Description

Film pressing machine

Technical Field

The present invention relates to a film pressing machine, and more particularly, to a film pressing machine including two working chambers (a film pressing device and a planar pressing device).

Background

With the miniaturization and high performance of electronic devices, Multilayer circuit boards, so-called Multilayer boards (multilayered PCBs), have been widely used as electronic circuit boards mounted on electronic devices. The multilayer board is formed by alternately stacking a plurality of layers, a circuit having a concavo-convex shape is printed on the surface of a part of the layers, and the other part of the layers is a resin film having an insulating property. For example, in order to manufacture a multilayer board having a multi-layer structure, the following steps must be repeated: a step of forming a circuit pattern on a base material, a step of laminating a resin film on the base material, and a step of hardening the resin film.

The cumulative stacking of the layers may be accomplished by means of a laminator. Generally, the laminator can perform a lamination process to press the laminate and the substrate so that the laminate and the substrate are initially bonded to form a semi-finished laminate. Then, a plane pressing process is performed, and the laminator flattens the laminated semi-finished product to make the surface flat.

Currently, film presses may face the problem of poor lamination quality. One of the problems is that air bubbles or air gaps remain between the laminate and the base material during press-fitting, and the other problem is that the pressure distribution between the laminate and the base material during press-fitting is not uniform.

Disclosure of Invention

In view of the above problems, the present invention discloses a film pressing machine, which is helpful to solve the problem of poor lamination quality of the existing film pressing machine.

The film pressing machine disclosed by the invention comprises a film pressing device, a plane pressurizing device and at least one inflatable sealing member. The film pressing device comprises two film pressing pieces, and the film pressing device is arranged to clamp the base material and the laminated material between the two film pressing pieces and press the laminated material to enable the laminated material to be tightly adhered to the surface of the base material. The plane pressing device comprises two flattening pieces, and the plane pressing device is arranged to clamp the laminated material and the base material which are tightly adhered between the two flattening pieces and push the laminated material and the base material. The inflatable sealing member is arranged between the two pressing film pieces or between the two flattening pieces. The inflatable sealing member includes a first inflatable ring and a second inflatable ring. The first and second air-filled rings are arranged to press against each other when the two film pressing members or the two pressing members approach each other, so that the space between the two film pressing members or the space between the two pressing members is kept in an airtight state.

The invention further discloses a film pressing machine which comprises two film pressing pieces, a conveying device and an inflatable sealing member. The conveying device is arranged to convey the object through the space between the two film pressing members. The inflatable sealing member comprises a first inflatable ring and a second inflatable ring which are arranged between the two pressing film pieces. At least a portion of the delivery device is positioned between the first and second inflatable rings. The first and second air-filling rings are arranged to press against each other when the two film pressing members are close to each other, so that the space between the two film pressing members is kept in an airtight state.

The film pressing machine disclosed by the invention further comprises a plane pressurizing device, a conveying device and an inflatable sealing member. The plane pressing device comprises two flattening pieces. The conveying device is arranged to convey the object through the space between the two flattening pieces. The inflatable sealing member is arranged between the two pressing film pieces or between the two flattening pieces. The inflatable sealing member includes a first inflatable ring and a second inflatable ring. The transfer device is at least partially positioned between the first and second inflatable rings. The first and second inflatable rings are arranged to abut against each other when the two flattening members are brought close to each other, so that the space between the two flattening members is kept in an airtight state.

The invention also discloses a film pressing machine which comprises a film pressing device, a plane pressurizing device and a sealing ring. The film pressing device is arranged to tightly bond the base material and the laminated material. The plane pressing device is arranged to press the laminated material and the substrate tightly. The sealing ring is arranged on the film pressing device or the plane pressurizing device. The film pressing device or the plane pressurizing device is provided with a groove and a ventilation flow passage communicated with the groove, and the sealing ring is movably arranged in the groove.

The invention also discloses a film pressing machine which comprises a plane pressurizing device and a sealing ring. The sealing ring is movably arranged in the groove and moves between a sealing state and an initial state. In the sealed state, the sealing ring closes the opening of the groove and protrudes out of the opening. In the initial state, the sealing ring is separated from the edge of the opening.

