[0041] In the toothbrush head production process, the feeding of toothbrush heads is a crucial step. With the development of technology, in order to improve the automation level and production efficiency of toothbrush head feeding, image acquisition components have been gradually applied to the automated feeding of toothbrush heads.

[0042] Existing image acquisition components typically use a camera to directly capture images of the toothbrush head and then transmit the images to the control system to detect the toothbrush head's position and status. However, in low-light conditions, existing image acquisition components cannot guarantee the clarity of the captured images of the toothbrush head, affecting image quality and consequently the accuracy of toothbrush head detection.

[0043] This invention proposes an image acquisition component to improve image quality and thus improve feeding accuracy.

[0044] Please see Figure 2 and Figure 3 In one embodiment, the image acquisition component 40 includes a support frame 410, a camera 420, and a surface light source module 430. The camera 420 is mounted on the support frame 410 and its shooting direction faces the toothbrush head. The surface light source module 430 is mounted on the support frame 410 and arranged around the camera 420. The light-emitting side 433 of the surface light source module 430 faces the toothbrush head. The surface light source module 430 is used to provide illumination for the camera 420 to capture images of the toothbrush head.

[0045] The image acquisition component 40 is used to capture images of the toothbrush head and transmit the images to the control system. The toothbrush head is suitable for electric toothbrushes and can be either a bristle-embedded or bristle-free toothbrush. The toothbrush head is placed on the operating platform, and the image acquisition component 40 captures images of the operating platform on which the toothbrush head is placed. The control system can identify the position and status of the toothbrush head on the operating platform based on the images.

[0046] The support frame 410 provides support and a mounting base for the image pickup component 40. In one embodiment, the support frame 410 is configured as a pole-type structure, with one end of the support frame 410 attached to the base 10 or other external mounting base. The support frame 410 and the base 10 or other external mounting base can be integrally formed or connected by screws or welding, etc., without limitation.

[0047] Camera 420 is used to photograph the toothbrush head. In one embodiment, the camera 420's shooting direction is towards the operating platform and towards the toothbrush head, and the camera 420's shooting range covers the operating platform. The side of the camera 420 away from the toothbrush head is mounted on the support frame 410 via a first bracket. In one embodiment, the first bracket and the support frame 410 are detachably connected by bolts or clips. Of course, in other embodiments, it can also be fixedly mounted on the support frame 410; this is not a limitation. The camera 420 is electrically connected to the control system. The camera 420 can be a color camera to clearly photograph the toothbrush head and facilitate image recognition by the control system.

[0048] The surface light source module 430 provides illumination for the camera 420 to capture images of the toothbrush head. In one embodiment, the surface light source module 430 includes a housing 431, a light source panel 432, and a circuit board (not shown). One side of the housing 431 is the light-emitting side 433, which faces the operating platform. The housing 431 has a receiving cavity, and the side of the housing 431 facing away from the toothbrush head is mounted on a support plate via a second bracket. The light source panel 432 is located in the receiving cavity and its light emission direction faces the light-emitting side 433. The circuit board is located in the receiving cavity and is electrically connected to the light source panel 432. The light-emitting side 433 of the housing 431 is light-transmitting to ensure that the light from the light source panel 432 can illuminate the operating platform. The surface light source module 430 is arranged around the outer periphery of the camera 420, so that the light-emitting surface of the light source panel 432 is arranged around the camera 420 to provide uniform illumination.

[0049] In this invention, the image acquisition component 40 is used to capture images of the toothbrush head and transmit them to the control system. The image acquisition component 40 includes a support frame 410, a camera 420, and a surface light source module 430. The camera 420 is mounted on the support frame 410, with its shooting direction facing the toothbrush head. The surface light source module 430 is mounted on the support frame 410 and surrounds the camera 420, with its light-emitting side 433 facing the toothbrush head. The surface light source module 430 provides illumination for the camera 420 to capture images of the toothbrush head. Compared to the prior art where the image acquisition component 40 directly uses the camera 420 to capture images of the toothbrush head, this invention provides a surface light source module 430. The surface light source module 430 surrounds the camera 420 with its light-emitting side 433 facing the toothbrush head, providing supplemental lighting to the toothbrush head and ensuring uniform illumination for the camera 420's capture of the toothbrush head. This improves the quality of the captured images and, consequently, the accuracy of the toothbrush feeding process.

