Description

Technical Field

[0001] This utility model relates to the field of circuit board processing monitoring technology, specifically a circuit board device capable of online monitoring of processing status. Background Technology

[0002] A circuit board, or printed circuit board (PCB), is the core carrier that holds and connects electronic components in electronic devices. It uses an insulating substrate (such as epoxy resin) to isolate the conductive copper foil layer on its surface, guiding current to flow between components along a designed path to achieve signal transmission and functional operations (such as amplification and modulation). It forms the "neural network skeleton" of electronic devices. As the core carrier of electronic devices, the processing precision of the circuit board directly determines the product's performance and reliability. In critical processes such as soldering, mounting, and drilling, problems such as component misalignment, solder joint defects, and board deformation must be prevented through real-time monitoring throughout the entire process to avoid defective products flowing downstream.

[0003] However, existing circuit board processing monitoring technologies have significant limitations, making it difficult to meet the monitoring requirements of "full range, multi-angle, and high precision." Traditional monitoring equipment often relies on a single vision component in a fixed position, which can only inspect a local area of ​​the circuit board (such as the central soldering area), failing to achieve 360° full surface coverage of the entire board. When dealing with edge components and hidden solder joints of irregularly shaped boards and flexible boards, it is easy to miss hidden defects such as cold solder joints and short circuits in small circuits due to blind spots, leading to defective products being shipped out. At the same time, the angle and position of the monitoring component are relatively fixed, making it difficult to adapt to different circuit board shapes. For example, when detecting bonding defects in curved flexible printed circuit boards (FPCs) or warpage in multilayer laminated boards, the fixed angle cannot match the board shape, resulting in distorted detection parameters. For circuit boards of different sizes, such as small PCBs and large industrial control boards, it is necessary to replace them with dedicated monitoring accessories, increasing costs and changeover time. Therefore, those skilled in the art have provided a circuit board device that can monitor the processing status online to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a circuit board device capable of online monitoring of the processing status, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circuit board device capable of online monitoring of processing status includes a main body, an annular support, a guide rail, and a vision monitoring component. The annular support is positioned above the main body, and a driven gear is rotatably connected to the annular support. A fixing plate is positioned on the right side of the main body and is fixedly connected to it. A first servo motor is mounted on the upper end of the fixing plate, and a first rotating shaft is fixedly connected to the power output end of the first servo motor. A driving gear is mounted on the outer wall of the first rotating shaft, meshing with the driven gear. A through-hole is formed at the center of the driven gear, and a guide rail is mounted on the inner wall of the through-hole, with the guide rail fixedly connected to the driven gear. On the moving gear, a second servo motor is fixedly mounted on the upper end of the guide rail. A second threaded rod is fixedly connected to the power output end of the second servo motor. The second threaded rod is actively connected to the guide rail. A slider is threadedly connected to the second threaded rod. A first connector is provided at the front end of the slider. The first connector is rotatably connected to the slider. A connecting rod is provided at the front end of the first connector. The first connector and the connecting rod are fixedly connected together. A second connector is provided at the front end of the connecting rod. The second connector and the connecting rod are fixedly connected together. A vision monitoring component is provided at the front end of the second connector. The vision monitoring component is fixedly connected to the second connector.

[0007] As a further embodiment of this utility model: the visual monitoring component includes a high-definition industrial camera and a 3D structured light scanner, wherein the high-definition industrial camera is used to capture images of the circuit board after processing, and the 3D structured light scanner is used to detect the component mounting height difference and the circuit board warpage.

[0008] As a further embodiment of this utility model: the guide rail is provided with a sliding groove, wherein the slider is locked in the sliding groove, and side plates are provided on both the left and right sides of the guide rail, wherein the side plates are fixedly connected to the guide rail, and each side plate is provided with a movable groove. The second connecting member is fixedly connected to movable shafts on both the left and right sides, wherein the movable shafts are movably connected in the movable grooves and can move back and forth in the movable grooves.

[0009] As a further embodiment of this utility model: an annular groove is provided on the inner wall of the annular bracket, and a protruding ring is fixedly connected to the lower end of the driven gear, wherein the protruding ring is engaged in the annular groove and can rotate within the annular groove.

[0010] As a further embodiment of this utility model: the lower end of the annular bracket is fixedly connected to two support plates on the left and right, wherein the bottom of the support plates is fixedly connected to the main body of the device, and the first servo motor is bolted to the annular bracket and the right support plate of the annular bracket. Locking casters are bolted to the four corners at the lower end of the main body of the device. A transmission assembly is fixedly installed at the upper end of the main body of the device, and a controller is fixedly installed on the right side of the fixed plate, wherein the controller is electrically connected to the main body of the device.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. 360° full-range circular monitoring, eliminating blind spots: With the help of the rotary transmission structure of "first servo motor + driving gear + driven gear", the visual monitoring component can achieve 360° circular scanning around the circuit board (the driven gear drives the guide rail to rotate, and the monitoring component moves in circumferentially). This can solve the problem of "partial detection and missed edge components / hidden solder joints" of traditional fixed cameras. Even when facing irregularly shaped boards and flexible boards (such as curved FPC and multi-layer laminated boards), it can accurately capture hidden defects such as cold solder joints and short circuits in small lines.

[0013] 2. Dynamic Angle Adaptation, Compatible with Multiple Circuit Board Form Factors: Through the linkage mechanism of "second servo motor + threaded rod + slider + movable shaft", the visual monitoring component can flexibly adjust the tilt angle. The second servo motor drives the threaded rod to rotate, which in turn moves the slider along the guide rail groove. The linkage connecting rod and movable shaft (adjusted back and forth along the movable groove of the side plate) achieve dynamic adaptation of the monitoring angle. Regardless of whether the circuit board is a small PCB, a large industrial control board, or a rigid board / flexible board / irregularly shaped stacked board, the angle can be adjusted to match the board shape (such as detecting bonding defects of curved FPCs or warpage of multilayer boards), adapting to various types of circuit boards without the need to customize dedicated equipment for different board types.
