[0024] The present invention will be further described in detail below with reference to the accompanying drawings.
[0025] Example: Refer to Figures 1-5 The present invention discloses an automatic identification system for a lotus seed core-removing machine, comprising:
[0026] The substrate 1 has a cavity shell 2 at its top end, and a mounting cover 3 is provided at the top end of the cavity shell 2.
[0027] The top of the substrate 1 is provided with a guide rail groove 4, and the cavity shell 2 is provided with a channel 5 at the position corresponding to the guide rail groove 4. The top of the substrate 1 and both sides of the guide rail groove 4 are provided with mounting brackets 6. The inner side of the mounting brackets 6 is provided with identification components 7. The upper end of the substrate 1 and both sides of the identification components 7 are provided with light-emitting components 8.
[0028] In this embodiment, as a preferred embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the guide groove 4 is used to guide the chain. The chain is slidably disposed inside the guide groove 4, and the chain is provided with rollers for supporting lotus seeds inside the chain. A groove for supporting lotus seeds is provided between the two rollers.
[0029] When the device is in use, the lotus seeds pass through the guide rail groove 4 and channel 5 via a chain. As the chain moves, it actuates the light-emitting component 8, causing the light emitted by the light-emitting component 8 to vibrate. At this time, a more obvious change in light and shadow will appear on the surface of the lotus seeds. The lotus seeds are then photographed by the recognition component 7. Through the real-time change in light and shadow, the problem of inaccurate shooting and recognition caused by large areas of shadow on the surface of the lotus seeds due to external light can be effectively avoided.
[0030] In a further preferred embodiment of this utility model, such as Figure 4As shown, the identification component 7 includes an adjustment frame 71, which is connected to the mounting bracket 6 via several electric push rods. A fixing groove 72 is provided on the inner side of the adjustment frame 71, and a photovoltaic magnifying lens 73 is provided inside the fixing groove 72. A photovoltaic cable 74 is provided at the tail end of the photovoltaic magnifying lens 73.
[0031] In this embodiment, the adjustment frame 71 is connected to the mounting bracket 6 via an electric push rod. When the electric push rod extends or retracts, the position of the adjustment frame 71 can be effectively adjusted. The fixing slot 72 is used to fix and install the photovoltaic magnifying lens 73, and the photovoltaic cable 74 works with the photovoltaic magnifying lens 73 to identify and detect lotus seeds.
[0032] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 5 As shown, the light-emitting component 8 includes a positioning shaft 81, which is fixedly connected to the substrate 1. A lamp plate 82 is fixedly disposed on the outer peripheral wall of the positioning shaft 81, and a reset component is disposed on the top of the lamp plate 82.
[0033] In this embodiment, the light panels 82 are all tilted and face the center between the two recognition components 7. At this time, the light emitted by the light panels 82 will be concentrated at the center, so that the light is gathered around the detection position of the recognition component 7, thereby reducing the shadow area and improving the recognition accuracy.
[0034] In a further preferred embodiment of this utility model, such as Figure 5 As shown, light-concentrating plates 9 are provided on both sides of the light panel 82.
[0035] In this embodiment, the light-gathering effect is further enhanced by the setting of the light-concentrating plate 9, thus avoiding the generation of shadows.
[0036] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 5 As shown, the reset assembly includes a sleeve 83, which is sleeved on the top end of the positioning shaft 81. The top end of the sleeve 83 is fixedly connected to the mounting cover plate 3. A torsion spring 84 is provided inside the sleeve 83. The bottom end of the torsion spring 84 is fixedly connected to the positioning shaft 81, and the top end of the torsion spring 84 is fixedly connected to the mounting cover plate 3.
[0037] In this embodiment, the sleeve 83 is used to install the torsion spring 84. When the chain moves and pushes the lamp plate 82 to deflect at an angle, it will drive the torsion spring 84 to rotate, allowing the torsion spring 84 to accumulate potential energy. After the chain releases the lamp plate 82, the torsion of the torsion spring 84 will release the potential energy, causing the lamp plate 82 to return to its initial angle. This allows for continuous changes in the illumination angle of the lamp plate 82, which can improve the light and shadow changes on the surface of the lotus seeds and improve the recognition accuracy.
[0038] In a further preferred embodiment of this utility model, such as Figure 5 As shown, the bottom end of the lamp panel 82 is provided with an extension guide rail 85, and the inner side of the extension guide rail 85 is provided with a buffer plate 86.
[0039] In this embodiment, the extension guide rail 85 is used to install the buffer plate 86. After the chain moves, the protrusions at both ends of the chain connecting pin contact the buffer plate 86. The buffer plate 86 drives the lamp plate 82 to move. When the buffer plate 86 collides with the protrusions at both ends of the connecting pin, it can also reduce the impact force and improve the service life of the lamp plate 82.
[0040] The implementation principle of the above embodiment is as follows: the guide groove 4 is used to guide the chain. The chain is slidably set inside the guide groove 4. The lotus seeds pass through the guide groove 4 and the channel 5 via the chain. During the movement of the chain, the protrusions at both ends of the chain connecting pin contact the buffer plate 86. The buffer plate 86 drives the lamp plate 82 to move, which will drive the torsion spring 84 to rotate, so that the torsion spring 84 accumulates potential energy. After the chain connecting pin separates from the buffer plate 86, that is, after the lamp plate 82 is released, the torsion of the torsion spring 84 releases the potential energy, and the lamp plate 82 returns to the initial angle. In this way, the illumination angle of the lamp plate 82 is continuously changed, so as to improve the light and shadow changes on the surface of the lotus seeds and achieve the effect of improving the recognition accuracy.
[0041] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
