Scanner swing blade driving control device

Abstract

The invention discloses a scanner swing blade driving control device. The device comprises a swing blade mechanism, wherein the swing blade mechanism comprises a main plate, a flexible swing blade isarranged on one side of an upper portion of the main plate, a magnet is arranged on the other side of the upper portion of the main board, a flexible circuit board is arranged on the flexible swing blade, an FPC coil is printed on a side face of the flexible circuit board close to the magnet, a reflector is arranged on the side face of the flexible circuit board away from the magnet, the swing blade mechanism is connected with a driving control module through signals, and a driving circuit is connected between the driving control module and the swing blade mechanism. During use, deformation ofthe FPC swing blade during powerful driving can be eliminated, power consumption is lower, more energy is saved, line damage in the FPC coil swing blade can be reduced, the service life is longer, temperature rising of the flexible swing blade caused by a large current is avoided, the service life of the flexible swing blade is prolonged, and the device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of scanners, in particular to a control device for driving the swing blades of the scanner. Background technique [0002] In a laser scanner or a marking device, it is necessary to turn the point laser into a scanning line, that is, the point light source is converted into a line light source. When the laser is converted into a point light source, it must be stable and reliable. For laser scanners or marking devices The drive control of the swing leaf device generally adopts the high current and strong drive mode at present to ensure the specified swing swing. [0003] However, there are following disadvantages in driving and controlling the swing blade device through the above method: [0004] 1. It adopts powerful driving mode, which consumes a lot of current and does not save energy; [0005] 2. The continuous high current on the FPC coil will cause the temperature of the FPC swing blade to rise, result...

Problems solved by technology

[0004] 1. It adopts powerful driving mode, which consumes a lot of current and does not save energy;

[0005] 2. The continuous high current on the FPC coil will cause the temperature of the FPC swing blade to rise, resulting in the continuous aging of the characteristics of the FPC swing blade itself and shortening the service life
