[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6This utility model provides a technical solution: a dispensing device for processing height-adjustable liquid crystal display modules, including a base 1, a side support plate 2, a support bracket 3, a glue gun 4, a support platform 5, a working plate 6, a support groove 7, a connecting plate 8, a support rod 9, an electric push rod 10, a lower cylinder 11, an upper cylinder 12, a locking block 13, a screw 14, a connecting block 15, a motor 16, and an air guide cylinder 17.

[0029] Two side support plates 2 are symmetrically arranged on the upper surface of the base 1. The side support plates 2 are L-shaped, and a support frame 3 is fixedly installed on the surface of the side support plates 2. The support frame 3 is a hollow square structure. A glue gun 4 is arranged on the inner surface of the support frame 3. The glue gun 4 is connected to the support frame 3 through a CNC track. The glue gun 4 is connected to a glue supply mechanism through a hose. Two sets of support frames 3 and glue guns 4 are symmetrically arranged. A workpiece support structure is arranged below the glue gun 4. The workpiece support structure supports the liquid crystal display module through a support platform 5 and a work plate 6. The workpiece support structure includes a support platform 5, which is a concave circular plate. Below the glue gun 4, a working plate 6 is rotatably connected to the upper surface of the support platform 5. The working plate 6 has a circular structure and a circular support groove 7 is provided on the upper surface of the working plate 6. There are 4 support grooves 7 arranged in a ring on the upper surface of the working plate 6. A connecting plate 8 is provided below the support platform 5. The connecting plate 8 has a circular structure and is rotatably installed on the upper surface of the base 1. The lower surface of the support platform 5 and the upper surface of the connecting plate 8 are connected by a support rod 9. The support rod 9 has a telescopic structure. An electric push rod 10 is fixedly installed on the upper surface of the base 1. The output end of the electric push rod 10 is fixedly connected to the lower surface of the support platform 5.

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, the electric push rod 10 is activated, lowering the support platform 5 to a suitable height for placing the LCD module. The LCD module is then placed in the support groove 7 on the upper surface of the work plate 6. Multiple workpieces are placed simultaneously in the annular support groove 7. After placement, the electric push rod 10 is activated again, raising the support platform 5 to deliver the workpiece to the appropriate dispensing height. The glue supply mechanism is then activated, allowing glue to flow into the glue gun 4 through the hose. The movement path of the glue gun 4 is controlled by a CNC track to perform the dispensing operation on the LCD module. Because the device is equipped with two symmetrical sets of support frames 3 and glue guns 4, it can dispense glue onto two LCD modules simultaneously, improving dispensing efficiency.

[0031] The working plate 6 is hollow inside. The inner wall of the support groove 7 on the surface of the working plate 6 is provided with a circular through hole that communicates with the inside of the working plate 6. The inner surface of the working plate 6 is connected to the inside of the lower cylinder 11 through a pipe. The lower cylinder 11 is hollow inside. The locking block 13 on the surface of the lower cylinder 11 is a cylindrical structure that is open from top to bottom. The upper end of the locking block 13 is inserted into the inside of the air guide cylinder 17. The air guide cylinder 17 is a hollow ring structure with an open lower surface. The air guide cylinder 17 is rotatably mounted on the upper surface of the upper cylinder 12. The surface of the air guide cylinder 17 is connected to a negative pressure device through a pipe.

[0032] like Figure 2 , Figure 3 and Figure 6 As shown, during the operation of the device, the pipe on the surface of the air guide cylinder 17 is connected to the negative pressure device. The negative pressure device generates negative pressure in the air guide cylinder 17 through the pipe. Since the air guide cylinder 17 is connected to the upper end of the clamping block 13, and the lower end of the clamping block 13 is inserted into the groove on the surface of the lower cylinder 11, the clamping block 13 is connected to the lower cylinder 11. The lower cylinder 11 is connected to the hollow working plate 6 through the pipe. Therefore, the negative pressure device will eventually form negative pressure on the circular through hole surface of the inner wall of the support groove 7 on the surface of the working plate 6, so that the liquid crystal display module is adsorbed at the bottom of the support groove 7, avoiding workpiece displacement during the dispensing process.

[0033] The inner surface of the working plate 6 is provided with a rotating structure. The rotating structure drives the working plate 6 to rotate through the lower cylinder 11, thereby realizing the position adjustment of the workpiece. The rotating structure includes the lower cylinder 11. The outer surface of the lower cylinder 11 is fixedly connected to the inner surface of the working plate 6. The lower surface of the lower cylinder 11 is rotatably mounted on the upper surface of the support platform 5. The upper surface of the lower cylinder 11 is provided with four cylindrical slots in a ring. The bottom of the cylindrical slots on the surface of the lower cylinder 11 is connected to the interior of the lower cylinder 11. The inner wall of the cylindrical slots on the surface of the lower cylinder 11 is fitted with a locking block 13. The locking block 13 is embedded and fixed inside the upper cylinder 12. The upper surface of the upper cylinder 12 is fixed to the lower end of the screw 14. The screw 14 is threadedly connected to the connecting block 15. The connecting block 15 is fixed to the output end of the motor 16 through the connecting rod. The motor 16 is mounted and fixed above the side support plate 2 through the bracket.

[0034] like Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, when the electric push rod 10 drives the support platform 5 to rise, the support platform 5 drives the lower cylinder 11 on the upper surface to move upward and approach the upper cylinder 12. The cylindrical groove on the surface of the lower cylinder 11 engages with the locking block 13 on the lower surface of the upper cylinder 12. At this time, the motor 16 is started, and the motor 16 drives the connecting block 15 to rotate. The connecting block 15 drives the screw 14 and the upper cylinder 12 to rotate. The upper cylinder 12 and the locking block 13 drive the lower cylinder 11 to rotate. The lower cylinder 11 drives the working plate 6 to rotate, adjusting the workpiece to the dispensing position. Rotating the screw 14 causes the screw 14 to move on the surface of the connecting block 15, thereby realizing the height adjustment of the screw 14. The height adjustment of the upper cylinder 12 can be achieved by adjusting the height of the lower cylinder 11, thus adjusting the height that the device can be raised to, making it easier for the device to adapt to the processing of different workpieces.

[0035] Working principle: When using this height-adjustable dispensing device for LCD module processing, the workpiece is placed in the support groove 7 on the upper surface of the work plate 6. The electric push rod 10 is started, which drives the support platform 5 to rise. The support platform 5 drives the lower cylinder 11 to engage with the locking block 13. At this time, the negative pressure device forms a negative pressure on the surface of the support groove 7 through the air guide cylinder 17, the locking block 13, and the lower cylinder 11, adsorbing the LCD module at the bottom of the support groove 7 and preventing the workpiece from shifting. The motor 16 is started, which drives the connecting block 15 to rotate. The connecting block 15 screw 14 and the upper cylinder 12 rotate. The locking block 13 on the lower surface of the upper cylinder 12 drives the lower cylinder 11 to rotate. The lower cylinder 11 drives the work plate 6 to rotate, so that the workpiece is aligned with the glue gun 4. The glue gun 4 is used to dispense glue onto the LCD module, increasing the overall practicality.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