According to the laminator disclosed by the present invention, the inflatable sealing member comprises a first inflatable ring and a second inflatable ring. When the two film pressing pieces or the two flattening pieces are close to each other, the first inflating ring and the second inflating ring are pressed against each other, so that the space between the two film pressing pieces or the space between the two flattening pieces is kept in an airtight state. Taking the case that the inflatable sealing member is disposed between the two flattening members as an example, since the first inflatable ring and the second inflatable ring can be in an uninflated state before the airtight space is not formed, the two flattening members can have a large stroke without being interfered by the inflatable sealing member when approaching each other, which helps the flattening members to push the laminated semi-finished product with a small thickness. Moreover, the feeding end and the discharging end of the plane pressurizing device can be provided with larger openings to allow the conveying film and the laminated semi-finished product to pass through without interfering with the inflatable sealing component, thereby being beneficial to the miniaturization of the plane pressurizing device. In addition, the first inflation ring and the second inflation ring both have flexibility and can be tightly attached to the conveying film, and the air tightness of the closed space is increased.

The laminator disclosed herein can also be configured with a sealing ring disposed in the groove, and the groove can be filled with a gas to push the sealing ring to protrude out of the groove. A part of the sealing ring protruding out of the groove can keep the airtight state of the airtight space between the two film pressing pieces of the film pressing device and/or between the two flattening pieces of the plane pressing device. At the moment, the negative pressure air exhaust can be used for reducing the pressure of the closed space, so that the qualification rate of the film pressing machine and the film pressing quality are improved.

The foregoing description of the present disclosure and the following detailed description are presented to illustrate and explain the principles and spirit of the present invention and to provide further explanation of the invention as claimed.

Detailed Description

The detailed features and advantages of the present invention are described in detail in the following embodiments, which are sufficient for a person skilled in the art to understand the technical content of the present invention and to implement the present invention, and the related objects and advantages of the present invention can be easily understood by those skilled in the art from the disclosure of the present specification, claims and drawings. The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.

Referring to fig. 1 to fig. 3, wherein fig. 1 is a schematic view of a laminator according to an embodiment of the invention. Fig. 2 is a schematic view of a film pressing device in the film pressing machine of fig. 1. Fig. 3 is a schematic view of a planar pressing device in the laminator of fig. 1. In the present embodiment, the laminator 1 includes a laminator device 10, a planar pressing device 20, a conveying device 30, and an inflatable sealing member 40.

The film pressing device 10 includes two film pressing members 110 disposed opposite to each other, and each film pressing member 110 includes a main body 111 and a pressing unit 112 connected to each other. The main body 111 may be vertically lifted by a driving device (not shown) to close the main bodies 111 of the two film pressing members 110. After the main bodies 111 of the two film pressing members 110 are closed, a closed space can be formed to accommodate the laminated material and the substrate. The pressing units 112 of the two pressing members 110 can be moved close to each other by the vertical lifting body 111 to press the laminated material and the substrate. In the embodiment, the pressurizing unit 112 is further provided with a heater (not shown) to heat the laminated material or the substrate during the lamination process, but the invention is not limited thereto.

The plane pressing device 20 is located at one side of the film pressing device 10, and includes two pressing members 210 disposed opposite to each other, and each pressing member 210 includes a main body 211 and a pressing unit 212 connected to each other. The main body 211 can be vertically lifted by the driving device to bring the pressing units 212 of the two pressing members 210 close to each other to press the laminated material on the surface of the substrate. The pressing unit 212 is further provided with a heater (not shown) to heat the laminated material or the substrate during the planar pressing process, but the invention is not limited thereto.

