The board detecting apparatus 10 includes a conveying mechanism 200, a detecting mechanism 300, and a board adjusting mechanism 100.

The conveying mechanism 200 is formed with a conveying plane 220 for conveying the board body 400 to be measured in the conveying direction x. The conveying mechanism 200 may include a plurality of conveying rollers 210 disposed at intervals along a conveying direction x, the plurality of conveying rollers 210 collectively form a conveying plane 220, the conveying rollers 210 may rotate to drive the plate body 400 to be detected on the conveying plane 220 to move along the conveying direction x, wherein the conveying rollers 210 may rotate around an axis direction thereof, and the conveying direction x may be defined as a direction in which the conveying rollers 210 are radial and parallel to the conveying plane 220. In other embodiments, the conveying mechanism 200 may also form the conveying plane 220 by other structures to convey the board body 400 to be tested along the conveying direction x, for example, the conveying plane 220 may be formed by conveying spheres, and the spheres are rotated to drive the board body 400 to be tested to move along the conveying direction x. The Board 400 to be tested may include a Printed Circuit Board (PCB), a Flexible Printed Circuit (FPC), and other Board devices that need to be optically detected by the Board detection apparatus 10.

The detection mechanism 300 is located downstream of the conveying mechanism 200 in the conveying direction x, and the detection mechanism 300 is used for receiving and detecting the board 400 to be detected. The conveying mechanism 200 may include an image capturing device for capturing an image of the board 400 to be tested, and a conveying device for conveying the board 400 to be tested to the detection position. The detection mechanism 300 is located downstream of the conveying mechanism 200 in the conveying direction x, and the plate body 400 to be detected is conveyed to the transfer plane of the conveying equipment of the detection mechanism 300 through the conveying mechanism 200, so that the plate body 400 to be detected is conveyed to the detection position continuously along the conveying direction x, wherein the detection position can be an area range on the conveying mechanism 200, and the image acquisition equipment can acquire images of the plate body 400 to be detected in the area range. Image acquisition equipment can be located the upside and/or the downside that await measuring plate body 400 deviates from conveying equipment, and image acquisition equipment and the plate body 400 interval that awaits measuring set up, and image acquisition equipment is used for gathering the image information of the plate body 400 that awaits measuring, calculates in order to compare, analysis and judgement through the embedded software of computer in succession through the processing, finally obtains the testing result of the plate body 400 that awaits measuring. However, if no other component is used to adjust the position of the board body 400 to be detected, during the process of conveying the board body 400 to be detected by the conveying mechanism 200, the board body 400 to be detected entering the detecting mechanism 300 may be skewed, which may cause difficulty in defining the area of the board body 400 to be detected where the acquired image of the board body 400 to be detected is located, so that the final detection result is inaccurate.

The board adjusting mechanism 100 is located between the conveying mechanism 200 and the detecting mechanism 300, the board adjusting mechanism 100 includes an adjusting member 110, and the adjusting member 110 is configured to move to a first position protruding from the conveying plane 220 in a stretching direction y perpendicular to the conveying plane 220, so as to adjust a position relationship of the board 400 to be detected on the conveying plane 220 in a process that the board 400 to be detected moves along the conveying direction x.

Through the above embodiment, the board adjusting mechanism 100 is disposed between the conveying mechanism 200 and the detecting mechanism 300, when the board 400 to be tested moves along the conveying direction x, the adjusting member 110 can move to the first position protruding from the conveying plane 220 in the stretching direction y perpendicular to the conveying plane 220, and when the conveying mechanism 200 continues to convey the board 400 to be tested along the conveying direction x, the board 400 to be tested is blocked by the adjusting member 110, so as to adjust the position relationship of the board 400 to be tested on the conveying plane 220. For example, the board body 400 to be detected is generally square, when the detecting mechanism 300 normally detects the board body 400 to be detected, the board body 400 to be detected should vertically enter the detecting mechanism 300, however, in the process of conveying the board body 400 to be detected by the conveying mechanism 200, the board body 400 to be detected entering the detecting mechanism 300 may be skewed and the like, as in the case of the board body 400 to be detected in fig. 1, at this time, the adjusting member 110 may move to the first position protruding from the conveying plane 220 to block the board body 400 to be detected from entering the detecting mechanism 300, and meanwhile, because the conveying mechanism 200 still performs the operation of conveying the board body 400 to be detected in the conveying direction x, the board body 400 to be detected can continuously collide with the adjusting member 110 slightly, so that one side line of the board body 400 to be detected abuts against the adjusting member 110, thereby completing the operation of adjusting the positional relationship of the board body 400 to be detected on the conveying plane 220, so that the detecting mechanism 300 can detect the adjusted board body 400 to be detected, and avoiding the inaccurate detection result.

After the adjustment of the board 400 to be detected is completed, in order to enable the board 400 to be detected to smoothly enter the detection mechanism 300, the adjusting element 110 needs to cancel the state of stopping the board 400 to be detected to move along the conveying direction x. Specifically, the adjusting member 110 can move from the first position to the second position not protruding from the conveying plane 220 in the telescopic direction y, so that the conveying mechanism 200 can convey the adjusted board 400 to be detected to the detecting mechanism 300. The second position is located at the lower side of the conveying plane 220, so that the conveying mechanism 200 can smoothly convey the board 400 to be detected to the detecting mechanism 300 after the adjusting member 110 completes the position adjusting operation on the board 400 to be detected, so as to perform the detecting operation on the board 400 to be detected by using the detecting mechanism 300.

The adapter member 123 and the telescopic member 122 may be integrally formed, and the surface area of the adapter member 123 is larger than that of the telescopic member 122, so that when the telescopic member 122 is connected with the adjusting member 110 through the adapter member 123, the stability of connection between the adjusting member 110 and the telescopic member 122 can be improved.

In one embodiment, there are two telescopic members 122, the two telescopic members 122 are spaced from each other and are respectively connected to the adaptor member 123, and the two telescopic members 122 move synchronously in the telescopic direction y.
