Description

Technical Field

[0001] The invention relates to the technical field of vacuum winding coating, in particular to an arc-shaped roller vacuum sheathed flexible tube process device. Background Art

[0002] The core component of the winding roller system of vacuum winding coating equipment, such as winding magnetron sputtering and winding evaporation, is the arc roller used to flatten BOPP or PET film. At present, the arc roller mainly includes two types: rubber surface arc roller and Teflon sleeve arc roller. The Teflon sleeve arc roller is a rubber surface arc roller with a layer of Teflon sleeve. However, the current arc roller suit flexible tube process, such as arc roller suit Teflon sleeve, is basically heat-shrinked or cold-assembled in the atmospheric environment. The heat-shrinking and cold-assembly process will inevitably retain air between the Teflon sleeve and the rubber surface, that is, there will be more or less small bubbles between the Teflon sleeve and the rubber surface. At this time, if used in a vacuum environment, during the vacuum process, small bubbles will rapidly expand and grow due to the change in air pressure inside and outside the Teflon sleeve, causing the arc roller surface of the Teflon sleeve to be seriously deformed until the flattening effect is completely lost. The existing method to solve this problem is usually to apply a layer of glue between the Teflon sleeve and the rubber surface to bond the Teflon sleeve and the rubber sleeve together, which can reduce the generation of bubbles and inhibit the expansion of bubbles to a certain extent, but this method cannot solve the bubble problem from the root, and due to the presence of glue, it is difficult to completely remove the glue residue after the life of the Teflon sleeve expires, and a new Teflon sleeve cannot be replaced. Summary of the invention

[0003] In order to solve the problem that a layer of glue is applied between the Teflon sleeve and the rubber surface in the prior art to make the Teflon sleeve and the rubber sleeve bonded together, the generation of bubbles can be reduced and the expansion of bubbles can be inhibited to a certain extent. However, this method cannot solve the bubble problem from the root, and due to the presence of glue, it is difficult to completely remove the glue residue after the life of the Teflon sleeve expires, and a new Teflon sleeve cannot be replaced. The present application provides an arc roller vacuum sleeve flexible tube process device, and the specific plan is as follows.

[0004] An arc roller vacuum suit flexible tube process device, comprising a vacuum chamber, an adjustable arc motion mechanism, a translation mechanism, and a sliding mechanism, wherein the vacuum chamber is used to form a vacuum environment, a sliding track is arranged in the vacuum chamber, the sliding mechanism is slidably connected to the sliding track and can slide back and forth on the sliding track, the sliding track is arranged along the length direction of the vacuum chamber, both ends of the vacuum chamber are open and used to connect a vacuum pumping device, the sliding mechanism can slide out of the vacuum chamber, the translation mechanism is slidably connected to the sliding mechanism, and the adjustable arc motion mechanism is installed on the translation mechanism; The adjustable arc motion mechanism includes a base frame, which is fixedly mounted on the translation mechanism. An arc roller is arranged on the base frame, and a Teflon sleeve and a sleeve assembly are arranged on the arc roller. The Teflon sleeve is arranged on the arc roller, and the sleeve assembly is arranged on the outside of the Teflon sleeve. The sleeve assembly is used to wrap the Teflon sleeve on the arc roller after heat shrinkage and deformation. A driving assembly is also arranged on the base frame, and the driving assembly is used to drive the sleeve assembly to move along the length direction of the arc roller.

[0005] By adopting the above technical scheme, the Teflon sleeve process is completed in a vacuum environment, which fundamentally solves the problem of bubbles caused by air retained between the Teflon sleeve and the roller surface of the arc roller, increases the flatness of the Teflon sleeve, improves the flattening effect, and increases the service life of the arc roller. At the same time, when the Teflon sleeve is damaged, it will not be affected by the glue to replace it. At the same time, a translation mechanism and a sliding mechanism are set, and personnel do not need to enter the vacuum chamber during disassembly and assembly, which improves the convenience of disassembly and assembly, and can also see the vacuum chamber space, thereby improving the vacuum efficiency.

[0006] Optionally, the sleeve assembly includes a heating unit, which is annularly sleeved on the outside of the Teflon sleeve, and is used to release heat to heat the Teflon sleeve.

[0007] By adopting the above technical solution, the sleeve assembly moves along the direction of the arc roller and continuously heats the Teflon sleeve, thereby achieving heat shrinkage of the Teflon sleeve, so that the Teflon sleeve can fit on the arc tube.

[0008] Optionally, the sleeve assembly also includes a heat insulation unit and a smoothing unit, the heat insulation unit is arranged between the smoothing unit and the heating unit, the smoothing unit is provided with a flexible pressure piece, the flexible pressure piece is used to press against the Teflon sleeve, and the heat insulation unit is used to prevent the heat of the heating unit from being transferred to the smoothing unit.