In the present embodiment, the planar pressing device 20 further includes a plurality of driving mechanisms 220 and Load cells (Load cells) 230. The driving mechanism 220 is connected to the main body 211 of one of the pressing members 210, and the load cell 230 is disposed on at least one of the driving mechanisms 220. One of the flattening members 210 can be vertically raised and lowered toward and away from the other flattening member 210 by a drive mechanism 220. Each drive mechanism 220 includes a servo motor 221 and a screw 222 connected thereto. One end of the screw 222 is connected to the main body 211 of the pressing member 210 provided with this driving mechanism 220, and the axis of the screw 222 is offset from the center of the main body 211 of the pressing member 210. More specifically, the driving mechanisms 220 are respectively disposed at or near a plurality of corners of the substantially rectangular flattening member 210. The screw 222 of one of the driving mechanisms 220 has a flange 2121, and the load cell 230 is clamped between the flange 2121 and a bottom 2111 of the main body 211 of the corresponding flattening member 210 to which the screw 222 is connected.

The conveying device 30 is configured to convey the object (substrate and/or laminated material) sequentially through the film pressing device 10 and the plane pressing device 20. In detail, the conveying device 30 includes two conveying films 310, such as but not limited to polyethylene terephthalate (PET) film, and the conveying films 310 form a continuous belt-like film. A plurality of rollers (not shown) of the conveying device 30 may be used for winding the conveying film 310, and the object (substrate and/or laminated material) may be clamped between the two conveying films 310, so as to move the object relative to the film pressing device 10 and the plane pressing device 20 by synchronously winding the two conveying films 310.

The inflatable sealing member 40 is disposed on the planar pressing device 20, and can be used to maintain the space between the two pressing members 210 in an airtight state. In detail, the pneumatic sealing member 40 includes a first pneumatic ring 410 and a second pneumatic ring 420. A first inflatable ring 410 is provided to the body 211 of one of the flattening members 210 and a second inflatable ring 420 is provided to the body 211 of the other flattening member 210. The delivery device 30 has at least a portion positioned between the first inflation ring 410 and the second inflation ring 420; in detail, each of the transfer films 310 has a portion located between the first and second inflation rings 410 and 420. In addition, the first and second inflation rings 410 and 420 can be engaged with the concave groove formed on the main body 211 of the flattening element 210. The degree of sealing between the first and second inflation rings 410 and 420 can be adjusted by inflating gas into the first and second inflation rings 410 and 420 and by evacuating gas from the first and second inflation rings 410 and 420, thereby adjusting the degree of vacuum in the space between the two pressing members 210.

In the embodiment, the first inflation ring 410 and the second inflation ring 420 are a single component, but the invention is not limited thereto. In some other embodiments, multiple inflation strips may be disposed on the body of the platen, and the inflation strips are connected to form an inflation ring.

The laminator disclosed by the invention can execute the following procedures: conveying the laminated material and the base material to a film pressing device through a conveying device; pressing the laminated material and the base material by a film pressing device to form a laminated semi-finished product (film pressing process); conveying the laminated semi-finished product from the film pressing device to a plane pressurizing device through a conveying device; and flattening the laminated semi-finished product by a plane pressing device (plane pressing process) to flatten the laminated material of the laminated semi-finished product.

Fig. 4 is a schematic view of the lamination device of fig. 2 for bonding the laminated material to the base material. The conveying film 310 of the conveying device 30 conveys the laminated material P1 (e.g., an insulating resin film) and the base material P2 (e.g., a substrate having a circuit or a semiconductor package on the surface) between the two film pressing members 110 of the film pressing device 10. The lower film pressing member 110 is raised close to the upper film pressing member 110, so that the pressing units 112 of the two film pressing members 110 sandwich the transfer film 310, the laminated material P1 and the base material P2. In this embodiment, the pressurizing unit 112 may be an air bag that is inflated to further press the laminated material P1 to be closely adhered to the surface of the substrate P2. Here, the function of the transport film 310 is to transport the laminated material P1 and the base material P2, and to prevent the laminated material P1 from being heated and melted and adhering to the laminator 10 when a heater is disposed in the pressing unit 112 of the laminator 110.

