Under the action of the spring piece, the splint can adapt to workpieces of different sizes, ensuring positioning accuracy while improving the versatility of the equipment and meeting the diverse needs of gluing operations.

[0023] A gluing process for a precision gluing device for LCD / OLED modules, wherein the specific steps of the gluing process for the precision gluing device for LCD / OLED modules are as follows:

[0024] S1. High-precision displacement assembly realizes precise positioning, which is divided into X-axis and Y-axis displacement drive. In the X-axis drive, after the first transmission motor is started, the rotating shaft drives the first bevel gear to rotate, and transmits the power to the second bevel gear through the meshing transmission of the first bevel gear and the second bevel gear, thereby rotating the spur gear meshing with the rack, and the spur gear rolls on the rack, driving the support plate to make a linear motion along the support block, and the slider slides in the first limit block to provide guidance and precision guarantee for the support plate, thereby realizing high-precision displacement in the X-axis direction. The Y-axis drive relies on the second transmission motor to drive the first transmission wheel to rotate, and transmits the power to the second transmission wheel through the belt. The movable plate fixed on the belt slides along the top of the support seat under the guidance of the second limit block to realize Y-axis displacement. The cooperation of the two can accurately position the gluing assembly to the position to be glued;

[0025] S2, the gluing component is responsible for the glue processing and coating work. The glue is injected into the glue cylinder from the feed port. The third transmission motor drives the spiral blade to stir the glue to prevent the glue from settling and stratification. The heating wire can adjust the glue viscosity as needed to achieve the optimal coating state. When the gluing component is positioned, the cylinder pushes the moving block downward along the third limit block, driving the gluing head close to the module and opening the valve. Driven by the spiral blade, the glue is squeezed out from the gluing head through the connecting pipe, completing the gluing operation according to the preset path. The buckle on the fixed plate fixes the connecting pipe to prevent it from shaking or twisting during movement, ensuring stable glue delivery.

[0026] S3. The positioning component provides support for stable clamping of the workpiece. After the fourth transmission motor is started, it drives the first rotating block to rotate, and the second rotating block converts the rotational motion into linear motion of the connecting block, which in turn drives the movable frame to slide along the guide rod and the second limit slot. The linear motion of the movable frame brings the splint close to the workpiece, and the rubber pad increases the friction to ensure firm clamping. The elasticity of the spring gives the splint a buffering ability to prevent damage to the precision workpiece during clamping, and at the same time enables it to adapt to workpieces of different sizes, thereby improving the versatility of the equipment. The positioning component accurately fixes the workpiece to ensure a stable position of the workpiece during the gluing process, and cooperates with the high-precision displacement component and the gluing component to ensure the accuracy and quality of the gluing. During the entire working process, the high-precision displacement component, the gluing component and the positioning component cooperate with each other, and through precise mechanical transmission and control, the precise gluing of the LCD / OLED module is achieved, meeting the display industry's requirements for high precision, high efficiency and high stability in gluing.

[0027] Compared with the prior art, the advantages and positive effects of the present invention are:

[0028] 1. In the present invention, when working, the support plate on the support block and the movable plate on the support seat are precisely moved under the action of the high-precision displacement component, and the gluing component is positioned to the position to be glued. In the gluing component, the glue enters the glue cylinder from the feed port, and the third transmission motor drives the spiral blade to stir the glue. The heating wire can heat the glue and adjust its viscosity. The cylinder pushes the movable block to drive the glue head to move down close to the module, and the valve is opened. Under the push of the spiral blade, the glue is squeezed out from the glue head through the connecting pipe, and the gluing operation is completed according to the set path. The high-precision displacement component ensures the accuracy of the glue coating position, and the glue coating component realizes operations such as stirring, heating, and extrusion of the glue. The two work together to achieve precise gluing of LCD / OLED modules.

[0029] 2. In the present invention, the rack on the side of the support block meshes with the spur gear on the support plate to form a horizontal drive structure. When the first transmission motor is started, the rotating shaft and the first bevel gear on it rotate. Through the meshing transmission of the first bevel gear and the second bevel gear, the second bevel gear drives the bottom spur gear to rotate, and the spur gear rolls on the rack, driving the support plate to make a linear motion along the support block. The slider is slidably connected to the first limit block to ensure the movement accuracy of the support plate, realize high-precision displacement drive in the X direction, and provide basic positioning function for the gluing operation. The movable plate on the top of the support seat realizes Y-direction displacement through belt transmission, and the second transmission motor drives the first transmission wheel, which drives the second transmission wheel to rotate synchronously through the belt. The movable plate is fixed on the belt and moves accordingly. The second limit block provides a sliding guide for the movable plate to ensure smooth movement, so that the movable plate can quickly respond to control instructions, realize coordinated movement with the horizontal drive, and complete precise positioning of complex gluing paths.

