The connecting wire or plug-in connection is prone to poor contact or disconnection after long-term use.

[0052] In a preferred embodiment, the integrated OID pen scanning device is as follows: Figure 2 As shown, the light guide device 4 includes:

[0053] A lens barrel portion 40 bent in an L-shape;

[0054] A first lens, which is preferably a concave lens 8, is disposed at one end of the lens barrel 40 and is used to emit light;

[0056] a reflector 7, the reflector 7 being arranged at a bending position of the lens barrel 40 and being used for reflecting light;

[0057] The end 41 of the lens barrel 40 provided with a first lens is mounted on the OID code scanning camera 2; the infrared light emitted by the infrared fill light 3 is reflected by the object printed with the OID code and converged to the reflector 7 through the second lens (convex lens 6) arranged at the other end of the lens barrel, and then the reflector 7 reflects the infrared light to the first lens (concave lens 8) arranged at one end of the lens barrel, and then the infrared light is diverged and projected to the OID scanning camera 2 through the second lens (concave lens 8).

[0058] The present application has the following effects: the OID scanning camera 2 and the infrared fill light 3 can be integrated on the mainboard 1 of the optical point-to-point reading device, effectively reducing the module cost and the production cost of connectors or other electrical connection components.

[0059] Specifically, Figure 2As shown, in the integrated OID pen tip scanning device of the present invention, the light guide device 4 preferably includes:

[0060] A lens barrel portion 40 bent in an L-shape;

[0061] A concave lens 8, wherein the concave lens 8 is disposed at one end of the lens barrel 40 and is used for emitting light;

[0062] A convex lens 6, which is disposed at the other end of the lens barrel 40 and is used to converge light;

[0063] A reflector 7, wherein the reflector 7 is arranged at a bending position of the lens barrel and is used for reflecting light;

[0064] In the embodiment of the present application, one end of the lens barrel portion is provided with a concave lens 8 which is mounted on the OID code scanning camera 2; the infrared light emitted by the infrared fill light 3 is reflected by the object 5 printed with the OID code, and converges to the reflector 7 through the convex lens 6 arranged at one end of the lens barrel portion, and then the reflector 7 reflects the infrared light to the concave lens 8 arranged at the other end of the lens barrel portion, and then the infrared light is diverged and projected to the OID scanning camera through the concave lens 8.

[0065] As can be seen from the above, in the embodiment of the present invention, the convex lens 6, the reflector 7, and the concave lens 8 are sequentially arranged on the light guide device 4, and the infrared light emitted by the infrared fill light 3 is converged, reflected, and emitted to the OID scanning camera. The OID scanning camera 2 and the infrared fill light 3 can be integrated on one side of the main board 1 at the same time without being arranged separately, thereby effectively saving installation space. In this way, the OID scanning camera and the main board can be arranged in an integrated manner, which facilitates the integration of the OID code scanning camera on the main board of the reading pen or stylus pen, reducing the module cost and the production cost of connectors or other electrical connection components.

[0066] In a further embodiment, the integrated OID pen scanning device is as follows: Figure 3 As shown, the lens barrel portion 40;

[0067] A first lens barrel portion 43, wherein the first lens barrel portion 43 is sleeved on the OID code scanning camera 2;

[0068] A second lens barrel portion 44 is connected to the first lens barrel portion 43 and is vertically disposed to the first lens barrel portion 43;

[0069] An inclined portion 45 connected to a side wall between the first lens barrel portion 43 and the second lens barrel portion 44;

In this embodiment, the lens barrel portion 40 is arranged vertically with the first lens barrel portion 43 and the second lens barrel portion 44. Such a lens barrel arrangement occupies a small space and is more convenient for converging and reflecting the infrared rays emitted by the infrared fill light 3 back to the OID code scanning camera 2 through the corresponding lens, and is also convenient for processing.

[0071] Furthermore, the integrated OID pen scanning device, such as Figure 3 As shown, the second lens barrel portion 44 is arranged in parallel with the main board 1, which is beneficial to saving space. The infrared fill light 3 is arranged in parallel with the second lens barrel portion 44. In addition to saving installation space, it is more beneficial for the light guide device 4 to converge the infrared rays emitted by the infrared fill light 3 through the corresponding lens and reflect them back to the OID code scanning camera 2, and the processing is also convenient.

[0072] In a further embodiment, the integrated OID pen scanning device is as follows: Figure 3 As shown, the OID code scanning camera 2 is vertically fixed on the main board 1, and the main body of the infrared fill light 3 is arranged parallel to the main board 1, which can effectively save installation space.

