[0058] The transmission mechanism 1 2, the transmission mechanism 2 3 and the transmission mechanism 3 4 form a complete work assembly line.

[0059] It should be noted that the present invention is an automatic backsheet assembly device for photovoltaic modules. Before use, the device is placed in a desired location. In the initial state, the two suction cup mechanisms 8 are respectively located above the transmission mechanism 1 2 and the transmission mechanism 3 4. The upper backsheet material is placed on the transmission mechanism 1 2 to be transported to a predetermined area, and the lower backsheet material coated with adhesive is placed on the transmission mechanism 2 3 to be transported to a predetermined area, so that it can reach the working operating conditions.

[0060] The motor 25 located above the transmission mechanism 1 2 is started, and it acts on the transmission gear member 1 23 to mesh with the transmission gear member 2 26, so that the movable plate 22 rotates 90 degrees and then stops. Then, the electric telescopic rod 2 39 acts on the suction cup mechanism 8 to move down to a predetermined position and then stops. The suction cup mechanism 8 acts on the movable plate 22 to move down through the first telescopic rod 20, and then the motor 15 is started, so that the two sliders 16 bring the two push plates 28 to move toward the upper backboard material, so that the backboard material on the transmission mechanism 2 is calibrated. The motor 15 moves the two sliders 16 toward the two ends of the bidirectional screw rod 14, and then the electric telescopic rod 2 39 acts on the suction cup mechanism 8 to continue to move downward until the upper backboard material at the corresponding position is adsorbed, and then the suction cup mechanism 8 is lifted. At this time, the upper backboard material is adsorbed, and the motor 4 43 is started to act on the gear plate 44 to mesh with the gear ring 45, so that the storage plate 7 rotates ninety degrees and then stops. At this time, the suction cup mechanism 8 adsorbing the upper backboard material is located above the transmission mechanism 2 3;

[0061] Then, the electric telescopic rod 1 30 is started to carry the lower backboard material on the transmission mechanism 2 3 up to the predetermined position and then stop, and then the position of the two sliders 16 is adjusted by the motor 2 25 to act on the push plate 28 to correct the position of the lower backboard material, and then the motor 3 33 is started to make the two sliders 2 34 move toward the lower backboard material and correct it, and then the position of the two sliders 16 is adjusted by the motor 2 25 to keep it away from the lower backboard material, and then the suction cup mechanism 8 is pressed down with the upper backboard material by the electric telescopic rod 2 39 until the upper backboard material is aligned with the lower backboard material coated with adhesive, and the pressure generated by the downward pressure of the suction cup mechanism 8 is relieved by the spring 2 38 and the second telescopic rod 36, and the lower backboard material is damaged;

[0062] After the sheets are closed, the electric telescopic rod 30 moves down to the initial position, and then the position of the slider 16 is adjusted by the motor 15, and then the movable plate 22 is rotated 90 degrees by the motor 25.

[0063] Then, the motor four 43 is used to make the storage plate 7 continue to rotate ninety degrees. At this time, the suction cup mechanism 8 that has adsorbed the upper backboard material and the lower backboard material after the assembly is located above the transmission mechanism three 4, and the suction cup mechanism 8 that has not adsorbed is located above the transmission mechanism one 2. At this time, the height of the suction cup mechanism 8 is adjusted by the electric telescopic rod two 39, and then the suction cup mechanism 8 that has not adsorbed material repeats the above-mentioned correction and adsorption work on the upper backboard material on the transmission mechanism one 2, and the suction cup mechanism 8 that has adsorbed the upper backboard material and the lower backboard material after the assembly continues to unload the material, so that the assembled upper backboard material and the lower backboard material are unloaded on the transmission mechanism three 4.