[0009] By adopting the above technical scheme, since the Teflon sleeve itself is a straight tube structure before heat shrinkage, and the arc roller is a curved tube structure, tiny wrinkles will be generated due to the shape difference after heat shrinkage. At this time, the flexible pressure piece on the smoothing unit can press against the Teflon sleeve to smooth out the tiny wrinkles, thereby improving the circular runout accuracy of the arc roller behind the sleeve. At the same time, a heat insulation unit is arranged between the smoothing unit and the heating unit. The heat insulation unit can reduce the heat of the heating component that affects the flexible pressure piece, thereby further improving the stability of the smoothing effect.

[0010] Optionally, a single arc-shaped adjustment mechanism is provided on both sides of the arc-shaped roller in the length direction, and the single arc-shaped adjustment mechanism comprises a left shaft seat and a right shaft seat, and the left shaft seat and the right shaft seat are respectively provided at both ends of the length direction of the base frame, and an arc-shaped adjustment shaft is provided between the left shaft seat and the right shaft seat; A positioning sleeve is arranged in the left shaft seat, the positioning sleeve is connected to the left shaft seat by screws, the arc-shaped adjustment shaft is connected to the positioning sleeve by screws, an arc-starting piece is arranged in the positioning sleeve, the arc-starting piece is slidably connected in the positioning sleeve, and the arc-starting piece is used to push the arc-shaped adjustment shaft to start arcing; A shaft sleeve is arranged in the right shaft seat, and the arc-shaped adjustment shaft is connected to the shaft sleeve by screws; A slider is slidably connected to the arc-shaped adjustment shaft, a connecting block is fixedly connected to the slider, and the connecting block is detachably connected to the sleeve assembly.

[0011] By adopting the above technical scheme, since the sleeve assembly is fixedly connected to the connecting block on the slider, the sleeve assembly can be guided by the arc-shaped adjusting shaft when it moves. The arc-shaped adjusting shaft needs to adjust the position of the arc-starting part before processing, and the arc-starting part presses the arc-shaped adjusting shaft to achieve arc starting. When starting the arc, it is necessary to correspond to the curvature of the arc roller. After arc starting, the slider can guide the sleeve assembly to move along the arc line of the arc tube when sliding, so that the Teflon sleeve can better fit the surface of the arc roller during the installation process, further improving the circular runout accuracy of the arc roller behind the sleeve.

[0012] Optionally, the driving assembly includes a gear and a rack, the gear is rotatably connected to the sleeve assembly, and the rack is fixedly arranged on the base frame, the gear and the rack are meshed with each other, and the sleeve assembly is also provided with a motor for driving the gear to rotate, and the driving shaft of the motor is connected to the gear transmission.

[0013] By adopting the above technical solution, mutually meshing gears and racks are set, and the rotation of the motor drives the gear to move. Since the rack is fixed, the gear will move along the direction of the rack when it rotates, thereby driving the entire sleeve assembly to move and realize the driving of the sleeve assembly.

[0014] Optionally, a ball head groove and an embedding groove are formed on a side of the gear away from the motor, the ball head groove is connected to the embedding groove, a universal ball head is arranged in the ball head groove, the universal ball head can enter the ball head groove laterally through the embedding groove, the universal ball head can be confined in the ball head groove after rotating in the ball head groove, the inner side of the universal ball head is detachably connected to the driving shaft of the motor and can swing on the driving shaft, and the outer side of the universal ball head is detachably connected to the gear.

[0015] By adopting the above technical solution, the universal ball head can only be embedded from the side of the gear away from the motor, and the direction needs to be adjusted to extend into the embedding groove. After the whole is embedded, it can be embedded in the ball head groove only after rotation. At this time, after the universal ball head is connected to the drive shaft, it cannot be removed from the gear because the rotational freedom is limited. After the universal ball head and the gear are connected again, the gear can rotate under the drive of the universal ball head, and the gear can also swing along the universal ball head. Due to the curvature of the arc roller, different heights are prone to occur during the driving process. However, due to the setting of the universal ball head, the gear can swing within a certain range and can keep in contact with the rack during movement, reducing the situation of tooth hitting when the gear moves along the arc on the rack.

[0016] Optionally, a top screw hole is provided on the universal ball head, and a through hole corresponding to the shape of the top screw hole is provided on the gear, and the through hole is used for the top screw to extend into the top screw hole connected to the universal ball head.

