Specifically, when the film 30 and the frame 40 are placed on the supporting structure 50, each of the lifting and lowering driving devices 90 drives the corresponding roller 80 to move toward the frame 40 and press the frame 40, so that the plurality of points between the frame 40 and the film 30 are bonded together first. Then, the linear module 70 drives the roller 80 to perform rolling translation along the frame 40, so as to achieve the adhesion between the frame 40 and the membrane 30. Like this, carry out the continuous roll extrusion translation between diaphragm 30 and the frame 40 earlier on the point pressure again, prevent that the two junction bubble from influencing the connection stability of the two, and then promote sticking film efficiency and the pad pasting quality of sticking film machine. Meanwhile, in the rolling process, the above movement mode of the roller 80 can avoid the sticking dislocation, the wrinkle and the deformation of the membrane 30 and the frame 40 caused by the stress accumulation caused by the tangential movement.

Alternatively, the elevation driving means 90 is a cylinder.

As shown in FIG. 4, the load bearing structure 50 includes a third vacuum assembly for engaging the membrane 30. The upper surface of the bearing structure 50 has a fourth absorption area 51, and the third vacuum pumping assembly absorbs the membrane 30 and the frame 40 through the fourth absorption area 51. Specifically, when diaphragm 30 and frame 40 were placed on bearing structure 50, the third evacuation subassembly adsorbed diaphragm 30, and second evacuation subassembly 23 adsorbs frame 40, ensures that relative motion can not take place between the two, promotes the degree of accuracy and the accuracy that the two bonded. Meanwhile, the third vacuumizing assembly can flatten the membrane 30 under the suction action of the membrane 30, so that the attached membrane 30 is smoother and more attractive.

In this embodiment, the frame 40 is bonded to the diaphragm 30 by the adhesive edge of the frame 40. Specifically, the adhesive edge of the frame 40 refers to a frame area to which adhesive glue is attached, and the adhesive glue is disposed on a side of the frame 40 facing the diaphragm 30.

The application also comprises a film sticking method, wherein the film sticking method comprises the following steps:

step S1: the driving device 10 drives the suction structure 20 of the film sticking machine to move, and when the suction structure 20 moves to the position of the membrane 30, the suction structure 20 sucks the membrane 30 through the vacuumizing assembly of at least one film sticking machine and places the membrane on the bearing structure 50 of the film sticking machine;

step S2: the vacuum pumping assembly stops operating to allow the suction cup 21 to release the membrane 30;

step S3: the driving device 10 drives the suction cup 21 to move, when the suction cup moves to the position of the frame 40, the suction cup 21 sucks the frame 40 through the vacuumizing assembly of at least one film sticking machine and places the frame on the film 30 on the bearing structure 50, and the laminating structure of the film sticking machine performs laminating on the film 30 and the frame 40 placed on the bearing structure 50.

Specifically, the driving device 10 transports the film 30 and the frame 40 through the suction cup 21, and the film 30 and the frame 40 are attached to each other after being transported to the bearing structure 50, so as to complete the attaching process of the film 30. In the above process, at least one vacuum-pumping assembly is used for attracting the membrane 30, at least one vacuum-pumping assembly is used for attracting the frame 40, and the working modes of the two vacuum-pumping assemblies can be independently controlled. The driving device 10 first transports the membrane 30 to the carrying structure 50, and then transports the frame 40 to the carrying structure 50, so that the frame 40 is attached to the membrane and located above the membrane 30. Compare with the laminating processing of adopting the manual diaphragm 30 and the frame 40 that carries on among the prior art, the sticking film machine in this embodiment not only can promote machining efficiency, and has reduced the processing defective percentage, has solved among the prior art that sticking film efficiency is lower, and has influenced the problem of pad pasting quality.

In the present embodiment, step S1 includes:

step S11: in the moving process of the suction structure 20, the positioning detection device 60 of the film sticking machine detects the specific position of the film 30, and when the film 30 is located at the first preset position, the first vacuum-pumping assembly 22 and the second vacuum-pumping assembly 23 of the film sticking machine are started, so that the film 30 is sucked on the suction cup 21;

step S12: the attraction structure 20 drives the membrane 30 to move, and when the membrane 30 moves above the bearing structure 50, the membrane 30 is attached to the bearing structure 50.

Specifically, during the transportation of the membrane 30, the specific position of the membrane 30 is detected by the positioning detection device 60, and when the positioning detection device 60 detects that the membrane 30 is located at the first preset position, the first vacuum pumping assembly 22 and/or the second vacuum pumping assembly 23 are/is in an open state and attract the membrane 30, so that the membrane 30 is attracted to the suction cup 21. The membrane 30 is then transported by the drive means 10 to fall onto the carrier structure 50 and to be brought into abutment with the carrier structure 50.

In this embodiment, in step S12, when the film 30 is attached to the supporting structure 50 by the attaching structure 20, the third vacuum pumping assembly of the supporting structure 50 starts to operate to attach the film 30.

In this embodiment, in step S2, the first and second vacuum pumping assemblies 22 and 23 are operated for a predetermined time or stopped after the third vacuum pumping assembly of the carrying structure 50 is operated, so that the film 30 is released and sucked on the carrying structure 50.

In the present embodiment, step S3 includes:

step S31: in the moving process of the suction structure 20, the positioning detection device 60 of the film sticking machine detects the specific position of the frame 40, and when the frame 40 is located at the second preset position, the second vacuum-pumping assembly 23 of the suction structure 20 is started to suck the frame 40 on the suction cup 21;

step S32: the suction structure drives the frame 40 to move, and when the frame 40 moves to the upper side of the bearing structure 50, the frame 40 is attached to the membrane 30, so that the frame 40 is connected with the membrane 30.

Specifically, in the transportation process of the frame 40, the specific position of the frame 40 is detected by the positioning detection device 60, and when the positioning detection device 60 detects that the frame 40 is located at the second preset position, the second vacuum pumping assembly 23 is in an open state and sucks the frame 40, so that the frame 40 is sucked on the suction cup 21. Then, the frame 40 is transported by the driving device 10, and when the driving device 10 moves to above the carrying structure 50, it descends onto the carrying structure 50, and keeps the second vacuum pumping assembly 23 in an open state to suck the frame 40, so that it falls on the film 30 on the carrying structure 50 and adheres to the film 30.

In this embodiment, after step S32, the method further includes: step S33: the lifting driving device 90 of the laminator drives the guide wheel assembly to move towards the frame 40, so that the roller 80 of the guide wheel assembly presses the rubber edge of the frame 40 and the membrane 30. Thus, the point pressing of the roller 80 against the diaphragm 30 is achieved by the above operation.

In this embodiment, in step S33, the linear module 70 of the film laminator drives the guide wheel assembly of the film laminator to move along the length direction X of the suction cup 21, so that the roller 80 of the guide wheel assembly rolls and translates on the rubber edge of the frame 40 and the film 30.

In this embodiment, in step S12, when the film 30 is attached to the supporting structure 50, the third vacuum pumping assembly of the supporting structure 50 operates to suck the film 30. Like this, when diaphragm 30 and frame 40 were placed on bearing structure 50, the third evacuation subassembly adsorbed diaphragm 30, and second evacuation subassembly 23 adsorbs frame 40, ensures that relative motion can not take place between the two, promotes the degree of accuracy and the accuracy that the two bonded.
