Description

Technical Field

[0001] This invention relates to the field of liquid crystal module technology, and in particular to an assembly structure for a liquid crystal display module. Background Technology

[0002] Simply put, an LCD module consists of a screen and a backlight assembly. The display component of an LCD TV is the LCD module, which is equivalent to the picture tube in a CRT. Other parts include power supply circuits, signal processing circuits, and of course, the casing. The module is mainly divided into the screen and the backlight assembly. The two parts are assembled together, but they work independently (i.e., the circuits are unrelated). The principle of LCD display is that the backlight assembly emits uniform surface light, which is transmitted to the eyes through the LCD screen. The screen's function is to process this light according to pixels to display images.

[0003] In the production process of LCD modules, multiple components of the LCD module need to be assembled. During the assembly process, glue needs to be applied to the back of the glass panel, which then bonds the glass panel to the backlight module.

[0004] Based on existing technology, the following problems exist in the assembly process of LCD modules:

[0005] 1. After the LCD module is assembled, it cannot be easily removed from inside the fixture, resulting in low work efficiency;

[0006] 2. When assembling the LCD module, the glass panel is prone to bumping against the assembly frame when it is lowered during assembly of the backlight module, which can damage the glass panel and reduce assembly efficiency. Summary of the Invention

[0007] This invention provides an assembly structure for a liquid crystal display module, which solves the problems of the liquid crystal module being difficult to remove from the fixture, resulting in low work efficiency, and the glass panel easily colliding with the assembly frame during descent, causing damage to the glass panel and low assembly efficiency.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An assembly structure for a liquid crystal display module includes an operating platform. An assembly frame is bolted to the top of the operating platform, and a lifting mechanism is provided within the assembly frame. The lifting mechanism includes mounting plates fixed at both ends to the inner walls of both sides of the operating platform and four lifting cylinders bolted to the outer bottom wall of the mounting plates. A limit frame is bolted to one end of the top of the operating platform, and a support mechanism is provided within the limit frame. The support mechanism includes a mounting cylinder and a gear ring fixed to the upper outer wall of the mounting cylinder. A rotating assembly is provided above the mounting cylinder. The rotating assembly includes an adjusting plate with two slide rails on its top outer wall, a rotary motor and gear bolted to the outer top wall of the adjusting plate, and a displacement assembly on the top of the adjusting plate. The displacement assembly includes a pushing cylinder, a connecting block bolted to the outer wall of one end of the piston rod of the pushing cylinder, and a mounting block that slides with the adjusting plate. A flipping assembly is provided on one side of the mounting block. The flipping assembly includes a flipping motor bolted to the outer wall of one side of the mounting block, a rotating platform fixed to the outer wall of one end of the output shaft of the flipping motor, a connecting seat fixed to the outer wall of one side of the rotating platform, a connecting shaft fixed to the outer wall of one side of the connecting seat, and a connecting plate connected to the outer wall of the connecting shaft via a bearing. A lifting assembly is provided at the top of the connecting seat. The lifting assembly includes a mounting platform, four lifting cylinders bolted to the outer wall of the top of the connecting seat, and four vacuum suction cups screwed to the outer wall of the top of the mounting platform.

[0010] Preferably, the top of the operating table has four mounting holes on the outer wall inside the assembly frame, and a lifting plate is slidably installed in each of the four mounting holes. The bottom of the four lifting plates is fixed to the outer wall of the top of the piston rod of the four lifting cylinders.

[0011] The above scheme uses four lifting cylinder piston rods to rise, which in turn drives four lifting plates to rise. The lifting plates lift the backlight module inside the assembly frame and eject the assembled LCD module.

[0012] Preferably, the top of the operating platform is connected to a support column by bolts on the outer wall inside the limiting frame, and the mounting cylinder is fixed to the top outer wall of the support column.

[0013] Preferably, a rotating cylinder is fixed on the bottom outer wall of the adjusting plate, and the rotating cylinder is connected to the upper inner wall of the mounting cylinder through a bearing. A rotating shaft is connected to the bottom outer wall of the output shaft of the rotating motor through a coupling, and a gear is fixed on the lower outer wall of the rotating shaft. The gear and the gear ring mesh with each other to form a transmission fit. Two stabilizing rods are fixed on the bottom outer wall of the adjusting plate, and the two stabilizing rods are slidably installed in the limiting frame.

[0014] The above scheme moves the connecting block and mounting block by pushing the piston rod of the cylinder, so that the rotary table is located outside the adjusting plate. The output shaft of the rotary motor drives the gear to rotate, and the gear rotates along the gear ring, which in turn drives the adjusting plate to rotate along the axis of the mounting cylinder, thus driving the glass panel to rotate.

[0015] Preferably, a mounting base is fixed on the top outer wall of the adjusting plate, and one end of the pushing cylinder is bolted to the outer wall of one side of the mounting base. A fixing base is fixed on the top outer wall of the adjusting plate, and the fixing base is bolted to the outer wall of one end of the pushing cylinder. Four connecting rods are fixed on the top outer wall of the mounting block, and the four connecting rods are slidably installed in two slides in pairs. The bottom of the connecting block is fixed on the top outer wall of the four connecting rods.

[0016] Preferably, two limiting rods are fixed on the upper outer wall of one side of the connecting plate, and two limiting plates are fixed on the top outer wall of the adjusting plate. The two limiting rods are respectively inserted through and slidably installed on the outer wall of one side of the two limiting plates, and a limiting block is screwed onto the outer wall of one end of each of the two limiting rods.

[0017] Preferably, the top of the mounting platform is fixed to the outer wall of the bottom end of the piston rod of the four lifting cylinders, and a connecting hose is fixed to the upper outer wall of each of the four vacuum suction cups, and the four connecting hoses are respectively connected to the vacuum pump.

[0018] The above scheme uses four lifting cylinder piston rods to lift and lower, which in turn drives the connecting seat to lift and lower, which in turn drives four vacuum suction cups to lift and lower and adsorb the glass panel. The output shaft of the flip motor rotates, which drives the turntable and the connecting seat to rotate along the axis of the connecting shaft, causing the glass panel to flip and apply adhesive to the back of the glass panel. Then the flip motor drives the glass panel to flip again, and then the lifting cylinder drives the glass panel to descend steadily.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. It is equipped with an assembly frame and a lifting mechanism. The piston rods of four lifting cylinders rise, driving four lifting plates to rise. The lifting plates lift the backlight module in the assembly frame and push out the assembled LCD module. This allows for convenient removal of the assembled LCD module, improving work efficiency.

[0021] 2. Equipped with a flipping component and a lifting component, four lifting cylinder piston rods rise and fall, driving the connecting seat to rise and fall, which in turn drives four vacuum suction cups to rise and fall and adsorb the glass panel. The output shaft of the flipping motor rotates, causing the rotary table and connecting seat to rotate along the axis of the connecting shaft, causing the glass panel to flip and apply adhesive to the back of the glass panel. Then the flipping motor drives the glass panel to flip again, and then the lifting cylinders drive the glass panel to descend steadily. This allows for convenient application of adhesive to the back of the glass panel and a stable descent, preventing the glass panel from being bumped or damaged, and improving assembly efficiency.

[0022] In summary, this invention enables convenient ejection of the assembled liquid crystal module, facilitating its removal and improving work efficiency. It also allows for easy application of adhesive to the back of the glass panel and stable descent of the glass panel, preventing collisions and further enhancing assembly efficiency.
