DETAILED DESCRIPTION

[0023] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0024] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0025] Example:

[0026] like Figure 1 As shown, a guide plate is used to sort goods into a material box 2. The guide plate includes a bottom plate 31 extending toward an opening of the material box 2. The guide plate has an inlet 312 and an outlet 311 opened at opposite ends of the bottom plate 31. The guide plate 3 also includes a plurality of material sensors 13. The plurality of material sensors 13 are arranged at intervals along a set direction, and the set direction intersects with the material guiding direction of the bottom plate 31.

[0027] In this embodiment, a guide plate suitable for connecting between a storage robot and a material box 2 is provided, and the guide plate is used to guide the material on the belt of the storage robot to the material box 2 to complete the sorting. The guide plate includes a bottom plate 31 extending toward the opening of the material box 2, and the bottom plate 31 has an inlet 312 toward the storage robot and an outlet 311 toward the material box 2. The material slides from the inlet 312 to the outlet 311 along the bottom plate 31, and finally enters the material box 2. The material sensor 13 can detect the distance between itself and the material in the material box 2. When the material in the material box 2 accumulates, the material sensor 13 will detect that the distance with the material is constantly decreasing. When the distance value detected by the material sensor 13 is less than a preset value or equal to 0, it can be determined that the material in the material box 2 is full, indicating that it is necessary to stop sorting or take measures. If it is not full, the material can continue to be sorted, thereby improving the sorting efficiency. Multiple material sensors 13 are arranged at intervals along a set direction, and the set direction intersects with the material guiding direction of the bottom plate, thereby expanding the detection range of the sensor. The material sensor 13 in this embodiment is easy to install. It only needs to be installed on the bottom plate 31. It does not need to be arranged on both sides of the outlet 311 and aligned like the infrared material sensor 13 in the prior art, which reduces the difficulty of installation.

[0028] The plurality of material sensors 3 are arranged in a linear array 1 , and a mounting groove is provided on the bottom plate 31 along a set direction, and the plurality of material sensors 3 are arranged in the mounting groove.

[0029] The bottom plate 31 is provided with an installation groove along a set direction, and a plurality of material sensors 13 are arranged in a linear array 1 at a certain interval to form a linear and continuous sensing area. In addition, the material sensor 13 is highly stable in the installation groove and will not easily shift its position.

[0030] Along the set direction, the length of the linear array 1 matches the length of the outlet 311 .

[0031] The length of the linear array 1 matches the length of the outlet 311, ensuring that the state of the material box 2 can be effectively monitored. That is, the entire outlet 311 area is monitored by the material sensor 13, which expands the detection range of the material sensor 13 and can simultaneously measure the material accumulation conditions at different positions of the material box 2, avoiding the situation where part of the material box 2 is full.

[0032] The distance between the installation groove and the outlet 311 is smaller than the distance between the installation groove and the inlet 312 .

[0033] In this embodiment, Figure 1It can be shown that the mounting groove is opened near the outlet 311, that is, the material sensor 13 is arranged near the outlet 311, so as to detect whether the material in the material box 2 is accumulated at the guide plate. In addition, the inlet 312 of the guide plate is larger than the outlet 311, which plays a role of closing the mouth, so that the material can be sorted from the storage robot to the material box 2 more accurately and quickly.

[0034] The guide plate 3 further includes side plates 32 disposed at both ends of the bottom plate 31 . The side plates 32 and the bottom plate 31 define an inlet 312 and an outlet 311 .

[0035] Side plates 32 are provided at both ends of the bottom plate 31, and the side plates 32 and the bottom plate 31 define an inlet 312 and an outlet 311. The guide plate is structured as a groove, and the side plates 32 provided at both ends form baffles. Due to the protection of the baffles, the materials can be prevented from falling during the sorting process, and the materials can be sorted from the storage robot to the material box 2 more quickly and smoothly.

[0036] The material sensor 13 is a laser distance sensor.

[0037] In this embodiment, the material sensor 13 is constructed as a laser distance sensor. The distance measurement principle of the laser distance sensor is mainly based on the emission, propagation, reception and time calculation of the laser. The laser distance sensor can generate a pulsed laser beam, which will propagate to the object to be measured at the speed of light. When the laser beam is irradiated on the object to be measured (in this embodiment, the material in the material box 2), a part of the laser beam will be reflected back by the object, and the laser distance sensor is also equipped with a receiver for receiving the reflected laser beam. The receiver will convert the reflected laser beam into an electrical signal and transmit this signal to the processor of the laser distance sensor. The laser distance sensor records the emission time and reception time of the laser beam, and calculates the time difference required from the emission to the reception of the laser beam. The distance between the object to be measured and the laser distance sensor can be calculated using the speed of light and the time difference. When the distance measured by the laser distance sensor to the material is less than a preset value, it can be determined that the material box 2 is full.

[0038] The guide plate further includes a housing 11 for accommodating the material sensor 13 . The housing 11 is provided with a plurality of light outlets corresponding to the emission ports of the material sensor 13 . A polarizing plate 114 is disposed at the light outlets.

