The LCD back glue machine of the embodiment of the application is implemented by firstly enabling a workpiece carrier 3 to be in a waiting state in a transfer area 21 in the production and processing process, then enabling a pipeline conveying mechanism 7 to convey the workpiece which has completed the previous step to the workpiece carrier 3 to complete a feeding step, then enabling the workpiece carrier 3 to be conveyed to a bonding area 23 through a carrier conveying mechanism 4, enabling back glue 1 to be bonded at a corresponding position of the workpiece through a back glue bonding mechanism 8 to complete a bonding step, then enabling the workpiece carrier 3 to be conveyed to a glue tearing area 22 through the carrier conveying mechanism 4, enabling a piece of oil paper 12 on the workpiece to be torn out through a glue tearing mechanism 9 to complete a glue tearing step, then enabling the workpiece carrier 3 to be conveyed to the transfer area 21 again through the carrier conveying mechanism 4, enabling the workpiece to be conveyed to an operation station of the next step through the pipeline conveying mechanism 7 to complete a discharging step, and enabling the workpiece carrier 3 to be in the waiting state again. The LCD gum machine can automatically paste the gum 1 on the surface of a workpiece, and the oil paper 12 of the gum 1 is automatically torn through the gum tearing mechanism 9, so that the steps of manually pasting the gum 1 and manually tearing the oil paper 12 are omitted, the labor cost is reduced, and the production efficiency is improved.
The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