[0017] By adopting the above technical solution, a top screw hole is opened on the universal ball head and a corresponding through hole is opened on the gear, which can improve the convenience of connecting the universal ball head and the gear. Opening such a through hole at a specific position will not affect the meshing of the gear and the rack, thereby improving the stability of the drive.

[0018] Optionally, an arc-starting groove is provided at a center position of the axis of the arc-shaped adjusting shaft, and the arc-starting groove is provided along a circumferential direction of the arc-shaped adjusting shaft.

[0019] By adopting the above technical solution, an arc starting groove is opened at the center of the arc-shaped adjustment shaft, and the stress at the arc starting groove is concentrated. Therefore, after arc starting, the arc line of the arc-shaped adjustment shaft will be centered on the opposite side.

[0020] Optionally, a through slot is opened in the middle of the arc-shaped adjustment shaft, and the through slot passes through the arc-shaped adjustment shaft. The through slot divides the arc-shaped adjustment shaft into left and right parts. A positioning pin is also provided on the arc-shaped adjustment shaft, and the positioning pin passes through the through slot and connects the left and right parts of the arc-shaped adjustment shaft.

[0021] By adopting the above technical solution, a through groove is opened in the middle of the arc-shaped adjustment shaft, which can reduce the resistance generated during arc starting. At the same time, a positioning pin is set. When the arc starting piece starts the arc, the arc-shaped adjustment shaft on one side can drive the arc-shaped adjustment shaft on the other side to start the arc, so that the arc starting can proceed normally.

[0022] Optionally, a semicircular key is further provided on the left shaft seat, and the semicircular key is used for detachable connection with the positioning sleeve.

[0023] By adopting the above technical solution, the semicircular key can play the same function as the screw, and realize axial positioning between the arc-shaped adjustment shaft and the positioning sleeve.

[0024] In summary, this application has at least the following beneficial effects: 1. The present application solves the problem that a layer of glue is applied between the Teflon sleeve and the rubber surface under the prior art to bond the Teflon sleeve and the rubber sleeve together, which can reduce the generation of bubbles and inhibit the expansion of bubbles to a certain extent. However, this method cannot solve the bubble problem from the root, and due to the presence of glue, it is difficult to completely remove the glue residue after the life of the Teflon sleeve expires, and it is impossible to replace a new Teflon sleeve. The present application fundamentally solves the problem of air retention between the Teflon sleeve and the roller surface of the existing Teflon sleeve arc roller by carrying out a sleeve flexible tube process in a vacuum environment, and also reduces the application of glue. After the life of the Teflon sleeve expires, the Teflon sleeve can be removed and the sleeve can be re-inserted, which improves the convenience of replacing the Teflon sleeve.

[0025] 2. The present application also provides an adjustable arc motion mechanism, which can be adjusted according to the arc curve of arc rollers with different arc heights, so that when the Teflon sleeve is installed, the sleeve assembly can move along the arc line of the arc roller, so that the Teflon sleeve can better fit the surface of the arc roller during the installation process. At the same time, a smoothing unit is designed to effectively flatten the fine circle generated when the flexible sleeve is wrapped around the arc roller, thereby improving the circular runout accuracy of the arc roller after the sleeve is installed.

[0026] 3. The present application also provides a smoothing mechanism and a sliding mechanism to form a two-level telescopic mechanism, which allows the adjustable arc motion mechanism to be moved out of the vacuum chamber as a whole, without the need for personnel to enter the vacuum chamber. This not only facilitates the disassembly and assembly of the arc roller each time, but also reduces the space of the vacuum chamber and improves the vacuuming efficiency.

[0027] 4. The present application also provides a gear that cooperates with the universal ball head, and the gear can rotate along the axis of the universal ball head. During the movement, the gear can be made to fit the rack more closely, thereby reducing the situation where the gear hits the rack when it moves along the arc of the arc roller.

A slider 531 is slidably connected to the arc adjustment shaft 53, and a connecting block 532 is fixedly connected to the slider 531, and the connecting block 532 is detachably connected to the sleeve assembly 4. In specific implementation, the slider 531 is sleeved on the arc adjustment shaft 53 and can slide along the arc adjustment shaft 53, and can guide the sleeve assembly 4 during the sliding process.

[0045] like Figure 5 and Figure 6 As shown, a positioning sleeve 511 is provided in the left shaft seat 51, and the positioning sleeve 511 is connected to the left shaft seat 51 by screws, and the arc-shaped adjustment shaft 53 is connected to the positioning sleeve 511 by screws.

