Description

Technical Field

[0001] The present application relates to the technical field of liquid crystal modules, and in particular to a high-load-bearing light source positioning structure and a liquid crystal module. Background Art

[0002] The liquid crystal display module uses a liquid crystal solution in two polarized materials, so that when the current passes through the liquid, the crystals are rearranged to achieve the purpose of imaging. When the current passes through the liquid, the crystals are rearranged so that light cannot pass through them. Therefore, each crystal is like a shutter, which can allow light to pass through and block light. The liquid crystal display module is developing towards the goal of being light, thin, short and small, and the display products with a long history in computer peripherals are of course no exception. Under the premise of being easy to carry and transport, traditional display methods such as CRT image tube displays and LED display panels, etc., are all subject to factors such as large size or huge power consumption, and cannot meet the actual needs of users. The development of liquid crystal display technology just fits the current trend of information products. Whether it is right-angle display, low power consumption, small size, or zero radiation, it can allow users to enjoy the best visual environment.

[0003] The LCD panel and backlight assembly are important components of the LCD module. The LCD panel is placed above the light-emitting surface of the backlight assembly and is usually supported by the bearing part of the frame. A certain distance needs to be maintained between the LCD panel and the backlight assembly to ensure that light is evenly transmitted through the LCD panel. The backlight assembly and the LCD panel need to be accurately positioned to ensure that the light emitted by the backlight is evenly transmitted through the LCD panel to avoid uneven brightness or dark areas. This is crucial to improving display quality, as uneven light can cause images to appear mottled or blurred. In addition, accurate positioning helps achieve better contrast and color reproduction capabilities, and correct installation and positioning can reduce friction and stress between the LCD panel and the backlight module, thereby extending the service life of the entire LCD module.

[0004] However, during 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 loading process is one of the reasons for the large relative position deviation between the LCD panel and the backlight assembly. Summary of the invention

[0005] The present application aims to solve at least one of the technical problems existing in the related art. To this end, the present application proposes a high-load-bearing light source positioning structure, which can at least achieve accurate positioning of the backlight source assembly and has high load-bearing capacity, and can achieve the positioning of batch backlight source assemblies.

[0006] A high-load-bearing light source positioning structure according to an embodiment of the first aspect of the present application includes:

[0007] The bearing layer plates are provided with a plurality of groups arranged in a vertical direction, each group of the bearing layer plates is provided with a plurality of light source bearing positions, and the light source bearing positions are used to bear the liquid crystal backlight source assembly;

[0008] A pressing plate connected to the driving end of the first driving member, the first driving member is used to drive the pressing plate to press down the uppermost bearing layer plate, and make each bearing layer plate press down the bearing layer plate located below it;

[0009] A counterweight block, except for the bottom load-bearing layer plate, each group of the load-bearing layer plates is connected to at least one counterweight block, and the counterweight block 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 layer plate located below it;

[0010] A positioning and deflection correction component is arranged on the bearing layer plate, and is synchronously driven during the pressing process of the pressing plate or the bearing layer plate to push the liquid crystal backlight source assembly to move to a preset position.

[0011] The high-load-bearing light source positioning structure of the embodiment of the present application can produce the following technical effects:

[0012] The first driving member drives the pressure plate to press down the uppermost bearing layer, and the uppermost bearing layer presses down the bearing layer below it, and then presses down the bearing layer below it. During the pressing process, the pressure plate or the bearing layer synchronously drives the positioning and correcting component to push the liquid crystal backlight source component to move to a preset position, thereby realizing precise correction and positioning of the liquid crystal backlight source component. At the same time, each group of bearing layers except the lowermost bearing layer is connected with at least one counterweight block, thereby applying an upward pulling force to the bearing plate, so that each bearing plate applies the same pressure to the bearing layer below it. Such a setting can avoid the influence of the gravity of the bearing layer itself on the downward pressure, resulting in the positioning and correcting component on the light source bearing position on the lower bearing layer being subjected to greater pressure than the positioning and correcting component on the upper light source bearing position. Based on this, the high-bearing-capacity light source positioning structure has high bearing capacity, and the simultaneous positioning of the light source components on multiple light source bearing positions in the multi-layer bearing layer is realized.

[0013] Specifically, the first driving member of 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 the first gear, and the guide rod passing through each load-bearing layer plate is a screw rod, and the screw rod is sleeved with a second gear. The first gear and the second gear are connected by a transmission belt transmission connection or a gear meshing transmission connection.