[0050] In one embodiment, the image pickup component 40 further includes a light-diffusing plate (not shown) disposed on the light-emitting side 433 of the surface light source module 430.

[0051] In one embodiment, a light-diffusing plate is disposed within the receiving cavity and parallel to the light source panel 432. The light-diffusing plate is located between the light source panel 432 and the light-emitting side 433 of the housing 431, allowing the light emitted from the light source panel 432 to pass through both the light-diffusing plate and the light-emitting side 433. After passing through the light-diffusing plate, the light emitted from the light source panel 432 can be more uniformly distributed in space. In one embodiment, the light-diffusing plate includes a substrate and a light-guiding grid disposed on the substrate. The light-guiding grid consists of grooves arranged in a crisscross pattern. When the light emitted from the light source panel 432 passes through the substrate, the light-guiding grid guides the light. By rationally arranging the light-guiding grid, the brightness of the light at various positions on the light-diffusing plate can be balanced, thereby ensuring uniform light emission. In another embodiment, the light-diffusing plate includes multiple layers of microstructured films, which are stacked sequentially and all are transparent. The microstructures of adjacent layers are different, causing light to be refracted and scattered in different directions as it passes through the layers. By rationally arranging the microstructures of each layer, uniform light emission can be achieved. Of course, in other embodiments, the light-diffusing plate can also be configured as a micro / nano structure or a lens structure lamp; no limitation is made here.

[0052] The technical solution of this utility model embodiment, by setting a light-diffusing plate, can act on the light emitted by the surface light source module 430, so that the light is uniformly emitted to the light-emitting side 433, thereby improving the uniformity of illumination brightness and thus improving image quality.

[0053] In one embodiment, the surface light source module 430 is configured as an LED light source.

[0054] In one embodiment, the light source panel 432 includes multiple LED beads and a base plate. The multiple LED beads are electrically connected to a circuit board and are disposed on the base plate and uniformly arranged around the axis of the camera 420. In another embodiment, a light guide plate is provided between the LED beads and the light-diffusing plate to uniformly guide all the light emitted by the LED beads to the light-diffusing plate, thus forming a surface light source. The light-diffusing plate further homogenizes the light. The light guide plate may include light guide points, microlens arrays, etc., and is not limited thereto. Of course, in other embodiments, the surface light source module 430 may also be configured as a quantum dot light source, a light-emitting diode, or a fluorescent tube, etc., and is not limited thereto.

[0055] The technical solution of this utility model embodiment configures the surface light source module 430 as an LED light source. The power of the LED light source is adjustable, and the brightness can be adjusted by adjusting the power of the LED light source. Moreover, the LED light source has good fast response capability and long service life, which improves the reliability of the surface light source module 430.

[0056] Please see Figure 3 and Figure 4 In one embodiment, the surface light source module 430 has an avoidance channel 434 at its axial center position. The avoidance channel 434 is coaxially arranged with the camera 420, and the camera 420 extends to the avoidance channel 434.

[0057] In one embodiment, a through hole is provided at the axial position of the housing 431. The through hole and the outer wall of the receiving cavity together form a clearance channel 434, and the panel light source is arranged around the clearance channel 434. The lens of the camera 420 extends into the clearance channel 434, but the camera 420 does not penetrate the clearance channel 434. The sidewalls of the clearance channel 434 are opaque to provide a light-free channel for the camera 420. In one embodiment, the inner diameter of the through hole is larger than the outer diameter of the camera 420 to ensure that the lens of the camera 420 can extend into the clearance channel 434. The size of the through hole can be flexibly set according to the size of the camera 420 and actual needs, and is not limited here. Of course, in other embodiments, the surface light source module 430 can also be located on the side of the camera 420 facing away from the toothbrush head, and the camera 420 can be directly fixed to the axial position of the surface light source module 430, and is not limited here.

