Description

Technical Field

[0001] The present invention relates to the technical field of automatic film laminating machines, in particular to a full-automatic film laminating machine for laminating films on three sides. Background Art

[0002] In order to prevent scratches on the TV frame before leaving the factory, it is often necessary to apply film. The traditional way of applying film is manual film application. However, due to the long length of the TV frame, manual film application is prone to deviation, and the film application effect is poor and the efficiency is low. The fully automatic film application machine in the prior art first attaches the protective film to the outer side of the frame, and then uses a scraper or roller to perform a second film scraping from the outer side to the front side, so that the protective film is bent and fits the front side. Therefore, attaching one side of the frame requires at least two steps of film application and film scraping. This results in slow film application speed and low efficiency. Two driving mechanisms are required to drive the film application device and the film scraping device to move respectively. The structure is complex and the cost is high. In addition, the existing fully automatic film application machine can only apply film on both sides of the side and front side of the frame, but cannot apply film on the rear side, resulting in low coverage of the protective film and inability to protect the rear side of the TV frame. Therefore, it is necessary to improve it. Summary of the invention

The film-drawing fixing frame 32 is slidably installed on the film-drawing fixing frame 2 along the horizontal direction, the film-drawing drive assembly is fixedly installed on the film-drawing fixing frame 2, the film-drawing drive assembly is transmission-connected with the film-drawing fixing frame 32, the film-drawing roller 33 is rotationally installed on the film-drawing fixing frame 32, the film-drawing plate 35 is slidably installed on the film-drawing fixing frame 32 along the horizontal direction, the film-drawing drive assembly is fixedly installed on the film-drawing fixing frame 32 and is transmission-connected with the film-drawing plate 35, and a film-drawing arc surface 352 matching the outer contour of the film-drawing roller 33 is provided on the side of the film-drawing roller 33 adjacent to the film-drawing roller 33, and the film-drawing arc surface 352 is movably abutted against the film-drawing roller 33.

[0054] The conventional fully automatic film laminating machine often rolls the protective film 91 to fit the outer side of the frame first, and then scrapes forward from the outer side by a scraper or roller, so that the protective film 91 is bent and fits to the front side of the frame to complete the laminating on both sides. Therefore, the length of the scraper or roller that fits the front side needs to cover the side of the frame, resulting in a large volume and a complex structure of the whole machine. It is necessary to first fit the outer side and then attach the front side for a second time. The film laminating steps are cumbersome and the film laminating efficiency is slow. The rear side cannot be laminarized, and the coverage of the protective film 91 is poor. The present invention drives the film laminating device 13 to move for film laminating by a robot 12. The film laminating device 13 first pulls out the rolled protective film 91 through the film pulling and attaching mechanism 3 and fits it to the frame 92. The protective film 91 is rolled and fixed on the outer side surface of the frame 92 by the positive film pressing mechanism 4. As the film pasting device 13 moves along the film pasting direction, the protective film 91 is bent to the front and rear sides by two bending mechanisms 51. Finally, the protective film 91 is rolled and fixed on the front and rear sides of the frame 92 by two side film pressing mechanisms 52. As the robot 12 drives the film pasting device 13 to move along the film pasting direction, the three sides of the frame 92 can be pasted at the same time without the film pasting device 13 moving back and forth. The film pasting efficiency is improved, the coverage of the protective film 91 is increased, the structure is simple and the cost is low. By setting a plurality of clamping and positioning devices 7 to fix a plurality of frames 92, the film pasting efficiency is further improved.

