Description

Technical Field

[0001] The present invention belongs to the technical field of display screens, and particularly relates to a display screen film laminating device. Background Art

[0002] In the production process of display screens, film lamination is a crucial process. By using a film laminating device for high-quality film lamination, not only can the screen be effectively protected from scratches and abrasions, but it can also, to a certain extent, resist scratches caused by sharp objects to the screen. However, despite the obvious importance of film lamination technology, there are many technical problems in the actual application of existing film laminating devices.

[0003] In the production process of modern display screens, in order to ensure a firm adhesion between the film and the display screen and prevent the film from falling off in the future, a certain temperature is usually applied to the film after film lamination. After retrieval, the LED display screen processing and production film laminating device with the patent application number CN202311518728.9 achieves the heating purpose by introducing a blowing structure. When heating is carried out by the blowing method, it may lead to uneven heat distribution, resulting in local overheating or insufficient heating of the film material; at the same time, since the film material is heated after preliminary fixing, displacement or deformation of the film material may occur during this period. Once the position of the film material changes, even a very small deviation may lead to a deterioration in the film lamination quality. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a display screen film laminating device to solve the problems existing in the above background art.

[0009] Preferably, the second height control scheme of the film taking head also includes a second lifting component, which is used to control the height of the film taking head so that the film taking head can perform film taking and film coating operations; the second lifting component is composed of a piston block and a piston cavity, the piston block is connected to the film taking head, and the lifting and lowering control of the film taking head is realized by changing the position of the piston block in the piston cavity; the piston block divides the piston cavity into a first cavity and a second cavity, and when the second lifting component controls the film taking head to descend, the volume of the first cavity becomes larger; the gas port of the piston cavity is located on the first cavity or on the side of the piston block facing the first cavity; an air inlet circuit and an air outlet circuit for controlling the size of the film coating cavity are respectively arranged between the piston cavity and the film coating cavity, the connection port of the air outlet circuit and the piston cavity is always located in the first cavity, the gas port is ventilated to the first cavity, the second lifting component controls the film taking head to descend, and when the connection port of the air inlet circuit and the piston cavity is located in the first cavity, the gas enters the film coating cavity through the air inlet circuit.

[0010] Further, a heating element is provided on the intake circuit, and the gas leading to the film covering cavity is heated by the heating element, so that while the film covering member completes the film covering operation, under the action of the hot gas in the film covering cavity, the film material and the screen are more closely attached.

[0011] Further, lifting blocks are provided on the connection ports of the intake circuit and the exhaust circuit. The lifting blocks are used to control the opening and closing of the intake circuit or the exhaust circuit, and a clamping block capable of contacting the piston block is provided on the lifting block; when the piston block moves, the lifting block is driven to move by the contact between the piston block and the clamping block, so as to realize the opening of the intake circuit or the exhaust circuit.

[0012] In order to solve the above technical problems, the second technical solution of the present invention is a method for using the display screen film covering device when the height control solution of the film taking head in the first technical solution is the second solution. The using method includes the following steps:

[0013] S1. Film taking: Use the linear moving member to move the film taking head to the material taking position; adjust the height of the first lifting member so that the film taking head approaches the film material; when the film taking head approaches the film material, simultaneously reduce the air pressure inside the film taking cavity and the film covering cavity, and under the action of the diaphragm, while ensuring that the position of the film covering member remains unchanged, the film taking cavity sucks the film material through the air holes; adjust the first lifting member to raise the film taking head.

[0014] S2. Moving: Use the linear moving member to move the film taking head from the material taking position to the film covering position.

[0015] S3.

[0016] S3. Resetting: After completing the film covering, adjust the first lifting member to raise the film taking head and prepare for the next operation.