When the lower film pressing member 110 rises to approach the upper film pressing member 110, the main bodies 111 of the two film pressing members 110 can be closed to form a closed space S1 for accommodating the laminated material P1, the substrate P2 and the conveying film 310. Furthermore, the pressure in the enclosed space S1 can be reduced by negative pressure pumping to eliminate air bubbles inside the laminated material P1 and/or air gaps between the laminated material P1 and the base material P2, thereby improving the yield and the sealing quality of the film lamination process.

The laminated material P1 and the base material P2 are bonded to each other to form a laminated semi-finished product P12. Since the surface of the substrate P2 may have circuit patterns, through holes, or semiconductor devices, the laminate P1 is not flat enough due to the effects of the bumps, and thus needs to be further flattened. Referring to fig. 5 and 6, the plane pressing apparatus of fig. 3 is a schematic view of flattening the laminated material adhered to the base material. The transfer film 310 of the transfer device 30 transfers the laminated semi-finished product P12 to between the two pressing members 210 of the plane pressing device 20. The servo motor 221 of the driving mechanism 220 rotates to lift the main body 211 of the lower press member 210 close to the main body 211 of the upper press member 210, so that the press units 212 of the two press members 210 sandwich the transfer film 310 and the laminated semi-finished product P12. In the present embodiment, the flattening unit 212 may include a flexible metal plate capable of pressing the laminated semi-finished product P12 so as to flatten the laminated material P1 attached to the base material P2. Therefore, the two flattening units 212 press the laminated semi-finished product P12, so that the thickness of the laminated finished product is uniform, and the laminated finished product has a flat mirror surface (the surface of the laminated material P1). Here, the function of the conveying film 310 is to prevent the laminated material P1 from being heated and melted and adhering to the plane pressing device 20 when the heater is disposed in the flattening unit 212 of the flattening tool 210 in addition to the function of conveying the laminated semi-finished product P12.

As shown in fig. 6, when the lower pressing member 210 is lifted close to the upper pressing member 210, a closed space S2 is formed between the two pressing members 210 to accommodate the laminated semi-finished product P12 and the conveying film 310. In detail, the first and second inflation rings 410 and 420 of the inflatable sealing member 40 may be in an initial state of being uninflated in a normal state. When the main bodies 211 of the two pressing members 210 approach each other, the first inflation ring 410 and the second inflation ring 420 are respectively attached to the upper and lower conveying films 310, and the first inflation ring 410 and the second inflation ring 420 are inflated and expanded to be pressed against each other, so that the sealed space S2 between the two pressing members 210 is kept in an airtight state, at this time, the sealed space S2 can be decompressed by negative pressure air suction, so as to eliminate air bubbles inside the laminated semi-finished product P12 and/or air gaps between the pressing units 212 and the laminated semi-finished product P12, thereby improving the qualification rate of the plane pressing process and the pressing quality. The first inflation ring 410 and the second inflation ring 420 may be inflated simultaneously during the approach of the applanation members 210 or inflated after the approach of the applanation members 210.

Compared with the conventional partial film laminating machine which uses a rigid follower including a spring or a leaf spring as the sealing member, the first and second inflation rings 410 and 420 can be in the non-inflated state before the airtight space S2 is formed, so that the two flattening members 210 can have a larger stroke without being interfered by the inflation sealing member 40 when approaching each other, which helps the flattening members 210 to push the laminated semi-finished product P12 with a thinner thickness. Further, the feed end and the discharge end of the plane pressing device 20 may have large openings to allow the transfer film 310 and the laminated semi-finished product P12 to pass therethrough without interfering with the inflatable sealing member 40, thereby contributing to miniaturization of the plane pressing device 20.

In addition, in the case of a partial film laminator of the related art in which a single inflation ring (or sealing ring) is used as a sealing member, when a transport film is disposed, one side of the transport film close to the inflation ring can be tightly attached to the inflation ring, but the other side is difficult to tightly attach to the rigid body of the platen, which results in poor airtightness of the sealed space. In the present embodiment, the first and second inflation rings 410 and 420 are both flexible and can be tightly attached to the transport film 310, which contributes to increasing the airtightness of the sealed space S2.

