Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of foam wrapping, especially a wrapping jig of heat dissipation foam. BACKGROUND

[0002] Foam, as a material with good elasticity and cushioning performance, is often used as a shock-absorbing and cushioning layer in electronic devices. However, traditional foam materials perform poorly in terms of heat dissipation, failing to meet the demand for efficient heat dissipation of modern electronic devices. To solve this problem, researchers have developed various foam materials with heat dissipation functions, such as graphite heat-conductive foam and silica gel foam. These materials combine the properties of heat-conductive materials and foam, maintaining the shock-absorbing and cushioning performance of foam while enhancing heat dissipation.

[0003] However, in actual production processes, how to efficiently combine heat-conductive materials (such as graphite sheets) with foam materials and form a tight and stable wrapping structure has become a technical challenge. Traditional manual wrapping methods are not only inefficient but also prone to unstable product quality due to differences in workers' levels. SUMMARY

[0004] To solve the problems in the prior art, the utility model provides a wrapping jig of heat dissipation foam.

[0006] A wrapping jig of heat dissipation foam, comprising:

[0007] A jig table, a wrapping groove is formed on the jig table, the wrapping groove includes an inlet and an outlet, and the cross-sectional size of the wrapping groove gradually decreases along the direction from the inlet to the outlet;

[0008] A first guide, comprising a first connecting part and a first guide part, the first connecting part is connected to the top of one side of the wrapping groove, the first guide part is connected to the first connecting part, and the first guide part has a first gap with the inner wall of one side of the wrapping groove;

[0009] A second guide, comprising a second connecting part and a second guide part, the second connecting part is connected to the other side of the wrapping groove, the second guide part is connected to the second connecting part, and the second guide part has a second gap with the inner wall of the other side of the wrapping groove.

[0010] Preferably, the distance between the first guide part and the second guide part gradually decreases along the direction from the inlet to the outlet.

[0011] Preferably, the first guide part is arranged in parallel with the inner wall of one side of the wrapping groove.

[0013] Preferably, one end of the first guide part is located in the same horizontal plane with the outlet side wall of the wrapping groove, and the other end of the first guide part is located between the outlet and the inlet of the wrapping groove.

[0014] Preferably, one end of the second guide part is located in the same horizontal plane with the outlet side wall of the wrapping groove, and the other end of the second guide part is located between the outlet and the inlet of the wrapping groove.

[0015] Preferably, the first guide part and the second guide part are closed or corresponding at the outlet, so that the outlet forms a cross-section completely closed nozzle or a gap is left between the first guide part and the second guide part.

[0016] Preferably, in the direction from the inlet to the outlet, the inner wall of the wrapping groove gradually transitions from an arc surface to a flat surface.

[0027] Example 1

[0028] A heat dissipation foam wrapping fixture, such as Figure 1 As shown, the device includes a fixture table 1, on which a wrapping groove 10 is formed. The wrapping groove 10 includes an inlet 11 and an outlet 12, and the cross-sectional dimension of the wrapping groove 10 gradually decreases along the direction from the inlet 11 to the outlet 12. Figure 2As shown, it also includes a first guide 2, which includes a first connecting part 20 connected with a top of one side of the wrapping groove 10 and a first guide part 21 connected with the first connecting part 20, and a first gap 22 is formed between the first guide part 21 and an inner wall of the one side of the wrapping groove 10; and a second guide 3, which includes a second connecting part 30 connected with the other side of the wrapping groove 10 and a second guide part 31 connected with the second connecting part 30, and a second gap 32 is formed between the second guide part 31 and an inner wall of the other side of the wrapping groove 10.

[0029] The jig table 1 is usually made of a material with firmness and hardness, such as aluminum alloy or stainless steel, to ensure stability and durability during long-term use. The cross-sectional size of the wrapping groove 10 gradually decreases from the inlet 11 to the outlet 12, forming a structure similar to a cone or trapezoid, which facilitates the gradual compression and wrapping of the heat dissipation foam. In one possible implementation, the inner wall of the wrapping groove 10 gradually transitions from an arc surface to a flat surface from the inlet 11 to the outlet 12. This helps the heat dissipation foam gradually adapt to the shape change during the wrapping process, reducing resistance.

[0030] It should be noted that the size of the inlet 11 is slightly larger than the original size of the heat dissipation foam, which facilitates the placement of the foam to be wrapped. The first connecting part 20 is firmly connected with the top of one side of the wrapping groove 10 and can be fixed by welding or other methods. The first gap 22 exists between the first guide part 21 and the inner wall of one side of the wrapping groove 10, which helps to wrap the foam when it passes through the wrapping groove. The second gap 32 exists between the second guide part 31 and the inner wall of the other side of the wrapping groove 10, which helps to place the heat-conducting material and assist the wrapping process when the foam passes through the wrapping groove.

[0031] It should be noted that before wrapping, the two surfaces of the heat dissipation film need to be respectively pasted with adhesive to obtain a standby heat dissipation film. The surface of the silica gel foam is treated with a surface treatment agent to obtain a standby silica gel foam. When performing coating molding, the standby silica gel foam is placed on the standby heat dissipation film to form the material to be coated.

