Description

Technical Field

[0001] This application relates to the field of circuit board manufacturing technology, and in particular to a flexible circuit board multi-head rotary switching device. Background Technology

[0002] With the rapid development of flexible printed circuit board (FPCB) electronic products, the quality requirements for FPCBs are becoming increasingly stringent, and the demand is growing significantly. In the production process of FPCBs, the reinforcing machine plays a crucial role in precisely bonding reinforcing materials to designated areas on the circuit board to enhance its mechanical strength and stability. Currently, the widely used single-axis stamping reinforcing machine faces significant technical bottlenecks. In actual production, when different types of bonding heads need to be replaced to adapt to the reinforcement requirements of different FPCB models, operators must disassemble the equipment. After installation, a series of complex debugging tasks are required, including calibration of parameters such as bonding head position, pressure, and bonding accuracy. This process not only consumes a significant amount of time and manpower but also severely impacts production efficiency and extends product delivery cycles. More importantly, during bonding head replacement, even slight errors in installation can easily lead to defects in the reinforced product. For example, a misalignment of the bonding head may result in inaccurate bonding of the reinforcing material, and improper pressure adjustment may cause the reinforcing material to not bond firmly to the flexible circuit board, thereby affecting the overall performance and quality of the flexible circuit board, increasing the product defect rate, and raising the company's production costs.

[0049] like Figure 1 As shown, Figure 1This is a schematic diagram of the structure of the flexible circuit board multi-head rotary switching device provided in the embodiment of this application. The flexible circuit board multi-head rotary switching device includes a first servo motor 100, a servo motor support frame 300, a second servo motor 200, a ball screw module 400, a converter module 500, multiple bonding heads 600, a fixed base 700, and a controller (not shown in the figure).

[0050] Specifically, the first servo motor 100 is fixedly connected to one side of the servo motor support frame 300, the second servo motor 200 is fixedly connected to the other side of the servo motor support frame 300, the ball screw module 400 is connected to the second servo motor 200, the converter module 500 is connected to the ball screw module 400, multiple bonding heads 600 are disposed on the converter module 500, one end of the fixed base 700 is connected to the converter module 500, and the other end is fixedly connected to the wall or support frame. The controller is communicatively connected to the first servo motor 100, the second servo motor 200, and the converter module 500. The flexible circuit board multi-bonding head rotation switching device uses the controller to control the first servo motor 100 to drive the servo motor support frame 300 to move up and down to ensure a safe working distance between the flexible circuit board multi-bonding head rotation switching device and the flexible circuit board. By raising the overall height of the equipment to accommodate reinforcing materials of different thicknesses, the bonding heads 600 that adsorb reinforcing materials will not touch the flexible circuit board during the movement of the flexible circuit board with the conveyor belt. The controller controls the second servo motor 200, which drives the ball screw module 400. The ball screw module 400 applies pressure to the bonding head 600 during operation for reinforcement. It also works with the converter module 500 to switch bonding heads 600, ensuring a tight connection between the bonding head 600 and the ball screw module 400. When the controller determines to switch bonding heads 600, it controls the converter module 500 to rotate multiple bonding heads 600 until the ball screw module 400 is directly aligned with the selected bonding head 600. Through the coordination of the ball screw module 400 controlled by the second servo motor 200 and the converter module 500, the ball screw module 400 and the bonding head 600 are precisely and tightly connected, completing the bonding head 600 switching. This flexible circuit board multi-bonding head rotation switching device allows for direct replacement of the required bonding head 600 during operation, eliminating the need for repeated machine shutdowns for installation. This significantly improves production efficiency and stability, avoids errors and time-consuming manual installation, and reduces equipment debugging time.

[0051] In some embodiments, the ball screw module 400 includes a ball screw, a coupling, a screw support assembly, and a nut seat. The second servo motor 200 is connected to the ball screw via the coupling. The screw support assembly is fitted onto the ball screw. The ball screw is connected to the converter module 500 via the nut seat. The screw support assembly includes a radial thrust bearing and a bearing fixing support. The radial thrust bearing is fitted onto the ball screw with an interference fit. One end of the bearing fixing support is fixedly connected to the radial thrust bearing, and the other end of the bearing fixing support is fixedly connected to a wall.

