Still further, a guide sleeve 45 is arranged on the second fixing plate 41, a second guide pillar 46 is slidably arranged in the guide sleeve 45, a limiting plate 47 is arranged at the upper end of the second guide pillar 46, and the lower end of the second guide pillar is fixedly connected with the lifting plate 43.

As is well known, the automobile handrail frameworks comprise a left station and a right station, so that the stations in the equipment comprise two mirror-image stations, namely, the left automobile handrail framework and the right automobile handrail framework can be simultaneously pasted with films.

The working process of the equipment is as follows: the control device is a PLC, and the control device is connected with the first driving unit 5, the second driving unit 26, the sensor, the fan, the clamping device, the third driver 3332, the fourth driving unit 343, and the fifth driving unit 42 in a control manner; the reel-shaped film is placed on the film re-placing mechanism 2, and the control device controls the second driving unit 26 to rotate, so that the reel-shaped film is pulled out and then is flattened on the platform plate 23; the control device controls the first driving unit 5 to move, and the film sticking mechanism 4 is driven to move to a corresponding position and then stops moving; the control device controls the fifth driving unit 42 to move, so that the film placing assembly descends and contacts with the film on the platform plate 23, and then the fan is started, so that the suction plate 441 generates vacuum to suck the film on the suction plate 441; after controlling the fifth driving unit 42 to return to the initial state, controlling the first driving unit 5 to move to the corresponding position of the handrail fixing mechanism 3; controlling the fifth driving unit 42 to descend and enabling the film to be in contact with the automobile handrail framework; starting a fan and spraying gas outwards through the suction plate 441 to enable the film to be uniformly fixed, and then finishing film pasting on the automobile handrail framework; simultaneously starting the fifth driving unit 42 and the fourth driving unit 343, wherein the fifth driving unit 42 enables the film sticking assembly to be restored to the initial state, and the fourth driving unit 343 turns the handrail fixing mechanism 3 by 180 degrees and controls the clamping device to be loosened, so that the automobile handrail framework which is subjected to film sticking falls on the inclined conveying mechanism 6; after the operation is finished, the control device controls the first driving unit 5 to move the film sticking mechanism 4 to the film placing mechanism 2, controls the fourth driving unit 343 to turn the handrail fixing mechanism 3 for 180 degrees to recover to the initial state, and controls the third driver 3332 to move, so that the positioning clamp 32 is in a horizontal state, and the manipulator can conveniently place the automobile handrail framework in; the third driver 3332 is controlled to be restored to the initial state after the insertion.

While embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application of the invention, and further modifications may readily be effected by those skilled in the art, so that the invention is not limited to the specific details without departing from the general concept defined by the claims and the scope of equivalents.
