Description

Technical Field

[0001] This invention relates to the field of false-application technology, specifically to a film-applying device and an FPC false-application machine. Background Technology

[0002] In existing FPC (Flexible Printed Circuit) production technology, one of the processes involves using a film-coating device to coat the semi-finished FPC with a film, which is called a false coating process.

[0003] The film-applying device can only be fed after the dummy-applying process, and then it can be installed on the lower fixture through the material-removing structure. Each process takes a certain amount of time, so continuous production is not possible. In addition, the existing dummy-applying machines all require manual loading and unloading, resulting in low overall work efficiency.

[0004] Therefore, a film application device and an FPC false application machine are proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a film application device and an FPC false application machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A film application device, comprising:

[0008] Mounting bracket, with a film fixing assembly mounted on top of the mounting bracket;

[0009] The movable film application component is installed on the inner wall of the mounting frame and is located directly below the fixed film application component.

[0010] An intermittent drive assembly is mounted on a mounting frame and is used for intermittent material movement. The movable film-applying assembly moves upward to push the material away from the intermittent drive assembly, and then comes into contact with the fixed film-applying assembly for a false-applying process.

[0011] Furthermore, the reinforcing plate is stacked on the FPC and then moved above the movable film-applying assembly by an intermittent drive component. The movable film-applying assembly pushes the reinforcing plate and FPC upward to make contact with the fixed film-applying assembly.

[0012] Furthermore, the active film assembly includes:

[0013] Support base, the support base is installed on the top of the mounting bracket;

[0014] Linear drive assembly, which is mounted on top of the support base;

[0015] A connecting plate is mounted on the telescopic end of the linear drive assembly. A support plate is mounted on the top of the connecting plate, and a lower fixture is connected to the top of the support plate.

[0016] Furthermore, the intermittent drive component:

[0017] Intermittent rotation assembly, which is mounted on the side wall of the mounting bracket;

[0018] The conveyor is movably mounted on the mounting frame, and the output end of the intermittent rotation component is connected to the conveyor.

[0019] Furthermore, the transmitted items include:

[0020] A drive roller is mounted on the side wall of the mounting frame via a bearing, and a set of the drive rollers is coaxially connected to the output end of the intermittent rotation assembly.

[0021] The conveyor belt is installed in the evenly spaced grooves of the drive roller. The intermittent rotation component drives the drive roller to rotate intermittently, and the drive roller drives the conveyor belt to move intermittently. The conveyor belt can intermittently drive the material to move.

[0022] Furthermore, the lower fixture is evenly provided with sliding grooves, and the conveyor belt of the conveyor moves in the sliding grooves. When the conveyor belt of the conveyor rotates to the lower end of the sliding groove, the top of the lower fixture comes into contact with the bottom of the movable film-applying assembly.

[0023] Furthermore, the width of the sliding groove is greater than the width of the conveyor belt of the conveyor, and the side wall of the conveyor does not contact the inner wall of the sliding groove when the conveyor belt of the conveyor moves in the sliding groove, so as to avoid the lower fixture from burning the conveyor after heating.

[0024] The FPC false-applied machine includes the aforementioned film applicator, and further includes: a housing and an intelligent loading and unloading structure;

[0025] The intelligent loading and unloading structure is installed inside the housing and is located above the intermittent drive assembly, enabling automatic loading and unloading of materials.

[0026] Furthermore, the intelligent loading and unloading structure includes:

[0027] X-axis drive unit, the X-axis drive unit is installed inside the top of the housing;

[0028] The Y-axis drive is mounted on the drive end of the X-axis drive.

[0029] A horizontal plate is installed at the output end of the Y-axis drive component.

[0030] The feeding suction component is located at one end of the horizontal plate, at the feeding end of the conveyor component;

[0031] A reciprocating rotating component is installed at the other end of the horizontal plate;

[0032] The feeding suction component is located at the drive end of the reciprocating rotating component.

[0033] Furthermore, the material feeding suction component is located at the material feeding end of the conveyor.

[0034] Furthermore, the side wall of the housing is provided with an operating hole, and the housing is provided with a first limiting plate, a second limiting plate and a third limiting plate at the corresponding positions of the operating hole. The third limiting plate is located at the unloading end of the conveyor, and the first limiting plate and the second limiting plate are located at the loading end of the conveyor.

