[0036] When the side suction part 3 is in the pasting position, the included angle between the suction surface of the side suction part 3 and the suction surface of the bottom suction part 2 is an acute angle.

[0037] The side suction part 3 has a moving space 35 on the side close to the bottom suction part 2, and the mounting frame 1 is provided with a scraping plate 10 through a lifting member 11, and the lifting member 11 drives the scraping plate 10 to rise and fall to realize the pasting and smoothing on the connecting piece of the cover plate 7 on the side suction part 3.

[0038] It should be noted that the mounting frame 1 is connected with a mechanical hand outside, and the mechanical hand is used to drive the mounting frame 1 to move in the horizontal plane and to rise and fall in the vertical plane. The moving, rotating of the component in the horizontal plane or the rising and falling of the component in the vertical plane driven by the mechanical hand outside is a conventional technology, and therefore, the mechanical hand is not embodied in the drawings.

[0039] The mechanical hand is used to drive the mounting frame 1 to move above the film 8, and then to drive the mounting frame 1 to move downward to make the bottom suction part 2 and the side suction part 3 suck the film 8, and then to drive the mounting frame 1 to move to the direction close to the connecting piece of the cover plate 7, and then to drive the side suction part 3 to rotate through the rotating mechanism 4 and make the side suction part 3 in the pasting position, and in this process, the film 8 is bent.

[0042] When the bottom suction part 2 and the side suction part 3 do not suck the film 8, the film 8 is placed on the placing plate 9, and the placing plate 9 sucks the film 8 through negative pressure, in order to prevent the film 8 from being deformed greatly in the bending process, such as Figure 4As shown, in this invention, preferably, the placement plate 9 has a first placement portion 90 and a second placement portion 91, which are connected by a vertical connecting portion 92, so that the height of the second placement portion 91 is slightly higher than the height of the first placement portion 90, and the first placement portion 90 and the second placement portion 91 are connected by a vertical surface, so that the film 8 placed on the placement plate 9 is in a bent state, the bottom adsorption portion 2 adsorbs a portion of the film 8 on the second placement portion 91, and the side adsorption portion 3 adsorbs a portion of the film 8 on the first placement portion 90. When the side adsorption portion 3 is in a horizontal position, there is a gap between the adsorption surface of the side adsorption portion 3 and the adsorption surface of the bottom adsorption portion 2, and the film 8 between the side adsorption portion 3 and the bottom adsorption portion 2 is in a relaxed state, so as to prevent the film 8 from being pulled when the side adsorption portion 3 is rotated to the adhesive application position.

[0043] During the operation, the side adsorption part 3 is in a horizontal position, and then the mounting frame 1 moves the side adsorption part 3 and the bottom adsorption part 2 to the film 8 with the bending part, and the side adsorption part 3 and the bottom adsorption part 2 adsorb the film 8.

[0044] The rotating mechanism 4 drives the side adsorption part 3 to rotate to the adhesive application station so that the adhesive sheet 8 is in a bent state;

[0045] The mounting bracket 1 moves the side adsorption part 3 and the bottom adsorption part 2 to above the connecting piece of the cover plate 7. The mounting bracket 1 moves the film 8 and makes the film 8 corresponding to the adsorption surface of the bottom adsorption part 2 stick to the connecting piece of the cover plate 7. Then the lifting member 11 moves the scraper plate 10 upward so that the film adsorbed by the side adsorption part 3 sticks to the connecting piece of the cover plate 7 and smooths it out.

[0046] like Figure 4 As shown, in some preferred embodiments, the side adsorption part 3 includes a first side frame and a second side frame.

[0051] The mounting frame 1 is provided with a scraping plate 10 through a lifting member 11, the scraping plate 10 is located in the moving space 35, and the lifting member 11 drives the scraping plate 10 to move upward in the moving space 35 to realize smoothing of the adhesive sheet 8 attached to the connecting piece of the cover plate 7. The movement of the lifting member 11 driving the scraping plate 10 in the moving space 35 realizes the attachment and smoothing of the adhesive sheet 8 below, and then the negative pressure of the side adsorption part 3 and the bottom adsorption part 2 is removed, and the mounting frame 1 is driven upward by the mechanical hand to realize the attachment and smoothing of the adhesive sheet 8 above. The lifting member 11 can be an electric cylinder or an air cylinder in the prior art.

It should be noted that the first telescopic member 12 can be an electric cylinder or an air cylinder in the prior art.

[0053] In the working process, the side adsorption part 3 is in a horizontal position, and then the mounting frame 1 drives the side adsorption part 3 and the bottom adsorption part 2 to move to the adhesive sheet 8 having a bending part, and the side adsorption part 3 and the bottom adsorption part 2 adsorb the adhesive sheet 8;

[0054] The side adsorption part 3 is rotated to a gluing position to make the adhesive sheet 8 in a bending state;

[0057] Then the lifting member 11 drives the scraping plate 10 to move upward to realize attachment and smoothing of the adhesive sheet 8 opposite to the moving space 35, and the adhesive sheet 8 contacts the connecting piece of the cover plate 7 and is smoothed.

[0058] Then, the negative pressure on the bottom adsorption part 2 and the side adsorption part 3 is removed, and the robotic arm moves the mounting frame 1 upward to achieve the bonding of the film located outside the active space 35. Smoothing.

After the elastic member 15 is compressed a certain distance, the clamping frame 13 contacts the film 8 and the corner of the film 8 contacts the corner of the connecting piece of the cover plate 7. And when the lifting member 11 moves the scraper plate 10 to the uppermost position, the extension plate 130 can also press against the scraper plate 10, so that even if the robot arm shakes during the vertical movement of the mounting frame 1, the scraper plate 10 can still press against the film 8.