[0017] In order to solve the above technical problems, the technical solution of the present invention is a method for using the display screen film covering device when the height control solution of the film taking head in the first technical solution is the second solution. The using method includes the following steps:

[0018] S1. Film picking: Use the linear moving component to move the film picking head to the material picking position; ventilate the first cavity through the gas port to prompt the piston block to move within the piston cavity, causing the film picking head to descend and approach the film material; at this time, since the piston block does not contact the clamping block, both the intake circuit and the exhaust circuit remain closed; when the film picking head approaches the film material, simultaneously reduce the air pressure inside the film picking cavity and the film laminating cavity. Under the action of the diaphragm, while ensuring that the film laminating component remains in place, the film picking cavity sucks the film material through the air holes; perform a pumping operation on the first cavity through the gas port, so that the piston block drives the film picking head to rise;

[0019] S2. Movement: Use the linear moving component to move the film picking head from the material picking position to the film laminating position;

[0020] S3. Film laminating: Start the heating element in the intake circuit to heat the gas about to enter the film laminating cavity; ventilate the first cavity through the gas port to prompt the piston block to move within the piston cavity, aligning the film material accurately with the screen to be film laminated; continuously ventilate the first cavity through the gas port. When the connection ports of the intake circuit and the exhaust circuit are located in the first cavity, the heated gas enters the film laminating cavity through the intake circuit, increasing the air pressure inside the film laminating cavity and prompting the film laminating component to move towards the film picking cavity direction, completing the film laminating operation of the film material on the screen;

[0021] S3. Reset: After completing the film lamination, perform a pumping operation on the first cavity through the gas port, so that the piston block drives the film picking head to rise, preparing for the next round of operation.

[0022] The technical effects of the present invention are mainly reflected in the following aspects:

[0023] By means of heat control when introducing gas into the film laminating cavity, while increasing the air pressure inside the film laminating cavity, it can also provide the necessary heat to help the film material better adhere to the screen surface. This design solves the problems of local overheating or uneven temperature distribution caused by traditional heating methods, ensuring the film laminating quality. Its advantage lies in providing a uniform and controllable heating effect, enhancing the adhesion between the film material and the screen, and at the same time avoiding the risk of the film material deforming due to excessive heating.

[0024] The second lifting component composed of a piston block and a piston chamber is adopted to control the height of the film taking head. The piston block divides the piston chamber into a first chamber and a second chamber, and the film taking head is lifted or lowered by ventilating or pumping air into the first chamber through a gas port. The film taking head is allowed to perform independent lifting and lowering operations without opening the air inlet circuit and the air outlet circuit, so as to adapt to different height requirements. Such a design also enables the lifting action of the film taking head to be synchronized with the air pressure regulation in the film covering chamber. During the film covering stage, the movement of the piston block not only drives the film taking head to descend, but also triggers the opening of the air inlet circuit, enabling the heated gas to enter the film covering chamber to complete the film covering operation. This synchronous control mechanism greatly improves the production efficiency and reduces the time required for separate operations. Its advantages lie in simplifying the operation process, reducing the waiting time between steps, and ensuring high precision and high quality during the film covering process.

Additionally, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be bolt fixing, pin fixing, or pin shaft connection, etc., which are commonly used in the prior art. Therefore, it will not be elaborated in this embodiment.

[0033] Embodiment 1

[0034] Refer to Figure 2 、 Figure 3 As shown in

[0035] Refer to Figure 2, on one side of the film taking head 1, there is a film taking plate 15 for opening the air holes 12, and the film taking plate 15 is made of flexible material; on one side of the film covering member 2 located in the film covering cavity 14, there is a diaphragm 21, and the diaphragm 21 acts on the film taking plate 15 on one side of the film covering cavity 14; under the action of the diaphragm 21, the film covering cavity 14 is in a sealed state at any position in the air chamber 11, thus ensuring the effectiveness of air pressure regulation; by controlling the size of the film taking plate 15 on one side of the film taking cavity 13, the suction of different specifications of film materials can be realized; even by changing the number and distribution of the air holes 12 on the film taking plate 15, different sizes and shapes of film materials can be adapted, so as to adjust the adaptability to different specifications of film materials according to actual needs, and the application scenarios of the equipment are increased.

