[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-4 An LED electronic screen dispensing machine is provided. The LED electronic screen dispensing machine includes a frame 1, a worktable 101 on the frame 1, and a vertical plate 102 installed on the top of the worktable 101. The glue dispensing mechanism includes a glue storage tank 2 mounted on the frame 1, a metering glue pump 3 mounted on the glue storage tank 2, a glue dispensing nozzle 6, and a material conveying pipe for connection. The glue dispensing amount is precisely controlled by the metering glue pump 3 to solve the problem of glue overflow or insufficient dispensing caused by fluctuations in the amount of glue dispensed manually, and to ensure the reliability of the seal. The rotating structure includes a turntable 7 rotatably mounted on the workbench 101. The turntable 7 is driven by a servo motor 8. The turntable 7 is located below the dispensing port of the dispensing nozzle 6. The servo motor 8 drives the turntable 7, which can realize continuous operation of multiple workstations. After the LED screen is placed, it automatically rotates to the dispensing position, which greatly reduces manual handling time and improves production efficiency. The fixed structure includes hand-tightening bolts 9 arranged in a circular array and installed on the turntable 7, and a retaining block 10 sleeved and installed on the hand-tightening bolts 9. The hand-tightening bolts 9 and the retaining block 10 cooperate to quickly clamp LED screens of different sizes to meet the needs of flexible production. The PLC controller 11 is installed on the workbench 101 and integrates a human-machine interface 1101. The PLC controller 11 is electrically connected to the metering glue pump 3 and the servo motor 8 via cables. The integrated human-machine interface 1101 on the PLC controller 11 enables digital setting of parameters (such as glue dispensing volume and speed), reduces the operating threshold, and improves the level of automation.

[0020] Reference Figure 1 and Figure 2 The bottom edge of the frame 1 is equipped with a support foot 105, and the support foot 105 has an elongated oval fixing hole 106 for fixing. In application, the design of the elongated oval fixing hole 106 facilitates the installation and leveling of the equipment, enhances working stability, and avoids vibration affecting accuracy during glue dispensing.

[0021] Reference Figure 1 and Figure 2 The material conveying pipeline includes an inlet pipe 4 installed between and connected to the glue storage tank 2 and the metering glue pump 3, and a discharge pipe 5 installed between and connected to the metering glue pump 3 and the glue dispensing nozzle 6. The discharge pipe 5 passes through the vertical plate 102 and its extended portion is connected to the glue dispensing nozzle 6. In application, the inlet pipe 4 and the discharge pipe 5 have a clear division of labor. The discharge pipe 5 is fixed through the vertical plate 102 to reduce glue volume errors caused by pipeline shaking and ensure the stability of the glue dispensing path.

[0022] Reference Figure 1 and Figure 2 The worktable 101 has a clearance slot 103, and the servo motor 8 is installed in the clearance slot 103. One end of the output shaft of the servo motor 8 is fixedly installed on the bottom of the turntable 7. In application, the servo motor 8 is placed in the clearance slot 103, which saves space and protects the servo motor 8 from glue contamination, thus extending the equipment life.

[0023] Reference Figures 2-4 The top of the workbench 101 is provided with an annular groove 104, and the bottom of the turntable 7 has an integrally formed limiting protrusion 701 corresponding to the annular groove 104. The limiting protrusion 701 is adapted to the annular groove 104. The turntable 7 is rotatably mounted on the workbench 101 through the limiting protrusion 701 and the annular groove 104. In application, the limiting protrusion 701 cooperates with the annular groove 104 to ensure the coaxiality of the rotation of the turntable 7 and avoid the deviation of the glue pouring position caused by the sway.

[0024] Reference Figure 2 and Figure 3 The top of the turntable 7 has threaded holes 702 corresponding to the hand-tightening bolts 9, and the threaded holes 702 are threadedly connected to the hand-tightening bolts 9. In application, the hand-tightening bolts 9 are directly screwed into the threaded holes 702, which simplifies the clamping mechanism and reduces maintenance costs.

The horizontal part is sleeved on the hand-tightening bolt 9. The vertical part is made of flexible material. In application, the vertical part is made of flexible material (such as silicone) to avoid damaging the LED screen frame. The horizontal part sleeved on the hand-tightening bolt 9 provides stable pressure, taking into account both protection and fixing strength.

[0026] The working principle of this utility model is as follows: Equipment debugging and initialization: First, adjust the support foot 105 to make the equipment level, and check the glue balance in the glue storage tank 2. Then, input the glue dispensing volume and speed on the human-machine interface 1101, and start the metering glue pump 3 to pre-dispense glue and remove air bubbles from the pipeline. LED screen clamping and glue application: First, place the LED screen on the turntable 7, tighten the hand-tightening bolts 9, and press the frame with the flexible vertical part of the pressure block 10. Then, the PLC controller 11 controls the servo motor 8 to drive the turntable 7 to rotate to the glue application position. At this time, the glue application nozzle 6 is 1-2mm away from the screen body. Finally, the metering glue pump 3 applies glue according to the set amount. After completion, the turntable 7 automatically rotates to the next station, and the glued workpiece can be removed manually. Cleaning and maintenance: After shutdown, clean the dispensing nozzle 6 and the material delivery pipe to prevent the glue from solidifying and clogging. Also check the wear of the limit ring 701 and the annular groove 104, and calibrate the accuracy of the metering glue pump 3.
