Description

Laminator

The present invention relates to a laminating machine, in particular to a laminating machine including two working chambers (a laminating device and a plane pressurizing device).

With the miniaturization and high performance of electronic equipment, electronic circuit substrates mounted on electronic equipment widely use multilayer circuit substrates, which are so-called multilayer PCBs. The multi-layer board is formed by stacking multiple layers alternately. The surface of some layers is printed with circuits with concave and convex shapes, and some other layers are insulating resin films. For example, in order to manufacture a multilayer board with a multi-layer structure, the steps of forming a circuit pattern on a base material, laminating a resin film on the base material, and hardening the resin film must be repeated.

The cumulative superposition of multiple layers can be done by a lamination machine. Generally speaking, the laminating machine can carry out the laminating process, pressurizing the laminated material and the base material, so that the laminated material and the base material are initially attached to become a laminated semi-finished product. Then carry out the planar pressurization procedure, and the laminating machine will carry out the planarization operation of the laminated semi-finished product, so that the surface becomes flat.

At present, lamination machines may face the problem of poor lamination quality. One of the problems is that bubbles or air gaps remain between the laminate and the base material during pressure bonding, and the other problem is uneven pressure distribution between the laminate and the base material during pressure bonding.

In view of the above problems, the present invention discloses a lamination machine, which helps to solve the problem of poor lamination quality of existing lamination machines.

The film laminating machine disclosed in the present invention comprises a film laminating device, a plane pressurizing device and at least one inflatable sealing member. The film lamination device includes two film lamination parts. The film lamination device is configured to clamp a base material and a laminated material between the two film lamination parts and press them, so that the laminated material is tightly bonded to the surface of the base material. The planar pressing device includes two flattening parts, and the planar pressing device is configured to clamp and push the closely bonded laminated material and base material between the two flattening parts. The inflatable sealing member is arranged between the two film pressing parts or between the two flattening parts. The inflatable sealing member includes a first inflatable ring and a second inflatable ring. The first inflatable ring and the second inflatable ring are arranged to press against each other when the two film-pressing parts or the two flattening parts are close to each other, so that the space between the two film-pressing parts or the two flattening parts is kept in an airtight state .

Another disclosed film laminating machine of the present invention includes two film laminating parts, a conveying device and an inflatable sealing member. The conveying device is configured to convey objects through the space between the two pressing film parts. The inflatable sealing member includes a first inflatable ring and a second inflatable ring arranged between the two pressure film parts. At least a portion of the delivery device is located between the first inflatable ring and the second inflatable ring. The first inflatable ring and the second inflatable ring are arranged to press against each other when the two film-pressing parts are close to each other, so that the space between the two film-pressing parts is kept in an airtight state.

The laminating machine further disclosed by the present invention comprises a plane pressurizing device, a conveying device and an inflatable sealing member. The planar pressing device includes two flattening parts. The conveying device is configured to convey objects through the space between the two flattening members. The inflatable sealing member is arranged between the two film pressing parts or between the two flattening parts. The inflatable sealing member includes a first inflatable ring and a second inflatable ring. At least a portion of the delivery device is located between the first inflatable ring and the second inflatable ring. The first inflatable ring and the second inflatable ring are configured to press against each other when the two flattening parts are close to each other, so that the space between the two flattening parts is kept in an airtight state.

The laminating machine further disclosed by the present invention includes a laminating device, a flat pressing device and a sealing ring. The laminating device is set to bond the base material and the laminated material. The planar pressing device is set to push and press the laminated material and the base material which are closely bonded. The sealing ring is arranged on the laminating device or the flat pressing device. The laminating device or the planar pressing device has a groove and a flow channel connected with the groove, and the sealing ring can be movably arranged in the groove.

The laminating machine disclosed in the present invention further comprises a plane pressurizing device and a sealing ring. The sealing ring can be movably arranged in the groove, and the sealing ring moves between a sealing state and an initial state. In the sealed state, the sealing ring closes the opening of the groove and protrudes beyond the opening. In the initial state, the sealing ring is separated from the edge of the opening.