One end of the screw sleeve 512 extends into the arc The arc-shaped adjustment shaft 53 is interfered with by the screw sleeve 512. Since the screw sleeve 512 is restricted by the arc-shaped adjustment shaft 53 when the adjustment knob 514 is turned, the screw sleeve 512 will move toward the arc-shaped adjustment shaft 53 under the drive of the adjustment knob 514, so that the arc-shaped adjustment shaft 53 can start the arc. Then, the arc-shaped adjustment shaft 53 only needs to be adjusted according to the arc of the arc roller 3, and the slider 531 on the arc-shaped adjustment shaft 53 can guide the sleeve assembly 4 to sleeve along the arc of the arc roller 3, further improving the fit during the sleeve.

A positioning pin 535 is also provided on the arc-shaped adjustment shaft 53, and the positioning pin 535 runs through the through slot 534 and connects the left and right parts of the arc-shaped adjustment shaft 53. In specific implementation, the through slot 534 can be opened by cutting the shaft on opposite sides to leave a small gap, or by directly hollowing out a through slot 534, which can reduce the arc starting resistance, and the positioning pin 535 can further ensure that the arc-shaped adjustment shaft 53 divided into two parts can drive each other to start the arc, and the arc-shaped adjustment shaft 53 is preferably made of carbon spring steel or alloy spring steel, which needs to have high elastic limit, fatigue limit, high toughness and hardenability to ensure that the arc-shaped adjustment shaft 53 can still maintain excellent elasticity and shape after repeated arc starting, such as 65Mn, 60Si2MnA and 50CrMnVA.

[0048] like Figure 4 and Figure 7 As shown, the driving assembly 44 includes a gear 45 and a rack 211, the gear 45 is rotatably connected to the sleeve assembly 4, the rack 211 is fixedly arranged on the base frame 21, the gear 45 and the rack 211 are meshed with each other, and the sleeve assembly 4 is also provided with a motor 441 for driving the gear 45 to rotate, and the driving shaft 442 of the motor 441 is in transmission connection with the gear 45. In specific implementation, the motor 441 is directly fixedly mounted on the sleeve assembly 4, and the gear 45 is mounted on the driving shaft 442 of the motor 441. Since the rack 211 is fixed, the gear 45 can move along the rack 211 when it rotates, and realizes back and forth movement according to the rotation direction of the gear 45.

[0049] like Figure 7 and Figure 8As shown, a ball head slot 451 and an embedding slot 452 are provided on a side of the gear 45 away from the motor 441. The ball head slot 451 is connected to the embedding slot 452. A universal ball head 46 is provided in the ball head slot 451. The universal ball head 46 can enter the ball head slot 451 laterally through the embedding slot 452. After the universal ball head 46 rotates in the ball head slot 451, it can be confined in the ball head slot 451. The inner side of the universal ball head 46 is detachably connected to the drive shaft 442 of the motor 441 and can swing on the drive shaft 442. The outer side of the universal ball head 46 is detachably connected to the gear 45. A top screw hole 461 is provided on the universal ball head 46, and a through hole 453 corresponding to the shape of the top screw hole 461 is provided on the gear 45. The through hole 453 is for the top screw to extend into the top screw hole 461 connected to the universal ball head 46. In specific implementation, Figure 7 The gear 45 is rotated toward the motor 441 on the side away from the motor 441 for the convenience of display. The universal ball head 46 needs to be inserted into the embedding groove 452 laterally when it is installed. After entering the ball head groove 451, it can be rotated to completely embed the universal ball head 46 in the ball head groove 451. At this time, it is more difficult to remove the universal ball head 46. At this time, the universal ball head 46 is matched and connected with the drive shaft 442. The matching connection method can be keyway matching, and then the top screw is inserted into the through hole 453 of the gear 45 through the top screw. The top screw is connected to the universal ball head 46 in the top screw hole 461 to complete the installation. At this time, the freedom of the ball head to grasp along the axis is limited, and the ball head cannot be separated from the gear 45. The gear 45 can rotate along the axial direction of the universal ball head 46. During the movement, the gear teeth of the gear 45 can be more closely fitted to the rack 211 teeth, reducing the situation of tooth hitting due to the need for the sleeve assembly 4 to move along an arc during movement. In addition, the width of the rack 211 is greater than the width of the gear 45 , and the gear 45 can be in full tooth contact with the rack 211 , further improving the traveling stability.

[0050] Working principle: When working, you need to install the arc roller 3 first. After installing the arc roller 3, start the single arc adjustment mechanism 5 on both sides to the height corresponding to the arc roller 3, then evacuate the vacuum chamber 1 to form a vacuum environment, drive the sleeve assembly 4 to move, and then the Teflon sleeve 31 heat shrink sleeve can be covered on the arc roller 3 along the arc roller 3. After the processing is completed, remove the arc roller 3 to complete the processing.
