[0002] Currently, reflective paper lamination for Mini LED light panels is mostly performed during module assembly, which is technically challenging. Alternatively, during the actual lamination process, it relies primarily on manual lamination or simple jigs, resulting in high rates of poor lamination and low efficiency. Summary of the Invention

[0032] The roller carrier is controlled to continue rolling until the reflective paper of a set of LED light panels is bonded. Then, the vacuum adsorption holes on the roller carrier are stopped, and the LED light panels with the reflective paper bonded are placed on the conveyor belt.

[0033] A third aspect of this invention discloses a bonding device for bonding reflective paper to LED light panels, the bonding device comprising:

[0034] An LED light board carrier (2) carrying an LED light board (1) with the back of the LED light board facing upwards, and the LED light board carrier (2) being mounted on a conveyor belt (3);

[0035] A roller carrier (4) is set above the conveyor belt (3). The roller carrier (4) is composed of multiple carriers (41).

[0041] Optionally, the carrier (41) is also provided with a separate cavity. By controlling the closing or opening of the separate cavity, the carrier (41) corresponding to the separate cavity can stop adsorbing using the vacuum adsorption hole (10) or perform adsorption using the vacuum adsorption hole (10) when the vacuum adsorption is turned on.

[0042] Alternatively, the vehicle (41) may also be provided with reinforcing ribs (11);

[0045] A fourth aspect of this invention discloses a bonding device for bonding reflective paper to LED light panels, the bonding device comprising:

[0046] A roller carrier (4) is set above the conveyor belt (3). The roller carrier (4) is composed of multiple carriers. Each carrier has an LED light panel (1) with its back facing out.

When the roller carrier (4) identifies the Mark point on the reflective paper (7), the ion fan (5) is running. By pressing down the roller carrier (4), the LED light panel (1) on the carrier is made to adhere to the vacuum adsorption reflective paper carrier (6). The vacuum adsorption of the vacuum adsorption reflective paper carrier (6) is turned off, so that the reflective paper (7) adheres to the LED light panel (1).

[0050] Optionally, it may also include: adjusting the equipment;

[0051] The adjustment device is connected to the roller carrier (4). When the roller carrier (4) fails to identify the Mark point on the reflective paper (7), the adjustment device is used to adjust the position of the roller carrier (4) until the Mark point on the reflective paper (7) is identified.

[0052] Optionally, the carrier is also provided with a separate cavity.

During LED light panel production, the LED light panel and reflective paper are positioned on a conveyor belt and a roller carrier, respectively. Through the cooperation of the conveyor belt and roller carrier, when the roller carrier identifies a Mark point that determines the positions of the LED light panel and reflective paper, the LED light panel and the reflective paper to be bonded to it are determined to be in corresponding positions.

After bonding, the LED light panel with the bonded reflective paper is placed on the conveyor belt. In this embodiment, bonding is performed during LED light panel production, reducing operational difficulty.

Detailed Implementation

[0064] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] As the background technology shows, currently, reflective paper lamination for Mini LED light panels is mostly performed during module assembly, which is difficult to operate. Alternatively, during the actual lamination process, it mainly relies on manual lamination or simple jigs for direct lamination, resulting in high rates of poor lamination and low efficiency.

[0066] Therefore, this invention discloses a method for bonding reflective paper to LED light panels, and a bonding device for bonding reflective paper to LED light panels. Bonding reflective paper during the production of LED light panels effectively reduces operational difficulty. During bonding, the LED light panel and reflective paper are positioned on a conveyor belt and a roller carrier, respectively. Through the cooperation of the conveyor belt and the roller carrier, when the roller carrier identifies the Mark point that determines the positions of the LED light panel and the reflective paper, it is determined that the LED light panel and the reflective paper to be bonded to the LED light panel are in corresponding positions. Bonding is performed while the ion fan is running, controlling the roller carrier to bond the LED light panel and the reflective paper. After bonding is completed, the LED light panel with the bonded reflective paper is placed on the conveyor belt. The entire bonding process, performed while the ion fan is running, prevents the generation of static electricity, ensures high flatness of the bonded reflective paper, avoids wrinkles during bonding, and improves bonding yield and efficiency.

