Description

Technical Field

[0001] The utility model relates to the technical field of material conveying of laminating machines, in particular to a conveying device for a laminating machine. Background Art

[0002] With the development of society, screens are widely used in our daily life and are an essential part of our life. However, the screen is mostly made of glass material and is extremely easy to break. Therefore, a protective outer film needs to be pasted on the screen. Currently, a laminating machine is used for lamination. During the process of putting the liquid crystal screen and the protective film into the laminating machine, it needs to be manually put in, with low efficiency. At the same time, because the hand needs to contact the preliminarily laminated screen during the putting-in process, fingerprints will be left on the protective film, affecting the beauty of the screen.

[0003] In the prior art, the existing material feeding and conveying device for a laminating machine has an insufficiently comprehensive use function, is prone to occur the phenomenon of missed conveying, has low feeding efficiency, and is not convenient for the convenient conveying of the material to be pasted. Therefore, a conveying device for a laminating machine is proposed.

[0004] A material feeding and conveying device for a laminating machine disclosed in the publication number CN210793812U. Although, the material feeding and conveying device for the laminating machine includes a loading table for loading the material to be pasted, a manipulator for handling the material to be pasted, and a control system; the manipulator includes a vertical rotating support arm, a horizontal telescopic arm, a rotating motor, a vertical telescopic arm, and a vacuum generator for the taking device; the bottom end of the vertical rotating support arm is in transmission connection with the power output end of the rotating motor, and the top end is movably connected to the horizontal telescopic arm through a first adapter; one end of the horizontal telescopic arm is sleeved on the first adapter and connected to the vertical rotating support arm, and the other end is movably connected to the vertical telescopic arm through a second adapter; one end of the vertical telescopic arm is movably connected to the horizontal telescopic arm, and the other end is fixedly connected to the taking device; the vacuum generator is connected to the taking device through a suction pipe.

[0005] Although the above patent can effectively avoid the screen from being crushed by using a suction material plate made of rubber material instead of a manipulator made of steel material; the material to be pasted can be lifted by the suction cup without leaving marks on the material to be pasted; the vertical telescopic arm is controlled to expand and contract by a steel wire rope and a motor, so that the manipulator can extend into the feeding port of the laminating machine to put the material to be pasted; using the manipulator to replace manual operation has higher work efficiency; however, the device lacks an automatic feeding mechanism, and it is necessary to manually carry the liquid crystal screen made of glass material onto the loading table, and then use the suction cup and the robotic arm to cooperate for secondary conveying, resulting in a relatively high labor cost.

[0006] Therefore, it is very necessary to invent a conveying device for a laminating machine to solve the above problems. Utility Model Content

[0019] 1. For this conveying device for a laminating machine, through the setting of the limiting mechanism and the inspection mechanism, when in use, the power is turned on, and the controller controls the electric push rod on one side to start.