[0058] The technical solution of this utility model embodiment, by setting an avoidance channel 434, can prevent the light from the surface light source module 430 from directly shining on the lens of the camera 420, thus avoiding exposure. This achieves a reasonable arrangement of the surface light source module 430, ensures the normal use of the camera 420, and improves the reliability of the image pickup component 40.

[0059] In one embodiment, the light-emitting side 433 of the surface light source module 430 is provided with multiple annular light areas around the avoidance channel 434. The multiple annular light areas are coaxially arranged and sequentially arranged in a direction away from the camera 420. The multiple annular light areas work independently.

[0060] In one embodiment, the light source panel 432 forms multiple annular light areas according to the arrangement of LED beads. That is, multiple LED beads are arranged in multiple rings around the clearance channel 434, and each ring of LED beads constitutes an annular light area. The circuit board is electrically connected to each ring of LED beads to control each ring of LED beads individually, realizing the independent operation of the annular light area. In another embodiment, the LED light source can also be directly configured as multiple annular LED tubes with different outer diameters. The multiple annular LED tubes are layered on the clearance channel 434 and are all electrically connected to the circuit board. Each annular LED tube constitutes an annular light area, and the outer diameter of the multiple annular LED tubes gradually increases in the direction away from the clearance channel 434. Of course, in other embodiments, the light source panel 432 can also form multiple independently operating rectangular light areas or triangular light areas, etc., according to the arrangement of the light source. There are no limitations here.

[0061] The technical solution of this utility model embodiment, by setting multiple independently operating annular light zones, allows for individual adjustment of the power of the light source in each annular light zone, thereby improving the flexibility of the surface light source module 430 and further ensuring the uniformity of illumination.

[0062] Please see Figure 4 In one embodiment, the surface light source module 430 includes two independent light source panels 432, which are symmetrically arranged on opposite sides of the avoidance channel 434.

[0063] In one embodiment, the emitting surfaces of both light source panels 432 face the light-emitting side 433. Each of the two light source panels 432 has a notch on its adjacent side to avoid the avoidance channel 434 and to fit against the sidewall of the avoidance channel 434. Each light source panel 432 has multiple LED beads. The two light source panels 432 are symmetrically arranged and have the same size, symmetrically distributed on both sides of the avoidance channel 434. The LED beads of both light source panels 432 are electrically connected to a circuit board to enable independent operation of the two light source panels 432. Of course, in other embodiments, the entire light source panel 432 of the surface light source module 430 can also be integrally formed; this is not a limitation.

[0064] The technical solution of this utility model embodiment, by setting two independent light source panels 432, allows for individual adjustment of the light intensity on one side of the avoidance channel 434, avoiding the influence of shadows or natural light. Furthermore, the separate design of the light source panels 432 facilitates manufacturing and assembly / disassembly, prevents heat concentration, and promotes heat dissipation.

[0065] In one embodiment, the light-emitting area of ​​the light-emitting side 433 of the surface light source module 430 is greater than or equal to 0.25 square meters and less than or equal to 0.3 square meters.

[0066] In one embodiment, the light-emitting area of ​​the surface light source module 430 is adapted to the area of ​​the operating platform. The area of ​​the operating platform is typically between 0.25 square meters and 0.3 square meters. Setting the light-emitting area within this range ensures that the light emitted by the surface light source module 430 can cover the entire operating platform. The specific value of the light-emitting area can be flexibly set according to the area range of the operating platform and is not limited here.

[0067] The technical solution of this utility model embodiment ensures that the illumination range of the surface light source module 430 covers the entire operating platform by limiting the light-emitting area of ​​the light-emitting side 433 of the surface light source module 430. This allows the camera 420 to clearly capture images of various positions on the operating platform, ensuring image integrity and thus improving the integrity and accuracy of the detection.

