[0002] LCD screen is also called monitor. Monitor is an I / O device of computer, that is, input and output device. It is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye.

[0003] In the process of LCD screen production, it is necessary to apply glue to the inner side of the frame. The existing gluing method is mostly adopted. This method causes excessive glue in some positions during the subsequent installation of the screen, resulting in glue overflowing on the screen to form a glue pad, affecting the aesthetics of the LCD screen. In addition, since the frame is a square frame when the frame is glued in the prior art, it is not easy to clamp the frame limit, so that the frame may be offset during the subsequent gluing, resulting in inaccurate gluing position. Therefore, it is necessary to design a frame gluing device for LCD screen production to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a frame gluing device for liquid crystal screen production, which can simultaneously apply glue to two opposite inner walls of the frame and can smooth the applied glue, so that excessive glue at a certain position will not cause glue spots to be formed on the subsequent screen, and through the setting of the first motor, the suction cup and the limiting plate, not only can the frame be limited, but the frame can also be automatically rotated to apply glue to the other two surfaces.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] Preferably, adjacent sides of the two side plates are fixedly connected with a plurality of pneumatic rods, and telescopic ends of the plurality of pneumatic rods are fixedly connected with corresponding movable plates.

[0011] Preferably, a plurality of lifting rods are fixedly connected to the upper end of the workbench, and the telescopic ends of every two matched lifting rods are commonly fixedly connected to a limiting plate.

[0012] Compared with the existing technology, the advantages of this device are:

[0013] 1. Compared with the prior art, the suction cup and the limiting plate are arranged so that the suction cup can adsorb the back cover of the frame, and the center line of the frame is aligned with the center line of the placement table, so as to ensure that the glue can be accurately distributed on the inner wall of the frame when applying glue;

The lower ends of the two moving blocks 10 are fixedly connected to the nozzle 12, and the two nozzles 12 are connected with a material pipe 13. During processing, an external feeder is provided, and the feeding end of the feeder is connected to the material pipe 13, so that the glue is fed into the nozzle 12 during processing, and then sprayed on the inner wall of the frame through the nozzle 12. The material pipe 13 is a hose, and the lower ends of the two moving blocks 10 are connected to two smoothing rollers 11 for rotation together. A second motor 14 is installed on the fixed body at the rear side, and the end of the output shaft of the second motor 14 is fixedly connected to the corresponding screw rod 5.

[0021] A first motor 16 is installed at the lower end of the workbench 1 , and the end of the output shaft of the first motor 16 is fixedly connected to the electric telescopic rod 15 .

[0022] Among them, a plurality of suction cups 7 are fixedly connected to the upper end of the placement table 6 .

[0023] Among them, a plurality of lifting rods 8 are fixedly connected to the upper end of the workbench 1, and the telescopic ends of every two matching lifting rods 8 are fixedly connected to the limiting plate 9 together, so that after the frame is placed, the center line of the frame is aligned with the center line of the placement platform 6 (before placement, the back cover needs to be installed on the frame, and the back cover is in contact with multiple suction cups 7).

[0024] The functional principle of the utility model can be explained through the following operation mode: first, the back cover of the display is installed on the frame, and then the frame is placed on the four suction cups 7, at which time the four side outer walls of the frame are in contact with the corresponding limit plates 9, and then the frame is pressed downward with force, so that under the action of negative pressure, the suction cups 7 are adsorbed on the back cover, and at this time, the multiple lifting rods 8 are controlled to move downward, so that the limit plates 9 move to the bottom of the frame;

[0025] At this time, the electric telescopic rod 15 is controlled to stretch, so that the frame moves up, so that the nozzle 12 is aligned with the inner walls on the left and right sides of the frame, and the feeder is controlled to run. At the same time, the two second motors 14 are in a running state, so that the moving block 10 drives the nozzle 12 and the two smoothing rollers 11 to move back and forth, so that the nozzle 12 sprays glue on the inner wall of the frame. Since the two smoothing rollers 11 are attached to the inner wall of the frame, the smoothing rollers 11 can evenly spread the glue adhered to the inner wall (in the process of the moving block 10 moving back and forth multiple times, glue will adhere to the smoothing roller 11, so that the position of the inner wall of the frame that the nozzle 12 cannot spray will also be smeared with glue);

[0026] When the coating of the two opposite surfaces is completed, the electric telescopic rod 15 is controlled to retract, and then the first motor 16 is controlled to operate, so that the placement table 6 drives the frame to rotate ninety degrees, and then the multiple pneumatic rods 3 are controlled to stretch, so that the nozzle 12 and the smoothing roller 11 move to the top of the frame, and then the electric telescopic rod 15 is controlled to stretch, so that the frame moves up, and then the multiple smoothing rollers 11 contact the inner wall of the frame again, and the other two inner walls of the frame are coated with glue.
