Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to an LCM precision dispensing mechanism. Background Technology

[0002] A liquid crystal display module is a modular component that integrates liquid crystal display devices, driving circuits, backlights, polarizers, and control chips into one unit. It can be directly used as a display terminal in various electronic devices and is a key intermediate link in the process of liquid crystal display technology from panel to actual product. Through integrated design, it simplifies the development and production process of OEMs.

[0003] LCM precision dispensing mechanisms are automated equipment components used in the production process of liquid crystal display modules. They precisely apply liquid adhesive to designated locations through precise control. Their core function is to ensure a high degree of consistency in adhesive quantity, position, and shape to meet the stringent precision and reliability requirements of LCM internal chip bonding, panel encapsulation, and component fixing processes. However, in existing LCM precision dispensing mechanisms, when dispensing adhesive around the sidewalls of the LCM, the curved surface structure causes the adhesive to flow easily, resulting in uneven adhesive layer thickness. Uneven adhesive layer can reduce the sealing effect, affect assembly accuracy, and even cause short circuits. To ensure quality, multiple inspections and re-coatings are often required, increasing process time and leading to poor adhesive layer fusion. Utility Model Content

A moving component 207 is fixedly connected to the front side of the outer wall of the moving strip 201. The moving component 207 includes a support frame 2071. The support frame 2071 is fixedly connected to the front side of the outer wall of the moving strip 201. Motors 2072 are fixedly connected to the left and right sides of the outer wall of the support frame 2071. Rollers 2073 are fixedly connected to the output ends of the two motors 2072.

[0032] Specifically, the LCM precision dispensing mechanism completes dispensing through coordinated operation.

Motor 2072 of the moving component 207 drives the roller 2073, which drives the conveyor belt 2074 to rotate. The electric push rod 2075 pushes the moving plate 2076 to realize the left and right movement and positioning of the dispensing head 205. The suction cup 206 helps to fix the material and ensure dispensing accuracy. The lifting mechanism 3 is used to adjust the height of the material.

[0033] Reference Figure 1 , Figure 2 and Figure 5The lifting mechanism 3 includes a protective plate 301, which is fixedly connected to the bottom front side of the fixed frame 1. Multiple baffles 302 are fixedly fixed on the top of the outer wall of the protective plate 301. Limit rods 303 are fixedly connected to the left and right sides of the inner wall of the protective plate 301. A lifting plate 304 is slidably connected to the middle of the inner wall of the protective plate 301. A rotating component 305 is fixedly connected to the rear side of the outer wall of the protective plate 301. The rotating component 305 includes a motor 3051, which is fixedly connected to the rear side of the outer wall of the protective plate 301.

[0034] Specifically, motor 3051 drives lifting mechanism 3, and through the rotation component 305 and belt 3053 transmission system, it realizes the vertical movement of lifting plate 304. Turntable 1 3052 and turntable 2 3054 cooperate to convert the rotational motion into the linear motion of lifting plate 304. Limit rod 303 and baffle 302 ensure the stability and safety of the lifting process. The forward and reverse rotation of motor 3051 controls the movement of lifting plate 304, which is suitable for scenarios where the working position needs to be dynamically adjusted.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The testing mechanism 4 includes a camera 401, which is fixedly connected to the middle of the inner wall of the fixed frame 1. A gasket 402 is fixedly connected to the bottom of the outer wall of the camera 401. A lifting assembly 403 is fixedly connected to one side of the outer wall of the camera 401. The lifting assembly 403 includes a hydraulic push rod 4031, which is fixedly connected to one side of the outer wall of the camera 401. A support plate 4032 is fixedly connected to the right side of the outer wall of the hydraulic push rod 4031. The support plate 4032 is fixedly connected to the middle of the inner wall of the fixed frame 1. A hinge 5 is rotatably connected to the front side of the outer wall of the fixed frame 1. A cabinet door 6 is fixedly connected to one side of the outer wall of the hinge 5. A display screen 7 is fixedly connected to the left side of the middle part of the fixed frame 1. An operating table 8 is slidably connected to the right side of the middle part of the fixed frame 1.

[0036] Specifically, the testing unit 4 uses camera 401 as its core to perform testing tasks. The gasket 402 acts as a buffer and protector to ensure the stable operation of camera 401. The hydraulic push rod 4031 in the lifting assembly 403 works in conjunction with the support plate 4032 to flexibly adjust the height of camera 401 according to testing needs, enabling testing at different angles and distances. During testing, camera 401 acquires images or data information and transmits it to the display screen 7 on the left side of the middle of the fixed frame 1 for display. The operator controls the operation through the operating console 8 on the right side of the middle. The cabinet door 6 is connected to the fixed frame 1 through hinges 5 and can be closed when not in use to protect the internal equipment and facilitate daily maintenance and repair.

[0037] Working principle: This LCM precision dispensing mechanism achieves dispensing function through the coordinated operation of various parts. In the adjustment mechanism 2, motor 1 202 drives the moving wheel 203 to slide on the moving bar 201, so that the robotic arm 204 and the dispensing head 205 can move back and forth. Motor 2072 of the moving component 207 drives the roller 2073, which drives the conveyor belt 2074 to rotate. The electric push rod 2075 pushes the moving plate 2076 to realize the left and right movement and positioning of the dispensing head 205. At the same time, the suction cup 206 can help fix the material to ensure dispensing accuracy. The lifting mechanism 3 is used to lift the processed material and can adjust the material height according to the dispensing requirements. The detection mechanism 4 can detect the material during or after the dispensing process. All the mechanisms cooperate with each other to achieve the precision dispensing work of LCM.

[0038] Motor 3051 is the power source for lifting mechanism 3. It achieves vertical movement of lifting plate 304 via rotating assembly 305. After motor 3051 starts, it drives turntable 3052 at its output end to rotate. Turntable 3052 transmits power to turntable 3054 at the bottom of the inner wall of protective plate 301 via belt 3053, forming a belt 3053 transmission system. This system ensures smooth power transmission and speed regulation. The threaded rod 3055 fixed in the middle of turntable 3054 rotates synchronously with the turntable. The threaded rod 3055 and the lifting plate 304... 04 forms a threaded engagement, converting the rotational motion into the vertical motion of the lifting plate 304. The limiting rods 303 on the left and right sides of the inner wall of the protective plate 301 pass through the lifting plate 304, restricting its movement trajectory and ensuring that it does not deviate during the lifting process. At the same time, the multiple baffles 302 at the top can prevent foreign objects from falling into the mechanism, playing a protective role. The rotation direction of the threaded rod 3055 is controlled by the forward and reverse rotation of the motor 3051, so that the lifting plate 304 slides along the limiting rod 303, realizing the precise adjustment of the preset height and ensuring the accuracy of material conveying.
