Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a film material continuous processing tank for carrying out continuous processing while conveying a film material through a submerged guide roller.

[0002]

[Prior art]

 A conventional continuous processing tank for continuously processing a film material is shown in FIGS. In FIG. 4, a driven roller 15 as a submerged guide roller is rotatably arranged in the tank body 1 containing the treatment liquid Q, and conveying rollers 10 and 20 are arranged above the driven roller 15. The film material F is stretched around the rollers 10, 15 and 20 as shown in the drawing, and is transported in the Y direction while circumventing the inside of the tank main body 1 to bypass it.

Since the driven roller 15 comes into contact with the film material F conveyed by the conveying roller 20 and is driven to rotate, its shafts 15P and 15P are supported by bearings 2B and 2B shown in FIGS. There is. Each bearing 2B is formed of synthetic resin or ceramic without using a metal material because the treatment liquid Q is a strong acid or a strong alkali, or when the treatment liquid Q is a plating liquid, there is metal precipitation, and the inside of the tank body 1 is not used. It is attached to the support members 2 and 2 which are erected on.

A discharge pipe 34 forming a filtrate circulating device 30P is installed above the driven roller 15 in the tank body 1. The filtrate circulation device 30P includes an overflow tank 1F, a pump 31, a filter (not shown), liquid circulation pipes 32 and 33, and the like.

In such a continuous processing tank, when the film material F is fed in the Y direction by the transport rollers 10 and 20, the film material F introduced into the processing liquid Q is turned around by the driven roller 15 which is in direct contact with the film material F. . Further, the treatment liquid Q is stirred by driving the filtrate circulation device 30P. Therefore, the film material F can be continuously subjected to the predetermined treatment with the treatment liquid Q. It is also possible to perform a plating process in which electrodes are arranged.

[0006]

[Problems to be solved by the device]

 However, according to the above-described conventional structure, there is a restriction on the dimensional fitting relationship between the driven roller 15 and the discharge pipe 34. When the driven roller 15 is taken out from the tank main body 1, not only the discharge pipe 34 but also the supporting members 2 and 2 must be taken out, so that a lot of effort and time are spent for maintenance and inspection, and the work is complicated. Further, since the supporting members 2 and 2 having the bearings 2B and 2B mounted thereon must be provided on both sides of the tank main body 1, the tank main body 1 becomes large and the cost is increased, and the consumption amount of the treatment liquid Q also increases. . Further, when the rotational resistance of the driven roller 15 increases due to the deterioration of the bearings 2B, 2B over time, the soft film material F is scratched or dented on its surface, resulting in poor quality.

In particular, when the film material is the FPC (Flexible Printed Circuit) material 100 shown in FIG. 7A, the FPC material 100 is extremely thin (for example, 25 μm), for example, extremely thin (for example, 1 μm) on the polyimide resin film 102. The copper foil 101 is formed by vapor deposition, or the resin 102 is coated on the copper foil 101. Further, in preparation for the FPC completion step, a resist 102R for the resin 102 and a resist 101R for the copper foil 101 are applied. Even when the resists 101R and 102R are integrally formed, the total thickness is about 100 μm.

In the ultra-thin FPC material 100, for example, the tension is 300 g and the speed is 0.3 to 1. Since it must be conveyed at 0 m / min, the driven roller 15 may not rotate smoothly due to an increase in rotational resistance. Then, there is a problem that the frictional resistance between the film material F and the driven roller 15 increases, and the transportation of the film material F itself stops.

An object of the present invention is to provide a small-sized continuous processing tank for film materials, which can perform high-quality processing continuously while smoothly transporting even ultra-thin film materials with low tension and which is easy to maintain and inspect. Especially.

[0010]

[Means for Solving the Problems]

 In the present invention, the submerged guide roller is rotated by the moving force of the film material. In order to achieve the above-mentioned object, it is constituted by an immovable fixed roller, and a liquid film layer of the processing liquid is formed between the roller peripheral surface and the film material so that they do not come into direct contact with each other.

That is, the film material continuous processing tank according to the present invention is a film material which continuously carries out a predetermined processing while conveying the film material downwardly through the submerged guide roller arranged in the tank body. In the continuous processing tank, the blind guide roller is fixed at a fixed position in the tank main body and has a plurality of small holes penetrating in and out on the peripheral surface in contact with the film material being conveyed. A liquid circulating means which is formed of a cylindrical member and which circulates the processing liquid from the inner side to the outer side of the small hole is provided in the tank main body. It is characterized in that it is formed so that a sufficient liquid pressure can be generated to form a liquid film layer between the film material and the film material.

