Description

Technical Field

[0001] The present disclosure relates to the field of electronics, and more particularly to a picking device. Background Art

[0002] Since picking devices can improve the picking efficiency and accuracy of pickers, picking devices are widely used in fields such as e-commerce logistics warehouses, pharmaceuticals, food processing, and electronics manufacturing. In particular, in scenarios with high-mix and small-batch order processing, the role of picking devices is particularly evident.

[0003] Picking devices usually use buttons or RFID (Radio Frequency Identification) to assist pickers in completing material picking. For example, the picking system sends an order to the picking device, the picking device lights up, and after the picker picks the material according to the order, by pressing the button on the picking device, the picking device turns off the light, indicating that the material picking for this order is completed. Another example is that the picking system sends an order to the picking device, the picking device lights up, and after the picker picks the material according to the order, the picker brings the RFID bracelet worn on his / her body close to the picking device. After the picking device reads the RFID bracelet information, the light turns off, indicating that the material picking for this order is completed.

[0004] In the process of implementing the present disclosure, the inventors found that for button-type picking devices, the action of the picker pressing the button is usually a relatively delicate action. When the picker has materials in hand, it is not convenient to press the button. In addition, relatively delicate actions often require the picker to spend more time and energy. For RFID-type picking devices, the installation position of the picking device is subject to certain restrictions. For example, if two picking devices are close to each other, it may cause misreading problems.

[0005] How to use a picking device to complete material picking conveniently and accurately is a technical issue worthy of attention. Summary of the Utility Model

[0006] In order to solve the above technical problems, the present disclosure is proposed. An embodiment of the present disclosure provides a picking device.

[0007] According to an embodiment of the present disclosure, a picking device is provided, including: a housing 1, a core board module 2, a controller area network (CAN) bus interface 3, an optoelectronic module 4, a fixing structure member 5, and an infrared filter 6; the core board module 2, the CAN bus interface 3, the optoelectronic module 4, the fixing structure member 5, and the infrared filter 6 are respectively disposed in the housing 1, and a light hole 7 is provided on the housing 1, and the position of the light hole 7 is adapted to the position of the optoelectronic module 4; the core board module 2 includes: a single-chip microcomputer; the CAN bus interface 3 is electrically connected to the core board module 2, and the picking device is electrically connected to a picking gateway through the CAN bus interface 3; the optoelectronic module 4 is electrically connected to the core board module 2, and the optoelectronic module 4 includes: a photoelectric emitting tube for emitting infrared light and a photoelectric receiving tube for receiving the diffuse reflected light of the infrared light; the fixing structure member 5 fixes the optoelectronic module 4 at a position in the housing 1 adapted to the light hole 7; the infrared filter 6 is disposed on the front side of the photoelectric emitting tube and the photoelectric receiving tube, and the infrared light emitted by the photoelectric emitting tube passes through the infrared filter 6 and is emitted outside the picking device through the light hole 7, and the diffuse reflected light of the infrared light emitted outside the picking device enters the photoelectric receiving tube through the light hole 7 and then passes through the infrared filter 6.

[0008] A picking device provided based on the above embodiments of the present disclosure fixes the optoelectronic module 4 in the housing 1 by using the fixed structural member 5, and sets an optical hole in the housing 1, so that the invisible infrared light emitted by the optoelectronic emitter included in the optoelectronic module 4 in the picking device irradiates the hand of the picker, and the diffusely reflected infrared light generated by the hand can return to the optoelectronic receiver in the picking device, so that the picking gateway can obtain the information that the material picking is completed through the CAN bus interface 3 and the core board module 2; since making the hand generate diffusely reflected infrared light does not belong to fine operations, when the hand of the picker is in a non-idle state (such as the picking operation with the material in the hand), diffusely reflected infrared light can also be conveniently generated. Therefore, it is beneficial to avoid the consumption of time and energy caused by the picker performing fine actions, and since the picking operation of the material can trigger the generation of the information that the material picking is completed at the same time, it is beneficial to further shorten the material picking time; since the diffusely reflected infrared light needs to return to the optoelectronic receiver in the picking device through the optical hole, even if the distance between two picking devices is relatively close, they usually do not interfere with each other, so it is beneficial to avoid the problem that the installation position of the picking device is limited. In addition, the optoelectronic module 4 has good sensitivity to generate corresponding electrical signals according to the diffusely reflected infrared light, so that the picking device has good sensitivity for identifying the completion of material picking. By setting the infrared filter 6, light sources other than infrared light can be effectively filtered out, which is not only beneficial to improving the anti-interference ability of the optoelectronic module 4, but also beneficial to preventing damage to the components caused by strong light irradiating the optoelectronic module 4. It can be seen from this that the technical solution provided by the present disclosure is beneficial to assisting the picker to complete the material picking conveniently, quickly and accurately, and is beneficial to enriching the implementation methods of material picking.