[0035] Furthermore, the housing is also connected to a tensioning structure for tensioning the transmission component, the tensioning mechanism including:

[0036] Support components are installed at the bottom inside the housing;

[0037] A reset component is mounted on a support component.

[0038] The tensioning roller is movably mounted on the reset component. The top of the tensioning roller contacts the bottom of the transmission component, pushing the transmission component upward to tension it.

[0039] The beneficial effects of this invention are:

[0040] After the film-applying device of this invention performs the dummy application, the intermittent drive component sends the finished FPC product away. At the same time, the original FPC and the reinforcing plate are sent to the upper part of the movable film-applying component for continued feeding. Feeding and dummy application can be carried out simultaneously, enabling continuous production. This invention can automatically load and unload materials through an intelligent loading and unloading structure. In conjunction with the film-applying device, it can perform integrated continuous operation, further improving overall work efficiency. In addition, the tensioning structure tensions the intermittent drive component, ensuring the driving stability of the intermittent drive component and facilitating the accurate movement of the original FPC and the reinforcing plate to the upper part of the movable film-applying component.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] The present invention will be further described below with reference to embodiments.

[0055] Example 1

[0056] like Figure 1-6As shown, to achieve the above objectives, the present invention provides the following technical solution:

[0057] A film application device, comprising:

[0058] Mounting bracket 3, with a film fixing assembly mounted on top of mounting bracket 3;

[0059] The fixed film application assembly includes:

[0060] n-shaped plate 7, n-shaped plate 7 is installed on the top of mounting bracket 3;

[0061] Upper carrier 6, the top of upper carrier 6 is installed inside the top of n-shaped plate 7;

[0062] Upper fixture 5 is installed on the top of the upper carrier 6.

[0063] The movable film application component is installed on the inner wall of the mounting frame 3 and is located directly below the fixed film application component.

[0064] The reinforcing plate is stacked on the FPC and then moved above the movable film-applying assembly by the intermittent drive component. The movable film-applying assembly pushes the reinforcing plate and FPC upward to make contact with the fixed film-applying assembly for sham application.

[0065] The active screen protector components include:

[0066] Support base 27 is mounted on the top of mounting bracket 3;

[0067] Linear drive assembly, which is mounted on top of support 27;

[0068] The linear drive assembly is preferably a rotating assembly 17, and the rotating assembly 17 is a cylinder.

[0069] A connecting plate 14 is mounted on the telescopic end of the linear drive assembly. A support plate 10 is mounted on the top of the connecting plate 14, and a lower fixture 13 is connected to the top of the support plate 10.

[0070] like Figure 1 , 3 As shown in -6 and 9, the intermittent drive component:

[0071] An intermittent rotation assembly is mounted on the side wall of the mounting frame 3; the intermittent rotation assembly is preferably a servo drive assembly 8, which is mounted on the outer side of the mounting frame 3.

[0072] The conveyor is movably mounted on the mounting frame 3, and the output end of the intermittent rotation component is connected to the conveyor.

[0073] The transported items include:

[0074] Drive roller 9 is mounted on the side wall of mounting frame 3 via bearings. A set of drive rollers 9 is coaxially connected to the output end of the intermittent rotation assembly.

[0075] The conveyor belt 11 is installed in the grooves evenly opened in the drive roller 9. The intermittent rotation component drives the drive roller 9 to rotate intermittently, and the drive roller 9 drives the conveyor belt 11 to move intermittently. The conveyor belt 11 can intermittently drive the material to move.

[0076] The lower fixture 13 is evenly provided with sliding grooves 18. The conveyor belt 11 of the conveyor moves in the sliding groove 18. When the conveyor belt 11 of the conveyor rotates to the lower end of the sliding groove 18, the top of the lower fixture 13 is in contact with the bottom of the movable film-applying assembly.