[0052] Specifically, the components of the ball screw module 400 are precisely connected to achieve power transmission and precise motion control. The second servo motor 200, as the power source, is rigidly connected to the ball screw via a coupling, transmitting its rotational motion to the ball screw. The coupling compensates for coaxiality errors between the two shafts and transmits torque; additionally, some flexible couplings absorb minor vibrations, protecting the second servo motor 200 and the ball screw from rigid impacts. The screw support assembly is mounted on the ball screw, and its internal radial thrust bearing is tightly fitted onto the ball screw via an interference fit, providing support. The radial thrust bearing can simultaneously withstand the radial and axial loads generated during screw rotation, limiting axial movement and ensuring the stability and coaxiality of the screw rotation. One end of the bearing fixing support is fixedly connected to the radial thrust bearing, and the other end is fixedly connected to a wall or frame, providing a stable support foundation for the entire flexible circuit board multi-head rotary switching device, ensuring the ball screw maintains positional accuracy during rotation. The ball screw and converter module 500 are connected via a nut seat, which fits tightly with the nut on the ball screw. When the ball screw rotates under the drive of the second servo motor 200, the nut seat moves linearly along the screw axis, thereby driving the bonding head 600 on the converter module 500 to move up and down, realizing the downward pressing or upward resetting action of the bonding head 600. As the actuator of the linear motion of the screw, the nut seat accurately converts the rotational motion of the screw into linear displacement, ensuring the motion accuracy of the converter module 500, thus meeting the high-precision requirements of the FPC reinforcement process for the positioning and pressure control of the bonding head 600.

[0053] In some embodiments, such as Figure 2 As shown, Figure 2This is a schematic diagram of the structure of multiple bonding heads on the turntable. The converter module 500 in the flexible circuit board multi-bonding head rotary switching device includes a gear drive device, an internal rotating structure, a vacuum nozzle, a rotary frame, and a quick connector. The gear drive device, internal rotating structure, vacuum nozzle, and quick connector are located inside the rotary frame. The gear drive device includes a third servo motor and a driven gear set; the third servo motor drives the driven gear set to rotate; the third servo motor is communicatively connected to the controller. The internal rotating structure includes a rotating shaft, a turntable 510, and a bearing assembly; the rotating shaft is fixedly connected to the turntable 510; the bearing assembly is connected to the rotating shaft; multiple bonding heads 600 are disposed on the turntable 510.

[0054] Specifically, in the converter module 500 of the flexible circuit board multi-head rotary switching device, the components work closely together to achieve automatic switching and precise positioning of the mounting heads 600. The rotary frame serves as the basic framework, providing mounting support for the gear drive device, the internal rotating structure, the vacuum nozzle, and the quick connector, ensuring the stability of the relative positions of each component. The gear drive device consists of a third servo motor and a driven gear set. The third servo motor communicates with the controller, receiving control commands and outputting power. The motor meshes with the driven gear set via a shaft, driving the driven gear set to rotate. During this process, gear transmission achieves speed reduction and torque increase, converting the high speed of the motor into a low speed suitable for the rotation of the turntable 510, and increasing torque to provide stable and precise rotational power for the internal rotating structure. The core component of the internal rotating structure, the rotating shaft, is fixedly connected to the turntable 510, ensuring that the turntable 510 rotates synchronously with the rotating shaft. The bearing assembly is connected to the rotating shaft. The inner ring of the bearing is interference-fitted with the rotating shaft, while the outer ring is fixed to the rotator frame. This effectively supports the rotating shaft, bearing the radial and axial loads generated during the rotation of the turntable 510, reducing friction and wear on the rotating shaft, and ensuring the smoothness and positioning accuracy of the turntable 510's rotation. Multiple bonding heads 600 are evenly distributed on the turntable 510. When the turntable 510 rotates under the drive of the rotating shaft, different bonding heads 600 can be switched to meet the operational needs of various specifications of reinforcing materials. A vacuum nozzle is integrated inside the bonding head 600 and connected to an external vacuum generator via an air pipe to generate negative pressure to adsorb the reinforcing material. Quick connectors are respectively located on the lead screw module and the bonding head 600. When the turntable 510 rotates the target bonding head 600 to its position, the lead screw module descends, and the male and female heads of the quick connectors automatically engage, realizing power transmission between the lead screw module and the bonding head 600. This allows the lead screw module to push the bonding head 600 to complete the downward reinforcement operation. The turntable 510 can have multiple adhesive heads, and the number of adhesive heads 600 is determined according to the area of ​​the turntable 510 and the position layout of the adhesive heads 600.

