Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board processing technology, and in particular to a rolling mechanism for flexible circuit board processing equipment. Background Technology

[0002] In the production process of flexible printed circuit boards, copper foil needs to undergo etching and other processes to obtain the required circuit, and protective film needs to be drilled to expose the corresponding pads. After cleaning, the two are then combined using a rolling method, which requires the use of rolling equipment.

[0003] In order to understand the existing rolling equipment, a search was conducted and a rolling device for circuit board production and processing with publication number CN220493219U was found. In this patent, the flexible circuit board is fixed by a negative pressure suction nozzle. The flexible circuit board is processed and then removed one by one before the next step of rolling the flexible circuit board can be carried out. This will reduce the rolling efficiency of the flexible circuit board.

[0004] Secondly, Chinese patent CN206341480U discloses a rolling mechanism for flexible circuit board processing equipment. Although it can drive the pressure roller frame to rise or fall, thereby adjusting the vertical position of the pressure roller and thus adjusting the rolling pressure of the pressure roller on the flexible circuit board, it cannot detect the specific value of the rolling pressure of the pressure roller on the flexible circuit board. This is because different specifications and models of flexible circuit boards require different pressures, and the pressure value is the method of judgment.

[0005] Therefore, this application proposes a rolling mechanism for flexible circuit board processing equipment. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a rolling mechanism for flexible circuit board processing equipment.

[0007] An embodiment of this utility model provides a rolling mechanism for flexible circuit board processing equipment, comprising:

[0008] The support platform is provided with two sets of vacuum holes;

[0009] A rolling assembly includes a movable frame that moves above a support platform. The movable frame has two guide blocks that slide vertically. A detachable connecting frame is mounted on the bottom of each mounting block. Pressure rollers are rotatably mounted on the two connecting frames. A pressure sensor and a guide rod are mounted on the upper end of each mounting block. A spring is fitted onto the guide rod, abutting against the pressure sensor. A sliding, vertically movable rod is fitted onto the guide rod, with the spring abutting against the lower end of the movable rod. The pressure rollers move above two sets of vacuum holes, rolling the flexible circuit board adsorbed by the vacuum holes one by one. The two sets of vacuum holes are used alternately.

[0010] Furthermore, two sets of vacuum generators are installed at the bottom of the support platform, and the two sets of vacuum generators are respectively connected to two sets of vacuum holes.

[0011] Furthermore, electric slide rails are fixed on both sides of the support platform, and electric sliders slide on the electric slide rails. The movable frame is mounted on the electric sliders.

[0012] Furthermore, an electric push rod is installed on the movable frame, and a drive rod is fixed to the output end of the electric push rod. The drive rod is fixedly connected to the upper end of the movable rod.

[0013] Furthermore, the upper end of the guide rod is provided with a threaded groove, and a bolt is threaded into the threaded groove. The bolt is located above the moving rod and limits its movement, so that the moving rod will not detach from the guide rod.

[0014] Furthermore, the connecting bracket is fixed to the bottom of the mounting block by multiple screws.

[0015] Furthermore, the inner wall of the movable frame is provided with a guide rail, and the connecting frame is provided with a guide groove for use with the guide rail, and the guide rail is located in the guide groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The moving rod slides downwards on the guide rod, compressing the spring. Since the spring is against the pressure sensor, the spring is compressed and transmits pressure to the pressure sensor. The pressure sensor detects the rolling pressure of the pressure roller on the flexible circuit board in real time to ensure that the rolling pressure meets the requirements of this type of circuit board.

[0018] 2. By controlling the compression of the spring, the rolling pressure of the pressure roller can be controlled, adapting to different models and subsequent circuit board rolling.

[0019] 3. Two sets of vacuum holes are used alternately to achieve continuous operation, greatly improving rolling efficiency. During the rolling process, precise control of the rolling pressure is maintained at all times to ensure that each flexible circuit board receives high-quality rolling treatment.

