Description

Technical Field

[0001] The utility model relates to the field of PCB board production, in particular to a continuous laser coding device for PCB boards with accurate positioning. Background Art

[0002] In the process of PCB production, information such as raw material procurement, production process and technology, product batch, manufacturer, production date, and product destination needs to be automatically generated into two-dimensional codes and then laser-automatically marked on the surface of the PCB board, so as to realize the control and traceability of product quality.

[0003] At present, PCB coding is mainly completed by the cooperation of manual labor and laser coding equipment. After manually adjusting parameters such as the position of the laser coder, the operator places the PCB board on the coding station for laser coding and then takes it out to place the next PCB board. Compared with the original manual coding, this coding method not only improves the coding efficiency but also makes the coding position more accurate. However, it still cannot meet the requirements of large-volume coding work, and there are certain errors when different operators adjust the parameters of the laser generator, which affects the coding quality. In addition, laser coding mainly uses a laser generator to generate a high-energy continuous laser beam, and then the laser beam is applied to the PCB through a laser coding head to instantaneously melt or vaporize the surface material on the PCB board. During the coding process, a certain amount of fumes will be generated, and long-term exposure by the operator is likely to cause damage to the body. Content of the Utility Model

[0004] Purpose of the Utility Model: The purpose of the utility model is to provide a continuous laser coding device for PCB boards with accurate positioning, which solves the problems existing in the laser coding process of existing PCB boards.

[0005] Technical solution: The utility model provides a PCB board continuous laser coding device with accurate positioning, including a frame, a conveying structure, a workbench structure, and a movable laser structure. The conveying structure is arranged on the frame. The workbench structure is arranged on the frame at the middle position of the conveying structure. The movable laser structure is arranged on the frame above the workbench structure. Among them, the conveying structure includes a conveyor belt structure, a first limiting structure, and a second limiting structure. The first limiting structure and the second limiting structure are oppositely arranged on both sides of the conveyor belt structure. The workbench structure includes a lifting table and a positioning structure. The positioning structure is arranged on the side of the lifting table. The movable laser structure includes a first horizontal movement structure, a second horizontal movement structure, and a laser coding structure. There are two groups of the first horizontal movement structures, which are arranged in parallel. The second horizontal movement structure is arranged on the first horizontal movement structure. The laser coding structure is arranged on the second horizontal movement structure. The PCB board is conveyed forward through the conveyor belt structure of the conveying structure. When it reaches the workbench structure, it is positioned by the positioning structure. At this time, the lifting table on the workbench structure rises to lift the PCB board on the conveyor belt structure to a specified height. The first limiting structure and the second limiting structure adjust the position of the PCB board. The laser coding structure in the movable laser structure performs laser coding work on the PCB board at a specified position under the drive of the first horizontal movement structure and the second horizontal movement structure. After the coding is completed, the lifting table descends, and the conveyor belt structure continues to convey the PCB board forward. Each structure cooperates with each other to complete the continuous coding work of the PCB board. Its operation is simple, the coding is accurate, and it is suitable for large-scale coding work of PCB boards.

[0006] Furthermore, the conveyor belt structure includes a support frame, a driving roller structure, a belt conveyor structure, and an auxiliary roller structure. The driving roller structure and the auxiliary roller structure are arranged in parallel at both ends of the support frame and are connected by the belt conveyor structure. The driving roller structure drives the belt conveyor structure to convey the PCB board placed on the belt of the belt conveyor structure under the support of the driving roller structure and the auxiliary roller structure, so as to facilitate the continuous progress of the laser coding work.

[0007] Furthermore, the first limiting structure and the second limiting structure have the same structure. The first limiting structure includes a first cylinder, a limiting plate, and a guiding structure. The plunger end of the first cylinder is connected to the limiting plate. There are two groups of the guiding structures, which are arranged in parallel on both sides of the limiting plate. When the PCB board reaches the specified position and is lifted by the workbench structure, the first cylinders of the first limiting structure and the second limiting structure drive the limiting plate to move along the guiding structure towards the PCB board, so as to adjust its position, thus ensuring the correctness of the subsequent laser coding position.

