Description

Technical Field

[0001] The invention relates to the technical field of circuit board production, and in particular to a high-performance flexible circuit board substrate film laminating machine equipment. Background Art

[0002] Flexible circuit board is a kind of printed circuit board with high reliability and excellent flexibility made of polyimide or polyester film as the substrate. It has the characteristics of high wiring density, light weight, thin thickness, good bending, can be bent and folded at will, small size, good heat dissipation, easy installation, breaking through the traditional technology. In the production of flexible circuit board, protective film needs to be attached to the surface of both sides to provide protection for the middle circuit board base. The existing technology usually presses the protective film on the surface of the circuit board base through a hot pressing process.

[0003] After searching, a Chinese patent with publication number: CN117156707A discloses a laminating device for FPC board manufacturing, including a base and an equipment seat above the base, a hot pressing roller is installed at the lower end of the equipment seat, and a feeding mechanism located in front of the hot pressing roller is installed on the base, the hot pressing roller includes two end plates, an electric heating tube is airtightly connected between the two end plates, and a thermal conductive silicone is sleeved on the outer wall of the electric heating tube; a rotating shaft is installed on both of the end plates, and an end of one of the rotating shafts extends to the interior of the equipment seat and is connected to a driven wheel.

[0004] Based on the above search and combined with actual problems, it is found that the existing bonding equipment for circuit boards usually needs to use rollers to pull the protective film and the circuit board substrate. However, in actual use, due to factors such as the gap between the rollers or the speed difference between the rollers, the film will be subjected to uneven tension. The uneven tension can easily cause the protective film to deform, thereby causing the protective film to have longitudinal wrinkles in the same direction as its movement. The wrinkles will cause the surface of the circuit board to be uneven after the protective film is bonded to the circuit board substrate, and bubbles will be generated between the circuit board substrate and the protective film, thereby reducing the production quality of the circuit board.

As the rotating drum rotates, the multiple arc plates on one side close to the pressing mechanism are separated, and the multiple arc plates on the other side are closed. Therefore, when the rotating drum pulls the protective film to move, the multiple arc plates at the two ends of the rotating drum can apply reverse forces from both sides of the protective film, so that the protective film can be pulled laterally, thereby preventing longitudinal wrinkles from being generated on the protective film during the pulling process. Therefore, the flatness of the protective film during pulling can be ensured, thereby improving the fit between the protective film and the circuit board substrate, avoiding the generation of bubbles between the protective film and the circuit board substrate, and greatly improving the film pressing quality.

[0018] Secondly, the present invention uses the adsorption mechanism in each slider to increase the air pressure difference so that the protective film fits tightly to the surface of the anti-slip pad while the arc plate applies pulling force to the side of the protective film, thereby increasing the friction between the protective film and the anti-slip pad. When the two sides of the protective film are pulled, the relative sliding between the arc plate and the protective film can be reduced, the pulling effect is improved, and the longitudinal wrinkles on the protective film can be fully eliminated.

DETAILED DESCRIPTION

[0032] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention provides a high-performance flexible circuit board substrate film laminating machine device through improvement. The technical solution of the present invention is:

[0034] like Figures 1 to 10As shown, an embodiment of the present invention provides a high-performance flexible circuit board substrate film laminating machine device, including a bottom plate 1, a laminating mechanism is arranged on the upper side of the bottom plate 1, two fourth side plates 101 are fixed at the middle position on the upper side of the bottom plate 1, two anti-wrinkle mechanisms arranged up and down are arranged between the two fourth side plates 101, and a driving mechanism for driving the two anti-wrinkle mechanisms to rotate in opposite directions is arranged between the two anti-wrinkle mechanisms; the anti-wrinkle mechanism includes a rotating shaft 103 rotatably connected to the inside of one fourth side plate 101 and a rotating shaft 103 fixed to the other fourth side plate A fixed rod 102 is inside 101, and a rotating cylinder 104 is fixed on the outside of the fixed rod 102 for rotation. A plurality of circumferentially arranged sliding grooves 105 are provided at both ends of the outer side of the rotating cylinder 104. A slider 107 is slidably connected to the inner side of each sliding groove 105. An arc plate 108 is fixed at one end of each slider 107. A transmission mechanism is provided between the plurality of sliders 107 at the same end and the fixed rod 102, and the transmission mechanism is used to drive the slider 107 to move inside the sliding groove 105.

