Description

Technical Field

[0001] The invention relates to the technical field of film winding devices, in particular to a winding device for producing amorphous film. Background Art

[0002] Amorphous film refers to a film material without a crystal structure and in an amorphous state. Unlike crystalline films, amorphous films do not have a regular lattice arrangement at the microscopic level, so its atomic arrangement is random or disordered. This amorphous state gives the film unique properties and applications in many fields of electronics, optics and materials science.

[0003] After the film is produced, it needs to be rolled up and stored using a winding device. The existing winding device uses a winding wheel to roll up the film. When one winding wheel has finished rolling up, it needs to be replaced with a new winding wheel. At this time, the cutting knife close to the winding wheel on the winding device will cut the film so that the winding wheel that has finished rolling up can make room for the new winding wheel. When replacing the new winding wheel, it is generally necessary to apply glue on the new winding wheel so that the film can be rolled up by the new winding wheel.

[0004] However, when a new take-up wheel is replaced in the existing take-up device, the cutting knife has not yet cut the film, so the new take-up wheel will come into contact with the film before the previous take-up wheel has been detached, and the glue on the new take-up wheel will continue to adhere to the film and then separate, causing the film to deform, affecting the film winding quality. In addition, the cutting knife is close to the take-up wheel, so that the film cut by the cutting knife will fold when it is wound up by the new take-up wheel, affecting the uniformity of film winding.

[0023] Refer to the following Figure 1-Figure 13 The invention will now be described as follows: a winding device for producing a crystal-free film.

[0024] A winding device for producing amorphous film, suitable for winding a film 300, comprises a frame 100, a rotating drum 110 is arranged on the frame 100, the rotating drum 110 can rotate around its own axis, a winding frame 200 is also arranged on the winding frame 200, a first winding roller 240 is rotatably arranged on the winding frame 200, the film 300 to be wound passes between the rotating drum 110 and the first winding roller 240, the first winding roller 240 is coated with glue to adhere to the film 300 so that the film 300 can be attached to the first winding roller 240, and because the film 300 is located between the first winding roller 240 and the rotating drum 110 and is wound by the first winding roller 240, the film 300 is wound between the first winding roller 240 and the rotating drum 110. 40 and the rotating drum 110 are clamped, so the rotation of the rotating drum 110 can drive the first winding roller 240 to rotate through the film 300, and the first winding roller 240 winds up the film 300. As the first winding roller 240 winds up more and more film 300, the first winding roller 240 on the winding frame 200 needs to be replaced with the second winding roller 250 to continue winding. When replacing the second winding roller 250, it is necessary to set an auxiliary switching frame 140 on the frame 100. The auxiliary switching frame 140 is rotatably set on the frame 100, specifically located at the two ends of the rotating drum 110, and the auxiliary switching frame 140 can replace the second winding roller 250 to the winding frame 200.

[0025] During the replacement process, the first winding roller 240 is about to be wound up, and at this time, the second winding roller 250 is driven by the auxiliary switching frame 140 to rotate above the drum 110 and contact with the film 300, and the second winding roller 250 and the first winding roller 240 rotate synchronously, and the outer periphery of the second winding roller 250 is coated with a first glue 251 and a second glue, and the adhesion of the first glue 251 is greater than the adhesion of the second glue 252, and the second glue 252 is located in front of the first glue 251 in the rotation direction of the second winding roller 250. When the film 300 contacts the outer periphery of the second winding roller 250, the film 30 0 contacts the second glue 252 and the first glue 251 on the second winding roller 250 in sequence. The second glue 252 on the second winding roller 250 contacts the film 300 first, and then the first glue 251 contacts the film 300. Since the adhesion of the first glue 251 is greater than the adhesion of the second glue 252, it is assumed that the second glue 252 can be detached from the second winding roller 250, while the film 300 adhered to the first glue 251 cannot be detached from the second winding roller 250. Therefore, the film 300 will first be detached from the second glue 252 and the detached portion will be adhered to the second glue 252. Fig.11As shown, the second glue 252 can be partially attached to the film 300, so that after the film 300 is cut, the glue attached to the cut end of the film 300 can adhere to the film 300 on the outer periphery of the first winding roller 240, thereby closing the film 300 of the first winding roller 240 and avoiding the cut film 300 to be scattered on the first winding roller 240, while the first glue 251 fixes the other cut part of the film 300 on the second winding roller 250, avoiding the operator to repeatedly apply glue.

