Description

Technical Field

[0001] This invention relates to the field of cleaning device technology, and in particular to a membrane composite method. Background Technology

[0002] In the membrane composite process, it is necessary to combine the first membrane material and the second membrane material. The first membrane material is composed of multiple segments of sub-membrane material connected end to end. Any two adjacent sub-membrane materials are bonded together with adhesive tape. If the first membrane material and the second membrane material are directly combined, the adhesive tape will be present between the first membrane material and the second membrane material, affecting the composite quality between the first membrane material and the second membrane material.

[0003] In related technologies, before the first membrane material and the second membrane material are laminated, a peeling knife is used to remove the adhesive tape on the first membrane material.

[0004] However, because the tape and the first membrane material are tightly bonded, when the peeling knife peels off the tape from the first membrane material, the first membrane material will have more wrinkles due to the pulling of the tape, which will affect the subsequent bonding quality between the first membrane material and the second membrane material.

[0020] According to the membrane composite method of the present invention, cooling the tape on the first membrane material further includes the following steps:

[0021] Once the tape leaves the cooling zone, the cooling plate is driven away from the cooling zone.

[0022] According to the membrane composite method of the first aspect of the present invention, determining whether the tape leaves the cooling zone includes the following steps:

[0023] Obtain the preset length l2 of the cooling zone in the extension direction of the first membrane material;

[0024] Obtain the preset speed v of the first membrane material moving;

[0025] The timing starts when the tape enters the cooling zone. After a second time t2, the tape is judged to have left the cooling zone. The second time satisfies: t2 = l2 / v.

[0048] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0049] The following is for reference. Figures 1 to 5 The membrane composite method of the first aspect of this application will be described in detail.

[0050] refer to Figure 1 The membrane composite method according to embodiments of the present invention includes, but is not limited to, the following steps:

[0051] Step S100: Cool the tape 40 on the first membrane material 10 to reduce the adhesion between the tape 40 and the first membrane material 10;

[0052] Step S200: Remove the cooled adhesive tape 40 from the first membrane material 10;

[0053] Step S300: Composite the second membrane material 20 onto the first membrane material 10.

[0054] refer to Figure 5 The first membrane material 10 includes multiple segments of membrane material 11, which are connected end to end by adhesive tape 40. When laminating the first membrane material 10 and the second membrane material 20, if the second membrane material 20 is directly laminated onto the first membrane material 10, the adhesive tape 40 will get stuck between the first membrane material 10 and the second membrane material 20, thus affecting the lamination quality of the second membrane material 20 onto the first membrane material 10. If the adhesive tape 40 is scraped off the first membrane material 10 with a peeler before the second membrane material 20 is laminated onto the first membrane material 10, the adhesive tape 40 will pull the first membrane material 10 during the peeling process because the adhesion between the adhesive tape 40 and the first membrane material 10 is relatively tight, resulting in more wrinkles on the first membrane material 10, which also affects the lamination quality of the second membrane material 20 onto the surface of the first membrane material 10.

[0055] It is understood that in the membrane material lamination method of the present invention, the adhesive tape 40 on the first membrane material 10 is first cooled to reduce the adhesive force between the adhesive tape 40 and the first membrane material 10. Then, the cooled adhesive tape 40 on the first membrane material 10 is removed. Next, the second membrane material 20 is laminated onto the first membrane material 10. In the membrane material lamination method of this application, by cooling the adhesive tape 40 on the first membrane material 10, the adhesive force between the adhesive tape 40 and the first membrane material 10 can be reduced. When the adhesive tape 40 is subsequently removed, the tensile force of the adhesive tape 40 on the first membrane material 10 can be reduced, thereby reducing the generation of wrinkles on the first membrane material 10 and improving the lamination quality of the second membrane material 20 onto the first membrane material 10.

[0056] In some embodiments of the present invention, reference is made to Figure 2 Step S100 includes, but is not limited to, the following steps:

[0057] Step S110: Determine that the tape 40 on the first membrane material 10 has moved to the cooling zone;

[0058] Step S120: Drive the cooling plate 220 close to the cooling zone to cool the tape 40 in the cooling zone.

[0059] Understandably, after the tape 40 on the first membrane 10 moves to the cooling zone, the cooling plate 220 can approach and cool the tape 40 in the cooling zone to cool the tape 40, thereby reducing the adhesion between the tape 40 and the first membrane 10.

