Description

Technical Field

[0001] This invention applies to the field of 3D packaging technology, and particularly relates to a novel MLCC peeling mechanism. Background Technology

[0002] With the rapid development of domestically produced high-end chips, capacitors can be embedded in silicon interposers or substrates in advanced 3D packaging (such as 2.5D / 3D heterogeneous integration) to reduce parasitic effects and improve power integrity. Multilayer ceramic capacitors (MLCCs), as core passive components of electronic devices, are widely used in smartphones, new energy vehicles, and other terminal products due to their advantages of small size, large capacitance, and high reliability. In their production process, the separation process is one of the key steps to ensure product quality. This process is mainly used to separate the ceramic film from the substrate, the waste edge of the chip block from the effective chip area, or the device from the substrate, directly affecting the MLCC stacking accuracy, structural integrity, and electrical performance.

[0003] Current peeling methods have significant drawbacks: traditional manual peeling is inefficient, labor-intensive, and prone to damage such as ceramic diaphragm cracking and electrode layer detachment due to improper force application; thermal debonding peeling is prone to product adhesion and powder residue, posing safety hazards and easily damaging devices; mechanical peeling mechanisms often lack sufficient motion precision, easily leading to diaphragm adhesion and misalignment, reducing production yield. As MLCCs develop towards smaller sizes and higher layer counts, the requirements for peeling precision, efficiency, and non-destructiveness have increased significantly. Existing peeling mechanisms can no longer meet the demands of large-scale, high-precision production. Therefore, developing efficient, precise, and non-destructive MLCC peeling mechanisms has become an urgent need for the industry. If a new type of MLCC peeling mechanism can be designed with a simple structure, using rollers instead of traditional sharp corners for peeling, achieving high peeling precision and low peeling resistance, the above problems can be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a new type of MLCC peeling mechanism with simple structure, roller instead of traditional sharp corners for peeling, high peeling accuracy and low peeling resistance.

[0005] The technical solution adopted in this invention is as follows: This invention includes a peeling plate assembly and a peeling roller assembly. The peeling plate assembly includes a support frame, a conveying module, and a peeling platform. The conveying module is disposed on the support frame. The peeling platform is slidably engaged with the support frame via a slide rail. The movable end of the conveying module is connected to the peeling platform. The strip product is engaged with the rolling end of the peeling roller assembly via the conveying module.

[0006] Furthermore, the roller assembly includes a mounting base, rolling bearings, and a stripping roller shaft. Two sets of mounting bases are respectively mounted on a support frame, and two sets of rolling bearings are respectively mounted on two sets of mounting bases. The two ends of the stripping roller shaft are rotatably engaged with the two sets of rolling bearings.

[0007] Furthermore, a retaining ring is provided between the stripping roller shaft and the two sets of rolling bearings.

[0008] Furthermore, the peeling platform is provided with a peeling tip at its end, and the product film belt end of the material strip cooperates with several rollers below the peeling platform through the peeling tip and the peeling roller shaft.

[0009] Furthermore, the support frame is equipped with several grating rulers, which are in sensing engagement with the sensing end of the stripping platform.

[0010] Furthermore, the mounting base is provided with several adjustment holes, and the mounting base is connected to the support frame through several adjustment screws and several adjustment holes.

[0011] Furthermore, the highest point of the peeling roller is at the same height as the peeling tip.

[0012] Furthermore, the peeling platform is provided with a plurality of adsorption holes, which are adsorbed and engaged with the film end of the material strip product.