[0014] It can be understood that the two ends of the guide rod are connected to the lowest bearing layer plate and the uppermost fixing seat, the fixing seat is used to fix the first driving member, and the driving end of the first driving member passes through the fixing seat.

[0015] Preferably, chains are provided between the pressing plate and the bearing layers and between adjacent bearing layers. In the initial state, the chains are in a straight state. After completing the positioning work, when the pressing plate rises and resets, the chains can drive each bearing layer to reset to the initial position.

[0016] According to an embodiment provided by the present application, the positioning and correcting assembly is arranged in one-to-one correspondence with the light source bearing position, and the positioning and correcting assembly includes a first pressing clamp and a second pressing clamp that are slidably matched with the bearing layer plate, and the corresponding light source bearing position is formed between the first pressing clamp and the second pressing clamp for placing the liquid crystal backlight source assembly;

[0017] During the process that the bearing layer plate provided with the positioning and correcting components is pressed down by the bearing layer plate located above it, the pressure plate or the bearing layer plate located above the group of positioning and correcting components synchronously drives the group of positioning and correcting components to push the first pressing clamp and the second pressing clamp in the group of positioning and correcting components to approach each other, so that the liquid crystal backlight source assembly located between the first pressing clamp and the second pressing clamp tends to a preset position.

[0018] According to an embodiment provided by the present application, it also includes

[0019] A pressing component is arranged in one-to-one correspondence with the positioning and correcting components, and is arranged at the lower surface position of the pressure plate or the bearing layer above the corresponding positioning and correcting components. The pressing component includes a first pressing member and a second pressing member. When the pressure plate or the bearing layer presses down the bearing layer thereunder, the first pressing member and the second pressing member press down the first pressing member and the second pressing member respectively, so that the first pressing member and the second pressing member are close to each other, and the liquid crystal backlight source assembly located between the first pressing member and the second pressing member tends to a preset position.

[0020] According to an embodiment provided by the present application, a first pressing roller wheel is rollingly connected to the bottom of the first pressing member, and the first pressing roller wheel is rollingly matched with the top surface of the first pressing clamping member located therebelow;

[0021] The bottom of the second pressing member is rollingly connected with a second pressing roller wheel, and the second pressing roller wheel is rollingly matched with the top surface of the second pressing clamping member located therebelow.

[0022] It can be understood that the rolling fit can reduce the friction between the pressing part and the clamping part during the pressing and correcting process, thereby increasing the life of the structure and making the movement smoother and more controllable.

[0023] According to an embodiment provided by the present application, the top surfaces of the first pressing member and the second pressing member are inclined surfaces closer to the end of the liquid crystal backlight source assembly than the end away from the liquid crystal backlight source, and the first pressing member and / or the second pressing member include:

[0024] A first sleeve member, wherein the lower portion of the first sleeve member is concave to form a first inner cavity;

[0025] a second sleeve member, wherein the top of the second sleeve member is inserted into the first inner cavity, the top of the second sleeve member is connected to the top of the first inner cavity via a spring, and the second sleeve member forms a second inner cavity;

[0026] A guide rod is slidably connected to the second inner cavity, and the spring is sleeved on the guide rod.

[0027] It can be understood that by setting up a structure formed by a guide rod and a spring combination, a buffering force can be applied to the lower pressing member when the lower pressing member is squeezed with the clamping member, and the setting of the guide rod can generate a buffering force while the lower pressing member as a whole will not be laterally offset.

[0028] According to an embodiment provided by the present application, when the first pressing clamp or the second pressing clamp under the second sleeve member can continue to slide, the spring remains in a stretched state, and when the first pressing clamp or the second pressing clamp under the second sleeve member pushes the backlight source assembly to a preset position and cannot move further, the second sleeve member can continue to press down to contract the spring until the second sleeve member abuts against the top of the first inner cavity.

[0029] It is understandable that the contraction of the spring will only occur after the first clamp or the second clamp pushes the backlight assembly to the preset position, and when the backlight assembly has not yet moved to the preset position, the spring does not affect the deviation-correcting movement of the backlight assembly. The above method can be achieved through the selection of the material of the spring, that is, when the spring is subjected to normal pressure (referring to the pressure on the spring when the backlight assembly has not yet moved to the preset position), based on its own strength and hardness, it will not be deformed by the thrust, and after the backlight assembly is pushed to the preset position, the pressure on the spring will continue to increase until the pressure increases to a level that can affect its deformation.

