Description
Technical Field
The present invention relates to a sensing device and a sensing module thereof, and more particularly, to a sensing device and an optical sensing module thereof for optical recognition.
Background
With the advancement of science and technology, the existing reading books often combine text, text and sound to make the reader interested in reading the books. For example: CD or MP3 player with sound files stored. However, this method makes it necessary for the user to search the related sound file when reading the book, which is inconvenient for reading. Therefore, an optical reading pen is produced, which uses an optical identification (optical identification) technology to read the optical identification code when the optical reading pen points to the characters or images on the book, and then generates a sound through a sound-generating device to improve the reading and learning effect.
Generally, an optical point-reading pen includes a light source and an optical sensor, wherein the light source provides light to a page of a book, and the optical sensor can sense an optical identification code on the page. Some optical point-and-read pens are also provided with additional functional components, such as a pen core and a corresponding pen holder, so that the optical point-and-read pen can be used for recording or tracking the moving track or position of the point-and-read pen to write or touch in addition to point-and-read. However, in the design of the optical touch and talk pen at present, the pen core and the corresponding pen holder are installed on the same base as the existing light source and optical sensor, so that the mold opening difficulty of the base is high, and when any part of the base is changed, the mold opening of the whole base needs to be performed again, so that the rework is inconvenient. In addition, since the components of the optical point-reading pen are installed on the same base as described above, when the optical point-reading pen does not need to provide a writing function through the pen core, even if the pen core and the corresponding pen holder are removed, the opening for installing the pen holder and the pen core on the base still occupies space, so that the volume of the optical point-reading pen cannot be correspondingly reduced.

Referring to fig. 1, 2 and 4, in the present embodiment, the first base 112 of the optical sensing module 110 and the second base 122 of the additional function module 120 are not integrally formed, and are designed to be assembled with and disassembled from each other. Specifically, an outer side 112c of the first base 112 has a first fixing structure 112d, and the second base 122 has a second fixing structure 122 b. The first base 112 and the second base 122 are fixed to each other by a first fixing structure 112d and a second fixing structure 122 b.
With the above configuration, the functional component 124 and the existing light source 114 and optical sensor 116 are respectively installed on different bases (the first base 112 and the second base 122) so that the structure of each base is simple to reduce the difficulty of opening the mold, and when the design of the first base 112 or the second base 122 is changed, the mold opening of the first base 112 or the second base 122 is only required to be performed again without performing rework on all the bases, so that the rework is convenient.

In other embodiments, the first fixing structure 112d and the second fixing structure 122b can be fixed to each other by other suitable structures, such as hooks and tenons, which is not limited in the present invention.
In the above embodiment, the optical sensing module 110 and the additional function module 120 may be further accommodated by a housing (not shown) to make the sensing device 100 have a better appearance and a better grip feeling, which is not limited in the present invention. Further, the sensing device 100 may not be provided with the second base 122 and the functional component 124, and the first fixing structure 112d of the first base 112 may be configured to be fixed to a corresponding structure in the housing, so that the first base 112 is accommodated in the housing and the housing covers the outer side 112c of the first base 112, wherein the housing is clamped by, for example, a clamping slot S of the first fixing structure 112d, but the combination manner of the first base 112 and the housing is not limited in the present invention.
Referring to fig. 3, in the present embodiment, the light source 114 is, for example, a light emitting diode device and is adapted to provide light L along a light emitting direction a. The light emitting direction a of the light source 114 is not parallel to the surface 52 of the object 50, so that the light L is directly transmitted to the surface 52 of the object 50. However, the light emitting direction of the light source is not limited in the present invention, and the following description is given by way of example with reference to the accompanying drawings.
FIG. 5 shows an optical recognition performed by the sensing device according to another embodiment of the present invention. In the sensing device 200 of the invention, the configuration and operation of the optical sensing module 210, the first base 212, the first opening 212a, the second opening 212b, the optical sensor 216, the additional function module 220, the second base (not shown), the functional element 224, and the tube 226 are similar to the configuration and operation of the optical sensing module 110, the first base 112, the first opening 112a, the second opening 112b, the optical sensor 116, the additional function module 120, the second base 122, the functional element 124, and the tube 126 of fig. 1 to 4, and are not described herein again. The sensing device 200 differs from the sensing device 100 in that the light emitting direction a' of the light source 214 is parallel to the surface 52 of the object 50, so that the light source 214 emits light in a lateral manner.
By designing the light source 214 to emit light laterally as described above, the intensity of the light L impinging on the surface 52 of the object 50 can be reduced moderately. Accordingly, in the case where the object 50 is a liquid crystal display panel, the structure under the surface 52 of the liquid crystal display panel is not unexpectedly sensed by the optical sensor 216 due to the irradiation of the light L, so as to ensure that the optical sensor 216 can correctly sense the identification code on the surface 52. It should be noted that, if the object 50 is a liquid crystal display panel, for example, a transparent film having the identification code is attached to the surface 52 for the optical recognition of the sensing device 200, and the functional element 224 has no writing function and is only supported between the optical sensing module 210 and the surface 52. In addition, under the condition that the reflectivity of the transparent film is high, the light source 214 is designed to emit light laterally to reduce the light intensity of the light L irradiating the surface 52 of the object 50, so as to prevent the light L' reflected by the transparent film from being too strong to affect the normal operation of the optical sensor 216.
In the present embodiment, the structure of the first base 212 at the first opening 212a extends toward the surface 52 of the object 50 as shown in fig. 5, so that the light source 214 in the first opening 212a can be relatively adjacent to the surface 52 of the object 50, and the first base 212 has a light outlet 212b at the first opening 212a, so that the light L emitted by the light source 214 can be smoothly transmitted to the surface 52 through the light outlet 212 d. In other embodiments, the structure of the first base 212 at the first opening 212a may be designed with other suitable shapes and sizes, which is not limited in the invention.
In summary, in the sensing device of the present invention, the light source and the optical sensor are mounted on the first base, the functional component is mounted on the second base, and the first base and the second base can be fixed or detached by the first fixing structure and the second fixing structure. Therefore, the functional component and the existing light source and the optical sensor are respectively arranged on different bases, so that the structure of each base is simple to reduce the die opening difficulty, and when the design of the first base or the second base is changed, the die opening of the first base or the second base is only needed to be carried out again without reworking all the bases, so that the reworking is convenient. In addition, when the sensing device does not need to provide corresponding functions by additional functional components, the second base and the functional components arranged on the second base can be directly detached from the first base, so that the volume of the sensing device is effectively reduced, and the flexibility of the optical sensing module and the additional functional components in matching use is improved. Further, under the condition that the second base and the functional component are not needed to be installed, the first fixing structure of the first base can be fixed with the shell of the sensing device instead, so that the universality of the first fixing structure of the first base is improved. In addition, the light source can be designed to emit light laterally, so that the light intensity of the optical sensing module is reduced moderately, and the influence on the normal operation of the optical sensor caused by the overlarge light intensity of the light source is avoided.
Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited to the embodiments, and various changes and modifications can be made by one skilled in the art without departing from the spirit and scope of the invention.
