Description

Technical Field

[0001] This invention relates to the field of printed circuit manufacturing equipment technology, and in particular to a manufacturing equipment for adding a non-metallic protective layer to printed circuits. Background Technology

[0002] Currently, most laminating machines on the market only have a film-tearing structure or a film-rolling structure. Patent application CN217428448U discloses a film-tearing mechanism for an FPC laminating machine and an FPC laminating machine. The film-tearing mechanism includes a feeding device, a film lifting device, and a film peeling device. However, it only has the function of tearing film (i.e., sheet film) and does not have the function of rolling film. But the market needs a laminating machine that has both of these functions. The key to making a laminating machine with both functions is that it must be compatible with both sheet film structure and roll film structure. Summary of the Invention

[0003] To address the aforementioned shortcomings, the present invention aims to propose a dual-purpose structure for FPC laminating machines (both sheet and roll), as well as an FPC laminating machine, thereby solving the problems of traditional sheet and roll lamination requiring different machines, occupying more space, and incurring higher equipment costs.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A dual-purpose roll structure for an FPC laminating machine includes a film hopper, a film loading robot, a film lifting assembly, a film peeling assembly, a film pulling assembly, a wire mesh platform, a roll feeding assembly, a feeding guide roller assembly, a roll cutting assembly, and a roll bottom paper take-up assembly;

[0006] The membrane hopper is used to supply sheet membrane to the upward membrane robot arm;

[0007] The upper membrane robotic arm is responsible for taking membrane sheets from the membrane hopper and sending them to the membrane stripping assembly;

[0008] The film-lifting assembly is used to lift one corner of the film, separating the edge portion of the film from the backing paper;

[0009] The film peeling assembly is used to fix the backing paper when the film is lifted. When the film is pulled, the film peeling assembly is responsible for clamping the backing paper and working together with the film pulling assembly to completely separate the film and the backing paper.

[0010] The film pulling assembly, in conjunction with the film peeling assembly, completely separates the film from the backing paper and pulls the film onto the wire mesh platform;

[0011] The roll unloading assembly is used to place and fix the roll film;

[0012] The roll cutting assembly is used to cut the roll film;

[0013] The roll bottom paper take-up assembly is used to make the roll film travel along a specified trajectory and provide power for winding the bottom paper.

[0014] Furthermore, a vertical plate is fixed to one side of the film hopper, a magnetic powder motor is fixed to the upper end of the vertical plate, an expansion shaft is fixed to the output end of the magnetic powder motor, and a roll of film is wound on the expansion shaft.

[0015] Furthermore, the roll bottom paper take-up assembly includes five rotating rollers that guide the movement trajectory of the bottom paper and a motor that controls the rotation of each rotating roller.

[0016] Multiple rotating rollers are fixed at staggered positions below the wire mesh platform of the laminating machine, and the base paper moves along the rotating rollers.

[0017] Furthermore, the film-forming assembly includes a second rotating roller, a support base, an X-axis slide rail, a Y-axis slide rail, and a Z-axis slide rail. The support base is provided with an X-axis slide rail, the Y-axis slide rail is slidably connected to the X-axis slide rail, the Z-axis slide rail is slidably connected to the Y-axis slide rail, and a Z-axis motor is fixed on the Z-axis slide rail. One of the film-forming roller or a cutting plate is detachably fixed below the Z-axis motor. When the cutting plate is fixed below the Z-axis motor, it constitutes part of the roll material cutting assembly.

[0018] The second rotating roller is positioned along the Y-axis at one end of the film-forming assembly facing the film hopper.

[0019] Furthermore, the roll material cutting assembly also includes a long block-shaped cutting group and a cutting blade. A long block-shaped cutting group that can move up and down is provided directly below the cutting pressure plate. The side of the cutting group facing the cutting pressure plate has a groove. A cutting blade that can move along the groove is provided in the groove, and the blade tip of the cutting blade protrudes outward from the groove.

[0020] The cutting assembly is located on the machine body below the gap between the wire mesh platform and the film peeling assembly.

[0021] Furthermore, the film hopper includes a feeding base plate, a fixing plate, a lifting rod, and a lifting motor. The upper end of the motor shaft of the lifting motor and the upper end of the lifting rod are connected to the lower part of the feeding base plate. The lower end of the lifting rod is connected to the fixing plate, and the motor is fixed to the lower end of the fixing plate.

[0022] Furthermore, the film-feeding robot includes multiple vacuum suction heads, a connecting arm, and an X-axis slide rail II. The multiple vacuum suction heads are arranged above the material feeding base plate and fixed to one end of the connecting arm. The other end of the connecting arm is slidably connected to the X-axis slide rail II, which faces the film-peeling assembly.

