Description

Technical Field

[0001] The invention relates to the technical field of FPC processing, and in particular to a production and processing device for FPC. Background Art

[0002] Flexible Printed Circuit (FPC) is a highly reliable and extremely flexible die-cut circuit made of polyimide or polyester film. It can be freely bent, folded, and wound, and can be moved and stretched in three-dimensional space, thereby achieving the integration of component assembly and wire connection. FPC can greatly reduce the size of electronic products, and meet the needs of electronic products to develop in the direction of high density, miniaturization, and high reliability; therefore, FPC is widely used in aerospace, military, mobile, communication, automotive and other fields.

[0003] One of the main processes in the existing FPC production is development-etching-stripping. Development is to remove the covering film of the non-circuit area on the copper foil flexible circuit board to expose the covering film of the circuit area, and then etch the copper foil in the non-circuit area with an etching solution to react and remove the unnecessary copper, and then process it into a circuit with a predetermined track on the flexible circuit board, and finally strip off the covering film and clean and dry the etched flexible circuit board.

[0004] However, this processing method causes the copper foil in the FPC to react chemically with the etching solution during etching, thereby generating chemical waste. If it is discharged directly, it will cause heavy metal pollution and cause the metal in the chemical waste to be wasted. However, if the metal in the chemical waste is recovered, it will cost a high cost to recycle and treat the pollution emissions, thereby increasing the production cost. Summary of the invention

[0038] Reference Figures 1 to 5 The present invention provides a production and processing equipment for FPC, comprising:

[0039] frame;

[0040] The adhesive protective film assembly is installed on the frame, including a medium-adhesive protective film assembly for setting a medium-adhesive protective film 13 on the copper foil and a low-adhesive protective film assembly for setting a low-adhesive protective film 14 on the FPC;

[0041] A circular knife assembly is installed on the frame, comprising a first circular knife assembly for die-cutting the copper foil 10 and a second circular knife assembly for die-cutting the FPC;

[0042] A thermosetting adhesive film assembly is installed on the frame, comprising a first thermosetting adhesive film assembly and a second thermosetting adhesive film assembly for attaching thermosetting adhesive films to both sides of the copper foil 10;

[0043] a film tearing assembly, mounted on the frame, comprising a medium-viscosity film tearing assembly for tearing off the medium-viscosity protective film 13 and a low-viscosity film tearing assembly for tearing off the low-viscosity protective film 14, so as to remove waste generated by the circular knife assembly; and

[0044] A transport assembly is installed on the frame, and is used to transport the FPC in sequence to the medium-viscosity protective film assembly, the first circular knife assembly, the first thermosetting adhesive film assembly, the medium-viscosity tearing film assembly, the low-viscosity protective film assembly, the second circular knife assembly, the second thermosetting adhesive film assembly, and the low-viscosity tearing film assembly for processing.

[0045] The technical solution of the present invention installs a transport assembly on a frame, thereby transporting the FPC to the medium-viscosity protective film assembly, the first circular knife assembly, the first thermosetting adhesive film assembly, the medium-viscosity tearing film assembly, the low-viscosity protective film assembly, the second circular knife assembly, the second thermosetting adhesive film assembly and the low-viscosity tearing film assembly in sequence for processing, wherein the copper foil 10 is cut into strips by the first circular knife assembly, and the FPC is punched by the second circular knife assembly, thereby peeling off the copper foil 10 in the non-circuit area and retaining the copper foil 10 in the circuit area, and finally, the waste generated after cutting by the first circular knife assembly and the second circular knife assembly is recovered by the medium-viscosity tearing film assembly and the low-viscosity tearing film assembly for reproduction, and the recycling cost is low, thereby reducing the production cost.

[0046] It can be understood that compared to processing flexible circuit boards with chemical solutions, if the copper after chemical corrosion is not recovered, the chemical solutions will cause greater environmental pollution. When the copper after chemical corrosion needs to be recovered, it is necessary to recover it through chemical reactions, which will produce new chemical pollutants. However, if chemical pollution is to be solved, a higher treatment cost is required, which will increase the production cost. In this application, it is directly cut by a circular knife and then recovered through a medium-viscosity protective film and a low-viscosity protective film. The pollution caused in the production process is very small. Compared with chemical processing, it reduces environmental pollution and increases the production cost.

