Description

Technical Field

[0001] The utility model relates to the technical field of LCD display screen processing, in particular to a glue dispensing device for an LCD display screen. Background Art

[0002] The structure of LCD display screen is to place liquid crystal box between two parallel glass substrates, set thin film transistor on the lower substrate glass, set color filter on the upper substrate glass, and control the rotation direction of liquid crystal molecules by changing the signal and voltage on TFT, so as to control whether polarized light of each pixel is emitted or not to achieve the display purpose. In the production process of LCD display screen, it is necessary to dispense glue on its surface for subsequent assembly and bonding.

[0003] At present, most LCD display screen glue dispensing devices are operated by one person, and a single machine can only perform glue dispensing operations on a single workpiece, resulting in high personnel costs, low single machine utilization, and low production capacity. At the same time, in the existing LCD display screen glue dispensing device, the LCD display screen is clamped and transported to the dispensing operation process. Due to the different fits between the clamp and different LCD screens, it is easy for the clamp to be over-clamped or shaken during transportation, causing local wear of the LCD screen, and the position of the LCD screen may also be offset due to shaking, affecting subsequent glue dispensing operations.

The glue dispensing platform is provided with two empty slots, and the first workpiece table and the second workpiece table provided on the tooling table are mounted in the two empty slots.

[0006] Wherein, the first motion slide and the second motion slide are three-axis motion slides.

[0007] Preferably, the first moving slide and the second moving slide share the same Y-axis transmission rod.

[0008] Preferably, the first glue dispensing device and the second glue dispensing device are installed facing each other.

[0009] Furthermore, the first glue dispensing device and the second glue dispensing device include: a glue dispensing gun, a glue tank, a material delivery pipe, and a sensor. The sensor is installed at the front end of the glue dispensing gun, and the glue dispensing gun is connected to the glue tank through the material delivery pipe.

[0010] Furthermore, the tooling table further includes: a rotating spindle and a rotating motor, and the first workpiece table and the second workpiece table are connected to the rotating motor via the rotating spindle.

[0011] The first workpiece platform and the second workpiece platform are in the shape of a square frame with a hollow middle, and are also provided with workpiece platform grooves.

[0012] Furthermore, two barrier ribs are arranged on the dispensing platform.

[0013] After adopting the above technical solution, the utility model has the following effects:

[0014] The utility model realizes simultaneous glue dispensing on two LCD screens by setting two glue dispensing devices, thereby improving work efficiency. The work table of the utility model adopts a rotating method to turn over the LCD screen that needs glue dispensing, and completes the glue dispensing operation on both sides of the LCD screen at one time, thereby improving work efficiency. At the same time, the work table adopts a detachable installation method. For LCD screens of different sizes, the glue dispensing needs of LCD screens of different sizes can be met by replacing the work table.
