioning space with the length of the core, ensuring that the clamping and flipping component 44 can accurately clamp the motherboard parts at both ends of the core.

[0054] This configuration, with the support frame 42 arranged along the first direction A and the opposing spacing adjustment components 43, allows for flexible adjustment of the clamping and positioning space, covering various specifications of radiator cores and improving the equipment's versatility. Clamping is performed from both ends of the radiator core, requiring less workspace and resulting in a more uniform distribution of clamping force, ensuring flipping accuracy and product quality. Simultaneously, this symmetrical arrangement ensures that the support frame 42 experiences balanced forces during flipping, preventing the generation of additional bending moments and torques, thus improving the stability and reliability of the equipment.

[0055] In some embodiments, please refer to Figure 7 The spacing adjustment component 43 includes a mounting plate 431 fixedly mounted on the bottom surface of the support frame 42. A first slide rail 4311 is fixedly provided on the bottom surface of the mounting plate 431 along the first direction A, and a mounting seat 432 is slidably connected to the first slide rail 4311. A fourth telescopic member 433 is fixedly mounted on one end of the mounting plate 431. The output end of the fourth telescopic member 433 extends along the first direction A and is fixedly connected to the side wall of the mounting seat 432. The fourth telescopic member 433 can be either a hydraulic cylinder or a pneumatic cylinder. The clamping part of the clamping and flipping component 44 is fixedly mounted on the inner end of the mounting seat 432 and can move synchronously with the mounting seat 432 along the first slide rail 4311. During operation, the fourth telescopic member 433 extends or retracts, causing the mounting seat 432 to slide back and forth along the first slide rail 4311, thereby adjusting the relative distance between the two mounting seats 432 and realizing stepless adjustment of the clamping positioning space length. Once adjusted to the correct position, the fourth telescopic component 433 remains in its current state, using its own self-locking force to lock the mounting base 432 in its current position.

[0056] In one example, the fourth telescopic component 433 can also employ a servo motor coupled with a ball screw transmission to achieve stepless adjustment of the spacing. The first slide rail 4311 can be a high-precision linear guide rail used in conjunction with a ball slider to obtain higher motion accuracy and lower frictional resistance. Furthermore, an additional locking mechanism can be provided on the mounting base 432 to further lock the mounting base 432 onto the first slide rail 4311 after the spacing adjustment is complete, improving the reliability of the locking.

[0057] The spacing adjustment component 43 provided in this embodiment, driven by the electric adjustment structure of the fourth telescopic member 433, enables one-click switching for product changeover, shortening changeover time and improving production efficiency. The guiding function of the first slide rail 4311 ensures the straightness of the movement of the mounting base 432, keeping the two clamping ends coaxial and preventing core distortion caused by misalignment, thus ensuring the stability of the flipping process. Furthermore, the self-locking function of the fourth telescopic member 433 ensures that the clamping spacing remains constant during flipping, preventing the core from falling off due to loose clamping and improving the safety of equipment operation.

[0058] In some embodiments, please refer to Figure 8 The clamping and flipping assembly 44 includes a drive motor 441 fixedly mounted on a support frame 42, a transmission rod 442 rotatably connected to the support frame 42 along a first direction A, and a clamping member 443 disposed on a mounting plate 431. The transmission rod 442 includes two adjustable rod segments 4421 arranged opposite each other, and the two adjustable rod segments 4421 are coaxial to form a complete transmission rod 442. Each adjustable rod segment 4421 has at least one limiting groove 44211 along its length direction, and each adjustable rod segment 4421 is fitted with a transmission wheel set 444. At least a portion of the transmission wheel set 444 extends into the limiting groove 44211, so that the transmission wheel set 444 can only move along the length direction of the adjustable rod segment 4421 and cannot rotate relative to the transmission rod 442. The transmission wheel set 444 is drively connected to the clamping member 443 on the corresponding side. During operation, the drive motor 441 drives the transmission rod 442 to rotate, and the transmission rod 442 drives the transmission wheel set 444 to rotate synchronously through the limiting groove 44211. The transmission wheel set 444 then drives the clamping component 443 to rotate, thereby realizing the flipping of the core. When the spacing adjustment component 43 drives the mounting base 432 to move, the transmission wheel set 444 moves synchronously along the limiting groove 44211, always maintaining the transmission connection with the transmission rod 442.

