Description

Technical Field

[0001] The utility model belongs to the technical field of LCD production, and specifically relates to a dispensing device for LCD production. Background Art

[0002] A liquid crystal display (LCD) is a type of display used in digital clocks and many portable computers. The LCD display uses two pieces of polarized material, and between them is a liquid crystal solution. When an electric current passes through the liquid, the crystals will rearrange so that light cannot pass through them.

[0003] After retrieval, CN210647095U discloses a dispensing device for LCD production, including a base. Electric telescopic rods are bolted to the four corners of the outer wall of the top of the base, and a top plate is arranged at the piston end of the electric telescopic rod. A glue storage tank is arranged on the outer wall of the top of the top plate, and a glue adding pipe is arranged on the outer wall of the top of the glue storage tank. A sealing cover is threadedly connected to the inner wall of the glue adding pipe. A gas guide pipe is arranged on the outer wall of the top of the glue storage tank, and a control valve is bolted to the outer wall of the top of the gas guide pipe. A first electric slide rail is bolted to the outer wall of the bottom of the top plate, and a first slider is slidably connected to the inner wall of the first electric slide rail. A vertical rod is arranged on the outer wall of the bottom of the first slider, and a second electric slide rail is bolted to the outer wall of the bottom of the vertical rod.

[0004] However, through the exploration of the inventor, it is found that the above technical solution still has at least the following defects: in the above device, by setting the first electric slide rail, the second electric slide rail, the glue guide pipe, the hose and the dispensing needle, driving the first electric slide rail to work can drive the dispensing needle to move to a suitable position, and then driving the second electric slide rail to work can drive the second slider to move, so that the dispensing needle can be aligned with the position on the LCD that needs to be dispensed. During the process of aligning the dispensing needle with the dispensing position on the LCD, the dispensing needle needs to be moved frequently, and the alignment process is too complicated. After alignment, the electric telescopic rod works to make the dispensing needle contact the LCD to complete dispensing. However, the dispensing needle is far from the placement seat for placing the LCD, and it is difficult to lower the dispensing needle to contact the LCD.

[0005] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

An activity groove 2 is opened on the top of the substrate 1. The support seat 3 is slidably arranged on the inner wall of the activity groove 2. A placement plate 4 is fixedly installed on the top of the support seat 3. Symmetrically arranged limiting plates 15 are slidably installed on the top of the placement plate 4. On one side of the top of the substrate 1, symmetrically arranged support rods 6 are fixedly connected. On the opposite sides of the two support rods 6, the same mounting plate 7 is fixedly connected. On the left side of the mounting plate 7, a lifting track 9 is fixedly arranged. A guiding plate 10 is slidably arranged in the inner wall of the lifting track 9. The bottom outer wall of the guiding plate 10 is fixedly connected with a mounting rod 11. The bottom end of the mounting rod 11 is hingedly provided with a guiding rod 12. On one outer wall of the support seat 3, a connecting frame 13 is fixedly connected. One end of the guiding rod 12 is hingedly arranged on the connecting frame 13. On one outer wall of the top of the substrate 1, a first cylinder 14 is fixedly installed. The piston rod of the first cylinder 14 is connected to the bottom outer wall of the guiding plate 10. On the right side of the mounting plate 7, a glue storage tank 8 and a glue guiding pipe 16 are fixedly arranged. The glue guiding pipe 16 and the glue storage tank 8 are connected and communicated through a pipeline. At the bottom of the glue guiding pipe 16, equally spaced dispensing needles 27 are installed. Control valves 28 are arranged on the dispensing needles 27. After the LCD is positioned, the first cylinder 14 is started to work. The first cylinder 14 cooperates with the arranged lifting track 9 to drive the guiding plate 10 to move upward. The guiding plate 10 drives the mounting rod 11 to move upward. The mounting rod 11 cooperates with the arranged connecting frame 13 to change the inclination angle of the guiding rod 12. When the inclination angle of the guiding rod 12 changes, the arranged connecting frame 13 and the activity groove 2 can drive the support seat 3 to move horizontally, so that the support seat 3 drives the LCD to move below the dispensing needle 27 until the LCD moves below the dispensing needle 27 and the bottom end of the dispensing needle 27 contacts the top of the LCD. Then, the control valve 28 on the dispensing needle 27 is opened, so that the glue stored in the glue storage tank 8 can be transported to the dispensing needle 27 through the glue guiding pipe 16 and be transported to the position on the LCD that needs to be dispensed through the dispensing needle 27, completing the dispensing work on the LCD.

[0028] In a specific embodiment, a lifting plate 18 is slidably arranged inside the support base 3. Symmetrically arranged sliding brackets 19 are fixedly connected to both sides of the lifting plate 18. Rectangular movable openings 26 are symmetrically arranged on both sides of the support base 3.