[0047] It should be noted that, in one embodiment, the first circular knife cutting only cuts the copper foil 10, and the second circular knife cutting cuts the copper foil 10 layers, the first thermosetting adhesive layer and the second thermosetting adhesive layer; of course, in another embodiment, the first circular knife assembly can be divided into two groups, one group is only for cutting the copper foil 10 layers, and the other group can cut the copper foil 10 layers and the first thermosetting adhesive layer at the same time, which can be adaptively adjusted according to the production and processing of FPC.

[0048] In this embodiment, the transport component includes a transport motor, a driving roller 21 and a driven roller 22. The transport motor is installed on the frame. The driving roller 21 is connected to the output shaft of the transport motor. The driving roller 21 is connected to the driven roller 22. The transport motor drives the driving roller 21 to rotate, thereby driving the driven roller 22 to rotate, so as to drive the FPC and the adhesive protective film to move. Of course, in other embodiments, the transport component can also be a transport motor, a driving wheel, a driven wheel and a transmission belt. The transport motor is installed on the frame. The output shaft of the transport motor is connected to the driving wheel. The transmission belt is sleeved on the driving wheel and the driven wheel. The FPC is placed on the transmission belt. The driving wheel is driven by the transport motor to rotate, thereby driving the transmission belt and the driven wheel to move, thereby driving the FPC to move, and thereby moving the FPC to different processing positions.

[0049] Specifically, the medium-viscosity protective film assembly includes a medium-viscosity protective film motor and a medium-viscosity protective film roller 31, and the low-viscosity protective film assembly includes a low-viscosity protective film motor and a low-viscosity protective film roller 33. The medium-viscosity protective film motor and the low-viscosity protective film motor are both installed on the frame, and the medium-viscosity protective film roller 31 and the low-viscosity protective film roller 33 are respectively connected to the output shaft of the medium-viscosity protective film motor and the output shaft of the low-viscosity protective film motor; the medium-viscosity film tearing assembly includes a medium-viscosity film tearing motor and a medium-viscosity film tearing roller 51, and the low-viscosity protective film assembly includes a low-viscosity film tearing motor and a low-viscosity film tearing roller 52. The medium-viscosity film tearing motor and the low-viscosity film tearing motor are both installed on the frame, and the medium-viscosity film tearing roller 51 and the low-viscosity film tearing roller 52 are respectively connected to the output shaft of the medium-viscosity film tearing motor and the output shaft of the low-viscosity film tearing motor, and are used to tear off the medium-viscosity protective film 13 and the low-viscosity protective film 14.

[0050] It should be noted that the medium-viscosity protective film 13 and the low-viscosity protective film 14 both have two functions. One is to recycle the waste generated after the first and second round knife cutting by adhering to it; the other is to isolate the FPC from the transportation component by the medium-viscosity protective film 13 and the low-viscosity protective film 14. Because, when the transportation component drives the FPC to move, there will inevitably be a certain amount of friction, which will then wear the copper foil 10 or the first thermosetting adhesive film 11 or the second thermosetting adhesive film 12, thereby reducing the performance of the FPC, and also preventing the copper waste generated after the first and second round knife cutting from scratching the driven roller 22, which will also affect the production equipment. Therefore, by setting the medium-viscosity protective film 13 and the low-viscosity protective film 14, it can play a good role of protection and recycling. The medium-viscosity protective film 13 and the low-viscosity protective film 14 can be one of PET, PE, and OPP materials, which are cheap, thereby reducing the production and processing costs of FPC, and are suitable for large-scale promotion.

[0051] Of course, in other embodiments, a controller and a robotic arm can be set up, and the controller can be used to control the movement of the robotic arm to stick the medium-viscosity protective film 13 and the low-viscosity protective film 14 onto the FPC, and the medium-viscosity protective film 13 and the low-viscosity protective film 14 can be pressed onto the FPC by the robotic arm, and then when the copper foil 10 is moved by the transport roller, the medium-viscosity protective film 13 and the low-viscosity protective film 14 are continuously adhered to the FPC by continuous pressing by the robotic arm. Of course, the medium-viscosity protective film 13 and the low-viscosity protective film 14 on the FPC can also be torn off by the robotic arm.

