[0035] Figure 9 for Figure 1 The image shows a 3D rendering of the SLD chip assembly fixture mounted on the heating stage. Figure 10 for Figure 9 The image shows a 3D rendering of the SLD chip assembly fixture holding the chip and the heat sink.

[0036] like Figures 1-10As shown, the SLD chip assembly fixture includes a base 1, a clamping assembly 2, and an elastic element 3. The base 1 has a movable cavity 4 extending through it in a first direction and a movable groove 5 extending through it in a second direction. The movable groove 5 communicates with the movable cavity 4, and the first direction and the second direction are perpendicular to each other. The clamping assembly 2 includes a clamping plate 21 and a movable plate 22 fixedly connected to the clamping plate 21. The clamping plate 21 is disposed in the movable cavity 4, and at least a portion of the movable plate 22 is disposed in the movable groove 5 and is movably connected to the movable groove 5. The first end of the elastic element 3 is fixedly connected to the side surface of the clamping plate 21 facing the movable plate 22, and the second end of the elastic element 3 is fixedly connected to the inner wall of the base 1 communicating with the movable groove 5.

[0037] Before using the SLD chip assembly fixture, apply solder paste to the corresponding area of ​​the heat sink, place the chip 10 on the solder paste, and then fix the base 1 to the heating platform 9. The upper surface of the heating platform 9 blocks the movable cavity 4. Push the clamping plate 21 towards the moving groove 5. The clamping plate 21 will then drive the moving plate 22 to move towards the moving groove 5. The part of the moving plate 22 exposed in the movable cavity 4 will gradually enter the moving groove 5. At the same time, the elastic element 3 will be compressed by the clamping plate 21, accumulating elastic potential energy. When the distance between the clamping plate 21 and the inner wall of the movable cavity 4 on the side opposite to the moving groove 5 is sufficient to place the heat sink and the chip 10 as a whole, stop pushing the clamping plate 21 and place the heat sink and the chip 10 as a whole into the movable cavity 4, with the heat sink and the chip 10 as a whole abutting against the inner wall of the movable cavity 4 on the side opposite to the moving groove 5. When the external force pushing the clamping plate 21 is released, the elastic element 3 loses the external pressure and releases its elastic force. The elastic force of the elastic element 3 pushes the clamping plate 21 toward the heat sink and chip 10 until the clamping plate 21 abuts against the heat sink and chip 10. The elastic force of the elastic element 3 maintains the pushing force on the clamping plate 21, so that the heat sink and chip 10 are fixed in the movable cavity 4 under the abutment action of the clamping plate 21 and cannot move. Then the heating stage 9 is heated to perform the subsequent welding operation on the heat sink and chip 10.

[0038] Using the SLD chip assembly fixture of this utility model, after the base 1 is fixed to the heating platform 9, the upper surface of the heating platform 9 and the movable cavity 4 enclose a space for placing the heat sink and the chip 10. At the same time, the elastic force of the elastic element 3 pushes the clamping plate 21, so that the clamping plate 21 tightly abuts against the heat sink and the chip 10 as a whole, so that the heat sink and the chip 10 are stably clamped in the movable cavity 4. During the entire process of welding and fixing the heat sink and the chip 10, neither of them will move, ensuring the consistency of their assembly and the welding and fixing effect.