[0026] In order to cut the film 300, a retractable cutting tool 220 is provided on the auxiliary switching frame 140. When the cutting tool 220 is extended toward the second winding roller 250, the film 300 can be cut. Fig.10 and Fig.11 As shown, the position of the cutting tool 220 after extension is just located in the area between the first glue 251 and the second glue 252. The cutting tool 220 cuts the portion of the film 300 that adheres to the second glue 252 without affecting the first glue 251 that fixes the film 300 on the second winding roller 250. A sensing component is also provided on the auxiliary switching frame 140. The sensing component can sense the stress state of the film 300. When the first glue 251 on the periphery of the second winding roller 250 adheres the film 300 to the second winding roller 250 and does not detach, the first winding roller 240 is still rotating because it has not detached from the rotating drum 110. At this time, the film 300 will be subjected to a pulling force, and the sensing component It is located on the auxiliary switching frame 140, and the sensing component is located between the first winding roller 240 and the second winding roller 250, and is located at the lower end of the film 300. When the first winding roller 240 continues to pull the film 300, the film 300 can squeeze the sensing component. When the film 300 is subjected to a force exceeding a preset value, it means that the film 300 at this time has left the area coated with the second glue 252 and has come to the area of ​​the first glue 251. Since the first glue 251 fixes the film 300, the film 300 is pulled, and the sensing component promptly senses that the film 300 is pulled, so the cutting tool 220 promptly extends to cut the film 300 to prevent the film 300 from being deformed due to excessive force.

[0027] Specifically, the induction assembly of the present invention includes an induction roller 170 and a sliding block 160. There are two sliding blocks 160. The two sliding blocks 160 are respectively slidably arranged on the auxiliary switching frame 140. The sliding block 160 can move along the radial direction of the rotating wheel on the auxiliary switching frame 140, and the induction roller 170 is rotatably arranged on the sliding block 160. The outer periphery of the induction roller 170 is in rolling contact with the film 300. When the first winding roller 240 and the second winding roller 250 rotate, the film 300 will pass through the outer periphery of the induction roller 170. Therefore, when the force condition of the film 300 changes, the induction roller 170 will be pushed to move along the radial direction of the rotating cylinder 110, such as Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the first winding roller 240 rotates to pull the film 300, and the film 300 pulls the second winding roller 250. Since the film 300 is adhered by the first glue 251, the film 300 at this time will exert a downward force on the sensing roller 170, that is, the sensing roller 170 moves along the radial direction of the rotating drum 110 toward the axis of the rotating drum 110. When the sensing roller 170 moves a preset distance, the cutting tool 220 extends to cut the film 300. At this time, the cutting tool 220 extends toward the second winding roller 250, and the extended position is located at the first glue 251 of the second winding roller 250, so that when the film 300 is cut, the part outside the first glue 251 is just cut, so that when the film 300 is cut, no excess film 300 is folded when it is wound onto the second winding roller 250 after cutting, so as to ensure that the second winding roller 250 can wind the film 300 more evenly later.

[0028] At the same time, a second layer of glue 252 is adhered to the other end of the film 300 cut by the cutting tool 220, so that the part of the film 300 can adhere to the film 300 of the first winding roller 240 after being completely wound up by the first winding roller 240, thereby preventing the end of the part of the film 300 from floating everywhere.

[0029] More specifically, an elastic member 162 is provided between the sliding block 160 and the auxiliary switching frame 140. The elastic member 162 in this embodiment is a spring. One end of the elastic member 162 is connected to the auxiliary switching frame 140, and the other end of the elastic member 162 is connected to the sliding block 160. The setting of the elastic member 162 can enable the sensing roller 170 to reset when no force is applied, and can enable the sensing roller 170 to have a force to resist the downward pressure of the film 300. A distance sensor (not shown in the figure) can be installed on the auxiliary switching frame 140. The distance sensor detects the distance that the sensing roller 170 pushes the elastic member 162 to compress, that is, It can reflect the stress condition of the film 300, that is, the greater the compression degree of the elastic member 162, the greater the stress on the film 300, and the smaller the compression degree of the elastic member 162, the smaller the stress on the film 300. The preset distance is set to drive the cutting tool 220 to cut the film 300 under the premise of ensuring that the film 300 does not deform. When the film 300 begins to compress the elastic member 162, it means that the first glue 251 on the outer periphery of the second winding roller 250 begins to pull the film 300, and at this time the cutting tool 220 cuts the film 300, that is, the cutting time of the cutting tool 220 can be accurately obtained, and the film 300 can also be accurately cut.