[0030] 3. In the present invention, the fourth transmission motor drives the first rotating block to rotate, and the second rotating block converts the rotational motion into the linear motion of the connecting block, and then drives the movable frame to slide along the guide rod and the second limit groove, so that the rotational motion of the fourth transmission motor is efficiently converted into the linear motion of the movable frame, providing drive for the positioning of the splint, and realizing precise clamping and positioning of the workpiece. The linear motion of the movable frame drives the splint to approach the workpiece, and the rubber pad increases the friction with the workpiece, thereby improving the clamping stability. The elasticity of the spring sheet gives the splint a certain buffering capacity during the clamping process, avoiding damage to the precision workpiece. Under the action of the spring sheet, the splint can adapt to workpieces of different sizes, ensuring positioning accuracy while improving the versatility of the equipment and meeting the diverse needs of gluing operations.

A gluing process for a precision gluing device for LCD / OLED modules, the precision gluing device for LCD / OLED modules according to any one of claims 1 to 8, characterized in that: The specific steps of the LCD / OLED module precision glue coating process are as follows: S1, high-precision displacement assembly (2) realizes precise positioning, which is divided into X-axis direction and Y-axis direction displacement drive. In the X-axis direction drive, after the first transmission motor (24) is started, the rotating shaft (25) drives the first bevel gear (26) to rotate, and the power is transmitted to the second bevel gear (27) through the meshing transmission of the first bevel gear (26) and the second bevel gear (27), thereby rotating the spur gear (28) meshed with the rack (22), and the spur gear (28) rolls on the rack (22), driving the support plate (23) to make a linear motion along the support block (21), and the slider (21) 0) slides in the first limit block (29), provides guidance and precision guarantee for the support plate (23), and realizes high-precision displacement in the X-axis direction. The Y-axis direction is driven by the second transmission motor (212) to drive the first transmission wheel (213) to rotate, and transmits power to the second transmission wheel (215) through the belt (214). The movable plate (217) fixed on the belt (214) slides along the top of the support seat (211) under the guidance of the second limit block (216), realizing displacement in the Y-axis direction. The two cooperate to accurately position the glue coating component (3) to the position to be glued; S2, the glue coating component (3) is responsible for the glue liquid processing and coating work. The glue liquid is injected into the glue cylinder (31) from the feed port (35). The third transmission motor (32) drives the spiral blade (33) to stir the glue liquid to prevent the glue liquid from settling and stratification. The heating wire (34) can adjust the glue liquid viscosity as needed to achieve the best coating state. When the glue coating component (3) is positioned, the cylinder (37) pushes the moving block (38) to move downward along the third limit block (39), driving the glue coating head (310) close to the module and opening the valve (311). Under the push of the spiral blade (33), the glue liquid is squeezed out from the glue coating head (310) through the connecting pipe (312), and the glue coating operation is completed according to the preset path. The buckle (313) on the fixed plate (36) fixes the connecting pipe (312) to prevent it from shaking and twisting during movement, thereby ensuring stable glue liquid delivery; S3 and the positioning assembly (4) provide support for the stable clamping of the workpiece. After the fourth transmission motor (43) is started, it drives the first rotating block (44) to rotate, and the second rotating block (45) converts the rotary motion into the linear motion of the connecting block (46), thereby driving the moving frame (47) to slide along the guide rod (412) and the second limiting groove (48). The linear motion of the moving frame (47) makes the clamping plate (410) close to the workpiece, and the rubber pad (411) increases the friction force to ensure a firm clamping. The elasticity of the spring (49) gives the clamping plate (410) a buffering ability to prevent the clamping The device can adapt to workpieces of different sizes and improve the versatility of the equipment. The positioning component (4) fixes the workpiece accurately to ensure the stability of the workpiece position during the gluing process. The high-precision displacement component (2) and the gluing component (3) are coordinated to ensure the accuracy and quality of the gluing. During the entire working process, the high-precision displacement component (2), the gluing component (3) and the positioning component (4) cooperate with each other. Through precise mechanical transmission and control, the precise gluing of the LCD / OLED module is achieved, meeting the display industry's requirements for high precision, high efficiency and high stability of gluing.
