Description

Technical Field

[0001] This utility model relates to the technical field of hot pressing devices, and in particular to a hot pressing device for the production of LCD screens. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of flat-panel display technology widely used in electronic devices such as televisions, computer monitors, and smartphones. Their main characteristics include low power consumption, small size, light weight, and low radiation. In the manufacturing process of LCDs, hot-pressing technology is a key process, primarily used to ensure the structural integrity and performance of the LCD display.

[0003] In the existing technology, during the hot pressing process, two glass plates need to be placed in the assembly machine. At this time, the alignment and positioning of the two glass plates are very important. During the alignment process, the positioning fixture that abuts against the edge of the LCD screen will affect the operation of the hot pressing assembly. However, making the hot pressing assembly smaller will affect the coverage of the LCD screen and affect the hot pressing production of the LCD screen. Utility Model Content

[0004] This application provides a hot pressing device for LCD screen production, which can ensure the clamping effect of the LCD screen while preventing the clamp from interfering with the hot pressing module during the LCD screen hot pressing operation. It can ensure the hot pressing accuracy while the LCD screen is hot pressed normally, thereby effectively improving the practicality of the hot pressing device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A hot pressing apparatus for LCD screen production includes:

[0007] The base has a flat surface on top for placing the LCD screen, and the top of the base is connected to a top plate via a support column;

[0008] The hot-pressing module, located at the top of the base, is used for hot-pressing the LCD screen. The hot-pressing module is connected to the bottom of the top plate via a lifting unit.

[0009] The clamping assembly, located on the top of the base, is used for aligning the LCD screen. The clamping assembly includes a slide, a pressure plate, and a conveyor belt. There are four slides, which are respectively located on the four sides of the top of the base. A notch is opened on the side of the slide closest to the hot pressing module. The pressure plate is connected to the notch through an elastic element. A mounting groove is opened on the top of the pressure plate on the side closest to the hot pressing module. The conveyor belt for squeezing the LCD screen is connected to the mounting groove.

[0010] Furthermore, the top of the base is provided with a sliding groove, and the slide is slidably disposed in the sliding groove, with the top of the slide flush with the top of the base.

[0011] Furthermore, the height of the notch is the same as the height of the pressure plate, so that when the pressure plate is fully pressed into the notch, the top of the pressure plate is flush with the top of the base.

[0012] Furthermore, a rotating shaft for supporting the conveyor belt is rotatably connected within the mounting groove, and one end of the rotating shaft is connected to the side wall of the mounting groove via a one-way bearing.

[0013] Furthermore, the side surface of the conveyor belt near the hot pressing module extends out of the mounting groove, and a support plate for supporting the conveyor belt is fixedly connected inside the mounting groove on the side near the hot pressing module.

[0014] Furthermore, the elastic element includes a sleeve and a spring. The bottom of the pressure plate is provided with a circular groove for accommodating the sleeve. The sleeve is slidably connected in the circular groove. The bottom of the sleeve is fixedly connected to the bottom wall of the mounting groove. A spring for supporting the pressure plate is placed inside the sleeve.

[0015] Furthermore, the lifting unit includes a hydraulic press and a guide rod, both of which are located on the top of the top plate. The hydraulic press is fixedly connected to the top plate, the output shaft of the hydraulic press passes through the top plate and is fixedly connected to the hot pressing module, the guide rod is slidably connected to the top plate, and the bottom of the guide rod passes through the top plate and is fixedly connected to the hot pressing module.

[0016] In summary, this utility model has at least one of the following beneficial technical effects:

[0017] 1. A hot pressing device for LCD screen production, through a clamping component, allows the edge of the hot pressing module to press the pressure plate when the hot pressing module descends, causing the pressure plate to move downward within the notch. As the pressure plate moves downward, the conveyor belt in contact with the LCD screen moves, thus maintaining the pressing state of the LCD screen while allowing the pressure plate to move downward normally. This also prevents the parts in contact with the LCD screen from sliding and causing damage to the LCD screen. It ensures that the hot pressing module presses the LCD screen tightly while avoiding damage to the LCD screen by the clamping component, thereby further improving the quality of the LCD screen.

[0018] 2. This hot pressing device for LCD screen production, through the setting of a rotating shaft and a one-way bearing, allows the spring element to push the pressure plate upward after the LCD screen is hot pressed and the hot pressing module is reset, so that the conveyor belt re-contacts the LCD screen. At this time, the conveyor belt cannot move due to the interference of the one-way bearing, and the upward movement of the pressure plate will lift the LCD screen, making it easier to unload the LCD screen and further improving the hot pressing production efficiency of the LCD screen.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example: Refer to Figures 1-6 The present invention discloses a hot pressing device for LCD screen production, comprising:

[0029] The base 1 has a flat surface on its top for placing the LCD screen, and the top of the base 1 is connected to the top plate 5 via a support column 4.

