Description

Technical Field

[0001] This disclosure relates to the technical field of radiator manufacturing, and in particular to a radiator pressing mechanism and a radiator assembly fixture. Background Technology

[0002] To achieve better heat dissipation, heat sinks typically have grooves to house heat pipes. However, after installation, the heat pipes are often uneven, making assembly difficult. Therefore, the installed heat pipes must be smoothed out. Please refer to [link / reference]. Figure 1 Currently, most manufacturers use a roller mechanism 20 to flatten the heat pipe 102. However, because the protruding part of the heat pipe 102 before flattening is an arc-shaped surface, the roller mechanism 20 is prone to slipping on the heat pipe 102 due to its structural design, which increases the difficulty of controlling the roller mechanism 20. At the same time, Figure 1 The middle roller mechanism 20 can only press a single heat pipe 102 at a time, resulting in low production efficiency and high production costs. Utility Model Content

[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a radiator pressing mechanism and radiator assembly fixture that can be smoothly controlled.

[0004] The purpose of this disclosure is achieved through the following technical solution:

[0005] A radiator tube pressing mechanism includes a mounting bracket;

[0006] The mounting bracket is used to mount the CNC machine tool and is located above the worktable of the CNC machine tool; the mounting bracket is used to connect to the drive device of the CNC machine tool, and the worktable is used to place the heat sink;

[0007] The radiator pressing mechanism also includes heat pipe rollers;

[0008] The heat pipe roller is rotatably mounted on the mounting bracket and positioned close to the worktable. A first pressing section, a second pressing section, and a guide groove are formed on the surface of the heat pipe roller. The guide groove is located between the first pressing section and the second pressing section. The first pressing section is used to slide against one heat pipe mounted on the radiator, and the second pressing section is used to slide against another heat pipe mounted on the radiator. The guide groove corresponds to the partition area formed between the two heat pipes on the radiator. The edge of the guide groove slides against the side edge of the partition area to allow the heat pipe roller to move in a specific direction.

[0009] In some embodiments, the first side edge of the guide groove opening is opposite to the second side edge of the guide groove opening, and the distance between the first side edge of the guide groove opening and the second side edge of the guide groove opening is equal to the width of the partition area; the first side edge of the guide groove opening slides against the first side edge of the partition area, and the second side edge of the guide groove opening slides against the second side edge of the partition area.

[0010] In some embodiments, the mounting bracket includes a connected transmission rod and a mounting base. The transmission rod is used to mount on a CNC machine tool, and the mounting base has a rotating groove. The heat pipe roller is rotatably mounted in the rotating groove, and the wheel surface of the heat pipe roller extends out of the groove opening.

[0011] In some embodiments, the heat pipe roller includes an outer wheel body, an inner pressure core, and a shaft; the shaft passes through the inner pressure core, and both ends of the shaft are rotatably connected to the groove wall of the rotating groove; the outer wheel body is sleeved outside the inner pressure core, and the outer surface of the outer wheel body forms the first pressure tube portion, the second pressure tube portion, and the guide groove.

[0012] In some embodiments, the inner pressure core includes a first side pressure core, an intermediate body, and a second side pressure core arranged sequentially; the intermediate body is in concave-convex fit with the first side pressure core and the second side pressure core respectively; the shaft rotates through the first side pressure core, the intermediate body, and the second side pressure core in sequence; the first side pressure core corresponds to the position of the first pressure tube portion, and the second side pressure core corresponds to the position of the second pressure tube portion.

[0013] In some embodiments, the mounting base has a rotating hole on each side of the heat pipe roller, and the rotating holes are connected to the rotating groove; each end of the shaft passes through one of the rotating holes and is rotatably connected to the hole wall of the corresponding rotating hole.

[0014] In some embodiments, each end of the shaft extends outward from the corresponding rotating hole and forms a mating end; a retaining ring is fitted onto each mating end, and each retaining ring slides against the mounting base.

[0015] In some embodiments, the diameter of the cross-section of the drive rod gradually increases from the end furthest from the mounting base to the end closest to the mounting base.

[0016] In some embodiments, the transmission rod and the mounting base are integrally connected.

[0017] A radiator assembly fixture includes a CNC machine tool and a radiator tube pressing mechanism according to any of the above embodiments.

[0018] Compared with the prior art, this disclosure has at least the following advantages:

[0019] The aforementioned radiator pressing mechanism, with its guide groove positioned between the first and second pressing sections, allows the first pressing section to slide against one heat pipe mounted on the radiator, and the second pressing section to slide against another heat pipe mounted on the radiator. This enables the heat pipe pressing roller to simultaneously flatten both heat pipes, improving production efficiency and reducing costs. Furthermore, because the heat pipe pressing roller contacts one heat pipe via the first pressing section and the other via the second pressing section, it provides better support. The guide groove corresponds to the partition area between the two heat pipes. By sliding the edge of the guide groove against the side edge of the partition area, the direction of the heat pipe pressing roller is restricted, guiding it to smoothly and orientably press the heat pipes.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0035] Please see Figure 2One embodiment of the radiator pressing mechanism includes a mounting bracket 100 and a heat pipe pressing roller 200. The mounting bracket 100 is used to mount a CNC machine tool (not shown) and is located above the worktable (not shown) of the CNC machine tool. The mounting bracket 100 is used to connect to the drive device (not shown) of the CNC machine tool, and the worktable is used to place the radiator 10. The heat pipe pressing roller 200 is rotatably mounted on the mounting bracket 100 and is located close to the worktable. A first pressing part 2110, a second pressing part 2120, and a guide groove are formed on the surface of the heat pipe pressing roller 200. 2130, a guide groove 2130 is disposed between the first pressing tube portion 2110 and the second pressing tube portion 2120; the first pressing tube portion 2110 is used to slide against one heat pipe installed on the radiator 10, and the second pressing tube portion 2120 is used to slide against another heat pipe installed on the radiator 10; the guide groove 2130 is used to correspond to the partition area 103 formed between the two heat pipes 102 on the radiator 10; the groove edge of the guide groove 2130 is used to slide against the side edge of the partition area 103 so that the heat pipe roller 200 moves in a directional manner.

[0036] It is understandable that, since the guide groove 2130 is located between the first pressing tube section 2110 and the second pressing tube section 2120, by having the first pressing tube section 2110 slide against one heat pipe installed on the radiator 10 and the second pressing tube section 2120 slide against another heat pipe installed on the radiator 10, the two heat pipes 102 can be flattened at the same time by the heat pipe roller 200, thereby improving production efficiency and reducing production costs. Furthermore, since the heat pipe roller 200 contacts one heat pipe through the first pressing section 2110 and another heat pipe through the second pressing section 2120, it can provide better support for the heat pipe roller 200. At this time, the guide groove 2130 can correspond to the separation area 103 formed between the two heat pipes 102. By sliding the groove edge of the guide groove 2130 against the side edge of the separation area 103, the direction of the heat pipe roller 200 can be restricted, so as to guide the heat pipe roller 200 to smoothly and orientally press the heat pipe 102.

[0037] In some embodiments, the first side edge of the opening of the guide groove 2130 is positioned opposite to the second side edge of the opening of the guide groove 2130, and the distance between the first side edge of the opening of the guide groove 2130 and the second side edge of the opening of the guide groove 2130 is equal to the width of the partition region 103; the first side edge of the opening of the guide groove 2130 slides against the first side edge of the partition region 103, and the second side edge of the opening of the guide groove 2130 slides against the second side edge of the partition region 103. It is understandable that, since the first side edge of the guide groove 2130 is opposite to the second side edge of the guide groove 2130, and the distance between the first side edge of the guide groove 2130 and the second side edge of the guide groove 2130 is equal to the width of the partition area 103, when the first side edge of the guide groove 2130 slides against the first side edge of the partition area 103, the second side edge of the guide groove 2130 slides against the second side edge of the partition area 103, so that the heat pipe roller 200 can be further restricted in its movement direction by being pressed by both the first side edge and the second side edge of the partition area 103.

[0038] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the mounting bracket 100 includes a connected transmission rod 110 and a mounting base 120. The transmission rod 110 is used for mounting on a CNC machine tool, and the mounting base 120 has a rotating groove 1210. The heat pipe roller 200 is rotatably mounted in the rotating groove 1210, with the wheel surface of the heat pipe roller 200 extending out of the groove opening. It can be understood that because the heat pipe roller 200 is rotatably mounted in the rotating groove 1210, by allowing the wheel surface of the heat pipe roller 200 to extend out of the groove opening, the wheel surface of the heat pipe roller 200 can be rolled onto the heat pipe 102. Furthermore, since the mounting base 120 is connected to the CNC machine tool via the transmission rod 110, the displacement of the heat pipe roller 200 can be controlled by the CNC machine tool.

[0039] Please refer to the following: Figure 3 and Figure 4In some embodiments, the heat pipe roller 200 includes an outer roller body 210, an inner pressure core 220, and a shaft 230. The shaft 230 passes through the inner pressure core 220, and its two ends are rotatably connected to the groove wall of the rotating groove 1210. The outer roller body 210 is sleeved outside the inner pressure core 220, and its outer surface forms a first pressure tube portion 2110, a second pressure tube portion 2120, and a guide groove 2130. It can be understood that because the shaft 230 passes through the inner pressure core 220, and its two ends are rotatably connected to the groove wall of the rotating groove 1210, the outer roller body 210 sleeved outside the inner pressure core 220 can provide roller pressure to the outer roller body 210 through the inner pressure core 220, and the first pressure tube portion 2110, the second pressure tube portion 2120, and the guide groove 2130 formed on the outer surface of the outer roller body 210 can roll the heat pipe 102.

