Description

Technical Field

[0001] The utility model relates to the technical field of backlight module fixtures, in particular to a frame pressure-maintaining fixture. Background Art

[0002] At present, in the market, during the production of backlight modules, plastic frames are generally formed in one step; with the development of technology, aluminum frames are becoming more and more popular, with advantages such as good shaping and heat dissipation; however, aluminum frames need to match different models and sizes of backlight modules, so they need to be formed in a second step, and then the aluminum frames are attached to the backlight modules. If the frames are not pressurized, the colloid separation and light transmission between the frames and the backlight modules are likely to occur. The manual extrusion method is inefficient and has a high defect rate. Utility Model Content

[0003] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide a frame pressure-maintaining fixture to achieve the purpose of automatic pressure-maintaining.

[0004] The utility model provides a frame pressure-maintaining fixture, which is used for the frame pressure-maintaining of a backlight module; it comprises a frame, baffles, a cylinder assembly and a control module; two adjacent sides of the frame are respectively provided with a group of baffles; the other two sides of the frame are respectively provided with one or more groups of cylinder assemblies; the control module comprises an electromagnetic valve, a relay and a sensor linked with the cylinder assembly; when the sensor senses the backlight module, the cylinder assembly is controlled by the relay and the electromagnetic valve, and the relay adjusts the pressure-maintaining time of the cylinder assembly as required.

[0005] The material targeted by the utility model is a backlight module. After the backlight module is assembled with a frame, it is placed in a frame. The frame is rectangular and can surround the backlight module. The two adjacent sides are fixed sides, which are stressed by fixed baffles. The two opposite sides are movable sides. Through the movement of the cylinder assembly, the distance between the movable side and the fixed side is reduced, thereby achieving the purpose of maintaining pressure. The start of the cylinder assembly is controlled by a control module, wherein the relay is a time relay, which is used to control the duration of pressure maintenance. The solenoid valve controls the start and stop of the cylinder assembly. The sensor is used to sense whether there is material in the frame. When the material is placed, the start and stop of the cylinder assembly is controlled by the solenoid valve, and then the time relay is used to control the duration of pressure maintenance, thereby achieving automatic pressure maintenance, reducing manual operations, and improving the efficiency of pressure maintenance.

[0006] Furthermore, the cylinder assembly includes a mounting seat, a cylinder member, a push rod and a baffle; one end of the mounting seat is fixed to the side of the frame; the cylinder member is installed on the mounting seat; one end of the push rod is connected to the cylinder member, and the other end is connected to the baffle; the baffle is driven to move horizontally by the cylinder member to achieve pressure maintenance on the side of the backlight module.

[0007] The mounting seat plays the role of force bearing and installation and fixing. The mounting seat is a rectangular bar profile and can be fixed to the end face of the movable side of the mounting seat by screws or welding; the cylinder part can be fixed to the mounting seat by screws; because different backlight modules have different sizes, by setting the mounting seat in a long strip shape and installing the cylinder part in different positions, the length between the movable side and the fixed side of the frame can be adjusted, and 2 to 3 fixed gears can be set on the mounting seat to facilitate the installation of the cylinder part. To achieve the adjustment of the width of the frame.

[0008] Furthermore, the frame and / or mounting seat is an aluminum profile with a plurality of cavities inside.

[0009] In order to reduce the weight of the entire fixture and achieve the effect of light movement and convenient installation, the frame structure of the utility model is made of aluminum, which is light in weight. The weight can be reduced by setting a cavity. The frame and / or the mounting seat are square columns with strong load-bearing capacity.

[0010] Furthermore, the baffle includes a push plate and a pressure plate; one side of the push plate is connected to the push rod; the other side is attached to the pressure plate; the length of the pressure plate is greater than that of the push plate.

[0011] The push plate is fixed to the push rod. Since the frame of the backlight module has a plastic or metal frame, damage can be avoided during the pressure holding process. The utility model provides a pressure plate on the push plate. The length of the pressure plate is greater than the push plate. The pressure is transmitted through the double layer, so that the vibration during the pressure holding process is smaller and the pressure holding strength is more stable. In addition, a push plate of a certain area is separated between the push rod and the pressure plate, which can improve the uniformity of the force on the frame during the pressure holding process, thereby achieving a better pressure holding effect.

[0012] Furthermore, two groups of cylinder assemblies are respectively provided on the sides of two adjacent frames.

[0013] Since the movable side of the frame is long, if only a single cylinder assembly is used, the pressure at both ends of the pressure plate may be insufficient, resulting in poor pressure-maintaining effect. Therefore, the utility model combines actual needs and sets two groups of cylinder assemblies for each movable side. Each group of cylinder assemblies has two push rods, that is, two force points. Each movable side has four thrust points, which improves the uniformity of the pressure of the entire side.

[0014] Furthermore, the sensor is arranged at a corner of the frame; the solenoid valve and the relay are arranged at the ends of a group of the mounting seats.

[0015] Furthermore, the middle part of the frame is provided with multiple groups of cross beams, and the cross beams are provided with gaskets. The cross beams are also multi-cavity square columnar aluminum profiles, and the gaskets are used to protect the backlight module and avoid wear. The baffle is 90° angle aluminum.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model realizes the automation of the frame pressure maintenance of the backlight module, greatly improves the operation quality and efficiency, reduces the operation defects, reduces the potential safety hazards, and reduces the labor costs of the enterprise, achieving both quality and cost control. In addition, the pressure maintenance fixture of the utility model can be flexibly adjusted according to the size of the module, and has wider practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 3 As shown, the cylinder assembly 3 includes a mounting seat 31, a cylinder member 32, a push rod 33 and a baffle 34; Figure 1As shown, one end of the mounting seat 31 is fixed to the side of the frame 1; the cylinder 32 is installed on the mounting seat 31; one end of the push rod 33 is connected to the cylinder 32, and the other end is connected to the baffle 34; the baffle 34 is driven by the cylinder 32 to move horizontally to achieve pressure maintenance on the side of the backlight module. The mounting seat 31 plays the role of force bearing and installation and fixing. The mounting seat 31 is a rectangular strip profile, which can be fixed to the end face of the movable side of the mounting seat 31 by screws or welding; the cylinder 32 can be fixed to the mounting seat 31 by screws; because different backlight modules have different sizes, by setting the mounting seat 31 as a long strip and installing the cylinder 32 in different positions, the length between the movable side and the fixed side of the frame 1 can be adjusted, and 2 to 3 fixed gears can be set on the mounting seat 31 to facilitate the installation of the cylinder 32.
