Description

Technical Field

[0001] This invention relates to the field of flexible circuit board processing technology, and more specifically to a flexible circuit board processing equipment capable of automatically correcting its position. Background Technology

[0002] Flexible circuit boards (PCBs) are favored for their excellent properties such as light weight, thinness, and ability to be freely bent and folded. In electronic devices, PCBs are often used to connect different modules. Their ability to be completely folded greatly facilitates the integration of different modules in electronic devices. Because they need to connect multiple modules, the shape of PCBs is mostly irregular. Flexible circuit board processing equipment is used in the processing of PCBs. This equipment can assemble electronic components onto the PCBs. Existing flexible circuit board processing equipment, such as the flexible circuit board processing fixing device disclosed in patent number CN111447746B, uses two sliders to fix the flexible circuit board. However, the two sliders can only fix long and narrow flexible circuit boards, and do not have a good fixing effect on most irregular flexible circuit boards. Therefore, there is a need for flexible circuit board processing equipment that can automatically correct the position and fix irregular flexible circuit boards during processing. Summary of the Invention

[0003] To overcome the aforementioned technical problems, the present invention aims to provide a flexible circuit board processing device with automatic position correction. Through a limiting mechanism, when fixing a flexible circuit board, the positions of the sliding rod and the limiting electromagnet can be adjusted according to the irregular shape of the flexible circuit board, so that the limiting electromagnet is positioned at the corner of the flexible circuit board. Combined with an iron block, it can fix flexible circuit boards of different specifications, improving applicability. Through a release mechanism, automatic contact fixing of the flexible circuit board is achieved, fitting into automated production lines and improving work efficiency.

[0004] The objective of this invention can be achieved through the following technical solutions: A flexible circuit board processing device capable of automatically correcting its position, comprising: The equipment base has a support column fixedly connected to its top surface, a support frame fixedly connected to one side of the support column, and a horizontal track provided on the top surface of the equipment base. An automatic straightening supply wheel is rotatably mounted on the top surface of the equipment base; An automatic straightening assembly wheel is provided on the inner side of the support column. The automatic straightening assembly wheel is used to grip the electronic components on the top surface of the automatic straightening supply wheel and assemble them onto the flexible circuit board. A limiting mechanism is slidably disposed on the inner side of the horizontal track, and the limiting mechanism is used to fix the flexible circuit board; A release mechanism is movably disposed on the front side of the support frame. The release mechanism is used to release the limiting mechanism from fixing the flexible circuit board.

[0005] As a further aspect of the present invention: the top edge of the automatic correction supply wheel is provided with a plurality of cylindrical slots for placing electronic components. The cylindrical slots are arranged in an annular shape at equal intervals. The cylindrical slots can also be replaced with rectangular slots. The main function is to place electronic components and fit the shape of the electronic components.

[0006] As a further aspect of the present invention: the side of the automatic straightening assembly wheel is provided with a plurality of equally spaced cylindrical tubes, and a vacuum suction cup is provided inside the cylindrical tubes for gripping electronic components. A rotating seat is installed on the back of the automatic straightening assembly wheel, and a hydraulic cylinder is installed on the top surface of the rotating seat for adjusting the height of the automatic straightening assembly wheel. A horizontal sliding rod is fixedly connected to the front of the hydraulic cylinder, and a track rod that matches the horizontal sliding rod is fixedly connected to the top of the support column.

[0007] As a further aspect of the present invention: a threaded rod is mounted on one end of the support frame via a bearing, a limiting rod is provided on the other end of the support frame, and a drive motor is bolted to the top surface of the support frame near the threaded rod. The output shaft of the drive motor is connected to the threaded rod via a coupling.

[0008] As a further embodiment of the present invention: the limiting mechanism includes a movable seat, which fits into a horizontal track. A movable groove is provided at the middle position of the top surface of the horizontal track. A nut is bolted to the middle position of the bottom surface of the movable seat. A lead screw is installed at the bottom of the horizontal track near the nut via a bearing. The nut is nested on the outside of the lead screw and cooperates with it. The movable groove is used to cooperate with the nut, so that the nut can move at the top of the horizontal track. The lead screw and nut can also be replaced by an electric push rod, a hydraulic push rod, or a pneumatic push rod.

[0009] As a further aspect of the present invention: the top surface of the movable seat is provided with an adjustment cavity, and multiple sliding rods are provided inside the adjustment cavity. Sliding limiting electromagnets are nested on the sides of the sliding rods. Toggle blocks are fixedly connected to both ends of the sliding rods. A transparent plate is provided at the port of the adjustment cavity. The transparent plate is made of resin or tempered glass to facilitate observation of the position of the limiting electromagnets inside the adjustment cavity.

[0010] As a further aspect of the present invention: the release mechanism includes a lifting frame, a ball nut is fixedly connected to the end face of the lifting frame near the threaded rod, and the ball nut is nested on the outside of the threaded rod. A limiting sleeve that fits with the limiting rod is fixedly connected to the end face of the lifting frame near the limiting rod. Multiple moving rods are provided on the inner side of the lifting frame. A sliding release electromagnet is nested on the side of the moving rod. An iron block is attracted to the bottom surface of the release electromagnet.