[0060] It is understandable that the cooling plate 220 has a large surface area, and the tape 40 can be cooled more thoroughly and evenly by the cooling plate 220.

[0061] In some embodiments of the present invention, reference is made to Figure 3 Step S110 includes, but is not limited to, the following steps:

[0062] Step S111: Determine that the tape 40 has moved to the detection area, wherein the detection area and the cooling area are separated by a preset distance l1;

[0063] Step S112: Obtain the preset speed v of the first membrane material 10 moving;

[0064] Step S113: Start timing when tape 40 enters the detection area. After the first time t1 has elapsed, determine that tape 40 has moved to the cooling area. The first time satisfies: t1 = l1 / v.

[0065] It is understandable that the tape 40 on the first membrane material 10 will move with the first membrane material 10 to pass through the detection area and the cooling area in sequence. The detection area and the cooling area are separated by a preset distance. After the tape 40 enters the detection area, the tape 40 moves with the first membrane material 10 for a short time and then moves into the cooling area for cooling.

[0066] It is understandable that the cooling plate 220 cools the tape 40 in the cooling zone. When the cooling plate 220 cools the tape 40, it will work with the limiting plate 230 to squeeze the tape 40. At this time, the tape 40 is located between the cooling plate 220 and the limiting plate 230, making it difficult for the sensor to detect the position of the tape 40. By setting a detection zone on one side of the cooling zone, the influence of the cooling plate 220 and the limiting plate 230 on the sensor can be reduced, enabling the sensor to accurately detect the position of the tape 40.

[0067] In some embodiments of the present invention, the detection area is the sensing area of ​​the color mark sensor 500, the tape 40 has a preset color, and step S111 includes, but is not limited to, the following steps:

[0068] Step S111a: When the color mark sensor 500 detects the preset color, it determines that the tape 40 has moved to the detection area.

[0069] It is understandable that the tape 40 has a preset color, and the preset color of the tape 40 is different from the color of the first film material 10. When the tape 40 moves into the detection area, the color mark sensor 500 can detect the preset color. Therefore, when the color mark sensor 500 detects the preset color, it means that the tape 40 has entered the detection area.

[0070] Specifically, the default color is red.

[0071] Understandably, red tape 40 is widely used, and staff can set the preset color detected by the color mark sensor 500 based on the actual color of tape 40.

[0072] In some embodiments of the present invention, reference is made to Figure 2 Step S100 also includes, but is not limited to, the following steps:

[0073] Step S130: Determine that the tape 40 has left the cooling zone, and drive the cooling plate 220 away from the cooling zone.

[0074] Understandably, after the tape 40 leaves the cooling zone, the cooling plate 220 needs to be driven away from the cooling zone to reduce the impact of the cooling plate 220 on the first film material 10 in the cooling zone.

[0075] In a further embodiment of the invention, reference is made to... Figure 4 Step S130 includes, but is not limited to, the following steps:

[0076] Step S131: Obtain the preset length l2 of the cooling zone in the extension direction of the first membrane material 10;

[0077] Step S132: Obtain the preset speed v of the first membrane material 10 moving;

[0078] Step S133: Start timing when tape 40 enters the cooling zone. After the second time t2, determine when tape 40 leaves the cooling zone. The second time satisfies: t2 = l2, v.

[0079] It is understandable that by allowing the tape 40 to remain in the cooling zone for a second time, each part of the tape 40 can be sufficiently cooled by the cooling effect of the cooling plate 220, thereby sufficiently reducing the adhesion between the tape 40 and the first film material 10.

[0080] It is understandable that if a CCD camera is used to detect whether the tape 40 has left the cooling zone, the detection by the CCD camera is easily interfered with by the cooling plate 220 and the limiting plate 230. In the film composite method of the present invention, the detection of whether the tape 40 has left the cooling zone is determined by the second time the tape 40 moves in the cooling zone, which can reduce the interference of the cooling plate 220 and the limiting plate 230 on the detection of the tape 40.

[0081] In some embodiments of the present invention, reference is made to Figure 1 The membrane composite method also includes, but is not limited to, the following steps:

[0082] Step S400: Composite the third membrane material 30 onto the surface of the first membrane material 10 that is away from the second membrane material 20.

[0083] The following is for reference. Figure 6 The composite device according to the second aspect of the present invention will be described in detail.

[0084] The composite apparatus provided according to a second aspect embodiment of the present invention is used to implement the membrane composite method provided in the first aspect embodiment of the present invention.

