Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation device assembly, in particular to an aluminum substrate clamping tool and a bonding and pressing combined mechanism. Background Art

[0002] An aluminum substrate with power devices welded to it is bonded to the surface of a metal housing. The heat generated by the power devices can be transferred to the metal housing through the aluminum substrate, thereby achieving heat dissipation.

If the pressure is too high, it may cause damage to the power device. If the pressure is too low, it may cause the aluminum substrate and the metal housing to not fit tightly enough, uneven distribution of the adhesive, and reduced thermal conductivity.

DETAILED DESCRIPTION

[0037] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0039] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, the aluminum substrate clamping tooling provided by the embodiment of the present invention includes: a base 100, a first clamping arm 200, a second clamping arm 300, a first arm rod 400, a second arm rod 500 and a support arm 600; the middle part of the first clamping arm 200 and the middle part of the second clamping arm 300 are respectively hinged to the base 100, and a clamping area is formed between the first clamping arm 200 and the second clamping arm 300; the first arm rod 400 is hinged to the first clamping arm 200, and the second arm rod 500 is hinged to the second clamping arm 300; both ends of the support arm 600 are respectively provided with threads of opposite rotation directions, the first arm rod 400 is threadedly engaged with one end of the support arm 600, and the second arm rod 500 is threadedly engaged with the other end of the support arm 600.

[0041] When the support arm 600 is rotated, the first arm 400 and the second arm 500 can be adjusted toward or away from each other, thereby adjusting the overall length of the first arm 400, the support arm 600, and the second arm 500. By driving the first clamping arm 200 to swing relative to the base 100 through the first arm 400, and driving the second clamping arm 300 to swing relative to the base 100 through the second arm 500, the clamping force applied by the first and second clamping arms in the clamping area can be maintained consistent. The clamping force can also be adjusted by rotating the support arm 600, making it easy to ensure consistent clamping force during multiple clamping operations. This is particularly suitable for clamping aluminum substrates 800 and achieving uniform adhesive filling between the aluminum substrate 800 and the metal housing 700 under high temperature conditions.

[0042] In the embodiment of the present invention, the support arm 600 includes a double-threaded sleeve 610 ; the first arm 400 is fitted to one end of the double-threaded sleeve 610 , and the second arm 500 is fitted to the other end of the double-threaded sleeve 610 .

[0043] In an optional embodiment, the support arm 600 may also adopt a double-headed screw, and the threads at both ends of the double-headed screw have opposite rotation directions, one end of the double-headed screw is matched with the first arm 400, and the other end is matched with the second arm 500.

[0044] In addition, the support arm 600 also includes a rocker arm 620; the rocker arm 620 is perpendicular to the double-headed threaded sleeve 610, and the rocker arm 620 is inserted into the double-headed threaded sleeve 610. By pulling the rocker arm 620, the double-headed threaded sleeve 610 can be driven to rotate more effortlessly, thereby adjusting the clamping force of the first clamping arm 200 and the second clamping arm 300.

[0045] Furthermore, the end of the pendulum rod 620 is connected to a handle 630, which can be configured as a ball head or other shape structure that is easy to hold. When the pendulum rod 620 is inserted into the double-headed threaded sleeve 610, the handle 630 exceeds the radial dimension of the pendulum rod 620, so the handle 630 can serve as a limiting structure at the end of the pendulum rod 620, thereby preventing the pendulum rod 620 from slipping relative to the double-headed threaded sleeve 610.

[0046] like Figure 1 As shown, the first clamping arm 200 includes a first connecting rod 210 and a first clamping piece 220 connected to the first connecting rod 210; the second clamping arm 300 includes a second connecting rod 310 and a second clamping piece 320 connected to the second connecting rod 310. The middle portions of the first connecting rod 210 and the middle portions of the second connecting rod 310 are hinged to the base 100, respectively, and a clamping area is formed between the first clamping piece 220 and the second clamping piece 320. The end of the first connecting rod 210 away from the first clamping piece 220 is hinged to the first arm 400, and the end of the second connecting rod 310 away from the second clamping piece 320 is hinged to the second arm 500. The clamped component is located between the first clamping piece 220 and the second clamping piece 320. The first clamping piece 220 and the second clamping piece 320 can be configured with a wear-resistant material or an elastic, shock-absorbing material, and can form a large contact area with the clamped component to avoid uneven pressure distribution caused by localized pressure.

