[0050] Now combined Figures 1 to 4 , various embodiments provided by the present invention are described. It should be understood that the following are merely illustrative embodiments of the present invention and do not constitute any particular limitation to the present invention.

[0051] The embodiment of the present invention provides a camera for a roller brush. Figure 1 This is one of the structural schematic diagrams of the shooting device of the roller brush provided by the present invention, see Figure 1 The shooting device of the roller brush comprises: a rotating shaft 10, a power member 20, a rotating wedge block 30 and a shooting member 40. Through the cooperation of the above components, the image of the roller brush A can be shot.

[0052] Specifically, the roller brush A is usually cylindrical, and in the photographing device, the rotating shaft 10 is used to mount the roller brush A. In use, by mounting the roller brush A on the rotating shaft 10, the roller brush A can be driven to rotate by the rotating shaft 10, so that images of the roller brush A at different angles can be captured by the fixed photographing member 40, avoiding the inconvenience caused by manually placing the roller brush A or frequently moving the photographing member 40.

[0053] Moreover, the output shaft of the power member 20 is connected to the rotating shaft 10, and is used to drive the rotating shaft 10 to rotate. Through the power member 20, the rotating shaft 10 and the roller brush A can rotate automatically, thereby saving manpower. Moreover, the power member 20 can drive the roller brush A to rotate a preset angle at one time. Each time the roller brush A stops rotating, the shooting member 40 is used to shoot once until the entire side of the roller brush A is shot. The shot pictures can be spliced ​​into a complete side picture of the roller brush A. Among them, the side of the roller brush A refers to the arc surface.

[0054] The rotating wedge 30 in the shooting device is arranged at the end of the rotating shaft 10 and is detachable in the axial direction. When in use, after the roller brush A is installed, the rotating wedge 30 is pushed axially to stop the roller brush A and prevent the roller brush A from detaching from the end of the rotating shaft 10, thereby facilitating the installation and removal of the roller brush A.

[0055] The above-mentioned shooting member 40 is arranged on the side of the rotating shaft 10, and is used to shoot the image of the roller brush A. Specifically, after each shooting, the roller brush A rotates a preset angle to take the next shot, until the shooting of the entire side of the roller brush A is completed, and the pictures taken can be spliced ​​into a complete side picture of the roller brush A.

[0056] The shooting device of the roller brush provided in the embodiment of the present invention can be used to install the roller brush A by setting the rotating shaft 10. The roller brush A can be locked by setting the rotating wedge 30. The power member 20 can provide power for the rotating shaft 10, thereby driving the roller brush A to rotate by a preset angle. The shooting device is also provided with a shooting member 40 for shooting. Each time the roller brush A rotates, the shooting member 40 can shoot an image of the roller brush A. Thus, the image of the roller brush A can be shot by the above-mentioned shooting device, so as to observe the self-cleaning effect of the roller brush A, etc.

[0057] Furthermore, a corresponding cleanliness test standard environment can be developed so as to extract the cleanliness of the roller brush before and after self-cleaning based on the above-mentioned images, and then judge the degree of dirtiness or self-cleaning effect.

[0058] Figure 2 This is the second structural schematic diagram of the shooting device of the roller brush provided by the present invention, see Figure 2 In one embodiment of the present invention, the camera device for the roller brush further includes: a dark box 50, which surrounds the outer side of the rotating shaft 10, the power member 20 and the rotating wedge 30. The dark box 50 is a light-shielding structure formed by a plurality of plates, and is used to shield the outer side of the roller brush A to prevent changes in external light from affecting the shooting effect. Moreover, the dark box 50 has an opening 51, and the camera member 40 is arranged outside the opening 51, so that the camera member 40 can capture the image of the roller brush A through the opening 51.

[0059] Correspondingly, the shooting device of the roller brush also includes a fill light 52, which is arranged on the inner wall of the dark box 50, and is used to provide moderate and stable light intensity to the shooting element 40, so that the captured image is clear and uniform, so as to test the self-cleaning effects of different initial states, different self-cleaning modes or different self-cleaning times by controlling variables.

[0060] Furthermore, the size of the opening 51 can be set according to the shooting element 40. For example, the opening 51 can be formed by the lack of a side panel of the dark box 50. This embodiment does not limit this.

