Description
Technical fields:
[0001] This utility model relates to the field of radiator assembly technology, and specifically to a radiator fastening mechanism. Background technology:
[0002] A heatsink is a key component in computer hardware used to control the temperature of core components such as the CPU and GPU. It dissipates heat rapidly through heat conduction (e.g., a copper base), convection (fans / liquid cooling circulation), and radiation. Depending on the application, heatsinks are mainly divided into:
[0003] Air-cooled heatsinks: These use aluminum / copper fins with fans, are low-cost and easy to maintain, and are commonly found in ordinary PCs;
[0004] Water-cooled radiators: achieve efficient heat dissipation through liquid pumps and radiators, suitable for high-performance CPUs or overclocking needs;
[0005] Server-specific coolers emphasize high-density heat dissipation designs, such as turbine fans, vapor chambers, or multi-heatpipe arrays, and must be compatible with rack-mount environments. Coolers are typically secured to the processor using mounting hardware (such as Intel LGA / AMD AM mounts) to ensure a tight fit between the heatsink base and the chip surface. These hardware components include metal spring screws or plastic clips, and must be compatible with motherboard mounting holes and have balanced pressure distribution to optimize thermal conductivity.
[0006] When installing a heatsink, locking fasteners are typically used to mount it onto the motherboard. For example, Chinese patent application CN103906406A discloses a heatsink assembly including a base, a heat pipe, a first heatsink, and a second heatsink. The heat pipe includes a positioning part fixed to the base and a heat-conducting part inserted into the first heatsink. The second heatsink is fixed between the base and the first heatsink. This arrangement of the second heatsink between the base and the first heatsink enhances airflow resistance, allowing for more efficient heat exchange and improved cooling efficiency. The base includes a main body and a connector, with a locking fastener at each of the four corners to secure the main body to the motherboard. For larger heatsinks, fasteners with the same structure as the locking fasteners are also used for assembling the fins and terminals. The fastening components include a screw, a spring, a sleeve, and a retaining ring. First, the sleeve and spring are put onto the screw, then the screw is connected to the mounting position of the radiator. The radiator is assembled and fixed by fastening the retaining ring onto the screw.
[0007] However, most fastener installations on the market are currently done manually, which is not only inefficient and labor-intensive, but also requires multiple fasteners for each radiator assembly, making manual assembly prone to errors and injuries.
[0008] In view of the above, the inventors propose the following technical solution. Utility model content:
[0009] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a radiator fastening mechanism.

[0013] Furthermore, in the above technical solution, the first T-shaped guide bar is also equipped with a counterweight block for pressing against the retaining ring to push the retaining ring to automatically feed the material.
[0014] Furthermore, in the above technical solution, the first support frame is also vertically provided with two first guide rods for guiding the movement and positioning of the lifting seat, and the first support frame is provided with at least two first guide seats that are spaced apart and positioned for the first guide rods; a first connecting rod is provided between the second cylinder and the lifting seat.
[0015] Furthermore, in the above technical solution, the lifting seat is provided with four stacking uprights, and the four stacking uprights are arranged around the periphery of the lifting seat. The base plate, the stacking uprights, the pusher plate and the first cylinder are respectively provided in four units.
[0016] Furthermore, in the above technical solution, the bearing positioning platform includes a support base, a lifting platform floating on the support base, a positioning fixture on the lifting platform for positioning the radiator module, a third cylinder and a fourth cylinder located below the lifting platform for pushing its lifting movement, a lifting rod frame located below the lifting platform and capable of penetrating the lifting platform to eject the screw, a fifth cylinder located on the support base for pushing the lifting rod frame, at least two locking devices located on the support base for locking and supporting the lifting platform to withstand pressure, and a drive block that moves synchronously with the third cylinder and the fourth cylinder to push the locking devices to lock the raised lifting platform.
[0017] Furthermore, in the above technical solution, multiple guide positioning rods are provided below the lifting platform. The locking device includes a limiting base sleeved on the guide positioning rod, a sliding limiting block slidably disposed on the limiting base, and a locking spring disposed on the limiting base for pushing the sliding limiting block to disengage from the guide positioning rod.

[0020] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0021] 1. In this utility model, a bearing positioning platform is used to position the heat sink module below the snap ring assembly mechanism. The snap ring assembly mechanism descends and presses against the heat sink module. Multiple first cylinders push the material plate to simultaneously snap multiple snap rings onto the heat sink module, completing the assembly of the heat sink module.

[0022] 2. In this utility model, a locking device is installed on the support base to lock and receive the lifting platform after it rises into position. This ensures that when the retaining spring assembly mechanism descends and presses against the radiator module, the force is borne by the locking device, preventing the downward pressure of the retaining spring assembly mechanism from directly acting on the third and fourth cylinders. This not only improves the positioning accuracy of the screw but also extends the lifespan of the third and fourth cylinders, preventing a decrease in accuracy due to excessive pressure. Secondly, a lifting rod frame is installed on the support base, and the fifth cylinder drives the lifting rod frame to move independently, achieving independent positioning of the screw. This ensures that when the retaining spring assembly mechanism presses against the radiator module, the screw remains stationary, ensuring that the locking groove on the screw is at the same level as the retaining spring.