[0059] In this embodiment, a single-motor driven adjustable transmission rod 442 structure is adopted to simultaneously drive the two clamping components 443 to rotate synchronously, ensuring absolute synchronicity of the flipping actions at both ends and avoiding core distortion caused by asynchronous rotation at both ends. The transmission wheel set 444 can move along the limiting groove 44211 with the spacing adjustment component 43, ensuring uninterrupted transmission during the adjustment of the clamping spacing. This achieves universal flipping drive for cores of different lengths, with a simple and compact structure and high reliability. At the same time, it reduces the complexity of the control system and improves the stability of equipment operation.

[0060] In some embodiments, continue reading Figure 8 The transmission wheel assembly 444 includes an adjusting wheel area 4441 and a pulley area 4442 arranged side-by-side along the length of the transmission rod 442. A driven plate 4321 is fixedly mounted on the mounting plate 431. One end of the driven plate 4321 opposite to the mounting plate 431 extends to the adjusting wheel area 4441 and is provided with a pushing block 43211 that cooperates with the adjusting wheel area 4441. The pulley area 4442 is connected to the clamping member 443 via a transmission belt. When the mounting plate 431 moves along the first direction A, the pushing block 43211 on the driven plate 4321 drives the transmission wheel assembly 444 to move synchronously along the transmission rod 442, ensuring that the relative position of the pulley area 4442 and the clamping member 443 remains unchanged, thereby maintaining the tension of the transmission belt.

[0061] Furthermore, a linear guide rail 4431 is provided at the end of the clamping member 443 away from the transmission belt. The linear guide rail 4431 can be an electromagnetic slide rail. The electromagnetic slide rail generates a magnetic field when an electromagnetic coil is set inside the rail. This magnetic field interacts with the magnetic material inside the slider, thereby generating a driving force that makes the slider slide along the rail. This achieves a contactless, smooth, and quiet sliding effect. Two relative clamping frames 4432 are slidably connected on the guide rail. Since the clamping member 443 is arranged opposite to each other, a clamping space area for the radiator core is formed between the two clamping frames 4432. The clamping frames 4432 can be flat and are adapted to the opposite end faces of the radiator core along the thickness direction. In this embodiment, the width of the clamping frame 4432 can be adapted to the width of the flat surface of the radiator core along the height direction. This allows the clamping frames 4432 to abut against the deformation area of ​​the radiator core along the opposite ends of the width, achieving stable clamping of the radiator core.

[0062] Optionally, rolling elements can be installed at the contact points between the push block 43211 and the adjusting wheel area 4441 to convert sliding friction into rolling friction, reducing resistance during the movement of the transmission wheel set 444. A synchronous belt can be used with a synchronous pulley to eliminate slippage during transmission and improve the transmission accuracy of the tilting angle. Furthermore, the clamping frame 4432 is controlled by a rigid plate structure to improve clamping reliability.

[0063] This design, through the driven plate 4321 and the pusher block 43211, allows the transmission pulley set 444 to move synchronously with the pitch adjustment component 43, maintaining a constant tension in the transmission belt without manual intervention. This simplifies the equipment structure and reduces maintenance costs. Simultaneously, the sliding clamping frame 4432 can flexibly adjust the clamping width to accommodate radiator cores of different widths, further expanding the equipment's applicability. The clamping frame 4432 clamps the core from the sides of the main board at both ends, ensuring even clamping force distribution without damaging the core's heat dissipation structure or pre-formed engagement teeth, thus protecting product quality.