[0032] In this embodiment, the foam material to be wrapped is prepared. According to the size and shape of the foam material, the positions of the first guide 2 and the second guide 3 are adjusted to ensure proper gaps, and the heat dissipation foam is placed at the entrance 11 of the wrapping groove 10. Under the action of the external pushing force, the heat dissipation foam moves along the wrapping groove 10 towards the outlet 12. In this process, the first guide 2 and the second guide 3 guide the heat dissipation foam through the first gap 22 and the second gap 32, ensuring that it moves along the predetermined path. During the advancement of the material to be wrapped in the channel, the inner walls of the wrapping groove gradually extrude the standby heat dissipation film outside the standby silica gel foam, so that the standby heat dissipation film tightly wraps the standby silica gel foam, obtaining the heat dissipation foam.

[0033] Embodiment two

[0034] As shown in Figure 3 With Figure 4 the distance between the first guide part 21 and the second guide part 31 gradually decreases in the direction from the entrance 11 to the outlet 12. The first guide part 21 is arranged in parallel with one side inner wall of the wrapping groove 10. The second guide part 31 is arranged in parallel with the other side inner wall of the wrapping groove 10. One end of the first guide part 21 is located at the same horizontal plane as the side wall of the outlet 12 of the wrapping groove 10, and the other end of the first guide part 21 is located between the outlet 12 and the entrance 11 of the wrapping groove 10. One end of the second guide part 31 is located at the same horizontal plane as the side wall of the outlet 12 of the wrapping groove 10, and the other end of the second guide part 31 is located between the outlet 12 and the entrance 11 of the wrapping groove 10.

[0035] As shown in Figure 2 the other end of the first guide part 21 is located between the outlet 12 and the entrance 11 of the wrapping groove 10, and the other end of the second guide part 31 is located between the outlet 12 and the entrance 11 of the wrapping groove 10, which means that there is a certain distance between the end of the first guide part 21 and the second guide part 31 close to the outlet 12 and the outermost side of the outlet 12. This part between the outermost side of the outlet 12 and the first guide part 21 and the second guide part 31 is to make it easier to place the material to be wrapped.

[0036] Wherein, the first guide part 21 is arranged in parallel with one side inner wall of the wrapping groove 10, ensuring that it provides stable lateral guidance for the heat dissipation foam during wrapping, and the distance between the first guide part 21 and the second guide part 31 gradually decreases in the direction from the entrance 11 to the outlet 12, which helps the heat dissipation foam to be gradually compressed and tightly fitted during wrapping.

[0037] In one possible implementation, the first guide portion 21 and the second guide portion 31 are closed or corresponding at the outlet 12, so that the outlet 12 forms a cross-sectionally completely closed nozzle or a gap between the first guide portion 21 and the second guide portion 31 is left. In this embodiment, the first guide portion 21 and the second guide portion 31 correspond at the outlet 12, and a gap is left between the first guide portion 21 and the second guide portion 31.

[0038] Since the cross-sectional size of the wrapping groove gradually decreases from the inlet 11 to the outlet 12, and the distance between the first guide portion 21 and the second guide portion 31 also gradually decreases, this design can still ensure that the heat dissipation foam is gradually compressed and closely fitted during the wrapping process. The existence of the gap is to ensure the smooth progress of the wrapping process while maintaining close fitting.

[0039] It should be noted that the first guide portion 21 and the second guide portion 31 are symmetrically arranged along the center line of the wrapping groove. The first guide portion 21 and the second guide portion 31 are symmetrically arranged along the center line of the wrapping groove, which helps to maintain the symmetry of the heat dissipation foam during the wrapping process and prevent it from being offset or twisted during the wrapping process.

[0040] The two sides of the heat dissipation film are respectively adhered with adhesive to obtain a standby heat dissipation film. At the same time, the silica gel foam is subjected to necessary surface treatment to improve its adhesion with the heat dissipation film. The treated silica gel foam is placed on the standby heat dissipation film to form a material to be wrapped.

[0041] In the embodiment, the silica gel foam to be wrapped is placed at the entrance of the wrapping groove. Since the entrance size is slightly larger than the original size of the foam, the foam can be easily placed into the wrapping groove, and under the action of external pushing force or pulling force, the foam starts to move in the outlet direction of the wrapping groove. With the movement of the foam, the cross-sectional size of the wrapping groove gradually decreases, generating a compression force on the foam, and when the edge of the foam contacts the inner wall of the wrapping groove, the edge of the foam starts to be subjected to an upward force due to the decreasing cross-sectional size of the wrapping groove. At the same time, the first guide portion and the second guide portion guide the edge of the foam through the first gap and the second gap, so that the edge of the foam is turned up along the inner wall of the wrapping groove. In this process, the degree of turning up of the edge of the foam is controlled by the size of the first gap and the second gap, and as the foam continues to move in the outlet direction, the cross-sectional size of the wrapping groove further decreases, and the degree of turning up of the edge of the foam also gradually increases. At the same time, the inner wall of the wrapping groove gradually extrudes the standby heat dissipation film on the outside of the silica gel foam, so that the heat dissipation film is tightly attached to the foam. Due to the turning up, the heat dissipation film can better wrap the foam, improving the overall wrapping quality. When the foam completely passes through the wrapping groove and reaches the outlet, the heat dissipation film on the outside of the foam has been tightly wrapped on the silica gel foam, and the edge of the foam has been successfully turned up. At this time, the wrapped heat dissipation foam can be taken out for subsequent processing or assembly. In the coating forming process, the gradually reduced diameter of the wrapping groove is used to gradually complete the coating action of the heat dissipation film on the outside of the foam on the silica gel foam. At the same time, due to the gradually narrowing structure of the wrapping groove, the gradually extruding method can be used to realize the dense extrusion of the silica gel foam, forming the tight wrapping and adhesion of the heat dissipation foam.

[0042] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application.