[0067] The embodiments of the present invention employ a combination of conveyor belts and roller carriers for reflective paper lamination, which further enables mass production.

[0068] For a detailed implementation process, please refer to the following specific embodiments.

[0069] like Figure 1 The diagram shown is a structural schematic of a bonding device for bonding reflective paper to LED light panels, as disclosed in an embodiment of the present invention. This bonding device operates based on a pre-set program, which can be specifically controlled by a controller. The bonding device includes: an LED light panel carrier 2, a conveyor belt 3, a roller carrier 4, a carrier, an ion fan 5, a vacuum adsorption hole 10, and a vacuum pump.

[0070] The LED light board carrier 2 carries the LED light board 1, with the back of the LED light board 1 facing upwards.

[0071] In one embodiment of the present invention, the LED light panel includes a Mini LED light panel.

[0072] The LED light panel carrier 2 is mounted on the conveyor belt 3.

[0073] The roller carrier 4 is positioned above the conveyor belt 3. The roller carrier 4 consists of multiple carriers, each of which has a reflective paper to be attached to the LED light panel 1.

[0074] The dimensions of the vehicle are adapted to the dimensions of LED light panel 1.

[0075] In other words, the size of the vehicle on the roller carrier 4 can be adjusted according to the size of the LED light panel 1. It should be noted that the large size is compatible with various small-sized LED light panels or Mini LED light panels.

[0076] For example, the size of the Mini LED light panel to be laminated with the reflective paper can be less than or equal to the size of the carrier 41, but cannot be greater than the size of the carrier.

[0077] The ion fan 5 is located on one side of the conveyor belt 3, with its outlet facing the roller carrier 4. When laminating the reflective paper, the ion fan 5 is in operation. Laminating while the ion fan is in operation can prevent the generation of static electricity, ensure the high flatness of the laminated reflective paper, avoid wrinkles during the lamination process, and improve the lamination yield and efficiency.

[0078] Vacuum adsorption holes 10 are provided on the carrier.

[0079] In one embodiment of the present invention, vacuum adsorption holes 10 are provided on the front side 8 and the back side 9 of the carrier.

[0080] The roller carrier 4 is connected to a vacuum pump.

[0081] During the actual bonding process, the LED light board carrier (2) carrying the LED light board 1 is conveyed to the roller carrier 4 directly below by the conveyor belt 3. When the roller carrier 4 identifies the Mark point on the LED light board 1, the vacuum pump is turned on while the ion fan 5 is running. The LED light board 1 is adsorbed and bonded to the reflective paper on the carrier 41 by the vacuum adsorption hole 10 on the carrier 41. After bonding is completed, the vacuum pump is stopped, and the LED light board 1 with the reflective paper bonded is placed on the conveyor belt 3.

[0082] In one embodiment of the present invention, the bonding device further includes an adjustment device.

[0083] The adjustment device is connected to the roller carrier 4. When the roller carrier 4 fails to recognize the Mark point on the LED light board 1, the adjustment device is used to adjust the position of the roller carrier 4 until the Mark point on the LED light board is recognized.

[0084] It should be noted that the adjustment device can be a controller, or a combination of a controller and a displacement adjustment device. If it is a controller, the controller stores a pre-set program to control the operation of the bonding device.

[0085] In one embodiment of the present invention, the carrier is further provided with a separate cavity. By controlling the closing or opening of the separate cavity, the carrier corresponding to the separate cavity can stop adsorbing using the vacuum adsorption hole 10 or perform adsorption using the vacuum adsorption hole 10 when the vacuum adsorption is enabled.

[0086] In one embodiment of the present invention, the vehicle is further provided with reinforcing ribs 11; the reinforcing ribs 11 can enhance the strength of the vehicle and make the vehicle flat and non-deformable.

[0087] In one embodiment of the present invention, the number of carriers is 6, and the number of LED light panel carriers 2 is 6.

[0088] In this embodiment of the invention, the number of the carrier and the LED light panel carrier 2 can be adjusted as needed.