[0030] The hot-pressing module 2 is located on the top of the base 1 and is used for hot-pressing the LCD screen. The hot-pressing module 2 is connected to the bottom of the top plate 5 through the lifting unit 6.

[0031] The clamping assembly 3 is located on the top of the base 1 and is used for aligning the LCD screen. The clamping assembly 3 includes a slide table 31, a pressure plate 32, and a conveyor belt 33. There are four slide tables 31, which are respectively located on the four sides of the top of the base 1. A notch 7 is provided on the side of the slide table 31 near the hot pressing module 2. The pressure plate 32 is connected to the notch 7 through a spring member 8. An installation groove 9 is provided on the top of the pressure plate 32 near the hot pressing module 2. The conveyor belt 33 for squeezing the LCD screen is connected to the installation groove 9.

[0032] In this embodiment, observation Figure 1 and Figure 2 It can be seen that by setting a base 1, the top of the base 1 is machined with a flat surface for placing the LCD screen, and then support columns 4 are connected to the four corners of the top of the base 1. The top plate 5 is fixedly connected to the top of the support columns 4. The top plate 5 is connected to the hot pressing module 2 through the lifting unit 6. When hot pressing the LCD screen, the lifting unit 6 can be used to control the hot pressing module 2 to move down, thereby performing hot pressing operation on the LCD screen placed on the top of the base 1.

[0033] During the hot pressing process, two glass plates need to be placed in the assembly machine. At this time, the alignment and positioning of the two glass plates are very important. During the alignment process, the positioning fixture that abuts against the edge of the LCD screen will affect the operation of the hot pressing assembly. However, making the hot pressing assembly smaller will affect the coverage of the LCD screen and affect the hot pressing production of the LCD screen.

[0034] Therefore, further observation is needed. Figure 2 It can be seen that four sets of clamping components 3 are provided on the top of the base 1. The four sets of clamping components 3 are respectively located on the four sides of the top of the base 1, so that the four clamping components 3 can clamp the LCD screen when they are closed.

[0035] Then looked at Figure 3 It can be seen that the clamping assembly 3 includes a slide table 31, a pressure plate 32, and a conveyor belt 33. There are four slide tables 31, which are respectively set on the four sides of the top of the base 1. A notch 7 is opened on the side of the slide table 31 near the hot pressing module 2. The pressure plate 32 is connected to the notch 7 through the elastic member 8. The top of the pressure plate 32 is opened on the side near the hot pressing module 2. The conveyor belt 33 for squeezing the LCD screen is connected in the mounting groove 9.

[0036] At this time, when the slide table 31 slides and the pressure plate 32 comes into contact with the LCD screen, the conveyor belt 33 will come into contact with the LCD screen. Then, under the pressure of the taut conveyor belt 33, the edges of the upper and lower LCD screens can be made flush. At the same time, the flexible conveyor belt 33 will also provide a small amount of buffer when squeezing the LCD screen, which can protect the LCD screen and prevent it from being damaged.

[0037] Finally, after the LCD screen is aligned, the lifting unit 6 can be activated by the controller to lower the hot pressing module 2 to perform hot pressing on the LCD screen. As the hot pressing module 2 descends, its edge will press the pressure plate 32, causing the pressure plate 32 to move downward within the notch 7. When the pressure plate 32 moves downward, the conveyor belt 33 in contact with the LCD screen will move, thus maintaining the state of pressing the LCD screen while allowing the pressure plate 32 to move downward normally. This also prevents the parts in contact with the LCD screen from sliding and causing damage to the LCD screen. This ensures that the hot pressing module 2 presses the LCD screen tightly while avoiding damage to the LCD screen caused by the clamping component 3, which can further improve the quality of the LCD screen.

[0038] Finally, after the LCD screen hot pressing is completed, the lifting unit 6 lifts the hot pressing module 2, and then the pressure plate 32, which is no longer compressed, will be reset by the push of the elastic member 8, so as to clamp the LCD screen and align it before the next LCD screen hot pressing process, thereby effectively improving the production efficiency of LCD screen hot pressing.

[0039] In a further preferred embodiment of this utility model, such as Figure 2 As shown, by providing a groove 10 on the top of the base 1, the slide table 31 is slidably disposed in the groove 10. The top of the slide table 31 is flush with the top of the base 1, so that the hot pressing module 2 will not come into contact with the slide table 31 after being fully pressed down, thereby ensuring that the hot pressing module 2 can fit with the LCD screen and ensuring the hot pressing effect.

[0040] In order to ensure that the slide table 31 slides normally in the slide groove 10, a motor can be used to drive the lead screw to rotate so that the slide table 31 moves linearly. Since this technology is very mature, it will not be elaborated on further.