[0036] See Figure 6 , it further includes a material taking position 3 and a film covering position 4. The material taking position 3 is used for placing film materials, and the film covering position 4 is used for placing the screen; a linear moving component 5, and the linear moving component 5 is used to control the movement of the film taking head 1 between the material taking position 3 and the film covering position 4; on the material taking position 3 and the film covering position 4, there are respectively a screen loading belt 42 and a film material loading belt 31; by combining the automatic supply system (loading belt) of film materials and the screen with the film taking head 1 and the linear moving component 5, a highly automated process from film material selection to film covering completion is realized. By simply replacing the film taking plate 15, different specifications and shapes of film materials can be easily adapted, greatly enhancing the versatility and flexibility of the equipment; and a pressure sensor is installed in the film taking cavity 13 to monitor the air pressure change situation, so as to feedback the state of material taking (such as whether the film material is successfully adsorbed).

[0037] It further includes a first lifting component, and the first lifting component is used to control the height of the film taking head 1, so as to facilitate the film taking and film covering operations of the film taking head 1; enabling the equipment to adapt to different thickness combinations of the screen and the film material and improving the operation flexibility. A hot air component, and the output end of the hot air component is connected to the film covering cavity 14; by the way of conveying heated gas into the film covering cavity 14, while completing the film covering, the film material and the screen are made to fit more closely by the hot gas, avoiding the problem of local overheating. During film covering, by the way of conveying heated gas into the film covering cavity 14 through the hot air component, the internal air pressure of the film covering cavity 14 is increased, so that while the film covering member 2 completes the film covering operation, under the action of the hot gas in the film covering cavity 14, the film material and the screen are made to fit more closely. Using the hot air component to provide heated gas acting on the film material and the screen through the film covering cavity 14 ensures uniform heat distribution and effectively solves the problem of local overheating.

[0038] Embodiment 2

[0039] This embodiment discloses a display screen laminating device. Compared with the first embodiment, this embodiment provides a replacement solution for the first lifting component and the hot air component, which is specifically as follows:

[0040] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , the display screen laminating device further includes a second lifting component 6, and the second lifting component 6 is used to control the height of the film taking head 1 so as to facilitate the film taking and laminating operations of the film taking head 1; the second lifting component 6 is composed of a piston block 61 and a piston chamber 62, the piston block 61 is connected to the film taking head 1, and the lifting control of the film taking head 1 is realized by the position change of the piston block 61 in the piston chamber 62; the piston block 61 divides the piston chamber 62 into a first chamber 63 and a second chamber 64. When the second lifting component 6 controls the film taking head 1 to descend, the volume of the first chamber 63 becomes larger; the gas port of the piston chamber 62 is located on the first chamber 63 or on the side of the piston block 61 facing the first chamber 63; an air inlet circuit 65 and an air outlet circuit 66 for controlling the size of the laminating chamber 14 are respectively arranged between the piston chamber 62 and the laminating chamber 14, the connection port of the air outlet circuit 66 and the piston chamber 62 is always located in the first chamber 63, the gas port ventilates the first chamber 63, and the second lifting component 6 controls the film taking head 1 to descend. When the connection port of the air inlet circuit 65 and the piston chamber 62 is located in the first chamber 63, gas enters the laminating chamber 14 through the air inlet circuit 65.

[0041] A heating element is provided on the air inlet circuit 65, and the gas leading to the laminating chamber 14 is heated by the heating element, so that while the laminating part 2 completes the laminating operation, under the action of the hot air in the laminating chamber 14, the film material and the screen are more closely attached; heating the gas by the heating element on the air inlet circuit 65 ensures uniform distribution of heat, improves the adhesion between the film material and the screen, and at the same time avoids the problem of local overheating.