[0035] Further, the transmission mechanism includes a roller 202 rotatably connected to one end of each slider 107, a guide slot column 201 fixed to one end of the outer side of the fixed rod 102, a guide slot structure for driving the slider 107 to move linearly is provided on the outer side of the guide slot column 201, and the guide slot structure includes a separation guide slot 203, a merging guide slot 204 and a transposition bevel 205 provided on the outer side of the guide slot column 201, the separation guide slot 203 is far away from the middle section of the fixed rod 102, the merging guide slot 204 is close to the middle section of the fixed rod 102, the number of the transposition bevel 205 is two, and the two transposition bevel slots 205 are respectively located on opposite sides of the guide slot column 201, the two ends of the separation guide slot 203 and the merging guide slot 204 are smoothly connected by two transposition bevel slots 205, the separation guide slot 203 faces the direction of the pressing mechanism, and the separation guide slot 203 is vertically arranged, and the two transposition bevel slots 205 are respectively located on the uppermost and lowermost sides of the guide slot column 201;

[0036] Through the transmission mechanism, the multiple curved plates 108 located on the side of the rotating drum 104 close to the pressing mechanism can be separated, and the multiple curved plates 108 located on the other side of the rotating drum 104 can be closed. Therefore, when the rotating drum 104 pulls the protective film to move, the multiple curved plates 108 at both ends of the rotating drum 104 and close to the pressing mechanism can apply reverse forces from both sides of the protective film, so that the protective film can be pulled laterally, thereby preventing longitudinal wrinkles on the protective film during the pulling process, thereby ensuring the flatness of the protective film during pulling, thereby improving the fit between the protective film and the circuit board substrate.

[0037] Furthermore, six guide rods 106 arranged in a circle are fixed to the inner side of the rotating drum 104, and both ends of each guide rod 106 are respectively slidably inserted into the slider 107 at the corresponding position, and an adsorption mechanism is arranged between each slider 107, the arc plate 108 and the guide rod 106, and the adsorption mechanism includes an arc cavity 301 opened inside the arc plate 108, an air channel 303 and an air extraction cavity 304 opened inside the slider 107, and a plurality of air holes 302 are evenly opened on one side of the arc cavity 301, and the arc cavity 301 is connected to the air channel 303, and one end of the air channel 303 is connected to the air channel 304 by connecting the air channel 304 to the air channel 304. The tube 308 is connected to the inside of the air pumping chamber 304, and a push-pull rod 305 is slidably inserted at one end of the air pumping chamber 304. One end of the push-pull rod 305 is fixed to the guide rod 106 through a fixing plate 306, and the other end of the push-pull rod 305 is elastically connected to a pumping piston plate 307, and the pumping piston plate 307 is slidably connected to the inner side of the air pumping chamber 304. An anti-skid pad 109 is fixed to the outside of each arc plate 108, and a plurality of cushion air holes aligned with the air holes 302 are opened inside each anti-skid pad 109. A middle section support sleeve 110 is fixed to the outside of the rotating drum 104 at the middle section.

[0038] Through the adsorption mechanism, while the arc plate 108 applies pulling force to the side of the protective film, the protective film can be closely attached to the surface of the anti-slip pad 109 by increasing the air pressure difference, thereby increasing the friction between the protective film and the anti-slip pad 109. Therefore, when the two sides of the protective film are pulled, the relative sliding between the arc plate 108 and the protective film can be reduced, thereby improving the pulling effect, and fully eliminating the longitudinal wrinkles on the protective film.