[0055] In some embodiments, in the flexible circuit board multi-head rotary switching device, the turntable 510 is set at a 90° angle with multiple heads 600. The converter module 500 also includes a positioning pin and a pressure sensor. The positioning pin includes a cylindrical pin and a positioning hole. The cylindrical pin is set on the turntable 510 or the rotator frame, and the positioning hole is set in the ball screw module 400. The pressure sensor is communicatively connected to the controller.

[0056] Specifically, the turntable 510 and multiple bonding heads 600 are set at a 90° angle, allowing the bonding heads 600 to fall vertically onto the surface of the flexible circuit board during operation. This design ensures uniform force distribution on the bonding heads 600 during pressure application, avoiding uneven pressure distribution caused by tilting, thereby improving the accuracy and quality of flexible circuit board reinforcement. When the turntable 510 lowers the bonding heads 600 to the working position, the axis of the bonding heads 600 is perpendicular to the surface of the flexible circuit board, ensuring that when the lead screw module pushes the bonding heads 600 down, the pressure is precisely applied to the reinforcing material in the vertical direction. The positioning pin consists of a cylindrical pin and a positioning hole, and their connection and function are closely coordinated with the operation of the equipment. The cylindrical pin is set on the turntable 510 or the rotator frame, and the positioning hole is located inside the ball screw module 400. When the turntable 510 rotates to the target bonding head 600 aligned with the working position, the cylindrical pin and the positioning hole are precisely aligned. As the lead screw module descends, the cylindrical pin inserts into the positioning hole, achieving precise positioning of the turntable 510 and the lead screw module. This process effectively prevents the bonding head 600 from shifting or rotating during connection, ensuring the coaxiality of the bonding head 600 and the lead screw module, laying a high-precision foundation for subsequent pressure reinforcement operations. The pressure sensor communicates with the controller to monitor the pressure applied by the bonding head 600 to the flexible circuit board in real time. During the process of the lead screw module pushing the bonding head 600 downwards, the pressure sensor converts the detected pressure data into an electrical signal and transmits it to the controller. The controller analyzes and processes the data fed back by the pressure sensor according to preset pressure parameters. If the pressure value deviates from the set range, the controller will promptly adjust the output of the second servo motor 200 to control the downward pressure of the lead screw module, ensuring that the pressure applied by the bonding head 600 is stable and meets process requirements, thereby guaranteeing the stability and reliability of the flexible circuit board reinforcement operation.

[0057] In some embodiments, the system further includes a laser concave sensor, a sensing card, and a photoelectric sensor. The laser concave sensor is disposed on the converter module 500 and is communicatively connected to the controller. The sensing card is disposed next to a plurality of bonding heads 600, and the photoelectric sensor is disposed next to the flexible circuit board to be reinforced and is communicatively connected to the controller.

