Description

Technical Field

[0001] This invention relates to a pressing mechanism, particularly a pressing mechanism for pressing a pressing element onto a substrate. Background Technology

[0002] Existing pressing mechanisms generally use a single airbag design for pressing. However, since the airbag is an elastic body, although it can overcome height differences, its elastic characteristics can easily cause insufficient force to be applied to the substrate when pressing with an airbag, resulting in incomplete bonding between the pressed objects.

[0003] Furthermore, the existing pressing mechanism does not have a support body at the edge of the bearing platform. Therefore, when airbag pressing is performed, the pressure at the edge of the bearing platform is likely to be too heavy, which may cause problems such as poor lamination.

[0004] Therefore, the need to develop a pressing mechanism that can improve upon the deficiencies of the existing technology is one of the problems that need to be solved in this field. Summary of the Invention

[0005] In view of the above problems, the present invention provides a pressing mechanism that helps to solve the problems of incomplete pressing when pressing a single airbag or flat piece onto a substrate due to the height difference gap of the substrate, and the problem of heavy pressure on the edge of the support platform when pressing an airbag.

[0006] The pressing mechanism disclosed in this invention includes a base, a limiting structure, and at least one lifting structure. The base includes a support platform for supporting a substrate. The limiting structure is movably disposed on the base and surrounds the support platform. The lifting structure is correspondingly disposed on the base. The lifting structure is movable relative to the limiting structure and has an initial position and a pressed position. In the initial position, the upper surface of the limiting structure is higher than the substrate. In the pressed position, the lifting structure actuates to adjust the upper surface of the limiting structure to be flush with the substrate.

[0007] The present invention further discloses a pressing mechanism comprising a base, a limiting structure, at least one elastic element, and a pressing element. The base includes a support platform for supporting a substrate. The limiting structure is movably disposed on the base and surrounds the support platform. The elastic element is spaced apart and arranged around the base and the limiting structure. The pressing element is disposed corresponding to the support platform and can be pneumatically or electrically driven. The limiting structure is movable relative to the pressing element and has an initial position and a pressed position. In the initial position, the upper surface of the limiting structure is higher than the substrate. In the pressed position, the pressing element pushes the limiting structure so that the upper surface of the limiting structure is flush with the substrate.

[0008] The present invention further discloses a pressing mechanism comprising a base and a pressing element. The base includes a support platform for supporting a substrate. The pressing element includes an inflatable airbag and an intermediate layer. The inflatable airbag is disposed corresponding to the support platform. The intermediate layer is adhesively bonded to the inflatable airbag, and the intermediate layer presses the substrate through the inflatable airbag.

[0016] The following embodiments describe in detail the features and advantages of the present invention, the content of which is sufficient to enable any person skilled in the art to understand the technical content of the present invention and to implement it accordingly. Furthermore, based on the disclosure, claims, and drawings in this specification, any person skilled in the art can easily understand the present invention. The following embodiments further illustrate the points of the present invention in detail, but are not intended to limit the scope of the present invention in any way.

[0017] Please refer to Figures 1 to 3 ,in Figure 1 This is a schematic diagram of a pressing mechanism according to an embodiment of the present invention. Figure 2 for Figure 1 A schematic diagram of the limiting structure of the pressing mechanism, and Figure 3 for Figure 1 A schematic diagram of the lifting structure of the pressing mechanism in the pressed position. In this embodiment, the pressing mechanism 1A includes a base 10, a limiting structure 20, an elastic element 30, and a pressing element 40.

[0018] The base 10 includes a support stage 110 for supporting the substrate 11. The upper surface 111 of the support stage 110 may be provided with a negative pressure hole for adsorbing the substrate 11 or a clamp (not shown) for gripping the substrate 11.

[0019] The limiting structure 20 is movably disposed on the base 10 and surrounds the support platform 110 of the base 10. Furthermore, the limiting structure 20 can be disposed on the base 10, thereby surrounding the support platform 110, and the limiting structure 20 can rise or fall relative to the base 10.