[0077] The width of the conveyor belt 11 of the conveyor is smaller than the width of the sliding hole 18. Preferably, the width of the conveyor belt 11 is 3mm, and the width of the sliding groove 18 is 4mm. When the conveyor belt 11 moves in the sliding groove 18, the side wall of the conveyor does not contact the inner wall of the sliding groove 18, avoiding burns to the conveyor caused by the heated lower fixture 13. At the same time, the movable film-applying assembly cannot directly heat the material at the top of the sliding groove 18. The width of the sliding groove 18 is small enough to reduce the area that cannot be directly heated, ensuring that the movable film-applying assembly has a larger heated area when heated, thereby ensuring the overall heating and avoiding uneven heating of a large area due to the sliding groove 18 not being heated, which would affect the false-applying effect.

[0078] Intermittent drive assembly, installed on mounting frame 3, is used for intermittent material movement. The movable film-applying assembly moves upward to push the material away from the intermittent drive assembly, and then comes into contact with the fixed film-applying assembly for false application.

[0079] In use, the reinforcing plate is on the FPC original. The intermittent drive component of the film-applying device drives the FPC original and the reinforcing plate to move onto the lower fixture 13 of the movable film-applying component. The push component 15 pushes the lower fixture 13 upward through the support plate 10 and the connecting plate 14. The lower fixture 13 pushes the FPC original and the reinforcing plate upward to cooperate with the upper fixture 5 for dummy application. After dummy application is formed, the FPC finished product is obtained. The intermittent drive component sends the FPC finished product away. At the same time, the FPC original and the reinforcing plate are sent to the upper part of the movable film-applying component for continued feeding. Feeding and dummy application can be carried out simultaneously, and continuous production can be carried out.

[0080] Example 2

[0081] like Figure 1-7 As shown, the FPC false-applied machine includes a film-applied device, and also includes: a housing 1 and an intelligent loading and unloading structure;

[0082] The intelligent loading and unloading structure is installed inside the housing 1 and is located above the intermittent drive component, enabling automatic loading and unloading of materials.

[0083] like Figure 1-7 As shown, the intelligent loading and unloading structure includes:

[0084] X-axis drive unit, the X-axis drive unit is installed inside the top of housing 1;

[0085] The Y-axis drive is mounted on the drive end of the X-axis drive.

[0086] Horizontal plate 16 is installed at the output end of the Y-axis drive component;

[0087] The feeding suction component is located at one end of the horizontal plate 16, at the feeding end of the conveyor component;

[0088] A reciprocating rotating component is mounted on the other end of the horizontal plate 16;

[0089] The feeding suction component is located at the drive end of the reciprocating rotating component.

[0090] The material feeding suction device is located at the material feeding end of the conveyor.

[0091] The X-axis drive component is preferably X-axis drive assembly 23;

[0092] Both the X-axis drive assembly 23 and the Y-axis drive assembly 22 can be selected from cylinders or linear motors;

[0093] The Y-axis drive component is preferably Y-axis drive assembly 22, which is installed at the bottom of the sliding block of X-axis drive assembly 23;

[0094] Horizontal plate 16 is installed at the bottom of the telescopic end of the Y-axis drive assembly 22;

[0095] The material suction component is preferably a finished suction cup 4, which is located at one end of the horizontal plate 16 and moves at the discharge end of the conveyor belt 11.

[0096] The reciprocating rotating component is preferably a rotating assembly 17, which is a 180° servo motor or a 180° swing cylinder, and the rotating assembly 17 is installed at the other end of the horizontal plate 16.

[0097] The feeding suction component includes a reinforcing plate suction cup 19 and an FPC suction cup 20. The intermediate plate 21 is fixedly installed at the output end of the rotating assembly 17 of the reciprocating rotating component. The reinforcing plate suction cup 19 and the FPC suction cup 20 are respectively installed at both ends of the intermediate plate 21.

[0098] like Figure 4As shown, the left and right side walls of the housing 1 are provided with operation holes 12. The bottom plate of the inner wall of the housing 1 is provided with a first limiting plate 24, a second limiting plate 25 and a third limiting plate 26 near the three operation holes 12 respectively. The third limiting plate 26 is located at the unloading end of the conveyor, and the first limiting plate 24 and the second limiting plate 25 are located at the loading end of the conveyor.