[0089] Taking the bonding of reflective paper to a Mini LED light panel as an example, such as Figure 1 As shown, the roller carrier 4 has 6 carriers, and the conveyor belt 3 has 6 LED light panel carriers 2 (taking the Mini LED light panel with reflective paper as an example). Figure 1 The six LED light panel carriers shown are specifically Mini LED light panel carriers.

[0090] The following explanation uses the batch lamination of reflective paper on a group of 6 Mini LED light panels as an example:

[0091] When producing Mini LED light panels, the Mini LED light panels are placed face down on the Mini LED light panel carrier, and then the Mini LED light panel carrier is placed on the conveyor belt 3. The conveyor belt 3 then transports the Mini LED light panel carrier directly below the roller carrier 4.

[0092] When ion fan 5 is running:

[0093] Once the roller carrier 4 identifies the Mark point of the Mini LED light panel, it turns on the vacuum pump and uses the vacuum suction holes 10 on the front 8 and back 9 of the carrier to suction the Mini LED light panel on the conveyor belt 3 onto the corresponding carrier.

[0094] When the roller carrier 4 fails to recognize the Mark point of the Mini LED light panel, the roller carrier 4 adjusts its position according to the set program until the Mark point of the Mini LED light panel is recognized. Then, the vacuum pump is turned on, and the Mini LED light panel 1 on the conveyor belt 3 is adsorbed onto the corresponding carrier through the vacuum adsorption holes 10 on the front 8 and back 9 of the carrier.

[0095] After the Mini LED light panel is attached to the corresponding carrier, the Mini LED light panel is bonded to the reflective paper fixed on the carrier, at which point the front (light surface) of the Mini LED light panel faces upward.

[0096] The individual cavity of the carrier is closed by control, so that the carrier stops vacuum adsorption and the MiniLED light panel with the reflective paper bonded is placed on the conveyor belt 3.

[0097] The control roller carrier 4 rolls to the next Mini LED light panel carrier on the conveyor belt 3, and performs the Mark point recognition, adsorption, bonding and de-adsorption operation again, and so on, until a set of Mini LED light panels is identified, adsorbed, bonded and de-adsorbed.

[0098] A set of Mini LED light panels with reflective paper attached will be conveyed to the next process via conveyor belt 3.

[0099] In this embodiment of the invention, reflective paper lamination during LED light panel production effectively reduces operational difficulty. During lamination, the LED light panel and reflective paper are positioned on a conveyor belt and a roller carrier, respectively. The conveyor belt and roller carrier work together to determine the corresponding positions of the LED light panel and reflective paper when the roller carrier identifies the Mark point. Lamination is performed while the ion fan is running, controlling the roller carrier to achieve the lamination of the LED light panel and reflective paper. After lamination, the LED light panel with the reflected paper laminated is placed on the conveyor belt. The entire lamination process, conducted while the ion fan is running, prevents static electricity generation, ensuring high flatness of the laminated reflective paper, avoiding wrinkles during lamination, and improving lamination yield and efficiency. Furthermore, using a conveyor belt and roller carrier for reflective paper lamination enables mass production.

[0100] like Figure 2 The diagram shown is a flowchart illustrating a method for bonding reflective paper to an LED light panel according to an embodiment of the present invention. The method mainly includes the following steps:

[0101] S201: When producing LED light boards, place the LED light boards with the back side facing up on the LED light board carrier.

[0102] S202: The LED light panel carrier carrying the LED light panel is conveyed by a conveyor belt to the area directly below the roller carrier.

[0103] In S202, the roller carrier consists of multiple carriers, each of which has a reflective paper to be bonded to the LED light panel. The size of the carrier is adapted to the size of the LED light panel.

[0104] S203: When the roller carrier recognizes the Mark point on the LED light panel, execute S204.

[0105] S204: Perform bonding operation.

[0106] The bonding process includes:

[0107] When the ion fan is running, vacuum adsorption is activated. Using the vacuum adsorption holes on the roller carrier, the LED light panel is adsorbed and bonded to the reflective paper on the roller carrier. After bonding is completed, vacuum adsorption is stopped, and the LED light panel with the reflective paper bonded is placed on the conveyor belt.

[0108] The ion fan is located on one side of the conveyor belt, with its outlet facing the roller carrier.

