Description

Technical Field

[0001] This utility model relates to the field of heat sink processing, and specifically to a heat sink cutting platform. Background Technology

[0002] In the field of heat sink processing, the processing of ultra-thin stainless steel heat sinks has always faced many challenges. Taking an ultra-thin stainless steel heat sink with a thickness of only 0.3mm as an example, its processing and cutting depth requires a precision of 0.179mm, making it difficult for conventional cutting methods to meet the processing requirements.

[0003] Traditional cutting methods typically involve attaching a UV film to the heatsink and then cutting it with a cutting blade. However, in practice, due to uneven UV film adhesion and stress differences during cutting, the heatsink is prone to delamination. Once delamination occurs, the heatsink cannot maintain a stable position during cutting, making it difficult to guarantee cutting accuracy. Furthermore, ultra-thin stainless steel heatsinks are inherently thin and easily deformed under cutting stress, ultimately leading to product scrap and severely impacting production efficiency and product quality. Currently, there are no high-efficiency cutting fixtures specifically designed for processing such ultra-thin, specially shaped heatsinks on the market, making the development of a new type of heatsink cutting platform urgently needed. Utility Model Content

[0004] This invention provides a heat sink cutting platform to address the problems of existing technologies.

[0005] The objective of this utility model can be achieved through the following technical solution: A heat sink cutting platform includes: a fixture base and several sets of fixture platforms. The fixture base has several sets of large vacuum adsorption through holes through its middle. The upper outer side of the fixture base is provided with positioning posts at intervals. The fixture platforms are disposed on the fixture base. The fixture platforms have several sets of small vacuum adsorption through holes through their middle. The lower outer side of the fixture platforms is provided with positioning holes for the positioning posts to be inserted. The upper outer side of the fixture platforms is provided with positioning posts at intervals. The upper part of the fixture platforms is symmetrically and at intervals with product positioning pins located outside the small vacuum adsorption through holes. Side sealing blocks are provided on the side end faces adjacent to the fixture platforms.

[0006] As a further improvement, the thickness of the side sealing block is 0.2mm to 0.3mm.

[0007] In a further improvement, the number of large vacuum adsorption through holes is set to be equal to the number of fixture platforms, and the large vacuum adsorption through holes corresponding to the lower end of each set of fixture platforms are located within the projection plane of the fixture platform.

[0008] As a further improvement, the fixture base has grooves on both the left and right sides.

[0009] In a further improvement, the interface between the large vacuum adsorption through-hole and the small vacuum adsorption through-hole is elliptical.

[0010] As a further improvement, the upper end of the first positioning post is provided with a tapered guide head, and the upper end of the second positioning post is provided with a tapered guide head.

[0011] In a further improvement, two sets of positioning pins are provided on each side of the fixture platform, and two sets of positioning posts are provided on each side of the fixture platform.

[0012] Compared with the prior art, the advantages of this utility model heat sink cutting platform are as follows:

[0013] Composed of a fixture base and several fixture platforms, it utilizes vacuum adsorption and a multi-positioning structure to ensure the stability of the heat sink during the cutting process, facilitating strong adsorption of the heat sink and solving problems such as delamination and heat sink deformation. Side sealing blocks are set on the side end faces of the fixture platforms. When the fixture platforms are installed in place and vacuum adsorption is activated, the side sealing blocks can effectively prevent outside air from entering the vacuum adsorption area, enhancing the vacuum adsorption effect and allowing the heat sink to be adsorbed more firmly. Furthermore, multiple fixture platforms can be combined and installed on a single fixture base, allowing multiple heat sink products to be neatly arranged, facilitating the simultaneous cutting of multiple heat sinks and reducing operation time.

[0020] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0021] Example 1

[0022] A heat sink cutting platform includes: a fixture base 1 and several sets of fixture platforms 2. The fixture base 1 has several sets of large vacuum adsorption through holes 11 through its middle. The upper outer side of the fixture base 1 is provided with positioning posts 12 at intervals. The fixture platforms 2 are disposed on the fixture base 1. The fixture platforms 2 have several sets of small vacuum adsorption through holes 21 through their middle. The lower outer side of the fixture platforms 2 is provided with positioning holes 22 for the positioning posts 12 to be inserted. The upper outer side of the fixture platforms 2 is provided with positioning posts 23 at intervals. The upper end of the fixture platforms 2 is symmetrically provided with product positioning pins 24 located outside the small vacuum adsorption through holes 21 at intervals. Side sealing blocks 3 are provided on the side end faces adjacent to the fixture platforms 2.

