Description

Technical Field

[0001] This application relates to the field of heat sink processing technology, and in particular to a welding fixture. Background Technology

[0002] Heat sinks are components used to dissipate heat from electronic devices, and are usually made of metals with good thermal conductivity, such as aluminum and copper.

[0003] Currently, the manufacturing process of heat sinks mainly includes steps such as turning, grinding, tooth removal, and shaping. More complex heat sinks often require soldering to create a combined heat dissipation structure. During the soldering process, the components of the heat sink are prone to relative displacement, leading to failed soldering. Utility Model Content

[0004] To help prevent misalignment of the components of the heat sink during the soldering process in the soldering machine and to ensure a certain degree of yield of the soldered products, this application provides a soldering fixture.

[0005] The welding fixture provided in this application adopts the following technical solution:

[0006] A welding fixture includes an upper positioning clamp, a lower positioning clamp, and a locking member. The upper and lower positioning clamps are used to clamp multiple components of a heat sink. Both the upper and lower positioning clamps have multiple through holes. The locking member is used to fix the upper and lower positioning clamps relative to each other.

[0007] Preferably, the locking element includes a clamping seat, a threaded rod threaded through the clamping seat, and a clamping plate disposed on the threaded rod. The clamping seat has an opening for the upper positioning clamp and the lower positioning clamp to move in or out. The clamping plate is used to press against the side of the upper positioning clamp away from the lower positioning clamp.

[0008] Preferably, the locking component includes a locking bolt passing through the lower positioning clamp and a locking nut threaded onto the locking bolt. The locking bolt is used to pass through a through hole in the upper positioning clamp, and the locking nut is used to abut against the side of the upper positioning clamp away from the lower positioning clamp.

[0009] Preferably, the positioning upper clamp is provided with an upper positioning protrusion or an upper positioning groove, which is used to abut against the components of the radiator.

[0010] Preferably, the lower positioning clamp is provided with a lower positioning protrusion or a lower positioning groove, which is used to abut against the components of the radiator.

[0011] Preferably, the lower positioning clamp is provided with a plurality of limiting plates, which are arranged at intervals along the circumference of the lower positioning clamp, and the limiting plates are used to abut against the side wall of the upper positioning clamp.

[0012] Preferably, the limiting plate and the positioning lower clamping plate are connected by bolts.

[0013] Preferably, a limiting notch is provided on the positioning upper clamp.

[0014] Preferably, the positioning lower clamp is provided with a positioning post, which is used to pass through the positioning hole on the radiator component.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] Multiple components of the radiator are placed on the lower positioning clamp, and then the upper positioning clamp is placed over the components, positioning them between the upper and lower positioning clamps. The upper and lower positioning clamps are then fixed in place by locking devices, thus defining the position of each component. The upper and lower positioning clamps holding the radiator components are then placed into an automatic soldering machine and soldered through the through-holes. This process helps to prevent misalignment of the components during the soldering process, thus ensuring a higher yield of the finished soldered products. Attached Figure Description

[0023] The following combination Figures 1-5This application will be described in further detail.

[0024] This application discloses a welding fixture. (Refer to...) Figure 1 The welding fixture includes an upper positioning clamp 1, a lower positioning clamp 2, and a locking component. Both the upper positioning clamp 1 and the lower positioning clamp 2 are rectangular plates, and their melting points are much higher than those of tin. The upper positioning clamp 1 and the lower positioning clamp 2 are used to clamp multiple components of the heat sink. Both the upper positioning clamp 1 and the lower positioning clamp 2 have multiple through holes 3. Furthermore, the multiple through holes 3 on the upper positioning clamp 1 and the lower positioning clamp 2 are arranged in a matrix, and the through holes 3 on the upper positioning clamp 1 are used to align with the through holes 3 on the lower positioning clamp 2, so that the heat sink components between the upper positioning clamp 1 and the lower positioning clamp 2 can be welded. The locking component is used to fix the upper positioning clamp 1 and the lower positioning clamp 2 relative to each other.