[0068] Please see Figure 1 and Figure 2This utility model also proposes a toothbrush head feeding machine, including a control system, a base 10, a vibration component 20, and an image pickup component 40 as described in the above embodiments. Both the vibration component 20 and the image pickup component 40 are disposed on the base 10. The vibration component 20 is used to arrange the toothbrush heads, and the image pickup component 40 is disposed above the vibration component 20. The shooting direction of the camera 420 of the image pickup component 40 and the light-emitting side 433 of the surface light source module 430 both face the vibration component 20. The camera 420 of the image pickup component 40 is electrically connected to the control system. The specific structure of the image pickup component 40 is as described in the above embodiments. Since this toothbrush head feeding machine adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0069] In one embodiment, the vibration component 20 carries the toothbrush heads and arranges them through vibration. The toothbrush heads are placed on the vibration component 20, which serves as the operating platform. The camera 420 and the surface light source module 430 of the image acquisition component 40 are located directly above the vibration component 20, and the shooting range of the camera 420 and the illumination range of the surface light source module 430 both cover the vibration component 20. The images captured by the camera 420 are transmitted to the control system, which determines the state and position of the toothbrush heads based on the images to control other functional components to operate. The control system includes a controller and a processing unit, and its specific functions are mainly implemented through logic algorithms, which are not limited here.

[0070] Please see Figure 2 and Figure 5 In one embodiment, the vibration assembly 20 includes a base 210, a vibrating plate 220, and a power component. The base 210 is disposed on the base 10. The vibrating plate 220 is disposed on the base 210 and includes a reflective base plate 221, which is used to support the toothbrush head and reflect the light from the surface light source module 430. The power component is disposed on the base 210 and is drivenly connected to the vibrating plate 220 to drive the vibrating plate 220 to vibrate.

[0071] In one embodiment, the base 210 has an internal mounting groove, the opening of which faces away from the base 10. A vibratory feeder 220 is disposed on top of the base 210 and covers the opening of the mounting groove. A power component is disposed within the mounting groove and located at the bottom of the vibratory feeder 220, and is electrically connected to the control system. The base 210 can be made of plastic or metal, and the power component can be configured as a motor or cylinder, etc., without limitation. In one embodiment, the vibratory feeder 220 includes a base plate and a baffle 222, covering the opening of the mounting groove and driven by the power component. The baffle 222 is disposed around the periphery of the side of the base plate facing away from the mounting groove. The area of ​​the base plate ranges from 0.25 square meters to 0.3 square meters. A positioning element (not shown in the figure) is provided on the base plate, allowing toothbrush heads to be inserted into the positioning element for toothbrush head arrangement. A reflective surface is provided on the side of the base plate facing away from the mounting groove, making the base plate a reflective base plate 221.

[0072] In one embodiment, the reflective substrate 221 is configured as a white substrate, which can be formed by coating a white coating on its surface to create a reflective surface. The white substrate has a high reflectivity. In another embodiment, the reflective substrate 221 is configured as a diffuse reflective substrate, which can be formed by providing a diffuse reflective film on its surface to create a reflective surface. The diffuse reflective substrate can scatter light in all directions. Of course, in other embodiments, the substrate may also be coated with other light colors such as light gray or beige; or, a reflective enhancement film may be provided on the surface of the substrate. There are no limitations on this.

[0073] The technical solution of this utility model embodiment, by setting the bottom plate of the vibrating plate 220 as a reflective bottom plate 221, can effectively reflect the light of the surface light source module 430, so that the light illuminating the bottom plate is evenly dispersed, providing a bright and uniform reference background for the image pickup component 40; the reflective bottom plate 221 can also enhance the light reflection effect of the surface light source module 430, making the features of the toothbrush head on the reflective bottom plate 221 more obvious, and improving the contrast of the image.

