Abstract
Description
Technical Field
[0001] This application relates to the field of gloss enhancement film lamination technology, and in particular to a lamination machine for gloss enhancement film production. Background Technology
[0002] Brightness enhancement film is an optical film used to improve the brightness and contrast of display devices (such as LCD screens and LED backlight modules). Through special microstructure design (such as prisms and microlens arrays), it directs and concentrates scattered light, thereby enhancing the brightness of the front of the screen while reducing energy loss.
[0003] Existing gloss enhancement film production lamination equipment typically employs automated devices. The gloss enhancement film is placed on a conveyor roller and transported to a laminating machine for lamination. After lamination, it is then wound up by a take-up roller. However, during the conveying process, dust may adhere to the surface of the gloss enhancement film, affecting the quality of the gloss enhancement film during lamination and thus reducing the lamination efficiency of the equipment. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a laminating machine for producing brightness enhancement film, which solves the problem that dust may adhere to the surface of the brightness enhancement film during the transportation process, affecting the quality of the film during lamination and thus reducing the lamination efficiency of the device.
[0005] The above-mentioned objective of this application is achieved through the following technical solution: a laminating machine for producing brightness enhancement film, comprising a feeding component and a laminating machine body, wherein a dust removal chamber is provided between the feeding component and the laminating machine body, an inlet is provided on the side of the dust removal chamber near the feeding component, an outlet is provided on the side of the dust removal chamber near the laminating machine body, and a dust removal component for removing dust from the surface of the brightness enhancement film is provided inside the dust removal chamber.
[0006] Furthermore, the dust removal assembly includes a first power source, a second power source, a first electrode plate, a second electrode plate, a third electrode plate, and a fourth electrode plate. The first power source and the second power source are respectively fixedly installed on the top and bottom surfaces of the dust removal chamber. The two poles of the first power source are respectively fixedly connected to the first electrode plate and the second electrode plate. The two poles of the second power source are respectively fixedly connected to the third electrode plate and the fourth electrode plate. Two rotating components are provided inside the dust removal chamber, and the third electrode plate and the fourth electrode plate are respectively disposed on the two rotating components.
[0007] Furthermore, the distance between the first electrode plate and the feeding assembly is smaller than the distance between the second electrode plate and the feeding assembly, and the distance between the third electrode plate and the feeding assembly is smaller than the distance between the fourth electrode plate and the feeding assembly. The first electrode plate and the third electrode plate are located on the upper and lower sides of the dust removal chamber, respectively, and are directly opposite each other. The second electrode plate and the fourth electrode plate are located on the upper and lower sides of the dust removal chamber, respectively, and are directly opposite each other.
[0008] Furthermore, the negative terminal of the first power supply is fixedly connected to the first electrode plate, and the positive terminal of the first power supply is fixedly connected to the second electrode plate.
[0009] Furthermore, the negative terminal of the second power supply is fixedly connected to the third electrode plate, and the positive terminal of the second power supply is fixedly connected to the fourth electrode plate.
[0010] Furthermore, the rotating assembly includes a first motor and rotating shafts. The first motor is fixedly installed on the side wall inside the dust removal chamber, one end of the rotating shaft is fixedly connected to the output end of the first motor, and the other ends of the two rotating shafts are respectively fixedly connected to one side of the third electrode plate and the fourth electrode plate.
[0011] Furthermore, two dust removal components are provided on one side of the dust removal chamber, and they are symmetrically arranged. The dust removal components include a second motor and an antistatic brush. The second motor is fixedly installed on one side of the dust removal chamber, and the output end of the second motor is fixedly connected to the antistatic brush.
[0012] Furthermore, the distance between the dust removal component and the feed inlet is less than the distance between the dust collection component and the feed inlet.
[0013] Furthermore, the antistatic brush is made of a soft material.
[0014] In summary, this application includes at least one of the following beneficial technical effects: When using the device, the brightness enhancement film is placed on the feeding assembly, which then feeds it from the inlet into the dust collection chamber. The film is then transported to the laminating machine body through the outlet. While the film is in the dust collection chamber, the first power supply is activated. The two poles of the first power supply supply different types of charges to the first and second electrode plates, respectively, and the two poles of the second power supply supply different types of charges to the third and fourth electrode plates, respectively. This is because the first and third electrode plates are directly opposite each other, as are the second and fourth electrode plates. The charges on the electrode plates first adhere to the upper and lower surfaces of the brightness enhancement film, causing the dust on the surface of the film to carry charges. As the brightness enhancement film continues to be conveyed, when it passes between the second and fourth electrode plates, the charges carried on the second and fourth electrode plates are different from those on the first and third electrode plates. Therefore, the second and fourth electrode plates will adsorb the dust on the surface of the conveyed brightness enhancement film, effectively preventing poor bonding quality when the brightness enhancement film enters the laminating machine body for bonding, thus improving the bonding efficiency of the device.