[0020] Elastic elements 30 are spaced apart and arranged around the base 10 and the limiting structure 20. Further, the elastic elements 30 are, for example, but not limited to, compression springs or elastically deformable strip-shaped objects, and are disposed between the base 10 and the limiting structure 20. In this embodiment, there are multiple elastic elements 30, and these elastic elements 30 are spaced apart along the circumferential direction of the support platform 110, but the number of elastic elements 30 is not intended to limit the invention.

[0021] The pressing element 40 is disposed on the support platform 110 of the base 10, and the pressing element 40 can be pneumatically driven or electrically driven. Further, the pressing element 40 may include, for example, but not limited to, an inflatable airbag driven by pneumatic pressure or a flattening member driven by electricity. In this embodiment, the pressing element 40 may include an inflatable airbag 410 and an intermediary layer 420. The inflatable airbag 410 is disposed on the support platform 110. The intermediary layer 420 is glued to the inflatable airbag 410, and the inflatable airbag 410 allows the intermediary layer 420 to press against the substrate 11 placed on the support platform 110.

[0022] In this embodiment, the intermediate layer 420 of the pressing element 40 can be made of a soft or hard material. In this embodiment, at least a portion of the intermediate layer can be made of at least one of rubber, silicone, polymer, and metal. Furthermore, at least a portion of the inflatable airbag 410 can be made of at least one of silicone and rubber. Additionally, the intermediate layer 420 of the pressing element 40 can have a thickness of 1 mm to 200 mm, and the inflatable airbag 410 can have a thickness of 1 mm to 10 mm.

[0023] The limiting structure 20 is movable relative to the pressing element 40, and the limiting structure 20 has an initial position and a pressed position. Figure 1 An example is drawn with the limiting structure 20 in its initial position, and Figure 3An exemplary illustration shows the limiting structure 20 in a compressed position. More specifically, the limiting structure 20 can be pushed from its initial position to the compressed position by the interlayer 420 of the pressing element 40. In the initial position, the upper surface 210 of the limiting structure 20 is higher than the substrate 11. In the compressed position, the upper surface 210 of the limiting structure 20 is flush with the substrate 11, and the elastic member 30 is compressed by the limiting structure 20 to store elastic energy. When the pressing element 40 stops pushing the limiting structure 20, the elastic member 30 releases its elastic energy, causing the limiting structure 20 to return to its initial position from the compressed position.

[0024] In this embodiment, the pressing mechanism 1A may further include a reinforcing structure 50 disposed on the lower surface 220 of the limiting structure 20. More specifically, the reinforcing structure 50 is disposed between the base 10 and the limiting structure 20.

[0025] like Figure 3 As shown, substrate 11 can be placed on support stage 110. Substrate 11 is, for example, but not limited to, silicon wafer, circuit board, glass plate or metal plate.

[0026] The inflation of the airbag 410 causes the intermediary layer 420 to press against the substrate 11 and the limiting structure 20. The limiting structure 20 is in a compressed position due to the pressure from the intermediary layer 420 of the pressing element 40. At this time, the upper surface 210 of the limiting structure 20 is within ±1 mm of the substrate 11. More specifically, the intermediary layer 420, through the inflation of the airbag 410, presses against the substrate 11, so that the difference between the upper surface 210 of the limiting structure 20 and the upper surface 100 of the substrate 11 is within ±1 mm. More specifically, the upper surface 210 of the limiting structure 20 in the compressed position is substantially flush with the upper surface 100 of the substrate 11.

[0027] Since the limiting structure 20 supports the pressing element 40, the limiting structure 20 can support the inflatable airbag 410 and the intermediary layer 420, so that when the inflatable airbag 410 pushes the intermediary layer 420, it can more efficiently cover the substrate 11 and fill the gap (not shown) of the substrate 11 with height difference.