[0073] In a further embodiment, the OID code scanning camera 2 described in the present application can preferably adopt a photosensitive coupling element or a complementary metal oxide semiconductor image sensor, which has better light sensing; the infrared fill light 3 can adopt a light emitting diode or a laser diode that emits infrared rays, which has a long service life.

[0074] Furthermore, the integrated OID pen scanning device, such as Figure 3 As shown, the OID code scanning camera 2, the light guide device 4 and the infrared fill light 3 are integrated on the main board 1. Compared with the existing separate settings, the OID code scanning camera 2, the light guide device 4 and the infrared fill light 3 are integrated on the main board 1 to make the overall structure more compact.

[0075] Based on the above embodiments, the present application also provides a light guiding method based on the integrated OID pen tip scanning device described in the above embodiments, referring to Figure 2 As shown, the light guiding method comprises the following steps:

[0076] The infrared fill light 3 generates fill light infrared rays;

[0077] The light guide device 4 projects the light cast by the infrared fill light 3 to the OID code scanning camera 2 by refraction and / or reflection;

[0078] The OID code scanning camera 2 obtains the OID code information by collecting the projected infrared rays.

[0079] Specifically, Figure 2 As shown, the infrared light emitted by the infrared fill light 3 is reflected by the object 5 printed with the OID code, and the reflected infrared light is converged to the reflector 7 through the convex lens 6 arranged at one end of the lens barrel 40, and then the infrared light is reflected by the reflector 7 to the concave lens 8 arranged at the other end of the lens barrel, and then the infrared light is diverged and projected to the OID scanning camera 2 through the concave lens 8. In this way, the OID code scanning camera 2 and the infrared fill light 3 are integrally mounted on the main board 1, and the fill light infrared light of the infrared fill light 3 can also be guided to the OID code scanning camera 2 through the light guide device.

[0080] As can be seen from the above, in the embodiment of the present invention, the convex lens 6, the reflector 7, and the concave lens 8 are sequentially arranged on the light guide device 4, and the infrared light emitted by the infrared fill light 3 is converged, reflected, and emitted to the OID scanning camera. The OID scanning camera 2 and the infrared fill light 3 can be integrated on one side of the main board 1 at the same time without being arranged separately, thereby effectively saving installation space. In this way, the OID scanning camera and the main board can be arranged in an integrated manner, which facilitates the integration of the OID code scanning camera on the main board of the reading pen or stylus pen, reducing the module cost and the production cost of connectors or other electrical connection components.

[0081] This application uses the refraction and reflection of light to integrate the OID code scanning camera and the infrared fill light on the main board of the optical point reading device. The infrared light reflected from the printed matter with the OID code is projected onto the OID code scanning camera by the light guide device, thus realizing the further integration of the optical point reading device. Compared with the existing OID code scanning and recognition, the OID code scanning camera and the infrared fill light are separated into different modules, and then connected to the main board of the optical point reading device through connectors or other electrical connection components, which increases the module cost and the production cost of connectors or other electrical connection components.

[0082] Based on the above embodiments, the present application also provides a point reading pen. The point reading pen of this embodiment includes: a point reading pen body, a point reading pen tip arranged at the front end of the point reading pen body, and the integrated OID pen tip scanning device described in any of the above items; the integrated OID pen tip scanning device described in this embodiment is installed on the point reading pen tip.

[0083] The present invention provides an integrated OID pen tip scanning device, a light guide method and a point reading pen, which integrate an OID code scanning camera 2 and an infrared fill light 3 on the main board 1 of the optical point reading device, and use reflection or refraction and other phenomena to project the hidden information code on the printed matter to the OID code scanning camera 2 attached to the main board 1 of the optical point reading device. The application principle is that the infrared fill light 3 projects infrared rays to the surface of the printed matter, and the OID code printed on the surface of the printed matter will reflect the infrared rays. The reflected infrared rays are projected onto the OID code scanning camera 2 via the light guide module, and the OID code scanning camera 2 can obtain the hidden information code in the printed matter, that is, the OID code. By implementing the present invention, the OID scanning camera and the infrared fill light 3 can be integrated into the main board 1 of the optical point reading device and directly connected to the main board 1, which effectively reduces the module cost and the production cost of connectors or other electrical connection components, and does not cause the problem of poor contact of the connecting wire or the plug-in or disconnection caused by long-term use, which can effectively extend the service life of the point reading pen of the integrated OID pen tip scanning device and save product installation space.

[0084] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made based on the above description. For example, the lens and reflective mirror combination of the light guide device in this embodiment can be changed to other lens and reflective mirror combinations, while keeping the other parts unchanged. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
