Referring to FIGS. 5 and 6, the vertical drive assembly 33 includes: mounting plate 331, lead screw drive assembly, straight line module 332 and lift slip table 333. Wherein the mounting plate 331 is connected to the output end of the longitudinal driving assembly 32 to follow the longitudinal driving assembly 32. The screw rod driving component is arranged on the mounting plate 331 and used for driving the lifting sliding table 333 to lift vertically. The linear module 332 is disposed between the lifting sliding table 333 and the mounting plate 331, and is configured to provide vertical guidance for the lifting sliding table 333 when the lifting sliding table 333 is lifted, and the pickup mechanism 4 is connected to the lifting sliding table 333 through the angle adjusting component 34.

With particular reference to fig. 6, the lead screw drive assembly includes: the servo motor 334 is arranged on the mounting plate 331, the ball screw 335 is connected with the movable end of the servo motor 334, and the screw nut 336 is arranged on the ball screw 335. Preferably, the servo motor 334 and the ball screw 335 may be disposed on two sides of the mounting plate 331, and the servo motor 334 and the ball screw 335 are connected by a gear belt 337. Of course, the servo motor 334 may also be disposed on the same side as the ball screw 335, and the servo motor 334 may directly drive the ball screw 335 to rotate through a coupling. Further, a flexible displacement mechanism 338 is arranged between the screw nut 336 and the lifting sliding table 333, and the flexible displacement mechanism 338 can control and adjust the lower pressure degree of the picking mechanism 4 when the picking mechanism 4 is pressed down, so as to avoid damage to the film and the feeding device itself due to the excessively high lower pressure degree.

Referring with emphasis to FIG. 6, the flexible displacement mechanism 338 includes: a screw nut mount 3381, an elastic member 3382, and a guide bar 3383. The lead screw nut mounting seat 3381 is connected to the lead screw nut 336 and the lifting sliding table 333 respectively. The ball screw 335 is driven to rotate by the servo motor 334, and further the screw nut 336 and the screw nut mounting block 3381 connected to the screw nut 336 are pushed to move, and the guide bar 3383 prevents the screw nut 336 from rotating together with the ball screw 335, thereby converting the rotational motion of the ball screw 335 into the linear motion of the screw nut mounting block 3381.

The one end of guide bar 3383 with promote slip table 333 fixed connection, the other end of guide bar 3383 runs through screw-nut mount 3381 is connected with a fastener, screw-nut mount 3381 and guide bar 3383 clearance fit, elastic component 3382 cover is established on the guide bar 3383. Further, the elastic element 3382 is preferably a compression spring, and under the action of the compression spring, the lifting sliding table 333 and the lead screw nut mounting seat 3381 generate linkage displacement. Specifically, when there is no external resistance, the lifting slide table 333 will always follow the lead screw nut 336 to perform linear displacement. However, when the lifting slide table 333 encounters resistance, for example, after the pickup mechanism 4 puts the film into the edge deletion mold 120, when the vertical driving assembly 33 controls the pickup mechanism 4 to continuously move downward until the film contacts with the lower mold of the edge deletion mold 120, the lifting slide table 333 is affected by the resistance of the lower mold of the edge deletion mold 120 and cannot continuously move downward, so that the lead screw nut 336 compresses the elastic member 3382 through the lead screw nut mounting seat 3381, which can ensure that the lead screw nut 336 can continuously move downward, and can provide buffering for the pickup mechanism 4, thereby preventing the pickup mechanism 4 from applying excessive pressure downward.

The photographing mechanism 2 includes a camera 21 and a light source 22. In this embodiment, the camera 21 and the light source 22 may be directly fixed above the conveying mechanism 1 through a mounting frame, and are always fixed. Or may be disposed above the conveyor 1 and follow the transverse drive assembly 31 to move back and forth. The present embodiment preferably arranges the photographing mechanism 2 at one side of the stand 35. When the camera 21 works, the camera 21 can shoot the film on the conveying belt 11, and the shooting information is transmitted to an upper computer, a control computing system is configured in the upper computer, and the control computing system can acquire the plane position information of the film on the conveying belt 11. The offset distance of the film in the transverse direction and the longitudinal direction from the reference position and the deflection angle in the rotation direction of the vertical axis can be obtained by analytically determining the plane position information on the conveyor belt 11.

Furthermore, the shape of the profiling sucking disc 42 is matched with that of the film, compared with a common sucking disc, the profiling sucking disc 42 can eliminate deformation of the film caused by soft material in the taking and placing process, the position offset of the film in the taking and placing process can be reduced, and the punching quality is improved.

Preferably, the picking mechanism 4 further includes an atomizing nozzle 43 and/or a blowing nozzle 44 disposed at an end of the tooling connection plate 41 far away from the position adjusting mechanism 3. The atomizing nozzle 43 can perform atomizing spraying on the trimming die 120 in the trimming device 100 as required to improve the punching quality. The blowing nozzle 44 can blow the punching residual material away from the trimming die 120 by the cooperation of the blowing nozzle 44 provided in the trimming die 120 after the punching is completed.

Referring to fig. 1 to 6, the work flow of the automatic edge removing machine of the present invention is as follows:

the transport mechanism 1 receives the film. Specifically, the film is placed at the discharging station of the conveying belt 11 by the previous process equipment, such as an automatic feeder or a discharging mechanism of a film production conveying line.

The motor 12 controls the conveyor belt 11 to move at a certain speed, so that the film is transferred to the material taking station.

The shooting mechanism 2 shoots the film on the conveying belt 11 and determines the position of the film on the conveying belt 11.

The position adjusting mechanism 3 controls the pickup mechanism 4 to act according to the position information of the film in the shooting mechanism 2, and the film is sucked at the corresponding position.

The picking mechanism 4 is driven by the position adjusting mechanism 3 to move to the feeding end of the edge removing die 120, the material blowing nozzle 44 positioned at the end part of the tool connecting plate 41 is opened, and the punching residual cutting material on the edge removing die 120 is blown away in the process that the picking mechanism 4 and the film are sent into the edge removing die 120 by the position adjusting mechanism 3.

Next, the atomizing nozzle 43 is opened, and the surface of the trimming mold 120 is atomized and sprayed while the pickup mechanism 4 together with the film is fed into the trimming mold 120 by the position adjusting mechanism 3.

The position adjustment mechanism 3 then moves to feed the pickup mechanism 4 and the film into the corresponding position of the edge deletion mold 120, and controls a certain downward pressure to accurately feed and press the film into the edge deletion mold 120 through the flexible displacement mechanism 338 if necessary.

It should be noted that, because the conveying mechanism 1 continuously steps, while the position adjusting mechanism 3 transfers and places the film to the edge removing mold 120, the conveying mechanism 1 and the shooting mechanism 2 also work synchronously, after the film is placed, the position adjusting mechanism 3 can directly get the film to the material taking station, and the above steps are repeated in a circulating manner.