[0040] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the inner pressure core 220 includes a first side pressure core 2210, an intermediate body 2220 and a second side pressure core 2230 arranged sequentially; the intermediate body 2220 is in concave-convex fit with the first side pressure core 2210 and the second side pressure core 2230 respectively; the shaft 230 rotates through the first side pressure core 2210, the intermediate body 2220 and the second side pressure core 2230 in sequence; the first side pressure core 2210 corresponds to the position of the first pressure tube portion 2110 and the second side pressure core 2230 corresponds to the position of the second pressure tube portion 2120. It is understandable that the inter-body 2220 can form a tight connection structure with the first side pressure core 2210 and the second side pressure core 2230 by engaging with the first side pressure core 2210 and the inter-body 2220 and the second side pressure core 2230 respectively. Since the first side pressure core 2210 corresponds to the position of the first pressure tube 2110 and the second side pressure core 2230 corresponds to the position of the second pressure tube 2120, the first side pressure core 2210 and the second side pressure core 2230 respectively provide roller pressure to the heat pipe 102.

[0041] Please see Figure 3 In some embodiments, the mounting base 120 has a rotating hole 1220 on each side of the heat pipe roller 200, and both rotating holes 1220 are connected to the rotating groove 1210; each end of the shaft 230 passes through a rotating hole 1220 and is rotatably connected to the hole wall of the corresponding rotating hole 1220. It can be understood that because each end of the shaft 230 passes through a rotating hole 1220 and is rotatably connected to the hole wall of the corresponding rotating hole 1220, each end of the shaft 230 can rotate within its respective rotating hole 1220, so that the heat pipe roller 200 can more smoothly roll the heat pipe 102.

[0042] Combination Figure 3As shown, in some embodiments, each end of the shaft 230 extends outward from the corresponding rotating hole 1220 to form a mating end; a retaining ring 2310 is sleeved on each mating end, and each retaining ring 2310 slides against the mounting base 120. It can be understood that since each end of the shaft 230 extends outward from the corresponding rotating hole 1220 to form a mating end, the retaining ring 2310 sleeved on each mating end slides against the mounting base 120 to prevent the shaft 230 from dislodging from the rotating hole 1220.

[0043] Please see Figure 2 In some embodiments, the diameter of the cross-section of the drive rod 110 gradually increases from the end furthest from the mounting base 120 to the end closest to the mounting base 120. It can be understood that because the diameter of the cross-section of the drive rod 110 gradually increases from the end furthest from the mounting base 120 to the end closest to the mounting base 120, the diameter of the cross-section of the drive rod 110 at the position where it connects to the mounting base 120 is larger, thereby enabling better pushing of the heat pipe roller 200 to roll the heat pipe 102.

[0044] Please see Figure 3 In some embodiments, the transmission rod 110 and the mounting base 120 are integrally connected. It is understood that because the transmission rod 110 and the mounting base 120 are integrally connected, the mounting bracket 100 has higher structural strength, thus making the heat pipe roller 200 more durable after being installed on the mounting bracket 100.

[0045] Please combine Figure 1 As shown, this disclosure also provides a radiator 10 assembly fixture, including a CNC machine tool and a radiator pressing mechanism of any of the above embodiments. It can be understood that by applying the radiator pressing mechanism of this disclosure to the radiator 10 assembly fixture, since the guide groove 2130 is disposed between the first pressing part 2110 and the second pressing part 2120, by having the first pressing part 2110 slide against one heat pipe 102 mounted on the radiator 10, and the second pressing part 2120 slide against another heat pipe 102 mounted on the radiator 10, the heat pipe pressing roller 200 can simultaneously flatten both heat pipes 102, thereby improving production efficiency and reducing production costs. Furthermore, since the heat pipe roller 200 contacts one heat pipe 102 through the first pressing part 2110 and another heat pipe 102 through the second pressing part 2120, it can provide better support for the heat pipe roller 200. At this time, the guide groove 2130 can correspond to the separation area 103 formed between the two heat pipes 102. By sliding the groove edge of the guide groove 2130 against the side edge of the separation area 103, the direction of the heat pipe roller 200 can be restricted, so as to guide the heat pipe roller 200 to smoothly and orientally press the heat pipe 102.

[0046] Compared with the prior art, this disclosure has at least the following advantages:

[0047] The aforementioned radiator pressing mechanism, with the guide groove 2130 located between the first pressing part 2110 and the second pressing part 2120, allows the first pressing part 2110 to slide against one heat pipe 102 mounted on the radiator 10, and the second pressing part 2120 to slide against another heat pipe 102 mounted on the radiator 10. This enables the heat pipe roller 200 to simultaneously flatten both heat pipes 102, thereby improving production efficiency and reducing production costs. Furthermore, since the heat pipe roller 200 contacts one heat pipe 102 through the first pressing part 2110 and another heat pipe 102 through the second pressing part 2120, it can provide better support for the heat pipe roller 200. At this time, the guide groove 2130 can correspond to the separation area 103 formed between the two heat pipes 102. By sliding the groove edge of the guide groove 2130 against the side edge of the separation area 103, the direction of the heat pipe roller 200 can be restricted, so as to guide the heat pipe roller 200 to smoothly and orientally press the heat pipe 102.

[0048] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