[0109] In one embodiment of the present invention, it further includes:

[0110] When the roller carrier fails to recognize the Mark point on the LED light board, control the roller carrier to adjust its position until it recognizes the Mark point on the LED light board, and then perform the bonding operation.

[0111] In one embodiment of the present invention, multiple LED light panel carriers are grouped together, and the number of roller carriers is the same as the number of LED light panel carriers in a group. Each roller carrier is provided with a separate cavity.

[0112] In this embodiment of the invention, by controlling the closing or opening of individual cavities, the carrier corresponding to the individual cavity can stop adsorbing using the vacuum adsorption holes or perform adsorption using the vacuum adsorption holes when the vacuum adsorption state is activated.

[0113] When specifically implementing the bonding method disclosed in the embodiments of the present invention:

[0114] First, place each LED light panel with its back facing up on an LED light panel carrier to form a group of LED light panels to be covered with reflective paper.

[0115] Secondly, the LED light panel carrier carrying the LED light panel is conveyed by a conveyor belt to the area directly below the roller carrier.

[0116] Secondly, when the roller carrier identifies the Mark point on the LED light board, vacuum adsorption is activated while the ion fan is running. The LED light board is then adsorbed and bonded to the reflective paper on the roller carrier using the vacuum adsorption holes on the roller carrier.

[0117] Next, close the individual cavity on the carrier corresponding to the reflective paper that is bonded to the LED light panel, so that the LED light panel with the reflective paper bonded is placed on the conveyor belt.

[0118] Finally, the control roller carrier continues to roll until the reflective paper of the LED light panel assembly is applied, so that all the LED light panels with the reflective paper applied are placed on the conveyor belt.

[0119] In one embodiment of the present invention, the LED light board is a Mini LED light board, and the LED light board carrier is a Mini LED light board.

[0120] The LED light panel reflective paper bonding method disclosed in the above embodiments of the present invention can be specifically used in the above embodiments of the present invention. Figure 1 For details on the implementation process and principles of the publicly disclosed bonding device, please refer to the documentation for [link to documentation]. Figure 1 The description.

[0121] like Figure 3 The diagram shown is a structural schematic of another bonding device for bonding reflective paper to LED light panels, as disclosed in an embodiment of the present invention. This bonding device operates based on a pre-set program, which can be specifically controlled by a controller. The bonding device includes: a conveyor belt 3, a roller carrier 4, a carrier, an ion fan 5, a vacuum adsorption reflective paper carrier 6, reflective paper 7, and a vacuum pump.

[0122] The roller carrier 4 is positioned above the conveyor belt 3.

[0123] The roller carrier 4 consists of multiple carriers, and vacuum adsorption holes are provided on the carriers.

[0124] In one embodiment of the present invention, vacuum adsorption holes are provided on the front and back of the carrier.

[0125] Each carrier 41 has an LED light panel 1 with its back facing out, and the size of the carrier 41 is adapted to the size of the LED light panel 1.

[0126] In other words, the size of the vehicle on the roller carrier 4 can be adjusted according to the size of the LED light panel 1. It should be noted that the large size is compatible with various small-sized LED light panels or Mini LED light panels.

[0127] For example, the size of the Mini LED light panel to be laminated with the reflective paper can be smaller than or equal to the size of the carrier, but cannot be larger than the size of the carrier.

[0128] The ion fan 5 is located on one side of the conveyor belt 3, with its outlet facing the roller carrier 4. When laminating the reflective paper, the ion fan 5 is in operation. Laminating while the ion fan is in operation can prevent the generation of static electricity, ensure the high flatness of the laminated reflective paper, avoid wrinkles during the lamination process, and improve the lamination yield and efficiency.

[0129] The vacuum adsorption reflective paper carrier 6 adsorbs reflective paper 7. The vacuum adsorption reflective paper carrier 6 is set on the conveyor belt 3.

[0130] It should be noted that the release film on the reflective paper 7 has been removed beforehand.