[0027] It should also be understood that the descriptions of the various embodiments in this disclosure emphasize the differences between the various embodiments, and their similarities or resemblances can be referred to each other. For the sake of brevity, they will not be elaborated one by one.

[0028] Meanwhile, it should be understood that, for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0029] The following description of at least one exemplary embodiment is actually merely illustrative and in no way constitutes any limitation to this disclosure and its application or use.

[0030] The technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0031] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0032] The following Figures 1 to 11 will detail the exemplary structure of the picking device of this disclosure.

[0033] As shown in the figure, the picking device of this disclosure mainly includes: a housing 1, a core board module 2, a CAN (Controller Area Network) bus interface 3, an optoelectronic module 4, a fixed structural member 5, and an infrared filter 6.

[0034] The housing 1 is mainly used to form an accommodation space to accommodate components such as the core board module 2, the CAN bus interface 3, the optoelectronic module 4, the fixed structural member 5, and the infrared filter 6 therein. A light hole 7 is provided on the housing 1, and the position of the light hole 7 is adapted to the position of the optoelectronic module 4. That is, the optoelectronic module 4 performs optical interaction with the outside of the picking device through the light hole 7. The shape of the light hole 7 of this disclosure can be a rectangle with rounded corners (as Figure 4 shown), or it can be other shapes, such as a circle, etc. Using a light hole in the shape of a rectangle with rounded corners is beneficial for the arrangement positions of the photoelectric emitter and the photoelectric receiver in the optoelectronic module 4 not to be too compact, thus being beneficial for improving the anti-interference ability of the optoelectronic module 4.

[0035] The core board module 2 is fixedly arranged in the housing 1, and the core board module 2 is electrically connected to components such as the bus interface 3, the optoelectronic module 4, the working indicator light in the picking device, the digital display screen, and the picking device switch respectively. The electrical connection in the present disclosure includes: the connection for providing power resources and the connection for transmitting communication signals. The core board module 2 can be called the main control chip or the main control unit of the picking device. In one example, the core board module 2 can be a single-chip microcomputer (which can also be called a microcontroller). That is to say, the core board module 2 is a microcomputer that integrates components such as a CPU (Central Processing Unit), a ROM (Read-Only Memory), a RAM (Random Access Memory), and an I / O (Input / Output) interface on one chip. The present disclosure does not limit the specific components included in the core board module 2.

[0036] The CAN bus interface 3 is fixedly arranged in the housing 1, and the CAN bus interface 3 is electrically connected to the core board module 2. The picking device is electrically connected to the picking gateway through the CAN bus interface 3, so that the picking device is connected to the picking system. In one embodiment, signals such as control commands (such as picking orders) sent by the picking gateway are transmitted to the core board module 2 in the picking device through the CAN bus interface 3, and the core board module 2 processes the received control commands and other signals. The core board module 2 can send the processing results (such as the information that the material picking is completed) to the picking gateway through the CAN bus interface 3. The CAN bus interface 3 can specifically be a Phoenix terminal interface, an M12 terminal interface, an RJ10 (Registered Jack) interface, or an RJ45 interface, etc. In one example, the CAN bus interface 3 can include a plurality of bus pins 31 (such as Figure 5 and Figure 6 the two bus pins 31 shown), and the bus pins 31 are inserted into the connection line between the picking device and the picking gateway to connect the signal connection between the picking device and the picking gateway, so that the picking device and the picking gateway can achieve information interaction.