[0012]

[Action]

 In the present invention having the above-mentioned configuration, when the liquid circulating means is driven, the processing liquid is supplied into the submerged guide roller and is ejected to the outside from the plurality of small holes. Then, since the liquid film layer is formed between the inner surface of the film material and the peripheral surface of the submerged guide roller which is in contact with the film material, the frictional resistance between the two can be minimized. Therefore, even an extremely thin film material can be smoothly conveyed and guided. In addition, since the treatment liquid after forming the liquid film layer flows in the tank body, that is, the liquid agitation is prompted, the activation is enhanced and high quality treatment can be performed. Furthermore, since the submerged guide roller does not need to rotate, it can be fixedly installed by, for example, suspending and holding it with a liquid circulation pipe, which facilitates maintenance and inspection, including taking it out of the tank body, and downsizing. And the cost can be reduced.

[0013]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In this continuous processing tank, as shown in FIGS. 1 to 3, the submerged guide roller 15 is formed from a cylindrical member 16 with a blind lid 15S having a plurality of small holes 17 and is fixed at a predetermined position in the tank main body 1. In addition, a liquid circulation means 30 for circulating the treatment liquid Q in the tank body 1 from the inside and outside of the small hole 17 to the outside is provided, and between the peripheral surface of the submerged guide roller 15 and the inner surface of the film material F. It is configured to form the liquid film layer QF shown in FIG.

In FIG. 1, a submerged guide roller 15 is fixedly provided at a predetermined position below the tank body 1, and conveying rollers 10 and 20 are provided above the liquid guide roller 15. The film material F is stretched around the carrying roller 10, the submerged guide roller 15, and the carrying roller 20, and is circumvented into the processing liquid Q, detoured and turned, and carried in the Y direction.

Here, the film material F is the FPC 100 (101, 102) described with reference to FIG. 7, is extremely thin with a thickness of 50 μm, and the width dimension W has a pattern 110 as shown in FIG. 8B. Depending on the width dimension, the width is set to be 250 mm wide so that only 3 to 10 or more pieces can be formed in parallel. The transport speed is 0.5 m / min and the tension is set to 300 g.

As shown in FIG. 2, the submerged guide roller 15 has a structure in which both sides of the hollow cylindrical member 16 are closed by blind lids 15S and 15S, and the outer diameter is an allowable bending diameter of the film material F. It is supposed to correspond to. Further, a large number of small holes 17 are formed on the peripheral surface of the cylindrical member 16 which is in contact with the film material F, that is, the peripheral surface of the lower half in FIGS. 1 and 3. Each small hole 17 penetrates the inside and the outside.

Since the submerged guide roller 15 may be fixedly provided in the tank body 1, the liquid circulation pipes 33, 33 are connected to the introduction pipes 18, 18 having the tips penetratingly attached to the blind lids 15S, 15S. However, the liquid circulation pipes 33, 33 are held by being supported by the tank edge portions 1B, 1B. Therefore, if the flanges 33F and 33F are separated, the submerged guide roller 15 can be taken out of the tank by pulling up the liquid circulation pipes 33 and 33, which facilitates maintenance and inspection. Further, since it is not necessary to dispose the conventional bearing (2B) and its holding member (2), the tank main body 1 can be downsized.

Next, the liquid circulating means 30 is means for jetting and circulating the processing liquid Q in the tank body 1 from the inside to the outside of each small hole 17, and in this embodiment, the overflow tank 1 F, shown in FIG. It is composed of a suction pipe 1P, a pump 31, a filter 32F, and liquid circulation pipes 32 and 33. Then, when the pump 31 is rotationally driven, sufficient liquid pressure is generated between the peripheral surface of the submerged guide roller 15 and the film material F being conveyed to form the liquid film layer QF shown in FIG. Supply into the middle guide roller 15.

Therefore, the film material F and the submerged guide roller 15 indirectly contact with each other via the liquid film layer QF. That is, since there is no direct contact, the frictional resistance does not increase even if the submerged guide roller 15 does not rotate. Therefore, even an extremely thin and wide (W) film material F 1 can be smoothly conveyed and guided with low tension and low speed. High quality processing can be performed without worrying about scratches or dents on the film material F.

