Description

Technical Field

[0001] This utility model relates to the field of copper clad laminate production technology, and in particular to a prepreg packaging device that can effectively prevent prepreg from sticking together. Background Technology

[0002] Prepreg, also known as PP sheet, is one of the main raw materials for the production of copper-clad laminates and multilayer PCBs. Prepreg is mainly composed of resin and reinforcing materials. The reinforcing materials are mainly divided into several types, such as fiberglass cloth, paper-based materials, and composite materials. The resin is in the B-stage structure, which is fluid under temperature and pressure and can quickly cure and complete the bonding process.

[0003] One existing method for packaging and transporting prepregs involves stacking prepregs cut to specifications into a certain number of sheets to form a laminate, then packing the laminate into a sealed bag before transporting it. However, for prepregs with a minimum melt viscosity below a certain value, structural problems such as adhesion can easily arise due to the material's special properties. For example, during stacking, the bottom layers may be compressed or affected by temperature, causing the prepregs to stick together. Moreover, the degree of adhesion varies under different ambient temperatures and pressure levels. Once the prepregs stick together, they become impossible to tear apart, or tearing them may result in severe powder shedding, rendering them unusable. Furthermore, handling during packaging and transportation can easily cause folding and damage to the prepregs, similarly rendering them unusable.

[0004] Currently, the main solutions to the problem of prepreg adhesion include: adjusting the prepreg specifications, adding ice packs to the packaging bag, and controlling the temperature of the transport vehicle. Apart from these methods, there are currently no other more effective solutions. However, these measures are only supplementary and cannot completely solve the problem of prepreg adhesion.

[0005] Therefore, it is necessary to provide a prepreg packaging device that can completely solve the problem of prepreg adhesion, in order to address the aforementioned issues. Utility Model Content

[0006] The purpose of this invention is to provide a prepreg packaging device that can completely solve the problem of prepreg adhesion.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: A prepreg packaging device is provided, suitable for packaging a laminate obtained by stacking multiple prepregs. The prepreg packaging device includes a first support component and a second support component; wherein, the first support component includes a first support plate and a first buffer layer arranged sequentially, the hardness of the first support plate being greater than the hardness of the first buffer layer; the second support component includes a second support plate and a second buffer layer arranged sequentially, the hardness of the second support plate being greater than the hardness of the second buffer layer; the first support component and the second support component are arranged opposite to each other and used to clamp the laminate, and the first buffer layer and the second buffer layer are respectively attached to the two sides of the laminate.

[0008] Preferably, the first support assembly further includes a first isolation sheet, which is disposed on the side of the first buffer layer away from the first support plate; the second support assembly further includes a second isolation sheet, which is disposed on the side of the second buffer layer away from the second support plate; the first isolation sheet and the second isolation sheet are respectively used to adhere to the two sides of the laminate, and the first isolation sheet and the second isolation sheet are used to isolate the first buffer layer, the second buffer layer and the laminate, so as to prevent the impurities generated by the first buffer layer and the second buffer layer from being introduced into the semi-cured sheet of the laminate and affecting the quality.

[0009] Preferably, the dimensions of the first support component and the second support component are both greater than or equal to the dimensions of the laminate, so that when the first support component and the second support component are clamped on both sides of the laminate, a certain gap is formed at the ends of the laminate, which can effectively prevent the laminate from being squeezed during lifting or transportation, thereby avoiding deformation or damage to the semi-cured sheet of the laminate.

[0010] Preferably, both the first support plate and the second support plate are made of hard and lightweight materials. In this way, on the one hand, using the first support plate and the second support plate to support the laminate can effectively prevent damage to the semi-cured sheet of the laminate during transportation and handling. On the other hand, it reduces the overall weight of the packaging, making it easier to handle and transport, and reducing transportation costs.

[0011] Preferably, both the first support plate and the second support plate are metal plates, plastic plates, wood plates or cardboard plates, thus having sufficient rigidity to support the laminate and effectively preventing damage to the semi-cured sheets of the laminate during transportation and handling.

[0012] Preferably, both the first support plate and the second support plate are hollow or have a honeycomb structure inside, thereby reducing weight, facilitating lifting and transportation, and reducing transportation costs.

[0013] Preferably, both the first support plate and the second support plate are corrugated sheets. While ensuring rigidity, corrugated sheets have a lighter weight, making them easier to handle and transport, thus reducing transportation costs.