[0131] During the actual bonding process, the vacuum adsorption reflective paper carrier 6 is conveyed to the area directly below the roller carrier 4 via the conveyor belt 3. When the roller carrier 4 identifies the Mark point on the reflective paper 7, the LED light panel 1 on the carrier is bonded to the vacuum adsorption reflective paper carrier 6 by pressing down the roller carrier 4 while the ion fan 5 is running. The vacuum adsorption of the vacuum adsorption reflective paper carrier 6 is then turned off, allowing the reflective paper 7 to bond with the LED light panel 1. The adsorption using the vacuum adsorption holes on the carrier is then stopped, and the LED light panel 1, after the reflective paper bonding is completed, is placed on the conveyor belt 3.

[0132] In one embodiment of the present invention, the bonding device further includes an adjustment device.

[0133] The adjustment device is connected to the roller carrier 4. When the roller carrier 4 fails to identify the Mark point on the reflective paper 7, the adjustment device is used to adjust the position of the roller carrier 4 until the Mark point on the reflective paper 7 is identified.

[0134] It should be noted that the adjustment device can be a controller, or a combination of a controller and a displacement adjustment device. If it is a controller, the controller stores a pre-set program to control the operation of the bonding device.

[0135] In one embodiment of the present invention, the carrier is further provided with a separate cavity. By controlling the closing or opening of the separate cavity, the carrier corresponding to the separate cavity can stop adsorbing using the vacuum adsorption hole or perform adsorption using the vacuum adsorption hole when the vacuum adsorption state is activated.

[0136] In one embodiment of the present invention, the vehicle is further provided with reinforcing ribs 11; the reinforcing ribs 11 can enhance the strength of the vehicle and make the vehicle flat and non-deformable.

[0137] In one embodiment of the present invention, the number of carriers is 6, and the number of vacuum adsorption reflective paper carriers 6 is 6.

[0138] In this embodiment of the invention, the number of the carrier and the vacuum adsorption reflective paper carrier 6 can be adjusted as needed.

[0139] Taking the bonding of reflective paper to a Mini LED light panel as an example, such as Figure 2 As shown, the roller carrier 4 has 6 carriers, and 6 Mini LED light panels are adsorbed on the 6 carriers. The conveyor belt 3 has 6 vacuum adsorption reflective paper carriers 6.

[0140] The following explanation uses the batch lamination of reflective paper on a group of 6 Mini LED light panels as an example:

[0141] During the production of Mini LED light panels, reflective paper 7 (with the release film pre-removed) is fixed to a vacuum adsorption reflective paper carrier 6, and the vacuum adsorption reflective paper carrier 6 is placed on a conveyor belt 3. The vacuum adsorption reflective paper carrier 6 is then conveyed by the conveyor belt 3 to the area directly below the roller carrier 4.

[0142] Six Mini LED light panels are attached to the roller-type vehicle 4.

[0143] When ion fan 5 is running:

[0144] Once the roller carrier 4 identifies the Mark point on the reflective paper 7, it begins to press down and adhere it to the vacuum adsorption reflective paper carrier 6. After adhering to the vacuum adsorption reflective paper carrier 6, the adsorption of the vacuum adsorption reflective paper carrier 6 is turned off, so that the reflective paper 7 is adhered to the corresponding Mini LED light board. The individual cavity of the carrier corresponding to the Mini LED light board is closed, so that the Mini LED light board with the reflective paper adhered is placed on the conveyor belt 3.

[0145] When the roller carrier 4 fails to identify the Mark point of the reflective paper 7, the roller carrier 4 adjusts its position based on the set program until it identifies the Mark point of the reflective paper 7. It then begins to press down and adhere to the vacuum adsorption reflective paper carrier 6. After adhering to the vacuum adsorption reflective paper carrier 6, the adsorption of the vacuum adsorption reflective paper carrier 6 is turned off, so that the reflective paper 7 is adhered to the corresponding Mini LED light board. The individual cavity of the carrier corresponding to the Mini LED light board is closed, so that the Mini LED light board with the reflective paper adhered is placed on the conveyor belt 3.

[0146] The control roller carrier 4 rolls to the next vacuum adsorption reflective paper carrier 6 on the conveyor belt 3, and performs the Mark point recognition, pressing, bonding and closing adsorption operations again, and so on, until the bonding operation of a set of Mini LED light panels is completed.

[0147] A set of Mini LED light panels with reflective paper attached will be conveyed to the next process via conveyor belt 3.