[0039] Furthermore, a first baffle plate 309 and a second baffle plate 310 are fixed to one end of the push-pull rod 305, and the first baffle plate 309 and the second baffle plate 310 are respectively located on both sides of the air pumping piston plate 307, and the air pumping piston plate 307 is slidably connected to the outer side of the push-pull rod 305, and a protective spring 311 is connected between the air pumping piston plate 307 and the first baffle plate 309;

[0040] One end of the air pumping piston plate 307 is elastically connected to the first baffle plate 309 through a protective spring 311. As the push-pull rod 305, the air pumping piston plate 307 and the slider 107 move relative to each other, when the air pressure difference in the space at both ends of the air pumping piston plate 307 inside the air pumping chamber 304 reaches a certain value, the speed of the air pumping piston plate 307 moving relative to the right will be slowed down, while the relative movement speed of the push-pull rod 305 remains unchanged. Therefore, the air pumping piston plate 307 will compress the protective spring 311, which plays a buffering role and reduces the speed of the pressure drop in the space at the left end of the air pumping chamber 304, thereby maintaining the negative pressure inside the air pumping chamber 304 and the arc cavity 301 within a certain range to prevent the external atmospheric pressure from breaking the protective film due to excessive negative pressure.

[0041] Further, the driving mechanism includes a main motor 401 installed on one side of one of the fourth side plates 101, two driving pulleys 404 rotatably connected to one side of the fourth side plate 101, and two driven pulleys 403 fixed to one end of the two rotating shafts 103, the two driven pulleys 403 are respectively connected to the two driving pulleys 404 through a synchronous belt 406, one end of the two driving pulleys 404 is fixed with a worm gear 405, and the driving end of the main motor 401 is fixed with a worm 402 that can mesh with the two worm gears 405;

[0042] The driving mechanism is used to drive the two rotating drums 104 of the two anti-wrinkle mechanisms to rotate in opposite directions at the same speed, so that the upper and lower protective films can be pulled to move at the same speed, so that the protective films on both sides can be evenly attached to the two side surfaces of the circuit board substrate, thereby improving the production quality of the circuit board.

[0043] Furthermore, four guide rollers 12 are symmetrically connected to the two sides of the fourth side plate 101, the two guide rollers 12 located at the top are aligned with the upper drum 104, and the two guide rollers 12 located at the bottom are aligned with the lower drum 104. Under the guiding effect of the guide rollers 12 on both sides, the protective film can be in contact with the outer side of the drum 104 over a larger area (such as Figure 3 The protective film is pulled more smoothly and the traction is improved to prevent slipping.

[0044] Furthermore, the pressing mechanism includes two first side plates 2 fixed on the upper side of the bottom plate 1 and located on one side of the two fourth side plates 101, two hot pressing rollers 3 are rotatably connected between the two first side plates 2, one end of the two hot pressing rollers 3 are fixed with mutually meshing synchronous gears 5, a hot pressing traction motor 4 is installed on one side of one of the first side plates 2, and the driving end of the hot pressing traction motor 4 is fixedly connected to one end of one of the hot pressing rollers 3;

[0045] When the circuit board substrate and the two protective films pass between the two hot pressing rollers 3 of the laminating mechanism, the two hot pressing rollers 3 can heat and pressurize the three, so that the two protective films are attached to both sides of the circuit board substrate.

[0046] Further, two second side plates 6 are fixed to one end of the upper side of the bottom plate 1 close to the fourth side plate 101, and two third side plates 9 are fixed to one end of the upper side of the bottom plate 1 close to the first side plate 2, two protective film unloading rollers 8 and a flexible circuit board unloading roller 7 are rotatably connected between the two second side plates 6, the flexible circuit board unloading roller 7 is located in the middle of the two protective film unloading rollers 8, a winding roller 10 is rotatably connected between the two third side plates 9, and a winding motor 11 for driving the winding roller 10 to rotate is installed on one side of one of the third side plates 9;

[0047] The winding motor 11 drives the winding roller 10 to rotate, which can assist in winding the pressed circuit board on the outside of the winding roller 10. The two protective film unwinding rollers 8 are used to release the protective film, and the flexible circuit board unwinding roller 7 is used to release the flexible circuit board substrate.