[0028] Figures 1 to 3 This invention discloses a pressing mechanism 1A that allows the limiting structure 20 to rise and fall via an elastic element 30 and a pressing element 40, but the invention is not limited thereto. Please refer to... Figures 4 to 6 ,in Figure 4 This is a schematic diagram of a pressing mechanism according to another embodiment of the present invention. Figure 5 for Figure 4 A schematic diagram of the base and limiting structure of the pressing mechanism, and Figure 6 for Figure 4A schematic diagram of the lifting structure of the pressing mechanism in the pressed position. In this embodiment, the pressing mechanism 1B includes a base 10B, a limiting structure 20, a pressing element 40, a lifting structure 60, and a driving device 70.

[0029] The base 10B includes a support stage 110 for supporting the substrate 11. Further, the base 10B may include the support stage 110 and a main body 120B for mounting the support stage 110. The upper surface 111 of the support stage 110 may be provided with negative pressure holes for adsorbing the substrate 11 or with clamps (not shown) for gripping the substrate 11. Additionally, the base 10B may include a plurality of openings 121 formed in the main body 120B, and these openings 121 are spaced apart along the direction of the base 10B. The upper surface 111 of the support stage 110 may be provided with negative pressure holes for adsorbing the substrate 11 or with clamps (not shown) for gripping the substrate 11.

[0030] The lifting structure 60 is correspondingly arranged with the base 10B. Further, the lifting structure 60 can be a connecting rod, and the connecting rod passes through the opening 121 of the base 10B. The driving device 70 is, for example, but not limited to, a servo motor, which is connected to the lifting structure 60 and used to drive the lifting structure 60 to rise or fall. In this embodiment, the number of lifting structures 60 can be multiple, that is, multiple connecting rods respectively corresponding to multiple openings 121 of the base 10B, but the present invention is not limited thereto.

[0031] The limiting structure 20 is movably disposed on the lifting structure 60, and the limiting structure 20 surrounds the support platform 110 of the base 10. Furthermore, the driving device 70 can drive the lifting structure 60 and the limiting structure 20 to rise or fall together relative to the base 10.

[0032] The pressing element 40 is disposed on the support platform 110 of the base 10, and the pressing element 40 can be pneumatically driven or electrically driven. Further, the pressing element 40 may include, for example, but not limited to, an inflatable airbag driven by pneumatic pressure or a flat, electrically driven plate-shaped flattening member. In this embodiment, the pressing element 40 may include an inflatable airbag 410 and an interlayer 420. For a detailed description of the pressing element 40, please refer to the corresponding... Figures 1 to 3 The previous content will not be repeated here.

[0033] The lifting structure 60 can move relative to the limiting structure 20, and the lifting structure 60 has an initial position and a pressure position. Figure 4 An example is drawn with the lifting structure 60 in its initial position, and... Figure 6An example is shown of the lifting structure 60 in the pressed position. Furthermore, the lifting structure 60 can be driven by the driving device 70 to move from the initial position to the pressed position, or to reset from the pressed position to the initial position. In the initial position, the upper surface 210 of the limiting structure 20 is higher than the substrate 11. In the pressed position, the lifting structure 60 actuates such that the upper surface 210 of the limiting structure 20 is flush with the substrate 11.

[0034] like Figure 6 As shown, substrate 11 can be placed on support platform 110. When drive device 70 drives lifting structure 60 to descend to the pressure position, inflatable airbag 410 expands, causing interlayer 420 to push substrate 11 and limiting structure 20. At this time, due to the action of lifting structure 60, the upper surface 210 of limiting structure 20 is adjusted so that it differs from substrate 11 by within ±1mm. More specifically, the difference between the upper surface 210 of limiting structure 20 and the upper surface 100 of substrate 11 is within ±1mm. More precisely, when lifting structure 60 is in the pressure position, the upper surface 210 of limiting structure 20 and the upper surface 100 of substrate 11 are substantially flush.

[0035] In summary, the pressing mechanism disclosed in this invention, due to the limiting structure supporting the pressing element, can support the inflatable airbag and the intermediate layer, allowing the inflatable airbag to more efficiently cover the gaps between the substrate height differences when pushing the intermediate layer. Furthermore, the pressing element, comprising the inflatable airbag and the intermediate layer, not only improves the performance of substrates with varying heights but also effectively fills the gaps between substrates with different heights, thereby increasing the number of uses of the pressing element.