[0099] The third limiting plate 26 contains finished FPC products;

[0100] The original FPC is placed inside the first limiting plate 24;

[0101] A reinforcing plate is placed inside the second limiting plate 25;

[0102] During use, after the dummy application is completed, the Y-axis drive assembly 22 drives the finished product suction cup 4 downwards, which in turn sucks up the FPC finished product above the conveyor belt 11. Simultaneously, the film application device performs the dummy application, and the Y-axis drive assembly 22 moves upwards. The X-axis drive assembly 23 of the intelligent loading and unloading structure drives the Y-axis drive assembly 22 to move. The Y-axis drive assembly 22 then drives the reinforcing plate suction cup 19 to move above the second limiting plate 25. The Y-axis drive assembly 22 then drives the horizontal plate 16 downwards, the reinforcing plate suction cup 19 sucks up the reinforcing plate, and the FPC suction cup 20 sucks up the original FPC product. Then, the finished product suction cup 4 places the FPC finished product into the third limiting plate 26 for automatic unloading. Next, the Y-axis drive assembly 22 moves upwards, and the X-axis drive assembly 23 drives... The FPC suction cup 20 moves above the conveyor belt 11, and the Y-axis drive assembly 22 drives the FPC suction cup 20 to move downward. The FPC suction cup 20 places the original FPC product onto the conveyor belt 11. At the same time, the finished product suction cup 4 picks up a new FPC product. The Y-axis drive assembly 22 moves upward, and then the rotating assembly 17 drives the reinforcing plate suction cup 19 to rotate above the conveyor belt 11. The Y-axis drive assembly 22 moves downward, and the reinforcing plate suction cup 19 moves onto the conveyor belt 11. The reinforcing plate suction cup 19 places the reinforcing plate onto the original FPC product, which can be automatically fed. The FPC dummy bonding machine is convenient for loading and unloading. The intelligent loading and unloading structure, combined with the film application device, enables the FPC dummy bonding machine to perform continuous operation, further improving the overall work efficiency.

[0103] like Figure 4 , 6 As shown in Figure 8, the housing 1 is also connected to a tensioning structure for tensioning the transmission component. The tensioning mechanism includes:

[0104] Support member, which is installed at the bottom inside housing 1;

[0105] The support is preferably an n-shaped plate base 33, which is installed at the bottom of the housing 1;

[0106] A reset component is mounted on a support component.

[0107] Tensioning roller 28 is movably mounted on the reset component. The top of tensioning roller 28 contacts the bottom of the transmission component, pushing the transmission component upward to tension it.

[0108] The reset component includes a fixed plate 29, a slide bar 30, a spring 31, and a U-shaped connecting plate 32. Springs 31 are uniformly fixedly connected to the top of the n-shaped plate base 33, and the fixed plate 29 is fixedly connected to the bottom of the springs 31. The U-shaped connecting plate 32 is fixedly connected to the top of the fixed plate 29. The U-shaped connecting plate 32 is rotatably connected to the tension roller 28 through a fixedly connected bearing. The top of the tension roller 28 contacts the bottom of the conveyor belt 11. The restoring force of the spring 31 pushes the U-shaped connecting plate 32 to move upward. The U-shaped connecting plate 32 pushes the tension roller 28 to move upward. The tension roller 28 pushes the conveyor belt 11 upward to tension it.

[0109] The tensioning structure tensions the intermittent drive assembly, ensuring its driving stability and facilitating the accurate movement of the FPC original and reinforcing plate above the active film assembly.

[0110] Mounting bracket 3 is fixedly installed inside the bottom of housing 1.

[0111] A glass door 2 is symmetrically and fixedly connected to the front end of the housing 1 via hinges.

[0112] In use, the top of the tension roller 28 of the tensioning structure contacts the bottom of the conveyor belt 11. The restoring force of the spring 31 pushes the U-shaped connecting plate 32 to move upward. The U-shaped connecting plate 32 pushes the tension roller 28 to move upward, and the tension roller 28 pushes the conveyor belt 11 upward to tension it. This tensioning process on the intermittent drive assembly ensures the driving stability of the intermittent drive assembly and facilitates the accurate movement of the FPC original and the reinforcing plate above the active film application assembly.