Guide brackets 21 are fixedly connected to the outer walls of one side of the two limit plates 15. The tops of the two connecting rods 20 are respectively hingedly arranged on the two guide brackets 21. A second air cylinder 22 is fixedly installed on the bottom inner wall of the support base 3. The piston rod of the second air cylinder 22 is connected to the bottom outer wall of the lifting plate 18. When it is necessary to perform glue dispensing work on the LCD, the LCD is placed on the placement plate 4. After the placement is completed, the second air cylinder 22 is started to drive the lifting plate 18 to move downward. The lifting plate 18 drives the two sliding brackets 19 to move downward. The two sliding brackets 19 cooperate with the two guide brackets 21 arranged to change the inclination angles of the two connecting rods 20. When the inclination angles of the two connecting rods 20 change, the two guide brackets 21 arranged in cooperation can drive the two limit plates 15 to move relatively until the opposite sides of the two limit plates 15 are respectively in contact with the outer walls of both sides of the LCD, realizing the clamping and positioning effect on the LCD.

[0029] Furthermore, an installation base 17 is fixedly arranged on the outer wall of one side of the support base 3. An air pump 24 is fixedly installed on the top outer wall of the installation base 17. The air outlet of the air pump 24 is connected to an air delivery pipe 25. The outer wall of one side of the support base 3 is fixedly connected with an L-shaped support frame, and a gas collection box 5 is fixedly arranged at the top of the support frame. The air delivery pipe 25 is communicated with the gas collection box 5. The gas collection box 5 is located on one side of the placement plate 4. A plurality of equally spaced air outlet holes 23 are arranged on the side of the gas collection box 5 close to the placement plate 4. After the LCD is positioned, the air pump 24 is started to work. The air pump 24 conveys gas into the gas collection box 5 through the air delivery pipe 25, so that the gas can be sprayed onto the surface of the LCD through the air outlet holes 23, facilitating the blowing away of the dust on the surface of the LCD and avoiding the influence of the remaining dust at the glue dispensing position on the glue dispensing work. After the glue dispensing work is completed, the air pump 24 is turned on to work. The air pump 24 conveys gas into the gas collection box 5 through the air delivery pipe 25, so that the gas can be sprayed onto the surface of the LCD through the air outlet holes 23. The blown air facilitates the acceleration of the glue drying process.

[0030] The implementation principle of a glue dispensing device for LCD production in this embodiment is as follows:

[0031] When the LCD needs to be dispensed, place the LCD on the placement board 4. After the placement is completed, start the second cylinder 22 to drive the lifting plate 18 to move downward. The lifting plate 18 drives the two sliding brackets 19 to move downward. The two sliding brackets 19 cooperate with the two guiding brackets 21 provided to change the inclination angles of the two connecting rods 20. When the inclination angles of the two connecting rods 20 change, the two guiding brackets 21 provided can drive the two limiting plates 15 to move relatively until the opposite sides of the two limiting plates 15 are respectively in contact with the outer walls on both sides of the LCD, realizing the clamping and positioning function of the LCD. After the LCD is positioned, start the air pump 24 to work. The air pump 24 conveys the gas through the air delivery pipe 25 into the air collecting box 5, so that the gas can be sprayed onto the surface of the LCD through the air outlet holes 23, facilitating the blowing away of the dust on the surface of the LCD, avoiding the influence of dust remaining at the dispensing position on the dispensing work. At the same time, start the first cylinder 14 to work. The first cylinder 14 cooperates with the lifting track 9 provided to drive the guiding plate 10 to move upward. The guiding plate 10 drives the mounting rod 11 to move upward. The mounting rod 11 cooperates with the connecting frame 13 provided to change the inclination angle of the guiding rod 12. When the inclination angle of the guiding rod 12 changes, the connecting frame 13 and the movable groove 2 provided can drive the support base 3 to move horizontally, so that the support base 3 drives the LCD to move downward below the dispensing needle 27 until the LCD moves below the dispensing needle 27 and the bottom end of the dispensing needle 27 is in contact with the top of the LCD. Then, turn off the air pump 24. After the air pump 24 is turned off, open the control valve 28 on the dispensing needle 27, so that the glue stored in the glue storage tank 8 can be conveyed to the dispensing needle 27 through the glue guiding pipe 16 and be dispensed to the position on the LCD where dispensing is required through the dispensing needle 27, completing the dispensing work on the LCD. When the dispensing work is completed, turn on the air pump 24 again to work. The air pump 24 conveys the gas through the air delivery pipe 25 into the air collecting box 5, so that the gas can be sprayed onto the surface of the LCD through the air outlet holes 23, and the blown air facilitates the process of accelerating the drying of the glue.