In this embodiment, the driving mechanism 220 may drive the pressing members 210 to press one of the pressing members 210 by stopping the servo motor 221 after moving the one pressing member 210 by a predetermined distance, which may be included in a command input to the servo motor 221 by the controller, so as to press the bonded laminate P1 and the base material P2 (the laminated semi-finished product P12). Alternatively, the servo motor 221 may drive the lower pressing member 210 to perform pressing or stop pressing according to the pressure signal sensed by the load cell 230. Further, when the load cell 230 senses that the pressure value is greater than or less than the predetermined threshold value, the load cell 230 outputs a pressure signal to the servo motor 221, thereby controlling the operation of the driving mechanism 220.

In the first embodiment, the inflatable sealing member 40 is only disposed on the planar pressurizing device 20, but the invention is not limited thereto. In some embodiments, another inflatable sealing member may be additionally disposed on the film pressing device, or only the film pressing device may be disposed on the inflatable sealing member. Fig. 7 is a schematic view of a laminator according to another embodiment of the invention. In the present embodiment, the laminator 1a includes a laminator device 10, a planar pressing device 20, a conveyor device 30, a inflatable sealing member 40, and an inflatable sealing member 50. The details of the film pressing device 10, the plane pressing device 20, the conveying device 30, and the inflatable sealing member 40 can be described with reference to fig. 1 to 3 and their related paragraphs, and will not be described again below.

The inflatable sealing member 50 is disposed on the film pressing device 10, and is used to maintain the space between the two film pressing members 110 in an airtight state. In detail, the pneumatic sealing member 50 includes a first pneumatic ring 510 and a second pneumatic ring 520. The first inflation ring 510 is provided to one of the pressing members 110, and the second inflation ring 520 is provided to the other pressing member 110. The delivery device 30 has at least a portion positioned between the first inflatable ring 510 and the second inflatable ring 520. When the lower film pressing member 110 rises to approach the upper film pressing member 110, the main bodies 111 of the two film pressing members 110 can be closed to form a closed space S1 for accommodating the laminated material P1, the substrate P2 and the conveying film 310. In detail, the first and second inflation rings 510 and 520 may be in an uninflated initial state before the two diaphragm pressing members 110 approach. When the two pressure film members 110 approach each other, the first and second inflation rings 510 and 520 inflate and press against each other, so that the sealed space S1 between the two pressure film members 110 is kept airtight.

Fig. 8 is a schematic view of a laminator according to yet another embodiment of the invention. Fig. 9 is a partially enlarged schematic view of the laminator of fig. 8. The laminator includes a planar pressing device 20, a conveying device 30, and a sealing ring 40b. For convenience of illustration and easy understanding of the differences between the present embodiment and other embodiments, fig. 8 omits to illustrate some objects (such as the film pressing device, the driving mechanism, etc.) of the film pressing machine.

The plane pressing device 20 includes two flattening members 210 arranged in an opposing manner, and each flattening member 210 includes a main body 211 and a flattening unit 212 connected to each other. The main body 211 can be vertically lifted by the driving device to bring the pressing units 212 of the two pressing members 210 close to each other to press the laminated material on the surface of the substrate.

The transport device 30 is configured to transport articles (substrates and/or laminates) through the planar pressing device 20. The transport device 30 includes two transport films 310, such as, but not limited to, polyethylene terephthalate (PET) film, and the transport films 310 form a continuous belt-like film. A plurality of rollers (not shown) of the conveying device 30 may be used for winding the conveying film 310, and the object (substrate and/or laminated material) may be clamped between the two conveying films 310, so as to move relative to the plane pressing device 20 by synchronously winding the two conveying films 310.

The sealing ring 40b is, for example and without limitation, an O-ring, and is disposed on the main body 211 of one of the pressing flat members 210 of the planar pressing device 20. In detail, the main body 211 has an annular groove 211b and a ventilation channel 211c communicating with the groove 211b, and the sealing ring 40b is movably disposed in the groove 211b. The vent channel 211c may be connected to a gas supply source (not shown) to introduce a gas (e.g., air, nitrogen or helium) into the groove 211b through the vent channel 211c, so as to move the sealing ring 40b between a sealing state (as shown in fig. 9) and an initial state (as shown in fig. 8).