[0048] Working principle: When in use, the circuit board substrate is wound around the outside of the flexible circuit board unwinding roller 7, and the two protective films used for laminating on both sides of the circuit board base layer are wound around the outside of the two protective film unwinding rollers 8. When the circuit board substrate and the two protective films pass between the two hot pressing rollers 3 of the laminating mechanism, the two hot pressing rollers 3 can heat and pressurize the three, so that the two protective films are laminated on both sides of the circuit board substrate. The hot pressing traction motor 4 of the laminating mechanism drives the corresponding hot pressing roller 3 to rotate, and this hot pressing roller 3 drives a synchronous gear 5 at its end to rotate. This synchronous gear 5 drives another synchronous gear 5 to rotate in the opposite direction through the teeth, thereby driving the other hot pressing roller 3 to rotate in the opposite direction. The two hot pressing rollers 3 rotate at the same speed in opposite directions, and the circuit board substrate and the two protective films can be pulled to one end in turn, so that the two protective films can be evenly laminated on both sides of the circuit board substrate, completing the film laminating process. At the same time, the winding motor 11 drives the winding roller 10 to rotate, and the winding roller 10 can roll up the laminated circuit board;

[0049] Before the two protective films are attached to the circuit board substrate, they need to pass through the outside of the rotating drum 104 of the two anti-wrinkle mechanisms. The main motor 401 of the driving mechanism drives the worm 402 to rotate, and the worm 402 drives the two worm wheels 405 to rotate at a constant speed in the opposite direction. The two worm wheels 405 respectively drive the two driving pulleys 404 to rotate at a constant speed in the opposite direction. The two driving pulleys 404 drive the two driven pulleys 403 to rotate at a constant speed in the opposite direction through the synchronous belt 406. The two driven pulleys 403 respectively drive the two rotating shafts 103 of the two anti-wrinkle mechanisms to rotate at a constant speed in the opposite direction. The two rotating shafts 103 respectively drive the two rotating drums 104 to rotate at a constant speed in the opposite direction.

[0050] When the rotating drum 104 of the anti-wrinkle mechanism rotates (refer to the movement of the anti-wrinkle mechanism above, the movement of the anti-wrinkle mechanism below is the same), the protective film wrapped around its outer side is affected by the friction force and can move to one end. Since the fixed rod 102 and one of the fourth side plates 101 are fixed and do not rotate, the fixed rod 102 and the rotating drum 104 will rotate relative to each other. The multiple arc plates 108 at both ends of the rotating drum 104 contact the two side edges of the protective film, and the middle support sleeve 108 at the middle position of the rotating drum 104 is in contact with the two side edges of the protective film. 10 contacts the middle position of the protective film, each arc plate 108 is fixed to one end of the corresponding slider 107, when the rotating drum 104 drives the multiple sliders 107 to rotate, each slider 107 drives the roller 202 in the transmission mechanism to slide along the inner side of the guide groove structure, because the separation guide groove 203 is facing the moving direction of the protective film, and the two transposition inclined grooves 205 are respectively located at the uppermost and lowermost sides of the guide groove column 201, so when each roller 202 slides from the inner side of the merging guide groove 204 into the upper transposition inclined groove When the roller 202 is in the inner side of the groove 205, under the guiding action of the upper transposition inclined groove 205, the roller 202 can be guided to the inner side of the separation guide groove 203, so that the roller 202 slides into the inner side of the separation guide groove 203. Since the separation guide groove 203 is far away from the middle section of the fixed rod 102, and the merging guide groove 204 is close to the middle section of the fixed rod 102, when the roller 202 moves from the inner side of the merging guide groove 204 to the inner side of the separation guide groove 203, it will drive the slider 107 to slide along the inner side of the slide groove 105. The roller 202 moves toward the end of the drum 104, so that the arc plates 108 at both ends move in the opposite direction at a constant speed, so that the arc plates 108 at both ends move away from each other. As the drum 104 continues to rotate, when the roller 202 slides from the inner side of the separation guide groove 203 to the inner side of the transposition inclined groove 205 at the lower side, it will be guided to slide into the inner side of the merging guide groove 204 again. In this process, the slider 107 that has moved away moves in the opposite direction to reset, thereby driving the arc plates 108 at both ends to close, so as to facilitate the next cycle.