[0047] like Figure 1 、 Figure 3 and Figure 4 As shown, the first connecting rod 210 is detachably connected to the first clamping piece 220, and the second connecting rod 310 is detachably connected to the second clamping piece 320. The first clamping piece 220 and the second clamping piece 320 are detachably connected by means of snap fasteners or bolts. The first clamping piece 220 and the second clamping piece 320 can be replaced with different thicknesses depending on the size of the power device 900. The goal is to ensure that a predetermined clamping degree is achieved when the first clamping piece 220 and the second clamping piece 320 are parallel. This ensures that the aluminum substrate 800 on both sides of the metal housing 700 is subjected to a balanced clamping force and is tightly attached to the metal housing 700.

[0048] like Figure 1 and Figure 4As shown, the base 100 includes: a substrate 110, a first support seat 120 and a second support seat 130; the first support seat 120 and the second support seat 130 are arranged at intervals and are respectively connected to the substrate 110; the middle part of the first clamping arm 200 is hinged to the first support seat 120, and the middle part of the second clamping arm 300 is hinged to the second support seat 130.

[0049] In an optional embodiment, the substrate 110, the first support seat 120 and the second support seat 130 can be configured as an integrated structure, or the substrate 110, the first support seat 120 and the second support seat 130 can be processed separately, and then the first support seat 120 and the second support seat 130 are respectively connected to the substrate 110 by bolts.

[0050] Furthermore, the first support seat 120 is located between the first arm 400 and the clamping area, and the second support seat 130 is located between the second arm 500 and the clamping area; from one end of the connecting substrate 110 to one end connected to the first clamping arm 200, the first support seat 120 is inclined toward the direction approaching the first arm 400; from one end of the connecting substrate 110 to one end connected to the second clamping arm 300, the second support seat 130 is inclined toward the direction approaching the second arm 500. In other words, the distance from the hinge axis of the first support seat 120 and the first connecting rod 210 to the hinge of the first connecting rod 210 and the first arm 400 is smaller than the distance from the hinge axis of the first support seat 120 and the first connecting rod 210 to the first clamping plate 220. The first arm 400 drives the first connecting rod 210 to swing relative to the first support seat 120. According to the lever principle, pressure amplification can be achieved at the first clamping plate 220. The second clamping arm 300 has the same transmission principle as the first clamping arm 200, and has the function of generating a larger clamping force when the torque input of the support arm 600 is small, and can rely on the self-locking of the threaded pair to achieve locking of the clamping force.

[0051] like Figure 3 and Figure 4 As shown, the bonding and pressing combination mechanism provided by the embodiment of the present invention includes: a metal shell 700, an aluminum substrate 800 and the aluminum substrate clamping tooling described in the above embodiment; the metal shell 700 has a first end face 701 and a second end face 702 facing away from the first end face 701; at least one of the first end face 701 and the second end face 702 is bonded with the aluminum substrate 800, and the first clamping arm 200 and the second clamping arm 300 are respectively arranged opposite to the first end face 701 and the second end face 702 to press the aluminum substrate 800 to fit the metal shell 700.

[0052] Specifically, a thermally conductive adhesive can be filled between the aluminum substrate 800 and the metal shell 700. After the aluminum substrate clamping tool is clamped, the bonding and pressing assembly mechanism is placed under high temperature conditions. The adhesive is filled between the aluminum substrate 800 and the metal shell 700 and pressed tightly together. The adhesive is cured under high temperature conditions, thereby achieving bonding between the aluminum substrate 800 and the metal shell 700.

[0053] like Figure 3 、 Figure 4 and Figure 5 As shown in the embodiment of the present invention, the surface of the aluminum substrate 800 facing away from the metal shell 700 is connected to a power device 900. A plurality of power devices 900 can be provided, and power devices 900 of different sizes can be selected, and the plurality of power devices 900 can be distributed at intervals. Figure 1 and Figure 3 The first clamping piece 220 and the second clamping piece 320 of corresponding sizes can be selected according to the distribution position of the power devices 900. The first clamping piece 220 and the second clamping piece 320 each press a plurality of power devices 900, and the pressure is transmitted to the aluminum substrate 800 by the plurality of power devices 900, which can prevent a single power device 900 from being damaged by excessive pressure.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
