Description

TECHNICAL FIELD

[0001] The application relates to the technical field of backlight assembly machines, in particular to a full-automatic backlight assembly machine for mobile phone screen processing and an operation method thereof. BACKGROUND

[0002] In the production and processing of mobile phone screens, a backlight assembly machine is needed to assemble the backlight module and the liquid crystal module. The existing backlight assembly machine comprises a backlight feeding mechanism and a liquid crystal feeding mechanism. The backlight feeding mechanism and the liquid crystal feeding mechanism respectively feed the backlight module and the liquid crystal module to a buffer area, and then the backlight module and the liquid crystal module are fed to a film tearing station by a mechanical arm. The protective film of the liquid crystal module is located at the bottom, and a tape film tearing device is usually used for tearing the film. The liquid crystal module is directly carried to the lamination station by the mechanical arm, and the protective film on the upper surface is torn off by the clamping jaw. Then the liquid crystal module after film tearing is carried to the lamination station for lamination assembly.

[0003] In the film tearing process of the liquid crystal module, there are usually two liquid crystal modules on the stage at the same time. The stage is moved by a linear drive mechanism, and the recovery wheel of the tape drives the liquid crystal module on the tape to move by the driving of the servo motor. Due to the guidance of the front end of the travel direction of the stage, the travel direction of the liquid crystal module driven by the tape is consistent with that of the stage, and until the liquid crystal module located in front and the stage are both moved to the discharge position. At this time, the liquid crystal module is fixed by the suction cup device of the mechanical arm, the stage is returned to the original position, and the stage cooperates with the moving roller at the bottom to make the tape under the liquid crystal module grabbed by the mechanical arm be taken away synchronously, completing the film tearing of a single liquid crystal module. The other liquid crystal module is positioned by the tape, and the stage moves relative to the liquid crystal module until it is reset. The next liquid crystal module is fed from the buffer area, so as to complete the flow film tearing operation in a cycle.

[0004] However, in the existing backlight assembly machine, when the liquid crystal module driven by the tape stops at the discharge position, the liquid crystal module is easily affected by its own inertia and is easy to move relative to the tape, resulting in the phenomenon that the liquid crystal module still slides forward after the tape stops moving. Moreover, the discharge position of the liquid crystal module is usually that the liquid crystal module partially protrudes from the stage, so that the protective film of the protruding part is taken away by the tape, facilitating the subsequent film tearing action, making the inertia deviation of the liquid crystal module more likely to occur, causing the positioning deviation of the liquid crystal module, and directly affecting the lamination precision of the backlight module and the liquid crystal module. Since the beat length of the film tearing action is usually the longest part in the working process of the backlight assembly machine, reducing the linear speed of the tape will cause the beat of the whole backlight assembly machine to slow down, affecting the efficiency of mobile phone screen production. Moreover, the quality of liquid crystal modules of different specifications is not uniform, and it is difficult to uniformly adjust the speed. SUMMARY

[0005] The application provides a full-automatic backlight assembling machine for mobile phone screen processing and an operation method thereof.