[0058] Specifically, a laser concave sensor is mounted on the converter module 500 and establishes a communication connection with the controller via a data cable. Its main function is to monitor the surface morphology of the flexible circuit board in real time. Before the bonding head 600 operates, the laser concave sensor emits a laser beam to scan the surface of the flexible circuit board, detecting its thickness, concave / convex positions, or component protrusions, and transmits the data to the controller. The controller adjusts the pressing stroke and pressure parameters of the bonding head 600 based on this data to avoid poor bonding of the reinforcing material due to unevenness of the flexible circuit board surface, ensuring the accuracy of the reinforcing position. Sensing cards are placed next to multiple bonding heads 600 and work in conjunction with photoelectric sensors mounted on the rotary table frame. When the turntable 510 rotates the bonding head 600, the sensing cards move accordingly. The photoelectric sensors continuously emit and receive light beams. When a sensing card passes through the sensing area of ​​the photoelectric sensor, it blocks the light beam. After detecting the signal change, the photoelectric sensor transmits a trigger signal to the controller. The controller processes signals to accurately determine the position and angle of the bonding head 600, ensuring that the lead screw module and bonding head 600 can accurately align after the target bonding head 600 rotates into position, achieving rapid switching and positioning of the bonding head 600. A photoelectric sensor is positioned next to the flexible circuit board to be reinforced and communicates with the controller. During the process of conveying the flexible circuit board to the working position, the photoelectric sensor monitors the board's positioning in real time. When the flexible circuit board enters the sensor's sensing range and blocks the light beam, the sensor immediately sends a signal back to the controller. Upon receiving the signal, the controller determines that the flexible circuit board is in the correct working position and then controls the converter module 500 to drive the corresponding bonding head 600 to perform the reinforcement operation. This achieves automated triggering and precise control of the flexible circuit board reinforcement process, avoiding bonding errors caused by flexible circuit board misalignment.

[0059] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the flexible circuit board multi-head rotation switching device uses a controller as its core, coordinating with components such as the first servo motor 100, the second servo motor 200, the ball screw module 400, and the converter module 500 to achieve automated reinforcement of flexible circuit boards. The controller, acting as the "brain," is responsible for receiving signals from various sensors, processing data, and sending commands. It establishes communication connections with the first servo motor 100, the second servo motor 200, the third servo motor of the gear drive device located in the converter module 500, the laser concave sensor, the pressure sensor, and the photoelectric sensor, coordinating the operating rhythm and parameter settings of each component.

[0060] The first servo motor 100 is connected to the second servo motor 200 via a servo motor support frame 300. The other side of the first servo motor 100 is connected to a wall or fixed support frame. The controller activates the first servo motor 100, which drives the entire flexible circuit board multi-head rotation switching device to move slightly up and down. This adjusts the distance between the bonding head 600 and the flexible circuit board when the second servo motor 200 is not activated. The first servo motor 100 is used when the extension length of the ball screw is insufficient for reinforcing the flexible circuit board, or when the maximum extension length of the ball screw cannot reach the required length. By controlling the first servo motor 100, the overall height of the device is adjusted to reduce the distance between the bonding head 600 and the flexible circuit board. Furthermore, when the reinforcing material adsorbed by the bonding head 600 is thick, the distance between the bonding head 600 and the flexible circuit board is relatively close when the flexible circuit board moves directly below the bonding head 600. During the movement of the flexible circuit board, it is easy to touch other components on the flexible circuit board. It is necessary to increase the distance between the bonding head 600 and the flexible circuit board. The overall height of the device is adjusted by the first servo motor 100 to protect the flexible circuit board. Both the fixed base 700 and the bearing fixing support are connected to the wall or a fixed support frame. The connection between the fixed base 700 and the converter module 500 mainly serves a supporting function. The connection between the bearing fixing support and the radial thrust bearing is used to prevent shaking and to reduce vibration through transmission. During the process of adjusting the overall height of the first servo motor 100, the fixed base 700 and the bearing fixing support do not restrict the rise or fall of the converter module 500 and the radial thrust bearing, respectively. Furthermore, lubricating oil is provided at the connection points between the fixed base 700 and the converter module 500, as well as between the bearing fixing support and the radial thrust bearing, to reduce the resistance effect during the movement of the converter module 500 and the radial thrust bearing.