[0023] Furthermore, the film peeling assembly includes a film peeling machine base, a gyratory pressing roller, a first gyratory arm, a second gyratory arm, an upper clamping roller, a lower clamping roller, a rotary cylinder, and a vacuum device. The vacuum device is located below the horizontal worktable of the film peeling machine base. Vacuum holes are provided on the horizontal worktable. A lower clamping roller is fixed at one end of the horizontal worktable facing the wire mesh platform. An upper clamping roller that can rotate and swing around the lower clamping roller is located below the end of the lower clamping roller facing the wire mesh platform. The upper clamping roller is close to the lower clamping roller. The upper clamping roller is connected to the rotary cylinder through the first gyratory arm.

[0024] The gyratory pressing roller is connected to one end of the second gyratory arm, and the other end of the second gyratory arm is hinged to the power unit on the side wall of the film peeling assembly. The second gyratory arm can drive the gyratory pressing roller to swing and press against the horizontal worktable.

[0025] Furthermore, the film-stretching assembly includes a wire mesh platform and a film-stretching mechanism, the film-stretching mechanism being able to reciprocate relative to the film-peeling assembly along the wire mesh platform.

[0026] An FPC laminating machine includes the roll-to-sheet structure described in any one of the above claims.

[0027] The technical solution provided by this invention may include the following beneficial effects:

[0028] The FPC laminating machine of the present invention integrates both sheet film structure and roll film structure. Sheet film and roll film can be switched on one machine, avoiding the disadvantages of traditional sheet film and roll film using different machines, which occupy more space and have higher equipment costs.

[0041] An FPC laminating machine includes a roll-to-sheet structure, which includes a film hopper 1, a film loading robot 2, a film lifting assembly 3, a film peeling assembly 4, a film pulling assembly 5, a roll unloading assembly 6, a roll cutting assembly 72 pieces 7, and a roll bottom paper take-up assembly 8.

[0042] The membrane hopper 1 is used to supply sheet membrane to the upward membrane robot arm 2;

[0043] The upper membrane robot 2 is responsible for taking membrane sheets from the membrane hopper 1 and sending them to the membrane stripping assembly 4;

[0044] The film-lifting assembly 3 is used to adhere one corner of the film, so that the edge portion of the film is separated from the backing paper;

[0045] The film peeling component 4 is used to fix the backing paper when lifting the film. When pulling the film, the film peeling component 4 is responsible for clamping the backing paper and working together with the film pulling component 5 to completely separate the film and the backing paper.

[0046] The film pulling assembly 5, in conjunction with the film peeling assembly 4, completely separates the film from the backing paper and pulls the film onto the wire mesh platform 51.

[0047] The roll unloading assembly 6 is used to place and fix the roll film;

[0048] The roll cutting assembly 72 pieces 7 is used to cut the roll film;

[0049] The roll bottom paper take-up assembly 8 is used to make the roll film travel along a specified trajectory and provide power for taking up the bottom paper.

[0050] Specifically, such as Figure 1-8 As shown, this FPC laminating machine can simultaneously perform two functions: film cutting and film winding. For the film cutting mode, the corresponding structure and working principle are as follows:

[0051] The film hopper 1 includes a feeding base plate 12, a fixing plate, a lifting rod 13 and a lifting motor 11. The upper end of the motor shaft of the lifting motor 11 and the upper end of the lifting rod 13 are connected to the lower part of the feeding base plate 12. The lower end of the lifting rod 13 is connected to the fixing plate, and the lower end of the fixing plate is fixed with the lifting motor 11.

[0052] A stack of films is manually placed onto the feeding base plate 12 of the equipment, and the motor drives the feeding base plate 12 to move up to below the film feeding robot 2.

[0053] The film-feeding robot 2 includes multiple vacuum suction heads 21, a connecting arm 22, and an X-axis slide rail 23. The multiple vacuum suction heads 21 are arranged above the material feeding base plate 12 and fixed to one end of the connecting arm 22. The other end of the connecting arm 22 is slidably connected to the X-axis slide rail 23 of the frame. The X-axis slide rail 23 is opened towards the film-peeling assembly 4.

[0054] Multiple vacuum suction heads 21 move down to the surface of the membrane and adsorb the membrane by vacuum negative pressure, then shake it up and down to separate the unadsorbed membrane (shaking material). Then, the multiple vacuum suction heads 21 drive the membrane to move along the X-axis slide rail towards the membrane assembly 3, and so on.

[0055] The film-forming assembly 3 includes a support base 31, an X-axis slide rail 32, a Y-axis slide rail 33, and a Z-axis slide rail 34. The support base 31 is equipped with an X-axis slide rail. The Y-axis slide rail 33 is slidably connected to the X-axis slide rail. The Z-axis slide rail 34 is slidably connected to the Y-axis slide rail 33. A Z-axis motor 35 is fixed to the Z-axis slide rail 34. A film-forming roller 36 (which needs to be...) is fixed below the Z-axis motor 35. Figure 1-3 Remove the cutting platen and replace it with a film-raising roller.

