[0002] Flexible circuit boards, also known as soft circuit boards and flexible circuit boards, are highly favored for their light weight, thin thickness, free bending and folding and other excellent properties. In the flexible circuit board industry, the role of FPC covering film is mainly to protect the copper foil from being exposed to the air to prevent oxidation and to cover the subsequent surface treatment. During the transportation and protection process of the FPC covering film, a layer of base paper is covered on the film. The base paper needs to be separated before using the protective film. Most FPC covering processes are to first peel off the base paper from the FPC covering film material, then stick the FPC covering film to the copper foil, and finally peel off the film material.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Combination Figure 1 and Figure 2 , Figure 6 As shown, an FPC laminating machine film extrusion device described in an embodiment of the present invention includes a base 1, a film clamping bin 2 and a film material bin 3 are fixedly connected to the top of the base 1, an electric control switch 4 is fixedly connected to the inner top wall of the film material bin 3, an electric telescopic cylinder 5 is arranged at the bottom of the electric telescopic cylinder 5, a guide plate 6 is fixedly connected to the bottom of the guide plate 6, an extrusion assembly is installed at the bottom of the guide plate 6, the extrusion assembly is used to separate the circuit board material and the film, so as to facilitate the film cornering, and the inner top wall of the film clamping bin 2 is installed with an electric control switch 2 7. An electric telescopic rod 9 is arranged at the bottom of the electric control switch 2 7, and an adsorption box is arranged at the bottom of the electric telescopic rod 9, and the adsorption box is used to collect the film. The film clamping bin 2 is fixedly connected with a accommodating chamber 1 8, and the film material bin 3 is fixedly connected with a accommodating chamber 2 80. A notch is arranged above the accommodating chamber 2 80, and a film pressing roller 65 is rotatably connected in the notch. The film pressing roller 65 presses on the circuit board material and the film, and a direct drive motor is arranged at one end of the film pressing roller 65. A film clamping assembly is arranged at the bottom of the accommodating chamber 1 8, and the film clamping assembly is used to clamp the film.

[0036] During operation, when it is necessary to perform angle treatment on the circuit board material and the film, the film pressing roller 65 is powered on and rotated to squeeze downward to press the formed circuit board material and the film, and the extrusion component is started. The extrusion component moves downward to first contact the upper film, and friction is generated after contact. The friction twists the film to make it angled, and then the circuit board material and the film are pushed toward the film clamping bin 2, and the film clamping component is started. The film clamping component moves toward the film material bin 3. When the film clamping component moves to the position of the film, it clamps the sticker by bringing the upper and lower parts together, and takes out the film by pulling back, thereby solving the angle problem caused by the difficulty in tearing the film.

[0037] Combination Figure 3 and Figure 4 As shown, the extrusion assembly includes an eccentric block 61, a toggle roller 62 is arranged on the inner surface of the eccentric block 61, the center of the toggle roller 62 is fixedly connected to a main shaft 63, the end of the main shaft 63 is fixedly connected to a sliding plate 60, the outer surface of the sliding plate 60 is slidably connected to a guide block 64, the sliding plate 60 is used to slide in the slide groove, the guide block 64 is fixedly connected to the inner wall of the film silo 3, the outer surface of the toggle roller 62 is installed with an adsorption sheet, the inner top wall of the guide block 64 is installed with a reset spring, and the reset spring is separated from the main shaft 63; the inner side wall of the guide block 64 is provided with a slide groove that matches the specifications and dimensions of the sliding plate 60;

[0038] Before taking the film away, the film needs to be twisted upward to form a starting angle. Using the embodiment of the present invention, the electric telescopic cylinder 5 is started, and the electric telescopic cylinder 5 pushes the guide plate 6 downward, and the guide plate 6 drives the eccentric block 61 to move downward, and the eccentric block 61 moves downward to contact and squeeze the swivel roller 62. After being squeezed, the swivel roller 62 moves downward, and the swivel roller 62 drives the main shaft 63 and the sliding plate 60 to move synchronously. The reset spring is gradually stretched at this time, and the sliding plate 60 slides down along the slide groove. When the swivel roller 62 moves to the inner bottom wall of the guide block 64, the adsorption sheet of the swivel roller 62 contacts the film above the circuit board material, and the adsorption sheet adsorbs the film, which is convenient for the subsequent twisting of the film.

