Description

Pressing mechanism

The invention relates to a pressing mechanism, in particular to a pressing mechanism for pressing a pressing element onto a substrate.

Conventional press-fit mechanisms generally use a single airbag design for press-fitting. However, since the airbag is an elastic body, although it can overcome the height difference, its elastic characteristics can easily cause insufficient force applied to the substrate when the airbag is pressed, resulting in incomplete bonding between the pressed objects.

Furthermore, the edge of the support platform of the conventional press-fitting mechanism is not provided with a support body. Therefore, when the airbag is pressed, it is easy to cause a heavy pressure on the edge of the support platform, which may cause related problems such as poor lamination.

Therefore, it is necessary to develop a compression mechanism that can improve the above-mentioned known technical deficiencies, which is one of the problems that need to be solved in this field.

In view of the above problems, the present invention provides a pressing mechanism that helps to solve the problem that when a single airbag or flat piece is pressed on a substrate by the existing pressing mechanism, the substrate has a height difference gap, which easily causes incomplete pressing and when the airbag is pressed, it is easy to cause heavy pressure on the edge of the support platform.

The compression mechanism disclosed in the present invention includes a base, a limiting structure and at least one lifting structure. The base includes a supporting platform for supporting a substrate. The limiting structure is movably arranged on the base, and the limiting structure surrounds the supporting platform. The lifting structure is arranged corresponding to the base. The lifting structure can move relative to the direction of the limiting structure and has an initial position and a compressed position. In the initial position, an upper surface of the limiting structure is higher than the substrate. In the compressed position, the lifting structure is actuated to adjust the upper surface of the limiting structure to be flush with the substrate.

The new type also discloses a pressing mechanism including a base, a limiting structure, at least one elastic member and a pressing element. The base includes a supporting platform for supporting a substrate. The limiting structure is movably disposed on the base, and the limiting structure surrounds the supporting platform. The elastic member is disposed between the base and the limiting structure at intervals. The pressing element is disposed corresponding to the supporting platform, and the pressing element can be driven by air pressure or electricity. The limiting structure can move relative to the direction of the pressing element and has an initial position and a pressed position. In the initial position, an 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.

The pressing mechanism disclosed in the present invention further comprises a base and a pressing element. The base comprises a support platform for supporting a substrate. The pressing element comprises an inflatable airbag and an intermediate layer. The inflatable airbag is arranged corresponding to the support platform. The intermediate layer is glued to the inflatable airbag, and the intermediate layer pushes the substrate through the inflatable airbag.

The following embodiments further illustrate the viewpoints of the new invention in detail, but do not limit the scope of the new invention by any viewpoint.

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

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

The limiting structure 20 is movably disposed on the base 10, and the limiting structure 20 surrounds the supporting platform 110 of the base 10. Further, the limiting structure 20 can be disposed on the base 10, thereby surrounding the supporting platform 110, and the limiting structure 20 can rise or fall relative to the base 10.

The elastic member 30 is disposed between the base 10 and the limiting structure 20 at intervals around the base 10. Specifically, the elastic member 30 is, for example but not limited to, a compression spring or a strip-shaped object capable of elastic deformation, and the elastic member 30 is disposed between the base 10 and the limiting structure 20. In this embodiment, there are a plurality of elastic members 30, and these elastic members 30 are disposed at intervals along the circumferential direction of the support platform 110, but the number of the elastic members 30 is not intended to limit the present invention.

The pressing element 40 is disposed corresponding to the support platform 110 of the base 10, and the pressing element 40 can be driven by air pressure or electricity. Further, the pressing element 40 includes, for example but not limited to, an inflatable airbag driven by air pressure or a flat plate-shaped flattening member driven by electricity. In this embodiment, the pressing element 40 may include an inflatable airbag 410 and an intermediate layer 420. The inflatable airbag 410 is disposed corresponding to the support platform 110. The intermediate layer 420 is glued to the inflatable airbag 410, and the inflatable airbag 410 can enable the intermediate layer 420 to push the substrate 11 placed on the support platform 110.

In the present embodiment, the intermediate layer 420 of the pressing element 40 may be a soft material or a hard material. In the present embodiment, at least a portion of the intermediate layer may be made of at least one of rubber, silicone, polymer and metal materials. In addition, at least a portion of the inflatable airbag 410 may be made of at least one of silicone and rubber materials. In addition, the intermediate layer 420 of the pressing element 40 may have a thickness of 1 millimeter (mm) to 200 mm, and the inflatable airbag 410 may have a thickness of 1 mm to 10 mm.

The limiting structure 20 can move relative to the direction of the pressing element 40, and the limiting structure 20 has an initial position and a compressed position. FIG. 1 exemplarily illustrates the limiting structure 20 in the initial position, and FIG. 3 exemplarily illustrates the limiting structure 20 in the compressed position. Further, the limiting structure 20 can be pushed by the intermediate layer 420 of the pressing element 40 to move from the initial position to the compressed position. 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 elasticity. When the pressing element 40 no longer presses the limiting structure 20 , the elastic member 30 releases its elasticity, so that the limiting structure 20 returns from the pressed position to the initial position.