[0011] As a further aspect of the present invention, a thin film is nested on the outside of the iron block, and the thin film serves as a buffer and isolation layer.

[0012] The beneficial effects of this invention are: 1. In this invention, by setting a limiting mechanism, when fixing a flexible circuit board, the positions of the sliding rod and the limiting electromagnet can be adjusted according to the irregular shape of the flexible circuit board, so that the limiting electromagnet is located at the corner of the flexible circuit board. With the help of the iron block, flexible circuit boards of different specifications can be fixed, thus improving applicability.

[0013] 2. In this invention, through the set release mechanism, after the flexible circuit board is processed, the circuit of the release electromagnet is opened and the limit electromagnet is closed at the same time. At this time, the magnetic field of the limit electromagnet disappears, while the release electromagnet generates a magnetic field that can attract the iron block. When the lifting frame rises, it can drive the iron block to rise, causing the iron block to detach from the flexible circuit board, thus releasing the fixation of the flexible circuit board. This realizes the automatic contact fixation of the flexible circuit board, which fits the automated production line and improves work efficiency. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] like Figures 1-6 As shown, a flexible circuit board processing device with automatic position correction is disclosed. The device includes a base 1, with two sets of support columns 3 bolted to the top surface of the base 1. A sliding automatic correction assembly wheel 4 is installed between the two sets of support columns 3. A rotatable automatic correction supply wheel 2 is installed at the front end of the top surface of the base 1. A rotating base 13 is located on the bottom surface of the base 1 near the bottom surface of the automatic correction supply wheel 2, enabling the automatic correction supply wheel 2 to rotate automatically. Multiple flexible circuit boards are placed on the top surface of the automatic correction supply wheel 2. The electronic components used in the flexible circuit board are automatically picked up by the automatic straightening assembly wheel 4. After the electronic component is picked up by the automatic straightening assembly wheel 4, the automatic straightening supply wheel 2 can automatically straighten its position by rotating, so that the next electronic component is in the picked position. The side of the automatic straightening assembly wheel 4 can hold multiple electronic components at the same time. After the automatic straightening assembly wheel 4 assembles the electronic component onto the top surface of the flexible circuit board, it can also automatically straighten its position by rotating, so as to ensure that the electronic components can be continuously transferred onto the flexible circuit board. The top edge of the automatic straightening supply wheel 2 has multiple cylindrical slots for placing electronic components. The cylindrical slots are arranged in an annular shape at equal intervals. The rotating base 13 is driven by a motor. By rotating the base 13, the rotation angle of the automatic straightening supply wheel 2 can be adjusted, thus realizing the automatic straightening of the position of the automatic straightening supply wheel 2. The side of the automatic straightening assembly wheel 4 has multiple cylindrical tubes arranged at equal intervals. Vacuum suction cups can be installed inside the cylindrical tubes for gripping electronic components. A rotating seat is installed on the back of the automatic straightening assembly wheel 4. A hydraulic cylinder is installed on the top surface of the rotating seat for adjusting the height of the automatic straightening assembly wheel 4. A motor is installed inside the rotating seat to control the rotation angle of the automatic straightening assembly wheel 4, so that the automatic straightening assembly wheel 4 can automatically straighten its position. A horizontal sliding rod is also fixedly connected to the front of the hydraulic cylinder. The top of the support column 3 is fixedly connected to a track rod 31 that matches the horizontal sliding rod, ensuring that the horizontal sliding rod can slide along the horizontal longitudinal direction.

[0019] like Figure 1 and Figure 2 As shown, a support frame 5 is fixedly connected to the side of one set of support columns 3. The front of the support frame 5 is provided with an automatically lifting release mechanism 7. A horizontal track 11 is provided on the top surface of the equipment base 1 near the release mechanism 7. A limiting mechanism 6 that can slide horizontally is provided in the horizontal track 11. The top surface of the limiting mechanism 6 is used to place the flexible circuit board and can limit the position of the flexible circuit board. When the automatic straightening assembly wheel 4 is assembling electronic components on the flexible circuit board, the limiting mechanism 6 can keep the flexible circuit board stable. After the electronic components on the flexible circuit board are assembled, the release mechanism 7 can automatically release the limiting mechanism 6 from the flexible circuit board. No manual operation is required, which is highly efficient.

[0020] like Figure 4 As shown, a threaded rod 52 is mounted on one end of the support frame 5 via a bearing, and a limit rod 53 is provided on the other end of the support frame 5. A drive motor 51 is bolted to the top surface of the support frame 5 near the threaded rod 52. The output shaft of the drive motor 51 is connected to the threaded rod 52 via a coupling. When the drive motor 51 is working, the drive motor 51 can drive the threaded rod 52 to rotate via the coupling.