[0025] Before use, the heat sink components are tin-plated as needed. Then, the multiple components of the heat sink are placed on the lower positioning clamp 2 according to their positions. Next, the upper positioning clamp 1 is placed over the multiple components of the heat sink, so that each component of the heat sink is located between the upper positioning clamp 1 and the lower positioning clamp 2. Then, the upper positioning clamp 1 and the lower positioning clamp 2 are fixed relative to each other by locking components, thereby limiting the position of each component of the heat sink. Then, the upper positioning clamp 1 and the lower positioning clamp 2 holding the heat sink components are placed into an automatic soldering machine for soldering. This helps to prevent the components of the heat sink from being misaligned during the soldering process of the soldering machine, and to a certain extent, ensures the yield of the soldered products.

[0026] Reference Figure 1 and Figure 2 To facilitate the relative fixation of the upper positioning clamp 1 and the lower positioning clamp 2, the locking components include a clamping seat 4, a threaded rod 5, and a clamping disc 6. The clamping seat 4 is U-shaped with an opening 7, which allows the upper positioning clamp 1 and the lower positioning clamp 2 to move in or out. The threaded rod 5 is threaded onto the clamping seat 4, and its rotation axis is parallel to the plane of the clamping seat 4. One end of the threaded rod 5 extends into the opening 7 of the clamping seat 4, and the other end is located outside the clamping seat 4. An operating ring 15 is fixed to the end of the threaded rod 5 outside the clamping seat 4 to facilitate rotation of the threaded rod 5. The clamping disc 6 is fixed to the end of the threaded rod 5 located in the opening 7 of the clamping seat 4 and is used to press against the surface of the upper positioning clamp 1 away from the lower positioning clamp 2. To improve the clamping and fixing effect of the upper positioning clamp 1 and the lower positioning clamp 2, multiple locking components can be used to relatively fix the upper positioning clamp 1 and the lower positioning clamp 2 in actual use.

[0027] When it is necessary to fix the upper positioning clamp 1 and the lower positioning clamp 2 relative to each other, the clamping seat 4 is placed on the upper positioning clamp 1 and the lower positioning clamp 2 that clamp the radiator component, so that the plane of the clamping seat 4 is perpendicular to the plane of the upper positioning clamp 1. The abutting plate 6 is located on the side closer to the upper positioning clamp 1. Then, the side of the lower positioning clamp 2 away from the upper positioning clamp 1 is made to abut against the side of the clamping seat 4 away from the threaded rod 5. Then, the threaded rod 5 is rotated, so that the threaded rod 5 drives the abutting plate 6 to rotate towards the direction closer to the upper positioning clamp 1, until the abutting plate 6 abuts against the side of the upper positioning clamp 1 away from the lower positioning clamp 2. Through the threaded engagement between the threaded rod 5 and the clamping seat 4, the threaded rod 5 is not easy to slip or rotate. Then, multiple locking parts are arranged around the circumference of the upper positioning clamp 1 and the lower positioning clamp 2, which helps to ensure the clamping and limiting effect of the upper positioning clamp 1 and the lower positioning clamp 2 on the radiator component.

[0028] Reference Figure 3 and Figure 4 The upper positioning plate 1 is provided with an upper positioning protrusion 10 or an upper positioning groove on the side near the lower positioning plate 2. The upper positioning protrusion 10 or the upper positioning groove is used to abut against the components of the heat sink. Specifically, the upper positioning plate 1 is integrally formed with an upper positioning protrusion 10 on the side near the lower positioning plate 2. The upper positioning protrusion 10 can abut against the uneven surface of the water-cooled heat sink.

[0029] Reference Figure 3 The lower positioning plate 2 has a lower positioning protrusion or a lower positioning groove 11 on the side near the upper positioning plate 1. The lower positioning protrusion or lower positioning groove 11 is used to abut against the components of the radiator. Specifically, the lower positioning plate 2 has a lower positioning groove 11 on the side near the upper positioning plate 1 to adapt to the specific structure of the radiator. The specific shape and size of the upper positioning protrusion 10 and the lower positioning groove 11 are set according to the actual structure of the radiator components, which helps to improve the limiting effect on the various components of the radiator.

[0030] Reference Figure 3 Multiple limiting plates 12 are fixedly provided on the side of the lower positioning clamp 2. The multiple limiting plates 12 are arranged at intervals along the circumference of the lower positioning clamp 2. Specifically, there are three limiting plates 12, and the three limiting plates 12 are located on three sides of the lower positioning clamp 2. The limiting plates 12 extend toward the side closer to the lower positioning groove 11. The limiting plates 12 are used to abut against the side wall of the upper positioning clamp 1.