[0061] Furthermore, in an embodiment provided by the present invention: an opening 51 is provided on the side of the dark box 50, and correspondingly, the shooting element 40 is also provided on the side, so as to shoot from the side of the roller brush A. The fill light element 52 is provided on the top wall of the dark box 50, so as to fill light from the top of the roller brush A. The fill light angle and the shooting angle in the above structure are fixed, so that images with sufficient and uniform brightness can be shot, so that the brightness of the shot pictures is uniform, which is convenient for comparison.

[0062] Furthermore, the above-mentioned fill light component 52 can be at least one, for example, can be two, respectively arranged on both sides of the top of the roller brush A. By filling light from both sides at the same time, the formation of shadows on the roller brush A can be avoided, and the fill light intensity is improved.

[0063] In one embodiment, the fill light element 52 may be a light-emitting diode (LED), which can fill light for the roller brush A through focus compensation to cooperate with the camera 40 to obtain a high-quality image.

[0064] Figure 3 This is the third structural diagram of the shooting device of the roller brush provided by the present invention, see Figure 3 Specifically, in an embodiment provided by the present invention, the shooting device of the roller brush further includes: a brightness sensor 60 and a controller.

[0065] The brightness sensor 60 is disposed in the dark box 50 and is opposite to the fill light element 52. The brightness sensor 60 generally refers to a light sensor, which can identify the brightness of the light at its location and feed back the brightness signal to the controller in real time.

[0066] The controller is respectively connected to the brightness sensor 60 and the fill light element 52 for controlling the luminous power of the fill light element 52 based on the brightness signal sent by the brightness sensor 60 , so as to achieve better fill light effect and shooting effect.

[0067] For further information, please see Figure 3 In one embodiment of the present invention, the roller brush shooting device further comprises: a bristle arrangement plate 70 disposed at the lower side of the rotating shaft 10 , and the bristle arrangement plate 70 has a brush tooth portion, and the brush tooth portion is used to abut against the outer wall of the roller brush A.

[0068] Furthermore, based on the rotation direction of the rotating shaft 10, the position of the bristle sorting plate 70 is located upstream of the shooting position. That is to say, in the process of the rotating shaft 10 driving the roller brush A to rotate, the roller brush A is sorted by the bristle sorting plate 70 before reaching the shooting position. This can improve the cleanliness of the surface of the roller brush A photographed. For the roller brush A corresponding to different initial states, different self-cleaning modes or different self-cleaning times, the above structure also unifies the roughness of its surface.

[0069] The brush tooth portion includes comb teeth arranged at intervals, which are used to comb the bristles on the surface of the roller brush A.

[0070] Furthermore, in an embodiment provided by the present invention, the brightness sensor 60 is disposed on a brush finishing plate 70 so as to fix the brightness sensor 60 .

[0071] Specifically, the brightness sensor 60 is disposed on the outer side of the bristle arrangement plate 70 so as to receive light without affecting the function of the bristle arrangement plate 70 .

[0072] Please continue to see Figure 3 In any of the above embodiments provided by the present invention, the shooting device of the roller brush further includes: a mounting frame 80, and the above-mentioned rotating shaft 10 is arranged on the mounting frame 80. Moreover, a card slot is provided on the bottom plate of the dark box 50 for positioning the mounting frame 80. Through the above structure, the positioning of the rotating shaft 10 is realized, so as to realize the unification of the shooting pictures, and also realize the standardized management of the shooting device.

[0073] Correspondingly, a corresponding alignment groove can also be set at the bottom of the shooting member 40 to achieve the positioning of the shooting member 40. That is to say, the relative position relationship between the roller and the shooting member 40 is fixed, and no displacement will occur during the replacement of the roller brush A or the shooting member 40, so that the specifications of the captured pictures are unified and easy to compare.

[0074] In an embodiment provided by the present invention, the above-mentioned shooting member 40 includes: a bracket 41, a rotating member 42 and a camera 43 connected in sequence. Among them, the bracket 41 is a telescopic structure, and the rotating member 42 can drive the camera 43 to rotate. Through the above structure, the position of the shooting member 40 can be adjusted up and down, and the shooting angle can be changed, making the shooting device more flexible and improving the convenience of use.