[0030] It should be noted that, in order to ensure that the induction roller 170 can move along the radial direction of the rotating cylinder 110, a guide frame 150 is provided on the auxiliary switching frame 140, and a guide hole is opened on the guide frame 150, and the guide hole extends along the radial direction of the rotating cylinder 110. A guide rod 161 is also provided on the sliding block 160, and one end of the guide rod 161 is fixedly connected to the sliding block 160, and the other end of the guide rod 161 is inserted into the guide hole, and the end of the guide rod 161 located in the guide hole is connected to the elastic member 162, so as to Fig.12 and Fig.13 As shown, there are two guide rods 161 and two guide holes in this embodiment, so when the sensing roller 170 is squeezed by the force of the film 300 to squeeze the sliding block 160, the sliding block 160 can move radially along the rotating cylinder 110 through the guiding action of the guide rods 161 and the guide holes.

[0031] In a further embodiment, the cutting tool 220 of the present invention is telescopically arranged near the second winding roller 250, such as Fig. 9 and Fig.10As shown, the cutting tool 220 is specifically located on the auxiliary switching frame 140 and is close to one end of the second winding roller 250. A telescopic cylinder 230 is provided on one end of the cutting tool 220. When the telescopic cylinder 230 is extended or retracted, it can drive the cutting tool 220 to extend or shorten. When the force applied by the film 300 to the induction roller 170 does not reach a preset value, the telescopic cylinder 230 is in a shortened state. When it is necessary to cut the film 300, the telescopic cylinder 230 quickly extends to drive the blade of the cutting tool 220 to cut the film 300. After the cutting is completed, the telescopic cylinder 230 shortens and resets to prepare for the next cutting of the film 300.

[0032] In a further embodiment, in order to enable the winding frame 200 to drive the first winding roller 240 to separate from the rotating drum 110, the winding frame 200 is hinged to the frame 100, such as Figure 1 As shown, the bottom end of the winding frame 200 is hinged on the frame 100, and a groove is provided on the top of the winding frame 200, which can accommodate the two ends of the first winding roller 240, and a hydraulic cylinder 210 is also provided on the winding frame 200, one end of the hydraulic cylinder 210 is hinged on the frame 100, and the other end of the hydraulic cylinder 210 is hinged on the winding frame 200. When the hydraulic cylinder 210 is extended or shortened, it can push the winding frame 200 to rotate around the position hinged with the frame 100, and the winding frame 200 can drive the winding roller to separate from the rotating drum 110. For example, when the hydraulic cylinder 210 is in a shortened state, the groove at the top of the winding frame 200 is close to the rotating drum 110, the first winding roller 240 is located in the groove, and the outer periphery of the first winding roller 240 rolls in contact with the film 300, and the film 300 rolls in contact with the rotating drum 110, so when the rotating drum 110 rotates, it can drive the film 300 to be wound on the first winding roller 240. As more and more film 300 on the first winding roller 240 is wound, the overall diameter of the first winding roller 240 gradually increases. At this time, the hydraulic cylinder 210 on the winding frame 200 gradually extends to adapt to the first winding roller 240 with a gradually increasing diameter. 0. After the cutting tool 220 cuts the film 300, the first winding roller 240 on the winding frame 200 is wound up, and the hydraulic cylinder 210 begins to extend so that the winding frame 200 drives the wound up first winding roller 240 away from the rotating drum 110. At this time, the winding roller stops rotating after separating from the rotating drum 110. After the operator removes the first winding roller 240, the hydraulic cylinder 210 shortens and resets again to drive the winding frame 200 to reset. At this time, the auxiliary switching frame 140 drives the second winding roller 250 to approach the winding frame 200. The second winding roller 250 is re-positioned on the winding frame 200 and continues to wind up the film 300.

[0033] Specifically, a driving assembly is provided on the frame 100 in this embodiment, and the driving assembly can drive the rotating drum 110 to rotate and can also drive the auxiliary switching frame 140 to rotate. The driving assembly includes a first driving motor 120 and a second driving motor 180. The first driving motor 120 is fixedly arranged on one side of the frame 100. The rotating shaft of the first driving motor 120 is connected to the rotating shaft of the rotating drum 110 through a first belt 130. The rotation of the first driving motor 120 drives the rotating drum 110 to rotate. Figure 4 shown.

[0034] The second driving motor 180 is fixed on the other side of the frame 100. Figure 2 and Figure 3 As shown, the rotating shaft of the second driving motor 180 is drivingly connected to the auxiliary switching frame 140, and when the second driving motor 180 rotates, it can drive the auxiliary switching frame 140 to rotate around the rotating shaft.

[0035] More specifically, Figure 3 As shown, the auxiliary switching frame 140 is coaxially and fixedly connected with a transmission wheel 141 at the rotation center, and the rotating shaft and the transmission shaft of the second drive motor 180 are driven by the second belt 190. Therefore, when the second drive motor 180 rotates, the second drive motor 180 drives the auxiliary switching frame 140 to rotate, thereby driving the second winding roller 250 and the winding frame 200 to move.

