Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board production equipment, and in particular to an adjustable flexible circuit board laminating machine. Background Technology

[0002] As an important piece of equipment in the electronics manufacturing industry, laminating machines uniformly press protective films onto the surface of flexible circuit boards during the production process. This protects the circuits from damage caused by the external environment, such as moisture, dust, and mechanical stress, thereby improving the reliability and service life of the product. In the traditional flexible circuit board lamination process, film cutting relies on manual operation, which is not only inefficient but also prone to inconsistent cutting precision due to human factors, affecting the consistency of the final product quality. Now, some highly automated laminating machines have emerged.

[0003] A flexible circuit board production laminating machine with announcement number CN221768371U integrates lamination and cutting operations, significantly improving production efficiency and ensuring consistent cutting precision. However, the fixed cutting position causes the cut film to easily drift away in the wind, making subsequent collection and sorting inconvenient.

[0004] If the cutting position is set too low, the cut film is directly exposed to the operating environment. Prolonged exposure not only easily attracts dust, affecting the cleanliness of the film, but also lacks tension support, making it difficult to neatly wind and recycle the film, increasing the risk of material waste. Conversely, if the cutting position is too high, although the above problems can be avoided, the film, having lost its tension after cutting, may not adhere tightly during the lamination process, affecting the lamination effect and thus impacting the overall performance of the flexible circuit board. Utility Model Content

[0005] To overcome the limitation of the cutting position, this utility model provides a flexible circuit board laminating machine with an adjustable cutting position.

[0006] An adjustable flexible circuit board laminating machine includes a laminating machine with support frames connected to the upper left and right sides. An electric slide rail is mounted on one side of each support frame, and a slide groove is provided on the other side. A connecting plate is slidably connected within the electric slide rail, and a guide plate is slidably connected within the slide groove. Two connecting plates and two guide plates are connected together to a blade holder. A motor and a first mounting bracket are mounted on the blade holder. A moving plate is connected between the two first mounting brackets, and a cutting component is slidably connected to the moving plate. A transmission component is provided between the first mounting bracket and the output shaft of the motor. A controller is mounted on the laminating machine and is wiredly connected to the motor and the electric slide rail. A clamping assembly for fixing the film is provided on the blade holder.

[0007] More preferably, the clamping assembly includes a second mounting bracket, which is connected to the left and right ends of the tool holder. An electric push rod is mounted on the second mounting bracket, and a pressing block is connected to the piston rod of the electric push rod. The pressing block is in pressing engagement with the second mounting bracket.

[0008] More preferably, a rubber pad is connected to the side of the extrusion block that contacts the second mounting bracket.

[0009] More preferably, a top plate is connected to the second mounting bracket.

[0010] More preferably, protective plates are connected to the left and right sides of the support frame.

[0011] More preferably, the support frame is equipped with a scale.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Through the cooperation of electric slide rail, connecting plate, and guide plate, the electric slide rail can drive the knife holder to different positions as needed. Whether it is to make precise cuts close to the flexible circuit board or to move to the bottom of the feeding roller to facilitate the coating of the last circuit board, it can be easily achieved, thus achieving the purpose of flexibly adapting to different operation needs.

[0014] 2. By using a clamping assembly, a portion of the film is held in place before cutting, ensuring that the upper part of the film remains taut after cutting until the next circuit board to be coated passes through. This facilitates subsequent operations by the staff and improves the smoothness and efficiency of the entire coating process. Attached Figure Description

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example: An adjustable flexible circuit board laminating machine, such as Figures 1-3 As shown, the assembly includes a film pressing machine 1, a support frame 2, a knife holder 21, a motor 22, a transmission component 23, a first mounting frame 24, a moving plate 25, a cutting component 26, a controller 3, an electric slide rail 4, a connecting plate 5, a guide plate 6, and a clamping assembly. The film pressing machine 1 is equipped with a conveyor belt for moving the flexible circuit board, a feeding roller for placing the film roll, and a coating roller for pressing the film. The upper left and right sides of the film pressing machine 1 are connected to the support frame 2. An electric slide rail 4 is installed on one side of the two support frames 2, and a groove is provided on the other side. A connecting plate 5 is slidably connected in the electric slide rail 4, and a guide plate 6 is slidably connected in the groove. The two connecting plates 5 and the two guide plates 6 are connected together to the knife holder 21. The blade holder 21 is slidably connected to the support frame 2. A motor 22 and two first mounting brackets 24 are installed on the blade holder 21. A moving plate 25 is connected between the first mounting brackets 24. A cutting piece 26 is slidably connected on the moving plate 25, and the moving plate 25 can directly drive the cutting piece 26 to move left and right. The left and right sides of the cutting piece 26 are sharp. A transmission component 23 is provided between the first mounting bracket 24 and the output shaft of the motor 22. The transmission component 23 is a gear and rack. A controller 3 is installed on the film pressing machine 1. The controller 3 is wired to the motor 22 and the electric slide rail 4, and controls the start and stop of the moving plate 25, that is, controls the left and right movement of the cutting piece 26. A clamping assembly for fixing the film is provided on the blade holder 21.

