Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is an overall configuration diagram of a vacuum roll coating apparatus according to a preferred embodiment of the present invention. As shown in fig. 1, the vacuum roll coating apparatus 100 of the present embodiment includes, in order from a left supply end to a right take-up end: the film coating device comprises an unreeling chamber 101, a first isolation chamber 103, a second isolation chamber 105, a first transition chamber 107, a first film coating chamber 109, a second transition chamber 111, a second film coating chamber 113, a third isolation chamber 115, a fourth isolation chamber 117 and a reeling chamber 119.
Wherein, the first to fourth isolation chambers 103, 105, 115 and 117 have the same modular structure; the first and second transition chambers 107 and 111 have the same modular structure, and the first and second coating chambers 109 and 113 may have the same module, different modules used according to different coating materials, or only cathodes disposed therein have different structures. Since each part, particularly the isolation chambers 103, 105, 115, 117 and the transition chambers 109, 113 have the same structure, a large-sized vacuum roll coating apparatus for coping with various complicated coating processes can be easily constituted by arbitrarily combining the same or different coating chambers 109, 113 as a necessary connection means.
And as the unit for connecting, isolation chamber and transition room, can use the common housing part, thus greatly reduce the installation of the apparatus, maintenance cost. Next, the structure of each isolation chamber will be described by taking the isolation chamber 103 as an example.
In this embodiment, fig. 2 and 3 are respectively a diagram showing a structure of an isolation chamber according to a preferred embodiment of the present invention. The isolation chamber 103 has a flat case 10301, and flanges 10303 as connection ports are provided at both ends of the isolation chamber, respectively, and a plurality of isolation chambers 103(105, 115, 117, etc.) can be connected by the flanges 10303 at both ends, or the isolation chamber 103 can be connected to another process module which is also provided with a flange which fits the flange 10303. A seat plate 10305 is arranged on the inner side of the flange 10303 at one end, and a notch 10307 is arranged on the seat plate 10305 and used for penetrating through the base material. On one side (upper side in the present embodiment) of the notch 10307, a valve shaft 10309 is provided in parallel with the notch 10307, and an elongated valve plate 10311 is provided along the valve shaft 10309 to be fixed to the valve shaft 10309. As a result, by actuating valve spindle 10309, valve plate 10311 can be pivoted and valve plate 10311 covers and closes notch 10307, thus sealing the other devices connected to isolation chamber 103 by flange 10303. In the present embodiment, the valve shaft 10309 is driven by a swing arm 10313 and a cylinder 10315 provided at one end thereof. The valve stem 10309 can be twisted by the cylinder 10315 to ensure the sealing property of the valve plate 10311 covering the notch 10307. In the use state, when the valve plate 10311 is rotated to cover the notch 10307 to achieve sealing, the base material penetrates through the notch 10307, and when the base material is textile fabric, on one hand, there is no fear that the base material of the textile fabric is damaged, and on the other hand, the sufficient contact length in the length direction of the textile fabric ensures the reliability of sealing to the maximum extent, and reduces vacuum leakage. The function of which will be described in detail later.
In the present embodiment, the transition chambers 109 and 113 are formed to have a flat box like the isolation chamber 103, and flanges are formed at both ends of the box to connect to the isolation chamber 103 or other devices. The difference from the isolation chamber 103 is that the transition chambers 109 and 113 are provided with a drive roller group and a tension roller group in series, which will be described in detail later.

When each module is vacuumized, the vacuum degree in the whole device can be maintained stably when the base material made of the textile fabric is subjected to film coating treatment.
FIG. 4 is a view for explaining the functions of the respective parts of the vacuum roll coating apparatus according to the preferred embodiment of the present invention. In fig. 4, the housings of the respective modules shown in fig. 1 are omitted, and only functional portions are shown. Any treatment process can be obtained by modularly combining the modularized isolation chamber, the transition chamber, the coating chamber and the winding and unwinding chamber.
As shown in fig. 4, the drive roller groups 203, 205, 215, 217 are roller groups provided in the isolation chambers 103, 105, 115, 117, respectively; the drive roller group 207A and the tension roller group 207B are roller groups provided in the transition chamber 107, and the drive roller group 211A and the tension roller group 211B are roller groups provided in the transition chamber 111; the unwinding roller 201 is arranged in the unwinding chamber 101; the wind-up roller 219 is disposed in the wind-up chamber 119. Fig. 5 is a block diagram of a control module of the vacuum roll coating apparatus according to the present embodiment. The control unit 301 controls the operations of the take-up and pay-off rolls 201 and 219, the roll groups, and the coating rolls through the bus 303. The operation principle of the vacuum roll coating apparatus 100 of the present embodiment will be described in detail below.
