Description

Technical Field

[0001] The utility model relates to the technical field of optical marking paper reviewing machines, in particular to a high-frequency anti-interference optical marking paper reviewing machine. Background Art

[0002] An optical marking machine is a machine that, if it is dark, part of the light is absorbed and the reflected light becomes weaker. Otherwise, the reflected light becomes stronger. The corresponding receiving tube transfers the light signals of different strengths into electrical signals, and then completes the recognition of the characters in the information card after A / D conversion, digital filtering and pattern recognition.

[0003] Optical mark marking machines use infrared technology for distance measurement and positioning. High-frequency electromagnetic signals can cause electromagnetic interference. Some electronic products or wireless devices will generate high-frequency electromagnetic signals. Electromagnetic interference can cause the optical mark marking machine to read inaccurate distance measurement data. Therefore, when using an optical mark marking machine in an environment with strong high-frequency interference, appropriate interference shielding measures need to be taken to ensure the accuracy and stability of the measurement.

[0004] Existing optical mark marking machines generally do not process high-frequency signals, which will cause the reading accuracy and speed of the optical mark marking machines to decrease. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model provides a high-frequency anti-interference optical marking paper reading machine.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a high-frequency anti-interference optical marking machine, including a frame, a paper feed control mechanism, a mechanical transmission mechanism, a photoelectric sensor, an identification mechanism and a high-frequency anti-interference module. The paper feed control mechanism is located on the upper side of the frame, the mechanical transmission mechanism is located on the lower side of the frame, the photoelectric sensor is located on the upper side of the frame, the identification mechanism is located in the middle of the frame, and the high-frequency anti-interference module is located at the upper end of the frame.

[0007] By adopting the above technical solution, a high-frequency anti-interference module is set at the upper end of the rack module to consume the energy of the interference magnetic field, thereby offsetting the high-frequency interference magnetic field, so that the cursor reader is protected from interference from high-frequency signals, and the optical mark reading machine has higher reading accuracy.

[0008] Optionally, the high-frequency anti-interference module includes a power supply component base plate, and a carrier plate 1 and a carrier plate 2 are respectively installed on the lower sides of both ends of the power supply component base plate, and the carrier plate 1 and the carrier plate 2 are detachably connected to the rack. The bottom end of the power supply component base plate is fixedly connected with a high-frequency anti-interference component, and the high-frequency anti-interference component includes an inner compartment cavity, an anti-interference copper plate, an anti-interference aluminum plate, reinforcing ribs and a reinforcing block. The inner compartment cavity is arranged at the bottom of the wireless terminal housing, the anti-interference copper plate is arranged on one side of the inner side wall of the inner compartment cavity, the anti-interference aluminum plate is arranged on the other side of the inner side wall of the inner compartment cavity, the reinforcing block is arranged inside the inner compartment cavity, and the reinforcing ribs are fixedly connected to the outer side wall of the reinforcing block.

[0009] By adopting the above technical solution, a high-frequency anti-interference component is used to process the high-frequency interference signal near the optical mark reader. The anti-interference copper plate and the anti-interference aluminum plate are resistance materials with good conductivity. The eddy current principle can be used for the high-frequency interference magnetic field, so that the high-frequency interference electromagnetic field generates eddy currents in the shielding metal, consuming the energy of the interference magnetic field, so that the eddy current magnetic field offsets the high-frequency interference magnetic field.

[0010] Optionally, the first bearing plate and the second bearing plate are both connected to the frame by bolts.

[0011] By adopting the above technical solution, the bolt connection is not only convenient for disassembly and installation, but also convenient for adjusting the height of the first bearing plate and the second bearing plate.

[0012] Optionally, insulating pads are installed at both ends of the power supply assembly base plate.

[0013] Optionally, a partition cavity is provided in the insulating pad.

[0014] By adopting the above technical solution, the insulating pad prevents the bottom plate of the power supply component from contacting other metals.

[0015] Optionally, the identification mechanism includes a photoelectric sensor and a DSP chip, and the photoelectric sensor is connected to the DSP chip.

[0016] By adopting the above technical solution, the DSP chip makes the information card recognition process simpler and the recognition result more accurate compared to the central control machine.

[0017] The utility model provides a high-frequency anti-interference optical mark reading machine, which consumes the energy of the interference magnetic field by arranging the high-frequency anti-interference module at the upper end of the frame module, thereby offsetting the high-frequency interference magnetic field, so that the cursor reader is free from the interference of the high-frequency signal, and the reading accuracy of the optical mark reading machine is higher, and the high-frequency anti-interference module is arranged on the upper end of the optical mark reading machine through the power supply component bottom plate, the first carrier plate and the second carrier plate, and the distance between the high-frequency anti-interference module and the optical mark reading machine can be adjusted by connecting the first carrier plate and the second carrier plate to the frame with bolts.
