Abstract
Description
Technical Field
[0001] This application relates to the field of liquid crystal module technology, and in particular to a high load-bearing capacity light source positioning structure and a liquid crystal module. Background Technology
[0002] Liquid crystal display (LCD) modules utilize a liquid crystal solution within two polarizing materials. When an electric current passes through the liquid, the crystals rearrange to achieve image formation. The current also causes the crystals to rearrange, blocking light from passing through. Thus, each crystal acts like a Venetian blind, allowing light to pass through while simultaneously blocking it. LCD modules have evolved towards being lighter, thinner, shorter, and smaller, and monitors, with their long history in computer peripherals, are no exception. Traditional display methods, such as CRT monitors and LED displays, are limited by their large size and high power consumption, failing to meet users' practical needs. The development of LCD technology perfectly aligns with current trends in information products, offering advantages such as right-angle display, low power consumption, small size, and zero radiation, providing users with an optimal visual environment.
[0003] The LCD panel and backlight assembly are crucial components of an LCD module. The LCD panel is positioned above the light-emitting surface of the backlight assembly and is typically supported by a frame. A certain distance must be maintained between the LCD panel and the backlight assembly to ensure uniform light transmission. Accurate positioning between the backlight assembly and the LCD panel is essential to ensure uniform light transmission and prevent uneven brightness or dark areas. This is critical for improving display quality, as uneven light can cause mottled or blurry images. Furthermore, accurate positioning contributes to better contrast and color reproduction, and proper installation reduces friction and stress between the LCD panel and the backlight module, thus extending the overall lifespan of the LCD module.
[0004] However, in the assembly process of existing LCD modules, it is difficult to ensure the accuracy of the relative position between the LCD panel and the backlight assembly. The difficulty in accurately loading the backlight assembly during the feeding process is one of the reasons for the large deviation in the relative position between the LCD panel and the backlight assembly. Summary of the Invention
[0005] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a high load-bearing capacity light source positioning structure, which can at least achieve accurate positioning of backlight components and has high load-bearing capacity, enabling the positioning of backlight components in batches.
[0006] A high-load-bearing capacity light source positioning structure according to a first aspect embodiment of this application includes:
[0007] The support layer has multiple sets arranged in a vertical direction. Each set of the support layer has several light source support positions, which are used to support the liquid crystal backlight assembly.
[0008] A pressure plate is connected to the driving end of a first driving member. The first driving member is used to drive the pressure plate to press down the uppermost bearing layer and to make each bearing layer press down the bearing layer below it.
[0009] In addition to the bottommost load-bearing plate, each set of load-bearing plates is connected to at least one counterweight. The counterweight is used to apply an upward pulling force to the load-bearing plate so that each load-bearing plate applies the same pressure to the load-bearing plate below it.
[0010] A positioning and correction component is disposed on the support layer plate. During the pressing of the pressure plate or the support layer plate, the positioning and correction component is driven synchronously to push the liquid crystal backlight component to move to a preset position.
[0011] The high load-bearing capacity light source positioning structure of the present application embodiment can produce the following technical effects:
[0012] The first driving component drives the pressure plate to press down on the uppermost support layer, which in turn presses down on the support layer below it, and then on the support layer below that. During the pressing process, the pressure plate or support layer simultaneously drives the positioning and correction components to move the LCD backlight assembly to a preset position, thereby achieving precise positioning and correction of the LCD backlight assembly. Furthermore, by connecting at least one counterweight to each support layer (except the lowermost one), an upward pulling force is applied to the support layer, ensuring that each support layer exerts the same pressure on the support layer below it. This design avoids the weight of the support layer itself affecting the downward pressure, preventing the positioning and correction components on the lower support layer from experiencing greater pressure than those on the upper support layer. Therefore, the high-load-bearing light source positioning structure possesses high load-bearing capacity, enabling simultaneous positioning of the light source assemblies on multiple light source support positions across multiple support layers.