[0051] Through the action of the transmission mechanism, the multiple curved plates 108 located on the side of the rotating drum 104 close to the pressing mechanism can be separated, and the multiple curved plates 108 located on the other side of the rotating drum 104 can be closed. Therefore, when the rotating drum 104 pulls the protective film to move, the multiple curved plates 108 at both ends of the rotating drum 104 and close to the pressing mechanism can apply opposite forces from both sides of the protective film, so that the protective film can be pulled horizontally, thereby preventing the protective film from being wrinkled longitudinally during the pulling process. Therefore, the flatness of the protective film during pulling can be ensured, thereby improving the adhesion between the protective film and the circuit board substrate, avoiding the generation of bubbles between the protective film and the circuit board substrate, and greatly improving the film lamination quality;

[0052] Under the guidance of the guide groove structure, each slider 107 is driven to move toward the end of the rotating drum 104. At the same time, the slider 107 can slide on the outside of the guide rod 106 at the corresponding position. One end of the push-pull rod 305 in the adsorption mechanism corresponding to the slider 107 is fixed to the outside of the guide rod 106 through the fixing plate 306. When the sliders 107 at both ends are away from each other, the suction piston plate 307 in the adsorption mechanism will move rightward relative to the suction chamber 304 (such as Figure 8 As shown), negative pressure is formed in the space at the left end of the air extraction chamber 304, and the air inside the arc-shaped chamber 301 is sucked into the space at the left end of the air extraction chamber 304 through the airway 303 and the connecting air pipe 308. Since the anti-skid pad 109 on one side of the arc-shaped plate 108 is tightly fitted with one side of the protective film, the external air will not enter the inner side of the arc-shaped chamber 301 through the air hole 302, so negative pressure is also formed in the inner side of the arc-shaped chamber 301, thereby producing an adsorption effect on the protective film, increasing the pressure on the surface of the protective film and the anti-skid pad 109, thereby increasing the friction between the anti-skid pad 109 and the protective film, so that when the two sides of the protective film are pulled, the relative sliding between the arc-shaped plate 108 and the protective film can be reduced, thereby improving the pulling effect, thereby fully eliminating The longitudinal folds on the protective film, one end of the air pumping piston plate 307 is elastically connected to the first baffle plate 309 through the protective spring 311. With the relative movement between the push-pull rod 305, the air pumping piston plate 307 and the slider 107, when the air pressure difference between the two ends of the air pumping piston plate 307 inside the air pumping chamber 304 reaches a certain value, the speed of the relative movement of the air pumping piston plate 307 to the right will be slowed down, while the relative movement speed of the push-pull rod 305 will not change, so that the air pumping piston plate 307 will compress the protective spring 311, which plays a buffering role and reduces the speed of the pressure drop in the space at the left end of the air pumping chamber 304, so that the negative pressure inside the air pumping chamber 304 and the arc cavity 301 is maintained within a certain range, avoiding excessive negative pressure that causes the external atmospheric pressure to break the protective film;

[0053] As the protective film is pulled by the rotating drum 104 and moves, when the protective film is separated from the rotating drum 104, the protective film will be separated from the surface of the anti-slip pad 109, so that the external air enters the arc cavity 301 through multiple air holes 302 and multiple air holes of the pad, so that the arc cavity 301 is balanced with the external air pressure, thereby losing the adsorption force on the protective film, so that the protective film is smoothly separated from the outside of the rotating drum 104. After the protective film is separated from the rotating drum 104, it can be pressed onto the surface of the circuit board substrate through the pressing mechanism.