[0014] Preferably, both the first buffer layer and the second buffer layer have a honeycomb structure inside, which can absorb heat, avoid heat concentration, and buffer pressure, effectively solving the problem of prepreg adhesion caused by temperature rise or pressure from stacked prepregs.

[0015] Preferably, the first buffer layer and the second buffer layer are each independently selected from a foam layer, a sponge layer, a foam plastic layer, a cotton layer, a fiber filler layer, a recycled paper layer, or a polyester fiber layer. The aforementioned materials all have good heat absorption and pressure buffering capabilities, which can effectively prevent heat concentration and reduce pressure, thereby effectively solving the problem of prepreg adhesion caused by temperature rise or pressure from prepreg stacking.

[0016] Preferably, both the first and second isolation sheets are plastic films, which are used to isolate the laminate and prevent the first and second buffer layers from causing internal impurities to the semi-cured sheet of the laminate.

[0017] Preferably, the first and second separators can be plastic sheets made of any material such as polycarbonate (PC), polypropylene (PP), polyethylene terephthalate (PET), or polyvinyl chloride (PVC).

[0018] Preferably, the prepreg packaging device further includes a packaging bag for containing the package body formed by the first support component and the second support component clamping the laminate, thereby achieving sealing and fixing of the package body and facilitating handling and transportation.

[0019] Preferably, the packaging bag is vacuum-sealed to seal and fix the first support component, the laminate, and the second support component, which makes it easier to handle and transport.

[0020] Preferably, the minimum melt viscosity of the prepreg is ≤150 Pa·s (e.g., it can be 5 Pa·s, 10 Pa·s, 20 Pa·s, 30 Pa·s, 40 Pa·s, 50 Pa·s, 60 Pa·s, 70 Pa·s, 80 Pa·s, 90 Pa·s, 100 Pa·s, 110 Pa·s, 120 Pa·s, 130 Pa·s or 140 Pa·s). Prepregs within this melt viscosity range are easily affected by temperature, pressure, etc., and may stick together. Therefore, the prepreg encapsulation device is used to encapsulate the prepregs to solve the problem of prepreg sticking caused by temperature rise or stacking pressure.

[0021] Compared with existing technologies, the prepreg packaging device of this invention features a first support component and a second support component to clamp a laminate formed by stacking multiple prepreg sheets. The first support component has a first support plate and a first buffer layer arranged sequentially, with the first support plate having a higher hardness than the first buffer layer and the first buffer layer being flexible. Similarly, the second support component has a second support plate and a second buffer layer arranged sequentially, with the second support plate having a higher hardness than the second buffer layer and the second buffer layer being flexible. In use, the first and second buffer layers are positioned opposite each other and respectively adhere to the two sides of the laminate. Because the first and second buffer layers can absorb heat, preventing heat concentration, and buffer pressure, they effectively solve the problem of prepreg adhesion caused by temperature rise or pressure from stacked prepreg sheets. Furthermore, using the rigid first and second support plates to support the entire laminate effectively prevents damage to the prepreg sheets during transportation and handling.

[0025] Embodiments of the present invention will now be described with reference to the accompanying drawings, in which similar element reference numerals represent similar elements. It should be noted that the directional descriptions involved in the present invention, such as up, down, left, right, front, and back, indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the technical solutions of this application or / and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first," "second," etc., described are only used to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0026] Combination Figure 1-Figure 3As shown, the prepreg packaging device 100 provided by this utility model is suitable for packaging a laminate 200 obtained by stacking multiple prepregs 210. The prepregs 210 are commercially available, and the number of prepregs 210 is not specifically limited. In this utility model, the prepreg packaging device 100 is particularly suitable for packaging prepregs 210 with a minimum melt viscosity ≤150 Pa·s, such as prepregs 210 with viscosities of 5 Pa·s, 10 Pa·s, 20 Pa·s, 30 Pa·s, 40 Pa·s, 50 Pa·s, 60 Pa·s, 70 Pa·s, 80 Pa·s, 90 Pa·s, 100 Pa·s, 110 Pa·s, 120 Pa·s, 130 Pa·s, or 140 Pa·s. Prepreg 210 with a minimum melt viscosity ≤150 Pa·s is prone to adhesion when exposed to temperature, pressure, etc., rendering it unusable. The prepreg encapsulation device 100 of this application effectively solves the adhesion problem caused by temperature increases or pressure from stacked prepreg 210. Of course, the prepreg encapsulation device 100 is not limited to encapsulating easily adhesive prepreg 210; it can also be used to encapsulate other easily adhesive sheets.