[0021] like Figure 3 As shown, the clamping assembly includes a second mounting bracket 7, an electric push rod 8, and a pressing block 9. The second mounting bracket 7 is connected to the left and right ends of the tool holder 21. The electric push rod 8 is mounted on the second mounting bracket 7. The pressing block 9 is connected to the piston rod of the electric push rod 8. The pressing block 9 is pressed and engaged with the second mounting bracket 7.

[0022] The flexible circuit board passes over the conveyor belt of the laminating machine 1. After the film is pulled out from the upper feeding roller, it passes through the bottom coating roller to complete the lamination of the flexible circuit board. After one circuit board is laminated, the film is cut and the position of the film is maintained by the clamping component. When cutting the film, the operator starts the motor 22 through the controller 3. The motor 22 drives the moving plate 25 through the transmission component 23, so that the moving plate 25 is close to the film. The cutting component 26 moves with the moving plate 25 and contacts the film. Then the moving plate 25 drives the cutting component 26 to cut the film. The remaining film is lowered by the cutting component 26 and is squeezed by the coating roller to complete the lamination. The film above the cutting component 26 is clamped by the clamping component to maintain the film in a stretched state. When the unlaminated flexible circuit board passes through the laminating machine 1, the clamping component releases the film. The operator passes one end of the film around the coating roller to perform the lamination work. After the cutting is completed, the motor 22 reverses and resets the moving plate 25 and the cutting component 26 through the transmission component 23.

[0023] Before cutting with the cutting piece 26, the operator starts the electric push rod 8 through the controller 3. The electric push rod 8 drives one extrusion block 9 to move towards another extrusion block 9 while clamping the film. In this way, after cutting, the upper part of the film can still remain taut. When lamination is required, the electric push rod 8 pulls the extrusion block 9 to release the film. Moreover, during continuous operation, the electric slide rail 4 drives the knife holder 21 to the bottom through the connecting plate 5, thereby getting close to the flexible circuit board. After cutting, the film is close to the lamination roller, and the distance the operator pulls the film is very short, and the pulled film can maintain tension. When laminating the last flexible circuit board, the electric slide rail 4 drives the knife holder 21 to move to the bottom of the feeding roller. When cutting, the operator pinches both ends of the film, thereby ensuring the tension of the film during lamination and completing the lamination work of the last flexible circuit board.

[0024] like Figure 3 As shown, it also includes a rubber pad 10, and the side of the extrusion block 9 that contacts the second mounting bracket 7 is connected to the rubber pad 10.

[0025] When the two extrusion blocks 9 clamp the membrane, the rubber pad 10 can reduce membrane damage, thereby protecting the membrane's performance.

[0026] like Figure 3 As shown, it also includes a top plate 11, which is connected to the second mounting bracket 7. When the electric push rod 8 is fully retracted, the top plate 11 is closer to the second mounting bracket 7 than the extrusion block 9.

[0027] When the extrusion plate on the electric push rod 8 detaches from the second mounting bracket 7, the membrane comes into contact with the top plate 11, thereby separating the membrane from the extrusion block 9. After the extrusion block 9 is reset, the membrane will no longer stick to the adhesive pad 10.

[0028] like Figure 1As shown, it also includes a protective plate 12. The support frame 2 is connected to the left and right sides with protective plates 12. The protective plates 12 cover the electric slide rail 4 and the connecting plate 5, and the protective plates 12 protect the electric slide rail 4.

[0029] like Figure 1 As shown, it also includes a scale 13, and the support frame 2 is equipped with a scale 13.

[0030] During the adjustment of the tool holder 21, the ruler 13 allows for a direct understanding of the distance moved each time and records the position after each adjustment. The ruler 13 helps staff to intuitively understand and record the distance moved by the tool holder 21 each time, providing a reference for subsequent precise adjustments.

[0031] During operation, the flexible circuit board (PCB) passes through the conveyor belt of the laminating machine 1, while the film is drawn from the upper feed roller and applied to the PCB surface by the coating roller. Once one PCB is coated, the motor 22 starts, driving the cutting element 26 on the moving plate 25 to approach and cut the film via the transmission component 23. During this process, the clamping assembly on the blade holder 21 pre-clamps a portion of the film, ensuring the upper half of the cut film remains taut. The lower half of the cut film continues to coat the next PCB under the action of the coating roller, while the upper half is held at tension by the clamping assembly until the next PCB to be coated passes through the laminating machine 1. At this point, the clamping assembly releases, and the operator rewinds the film around the coating roller for the next coating cycle. Furthermore, the electric slide rail 4 can adjust the position of the blade holder 21 as needed to optimize the distance between the cut film and the coating roller, facilitating operator operation and maintaining film tension. During continuous operation, the electric slide rail 4 can also drive the blade holder 21 to the bottom of the feed roller, facilitating the completion of the coating of the last PCB. The protective plate 12 protects the electric slide rail 4 from external interference, while the scale 13 provides an intuitive reference for adjustment distance, ensuring accurate adjustment each time. Throughout the entire process, the rubber pad 10 reduces film damage, and the top plate 11 helps the film to smoothly separate from the extrusion block 9 when the electric push rod 8 resets, preventing film adhesion and ensuring the efficient and stable operation of the film press 1.

[0032] 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 present invention and should not be construed as limiting the scope of protection of the present invention in any way.
