Description

Technical Field

[0001] This utility model relates to the field of screen PCB flipping technology, specifically to a screen PCB flipping device. Background Technology

[0002] During the screen manufacturing process, the flexible PCB board needs to be glued to the back of the screen glass. This process requires folding the flexible PCB board to the back of the screen glass.

[0003] For example, Chinese utility model patent CN218041946U discloses a semi-flexible PCB board carrier, including a frame and a folding device, a positioning device, and an adsorption device disposed on the frame. The folding device includes a folding plate with a folding surface on one side for placing the flexible PCB board to be folded. The adsorption device is disposed at the folding plate and adsorbs the flexible PCB board located on the folding surface. The positioning device is located below the folding plate to achieve folding positioning of the flexible PCB board to be folded. By using the positioning device to position the flexible PCB board to be folded, then using the adsorption device to adsorb and position the flexible PCB board, and then using the folding device to fold the flexible PCB board to be folded through the folding plate, the flexible PCB board can be precisely bent.

[0004] The aforementioned semi-flexible PCB carrier has certain limitations: the folding part of the folding plate is pivotally connected to the fixing part. When the folding part rotates around the pivot to complete the folding action of the flexible PCB, the edge of the folding part near the pivot position is prone to contact or be squeezed with the screen surface supported on the fixing part, which can easily affect the production quality of the screen. Utility Model Content

[0005] In view of the above-mentioned technical problems in the existing technology, this utility model provides a screen PCB board folding device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A screen PCB board folding device is provided, including a screen moving module and a PCB board folding module located above it. The PCB board folding module includes a mounting frame, a first X-axis drive mechanism, and a folding arm. The first X-axis drive mechanism is fixed to the top of the mounting frame and is drivenly connected to the folding arm. The folding arm includes a first connecting plate, a Y-axis drive mechanism, a first Z-axis drive mechanism, and a folding component. The Y-axis drive mechanism is fixed to the top of the first connecting plate. The first Z-axis drive mechanism is drivenly connected to the Y-axis drive mechanism, and the folding component is drivenly connected to the first Z-axis drive mechanism. The folding component is used to adsorb the PCB board and drive the PCB board to fold. The Y-axis drive mechanism and the first Z-axis drive mechanism cooperate to drive the folding component to move back and forth between the bottom of the PCB board and the back of the screen glass surface.

[0007] Preferably, the folding assembly includes a connecting frame, and the bottom of the connecting frame is rotatably provided with a folding rod arranged along the length of the connecting frame. The surface of the folding rod is provided with multiple suction nozzles for adsorbing PCB boards.

[0008] Preferably, the folding arm also includes a rotating shaft, which is connected to the Z-axis drive mechanism via a connecting block. The output end of the rotating shaft faces the folding assembly, and its output end is fixedly connected to the connecting frame.

[0009] Preferably, the screen moving module includes a linear motor and a feeding plate, the linear motor is arranged along the Y-axis, and the feeding plate is slidably disposed on top of the linear motor.

[0010] Preferably, the top of the feed plate is provided with multiple vacuum suction holes for adsorbing the screen.

[0011] Preferably, the PCB board reversing device further includes visual guidance components for providing visual guidance to the folding arm. Two visual guidance components are slidably disposed on the top of the mounting frame and located on both sides of the folding arm; a visual guidance component moving device and a visual camera fixed to the moving device. Preferably, the moving device includes a second X-axis drive mechanism, a second connecting plate, and a second Z-axis drive mechanism. The second X-axis drive mechanism is fixedly mounted on the top of the mounting frame. The connecting plate is drivenly connected to the second X-axis drive mechanism. The second Z-axis drive mechanism is fixedly connected to the side of the connecting plate. The vision camera is drivenly connected to the second Z-axis drive mechanism.

[0012] The beneficial effects of this utility model are: This invention discloses a screen PCB board folding device. By setting a folding arm, when the folding component in the folding arm moves to the bottom of the PCB board, the folding component can adhere to the bottom of the PCB board and simultaneously drive the PCB board to fold. Under the coordinated drive of the first Z-axis drive mechanism and the Y-axis drive mechanism, the PCB board is finally folded to the back of the screen glass surface. In the prior art, folding devices rely on the folding part rotating around a fixed pivot point. The edge of the folding part is prone to contact and pressure with the screen surface, which can cause scratches or pressure damage to the screen. In this device, the folding arm does not directly contact the screen throughout the entire folding process, thus avoiding damage to the screen caused by the folding arm during the folding of the PCB board.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] This embodiment provides a screen PCB board flipping device, such as... Figures 1 to 2 As shown, it includes a screen moving module and a PCB board folding module located above it. The moving module is used to move the screen to below the PCB board folding module, and then the PCB board on the screen is folded by the PCB board folding module.

[0021] Combination Figure 3 As shown, the screen moving module includes a linear motor 1 and a conveyor plate 2. The linear motor 1 is arranged along the Y-axis, while the conveyor plate 2 is slidably mounted on top of the linear motor 1 and is connected to the linear motor 1 for transmission. The top of the conveyor plate 2 has multiple vacuum suction holes for adsorbing the screen. This design uses the suction force of the vacuum suction holes to firmly fix the screen on the conveyor plate 2, preventing the screen from shifting or shaking during transport due to vibration, start-stop, or other factors, while also ensuring stability during subsequent PCB board flipping processes.