[0061] The second servo motor 200 is one of the power sources, connected to the ball screw in the ball screw module 400 via a coupling. When the controller issues a command, the second servo motor 200 starts, transmitting rotational motion to the ball screw via the coupling. The coupling compensates for coaxiality errors, transmits torque, and absorbs vibration, ensuring smooth power transmission. During rotation, the ball screw converts rotational motion into linear motion through the nut seat, driving the connected converter module 500 to move up and down, enabling the bonding head 600 to move closer to or further away from the flexible circuit board in the vertical direction. The third servo motor also serves as a power source, providing rotational power to the internal rotating structure of the converter module 500 via the driven gear set in the gear drive device. When it is necessary to switch bonding heads 600, the controller sends a command to the third servo motor, which drives the driven gear set to rotate, causing the rotating shaft to rotate. The rotating shaft is fixedly connected to the turntable 510, causing the turntable 510 to rotate accordingly, sequentially rotating different bonding heads 600 to their working positions. The turntable 510 and the bonding head 600 are set at a 90° angle to ensure that the bonding head 600 is vertically aligned with the flexible circuit board after rotating into position. The bearing assembly is mounted on the rotating shaft, with its inner and outer rings fixed to the rotating shaft and the frame respectively. This supports the rotating shaft while reducing friction and wobbling during rotation, ensuring the stability and positioning accuracy of the turntable 510. The positioning pin plays a crucial role during the bonding head 600 switching process. The cylindrical pin is located on the turntable 510 or the rotator frame, with its positioning hole located within the ball screw module 400. When the turntable 510 rotates the target bonding head 600 into position, the cylindrical pin precisely aligns with the positioning hole. As the ball screw module 400 descends, the cylindrical pin inserts into the positioning hole, achieving precise coaxial positioning of the bonding head 600 and the screw module. Simultaneously, quick-connect couplings automatically engage, with their male and female ends installed on the screw module and bonding head 600 respectively, ensuring stable power transmission.

[0062] In some embodiments, before the flexible circuit board multi-head rotary switching device operates, a laser concave sensor installed in the converter module 500 scans the surface of the flexible circuit board, transmitting data such as concavity / uncavity and thickness to the controller. The controller then adjusts the pressing stroke and pressure parameters of the bonding head 600. A photoelectric sensor is positioned next to the flexible circuit board to monitor its positioning in real time. When the flexible circuit board enters the sensing range, the photoelectric sensor sends a signal back to the controller, triggering the reinforcement process. During the operation phase, the vacuum nozzle integrated into the bonding head 600 opens, using negative pressure to adsorb the reinforcement material. The bonding head 600 descends vertically under the push of the ball screw module 400. A pressure sensor monitors the pressure value during the pressing process in real time and sends the data back to the controller. If the pressure deviates from the set value, the controller immediately adjusts the output of the second servo motor 200 to precisely control the pressing force and stroke of the ball screw module, ensuring a tight fit between the reinforcement material and the flexible circuit board. After bonding is completed, the vacuum nozzle closes, the first servo motor 100 drives the lead screw module to lift and reset the bonding head 600, and the second servo motor 200 drives the turntable 510 to rotate, switching to the next bonding head 600, waiting to perform the next reinforcement task.

[0063] In some embodiments, a heating device is provided in a plurality of adhesive heads 600 for heating the reinforcing material that needs to be heated and bonded, and at the same time, the pressure of the adhesive heads 600 on the reinforcing material makes the bonding of the reinforcing material tighter and more secure.

[0064] In some embodiments, the position of the ball screw's fluctuation range (high and low) is marked by a simulated operation method, and a sensor card is installed. A laser concave sensor is installed on the frame at the same position. The sensor card is finely adjusted by reinforcing the quality. When the sensor card enters the laser concave sensor during operation, it sends a signal to the ball screw. The trigger signal causes the ball screw to move up and down at the marked point to verify the sensitivity of the laser concave sensor and the compatibility of the equipment software, ensuring that the ball screw's up and down fluctuation does not exceed the marked range during equipment operation.
