Then, through the second electric push rod 9, the connecting plate 8 is moved upward, and through the cooperation of the rack 7 and the gear 102, the positioning column 101 is rotated below the bearing 103. Then, the battery side plate is placed on the placing block 3, and through the second electric push rod 9, the connecting plate 8 is moved downward. At this time, through the cooperation of the rack 7 and the gear 102, the positioning column 101 clamps the battery side plate placed on the placing block 3 and positions the battery side plate. When the battery side plate is positioned, the piston block 53 is moved downward through the first electric push rod 52, and the battery side plate is sucked onto the rubber pad 12 through the piston block 53. At this time, through the suction force and the friction force between the rubber pad 12 and the battery side plate, the battery side plate is fixed on the rubber pad 12. Then, through the second electric push rod 9, the connecting plate 8 is moved upward, and through the cooperation of the rack 7 and the gear 102, the positioning column 101 is rotated below the bearing 103. At this time, the positioning column 101 will not affect the film pasting of the battery side plate. When the film pasting of the battery side plate is completed, the piston block 53 is raised to the initial position through the first electric push rod 52, and the battery side plate can be directly taken away from the rubber pad 12. When checking the suction force of the suction mechanism 5, first, through the third electric push rod 14, the cross plate 18 is made higher than the rubber pad 12. Then, the cross plate 18 is rotated above the rubber pad 12. Then, by pressing the cross plate 18, the cross plate 18 is brought into contact with the rubber pad 12, and the spring 19 is compressed. Then, the piston block 53 is moved downward through the first electric push rod 52. At this time, if the suction force received by the cross plate 18 is greater than the elastic force of the spring 19, the cross plate 18 is sucked onto the rubber pad 12, indicating that the suction force of the suction mechanism 5 is qualified. If the suction force received by the cross plate 18 is less than the elastic force of the spring 19, the cross plate 18 cannot be sucked onto the rubber pad 12, indicating that the suction force of the suction mechanism 5 is unqualified.