According to the film laminator disclosed in the present invention, the inflatable sealing member includes a first inflatable ring and a second inflatable ring. When the two film-pressing parts or the two flattening parts are close to each other, the first inflatable ring and the second inflatable ring press against each other, so that the space between the two film-pressing parts or the two flattening parts remains airtight. Taking the inflatable sealing member disposed between the two applanation parts as an example to further illustrate, since the first inflatable ring and the second inflatable ring can be in an uninflated state before forming an airtight space, the two applanation parts can not be inflated when they are close to each other. The inflatable sealing member has a larger stroke due to interference, which helps the flattener to push the laminated semi-finished product with a thinner thickness. Moreover, the feed end and discharge end of the planar pressurizing device can have larger openings to allow the transport film and laminated semi-finished products to pass through without interfering with the inflatable sealing member, thereby contributing to the miniaturization of the planar pressurizing device. In addition, both the first inflatable ring and the second inflatable ring are flexible and can closely adhere to the conveying membrane, which helps to increase the airtightness of the enclosed space.

The film laminator disclosed in the present invention can also be equipped 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 from the groove. A part of the sealing ring protruding from the groove can keep the airtight space between the two pressing parts of the film pressing device and/or between the two flattening parts of the planar pressing device in an airtight state. At this time, the confined space can be decompressed by negative pressure suction, thereby improving the yield rate of the laminator and the quality of the lamination.

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 the bottom surface 2111 of the main body 211 of the corresponding flattener 210 connected to the screw 222 .

The conveying device 30 is configured to convey objects (substrates and/or laminates) through the laminating device 10 and the planar pressing device 20 in sequence. In detail, the conveying device 30 includes two conveying films 310 , such as but not limited to polyethylene terephthalate (PET) films, and the conveying films 310 form a continuous strip-shaped film. A plurality of rollers (not shown) of the conveying device 30 can be used to take up the conveying film 310, and the object (substrate and/or laminate) can be clamped between the two conveying films 310, so that by synchronously winding the two The film 310 is transported to connect the object to move relative to the laminating device 10 and the planar pressing device 20 .

The inflatable sealing member 40 is disposed on the plane pressurizing device 20 , which can keep the space between the two flattening parts 210 in an airtight state. In detail, the inflatable sealing member 40 includes a first inflatable ring 410 and a second inflatable ring 420 . The first inflatable ring 410 is disposed on the main body 211 of one of the applanation elements 210 , and the second inflatable ring 420 is disposed on the main body 211 of the other applanation element 210 . At least a part of the conveying device 30 is located between the first inflatable ring 410 and the second inflatable ring 420 ; In addition, the first inflatable ring 410 and the second inflatable ring 420 can be engaged in the grooves formed in the main body 211 of the corresponding flattener 210 . The gap between the first inflatable ring 410 and the second inflatable ring 420 can be adjusted by filling gas into the first inflatable ring 410 and the second inflatable ring 420 and pumping out the gas in the first inflatable ring 410 and the second inflatable ring 420 The tightness between the two flattening parts 210 is used to adjust the vacuum degree of the space between the two flattening parts 210 .

In this embodiment, both the first inflatable ring 410 and the second inflatable ring 420 are a single component, but the invention is not limited thereto. In some other embodiments, a plurality of inflatable strips may be disposed on the main body of the flattener, and these inflatable strips are connected together to form an inflatable ring.

The laminating machine disclosed in the present invention can perform the following procedures: transport the laminated material and base material to the lamination device through the conveying device; The conveying device transports the laminated semi-finished product from the laminating device to the flat pressing device; and through the flat pressing device, the aforementioned laminated semi-finished product is flattened (planar pressing process), so that the laminated material of the laminated semi-finished product is flattened.

Referring to FIG. 4 , it is a schematic diagram of the lamination device of FIG. 2 bonding the laminated material to the base material. The conveying film 310 of the conveying device 30 conveys the laminated material P1 (such as an insulating resin film) and the substrate P2 (such as a substrate with circuits or semiconductor elements on its surface) between the two laminating members 110 of the laminating device 10 . The lower film pressing unit 110 rises close to the upper pressing film unit 110 , so that the pressurizing unit 112 of the two pressing film units 110 clamps the conveying film 310 , the laminated material P1 and the base material P2 . In this embodiment, the pressurizing unit 112 may be an air bag, which can be inflated to further press, so that the laminated material P1 is tightly bonded to the surface of the base material P2. Here, the function of the conveying film 310 is not only to transport the laminated material P1 and the base material P2, but also to prevent the laminated material P1 from being heated and melted when the pressure unit 112 of the lamination member 110 is equipped with a heater. Then adhere to the lamination device 10.