[0033] The present invention will be further described below with reference to specific embodiments and accompanying drawings.
[0034] See Figures 1 to 10As shown, a radiator mounting mechanism includes: a support positioning platform 1 for positioning radiator module A and a snap ring assembly mechanism 2 for mounting snap rings B. The snap ring assembly mechanism 2 includes a first support frame 21, a lifting seat 22 disposed on the first support frame 21 and suspended above the support positioning platform 1, at least one base plate 23 horizontally disposed on the lifting seat 22, a stacking plate 24 vertically disposed on the lifting seat 22 for stacking snap rings B, a pusher plate 25 slidably disposed on the base plate 23 for pushing the snap rings B at the lower end of the stacking plate 24, a first cylinder 26 disposed at one end of the base plate 23 for driving the pusher plate 25 to work, and a second cylinder 27 disposed on the first support frame 21 for driving the lifting seat 22 to move. The heat sink module A is positioned below the snap ring assembly mechanism 2 using a bearing positioning platform 1. The snap ring assembly mechanism 2 descends and presses against the heat sink module A. Multiple first cylinders 26 push the material pusher 25 to simultaneously snap multiple snap rings B onto the heat sink module A, completing the assembly of the heat sink module A. The assembly efficiency is high, and only manual stacking of snap rings B onto the stacking stand 24 is required, which greatly reduces labor intensity and effectively controls costs.
[0035] The stacking plate 24 is located at the other end of the base plate 23, and the base plate 23 is provided with a first discharge hole 231 for the snap ring B to pass through and contact the pusher plate 25. The stacking plate 24 is provided with a first T-shaped guide strip 241 for positioning and stacking the snap ring B, and the base plate 23 is also provided with a second T-shaped guide strip 232 that connects to the first T-shaped guide strip 241 and extends into the first discharge hole 231. By providing the first T-shaped guide strip 241 and the second T-shaped guide strip 232 on the stacking plate 24 and the base plate 23 respectively, which can connect and stack the snap ring B, the first T-shaped guide strip 241 is used to realize the stacking and storage of the snap ring B, the snap ring B is automatically lowered by its own weight to realize feeding, and the second T-shaped guide strip 232 is used to transfer the snap ring B to the front end of the pusher plate 25 to achieve precise feeding.
[0036] The front end of the pusher plate 25 is provided with a C-shaped groove 251 for positioning the retaining ring B, and the C-shaped groove 251 is formed with a corresponding slot 252 for the screw A1; the lower end of the base plate 23 is provided with a first sliding groove 233 for positioning the pusher plate 25 to slide. By providing a C-shaped groove 251 at the front end of the pusher plate 25 to receive the retaining ring B, the C-shaped groove 251 can accommodate one retaining ring B at a time, so that when the first cylinder 26 drives the pusher plate 25 to move forward, it can push out the retaining ring B at the bottom of the second T-shaped guide strip 232 and block the stacked retaining rings B above from falling down, thereby realizing the sequential loading and fastening of retaining rings B.
[0037] The first T-shaped guide bar 241 is also equipped with a counterweight 28 for pressing against the retaining rings B to push the retaining rings B to automatically feed them. By mounting the counterweight 28 on the first T-shaped guide bar 241, the counterweight 28 presses against the stacked retaining rings B, so that the retaining rings B can maintain a sufficient downward force, ensuring that the retaining rings B are automatically discharged downward one by one without getting stuck.
[0038] The counterweight 28 is T-shaped so that its lower end can extend into the first feeding hole 231 to maintain pressure on the retaining spring B during feeding, and its upper end can be positioned on the substrate 23. By setting the counterweight 28 to a T-shape, the counterweight 28 can not only extend into the first feeding hole 231 to maintain continuous pressure on the retaining spring B, but its upper part can also be positioned on the substrate 23 to prevent the counterweight 28 from falling directly out of the first feeding hole 231.
[0039] One end of the base plate 23 is provided with a first support plate 230 for mounting the first cylinder 26. The first support plate 230 confines the pusher plate 25 within the first slide groove 233. The base plate 23 is provided with a detection device 29 for detecting the remaining amount of the retaining spring B on the stacking plate 24. By setting the detection device 29 on the base plate 23, the detection device 29 can determine whether there is sufficient remaining amount of retaining spring B. When the detection device 29 detects that the retaining spring B on the stacking plate 25 is insufficient, it can promptly remind the worker or stop the machine with an alarm.
[0040] The first support frame 21 is also vertically provided with two first guide rods 211 for guiding the movement and positioning of the lifting seat 22, and the first support frame 21 is provided with at least two first guide seats 212 that are spaced apart to position the first guide rods 211; the second cylinder 27 is connected to the lifting seat 22 by a first connecting rod 271.
[0041] The lifting base 22 is provided with four stacking uprights 24, which are arranged circumferentially around the periphery of the lifting base 22. The base plate 23, stacking uprights 24, pusher plates 25, and first cylinders 26 are correspondingly arranged in four numbers. In this embodiment, four stacking uprights 24, the same number as the screws A1 on the radiator module A, are used for synchronous material feeding. The four first cylinders 26 synchronously drive the four pusher plates 25 to achieve synchronous and rapid assembly of the four retaining rings B, thereby significantly saving time and improving efficiency.