[0013] Specifically, the first driving member in this embodiment can be a linear driving member that directly drives the pressure plate to move downward, or it can be a rotary driving member. When the first driving member is a rotary driving member, the driving end of the first driving member is connected to a first gear, the guide rod that passes through each bearing plate is a screw, the screw is sleeved with a second gear, and the first gear and the second gear are connected by a transmission belt or by gear meshing.
[0014] Understandably, the guide rod is connected to the bottommost load-bearing plate and the topmost fixing seat at both ends. The fixing seat is used to fix the first driving component, and the driving end of the first driving component passes through the fixing seat.
[0015] Preferably, a chain is provided between the pressure plate and the bearing layer, and between adjacent bearing layers. In the initial state, the chain is straight. After the positioning work is completed, when the pressure plate rises and resets, the chain can drive each bearing layer to reset to its initial position.
[0016] According to one embodiment provided in this application, the positioning and correction component is configured to correspond one-to-one with the light source carrier position. The positioning and correction component includes a first clamping member and a second clamping member that slide with the carrier plate. The first clamping member and the second clamping member form a corresponding light source carrier position for placing the liquid crystal backlight assembly.
[0017] During the process of the bearing plate on which the positioning and correction components are provided being pressed down by the bearing plate above it, the pressure plate or the bearing plate above the group of positioning and correction components synchronously drives the group of positioning and correction components to push the first clamping member and the second clamping member in the group of positioning and correction components closer to each other, so that the liquid crystal backlight component located between the first clamping member and the second clamping member tends to a preset position.
[0018] According to one embodiment provided in this application, it also includes
[0019] A pressing component is provided in a one-to-one correspondence with the positioning and correction component, and is located on the lower surface of the pressure plate or the support layer above the corresponding positioning and correction component. The pressing component includes a first pressing member and a second pressing member. When the pressure plate or the support layer presses down on the support layer below it, the first pressing member and the second pressing member press down on the first clamping member and the second clamping member respectively, so that the first clamping member and the second clamping member move closer to each other, and the liquid crystal backlight component located between the first clamping member and the second clamping member tends to a preset position.
[0020] According to one embodiment provided in this application, a first pressure roller is rolledly connected to the bottom of the first pressing member, and the first pressure roller is rolledly engaged with the top surface of the first clamping member located below it.
[0021] The bottom of the second pressing member is rolledly connected to a second pressure roller, which rolls into contact with the top surface of the second clamping member located below it.
[0022] It is understandable that by using a rolling contact method, the friction between the pressing component and the clamping component during the downward correction process is reduced, thereby improving the structural life and making the movement more stable and controllable.
[0023] According to one embodiment provided in this application, the top surfaces of the first clamping member and the second clamping member are inclined surfaces that are closer to the end of the liquid crystal backlight assembly and higher than those farther from the end of the liquid crystal backlight assembly, and the first pressing member and / or the second pressing member include:
[0024] The first set of cylindrical components has a recessed lower part to form a first inner cavity;
[0025] The second sleeve has its top extending into the first inner cavity, and the top of the second sleeve is connected to the top of the first inner cavity by a spring. The second sleeve forms a second inner cavity.
[0026] A guide rod is slidably connected to the second inner cavity, and a spring is sleeved on the guide rod.
[0027] Understandably, by setting up a structure formed by the combination of guide rod and spring, a buffering force can be provided to the pressing part when it is squeezed by the clamping part. Moreover, the setting of the guide rod can generate a buffering force while the pressing part as a whole will not shift laterally.
[0028] According to one embodiment provided in this application, when the first or second clamping member below the second sleeve can continue to slide, the spring remains in a stretched state. When the first or second clamping member below the second sleeve pushes the backlight assembly to a preset position and cannot move further, the second sleeve can continue to press down and cause the spring to contract until the second sleeve abuts against the top of the first inner cavity.
[0029] It is understood that the spring contraction only occurs after the first or second clamping member pushes the backlight assembly to the preset position. Before the backlight assembly moves to the preset position, the spring does not affect the corrective movement of the backlight assembly. This can be achieved through the selection of spring materials. Under normal pressure (the pressure on the spring before the backlight assembly moves to the preset position), the spring, based on its own strength and hardness, will not deform due to the thrust. However, after the backlight assembly is pushed to the preset position, the pressure on the spring will continuously increase until it reaches a level that affects its deformation.