[0027] It should be noted that one method for obtaining the minimum melt viscosity of the prepreg 210 is as follows: The rheological curve of the prepreg adhesive layer sample is tested using an Anton Paar MCR302 rheometer, with the test temperature range set to 100-180℃ and the heating rate at 3℃ / min. After the test, the minimum melt viscosity value appearing between 100-180℃ is read from the corresponding rheological curve.

[0028] More specifically, the prepreg system in this invention can be selected from any one or a combination of at least two of the following: epoxy resin adhesive system, cyanate ester resin adhesive system, polyphenylene ether resin adhesive system, maleimide resin adhesive system, hydrocarbon resin adhesive system, acrylate resin adhesive system, polyimide resin adhesive system, silicone resin adhesive system, or polyester resin adhesive system.

[0029] The following will continue to combine Figure 1-Figure 3As shown, in one embodiment of this utility model, the prepreg packaging device 100 includes a first support component 110 and a second support component 120, the dimensions of which are both greater than or equal to the dimensions of the laminate 200. Specifically, the first support component 110 includes a first support plate 111 and a first buffer layer 112 arranged sequentially. The hardness of the first support plate 111 is greater than the hardness of the first buffer layer 112, and the first buffer layer 112 has a certain degree of flexibility. Correspondingly, the second support component 120 includes a second support plate 121 and a second buffer layer 122 arranged sequentially. The hardness of the second support plate 121 is greater than the hardness of the second buffer layer 122, and the second buffer layer 122 has a certain degree of flexibility. When encapsulating the laminate 200, the first support component 110 and the second support component 120 are respectively disposed on both sides of the laminate 200 to clamp the laminate 200, and the first buffer layer 112 and the second buffer layer 122 are respectively attached to both sides of the laminate 200, thereby achieving clamping and support of the laminate 200 by the first support component 110 and the second support component 120. The first buffer layer 112 and the second buffer layer 122 provide buffering and heat absorption, and the first support plate 111 and the second support plate 121 provide support. Therefore, through the support of the first support component 110 and the second support component 120, the adhesion of the prepreg 210 of the laminate 200 caused by factors such as temperature and pressure can be effectively prevented, while avoiding damage to the prepreg 210 of the laminate 200 during packaging and transportation.

[0030] In a preferred embodiment, the dimensions of the first support component 110 and the second support component 120 are both slightly larger than the dimensions of the laminate 200. Thus, when the first support component 110 and the second support component 120 are clamped between the two sides of the laminate 200, a certain gap 130 will be formed at the end of the laminate 200, such as... Figure 2-3 As shown. Therefore, it can effectively prevent the laminate 200 from being squeezed during handling or transportation, thereby avoiding deformation or damage to the semi-cured sheet 210 of the laminate 200.

[0031] Continue to combine Figure 1-Figure 3As shown, in a preferred embodiment of this utility model, the first support assembly 110 further includes a first isolation sheet 113, which is disposed on the side of the first buffer layer 112 away from the first support plate 111. The first isolation sheet 113 is used to isolate the first buffer layer 112 and the laminate 200. Correspondingly, the second support assembly 120 further includes a second isolation sheet 123, which is disposed on the side of the second buffer layer 122 away from the second support plate 121, and is used to isolate the second buffer layer 122 and the laminate 200. In this embodiment, the first isolation sheet 113 and the second isolation sheet 123 are used for isolation, effectively preventing impurities generated by the first buffer layer 112 and the second buffer layer 122 from being introduced into the semi-cured sheet 210 of the laminate 200 and affecting the quality.

[0032] Understandably, if the first buffer layer 112 and the second buffer layer 122 are made of materials that are not prone to producing impurities, then the first isolation sheet 113 and the second isolation sheet 123 can be omitted to simplify the structure of the prepreg packaging device 100, thereby reducing the overall thickness and weight of the prepreg packaging device 100 after packaging the laminate 200, making it easier to handle and transport, and reducing transportation costs.

[0033] Continue to combine Figure 1-Figure 3 As shown, in this embodiment, both the first support component 110 and the second support component 120 are composed of three independent plates stacked together, and the three plates are not fixed after stacking. When encapsulating the laminate 200, the three plates are simply stacked on one side of the laminate 200 in the set order. However, it is not limited to the aforementioned structural arrangement. For example, in other embodiments, the three plates of the first support component 110 and the second support component 120 can be integrally formed or pre-fixed as one piece, and the first support component 110 and the second support component 120 can be directly used. See the following description for details.