[0037] The optoelectronic module 4 is electrically connected to the core board module 2. The optoelectronic module 4 of the present disclosure is an infrared-based optoelectronic module. In one example, the optoelectronic module 4 is generally an optoelectronic integrated chip. For example, the optoelectronic module 4 can be a photodiode chip. The optoelectronic module 4 is mainly used to convert an electrical signal into an infrared light signal and emit it, and convert the received infrared light signal into an electrical signal. Specifically, the optoelectronic module 4 emits infrared light under the control of the core board module 2, and converts the received infrared light into a corresponding electrical signal and transmits it to the core board module 2. In one example, the optoelectronic module 4 includes: a photoelectric emission tube for emitting infrared light, and a photoelectric receiving tube for receiving diffusely reflected infrared light.

[0038] The fixing structure 5 is fixedly arranged in the housing 1, and the function of the fixing structure 5 is to fix the optoelectronic module 4 at a position in the housing 1 adapted to the light hole 7. The fixing structure 5 can be a fixing structure made of a black matte material to reduce the reflection of infrared light in the housing 1. In one example, the material of the fixing structure 5 can be black matte plastic.

[0039] In one example, the fixing structure 5 includes: a first limiting member 51 and a second limiting member 52. The shapes of the first limiting member 51 and the second limiting member 52 can be cylinders with through holes (such as square cylinders, etc.), and the through holes therein can be cylindrical through holes. The first limiting member 51 and the second limiting member 52 are usually arranged in parallel and are closely adjacent. The height of the first limiting member 51 and the height of the second limiting member 52 are usually different, that is, the heights of the two through holes are different, so that the first limiting member 51 and the second limiting member 52 are in a stepped shape with a height difference. Generally, the height of the first limiting member 51 should be greater than the height of the second limiting member 52. The photoelectric emission tube is arranged in the through hole of the first limiting member 51, and the photoelectric emission tube does not protrude from the edge of the through hole of the first limiting member 51; the photoelectric receiving tube is arranged in the through hole of the second limiting member 52, and the photoelectric receiving tube does not protrude from the edge of the through hole of the second limiting member 52. That is to say, the photoelectric emission tube is completely recessed in the first limiting member 51, and the photoelectric receiving tube is completely recessed in the second limiting member 52.

[0040] The fixing structure 5 of the present disclosure not only helps to avoid physical damage to the photoelectric emission tube and the photoelectric receiving tube, but also helps to ensure the precise positioning between the photoelectric emission tube and the photoelectric receiving tube, ensure a stable relative position relationship between the photoelectric emission tube and the photoelectric receiving tube, and helps to ensure that the light propagation path of the infrared light emitted by the photoelectric emission tube is the same as the expected light propagation path, so as to ensure that the infrared light emitted by the photoelectric emission tube can accurately irradiate the target position (i.e., the detection area), and helps to ensure the consistency of the diffuse reflection effect, and further helps to ensure the accuracy of the electrical signal generated by the optoelectronic module 4, and finally helps to ensure the accuracy of signals such as the material picking completion information generated by the picking device.

[0041] The infrared filter 6 is fixedly arranged in the housing 1. The fixing member of the infrared filter 6 can include a card slot, a bracket, a screw fastener, etc. In one example, while fixing the optoelectronic module 4, the fixing structural member 5 can also serve as the fixing member of the infrared filter 6. The shape of the infrared filter 6 can be circular or rectangular. In one example, the shape of the infrared filter 6 can be the same as that of the light hole 7.

