Description

Technical Field

[0001] This utility model relates to the field of PCB flexible board processing technology, specifically to an automatic bending device for PCB flexible boards. Background Technology

[0002] Bending is a common and important process in the fabrication of PCB (Printed Circuit Board) flexible boards, especially when a 180° bend is required. While traditional manual or semi-automatic bending equipment can perform this process, it has certain shortcomings, mainly in terms of low production efficiency, inconsistent bending quality, and high operational difficulty.

[0003] Existing bending equipment is mostly based on a single mechanical manual or semi-automatic operating system. Operators need to rely on manual experience for precise operation and adjustment, which is obviously inefficient for complex bending processes and the needs of mass production. In addition, the control methods of traditional equipment are relatively primitive, often unable to achieve precise angle control and speed adjustment. This results in inconsistent bending angles and bending quality for each flexible board, thus affecting the overall product quality and reliability.

[0004] Currently, with the miniaturization and thinning of electronic products and the increasing demand for PCB flexible board bending, traditional manual and semi-automatic bending methods can no longer meet the high efficiency and high precision requirements of modern production. In order to improve production efficiency, reduce labor costs, and ensure product quality, the industry's demand for automated, efficient, and precise PCB flexible board bending equipment is increasing day by day.

[0005] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop an automatic PCB flexible board bending device. Utility Model Content

[0006] The purpose of this invention is to provide an automatic bending device for flexible PCB boards to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A technical solution for an automatic PCB flexible board bending device includes a frame, a PCB board carrier mounted on the frame, and a bending execution mechanism mounted on the frame.

A PCB flexible board pressing steel sheet is provided on the PCB board carrier. The bending blade assembly is connected to the frame through a front-rear motion module and a front-rear motion seat.

[0008] As a preferred technical solution, the visual positioning system is used to identify the position of the PCB flexible board and adjust the position of the folding blade assembly through the front and rear motion module.

[0009] As a preferred technical solution, the lifting mechanism is used to pre-fold the PCB flexible board to a certain angle, and the rolling module is used to roll the PCB flexible board to the target angle.

[0010] As a preferred technical solution, the lifting module drives the folding blade to press down to fix the bending position of the PCB flexible board.

[0011] As a preferred technical solution, the rolling module rolls the PCB flexible board to a 180° bent state through reciprocating motion.

[0012] As a preferred technical solution, the front and rear motion module and the lifting module are electrically driven modules to achieve precise position control.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by integrating a vision positioning system, an automatic bending knife assembly and a rolling module, the PCB flexible board bending process is realized, which greatly improves production efficiency and bending accuracy, avoids the quality instability problem of traditional manual operation, and ensures the consistency of bending angle.

[0014] By employing the coordinated operation of a lifting mechanism and a rolling module, the bending angle can be precisely controlled (such as 180° bending), and springback is eliminated through reciprocating rolling, ensuring the reliability of bending quality and product consistency. At the same time, it reduces the difficulty of operation and labor costs, adapting to the production needs of modern electronic products for miniaturization and thinning. Attached Figure Description

[0017] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for an automatic PCB flexible board bending device: including a frame 3, a PCB board carrier 1 mounted on the frame 3, and a bending execution mechanism mounted on the frame 3.

[0019] The PCB carrier 1 is fixedly connected to the workbench of the frame 3, and a PCB flexible board pressing steel sheet 11 is provided on it to fix the PCB flexible board to be bent.

[0020] The bending actuator includes a folding blade assembly and a rolling module 23. The folding blade assembly is connected to the frame 3 through a front and rear motion module 34 and a front and rear motion seat 35. The front and rear motion module 34 is an electric lead screw module, which is connected to the front and rear motion seat 35 through a coupling to realize the horizontal reciprocating motion of the folding blade assembly.

[0021] The folding knife assembly includes a folding knife holder 37 driven by a lifting module 36 and a folding knife 38 disposed on the folding knife holder 37. The lifting module 36 is an electric cylinder, and its piston rod is connected to the folding knife holder 37 through a floating joint to realize the vertical lifting and lowering movement of the folding knife 38.

[0022] The rolling module 23 includes a rolling base 24 and a rolling roller 25. The rolling base 24 is fixedly connected to the side plate of the frame 3, and the rolling roller 25 is rotatably connected to the rolling base 24 through a bearing. The surface of the rolling roller 25 is covered with an elastic rubber layer.

[0023] The device also includes a visual positioning system, which includes a visual camera 32 and a ring light source 33 mounted on a camera mount 31. The camera mount 31 is fixedly connected to the top crossbeam of the frame 3, and the visual camera 32 is connected to an external controller via a data cable.

[0024] The device has a base 2 at the bottom, and a lifting mechanism is provided on the base 2. The lifting mechanism includes a lifting air pipe 21 and a lifting block 22. The lifting air pipe 21 is connected to an external air source through a quick connector, and the lifting block 22 is slidably connected in the guide groove of the base 2.

[0025] The PCB flexible board to be bent is placed on the PCB board carrier 1, and the flexible board is pressed and fixed by the PCB flexible board pressing steel sheet 11.

[0026] The visual positioning system is activated, and the visual camera 32 captures a position image of the PCB flexible board under the illumination of the ring light source 33, and transmits the image data to the external controller.

[0027] The external controller processes the image, identifies the bending line position of the flexible board, and adjusts the horizontal position of the folding blade assembly through the forward and backward motion module 34 so that the folding blade 38 is aligned with the bending line.

[0028] When the lifting mechanism is activated, compressed air enters the cylinder chamber below the lifting block 22 through the lifting air pipe 21, pushing the lifting block 22 to rise and pre-bend the PCB flexible board to a set angle (such as 90°).

[0029] When the lifting module 36 is activated, the piston rod of the electric cylinder extends, pushing the folding knife seat 37 and the folding knife 38 to descend. The folding knife 38 presses into the bending line of the flexible board, fixing the bending position.

[0030] Start the rolling module 23. The rolling roller 25 reciprocates under electric drive to roll the pre-bent soft board and gradually roll the soft board to the target angle (such as 180°).

[0031] During the rolling process, the elastic rubber layer of the rolling roller 25 makes full contact with the surface of the soft board. The springback of the soft board is eliminated by repeated rolling, ensuring the accuracy of the bending angle.

[0032] After the rolling process is completed, the lifting module 36 drives the folding blade 38 to rise and reset, and the lifting mechanism drives the lifting block 22 to fall and reset, releasing the PCB flexible board pressing steel sheet 11 and taking out the bent PCB flexible board.

[0033] By repeating the above steps, continuous automated bending processing of PCB flexible boards can be achieved.

[0034] By integrating a vision positioning system, an automatic bending knife assembly, and a rolling module, the PCB flexible board bending process is automated, significantly improving production efficiency and bending accuracy. This avoids the quality instability issues associated with traditional manual operation and ensures consistent bending angles. The coordinated operation of the lifting mechanism and rolling module allows for precise control of the bending angle (e.g., 180° bending), and reciprocating rolling eliminates springback, guaranteeing reliable bending quality and product consistency. Simultaneously, it reduces operational difficulty and labor costs, meeting the miniaturization and thinning demands of modern electronic products.