[0015] When using the device, the first motor is a servo motor. If the device does not need to transmit the brightness enhancement film, the two first motors are started to rotate forward. The two first motors drive the two rotating shafts to rotate, thereby causing the third and fourth electrode plates to flip. After flipping, the first motors are stopped, and the first and second power supplies are turned off to stop powering the first, second, third, and fourth electrode plates. This causes the dust on the first, second, third, and fourth electrode plates to fall downwards under the influence of gravity. After the dust has fallen off, the first motor is started to reverse, causing the third and fourth electrode plates to flip back to their initial working state, effectively improving the working efficiency of the device.
[0016] When using the device to remove dust from the surface of the brightness enhancement film, two second motors are started, which drive two antistatic brushes to rotate, so that the upper and lower surfaces of the brightness enhancement film are initially dusted. The antistatic brushes are made of soft bristles to prevent scratching the surface of the brightness enhancement film. Furthermore, the antistatic brushes are antistatic during rotation to prevent friction and static electricity, thus improving the dust removal efficiency of the device. Attached Figure Description

[0019] The present application will be further described in detail below with reference to the accompanying drawings.
[0020] Example, refer to Figure 1 as well as Figure 2A laminating machine for producing brightness enhancement film includes a feeding assembly 1 and a laminating machine body 2. A dust removal chamber 3 is disposed between the feeding assembly 1 and the laminating machine body 2. The dust removal chamber 3 has an inlet 31 on the side near the feeding assembly 1 and an outlet 32 on the side near the laminating machine body 2. A dust removal assembly 4 for removing dust from the surface of the brightness enhancement film is disposed inside the dust removal chamber 3. The dust removal assembly 4 includes a first power supply 41, a second power supply 42, a first electrode plate 43, a second electrode plate 44, a third electrode plate 45, and a fourth electrode plate 46. The first power supply 41 and the second power supply 42 are respectively fixedly installed on the top and bottom surfaces of the dust removal chamber 3. The two poles of the first power supply 41 are respectively fixedly connected to the first electrode plate 43 and the second electrode plate 44, and the two poles of the second power supply 42 are respectively fixedly connected to the third electrode plate 45 and the fourth electrode plate 46. Two rotating assemblies 5 are disposed inside the dust removal chamber 3, and the third electrode plate 45 and the fourth electrode plate 46 are respectively disposed on the two rotating assemblies 5. The distance between the first electrode plate 43 and the feeding assembly 1 is less than the distance between the second electrode plate 44 and the feeding assembly 1. The distance between the third electrode plate 45 and the feeding assembly 1 is less than the distance between the fourth electrode plate 46 and the feeding assembly 1. The first electrode plate 43 and the third electrode plate 45 are located on the upper and lower sides of the dust removal chamber 3 respectively and are directly opposite each other. The second electrode plate 44 and the fourth electrode plate 46 are located on the upper and lower sides of the dust removal chamber 3 respectively and are directly opposite each other.
[0021] Reference Figure 1 as well as Figure 2 When using the device, the first electrode plate 43 and the second electrode plate 44 are respectively inserted into the inner side of the dust removal chamber 3. Then, the brightness enhancement film is placed on the feeding assembly 1, and the brightness enhancement film enters the dust removal chamber 3 through the feeding assembly 1 from the inlet 31. Then, the brightness enhancement film is transported to the laminating machine body 2 through the outlet 32. When the brightness enhancement film is in the dust removal chamber 3, the first power supply 41 is activated. The two poles of the first power supply 41 respectively pass different types of charges to the first electrode plate 43 and the second electrode plate 44, and the two poles of the second power supply 42 respectively pass different types of charges to the third electrode plate 45 and the fourth electrode plate 46. Because the first electrode plate 43 and the third electrode plate 45 are facing each other, the second electrode plate 44... The first electrode plate 43 and the third electrode plate 45 are directly opposite the fourth electrode plate 46. The charges on the first electrode plate 43 and the third electrode plate 45 are first attached to the upper and lower surfaces of the brightness enhancement film, respectively. This causes the dust on the surface of the brightness enhancement film to carry the charge. As the brightness enhancement film continues to be conveyed, when the brightness enhancement film passes between the second electrode plate 44 and the fourth electrode plate 46, the charges carried on the second electrode plate 44 and the fourth electrode plate 46 are different from the charges on the first electrode plate 43 and the third electrode plate 45. Therefore, the second electrode plate 44 and the fourth electrode plate 46 will adsorb the dust on the surface of the conveyed brightness enhancement film, effectively preventing poor bonding quality when the brightness enhancement film enters the laminating machine body 2 for bonding, and improving the bonding efficiency of the device.