[0013] The beneficial effects of this invention are: This invention innovatively adds a peeling roller in front of the peeling platform, and the roller replaces the traditional sharp corner for peeling. The two ends of the roller are supported by deep groove ball bearings. The roller rotates together during peeling, reducing peeling resistance. The position of the peeling roller can be finely adjusted up, down, left and right. Attached Figure Description

Detailed Implementation

[0015] like Figures 1 to 4As shown, in this embodiment, the present invention includes a peeling plate assembly 1 and a peeling roller assembly 2. The peeling plate assembly 1 includes a support frame 11, a conveying module 12, and a peeling platform 13. The conveying module 12 is mounted on the support frame 11, and the peeling platform 13 is slidably engaged with the support frame 11 via a slide rail 14. The movable end of the conveying module 12 is connected to the peeling platform 13, and the strip product 3 engages with the rolling end of the peeling roller assembly 2 via the conveying module 12. Therefore, the PET film, having the desired product film printed on it through casting, needs to be cut and then separated from the PET by the peeling plate. A set of peeling roller assemblies 2 is installed in front of the peeling platform 13, using rollers instead of traditional sharp corners for peeling. The conveying module 12 is driven by a gantry double linear motor, resulting in higher movement accuracy.

[0016] like Figures 1 to 4 As shown, in this embodiment, the roller assembly 2 includes a mounting base 21, rolling bearings 22, and a stripping roller shaft 23. Two sets of mounting bases 21 are respectively mounted on the support frame 11, and two sets of rolling bearings 22 are respectively mounted on the two sets of mounting bases 21. The two ends of the stripping roller shaft 23 are rotatably engaged with the two sets of rolling bearings 22. Therefore, the stripping roller 23 is mounted on the two sets of mounting bases 21, with a certain installation distance between the stripping roller 23 and the stripping platform 13. Too close a distance would hinder the adjustment of the roller shaft's parallelism, while too far a distance would affect the stripping effect. The rolling bearings 22 are low-friction bearings to further reduce the resistance of the stripping roller. The stripping roller shaft 23 and the rolling bearings 22 are precisely matched. One set of stripping rollers requires four rolling bearings, increasing the radial force limit of the stripping roller.

[0017] like Figure 4 As shown, in this embodiment, a retaining ring 24 is provided between the peeling roller shaft 23 and the two sets of rolling bearings 22. Therefore, the retaining ring 24 eliminates the axial clearance between the rolling bearings 22 and the peeling roller shaft 23, preventing the peeling roller 23 from axially shifting during rotation.

[0018] like Figure 2 As shown, in this embodiment, the peeling platform 13 is provided with a peeling tip 15 at its end. The film end of the strip product 3 cooperates with several rollers 4 below the peeling platform 13 through the peeling tip 15 and the peeling roller shaft 23. Therefore, peeling is performed by replacing the traditional sharp corner with a roller shaft, reducing peeling resistance.

[0019] like Figure 2As shown, in this embodiment, the support frame 11 is provided with a plurality of grating rulers 5, which are in sensing engagement with the sensing end of the peeling platform 13. Therefore, the plurality of grating rulers 5 are used to position the movement of the peeling platform 13.

[0020] like Figure 4 As shown, in this embodiment, the mounting base 21 is provided with a plurality of adjustment holes 25, and the mounting base 21 is connected to the support frame 11 by a plurality of adjustment screws and a plurality of adjustment holes 25. Therefore, the plurality of adjustment holes 25 can adjust the top of the peeling roller shaft 23 to be flush with the peeling platform 13, allowing the film to flow smoothly into the upper part of the peeling roller shaft 23.

[0021] like Figure 4 As shown, in this embodiment, the highest point of the peeling roller 23 is at the same height as the peeling tip 15. Therefore, having the top of the peeling roller 23 flush with the peeling platform 13 allows the film to flow more smoothly into the upper part of the peeling roller 23, resulting in a better peeling effect.

[0022] like Figure 2 As shown, in this embodiment, the peeling platform 13 is provided with a plurality of adsorption holes 16, which are adsorbed and engaged with the film end of the strip product 3. Therefore, the plurality of adsorption holes 16 adsorb the strip product 3, thereby enabling the subsequent peeling operation.

[0023] The working principle of this invention is as follows: The desired product film is cast and printed on the PET film. After being cut, it flows into the peeling platform 13. Several adsorption holes 16 adsorb the strip product 3 and drive it to the peeling position. The external winding mechanism is activated, and the strip product 3 slides on the peeling platform 13. The peeling roller 23 achieves a high-efficiency peeling effect.

[0024] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