Further, as shown in FIG. 1, the treatment liquid Q after forming the liquid film layer QF becomes an upward flow Qf and circulates in the tank to enhance the surface activation of the film material F. Therefore, it is not necessary to provide the conventional discharge pipe 34, and the complicated dimensional fitting relationship with the submerged guide roller 15 can be eliminated. Moreover, the ascending flow Qf flows while efficiently stirring the surface of the film material F, so that the processing capacity can be further enhanced.

Next, the operation of this embodiment will be described. In the state shown in FIG. 3, when the liquid circulating means 30 is driven, the processing liquid Q pressurized by the pump 31 is supplied into the submerged guide roller 15 (16) through the introduction pipes 18, 18. Then, it is ejected from the large number of small holes 17 to the outside. Therefore, since the liquid film layer QF is formed between the film material F and the peripheral surface, the film material F is not in contact with the submerged guide roller 15. Therefore, even if the submerged guide roller 15 does not rotate, the frictional resistance between the film material F and the roller 15 can be minimized, so that the film material F can be smoothly conveyed and guided with low tension and low speed. That is, the film material F can be smoothly conveyed in the Y direction shown in FIG.

Further, the treatment liquid Q that has become the liquid film layer QF then becomes an upward flow Qf and circulates in the tank 1 to enhance the activation of the surface of the film material F. Therefore, continuous processing can be performed with high efficiency. Moreover, since the film material F is not in contact with the submerged guide roller 15, the film material F is of high quality without fear of being scratched or dented.

In order to perform maintenance / inspection of the submerged guide roller 15, stop the conveying rollers 10 and 20 and the liquid circulating means 30, then remove the flanges 33F and 33F and pull up the liquid circulating pipes 33 and 33. The submerged guide roller 15 can be quickly and easily taken out of the tank body 1. Therefore, the work can be performed easily and safely.

According to this embodiment, however, the submerged guide roller 15 is fixed at a predetermined position in the tank body 1 and has a plurality of small holes penetrating in and out on the peripheral surface in contact with the film material F being conveyed. A liquid circulation means 30 is provided which is formed from a cylindrical member 16 with a blind lid 15S, 15S having a hole 17 and which jets and circulates the processing liquid Q in the tank body 1 from the inside of the small hole 17 to the outside. Since the liquid circulating means 30 is formed so as to be able to generate a liquid pressure sufficient to form the liquid film layer QF between the peripheral surface of the submerged guide roller 15 and the film material F being conveyed, It is possible to provide a small-sized and inexpensive continuous processing tank for film materials that can perform high-quality processing continuously while smoothly transporting even thin film materials with low tension and is easy to maintain and inspect.

Further, since the submerged guide roller 15 is formed of the hollow cylindrical member 16 with the blind lids 15S, 15S, the structure is simple, the cost is low, and the implementation is easy.

Further, since the liquid circulation means 30 may have almost the same configuration as the conventional filtrate circulation device 30P, the facility and economical burden is small.

Further, since the film material F and the peripheral surface of the submerged guide roller 15 are not in contact with each other via the liquid film layer QF, the friction resistance between the film material F and the submerged guide roller 15 is increased. You can clean up the problem. Therefore, the extremely thin and wide film material F can be transported with low tension, and the adaptability can be remarkably expanded.

Further, the treatment liquid Q after forming the liquid film layer becomes the ascending flow Qf that stirs the surface of the film material F, so that efficient treatment can be stably performed. It is more efficient than the conventional discharge pipe 34. Moreover, since it is not necessary to dispose the discharge pipe 34, the dimensional coupling relationship with the submerged guide roller 15 is simplified, and the freedom of layout can be increased.

Further, since the submerged guide roller 15 does not need to be rotated by a fixed type, the conventional bearings 2B, 2B and the supporting members 2, 2 can be wiped out, the tank main body 1 can be downsized, and the cost can be reduced. .

Further, since the liquid circulating means 30 can change the liquid pressure by the rotation speed of the pump 31, the liquid film layer QF can be reliably generated even if the property of the film material F changes. If the motor speed of the pump 31 is continuously variable by using an inverter or the like, the applicability can be further expanded.