[0052] Furthermore, a release film is further provided on the side of the thermosetting adhesive film facing the copper foil 10, the thermosetting adhesive film includes a first thermosetting adhesive film 11 and a second thermosetting adhesive film 12, the release film includes a first release film 15 and a second release film 16, the thermosetting adhesive film assembly includes a first thermosetting adhesive film 11 assembly and a second thermosetting adhesive film 12 assembly, the first thermosetting adhesive film 11 assembly includes a first release motor, a first release roller 35, a first thermosetting adhesive motor and a first thermosetting adhesive roller 32, the second thermosetting adhesive film 12 assembly includes a second release motor, a second release roller 36, a second thermosetting adhesive The first release motor, the first thermosetting adhesive motor, the second release motor and the second thermosetting adhesive motor are all installed on the frame, and the first release roller 35, the first thermosetting adhesive roller 32, the second release roller 36 and the second thermosetting adhesive roller 34 are respectively connected to the output shafts of the first release motor, the first thermosetting adhesive motor, the second release motor and the second thermosetting adhesive motor to respectively stick the first thermosetting adhesive film 11 and the second thermosetting adhesive film 12 to both sides of the copper foil 10.

[0053] Before the first thermosetting adhesive film 11 and the second thermosetting adhesive film 12 are adhered to the copper foil 10 , a release film can be provided to protect the first thermosetting adhesive film 11 from being exposed to impurities in the air, which may reduce the adhesion effect.

[0054] Preferably, the thermosetting adhesive film assembly also includes a heating roller installed on the frame, and the heating roller includes a first heating roller 61 and a second heating roller 63, so that when the first thermosetting adhesive film 11 and the second thermosetting adhesive film 12 are adhered to the copper foil 10, a heating treatment is performed respectively. Thermosetting hot melt adhesive film (English name: Hot Glue) is a plastic adhesive, and its physical state changes with temperature changes within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless and is an environmentally friendly chemical product; therefore, by heating the first thermosetting adhesive film 11 and / or the second thermosetting adhesive film 12, the bonding effect of the first thermosetting adhesive film 11 and the second thermosetting adhesive film 12 and the copper foil 10 is improved.

[0055] Two first heating rollers 61 and second heating rollers 63 may be provided and located on both sides of the FPC respectively to improve the heating effect. Of course, in other embodiments, a heating block may be directly installed on the frame to heat the FPC by providing the heating block.

[0056] Furthermore, the FPC production and processing equipment also includes a pressure roller installed on the frame, and the pressure roller includes a first pressure roller 62 and a second pressure roller 64; it can be understood that when tearing off the medium-viscosity protective layer and the low-viscosity protective layer, if the waste generated during the first circular knife assembly and the second circular knife assembly shearing cannot be tightly bonded to the medium-viscosity protective layer and the low-viscosity protective layer, the waste will still remain on the FPC. Therefore, the first pressure roller 62 and the second pressure roller 64 are respectively used to pressurize the medium-viscosity protective film 13 and the FPC, and the low-viscosity protective film 14 and the FPC before the first circular knife assembly cutting and the second circular knife assembly cutting, so as to increase the tightness of the connection, thereby improving the recovery rate of the tube. At the same time, the remaining copper waste will also affect the product quality, so the pressure roller can also play a role in improving the product quality; at the same time, the first pressure roller 62 and the second pressure roller 64 can also improve the bonding effect between the first thermosetting adhesive film 11, the copper foil 10 and the second thermosetting adhesive film 12.

[0057] Preferably, in this embodiment, the pressure roller and the heating roller are the same, that is, the pressure roller can achieve both pressure and heating, thereby reducing the number of parts of the production equipment and reducing the volume of the production and processing equipment; of course, in other embodiments, it can also be through a controller and a stamping plate electrically connected to the controller, and there are two stamping plates, which are respectively located on both sides of the FPC, and the controller controls the movement and downward pressure of the stamping plate to pressurize the FPC.

[0058] Specifically, the circular knife assembly includes a first circular knife assembly and a second circular knife assembly, the first circular knife assembly includes a first circular knife motor and a first circular knife roller 41 installed on the frame, the first circular knife roller 41 is transmission connected to the output shaft of the first circular knife motor, and the first circular knife roller 41 is provided with at least one blade; the second circular knife assembly includes a second circular knife motor and a second circular knife roller 42 installed on the frame, the second circular knife roller 42 is transmission connected to the output shaft of the second circular knife motor, and the second circular knife roller 42 is provided with at least one blade, wherein the first circular knife assembly specifically performs die-cutting processing on the copper foil circuit.