When the lower lamination unit 110 rises close to the upper lamination unit 110 , the main bodies 111 of the two lamination units 110 can be closed to form a closed space S1 for accommodating the laminate P1 , the base material P2 and the conveying film 310 . Furthermore, at this time, negative pressure pumping can be used to decompress the enclosed space S1, so as to eliminate air bubbles inside the laminate P1 and/or the air gap between the laminate P1 and the substrate P2, thereby improving the lamination process. Yield and adhesion quality.

The bonded laminated material P1 and base material P2 become a laminated semi-finished product P12. Since circuit patterns, perforations, or semiconductor elements may be formed on the surface of the substrate P2, the laminate P1 will not be flat enough due to the influence of these unevennesses, and thus needs to be further flattened later. Referring to FIG. 5 and FIG. 6 , it is a schematic diagram of the planar pressing device in FIG. 3 flattening the laminated material closely bonded to the base material. The conveying film 310 of the conveying device 30 conveys the laminated semi-finished product P12 between the two flattening members 210 of the planar pressing device 20 . The servo motor 221 of the driving mechanism 220 rotates, so that the main body 211 of the lower flattening part 210 rises close to the main body 211 of the upper flattening part 210, so that the flattening unit 212 of the two flattening parts 210 clamps the conveying film 310 and the laminated semi-finished product P12 . In this embodiment, the flattening unit 212 may include a flexible metal plate, which can push the laminated semi-finished product P12 to flatten the laminated material P1 attached to the base material P2. Therefore, by pushing the laminated semi-finished product P12 with the two flattening units 212, the thickness of the laminated finished product can be uniformed, 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 not only to transport the laminated semi-finished product P12, but also to prevent the laminated material P1 from adhering to the flat surface after being heated and melted when the flattening unit 212 of the flattening member 210 is equipped with a heater. Pressurization device 20.

In addition, as shown in FIG. 6 , when the lower flattening part 210 rises close to the upper flattening part 210 , a closed space S2 can be formed between the two flattening parts 210 to accommodate the laminated semi-finished product P12 and the conveying film 310 . In detail, the first inflatable ring 410 and the second inflatable ring 420 of the inflatable sealing member 40 can be in an uninflated initial state under normal conditions. When the main bodies 211 of the two flattening parts 210 are close to each other, the first inflatable ring 410 and the second inflatable ring 420 are attached to the upper and lower conveying membranes 310 respectively, and the first inflatable ring 410 and the second inflatable ring 420 are inflated to mutually Pressure, so that the closed space S2 between the two flattened parts 210 maintains an airtight state. At this time, the closed space S2 can be decompressed by negative pressure pumping to eliminate the air bubbles and/or flattened units inside the laminated semi-finished product P12 The air gap between 212 and the laminated semi-finished product P12 improves the yield rate and flattening quality of the planar pressing process. The first inflatable ring 410 and the second inflatable ring 420 can be inflated and expanded at the same time when the two flattened parts 210 are approaching, or inflated and expanded after the two flattened parts 210 are approached.

Compared with some existing film laminators that use rigid followers including springs or shrapnel as sealing members, the first inflatable ring 410 and the second inflatable ring 420 in this embodiment can be in an uninflated state before the closed space S2 is formed. Therefore, when the two flattening parts 210 are close to each other, they can have a larger stroke without being interfered by the inflatable sealing member 40, which helps the flattening part 210 to push the thinner laminated semi-finished product P12. Moreover, the feed end and the discharge end of the planar pressurizing device 20 can have larger openings to allow the conveying film 310 and the laminated semi-finished product P12 to pass without interfering with the inflatable sealing member 40, thereby contributing to the miniaturization of the planar pressurizing device 20 change.

