[0030] The present invention will be further described in detail below with reference to specific embodiments:

[0031] like Figure 1 As shown, an integrated dual-purpose chip mounting and rolling mechanism is located downstream of the feeding mechanism. It is used to roll the material strip after chip mounting, so that the chip or heat sink is firmly attached to the material strip.

[0032] The rolling mechanism includes a support platform 2 and a rolling assembly 1. A chip platform 4 is detachably installed on the top of the support platform 2. The rolling assembly 1 includes a roller 11. The rolling assembly 1 moves under the action of the first driving member 3, so that the roller 11 moves to align with the support platform 2 and moves along a preset track to roll and press the chip onto the material strip, so that the chip is firmly attached.

[0033] See attached document Figure 2 As shown, when the chip platform 4 is disassembled, the bottom support platform 2 serves as a workbench to carry the material strip. The rolling assembly 1 moves under the action of the first driving component 3, causing the roller 11 to move and align with the support platform 2, and causing the roller 11 to roll and move along a preset trajectory on the surface of the support platform 2 to roll the flexible heat sink.

[0034] The support platform 2 is modular and detachable, allowing for flexible position adjustment and quick replacement of products of different specifications.

[0035] Specifically, the first driving element 3 includes a two-dimensional module unit 31 and an action driving unit 32.

[0036] The roller 11 is mounted on the two-dimensional module unit 31 via the support member 12. The two-dimensional module unit 31 drives the roller 11 to move in the vertical and horizontal directions, positioning the roller 11 on a preset track. The motion drive unit 32 uses a telescopic cylinder to drive the roller 11 to move along the preset track to roll the material strip.

[0037] See attached document Figure 2 As shown, a second driving component 5 is provided at the bottom of the support platform 2. The second driving component 5 is configured as a lifting driving component, and exemplarily, the lifting driving component is a slide cylinder. The support platform 2 is detachably connected to the driving end of the second driving component 5. With the movement and cooperation of the two-dimensional module unit 31 and the second driving component 5, the distance between the support platform 2 and the roller 11 is adjusted.

[0038] On the support platform 2, a flexible heat sink is reattached to the strip with the chip attached. To avoid damage to the chip from repeated compression, a mounting groove 20 is opened on the support platform. The mounting groove 20 is long and narrow. The strip is laid flat on the support platform 2, and the chip on the strip is aligned with the opening of the mounting groove 20, suspending the area of ​​the strip with the chip attached, thus reducing the pressure on the chip.

[0039] See attached document Figure 4 As shown, the area where the mounting groove 20 is located on the surface of the support platform 2 is the working area 21. The padding area 22 is set around the working area 21. Flexible padding material 23 is covered on the surface of the padding area 22 to support the flexible heat sink, especially the edge of the groove and the edge of the support platform, to reduce the deformation of the flexible heat sink.

[0040] like Figure 4 As shown, the flexible pad 23 is disposed on both sides of the groove opening of the mounting groove 20, which is suitable for cases where the size of the flexible heat sink is small.

[0041] like Figure 5 As shown, the flexible pad 23 is placed in the mounting groove 20. In addition to buffering the chip and reducing damage and deformation, it provides support for the edge gaps and reduces the deformation of the flexible heat sink caused by the edge of the groove.

[0042] In addition, flexible padding material 23 is simultaneously provided on the surface of the placement trough 20 and both sides of the trough opening.

[0043] The flexible pad 23 is in sheet form and is made of one or more composite materials including rubber, silicone, polyurethane, foam materials and bio-based flexible materials.

[0044] Specifically, a mounting hole 24 is provided in the support platform 2, and a pressure sensor is installed in the mounting hole 24 to monitor the downward pressure of the roller 11 on the chip platform 4 or the support platform 2.

[0045] See attached document Figure 3As shown, the roller 11 is connected to the pressure regulating unit 13 via the support member 12. The pressure regulating unit 13 applies pressure to the bottom roller 11. The pressure regulating unit 13 includes an adjusting head 131. The adjusting head 131 is equipped with a spring 133 via a pressure rod 132. The bottom of the spring 133 is installed inside the support member 12.

[0046] Furthermore, an observation window (not shown in the attached figure) is provided on the assembly plate of the support component 2, which can directly display the rolling pressure value. The rolling pressure can be calculated based on the spring compression and the spring elastic coefficient. When the spring is fatigued, the pressure instability can be detected in time and dealt with promptly. Therefore, through the cooperation of the pressure sensor and the spring, the pressure can be fed back in real time to ensure product quality.

[0047] The adjustment head 131 rises and falls, and the spring 133 is compressed by the pressure rod 132, which drives the support 12 to rise and fall, changing the magnitude of the positive pressure of the bottom roller 11 on the chip platform 4 or the support platform 2.

[0048] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore, all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