[0039] In this embodiment, the guide plate also includes a flattened housing 11, which can adapt to different installation environments and space restrictions, and the housing 11 also provides sufficient internal space to accommodate the circuit board 12, the material sensor 13 and other necessary electronic components. The flattened housing 11 improves the integration of multiple material sensors 13, and the structure of multiple material sensors 13 is more compact, which is convenient for installation in different environments. Specifically, in this embodiment, the thickness of the housing 11 is 1.2 cm and the width is 2 cm. The length of the housing 11 is lengthened or shortened according to the spacing and number of the material sensors 13, and the spacing and number of the material sensors 13 depend on the size of the material box 2. In addition, the smaller the spacing between adjacent material sensors 13, the smaller the detectable object, and the more the number of material sensors 13, the larger the detectable object. Of course, in other embodiments, the width and thickness of the housing 11 can also be other similar sizes, as long as the width and thickness of the housing 11 are small. In this embodiment, each light outlet corresponds to the emission port of the material sensor 13 one by one, ensuring that the laser can be accurately emitted from the material sensor 13 and pass through the housing 11 to the target object. Specifically, the shape and size of the light outlet need to be designed according to the characteristics of the laser beam and the requirements of the material sensor 13 to minimize the scattering and energy loss of the laser. In addition, a polarizing plate 114 is also configured at the light outlet, which can filter out ambient light with a different polarization direction from the laser, reduce interference, and improve the accuracy and stability of ranging.

[0040] like Figure 2 and Figure 3 As shown, the housing 11 includes a top shell 111 and a bottom shell 112 that are fixedly connected. The top shell 111 is configured as a U-shaped groove opening toward the bottom shell 112 , and the bottom shell 112 has a protrusion 1121 extending toward the top shell 111 and extending into the top shell 111 .

[0041] In this embodiment, the top shell 111 has space for accommodating the circuit board 12, the material sensor 13 and other necessary electronic components. In addition, in order to protect the internal components from the external environment such as dust and moisture, the top shell 111 can also adopt a waterproof and dustproof sealing design. The separation design of the top shell 111 and the bottom shell 112 makes installation and maintenance more convenient. If the circuit board 12 or the material sensor 13 needs to be replaced or repaired, the bottom shell 112 can be easily opened for operation. Specifically, the top shell 111 and the bottom shell 112 are fixedly connected by fasteners such as screws. The shape of the top shell 111 is a U-shaped groove, that is, it has an open bottom and two relatively parallel sides. This structure enables the top shell 111 to accommodate the circuit board 12, the laser ranging material sensor 13 and other necessary electronic components, and has a high supporting strength to prevent the circuit board 12 from bending. Specifically, the top shell 111 is made of aluminum alloy material. The bottom shell 112 is made of ABS material, which is a thermoplastic polymer material with high strength, good toughness, and easy processing and molding. It has high strength, corrosion resistance, and high temperature resistance. The opening of the U-shaped groove faces the bottom shell 112 , so that the protrusion 1121 of the bottom shell 112 can extend into the interior of the top shell 111 , thereby achieving a tight connection between the two.

[0042] The guide plate further includes a circuit board 12 , and a plurality of material sensors 13 are electrically connected and arrayed on the circuit board 12 .

[0043] In this embodiment, a plurality of material sensors 13 are electrically connected and arrayed on a circuit board 12 to form a linear array 1 .

[0044] A CAN communication module electrically connected to the plurality of material sensors 13 is disposed on the circuit board 12 .

[0045] In this embodiment, the circuit board 12 is provided with a CAN communication module, which is connected to the power module through the line on the circuit board 12 to form a complete CAN bus communication system. The CAN bus adopts differential signal transmission, and usually only two signal lines are needed for normal communication, thereby greatly reducing the number of electrical connections. In addition, multiple material sensors 13 exchange data through the I2C communication protocol.

[0046] In this embodiment, an insulating sheet for covering the circuit board 12 is disposed between the circuit board 12 and the housing 11. The insulating sheet can isolate the external interference to the circuit board 12 and ensure that there is no electrical connection or interference between the wires of different layers on the circuit board 12, which helps to prevent problems such as circuit failure, current leakage or short circuit. The insulating sheet not only plays the role of separating and protecting the wires, but also provides structural stability and mechanical strength for the circuit board 12. This can increase the rigidity of the PCB as a whole and help resist the influence of external stress or vibration on the circuit.

[0047] In this embodiment, electrical interfaces 113 electrically connected to the circuit board 12 are provided at both ends of the housing 11, and the electrical interface 113 is configured as a bidirectional interface. A bidirectional interface means that the electrical interface 113 can both input signals internally and output signals externally, so that the detection device can flexibly exchange and communicate data with external devices or systems, thereby improving the flexibility and scalability of the detection device. In addition, the electrical interface 113 is arranged at both ends of the housing 11 to facilitate connection with external devices or systems. In summary, the electrical interface 113 in this embodiment can effectively reduce the number of electrical connections and reduce the complexity and cost of the system.

[0048] In this embodiment, the housing 11 is provided with an adjustment knob electrically connected to the circuit board 12. The adjustment knob is electrically connected to the circuit board 12 through an internal circuit. The adjustment knob is usually implemented by a conductive element (such as a metal sheet, a carbon film, etc.), and when the knob is rotated, these conductive elements will change their contact state or resistance value, thereby changing the current or voltage in the circuit, and then adjusting the detection range of the laser ranging material sensor 13.

[0049] In this embodiment, an indicator light 115 is installed in the housing 11 and the housing 11 is provided with a plurality of openings corresponding to the indicator lights 115. The indicator light 115 can intuitively display the state of the material box 2. For example, when the material box 2 is full, the indicator light 115 lights up to remind the user to unload the material. In other embodiments, the indicator light 115 can also be used to display the power state, working mode, measurement state, etc. of the detection device.

[0050] This embodiment further provides a sorting system, which includes a material box 2 and a guide plate, and the guide plate includes the aforementioned guide plate.

[0051] In this embodiment, in the sorting system, the storage robot first moves to the designated position through the intelligent navigation system and grabs the goods to be sorted from the material box 2. Then, the storage robot places the goods at the inlet 312 of the guide plate, and the goods move along the bottom plate 31 to the outlet 311 under the guidance of the guide plate, and finally the materials enter the material box 2. Through continuous cycle operation, the sorting system can quickly and accurately complete the sorting task of a large number of materials.

Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