[0022] Reference Figure 1 as well as Figure 2 The negative terminal of the first power supply 41 is fixedly connected to the first electrode plate 43, and the positive terminal of the first power supply 41 is fixedly connected to the second electrode plate 44. The negative terminal of the second power supply 42 is fixedly connected to the third electrode plate 45, and the positive terminal of the second power supply 42 is fixedly connected to the fourth electrode plate 46. When using the device, because negative ions have a faster migration rate and are more prone to corona discharge, dust on the surface of the brightness enhancement film first carries a negative charge, and then is attracted by the positive charges carried by the second electrode plate 44 and the fourth electrode plate 46, thus completing dust removal and improving the working efficiency of the device.
[0023] Reference Figure 1 as well as Figure 2 The rotating assembly 5 includes a first motor 51 and a rotating shaft 52. The first motor 51 is fixedly installed on the side wall inside the dust removal chamber 3. One end of the rotating shaft 52 is fixedly connected to the output end of the first motor 51, and the other ends of the two rotating shafts 52 are respectively fixedly connected to one side of the third electrode plate 45 and the fourth electrode plate 46. When using the device, the first motor 51 is a servo motor. If the device does not need to transmit the brightness enhancement film, by starting the two first motors 51 to rotate forward, the two first motors 51 drive the two rotating shafts 52 to rotate, thereby causing the three electrode plates 45 and 46 to flip. After flipping, the use of the first motors 51 is stopped, and by turning off the first power supply 41 and the second power supply 42, the power supply to the first electrode plates 43, 44, 45, and 46 is stopped. As a result, the dust on the first electrode plates 43, 44, 45, and 46 falls downward under the influence of gravity. After the dust has fallen off, the first motor 51 is started to reverse, causing the third electrode plates 45 and 46 to flip back to their initial working state, effectively improving the working efficiency of the device.
[0024] Reference Figure 1 Two dust removal components 6 are symmetrically arranged on one side of the dust removal chamber 3. Each dust removal component 6 includes a second motor 61 and an antistatic brush 62. The second motor 61 is fixedly installed on one side of the dust removal chamber 3, and its output end is fixedly connected to the antistatic brush 62. The distance between the dust removal component 6 and the feed inlet 31 is less than the distance between the dust removal component 4 and the feed inlet 31. The antistatic brush 62 is made of soft material. The antistatic brush 62 is detachably installed on the output end of the second motor 61. When using the device to remove dust from the surface of the brightness enhancement film, the two second motors 61 are started, and each of the two second motors 61 drives the two antistatic brushes 62 to rotate, thus performing preliminary dust removal on both the upper and lower surfaces of the brightness enhancement film. The soft bristles of the antistatic brush 62 prevent scratching the surface of the brightness enhancement film, and the antistatic properties of the antistatic brush 62 during rotation prevent static electricity generation, thereby improving the dust removal efficiency of the device.
[0025] Working principle: When using the device, the brightness enhancement film is placed on the feeding assembly 1, which then feeds the film from the inlet 31 into the dust removal chamber 3. The film is then transported to the laminating machine body 2 through the outlet 32. While the film is in the dust removal chamber 3, two second motors 61 are activated, each driving a separate anti-static brush 62 to rotate, thus performing preliminary dust removal on both the upper and lower surfaces of the film. Then, the first power supply 41 is activated, supplying power to the first electrode plate 43 and the second electrode plate 44 respectively. The second power supply 42 supplies negative and positive charges to the third electrode plate 45 and the fourth electrode plate 46 respectively. The charges on the first electrode plate 43 and the third electrode plate 45 first attach to the upper and lower surfaces of the brightness enhancement film respectively, so that the dust on the surface of the brightness enhancement film carries negative charges. Then the second electrode plate 44 and the fourth electrode plate 46 will adsorb the dust on the surface of the conveyed brightness enhancement film, effectively preventing poor bonding quality when the brightness enhancement film enters the laminating machine body 2 for bonding, and improving the bonding efficiency of the device.
[0026] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
