Description

Technical Field

[0001] The present application belongs to the technical field of cutting heat sink material products, and in particular, relates to a fixture for slicing heat sink material products. Background Art

[0002] Heat sink materials generally refer to materials used to absorb, conduct and disperse heat. In many fields, such as electronic equipment, optoelectronic devices, and the automotive industry, heat dissipation is very important. Heat sink materials are designed to help effectively handle heat in the device to prevent overheating and maintain stable performance of the device.

[0003] Heat sink materials usually have high thermal conductivity in order to transfer heat from the heat source (such as electronic components) to the heat sink or environment. Common heat sink materials include aluminum, copper, metal alloys, ceramics and some special composite materials. The selection of appropriate heat sink materials depends on the requirements of the application, such as the required thermal conductivity, weight, cost and corrosion resistance.

[0004] At present, the heat sink materials used in electronic packaging are often processed by methods such as wire cutting and CNC milling. However, the above two methods have low processing efficiency and high cost. In the face of the current competition in cost and efficiency, manual or automatic saw blade machines are generally used for cutting and processing the shape. However, the fixture currently used for cutting by saw blade machines simply uses a modified vise to stack and clamp multiple heat sink materials. During cutting, the stacked heat sink materials are easily misaligned due to unstable clamping, resulting in uneven sizes of the heat sink materials after cutting. In addition, the use of a modified vise for clamping will interfere with the cutting process, and the clamped part of the heat sink material may not be cut in place. Utility Model Content

[0040] The fixture for slicing heat sink material products provided in the present application is exemplarily described below in conjunction with specific embodiments.

[0041] like Figure 1 and Figure 2As shown, the clamp for slicing heat sink material products provided in the embodiment of the present application includes a clamp seat 1 and a pressure cover 2; a placement groove 11 extending along a first direction is provided on the clamp seat 1, and a plurality of cutting grooves 12 penetrating the groove walls are arranged at intervals along the first direction on the groove walls on both sides of the placement groove 11, and the cutting grooves 12 on the two groove walls are arranged one by one in the second direction, and the second direction intersects with the first direction; the pressure cover 2 is covered on the clamp seat 1 and covers the opening of the placement groove 11, and the pressure cover 2 is used to press the heat sink material products 100 stacked in the placement groove 11, and a plurality of avoidance holes 21 for avoiding the cutting grooves 12 are arranged at intervals along the first direction on the pressure cover 2.

[0042] In this embodiment, the heat sink material products 100 can be stacked one by one in the placement groove 11, and then the pressure cover 2 is placed on the fixture seat 1 and covers the opening of the placement groove 11 to compress the heat sink material products 100 stacked in the placement groove 11. The multiple avoidance holes 21 set on the pressure cover 2 can correspond to each cutting groove 12 in the cutting direction of the cutting machine. During cutting, the blade of the cutting machine can enter through one of the avoidance holes 21 and cut the stacked heat sink material products 100 in the placement groove 11 one by one along the corresponding group of cutting grooves 12. The blade of the cutting machine enters along the avoidance holes 21 on the pressure cover 2 in sequence to complete the overall cutting of the heat sink material products 100 in the placement groove 11 into blocks.

[0043] The fixture for slicing heat sink material products provided in the present application can stably clamp the heat sink material through the placement groove 11 and the pressure cover 2 during cutting, avoiding misalignment during the cutting process, so that the size of the block heat sink material product 100 formed along the cutting direction is consistent. At the same time, it will not interfere with the work of the cutting machine, and the clamped part of the heat sink material can also be cut in place to avoid waste.

[0044] Among them, for the multiple cutting grooves 12 spaced apart along the first direction on the groove wall, two adjacent cutting grooves 12 are grouped together, and the spacing between each group of cutting grooves 12 can be equal, so that the size of the block heat sink material product 100 cut by the fixture is consistent to meet the needs of batch processing. Of course, according to actual processing requirements, each group of cutting grooves 12 can be set to have different spacings to meet the needs of diversified sizes of the block heat sink material product 100.

[0045] like Figure 1 As shown, for ease of understanding, an XY plane coordinate system is established, wherein the direction indicated by the X axis is the first direction, and the direction indicated by the Y axis is the second direction. The angle between the first direction and the second direction can be adjusted according to the shape of the heat sink material product 100. For shapes such as rectangles and squares, such as Figure 1As shown, the first direction and the second direction may be perpendicular to each other, and the angle between the first direction and the second direction is 90°. For shapes such as parallelograms, the angle formed by the intersection of the first direction and the second direction is an acute angle.

[0046] In the prior art, a modified vise is generally used for single-row stacking clamping, and only one row can be cut each time, resulting in low processing efficiency.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment, a plurality of placement grooves 11 are provided, and the plurality of placement grooves 11 are arranged side by side and at intervals on the fixture seat 1 along the second direction, and the cutting grooves 12 on the groove walls of two adjacent placement grooves 11 are arranged one by one in the second direction.