[ START-UP AND OPERATION ]
When the substrates are mounted on the unwinding rollers 201 and 219, respectively, it is prepared to start the supply of the substrate from the unwinding roller 201 and the recovery of the substrate from the winding roller 219, and before the substrate is subjected to the coating process by the coating rollers 209 and 213, the control unit 301 controls the unwinding roller 201 and the winding roller 219 to rotate in opposite directions, respectively. The opposite direction in the present embodiment is not the direction in which the unwinding roller 201 and the winding roller 219 actually rotate, but the rotation direction in which both of them normally operate to perform supply and recovery. When the unwinding roller 201 and the winding roller 219 rotate in opposite directions, the mounted substrate to be processed is applied with a pretension force. At this time, the magnitude of the pretension is detected by the tension roller groups 207B and 211B in the transition chambers 107 and 111, and the pretension is set to a predetermined value.
Then, the control unit 301 controls the unwinding roller 201 and the winding roller 219, and the coating rollers 209 and 213 and the respective drive roller groups 203, 205, 207A, 211A, 215, and 217 to rotate at the same linear velocity, completing the startup. Before the start, the unwinding roll 201 and the winding roll 219 are rotated in opposite directions to apply a predetermined pre-tension to the base material, and therefore, when the roll groups are started to rotate forward at the same speed, a predetermined tension can be maintained from the beginning. Therefore, the substrate on the innermost layer of the winding roller 219 is kept flat, and the influence of wrinkle deformation on the substrate which is wound next and is subjected to film coating treatment due to uneven winding during starting is avoided.
The control unit 301 receives the tension information detected by the tension roller sets 207B and 211B, and controls the rotation speed of each driving roller set and the coating roller according to the information, so as to ensure that the tension of the surface of each part of the base material is uniform from unreeling to reeling. Thereby, the thickness of the plating film on the surface of the substrate can be controlled well. In particular, in the present embodiment, when a base material made of a textile fabric is treated and the base material is coated in the coating chambers 209 and 213, if the tension of the base material is not uniform, the depth of penetration of the coating film into the base material and the uniformity change, and the texture of the base material after coating is not uniform, which seriously affects the usability of the base material and the like, and deteriorates the yield.
The transition chambers 107 and 111 are respectively arranged in front of the coating rollers 209 and 213, and the tension rollers 207B and 211B of the transition chambers detect the tension of the base materials entering the coating chambers 109 and 113, so that the tension of the base materials entering the coating chambers 107 and 111 to be subjected to coating treatment can be actively adjusted in time, and real-time control is realized. And by arranging the tensioning roller sets 207B and 211B at the upstream sides of the coating rollers 209 and 213, the transmission error of a system can be effectively compensated, and the uniform tensioning force of the base material receiving the coating treatment can be kept.
On the other hand, closed loop control of the tension of the substrate receiving the coating process is achieved with the tension roller sets 207B, 211B also being used. Taking the tension roller set 207B as an example, when the detected tension of the tension roller set 207B is smaller than the threshold value, which indicates that the feeding speed of the base material is too high, the control module 301 controls the upstream driving roller sets 203, 205, 207A to reduce the feeding speed so as to ensure that the base material can continuously pass through the coating roller 209 at a constant speed and maintain a specified tension; conversely, when the tension roller set 207B detects a tension greater than the threshold, indicating that the substrate feed rate is too slow, the control module 301 controls the upstream drive roller sets 203, 205, 207A to increase the feed rate to ensure that the substrate continuously passes through the coating roller 209 at a constant speed while maintaining the specified tension. Similarly, the tension roller group 211B and the coating roller 213 control the rotation speed of the upstream drive roller group 211A based on the detection information of the tension roller group 211B, so that the substrate entering the coating chamber 113 maintains a predetermined tension, thereby maintaining a predetermined tension while continuously passing through the coating roller 213 at a constant speed. Therefore, the tension of the substrate in the coating process in each coating chamber 109 and 113 can be controlled independently by making the tension of the substrate in the coating process in each coating chamber 109 and 113 different.
Furthermore, the continuous substrates supplied to the coating chambers 109 and 113 can be subjected to different stages of coating processes at different tensions according to the requirements of different materials and specifications of the coating chambers 109 and 113. Therefore, the vacuum winding coating device 100 can complete various treatments of different specifications in the sequential winding and unwinding processes, and the adaptability is wider. In particular, as shown in this embodiment, by using the modularized isolation chambers 103, 105, 115, and 117, the transition chambers 107 and 111, and the coating chambers 109 and 113, it is possible to flexibly change a combination of a plurality of coating processes.
[ RECOVERY TREATMENT ]
In this embodiment, since the substrate is supplied, coated, and wound in the vacuum chamber, after a roll of the substrate is supplied, the roll of the unwinding chamber 101 and the winding chamber 119 need to be replaced by breaking the vacuum, and the process can be resumed by performing the vacuum again. The flow of the recovery processing in the present embodiment will be described below.
When the supply of the substrate for one roll is completed to prepare for replacement, first, in step S601, the control unit 301 closes the valve plate 10311 in the upstream side isolation chambers 103 and 105 and the downstream side isolation chambers 115 and 117, and causes the valve plate 10311 to cover the notch 10307.