[0148] In this embodiment of the invention, reflective paper lamination during LED light panel production effectively reduces operational difficulty. During lamination, the LED light panel and reflective paper are positioned on a conveyor belt and a roller carrier, respectively. The conveyor belt and roller carrier work together to determine the corresponding positions of the LED light panel and reflective paper when the roller carrier identifies the Mark point. Lamination is performed while the ion fan is running, controlling the roller carrier to achieve the lamination of the LED light panel and reflective paper. After lamination, the LED light panel with the reflected paper laminated is placed on the conveyor belt. The entire lamination process, conducted while the ion fan is running, prevents static electricity generation, ensuring high flatness of the laminated reflective paper, avoiding wrinkles during lamination, and improving lamination yield and efficiency. Furthermore, using a conveyor belt and roller carrier for reflective paper lamination enables mass production.

[0149] like Figure 4 The diagram shown is a flowchart illustrating another method for bonding reflective paper to an LED light panel according to an embodiment of the present invention. This method mainly includes the following steps:

[0150] S401: When producing LED light panels, vacuum adsorption is activated. The LED light panels are adsorbed onto the roller carrier with the back side facing out through the vacuum adsorption holes on the roller carrier, and the reflective paper is adsorbed onto the vacuum adsorption reflective paper carrier.

[0151] In S401, the dimensions of the vehicle are adapted to the dimensions of the LED light panel.

[0152] S402: The vacuum adsorption reflective paper carrier is conveyed to the area directly below the roller carrier via a conveyor belt.

[0153] S403: When the roller carrier identifies the Mark point on the reflective paper, execute S404.

[0154] S404: Perform bonding operation.

[0155] The bonding process includes:

[0156] When the ion fan is running, the roller carrier is pressed down to make the LED light panel on the carrier adhere to the vacuum adsorption reflective paper carrier. The vacuum adsorption of the vacuum adsorption reflective paper carrier is turned off, so that the reflective paper adheres to the LED light panel. The adsorption using the vacuum adsorption holes on the roller carrier is stopped, and the LED light panel with the reflective paper adhered is placed on the conveyor belt.

[0157] The ion fan is located on one side of the conveyor belt, with its outlet facing the roller carrier.

[0158] In one embodiment of the present invention, it further includes:

[0159] When the roller carrier fails to recognize the Mark point on the reflective paper, the roller carrier is controlled to adjust its position until the Mark point on the reflective paper is recognized, and then the bonding operation is performed.

[0160] In one embodiment of the present invention, multiple LED light panels are grouped together, and the number of roller carriers and the number of vacuum adsorption reflective paper carriers are the same as the number of LED light panels in a group. Each roller carrier is provided with a separate cavity.

[0161] In this embodiment of the invention, by controlling the closing or opening of individual cavities, the carrier corresponding to the individual cavity can stop adsorbing using the vacuum adsorption holes or perform adsorption using the vacuum adsorption holes when the vacuum adsorption state is activated.

[0162] When specifically implementing the bonding method disclosed in the embodiments of the present invention:

[0163] First, each LED panel is attached to one of the roller carriers with its back facing out through the vacuum suction holes on the roller carrier.

[0164] Secondly, the vacuum adsorption reflective paper carrier is conveyed to the area directly below the roller carrier via a conveyor belt.

[0165] Secondly, when the roller carrier identifies the Mark point on the reflective paper, while the ion fan is running, the roller carrier is controlled to press down, so that the LED light panel on the carrier is attached to the vacuum adsorption reflective paper carrier, and the vacuum adsorption of the vacuum adsorption reflective paper carrier is turned off, so that the reflective paper is attached to the LED light panel.

[0166] Secondly, close the individual cavity on the carrier corresponding to the LED light panel with the reflective paper, so that the LED light panel with the reflective paper attached is placed on the conveyor belt.

[0167] Finally, the roller carrier continues to roll until the reflective paper of a set of LED light panels is bonded. Then, the vacuum adsorption holes on the roller carrier are stopped, and the LED light panels with the reflective paper bonded are placed on the conveyor belt.

[0168] In one embodiment of the present invention, the LED light board is a Mini LED light board.
