Description

Technical Field

[0001] This utility model provides a bonding device for processing liquid crystal displays with auxiliary alignment function, belonging to the technical field of liquid crystal display bonding processing equipment. Background Technology

[0002] Liquid crystal displays (LCDs) are a widely used flat-panel display technology that utilizes the optical properties of liquid crystal materials under the influence of an electric field to display images. LCDs offer advantages such as small size, light weight, low power consumption, high resolution, and rich colors, and are widely used in various consumer electronics products such as televisions, computer monitors, smartphones, tablets, and digital cameras. The core of an LCD is the liquid crystal molecule, sandwiched between two transparent conductive glass plates coated with transparent electrodes and an alignment layer. When no external electric field is applied, the liquid crystal molecules align according to the orientation of the alignment layer. When a voltage is applied, the liquid crystal molecules rearrange, thereby changing the polarization direction of the light passing through the liquid crystal layer. LCDs are typically used in conjunction with a backlight. The light emitted from the backlight is modulated by the liquid crystal layer, and different colors and brightness are displayed by controlling the amount of light transmitted through each pixel.

[0003] With the continuous development of LCD technology, consumers have increasingly higher requirements for the resolution, thickness, lightweight, and appearance of display devices. The assembly process of LCD modules is also becoming more and more refined. In the manufacturing process of LCD screens, the bonding process is one of the key links, and its quality directly affects the display effect and service life of the final product. At present, in the bonding process of LCD screens, manual placement and alignment or semi-automatic bonding methods are usually used. However, traditional bonding equipment lacks an effective positioning structure, which is prone to misalignment due to human error or mechanical deviation. Furthermore, when bonding multiple layers of materials, existing equipment requires multiple adjustments to the position, which is cumbersome and affects production efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that during the current bonding process of LCD screens, misalignment is easily caused by human error or mechanical deviation. When bonding multiple layers of materials, multiple adjustments to the position are required, which is cumbersome and affects production efficiency.

[0005] To solve the above problems, the present invention proposes the following technical solution: a bonding device for processing liquid crystal displays with auxiliary alignment function, including a worktable; an adsorption component capable of adjusting the position is provided on the upper part of the worktable, and an adjustment component for adjusting the position of the workpiece is provided in the middle part of the worktable.

[0006] As an improvement, the workbench includes a base plate, legs set at the four corners of the lower end of the base plate, support rods set at the four corners of the upper end of the base plate, and a top plate set at the upper end of the support rods.

[0007] As an improvement, the adsorption assembly includes a cylinder 1 located at the middle of the lower end of the top plate, a triple rotating component located at the lower end of the cylinder, and a suction cup located at the lower end of the triple rotating component.

[0008] As an improvement, the three rotating components include rotating rod one, rotating rod two, and rotating rod three that are sequentially hinged in a stepped manner.

[0009] As an improvement, the adjustment assembly includes a plurality of cylinders 2 arranged around the upper part of the base plate, a movable rod that is elastically telescopically arranged in the piston rod of the cylinder 2 by springs, a guide plate arranged on both sides of the piston rod of the cylinder 2, an adjustment plate arranged at the end of the movable rod, and a guide rod arranged on both sides of one end of the adjustment plate and passing through the guide plate.

[0010] As an improvement, the lower end of the guide plate is attached to the upper surface of the base plate, the guide plate is located outside the suction cup, and the guide rod is located outside the second cylinder.

[0011] The beneficial effects of this utility model are:

[0012] By setting an adjustable adsorption component on the upper part of the worktable and an adjustment component in the middle of the worktable to adjust the position of the workpiece, the device allows for easy operation. When two workpieces are placed on the worktable and adsorbed onto the adsorption component, the adsorption component is lowered so that the two workpieces are positioned within the adjustment component. Activating the adjustment component then aligns the sides of the two workpieces, preventing misalignment during bonding. Furthermore, when bonding multiple layers of material, only sequential bonding is required, eliminating the need for multiple position adjustments and simplifying operation.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] according to Figure 1 —3 shows: This utility model provides a bonding device for processing liquid crystal displays with auxiliary alignment function: including a worktable 1; the worktable 1 includes a base plate 101, support legs 102 set at the four corners of the lower end of the base plate 101, support rods 103 set at the four corners of the upper end of the base plate 101, and a top plate 104 set at the upper end of the support rods 103; this is the basic structure of a commonly used worktable 1.

[0019] according to Figure 1 , 2 As shown: The upper part of the workbench 1 is equipped with an adjustable adsorption assembly 2; the adsorption assembly 2 includes a cylinder 201 located in the middle of the lower end of the top plate 104, a triple rotating component 202 located at the lower end of the cylinder 201, and a suction cup 203 located at the lower end of the triple rotating component 202; the triple rotating component 202 includes a rotating rod 1, a rotating rod 2, and a rotating rod 3 that are hinged in a stepped manner; in this way, a workpiece can be adsorbed by the suction cup 203, and then the cylinder 201 can drive the workpiece to rise or fall, and the triple rotating component 202 can passively change the relative position of the workpiece.

[0020] according to Figure 1 , 3 As shown: The worktable 1 is provided with an adjustment assembly 3 for adjusting the position of the workpiece in the middle. The adjustment assembly 3 includes several cylinders 301 arranged around the upper end of the base plate 101, movable rods 303 elastically telescopically arranged in the piston rods of the cylinders 301 by springs 302, guide plates 304 arranged on both sides of the piston rods of the cylinders 301, adjustment plates 305 arranged at the ends of the movable rods 303, and guide rods 306 arranged on both sides of one end of the adjustment plate 305 and passing through the guide plates 304. The lower end of the guide plate 304 is attached to the upper end surface of the base plate 101, and the guide plate 304 is located outside the suction cup 203. The guide rod 306 is located outside the cylinder 301. After the suction cup 203 picks up one workpiece and another workpiece is placed on the bottom plate 101, the suction cup 203 is lowered so that neither workpiece is higher than the upper end of the adjusting plate 305. At the same time, the cylinder 301 is activated, which allows the adjusting plate 305 to fit against the side of the workpiece, thereby adjusting the relative position of the two workpieces. Then, after the workpiece on the suction cup 203 is lowered, the two workpieces can fit together. The design of the spring 302 and the moving rod 303 allows the adjusting plate 305 to adjust and fix the position of the workpiece without damaging it.

[0021] The principle of this utility model is as follows: In use, the workpiece that the display screen needs to be attached to is first adsorbed under the suction cup 203. Then, the other workpiece that the display screen needs to be attached to is placed on the base plate 101. Next, glue is applied. Then, the upper workpiece is lowered so that neither workpiece is higher than the upper end of the adjustment plate 305. Then, the cylinder 2 301 is activated at the same time, so that the adjustment plate 305 is attached to the side of the workpiece and the spring 302 is contracted by one end and then returns to normal. During this process, the lower workpiece will be pushed to adjust its position. The upper workpiece can also be pushed because the rotating rods 1, 2 and 3 of the three rotating parts 202 are hinged in a stepped manner. Then, the suction cup 203 is lowered again, and the two workpieces are attached together. The workpieces attached together will not be misaligned.

[0022] When bonding multiple layers of materials, simply follow the steps outlined above.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