[0021] like Figure 5As shown, the limiting mechanism 6 includes a movable seat 61, which cooperates with the horizontal track 11. A movable groove 12 is provided in the middle of the top surface of the horizontal track 11. A nut is bolted to the middle of the bottom surface of the movable seat 61. A lead screw is installed at the bottom of the horizontal track 11 near the nut via a bearing. The lead screw is driven by a motor. The nut is nested on the outside of the lead screw and cooperates with it. An adjustment cavity 62 is provided in the top surface of the movable seat 61. Multiple sliding rods 63 are provided in the adjustment cavity 62. A sliding limiting electromagnet 65 is nested on the side of the sliding rod 63. A lever 64 is fixedly connected to both ends of the sliding rod 63. A detachable transparent plate is installed at the port of the adjustment cavity 62.

[0022] like Figure 6 As shown, the release mechanism 7 includes a lifting frame 71. A ball nut 72 is fixedly connected to the end face of the lifting frame 71 near the threaded rod 52, and the ball nut 72 is nested on the outside of the threaded rod 52. When the threaded rod 52 rotates, the ball nut 72 can move up and down on the side of the threaded rod 52. Since the ball nut 72 is fixedly connected to the lifting frame 71, the ball nut 72 can drive the lifting frame 71 to move up and down. A limiting sleeve 73 that matches the limiting rod 53 is fixedly connected to the end face of the lifting frame 71 near the limiting rod 53. Multiple moving rods 74 are provided on the inner side of the lifting frame 71. A sliding release electromagnet 75 is nested on the side of the moving rod 74. An iron block 76 is attracted to the bottom surface of the release electromagnet 75. A thin film is nested on the outside of the iron block 76. When the iron block 76 is pressed on the top surface of the flexible circuit board, the thin film can play a buffering and isolation role.

[0023] like Figures 4-6 As shown, since the flexible circuit board has an irregular shape, the position of the sliding rod 63 can be adjusted by the toggle block 64, and then the position of the limiting electromagnet 65 on the side of the sliding rod 63 can be adjusted so that the limiting electromagnet 65 can be located at the corner of the flexible circuit board. Similarly, the position of the moving rod 74 and the release electromagnet 75 can be adjusted so that the position of the release electromagnet 75 corresponds one-to-one with the position of the limiting electromagnet 65. Then, the lifting frame 71 is lowered. When the bottom surface of the iron block 76 contacts the flexible circuit board, the circuit of the release electromagnet 75 can be turned off, and the circuit of the limiting electromagnet 65 can be turned on. The magnetic field of the release electromagnet 75 disappears, while the limiting electromagnet 65 generates a magnetic field that can attract the iron block 76, so that the iron block 76 is pressed against the top surface of the flexible circuit board, thereby fixing the flexible circuit board. After the flexible circuit board is processed, the circuit of the release electromagnet 75 is turned on, and the limit electromagnet 65 is turned off. At this time, the magnetic field of the limit electromagnet 65 disappears, while the release electromagnet 75 generates a magnetic field that can attract the iron block 76. When the lifting frame 71 rises, it can drive the iron block 76 to rise, so that the iron block 76 is separated from the flexible circuit board, thus releasing the fixation of the flexible circuit board and making it easier to replace the new flexible circuit board for processing.

[0024] Working principle of the invention: Adjust the positions of the limiting electromagnet 65 and the releasing electromagnet 75 according to the shape of the flexible circuit board, so that the limiting electromagnet 65 is at the corner of the flexible circuit board. Then place the flexible circuit board on the transparent plate on top of the moving seat 61, and then turn on the drive motor 51. The drive motor 51 can drive the threaded rod 52 to rotate through the coupling. The threaded rod 52 can make the outer ball nut 72 descend. Since the ball nut 72 is fixedly connected to the lifting frame 71, the ball nut 72 can drive the lifting frame 71 to move downward. When the bottom surface of the iron block 76 contacts the flexible circuit board, the circuit of the release electromagnet 75 is closed, and the circuit of the limit electromagnet 65 is opened. The magnetic field of the release electromagnet 75 disappears, while the limit electromagnet 65 generates a magnetic field, which attracts the iron block 76, causing the iron block 76 to press against the top surface of the flexible circuit board, thus fixing the flexible circuit board. Turn on the motor at the bottom of the horizontal track 11. The motor drives the lead screw, which drives the moving seat 61 through the nut. The moving seat 61 moves along the direction of the horizontal track 11 and moves to directly below the automatic straightening assembly wheel 4. The automatic straightening assembly wheel 4 can install electronic components onto the top surface of the flexible circuit board. After the flexible circuit board is assembled, drive the moving seat 61 again to return it to the bottom of the release mechanism 7. Move the lifting frame 71. When the bottom surface of the release electromagnet 75 contacts the top surface of the iron block 76, turn on the circuit of the release electromagnet 75 and turn off the limit electromagnet 65. At this time, the magnetic field of the limit electromagnet 65 disappears, while the release electromagnet 75 generates a magnetic field that can attract the iron block 76. When the lifting frame 71 rises, it can drive the iron block 76 to rise, so that the iron block 76 is separated from the flexible circuit board, thus releasing the fixation of the flexible circuit board and facilitating the replacement of a new flexible circuit board for processing.