[0075] In one embodiment provided by the present invention, the power member 20 is a stepper motor. A stepper motor is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step. The angular displacement or linear displacement outputted is proportional to the number of pulses inputted, and the rotation speed is proportional to the pulse frequency. Therefore, the stepper motor can accurately control the angle of each rotation so as to cooperate with the camera 40 to rotate the roller brush A.

[0076] The shooting device of the roller brush provided in the embodiment of the present invention can be used to install the roller brush A by setting the rotating shaft 10. The roller brush A can be locked by setting the rotating wedge 30. The power member 20 can provide power for the rotating shaft 10, thereby driving the roller brush A to rotate by a preset angle. The shooting device is also provided with a shooting member 40 for shooting. Each time the roller brush A rotates, the shooting member 40 can shoot an image of the roller brush A. Thus, the image of the roller brush A can be shot by the above-mentioned shooting device, so as to observe the self-cleaning effect of the roller brush A, etc.

[0077] Furthermore, by being arranged on the outside of the rotating shaft 10, the power member 20 and the rotating wedge 30, the dark box 50 is a light-shielding structure formed by multiple plates, which is used to shield the outside of the roller brush A to prevent changes in external light from affecting the shooting effect. Moreover, the dark box 50 has an opening 51, and the shooting member 40 is arranged on the outside of the opening 51, so that the shooting member 40 can shoot the image of the roller brush A through the opening 51. Correspondingly, the shooting device of the roller brush also includes a fill light 52, which is arranged on the inner wall of the dark box 50, and is used to provide moderate and stable light for the shooting member 40, so that the captured image is clear and uniform, so as to test the self-cleaning effect of different initial states, different self-cleaning modes or different self-cleaning times by controlling variables.

[0078] The present invention provides a method for photographing a roller brush. Figure 4 is a flow chart of the method for photographing the roller brush provided by the present invention, see Figure 4 The shooting method of the roller brush includes:

[0079] Step 1: Install the roller brush A onto the rotating shaft 10 and stop the roller brush A with the rotating wedge block 30 .

[0080] In this step, the rotating wedge 30 in the photographing device is arranged at the end of the rotating shaft 10 and is detachable in the axial direction. When in use, after the roller brush A is installed, the rotating wedge 30 is pushed in the axial direction to stop the roller brush A and prevent the roller brush A from being separated from the end of the rotating shaft 10. The roller brush A can be stopped by setting the rotating wedge 30.

[0081] Step 2: Take an image of the side surface of the roller brush A through the camera 40.

[0082] Specifically, the image may be stored in the photographing element 40 , or may be transmitted to other devices in real time through the photographing element 40 , which is not limited in this embodiment.

[0083] Step 3: The power member 20 drives the rotating shaft 10 and the roller brush A to rotate by a preset angle, and continues to capture an image of the side surface of the roller brush A through the camera 40 .

[0084] In this step, the preset angle can be set as needed, and this embodiment does not limit this. For example, it can be 120°, so only three pictures need to be taken to cover the side of the roller brush A. The side of the roller brush A refers to the arc surface.

[0085] Step 4: Repeat step 3 until all images of the side of roller brush A are captured.

[0086] The power member 20 can drive the roller brush A to rotate a preset angle at one time. Each time the roller brush A stops rotating, the shooting member 40 is used to shoot once until the entire side of the roller brush A is shot. The shot pictures can be spliced ​​into a complete side picture of the roller brush A.

[0087] In a specific embodiment, the roller brush A can be of various types, such as a single-axis roller brush A, a double-axis crawler roller brush A, etc.

[0088] The method for photographing a roller brush provided by an embodiment of the present invention can be used to install a roller brush A by setting a rotating shaft 10. The roller brush A can be locked by setting a rotating wedge 30. The power member 20 can provide power to the rotating shaft 10, thereby driving the roller brush A to rotate at a preset angle. The photographing device is also provided with a photographing member 40 for photographing. Each time the roller brush A rotates, the photographing member 40 can photograph an image of the roller brush A. Thus, the above-mentioned photographing device can photograph an image of the roller brush A, so as to observe the self-cleaning effect of the roller brush A, etc.

[0089] Furthermore, a corresponding cleanliness test standard environment can be developed so as to extract the cleanliness of the roller brush before and after self-cleaning based on the above-mentioned images, and then judge the degree of dirtiness or self-cleaning effect.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