[0055] Specifically, the film clamping plate 35 is arranged below the film drawing roller 33, the film drawing fixing frame 32 is provided with a film clamping slide rail 361, the lower part of the film clamping plate 35 is provided with a film clamping slider 362, the film clamping slider 362 is slidably installed on the film clamping slide rail 361, the front side of the film clamping plate 35 is provided with a film scraping inclined surface 351 inclined from top to bottom and backward, and the film drawing fixing frame 32 is also rotatably installed with a first film guide roller 34, and the first film guide roller 34 is arranged at the rear side of the film drawing roller 33; the film drawing fixing frame 32 includes a film drawing bottom plate 321, a film drawing connecting shaft 321, and a film drawing connecting shaft 322. The film-drawing plate 322 and two film-drawing side plates 323, the film-drawing connecting plate 322 and the first film-drawing side plate 323 are respectively fixedly installed on both sides of the film-drawing bottom plate 321, the second film-drawing side plate 323 is fixedly installed in the middle of the film-drawing bottom plate 321, the film-drawing roller 33 and the two ends of the first film-guide roller 34 are respectively rotatably installed on the two film-drawing side plates 323, the film-clamping slide rail 361 is fixedly installed on the film-drawing bottom plate 321, the film-sticking fixing frame 2 is provided with a film-drawing slide groove 21, the film-drawing bottom plate 321 is slidably matched with the film-drawing slide groove 21, and the two film-drawing The film side plate 323 is located on the first side of the film fixing frame 2, and the film drawing connecting plate 322 is located on the second side of the film fixing frame 2. The second side of the film fixing frame 2 is provided with a film drawing slide rail 311, and the film drawing connecting plate 322 is provided with a film drawing slider 312. The film drawing slide rail 311 and the film drawing slider 312 are slidably matched. The film drawing drive assembly includes a film drawing drive cylinder 313 and two oil pressure buffers 314. The film drawing drive cylinder 313 is fixedly installed on the second side of the film fixing frame 2. The piston rod of the film drawing drive cylinder 313 is connected to the film drawing connecting plate 322. The connecting plate 322 is fixedly connected, and the two oil pressure buffers 314 are respectively fixedly installed on the second side of the film fixing frame 2 and are respectively located on the front and rear sides of the film pulling connecting plate 322, and the film pulling connecting plate 322 is abutted against the two oil pressure buffers 314; the film clamping driving assembly includes a film clamping driving cylinder 363 and a film clamping driving plate 364, and the film clamping driving cylinder 363 is fixedly installed on the rear part of the film pulling bottom plate 321, and one end of the film clamping driving plate 364 is connected to the piston rod of the film clamping driving cylinder 363, and the other end is connected to the film clamping plate 35.

[0056] In the initial state, if Figure 3 As shown, the protective film is pulled out from the film supply wheel 22, passes through the first film guide roller 34 between the film clamping plate 35 and the film drawing roller 33, and the film clamping driving cylinder 363 drives the film clamping driving plate 364 to move backward, and the film clamping driving plate 364 drives the film clamping plate 35 to move backward so that the film clamping arc surface 352 of the film clamping plate 35 abuts against the film drawing roller 33, thereby clamping and fixing the protective film 91 between the film clamping plate 35 and the film drawing roller 33;

[0057] When film pasting is being performed, the robot 12 drives the film pasting device 13 to move to the end of the side of the frame 92 as the starting position. Figure 4As shown, the film-drawing driving cylinder 313 drives the film-drawing fixing frame 32 to move toward the frame 92 until the protective film 91 on the film-drawing roller 33 is pressed against the outer side of the frame 92, as shown in FIG. Figure 5 As shown, the film clamping driving cylinder 363 then drives the film clamping driving plate 364 to move forward, and the film clamping driving plate 364 drives the film clamping plate 35 to move forward, so that the film clamping arc surface 352 is separated from the film pulling roller 33, thereby loosening the protective film 91. At this time, the film clamping plate 35 lightly touches the frame 92, and the contact area between the film clamping plate 35 and the frame 92 is reduced by the film scraping inclined surface 351. The manipulator 12 drives the film pasting device 13 to continue to move in the film pasting direction. The film clamping plate 35 can clean foreign matter on the frame 92 when attaching the protective film, thereby improving the success rate of film pasting.

[0058] The film-pulling fixing frame 32 is arranged on the first side of the film-sticking fixing frame 2, and the film-pulling driving assembly is arranged on the second side of the film-sticking fixing frame 2, thereby reducing the space required for installation, making the film-sticking device 13 more compact in structure and reducing the volume; the film-pulling fixing frame 32 is limited by two oil pressure buffers 314, which also play a buffering role at the same time, thereby increasing the moving speed of the film-pulling fixing frame 32 and further improving the film-sticking efficiency.

[0059] Specifically, the positive pressure film mechanism 4 includes a positive pressure door type fixing frame 42, a positive pressure door type connecting frame 43, a positive pressure slide cylinder 44 and a positive pressure roller 41. The positive pressure door type fixing frame 42 is fixedly installed on the first side of the film fixing frame 2, the positive pressure slide cylinder 44 is fixedly installed on the positive pressure door type fixing frame 42, the positive pressure door type connecting frame 43 is fixedly installed on the slide of the positive pressure slide cylinder 44, and the positive pressure roller 41 is rotatably installed on the positive pressure door type connecting frame 43. After the film-pulling and attaching mechanism 3 pulls out the rolled protective film 91 and attaches it to the outer side of the frame 92, the positive pressure slide cylinder 44 drives the positive pressure door-type connecting frame 43 to move forward, thereby driving the positive pressure roller 41 to move forward and press against the frame 92. As the film-attaching device 13 moves along the film-attaching direction, the positive pressure roller 41 presses the protective film 92 against the outer side of the frame 91.