[0042] The bearing positioning platform 1 includes a support base 11, a lifting platform 12 floating on the support base 11, a positioning fixture 13 on the lifting platform 12 for positioning the radiator module A, a third cylinder 14 and a fourth cylinder 15 located below the lifting platform 12 for pushing its lifting movement, a lifting rod frame 16 located below the lifting platform 12 and capable of penetrating the lifting platform 12 to push out the screw A1, a fifth cylinder 17 located on the support base 11 for pushing the lifting rod frame 16, at least two locking devices 18 located on the support base 11 for locking and supporting the lifting platform 12 to withstand pressure, and a drive block 19 that moves synchronously with the third cylinder 14 and the fourth cylinder 15 to push the locking devices 18 to lock the raised lifting platform 12. A locking device 18 is installed on the support base 11 to lock and receive the rising platform 12 when it is in position. This ensures that when the retaining spring assembly mechanism 2 descends and presses against the radiator module A, the force is borne by the locking device 18, preventing the downward pressure of the retaining spring assembly mechanism 2 from directly acting on the third cylinder 14 and the fourth cylinder 15. This not only improves the positioning accuracy of the screw A1 but also extends the lifespan of the third cylinder 14 and the fourth cylinder 15, preventing a decrease in accuracy due to excessive pressure. Secondly, a lifting rod frame 16 is installed on the support base 11, and the fifth cylinder 17 drives the lifting rod frame 16 to move independently, achieving independent positioning of the screw A1. This ensures that when the retaining spring assembly mechanism 2 presses against the radiator module A, the screw A1 remains stationary, ensuring that the retaining groove on the screw A1 is at the same level as the retaining spring B.
[0043] Multiple guide positioning rods 121 are provided below the lifting platform 12. The locking device 18 includes a limiting base 181 sleeved on the guide positioning rod 121, a sliding limiting block 182 slidably disposed on the limiting base 181, and a locking spring 183 disposed on the limiting base 181 and used to push the sliding limiting block 182 away from the guide positioning rod 121. The guide positioning rod 121 is provided with a limiting groove 121A for the sliding limiting block 182 to be engaged and locked. The driving block 19 is located on one side of the sliding limiting block 182 and can push the sliding limiting block 182 into the limiting groove 121A after it rises with the third cylinder 14 and the fourth cylinder 15. Multiple guide positioning rods 121 are installed below the lifting platform 12, passing through the locking device 18. The driving block 19 applies force and releases force to the locking device 18 as the third cylinder 14 and the fourth cylinder 15 move. When the driving block 19 rises, it can simultaneously drive the sliding limit block 182 to insert into the limit groove 121A of the guide positioning rod 121, so as to support the lifting platform 12. When the driving block 19 falls, the locking spring 183 pushes the sliding limit block 182 out of the limit groove 121A, so that the lifting platform 12 can fall accordingly.
[0044] One end of the sliding limit block 182 is provided with a guide wheel 182A for contacting the drive block 19, and the other end of the sliding limit block 182 is provided with a U-shaped slot 182B for fastening into the limit groove 121A; the drive block 19 is used to connect the third cylinder 14 and the lifting platform 12, and the drive block 19 is provided with a first floating spring 191 that presses against the bottom of the lifting platform 12, and the side wall of the drive block 19 is provided with a guide inclined surface 192 for contacting the guide wheel 182A. A first floating spring 191 is fitted onto the drive block 19. After the third cylinder 14 and the fourth cylinder 15 push the lifting platform 12 into position, the first floating spring 191 can continue to push the drive block 19 to rise, thereby pushing the sliding limit block 182 of the locking device 18 into the limiting groove 121A. When the third cylinder 14 and the fourth cylinder 15 pull the drive block 19 down to return to its original position, the action on the sliding limit block 182 must be released first so that the locking spring 183 can push the sliding limit block 182 out of the limiting groove 121A, thereby realizing the descent of the lifting platform 12.
[0045] The lifting rod frame 16 includes a second support plate 161 that contacts the fifth cylinder 17, multiple vertically arranged pins 162 that pass through the lifting seat 22 and press against the screw A1, a second floating spring 163 sleeved on the lower end of the pins 162, and a second guide rod 164 that is arranged on the lower end of the second support plate 161 and passes through the support base 11.
[0046] In summary, during operation, the radiator module A is transferred manually or via conveyor belt to the support positioning platform 1, which then lifts the radiator module A. As the lifting platform 12 rises, the locking device 18 locks the lifting platform 12 in place. Furthermore, the retaining spring assembly mechanism 2 descends and presses against the upper end of the radiator module A. The fifth cylinder 17 pushes the lifting rod frame 16 upward to push the upper end of the screw A1 out of the radiator module A. Then, the first cylinder 26 drives the pusher plate 25 to lock the retaining spring B onto the upper end of the screw A1, thus completing the assembly of the radiator module A.