[0039] When the eccentric block 61 slides downward and contacts one side of the paddle roller 62, friction is generated, and the friction causes the paddle roller 62 to deflect, and then return to its original state. The paddle roller 62 uses this deflection force to twist the film, and after the twisting, the circuit board material and the film are separated, thereby forming an upward angle, which is convenient for the subsequent removal of the film.

[0040] like Figure 5 , Fig.10 As shown, an expansion component is installed on the top of the base 1, and the expansion component is used to improve the separation effect of the circuit board material and the film. The expansion component includes a film pushing member 66, and a rotating shaft 71 is rotatably connected to the inner cavity of the film pushing member 66. A servo motor is externally connected to one end of the rotating shaft 71, and the output end of the servo motor is connected to the rotating shaft 71. A crank plate 70 is fixedly connected to the other end of the rotating shaft 71, and a rotating rod 69 is sleeved on the end of the crank plate 70. One end of the rotating rod 69 is rotatably connected to a moving block 68, and the end of the moving block 68 away from the crank plate 70 is fixedly connected to a rack plate 72. A guide rail 76 is provided on the outer surface of the rack plate 72, and the guide rail 76 is fixedly installed on the top of the base 1. The end of the rack plate 72 is rotatably connected to a gear plate 74, and a thin shaft 75 is fixedly connected to the inner wall of the gear plate 74.

[0041] During operation, due to the limited range of the starting angle, the subsequent film removal will have a problem of a small clamping range and difficulty in removing. Therefore, using the embodiment of the present invention, the rotating shaft 71 is energized to drive the crank plate 70 to rotate, and the crank plate 70 drives the rotating rod 69 to rotate. When the rotating rod 69 rotates to the position of the moving block 68, the rotating rod 69 squeezes the moving block 68 to move, and the moving block 68 squeezes the rack plate 72 to move. The rack plate 72 moves along the inside of the guide rail 76 toward the direction close to the thin shaft 75. After the rack plate 72 moves to the position of the gear plate 74 The rack plate 72 is meshed with the gear plate 74, and the gear plate 74 is meshed and twisted. The twisting of the gear plate 74 drives the thin shaft 75 to move, and the thin shaft 75 rotates in the direction close to the crank plate 70. After the thin shaft 75 rotates, it contacts the upper membrane, and the membrane is pushed by the thin shaft 75. The separation between the membrane and the circuit board material is increased, which reduces the difficulty of clamping the starting angle between the circuit board material and the membrane, thereby facilitating the subsequent smooth clamping and removal of the membrane; it should be noted that the starting angle position is located at the edge of the accommodating cavity 80.

[0042] like Figures 7 and 8 The clamping membrane assembly includes an assembly seat 81 installed on the top of the accommodating cavity 8, and the sides of the assembly seat 81 are fixedly connected with linkage strips 82. The sides of the assembly seat 81 are fixedly connected with mounting seats 86. An electromagnetic plug-in plate 84 is plugged on the top of the mounting seat 86, and an electromagnetic cover plate 83 is plugged on the top of the electromagnetic plug-in plate 84. An induction switch is arranged on the top of the electromagnetic cover plate 83, and an electromagnetic plug-in plate 84 is arranged on the bottom of the electromagnetic cover plate 83. The electromagnetic plug-in plate 84 is located inside the mounting seat 86, and the sides of the electromagnetic plug-in plate 84 are fixedly connected with curved arc strips 85. A limiting groove is arranged inside the mounting seat 86. The limiting An upper card plate 87 and a lower card plate 88 are arranged inside the positioning groove, the positioning groove is slidably connected to the upper card plate 87, and the positioning groove is fixedly connected to the lower card plate 88, and the upper card plate 87 is located above the lower card plate 88; a plug-in slot is provided on the top of the mounting seat 86, and the plug-in slot is adapted to the size of the electromagnetic plug-in plate 84, and the width of the electromagnetic cover plate 83 is larger than the plug-in slot on the top of the mounting seat 86 to prevent detachment when plugging downward; a controller and an electric slider 1 are installed at the bottom of the assembly seat 81, and the electric slider 1 is fixedly connected to the assembly seat 81, and a slide rail adapted to the linkage bar 82 is provided on the inner wall of the film clamping bin 2.