[0036] It should be noted that if Figure 3 As shown, the auxiliary switching frame 140 is provided with a clamping claw 142, which can clamp the two ends of the second winding roller 250, and its function is similar to the groove on the winding frame 200, but the clamping head 143 on the left side of the clamping claw 142 on the auxiliary switching frame 140 is hinged on the auxiliary switching frame 140, and a torsion spring is provided at the hinge shaft so that the clamping head 143 can clamp the two ends of the second winding roller 250. When the auxiliary switching frame 140 is rotated clockwise (with a rotation speed of 0.1mm to 0.2mm), the clamping head 143 on the left side of the clamping claw 142 on the auxiliary switching frame 140 is hinged on the auxiliary switching frame 140, and a torsion spring is provided at the hinge shaft so that the clamping head 143 can clamp the two ends of the second winding roller 250. Figure 3 When the auxiliary switching frame 140 rotates clockwise (clockwise as viewed from front to back), both ends of the second winding roller 250 will enter the grooves of the winding frame 200. As the auxiliary switching frame 140 continues to rotate clockwise, the clamp 143 will gradually open due to the abutment force of the second winding roller 250, thereby preventing the clamp 143 from getting stuck in the second winding roller 250 and causing the auxiliary switching frame 140 to be unable to continue to rotate clockwise.

[0037] The specific working process of a winding device for producing a non-crystalline film 300 provided by the present invention is described in combination with the above embodiments: The first drive motor 120 is started, and the first drive motor 120 drives the rotating drum 110 to rotate through the first belt 130. At this time, the hydraulic cylinder 210 is in a shortened state, and one end of the film 300 passes through the rotating drum 110 and the first winding roller 240 on the winding frame 200. The rotating drum 110 rotates to drive the film 300 to be wound on the first winding roller 240. As the rotating drum 110 continues to rotate, the rotating drum 110 drives the film 300 to be continuously wound on the first winding roller 240. The overall diameter of the first winding roller 240 gradually increases, and the hydraulic cylinder 210 on the winding frame 200 gradually extends to adapt to the first winding roller 240 with a gradually increasing diameter. When the first winding roller 240 is about to be wound, the second drive motor 180 is started, and the second drive motor 180 drives the auxiliary switching frame 140 to rotate through the second belt 190. When the auxiliary switching frame 140 rotates to the top of the rotating drum 110, the induction roller 170 is located at the lower end of the film 300, and then the second winding roller 240 is wound. The roller 250 is mounted on the clamping claw 142 of the auxiliary switching frame 140. The outer periphery of the second winding roller 250 is coated with a first glue 251 and a second glue 252. The second glue 252 is located in front of the first glue 251 in the rotation direction of the second winding roller 250, so that when the second winding roller 250 starts to rotate, the second glue 252 first contacts the film 300, and the second glue 252 first adheres to the film 300. When the first glue 251 adheres to the film 300, the second glue 252 is firstly adhered to the film 300. Since the first glue 251 has a strong adhesive force, when the first winding roller 240 rotates and pulls the film 300, the film 300 has a tendency to move downward on the sensing roller 170, and the sensing roller 170 moves downward to compress the elastic member 162. When the sensing roller 170 moves to the preset position, the telescopic cylinder 230 extends, and the telescopic cylinder 230 drives the cutting tool 220 to cut the film 300. The cutting position is just between the first glue 251 and the second glue 252. Fig.10 and Fig.11 As shown, after the cutting tool 220 has cut the film 300, a second layer of glue 252 is adhered to the cut end of the film 300, so that after the first winding roller 240 has been wound up, the ends of the film 300 can be adhered together, thereby completing the complete winding of the first winding roller 240, and then the hydraulic cylinder 210 on the winding frame 200 extends to push the winding frame 200 to rotate, and the winding frame 200 drives the first winding roller 240 away from the rotating drum 110.

[0038] After the operator removes the first winding roller 240, the hydraulic cylinder 210 is shortened and reset again. At this time, the second drive motor 180 drives the auxiliary switching frame 140 to rotate and then drives the second winding roller 250 to approach the winding frame 200. The two ends of the second winding roller 250 are located in the groove of the winding frame 200. The auxiliary switching frame 140 is reset after rotating one circle. Since the first glue 251 on the outer periphery of the second winding roller 250 adheres to the film 300, the rotating drum 110 is in rolling contact with the film 300, and the second winding roller 250 drives the other side of the film 300 to roll, and the film 300 is wound on the second winding roller 250. The subsequent replacement process of the third, fourth, and Nth winding rollers is the same as above and will not be described in detail.

[0039] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