[0059] Furthermore, in the present embodiment, the circular knife assembly also includes a third circular knife assembly, which includes a third circular knife motor and a third circular knife roller 43 installed on the frame. The third circular knife roller 43 is drivingly connected to the output shaft of the third circular knife motor and is used to die-cut the second thermosetting adhesive film 12. Accordingly, a third heating roller 65 and a third pressure roller 66 are also provided at this time to heat and pressurize the FPC.

[0060] In the process of producing and processing FPC, if only one first circular knife roller 41 or second circular knife roller 42 is set, it may be necessary to set a larger-sized knife roller, which requires a larger space to place the knife roller, and thus causes the equipment to be larger. Therefore, in the present embodiment, the first circular knife roller 41 and the second circular knife roller 42 are respectively provided with a plurality of them, wherein the first circular knife roller 41 is provided with two groups, each group is provided with a plurality of first circular knife rollers 41, and the intervals between the plurality of first circular knife rollers 41 in each group are equal to the circumference of the first circular knife roller 41, so that the blades between the two adjacent first circular knife rollers 41 are seamlessly connected, thereby realizing continuous shearing. Similarly, the second circular knife roller 42 is also provided with a plurality of them, and the adjacent two first circular knife rollers 41 are provided with a plurality of them. The distance between the two circular knife rollers 42 is equal to the circumference of the second circular knife roller 42, so that the blades between the two adjacent second circular knife rollers 42 are seamlessly connected, thereby realizing continuous cutting; of course, in other embodiments, if only punching holes in the FPC is required, or continuous cutting is not required, there is no need to require that the distance between the two adjacent knife rollers is equal to the circumference of the knife rollers; of course, in other embodiments, the first circular knife roller 41 can be distributed in the middle of the copper foil 10 and the medium-viscosity protective film 13, so that the first circular knife roller 41 simultaneously shears the copper foil 10 and the medium-viscosity protective film 13, and when the first circular knife roller 41 has completed shearing the medium-viscosity protective film 13 alone, the medium-viscosity protective film 13 is pasted to the copper foil 10.

[0061] The circular knife assembly also includes a fourth circular knife assembly, which includes a fourth circular knife motor installed on the frame and a fourth circular knife roller connected to the output shaft of the fourth circular knife motor to drive the motor. The large FPC is die-cut by the fourth circular knife roller to be processed into a mature small FPC, so that a large number of FPCs can be obtained in one production process, thereby improving the production and processing efficiency.

[0062] Furthermore, the first assembly is used to die-cut the copper foil, the second and fourth circular knife assemblies are used to die-cut the flexible circuit board, and the third circular knife assembly is used to die-cut the second thermosetting adhesive film; the die-cutting process can be cutting strips, punching holes, digging grooves, etc., which can be changed according to the processing requirements of the flexible circuit board.

[0063] The production and processing equipment of the FPC is provided with an inkjet printer to set an identification code for the FPC. The identification code is sprayed by the inkjet printer, thereby facilitating subsequent packaging identification of the FPC.

[0064] Specifically, the production process of FPC is as follows: the copper foil 10 is transported to the production and processing line through the transport component, the medium-viscosity protective film 13 is pasted on one side of the copper foil 10, and then the circuit of the copper foil 10 is die-cut through the first circular knife component. Further, the first thermosetting adhesive film 11 is pasted on the side of the copper foil 10 away from the medium-viscosity protective film 13, and the copper foil 10, the first thermosetting adhesive film 11 and the medium-viscosity protective film 13 are heated and pressurized. At this time, the copper waste after the die-cutting treatment by the first circular knife component will adhere to the medium-viscosity protective film 13, and then the medium-viscosity protective layer will be torn off, thereby removing the waste generated after the first circular knife component cutting treatment; further, on the side of the copper foil 10 away from the first A second thermosetting adhesive film 12 is adhered to one side of the thermosetting adhesive film 11, and a low-viscosity protective film 14 is adhered to the side of the first thermosetting adhesive film 11 away from the copper foil 10, and then the FPC is subjected to a second round knife cutting; the second round knife cutting is mainly to die-cut the FPC, and after the die-cutting of the second round knife assembly is completed, the low-viscosity protective layer is torn off to remove the waste generated after punching the FPC; before the second thermosetting adhesive film 12 is adhered to the copper foil 10 layer, the second thermosetting adhesive film 12 is subjected to a third round knife assembly die-cutting treatment, and at the end of the production process, the FPC is die-cut by the fourth round knife assembly to cut the large FPC into multiple small mature FPCs.

[0065] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