[0039] like Figures 1-7As shown, in this embodiment, the cross-section of the base 1 is square. The movable cavity 4 penetrates the center of the base 1 in the first direction, that is, along the longitudinal direction of the base 1, and has a rectangular cross-section. The moving groove 5 extends horizontally in the second direction, that is, perpendicular to the axial direction of the base 1, with one end penetrating the side end face of the base 1 and the other end extending to the movable cavity 4. The inner wall of the movable cavity 4 is the inner wall of the base 1. Figure 1 , Figure 2 and Figure 8 As shown, both the clamping plate 21 and the moving plate 22 of the clamping assembly 2 are cuboid plates. The moving plate 22 is vertically and fixedly connected to the side surface of the clamping plate 21 facing the moving groove 5. A portion of the moving plate 22 is inserted into the moving groove 5, and a portion protrudes from the movable cavity 4. The elastic element 3 is a spring. One end of the spring is fixedly connected to the center of the side surface of the clamping plate 21 facing the moving plate 22, and the other end is fixedly connected to the inner wall of the base 1 that communicates with the moving groove 5, that is, the inner wall of the movable cavity 4 that communicates with the moving groove 5. Figure 9 and Figure 10 As shown, during the process of pushing the clamping plate 21 to the left, the moving plate 22 moves to the left accordingly, gradually entering the moving groove 5. The elastic element 3 is compressed accordingly, and the space of the movable cavity 4 on the right side of the clamping plate 21 gradually increases. When this space is sufficient to accommodate the heat sink and the chip 10 as a whole, the pushing of the clamping plate 21 is stopped, and the heat sink and the chip 10 as a whole are placed into the movable cavity 4 on the right side of the clamping plate 21. The clamping plate 21 is released, and under the pushing action of the elastic force of the elastic element 3, the clamping plate 21 drives the moving plate 22 to move towards the chip 10 until it comes into contact with the heat sink and the chip 10, so that the heat sink and the chip 10 are stably clamped between the clamping plate 21 and the inner wall of the movable cavity 4, preventing them from shifting in position during the welding and fixing process. According to the actual application, the specific shape and size of the base 1, the clamping plate 21 and the moving plate 22 can be adjusted, and the elastic element 3 can also be selected from other elastic structures besides springs.

[0040] Optionally, the clamping assembly 2 further includes a limiting post 23, which is fixedly connected to the side surface of the clamping plate 21 facing the moving plate 22, and the first end of the elastic member 3 is fitted with the limiting post 23. In this arrangement, the limiting post 23 guides the elastic member 3, allowing the elastic member 3 to deform along the extension direction of the limiting post 23 during compression or elongation, thus preventing the elastic member 3 from moving in a direction other than its axial direction.

[0041] like Figure 1 , Figure 2 and Figure 8As shown, in this embodiment, the limiting post 23 is fixedly connected to the center position of the clamping plate 21 on the side facing the moving plate 22. The limiting post 23 is set as a cylinder, horizontally arranged in the axial direction, and coaxially arranged with the elastic element 3. The outer diameter of the limiting post 23 matches the inner diameter of the elastic element 3, so as not to affect the deformation of the elastic element 3, and to constrain the elastic element 3 so that it will not move in the direction of extension and retraction.

[0042] Optionally, a limiting hole 6 is provided on one inner wall of the base 1 that connects to the moving groove 5. The second end of the elastic member 3 is inserted into the limiting hole 6 and fixedly connected to the inner wall of the limiting hole 6. The limiting hole 6 and the limiting post 23 are coaxially arranged. With this arrangement, the movement of the elastic member 3 is constrained by the cooperation of the limiting hole 6 and the limiting post 23, so that the elastic member 3 can only move along its axial direction.

[0043] like Figure 3 and Figure 5 As shown, in this embodiment, the limiting hole 6 is opened on the inner wall of the base 1, that is, on the inner wall of the movable cavity 4, and the inner wall of this side is connected to the moving groove 5. The inner diameter of the limiting hole 6 matches the outer diameter of the elastic member 3, so that one end of the elastic member 3 can be fixed in the limiting hole 6.

[0044] Optionally, the movable groove 5 includes a first groove segment 51 and a second groove segment 52 that are connected. The first groove segment 51 is connected to the movable cavity 4, and the extension length of the second groove segment 52 is less than the extension length of the first groove segment 51. The clamping assembly 2 also includes a limiting block 24, which is fixedly connected to the movable plate 22. The movable plate 22 is disposed in the first groove segment 51 and is movably connected to the first groove segment 51. The limiting block 24 is disposed in the second groove segment 52 and is movably connected to the second groove segment 52.

