Description

Punching machine with pressing function

This creation department is related to the hole inspection device, and particularly refers to a hole inspection machine with a pressing function.

The hole inspection device of the circuit board is mainly to verify whether the drilling hole on the circuit board is in the correct position and whether the hole diameter is correct.

The Republic of China M325489 patent discloses a hole inspection device for LED light source, which focuses on the use of LED light source, thereby solving the conventional technology using ordinary lamps or high-frequency lamps, but often because the source has spectral flicker, it is easy to cause CCD in Accepting uncoordinated problems, causing errors in accuracy and the like.

At present, the hole inspection machine, including the above-mentioned hole inspection machine, mostly performs image capturing and inspection on the circuit board. However, if the circuit board to be inspected is not flat, for example, the position is raised (protruded) or concave. Under the CCD, the CCD will not be able to accurately capture the image due to the incorrect focal length, which will affect the test results. Therefore, for the problem that the board may be uneven, there must be a corresponding processing mechanism.

The main purpose of the present invention is to provide a punching machine having a pressing function, which can be pressed while inspecting the board to be inspected, thereby ensuring the flatness of the board to be inspected, thereby ensuring good inspection results.

The combination of the rail and the sliding sleeve is a conventional structure. In the present embodiment, it is only used as an example. The replacement of other devices, such as the hydraulic cylinder, the ball screw, the linear sliding rail, etc., is feasible. Replacement method.

The scanner 21 is elongated and is driven by a scan driving device 22 to be reciprocally movable along a scanning track 24. The scanning driving device 22 is exemplified by a linear sliding rail. The scanning track 24 has two sliding rails respectively located on opposite sides of the outer surface of the first transparent plate 13 of the fixed platform 12, and the two ends of the scanner 21 are movably disposed on the scanning rail 24, and are located at The fixed platform 12 is. The scanner 21 is a linear scanner that scans the area of the first transparent plate 13 through which it passes. In addition, the scan driving device 22 maintains a fixed relative relationship with the fixed platform 12, and can be fixed to the machine table together with the fixed platform 12 during implementation, or the scanning driving device 22 can be fixed to the fixed platform. On the 12th, since this kind of fixing method is a conventional one, it is not shown in the figure.

The light source 31 is elongated and is driven by a light source driving device 32 to be reciprocally movable along a light source rail 34. The light source driving device 32 is exemplified by a linear sliding rail. The light source track 34 has two slide rails respectively located on opposite sides of the outer end surface of the second transparent plate 17 of the movable platform 16. The two ends of the light source 31 are movably disposed on the light source track 34, and are located on the movable platform 16 . The light source 31 projects light having a predetermined width and a strip shape on the second transparent plate 17, and can irradiate the region of the second transparent plate 17 through which it passes. In addition, the light source driving device 32 is co-operating with the moving platform 16 and maintains a relatively fixed relationship with each other. Here, the light source driving device 32 can be fixed to the moving platform 16 during implementation, thereby maintaining a fixed spatial relationship. And can be moved with the moving platform 16. The light source 31 is driven in synchronization with the scanner 21, whereby the light source 31 can also move while the scanner 21 moves, so that the scanning can be continued during scanning. The device 21 provides a light source 31 for scanning.