[0056] The film peeling assembly 4 includes a film peeling machine base 48, a rotary pressure roller 42, a first swing arm 46, a second swing arm 43, an upper clamping roller 45, a lower clamping roller 44, a rotary cylinder 47, and a vacuum device (not shown). The vacuum device is located below the horizontal worktable of the film peeling machine base 48. A vacuum hole 49 is provided on the horizontal worktable. The lower clamping roller 44 is fixed at one end of the horizontal worktable facing the wire mesh platform 51. An upper clamping roller 45, which can rotate and swing around the lower clamping roller 44, is located below the end of the lower clamping roller 44 facing the wire mesh platform 51. The upper clamping roller 45 is close to the lower clamping roller 44. The upper clamping roller 45 is connected to the rotary cylinder 47 through the first swing arm 46.

[0057] The gyratory pressing roller 42 is connected to one end of the second gyratory arm 43, and the other end of the second gyratory arm 43 is hinged to the power device on the side wall of the film peeling assembly 4. The second gyratory arm 43 can drive the gyratory pressing roller 42 to swing and press against the horizontal worktable.

[0058] The film-pulling assembly 5 includes a wire mesh platform 51 and a film-pulling mechanism 52. The specific structure of the film-pulling mechanism 52 is common knowledge in the field. The film-pulling mechanism 52 can reciprocate relative to the film-peeling assembly 4 along the wire mesh platform 51.

[0059] The film is placed on a horizontal worktable by a vacuum suction head 21. The horizontal worktable is fixed by adsorbing the film through a vacuum device below. The pendulum arm 43 can drive the pendulum pressing roller 42 to swing and press the film. At this time, the film lifting roller 36 moves down and rotates to stick one edge of the film, separating the backing paper from the film body while exposing one edge of the backing paper. Then the platform vacuum is turned off, and the film lifting roller 36 moves up along one edge of the film body and drives the film forward. At the same time, the upper clamping roller 45 rotates to the top of the lower clamping roller 44, forming a gap between them. The backing paper is inserted into the gap, and the film lifting roller 36 drives the film body to the forward-moving wire mesh platform 51 to unfold. The film pulling mechanism 52 moves along the wire mesh platform 51 relative to the film peeling assembly 4 and clamps the film body. Then the film pulling mechanism 52 and the wire mesh platform 51 return to their original positions, and this process is repeated.

[0060] For the 64-roll winding mode, the corresponding structure and working principle are as follows:

[0061] like Figure 1-8 As shown, the difference from the sheet-film mode is that, in the machine reset state, firstly... Figure 4 The film-raising roller 36 below the Z-axis motor 35 is removed and replaced with a cutting plate 71, forming part of the roll cutting assembly 72 7.

[0062] A vertical plate 61 is fixed on one side of the film hopper 1. A magnetic powder motor 62 is fixed at the upper end of the vertical plate 61. An expansion shaft 63 is fixed at the output end of the magnetic powder motor 62. A roll of film 64 is manually wound on the expansion shaft 63.

[0063] Press the manual switch, and the magnetic powder motor 62 will drive the air shaft to tension and fix the coiled material.

[0064] The roll bottom paper take-up assembly 8 includes 5 rotating rollers 81 that guide the movement trajectory of the film and a rotating roller motor 82 that controls the rotation of each rotating roller 81.

[0065] The second rotating roller 41 is arranged along the Y direction at one end of the film-forming assembly 3 facing the film hopper 1, specifically at one end of the film-forming assembly 3 facing the X-axis slide rail 23. Multiple rotating rollers 81 are staggered and fixed below the screen box platform 51 of the laminating machine, and the roll film moves along the aforementioned rotating rollers.

[0066] First, the roll die is set along the rotating roller 41 to prevent it from becoming loose due to lack of overlap. Then, the film and backing paper of the roll die are peeled off. The backing paper is then wound around the five staggered rotating rollers 81 below the wire mesh platform 51, and then tightened and fixed on the last rotating roller 81. The film is then passed through the gap between the upper clamping roller 45 and the lower clamping roller 44 and extended onto the wire mesh platform 51.

[0067] The roll cutting assembly 72 also includes a long block-shaped cutting assembly 72 and a cutting blade 73. The long block-shaped cutting assembly 72, which can be raised and lowered, is provided directly below the cutting pressure plate 71. The cutting assembly 72 has a groove 74 on the side facing the cutting pressure plate 71. The cutting blade 73, which can move along the groove 74, is provided in the groove 74. The blade tip of the cutting blade 73 protrudes outward from the groove 74.

[0068] The cutting assembly 72 is located on the machine body below the gap between the wire mesh platform 51 and the film peeling assembly 4.

[0069] After the film is placed, the film pulling mechanism 52 is activated to pull the film, and at the same time, the roll bottom paper take-up assembly 8 is activated to drive the bottom paper to move. When the film is pulled to a preset length, the cutting assembly 72 is activated to move upward, and at the same time, the cutting pressure plate 71 moves downward. The two clamp the film together, and the roll bottom paper take-up assembly 8 stops driving the bottom paper to move. Meanwhile, the cutter 73 moves along the groove 74 to cut the film.

[0070] After the membrane is cut, the membrane on the cage platform 51 is removed, all components are put back in place, and the membrane pulling mechanism 52 pulls the membrane again, and so on.

[0071] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