[0042] See Figure 5, lifting blocks 67 are provided on the connection ports of the intake circuit 65 and the outlet circuit 66. The lifting blocks 67 are used to control the opening and closing of the intake circuit 65 or the outlet circuit 66. A clamping block 68 that can contact the piston block 61 is provided on the lifting block 67; when the piston block 61 moves, the lifting block 67 is driven to move by the contact between the piston block 61 and the clamping block 68, so as to realize the opening of the intake circuit 65 or the outlet circuit 66; through the design of the piston block 61 and the clamping block 68, the opening and closing of the intake circuit 65 and the outlet circuit 66 are automatically controlled, reducing the need for manual intervention and improving the automation degree and reliability of the system. The lifting block 67 is normally closed under the control of a spring. When only the film taking head 1 is lifted or lowered, the piston block 61 can move freely between the two clamping blocks 68.

[0043] In this embodiment, the synchronous control of the lifting of the film taking head 1 and the film covering operation is realized. At the same time, when taking materials, the lifting of the film taking head 1 can be carried out independently. The principle lies in the linkage design of the piston chamber 62 with the intake circuit 65 and the outlet circuit 66. Specifically, when the film taking head 1 only performs the lifting operation (such as the material taking stage), since the piston block 61 does not contact the clamping block 68, the intake circuit 65 and the outlet circuit 66 remain closed, and the gas only acts on the first chamber 63 to drive the piston block 61 to move, so as to realize the independent lifting of the film taking head 1; while in the film covering stage, the lifting block 67 is driven to move by the contact between the piston block 61 and the clamping block 68, automatically opening the intake circuit 65 and the outlet circuit 66, so that the heating gas enters the film covering chamber 14 to complete the air pressure adjustment and the film covering operation. The advantages of this design are as follows: on the one hand, the control logic is simplified through mechanical linkage, avoiding a complex external control system and improving the reliability and compactness of the equipment; on the other hand, the decoupling operation of the lifting of the film taking head 1 and the film covering operation is realized, which not only ensures the flexibility during material taking, but also can achieve efficient synchronous control during film covering, significantly improving the production efficiency and the film covering quality.

[0044] Embodiment Three

[0045] This embodiment discloses a method for using the display screen film covering device as described in Embodiment One. The method includes the following steps:

[0046] S1. Film taking: Use the linear moving component 5 to move the film taking head 1 to the material taking position 3; adjust the height of the first lifting component so that the film taking head 1 approaches the film material placed on the film material loading belt 31; when the film taking head 1 approaches the film material, simultaneously reduce the air pressure inside the film taking chamber 13 and the film covering chamber 14. Due to the effect of the diaphragm 21, while ensuring that the position of the film covering part 2 remains unchanged under the action of the diaphragm 21, the film taking chamber 13 sucks the film material through the air holes 12; after successfully adsorbing the film material, adjust the first lifting component to raise the film taking head 1 to prepare to transfer the film material to the film covering position 4;

[0047] S2. Movement: Use the linear movement component 5 to move the film taking head 1 from the film taking position 3 to the film laminating position 4;

[0048] S3. Film Laminating: After reaching the film laminating position 4, adjust the height of the first lifting component to accurately align the film material with the screen to be laminated; Deliver heated gas into the film laminating cavity 14 through the hot air component to increase the air pressure in the film laminating cavity 14. This not only increases the air pressure in the film laminating cavity 14 but also provides the necessary heat to help the film material better adhere to the screen surface. As the air pressure in the film laminating cavity 14 increases, the film laminating component 2 is pushed to move towards the film taking cavity 13 direction to complete the film laminating operation of the film material on the screen.

[0049] S3. Reset: After completing the film laminating, adjust the first lifting component to raise the film taking head 1, remove the laminated screen, and prepare for the next round of film taking and film laminating cycle.

