Description

Technical Field

[0001] This utility model relates to a pressurizing device, and more particularly to a pressurizing device having a dry, low-adhesion modified outer layer. Background Technology

[0002] Pressurization devices are common and in-demand processing equipment, and airbag pressurization devices, which use airbags to apply uniform pressure to the material to be pressed, are the pinnacle of pressurization devices. Airbag pressurization devices utilize the property of airbags to inflate upon receiving external air pressure, allowing them to press objects to be pressed. Examples include vacuum pressing of flexible circuit boards, pressure formation of batteries, and vacuum bonding of semiconductors.

[0003] Most airbags are made of silicone, which helps prevent deterioration or deformation in environments such as vacuum due to the material's inherent stability. However, silicone is sticky, and when the airbag is inflated and pressurized during the high-pressure process, it tends to stick to the surface of the object being pressed. Therefore, in (semi-)automatic equipment, an intermediate medium is usually placed between the airbag and the object being pressed to prevent contamination of the airbag equipment or damage to the surface of the object after sticking. However, this intermediate medium is a consumable, which not only increases working hours but also adds to the cost of materials.

[0004] On the other hand, if the object to be pressed can be cleaned later or the surface condition is not a concern, a release agent can be used to help the airbag and the object to be pressed to be demolded, thus saving the cost of the aforementioned intermediate medium. However, the release agent still needs to be replenished regularly, and the release agent will reduce the conductive or anti-slip properties, which will reduce the relevant performance of the object to be pressed.

[0005] In view of the deficiencies in the prior art, this utility model proposes a pressurization device to effectively solve the above problems. Utility Model Content

[0006] The main purpose of this invention is to provide a pressurizing device that uses an airbag with a dry, low-adhesion modified outer layer to avoid the problem of silicone adhesion during the pressing process. It can also solve the cost problem of consumables used in the prior art and avoid the impact of wet release agents on the surface of the object to be pressed.

[0007] This utility model proposes a pressurizing device, which includes: a support base with an opening on its bottom surface; and an airbag fitted onto the support base. The airbag has an elastic bladder layer with a chamber inside. The bladder layer includes: a silicone inner layer; a low-adhesion modified outer layer, partly exposed through the opening; and a permeation transition layer located between the silicone inner layer and the low-adhesion modified outer layer; and an injection element connected to the chamber to inject gas into the chamber, causing the elastic bladder layer to expand and drive the low-adhesion modified outer layer to be exposed through the opening and pressurized against the object to be pressed.

[0008] Preferably, the low-tack modified outer layer is a hand-feel oil-treated layer.

[0009] Preferably, the low-adhesion modified outer layer is a baked-dry layer made by coating the surface of the airbag with a modifier consisting of silicone sealant, kerosene and organic additives.

[0010] Preferably, the shape of the opening is the same as the shape of the pressed surface of the object to be pressed.

[0011] Preferably, the area of ​​the opening is not less than the surface area of ​​the surface to be pressed of the object to be pressed.

[0012] Preferably, the low-adhesion modified outer layer is able to directly adhere to the surface of the object to be pressed.

[0013] Preferably, the low-adhesion modified outer layer is a dry low-adhesion modified layer.

[0014] Preferably, the elastic lining layer is composed of silicone material that can withstand heat baking at at least 150°C.

[0015] Preferably, the device also includes a support platform disposed below the support base to support the object to be pressed facing the opening of the support base.

[0016] Preferably, it also includes an extended baffle wall disposed between the pressurizing device and the support platform and surrounding the object to be pressed, so as to prevent the airbag from protruding along the gap between the pressurizing device and the support platform when it inflates and is pressurized.

[0017] Preferably, a fixing mechanism is also included to maintain the relative position of the pressurizing device and the support platform.

[0018] Preferably, the fixing mechanism includes: a grabber with one end gripping the bottom edge of the support platform; and a movable fixing member that movably fixes the other end of the grabber to the extended retaining wall.

It should be noted that these embodiments are merely representative examples of this utility model and are not intended to limit the scope of implementation or protection of this utility model. The purpose of providing these embodiments is solely to make the disclosure of this utility model more thorough and easier to understand.

[0024] The terminology used in the various embodiments disclosed herein is for the purpose of describing particular embodiments only and is not intended to limit the various embodiments disclosed herein. Unless explicitly indicated otherwise, the singular forms used also include the plural forms. Unless otherwise specified, all terms used in this specification (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments disclosed herein pertain. The foregoing terms (such as those defined in a general dictionary) are to be interpreted as having the same meaning as in the context of the same technical field and are not to be interpreted as having an idealized or overly formal meaning unless explicitly defined in the various embodiments disclosed herein.

[0025] For the pressurizing device 1 disclosed in this utility model, please refer to [link / reference needed]. Figure 1 It includes a support base 10, an airbag 20, and an inflation component 30. The support base 10 has an internal accommodating space and an opening 11 on its bottom surface. The airbag 20 is disposed within the accommodating space of the support base 10 and is secured to the support base 10 without detaching. Therefore, the appearance and shape of the airbag 20 and the support base 10 are not particularly limited, as long as the airbag 20 can be secured within the support base 10 without detaching. The opening 11 on the bottom surface of the support base 10 is for the airbag 20 to be exposed and pressurized when it inflates. Therefore, the size and shape of the opening 11 mainly depend on the area of ​​the pressurization process, and the shape can be designed according to requirements. Generally speaking, a square shape is common.

