[0002] With the continuous development of electronic devices, the requirements for heat dissipation performance are also increasing. As a key heat dissipation component in electronic equipment, the production quality and stability of the heat sink are directly related to the overall performance and reliability of the equipment. In the heat sink production process, welding is a crucial step. It not only affects the heat transfer efficiency of the heat sink, but also has a direct impact on the overall structural strength and durability of the heat sink.

[0003] Before soldering the radiator, the various components of the radiator are usually placed in the placement table of the jig in turn, and the sides of the various components of the radiator are positioned by the bosses on the jig to align the various components of the radiator. The pressure plate is then fixedly connected to the top of the placement table, and the various components of the radiator are pressed tightly into the placement table. Finally, the placement table is taken out of the jig and transferred to the soldering furnace to achieve the soldering of the radiator. However, there is a certain gap between the bosses on the above-mentioned jig and the sides of the various components of the radiator, which makes it impossible to completely align the sides of the various components of the radiator, resulting in slight misalignment of the various components of the radiator in the horizontal direction, affecting the soldering quality of the radiator.

[0030] In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] In one embodiment of the present invention, Figure 1-5 As shown, a clamping fixture for a radiator is provided, including a base 10, a placement table 20 and a clamping mechanism. A placement groove 11 is provided in the center of the base 10. The placement table 20 is provided in the placement groove 11, and is used to place the various components of the radiator. A pressure plate 21 for pressing the various components of the radiator is detachably connected to the placement table 20. The clamping mechanism includes a first clamping module 30 and a second clamping module 40. The first clamping module 30 is provided on the base 10 along the X-axis direction, and is used for clamping and aligning the various components of the radiator on both sides of the X-axis. The second clamping module 40 is provided on the base 10 along the Y-axis direction, and is used for clamping and aligning the various components of the radiator on both sides of the Y-axis.

[0032] By setting the first clamping module 30 and the second clamping module 40, the first clamping module 30 and the second clamping module 40 clamp the various components of the radiator on both sides of the X-axis and the Y-axis respectively, so that the various components of the radiator are aligned with each other in the horizontal direction, avoiding slight misalignment between the various components of the radiator, and after the first clamping module 30 and the second clamping module 40 clamp the various components of the radiator, the pressure plate 21 is fixed above the placement table 20, and the pressure plate 21 applies a downward pressing force to the various components of the radiator, so that the various components of the radiator are tightly fitted, further locking the relative positions of the various components of the radiator to prevent misalignment between the various components of the radiator.

[0033] Preferably, the first clamping module 30 includes two sets of first clamping actuators 31. The first clamping actuators 31 are pneumatic cylinders, and the two sets of first clamping actuators 31 are symmetrically distributed along the X-axis on the base 10. The two sets of first clamping actuators 31 are located on either side of the placement table 20 in the X-axis direction. The first clamping actuators 31 are provided with first clamping plates 32. When the first clamping actuators 31 are activated, they drive the first clamping plates 32 toward the placement table 20. The first clamping plates 32 on both sides clamp the radiator components on both sides of the X-axis, so that the radiator components are aligned with each other on both sides of the X-axis.

[0034] Specifically, the second clamping module 40 includes two sets of second clamping actuators 41. The two sets of second clamping actuators 41 are symmetrically distributed along the Y-axis on the base 10 and are located on either side of the placement table 20 in the Y-axis direction. The second clamping actuators 41 are provided with second clamping plates 42. When the second clamping actuators 41 are activated, they drive the second clamping plates 42 toward the placement table 20. The second clamping plates 42 on both sides clamp the radiator components on both sides of the Y-axis, ensuring that the radiator components are aligned with each other on both sides of the Y-axis.

[0035] Furthermore, the first clamping module 30 and the second clamping module 40 are arranged vertically. By arranging the first clamping module 30 and the second clamping module 40 vertically, the sides of the radiator components can be aligned with each other in the horizontal direction, avoiding misalignment between the radiator components and improving the welding effect of the radiator.

[0036] Preferably, four sets of circumferentially distributed connecting posts 22 are provided between the placement platform 20 and the pressure plate 21. Locking screws 23 are located at the tops of the connecting posts 22, which are detachably connected to the pressure plate 21. The detachable connection between the locking screws 23 and the pressure plate 21 improves the flexibility of the pressure plate 21, facilitating quick removal of the three heat sinks from the top of the placement platform 20 after welding, thus increasing the speed of heat sink removal.

[0037] Furthermore, the pressure plate 21 is provided with a first connection hole 211 and a second connection hole 212. The first connection holes 211 and the second connection holes 212 are evenly spaced along the Y-axis. By providing the first connection holes 211 and the second connection holes 212, after the radiator components are horizontally positioned, they are locked with the locking screws 23 in the first connection holes 211 and the second connection holes 212, respectively, so that the pressure plate 21 presses the radiator components against the placement table 20, further locking the relative positions of the radiator components.

[0038] Furthermore, the first connecting holes 211 and the second connecting holes 212 are provided in two groups, and the two groups of first connecting holes 211 and the two groups of second connecting holes 212 are evenly spaced along the X-axis direction on the pressure plate 21. A first slide groove 213 is provided at one end of the first connecting hole 211, and the first slide groove 213 is slidably connected to the locking screw 23. A second slide groove 314 is provided at one end of the second connecting hole 212, and the second slide groove 314 is slidably connected to the locking screw 23. By providing the first slide groove 213 and the second slide groove 314, the locking screw 23 can be flexibly moved between the first slide groove 213 and the first connecting hole 211, and between the second slide groove 314 and the second connecting hole 212, thereby achieving rapid fixing and removal of the pressure plate 21 and simplifying the installation and removal steps of the pressure plate 21.

[0039] Preferably, the placement platform 20 is provided with multiple sets of regularly or irregularly distributed first through-holes 24. The pressure plate 21 is provided with multiple sets of regularly or irregularly distributed second through-holes 25. The placement platform 20 is provided with four sets of circumferentially distributed positioning pins 26. The placement platform 20 is also provided with four sets of recessed access portions 201. The provision of positioning pins 26 facilitates quick positioning of the placement platform 20 with components at the bottom of the radiator, simplifying the positioning process. The provision of access portions 201 also facilitates access to the radiator by the operator, increasing the speed of radiator removal.

[0040] In this embodiment, four groups of handles are provided on the base 10 at equal intervals, which make it easier for workers to take the clamping device, thereby improving the convenience of using the clamping device.