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. Specifically, the reinforcing structure 50 is disposed between the base 10 and the limiting structure 20.

As shown in FIG. 3 , a substrate 11 may be placed on a carrier 110 . The substrate 11 may be, for example but not limited to, a silicon wafer, a circuit board, a glass plate or a metal plate.

The inflated airbag 410 expands so that the intermediate layer 420 pushes the substrate 11 and the limiting structure 20. The limiting structure 20 is in a compressed position due to being pushed by the intermediate layer 420 of the pressing element 40. At this time, the upper surface 210 of the limiting structure 20 is within ±1 mm from the substrate 11. More specifically, the intermediate layer 420 pushes the substrate 11 through the inflated airbag 410, so that the upper surface 210 of the limiting structure 20 and the upper surface 100 of the substrate 11 are 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.

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

FIG. 1 to FIG. 3 disclose a compression mechanism 1A that allows the limit structure 20 to be lifted and lowered through an elastic member 30 and a pressing element 40, but the present invention is not limited thereto. Please refer to FIG. 4 to FIG. 6, wherein FIG. 4 is a schematic diagram of a compression mechanism according to another embodiment of the present invention, FIG. 5 is a schematic diagram of a base and a limit structure of the compression mechanism of FIG. 4, and FIG. 6 is a schematic diagram of the lifting structure of the compression mechanism of FIG. 4 in a compressed position. In this embodiment, the compression mechanism 1B includes a base 10B, a limit structure 20, a pressing element 40, a lifting structure 60, and a driving device 70.

The base 10B includes a support table 110 for supporting the substrate 11. Specifically, the base 10B may include the support table 110 and a main body 120B on which the support table 110 is disposed. The upper surface 111 of the support table 110 may be provided with a negative pressure hole for adsorbing the substrate 11 or a clamp (not shown) for clamping the substrate 11. In addition, the base 10B may further include a plurality of openings 121 formed in the main body 120B, and these openings 121 are arranged at intervals along the direction of the base 10B. The upper surface 111 of the support table 110 may be provided with a negative pressure hole for adsorbing the substrate 11 or a clamp (not shown) for clamping the substrate 11.

The lifting structure 60 is disposed corresponding to the base 10B. Specifically, the lifting structure 60 may 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 is used to drive the lifting structure 60 to rise or fall. In this embodiment, the number of the lifting structures 60 may be multiple, that is, multiple connecting rods correspond to multiple openings 121 of the base 10B, but the present invention is not limited thereto.

The limiting structure 20 is movably disposed on the lifting structure 60, and the limiting structure 20 surrounds the supporting 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 relative to the base 10.

The pressing element 40 is disposed corresponding to the support platform 110 of the base 10, and the pressing element 40 can be driven by air pressure or electricity. Further, the pressing element 40 includes, for example but not limited to, an inflatable airbag driven by air pressure or a flat plate-shaped flattening member driven by electricity. In this embodiment, the pressing element 40 can include an inflatable airbag 410 and an intermediate layer 420. For the specific description of the pressing element 40, reference can be made to the previous contents corresponding to Figures 1 to 3, and no further description is given here.

The lifting structure 60 can move in a direction relative to the limiting structure 20, and the lifting structure 60 has an initial position and a compressed position. FIG. 4 exemplarily illustrates the lifting structure 60 in the initial position, and FIG. 6 exemplarily illustrates the lifting structure 60 in the compressed position. Furthermore, the lifting structure 60 can be driven by the driving device 70 to move from the initial position to the compressed position, or to return from the compressed 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 compressed position, the lifting structure 60 is actuated so that the upper surface 210 of the limiting structure 20 is flush with the substrate 11.

As shown in FIG6 , the substrate 11 can be placed on the support platform 110. When the driving device 70 drives the lifting structure 60 to descend to the pressure position, the inflatable airbag 410 expands so that the intermediate layer 420 pushes the substrate 11 and the limiting structure 20. At this time, due to the operation of the lifting structure 60, the upper surface 210 of the limiting structure 20 is adjusted to be within ±1 mm of the substrate 11. More specifically, 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, when the lifting structure 60 is in the pressure position, the upper surface 210 of the limiting structure 20 is substantially flush with the upper surface 100 of the substrate 11.

In summary, according to the compression mechanism disclosed in the present invention, since the limiting structure supports the pressing element, the limiting structure can support the inflatable airbag and the intermediate layer, so that the inflatable airbag can more efficiently cover the gap between the height differences of the substrates when pushing the intermediate layer. In addition, the pressing element includes the inflatable airbag and the intermediate layer, which not only improves the substrate corresponding to the height difference, but also effectively fills the gap between the height difference substrates, and improves the number of times the pressing element can be used.

Anyone skilled in the relevant art may make some changes to the shape, structure, features and spirit described in the scope of application of the present invention without departing from the spirit and scope of the present invention.