[0041] In a further preferred embodiment of this utility model, such as Figure 5 As shown, by making the height of the notch 7 the same as the height of the pressure plate 32, when the pressure plate 32 is fully pressed into the notch 7, the top of the pressure plate 32 is flush with the top of the base 1. This can prevent the pressure plate 32 from touching the hot pressing module 2, which would prevent it from completely pressing the LCD screen, thereby further ensuring the hot pressing effect of the LCD screen.

[0042] In a further preferred embodiment of this utility model, such as Figure 6 As shown, a rotating shaft 11 for supporting the conveyor belt 33 is rotatably connected in the mounting groove 9. One end of the rotating shaft 11 is connected to the side wall of the mounting groove 9 through a one-way bearing 12. This allows the conveyor belt 33 to move normally when the pressure plate 32 is squeezed down, so that the contact area between the conveyor belt 33 and the LCD screen is in a relatively static state. This ensures the clamping and positioning effect of the LCD screen while allowing the pressure plate 32 to move down normally.

[0043] After the LCD screen is hot-pressed, as the hot-pressing module 2 is reset, the elastic element 8 will push the pressure plate 32 upward, so that the conveyor belt 33 will re-contact the LCD screen. At this time, the conveyor belt 33 cannot move due to the interference of the one-way bearing 12. The upward movement of the pressure plate 32 will lift the LCD screen, making it easier to unload the LCD screen and further improving the hot-pressing production efficiency of the LCD screen.

[0044] In order to ensure the frictional force between the conveyor belt 33 and the rotating shaft 11, Figure 6 It can also be seen that a tensioning component for tensioning the conveyor belt 33 is provided in the mounting groove 9 to ensure that the conveyor belt 33 is in a taut state. The tensioning component uses a cylinder or spring to push a rotating roller to abut against the conveyor belt 33 to achieve the tensioning effect. This is a structure commonly used by those in the art, so it will not be described in detail.

[0045] In a further preferred embodiment of this utility model, such as Figure 6 As shown, by extending the mounting groove 9 from the side surface of the conveyor belt 33 that is close to the hot pressing module 2, the conveyor belt 33 can contact the LCD screen when the pressure plate 32 is close to the LCD screen, thus preventing the hard pressure plate 32 from damaging the LCD screen.

[0046] By fixing a support plate 13 for supporting the conveyor belt 33 to one side of the mounting groove 9 near the hot pressing module 2, the support plate 13 can provide support for the conveyor belt 33, ensuring the squeezing effect of the conveyor belt 33 on the LCD screen and avoiding elastic deformation of the conveyor belt 33 that would affect the alignment accuracy of the LCD screen.

[0047] Finally, in order to improve the service life of the conveyor belt 33, the sidewall of the support plate 13 is smoothed to reduce frictional damage when the conveyor belt 33 moves.

[0048] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the elastic component 8 includes a sleeve 81 and a spring 82. The bottom of the pressure plate 32 is provided with a circular groove 14 for accommodating the sleeve 81. The sleeve 81 is slidably connected in the circular groove 14. The bottom of the sleeve 81 is fixedly connected to the bottom wall of the mounting groove 9. The spring 82 for supporting the pressure plate 32 is placed in the sleeve 81. When the pressure plate 32 moves down, the sleeve 81 can be used to assist in the movement, making the downward movement of the pressure plate 32 more stable. After the pressure plate 32 is no longer compressed, the spring 82 can push the pressure plate 32 to reset, making the operation of the clamping assembly 3 more stable.

[0049] In a further preferred embodiment of this utility model, such as Figure 2As shown, the lifting unit 6 includes a hydraulic press 61 and a guide rod 62. Both the hydraulic press 61 and the guide rod 62 are located on the top of the top plate 5. The hydraulic press 61 is fixedly connected to the top plate 5. The output shaft of the hydraulic press 61 passes through the top plate 5 and is fixedly connected to the hot pressing module 2. When the hydraulic press 61 is running, it can push the hot pressing module 2 down to press the LCD screen for hot pressing.

[0050] The guide rod 62 is slidably connected to the top plate 5. The bottom of the guide rod 62 passes through the top plate 5 and is fixedly connected to the hot pressing module 2. This can assist the movement of the hot pressing module 2 when it moves down, making the downward movement of the hot pressing module 2 more stable and the pressure of the hot pressing module 2 on the LCD screen more even, thereby avoiding local damage to the LCD screen.

[0051] The implementation principle of the above embodiment is as follows: First, the LCD screen is placed on the top of the base 1. Then, the controller is used to start the motors of the four clamping components 3 at the same time, so that the four clamping components 3 approach and clamp the LCD screen. Then, the hydraulic press 61 can be started to lower the hot press module 2.

[0052] When the hot pressing module 2 moves downward, it will squeeze the pressure plate 32, thereby causing the pressure plate 32 to move downward. This can prevent the hot pressing module 2 from being affected by the pressure plate 32 when hot pressing the LCD screen, thus effectively ensuring the hot pressing quality of the LCD screen.

[0053] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