[0045] When the movable plate 22 moves toward the movable cavity 4 in the first slot 51, the limiting block 24 moves synchronously in the second slot 52. However, the extension length of the second slot 52 is less than the extension length of the first slot 51, that is, the second slot 52 is not connected to the movable cavity 4. Therefore, when the limiting block 24 moves to the end position of the second slot 52, it cannot continue to move toward the movable cavity 4. The movable plate 22, which is fixedly connected to the limiting block 24, and the clamping plate 21, which is fixedly connected to the movable plate 22, also cannot continue to move. With this setting, after the heat sink and the chip 10 are placed, when the external force applied to the clamping plate 21 is released, the elastic member 3 is constrained by the length of movement of the limiting block 24 in the second slot 52 during the process of restoring its deformation and pushing the clamping plate 21 toward the chip 10. This prevents the elastic member 3 from releasing too much elastic force at the moment the external force is lost, which would cause the clamping plate 21 to damage the chip 10.

[0046] like Figure 4 and Figure 5As shown, in this embodiment, the first groove segment 51 has a longitudinal rectangular cross-section, penetrates the outer wall of the base 1, and extends to communicate with the movable cavity 4. The second groove segment 52 is above the first groove segment 51, that is, at the end of the first groove segment 51 away from the heating table 9, it communicates with the first groove segment 51. Its cross-section is a transverse rectangular shape, wider than the first groove segment 51, extends towards the movable cavity 4, and terminates at a certain distance from the movable cavity 4, not communicating with it. The cross-sections of the first groove segment 51 and the second groove segment 52 are generally T-shaped. Figure 8 As shown, the limiting block 24 is a cuboid block, fixed to the upper part of the moving plate 22 away from the clamping plate 21, with a width greater than the width of the moving plate 22. The cross-section of the limiting block 24 and the moving plate 22 is T-shaped to match the moving groove 5. Depending on the actual application, the specific fixed position of the limiting block 24 on the moving plate 22 can be adjusted. Correspondingly, the relative position of the second groove segment 52 and the first groove segment 51 is adjusted accordingly. As long as the movement of the limiting block 24 within the second groove segment 52 can constrain the movement of the moving plate 22 and the clamping plate 21, the movement can be constrained. The length of the second groove segment 52, i.e., the distance between the end point of the second groove segment 52 facing the movable cavity 4 and the movable cavity 4, is designed to ensure that the clamping plate 21 can tightly clamp the heat sink and chip 10 placed in the movable cavity 4, while also ensuring that when the external force applied to the elastic member 3 is released, the clamping plate 21 will not cause excessive compression and damage to the chip 10 under the elastic force of the elastic member 3.

[0047] Optionally, the first groove segment 51 penetrates the side surface of the base 1 that contacts the heating table 9, and the base 1 has a connecting groove 7 that penetrates the side surface of the base 1 that contacts the heating table 9 and communicates with the first groove segment 51 and the second groove segment 52. The limiting block 24 enters the second groove segment 52 through the connecting groove 7. This arrangement simplifies the connection process between the clamping assembly 2 and the base 1.

[0048] like Figure 7 As shown, the lower surface of the base 1, which is the side that contacts the heating platform 9, has a first groove segment 51 extending horizontally through the lower surface of the base 1. The left end of the groove penetrates the left end face of the base 1, and the right end extends to communicate with the movable cavity 4. A connecting groove 7 extends vertically along the lower surface of the base 1, with an extension length greater than the width of the first groove segment 51, and is perpendicular to the first groove segment 51. The connecting groove 7 extends towards the second groove segment 52 until it communicates with the second groove segment 52. Figure 2As shown, the limiting block 24 enters through the connecting groove 7 on the lower surface of the base 1 and moves upward until it enters the second groove segment 52. After the limiting block 24 enters the second groove segment 52, the moving plate 22 connected to the limiting block 24 simultaneously enters the corresponding first groove segment 51. Moving the limiting block 24 along the extending direction of the second groove segment 52, so that the limiting block 24 is away from the connecting groove 7, the limiting block 24 is constrained within the second groove segment 52 and cannot be removed, thus completing the connection between the clamping assembly 2 and the base 1.

[0049] Optionally, the base 1 has two movable slots 5 in the second direction; two movable plates 22 are provided, which are fixedly connected to the same side surface of the clamping plate 21 at intervals, and one movable plate 22 is inserted into one movable slot 5. By moving the two movable plates 22 in the corresponding movable slots 5, the clamping plate 21 can move more stably and is less prone to trajectory deviation when the two movable plates 22 drive the clamping plate 21 to move.

