Description

Technical Field

[0001] This utility model relates to the flexible circuit board roll production industry, and in particular to a flexible circuit board alignment system. Background Technology

[0002] Flexible printed circuit boards (FPCBs) are prone to lateral shift during high-speed roll-to-roll production, leading to decreased precision in processes such as lamination and etching. Traditional web-correcting devices often use mechanical limiters or photoelectric sensors to detect edge positions and correct the shift by laterally moving rollers. One method uses two pairs of photoelectric sensors symmetrically distributed on both sides of the flexible circuit board, triggering a stepper motor to adjust the roller position by detecting edge occlusion signals. However, this traditional method suffers from the risk of damage to the flexible circuit board due to the mechanical lateral movement of the rollers. Furthermore, the photoelectric sensors are fixed and can only detect shift signals during roll-to-roll production within their fixed detection range. When the width of the flexible circuit board changes, or when the instantaneous shift exceeds the detection range of the photoelectric sensors, the sensor positions cannot be adjusted in time, resulting in the loss of the web-correcting signal. Utility Model Content

[0003] To overcome the above problems, this utility model provides a flexible circuit board alignment system. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0004] A flexible circuit board alignment system includes an alignment mechanism and a sensor mechanism electrically connected to a central controller. The alignment mechanism includes a deflection assembly with a roller assembly mounted on it. The sensor mechanism includes a parallel motorized guide rail assembly and a reflector, with a reflective light sensor mounted on the motorized guide rail assembly. The flexible circuit board passes through the reflector and the motorized guide rail assembly without contact, and then through the roller assembly. The motorized guide rail assembly drives the reflective light sensor to move left and right along the motorized guide rail assembly to track the edge of the flexible circuit board. The deflection assembly drives the roller assembly to shift left / right by an angle to adjust the position of the flexible circuit board.

[0005] Furthermore, the electric guide rail assembly includes a guide rail bracket, an encoder motor is mounted on the guide rail bracket, a drive wheel is mounted on the movable end of the encoder motor, a driven wheel is mounted on the guide rail bracket, the drive wheel and the driven wheel are connected by a transmission belt, a sensor mounting base is mounted on the transmission belt, and a reflective light sensor is mounted on the sensor mounting base.

[0020] 300. Flexible circuit board. Detailed Implementation

[0021] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the "Flexible Circuit Board Correction System" is provided in conjunction with the accompanying drawings.

[0022] See Figure 1 and Figure 2 In this embodiment, the flexible circuit board correction system includes a correction mechanism 100 and a sensor mechanism 200 electrically connected to a central controller. The correction mechanism 100 includes a deflection assembly 101, on which a roller assembly 102 is disposed. The sensor mechanism 200 includes a parallel electric guide rail assembly 201 and a reflector 202, on which a reflective light sensor 203 is disposed. During operation, the flexible circuit board 300 is pulled through the reflector 202 and the electric guide rail assembly 201 without contact, and then turns after passing through the roller assembly 102. The flexible circuit board 300 rolls on the roller assembly 102, causing the roller assembly 102 to roll. When the edge of the flexible circuit board 300 on the roller assembly 102 exceeds the correction sensing range of the reflective light sensor 203, and the correction mechanism 100 cannot correct the flexible circuit board back to the initial setting position of the sensor correction point in time, the system will continue to operate. When the motor guide rail assembly 201 is in place, it drives the reflective light sensor 203 to move left and right along the motor guide rail assembly 201 to track the edge of the flexible circuit board 300, so that the edge of the flexible circuit board 300 is always kept within the correction sensing range of the reflective light sensor 203. The central controller determines a new correction position set point (new process requirement position) based on the moving distance fed back by the motor guide rail assembly 201 and the signal from the reflective light sensor 203, thereby maintaining the continuity of the correction signal. After receiving the correction signal, the central controller controls the deflection assembly 101 to operate. The deflection assembly 101 drives the roller assembly 102 to deflect to the left / right by an angle. As the roller assembly 102 deflects to the left / right by an angle, the flexible circuit board 300 will gradually move to the left / right as it continues to roll, gradually adjusting the position of the flexible circuit board 300 to the required process position, thus completing the correction of the flexible circuit board 300.

[0023] It should be noted that the sensor mechanism 200 of this system can dynamically adjust the position of the reflective light sensor 203 to track the edge of the circuit board and maintain the stability of the correction signal; and the correction mechanism 100 of this system achieves flexible adjustment of the position of the circuit board by fine-tuning the angle of the roller assembly 102, without damaging the substrate of the flexible circuit board 300.

[0024] See further Figure 1 In this embodiment, the electric guide rail assembly 201 includes a guide rail bracket 2011, on which an encoder motor 2012 is mounted. The encoder motor 2012 has a position encoder that can provide feedback on the distance driven by the motor. The movable end of the encoder motor 2012 is provided with a drive wheel (not shown), and the guide rail bracket 2011 is provided with a driven wheel (not shown). The drive wheel and the driven wheel are connected by a transmission belt. A sensor mounting base 2013 is provided on the transmission belt, and a reflected light sensor 203 is mounted on the sensor mounting base 2013. The encoder motor 2012 can achieve a response speed of less than 50 milliseconds, which greatly improves the correction sensitivity.

[0025] In other embodiments, the electric guide rail assembly 201 includes a guide rail bracket 2011, on which an encoder motor 2012 and a drive guide rail module (not shown) are mounted. The drive guide rail module is equipped with a sensor mounting base 2013, and a reflected light sensor 203 is mounted on the sensor mounting base 2013. The encoder motor 2012 drives the reflected light sensor 203 to move along the electric guide rail assembly 201 through the drive guide rail module. The drive guide rail module has a faster response rate than belt pulley transmission, which can further improve the sensitivity of correction.

[0026] See further Figure 3 and Figure 4 In this embodiment, the deflection assembly 101 includes a base 1011, on which a deflection cylinder 1012 and an inclined slide rail 1013 are mounted. The inclined slide rail 1013 is set at an angle to the axis of the roller assembly 102. The roller assembly 102 is slidably mounted on the inclined slide rail 1013. The movable end of the deflection cylinder 1012 is connected to the roller assembly 102, and the deflection cylinder 1012 drives the roller assembly 102 to slide along the inclined slide rail 1013 to adjust the angle of the roller assembly 102. Preferably, the inclined slide rail 1013 is a load-bearing bearing, and the bottom of the roller assembly 102 is sleeved on the load-bearing bearing and can slide along the load-bearing bearing. This ensures that the sliding of the roller assembly 102 is more stable, and the deflection assembly 101 can meet the requirements of correction operations with greater weight.

[0027] More specifically, in this embodiment, the roller assembly 102 includes a roller frame 1021, on which two parallel rubber-coated rollers 1022 are disposed. The flexible circuit board 300 rolls on the rubber-coated rollers 1022, driving the rubber-coated rollers 1022 to roll. The two parallel rubber-coated rollers 1022 provide the ability to withstand greater correction weight, resulting in more stable correction. Furthermore, the rubber-coated rollers 1022 are coated with nitrile rubber, which will not damage the flexible circuit board 300 and can provide greater friction, improving correction sensitivity.