Then, in step S602, the chambers of the unwinding chamber 101 and the winding chamber 119 are controlled to be evacuated, and at this time, the coating chambers 109 and 113 are kept evacuated, and the evacuation state of each of the isolation chambers 103, 105, 115, and 117 may be kept or adjusted downward.
Next, in step S603, the doors of the unwinding chamber 101 and the winding chamber 119 are opened, and the substrate and the finished roll are replaced.
Next, in step S604, the unwinding chamber 101 and the winding chamber 119 are evacuated, and the vacuum state of each of the isolation chambers 103, 105, 115, and 117 is restored.
Then, in step S605, after the unwinding chamber 101 and the winding chamber 119 reach a predetermined degree of vacuum, the valve plate 10311 of each of the isolation chambers 103, 105, 115, and 117 is opened.
Finally, the start can be completed based on the above start mode, and the recovery processing is realized.
In the present embodiment, since the isolation chambers 103, 105, 115, and 117 are provided with the valve plate 10311 capable of covering the notch 10307, respectively, in the recovery operation, the transition chamber 107, the coating chamber 109, the transition chamber 111, and the coating chamber 113 between the isolation chambers 103 and 105 and the isolation chambers 115 and 117 are isolated by closing the notch 10307, and the vacuum state can be independently maintained, so that the substrate and the web in the unwinding chamber 101 and the winding chamber 119 can be replaced only by performing the breaking process on the unwinding chamber 101 and the winding chamber 119.
After the replacement is completed, only the unreeling chamber 101 and the reeling chamber 119 need to be vacuumized again, all chambers of the vacuum reeling coating device can be restored to the vacuum degree required by the operation, and the coating operation can be restored by opening each valve plate 10311 again.
Because the vacuuming needs a lot of processing time and consumes a lot of energy, the vacuum winding coating device 100 according to the present embodiment only needs to perform the operations of breaking and recovering the vacuum for the unwinding chamber 101 and the winding chamber 109 during the recovery operation, so the recovery operation time is greatly shortened, and the production efficiency of the device is improved. In addition, the waste of energy is reduced as much as possible, and the cost is reduced.
In addition, in the present embodiment, since the isolation chambers 103, 105, 115, and 117 and the transition chambers 107 and 111 are formed in a modular manner, when a plurality of sets of the upstream isolation chambers 103 and 105 and the downstream isolation chambers 115 and 117 are provided, partial sealing by the two-stage valve plate 10311 can be easily realized by the combined module, and thus, reliability of sealing is improved, and leakage of the vacuum degree in the coating chambers 109 and 113 is also reduced. In particular, even if the vacuum degree of the coating chambers 109 and 113 is maintained by the normal vacuum-pumping power, the vacuum degree of the coating chamber 109 is not excessively reduced after the replacement of the substrate and the coil is completed. Furthermore, since the isolation chambers 103, 105, 115, 117 form independent sealed spaces at the upstream and downstream ends of the coating chambers 109, 113, respectively, the vacuum degree of the isolation chambers 103, 105, 115, 117 can be maintained at a predetermined vacuum degree by a small power by using the gas passage 10323 as a vacuum line, and the vacuum degree of the isolation chambers 103, 117 from the upstream and downstream ends is increased stepwise toward the coating chambers 109, 113 in the middle, thereby further reducing the loss of the vacuum degree in the coating chambers 109, 113, and remarkably shortening the time for breaking and recovering the vacuum in the recovery operation.
In this embodiment, since the object to be processed of the vacuum roll coater is a flexible substrate, particularly a substrate made of a textile fabric, when the upstream and downstream ends are sealed with the substrate passing through the isolation chambers 103, 105, 115, and 117, the sealing effect is often poor. According to the present embodiment, when the seal structure is formed by turning the valve plate 10311 over the notch 10309, the base material is pressed against the seat plate 10305 by the valve plate 10311 at the notch 10309, and the thickness is compressed. At this time, a planar gap having a thickness smaller than that of the compressed base material is formed between the seat plate 10305 and the valve plate 10311, and the planar gap is formed only on the side where the base material is not sandwiched, so that the air leakage flow distance is long, the resistance is large, and the whole sealing performance is good. Compared with a valve in which the base material is tightly clamped from the upper side and the lower side of the base material transmission direction, the base material is the textile fabric, so that leakage holes are directly formed in gaps of the textile fabric, the gas circulation distance is short, the resistance is small, air flows through the gaps of textile fabric fibers when leaking at a high speed, the fiber structure at the sealing position is damaged, and the strength is reduced; on the other hand, in order to improve the sealing property, when the base material is clamped, the fabric fibers of the base material are damaged, and this causes a risk that the base material is broken due to the strength reduction of the damaged base material fibers when the recovery operation is resumed, and the continuous production cannot be smoothly performed, and the entire production line must be broken and recovered.
Although the preferred embodiments of the present invention have been described in detail, the above description is not intended to limit the scope of the present invention, and those skilled in the art can make various changes, modifications, deletions, and the like in addition to the above preferred embodiments, and these changes, modifications, and deletions all fall within the scope of the present invention, and the scope of the present invention should be determined based on the claims.