[0030] According to one embodiment provided in this application, a sensor is provided at the top of the first inner cavity. The sensor is a photoelectric sensor or a contact sensor. When the second sleeve abuts against the top of the first inner cavity, the sensor receives a contact signal and feeds it back to the control unit. The control unit knows that the backlight assembly has reached a preset position based on the received contact signal.
[0031] According to one embodiment provided in this application, after the first driving member drives the pressure plate to the limit position, each of the bearing plates is reset. The control unit identifies the backlight assembly that has not reached the preset position and marks the part of the backlight assembly for post-processing.
[0032] It is understandable that the post-processing method can be to perform a secondary inspection to determine whether it is a defective product. If it is a good product, it can be further verified whether the failure is due to a fault in the high load-bearing capacity light source positioning structure of this embodiment. Alternatively, it can be to directly verify whether the failure is due to a fault in the high load-bearing capacity light source positioning structure of this embodiment, or to directly reposition the backlight assembly.
[0033] According to one embodiment of this application, a pull-out tray is provided on the bearing shelf, and the positioning and correction component is disposed on the tray.
[0034] Understandably, after the backlight assembly is positioned, it can be moved off the rack using a tray to facilitate its transfer to the downstream workstation for assembly with the LCD panel.
[0035] A liquid crystal component provided in the second aspect of this application is prepared by the following method:
[0036] The backlight assembly positioned by the high load-bearing capacity light source positioning structure provided in the first aspect of this application;
[0037] The control unit obtains the preset position of each backlight component, and based on the preset position, uses a robotic arm to assemble and transfer the LCD panel to the preset position so that the LCD panel is accurately connected to the positioned backlight component.
[0038] It is understandable that after the backlight assembly is positioned by the high load-bearing capacity light source positioning structure provided in the first aspect of this application, the LCD panel assembly can be performed to ensure the relative position between the backlight assembly and the LCD panel and improve the assembly accuracy.
[0039] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0048] This application provides an embodiment of a noise reduction and vibration damping bracket for electromechanical equipment. It should be noted that although the distribution and connection of related technical features are shown in the structural schematic diagram, in some embodiments, the related technical features can complete the shown or described methods in different distribution and connection ways.
[0049] The following is combined Figures 1-4 This application proposes a high load-bearing capacity light source positioning structure, which can at least achieve accurate positioning of backlight components and has high load-bearing capacity, enabling the positioning of batch backlight components.
[0050] A high-load-bearing capacity light source positioning structure according to a first aspect embodiment of this application includes:
[0051] The support plate 1 has multiple sets arranged in a vertical direction. Each set of support plate 1 has several light source support positions 11, which are used to support the liquid crystal backlight assembly.
[0052] The pressure plate 2 is connected to the driving end of the first driving member 3. The first driving member 3 is used to drive the pressure plate 2 to press down the uppermost bearing plate 1 and to make each bearing plate 1 press down the bearing plate 1 located below it.
[0053] The counterweight 4, except for the bottommost bearing plate 1, is connected to at least one counterweight 4 for each bearing plate 1. The counterweight 4 is used to apply an upward pulling force to the bearing plate so that each bearing plate applies the same pressure to the bearing plate 1 below it.
[0054] Positioning and correction component 5 is disposed on the support plate 1. During the pressing process of the pressure plate 2 or the support plate 1, the positioning and correction component 5 is driven synchronously to push the liquid crystal backlight component to move to the preset position.