[0006] To achieve the above-mentioned purpose, the application adopts the following technical scheme: a full-automatic backlight assembling machine for mobile phone screen processing, comprising a mounting seat, a moving plate movably arranged on one side of the mounting seat, a connecting rod, a loading platform fixedly connected to the top of the connecting rod, a pay-off roller rotatably connected to one side of the mounting seat, an adhesive tape arranged outside the pay-off roller, a driving roller rotatably connected to the other side of the bottom of the mounting seat, a linear driving mechanism fixedly arranged on one side of the back of the mounting seat, an adjusting cylinder fixedly connected to one side of the bottom of the loading platform, a plurality of through holes in a rectangular distribution formed in the top of the loading platform, a sliding plug slidably sleeved in the adjusting cylinder, and a connecting cavity formed in the loading platform, wherein connecting holes for connecting the adjusting cylinder and the connecting cavity are formed in the loading platform and the adjusting cylinder.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Embodiment one, as Figures 1-3 , Figure 5 An automatic backlight assembly machine for processing mobile phone screens comprises a mounting seat 1, the mounting seat 1 is arranged at a film tearing station of a liquid crystal module 13 of the backlight assembly machine, a moving plate 3 is movably arranged on one side of the front of the mounting seat 1, referring to Figure 5 One side of the moving plate 3 is fixedly connected with a connecting rod 34, the connecting rod 34 is slidably connected with the mounting seat 1, the top of the connecting rod 34 is fixedly connected with a carrier 2, the carrier 2 is used for carrying the liquid crystal module 13 and tearing the film by reciprocating movement in cooperation with an adhesive tape 11, one side of the bottom of the mounting seat 1 is rotatably connected with a winding roller 16, the other side of the bottom of the mounting seat 1 is rotatably connected with an active roller 4, one side of the mounting seat 1 is rotatably connected with an unwinding roller 15, the outer side of the unwinding roller 15 is wound with the adhesive tape 11, the adhesive tape 11 is pulled to the winding roller 16 through the top surface of the carrier 2 and the active roller 4, referring to Figure 2 One side of the bottom of the mounting seat 1 is fixedly provided with a No. 2 tensioning motor 25, one side of the mounting seat 1 is fixedly provided with a No. 1 tensioning motor 24, the active roller 4 is used for rotating to drive the body of the adhesive tape 11 to move, and the linear speed of the adhesive tape 11 is controlled.

[0024] The output end of the first tensioning motor 24 is in transmission connection with the unwinding roller 15 through a rotating shaft, and the output end of the second tensioning motor 25 is in transmission connection with the winding roller 16 through a rotating shaft. The first tensioning motor 24 is preferably a servo motor, which is used for controlling the tensioning degree of the adhesive tape 11 between the unwinding roller 15 and the driving roller 4 in the unwinding process. The second tensioning motor 25 is preferably a torque motor, which is used for controlling the tensioning degree of the adhesive tape 11 between the driving roller 4 and the winding roller 16 in the adhesive tape 11 traction process. The adjusting roller 10 is movably arranged at the bottom position of the front surface of the mounting seat 1. The adjusting roller 10 is rotatably arranged on a roller seat, and the roller seat is in sliding connection with the mounting seat 1. The bottom of the mounting seat 1 is fixedly connected with the tensioning spring 26. The tensioning spring 26 is fixedly connected with the roller seat of the adjusting roller 10. The roller seat cooperates with the adjusting roller 10 to slide relative to the mounting seat 1 without being separated from the mounting seat 1. The tensioning spring 26 is used for pushing the adjusting roller 10, so that the adjusting roller 10 abuts against the adhesive tape 11 between the driving roller 4 and the winding roller 16. When the rotating speed of the driving roller 4 increases, the tensioning of the adhesive tape 11 is ensured. In cooperation with the torque motor, the winding roller 16 is driven to tension the adhesive tape 11, so as to avoid the mutual stacking of the adhesive tapes 11 due to the sudden relaxation of the adhesive tapes 11 in the variable speed state, and ensure the stability of the adhesive tape 11 traction process.

The top surface of the carrier 2 is provided with a groove for the adhesive tape 11, and the height of the groove is consistent with the top height of one of the guide rollers 17. After the loading of the liquid crystal module 13 is completed, two liquid crystal modules 13 are stored on the carrier. The moving plate 3 and the carrier 2 move to one side of the mounting seat 1. At this time, the distance between the second moving roller 14 and the guide roller 17 corresponding to the horizontal height is reduced, the carrier 2 is away from the guide roller 17 corresponding to the height, and the distance between the adhesive tapes 11 is increased. The driving roller 4 drives the adhesive tape 11 to rotate, and the linear speed of the adhesive tape 11 is equal to that of the driving roller 4. Since the winding roller 16 winds, the thickness of the adhesive tape 11 is increased due to the winding, so as to avoid the increase of the linear speed due to the increase of the radius of the roller body under the condition of the constant angular speed, which affects the traction speed of the adhesive tape 11.