In addition, for some existing laminators that use a single inflatable ring (or sealing ring) as a sealing member, in the case of a conveying film, although the side of the conveying film close to the inflating ring can be closely attached to the inflating ring, the The opposite side is difficult to fit closely with the rigid body of the applanation piece, which results in poor airtightness of the enclosed space. In this embodiment, since both the first inflatable ring 410 and the second inflatable ring 420 are flexible and can closely adhere to the conveying membrane 310 , it is helpful to increase the airtightness of the closed space S2 .

In this embodiment, the driving mechanism 220 may drive the flattening member 210 to push and press the servo motor 221 to move one of the flattening members 210 for a predetermined distance and then stop, so as to press the laminated material P1 and the substrate P2 ( The laminated semi-finished product (P12) is pushed, wherein the predetermined distance may be included in the command input to the servo motor 221 by the controller. Alternatively, the servo motor 221 may drive the lower flattening member 210 to push or stop pushing 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 a preset threshold value, the load cell 230 will output 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 plane pressurizing device 20 , but the present invention is not limited thereto. In some embodiments, another inflatable sealing member may be additionally provided in the lamination device, or only the lamination device has the inflatable sealing member. FIG. 7 is a schematic diagram of a laminator according to another embodiment of the present invention. In this embodiment, the film lamination machine 1 a includes a film lamination device 10 , a planar pressurizing device 20 , a conveying device 30 , an inflatable sealing member 40 and an inflatable sealing member 50 . For the detailed structures of the film laminating device 10, the planar pressurizing device 20, the conveying device 30 and the inflatable sealing member 40, reference may be made to the contents recorded in FIGS.

The inflatable sealing member 50 is disposed on the film lamination device 10 , which can keep the space between the two film lamination parts 110 in an airtight state. In detail, the inflatable sealing member 50 includes a first inflatable ring 510 and a second inflatable ring 520 . The first inflatable ring 510 is disposed on one of the die-film parts 110 , and the second inflatable ring 520 is disposed on the other die-film part 110 . At least a portion of the delivery device 30 is located between the first inflatable ring 510 and the second inflatable ring 520 . When the lower lamination unit 110 rises close to the upper lamination unit 110 , the main bodies 111 of the two lamination units 110 can be closed to form a closed space S1 for accommodating the laminate P1 , the base material P2 and the conveying film 310 . In detail, the first inflatable ring 510 and the second inflatable ring 520 may be in an uninflated initial state before the two pressure film parts 110 approach. When the two pressure film parts 110 are close to each other, the first inflatable ring 510 and the second inflatable ring 520 are inflated and pressed against each other, so that the airtight space S1 between the two pressure film parts 110 remains airtight.

Fig. 8 is a schematic diagram of a film laminating machine according to yet another embodiment of the present invention. FIG. 9 is a partially enlarged schematic view of the laminator shown in FIG. 8 . The laminating machine includes a flat pressing device 20, a conveying device 30 and a sealing ring 40b. For convenience of description and easy understanding of the differences between this embodiment and other embodiments, FIG. 8 omits to show some items of the laminator (such as lamination device, driving mechanism, etc.).

The planar pressing device 20 includes two flattening parts 210 arranged opposite to each other, and each flattening part 210 includes a main body 211 and a flattening unit 212 connected to each other. The main body 211 can be lifted vertically through the driving device, so that the flattening units 212 of the two flattening parts 210 are close to each other, so as to flatten the laminated material on the surface of the substrate.

A conveying device 30 is provided to convey objects (substrates and/or laminates) through the planar pressing device 20 . The conveying device 30 includes two conveying films 310 , which are, for example but not limited to, polyethylene terephthalate (PET) films, and the conveying films 310 form a continuous strip-shaped film. A plurality of rollers (not shown) of the conveying device 30 can be used to take up the conveying film 310, and the object (substrate and/or laminate) can be clamped between the two conveying films 310, so that by synchronously winding the two The film 310 is conveyed to move the object relative to the planar pressing device 20 .