[0034] Continue to combine Figure 1-Figure 3 As shown, in one embodiment of this utility model, both the first support plate 111 and the second support plate 121 are preferably made of materials with high hardness and light weight. For example, the first support plate 111 and the second support plate 121 can be made of plastic, wood, cardboard, etc. In this way, on the one hand, using the first support plate 111 and the second support plate 121 to support the laminate 200 can effectively prevent damage or compression to the semi-cured sheet 210 of the laminate 200 during transportation and handling; on the other hand, reducing the weight of the first support plate 111 and the second support plate 121 can reduce the overall weight of the first support assembly 110, the second support assembly 120, and the laminate 200, making it easier to handle and transport, and reducing transportation costs.

[0035] More preferably, the first support plate 111 and the second support plate 121 have a hollow structure, or the interior of the first support plate 111 and the second support plate 121 has a honeycomb structure. For example, the first support plate 111 and the second support plate 121 are preferably corrugated plates. In this way, while maintaining the rigidity of the first support plate 111 and the second support plate 121, the weight of the first support plate 111 and the second support plate 121 can be further reduced, which facilitates packaging, handling and transportation, and reduces transportation costs.

[0036] Understandably, the first support plate 111 and the second support plate 121 are not limited to the materials mentioned above. Depending on the specific support requirements, other materials with greater hardness can be selected. For example, the first support plate 111 and the second support plate 121 can also be selected from materials with greater hardness, such as metal plates, to achieve better support strength and more effectively prevent damage to the semi-cured sheet 210 of the laminate 200 during transportation and handling.

[0037] Continue to combine Figure 1-Figure 3 As shown, in one embodiment of this utility model, both the first buffer layer 112 and the second buffer layer 122 have a honeycomb structure inside, thus possessing good heat adsorption and pressure buffering capabilities. This prevents internal heat concentration and alleviates external pressure on the first support component 110 and the second support component 120, effectively solving the problem of prepreg adhesion caused by temperature rise or pressure from stacked prepregs 210. Furthermore, increasing the porosity reduces the weight of the first buffer layer 112 and the second buffer layer 122, thereby reducing the overall weight of the first support component 110, the second support component 120, and the laminate 200, facilitating handling and transportation, and reducing transportation costs.

[0038] In a preferred embodiment, the first buffer layer 112 and the second buffer layer 122 are preferably foam layers. Foam is elastic, lightweight, and flexible. Using foam layers as buffer layers can effectively absorb and insulate heat and buffer the external pressure on the prepreg 210, thereby preventing the prepreg 210 from sticking together when the temperature is too high or under pressure.

[0039] Understandably, the first buffer layer 112 and the second buffer layer 122 can also be made of other lightweight, elastic and heat-absorbing materials, such as sponge layer, foam plastic layer, cotton layer, fiber filling layer, recycled paper layer or polyester fiber layer, etc., which can effectively avoid heat concentration and reduce pressure, thereby effectively solving the problem of semi-cured sheet 210 sticking due to temperature rise or pressure caused by stacking semi-cured sheet 210.

[0040] Continue to combine Figure 1-Figure 3As shown, in one embodiment of this utility model, both the first isolation sheet 113 and the second isolation sheet 123 are preferably plastic films. Furthermore, the plastic films can be molded from any material such as polycarbonate (PC), polypropylene (PP), polyethylene terephthalate (PET), and polyvinyl chloride (PVC), and are not specifically limited in this application. Using plastic films to isolate the laminate 200 from the foam layer effectively prevents impurities from the foam layer from being introduced into the prepreg 210 of the laminate 200 and affecting the quality of the prepreg 210, thus achieving the effect of eliminating impurities.

[0041] Recombined Figure 1-Figure 3 As shown, in this invention, the prepreg packaging device 100 further includes a packaging bag 140, which is used to contain the package formed by the first support component 110 and the second support component 120 clamping the laminate 200. More specifically, the packaging bag 140 is also vacuum-sealed. After vacuuming, the packaging bag 140 seals and fixes the first support component 110, the second support component 120, and the laminate 200, making it easier to handle and transport.

[0042] Recombined Figure 1-Figure 3 As shown, the encapsulation process of the prepreg 210 by the prepreg encapsulation device 100 of this utility model will be described.

[0043] First, multiple pre-cut prepreg sheets 210 are stacked to obtain a laminate 200. The number of prepreg sheets 210 in each laminate 200 is not specifically limited. Furthermore, the method of stacking the prepreg sheets 210 is a conventional method in the art.