[0055] The high load-bearing capacity light source positioning structure of the present application embodiment can produce the following technical effects:
[0056] The first driving component 3 drives the pressure plate 2 to press down the uppermost support layer 1. The uppermost support layer 1 presses down the support layer 1 below it, and then presses down the support layer 1 below it. During the pressing process, the pressure plate 2 or the support layer 1 simultaneously drives the positioning and correction component 5 to move the LCD backlight assembly to a preset position, thereby achieving precise positioning and correction of the LCD backlight assembly. At the same time, since each support layer 1 except the lowermost support layer 1 is connected to at least one counterweight 4, the support layer 1 is subjected to pressure. An upward pulling force is applied so that each load-bearing layer exerts the same pressure on the load-bearing layer 1 below it. This arrangement avoids the influence of the weight of the load-bearing layer 1 itself on the downward pressure, which would cause the positioning and correction components 5 on the light source support positions 11 on the lower load-bearing layer 1 to experience greater pressure than the positioning and correction components 5 on the upper light source support positions 11. Based on this, the high load-bearing capacity light source positioning structure has high load-bearing capacity, enabling simultaneous positioning of light source components on multiple light source support positions 11 in the multi-layer load-bearing layer 1.
[0057] Specifically, in this embodiment, the first driving member 3 can be a linear driving member that directly drives the pressure plate 2 to move downwards, or it can be as follows: Figure 4 As shown, the first driving member 3 can be a rotary driving member. When the first driving member 3 is a rotary driving member, the driving end of the first driving member 3 is connected to the first gear 31. The guide rod 763 that passes through each bearing plate 1 is a screw. The screw is sleeved with the second gear 32. The first gear 31 and the second gear 32 are connected by a transmission belt or by gear meshing.
[0058] Understandably, the guide rod 763 is connected to the bottom bearing plate 1 and the top fixing seat at both ends. The fixing seat is used to fix the first driving member 3, and the driving end of the first driving member 3 passes through the fixing seat.
[0059] Preferably, a chain 13 is provided between the pressure plate 2 and the bearing plate 1, and between adjacent bearing plates 1. In the initial state, the chain 13 is straight. After the positioning work is completed, when the pressure plate 2 rises and resets, the chain 13 can drive each bearing plate 1 to reset to the initial position.
[0060] According to an embodiment provided in this application, the positioning and correction component 5 is configured to correspond one-to-one with the light source carrier position 11. The positioning and correction component 5 includes a first clamping member 51 and a second clamping member 52 that slides with the carrier plate 1. A corresponding light source carrier position 11 is formed between the first clamping member 51 and the second clamping member 52 for placing the liquid crystal backlight component.
[0061] During the process of the support plate 1 with the positioning and correction component 5 being pressed down by the support plate 1 above it, the pressure plate 2 or the support plate 1 above the positioning and correction component 5 synchronously drives the positioning and correction component 5 to push the first clamping member 51 and the second clamping member 52 in the positioning and correction component 5 closer to each other, so that the liquid crystal backlight component located between the first clamping member 51 and the second clamping member 52 tends to a preset position.
[0062] According to one embodiment provided in this application, it also includes
[0063] The pressing component 6 is configured one-to-one with the positioning and correction component 5 and is located on the lower surface of the pressure plate 2 or the support layer 1 above the corresponding positioning and correction component 5. The pressing component 6 includes a first pressing member 61 and a second pressing member 62. When the pressure plate 2 or the support layer 1 presses down on the support layer 1 below it, the first pressing member 61 and the second pressing member 62 press down on the first clamping member 51 and the second clamping member 52 respectively, so that the first clamping member 51 and the second clamping member 52 move closer to each other and make the liquid crystal backlight assembly located between the first clamping member 51 and the second clamping member 52 tend to a preset position.
[0064] According to one embodiment provided in this application, the bottom of the first pressing member 61 is rolledly connected to a first pressure roller 611, and the first pressure roller 611 rollsly engages with the top surface of the first pressing member 51 located below it.
[0065] The bottom of the second pressing member 62 is rolledly connected to a second pressure roller 621, and the second pressure roller 621 rolls into contact with the top surface of the second pressing member 52 located below it.
[0066] It is understandable that by using a rolling contact method, the friction between the pressing component and the clamping component during the downward correction process is reduced, thereby improving the structural life and making the movement more stable and controllable.