[0022] It should be noted that linear motor 1 is existing technology, and its specific principle is the same as that of existing technology, so it will not be elaborated here.

[0023] Combination Figure 1 , Figure 2 and Figure 4As shown, the PCB board folding module includes a mounting frame 3, a first X-axis drive mechanism 4, and a folding arm 5. The first X-axis drive mechanism 4 is fixedly mounted on the top of the mounting frame 3, and the folding arm 5 is connected to the first X-axis drive mechanism 4 for transmission. The first X-axis drive mechanism 4 is used to drive the folding arm 5 to move along the X-axis direction.

[0024] The folding arm 5 includes a first connecting plate 50, a Y-axis drive mechanism 51, a first Z-axis drive mechanism 52, and a folding assembly 53. The first connecting plate 50 is connected to the first X-axis drive mechanism 4. The Y-axis drive mechanism 51 is fixedly mounted on the top of the first connecting plate 50. The first Z-axis drive mechanism 52 is connected to the Y-axis drive mechanism 51. The folding assembly 53 is connected to the first Z-axis drive mechanism 52. As can be seen from the above, the folding assembly 53 can move along the X, Y, and Z axes under the drive of the first X-axis drive mechanism 4, the Y-axis drive mechanism 51, and the first Z-axis drive mechanism 52.

[0025] The folding assembly 53 includes a connecting frame 530 and a folding rod 531. The connecting frame 530 is connected to the first Z-axis drive mechanism 52. The folding rod 531 is rotatably located at the bottom of the connecting frame 530 along its length. The surface of the folding rod 531 is provided with multiple suction nozzles for adsorbing PCB boards (not shown in the figure).

[0026] In use, after the screen moving module moves the screen to below the PCB board folding module, the first Z-axis driving mechanism 52 drives the folding component 53 to move down to a position below the screen PCB board. Then, the suction cup on the folding rod 531 adheres to the bottom of the PCB board. After the suction cup adheres to the bottom of the PCB board, the folding rod 531 starts to rotate, causing the PCB board to rotate together, so that the PCB board can be flipped. At the same time, during the flipping process of the folding rod 531, the first Z-axis driving mechanism 52 and the Y-axis driving mechanism 51 move together to move the folding component 53 to the top of the screen. Finally, the first Z-axis driving mechanism 52 drives the folding component 53 to move down, causing the folded PCB board to move down and stick to the back of the screen glass.

[0027] It should be noted that the first X-axis drive mechanism 4, the Y-axis drive mechanism 51 and the first Z-axis drive mechanism 52 are all existing technologies, and their specific principles are the same as those of existing technologies, so they will not be elaborated here.

[0028] Furthermore, the folding arm 5 also includes a rotating shaft 54, which is connected to the first Z-axis drive mechanism 52 via a connecting block. The output end of the rotating shaft 54 ​​faces the folding assembly 53 and is fixedly connected to the connecting frame 530. By setting the rotating shaft 54, when the screen is tilted on the feed plate 2, it often causes the angle of the associated PCB board to shift. At this time, the rotating shaft 54 ​​will start in time, driving the folding rod 531 to rotate horizontally until the angle of the folding rod 531 is consistent with the angle of the PCB board. The rotating shaft 54 ​​is a drive motor, and the output end of the drive motor is fixedly connected to the connecting frame 530.

[0029] Combination Figure 1 , Figure 2 and Figure 5 As shown, the PCB board reversing device also includes a visual guidance component 6, which is used to provide visual guidance to the folding arm 5. Two visual guidance components 6 are slidably disposed on the top of the mounting frame 3 and located on both sides of the folding arm 5.

[0030] The visual guidance assembly 6 includes a moving device 60 and a visual camera 61 fixed to the moving device 60. The moving device 60 includes a second X-axis drive mechanism 601, a second connecting plate 602, and a second Z-axis drive mechanism 603. The second X-axis drive mechanism 601 is fixed to the top of the mounting bracket 3. The second connecting plate 602 is connected to the output end of the second X-axis drive mechanism 601, allowing the second connecting plate 602 to slide along the X-axis direction. The second Z-axis drive mechanism 603 is fixedly connected to the side of the second connecting plate 602. The visual camera 61 is connected to the output end of the second Z-axis drive mechanism 603, allowing it to move along the Z-axis direction under the drive of the second Z-axis drive mechanism 603.

[0031] In use, after the screen moving module moves the screen below the PCB board folding module, the visual guidance component 6 starts working. The second X-axis drive mechanism 601 first drives the second connecting plate 602, the second Z-axis drive mechanism 603, and the visual camera 61 to move along the X-axis direction, adjusting the shooting position of the visual camera 61 in the horizontal direction. Subsequently, the second Z-axis drive mechanism 603 drives the visual camera 61 to move along the Z-axis direction to adjust the shooting focal length and angle. After the visual camera 61 captures the position, angle, and other information of the PCB board, it feeds the information back to the folding arm 5 in real time. The folding arm 5 is adjusted according to the information fed back by the visual guidance component 6 and by the first X-axis drive mechanism 4, the Y-axis drive mechanism 51, and the first Z-axis drive mechanism 52, so that the folding arm 5 can accurately connect with the PCB board, thereby improving the accuracy and stability of the folding operation.

[0032] It should be noted that the second X-axis drive mechanism 601 and the second Z-axis drive mechanism 603 are both existing technologies, and their specific principles are the same as those of existing technologies, so they will not be elaborated here.