[0023] like Figures 1-4 As shown, the working principle of this utility model is as follows:

[0024] The large vacuum adsorption through-hole 11 in the middle of the fixture base 1 works in conjunction with the small vacuum adsorption through-hole 21 in the middle of the fixture platform 2. When the external vacuum equipment is turned on, gas is extracted from the large and small vacuum adsorption through-holes, creating a negative pressure environment on the surface of the fixture platform 2. At this time, the heat sink product 4 placed on the fixture platform 2 will be subject to adsorption force from below and be tightly adsorbed onto the surface of the fixture platform 2, effectively preventing displacement due to external forces during cutting.

[0025] The positioning post 12 on the outer side of the fixture base 1 cooperates with the positioning hole 22 at the lower outer side of the fixture platform 2 to achieve precise positioning and installation of the fixture platform 2 on the fixture base 1, ensuring the accuracy and consistency of the installation position of each set of fixture platforms 2. The positioning post 23 at the upper outer side of the fixture platform 2 can be used for positioning of upper fixtures or other auxiliary devices, further improving the structural construction of the entire cutting platform.

[0026] Side sealing blocks 3 are installed on the side end faces of adjacent fixture platforms 2. When fixture platforms 2 are installed in place and vacuum adsorption is activated, side sealing blocks 3 can effectively prevent outside air from entering the vacuum adsorption area, enhancing the vacuum adsorption effect and allowing the heat sink to be more firmly adsorbed. Product positioning pins 25 are used for precise positioning of the heat sink on fixture platforms 2, ensuring accurate placement of the heat sink and meeting the cutting accuracy requirements.

[0027] Through the above structural design, the heat sink cutting platform can effectively solve the problems of heat sinks being prone to delamination and deformation in traditional cutting methods, and greatly improve the stability of heat sink cutting and processing and the product qualification rate.

[0028] As a further preferred embodiment, the side seal 3 has a thickness of 0.2mm to 0.3mm. This thickness ensures that the side seal block 3 has a certain elastic deformation capacity, and during the splicing of the fixture platform 2 and the installation of the heat sink, it fits tightly against the gap, effectively preventing air leakage and enhancing the vacuum adsorption effect.

[0029] As a further preferred embodiment, the number of large vacuum adsorption through holes 11 is equal to the number of fixture platforms 2, and the large vacuum adsorption through holes 11 corresponding to the lower end of each fixture platform 2 are located within the projection plane of the fixture platform 2. This arrangement allows each fixture platform 2 to obtain an independent and matched vacuum adsorption channel. When the vacuum equipment is working, the large vacuum adsorption through holes 11 can provide sufficient and uniform negative pressure to the corresponding fixture platform 2, ensuring that the heat sink on the fixture platform 2 receives a relatively consistent adsorption force at all positions, avoiding local warping or displacement of the heat sink due to uneven adsorption force, and further improving the stability and reliability of vacuum adsorption.

[0030] As a further preferred embodiment, the jig base 1 has grooves 13 on both the left and right sides, mainly to facilitate the separation of the jig base 1 and several sets of jig platforms 2 after completion, thereby improving the ease of operation.

[0031] As a further preferred embodiment, the interfaces of the large vacuum adsorption through-hole 11 and the small vacuum adsorption through-hole 21 are both elliptical. Compared to circular through-holes, elliptical through-holes can provide a larger airflow channel along their major axis for the same area. During vacuum adsorption, the elliptical through-holes allow air to be extracted more smoothly, accelerating the airflow rate and more quickly forming a negative pressure environment on the surface of the fixture platform 2, thus improving the response speed of vacuum adsorption. At the same time, the shape of the elliptical through-holes can better adapt to the shape and placement direction of the heat sink, making the adsorption force distribution more uniform and reducing the risk of heat sink deformation caused by the adsorption force concentrating in a local area.

[0032] As a further preferred embodiment, the upper end of the first positioning post 12 is provided with a tapered guide head 121, and the upper end of the second positioning post 23 is provided with a tapered guide head 231. When installing the fixture platform 2, the tapered guide head 121 of the first positioning post 12 can play a guiding role, making it easier and more accurate to insert the first positioning post 12 into the positioning hole 22 at the lower end of the fixture platform 2, reducing the installation difficulty, improving the installation efficiency, and ensuring the accuracy of the installation position of the fixture platform 2; for the second positioning post 23, the tapered guide head 231 at its upper end can also play a similar guiding role when positioning and installing with the upper fixture or auxiliary device, which facilitates the quick and accurate completion of the entire cutting platform structure.

[0033] As a further preferred embodiment, the fixture platform 2 has two sets of positioning pins 25 on each side, and two sets of positioning posts 23 on each side. The positioning pins 25 are used to position the heat sink on the fixture platform 2. The arrangement of two sets on each side can limit the heat sink from multiple directions, ensuring the accuracy and stability of the heat sink's placement on the fixture platform 2, and meeting the positioning requirements of high-precision cutting. The positioning posts 23, with two sets on each side, can provide more stable positioning support for the upper fixture or auxiliary devices.

[0034] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