[0048] Through the above-mentioned structural setting, by providing a plurality of placement grooves 11 on the clamp seat 1, the clamp for slicing heat sink material products can accommodate more heat sink material products 100, and can perform multiple rows of cutting simultaneously, thereby improving the overall cutting efficiency.

[0049] like Figure 1 As shown, in one embodiment, a boss 13 is provided on the fixture seat 1, and the placement groove 11 is provided on the boss 13, so that the placement groove 11 protrudes from the surface of the fixture seat 1 in the cutting direction of the cutting machine.

[0050] In the above embodiment, the placement groove 11 is lifted up as a whole by the boss 13 so that the placement groove 11 protrudes from the surface of the clamp seat 1 in the cutting direction of the cutting machine, which is convenient for positioning the blade of the cutting machine; at the same time, it can avoid the collision between the blade of the cutting machine and the clamp seat 1, so as to protect the cutting machine.

[0051] like Figure 1 and Figure 3 As shown, in a specific embodiment, the pressure cover 2 is an arched structure, so that the pressure cover 2 can fully cover the placement groove 11 arranged on the boss 13.

[0052] Specifically, Figure 3 As shown, the gland 2 includes a first bottom plate 22, a first side plate 23, a top plate 24, a second side plate 25 and a second bottom plate 26 connected in sequence to form an arch structure. The structure formed by the first side plate 23, the top plate 24 and the second side plate 25 covers the boss 13 and the placement groove 11, and the avoidance hole 21 is arranged between the first side plate 23, the top plate 24 and the second side plate 25. The gland 2 can be fixed on the fixture seat 1 through the first bottom plate 22 and the second bottom plate 26.

[0053] like Figure 2 As shown, in one embodiment, the depth of the cutting groove 12 is greater than the depth of the placement groove 11 .

[0054] The above-mentioned structural arrangement ensures that the heat sink material product 100 located at the bottom of the placement groove 11 can be cut in place by the blade of the cutting machine to avoid omission.

[0055] like Figure 1 As shown, in one embodiment, a fastening structure 3 is provided between the clamp seat 1 and the pressure cover 2 .

[0056] The fastening structure 3 is used to realize a detachable connection between the pressure cover 2 and the clamp seat 1, thereby facilitating the loading of the heat sink material product 100 and the unloading of the cut block heat sink material product 100.

[0057] like Figure 1 , Figure 2 and Figure 3 As shown, in a specific embodiment, the fastening structure 3 includes a bolt 31 and a threaded hole 32 arranged on the clamp seat 1 and screwed to the bolt 31, and a through hole 33 corresponding to the threaded hole 32 is arranged on the pressure cover 2. The bolt 31 can pass through the through hole 33 and be screwed to the threaded hole 32 to limit the pressure cover 2 on the clamp seat 1.

[0058] By setting the above structure, the gland 2 can be restricted on the clamp seat 1 or the restriction on the gland 2 can be released only by rotating the bolt 31 .

[0059] like Figure 1 and Figure 2 As shown, in one embodiment, both ends of the placement slot 11 extending along the first direction are set as openings, and a limiting plate 4 is set on one side of the clamp seat 1, and the limiting plate 4 covers one of the openings.

[0060] Through the arrangement of the above structure, the heat sink material product 100 can enter the placement groove 11 from the opening where the limiting plate 4 is not set, be stacked together in the placement groove 11, and be limited by the limiting plate 4 at another opening. At the same time, it is also convenient to unload the block-shaped heat sink material product 100 formed after cutting from the opening where the limiting plate 4 is not set, without the need to flip the clamp seat 1 or clamp it out of the placement groove 11 through a clamping member and other complicated processes. In addition, the arrangement of the above structure can also facilitate the placement of some heat sink material products 100 whose length is greater than the length of the placement groove 11 extending along the first direction, so as to achieve the cutting of diversified heat sink material products 100.

[0061] like Figure 2 As shown, preferably, the limiting plate 4 is detachably connected to the fixture seat 1 to facilitate the loading of the heat sink material product 100 before cutting and the unloading of the block-shaped heat sink material product 100 after cutting.

[0062] like Figure 2 As shown, specifically, the limiting plate 4 is a T-shaped plate to correspond to the boss 13 provided on the fixture seat 1 .

[0063] Specifically, Figure 2 As shown, the limiting plate 4 and the fixture seat 1 can also adopt the fastening structure 3 in the above embodiment, and the principle is the same, which will not be further described.

[0064] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, a positioning hole 27 is provided on the pressure cover 2 , and a positioning column 14 corresponding to the positioning hole 27 is provided on the clamp seat 1 .

[0065] With the above-mentioned structure, when the gland 2 is installed, the plurality of avoidance holes 21 on the gland 2 can be aligned one by one with the cutting grooves 12 on the groove wall of the placement groove 11 through the positioning columns 14 and the positioning holes 27 .

[0066] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