[0050] Embodiment 4

[0051] This embodiment discloses a usage method of a display screen film laminating device as described in Embodiment 2. The usage method includes the following steps:

[0052] S1. Film Taking: Use the linear movement component 5 to move the film taking head 1 to the film taking position 3; Ventilate the first cavity 63 through the gas port to prompt the piston block 61 to move within the piston cavity 62, causing the film taking head 1 to descend and approach the film material; At this time, since the piston block 61 does not contact the latch 68, both the intake air circuit 65 and the exhaust air circuit 66 remain in a closed state; When the film taking head 1 approaches the film material, simultaneously reduce the air pressure inside the film taking cavity 13 and the film laminating cavity 14. While ensuring the position of the film laminating component 2 remains unchanged under the action of the diaphragm 21, the film taking cavity 13 sucks the film material through the air holes 12; After successfully adsorbing the film material, perform a gas extraction operation on the first cavity 63 through the gas port, so that the piston block 61 drives the film taking head 1 to rise;

[0053] S2. Movement: Use the linear movement component 5 to move the film taking head 1 from the film taking position 3 to the film laminating position 4;

[0054] S3. Film Laminating: Activate the heating element in the intake circuit 65 to heat the gas about to enter the film laminating chamber 14, preparing for the subsequent film laminating operation; ventilate the first cavity 63 through the gas port to prompt the piston block 61 to move within the piston chamber 62, aligning the film material accurately with the screen to be laminated; continuously ventilate the first cavity 63 through the gas port. When the connection ports of the intake circuit 65 and the exhaust circuit 66 are located in the first cavity 63, the heated gas enters the film laminating chamber 14 through the intake circuit 65, increasing the air pressure in the film laminating chamber 14. As the air pressure in the film laminating chamber 14 increases, the laminating part 2 is pushed towards the film taking chamber 13, completing the film laminating operation on the screen. Heating the gas helps improve the adhesion between the film material and the screen, ensuring a closer fit between the two.

[0055] S3. Reset: After film laminating is completed, perform a pumping operation on the first cavity 63 through the gas port, so that the piston block 61 drives the film taking head 1 to rise, remove the laminated screen, and prepare for the next cycle of film taking and film laminating.

[0056] In addition, as common knowledge in this industry, the first lifting component and the linear moving component 5 mentioned above can specifically be telescopic cylinders, telescopic rods, and sliding tables; a negative pressure generator is used to reduce air pressure, an air pump is used to increase air pressure, as well as hot air components, heating elements, the screen loading belt 42, and the film material loading belt 31. The above is common knowledge; therefore, the principles and structures thereof will not be elaborated in detail.

Film coating: Adjust the height of the first lifting member to accurately align the film material with the screen to be film coated; Send heated gas into the film coating cavity through the hot air member, increase the air pressure in the film coating cavity, and prompt the film coating member to move towards the film taking cavity to complete the film coating operation of the film material on the screen; S3. Reset: After the film coating is completed, adjust the first lifting member to raise the film taking head to prepare for the next operation.

9. A method for using a display screen film laminating device as described in claim 7, characterized in that: The usage method includes the following steps: S1. Film taking: Use the linear moving member to move the film taking head to the material taking position; Ventilate the first cavity through the gas port to prompt the piston block to move in the piston cavity, so that the film taking head descends and approaches the film material; at this time, since the piston block does not contact the clamping block, both the intake air circuit and the exhaust air circuit remain in a closed state; After the film taking head approaches the film material, simultaneously reduce the air pressure inside the film taking cavity and the film coating cavity. While ensuring the position of the film coating member remains unchanged under the action of the diaphragm, the film taking cavity sucks the film material through the air holes; Perform an air extraction operation on the first cavity through the gas port, so that the piston block drives the film taking head to rise; S2. Moving: Use the linear moving member to move the film taking head from the material taking position to the film coating position; S3. Film coating: Start the heating element in the intake air circuit to heat the gas about to enter the film coating cavity; Ventilate the first cavity through the gas port to prompt the piston block to move in the piston cavity to accurately align the film material with the screen to be film coated; Continuously ventilate the first cavity through the gas port. When the connection ports of the intake air circuit and the exhaust air circuit are located in the first cavity, the heated gas enters the film coating cavity through the intake air circuit, increasing the air pressure in the film coating cavity and prompting the film coating member to move towards the film taking cavity, completing the film coating operation of the film material on the screen; S3. Reset: After the film coating is completed, perform a pumping operation on the first cavity through the gas port, so that the piston block drives the film taking head to rise, preparing for the next round of operation.