[0074] Please see Figure 2 and Figure 5 In one embodiment, the toothbrush head feeding machine further includes a hopper assembly 30, which includes a hopper body 310, a conveying unit, and an oscillating comber 330. The hopper body 310 is disposed on the base 10. The conveying unit is movably disposed at the bottom of the hopper body 310 and forms a receiving groove together with the hopper body 310. The discharge end of the conveying unit is disposed near the vibration assembly 20. The oscillating comber 330 is disposed at the discharge end of the conveying unit and is used to comb the toothbrush head.

[0075] The hopper assembly 30 is used to store toothbrush heads and convey them to the vibration assembly 20. In one embodiment, the conveying unit includes an inclined platform 321, a conveyor belt 322, and a first driving member. The inclined platform 321 is mounted on the base 10 via a support plate. The end of the inclined platform 321 away from the base 10 is the discharge end, which is located near the vibration assembly 20 and above the vibrating plate 220. The conveyor belt 322 is movably mounted on the platform 321. The first driving member is located on the platform 321 and is drivenly connected to the conveyor belt 322 to drive the conveyor belt 322 to rotate around the platform 321 and move the toothbrush heads. In one embodiment, the hopper body 310 has a bottom opening. The hopper body 310 is located above the platform 321, and the periphery of the opening is connected to the platform 321. The hopper body 310 and the conveying unit 320 together form a receiving groove to store toothbrush heads. In one embodiment, the hopper body 310 is provided with a guide plate 311, which is located at the discharge end and inclined toward the vibration assembly 20 to guide the toothbrush head into the vibration assembly 20. In one embodiment, the oscillating comber 330 includes a comb tooth structure 331 and a second drive member 332. The second drive member 332 is mounted on the base 10 via a mounting bracket and is located above the discharge end of the transport unit 320. The comb tooth structure 331 is connected to the output shaft of the second drive member 332 and is located near the conveyor belt 322. A second power member drives the comb tooth structure 331 to reciprocate in a direction perpendicular to the transport direction, allowing the toothbrush head to pass through the gaps between adjacent comb teeth of the comb tooth structure 331. Both the first drive member and the second drive member 332 are electrically connected to the control system. The first drive member and the second drive member 332 can be motors or cylinders, etc., and are not limited herein.

[0076] When the drive unit is started, the conveyor belt 322 will move the toothbrush heads in the receiving groove, so that the toothbrush heads move from the feeding end of the transport unit 320 to the discharging end; the vibrating comb combs the toothbrush heads that are close to the discharging end, and the comb teeth of the comb structure 331 make the toothbrush heads pass through the discharging end one by one, and then fall onto the vibrating plate 220 of the vibrating component 20, thus realizing the transmission of the toothbrush heads.

[0077] The technical solution of this utility model embodiment, by setting an oscillating comber 330 in the hopper assembly 30, can prevent multiple toothbrush heads from overlapping and falling into the vibration assembly 20 from the hopper assembly 30, making it easier for the image acquisition assembly 40 to take pictures of the toothbrush heads on the vibrating plate 220, thus improving the accuracy of detection.

[0078] Please see Figure 1In one embodiment, the toothbrush head feeding machine further includes a handling robot 50, a conveying component 60, and a discharging robot 70. The handling robot 50 is used to transport the toothbrush heads on the vibration component 20 to the conveying component 60, the conveying component 60 is used to transport the toothbrush heads, and the discharging robot 70 is used to transport the toothbrush heads from the conveying component 60 to the subsequent workstation. The control system is electrically connected to each functional component.

[0079] After the hopper assembly 30 transports and combs the toothbrush heads, they fall from the discharge end of the hopper assembly 30 to the vibration assembly 20. The image acquisition assembly 40 captures an image of the vibration assembly 20 and transmits it to the control system. When the control system determines from the image that there are arranged toothbrush heads on the vibration assembly 20, it controls the handling robot 50 to move all the arranged toothbrush heads on the vibration assembly 20 to the material conveying assembly 60. The material conveying assembly 60 moves the toothbrush heads to the discharge end, and the control system controls the unloading robot 70 to move the toothbrush heads to the subsequent workstation.