[0050] like Figure 8 As shown, in this embodiment, two movable plates 22 are arranged in parallel and perpendicularly connected to the left side of the clamping plate 21 at intervals. A limiting post 23 is disposed between the two movable plates 22. A limiting block 24 is fixed to the upper surface of each movable plate 22 at the end away from the clamping plate 21. Figure 4 and Figure 5 As shown, correspondingly, the two movable slots 5 respectively include a first slot segment 51 and a second slot segment 52 that are connected.

[0051] Optionally, the base 1 has a positioning hole 8 extending through it in the first direction. By pre-setting the positioning hole 8, after the base 1 is placed on the heating platform 9, bolts can be passed through the positioning hole 8 and the corresponding mounting holes on the heating platform 9 to achieve a detachable connection between the base 1 and the heating platform 9.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment, four positioning holes 8 are provided through the base 1, located at the four corners of the base 1. The specific location and number of positioning holes 8 on the base 1 can be adjusted according to actual application.

[0053] Optionally, the base 1 includes a first support portion 101 and a second support portion 102 fixedly connected. The first support portion 101 has a through-hole 5, and the second support portion 102 has a through-hole cavity 4. The height of the second support portion 102 is less than the height of the first support portion 101. The smaller height of the second support portion 102 with the cavity 4 facilitates the operation of the heat sink and the chip 10 after they are placed together in the cavity 4, avoiding the situation where the cavity 4 is too deep and would hinder the operation of placing and removing the heat sink and the chip 10.

[0054] like Figures 3-5As shown, in this embodiment, both the first support portion 101 and the second support portion 102 are rectangular parallelepiped plates. The first support portion 101 horizontally penetrates the moving groove 5, and the second support portion 102 longitudinally penetrates the movable cavity 4. The movable cavity 4 penetrates the end face of the second support portion 102 facing the first support portion 101, thus connecting the moving groove 5 and the movable cavity 4. After the first support portion 101 and the second support portion 102 are fixed, the three side walls of the movable cavity 4, as well as the side wall of the first support portion 101 facing the movable cavity 4 and located within the width of the movable cavity 4, together constitute the inner wall of the base 1. The first support portion 101 and the second support portion 102 have a height difference, forming a stepped structure. The second support portion 102 has a smaller height; therefore, as... Figure 9 and Figure 10 As shown, the vertical depth of the active cavity 4 is relatively shallow, making it more convenient to insert or remove the heat sink and chip 10. Depending on the actual application, the specific heights of the first support portion 101 and the second support portion 102, as well as the height difference between them, can be appropriately adjusted. The first support portion 101 and the second support portion 102 can be fixedly connected as independent entities, or they can be integrally formed.

[0055] Optionally, both the base 1 and the clamping assembly 2 are made of PTFE. PTFE can effectively prevent heat sinks and chip 10 from being scratched during clamping.

[0056] This utility model also provides a fixture assembly, including a heating platform 9, and an SLD chip assembly fixture as described in any of the above embodiments, wherein the base 1 of the SLD chip assembly fixture is fixed to the heating platform 9.

[0057] Using the fixture assembly of this utility model, after the base 1 is fixed to the heating platform 9, the upper surface of the heating platform 9 and the movable cavity 4 enclose a space for placing the heat sink and the chip 10. At the same time, the elastic force of the elastic element 3 pushes the clamping plate 21, so that the clamping plate 21 tightly abuts against the heat sink and the chip 10 as a whole, so that the heat sink and the chip 10 are stably clamped in the movable cavity 4. During the entire process of welding and fixing the heat sink and the chip 10, neither of them will move, ensuring the consistency of their assembly and the welding and fixing effect.

[0058] like Figure 9 and Figure 10 As shown, in this embodiment, the heating platform 9 and the base 1 have the same cross-sectional shape and size to prevent the heating platform 9 from being too large and causing burns to the operator. The heating platform 9 is a mature existing technology, and its specific structure and heating principle will not be described in detail here.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