[0020] 4. Turn the bolt to remove it, which will allow you to remove the moving rod and take out the spring for replacement.

[0021] This utility model features a pressure sensor that monitors the rolling pressure of the pressure roller on the flexible circuit board in real time, ensuring that the rolling pressure meets the requirements of the circuit board model. Two sets of vacuum holes are used alternately to achieve continuous operation, which greatly improves the rolling efficiency. During the rolling process, the rolling pressure is always precisely controlled to ensure that each flexible circuit board receives high-quality rolling treatment. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a rolling mechanism for flexible circuit board processing equipment, comprising:

[0028] A support platform 1 is provided, with two sets of vacuum holes 4 evenly distributed on the platform. The layout of each set of vacuum holes 4 is optimized according to the common size and shape of flexible circuit boards to ensure the stability and uniformity of the adsorption of the flexible circuit boards. Two sets of vacuum generators 3 are installed at the bottom of the support platform 1, and each set of vacuum generators 3 is connected to one of the two sets of vacuum holes 4. The vacuum generators 3 are high-efficiency and energy-saving, and have an automatic start-stop function. They automatically start when a flexible circuit board is detected placed above the vacuum hole 4, and automatically shut down when no flexible circuit board is detected, in order to reduce energy consumption.

[0029] The rolling assembly includes a movable frame 5 that moves above the support platform 1. Electric slide rails 2 are fixed to both sides of the support platform 1. The electric slide rails 2 are high-precision, high-rigidity linear guides to ensure the smooth and accurate movement of the movable frame 5. An electric slider slides on the electric slide rail 2, and the movable frame 5 is mounted on the electric slider. The electric slider has a self-locking function, reliably locking itself after the movable frame 5 reaches the designated position to prevent deviation during the rolling process.

[0030] The movable frame 5 has two guide blocks 10 that slide up and down. The inner wall of the movable frame 5 has a guide rail 12, the surface of which is hardened to improve wear resistance and service life. The connecting frame 11 has a guide groove 14 that cooperates with the guide rail 12. The guide rail 12 is located within the guide groove 14, and the guide groove 14 and the guide rail 12 are clearance-fitted, ensuring smooth sliding of the mounting blocks 10 while preventing wobbling. A detachable connecting frame 11 is installed at the bottom of the mounting blocks 10. The connecting frame 11 is fixed to the bottom of the mounting blocks 10 by multiple screws 18 made of high-strength alloy steel to ensure a firm connection and facilitate the disassembly and replacement of the pressure roller 9.

[0031] Two connecting brackets 11 are rotatably mounted with pressure rollers 9. The pressure rollers 9 are made of highly elastic and wear-resistant rubber material, and their surfaces are specially treated to improve the friction with the flexible circuit board without damaging it. A pressure sensor 17 and a guide rod 16 are mounted on the upper end of the mounting block 10. The pressure sensor 17 has high precision and high sensitivity, and can accurately detect the rolling pressure of the pressure rollers 9 on the flexible circuit board in real time, transmitting the data to the control system. A spring 13 is fitted onto the guide rod 16 to abut against the pressure sensor 17. The spring 13 is made of high-quality spring steel and has undergone heat treatment, giving it good elasticity and stability.

[0032] A sliding movable rod 8, capable of moving up and down, is fitted onto the guide rod 16. An electric push rod 6 is mounted on the movable frame 5. The electric push rod 6 is a servo electric push rod, characterized by high precision and high response speed, capable of accurately controlling the lifting height and rolling pressure of the pressure roller 9. A drive rod 7 is fixed to the output end of the electric push rod 6. The drive rod 7 is fixedly connected to the upper end of the movable rod 8. The upper end of the guide rod 16 is provided with a threaded groove, and a bolt 15 is threaded into the groove. The bolt 15 is located above the movable rod 8 and limits its movement, preventing the movable rod 8 from detaching from the guide rod 16. When the movable rod 8 moves upward and abuts against the bolt 15, it can drive the pressure roller 9 to move upward.