[0030] According to an embodiment provided in the present application, a sensing element is provided at the top of the first inner cavity, and the sensing element is a photoelectric sensor or a contact sensor. When the second sleeve element abuts against the top of the first inner cavity, the sensing element receives a contact signal and feeds back to a control unit. The control unit knows that the backlight source assembly has reached a preset position based on the received contact signal.

[0031] According to an embodiment provided in the present application, after the first driving member drives the pressure plate down to the extreme position, each of the bearing layer plates is reset, and the control unit recognizes that the backlight source assembly has not reached the preset position, and marks this part of the backlight source assembly for post-processing.

[0032] It is understandable that the post-processing method can be to conduct a secondary inspection to determine whether it is a defective product. In the case of a good product, further verify whether the failure is the high-load-bearing light source positioning structure of this embodiment. It can also be to directly verify whether the failure is the high-load-bearing light source positioning structure of this embodiment, or directly re-position the backlight source assembly.

[0033] According to an embodiment provided in the present application, a tray which is drawably connected to the bearing layer is disposed on the bearing layer, and the positioning and correcting assembly and the positioning and correcting assembly are both disposed on the tray.

[0034] It is understandable that after the backlight source assembly is positioned, the positioned backlight source assembly can be moved out of the rack via a tray so as to be transferred to a downstream station for assembly with the liquid crystal panel.

[0035] A second aspect of the present application provides a liquid crystal component, which is prepared by the following method:

[0036] A backlight source assembly positioned by the high-load-bearing light source positioning structure provided by the first aspect of the present application;

[0037] The control unit obtains the preset position of each backlight source assembly, and based on the preset position, transfers the liquid crystal panel assembly to the preset position through a robot, so that the liquid crystal panel is accurately connected to the positioned backlight source assembly.

[0038] It can be understood that after the backlight source assembly is positioned by the high-load-bearing light source positioning structure provided in the first aspect of the present application, the liquid crystal panel is assembled to ensure the relative position between the backlight source assembly and the liquid crystal panel and improve the assembly accuracy.

[0039] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] The embodiments of the present application provide embodiments of noise reduction and shock absorbing brackets for electromechanical equipment. It should be noted that although the distribution and connection methods between related technical features are shown in the structural schematic diagram, in certain embodiments, each related technical feature can be distributed and connected in different ways to complete the methods shown or described.

[0048] Combine the following Figure 1-Figure 4 Description The present application proposes a high-load-bearing light source positioning structure, which can at least realize the precise positioning of a backlight source assembly and has high load-bearing capacity, and can realize the positioning of batches of backlight source assemblies.

[0049] A high-load-bearing light source positioning structure according to an embodiment of the first aspect of the present application includes:

[0050] The bearing layer plate 1 is provided with a plurality of groups arranged in a vertical direction, and each group of the bearing layer plates 1 is provided with a plurality of light source bearing positions 11, and the light source bearing positions 11 are used to bear the liquid crystal backlight source assembly;

[0051] The pressing plate 2 is connected to the driving end of the first driving member 3, and the first driving member 3 is used to drive the pressing plate 2 to press down the uppermost bearing layer 1, and make each bearing layer 1 press down the bearing layer 1 located below it;

[0052] A counterweight block 4, except for the bottom load-bearing layer 1, each group of load-bearing layers 1 is connected to at least one counterweight block 4, and the counterweight block 4 is used to apply an upward pulling force to the load-bearing plates, so that each load-bearing plate applies the same pressure to the load-bearing layer 1 located below it;

[0053] The positioning and correcting component 5 is arranged on the bearing layer 1. When the pressing plate 2 or the bearing layer 1 is pressed down, the positioning and correcting component 5 is synchronously driven to push the liquid crystal backlight source component to move to a preset position.

[0054] The high-load-bearing light source positioning structure of the embodiment of the present application can produce the following technical effects:.

