Description

Technical Field

[0001] The utility model belongs to the technical field of printed circuit board manufacturing equipment, and particularly relates to a printed board vision recognition device with a transparent roller. Background Technique

[0002] With the continuous development and popularization of electronic products, the printed circuit board (PCB), as a core component of electronic devices, has an increasing demand. In the manufacturing process of PCB, the roller is an important horizontal conveying component. In the manufacturing scenarios of high-end PCBs, such as the carrier board production line and the browning process of conventional boards, the PCB cannot be positioned by contact and needs to rely on machine vision for accurate grasping.

[0003] Since the PCB is supported by rollers on the horizontal production line, and the rollers are made of non-transparent materials such as the axle center and the wheel disc, traditional machine vision is extremely prone to misjudging the PCB edge line when identifying the PCB on the roller, which reduces the reliability and accuracy of the vision system and seriously affects the effect of accurately grasping the PCB.

[0004] Therefore, in view of the above current situation, there is an urgent need to develop a printed board vision recognition device with a transparent roller to overcome the deficiencies in current practical applications. Summary of the Invention

[0005] The purpose of the embodiment of the utility model is to provide a printed board vision recognition device with a transparent roller, aiming to solve the problems proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A printed board vision recognition device with a transparent roller includes two symmetrical roller fixing seats. On the side where the two roller fixing seats are close to each other, a plurality of uniformly distributed roller bearings are fixedly arranged. The roller bearings on the two roller fixing seats correspond one by one, and the inner wall of each roller bearing is fixedly connected with a roller shaft head. A transparent roller rod is fixedly connected between the two roller shaft heads. On one side of the transparent roller rod, a camera and a light source on the same side are fixedly arranged, and on the other side of the transparent roller rod, a backlight source is fixedly arranged.

[0008] A further technical solution is that the transparent roller rod is made of quartz glass, borosilicate glass, glass-ceramics, plexiglass or composite transparent material, and both ends of the transparent roller rod are flat.

[0009] A further technical solution is that the transparent roller rod is hollow or solid.

[0010] The utility model does not interfere with the shooting effect of the camera through the transparent roller rod body, and shoots the silhouette effect of the PCB board through the cooperation of the transparent roller rod body, the same-side light source and the back-side light source, obtaining a PCB board picture with clear boundaries, and having the effects of easy implementation, low cost and no interference from the roller side line.

[0011] In order to more clearly illustrate the structural features and functions of the present utility model, the present utility model will be described in detail below with reference to the drawings and specific embodiments. Description of the Drawings

[0015] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0017] As Figure 1 and Figure 2 shown, the embodiment of the present utility model provides a printed circuit board vision recognition device with a transparent roller, including two symmetric roller fixing seats 4. On the mutually approaching surfaces of the two roller fixing seats 4, a plurality of evenly distributed roller bearings 3 are fixedly arranged. The roller bearings 3 on the two roller fixing seats 4 correspond one by one, and the inner wall of each roller bearing 3 is fixedly connected with a roller shaft head 2. A transparent roller rod body 1 is fixedly connected between the two roller shaft heads 2. A camera 5 and a same-side light source 6 are fixedly arranged on one side of the transparent roller rod body 1, and a back-side light source 7 is fixedly arranged on the other side of the transparent roller rod body 1.

[0018] Preferably, the two roller shaft heads 2 are fixedly formed into a transparent roller assembly by gluing with the transparent roller rod body 1.

[0019] Furthermore, the transparent roller rod body 1 is made of quartz glass, borosilicate glass, glass-ceramics, plexiglass or composite transparent materials, and both ends of the transparent roller rod body 1 are flat. The roller shaft head 2 is made of metal or non-metal materials.

[0020] Furthermore, as Figure 1 and Figure 2 shown, the transparent roller rod body 1 is hollow or solid. When the solid transparent roller rod body 1 is adopted, the shaft head end of the roller shaft head 2 is sleeved on the outer wall of one end of the transparent roller rod body 1. When the hollow transparent roller rod body 1 is adopted, the shaft head end of the roller shaft head 2 is fixedly connected to the inner wall of the transparent roller rod body 1.

[0021] In the embodiment of the present utility model, the shooting effect of the camera 5 is not interfered by the transparent roller rod body 1. The silhouette effect of the PCB board is captured by the cooperation of the transparent roller rod body 1, the same-side light source 6 and the back-side light source 7, and a PCB board picture with clear boundaries is obtained, which has the effects of easy implementation, low cost and no interference from the roller side lines.

[0022] The working principle of the present utility model is as follows: The PCB board is conveyed on the transparent roller rod body 1. By starting and switching the same-side light source 6 and the back-side light source 7, the camera 5 can directly capture the silhouette effect of the PCB board, and a PCB board picture with clear boundaries can be obtained. Then, the PCB board is accurately grabbed by relevant equipment.

[0023] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