[0067] According to one embodiment provided in this application, the top surfaces of the first clamping member 51 and the second clamping member are inclined surfaces that are closer to the end of the liquid crystal backlight assembly and higher than those farther from the end of the liquid crystal backlight assembly. The first pressing member 61 and / or the second pressing member 62 include:
[0068] The first cylindrical component 612 has a recessed lower part to form a first inner cavity 6121;
[0069] The second sleeve 622 has its top extending into the first inner cavity 6121. The top of the second sleeve 622 is connected to the top of the first inner cavity 6121 by a spring 631. The second sleeve 622 forms the second inner cavity 6221.
[0070] Guide rod 763 is slidably connected to the second inner cavity 6221, and spring 631 is sleeved on guide rod 763.
[0071] Understandably, by setting up a structure formed by the combination of guide rod 763 and spring 631, a buffering force can be provided to the pressing member when it is squeezed by the clamping member. Moreover, the setting of guide rod 763 can generate a buffering force while the pressing member as a whole will not shift laterally.
[0072] According to one embodiment provided in this application, when the first clamping member 51 or the second clamping member 52 below the second sleeve 622 can continue to slide, the spring 631 remains in a stretched state. When the first clamping member 51 or the second clamping member 52 below the second sleeve 622 pushes the backlight assembly to a preset position and can no longer move, the second sleeve 622 can continue to press down and cause the spring 631 to contract until the second sleeve 622 abuts against the top of the first inner cavity 6121.
[0073] It is understandable that the contraction of spring 631 only occurs after the first clamping member 51 or the second clamping member 52 pushes the backlight assembly to the preset position. Before the backlight assembly moves to the preset position, spring 631 does not affect the corrective movement of the backlight assembly. This can be achieved through the selection of materials for spring 631. Under normal pressure (the pressure on spring 631 before the backlight assembly moves to the preset position), spring 631, based on its own strength and hardness, will not deform due to the pushing force. However, after the backlight assembly is pushed to the preset position, the pressure on spring 631 will continue to increase until it reaches a level that can affect its deformation.
[0074] According to one embodiment provided in this application, a sensor 6122 is provided at the top of the first inner cavity 6121. The sensor 6122 is a photoelectric sensor or a contact sensor. When the second sleeve 622 abuts against the top of the first inner cavity 6121, the sensor 6122 receives a contact signal and feeds it back to the control unit. The control unit knows that the backlight assembly has reached a preset position based on the received contact signal.
[0075] According to one embodiment provided in this application, after the first driving member 3 drives the pressure plate 2 to the limit position, each bearing plate 1 is reset, the control unit identifies the backlight assembly that has not reached the preset position, and marks the backlight assembly for post-processing.
[0076] It is understandable that the post-processing method can be to perform a secondary inspection to determine whether it is a defective product. If it is a good product, it can be further verified whether the failure is due to a fault in the high load-bearing capacity light source positioning structure of this embodiment. Alternatively, it can be to directly verify whether the failure is due to a fault in the high load-bearing capacity light source positioning structure of this embodiment, or to directly reposition the backlight assembly.
[0077] According to one embodiment provided in this application, a pull-out tray 12 is provided on the support layer 1, and positioning and correction components 5 are all provided on the tray 12.
[0078] Understandably, after the backlight assembly is positioned, it can be moved out of the rack via tray 12 to facilitate its transfer to the downstream workstation for assembly with the LCD panel.
[0079] A liquid crystal component provided in the second aspect of this application is prepared by the following method:
[0080] The backlight assembly positioned by the high load-bearing capacity light source positioning structure provided in the first aspect of this application;
[0081] The control unit obtains the preset position of each backlight component, and based on the preset position, the robot arm assembles and transfers the LCD panel to the preset position so that the LCD panel is accurately connected to the positioned backlight component.
[0082] It is understandable that after the backlight assembly is positioned by the high load-bearing capacity light source positioning structure provided in the first aspect of this application, the LCD panel assembly can be performed to ensure the relative position between the backlight assembly and the LCD panel and improve the assembly accuracy.
[0083] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.
[0084] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment can be implemented by means of software plus necessary general-purpose hardware platforms, and of course, it can also be implemented by hardware. Based on this understanding, the above technical solutions, in essence or the part that contributes to the prior art, can be embodied in the form of a software product.