[0033] Spring 13 abuts against the lower end of the moving rod 8; the pressure roller 9 moves above the two sets of vacuum holes 4 respectively, rolling the flexible circuit boards adsorbed by the vacuum holes 4 one by one. The two sets of vacuum holes 4 are used alternately. During the rolling process, the control system adjusts the output force of the electric push rod 6 in real time according to the data fed back by the pressure sensor 17, ensuring that the rolling pressure of the pressure roller 9 on the flexible circuit board is always kept within a suitable range. At the same time, when the flexible circuit board on one set of vacuum holes 4 has been rolled, the moving frame 5 automatically moves to the other set of vacuum holes 4 for rolling, realizing continuous operation and greatly improving the rolling efficiency.

[0034] Step 1, Flexible Circuit Board Placement and Adhesion: The operator places the flexible circuit board on the support platform 1 above one of the sets of vacuum holes 4. The vacuum generator 3 at the bottom of the support platform 1 automatically starts after detecting the placement of the flexible circuit board, generating negative pressure through the vacuum holes 4 to firmly adhere the flexible circuit board to the support platform 1, ensuring that the flexible circuit board will not move during the subsequent rolling process.

[0035] Step 2, the rolling assembly moves to the rolling position: the control system controls the electric slider on the electric slide rail 2 to move according to the preset program, driving the moving frame 5 to move smoothly and accurately along the electric slide rail 2 to the vacuum hole 4 on which the flexible circuit board is placed.

[0036] Step 3, Roller Descending and Rolling: The control system activates the electric push rod 6, whose output drives the drive rod 7 downwards. The drive rod 7 is fixedly connected to the upper end of the moving rod 8. The moving rod 8 slides downwards on the guide rod 16, compressing the spring 13. Since the spring 13 abuts against the pressure sensor 17, the compressed spring 13 transmits pressure to the pressure sensor 17. The pressure sensor 17 detects the rolling pressure of the roller 9 on the flexible circuit board in real time and transmits the data to the control system. As the moving rod 8 slides downwards, it drives the mounting block 10 to move downwards along the guide rail 12, thereby causing the connecting frame 11 and the roller 9 to descend, bringing the roller 9 into contact with the flexible circuit board.

[0037] As the electric push rod 6 continues to output power, the pressure roller 9 applies rolling pressure to the flexible circuit board and performs a rolling operation on the surface of the flexible circuit board. During the rolling process, the control system adjusts the output force of the electric push rod 6 in real time based on the data fed back by the pressure sensor 17, ensuring that the rolling pressure of the pressure roller 9 on the flexible circuit board is always kept within a preset appropriate range.

[0038] Step 4: Complete the rolling of a set of flexible circuit boards: After the pressure roller 9 completes the rolling of the flexible circuit board above the vacuum hole 4, the control system controls the electric push rod 6 to move in the opposite direction, driving the drive rod 7, the moving rod 8, the mounting block 10, the connecting frame 11 and the pressure roller 9 to rise, so that the pressure roller 9 is separated from the flexible circuit board.

[0039] Vacuum generator 3 stops working, releasing the suction on the flexible circuit board, and the operator removes the rolled flexible circuit board.

[0040] Step 5, alternating rolling: The movable frame 5 moves on the electric slide rail 2 to above another set of vacuum holes 4, and repeats steps 2 to 4 above to perform rolling operation on the flexible circuit board placed above the set of vacuum holes 4.

[0041] Two sets of vacuum holes are used alternately to achieve continuous operation, greatly improving the rolling efficiency. During the rolling process, precise control of the rolling pressure is maintained at all times to ensure that each flexible circuit board receives high-quality rolling treatment.

[0042] The control system described above uses PLC technology, which will not be elaborated on further here as it is existing technology.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