[0044] Then, the laminate 200 is encapsulated. In one encapsulation method, a first spacer 113 and a second spacer 123 are placed above and below the laminate 200, respectively. Figure 1 In the illustrated embodiment, a first isolation sheet 113 is placed above the laminate 200, and a second isolation sheet 123 is placed below the laminate 200, with the first isolation sheet 113 and the second isolation sheet 123 adhering to both sides of the laminate 200. Next, a first buffer layer 112 is placed above the first isolation sheet 113, and a second buffer layer 122 is placed below the second isolation sheet 123. Finally, a first support plate 111 is placed above the first buffer layer 112, and a second support plate 121 is placed below the second buffer layer 122. Thus, a first support assembly 110 and a second support assembly 120 are formed on the upper and lower sides of the laminate 200, respectively. The first support assembly 110 and the second support assembly 120 clamp and support the laminate 200, and together they constitute a packaging body, as shown below. Figure 2 As shown. Furthermore, the first insulating sheet 113 isolates the first buffer layer 112 from the upper side of the laminate 200, and the second insulating sheet 123 isolates the second buffer layer 122 from the lower side of the laminate 200, as... Figure 2 As shown.

[0045] It should be noted that the arrangement is not limited to the order in which the first support plate 111, the first buffer layer 112, the first isolation sheet 113, the second support plate 121, the second buffer layer 122, and the second isolation sheet 123 are placed. For example, in other embodiments, one of the first support assembly 110 and the second support assembly 120 may be stacked sequentially on one side of the laminate 200, and then the other of the first support assembly 110 and the second support assembly 120 may be stacked sequentially on the other side of the laminate 200. This does not affect the clamping and fixing of the laminate 200 by the first support assembly 110 and the second support assembly 120.

[0046] Furthermore, the positions of the first support component 110 and the second support component 120 are not... Figure 1 As shown, interchange the positions of the two without affecting their clamping and support of the laminate 200.

[0047] Finally, the package body is placed into the packaging bag 140, and the packaging bag 140 is vacuum-sealed to seal and secure the package body. Figure 3 As shown, it is easier to handle and transport.

[0048] Understandably, the encapsulation method is not limited to the above-described method. For example, in another encapsulation method, the first support component 110 and the second support component 120 can be pre-manufactured and used directly when encapsulating the laminate 200. That is, the first support component 110 is obtained by pre-stacking the first support plate 111, the first buffer layer 112, and the first isolation sheet 113 in sequence; then, the second support plate 121, the second buffer layer 122, and the second isolation sheet 123 are stacked in sequence to obtain the second support component 120. The three layers of the first support component 110 and the second support component 120 may or may not be fixed. When encapsulating the laminate 200, the first support component 110 and the second support component 120 are directly used. The laminate 200 is stacked on the second spacer 123 of the second support component 120, and finally the first support component 110 is stacked on top of the laminate 200, so that the first spacer 113 adheres to the laminate 200; or, the laminate 200 is stacked on the first spacer 113 of the first support component 110, and then the second spacer 123 of the second support component 120 is adhered to top of the laminate 200. Similarly, a package consisting of the first support component 110, the laminate 200, and the second support component 120 can be obtained. This encapsulation method is also applicable when the first support component 110 and the second support component 120 are an integral structure.

[0049] In summary, the prepreg packaging device 100 of this invention uses a first support component 110 and a second support component 120 to clamp the laminate 200 obtained by stacking multiple prepregs 210. The first support component 110 has a first support plate 111 and a first buffer layer 112 arranged sequentially, with the first support plate 111 having a higher hardness than the first buffer layer 112, and the first buffer layer 112 having a certain degree of flexibility. The second support component 120 has a second support plate 121 and a second buffer layer 122 arranged sequentially, with the second support plate 121 having a higher hardness than the second buffer layer 122, and the second buffer layer 122 having a certain degree of flexibility. In use, the first buffer layer 112 and the second buffer layer 122 are arranged opposite each other and respectively adhere to the two sides of the laminate 200. Since the first buffer layer 112 and the second buffer layer 122 can absorb heat, avoid heat concentration, and buffer pressure, they can effectively solve the problem of prepreg 210 sticking together due to temperature rise or pressure from stacked prepreg 210. Furthermore, by using the first support plate 111 and the second support plate 121, which have rigidity, to support the entire laminate 200, damage to the prepreg 210 of the laminate 200 can be effectively prevented during transportation and handling.

[0050] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
