Description

Technical Field

[0001] This utility model relates to the field of screen printing technology for radiators, and more specifically, to a universal printing fixture for radiators. Background Technology

[0002] With the rapid development of technology, the execution speed of heat sources such as chips and central processing units is getting faster and faster, and the heat generated is also getting higher and higher. In order to dissipate the high temperature generated by the heat source and enable the heat source to operate normally at the permissible temperature, a high-efficiency heat sink with excellent heat dissipation performance is usually applied to the heat overflow surface of the heat source to assist in heat dissipation.

[0003] High-efficiency heat sinks are typically composed of multiple components, each with its own function, such as heat conduction, heat dissipation, and airflow generation. They work together to achieve high-efficiency heat dissipation.

[0004] Heat sinks typically require screen printing of thermal grease. During screen printing, the heat sink needs to be fixed in place, necessitating the use of heat sink fixing fixtures. Traditional heat sink fixing fixtures are custom-made to fit the shape of the heat sink, requiring a different fixture for each type of heat sink. This results in a large number of fixtures and a significant need for storage space, thereby increasing product costs and reducing product competitiveness. Utility Model Content

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] Example 1, please refer to Figure 1 and Figure 2 This utility model provides a universal printing and fixing fixture for radiators, which includes a base 1. Two three-dimensional adjustment structures 2 are provided on the base 1. Each three-dimensional adjustment structure 2 includes an X-axis slide rail 21, an X-axis slider 22 is provided on each X-axis slide rail 21, a Y-axis slide rail 23 is provided on each X-axis slider 22, a Y-axis slider 24 is provided on each Y-axis slide rail 23, and a positioning post 25 perpendicular to the plane of the base 1 is provided on each Y-axis slider 24. A length adjustment positioning block 3 is provided on one side of the base 1. The length adjustment positioning block 3 can slide and be fixed along the Y-axis. An X-axis positioning block 4 is provided on the base 1 located on one side of the length adjustment positioning block 3. The two screw holes of the radiator are respectively fitted onto two positioning posts 25. The two positioning posts 25 are used to position the two points of the radiator. Then, the length adjustment positioning block 3 is used to position the length of the radiator. The positioning positions of the two points of the radiator and the positioning positions of the length of the radiator are adjustable. The three-dimensional adjustment structure 2 is three-dimensionally adjustable and can be adapted to more than 90% of the radiators on the market. This achieves the universality of the fixing fixture, reduces the number of fixing fixtures, saves the storage space of fixing fixtures, reduces the holding cost of fixing fixtures, improves the trial production progress of new models, quickly responds to the trial production of new products, and facilitates the management of fixing fixtures.

[0031] Furthermore, the length adjustment positioning block 3 is provided with a sliding groove 31, which is parallel to the Y-axis, and an adjustment fixing post 32 is provided on the sliding groove 31. In this embodiment, there are two sliding grooves 31 and two adjustment fixing posts 32, and the position of the length adjustment positioning block 3 is adjusted by adjusting the fixed position of the sliding groove 31 on the adjustment fixing post 32. Of course, in other embodiments, the sliding groove 31 can also be set on the base 1, and the length adjustment positioning block 3 can be slidably set on the sliding groove 31, which can also realize the length adjustment of the heat sink.

[0032] Please see Figure 3 Furthermore, there are an even number of three-dimensional adjustment structures 2, and each pair of three-dimensional adjustment structures 2 is grouped together. In this embodiment, there are four three-dimensional adjustment structures 2, and each pair of three-dimensional adjustment structures 2 is grouped together, for a total of two groups.

[0033] Furthermore, the base 1 has multiple positioning cavities 5, and each positioning cavity 5 has a corresponding three-dimensional adjustment structure 2, so that the three-dimensional adjustment structure 2 is hidden in the positioning cavity 5. However, the plane of the positioning column 25 should be slightly higher than the plane of the base 1 to avoid friction between the bottom of the heat sink and the base 1.

[0034] Furthermore, the length adjustment positioning block 3 is elongated and parallel to the Y-axis, thus better concealing the heat sink.

[0035] Furthermore, the base 1 is made of black bakelite, and the positioning post 25 is a linear bearing.

[0036] Example 2, please refer to Figure 4 As a further optimization of Embodiment 1, in this embodiment, each three-dimensional adjustment structure 2 includes two X-axis slide rails 21, each X-axis slide rail 21 is provided with an X-axis slider 22, and a Y-axis slide rail 23 is mounted on the two X-axis sliders 22. A Y-axis slider 24 is provided on the Y-axis slide rail 23, and a positioning post 25 perpendicular to the plane of the base 1 is provided on the Y-axis slider 24. In this way, the Y-axis slide rail 23 can span across the X-axis slider 22, so that the Y-axis slide rail 23 can be fixed more stably. Of course, only one X-axis slide rail 21 and X-axis slider 22 can be used. However, if this structure is to be fixed stably, the volume of the X-axis slide rail 21 and X-axis slider 22 needs to be made larger. Both of these methods will increase the cost, but can fix the Y-axis slide rail 23 more stably. In actual production, adjustments can be made according to actual needs.

[0037] Please see Figure 5Furthermore, a limiting block 33 parallel to the movable direction of the length adjustment positioning block 3 is fixed to the end of the length adjustment positioning block 3. The length adjustment positioning block 3 and the limiting block 33 together achieve the fixation and positioning of the heat sink, so that the heat sink can be more stably fixed on the fixing fixture. More preferably, the limiting block 33 can slide along the length adjustment positioning block 3 to adjust the width between the limiting block 33 and the X-axis positioning block 4, thereby accommodating heat sinks of different sizes.

[0038] Furthermore, a buffer pad 34 is provided on the side of the length adjustment positioning block 3 facing the base 1, so that the heat sink and the length adjustment positioning block 3 can be buffered by the buffer pad 34, so as to avoid the length adjustment positioning block 3 from bumping the heat sink and also to avoid wear of the length adjustment positioning block 3 during long-term production. When the buffer pad 34 is worn, only the buffer pad 34 needs to be replaced, and there is no need to replace the length adjustment positioning block 3.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