[0031] When the positioning clamp 1 covers the radiator component, the multiple limiting plates 12 can guide the downward movement of the positioning clamp 1 so that the positioning clamp 1 and the through hole 3 on the positioning lower clamp 2 can be aligned, which facilitates the clamping and limiting of the radiator.

[0032] Reference Figure 3Furthermore, the limiting plate 12 and the positioning lower clamping plate 2 are connected by bolts, thereby realizing a detachable connection between the limiting plate 12 and the positioning lower clamping plate 2, so as to facilitate the disassembly and assembly of the limiting plate 12 as needed.

[0033] Reference Figure 1 and Figure 3 A limiting notch 13 is provided on the positioning clamp 1. The shape and size of the limiting notch 13 are set according to the structure of the heat sink component. For the regularly shaped protrusions on the heat sink component, the limiting notch 13 is provided to allow the protrusions of the heat sink component to extend out, so as to further realize positioning. At the same time, it can effectively reduce the thickness of the entire tooling during use, and provide convenience for subsequent soldering.

[0034] Reference Figure 3 The positioning lower clamping plate 2 has an integrally formed positioning post 14, which passes through the positioning hole on the radiator component. Furthermore, multiple positioning posts 14 are provided, and their number, size, and shape are set according to actual needs. Through the cooperation of the positioning post 14 with the positioning hole on the radiator component, the radiator component can be further limited, making it less prone to displacement during subsequent welding, thus helping to ensure the yield rate of the welded product.

[0035] The implementation principle of Embodiment 1 of this application is as follows: Before use, the heat sink components are tin-plated as needed. Then, multiple components of the heat sink are placed on the lower positioning clamp 2, so that the lower positioning groove 11 on the lower positioning clamp 2 engages with the structure on the heat sink component, and the positioning post 14 on the lower positioning clamp 2 engages with the positioning hole on the heat sink component. Then, the upper positioning clamp 1 is placed on the heat sink component, and the multiple components of the heat sink are clamped and positioned by the upper positioning clamp 1 and the lower positioning clamp 2. Then, the clamping seat 4 is sleeved on the upper positioning clamp 1 and the lower positioning clamp 2 that clamp the heat sink components. The plane of the clamping seat 4 is perpendicular to the plane of the upper positioning clamp 1, and the abutment plate 6 is located near the positioning... Next, the side of the upper clamping plate 1 away from the upper clamping plate 1 is aligned with the side of the clamping seat 4 away from the threaded rod 5. Then, the threaded rod 5 is rotated, causing the clamping plate 6 to rotate towards the upper clamping plate 1 until the clamping plate 6 is pressed against the side of the upper clamping plate 1 away from the lower clamping plate 2. This achieves relative fixation of the upper clamping plate 1 and the lower clamping plate 2, thereby limiting the position of each component of the radiator. Then, the upper clamping plate 1 and the lower clamping plate 2 holding the radiator components are placed into an automatic soldering machine for soldering. This helps to prevent misalignment of the components of the radiator during the soldering process and to a certain extent ensures the yield rate of the soldered products.

[0036] Example 2:

[0037] Reference Figure 5The difference between this embodiment and embodiment 1 is that the locking component includes a locking bolt 8 and a locking nut 9. The locking bolt 8 passes through the lower positioning clamping plate 2, and the axial direction of the locking bolt 8 is perpendicular to the plane of the lower positioning clamping plate 2. The locking bolt 8 is used to pass through the corresponding through hole 3 on the upper positioning clamping plate 1. To improve the locking effect, multiple locking bolts 8 are arranged. The locking nut 9 is threadedly connected to the locking bolt 8 and is used to abut against the side of the upper positioning clamping plate 1 away from the lower positioning clamping plate 2.

[0038] The implementation principle of Embodiment 2 of this application is as follows: After the radiator component is placed on the lower positioning clamp 2, the upper positioning clamp 1 is placed on the lower positioning clamp 2, and the locking bolt 8 on the lower positioning clamp 2 passes through the corresponding through hole 3 on the upper positioning clamp 1. Then, the locking nut 9 is screwed onto the locking bolt 8, so that the locking nut 9 abuts against the side of the upper positioning clamp 1 away from the lower positioning clamp 2, thereby fixing the upper positioning clamp 1 and the lower positioning clamp 2, so as to limit the position of the radiator component.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