[0026] The airbag 20 includes an elastic bladder layer 21 with a chamber 210 inside. An inflation element 30 passes through the support 10 and communicates with the chamber 210 of the airbag 20, receiving external air and guiding air into the chamber 210. The bladder layer 21 includes a silicone inner layer 211, a low-adhesion modified outer layer 213, and a permeable transition layer 212 located between the silicone inner layer 211 and the low-adhesion modified outer layer 213. (See [link to relevant documentation]). Figure 2The low-adhesion modified outer layer 213 can be a commonly known hand-feel oil treatment layer, which is a baked-dry layer formed by coating a modifier consisting of silicone glue, kerosene and organic additives onto the surface of the airbag 20 made of silicone material. For example, silicone glue, kerosene and organic additives can be mixed in a ratio of 6:1:3, diluted with three times the amount of toluene, a catalyst can be added after dilution, and the mixture can be sprayed onto the surface of the airbag 20 and then baked at 150°C for about 30 minutes to adhere it, thus forming a dry low-adhesion modified outer layer 213. Therefore, the elastic skin layer 21 is composed of silicone material that can withstand baking at least 150°C. The permeation transition layer 212 located between the silicone inner layer 211 and the low-adhesion modified outer layer 213 has an uneven permeation transition zone during the modification process. Therefore, it integrates the silicone inner layer 211 and the low-adhesion modified outer layer 213, thereby providing better bonding between the silicone inner layer 211 and the modified outer layer 213, as well as interface buffering when the two materials expand.

[0027] When applying this technology to the pressing process, please also refer to [the relevant documentation]. Figure 2-3A The pressurizing device 1 includes a support base 10, an air bladder 20, and an air injection component 30. A support platform 50 is positioned below the support base 10 to support the object 40 to be pressed, directly facing the opening 11 of the support base 10. The support platform 50 can be fixed or movable. Movable platforms can include common vertical, rotary, or horizontal conveying mechanisms, and may even be used in conjunction with robotic arms for gripping; no limitations are imposed here. On the other hand, if the air bladder 20 is inflated for pressurization, it may protrude along the gap between the pressurizing device 1 and the support platform 50, causing damage or uneven pressurization. Therefore, please refer to [further details needed]. Figure 3B An extended baffle 61 can be added between the pressurizing device 1 and the support platform 50. The extended baffle 61 can surround and enclose the area around the object to be pressed 40 to prevent the airbag 20 from being pushed out. The extended baffle 61 can be an additional addition, or it can be an integral design with the support base 10 of the pressurizing device 1 or an integral design with the support platform 50. No particular restrictions are placed here.

[0028] The pressurizing device 1 receives external air pressure from the air injection element 30 connected to the chamber 210 and injects gas into the chamber 210, causing the elastic skin layer 21 of the airbag 20 to expand. This causes the low-adhesion modified outer layer 213 to be exposed from the opening and pressurize the object to be pressed 40 during the pressing process. Furthermore, to prevent the object to be pressed 40 from tilting due to the pressure from the airbag 20 or to change the relative position between the object to be pressed 40 and the airbag 20 during pressurization, a fixing mechanism is designed to maintain the relative position of the pressurizing device 1 and the support platform 50, that is, to maintain their tight fit during the pressurization process. Figure 3BAs shown, a clamping member 63 is connected to the end of the extended retaining wall 61 using a movable fixing member 62. The clamping member 63, with its laterally extended end, can clamp onto the bottom edge of the support platform 50. The movable fixing member 62 can be a pin or bolt, etc., to secure the clamping member 63 in this position. This structure is merely an example to illustrate the illustration; pneumatic or hydraulic methods can also be used for fully automatic clamping.

[0029] Furthermore, to facilitate the pressing process, the shape of the opening 11 of the support 10 can be identical to the shape of the object to be pressed 40, or the area of ​​the opening 11 of the support 10 can be no less than the surface area of ​​the object to be pressed 40. After the pressing process is completed, the pressure can be released through the air injection device 30 (or another pressure relief device can be used) to restore the airbag 20 to its original state. Because the low-adhesion modified outer layer 213 of the airbag is used to contact and pressurize the object to be pressed 40, its low-adhesion characteristics allow for smooth demolding without sticking.

[0030] In summary, this utility model proposes a pressurizing device, in which the airbag includes an elastic bladder layer and an outermost dry, low-stick modified outer layer. Due to its dry and low-stick properties, it can be easily demolded without sticking after the pressing process, eliminating the need for consumables or wet release agents used in the prior art. This not only reduces manufacturing costs and time but also maintains the surface properties of the object to be pressed.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Therefore, all equivalent variations or modifications made in accordance with the features and spirit described in the claims of this utility model should be included within the scope of the claims of this utility model.