[0055] The first driving member 3 drives the pressing plate 2 to press down the uppermost bearing layer 1, and the uppermost bearing layer 1 presses down the bearing layer 1 below it, and then presses down the bearing layer 1 further below. During the pressing process, the pressing plate 2 or the bearing layer 1 synchronously drives the positioning and correcting component 5 to push the liquid crystal backlight source component to a preset position, thereby realizing accurate correction and positioning of the liquid crystal backlight source component. At the same time, each group of bearing layers 1 except the lowermost bearing layer 1 is connected with at least one counterweight 4, thereby applying an upward pulling force to the bearing plate, so that each bearing plate applies the same pressure to the bearing layer 1 below it. Such a setting can avoid the influence of the gravity of the bearing layer 1 itself on the downward pressure, resulting in the positioning and correcting component 5 on the light source bearing position 11 on the lower bearing layer 1 being subjected to greater pressure than the positioning and correcting component 5 on the upper light source bearing position 11. Based on this, the high-bearing-capacity light source positioning structure has high bearing capacity, and the simultaneous positioning of the light source components on multiple light source bearing positions 11 in the multi-layer bearing layer 1 is realized.

[0056] Specifically, the first driving member 3 of this embodiment can be a linear driving member that directly drives the pressing plate 2 to move downward, or can be a linear driving member that directly drives the pressing plate 2 to move downward. Figure 4 As shown, the first driving member 3 can be a rotating driving member. In the case where the first driving member 3 is a rotating driving member, the driving end of the first driving member 3 is connected to the first gear 31, and the guide rod 763 passing through each bearing layer plate 1 is a screw rod, and the screw rod is sleeved with the second gear 32. The first gear 31 and the second gear 32 are connected by a transmission belt transmission or a gear meshing transmission.

[0057] It can be understood that the two ends of the guide rod 763 are connected to the lowest bearing layer plate 1 and the highest fixing seat, and 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.

[0058] Preferably, a chain 13 is provided between the pressing plate 2 and the load-bearing layer 1 and between adjacent load-bearing layer 1. In the initial state, the chain 13 is in a straight state. After completing the positioning work, when the pressing plate 2 rises and resets, the chain 13 can drive each load-bearing layer 1 to reset to the initial position.

[0059] According to an embodiment provided by the present application, the positioning and correcting assembly 5 is arranged in one-to-one correspondence with the light source bearing position 11, and the positioning and correcting assembly 5 includes a first pressing member 51 and a second pressing member 52 that are slidably matched with the bearing layer plate 1, and a corresponding light source bearing position 11 is formed between the first pressing member 51 and the second pressing member 52 for placing the liquid crystal backlight source assembly;

[0060] During the process that the bearing layer 1 provided with the positioning and correcting assembly 5 is pressed down by the bearing layer 1 located above it, the pressure plate 2 or the bearing layer 1 located above the group of positioning and correcting assemblies 5 synchronously drives the group of positioning and correcting assemblies 5 to push the first pressing clamp 51 and the second pressing clamp 52 in the group of positioning and correcting assemblies 5 to approach each other, so that the liquid crystal backlight source assembly located between the first pressing clamp 51 and the second pressing clamp 52 tends to a preset position.

[0061] According to an embodiment provided by the present application, it also includes

[0062] The pressing component 6 is arranged in one-to-one correspondence with the positioning and correcting components 5, and is arranged at the lower surface position of the pressure plate 2 or the bearing layer 1 above the corresponding positioning and correcting components 5. The pressing component 6 includes a first pressing member 61 and a second pressing member 62. When the pressure plate 2 or the bearing layer 1 presses down the bearing layer 1 thereunder, the first pressing member 61 and the second pressing member 62 press down the first pressing member 51 and the second pressing member 52 respectively, so that the first pressing member 51 and the second pressing member 52 are close to each other, and the liquid crystal backlight source component located between the first pressing member 51 and the second pressing member 52 tends to a preset position.

[0063] According to an embodiment provided by the present application, the bottom of the first pressing member 61 is rollingly connected to a first pressing roller 611, and the first pressing roller 611 is rollingly matched with the top surface of the first pressing clamp 51 located therebelow;

[0064] The bottom of the second pressing member 62 is rollingly connected to a second pressing roller 621 , and the second pressing roller 621 is rollingly matched with the top surface of the second pressing clamp 52 located therebelow.

[0065] It can be understood that the rolling fit can reduce the friction between the pressing part and the clamping part during the pressing and correcting process, thereby increasing the life of the structure and making the movement smoother and more controllable.

[0066] According to an embodiment provided by the present application, the top surfaces of the first pressing member 51 and the second pressing member are inclined surfaces close to the end of the liquid crystal backlight source assembly and higher than the end away from the liquid crystal backlight source, and the first pressing member 61 and / or the second pressing member 62 include:

[0067] A first sleeve member 612, wherein the lower portion of the first sleeve member 612 is concave to form a first inner cavity 6121;

[0068] A second sleeve member 622, the top of the second sleeve member 622 penetrates into the first inner cavity 6121, the top of the second sleeve member 622 is connected to the top of the first inner cavity 6121 through a spring 631, and the second sleeve forms a second inner cavity 6221;

[0069] The guide rod 763 is slidably connected to the second inner cavity 6221 , and the spring 631 is sleeved on the guide rod 763 .

