Description

Technical Field

[0001] The utility model relates to the technical field of machine tool positioning cameras, and specifically relates to a vision positioning camera for circuit board drilling. Background Technique

[0002] The automatic drilling and target punching machine for circuit boards is a numerical control machine tool. When drilling, it is necessary to take a vision positioning of the drilling position. In the existing circuit board drilling device, since the drill bit is located directly above or below the drilling position, it is difficult for the camera to vertically photograph the drilling position. Therefore, multiple cameras at fixed positions are generally used to photograph the drilling position, thereby reducing the shooting blind area and improving the positioning accuracy. However, when the position height of the cameras at fixed positions is relatively high, the blind area is large, and when the position height is relatively low, it is not conducive to the loading and unloading of the circuit board. There is a need for a vision positioning camera for circuit board drilling that is convenient for positioning and shooting. Content of the Utility Model

The mobile camera modules 300 are used to photograph the drilling position.

[0028] Specifically, the lifting end of the main arm drives the lifting frame 200 to lift and lower, thereby driving the drill bit to move up and down to drill the circuit board below. When the lifting frame 200 moves up and down, it drives the fixing seats 270 to rotate, thereby driving the two mobile camera modules 300 to rotate accordingly, so that the two mobile camera modules 300 always aim at the drilling position directly below the drill bit when moving up and down with the lifting frame 200, realizing accurate photographing of the drilling position and reducing the shielding effect of the drill bit on the drilling position.