[0042] The infrared filter 6 is mainly used to filter out light sources other than infrared light. The infrared filter 6 is usually located on the front side of the photoelectric emission tube and the photoelectric receiving tube, and can also be only located on the front side of the photoelectric receiving tube. In one example, the infrared filter 6 can be attached to the edge position of the through holes of the first limiting member 51 and the second limiting member 52. Under the control of the core board module 2, the photoelectric emission tube emits infrared light (for example, when the picking system issues an order to the picking device, the core board module 2 controls the photoelectric emission tube to emit infrared light; another example is that after the picking device is powered on and turned on, the core board module 2 immediately controls the photoelectric emission tube to always emit infrared light until the picking device is turned off). After the infrared light passes through the infrared filter 6 located on the front side of the photoelectric emission tube, it is emitted outside the picking device through the light hole 7. When the limb (such as the hand) of the picking personnel is within the corresponding area range of the optoelectronic module 4 (which can be called the detection area range), the diffuse-reflected infrared light formed when the infrared light emitted outside the picking device irradiates the limb (such as the hand) of the picking personnel passes through the light hole 7 and then enters the photoelectric receiving tube through the infrared filter 6 located on the front side of the photoelectric receiving tube. The photoelectric receiving tube converts it into a corresponding electrical signal and transmits it to the core board module 2. By using the infrared filter 6 to filter out light sources other than infrared light, the present disclosure not only helps to improve the anti-interference ability of the optoelectronic module 4, but also the infrared filter 6 can serve as a protective layer for the optoelectronic module 4, which is beneficial to preventing the damage of components caused by strong light irradiating the optoelectronic module 4.

[0043] In one embodiment, the light aperture 7 of the present disclosure is provided on the lower bottom surface of the housing 1. That is to say, when the picking device is suspended above the picking platform, the propagation direction of the infrared light emitted by the photoelectric emission tube in the photoelectric module 4 should be downward (such as vertically downward). That is, the fixed structural member 5 fixes the photoelectric module 4 at a position where the photoelectric emission tube and the photoelectric receiving tube face downward. In one example, the vertical projections of the photoelectric emission tube and the photoelectric receiving tube should be located within the vertical projection area of the light aperture 7. Preferably, the vertical projections of the photoelectric emission tube and the photoelectric receiving tube are located in the middle area of the vertical projection area of the light aperture 7, that is, the photoelectric emission tube and the photoelectric receiving tube are arranged at positions corresponding to the middle area of the light aperture 7. By providing the light aperture 7 on the lower bottom surface of the housing 1, during the picking operation by the picking personnel, it is convenient to indicate that the picking of the materials for this order is completed. For example, when the picking personnel perform the picking operation for the order, it also indicates that the picking of the materials for this order is completed, which is beneficial to improving the convenience of use of the picking device. By arranging the positions of the photoelectric emission tube and the photoelectric receiving tube in the middle area of the light aperture 7, as much diffuse-reflected infrared light as possible is received by the photoelectric receiving tube in the photoelectric module 4, which is beneficial to improving the accuracy of the electrical signal generated by the photoelectric module 4.

[0044] In one embodiment, the housing 1 of the present disclosure includes a front cover 8 and a rear cover 9, and connecting members such as buckles and clamping grooves are respectively provided in the front cover 8 and the rear cover 9, so that the front cover 8 and the rear cover 9 can be tightly buckled together. In addition, screw holes can also be provided in the front cover 8 and the rear cover 9, so that the front cover 8 and the rear cover 9 can be tightly combined together by using fasteners such as screws. The lower bottom surfaces of the front cover 8 and the rear cover 9 together form the lower bottom surface of the housing 1, and a part of the light aperture 7 is located on the lower bottom surface of the front cover 8, and another part of the light aperture 7 is located on the lower bottom surface of the rear cover 9.

[0045] In one embodiment, the rear cover 9 is provided with at least one hook 10, such as Figure 5 and Figure 6 As shown, at least one hook 10 is provided at the lower end of the rear cover 9. The picking device is fixed on the fixing frame of the picking device through the hook 10. An example of the fixing frame of the picking device is as Figure 10 and Figure 11 shown. In addition, the rear cover 9 is also provided with a plurality of pins, such as a power supply pin 11 and a bus pin 31, such as Figure 5 and Figure 6Four pins are provided at the middle position of the rear cover 9 shown, namely two power pins 11 and two bus pins 31. When the picking device is fixed to the fixing frame of the picking device through the hook 10, the two power pins 11 and the two bus pins 31 are respectively inserted into the flexible cable 17 on the fixing frame of the picking device, so that the picking device is connected to the power supply and the picking device is connected to the picking gateway. The flexible cable can be a flexible cable formed by a 24-volt power line, a ground line, and two CAN bus-based signal lines. By providing the hook 10 and multiple pins on the rear cover 9, the present disclosure makes the installation of the picking device very convenient and enables the installation position of the picking device to be flexibly adjusted according to actual needs, which is beneficial to improving the use flexibility of the picking device.