[0043] During operation, when it is necessary to clamp and remove the film, the embodiment of the present invention is used, the roller 62 is moved downward, the controller is started, and the electric slider 1 is energized to drive the assembly seat 81 to move, and the assembly seat 81 drives the linkage bar 82 and the mounting seat 86 to move in the direction of the film silo 3. After moving to the position where the film starts to angle, the induction switch is turned on, and the electric slider 2 is energized to move. The electric slider 2 drives the electromagnetic plug-in plate 84 downward to move, and the electromagnetic plug-in plate 84 is plugged into the inside of the mounting seat 86. The electromagnetic plug-in plate 84 drives the bending bar 85 to move, and the bending bar 85 presses the upper clamping plate 87 downward, and the upper clamping plate 87 moves downward to move closer to the lower clamping plate 88. When the upper clamping plate 87 and the lower clamping plate 88 move closer, the film with the angle is clamped, and after the resetting action of the controller, the film is removed from the film silo 3.

[0044] like Fig. 9 As shown, the upper clamping plate 87 includes a reinforcement component, which is used to prevent the clamping film from being loose or loose. The reinforcement component includes a plurality of placement cavities 871, a clamping block 872 is fixedly connected to the bottom of the placement cavity 871, a limiting block 874 is fixedly connected to the bottom end of the clamping block 872, a slot 873 is provided in the middle of the limiting block 874, a hole of the same size as the slot 873 is provided in the clamping block 872, a telescopic piece 875 is telescopically connected to the inner cavity of the placement cavity 871, a plurality of dredging strips 876 are fixedly connected in the middle of the lower clamping plate 88, a through groove matched with the telescopic piece 875 is provided on the placement cavity 871, the placement cavity 871 is made of stainless steel, and the interior of the clamping block 872 is a cavity, the dredging strip 876 matches the specifications and dimensions of the slot 873, the telescopic piece 875 is in an "M" shape, and the telescopic piece 875 is made of elastic material.

[0045] During the clamping process, as the number of clamping times increases, the performance of the curved strip 85 decreases, the clamping gap between the upper clamping plate 87 and the lower clamping plate 88 may become larger, and the membrane is relatively thin, so the clamping may not be tight. Therefore, when the upper clamping plate 87 moves downward, the upper clamping plate 87 drives the placement cavity 871 to move downward synchronously, and the placement cavity 871 drives the card block 872 to move. The card block 872 moves downward and approaches multiple dredging strips 876. The dredging strips 876 are inserted into the card slots 873 and into the interior of the card block 872. The dredging strips 876 contact the telescopic sheet 875, and the telescopic sheet 875 extends out to both sides after being squeezed. The telescopic sheet 875 is gradually squeezed with the membrane for a second time, and the membrane is not easy to loosen after being squeezed, thereby improving the clamping strength.

[0046] like Figures 11 to 13As shown, a concave limiting groove is provided inside the upper clamping plate 87, a placement seat 877 is installed inside the concave limiting groove, a vertical plate 878 is fixedly connected to the bottom of the placement seat 877, a pressing piece 879 is fixedly connected to the bottom of the vertical plate 878, a plug rod 880 is rotatably connected inside the pressing piece 879, an outer cylinder 881 is sleeved on the outer surface of the plug rod 880, and a tension spring 882 is installed outside the outer cylinder 881;

[0047] During operation, due to the secondary extrusion of the outer surface of the expansion piece 875 and the film, wrinkles may appear on the extruded part of the film, and the wrinkles will be detrimental to the processing of the film. Using the embodiment of the present invention, when the expansion piece 875 extends downward, the expansion piece 875 squeezes the outer tube 881 to move downward, and the outer tube 881 presses the film under the expansion piece 875 downward, thereby preventing the problem of wrinkles.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