The sealing ring 40b is, for example but not limited to, an O-ring, which is disposed on the main body 211 of one of the flattening parts 210 of the planar pressing device 20 . In detail, the main body 211 has an annular groove 211b and a flow channel 211c communicating with the groove 211b, and the sealing ring 40b is movably disposed in the groove 211b. The ventilation flow channel 211c can be connected to a gas supply source (not shown separately), so that a gas (for example: air, nitrogen or helium) can be introduced into the groove 211b through the ventilation flow channel 211c, so that the sealing ring 40b is in a The movement between the sealed state (as shown in FIG. 9 ) and an initial state (as shown in FIG. 8 ).

In this 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 smaller than the maximum width W2 of the sealing ring 40b. The trench 211b further has a bottom wall 2123 opposite to the opening 2122 , and the width W1 of the opening 2122 is smaller than the width W3 of the bottom wall 2123 .

As shown in Figures 8 and 9, when the planar pressurizing device 20 is not working, the sealing ring 40b is normally in the initial state. In an initial state, the sealing ring 40b is separated from the edge of the opening 2122 .

10 and FIG. 11 together, wherein FIG. 10 is a schematic diagram of the sealing ring of the laminator of FIG. 8 in a sealed state, and FIG. 11 is a partially enlarged schematic diagram of the laminator of FIG. 10 . The conveying device 30 transports the laminated semi-finished product P12 between the two flattening parts 210 of the planar pressing device 20 . Drive the main body 211 of the lower flattening part 210 to rise close to the main body 211 of the upper flattening part 210, so that the flattening units 212 of the two flattening parts 210 clamp the conveying film 310 and the laminated semi-finished product P12. At the same time or after the flattening unit 212 clamps the conveying film 310 and the laminated semi-finished product P12 , gas is introduced from the ventilation channel 211c into the groove 211b, so that the sealing ring 40b is in a sealed state from the initial state. Further, the sealing ring 40b can be made of a rigid material or a material with a low elastic strain. When the gas is filled into the groove 211b, it can be pushed by the gas to move upward to close the opening 2122 of the groove 211b. Part of the sealing ring 40 b protrudes from the opening 2122 to be attached to the delivery device 30 and press against the main body 211 of the other flattening member 210 . In this way, the airtight space S2 between the two flattening parts 210 can be kept in an airtight state. At this time, the air pressure in the airtight space S2 can be decompressed by negative pressure pumping, so as to eliminate air bubbles and/or flatten the laminated semi-finished product P12. The air gap between the unit 212 and the laminated semi-finished product P12 improves the yield rate and flattening quality of the planar pressing process.

8 to 11 illustrate that the sealing ring 40b is disposed in the groove 211b formed in the planar pressurizing device 20 as an example, but the invention is not limited thereto. In other embodiments, the sealing ring can be changed to the laminating part of the laminating device, or the sealing ring can be additionally provided on the laminating device in addition to the planar pressing device.

To sum up, the film laminator disclosed in the present invention is equipped 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 parts or the two flattening parts are close to each other, the first inflatable ring and the second inflatable ring are attached to each other, so that the space between the two film-pressing parts or the two flattening parts remains airtight. Taking the inflatable sealing member disposed between the two applanation parts as an example to further illustrate, since the first inflatable ring and the second inflatable ring can be in an uninflated state before forming an airtight space, the two applanation parts can not be inflated when they are close to each other. The inflatable sealing member has a larger stroke due to interference, which helps the flattener to push the laminated semi-finished product with a thinner thickness. Moreover, the feed end and discharge end of the planar pressurizing device can have larger openings to allow the transport film and laminated semi-finished products to pass through without interfering with the inflatable sealing member, thereby contributing to the miniaturization of the planar pressurizing device. In addition, both the first inflatable ring and the second inflatable ring are flexible and can closely adhere to the conveying membrane, which helps to increase the airtightness of the enclosed space.

Furthermore, the film laminator disclosed in the present invention can also be configured with a sealing ring, which is disposed in the groove, and the groove can be filled with gas to push the sealing ring to protrude from the groove. A part of the sealing ring protruding from the groove can keep the airtight space between the two film pressing parts of the film pressing device and/or between the two flattening parts of the planar pressing device in an airtight state. At this time, the confined space can be decompressed by negative pressure suction, thereby improving the yield rate of the laminator and the quality of the lamination.