[0008] Further, the guiding structure includes a guide post, a guide sleeve, a limiting head, and a spring. The guide sleeve is arranged on the guide post, the limiting head is arranged at the end of the guide post, and the spring is arranged on the guide post between the guide sleeve and the limiting head. The guide sleeve is installed on the support frame, and the other end of the guide post away from the limiting head is installed on the limiting plate. When the first limiting structure and the second limiting structure perform the limiting action, under the action of the first cylinder, the limiting plate reciprocates along the guide sleeve through the guide post. The limiting head restricts the displacement range of the guide post, and the spring facilitates the tensioning and resetting functions.

[0009] Further, the lifting table includes a lifting structure and a workbench surface. The workbench surface is detachable, which not only facilitates replacement during maintenance but also allows for the replacement of a suitable workbench surface when laser marking different products.

[0010] Further, the positioning structure includes a second cylinder, a positioning plate, and guide blocks. The plunger end of the second cylinder is connected to the positioning plate, and there are two groups of guide blocks arranged side by side on both sides of the positioning plate. When the PCB board moves to the designated position along with the conveyor belt structure, the second cylinder drives the positioning plate upward along the guide blocks to position the PCB board, which facilitates the lifting table structure to lift the PCB board from the conveyor belt structure and perform laser marking at the designated position.

[0011] Further, the first horizontal movement structure includes a support and a first movement component, and the first movement component is arranged on the support; the second horizontal movement structure includes a first moving plate and a second movement component. There are two groups of the first moving plates, which are respectively connected to the first movement component, and both ends of the second movement component are arranged on the first moving plate. The first movement component of the first horizontal movement structure drives the second movement component installed on the first moving plate to move in the horizontal direction.

[0012] Further, the laser marking structure includes a second moving plate, a detection structure, a manual adjustment table, and a laser marking component. The detection structure is arranged on the side of the second moving plate, the manual adjustment table is arranged on the second moving plate, and the laser marking component is installed on the side of the manual adjustment table. The detection structure detects the position of the PCB board, which facilitates the first limiting structure, the second limiting structure, the lifting table, and the first movement component and the second movement component to adjust the marking position of the PCB board, thereby improving the printing position accuracy of the laser marking component. The manual adjustment table is used to manually adjust the position of the laser marking component to ensure that different types of PCB boards are at the most suitable height when lifted by the lifting table.

[0013] Further, the detection structure includes a connecting seat, an adjustment plate, and a detection head. The detection head is arranged at the end of the connecting seat through the adjustment plate. The detection structure is installed on the second moving plate through the connecting seat, and the adjustment plate is used to adjust the position and angle of the detection head, thereby improving the detection accuracy.

[0014] Furthermore, it also includes an exhaust ventilation structure, which can timely absorb and process the smoke and waste gas generated during the laser coding process, and release them after purification through a filter, thereby improving the working environment quality and ensuring the health of the operators.

[0015] As can be seen from the above technical solutions, the utility model has the following beneficial effects: 1) By setting a conveying structure, a workbench structure, and a movable laser structure, continuous laser coding work on PCB boards can be achieved. Its operation is simple, which not only greatly reduces the workload of workers, but also has a high working efficiency and is suitable for mass coding work of PCB boards; 2) By setting a lifting platform, a positioning structure, a first limiting structure, a second limiting structure, a first moving structure, a second moving structure, and a detection structure, the position of the PCB board can be automatically adjusted, greatly improving the accuracy of laser coding and thus improving the product quality; 3) By setting an exhaust ventilation structure, the smoke and waste gas generated during the laser coding process can be timely absorbed and processed, thereby improving the working environment quality and ensuring the health of the operators.
