[0014] Further, the film pasting assembly comprises two unwinding rollers, and the two unwinding rollers are arranged adjacent to each other and the unwinding paths are parallel.

[0015] In the above technical solution, by arranging two unwinding rollers, the film can be pasted on two parallel edges of the product at the same time, thereby adapting to the film pasting demand of the product and improving the film pasting efficiency.

[0016] Further, a second cutting unit is arranged opposite to the first cutting unit, and the first cutting unit and the second cutting unit are respectively located at two ends of the positioning groove.

[0017] In the above technical solution, the second cutting unit can cut the excess end of the protective film, thereby ensuring the consistency of the pasting of the protective film.

[0018] Further, at least one side of the positioning groove is provided with a plurality of taking and placing grooves.

[0019] In the above technical solution, the taking and placing grooves provide space for the hands of the operators to extend into the positioning seat, facilitating the taking and placing of the product, and making the operation more convenient.

[0020] Compared with the prior art, the backlight module to be pasted with the film can be positioned by the positioning groove, and the stability of the backlight module during film pasting is ensured. The unwinding roller of the film pasting assembly can unwind the protective film. After the protective film is limited by the guide roller, the protective film corresponds to the film pasting position of the backlight module. The operator only needs to lengthen the protective film and paste it, and the protective film and the backlight module do not need to be aligned. On the one hand, the accuracy of film pasting is ensured, and on the other hand, the efficiency of film pasting is improved. After the protective film is pasted, the protective film pasted on the backlight module can be separated by the first cutting unit, so that the film pasting is completed. The overall structure is simple, convenient to operate, and the film pasting efficiency and quality are effectively improved. BRIEF DESCRIPTION OF DRAWINGS