[0085] In some embodiments of the present invention, reference is made to Figure 6 The laminating device includes a frame 100, a first unwinding roller 110, a second unwinding roller 120, a cooling assembly 200, a cleaning assembly 300, and a laminating roller assembly 400. The first unwinding roller 110 is used to unwind a first film material 10; the second unwinding roller 120 is used to unwind a second film material 20; the cooling assembly 200 is disposed on the frame 100 and located on the moving path of the first film material 10, and is used to cool the tape 40 on the first film material 10; the cleaning assembly 300 is disposed on the frame 100 and located on the moving path of the first film material 10, and is used to remove the cooled tape 40 from the first film material 10; the laminating roller assembly 400 is disposed on the frame 100 and located on the common moving path of the first film material 10 and the second film material 20, and is used to laminate the second film material 20 onto the first film material 10 after the tape 40 has been removed.

[0086] It is understood that in the composite device of the present invention, a first film material 10 is wound on a first unwinding roller 110, and a second film material 20 is wound on a second unwinding roller 120. The first unwinding roller 110 is used to output the first film material 10, and the second unwinding roller 120 is used to output the second film material 20 to the composite roller group 400. When the first film material 10 passes through the cooling component 200, the cooling component 200 cools down the adhesive tape 40 on the first film material 10. Then, the first film material 10, carrying the cooled adhesive tape 40, moves to the cleaning component 300, where the cleaning component 300 peels off and removes the adhesive tape 40 from the first film material 10. After peeling off the adhesive tape 40, the first film material 10 moves to the composite roller group 400, where the second film material 20 is composited onto the first film material 10 under the action of the composite roller group 400.

[0087] Understandably, the cooling component 200 is configured so that when the tape 40 on the first membrane material 10 passes through the cooling component 200, the cooling component 200 can cool and reduce the temperature of the tape 40, thereby reducing the adhesion between the tape 40 and the first membrane material 10. This reduces the pulling force of the tape 40 on the first membrane material 10 when the subsequent cleaning component 300 removes the tape 40, thereby reducing the formation of wrinkles on the first membrane material 10 and improving the lamination quality of the second membrane material 20 on the first membrane material 10.

[0088] In a further embodiment of the invention, reference is made to... Figure 6 The laminating device also includes a third unwinding roller 130, on which a third film material 30 is wound. The third unwinding roller 130 is used to convey the third film material 30 to the laminating roller group 400. The laminating roller can laminate the third film material 30 onto the surface of the first film material 10 away from the second film material 20.

[0089] In some embodiments of the present invention, reference is made to Figure 6 The cooling assembly 200 includes a driver 210, a cooling plate 220, and a limiting plate 230. The cooling plate 220 and the limiting plate 230 are distributed in a vertical direction, and a cooling zone is formed between the cooling plate 220 and the limiting plate 230 to allow the first membrane material 10 to pass through. The driver 210 is connected to the cooling plate 220 and is used to drive the cooling plate 220 to move closer to or away from the limiting plate 230.

[0090] Understandably, after the tape 40 on the first film 10 moves into the cooling zone, the driver 210 drives the cooling plate 220 to approach the limiting plate 230 to cool the tape 40 in the cooling zone. After the tape 40 follows the first film 10 out of the cooling zone, the driver 210 drives the cooling plate 220 away from the limiting plate 230.

[0091] In some embodiments of the invention, the removal component 300 includes a peeler for peeling the cooled tape 40 off the first film 10.

[0092] In some embodiments of the present invention, reference is made to Figure 6The composite device also includes a color mark sensor 500, a timer, and a controller. The controller is electrically connected to the color mark sensor 500, the timer, and the driver 210. The detection area of ​​the color mark sensor 500 is spaced apart from the cooling area by a preset distance l1. The first film material 10 moves at a preset speed v. The cooling area has a preset length l2 in the extension direction of the first film material 10. The color of the tape 40 is a preset color. When the color mark sensor 500 detects the preset color, the controller controls the timer to start the initial timing. When the initial timing t1 of the timer satisfies: t1 = l1 / v, the tape 40 enters the cooling area. Under the control of the controller, the driver 210 drives the cooling plate 220 to approach the limiting plate 230 to cool the tape 40 in the cooling area. At this time, the timer starts the second timing. When the second timing t2 of the timer satisfies: t2 = l2 / v, the tape 40 leaves the cooling area. Under the control of the controller, the driver 210 drives the cooling plate 220 away from the limiting plate 230.

[0093] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