In the present embodiment, the annular groove 211b is close to the edge of the flattening unit 212 of the planar pressing device 20, and the groove 211b has an opening 2122. The opening 2122 is located on the outer surface of the main body 211, and the width W1 of the opening 2122 is less than the maximum width W2 of the sealing ring 40b. The groove 211b further has a bottom wall surface 2123 opposite to the opening 2122, and the width W1 of the opening 2122 is smaller than the width W3 of the bottom wall surface 2123.

As shown in fig. 8 and 9, in the case where the planar pressurizing means 20 is not operated, the seal ring 40b is normally in the initial state. In the initial state, the seal ring 40b is separated from the edge of the opening 2122.

Referring next to fig. 10 and 11 together, wherein fig. 10 is a schematic view of the laminator of fig. 8 with the sealing ring in a sealed state, and fig. 11 is a partially enlarged schematic view of the laminator of fig. 10. The transfer device 30 transfers the laminated semi-finished product P12 between the two pressing members 210 of the plane pressing device 20. The main body 211 of the lower press member 210 is driven to rise close to the main body 211 of the upper press member 210, so that the press units 212 of the two press members 210 sandwich the transfer film 310 and the laminated semi-finished product P12. While or after the flattening unit 212 sandwiches the transport film 310 and the laminated semi-finished product P12, gas is introduced from the gas flow passage 211c into the groove 211b, and the seal ring 40b is brought from the initial state to the sealed state. Further, the sealing ring 40b may be made of a rigid material or a material with a low elastic strain, which can be pushed by the gas to move upward to close the opening 2122 of the groove 211b when the gas is filled into the groove 211b. A portion of sealing ring 40b protrudes through opening 2122 to adhere to delivery device 30 and press against body 211 of the other flattening piece 210. Therefore, the enclosed space S2 between the two pressing members 210 can be kept in an airtight state, and the enclosed space S2 can be depressurized by negative pressure pumping so as to eliminate air bubbles inside the laminated semi-finished product P12 and/or air gaps between the pressing units 212 and the laminated semi-finished product P12, thereby improving the yield of the plane pressing process and the pressing quality.

Fig. 8 to 11 illustrate an example in which the sealing ring 40b is disposed in the groove 211b formed in the planar pressurizing device 20, but the present invention is not limited thereto. In other embodiments, the sealing ring may be disposed on the film pressing member of the film pressing device instead of or in addition to the planar pressurizing device.

In summary, the laminator according to the present disclosure is configured with an inflatable sealing member, wherein the inflatable sealing member includes a first inflatable ring and a second inflatable ring. When the two film pressing pieces or the two flattening pieces are close to each other, the first inflating ring and the second inflating ring are attached to each other, so that the space between the two film pressing pieces or the space between the two flattening pieces is kept in an airtight state. Taking the case that the inflatable sealing member is disposed between the two flattening members as an example, since the first inflatable ring and the second inflatable ring can be in an uninflated state before the airtight space is not formed, the two flattening members can have a large stroke without being interfered by the inflatable sealing member when approaching each other, which helps the flattening members to push the laminated semi-finished product with a small thickness. Moreover, the feeding end and the discharging end of the plane pressurizing device can be provided with larger openings to allow the conveying film and the laminated semi-finished product to pass through without interfering with the inflatable sealing component, thereby being beneficial to the miniaturization of the plane pressurizing device. In addition, the first inflation ring and the second inflation ring are flexible and can be tightly attached to the conveying film, and the air tightness of the closed space is improved.

Moreover, the film pressing machine disclosed by the invention can be also provided with a sealing ring which is arranged in the groove, and the groove can be filled with gas to push the sealing ring to protrude out of the groove. A part of the sealing ring protruding out of the groove can keep the airtight state of the airtight space between the two film pressing pieces of the film pressing device and/or between the two flattening pieces of the plane pressing device. At the moment, the negative pressure air exhaust can be used for reducing the pressure of the closed space, so that the qualification rate of the film pressing machine and the film pressing quality are improved.