[0046] In one embodiment, a picking button 12 and a picking indicator light are further provided on the picking device of the present disclosure, and both the picking button 12 and the picking indicator light are electrically connected to the core board module 2. The picking indicator light can be arranged in a form surrounding the picking button 12 or at the center position of the picking button 12. The picking button 12 is mainly used when the picking indicator light is on. If the picking button is pressed by the picking personnel, the core board module 2 controls the picking indicator light to go out and returns the information that the picking of the materials for this order is completed to the picking system through the CAN bus interface 3. By providing the picking button, the present disclosure provides another way to assist the picking personnel to complete the material picking for the picking device, so as to enrich the functions of the picking device and improve the robustness of the picking device.

[0047] In an example, the picking system issues an order to the picking device, and the picking indicator light is on. The core board module 2 controls the photoelectric emission tube of the photoelectric module 4 to emit infrared light. The picking personnel pick the materials according to the order. The diffuse reflection infrared light generated by the hands of the picking personnel is converted into an electrical signal by the photoelectric module 4 and transmitted to the core board module 2. The core board module 2 controls the picking indicator light to go out according to the electrical signal transmitted by the photoelectric module 4, indicating that the picking of the materials for this order is completed. If the picking indicator light does not go out due to some factors (such as abnormal photoelectric module 4, etc.), the picking personnel can selectively press the picking button 12 to make the picking indicator light go out, indicating that the picking of the materials for this order is completed. Then the picking device returns the information that the picking of the materials for this order is completed to the picking system through the CAN bus interface 3.

[0048] In one embodiment, the picking device of the present disclosure further includes: a single-chip microcomputer download interface 13. The single-chip microcomputer download interface 13 is electrically connected to the core board module 2, and the single-chip microcomputer download interface 13 can be arranged on the lower bottom surface of the housing 1. The single-chip microcomputer download interface 13 is mainly used to download programs in electronic devices such as computers or servers into the core board module 2 of the picking device. The single-chip microcomputer download interface 13 can specifically be a JTAG (Joint Test Action Group, an international standard test protocol) interface, or an SWD (Serial Wire Debug) interface, etc. The present disclosure does not limit this.

[0049] In one embodiment, the picking device of the present disclosure further includes: a plurality of function keys 14, a plurality of working indicator lights 15 (such as monochromatic indicator lights, and RGB (red, green, blue) indicator lights, etc.), and at least one digital indication module 16, etc., which are respectively connected to the core board module 2. The digital indication module 16 among them includes a plurality of digital display screens to facilitate the display of information such as time, the quantity of picked materials, or the picked material codes. The function keys 14, the working indicator lights 15, and the digital indication module 16 can be set according to actual needs, and the present disclosure does not limit this.

[0050] In one embodiment, the working process of the picking device of the present disclosure is as follows:

[0051] First, the picking device is powered on, and each hardware module in the picking device (such as a digital tube, an RGB light, a working indicator light, a function key, a photoelectric module, etc.) performs self-checking in sequence. If the functions of each hardware module are normal, the startup of the picking device is completed.

[0052] Secondly, the picking device exchanges information with the picking gateway through the CAN bus interface 3, detects the working status of the picking gateway, and waits for an order sent by the picking gateway.

[0053] Thirdly, the picking device receives the information sent by the picking gateway through the CAN bus interface 3 and parses the information. When the parsing result is an order, it controls the photoelectric emitter of the photoelectric module 4 to emit infrared light, and controls the picking indicator light to turn on to remind the picking personnel to perform the picking operation.

[0054] Finally, the picking personnel pick the corresponding materials according to the order. When the hand of the picking personnel is within the detection area of the photoelectric module 4, the photoelectric receiver receives the diffusely reflected infrared light and converts it into an electrical signal. The core board module 2 controls the photoelectric emitter to stop emitting infrared light according to this electrical signal, and at the same time controls the picking indicator light to turn off, and reports the information that the picking of this order is completed to the picking gateway, and the picking of the materials for this order ends. The picking device waits for the picking gateway to send the next order.
