Description

Technical Field

[0001] The utility model is applied to the technical field of product pressing, and particularly relates to a contoured, highly fitting, and anti-stripping pressing head. Background Art

[0002] With the rapid development of the smartphone industry, demand for battery management systems has skyrocketed, making them a critical component for ensuring device performance and safety. The battery management unit (BMU) plays a core role within a mobile phone, precisely regulating the battery's charge and discharge processes and monitoring key indicators such as temperature and voltage to maintain battery stability, reliability, and high efficiency. In this context, performance and reliability testing of the BMU's subsystem, the BMU-SIP (System in Package), a core building block, has become particularly important to meet diverse market demands and demanding application conditions. Technological advancements have driven the continuous evolution of electronic packaging, enabling the BMU-SIP to shrink to an extremely small size. However, this has also created unprecedented testing challenges for manufacturers. Highly integrated functional modules require more rigorous testing procedures, and the differences between the BMU-SIP's pre- and post-packaging states further complicate testing. This is especially true of unpackaged BMU-SIPs, whose structure is more fragile and prone to deformation under pressure. Conventional testing methods for these products typically use POM indenters for component contact and product pressing. However, due to its Rockwell hardness of approximately 90, this can leave indentations on the product surface during testing, posing a significant risk. On the other hand, if one were to consider using silicone as the indenter to circumvent the hardness issue, while the softness of silicone helps protect the product from damage, its tight adhesion to the product surface presents another challenge: when the indenter is lifted after the test, the silicone can easily adhere to the product and lift it, undoubtedly another threat to product integrity. This problem could be solved by designing a simple, contoured, high-contact, anti-lifting indenter that uses elastic limiting to prevent excessive contact with the product and sandblasting to increase the surface roughness of the silicone indenter to prevent adhesion. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a contoured, highly fitting, and anti-lifting pressure head with a simple structure, which avoids excessive contact of the pressure head with the product by elastic limiting and increases the surface roughness of the silicone pressure head by sandblasting to prevent adhesion of the product.

[0004] The technical solution adopted by the present invention is: the present invention includes a pressure plate, a pressure block and a flexible pressure head module, the flexible pressure head module is arranged between the pressure block and the pressure plate, the flexible pressure head module includes a pressure head mounting seat and a flexible pressure head, the pressure block is floatingly connected to the pressure head mounting seat, a pressure head limiting opening is provided in the middle of the pressure plate, the pressure head mounting seat is limitedly matched with the pressure head limiting opening, and the flexible pressure head is matched with the product pressing end at the lower end of the pressure plate through the pressure head limiting opening.

[0005] Furthermore, a pressure head mounting groove is provided at the lower end of the pressure head mounting seat, the upper end of the flexible pressure head is limitedly matched with the pressure head mounting groove, and the pressure head mounting seat is connected to the flexible pressure head through a plurality of fixing pins.

[0006] Furthermore, the pressing block is floatingly connected to the upper end of the pressing head mounting seat through a plurality of equal height screws and a plurality of floating springs.

[0007] Furthermore, a plurality of positioning pins are provided on the upper end of the pressure plate, and the lower end of the pressure block is positioned and matched with the plurality of positioning pins.

[0008] Furthermore, the pressing block is connected to the pressing plate via a plurality of fixing screws.

[0009] Furthermore, a plurality of mounting holes are provided on the upper end of the pressing block.

[0010] Furthermore, the lower end of the flexible pressing head is provided with a plurality of pressing positions, and the plurality of pressing positions cooperate with the pressing end of the product.

[0011] Furthermore, a sandblasting layer is provided on the surface of the flexible pressure head.

[0012] The beneficial effects of the present invention are as follows: This application describes an innovative contoured, high-fitting, anti-lifting silicone indenter solution. This solution tailors the pressing area according to the customer's specific component layout, aiming to perfectly adapt to and effectively protect the delicate components on the BMU-SIP, avoiding any damage during the testing process. In addition, through a unique anti-adhesion design, the problem of adhesion between the silicone material and the component surface is overcome, thereby achieving all-round protection for the components while ensuring that the product deformation is controlled within an extremely strict range of ±500με. At the same time, the modular design enables the replacement of the indenter according to the product size, with strong applicability. The flexible indenter and the indenter mounting seat rely on springs to achieve elastic limit, thereby reducing the vertical tolerance accumulation, ensuring the high positioning accuracy of the flexible indenter installation position, and preventing excessive compression deformation when touching the product. The surface of the silicone indenter is treated with an 800-mesh sandblasting process to increase the surface roughness of the silicone indenter. While maintaining the original advantage of silicone in not abrading the product, it also overcomes the problem of product sticking caused by excessive adhesion. BRIEF DESCRIPTION OF THE DRAWINGS

It can be seen that the flexible pressure head 5 is processed and formed from a silicone material with a hardness calibrated to 70 degrees. The soft properties of silicone are conducive to protecting the product from damage. The pressure head mounting seat 4 and the pressure block 2 rely on springs to achieve elastic limitation, thereby reducing the tolerance accumulation in the vertical direction, ensuring the high positioning accuracy of the installation position of the flexible pressure head 5, and preventing excessive compression deformation when touching the product.

[0018] like Figure 2 and Figure 4 As shown, in this embodiment, the lower end of the pressure head mounting base 4 is provided with a pressure head mounting groove 7, the upper end of the flexible pressure head 5 is limitedly engaged with the pressure head mounting groove 7, and the pressure head mounting base 4 is connected to the flexible pressure head 5 via a plurality of fixing pins 8. Thus, it can be seen that the pressure head mounting base 4 can be quickly replaced by the pressure head mounting groove 7 on the pressure head mounting base 4 to adapt to products of different sizes, and the plurality of fixing pins 8 ensure that the flexible pressure head 5 is evenly stressed as a whole and prevents it from deflecting or falling off.

[0019] like Figures 1 to 3 As shown, in this embodiment, the pressing block 2 is connected to the upper end of the pressing head mounting seat 4 in a floating manner through a plurality of equal height screws 9 and a plurality of floating springs 10. It can be seen that the plurality of floating springs 10 provide the pressing head mounting seat 4 with a downward pressure buffering and resetting effect.

[0020] like Figure 2As shown, in this embodiment, the upper end of the pressure plate 1 is provided with a plurality of positioning pins 11, and the lower end of the pressure block 2 is positioned and matched with the plurality of positioning pins 11. It can be seen that the plurality of positioning pins 11 achieve the precise positioning of the pressure block 2 and the pressure plate 1.

[0024] like Figure 1 and Figure 2 As shown in the figure, in this embodiment, the surface of the flexible pressure head is provided with a sandblasting layer. Thus, the surface roughness of the flexible pressure head 5 made of silicone is increased by applying an 800-mesh sandblasting process.

[0025] The working principle of the present utility model is as follows: during the pressing process, the pressing block 2 drives the flexible pressing head 5 to descend, and the several pressing positions 14 on the flexible pressing head 5 fit with the components to be pressed on the product. The pressing block 2 continues to press down, and the flexible pressing head 5 slides in the pressing head limit port 6. Several floating springs 10 provide a buffering effect to prevent overpressure. After the pressing is completed, the pressing block 2 is reset, and several floating springs 10 drive the flexible pressing head 5 to reset and separate from the product. The product to be tested is replaced, and the above steps are repeated to achieve high-fitting and anti-slip pressing of the product.