[0070] It can be understood that by setting up a structure formed by the guide rod 763 and the spring 631, a buffering force can be applied to the lower pressing member when the lower pressing member and the clamping member are squeezed, and the setting of the guide rod 763 can generate a buffering force while the lower pressing member as a whole will not be laterally offset.

[0071] According to an embodiment provided in the present application, when the first pressing clamp 51 or the second pressing clamp 52 under the second sleeve member 622 can continue to slide, the spring 631 remains in a stretched state. When the first pressing clamp 51 or the second pressing clamp 52 under the second sleeve member 622 pushes the backlight source assembly to a preset position and cannot move further, the second sleeve member 622 can continue to press down to contract the spring 631 until the second sleeve member 622 abuts against the top of the first inner cavity 6121.

[0072] It is understandable that the contraction of the spring 631 will only occur after the first clamp 51 or the second clamp 52 pushes the backlight assembly to the preset position, and when the backlight assembly has not yet moved to the preset position, the spring 631 does not affect the deviation-correcting movement of the backlight assembly. The above method can be achieved by selecting the material of the spring 631, that is, when the spring 631 is subjected to normal pressure (referring to the pressure on the spring 631 when the backlight assembly has not yet moved to the preset position), based on its own strength and hardness, it will not be deformed by the thrust, and after the backlight assembly is pushed to the preset position, the pressure on the spring 631 will continue to increase until the pressure increases to a level that can affect its deformation.

[0073] According to an embodiment provided in the present application, a sensing element 6122 is provided at the top of the first inner cavity 6121. The sensing element 6122 is a photoelectric sensor or a contact sensor. When the second sleeve element 622 abuts against the top of the first inner cavity 6121, the sensing element 6122 receives a contact signal and feeds back to the control unit. The control unit knows that the backlight source assembly has reached a preset position based on the received contact signal.

[0074] According to an embodiment provided in the present application, after the first driving member 3 drives the pressure plate 2 to be pressed down to the extreme position, each bearing layer plate 1 is reset, and the control unit recognizes that the backlight source assembly has not reached the preset position, and marks this part of the backlight source assembly for post-processing.

[0075] It is understandable that the post-processing method can be to conduct a secondary inspection to determine whether it is a defective product. In the case of a good product, further verify whether the failure is the high-load-bearing light source positioning structure of this embodiment. It can also be to directly verify whether the failure is the high-load-bearing light source positioning structure of this embodiment, or directly re-position the backlight source assembly.

[0076] According to an embodiment provided in the present application, a tray 12 which is drawably connected to the load-bearing layer 1 is disposed on the load-bearing layer 1 , and the positioning and correcting assembly 5 and the positioning and correcting assembly 5 are both disposed on the tray 12 .

[0077] It is understandable that after the backlight source assembly is positioned, the positioned backlight source assembly can be moved out of the rack via the tray 12 so as to be transferred to a downstream station for assembly with the liquid crystal panel.

[0078] A second aspect of the present application provides a liquid crystal component, which is prepared by the following method:

[0079] A backlight source assembly positioned by the high-load-bearing light source positioning structure provided by the first aspect of the present application;

[0080] The control unit obtains the preset position of each backlight source assembly, and based on the preset position, transfers the liquid crystal panel assembly to the preset position through a robot, so that the liquid crystal panel is accurately connected to the positioned backlight source assembly.

[0081] It can be understood that after the backlight source assembly is positioned by the high-load-bearing light source positioning structure provided in the first aspect of the present application, the liquid crystal panel is assembled to ensure the relative position between the backlight source assembly and the liquid crystal panel and improve the assembly accuracy.

[0082] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, i.e., they may be located in one place, or they may be distributed on multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the scheme of this embodiment. Those of ordinary skill in the art may understand and implement it without creative effort.

[0083] Through the description of the above implementation modes, those skilled in the art can clearly understand that each implementation mode can be implemented by means of software plus a necessary general hardware platform, or of course by hardware. Based on such an understanding, the above technical solution can essentially or in other words be embodied in the form of a software product that contributes to the prior art.
