The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

[0040] In the production of cameras, the industrial cameras in the related art generally do not include a spectral sensor, so that in the use process, in order to ensure the imaging quality, a complex adjustment process is required, which affects the convenience of use of the camera and cannot meet the needs of users; however, in order to integrate the spectral sensor into the camera, a large change needs to be made to the structure of the industrial camera (that is, the compatibility of the structure of the current industrial camera with the spectral sensor is poor), and the volume of the current industrial camera integrated with the spectral sensor is generally large.

[0041] Based on this, referring to the accompanying drawings Figure 1 and Figure 3 The first aspect of the application discloses a front cover assembly, which comprises a front cover body 11, an image sensor 12 and an annular mounting table 1111, a light transmission channel 1121 with a lens port is formed on the front cover body 11, the annular mounting table 1111 is formed on the inner wall of the light transmission channel 1121, the annular mounting table 1111 is located in the light transmission channel 1121 and is used for mounting a light transmission sheet 15, the lens port is located at the front end of the front cover body 11, a light transmission groove 1112 is formed on the surface of the annular mounting table 1111 facing the lens port, the front cover assembly 10 further comprises a spectral sensor 13, the photosensitive surface of the image sensor 12 is opposite to the lens port through the central cavity of the annular mounting table 1111, and the photosensitive surface of the spectral sensor 13 is opposite to the lens port through the light transmission groove 1112.

[0042] The image sensor 12 in the embodiment is used as a photosensitive element to receive light reflected or projected by the surface of an object, so as to realize imaging of the object to be photographed.

[0043] The front cover assembly 10 in the embodiment is provided with the spectral sensor 13, which can be used to collect spectral information of an environmental light source in real time, so that when the light source changes, the industrial camera can automatically acquire the current spectral information of the environmental light source, and perform color processing on an original image based on a color correction matrix corresponding to the spectral information, to obtain a target image with high color restoration, without the need to perform color correction and white balance adjustment on the industrial camera according to the change of the light source, thereby simplifying the adjustment process of the industrial camera. It can be seen that, through the arrangement of the spectral sensor 13, the adjustment process of the industrial camera can be improved, and the imaging quality can be more easily ensured.

[0044] The spectral sensor 13 in the embodiment is more compatible with the industrial camera in the related art, and in actual arrangement, only a light transmission groove 1112 is arranged on the annular mounting table 1111 for mounting the light transmission sheet 15 in the existing industrial camera, the light receiving surface of the spectral sensor 13 is arranged at a position opposite to the light transmission groove 1112, the light receiving surface of the spectral sensor 13 is opposite to the lens port, and light entering the lens port can be received by the light receiving surface of the spectral sensor 13, so that the structure of the industrial camera is less affected.

[0045] The light receiving surface of the image sensor 12 in the embodiment is opposite to the lens port through the central cavity of the annular mounting table 1111, and the spectral sensor 13 is opposite to the lens port through the light transmission groove 1112, and it can be seen that the arrangement of the spectral sensor 13 does not block or reduce the light receiving area of the image sensor 12, and the compatibility with the industrial camera in the related art can be well realized.

[0046] The specific arrangement mode and shape of the light transmission groove 1112 are not limited in the embodiment, and in actual arrangement, the light transmission groove 1112 can be arranged as a structure penetrating the annular mounting table 1111, or as a non-penetrating structure; the cross-sectional shape of the light transmission groove 1112 can be arranged as a direction or a special shape.

[0047] The light transmission groove 1112 is arranged on the existing structure (the annular mounting table 1111 for mounting the light transmission sheet) of the front cover assembly, the overall structure is more compact, and the volume of the industrial camera can be reduced.

[0048] As one of the embodiments of the utility model, referring to the accompanying drawings Figure 4 、 5 The light transmission groove 1112 comprises a mounting surface opposite to the lens port, and the spectral sensor 13 is arranged on the mounting surface.

[0049] The front cover assembly comprises a circuit board 14, the circuit board 14 is arranged on the rear side of the annular mounting table 1111 and is fixedly connected with the front cover body 11, the image sensor 12 is fixed on the circuit board 14, a threading hole 1113 is formed in the inner wall of the light transmission groove 1112, one end of the threading hole 1113 is opposite to the circuit board 14, the spectral sensor 13 further comprises an electric connecting piece 131, the electric connecting piece 131 penetrates the threading hole 1113 and electrically connects the spectral sensor 13 and the circuit board 14.

[0050] The circuit board 14 in the embodiment is used as a mounting base of the image sensor 12, which is generally mounted at the end of the front cover assembly 10 opposite to the lens port. In actual arrangement, the mounting surface of the circuit board 14 faces the lens port, and the image sensor 12 is directly arranged on the circuit board 14 and electrically connected with the electrical elements on the circuit board 14.

[0051] The light-transmitting groove 1112 in the embodiment is arranged as a non-through structure, so that the bottom wall of the light-transmitting groove 1112 faces the lens port, and the spectral sensor 13 can be mounted on the bottom surface of the light-transmitting groove 1112. Since the spectral sensor 13 needs to be electrically connected with the circuit board 14 in use, a threading hole 1113 is arranged on the side wall of the light-transmitting groove 1112, which is used to accommodate an electrical connecting element 131 for electrical connection between the spectral sensor 13 and the circuit board 14. As shown in FIG. 6. Figure 4 、 5 、6.

[0052] The spectral sensor 13 and the image sensor 12 in the embodiment are arranged at different mounting positions, so that the circuit board 14 can meet the mounting requirement of a larger-area image sensor 12, and thus the structure of the front cover assembly 10 in the embodiment can be suitable for the mounting requirement of an image sensor 12 with a large target surface.

[0053] The light-receiving surface of the spectral sensor 13 and the light-receiving surface of the image sensor 12 in the embodiment are arranged at intervals along the axial direction of the front cover body 11, but the projections in the axial direction do not coincide (wherein the projection of the light-receiving surface of the image sensor 12 in the axial direction falls within the central cavity of the annular mounting table 1111, and the projection of the light-receiving surface of the spectral sensor 13 is outside the projection area of the light-receiving surface of the image sensor 12), which does not affect the normal light-receiving requirements of the two.

[0054] In the case that the spectral sensor 13 is not arranged on the circuit board 14, in order to make the spectral sensor 13 more easily electrically connected with the circuit board 14 (the electrical connection port is generally arranged on the surface of the circuit board 14 away from the lens port) in the limited space, the circuit board 14 in one of the embodiments of the utility model is formed with an avoiding opening 141 opposite to the threading hole 1113, and one end of the electrical connecting element 131 passes through the avoiding opening 141 and is electrically connected to the back surface of the circuit board 14.

[0061] It should be noted that, since the spectral sensor 13 in the embodiment needs to occupy the mounting space of the circuit board 14 towards the lens port when mounted on the circuit board 14, and the image sensor 12 is an essential component of the camera, the mounting space thereof also needs to be ensured, and the arrangement of the spectral sensor 13 on the circuit board 14 will inevitably cause the reduction of the mounting space of the image sensor 12 (because both of them need to be mounted at the position towards the lens port), therefore, the mounting mode of the spectral sensor 13 in the embodiment is generally suitable for being used in combination with the image sensor 12 with a small target surface (small light-sensitive area), so that the normal use of the image sensor 12 can be ensured while the assembly efficiency of the whole machine is improved.
